    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.

    Breast cancer is the most common cause of cancer and cancer death worldwide. Although most patients present with localized breast cancer and may be rendered disease-free with local therapy, distant recurrence is common and is the primary cause of death from the disease. Adjuvant systemic therapies are effective in reducing the risk of distant and local recurrence, including endocrine therapy, anti-HER2 therapy, and chemotherapy, even in patients at low risk of recurrence. The widespread use of adjuvant systemic therapy has contributed to reduced breast cancer mortality rates. Adjuvant cytotoxic chemotherapy regimens have evolved from single alkylating agents to polychemotherapy regimens incorporating anthracyclines and/or taxanes. This review summarizes key milestones in the evolution of adjuvant systemic therapy in general, and adjuvant chemotherapy in particular. Although adjuvant treatments are routinely guided by predictive factors for endocrine therapy (hormone receptor expression) and anti-HER2 therapy (HER2 overexpression), predicting benefit from chemotherapy has been more challenging. Randomized studies are now in progress utilizing multiparameter gene expression assays that may more accurately select patients most likely to benefit from adjuvant chemotherapy.

    Postoperative combined modality therapy with radiotherapy and 5-fluorouracil (5FU) chemotherapy is an effective adjuvant approach that reduces locoregional and distant metastatic disease in patients with high-risk rectal carcinoma. However, this approach results in a treatment regimen of at least 6 months` duration. The present prospective study investigates the integration of radiotherapy and 5FU chemotherapy in a protocol designed to minimize toxicity and reduce the overall treatment time. A total of 40 patients with TNM stage 11 or 111 disease receives postoperative radiotherapy at four fractions per week with weekly 5FU bolus injections delivered on the fifth non radiotherapy day. Patients also received systemic chemotherapy with leucovorin both before and after pelvic irradiation, with the total treatment duration extending for only 18 weeks. Patients were able to complete radiotherapy in 90% of cases, while the delivery of full-dose chemotherapy was achievable in the vast majority. The incidence of haematologic and gastrointestinal toxicities requiring the cessation of treatment was acceptable. With a median follow-up of 20.9 months among surviving patients, the estimated progression-free and overall survival at 2 years were 71% and 79%, respectively.

    2004-11-01

    Full Text Available BACKGROUND: Molecular predictors for the effectiveness of adjuvant chemotherapy in colorectal cancer are of considerable clinical interest. To this aim, we analyzed the serine threonine receptor-associated protein (STRAP, an inhibitor of TGF-βsignaling, with regard to prognosis and prediction of adjuvant 5-FU chemotherapy benefit. i The gene copy status of STRAP was determined using quantitative realtime polymerase chain reaction in 166 colorectal tumor biopsies, which had been collected from a randomized multicenter trial of 5-fluorouracil (5-FU/mitomycin C (MMC adjuvant chemotherapy of the Swiss Group for Clinical Cancer Research (SAKK. RESULTS: Amplification of STRAP was found in 22.8% of the tumors. When left without adjuvant chemotherapy, patients bearing tumors with a STRAP amplification had a significantly better prognosis (hazard ratio for death: 0.26; P = .004. Interestingly, these patients, when receiving adjuvant treatment, had a worse survival (hazard ratio for death: 3.48; P = .019 than without chemotherapy, whereas patients carrying tumors with diploidy or deletion of STRAP benefited from the treatment (hazard ratio for death: 0.44; P = .052. This suggests the amplification of STRAP as a strong predictor of an unfavorable effect of 5-FU-based adjuvant chemotherapy. CONCLUSION: If confirmed, the STRAP gene copy status might provide a parameter to decide about the use of 5-FU-based adjuvant chemotherapy.

    2009-10-01

    Full Text Available For many years, surgery alone was the standard treatment for patients with stage I-IIIA non-small-cell lung cancer (NSCLC. However, recent studies have demonstrated that adjuvant chemotherapy provides a survival benefit. The first adjuvant chemotherapy for NSCLC was performed in the 1960s using a key drug known as cyclophosphamide. In the 1980s and early 1990s, a new anti-cancer drug, cisplatin, was developed. The first meta-analysis of this drug was conducted by the Non-small Cell Lung Cancer Collaborative Group in 1995. This analysis comparing surgery with surgery plus chemotherapy containing cisplatin produced a hazard ratio of 0.87 and suggested an absolute benefit of chemotherapy of 5% at 5 years;this difference was not statistically significant (p0.08. Several clinical trials of adjuvant chemotherapy were planned after the meta-analysis conducted in 1995, but the efficacy of adjuvant chemotherapy remained a matter of controversy. However, useful evidence was reported after 2003. The International Adjuvant Lung Cancer Collaborative Group Trial (IALT demonstrated a 4.1% improvement in survival for patients with stage I to III NSCLC. The JBR. 10 trial demonstrated a 15% improvement in 5-year survival for the adjuvant chemotherapy arm in stage IB or II (excluding T3N0 patients. The Adjuvant Navelbine International Trialist Association (ANITA trial reported that the overall survival at 5 years improved by 8.6% in the chemotherapy arm and that this survival rate was maintained at 7 years (8.4% in stage II and IIIA patients. A meta-analysis based on collected and pooled individual patient data from the 5 largest randomized trials was conducted by the Lung Adjuvant Cisplatin Evaluation (LACE. This analysis demonstrated that cisplatin-based adjuvant chemotherapy improved survival in patients with stage II or III cancer. Alterna-tively, uracil-tegafur has been developed and tested in Japan.

    Full Text Available OBJECTIVE: We examined our database of patients undergoing radical cystectomy (RC with orthotopic neobladder (NB to determine whether adjuvant chemotherapy in this group is safe. MATERIALS AND METHODS: We performed a retrospective analysis of patients who underwent radical cystectomy and urinary diversion between 1992 and 2004. Relevant clinical and therapeutic data were entered into a database. High-risk bladder cancer patients who underwent NB were identified. They were stratified into 2 groups, those who received adjuvant chemotherapy and those who did not. The incidence of complications between the 2 groups was analyzed and compared. RESULTS: Over the 12-year period, 136 patients underwent RC and NB construction for bladder cancer. Of these, 83 patients were at high risk for recurrence. Nineteen patients received adjuvant chemotherapy and 64 did not. The complication rate in the adjuvant chemotherapy group was 53% and it was 23% in those who did not receive chemotherapy. There were no perioperative or treatment related death. There were 2 patients with grade 4 toxicity in the adjuvant chemotherapy group. There was a statistical difference between these two groups with regard to the incidence of complications. However, none of these complications was life-threatening, required only conservative treatment and caused no long-term disability. CONCLUSIONS: Adjuvant chemotherapy is a safe treatment for patients undergoing RC and NB substitution. Hence, the option of orthotopic NB should not be denied in selected bladder cancer patients with high risk for recurrent disease.

Patients and methods: Eighty-two postmenopausal women with estrogen receptor-positive, human epidermal growth-factor receptor 2-negative breast cancer who had completed adjuvant chemotherapy were asked about their preferred route of administration of chemotherapy and the reason. Women also answered questions about their physical and psychological status and quality of life during chemotherapy. Results: Patients who had received oral chemotherapy preferred it more frequently than those who had received intravenous chemotherapy (100% versus 37%, respectively, chi-square =15.5; P<0.001. Patients who preferred the same route of administration of chemotherapy as they had previously received showed a significantly better psychological status during chemotherapy compared with those who preferred a different route. Conclusion: Our study showed that preferences for oral and intravenous chemotherapy strongly depended on the actual prior administration of chemotherapy and patients' own experiences during chemotherapy.

    1999-01-01

    Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage Ⅰ-Ⅲ) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX)300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 d1,cisplatin (DDP) 20 mg/m2, d1-5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600-900 mg/d for 1year (adjuvant chemotherapy group). The other 35patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4%in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage Ⅲwas 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage Ⅰ-Ⅱ in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage Ⅲ, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

    Full Text Available Abstract Background Although adjuvant gemcitabine (GEM chemotherapy for pancreatic cancer is standard, the quality of life (QOL in those patients is still impaired by the standard regimen of GEM. Therefore, we studied whether mild dose-intensity adjuvant chemotherapy with bi-weekly GEM administration could provide a survival benefit with acceptable QOL to the patients with pancreatic cancer. Methods After a phase I trial, an adjuvant bi-weekly 1,000 mg/m2 of GEM chemotherapy was performed in 58 patients with pancreatic cancer for at least 12 courses (Group A. In contrast, 36 patients who declined the adjuvant bi-weekly GEM chemotherapy underwent traditional adjuvant 5FU-based chemotherapy (Group B. Careful periodical follow-ups for side effects of GEM and disease recurrence, and assessment of patients’ QOL using the EORTC QOL questionnaire (QLQ-C30 and pancreatic cancer-specific supplemental module (QLQ-PAN26 were performed. Retrospectively, the degree of side effects, patients’ QOL, compliance rate, disease-free survival (DFS, and overall survival (OS in Group A were compared with those in Group B. Results No severe side effects (higher than Grade 2 according to the common toxicity criteria of ECOG were observed, except for patients in Group B, who were switched to the standard GEM chemotherapy. Patients’ QOL was better in Group A than B (fatigue: 48.9 ± 32.1 versus 68.1 ± 36.3, nausea and vomiting: 26.8 ± 20.4 versus 53.7 ± 32.6, diarrhea: 21.0 ± 22.6 versus 53.9 ± 38.5, difficulty gaining weight: 49.5 ± 34.4 versus 67.7 ± 40.5, P P P Conclusions Adjuvant chemotherapy with bi-weekly GEM offered not only the advantage of survival benefits but the excellent compliance with acceptable QOL for postoperative pancreatic cancer patients.

    Full Text Available Abstract Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0, and to obtain the utility value by the standard gamble (SG and visual scale (VS methods. Total medical cost was assessed from the (National Health Insurance NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

    2016-06-01

    The standard treatment in children with average-risk medulloblastoma (MB) is reduced-dose radiotherapy (RT) followed by chemotherapy. However, in adults, there is no agreement on the use of adjuvant chemotherapy. We performed a retrospective analysis of adult MB patients with average-risk disease, defined as no postsurgical residual (or ≤1.5 cm(2)) and no metastatic disease (M0). Main inclusion criteria were: age >16 years, post-surgical treatment with craniospinal irradiation with or without adjuvant chemotherapy (cisplatin and etoposide ± cyclophosphamide). From 1988 to 2012 were accrued 43 average-risk MB patients treated with surgery and adjuvant RT. Fifteen (34.9 %) patients received also chemotherapy: 7 before RT, 5 after RT, and 3 before and after RT. Reasons to administer chemotherapy were presence of residual disease (even if ≤1.5 cm) and delay in RT. After a median follow up time of 10 years (range: 8-13), median survival was 18 years (95 % CI 9-28) in patients who receive RT alone, and was not reached in patients treated with RT plus chemotherapy. The survival rates at 5, 10 and 15 years were 100 %, 78.6 % (95 % CI 60.0-97.2 %) and 60.2 % (95 % CI 36.9-83.5 %), in patients treated with RT alone, and 100, 100 and 100 %, in patients treated with RT plus chemotherapy (p = 0.079). Our findings suggest a role for adjuvant chemotherapy in the treatment of average-risk MB adult patients. Further improvements might drive to add chemotherapy in average-risk setting with less favourable biological signatures (i.e., non-WNT group).

  7. Adjuvant chemotherapy in soft tissue sarcomas…Conflicts, consensus, and controversies

    Directory of Open Access Journals (Sweden)

    Jyoti Bajpai

    2016-01-01

    Full Text Available Soft tissue sarcomas (STSs are an uncommon and diverse group of more than 50 mesenchymal malignancies. Each of these histologic subtypes represents a unique disease with distinct biologic behavior and varying sensitivity to chemotherapy. The judicious use of adjuvant/neoadjuvant chemotherapy along with surgery and radiation in the treatment of localized STS has a role in improving patient outcomes by decreasing local and distant recurrences. There is evidence that the use of adjuvant chemotherapy to a mixed cohort of chemo sensitive and insensitive sarcoma subtypes results in limited benefit. Therefore, it is of paramount importance to identify the subpopulation with high metastatic potential and to identify effective histology-specific treatment options to these patients. Present perspective, will focus on the rationale for adjuvant chemotherapy in sarcoma, with emphasis on the histology driven chemotherapy. It will outline key therapeutic opportunities and hurdles in adjuvant medical treatment of sarcoma, focusing on specific subtypes that are on the verge of new breakthroughs, as well as those in which promise has not lived up to expectations.

    Cognitive deficits are found in a number of breast-cancer patients who have undergone adjuvant (Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF)) chemotherapy, but the underlying mechanisms are still unclear. The objective of this study is to investigate information processing in these patients with concurrent registration of brain activity. Twenty-six breast-cancer patients treated with adjuvant CMF chemotherapy and a control group of 23 stage I breast-cancer patients not treated with chemotherapy were examined. Mean time since treatment for the CMF patients was 5.1 years after the last CMF course, and for the control patients 3.6 years after termination of radiotherapy. An information processing task was administered with concurrent EEG registration. Reaction times and the amplitudes and latencies of an Event Related Potential component (P3) in different task conditions related to input, central, and output processing of information were studied. Significant differences in latency and amplitude of the P3 component were found between the treatment groups with an earlier and reduced P3 in the chemotherapy group. Patients treated with chemotherapy had longer reaction times (although not significantly different) than the control group on all task conditions. Our data provide further evidence for long-term neurocognitive problems in breast-cancer patients treated with adjuvant (CMF) chemotherapy and offer new information regarding abnormalities in brain functioning in these patients.

    Full Text Available Although rare, clinicians and patients must be aware that therapy related malignancies, specifically acute myeloid leukemia (AML, can occur as a complication of adjuvant chemotherapy for breast cancer. Vigilance for signs and symptoms is appropriate. AML with t (8;16 is a specific translocation leading to formation of a fusion protein (MYST3/CREBBP. The MYST3/CREBBP AML tends to develop within 2 years of adjuvant chemotherapy, especially for breast cancer, without preceding myelodysplasia. It usually presents with disseminated intravascular coagulation and osteolytic lesions and has a poor prognosis despite aggressive resuscitation and therapy. With the increasing use of adjuvant chemotherapy for breast cancer, we are seeing a definite increase in the incidence of therapy related myelodysplastic syndromes and AML. One must keep this complication in mind while counseling and following up breast cancer patients who have received adjuvant chemotherapy. New osteolytic bone lesions in a patient with history of breast cancer do not necessarily mean metastatic disease and should be fully evaluated.

    Being the second cancer for men and the third cancer for women in France, colorectal cancer represents a serious public health issue. Its incidence has increased these last years and despite new therapeutics being developed, it still has a bad prognostic. Thanks in part to Hemoccult national mass screening program, its diagnosis is made possible at an earlier stage, which makes a surgical curative resection and the carrying out of adjuvant chemotherapy possible. For stage III colic cancer that has been surgically removed, adjuvant chemotherapy by FOLFOX 4 has to be offered. Nevertheless, because of its toxicities, the patient's high age, important comorbidities or post-surgical complications, this chemotherapy occasionally cannot be done. What are the colorectal cancer prognostic factors which would guide the chemotherapy? TNM classification, number of examined lymph nodes, MSI status, and presence or not of a perforation or a perinervous, lymphatic or venous invasion is recognized prognostic factors. Also, what are the alternatives of FOLFOX 4 regimen as colorectal cancer adjuvant treatment?

    Adjuvant chemotherapy is often needed to achieve adequate breast cancer control. The increasing popularity of immediate breast reconstruction (IBR) raises concerns that this procedure may delay the time to adjuvant chemotherapy (TTC), which may negatively impact oncological outcome. The current systematic review aims to investigate this effect. During October 2014, a systematic search for clinical studies was performed in six databases with keywords related to breast reconstruction and chemotherapy. Eligible studies met the following inclusion criteria: (1) research population consisted of women receiving therapeutic mastectomy, (2) comparison of IBR with mastectomy only groups, (3) TTC was clearly presented and mentioned as outcome measure, and (4) original studies only (e.g., cohort study, randomized controlled trial, case-control). Fourteen studies were included, representing 5270 patients who had received adjuvant chemotherapy, of whom 1942 had undergone IBR and 3328 mastectomy only. One study found a significantly shorter mean TTC of 12.6 days after IBR, four studies found a significant delay after IBR averaging 6.6-16.8 days, seven studies found no significant difference in TTC between IBR and mastectomy only, and two studies did not perform statistical analyses for comparison. In studies that measured TTC from surgery, mean TTC varied from 29 to 61 days for IBR and from 21 to 60 days for mastectomy only. This systematic review of the current literature showed that IBR does not necessarily delay the start of adjuvant chemotherapy to a clinically relevant extent, suggesting that in general IBR is a valid option for non-metastatic breast cancer patients.

    Objective:Survival and treatment of patients with microinvasive breast cancer (MIBC) remain controversial. In this paper, we evaluated whether adjuvant chemotherapy is necessary for patients with MIBC to identify risk factors influencing its prognosis and decide the indication for adjuvant chemotherapy. Methods:In this retrospective study, 108 patients with MIBC were recruited according to seventh edition of the staging manual of the American Joint Committee on Cancer (AJCC). The subjects were divided into chemotherapy and non-chemotherapy groups. We compared the 5-year disease-free survival (DFS) and overall survival (OS) rates between groups. Furthermore, we analyzed the factors related to prognosis for patients with MIBC using univariate and multivariate analyses. We also evaluated the impact of adjuvant chemotherapy on the prognostic factors by subgroup analysis after median follow-up time of 33 months (13-104 months). Results:The 5-year DFS and OS rates for the chemotherapy group were 93.7% and 97.5%, whereas those for the non-chemotherapy group were 89.7% and 100%. Results indicate that 5-year DFS was superior, but OS was inferior, in the former group compared with the latter group. However, no statistical significance was observed in the 5-year DFS (P=0.223) or OS (P=0.530) rate of the two groups. Most relevant poor-prognostic factors were Ki-67 overexpression and negative hormonal receptors. Cumulative survival was 98.2%vs. 86.5% between low Ki-67 (≤20%) and high Ki-67 (>20%). The hazard ratio of patients with high Ki-67 was 16.585 [95% confidence interval (CI), 1.969-139.724;P=0.010]. Meanwhile, ER(-)/PR(-) patients with MIBC had cumulative survival of 79.3% compared with 97.5% for ER(+) or PR(+) patients with MIBC. The hazard ratio for ER(-)/PR(-) patients with MIBC was 19.149 (95% CI, 3.702-99.057;P<0.001). Subgroup analysis showed that chemotherapy could improve the outcomes of ER(-)/PR(-) patients (P=0.014), but not those who overexpress Ki-67 (P=0

    We assigned 91 patients with deeply invasive, pathological stage P3, P4 or N+ and Mo transitional cell carcinoma of the bladder (with or without squamous or glandular differentiation) to adjuvant chemotherapy or to observation after radical cystectomy and pelvic lymph node dissection. For most patients chemotherapy was planned as 4 courses at 28-day intervals of 100 mg./M.2 cisplatin, 60 mg./M.2 doxorubicin and 600 mg./M.2 cyclophosphamide. A significant delay was shown in the time to progression (p = 0.0010) with 70% of the patients assigned to chemotherapy free of disease at 3 years compared to 46% in the observation group. Median survival time for patients in the chemotherapy group was 4.3 years compared to 2.4 years in the observation group (p = 0.0062). In addition to treatment groups, important prognostic factors included age, gender and lymph node status. The number of involved lymph nodes was the single most important variable. We recommend adjuvant chemotherapy for patients with invasive transitional cell carcinoma after definitive surgical resection.

    The aim of adjuvant chemotherapy is the destruction of micrometastases after surgical removal of a malignant tumor. This treatment modality is gaining in importance in the light of experimental data and lcinical success in pediatric tumors. Results of ongoing studies in colo-rectal cancer show a marginal effect of prophylactic treatment with 5-fluorouracil. The treatment benefits in trials with historical controls are much greater than in studies with simultaneous controls. Use of historical controls is therefore of doubtful value. Ongoing trials use the combination of 5-fluorouracil and methyl-CCNU, which has been shown to double the remission rate in advanced gastrointestinal cancer. Adjuvant chemotherapy of colo-rectal cancer is still experimental and justified only in the framework of clinical trials.

    @@ Glioblastoma multiforme (GBM) is the most common primary malignant brain tumor in adults, which accounts for approximately 50% of all gliomas. Its prognosis is particularly disappointing with a median life expectancy less than a year even when the patients are treated with the most aggressive regimens.1 Over the past 10 years, a number of trials have tried to establish whether adjuvant chemotherapy, as well as molecularly targeted therapy, provides GBM patients with clinically meaningful benefits.

    A 70-year-old man was referred to our hospital with ascending colon cancer (cT3N1M0, Stage IIIa), which was found during examinations following a positive fecal occult blood test. The patient was also diagnosed with early gastric cancer (cT1a, N0, M0, Stage IA)during a preoperative gastroscopy examination. A laparoscopically assisted right colectomy and D3 lymphadenectomy was performed for the ascending colon cancer. The postoperative pathological diagnosis was Stage IIIb (pT3N2), he was administered in combination with capecitabine plus oxaliplatin (CapeOX) as adjuvant chemotherapy before the treatment for the colon cancer. After 6 months of adjuvant chemotherapy, we were unable to detect any gastric lesions at the same location using gastroscopy, and so diagnosed a clinical complete response. A follow-up gastroscopy 6 months later showed the same findings. The patient has had no recurrence of gastric cancer for 18 months after the initial operation. He will continue to be followed up closely using gastroscopy. In this case, CapeOX as adjuvant chemotherapy for advanced colon cancer was also effective for early gastric cancer.

    2014-01-01

    Background: Breast cancer (BC) is the leading cause of cancer death in Chilean women. Adjuvant chemotherapy decreases recurrence and death from BC. The recommendation to indicate chemotherapy is complex. Adjuvant! Online is a valuable computational tool to predict survival benefit obtained with adjuvant systemic therapy. Previous studies in Caucasian patients with BC showed that they are willing to receive chemotherapy for a small benefit. No studies, to our knowledge, have been done in the Hispanic or Latino populations. Methods: We interviewed females with BC who had previously received adjuvant chemotherapy. Age, stage at presentation, time since last chemotherapy, type of chemotherapy, marital status, number of children, and level of education were recorded. We used the graphic representation from Adjuvant! Online to question each patient on how much survival benefit she required to accept chemotherapy. Results: There were 101 women surveyed. The average age was 55.9 (±10.2), 54.5% had involved lymph nodes, 59.4% were married, and 15.8% did not have parity; 62.3% of females accepted chemotherapy for an absolute survival benefit of 1% or less. In a multivariate analysis, younger (p = 0.02) and less-educated patients (p = 0.018) were associated with lower survival benefit required to opt for chemotherapy. Conclusion: In our study, the acceptance of chemotherapy by the Hispanic population requires minimal survival benefit and is in agreement with the Caucasian population reported elsewhere. To our knowledge, our report is the first study that evaluates the perception of Latino patients regarding the benefit of chemotherapy in early BC. PMID:24678346

    More than half the patients with rectal cancer present with locally advanced rectal disease at diagnosis with a high risk of recurrence. Preoperative chemoradiotherapy and standardized radical surgery with total mesorectal excision have been established as the 'gold standard' for treating these patients. Pathological staging using the ypTNM classification system to decide on adjuvant chemotherapy (ACT) is widely used in clinical practice, but the delivery of ACT is still controversial, as many discrepancies persist in the conclusions of different trials, due to heterogeneity of the inclusion criteria between studies, lack of statistical power, and variations in preoperative and adjuvant regimens. In 2014, a meta-analysis of four randomized phase-III trials (EORTC 22921, I-CNR-RT, PROCTOR-SCRIPT, CHRONICLE) failed to demonstrate any statistical efficacy of fluorouracil (5FU)-based ACT. Three recent randomized trials aimed to compare 5FU with 5FU plus oxaliplatin-based chemotherapy. Two of them (ADORE, CAO/ARO/AIO-04) appeared to find a disease-free survival benefit for patients treated with the combination therapy. Thus, while awaiting new data, it can be said that, as of 2015, patients with yp stage I tumors or histological complete response derived no benefit from adjuvant therapy. On the other hand, the FOLFOX chemotherapy regimen should be proposed for yp stage III patients, and may be considered for yp stage II tumors in fit patients with high-risk factors. Nevertheless, well-designed and sufficiently powered clinical trials dedicated to adjuvant treatments for rectal cancer remain justified in future to achieve a high level of proof in keeping with evidence-based medical standards.

    Full Text Available Abstract Background Diagnosis of breast cancer during pregnancy was formerly considered an indication for abortion. The pendulum has since swung to the other extreme, with most reviews now rejecting termination while endorsing immediate anthracycline-based therapy for any pregnant patient beyond the first trimester. To assess the evidence for this radical change in thinking, a review of relevant studies in the fields of breast cancer chemotherapy, pregnancy, and drug safety was conducted. Discussion Accumulating evidence for the short-term safety of anthracycline-based chemotherapy during late-trimester pregnancy represents a clear advance over the traditional norm of therapeutic abortion. Nonetheless, the emerging orthodoxy favoring routine chemotherapy during gestation should continue to be questioned on several grounds: (1 the assumed difference in maternal survival accruing from chemotherapy administered earlier – i.e., during pregnancy, rather than after delivery – has not been quantified; (2 the added survival benefit of adjuvant cytotoxic therapy prescribed within the hormone-rich milieu of pregnancy remains presumptive, particularly for ER-positive disease; (3 the maternal survival benefit associated with modified adjuvant regimens (e.g., weekly schedules, omission of taxanes, etc. has not been proven equivalent to standard (e.g., post-delivery regimens; and (4 the long-term transplacental and transgenerational hazards of late-trimester chemotherapy are unknown. Summary Although an incrementally increased risk of cancer-specific mortality is impossible to exclude, mothers who place a high priority on the lifelong well-being of their progeny may be informed that deferring optimal chemotherapy until after delivery is still an option to consider, especially in ER-positive, node-negative and/or last-trimester disease.

    Full Text Available Abstract Background Adjuvant chemotherapy has been shown to improve survival rates of postoperative patients with non-small cell lung cancer (NSCLC. Biomarkers could help select an appropriate chemotherapy for NSCLC patients or predict the efficacy of chemotherapy. The objective of this study was to explore the possible prognostic and predictive role of topoisomerase II alpha (TopIIα expression level in postoperative NSCLC patients who received adjuvant chemotherapy. Methods Patients with stage I-III NSCLC, who underwent surgery in our hospital from January 2004 to December 2007 and who also received adjuvant chemotherapy after surgery, were analyzed in this study. Expression of TopIIα and Ki67 in paraffin-embedded tissues was detected by immunohistochemistry (IHC. The relationships between clinicopathological characteristics, chemotherapy regimens, the expression of biomarkers and disease free survival (DFS were analyzed. Results TopIIα and Ki67 were highly expressed in 22.5% and 36.4% of the 151 patients, respectively. Univariate survival analysis showed that male sex (P = 0.036, non-adenocarcinoma (P = 0.004, earlier pathological TNM stage (P = 0.001 or pathological N stage (P Conclusions High TopIIα expression was discovered to be correlated with better DFS for postoperative NSCLC patients who received adjuvant chemotherapy. The NVB-containing chemotherapy regimen was more effective than the TXT-containing regimen in improving DFS in patients with low TopIIα expression. TopIIα could be considered to be an independent prognostic biomarker of DFS in postoperative NSCLC patients who received adjuvant chemotherapy.

    Full Text Available A meta-analysis was performed to quantify the magnitude and nature of the association between adjuvant chemotherapy and performance on a range of cognitive domains among breast cancer patients. A total of 27 studies (14 cross-sectional, 8 both cross-sectional and prospective and 5 prospective were included in the analyses, involving 1562 breast cancer patients who had undergone adjuvant chemotherapy and 2799 controls that included breast cancer patients who did not receive adjuvant chemotherapy. A total of 737 effect sizes (Cohen’s d were calculated for cross-sectional and prospective longitudinal studies separately and classified into eight cognitive domains. The mean effect sizes varied across cross-sectional and prospective longitudinal studies (ranging from –1.12 to 0.62, and –0.29 to 1.12, respectively. Each cognitive domain produced small effect sizes for cross sectional and prospective longitudinal studies (ranging from –0.25 to 0.41. Results from cross-sectional studies indicated a significant association between adjuvant chemotherapy and cognitive impairment that held across studies with varied methodological approaches. For prospective studies, results generally indicated that cognitive functioning improved over time after receiving adjuvant chemotherapy. Greater cognitive impairment was reported in cross-sectional studies comparing chemotherapy groups with healthy control groups. Results suggested that cognitive impairment is present among breast cancer patients irrespective of a history of chemotherapy. Prospective longitudinal research is warranted to examine the degree and persisting nature of cognitive impairment present both before and after chemotherapy, with comparisons made to participants’ cognitive function prior to diagnosis. Accurate understanding of the effects of chemotherapy is essential to enable informed decisions regarding treatment and to improve quality of life among breast cancer patients.

    Chemotherapy-related amenorrhea (CRA) is associated with infertility and menopausal symptoms. Learning how frequently paclitaxel and trastuzumab cause amenorrhea is important. Most other adjuvant breast cancer therapies induce CRA in approximately 50 % of all premenopausal recipients [1]. 410 patients enrolled on the APT Trial, a single-arm phase 2 adjuvant study of 12 weeks of paclitaxel and trastuzumab followed by nine months of trastuzumab monotherapy. Eligible patients had ≤3 cm node-negative HER2 + breast cancers. Premenopausal enrollees were asked to complete menstrual surveys every 3-12 months for 72 months. Women who responded to at least one survey at least 15 months after chemotherapy initiation (and who did not undergo hysterectomy and/or bilateral oophorectomy or receive ovarian suppressing medications prior to 15 months) were included in this analysis. A participant was defined as having amenorrhea in follow-up if her self-reported last menstrual period at last follow-up was greater than 12 months prior to the survey. Among the 64 women in the evaluable population (median age at study entry 44 years, range 27-52 years), the median time between chemotherapy initiation and last menstrual survey was 51 months (range 16-79). 18 of 64 women (28 %, 95 % CI 18-41 %) were amenorrheic at that time point. Amenorrhea rates among premenopausal women treated with adjuvant paclitaxel and trastuzumab for early stage breast cancer appear lower than those seen historically with standard alkylator-based breast cancer regimens. Future studies are needed to understand the impact of this regimen on related issues of fertility and menopausal symptoms.

    In 1990, an international consensus was reached on the efficacy of adjuvant chemotherapy for lymph node positive (stage III) colon carcinoma (CC). This study evaluates the use and benefit of such therapy in routine health care practice. The study includes all patients with stage III CC treated by putative curative surgery (n = 182) recorded at the Geneva cancer registry between 1990 and 1996. Factors modifying chemotherapy use were determined by logistic regression, considering patients with chemotherapy as cases (n = 55) and others as controls (n = 127). The effect of chemotherapy on the 5-year survival was evaluated by the Cox model. Analyses were adjusted for possible confounders. The use of chemotherapy increased over the period (P(trend) < 0.001). Age strongly modulated chemotherapy use. In 1996, 54% of eligible patients received chemotherapy, this proportion fell to 13% after age 70. Decisions to use chemotherapy significantly depended on stage, grade and cancer site. The chance to be treated was non-significantly lower among individuals of low social class, widowed and foreigners. Chemotherapy significantly decreased mortality rates (Hazard ratio: 0.35, 95%CI: 0.18-0.68), independently of the prognostic factors and with similar benefit regardless of stage and age group. Strong beneficial effect of adjuvant chemotherapy on stage III CC can be achieved in routine practice. However, this study shows that it is probably not optimally utilised in Switzerland, particularly among the elderly.

    Full Text Available Objective. In a randomized trial of women with early stage breast cancer undergoing adjuvant chemotherapy, two stress management interventions, tai chi training and spiritual growth groups, were compared to a usual care control group, to evaluate psychosocial functioning, quality of life (QOL, and biological markers thought to reflect cancer- and treatment-specific mechanisms. Method. The sample consisted of 145 women aged 27–75 years; 75% were Caucasian and 25% African American. A total of 109 participants completed the study, yielding a 75% retention rate. Grounded in a psychoneuroimmunology framework, the overarching hypothesis was that both interventions would reduce perceived stress, enhance QOL and psychosocial functioning, normalize levels of stress-related neuroendocrine mediators, and attenuate immunosuppression. Results. While interesting patterns were seen across the sample and over time, the interventions had no appreciable effects when delivered during the period of chemotherapy. Conclusions. Findings highlight the complex nature of biobehavioral interventions in relation to treatment trajectories and potential outcomes. Psychosocial interventions like these may lack sufficient power to overcome the psychosocial or physiological stress experienced during the chemotherapy treatment period. It may be that interventions requiring less activity and/or group attendance would have enhanced therapeutic effects, and more active interventions need to be tested prior to and following recovery from chemotherapy.

    With the aging of the Chinese population, it seems obvious that the number of elderly patients with the disease of colorectal carcinoma grows significantly. Meanwhile, no evidence-based practical guideline for the treatment of colorectal carcinoma are available in this particular age group. Therefore, the concept of integrative management has been brought up by the Colorectal Cancer Center of the Second Affiliated Hospital of Zhejiang University, which combines the processes of surgery, perioperative rehabilitation and adjuvant chemotherapy together. In this way, the cooperation and complementarity between different clinical departments could cooperate and complete tasks together to integrate the treatment processes into a cohesive one. To achieve the goal of integrative management, the project is divided into horizontal and vertical aspects. The horizontal integration means the cooperation between different clinical departments, which is also known as multi-discipline treatment (MDT). The vertical integration reflects the completeness of the entire treatment under the goal of consistency, strictness and job separation, which could also be explained as the clinical pathway. Furthermore, this review stresses on the integrative strategy of both clinical and biochemical indexes rehabilitation, as well as the operation and postoperative adjuvant chemotherapy which has been put in execution several years by the Colorectal Cancer Center of the Second Affiliated Hospital of Zhejiang University.

    Full Text Available Abstract Adjuvant chemotherapy for non-small-cell lung carcinoma (NSCLC is a debated issue in clinical oncology. Although it is considered a standard for resected stage II-IIIA patients according to the available guidelines, many questions are still open. Among them, it should be acknowledged that the treatment for stage IB disease has shown so far a limited (if sizable efficacy, the role of modern radiotherapies requires to be evaluated in large prospective randomized trials and the relative impact of age and comorbidities should be weighted to assess the reliability of the trials' evidences in the context of the everyday-practice. In addition, a conclusive evidence of the best partner for cisplatin is currently awaited as well as a deeper investigation of the fading effect of chemotherapy over time. The limited survival benefit since first studies were published and the lack of reliable prognostic and predictive factors beyond pathological stage, strongly call for the identification of bio-molecular markers and classifiers to identify which patients should be treated and which drugs should be used. Given the disappointing results of targeted therapy in this setting have obscured the initial promising perspectives, a biomarker-selection approach may represent the basis of future trials exploring adjuvant treatment for resected NSCLC.

    l-leucovorin (LV)/5-fluorouracil (5FU) may play an important role, as an adjuvant chemotherapy, in improving the survival of patients with stage III colorectal cancer. However, severe toxicity of the chemotherapeutic agent could be fatal. Adverse effects, including bone marrow suppression, liver damage, renal damage, and glucose tolerance, were evaluated daily during 3 courses of l-LV/5FU-modified RPMI regimen adjuvant chemotherapy for 22 patients with stage III colorectal cancer. Decrease in the serum levels of neutrophils and platelets occurred in the 1st course, which became more obvious after three or four administrations of l-LV/5FU in the 1st course. Furthermore, serum levels of leukocytes, neutrophils, and platelets on the re-start day of this chemotherapy after 2-week intervals were lower than those on the start day of this chemotherapy. In the evaluation of liver damage, renal damage, and glucose tolerance; serum alanine aminotransferase level in the 2nd course, serum total bilirubin (T.Bil) level in the 1st course, and serum creatinine level in the 1st course deteriorated during the course. T.Bil levels on the re-start day of this chemotherapy after 2-week intervals were especially high compared to that on the start day. The more courses of this chemotherapy we perform, the more attention we must pay to bone marrow suppression and hyperbilirubinemia. Thus, we clarified the attentive point of side effect of l-LV/5FU adjuvant chemotherapy for colorectal cancer.

    Deficiencies in DNA mismatch repair have been associated with inferior response to 5-FU in colorectal cancer. Pancreatic ductal adenocarcinoma is similarly treated with pyrimidine analogs, yet the predictive value of mismatch repair status for response to these agents has not been examined in this malignancy. A tissue microarray with associated clinical outcome, comprising 254 resected pancreatic ductal adenocarcinoma patients was stained for four mismatch repair proteins (MLH1, MSH2, MSH6 and PMS2). Mismatch repair deficiency and proficiency was determined by the absence or presence of uniform nuclear staining in tumor cells, respectively. Cases identified as mismatch repair deficient on the tissue microarray were confirmed by immunohistochemistry on whole slide sections. Of the 265 cases, 78 (29%) received adjuvant treatment with a pyrimidine analog and 41 (15%) showed a mismatch repair-deficient immunoprofile. Multivariable disease-specific survival in the mismatch repair-proficient cohort demonstrated that adjuvant chemotherapy, regional lymph-node status, gender, and the presence of tumor budding were significant independent prognostic variables (P≤0.04); however, none of the eight clinico-pathologic covariates examined in the mismatch repair-deficient cohort were of independent prognostic significance. Univariable assessment of disease-specific survival revealed an almost identical survival profile for both treated and untreated patients with a mismatch repair-deficient profile, while treatment in the mismatch repair-proficient cohort conferred a greater than 10-month median disease-specific survival advantage over their untreated counterparts (P=0.0018). In this cohort, adjuvant chemotherapy with a pyrimidine analog conferred no survival advantage to mismatch repair-deficient pancreatic ductal adenocarcinoma patients. Mismatch repair immunoprofiling is a feasible predictive marker in pancreatic ductal adenocarcinoma patients, and further prospective

    A 63-year-old man with Stage IVa pancreas tail cancer was admitted for a distal pancreatectomy and splenectomy; adjuvant chemotherapy with gemcitabine was also administered. The chemotherapy was terminated after 16 courses due to hemolytic anemia, thrombocytopenia and renal dysfunction. Plasma exchange was performed; however the patient's renal function was diminished, requiring chronic hemodialysis. Physicians should be cautious of hemolytic uremic syndrome as a possible adverse reaction to gemcitabine and be aware that tests are needed for its early detection.

    Background Adjuvant chemotherapy for colon cancer has been linked to patient and provider characteristics but little is known about whether distance to chemotherapy providers constitutes an obstacle to chemotherapy. Methods A total of 1,184 Medicaid patients diagnosed with colon cancer in North Carolina in 1999–2002 comprised the sample. Data from the N.C. Central Cancer Registry, N.C. Medicaid Claims, American Hospital Directory and US Census were merged. Logistic regression models were used to estimate the association between chemotherapy receipt and the distance to nearest chemotherapy provider. Results Compared to the referent group of SEER-staged II (local) cancer patients living less than 2 miles from the nearest chemotherapy provider, the odds of receiving chemotherapy fell as the distance to the nearest provider increased. The odds ratio (OR) for those living ≥5 to <15 miles away was 0.13 [95% confidence intervals (CI), 0.04–0.39], and OR for those living ≥15 miles away was 0.06 (95% CI, 0.01–0.52). Patients diagnosed with regional, SEER-staged III (regional) cancer were less likely to receive chemotherapy if they lived in rural areas more than 20 miles away from the nearest provider (OR =0.08; 95% CI, 0.01–0.72). However, we found no evidence of association between chemotherapy receipt and distance to the nearest provider for regional cancer patients living in urban areas and those living in rural areas within 20 miles from the nearest chemotherapy provider. Conclusions Distance to provider may be an obstacle to chemotherapy for some groups of low-income colon cancer patients. Relieving travel burdens of rural patients living far from providers may help Medicaid increase guideline-consistent adjuvant care for regional cancer patients. PMID:27284464

    Purpose: to evaluate the efficacy of simultaneous postoperative temozolomide radiochemotherapy in glioblastoma patients. Patients and methods: from February 2002 to July 2004, n = 65 patients from 11 German centers with macroscopic complete tumor resection were randomized to receive either postoperative radiotherapy alone (RT, n = 35) or postoperative radiotherapy with simultaneous temozolomide (RT + TMZ, n = 30). Patients were stratified according to age ({<=}/> 50 years) and WHO performance score (0-1 vs. 2). RT consisted of 60 Gy in 30 fractions. In the RT + TMZ arm, oral TMZ was administered daily at a dose of 75 mg/m{sup 2} including weekends (40-42 doses). Adjuvant treatment was not given, but in both arms, patients with recurrent tumors and in good condition (WHO 0-2) were scheduled for salvage chemotherapy with TMZ. Results: the trial was stopped early due to the results of EORTC-study 26981-22981 that showed a survival benefit for the combination of concomitant and adjuvant TMZ compared to radiotherapy alone. In total, 62/65 patients were evaluable. Stratification variables were well balanced ({<=} 50 years 26% vs. 20%, WHO 0-1 91% vs. 100%). Neither overall survival (median 17 vs. 15 months) nor progression-free survival (median 7 vs. 6 months) differed significantly between the two arms. In the RT (RT + TMZ) arm, 76% (62%) of the progressing patients received salvage chemotherapy with TMZ, 36% (50%) had a second resection. There was a time-constant trend for increased general quality of life (EORTC questionnaire QLQ C30) and brain-specific quality of life (EORTC questionnaire B20) in the combined arm. Lymphopenia G3-4 was more frequent (33 vs. 6%) in the RT + TMZ arm. Conclusion: after early closure of this trial, a benefit for progression-free survival for simultaneous TMZ radiochemotherapy alone could not be demonstrated. In both arms, salvage therapies were frequently used and probably had a major effect on overall survival. (orig.)

    Background Squamous cell carcinomas (SCC) account for approximately 30% of non-small cell lung cancer (NSCLC). Current staging methods do not adequately predict outcome for this disease. EMX2 is a homeo-domain containing transcription factor known to regulate a key developmental pathway. This study assessed the significance of EMX2 as a prognostic and predictive marker for resectable lung SCC. Methods Two independent cohorts of patients with lung SCC undergoing surgical resection were studied. EMX2 protein expression was examined by immunohistochemistry, Western blot, or immunofluorescence. EMX2 expression levels in tissue specimens were scored and correlated with patient outcomes. Chemo-sensitivity of lung SCC cell lines stably transfected with EMX2 shRNAs to cisplatin, carboplatin, and docetaxel was examined in vitro. Results EMX2 expression was down-regulated in lung SCC tissue samples compared to their matched adjacent normal tissues. Positive EMX2 expression was significantly associated with improved overall survival in stage I lung SCC patients, and in stage II/IIIA lung SCC patients receiving adjuvant chemotherapy. EMX2 expression was also associated with expression of EMT markers in both lung SCC cell lines and tissue samples. Knock-down of EMX2 expression in lung SCC cells promoted chemo-resistance and cell migration. Conclusions EMX2 expression is down-regulated in lung SCC and its down-regulation is associated with chemo-resistance in lung SCC cells, possibly through regulation of Epithelial-to-Mesenchymal Transition (EMT). EMX2 may serve as a novel prognostic marker for stage I lung SCC patients and a prediction marker for stage II/IIIA lung SCC patients receiving adjuvant chemotherapy. PMID:26132438

    2014-01-01

    Full Text Available Background: Intraperitoneal administration of paclitaxel (PTX can elicit a marked clinical response in peritoneal metastases of gastric cancer. Methods: In this study, we retrospectively analyzed the clinical outcome of 17 patients who underwent R0 resection with D2 dissection for advanced gastric cancer with macroscopic serosal exposure and received intraperitoneal PTX as adjuvant therapy. Results: A pathological study revealed that the depth of invasion of the primary tumor was pT4a or pT4b in 10 cases, and that the pN stage was more than pN2 in 8 cases. Genetic analysis of peritoneal lavage fluid was performed in 14 cases, all of which were positive for carcinoembryonic antigen mRNA. In these patients, PTX was intraperitoneally administered at 20-60 mg/m2 with oral S-1 for 3-36 months after surgery. In a median follow-up period of 66 months, recurrence occurred in the liver and peritoneum in 2 (11.7% and 1 (5.9% patients, respectively, and no nodal recurrence was observed. Five-year overall survival and disease-free survival were 88.2 and 82.3%, respectively. Conclusion: Since these patients are considered to be a high-risk group for peritoneal recurrence, this result strongly suggests that adjuvant chemotherapy including intraperitoneal PTX is a promising protocol to improve the outcome of patients with advanced gastric cancer with serosal exposure.

    Purpose: To investigate the effects of adjuvant chemotherapy in nasopharyngeal carcinoma (NPC) patients with persistently detectable plasma Epstein-Barr virus DNA (pEBV DNA) after curative radiation therapy plus induction/concurrent chemotherapy. Methods and Materials: The study population consisted of 625 NPC patients with available pEBV DNA levels before and after treatment. Eighty-five patients with persistently detectable pEBV DNA after 1 week of completing radiation therapy were eligible for this retrospective study. Of the 85 patients, 33 were administered adjuvant chemotherapy consisting of oral tegafur-uracil (2 capsules twice daily) for 12 months with (n=4) or without (n=29) preceding intravenous chemotherapy of mitomycin-C, epirubicin, and cisplatin. The remaining 52 patients who did not receive adjuvant chemotherapy served as the control group. Results: Baseline patient characteristics at diagnosis (age, sex, pathologic type, performance status, T classification, N classification, and overall stage), as well as previous treatment modality, were comparable in both arms. After a median follow-up of 70 months for surviving patients, 45.5% (15 of 33 patients) with adjuvant chemotherapy and 71.2% (37 of 52 patients) without adjuvant chemotherapy experienced tumor relapses (P=.0323). There were a significant reduction in distant failure (P=.0034) but not in local or regional recurrence. The 5-year overall survival rate was 71.6% for patients with adjuvant chemotherapy and 28.7% for patients without adjuvant chemotherapy (hazard ratio 0.27; 95% confidence interval 0.17-0.55; P<.0001). Conclusions: Our retrospective data showed that adjuvant chemotherapy can reduce distant failure and improve overall survival in NPC patients with persistently detectable pEBV DNA after curative radiation therapy plus induction/concurrent chemotherapy.

However, RNU can result in decreased renal function and cannot be treated with adjuvant chemotherapy. We performed a risk group stratification analysis to determine the preoperative factors that are predictive of diminished renal function after RNU.Materials and methods: We retrospectively evaluated the medical records of all patients who underwent nephroureterectomy for upper urinary tract urothelial carcinoma at the Chang Gung Memorial Hospital from 2001 to 2008. We analyzed the association between perioperative glomerular filtration rate and preoperative parameters including cancer characteristics, serum creatinine level, and kidney size measured on computed tomographic images.Results: A total of 242 patients fulfilled the inclusion criteria. The average decrease in renal function 1 month after RNU was 19.7%. Using 60 mL/min/1.73 m2 as the eligibility cutoff for cisplatin-based chemotherapy, 42.1% of the population was eligible prior to nephroureterectomy, whereas following surgery only 15.2% remained eligible. Using a cutoff of 45 mL/min/1.73 m2, 59.9% of the cohort was eligible for fractionated cisplatin dosing preoperatively, whereas only 32.6% remained above the cutoff postoperatively. The most significant predictors of poor postoperative renal function were body mass index >25 kg/m2, age >65 years, contralateral kidney length less than 10 cm, and absence of ipsilateral hydronephrosis

    Purpose The aim of this study was to examine the antioxidant activity of ginger extract oral supplement in newly diagnosed cancer patients receiving adjuvant chemotherapy compared to placebo. Patients and methods Newly diagnosed cancer patients receiving moderate-to-high emetogenic potential adjuvant chemotherapy were randomized to receive either a ginger extract (standardized 6-gingerol 20 mg/day) or a placebo 3 days prior to chemotherapy, which they continued daily. Oxidant/antioxidant parameters, including the activities of superoxide dismutase (SOD) and catalase (CAT) and levels of glutathione peroxidase (GPx), total glutathione (GSH/GSSG), lipid peroxidation products detected as malondialdehyde (MDA) and NO2−/NO3−, were measured at baseline and at days 1, 22, 43 and 64 after undergoing chemotherapy. Two-sided statistical analysis, with P ginger group and placebo group, respectively. Antioxidant activity parameters, including SOD, CAT, GPx and GSH/GSSG, were significantly increased at day 64 in the ginger group compared to those in the placebo group, while MDA and NO2−/NO3− levels were significantly decreased (P ginger extract started 3 days prior to chemotherapy has been shown to significantly elevate antioxidant activity and reduce oxidative marker levels in patients who received moderate-to-high emetogenic potential chemotherapy compared to placebo.

    Gastric cancer (GC) has a high morbidity worldwide each year especially in China and advanced GC is well known with poor prognosis, for which surgical resection combine adjuvant chemotherapy is the optimal choice for therapy. Leukocyte is an important index during the treatment for its influence on drugs' dosage and tolerance. Therefore, peripheral blood leukocyte and its subsets during adjuvant chemotherapy may have great clinical value for predicting prognostic. In this retrospective study, we showed the distribution of white blood cell and its subsets in the baseline period before adjuvant chemotherapy in 399 patients who underwent radical resection for advanced GC from January 1, 2008 to August 31, 2012. We investigated the relationship between leukocyte count and overall survival (OS) as well as disease-free survival (DFS). In these patients, females were more likely to have less white blood cells after operation (P=0.016). Patients with pre-chemotherapy leukocyte count less than 4×10(9)/L got worse DFS (P=0.028) and OS (P=0.016). In multivariate analysis, tumor size ≥ 6cm (P=0.033), TNM stage IV (P=0.024), vascular or nerval invasion (P=0.005) and leukocyte count less than 4.0×10(9)/L (P=0.019) was associated with poor DFS. TNM stage IV (P=0.008), vascular or nerval invasion (P=0.001) and lower leukocyte count (P=0.045) were independent risk factors for poor OS. Taken together, our findings suggest that pre-adjuvant chemotherapy peripheral blood leukocyte count correlates with clinical outcome of patients with advanced GC after radical resection.

    We report the development of spinal infarction during adjuvant chemotherapy with tegafur, gimeracil and oteracil (TS-1) after surgery for lung adenocarcinoma. A 69-year-old female had a left upper lobectomy for pulmonary adenocarcinoma, T2aN0M0. Six weeks after the surgery, tegafur, gimeracil and oteracil were administered orally as adjuvant chemotherapy for 1 year. After 10 months of adjuvant chemotherapy, the patient suddenly showed signs of numbness and weakness in both lower limbs. The patient did not have a previous medical history, and was receiving only tegafur, gimeracil and oteracil with the stomach medication. Neurological findings showed muscle weakness, numbness and a loss of tendon reflex in both lower limbs, as well as bladder and rectal disturbance. Blood tests, brain magnetic resonance imaging and chest computed tomography showed no signs of abnormalities or metastasis. Magnetic resonance imaging of the spine showed a hyperintense lesion between the Th12 and L1 spinal levels by T2-weighted image. A spinal fluid test indicated no abnormalities, and cytological diagnosis was class II. Anti-aquaporin 4, anti-ganglioside and anti-neuronal autoantibodies were all negative. These results indicated that the patient had a spinal infarction, rather than myelitis or paraneoplastic neurological syndrome. The patient was treated with heparin and steroid pulse treatment followed by rehabilitation, and recovered sufficiently to be able to walk using a cane after 2 months. The development of spinal infarction during anti-cancer chemotherapy has not been previously reported. In this case, an association of spinal infarction with the use of adjuvant chemotherapy was strongly indicated due to the lack of abnormalities in coagulability, atherosclerotic lesions and aortic disease.

    Purpose: To analyze the recent single-institution experience of patients with salivary gland tumors who had undergone adjuvant intensity-modulated radiotherapy (IMRT), with or without concurrent chemotherapy. Patients and Methods: We performed a retrospective analysis of 35 salivary gland carcinoma patients treated primarily at the Dana-Farber Cancer Institute between 2005 and 2010 with surgery and adjuvant IMRT. The primary endpoints were local control, progression-free survival, and overall survival. The secondary endpoints were acute and chronic toxicity. The median follow-up was 2.3 years (interquartile range, 1.2-2.8) among the surviving patients. Results: The histologic types included adenoid cystic carcinoma in 15 (43%), mucoepidermoid carcinoma in 6 (17%), adenocarcinoma in 3 (9%), acinic cell carcinoma in 3 (9%), and other in 8 (23%). The primary sites were the parotid gland in 17 (49%), submandibular glands in 6 (17%), tongue in 4 (11%), palate in 4 (11%), and other in 4 (11%). The median radiation dose was 66 Gy, and 22 patients (63%) received CRT. The most common chemotherapy regimen was carboplatin and paclitaxel (n = 14, 64%). A trend was seen for patients undergoing CRT to have more adverse prognostic factors, including Stage T3-T4 disease (CRT, n = 12, 55% vs. n = 4, 31%, p = .29), nodal positivity (CRT, n = 8, 36% vs. n = 1, 8%, p = .10), and positive margins (n = 13, 59% vs. n = 5, 38%, p = .30). One patient who had undergone CRT developed an in-field recurrence, resulting in an overall actuarial 3-year local control rate of 92%. Five patients (14%) developed distant metastases (1 who had undergone IMRT only and 4 who had undergone CRT). Acute Grade 3 mucositis, esophagitis, and dermatitis occurred in 8%, 8%, and 8% (1 each) of IMRT patients and in 18%, 5%, and 14% (4, 1, and 3 patients) of the CRT group, respectively. No acute Grade 4 toxicity occurred. The most common late toxicity was Grade 1 xerostomia (n = 8, 23%). Conclusions: Treatment of

    Objective: To evaluate the effect of postoperative adjuvant chemotherapy on survival after complete resection of stage Ⅲ-N2 non-small-cell lung cancer. Methods: From Jan. 1999 to Dec. 2003, one-hundred and fifty patients, who were diagnosed as stage Ⅲ-N2 non-small cell lung cancer after operation, were randomly devided into chemotherapy group and control group. The former received four cycles of chemotherapy with NVB (25 mg/m2,D1, D5)/paclitaxel (175 mg/m2, DI) and Carboplatin (AUC=5, D1). Results: In chemotherapy group, 75.8% (68/79) of patients had finished the 4 cycles of chemotherapy and no one died of toxic effects of chemotherapy.Twenty-five percent of the patients had grade 3-4 neutropenia and 2% had febrile neutropenia. The median survival for the entire 150 patients was 879 d, with 1-year survival rate of 81%, 2-year survival rate of 59% and 3-year survival rate of 43%. There was no significant difference in median survival between chemotherapy and control group (897 d vs 821 d, P=0.0527), but there was significant difference in the 1-year and 2-year overall survival (94.71%, 76.28% vs 512 d, P=0.122), but there was significant difference in the 2-year survival rate between two groups with brain metastases (66.7% vs 37.6% P<0.05). The median survival after brain metastasis appeared was 190 days. Conclusion: Postoperative adjuvant chemotherapy does not significantly improve median survival among patients with completely resected stage Ⅱ-N2 non-small-cell lung cancer, but significantly improves the 1-year and 2-year overall survival. It neither decreases the incidence of brain metastasis but put off the time of brain metastasis.

    Purpose: Long-term survival rates for patients with resected pancreatic ductal adenocarcinoma (PDAC) have stagnated at 20% for more than a decade, demonstrating the need to develop novel adjuvant therapies. Gemcitabine-erlotinib therapy has demonstrated a survival benefit for patients with metastatic PDAC. Here we report the first phase 2 study of erlotinib in combination with adjuvant chemoradiation and chemotherapy for resected PDAC. Methods and Materials: Forty-eight patients with resected PDAC received adjuvant erlotinib (100 mg daily) and capecitabine (800 mg/m{sup 2} twice daily Monday-Friday) concurrently with intensity modulated radiation therapy (IMRT), 50.4 Gy over 28 fractions followed by 4 cycles of gemcitabine (1000 mg/m{sup 2} on days 1, 8, and 15 every 28 days) and erlotinib (100 mg daily). The primary endpoint was recurrence-free survival (RFS). Results: The median follow-up time was 18.2 months (interquartile range, 13.8-27.1). Lymph nodes were positive in 85% of patients, and margins were positive in 17%. The median RFS was 15.6 months (95% confidence interval [CI], 13.4-17.9), and the median overall survival (OS) was 24.4 months (95% CI, 18.9-29.7). Multivariate analysis with adjustment for known prognostic factors showed that tumor diameter >3 cm was predictive for inferior RFS (hazard ratio, 4.01; P=.001) and OS (HR, 4.98; P=.02), and the development of dermatitis was associated with improved RFS (HR, 0.27; P=.009). During CRT and post-CRT chemotherapy, the rates of grade 3/4 toxicity were 31%/2% and 35%/8%, respectively. Conclusion: Erlotinib can be safely administered with adjuvant IMRT-based CRT and chemotherapy. The efficacy of this regimen appears comparable to that of existing adjuvant regimens. Radiation Therapy Oncology Group 0848 will ultimately determine whether erlotinib produces a survival benefit in patients with resected pancreatic cancer.

    Full Text Available Background: Combination of radical surgery and radiotherapy is the standard management of head and neck malignancies. But due to considerable morbidity of surgery and associated cosmetic and functional deficiencies, often aggravated by adjuvant radiotherapy, many patients prefer only radiotherapy with its′ decreased chance of survival. Proper surgical facilities are also not accessible to most of our patients. Neo-adjuvant chemotherapy and loco-regional management by surgery and / or radiotherapy have emerged as a viable alternative. Aims: The purpose of this study is to find out the survival outcome as well as toxicity profile of Neo-adjuvant chemotherapy with cisplatin and short infusional (3 hours 5-FU followed by radiotherapy in advanced head and neck malignancies. Materials and Methods: From June 2002 to December 2003, seventy four patients with advanced head and neck malignancies were planned to be treated with Cisplatin (50 mg / sq. meter on Days 1 and 2 and 5 - FU (600 mg / sq. meter on Days 1, 2 and 3 by 3 hour infusion on Day care basis. On completion of four cycles of chemotherapy at 21 days interval, all patients were destined to receive 6000 cGy of radiotherapy to the loco - regional site. Results: At one year follow up on completion of therapy, 57% patients were alive and 31% patients were disease free. These 31% patients enjoyed a good quality of life in terms of cosmetic and functional deficits. Toxicities were moderate and easily manageable. Conclusion: The study indicated that neo-adjuvant chemotherapy with Cisplatin and short infusional 5 - FU may be delivered on day care basis and results are comparable with Cisplatin and 96 hours continuous infusional 5 - FU. Thus avoiding the continuous infusional 5 - FU, 7 to 10 days in-patient hospitalization during each cycle may be avoided which is a constrain in developing countries like us.

    Background Updated practice guidelines on adjuvant chemotherapy for completely resected colon cancer are lacking. In 2008, Cancer Care Ontario’s Program in Evidence-Based Care developed a guideline on adjuvant therapy for stages ii and iii colon cancer. With newer regimens being assessed in this patient population and older agents being either abandoned because of non-effectiveness or replaced by agents that are more efficacious, a full update of the original guideline was undertaken. Methods Literature searches (January 1987 to August 2015) of medline, embase, and the Cochrane Library were conducted; in addition, abstracts from the American Society of Clinical Oncology, the European Society for Medical Oncology, and the European Cancer Congress were reviewed (the latter for January 2007 to August 2015). A practice guideline was drafted that was then scrutinized by internal and external reviewers whose comments were incorporated into the final guideline. Results Twenty-six unique reports of eighteen randomized controlled trials and thirteen unique reports of twelve meta-analyses or pooled analyses were included in the evidence base. The 5 recommendations developed included 3 for stage ii colon cancer and 2 for stage iii colon cancer. Conclusions Patients with completely resected stage iii colon cancer should be offered adjuvant 5-fluorouracil (5fu)–based chemotherapy with or without oxaliplatin (based on definitive data for improvements in survival and disease-free survival). Patients with resected stage ii colon cancer without “high-risk” features should not receive adjuvant chemotherapy. For patients with “high-risk” features, 5fu-based chemotherapy with or without oxaliplatin should be offered, although no clinical trials have been conducted to conclusively demonstrate the same benefits seen in stage iii colon cancer.

    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.

    In the National Comprehensive Cancer Network (NCCN) guidelines, oxaliplatin (L-OHP)-based chemotherapeutic regimens, including 5-fluorouracil, Leucovorin (LV), and L-OHP (FOLFOX); capecitabine and L-OHP (CapeOX); and 5-fluorouracil, folinic acid, and L-OHP (FLOX) are designated as category 1 recommendations for postoperative adjuvant chemotherapy in Stage III colon cancer, followed by capecitabine and 5-fluorouracil plus LV as category 2A recommendations. We studied the selection of drugs for adjuvant chemotherapy and assessed the tolerability and safety of CapeOX and tegafur-uracil (UFT) plus LV (UFT/LV) in patients with Stage III colon cancer. The study group included 104 consecutive patients with Stage III colon cancer who underwent curative surgery. One patient changed hospitals immediately after surgery. Among the remaining 103 patients, 82 (80%) received adjuvant chemotherapy and 21 (20%) did not. CapeOX was administered to 32 patients (31%), UFT/LV to 49 patients (48%), and capecitabine to 1 patient (1%). In 59 patients, the treatment choice was determined according to the patient's preference; 32 patients (54%) selected CapeOX, 26 (44%) selected UFT/LV, and 1 (2%) selected no chemotherapy. The treatment completion rate was 80% for CapeOX and 84% for UFT/LV. Among patients who completed chemotherapy, dose reduction and drug withdrawal were not required in 22% of patients who received CapeOX and 80% of those who received UFT/LV. Neither CapeOX nor UFT/LV was associated with any serious adverse events. The tolerability and safety of CapeOX and UFT/LV were acceptable. However, CapeOX dose had to be carefully adjusted according to each patient's condition.

    We report a novel system of organically modified silica nanoparticles (Ormosil) capable of near infrared fluorescence and chemotherapy with adjuvant hyperthermia for image guided cancer therapy. Ormosil nanoparticles were loaded with a chemotherapeutic, Doxorubicin (DOX) and cyanine dye, IR820. Ormosil particles had a mean diameter of 51.2±2.4 nanometers and surface charge of -40.5±0.8mV. DOX was loaded onto Ormosil particles via physical adsorption (FDSIR820) or covalent linkage (CDSIR820) to the silanol groups on the Ormosil surface. Both formulations retained DOX and IR820 over a period of 2 days in aqueous buffer, though CDSIR820 retained more DOX (93.2%) compared to FDSIR820 (77.0%) nanoparticles. Exposure to near infrared laser triggered DOX release from CDSIR820. Uptake of nanoparticles was determined by deconvolution microscopy in ovarian carcinoma cells (Skov-3). CDSIR820 localized in the cell lysosomes whereas cells incubated with FDSIR820 showed DOX fluorescence from the nucleus indicating leakage of DOX from the nanoparticle matrix. FDSIR820 nanoparticles showed severe toxicity in Skov-3 cells whereas CDSIR820 particles had the same cytotoxicity profile as bare (No DOX and IR820) Ormosil particles. Furthermore, exposure of CDSIR820 nanoparticles to Near Infrared laser at 808 nanometers resulted in generation of heat (to 43°C from 37°C) and resulted in enhanced cell killing compared to Free DOX treatment. Bio-distribution studies showed that CDSIR820 nanoparticles were primarily present in the organs of Reticuloendothelial (RES) system.

    With the increasing use of adjuvant chemotherapy for treating early breast cancer, febrile neutropenia management has become crucial. Guidelines for febrile neutropenia management are mostly based on a Caucasian population survey although ethnic differences are reported in terms of adverse events. We survey the current status of febrile neutropenia and risk factors in Japanese female breast cancer patients receiving neoadjuvant and adjuvant chemotherapy regimens potential for febrile neutropenia. Subsequently, we plan to conduct a multicenter prospective cohort study involving 1000 patients with operable breast cancer. With the current state of oral antibiotics being routinely prescribed without hematology tests, we survey febrile neutropenia based on two different definitions, namely, true febrile neutropenia: ≥37.5°C and Grade 4 neutropenia, and surrogate febrile neutropenia: ≥37.5°C and oral antibiotic and antipyretic intake. The comparison of true febrile neutropenia and surrogate febrile neutropenia incidences is anticipated to provide information on the safety and feasibility of chemotherapy management without performing blood tests.

    Risk of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) post-breast cancer treatment with adjuvant chemotherapy and granulocyte colony-stimulating factors (G-CSF) is not fully characterized. Our objective was to estimate MDS/AML risk associated with specific breast cancer treatments. We conducted a retrospective cohort study of women aged ≥66 years with stage I-III breast cancer between 2001 and 2009 using the Surveillance, Epidemiology, and End Results-Medicare database. Women were classified as receiving treatment with radiation, chemotherapy, and/or G-CSF. We used multivariable Cox proportional hazards models to estimate adjusted hazard ratios (HR) and 95 % confidence intervals (CI) for MDS/AML risk. Among 56,251 breast cancer cases, 1.2 % developed MDS/AML during median follow-up of 3.2 years. 47.1 % of women received radiation and 14.3 % received chemotherapy. Compared to breast cancer cases treated with surgery alone, those treated with chemotherapy (HR = 1.38, 95 %-CI 0.98-1.93) and chemotherapy/radiation (HR = 1.77, 95 %-CI 1.25-2.51) had increased risk of MDS/AML, but not radiation alone (HR = 1.08, 95 % CI 0.86-1.36). Among chemotherapy regimens and G-CSF, MDS/AML risk was differentially associated with anthracycline/cyclophosphamide-containing regimens (HR = 1.86, 95 %-CI 1.33-2.61) and filgrastim (HR = 1.47, 95 %-CI 1.05-2.06), but not pegfilgrastim (HR = 1.10, 95 %-CI 0.73-1.66). We observed increased MDS/AML risk among older breast cancer survivors treated with anthracycline/cyclophosphamide chemotherapy that was enhanced by G-CSF. Although small, this risk warrants consideration when determining adjuvant chemotherapy and neutropenia prophylaxis for breast cancer patients.

    Purpose: To retrospectively analyze results of concurrent chemoradiotherapy (CCRT) using gemcitabine (GEM) for unresectable pancreatic adenocarcinoma. Methods and Materials: Records of 108 patients treated with concurrent external beam radiotherapy (EBRT) and GEM were reviewed. The median dose of EBRT in all 108 patients was 50.4 Gy (range, 3.6-60.8 Gy), usually administered in conventional fractionations (1.8-2 Gy/day). During radiotherapy, most patients received GEM at a dosage of 250 to 350 mg/m{sup 2} intravenously weekly for approximately 6 weeks. After CCRT, 59 patients (54.6%) were treated with adjuvant chemotherapy (AC), mainly with GEM. The median follow-up for all 108 patients was 11.0 months (range, 0.4-37.9 months). Results: Initial responses after CCRT for 85 patients were partial response: 26 patients, no change: 51 patients and progressive disease: 8 patients. Local progression was observed in 35 patients (32.4%), and the 2-year local control (LC) rate in all patients was 41.9%. Patients treated with total doses of 50 Gy or more had significantly more favorable LC rates (2-year LC rate, 42.9%) than patients treated with total doses of less than 50 Gy (2-year LC rate, 29.6%). Regional lymph node recurrence was found in only 1 patient, and none of the 57 patients with clinical N0 disease had regional lymph node recurrence. The 2-year overall survival (OS) rate and the median survival time in all patients were 23.5% and 11.6 months, respectively. Patients treated with AC had significantly more favorable OS rates (2-year OS, 31.8%) than those treated without AC (2-year OS, 12.4%; p < 0.0001). On multivariate analysis, AC use and clinical T stage were significant prognostic factors for OS. Conclusions: CCRT using GEM yields a relatively favorable LC rate for unresectable pancreatic adenocarcinoma, and CCRT with AC conferred a survival benefit compared to CCRT without AC.

    In several, but not all, previous studies, positive p21(WAF1) expression has been suggested as an indicator of a good prognosis in patients with stage III/IV colorectal cancer. However, it is not known whether the same is true for stage B2 patients. The purpose of this study is to assess the influence of p21(WAF1) expression in tumor cells on disease-free survival (DFS) and overall survival (OS) of Astler-Coller stage B2 and C patients with colorectal cancer who underwent 5-fluorouracil-based adjuvant chemotherapy. Nuclear p21(WAF1) was detected by immunohistochemistry in tissue microarrays from 275 colorectal cancers. The expression of p21(WAF1) was associated with DFS (p = 0.025) and OS (p = 0.008) in the subgroup of stage B2 patients that was treated with adjuvant chemotherapy. In multivariate analysis, it remained the only independent prognostic parameter in relation to DFS and OS (p = 0.035 and p = 0.02, respectively). In the subgroup of 72 stage B2 patients with positive p21(WAF1) expression but not in the subgroup of 61 stage B2 patients with negative p21(WAF1) expression, adjuvant chemotherapy was associated with better DFS (85% 5-year survival versus 65% without chemotherapy, p = 0.03) and OS (96% versus 82%, p = 0.014). In the combined stage B2 and C group of patients treated with adjuvant chemotherapy, positive p21(WAF1) expression was also associated with better DFS and OS (p = 0.03, p = 0.002, respectively). Expression of p21(WAF1) in colorectal tumor cells identifies a subgroup of Astler-Coller stage B2 patients who could benefit significantly from 5FU-based chemotherapy and may improve the selection of patients for adjuvant chemotherapy.

    Full Text Available This study aims to evaluate the efficacy and safety of goserelin combined with chemotherapy for premenopausal women with breast cancer. Literatures were extracted from databases including Excerpta Medica Database, Springer, Pubmed, China National Knowledge Infrastructure and Chinese Biological Medicine from their inception up to May 2014. The main efficacy measures were 5 years overall survival (OS, 10 years OS, 5 years disease free survival and 5 years progress free survival. Ten randomized comparison clinical trials were eligible in this study. The result showed that goserelin combined with chemotherapy group can improve the survival rate and decrease the incidence of arthralgia in postmenopausal breast cancer patients, respectively, compared to the control group. However, they can increase the occurrence of vomiting during the chemotherapy process. Compared with the simple chemotherapy, goserelin combined with chemotherapy can provide benefits for premenopausal women with breast cancer on improving the survival rate and reducing arthralgia.

    Objective The aim of the present study was to investigate the ef ect of dendritic cel (DC)/cytokine-in-duced kil er cel (CIK) immunobiological cancer therapy in patients with triple-negative breast cancer (TNBC) who underwent adjuvant chemotherapy. Methods From January 2010 to October 2013, 120 patients with postoperative TNBC were recruited and included in the study. Patients were enrol ed in one of two groups according to whether they accepted DC/CIK immunobiological cancer therapy during adjuvant chemotherapy; the patients in the DC/CIK group underwent adjuvant chemotherapy combined with DC/CIK immunobiological cancer therapy, and the control group underwent adjuvant chemotherapy alone. When six cycles of adjuvant chemotherapy and six cycles of DC/CIK immunobiological cancer therapy had been completed, dif erences between the two groups with regard to quality of life (QoL), immunological indicators (CD3, CD4, CD8, and NK cel levels), disease-free survival (DFS), and side ef ects of chemotherapy and DC/CIK treatment were evaluated. Results In the DC/CIK group, the proportion of NK cel s and CD3+ and CD4+ T-cel subgroups significantly increased, and the proportion of CD8+ cel s decreased when they were compared before and after DC/CIK therapy (P Conclusion The DC/CIK treatment had potential benefits for patients with TNBC compared with the con-trol group, and was not associated with any obvious side ef ects. Therefore, DC/CIK therapy is a safe and ef ective method for the treatment of TNBC.

    For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cel tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrol ed in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P=0.042), and the 3-year overal survival rates were 90.5%and 100%, respectively (P=0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cel tumors.

    AIM: To evaluate the effect of chemotherapy to the acute toxicity of a hypofractionated radiotherapy (HFRT) schedule for breast cancer. METHODS: We retrospectively analyzed 116 breast cancer patients with T1, 2N0Mx. The patients received 3-D conformal radiotherapy with a total physical dose of 50.54 Gy or 53.2 Gy in 19 or 20 fractions according to stage, over 23-24 d. The last three to four fractions were delivered as a sequential tumor boost. All patients were monitored for acute skin toxicity according to the European Organization for Research and Treatment of Cancer/Radiation Therapy Oncology Group criteria. The maximum monitored value was taken as the final grading score. Multivariate analysis was performed for the contribution of age, chemotherapy and 19 vs 20 fractions to the radiation acute skin toxicity. RESULTS: The acute radiation induced skin toxicity was as following: grade I 27.6%, grade II 7.8% and grade III 2.6%. No significant correlation was noted between toxicity grading and chemotherapy (P = 0.154, χ2 test). The mean values of acute toxicity score in terms of chemotherapy or not, were 0.64 and 0.46 respectively (P = 0.109, Mann Whitney test). No significant correlation was also noted between acute skin toxicity and radiotherapy fractions (P = 0.47, χ2 test). According to univariate analysis, only chemotherapy contributed significantly to the development of acute skin toxicity but with a critical value of P = 0.05. However, in multivariate analysis, chemotherapy lost its statistical significance. None of the patients during the 2-years of follow-up presented any locoregional relapse. CONCLUSION: There is no clear evidence that chemotherapy has an impact to acute skin toxicity after an HFRT schedule. A randomized trial is needed for definite conclusions. PMID:25405195

    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

    The aim of the present study was to analyze the effect of subtype and body mass index (BMI) on neo-adjuvant chemotherapy (NAC) and postoperative prognosis. Two-hundred and forty nine patients who underwent surgery after NAC were included. A multivariate analysis and survival analysis were used to clarify the relationship between BMI, subtype, and NAC. In the logistic regression model, the pCR rate had a significant relationship with the subtype and tumor stage. In the non-pCR group, more overweight patients had significantly a worse disease-free survival (DFS) compared to normal range patients (Log lank test, p < 0.05). In the Cox proportional hazards model, subtype and tumor stage were significantly associated with decreased DFS. In conclusion, patients with the ER (+), HER (-) type and a high BMI had a high risk for recurrence when they achieved non-pCR after NAC.

Short- (6 months and long- (12 months term follow-up data from these patients were compared with the retrospective data from an urban cancer centre, where standard protocol of concurrent chemo-radiotherapy is practiced. Materials and Methods: Two hundred patients of advanced cervical cancer, treated at our rural cancer centre between January 2007 and December 2007, were included in the study arm (Group A. These patients received three cycles of neo-adjuvant chemotherapy with Cisplatin, Bleomycin, and Vincristine before External-Beam Radiotherapy (EBT followed by brachytherapy. Patients in the control arm (Group B of an urban cancer centre, received EBT with weekly concomitant Cisplatin, followed by brachytherapy. Short- (6 months and long- (12 months term follow-up data from our patients were compared with the retrospective data from the urban cancer centre. Results and Analysis: Complete response rate was comparatively higher among patients of Group A, also correspondingly proportion of patients showing progressive disease and stable disease was lower among them. Local treatment failure was 87.5% among patients from Group A and 94.4% in Group B patients. Concomitant chemoradiation (CRT was associated with more GI toxicities. Conclusion: Our result suggests NACT arm is as effective as CRT arm in respect of complete response with less pelvic failure and G.I toxicities. Further follow-up data are needed before arriving at a definite conclusion.

    Full Text Available Abstract Background This study examined the association between overall survival and Glutathione S-transferase Pi (GST Pi expression and genetic polymorphism in stage C colon cancer patients after resection alone versus resection plus 5-fluourouracil-based adjuvant chemotherapy. Methods Patients were drawn from a hospital registry of colorectal cancer resections. Those receiving chemotherapy after it was introduced in 1992 were compared with an age and sex matched control group from the preceding period. GST Pi expression was assessed by immunohistochemistry. Overall survival was analysed by the Kaplan-Meier method and Cox regression. Results From an initial 104 patients treated with chemotherapy and 104 matched controls, 26 were excluded because of non-informative immunohistochemistry, leaving 95 in the treated group and 87 controls. Survival did not differ significantly among patients with low GST Pi who did or did not receive chemotherapy and those with high GST Pi who received chemotherapy (lowest pair-wise p = 0.11 whereas patients with high GST Pi who did not receive chemotherapy experienced markedly poorer survival than any of the other three groups (all pair-wise p Conclusion Stage C colon cancer patients with low GST Pi did not benefit from 5-fluourouracil-based adjuvant chemotherapy whereas those with high GST Pi did.

    Neo-adjuvant chemotherapy (NAC) is used to facilitate radical surgery for initially irresectable or locally advanced breast cancer. The indication for NAC has been extended to clinically node negative (cN0) patients in whom adjuvant systemic therapy is foreseen. A population-based study was conducted to evaluate the increasing use of NAC, breast conserving surgery (BCS) after NAC and timing of the sentinel node biopsy (SNB). All female breast cancer patients, treated in 10 hospitals in the Eindhoven Cancer Registry area in the Netherlands between January 2003 and June 2012 were included (N = 18,427). In total, 1,402 patients (7.6%) received NAC. The administration increased from 2.5% in 2003 to 13.0% in 2011 (p 20% (p < 0.001). Of the 1,402 patients with NAC, 495 patients underwent SNB, 91.5% of whom prior to NAC. In the Netherlands up to one in eight patients receive NAC. The administration of NAC and the percentage of BCS increased over the past decade, especially in cT2 tumors. Considerable hospital variation in the administration of NAC exists.

    Background Adjuvant chemotherapy for colorectal cancer is mainly based on the combination of 5-fluorouracil, folinic acid and oxaliplatin (FOLFOX-4). The pharmacological target of oxaliplatin remains intracellular and therefore dependent on its entry into cells. The intracellular distribution of oxaliplatin is mediated by organic cation transporters 1, 2 and 3 (OCT1, 2 and 3), copper transporter 1 (CTR1) and ATPase Cu2+ transporting beta polypeptide (ATP7B) and may modulate the efficacy of oxaliplatin-based chemotherapy. The aim of this study was to perform a retrospective study to assess the relation between the expression of oxaliplatin transporters in colorectal cancer before chemotherapy and the response to FOLFOX-4 adjuvant chemotherapy in responder and non-responder patients. Methods This retrospective study was conducted at a single center (University Hospital of Clermont-Ferrand, France). The target population was patients with resectable colorectal cancer operated between 2006 and 2013. Inclusion criteria were defined for the responder patients as no cancer recurrence 3 years after the end of chemotherapy, and for the non-responder patients as cancer recurrence within 1 year. Other inclusion criteria were stages IIb–IV cancers, first-line adjuvant FOLFOX-4 chemotherapy, and the availability of resected primary tumor samples. Exclusion criteria were preoperative chemotherapy and/or radiotherapy, a targeted therapy, other anticancer drugs, cancer recurrence between the first and the third year after the end of chemotherapy and follow-up < 3 years. Immunostaining of oxaliplatin transporters (OCT1, 2, 3, CTR1 and ATP7B) and Ki-67 was assessed in tumor samples. Results Retrospectively, 31 patients have been selected according to inclusion and exclusion criteria (15 responders and 16 non-responders). Before FOLFOX-4 regimen, OCT3 expression was significantly lower in responder patients compared to non-responders (p<0.001). According to multivariate analysis

    Breast-conserving treatment (BCT) has been validated for breast cancer patients receiving adjuvant chemotherapy. Our objective was to evaluate the difference in loco-regional recurrence (LRR) rates between BCT and mastectomy in patients receiving radiation therapy after neo-adjuvant chemotherapy (NCT). A retrospective data base was used to identify all patients with breast cancer undergoing NCT from 2002 to 2007. Patients with initial metastatic disease were excluded from this analysis. LRR was compared between those undergoing BCT and mastectomy. Individual variables associated with LRR were evaluated. Two hundred eighty-four patients were included, 111 (39%) underwent BCT and 173 (61%) mastectomy. Almost all patients (99%) in both groups received postoperative radiation. Pathologic complete response was seen in 37 patients, of which 28 underwent BCT (p loco-regional control rate was 91% (95% CI: 86-94%). The 10-year LRR rate was similar in the BCT group (9.2% [95% CI: 4.9-16.7%]) and in the mastectomy group (10.7% [95% CI: 5.9-15.2%]; p = 0.8). Ten-year overall survival (OS) rates (63% [95% CI: 46-79%] in the BCT group; 60% [95% CI: 47-73%] in the mastectomy group, p = 0.8) were not statistically different between the two patient populations. Multivariate analysis showed that AJCC stage ≥ III (HR: 2.6; 95% CI: 1.2-5.8; p = 0.02), negative PR (HR: 6; 95% CI: 1.2-30.6, p = 0.03), and number of positive lymph nodes ≥3 (HR: 2.5; 95% CI: 1.1-5.9; p = 0.03) were independent predictors of LRR. Ten-year OS was similar in the BCT and in the mastectomy group (p = 0.1). The rate of LRR was low and did not significantly differ between the BCT and the mastectomy group after NCT. Randomized trials assessing whether mastectomy can be safely omitted in selected breast cancer patients (nonstage III tumors or those which do not require adjuvant hormone suppression) which respond to NCT are required.

    The present study aimed to define high-risk patients who may benefit from additional adjuvant chemotherapy (AC) after concurrent chemotherapy in combination with intensity-modulated radiotherapy among patients with loco-regionally advanced nasopharyngeal carcinoma (NPC). A cohort of 511 NPC patients who received concomitant chemoradiotherapy (CCRT) with or without AC between January 2007 and December 2012 were retrospectively analysed. One hundred seventy-seven patients received CCRT alone, whereas 334 received CCRT + AC. The survival analysis showed that ages >45 years old, T3-T4 stages, N2-N3 disease and serum albumin levels ≤42 g/L were significant independent prognostic factors for overall survival (OS). Using these four risk factors, a prognostic model for OS was created as follows: (1) low-risk group: 0–1 risk factors; and (2) high-risk group: 2–4 risk factors. In the CCRT alone and CCRT + AC groups, significant differences in survival were found between the high- and low-risk groups. Patients in the high-risk group exhibited improved OS due to the addition of AC to CCRT, but no survival benefits were found in the low-risk group. In conclusion, high-risk patients may benefit from the addition of AC to CCRT regarding OS. PMID:28150694

    Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with radiotherapy only at sites distant from the ovaries (chest wall, thigh, and leg) had minimal menstrual irregularities or temporary cessation of menses during therapy; cyclic menses returned promptly after therapy. Gonadotropin levels (expressed as means +/- SD (follicle-stimulating hormone (FSH), 10 +/- 5 mlU/ml; luteinizing hormone (LH), 10 +/- 4 mlU/ml) and 17 beta-estradiol (E2) levels (means +/- SD, 208 +/- 147 pg/ml) were normal. By contrast, 4 older women (ages 36-43 yr) who received similar treatment developed persistent amenorrhea with postmenopausal levels of gonadotropin (FSH, 108 +/- 29 mlU/ml; LH, 72 +/- 19 mlU/ml) and E2 (19 +/- 8 pg/ml). Two additional women (ages 21 and 39 yr) who received radiation (7,000 rad) to the pelvis plus chemotherapy developed prompt cessation of menses and became functional castrates (FSH, 77 and 80 mlU/ml; LH, 40 and 58 mlU/ml; E2, 10 and 19 pg/ml). However, this result would be expected from the radiation dose alone. The data demonstrated that ovarian dysfunction may follow the use of doxorubicin, cyclophosphamide, and high doses of methotrexate and that the injury is age related.

  5. Efficacy of Rasayana Avaleha as adjuvant to radiotherapy and chemotherapy in reducing adverse effects

    OpenAIRE

    2010-01-01

    Cancer is the most dreadful disease affecting mankind. The available treatments such as chemotherapy and radiotherapy have cytotoxic effects, which are hazardous to the normal cells of the patient, causing many unnecessary effects. This further leads to complications of the therapy, impaired health, and deterioration of quality of life, resulting in mandatory stoppage of the treatment. In the present study, the efficacy of an Ayurvedic formulation, Rasayana Avaleha, has been evaluated as an a...

    The treatment of patients with colorectal liver metastasis has improved significantly and first line therapy is often combined chemotherapy and bevacizumab, although it is unknown who responds to this regimen. Colorectal liver metastases grow in different histological growth patterns showing differences in angiogenesis. To identify possible response markers, histological markers of angiogenesis were assessed. Patients who underwent resection of colorectal liver metastasis at Rigshospitalet, Copenhagen, Denmark from 2007 to 2011 were included (n = 254) including untreated and patients treated with chemotherapy or chemotherapy plus bevacizumab. The resected liver metastases were characterised with respect to growth pattern, endothelial and tumour cell proliferation as well as microvessel density and tumour regression. Tumour regression grade of liver metastases differed significantly between untreated/chemotherapy treated patients in comparison to chemotherapy plus bevacizumab treated patients (both p chemotherapy-treated patients (p = 0.006/p = 0.002). Tumour cell proliferation assessed by Ki67 expression correlated to a shorter recurrence free survival in the total patient cohort. In conclusion, liver metastases from patients treated with neo-adjuvant chemotherapy and bevacizumab had significantly lower microvessel densities and tumour regression grades when compared to liver metastases from untreated or chemotherapy treated patients. This may indicate that bevacizumab treatment results in altered vascular biology and tumour viability, with possible tumour reducing effect.

    Full Text Available 'Taste' changes are commonly reported during chemotherapy. It is unclear to what extent this relates to actual changes in taste function or to changes in appetite and food liking and how these changes affect dietary intake and nutritional status.This prospective, repeated measures cohort study recruited participants from three oncology clinics. Women (n = 52 prescribed adjuvant chemotherapy underwent standardised testing of taste perception, appetite and food liking at six time points to measure change from baseline. Associations between taste and hedonic changes and nutritional outcomes were examined.Taste function was significantly reduced early in chemotherapy cycles (p<0.05 but showed recovery by late in the cycle. Ability to correctly identify salty, sour and umami tastants was reduced. Liking of sweet food decreased early and mid-cycle (p<0.01 but not late cycle. Liking of savory food was not significantly affected. Appetite decreased early in the cycle (p<0.001. Reduced taste function was associated with lowest kilojoule intake (r = 0.31; p = 0.008 as was appetite loss with reduced kilojoule (r = 0.34; p = 0.002 and protein intake (r = 0.36; p = 0.001 early in the third chemotherapy cycle. Decreased appetite early in the third and final chemotherapy cycles was associated with a decline in BMI (p = <0.0005 over the study period. Resolution of taste function, food liking and appetite was observed 8 weeks after chemotherapy completion. There was no association between taste change and dry mouth, oral mucositis or nausea.The results reveal, for the first time, the cyclical yet transient effects of adjuvant chemotherapy on taste function and the link between taste and hedonic changes, dietary intake and nutritional outcomes. The results should be used to inform reliable pre-chemotherapy education.

    Ovarian function was evaluated in 11 women 16 to 43 years of age at treatment who received doxorubicin, cyclophosphamide, and high doses of methotrexate with or without radiotherapy in adjuvant therapy of soft tissue sarcoma. Five women (16-33 yr old) who received chemotherapy alone or combined with radiotherapy only at sites distant from the ovaries (chest wall, thigh, and leg) had minimal menstrual irregularities or temporary cessation of menses during therapy; cyclic menses returned promptly after therapy. Gonadotropin levels (expressed as means +/- SD) (follicle-stimulating hormone (FSH), 10 +/- 15 mlU/ml; luteinizing hormone (LH), 10 +/- 4 mlU/ml) and 17 ..beta..-estradiol (E/sub 2/) levels (means +/- SD, 208 +/- 147 pg/ml) were normal. By contrast, 4 older women (ages 36-43 yr) who received similar treatment developd persistent amenorrhea with postmenopausal levels of gonadotropin (FSH, 109 +/- 29 mlU/ml; LH, 72 +/- 19 mlU/ml) and E/sub 2/ (19 +/- 8 pg/ml). Two additional women (ages 21 and 39 yr) who received radiation (7000 rad) to the pelvis plus chemotherapy developed prompt cessation of menses and became functional castrates (FSH, 77 and 80mlU/ml; LH, 40 and 58 mlU/ml; E/sub 2/, 10 and 19 pg/ml). However, this result would be expected from the radiation dose alone. The data demonstrated that ovarian dysfunction may follow the use of doxorubicin, cyclophosphamide, and high doses of methotrexate and that the injury is age related.

    The advent of sentinel lymph node biopsy has revolutionised surgical management of axillary nodal disease in patients with breast cancer. Patients undergoing neo-adjuvant chemotherapy for large breast primary tumours may experience complete pathological response on a previously positive sentinel node whilst not eliminating the tumour from the other lymph nodes. Results from 2 large prospective cohort studies investigating sentinel lymph node biopsy after neo-adjuvant chemotherapy demonstrate a combined false negative rate of 12.6-14.2% and identification rate of 80-89% with the minimal acceptable false negative rate and identification rate being set at 10% and 90%, respectively. A false negative rate of 14% would have been classified as unacceptable when compared to the figures obtained by the pioneers of sentinel lymph node biopsy which was 5% or less.

    Most prolactin-secreting pituitary adenomas demonstrate slow growth and are effectively managed with medical/surgical therapy. Rarely, these tumors can behave aggressively with rapid growth and invasion of local tissues, and are refractory to medical, surgical, or radio-surgical therapies. We report a case of a prolactin-secreting adenoma in a young woman, which became progressively aggressive and refractory to usual treatment modalities, but responded to treatment with the chemotherapeutic agent temozolomide. In addition, we review the literature for treatment of refractory adenomas with temozolomide. The clinical and pathologic characteristics of aggressive prolactin-secreting adenomas are reviewed, as well as their response to dopamine agonists, surgery, radiotherapy, and chemotherapy.

    Full Text Available Abstract Background Since the definition of different histologic subtypes of urothelial carcinomas by the World Health Organization (WHO 2004 classification, description of molecular features and clinical behavior of these variants has gained more attention. Methods We reviewed 205 tumor samples of patients with locally advanced bladder cancer mainly treated within the randomized AUO-AB05/95 trial with radical cystectomy and adjuvant cisplatin-based chemotherapy for histologic subtypes. 178 UC, 18 plasmacytoid (PUC and 9 micropapillary (MPC carcinomas of the bladder were identified. Kaplan Meier analysis and backward multivariate Cox’s proportional hazards regression analysis were performed to compare overall survival between the three histologic subtypes. Results Patients suffering from PUC have the worst clinical outcome regarding overall survival compared to conventional UC and MPC of the bladder that in turn seem have to best clinical outcome (27.4 months, 62.6 months, and 64.2 months, respectively; p=0.013 by Kaplan Meier analysis. Backward multivariate Cox´s proportional hazards regression analysis (adjusted to relevant clinicopathological parameters showed a hazard ratio of 3.2 (p=0.045 for PUC in contrast to patients suffering from MPC. Conclusions Histopathological diagnosis of rare variants of urothelial carcinoma can identify patients with poor prognosis.

    Full Text Available Abstract Bckground A number of studies have investigated whether the activity levels of enzymes involved in 5-fluorouracil (5-FU metabolism are prognostic factors for survival in patients with colorectal carcinoma. Most reports have examined thymidylate synthetase (TS and dihydropyrimidine dehydrogenase (DPD in unresectable or metastatic cases, therefore it is unclear whether the activity of these enzymes is of prognostic value in colorectal cancer patients treated with radical resection and adjuvant chemotherapy with 5-FU. Methods This study examined fresh frozen specimens of colorectal carcinoma from 40 patients who had undergone curative operation and were orally administered adjuvant tegafur/uracil (UFT chemotherapy. TS, DPD and orotate phosphoribosyl transferase (OPRT activities were assayed in cancer tissue and adjacent normal tissue and their association with clinicopathological variables was investigated. In addition, the relationships between TS, DPD and OPRT activities and patient survival were examined to determine whether any of these enzymes could be useful prognostic factors. Results While there was no clear relationship between pathological findings and TS or DPD activity, OPRT activity was significantly lower in tumors with lymph node metastasis than in tumors lacking lymph node metastasis. Postoperative survival was significantly better in the groups with low TS activity and/or high OPRT activity. Conclusion TS and OPRT activity levels in tumor tissue may be important prognostic factors for survival in Dukes' B and C colorectal carcinoma with radical resection and adjuvant chemotherapy with UFT.

    Full Text Available Abstract Background Hyperthermic chemotherapy applies thermal energy to both abdominal wall as well as the intra-abdominal viscera. The combination of the hyperthemia, chemotherapy and cytoreductive surgery (CRS is associated with a defined risk of abdominal wall and intestinal morbidity reported to be as high as 15%, respectively to date, no studies have evaluated the use of biomaterial mesh as adjuvant to abdominal wall closure in this group of patients. In the present report, we hypothesized that post HIPEC closure with a biomaterial can reduce abdominal wall morbidity after CRS and hyperthermic intraperitoneal chemotherapy. Materials and methods All patients treated with HIPEC in a tertiary care center over 12 months (2008-2009 period were included. Eight patients received cytoreductive surgery followed by HIPEC for 90 minutes using Mitomycin C (15 mg q 45 minutes × 2. Abdominal wall closure was performed using Surgisis (Cook Biotech. mesh in an underlay position with 3 cm fascial overlap-closure. Operative time, hospital length of stay (LOS as well as postoperative outcome with special attention to abdominal wall and bowel morbidity were assessed. Results Eight patients, mean age 59.7 ys (36-80 were treated according to the above protocol. The primary pathology was appendiceal mucinous adenocarcinoma (n = 3 colorectal cancer (n = 3, and ovarian cancer (n = 2. Four patients (50% presented initially with abdominal wall morbidity including incisional ventral hernia (n = 3 and excessive abdominal wall metastatic implants (n = 1.

    Full Text Available Purpose: The aim of this study was to compare the accuracy of magnetic resonance imaging (MRI for the prediction of response to neo-adjuvant chemotherapy in triple negative (TN breast cancer, with respect to other subtypes. Materials and Methods: There were a total of 1610 breast cancers diagnosed between March 2009 and August 2014, out of which 82 patients underwent MRI before and after neo-adjuvant chemotherapy but just before surgery. TN cancers were analyzed with respect to others subtypes. Accuracy of MRI for prediction of pathological complete response was compared between different subtypes by obtaining receiver operating characteristic (ROC curves. The Statistical Package for the Social Sciences version 21 was used for all data analysis, with P value of 0.05 as statistically significant. Results: Out of 82 patients, 29 were luminal (HR+/HER2−, 23 were TN (HR−, HER2−, 11 were HER2 positive (HR−, HER2+, and 19 were of hybrid subtype (HR+/HER2+. TN cancers presented as masses on the pre-chemotherapy MRI scan, were grade 3 on histopathology, and showed concentric shrinkage following chemotherapy. TN cancers were more likely to have both imaging and pathological complete response following chemotherapy (P = 0.055 in contrast to luminal cancers, which show residual cancer. ROC curves were constructed for the prediction of pathological complete response with MRI. For the TN subgroup, MR had a sensitivity of 0.745 and specificity of 0.700 (P = 0.035, with an area under curve of 0.745 (95% confidence interval: 0.526–0.965, which was significantly better compared to other subtypes. Conclusion: TN breast cancers present as masses and show concentric shrinkage following chemotherapy. MRI is most accurate in predicting response to chemotherapy in the TN group, compared to others subtypes. MRI underestimates residual disease in luminal cancers.

    Purpose: Analysis of the feasibility and results of adjuvant chemotherapy followed by conformal chemoradiotherapy after surgery for gastric carcinoma. Patients and methods Twenty-six patients (R0 or R1) were treated postoperatively by three cycles of 5-fluorouracil (5-FU) and cisplatin, followed by a concomitant association of LV5FU2 chemotherapy with a conformal radiotherapy of 45 Gy. Results: The tumor was classified pT3-T4 in 77% of the patients and 92.5% had a nodal involvement (pN1: 54%; pN2: 31%). Feasibility (1) Adjuvant chemotherapy: nausea/vomiting grade II/III: 12 patients (48%); neutropenia grade III/IV: two patients; completed in all patients, except one. (2) Chemoradiotherapy: nausea/vomiting grade II/III: 10 patients; diarrhea grade II/3: two patients; oesophagitis grade II/III: two patients; myocardial infarction/pulmonary embolism: two patients. All patients except one received the planned dose of 45 Gy. Radiotherapy was interrupted in six cases, with a median duration of 14 days. Survival: with a median follow-up of 30 months, 65% of the patients were alive without disease; median survival was 32 months. Conclusion: This postoperative schedule was judged feasible. It allowed the deliverance of a more intensified chemotherapy than the classical schedule. Its clinical benefit must be evaluated in a phase III trial. (authors)

    In Japan, the history of postoperative chemotherapy for breast cancer started with 5-fluorouracil (5-FU), launched in the 1980s. Currently, oral fluoropyrimidine-based regimens indicated for the treatment of breast cancer in Japan include tegafur plus uracil (UFT); tegafur, gimeracil, and oteracil (TS-1); doxifluridine; and capecitabine. In particular, UFT represents an important option for long-term treatment because of minimal adverse events and the potential for long-term maintenance of effective plasma concentrations of 5-FU to inhibit micrometastasis after surgery. Therefore, various clinical studies of postoperative adjuvant chemotherapy with UFT have been conducted in patients with completely resected tumors. Recent studies have shown that UFT prolongs survival after tumor resection in patients with gastric cancer, colorectal cancer, and lung cancer. In patients with breast cancer, large clinical trials of UFT-based postoperative chemotherapy conducted in Japan have shown that UFT is useful for the treatment of intermediate-risk patients with no lymph node metastasis. This paper reviews the results of clinical studies of UFT conducted in Japan to assess the therapeutic usefulness of this oral 5-FU. The types of patients most likely to benefit from UFT are discussed on the basis of currently available evidence and a global consensus of treatment recommendations. The optimal timing of endocrine therapy and strategies for postoperative adjuvant chemotherapy with UFT in patients with breast cancer are also discussed.

    Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of cancer therapy. This study evaluates symptoms of CIPN and CIPN-related pain and its influence on psychological functioning and potential predictors of chronic CIPN and pain. In this large prospective questionnaire study, 174 patients receiving adjuvant oxaliplatin or docetaxel were consecutively included. Patients were asked to complete a questionnaire with validated questions on peripheral neuropathy, pain, anxiety and depression, and quality of life at baseline, after the first cycle, halfway through therapy, and 1 year after baseline. Chronic CIPN symptoms (tingling and/or numbness) in the feet at 1-year follow-up were present in 63.6% of patients without preexisting neuropathy in the oxaliplatin group and in 44.8% in the docetaxel group, whereas pain in hands and feet was found in 31.3% and 35.1%, respectively. Both groups had significantly different pain profiles, and persistent pain in the docetaxel group was found to have effect on psychological function. Cumulative dose predicted oxaliplatin-induced neuropathy (P = 0.004), whereas endocrine therapy predicted peripheral pain in the docetaxel group (P = 0.04). There are important differences in acute neuropathic symptoms and chronic pain profiles in patients after oxaliplatin and docetaxel treatment. It is, however, important to recognize that chronic peripheral pain may be unrelated to neuropathy and can be caused by concomitant treatments. Future studies should focus on characterizing and distinguishing CIPN-related pain from other types of pain to determine the best outcome measures for trials on prevention or relief.

  20. Is drug-induced toxicity a good predictor of response to neo-adjuvant chemotherapy in patients with breast cancer? -A prospective clinical study

    2004-08-01

    Full Text Available Abstract Background Neo-adjuvant chemotherapy is an integral part of multi-modality approach in the management of locally advanced breast cancer and it is vital to predict the response in order to tailor the regime for a patient. The common final pathway in the tumor cell death is believed to be apoptosis or programmed cell death and chemotherapeutic drugs like other DNA-damaging agents act on rapidly multiplying cells including both the tumor and the normal cells by following the same common final pathway. This could account for both the toxic effects and the response. Absence or decreased apoptosis has been found to be associated with chemo resistance. The change in expression of apoptotic markers (Bcl-2 and Bax proteins brought about by various chemotherapeutic regimens is being used to identify drug resistance in the tumor cells. A prospective clinical study was conducted to assess whether chemotherapy induced toxic effects could serve as reliable predictors of apoptosis or response to neo-adjuvant chemotherapy in patients with locally advanced breast cancer. Methods 50 cases of locally advanced breast cancer after complete routine and metastatic work up were subjected to trucut biopsy and the tissue evaluated immunohistochemically for apoptotic markers (bcl-2/bax ratio. Three cycles of Neoadjuvant Chemotherapy using FAC regime (5-fluorouracil, adriamycin, cyclophosphamide were given at three weekly intervals and patients assessed for clinical response as well as toxicity after each cycle. Modified radical mastectomy was performed in all patients three weeks after the last cycle and the specimen were re-evaluated for any change in the bcl-2/bax ratio. The clinical response, immunohistochemical response and the drug-induced toxicity were correlated and compared. Descriptive studies were performed with SPSS version 10 and the significance of response was assessed using paired t-test. Significance of correlation between various variables was

    Delayed gastric emptying symptoms are often reported after chemotherapy. This study aims to characterise the effects of chemotherapy on gastric neuro-muscular function. Patients undergoing elective surgery for oesophago-gastric cancer were recruited. Acetylcholinesterase, nNOS, ghrelin receptor and motilin expressions were studied in gastric sections from patients receiving no chemotherapy (n = 3) or oesophageal (n = 2) or gastric (n = 2) chemotherapy. A scoring system quantified staining intensity (0-3; no staining to strong). Stomach sections were separately suspended in tissue baths for electrical field stimulation (EFS) and exposure to erythromycin or carbachol; three patients had no chemotherapy; four completed cisplatin-based chemotherapy within 6 weeks prior to surgery. AChE expression was markedly decreased after chemotherapy (scores 2.3 ± 0.7, 0.5 ± 0.2 and 0 ± 0 in non-chemotherapy, oesophageal- and gastric-chemotherapy groups (p gastric function.

    Desmoplastic small round cell tumor (DSRCT) is a rare,highly aggressive malignancy with distinctive histological features: a nesting pattern of cellular growth within dense desmoplastic stroma, occurring in young population with male predominance. The mean survival period is only about 1.5-2.5 years. The tumor has co-expressed epithelial, muscle, and neural markers in immunohistochemical studies. This work reports a 27-year-old man presenting with hematemesis and chronic constipation.Serial studies including endoscopy, upper gastrointestinal series, abdominal computed tomography and barium enema study showed disseminated involvement of visceral organs. The patient underwent aggressive surgery and received postoperative adjuvant chemotherapy consisting of 5-fluorouracil, cyclophosphamide,etoposide, doxorubicin, and cisplatin. He survived without any disease for 20 mo after the surgery. No standard treatment protocol has been established. Aggressive surgery combined with postoperative multi-agent adjuvant chemotherapy is justified not only to relieve symptoms but also to try to improve the outcome in this advanced DSRCT young patient.

    Background Triple-negative breast cancer (TNBC) is a heterogeneous tumor that encompasses many different subclasses of the disease. In this study, we assessed BRCAness, defined as the shared characteristics between sporadic and BRCA1-mutated tumors, in a large cohort of TNBC cases. Methods The BRCAness of 262 patients with primary TNBCs resected between January 2004 and December 2014 was determined through the isolation of DNA from tumor tissue. Classification of BRCAness was performed using multiple ligation-dependent probe amplification (MLPA). The tumor subtypes were determined immunohistochemically using resected specimens. Results Of the 262 TNBCs, the results of the MLPA assays showed that 174 (66.4%) tumors had BRCAness. Patients with BRCAness tumors were younger than patients with non-BRCAness tumors (P = 0.003). There was no significant difference between the two groups regarding their pathological stages. The BRCAness group had a significantly shorter recurrence-free survival (RFS) compared with the non-BRCAness group (P = 0.04) and had a shorter overall survival (OS) although this did not reach statistical significance. Adjuvant treatments with anthracycline-based regimens provided significantly greater benefits to the BRCAness group (P = 0.003 for RFS, and P = 0.03 for OS). Multivariate Cox proportional hazard model analysis showed that BRCAness was an independent negative prognostic factor, and the anthracycline-based adjuvant chemotherapy was an independent positive prognostic factor for both RFS and OS in TNBC. Conclusions The 66.4% patients of TNBCs showed BRCAness. BRCAness is essential as a biomarker in the subclassification of TNBCs and might be of use for predicting their prognosis. Furthermore, this biomarker might be a predictive factor for the effectiveness of anthracycline-based adjuvant chemotherapy for patients with TNBCs. PMID:27977696

    The purpose of this study was to conduct an exploratory analysis of the START examining the effects of resistance exercise training (RET) and aerobic exercise training (AET) on sarcopenia, dynapenia, and associated quality of life (QoL) changes in breast cancer (BC) patients receiving adjuvant chemotherapy. Participants were randomized to usual care (UC) (n = 70), AET (n = 64), or RET (n = 66) for the duration of chemotherapy. Measures of sarcopenia [skeletal muscle index (SMI)] and dynapenia [upper extremity (UE) and lower extremity (LE) muscle dysfunction (MD)] were normalized relative to age-/sex-based clinical cut-points. QoL was assessed by the Functional Assessment of Cancer Therapy-Anemia (FACT-An) scales. At baseline, 25.5 % of BC patients were sarcopenic and 54.5 % were dynapenic with both conditions associated with poorer QoL. ANCOVAs showed significant differences favoring RET over UC for SMI (0.32 kg/m(2); p = 0.017), UE-MD (0.12 kg/kg; p < 0.001), and LE-MD (0.27 kg/kg; p < 0.001). Chi-square analyses revealed significant effects of RET, compared to UC/AET combined, on reversing sarcopenia (p = 0.039) and dynapenia (p = 0.019). The reversal of sarcopenia was associated with clinically relevant improvements in the FACT-An (11.7 points [95 % confidence interval (CI) -4.2 to 27.6]), the Trial Outcome Index-Anemia (10.0 points [95 % CI -4.0 to 24.1]), and fatigue (5.3 points [95 % CI -1.5 to 12.1]). Early-stage BC patients initiating adjuvant chemotherapy have higher than expected rates of sarcopenia and dynapenia which are associated with poorer QoL. RET during adjuvant chemotherapy resulted in the reversal of both sarcopenia and dynapenia; however, only the reversal of sarcopenia was associated with clinically meaningful improvements in QoL.

There is therefore a necessity for an adjuvant that maintains the quality of life (QOL and immune function of cancer patients receiving anthracycline-based chemotherapies.Patients and methods: The present study investigated the effectiveness of the concomitant use of Lentinula edodes mycelia extract (LEM, an oral immunomodulator, with FEC75 (5-fluorouracil + epirubicin + cyclophosphamide therapy on host QOL and immune function in breast cancer patients with nodal metastases. Ten breast cancer patients with nodal metastases receiving surgery were enrolled in this study. Treatment with 5-fluorouracil (500 mg/m2, epirubicin (75 mg/m2, and cyclophosphamide (500 mg/m2 was performed every 21 days for two courses, and LEM (1800 mg/day by mouth was administered during the second course.Results: In the first course, hematological toxicity was observed and host QOL and immune function were exacerbated. In the second course, however, the number of white blood cells and lymphocytes did not decrease and host QOL was maintained. Furthermore, the cytotoxic activities of natural killer (NK and lymphokine-activated killer cells and the proportion of activated NK and NK T-cells in lymphocytes were maintained in the second course.Conclusion: It has been suggested that the concomitant use of LEM with FEC75 therapy can maintain host QOL and immune function, and offer important implications for an application of LEM as a useful oral adjuvant to anthracycline-based chemotherapies

    Medulloblastoma (MB) is one of the most common primary central nervous system tumors in children. Data is lacking of a large cohort of medulloblastoma patients in China. Also, our knowledge on the sensitivity of different molecular subgroups of MB to adjuvant radiation therapy (RT) or chemotherapy (CHT) is still limited. The authors performed a retrospective study of 173 medulloblastoma patients treated at two institutions from 2002 to 2011. Formalin-fixed paraffin embedded (FFPE) tissues were available in all the cases and sections were stained to classify histological and molecular subgroups. Univariate and multivariate analyses were used to investigate prognostic factors. Of 173 patients, there were 118 children and 55 adults, 112 males and 61 females. Estimated 5-year overall survival (OS) rates for all patients, children and adults were 52%, 48% and 63%, respectively. After multivariate analysis, postoperative primary radiation therapy (RT) and chemotherapy (CHT) were revealed as favorable prognostic factors influencing OS and EFS. Postoperative primary chemotherapy (CHT) was found significantly improving the survival of children (pSHH and Non-SHH/WNT subtypes) given postoperative adjuvant therapies. Postoperative primary RT was found to be a strong prognostic factor influencing the survival in all histological and molecular subgroups (pSHH subgroup (OS p = 0.020, EFS p = 0.049) and WNT subgroup (OS p = 0.003, EFS p = 0.016) but not in desmoplastic/nodular medulloblastoma (DMB) (OS p = 0.361, EFS p = 0.834) and Non-SHH/WNT subgroup (OS p = 0.127, EFS p = 0.055). Our study showed postoperative primary CHT significantly influence the survival of CMB, SHH subgroup and WNT subgroup but not in DMB and Non-SHH/WNT subgroup of MB.

    Administration of chemotherapy is associated with a wide array of symptoms affecting quality of life. Genetic risk factors for severity of chemotherapy-induced symptoms have not been determined. The present study aimed to explore the associations between polymorphisms in candidate genes and chemotherapy-induced symptoms. Women treated with at least two cycles of adjuvant doxorubicin and cyclophosphamide, with or without paclitaxel for early breast cancer (n = 105) completed the memorial symptom assessment scale and provided blood for genotyping. DNA was extracted from peripheral blood leukocytes and assayed for single nucleotide polymorphisms (SNPs) in GTP cyclohydrolase 1 (GCH1, rs10483639, rs3783641, and rs8007267), catecholamine-o-methyltransferase (COMT, rs4818), and 5-hydroxytryptamine (serotonin) receptor 3C (HTR3C, rs6766410, and rs6807362). Genotyping of HTR3C revealed a significant association between the presence of rs6766410 and rs6807362 SNPs (K163 and G405 variants) and increased severity of symptoms (p = 0.0001 and p = 0.007, respectively). Multiple regressions revealed that rs6766410 and rs6807362, but not age or stage at diagnosis, predicted severity of symptoms (p = 0.001 and p = 0.006, respectively) and explained 12 % of the variance in each regression model. No association was found between the genetic variants of CGH1 or COMT and symptom score. Our study indicates, for the first time, an association between variants of HTR3C and severity of chemotherapy-induced symptoms. Analyzing these genetic variants may identify patients at increased risk for the development of chemotherapy-induced symptoms and targeting the serotonin pathway may serve as a novel treatment strategy for these patients.

A Bayesian network meta-analysis was performed to investigate the efficacy of CCRT, IC + CCRT, and CCRT + AC on locally advanced nasopharyngeal cancer. The overall survival (OS with hazard ratios (HRs and locoregional recurrence rates (LRRs and distant metastasis rates (DMRs with risk ratios (RRs were investigated. After a comprehensive database search, eleven studies involving 2,626 assigned patients were included in this network meta-analysis. Compared with CCRT alone, IC + CCRT resulted in no significant improvement in OS or LRR and a marginal improvement in DMR (OS: HR =0.67, 95% credible interval (CrI 0.32–1.18; LRR: RR =1.79, 95% CrI 0.80–3.51; DMR: RR =1.79, 95% CrI 0.24–1.04 and CCRT + AC exhibited no beneficial effects on any of the endpoints of OS, LRR, or DMR (OS: HR =0.99, 95% CrI 0.64–1.43; LRR: RR =0.78, 95% CrI 0.43–1.32; DMR: RR =0.85, 95% CrI 0.57–1.24. As a conclusion, for locally advanced nasopharyngeal cancer, no significant differences in the treatment efficacies of CCRT, IC + CCRT, and CCRT + AC were found, with the exception of a marginally significant improvement in distant control observed following IC + CCRT compared with CCRT alone.

    Opportunistic infection with Pneumocystis jiroveci pneumonia (PCP) has not been recognized as a significant complication of early-stage breast cancer treatment. However, we have observed an increase in PCP incidence among patients receiving chemotherapy for early-stage breast cancer. Herein we identify risk factors for and calculate incidence of PCP in this population. We identified all cases of PCP at Dana-Farber Cancer Institute/Brigham and Women's Hospital (DFCI/BWH) from 1/1/2000 to 12/31/2013 in patients with stage I-III breast cancer treated with an adriamycin/cyclophosphamide (AC)-containing regimen. Nineteen cases of PCP in non-metastatic breast cancer patients were identified. All patients with PCP were diagnosed after receipt of either three or four cycles of AC chemotherapy on a dose-dense schedule. Patients who developed PCP were treated with median 16.4 mg prednisone equivalents/day as nausea prophylaxis for a median 64 days. The overall incidence of PCP among 2057 patients treated with neoadjuvant or adjuvant dose-dense AC for three or more cycles was 0.6 % (95 % confidence interval 0.3-1.0 %). No PCP was diagnosed in 1001 patients treated with non-dose-dense AC. There was one death from PCP. Women receiving dose-dense AC chemotherapy for early-stage breast cancer are at risk for PCP. Administering the same chemotherapy and corticosteroid dose over an 8-week versus 12-week non-dose-dense schedule appears to have created a novel infectious vulnerability. Replacing dexamethasone with alternative anti-emetics may mitigate this risk.

    Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

    A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials. (orig.)

    Chemotherapy-induced amenorrhea (CIA) is a side effect that occurs in patients with breast cancer (BC) as a result of chemotherapy. These patients require special treatments to avoid infertility and menopause. However, the factors controlling CIA, resumption of menstruation (RM), and persistence of menstruation after chemotherapy are unknown. The long-term prognosis for premenopausal patients with BC and the prognostic factors associated with CIA and RM are subject to debate. We performed a retrospective study by reviewing the medical records of 249 patients with BC (stage I to stage III) who were treated with cytotoxic chemotherapy. The median patient age was 43 (range, 26-55 years) and the median duration of follow-up was 64 months (range, 28-100 months). The medical records indicated that 219 patients (88.0%) scored as positive for the hormone receptor (HR); the majority of these patients completed chemotherapy and then received additional therapy of tamoxifen. Our analyses revealed that 88.0% (n = 219) of patients experienced CIA, and the percentage of RM during follow-up was 48.6% (n = 121). A total of 30 patients (12.0%) did not experience CIA. Disease-free survival (DFS) was affected by several factors, including tumour size ≥2 cm, node positivity, HR negative status, and body mass index ≥23 kg/m. Multivariate analysis indicated that tumour size ≥2 cm remained as a significant factor for DFS (hazard ratio = 3.3, P = 0.034). In summary, this study finds that the majority of premenopausal patients with BC (stage I to stage III) who receive chemotherapy experience CIA and subsequent RM. Although tumour size ≥2 cm is negatively associated with DFS, RM after CIA is not associated with poor prognosis.

    Full Text Available Methylation levels of long interspersed nucleotide elements (LINE-1 are representative of genome-wide methylation status and crucial in maintaining genomic stability and expression. Their prognostic impact on colon cancer patients receiving adjuvant chemotherapy has not been well established. We evaluated the association between LINE-1 methylation status and clinicopathologic features and postoperative oncological outcomes in stage III colon cancer patients.129 UICC stage III colon cancer patients who had received radical resection and FOLFOX adjuvant chemotherapy were enrolled. Global methylation was estimated by analyzing tumor LINE-1 methylation status using bisulfite-polymerase chain reaction (PCR and pyrosequencing assay. Demographics, clinicopathological data, and postoperative outcomes were recorded by trained abstractors. Outcome measurements included postoperative recurrence and disease-free survival. Univariate, multivariate, and survival analyses were conducted to identify prognostic factors of oncological outcomes.The LINE-1 methylation of all 129 patients was measured on a 0-100 scale (mean 63.3; median 63.7, standard deviation 7.1, LINE-1 hypomethylation was more common in patients aged 65 years and above (61.7%±7.6% vs. 64.6±6.4, p=0.019 and those with post-therapeutic recurrence (61.7±7.4 vs 64.3±6.7, p=0.041. Considering risk adjustment, LINE-1 hypomethylation was found to be an independent risk factor of post-therapeutic recurrence (Adjusted OR=14.1, p=0.012. Kaplan-Meier analysis indicated that patients in the low methylation group had shorter period of disease free survival (p=0.01. In a stratified analysis that included 48 patients with post-therapeutic recurrence, it was found that those who experienced shorter period of disease free survival (≦6 months appeared to have lower LINE-1 methylation levels than patients who reported of recurrence after 6 months (56.68±15.75 vs. 63.55±7.57, p=0.041.There was a

    Full Text Available Abstract Background HER2 and TOP2A parameters (gene status, mRNA and protein expression have individually been associated with the outcome of patients treated with anthracyclines. The aim of this study was to comprehensively evaluate the prognostic/predictive significance of the above parameters in early, high-risk breast cancer patients treated with epirubicin-based, dose-dense sequential adjuvant chemotherapy. Methods In a series of 352 breast carcinoma tissues from patients that had been post-operatively treated with epirubicin-CMF with or without paclitaxel, we assessed HER2 and TOP2A gene status (chromogenic in situ hybridization, mRNA expression (quantitative reverse transcription PCR, as well as HER2 and TopoIIa protein expression (immunohistochemistry. Results HER2 and TOP2A amplification did not share the same effects on their downstream molecules, with consistent patterns observed in HER2 mRNA and protein expression according to HER2 amplification (all parameters strongly inter-related, p values Conclusions This study confirms the favorable prognostic value of HER2/TOP2A co-amplification and the adverse prognostic value of high TOP2A mRNA expression extending it to the adjuvant treatment setting in early high-risk breast cancer. The strong adverse prognostic impact of high HER2/TOP2A mRNA co-expression needs further validation in studies designed to evaluate markers predictive for anthracyclines.

    Docetaxel and cyclophosphamide (TC) is a widely used breast cancer adjuvant regimen. We sought to compare the rates of febrile neutropenia (FN) between patients receiving no primary prophylaxis (PP) and those receiving PP with either granulocyte-colony stimulating factor (G-CSF) or antibiotics. We also analyzed cost-effectiveness of TC with and without either G-CSF or antibiotics. Charts were reviewed of all 340 patients who received adjuvant TC between January 2008 and December 2012 at two major cancer centers. Rates of FN in the three groups - no PP, PP with G-CSF and PP with antibiotics were compared. A Markov model was constructed comparing cost-effectiveness of PP with G-CSF, PP with antibiotics, and secondary prophylaxis (SP) with G-CSF after an episode of FN in a previous cycle. Costs were based on actual resource utilization and supplemented by the published literature, adjusted to 2012 Canadian dollars. Of the 73 (21%) patients who did not receive any PP, 23 (32%) of patients developed FN. Of the 192 (57%) patients receiving PP with G-CSF alone, only two (1%; p < 0.0001) developed FN; and of the 53 (16%) receiving PP with antibiotics alone, six (11%; p < 0.01) developed FN. From a cost-standpoint, PP with G-CSF was less cost-effective than PP with antibiotics. The rate of FN with TC chemotherapy exceeds 30%, and American Society of Clinical Oncology guidelines recommend PP with G-CSF in this situation. PP with antibiotics is more cost-effective, and is a reasonable option in resource-limited settings or for patients who decline or do not tolerate G-CSF.

    P-glycoprotein (Pgp)-related multidrug resistance (MDR) is frequently observed in acute non-lymphocytic leukemia (ANLL) and is associated with a poor response to standard chemotherapy. Cyclosporin A (CsA) is an effective downmodulator of Pgp-related MDR in vitro and has already been tested for that purpose in vivo also. Since Pgp is expressed in several normal cells and tissues, the modulation of Pgp can also modify total body exposure to antileukemic drugs and can alter and increase the toxicity of the antileukemic treatment. We report here the results of a study where 46 consecutive adult patients with ANLL were assigned to receive the same standard chemotherapy regimen of arabinosyl cytosine and idarubicin (IDA) for remission induction or consolidation, without or with CsA. Twenty-eight patients received 36 courses of chemotherapy without CsA and 18 patients received 32 courses of chemotherapy with CsA. CsA dose was 10-12.5 mg/kg/day and was given as a continuous i.v. infusion for 72 h. Whole blood CsA steady-state concentration ranged between 0.61 and 1.14 microM. The IDA area-under-the-curve was about twice as high in the cases that received CsA than in the other cases. CsA had no detectable effects on renal function and fluid balance, but significantly increased systemic blood diastolic pressure and conjugated bilirubine concentration. Furthermore, CsA-treated patients had greater, and more severe, oral and intestinal mucosal toxicity, with more severe adverse events, including more cases of gram-negative bacteremia, and with a delayed hemopoietic recovery. In conclusion, this study showed that an attempt at an effective downmodulation of Pgp-mediated MDR would substantially increase the hemopoietic and mucosal toxicity of antileukemic treatment and that the increase is accounted for, at least in part, by an increase of total body exposure to IDA.

    Full Text Available The PI3K-AKT pathway is frequently activated in breast cancer. PIK3CA mutations are most frequently found in the helical (exon 9 and kinase (exon 20 domains of this protein. The aim of the present study was to examine the role of different types of PIK3CA mutations in combination with molecular biomarkers related to PI3K-AKT signaling in patients with early breast cancer.Tumor tissue samples from 1008 early breast cancer patients treated with adjuvant chemotherapy in two similar randomized trials of HeCOG were examined. Tumors were subtyped with immunohistochemistry (IHC and FISH for ER, PgR, Ki67, HER2 and androgen receptor (AR. PIK3CA mutations were analyzed by Sanger sequencing (exon 20 and qPCR (exon 9 (Sanger/qPCR mutations. In 610 cases, next generation sequencing (NGS PIK3CA mutation data were also available. PIK3CA mutations and PTEN protein expression (IHC were analyzed in luminal tumors (ER and/or PgR positive, molecular apocrine carcinomas (MAC; ER/PgR negative / AR positive and hormone receptor (ER/PgR/AR negative tumors.PIK3CA mutations were detected in 235/1008 tumors (23% with Sanger/qPCR and in 149/610 tumors (24% with NGS. Concordance between the two methods was good with a Kappa coefficient of 0.76 (95% CI 0.69-0.82. Lobular histology, low tumor grade and luminal A tumors were associated with helical domain mutations (PIK3CAhel, while luminal B with kinase domain mutations (PIK3CAkin. The overall incidence of PIK3CA mutations was higher in luminal as compared to MAC and hormone receptor negative tumors (p = 0.004. Disease-free and overall survival did not significantly differ with respect to PIK3CA mutation presence and type. However, a statistically significant interaction between PIK3CA mutation status and PTEN low protein expression with regard to prognosis was identified.The present study did not show any prognostic significance of specific PIK3CA mutations in a large group of predominantly lymph-node positive breast cancer

    Objective: The proper time to commence adjuvant chemotherapy after primary surgery for breast cancer is unknown. It is usually prescribed within 2-3 months after definitive surgery. The aim of this retrospective study was to assess the impact of adjuvant chemotherapy (CT) delay beyond 3 weeks ( 21 days) in premenopausal patients with ER-absent tumors being treated for early stages breast cancer on overall survival (OS) and disease-free survival (DFS). Methods: This retrospective study was conducted through revision of medical records of premenopausal patients diagnosed with early stage I-IIIA breast cancer and ER-absent tumors who received adjuvant CT after definitive surgery at the Department of Clinical Oncology, Ain-Shams University Hospitals. Results: Between 2005 and 2008, 105 patients were retrospectively analyzed and included. Patients were divided into 2 groups: Group A including 48 patients who started adjuvant CT < 21 days of surgery and group B which included 57 patients who had CT delay < 21 days. Both groups were matched demographically. Comparisons of overall survival, and disease-free survival between group A and group B patients all favored group A. At 5-year the OS rates were 87% and 73% for groups A and B respectively (P = 0.001), while DFS rates were 85% and 64% in groups A and B respectively (P = 0.001). Analysis of other prognostic factors (age, T, N, grade, HER2 status, surgery type, CT type, local radiotherapy received) were analyzed. Only nodal status predicted for worse DFS (P = 0.05) and OS (P = 0.006). Conclusion: Delay in initiating adjuvant chemotherapy for early stage breast cancer patients with ER-absent tumors was associated with a decrease in both OS and DFS rates.

    Purpose: to prospectively assess health-related quality of life (HR-QoL) in women after conserving surgery for breast cancer during/after postoperative 3-D radiotherapy. Patients and methods: 109 consecutively treated patients were analyzed. HR-QoL was assessed at initiation (t1), end (t2), and 6 weeks after radiotherapy (t3) using the EORTC modules QLQ-C30/BR23. Patients were divided into three therapy groups. Group I comprised 41 patients (radiotherapy and adjuvant chemotherapy), group II 45 patients (radiotherapy and adjuvant hormonal therapy), and group III 23 patients (radiotherapy alone). Reliability was tested. Scale means were calculated. Univariate (ANOVA) and multivariate (MANCOVA) analyses were performed. Results: reliability testing revealed mean Cronbach's {alpha} > 0.70 at all measurement points. ANOVA/MANCOVA statistics revealed significantly better HR-QoL for patients in group II versus I. Patients receiving radiotherapy alone (group III) showed the best results in HR-QoL. However, scale mean differences between groups II and III were not significant. Conclusion: HR-QoL measurement using EORTC instruments during/after radiotherapy is reliable. Adjuvant chemotherapy significantly lowered HR-QoL versus hormones or radiotherapy alone. Chemotherapy patients did not recover longitudinally (from t1 to t3). (orig.)

    Full Text Available Abstract Background Cancer chemotherapy is frequently associated with a decline in general physical condition, exercise tolerance, and muscle strength and with an increase in fatigue. While accumulating evidence suggests that physical activity and exercise interventions during chemotherapy treatment may contribute to maintaining cardiorespiratory fitness and strength, the results of studies conducted to date have not been consistent. Additional research is needed to determine the optimal intensity of exercise training programs in general and in particular the relative effectiveness of supervised, outpatient (hospital- or physical therapy practice-based versus home-based programs. Methods This multicenter, prospective, randomized trial will evaluate the effectiveness of a low to moderate intensity, home-based, self-management physical activity program, and a high intensity, structured, supervised exercise program, in maintaining or enhancing physical fitness (cardiorespiratory fitness and muscle strength, in minimizing fatigue and in enhancing the health-related quality of life (HRQoL. Patients receiving adjuvant chemotherapy for breast or colon cancer (n = 360 are being recruited from twelve hospitals in the Netherlands, and randomly allocated to one of the two treatment groups or to a 'usual care' control group. Performance-based and self-reported outcomes are assessed at baseline, at the end of chemotherapy and at six month follow-up. Discussion This large, multicenter, randomized clinical trial will provide additional empirical evidence regarding the effectiveness of physical exercise during adjuvant chemotherapy in enhancing physical fitness, minimizing fatigue, and maintaining or enhancing patients' quality of life. If demonstrated to be effective, exercise intervention programs will be a welcome addition to the standard program of care offered to patients with cancer receiving chemotherapy.

    Docetaxel is an antineoplastic drug from the taxane family that inhibits tubulin polymerization. Its brand name is Taxotere. In mid-2010, the formulation of Taxotere changed from a two-vial preparation needing a predilution (T2V) to a one-vial ready-to-use preparation (T1V). The aim of this study was to compare the toxicity profile of these two formulations. This retrospective observational and monocentric study included all patients who received Taxotere-based chemotherapy (100 mg/m) as an adjuvant or a neoadjuvant treatment for localized breast cancer, following initial treatment with anthracycline-based chemotherapy. Patients received either T2V or T1V Taxotere depending on the period of treatment. The main endpoint was the ratio of the dose of Taxotere received to that scheduled (R=docetaxel dose received/docetaxel dose scheduled). The secondary endpoint was tolerance. A total of 97 patients were included: 39 in the T2V group and 58 in the T1V group. The ratio of docetaxel received/docetaxel scheduled was significantly lower in the T1V than in the T2V group (0.83 vs. 0.95, respectively; P=0.028). A higher proportion of patients did not receive the totality of the scheduled dose in the T1V than in the T2V group (28 vs. 8%, respectively; P=0.03). Furthermore, the proportion of patients experiencing cutaneous toxicity was significantly higher in the T1V than in the T2V group (50 vs. 15%, respectively; P<0.001) as well as for neurological toxicity (31 vs. 15%, respectively; P=0.03). The frequency of grade 3 toxicities was higher in the T1V than in the T2V group (50 vs. 8%, P=0.016). The frequency of idiosyncratic toxicities was not affected by the change of formulation (4.7 vs. 5.4%, P=0.98). This study shows that patients treated with the T1V formulation received a significantly smaller dose of Taxotere than patients treated with T2V. In this small retrospective study, no conclusions can be drawn as to why a change in formulation would be associated with

    The adoption of primary (PP) versus secondary prophylaxis (SP) of febrile neutropenia (FN), with granulocyte colony-stimulating factors (G-CSF), for adjuvant chemotherapy (AC) regimens in breast cancer (BC) could be affected by its "value for money". This systematic review examined (i) cost-effectiveness of PP versus SP, (ii) FN threshold at which PP is cost-effective including the guidelines 20 % threshold and (iii) potential impact of G-CSF efficacy assumptions on outcomes. The systematic review identified all cost-effectiveness/cost-utility analyses (CEA/CUA) involving PP versus SP G-CSF for AC in BC that met predefined inclusion/exclusion criteria. Five relevant CEA/CUA were identified. These CEA/CUA examined different AC regimens (TAC = 2; FEC-D = 1; TC = 2) and G-CSF formulations (filgrastim "F" = 4; pegfilgrastim "P" = 4) with varying baseline FN-risk (range 22-32 %), mortality (range 1.4-6.0 %) and utility (range 0.33-0.47). The potential G-CSF benefit, including FN risk reduction with P versus F, varied among models. Overall, relative to SP, PP was not associated with good value for money, as per commonly utilized CE thresholds, at the baseline FN rates examined, including the consensus 20 % FN threshold, in most of these studies. The value for money associated with PP versus SP was primarily dependent on G-CSF benefit assumptions including reduced FN mortality and improved BC survival. PP G-CSF for FN prevention in BC patients undergoing AC may not be a cost-effective strategy at the guidelines 20 % FN threshold.

    Phospholipase Cγ1 (PLCγ1) is highly expressed in several tumors. We have previously reported that both stable and inducible PLCγ1 down-regulation resulted in an almost complete inhibition of breast cancer-derived experimental lung metastasis formation. The aim of our study is to evaluate the association between the expression of PLCγ1 and of PLCγ1 phosphorylated at Tyr1253 (PLCγ1-pY1253) and at Tyr783 (PLCγ1-pY783) with the clinical outcome of patients with node negative, T1/T2 breast cancers. The study groups consisted of 292 (training set) and 122 (validation set) patients presenting with primary unilateral breast carcinoma (T1-T2), with no evidence of nodal involvement and distant metastases. PLCγ1, PLCγ1-pY1253 and PLCγ1-pY783 protein expression were assessed by immunohistochemistry on tissue microarrays and the results correlated with the clinical data using Kaplan-Meier curves and multivariate Cox regression analysis. Tumor cells while expressing variable proportions of cytoplasmic PLCγ1, express PLCγ1-pY1253 and PLCγ1-pY783 predominantly in the nucleus. High expression of PLCγ1, and of its activated forms, is associated with a worse clinical outcome in terms of incidence of distant metastases, and not of local relapse in T1-T2, N0 breast cancer patients undergone adjuvant chemotherapy. PLCγ1 over-expression appears to be a reliable predictive surrogate marker of development of metastases. Thus, targeting PLCγ1 pathways might represent a potential therapeutic approach for the prevention of metastatic disease in breast cancer.

    The benefit of adjuvant chemotherapy (AC) in locoregionally advanced nasopharyngeal carcinoma (NPC) is controversial. This study compared concurrent chemoradiotherapy plus AC (CCRT/AC) with CCRT. Pair-matched analysis based on eight clinicopathological features of 244 patients treated with platinum-based CCRT/AC or CCRT alone was performed. Survival outcomes were assessed using the Kaplan-Meier method and log-rank test. Toxicities and response rates were compared using Fisher's exact test. Four-year overall survival, progression-free survival, distant failure-free survival, and locoregional failure-free survival were 72 %, 61 %, 71 %, and 81 %, respectively, for the CCRT arm, compared to 74 % (hazard ratio, HR 0.89; 95 % confidence interval, CI 0.64-1.23; P = 0.474), 62 % (HR 0.91, 95 % CI 0.68-1.20, P = 0.489), 73 % (HR 0.84, 95 % CI 0.59-1.18, P = 0.316), and 84 % (HR 0.84, 95 % CI 0.52-1.24, P = 0.323), respectively, for the CCRT/AC arm. Cox multivariate regression analysis demonstrated AC was not an independent prognostic factor. Overall, there was a higher incidence of grade 3-4 toxicities in the CCRT/AC arm. The most common grade 3-4 adverse events in the CCRT/AC arm were vomiting (27 %), nausea (43 %), leukopenia/neutropenia (23 %), thrombocytopenia (8.8 %), and anemia (6.2 %). Addition of AC to CCRT increased toxicities but did not improve survival in locoregionally advanced NPC. (orig.)

  14. Digital expression profiling identifies RUNX2, CDC5L, MDM2, RECQL4, and CDK4 as potential predictive biomarkers for neo-adjuvant chemotherapy response in paediatric osteosarcoma.

    Directory of Open Access Journals (Sweden)

    Jeffrey W Martin

    Full Text Available Osteosarcoma is the most common malignancy of bone, and occurs most frequently in children and adolescents. Currently, the most reliable technique for determining a patients' prognosis is measurement of histopathologic tumor necrosis following pre-operative neo-adjuvant chemotherapy. Unfavourable prognosis is indicated by less than 90% estimated necrosis of the tumor. Neither genetic testing nor molecular biomarkers for diagnosis and prognosis have been described for osteosarcomas. We used the novel nanoString mRNA digital expression analysis system to analyse gene expression in 32 patients with sporadic paediatric osteosarcoma. This system used specific molecular barcodes to quantify expression of a set of 17 genes associated with osteosarcoma tumorigenesis. Five genes, from this panel, which encoded the bone differentiation regulator RUNX2, the cell cycle regulator CDC5L, the TP53 transcriptional inactivator MDM2, the DNA helicase RECQL4, and the cyclin-dependent kinase gene CDK4, were differentially expressed in tumors that responded poorly to neo-adjuvant chemotherapy. Analysis of the signalling relationships of these genes, as well as other expression markers of osteosarcoma, indicated that gene networks linked to RB1, TP53, PI3K, PTEN/Akt, myc and RECQL4 are associated with osteosarcoma. The discovery of these networks provides a basis for further experimental studies of role of the five genes (RUNX2, CDC5L, MDM2, RECQL4, and CDK4 in differential response to chemotherapy.

    The aim of this study was to compare the effectiveness and toxicity of neoadjuvant chemotherapy regimens, xeloda/epirubicin/cyclophosphamide (XEC) vs 5-fluorouracil/epirubicin/cyclophosphamide (FEC), followed by adjuvant chemotherapy regimens, capecitabine/taxotere (XT) vs taxotere (T), in axillary lymph node (LN)-positive early-stage breast cancer. In this randomized, Phase III trial, 137 patients with operable primary breast cancer (T2-0, N0-1) who were tested axillary LN positive through aspiration biopsy of axillary LNs were randomized (1:1) to four 3-weekly cycles of XEC or FEC. Patients underwent surgery within 4–6 weeks after the fourth cycle, followed by four adjuvant cycles of 3-weekly XT or T. The primary end point was tumor pathological complete response. Toxicity profiles were secondary objectives. In total, 131 patients had clinical and radiological evaluation of response and underwent surgery. Treatment with XEC led to an increased rate of pathological complete response in primary tumor (18% vs 6%, respectively, P=0.027) and objective remission rate (87% vs 73%, P=0.048) compared to FEC. Clinical complete response occurred in 20% and 7% for XEC and FEC, respectively. Compared to FEC, XEC was associated with more hand-foot syndrome (57% vs 11%, P<0.001) and 3/4 grade nausea/vomiting/diarrhea (30% vs 14%, P=0.034) but less phlebitis (3% vs 14%, P=0.035). XT and T adjuvant chemotherapy regimens were well tolerated: treatment-related 3/4 grade adverse events occurred in 28% and 17% of patients receiving XT and T, respectively. PMID:27354816

    We present a 3-yr-old girl with a virilizing adrenocortical carcinoma invading into the right atrium with histological high-grade malignancy and p53 mutation. Development of facial acne and pubic hair were noted at 3 yr and 2 mo. The levels of androgens were high. Diurnal variation in ACTH and cortisol were absent. Abdominal computed tomography revealed a large right suprarenal mass, with extension into the inferior vena cava and right atrium. Based on the diagnosis of a right virilizing adrenocortical tumor with Cushing syndrome, surgery was performed by a combined thoracoabdominal approach with the patient on cardiopulmonary bypass. The tumor was 7 × 5.5 × 3.5 cm in size, and weighed 95 g. The histological diagnosis was adrenocartical carcinoma with high-grade malignancy according to the category of Weiss. A heterozygous mutation of the p53 tumor-suppressor gene (codon 248 CGC→TGG) was found. We did not perform adjuvant chemotherapy because of radical resection on macroscopic observation and no metastasis in radiological findings. Five months after the surgery, her chest X ray and computed tomography revealed multiple lung metastases and a single liver metastasis. In this type of patient with histological high-grade malignancy and p53 mutations, postoperative adjuvant chemotherapy is indicated even if macroscopic total surgical removal had been performed.

    The diagnosis and treatment of colorectal cancer is one of the main diseases of gastrointestinal surgeons. It is very important to master the adjuvant chemotherapy of colorectal cancer for gastrointestinal surgeons. In recent years, with the development of a number of clinical trials and the appearance of new drugs, fluorouracil combined with oxaliplatin had been established as the standard regimen of adjuvant chemotherapy for colorectal cancer. In the current guidelines, stage III( colon cancer is the indication for adjuvant chemotherapy, while stage II( colon cancer should receive adjuvant chemotherapy is uncertain. Unlike colon cancer, adjuvant therapy of rectal cancer is not evidence-based. Especially, the indication and duration of adjuvant chemotherapy for rectal cancer after neoadjuvant chemoradiotherapy remain controversial. Adjuvant therapy of colorectal cancer still needs further investigation.

In this randomized, Phase III trial, 137 patients with operable primary breast cancer (T2-0, N0-1 who were tested axillary LN positive through aspiration biopsy of axillary LNs were randomized (1:1 to four 3-weekly cycles of XEC or FEC. Patients underwent surgery within 4–6 weeks after the fourth cycle, followed by four adjuvant cycles of 3-weekly XT or T. The primary end point was tumor pathological complete response. Toxicity profiles were secondary objectives. In total, 131 patients had clinical and radiological evaluation of response and underwent surgery. Treatment with XEC led to an increased rate of pathological complete response in primary tumor (18% vs 6%, respectively, P=0.027 and objective remission rate (87% vs 73%, P=0.048 compared to FEC. Clinical complete response occurred in 20% and 7% for XEC and FEC, respectively. Compared to FEC, XEC was associated with more hand-foot syndrome (57% vs 11%, P<0.001 and 3/4 grade nausea/vomiting/diarrhea (30% vs 14%, P=0.034 but less phlebitis (3% vs 14%, P=0.035.

    The aim of this retrospective study was to assess toxicity and efficacy of adjuvant high-dose chemotherapy (HDC) and autologous hematopoietic stem cell transplantation (AHSCT) in 583 high-risk breast cancer (BC) patients (>3 positive nodes) who were transplanted between 1995 and 2005 in Europe. All patients received surgery before transplant, and 55 patients (9.5%) received neoadjuvant treatment before surgery. Median age was 47.1 years, 57.3% of patients were premenopausal at treatment, 56.5% had endocrine-responsive tumors, 19.5% had a human epidermal growth factor receptor 2 (HER2)-negative tumor, and 72.4% had ≥10 positive lymph nodes at surgery. Seventy-nine percent received a single HDC procedure. Overall transplant-related mortality was 1.9%, at .9% between 2001 and 2005, whereas secondary tumor-related mortality was .9%. With a median follow-up of 120 months, overall survival and disease-free survival rates at 5 and 10 years in the whole population were 75% and 64% and 58% and 44%, respectively. Subgroup analysis demonstrated that rates of overall survival were significantly better in patients with endocrine-responsive tumors, <10 positive lymph nodes, and smaller tumor size. HER2 status did not affect survival probability. Adjuvant HDC with AHSCT has a low mortality rate and provides impressive long-term survival rates in patients with high-risk BC. Our results suggest that this treatment modality should be considered in selected high-risk BC patients and further investigated in clinical trials.

    Full Text Available Abstract Background Colon cancer is a public health problem worldwide. Adjuvant chemotherapy after surgical resection for stage III colon cancer has been shown to improve both progression-free and overall survival, and is currently recommended as standard therapy. However, its value for patients with stage II disease remains controversial. When this study was designed 5-fluorouracil (5FU plus leucovorin (LV was standard adjuvant treatment for colon cancer. Irinotecan (CPT-11 is a topoisomerase I inhibitor with activity in metastatic disease. In this multicenter adjuvant phase III trial, we evaluated the addition of irinotecan to weekly 5FU plus LV in patients with stage II or III colon cancer. Methods The study included 873 eligible patients. The treatment consisted of weekly administration of irinotecan 80 mg/m2 intravenously (IV, LV 200 mg/m2 and 5FU 450 mg/m2 bolus (Arm A versus LV 200 mg/m2 and 5FU 500 mg/m2 IV bolus (Arm B. In Arm A, treatments were administered weekly for four consecutive weeks, followed by a two-week rest, for a total of six cycles, while in Arm B treatments were administered weekly for six consecutive weeks, followed by a two-week rest, for a total of four cycles. The primary end-point was disease-free survival (DFS at three years. Results The probability of overall survival (OS at three years was 0.88 for patients in Arm A and 0.86 for those in Arm B, while the five-year OS probability was 0.78 and 0.76 for patients in Arm A and Arm B, respectively (P = 0.436. Furthermore, the probability of DFS at three years was 0.78 and 0.76 for patients in Arm A and Arm B, respectively (P = 0.334. With the exception of leucopenia and neutropenia, which were higher in patients in Arm A, there were no significant differences in Grades 3 and 4 toxicities between the two regimens. The most frequently recorded Grade 3/4 toxicity was diarrhea in both treatment arms. Conclusions Irinotecan added to weekly bolus 5FU plus LV did not result

    Purpose. - To assess the benefit of breast surgery for inflammatory breast cancer. Patients and methods. - This retrospective series was based on 232 patients treated for inflammatory breast cancer. All patients received primary chemotherapy followed by either exclusive radiotherapy (118 patients, 51%) or surgery with or without radiotherapy (114 patients, 49%). The median follow-up was 11 years. Results. - The two groups were comparable apart from fewer tumors smaller than 70 mm (43% vs 33%, P = 0.003), a higher rate of clinical stage N2 (15% vs 5%, P = 0.04) and fewer histopathological grade 3 tumors (46% vs 61%, P < 0.05) in the no-surgery group. The addition of surgery was associated with a significant improvement in locoregional disease control (P = 0.04) but with no significant difference in overall survival rates or disease-free intervals. Late toxicities were not significantly different between the two treatment groups except for a higher rate of fibrosis in the no-surgery group (P < 0.0001), and more lymphedema in the surgery group (P = 0.002). Conclusion. - Our data suggest an improvement in locoregional control in patients treated by surgery, in conjunction with chemotherapy and radiotherapy, for inflammatory breast cancer. (authors)

    Full Text Available Abstract Background Pseudomyxoma peritonei (PMP is a rare condition characterized by mucinous tumors, disseminated intra-peritoneal implants, and mucinous ascites. So far its diagnosis remains challenging to most clinicians. Case presentation A 55-year-old male patient had suffered from acute onset of abdominal pain and abdominal distension for one day prior to his admission. Physical examination revealed tenderness over the right lower quadrant of the abdomen without diffuse muscle guarding. A large amount of ascites was identified by abdominal computed tomography (CT scan. Paracentesis showed the appearance of sticky mucinous ascites. He underwent laparotomy under the impression of pseudomyxoma peritonei. There was a lot of mucinous ascites, one appendiceal tumor and multiple peritoneal implants disseminated from the subphrenic space to the recto-vesicle pouch. Pseudomyxoma Peritonei caused by mucinous adenocarcinoma of appendiceal origin, was confirmed by histopathology. We performed an excision of the appendiceal tumor combined with copious irrigation and debridement. After the operation, he received 10 cycles of systemic chemotherapy with FOLFOX4 regimen, without specific morbidity. Follow-up of abdominal CT and colonoscopy at post-operative 17 months showed excellent response without evidence of local recurrence or distal metastasis. He made an uneventful recovery (up to the present for 21 months after the operation. Conclusion This case report emphasizes the possible new role of systemic chemotherapy in the treatment of patients with this rare clinical syndrome.

    Purpose: The development of breast cancer-related lymphedema (LE) is closely related to the number of dissected axillary lymph nodes (N-ALNs), chemotherapy, and radiation therapy. In this study, we attempted to estimate the risk of LE based on combinations of these treatment-related factors. Methods and Materials: A total of 772 patients with breast cancer, who underwent primary surgery with axillary lymph node dissection from 2004 to 2009, were retrospectively analyzed. Adjuvant chemotherapy (ACT) was performed in 677 patients (88%). Among patients who received radiation therapy (n=675), 274 (35%) received supraclavicular radiation therapy (SCRT). Results: At a median follow-up of 5.1 years (range, 3.0-8.3 years), 127 patients had developed LE. The overall 5-year cumulative incidence of LE was 17%. Among the 127 affected patients, LE occurred within 2 years after surgery in 97 (76%) and within 3 years in 115 (91%) patients. Multivariate analysis showed that N-ALN (hazard ratio [HR], 2.81; P<.001), ACT (HR, 4.14; P=.048), and SCRT (HR, 3.24; P<.001) were independent risk factors for LE. The total number of risk factors correlated well with the incidence of LE. Patients with no risk or 1 risk factor showed a significantly lower 5-year probability of LE (3%) than patients with 2 (19%) or 3 risk factors (38%) (P<.001). Conclusions: The risk factors associated with LE were N-ALN, ACT, and SCRT. A simple model using combinations of these factors may help clinicians predict the risk of LE.

    The outlook for patients with pancreatic cancer has been grim. There have been major advances in the surgical treatment of pancreatic csncer, leading to a drsmatic reduction in post-operative mortality from the development of high volume specialized centres. This stimulated the study of adjuvant and neoadjuvant treatments in pancreatic cancer including chemoradiotherapy and chemotherapy. Initial protocols have been based on the original but rather small GITSG study first reported in 1985. There have been two large European trials totalling over 600 patients (EORTC and ESPAC-1) that do not support the use of chemoradiation as adjuvant therapy. A second major finding from the ESPAC-1 trial (541 patients randomized) was some but not conclusive evidence for a survival benefit associated with chemotherapy. A third major finding from the ESPAC-1 trial was that the quality of life was not affected by the use of adjuvant treatments compared to surgery alone.The ESPAC-3 trial aims to assess the definitive use of adjuvant chemotherapy in a randomized controlled trial of 990 patients.

    Purpose. - To determine whether exclusive radiotherapy could be a therapeutic option after complete clinical response (cCR) to neo-adjuvant chemotherapy (NCT) for early breast cancers (EBC). Patients and methods. - Between 1985 and 1999, 1477 patients received neo-adjuvant chemotherapy for early breast cancer considered to be too large for primary conservative surgery. Of 165 patients with complete clinical response, 65 were treated by breast surgery (with radiotherapy) and 100 by exclusive radiotherapy. Results. - The two groups were comparable in terms of baseline characteristics, except for larger initial tumor sizes in the exclusive radiotherapy group. There were no significant differences in overall, disease-free and metastasis-free survivals. Five-year and 10-year overall survivals were 91 and 77% in the no surgery group and 82 and 79% in the surgery group, respectively (P = 0.9). However, a non-significant trend towards higher locoregional recurrence rates (LRR) was observed in the no surgery group (31 vs. 17% at 10 years; P = 0.06). In patients with complete responses on mammography and/or ultrasound, LRR were not significantly different (P = 0.45, 10-year LRR: 21 in surgery vs. 26% in exclusive radiotherapy). No significant differences were observed in terms of the rate of cutaneous, cardiac or pulmonary toxicities. Conclusion. - Surgery is a key component of locoregional treatment for breast cancers that achieved complete clinical response to neo-adjuvant chemotherapy. (authors)

    PURPOSE To determine the frequency and prognostic association of molecular markers by anatomic tumor site in patients with stage III colon carcinomas. Experimental Design In a randomized trial of adjuvant FOLFOX + cetuximab, BRAFV600E and KRAS (exon 2) mutations and DNA mismatch repair (MMR) proteins were analyzed in tumors (N=3,018) in relationship to tumor location including subsite. Cox models were used to assess clinical outcome including overall survival (OS). RESULTS KRAS codon 12 mutations were most frequent at the splenic flexure and cecum; codon 13 mutations were evenly distributed. BRAF mutation frequency sharply increased from transverse colon to cecum in parallel with deficient (d) MMR. Non-mutated BRAF or KRAS tumors progressively decreased from sigmoid to transverse (all p<0.0001). Significantly poorer OS was found for mutant KRAS in distal [HR, 1.98 (1.49–2.63); p<.0001] vs proximal [1.25 (0.97–1.60), p=.079] cancers. BRAF status and outcome were not significantly associated with tumor site. Proximal vs distal dMMR tumors had significantly better outcome. An interaction test was significant for tumor site by KRAS (padjusted=.043) and MMR (padjusted=.010) for OS. Significant prognostic differences for biomarkers by tumor site were maintained in the FOLFOX arm. Tumor site was independently prognostic with a stepwise improvement from cecum to sigmoid (OS: padjusted=0.001). CONCLUSIONS Mutations in BRAF or KRAS codon 12 were enriched in proximal cancers whereas non-mutated BRAF/KRAS were increased in distal tumors. Significant differences in outcome for KRAS mutations and dMMR were found by tumor site, indicating that their interpretation should occur in the context of tumor location. PMID:26187617

    There is no optimal treatment for breast cancers lacking estrogen (ER) and progesterone (PgR) receptors in elderly women with co-morbidities that prevent use of "standard chemotherapy regimens" such as AC or CMF. The CASA trial studied pegylated liposomal doxorubicin (PLD) and low dose, metronomic cyclophosphamide + methotrexate (CM) for older (>65), vulnerable women with operable, ER and PgR-negative breast cancer. After two years the trial closed early, due to slow and inadequate accrual, with 77 patients (38:PLD, 36:CM, 3:nil). Sixty-eight percent completed PLD; 83% completed CM (both 16 weeks). Patients on PLD reported worse quality of life, cognitive and physical functioning than non-PLD regimens (primarily CM). At a median follow-up of 42 months, 81% of randomized patients remained free of any breast cancer recurrence. Based on our limited experience, PLD and CM may be reasonable options for further study for elderly vulnerable patients with endocrine nonresponsive breast cancer.

    Full Text Available El cáncer de pulmón constituye una de las principales causas de mortalidad en todo el mundo. Su incidencia se relaciona directamente al uso del tabaco. Puede clasificarse a los pacientes en tres grupos: con enfermedad localizada o resecable, con enfermedad localmente avanzada y con enfermedad metastásica. Excepto algunos casos, el primer grupo es pasible de curación. En ellos la cirugía es el tratamiento de elección. El advenimiento de quimioterapia sistémica efectiva, estudios cooperativos bien diseñados y mejor comprensión del comportamiento biológico han logrado mejorar la sobrevida global por primera vez en una centuria. El rol de la quimioterapia adyuvante encuentra un escenario cierto, luego de una década de estudios clínicos. El objetivo de este artículo es realizar una revisión de la evidencia disponible que ha colocado a las combinaciones basadas en cisplatino como el tratamiento de elección luego de la cirugía en los estadios II-IIIA del cáncer de pulmón de células no pequeñas.Lung cancer is one of the leading causes of death worldwide. Its incidence is directly related to tobacco use. The patients can be classified in three large groups: those with localized or resectable disease; those with locally advanced disease and lastly those with metastatic disease. Except for anecdotal cases, in the first group cure is possible. For these patients surgery is the treatment of choice. However, with the appearance of effective systemic chemotherapy, well designed cooperative studies and a better understanding of the biological behaviour, overall survival has improved for the first time in a hundred years. The role of adjuvant chemotherapy is a true option after a decade of clinical trials. The objective of this article is to perform a review of the available evidence which has made cisplatin based combinations is the treatment of choice after surgery for stages II-IIIA non-small cell lung cancer.

    Objective To compare the effect of two different exercise program on rehabilitation in breast cancer patients after postoperative adjuvant chemotherapy. Methods A total of 120 breast cancer patients after modified radical mastectomy and 10 to 12 months postoperative adjuvant chemotherapy were randomly divided into two groups. Four-month of music exercises versus aerobic exercises and simplified Tai Ji were provided for the patients in the control group and experimental group,respectively. Results After 4-months exercises,only the patients' elbow flexor strength was significantly improved while the bone mineral density was reduced in the control group (P<0.05). In the experimental group,the patients' limb muscle strength,lung function and body shape were significantly improved (P<0.05),and no significant change in the bone mineral density(P>0.05). Compared with the control group,the patients' vital capacity was significantly higher,while the body mass index(BMI)was significantly lower in the experimental group(P<0.01). No significant difference was found on the quality of life between the two groups (P>0.05). Conclusion Both the two exercise programs can enhance the elbow flexor strength. Tai Ji and aerobic exercise can also promote the restoration of limb function,improve lung function and body shape,and slow bone loss,thus improving the overall rehabilitation outcomes.%目的 比较两种运动方案对乳腺癌患者辅助化疗后康复效果的影响.方法 将行乳腺癌改良根治术且完成术后辅助化疗10~12个月的女性患者120例随机分为两组,进行为期4个月的锻炼,试验组实施太极有氧组合运动,对照组采用传统音乐康复操.结果 锻炼4个月后,试验组在患侧上肢肌力、肺功能和体形方面均较入组时改善(P0.05);对照组患侧上肢肘屈肌力较入组时增强,股骨密度较入组时下降(P0.05).结论 两种运动方案均可增强患侧上肢肘屈肌力;太极有氧组合运动

    Metastatic gastric cancer remains a non-curative disease.Palliative chemotherapy has been demonstrated to prolong survival without quality of life compromise. Many single-agents and combinations have been confirmed to be active in the treatment of metastatic disease. Objective response rates ranged from 10-30% for single-agent therapy and 30-60% for polychemotherapy. Results of phase Ⅱ and Ⅲ studies are reviewed in this paper as well as the potential efficacy of new drugs. For patients with localized disease, the role of adjuvant and neoadjuvant chemotherapy and radiation therapy is discussed.Most studies on adjuvant chemotherapy failed to demonstrate a survival advantage, and therefore, it is not considered as standard treatment in most centres. Adjuvant immunochemotherapy has been developed fundamentally in Korea and Japan. A meta-analysis of phase Ⅲ trials with OK-432 suggested that immunochemotherapy may improve survival of patients with curatively resected gastric cancer. Based on the results of US Intergroup 0116study, postoperative chemoradiation has been Accepted as standard care in patients with resected gastric cancer in North America. However, the results are somewhat confounded by the fact that patients underwent less than a recommended D1 lymph node dissection and the pattern of recurrence suggested a positive effect derived from local radiotherapy without any effect on micrometastatic disease.Neoadjuvant chemotherapy or chemoradiation therapy remains experimental, but several phase Ⅱstudies are showing promising results. Phase Ⅲ trials are needed.

    In 1996, a multicenter randomized study comparing after breast-conservative surgery. sequential vs concurrent adjuvant chemotherapy (CT) with radiation therapy (RT) was initiated (ARCOSEIN study). Seven hundred sixteen patients were included in this trial. After a median follow-up of 6.7 (4.3 -9) years, we decided to prospectively evaluate the late effects of these two strategies. Patients and methods - A total of 297 patients were asked to follow-up from the five larger including institutions. Seventy-two percent (214 patients) were eligible for late toxicity. After breast-conserving surgery with axillary dissection, patients were treated either with sequential treatment with CT first followed by RT (arm A) or CT administered concurrently with RT (arm B). In all patients, CT regimen combined mitoxantrone (12 mg/m{sup 2}). 5-FU (500 mg/m{sup 2}), and cyclophosphamide (500 mg/m{sup 2}), 6 cycles (day 1-day 21). In arm B, patients received concurrently the first 3 cycles of CT with RT. In arm A, RT started 3 to 5 weeks after the 6. cycle of CT. Conventional RT was delivered to the whole breast using a 2 Gy-fraction protocol to a total dose of 50 Gy ({+-} boost to the primary tumour bed). The assessment of toxicity was blinded to treatment and was graded by the radiation oncologist according to the LENT-SOMA scale. Skin pigmentation was also evaluated using a personal 5-points scoring system (excellent, good, moderate, poor, very poor). Results - Among the 214 evaluated patients, 107 were treated in each arm. The two populations were homogeneous for patients', tumors' and treatment characteristics. Subcutaneous fibrosis (SF), telangiectasia (T), skin pigmentation (SP), and breast atrophy (BA) were significantly increased in arm B. Twenty patients experienced grade superior or equal to 2 (SF) in arm B vs five in arm A (P 0.003). Twenty-five and seven patients showed grade superior or equal to 2 (T) in ann B and A, respectively (P = 0.001). Forty-four and

    The use of chemotherapy to treat cancer began at the start of the 20th century with attempts to narrow the universe of chemicals that might affect the disease by developing methods to screen chemicals using transplantable tumors in rodents. It was, however, four World War II-related programs, and the effects of drugs that evolved from them, that provided the impetus to establish in 1955 the national drug development effort known as the Cancer Chemotherapy National Service Center. The ability of combination chemotherapy to cure acute childhood leukemia and advanced Hodgkin's disease in the 1960s and early 1970s overcame the prevailing pessimism about the ability of drugs to cure advanced cancers, facilitated the study of adjuvant chemotherapy, and helped foster the national cancer program. Today, chemotherapy has changed as important molecular abnormalities are being used to screen for potential new drugs as well as for targeted treatments.

    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.

    Objective: to assess the treatment of breast cancer T2 and T3(T > = 4 cm), through neoadjuvant chemotherapy, quadrantectomy and high-dose-rate (HDR) brachytherapy as a boost, complementary radiotherapy and adjuvant chemotherapy, considering its method problems, its esthetics results, the aspect of local control, overall survival, and disease-free survival. Patients and method: this clinical prospective descriptive study was based on the evaluation of 26 patients ranging from 30 to 70 years old, with infiltrating ductal carcinoma, clinical stage IIB and IIIA, responsive to the neoadjuvant chemotherapy. Early and late radiotherapy complications were evaluated according to the criteria established by the RTOG/EORTC (Radiotherapy and Oncology Group /European Organization for Research and Treatment of Cancer) groups. Esthetics evaluation was done in accordance with the criteria set by a plastic surgeon. Local control was evaluated by clinical method, mammography and ultrasonography. Overall survival (OS) and the disease-free survival (DFS) were assessed according to Kaplan-Meier methodology. All the patients were treated at the Dr. Arnaldo Vieira de Carvalho Cancer Institute, from June/1995 to November/2001, and evaluated in March, 2002, with median follow-up of 28.7 months. Results: early complications were observed in 8 patients (30.6%). Two patients were classified as G3 and G4 (RTOG/EORTC). Six patients had late complications and three of them (11.5%) were classified as G3 and G4. One patient (3.8%) had local recurrence, 64 months after having local treatment. Esthetics results were considered good or regular in 16 patients (60.5%) out of 24 patients who were examined. Overall survival and disease-free survival in 24, 36 and 60 months were 100%, 92.3% and 83.1% respectively. Conclusion: early and late radiotherapy complications were considerate high when compared to literature, but esthetic results were considered acceptable. RL, OS and DFS were comparable to other

    Objective: The aim of the study was to investigate the prospective study if treatment with arsenic trioxide (As2O3) could enhance disease-free survival as adjuvant post-operative chemotherapy for gastric cancer patients and protect bone marrow from the negative effects of chemotherapy. Methods: 84 adults were randomized into two groups. Patients in treat- ment group were treated with As203 and FOLFOX regimen, the other were administered with FOLFOX regimen only. Results: Four patients were withdrawn in treatment group after 3-4 cycles and the reasons were headache and fidgety (n = 2), ar- rhythmia (n = 1) and AST/ALT elevation (n = 1), while 1 patient in control group after 4 cycles for neutropenia. In the treatment group, the median DFS was 28.34 months (95% CI, 25-33 months). While in control group, the median DFS was 24.50 months (95% CI, 20-30 months). This difference was not statistically significant (chi-square: 2.8885; P value: 0.0892). Pa- tients in the same subgroup of node-positive was 29 in the treatment group and 32 in control group, respectively. The median DFS was 27.87 months (95% CI, 25-31 months) in the treatment group and 24.18 months (95% CI, 19-31 months) in the control group with promising statistical significance (HR 1.89; chi-square: 4.78; P value: 0.0287). The most common grades 3-4 toxicity was leucopenia (n = 11) in control group and the difference was significant (chi-square: 3.9768, P value: 0.046) compared with that in treatment group (n = 4). Conclusion: The combination of arsenic trioxide and FOLFOX regimen has a potential advantage of enhancing disease-free survival in patients with gastric cancer in nodal-positive status as post-opera- tive chemotherapy, and protect bone marrow from the negative effects of chemotherapy.

    Objective: To compare the efficacy of induction chemotherapy (IC) plus intensity-modulated radiotherapy (IMRT) with that of concurrent chemo-radiotherapy (CCRT) plus adjuvant chemotherapy (AC) for patients with loco-regionally advanced naso-pharyngeal carcinoma (NPC). Methods:Data of 240 patients with loco-regionally advanced NPC were reviewed. These patients were admitted to the Sun Yat-sen University Cancer Center between January 2004 and December 2008. Among the 240 patients, 117 under-went the IC+IMRT and 123 were treated with the CCRT+AC. The IC+IMRT group received a regimen including cisplatin and 5-fluoro-uracil (5-FU). The CCRT+AC group received cisplatin concurrently with radiotherapy and subsequently received adjuvant cisplatin and 5-FU. The survival rates of the patients were assessed by Kaplan-Meier analysis, and the survival curves were compared by Log-rank test. Multivariate analysis was conducted using Cox proportional hazard regression model. Results:The 5-year overall survival (OS), disease-free survival, distant metastasis-free survival, local relapse-free survival, and the nodal relapse-free survival were 78.0%versus 78.7%, 68.9%versus 67.5%, 79.0%versus 77.0%, 91.6%versus 91.0%, and 95.3%versus 93.7%in the IC+IMRT and CCRT+AC groups, respectively. The survival between the two groups exhibited no significant differences. Higher rates of Grades 3 to 4 nau-sea-vomiting (8.1%vs. 1.7%, P=0.023) and leukopenia (9.7%vs. 0.9%, P=0.006) were observed in the CCRT+AC group. Multivariate analysis revealed that N stage and age were significant prognostic factors for the OS of the patients with loco-regionally advanced NPC. Conclusion:The treatment outcomes of IC+IMRT and CCRT+AC were similar. Distant metastasis remained as the predominant mode of treatment failure.%目的:比较诱导化疗加调强放疗和同期放化疗加辅助化疗治疗局部晚期鼻咽癌的疗效。方法:收集2004年1月至2008年12月中山大学肿瘤医院收治的经病

    Pancreatic adenocarcinoma is one of the most aggressive human malignancies,ranking 4th among causes for cancer-related death in the Western world including the United States.Surgical resection offers the only chance of cure,but only 15 to 20 percent of cases are potentially resectable at presentation.Different studies demonstrate and confirm that advanced pancreatic cancer is among the most complex cancers to treat and that these tumors are relatively resistant to chemotherapy and radiotherapy.Currently there is no consensus around the world on what constitutes "standard"adjuvant therapy for pancreatic cancer.This controversy derives from several studies,each fraught with its own limitations.Standards of care also vary somewhat with regard to geography and economy,for instance chemo-radiotherapy followed by chemotherapy or vice versa is considered the optimal therapy in North America while chemotherapy alone is the current standard in Europe.Regardless of the efforts in adjuvant and neoadjuvant improved therapy,the major goal to combat pancreatic cancer is to find diagnostic markers,identifying the disease in a pre-metastatic stage and making a curative treatment accessible to more patients.In this review,authors examined the different therapy options for advanced pancreatic patients in recent years and the future directions in adjuvant and neoadjuvant treatments for these patients.

    Purpose. Retrospective analysis of ten cases of germinoma of the central nervous system treated in Pitie Salpetriere Hospital, Paris. Patients and methods- - Ten male patients were treated from 1997 to 2005 for histologically verified primary seminoma of the central nervous system. The median age was 27 years (range 18 0 years). Our option for the treatment was the association of 3 cycles of neo-adjuvant chemotherapy (cisplatin and etoposide) to radiotherapy. Five patients received a craniospinal radiotherapy of 30 Gy (for one patient 36 Gy) followed by a tumoral boost from 20 to 24 Gy. For five patients, irradiated volume was limited to the tumour, total dose from 24 to 54 Gy (for three patients the total dose was from 24 to 30 Gy). Surgery was used for five patients, but only in one case was macroscopic complete. Results. Six patients were in situation of complete remission after neo-adjuvant chemotherapy. All the patients were in situation of complete remission after the irradiation. All the patients were alive free of disease with a median follow-up 46 months (range 13 0 months). Conclusion. In spite of the fact that the intracranial germinal tumours are not the subject of a consensual treatment strategy, this retrospective analysis pleads in favour of chemotherapy followed by limited dose and volume irradiation.

    Mutations in the Family with sequence similarity (FAM) 20 gene family are associated with mineralized tissue phenotypes in humans. Among these genes, FAM20A mutations are associated with Amelogenesis Imperfecta (AI) with gingival hyperplasia and nephrocalcinosis, while FAM20C mutations cause Raine syndrome, exhibiting bone and craniofacial/dental abnormalities. Although it has been demonstrated that Raine syndrome associated-FAM20C mutants prevented FAM20C kinase activity and secretion, overexpression of the catalytically inactive D478A FAM20C mutant was detected in both cell extracts and the media. This suggests that FAM20C secretion doesn’t require its kinase activity, and that another molecule(s) may control the secretion. In this study, we found that extracellular FAM20C localization was increased when wild-type (WT), but not AI-forms of FAM20A was co-transfected. On the other hand, extracellular FAM20C was absent in the conditioned media of mouse embryonic fibroblasts (MEFs) derived from Fam20a knock-out (KO) mouse, while it was detected in the media from WT MEFs. We also showed that cells with the conditioned media of Fam20a WT MEFs mineralized, but those with the conditioned media of KO MEFs failed to mineralize in vitro. Our data thus demonstrate that FAM20A controls FAM20C localization that may assist in the extracellular function of FAM20C in mineralized tissues. PMID:27292199

    The FAM20 family of secreted proteins consists of three members (FAM20A, FAM20B, and FAM20C) recently linked to developmental disorders suggesting roles for FAM20 proteins in modulating biomineralization processes. The authors report here findings in knockout mice having null mutations affecting each of the three FAM20 proteins. Both Fam20a and Fam20c null mice survived to adulthood and showed biomineralization defects. Fam20b (-/-) embryos showed severe stunting and increased mortality at E13.5, although early lethality precluded detailed investigations. Physiologic calcification or biomineralization of extracellular matrices is a normal process in the development and functioning of various tissues (eg, bones and teeth). The lesions that developed in teeth, bones, or blood vessels after functional deletion of either Fam20a or Fam20c support a significant role for their encoded proteins in modulating biomineralization processes. Severe amelogenesis imperfecta (AI) was present in both Fam20a and Fam20c null mice. In addition, Fam20a (-/-) mice developed disseminated calcifications of muscular arteries and intrapulmonary calcifications, similar to those of fetuin-A deficient mice, although they were normocalcemic and normophosphatemic, with normal dentin and bone. Fam20a gene expression was detected in ameloblasts, odontoblasts, and the parathyroid gland, with local and systemic effects suggesting both local and/or systemic effects for FAM20A. In contrast, Fam20c (-/-) mice lacked ectopic calcifications but were severely hypophosphatemic and developed notable lesions in both dentin and bone to accompany the AI. The bone and dentin lesions, plus the marked hypophosphatemia and elevated serum alkaline phosphatase and FGF23 levels, are indicative of autosomal recessive hypophosphatemic rickets/osteomalacia in Fam20c (-/-) mice.

    Breast cancer is the most frequent neoplasm affecting women worldwide. Some of the recommended treatments involve chemotherapy whose toxic effects include leukopenia and neutropenia. This study assessed the effectiveness of Uncaria tomentosa (Ut) in reducing the adverse effects of chemotherapy through a randomized clinical trial. Patients with Invasive Ductal Carcinoma-Stage II, who underwent a treatment regimen known as FAC (Fluorouracil, Doxorubicin, Cyclophosphamide), were divided into two groups: the UtCa received chemotherapy plus 300 mg dry Ut extract per day and the Ca group that only received chemotherapy and served as the control experiment. Blood samples were collected before each one of the six chemotherapy cycles and blood counts, immunological parameters, antioxidant enzymes, and oxidative stress were analyzed. Uncaria tomentosa reduced the neutropenia caused by chemotherapy and was also able to restore cellular DNA damage. We concluded that Ut is an effective adjuvant treatment for breast cancer.

This study assessed the effectiveness of Uncaria tomentosa (Ut in reducing the adverse effects of chemotherapy through a randomized clinical trial. Patients with Invasive Ductal Carcinoma—Stage II, who underwent a treatment regimen known as FAC (Fluorouracil, Doxorubicin, Cyclophosphamide, were divided into two groups: the UtCa received chemotherapy plus 300 mg dry Ut extract per day and the Ca group that only received chemotherapy and served as the control experiment. Blood samples were collected before each one of the six chemotherapy cycles and blood counts, immunological parameters, antioxidant enzymes, and oxidative stress were analyzed. Uncaria tomentosa reduced the neutropenia caused by chemotherapy and was also able to restore cellular DNA damage. We concluded that Ut is an effective adjuvant treatment for breast cancer.

    Objective To observe the long-term psychological effect and impact on the application of dexamethasone duing adjuvant chemotherapy on quality of life breast cancer patients. Methods 203 breast cancer patients were selected, who underwent chemotherapy without relapse and transfer during October 2010 to October 2012. All the patients underwent AC sequential T plan or TH chemotherapy ( A:Doxorubicin, C:Cyclophosphamide, T:Docetaxel, H:Trastuzumab) , and were given 24 mg dexamethasone before chemotherapy 1 d, oral twice a day, use of 2 d continually, four cycles in total. Hormone-related adverse reactions 3 years after chemotherapy, and 3 years before chemotherapy were recorded and QOL, SAS, SDS questionnaires were used to assess the impact of dexamethasone on quality of life and psychological aspects of long-term ad-verse effects. Results In the group of systemic chemotherapy for 3 years, 192 cases presented different degrees of osteoporo-sis, central obesity, moon face and the other hormone-related adverse reactions. Following 3 years of systemic chemotherapy, the scores of emotional functioning, fatigue, loss of appetite, sleep disturbances were significantly higher than that before treat-ment (P<0. 05), SAS and SDS scores were similar to that of emotional functioning, fatigue(P=0. 023; P=0. 037), and major psychological effect of patients was the result of adverse reaction form dexamethasone. Conclusion The application of dexamethasone in breast cancer patients during adjuvant chemotherapy can reduce chemotherapy-related adverse reactions, but may lead to different levels of hormone-related adverse reactions after two months, with long-term psychological effects, which will cause psychological changes, and reduce the quality of life of breast cancer patients.%目的:观察乳腺癌辅助化疗期间应用地塞米松对患者远期生活质量及心理的影响。方法收集我院2010年10月—2012年10月完成系统辅助化疗后至今未

    Full Text Available We present the case of a congenital localised sacrococcygeal primitive neuroectodermal tumor treated aggressively with surgical resection and modified age-appropriate adjuvant chemotherapy. The conventional combination chemotherapy of vincristine, adriamycin, cyclophosphamide, ifosfamide and etoposide was modified to a regimen including vincristine, adriamicin, cyclophosphamide and actinomycin in order to minimise the predicted toxicity in this age group. Adjuvant "induction" chemotherapy commenced at 4 weeks of age and consisted of four cycles of vincristine, adriamycin and cyclophosphamide at 50%, 75%, 75% and 100% of recommended doses (vincristine 0.05 mg/kg, adriamycin 0.83 mg/kg daily × 2, cyclophosphamide 40 mg/kg at 3-weekly intervals. This was followed by four cycles of "maintenance" chemotherapy with vincristine (0.025 mg/kg, actinomycin (0.025 mg/kg and cyclophosphamide (36 mg/kg at full recommended doses. Cardioxane at a dose of 16.6 mg/kg was infused immediately prior to the adriamycin. Our patient is thriving at 19 months out from end of treatment.

    Purpose: Long-term (LT) androgen suppression (AS) with radiation therapy (RT) is a standard treatment of high-risk, localized prostate cancer (PCa). Radiation Therapy Oncology Group 9902 was a randomized trial testing the hypothesis that adjuvant combination chemotherapy (CT) with paclitaxel, estramustine, and oral etoposide plus LT AS plus RT would improve overall survival (OS). Methods and Materials: Patients with high-risk PCa (prostate-specific antigen 20-100 ng/mL and Gleason score [GS] ≥7 or clinical stage ≥T2 and GS ≥8) were randomized to RT and AS (AS + RT) alone or with adjuvant CT (AS + RT + CT). CT was given as four 21-day cycles, delivered beginning 28 days after 70.2 Gy of RT. AS was given as luteinizing hormone-releasing hormone for 24 months, beginning 2 months before RT plus an oral antiandrogen for 4 months before and during RT. The study was designed based on a 6% improvement in OS from 79% to 85% at 5 years, with 90% power and a 2-sided alpha of 0.05. Results: A total of 397 patients (380 eligible) were randomized. The patients had high-risk PCa, 68% with GS 8 to 10 and 34% T3 to T4 tumors, and median prostate-specific antigen of 22.6 ng/mL. The median follow-up period was 9.2 years. The trial closed early because of excess thromboembolic toxicity in the CT arm. The 10-year results for all randomized patients revealed no significant difference between the AS + RT and AS + RT + CT arms in OS (65% vs 63%; P=.81), biochemical failure (58% vs 54%; P=.82), local progression (11% vs 7%; P=.09), distant metastases (16% vs 14%; P=.42), or disease-free survival (22% vs 26%; P=.61). Conclusions: NRG Oncology RTOG 9902 showed no significant differences in OS, biochemical failure, local progression, distant metastases, or disease-free survival with the addition of adjuvant CT to LT AS + RT. The trial results provide valuable data regarding the natural history of high-risk PCa treated with LT AS + RT and have implications for

    younger. The aim of this study was to investigate the safety and tolerance with non-anthracyclin regimen as adjuvant chemotherapy in elderly breast cancer patients. Methods:From Nov. 2008 to Jan. 2012, 56 patients (≥65 years) after surgical excision were enrolled into this study. The patients were divided into two groups:TC and PC groups. Each patient received 4 or 6 cycles of chemotherapy of PC (175 and 600 mg/m2, respectively;n=21) or TC (75 and 600 mg/m2, respectively;n=35), administered intravenously every 3 weeks, as adjuvant chemotherapy. Radiation therapy (as indicated) and endocrine therapy, for patients with hormone receptor-positive disease, were administered after completion of chemotherapy. Results: In this study, 50 patients completed chemotherapy as plan, the proportion of two groups were above 90%. After a median follow-up of 33 months, the median disease-free survival(DFS) and overall survival(OS) were not reached. The relapse-free rate and survival rate were 89.5%and 100%in the PC regime group, which were 90.3%and 96.8%in the TC regime group. Major toxicities included:neutropenia, leucopenia, alopecia, nausea, vomiting and various degree of peripheral neuropathy. The incidence of gradeⅢ-Ⅳneutropenia was 76.2%in PC group vs 48.6%in TC group (P=0.044). The most common cause for withdrawing from treatment was to be unable to tolerate the adverse effects. Conclusion:Adjuvant chemotherapy with paclitaxel and cyclophosphamide is safe, tolerable and promising for elderly breast cancer patients.

    The primary objective was to compare the 3-year survival of rectal cancer patients randomised postoperatively to irinotecan (IRI), Leucovorin (LV) and bolus 5-fluorouracil (5FU) or LV-bolus 5FU with radiotherapy. Secondary objectives included disease-free survival, local relapse and toxicity. The study included 321 eligible patients. The treatment consisted of weekly administration of IRI 80 mg/m(2) intravenously (IV), LV 200 mg/m(2) and 5FU 450 mg/m(2) bolus (arm A) versus LV 200 mg/m(2) and 5FU 450 mg/m(2) IV bolus (arm B). One cycle included four infusions and treatment was continued for a total of six cycles. The first cycle was followed by pelvic irradiation plus 5FU. There were no differences between the arms in 3-year overall, disease-free and local relapse-free survival. Grades 3 and 4 toxicity was similar in both the arms with the exception of leucopaenia, neutropaenia and alopecia, which were higher in the IRI arm. IRI added to adjuvant radiochemotherapy with LV and bolus 5FU was not shown to improve survival, whereas the incidence of severe leucopaenia was significantly higher in the IRI arm.

    For early stage breast cancer, wide local excision and post-operative whole breast irradiation is a standard treatment. If adjuvant chemotherapy is recommended, radiation is usually given after completion of chemotherapy. In recent years, accelerated partial breast irradiation (APBI) with balloon-cathetered based brachytherapy has become an option for selected patients. For these patients, adjuvant chemotherapy would have to be administered after radiation. The sequence of treatment with radiation followed by chemotherapy results in increased risk of radiation recall reaction (RRD) in these patients. Docetaxel is becoming a more commonly used drug as adjuvant treatment for breast cancer. Here we report a case of docetaxel induced RRD after APBI with balloon-cathetered based brachytherapy. Such reaction would have an adverse impact on the cosmetic outcome and quality of life of the patient. For patients who develop an intense skin reaction after the administration of docetaxel following APBI, RRD should be considered in the differential diagnosis.

    Objective To explore the effects of adjuvant chemotherapy combined with Kang'ai injection on the expression of serum VEGF in patients with advanced non-small cell lung cancer. Methods Forty-six patients with advanced non-small cell lung cancer were randomly divided equally into two groups. Patients in experimental group were treated with gemcitabine and cisplatin chemotherapy regimen(GP)combined with Kang'ai injection, while patients in the control were just treated with GP regimen chemotherapy. The expression levels of serum vascular endothelial growth factor(sVEGF) were measured by ELISA before and after the treatment,respectively. Results The sVEGF levels of all patients with advanced NSCLC were obviously higher than that of health controls(P<0. 05). And the level of sVEGF in squamous cell cancer group was higher than that in adenocarcinoma, large cell carcinoma or adenosquamous carcinoma group, respectively(P<0. 05),while there was no significant difference between the latter 3 groups(P>0. 05). Compared the well differentiated group, the sVEGF level of moderately and poorly defferentiated group was increased with no significance(P>0. 05). The sVEGF level was obviously decreased in two groups after the treatments(P<0. 05). Furthermore, the sVEGF level was significantly decreased combination therapy group than that in chemotherapy group(P<0. 05). Conclusion Kang'ai injection might decrease the expression of serum VEGF in patients with advanced non-small cell lung cancer which suppressed neovascularization. Serum VEGF could be a biomarker for lung cancer diagnosis and therapeutic effect of chemotherapy or biotherapy.%目的 探讨康艾注射液辅助化疗对晚期非小细胞肺癌患者血清VEGF(sVEGF)表达的干预作用.方法 将入组的46例晚期非小细胞肺癌患者随机分为实验组(康艾注射液联合化疗组,23例)和对照组(单纯化疗组23例),应用酶联免疫吸附法(ELISA)检测患者治疗前后sVEGF表

    2008-01-01

    BACKGROUND:Pancreatic cancer is an aggressive malignancy with a dismal prognosis. Radical surgery provides the only chance for a cure with a 5-year survival rate of 7%-25%. An effective adjuvant therapy is urgently needed to improve the surgical outcome. This review describes the current status of adjuvant therapy for pancreatic cancer, and highlights its controversies. DATA SOURCES:A Medline database search was performed to identify relevant articles using the keywords"pancreatic neoplasm", and"adjuvant therapy". Additional papers were identiifed by a manual search of the references from the key articles. RESULTS:Eight prospective randomized controlled trials (RCTs) on the use of adjuvant chemotherapy and chemoradiation for pancreatic cancer could be identiifed. The results for adjuvant regimens based on systemic 5-lfuorouracil with or without external radiotherapy were conlficting. The recent two RCTs on gemcitabine based regimen gave promising results. CONCLUSIONS:Based on the available data, no standard adjuvant therapy for pancreatic cancer can be established yet. The best adjuvant regimen remains to be determined in large-scale RCTs. Future trials should use a gemcitabine based regimen.

    Full Text Available It has been demonstrated that 1,25-dihydroxyvitamin D3 (1,25D and some of its analogues have antitumor activity. 1,25D labeled with deuterium (26,26,26,27,27,27-hexadeuterated 1a,25-dihydroxyvitamin D3, or 1,25D-d6 is commonly used as internal standard for 1,25D liquid chromatography-mass spectrometry (LC-MS quantification. In the present study using human breast cancer cell lines, the biological activity of 1,25D-d6 administered alone and in combination with two commonly used antineoplastic agents, 5-fluorouracil and etoposide, was evaluated. Using an MTT assay, flow cytometry, and western blots, our data demonstrated that 1,25D-d6 has effects similar to the natural hormone on cell proliferation, cell cycle, and apoptosis. Furthermore, the combination of 1,25D-d6 and etoposide enhances the antitumoral effects of both compounds. Interestingly, the antitumoral effect is higher in the more aggressive MDA-MB-231 breast cancer cell line. Our data indicate that 1,25D-d6 administered alone or in combination with chemotherapy could be a good experimental method for accurately quantifying active 1,25D levels in cultures or in biological fluids, on both in vitro breast cancer cell lines and in vivo animal experimental models.

    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.

    The aim of this study was to determine the utilization rates and impact of adjuvant therapy on overall survival (OS) for anaplastic oligodendroglioma (AO). Data were extracted from the National Cancer Data Base (NCDB). Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 1692 patients with AO who underwent surgery were identified. 945 (55.9 %) received adjuvant radiotherapy with concomitant chemotherapy (chemoRT), 102 (6.0 %) adjuvant radiotherapy (RT) sequentially followed by chemotherapy, 244 (14.4 %) adjuvant RT alone, and 401 (23.7 %) received no adjuvant therapy. Patients were more likely to receive adjuvant chemoRT if they were diagnosed in 2009-2013 vs. 2004-2008 (p 70 vs. <70 (p = 0.018), had private insurance vs. Medicaid vs. no insurance (p < 0.001), or had median income ≥$63,000 vs. <$63,000 (p = 0.014). Those who received adjuvant chemoRT (concomitant or sequential) had significantly better 5-year OS than those who received adjuvant RT alone or no adjuvant therapy (59.8 % vs. 65.0 % vs. 44.9 % vs. 45.6 %, p < 0.001). This significant 5-year OS benefit was also observed regardless of age. There was no difference in OS when comparing concomitant chemoRT to sequential RT and chemotherapy (p = 0.481). On multivariate analysis, receipt of adjuvant chemoRT (concomitant or sequential) remained an independent prognostic factor for improved OS. Adjuvant chemoRT (concomitant or sequential) is an independent prognostic factor for improved OS in anaplastic oligodendroglioma and should be considered for all clinically suitable patients who have undergone surgery for the disease.

    Full Text Available The management of retinoblastoma (RB has dramatically changed over the past two decades from previous radiotherapy methods to current chemotherapy strategies. RB is a remarkably chemotherapy-sensitive tumor. Chemotherapy is currently used as a first-line approach for children with this malignancy and can be delivered by intravenous, intra-arterial, periocular, and intravitreal routes. The choice of route for chemotherapy administration depends upon the tumor laterality and tumor staging. Intravenous chemotherapy (IVC is used most often in bilateral cases, orbital RB, and as an adjuvant treatment in high-risk RB. Intra-arterial chemotherapy (IAC is used in cases with group C or D RB and selected cases of group E tumor. Periocular chemotherapy is used as an adjunct treatment in eyes with group D and E RB and those with persistent/recurrent vitreous seeds. Intravitreal chemotherapy is reserved for eyes with persistent/recurrent vitreous seeds. In this review, we describe the various forms of chemotherapy used in the management of RB. A database search was performed on PubMed, using the terms "RB," and "treatment," "chemotherapy," "systemic chemotherapy," "IVC," "IAC," "periocular chemotherapy," or "intravitreal chemotherapy." Relevant English language articles were extracted, reviewed, and referenced appropriately.

  19. Vaccines, adjuvants and autoimmunity.

    Science.gov (United States)

    Guimarães, Luísa Eça; Baker, Britain; Perricone, Carlo; Shoenfeld, Yehuda

    2015-10-01

    Vaccines and autoimmunity are linked fields. Vaccine efficacy is based on whether host immune response against an antigen can elicit a memory T-cell response over time. Although the described side effects thus far have been mostly transient and acute, vaccines are able to elicit the immune system towards an autoimmune reaction. The diagnosis of a definite autoimmune disease and the occurrence of fatal outcome post-vaccination have been less frequently reported. Since vaccines are given to previously healthy hosts, who may have never developed the disease had they not been immunized, adverse events should be carefully accessed and evaluated even if they represent a limited number of occurrences. In this review of the literature, there is evidence of vaccine-induced autoimmunity and adjuvant-induced autoimmunity in both experimental models as well as human patients. Adjuvants and infectious agents may exert their immune-enhancing effects through various functional activities, encompassed by the adjuvant effect. These mechanisms are shared by different conditions triggered by adjuvants leading to the autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome). In conclusion, there are several case reports of autoimmune diseases following vaccines, however, due to the limited number of cases, the different classifications of symptoms and the long latency period of the diseases, every attempt for an epidemiological study has so far failed to deliver a connection. Despite this, efforts to unveil the connection between the triggering of the immune system by adjuvants and the development of autoimmune conditions should be undertaken. Vaccinomics is a field that may bring to light novel customized, personalized treatment approaches in the future.

    The authors reviewed 24 cerebellar medulloblastoma patients treated at Keio University to determine usefulness of combined chemotherapy including platinum derivatives (cisplatin, carboplatin) as the induction and maintenance treatment. All patients underwent radical surgery and craniospinal irradiation. Ten received adjuvant chemotherapy other than platinum derivatives (mainly with nitrosourea compounds), five were treated by induction and maintenance chemotherapy including platinum derivatives, and nine patients did not undergo chemotherapy. The progression-free survival rate of patients treated with platinum derivatives was better than that of patients treated with other modes of chemotherapy and also that of patients who did not receive chemotherapy. The results were especially good in the case of four patients treated with maintenance chemotherapy consisting of carboplatin and etoposide, two of whom had been free from relapse beyond the risk period of Collins. The occurrences of toxicity in maintenance chemotherapy with carboplatin and etoposide were limited to transient leucopenia. The present study indicates combined chemotherapy including platinum derivatives benefits patients with medulloblastoma, and could be useful, especially as maintenance treatment. (author)

    Objective To examine the relationship between the adjuvant chemotherapy-induced leucopenia (CIL) and curative effects in high risk breast cancer patients. Methods 106 patients were treated with FAC-D regimen. According to the degree of CIL, the patients were classified into three groups:no reduction of leucopenia as control group;Ⅰ~Ⅱleucopenia as the observation group 1;Ⅲ~Ⅳleucopenia as the observation group 2. The disease-free survival (DFS) and overall survival (OS) in three groups were compared and the relationship between CIL risk factors and chemotherapy curative effects were analyzed. Results CIL in observation group 1 and observation group 2 was 51.0%and 26.5%respectively. The disease-free survival rate was 56.5%, 78.8%and 67.9%respectively for the control group, observation group 1 and observation group 2. The overall survival rate was 70.8%, 88.9%and 82.1%respectively in the control group, observation group 1 and observa-tion group 2. Compared with the other two groups, DFS and OS were obviously higher in observation group 1 (P<0.05). It was positively correlated between the degree of CIL and the DFS and OS (P<0.05). It was showed that the number and size of transfer lymph node, foundation of white blood cells, gastrointestinal reaction were the risk factors of chemotherapy related leucopenia in breast cancer;while the age, wound healing, ER state had nothing to do with it. Conclusion The risk factors of chemotherapy induced leucopenia in breast cancer include the number and size of transfer lymph node, foundation of white blood cells, gastrointestinal reaction. Chemotherapy-related leucopenia may be taken as an indicator for prognosis of patients with breast cancer after chemotherapy.%  目的评价高危乳腺癌术后化疗相关性白细胞减少与其预后之间的关系.方法对106例高危乳腺癌患者采用FAC-D方案行术后辅助化疗,根据化疗相关性白细胞减少程度进行分组:无白细胞减少的患者为对

  3. FAM5C contributes to aggressive periodontitis.

    Directory of Open Access Journals (Sweden)

    Flavia M Carvalho

    Full Text Available Aggressive periodontitis is characterized by a rapid and severe periodontal destruction in young systemically healthy subjects. A greater prevalence is reported in Africans and African descendent groups than in Caucasians and Hispanics. We first fine mapped the interval 1q24.2 to 1q31.3 suggested as containing an aggressive periodontitis locus. Three hundred and eighty-nine subjects from 55 pedigrees were studied. Saliva samples were collected from all subjects, and DNA was extracted. Twenty-one single nucleotide polymorphisms were selected and analyzed by standard polymerase chain reaction using TaqMan chemistry. Non-parametric linkage and transmission distortion analyses were performed. Although linkage results were negative, statistically significant association between two markers, rs1935881 and rs1342913, in the FAM5C gene and aggressive periodontitis (p = 0.03 was found. Haplotype analysis showed an association between aggressive periodontitis and the haplotype A-G (rs1935881-rs1342913; p = 0.009. Sequence analysis of FAM5C coding regions did not disclose any mutations, but two variants in conserved intronic regions of FAM5C, rs57694932 and rs10494634, were found. However, these two variants are not associated with aggressive periodontitis. Secondly, we investigated the pattern of FAM5C expression in aggressive periodontitis lesions and its possible correlations with inflammatory/immunological factors and pathogens commonly associated with periodontal diseases. FAM5C mRNA expression was significantly higher in diseased versus healthy sites, and was found to be correlated to the IL-1beta, IL-17A, IL-4 and RANKL mRNA levels. No correlations were found between FAM5C levels and the presence and load of red complex periodontopathogens or Aggregatibacter actinomycetemcomitans. This study provides evidence that FAM5C contributes to aggressive periodontitis.

    Chemotherapy is one of main treatments for nasopharyngeal carcinoma (NPC) except radiation therapy. Improving and optimizing chemotherapeutic regimen are helpful to improve the therapeutic effects and reduce side effects. At present, concurrent chemoradiotherapy still is the standard treatment for advanced nasopharyngeal carcinoma. Induced chemotherapy has been shown superiority, but the effect of adjuvant chemotherapy needs further study. This paper analyzed the superior and inferior, effect and side effect of all kinds of chemotherapeutic methods or scheme including induced chemotherapy,concurrent chemotherapy, adjuvant chemotherapy and palliative chemotherapy and introduced simply the mechanism and clinical effect of new drugs of anticancer. It was hoped to offer some reference for the selection of chemotherapy for NPC.

    Several attempts have been made to improve the survival rates of breast cancer patients. The benefit of adjuvant chemotherapy was clearly shown, but the absolute difference of 2% to 11% in overall survival, depending on the patient group, is disappointingly small. In particular, high-risk patients, such as those with > or = 10 involved lymph nodes, extracapsular spread, or vascular invasion, still have an excessive risk of recurrence even after standard adjuvant chemotherapy. To increase the survival rates after adjuvant therapy, new chemotherapeutic agents and new strategies of application are currently being evaluated in clinical trials. Chemotherapy with cyclophosphamide (Cytoxan, Neosar), methotrexate, and fluorouracil (CMF) seems to be safe and effective in patients with breast cancer. In addition, in metastatic patients, dose-intensified chemotherapy is being investigated. The introduction of epirubicin (Ellence), an agent less cardiotoxic and equally active compared to doxorubicin, enabled the escalation of anthracyclines in adjuvant therapy without serious cardiotoxic effects. The combination of dose-intensified chemotherapy and sequential application in the treatment of breast cancer is reviewed.

    Full Text Available Abstract Background Sulfotransferase 1A1 (SULT1A1 participates in the elimination of 4-hydroxy-tamoxifen (4-OH-TAM, which is one of the major active metabolites of tamoxifen (TAM. Homozygous SULT1A1 variant allele genotype has been associated with lower catalytic activity and thermostability of the enzyme. Previous clinical studies suggest that the SULT1A1 rs9282861 polymorphism may influence the survival of breast cancer patients treated with TAM in the adjuvant setting. We investigated the effect of rs9282861 genotypes on the survival of Finnish breast cancer patients treated with adjuvant chemotherapy or TAM. Methods The rs9282861 genotypes of 412 Finnish breast cancer patients with early breast cancer were identified by using PCR-RFLP method. Seventy six patients were treated with adjuvant cyclophosphamide based chemotherapy only, 65 patients received adjuvant TAM, and four patients were treated with both adjuvant chemotherapy and TAM. Overall long-term survival (OS, breast cancer specific survival (BCSS, and relapse-free survival (RFS by rs9282861 genotypes were evaluated by the Kaplan-Meier method and Cox regression analysis. Results The multivariate analysis of 145 patients receiving either adjuvant TAM or chemotherapy showed a statistically significantly improved OS in patients with the rs9282861 homozygous variant AA genotype (hazard ratio [HR] = 0.50, 95% confidence interval [CI] = 0.29-0.88, P = 0.015. In the separate analyses of patients receiving only chemotherapy or adjuvant TAM, there were no statistically significant differences in survival. Conclusions In this prospective study, we observed a previously unreported association between the SULT1A1 rs9282861 genotype and OS of breast cancer patients treated with adjuvant chemotherapy or TAM. This novel finding suggests that the rs9282861 polymorphism modifies the long-term clinical outcome of patients receiving adjuvant TAM or chemotherapy.

  7. Adjuvants for allergy vaccines.

    Moingeon, Philippe

    2012-10-01

    Allergen-specific immunotherapy is currently performed via either the subcutaneous or sublingual routes as a treatment for type I (IgE dependent) allergies. Aluminum hydroxide or calcium phosphate are broadly used as adjuvants for subcutaneous allergy vaccines, whereas commercial sublingual vaccines rely upon high doses of aqueous allergen extracts in the absence of any immunopotentiator. Adjuvants to be included in the future in products for allergen specific immunotherapy should ideally enhance Th1 and CD4+ regulatory T cell responses. Imunomodulators impacting dendritic or T cell functions to induce IL10, IL12 and IFNγ production are being investigated in preclinical allergy models. Such candidate adjuvants encompass synthetic or biological immunopotentiators such as glucocorticoids, 1,25-dihydroxy vitamin D3, selected probiotic strains (e.g., Lactobacillus and Bifidobacterium species) as well as TLR2 (Pam3CSK4), TLR4 (monophosphoryl lipid A, synthetic lipid A analogs) or TLR9 (CpGs) ligands. Furthermore, the use of vector systems such as mucoadhesive particules, virus-like particles or liposomes are being considered to enhance allergen uptake by tolerogenic antigen presenting cells present in mucosal tissues.

    Full Text Available Despite treatment with radical cystectomy and pelvic lymph node dissection, muscle invasive bladder cancer has a relapse rate of 50%. Patients can develop regionally advanced or metastatic disease that ultimately leads to death. The addition of neoadjuvant or adjuvant chemotherapy to reduce the risk of relapse and death has been extensively studied over the past two decades. Two contemporary trials coupled with a recent meta-analysis evaluating neoadjuvant chemotherapy demonstrated a modest but real improvement in overall survival. This has made neoadjuvant chemotherapy a standard of care. Clinical trials evaluating adjuvant chemotherapy in patients with high-risk disease have been plagued with statistical flaws and have, therefore, been unable to define the survival impact of this approach. It is hoped that ongoing adjuvant trials that are powered to detect small but meaningful clinical differences will clarify the benefit of chemotherapy after cystectomy. Since there are theoretical advantages and disadvantages to each of these approaches, both are widely used in North America. The evidence behind each approach and potential future developments in this field will be described.

    Full Text Available Background . Complementary and alternative medicine (CAM practices for cancer have become popular among oncology patients. An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

    Gliomas, the most common primary brain tumors, are diffusive and highly invasive. The standard treatment for brain tumors consists of a combination of surgery, radiation therapy and chemotherapy. Over the past few years, mathematical models have been applied to study untreated and treated brain tumors. In an effort to improve treatment strategies, we consider a simple spatio-temporal mathematical model, based on proliferation and diffusion, that incorporates the effects of radiotherapeutic and chemotherapeutic treatments. We study the effects of different schedules of radiation therapy, including fractionated and hyperfractionated external beam radiotherapy, using a generalized linear quadratic (LQ) model. The results are compared with published clinical data. We also discuss the results for combination therapy (radiotherapy plus temozolomide, a new chemotherapy agent), as proposed in recent clinical trials. We use the model to predict optimal sequencing of the postoperative (combination of radiotherapy and adjuvant, neo-adjuvant or concurrent chemotherapy) treatments for brain tumors.

    2011-01-01

    The role for adjuvants in human vaccines has been a matter of vigorous scientific debate, with the field hindered by the fact that for over 80 years, aluminum salts were the only adjuvants approved for human use. To this day, alum-based adjuvants, alone or combined with additional immune activators, remain the only adjuvants approved for use in the USA. This situation has not been helped by the fact that the mechanism of action of most adjuvants has been poorly understood. A relative lack of resources and funding for adjuvant development has only helped to maintain alum’s relative monopoly. To seriously challenge alum’s supremacy a new adjuvant has many major hurdles to overcome, not least being alum’s simplicity, tolerability, safety record and minimal cost. Carbohydrate structures play critical roles in immune system function and carbohydrates also have the virtue of a strong safety and tolerability record. A number of carbohydrate compounds from plant, bacterial, yeast and synthetic sources have emerged as promising vaccine adjuvant candidates. Carbohydrates are readily biodegradable and therefore unlikely to cause problems of long-term tissue deposits seen with alum adjuvants. Above all, the Holy Grail of human adjuvant development is to identify a compound that combines potent vaccine enhancement with maximum tolerability and safety. This has proved to be a tough challenge for many adjuvant contenders. Nevertheless, carbohydrate-based compounds have many favorable properties that could place them in a unique position to challenge alum’s monopoly over human vaccine usage. PMID:21506649

    Full Text Available With an incidence that is increasing at 2–5% per year, cutaneous melanoma is an international scourge that disproportionately targets young individuals. Despite much research, the treatment of advanced disease is still quite challenging. Immunotherapy with high-dose interferon-α2b or interleukin-2 benefits a select group of patients in the adjuvant and metastatic settings, respectively, with significant attendant toxicity. Advances in the biology of malignant melanoma and the role of immunomodulatory therapy have produced advances that have stunned the field. In this paper, we review the data for the use of interferon-α2b in various dosing ranges, vaccine therapy, and the role of radiotherapy in the adjuvant setting for malignant melanoma. Recent trials in the metastatic setting using anticytoxic T-lymphocyte antigen-4 (anti-CTLA-4 monoclonal antibody therapy and BRAF inhibitor therapy have demonstrated clear benefit with prolongation of survival. Trials investigating combinations of these novel agents with existing immunomodulators are at present underway.

    Full Text Available Abstract Background Studies have shown that surgery alone is less than satisfactory in the management of early gastric cancer, with cure rates approaching 40%. The role of adjuvant therapy was indefinite until three large, randomized controlled trials showed the survival benefit of adjuvant therapy over surgery alone. Chemoradiation therapy has been criticized for its high toxicity. Methods 24 patients diagnosed between September 2001 and July 2007 were treated with adjuvant chemoradiation. 18 patients had the classical MacDonald regimen of 4500 cGy of XRT and chemotherapy with 5-fluorouracil (5FU and leucovorin, while chemotherapy consisted of 5FU/Cisplatin for 6 patients. Results This series consisted of non-metastatic patients, 17 females and 7 males with a median age of 62.5 years. 23 patients (96% had a performance status of 0 or 1. The full course of radiation therapy (4500 cGy was completed by 22 patients (91.7%. Only 7 patients (36.8% completed the total planned courses of chemotherapy. 2 local relapses (10%, 2 regional relapses (10% and 2 distant relapses (10% were recorded. Time to progression has not been reached. 9 patients (37.5% died during follow-up with a median overall survival of 75 months. Patients lost a mean of 4 Kgs during radiation therapy. We recorded 6 episodes of febrile neutropenia and the most frequent toxicity was gastro-intestinal in 17 patients (70.8% with 9 (36% patients suffering grade 3 or 4 toxicity and 5 patients (20% suffering from grade 3 or 4 neutropenia. 4 (17% patients required total parenteral nutrition for a mean duration of 20 days. 4 patients suffered septic shock (17% and 1 patient developed a deep venous thrombosis and a pulmonary embolus. Conclusions Adjuvant chemo-radiation for gastric cancer is a standard at our institution and has resulted in few relapses and an interesting median survival. Toxicity rates were serious and this remains a harsh regimen with only 36.8% of patients completing the

    The management of colon and rectal cancer has changed dramatically over the last 25 years. The use of adjuvant therapies has become standard practice in locally advanced (stage Ⅲ and selected stage Ⅱ) colorectal cancer. Improved surgical techniques, chemotherapeutics and radiotherapy are resulting in higher cure rates and the development of agents targeting proliferative and angiogenic pathways offer further promise. Here we explore risk factors for local and distant recurrence after resection of colon and rectal cancer, and the role of adjuvant treatments. Discussion will focus on the evidence base for adjuvant therapies utilised in colorectal cancer, and the treatment of sub-groups such as the elderly and stage Ⅱ disease. The role of adjuvant radiotherapy in rectal cancer in reduction of recurrence will be explored and the role and optimal methods for surveillance post-curative resection with or without adjuvant therapy will also be addressed.

    FAM20C is an evolutionarily reserved molecule highly expressed in mineralized tissues. Previously we demonstrated that Sox2-Cre;Fam20C(fl/fl) mice, in which Fam20C was ubiquitously inactivated, had dentin and enamel defects as well as hypophosphatemic rickets. We also showed that K14-Cre;Fam20C(fl/fl) mice, in which Fam20C was specifically inactivated in the epithelium, had enamel defects but lacked hypophosphatemia and defects in the bone and dentin. These results indicated that the enamel defects in the Sox2-Cre;Fam20C(fl/fl) mice were independent of dentin defects and hypophosphatemia. To determine if the dentin defects in the Sox2-Cre;Fam20C(fl/fl) mice were associated with the enamel defects and hypophosphatemia, we crossed Fam20C(fl/fl) mice with Wnt1-Cre and Osr2-Cre transgenic mice to inactivate Fam20C in the craniofacial mesenchymal cells that form dentin and alveolar bone. The resulting Wnt1-Cre;Fam20C(fl/fl) and Osr2-Cre;Fam20C(fl/fl) mice showed remarkable dentin and alveolar bone defects, while their enamel did not show apparent defects. The serum FGF23 levels in these mice were higher than normal but lower than those in the Sox2-Cre;Fam20C(fl/fl) mice; they developed a mild type of hypophosphatemia that did not cause major defects in long bones. These results indicate that the dentin defects in the Sox2-Cre;Fam20C(fl/fl) mice were independent of the enamel defects.

    Background There is wide variation in the application of adjuvant chemotherapy in early-stage epithelial ovarian cancer. Our aim was to assess differences in health-related quality of life (hrqol) between patients with early-stage ovarian cancer who did or did not receive chemotherapy as adjuvant treatment. Methods All patients diagnosed with early-stage ovarian cancer between 2000 and 2010 within the population-based Eindhoven Cancer Registry (n = 191) were enrolled in this study. Patients were requested to complete questionnaires, including the cancer-specific (qlq-C30) and ovarian cancer-specific (qlq-OV28) quality of life measures from the European Organisation for Research and Treatment of Cancer. Primary outcome measures were the generic-and cancer-specific domain scores for hrqol in ovarian cancer survivors. Results Of the 107 patients (56%) who returned the questionnaires, 57 (53.3%) had received adjuvant chemotherapy and 50 (46.7%) had been treated with surgery alone. Significant differences in hrqol between those groups were found in the symptom scales for peripheral neuropathy, attitude toward sickness, and financial situation, with worse scores in the chemotherapy group. Conclusions Results of our study show that patients who receive adjuvant chemotherapy have a significantly worse score for 3 aspects of hrqol. Efforts should be made to reduce use of adjuvant chemotherapy in early-stage ovarian cancer. Moreover, preventive strategies to improve long-term quality of life for those who need adjuvant chemotherapy should be explored. PMID:28050144

    trastuzumab (Herceptin administration, there has been no published case of radiation recall reaction associated with trastuzumab. This case describes a clinical presentation consistent with a radiation recall reaction following administration of adjuvant trastuzumab after neoadjuvant FEC-D chemotherapy and locoregional radiotherapy for HER2-positive, locally advanced breast cancer in a premenopausal woman. Although the mechanism and etiology of radiation recall dermatitis remain unclear, this case raises further hypotheses regarding a possible drug dose-dependence and possible predisposing risk factor for the development of radiation recall reactions.

    Previously, we showed that Sox2-Cre;Fam20C(fl/fl) mice in which Fam20C was ubiquitously inactivated had severe defects in dentin, enamel, and bone, along with hypophosphatemia. It remains to be determined if the enamel defects in the mice with universal inactivation of Family with sequence similarity 20-C (FAM20C) were associated with the dentin defects and whether hypophosphatemia in the knockout mice contributed to the enamel defects. In this study, we crossed Fam20C(fl/fl) mice with keratin 14-Cre (K14-Cre) transgenic mice to specifically inactivate Fam20C in the epithelial cells, including the dental epithelial cells that are responsible for forming tooth enamel. X-ray, backscattered scanning electron microscopic, and histological analyses showed that the K14-Cre;Fam20C(fl/fl) mice had severe enamel and ameloblast defects, while their dentin and alveolar bone were not significantly affected. Accordingly, serum biochemistry of the K14-Cre;Fam20C(fl/fl) mice showed normal phosphate and FGF23 levels in the circulation. Analysis of these data indicates that, while FAM20C is a molecule essential to amelogenesis, its inactivation in the dental epithelium does not significantly affect dentinogenesis. Hypophosphatemia makes no significant contribution to the enamel defects in the mice with the ubiquitous deletion of Fam20C.

    BACKGROUND: Following curative treatment for hepato-cellular carcinoma (HCC), 50%-90% of postoperative death is due to recurrent disease. Intra-hepatic recurrence is frequently the only site of recurrence. Thus, any neoadjuvant or adjuvant therapy, which can decrease or delay the incidence of intra-hepatic recurrence, or any cancer chemoprevention which can prevent a new HCC from developing in the liver remnant, will improve the results of liver resection. This article systematically reviewed the current evidence of neoadjuvant, adjuvant, and chemoprevention in partial hepatectomy of HCC. DATA SOURCES: Studies were identiifed by searching MEDLINE and PubMed databases for articles from January 1990 to November 2008 using the keywords"hepatocellular carcinoma", "hepatectomy", "adjuvant therapy", "neoadjuvant therapy", and "regional therapy". Additional papers and book chapters were identiifed by a manual search of the references from the key articles. RESULTS: Neoadjuvant transarterial chemoembolization or adjuvant regional transarterial chemotherapy± embolization+systemic chemotherapy did not add beneift. Both adjuvant transarterial radioembolization with 131I-lipiodol and adjuvant systemic interferon showed promising results. However, there were only a limited number of such studies.CONCLUSIONS: Further randomized controlled studies need to be carried out. Currently, there is no consensus on a standard neoadjuvant/adjuvant/chemoprevention therapy in partial hepatectomy for HCC.

    2006-10-01

    One of the most recent advances in the management of Her-2/neu positive breast cancer is the validation of a targeted therapy from bench to the clinic, particularly towards the adjuvant setting. The recommended dose of trastuzumab (Herceptin), a humanized monoclonal antibody targeting the HER-2 antigen, has been determined in phase I studies. In the metastatic patients two randomised trials have demonstrated its efficacy when associated to taxanes. In less than 10 years, trastuzumab became the standard of care in the adjuvant treatment of HER-2/neu positive breast cancer. In this setting, two combinations regimen with chemotherapy (concomitant or sequential) have been recently published. The concomitant schedule has been used in three studies (North American Group, BCIRG, FinHer), whereas in the Hera trial trastuzumab was started after the end of neo-adjuvant and adjuvant chemotherapy. In this article, the advantages and uncertainties on efficacy and toxicities of the trastuzumab administration modalities, associated or not to chemotherapy and radiation therapy, are discussed.

  16. Progress in systemic chemotherapy of primary breast cancer: an overview.

    Substantial progress has been made in the multidisciplinary management of primary breast cancer during the last 30 years. Adjuvant chemotherapy has been shown to significantly reduce the annual risk of cancer recurrence and mortality, and these effects persist even 15 years after diagnosis. Combination chemotherapy is superior to single-agent therapy and anthracycline-containing regimens. Those that combine an anthracycline with 5-fluorouracil and cyclophosphamide are more effective than regimens without an anthracycline. Six cycles of a single regimen appear to provide optimal benefit. Dose reductions below the standard range are associated with inferior results. Dose increases that require growth factor or hematopoietic stem cell support are under investigation; at this time, the existing results provide no compelling reason to use this strategy outside a clinical trial. Regimens using fixed crossover designs with two non-cross-resistant regimens are being evaluated. The addition of a taxane to anthracycline-containing regimens is currently under intense scrutiny, and preliminary analysis of the first three clinical trials has shown encouraging, albeit not compelling, results. For patients with estrogen receptor-positive breast cancer, the sequential administration of chemotherapy and 5 years of tamoxifen therapy provides additive benefits. No compelling evidence exists to combine ovarian ablation with chemotherapy. Most side effects and toxic effects are self-limited, although premature menopause requires monitoring and preventive interventions to preserve bone mineral density. The small risk of acute leukemia is of concern, and additional research to develop safer regimens is clearly indicated. The overall effect of optimal local/regional treatment combined with an anthracycline-containing adjuvant chemotherapy and a taxane (and, for patients with estrogen receptor-positive tumors, 5 years of tamoxifen therapy) is a greater than 50% reduction in annual risks of

    2015-01-01

    Breast cancer is the leading cause of cancer among women worldwide and the most common cancer in China. Many factors influence the treatment strategy for metastatic breast cancer (MBC). Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metastasis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combination agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel-bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and cetuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall survival with maintenance chemotherapy according to a Korean phase Ⅲ clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy (X-based X) appears favorable based on a series of domestic studies.

  3. How to define green adjuvants.

    Science.gov (United States)

    Beck, Bert; Steurbaut, Walter; Spanoghe, Pieter

    2012-08-01

    The concept 'green adjuvants' is difficult to define. This paper formulates an answer based on two approaches. Starting from the Organisation for Economic Cooperation and Development (OECD) definition for green chemistry, production-based and environmental-impact-based definitions for green adjuvants are proposed. According to the production-based approach, adjuvants are defined as green if they are manufactured using renewable raw materials as much as possible while making efficient use of energy, preferably renewable energy. According to the environmental impact approach, adjuvants are defined as green (1) if they have a low human and environmental impact, (2) if they do not increase active ingredient environmental mobility and/or toxicity to humans and non-target organisms, (3) if they do not increase the exposure to these active substances and (4) if they lower the impact of formulated pesticides by enhancing the performance of active ingredients, thus potentially lowering the required dosage of active ingredients. Based on both approaches, a tentative definition for 'green adjuvants' is given, and future research and legislation directions are set out.

    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.

    Full Text Available Abstract Background Despite major improvements in the perioperative outcome of pancreas surgery, the prognosis of pancreatic cancer after curative resection remains poor. Adjuvant chemotherapy increases disease-free and overall survival, but this treatment cannot be offered to a significant proportion of patients due to the surgical morbidity. In contrast, almost all patients can receive (neoadjuvant chemotherapy before surgery. This treatment is safe and effective, and has resulted in a median survival of 26.5 months in a recent phase II trial. Moreover, neoadjuvant chemotherapy improves the nutritional status of patients with pancreatic cancer. This multicenter phase III trial (NEOPAC has been designed to explore the efficacy of neoadjuvant chemotherapy. Methods/Design This is a prospective randomized phase III trial. Patients with resectable cytologically proven adenocarcinoma of the pancreatic head are eligible for this study. All patients must be at least 18 years old and must provide written informed consent. An infiltration of the superior mesenteric vein > 180° or major visceral arteries are considered exclusion criteria. Eligible patients will be randomized to surgery followed by adjuvant gemcitabine (1000 mg/m2 for 6 months or neoadjuvant chemotherapy (gemcitabine 1000 mg/m2, oxaliplatin 100 mg/m2 followed by surgery and the same adjuvant treatment. Neoadjuvant chemotherapy is given four times every two weeks. The staging as well as the restaging protocol after neoadjuvant chemotherapy include computed tomography of chest and abdomen and diagnostic laparoscopy. The primary study endpoint is progression-free survival. According to the sample size calculation, 155 patients need to be randomized to each treatment arm. Disease recurrence will be documented by scheduled computed tomography scans 9, 12, 15, 21 and thereafter every 6 months until disease progression. For quality control, circumferential resection margins are marked

    The history, present status and future prospects of adjuvants application in herbicides were briefly reviewed. Adjuvants can be separated into two groups, activator adjuvants and utility adjuvants. The former directly enhances the efficacy of a herbicide through increasement of herbicide absorption, spreading, cuticular penetration, rainfastness and retention enhancement, and photodegradation of the herbicide can also be decreased. And the latter is utilized for improving application characteristics, behaviors and physical properties of herbicides and reducing or minimizing unwanted side effects on application.

    2016-04-01

    Adjuvant chemotherapy (CTX) should be individualized to provide potential survival benefit and avoid potential harm to cancer patients. Our goal was to establish a computational approach for making personalized estimates of the survival benefit from adjuvant CTX. We developed Sub-Network based Random Forest classifier for predicting Chemotherapy Benefit (SNRFCB) based gene expression datasets of lung cancer. The SNRFCB approach was then validated in independent test cohorts for identifying chemotherapy responder cohorts and chemotherapy non-responder cohorts. SNRFCB involved the pre-selection of gene sub-network signatures based on the mutations and on protein-protein interaction data as well as the application of the random forest algorithm to gene expression datasets. Adjuvant CTX was significantly associated with the prolonged overall survival of lung cancer patients in the chemotherapy responder group (P = 0.008), but it was not beneficial to patients in the chemotherapy non-responder group (P = 0.657). Adjuvant CTX was significantly associated with the prolonged overall survival of lung cancer squamous cell carcinoma (SQCC) subtype patients in the chemotherapy responder cohorts (P = 0.024), but it was not beneficial to patients in the chemotherapy non-responder cohorts (P = 0.383). SNRFCB improved prediction performance as compared to the machine learning method, support vector machine (SVM). To test the general applicability of the predictive model, we further applied the SNRFCB approach to human breast cancer datasets and also observed superior performance. SNRFCB could provide recurrent probability for individual patients and identify which patients may benefit from adjuvant CTX in clinical trials.

    Purpose: To evaluate the tolerability and toxicity of administering vaginal brachytherapy (VB) concurrently during chemotherapy compared with the sequential approach for patients with endometrial cancer. Methods and Materials: A retrospective analysis of 372 surgically staged patients with endometrial cancer American Joint Committee on Cancer 2009 stages I to IV treated with adjuvant postoperative radiation therapy (RT) at our institution from 2001 to 2012 was conducted. All patients received VB + external beam RT (EBRT) + 6 cycles of adjuvant carboplatin- and paclitaxel-based chemotherapy. The VB mean dose was 15.08 Gy (range, 15-20 Gy), with 3 to 4 weekly applications, and the EBRT mean dose was 45 Gy delivered with 3-dimensional or intensity modulated RT techniques. Hematologic, gastrointestinal (GI), and genitourinary (GU) toxicities were assessed by Common Toxicity Criteria (CTC) and compared between sequential and concurrent chemotherapy and VB schedules. Results: Among patients who received RT and adjuvant chemotherapy, 180 of 372 patients (48%) received RT sandwiched between cycles 3 and 4 of chemotherapy. A separate group of 192 patients (52%) were treated with VB during the first 3 cycles of chemotherapy, with a weekly application on nonchemotherapy days, and received the EBRT portion in a sandwiched fashion. Patients treated with VB during chemotherapy had a decreased overall treatment time by 4 weeks (P<.001; 95% confidence interval: 3.99-4.02) and sustained no difference in CTC-graded acute hematologic, GI, or GU toxicities in comparison with the patients treated with VB and chemotherapy in a sequential manner (P>.05). CTC grade 3 or 4 hematologic, GI, and GU toxicities were zero. Conclusions: VB during chemotherapy is well tolerated, decreases overall treatment time, and does not render more toxicity than the sequential regimen.

    Chemotherapy for advanced colitis-associated colorectal cancer (CAC) has been insufficiently evaluated. The goal of this study was to clarify the efficacy and safety of chemotherapy for CAC in Japan. CAC patients who were treated with chemotherapy between 2005 and 2015 were retrospectively examined. Twenty-nine patients (median age, 48 years; 23 men) were assessed. Eighteen patients had ulcerative colitis, and 11 had Crohn's disease. Three ulcerative colitis and four Crohn's disease patients were in the active disease phase. Primary tumors were located in the rectum/anus (n=16), the left colon (n=9), or the right colon (n=4). Palliative or adjuvant chemotherapy was performed in 13 and 16 patients, respectively. First-line palliative chemotherapy regimens were as follows: fluorouracil, leucovorin, and oxaliplatin (FOLFOX; n=6), FOLFOX+bevacizumab (n=3), and others (n=4). Adjuvant chemotherapy regimens were S-1 (n=7), oxaliplatin-based (n=4) and others (n=5). In palliative chemotherapy, the objective response rate was 15%, and the median progression-free survival and overall survival were 182 and 315 days, respectively. In adjuvant chemotherapy, the 5-year relapse-free survival rate was 78%. Grade 3/4 adverse events (AEs) were observed in 16 patients (55%). Active and remission inflammatory bowel disease patients suffered grade 3/4 nonhematological AEs at an incidence of 71 and 23%, respectively (Pchemotherapy for CAC exhibited sufficient efficacy, whereas modest efficacy was shown for palliative chemotherapy for CAC. AEs, particularly nonhematological AEs, were closely associated with disease activity of colitis.

    Biliary tract cancer is a rare malignant tumor.There is limited knowledge about biology and natural history of this disease and considerable uncertainty remains regarding its optimal diagnostic and therapeutic management.The role of adjuvant therapy is object of debate and controversy.Although resection is identified as the most effective and the only potentially curative treatment,there is no consensus on the impact of adjuvant chemotherapy and/or radiotherapy on the high incidence of disease recurrence and on survival.This is mainly due to the rarity of this disease and the consequent difficulty in performing randomized trials.The only two prospectively controlled trials concluded that adjuvant chemotherapy did not improve survival.Most of the retrospective trials,which had limited sample size and included heterogeneous patients population and non-standardized therapies,suggested a marginal benefit of chemoradiotherapy in reducing locoregional recurrence and an uncertain impact on survival.Welldesigned multi-institutional randomized trials are necessary to clarify the role of adjuvant therapy.Two ongoing phase Ⅲ trials may provide relevant information.

    Full Text Available Myoepithelial carcinoma (malignant myoepithelioma of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy regimens. She presented with an elastic hard mass of the left breast. Breast conserving surgery was performed as part of both diagnosis and treatment. From the results of histological and immunohistochemical examinations, this case was considered to be a myoepithelial carcinoma. Fifteen months after the completion of adjuvant radiotherapy, distant metastasis of the left parasternal lymph node metastasis developed. She was treated by further excision and received a total of four regimens of chemotherapy including a combination of doxorubicin and cyclophosphamide. She received chemotherapy for 20 months after the diagnosis of metastasis.

    2015-11-01

    Over 15 years ago, low-dose metronomic chemotherapy was shown to induce disease control in patients with advanced-stage breast cancer with a lower incidence of adverse events compared with conventional maximum tolerated dose chemotherapy. Good response rates have been seen in heavily pre-treated patients for whom limited treatment options are available. Most patients prefer oral therapy and metronomic chemotherapy is a convenient alternative in patients with advanced-stage disease in which minimal toxicity and good tumour control are the overall aims of treatment. The addition of metronomic protocols to standard neoadjuvant chemotherapy regimens has produced promising pathological complete response rates. Ongoing trials including the SYSUCC-001 trial in patients with triple-negative breast cancer and the IBCSG 22-00 trial that is assessing a cyclophosphamide-methotrexate maintenance regimen after standard adjuvant therapy in hormone receptor-negative disease, will clarify the value of adding this approach to conventional therapies. The low cost associated with metronomic chemotherapy represents an opportunity for the utilization of this treatment option, especially in developing countries, and poses a challenge for the launch of large trials sponsored by industry. Using breast cancer as the principal example, we discuss the key clinical advances in this area, including new trial design, appropriate patient and end point selection, as well as the evolving rationale for metronomic chemotherapy combinations.

    Full Text Available Human FAM76B (hFAM76B is a 39 kDa protein that contains homopolymeric histidine tracts, a targeting signal for nuclear speckles. FAM76B is highly conserved among different species, suggesting that it may play an important physiological role in normal cellular functions. However, a lack of appropriate tools has hampered study of this potentially important protein. To facilitate research into the biological function(s of FAM76B, murine monoclonal antibodies (MAbs against hFAM76B were generated by using purified, prokaryotically expressed hFAM76B protein. Six strains of MAbs specific for hFAM76B were obtained and characterized. The specificity of MAbs was validated by using FAM76B-/- HEK 293 cell line. Double immunofluorescence followed by laser confocal microscopy confirmed the nuclear speckle localization of hFAM76B, and the specific domains recognized by different MAbs were further elucidated by Western blot. Due to the high conservation of protein sequences between mouse and human FAM76B, MAbs against hFAM76B were shown to react with mouse FAM76B (mFAM76B specifically. Lastly, FAM76B was found to be expressed in the normal tissues of most human organs, though to different extents. The MAbs produced in this study should provide a useful tool for investigating the biological function(s of FAM76B.

Methods All records of patients older than 16 years diagnosed with osteosarcoma of the head and neck in the Netherlands between 1993 and 2013 were reviewed. Results We identified a total of 77 patients with an osteosarcoma of the head and neck; the 5‐year overall survival (OS) was 55%. In 50 patients with surgically resected high‐ or intermediate‐grade osteosarcoma of the head and neck younger than 75 years, univariate and multivariable analysis, adjusting for age and resection margins, showed that patients who had not received chemotherapy had a significantly higher risk of local recurrence (hazard ratio [HR] = 3.78 and 3.66, respectively). Conclusion In patients younger than 75 years of age with surgically resected high‐ and intermediate‐grade osteosarcoma of the head and neck, treatment with (neo‐)adjuvant chemotherapy resulted in a significantly smaller risk of local recurrence. Therefore, we suggest (neo‐)adjuvant chemotherapy in patients amenable to chemotherapy. © 2016 The Authors Head & Neck Published by Wiley Periodicals, Inc. Head Neck 39: 140–146, 2017 PMID:27507299

    Adjuvant treatments, specifically chemotherapy and hormonal therapy, have dramatically increased breast cancer survival, resulting in increased attention to the residual effects of treatment. Breast cancer survivors (BCS) frequently report that cognitive deficits are a particular source of distress, interfering with many aspects of quality of life. The literature on neuropsychological performance measures in BCS supports the reality of subtle cognitive deficits after both chemotherapy and hormonal therapy. This premise is supported by recent imaging studies, which reveal anatomical changes after chemotherapy as well as changes in patterns of neural activation while performing cognitive tasks. This review suggests that, even when performance on neuropsychological performance measures is within normal limits, BCS may be using increased cognitive resources in the face of reduced cognitive reserve. Potential interventions for cognitive deficits after adjuvant therapy include prescriptions for healthy living, pharmacotherapy, complementary therapy, and cognitive remediation therapy directed toward specific cognitive deficits or a combination of several strategies.

    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.

    The role of chemotherapy in prostate cancer continues to evolve. In men with symptomatic androgen-independent prostate cancer, significant reduction in pain and analgesic requirements are achievable with mitoxantrone and glucocorticoid combinations compared with glucocorticoids alone. However, survival rates are not improved. Taxane-based combinations with estramustine phosphate or other new agents show promise. Prostate-specific antigen response rates with these combinations appear to be 1.5 to 2 times more frequent than with mitoxantrone-based combinations. Randomized trials of taxane versus mitoxantrone-based therapies are underway. New agents and applications of current agents in adjuvant settings should be explored if survival in men with prostate cancer is to be improved.

    Breast cancer in the elderly is an increasing clinical problem. In addition, ~60% of deaths from breast cancer occur in women aged 65 years and older. Despite this, older women with breast cancer have been underrepresented in clinical trials, and this has led to less than optimal evidence to guide their therapy. The management of elderly women with early breast cancer is a complex process that requires careful evaluation of life expectancy, comorbidities, patient values, and risks and benefits of available treatment options. This review will focus on current adjuvant systemic therapy options for older women with breast cancer, discuss the principles in the decision-making process, and define the role of endocrine therapy, chemotherapy, and targeted agents.

    We describe a case of a 62-year-old male with an epithelioid MPNST of the left foot. Multiple lung metastases developed after radical surgery on the primary lesion. The response to adjuvant chemotherapy including doxorubicin and ifosfamide was favorable, and thoracoscopic resection was subsequently performed on the remaining three metastases. No evidence of recurrence or metastasis was observed at the 12-month followup after the first operation. Further followup and chemotherapy may be required.

    Background The combination of cisplatin and vinorelbine is an evidence-supported regimen for adjuvant chemotherapy for treating non-small cell lung cancer (NSCLC).But this doublet has considerable toxicity and unfavorable tolerability,and results in poor compliance.The cisplatin and gemcitabine regimen is one of the most active and well-tolerated regimens against advanced NSCLC,but its toxicity and tolerability has not been adequately evaluated in the adjuvant setting.Methods From a lung cancer database we retrospectively reviewed NSCLC patients receiving adjuvant chemotherapy of cisplatin (75 mg/m2) and gemcitabine (1250 mg/m2) between January 2005 and December 2011.Postoperative demographics,compliance to adjuvant therapy and toxicity were retrieved from medical records.Results A total of 132 patients met the criteria and were included in the study,96 were male (72.7%) and 36 were female (27.3%).Median age was 60.5 years old,range 29-75 years,and 41.7% of patients were ≥65 years old.Overall,68.2%patients received all four planned cycles,and the cumulative dose delivered for gemcitabine was 8333 mg (83.3% of the planned dose) and cisplatin 248 mg (82.7% of the planned dose).There were no treatment-related deaths.Grade 3/4neutropenia developed in 47 patients (35.6%) and was the predominant hematologic toxicity.Common grade 3/4 nonhematologic toxicities were nausea/vomiting (22.0%),infection (12.3%),and febrile neutropenia (11.4%).Conclusion Cisplatin and gemcitabine are feasible for use in the adjuvant setting with a favorable toxicity profile and superior tolerability compared with published data on cisplatin and vinorelbine.

    There is accumulating clinical evidence that chemotherapeutic agents induce neurological side effects, including memory deficits and mood disorders, in cancer patients who have undergone chemotherapeutic treatments. This review focuses on chemotherapy-induced neurodegeneration and hippocampal dysfunctions and related mechanisms as measured by in vivo and in vitro approaches. These investigations are helpful in determining how best to further explore the causal mechanisms of chemotherapy-induced neurological side effects and in providing direction for the future development of novel optimized chemotherapeutic agents.

    Prior to the recent therapeutic advances, chemotherapy was the mainstay of treatment options for advanced-stage melanoma. A number of studies have investigated various chemotherapy combinations in order to expand on the clinical responses achieved with single-agent dacarbazine, but these have not demonstrated an improvement in overall survival. Similar objective responses were observed with the combination of carboplatin and paclitaxel as were seen with single-agent dacarbazine. The combination of chemotherapy and immunotherapy, known as biochemo-therapy, has shown high clinical responses; however, biochemo-therapy has not been shown to improve overall survival and resulted in increased toxicities. In contrast, palliation and long-term responses have been observed with localized treatment with isolated limb perfusion or infusion in limb-isolated disease. Although new, improved therapeutic options exist for first-line management of advanced-stage melanoma, chemotherapy may still be important in the palliative treatment of refractory, progressive, and relapsed melanoma. We review the various chemotherapy options available for use in the treatment and palliation of advanced-stage melanoma, discuss the important clinical trials supporting the treatment recommendations, and focus on the clinical circumstances in which treatment with chemotherapy is useful.

    Frequency of local and distant failures after gastrectomy has led to extended lymph nodes dissection to obtain a better locoregional control. However, five year survival rates were not significantly different between patients undergoing D2 and D1 lymphadenectomy, and higher morbidity and post operative deaths were reported in large randomized trials (respectively 25% vs 48% and 4 vs 13%). Additionally, several met-analysis failed to demonstrate a significant survival advantage with adjuvant chemotherapy. The results of the first trial demonstrating one advantage to adjuvant post-operative chemoradiotherapy should modify the standard care. Disease free and overall survival after surgery alone and after surgery and concurrent chemoradiotherapy were respectively 31% vs 48% and 41% vs 50%. The inter-group trial demonstrate that better local control improve survival if radiation fields include stamps, tumour bed, proximal nodal chains and nodes corresponding to D2 extended lymph nodes dissection. Treatment was feasible with few severe toxic effects (1%). Of the 281 patients, 17% stopped treatment because toxic effects. Technical modalities of radiotherapy and post-operative nutrition support which are critical points of interest for this treatment, are also discussed. (authors)

    At the 11th annual meeting of the Society of Urologic Oncology, an expert panel was convened to discuss the practical use of perioperative chemotherapy for muscle-invasive bladder cancer. The discussion was structured as a case-based debate among the panelists. The topics included: neoadjuvant chemotherapy with a focus on T2 disease, pros and cons, survival data, tolerability of cisplatin-based therapy, can we avoid radical cystectomy in complete responders, limitations and alternatives to cisplatin-based therapy, management of 'suboptimal' chemotherapy, residual disease after neoadjuvant chemotherapy, adjuvant chemotherapy, and key aspects of radical cystectomy and lymph-node dissection in multimodal therapy. The presentations were derived from published literature. The panelists agreed that patients with muscle-invasive bladder cancer should be managed with a multidisciplinary team, including urologist and medical oncologist. Cisplatin-based neoadjuvant chemotherapy has demonstrated improved survival and should be incorporated into the management of all eligible patients with muscle-invasive bladder cancer. However, in some centers, neoadjuvant chemotherapy is reserved for patients with >T2 disease or high-risk features. There are no data for the administration of non-cisplatin-based neoadjuvant chemotherapy, such as carboplatin-combinations. Cisplatin-ineligible patients should proceed directly to surgical extirpation with adjuvant cisplatin-based chemotherapy considered based on pathologic findings. However, the data for adjuvant chemotherapy is less compelling. As our refinement of the selection process continues, we may be able to better identify subsets of patients who may be spared chemotherapy, but much work remains to be done in this arena. The current standard for muscle-invasive bladder cancer patients is cisplatin-based neoadjuvant chemotherapy followed by radical cystectomy and pelvic lymph-node dissection.

    In North America, gastric cancer is the third most common gastrointestinal malignancy and the third most lethal neoplasm overall. In Asia, gastric cancer represents an even more serious problem: in Japan, it is the most common cancer in men. The standard primary therapy for gastric cancer is surgical resection; in esophagogastric-junction (EGJ) adenocarcinoma, which is often included in studies of gastric cancer, surgery is also typically the initial management strategy. However, the rates of locoregional and distant recurrence following surgery with curative intent have remained high. Investigators have explored a variety of ways of reducing these rates and improving survival in patients with gastric and EGJ cancers. These strategies have included explorations of the optimal extent of regional lymphadenectomy at the time of gastric resection; investigation of different neoadjuvant, perioperative, and adjuvant chemotherapy regimens; use of preoperative and postoperative radiation therapy; and the use of pre- and postoperative chemoradiotherapy (CRT).To date, benefit has been seen in gastric cancer patients with the use of what is called a"D2 resection"(which includes lymph nodes of stations 7 through 12) and with adjuvant CRT (in the West) or adjuvant chemotherapy with S-1 (in Japan); and neoadjuvant CRT has been shown to have a survival benefit in patients with EGJ cancers.

    N-glycosylation of proteins is important for protein folding and function. We have recently reported that FAM5C/BRINP3 contributes to the tumor necrosis factor-α-induced expression of leukocyte adhesion molecules in vascular endothelial cells (ECs). However, regulatory mechanism of the FAM5C biosynthesis is poorly understood. Co-immunoprecipitation assay revealed the interaction of FAM5C with UDP-glucose:glycoprotein glucosyltransferase 1 (UGGT1), a glycoprotein folding-sensor enzyme. FAM5C ectopically expressed in HEK293 cells was localized to the endoplasmic reticulum and co-localized with endogenously expressed UGGT1. Molecular size of FAM5C was reduced by treatment with N-glycosidase F and in FAM5C-expressing cells cultured in the presence of the N-glycosylation inhibitor tunicamycin. FAM5C was secreted by the cells and the secretion of FAM5C was blocked by tunicamycin. Among six potential N-glycosylation sites, the potential site at Asn(168) was not N-glycosylated, and Asn(337), Asn(456), Asn(562), Asn(609), and Asn(641) mutants were poorly secreted by the cells. These results demonstrated that FAM5C is an N-glycosylated protein and N-glycosylation is necessary for the secretion of FAM5C.

    1990-06-01

    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.

    2016-01-01

    Vaccination is one of the most efficient strategies for the prevention of infectious diseases. Although safer, subunit vaccines are poorly immunogenic and for this reason the use of adjuvants is strongly recommended. Since their discovery in the beginning of the 20th century, adjuvants have been used to improve immune responses that ultimately lead to protection against disease. The choice of the adjuvant is of utmost importance as it can stimulate protective immunity. Their mechanisms of action have now been revealed. Our increasing understanding of the immune system, and of correlates of protection, is helping in the development of new vaccine formulations for global infections. Nevertheless, few adjuvants are licensed for human vaccines and several formulations are now being evaluated in clinical trials. In this review, we briefly describe the most well known adjuvants used in experimental and clinical settings based on their main mechanisms of action and also highlight the requirements for licensing new vaccine formulations.

    Wenjin Yin

    Full Text Available BACKGROUND: Adjuvant trastuzumab therapy has yielded conflicting results for overall survival, concerns about central nervous system (CNS metastasis, and questions about optimal schedule. Therefore, we carried out a meta-analysis to assess the benefits of concurrent or sequential trastuzumab with adjuvant chemotherapy for early breast cancer patients with HER2-positive tumors. METHODS: Computerized and manual searches were performed to identify randomized clinical trials comparing adjuvant chemotherapy with or without trastuzumab in HER2-positive early breast cancer patients. Odds ratios were used to estimate the association between the addition of trastuzumab to adjuvant chemotherapy and various survival outcomes. The fixed-effects or random-effects model was used to combine data. FINDINGS: With six eligible studies identified, this analysis demonstrated that patients with HER2-positive breast cancer derived benefit in disease-free survival, overall survival, locoregional recurrence and distant recurrence (all P<0.001 from the addition of trastuzumab to adjuvant chemotherapy, whereas trastuzumab did worse in CNS recurrence as compared to the control group (P = 0.018. Furthermore, concomitant use of trastuzumab significantly lowered the hazard of death (P<0.001 but bore a higher incidence of CNS recurrence (P = 0.010, while statistical significance failed to be discerned for either overall survival (P = 0.069 or CNS metastasis (P = 0.374 between the sequential and observation arms. CONCLUSION: This analysis verifies the efficacy of trastuzumab in the adjuvant setting. Additionally, our findings indirectly corroborate the superiority of concurrent trastuzumab to sequential use and also illuminate that prolonged survival is the possible reason for the higher incidence of CNS with trastuzumab versus observation.

    2009-01-01

    Full Text Available Although cancer therapies have experienced great success nowadays, yet the associated toxic response and free radicals formation have resulted in significant number of treatment-induced deaths rather than disease-induced fatalities. 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. Twenty children (group I have taken vitamin E and NAC supplementations with chemotherapy and the other twenty children (group II have not taken any adjuvant antioxidant therapy. They were evaluated clinically for the occurrence of complications and by the laboratory parameters (blood levels of glutathione peroxidase (Glu.PX antioxidant enzyme, malondialdehyde (MDA, tumor necrosis factor- (TNF-, liver enzymes, and bone marrow picture. Results revealed reduced chemotherapy and radiotherapy toxicity as evidenced by decreasing level of MDA, increasing level of Glu.Px and decreased occurrence of toxic hepatitis, haematological complications, and need for blood and platelet transfusions in group I compared to group II. We can conclude that vitamin E and NAC have been shown to be effective as antioxidant adjuvant therapy in children with ALL to reduce chemo-/radiotherapy-related toxicities during the initial period of treatment.

    Full Text Available Biliary-tract cancers are rare tumors and carry poor prognosis despite some aggressive surgical approach. The benefit of adjuvant treatment is under debate, and except one there is no phase III trial available. However, it appears that, in a large proportion, adjuvant therapy is proposed to patient. It could be chemotherapy or radiotherapy alone or both. Many publications are available on this topic. These are sometimes phase II studies, but mostly retrospective data about the experience of one center. All these studies have got many bias and the results must be interpreted with caution, even if patients could get some benefit of adjuvant therapy in case of adverse prognostic factors as positive resection margin and/or nodal involvement. In this review, we sum up the different therapies used as adjuvant treatment for biliary-tract cancer, and then we have studied what is done in clinical practice in order to propose a phase III clinical trial in this setting.

    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.

    Vaccination can provide a safe alternative to chemotherapy by using the body's natural defense mechanisms to create a potent immune response against tumor cells. Peptide-based therapeutic vaccines against human papillomavirus (HPV)-related cancers are usually designed to elicit cytotoxic T cell responses by targeting the HPV-16 E7 oncoprotein. However, peptides alone lack immunogenicity, and an additional adjuvant or external delivery system is required. In this study, we developed new polymer-peptide conjugates to create an efficient self-adjuvanting system for peptide-based therapeutic vaccines. These conjugates reduced tumor growth and eradicated E7-positive TC-1 tumors in mice after a "single shot" immunization, without the help from an external adjuvant. The new conjugates had a significantly higher anticancer efficacy than the antigen formulated with a commercial adjuvant. Furthermore, the polymer-peptide conjugates were promptly taken up by antigen presenting cells, including dendritic cells and macrophages, and efficiently activated CD4(+) T-helper cells and CD8(+) cytotoxic T lymphocyte cells.

    To evaluate the effectiveness of Uncaria tomentosa in minimizing the side effects of chemotherapy and improving the antioxidant status of colorectal cancer (CRC) patients, a randomized clinical trial was conducted. Patients (43) undergoing adjuvant/palliative chemotherapy with 5-Fluorouracil/leucovorin + oxaliplatin (FOLFOX4) were split into two groups: the UT group received chemotherapy plus 300 mg of Uncaria tomentosa daily and the C group received only FOLFOX4 and served as a control. Blood samples were collected before each of the 6 cycles of chemotherapy, and hemograms, oxidative stress, enzymes antioxidants, immunologic parameters, and adverse events were analyzed. The use of 300 mg of Uncaria tomentosa daily during 6 cycles of FOLFOX4 did not change the analyzed parameters, and no toxic effects were observed.

    The development of effective vaccines against neglected diseases, especially those associated with poverty and social deprivation, is urgently needed. Modern vaccine technologies and a better understanding of the immune response have provided scientists with the tools for rational and safer design of subunit vaccines. Often, however, subunit vaccines do not elicit strong immune responses, highlighting the need to incorporate better adjuvants; this step therefore becomes a key factor for vaccine development. In this review we outline some key features of modern vaccinology that are linked with the development of better adjuvants. In line with the increased desire to obtain novel adjuvants for future vaccines, the Finlay Adjuvant Platform offers a novel approach for the development of new and effective adjuvants. The Finlay Adjuvants (AFs), AFPL (proteoliposome), and AFCo (cochleate), were initially designed for parenteral and mucosal applications, and constitute potent adjuvants for the induction of Th1 responses against several antigens. This review summarizes the status of the Finlay technology in producing promising adjuvants for unsolved-vaccine diseases including mucosal approaches and therapeutic vaccines. Ideas related to adjuvant classification, adjuvant selection, and their possible influence on innate recognition via multiple toll-like receptors are also discussed. PMID:24348475

    Questions have been recently raised regarding the safety of vaccine adjuvants, particularly in relation to autoimmunity or autoimmune disease(s)/disorder(s) (AID). The International Life Sciences Institute (ILSI) Health and Environmental Sciences Institute (HESI) formed a scientific committee and convened a 2-day workshop, consisting of technical experts from around the world representing academia, government regulatory agencies, and industry, to investigate and openly discuss the issues around adjuvant safety in vaccines. The types of adjuvants considered included oil-in-water emulsions and toll-like receptor (TLR) agonists. The state of science around the use of animal models and biomarkers for the evaluation and prediction of AID were also discussed. Following extensive literature reviews by the HESI committee, and presentations by experts at the workshop, several key points were identified, including the value of animal models used to study autoimmunity and AID toward studying novel vaccine adjuvants; whether there is scientific evidence indicating an intrinsic risk of autoimmunity and AID with adjuvants, or a higher risk resulting from the mechanism of action; and if there is compelling clinical data linking adjuvants and AID. The tripartite group of experts concluded that there is no compelling evidence supporting the association of vaccine adjuvants with autoimmunity signals. Additionally, it is recommended that future research on the potential effects of vaccine adjuvants on AID should consider carefully the experimental design in animal models particularly if they are to be used in any risk assessment, as an improper design and model could result in misleading information. Finally, studies on the mechanistic aspects and potential biomarkers related to adjuvants and autoimmunity phenomena could be developed.

    Background The purpose of the study was to evaluate the role of neoadjuvant chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries in treating patients with advanced ovarian epithelial carcinoma.Methods Forty-two patients with advanced ovarian epithelial carcinoma (study group) were treated via the anterior branches of the bilateral internal iliac arteries after cytoreductive surgery and 7 courses of adjuvant platinum-based combination chemotherapy. Primary cytoreductive surgery was performed in 43 patients with advanced ovarian epithelial carcinoma (control group), and then followed by 8 courses of adjuvant platinum-based combination chemotherapy. The rate of optimal cytoreductive surgery, survival rate, blood loss during operation and operative time were investigated in the two groups. Statistical significance was asessed using Student's t test, the Chi-squre test and the log-rank test. Results In the study group, the rate of optimum debulking after platinum-based chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries was 71.43%(30/42) (χ2=10.06, P0.05).Conclusions Neoadjuvant platinum-based combination chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries is an alternative treatment for patients with advanced ovarian epithelial carcinoma, in whom the chance of optimal cytoreductive surgery is low. The treatment can reduce blood loss, decrease operative time, and increase the rate of optimal cytoreductive surgery; but the median survival can't be improved significantly.

    Askin tumor is a tumor of the thoracopulmonary region that most commonly affects children and adolescents. These rare tumors are a form of primitive neuroectodermal tumor and typically carry a poor prognosis. Treatment is multimodal and consists of a combination of neoadjuvant chemotherapy, radical resection, and adjuvant chemo- and radiotherapy or all of the above. Surgery is advocated in most cases. We report a case of Askin tumor in a 54-year-old male who showed rapid and complete response to neoadjuvant chemotherapy. This allowed potentially radical surgery to be avoided. At one-year follow-up he remains disease-free.

    Cancer patients who start receiving chemotherapy have difficulty in understanding the state of their disease, the prognosis, and the purpose of treatment. We used a survey to evaluate the extent of perception of chemotherapy goal among cancer patients. Two hundred sixteen cancer patients who received chemotherapy for the first time participated in the study. The presence of depression and anxiety was assessed using the "Hospital Anxiety and Depression Scale" (HAD). The consistency between the patients' perception of the chemotherapy goal and the physician's perception was described as "right," and the inconsistency was described as "wrong." Among the patients who participated in the survey, 53.2 % (n = 115) were receiving adjuvant treatment and 46.8 % (n = 101) were receiving palliative treatment for metastatic disease. The rate of right and wrong perception of the chemotherapy goal was 51.9 % (n = 108) and 32.2 % (n = 67), respectively, and the rate of confused patients was 18.9 % (n = 41). The level of education was shown to be the only parameter involved in accurate perception of the treatment purpose (hazard ratio (HR) = 0.444, p = 0.025, 95 % confidence interval (CI) 0.219-0.903). In this study, there was a 51.9 % consistency between the physician's perception and that of the patient regarding the purpose of treatment. We demonstrated that the level of education was the unique factor in accurate perception of chemotherapy goal among cancer patients.

    To determine the receipt and impact of adjuvant therapy on overall survival (OS) for anaplastic astrocytoma (AA). Data were extracted from the National Cancer Data Base (NCDB). Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 4807 patients with AA diagnosed from 2004 to 2013 who underwent surgery were identified. 3243 (67.5 %) received adjuvant chemoRT, 525 (10.9 %) adjuvant radiotherapy (RT) alone, 176 (3.7 %) adjuvant chemotherapy alone and 863 (18.0 %) received no adjuvant therapy. Patients were more likely to receive adjuvant chemoRT if they were diagnosed in 2009-2013 (p = 0.022), were ≤ 50 years (p < 0.001), were male (p = 0.043), were Asian or White race (p < 0.001), had private insurance (p < 0.001), had income ≥$38,000 (p < 0.001), or underwent total resection (p < 0.003). Those who received adjuvant chemoRT had significantly better 5-year OS than the other adjuvant treatment types (41.8 % vs. 31.2 % vs. 29.8 % vs. 27.4 %, p < 0.001). This significant 5-year OS benefit was also observed regardless of age at diagnosis. Of those undergoing adjuvant chemoRT, those receiving ≥59.4 Gy had significantly better 5-year OS than those receiving <59.4 Gy (44.4 % vs. 25.9 %, p < 0.001). There was no significant difference in OS when comparing 59.4 Gy to higher RT doses. On multivariate analysis, receipt of adjuvant chemoRT, age at diagnosis, extent of disease, and insurance status were independent prognostic factors for OS. Adjuvant chemoRT is an independent prognostic factor for improved OS in AA and concomitant chemoRT should be considered for all clinically suitable patients who have undergone surgery for the disease.

    Purpose: To evaluate survival in patients with resected pancreatic cancer treated with concurrent chemoradiation with or without adjuvant gemcitabine (Gem). Methods and Materials: From 1998 to 2010, 86 patients with pancreatic adenocarcinoma who underwent resection were treated with adjuvant concurrent chemoradiation. Thirty-four patients received concurrent 5-fluorouracil-based chemoradiation (5-FU/RT) with traditional field radiation (range, 45-61.2 Gy; median, 50.4 Gy) without further adjuvant therapy. Thirty patients received traditional field 5-FU/RT (range, 45-60.4 Gy; median, 50.4 Gy) with Gem (1,000 mg/m{sup 2} weekly) either before and after radiotherapy or only after radiotherapy. Twenty-two patients received concurrent full-dose Gem (1,000 mg/m{sup 2} weekly)-based chemoradiation (Gem/RT), consisting of involved-field radiation (range, 27-38 Gy; median, 36 Gy) followed by further adjuvant Gem. Results: The median age of the cohort was 65 years (range, 40-80 years). Of the patients, 58 had T3 tumors (67%), 22 had T2 tumors (26%), and 6 had T1 tumors (7%). N1 disease was present in 61 patients (71%), whereas 18 patients (21%) had R1 resections. Performance status, lymph node status, and margin status were all similar among the treatment groups. Median follow-up was 19.0 months. Median overall survival (OS) (19.2 months, 19.0 months, and 21.0 months) and 3-year OS rates (26.5%, 27.2%, and 32.1%) were similar among patients with 5-FU/RT with no adjuvant Gem, those with 5-FU/RT with adjuvant Gem, and those with Gem/RT with adjuvant Gem, respectively (p = 0.88). Patients who received adjuvant Gem had a similar median OS (22.1 months) and 3-year OS rate (29%) compared to patients who did not (19.2 months and 26.5%, respectively) (p = 0.62). There was a trend for improved 3-year OS rates in patients with R0 vs. R1 resections (28.1% vs. 14.2%, p = 0.06) and in patients with T1 and T2 vs. T3 tumors (38% vs. 20%, p = 0.09). Node-negative patients had an improved 3

    Radiotherapy combined with chemotherapy is still used for standard treatment in patients with locally advanced unresectable cancer. A study was undertaken to compare a sequential (neo-adjuvant) with a simultaneous (concurrent) chemotherapy and radiotherapy program. Neo-adjuvant chemotherapy with cisplatin (80 mg/m{sup 2} i.v. day 1) and 5FU (600 mg/m{sup 2} continuous i.v. day 1-5) every 3 weeks prior to definitive conventional radiotherapy (60-65 Gy), or cisplatin (20 mg/m{sup 2} i.v. day 1-5) and 5FU (250 mg/m{sup 2} continuous i.v. infusion. day 1-14) were given simultaneously for same radiotherapy. Complete response rate was 45% in the sequential treatment and 43% in the simultaneous arm. Leukopenia and other adverse effects were slightly more frequent in the simultaneous arm, but there were no significant differences. These results suggested that individualization of treatment planning and establishment of optimum treatment were most important for combination of chemotherapy and radiotherapy. (author).

    Science.gov (United States)

    Zhu, Motao; Wang, Rongfu; Nie, Guangjun

    2014-01-01

    Vaccine adjuvants are applied to amplify the recipient's specific immune responses against pathogen infection or malignancy. A new generation of adjuvants is being developed to meet the demands for more potent antigen-specific responses, specific types of immune responses, and a high margin of safety. Nanotechnology provides a multifunctional stage for the integration of desired adjuvant activities performed by the building blocks of tailor-designed nanoparticles. Using nanomaterials for antigen delivery can provide high bioavailability, sustained and controlled release profiles, and targeting and imaging properties resulting from manipulation of the nanomaterials' physicochemical properties. Moreover, the inherent immune-regulating activity of particular nanomaterials can further promote and shape the cellular and humoral immune responses toward desired types. The combination of both the delivery function and immunomodulatory effect of nanomaterials as adjuvants is thought to largely benefit the immune outcomes of vaccination. In this review, we will address the current achievements of nanotechnology in the development of novel adjuvants. The potential mechanisms by which nanomaterials impact the immune responses to a vaccine and how physicochemical properties, including size, surface charge and surface modification, impact their resulting immunological outcomes will be discussed. This review aims to provide concentrated information to promote new insights for the development of novel vaccine adjuvants.

  13. The role of adjuvants in therapeutic protection against paracoccidioidomycosis after immunization with the P10 peptide

    2012-05-01

    Full Text Available Paracoccidioidomycosis (PCM, a common chronic mycosis in Latin America, is a granulomatous systemic disease caused by the thermo-dimorphic fungus Paracoccidioides brasiliensis. The glycoprotein gp43 is the main antigen target of P. brasiliensis and a 15-mer internal peptide (QTLIAIHTLAIRYAN, known as P10, defines a major CD4+-specific T cell epitope. Previous results have indicated that, besides having a preventive role in conventional immunizations prior to challenge with the fungus, protective anti-fungal effects can be induced in P. brasiliensis-infected mice treated with P10 administered with complete Freund’s adjuvant (CFA. The peptide elicits an IFN--dependent Th1 immune response and is the main candidate for effective immunotherapy of patients with PCM, as an adjunctive approach to conventional chemotherapy. In the present study we tested the therapeutic effects of P10 combined with different adjuvants (aluminum hydroxide, CFA, flagellin and the cationic lipid dioctadecyl-dimethylammonium bromide (DODAB in BALB/c mice previously infected with the P. brasiliensis Pb18 strain. Significant reductions in the number of colony forming units (CFUs of the fungus were detected in lungs of mice immunized with P10 associated with the different adjuvants 52 days after infection. Mice treated with DODAB and P10, followed by mice treated with P10 and flagellin, showed the most prominent effects as demonstrated by the lowest numbers of viable yeast cells as well as reductions in granuloma formation and fibrosis. Concomitantly, secretion of IFN- and TNF-, in contrast to IL-4 and IL-10, was enhanced in the lungs of mice immunized with P10 in combination with the tested adjuvants, with the best results observed in mice treated with P10 and DODAB. In conclusion, the present results demonstrate that the co-administration of the synthetic P10 peptide with several adjuvants, particularly DODAB, have significant therapeutic effects in experimental

    Pre- and peri-operative strategies are becoming standard for the management of localized gastro-esophageal cancer. For localized gastric/gastro-esophageal junction (GEJ) cancer there are conflicting data that a peri-operative approach with cisplatin-based chemotherapy improves survival, with the benefits seen in esophageal cancer likely less than a 5-10% incremental improvement. Further trends toward improvement in local control and survival, when combined chemotherapy and radiation therapy are given pre-operatively, are suggested by recent phase III trials. In fit patients, a significant survival benefit with pre-operative chemoradiation is seen in those patients who achieve a pathologic complete response. In esophageal/GEJ cancer, definitive chemoradiation is now considered in medically inoperable patients. In squamous cell carcinoma of the esophagus, surgery after primary chemoradiation is not clearly associated with an improved overall survival, however, local control may be better. In localized gastric/GEJ cancer, the integration of bevacizumab with pre-operative chemotherapy is being explored in large randomized studies, and with chemoradiotherapy in pilot trials. The addition of anti-epidermal growth factor receptor and anti-human epidermal growth factor receptor-2 antibody treatment to pre-operative chemoradiation continues to be explored. Early results show the integration of targeted therapy is feasible. Metabolic imaging can predict early response to pre-operative chemotherapy and biomarkers may further predict response to pre-operative chemo-targeted therapy. A multimodality approach to localized gastro-esophageal cancer has resulted in better outcomes. For T3 or node-positive disease, surgery alone is no longer considered appropriate and neo-adjuvant therapy is recommended. The future of neo-adjuvant strategies in this disease will involve the individualization of therapy with the integration of molecular signatures, targeted therapy, metabolic imaging

    Full Text Available A complex structure has the characters of many degrees of freedom and intricate shape, especially inelastic behavior under strong external loadings. It is hard to apply the structural control technology to it. In this paper, a new method that combines the Market-Based Control (MBC strategy and Force Analogy Method (FAM is presented to analyze the inelastic behavior of structure with magnetorheological dampers. The MBC is used to reduce the structural vibration response, and FAM is proposed to perform the inelastic analysis. A numerical example is used to compare the control effect of the new method and LQR algorithm, which show the accuracy and efficiency of the proposed computational method.

    AIM: To evaluate the efficacy and toxicity of postoperative chemoradiation using FP chemotherapy and oral capecitabine during radiation for advanced gastric cancer following curative resection.METHODS: Thirty-one patients who had underwent a potentially curative resection for Stage Ⅲ and Ⅳ (MO) gastric cancer were enrolled. Therapy consists of one cycle of FP (continuous infusion of 5-FU 1000 mg/m2 on d 1 to 5 and cisplatin 60 mg/m2 on d 1) followed by 4500 cGy (180 cGy/d) with capecitabine (1650 mg/m2 daily throughout radiotherapy). Four wk after completion of the radiotherapy, patients received three additional cycles of FP every three wk. The median follow-up duration was 22.2 mo.RESULTS: The 3-year disease free and overall survival in this study were 82.7% and 83.4%, respectively. Four patients (12.9%) showed relapse during follow-up. Eight patients did not complete all planned adjuvant therapy.Grade 3/4 toxicities included neutropenia in 50.2%, anemia in 12.9%, thrombocytopenia in 3.2% and nausea/vomiting in 3.2%. Neither grade 3/4 hand foot syndrome nor treatment related febrile neutropenia or death were observed.CONCLUSION: These preliminary results suggest that this postoperative adjuvant chemoradiation regimen of FP before and after capecitabine and concurrent radiotherapy appears well tolerated and offers a comparable toxicity profile to the chemoradiation regimen utilized in INT-0116. This treatment modality allowed successful loco-regional control rate and 3-year overall survival.

    The purpose of this study was to compare survival and risk of adverse events in women with early stage breast cancer (BC) treated with (1) doxorubicin (A), cyclophosphamide (C) + paclitaxel (P), (2) fluorouracil (F), epirubicin (E), cyclophosphamide (C) + docetaxel (D), or (3) dose-dense AC-P. Retrospective cohort study including 8462 women aged ≥18 years, with resected stage I-III BC, diagnosed between 2003 and 2009 in Ontario, identified through linkage of administrative databases. Primary outcome is overall survival (OS). Secondary outcomes are emergency room (ER) visits/hospitalizations, heart failure (HF), and leukemia. 4710 women were treated with FEC-D, 2065 with AC-P, and 1687 with dd AC-P. Adjusted 5-year OS was 92.1, 87.7, and 90.3 %, for each regimen, respectively (p = 0.0006). There was no difference in OS for FEC-D and dd AC-P in the propensity score-matched analyses (HR 1.24, 95 % CI 0.99-1.55). Five-year risk of HF was also similar (HR 1.09; 0.66-1.791.4 % for dd AC-P and 1.3 % for FEC-D and, p = 0.72). Treatment with FEC-D was significantly associated with ER visits and hospital admissions (p < 0.0001). The risks of leukemia were low and similar among the 3 groups (AC-P: 0.34 %, FEC-D: 0.08 %, dd AC-P: 0.12 %; p = 0.09). Although the efficacy of the three regimens was similar to that observed in randomized trials, we report higher toxicity with the use of these regimens in clinical practice. This was especially concerning for the docetaxel-containing regimen.

    cancer cells of 30 patients with advanced gastric cancer who underwent surgical treatment. Correlation between test results, clinical and anatomopathological aspects, disease staging, were dane using the same methodology of study performed in Japanese patients presented in master dissertation. METHODS: MTT test was carried out in cancer cells of 30 patients with gastric adenocarcinoma submitted to surgical treatment in the Department of Surgery at Santa Casa de São Paulo, Medical School. The following drugs were studied in vitro: mitomycin C, doxorubicin, cisplatin and 5-fluorouracil. RESULTS: Efficacy rates on tumors cells were reported as being: 16.6% for mitomycin C, 10.0 % for doxorubicin, 6.6% for cisplatin and 6.6% for 5-fluorouracil. There were no statistically significant correlations between chemosensitivity and age, sex, microscopic aspect and disease staging (p0.05. CONCLUSION: The effect of the studied chemotherapeutical drugs on gastric cancer cell cultivated in vitro is low. The results of chemotherapy effect in vitro proved no statistical correlation with age, sex, microscopic aspect and disease staging of these patients. Using the same methodology in our patients (non oriental or in Japanese patients the chemosensitivity was low in both studies. We can conclude that no matter which race is studied it will get the same low response results of chemosensitivity. With development of new chemotherapeutics agents the expectation is greater for better results in clinical practice. With the utilization and the spread of the MTT chemosensitivity test in our patients it will be possible to create protocols and multicentric studies for selection of new chemotherapeutic agents.

    Background: In the era of preoperative chemoradiotherapy (CRT) and total mesorectal excision (TME), the development of distant metastases is the predominant mode of failure in rectal cancer patients today. Integrating more effective systemic therapy into combined modality programs is the challenge. The question that needs to be addressed is how and when to apply systemic treatment with adequate dose and intensity. Material and Methods: This review article focuses on phase II-III trials designed to improve 5-fluorouracil (5-FU)-based combined modality treatment for rectal cancer patients through the inclusion of concurrent, adjuvant or, most recently, induction combination chemotherapy. Computerized bibliographic searches of PubMed were supplemented with hand searches of reference lists and abstracts of ASCO/ASTRO/ESTRO meetings. Results: After preoperative CRT and surgical resection, approximately one third of patients do not receive adjuvant chemotherapy, mainly due to surgical complications, patients' refusal, or investigator's discretion. In order to be able to apply chemotherapy with sufficient dose and intensity, an innovative approach is to deliver systemic therapy prior to preoperative CRT rather than adjuvant chemotherapy. Emerging evidence from several phase II trials and, recently, randomized phase II trials indicate that induction chemotherapy is feasible, does not compromise CRT or surgical resection, and enables the delivery of chemotherapy in adequate dose and intensity. Although this approach did not increase local efficacy in recent trials (e.g., pathological complete response rates, tumor regression, R0 resection rates, local control), it may help to improve control of distant disease. Conclusion: Whether this improvement in applicability and dose density of chemotherapy will ultimately translate into improved disease-free survival will have to be tested in a larger phase III trial.

    Purpose: this retrospective study compares patients treated between 1991 and 1998 with neoadjuvant radiotherapy {+-} chemotherapy (RCT) or adjuvant RCT for locally advanced noninflammatory breast cancers (LABC) in terms of pathologic complete response (pCR), 10-year relapse-free (RFS), and overall survival (OS). Patients and methods: preoperative RCT in 315 and adjuvant RCT in 329 cases consisted in 50 Gy (5 x 2 Gy/week) to the breast and the supra-/infraclavicular lymph nodes. 101 neoadjuvant patients received - in case of breast conservation - a 10-Gy interstitial boost with {sup 192}Ir afterloading before and 214 neoadjuvant patients a preoperative electron boost after external-beam radiotherapy. In the neoadjuvant RCT group, chemotherapy was applied prior to radiotherapy in 192 patients, and simultaneously in 113; ten had no chemotherapy. In the adjuvant RCT group, chemotherapy was applied to 44 patients before surgery and to 166 after surgery; 119 had no chemotherapy. Results: breast conservation became possible in 50.8% after neoadjuvant RCT for LABC with a pCR rate at surgery of 29.2%. A complete nodal remission (pNO) after RCT was observed in 56% (89/159) of the cN+ (clinically node-positive) neoadjuvant patients. There were trends in favor of preoperative RCT for RFS and OS (hazard ratio [HR] = 0.85; p = 0.09 for RFS; HR = 0.8130; p = 0.1037 for OS). For patients with cT2 tumors the RFS and OS were statistically significantly better (HR = 0.5090; p = 0.0130 for RFS; HR = 0.4390; p = 0.0026 for OS) after neoadjuvant compared to adjuvant RCT. Conclusion: neoadjuvant RCT achieved a pCR rate of 29.2% and a statistically significantly better RFS and OS in patients with cT2-category breast cancer. (orig.)

    Protracted preoperative radio-chemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neo-adjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a 'Total Meso-rectal Excision'. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: 'rectal cancer', 'preoperative radiotherapy', 'phase II-III', 'preoperative chemotherapy', 'adjuvant chemotherapy' and 'surgery'. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neo-adjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

    Full Text Available Background and objective To study the role of postoperative chemotherapy and its prognostic effect in Masaoka-Koga stage III and IV thymic tumors. Methods Between 1994 and 2012, 1,700 patients with thymic tumors who underwent surgery without neoajuvant therapy were enrolled for the study. Among them, 665 patients in Masaoka-Koga stage III and IV were further analyzed to evaluate the clinical value of postoperative chemotherapy. The Kaplan-Meier method was used to obtain the survival curve of the patients divided into different subgroups, and the Cox regression analysis was used to make multivariate analysis on the factors affecting prognosis. A Propensity-Matched Study was used to evaluate the clinical value of chemotherapy. Results Two-hundred-twenty-one patients were treated with postoperative chemotherapy, while the rest 444 cases were not. The two groups showed significant differences (P<0.05 regarding the incidence of myasthenia gravis, World Health Organization (WHO histological subtypes, pathological staging, resection status and the use of postoperative radiotherapy. WHO type C tumors, incomplete resection, and postoperative radiotherapy were significantly related to increased recurrence and worse survival (P<0.05. Five-year and 10-year disease free survivals (DFS and recurrence rates in patients who underwent surgery followed by postoperative chemotherapy were 51% and 30%, 46% and 68%, comparing with 73% and 58%, 26% and 40% in patients who had no adjuvant chemotherapy after surgery (P=0.001, P=0.001, respectively. In propensity-matched study, 158 pairs of patients with or without postoperative chemotherapy (316 patients in total were selected and compared accordingly. Similar 5-year survival rates were detected between the two groups (P=0.332. Conclusion Pathologically higher grade histology, incomplete resection, and postoperative radiotherapy were found to be associated with worse outcomes in advanced stage thymic tumors. At present

    Vaccines require optimal adjuvants including immunopotentiator and delivery systems to offer long term protection from infectious diseases in animals and man. Initially it was believed that adjuvants are responsible for promoting strong and sustainable antibody responses. Now it has been shown that adjuvants influence the isotype and avidity of antibody and also affect the properties of cell-mediated immunity. Mostly oil emulsions, lipopolysaccharides, polymers, saponins, liposomes, cytokines,ISCOMs (immunostimulating complexes), Freund's complete adjuvant, Freund's incomplete adjuvant, alums, bacterial toxins etc.,are common adjuvants under investigation. Saponin based adjuvants have the ability to stimulate the cell mediated immune system as well as to enhance antibody production and have the advantage that only a low dose is needed for adjuvant activity. In the present study the importance of adjuvants, their role and the effect of saponin in immune system is reviewed.

    Surgery still is the cornerstone of treatment for patients with stage II and III melanoma, but despite great efforts to gain or preserve locoregional control with excision of the primary tumour, satellites, intransits, sentinel node biopsy and lymphadenectomy, surgery alone does not seem to improve survival any further. Prognosis for patients with high risk melanoma remains poor with 5-year survival rates of 40 to 80%. Only interferon-2b has been approved as adjuvant therapy since 1995, but clinical integration is low considering the high risk-benefit ratio. In recent years systemic targeted- and immunotherapy have proven to be beneficial in advanced melanoma and could be a promising strategy for (neo)adjuvant treatment of patients with resectable high risk melanomas as well. Randomised, placebo- controlled phase III trials on adjuvant systemic targeted- and immunotherapy are currently being performed using new agents like ipilimumab, pembrolizumab, nivolumab, vemurafenib and dabrafenib plus trametinib. In this article we review the literature on currently known adjuvant therapies and currently ongoing trials of (neo)adjuvant therapies in high risk melanomas.

    Full Text Available A 46-year-old Korean woman was diagnosed with stage III breast cancer and underwent 8 cycles of neoadjuvant chemotherapy, breast conservation surgery and adjuvant radiotherapy. However, the cancer recurred in the right upper lung (RUL and the right pulmonary hilum after 8 months. The RUL nodule was removed through a wedge resection, and the pathologic finding was revealed as a metastatic adenocarcinoma. Adjuvant chemotherapy was recommended, but she refused it because she feared adverse reactions to chemotherapy. Instead, Korean Medicine Therapy with intravenous wild ginseng pharmacopuncture (WGP, Cordyceps sinensis pharmacopuncture, Trichosanthes kirilowii pharmacopuncture, Euonymus alatus pharmacopuncture (EAP and Astragalus membranaceus pharmacopuncture was started. After a month, the disease looked stable, but findings of newly occurring metastatic lymphadenopathies appeared on CT after 6 months. Salvage chemotherapy was recommended, but she also refused it. At this time, Prunella vulgaris pharmacopuncture was started. Finally, a complete resolution was confirmed on PET-CT after 5 months, and she has remained in stable condition for more than 6 months with WGP, EAP, a Soram nebulizer solution inhalation and the oral intake of Soramdan S and Hangamdan S.

Glucocorticoid binding to their designate glucocorticoid receptor (GR), sets off a plethora of cell-specific events including therapeutically desirable effects, such as cell death, as well as undesirable effects, including chemotherapy resistance, systemic side effects and glucocorticoid resistance. In this context, selective GR agonists and modulators (SEGRAMs) with a more restricted GR activity profile have been developed, holding promise for further clinical development in anti-inflammatory and potentially in cancer therapies. Thus far, the research into the prospective benefits of selective GR modulators in cancer therapy limped behind. Our review discusses how selective GR agonists and modulators could improve the therapy regimens for lymphoid malignancies, prostate or breast cancer. We summarize our current knowledge and look forward to where the field should move to in the future. Altogether, our review clarifies novel therapeutic perspectives in cancer modulation via selective GR targeting.

    Full Text Available Malignant glioma, or glioblastoma, is the most common and lethal form of brain tumor with a median survival time of 15 months. The established therapeutic regimen includes a tripartite therapy of surgical resection followed by radiation and temozolomide (TMZ chemotherapy, concurrently with radiation and then as an adjuvant. TMZ, a DNA alkylating agent, is the most successful antiglioma drug and has added several months to the life expectancy of malignant glioma patients. However, TMZ is also responsible for inducing lymphopenia and myelosuppression in malignant glioma patients undergoing chemotherapy. Although TMZ-induced lymphopenia has been attributed to facilitate antitumor vaccination studies by inducing passive immune response, in general lymphopenic conditions have been associated with poor immune surveillance leading to opportunistic infections in glioma patients, as well as disrupting active antiglioma immune response by depleting both T and NK cells. Deletion of O6-methylguanine-DNA-methyltransferase (MGMT activity, a DNA repair enzyme, by temozolomide has been determined to be the cause of lymphopenia. Drug-resistant mutation of the MGMT protein has been shown to render chemoprotection against TMZ. The immune modulating role of TMZ during glioma chemotherapy and possible mechanisms to establish a strong TMZ-resistant immune response have been discussed.

    Twenty-nine patients with locally advanced head and neck cancer were treated with twice-a-day fractionated radiotherapy (TDFR) for a total dose of 72 Gy to 82 Gy combined with Neo-adjuvant chemotherapy (NAC) of CDDP+5FU and concurrent chemotherapy of low dose CBDCA between 1994 and 1997. Twenty-one cases (72%) had complete response and sixteen cases recurred. The relapse-free rate at 2 years was 23.4% and the actual 2-year survival rate was 42.0%. No severe toxicity has been observed. Based on this investigation, it was concluded that TDFR with chemotherapy is a promising modality for locally advanced head and neck cancer and toxicity is acceptable. (author)

    Full Text Available Pemphigus vulgaris (PV is a life threatening autoimmune blistering disease of skin and mucous membranes. Advent of systemic steroids has greatly reduced the mortality rate. However, steroids and adjuvant immunosuppressive therapy are nowadays frequent contributory agents of morbidity and mortality of PV. Mycophenolate mofetil (MMF has been reported to be an effective adjuvant to systemic steroids. It helps in increasing the immunosuppressive effect and minimizing the toxicities by steroid sparing effect. However, its efficacy in refractory cases of PV is not well documented. The lowest possible dose with satisfactory therapeutic efficacy and least side effects is known. We used MMF 1 g/day and systemic steroids in 3 Indian patients with pemphigus vulgaris who were resistant to systemic steroid monotherapy or combination treatment with azathioprine. In our experience, MMF offers an effective adjuvant with minimal side-effects in the treatment of resistant PV.

    There are many reasons that lead to failure of cancer chemotherapy. Cancer has the ability to become resistant to many different types of drugs. Increased efflux of drug, enhanced repair/increased tolerance to DNA damage, high antiapoptotic potential, decreased permeability and enzymatic deactivation allow cancer cell survive the chemotherapy. Treatment can lead to the death of most tumor cells (drug-sensitive), but some of them (drug-resistant) survive and grow again. These tumor cells may arise from stem cells. There are many studies describing human experiments with multidrug resistance, especially in breast cancer. Unfortunately, studies of canine or feline ABC super family members are not as extensive as in human or mice and they are limited to several papers describing PGP in mammary cancer, cutaneous mast cell tumors and lymphoma. Multidrug resistance is one of the most significant problems in oncology today. The involvement of many different, not fully recognized, mechanisms in multidrug resistance of cancer cells makes the development of effective methods of therapy very difficult. Understanding the mechanisms of drug resistance in cancer cells may improve the results of treatment. This review article provides a synopsis of all aspects that refer to cancer cell resistance to antitumor drugs.

    OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage II breast cancer.METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage II, during the period of 1995 to 2001, were analyzed retrospectively. Among the patients, 47 were treated with neoadjuvant chemotherapy, and 66 received no adjuvant therapy before surgery (control group). After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen, the surgical procedure was conducted.RESULTS Complete remission (CR) was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission (PR) was reached for 22 cases. The rate of breast-conserving surgery was enhanced from 22.73% to 46.81% (P<0.05) in the neoadjuvant treatment group. There was no difference in the 5-year overall survival (OS) and disease-free survival (DFS) rate between the two groups (P>0.05), but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group (P<0.05).CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage II breast cancer and may improve the prognosis of the cases with clinical remission.

    Background Neoadjuvant chemotherapy has been used as a primary treatment for locally advanced or inflammatory breast cancer, and recently extended to operable breast cancer. However, only a few studies have published data concerning the outcomes of patients with stages Ⅱ and Ⅲ breast cancer after neoadjuvant chemotherapy. Methods This study retrospectively investigated the clinical value of neoadjuvant chemotherapy for patients with stages Ⅱ and Ⅲ breast cancer. The patients in Group 1 (n=54) were treated with neoadjuvant chemotherapy, followed by definitive surgery and adjuvant therapy. The patients in Group 2 (n=43) initially received definitive surgery, followed by adjuvant chemotherapy and other therapies. The operability rates for breast conservation and dermatoplasty were observed in Group 1 after neoadjuvant chemotherapy. After follow-up, the recurrence and overall and disease-free survival rates of the two groups were analyzed.Results Neoadjuvant chemotherapy increased the operability rates for breast conservation from 17.1% to 40.0% in stage Ⅱ (P=0.034) and 0% to 12.6% in stage Ⅲ (P=0.016), and decreased the dermatoplasty rates from 17.1% to 2.8% in stage Ⅱ (P=0.046) and 28.1% to 8.1% in stage Ⅲ (P=0.026). After a median follow-up of 46.8 months, there were 11 deaths and 13 recurrences in Group 1, and 15 deaths and 19 recurrences in Group 2. The overall and disease-free survival rates of stage Ⅲ disease were significantly higher in Group 1 than in Group 2 (68.4% vs 31.2%, P=0.028, and 63.2% vs 25.0%, P=0.024, respectively). There were no significant differences in the overall and disease-free survival rates of stage Ⅱ disease for Group 1 compared with Group 2 (85.7% vs 85.2%, P=0.953, and 80.6% vs 74.1%, P=0.400, respectively).Conclusions Neoadjuvant chemotherapy resulted in increased operability for breast conservation and decreased dermatoplasty. Neoadjuvant chemotherapy exhibited better recurrence control, and overall and disease

  20. Microbiota Influences Vaccine and Mucosal Adjuvant Efficacy

    2017-01-01

    A symbiotic relationship between humans and the microbiota is critical for the maintenance of our health, including development of the immune system, enhancement of the epithelial barrier, and acquisition of nutrients. Recent research has shown that the microbiota impacts immune cell development and differentiation. These findings suggest that the microbiota may also influence adjuvant and vaccine efficacy. Indeed, several factors such as malnutrition and poor sanitation, which affect gut microbiota composition, impair the efficacy of vaccines. Although there is little evidence that microbiota alters vaccine efficacy, further understanding of human immune system-microbiota interactions may lead to the effective development of adjuvants and vaccines for the treatment of diseases.

    Allergen-specific immunotherapy represents a curative treatment of type I allergies. Subcutaneous immunotherapy is conducted with allergens adsorbed on aluminum hydroxide or calcium phosphate particles, whereas sublingual immunotherapy relies on high doses of soluble allergen without any immunopotentiator. There is a potential benefit of adjuvants enhancing regulatory and Th1 CD4+T cell responses during specific immunotherapy. Molecules affecting dendritic cells favor the induction of T regulatory cell and Th1 responses and represent valid candidate adjuvants for allergy vaccines. Furthermore, the interest in viruslike particles and mucoadhesive particulate vector systems, which may better address the allergen(s) to tolerogenic antigen-presenting cells, is documented.

    A 42-year-old man was referred to our hospital for macrohematuria. Computer tomography and magnetic resonance imaging revealed right hydronephrosis and a retroperitoneal mass, located next to right side of the bladder. Cystoscopy showed a protruded lesion covered with normal mucosa at the right lateral wall. The patient underwent transurethral resection of the bladder tumor and biopsies of the bladder wall. Histological examination showed squamous cell carcinoma. Neoadjuvant chemotherapy using paclitaxel and carboplatin (TC) was performed. A total cystectomy, right nephroureterectomy and construction of the ileal conduit were performed after one course of systemic chemotherapy. Histological examination showed urothelial carcinoma with squamous cell differentiation. Unexpectedly, a small amount of CIS was detected only in the vicinity of the TUR scar. The patient received 2 cycles of TC chemotherapy as adjuvant chemotherapy. Unfortunately, 11 months later, local recurrence and liver metastasis were detected. He died 17 months after the surgery.

    Full Text Available Abstract We report here a 44-year-old Moroccan man with resectable gastric adenocarcinoma with overexpression of human epidermal growth factor receptor 2 (HER2 by immunohistochemistry who was treated with trastuzumab in combination with chemotherapy in perioperative setting. He received 3 cycles of neoadjuvant chemotherapy consisting of trastuzumab, oxaliplatin, and capecitabine. Afterwards, he received total gastrectomy with extended D2 lymphadenectomy without spleno-pancreatectomy. A pathologic complete response was obtained with a combination of trastuzumab and oxaliplatin and capecitabine. He received 3 more cycles of trastuzumab containing regimen postoperatively. We conclude that resectable gastric carcinoma with overexpression of the c-erbB-2 protein should ideally be managed with perioperative combination of trastuzumab with chemotherapy. Further research to evaluate trastuzumab in combination with chemotherapy regimens in the perioperative and adjuvant setting is urgently needed.

    Combined chemotherapy is used for the treatment of a number of malignancies such as breast cancer. The target of these antineoplastic agents is nuclear DNA, although it is not restricted to malignant cells. The aim of the present study was to assess DNA damage in peripheral blood lymphocytes (PBLs) of breast cancer patients subjected to combined adjuvant chemotherapy (5-fluorouracil, epirubicin and cyclophosphamide, FEC), using a modified comet assay to detect DNA single-strand breaks (SSB) and double-strand breaks (DSB). Forty-one female patients with advanced breast cancer before and after chemotherapy and 60 healthy females participated in the study. Alkaline and neutral comet assays were performed in PBLs according to a standard protocol, and DNA tail moment was measured by a computer-based image analysis system. Breast cancer patients before treatment had higher increased background levels of SSB and DSB as compared to healthy women. During treatment, a significant increase in DNA damage was observed after the 2nd cycle, which persisted until the end of treatment. Eighty days after the end of treatment the percentage of PBLs with SSB and DSB remained elevated, but the magnitude of DNA damage (tail moment) returned to baseline levels. There was no correlation between PBL DNA damage and response to chemotherapy. DNA-SSB and DSB in PBLs are present in cancer patients before treatment and increase significantly after combined chemotherapy. No correlation with response to adjuvant chemotherapy was found. Biomonitoring DNA damage in PBLs of cancer patients could help prevent secondary effects and the potential risks of developing secondary cancers.

We analyzed the outcome of PGS patients treated with concurrent and adjuvant temozolomide (TMZ. SETTINGS AND DESIGN: Retrospective single institutional analysis. MATERIALS AND METHODS: We retrospectively evaluated 27 patients of PGS treated with radiotherapy (RT and TMZ during 2007-2012. STATISTICAL ANALYSIS USED: Overall survival (OS was estimated by the use of Kaplan Meier method and toxicities were evaluate using common terminology criteria for adverse events version 2.0 (National Cancer Institute, USA. RESULTS: Median age at presentation and Karnofsky performance status was 45 years and 90 respectively and male: female ratio was 20:7. Patients received adjuvant RT to a total dose of 60 Gy at 2 Gy/fraction. All patients except 5 received adjuvant TMZ to a median number of 6 cycles. Grade 2 and 3 hematological toxicity was seen in 8% and 4% of patients respectively during concurrent RT. During adjuvant chemotherapy, 13.6% had Grade 3 thrombocytopenia and 9.5% had Grade 3 neutropenia. Median OS was 16.7 months (1 year and 2 year actuarial OS was 70.8% and 32.6% respectively. Adjuvant TMZ was associated with a better survival (median survival 21.21 vs. 11.93 months; P = 0.0046 on univariate analysis and also on multivariate analysis (hazard ratio 1.82, 95% confidence interval: 1.503-25.58; P = 0.012. CONCLUSIONS: The results of our study, largest series of patients with PGS treated with concurrent and adjuvant TMZ shows an impressive survival with acceptable toxicity. We suggest TMZ be included in the “standard of care” for this tumor.

    OBJECTIVE To evaluate the 10-year curative effects of short-term intensive neoadjuvant chemotherapy for operable breast cancer. METHODS A total of 510 patients with stagell and operable stagelll breast cancer were divided into group A (preoperative neoadjuvant chemotherapy 251 cases) and group B (postoperative adjuvant chemotherapy 259 cases). The patients in group A received short-term and intensive neoadjuvant chemotherapy for 4 weeks followed by modified radical mastectomy two weeks after the chemotherapy. The postoperative adjuvant chemotherapy began within two weeks after surgery. The same chemotherapeutic regimen was used for both groups. RESULTS For stage Ⅲ in group A the 5-year overall survival rate (OS) and disease-free survival rate (DFS) were 59.2% and 54.9% respectively which were higher than those in group B (28.3% and 20.8% respectively, P<0.05). The 10-year OS and DFS were 78.1% and 73.5% respectively for stage Ⅱ in group A which were higher than those in group B (68.4% and 60.7%, P<0.05). The 10-year OS and DFS were 42.3% and 40.4% respectively forstage Ⅲ in group A which were higher than those in group B (20.4% and 18.4% respectively, P<0.05). CONCLUSION The results showed that intensive neoadjuvant chemotherapy can improve the 10-year survival for patients with stage Ⅱ and operablestage Ⅲ breast cancer.

    Full Text Available Abstract Background Mucinous neoplasms within the abdomen may disseminate by direct extension through the diaphragm to involve the pleural space. Treatment of this condition is by parietal and visceral pleurectomy followed by hyperthermic intrapleural chemotherapy. Case presentation In this case report a patient developed persistent right upper lobe interstitial pneumonitis and progressive parenchymal fibrosis following intrapleural chemotherapy treatment with mitomycin C and doxrubicin. The condition persisted until death 28 months later. Death was from progressive intraabdominal disease with intestinal obstruction and sepsis associated with progressive pulmonary parenchymal disease. The right pleural space disease did not recur. Conclusion This manuscript is the first case report describing interstitial pneumonitis and lung fibrosis following intrapleural chemotherapy. Since pulmonary toxicity from chemotherapy is a dose-dependent phenomenon, dose reduction of intrapleural as compared to intraperitoneal hyperthermic chemotherapy may be necessary.

    OBJECTIVE The breast cancer lack of expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) is defined as the Triple-negative breast cancer (TNBC). Our purpose is to compare the response and long-term effect of the TNBC and non-TNBC patients receiving neo-adjuvant anthracycline-based chemotherapy, and to investigate the mechanisms of TNBC affecting the survivals. METHODS Data of long-term follow-up (median, 5.4 years) of 326 patients who received neo-adjuvant chemotherapy with anthracycline-based regimen, during a period from 2000 to 2003, were analyzed. Expressions of ER, PR, HER-2, P53, Ki-67 and E-cadherin were determined using immunohistochemical staining method. A multivariate Cox regression analysis was used to analyze independent prognostic factors affecting the relapse-free survival (RFS) and overall survival (OS) rates. Clinical effects of the neo-adjuvant anthracycline-based chemotherapeutic regimen and the RFS and OS rates were compared between the patients with TNBC and non-TNBC, and the correlations among the triple- negative phenotype (TNP), tumor grading and the expressions of P53, Ki-67 and E-cadherins were analyzed. RESULTS TNP, TNM staging, histological grades, clinical response of the neo-adjuvant chemotherapy and pathological complete remission (pCR) rate were the independent prognostic factors affecting the survival rates. Furthermore, 70 (21.5%) of the 326 patients suffered TNBC. Compared with the subjects in non- TNBC group, the patients with TNBC had a significantly higher pCR rate (P=0.046) and clinical response rate (P=0.037), but also decreased 5-year RFS (P=0.001) and OS (P=0.004) rates. The RFS and OS rates were not improved in the TNBC patients who achieved a clinical remission after the neo-adjuvant chemotherapy. The triple-negative phenotype was positively correlated with the level of P53, Ki-67 expression (P=0.007, P=0.028), but negatively correlated with level of

    2009-01-01

    Full Text Available The incidence of gliomas is increasing worldwide, including India. Of the 18,820 new cases of primary central nervous system (CNS tumors diagnosed annually in the United States, gliomas account for over 60% with 30-40% of them being glioblastoma multiforme (GBM, 10% being anaplastic astrocytoma (AA, and 10% being low grade gliomas (LGGs. This is in contrast to one study from West Bengal, India, in which only 7.9% of the brain tumors were GBMs, while 46.8% were astrocytomas. Of all adult primary CNS tumors, GBM is the most common and the most malignant with about 7,000 to 8,000 new cases annually in the United States. Given poor outcomes, a number of treatment approaches have been investigated. Common to these approaches is the use of adjuvant radiation therapy, even as surgery alone, with or without chemotherapy, may be the mainstay for some lower grade and low-risk gliomas. Today, treatment typically involves external beam radiation, with concurrent and adjuvant chemotherapy for more aggressive histologies. Although gliomas are relatively uncommon, active research is ongoing. Results of landmark trials along with some of the recently published trials are presented. These trials and management strategies as well as evolving concepts are found by reviewing over 200 articles in the National Library Medical (NLM database, PubMed, more than 60 of which are refrenced. Specifically, the database is searched using the following keywords, with various combinations: glioma, low-grade, anaplastic, astrocytoma, oligodendroglioma, oligoastrocytoma, glioblastoma multiforme, chemotherapy, radiation, new concepts, phase III, MGMT, CDX-110 (Celldex, temozolomide, 1p/19q deletion, and bevacizumab.

    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.

    Our previous studies have demonstrated that Fam20C promotes differentiation and mineralization of odontoblasts, ameloblasts, osteoblasts and osteocytes during tooth and bone development. Ablation of the Fam20C gene inhibits bone and tooth growth by increasing fibroblast growth factor 23 in serum and causing hypophosphatemia in conditional knockout mice. However, control and regulation of the expression of Fam20C are still unknown. In this study, we generated a transgenic reporter model which expresses green fluorescence protein (GFP) driven by the Fam20C promoter. Recombineering was used to insert a 16 kb fragment of the mouse Fam20C gene (containing the 15 kb promoter and 1.1 kb of exon 1) into a pBluescript SK vector with the topaz variant of GFP and a bovine growth hormone polyadenylation sequence. GFP expression was subsequently evaluated by histomorphometry on cryosections from E14 to adult mice. Fluorescence was evident in the bone and teeth as early as E17.5. The GFP signal was maintained stably in odontoblasts and osteoblasts until 4 weeks after birth. The expression of GFP was significantly reduced in teeth, alveolar bone and muscle by 8 weeks of age. We also observed colocalization of the GFP signal with the Fam20C antibody in postnatal 1-and 7-day-old animals. Successful generation of Fam20C-GFP transgenic mice will provide a unique model for studying Fam20C gene expression and the biological function of this gene during odontogenesis and osteogenesis.

  17. Methotrexate Toxicity in Growing Long Bones of Young Rats: A Model for Studying Cancer Chemotherapy-Induced Bone Growth Defects in Children

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The advancement and intensive use of chemotherapy in treating childhood cancers has led to a growing population of young cancer survivors who face increased bone health risks. However, the underlying mechanisms for chemotherapy-induced skeletal defects remain largely unclear. Methotrexate (MTX, the most commonly used antimetabolite in paediatric cancer treatment, is known to cause bone growth defects in children undergoing chemotherapy. Animal studies not only have confirmed the clinical observations but also have increased our understanding of the mechanisms underlying chemotherapy-induced skeletal damage. These models revealed that high-dose MTX can cause growth plate dysfunction, damage osteoprogenitor cells, suppress bone formation, and increase bone resorption and marrow adipogenesis, resulting in overall bone loss. While recent rat studies have shown that antidote folinic acid can reduce MTX damage in the growth plate and bone, future studies should investigate potential adjuvant treatments to reduce chemotherapy-induced skeletal toxicities.

    A number of adjuvant formulations were assayed in mice immunized with 3.75 µg of A/California/7/2009 (H1N1) pdm09 influenza vaccine with vitamins A, D and/or E in emulsions or B2 and/or B9 combined with Bordetella pertussis MPLA and/or alum as adjuvants. Squalene was used as positive control, as well as MPLA with alum. The immune response was evaluated by a panel of tests, including a hemagglutination inhibition (HAI) test, ELISA for IgG, IgG1, and IgG2a and IFN-γ, IL-2, IL-6 and IL-10 quantification in splenocyte culture supernatant after stimulus with influenza antigen. Immunological memory was evaluated using a 1/10 dose booster 60 days after the first immunization followed by assessment of the response by HAI, IgG ELISA, and determination of the antibody affinity index. The highest increases in HAI, IgG1 and IgG2a titers were obtained with the adjuvant combinations containing vitamin E, or the hydrophilic combinations containing MPLA and alum or B2 and alum. The IgG1/IgG2a ratio indicates that the response to the combination of B2 with alum would have more Th2 character than the combination of MPLA with alum. In an assay to investigate the memory response, a significant increase in HAI titer was observed with a booster vaccine dose at 60 days after immunization with vaccines containing MPLA with alum or B2 with alum. Overall, of the 27 adjuvant combinations, MPLA with alum and B2 with alum were the most promising adjuvants to be evaluated in humans.

The latest generation of endocrine therapy for breast cancer,aromatase inhibitors, has proved superior to tamoxifen in terms of toxicity and efficacy in the adjuvant setting.Compared with neo-adjuvant chemotherapy, the appropriate patients to receive nco-adjuvant endocrine therapy can achieve similar short-term benefit. However, because of fewer long-term follow up results, the overall prognosis is not clear.

    Adjuvant chemotherapy regime for ovarian cancer patients remains to be a contentious issue. The aim of this study was to compare the overall and progression-free survival of women with ovarian cancer before and after introduction of paclitaxel in our unit in 1992. A sample of 112 women who received adjuvant therapy following surgery for ovarian cancer was collected, 68 (61%) received platinum+alkylating agent before 1992 and later 44 (39%) received platinum+paclitaxel. Five-year survival was same in both treatment groups when there was no macroscopic disease after surgery (78% versus 70%) and when residual disease was <2 cm (50% versus 40%). Survival was greater in women with residual disease >2 cm in the platinum+paclitaxel group (50% versus 24%), (p = 0.04). However, progression-free survival was similar in both groups irrespective of stage or residual volume of disease. Therefore consideration to selective use of paclitaxel could reduce patient morbidity and costs significantly.

    The results of a prospective randomized study of 46 patients with breast carcinoma are presented. Twenty six patients were treated with AM3 (biological response modifier) associated with adjuvant radiotherapy and chemotherapy. Bone marrow hypoplasia was observed in 26.9% of the patients treated with AM3 compared with a 65% incidence in the control group (P less than 0.05). All patients showed leukopenia in peripheral blood count; however, the nadir of leukocytes was 4,000 leu/mm3 in the test group, compared with 1,900 leu/mm3 in the control group. None of the patients in the AM3 group showed thrombocytopenia, whereas 55% in the control group did. In none of the AM-3-treated cases was it necessary to modify the therapeutic schedule of adjuvant treatment.

    The invasive nature of glioblastoma (GBM) represents a major clinical challenge contributing to poor outcomes. Invasion of GBM into healthy tissue restricts chemotherapeutic access and complicates surgical resection. Here, we test the hypothesis that an effective anti-invasive agent can "contain" GBM and increase the efficacy of chemotherapy. We report a new anti-invasive small molecule, Imipramine Blue (IB), which inhibits invasion of glioma in vitro when tested against several models. IB inhibits NADPH (reduced form of nicotinamide adenine dinucleotide phosphate) oxidase-mediated reactive oxygen species generation and alters expression of actin regulatory elements. In vivo, liposomal IB (nano-IB) halts invasion of glioma, leading to a more compact tumor in an aggressively invasive RT2 syngeneic astrocytoma rodent model. When nano-IB therapy was followed by liposomal doxorubicin (nano-DXR) chemotherapy, the combination therapy prolonged survival compared to nano-IB or nano-DXR alone. Our data demonstrate that nano-IB-mediated containment of diffuse glioma enhanced the efficacy of nano-DXR chemotherapy, demonstrating the promise of an anti-invasive compound as an adjuvant treatment for glioma.

    Full Text Available Abstract Background The molecular characteristics associated with the response to treatment in glioblastomas (GBMs remain largely unknown. We performed a retrospective study to assess the genomic characteristics associated with the response of GBMs to either first-line chemotherapy or radiation therapy. The gene expression (n = 56 and genomic profiles (n = 67 of responders and non-responders to first-line chemotherapy or radiation therapy alone were compared on Affymetrix Plus 2 gene expression arrays and BAC CGH arrays. Results According to Verhaak et al.'s classification system, mesenchymal GBMs were more likely to respond to radiotherapy than to first-line chemotherapy, whereas classical GBMs were more likely to respond to first-line chemotherapy than to radiotherapy. In patients treated with radiation therapy alone, the response was associated with differential expression of microenvironment-associated genes; the expression of hypoxia-related genes was associated with short-term progression-free survival ( 10 months. Consistently, infiltration of the tumor by both CD3 and CD68 cells was significantly more frequent in responders to radiotherapy than in non-responders. In patients treated with first-line chemotherapy, the expression of stem-cell genes was associated with resistance to chemotherapy, and there was a significant association between response to treatment and p16 locus deletions. Consistently, in an independent data set of patients treated with either radiotherapy alone or with both radiotherapy and adjuvant chemotherapy, we found that patients with the p16 deletion benefited from adjuvant chemotherapy regardless of their MGMT promoter methylation status, whereas in patients without the p16 deletion, this benefit was only observed in patients with a methylated MGMT promoter. Conclusion Differential expression of microenvironment genes and p16 locus deletion are associated with responses to radiation therapy and to first

    Adjuvants are an essential component of modern vaccine development. Despite many decades of development, only a few types of adjuvants are currently included in vaccines approved for human use. In order to better understand the reasons that development of some adjuvants succeeded while many others failed, we discuss some of the common attributes of successful first generation adjuvants. Next, we evaluate current trends in the development of second generation adjuvants, including the potential advantages of rationally designed synthetic immune potentiators appropriately formulated. Finally, we discuss desirable attributes of next generation adjuvants. Throughout, we emphasize that the importance of formulation and analytical characterization in all aspects of vaccine adjuvant development is often underappreciated. We highlight the formulation factors that must be evaluated in order to optimize interactions between vaccine antigens, immune potentiators, and particulate formulations, and the resulting effects on safety, biological activity, manufacturability, and stability.

    Full Text Available Abstract Background Hematopoiesis is a complex developmental process controlled by a large number of factors that regulate stem cell renewal, lineage commitment and differentiation. Secreted proteins, including the hematopoietic growth factors, play critical roles in these processes and have important biological and clinical significance. We have employed representational difference analysis to identify genes that are differentially expressed during experimentally induced myeloid differentiation in the murine EML hematopoietic stem cell line. Results One identified clone encoded a previously unidentified protein of 541 amino acids that contains an amino terminal signal sequence but no other characterized domains. This protein is a member of family of related proteins that has been named family with sequence similarity 20 (FAM20 with three members (FAM20A, FAM20B and FAM20C in mammals. Evolutionary comparisons revealed the existence of a single FAM20 gene in the simple vertebrate Ciona intestinalis and the invertebrate worm Caenorhabditis elegans and two genes in two insect species, Drosophila melanogaster and Anopheles gambiae. Six FAM20 family members were identified in the genome of the pufferfish, Fugu rubripes and five members in the zebrafish, Danio rerio. The mouse Fam20a protein was ectopically expressed in a mammalian cell line and found to be a bona fide secreted protein and efficient secretion was dependent on the integrity of the signal sequence. Expression analysis revealed that the Fam20a gene was indeed differentially expressed during hematopoietic differentiation and that the other two family members (Fam20b and Fam20c were also expressed during hematcpoiesis but that their mRNA levels did not vary significantly. Likewise FAM20A was expressed in more limited set of human tissues than the other two family members. Conclusions The FAM20 family represents a new family of secreted proteins with potential functions in regulating

    Full Text Available Breast cancer (BC is one of the leading cause of death in developed Countries and every year more than a million new cases are diagnosed worldwide. In Italy the prevalence of BC was estimated to be 1,070 per 100,000 at 31 December 1992. Nevertheless, despite the increase in incidence, mortality rate for BC are decreased in the last decades probably due to several factors such as implementation of screening programs, early diagnosis and new adjuvant therapies. Important types of adjuvant chemotherapy include anthracyclines and taxanes and these treatments continue to be evaluated to determine optimal combinations and dosing regimens. The efficacy of paclitaxel and docetaxel in adjuvant setting for the treatment of early BC has been assessed in different trials where the two taxanes showed a significant increase in both Disease Free Survival (DFS and Overall Survival (OS in comparison with nontaxane therapy. In particular results from one of the last studies comparing paclitaxel and docetaxel show equivalent efficacy for both drugs. At the light of the recent findings, the objective of this work is to perform a cost minimization analysis of paclitaxel vs docetaxel in the adjuvant setting for treatment of early BC in Italy. The analysis was conducted from the National Health Service’s point of view, assuming equivalent efficacy in terms of DFS and OS for both taxanes. Costs were evaluated on the basis of therapeutic schemes used in the analyzed trials. Results show that paclitaxel, administered every 3 weeks for 4 cycles after doxorubicin and cyclophosphamide, represents the less costly therapy. This is a conservative costs estimate based on data from literature that does not take into account possible additional costs associated to the treatment of febrile neutropenia (FN as adverse event related to chemotherapy. Since, on the basis of scientific literature data, FN seems to be more related with docetaxel than with paclitaxel administration, it

    M. Yu. Fedyanin

    2016-01-01

    Full Text Available Metronomic chemotherapy implies the regular use of cytotoxic agents in doses much smaller than the maximum tolerable doses for a long time. Preclinical experiments show that this treatment option has a many-sided (antiangiogenic, immunostimulating, and direct cytotoxic effect on tumor. Moreover, this approach has gained the widest acceptance in treating patients with metastatic breast cancer in clinical practice. By taking into account the high activity of angiogenesis in colon cancer progression, it is interesting to study the impact of metronomic chemotherapy regimens for this nosological entity as well. This literature review considers not only the history of metronomic chemotherapy, the mechanisms of action, and a range of drugs having an antitumor effect in the metronomic regimens, but also analyzes clinical trials of metronomic chemotherapy regimens in patients with metastatic colon cancer.

    Full Text Available Breast cancer currently is a major health problem among women worldwide accounting for around 13.7% cancer deaths, nearly 1/3rd of it being due to Locally advanced breast cancer (LABC. Despite progress achieved in diagnosis & therapy of Breast cancer, LABC remains a major clinical challenge and in efforts to increase pCR, CCR & DFS in LABC, Neoadjuvant or primary chemotherapy followed by locoregional therapy and adjuvant systemic CT is well accepted treatment strategy since last 3 decades. Further to address the issue of drug resistance in NACT sequential anthracycline-taxane NACT has been evaluated by many researchers and has resulted in better outcome in terms of overall survival and pCR. In this study we have evaluated 4 cycles of sequential anthracycline-taxane, 2 cycles of Cyclophosphamide, Epirubicin, Fluracil +2 cycles of Docetaxel, Epirubicin (CEF- DE NACT in a series of 10 cases of ER/PR +ve, Her -2 neu negative patients of LABC. 9/10 cases were rendered operable after primary chemotherapy and were subjected to further 4 cycles of adjuvant chemotherapy (1 cycle CEF, 1 cycle DE, 2cycles single agent Docetaxel, followed by locoregional RT. This tailored sequential NACT protocol in our subgroup of patient was well tolerated, well accepted and resulted in substantial increase in operability with CCR & DFS in 6/10 cases on 3 years follow up and pCR in one patient. Sequential NACT needs further validation by more RCT with extensive follow up

    Full Text Available Hepatoblastoma with intraatrial tumor thrombus is relatively rare. We report a case of hepatoblastoma with tumor thrombus extending into the right atrium, which responded well to chemotherapy and was resected using extracorporeal circulation. A 4-year-old girl was referred to our hospital because of abdominal distention and tenderness. A computed tomography (CT scan showed a large tumor occupying the left 3 segments of the liver with tumor thrombus extending into the right atrium. There was also a small intrahepatic metastasis in the right lobe of the liver. She was diagnosed with hepatoblastoma on the basis of the results of open biopsy. Neoadjuvant chemotherapy with an intense CDDP-based regimen was performed. The tumor responded well to chemotherapy, and intrahepatic metastasis became undetectable on CT scan, although the tumor thrombus remained in the right atrium. After 7 courses of chemotherapy, we performed resection using extracorporeal circulation. The postoperative course was uneventful, and adjuvant chemotherapy was started 10 days after the operation. Her serum alpha-fetoprotein (AFP level decreased to the normal range, and she was free of disease for 1 year after the operation. Tumor resection using extracorporeal circulation can be performed safely and is justified in patients with intraatrial tumor thrombus.

    Purpose: The optimal sequence of radiotherapy and chemotherapy in breast-conserving therapy is unknown. Methods and Materials: From 1983 through 2007, a total of 641 patients with 653 instances of breast-conserving therapy (BCT), received both chemotherapy and radiotherapy and are the basis of this analysis. Patients were divided into three groups. Groups A and B comprised patients treated before 2005, Group A radiotherapy first and Group B chemotherapy first. Group C consisted of patients treated from 2005 onward, when we had a fixed sequence of radiotherapy first, followed by chemotherapy. Results: Local control did not show any differences among the three groups. For distant metastasis, no difference was shown between Groups A and B. Group C, when compared with Group A, showed, on univariate and multivariate analyses, a significantly better distant metastasis-free survival. The same was noted for disease-free survival. With respect to disease-specific survival, no differences were shown on multivariate analysis among the three groups. Conclusion: Radiotherapy, as an integral part of the primary treatment of BCT, should be administered first, followed by adjuvant chemotherapy.

    2014-04-01

    Full Text Available OBJECTIVES: to identify the prevalence, and describe the management of, neutropenia throughout the chemotherapy treatment among women with breast cancer.METHODS: observational study, cycles of chemotherapy. 116 neutropenic events were recorded, and 63.3% of the patients presented neutropenia at some point of their treatment, 46.5% of these presenting grade II. The management used was temporary suspension between the cycles and the mean number of delays was 6 days. The study was prospective and longitudinal, where the evaluation of the hematological toxicities was undertaken at each cycle of chemotherapy, whether neoadjuvant or adjuvant.RESULTS: 79 women were included, who received 572 cycles. However, the reasons for the suspensions were the lack of a space in the chemotherapy center, followed by neutropenia.CONCLUSION: neutropenia is one of the most common and serious adverse events observed during the chemotherapy. Nursing must invest in research regarding this adverse event and in management strategies for organizing the public health system, so as to offer quality care.

    The EndoPredict (EP) signature is a prognostic 11-gene expression signature specifically developed in ER+/HER2- node-negative/positive breast cancer. It is associated with relapse-free survival in patients treated with adjuvant hormone therapy, suggesting that EP low-risk patients could be treated with adjuvant hormone therapy alone whereas high-risk patients would deserve addition of adjuvant chemotherapy. Thus, it is important to determine whether EP high-risk patients are or are not more sensitive to chemotherapy than low-risk patients. Here, we have assessed the EP predictive value for pathological complete response to neoadjuvant chemotherapy in ER+/HER2- breast cancer. We gathered gene expression and histoclinical data of 553 pre-treatment ER+/HER2- breast carcinomas treated with anthracycline-based neoadjuvant chemotherapy. We searched for correlation between the pathological complete response (pCR) and the EP score-based classification. The overall pCR rate was 12%. Fifty-one percent of samples were classified as low-risk according to the EP score and 49% as high-risk. EP classification was associated with a pCR rate of 7% in the low-risk group and 17% in the high-risk group (p < 0.001). In multivariate analysis, the EP score remained significantly associated with pCR. Many genes upregulated in the high-risk tumours were involved in cell proliferation, whereas many genes upregulated in the low-risk tumours were involved in ER-signalling and stroma. Despite higher chemosensitivity, the high-risk group was associated with worse disease-free survival. In conclusion, EP high-risk ER+/HER2- breast cancers are more likely to respond to anthracycline-based chemotherapy.

    Background The importance of polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene for the prediction of the response to fluorouracil-based adjuvant chemotherapy in gastric cancer patients remains unclear.The aim of this study is to assess the predictive value of several polymorphisms of the MTHFR gene for clinical outcomes of gastric cancer patients treated with fluorouracil-based adjuvant chemotherapy in Chinese population.Methods Three hundred and sixty-two Chinese patients with gastric cancer were treated with fluorouracil-based adjuvant chemotherapy.DNA samples were isolated from peripheral blood collected before treatment.The three single nucleotide polymorphisms (SNPs) (rs1801131,rs1801133,rs2274976) genotypes of the MTHFR gene were determined by matrixassisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).Results The average response rate for chemotherapy was 46.7%.Homozygous genotypes rs2274976G/G (x2=22.7,P <0.01) and rs1801131A/A (x2=14.3,P=0.008) were over-represented in responsive patients.Carriers of the rs2274976A allele genotypes (G/A and A/A) and of the rs1801131C allele genotypes (A/C and C/C) were prevalent in nonresponsive patients.In the haplotype association analysis,there was a significant difference in global haplotype distribution between the groups (x2=20.69,P=0.000 124).Conclusions These results suggest that polymorphisms of the MTHFR gene may be used as predictors of the response to fluorouracil-based chemotherapy for gastric cancer patients in Chinese population.Well-designed,comprehensive,and prospective studies on determining these polymorphisms of MTHFR gene as clinical markers for predicting the response to fluorouracil-based therapy in gastric cancer patients is warranted.

    Aluminum-adjuvanted vaccines are administered through an intramuscular injection (IM) in the US and EU, however, a subcutaneous injection (SC) has been recommended in Japan because of serious muscle contracture previously reported following multiple IMs of antibiotics. Newly introduced adjuvanted vaccines, such as the human papillomavirus (HPV) vaccines, have been recommended through IM. In the present study, currently available vaccines were evaluated through IM in mice. Aluminum-adjuvanted vaccines induced inflammatory nodules at the injection site, which expanded into the intra-muscular space without any muscle degeneration or necrosis, whereas non-adjuvanted vaccines did not. These nodules consisted of polymorph nuclear neutrophils with some eosinophils within the initial 48h, then monocytes/macrophages 1 month later. Inflammatory nodules were observed 6 months after IM, had decreased in size, and were absorbed 12 months after IM, which was earlier than that after SC. Cytokine production was examined in the injected muscular tissues and AS04 adjuvanted HPV induced higher IL-1β, IL-6, KC, MIP-1, and G-CSF levels in muscle tissues than any other vaccine, but similar serum cytokine profiles were observed to those induced by the other vaccines. Currently available vaccines did not induce muscular degeneration or fibrotic scar as observed with muscle contracture caused by multiple IMs of antibiotics in the past.

    -line treatment in metastatic or unresectable GISTs, changing the outcome of this disease in relation to the benefits obtained previously with cancer chemotherapy. METHODS: Was performed a literature review with consultation in Medline/Pubmed, Lilacs and Scielo crossing the key words: gastrointestinal stromal tumor, GIST, treatment, adjuvant treatment. In addition to this review was added to the authors' personal experience. CONCLUSION: Better refinement of prognostic criteria is allowed to select the most appropriate patients for adjuvant treatment with imatinib. The results are yet evident on basis of one year, which produces significant benefit in relapse-free survival but not overall survival in these patients.

    Purpose: To determine the impact of chemoradiation therapy (CRT) on overall survival (OS) after resection of pancreatic adenocarcinoma. Methods and Materials: A multicenter retrospective review of 955 consecutive patients who underwent complete resection with macroscopically negative margins (R0-1) for invasive carcinoma (T1-4; N0-1; M0) of the pancreas was performed. Exclusion criteria included metastatic or unresectable disease at surgery, macroscopic residual disease (R2), treatment with intraoperative radiation therapy (IORT), and a histological diagnosis of no ductal carcinoma, or postoperative death (within 60 days of surgery). In all, 623 patients received postoperative radiation therapy (RT), 575 patients received concurrent chemotherapy (CT), and 462 patients received adjuvant CT. Results: Median follow-up was 21.0 months. Median OS after adjuvant CRT was 39.9 versus 24.8 months after no adjuvant CRT (P<.001) and 27.8 months after CT alone (P<.001). Five-year OS was 41.2% versus 24.8% with and without postoperative CRT, respectively. The positive impact of CRT was confirmed by multivariate analysis (hazard ratio [HR] = 0.72; confidence interval [CI], 0.60-0.87; P=.001). Adverse prognostic factors identified by multivariate analysis included the following: R1 resection (HR = 1.17; CI = 1.07-1.28; P<.001), higher pT stage (HR = 1.23; CI = 1.11-1.37; P<.001), positive lymph nodes (HR = 1.27; CI = 1.15-1.41; P<.001), and tumor diameter >20 mm (HR = 1.14; CI = 1.05-1.23; P=.002). Multivariate analysis also showed a better prognosis in patients treated in centers with >10 pancreatic resections per year (HR = 0.87; CI = 0.78-0.97; P=.014) Conclusion: This study represents the largest comparative study on adjuvant therapy in patients after resection of carcinoma of the pancreas. Overall survival was better in patients who received adjuvant CRT.

    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

  9. Pulmonary Fibrosis Secondary to FOLFOX Chemotherapy: A Case Report

    Wai Cheong Soon

    2014-09-01

    Full Text Available A 54-year-old female presented with a 2-week history of increasing shortness of breath and fever. She had a history of a poorly differentiated sigmoid adenocarcinoma for which she underwent an anterior resection 6 months prior to admission, followed by 12 cycles of adjuvant FOLFOX chemotherapy. The patient was treated for a severe community-acquired pneumonia; however, she remained hypoxic. A chest CT revealed extensive right-sided fibrotic changes, tractional dilatation of the airways and ground glass density, which had developed since a staging CT scan performed 2 months previously. Although her symptoms improved with steroid therapy, repeat imaging revealed that right hydropneumothorax had developed, and this required the insertion of a chest drain. Following its successful removal, the patient continues to improve clinically and radiographically. The rapid onset and nature of these changes is consistent with a drug-induced fibrotic lung disease secondary to FOLFOX chemotherapy. The phenomenon is underreported and yet, it is relatively common: it occurs in approximately 10% of patients who are treated with antineoplastic agents, although information specifically relating to FOLFOX-induced pulmonary toxicity is limited. It is associated with significant morbidity and mortality, but is often hard to differentiate from other lung conditions, making the diagnosis a challenge. Pulmonary toxicity is an important complication associated with antineoplastic agents. It should be considered in any patient on a chemotherapeutic regimen who presents with dyspnoea and hypoxia in order to try to reduce the associated morbidity and mortality.

    Canine hemangiosarcoma (HSA) is a highly malignant tumor for which standard chemotherapy has done little to substantially improve survival. Cyclooxygenase-2 (Cox-2) plays a role in the formation, growth, and metastasis of tumors and inhibitors have demonstrated therapeutic benefit with certain canine cancers. In this prospective study, 21 dogs received adjuvant therapy combining the selective Cox-2 inhibitor deracoxib with doxorubicin, following splenectomy for HSA. The combination was well-tolerated with only low-grade gastrointestinal and hematologic toxicities noted. An overall median survival of 150 days (range; 21 to 1506 days) was noted. Although there was no significant difference in survival based upon stage of disease, dogs with stage III HSA (n = 11) had a median survival of 149 days, which appears to be longer than previously reported. Further studies are warranted to evaluate the potential benefit of Cox-2 inhibitors in the treatment of canine HSA.

    Background Ovarian function suppression (OFS) significantly downregulates the concentration of plasma estrogens. However, it is unclear whether it offers any survival benefits if combined with adjuvant tamoxifen treatment in premenopausal women. This meta-analysis was designed to assess data from previous studies involving adjuvant tamoxifen treatment plus OFS in premenopausal breast cancer. Methods Electronic literature databases (PubMed, Embase, the Web of Science, and the Cochrane Library) were searched for relevant randomized controlled trials published prior to February 1, 2015. Only randomized controlled trials that compared tamoxifen alone with tamoxifen plus OFS for premenopausal women with breast cancer were selected. The evaluated endpoints were disease-free survival and overall survival. Results Four randomized controlled trials comprising 6,279 patients (OFS combination, n=3,133; tamoxifen alone, n=3,146) were included in the meta-analysis. There was no significant improvement in disease-free survival or overall survival with addition of OFS in either the whole population or the hormone receptor-positive subgroup. The risk of distant recurrence was not reduced with the addition of OFS in the whole population. A subgroup analysis showed that addition of OFS significantly improved overall survival in patients who were administered chemotherapy. Conclusion Based on the available studies, concurrent administration of OFS and adjuvant tamoxifen treatment for premenopausal women with breast cancer has no effect on prolonging disease-free survival and overall survival, excluding patients who were administered chemotherapy. It should not be widely recommended, except perhaps for women who were hormone-receptor positive and who were also administered adjuvant chemotherapy. PMID:26109867

    ABSTRACT Adjuvants are substances added to vaccines to improve their immunogenicity. Used for more than 80 years, aluminum, the first adjuvant in human vaccines, proved insufficient to develop vaccines that could protect against new challenging pathogens such as HIV and malaria. New adjuvants and new combinations of adjuvants (Adjuvant Systems) have opened the door to the delivery of improved and new vaccines against re-emerging and difficult pathogens. Adjuvant Systems concept started through serendipity. The access to new developments in technology, microbiology and immunology have been instrumental for the dicephering of what they do and how they do it. This knowledge opens the door to more rational vaccine design with implications for developing new and better vaccines. PMID:27636098

    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.

    Full Text Available Pooja Advani,1 Lauren Cornell,2 Saranya Chumsri,1 Alvaro Moreno-Aspitia1 1Division of Hematology and Oncology, 2Department of Internal Medicine, Mayo Clinic, Jacksonville, FL, USA Abstract: Human epidermal growth factor receptor 2 (HER2 is a tyrosine kinase transmembrane receptor that is overexpressed on the surface of 15%–20% of breast tumors and has been associated with poor prognosis. Consistently improved pathologic response and survival rates have been demonstrated with use of trastuzumab in combination with standard chemotherapy in both early and advanced breast cancer. However, resistance to trastuzumab may pose a major problem in the effective treatment of HER2-positive breast cancer. Dual HER2 blockade, using agents that work in a complimentary fashion to trastuzumab, has more recently been explored to evade resistance in both the preoperative (neoadjuvant and adjuvant settings. Increased effectiveness of dual anti-HER2 agents over single blockade has been recently reported in clinical studies. Pertuzumab in combination with trastuzumab and taxane is currently approved in the metastatic and neoadjuvant treatment of HER2-positive breast cancer. Various biomarkers have also been investigated to identify subsets of patients with HER2-positive tumors who would likely respond best to these targeted therapy combinations. In this article, available trial data regarding efficacy and toxicity of treatment with combination HER2 agents in the neoadjuvant and adjuvant setting have been reviewed, and relevant correlative biomarker data from these trials have been discussed.

    Hepatitis B virus (HBV) vaccination is recommended for all susceptible chronic pre-hemodialysis and hemodialysis patients. This study assessed the immunogenicity of HBV vaccines (adjuvanted and non-adjuvanted) in chronic kidney disease patients vaccinated at the Hospital Clinic of Barcelona (Spain) between January 2007 and July 2012. In addition, the costs for the health system were evaluated accor-ding to the proportion of vaccine responders after receiving either vaccine. Patients receiving 3 doses of hepatitis B adjuvanted vaccine were 3 times more likely to seroconvert than patients immunized with non-adjuvanted vaccines, OR 3.56 (95% CI 1.84-6.85). This resulted in fewer patients requiring a second course of HBV vaccination and fewer outpatient visits, saving more than €9,500 per 100 patients. The higher immunogenicity of the adjuvanted HBV vaccine would counterbalance the lower costs associated with the non-adjuvanted vaccine.

    Background. Immunosuppression is a well-recognised complication of chemotherapy in cancer patients. We assemble the clinical evidence that SQI, an adjuvant drug for lung cancer and gastric cancer which was widely prescribed in China, interventions could increase objective tumour response and regulate immunity in cancer patients undergoing chemotherapy. Methods. We undertook a systemic review of the clinical data from randomised controlled trials up to September 2015 in which a SQI intervention was compared with a control arm in patients undergoing conventional chemotherapy. Revman 5.0 Software was used for the data analysis. Results. 49 randomised controlled trials were included in the systematic review. The meta-analysis results demonstrated that the SQI intervention with conventional chemotherapy exhibited better therapeutic efficacy than the conventional chemotherapy group with a statistically significant higher objective tumour response. Cotreatment with SQI could enhance NK, CD3+, CD4+ level, and CD4+/CD8+ ratio comparing with the conventional chemotherapy group. Conclusions. The conclusions of this review might suggest a high risk of bias due to the low quality and the limitation of cancer types in the included trials. A more reliable conclusion regarding the immunoregulation of SQI could be reached based on more trials of higher quality.

Our study aimed at evaluating the feasibility of breast conversation surgery (BCS after neoadjuvant chemotherapy. Patients and methods Forty five patients had stage IIB (except those with T2N1 disease and stage IIIA were selected to 3 cycles taxane-based neoadjuvant chemotherapy. Patient who had tumours ≤5 cm underwent a tentative BCS while patients who had tumour size >5 cm underwent radical surgery. Negative margin is essential for BCS. Adjuvant chemotherapy and 3-D radiotherapy ± hormonal treatment were given to all patients. Results Thirty four patients had BCS. Response to chemotherapy was the only statistically significant factor which influences the BCS. Incidence of local recurrence was 5.9% for patients who had BCS at a median follow up 24 months. Conclusion Breast conservation is feasible in selected cases of locally advanced, non metastatic cancer breast. We recommend that patients who have tumour size ≤4 cm after chemotherapy are the best candidates for BCS.

    Publicly available microarray data suggests that the expression of FAM83D (Family with sequence similarity 83, member D) is elevated in a wide variety of tumor types, including hepatocellular carcinoma (HCC). However, its role in the pathogenesis of HCC has not been elucidated. Here, we showed that FAM83D was frequently up-regulated in HCC samples. Forced FAM83D expression in HCC cell lines significantly promoted their proliferation and colony formation while FAM83D knockdown resulted in the opposite effects. Mechanistic analyses indicated that FAM83D was able to activate the MEK/ERK signaling pathway and promote the entry into S phase of cell cycle progression. Taken together, these results demonstrate that FAM83D is a novel oncogene in HCC development and may constitute a potential therapeutic target in HCC. - Highlights: • FAM83D is up-regulated in HCC tissues and cell lines. • Ectopic expression of FAM83D promotes HCC cell proliferation and colony formation. • Depletion of FAM83D inhibits HCC cell proliferation and colony formation. • FAM83D activates the MEK/ERK signaling pathway in HCC.

    Aim: To investigate the impact of nonstandard concomitant temozolomide (TMZ) administration in two prospective phase II studies for glioblastoma (GBM). Patients and methods: From October 2000 to June 2008, 104 patients were enrolled in two studies: 25 in RT-TMZ-10.00 and 79 in RT-TMZ-01.04. Adjuvant radiotherapy (RT) was used with a total dose of 59.4 Gy (1.8 Gy/day). Patients received concomitant TMZ (75 mg/m{sup 2}/day) from Monday to Friday during the first and last weeks of RT in the RT-TMZ-10.00 study and from Monday to Friday during all weeks of RT in the RT-TMZ-01.04 trial. Adjuvant TMZ (200 mg/m{sup 2}) was administered for 5 days every 28 days. Results: Median progression-free (PFS) and overall survival (OS) were 9 and 16 months, respectively, with no significant difference between the two groups (p = 0.5 and 0.14, respectively). The 2- and 5-year OS rates were 32 and 3 %, respectively, and similar to those observed with standard treatment regimens. Conclusion: Our data support the hypothesis that adjuvant TMZ is more important than concomitant chemotherapy (CH) and that RT is the more important element of the concomitant treatment schedule.

    Full Text Available Este artigo centra-se no tema assistência a idosos dependentes por doença crônica e degenerativa, e chama a atenção para o papel do cuidador em casa. A recomendação para que os cuidados aos idosos dependentes sejam desenvolvidos no domicílio está ganhando mais força, muitas vezes de maneira incauta por parte dos profissionais de saúde. Delegar à família a função de cuidar necessita de clareza sobre a estrutura familiar, o tipo de cuidado a ser executado, o tempo necessário, as características da doença e o acompanhamento profissional. Em países onde o envelhecimento populacional se deu mais lentamente do que no Brasil, os cuidados e os cuidadores familiares são objeto de políticas e programas de Saúde Pública.

    Purpose: Radiotherapy (RT) and chemotherapy may prolong survival in older patients (age {>=}70 years) with glioblastoma multiforme (GBM), although the survival benefits remain poor. This Phase II multicenter study was designed to evaluate the efficacy and safety of an abbreviated course of RT plus concomitant and adjuvant temozolomide (TMZ) in older patients with GBM. Patients and Methods: Seventy-one eligible patients 70 years of age or older with newly diagnosed GBM and a Karnofsky performance status {>=}60 were treated with a short course of RT (40 Gy in 15 fractions over 3 weeks) plus TMZ at the dosage of 75 mg/m{sup 2} per day followed by 12 cycles of adjuvant TMZ (150-200 mg/m{sup 2} for 5 days during each 28-day cycle). The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival and toxicity. Results: The Median OS was 12.4 months, and the 1-year and 2-year OS rates were 58% and 20%, respectively. The median and 1-year rates of progression-free survival were 6 months and 20%, respectively. All patients completed the planned programme of RT. Grade 3 or 4 adverse events occurred in 16 patients (22%). Grade 3 and 4 neutropenia and/or thrombocytopenia occurred in 10 patients (15%), leading to the interruption of treatment in 6 patients (8%). Nonhematologic Grade 3 toxicity was rare, and included fatigue in 4 patients and cognitive disability in 1 patient. Conclusions: A combination of an abbreviated course of RT plus concomitant and adjuvant TMZ is well tolerated and may prolong survival in elderly patients with GBM. Future randomized studies need to evaluate the efficacy and toxicity of different schedules of RT in association with chemotherapy.

    Lymphangioleiomyomatosis is a rare cause of pneumothorax in women. We present the case of a 48-year-old woman with lymphangioleiomyomatosis, who had never had a pneumothorax prior to commencing chemotherapy for breast cancer. During chemotherapy she developed 3 pneumothoraces and 2 episodes of pneumomediastinum. We suggest that the pneumothoraces were caused by the chemotherapy. To our knowledge, this is the first reported case of chemotherapy triggering pneumothoraces in a woman with lymphangioleiomyomatosis.

  9. The mode of action of immunological adjuvants.

    Adjuvants augment immune responses to antigens and influence the balance between cell-mediated and humoral responses, as well as the isotypes of antibodies formed. New adjuvant formulations include antigen-carrying vehicles and small molecules with immunomodulating activity. Widely used two-phase vehicles comprise liposomes and microfluidized squalene or squalane emulsions. These are believed to target antigens to antigen-presenting cells, including dendritic cells (DC), follicular dendritic cells (FDC) and B-lymphocytes. Activation of complement generates C3d, which binds CR2 (CD21) on FDC and B-lymphocytes, thereby stimulating the proliferation of the latter and the generation of B-memory. Targeting of antigens to DC may favour cell-mediated immunity. Immunomodulating agents induce the production of cytokine cascades. In a primary cascade at injection sites TNF-alpha, GM-CSF and IL-1 are produced. TNF-alpha promotes migration of DC to lymphoid tissues, while GM-CSF and IL-1 accelerate the maturation of DC into efficient antigen-presenting cells for T-lymphocytes. In a secondary cytokine cascade in draining lymph nodes, DC produce IL-12, which induces Th1 responses with the production of IFN-gamma. The cytokines elicit cell-mediated immune responses and the formation of antibodies of protective isotypes, such as IgG2a in the mouse and IgG1 in humans. Antibodies of these isotypes activate complement and collaborate with antibody-dependent effector cells in protective immune responses.

    Cancers of esophagus and stomach are common malignant diseases worldwide, and they are associated with serious morbidity and high mortality rates. When diagnosed at an early stage, gastro-esophageal cancers are potentially curable. Neo-adjuvant or adjuvant therapies using both chemotherapy and radiation therapy have been shown to reduce the risk of local recurrence and distant metastasis. For advanced or metastatic tumors, systemic chemotherapy offers symptomatic palliation and moderate benefits in survival. With recent advances in anti-cancer therapeutics, progress has been made to improve treatment response and life expectancy in patients with advanced gastro-esophageal cancers. Furthermore, the clinical use of molecularly targeted agents in combination with cytotoxic chemotherapeutics is being evaluated in a number of ongoing clinical trials. In this article, we review currently used standard systemic therapies including recently evolving targeted therapies for metastatic gastro-esophageal cancers, as well as the proven role and the regimens that are used as neoadjuvant and adjuvant treatment in localized gastro-esophageal cancers.

    Full Text Available Abstract Background Tuberculosis (TB is increasing in the world and drug-resistant (DR disease beckons new treatments. Methods To evaluate the action of interferon (IFN gamma as immunoadjuvant to chemotherapy on pulmonary DR-TB patients, a pilot, open label clinical trial was carried out in the Cuban reference ward for the management of this disease. The eight subjects existing in the country at the moment received, as in-patients, 1 × 106 IU of recombinant human IFN gamma intramuscularly, daily for one month and then three times per week up to 6 months as adjuvant to the indicated chemotherapy, according to their antibiograms and WHO guidelines. Sputum samples collection for direct smear observation and culture as well as routine clinical and thorax radiography assessments were done monthly. Results Sputum smears and cultures became negative for acid-fast-bacilli before three months of treatment in all patients. Lesion size was reduced at the end of 6 months treatment; the lesions disappeared in one case. Clinical improvement was also evident; body mass index increased in general. Interferon gamma was well tolerated. Few adverse events were registered, mostly mild; fever and arthralgias prevailed. Conclusions These data suggest that IFN gamma is useful and well tolerated as adjunctive therapy in patients with DR-TB. Further controlled clinical trials are encouraged.

    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.

    Full Text Available "nBackground: Although postoperative chemoradiotherapy should be considered for all patients at high risk for recurrence of adenocarcinoma of the stomach, curative surgery occurs in less than 50% of nonmetastatic gastric cancers. A regimen of docetaxel, cisplatin and infusional fluorouracil improves survival of patients with incurable locally-advanced gastric adenocarcinoma. So we assessed the perioperative regimen of docetaxel, cisplatin and infusions 5FU (TCF and postoperative chemoradiotherapy to improve outcomes in patients with potentially resectable gastric adenocarcinoma. "nMethods: Between March 2005 and March 2008, we 100 enrolled patients with stage II to IV (M0 adenocarcinoma of the stomach who had not been treated previously. Treatment consisted of three preoperative and one postoperative cycles of TCF followed by chemoradiotherapy. The primary end point was overall survival. The secondary end points were progression-free survival and toxicity of treatment. "nResults: A total of 100 patients participated, 83 of whom received neoadjuvant and 17 received adjuvant chemotherapy. Seventy-five patients underwent at least D0 gastrectomy. After chemotherapy, tumor stages were significantly lower than before beginning the protocol. Out of 100 patients, 44 had stage IV before chemotherapy versus 15 after the treatment. Three patients showed complete pathologic response. The median survival time was 25 months. "nConclusion: Docetaxel, cisplatin and 5FU combination chemotherapy is an active preoperative treatment in locally advanced gastric cancer. Perioperative chemoradio-therapy should be considered as an option to lengthen patient survival.

    Despite advances in antiemetic therapy, chemotherapy-induced nausea and vomiting (CINV) still poses a significant burden to patients undergoing chemotherapy. Nausea, in particular, is still highly prevalent in this population. Ginger has been traditionally used as a folk remedy for gastrointestinal complaints and has been suggested as a viable adjuvant treatment for nausea and vomiting in the cancer context. Substantial research has revealed ginger to possess properties that could exert multiple beneficial effects on chemotherapy patients who experience nausea and vomiting. Bioactive compounds within the rhizome of ginger, particularly the gingerol and shogaol class of compounds, interact with several pathways that are directly implicated in CINV in addition to pathways that could play secondary roles by exacerbating symptoms. These properties include 5-HT3, substance P, and acetylcholine receptor antagonism; antiinflammatory properties; and modulation of cellular redox signaling, vasopressin release, gastrointestinal motility, and gastric emptying rate. This review outlines these proposed mechanisms by discussing the results of clinical, in vitro, and animal studies both within the chemotherapy context and in other relevant fields. The evidence presented in this review indicates that ginger possesses multiple properties that could be beneficial in reducing CINV.

  19. Hepatic arterial infusion pump chemotherapy for colorectal liver metastases: an old technology in a new era.

    Aggressive treatment of colorectal cancer (crc) liver metastases can yield long-term survival and cure. Unfortunately, most patients present with technically unresectable metastases; conventional therapy in such patients consists of systemic therapy. Despite advances in the effectiveness of systemic therapy in the first-line setting, the tumour response rate and median survival remain low in the second-line setting. The preferential blood supply from the hepatic artery to crc liver metastases allows for excellent regional delivery of chemotherapy. Here, we review efficacy and safety data for hepatic artery infusion (hai) pump chemotherapy in patients with metastatic crc from the 5-fluorouracil era and from the era of modern chemotherapy. In selected patients with liver-only or liver-dominant disease who have progressed on first-line chemotherapy, hai combined with systemic agents is a viable therapeutic option when performed at experienced centres. Furthermore, significantly improved survival has been demonstrated with adjuvant hai therapy after liver resection in the phase iii setting. The complication rates and local toxicities associated with hai pump therapy are infrequent at experienced centres and can be managed with careful follow-up and early intervention. The major obstacles to the wide adoption of hai therapy include technical expertise for pump insertion and maintenance, and for floxuridine dose modification. The creation of formal preceptor-focused education and training in hai therapy for interdisciplinary medical professionals might encourage the creation and expansion of this liver-directed approach.

    Forty-five patients with muscle-invasive bladder cancer treated with intra-arterial doxorubicin chemotherapy plus low-dose radiotherapy between September 1979 and March 1990 were retrospectively studied. Twenty-eight (62%) patients achieved a complete response (CR) and in all of them, a functional bladder could be preserved. The 10-year cause-specific survival rate of patients with CR was 95.5%, but that of patients not achieving a CR was 39%. These results demonstrate that in patients who achieve a CR with this treatment, we may be able to preserve a functional bladder. In a prospective study, we designed a new intra-arterial chemotherapy regimen in order to achieve a higher degree of effectiveness and to preserve a functional bladder. Twenty-three patients were treated with concurrent pirarubicin/cisplatin intra-arterial chemotherapy and radiotherapy after complete transurethral resection. Twenty-one (91%) patients achieved CR. One of these patients had relapse with lung metastases and was treated surgically. Two patients who did not achieve a CR died of cancer, and 21 patients are alive with preservation of functional bladder. For treatment of prostate cancer, we now administer only adjuvant intra-arterial chemotherapy plus irradiation for patients after radical prostatectomy. (author)
