    Purpose: Adrenocortical carcinoma (ACC) is a rare malignancy known for high rates of local recurrence, though the benefit of postoperative radiation therapy (RT) has not been established. In this study of grossly resected ACC, we compare local control of patients treated with surgery followed by adjuvant RT to a matched cohort treated with surgery alone. Methods and Materials: We retrospectively identified patients with localized disease who underwent R0 or R1 resection followed by adjuvant RT. Only patients treated with RT at our institution were included. Matching to surgical controls was on the basis of stage, surgical margin status, tumor grade, and adjuvant mitotane. Results: From 1991 to 2011, 360 ACC patients were evaluated for ACC at the University of Michigan (Ann Arbor, MI). Twenty patients with localized disease received postoperative adjuvant RT. These were matched to 20 controls. There were no statistically significant differences between the groups with regard to stage, margins, grade, or mitotane. Median RT dose was 55 Gy (range, 45-60 Gy). Median follow-up was 34 months. Local recurrence occurred in 1 patient treated with RT, compared with 12 patients not treated with RT (P=.0005; hazard ratio [HR] 12.59; 95% confidence interval [CI] 1.62-97.88). However, recurrence-free survival was no different between the groups (P=.17; HR 1.52; 95% CI 0.67-3.45). Overall survival was also not significantly different (P=.13; HR 1.97; 95% CI 0.57-6.77), with 4 deaths in the RT group compared with 9 in the control group. Conclusions: Postoperative RT significantly improved local control compared with the use of surgery alone in this case-matched cohort analysis of grossly resected ACC patients. Although this retrospective series represents the largest study to date on adjuvant RT for ACC, its findings need to be prospectively confirmed

    To identify the prognostically highest risk patients, DNA content and p53 nuclear or cytoplasmic accumulation, evaluated by monoclonal antibody DO7 and polyclonal antibody CM1, were determined in 94 surgically resected stage II (Dukes B2) colorectal cancers, treated or not with adjuvant 5-fluorouracil-based chemotherapy. Sixty-one (65%) of the tumors were aneuploid, 16 (17%) of which had a multiploid DNA content; 50 (53%) displayed DO7 nuclear p53 accumulation, and 44 (47%) showed cytoplasmic CM1 positivity. In multivariate analysis, only multiploidy and p53 nuclear positivity emerged as independent prognostic indicators of a poorer outcome. Positivity for p53 was associated with shorter survival in 5-fluorouracil-treated and untreated patients. Therefore, in patients with Dukes B2 colorectal cancer, a biologic profile based on the combined evaluation of DNA multiploidy and p53 status can provide valuable prognostic information, identifying patients to be enrolled in alternative, more aggressive therapeutic trials.

  6. Selective use of adjuvant radiation therapy in resectable colorectal adenocarcinoma

    Colorectal cancer recurs within the operative field in 10-20 per cent of patients undergoing potentially curative surgery. In certain subgroups, the recurrence rate is 20-50 per cent. There are some data to suggest either preoperative or postoperative radiation therapy as an adjuvant to potentially curative surgery can reduce the local operative failure rate. However, since radiation therapy has significant side effects, patient selection to maximize the therapeutic ratio is important. This report defines the criteria at the Massachusetts General Hospital for selection of patients with colorectal cancer for adjuvant radiation therapy, defines radiation therapy-surgery sequencing alternatives used, and describes techniques to reduce radiation side effects. Over a period of three and a half years, 196 patients received adjuvant radiation therapy: 51 patients received either moderate or low dose preoperative radiation therapy to rectal or rectosigmoid cancers, and 161 patients received postoperative radiation therapy to the pelvis or extrapelvic colonic tumor-lymph node beds. Some patients who received low-dose preoperative radiation therapy also received moderate-dose postoperative radiation therapy. We prefer moderate-dose postoperative radiation therapy as the approach most likely to decrease the local recurrence rate with minimal interference with surgical procedures and late small-bowel complications. Patients who received postoperative radiation therapy were those without distant metastases, whose primary tumor pathology revealed macroscopic or extensive microscopic transmural tumor penetration into extraperitoneal tissues. Careful case selection, multiple field techniques, the use of reperitonealization, omental flaps, and retroversion of the uterus into the pelvis were combined with postoperative small-bowel x-rays, bladder distention, and lateral portals to minimize radiation damage to normal structures

    Evaluating the results of controlled clinical trials, an attempt has been made to summarize the current status of adjuvant therapy in colorectal cancer. Several different adjuvant treatment approaches including immunotherapy, postoperative fibrinolysis, anticoagulation, pre- and postoperative radiotherapy when used as a single modality, have not resulted in any long-term survival benefit. Rather in contrast to previous experiences, recent prospective randomized trials have provided evidence for the efficacy of chemotherapy in the adjuvant treatment of colon and rectal cancer. Whereas its definitive role in the former disease remains somewhat controversial, for rectal cancer, it seems clear that combined modality therapy including polychemotherapy with or without radiation prolongs the disease-free interval, lowers the local recurrence rate, and may improve survival compared to surgery alone. Questions which remain to be answered by future clinical trials are related to the optimal duration and sequence of combined modality, to the role of different radiation sensitizers, and in both colon and rectal cancer, to the choice of the most effective systemtic chemotherapeutic drugs.

    Purpose: A retrospective analysis to determine differences in survival of patients with pancreatic aden carcinoma treated by radical surgery with and without adjuvant radiation therapy. Methods and Materials: Between 1980 and 1995, 249 patients with pancreatic tumors were identified at the Medical College of Ohio. Forty-four of these patients underwent radical surgical procedures with curative intent. These patients were divided into four groups according to treatment: surgery alone (n = 14), surgery plus intraoperative radiation therapy (IORT) (n = 6), surgery plus external beam radiation therapy (EBRT) (n = 14), or surgery plus both IORT and EBRT (n = 10). Outcome and survival were analyzed among the four groups. Results: The median survival time of patients treated with radical surgery alone was 6.5 months. The median survival time for the surgery plus IORT group was 9 months; however, 33.3% (two of six) of these patients survived longer than 5 years. This survival pattern was borderline significantly better than that for the surgery alone group (p = 0.0765). The surgery plus EBRT and the surgery plus IORT and EBRT groups had median survival times of 14.5 and 17.5 months, respectively. These were significantly better than that of the surgery alone group (p = 0.0004 and p = 0.0002, respectively). The addition of radiation therapy did not affect the treatment complication rate. Conclusion: The survival of patients who were treated with radical surgery alone was significantly poorer than that of patients who received adjuvant radiation therapy. These results are consistent with other studies in the literature. Patients treated with all three modalities (surgery, IORT, and EBRT) displayed the best median survival time

    Full Text Available Abstract Background Many adjuvant trials have been undertaken in an attempt to reduce the risk of recurrence among patients who undergo surgical resection for locally advanced renal cancer. However, no clear benefit has been identified to date. This systematic review was conducted to examine the exact role of adjuvant therapy in renal cancer setting. Methods Randomized controlled trials were searched comparing adjuvant therapy (chemotherapy, vaccine, immunotherapy, biochemotherapy versus no active treatment after surgery among renal cell cancer patients. Outcomes were overall survival (OS, disease-free survival (DFS, and severe toxicities. Risk ratios (RR, hazard ratios (HR and 95% confidence intervals were calculated using a fixed-effects meta-analysis. Heterogeneity was measured by I2. Different strategies of adjuvant treatment were evaluated separately. Results Ten studies (2,609 patients were included. Adjuvant therapy provided no benefits in terms of OS (HR 1.07; 95%CI 0.89 to 1.28; P = 0.48 I2 = 0% or DFS (HR 1.03; 95%CI 0.87 to 1.21; P = 0.77 I2 = 15% when compared to no treatment. No subgroup analysis (immunotherapy, vaccines, biochemotherapy and hormone therapy had relevant results. Toxicity evaluation depicted a significantly higher frequency of serious adverse events in the adjuvant group. Conclusions This analysis provided no support for the hypothesis that the agents studied provide any clinical benefit for renal cancer patients although they increase the risk of toxic effects. Randomized trials are underway to test targeted therapies, which might open a new therapeutic frontier. Until these trials yield results, no adjuvant therapy can be recommended for patients who undergo surgical resection for renal cell cancer.

    It is becoming increasingly common to incorporate chemotherapy (CT) with radiotherapy (RT) in the treatment of low-grade gliomas (LGGs) after surgical resection. However, there is a lack of literature comparing survival of patients who underwent RT or CT alone. The U.S. National Cancer Data Base was used to identify patients with histologically confirmed, World Health Organization grade 2 gliomas who received either RT alone or CT alone after surgery from 2004 to 2013. Overall survival (OS) was evaluated by Kaplan-Meier analysis, multivariable Cox proportional hazard regression, and propensity-score-matched analysis. In total, 2253 patients with World Health Organization grade 2 gliomas were included, of whom 1466 (65.1%) received RT alone and 787 (34.9%) CT alone. The median OS was 98.9 months for the RT alone group and 125.8 months for the CT alone group. On multivariable analysis, CT alone was associated with a significant OS benefit compared with RT alone (hazard ratio [HR], 0.405; 95% confidence interval, 0.277-0.592; P < 0.001). On subgroup analyses, the survival advantage of CT alone over RT alone persisted across all age groups, and for the subtotal resection and biopsy groups, but not in the gross total resection group. In propensity-score-matched analysis, CT alone still showed significantly improved OS compared with RT alone (HR, 0.612; 95% confidence interval, 0.506-0.741; P < 0.001). Our results suggest that CT alone was independently associated with longer OS compared with RT alone in patients with LGGs who underwent surgery. Copyright © 2018 Elsevier Inc. All rights reserved.

    To determine prognostic factors for and compare outcome among dogs with oral malignant melanoma following excision with or without various systemic adjuvant therapies. Retrospective case series. 151 dogs with naturally occurring oral malignant melanomas treated by excision with or without adjuvant therapies from 2001 to 2012. Case accrual was solicited from Veterinary Society of Surgical Oncology members via an email list service. Information collected from case records included signalment, tumor staging, tumor characteristics, type of surgical excision, histologic diagnosis, adjuvant therapy, and survival time. The overall median survival time was 346 days. Results of multivariate analysis indicated that tumor size, patient age, and intralesional excision (vs marginal, wide, or radical excision) were considered poor prognostic indicators. All other demographic and clinical variables were not significantly associated with survival time after adjusting for the aforementioned 3 variables. A clear survival benefit was not evident with any systemic adjuvant therapy, including vaccination against melanoma or chemotherapy; however, the number of dogs in each treatment group was small. Ninety-eight dogs received no postoperative adjuvant therapy, and there was no difference in survival time between dogs that did (335 days) and did not (352 days) receive systemic adjuvant therapy. For dogs with oral malignant melanoma, increasing tumor size and age were negative prognostic factors. Complete excision of all macroscopic tumor burden improved survival time. Long-term survival was possible following surgery alone. Although systemic adjuvant therapy was not found to improve survival time, this could have been due to type II error.

    The role of adjuvant chemotherapy for patients with stage II colon adenocarcinoma remains controversial. The high surgical cure rate for patients with "low-risk" stage II colon cancer, ranging from 75% to 80%, and the available clinical trials and meta-analyses provide conflicting recommendations for or against adjuvant chemotherapy for this group of patients. For fit "high-risk" stage II patients with clinical obstruction or perforation at presentation, in which the 5-year survival rate is 60% to 70%, there is little controversy, as these patients are routinely treated with adjuvant chemotherapy. Other potential high-risk factors, including high histologic grade, microsatellite instability, and loss of 18q, have yet to be validated in prospective trials. Patients with fewer than 12 regional lymph nodes identified in the surgical specimen have a statistically unclear risk of lymph node involvement. These patients may have stage III disease and should receive adjuvant therapy. The decision to use adjuvant chemotherapy to treat low-risk stage II colon cancer patients (no obstruction or perforation) should be an informed decision weighing the magnitude of a net 2% to 5% survival benefit, a 0.5% to 1.0% risk of mortality with chemotherapy in addition to 6 months of chemotherapy-related toxicities, other coexisting patient morbidities, and the anticipated life expectancy of each patient. As adjuvant chemotherapy is therapy addressing local or metastatic microscopic disease, and the effectiveness of systemic and biologically targeted therapy for advanced macroscopic colon cancer continues to improve rapidly, it remains to be determined by clinical trials whether therapies including newer agents such as cetuximab and bevacizumab administered in the adjuvant setting may affect survival for stage II cancer patients.

    Nowadays surgical intervention is an essential part of the treatment of idiopathic gynecomastia. Choosing the right method is crucial and is based on the current status in the clinical and histological evaluation. Before finalizing the process of choosing a specific method a prior interdisciplinary evaluation of the patient is necessary to ascertain clear indications for a surgical intervention. Liposuction is one of the methods which have become popular in recent years. The advantages are the possible combination with traditional techniques, such as subcutaneous mastectomy or periareolar mastopexy. The main indication is for gynecomastia stage IIa/b and is justifiable due to the reduction in surgical complications and scarring. Furthermore this technique provides an excellent aesthetical outcome for the patient. A total of 162 patients suffering from gynecomastia stages I-III (according to Simon) were surgically treated between 2000 and 2010 and these cases were retrospectively evaluated. The results showed a decline in the use of a T-shaped incision in combination with subcutaneous mastectomy with periareolar tightening compared to an increase in the use of subcutaneous mastectomy in combination with liposuction. The excised tissue should always be sent for histological examination to make sure no malignant cells were present.

  16. Adjuvant Biological Therapies in Chronic Leg Ulcers

    Full Text Available Current biological treatments for non-healing wounds aim to address the common deviations in healing mechanisms, mainly inflammation, inadequate angiogenesis and reduced synthesis of extracellular matrix. In this context, regenerative medicine strategies, i.e., platelet rich plasmas and mesenchymal stromal cell products, may form part of adjuvant interventions in an integral patient management. We synthesized the clinical experience on ulcer management using these two categories of biological adjuvants. The results of ten controlled trials that are included in this systematic review favor the use of mesenchymal stromal cell based-adjuvants for impaired wound healing, but the number and quality of studies is moderate-low and are complicated by the diversity of biological products. Regarding platelet-derived products, 18 controlled studies investigated their efficacy in chronic wounds in the lower limb, but the heterogeneity of products and protocols hinders clinically meaningful quantitative synthesis. Most patients were diabetic, emphasizing an unmet medical need in this condition. Overall, there is not sufficient evidence to inform routine care, and further clinical research is necessary to realize the full potential of adjuvant regenerative medicine strategies in the management of chronic leg ulcers.

    Purpose: To determine the effects of adjuvant radiotherapy and chemotherapy for carcinoma of the ampulla of Vater. Methods and Materials: We retrospectively reviewed the records of 125 patients who underwent definitive surgery for carcinomas involving the ampulla of Vater between April 1977 and February 2005 and who survived more than 50 days after surgery. Twenty-nine of the patients also received adjuvant radiotherapy (median dose, 50.4 Gy in 28 fractions) with concurrent 5-fluorouracil chemotherapy. Adverse prognostic factors were investigated, and overall survival (OS) and local and distant failure were estimated. Results: Adverse prognostic factors for decreased OS by univariate analysis included lymph node (LN) involvement, locally advanced tumors (T3/T4), and poor histologic grade. By multivariate analysis, positive LN status (p = 0.02) alone was associated with decreased OS. The addition of adjuvant radiotherapy and chemotherapy improved OS for patients with positive LN (p = 0.01). Median survival for positive LN patients receiving adjuvant therapy was 3.4 years, vs. 1.6 years for those with surgery alone. Conclusions: The addition of adjuvant radiotherapy and 5-fluorouracil chemotherapy may improve OS in patients with LN involvement. The effect of adjuvant therapy on outcomes for patients with poor histologic grade or T3/T4 tumors without LN involvement could not be assessed

    A highly effective strategy for combating infectious diseases is to enhance host defenses using immunomodulators, either preventatively, through vaccination, or therapeutically. The effectiveness of many vaccines currently in use is due in part to adjuvants, molecules that have little immunogenicity by themselves but which help enhance and appropriately skew the immune response to an antigen. The development of new vaccines necessitates the development of new types of adjuvants to ensure an appropriate immune response. Herein, we review commonly used vaccine adjuvants and discuss promising adjuvant candidates. We also discuss various other immunomodulators (namely cytokines, Toll-like receptor agonists, and host defense peptides) that are, or have potential to be, useful for antimicrobial therapies that exert their effects by boosting host immune responses rather than targeting pathogens directly.

    Full Text Available Thymic carcinomas are rare tumors for which surgical resection is the first treatment of choice. The role of adjuvant treatment after surgery is unknown because of limited available data. The present study evaluated the efficacy of post-surgery adjuvant chemotherapy or radiotherapy in patients with thymic carcinoma.To evaluate the role of adjuvant therapy in patients with thymic carcinoma, we retrospectively reviewed the records of patients with thymic carcinoma who were diagnosed and treated between 2004 and 2014.Among 78 patients with thymic carcinoma, 30 patients received surgical resection. Progression-free survival (PFS and overall survival (OS were significantly longer among these patients than among patients who received other treatments (PFS: 88.4 months vs 9.1 months, p<0.001; OS: 134.9 months vs 60.9 months; p = 0.003. Patients with stage III thymic carcinoma who received surgery had a longer OS than patients who did not receive surgery (70.1 months vs 23.9 months; p = 0.017, n = 11. Among 47 patients with stage IV carcinoma, 12 patients who received an extended thymothymectomy had a longer PFS than 35 patients who did not receive surgery (18.9 months vs 8.7 months; p = 0.029. Among 30 patients (with stage I- IV carcinoma who received primary lesion surgery, 19 patients received an R0 resection and 9 patients of the 19 patients received adjuvant radiotherapy. These patients had longer PFS (50.3 months than 2 patients who received adjuvant chemotherapy (5.9 months or 4 patients who received concurrent chemoradiotherapy (7.5 months after surgery (p = 0.003.Surgical resection should be considered for patients with thymic carcinoma, even for patients with locally advanced or stage IV carcinoma. Adjuvant radiotherapy resulted in a better PFS after R0 resection.

    BACKGROUND The role of adjuvant chemoradiation therapy (CRT) in pancreatic cancer remains controversial. The primary aim of this study was to determine if CRT improved survival in patients with resected pancreatic cancer in a large, multiinstitutional cohort of patients. STUDY DESIGN Patients undergoing resection for pancreatic adenocarcinoma from seven academic medical institutions were included. Exclusion criteria included patients with T4 or M1 disease, R2 resection margin, preoperative therapy, chemotherapy alone, or if adjuvant therapy status was unknown. RESULTS There were 747 patients included in the initial evaluation. Primary analysis was performed between patients that had surgery alone (n = 374) and those receiving adjuvant CRT (n = 299). Median followup time was 12.2 months and 14.5 months for survivors. Median overall survival for patients receiving adjuvant CRT was significantly longer than for those undergoing operation alone (20.0 months versus 14.5 months, p = 0.001). On subset and multivariate analysis, adjuvant CRT demonstrated a significant survival advantage only among patients who had lymph node (LN)-positive disease (hazard ratio 0.477, 95% CI 0.357 to 0.638) and not for LN-negative patients (hazard ratio 0.810, 95% CI 0.556 to 1.181). Disease-free survival in patients with LN-negative disease who received adjuvant CRT was significantly worse than in patients who had surgery alone (14.5 months versus 18.6 months, p = 0.034). CONCLUSIONS This large multiinstitutional study emphasizes the importance of analyzing subsets of patients with pancreas adenocarcinoma who have LN metastasis. Benefit of adjuvant CRT is seen only in patients with LN-positive disease, regardless of resection margin status. CRT in patients with LN-negative disease may contribute to reduced disease-free survival. PMID:19476845

  1. Skull base meningioma. Surgical and adjuvant treatment with clinical and PET evaluation

    International Nuclear Information System (INIS)

    Gudjonsson, O.

    2001-01-01

    The treatment strategy for skull base meningiomas remains a controversial issue. Because of the proximity of these tumours to critical neurovascular structures, the risk for vascular damage and new cranial neuropathies postoperatively is significant. To avoid unacceptable neurological deficits the surgical treatment strategy includes different surgical approaches and a subtotal removal of these tumours in some cases. However, because the rate of recurrence and progression is significant in these patients, a demand for adjuvant treatment and better prognostic methods is called for so that treatment and follow-up can be tailored to each patient. Accordingly, we have chosen to evaluate general outcome and facial nerve function after translabyrinthine and transcochlear approaches for cerebellopontine angle (CPA) meningiomas. Furthermore, we have evaluated two adjuvant treatments, namely, irradiation by high-energy proton beams and medical treatment with interferon-alpha as well as evaluation of the treatment effect with 11 C-L-methionine PET. In addition, we have evaluated a new PET tracer ( 76 Br-BrdU) for 'in vivo' determination of the growth potential of intracranial tumours. Conclusion: The translabyrinthine and transcochlear approaches are apparently safe surgical procedures in the treatment of CPA meningiomas. Proton beam therapy is technically feasible as suggested by the fact that only minimal side effects were observed. Moreover, none of the meningiomas treated have shown progression during a 36-month follow-up. Our results indicate that IFN-alpha can be an effective oncostatic treatment for certain patients with meningiomas. The 11 C-L-methionine PET method might be used as a complement to CT or MRI in the evaluation of the effect of proton beam and IFN-alpha treatment in meningiomas.

    The treatment strategy for skull base meningiomas remains a controversial issue. Because of the proximity of these tumours to critical neurovascular structures, the risk for vascular damage and new cranial neuropathies postoperatively is significant. To avoid unacceptable neurological deficits the surgical treatment strategy includes different surgical approaches and a subtotal removal of these tumours in some cases. However, because the rate of recurrence and progression is significant in these patients, a demand for adjuvant treatment and better prognostic methods is called for so that treatment and follow-up can be tailored to each patient. Accordingly, we have chosen to evaluate general outcome and facial nerve function after translabyrinthine and transcochlear approaches for cerebellopontine angle (CPA) meningiomas. Furthermore, we have evaluated two adjuvant treatments, namely, irradiation by high-energy proton beams and medical treatment with interferon-alpha as well as evaluation of the treatment effect with {sup 11}C-L-methionine PET. In addition, we have evaluated a new PET tracer ({sup 76}Br-BrdU) for 'in vivo' determination of the growth potential of intracranial tumours. Conclusion: The translabyrinthine and transcochlear approaches are apparently safe surgical procedures in the treatment of CPA meningiomas. Proton beam therapy is technically feasible as suggested by the fact that only minimal side effects were observed. Moreover, none of the meningiomas treated have shown progression during a 36-month follow-up. Our results indicate that IFN-alpha can be an effective oncostatic treatment for certain patients with meningiomas. The {sup 11}C-L-methionine PET method might be used as a complement to CT or MRI in the evaluation of the effect of proton beam and IFN-alpha treatment in meningiomas. The present attempt failed to demonstrate that the PET tracer {sup 76}Br-BrdU could be used for the non-invasive characterisation of growth potential in

    Purpose: Despite results of randomized trials that support adjuvant radiation therapy (RT) after radical prostatectomy (RP) for prostate cancer with adverse pathologic features (APF), many clinicians favor selective use of salvage RT. This survey was conducted to evaluate the beliefs and practices of radiation oncologists (RO) and urologists (U) regarding RT after RP. Methods and Materials: We designed a Web-based survey of post-RP RT beliefs and policies. Survey invitations were e-mailed to a list of 926 RO and 591 U. APF were defined as extracapsular extension, seminal vesicle invasion, or positive surgical margin. Differences between U and RO in adjuvant RT recommendations were evaluated by comparative statistics. Multivariate analyses were performed to evaluate factors predictive of adjuvant RT recommendation. Results: Analyzable surveys were completed by 218 RO and 92 U (overallresponse rate, 20%). Adjuvant RT was recommended based on APF by 68% of respondents (78% RO, 44% U, p <0.001). U were less likely than RO to agree that adjuvant RT improves survival and/or biochemical control (p < 0.0001). PSA thresholds for salvage RT were higher among U than RO (p < 0.001). Predicted rates of erectile dysfunction due to RT were higher among U than RO (p <0.001). On multivariate analysis, respondent specialty was the only predictor of adjuvant RT recommendations. Conclusions: U are less likely than RO to recommend adjuvant RT. Future research efforts should focus on defining the toxicities of post-RP RT and on identifying the subgroups of patients who will benefit from adjuvant vs. selective salvage RT.

    Purpose: To analyze the effect of adjuvant chemoradiotherapy on gallbladder carcinoma. Methods and Materials: We retrospectively reviewed the records from consecutive patients who underwent R0 resection of gallbladder carcinoma between January 1, 1985, and December 31, 2004. Patients had either Stage I (T1-T2N0M0) or Stage II (T3N0M0 or T1-T3N1M0) disease. Patients undergoing adjuvant therapy received 5-fluorouracil chemotherapy concurrently with radiotherapy (median dosage, 50.4 Gy in 28 fractions). Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) were evaluated. Results: A total of 73 patients were included in the analysis; of these, 25 received adjuvant chemoradiotherapy. On univariate analysis, no adverse prognostic factors for OS reached statistical significance, but trends were noted for Stage N1 vs. N0 (p = .06), Nx vs. N0 (p = .09), Stage T3 vs. T1-T2 (p = .06), and histologic findings other than adenocarcinoma (p = .13). The median OS for patients receiving adjuvant chemoradiotherapy vs. surgery alone was 4.8 years and 4.2 years, respectively (log-rank test, p = .56). However, a significantly greater percentage of patients receiving adjuvant chemoradiotherapy had Stage II disease (p <.001). In the multivariate Cox model, increasing T and N category and histologic findings other than adenocarcinoma were significant predictors of decreased OS. Additionally, adjuvant chemoradiotherapy was a significant predictor of improved OS after adjusting for these prognostic factors (hazard ratio for death, 0.3; 95% confidence interval, 0.13-0.69; p = .004). Conclusion: After adjusting for the stage parameters and histologic findings, our data suggest that adjuvant chemoradiotherapy might improve OS for patients with gallbladder cancer.

    valid surgical option for the treatment of pain. Though previously dismissed as a valid treatment due to the resultant brittle diabetes, the advent of islet cell autotransplantation has enabled this procedure to produce excellent long-term results in relation to pain, endocrine status and quality of life. Given these excellent short- and long-term results of surgical therapy for chronic pancreatitis, and the poor symptom control provided by conservative and endoscopic treatment (coupled to near inevitable progression to exocrine and endocrine failure), it is likely that future years will see a further shift towards the earlier and more frequent surgical treatment of chronic pancreatitis. Furthermore, the expansion of islet cell autotransplantation to a wider range of pancreatic resections has the potential to even further improve the outcomes of surgical treatment for this problematic yet increasingly common disease.

    PURPOSE: Several prospective randomized trials have shown a significant survival advantage with adjuvant chemotherapy and radiation therapy following surgical resection of adenocarcinoma of the rectum. Recent and ongoing trials are evaluating the role of modulated and/or protracted venous infusion [PVI] chemotherapy with pelvic irradiation [PRT]. The economic implications of additional therapies compared with their incremental benefits have not been rigorously analyzed. This study attempts to assess the incremental cost effectiveness of adjuvant therapy over surgery alone, and secondly, adjuvant therapy with PVI delivery systems versus rapid infusion. METHODS: A Markov model was constructed to describe the natural history of rectal carcinoma [stage B2, C] following surgical resection in a hypothetical cohort of 60 year old patients. This model was used to perform two sets of comparisons: [1] surgery alone versus adjuvant bolus fluorouracil [5-FU] with PRT, and [2] bolus 5-FU with PRT versus PVI 5-FU with PRT. Relapse rates and overall survival were derived from an early GITSG trial for the first comparison and from the NCCTG 86-47-51 trial for the second comparison. Medicare reimbursement rates and reports from health maintenance organizations were used to obtain net medical costs of adjuvant treatments, routine follow-up, advanced recurrent disease, and terminal illness as a result of rectal carcinoma. Total years of life and medical costs were projected over an 8-year time horizon for the first comparison [GITSG data] and over a 5-year time horizon for the second comparison [NCCTG data]. Monetary and nonmonetary benefits were discounted at 5% per year. Adjustments for quality of life, costs of adverse effects from treatment, and indirect costs of disease or treatment were not included in this current analysis. RESULTS: The main survival and economic outcomes for each treatment arm in the two comparisons are reported in the table below. For the first comparison

    Multiple strategies for endocrine treatment of premenopausal women with hormone-responsive breast cancer have been assessed and results have been presented over the last two years. These include tamoxifen for 5-10 years (ATLAS and aTTom), tamoxifen for 5 years followed by aromatase inhibitor (AI) for 5 years for women who have become postmenopausal (MA-17); ovarian ablation (OA) by surgery (EBCTCG overview); ovarian function suppression (OFS) by LHRH agonist (LHRH agonist meta-analysis); or combinations of approaches including OFS plus tamoxifen or AI (SOFT, TEXT, ABCSG 12 and E3193). Many of these trials have taken place in the backdrop of (neo)adjuvant chemotherapy which can confound interpretation because such therapy can suppress ovarian function either transiently or permanently. Nonetheless these trials suggest in aggregate that 10 years of tamoxifen are better than 5 years and that a program of extended adjuvant therapy of tamoxifen for 5 years followed by aromatase inhibitor for 5 years is effective for suitable candidates. The SOFT and E3193 trials do not show a major advantage for use of OFS + tamoxifen compared to tamoxifen alone. The joint SOFT/TEXT analysis and ABCGS12 trials both suggest that outcomes can be excellent with the use of combined endocrine therapy alone in properly selected patients but give conflicting results with regard to potential benefits for OFS + AI compared with OFS + tamoxifen. Further work will be needed to ascertain long-term outcomes, identify factors that predict who will benefit from extended adjuvant endocrine therapy, and assess role of OFS by medical or surgical means. It is clear, however, that endocrine therapy is a critical part of the adjuvant regimen for most premenopausal women with hormone-responsive breast cancer, and a subset of these women with luminal A-type tumors can be safely treated with endocrine therapy alone.

    Melanoma is the most common oral malignancy in dogs. This retrospective study evaluated adjuvant carboplatin chemotherapy (with or without radiation therapy) in 17 dogs with malignant oral melanoma following surgical resection. The median dosage and number of doses of carboplatin administered to the 17 dogs was 300 mg m(-2) (range, 150-300 mg m(-2)) and 4 (range, 2-11), respectively. The overall median progression-free survival for all dogs was 259 days [95% confidence interval (CI95), 119-399 days]. The first progression-free survival event was local recurrence in seven dogs (41%) and metastases in seven dogs (41%). The median overall survival for all dogs was 440 days (CI95, 247-633 days). The tumour was the cause of death in 10 dogs (59%). On the basis of this study, systemic therapy with carboplatin may be an appropriate adjunct to local treatment for canine malignant melanoma, although future prospective controlled studies are needed to compare treatment modalities for this aggressive neoplasia. © 2012 John Wiley & Sons Ltd.

    Ocular infection caused by Toxoplasma gondii, a parasite, may result in inflammation in the retina, choroid, and uvea, and consequently lead to complications such as glaucoma, cataract, and posterior synechiae. The objective of this systematic review was to assess the effects of adjunctive use of corticosteroids to anti-parasitic therapy versus anti-parasitic therapy alone for ocular toxoplasmosis. We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register (2016; Issue 11)), MEDLINE Ovid, Epub Ahead of Print, In-Process & Other Non-Indexed Citations, MEDLINE Ovid Daily (January 1946 to December 2016), Embase (January 1980 to December 2016), Latin American and Caribbean Literature on Health Sciences (LILACS (January 1982 to December 2016)), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP; www.who.int/ictrp/search/en). We used no date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 7 December 2016. We had planned to include randomized and quasi-randomized controlled trials. Eligible trials would have enrolled participants of any age who were immunocompetent and were diagnosed with acute ocular toxoplasmosis. Included trials would have compared anti-parasitic therapy plus corticosteroids versus anti-parasitic therapy alone, different doses or times of initiation of corticosteroids. Two authors independently screened titles and abstracts retrieved through the electronic searches. We retrieved full-text reports of studies categorized as 'unsure' or 'include' after we reviewed the abstracts. Two authors independently reviewed each full-text report for eligibility. Discrepancies were resolved through discussion. We identified no completed or ongoing trial that was eligible for this Cochrane review. Although research has identified a wide

    To evaluate the effect of adjuvant external beam radiation therapy (EBRT) on local failure-free survival rate (LFFS) for papillary thyroid cancer (PTC) invading the trachea. Fifty-six patients with locally advanced PTC invading the trachea were treated with surgical resection. After surgery, 21 patients received adjuvant EBRT and radioactive iodine therapy (EBRT group) and 35 patients were treated with radioactive iodine therapy (control group). The age range was 26–87 years (median, 56 years). The median follow-up period was 43 months (range, 4 to 145 months). EBRT doses ranged from 50.4 to 66 Gy (median, 60 Gy). Esophagus invasion and gross residual disease was more frequent in the EBRT group. In the control group, local recurrence developed in 9 (9/35, 26%) and new distant metastasis in 2 (2/35, 6%) patients, occurring 4 to 68 months (median, 37 months) and 53 to 68 months (median, 60 months) after surgery, respectively. Two patients had simultaneous local recurrence and new distant metastasis. There was one local failure in the EBRT group at 18 months after surgery (1/21, 5%). The 5-year LFFS was 95% in the EBRT group and 63% in the control group (p = 0.103). In the EBRT group, one late grade 2 xerostomia was developed. Although, EBRT group had a higher incidence of esophagus invasion and gross residual disease, EBRT group showed a better 5-year LFFS. Adjuvant EBRT may have contributed to the better LFFS in these patients.

    Surgery represents the only potential curative treatment option for patients diagnosed with pancreatic adenocarcinoma. Despite aggressive surgical management for patients deemed to be resectable, rates of local recurrence and/or distant metastases remain high, resulting in poor long-term outcomes. In an effort to reduce recurrence rates and improve survival for patients having undergone resection, adjuvant therapies (ATs) including chemotherapy and chemoradiation therapy (CRT) have been explored. While adjuvant chemotherapy has been shown to consistently improve outcomes, the data regarding adjuvant radiation therapy (RT) is mixed. Although the ability of radiation to improve local control has been demonstrated, it has not always led to improved survival outcomes for patients. Early trials are flawed in their utilization of sub-optimal radiation techniques, limiting their generalizability. Recent and ongoing trials incorporate more optimized RT approaches and seek to clarify its role in treatment strategies. At the same time novel radiation techniques such as intensity modulated RT (IMRT) and stereotactic body RT (SBRT) are under active investigation. It is hoped that these efforts will lead to improved disease-related outcomes while reducing toxicity rates.

    Purpose/Objective: To determine the role of intraperitoneal radioactive chromic phosphate (P-32) in the treatment of patients with ovarian carcinoma. Survival results, patterns of recurrence, and treatment morbidity are reported for patients treated adjuvantly after primary surgery and for patients treated with the intent of consolidation after second-look laparotomy. Materials and Methods: Between 1976 and 1993, 25 patients with ovarian carcinoma were treated with 15 mCi P-32 as adjuvant therapy and 43 patients received P-32 as consolidation after second-look laparotomy. The majority of patients (13 of 19) treated adjuvantly had high-risk early-stage disease (IAG 3, IBG 2-3, IC) or more advanced stages (6 patients). Thirty-nine patients received consolidative P-32 after negative second-look laparotomy (35 Stage II-IV and 4 Stage I) and 4 Stage III patients were treated after positive second-look laparotomy. All patients had 2-year minimum follow-up (median, 7.9 years). Results: Ten-year abdominal control and cause-specific survival rates for adjuvant P-32 were 83% and 82%, respectively. For patients treated with consolidative P-32, 5-year abdominal control and cause-specific survival rates were 65% and 78%, respectively. The 5-year cause-specific survival rate for 35 patients with Stage II-IV disease treated with consolidative P-32 after negative second-look laparotomy was 81%. A component of peritoneal failure was the primary mode of recurrence (15 of 22 failures). Four patients required surgical intervention for small-bowel obstruction. No patients died of treatment-related complications. Conclusion: P-32 is well tolerated with acceptable toxicity. In comparing our results to the literature, adjuvant P-32 appears to offer improved cause-specific survival compared with observation alone and equivalent cause-specific survival compared with adjuvant chemotherapy. Consolidative P-32 after negative second-look laparotomy resulted in improved 5-year cause

    Endoscopic Nd-YAG laser treatment and adjuvant therapy were performed in 44 cases with metastatic lesions of airway. The best results were obtained in 31 cases (93.9%) out of 33 cases complaining of ventilatory disturbance in which endoscopic Nd-YAG laser treatment was indicated as an emergency procedure. In most of these cases with metastatic lesions of airway consisted of respiratory tract invasion from mediastinal lymph nodes in cases of esophageal cancer or lung cancer. In these cases, after laser treatment for ventilatory disturbance, the patients condition improved to the extent that adjuvant therapy could be performed. Adjuvant therapy was performed in 38 cases, there were 7 cases treated surgically resection of the metastatic lesions of airway in 3 cases, tracheal tube stent operation in 4 cases 0, 28 radiotherapy in 28 cases Linac irradiation in 24 cases, /sup 60/Co intraluminal irradiation of the trachea in 4 cases 0, and 32 cases were treated with chemotherapy. Tracheal tube stent operation was useful for maintenance of the tracheal lumen following laser treatment, and /sup 60/Co intraluminal irradiation was effective for the residual intratracheal tumor. The 1-year survival rate of 44 cases with metastatic lesions of airway was 42% and the 2-year survival rate was 22%, so this result suggested endoscopic Nd-YAG laser treatment and adjuvant therapy for metastatic lesions of airway was useful to prolong survival time. However the main value of this modality is for the rapid relief of severe ventilatory disturbance due to obstructive airway lesions. (author).

    Full Text Available Background: Adjuvant therapy after curative resection is associated with survival benefit in stage III pancreatic cancer. We analyzed the factors affecting the outcome of adjuvant therapy in stage III pancreatic cancer and compared overall survival with different modalities of adjuvant treatment. Methods: This is a retrospective study of patients with stage III pancreatic cancer listed in the National Cancer Database (NCDB who were diagnosed between 2004 and 2012. Patients were stratified based on adjuvant therapy they received. Unadjusted Kaplan-Meier and multivariable Cox regression analysis were performed. Results: We analyzed a cohort included 1731 patients who were recipients of adjuvant therapy for stage III pancreatic cancer within the limits of our database. Patients who received adjuvant chemoradiation had the longest postdiagnosis survival time, followed by patients who received adjuvant chemotherapy, and finally patients who received no adjuvant therapy. On multivariate analysis, advancing age and patients with Medicaid had worse survival, whereas Spanish origin and lower Charlson comorbidity score had better survival. Conclusions: Our study is the largest trial using the NCDB addressing the effects of adjuvant therapy specifically in stage III pancreatic cancer. Within the limits of our study, survival benefit with adjuvant therapy was more apparent with longer duration from date of diagnosis.

    To evaluate the benefit of adjuvant radiation therapy (RT) for retroperitoneal liposarcoma (RPLS) following gross tumor removal. We reviewed 77 patients with primary RPLS surgically treated between January 2000 and December 2013. Cases with gross residual disease were excluded. Tumor grade was evaluated according to the French Federation of Cancer Centers Sarcoma Group (FNCLCC) system. Adjuvant RT was delivered to 32 patients (42%) using external beam RT alone. Median follow-up time was 36 months (range, 5 to 169). Among 77 patients, 33 (43%) presented with well-differentiated, 31 (40%) with de-differentiated, 8 (10%) with myxoid/round and 4 (5%) with pleomorphic morphology. The RT group included less well-differentiated subtype than surgery group (28% vs. 53%). During follow up, 34 patients (44%) showed local recurrence. Local recurrence rate was lower in the RT group (38%) compared to the surgery group (49%). The 3-year local control rate (LC) was 55.6%, and the 3-year overall survival (OS) was 82.1%. Tumor histology and FNCLCC grade were significantly associated with local recurrence. There was no statistical significance of adding adjuvant RT in LC (p = 0.312). However, patients with tumor histology other than well-differentiated subtype showed marginally decreased local recurrence rate after adjuvant RT (3-year LC, RT 43.9% vs. no RT 35.3%; p = 0.087). RPLS patients receiving RT experienced less local recurrence. We suggest that the addition of adjuvant RT may be related to improvement of LCs, especially in patients with non-favorable histologic subtypes.

    Initial randomised studies of chemotherapy and endocrine therapy showed that systemic treatments had a substantial impact on the survival of women with early breast cancer. The original assumption was that the efficacy of these treatments was limited to those patients presenting with more adverse prognostic features. Subsequently, meta-analyses of randomised trials revealed that the benefits of chemotherapy and endocrine therapy are not mutually exclusive and extend to all the prognostic subgroups. However, the absolute benefit varies according to baseline characteristics such as tumour stage and other biological factors. Over the last 10 years, considerable progress has been made with the introduction of new drugs into the adjuvant and neoadjuvant treatment of women with breast cancer. Taxanes and third-generation aromatase inhibitors are providing proof of additional benefits compared with standard reference treatments. In parallel, research on the biology of breast cancer is establishing novel prognostic and predictive factors, which may allow better treatment tailoring. Currently, however, women with early breast cancer and their doctors face the difficult task of making therapeutic decisions often based on early results from positive studies. In a disease where follow up is crucial to fully assess the benefit and long-term toxicities of an intervention, current knowledge leaves unanswered questions that generate debate and controversy. This review will summarise recent results from randomised trials of adjuvant and neoadjuvant therapy in women with early breast cancer and focus on the current controversies.

    This paper presents long-term results from a randomized trial of pre- or postoperative megavoltage radiation therapy versus surgery alone in pre- and postmenopausal women with operable breast cancer. Treatment outcome after relapse among patients who developed loco-regional recurrences was also analyzed. A total of 960 patients were included in the trial. The mean follow-up was 16 years (range: 13-19 years). The radiation therapy was individually planned. It included the chest wall (and the breast in the preoperative cases) and the regional lymph nodes. The tumor dose was 45 Gy/5 weeks. No adjuvant systemic therapy was used. The results showed a significant benefit with radiation therapy in terms of recurrence-free survival during the entire follow-up period. There was also an overall survival difference - corresponding to 16% reduction of deaths - in favour of the irradiated patients which, however, was not statistically significant (p=0.09). Among those 169 patients who developed loco-regional recurrences long-term control was only achieved in about one-third of the cases. This figure was similar among those who had received adjuvant radiation therapy (34%) compared to those initially treated with surgery alone (32%). This implied that the overall proportion of patients who eventually developed uncontrolled local disease was significantly higher among those initially allocated to surgery alone (16%) compared to those allocated to pre- or postoperative radiation therapy (6%, p<0.01). These results suggest that local undertreatment may be deleterious in subgroups of patients. (author) 5 tabs

    Purpose: The purpose of this guideline was to provide a clinical framework for the use of radiation therapy after radical prostatectomy as adjuvant or salvage therapy. Methods and Materials: A systematic literature review using PubMed, Embase, and Cochrane database was conducted to identify peer-reviewed publications relevant to the use of radiation therapy after prostatectomy. The review yielded 294 articles; these publications were used to create the evidence-based guideline statements. Additional guidance is provided as Clinical Principles when insufficient evidence existed. Results: Guideline statements are provided for patient counseling, use of radiation therapy in the adjuvant and salvage contexts, defining biochemical recurrence, and conducting a restaging evaluation. Conclusions: Physicians should offer adjuvant radiation therapy to patients with adverse pathologic findings at prostatectomy (ie, seminal vesicle invastion, positive surgical margins, extraprostatic extension) and salvage radiation therapy to patients with prostate-specific antigen (PSA) or local recurrence after prostatectomy in whom there is no evidence of distant metastatic disease. The offer of radiation therapy should be made in the context of a thoughtful discussion of possible short- and long-term side effects of radiation therapy as well as the potential benefits of preventing recurrence. The decision to administer radiation therapy should be made by the patient and the multidisciplinary treatment team with full consideration of the patient's history, values, preferences, quality of life, and functional status. The American Society for Radiation Oncology and American Urological Association websites show this guideline in its entirety, including the full literature review.

    Although protracted cognitive impairment has been reported to occur after radiotherapy even when such therapy is not directed to brain areas, the mechanism remains unclear. This study investigated whether breast cancer patients exposed to local radiotherapy showed lower cognitive function mediated by higher plasma interleukin (IL)-6 levels than those unexposed. We performed the Wechsler Memory Scale-Revised (WMS-R) and measured plasma IL-6 levels for 105 breast cancer surgical patients within 1 year after the initial therapy. The group differences in each of the indices of WMS-R were investigated between cancer patients exposed to adjuvant regional radiotherapy (n = 51) and those unexposed (n = 54) using analysis of covariance. We further investigated a mediation effect by plasma IL-6 levels on the relationship between radiotherapy and the indices of WMS-R using the bootstrapping method. The radiotherapy group showed significantly lower Immediate Verbal Memory Index and Delayed Recall Index (P = 0.001, P = 0.008, respectively). Radiotherapy exerted an indirect effect on the lower Delayed Recall Index of WMS-R through elevation of plasma IL-6 levels (bootstrap 95% confidence interval = −2.6626 to −0.0402). This study showed that breast cancer patients exposed to adjuvant regional radiotherapy in conservation therapy might have cognitive impairment even several months after their treatment. The relationship between the therapy and the cognitive impairment could be partially mediated by elevation of plasma IL-6 levels

    Angiosarcoma is an extremely rare, high-grade malignancy, which accounts for <2% of all soft-tissue sarcomas. Cases of primary renal angiosarcoma represent 1% of these. Angiosarcomas involving the kidney usually originate from metastatic skin lesions or primary visceral lesions and most often occur in the sixth and seventh decades of life. The present study describes a case of primary renal angiosarcoma that presented as a large right-sided renal mass with symptoms of flank pain. Despite surgical removal of the tumor, recurrent disease with associated lung metastases was identified at the surgical site following adjuvant chemotherapy. The patient succumbed to the disease 13 months after the diagnosis. PMID:25789072

    The role of adjuvant radiotherapy for central neurocytomas (CNs) is not clear. Therefore, we aimed to examine the clinical outcomes of treating histologically confirmed CNs with adjuvant RT after surgical resection. Sixty-three CN patients were retrospectively evaluated: 24 patients underwent gross total resection (GTR); 28, subtotal resection (STR); 9, partial resection (PR), and 2, biopsy (Bx). They underwent adjuvant RT after surgery (median dose, 54 Gy). The median follow-up was 69 months (15–129 months). The 5-year overall survival (OS) and 5-year progression-free survival (PFS) were 94.4% and 95% after GTR + RT, 96.4% and 100% after STR + RT, and 100% and 90.9% after PR + RT. Only three patients had tumor recurrence: at the primary site at 30 and 24 months in two GTR + PR patients, and dissemination to the spinal cord at 75 months in one STR + RT patient. Thirty-eight (63.3%) patients experienced late neurotoxicity (28, grade 1; 7, grade 2; 3, grade 3). Short-term memory impairment was the most common toxicity. RT after incomplete resection (IR) led to OS and PFS comparable to those for GTR. Considering the excellent outcomes and limited late toxicity, adjuvant RT maybe a good option for CN patients who undergo IR

  7. Probiotics as an adjuvant treatment in Helicobacter pylori eradication therapy.

    Over 80% of individuals infected with Helicobacter pylori (H. pylori) are asymptomatic. Increased resistance to antibiotics and decreased compliance to the therapeutic regimens have led to the failure of eradication therapy. Probiotics, with direct and indirect inhibitory effects on H. pylori in both animal models and clinical trials, have recently been used as a supplementary treatment in H. pylori eradication therapy. Probiotics have been considered useful because of the improvements in H. pylori eradication rates and therapy-related side effects although treatment outcomes using probiotics are controversial due to the heterogeneity of species, strains, doses and therapeutic duration of probiotics. Thus, despite the positive role of probiotics, several factors need to be further considered during their applications. Moreover, adverse events of probiotic use need to be noted. Further investigations into the safety of adjuvant probiotics to H. pylori eradication therapy are required. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Purpose: Pure tubular carcinoma of the breast (PTCB) represents a distinct subtype of invasive ductal carcinoma (IDC) that is generally thought to be associated with better prognosis than even low-grade IDC. There has been controversy as to the role of adjuvant radiation therapy (RT) in this population. We hypothesized that adjuvant RT would demonstrate a survival improvement. Methods and Materials: We queried the Surveillance, Epidemiology and End Results database for the years 1992-2007 to identify patients with pure tubular carcinomas of the breast. Patient demographics, tumor characteristics, and surgical and RT treatments were collected. Survival analysis was performed using the Kaplan-Meier method for univariate comparisons and Cox proportional hazards modeling for multivariate comparisons, stratifying on the basis of age with a cutoff age of 65. Results: A total of 6465 patients were identified: 3624 (56.1%) patients underwent lumpectomy with RT (LUMP+RT), 1525 (23.6%) patients underwent lumpectomy alone (LUMP), 1266 (19.6%) patients received mastectomy alone (MAST), and 50 (0.8%) patients underwent mastectomy with RT (MAST+RT). When we compared the LUMP+RT and LUMP groups directly, those receiving adjuvant RT tended to be younger and were less likely to be hormone receptor-positive. Overall survival was 95% for LUMP+RT and 90% for LUMP patients at 5 years. For those 65 or younger, the absolute overall survival benefit of LUMP+RT over LUMP was 1% at 5 years and 3% at 10 years. On stratified multivariate analysis, adjuvant RT remained a significant predictor in both age groups (P=.003 in age {<=}65 and P=.04 in age >65 patients). Other significant unfavorable factors were older age and higher T stage (age >65 only). Conclusions: Since sufficiently powered large scale clinical trials are unlikely, we would recommend that adjuvant radiation be considered in PTCB patients age 65 or younger, although consideration of the small absolute survival benefit is

  9. Adjuvant psychological therapy in long-term endocrine conditions.

    Consideration of psychological distress in long-term endocrine conditions is of vital importance given the prevalence of anxiety and depression in such disorders. Poor mental health can lead to compromised self-care, higher utilization of health services, lower rates of adherence, reduced quality of life and ultimately poorer outcomes. Adjuvant psychological therapy offers an effective resource to reduce distress in endocrine conditions. While the vast majority of work in this area has focused on psychological screening and intervention in diabetes, identification and recognition of psychological distress are equally important in other endocrinological conditions, with supportive evidence in polycystic ovary syndrome and Addison's disease. Referral pathways and recommendations set out by UK guidelines and the Department of Health mandate requires greater attention across a wider range of long-term endocrine conditions to facilitate improved quality of life and health outcome. © 2017 John Wiley & Sons Ltd.

    Purpose: The optimal management of oral cavity squamous cell carcinoma (OCSCC) typically involves surgical resection followed by adjuvant radiotherapy or chemoradiotherapy (CRT) in the setting of adverse pathologic features. Intensity-modulated radiation therapy (IMRT) is frequently used to treat oral cavity cancers, but published IMRT outcomes specific to this disease site are sparse. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for OCSCC. Methods and Materials: Retrospective study of all patients treated at Dana-Farber Cancer Institute for OCSCC with adjuvant or definitive IMRT between August 2004 and December 2009. The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1-3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

    The optimal chemotherapy regimen administered concurrently with preoperative radiation therapy (RT) for patients with rectal cancer is unknown. National Surgical Adjuvant Breast and Bowel Project trial R-04 compared four chemotherapy regimens administered concomitantly with RT. Patients with clinical stage II or III rectal cancer who were undergoing preoperative RT (45 Gy in 25 fractions over 5 weeks plus a boost of 5.4 Gy to 10.8 Gy in three to six daily fractions) were randomly assigned to one of the following chemotherapy regimens: continuous intravenous infusional fluorouracil (CVI FU; 225 mg/m(2), 5 days per week), with or without intravenous oxaliplatin (50 mg/m(2) once per week for 5 weeks) or oral capecitabine (825 mg/m(2) twice per day, 5 days per week), with or without oxaliplatin (50 mg/m(2) once per week for 5 weeks). Before random assignment, the surgeon indicated whether the patient was eligible for sphincter-sparing surgery based on clinical staging. The surgical end points were complete pathologic response (pCR), sphincter-sparing surgery, and surgical downstaging (conversion to sphincter-sparing surgery). From September 2004 to August 2010, 1,608 patients were randomly assigned. No significant differences in the rates of pCR, sphincter-sparing surgery, or surgical downstaging were identified between the CVI FU and capecitabine regimens or between the two regimens with or without oxaliplatin. Patients treated with oxaliplatin experienced significantly more grade 3 or 4 diarrhea (P < .001). Administering capecitabine with preoperative RT achieved similar rates of pCR, sphincter-sparing surgery, and surgical downstaging compared with CVI FU. Adding oxaliplatin did not improve surgical outcomes but added significant toxicity. The definitive analysis of local tumor control, disease-free survival, and overall survival will be performed when the protocol-specified number of events has occurred. © 2014 by American Society of Clinical Oncology.

    2005-01-01

    Purpose To determine the efficacy and complications of adjuvant vaginal high-dose-rate brachytherapy alone for patients with Stage I endometrial cancer in whom complete surgical staging had been performed. Methods and Materials Between April 1998 and March 2004, 100 patients with Stage I endometrial cancer underwent surgical staging (total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic ± paraaortic nodal sampling) and postoperative vaginal high-dose-rate brachytherapy at our institution. The total dose was 2100 cGy in three fractions. Results With a median follow-up of 23 months (range 2-62), no pelvic or vaginal recurrences developed. All patients underwent pelvic dissection, and 42% underwent paraaortic nodal dissection. A median of 29.5 pelvic nodes (range 1-67) was removed (84% had >10 pelvic nodes removed). Most patients (73%) had endometrioid (or unspecified) adenocarcinoma, 16% had papillary serous carcinoma, and 11% had other histologic types. The International Federation of Gynecology and Obstetrics stage and grade was Stage IA, grade III in 5; Stage IB, grade I, II, or III in 6, 27, or 20, respectively; and Stage IC, grade I, II, or III in 13, 17, or 10, respectively. The Common Toxicity Criteria (version 2.0) complications were mild (Grade 1-2) and consisted primarily of vaginal mucosal changes, temporary urinary irritation, and temporary diarrhea. Conclusion Adjuvant vaginal high-dose-rate brachytherapy alone may be a safe and effective alternative to pelvic external beam radiotherapy for surgical Stage I endometrial cancer

    Purpose: Large randomized trials have demonstrated significant survival benefits with the use of adjuvant chemotherapy or chemoradiation therapy for gastric cancer. The importance of adjuvant radiation therapy (RT) remains unclear. We performed an up-to-date meta-analysis of randomized trials testing the use of RT for resectable gastric cancer. Methods and Materials: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials testing adjuvant (including neoadjuvant) RT for resectable gastric cancer. Hazard ratios describing the impact of adjuvant RT on overall survival (OS) and disease-free survival (DFS) were extracted directly from the original studies or calculated from survival curves. Pooled estimates were obtained using the inverse variance method. Subgroup analyses were performed to determine whether the efficacy of RT varies with chemotherapy use, RT timing, geographic region, type of nodal dissection performed, or lymph node status. Results: Thirteen studies met all inclusion criteria and were used for this analysis. Adjuvant RT was associated with a significant improvement in both OS (HR = 0.78, 95% CI: 0.70-0.86, P<.001) and DFS (HR = 0.71, 95% CI: 0.63-0.80, P<.001). In the 5 studies that tested adjuvant chemoradiation therapy against adjuvant chemotherapy, similar effects were seen for OS (HR = 0.83, 95% CI: 0.67-1.03, P=.087) and DFS (HR = 0.77, 95% CI: 0.91-0.65, P=.002). Available data did not reveal any subgroup of patients that does not benefit from adjuvant RT. Conclusion: In randomized trials for resectable gastric cancer, adjuvant RT provides an approximately 20% improvement in both DFS and OS. Available data do not reveal a subgroup of patients that does not benefit from adjuvant RT. Further study is required to optimize the implementation of adjuvant RT for gastric cancer with regard to patient selection and integration with systemic therapy

    Women with a diagnosis of breast cancer may experience short- and long-term disease and treatment-related adverse physiological and psychosocial outcomes. These outcomes can negatively impact prognosis, health-related quality of life (HRQoL), and psychosocial and physical function. Physical activity may help to improve prognosis and may alleviate the adverse effects of adjuvant therapy. To assess effects of physical activity interventions after adjuvant therapy for women with breast cancer. We searched the Cochrane Breast Cancer Group (CBCG) Specialised Registry, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Physiotherapy Evidence Database (PEDro), SPORTDiscus, PsycINFO, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform, on 18 September 2015. We also searched OpenGrey and Healthcare Management Information Consortium databases. We searched for randomised and quasi-randomised trials comparing physical activity interventions versus control (e.g. usual or standard care, no physical activity, no exercise, attention control, placebo) after adjuvant therapy (i.e. after completion of chemotherapy and/or radiation therapy, but not hormone therapy) in women with breast cancer. Two review authors independently selected studies, assessed risk of bias, and extracted data. We contacted trial authors to ask for additional information when needed. We calculated an overall effect size with 95% confidence intervals (CIs) for each outcome and used GRADE to assess the quality of evidence for the most important outcomes. We included 63 trials that randomised 5761 women to a physical activity intervention (n = 3239) or to a control (n = 2524). The duration of interventions ranged from 4 to 24 months, with most lasting 8 or 12 weeks (37 studies). Twenty-eight studies included aerobic exercise only, 21 involved aerobic

    The present paper provides a review of the available non-surgical treatments for Peyronie's disease (PD). A review of published literature on oral, intralesional, external energy and iontophoresis therapies for PD was performed, and the published results of available treatment options reviewed. The authors recommendations for appropriate non-surgical management of PD are provided. Although there are many published reports that show the efficacy of non-surgical therapies for PD, there is a lack of large scale, multicenter controlled clinical trials, which makes treatment recommendations difficult. Careful review of the literature does suggest that there are treatment options that make scientific sense and appear to stabilize the disease process, reduce deformity, and improve function. Offering no treatment at all will encourage our patients to pursue alternative treatments, which might do harm, and misses the opportunity to do some good. Clearly further work is necessary to develop safe and effective non-surgical treatments for PD.

    Petryk, Alicia Ailie

    Magnetic nanoparticle hyperthermia (mNPH) is an emerging cancer therapy which has shown to be most effective when applied in the adjuvant setting with chemotherapy, radiation or surgery. Although mNPH employs heat as a primary therapeutic modality, conventional heat may not be the only cytotoxic effect. As such, my studies have focused on the mechanism and use of mNPH alone and in conjunction with cisplatinum chemotherapy in murine breast cancer cells and a related in vivo model. MNPH was compared to conventional microwave tumor heating, with results suggesting that mNPH (mNP directly injected into the tumor and immediately activated) and 915 MHz microwave hyperthermia, at the same thermal dose, result in similar tumor regrowth delay kinetics. However, mNPH shows significantly less peri-tumor normal tissue damage. MNPH combined with cisplatinum also demonstrated significant improvements in regrowth delay over either modality applied as a monotherapy. Additional studies demonstrated that a relatively short tumor incubation time prior to AMF exposure (less than 10 minutes) as compared to a 4-hour incubation time, resulted in faster heating rates, but similar regrowth delays when treated to the same thermal dose. The reduction of heating rate correlated well with the observed reduction in mNP concentration in the tumor observed with 4 hour incubation. The ability to effectively deliver cytotoxic mNPs to metastatic tumors is the hope and goal of systemic mNP therapy. However, delivering relevant levels of mNP is proving to be a formidable challenge. To address this issue, I assessed the ability of cisplatinum to simultaneously treat a tumor and improve the uptake of systemically delivered mNPs. Following a cisplatinum pretreatment, systemic mNPs uptake was increased by 3.1 X, in implanted murine breast tumors. Additional in vitro studies showed the necessity of a specific mNP/ Fe architecture and spatial relation for heat-based cytotoxicity in cultured cells.

    The present retrospective study evaluated the recurrence patterns after aggressive surgical removal of intracranial glioblastomas in 43 consecutive adult patients. The resection rate of the enhanced lesion on magnetic resonance imaging was 100% and 95-99% in 22 and 21 cases, respectively. All patients received postoperative fractionated radiotherapy (60 Gy in 30 fractions) with additional chemotherapy (25 cases) or vaccine therapy (18 cases). During follow-up (median 17 months), tumor recurrence was identified in 33 patients, most frequently regional within the wall of the resection cavity (20 cases). No clinical factor differed significantly between the groups of patients with regional or marginal tumor progression (N=22) and patients with distant or multiple recurrences (N=8). Progression-free survival did not differ significantly between these two groups (p=0.27). However, overall survival was significantly longer (p=0.04) in patients with regional or marginal tumor progression, and constituted 90% and 54% at 1 and 2 years after surgery, respectively, compared to 75% and 0% in patients with distant or multiple recurrences. Aggressive surgical resection and adjuvant management of intracranial glioblastoma may change its recurrence pattern. Tumor progression appears in the wall of the resection cavity or within 2 cm from its margin in approximately half of patients. (author)

    Purpose: Pancreatic neuroendocrine tumors (pNET) are rare neoplasms associated with poor outcomes without resection, and involved surgical margins are associated with a worse prognosis. The role of adjuvant radiotherapy (RT) in these patients has not been characterized. Methods and Materials: We retrospectively evaluated 46 consecutive patients with positive or close (<1 mm) margins after pNET resection, treated from 1983 to 2010, 16 of whom received adjuvant RT. Median RT dose was 50.4 Gy in 1.8-Gy fractions; half the patients received concurrent chemotherapy with 5-fluorouracil or capecitabine. No patients received adjuvant chemotherapy. Cox multivariate analysis (MVA) was used to analyze factors associated with overall survival (OS). Results: Median age at diagnosis was 56 years, and 52% of patients were female. Median tumor size was 38 mm, 57% of patients were node-positive, and 11% had a resected solitary liver metastasis. Patients who received RT were more likely to have larger tumors (median, 54 mm vs. 30 mm, respectively, p = 0.002) and node positivity (81% vs. 33%, respectively, p = 0.002) than those not receiving RT. Median follow-up was 39 months. Actuarial 5-year OS was 62% (95% confidence interval [CI], 41%-77%). In the group that did not receive RT, 3 patients (10%) experienced local recurrence (LR) and 5 patients (18%) developed new distant metastases, while in the RT group, 1 patient (6%) experienced LR and 5 patients (38%) developed distant metastases. Of all recurrences, 29% were LR. On MVA, male gender (adjusted hazard ratio [AHR] = 3.81; 95% CI, 1.21-11.92; p = 0.02) and increasing tumor size (AHR = 1.02; 95% CI, 1.01-1.04; p = 0.007) were associated with decreased OS. Conclusions: Long-term survival is common among patients with involved-margin pNET. Despite significantly worse pathologic features among patients receiving adjuvant RT, rates of LR between groups were similar, suggesting that RT might aid local control, and merits further

    Gastric cancer is one of the main cancer-related causes of death worldwide. The curative treatment of gastric cancer consists of tumor resection and lymphadenectomy. However, surgical treatment alone is associated with high recurrence rates. Adjuvant treatment strategies have been studied over the last decades, but there have been controversial results from the initial studies. The pivotal INT0116 study demonstrated that the use of adjuvant chemoradiotherapy with 5-fluorouracil increases relapse-free and overall survival, and it has been adopted across the Western world. The high toxicity of radiochemotherapy and suboptimal surgical treatment employed, with fewer than 10% of the patients submitted to D2 lymphadenectomy, were the main study limitations. Since its publication, other adjuvant treatment modalities have been studied, and radiochemotherapy is being refined to improve its efficacy and safety. A multimodal approach has been demonstrated to significantly increase relapse-free and overall survival, and it can be offered in the form of perioperative chemotherapy, adjuvant chemoradiotherapy or adjuvant chemotherapy, regardless of the extent of lymphadenectomy. The objective of the present review is to report the major advances obtained in the last decades in the adjuvant treatment of gastric cancer as well as the perspectives of treatment based on recent knowledge of the molecular biology of the disease.

    The success of targeted therapies, including inhibitors of the vascular endothelial growth factor pathway or the mammalian target of rapamycin, in the treatment of metastatic renal cell carcinoma led to interest in testing their efficacy in the adjuvant setting. Results from the first trials are now available, with other studies due to report imminently. This review provides an overview of adjuvant targeted therapy in renal cell carcinoma, including interpretation of currently available conflicting data and future direction of research. We discuss the key differences between the completed targeted therapy adjuvant trials, and highlight the importance of accurately identifying patients who are likely to benefit from adjuvant treatment. We also consider reasons why blinded independent radiology review and treatment dose may prove critical for adjuvant treatment success. The implications of using disease-free survival as a surrogate end point for overall survival from the patient perspective and measurement of health benefit have recently been brought into focus and are discussed. Finally, we discuss how the ongoing adjuvant trials with targeted therapies and checkpoint inhibitors may improve our understanding and ability to prevent tumor recurrence after nephrectomy in the future.

    Full Text Available Background: Adjuvant 5-fluorouracil (5FU-based chemo-radiotherapy is currently considered a standard of care for the treatment of gastric cancer. The impact of 5FU-based adjuvant therapy on the rate of distant recurrence has been modest. In order to improve the systemic effects of adjuvant therapy, we have been treating patients with resected gastric cancer with carboplatin and paclitaxel followed by fluoropyrimidine analogue and radiation. Methods: We report on the outcomes of 21 consecutive gastric cancer patients treated off protocol with adjuvant carboplatin (area under the curve 5 mg/ml × min and paclitaxel (175–200 mg/m2 every 3 weeks, followed by concurrent pyrimidine analogs (either capecitabine 1,600–2,000 mg/m2/day in 17 patients, or 5FU 200 mg/m2/day in 4 patients and radiation (45–50.4 Gy. Patients received a total of 4–6 cycles of carboplatin and paclitaxel. Results: The median age at diagnosis was 60 years. Sixteen patients had stage 3 disease and 7 of them had positive surgical margins (6 with R1 and 1 with R2 resection, 3 patients were stage 2, and 2 patients were stage 1 (all had R0 resection. All patients had D1/D2 (4 had D2 and 17 had D1 lymph node dissection. The incidence of grade 3 or higher overall, hematologic, or gastrointestinal toxicity in the patients receiving carboplatin and paclitaxel was 57, 48 and 10%, respectively. No treatment-related deaths were observed. After adjuvant treatment 15 patients developed recurrent disease, 10 of whom had distant metastases. The median recurrence-free survival (RFS was 12.3 months. The median overall survival (OS was 16.0 months. Patients with R0 resection had significantly longer OS than did those with positive surgical margins (log-rank p = 0.0060. Median OS for the R0 resection group was 28.8 months. Conclusions: Carboplatin and paclitaxel added to radiation plus fluoropyrimidine analogs is a well-tolerated regimen in the adjuvant setting. The activity of this regimen

    About a third of patients with ovarian cancer present with localized disease; despite surgical resection, up to half the tumors recur. Since it has not been established whether adjuvant treatment can benefit such patients, we conducted two prospective, randomized national cooperative trials of adjuvant therapy in patients with localized ovarian carcinoma. All patients underwent surgical resection plus comprehensive staging and, 18 months later, surgical re-exploration. In the first trial, 81 patients with well-differentiated or moderately well differentiated cancers confined to the ovaries (Stages Iai and Ibi) were assigned to receive either no chemotherapy or melphalan (0.2 mg per kilogram of body weight per day for five days, repeated every four to six weeks for up to 12 cycles). After a median follow-up of more than six years, there were no significant differences between the patients given no chemotherapy and those treated with melphalan with respect to either five-year disease-free survival or overall survival. In the second trial, 141 patients with poorly differentiated Stage I tumors or with cancer outside the ovaries but limited to the pelvis (Stage II) were randomly assigned to treatment with either melphalan (in the same regimen as above) or a single intraperitoneal dose of 32P (15 mCi) at the time of surgery. In this trial (median follow-up, greater than 6 years) the outcomes for the two treatment groups were similar with respect to five-year disease-free survival (80 percent in both groups) and overall survival (81 percent with melphalan vs. 78 percent with 32P; P = 0.48). We conclude that in patients with localized ovarian cancer, comprehensive staging at the time of surgical resection can serve to identify those patients (as defined by the first trial) who can be followed without adjuvant chemotherapy

    Purpose: To identify the prognostic role of adjuvant abdominal radiation therapy (RT) on oncologic outcomes as a part of multimodal treatment in the management of desmoplastic small round cell tumor (DSRCT) and to determine its impact according to the quality of surgical resection. Methods and Materials: All patients treated for primary abdominal DSRCT in 8 French centers from 1991 to 2014 were included. Patients were retrospectively staged into 3 groups: group A treated with adjuvant RT after cytoreductive surgery, group B without RT after cytoreductive surgery, and group C by exclusive chemotherapy. Peritoneal progression-free survival (PPFS), progression-free survival (PFS), and overall survival (OS) were evaluated. We also performed a direct comparison between groups A and B to evaluate RT after cytoreductive surgery. Radiation therapy was also evaluated according to completeness of surgery: complete cytoreductive surgery (CCS) or incomplete cytoreductive surgery (ICS). Results: Thirty-seven (35.9%), thirty-six (34.9%), and thirty (28.0%) patients were included in groups A, B, and C, respectively. Three-year OS was 61.2% (range, 41.0%-76.0%), 37.6% (22.0%-53.1%), and 17.3% (6.3%-32.8%) for groups A, B, and C, respectively. Overall survival, PPFS, and PFS differed significantly among the 3 groups (P<.001, P<.001, and P<.001, respectively). Overall survival and PPFS were higher in group A (RT group) compared with group B (no RT group) (P=.045 and P=.006, respectively). Three-year PPFS was 23.8% (10.3%-40.4%) for group A and 12.51% (4.0%-26.2%) for group B. After CCS, RT improved PPFS (P=.024), but differences in OS and PFS were not significant (P=.40 and P=.30, respectively). After ICS, RT improved OS (P=.044). A trend of PPFS and PFS increase was observed, but the difference was not statistically significant (P=.073 and P=.076). Conclusions: Adjuvant RT as part of multimodal treatment seems to confer oncologic benefits for patients treated for abdominal DSRCT

    Full Text Available Disinfectant and antibacterial properties of ozone are utilized in the treatment of nonhealing or ischemic wounds. We present here a case of 59 years old woman with compartment syndrome following surgical treatment of stress fracture of proximal tibia with extensively infected wound and exposed tibia to about 4/5 of its extent. The knee joint was also infected with active pus draining from a medial wound. At presentation the patient had already taken treatment for 15 days in the form of repeated wound debridements and parenteral antibiotics, which failed to heal the wound and she was advised amputation. Topical ozone therapy twice daily and ozone autohemotherapy once daily were given to the patient along with daily dressings and parenteral antibiotics. Within 5 days, the wound was healthy enough for spilt thickness skin graft to provide biological dressing to the exposed tibia bone. Topical ozone therapy was continued for further 5 days till the knee wound healed. On the 15th day, implant removal, intramedullary nailing, and latissimus dorsi pedicle flap were performed. Both the bone and the soft tissue healed without further complications and at 20 months follow-up, the patient was walking independently with minimal disability.

    Purpose: Adjuvant radiotherapy (RT) is often considered for endometrial cancer. We studied the effect of RT and surgical treatment on patients' quality of life (QOL). Methods and Materials: All patients referred to the gynecologic oncology clinics with biopsy findings showing endometrial cancer were recruited. QOL assessments were performed using the European Organization for Research and Treatment of Cancer QOL questionnaire-C30, version 3. Assessments were obtained at study entry and at regular 3-month intervals for a maximum of 2 years. Open-ended telephone interviews were done every 6 months. Linear mixed regression models were built using QOL domain scores as dependent variables, with the predictors of surgical treatment and adjuvant RT type. Results: A total of 40 patients were recruited; 80% of the surgeries were performed by laparotomy. Significant improvements were seen in most QOL domains with increased time from treatment. Adjuvant RT resulted in significantly more severe bowel symptoms and improvement in insomnia compared with conservative follow-up. No significant adverse effect from adjuvant RT was seen on the overall QOL. Bowel symptoms were significantly increased in patients treated with laparotomy compared with laparoscopy in the patients treated with whole pelvic RT. Qualitatively, about one-half of the patients noted improvements in their overall QOL during follow-up, with easy fatigability the most prevalent. Conclusion: No significant adverse effect was seen on patients' overall QOL with adjuvant pelvic RT after the recovery period. The acute adverse effects on patients' QOL significantly improved with an increasing interval from diagnosis.

    2011-02-01

    Following surgery for early breast cancer, the standard of care for postmenopausal women is adjuvant therapy with any combination of radiation therapy, endocrine therapy, chemotherapy and/or targeted therapy. Clinicians rely on many tools, including guidelines, to make these treatment decisions. Such guidelines include the St Gallen consensus statement, the American Society of Clinical Oncology guidelines and the National Comprehensive Cancer Network guidelines, as well as various regional and national guidelines. Recommendations may vary, because different methods and criteria were used to assess the strength of supporting data. This article provides an overview of global guidelines for the adjuvant treatment of breast cancer and points out the major differences. Ongoing changes are highlighted, particularly those regarding the adjuvant endocrine treatment of postmenopausal women with breast cancer. While previous guidelines recommended tamoxifen alone, all major guidelines now recommend using third-generation aromatase inhibitors either in sequence with tamoxifen or as upfront treatment.

    interval, 1.22-11.63) than expected. The median duration for developing a second cancer was 11 years for tumors arising from tissues outside the irradiated field and 14 years for those within or near the irradiated area. Conclusions: The overall observed incidence of second nontesticular malignancy among patients with early-stage testicular seminoma treated with adjuvant radiation therapy was not significantly increased in comparison with the expected incidence. Clinical implications are discussed.

    Purpose: This study was performed to evaluate the outcome of patients with gallbladder cancer who received postoperative concurrent chemotherapy and radiation therapy. Methods and Materials: Curative resection followed by adjuvant combined modality therapy with external beam radiation therapy (EBRT) and chemotherapy was attempted in 21 consecutive gallbladder carcinoma (GBC) patients at the Mayo Clinic from 1985 through 1997. All patients received concurrent 5-fluorouracil during EBRT. EBRT fields encompassed the tumor bed and regional lymph nodes (median dose of 54 Gy in 1.8-2.0-Gy fractions). One patient received 15 Gy intraoperatively after EBRT. A retrospective analysis was performed for the end points of local control, distant failure, and overall survival. Results: After maximal resection, 12 patients had no residual disease on pathologic evaluation, 5 had microscopic residual disease, and 4 had gross residual disease. One patient had Stage I disease, and 20 had Stage III-IV disease. With median follow-up of 5 years (range: 2.6-11.5 years), 5-year survival for the entire cohort was 33%. The 5-year survival rate of patients with Stage I-III disease was 65% vs. 0% for those with Stage IV disease (p 54 Gy (microscopic residual, 3 patients; gross residual, 1 patient; negative but narrow margins, 2 patients) vs. 65% for the 15 who received a lower dose (3, gross residual; 2, microresidual; 10, negative margins). Conclusion: Patients with completely resected (negative margins) GBC followed by adjuvant EBRT plus 5-fluorouracil chemotherapy had a relatively favorable prognosis, with a 5-year survival rate of 64%. These results seem to be superior to historical surgical controls from the Mayo Clinic and other institutions, which report 5-year survival rates of approximately 33% with complete resection alone. Both tumor stage and extent of resection seemed to influence survival and local control. More aggressive measures using current cancer therapies and integration

    The objective of this review is to evaluate the evidence regarding the use of music as an adjuvant therapy for pain control in hospitalized adults. The search terms music, music therapy, pain, adults, inpatient, and hospitalized were used to search the Cochrane Library, Cinahl, Medline, Natural Standard, and Scopus databases from January 2005 to March 2011. (A systematic review conducted by the Cochrane Collaboration has extensively covered the time frame from 1966 to 2004.) Seventeen randomized controlled trials met criteria for review and inclusion. Seven of the research studies were conducted with surgical patients, three with medical patients, one with medical-surgical patients, four with intensive care patients, and two with pregnant patients. The combined findings of these studies provide support for the use of music as an adjuvant approach to pain control in hospitalized adults. The use of music is safe, inexpensive, and an independent nursing function that can be easily incorporated into the routine care of patients.

    Purpose: To evaluate the efficacy of adjuvant chemoradiation therapy (CRT) for pancreatic adenocarcinoma patients ≥75 years of age. Methods: The study group of 655 patients underwent pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma at the Johns Hopkins Hospital over a 12-year period (8/30/1993 to 2/28/2005). Demographic characteristics, comorbidities, intraoperative data, pathology data, and patient outcomes were collected and analyzed by adjuvant treatment status and age ≥75 years. Cox proportional hazards analysis determined clinical predictors of mortality and morbidity. Results: We identified 166 of 655 (25.3%) patients were ≥75 years of age and 489 of 655 patients (74.7%) were <75 years of age. Forty-nine patients in the elderly group (29.5%) received adjuvant CRT. For elderly patients, node-positive metastases (p = 0.008), poor/anaplastic differentiation (p = 0.012), and undergoing a total pancreatectomy (p = 0.010) predicted poor survival. The 2-year survival for elderly patients receiving adjuvant therapy was improved compared with surgery alone (49.0% vs. 31.6%, p = 0.013); however, 5-year survival was similar (11.7% vs. 19.8%, respectively, p = 0.310). After adjusting for major confounders, adjuvant therapy in elderly patients had a protective effect with respect to 2-year survival (relative risk [RR] 0.58, p = 0.044), but not 5-year survival (RR 0.80, p = 0.258). Among the nonelderly, CRT was significantly associated with 2-year survival (RR 0.60, p < 0.001) and 5-year survival (RR 0.69, p < 0.001), after adjusting for confounders. Conclusions: Adjuvant therapy after PD is significantly associated with increased 2-year but not 5-year survival in elderly patients. Additional studies are needed to select which elderly patients are likely to benefit from adjuvant CRT.

    This study was undertaken to evaluate the efficacy of postoperative radiotherapy, and to investigate the prognostic factors for FIGO stages IB-IIB cervical cancer patients who were treated with simple hysterectomy, or who had high-risk factors following radical hysterectomy and pelvic lymph node dissection. Between March 1986 and December 1998, 58 patients, with FIGO stages IB-IIB cervical cancer were included in this study, The indications for postoperative radiation therapy were based on the pathological findings, including lymph node metastasis, positive surgical margin, parametrial extension, Iymphovascular invasion, invasion of more than half the cervical stroma, uterine extension and the incidental finding of cervix cancer following simple hysterectomy. All patients received external pelvic radiotherapy, and 5 patients, received an additional intracavitary radiation therapy. The radiation dose from the external beam to the whole pelvis was 45 - 50 Gy. Vagina cuff irradiation was performed, after completion of the external beam irradiation, al a low-dose rate of CS-137, with the total dose of 4488-4932 chy (median: 4500 chy) at 5 mm depth from the vagina surface. The median follow-up period was 44 months (15-108 months), The 5-yr actuarial local control rate, distant free survival and disease-free survival rate were 98%, 95% and 94%, respectively. A univariate analysis of the clinical and pathological parameters revealed that the clinical stage (p=0.0145), status of vaginal resection margin (p=0.0002) and parametrial extension (p=0.0001) affected the disease-free survival. From a multivariate analysis, only a parametrial extension independently influenced the disease-free survival. Five patients (9%) experienced Grade 2 late treatment-related complications, such as radiation proctitis (1 patient), cystitis (3 patients) and lymphedema of the leg (1 patient). No patient had grade 3 or 4 complications. Our results indicate that postoperative radiation therapy can

    Adjuvant breast radiation therapy after breast conservation surgery is recommended as it yields significant reduction in the risk of local recurrence, and confers a potential overall survival benefit. Although the standard breast radiation regimen has historically been delivered over 57 weeks; more novel, shorter courses of breast radiation are currently being employed, offering the advantage of more convenience and less time-commitment. Herein, we review the recent literature substantiating these abbreviated radiation treatment approaches and the methods of delivery thereof. In addition, we discuss imaged guided techniques currently being utilized to further refine the delivery of adjuvant breast radiation therapy

    It is known that there is a significant interplay of insulin resistance, oxidative stress, dyslipidemia, and inflammation in type 2 diabetes mellitus (T2DM). The study was undertaken to investigate the effect of turmeric as an adjuvant to anti-diabetic therapy. Sixty diabetic subjects on metformin therapy were recruited and randomized into two groups (30 each). Group I received standard metformin treatment while group II was on standard metformin therapy with turmeric (2 g) supplements for 4 ...

    Background: We studied whether hormonal therapy, (neo)adjuvant to radiotherapy for localized prostate cancer, is related to an increase in depression and whether this is caused by the hormonal therapy itself or by the relatively poor prognosis of patients who get (neo)adjuvant hormonal therapy. Methods: Between 2002 and 2005, 288 patients, irradiated for prostate cancer (T1-3N0M0), were studied prospectively in two clinics. In one clinic almost all patients received (neo)adjuvant androgen deprivation (Bicalutamide + Gosereline). In a second clinic hormonal therapy was prescribed mainly for high risk patients. This allowed us to separate the effects of hormonal therapy and the patient's prognosis. Results: During the course of hormonal therapy, depression was significantly heightened by both hormone use (p < 0.001) and poor prognosis (p < 0.01). After completion of hormonal therapy, poor prognosis continued to affect the depression score (p < 0.01). The increase was, however, small. Conclusions: Depression was mildly increased in patients receiving hormonal therapy. The increase appeared to be related to both the hormone therapy itself and the high risk status of patients. High risk status, with the associated poor prognosis, had a more sustained effect on depression. The rise was statistically significant, but was too small, however, to bear clinical significance.

    To compare simple conventional treatment with the addition of hyperbaric oxygen therapy (HBOT) to conventional therapies in the treatment of Fournier's gangrene (FG). A retrospective study of clinical data was performed by reviewing 28 cases of FG from January 2004 to December 2013 at Xiangya Hospital, Central South University. Among them, 12 patients were treated with the conventional therapy (non-HBOT group) and the other 16 cases were combined with hyperbaric oxygen therapy besides conventional therapy (HBOT group). All patients were followed up for 2 months to assess the therapeutic effect. The analyzed data included age, Fournier gangrene severity index (FGSI) score, number of surgical debridement, indwelling drainage tube time, length of stay (LOS), effective time, and curative time. The mortality rate was lower in the HBOT group at 12.5% (2/16) compared to the non-HBOT group, which was 33.3% (4/12). The difference in the number of surgical debridement, indwelling drainage tube time, and curative time between were significantly lower in the HBOT group compared to the non-HBOT group. Our preliminary research suggests that the effect of combining hyperbaric oxygen therapy with conventional therapy offers considerable advantage in the management of Fournier's gangrene. Multicenter studies with a larger sample size are required to confirm these observations. © 2015 S. Karger AG, Basel.

    In recent years, nonsteroidal anti-inflammatory drugs have been found to be cogent as an adjuvant therapeutic agent in mitigating colorectal cancer. Thus, this present investigation was aimed to formulate an oral, targeted tablet of piroxicam microspheres for sustained and targeted adjuvant therapy for colonic adenocarcinomas. Crosslinked guar gum microspheres of piroxicam were directly compressed into matrix tablet and coated with Eudragit S100. The optimized tablet that displayed 0% release in simulated gastric fluid, 15% in simulated intestinal fluid and 97.1% in simulated colonic fluid underwent roentgenographic study in rabbits to check its safe transit to the colon. x-ray images revealed intactness of the tablet until it reached the colon where the tablet matrix eroded. The designed, conceptual formulation emerged as potential carrier for targeted adjuvant therapy of piroxicam.

    Purpose: Prolonged radiation therapy treatment time (RTT) is associated with worse survival in several tumor types. This study investigated whether delays during adjuvant radiation therapy impact overall survival (OS) in gastric cancer. Methods and Materials: The National Cancer Data Base was queried for patients with resected gastric cancer who received adjuvant radiation therapy with National Comprehensive Cancer Network–recommended doses (45 or 50.4 Gy) between 1998 and 2006. RTT was classified as standard (45 Gy: 33-36 days, 50.4 Gy: 38-41 days) or prolonged (45 Gy: >36 days, 50.4 Gy: >41 days). Cox proportional hazards models evaluated the association between the following factors and OS: RTT, interval from surgery to radiation therapy initiation, interval from surgery to radiation therapy completion, radiation therapy dose, demographic/pathologic and operative factors, and other elements of adjuvant multimodality therapy. Results: Of 1591 patients, RTT was delayed in 732 (46%). Factors associated with prolonged RTT were non-private health insurance (OR 1.3, P=.005) and treatment at non-academic facilities (OR 1.2, P=.045). Median OS and 5-year actuarial survival were significantly worse in patients with prolonged RTT compared with standard RTT (36 vs 51 months, P=.001; 39 vs 47%, P=.005); OS worsened with each cumulative week of delay (P<.0004). On multivariable analysis, prolonged RTT was associated with inferior OS (hazard ratio 1.2, P=.002); the intervals from surgery to radiation therapy initiation or completion were not. Prolonged RTT was particularly detrimental in patients with node positivity, inadequate nodal staging (<15 nodes examined), and those undergoing a cycle of chemotherapy before chemoradiation therapy. Conclusions: Delays during adjuvant radiation therapy appear to negatively impact survival in gastric cancer. Efforts to minimize cumulative interruptions to <7 days should be considered

    Cancer stem cells (CSCs) are notorious for their capacity of tumor progression, metastasis or resistance to chemo-radiotherapy. However, the undisputed role of cancer stem marker, CD133, in colorectal cancers (CRCs) is not clear yet. We assessed 271 surgically-resected stage II and III primary CRCs with (171) and without (100) adjuvant therapy after surgery. CD133 expression was analyzed by immunohistochemical (IHC) staining and real-time RT-PCR. CD133 promoter methylation was quantified by pyrosequencing. The CD133 IHC expression was significantly correlated with mRNA expression (p=0.0257) and inversely correlated with the promoter methylation (p=0.0001). CD133 was expressed more frequently in rectal cancer (p=0.0035), and in moderately differentiated tumors (p=0.0378). In survival analysis, CD133 expression was not significantly correlated with overall survival (OS) (p=0.9689) as well as disease-free survival (DFS) (p=0.2103). However, CD133+ tumors were significantly associated with better OS in patients with adjuvant therapy compared to those without adjuvant therapy (p<0.0001, HR 0.125, 95% CI 0.052-0.299). But the patients with CD133- tumors did not show any significant difference of survival according to adjuvant therapy (p=0.055, HR 0.500, 95% CI 0.247-1.015). In stage II and III CRCs, CD133 IHC expression may signify the benefit for adjuvant therapy although it is not an independent prognostic factor

    There is no universally agreed policy for treating keloid scars of the ear lobe following piercing. We treated 35 patients (34 women) for high-risk ear-lobe keloids; the average age was 24 years (range: 16-44 years). All had failed to respond to prior treatment with massage and silicone, and corticosteroid injection. The keloids were excised extralesionally and the defects were closed with interrupted prolene sutures. The operative scar was covered with topical 2% lignocaine-0.25% chlorhexidine sterile lubricant gel under a transparent adhesive dressing. Adjuvant postoperative radiotherapy of 10 Gy, applied as 100 kV photons (4 mm high-voltage therapy (HVT) Al), was given within 24 h of surgery. All keloid scars were controlled at 4 weeks' follow-up. At 1 year, three out of 34 cases followed up had relapsed (probability of control: 91.2%). At 5 years, a further four out of the remaining 31 patients had relapsed (cumulative probability of control at 5 years: 79.4%). There were no cases of serious toxicity.

    Purpose Local recurrence is a common failure pattern in adenocarcinoma of the cecum. This study aimed to investigate the potential role of adjuvant radiation therapy on oncologic outcomes of patients with adenocarcinoma of the cecum. Materials and Methods This retrospective study was carried out at three large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of 162 patients with adenocarcinoma of the cecum that were treated and followed up between 2000 and 2013. All the patients had undergone a right hemicolectomy and received chemotherapy with (n = 48) or without (n = 114) adjuvant radiation therapy. Results The subjects were 65 females and 97 males with a median age of 56 years (range, 17 to 90 years) at diagnosis. The 5-year local control (LC), disease free survival (DFS), and overall survival (OS) rates were 72.7%, 57.2%, and 62.6% respectively. In a multivariate analysis, age, tumor stage, node stage, and adjuvant radiation therapy were determined to be independent prognostic factors. Age more than 55 years (hazard ratio [HR] = 1.0; 95% confidence interval [CI], 0.06–0.32; p = 0.003], T4 stage (HR = 6.8; 95% CI, 3.07–15.36; p < 0.001), node positive disease (HR = 4.2; 95% CI, 1.94–9.13; p < 0.001), and the absence of adjuvant radiation therapy (HR = 3.0; 95% CI, 1.39–6.46; p = 0.005) had a negative influence on OS. Conclusion Adjuvant radiation therapy significantly improves DFS and OS in patients with adenocarcinoma of the cecum. PMID:29506326

    Dendritic cell-based (DC-based) vaccines are promising immunotherapies for cancer. However, several factors, such as the lack of efficient targeted delivery and the sources and types of DCs, have limited the efficacy of DCs and their clinical potential. We propose an alternative nanotechnology-based vaccine platform with antibacterial prophylactic abilities that uses gold glyconanoparticles coupled to listeriolysin O 91-99 peptide (GNP-LLO 91-99 ), which acts as a novel adjuvant for cancer therapy. GNP-LLO 91-99 , when used to vaccinate mice, exhibited dual antitumour activities, namely, the inhibition of tumour migration and growth and adjuvant activity for recruiting and activating DCs, including those from melanoma patients. GNP-LLO 91-99 nanoparticles caused tumour apoptosis and induced antigen- and melanoma-specific cytotoxic Th1 responses (P ≤ 0.5). We propose this adjuvant nanotherapy for preventing the progression of the first stages of melanoma.

    Full Text Available Calreticulin is recognized as one of pivotal damage-associated molecular pattern (DAMP molecules alerting the host of the presence of distressed cells. In this role, calreticulin becomes exposed on the surface of tumor cells treated by several types of cancer therapy including photodynamic therapy (PDT. The goal of the present study was to examine the potential of externally added calreticulin for augmenting antitumor effect mediated by PDT. Recombinant calreticulin was found to bind to mouse SCCVII tumor cells treated by PDT. Compared to the outcome with PDT alone, cure-rates of SCCVII tumors grown in immunocompetent C3H/HeN mice were elevated when calreticulin (0.4 mg/mouse was injected peritumorally immediately after PDT. Such therapeutic gain with PDT plus calreticulin combination was not obtained with SCCVII tumors growing in immunodeficient NOD-scid mice. In PDT vaccine protocol, where PDT-treated SCCVII cells are used for vaccination of SCCVII tumor-bearing mice, adding recombinant calreticulin to cells before their injection produced improved therapeutic effect. The expression of calreticulin gene was reduced in PDT-treated cells, while no changes were observed with the expression of this gene in tumor, liver, and spleen tissues in PDT vaccine-treated mice. These findings reveal that externally added recombinant calreticulin can boost antitumor responses elicited by PDT or PDT-generated vaccines, and can thus serve as an effective adjuvant for cancer treatment with PDT and probably other cancer cell stress-inducing modalities.

    Purpose: The criteria for administration of adjuvant radiation therapy (RT) in oral cavity squamous cell carcinoma (OSCC) remain controversial, and it is unclear whether patients with pT1-3N0 disease benefit from adjuvant radiation in the presence of free margins and perineural invasion. The goal of this report was to determine whether this group would benefit from adjuvant radiation therapy in terms of 5-year local control rate and overall survival rate. Methods and Materials: We retrospectively reviewed our case records from January 1996 to May 2005. In all, 460 pT1-3N0 OSCC patients had tumor-free margins, of whom 68 had perineural invasion. Postoperative adjuvant RT was performed in patients with pT4 tumors, positive lymph nodes, or close margins (≤4 mm). In addition, selected OSCC patients with large pT3 tumors or perineural invasion received postoperative adjuvant RT. Local control and overall survival rates were plotted by Kaplan-Meier analysis. Results: There were no significant differences in 5-year local control (p 0.1936) and overall survival (p = 0.5580) rates between patients with perineural invasion compared with those without. Among patients with perineural invasion, the addition of adjuvant radiotherapy did not significantly alter the 5-year local control rate (p = 0.3170) or the overall survival rate (p = 0.0935). Conclusion: Altogether, these data seem to indicate that radical surgical resection alone should be considered a sufficient treatment for OSCC patients with pT1-3N0 disease, even in the presence of perineural invasion

    Purpose: To evaluate actuarial rates of local failure in patients with pathologic N1 non–small-cell lung cancer and to identify clinical and pathologic factors associated with an increased risk of local failure after resection. Methods and Materials: All patients who underwent surgery for non–small-cell lung cancer with pathologically confirmed N1 disease at Duke University Medical Center from 1995–2008 were identified. Patients receiving any preoperative therapy or postoperative radiotherapy or with positive surgical margins were excluded. Local failure was defined as disease recurrence within the ipsilateral hilum, mediastinum, or bronchial stump/staple line. Actuarial rates of local failure were calculated with the Kaplan-Meier method. A Cox multivariate analysis was used to identify factors independently associated with a higher risk of local recurrence. Results: Among 1,559 patients who underwent surgery during the time interval, 198 met the inclusion criteria. Of these patients, 50 (25%) received adjuvant chemotherapy. Actuarial (5-year) rates of local failure, distant failure, and overall survival were 40%, 55%, and 33%, respectively. On multivariate analysis, factors associated with an increased risk of local failure included a video-assisted thoracoscopic surgery approach (hazard ratio [HR], 2.5; p = 0.01), visceral pleural invasion (HR, 2.1; p = 0.04), and increasing number of positive N1 lymph nodes (HR, 1.3 per involved lymph node; p = 0.02). Chemotherapy was associated with a trend toward decreased risk of local failure that was not statistically significant (HR, 0.61; p = 0.2). Conclusions: Actuarial rates of local failure in pN1 disease are high. Further investigation of conformal postoperative radiotherapy may be warranted.

    Uterine serous carcinoma (USC) is an aggressive type 2 endometrial cancer. Data on prognostic factors for patients with early-stage USC without adjuvant therapy are limited. This study aims to assess the baseline recurrence risk of early-stage USC patients without adjuvant treatment and to identify prognostic factors and patients who need adjuvant therapy. Sixty-eight patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II USC between 1997 and 2016 were included. All the cases did not undergo adjuvant treatment as institutional practice. Clinicopathological features, recurrence patterns, and survival outcomes were analyzed to determine prognostic factors. FIGO stages IA, IB, and II were observed in 42, 7, and 19 cases, respectively. Median follow-up time was 60 months. Five-year disease-free survival (DFS) and overall survival (OS) rates for all cases were 73.9% and 78.0%, respectively. On multivariate analysis, cervical stromal involvement and positive pelvic cytology were significant predictors of DFS and OS, and ≥1/2 myometrial invasion was also a significant predictor of OS. Of 68 patients, 38 patients had no cervical stromal invasion or positive pelvic cytology and showed 88.8% 5-year DFS and 93.6% 5-year OS. Cervical stromal invasion and positive pelvic cytology are prognostic factors for stage I-II USC. Patients with stage IA or IB USC showing negative pelvic cytology may have an extremely favorable prognosis and need not receive any adjuvant therapies. Copyright © 2018.

    Purpose: To compare the survival impact of adjuvant external beam radiation therapy (RT) for malignant gliomas of glioblastoma (GBM), anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), and mixed anaplastic oligoastrocytoma (AOA) histology. Methods and Materials: The Surveillance, Epidemiology, and End Results (SEER) database was queried from 1998 to 2007 for patients aged ≥18 years with high-grade gliomas managed with upfront surgical resection, treated with and without adjuvant RT. Results: The primary analysis totaled 14,461 patients, with 12,115 cases of GBM (83.8%), 1312 AA (9.1%), 718 AO (4.9%), and 316 AOA (2.2%). On univariate analyses, adjuvant RT was associated with significantly improved overall survival (OS) for GBMs (2-year OS, 17% vs 7%, p<.001), AAs (5-year OS, 38% vs 24%, p<.001), and AOAs (5-year OS, 55% vs 44%, p=.026). No significant differences in OS were observed for AOs (5-year OS, with RT 50% vs 56% without RT, p=.277). In multivariate Cox proportional hazards models accounting for extent of resection, age, sex, race, year, marital status, and tumor registry, RT was associated with significantly improved OS for both GBMs (HR, 0.52; 95% CI, 0.50-0.55; P<.001) and AAs (HR, 0.57; 95% CI, 0.48-0.68; P<.001) but only a trend toward improved OS for AOAs (HR, 0.70; 95% CI, 0.45-1.09; P=.110). Due to the observation of nonproportional hazards, Cox regressions were not performed for AOs. A significant interaction was observed between the survival impact of RT and histology overall (interaction P<.001) and in a model limited to the anaplastic (WHO grade 3) histologies. (interaction P=.024), characterizing histology as a significant predictive factor for the impact of RT. Subgroup analyses demonstrated greater hazard reductions with RT among patients older than median age for both GBMs and AAs (all interaction P≤.001). No significant interactions were observed between RT and extent of resection. Identical patterns of significance were

    To study the effect of adjuvant lithium on serum thyroxine (T4) concentrations in patients treated with radioactive iodine (RAI) therapy in our environment. This was a prospective simple randomized comparative, experimental cohort study of patients with hyperthyroidism referred for RAI ablation therapy in the two main academic hospitals in Johannesburg between February 2014 and September 2015. Amongst the 163 participants in the final analysis, 75 received RAI alone and 88 received RAI with lithium. The difference in mean T4 concentrations at 3 months between the RAI-only group (17.67 pmol/l) and the RAI with lithium group (11.55 pmol/l) was significant with a small effect size (U = 2328.5, Z = -2.700, p = 0.007, r = 0.01). Significant decreases in T4 concentrations were observed as early as 1 month after RAI (p = 0.0001) in the RAI with lithium group, but in the RAI-only group, significant decreases in T4 concentrations were observed only at 3 months after RAI therapy (p = 0.000). Women and patients with Graves' disease who received RAI with adjuvant lithium also showed significant decreases in T4 concentrations at 1 month (p = 0.002 and p = 0.003, respectively). Adjuvant lithium leads to an earlier and better response to RAI therapy with lower T4 concentrations that are achieved earlier. This earlier response and decrease in T4 concentrations were noted in patients with Graves' disease and nodular goitre, and in women with hyperthyroidism who received adjuvant lithium therapy.

    2017-06-01

    Full Text Available Thymoquinone (TQ, the main bioactive component of Nigella sativa, has been found to exhibit anticancer effects in numerous preclinical studies. Due to its multitargeting nature, TQ interferes in a wide range of tumorigenic processes and counteracts carcinogenesis, malignant growth, invasion, migration, and angiogenesis. Moreover, TQ can specifically sensitize tumor cells toward conventional cancer treatments (e.g., radiotherapy, chemotherapy, and immunotherapy and simultaneously minimize therapy-associated toxic effects in normal cells. In this review, we summarized the adjuvant potential of TQ as observed in various in vitro and in vivo animal models and discussed the pharmacological properties of TQ to rationalize its supplementary role in potentiating the efficacy of standard therapeutic modalities namely surgery, radiotherapy, chemotherapy, and immunotherapy. Altogether, we suggest further comprehensive evaluation of TQ in preclinical and clinical levels to delineate its implied utility as a novel complementary adjuvant therapy for cancer treatment.

    Vacuum-assisted closure (VAC) therapy is a new emerging non-invasive system in wound care, which speeds up wound healing by causing vacuum, improving tissue perfusion and suctioning the exudates, and facilitating the removal of bacteria from the wound. The application of sub-atmospheric pressure on the lesions seems to alter the cytoskeleton of the cells on the wound bed, triggering a cascade of intracellular signals that increase the rate of cell division and subsequent formation of granulation tissue. The aim of this study is to analyse the results of VAC therapy used as an adjuvant therapy for the treatment of foot wounds in patients affected by critical limb ischaemia (CLI) (Rutherford 6 class) after distal surgical revascularisation, to promote and accelerate the healing of ulcers. Twenty-nine patients (20 males, 9 females; mean age 68·4) affected by CLI of Rutherford 6 class, after surgical revascularisation of the lower limb, underwent VAC therapy in order to speed up wound healing. Complete wound healing was achieved in 19 patients (65·51%), in an average period of 45·4 ± 25·6 days. VAC therapy is a valid aid, after surgical revascularisation, to achieve rapid healing of foot lesions in patients with CLI. © 2014 The Authors.

    To determine if outpatient medications taken at the time of liver tumor embolization or ablation affect survival. A retrospective review was done of 2,032 liver tumor embolization, radioembolization, and ablation procedures performed in 1,092 patients from June 2009 to April 2016. Pathology, hepatocellular carcinoma (HCC) stage (American Joint Committee on Cancer), neuroendocrine tumor (NET) grade, initial locoregional therapy, overall survival after initial locoregional therapy, Child-Pugh score, Eastern Cooperative Oncology Group performance status, Charlson Comorbidity Index, and outpatient medications taken at the time of locoregional therapy were analyzed for each patient. Kaplan-Meier survival curves were calculated for patients taking 29 medications or medication classes (including prescription and nonprescription medications) for reasons unrelated to their primary cancer diagnosis. Kaplan-Meier curves were compared using the log-rank test. For patients with HCC initially treated with embolization (n = 304 patients), the following medications were associated with improved survival when taken at the time of embolization: beta-blockers (P = .0007), aspirin (P = .0008) and other nonsteroidal antiinflammatory drugs (P = .009), proton pump inhibitors (P = .004), and antivirals for hepatitis B or C (P = .01). For colorectal liver metastases initially treated with ablation (n = 172 patients), beta-blockers were associated with improved survival when taken at the time of ablation (P = .02). Aspirin and beta-blockers are associated with significantly improved survival when taken at the time of embolization for HCC. Aspirin was not associated with survival differences after locoregional therapy for NET or colorectal liver metastases, suggesting an HCC-specific effect. Copyright © 2017 SIR.

    1982-01-01

    Bilateral lung irradiation as well as chemotherapy are still controversial in the ''prevention'' of pulmonary metastases from osteosarcomas. This paper presents theoretical and experimental evidence in support of such an irradiation. Doses which can be tolerated by the normal lung are recalled. Data from clinical experience is analyzed and the optimal modalities of irradiation are described. Confirmation of the presumptive effectiveness of radiation therapy can be obtained only through controlled trials such as the one which is ongoing at the EORTC [fr

    The potential of a perfluorochemical emulsion which as an excellent carrying capacity for oxygen to enhance the ability of radiation therapy to delay the growth of Lewis lung tumor was examined. There was a highly significant effect produced by the addition of perfluorochemical emulsion and carbogen breathing in combination with irradiation. With single dose x-ray treatment the dose of perfluorochemical emulsion was varied from 0.05-0.6 ml addition to the blood volume of the animals. The dose response effect was very broad peaking at 0.3-0.4 ml which gave a dose modifying effect of 2.8 +- 0.6 with 1000 rad of x-rays. The addition of 0.3 ml of perfluorochemical free annex solution with carbogen breathing produced a small enhancement in tumor growth delay addition of the same volume of the complete emulsion increased the tumor growth delay time about 3-fold compared to the annex solution. When the perfluorochemical emulsion was added to a fractionated course of radiation therapy a dose modifying effect of 1.8 +- 0.3 was obtained. Oxygen carrying perfluorochemical emulsions may provide a nontoxic clinically useful means of increasing the effectiveness of radiation therapy and of certain chemotherapeutic agents

    Full Text Available Summary:. Most cases of severely contracted nose require revision rhinoplasty and septoplasty, wherein preoperative and/or intraoperative expansion of nasal soft tissue is necessary for tension-free revision surgery. The present study aimed to evaluate the efficacy and safety of pre- and postoperative adjuvant therapy using polydeoxyribonucleotide (PDRN and invasive, pulsed-type, bipolar, alternating current radiofrequency (RF for revision surgery of a contracted nose. In total, 30 patients were treated with 16 sessions (8 preoperative sessions and 8 postoperative sessions of intralesional injection of PDRN and invasive RF treatment using microneedle electrodes at 1-week intervals. One week after the final combined pretreatment using PDRN and invasive bipolar RF, the skin of contracted noses was sufficiently softened, and nasal skin mobility was notably improved in all the patients. During revision rhinoplasty and septoplasty, the contracted nasal skin in each patient was adequately released for proper covering of the nasal tip without tension. Postoperatively, 8 sessions of adjuvant therapy elicited marked clinical improvements in persistent nasal tip dimpling and contracture, septal deviation, and warping from the incomplete recovery of nasal contracture after revision surgery. In conclusion, our pre- and postoperative adjuvant therapies using PDRN and invasive bipolar RF remarkably improved the therapeutic outcomes of revision rhinoplasty and septoplasty for contracted skin of the nose without major side effects.

    Melanoma incidence and mortality rates are rising in Italy, indicating that more effective treatments are required both in the adjuvant and metastatic settings. We analyzed clinical practices in the adjuvant and metastatic settings by conducting a nationwide survey of clinicians responsible for managing melanoma treatment and follow-up in a representative sample of Italian hospitals. 95% of participating hospitals completed the panel of questions on adjuvant and metastatic treatment, making it likely that these results give a realistic picture of treatment and follow-up of melanoma patients in Italy. In low-volume hospitals (<25 new melanoma diagnoses yearly) adjuvant therapy was significantly more used than in large-volume hospitals for patients in stage III and IV (82 versus 66% and 56 versus 30%, respectively), and only 11% of patients were enrolled in clinical trials. In the metastatic setting dacarbazine was the preferred first-line treatment (32%) followed by polychemotherapy (23%); 12% of patients were enrolled in clinical trials and less than 10% received interleukin-2, usually subcutaneously. The information provided by this study was used by the Italian Melanoma Intergroup to improve the quality of care and to redirect financial resources. Copyright © 2013 S. Karger AG, Basel.

    Full Text Available Purpose. Although randomized trials suggest a survival benefit of adjuvant chemotherapy and radiation therapy (XRT for gastric adenocarcinoma, its use in patients who undergo an extended lymphadenectomy is less clear. The purpose of this study was to determine if a survival benefit exists in gastric cancer patients who receive adjuvant XRT following resection with extended lymphadenectomy. Methods. The SEER registry was queried for records of patients with resected gastric adenocarcinoma from 1988 to 2007. Multivariable Cox regression models were used to assess independent prognostic factors affecting overall survival (OS and disease-specific survival (DSS. Results. Of 15,060 patients identified, 3,208 (21% received adjuvant XRT. Adjuvant XRT was independently associated with improved OS (HR 0.67, CI 0.64–0.71 and DSS (HR 0.69, CI 0.65–0.73 in stages IB through IV (M0. This OS and DSS benefit persisted regardless of the extent of lymphadenectomy. Furthermore, lymphadenectomy with >25 LN resected was associated with improved OS and DSS compared with 25 LNs results in improved OS and DSS compared with patients who have fewer LNs resected.

    Multidisciplinary team (MDT) meetings are used to optimise expert decision-making about treatment options, but such expertise is not digitally transferable between centres. To help standardise medical decision-making, we developed a machine learning model designed to predict MDT decisions about adjuvant breast cancer treatments. We analysed MDT decisions regarding adjuvant systemic therapy for 1065 breast cancer cases over eight years. Machine learning classifiers with and without bootstrap aggregation were correlated with MDT decisions (recommended, not recommended, or discussable) regarding adjuvant cytotoxic, endocrine and biologic/targeted therapies, then tested for predictability using stratified ten-fold cross-validations. The predictions so derived were duly compared with those based on published (ESMO and NCCN) cancer guidelines. Machine learning more accurately predicted adjuvant chemotherapy MDT decisions than did simple application of guidelines. No differences were found between MDT- vs. ESMO/NCCN- based decisions to prescribe either adjuvant endocrine (97%, p = 0.44/0.74) or biologic/targeted therapies (98%, p = 0.82/0.59). In contrast, significant discrepancies were evident between MDT- and guideline-based decisions to prescribe chemotherapy (87%, p machine learning models. A machine learning approach based on clinicopathologic characteristics can predict MDT decisions about adjuvant breast cancer drug therapies. The discrepancy between MDT- and guideline-based decisions regarding adjuvant chemotherapy implies that certain non-clincopathologic criteria, such as patient preference and resource availability, are factored into clinical decision-making by local experts but not captured by guidelines.

  5. Adjuvant therapy of Dukes' C colon cancer by intra-arterial P-32 colloid for internal radiation therapy of the liver

    1984-09-01

    To prevent probable occult metastatic liver cancer from progressing to clinical disease, the author used internal radiation therapy as an effective adjuvant to surgical excision of primary Dukes' C colonic cancer. A calculated radiation dose of 5000 rads was delivered to the liver by injecting radioactive 32-P chromic phosphate colloid through the superior mesenteric and celiac arteries. When this was done, the colloid passed through the intestines and was mixed thoroughly with the blood and delivered to the liver by the portal vein. The Kupffer cells in the liver trapped the colloid, and a minimum amount passed through the liver and got into the general circulation. This kept the amount of colloid deposited in the bone marrow to a minimum. In a phase-I pilot study in which nine patients were treated, no serious side effects were noted. In eight patients, the liver has remained free of cancer for more than 1 year.

  6. Use of propofol as adjuvant therapy in refractory delirium tremens

    Full Text Available Delirium tremens is recognized as a potentially fatal and debilitating complication of alcohol withdrawal. Use of sedatives, particularly benzodiazepines, is the cornerstone of therapy for delirium tremens. But sometimes, very heavy doses of benzodiazepines are required to control delirious symptoms. We are reporting one such case of delirium tremens, which required very heavy doses of benzodiazepines and was ultimately controlled by using infusion of propofol. Thus propofol should always be considered as an option to treat patients with resistant delirium tremens.

    Purpose To update key recommendations of the ASCO guideline adaptation of the Cancer Care Ontario guideline on the selection of optimal adjuvant chemotherapy regimens for early breast cancer and adjuvant targeted therapy for breast cancer. Methods An Expert Panel conducted targeted systematic literature reviews guided by a signals approach to identify new, potentially practice-changing data that might translate to revised practice recommendations. Results The Expert Panel reviewed phase III trials that evaluated adjuvant capecitabine after completion of standard preoperative anthracycline- and taxane-based combination chemotherapy by patients with early-stage breast cancer HER2-negative breast cancer with residual invasive disease at surgery; the addition of 1 year of adjuvant pertuzumab to combination chemotherapy and trastuzumab for patients with early-stage, HER2-positive breast cancer; and the use of neratinib as extended adjuvant therapy for patients after combination chemotherapy and trastuzumab-based adjuvant therapy with early-stage, HER2-positive breast cancer. Recommendations Patients with early-stage HER2-negative breast cancer with pathologic, invasive residual disease at surgery following standard anthracycline- and taxane-based preoperative therapy may be offered up to six to eight cycles of adjuvant capecitabine. Clinicians may add 1 year of adjuvant pertuzumab to trastuzumab-based combination chemotherapy in patients with high-risk, early-stage, HER2-positive breast cancer. Clinicians may use extended adjuvant therapy with neratinib to follow trastuzumab in patients with early-stage, HER2-positive breast cancer. Neratinib causes substantial diarrhea, and diarrhea prophylaxis must be used. Additional information can be found at www.asco.org/breast-cancer-guidelines .

    1996-01-01

    Purpose: The results of therapy in 288 men with pathologic Stage C prostate cancer who underwent radical retropubic prostatectomy (RRP) were analyzed to determine the effects of adjuvant therapy. Methods and Materials: Twenty-seven of the 288 patients received preoperative neoadjuvant hormonal therapy (leuprolide acetate). Postoperatively, 60 patients received adjuvant radiotherapy (RT) to the prostate bed. Follow-up ranged from 3 to 83 months (median = 32 months). Freedom from failure (FFF) was defined as maintaining a serum PSA level of ≤ 0.3 ng/ml. Results: The FFF was 61% at 3 years and 45% at 5 years for the entire group. The FFF following RRP plus RT was 75% at 3 years and 57% at 5 years as compared to 56% at 3 years and 40% at 5 years for RRP without RT (p = 0.049). The FFF following RRP plus neoadjuvant hormonal therapy was 58% at 3 years and 40% at 5 years as compared to 60% at 3 years and 45% at 5 years following RRP without hormonal therapy (p = 0.3). In patients without seminal vesicle (SV) invasion, the FFF was 81% at 3 and 5 years for RRP plus RT as compared to 61% at 3 years and 50% at 5 years for RRP without RT (p = 0.01). In patients with SV invasion, the FFF was 61% at 3 years and 36% at 5 years for RRP plus RT as compared to 44% at 3 years and 23% at 5 years for RRP without RT (p = 0.23). The projected local control rate was 83% at 5 years for those with RRP alone as compared to 100% for RRP plus RT (p = 0.02). Survival at 5 years was projected to be 92% and was not significantly altered by the administration of adjuvant therapies. Conclusions: Postoperative RT was associated with significantly improved local control and FFF rates, especially in patients with tumors which did not involve the seminal vesicles

    Purpose: Adjuvant and salvage irradiation have been shown to improve local control after radical prostatectomy for prostatic cancer in patients with high risk pathologic features, rising PSA, or evidence of local failure. Transient androgen deprivation combined with primary irradiation has resulted in improved local control and biochemical disease free survival in patients with locally advanced, unresected, prostate cancer. This retrospective study evaluates whether transient androgen blockade improves the outcome from post-prostatectomy irradiation given as either adjuvant or salvage therapy. Methods: From August, 1985 to December, 1995, 105 patients were treated with radiotherapy to the prostatic fossa following radical prostatectomy for adenocarcinoma of the prostate. No patient had clinically or radiographically evident distant disease. Median follow-up was 4.6 years from the date of surgery and 3.2 years from completion of radiotherapy. Findings at prostatectomy included capsular penetration in 38 patients, seminal vesicle involvement in 42 patients, lymph node involvement in 15 patients, and positive surgical margins in 70 patients. Treatment was administered as adjuvant therapy for high risk pathologic features in 39 patients, for persistent or rising PSA in 52 patients, or for clinically evident local recurrence in 14 patients. Of the 105 patients, 32 received combined androgen deprivation/radiotherapy and 73 received radiotherapy alone. Both groups received 60-70 Gy in 2 Gy daily fractions to the prostatic fossa. Selected patients with poor prognostic features received pelvic irradiation to a median dose of 50 Gy. Androgen deprivation typically consisted of Lupron and Flutamide for 4 to 6 months before, during, and in selected cases, after irradiation. No patients received maintenance androgen deprivation or underwent orchiectomy. Tumor stage, lymph node status, Gleason sum, and indications for treatment did not differ significantly between the two groups

    Purpose: To describe the anatomic distribution of regionally recurrent disease in patients with stage III melanoma in the axilla after curative-intent surgery with and without adjuvant radiation therapy. Methods and Materials: A single-institution, retrospective analysis of a prospective database of 277 patients undergoing curative-intent treatment for stage III melanoma in the axilla between 1992 and 2012 was completed. For patients who received radiation therapy and those who did not, patterns of regional recurrence were analyzed, and univariate analyses were performed to assess for potential factors associated with location of recurrence. Results: There were 121 patients who received adjuvant radiation therapy because their clinicopathologic features conferred a greater risk of regional recurrence. There were 156 patients who received no radiation therapy. The overall axillary control rate was 87%. There were 37 patients with regional recurrence; 17 patients had received adjuvant radiation therapy (14%), and 20 patients (13%) had not. The likelihood of in-field nodal recurrence was significantly less in the adjuvant radiation therapy group (P=.01) and significantly greater in sites adjacent to the axilla (P=.02). Patients with high-risk clinicopathologic features who did not receive adjuvant radiation therapy also tended to experience in-field failure rather than adjacent-field failure. Conclusions: Patients who received adjuvant radiation therapy were more likely to experience recurrence in the adjacent-field regions rather than in the in-field regions. This may not simply reflect higher-risk pathology. Using this data, it may be possible to improve outcomes by reducing the number of adjacent-field recurrences after adjuvant radiation therapy.

    2013-01-01

    To investigate the increase in MRI contrast enhancement (CE) occurring in glioblastoma during the period between surgery and initiation of chemo-radiotherapy, thirty-seven patients with newly diagnosed glioblastoma were analyzed by early post-operative magnetic resonance (EPMR) imaging within three days of surgery and by pre-adjuvant magnetic resonance (PAMR) examination before adjuvant therapy. Areas of new CE were investigated by use of EPMR diffusion-weighted imaging and PAMR perfusion imaging (by arterial spin-labeling). PAMR was acquired, on average, 29.9 days later than EPMR (range 20-37 days). During this period an increased area of CE was observed for 17/37 patients. For 3/17 patients these regions were confined to areas of reduced EPMR diffusion, suggesting postsurgical infarct. For the other 14/17 patients, these areas suggested progression. For 11/17 patients the co-occurrence of hyperperfusion in PAMR perfusion suggested progression. PAMR perfusion and EPMR diffusion did not give consistent results for 3/17 patients for whom small new areas of CE were observed, presumably because of the poor spatial resolution of perfusion imaging. Before initiation of adjuvant therapy, areas of new CE of resected glioblastomas are frequently observed. Most of these suggest tumor progression, according to EPMR diffusion and PAMR perfusion criteria.

    The role of adjuvant chemoradiation therapy for ampullary carcinoma is unknown. Previous literature suggests that certain populations with high risk factors for recurrence may benefit from adjuvant chemoradiation. We combined the experience of two institutions to better delineate which patients may benefit from adjuvant chemoradiation. Patients who underwent curative surgery for ampullary carcinoma at the Johns Hopkins Hospital (n = 290; 1992-2007) and at the Mayo Clinic (n = 130; 1977-2005) were reviewed. Patients with <60 days of follow-up, metastatic disease at surgery, or insufficient pathologic data were excluded. The final combined study consisted of 186 patients (n = 104 Johns Hopkins, n = 82 Mayo). Most patients received 5-FU based chemoradiation with conformal radiation. Cox proportional hazards models were used for survival analysis. Median overall-survival was 39.9 months with 2- and 5-year survival rates of 62.4% and 39.1%. On univariate analysis, adverse prognostic factors for overall survival included T3/T4 stage disease (RR = 1.86, p = 0.002), node positive status (RR = 3.18, p < 0.001), and poor histological grade (RR = 1.69, p = 0.011). Patients who received adjuvant chemoradiation (n = 66) vs. surgery alone (n = 120) showed a higher rate of T3/T4 stage disease (57.6% vs. 30.8%, P < 0.001), lymph node involvement (72.7% vs. 30.0%, P < 0.001), and close or positive margins (4.6% vs. 0.0%, P = 0.019). Five year survival rates among node negative and node positive patients were 58.7% and 18.4% respectively. When compared with surgery alone, use of adjuvant chemoradiation improved survival among node positive patients (mOS 32.1 vs. 15.7 mos, 5 yr OS: 27.5% vs. 5.9%; RR = 0.47, P = 0.004). After adjusting for adverse prognostic factors on multivariate analysis, patients treated with adjuvant chemoradiation demonstrated a significant survival benefit (RR = 0.40, P < 0.001). Disease relapse occurred in 37.1% of all patients, most commonly metastatic

    Following potentially curative surgery for resectable adenocarcinoma of the rectum, the incidence of local failure is 15% to 35% in stages T 3 N 0 and T 1 N 1-2 and 45% to 65% in stages T 4 N 0 , T 3 N 1-2 , and T 4 N 1-2 . In order to determine the impact of pelvic radiation therapy±chemotherapy on local failure and survival, we present a prospective analysis of our results of 25 patients treated with this approach. The median follow-up was 30 months (range: 10 to 48 months). For the total patients group the 3-year actuarial survival was 74%. In order to more accurately analyze the patterns of failure, actuarial calculations were performed. The actuarial incidence of local failure as a component of failure was 17%. For patients with node positive disesse (T 1-4 N 1-2 ), the overall survival was 80%, and the actuarial incidence of local failure as a component of failure was 15%. Complications were acceptable and the incidence of small bowel obstruction requiring surgery was 8%. (author)

    Purpose: To retrospectively evaluate the outcome and toxicity in patients receiving high-dose (>69 Gy) adjuvant radiotherapy (HD-ART) and the impact of androgen deprivation therapy (ADT). Methods and Materials: Between 1999 and 2008, 225 node-negative patients were referred for HD-ART with or without ADT to two large academic institutions. Indications for HD-ART were extracapsular extension, seminal vesicle invasion (SVI), and/or positive surgical margins at radical prostatectomy (RP). A dose of at least 69.1 Gy was prescribed to the prostate bed and seminal vesicle bed. The ADT consisted of a luteinizing hormone–releasing hormone analog. The duration and indication of ADT was left at the discretion of the treating physician. The effect of HD-ART and ADT on biochemical (bRFS) and clinical (cRFS) relapse-free survival was examined through univariate and multivariate analysis, with correction for known patient- and treatment-related variables. Interaction terms were introduced to evaluate effect modification. Results: After a median follow-up time of 5 years, the 7-year bRFS and cRFS were 84% and 88%, respectively. On multivariate analysis, the addition of ADT was independently associated with an improved bRFS (hazard ratio [HR] 0.4, p = 0.02) and cRFS (HR 0.2, p = 0.008). Higher Gleason scores and SVI were associated with decreased bRFS and cRFS. A lymphadenectomy at the time of RP independently improved cRFS (HR 0.09, p = 0.009). The 7-year probability of late Grade 2–3 toxicity was 29% and 5% for genitourinary (GU) and gastrointestinal (GI) symptoms, respectively. The absolute incidence of Grade 3 toxicity was <1% and 10% for GI and GU symptoms, respectively. The study is limited by its retrospective design and the lack of a standardized use of ADT. Conclusions: This retrospective study shows significantly improved bRFS and cRFS rates with the addition of ADT to HD-ART, with low Grade 3 gastrointestinal toxicity and 10% Grade 3 genitourinary toxicity.

  16. Physical Therapy Adjuvants to Promote Optimization of Walking Recovery after Stroke

    Full Text Available Stroke commonly results in substantial and persistent deficits in locomotor function. The majority of scientific inquiries have focused on singular intervention approaches, with recent attention given to task specific therapies. We propose that measurement should indicate the most critical limiting factor(s to be addressed and that a combination of adjuvant treatments individualized to target accompanying impairment(s will result in the greatest improvements in locomotor function. We explore training to improve walking performance by addressing a combination of: (1 walking specific motor control; (2 dynamic balance; (3 cardiorespiratory fitness and (4 muscle strength and put forward a theoretical framework to maximize the functional benefits of these strategies as physical adjuvants. The extent to which any of these impairments contribute to locomotor dysfunction is dependent on the individual and will undoubtedly change throughout the rehabilitation intervention. Thus, the ability to identify and measure the relative contributions of these elements will allow for identification of a primary intervention as well as prescription of additional adjuvant approaches. Importantly, we highlight the need for future studies as appropriate dosing of each of these elements is contingent on improving the capacity to measure each element and to titrate the contribution of each to optimal walking performance.

    Background and purpose: Uterine carcinosarcoma is an aggressive neoplasm and the benefit of adjuvant radiation therapy (RT) is unclear. This retrospective study analyzes the influence of RT on survival using a large population database. Materials and methods: Data were obtained from the Surveillance, Epidemiology, and End Results (SEER) program of the US National Cancer Institute. Women with uterine carcinosarcoma who underwent primary surgery were eligible. Survival rates and multivariate analyses were performed by standard methods. Results: Of the 2461 women in the analysis, 890 received adjuvant RT. Five-year rates of overall survival were 41.5% and 33.2% (P < 0.001) and uterine-specific survival were 56.0% and 50.8% (P = 0.005), for women receiving RT compared to those who did not. Women with stages I-III disease experienced a benefit in overall survival (HR 0.87, P = 0.03) while women with stage IV disease experienced benefits in overall (HR 0.63, P < 0.001) and uterine-specific survival (HR 0.63, P = 0.004) with RT. Conclusions: RT predicted for improved overall and disease specific survival in women with uterine carcinosarcoma within the SEER database. The benefit in disease specific survival was restricted to stage IV disease. These benefits may indicate a role for adjuvant RT in future prospective trials in the treatment of uterine carcinosarcoma

    Purpose: To study the impact of dose fractionation of adjuvant radiation therapy (RT) on local recurrence (LR) and the relation of LR to radiation fields. Methods and Materials: LR rates were analyzed in 462 adult patients with soft tissue sarcoma who underwent surgical excision and adjuvant RT at five Scandinavian sarcoma centers from 1998 to 2009. Medical records were reviewed for dose fractionation parameters and to determine the location of the LR relative to the radiation portals. Results: Fifty-five of 462 patients developed a LR (11.9%). Negative prognostic factors included intralesional surgical margin (hazard ratio [HR]: 7.83, 95% confidence interval [CI]: 3.08-20.0), high malignancy grade (HR: 5.82, 95% CI: 1.31-25.8), age at diagnosis (HR per 10 years: 1.27, 95% CI: 1.03-1.56), and malignant peripheral nerve sheath tumor histological subtype (HR: 6.66, 95% CI: 2.56-17.3). RT dose was tailored to margin status. No correlation between RT dose and LR rate was found in multiple Cox regression analysis. The majority (65%) of LRs occurred within the primary RT volume. Conclusions: No significant dose–response effect of adjuvant RT was demonstrated. Interestingly, patients given 45-Gy accelerated RT (1.8 Gy twice daily/2.5 weeks) had the best local outcome. A total dose of 50 Gy in 25 fractions seemed adequate following wide margin surgery. The risk of LR was associated with histopathologic subtype, which should be included in the treatment algorithm of adjuvant RT in soft tissue sarcoma.

Complications of chemotherapy have forced physicians to study antioxidant use as adjunctive treatment in cancer. This study aimed to evaluate the antioxidant role of vitamin E and N-acetyl cysteine (NAC in overcoming treatment-induced toxicity in acute lymphoblastic leukaemia (ALL during the intensive period of chemo-/radiotherapy, almost the first two months of treatment. Forty children newly diagnosed with ALL were enrolled in this study.

    Malignant pleural mesothelioma (MPM) is an aggressive neoplasia. Multidisciplinary treatments, including the association of induction and/or adjuvant therapeutic regimens with surgery, have been reported to give encouraging results. Current therapeutic options are not well standardized yet, especially regarding the best association between surgery and medical treatments. The present review aims to assess safety, efficacy and outcomes of different therapies for MPM. Areas covered: This article focuses on the multimodality treatment of mesothelioma. A systematic review was performed by using electronic databases to identify studies that considered induction and adjuvant approaches in MPM therapy in a multidisciplinary setting, including surgery. Endpoints included overall survival, disease free survival, disease recurrence, and complications. Expert commentary: This systematic review offers a comprehensive view of current multidisciplinary therapeutic strategies for MPM, suggesting that multimodality therapy offers acceptable outcomes with better results reported for trimodality approaches. Individualization of care for each patient is fundamental in choosing the most appropriate treatment. The growing complexity of treatment protocols mandates that MPM patients be referred to specialized Centers, in which every component of the interdisciplinary team can provide the necessary expertise and quality of care.

    Preventing breast recurrence after breast-conserving surgery is an important issue. The main factors contributing to breast recurrences are positive margins and absence of radiotherapy. In late years a standard adjuvant treatment is widely used in Japan. We examined whether these standard treatments contributed to reduction of a breast recurrence. By March 2003, 845 patients were treated by breast-conserving surgery, and the cases were divided into two groups by operation period; 426 cases until 1998 (the first half group) and 202 patients with follow-up periods more than 2 years (the latter group). There were much positive margins and patients with radiotherapy in a latter group in background factor. An endocrine therapy for estrogen receptor (ER) positive was performed in 68.1% in first half period, and in contrast 94.2% in the latter period, and chemotherapy was performed in 87% (mainly Epirubicin) for ER negative in the latter period, and 77% (mainly oral agent) in the first half period. There was a significant difference of breast recurrence-free survival between 2 groups; an early recurrence was seen in 19 cases (4.5%) in the first half period and 2 cases (1.0%) in the latter group. In particular the difference was significant in patients with absence of radiotherapy or negative ER. Multivariate analysis revealed that the operation time was a significant factor for breast recurrence. In conclusion, an apparent reduction of breast recurrence may be brought by a standard adjuvant therapy. (authors)

    In modern surgical oncology, adjuvant therapies are important complementary strategies. In local advanced carcinomas of the gastrointestinal tract, 5-year survival data are still disappointing despite standardized surgery. In this context, it has to be differentiated between adjuvant therapy following complete tumor exstirpation (so-called UICC R 0 resection) and additive therapies following incomplete tumor resections (UICC R 1 or R 2 resection). Modalities in the adjuvant setting are chemotherapy, radiotherapy or the combined radio-/chemotherapy. In esophageal and gastric cancer there is up to now no benefit of postoperative adjuvant therapy. In pancreatic cancer, there are studies indicating a benefit of combined radio-/chemotherapy after complete tumor resection. A standard adjuvant chemotherapeutic treatment is proven in colon cancer stage III (Dukes C) with levamisole and 5-FU. Completely resected rectal carcinoma should be treated postoperatively with combined radio-/chemotherapy. In the common clinical or practical setting, adjuvant therapy is indicated only in locally advanced gastrointestinal tumors following R 0 resection. Postoperative therapy following incomplete tumor resection has its reason only in a palliative intention. (orig.) [de

  7. Postoperative radiation therapy and adjuvant chemoimmunotherapy in breast cancer. Aspects of timing and immune competence

    Klefstroem, P.; Nuortio, L.; Taskinen, E.

    The effects of radiation therapy and adjuvant chemoimmunotherapy on the immune competence of patients with breast cancer were investigated. The tests performed included intradermal tuberculin tests, T- and B-lymphocyte counts, and lymphocyte blast transformation tests; phytohemagglutinin (PHA), concanavalin A (ConA) and pokeweed mitogen (PMW) were used as mitogens. Enhancement in lymphocyte proliferative response to mitogenic stimulation by PHA and PMW was seen in patients after 3 courses of chemotherapy + levamisole, whereas irradiation given after chemotherapy caused long-lasting depression in response to PHA and PWM (not significant). T-lymphocyte counts were also lower after irradiation than after chemoimmunotherapy. Clinically, the 16 patients treated with radiation therapy after chemotherapy exhibited a higher recurrence rate than the 24 patients treated first by irradiation. Enhanced reactivity to tuberculin tests occurred generally in patients receiving a planned treatment including irradiation, chemotherapy (5-fluorouracil, doxorubicin, cyclophosphamide) and levamisole. Enhancement of reactivity was seen more often in patients who had not relapsed.

    Full Text Available Abstract The treatment of soft tissue tumors needs the coordinated adoption of surgery with radiation therapy and eventually, chemotherapy. The radiation therapy (delivered with a linear accelerator can be preoperative, intraoperative, or postoperative. In selected patients adjuvant brachytherapy can be adopted. The goal of these associations is to achieve tumor control while maximally preserving the normal tissues from side effects. Unfortunately, the occurrence of local and distant complications is still elevated. Electrochemotherapy is a novel technique that combines the administration of anticancer agents to the application of permeabilizing pulses in order to increase the uptake of antitumor molecules. While its use in humans is still confined to the treatment of cutaneous neoplasms or the palliation of skin tumor metastases, in veterinary oncology this approach is rapidly becoming a primary treatment. This review summarizes the recent progresses in preclinical oncology and their possible transfer to humans.

    Since 1969, Bleomycin (BLM) has been used in three different ways at the Radium Centre in Copenhagen. First BLM given as the sole treatment led to complete regressions in 12% of 138 patients. Secondly BLM was used as simultaneous adjuvant in radiation therapy for 86 previously untreated patients, but 66% developed mucositis which disrupted the treatment. In a third period BLM was therefore combined sequentially with radiation, administered for 2 weeks prior to radiation therapy to 142 patients. The tumour shrinkage achieved with preirradiation BLM was very pronounced in 38 % of cases. 101 patients with T3 tumours have been observed for a minimum of 3 years. The prognostic value of the degree of shrinkage achieved with preirradiation BLM treatment is discussed.

    The randomised controlled clinical trial (RCT) is a powerful instrument to evaluate different therapeutic regimens. In a survey among 115 physicians visiting the 25th annual meeting of the Surgical Society of Berlin and Brandenburg, the RCT was judged to be very important when changes of therapeutic strategies are discussed. 90 % of all participants claimed to use data from RCTs in the clinical routine and 89 % would participate in such a trial. In official (e. g. discussions during coffee breaks at scientific meetings) or non-medical (e. g. non-scientific press or media) sources of information were assessed as irrelevant for decisions regarding therapeutic strategies. However, in contrast to this view laparoscopic cholecystectomy was introduced into clinical practice rapidly because patients informed by external (non-medical) sources preferred to be operated on with the "modern" technique. Clinical trials with a high level of evidence had no relevant influence on the rapid distribution of laparoscopic cholecystectomy. Controversial discussions concerning the extent of lymphadenectomy with gastric resection for carcinoma demonstrate that the value of excellent clinical RCTs is low if their results challenge a stable paradigma of the surgical scientific society. To allow a rational judgement, new surgical technologies should undergo a scientific gradual evaluation in agreement with the principles of evidence based medicine.

    No evidence-based recommendations exist for the management of infectious bursitis. We examined epidemiology and risk factors for recurrence of septic bursitis. Specifically, we compared outcome in patients receiving bursectomy plus short-course adjuvant antibiotic therapy (7 days). Retrospective study of adult patients with infectious olecranon and patellar bursitis requiring hospitalization at Geneva University Hospital from January 1996 to March 2009. We identified 343 episodes of infectious bursitis (237 olecranon and 106 patellar). Staphylococcus aureus predominated among the 256 cases with an identifiable pathogen (85%). Three hundred and twelve cases (91%) were treated surgically; 142 (41%) with one-stage bursectomy and closure and 146 with two-stage bursectomy. All received antibiotics for a median duration of 13 days with a median intravenous component of 3 days. Cure was achieved in 293 (85%) episodes. Total duration of antibiotic therapy [odds ratio (OR) 0.9; 95% confidence interval (95% CI) 0.8-1.1] showed no association with cure. In multivariate analysis, only immunosuppression was linked to recurrence (OR 5.6; 95% CI 1.9-18.4). Compared with 14 days of antibiotic treatment (OR 0.9; 95% CI 0.1-10.7) was equivalent, as was the intravenous component (OR 1.1; 95% CI 1.0-1.3). In severe infectious bursitis requiring hospitalization, adjuvant antibiotic therapy might be limited to 7 days in non-immunosuppressed patients.

    Purpose: The combination of pelvic radiotherapy and 5-fluorouracil-based chemotherapy is associated with an increase in acute gastrointestinal toxicity during rectal adjuvant therapy, most notably an increased incidence of diarrhea. Previous randomized, prospective studies have limited their analysis to presenting rates of severe and life-threatening diarrhea (Grade 3 or greater), and few data are available detailing the extent of mild to moderate diarrhea. To provide baseline data for future studies, we conducted a detailed analysis of diarrhea from a prior clinical trial of adjuvant therapy for rectal cancer. Methods and Materials: In a multiinstitutional clinical trial, 204 eligible patients with rectal carcinoma that either was deeply invasive (T3-T4) or involved regional lymph nodes were randomized to receive either postoperative pelvic radiotherapy alone (45 to 50.4 Gy) or pelvic radiotherapy and bolus 5-fluorouracil-based chemotherapy. Toxicity was assessed prospectively. Results: For the 99 eligible patients who received pelvic radiotherapy alone, rates of Grades 0, 1, 2, 3, and 4 diarrhea during treatment were 59, 20, 17, 4, and 0%, respectively. For the 96 eligible patients who received radiotherapy and 5-fluorouracil, the overall rates of grades 0, 1, 2, 3, and 4 diarrhea were 21, 34, 23, 20, and 2%, respectively. The increased rates of diarrhea during adjuvant rectal therapy were manifested across all toxicity levels for patients receiving chemotherapy and pelvic radiotherapy. Of primary clinical importance is the substantial increase in severe or life-threatening diarrhea (Grade 3 or more) (22 vs. 4%, p = 0.001) Additionally, increased rates of any diarrhea and also severe or life-threatening diarrhea were observed in patients who had a low anterior resection compared with those who had an abdominoperineal resection (p < 0.001 and p = 0.006, respectively). Conclusion: These results will be of value as a baseline for investigators who want to use

    Purpose: To inform prospective trials of adjuvant radiation therapy (adj-RT) for bladder cancer after radical cystectomy, a locoregional failure (LF) risk stratification was proposed. This stratification was developed and validated using surgical databases that may not reflect the outcomes expected in prospective trials. Our purpose was to assess sources of bias that may affect the stratification model's validity or alter the LF risk estimates for each subgroup: time bias due to evolving surgical techniques; trial accrual bias due to inclusion of patients who would be ineligible for adj-RT trials because of early disease progression, death, or loss to follow-up shortly after cystectomy; bias due to different statistical methods to estimate LF; and subgrouping bias due to different definitions of the LF subgroups. Methods and Materials: The LF risk stratification was developed using a single-institution cohort (n=442, 1990-2008) and the multi-institutional SWOG 8710 cohort (n=264, 1987-1998) treated with radical cystectomy with or without chemotherapy. We evaluated the sensitivity of the stratification to sources of bias using Fine-Gray regression and Kaplan-Meier analyses. Results: Year of radical cystectomy was not associated with LF risk on univariate or multivariate analysis after controlling for risk group. By use of more stringent inclusion criteria, 26 SWOG patients (10%) and 60 patients from the single-institution cohort (14%) were excluded. Analysis of the remaining patients confirmed 3 subgroups with significantly different LF risks with 3-year rates of 7%, 17%, and 36%, respectively (P<.01), nearly identical to the rates without correcting for trial accrual bias. Kaplan-Meier techniques estimated higher subgroup LF rates than competing risk analysis. The subgroup definitions used in the NRG-GU001 adj-RT trial were validated. Conclusions: These sources of bias did not invalidate the LF risk stratification or substantially change the model's LF estimates.

    Full Text Available Worldwide, around 14 million individuals are coinfected with both tuberculosis (TB and human immunodeficiency virus (HIV. In coinfected individuals, both pathogens weaken immunological system synergistically through mechanisms that are not fully understood. During both HIV and TB infections, there is a chronic state of inflammation associated to dramatic changes in immune cytokine and endocrine hormone levels. Despite this, the relevance of immunoendocrine interaction on both the orchestration of an effective immune response against both pathogens and the control of the chronic inflammation induced during HIV, TB, or both infections is still controversial. The present study reviews immunoendocrine interactions occurring during HIV and TB infections. We also expose our own findings on immunoendocrine cross talk in HIV-TB coinfection. Finally, we evaluate the use of adrenal hormones and their derivatives in immune-therapy and discuss the use of some of these compounds like the adjuvant for the prevention and treatment of TB in HIV patients.

    1999-01-01

    Purpose: To evaluate in a porcine model of acute deep vein thrombosis (DVT) the efficacy of dalteparin and antithrombin with respect to heparin for local adjuvant therapy during selective thrombolysis, and the utility of nitroglycerin and iloprost as heparin supplements. Methods: DVT was induced in both hind limbs using a previously described technique (n = 20). Thirty minutes later, the animal was heparinized (2500 IU IV), and bilateral sequestrated thrombolysis was performed using 8 mg alteplase: both external iliac veins were endoluminally occluded with Swan-Ganz catheters, and a multi-sideport infusion wire coaxially introduced through each catheter and advanced into the ipsilateral popliteal vein. In the control limbs, tissue plasminogen activator (tPA) 8 mg was injected as 0.8-ml boluses at 3-min intervals for 2 hr as a 0.25-mg/ml solution containing heparin 50 IU/ml (n 20). On the contralateral side, heparin was substituted with either dalteparin 50 IU/ml (n = 5) or antithrombin 12.5 IU/ml (n = 5), or supplemented with either nitroglycerin 0.075 mg/ml (n = 5) or iloprost (150 ng/ml) (n = 5). Blood samples were taken at predetermined intervals to measure the activated partial thromboplastin time (aPTT), prothrombin time (PT), and fibrinogen concentration. At autopsy, the thrombus mass in the iliofemoral veins was measured, and the extent of residual thrombosis in the venous tributaries graded at four sites. Results: Bilateral thrombolysis was successfully completed in all animals. The median thrombus mass in the iliofemoral veins after thrombolysis was 0.48 g (range 0.06-1.58 g), 0.95 g (0.59-1.29 g), 0.74 g (0.52-0.96 g), and 0.29 g (0.0-0.77 g) for dalteparin, antithrombin, iloprost, and nitroglycerin respectively, as compared with 0.53 g (0.18-0.88 g) (p = 0.69), 0.97 g (0.46-1.15 g) (p = 0.69), 0.53 g (0.48-1.10 g) (p = 0.69), and 0.18 g (0.13-1.04 g) (p = 0.5) for the respective controls. Likewise, the severity of residual thrombosis in the venous

    Studies show adjuvant endocrine therapy increases survival and decreases risk of breast cancer recurrence for hormone receptor-positive tumors. Yet studies also suggest that adherence rates among women taking this therapy may be as low as 50% owing largely to adverse side effects. Despite these rates, research on longitudinal patient decision making regarding this therapy is scant. We sought to map the decision-making process for women considering and initiating adjuvant endocrine therapy, paying particular attention to patterns of uncertainty and decisional change over time. A longitudinal series of semistructured interviews conducted at a multispecialty health care organization in Northern California with 35 newly diagnosed patients eligible for adjuvant endocrine therapy were analyzed. Analysis led to the identification and indexing of 3 new decision-making constructs-decisional phase, decisional direction, and decisional resolve-which were then organized using a visual matrix and examined for patterns characterizing the decision-making process. Our data reveal that most patients do not make a single, discrete decision to take or not take hormone therapy but rather traverse multiple decisional states, characterized by 1) phase, 2) direction, and 3) strength of resolve. Our analysis tracks these decisional states longitudinally using a grayscale-coded matrix. Our data show that decisional resolve wavers not just when considering therapy, as the existing concept of decisional conflict suggests, but even after initiating it, which may signal future decisions to forgo therapy. Adjuvant endocrine therapy, like other chronic care decisions, has a longer decision-making process and implementation period. Thus, theoretical, empirical, and clinical approaches should consider further exploring the new concept and measurement of decisional resolve, as it may help to improve subsequent medication adherence. © The Author(s) 2016.

    Long-term data from three randomized trials have demonstrated that adjuvant radiation therapy (ART) reduces the rate of biochemical failure in high-risk men following radical prostatectomy (RP). One of these trials has shown a survival advantage. We investigated the rate of ART in Victoria and the predictors for this treatment. We analysed data from eligible patients who were notified to the Victorian Prostate Cancer Registry (PCR) by 37 Victorian hospitals between 1 August 2008 and 31 October 2011. We defined ART as radiation therapy (RT) delivered within 6 months of RP. Predictors of ART receipt were modelled using adjusted and unadjusted logistic regression. There were 4626 eligible cases from which 2018 underwent RP with recorded date of surgery. Of these eligible prostatectomy cases, a total of 89 received ART. A subgroup of 833 men had an adverse pathologic feature, of whom 78 received ART. In a multivariate model, pathologic tumour stage pT3a (odds ratio (OR) 2.64; 95% confidence interval (CI) 1.4–5.00; P = 0.003), pT3b (OR 4.58; 95% CI 2.12–9.89; P = 0.000), a positive surgical margin (OR 8.91; 95% CI 4.61–17.2; P = 0.000) and pathologic Gleason grade >7 (OR 7.18; 95% CI 1.54–33.6; P = 0.012) predicted receipt of ART. Adverse pathologic features and high pathologic Gleason score predict for receiving ART in Victorian men after RP, but overall, ART is not commonly prescribed. This finding is consistent with other published series and may reflect clinician scepticism regarding the benefit of ART over salvage RT and concern about toxicity and the risk of over treatment.

    Despite the benefits of adjuvant endocrine therapy for hormone receptor positive breast cancer, many women are non-adherent or discontinue endocrine treatment early. We studied differences in adherence to adjuvant endocrine therapy by ethnicity in a cohort of New Zealand women with breast cancer and its impact on breast cancer outcomes. We analysed data on women (n = 1149) with newly diagnosed hormone receptor positive, non-metastatic, invasive breast cancer who were treated with adjuvant endocrine therapy in the Waikato during 2005-2011. Linked data from the Waikato Breast Cancer Registry and National Pharmaceutical Database were examined to identify differences by ethnicity in adherence to adjuvant endocrine therapy and the effect of sub-optimal adherence on cancer recurrence and mortality. Overall, a high level of adherence of ≥80% was observed among 70.4% of women, which declined from 76.8% to 59.3% from the first to fifth year of treatment. Māori women were significantly more likely to be sub-optimally adherent (breast cancer mortality (HR = 1.77, 95% CI 1.05-2.99) and recurrence (HR = 2.14, 95% CI 1.46-3.14). Sub-optimal adherence to adjuvant endocrine therapy was a likely contributor for breast cancer mortality inequity between Māori and European women, and highlights the need for future research to identify effective ways to increase adherence in Māori women.

    With this study we want to evaluate the role of dexamethasone adjuvant treatment in different clinical forms of invasive meningococcal diseases. WORK METHODS: This was a randomized, open label trial that was conducted in 147 individuals with meningococcal sepsis. All of the cases have been divided in two groups: (1) Cases with meningococcal disease and CNS infection, and (2) Cases with meningococcal disease and no affection of the CNS. Cases from both groups were treated with dexamethasone, 0.15 mg/kg, every 6 h, for 4 (four) days, as adjuvant therapy. Cases which were not treated with dexamethasone were used as control group. From overall number of cases, in 130 of them, the meningococcal disease was accompanied with meningitis; in other 17 cases only signs of sepsis were present. In both clinical forms, the dexamethasone was used in 92 cases. The higher mortality rate is registered among the cases without meningitis, 17.65%, compared with 6.92% which is registered among cases with meningitis. The overall mortality rate among all cases was 8.2%. The significant difference was recorded only on CSF sugar level between two groups (treated or not with dexamethasone) on the day 1-4 of the hospitalization. Our epidemiological data are in correlation with data from other epidemiological studies. Most of the cases 69.4%, were more than 12 hours sick at home before the hospitalization, 7.5 % of cases were hospitalized within 12 hours from the onset of the diseases, while 23.1% of cases data are missing. This is in correlation with similar data from other studies. Dexamethasone has a limited effect on outcome of the invasive meningococcal disease. Dexamethasone had some effect only during the days of administration in cases with clinical form of sepsis with meningitis, by normalizing the values of CSF sugar earlier.

    Cancer is associated with epigenetic (i.e., histone hypoacetylation) and metabolic (i.e., aerobic glycolysis) alterations. Levels of N-acetyl-L-aspartate (NAA), the primary storage form of acetate in the brain, and aspartoacylase (ASPA), the enzyme responsible for NAA catalysis to generate acetate, are reduced in glioma; yet, few studies have investigated acetate as a potential therapeutic agent. This preclinical study sought to test the efficacy of the food additive Triacetin (glyceryl triacetate, GTA) as a novel therapy to increase acetate bioavailability in glioma cells. The growth-inhibitory effects of GTA, compared to the histone deacetylase inhibitor Vorinostat (SAHA), were assessed in established human glioma cell lines (HOG and Hs683 oligodendroglioma, U87 and U251 glioblastoma) and primary tumor-derived glioma stem-like cells (GSCs), relative to an oligodendrocyte progenitor line (Oli-Neu), normal astrocytes, and neural stem cells (NSCs) in vitro. GTA was also tested as a chemotherapeutic adjuvant with temozolomide (TMZ) in orthotopically grafted GSCs. GTA-induced cytostatic growth arrest in vitro comparable to Vorinostat, but, unlike Vorinostat, GTA did not alter astrocyte growth and promoted NSC expansion. GTA alone increased survival of mice engrafted with glioblastoma GSCs and potentiated TMZ to extend survival longer than TMZ alone. GTA was most effective on GSCs with a mesenchymal cell phenotype. Given that GTA has been chronically administered safely to infants with Canavan disease, a leukodystrophy due to ASPA mutation, GTA-mediated acetate supplementation may provide a novel, safe chemotherapeutic adjuvant to reduce the growth of glioma tumors, most notably the more rapidly proliferating, glycolytic and hypoacetylated mesenchymal glioma tumors. © 2013 UICC.

    Full Text Available Objective: to evaluate the efficiency and safety of using the luteinizing hormone releasing hormone leuprorelin with the Atrigel delivery system in doses of 7.5, 22.5, and 45 mg as an adjuvant regimen in high- and moderate-risk cancer patients who have received high-intensity focused ultrasound (HIFU therapy.Subjects and methods. Moderate- and high-risk locally advanced prostate cancer (PC patients treated with HIFU (n = 28 and HIFU in combination with hormone therapy during 6 months (n = 31 were examined.Results. The investigation has shown that leuprorelin acetate monotherapy used within 6 months after HIFU therapy can achieve the highest reduction in prostate-specific antigen levels and positively affect the symptoms of the disease. HIFU in combination with androgen deprivation substantially diminishes the clinical manifestations of the disease and improves quality of life in HIFU-treated patients with PC, by reducing the degree of infravesical obstruction (according to uroflowmetric findings and IPSS scores, and causes a decrease in prostate volume as compared to those who have undergone HIFU only. Treatment with leuprorelin having the Atrigel delivery system has demonstrated the low incidence of adverse reactions and good tolerability.

    This single-center retrospective study of prospectively collected data was aimed at comparing the clinical outcomes of positron emission tomography/computed tomography (PET/CT) for patients with oral cavity squamous cell carcinoma (OSCC) with symptomatic recurrences identified by PET/CT imaging following adjuvant therapy (Group A) versus those of cases with asymptomatic recurrences diagnosed through periodic post-adjuvant therapy PET/CT surveillance (Group B). We also sought to establish the priority of salvage therapy in the two study groups. We identified 111 patients with advanced resected OSCC who developed recurrences following adjuvant therapy (51 in Group A and 60 in Group B). Histopathology served as the gold standard for recurrent lesions. The impact of post-adjuvant therapy PET/CT surveillance was examined with Kaplan-Meier curves and Cox proportional hazards regression models. The 2-year DSS and OS rates were marginally or significantly higher in Group B than in Group A (P = 0.073 and P = 0.025, respectively). Time-dependent ROC curve analysis demonstrated that the optimal cutoff values for time to positive PET/CT findings in relation to OS were 12 months for Group A and 9 months for Group B, respectively. Independent risk factors identified in multivariate analyses were used to devise two prognostic scoring systems for 2-year DSS and OS in each study group (all P < 0.001). Scheduled periodic PET/CT surveillance is a valuable tool for early detection of recurrent lesion(s) in asymptomatic OSCC patients who bear risk factors for disease recurrence. The presence of clinical symptoms and a short time to positive PET/CT findings were adverse prognostic factors for clinical outcome in patients with advanced OSCC. The priority of salvage therapy is discussed in each patient subgroup according to the devised prognostic scoring systems. (orig.)

    Purpose: Surgically resected melanoma patients with high-risk features commonly receive adjuvant therapy with interferon-alpha 2b combined with radiation therapy; the purpose of our study was to evaluate the potential enhancement of radiation toxicity by interferon. Methods and Materials: Patients at LDS Hospital and the University of Utah Medical Center in Salt Lake City treated with interferon during radiotherapy or within 1 month of its completion were retrospectively identified, and their charts were reviewed. If possible, the patients were asked to return to the LDS Hospital radiation therapy department for follow-up. Results: Five of 10 patients receiving interferon-alpha 2b therapy during radiation therapy or within 1 month of its completion experienced severe subacute/late complications of therapy. Severe subacute/late complications included two patients with peripheral neuropathy, one patient with radiation necrosis in the brain, and two patients with radiation necrosis in the s.c. tissue. One patient with peripheral neuropathy and one patient with radiation necrosis also developed lymphedema. Conclusions: In vitro studies have identified a radiosensitizing effect by interferon-alpha on certain cell lines, which suggests the possibility that patients treated with interferon and radiation therapy may experience more severe radiation toxicities. We have observed severe subacute/late complications in five of 10 patients treated with interferon-alpha 2b during radiation therapy or within 1 month of its completion. Although an observational study of 10 patients lacks the statistic power to reach conclusions regarding the safety and complication rates of combined interferon and radiation therapy, it is sufficient to raise concerns and suggest the need for prospective studies

    We designed this study to identify and suggest the reasonable timing of adjuvant radiotherapy in the treatment of uterine carcinosarcoma according to the surgical intent and patterns of progression. We retrospectively analyzed a total of 50 carcinosarcoma patients diagnosed between 1995 and 2010. Among these 50 patients, 32 underwent curative surgery and 13 underwent maximal tumor debulking surgery. The remaining five patients underwent biopsy only. Twenty-six patients received chemotherapy, and 15 patients received adjuvant radiotherapy. The median follow-up period was 17.3 months. Curative resection (p < 0.001) and stage (p < 0.001) were statistically significant factors affecting survival. During follow-up, 30 patients showed progression. Among these, eight patients (16.0%) had loco-regional progression only. The patients who had received adjuvant radiotherapy did not show loco-regional progression, and radiotherapy was a significant negative risk factor for loco-regional progression (p = 0.01). The time to loco-regional progression was much earlier for non-curative than curative resection (range, 0.7 to 7.6 months vs. 7.5 to 39.0 months). Adjuvant radiotherapy in the treatment of carcinosarcoma might be related to a low loco-regional progression rate. Radiotherapy should be considered in non-curatively resected patients as soon as possible.

    To assess the effects of adjuvant hormone therapy (AHT) on survival and disease outcome in women with epithelial ovarian cancer. Participants were premenopausal and postmenopausal women who had been diagnosed with epithelial ovarian cancer (any International Federation of Gynecology and Obstetrics stage) 9 or fewer months previously. Ineligible patients included those with deliberately preserved ovarian function, with a history of a hormone-dependent malignancy, or with any contraindications to hormone-replacement therapy. Patients were centrally randomly assigned in a 1:1 ratio to either AHT for 5 years after random assignment or no AHT (control). Main outcome measures were overall survival (OS), defined as time from random assignment to death (any cause), and relapse-free survival, defined as time from random assignment to relapse or death (any cause). Patients who continued, alive and relapse free, were censored at their last known follow-up. A total of 150 patients (n = 75, AHT; n = 75, control) were randomly assigned from 1990 to 1995 from 19 centers in the United Kingdom, Spain, and Hungary; all patients were included in intention-to-treat analyses. The median follow-up in alive patients is currently 19.1 years. Of the 75 patients with AHT, 53 (71%) have died compared with 68 (91%) of 75 patients in the control group. OS was significantly improved in patients who were receiving AHT (hazard ratio, 0.63; 95% CI, 0.44 to 0.90; P = .011). A similar effect was seen for relapse-free survival (hazard ratio, 0.67; 95% CI, 0.47 to 0.97; P = .032). Effects remained after adjustment for known prognostic factors. These results show that women who have severe menopausal symptoms after ovarian cancer treatment can safely take hormone-replacement therapy, and this may, in fact, infer benefits in terms of OS in addition to known advantages in terms of quality of life. © 2015 by American Society of Clinical Oncology.

  10. An Archaeosome-Adjuvanted Vaccine and Checkpoint Inhibitor Therapy Combination Significantly Enhances Protection from Murine Melanoma

    2017-10-01

    Full Text Available Archaeosomes constitute archaeal lipid vesicle vaccine adjuvants that evoke a strong CD8+ T cell response to antigenic cargo. Therapeutic treatment of murine B16-ovalbumin (B16-OVA melanoma with archaeosome-OVA eliminates small subcutaneous solid tumors; however, they eventually resurge despite an increased frequency of circulating and tumor infiltrating OVA-CD8+ T cells. Herein, a number of different approaches were evaluated to improve responses, including dose number, interval, and the combination of vaccine with checkpoint inhibitors. Firstly, we found that tumor protection could not be enhanced by repetitive and/or delayed boosting to maximize the CD8+ T cell number and/or phenotype. The in vivo cytotoxicity of vaccine-induced OVA-CD8+ T cells was impaired in tumor-bearing mice. Additionally, tumor-infiltrating OVA-CD8+ T cells had an increased expression of programmed cell death protein-1 (PD-1 compared to other organ compartments, suggesting impaired function. Combination therapy of tumor-bearing mice with the vaccine archaeosome-OVA, and α-CTLA-4 administered concurrently as well as α-PD-1 and an α-PD-L1 antibody administered starting 9 days after tumor challenge given on a Q3Dx4 schedule (days 9, 12, 15 and 18, significantly enhanced survival. Following multi-combination therapy ~70% of mice had rapid tumor recession, with no detectable tumor mass after >80 days in comparison to a median survival of 17–22 days for untreated or experimental groups receiving single therapies. Overall, archaeosomes offer a powerful platform for delivering cancer antigens when used in combination with checkpoint inhibitor immunotherapies.

    Purpose: Lymph node status is an important predictor of survival in pancreatic cancer. We performed a secondary analysis of Radiation Therapy Oncology Group (RTOG) 9704, an adjuvant chemotherapy and chemoradiation trial, to determine the influence of lymph node factors-number of positive nodes (NPN), total nodes examined (TNE), and lymph node ratio (LNR ratio of NPN to TNE)-on OS and disease-free survival (DFS). Patient and Methods: Eligible patients from RTOG 9704 form the basis of this secondary analysis of lymph node parameters. Actuarial estimates for OS and DFS were calculated using Kaplan-Meier methods. Cox proportional hazards models were performed to evaluate associations of NPN, TNE, and LNR with OS and DFS. Multivariate Cox proportional hazards models were also performed. Results: There were 538 patients enrolled in the RTOG 9704 trial. Of these, 445 patients were eligible with lymph nodes removed. Overall median NPN was 1 (min-max, 0-18). Increased NPN was associated with worse OS (HR = 1.06, p = 0.001) and DFS (HR = 1.05, p = 0.01). In multivariate analyses, both NPN and TNE were associated with OS and DFS. TNE > 12, and >15 were associated with increased OS for all patients, but not for node-negative patients (n = 142). Increased LNR was associated with worse OS (HR = 1.01, p < 0.0001) and DFS (HR = 1.006, p = 0.002). Conclusion: In patients who undergo surgical resection followed by adjuvant chemoradiation, TNE, NPN, and LNR are associated with OS and DFS. This secondary analysis of a prospective, cooperative group trial supports the influence of these lymph node parameters on outcomes after surgery and adjuvant therapy using contemporary techniques.

    Current guidelines recommend adjuvant chemotherapy for resected pancreatic adenocarcinoma (PDAC). However, no studies have addressed its survival benefit for stage I patients as they comprise IA or IB PDAC were identified. Median OS was 60.3 months (mo) for stage IA and 36.9 mo for IB. 45.5% received adjuvant chemotherapy; 19.9% received adjuvant chemoradiation. There was OS benefit for both stage IA/IB patients with adjuvant chemotherapy (HR = 0.73 and 0.76 for IA and IB, respectively, p = 0.002 and IA disease (n = 1,477, 37.8%), age ≥70 (p < 0.001), higher grade (p < 0.001), ≤10 lymph nodes examined (p = 0.008), positive margins (p < 0.001), and receipt of adjuvant chemoradiation (p = 0.002) were associated with worse OS. For stage IB patients (n = 2,432, 62.2%), similar associations were observed with the exception of adjuvant chemoradiation whereby there was no significant association (p = 0.35). Adjuvant chemotherapy was associated with an OS benefit for patients with stage I PDAC; adjuvant chemoradiation was either of no benefit or associated with worse OS.

    This study was conducted during the development of innovative treatment targeting the microenvironment of chondrosarcoma. In this context, MMP inhibitors were conjugated with a quaternary ammonium (QA) function as a targeting ligand to proteoglycans of chondrosarcoma extracellular matrix. Here we report the proof of concept of this strategy applied to the MMP13 inhibitor, doxycycline (Dox). A quaternary ammonium derivative of the MMP13 inhibitor doxycycline (QA-Dox) was synthesized, and its anticancer activity was evaluated in the Swarm rat chondrosarcoma (SRC) model compared with the parent drug doxycycline, in vitro and in vivo. In vivo, dox and QA-Dox efficiency was assessed at equimolar doses according to a q4dx4 schedule by monitoring tumour volume by MRI and PG-targeted scintigraphy. Molecular mechanism (MMP13 expression, proteoglycan level) and histology studies were performed on tumours. The link of QA targeting function to Dox maintained the MMP13 inhibitory activity in vitro. Interestingly, the bacteriostatic activity was lost. SRC cells incubated with both drugs were blocked in S and G2 M phases. Tumour growth inhibition (confirmed by histology) was observed for both Dox and QA-Dox. Undesirable blood effects (leukocyte decrease) were reduced when Dox was targeted to tumour tissue using the QA function. In the SRC model, the MMP13 inhibitor Dox and its QA derivative are promising as adjuvant therapies for chondrosarcoma management.

    The prevalence of morbid obesity is increasing rapidly. Weight reduction is very difficult using diet restriction and physical activity alone. Sibutramine has been shown to be effective and safe as an adjuvant therapy to diet restrictions. To describe our experience using sibutramine in weight reduction treatment of adolescents suffering from morbid obesity. The study group comprised 20 young persons (13 females, mean age 15 years 4 months, range 13-18 years) with morbid obesity (body mass index above the 95th percentile for age and/or > or =30 kg/m2) who were treated with sibutramine 10 mg once a day for 1 year. Mean BMI was 40 +/- 5.6 kg/m2 (range 30.1 - 49.5 kg/m2) at the beginning of treatment. Most patients showed an early weight reduction to mean BMI 39.3 +/- 4.9 and 35.9 +/- 5.7 at 3 and 6 months respectively, but stopped losing weight over the next 6 months. During the follow-up period 17 patients discontinued the treatment. The main reason for dropout was the slow rate of weight reduction after 6 months. Patients suffering from concomitant disorders (severe asthma, hypertension, sleep obstructive apnea) showed improvement after weight reduction. Adverse reactions from the treatment were transient, mild and well tolerated. Sibutramine may help in achieving weight reduction for a short period and in improving concomitant health problems, however its long-term effect is limited.

    Solitary uterine metastases from extragenital cancers are very rare. Breast cancer is the most frequent primary site of metastasis to the uterine corpus, with invasive lobular carcinoma more likely to spread to gynecologic organs than invasive ductal carcinoma. A 62-year-old postmenopausal Japanese woman was diagnosed with uterine leiomyomata more than 20 years ago and had been managed conservatively until menopause. Seven years prior to her presentation, she was diagnosed with breast cancer and underwent a partial resection of her right breast for stage IIA invasive lobular carcinoma. She underwent adjuvant chemotherapy, radiotherapy, and five years of anastrozole hormonal therapy. She presented with a growing uterine mass. Her tumor marker levels were markedly increased over the course of her follow-up, but a systemic examination revealed only a solitary uterine tumor. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. A histopathological examination, including detailed immunohistochemistry, confirmed metastatic invasive lobular carcinoma, infiltrating both her uterine myometrium and fibroid tissue. We report a very rare metastatic pattern of invasive lobular carcinoma and demonstrate that gross cystic disease fluid protein-15 and mammaglobin are useful in the diagnosis of metastatic breast cancer.

    Full Text Available We investigated the hypothesis that patients developing high-grade erythema of the breast skin during radiation treatment could be more likely to present increased levels of proinflammatory cytokines which may lead, in turn, to associated fatigue. Forty women with early stage breast cancer who received adjuvant radiotherapy were enrolled from 2007 to 2010. Fatigue symptoms, erythema, and cytokine levels (IL-1β, IL-2, IL6, IL-8, TNF-α, and MCP-1 were registered at baseline, during treatment, and after radiotherapy completion. Seven (17.5% patients presented fatigue without associated depression/anxiety. Grade ≥2 erythema was observed in 5 of these 7 patients. IL-1β, IL-2, IL-6, and TNF-α were statistically increased 4 weeks after radiotherapy (P<0.05. After the Heckman two-step analysis, a statistically significant influence of skin erythema on proinflammatory markers increase (P = 0.00001 was recorded; in the second step, these blood markers showed a significant impact on fatigue (P = 0.026. A seeming increase of fatigue, erythema, and proinflammatory markers was observed between the fourth and the fifth week of treatment followed by a decrease after RT. There were no significant effects of hormone therapy, breast volume, and anemia on fatigue. Our study seems to suggest that fatigue is related to high-grade breast skin erythema during radiotherapy through the increase of cytokines levels.

    Cancer cells, relative to normal cells, demonstrate significant alterations in metabolism that are proposed to result in increased steady-state levels of mitochondrial-derived reactive oxygen species (ROS) such as O2•−and H2O2. It has also been proposed that cancer cells increase glucose and hydroperoxide metabolism to compensate for increased levels of ROS. Given this theoretical construct, it is reasonable to propose that forcing cancer cells to use mitochondrial oxidative metabolism by feeding ketogenic diets that are high in fats and low in glucose and other carbohydrates, would selectively cause metabolic oxidative stress in cancer versus normal cells. Increased metabolic oxidative stress in cancer cells would in turn be predicted to selectively sensitize cancer cells to conventional radiation and chemotherapies. This review summarizes the evidence supporting the hypothesis that ketogenic diets may be safely used as an adjuvant therapy to conventional radiation and chemotherapies and discusses the proposed mechanisms by which ketogenic diets may enhance cancer cell therapeutic responses.

    The successful translation of the scientific principles of targeting the breast tumour oestrogen receptor (ER) with the nonsteroidal anti-oestrogen tamoxifen and using extended durations (at least 5 years) of adjuvant therapy, dramatically increased patient survivorship and significantly enhanced a drop in national mortality rates from breast cancer. The principles are the same for the validation of aromatase inhibitors to treat post-menopausal patients but tamoxifen remains a cheap, life-saving medicine for the pre-menopausal patient. Results from the Oxford Overview Analysis illustrate the scientific principle of "longer is better" for adjuvant therapy in pre-menopausal patients. One year of adjuvant therapy is ineffective at preventing disease recurrence or reducing mortality, whereas five years of adjuvant tamoxifen reduces recurrence by 50% which is maintained for a further ten years after treatment stops. Mortality is reduced but the magnitude continues to increase to 30% over a 15-year period. With this clinical database, it is now possible to implement simple solutions to enhance survivorship. Compliance with long-term anti-hormone adjuvant therapy is critical. In this regard, the use of selective serotonin reuptake inhibitors (SSRIs) to reduce severe menopausal side effects may be inappropriate. It is known that SSRIs block the CYP2D6 enzyme that metabolically activates tamoxifen to its potent anti-oestrogenic metabolite, endoxifen. The selective norepinephrine reuptake inhibitor, venlafaxine, does not block CYP2D6, and may be a better choice. Nevertheless, even with perfect compliance, the relentless drive of the breast cancer cell to acquire resistance to therapy persists. The clinical application of long-term anti-hormonal therapy for the early treatment and prevention of breast cancer, focused laboratory research on the discovery of mechanisms involved in acquired anti-hormone resistance.

    Purpose: To report outcomes for patients with resected pancreas cancer treated with an adjuvant regimen consisting of gemcitabine-based combination chemotherapy followed by capecitabine and radiation. Patients and Methods: We performed a retrospective review of a series of patients treated at a single institution with a common postoperative adjuvant program. Between January 2002 and August 2006, 43 resected pancreas cancer patients were offered treatment consisting of 4, 21-day cycles of gemcitabine 1 g/m 2 intravenously over 30 min on Days 1 and 8, with either cisplatin 35 mg/m 2 intravenously on Days 1 and 8 or capecitabine 1500 mg/m 2 orally in divided doses on Days 1-14. After completion of combination chemotherapy, patients received a course of radiotherapy (54 Gy) with concurrent capecitabine (1330 mg/m 2 orally in divided doses) day 1 to treatment completion. Results: Forty-one patients were treated. Median progression-free survival for the entire group was 21.7 months (95% confidence interval 13.9-34.5 months), and median overall survival was 45.9 months. In multivariate analysis a postoperative CA 19-9 level of ≥180 U/mL predicted relapse and death. Toxicity was mild, with only two hospitalizations during adjuvant therapy. Conclusions: A postoperative adjuvant program using combination chemotherapy with gemcitabine and either cisplatin or capecitabine followed by radiotherapy with capecitabine is tolerable and efficacious and should be considered for Phase III testing in this group of patients.

    Purpose: Local-regional failures (LFs) after cystectomy with or without chemotherapy are common in locally advanced disease. Adjuvant radiation therapy (RT) could reduce LFs, but toxicity has discouraged its use. Modern RT techniques with improved normal tissue sparing have rekindled interest but require knowledge of pelvic failure patterns to design treatment volumes. Methods and Materials: Five-year LF rates after radical cystectomy plus pelvic node dissection with or without chemotherapy were determined for 8 pelvic sites among 442 urothelial bladder carcinoma patients. The impact of pathologic stage, margin status, nodal involvement, and extent of node dissection on failure patterns was assessed using competing risk analysis. We calculated the percentage of patients whose sites of LF would have been completely encompassed within various hypothetical clinical target volumes (CTVs) for postoperative radiation. Results: Compared with stage ≤pT2, stage ≥pT3 patients had higher 5-year LF rates in virtually all pelvic sites. Among stage ≥pT3 patients, margin status significantly altered the failure pattern whereas extent of node dissection and nodal positivity did not. In stage ≥pT3 patients with negative margins, failure occurred predominantly in the iliac/obturator nodes and uncommonly in the cystectomy bed and/or presacral nodes. Of these patients in whom failure subsequently occurred, 76% would have had all LF sites encompassed within CTVs covering only the iliac/obturator nodes. In stage ≥pT3 with positive margins, cystectomy bed and/or presacral nodal failures increased significantly. Only 57% of such patients had all LF sites within CTVs limited to the iliac/obturator nodes, but including the cystectomy bed and presacral nodes in the CTV when margins were positive increased the percentage of LFs encompassed to 91%. Conclusions: Patterns of failure within the pelvis are summarized to facilitate design of adjuvant RT protocols. These data suggest that

    Purpose: Although chemoradiotherapy was considered the standard adjuvant treatment for gastric cancer, a recent Phase III trial (Medical Research Council Adjuvant Gastric Infusional Chemotherapy [MAGIC]) did not include radiotherapy in the randomization scheme because it was considered expendable. Given radiotherapy's potential, efforts needed to be made to optimize its use for treating gastric cancer. We assessed whether intensity-modulated radiotherapy (IMRT) could improve upon our published results in patients treated with three-dimensional (3D) conformal therapy. Methods and Materials: Fourteen patients with adenocarcinoma of the stomach were treated with adjuvant chemoradiotherapy using a noncoplanar four-field arrangement. Subsequently, a nine-field IMRT plan was designed using a CMS Xio IMRT version 4.3.3 module. Two IMRT beam arrangements were evaluated: beam arrangement 1 consisted of gantry angles of 0 deg., 53 deg., 107 deg., 158 deg., 204 deg., 255 deg., and 306 deg.. Beam arrangement 2 consisted of gantry angles of 30 deg., 90 deg., 315 deg., and 345 deg.; a gantry angle of 320 deg./couch, 30 deg.; and a gantry angle of 35 o /couch, 312 o . Both the target volume coverage and the dose deposition in adjacent critical organs were assessed in the plans. Dose-volume histograms were generated for the clinical target volume, kidneys, spine, and liver. Results: Comparison of the clinical target volumes revealed satisfactory coverage by the 95% isodose envelope using either IMRT or 3D conformal therapy. However, IMRT was only marginally better than 3D conformal therapy at protecting the spine and kidneys from radiation. Conclusions: IMRT confers only a marginal benefit in the adjuvant treatment of gastric cancer and should be used only in the small subset of patients with risk factors for kidney disease or those with a preexisting nephropathy.

    The effectiveness of exercise therapy in the treatment of osteoarthritis of the knee (KOA) is widely evidenced. The current study aims to compare the effectiveness of massage therapy as a co-adjuvant treatment for KOA. A blind, randomized controlled trial design was used. Eighteen women were randomly allocated to two different groups. Group A was treated with massage therapy and an exercise program, and Group B was treated with the exercise program alone. The intervention lasted for 6 weeks. Outcomes were assessed using a verbal analogue scale (VAS), the WOMAC index, and the Get-Up and Go test. Baseline, post-treatment, and 1- and 3- month follow-up data were collected. Values were considered statistically significant at a p massage therapy may lead to clinical improvement in patients with KOA. The use of massage therapy combined with exercise as a treatment for gonarthrosis does not seem to have any beneficial effects.

    Full Text Available Objective: To discuss the effect of adjuvant levosimendan therapy on neuroendocrine hormones and cytokines in elderly patients with chronic heart failure. Methods: A total of 100 elderly patients with chronic heart failure who were treated in the hospital between March 2014 and March 2017 were divided into control group and levosimendan group by random number table, each with 50 cases. Control group received clinical routine therapy for chronic heart failure, and levosimendan group received routine therapy combined with adjuvant levosimendan therapy. The differences in serum levels of RAAS indexes, thyroid hormones, myocardial damage indexes and endothelial function indexes were compared between the two groups before and after treatment. Results: At T0, there was no statistically significant difference in serum levels of RAAS indexes, thyroid hormones, myocardial damage indexes and endothelial function indexes between the two groups. At T1, serum RAAS indexes PRA, AngⅡ and ALD levels of levosimendan group were lower than those of control group; serum thyroid hormones TT3, TT4, FT3 and FT4 levels of levosimendan group were higher than those of control group; serum myocardial damage indexes cTnⅠ, H-FABP and NT-proBNP levels of levosimendan group were lower than those of control group; serum endothelial function index NO level of levosimendan group was higher than that of control group while ET-1 level was lower than that of control group. Conclusion: Adjuvant levosimendan therapy for elderly patients with chronic heart failure can effectively adjust the secretion of neuroendocrine hormones and reduce the myocardial and vascular endothelial damage.

    Down syndrome (DS) has characteristics that include mental retardation, a characteristic phenotype, congenital heart defects, immune disorders, and increased risk of periodontal disease (PD). Antimicrobial photodynamic therapy (aPDT) is the combined use of photosensitizers associated with low-level laser (LLL) and oxygen, leading to singlet oxygen formation, which contributes to the antibacterial activity of the phagocytes, killing bacteria. The objective of this study was to evaluate the efficacy of aPDT as an adjuvant to conventional periodontal treatment of PD in DS patients. A double-blinded, controlled, randomized, split-mouth study was conducted. A total of 13 DS subjects who were 18 years or older and who presented at least one tooth in each quadrant of the mouth with probing pocket depth (PPD) equal to or greater than 5 mm were included. The patients were evaluated at three different times: at the baseline, PPD were obtained. After 1 week, conventional scaling and root planing (SRP) was performed, and two randomly selected quadrants also received aPDT. One month after SRP, all the patients were reevaluated. Periodontal conditions were improved among all the participants. The PDT-with-SRP group presented a nonsignificant reduction in PPD (mean = 1.27 mm, median = 1.17 mm) relative to that of the SRP group (mean = 1.00 mm, median = 0.95 mm). Changes over time were compared using the Wilcoxon test. A significant reduction in median PPD was observed in both groups (p = 0.001). Both types of periodontal treatment, with and without PDT, were similarly effective and were associated with good clinical response.

    Full Text Available Ca(2+-loaded calmodulin normally inhibits multiple Ca(2+-channels upon dangerous elevation of intracellular Ca(2+ and protects cells from Ca(2+-cytotoxicity, so blocking of calmodulin should theoretically lead to uncontrolled elevation of intracellular Ca(2+. Paradoxically, classical anti-psychotic, anti-calmodulin drugs were noted here to inhibit Ca(2+-uptake via the vanilloid inducible Ca(2+-channel/inflamatory pain receptor 1 (TRPV1, which suggests that calmodulin inhibitors may block pore formation and Ca(2+ entry. Functional assays on TRPV1 expressing cells support direct, dose-dependent inhibition of vanilloid-induced (45Ca(2+-uptake at microM concentrations: calmidazolium (broad range > or = trifluoperazine (narrow range chlorpromazine/amitriptyline>fluphenazine>>W-7 and W-13 (only partially. Most likely a short acidic domain at the pore loop of the channel orifice functions as binding site either for Ca(2+ or anti-calmodulin drugs. Camstatin, a selective peptide blocker of calmodulin, inhibits vanilloid-induced Ca(2+-uptake in intact TRPV1(+ cells, and suggests an extracellular site of inhibition. TRPV1(+, inflammatory pain-conferring nociceptive neurons from sensory ganglia, were blocked by various anti-psychotic and anti-calmodulin drugs. Among them, calmidazolium, the most effective calmodulin agonist, blocked Ca(2+-entry by a non-competitive kinetics, affecting the TRPV1 at a different site than the vanilloid binding pocket. Data suggest that various calmodulin antagonists dock to an extracellular site, not found in other Ca(2+-channels. Calmodulin antagonist-evoked inhibition of TRPV1 and NMDA receptors/Ca(2+-channels was validated by microiontophoresis of calmidazolium to laminectomised rat monitored with extracellular single unit recordings in vivo. These unexpected findings may explain empirically noted efficacy of clinical pain adjuvant therapy that justify efforts to develop hits into painkillers, selective to sensory Ca(2

    The benefit of adjuvant therapy (AT) for gallbladder cancer (GBC) is unclear as evidenced by conflicting results from nonrandomized studies. Here we aimed to perform a meta-analysis to determine the impact of AT on overall survival (OS). We used data from MEDLINE, EMBASE and the Cochrane Collaboration Library and published between October 1967 and October 2014. Studies that evaluated AT compared with curative-intent surgery alone for resected GBC were included. Subgroup analyses of benefit based on node status, margins status, and American Joint Committee on Cancer (AJCC) staging were prespecified. Data were weighted and pooled using random-effect modeling. Ten retrospective studies involving 3,191 patients were analyzed. There was a nonsignificant improvement in OS with AT compared with surgery alone (hazard ratio [HR], 0.76; 95 % confidence interval [CI], 0.56–1.03). A significant improvement was observed in OS with chemotherapy (CT) compared with surgery alone (HR, 0.42; 95 % CI, 0.22–0.80) by sensitivity analysis. The greatest benefit for AT was also observed in those with R1 disease (HR, 0.33; 95 % CI, 0.19–0.59), LN-positive disease (HR, 0.71; 95 % CI, 0.63–0.81), and AJCC staging meeting or exceeding tumor Stage II (HR, 0.45; 95 % CI, 0.26–0.79), but not in those with LN-negative or R0 disease. Our results strongly support the use of CT as an AT in GBC. Moreover, patients with node positivity, margin positivity, or non-stage I disease are more likely to benefit from AT

    It is unknown what minimal benefit in disease-free survival older patients with breast cancer require from adjuvant systemic therapy, and if this differs from that required by younger patients. We prospectively examined patients' preferences for adjuvant chemotherapy (aCT) and adjuvant hormonal therapy (aHT), factors related to minimally-required benefit, and patients' self-reported motivations. Fifty-two younger (40-64 years) and 29 older (≥ 65 years) women with a first primary, invasive tumor were interviewed post-surgery, prior to receiving aCT/aHT recommendation. The proportions of younger versus older participants who would accept, refuse, or were undecided about therapy were 92% versus 62%, 4% versus 24%, and 4% versus 14% for aCT, and 92% versus 59%, 8% versus 17%, and 0% versus 24% for aHT. The proportion of older participants who would refuse rather than accept aCT was larger than that of younger participants (P = .005). No significant difference was found for aHT (P = .12). Younger and older participants' minimally-required benefit, in terms of additional 10-year disease-free survival, to accept aCT (median, 5% vs. 4%; P = .13) or aHT (median, 10% vs. 8%; P = .15) did not differ. Being single/divorced/widowed (odds ratio [OR], 0.16; P = .005), presence of geriatric condition (inability to perform daily activities, incontinence, severe sensory impairment, depression, polypharmacy, difficulties with walking; OR, 0.27; P = .047), and having a preference to make the treatment decision either alone or after considering the clinician's opinion (active role; OR, 0.15; P = .012) were independently related to requiring larger benefits from aCT. The most frequent motivations for/against therapy included the wish to survive/avoid recurrence, clinician's recommendation, side effects, and treatment duration (only aHT). Whereas older participants were less willing to accept aCT than younger participants, no significant difference was found for aHT. However, a

    Full Text Available Abstract Background Major depressive disorder is among the medical conditions with the highest negative impact on work outcome. However, little is known regarding evidence-based interventions targeting the improvement of work outcomes in depressed employees. In this paper, the design of a randomized controlled trial is presented in order to evaluate the effectiveness of adjuvant occupational therapy in employees with depression. This occupational intervention is based on an earlier intervention, which was designed and proven effective by our research group, and is the only intervention to date that specifically targets work outcome in depressed employees. Methods/Design In a two-arm randomized controlled trial, a total of 117 participants are randomized to either 'care as usual' or ' care as usual' with the addition of occupational therapy. Patients included in the study are employees who are absent from work due to depression for at least 25% of their contract hours, and who have a possibility of returning to their own or a new job. The occupational intervention consists of six individual sessions, eight group sessions and a work-place visit over a 16-week period. By increasing exposure to the working environment, and by stimulating communication between employer and employee, the occupational intervention aims to enhance self-efficacy and the acquisition of more adaptive coping strategies. Assessments take place at baseline, and at 6, 12, and 18-month follow-ups. Primary outcome measure is work participation (hours of absenteeism and time until work resumption. Secondary outcome measures are work functioning, symptomatology, health-related quality of life, and neurocognitive functioning. In addition, cost-effectiveness is evaluated from a societal perspective. Finally, mechanisms of change (intermediate outcomes and potential patient-treatment matching variables are investigated. Discussion This study hopes to provide valuable knowledge

    Full Text Available Chronic gastroduodenitis (CGD hold one of main places among leading diseases of gastro-intestinal tract (GIT in childhood. A special category is children who have CGD against the background of connective tissue (CT dysplasia (DCT. CGD in such children is characterized by early appearance, aggressive, gradient course with frequent acute conditions and recurrences with evident symptoms of nonspecific intoxication manifestations. Defect of collagen synthesis leads to pronounced morphological changes of proximal GIT mucous membrane (MM and decline in its cytoptotecive abilities. Challenges related to the qualitative and quantitative local ecosystem changes can aggravate immune and metabolic local processes and enhance the destruction of proximal GIT mucous membrane. Aforesaid defines the need to include multiprobiotics into the treatment schemes of patient with CGD, associated with congenital fibrogenesis disorders, as adjuvant therapy with complex therapeutic action; they positively influence the CT metabolism, improve reparative processes in MM, normalize immune processes and maintain composition and functions of physiological microbiota. Purposes – improvement of CGD treatment efficiency in children with DCT through inclusion of the multiprobiotic Symbiter® forte-M into the treatment schemes. Materials and methods. There were examined 33 children with CGD on the background of DCT and 32 healthy children (control from 11 to 17 years old. The state of the mucous barrier was estimated by certain mucin constituents (fucose, glycosaminoglycans, sialic acids assessing, antimicrobial peptides (ß2-defencins, non-specific humoral factors of the local immunity (immunoglobulins, lysozyme in mucous secretions (saliva, coprofiltrate (CF before and after probiotic therapy.

This study aimed to explore factors that influence adherence and nonadherence to AET following breast cancer to inform the development of supportive interventions.Methods: Interviews were conducted with 32 women who had been prescribed AET, 2–4 years following their diagnosis of breast cancer. Both adherers (n=19 and nonadherers (n=13 were recruited. The analysis was conducted using the Framework approach.Results: Factors associated with adherence were as follows: managing side effects including information and advice on side effects and taking control of side effects, supportive relationships, and personal influences. Factors associated with nonadherence were as follows: burden of side effects, feeling unsupported, concerns about long-term AET use, regaining normality, including valuing the quality of life over length of life, and risk perception.Conclusion: Provision of timely information to prepare women for the potential side effects of AET and education on medication management strategies are needed, including provision of timely and

    Epidermal growth factor receptor (EGFR) mutations occur in up to 50% of Asian patients with non-small cell lung cancer (NSCLC). Treatment of advanced NSCLC patients with EGFR-tyrosine kinase inhibitor (EGFR-TKI) confers a significant survival benefit. This study assessed the efficacy and safety of chemotherapy with or without icotinib in patients undergoing resection of stage IB to ⅢA EGFR-mutated NSCLC. Patients with surgically resected stage IB (with high risk factors) to ⅢA EGFR-mutated NSCLC were randomly assigned (1:1) to one of two treatment plans. One group received four cycles of platinum-based doublet chemotherapy every three weeks, and the other group received platinum-based chemotherapy supplemented with consolidation therapy of orally administered icotinib (125 mg thrice daily) two weeks after chemotherapy. The icotinib treatment continued for four to eight months, or until the occurrence of disease relapse, metastasis or unacceptable icotinib or chemotherapy toxicity. The primary endpoint was disease-free survival (DFS). 41 patients were enrolled between Feb 9, 2011 and Dec 17, 2012. 21 patients were assigned to the combined chemotherapy plus icotinib treatment group, while 20 patients received chemotherapy only. DFS at 12 months was 100% for icotinib-treated patients and 88.9% for chemotherapy-only patients (p = 0. 122). At 18 months DFS for icotinib-treated vs. chemotherapy-only patients was 95.2% vs. 83.3% (p = 0. 225), respectively, and at 24 months DFS was 90.5% vs. 66.7% (p = 0. 066). The adverse chemotherapy effects predominantly presented as gastrointestinal reactions and marrow suppression, and there was no significant difference between the two treatment groups. Patients in the chemotherapy plus icotinib treatment group showed favorable tolerance to oral icotinib. The results suggest that chemotherapy plus orally icotinib displayed better DFS compared with chemotherapy only, yet the difference in DFS was not significant. We would think

    One hundred women treated for carcinoma of the cervix were interviewed more than one year later to establish the effects of radiation or surgical therapy on sexual function. Forty-three had received irradiation, 44 nonradical surgery, six combined surgery and irradiation, and seven radical surgery. The irradiation and nonradical surgery groups were each further subdivided into subgroups of patients aged 30 to 49 for age-controlled comparison. Patients in the irradiation group had statistically significant decreases in sexual enjoyment, ability to attain orgasm, coital opportunity, frequency of intercourse, and coital desire. The group who had nonradical surgical procedures had no significant change in sexual function after treatment. Similar results were found in both age-controlled subgroups, eliminating age as a major etiologic factor. Marked vaginal alterations were recorded in the majority of irradiated patients, but were not present among the groups treated with nonradical surgery. The vaginal changes alone could not be held accountable for the significant decrease in sexual function among women who received pelvic irradiation. The origin of decreased sexual desire after radiation therapy is complex, and not yet completely understood.

    Postoperative radiation therapy (PORT) and postoperative chemotherapy (POCT) can be administered as adjuvant therapies in patients with non-small cell lung cancer (NSCLC). The aim of this study was to present the clinical outcomes in patients treated with PORT-first with or without subsequent POCT in stage IIIA-N2 NSCLC. From January 2002 to November 2014, the conditions of 105 patients with stage IIIA-N2 NSCLC who received PORT-first with or without subsequent POCT were analyzed. PORT was initiated within 4 to 6 weeks after surgical resection. Platinum-based POCT was administered 3 to 4 weeks after the completion of PORT. We analyzed the outcomes and the clinical factors affecting survival. Of 105 patients, 43 (41.0%) received POCT with a median of 4 cycles (range, 2-6 cycles). The follow-up times ranged from 3 to 123 months (median, 30 months), and the 5-year overall survival (OS) was 40.2%. The 5-year OS of patients treated with PORT and POCT was significantly higher than that of patients with PORT (61.3% vs 29.2%, Ptreatment of stage IIIA-N2 NSCLC. The benefit of POCT on OS was preserved even in the PORT-first setting. Further studies are warranted to compare the sequencing of PORT and POCT, guaranteeing the proper use of POCT.

    Full Text Available Objective: To analyze the effect of probucol combined with atorvastatin adjuvant therapy on serum indexes of acute cerebral infarction patients in rehabilitation period. Methods: A total of 102 patients with acute cerebral infarction were treated in our hospital from August 2011 to June 2015, were confirmed by magnetic resonance imaging and were randomly divided into observation group 51 cases and control group 51 cases according to the order of hospitalization. Control group received atorvastatin treatment alone, observation group received probucol combined with atorvastatin adjuvant therapy, and then differences in levels of serum CXCL16, HMGB1, CD40L and Fibulin-5, P-selectin, NPY, CGRP, visfatin and others, chemokines and inflammation-related factors, vascular endothelial cells and fibrinolytic function, etc were compared between two groups after treatment. Results: Serum CXCL16, HMGB1, CD40L and Fibulin-5 levels of observation group after treatment were lower than those of control group; serum P-selectin, NPY, visfatin, UCH-L1, sVCAM-1 and SAA levels of observation group after treatment were lower than those of control group while CGRP level was higher than that of control group; serum CCL-19, CCL-21, YKL-40, IL-33 and IL- 18 values of observation group after treatment were lower than those of control group; serum vWF, PAI-1 and plasminogen levels of observation group after treatment were lower than those of control group while 6-K-PGF1α and tPA levels were higher than those of control group. Conclusions: Probucol combined with atorvastatin adjuvant therapy for acute cerebral infarction patients in rehabilitation period can effectively optimize patients’ general status and avoid re-infarction in recovery period, and it has positive clinical significance.

    Introduction There remains a lack of high quality randomised trial evidence for the use of adjuvant chemotherapy in stage II rectal cancer, particularly in the presence of high risk features such as extramural venous invasion (EMVI). The aim of this study was to explore this issue through a survey of colorectal surgeons and gastrointestinal oncologists. Methods An electronic survey was sent to a group of colorectal surgeons who were members of the Association of Coloproctology of Great Britain and Ireland. The survey was also sent to a group of gastrointestinal oncologists through the Pelican Cancer Foundation. Reminder emails were sent at 4 and 12 weeks. Results A total of 142 surgeons (54% response rate) and 99 oncologists (68% response rate) responded to the survey. The majority in both groups of clinicians thought EMVI was an important consideration in adjuvant treatment decision making and commented routinely on this in their multidisciplinary team meeting. Although both would consider treating patients on the basis of EMVI detected by magnetic resonance imaging, oncologists were more selective. Both surgeons and oncologists were prepared to offer patients with EMVI adjuvant chemotherapy but there was lack of consensus on the benefit. Conclusions This survey reinforces the evolution in thinking with regard to adjuvant therapy in stage II disease. Factors such as EMVI should be given due consideration and the prognostic information we offer patients must be more accurate. Historical data may not accurately reflect today’s practice and it may be time to consider an appropriately designed trial to address this contentious issue. PMID:25245736

    Matrix metalloproteinases (MMPs) are important enzymes in tissue turnover and various inflammatory processes. In this study, it was evaluated whether serum MMP-8 can predict the response to adjuvant interferon alfa-2b (IFN-α) therapy in patients with operated high-risk cutaneous melanoma. Pre......-treatment sera from 460 patients with stage IIB-IIIC melanoma were analyzed for MMP-8. The patients were randomized after surgery to adjuvant IFN-α for 12 or 24 months (n = 313) or observation only (n = 147). The median serum MMP-8 level was used to classify the patients into a low MMP-8 (n = 232) and a high MMP......-8 (n = 228) group. In the high MMP-8 subgroup, IFN-α therapy significantly improved relapse-free survival (RFS). RFS was 36.8 months in patients with high MMP-8 levels receiving IFN-α therapy, whereas RFS for those with high MMP-8 levels with observation only was 10.6 months (P = 0.027). Median...

    Our purpose as to evaluate the impact of adjuvant radioactive iodine therapy (RAI) on prognosis, as assessed by progression-free survival (PFS) and overall survival (OS), in patients affected by differentiated thyroid carcinoma (DTC) lymph-node relapse and previously treated with lymphadenectomy. We retrospectively evaluated DTC patients treated with lymph-node dissection for disease relapse. All patients had previously undergone total thyroidectomy and radioiodine remnant ablation (RRA). We used clinical and histological data obtained during follow-up to assess response and outcome. By means of univariate and multivariate time-to-event analyses, we assessed the impact of RAI on outcome (PFS and OS) and the prognostic role of thyroglobulin (Tg) levels under suppression with levothyroxine (Tg-on) measured 1-3 months after lymphadenectomy and of other risk factors. We evaluated 113 patients (age at diagnosis: median 41 years, interquartile range: 31-59), 64 of whom were treated with RAI. Over a median follow-up time of 5.7 years, 27 patients showed disease progression and 13 died. Kaplan-Meier PFS and OS curves showed that age on diagnosis, tumor histology, tumor size, DTC aggressive variant, and Tg-on were associated with prognosis. Patients with Tg-on ≥1 ng/ml treated with RAI showed a better PFS (Log-rank pp 0.001) and OS (p = 0.005) than untreated patients, while no effect of RAI was observed in patients with Tg-on <1 ng/ml. Multivariate models showed that age, Tg-on (≥1 vs. < 1 ng/ml, HR: 18.2, 95% CI: 5.09-64.8, p = 0.001) and RAI (Yes vs. No, HR: 0.36,95%CI: 0.15-0. 9, p = 0.02) remained the only independent factors associated with PFS, but only age and Tg-on remained significantly associated with OS (HR: 8.31, 95%CI:1.56-44.3, p = 0.01). Nonetheless, patients treated with RAI showed a lower risk of mortality (HR: 0.34, 95%CI: 0.1-1.15 p = 0.08) than untreated patients. RAI after lymphadenectomy for DTC relapse is significantly associated with better PFS

    To assess the outcome of surgical therapy and choice of surgical strategy for patients with adenocarcinoma of the gastroesophageal junction. Between February 1989 and January 2005 during 16 years, 335 patients (65 female, 270 male, mean age 56 years) with esophagogastric junction adenocarcinoma underwent surgical operation. The choice of surgical approach was based on the anatomical location of the tumor mass. Outcome of surgery, histopathologic characteristics, demographic data and long term survival rates were compared among three types of tumor defined as follows. Type I: Adenocarcinoma of the distal esophagus which infiltrates the esophagogastric junction from above. Type II: True carcinoma of the cardia arising immediately at the esophagogastric junction. Type III: Subcardial gastric carcinoma that infiltrates the esophagogastric junction and distal esophagus from below. Of the 335 patients undergoing resection, 110 (33%) had type I, 96 (28%) had type II, and 129 (39%) had type III. The preponderance of the male sex and the prevalence of metaplasia in distal esophagus decreased from type I to type III tumors (P<0.01). The prevalence of undifferentiated tumors increased from type I to type III tumors (P<0.01). Esophagectomy with resection of the proximal stomach for type I and extended total gastrectomy with transhiatal resection of the distal esophagus for type II and III were the primary procedures. The mean number of removed lymph node was higher in type III and II compared to type I tumors. The overall postoperative 30-day mortality was 8.4%. The death rate in transthoracic esophagectomy was higher than with extended total gastrectomy. The classification of adenocarcinoma of the esophagogastric junction into type I, II and III tumors helps in the selection of surgical approach. Type I tumors are approached as distal esophageal cancer. Type III tumors are a special form of gastric cancer and treated as a gastric cancer. The relation of type II tumors to

    The clinical appearance of septic disorders is characterized by an enormous dynamic. The sepsis-induced dysbalance of the immune system necessitates immediate and aggressive therapeutic interventions to prevent further damage progression of the disease to septic shock and multiple organ failure. This includes supportive therapy to normalize and maintain organ and tissue perfusion as well as the identification of the infection focus. In cases where an infectious focus is identified, surgical source control frequently is a key element of the treatment strategy besides pharmacologic and supportive measures. The integrative approach of the management of septic patients requires rapid communication between the involved medical disciplines and the nursing personnel. Therefore, this article outlines current therapeutic concepts of septic diseases as well as central nursing aspects.

    Palliative treatment concepts are considered in patients with non-curatively resectable and/or metastasized pancreatic cancer. However, patients without metastases, but presented with marginally resectable or locally non-resectable tumors should not be treated by a palliative therapeutic approach. These patients should be enrolled in neoadjuvant radiochemotherapy trials because a potentially curative resection can be achieved in approximately one-third of them after finishing treatment and restaging. Within the scope of best possible palliative care, resection of the primary cancer together with excision of metastases represents a therapeutic option to be contemplated in selected cases. Comprehensive palliative therapy is based on treatment of bile duct or duodenal obstruction for certain locally unresectable or metastasized advanced pancreatic cancer. However, endoscopic or percutaneous stenting procedures and surgical bypass provide safe and highly effective therapeutic alternatives. In case of operative drainage of the biliary tract (biliodigestive anastomosis), the prophylactic creation of a gastro-intestinal bypass (double bypass) is recommended. The decision to perform a surgical versus an endoscopic procedure for palliation depends to a great extent on the tumor stage and the estimated prognosis, and should be determined by an interdisciplinary team for each patient individually

    There is general consensus that surgery gives a better intraocular pressure (IOP) control than medical therapy, but surgery may be affected by complications and failures, and for this reason nowadays, it is reserved to advanced or clearly progressive glaucoma. In recent years, there have been a lot of efforts to enhance safety and efficacy of conventional surgery as to find new techniques more safer and more effective. Actually, this is a field in rapid evolution, and we have a great number of innovative procedures, often working on complete different basis. These procedures are classified according to their mechanism of action and the type of surgical approach, in order to clearly understand of what we are speaking about. From a general point of view, surgical procedures may be divided in procedures that increase outflow and procedures that reduce aqueous production: most of these procedures can be performed with an ab externo or an ab interno approach. The ab interno approach has great advantages and enormous potential of development; probably, its diffusion will be facilitated by the development of new devices for angle visualization. Nevertheless, it is important to remember that actually none of the new procedures has been validated in large controlled clinical trials and none of the new procedures is indicated when IOP target is very low. © 2015 Elsevier B.V.

    Hemangioma is a mesenchymal benign tumor formed by blood vessels. Anomalies affect up to 10% of children and they are more common in females than in males. The aim of our study was to compare the treatment efficacy, namely the curative effect and adverse events, such as loss of pigment and appearance of scarring, between classical surgery techniques and laser techniques. For that reason a group of 223 patients with hemangioma was retrospectively reviewed. For treatment, a pulsed dye laser (PDL) (Rhodamine G, wavelength 595 nm, pulsewidth between 0.45 and 40 ms, spot diameter 7 mm, energy density 9-11 J cm-2) was used and the results were compared with a control group treated with classical surgical therapy under general anesthesia. The curative effects, mainly number of sessions, appearance of scars, loss of pigment, and relapses were evaluated as a marker of successful treatment. From the results it was evident that the therapeutic effects of both systems are similar. The PDL was successful in all cases. The surgery patients had four relapses. Classical surgery is directly connected with the presence of scars, but the system is safe for larger hemangiomas. It was confirmed that the PDL had the optimal curative effect without scars for small lesions (approximately 10 mm). Surgical treatment under general anesthesia is better for large hemangiomas; the disadvantage is the presence of scars.

  12. Tumor metabolism, the ketogenic diet and β-hydroxybutyrate: novel approaches to adjuvant brain tumor therapy

    2016-11-01

    Full Text Available Malignant brain tumors are devastating despite aggressive treatments such as surgical resection, chemotherapy and radiation therapy. The average life expectancy of patients with newly diagnosed glioblastoma is approximately ~18 months. It is clear that increased survival of brain tumor patients requires the design of new therapeutic modalities, especially those that enhance currently available treatments and/or limit tumor growth. One novel therapeutic arena is the metabolic dysregulation that results in an increased need for glucose in tumor cells. This phenomenon suggests that a reduction in tumor growth could be achieved by decreasing glucose availability, which can be accomplished through pharmacological means or through the use of a high-fat, low-carbohydrate ketogenic diet (KD. The KD, as the name implies, also provides increased blood ketones to support the energy needs of normal tissues. Preclinical work from a number of laboratories has shown that the KD does indeed reduce tumor growth in vivo. In addition, the KD has been shown to reduce angiogenesis, inflammation, peri-tumoral edema, migration and invasion. Furthermore, this diet can enhance the activity of radiation and chemotherapy in a mouse model of glioma, thus increasing survival. Additional studies in vitro have indicated that increasing ketones such as β-hydroxybutyrate in the absence of glucose reduction can also inhibit cell growth and potentiate the effects of chemotherapy and radiation. Thus, while we are only beginning to understand the pluripotent mechanisms through which the KD affects tumor growth and response to conventional therapies, the emerging data provide strong support for the use of a KD in the treatment of malignant gliomas. This has led to a limited number of clinical trials investigating the use of a KD in patients with primary and recurrent glioma.

    Background: Accurate tumour bed localisation is a key requirement for adjuvant radiotherapy. A new procedure is described for head and neck cancer treatment that improves tumour bed localisation using titanium clips. Materials and methods: Following complete local excision of the primary tumour, the tumour bed was marked with titanium clips. Preoperative gross target volume (GTV) and postoperative tumour bed were examined and the distances between the centres of gravity were evaluated. Results: 49 patients with squamous cell carcinoma of the oral cavity were prospectively enrolled in this study. All patients underwent tumour resection, neck lymph node dissection and defect reconstruction in one stage. During surgery, 7–49 clips were placed in the resection cavity. Surgical clip insertion was successful in 88% (n = 43). Clip identification and tumour bed delineation was successful in all 43 patients. The overall distance between the centres of gravity of the preoperative tumour extension to the tumour bed was 0.9 cm. A significant relationship between the preoperative tumour extension and the postoperative tumour bed volume could be demonstrated. Conclusion: We demonstrate a precise delineation of the former tumour cavity. Improvements in tumour bed delineation allow an increase of accuracy for adjuvant treatment

    Hu-antigen R (HuR) is an RNA-binding protein that regulates the stability, translation, and nucleus-to-cytoplasm translocation of messenger RNAs (mRNAs). The aim of this study was to investigate the prognostic significance of HuR in cholangiocarcinoma patients who received adjuvant gemcitabine-based chemotherapy (AGC) after surgical resection. Nuclear and cytoplasmic HuR expression was investigated immunohistochemically in 131 patients with resected cholangiocarcinoma, including 91 patients administered AGC and 40 patients who did not receive adjuvant chemotherapy. The correlation between HuR expression and survival was evaluated by statistical analysis. High nuclear and cytoplasmic HuR expression was observed in 67 (51%) and 45 (34%) patients, respectively. Cytoplasmic HuR expression was significantly associated with lymph node metastasis (p < 0.01), while high cytoplasmic HuR expression was significantly associated with poor disease-free survival [DFS] (p = 0.03) and overall survival [OS] (p = 0.001) in the 91 patients who received AGC, but not in the 40 patients who did not receive AGC (DFS p = 0.17; OS p = 0.07). In the multivariate analysis of patients who received AGC, high cytoplasmic HuR expression was an independent predictor of poor DFS (hazard ratio [HR] 1.77; p = 0.04) and OS (HR 2.09; p = 0.02). Nuclear HuR expression did not affect the survival of enrolled patients. High cytoplasmic HuR expression was closely associated with the efficacy of AGC in patients with cholangiocarcinoma. The current findings warrant further investigations to optimize adjuvant chemotherapy regimens for resectable cholangiocarcinoma.

  15. Inducers of Senescence, Toxic Compounds, and Senolytics: The Multiple Faces of Nrf2-Activating Phytochemicals in Cancer Adjuvant Therapy

    Full Text Available The reactivation of senescence in cancer and the subsequent clearance of senescent cells are suggested as therapeutic intervention in the eradication of cancer. Several natural compounds that activate Nrf2 (nuclear factor erythroid-derived 2-related factor 2 pathway, which is involved in complex cytoprotective responses, have been paradoxically shown to induce cell death or senescence in cancer. Promoting the cytoprotective Nrf2 pathway may be desirable for chemoprevention, but it might be detrimental in later stages and advanced cancers. However, senolytic activity shown by some Nrf2-activating compounds could be used to target senescent cancer cells (particularly in aged immune-depressed organisms that escape immunosurveillance. We herein describe in vitro and in vivo effects of fifteen Nrf2-interacting natural compounds (tocotrienols, curcumin, epigallocatechin gallate, quercetin, genistein, resveratrol, silybin, phenethyl isothiocyanate, sulforaphane, triptolide, allicin, berberine, piperlongumine, fisetin, and phloretin on cellular senescence and discuss their use in adjuvant cancer therapy. In light of available literature, it can be concluded that the meaning and the potential of adjuvant therapy with natural compounds in humans remain unclear, also taking into account the existence of few clinical trials mostly characterized by uncertain results. Further studies are needed to investigate the therapeutic potential of those compounds that display senolytic activity.

    Full Text Available Objective: To study the effect of adjuvant acupuncture therapy on serum cytokines and neurotransmitters in patients with post-stroke depression. Methods: Patients with poststroke depression who were treated in Traditional Chinese Medicine Hospital of Yuyang District Yulin City between May 2014 and February 2017 were selected as the research subjects and divided into two groups by random number table, control group of patients received neurotrophy, rehabilitation exercise, antidepressant drugs and other symptomatic treatment, and the acupuncture group received auxiliary acupuncture treatment on the basis of symptomatic treatment. The serum levels of nerve cytokines, inflammatory cytokines and neurotransmitters were detected before treatment as well as 2 weeks and 4 weeks after treatment. Results: 2 weeks and 4 weeks after treatment, serum BDNF, NGF, IGF-1, FGF-2, NE, DA and 5-HT levels of both groups of patients were higher than those before treatment while HCY, IL- 1β, IL-2, sIL-2R, TNF-α levels were lower than those before treatment, and serum BDNF, NGF, IGF-1, FGF-2, NE, DA and 5-HT levels of acupuncture group were higher than those of control group while HCY, IL-1β, IL-2, sIL-2R, TNF-α levels were lower than those of control group. Conclusion: Adjuvant acupuncture therapy for post-stroke depression can increase the secretion of nerve cytokines, reduce the secretion of inflammatory cytokines and regulate the function of monoamine neurotransmitters.

    Background: The use of adjuvant androgen deprivation therapy (ADT) combined with radiotherapy has become common in low-risk patients, although clinical trials have focused primarily on high-risk patients. This study examines the effectiveness of adjuvant ADT combined with radiotherapy for a wide range of patients treated in the 1990s. Methods and Materials: Prostate cancer survival was examined in a population based cohort of 31,643 patients aged 65 to 85 years who were diagnosed with nonmetastatic prostate cancer and treated with external beam radiotherapy and/or brachytherapy. Instrumental variable analysis methods were used to control for selection bias. Results: Patients with stage T3/T4 disease who received adjuvant ADT experienced improved 5-year and 8-year survival. No survival advantage was observed for men with T1/T2 disease during this interval. Conclusion: High-risk patients who receive primary radiotherapy have benefited from adjuvant ADT, whereas low-risk patients with disease confined to the prostate have not yet benefited from adjuvant therapy within the first 8 years after treatment. These findings are consistent with practice guidelines, which recommend adjuvant ADT for patients with high-risk disease

    2016-01-01

    Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients’ narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided. PMID:27517966

    Purpose: Despite the fact that retrospective reviews have documented pelvic failure rates ranging from 15-20% in patients with high-risk uterine-confined endometrial cancer who have received no or 'inadequate' RT, the role of RT has been questioned. We sought to analyze pelvic control and disease-free survival for a large data base of women with corpus cancers managed with initial surgery followed by adjuvant irradiation. Methods and Materials: Between 1983 and 1993, 294 patients received adjuvant postoperative RT from one of three academic radiation practices. RT consisted of vaginal brachytherapy alone in 28 patients, pelvic RT in 173 patients, pelvic RT with vaginal brachytherapy in 97 patients, and whole abdominal RT in 2 patients. Lymph nodes were evaluated in 49%. The median number of pelvic and periaortic LN in the pathology specimen were 6 and 4, respectively. Median follow up was 63 months. Results: 5-year disease-free survival (DFS) rate and pelvic control rates were 86 and 95%, respectively. Patient-related, treatment-related, and tumor-related characteristics were assessed for the effect on time to relapse. Unfavorable histology, older age, and capillary space invasion were univariately associated with decreased DFS and pelvic control. Pathologic Stage II patients had significantly worse DFS than Stage I patients. Multivariate analysis revealed that age, capillary space invasion, and histology were jointly predictive of disease free survival. Conclusion: The excellent pelvic control and disease-free survival of patients with uterine-confined disease in this series suggest that adjuvant RT should continue for patients with high risk disease. This analysis of a large group of postoperatively treated patients will provide a basis for determining alternative treatment strategies for patients who have an increased risk of disease recurrence despite RT

    In cardiac surgery poststernotomy mediastinitis continues to be a serious cause of morbidity and mortality. We report our experience with vacuum-assisted closure (VAC) therapy followed by reconstruction with M. pectoralis muscle flaps as treatment for deep sternal wound infections. Our group performed a retrospective analysis of 3630 consecutive cardiac surgical patients using median sternotomy from 11/2004 to 11/2007. After removing sternal wires, necrotic debris and potentially infective material, restabilisation of the sternum was performed and VAC therapy was employed. Wound closure and subsequent reconstruction were performed using a bilateral pectoralis muscle plasty. Of the analysed patients 16 female and 29 male patients suffered from deep sternal wound infections and were treated with VAC. The most common risk factors were diabetes mellitus odds ratio (OR 3.5), chronic obstructive pulmonary disease (COPD) (OR 2.9), use of bilateral mammarian artery (OR 2.0) and obesity (1.8). The median age of patients with deep sternal infections was similar to control patients. Staphylococcus epidermis was the most common pathogen (37.8%) followed by Enterococcus faecilis (22.2%) and Staphylococcus aureus (17.8). In 22.2% no pathogen could be detected. The 30 day mortality was 0%, the in-hospital mortality was 15.6%. The results of our studies demonstrate that vacuum therapy in conjunction with early and aggressive debridement is an effective strategy for treating poststernotomy mediastinitis. We consider pectoralis major muscle flap reconstruction as a safe technique and regard it as the primary choice for wound closure in poststernotomy mediastinitis.

    Cardiovascular complications induced by adjuvant cancer therapies may become symptomatic after many years, being responsible for increased morbidity and mortality in long-term survivors. We report a case of a 54-year old female admitted for severe heart failure induced by myocardial and valvular damage after postoperative adjuvant therapy for left breast cancer 6 years ago. Her recent history revealed nonST elevation myocardial infarction in the absence of significant cardiovascular risk factors. Transthoracic echocardiography, tissue Doppler imaging and speckle-tracking imaging revealed severe biventricular systolic dysfunction, severe mitral and tricuspid regurgitation and severe pulmonary hypertension.

All dogs had arthroscopic fragment removal and proximal ulnar osteotomy (PUO and were assigned into three groups (n=10/group: 1 control group with no further treatment beyond the PUO and fragment removal (SOC, 2 PUO + autologous ASCs and 3 PUO+ allogeneic ASCs. Each dog had force platform gait analysis, Canine Brief Pain Inventory (CBPI questionnaires, and delayed gadolinium enhanced magnetic resonance imaging scores prior to and six months after therapeutic intervention.Results: No serious adverse events were reported in any participant. 3/10 dogs in the control group, 3/10 autologous ASC group and 7/10 allogeneic ASC group participants were assessed as successful outcomes.Conclusion: This study provides preliminary safety data for the use of intra-articular allogeneic ASC therapy to treat osteoarthritis, and justification for larger clinical studies.Application: Clinical practitioners considering ASC therapy within their practice are provided with additional evidence of autologous ASC therapy for osteoarthritis. Researchers committed to developing and generating effective ASC therapies are provided with safety

    Muscle atrophy and strength decline are two of the most prominent characteristics in cancer patients undergoing cancer therapy, leading to decreased functional ability and reduced quality of life. Therefore, the aim is to systematically review research evidence of the effects of resistance exercise (RE) on lower-limb muscular strength, lean body mass (LBM), and body fat (BF) in cancer patients undertaking neoadjuvant or adjuvant therapy. This research was conducted using the following online database: Clinical Trial Register, Cochrane Trial Register, PubMed, SPORT Discus, and SciELO, from September 2014 until May 2015. We used the following keywords in various combinations with a systematic search: "Cancer therapy," "Wasting muscle," "Muscle loss," "Muscle function," "Neoadjuvant therapy," "Adjuvant thera-py," "Resistance Training," "Weight training," and "Exercise." After selection of 272 full-text articles, 14 publications were included in this meta-analysis. Resistance exercise (RE) during neoadjuvant or adjuvant therapy increased lower-limb muscular strength (mean: 26.22 kg, 95% CI [16.01, 36.43], heterogeneity: P = body mass (LBM) increased (mean 0.8 kg, 95% CI [0.7, 0.9], heterogeneity: P = 0.99, I 2  = 0%, P body fat (BF) (mean: -1.3 kg, 95% CI [-1.5, 1.1], heterogeneity: P = 0.93, I 2  = 0%, P cancer patients undergoing neoadjuvant and adjuvant therapy regardless of the kind of treatment. RE increases muscle strength, maintains LBM, and reduces BF in cancer patients undergoing adjuvant and neoadjuvant therapies. Cancer patients and survivors should consider undertaking RE as an effective countermeasure for treatment-related adverse effects to the musculoskeletal system.

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic

    Hyperparathyroidism in pregnancy is a threat to the health of both mother and fetus. The mothers suffer commonly from nephrolithiasis, hyperemesis, or even hypercalcemic crisis. Untreated disease will commonly complicate fetal development and fetal death is a significant risk. Treatment options, including medical and surgical therapy, are debated in the literature. This is a case series comprising seven patients with primary hyperparathyroidism in pregnancy. Data collected included symptoms at diagnosis, biochemical abnormalities, pathologic findings, treatment regimes, and subsequent maternal and fetal outcomes. Seven women, aged 20 to 39 years, presented with hyperparathyroidism during pregnancy. The earliest presented at 8 weeks and the latest at 38 weeks. Four of seven patients experienced renal calculi. Calcium levels were 2.7-3.5 mmol/l. All were found to have solitary parathyroid adenomas, of which two were in ectopic locations. Fetal complications included three preterm deliveries and one fetal death with no cases of neonatal tetany. Maternal and fetal complications could not be predicted based on duration or severity of hypercalcemia. Three patients were treated during pregnancy with surgery, and two of these had ectopic glands that required reoperations with a novel approach using Tc-99m sestamibi scanning during pregnancy to assist in localizing the abnormal gland. Four cases were treated postpartum with a combination of open and minimally invasive approaches after localization. No operative complications or fetal loss related to surgery were observed in this cohort. Primary hyperparathyroidism in pregnancy represents a significant risk for maternal and fetal complications that cannot be predicted by duration of symptoms or serum calcium levels. Surgical treatment should be considered early, and a minimally invasive approach with ultrasound is best suited to mitigating risk to mother and fetus. Equally important, Tc-99m sestamibi imaging may be used

    Full Text Available Aim: To evaluate the role of hyperbaric oxygen therapy (HBO2T with buccal mucosal tube urethroplasty in adult patients with hypospadias. Material and Method: Sixteen adult patients with hypospadias were included in our study. Patients with a short urethra and penile curvature were treated in two stages (orthoplasty buccal mucosal tube urethroplasty. Buccal mucosa was taken and prepared for tube urethroplasty around a 16 French (Fr nelaton catheter and the urethral tube was introduced between the urethral meatus and glans penis. Beginning the 1st postoperative day (HBO2T was applied for 10 sessions during weekdays in 13 patients. Results: The mean age was 21 (±1.23 years and mean follow-up time was 10.1 (±2.1 months. In the group who received HBO2T postoperatively (n=13, a two-stage (orthoplasty buccal mucosal tube urethroplasty procedure was performed in 6 (46%, and the mean length of graft was 5.4 (±1.23 cm. In this group of 13 the success rate without any additional manipulations (urethrotomy intern, fistula repair was 54% (7/13. After additional manipulations, complete healing was achieved in 11 out of 13 patients (84.6%. In the group who did not receive HBO2T postoperatively (n=3, a two-stage procedure was performed in 1 patient (33%, and the mean length of graft was 8 (±5 cm. In this group of 3, complete healing was not achieved in any of these patients as a result of the hypospadias surgery. However, after the additional manipulations, complete healing was achieved in 1 patient (33%. Discussion: Given the promising rates of surgical success, postoperative HBO2T might be considered as a supportive treatment modality for adult patients with hypospadias who undergo buccal mucosal tube urethroplasty. Randomized controlled studies are needed.

    Based on previous meta-analyses of randomized controlled trials (RCTs), the use of interferon alpha (IFN-alpha) in the adjuvant setting improves disease-free survival (DFS) in patients with high-risk cutaneous melanoma. However, RCTs have yielded conflicting data on the effect of IFN-alpha on overall survival (OS). We conducted a systematic review and meta-analysis to examine the effect of IFN-alpha on DFS and OS in patients with high-risk cutaneous melanoma. The systematic review was performed by searching MEDLINE, EMBASE, Cancerlit, Cochrane, ISI Web of Science, and ASCO databases. The meta-analysis was performed using time-to-event data from which hazard ratios (HRs) and 95% confidence intervals (CIs) of DFS and OS were estimated. Subgroup and meta-regression analyses to investigate the effect of dose and treatment duration were also performed. Statistical tests were two-sided. The meta-analysis included 14 RCTs, published between 1990 and 2008, and involved 8122 patients, of which 4362 patients were allocated to the IFN-alpha arm. IFN-alpha alone was compared with observation in 12 of the 14 trials, and 17 comparisons (IFN-alpha vs comparator) were generated in total. IFN-alpha treatment was associated with a statistically significant improvement in DFS in 10 of the 17 comparisons (HR for disease recurrence = 0.82, 95% CI = 0.77 to 0.87; P < .001) and improved OS in four of the 14 comparisons (HR for death = 0.89, 95% CI = 0.83 to 0.96; P = .002). No between-study heterogeneity in either DFS or OS was observed. No optimal IFN-alpha dose and/or treatment duration or a subset of patients more responsive to adjuvant therapy was identified using subgroup analysis and meta-regression. In patients with high-risk cutaneous melanoma, IFN-alpha adjuvant treatment showed statistically significant improvement in both DFS and OS.

    The discrepancy between the surgical technique and the type of adjuvant chemotherapy used in clinical trials and patient outcomes in terms of overall survival rates has led to the generation of different adjuvant treatment protocols in distinct parts of the world. The adjuvant treatment recommendation is generally chemoradiotherapy in the United States, perioperative chemotherapy in the United Kingdom and parts of Europe, and chemotherapy in Asia. These options mainly rely on the United States Intergroup-0116, United Kingdom British Medical Research Council Adjuvant Gastric Infusional Chemotherapy, and the Asian Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer and Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer trials. However, the benefits were evident for only certain patients, which were not very homogeneous regarding the type of surgery, chemotherapy regimens, and stage of disease. Whether the dissimilarities in survival are attributable to surgical technique or intrinsic biological differences is a subject of debate. Regardless of the extent of surgery, multimodal therapy may offer modest survival advantage at least for diseases with lymph node involvement. Moreover, in the era of individualized treatment for most of the other cancer types, identification of special subgroups comprising those who will derive more or no benefit from adjuvant therapy merits further investigation. The aim of this review is to reveal the historical evolution and future reflections of adjuvant treatment modalities for resected gastric cancer patients. PMID:27190583

  11. End points for adjuvant therapy trials: has the time come to accept disease-free survival as a surrogate end point for overall survival?

    Gill, Sharlene; Sargent, Daniel

    2006-06-01

    The intent of adjuvant therapy is to eradicate micro-metastatic residual disease following curative resection with the goal of preventing or delaying recurrence. The time-honored standard for demonstrating efficacy of new adjuvant therapies is an improvement in overall survival (OS). This typically requires phase III trials of large sample size with lengthy follow-up. With the intent of reducing the cost and time of completing such trials, there is considerable interest in developing alternative or surrogate end points. A surrogate end point may be employed as a substitute to directly assess the effects of an intervention on an already accepted clinical end point such as mortality. When used judiciously, surrogate end points can accelerate the evaluation of new therapies, resulting in the more timely dissemination of effective therapies to patients. The current review provides a perspective on the suitability and validity of disease-free survival (DFS) as an alternative end point for OS. Criteria for establishing surrogacy and the advantages and limitations associated with the use of DFS as a primary end point in adjuvant clinical trials and as the basis for approval of new adjuvant therapies are discussed.

    Fibromyalgia is a chronic pain syndrome associated with sleep disorders, fatigue and psychological symptoms. Combinations therapies, such as electrotherapy and therapeutic exercises have been used in the clinical practice. To assess the efficacy of high-frequency transcutaneous electrical nerve stimulation (TENS) as an adjuvant therapy to aerobic and stretching exercises, for the treatment of fibromyalgia. Controlled clinical trial. Unit of rehabilitation of a public hospital. Twenty-eight women aged 52.4±7.5 years, with fibromyalgia. A visual analogue scale measured pain intensity; tender points pain threshold, by dolorimetry; and quality of life, by the Fibromyalgia Impact Questionnaire. All subjects participated in an eight-week program consisting of aerobic exercises, followed by static stretching of muscle chains. In TENS group, high-frequency (150 Hz) was applied on bilateral tender points of trapezium and supraspinatus. TENS group had a greater pain reduction (mean change score=-2.0±2.9 cm) compared to Without TENS group (-0.7±3.7 cm). There was a difference between mean change scores of each group for pain threshold (right trapezium: 0.2±1 kg/cm² in TENS group and -0.2±1.2 kg/cm² in Without TENS group). In the evaluation of clinically important changes, patients receiving TENS had relevant improvement of pain, work performance, fatigue, stiffness, anxiety and depression compared to those not receiving TENS. It has suggested that high-frequency TENS as an adjuvant therapy is effective in relieving pain, anxiety, fatigue, stiffness, and in improving ability to work of patients with fibromyalgia. High-frequency TENS may be used as a short-term complementary treatment of fibromyalgia.

    In early breast cancer patients, the effects of hormonal therapy (tamoxifen and aromatase inhibitors) on plasma fibroblast growth factor 21 (FGF-21), lipid levels and body composition have not yet been investigated. Therefore, we aimed to analyze the relationship between FGF-21 and body composition as well as the effects of tamoxifen and aromatase inhibitors on plasma lipid levels, FGF-21, and body composition. A total of 72 patients were treated with either tamoxifen or aromatase inhibitors due to their menopausal status after adjuvant radiotherapy. Each patient was followed-up over a period of 1 year. Changes in body composition and serum lipid profile, glucose and FGF-21 levels were evaluated. We recorded the type of hormonal therapy, body mass index, waist-to-hip ratio, lipid profile, and FGF-21 levels both at the beginning and after 12 months. There was a statistically significant decrease in serum FGF-21 levels after 12 months of adjuvant endocrine therapy (46 ± 19.21 pg/ml vs. 30.99 ± 13.81 pg/ml, pbody water (pbody composition, glucose, lipid profile and FGF-21 were similar in tamoxifen and aromatase inhibitor groups. A positive correlation was found between basal weight, fat mass, fat-free mass and serum FGF-21 levels; however, the correlation was maintained only for the fat-free mass at the 12th month. As part of the present study, we suggest that both tamoxifen and aromatase inhibitors can reduce FGF-21 levels independently of body compositions, and these drugs can provide antihyperlipidemic, antidiabetic and cardio-protective effects. We also recommend that serum FGF-21 level can be utilized as a tumor biomarker in early-stage breast cancer and for monitoring purposes. FGF-21 levels may help physicians estimate prognosis, too. Further studies with larger populations may shed light on the role of FGF-21 in breast cancer.

    The purpose of this phase II study was to evaluate the efficacy and toxicity of fluorouracil and high-dose leucovorin (5-FU/LV) with pelvic irradiation as adjuvant therapy for patients with macroscopical resected rectal or recto-sigmoid cancer. Following surgery for stages II-III primary (52) or recurrent rectal cancer (4), 56 patients received 8 cycles of 5-FU/LV and pelvic irradiation. 5-FU doses were 200 mgr/m{sup 2} for cycles 2-3 and 300 mgr/m{sup 2} for cycles 1 and 4-8. LV doses remained fixed at 200 mgr/m{sup 2}. Pelvic radiation was started in the third week, between the first and second cycle. The total dose was 50.4 Gy. No serve complications had been recorded. The incidence of grade 3 diarrhea was 19%. Three patients presented leukopenia grade 3 (5%). In 44 patients (78%) the planned treatment could be administered. The median follow-up was 40 months (range 22-66). Seven patients had a local relapse (13%) and 6 developed distant metastasis (10%). The 3-year disease-free survival was 72% and the overall survival was 76%. These preliminary results show that combined post-operative 5-FU/LV and pelvic radiotherapy are well tolerated and present a reasonable local control and survival rates. This adjuvant treatment should be evaluated in randomized trials. (orig.).

    For more than three decades, postoperative chemotherapy-initially fluoropyrimidines and more recently combinations with oxaliplatin-has reduced the risk of tumor recurrence and improved survival for patients with resected colon cancer. Although universally recommended for patients with stage III disease, there is no consensus about the survival benefit of postoperative chemotherapy in stage II colon cancer. The most recent adjuvant clinical trials have not shown any value for adding targeted agents, namely bevacizumab and cetuximab, to standard chemotherapies in stage III disease, despite improved outcomes in the metastatic setting. However, biomarker analyses of multiple studies strongly support the feasibility of refining risk stratification in colon cancer by factoring in molecular characteristics with pathologic tumor staging. In stage II disease, for example, microsatellite instability supports observation after surgery. Furthermore, the value of BRAF or KRAS mutations as additional risk factors in stage III disease is greater when microsatellite status and tumor location are taken into account. Validated predictive markers of adjuvant chemotherapy benefit for stage II or III colon cancer are lacking, but intensive research is ongoing. Recent advances in understanding the biologic hallmarks and drivers of early-stage disease as well as the micrometastatic environment are expected to translate into therapeutic strategies tailored to select patients. This review focuses on the pathologic, molecular, and gene expression characterizations of early-stage colon cancer; new insights into prognostication; and emerging predictive biomarkers that could ultimately help define the optimal adjuvant treatments for patients in routine clinical practice. © 2015 by American Society of Clinical Oncology.

    2015-01-01

    Hepatocellular carcinoma (HCC), the second leading cause of cancer deaths worldwide, is difficult to treat and highly lethal. Since HCC is predominantly diagnosed in patients with cirrhosis, treatment planning must consider both the severity of liver disease and tumor burden. To minimize the impact to the patient while treating the tumor, techniques have been developed to target HCC. Anatomical targeting by surgical resection or locoregional therapies is generally reserved for patients with preserved liver function and minimal to moderate tumor burden. Patients with decompensated cirrhosis and small tumors are optimal candidates for liver transplantation, which offers the best chance of long-term survival. Yet, only 20%–30% of patients have disease amenable to anatomical targeting. For the majority of patients with advanced HCC, chemotherapy is used to target the tumor biology. Despite these treatment options, the five-year survival of patients in the United States with HCC is only 16%. In this review we provide a comprehensive overview of current approaches to target HCC. We also discuss emerging diagnostic and prognostic biomarkers, novel therapeutic targets identified by recent genomic profiling studies, and potential applications of immunotherapy in the treatment of HCC.

    Objective: To explore the role of adjuvant chemotherapy for patients with ypT0-2N0 rectal cancer treated by preoperative chemoradiation therapy (PCRT) and radical resection. Patients and Methods: A national consortium of 10 institutions was formed, and patients with ypT0-2N0 mid- and low-rectal cancer after PCRT and radical resection from 2004 to 2009 were included. Patients were categorized into 2 groups according to receipt of additional adjuvant chemotherapy: Adj CTx (+) versus Adj CTx (−). Propensity scores were calculated and used to perform matched and adjusted analyses comparing relapse-free survival (RFS) between treatment groups while controlling for potential confounding. Results: A total of 1016 patients, who met the selection criteria, were evaluated. Of these, 106 (10.4%) did not receive adjuvant chemotherapy. There was no overall improvement in 5-year RFS as a result of adjuvant chemotherapy [91.6% for Adj CTx (+) vs 87.5% for Adj CTx (−), P=.18]. There were no differences in 5-year local recurrence and distant metastasis rate between the 2 groups. In patients who show moderate, minimal, or no regression in tumor regression grade, however, possible association of adjuvant chemotherapy with RFS would be considered (hazard ratio 0.35; 95% confidence interval 0.14-0.88; P=.03). Cox regression analysis after propensity score matching failed to show that addition of adjuvant chemotherapy was associated with improved RFS (hazard ratio 0.81; 95% confidence interval 0.39-1.70; P=.58). Conclusions: Adjuvant chemotherapy seemed to not influence the RFS of patients with ypT0-2N0 rectal cancer after PCRT followed by radical resection. Thus, the addition of adjuvant chemotherapy needs to be weighed against its oncologic benefits.

    Purpose: To explore the mediating role of inflammatory parameters in the development of fatigue, pain, and potentially related depressive symptoms during radiation therapy for breast cancer and its mitigation by resistance exercise. Methods and Materials: Breast cancer patients scheduled for adjuvant radiation therapy were randomized to 12-week progressive resistance exercise training (EX) or a relaxation control group. Interleukin-6 (IL-6) and interleukin-1 receptor antagonist (IL-1ra) were measured in serum samples collected before, at the end, and 6 weeks after radiation therapy from 103 chemotherapy-naïve participants. Fatigue was assessed with the multidimensional Fatigue Assessment Questionnaire, pain with the European Organization for Research and Treatment of Cancer QLQ-C30, and depressive symptoms with the Center for Epidemiologic Studies Depression Scale. Analysis of covariance models, partial correlations, Freedman-Schatzkin tests, and R"2 effect-size measures for mediation were calculated. Results: The analysis of covariance models revealed a significant intervention effect on IL-6 (P=.010) and the IL-6/IL-1ra ratio (P=.018), characterized by a marked increase during radiation therapy among controls, but no significant change in EX. Interleukin-1 receptor antagonist did not change significantly in either group (P=.88). Increased IL-6 and IL-6/IL-1ra levels at the end of radiation therapy were significantly associated with increased physical fatigue and pain 6 weeks after radiation. We observed significant partial mediation by IL-6 and IL-6/IL-1ra of the effect of resistance exercise on physical fatigue (Freedman-Schatzkin P=.023 and P<.001) and pain (both P<.001). Hereby IL-6 and IL-6/IL-1ra mediated between 15% and 24% of the variance of physical fatigue and pain explained by the intervention. Conclusions: This randomized, controlled trial showed a significantly increased proinflammatory cytokine level after adjuvant radiation therapy in breast

    Between 1969 and 1980, 242 cases of stage IB cancer of the cervix were referred to the department of radiation oncology for curative radiation therapy. In 186 cases treatment was with radiation therapy alone. In 56 cases treatment included adjuvant postoperative radiation therapy; a minimum follow-up of 5 years has been carried out in this group. In 17 cases radiation therapy followed a simple hysterectomy for an unexpected stage IB cancer of the cervix. In 39 cases radiation therapy was given after a radical hysterectomy for stage IB cancer of the cervix because of positive margins and/or positive pelvic lymph nodes

    A 53-year-old male. We performed endoscopic mucosal resection (EMR) for squamous cell carcinoma of the esophagus in June, 2000 [SM1, ly (+), v (+)]. We performed chemoradiotherapy as adjuvant treatment. We diagnosed metachronous esophageal cancer six years later and performed EMR. Pathologically it was diagnosed as squamous cell carcinoma T1a-MM, ly0, v0. A 61-year-old male. We performed EMR for squamous cell carcinoma of the esophagus in November, 2000 [SM1, ly (-), v (+)]. We performed chemoradiotherapy as adjuvant treatment. We diagnosed metachronous esophageal cancer five years later, and performed EMR. Pathologically it was diagnosed as squamous cell carcinoma T1a-MM, ly1, v0. The two cases were diagnosed by six monthly endoscopic examination. The carcinoma were small, equal to less than 10 mm, but it was that their growth rate was fast, and it was noted that they were collapsed lesions whose circumference had swelled. In addition, both of the lesions had an invasion depth of T1a-MM. (author)

    Both native IFNα2b and pegylated IFNα2b (PegIFNα2b) are approved for the adjuvant treatment of high-risk melanoma. This review compares the toxicity profiles of high-dose IFNα2b (HDI) and PegIFNα2b, and provides recommendations on the management of common PegIFNα2b-related toxicities, based on available clinical data and published literature. The toxicity profile of PegIFNα2b at the approved dose (6 μg/kg/week for 8 weeks then 3 μg/kg/week for up to 5 years) is qualitatively similar to HDI in melanoma. The most common adverse events (AEs) are fatigue, anorexia, hepatotoxicity, flu-like symptoms, injection site reactions and depression. However, fatigue and flu-like symptoms appear less severe with PegIFNα2b, and toxicity seems to occur earlier, whereas with HDI toxicity may increase with time. Most AEs can be managed effectively by dose modification and aggressive symptom control. Dosing to tolerance using a three-step dose reduction schedule to maintain an ECOG performance status of 0 - 1 may enable patients experiencing toxicity to remain on treatment; this can be applied readily in clinical practice. PegIFNα2b is therefore a valuable alternative option for adjuvant treatment in melanoma, with a toxicity profile similar to that of HDI overall but a more convenient administration schedule.

    2017-05-01

    In the last few years, new adjuvant endocrine treatment options have become available in young women with early breast cancer, such as the addition of ovarian function suppression to tamoxifen or aromatase inhibitors. Treatment duration has been also adapted in the latest guidelines based on the individual risk of recurrence. The oncologist is therefore challenged to precisely assess the risk of recurrence according to currently available predictive and prognostic factors in order to offer the most appropriate therapeutic option to the individual patient, considering also potential side effects, quality of life, pregnancy planning and patients' preferences. The adjuvant treatment planning should always be discussed and agreed in a multidisciplinary context. Tamoxifen remains the standard of care in low-risk patients or in case of intolerance to combined treatment with pharmacological ovarian function suppression or aromatase inhibitors. Combination treatment is indicated in intermediate high-risk disease. The patient should always be considered an active partner in the treatment decision process, to improve treatment motivation and adherence. Finally, the therapeutic choice should take into account drug availability and pharmacoeconomic issues, which unfortunately may prevent, in many low-income countries, the provision of such effective treatments.

    The addition of 5-fluorouracil (5-FU) or its prodrug capecitabine to radiotherapy (RT) is a standard approach in the neo-adjuvant treatment of patients with rectal tumors extending beyond the muscularis propria (stage II) and/or with clinical evidence of regional lymph node metastases (stage III). According to European randomized trials, the combined treatment modality resulted in favorable local control rates as compared with radiotherapy (RT) alone, but no improvement was found regarding the occurrence of distant metastases or overall survival. In an effort to further enhance the response rates and to decrease the high incidence of distant metastases in locally advanced rectal cancer patients, the addition of other chemotherapeutical drugs and biologic agents as radiation sensitizers to neo-adjuvant 5-FU based chemoradiotherapy (CRT) has been recently investigated. The role of those agents is however questionable as first results from phase III data do not show improvement on pathologic complete remission and circumferential resection margin negative resection rates as compared to 5-FU based CRT, nevertheless an increased toxicity.

    Full Text Available Objective: To study the effect of adjuvant low-molecular-weight heparin therapy on placental hypoxia and cell apoptosis in puerperae with severe preeclampsia. Methods: A total of 94 puerperae with severe preeclampsia who received treatment and safely gave birth in our hospital between May 2014 and May 2016 were selected as the research subjects and randomly divided into the LMWH group who received low-molecular-weight heparin combined with conventional symptomatic treatment and the control group who received conventional symptomatic treatment. Before and after treatment, serum was collected respectively to determine the levels of placental hypoxia-related cytokines, and after delivery, the placentas were collected to detect oxidative stress indexes and cell apoptosis indexes. Results: After treatment, serum PLGF and PAPP-A levels of both groups were significantly higher than those before treatment while sFlt-1 and sEng levels were significantly lower than those before treatment, and after treatment, serum PLGF and PAPP-A levels of LMWH group were significantly higher than those of control group while sFlt-1 and sEng levels were significantly lower than those of control group; ROS and RNS levels as well as Fas, FasL, caspase-3 and caspase-8 protein expression in placenta tissue of LMWH group were significantly lower than those of control group while GPx-1, SOD-1 and Trx levels as well as Survivin, XIAP and Bcl-2 protein expression were significantly higher than those of control group. Conclusion: Adjuvant low-molecular-weight heparin therapy can relieve the placental hypoxia, improve oxidative stress reaction and inhibit cell apoptosis in puerperae with severe preeclampsia.

    Purpose: To develop multi-institutional consensus clinical target volumes (CTVs) and organs at risk (OARs) for male and female bladder cancer patients undergoing adjuvant radiation therapy (RT) in clinical trials. Methods and Materials: We convened a multidisciplinary group of bladder cancer specialists from 15 centers and 5 countries. Six radiation oncologists and 7 urologists participated in the development of the initial contours. The group proposed initial language for the CTVs and OARs, and each radiation oncologist contoured them on computed tomography scans of a male and female cystectomy patient with input from ≥1 urologist. On the basis of the initial contouring, the group updated its CTV and OAR descriptions. The cystectomy bed, the area of greatest controversy, was contoured by another 6 radiation oncologists, and the cystectomy bed contouring language was again updated. To determine whether the revised language produced consistent contours, CTVs and OARs were redrawn by 6 additional radiation oncologists. We evaluated their contours for level of agreement using the Landis-Koch interpretation of the κ statistic. Results: The group proposed that patients at elevated risk for local-regional failure with negative margins should be treated to the pelvic nodes alone (internal/external iliac, distal common iliac, obturator, and presacral), whereas patients with positive margins should be treated to the pelvic nodes and cystectomy bed. Proposed OARs included the rectum, bowel space, bone marrow, and urinary diversion. Consensus language describing the CTVs and OARs was developed and externally validated. The revised instructions were found to produce consistent contours. Conclusions: Consensus descriptions of CTVs and OARs were successfully developed and can be used in clinical trials of adjuvant radiation therapy for bladder cancer.

    Despite introduction of effective chemotherapy protocols, it has remained uncertain, if patients with colorectal cancer (CRC) liver metastases should receive adjuvant therapy. Clinical or molecular predictors may help to select patients at high risk for disease recurrence and death who obtain a survival advantage by adjuvant chemotherapy. A total of 297 patients with potentially curative resection of CRC liver metastases were analyzed. These patients had no neoadjuvant therapy, no extrahepatic disease and negative resection margins. The primary endpoint was overall survival. Patients' risk status was evaluated using the Memorial Sloan-Kettering Cancer Center clinical risk score (MSKCC-CRS). Multivariable analyses were performed using Cox proportional hazard models. A total of 137 (43%) patients had a MSKCC-CRS > 2. Adjuvant chemotherapy was administered to 116 (37%) patients. Patients who received adjuvant chemotherapy were of younger age (p = 0.03) with no significant difference in the presence of multiple metastases (p = 0.72) or bilobar metastases (p = 0.08). On multivariate analysis adjuvant chemotherapy was associated with improved survival in the entire cohort (Hazard ratio 0.69; 95% confidence interval 0.69-0.98). It improved survival markedly in high-risk patients with a MSKCC-CRS > 2 (HR 0.40; 95% CI 0.23-0.69), whereas it was of no benefit in patients with a MSKCC-CRS ≤ 2 (HR 0.90; 95% CI 0.57-1.43). The MSKCC-CRS offers a tool to select patients for adjuvant therapy after resection of CRC liver metastases. Validation in independent patient cohorts is required.

    Full Text Available Several drugs and their associations are being used for adjuvant or complementary chemotherapy with the aim of improving results of gastric cancer treatment. The objective of this study was to verify the impact of these drugs on nutrition and on survival rate after radical treatment of 53 patients with gastric cancer in stage III of the TNM classification. A control group including 28 patients who had only undergone radical resection was compared to a group of 25 patients who underwent the same operative technique followed by adjuvant polychemotherapy with FAM (5-fluorouracil, Adriamycin, and mitomycin C. In this latter group, chemotherapy toxicity in relation to hepatic, renal, cardiologic, neurological, hematologic, gastrointestinal, and dermatological functions was also studied. There was no significant difference on admission between both groups in relation to gender, race, macroscopic tumoral type of tumor according to the Borrmann classification, location of the tumor in the stomach, length of the gastric resection, or response to cutaneous tests on delayed sensitivity. Chemotherapy was started on average, 2.3 months following surgical treatment. Clinical and laboratory follow-up of all patients continued for 5 years. The following conclusions were reached: 1 The nutritional status and incidence of gastrointestinal manifestation were similar in both groups; 2 There was no occurrence of cardiac, renal, neurological, or hepatic toxicity or death due to the chemotherapeutic method per se; 3 Dermatological alterations and hematological toxicity occurred exclusively in patients who underwent polychemotherapy; 4 There was no significant difference between the rate and site of tumoral recurrence, the disease-free interval, or the survival rate of both study groups; 5 Therefore, we concluded, after a 5-year follow-up, chemotherapy with the FAM regimen did not increase the survival rate.

    The aim of this study was to investigate possible differences in cellular immunity between chemo- and/or radiotherapy groups during a long interval after surgery in esophageal squamous cell carcinoma (ESCC) patients. Cellular immunity was assessed as peripheral lymphocyte subsets in response to chemotherapy (CT), radiotherapy (RT) and CT+RT by flow cytometric analysis. There were 139 blood samples obtained at different time points relative to surgery from 73 patients with ESCC. The changes in the absolute and relative proportions of lymphocyte phenotypes were significant among the adjuvant therapy groups. There were significant differences in the absolute counts of CD4+ and CD8+ T cells among the interval groups, and a lower CD4/CD8 ratio was found in patients following a prolonged interval. RT alone had a profound effect on the absolute counts of CD3+, CD4+ and CD8+ T cells compared with the other groups. CD4+ T cells exhibited a decreasing trend during a long interval, leading to a prolonged T-cell imbalance after surgery. Univariate analysis revealed that the interaction of the type of adjuvant therapy and the interval after surgery was correlated only with the percentage of CD4+ T cells. The percentage of CD4+ T cells can be used as an indicator of the cellular immunity after surgery in ESCC patients. However, natural killer cells consistently remained suppressed in ESCC patients following adjuvant therapy after surgery. These findings confirm an interaction between adjuvant therapy and the interval after surgery on peripheral CD4+ T cells, and implies that adjuvant therapy may have selective influence on the cellular immunity of ESCC patients after surgery.

    Primary radiotherapy as a means of managing stage I and II breast cancer is receiving increasing attention. In a prospectively randomized trial comparing modified radical mastectomy to lumpectomy followed by definitive radiotherapy, we evaluated whether radiotherapy has a deleterious effect on the ability to administer adjuvant doxorubicin and cyclophosphamide to patients with histologically positive axillary lymph nodes. All patients were treated with an identical regimen, and doses were escalated to the same degree until myelosuppression occurred. There were no significant differences in the amount of chemotherapy administered to either treatment group. Patients in both groups received approximately 100% of the predicted dose of doxorubicin and approximately 117% of the predicted dose of cyclophosphamide. At present, we have no evidence that there are differences in recurrence rates as a function of the quantity of drug received, although longer follow-up is required

    Pancreatic surgery encompasses complex operations with significant potential morbidity. Greater experience in minimally invasive surgery (MIS) has allowed resections to be performed laparoscopically and robotically. This study evaluates the impact of surgical approach in resected pancreatic cancer. The National Cancer Data Base (2010-2012) was reviewed for patients with stages 1-3 resected pancreatic carcinoma. Open approaches were compared to MIS. A sub-analysis was then performed comparing robotic and laparoscopic approaches. Of the 9047 patients evaluated, surgical approach was open in 7511 (83%), laparoscopic in 992 (11%), and robotic in 131 (1%). The laparoscopic and robotic conversion rate to open was 28% (n = 387) and 17% (n = 26), respectively. Compared to open, MIS was associated with more distal resections (13.5, 24.3%, respectively, p offered significantly shorter LOS in all types. Multivariate analysis demonstrated no survival benefit for any MIS approach relative to open (all, p > 0.05). When adjusted for patient, disease, and treatment characteristics, TTC was not an independent prognostic factor (HR 1.09, p = 0.084). MIS appears to offer comparable surgical oncologic benefit with improved LOS and shorter TTC. This effect, however, was not associated with improved survival.

    In Taiwan, oral cancer has becomes the fastest growth male cancer disease due to the betel nut chewing habit combing with smoking and alcohol-drinking lifestyle of people. In order to eliminate the systemic phototoxic effect of 5-aminolevulinic acid (ALA), this study was designed to use a topical ALA-mediated PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 10 to 12 weeks. Cancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical ALA-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when ALA reached its peak level in the lesional epithelial cells after topical application of ALA gel. We found that ALA reached its peak level in precancerous lesions about 2.5 hrs after topical application of ALA gel. The cancerous lesions in hamsters were then treated with topical ALA -mediated PDT with light exposure dose of 150 J/cm2 using LED 635 nm fiber-guided light device. Visual examination demonstrated that adjuvant topical ALA -mediated PDT group has shown better therapeutic results in compared to those of non-adjuvant topical ALA-mediated PDT group for DMBA-induced hamster buccal pouch precancerous lesions.

    The study included 128 patients with stage T2-4N0-3M0 locally advanced breast cancer. All patients were divided into two groups. Group I (study group) consisted of 68 patients, who received neutron therapy, and group II (control group) comprised 60 patients, who received electron beam therapy. Neutron therapy was well tolerated by the patients and 1-2 grade radiation skin reactions were the most common. Neutron therapy was shown to be effective in multimodality treatment of the patients with locally advanced breast cancer. The 8-year recurrence-free survival rate in the patients with locally advanced breast cancer was 94.5 ± 4.1% after neutron therapy and 81.4 ± 5.9% after electron beam therapy (p = 0.05).

    Controversy persists as regards the indications and results of surgery in the treatment of patients with stage pIIIA-N2 non-small cell lung cancer (NSCLC). The objective of this study was to analyze the overall survival of a multicentre series of these patients and the role of adjuvant treatment, looking for factors that may define subgroups of patients with an increased benefit from this treatment. A retrospective study was conducted on 287 patients, with stage pIIIA-N2 NSCLC subjected to complete resection, taken from a multi-institutional database of 2.994 prospectively collected consecutive patients who underwent surgery for lung cancer. Adjuvant treatment was administered in 238 cases (82.9%). Analyses were made of the age, gender, histological type, administration of induction and adjuvant chemotherapy and/or radiation therapy treatments. The 5-year survival was 24%, with a median survival of 22 months. Survival was 26.5% among patients receiving with adjuvant treatment, versus 10.7% for those without it (P=.069). Age modified the effect of adjuvant treatment on survival (interaction P=.049). In patients under 70 years of age with squamous cell carcinoma, adjuvant treatment reduced the mortality rate by 37% (hazard ratio: 0,63; 95% CI; 0,42-0,95; P=.036). Completely resected patients with stage pIIIA-N2 NSCLC receiving adjuvant treatment reached higher survival rates than those who did not. Maximum benefit was achieved by the subgroup of patients under 70 years of age with squamous cell carcinoma. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    Full Text Available Objective: To study the clinical results and prognostic factors of patients with glioblastoma multiforme (GBM treated by postoperative radiation therapy (PORT and concomitant temozolomide followed by adjuvant temozolomide. Methods: From 2005 to 2008, 215 patients (median age 48 years with GBM were treated with PORT plus temozolomide chemotherapy. Radiation therapy (RT was employed with a dose of 60 Gy in 30 fractions over 6 weeks by conventional fractionation with concomitant temozolomide (75 mg/m 2 /day. Adjuvant therapy consisted of 6 cycles of temozolomide (150 mg/m 2 for 5 days, 28 days cycle. The primary end point of the study was overall survival (OS, and the secondary end points were progression free survival (PFS and toxicity. OS was determined with respect to different variables to study the prognostic significance. Results: Median follow up was 11 months (range 2-50 months. Median OS and PFS were 13 months and 11 months respectively. The 1-year and 2-year OS was 44% and 18% respectively. There was no statistical significant impact of age, sex, KP score, anatomical location and extent of surgery. Presentation without seizures (on univariate analysis and 6 cycles of adjuvant temozolomide therapy (on univariate as well as multivariate analysis were found significant prognostic factors. Sixteen patients developed grade III-IV neutropenia/thrombocytopenia during the course of RT. Conclusion: Our results authenticate the role of concomitant and adjuvant temozolomide chemotherapy in combination with PORT for the management of GBM patients. We strongly recommend complete 6 cycle of adjuvant temozolomide since it significantly improved the survival in our study.

    To evaluate the characteristics and overall survival rates of early stage cervical cancer (FIGO IB-IIA) patients who receive definitive radiation therapy and those who are prescribed adjuvant postoperative radiation and to conduct a factors analysis of the variables that affect the overall survival rates in both groups of therapy. The medical records of 85 patients with cervical cancer FIGO stages IB-IIA who were treated at the Department of Radiotherapy of Cipto Mangunkusumo Hospital were reviewed and analyzed to determine their overall survival and the factors that affected it between a definitive radiation group and an adjuvant postoperative radiation group. There were 25 patients in the definitive radiation and 60 patients in the adjuvant radiation group. The overall survival rates in the adjuvant radiation group at years one, two, and three were 96.7%, 95%, and 93.3%, respectively. Negative lymph node metastasis had an average association with overall survival (p 12 g/dl was a factor with an average association with the overall survival (p cervical cancer FIGO stage IB-IIA patients who received definitive radiation or adjuvant postoperative radiation. Negative lymph node metastasis had an effect on the overall survival rate in the adjuvant postoperative radiation group, while a preradiation Hb level >12 g/dl tended to affect the overall survival in the definitive radiation group patients.

    To evaluate the efficacy of L-ornithine-L-aspartate (LOLA) as an adjuvant therapy in cirrhotic patients with hepatic encephalopathy (HE). Study Design: Randomized placebo controlled study. Place and Duration of Study: The Aga Khan University Hospital, Karachi in the year 2003-2004. Methodology: Patients with HE were randomized to receive LOLA or placebo medicine as an adjuvant to treatment of HE. Number connection test-A (NCT-A), ammonia level, clinical grade of HE and duration of hospitalization were assessed. Results: Out of 120 patients, there were 62 males with mean age of 57 +- 11 years. Improvement in HE was higher (n=40, 66.7%) in LOLA group as compared to the placebo group (n=28, 46.7%, p=0.027). In patients with grade I or less encephalopathy, improvement was seen in 6 (35.3%) and 3 (20%) patients in LOLA and placebo groups respectively (p=0.667). Patients with HE grade II and above showed improvement in 34 (79.1%) and 25 (55.6%) cases in LOLA and placebo group respectively (p=0.019). On multivariate analysis patients with HE of grade II and above showed prothrombin time, creatinine level and use of LOLA influencing the outcome. Duration of hospitalization was 93.6 +- 25.7 hours and 135.2 +- 103.5 hours in LOLA and placebo groups respectively (p=0.025). No side effects were observed in either groups. Conclusion: In cirrhotic patients with advanced hepatic encephalopathy treatment with LOLA was safe and associated with relatively rapid improvement and shorter hospital stay. (author)

    Full Text Available Latent HIV reservoirs in infected individuals prevent current treatment from eradicating infection. Treatment strategies against latency involve adjuvants for viral reactivation which exposes viral particles to antiretroviral drugs. In this study, the effect of novel triterpenoids isolated from Ocimum labiatum on HIV-1 expression was measured through HIV-1 p24 antigen capture in the U1 latency model of HIV-1 infection and in peripheral blood mononuclear cells (PBMCs of infected patients on combination antiretroviral therapy (cART. The mechanism of viral reactivation was determined through the compound’s effect on cytokine production, histone deacetylase (HDAC inhibition, and protein kinase C (PKC activation. Cytotoxicity of the triterpenoids was determined using a tetrazolium dye and flow cytometry. The isolated triterpene isomers, 3-hydroxy-4,6a,6b,11,12,14b-hexamethyl-1,2,3,4,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-octadecahydropicene-4,8a-dicarboxylic acid (HHODC, significantly (p < 0.05 induced HIV-1 expression in a dose-dependent manner in U1 cells at non-cytotoxic concentrations. HHODC also induced viral expression in PBMCs of HIV-1 infected patients on cART. In addition, the compound up-regulated the production of interleukin (IL-2, IL-6, tumour necrosis factor (TNF-α, and interferon (IFN-γ but had no effect on HDAC and PKC activity, suggesting cytokine upregulation as being involved in latency activation. The observed in vitro reactivation of HIV-1 introduces the adjuvant potential of HHODC for the first time here.

    Skeletal metastasis of breast carcinoma is refractory to intensive chemo-radiation therapy and therefore is assumed impossible to cure. Here, we report an advanced case of breast cancer with vertebra-Th7 metastasis that showed complete response to combined treatments with formalin-fixed autologous tumor vaccine (AFTV), palliative radiation therapy with 36 Gy, and adjuvant chemotherapy with standardized CEF (cyclophosphamide, epirubicin, and 5FU), zoledronic acid, and aromatase inhibitors following mastectomy for the breast tumor. The patient has been disease-free for more than 4 years after the mammary surgery and remains well with no evidence of metastasis or local recurrence. Thus, a combination of AFTV, palliative radiation therapy, and adjuvant chemotherapy may be an effective treatment for this devastating disease.

    Trials of adjuvant radiation after cystectomy are under development. There are no studies comparing radiation techniques to inform trial design. This study assesses the effect on bowel and rectal dose of 3 different modalities treating 2 proposed alternative clinical target volumes (CTVs). Contours of the bowel, rectum, CTV-pelvic sidewall (common/internal/external iliac and obturator nodes), and CTV-comprehensive (CTV-pelvic sidewall plus cystectomy bed and presacral regions) were drawn on simulation images of 7 post-cystectomy patients. We optimized 3-dimensional conformal radiation (3-D), intensity-modulated radiation (IMRT), and single-field uniform dose (SFUD) scanning proton plans for each CTV. Mixed models regression was used to compare plans for bowel and rectal volumes exposed to 35% (V{sub 35%}), 65% (V{sub 65%}), and 95% (V{sub 95%}) of the prescribed dose. For any given treatment modality, treating the larger CTV-comprehensive volume compared with treating only the CTV-pelvic sidewall nodes significantly increased rectal dose (V{sub 35%} {sub rectum}, V{sub 65%} {sub rectum}, and V{sub 95%} {sub rectum}; p < 0.001 for all comparisons), but it did not produce significant differences in bowel dose (V{sub 95%} {sub bowel}, V{sub 65%} {sub bowel}, or V{sub 35%} {sub bowel}). The 3-D plans, compared with both the IMRT and the SFUD plans, had a significantly greater V{sub 65%} {sub bowel} and V{sub 95%} {sub bowel} for each proposed CTV (p < 0.001 for all comparisons). The effect of treatment modality on rectal dosimetry differed by CTV, but it generally favored the IMRT and the SFUD plans over the 3-D plans. Comparison of the IMRT plan vs the SFUD plan yielded mixed results with no consistent advantage for the SFUD plan over the IMRT plan. Targeting a CTV that spares the cystectomy bed and presacral region may marginally improve rectal toxicity but would not be expected to improve the bowel toxicity associated with any given modality of adjuvant radiation

    Purpose: The aim of our study was to evaluate patterns and predictors of early biochemical recurrence (eBCR) after radical prostatectomy (RP) and adjuvant radiation therapy (aRT) in order to identify which individuals might benefit from additional treatments. Methods and Materials: We evaluated 390 patients with pT 3 N 0 prostate cancer (PCa) receiving RP and aRT at 6 European centers between 1993 and 2006. Patients who were free from BCR at 0.2 ng/mL within 2 or 3 years after aRT. Uni- and multivariable Cox regression analyses predicting overall and eBCR after aRT were fitted. Covariates consisted of preoperative PSA results, surgical margins, pathological stage, Gleason score, and aRT dose. Results: Overall, 5- and 8-year BCR-free survival rates were 77.1% and 70.8%, respectively. At a median follow-up of 86 months after aRT, 33 (8.8%) and 55 (14.6%) men experienced BCR within 2 or 3 years after aRT, respectively. In multivariable analyses, Gleason scores of 8 to 10 represented the only independent predictor of eBCR after aRT (all, P≤.01). The risk of BCR was significantly higher in patients with a Gleason score of 8 to 10 disease than in those with Gleason 2 to 6 within 24 months after treatment, after adjusting for all covariates (all, P≤.04). However, given a 24-month BCR free period, the risk of subsequent BCR for men with poorly differentiated disease was equal to that of men with less aggressive disease (all, P≥.3). Conclusions: High Gleason score represents the only predictor of eBCR after RP and aRT in patients affected by pT 3 N 0 PCa. Given the association between early PSA recurrence, clinical progression, and mortality, these patients might be considered candidates for adjuvant medical therapy and/or prophylactic whole-pelvis radiation therapy in addition to aRT, delivered to the prostatic bed

    Churg-Strauss syndrome (CSS) is an anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis; it is extremely rare in childhood and defined according to the Chapel-Hill Consensus as an eosinophil-rich and granulomatous inflammation involving the respiratory tract and necrotizing vasculitis affecting small to medium-sized vessels. Children commonly have a history of asthma and sinusitis whilst clinical presentation typically involves pulmonary tract and less frequently skin, heart, gastrointestinal tract, and peripheral nerves. Cardiopulmonary disease is higher in children and prognosis is worse. It is associated with significant eosinophilia and raised serum IgE-levels. ANCA are only found in 25% of childhood cases. Here we report the case of a 10-year-old girl who presented to us with vomiting, abdominal pain, and weight loss, paresthesias of lower extremities and breathlessness as well as a history of asthma, sinusitis and allergic rhinitis. She was treated with corticosteroids, cyclophosphamide, intravenous immunoglobulin, mycophenolate mofetil (MMF), and rituximab. However, remission was only achieved after initiation of omalizumab therapy, a recombinant humanized anti-IgE antibody. To the best of our knowledge this is the first pediatric patient suffering from CSS successfully managed with adjuvant anti-IgE therapy resulting in the control of respiratory as well as gastrointestinal symptoms. © 2013 Wiley Periodicals, Inc.

    Full Text Available For the first time, we discovered a small proportion of aqueous fraction from Saw Palmetto apart from the fatty acid-rich fraction exhibited pharmacological activity. Therefore, this study aims to explore the anti-tumor potential of red pigmented aqueous fraction of Saw Palmetto, NYG on human hepatocellular carcinoma and its possible targets. Subcutaneous xenograft and orthotopic implantation models of HCC were used to evaluate the tumor inhibitory effect of NYG. Human hepatocellular carcinoma (HCC cell lines and human umbilical vein endothelial cells (HUVEC were used as in vitro model. The mRNA expression was conducted by qPCR. Protein expression was monitored by immunoblotting and immunohistochemistry. Cell migration and blood vessel formation were determined by chamber assay and tube formation assay, respectively. Significant tumor inhibition of NYG in dose-dependent manner was observed on subcutaneous xenograft and orthotopic HCC model. NYG has no direct action on cell viability or VEGF secretion of HCC cells. However, NYG reduced in vitro migration and vessel formation activities of HUVEC cells, as well as in vivo intratumoral neovascularization. NYG attenuated extracellular signal-regulated kinases (ERK activation in endothelial cells, which may be associated with the suppression of migration and tube formation of HUVEC. NYG suppressed tumor expansion of HCC via inhibiting neovascularization, and may be potential adjuvant treatment for HCC.

    One of the complications of long-term treatment of Parkinson's disease (PD) with levodopa is the development of motor complications. Generally, when motor complications develop, clinicians add in an additional drug (to the levodopa regimen) from one of three other classes of anti-Parkinsonian treatments (dopamine agonists, catechol-O-methyl transferase inhibitors (COMTIs) or monoamine oxidase type B inhibitors (MAOBIs)). However, despite trials having shown that these drugs are beneficial compared to placebo, it remains unclear as to the best way to treat patients experiencing motor complications and whether one class of drug is more effective than another. This meta-analysis aims to assess more reliably the benefits and risks of the three classes of drugs (dopamine agonists, COMTIs and MAOBIs) currently used as adjuvant treatment to levodopa in PD patients suffering from motor complications. The three drug classes were compared with the aim of determining whether one class of drug provides better symptomatic control than another. We searched CENTRAL (The Cochrane Library), MEDLINE, EMBASE, PubMed, LILACS and Web of Science, plus major journals in the field, abstract books, conference proceedings and reference lists of retrieved publications. Randomised trials comparing an orally administered dopamine agonist, COMTI or MAOBI versus placebo, both on a background of levodopa therapy, in PD patients experiencing motor complications. Two authors independently extracted data on off-time, levodopa dose, motor complications, side-effects, treatment concordance, clinician-rated disability, mortality, quality of life and health economic data. Forty-four eligible trials, involving 8436 participants were identified. Compared to placebo, adjuvant therapy significantly reduced off-time (-1.05 hours/day, 95% confidence interval (CI) -1.19 to -0.90; P<0.00001), the required levodopa dose (-55.65 mg/day, CI -62.67 to -48.62; P<0.00001) and improved UPDRS scores (UPDRS ADL score

    Purpose: The aim of this study is to investigate efficacy and toxicity of 1 year of capecitabine metronomic therapy preceded by standard adjuvant chemotherapy in triple-negative breast cancer (TNBC) patients. Methods: Between June 2010 and February 2012, 19 women with pathologically proven operable TNBC, who had received standard adjuvant chemotherapy before were enrolled. Patients received 1 year of oral capecitabine metronomic therapy (650 mg/m2, twice every day), after standard adjuvant chemotherapy and radiotherapy if indicated. The primary endpoints of this study were disease-free survival rates (DFS) and safety profile. Secondary end point was overall survival (OS). Results: The maximal follow-up was 46.6 months with a median of 30.1 months ±11.525 (95% CI; 28.5-33.5 months). The median DFS was 41.7 months ±2.7 (95% CI; 36.5-46.9). No one developed locoregional recurrence. The actuarial rate of DFS was 88.8% and 82.05% at 2 and 3 years, respectively. At the time of the analyses, no patients had died and the median OS was not reached. Treatment-related adverse events were manageable with only 1 patient (5.3%) suffering from Grade 3/4 hand-foot syndrome and another 1 patient (5.3%) suffering from Grade 3 diarrhea. No Grade 3/4 hematologic toxicity was recorded. All patients received full doses of capecitabine throughout the study and dose reduction was not required in any of our patients. Conclusion: One year of capecitabine metronomic therapy preceded by standard adjuvant chemotherapy, is active and well-tolerated in TNBC patients previously treated with standard adjuvant chemotherapy.

    Purpose: During adjuvant radiotherapy (RT) for rectal cancer, patients receiving 5-fluorouracil (5-FU) by protracted venous infusion have a higher risk of diarrhea than have patients receiving bolus 5-FU. Toxicity from a previously reported randomized clinical trial was analyzed to quantify the difference in this risk. Additionally, the persistence of diarrhea after RT was analyzed. Methods and Materials: A total of 656 patients were eligible. Patients with T3-4 N0-2 M0 or T1-2 N1-2 M0 resected, high-risk rectal cancer were randomly allocated to receive 5-FU by either protracted venous infusion or bolus during RT (50.4-54.0 Gy). Two cycles of bolus 5-FU were given before and after RT. One-half of the first 445 patients were also randomly allocated to receive lomustine in conjunction with the bolus 5-FU. The incidence and severity of diarrhea in relation to patient and treatment characteristics were evaluated. Results: The rate of diarrhea was significantly greater in patients receiving 5-FU by protracted venous infusion than in patients receiving bolus 5-FU; the difference was most pronounced for Grade 3 (severe) diarrhea (21% versus 13%, p=0.007). The incidence and magnitude of diarrhea before and after RT were similar. Patients treated with an anterior resection had a higher rate of severe or life-threatening diarrhea than did patients treated with an abdominoperineal resection (31% vs. 12%, p<0.001). Conclusions: During pelvic RT, patients who receive 5-FU by protracted venous infusion rather than by bolus have a higher risk of severe or life-threatening diarrhea during RT. This risk does not appear to persist during chemotherapy after completion of pelvic RT

  19. The ketogenic diet is an effective adjuvant to radiation therapy for the treatment of malignant glioma.

    Directory of Open Access Journals (Sweden)

    Mohammed G Abdelwahab

    Full Text Available INTRODUCTION: The ketogenic diet (KD is a high-fat, low-carbohydrate diet that alters metabolism by increasing the level of ketone bodies in the blood. KetoCal® (KC is a nutritionally complete, commercially available 4:1 (fat:carbohydrate+protein ketogenic formula that is an effective non-pharmacologic treatment for the management of refractory pediatric epilepsy. Diet-induced ketosis causes changes to brain homeostasis that have potential for the treatment of other neurological diseases such as malignant gliomas. METHODS: We used an intracranial bioluminescent mouse model of malignant glioma. Following implantation animals were maintained on standard diet (SD or KC. The mice received 2×4 Gy of whole brain radiation and tumor growth was followed by in vivo imaging. RESULTS: Animals fed KC had elevated levels of β-hydroxybutyrate (p = 0.0173 and an increased median survival of approximately 5 days relative to animals maintained on SD. KC plus radiation treatment were more than additive, and in 9 of 11 irradiated animals maintained on KC the bioluminescent signal from the tumor cells diminished below the level of detection (p<0.0001. Animals were switched to SD 101 days after implantation and no signs of tumor recurrence were seen for over 200 days. CONCLUSIONS: KC significantly enhances the anti-tumor effect of radiation. This suggests that cellular metabolic alterations induced through KC may be useful as an adjuvant to the current standard of care for the treatment of human malignant gliomas.

    Purpose: In patients with muscle-invasive bladder cancer, local-regional failure (LF) has been reported to occur in up to 20% of patients following radical cystectomy. The goals of this study were to describe patterns of LF, as well as assess factors associated with LF in a cohort of patients with pT3-4 bladder cancer. This information may have implications towards the use of adjuvant radiation therapy. Methods and Materials: Patients with pathologic T3-4 N0-1 bladder cancer were examined from an institutional radical cystectomy database. Preoperative demographics and pathologic characteristics were examined. Outcomes included overall survival and LF. Local-regional failures were defined using follow-up imaging reports and scans, and the locations of LF were characterized. Variables were tested by univariate and multivariate analysis for association with LF and overall survival. Results: A total of 334 patients had pT3-4 and N0-1 disease after radical cystectomy and bilateral pelvic lymph node dissection. Of these, 46% received perioperative chemotherapy. The median age was 71 years old, and median follow-up was 11 months. On univariate analysis, margin status, pT stage, and pN stage, were all associated with LF (P<.05), however, on multivariate analysis, only pT and pN stages were significantly associated with LF (P<.05). Three strata of risk were defined, including low-risk patients with pT3N0 disease, intermediate-risk patients with pT3N1 or pT4N0 disease, and high-risk patients with pT4N1 disease, who had a 2-year incidence of LF of 12%, 33%, and 72%, respectively. The most common sites of pelvic relapse included the external and internal iliac lymph nodes (LNs) and obturator LN regions. Notably, 34% of patients with LF had local-regional only disease at the time of recurrence. Conclusions: Patients with pT4 or N1 disease have a 2-year risk of LF that exceeds 30%. These patients may be the most likely to benefit from local adjuvant therapies.

    Background: The role of adjuvant postoperative therapy after resection of localised malignant melanoma involving regional lymph nodes remains controversial. There are no randomised trials that confirm that postoperative radiation conveys a benefit in terms of regional control or survival. Methods: Two hundred and thirty-four patients with melanoma involving lymph nodes were registered on a prospective study to evaluate the effect of postoperative radiation therapy. The regimen consisted of 48 Gy in 20 fractions to the nodal basin using recommended treatment guidelines for each of the major node sites. The primary endpoints were regional in-field relapse and late toxicity. Secondary endpoints were adjacent relapse, distant relapse, overall survival, progression-free survival and time to in-field progression. Results: Adjuvant radiation therapy was well tolerated by all of the patients. As the first site of relapse, regional in-field relapses occurred in 16/234 patients (6.8%). The overall survival was 36% at 5 years. The progression-free survival and regional control rates were 27% and 91%, respectively, at 5 years. Patients with more than 2 nodes involved had a significantly worse outcome in terms of distant relapse, overall and progression-free survival. Conclusion: We believe that adjuvant radiation therapy following nodal surgery could offer a possible benefit in terms of regional control. These results require confirmation in a randomised trial

    To investigate the effects of cognitive function on discontinuation of hormonal therapy in breast cancer survivors ages 65+ ("older"). Older breast cancer survivors with invasive, non-metastatic disease, and no reported cognitive difficulties were recruited from 78 Alliance sites between 2004 and 2011. Eligible survivors (n = 1280) completed baseline interviews; follow-up was conducted annually for up to 7 years. Survivors with estrogen-receptor-positive (ER+) cancers who initiated hormonal therapy (n = 990) were included. Self-reported cognitive function was measured using the EORTC-QLQ30 scale; a difference of eight points on the 0-100 scale was considered clinically significant. Based on varying rates of discontinuation over time, discontinuation was evaluated separately for three time periods: early (3-5 years). Cox models for each time period were used to evaluate the effects of cognition immediately preceding discontinuation, controlling for age, chemotherapy, and other covariates. Survivors were 65-91 years old (mean 72.6 years), and 79% had stages 1 or 2A disease. Overall, 43% discontinued hormonal therapy before 5 years. Survivors who reported lower cognitive function in the period before discontinuation had greater hazards of discontinuing therapy at the treatment midpoint (HR 1.22 per 8-point difference, CI 1.09-1.40, p cognition was not related to discontinuation in the other periods. Self-reported cognitive problems were a significant risk factor for discontinuation of hormonal therapy 1-3 years post-initiation. Additional research is needed on the temporality of cognitive effects and hormonal therapy to support survivorship care needs of older survivors.

    In a prospective randomized study, 434 MHz microwave therapy combined with external beam radiotherapy (VHF+RT) was compared with standard external beam radiotherapy (RT) in controlling locally recurrent or unresectable primary adenocarcinoma of the rectum. Independent assessors documented quality of life scores, performance status, toxicities local response to treatment, and systemic disease progression before treatment and after treatment and every 8 week thereafter. Of 75 patients randomized, 73 were eligible for inclusion in the study. Forty-three of these patients had local pelvic tumour recurrence only and 21 also had distant metastases. In addition, nine patients had primary inoperable carcinomas, two of whom also had metastases. Thirty-seven patients were randomized to RT and 36 to VHF+RT. Th median dose of radiation in the VHF+RT arm was 4275 cGy with a median fraction size of 150 cGy and median duration of therapy of 48.5 days versus 4500 cGy in the RT-only arm with a median fraction size of 180 cGy and median duration of therapy of 38 days. These doses are unlikely to be significantly different in biological effect. No significant difference between the two groups was observed in extent and duration of local control, measures of toxicity or quality of life scores. Additionally, survival and cumulative incidence of pelvic site of first progression did not differ significantly between the groups. It is concluded that VHF microwave therapy in conjunction with radiotherapy produces no therapeutic advantage over conventional radiation therapy alone in the treatment of locally recurrent rectal carcinoma. 35 refs., 8 tabs., 3 figs

    The aim of the work was to evaluate the prognostic importance of the sequence of radiotherapy (RT) and chemotherapy (CT) as adjuvant treatment in women with breast cancer who were treated with modified radical mastectomy or total mastectomy and their correlation also with other known prognostic factors. Methods: In this retrospective study, 200 women with breast cancer were evaluated. The age ranged from 25 to 73 years, with the mean age of 44 years; 125 patients had stage II and 75 had stage III disease. All were subjected to mastectomy. The influence of the following prognostic factors were evaluated: Age, histological grade, nodal status, number of positive nodes, tumor size, estrogen receptor status, menstrual status and as well as the sequence of radiotherapy and chemotherapy on 5-year locoregional disease free survival, 5-year systemic disease-free survival, and 5-year overall survival. Results: The 5-year locoregional disease free survival was 90.9% for the entire patient population. Nodal status, number of positive nodes and estrogen receptor status were prognostically significant for locoregional recurrence. The 5-year systemic disease-free survival was 67.6% for the whole group. On univariate analysis, the presence of positive axillary nodes, grade III tumor, ER-negative disease and radiotherapy first followed by chemotherapy, were independent poor risk factors for systemic recurrence. The 5-year overall survival was 71.8%. On univariate analysis, the presence of positive axillary nodes, grade III tumor, ER-negative disease and radiotherapy first followed by chemotherapy, were independent poor risk factors for death from breast cancer. Conclusions: In patients with breast cancer, a treatment protocol consisting of 6 cycles of CT followed by RT resulted in a better 5-year OS and DPS, and was easier to administer when compared with other treatment protocols. Ideal candidates are those with early-stage, age >35 years, low tumor grade, positive ER, and

    After surgical therapy of Achilles tendon rupture, neuromuscular changes may persist, even one year after surgery. We were interested whether these changes are also evident following a non-surgical functional therapy (Variostabil therapy boot/Adidas). Twenty-one patients with complete Achilles tendon rupture were enrolled in the study (mean age 38.5 years, range 24 to 60; 18 men, three women) and followed-up clinically and with surface EMG of the gastrocnemius muscles after four, eight, 12 weeks, and one year after rupture. EMG differences between the affected and non-affected side could only be observed at baseline and after four weeks following Achilles tendon rupture. The results from our study show that EMG changes are not found following non-surgical functional therapy.

    From 1971 through 1984, 320 women underwent radical hysterectomy as primary therapy of stage IB and IIA cervical cancer. Two hundred forty-eight patients (78%) were treated with surgery alone and 72 patients (22%) received adjuvant postoperative external-beam radiotherapy. Presence of lymph node metastasis, large lesion (greater than 4 cm in diameter), histologic grade, race (noncaucasian), and age (greater than 40 years) were significant poor prognostic factors for the entire group of patients. Patients treated with surgery alone had a better disease-free survival than those who received combination therapy (P less than 0.001). However, patients receiving adjuvant radiation therapy had a higher incidence of lymphatic metastases, tumor involvement of the surgical margin, and large cervical lesions. Adjuvant pelvic radiation therapy did not improve the survival of patients with unilateral nodal metastases or those who had a large cervical lesion with free surgical margins and the absence of nodal involvement. Radiation therapy appears to reduce the incidence of pelvic recurrences. Unfortunately, 84% of patients who developed recurrent tumor after combination therapy had a component of distant failure. The incidence of severe gastrointestinal or genitourinary tract complications was not different in the two treatment groups. However, the incidence of lymphedema was increased in patients who received adjuvant radiation therapy. Although adjuvant radiation therapy appears to be tolerated without a significant increase in serious complications, the extent to which it may improve local control rates and survival in high-risk patients appears to be limited. In view of the high incidence of distant metastases in high-risk patients, consideration should be given to adjuvant systemic chemotherapy in addition to radiation therapy.

  12. Platelet-rich plasma, an adjuvant biological therapy to assist peripheral nerve repair

    Full Text Available Therapies such as direct tension-free microsurgical repair or transplantation of a nerve autograft, are nowadays used to treat traumatic peripheral nerve injuries (PNI, focused on the enhancement of the intrinsic regenerative potential of injured axons. However, these therapies fail to recreate the suitable cellular and molecular microenvironment of peripheral nerve repair and in some cases, the functional recovery of nerve injuries is incomplete. Thus, new biomedical engineering strategies based on tissue engineering approaches through molecular intervention and scaffolding offer promising outcomes on the field. In this sense, evidence is accumulating in both, preclinical and clinical settings, indicating that platelet-rich plasma products, and fibrin scaffold obtained from this technology, hold an important therapeutic potential as a neuroprotective, neurogenic and neuroinflammatory therapeutic modulator system, as well as enhancing the sensory and motor functional nerve muscle unit recovery.

    Preoperative chemotherapy (PC) for operable breast cancer has shown significant benefits in prospective trials. Many patients are treated in the community setting and some may question the applicability of PC outside the university setting. Retrospective review was performed of stage II and IIIA breast cancer patients treated from January 2002 to July 2009. Fifty-three of 57 patients who underwent PC were matched based on age, tumor size, and hormone receptor status with 53 patients who did not undergo PC. Differences in patient compliance with physician recommendations for all types of adjuvant therapy were evaluated. Crude odds ratios and adjusted odds ratios derived from conditional logistic regression models were calculated. There were 106 patients included. Patient compliance with chemotherapy was better in the PC group than in the adjuvant chemotherapy (AC) group (100% versus 70%; p = .0001). Similarly, more patients in the PC group completed radiation therapy (96% versus 65%; p = .0003) and initiated hormonal therapy (100% versus 62%; p = .0001). Conditional logistic regression revealed that higher pathologic stage and current cigarette smoking were associated with poorer compliance with chemotherapy. For radiation therapy, the univariate model revealed that compliance with chemotherapy and being employed were associated with completion of radiation, whereas current cigarette smoking and larger pathologic size were associated with poorer compliance with radiation. For hormonal therapy, current cigarette smokers were more likely to be noncompliant with initiation of hormonal therapy. PC for operable breast cancer can improve patient compliance with chemotherapy. Current cigarette smokers were more likely to be noncompliant with all types of adjuvant therapy.

    Full Text Available The aim was to study the effect of combined probiotic containing Lactobacillus acidophilus, Bifidobacterium infantis, Enterococcus faecium, on H.pylori eradication efficacy in the treatment of children with chronic H.pylori- associated gastroduodenitis in the scheme of "triple" therapy of H.pylori eradication. Determination of total serum Ig M , A, G protein to Ag SagA H. pylori, breathing "Helik" test, rapid urease "Helpil" test ; that of concentration of serum sCD14 was conducted. The study group included 20 children who received standard "triple" eradication therapy for 7 days and 1 caps. of probiotic 3 times a day for 4 weeks, control group (20 children – who received only standard eradication therapy. It is shown that combined use of probiotics in the treatment of Helicobacter pylori infection enhances effectiveness of eradication of H.pylori. In the basis of action of probiotic strains of the drug is an anti-inflammatory effect mediated by the impact on non-specific mechanisms of innate immunity, provided by molecular mechanism responsible for induction of sCD14 synthesis.

    Purpose: To develop nomograms for predicting the overall survival (OS) and relapse-free survival (RFS) in patients with extrahepatic bile duct cancer undergoing adjuvant chemoradiation therapy after curative resection. Methods and Materials: From January 1995 through August 2006, a total of 166 consecutive patients underwent curative resection followed by adjuvant chemoradiation therapy. Multivariate analysis using Cox proportional hazards regression was performed, and this Cox model was used as the basis for the nomograms of OS and RFS. We calculated concordance indices of the constructed nomograms and American Joint Committee on Cancer (AJCC) staging system. Results: The OS rate at 2 years and 5 years was 60.8% and 42.5%, respectively, and the RFS rate at 2 years and 5 years was 52.5% and 38.2%, respectively. The model containing age, sex, tumor location, histologic differentiation, perineural invasion, and lymph node involvement was selected for nomograms. The bootstrap-corrected concordance index of the nomogram for OS and RFS was 0.63 and 0.62, respectively, and that of AJCC staging for OS and RFS was 0.50 and 0.52, respectively. Conclusions: We developed nomograms that predicted survival and recurrence better than AJCC staging. With caution, clinicians may use these nomograms as an adjunct to or substitute for AJCC staging for predicting an individual's prognosis and offering tailored adjuvant therapy.

    To examine the effect of mitomycin c and 5-flurouracil on treatment outcomes following Ahmed glaucoma valve implantation. Retrospective consecutive case series. Fifty patients who received Ahmed glaucoma valve implantation from 1999 to 2013 in the San Francisco Veterans Administration Hospital. The +INJECTION group received intraoperative mitomycin c followed by postoperative mitomycin c and/or 5-flurouracil, whereas the -INJECTION group did not. Primary outcome was treatment success at 1 year post-implantation. Intraocular pressure, hypertensive phase, and the number of glaucoma medications were also examined. Twenty-six patients/eyes in the +INJECTION group and 24 patients/eyes in the -INJECTION group were included. Treatment success was higher in the +INJECTION compared with the -INJECTION group (86 vs. 58%; P = 0.04). Intraocular pressure was lower in the +INJECTION compared with the -INJECTION group at 1, 3, 6 and 12 months (P ≪ 0.00001, P = 0.00003, 0.0008 and 0.024). Hypertensive phase occurred less often in the +INJECTION compared with the -INJECTION group (3.8 vs. 54%; P = 0.021). The +INJECTION group required fewer medications compared with the -INJECTION group (P = 0.02, 0.002, 0.003 and 0.008 at 1, 3, 6 and 12 months). Complication rates were comparable between groups (46.2 and 54.2%; P = 0.63). Adjuvant treatment with antifibrotics following Ahmed glaucoma valve implantation decreased the hypertensive phase and improved surgical outcomes without impacting complication rates at 1 year. This study postulates a role for antifibrotics in the postoperative management of Ahmed glaucoma valves. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

    Preoperative chemoradiotherapy followed by total mesorectal excision (TME) is the standard treatment for stage III lower rectal cancer worldwide. However, in Japan, the standard treatment is TME with lateral pelvic lymph node dissection (LPLD) followed by adjuvant chemotherapy. We examined the safety and efficacy of adjuvant therapy with oxaliplatin, leucovorin, and 5-fluorouracil (modified FOLFOX6) after TME with LPLD. This retrospective study included 33 patients who received modified FOLFOX6 after TME with LPLD for stage III lower rectal cancer. The overall completion rate of 12 cycles of adjuvant modified FOLFOX6 was 76%. Grade 3 or 4 neutropenia was observed in eight patients (24%). Sensory neuropathy was observed in 32 patients (97%) with 4 (12%) having a grade 3 event. The disease-free survival (DFS) rate was 45% at 3 years. Adjuvant modified FOLFOX6 was feasible in patients with stage III lower rectal cancer after TME with LPLD. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

    Purpose Several factors contribute to the pervasive Black-White disparity in breast cancer mortality in the U.S., such as tumor biology, access to care and treatments received including adjuvant hormonal therapy (AHT), which significantly improves survival for hormone-receptor positive breast cancers (HR+). We analyzed South Carolina Central Cancer Registry-Medicaid linked data to determine if, in an equal access health care system, racial differences in the receipt of AHT exist. Methods We evaluated 494 study-eligible, Black (n=255) and White women (n=269) who were under 65 years old and diagnosed with stages I–III, HR+ breast cancers between 2004 and 2007. Bivariate and multivariate analyses were conducted to assess receipt of ≥ 1 AHT prescriptions at any point in time following (ever-use) or within 12 months of (early-use) breast cancer diagnosis. Results Seventy-two percent of the participants were ever-users (70% Black, 74% White) and 68% were early-users (65% Black, 71% White) of AHT. Neither ever-use (adjusted OR (AOR)=0.75, 95% CI: 0.48–1.17) nor early-use (AOR=0.70, 95% CI: 0.46–1.06) of AHT differed by race. However, receipt of other breast cancer-specific treatments was independently associated with ever-use and early-use of AHT [ever-use: receipt of surgery (AOR= 2.15, 95% CI: 1.35–3.44); chemotherapy (AOR=1.97, 95% CI: 1.22–3.20); radiation (AOR=2.33, 95% CI: 1.50–3.63); early-use: receipt of surgery (AOR=2.03, 95% CI: 1.30–3.17); chemotherapy (AOR=1.90, 95% CI: 1.20–3.03); radiation (AOR=1.73, 95% CI: 1.14–2.63)]. Conclusions No racial variations in use of AHT among women with HR+ breast cancers insured by Medicaid in South Carolina were identified, but overall rates of AHT use by these women is low. Strategies to improve overall use of AHT should include targeting breast cancer patients who do not receive adjuvant chemotherapy and/or radiation. PMID:27120468

  19. Some Aspects Of Adjuvant Treatment Of Colorectal Cancer

    2008-01-01

    Colorectal cancer is one of the most common cancers in Europe and in North America. Cornerstone of the treatment of localized colorectal cancer is surgical resection followed by chemotherapy or radio-chemotherapy in indicated cases. For patients with Stage III colon cancer recent data have shown efficacy through the combining fluorouracil-based chemotherapy with oxaliplatin into adjuvant treatment program. For patients with Stage II colon cancer, the use of adjuvant chemotherapy remains controversial, but may be appropriate in a subset of individuals at high risk for disease recurrence. Current randomized clinical trials in the adjuvant therapy of colorectal cancer are examining the value of adding agents known to be active in metastatic disease, including those that modify specific molecular targets.

    The incidence of new primary cancers was evaluated in 3538 postmenopausal patients who had received surgical treatment for primary breast cancer. Of these patients, 1828 with a low risk of recurrence received no further treatment. High-risk patients were randomly assigned to one of two groups. The first group (n = 846) received postoperative radiotherapy, while the second group (n = 864) received radiotherapy plus tamoxifen at a dose of 30 mg given daily for 48 weeks. The median observation time was 7.9 years. In comparison with the number of new cancers in the general population, the number of new cancers in the three groups was elevated mostly due to a high number of cancers of the contralateral breast and of colorectal cancers in the high-risk groups. The cumulative risk of nonlymphatic leukemia was increased among patients who received postoperative radiotherapy (P = .04). Cancer incidence in the high-risk tamoxifen-treated group relative to that in the high-risk group not treated with tamoxifen was not significant (1.3). No protective effect of tamoxifen on the opposite breast was seen (rate ratio for breast cancer = 1.1), but a tendency to an elevated risk of endometrial cancer was observed (rate ratio = 3.3; 95% confidence interval = 0.6-32.4). Continued and careful follow-up of women treated with tamoxifen is necessary to clarify the potential cancer-suppressive or cancer-promoting effects of this drug

    Analysis is presented of a series of 256 human tumors treated under multifraction protocol regimes with standard controlled hyperthermia parameters and increasing doses of radiation therapy. Air cooled microwave applicators intracavitary and interstitial antennae operating at 915 or 300 MHz were used in various sites. Temperatures were measured by micro-thermocouples. Minimum tumor temperatures of 42 0 C were maintained at 1 hour, twice weekly. Treatment included a radiation dose of 1600-1700 rads. Tumor response was 94% with 60% or more total response. Frequency and duration of total responses depended mainly on the radiation dose. Skin tumors, melanomas, chest wall recurrences responded better than head and neck or intrapelvic recurrences. Side effects observed were minor burns; proctitis or oesophagitis with intracavitary devices; ulcerations or fistulae due to rapid tumor regression; 4 cases of pleuritis treating chest wall. Overall toxicity was less than 5%. In conclusion: 1) Combination heat-low dose radiation offers good palliation. 2) Response depends on radiation dose. 3) Combination of full dose radiation therapy plus hyperthermia proves to be well tolerated

    Full Text Available In the second half of the 20 century, echosonography has been used in many medical specialties. In 1992 and 1993 highfrequencies echosonography was used in the examination of irritant and allergic skin lesions in order to examine the effects of different therapeuthical agents on the skin lesions [1-4]. Hoffmann used highfrequencies echosonography in the examination of healing of skin lesions [3]. By their incidence skin tumors are the largest group of newly discovered tumors, and their usual location is on the face [5-7]. By clinical examination it is not possible to precisely determine the depth of tumor border; therefore, the radically performed surgical excision is the only correct surgical treatment. The aim of this study was to estimate the results of preoperatively performed high frequencies echosonography in order to reduce the number of incorrectly performed surgical excisions of skin tumors. The group was composed of 40 patients with 45 tumors, who first underwent echosonographic diagnostic procedure (20 MHz, Hadsund electronic, Hadsund Technology, Denmark and then surgical excision; patients in control group (45 patients with 45 tumors were only subjected to surgical excision. Excised tumors were then pathohistologically analyzed, and measurements of tumor depth progression were performed. Margins of pathohistological specimen were controlled for the presence of tumor cells. Results of measurements of tumor depth obtained by echosonography and pathohistological measurements were compared. By Jate's modification of c2 test results regarding correct and incorrect surgical excision in patients and control group were compared. By linear regression analysis results of tumor depth obtained by echosonographic and pathohistologic examinations were compared. Hypoechogen zone echosonographic results were used like criteria for tumor expansion. Results of tumor depth measurements are presented in Table 1. Linear regression analysis showed (R = 0

    Nonretroperitoneal abdominal soft tissue sarcoma (NRA-STS) is a rare disease with limited data supporting its management. Our study aimed to reveal the utilization patterns of adjuvant therapy and its potential survival benefits using the National Cancer Data Base. The analysis included patients with resected high-grade NRA-STS. Chi-square analysis was used to evaluate distribution of patient and tumor-related factors within treatment groups. The Kaplan-Meier and Cox proportional hazards model were utilized to evaluate overall survival according to treatment approach. Multivariate analysis was used to determine the impact of these factors on patients' outcome. Matched propensity score analysis was implemented to control for imbalance of confounding variables. At median follow-up of 49 months, 5-year overall survival improved from 46% without adjuvant radiation therapy to 52% (P = 0.009) with radiotherapy delivery with a 30% reduction in hazard of death (95% confidence interval = 0.58-0.84). On multivariate analysis, age <50, tumor <8 cm, negative margins and radiotherapy delivery were significant predictors of improved survival. Chemotherapy was not associated with significant survival improvement (Hazard Ratios [HR]: 0.89, P = 0.28). Adjuvant radiotherapy was associated with improved survival in high-grade NRA-STS. Chemotherapy was not associated with a survival improvement; however, further studies are needed to refine treatment strategies. © 2017 John Wiley & Sons Australia, Ltd.

    Full Text Available William Eardley, Cory TothDepartment of Clinical Neurosciences and the University of Calgary, Calgary, AB, CanadaAbstract: Although many therapies are used in the management of neuropathic pain (NeP due to polyneuropathy (PN, few comparison studies exist. We performed a prospective, non-randomized, unblended, efficacy comparison of the serotonin-norepinephrine reuptake inhibitor venlafaxine, as either monotherapy or adjuvant therapy, with a first-line medication for NeP, gabapentin, in patients with PN-related NeP. VAS pain scores were assessed after 3 and 6 months in intervention groups and in a cohort of patients receiving no pharmacotherapy. In a total of 223 patients, we analyzed pain quantity and quality (visual analogue scale [VAS] score, Brief Pain Inventory [BPI], quality of life and health status measures [EuroQol 5 Domains, EQ-5D], Medical Outcomes Sleep Study Scale [MOSSS], Hospital Anxiety and Depression Scale [HADS] and Short Form 36 Health Survey [SF-36] after 6 months of therapy. Significant improvements in VAS pain scores occurred for all treatment groups after 6 months. Improvements in aspects of daily life and anxiety were identified in all treatment groups. Our data suggest that monotherapy or adjuvant therapy with venlafaxine is comparable to gabapentin for NeP management. We advocate for head-to-head, randomized, double-blinded studies of current NeP therapies.Keywords: peripheral neuropathy, neuropathic pain, pharmacotherapy, venlafaxine, gabapentin

    Surgical paients have been known to benefit immensely from psychological interventions. This study set out to assess the pre and postoperative anxiety levels and depression and the effect of cognitive therapy among Nigerian surgical patients. The effects of gender and educational status on perioperative anxiety and depression were also evaluated. The study utilized a controlled outcome design to evaluate the efficacy of self-instructional training (SIT) and rational emotive therapy (RET) in surgical patients. Preoperative anxiety and depression scores were used as co-variants. Thirty-three (33) elective surgical patients were sampled randomly, divided into 3 groups of eleven (11) patients each. Eight (8) subjects underwent gynaecological procedures while the remaining 25 subjects had general surgical procedures. The mean age was 32.72 +/- 15.83 years (range = 17-16 years.) The major instruments used in the study were the State Anxiety Subscale of the Speilberger State Trait Anxiety Inventory (STAI) and Hospital Anxiety and Depression Inventory. SIT had the potential to reduce anxiety level among subjects postoperatively (t = 2.06; df = 10; p < 0.05). The use of RET reduced depression among surgical patients (t = 1.23; df = 10; p < 0.05). It was concluded that surgical patients manifest varying degrees of anxiety preoperatively and postoperatively. Patient's pre and postoperative anxiety and depression can be reduced by the introduction of SIT and RET.

    Breast cancer is the most common malignancy among women in the United States with the second highest incidence of cancer-related death following lung cancer. The decision-making process regarding adjuvant therapy is a time intensive dialogue between the patient and her oncologist. There are multiple tools that help individualize the treatment options for a patient. Population-based analysis with Adjuvant! Online and genomic profiling with Oncotype DX are two commonly used tools in patients with early stage, node-negative breast cancer. This case report illustrates a situation in which the population-based prognostic and predictive information differed dramatically from that obtained from genomic profiling and affected the patient's decision. In light of this case, we discuss the benefits and limitations of these tools.

    To better understand how physicians communicate with breast cancer patients about adjuvant endocrine therapy (AET), we explored, from the breast cancer patient's perspective, dimensions of the patient-provider communication among women who were on active AET treatment. Qualitative methods using semi-structured in-depth interviews were conducted with breast cancer patients (n = 22) who filled a prescription for AET in the previous 12 months. Interview questions aimed to elicit experiences with AET. We reviewed and coded interview transcripts using qualitative principles of inductive reasoning to identify concepts and themes from interview data. We grouped emergent themes into four major functions of physician-patient communication: (1) information exchange, (2) decision-making to take and continue AET, (3) enabling patient self-management and monitoring potential side effects, and (4) emotional support. Physicians exchanged information with patients in a way that they understood and enhanced patient's health literacy regarding the benefits and knowledge of AET. Physicians empowered patients to make decisions about their care. Patients expressed trust and confidence in their physician which helped them seek care when needed. Patients reported a high degree of self-efficacy to self-manage AET and were continuing treatment despite potential side effects. The results from our study suggest that women's interactions and communication with their physician may be an important factor that contributes to the continued use of AET. Physicians who can communicate information about AET treatment benefits, purpose, and expectations in a way that patients can understand is a critical aspect of care that needs to be further studied.

    Purpose: International consensus (IC) clinical target volumes (CTVs) have been proposed to standardize radiation field design in the treatment of patients at high risk of locoregional failure (LRF) after radical cystectomy. The purpose of this study was to externally validate the IC CTVs in a cohort of postsurgical patients followed up for LRF and identify revisions that might improve the IC CTVs' performance. Methods and Materials: Among 334 patients with pT3 to pT4 bladder cancer treated with radical cystectomy, LRF developed in 58 (17%), of whom 52 had computed tomography scans available for review. Images with LRF were exported into a treatment planning system, and IC CTVs were contoured and evaluated for adequacy of coverage of each LRF with respect to both the patient and each of 6 pelvic subsites: common iliac (CI) region, obturator region (OR), external and internal iliac region, presacral region, cystectomy bed, or other pelvic site. Revisions to the IC contours were proposed based on the findings. Results: Of the 52 patients with documented LRF, 13 (25%) had LRFs that were outside of the IC CTV involving 17 pelvic subsites: 5 near the CI CTV, 5 near the OR CTV, 1 near the external and internal iliac region, and 6 near the cystectomy bed. The 5 CI failures were located superior to the CTV, and the 5 OR failures were located medial to the CTV. Increasing the superior boundary of the CI to a vessel-based definition of the aortic bifurcation, as well as increasing the medial extension of the OR by an additional 9 mm, decreased the number of patients with LRF outside of the IC CTV to 7 (13%). Conclusions: Modified IC CTVs inclusive of a slight adjustment superiorly for the CI region and medially for the OR may reduce the risk of pelvic failure in patients treated with adjuvant radiation therapy.

    The aim is to evaluate the preliminary efficacy and side effects of paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy in combination with cisplatin hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) as postoperative adjuvant therapy for patients of locally advanced gastric cancer (GC) at high risk for recurrence after curative resection. Four GC patients who underwent radical gastrectomy with D2 lymphadenectomy were enrolled. All patients received paclitaxel 135 mg/m2 on day 1, 5-FU 500 mg/m2 on days 1-5, LV 200 mg/m2 on days 1-5 intravenous chemotherapy, cisplatin 75 mg/m2 on day 5, and HIPEC one month after surgery. It was repeated at 3 weeks intervals and at least two cycles administered. A total of 181 cycles of chemotherapy were administered (median, 4 cycles). The median disease free survival time of patients was 40.8 months. The median overall survival time was 48.0 months. The one-, two-, and three-year recurrence rates were 14.6%, 26.8%, and 46.3%, respectively. The main relapse patterns were remnant GC and metastases of retroperitoneal lymph nodes. The morbidity of grade 3 and 4 toxicities of myelosuppression, nausea/ vomiting were less than 10%. The side effects of grade 1 and 2 of hematologic toxicity, nausea and vomiting, abnormal function of liver, kidney or cardiac, fatigue and neurotoxicity were well tolerated. Cisplatin HIPEC combined with paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy regimen could improve the survival rate and decrease the postoperative recurrence of locally advanced GC.

    The benefit of a sentinel lymph node (SLN) biopsy and adjuvant therapy for patients with thick (>4 mm) melanoma has not been well studied in the Asian population. We examined the benefit of an SLN biopsy and adjuvant therapy on prognosis in Japanese patients with thick melanoma. A review of the melanoma database collected from 26 institutions in Japan identified 291 patients with thick melanoma between 2005 and 2010. Univariate and multivariate analyses were performed to evaluate the factors predictive of the overall survival (OS) and the disease-free survival (DFS). Of the 242 patients with thick melanoma who underwent an SLN biopsy, the results for 96 (40%) were positive. On multivariate analysis, increased Breslow thickness (relative risk, 1.11; 95% confidence interval, 1.05-1.17; P=0.0002) and SLN metastasis (2.14; 1.04-4.43; P=0.040) were associated with a poor OS. Increased Breslow thickness (1.11; 1.04-1.18; P =0.0018), ulceration (3.11; 1.25-7.72; P=0.014), satellitosis (3.89; 1.62-9.31; P=0.0023), and SLN metastasis (2.24; 1.16-4.36; P=0.017) were associated with DFS. Adjuvant chemotherapy had no impact on either OS or DFS. Adjuvant use of a monthly dermal injection of interferon-β (IFN-β) was associated with a improvement in both OS (0.34; 0.17-0.67; P=0.0022) and DFS (0.42; 0.20-0.86; P=0.018). An SLN biopsy provided useful prognostic information and the adjuvant use of IFN-β improved both OS and DFS in Japanese patients with thick melanoma. These results were consistent with those of previous studies carried out on a white population. Therefore, we suggest that an SLN biopsy and adjuvant IFN should be considered for patients with thick melanoma irrespective of the Breslow thickness or ethnicity.

    Full Text Available Background: Rituximab, a monoclonal anti-CD20 antibody, has been used with encouraging results in pemphigus. We describe herein refractory cases of pemphigus vulgaris (n = 23 and pemphigus foliaceus (n = 1 treated with rituximab in addition to steroids and immunosuppressants. Aims: To assess the response to treatment, the duration of clinical remission, serology of the response and adverse effects of rituximab in pemphigus patients. Methods: We recorded observations of 24 patients with pemphigus having either refractory disease in spite of high dose of steroids and immunosuppressants, corticosteroid-dependent disease, strong contraindications to corticosteroids, or severe disease. The patients were treated with infusions of one injection per week for three consecutive weeks of 375 mg of rituximab per m 2 of body-surface area. One similar infusion was repeated after 3 months of 3 rd dose. We observed the clinical outcome after 6 months of 3 rd dose of rituximab and looked for complete healing of cutaneous and mucosal lesions (complete remission. Observations: After follow-up of 7-24 months, five patients showed only partial improvement while 19 of 24 patients had a complete remission 3 months after rituximab. Of these 19 patients, 12 patients achieved complete remission and are off all systemic therapy, and the rest are continuing with no or low dose of steroids with immunosuppressants. Two patients relapsed after initial improvement; one was given moderate dose of oral steroids and immunosuppressant and the other was given repeat single dose of rituximab to control relapse. Conclusion: Rituximab is able to induce a prolonged clinical remission in pemphigus after a single course of four infusions. The high cost and limited knowledge of long term adverse effects are limitations to the use of this biologic agent.

    Primary intestinal lymphangiectasia (PIL) is a protein-losing, exsudative gastroenteropathy causing lymphatic obstruction. Diagnosis depends on clinical examination and histological findings. Conservative treatment modalities include a low-fat diet and enteral nutritional therapy in order to reduce enteric protein loss and to improve fat metabolism. Other treatment options consist of administration of antiplasmin or octreotide to lower lymph flow and secretion. We report on a 58-year-old patient who underwent exploratory laparotomy due to a worsening physical status, recurrent chylaskos and leg oedema under conservative dietary therapy. Intraoperative findings showed a typical PIL of the jejunum about 20 cm distal to the Treitz's ligament. Histological examinations confirmed this diagnosis. One year after segmental small bowel resection (105 cm) with end-to-end anastomosis the patient is healthy, free of symptoms, has gained weight and his serum protein level has increased. Intraabdominal ascites and leg oedema have not reoccurred since.

    Full Text Available Objective: To explore the effect of the adjuvant milrinone therapy on cardiac function, myocardial remodeling and RAAS system activity in patients with chronic heart failure. Methods: A total of 110 patients with chronic heart failure who were treated in the hospital between January 2015 and January 2017 were divided into control group (n=55 and observation group (n=55 by random number table method. Control group received conventional therapy for chronic heart failure, and the observation group received milrinone on the basis of conventional therapy. The differences in ultrasound cardiac function and myocardial remodeling index levels as well as serum RAAS index contents were compared between the two groups before and after treatment. Results: Before treatment, the differences in ultrasound cardiac function and myocardial remodeling index levels as well as serum RAAS index contents were not statistically significant between the two groups. After treatment, CO and SV levels of both groups of patients were significantly higher than those before treatment while LADd, LVEDd, LVPWT, IVST and LVMI levels as well as serum PRA, AngⅡ and ALD contents were significantly lower than those before treatment, and CO and SV levels of observation group were significantly higher than those of control group while LADd, LVEDd, LVPWT, IVST and LVMI levels as well as serum PRA, AngⅡ and ALD contents were significantly lower than those of control group. Conclusion: Adjuvant milrinone therapy can effectively enhance the cardiac function, inhibit the myocardial remodeling and decrease the RAAS system activity in patients with chronic heart failure.

    One of the first chemoprevention trials conducted in the western hemisphere, the National Surgical Adjuvant Breast and Bowel Project's (NSABP) Breast Cancer Prevention Trial (BCPT), demonstrated the need to evaluate all aspects of recruitment in real time and to implement strategies to enroll racial and ethnic minority women. The purpose of this report is to review various patient recruitment efforts the NSABP developed to enhance the participation of racial and ethnic minority women in the Study of Tamoxifen and Raloxifene (STAR) trial and to describe the role that the recruitment process played in the implementation and understanding of breast cancer risk assessment in minority communities. The NSABP STAR trial was a randomized, double-blinded study comparing the use of tamoxifen 20 mg/day to raloxifene 60 mg/day, for a 5-year period, to reduce the risk of developing invasive breast cancer. Eligible postmenopausal women were required to have a 5-year predicted breast cancer risk of 1.66% based on the modified Gail Model. For the current report, eligibility and enrollment data were tabulated by race/ethnicity for women who submitted STAR risk assessment forms (RAFs). A total of 184,460 RAFs were received, 145,550 (78.9%) from white women and 38,910 (21.1%) from minority women. Of the latter group, 21,444 (11.6%) were from African Americans/blacks, 7913 (4.5%) from Hispanics/Latinas, and 9553 (5.2%) from other racial or ethnic groups. The percentages of risk-eligible women among African Americans, Hispanics/Latinas, others, and whites were 14.2%, 23.3%, 13.7%, and 57.4%, respectively. Programs targeting minority enrollment submitted large numbers of RAFs, but the eligibility rates of the women referred from those groups tended to be lower than the rates among women referred outside of those programs. The average number of completed risk assessments increased among minority women over the course of the recruitment period compared to those from whites. We have not

    A number of techniques are available for the correction of gynecomastia. Nonscarring sparing methods are preferred, and the minimally invasive technique is to use liposuction for the gland and the fatty tissue exclusively. In this retrospective study we present our experience with a combination of liposuction and subsequent resection of the remaining gland. Sixty-two patients (112 breasts) were surgically treated for gynecomastia from January 1996 and September 2000. From 1996 to 1997 all patients suffering from gynecomastia grade Simon I-II were treated by the method described by Rosenberg and Stark, which is exclusively suction of the fatty and glandular tissue. In a retrospective chart study a high recurrence rate was found in these patients. Subsequently we changed our technique to liposuction of the fatty tissue followed by sharp excision of the glandular tissue through the incision made for the liposuction cannula in the submammary fold. Suction alone was not sufficient to remove the glandular tissue; the rate of recurrence after suction was 35%. When sharp resection of the glandular tissue was carried out after the liposuction the recurrence rate dropped to under 10%. In total our complication rate was 50% including minor sequelae. The most frequent complication was unacceptable scarring of the nipple-areola complex. Hypesthesia of the nipple-areola occurred in 13.4% of the patients. The combination of liposuction and resection of the glandular tissue is a minimally invasive correction that can be used in all cases of gynecomastia grade Simon I-II.

    Surgery for carcinoma of the oral cavity has developed rapidly with recent advances in reconstruction. Particularly, in radical surgery for progressive and recurrent disease, safe and adequate resection has been made possible and postoperative cosmetic and functional recovery has been achieved. We reviewed 64 patients with progressive and recurrent cancer who had undergone reconstruction using microvascular techniques during the 12 years from 1983 to 1994. There were 19 patients with T3 disease, 25 with T4 disease, and 20 with recurrence. The free grafts used were radial forearm flaps, the jejunum, rectus abdominis musculocutaneous flaps, and scapular flaps. The survival of free flap grafts was 95.3%. The primary tumor control rate was 85.9%, and the 5-year cumulative survival rate was 61.1%, 60.1%, and 62.9% for patients with T3, T4, and recurrent disease, respectively. Twelve patients with T4 disease of the tongue and the floor of the mouth were treated with combined preoperative brachytherapy and surgery to alleviate postoperative dysfunction, and this treatment was found to be exceedingly effective for improving the postoperative quality of life. There are still many problems with mandibular reconstruction. Since cancer patients commonly undergo preoperative radiotherapy, transplantation of living vascularized bone grafts is frequently performed and is believed to be effective. Since it is important to reconstruct masticatory function as well as to achieve cosmetic improvement, various techniques have recently been used to fit the reconstructed mandible with dental prostheses in order to restore masticatory function. This paper describes the present status and the prospects of surgical therapy for oral cancer. (author)

    Pneumatic balloon dilation and surgical myotomy are the most effective treatments for achalasia. While there is controversy which method is best, the aim of the current study was to identify predictors of symptom recurrence after endoscopic or surgical therapy. Patients undergoing pneumatic balloon dilatation (30mm) or laparoscopic Heller myotomy with Dor fundoplication were included in the study. Analyzed parameters include total symptom score (sum of 0-5 point intensity for dysphagia, regurgitation and chest pain), width and height of esophageal column at 2 and 5 minutes after oral barium ingestion, lower esophageal sphincter (LES) length, resting (LESP) and residual pressure (LESRP) before and 3 months after intervention. Patients with symptoms score surgical group were symptom-free 3 months after intervention. Therapies improved LESP (24.4±8.2mmHg pre- vs. 15.4±10.3mmHg post-therapy; p=0.003) and mean LESRP (7.9±4.3mmHg pre- vs. 5.3±6.7mmHg post-therapy; p=0.03). Univariate linear regression analysis identified barium contrast column width >5cm at 2 minutes (p=0.04), LES length 10mmHg (p=0.02) as predictors for persistent symptoms. While >85% of achalasia patients responded well to 30mm pneumatic balloon dilation, patients with elevated LES pressure, short LES and wide esophagus should be considered as primary surgical candidates.

    Engineered stem cell (SC)-based therapy holds enormous promise for treating the incurable brain cancer glioblastoma (GBM). Retaining the cytotoxic SCs in the surgical cavity after GBM resection is one of the greatest challenges to this approach. Here, we describe a biocompatible electrospun nanofibrous scaffold (bENS) implant capable of delivering and retaining tumor-homing cytotoxic stem cells that suppress recurrence of post-surgical GBM. As a new approach to GBM therapy, we created poly(l-lactic acid) (PLA) bENS bearing drug-releasing human mesenchymal stem cells (hMSCs). We discovered that bENS-based implant increased hMSC retention in the surgical cavity 5-fold and prolonged persistence 3-fold compared to standard direct injection using our mouse model of GBM surgical resection/recurrence. Time-lapse imaging showed cytotoxic hMSC/bENS treatment killed co-cultured human GBM cells, and allowed hMSCs to rapidly migrate off the scaffolds as they homed to GBMs. In vivo, bENS loaded with hMSCs releasing the anti-tumor protein TRAIL (bENSsTR) reduced the volume of established GBM xenografts 3-fold. Mimicking clinical GBM patient therapy, lining the post-operative GBM surgical cavity with bENSsTR implants inhibited the re-growth of residual GBM foci 2.3-fold and prolonged post-surgical median survival from 13.5 to 31 days in mice. These results suggest that nanofibrous-based SC therapies could be an innovative new approach to improve the outcomes of patients suffering from terminal brain cancer. PMID:27016620

    To explore the efficacy of mindfulness-
based music therapy (MBMT) to improve attention and decrease mood distress experienced by women with breast cancer receiving adjuvant chemotherapy. Quantitative, descriptive, longitudinal approach. A comprehensive cancer hospital and a university in southern Florida. 15 women with a diagnosis of breast cancer, stages I-III, receiving adjuvant chemotherapy. Participants individually received MBMT for one hour per week for four weeks. The sessions consisted of varied music activities accompanied by mindfulness attitudes, or mental strategies that enhance moment-to-moment awareness, and weekly homework. Demographic information was collected at baseline. Attention was measured using Conners' Continuous Performance Test II. Mood was measured using the Profile of Mood States-Brief Form. Narrative comments collected from the homework assignments served to reinforce quantitative data. Repeated measures analysis of variance showed that attention improved significantly over time. Although all mood states significantly improved from the beginning to the end of each MBMT session, the mood state of fatigue decreased significantly more than the other mood states. MBMT enhances attention and mood, particularly the mood state of fatigue, in women with breast cancer receiving adjuvant chemotherapy. 
. A preferred music listening and mindfulness exercise may be offered to women with breast cancer who experience attention problems and mood distress.

Demographic data such as cause of corneal perforation, surgical procedures, and visual outcomes were retrospectively analyzed.Results: The causes of corneal perforation (n=31 were divided into infectious (n=8, 26% and noninfectious (n=23, 74% categories. Infectious causes included fungal ulcer, herpetic stromal necrotizing keratitis, and bacterial ulcer. The causes of noninfectious keratopathy included corneal melting after removal of a metal foreign body, severe dry eye, lagophthalmos, canaliculitis, the oral anticancer drug S-1, keratoconus, rheumatoid arthritis, neurotrophic ulcer, atopic keratoconjunctivitis, and unknown causes. Initial surgical procedures included central large corneal graft (n=17, small corneal graft (n=7, and amniotic membrane transplantation (n=7. In two cases the perforation could not be sealed during the first surgical treatment and required subsequent procedures. All infectious keratitis required central large penetrating keratoplasty to obtain anatomical cure. In contrast, several surgical options were used for the treatment of noninfectious keratitis. After surgical treatment, anatomical cure was obtained in all cases. Mean postoperative best corrected visual acuity was better at 6 months (logMAR 1.3 than preoperatively (logMAR 1.8.Conclusion: Surgical therapies for corneal perforations in our hospital included central large lamellar/penetrating keratoplasty, small peripheral patch graft, and amniotic membrane transplantation.

    Full Text Available Background: treatment guidelines for ulcerative colitis (UC not yet established. Currently, mesalazine, corticosteroids, and immunomodulators are treatment options for UC. However, they are known to have unpleaseant side effects such as nausea, vomiting, headaches, hepatitis, and male infertility. Curcumin is found in Turmeric plants (Curcuma longa L., which possesses both anti-inflammatory and antioxidant properties. This study aimed to determine whether curcumin as adjuvant therapy can induce or maintain remission in UC patients. Methods: structured search in three database (Cochrane, PubMed, Proquest using “Curcumin”, “remission” and “Ulcerative Colitis” as keywords. Inclusion criteria is randomized controlled trials (RCTs, meta-analysis, or systematic review using curcumin as adjuvant therapy in adult UC patients. Results: we found 49 articles. After exclusion, three RCTs were reviewed; two examined curcumin efficacy to induce remission and one for remision maintenance in UC. Curcumin was significantly more effective than placebo in all RCTs. The efficacy of curcumin could be explained by its anti-inflammatory properties, which inhibit NF-kB pathway. Regulation of oxidant/anti-oxidant balance can modify the release of cytokines. However, methods varied between RCTs. Therefore, they cannot be compared objectively. Futhermore, the sample size were small (n= 50, 45, 89 therefore the statistical power was not enough to generate representative results in all UC patients. Conclusion: Available evidence showed that curcumin has the potential to induce and maintain remission in UC patients with no serious side effects. However, further studies with larger sample size are needed to recommend it as adjuvant therapy of ulcerative colitis.

  5. Breast and other cancer dormancy as a therapeutic endpoint: speculative recombinant T cell receptor ligand (RTL) adjuvant therapy worth considering?

    Most individuals who died of trauma were found to harbour microscopic primary cancers at autopsies. Surgical excision of the primary tumour, unfortunately, seems to disturb tumour dormancy in over half of all metastatic relapses. A recently developed immune model suggested that the evolutionary pressure driving the creation of a T cell receptor repertoire was primarily the homeostatic surveillance of the genome. The model is based on the homeostatic role of T cells, suggesting that molecular complementarity between the positively selected T cell receptors and the self peptide-presenting major histocompatibility complex molecules establishes and regulates homeostasis, strictly limiting variations of its components. The repertoire is maintained by continuous peripheral stimulation via soluble forms of self-peptide-presenting major histocompatibility complex molecules governed by the law of mass action. The model states that foreign peptides inhibit the complementary interactions between the major histocompatibility complexes and T cell receptors. Since the vast majority of clinically detected cancers present self-peptides the model assumes that tumour cells are, paradoxically, under homeostatic T cell control. The novelty of our hypothesis therefore is that resection of the primary tumour mass is perceived as loss of 'normal' tissue cells. Consequently, T cells striving to reconstitute homeostasis stimulate rather than inhibit the growth of dormant tumour cells and avascular micrometastases. Here we suggest that such kick-start growths could be prevented by a recombinant T cell receptor ligand therapy that modifies T cell behaviour through a partial activation mechanism. The homeostatic T cell regulation of tumours can be tested in a tri-transgenic mice model engineered to express potent oncogenes in a doxycycline-dependent manner. We suggest seeding dissociated, untransformed mammary cells from doxycycline naïve mice into the lungs of two mice groups: one

    Full Text Available Purpose Lower urinary tract dysfunction is the most common complication after radical pelvic surgery. The aims of this study were to assess the effect of radical hysterectomy (RH on the storage function of the lower urinary tract and to evaluate the impact of radiation therapy (RT on postoperative urodynamic parameters. Methods This was a retrospective review of preoperative and postoperative urodynamic variables, which were prospectively collected. All women from 2006 to 2008, who underwent RH for uterine cervical cancer with a stage of 1A to 2B with or without adjuvant RT were enrolled. All patients were divided into two groups: group 1, without RT, and group 2, with adjuvant RT. Urodynamic studies were performed before, 10 days after, and 6 months after RH. Results A total of 42 patients with a mean (±standard error age of 51.9 (±12.3 years were analyzed. There were no significant differences in age, body mass index or clinical stage between the two groups. On the 10th postoperative day, all parameters were decreased except postvoid residual volume. In comparison with group 2 (n=14, group 1 (n=28 showed a significant increase in bladder compliance. At 6 months postoperatively, bladder compliance in group 1 had increased four times or more compared with that on postoperative 10 days. However, it had increased only 2.5 times in group 2 at the same time point (P<0.001. Conclusions The results of our study suggest that adjuvant RT after RH might result in a deterioration of bladder compliance. It is highly suggested that practitioners pay attention to low bladder compliance, especially in patients who have adjuvant RT after RH.

    Factors determining recurrence of nonfunctioning pituitary adenomas (NFAs) that require further therapy are unclear as are postoperative follow-up imaging guidelines. We aimed to identify predictors for secondary therapy after surgical resection of NFAs and use this knowledge to inform postoperative management. A single-centre retrospective study of surgically resected NFAs in 108 patients followed for up to 15 years. Serial tumour images were analysed for size, location and growth rate (GR) and tissue analysed for hormone cell type and proliferation indices with secondary treatment as outcome measure. Twenty-four of 66 (36%) patients harbouring a postoperative remnant required secondary treatment, all occurring within 10 years. No secondary treatment was required in any of 42 patients with complete tumour resection. Age, gender, remnant volume and tumour histology were not different between patients requiring and not requiring secondary therapy. Remnant GRs in those requiring secondary therapy were more than 10-fold higher (Prisk for secondary therapy. Tumour GR in the first three postoperative years correlated significantly (r 2 =.6, P<.01) with GR during the period of follow-up. In surgically resected NFAs further treatment is dependent on the presence of residual tumour, growth rate and location but not tumour histology. Postoperative growth rate of NFAs in the first 3 years of imaging can be used to tailor long-term follow-up to optimize use of health resources. © 2017 John Wiley & Sons Ltd.

    This paper presents long-term results from a randomized trial of pre- or postoperative megavoltage radiation therapy versus surgery alone in pre- and postmenopausal women with operable breast cancer. Treatment outcome after relapse among patients who developed loco-regional recurrences was also analyzed. A total of 960 patients were included in the trial. The mean follow-up was 16 years (range: 13-19 years). The radiation therapy was individually planned. It included the chest wall (and the breast in the preoperative cases) and the regional lymph nodes. The tumor dose was 45 Gy/5 weeks. No adjuvant systemic therapy was used. The results showed a significant benefit with radiation therapy in terms of recurrence-free survival during the entire follow-up period. There was also an overall survival difference-corresponding to a 16% reduction of deaths-in favor of the irradiated patients which, however, was not statistically significant (p = 0.09). Among those 169 patients who developed locoregional recurrences long-term control was only achieved in about one-third of the cases. This figure was similar among those who had received adjuvant radiation therapy (34%) compared to those initially treated with surgery alone (32%). This implied that the overall proportion of patients who eventually developed uncontrolled local disease was significantly higher among those initially allocated to surgery alone (16%) compared to those allocated to pre- or postoperative radiation therapy (6%, p < 0.01). These results suggest that local undertreatment may be deleterious in subgroups of patients.

    The role of chemotherapy in high-risk soft tissue sarcoma is controversial. Though many patients undergo initial curative resection, distant metastasis is a frequent event, resulting in 5-year overall survival rates of only 50-60%. Neo-adjuvant and adjuvant chemotherapy (CTX) has been applied to achieve pre-operative cytoreduction, assess chemosensitivity, and to eliminate occult metastasis. Here we report on the results of our non-randomized phase II study on neo-adjuvant treatment for high-risk STS. Patients with potentially curative high-risk STS (size ≥ 5 cm, deep/extracompartimental localization, tumor grades II-III [FNCLCC]) were included. The protocol comprised 4 cycles of neo-adjuvant chemotherapy (EIA, etoposide 125 mg/m(2) iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m(2) day 1, pegfilgrastim 6 mg sc day 5), definitive surgery with intra-operative radiotherapy, adjuvant radiotherapy and 4 adjuvant cycles of EIA. Between 06/2005 and 03/2010 a total of 50 subjects (male = 33, female = 17, median age 50.1 years) were enrolled. Median follow-up was 30.5 months. The majority of primary tumors were located in the extremities or trunk (92%), 6% originated in the abdomen/retroperitoneum. Response by RECIST criteria to neo-adjuvant CTX was 6% CR (n = 3), 24% PR (n = 12), 62% SD (n = 31) and 8% PD (n = 4). Local recurrence occurred in 3 subjects (6%). Distant metastasis was observed in 12 patients (24%). Overall survival (OS) and disease-free survival (DFS) at 2 years was 83% and 68%, respectively. Multivariate analysis failed to prove influence of resection status or grade of histological necrosis on OS or DFS. Severe toxicities included neutropenic fever (4/50), cardiac toxicity (2/50), and CNS toxicity (4/50) leading to CTX dose reductions in 4 subjects. No cases of secondary leukemias were observed so far. The current protocol is feasible for achieving local control rates, as well as OS and DFS comparable to previously published

    Objective: To investigate the causes of failure in treating atrial septal defect (ASD) and ventricular septal defect (VSD) with interventional procedures and to evaluate the clinical efficacy of surgical treatment in order to increase the successful rate. Methods: A total of 13 patients, who underwent surgical therapy because of unsuccessful interventional treatment for ASD or VSD during the period of January 2001-December 2007, were selected,and the clinical data were retrospectively analyzed. The surgical indications included the occluder abscission (n=7), III degree atrioventricular conduction block (n=3), valvular regurgitation (n=2), residual shunt (n=1) and interventional failure (n=1). The cardiac surgeries, including removal of the displaced occluder and / or the repair of atrioventricular septal defects, were performed with the help of cardiopulmonary bypass in all 13 cases. After surgical treatment, all patients were transferred into ICU for further supervision and treatment. Results: The average diameter of ASD on surgical exploration was 31 mm, which was greater than the preoperative average diameter (26 mm), with a significant difference (P 0.05). The III degree atrioventricular conduction block in 3 cases restored sinus rhythm after operation. All the procedures were successfully completed in all patients. No death occurred during the hospitalization period. Conclusion: Proper and timely cardiac surgery is an effective and safe measure for the treatment of the complications due to unsuccessful interventional therapy as well as the atrioventricular septal defect itself.

    Purpose: Positive surgical margins after radical vulvectomy for vulvar cancer portend a high risk for local relapse, which may be challenging to salvage. We assessed the impact of adjuvant radiation therapy (aRT) on overall survival (OS) and the dose-response relationship using the National Cancer Data Base. Methods and Materials: Patients with vulvar squamous cell carcinoma who underwent initial extirpative surgery with positive margins from 1998 to 2012 were included. Factors associated with aRT and specific dose levels were analyzed using logistic regression. Log-rank and multivariable Cox proportional hazards modeling were used for OS analysis. Results: We identified 3075 patients with a median age of 66 years (range, 22-90 years); the median follow-up time was 36.4 months (interquartile range [IQR] 15.4-71.0 months). Stage IA/B disease represented 41.2% of the cohort. Sixty-three percent underwent lymph node assessment, with a 45% positivity rate. In total, 1035 patients (35.3%) received aRT, with a median dose of 54.0 Gy (IQR 48.6-60.0 Gy). The 3-year OS improved from 58.5% to 67.4% with aRT (P<.001). On multivariable analysis, age, Charlson-Deyo score ≥1, stage ≥II, tumors ≥4 cm, no aRT, and adverse nodal characteristics led to inferior survival. Dose of aRT was positively associated with OS as a continuous variable on univariate analysis (P<.001). The unadjusted 3-year OS for dose subsets 30.0 to 45.0 Gy, 45.1 to 53.9 Gy, 54.0 to 59.9 Gy, and ≥60 Gy was 54.3%, 55.7%, 70.1%, and 65.3%, respectively (P<.001). Multivariable analysis using a 4-month conditional landmark revealed that the greatest mortality reduction occurred in cumulative doses ≥54 Gy: 45.1 to 53.9 Gy (hazard ratio [HR] 0.94, P=.373), 54.0 to 59.9 Gy (HR 0.75, P=.024), ≥60 Gy (HR 0.71, P=.015). No survival benefit was seen with ≥60 Gy compared with 54.0 to 59.9 Gy (HR 0.95, P=.779). Conclusions: Patients with vulvar squamous cell carcinoma and positive surgical

    Altogether 324 patients with skin basilomas, 559 with recurrent basiloma and 38 with squamous-cell carcinoma of the skin were treated by means of impulse neodymium laser radiation. A follow-up period was up to 7 years. It was shown that impulse laser radiation is a highly effective means of treating skin cancer, having a number of advantages over the radiation and surgical methods. Laser radiation is also highly effective in the treatment of basiloma relapses. If relapses accounted for by the development of a radioresistant tumour occur at the sites where surgical eXcision yields an unstatisfactory cosmetic effect, laser therapy should be considered a method of choice

    Despite the controversy regarding clinical efficacy, dental hygienists use the diode laser as an adjunct to non-surgical periodontal therapy. The technique to maximize successful laser therapy outcome is controversial as well. The purpose of this review is to explore the scientific foundation of the controversy surrounding the use of the diode laser as an adjunct to non-surgical periodontal therapy. Further, this paper addresses the weaknesses in study design, the heterogeneity of methodology in the published clinical studies, especially the laser parameters, and how these issues impact the collective clinical and microbial data, and thus conclusions regarding clinical efficacy. Evaluation of the literature identifies possible mechanisms that could contribute to the varied, often conflicting results among laser studies that are the foundation of the controversy surrounding clinical efficacy. These mechanisms include current paradigms of periodontal biofilm behavior, tissue response to laser therapy being dependent on tissue type and health, and that the successful therapeutic treatment window is specific to the target tissue, biofilm composition, laser wavelength, and laser energy delivered. Lastly, this paper discusses laser parameters used in the various clinical studies, and how their diversity contributes to the controversy. Although this review does not establish clinical efficacy, it does reveal the scientific foundation of the controversy and the need for standardized, well designed randomized controlled clinical trials to develop specific guidelines for using the laser as an adjunct to non-surgical periodontal therapy. Using evidence-based laser guidelines would allow dental hygienists to provide more effective non-surgical periodontal care.

    Purpose Assess the effectiveness of an orofacial myofunctional therapeutic program in patients with oral or oropharyngeal cancer submitted to adjuvant radiotherapy through pre- and post-program comparison of maximum mandibular opening. Methods Prospective study involving five adult patients and five elderly patients postoperatively to oral cavity/oropharynx surgery who were awaiting the beginning of radiotherapy or had undergone fewer than five treatment sessions. The study participants had their maximum jaw opening measured using a sliding caliper at the beginning and end of the program. Two mobility exercises and three mandibular traction exercises were selected and weekly monitored presentially for 10 weeks. Descriptive data and pre- and post-therapy comparative measures were statistically analyzed using the Wilcoxon test. Results Ten patients (two women and eight men) with mean age of 58.4 years, median of 57.0 years, completed the therapeutic program. They presented mean maximum mandibular opening of 31.6 ± 11.7 and 36.4 ± 8.0 mm pre- and post-therapy, respectively (p =0.021). Conclusion The proposed orofacial myofunctional therapeutic program increased the maximum jaw opening of patients referred to adjuvant radiotherapy for oral cavity or oropharynx cancer treatment.

    Background. Phase III trials of rehabilitation of paresis after stroke have proven the effectiveness of intensive and extended task practice, but they have also shown that many patients do not qualify, because of severity of impairment, and that many of those who are treated are left with clinically significant deficits. Objective. To test the value of 2 potential adjuvants to normal learning processes engaged in constraint-induced movement therapy (CIMT): greater distribution of treatment over time and the coadministration of d-cycloserine, a competitive agonist at the glycine site of the N-methyl-D-aspartate glutamate receptor. Methods. A prospective randomized single-blind parallel-group trial of more versus less condensed therapy (2 vs 10 weeks) and d-cycloserine (50 mg) each treatment day versus placebo (in a 2 × 2 design), as potential adjuvants to 60 hours of CIMT. Results. Twenty-four participants entered the study, and 22 completed it and were assessed at the completion of treatment and 3 months later. Neither greater distribution of treatment nor treatment with d-cycloserine significantly augmented retention of gains achieved with CIMT. Conclusions. Greater distribution of practice and treatment with d-cycloserine do not appear to augment retention of gains achieved with CIMT. However, concentration of CIMT over 2 weeks ("massed practice") appears to confer no advantage either. © The Author(s) 2014.

    Triplet antiemetic therapy with neurokinin 1 receptor blocker, 5-hydroxytryptamine receptor blocker and steroids is commonly used in patients who are highly emetic after chemotherapy. However, an alternative antiemetic therapy for patients who are resistant to triplet antiemetic therapy is not established. Olanzapine is recommended in the guidelines as an optional antiemetic drug. However, the effectiveness of adding olanzapine to triplet antiemetic therapy is unknown. In this study, the effectiveness and safety of adding olanzapine to triplet antiemetic therapy with aprepitant, palonosetron and dexamethasone as highly emetic anthracycline-containing adjuvant chemotherapy for primary breast cancer patients were prospectively investigated. Forty-five patients with breast cancer who experienced >Grade 1 nausea or any vomiting after the first cycle of chemotherapy using both epirubicin and cyclophosphamide were included. Low-dose olanzapine (2.5 mg/day) was administered orally from the first day of chemotherapy for 4 days, and the number of episodes of vomiting, scale of nausea, dietary intake and somnolence were compared with the symptoms after the first cycle. As the primary endpoint, the nausea grade was significantly improved by adding olanzapine (P effectiveness and tolerability of adding low-dose olanzapine for patients with insufficient nausea relief with triplet antiemetic therapy consisting of palonosetron, steroid and aprepitant.

    Full Text Available In experimental and clinical research carried out studying of influence of neoadjyuvant photodynamic therapy on T- and B-cellular immune answer in surgical treatment of patients of a melanoma of skin of the I–III stage. PDT was executed to 25 patients two days prior to surgical removal of primary tumor from July, 2012 to January, 2013. As a result of the conducted research it was revealed that: the increase in concentration fotoditaziny doesn‘t lead to increase in quantity of tumoral cages at stages early apoptosis; lengthening of time of an exposition leads to increase in a share of late forms apoptosis, and FDT use with fotoditaziny in a dose of 50,0 mg with the subsequent radiation (662 nanometers, 400 J in 2 days prior to surgical intervention promotes T- and B-cellular link of immune system.

    There is increasing interest in complementary and alternative medicine (CAM) among healthcare professions. However, no studies have been conducted in Sweden or in a surgical context. The aim of this study is to describe different perceptions of complementary therapies among registered healthcare professions in Swedish surgical care. Sixteen interviews were conducted with registered physicians, nurses, physiotherapists and clinical dieticians at a Swedish university hospital. Analysis was made with a phenomenographic research approach. The findings showed variations in perceptions of the definition of complementary therapies. A constructive approach toward use was observed, but there was a conflict in matters of indications and contraindications, and also criticism over a lack of knowledge. There was seen to be a need for education to be able to act professionally. Scepticism over high costs of treatment was highlighted. In conclusion, a need for policies on management, education and research in the field of CAM should be addressed. Copyright © 2010 Elsevier Ltd. All rights reserved.

  20. Adjuvant chemotherapy and cancer cure

    The use of chemotherapy as an adjuvant to surgery and/or radiotherapy is well founded in experimental tumor systems and appears to be effective in patients in some circumstances. It is clear from both clinical and experimental studies that (1) the dose is important, (2) the earlier chemotherapy is started after primary therapy the better, and (3) combination chemotherapy may be more effective than single-agent treatment. The better the estimation of risk of recurrence, the better the assessment of the risk-benefit ratio with adjuvant therapy. Salvage therapy as well as relative risk of recurrence are considerations in the choice of patients to be treated. Finally, some evidence is presented to indicate that alkylating agents may not be necessary in combination regimens for adjuvant therapy if effective antimetabolite combinations are available

    The alterations of deoxyribonuclease DNase activity in cancer cells were the basis of the utilization of mixed vitamins C and K3 in a nontoxic, adjuvant cancer therapy. In order to localize exactly the altered activities of DNase in cancer cells, histochemical methods were utilized. The deficiency of alkaline and acid DNase activity appeared to be characteristic for non-necrotic cells of malignant human and animal tumors. This enzymatic deficiency appeared in experimental carcinogenesis before the phenotypic signs of malignancy. Tumor promoters directly reduced the activity of both DNases. The incidence of spontaneous malignant human and animal tumors appeared to be inversely proportional to the intensity of the activity of both DNases in normal cells and tissues from which these tumors were derived. The fact that alkaline and acid DNase activity was reactivated during the spontaneous and therapeutically induced necrosis of cancer cells suggests that this enzymatic deficiency of DNase activity in cancer cells was due to the action of specific inhibitors of DNases. Characteristic variations of serum alkaline DNase activity in positive responders to therapy, examined in more than 800 cancer-bearing patients, may be the basis for the development of a useful test for therapeutic prognosis and for monitoring of cancer bearing patients. Acid DNase was selectively reactivated in malignant tumor cells by vitamin C (sodium ascorbate), whereas alkaline DNase was reactivated by vitamin K3. Joint vitamin C and K3 administration produced in vitro and in vivo tumor growth inhibition, potentiation and sensitization of chemo- and/or radiotherapy and a decrease in the number of metastases in animals with experimental tumors. Joint vitamin C and K3 administration may be considered as a possible new, non-toxic, adjuvant cancer therapy, which can be easily introduced into the classic protocols of clinical cancer therapy without any supplementary risk for patients.

    Objective: To determine the outcome for patients with recurrent gynecologic tumors treated with radical resection and combined high-dose intraoperative radiation therapy (HDR-IORT). Methods and Materials: Between November 1993 and June 1998, 17 patients with recurrent gynecologic malignancies underwent radical surgical resection and high-dose-rate brachytherapy. The mean age of the study group was 49 years (range 28-72 years). The site of the primary tumor was the cervix in 9 (53%) patients, the uterus in 7 (41%) patients, and the vagina in 1 (6%) patient. The treatment for the primary disease was surgery with or without adjuvant radiation in 14 (82%) patients and definitive radiation in 3 (18%) patients. The current surgery consisted of exenterative surgery in 10 (59%) patients and tumor resection in 7 (41%) patients. Complete gross resection was achieved in 13 (76%) patients. The mean HDR-IORT dose was 14 Gy (range 12-15). Additional radiation in the form of permanent Iodine-125 implant was given to 3 of 4 patients with gross residual disease. The median peripheral dose was 140 Gy. Results: With a median follow-up of 20 months (range 3-65 months), the 3-year actuarial local control (LC) rate was 67%. In patients with complete gross resection, the 3-year LC rate was 83%, compared to 25% in patients with gross residual disease, p<0.01. The 3-year distant metastasis disease-free and overall survival rates were 54% and 54%, respectively. The complications were as follows: gastrointestinal obstruction, 4 (24%); wound complications, 4 (24%); abscesses, 3 (18%); peripheral neuropathy, 3 (18%); rectovaginal fistula, 2 (12%); and ureteral obstruction, 2 (12%). Conclusion: Radical surgical resection and combined IORT for patients with recurrent gynecologic tumors seems to provide a reasonable local-control rate in patients who have failed prior surgery and/or definitive radiation. Patient selection is very important, however, as only those patients with complete gross

    Anti-vascular endothelial growth factor (VEGF) therapy has shown promise in the treatment of high-grade gliomas (HGG). Aflibercept is a recombinant human fusion protein that acts as a soluble decoy receptor for VEGF-A, VEGF-B and placental growth factor, depleting circulating levels of these growth factors. The Adult Brain Tumor Consortium conducted a phase I trial of aflibercept and temozolomide (TMZ) in patients with newly diagnosed HGG with 2 dose levels and a 3+3 design. Three arms using aflibercept were examined; with radiation and concomitant temozolomide; with adjuvant temozolomide using the 5/28 regimen; and with adjuvant temozolomide using the 21/28 day regimen. Fifty-nine patients were enrolled, 21 in arm 1, 20 in arm 2 and 18 in arm 3. Median age was 56 years (24-69); median KPS 90 (60-100). The maximum tolerated dose (MTD) of aflibercept for all 3 arms was 4 mg/kg every 2 weeks. Dose limiting toxicities at the MTD were: Arm 1: 0/21 patients; Arm 2: 2/20 patients (G3 deep vein thrombosis, G4 neutropenia; Arm 3: 3/18 patients) (G4 biopsy-confirmed thrombotic microangiopathy, G3 rash, G4 thrombocytopenia). The median number of cycles of aflibercept was 5 (range, 1-16). All patients stopped treatment; 28 (47%) for disease progression, 21 (36%) for toxicities, 8 (14%) for other reasons, and 2 (3%) patients completed the full treatment course. This study met its primary endpoint and the MTD of aflibercept with radiation and concomitant and adjuvant temozolomide is 4 mg/kg every 2 weeks.

    The indications for and the efficacy of radiation therapy after radical operation for patients with prostate cancer are not clear. We analyzed the treatment results of adjuvant radiotherapy and salvage radiotherapy after radical prostatectomy. Between September 1997 and November 2004, 57 patients received adjuvant radiotherapy or salvage radiotherapy after radical prostatectomy. Fifteen patients received radiation therapy because of positive margins and/or extracapsular invasion in surgical specimens (adjuvant group). Forty-two patients received radiation therapy because of rising prostate-specific antigen (PSA) during follow-up (salvage group). Radiation therapy was delivered to the fossa of the prostate±seminal vesicles by a three-dimensional (3-D) conformal technique to a total dose of 60-66 Gy (median, 60 Gy). Biochemical control was defined as the maintenance of a PSA level of less than 0.2 ng/ml. The median follow-up period after radiation therapy was 33 months (range, 12-98 months). Three-year biochemical control rates were 87% for the adjuvant group and 61% for the salvage group. For patients in the salvage group treated without hormone therapy, the preradiation PSA value was the most significant factor for the biochemical control rate. The 3-year biochemical control rate was 93% in patients whose preradiation PSA was 0.5 ng/ml or less and 29% in patients whose preradiation PSA was more than 0.5 ng/ml. No severe adverse effects (equal to or more than grade 3) were seen in treated patients. Radiation therapy after radical prostatectomy seemed to be effective for adjuvant therapy and for salvage therapy in patients with a preradiation PSA of 0.5 ng/ml or less. Also, radiation to the fossa of the prostate±seminal vesicles, to a total dose of 60-66 Gy, using a three-dimensional (3-D) conformal technique, seemed to be safe. (author)

    Preclinical studies indicate autophagy inhibition with hydroxychloroquine (HCQ) can augment the efficacy of DNA-damaging therapy. The primary objective of this trial was to determine the maximum tolerated dose (MTD) and efficacy of HCQ in combination with radiation therapy (RT) and temozolomide (TMZ) for newly diagnosed glioblastoma (GB). A 3 + 3 phase I trial design followed by a noncomparative phase II study was conducted in GB patients after initial resection. Patients received HCQ (200 to 800 mg oral daily) with RT and concurrent and adjuvant TMZ. Quantitative electron microscopy and immunoblotting were used to assess changes in autophagic vacuoles (AVs) in peripheral blood mononuclear cells (PBMC). Population pharmacokinetic (PK) modeling enabled PK-pharmacodynamic correlations. Sixteen phase I subjects were evaluable for dose-limiting toxicities. At 800 mg HCQ/d, 3/3 subjects experienced Grade 3 and 4 neutropenia and thrombocytopenia, 1 with sepsis. HCQ 600 mg/d was found to be the MTD in this combination. The phase II cohort (n = 76) had a median survival of 15.6 mos with survival rates at 12, 18, and 24 mo of 70%, 36%, and 25%. PK analysis indicated dose-proportional exposure for HCQ. Significant therapy-associated increases in AV and LC3-II were observed in PBMC and correlated with higher HCQ exposure. These data establish that autophagy inhibition is achievable with HCQ, but dose-limiting toxicity prevented escalation to higher doses of HCQ. At HCQ 600 mg/d, autophagy inhibition was not consistently achieved in patients treated with this regimen, and no significant improvement in overall survival was observed. Therefore, a definitive test of the role of autophagy inhibition in the adjuvant setting for glioma patients awaits the development of lower-toxicity compounds that can achieve more consistent inhibition of autophagy than HCQ.

    Vitamin C, as antioxidant, increases the efficacy of deferoxamine (DFO). To investigate the effects of vitamin C as an adjuvant therapy to the three used iron chelators in moderately iron-overloaded young vitamin C-deficient patients with β-thalassemia major (β-TM) in relation to tissue iron overload. This randomized prospective trial that included 180 β-TM vitamin C-deficient patients were equally divided into three groups (n = 60) and received DFO, deferiprone (DFP), and deferasirox (DFX). Patients in each group were further randomized either to receive vitamin C supplementation (100 mg daily) or not (n = 30). All patients received vitamin C (group A) or no vitamin C (group B) were followed up for 1 yr with assessment of transfusion index, hemoglobin, iron profile, liver iron concentration (LIC) and cardiac magnetic resonance imaging (MRI) T2*. Baseline vitamin C was negatively correlated with transfusion index, serum ferritin (SF), and LIC. After vitamin C therapy, transfusion index, serum iron, SF, transferrin saturation (Tsat), and LIC were significantly decreased in group A patients, while hemoglobin and cardiac MRI T2* were elevated compared with baseline levels or those in group B without vitamin C. The same improvement was found among DFO-treated patients post-vitamin C compared with baseline data. DFO-treated patients had the highest hemoglobin with the lowest iron, SF, and Tsat compared with DFP or DFX subgroups. Vitamin C as an adjuvant therapy possibly potentiates the efficacy of DFO more than DFP and DFX in reducing iron burden in the moderately iron-overloaded vitamin C-deficient patients with β-TM, with no adverse events. © 2015 John Wiley & Sons A/S.

    Introduction: Myxopapillary ependymoma (MPE) is a rare tumor in children. The primary treatment is gross total resection (GTR), with no clearly defined role for adjuvant radiation therapy (RT). Published reports, however, suggest that children with MPE present with a more aggressive disease course. The goal of this study was to assess the role of adjuvant RT in pediatric patients with MPE. Methods: Sixteen patients with MPE seen at Johns Hopkins Hospital (JHH) between November 1984 and December 2010 were retrospectively reviewed. Fifteen of the patients were evaluable with a mean age of 16.8 years (range, 12-21 years). Kaplan-Meier curves and descriptive statistics were used for analysis. Results: All patients received surgery as the initial treatment modality. Surgery consisted of either a GTR or a subtotal resection (STR). The median dose of adjuvant RT was 50.4 Gy (range, 45-54 Gy). All patients receiving RT were treated at the involved site. After a median follow-up of 7.2 years (range, 0.75-26.4 years), all patients were alive with stable disease. Local control at 5 and 10 years was 62.5% and 30%, respectively, for surgery alone versus 100% at both time points for surgery and adjuvant RT. Fifty percent of the patients receiving surgery alone had local failure. All patients receiving STR alone had local failure compared to 33% of patients receiving GTR alone. One patient in the surgery and adjuvant RT group developed a distant site of recurrence 1 year from diagnosis. No late toxicity was reported at last follow-up, and neurologic symptoms either improved or remained stable following surgery with or without RT. Conclusions: Adjuvant RT improved local control compared to surgery alone and should be considered after surgical resection in pediatric patients with MPE.

    OBJECTIVE: Historically, patients with esophageal cancer have had a poor outcome despite aggressive treatment approaches. Recently chemo/RT followed by surgical resection has shown a significant improvement in survival in this patient population. The success of this aggressive approach has been predicated on accurate definition of disease extent and appropriate patient selection. We have performed pre-treatment surgical staging (thoracoscopy and laparoscopy) on 38 pts. referred for management of their localized esophageal cancer. The purpose of this report is to compare the results of clinical (CT, MRI, EGD, EUS) vs. surgical staging. The data gathered prospectively will also be used to identify potential predictors for disease-free survival. METHODS: Thirty-eight pts. were treated with combined modality therapy prior to a planned surgical resection. Patients received 50.4 Gy in 1.8 Gy fractions in conjunction with 5 FU (1 Gm/m2) and Cisplatin (100 mg/m2) on days 1 and 28. Patients were evaluated 4 to 6 wks. after completion of therapy for consideration of Ivor-Lewis esophagectomy. Of the original 38 pts., 4 are awaiting surgery, 3 died prior to resection, 2 pts. progressed through chemo/RT, and 1 refused. To date, 28 pts. are available for analysis with a median follow up of 21.5 months. This group included 16 pts. with squamous cell and 12 with adenocarcinoma. RESULTS: Twenty-five of the 28 pts. taken to surgery have undergone pre treatment surgical staging (2 refused, 1 medically unfit). Evaluation of tumor status revealed noninvasive staging to be accurate 56% of the time. Five pts. were converted from T 2 to T 3 , 1 from T 3 to T 4 and 3 T 4 tumors were found to be T 3 . Using the surgical findings at time of staging, 6 pts. were found to have T 2 tumors, 16 had T 3 tumors, and 3 had T 4 tumors. Clinical lymph node status was confirmed in 15 patients (60%). Six went from N+ to N 0 and 4 pts. thought to be N 0 were N+. Eight patients had evidence of positive

    This retrospective study aimed to compare the therapeutic response, including side effects, for oral baclofen versus oral tizanidine therapy with adjuvant botulinum toxin type A in a group of 64 pediatric patients diagnosed with static encephalopathy and spastic equinus foot deformity. Following botulinum toxin A treatment, clinical improvement led to the gradual reduction of baclofen or tizanidine dosing to one-third of the former dose. Gross Motor Functional Measure and Caregiver Health Questionnaire scores were markedly elevated post-botulinum toxin A treatment, with scores for the tizanidine (Gross Motor Functional Measure: 74.45 ± 3.72; Caregiver Health Questionnaire: 72.43 ± 4.29) group significantly higher than for the baclofen group (Gross Motor Functional Measure: 68.23 ± 2.66; Caregiver Health Questionnaire: 67.53 ± 2.67, P botulinum toxin A and a low dose of tizanidine in treating children with cerebral palsy appears to be more effective and has fewer side effects versus baclofen with adjuvant botulinum toxin A. © The Author(s) 2015.

    Lung carcinoma remains an enormous clinical challenge for all health care personnel involved in the care of these patients. Those patients with unresected primary lung carcinoma are ultimately referred for radiation therapy in order to control local regional disease. It is important to recognize the great gains in longevity have not materialized with the addition of adjuvant therapy. However, a very real benefit in the quality of life for most patients with carcinoma of the lung can be achieved with the judicious and thoughtful application of sophisticated radiation therapy, for a small but significant portion of the population, a cure will result from this treatment. This chapter reviews the role of radiation therapy as an adjuvant to definitive surgical treatment

    The 21-gene recurrence score (RS) predicts outcome and benefit from adjuvant chemotherapy benefit in breast cancer patients treated with adjuvant endocrine therapy. In the NSABP B-28 study, we evaluated the 21-gene RS for its prognostic impact and its ability to predict benefit from paclitaxel (P) in node-positive, estrogen receptor-positive (ER+) breast cancer patients treated with adjuvant chemotherapy plus tamoxifen. The B-28 trial compared doxorubicin/cyclophosphamide (AC) with AC followed by P in 3060 patients. Tamoxifen for 5 years was also given to patients > 50 years and those < 50 years with ER+ and/or progesterone receptor-positive (PR+) tumors. The present study includes 1065 ER-positive, tamoxifen-treated patients with RS assessment. Median follow-up time was 11.2 years. In univariate analyses, RS was a significant predictor of outcome. In multivariate analyses, RS remained a significant independent predictor of outcome beyond clinico-pathologic factors, age, and type of surgery (p < 0.001). In the study population (n = 1065), the disease-free survival (DFS) hazard ratio (HR) with adding P to AC was 0.87 (95% CI 0.72-1.05; p = 0.14). RS was not a significant predictor of P benefit: for DFS, HRs for adding P to AC in RS low, intermediate, and high subgroups were 1.01 (95% CI 0.69-1.47; p = 0.99), 0.84 (95% CI 0.62-1.14; p = 0.26), and 0.81 (95% CI 0.60-1.10; p = 0.21), respectively (interaction p = 0.64). Similar findings were observed for the other study endpoints. RS maintains significant prognostic impact in ER-positive, node-positive patients treated with adjuvant chemotherapy plus tamoxifen. However, RS did not significantly predict benefit from adding paclitaxel to AC chemotherapy. (Trial Registration: PDQ: NSABP-B-28).

    Full Text Available IntroductionOrchiopexy for congenital cryptorchid testes is recommended between ½ and 1 year of age to preserve testicular germ cell maturation. Early operation is not enough to preserve fertility in 22 and 36% of cases. Aim of this study was to set up a protocol for optional adjuvant hormonal therapy after orchiopexy and thereafter cryopreservation of testicular biopsies from infants with bilateral cryptorchidism and high infertility risk.Materials and methodsWe included 17 boys with bilateral cryptorchidism, normal FSH, and impaired germ cell number per tubular transverse section (G/T in testicular biopsies at orchiopexy, 7 months to 3½ years old. Postoperatively, optional adjuvant LHRH (kryptocur® 0.2 mg/0.1 mL 2× every second day in 16 weeks were offered. Ten boys were applicable for age matching according to parent’s choice of treatment regime and G/T. Five of them had kryptocur®, and five were controls. Repeat bilateral testicular biopsy evaluation and cryopreservation were offered to all boys 12 months after primary orchiopexy. For cryopreservation, tissue pieces were incubated with a cryoprotectant with a slow program freezing.ResultsTwo out of five kryptorcur®-treated boys normalized both the average G/T and the number of adult dark spermatogonia (Ad-S. Another kryptocur®-treated boy with initial low G/T and no Ad-S increased the G/T and achieved normal number of Ad-S at time of cryopreservation. In the control group, two patients reached only normal lower range regarding the G/T and the number of Ad-S. None of boys with less than average 0.2 G/T improved significantly, whether they were kryptocur®-treated or not.ConclusionBased on literature and the present results, we recommend adjuvant LHRH treatment to boys with cryptorchidism and insufficient genuine gonadotropin stimulation at time of surgery, as these patients have high infertility risk. Cryopreservation should be an option in case of treatment failure

    Objective: To explore the effective therapy for invasive bladder cancer. Methods: Forty patients with invasive bladder cancer were divided into group A and group B. Intra-internal lilac-arterial chemotherapy and infusion pump chemotherapy combined with surgical operation were performed in group A and only surgical operation for group B. The differences of recurrence rates and survival rates between the two groups together with the effectiveness of intra-arterial chemotherapy combined surgical operation were evaluated at the same time. Results: Reduction in volumes of cancer and hematuria were obvious and nearly disappeared in group A patients with pathomorphological features demonstrating large pachyareas of necrosis together with degeneration and inflammatory changes of carcinoma tissue; outcoming with five recurrent cases (20%) and 2 deaths (10%). In group B, 9 cases relapsed(45%) and 4 eases died(20%). Conclusion: The combination of intra-internal lilac-arterial chemoembolization with infusion pump chemotherapy together with surgical operation is safe, effective for invasive bladder cancer, resulting in high raise of survival and life quality.

    Purpose/Objective: Surgical resection offers an opportunity for long term survival for patients with cancer of the pancreas. Unfavorable pathologic prognostic factors following resection of these lesions include positive surgical margins and positive lymph nodes. The purpose of this study was to analyze the influence of IORT on survival of completely resected adenocarcinomas of the pancreas in patients with these poor pathologic features. Materials and Methods: From 1988 to 1994, 391 newly diagnosed patients with carcinoma of the pancreas were seen at Thomas Jefferson University Hospital. Pre-operative work-up identified 166 patients with clinically localized disease. These patients were evaluated by the Department of Radiation Oncology for possible treatment with IORT. These patients underwent exploratory laparotomy and 26 had a complete surgical resection (i.e. Whipple procedure or total pancreatectomy) and received IORT. Mean patient age was 66 ± 2 years (range: 43-80) with 15 male and 11 female patients. All patients had histologically proven adenocarcinoma of the pancreas. IORT was delivered to the surgical tumor bed and regional lymph nodes with a median dose of 15.0 Gy (range: 10.0-20.0 Gy). Technique, field size, and energy of the electron radiation beam varied with the clinical situation and were determined by the radiation oncologist. All 26 patients received post-operative external beam radiation therapy (EBRT) with concurrent weekly 5-FU chemotherapy. Follow-up times ranged from one to 84 months (median: 15 months). Actuarial survival rates were calculated by the Life-Table Method. Patient outcome was evaluated with respect to surgical margin and pathological lymph node status. Results: The overall actuarial 2-year survival rate was 44%. The overall median survival time (MST) was 19 months. At pathological review, five of the 26 patients (19%) were found to have positive surgical margins, four of whom also had involved lymph nodes. Thus, only one

    Many botanical immunomodulators are used as adjuvants along with cancer chemotherapy. However, information on the impact of concurrent administration of such botanicals on pharmacokinetics of chemotherapy agents is inadequate. This study investigates inhibitory activities of 3 popular botanical adjuvants: ASPARAGUS RACEMOSU: (root aqueous extract; ARE), WITHANIA SOMNIFER: (root aqueous extract; WSE), and TINOSPORA CORDIFOLI: (stem aqueous extract, TCE) on human CYP3A4 isoenzyme, responsible for metabolism of several chemotherapy agents. . Testosterone 6-β hydroxylation was monitored using high-performance liquid chromatography as an indicator of CYP3A4 catalytic activities. Ketoconazole (positive control) and extracts were studied at their in vivo-relevant concentrations. TCE showed mild inhibition while no significant inhibitory activities were observed in WSE and ARE. TCE was further fractionated to obtain polar and nonpolar fractions. The nonpolar fraction showed significant CYP3A4 inhibition with IC50 13.06 ± 1.38 µg/mL. Major constituents of nonpolar fraction were identified using HPLC-DAD-MS profiling as berberine, jatrorrhizine, and palmatine, which showed IC50 values as 6.25 ± 0.30, 15.18 ± 1.59, and 15.53 ± 1.89 µg/mL, respectively. Our findings suggest that constituents of TCE extract especially protoberberine alkaloids have the potential to interact with cancer chemotherapy agents that are metabolized by CYP3A4 in vivo.

    A patient with resected stage III nodular melanoma treated with high-dose interferon-alpha-b2 adjuvant therapy went on to develop generalized lymphadenopathy and splenomegaly. The total body positron emission tomography showed a high F-fluorodeoxyglucose uptake (standardized uptake values >9), indicating possible lymph node and spleen malignancies. Histologic examinations of an axillary lymph node biopsy and an osteomedullar biopsy were negative, excluding both melanoma metastases and hematopoietic tumors. The symptoms completely regressed after suspension of treatment and a follow-up positron emission tomography was negative. It remains to be seen whether this unusual event can be ascribed to an autoimmune phenomenon linked to potential treatment efficacy and survival.

    Full Text Available We are witnessing a new era of immune-mediated cancer therapies and vaccine development. As the field of cancer vaccines advances into clinical trials, overcoming low immunogenicity is a limiting step in achieving full success of this therapeutic approach. Recent discoveries in the many biological roles of chemokines in tumor immunology allow their exploitation in enhancing recruitment of antigen presenting cells (APCs and effector cells to appropriate anatomical sites. This knowledge, combined with advances in gene therapy and virology, allows researchers to employ chemokines as potential vaccine adjuvants. This review will focus on recent murine and human studies that use chemokines as therapeutic anti-cancer vaccine adjuvants.

    To test the ability of a reverse transcriptase-PCR (RT-PCR) assay, based on gene expression profiles, to accurately determine the risk of recurrence in patients with node-negative breast cancer who did not receive systemic therapy using formalin-fixed, paraffin-embedded tissue. A secondary objective was to determine whether the quantitative RT-PCR data correlated with immunohistochemistry assay data regarding estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status. We obtained archival paraffin-embedded tissue from patients with invasive breast cancer but no axillary lymph node involvement who had received no adjuvant systemic therapy and been followed for at least 5 years. RNA was extracted from three 10-microm-thick sections. The expression of 16 cancer-related genes and 5 reference genes was quantified using RT-PCR. A gene expression algorithm was used to calculate a recurrence score for each patient. We then assessed the ability of the test to accurately predict distant recurrence-free survival in this population. We identified 149 eligible patients. Median age at diagnosis was 59 years; mean tumor diameter was 2 cm; and 69% of tumors were estrogen receptor positive. Median follow-up was 18 years. The 5-year disease-free survival rate for the group was 80%. The 21 gene-based recurrence score was not predictive of distant disease recurrence. However, a high concordance between RT-PCR and immunohistochemical assays for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status was noted. RT-PCR can be done on paraffin-embedded tissue to validate the large numbers of genes associated with breast cancer recurrence. However, further work needs to be done to develop an assay to identify the likelihood of recurrent disease in patients with node-negative breast cancer who do not receive adjuvant tamoxifen or chemotherapy.

    Full Text Available Aim: The authors evaluate the results of mini-invasive therapy in patients diagnosed with upside-down stomach. Material and methods: From 1998 to 2008, a total of 27 patients diagnosed with upside-down stomach were surgicallytreated at the 1st Department of Surgery, University Hospital Olomouc. Before the operation, patients wereexamined endoscopically and a barium swallow was performed. In all 27 patients (100%, the operation was performedelectively laparoscopically. The principle of the operation in all cases was reposition of the stomach into theabdominal cavity, resection of the hernial sac and hiatoplasty. In addition, in 15 patients (56% with reflux symptomsor endoscopic findings of reflux oesophagitis, fundoplication in Nissen’s modification was also performed. Fundopexywas indicated in 12 patients (44%. Results: In all patients (100%, the operation was performed mini-invasively; conversion to an open procedure wasnever necessary. In 3 cases (11%, the left pleural cavity was opened during the operation; this was treated by introducinga chest drain. The operation mortality in the patient set was zero; morbidity was 11%. A year after the operation,patients were re-examined, and follow-up endoscopy and barium swallow were performed. Conclusions: In all patients diagnosed with upside-down stomach, surgical treatment is indicated due to the risk ofdeveloping severe complications. Mini-invasive surgical therapy in the hands of an experienced surgeon is a safe procedurewhich offers patients all the benefits of mini-invasive therapy with promising short- and long-term results.

    Vocal fold cysts are benign mid-membranous lesions of the true vocal fold, classified as mucus retention or epidermal inclusion cysts. Treatment is surgical excision with or without postoperative voice therapy. A retrospective review was performed of the demographics, treatment approach, and outcomes of patients treated for vocal fold cysts between 2009 and 2014. Voice Handicap Index (VHI)-10 scores before and after treatment were compared using the Wilcoxon Rank-Sum test and the two-tailed Student's t test. Videostroboscopy examinations were reviewed for posttreatment changes in vibratory characteristics of the vocal folds. Twenty-five patients were identified, and one was excluded for incomplete records. Mean age was 41.9 years (66.7% female), and mean follow-up time was 5.58 months. Microflap excision was pursued by 21/24 (87.5%) patients, with 14 patients (58.3%) undergoing perioperative voice therapy. One cyst recurred. Two patients elected for observation, and their cysts persisted. VHI-10 decreased from 23.8 to 6.6 (P Vocal fold cysts impact mucosal wave and glottic closure. Surgical excision resulted in low rates of recurrence, and in improvement in the mucosal wave and VHI-10. Perioperative voice therapy did not offer a significant benefit. Mucus retention cysts were the majority, in contrast to other published studies. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Carcinoma of the endometrium is the most common malignant tumor in the female genital tract. Radiation therapy continues to play a major role in the management of endometrial carcinoma, both as primary therapy and as adjuvant treatment. The utility of pelvic external beam therapy and intracavitary therapy is long established. However, the modern era of surgical staging has lead to an appreciation of the role of radiation therapy beyond the pelvis. Radiation therapy has been shown to be of particular benefit in peritoneal and nodal spread. The classic management of endometrial cancer is reviewed and relatively new and somewhat controversial topics, such as preoperative intracavitary therapy followed by external beam therapy are discussed

    Purpose: Positive surgical margins adversely influence local tumor control in breast conservation therapy (BCT). However, reports have conflicted regarding whether an increased radiation dose can overcome this poor prognostic factor. In this study, we evaluated the influence of an increased radiation dose on tumor control in women with positive surgical margins undergoing BCT. Methods and Materials: Between 1978 and 1994, 733 women with pathologic Stage I-II breast cancer and known surgical margin status were treated at Thomas Jefferson University Hospital with BCT. Of these 733 patients, 641 women had a minimal tumor bed dose of 60 Gy and had documentation of their margin status; 509 had negative surgical margins, and 132 had positive surgical margins before definitive radiotherapy. Complete gross excision of the tumor and axillary lymph node sampling was obtained in all patients. The median radiation dose to the primary site was 65.0 Gy (range 60-76). Of the women with positive margins (n=132), the influence of higher doses of radiotherapy was evaluated. The median follow-up time was 52 months. Results: The local tumor control rate for patients with negative margins at 5 and 10 years was 94% and 88%, respectively, compared with 85% and 67%, respectively, for those women with positive margins (p=0.001). The disease-free survival rate for the negative margin group at 5 and 10 years was 91% and 82%, respectively, compared with 76% and 71%, respectively, for the positive margin group (p = 0.001). The overall survival rate of women with negative margins at 5 and 10 years was 95% and 90%, respectively. By comparison, for women with positive surgical margins, the overall survival rate at 5 and 10 years was 86% and 79%, respectively (p=0.008). A comparison of the positive and negative margin groups revealed that an increased radiation dose (whether entered as a dichotomous or a continuous variable) >65.0 Gy did not improve local tumor control (p=0.776).

    Carbamazepine continues to be the most useful drug in the treatment of trigeminal neuralgia. Diphenylhydantoin may be given in addition to or instead of Carbamazepine. Refractory cases may benefit from combination with Baclofen or Chlorphenesin. In cases of persistent pain the concomitant use of tricyclic antidepressant drugs is recommended. If pain continues in spite of multiple medical therapies or if serious side effects develop, then surgical procedures such as percutaneous controlled thermocoagulation or microvascular decompression are indicated. Percutaneous thermocoagulation is associated with the lowest mortality and morbidity rate and can easily be repeated. Microvascular decompression should especially be offered to young patients, who want to avoid any sensory disturbance of the face, and recommended for other patients for whom all other forms of therapy including percutaneous thermocoagulation have failed.

    In modern surgical oncology, adjuvant therapies are important complementary strategies. In local advanced carcinomas of the gastrointestinal tract, 5-year survival data are still disappointing despite standardized surgery. In this context, it has to be differentiated between adjuvant therapy following complete tumor exstirpation (so-called UICC R{sub 0} resection) and additive therapies following incomplete tumor resections (UICC R{sub 1} or R{sub 2} resection). Modalities in the adjuvant setting are chemotherapy, radiotherapy or the combined radio-/chemotherapy. In esophageal and gastric cancer there is up to now no benefit of postoperative adjuvant therapy. In pancreatic cancer, there are studies indicating a benefit of combined radio-/chemotherapy after complete tumor resection. A standard adjuvant chemotherapeutic treatment is proven in colon cancer stage III (Dukes C) with levamisole and 5-FU. Completely resected rectal carcinoma should be treated postoperatively with combined radio-/chemotherapy. In the common clinical or practical setting, adjuvant therapy is indicated only in locally advanced gastrointestinal tumors following R{sub 0} resection. Postoperative therapy following incomplete tumor resection has its reason only in a palliative intention. (orig.) [Deutsch] Adjuvante Therapiestrategien sind wichtige flankierende Massnahmen der modernen onkologischen Chirurgie, da u.a. die 5-Jahres-Ueberlebensquoten bei lokal fortgeschrittenen Tumoren des Gastrointestinaltraktes nach wie vor unbefriedingend sind.

Als Modalitaeten kommen Chemotherapie, Strahlentherapie und ihre Kombination in Frage. Bei Oesophagus- und Magenkarzinomen kann derzeit keine gueltige Empfehlung zur adjuvanten Therapie gegeben werden. Die Radio

    Reported post-surgery 1-year survival rate for oral canine malignant melanoma (cMM) is around 30%; novel treatments are needed as the role of adjuvant chemotherapy is unclear. This prospective study regards adjuvant electrovaccination with human chondroitin sulfate proteoglycan-4 (hCSPG4)-encoded plasmid in 23 dogs with resected II/III-staged CSPG4-positive oral cMM compared with 19 dogs with resected only II/III-staged CSPG4-positive oral cMM. Vaccination resulted in 6-, 12-, 18- and 24-month survival rate of 95.6, 73.9, 47.8 and 30.4%, respectively [median survival time (MST) 684 days, range 78-1694, 8 of 23 dogs alive] and 6-, 12-, 18- and 24-month disease-free interval (DFI) rate of 82.6, 47.8, 26.1 and 17.4%, respectively (DFI 477 days, range 50-1694). Non-vaccinated dogs showed 6-, 12-, 18- and 24-month survival rate of 63.2, 26.3, 15.8 and 5.3%, respectively (MST 200 days, range 75-1507, 1 of 19 dogs alive) and 6-, 12-, 18- and 24-month DFI rate of 52.6, 26.3, 10.5 and 5.3%, respectively (DFI 180 days, range 38-1250).

    2017-03-01

    There is a lack of clinical research on the potential effect of cannabis use on the periodontium as well as its effect on treatment outcomes. The aim of this case report is to illustrate the clinical presentation of periodontal disease in a young woman who was a chronic cannabis user, as well as successful treatment involving motivating the patient to quit cannabis use and undergo nonsurgical and surgical therapy. A 23-year-old woman sought care at the dental clinic for periodontal treatment. During a review of her medical history, the patient reported using cannabis frequently during a 3-year period, which coincided with the occurrence of gingival inflammation. She used cannabis in the form of cigarettes that were placed at the mandibular anterior region of her mouth for prolonged periods. Localized prominent papillary and marginal gingival enlargement of the anterior mandible were present. The mandibular anterior teeth showed localized severe chronic periodontitis. The clinicians informed the patient about the potentially detrimental consequences of continued cannabis use; she was encouraged to quit, which she did. The clinicians performed nonsurgical therapy (scaling and root planing) and osseous surgery. The treatment outcome was evaluated over 6 months; improved radiographic and clinical results were observed throughout the follow-up period. Substantial availability and usage of cannabis, specifically among young adults, requires dentists to be vigilant about clinical indications of cannabis use and to provide appropriate treatments. Behavioral modification, nonsurgical therapy, and surgical therapy offer the potential for successful management of cannabis-related periodontitis. Copyright © 2017 American Dental Association.

  14. Distinct patterns in the gut microbiota after surgical or medical therapy in obese patients

    Full Text Available Bariatric surgery is highly successful in improving health compared to conventional dietary treatments. It has been suggested that the gut microbiota is a relevant factor in weight loss after bariatric surgery. Considering that bariatric procedures cause different rearrangements of the digestive tract, they probably have different effects on the gut microbiota. In this study, we compared the impact of medical treatment, sleeve gastrectomy and Roux-en-Y gastric bypass on the gut microbiota from obese subjects. Anthropometric and clinical parameters were registered before, 6 and 12 months after treatment. Fecal samples were collected and microbiota composition was studied before and six months post treatment using 16S rRNA gene sequencing and qPCR. In comparison to dietary treatment, changes in intestinal microbiota were more pronounced in patients subjected to surgery, observing a bloom in Proteobacteria. Interestingly, Bacteroidetes abundance was largely different after six months of each surgical procedure. Furthermore, changes in weight and BMI, or glucose metabolism, correlated positively with changes in these two phyla in these surgical procedures. These results indicate that distinct surgical procedures alter the gut microbiota differently, and changes in gut microbiota might contribute to health improvement. This study contributes to our understanding of the impact of weight loss surgery on the gut microbiota, and could be used to replicate this effect using targeted therapies.

    This report addresses the problems related to surgical treatment of post-infarction ventricular tachycardia (VT) and is based on a 5 year experience of 36 consecutive patients. In every case the arrhythmia was unresponsive to pharmacological therapy. All patients were operated on after the completion of a diagnostic protocol including preoperative endocardial, intra-operative epi-endocardial mapping, the latter performed automatically when possible. Surgical techniques were: classical Guiraudon's encircling endocardial ventriculotomy (EEV); partial EEV, endocardial resection (ER); cryoablation or a combination of these procedures. The in-hospital mortality (30 days) was 8.3% (3 patients). During the follow-up period (1-68 months), 3 patients (9%) died of cardiac but not VT related causes. Of the survivors, 92% are VT-free. We consider electrophysiologically guided surgery a safe and reliable method for the treatment of post-infarction VT and suggest its more extensive use. We stress the importance of automatic mapping in pleomorphic and non-sustained VT, and the necessity of tailoring the surgical technique to the characteristics of each case.

    Up to now, the role of adjuvant radiation therapy and the extent of lymph node dissection for early stage endometrial cancer are controversial. In order to clarify the current position of the given adjuvant treatment options, a systematic review was performed. Both, Pubmed and ISI Web of Knowledge database were searched using the following keywords and MESH headings: 'Endometrial cancer', 'Endometrial Neoplasms', 'Endometrial Neoplasms/radiotherapy', 'External beam radiation therapy', 'Brachytherapy' and adequate combinations. Recent data from randomized trials indicate that external beam radiation therapy - particularly in combination with extended lymph node dissection - or radical lymph node dissection increases toxicity without any improvement of overall survival rates. Thus, reduced surgical aggressiveness and limitation of radiotherapy to vaginal-vault-brachytherapy only is sufficient for most cases of early stage endometrial cancer

    Full Text Available Introduction: The risk of postoperative hemorrhage from oral surgical procedures has been a concern in the treatment of patients who are receiving long-term anticoagulation therapy. A study undertaken in our institution to address questions about the amount and severity of bleeding associated with minor outpatient oral surgery procedures by assessing bleeding in patients who did not alter their anticoagulant regimen. Subjects and Methods: Eighty-three patients receiving long-term anticoagulant therapy visited Department of Oral and Maxillofacial Surgery from May 2010 to October 2011 for extractions and minor oral surgical procedures. Each patient was required to undergo preoperative assessment of prothrombin time (PT and measurement of the international normalized ratio. Fifty-six patients with preoperative PT values within the therapeutic range 3-4 were included in the study. The patients′ age ranged between 30 and 75 years. Application of surgispon was done following the procedure. Extraction of teeth performed with minimal trauma to the surrounding tissues, the socket margins sutured, and sutures removed after 5 days. Results: There was no significant incidence of prolonged or excessive hemorrhage and wound infection and the healing process was normal.

    Full Text Available Objective: Survival benefit with adjuvant therapy was shown in patients with Stage III colorectal cancer (CRC. This study evaluates long-term (10-year outcome in patients with CRC randomly assigned to adjuvant 5-Fluorouracil/Leucovorin (5FU+LV or 5-FU/Levamisole (5FU+LEV.Methods: Between 1990 and 1995, 398 patients with curatively resected Stage II-III CRC were randomly assigned to adjuvant 5FU+LV or 5FU+LEV for 12 months.Results: No difference was evident in 10-year relapse-free or overall survival between study groups. Grade III toxicity was similar between groups; however, neurotoxicity was significantly greater with 5FU+LEV (p=0.02 and gastrointestinal toxicity with 5FU+LV (p=0.03. Female patients treated with 5FU+LEV had improved overall survival.Conclusions: Adjuvant treatment of CRC is still based on leucovorin modulated fluorouracil. The long-term follow-up results of this trial indicate that the adjuvant treatment of Stage II-III CRC with 5FU+LV or 5FU+LEV is equally effective. The finding of improved survival in female subjects treated with 5FU+LEV warrants further study to determine if Levamisole is a better modulator of 5-FU than Leucovorin in this patient subset.

    Treatment of gastroesophageal reflux disease in the United States today is binary, with the majority of patients with gastroesophageal reflux disease being treated with antisecre-tory medications and a minority of patients, typically those with volume regurgitation, undergoing Nissen fundoplication. However, there has been increasing dissatisfaction with proton pump inhibitor therapy among a significant number of patients with gastroesophageal reflux disease owing to cost, side effects, and refractory symptoms, and there has been a general reluctance to undergo surgical fundoplication due to its attendant side-effect profile. As a result, a therapy gap exists for many patients with gastroesophageal reflux disease. Alternative techniques are available for these gap patients, including 2 endoscopic fundoplication techniques, an endoscopic radiofrequency energy delivery technique, and 2 minimally invasive surgical procedures. These alternative techniques have been extensively evaluated; however, there are limitations to published studies, including arbitrary definitions of success, variable efficacy measurements, deficient reporting tools, inconsistent study designs, inconsistent lengths of follow-up postintervention, and lack of comparison data across techniques. Although all of the techniques appear to be safe, the endoscopic techniques lack demonstrable reflux control and show variable symptom improvement and variable decreases in proton pump inhibitor use. The surgical techniques are more robust, with evidence for adequate reflux control, symptom improvement, and decreased proton pump inhibitor use; however, these techniques are more difficult to perform and are more intrusive. Additionally, these alternative techniques have only been studied in patients with relatively normal anatomy. The field of gastroesophageal reflux disease treatment is in need of consistent definitions of efficacy, standardized study design and outcome measurements, and improved reporting

    Objective: To discuss the clinical value of interventional management before surgical therapy for massive gastrointestinal hemorrhage, and to compare the clinical efficacy and re-bleeding rate between hypophysin infusion group and embolization group. Methods: During the period of June 1998-Apr. 2009, 31 patients with massive gastrointestinal hemorrhage in our institution underwent preoperative interventional managements before they received surgical treatment. According to DSA manifestations, the patients underwent transarterial hypophysin infusion or transcatheter embolization as interventional management. The clinical efficacy of interventional procedures and its influence on the surgery were evaluated, and the hemostasis rate and re-bleeding rate were compared the two kind of intervention managements. The numeration data were analyzed with Fisher's exact test, and the SPSS 11.0 was used as statistical software. Results: The interventional managements were successfully performed in all the 31 patients, with a total hemostasis rate of 83.9% (26/31) and a total re-bleeding rate 30.7% (8/26). The hemostasis rate and re-bleeding rate of hypophysin infusion group and embolization group were 69.2% (9/ 13), 94.4% (17/18) and 44.4% (4/9), 23.7% (4/17), respectively. All the 31 patients received surgery after interventional therapy, of which selective operation was carried out in 20. Neither surgery-related or intervention-related serious complications nor death occurred. Conclusion: Preoperative interventional managements can provide patients with massive gastrointestinal hemorrhage with valuable chance of a successful surgery, enable the physician to take a selective operation to replace an emergency one,as a result, the surgical risk will be greatly reduced. Therefore, it is worth popularizing the preoperative interventional managements in clinical practice. (authors)

    We studied the anti-arthritic activity of glucomannan (GM) isolated from Candida utilis and of Imunoglukán, a beta-(1,3/1,6)-D-glucan (IMG) isolated from Pleurotus ostreatus. Adjuvant arthritis (AA) was induced intradermally by the injection of Mycobacterium butyricum in incomplete Freund's adjuvant to Lewis rats. Blood for biochemical and immunological analysis was collected on experimental days 1, 14, 21, and 28. A clinical parameter--hind paw volume (HPV)--was also measured. The detection of IL-1 alpha, IL-4, TNF alpha, and MCP-1 was done by immunoflowcytometry. On day 28--the end of the experiment--we determined spectrophotometrically: the total anti-oxidant status (TAS) of plasma samples along with thiobarbituric acid-reacting substances (TBARS) levels in plasma and we assessed the activity of gamma-glutamyl transferase (GGT) in hind paw joint homogenate. The experiments included healthy animals, arthritic animals without treatment, and arthritic animals with administration of glucomannan (GM-AA) in the oral daily dose of 15 mg/kg b.w. and of IMG (IMG-AA) in the oral daily dose of 2 mg/kg b.w. The progress of AA was manifested by all parameters monitored. Both substances had beneficial effects on HPV, TBARS levels, GGT activity, and TAS levels. For cytokine assessment, only IMG-AA samples were selected, considering the significant HPV improvement accompanied with the observed anti-oxidant action. IMG administration had a positive immunomodulating effect on all cytokine plasma levels measured, changed markedly due to arthritis progression. Thus, IMG may be considered as a candidate for combinatorial therapy of rheumatoid arthritis.

    Background: Postoperative radiation therapy for stage I endometrial cancer improves locoregional control but is without survival benefit. To facilitate treatment decision support for individual patients, accurate statistical models to predict locoregional relapse (LRR), distant relapse (DR), overall survival (OS), and disease-free survival (DFS) are required. Methods and Materials: Clinical trial data from the randomized Post Operative Radiation Therapy for Endometrial Cancer (PORTEC-1; N=714 patients) and PORTEC-2 (N=427 patients) trials and registered group (grade 3 and deep invasion, n=99) were pooled for analysis (N=1240). For most patients (86%) pathology review data were available; otherwise original pathology data were used. Trial variables which were clinically relevant and eligible according to data constraints were age, stage, given treatment (pelvic external beam radiation therapy (EBRT), vaginal brachytherapy (VBT), or no adjuvant treatment, FIGO histological grade, depth of invasion, and lymph-vascular invasion (LVSI). Multivariate analyses were based on Cox proportional hazards regression model. Predictors were selected based on a backward elimination scheme. Model results were expressed by the c-index (0.5-1.0; random to perfect prediction). Two validation sets (n=244 and 291 patients) were used. Results: Accuracy of the developed models was good, with training accuracies between 0.71 and 0.78. The nomograms validated well for DR (0.73), DFS (0.69), and OS (0.70), but validation was only fair for LRR (0.59). Ranking of variables as to their predictive power showed that age, tumor grade, and LVSI were highly predictive for all outcomes, and given treatment for LRR and DFS. The nomograms were able to significantly distinguish low- from high-probability patients for these outcomes. Conclusions: The nomograms are internally validated and able to accurately predict long-term outcome for endometrial cancer patients with observation, pelvic EBRT, or VBT

    To evaluate the role of monocular video game play as an adjuvant to occlusion therapy in the treatment of anisometropic amblyopia. In a prospective randomized study design, 68 children with ages ranging from 6 to 14 years who had anisometropic amblyopia with a best corrected visual acuity (BCVA) in the amblyopic eye of better than 6/36 and worse than 6/12 and no manifest strabismus were recruited. They were randomly allocated into two groups: 34 children received 1 hour per day of video game play for the first month plus 6 hours per day of occlusion therapy (video game and occlusion group) and 34 children received 6 hours per day of occlusion therapy alone (occlusion only group). Patients were then evaluated at baseline and 1 and 3 months after treatment for BCVA, stereoacuity, and contrast sensitivity. In the video game and occlusion group, BCVA improved from 0.61 ± 0.12 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.51 ± 0.14 logMAR (P = .001) at 1 month and 0.40 ± 0.15 logMAR (P = .001) at 3 months. In the occlusion only group, BCVA improved from 0.65 ± 0.09 logMAR at baseline to 0.60 ± 0.10 logMAR (P = .001) at 1 month and 0.48 ± 0.10 logMAR (P = .001) at 3 months. There was significantly more improvement in the video game and occlusion group compared to the occlusion only group (P = .003 at 1 month and P = .027 at 3 months). Video game play plus occlusion therapy enhances the visual recovery in anisometropic amblyopia. [J Pediatr Ophthalmol Strabismus. 2017;54(4):244-249.]. Copyright 2017, SLACK Incorporated.

    This study was performed to show long-term outcomes concerning globe preservation in uveal melanoma patients after proton beam therapy with the main focus on outcomes according to different adjuvant ab interno surgical procedures. Retrospective cohort study. All patients treated with primary proton beam therapy for choroidal or ciliary body melanoma between June 1998 and June 2015 were included. A total of 2499 patients underwent primary proton beam therapy, with local tumor control and globe preservation rates of 95.9% and 94.8% after 5 years, respectively. A total of 110 (4.4%) patients required secondary enucleation. Unresponsive neovascular glaucoma was the leading cause of secondary enucleation in 78 of the 2499 patients (3.1%). The 5-year enucleation-free survival rate was 94.8% in the endoresection group, 94.3% in the endodrainage group, and 93.5% in the comparator group. The log-rank test showed P = .014 (comparator group vs endoresection group) and P = .06 (comparator group vs endodrainage-vitrectomy group). Patients treated with endoresection or endodrainage-vitrectomy developed less radiation retinopathy (30.5% and 37.4% after 5 years, P = .001 and P = .048 [Kaplan-Meier], respectively) and less neovascular glaucoma (11.6% and 21.3% after 5 years, P = .001 and P = .01 [Kaplan-Meier], respectively) compared with the comparator group (52.3% radiation retinopathy and 57.8% neovascular glaucoma after 5 years). This study suggests that in larger tumors the enucleation and neovascular glaucoma rates might be reduced by adjuvant surgical procedures. Although endoresection is the most promising adjuvant treatment option, the endodrainage-vitrectomy is recommended in patients who are ineligible for endoresection. Copyright © 2017 Elsevier Inc.

    Objective: To investigate the influence of surgical or propylthiouracil(PTU) pretreatment on the efficacy of radioactive iodine therapy in hyperthyroidism. Methods: A group (group 1) of 41 hyperthyroidism patients relapsed after surgery were treated with 131 I in our department from 2003 through 2004. During that period, another group (group 2) of 41 cases were selected randomly from patients untreated either surgically or chemically before oral administration of 131 I, and a third group (group 3) of 41 cases were selected randomly from those pretreated only with PTU. We analysed the results of these three groups of patients after followed-up for 3 and 6 months separately after 131 I therapy. Results: Approximately 90.24% (37/41 cases) and 92.68% (38/ 41 cases) of patients in group 2 without any pretreatment were cured 3 months and 6 months after 131 I treatment, respectively, and 9.76% (4/41 cases) and 7.32% (3/41 cases) of them did not respond to 131 I treatment. About 43.90% (18/41 cases) and 53.66 % (22/41 cases) of patients pretreated with PTU (group 3) were cured at 3 and 6 months, respectively, and approximately 56.10% (23/41 cases) and 46.34% (19/41 cases) of this group patients did not respond to 131 I treatment at 3 and 6 months, respectively (P 131 I treatment, respectively, and 31.71% (13/41) and 29.27% (12/ 41) of them did not respond to 131 I treatment (P 131 I treatment can affect the efficacy of 131 I therapy, resulting in reduction of the cure rate.

    Purpose: New radiation therapy modalities have broadened treatment options for older women with breast cancer, but it is unclear how clinical factors, geographic region, and physician preference affect the choice of radiation therapy modality. Methods and Materials: We used the Surveillance, Epidemiology, and End Results-Medicare database to identify women diagnosed with stage I-III breast cancer from 1998 to 2007 who underwent breast-conserving surgery. We assessed the temporal trends in, and costs of, the adoption of intensity modulated radiation therapy (IMRT) and brachytherapy. Using hierarchical logistic regression, we evaluated the relationship between the use of these new modalities and patient and regional characteristics. Results: Of 35,060 patients, 69.9% received conventional external beam radiation therapy (EBRT). Although overall radiation therapy use remained constant, the use of IMRT increased from 0.0% to 12.6% from 1998 to 2007, and brachytherapy increased from 0.7% to 9.0%. The statistical variation in brachytherapy use attributable to the radiation oncologist and geographic region was 41.4% and 9.5%, respectively (for IMRT: 23.8% and 22.1%, respectively). Women undergoing treatment at a free-standing radiation facility were significantly more likely to receive IMRT than were women treated at a hospital-based facility (odds ratio for IMRT vs EBRT: 3.89 [95% confidence interval, 2.78-5.45]). No such association was seen for brachytherapy. The median radiation therapy cost per treated patient increased from $5389 in 2001 to $8539 in 2007. Conclusions: IMRT and brachytherapy use increased substantially from 1998 to 2007; overall, radiation therapy costs increased by more than 50%. Radiation oncologists played an important role in treatment choice for both types of radiation therapy, whereas geographic region played a bigger role in the use of IMRT than brachytherapy.

    Definitive therapy is not defined for the management of oral submucous fibrosis (OSMF). This study evaluated the efficacy of aloe vera gel as an adjuvant treatment of OSMF. A double-blind, placebo-controlled, parallel-group randomized controlled trial was conducted on 60 subjects with OSMF divided into medicinal treatment (submucosal injection of hyaluronidase and dexamethasone, n = 30) and surgical treatment (n = 30) categories. Each category was randomly divided into groups A (with aloe vera, n = 15 per category) and B (without aloe vera, n = 15 per category). Follow-up assessment for various symptoms was performed, and results were analyzed using paired and unpaired Student t tests. The group receiving aloe vera had a significant improvement in most symptoms of OSMF (P aloe vera group, in both the medicinal and surgical categories. Aloe vera gel was effective as an adjuvant in treatment of OSMF. Copyright © 2013 Elsevier Inc. All rights reserved.

  10. Radical prostatectomy: positive surgical margins matter.

    2013-10-01

    A positive surgical margin (PSM) in the radical prostatectomy (RP) specimen is associated with biochemical recurrence (BCR) and the need for adjuvant radiation therapy, and is a surrogate for surgical quality. We review the available data describing the identification, anatomy, and management of PSM after RP. A PubMed search (using English language as a filter) was performed to identify factors affecting PSMs and their management. PSMs are associated with an increased likelihood of BCR after RP. The most common location for a PSM is the apex, followed by the posterolateral edge of the prostate. The risk of recurrence in a patient with a PSM is associated with the location, length, and Gleason score of the PSM. The management of a patient with a PSM remains controversial, with some recommending adjuvant radiation therapy for all PSMs and others suggesting only salvage radiation therapy for men who experience BCR. PSMs are associated with an increased likelihood of BCR and often result in initiation of adjuvant treatment. Therefore, the goal of surgery should be to minimize the likelihood of a PSM.

    Purpose/Objective: Since 1992, the University of Maryland has routinely performed preoperative surgical staging including thoracoscopy and laparoscopy on patients undergoing concurrent chemoradiation followed by surgical resection for esophageal carcinoma. We have performed an analysis of the pathologic pretreatment data in an attempt to identify possible predictors of response and outcome. Materials: Patients underwent thoracoscopy and laparoscopy in order to determine resectability of the primary lesion and pathologic nodal status prior to therapy. To date, 32 patients have completed triple modality therapy (28 men, 4 women, median age 59). Patients received 50.4 Gy in 1.8 Gy fractions in conjunction with two cycles of 5-FU (1 gm/m2) and Cisplatin (100 mg/m2) on days 1 and 28. Radiotherapy fields were determined by the extent of disease discovered at time of surgical staging. Ivor Lewis esophagectomy was performed 4 to 6 weeks after completion of chemo/RT. The median follow up is 24.8 months (range 4-49 mo.) Sixteen patients had squamous cell ca and 16 had adenocarcinoma. Univariate and multivariate analysis was performed in order to determine the influence of age, KPS, T stage, Lymph Nodes status and histology, on the likelihood of achieving a pathologic complete response and disease free survival. Results: Twenty-eight have undergone preoperative staging (2 refused, 2 medical contraindications.) All 32 patients are valuable for response to therapy and are included in the analysis. The three year cause specific and disease free survival is 46% and 41% respectively with a median CSS of 23 months and DFS of 19 months. The overall complete response rate assessed by histologic and immunohistologic evaluation at the time of esophagectomy is 31%. The DFS at 32 months is 72% (median not reached) for these patients versus 24% for those with residual disease at the time of surgery. The most significant predictor for the likelihood of achieving a pathologic CR was the

    Patients treated with antithrombotic therapy that require abdominal surgical procedures has progressively increased overtime. The management of antithrombotics during both the peri- and post- operative period is of crucial importance. The goal of this review is to present current data concerning the management of antiplatelets in patients with coronary artery disease and of anticoagulants in patients with atrial fibrillation who had to undergo abdominal surgical operations. For this purpose, incidence of major adverse cardiovascular events (MACE) and risk of antithrombotic use during surgical procedures, as well as the recommendations based on recent guidelines were reported. A thorough search of PubMed, Scopus and the Cochrane Databases was conducted to identify randomized controlled trials, observational studies, novel current reviews, and ESC and ACC/AHA guidelines on the subject. Antithrombotic use in daily clinical practice results to two different pathways: reduction of thromboembolic risk, but a simultaneous increase of bleeding risk. This may cause a therapeutic dilemma during the perioperative period. Nevertheless, careless cessation of antithrombotics can increase MACE and thromboembolic events, however, maintenance of antithrombotic therapy may increase bleeding complications. Studies and current guidelines can assist clinicians in making decisions for the treatment of patients that undergo abdominal surgical operations while on antithrombotic therapy. Aspirin should not be stopped perioperatively in the majority of surgical operations. Determining whether to discontinue the use of anticoagulants before surgery depends on the surgical procedure. In surgical operations with a low risk for bleeding, oral anticoagulants should not be discontinued. Bridging therapy should only be considered in patients with a high risk of thromboembolism. Finally, patients with an intermediate risk for thromboembolism, management should be individualized according to patient

    The effect of flomoxef as empiric therapy for surgical infections of the digestive organs was analyzed in 103 patients, most of whom (94.2%) had intra-abdominal infections. Surgical procedures were performed on 73 patients contemporaneously with the flomoxef therapy. Flomoxef is an oxacephem and has a potent and broad bactericidal spectrum against aerobes and anaerobes. It provokes fewer adverse reactions than latamoxef such as vitamin K deficiency and platelet dysfunction. Flomoxef was administered intravenously at a dose 1-4g/day for more than 3 days without any other antimicrobial agent. The clinical response was classified into 3 groups; cured, improved and failed, and both the cured and improved responses were defined as satisfactory. A satisfactory response was obtained in 99 patients (96.1%). Regarding bacteriological response, the overall eradication rate was 81.3%. Adverse reactions including abnormal laboratory data occurred in only two patients. One had abdominal pain, and the other had a mild elevation of transaminases, and both were mild and easily reversible. Therefore, flomoxef is considered to have the potential of becoming one of the most effective agents in empiric therapy for surgical infections of the digestive organs.

    Chronic periodontitis affects 47% of adult population over the age of 30. The first phase of periodontal treatment is always represented by scaling and root planning (SRP), that is a causal, non-surgical therapy that recognizes as primary aims the control of bacterial infection and the reduction of periodontal plaque-associated inflammation. Yet, another innovative causal therapy is represented by the irradiation of periodontal pockets with laser. To evaluate the effect of a 940-nm diode laser as an adjunct to SRP in patients affected by periodontitis. Sixty-eight adult patients with moderate-to-severe periodontitis were sequentially enrolled and undergone to periodontal examination (V1) in order to detect gingival index (GI), plaque index (PI) and probing depth (PD). The patients were randomly divided into two groups: the first (n=34) received SRP treatment alone, the control group (n=34) received SRP and 940-nm diode laser therapy. Data were analyzed by Student's t-test, with two tails; for all clinical parameters, both groups reported statistically significant differences compared to basal values (pdiode laser was associated with more evident results. Considered the better clinical outcomes, diode laser can be routinely associated with SRP in the treatment of periodontal pockets of patients with moderate-to-severe periodontitis.

    Pediatric thyroid cancer is a rare disease with an excellent prognosis. Compared with adults, epithelial-derived differentiated thyroid cancer (DTC), which includes papillary and follicular thyroid cancer, presents at more advanced stages in children and is associated with higher rates of recurrence. Because of its uncommon occurrence, randomized trials have not been applied to test best-care options in children. Even in adults that have a 10-fold or higher incidence of thyroid cancer than children, few prospective trials have been executed to compare treatment approaches. We recognize that treatment recommendations have changed over the past few decades and will continue to do so. Respecting the aggressiveness of pediatric thyroid cancer, high recurrence rates, and the problems associated with decades of long-term follow-up, a premium should be placed on treatments that minimize risk of recurrence and the adverse effects of treatments and facilitate follow-up. We recommend that total thyroidectomy and central compartment lymph node dissection is the surgical procedure of choice for children with DTC if it can be performed by a high-volume thyroid surgeon. We recommend radioactive iodine therapy for remnant ablation or residual disease for most children with DTC. We recommend long-term follow-up because disease can recur decades after initial diagnosis and therapy. Considering the complexity of DTC management and the potential complications associated with therapy, it is essential that pediatric DTC be managed by physicians with expertise in this area.

    Adjuvant treatment of colon and rectal carcinoma is of major interest. Irradiation and chemotherapy are modalities used widely. The purpose of this study was to evaluate the effect of preoperative irradiation and postoperative intraperitoneal 5-fluorouracil treatment on colonic healing. In rats preoperative irradiation of the lower abdominal region by 10 + 10 Gy four days apart caused inflammatory reaction in the colon as evaluated by histology and determination of myeloperoxidase activity. The inflammatory reaction reached its peek within a week of the second irradiation. When standard used colonic resections and anastomes were performed within the irradiate part of the colon the anastomotic healing was not affected during the first week after operation as judged by complications and breaking strength. A lower breaking strength and an increase in myeloperoxidase activity two months after operation may indicate late changes within the intestinal wall. Intraperitoneal 5-fluorouracil in rat given immediately after colonic resection and repeated as daily injections caused a weight loss and marked reduction in breaking strength of the anastomosis as well as in the abdominal skin wound. A reduction in 5-fluorouracil concentration did not alter the negative wound healing effect of the chemotherapy. In a group of rats subjected to nutritional depletion, mimicking the weight curve of 5-fluorouracil treated animals, anastomotic breaking strength was not compromised to the same extent as when 5-fluorouracil was given. This indicated a direct toxic effect rather than an effect of reduced food intake caused by 5-FU treatment. Collagen synthesis and the formation of new tissue in the wound gap was reduced in 5-fluorouracil treated animals compared to controls as judged by in vivo incorporation of {sup 3}H-proline in the anastomotic segment and determination of anastomotic breaking strength after removal of sutures. 108 refs.

    This study aimed to explore the efficacy of vitamin B complex as an adjuvant therapy for the treatment of complicated vulvovaginal candidiasis (VVC) in vitro and in vivo. One-hundred fifty-eight complicated VVC patients were randomly divided into group A (treated with suppository+oral antifungal agents), group B (treated with suppository+vaginal cream), and group C (treated with suppository+vaginal cream+oral vitamin B complex). A mouse model of VVC was established. Eighty VVC mice were randomly divided into 4 groups according to the dose of vitamin B complex (20 mice in each group): V1 group (injected with 150μL normal salin), V2 group (injected with 50μL vitamin B complex solution+100μL normal saline), V3 group (injected with 100μL vitamin B complex solution+50μL normal saline), and V4 group (injected with 150μL vitamin B complex solution). After 4 weeks of treatment, the vaginal secretion was obtained for microscopic smear examination. HE stainning was performed to observe histopathological changes of vaginal tissues. The expressions of inflammatory factors were detected by ELISA. Meanwhile, VVC model of vaginal epithelial cells was established. The effects of different concentrations of vitamin B complex on anti-fungal effect of fluconazole were detected in vitro. After the treatment, complicated patients in the group C had significantly higher effective rates than those in the group A and group B. After the intra-gastric administration, the microscopic smear examination found that obvious pseudohypha in cluster with a lot of blastospores can be seen in the vaginal secretions of mice in the V1 group under the microscope. There was significant difference between mice treated with different dosages of vitamin B complex. The inflammatory response of mice in the V1 group was significantly higher than those in other groups and the inflammation response reduced with the increase of vitamin B complex dosage. The vitamin B complex elevated the curative effects of

    Overexpression of the androgen receptor (AR) splice variant 7 (AR-V7) has recently been reported to be associated with resistance to antihormonal therapy. Herein, we address the question whether tumor cells with AR-V7 expression can be detected at the time of radical prostatectomy, that is, before long-term hormonal manipulation and castration resistance, and what the potential prognostic impact on the biochemical recurrence (BCR)-free survival may be. An anti-AR-V7 antibody was first validated in a training set of prostate cancer specimens by a comparison of AR-V7 protein to AR-V7 mRNA expression. We then analyzed nuclear AR-V7 protein expression in the primary tumors and lymph node metastases from 163 predominantly high-risk patients (cohort I) as well as the primary tumors from patients of a second, consecutive patient cohort (n = 238, cohort II) not selected for any clinicopathological features. Staining results were correlated to patient characteristics and BCR-free patient survival. High nuclear AR-V7 protein expression was detected in approximately 30%-40% of patients in cohort I and II at the time of radical prostatectomy. High baseline expression of nuclear AR-V7 protein was associated with an unfavorable BCR-free survival in the high-risk patient cohort I but not in the unselected consecutive cohort II. Remarkably, AR-V7 was an independent negative prognostic factor in high-risk prostate cancer patients of cohort I who were selected to receive adjuvant treatment. Prostate cancer cells with high nuclear AR-V7 protein expression can be detected in a substantial proportion of tumors at the time of radical prostatectomy. The presence of AR-V7-positive tumor cells is associated with an unfavorable prognosis for BCR-free survival in a high-risk patient cohort including a subgroup of patients selected to receive adjuvant therapy, in which AR-V7 was an independent negative prognosticator. Overexpression of nuclear AR-V7 protein hence identifies a subset of tumors

    There is a decided lack of in-depth studies to evaluate the effectiveness of Chinese Herbal Medicine (CHM) as an adjuvant therapy on the incidence of chronic hepatitis in patients with colon cancer. The aim of this study is to assess whether CHM treatment decreased the incidence of chronic hepatitis in colon cancer patients who received conventional Western medical treatment. A Taiwanese nationwide population-based study of colon cancer patients receiving Western medicine treatment in conjunction with CHM treatment, using data provided by the National Health Insurance (NHI) Research Database, was conducted. A total of 61676 patients were diagnosed with colon cancer in Taiwan within the defined study period, from 1997 to 2010. After randomly equal matching for age, sex, excluding patients younger than 18 years of age, chronic hepatitis before colon cancer diagnosis date, receiving acupuncture and/or moxibustion and taking CHM for less than 30 days, data from 155 patients were analyzed. Hazard ratios of incidence rate of chronic hepatitis were used to determine the influence of CHM and the therapeutic potential of herbal products in treating patients with colon cancer. CHM used for patients with colon cancer exhibited significantly decreased incidence rates of chronic hepatitis [hazard ratio (HR)=0.53; 95% confidence interval (CI):0.38-0.74], with multivariate adjustment, compared to those without CHM use. The protective effect of CHM treatment with statistical significance across the stratification of age, gender, co-morbidity and treatment modality was noted. The cumulative incidence of chronic hepatitis was also reduced in patients with colon cancer receiving CHM treatment during a five-year period. In this study, we provide the ten most used single herbs and herbal formulas that were prescribed for patients with colon cancer; moreover, we identify the eight single herbs and five formulas used in CHM treatment which significantly decreased incidence of chronic

    Radiation therapy (RT) comprises a key component in the treatment of breast cancer. Radiation-induced skin toxicity is the major adverse event experienced by patients; however, radiodermatitis (RD) prevention and management remains trivial. It is proven that photobiomodulation (PBM) therapy using light-emitting diode (LED) increases wound healing and depicts an anti-inflammatory effect. This single-institute study evaluates the beneficial role of PBM-LED in preventing/reducing RD during breast cancer RT. Of 70 consecutively treated patients, 25 patients were treated with PBM-LED twice a week prior to adjuvant 3D conformal RT after breast-conserving surgery. RD was reported using Common Toxicity Criteria for Adverse Events Version 4.0 and pain intensity using a visual analog scale (VAS). For comparison, a control group (n = 45) received RT without PBM-LED. In addition, a ''matched'' group (n = 25) was generated from the control group based on propensity for potentially confounding variables. In the PBM group, 22 patients (88%) presented grade 1 and 3 (12%) grade 2 RD. In the control group, 25 patients (55.6%) developed grade 1 reactions, 18 patients (40%) grade 2, and 2 (4.4%) patients grade 3 RD. Concerning pain intensity, 15 patients (60%) of the PBM treatment arm reported no pain, 5 patients (20%) VAS 2, and 5 (20%) VAS 3. In the control group, 13 patients (28.9%) reported no pain, 2 (4.4%) VAS 1, 7 (15.6%) VAS 2, 9 patients (20%) reported VAS 3, 12 (26.7%) patients VAS 4, and 2 (4.4%) patients VAS 5. PBM-LED therapy applied prior to RT might be effective in decreasing the incidence and sequelae of radiation-induced skin toxicity in breast cancer patients treated with breast-conserving surgery.

    The aim of this study was to investigate the extent of discontinuation of oral adjuvant endocrine therapy (OAET) in women nearly 4 years from the diagnosis of their first episode of invasive breast cancer and the reasons for such discontinuation. We used a large, prospective cohort study of women who had been diagnosed with their first episode of invasive breast cancer between 2004 and 2006, recruited through a state-based cancer registry. All participants completed an enrollment questionnaire (EQ) within 12 months of diagnosis and annual follow-up questionnaires (FQs) thereafter. The data in this report were obtained from the EQ and the first three FQs. A total of 1,370 women with hormone receptor-positive disease completed the EQ. At the completion of the third FQ nearly 4 years from diagnosis, 1,193 women remained in the study. Use of OAET peaked by 2 years postdiagnosis. At nearly 4 years from diagnosis, 18% of the 1,193 women remaining in the study were not taking OAET. Of these women, just more than half had ceased therapy mainly owing to a range of adverse effects, predominantly estrogen deficiency symptoms, but the remainder (8% of women remaining in the study) had never used OAET. Our study confirms that early discontinuation of OAET due to estrogen deficiency symptoms remains an important issue despite calls for strategies to address this problem. The number of women potentially suitable for OAET but not receiving it was almost as great as the number of those who have discontinued therapy.

    Several prospective studies into the effects of adjuvant systemic therapy on cognitive functioning suggest that a proportion of breast cancer patients show cognitive deficits already before the start of systemic therapy. Owing to, among others, methodological inconsistency, studies report different rates of this pre-treatment cognitive impairment. We examined the impact of four different criteria of cognitive impairment and two types of reference groups (a study-specific healthy reference group versus published normative data) on the prevalence of cognitive impairment. Two hundred and five postmenopausal breast cancer patients underwent a battery of neuropsychological tests before the start of endocrine therapy, 124 healthy subjects underwent the same tests. Proportions of cognitive impaired patients were calculated for each of four criteria for cognitive impairment, using (1) study-specific healthy controls and (2) published norms of healthy controls as reference groups. The prevalence of cognitive impairment varied greatly with the strictness of the criterion, as expected, but also was dependent on the reference group used. Cognitive impairment, relative to published norms, ranged from 1% for the strictest to 36.6% for the less strict criterion, cognitive impairment relative to study-specific healthy controls, ranged from 13.7 to 45.4% for the same criteria. This study highlights contrasting proportions of cognitive impairment by using different criteria for cognitive impairment and different reference groups. (Dis)advantages of the methods using a criterion for cognitive impairment, and of the use of published norms versus a study-specific reference group are discussed.

    Compliance of physicians with guidelines has emerged as an important indicator for quality of care. We evaluated compliance of physicians with adjuvant therapy guidelines for endometrial cancer patients in the Netherlands in a population-based cohort over a period of 10years. Data from all patients diagnosed with endometrial cancer between 2005 and 2014, without residual tumor after surgical treatment, were extracted from the Netherlands Cancer Registry (N=14,564). FIGO stage, grade, tumor type and age were used to stratify patients into risk groups. Possible changes in compliance over time and impact of compliance on survival were assessed. Patients were stratified into low/low-intermediate (52%), high-intermediate (21%) and high (20%) risk groups. Overall compliance with adjuvant therapy guidelines was 85%. Compliance was highest in patients with low/low-intermediate risk (98%, no adjuvant therapy indicated). The lowest compliance was determined in patients with high risk (61%, external beam radiotherapy with/without chemotherapy indicated). Within this group compliance decreased from 64% in 2005-2009 to 57% in 2010-2014. In high risk patients with FIGO stage III serous disease compliance was 55% (chemotherapy with/without radiotherapy indicated) and increased from 41% in 2005-2009 to 66% in 2010-2014. While compliance of physicians with adjuvant therapy guidelines is excellent in patients with low and low-intermediate risk, there is room for improvement in high risk endometrial cancer patients. Eagerly awaited results of ongoing randomized clinical trials may provide more definitive guidance regarding adjuvant therapy for high risk endometrial cancer patients. Copyright © 2017 Elsevier Inc.

    The authors report preliminary findings of the investigation of the effect of combination photon-magnetic therapy with successive application of red and blue light to the skin of breast cancer patients during the course of post-operative radiation therapy. It was established that photonmagnetic therapy positively influenced the state of the skin in the irradiated areas. Addition of the magnetic factor significantly improved the efficacy of phototherapy. The patients receiving photon-magnetic therapy finished the course of radiation therapy with almost unchanged skin.

    Purpose: To establish the toxicity profile of simultaneously administered postoperative radiation therapy and CMF chemotherapy as a prelude to a randomized controlled study addressing the sequencing of the two modalities. Methods and Materials: One hundred and thirty eight breast cancer patients at high risk of locoregional, as well as systemic relapse, who were referred to three centers in Australia and New Zealand were treated with postoperative radiation therapy and chemotherapy simultaneously. Acute toxicity and dose modifications in these patients were compared with 83 patients treated over the same time frame with chemotherapy alone. In a separate study the long-term radiation and surgical effects in 24 patients treated simultaneously with radiation therapy and chemotherapy at Newcastle (Australia) following conservative surgery were compared with 23 matched patients treated at Newcastle with radiation therapy alone. Results: Myelotoxicity was increased in patients treated simultaneously with radiation therapy and chemotherapy. The effect was not great, but may have contributed to chemotherapy dose reductions. Lymphopenia was observed to be the largest factor in total white cell depressions caused by the simultaneous administration of radiation therapy. Postsurgical appearances were found to so dominate long-term treatment effects on the treated breast that the effect of radiation therapy dose and additional chemotherapy was difficult to detect. Conclusion: Studies addressing the sequencing of radiation therapy and chemotherapy will necessarily be large because adverse effects from administering the two modalities simultaneously are not great. The present study has endorsed the importance in future studies of stratification according to the extent and type of surgery and adherence to a single strict policy of chemotherapy dose modification

    Full Text Available Patients with haemophilia type A or B may develop, over time, haemophilic arthropathy with different degrees of joint dysfunction. This disorder is a consequence of repeated episodes of intraarticular bleeding, with either spontaneous or traumatic aetiology. In the recent years, the therapeutic management of these patients has changed, still, without prompt early diagnosis and prophylactic treatment, the joints deteriorate to such a degree that only a complex multi-disciplinary approach can offer an optimal outcome. Modern high resolution MRI and prophylaxis treatment can detect and delay early signs of haemophilic arthropathy, but, not all patients have access to these types of early interventions. As a result, there are still patients presenting with different of degrees haemophilic arthropathy, which require surgical treatment. Despite the use of modern, minimal invasive approaches, surgical treatment alone can’t offer a good symptom relief and can’t provide a good functional outcome. Thus, the integration of physical therapy and functional rehabilitation in the therapeutic scheme can provide a good support in order for these patients to be socio-economically re-integrated.

    Unfavourable hemodynamics in heart failure patients implanted with left ventricular assist devices (LVAD), due to non-optimal surgical configurations and patient management, strongly influence thrombogenicity. This is consistent with the increase in devastating thromboembolic complications (specifically thrombosis and stroke) in patients, even as the risk of thrombosis inside the device decreases with modern designs. Inflow cannula and outflow graft surgical configurations have been optimized via patient-specific modeling that computes the thrombogenic potential with a combination of Eulerian (endothelial) wall shear stress and Lagrangian (platelet shear history) tracking. Using this view of hemodynamics, the benefits of intermittent aortic valve opening (promoting washout and reducing stagnant flow in the aortic valve region) have been assessed in managing the patient's residual native cardiac output. The use of this methodology to understand the contribution of the hemodynamics in the flow surrounding the LVAD itself to thrombogenesis show promise in developing holistic patient-specific management strategies to minimize stroke risk and enhance efficacy of LVAD therapy.

    Purpose: The purpose of this report is to describe trends in primary surgical and radiation therapy for localized breast cancer from 1973 through 1992 among residents of the Detroit Metropolitan area. Methods and Materials: Data on surgical and radiation therapy procedures for women with local stage breast cancer were obtained from the population-based Metropolitan Detroit Cancer Surveillance System (MDCSS). Results: Women age 75 years and older were treated less aggressively than younger women (< age 75) as evidenced by higher rates of simple mastectomy or no treatment among older women. Younger women (< age 75) were more likely to have had optimal breast conservation therapy which consisted of partial mastectomy, axillary lymph node dissection (ALND), and radiation therapy, than were women who were older than 75. Partial mastectomy has increased proportionally from 4% of all breast cancer surgeries in the time period 1973 to 1977, to 39% of all surgeries from 1988 through 1992. Conclusion: A marked difference in surgical treatment of breast cancer exists for younger vs. older women. Despite changes in surgical treatment trends for breast cancer, a large proportion of women who are candidates for conservative therapy continue to undergo mastectomy

    Background: Limb soft tissue sarcomas (STS) are currently treated with limb sparing surgery (LSS) followed by radiation therapy (RT). Patients and methods: Between October 1994 and October 2002, 133 adult patients with intermediate or high-grade limb STS were approached by LSS+RT. Results: RT related toxicity was manageable, with a low rate of severe effects. At 4-year median follow-up, there were 48 recurrences of any type, 23 of isolated local failure, and 35 of systemic spread w/o local failure. DFS and OS were influenced by disease stage II vs I, primary site in the upper limb vs lower limb, MPNST vs other types, induction therapy vs no induction, adequate resection vs marginal resection or involved margins, and good response to induction therapy vs bad response. DFS and OS were Patient's age and sex, tumor depth, acute or late toxicity of RT, or the interval of time between the date of definitive surgery and the start of RT did not affect DFS and or OS. Conclusions: The RT protocol is applicable in the era of complicated, expensive and time-consuming 3D therapy. Our results of LSS+RT in adults with limb HG STS are satisfactory

    To evaluate the effects of reflexology treatment on quality of life, sleep disturbances, and fatigue in breast cancer patients during radiation therapy. A total of 72 women with breast cancer (stages 1-3) scheduled for radiation therapy were recruited. Women were allocated upon their preference either to the group receiving reflexology treatments once a week concurrently with radiotherapy and continued for 10 weeks or to the control group (usual care). The Lee Fatigue Scale, General Sleep Disturbance Scale, and Multidimensional Quality of Life Scale Cancer were completed by each patient in both arms at the beginning of the radiation treatment, after 5 weeks, and after 10 weeks of reflexology treatment. The final analysis included 58 women. The reflexology treated group demonstrated statistically significant lower levels of fatigue after 5 weeks of radiation therapy (p fatigue, quality of sleep, pain, and quality of life in breast cancer patients during radiation therapy. Reflexology prevented the decline in quality of life and significantly ameliorated the fatigue and quality of sleep of these patients. An encouraging trend was also noted in amelioration of pain levels.

    In this study 35 breast cancer patients were followed during their treatment in Radiation and Isotope Center of Khartoum (RICK) using breast cancer antigen CA 15-3 as an indicator of tumor marker. They were classified into three categories of CA 15-3 concentration level as stated by Colomer and Genolla (1989) as follows: normal level less than 40 UI/ml, moderate level more than 40 UI/ml and less than 60 UI/ml, and high level, more than 60 UI/ml to 3000 UI/ml. A 5 ml of venous blood samples' were collected using sterile syringes from patients with different stage of breast cancer. The sample size were thirty-five cases, one of the cases is rejected because the patient discontinued the treatment. The blood samples were collected as follows: before starting the treatment course, at the mid time of treatment course, after completion the treatment course, and after one month of completion of the treatment course. The patients classified into two groups according to their treatment protocol. The first group received only external radiation therapy treatment and those were 18 patients out of 35, while the second group received combined therapy and those were 16 patients out of 35. For those whom received external radiation radiation therapy only, the results showed that the mean value of CA 15-3 concentration level decreased at the mid of the treatment as follows: 26±3 UI/ml, 24±3 UI/ml, 22±3 UI/ml respectively, while the mean value of CA 15-3 concentration level before starting the treatment was found to be 46±14 UI/ml. The number of the patients in the normal concentration level of CA 15-3 increased by 11% at the mid of external radiotherapy treatment and by 13% at the mid combined therapy, while the moderate level decreased by 6% for both external radiotherapy and combined therapy, while the number of patients within the high level decreased by 5% for external radiotherapy and 7% for combined therapy. After completion and after one month of completion of external

    Background: A joint analysis of data from centers involved in the Spanish Cooperative Initiative for Intraoperative Electron Radiotherapy was performed to investigate long-term outcomes of locally recurrent soft tissue sarcoma (LR-STS) patients treated with a multidisciplinary approach. Methods and Materials: Patients with a histologic diagnosis of LR-STS (extremity, 43%; trunk wall, 24%; retroperitoneum, 33%) and no distant metastases who underwent radical surgery and intraoperative electron radiation therapy (IOERT; median dose, 12.5 Gy) were considered eligible for participation in this study. In addition, 62% received external beam radiation therapy (EBRT; median dose, 50 Gy). Results: From 1986 to 2012, a total of 103 patients from 3 Spanish expert IOERT institutions were analyzed. With a median follow-up of 57 months (range, 2-311 months), 5-year local control (LC) was 60%. The 5-year IORT in-field control, disease-free survival (DFS), and overall survival were 73%, 43%, and 52%, respectively. In the multivariate analysis, no EBRT to treat the LR-STS (P=.02) and microscopically involved margin resection status (P=.04) retained significance in relation to LC. With regard to IORT in-field control, only not delivering EBRT to the LR-STS retained significance in the multivariate analysis (P=.03). Conclusion: This joint analysis revealed that surgical margin and EBRT affect LC but that, given the high risk of distant metastases, DFS remains modest. Intensified local treatment needs to be further tested in the context of more efficient concurrent, neoadjuvant, and adjuvant systemic therapy.

    Purpose: We used the Female Sexual Function Index (FSFI) to investigate the prevalence of sexual dysfunction (SD) and factors associated with diminished sexual functioning in early stage endometrial cancer (EC) patients treated with simple hysterectomy and adjuvant brachytherapy. Methods and Materials: A cohort of 104 patients followed in a radiation oncology clinic completed questionnaires to quantify current levels of sexual functioning. The time interval between hysterectomy and questionnaire completion ranged from <6 months to >5 years. Multivariate regression was performed using the FSFI as a continuous variable (score range, 1.2-35.4). SD was defined as an FSFI score of <26, based on the published validation study. Results: SD was reported by 81% of respondents. The mean ({+-} standard deviation) domain scores in order of highest-to-lowest functioning were: satisfaction, 2.9 ({+-}2.0); orgasm, 2.5 ({+-}2.4); desire, 2.4 ({+-}1.3); arousal, 2.2 ({+-}2.0); dryness, 2.1 ({+-}2.1); and pain, 1.9 ({+-}2.3). Compared to the index population in which the FSFI cut-score was validated (healthy women ages 18-74), all scores were low. Compared to published scores of a postmenopausal population, scores were not statistically different. Multivariate analysis isolated factors associated with lower FSFI scores, including having laparotomy as opposed to minimally invasive surgery (effect size, -7.1 points; 95% CI, -11.2 to -3.1; P<.001), lack of vaginal lubricant use (effect size, -4.4 points; 95% CI, -8.7 to -0.2, P=.040), and short time interval (<6 months) from hysterectomy to questionnaire completion (effect size, -4.6 points; 95% CI, -9.3-0.2; P=.059). Conclusions: The rate of SD, as defined by an FSFI score <26, was prevalent. The postmenopausal status of EC patients alone is a known risk factor for SD. Additional factors associated with poor sexual functioning following treatment for EC included receipt of laparotomy and lack of vaginal lubricant use.

    We evaluated associations between personal and clinical social support and non-adherence to adjuvant endocrine therapy (AET) in a large, Northern California breast cancer (BC) cohort from an integrated healthcare network. This study included 3382 women from the Pathways Study diagnosed from 2005 to 2013 with stages I-III hormone receptor-positive BC and who responded to the Medical Outcomes Study Social Support and Interpersonal Processes of Care surveys, approximately 2 months post-diagnosis. We used logistic regression to evaluate associations between tertiles of social support and non-initiation (social support (P trend = 0.02). Women with moderate (HR 1.20, 95% CI 0.99-1.45) or low (HR 1.32, 95% CI 1.09-1.60) personal social support were also more likely to discontinue treatment (P trend = 0.01). Furthermore, women with moderate (HR 1.25, 95% CI 1.02-1.53) or low (HR 1.38, 95% CI 1.12-1.70) personal social support had higher non-adherence (P trend = 0.007). Associations with clinical social support and outcomes were similar. Notably, high clinical social support mitigated the risk of discontinuation when patients' personal support was moderate or low (P value = 0.04). Women with low personal or clinical social support had higher AET non-adherence. Clinician teams may need to fill support gaps that compromise treatment adherence.

    From March 1970 to December 1984, treatment results of 21 patients treated initially with curative surgery for adenocarcinoma of the colon and referred to the Department of Radiation Oncology, College of Medicine, Yonsei University, were analyzed retrospectively. Thirteen of 21 patients who were considered to be at high risk (i.e, stage B2 or above), received postoperative adjuvant radiation therapy. However, 2 of 13 patients did not complete their courses of radiotherapy as planned because of poor tolerance to radiotherapy or patient refusal and were excluded from this study. Remaining 8 of 21 patients who did not receive postoperative radiotherapy, presented with recurrence at the time of referral and treated for palliation. In 11 patients who finished postoperativc radiotherapy, overall local failure rate was 9%(1/11) and the 5 year actuarial survival rate was 55%. Local failure rates by stage were 0(0/4), 14%(1/7) for stage B2+B3, C1+C2+C3 respectively and 0(0/2), 17%(1/6), 0(0/3) for stage C1, B2+C2, B3+C3 respectively

    Melatonin's therapeutic potential is grossly underestimated because its functional roles are diverse and its mechanism(s) of action are complex and varied. Melatonin produces cellular effects via a variety of mechanisms in a receptor independent and dependent manner. In addition, melatonin is a chronobiotic agent secreted from the pineal gland during the hours of darkness. This diurnal release of melatonin impacts the sensitivity of melatonin receptors throughout a 24-hr period. This changing sensitivity probably contributes to the narrow therapeutic window for use of melatonin in treating sleep disorders, that is, at the light-to-dark (dusk) or dark-to-light (dawn) transition states. In addition to the cyclic changes in melatonin receptors, many genes cycle over the 24-hr period, independent or dependent upon the light/dark cycle. Interestingly, many of these genes support a role for melatonin in modulating metabolic and cardiovascular physiology as well as bone metabolism and immune function and detoxification of chemical agents and cancer reduction. Melatonin also enhances the actions of a variety of drugs or hormones; however, the role of melatonin receptors in modulating these processes is not known. The goal of this review is to summarize the evidence related to the utility of melatonin as a therapeutic agent by focusing on its other potential uses besides sleep disorders. In particular, its use in cancer prevention, osteoporosis and, as an adjuvant to other therapies are discussed. Also, the role that melatonin and, particularly, its receptors play in these processes are highlighted.

    Full Text Available Adjuvant endocrine therapy (AET taken for a minimum of five years reduces the recurrence and mortality risks among women with hormone-sensitive breast cancer. However, adherence to AET is suboptimal. To guide the development of theory-based interventions to enhance AET adherence, we conducted a study to explore beliefs regarding early adherence to AET. This qualitative study was guided by the Theory of Planned Behavior (TPB. We conducted focus groups and individual interviews among women prescribed AET in the last two years (n = 43. The topic guide explored attitudinal (perceived advantages and disadvantages, normative (perception of approval or disapproval, and control beliefs (barriers and facilitating factors towards adhering to AET. Thematic analysis was conducted. Most women had a positive attitude towards AET regardless of their medication-taking behavior. The principal perceived advantage was protection against a recurrence while the principal inconvenience was side effects. Almost everyone approved of the woman taking her medication. The women mentioned facilitating factors to encourage medication-taking behaviors and cope with side effects. For adherent women, having trouble establishing a routine was their main barrier to taking medication. For non-adherent women, it was side effects affecting their quality of life. These findings could inform the development of community pharmacy-based adherence interventions.

    To examine clinical and demographic characteristics of a population-based cohort of patients with uterine carcinosarcoma (UCS), to assess access to treatment and survival patterns. Surveillance, Epidemiology and End Results database was queried for patients diagnosed in 1999-2010 and treated with surgery with or without adjuvant radiation therapy (aRT). The Kaplan-Meier method was used to estimate survival functions, and Cox proportional hazards regression - to analyze the effect of covariates on survival. 2342 patients were eligible. African Americans presented with more advanced AJCC stages than other races (35.4% vs. 29.1%; pAfrican Americans vs. others, and women diagnosed in 1999-2004 vs. in 2005-2010, received aRT at a similar rate: 36.5% vs. 39.9% (p=NS), and 39.5% vs. 38.9% (p=NS), respectively. There was a trend towards higher aRT utilization among patients younger than 65 vs. older (41.4% vs. 37.5%; paRT group: 42 vs. 22 (paRT group. African Americans were more likely to present with later stage disease and die of UCS than non-African Americans. Age and stage, but not race, influenced receipt of aRT.

    The objective of this study was to estimate the risk of a cardiovascular event or death associated with modern radiation in a population of elderly female breast cancer patients with varying baseline cardiovascular risk. The data used for this analysis are from the linked Surveillance, Epidemiology, and End-Results (SEER)-Medicare database. The retrospective cohort study included women aged 66 years and older with stage 0–III breast cancer diagnosed between 2000 and 2005. Women were grouped as low, intermediate, or high cardiovascular risk based on the presence of certain clinical diagnoses. The risk for the combined outcome of a hospitalization for a cardiovascular event or death within 6 months and 24 months of diagnosis was estimated using a multivariable Cox model. The median follow-up time was 24 months. Among the 91,612 women with American Joint Committee on Cancer (AJCC) stage 0–III breast cancer: 39,555 (43.2%) were treated with radiation therapy and 52,057 (56.8%) were not. The receipt of radiation therapy in the first 6 months was associated with a statistically significant increased risk for the combined outcome in women categorized as high risk (HR = 1.510; 95% CI, 1.396–1.634) or intermediate risk (HR = 1.415; 95% CI, 1.188–1.686) but not low risk (HR = 1.027; 95% CI, 0.798–1.321). Women with a prior medical history of cardiovascular disease treated with radiation therapy are at increased risk for an event and should be monitored for at least 6 months following treatment with radiation therapy

    Full Text Available Abstract Introduction Cutaneous eccrine porocarcinomas are uncommon malignant tumors of the sweat gland. Case Presentation A 76-year-old Caucasian man presented to our hospital with a left temporal mass. We describe a case of eccrine porocarcinoma with metastasis to the parotid gland with special emphasis on the role of surgical resection and adjuvant radiation therapy. Conclusion Besides surgical resection, little is known about the role of adjuvant therapy in managing eccrine porocarcinomas. Radiation therapy should be considered within a multidisciplinary approach in patients with primary or recurrent eccrine porocarcinomas.

    Background and purpose: In men with adverse pathology at the time of radical prostatectomy (RP), the most appropriate timing to administer radiotherapy (RT) remains a subject for debate. To determine whether salvage radiotherapy (SRT) upon early prostate-specific antigen (PSA) relapse is equivalent to immediate adjuvant radiotherapy (ART) post RP. Material and methods: 130 patients receiving ART and 89 receiving SRT were identified. All had an undetectable PSA after RP. Homogeneous subgroups were built based on the status (±) of lymphatic invasion (LVI) and surgical margins (SM), to allow a comparison of ART and SRT. Biochemical disease-free survival (bDFS) was calculated from the date of surgery and from the end of RT. The multivariate analysis was performed using the Cox Proportional hazard model. Results: In the SM-/LVI- and SM+/LVI- groups, SRT was a significant predictor of a decreased bDFS from the date of surgery, while in the SM+/LVI+ group, there was a trend towards significance. From the end of RT, SRT was also a significant predictor of a decreased bDFS in three patient groups: SM-/LVI-, SM+/LVI- and SM+/LVI+. Gleason score >7 showed to be another factor on multivariate analysis associated with decreased bDFS in the SM-/LVI- group, from the date of surgery and end of RT. Preoperative PSA was a significant predictor in the SM-/LVI- group from the date of RP only. Conclusions: Immediate ART post RP for patients with high risk features in the prostatectomy specimen significantly reduces bDFS after RP compared with early SRT upon PSA relapse.

    Colorectal cancer is one of the most common types of cancer in the Western world. Apart from surgery - which remains the mainstay of treatment for resectable primary tumours - postoperative (i.e., adjuvant) chemotherapy with 5-fluorouracil (5-FU) based regimens is now the standard treatment in Dukes' C (TNM stage III) colon tumours i.e. tumours with metastases in the regional lymph nodes but no distant metastases. In contrast, the evidence for recommendations of adjuvant therapy in rectal cancer is sparse. In Europe it is generally acknowledged that locally advanced rectal tumours receive preoperative (i.e., neoadjuvant) downstaging by radiotherapy (or chemoradiotion), whereas in the US postoperative chemoradiotion is considered the treatment of choice in all Dukes' C rectal cancers. Overall, no universal consensus exists on the adjuvant treatment of surgically resectable rectal carcinoma; moreover, no formal systematic review and meta-analysis has been so far performed on this subject. We undertook a systematic review of the scientific literature from 1975 until March 2011 in order to quantitatively summarize the available evidence regarding the impact of postoperative adjuvant chemotherapy on the survival of patients with surgically resectable rectal cancer. The outcomes of interest were overall survival (OS) and disease-free survival (DFS). CCCG standard search strategy in defined databases with the following supplementary search. 1.

    Unrecognised pregnancy during radioisotope therapy of thyroid cancer results in hardly definable embryo/fetus exposures, particularly when the thyroid gland is already removed. Sources of such difficulty include uncertainty in data like pregnancy commencing time, amount and distribution of metastasized thyroid cells in body, effect of the thyroidectomy on the fetus dose coefficient etc. Despite all these uncertainties, estimation of the order of the fetus dose in most cases is enough for medical and legal decision-making purposes. A model for adapting the dose coefficients recommended by the well-known methods to the problem of fetus dose assessment in athyrotic patients is proposed. The model defines a correction factor for the problem and ensures that the fetus dose in athyrotic pregnant patients is less than the normal patients. A case of pregnant patient undergone post-surgical therapy by I-131 is then studied for quantitative comparison of the methods. The results draw a range for the fetus dose in athyrotic patients using the derived factor. This reduces the concerns on under- or over-estimation of the embryo/fetus dose and is helpful for personal and/or legal decision-making on abortion. (authors)

    Epidermolysis bullosa acquisita (EBA) is an uncommon, acquired, chronic subepidermal bullous disease. This report describes a case of EBA with gingival involvement. A 43-year-old woman with EBA was referred to our clinic for periodontal therapy because of gingival tenderness and bleeding. She has been on cyclosporin A therapy for the last 2 years. Clinical findings were analyzed. Anterior gingivectomy operations were performed in 2 stages. The samples obtained during the surgery were examined using histopathologic, immunohistologic, and electronmicroscopic methods. Long-term effects of the surgical periodontal treatment on gingiva were evaluated both clinically and microscopically. The dentition displayed minimal enamel hypoplasia. Decayed, missing, and filled surfaces score was found to be elevated. Periodontal examination showed generalized diffuse gingival inflammation and gingival enlargement localized mainly to the anterior region. Nikolsky's sign was positive. However, wound healing was uneventful after the operations. Microscopic findings were similar to those obtained from the skin. Twenty-one months after the operations, Nikolsky's sign was negative and no remarkable gingival inflammation was noted. Microscopic examination revealed that the blisters were fewer in number and smaller in size. These results indicate that gingival tissues may also be involved in EBA. Uneventful wound healing after periodontal surgery in this case suggests that periodontal surgery can be performed in patients with EBA. Moreover, both our clinical and histopathologic findings imply that gingivectomy proves useful in maintaining gingival integrity in these patients. Our data may also suggest that the patients with EBA are highly likely to develop dental caries.

    Full Text Available Abstract Background Traction therapy has been utilized in the treatment of low back pain for decades. The most recent incarnation of traction therapy is non-surgical spinal decompression therapy which can cost over $100,000. This form of therapy has been heavily marketed to manual therapy professions and subsequently to the consumer. The purpose of this paper is to initiate a debate pertaining to the relationship between marketing claims and the scientific literature on non-surgical spinal decompression. Discussion Only one small randomized controlled trial and several lower level efficacy studies have been performed on spinal decompression therapy. In general the quality of these studies is questionable. Many of the studies were performed using the VAX-D® unit which places the patient in a prone position. Often companies utilize this research for their marketing although their units place the patient in the supine position. Summary Only limited evidence is available to warrant the routine use of non-surgical spinal decompression, particularly when many other well investigated, less expensive alternatives are available.

    In order to develop ultimate adjuvant therapy for malignant gliomas, we analyzed 77 patients with malignant gliomas (29 anaplastic astrocytomas (AAs) and 48 glioblastoma multiformes (GMs)) treated by three protocols of IMR therapy (human interferon-beta (HuIFN-β), MCNU and radiation). In protocol 1 (n = 45 : AA = 13, GM = 32), 1 x 10 6 IU of HuIFN-β was administrated intravenously once a day for 7 days. On day 2, MCNU was administrated at a dose of 2 mg/kg b.w. intravenously and from day 3, radiation was started in five weekly fractions of 2 Gy for 6 weeks. Total dose was 60 Gy. Protocol 2 (n = 19 : AA = 11, GM = 8) was comparable with protocol 1 except HuIFN-β was administrated twice a day at a dose of 1 x 10 6 IU each. Protocol 3 (n = 13 : AA = 5, GM = 8) differed from protocol 2 only in a high dose-hyperfractionated radiation which was given twice a day at a dose of 1.5 Gy each and for a total dose of 66 Gy. Antitumor effects were evaluated by survival and response rate determined by decrease of tumor size. Significant improvement was obtained in patients with AAs by protocol 2 and 3. Response rates of patients with AAs and GMs were 46.2 % and 50 % in protocol 1, 63.6 % and 50 % in protocol 2, and 80 % and 50 % in protocol 3, respectively. One and two year survival rates in AAs were 46.4 % and 34.8 % in protocol 1, both 75 % in protocol 2, and both 100 % in protocol 3. Survival rates in GMs were not different among them. Except of radiation necrosis, which was observed in 38.5 % of the patients under protocol 3, there was no significant difference in the adverse effects among the three protocols. In the present study, the efficacy of IMR therapy for patients with malignant gliomas, especially for AAs, was confirmed. We conclude that twice a day administrations of HuIFN-β in combination with a high dose-hyperfractionated radiation provide increased efficacy in IMR therapy. (author)

    Purpose: Locoregional recurrence is common after surgery for gastric cancer. Adjuvant therapy improves outcomes but with toxicity. This phase 1/2 study investigated infusional 5-fluorouracil (5-FU) in combination with biweekly cisplatin delivered concurrently with image guided high-precision radiation therapy. Methods and Materials: Eligible patients had completely resected stage IB to IV (Union for International Cancer Control TNM 6th edition) nonmetastatic gastric adenocarcinoma. Treatment constituted 12 weeks of infusional 5-FU (200 mg/m{sup 2}/day) with cisplatin added in a standard 3 + 3 dose escalation protocol (0, 20, 30, and 40 mg/m{sup 2}) during weeks 1, 3, 5, and 7, and an additional week 9 dose in the final cohort. Radiation therapy (45 Gy in 25 fractions) was delivered during weeks 3 to 7. Maximum tolerated dose (MTD) was determined in phase 1 and confirmed in phase 2. Results: Among the 55 patients (median age, 54 years; range 28-77 years; 55% male), the median follow-up time was 3.0 years (range, 0.3-5.3 years). Five patients in phase 1 experienced dose-limiting toxici
