    Pancreatic endocrine tumors (PETs) are characterised by an indolent behaviour in terms of tumor growth. However, most patients display metastasis at diagnosis and no cure is currently available. Since the PI3K/AKT/mTOR axis is deregulated in PETs, the mTOR inhibitor RAD001 represents the first line treatment. Nevertheless, some patients do not respond to treatments and most acquire resistance. Inhibition of mTOR leads to feedback re-activation of PI3K activity, which may promote resistance to RAD001. Thus, PI3K represents a novel potential target for PETs. We tested the impact of three novel PI3K inhibitors (BEZ235, BKM120 and BYL719) on proliferation of PET cells that are responsive (BON-1) or unresponsive (QGP-1) to RAD001. BEZ235 was the most efficient in inhibiting proliferation in PET cells. Furthermore, combined treatment with BEZ235 and RAD001 exhibited synergic effects and was also effective in BON-1 that acquired resistance to RAD001 (BON-1 RR). Analysis of PI3K/AKT/mTOR pathway showed that RAD001 and BEZ235 only partially inhibited mTOR-dependent phosphorylation of 4EBP1. By contrast, combined therapy with the two inhibitors strongly inhibited phosphorylation of 4EBP1, assembly of the translational initiation complex and protein synthesis. Thus, combined treatment with BEZ235 may represent suitable therapy to counteract primary and acquired resistance to RAD001 in PETs.

    Purpose: To determine the safety of the mammalian target of rapamycin inhibitor everolimus (RAD001) administered daily with concurrent radiation and temozolomide in newly diagnosed glioblastoma patients. Methods and Materials: Everolimus was administered daily with concurrent radiation (60 Gy in 30 fractions) and temozolomide (75 mg/m{sup 2} per day). Everolimus was escalated from 2.5 mg/d (dose level 1) to 5 mg/d (dose level 2) to 10 mg/d (dose level 3). Adjuvant temozolomide was delivered at 150 to 200 mg/m{sup 2} on days 1 to 5, every 28 days, for up to 12 cycles, with concurrent everolimus at the previously established daily dose of 10 mg/d. Dose escalation continued if a dose level produced dose-limiting toxicities (DLTs) in fewer than 3 of the first 6 evaluable patients. Results: Between October 28, 2010, and July 2, 2012, the Radiation Therapy Oncology Group 0913 protocol initially registered a total of 35 patients, with 25 patients successfully meeting enrollment criteria receiving the drug and evaluable for toxicity. Everolimus was successfully escalated to the predetermined maximum tolerated dose of 10 mg/d. Two of the first 6 eligible patients had a DLT at each dose level. DLTs included gait disturbance, febrile neutropenia, rash, fatigue, thrombocytopenia, hypoxia, ear pain, headache, and mucositis. Other common toxicities were grade 1 or 2 hypercholesterolemia and hypertriglyceridemia. At the time of analysis, there was 1 death reported, which was attributed to tumor progression. Conclusions: Daily oral everolimus (10 mg) combined with both concurrent radiation and temozolomide followed by adjuvant temozolomide is well tolerated, with an acceptable toxicity profile. A randomized phase 2 clinical trial with mandatory correlative biomarker analysis is currently under way, designed to both determine the efficacy of this regimen and identify molecular determinants of response.

    Mammalian target of rapamycin (mTOR) pathway is activated in malignant melanoma and in situ lesions as opposed to benign nevi. Inhibition of PI3K-Akt-mTOR signaling is implicated in sensitization of melanoma cells to alkylating agents (temozolomide [TMZ]) and inhibition of tumor angiogenesis. We conducted a single-arm phase II multi-institution cooperative group study to assess the antitumor activity and safety profile of the combination of TMZ and the rapamycin derivative everolimus in patients with metastatic unresectable malignant melanoma. Patients received 10 mg/d of RAD001 for 5 of 7 days (ie, 50 mg/wk) and 200 mg/m/d of TMZ for 5 days each cycle. Of the first 39 eligible patients, 17 were PFS-9 successes, for a predetermined threshold of 18/39 patients for a positive trial. Overall, 21 of 48 patients were progression free at 9 weeks, for an event-free survival rate of 44% (95% confidence interval, 29%-59%). The median progression-free survival was 2.4 months and the median overall survival was 8.6 months. Four patients achieved a partial response; the median duration of response was 15.1 months. No complete remissions were observed. Treatment was in general well tolerated with only 1 patient discontinuing therapy due to toxicity (hyperlipidemia). The combination of TMZ and RAD001 was well tolerated but failed to meet/exceed our study threshold for promising clinical activity in patients with metastatic melanoma.

    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.

    Purpose We investigated the effect of the mTOR inhibitor everolimus (RAD001) on human bladder cancer (BC) cells in vitro and in vivo. Experimental Design The effect of RAD001 on the growth of UM-UC-3, UM-UC-6, UM-UC-9, and UM-UC-14 BC cells were assessed by crystal violet and [3H]Thymidine incorporation assays . Flow cytometry cell cycle analyses were performed to measure the apoptotic cell fraction. Protein synthesis was measured using tritium-labeled leucine–incorporation assays. The effects of RAD001 on the mTOR pathway were analyzed by western blotting. To test the effects of RAD001 in vivo, UM-UC-3, UM-UC-6, and UMUC-9 cells were subcutaneously implanted into nude mice. Tumor-bearing mice were treated orally with RAD001 or placebo. Tumors were harvested for immunohistochemical analysis. Results In vitro, RAD001 transiently inhibited BC cell growth in a dose-dependent manner. This effect was augmented by retreatment of cells after 3 days. UM-UC-14 cells were the most sensitive to RAD001, while UM-UC-9 cells were the least sensitive. After retreatment with RAD001, only sensitive cell lines showed G1 phase arrest, with no evidence of apoptosis. RAD001 significantly inhibited the growth of tumors that were subcutaneously implanted in mice. Inhibition of protein synthesis through the S6K and 4E-BP1 pathways appears to be the main mechanism for the RAD001-induced growth inhibition. However, inhibition of angiogenesis was the predominant mechanism of RAD001's effect on UM-UC-9 cells. Conclusions The mTOR inhibitor RAD001 inhibits growth of BC cells in vitro. RAD001 is effective in treating BC tumors in an in vivo nude mouse model despite the heterogeneity of in vitro responses. PMID:21415218

    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.

    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.

The PI3K/AKT/mTOR pathway enhances tumor survival and proliferation through suppressing autophagy, which sustains energy homeostasis by collecting and recycling cellular components under stress conditions. Conversely, inhibitors of the mTOR pathway such as RAD001 induce autophagy, leading to promotion of tumor survival and limited antitumor efficacy. We thus hypothesized that the use of autophagy inhibitor in combination with mTOR inhibition improves the cytotoxicity of mTOR inhibitors in bladder cancer.Materials and methods: The cytotoxicity of RT4, 5637, HT1376, and T24 human bladder cancer cells treated with RAD001 alone or combined with autophagy inhibitors (3-methyladenine (3-MA, bafilomycin A1 (Baf A1, chloroquine, or hydroxychloroquine was assessed using the WST-8 cell viability kit. The autophagy status in cells was analyzed by the detection of microtubule-associated light chain 3 form II (LC3-II, using immunofluorescent staining and Western blot. Acidic vesicular organelle (AVO formation in treated cells was determined by acridine orange vital staining. Inhibition of mTOR pathway by RAD001 was monitored by using a homemade quantitative polymerase chain reaction gene array, while phospho-mTOR was detected using Western blot. Induced apoptosis was determined by measurement of caspase 3/7 activity and DNA fragmentation in cells after

    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.

  13. RAD001 enhances the potency of BEZ235 to inhibit mTOR signaling and tumor growth.

    Directory of Open Access Journals (Sweden)

    Beat Nyfeler

    Full Text Available The mammalian target of rapamycin (mTOR is regulated by oncogenic growth factor signals and plays a pivotal role in controlling cellular metabolism, growth and survival. Everolimus (RAD001 is an allosteric mTOR inhibitor that has shown marked efficacy in certain cancers but is unable to completely inhibit mTOR activity. ATP-competitive mTOR inhibitors such as NVP-BEZ235 can block rapamycin-insensitive mTOR readouts and have entered clinical development as anti-cancer agents. Here, we show the degree to which RAD001 and BEZ235 can be synergistically combined to inhibit mTOR pathway activation, cell proliferation and tumor growth, both in vitro and in vivo. RAD001 and BEZ235 synergized in cancer lines representing different lineages and genetic backgrounds. Strong synergy is seen in neuronal, renal, breast, lung, and haematopoietic cancer cells harboring abnormalities in PTEN, VHL, LKB1, Her2, or KRAS. Critically, in the presence of RAD001, the mTOR-4EBP1 pathway and tumorigenesis can be fully inhibited using lower doses of BEZ235. This is relevant since RAD001 is relatively well tolerated in patients while the toxicity profiles of ATP-competitive mTOR inhibitors are currently unknown.

    Sequential application of target drugs is standard procedure after renal cell carcinoma (RCC) patients develop resistance. To optimize the sequence, antitumour effects of the mTOR inhibitor RAD001 or the tyrosine kinase inhibitor (TKI) sorafenib on RCC cells with acquired resistance to the TKI sunitinib was evaluated. RCC cells were exposed to 1 μM sunitinib for 24 hrs (as control) and for 8 weeks (to induce resistance) and then switched to RAD001 (5 nM) or sorafenib (5 μM) for a further 8 weeks. Tumour cell growth, cell cycle progression, cell cycle regulating proteins and intracellular signalling were then investigated. Short-term application of sunitinib (24 hrs) induced cell growth blockade with accumulation in the G2/M phase. RCC cells became resistant to sunitinib after 8 weeks, demonstrated by accelerated cell growth along with enhanced cdk1, cdk2, loss of p27, activation of Akt, Rictor and Raptor. Switching to sorafenib only slightly reduced growth of the sunitinib resistant RCC cells and molecular analysis indicated distinct cross-resistance. In contrast, full response was achieved when the cancer cells were treated with RAD001. p19 and p27 strongly increased, phosphorylated Akt, Rictor and Raptor decreased and the tumour cells accumulated in G0/G1. It is concluded that an mTOR-inhibitor for second-line therapy could be the strategy of choice after first-line sunitinib failure.

    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.

    Despite the decreasing frequency of gastric cancer in most Western countries prognosis could not be improved by surgery alone in the past. Advanced tumor stage due to late diagnosis is one of the reasons for this observation. Contrary to breast and colorectal cancer, postoperative chemotherapy failed to improve prognosis in gastric cancer. Small number of patients in Western studies, insufficient surgical procedures and the high frequency of locoregional relapse may be attributed for this observation. Intraperitoneal, adjuvant chemotherapy showed a positive impact on survival in Asian studies only, but was also used successfully as a part of a multimodality approach in Western phase II trials. Since neoadjuvant therapy proved to create downstaging of tumor size in some patients with advanced gastric cancer some working groups tried to influence prognosis of potentially resectable tumors by preoperative chemotherapy, surgical resection and postoperative, adjuvant therapy in the recent past. However, the efficacy of this therapeutic approach has to be reconfirmed in a controlled, phase III fashion.

    To investigate the effect of spa adjuvant therapy on diabetic lower extremity arterial disease (LEAD). 128 patients with type II diabetes were separated into three groups according to the degree of lower extremity vascular stenosis. Patients within each group were then randomly divided to receive no treatment (control) or spa adjuvant therapy (treatment). Clinical symptoms, blood pressure and hemodynamic analyses were compared between control and treatment groups by Chi square or t-test. After adjuvant therapy with spa, patients' pain, numbness, and cold sensation were significantly improved compared with control groups (PSpa adjuvant therapy also significantly increased the dorsalis pedis pulse and systolic peak velocity ratio of patients with mild lower extremity vascular stenosis compared with control groups (P0.05). Both in the spa and control groups, there were no significant differences before and after medication for fasting, 2-h postprandial blood glucose and glycosylated hemoglobin (HbA1C) analyses (P>0.05). Spa adjuvant therapy can significantly alleviate lower extremity pain, numbness, and cold sensory symptoms in diabetic LEAD patients with stenosis. Moreover, in LEAD patients with mild stenosis, spa adjuvant therapy also improves the dorsalis pedis pulse and systolic peak velocity ratio, suggesting a potential role for spa therapy as an early intervention strategy to treat the initial stages of disease.

    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.

    Deregulation of the phosphatidylinositol-3-kinase (PI3K)/Akt signalling pathway is common in breast cancer and is frequently associated with resistance to both traditional chemotherapy and targeted drugs. There is a growing body of evidence indicating that a small subpopulation of self-renewing cells, the so called cancer stem cells (CSC), are responsible for the growth of drug resistant secondary tumors. As many CSCs have upregulated the PI3K/Akt signalling pathway, preclinical and clinical studies are addressing the inhibition of this axis to target drug resistance. We evaluated the susceptibility of breast CSCs to NVP-BKM120 (BKM120), a new generation of PI3K-specific inhibitor, when used individually or in combination with trastuzumab or RAD001 both in vitro and in vivo. For this, a stem-like cell population (SC) was enriched from breast cancer cell lines after mammosphere cultures. We demonstrated that BKM120 inhibits growth, generation of drug-resistant derivatives and SC formation in a panel of four breast cancer cell lines: MCF-7, MDA-MB-231, SK-BR-3 and CAL51. Importantly, BKM120 inhibits the PI3K/Akt signalling pathway in SCs from these cell lines. When BKM120 was used in combination with trastuzumab, a targeted therapy to treat HER2-positive breast cancer, we found synergistic cell growth inhibition, generation of drug resistant cells as well as SC formation from SK-BR-3 cells. Importantly, SK-BR-3 xenograft-derived tumors showed marginal growth when the drug combination was used. We also found a similar synergistic anticancer effect of BKM120 in combination with RAD001, an mTOR inhibitor, when treating triple-negative breast cancer cells in vitro and in both MDA-MB-231 and CAL51- mouse xenografts. Moreover, mouse data indicate that these drug combinations are well tolerated and provide the proof-of-concept and rationale to initiate clinical trials in both HER2-positive and triple-negative breast cancer.

    To determine how many breast cancer patients who initiated adjuvant endocrine therapy discontinued early and to evaluate adherence in patients who persisted with therapy. Secondary objectives were to explore possible trends to see if certain factors may correlate to early discontinuation of therapy. A retrospective review of charts and pharmacy dispensing records was conducted, including patients who initiated adjuvant endocrine therapy for breast cancer at the Cross Cancer Institute from 1 January to 31 December, 2006. Out of 346 patients, 81 (22%) discontinued therapy within 2 years. Adherence rates calculated for the 265 patients who remained on therapy beyond 2 years showed that 247 (93%) of these patients had 80% or better adherence. Patients who did not undergo chemotherapy and patients with Cross Cancer Institute follow-up times of less than 1 year were significantly more likely to discontinue therapy early. The majority of patients who were prescribed adjuvant endocrine therapy for breast cancer at the Cross Cancer Institute remained on therapy for at least 2 years and were adherent. Longer follow-up by Cross Cancer Institute practitioners may help decrease discontinuation rates.

    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.

    The objective of this study is to evaluate the therapeutic efficacy of melatonin as an adjuvant therapy in treating neonatal sepsis. A prospective clinical trial study was conducted on 50 infants with neonatal sepsis diagnosed on the basis of both clinical and laboratory criteria. Enrolled infants were divided into two groups. Intervention group (n = 25) received melatonin and antibiotics, while the control group (n = 25) was treated with antibiotics only. Melatonin was administered as a single oral dose of 20 mg and antibiotics were administered according to a standard protocol. Both groups were compared using a predefined sepsis score utilizing both clinical and laboratory parameters. There was no significant difference in sepsis score between both groups before starting melatonin (p-value = 0.99), while there was significant difference in sepsis score between groups after 24 hours, 48 hours and 72 hours of starting melatonin with (p-value = 0.008, 0.006 and 0.002, respectively). There was significant improvement sepsis score in both groups with more improvement of sepsis score in the intervention group. Administration of melatonin as an adjuvant therapy in the treatment of neonatal sepsis is associated with improvement of clinical and laboratory outcomes.

    BACKGROUND: Justification for adjuvant radio-iodine (I-131) therapy in differentiated thyroid cancer (DTC) is purely based on retrospective data. This is true for ablative therapy and even more so for high-dosage adjuvant schedules. Randomized trials on the latter application are considered impossib

    IMPORTANCE There is an immediate need to develop local intraoperative adjuvant treatment strategies to improve outcomes in patients with cancer who undergo head and neck surgery. OBJECTIVES To determine the safety of photodynamic therapy with 2-(1-hexyloxyethyl)-2-devinyl pyropheophorbide-a (HPPH) in combination with surgery in patients with head and neck squamous cell carcinoma. DESIGN, SETTING, AND PARTICIPANTS Nonrandomized, single-arm, single-site, phase 1 study at a comprehensive cancer center among 16 adult patients (median age, 65 years) with biopsy-proved primary or recurrent resectable head and neck squamous cell carcinoma. INTERVENTIONS Intravenous injection of HPPH (4.0 mg/m2), followed by activation with 665-nm laser light in the surgical bed immediately after tumor resection. MAIN OUTCOMES AND MEASURES Adverse events and highest laser light dose. RESULTS Fifteen patients received the full course of treatment, and 1 patient received HPPH without intraoperative laser light because of an unrelated myocardial infarction. Disease sites included larynx (7 patients), oral cavity (6 patients), skin (1 patient), ear canal (1 patient), and oropharynx (1 patient, who received HPPH only). The most frequent adverse events related to photodynamic therapy were mild to moderate edema (9 patients) and pain (3 patients). One patient developed a grade 3 fistula after salvage laryngectomy, and another patient developed a grade 3 wound infection and mandibular fracture. Phototoxicity reactions included 1 moderate photophobia and 2 mild to moderate skin burns (2 due to operating room spotlights and 1 due to the pulse oximeter). The highest laser light dose was 75 J/cm2. CONCLUSIONS AND RELEVANCE The adjuvant use of HPPH-photodynamic therapy and surgery for head and neck squamous cell carcinoma seems safe and deserves further study. PMID:23868427

    The mortality rate of severe sepsis and septic shock remains still high. Within the last years a better knowledge of its physiopathology and the implementation of a group of measures addressed to a fast identification and early treatment of the septic patients have proved to reduce mortality rate. Likewise, it continues being investigated in modulating the inflammatory response and limiting the harmful action of the bacterial products on the immune system. As a result of this research some endotoxin adsorber devices have been designed to control one of the most important targets that start the inflammatory cascade when gram negative microorganisms are involved.The usefulness that these endotoxin removal devices might have as adjuvant treatment in the Septic Syndrome and its applicability are reviewed in this paper. Likewise a profile of patient that might be to the benefit of this therapy is suggested according to the current knowledge.

    Background Inhibition of mTOR with everolimus may result improve efficacy of taxanes. Everolimus and docetaxel are both metabolized by CYP3A4, which could result in a pharmacokinetic (PK) interaction. Patients and Methods 15 patients with metastatic breast cancer were treated with docetaxel (doses of 40-75 mg/m2 IV on day 1 of a 21 day cycle) in combination with everolimus (doses ranging from 20-50 mg po on days 1 and 8 of a 21 day cycle) in a phase I trial using the continuous reassessment method (CRM) to determine maximum tolerated dose (MTD). The first two patients developed DLT (neutropenic infection), prompting a mandatory dose reduction and PK evaluation of both everolimus and docetaxel for patients enrolled in subsequent dosing cohorts. Results 15 patients were treated. Dose limiting toxicity included grade 3 mucositis (n=1), prolonged grade 4 neutropenia (n=1), and grade 3 infection/febrile neutropenia (n=3). Day 8 of everolimus was commonly held for neutropenia despite a dose reduction in docetaxel to 40mg/m2. Eleven patients underwent complete PK evaluation for everolimus and 9 patients underwent complete PK evaluation for both everolimus and docetaxel. Widely variable changes in clearance were seen for both drugs and the study was terminated due to lack of efficacy and concerns regarding toxicity seen with the combination. Conclusion Weekly everolimus in combination with Q 3-week docetaxel was associated with excessive neutropenia and variable clearance of both drugs making combination therapy unpredictable, even at low doses of both drugs.

    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.

    Many patients with breast cancer are treated for other conditions and experience polypharmacy with multiple concurrent medications. Our aim was to evaluate polypharmacy in relation to adherence to adjuvant endocrine therapy (AET) in breast cancer. We conducted a retrospective cohort study of women with incident, invasive breast cancer initiating AET (tamoxifen, letrozole, anastrozole, exemestane) between 2009 and 2013 in the Truven Health MarketScan Database. Polypharmacy and pill burden were measured for commonly used concurrent medications, including lipid-lowering drugs, antihypertensives, oral diabetes medications, insulin analogs, antidepressants, anxiolytics/antipsychotics, and opioid-containing analgesics. Polypharmacy was defined as frequent use (three or more dispensings) of a given medication class and by pill burden (total dispensings). Medication possession ratios (MPR) were estimated for subsequent 12-month intervals. Multivariable generalized estimating equation models were used to calculate odds ratios (ORs) and robust 95% CIs for associations with AET adherence (MPR ≥ 0.80). Among 40,009 women, 74% were adherent in year +1 and continued to have high mean adherence (MPR = 0.79) among those continuing AET through year +3. Increasing polypharmacy ( P adherence, but effects differed by medication class. Frequent use of lipid-lowering drugs (OR, 1.42; 95% CI, 1.36 to 1.49) and antihypertensives (OR, 1.15; 95% CI, 1.10 to 1.20) were associated with higher odds of adherence; frequent use of opioid-containing analgesics (OR, 0.80; 95% CI, 0.77 to 0.83), anxiolytics/antipsychotics (OR, 0.95; 95% CI, 0.91 to 0.99), antidepressants (OR, 0.85; 95% CI, 0.82 to 0.89), and insulin therapy (OR, 0.82; 95% CI, 0.72 to 0.95) were associated with lower odds of adherence. Associations between polypharmacy and adherence in breast cancer may be better characterized by understanding specific classes of medications used concurrently. Comprehensive medication therapy

    The use of adjuvant endocrine therapy in the treatment of hormone receptor-positive, early breast cancer has become important in both pre- and postmenopausal women. Tamoxifen has been the principal adjuvant hormonal therapy in pre- and postmenopausal women with hormone receptor-positive breast cancer for nearly 20 years. Recent data in premenopausal women suggest benefit from ovarian ablation with or without tamoxifen. Early results from the 'Arimidex', Tamoxifen, Alone or in Combination (ATAC) trial have demonstrated that the third-generation, selective aromatase inhibitor (AI) anastrozole ('Arimidex') is a suitable alternative adjuvant therapy for postmenopausal women with hormone receptor-positive disease. After recurrence or relapse on adjuvant endocrine therapy, responses to the sequential use of additional endocrine agents are common. The increase in the number of options now available for adjuvant therapy will have important implications for the selection of the optimal sequence of endocrine agents in the treatment of recurrent breast cancer. Menopausal status is an important factor in determining the endocrine therapy that a patient receives. For premenopausal women, tamoxifen and/or a luteinizing hormone-releasing hormone agonist such as goserelin ('Zoladex') are both options for adjuvant endocrine treatment. After progression on adjuvant and first-line tamoxifen, ovarian ablation is an appropriate second-line therapy. For premenopausal women who have undergone ovarian ablation, the use of third-line therapy with an AI becomes possible. For postmenopausal women, a wide choice of endocrine treatment options is available and an optimal sequence has yet to be determined. Options for first-line therapy of metastatic disease include an AI for women who have received adjuvant tamoxifen or tamoxifen for patients who have received adjuvant anastrozole. In addition, data suggest that fulvestrant ('Faslodex'), a novel estrogen receptor (ER) antagonist that

    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.

    Appalachia is a largely rural, mountainous, poor and underserved region of the United States. Adherence to adjuvant endocrine therapy among Appalachian women with breast cancer is suboptimal. To explore small-area geographic variations and clustering patterns of breast cancer patient adherence to adjuvant endocrine therapy and associated factors in Appalachia. In this retrospective study, we analyzed Medicare claims data linked with cancer registries from four Appalachian states (PA, OH, KY, and NC) in 2006-2008. We included adult women who were diagnosed with stage I-III, hormone-receptor positive, primary breast cancer and who newly started adjuvant endocrine therapy after the primary treatment for breast cancer. Hot spot analysis was conducted to explore geographic variations in adjuvant endocrine therapy adherence. Geographically weighted logistic regression (GWLR) was used to examine whether the impacts of factors associated with adherence varied across the region. Breast cancer patients living in PA and OH showed higher adherence to adjuvant endocrine therapy than those living in KY and NC. We identified clusters of high adherence in most of PA but poor adherence in Erie County, PA and in Buncombe, Transylvania, Henderson, and Polk Counties, NC. Adherence to adjuvant endocrine therapy was significantly associated with the Health Professional Shortage Area designation, catastrophic coverage, dual-eligibility status of Medicaid and Medicare, adjuvant endocrine therapy drug class, and side effects. And among these factors, the impacts of dual-eligibility status and the use of pain medications to treat side effects on adherence were more pronounced in KY and NC than in PA. There were significant geographic disparities in adherence to adjuvant endocrine therapy in the Appalachian counties in PA, OH, KY, and NC. This study explored these geographic areas with poor adherence as well as geographically varying effects of predictors on adherence; our results may

    Activation of phosphatidylinositol-3-kinase (PI3K)-AKT and Kirsten rat sarcoma viral oncogene homologue (KRAS) can induce cellular immortalization, proliferation, and resistance to anticancer therapeutics such as epidermal growth factor receptor inhibitors or chemotherapy. This study assessed the consequences of inhibiting these two pathways in tumor cells with activation of KRAS, PI3K-AKT, or both. We investigated whether the combination of a novel RAF/vascular endothelial growth factor receptor inhibitor, RAF265, with a mammalian target of rapamycin (mTOR) inhibitor, RAD001 (everolimus), could lead to enhanced antitumoral effects in vitro and in vivo. To address this question, we used cell lines with different status regarding KRAS, PIK3CA, and BRAF mutations, using immunoblotting to evaluate the inhibitors, and MTT and clonogenic assays for effects on cell viability and proliferation. Subcutaneous xenografts were used to assess the activity of the combination in vivo. RAD001 inhibited mTOR downstream signaling in all cell lines, whereas RAF265 inhibited RAF downstream signaling only in BRAF mutant cells. In vitro, addition of RAF265 to RAD001 led to decreased AKT, S6, and Eukaryotic translation initiation factor 4E binding protein 1 phosphorylation in HCT116 cells. In vitro and in vivo, RAD001 addition enhanced the antitumoral effect of RAF265 in HCT116 and H460 cells (both KRAS mut, PIK3CA mut); in contrast, the combination of RAF265 and RAD001 yielded no additional activity in A549 and MDAMB231 cells. The combination of RAF and mTOR inhibitors is effective for enhancing antitumoral effects in cells with deregulation of both RAS-RAF and PI3K, possibly through the cross-inhibition of 4E binding protein 1 and S6 protein.

    The purpose of the present review was to determine whether the use of postoperative adjuvant systemic therapy in patients with completely resected non-small-cell lung cancer (NSCLC) improves survival. Cancer Care Ontario's Program in Evidence-Based Care reviewed the evidence to update previously published recommendations for patients with completely resected NSCLC. Relevant studies were identified from a systematic MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews search of studies published from 2010 to 2016. All phase III randomized controlled trials (RCTs) and relevant systematic reviews were included. Data on overall survival (OS), disease-free survival, adverse events, and quality of life were extracted from each of the studies. Two relevant systematic reviews, 13 RCTs, and a series of pooled analyses by Lung Adjuvant Cisplatin Evaluation-Biomarker were included in the present review. Adjuvant chemotherapy statistically significantly improved OS for resected stage II-IIIA NSCLC and is recommended. For patients with stage IB NSCLC, no significant improvement was seen in OS; however, the results from subgroup analyses indicate that it would be reasonable to consider adjuvant chemotherapy for patients with larger tumors (≥ 4 cm). The present data do not support the use of adjuvant novel therapies (ie, epidermal growth factor receptor tyrosine kinase inhibitor, bevacizumab, and immunotherapy) either as an addition to, or instead of, cytotoxic chemotherapy. No predictive biomarkers are available to select patients more likely to benefit from adjuvant chemotherapy. Cytotoxic chemotherapy remains the standard of care as adjuvant therapy for patients with resected stage II-IIIA NSCLC. Additional clinical trials are needed to evaluate targeted agents in molecularly defined subgroups before these agents can be recommended in the adjuvant setting. Copyright © 2016 Elsevier Inc.

    Semiparasitic plants, mistletoes, distributed in Europe and East-Asia mainly, China, Korea and Japan have long been recognised as therapeutic herbs. Since the 1920s, extracts from European mistletoe (Viscum album L) have been popular in Europe as an unconventional cancer treatment. These extracts have been used in adjuvant cancer therapy because their immunostimulatory, cytostatic/cytotoxic and DNA stabilising activities. The main biological activities are addressed to sugar binding proteins, the Mistletoe Lectins, and to micro proteins named viscotoxins. The mistletoe lectins are members of the family of toxic lectins and recognize sugars and glycoconjugates containing galactose and/or N-acetyl-galactosamine groups. In vitro and in vivo assays confLrm that the mistletoe lectins, isolated from the plant and compared with recombinant forms, play an important role as biologically active principles in mistletoe extracts. Limited experimental evidence indicates that other components like glycosides, polysaccharides, amines etc, may also have anticancer activity. Under discussion in Europe is the principal question of using holo plant extracts or single component lectin preparations: wild type iectins or recombinant ones in cancer therapy. Finally problems of preparation, characterization and standardization of commercial mistletoe preparations and evaluation of biological activities are discussed.%槲寄生属半寄生类植物,主要分布于欧洲及东亚,中国、韩国和日本很早以前就将其作为治疗用药.自上世纪二十年代,欧洲槲寄生提取物因具有免疫调节、抑制细胞生长/细胞毒素和稳定DNA,~性的作用,在欧洲被广泛应用于癌症的辅助治疗.对于槲寄生,其主要生物活性是糖粘合蛋白,槲寄生外源凝集素类和名为粘毒素的微蛋白.槲寄生外源凝集素类是毒性植物血凝素,糖和复合糖类(包括半乳糖和/或N-乙酰半乳糖胺)家族中的成员.活体内、外实验证实,

    Adherence to oral endocrine therapy in adjuvant breast cancer settings is a substantial clinical problem. To provide current perspective on adherence to oral endocrine therapies, a comprehensive literature review was conducted. In adjuvant trials, endocrine therapy adherence is relatively high with greater adherence for aromatase inhibitors compared with tamoxifen. In contrast, adherence to adjuvant therapy in clinical practice is relatively poor, with only about 50% of women successfully completing 5-year therapy. Importantly, good adherence (>80% use) has been associated with lower recurrence risk. Endocrine therapy adherence in primary breast cancer prevention trials parallels that seen in adjuvant trials. Factors associated with nonadherence include low recurrence risk perception, side effects, age extremes, medication cost, suboptimal patient-physician communication, and lack of social support. Few prospective studies have evaluated interventions designed to improve adherence. Interventions currently proposed reflect inferences from clinical trial procedures in which clinical contacts are commonly greater than in usual practice settings. In conclusion, for optimal breast cancer outcome, adherence to endocrine therapy must improve. Although general recommendations likely to improve adherence can be made based on clinical trial results and preliminary prospective trial findings, research specifically targeting this issue is needed to establish effective intervention strategies.

    Adjuvant hormonal therapy significantly improves long-term survival of breast cancer patients with hormone receptor-positive disease. Despite the proven clinical efficacy of tamoxifen and aromatase inhibitors, many breast cancer survivors either fail to take the correct dosage at the prescribed frequency (adherence) or discontinue therapy (persistence). This systematic review aims to: (1) determine the prevalence of adherence and persistence to adjuvant hormonal therapy among breast cancer survivors in clinical practice, and (2) identify correlates of adherence and persistence. We searched Medline, PubMed, PsycINFO, and CINAHL for studies that measured rates and/or correlates of adherence and/or persistence to adjuvant hormonal therapy. Studies were reviewed in a multi-step process: (1) the lead author screened titles and abstracts of all potentially eligible studies; (2) each coauthor reviewed a random 5 % sample of abstracts; and (3) two sets of coauthors each reviewed half of all "maybe" abstracts. Any disagreements were discussed until consensus was reached. Twenty-nine studies met inclusion criteria. Prevalence of adherence ranged from 41 to 72 % and discontinuation (i.e., nonpersistence) ranged from 31 to 73 %, measured at the end of 5 years of treatment. Extremes of age (older or younger), increasing out-of-pocket costs, follow-up care with a general practitioner (vs. oncologist), higher CYP2D6 activity, switching from one form of therapy to another, and treatment side effects were negatively associated with adherence and/or persistence. Taking more medications at baseline, referral to an oncologist, and earlier year at diagnosis were positively associated with adherence and/or persistence. Adherence and persistence to adjuvant hormonal therapy among breast cancer survivors is suboptimal. Many of the correlates of adherence and persistence studied to date are not modifiable. Our review reveals a critical need for further research on modifiable factors

    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.

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

    Hormone receptor (HR) positive breast cancers represent the vast majority of breast cancers. Adjuvant and/or neoadjuvant endocrine therapy is highly effective and appropriate for nearly all women with HR positive tumors. Adjuvant tamoxifen (TAM) is a major endocrine treatment option, which has been found to be effective in both premenopausal and postmenopausal patients. Considerable evidence has been accrued of a benefit for ovarian ablation or suppression (OA/S) in premenopausal patients, for aromatase inhibitors (AIS) in postmenopausal patients, for the longer duration of adjuvant endocrine therapy and for the clinical utility of neoadjuvant endocrine therapy. Clinical practice guidelines should keep changing with developing evidence-based practice guidelines pertaining to breast cancer care. The present publication conducted a comprehensive systematic review of the literature addressing the use of endocrine therapy as adjuvant or neoadjuvant therapy for HR positive breast cancer, focusing on selecting the best agents for both premenopausal and postmenopausal patients, as well as the optimal duration of such treatment.

    Tubular carcinoma of the breast is an uncommon and usually small tumour, and is thought to have a favourable prognosis. The present study examined the long-term prognosis of patients with tubular breast carcinoma and the roles of axillary dissection and adjuvant therapy. Eighty-six tubular cases were identified from a large worldwide database of 9520 breast carcinoma patients entered into randomized adjuvant therapy trials run by the International Breast Cancer Study Group from 1978 to 1999. These patients were followed for a median of 12 years. Forty-two (49%) cases were node-positive, of which 33 (79%) had 1-3 nodes involved. Ten (32%) of the 31 smaller tumours (survival (P = 0.006) and survival (P survival was similar for node-positive and node-negative tubular carcinoma. Overall, 71 patients (83%) received some form of adjuvant systemic therapy. Of the 86 cases, 43 (50%) received more than one course of chemotherapy. There was an 85% decrease in the risk of death for patients who received more than one course of chemotherapy compared to those who did not (hazard ratio 0.15, 95% confidence interval (CI): 0.03-0.82; P = 0.03). Compared to other histological types of breast cancer, tubular carcinoma has a better long-term prognosis. Adjuvant chemotherapy may further improve prognosis and involvement of axillary nodes may not be an indicator for early death due to breast carcinoma.

    To examine the management and outcomes of patients with stage I seminoma and to relate these to overall treatment burden. A total of 764 patients with stage I seminoma underwent surveillance or adjuvant radiation therapy (RT) at a single institution. First relapse on surveillance was managed with RT alone, or with combination chemotherapy (ChT) for more extensive recurrence. Second relapse was managed with ChT. Relapse after adjuvant RT was treated with ChT. The treatment burden was measured, according to the specific treatment undertaken after orchiectomy, by defining treatment episodes as follows: surgery - one episode; one course of RT - one episode; one course of ChT - one episode. In all, 484 patients underwent surveillance and 280 received adjuvant RT. The 5- and 10-year overall survival rates were 98.6 and 97.7% for surveillance, and 97.2 and 91.4% for adjuvant RT. A total of 72 (15%) patients in the surveillance group relapsed; treatment for relapse was RT (n = 56), ChT (n = 15) and surgery (n = 1). Second relapse occurred in six patients; these patients were treated with ChT. Of the patients in the adjuvant RT group, 14 (5%) relapsed: salvage treatment was 10 - ChT (n = 10) surgery (n = 1) and further RT (n = 3). The overall treatment burden represented by number of treatment episodes per patient was 0.16 in the surveillance group and 1.05 in the adjuvant RT group. Surveillance reduces the overall treatment burden in patients with stage I seminoma and is the preferred management option. The selective use of RT at first relapse for patients on surveillance leads to a similar requirement for subsequent ChT to that for patients on adjuvant RT. © 2013 The Authors.

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

    The aim of this review was to examine the toxicity profile of adjuvant interferon (IFN) alfa-2b in melanoma patients from a nursing perspective and to summarize practical information to guide the effective management of common IFN toxicities to improve patient comfort. This is a narrative summary of both research and review articles identified by searching PubMed, National Cancer Institute, and American Cancer Society websites. It also assesses recognized guidelines on the management of adjuvant IFN toxicity relevant to nurses who are caring for patients receiving adjuvant IFN therapy. Adjuvant high-dose IFN alfa-2b (HDI) as compared with observation significantly prolongs relapse-free survival in patients with melanoma at high risk for recurrence after surgical resection; however, treatment compliance and patient quality of life can be compromised by its toxicity profile. HDI toxicities affect a number of organ systems and the majority of patients will experience some side effects. Common toxicities such as flu-like symptoms, fatigue, anorexia, neuropsychiatric symptoms, and laboratory abnormalities are discussed, along with both pharmacological and nonpharmacological management strategies. The considerable side effects of HDI can be managed using established strategies. Oncology nurses play a significant role in the management of patients with melanoma receiving adjuvant HDI, and their prompt recognition of side effects, together with an understanding of effective pharmacological and nonpharmacological interventions, will improve patient comfort; this has the potential to positively influence treatment adherence and completion of the recommended treatment course.

    Luminal A breast cancer has a much better prognosis than other subtypes, with a low risk of local or regional recurrence. However, there is controversy around under- versus overtreatment with regard to adjuvant treatment of node-positive, luminal A breast cancer. The purpose of this study was to identify whether adjuvant systemic chemotherapy has any benefit in node-positive, luminal A breast cancer and to evaluate feasibility of endocrine therapy without chemotherapy in this group.This was a retrospective study of 11,025 patients who were surgically treated for invasive breast cancer at Samsung Medical Center between January 2004 and December 2013. Luminal A subtype was defined as ER+, HER2-, and Ki-67 < 14%. We compared AC based (AC: doxorubicin or epirubicin, plus cyclophosphamide) adjuvant chemotherapy versus endocrine therapy without chemotherapy in patients with node-positive, luminal A breast cancer.We performed 1: n matching, with a maximum n of 8 on endocrine therapy group (n = 50) to chemotherapy group (n = 642). The median age of the patients in each group at the time of surgery was 58.3 ± 9.5 years in the chemotherapy group and 58.7 ± 11.7 in the endocrine therapy only group. The median follow-up time was 51.9 months (range, 1-125 months). In multivariable analysis, omission of adjuvant chemotherapy in luminal A cancer had no influence on OS and DFS. Axillary lymph node metastasis and progesterone receptor (PR) status were significantly different between the endocrine therapy alone group and the chemotherapy group in terms of OS. Nuclear grade, PR status, and adjuvant radiotherapy were significantly different between the endocrine therapy alone group and the chemotherapy group with regard to DFS. In survival analysis, there were no differences in OS (P = .137) and DFS (P = .225) between the 2 groups.Adjuvant chemotherapy could provide little benefit to postmenopausal patients with luminal A, node-positive breast cancer, and

    For patients with hormone receptor positive breast cancer, survivorship entails prolonged self-management of adjuvant treatment in the form of daily hormone therapy. Although sustained daily adherence across the 5-year course of therapy is associated with improved recurrence-free survival outcomes, adherence is suboptimal and many women discontinue hormone therapy prematurely. Factors associated with breast cancer survivors' nonadherence and nonpersistence are not comprehensively understood. Furthermore, psychosocial variables have only received limited research attention, despite their documented relationships with adherence in other chronic illness populations. A systematic literature review identified 14 studies that analyzed relationships between psychosocial factors and breast cancer survivors' adherence and/or persistence with adjuvant hormone therapy. Although identified relationships were complex and at times inconsistent, salient conclusions emerged. Interpersonal factors, in the form of positive social support and patient-centered interactions with medical providers, as well as intrapersonal factors, such as anxiety and beliefs about the relative benefits of medication use, were reliably associated with better adherence and persistence. Depression did not demonstrate the negative impact on adherence that has been observed in other medical populations. No relationships between quality of life and adherence were identified. Adjuvant hormone therapy appears to be a unique context for medication adherence, which warrants further attention and more rigorous analysis in future research. Individual patients' psychosocial characteristics and health care preferences should be considered when striving to optimize medication adherence.

    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.

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

    2009-01-01

    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.

  18. Thymoquinone as a Potential Adjuvant Therapy for Cancer Treatment: Evidence from Preclinical Studies

    2017-06-01

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

    The solitary fibrous tumor of central nervous system is rare. Herein, a case of solitary fibrous tumor arising from sellar region is described. A 60-year-old man underwent subtotal excision of the tumor because of extensive infiltration of optical and vascular structures. In view of the presence of residual tumor, he was treated with adjuvant radiation therapy. After a follow-up period of 1 year, there was no progression of the lesion evident on magnetic resonance imaging of the brain. Solitary fibrous tumor should be considered as one of the differential diagnosis of a mass lesion arising in sellar region. Immunohistochemistry with CD34 is valuable for discerning the diagnosis. Complete surgery should be the goal of treatment and adjuvant radiation therapy may be considered for residual or recurrent disease. PMID:27695561

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

    To design a risk summation to select patients for adjuvant radiation therapy after prostatectomy. A retrospective study was conducted on 629 patients with localised prostate cancer (pN0-pNx) who were treated with prostatectomy and with a prostate-specific antigen (PSA) value 0.4ng/mL. A multivariate Cox regression analysis was performed. A score (0-2) was assigned according to the hazard ratio of the significant variables. The score summation defined the risk summation. A total of 19.7% of the patients were pT3, 24.2% had a Gleason score ≥ 8, and 26.3% had positive surgical margins. The median follow-up was 82 months. Some 26.6% of the patients experienced biochemical recurrence. The identified prognostic variables independent of biochemical recurrence were a Gleason score =7 (4+3) (HR, 2.01; P=.008), a Gleason score ≥ 8 (HR, 3.07; P 50% survival free of biochemical recurrence at 5 and 8 years. In contrast, the patients with a risk summation ≥ 3 had <44% survival free of biochemical recurrence. The patients with a risk summation ≤ 2 did not benefit from adjuvant radiation therapy, while the patients with a risk summation ≥ 3 might benefit from adjuvant radiation therapy.

    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.

    Full Text Available Abstract Background The role of adjuvant chemoradiation therapy for ampullary carcinoma is unknown. Previous literature suggests that certain populations with high risk factors for recurrence may benefit from adjuvant chemoradiation. We combined the experience of two institutions to better delineate which patients may benefit from adjuvant chemoradiation. Methods Patients who underwent curative surgery for ampullary carcinoma at the Johns Hopkins Hospital (n = 290; 1992-2007 and at the Mayo Clinic (n = 130; 1977-2005 were reviewed. Patients with Results Median overall-survival was 39.9 months with 2- and 5-year survival rates of 62.4% and 39.1%. On univariate analysis, adverse prognostic factors for overall survival included T3/T4 stage disease (RR = 1.86, p = 0.002, node positive status (RR = 3.18, p Conclusions Node-positive patients with resected ampullary adenocarcinoma may benefit from 5-FU based adjuvant chemoradiation. Since a significant proportion of patients develop metastatic disease, there is a need for more effective systemic treatment.

    Worse treatment outcomes can be expected with prolongation of the overall treatment time (OTT) during definitive chemoradiation therapy (CRT) for cervical cancer. In the adjuvant setting, data on the relative importance of the OTT and the importance of RT and chemotherapy synchronization are scarce. Using the National Cancer Database, we evaluated the effect of these treatment variables on overall survival in the adjuvant CRT setting. The present analysis included nonmetastatic cervical cancer patients undergoing hysterectomy followed by adjuvant CRT. The proportional hazard model was used to estimate the effect of prognostic factors (age, comorbidity, race, tumor size, tumor grade, tumor histologic type, number of high-risk pathologic factors) and time-related variables (surgery to RT start interval [SR], OTT [RT start to end dates], package time [from diagnosis date to CRT end date] and optimum CRT synchronization [whether chemotherapy and RT start dates coincided]) on survival. Of 3051 patients, 60% finished RT within 7 weeks and 85% received optimum CRT. Among other factors, univariate analysis identified longer OTT (hazards ratio [HR] 1.33; P7 weeks remained a significant factor even after propensity score matching (P=.04). The results of our analysis suggest that prolongation of the adjuvant CRT duration >7 weeks is associated with poor survival and SR of <8 weeks should be attempted whenever clinically feasible.

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

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

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

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

    Full Text Available The emergence of malarial resistance to most antimalarial drugs is the main factor driving the continued effort to identify/discover new agents for combating the disease. Moreover, the unacceptably high mortality rate in severe malaria has led to the consideration of adjuvant therapies. Senna singueana leaves are traditionally used against malaria and fever. Extracts from the leaves of this plant demonstrated in vitro and in vivo antioxidant activities, which in turn could reduce the severity of malaria. Extracts from the root bark of this plant exhibited antiplasmodial activity; however, the leaves are the more sustainable resource. Thus, S. singueana leaf was selected for in vivo evaluation as a potential alternative or adjuvant therapy for malaria. Using malaria [Plasmodium berghei ANKA, chloroquine (CQ sensitive]-infected Swiss albino mice of both sexes, 70% ethanol extract of S. singueana leaves (alone and in combination with CQ was tested for antimalarial activity and adjuvancy potential. The 4-day suppressive test was used to evaluate antimalarial activity. The dose of S. singueana extract administered was safe to mice and exhibited some parasite suppression effect: extract doses of 200 mg/kg/d, 400 mg/kg/d, and 800 mg/kg/d caused 34.54%, 44.52%, and 47.32% parasite suppression, respectively. Concurrent administration of the extract with CQ phosphate at varied dose levels indicated that the percentage of parasite suppression of this combination was higher than administering CQ alone, but less than the sum of the effects of the extract and CQ acting separately. In conclusion, the study indicated that 70% ethanol extract of S. singueana leaf was safe to mice and possessed some parasite suppression effect. Coadministration of the extract with CQ appeared to boost the overall antimalarial effect, indicating that the combination may have a net health benefit if used as an adjuvant therapy.

    Pathological hypersexuality developed in 13 patients with PD and two patients ultimately diagnosed clinically with MSA. Hypersexuality began within 8 months after starting dopamine agonist therapy in 14 of 15 cases, including four on agonist monotherapy. It resolved in the four cases where the agonist was stopped, despite continued levodopa therapy. This was not an isolated behavioral problem in most, with additional compulsive or addictive behaviors coinciding in nine patients (60%). A systematic literature review of pathological hypersexuality in PD revealed similar medication histories; combining these cases with our series, 26 of 29 patients (90%) were on adjuvant dopamine agonists.

    To determine if utilization of surveillance or adjuvant chemotherapy has increased compared with that of adjuvant radiotherapy (ART) in clinical stage I seminoma (CSIS) and to estimate the impact of this utilization trend on secondary malignancies. The National Cancer Data Base, a web-based data analysis tool was examined for first-course adjuvant therapy management in CSIS from 2000 to 2008. We assessed the utilization in academic vs community practice settings and changes in tumor stage. We also estimated the number of secondary malignancies based on the change in practice. There were 52,672 patients of testicular cancer diagnosed. Of those, 28,974 (55.0%) patients had seminoma with 22,210 (84.2%) patients classified as CSIS. Overall, 14,005 (65.4%), 6430 (30.1%), and 951 (4.4%) patients received ART, surveillance, and adjuvant chemotherapy (AC), respectively. In 2000, most patients received ART (71.7%), followed by surveillance (26.5%), and AC (1.9%). In 2008, the majority of patients still received ART (47.7%) but surveillance (39.6%) and AC (12.6%) totaled a larger proportion. We calculated that this ART utilization rate would lead to an additional 372 solid tumor cases per year, 40 years later, whereas the current surveillance rate would lead to 34 cases of secondary malignancy annually in the United States. ART was the leading adjuvant management strategy for CSIS, but its share drastically decreased with a concomitant increase in surveillance and AC, particularly after 2004. These trends were similar in both academic and community settings. The current level of ART, although decreasing, may nevertheless lead to additional cases of solid cancer comparable with testicular cancer deaths. Published by Elsevier Inc.

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

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

    Propolis is a bee-metabolized resinous substance (bee glue) from plant sap and gums. It has been in usage as a healing agent since antiquity, yet has not garnered global popularity as a health promoter. Its biological effects, which range from antimicrobial, antioxidant, anti-inflammatory, antidiabetic, dermatoprotective, anti-allergic, laxative and immunomodulatory to anticancer, have been validated. Propolis has shown efficacy against brain, head and neck, skin, breast, liver, pancreas, kidney, bladder, prostate, colon and blood cancers. The inhibition of matrix metalloproteinases, anti-angiogenesis, prevention of metastasis, cell-cycle arrest, induction of apoptosis and moderation of the chemotherapy-induced deleterious side effects have been deduced as the key mechanisms of cancer manipulation. The components conferring antitumor potentials have been identified as caffeic acid phenethyl ester, chrysin, artepillin C, nemorosone, galangin, cardanol, etc. These compounds target various genetic and biochemical pathways of cancer progression. Depending on the botanical sources and the geographical origin, biological activities of propolis vary. Despite phenomenal development in cancer research, conventional therapy falls short in complete malignancy management. The findings obtained so far build hope that propolis as a complementary medicine may address the lacunae. This review documents the recent advances and scope of amendement in cancer remediation with adequate emphasis on the mechanistic aspect of propolis.

    Full Text Available Tibetan medicated-bath therapy has been applied to patients with rheumatoid arthritis for centuries. However, the detailed action mechanism of Tibetan medicated-bath therapy on the morphology and function of joints remains unknown. We designed our investigation to evaluate the efficacy of Tibetan medicated-bath therapy on adjuvant arthritis (AA of rats in comparison with water-bath and dexamethasone administration. AA was induced by intradermal injection of Mycobacterium butyricum suspended in sterile mineral oil. The control animals were similarly injected with sterile vehicle. Eight days after injection, rats were treated with fresh-water bath, Tibetan medicated-bath (40°C, 15 min or intramuscular injection with dexamethasone for 21 consecutive days after which we evaluated the severity of arthritis visually and microscopically and measured serum interleukin (IL-6 and tumor necrosis factor (TNF-α levels. While arthritis did not significantly change after water-bath treatment, the Tibetan medicated-bath and dexamethasone groups showed diminished joint swelling and alleviation of, inflammatory cell infiltration and the destruction of bone and cartilage. Serum IL-6 and TNF-α levels significantly decreased. Our results demonstrated that Tibetan medicated-bath therapy exerted a reliable effect on rat adjuvant arthritis, which may be involved in the inflammatory cytokines, IL-6 and TNF-α. Our data provide evidence for clinical use of Tibetan-medicated bath therapy for arthritis patients.

    Full Text Available The choice of adjuvant hormonal therapy in postmenopausal women with hormone receptor positive breast cancer has remained a matter of controversy and debate. The variety of agents is available, with each claiming to be superior. This clinical survey was undertaken to get an impression of the physician’s first choice of therapy in an attempt to find out what questions still need to be answered in the making of “standard of care.” A web-based clinical survey was sent to the cancer physicians around the world, and 182 physicians responded to the survey. Most were medical oncologists in a tertiary care hospital. 36.3% preferred Anastrozole, 35.2% Tamoxifen, and 22.2% Letrozole as their first choice. Data support (67.8% and safety concerns (30% were given as the main reasons for the choice, 63.7% switched their therapy, and 24% had to switch because of side effects. 73.6% used 5 years of adjuvant hormonal therapy, 6.6% for 7 years, and 4.4% for 10 years. 61.5% follow their patients 3 times monthly, and 73.2% used laboratory and radiological assessment at each followup. Conclusion. Physicians show disagreement over the choice and duration of hormonal therapy in this patient population. Clinical trials leading to firm recommendations to set standards from which patients benefit the most are needed.

    Adjuvant endocrine therapy is recommended for women with oestrogen receptor-positive breast cancer, but many women do not take the medication as directed and they stop treatment before completing the standard 5-year duration. This retrospective cohort study conducted between 1993 and 2008 of all women with incident breast cancer, who are residing in the Tayside region of Scotland, examined adherence to prescribed adjuvant tamoxifen or aromatase inhibitors (AIs). Survival analysis examined the effect of adherence on all-cause mortality, breast cancer death and recurrence, using linked prescribing, cancer registry, clinical cancer audit, hospital discharge and death records. A total of 3361 women with breast cancer were followed for a median 4.47 years (interquartile range (IQR)=2.04-8.55). The median overall adherence was 90% (IQR=90-100%), but the annual adherence reduced after a longer period from diagnosis. Low adherence of adherence over the treatment period and recurrence, or breast cancer death, but patients with high annual adherence for 5 years had better outcomes than those with 3 or less. Low adherence to all adjuvant endocrine therapy for women with breast cancer, whether tamoxifen or AI, increases the risk of death.

    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.

    Numerous studies have indicated that in cancer treatment Chinese herbal medicines in combination with chemo- or radio-therapy can be used to enhance the efficacy of and diminish the side effects and complications caused by chemo- and radio-therapy. Therefore, an understanding of Chinese herbal medicines is needed by physicians and other health care providers. This review provides evidence for use of Chinese herbal medicines as adjuvant cancer treatment during chemo- or radio-therapy. First, Chinese herbal medicines (e.g. Astragalus, Turmeric, Ginseng, TJ-41, PHY906, Huachansu injection, and Kanglaite injection) that are commonly used by cancer patients for treating the cancer and/or reducing the toxicity induced by chemo- or radio-therapy are discussed. Preclinical and clinical studies have shown that these Chinese herbal medicines possess great advantages in terms of suppressing tumor progression, increasing the sensitivity of chemo- and radio-therapeutics, improving an organism's immune system function, and lessening the damage caused by chemo- and radio-therapeutics. Second, clinical trials of Chinese herbal medicines as adjuvant cancer treatment are reviewed. By reducing side effects and complications during chemo- and radio-therapy, these Chinese herbal medicines have a significant effect on reducing cancer-related fatigue and pain, improving respiratory tract infections and gastrointestinal side effects including diarrhea, nausea, and vomiting, protecting liver function, and even ameliorating the symptoms of cachexia. This review should contribute to an understanding of Chinese herbal medicines as adjuvant treatment for cancer and provide useful information for the development of more effective anti-cancer drugs.

    Postherpetic neuralgia is a frequent adverse event in herpes zoster patients and difficult to treat. Conventional analgetic therapy often fails to reduce the burning pain transmitted by unmyelinated nerve fibers. These nerves express cannabinoid receptors which exert a role in modulation of nociceptive symptoms. Therefore, topical therapy with cannabinoid receptor agonist seems likely to suppress local burning pain. In an open-labeled trial, 8 patients with facial postherpetic neuralgia received a cream containing the cannabinoid receptor agonist N-palmitoylethanolamine. The course of symptoms was scored with the visual analog scale. 5 of 8 patients (62.5 %) experienced a mean pain reduction of 87.8 %. Therapy was tolerated by all patients. No unpleasant sensations or adverse events occurred. Topical cannabinoid receptor agonists are an effective and well-tolerated adjuvant therapy option in postherpetic neuralgia.

    Adjuvant hormonal therapy is recommended for women with hormone receptor (HR)-positive breast cancer. Though critical, many patients are non-adherent to this therapy. Few scales have been developed to specifically address beliefs about adjuvant hormonal therapy. This study explores the clarity and relevance of the Beliefs about Medicine Questionnaire (BMQ) in the context of adherence behaviors to hormonal therapy in Black and White breast cancer survivors. We recruited women diagnosed with HR-positive cancer from the Washington, DC, area. An interviewer administered a standardized survey and conducted a cognitive interview. Participants rated the BMQ across three areas: relevance, difficulty, and clarity. We coded whether the comments identified item level issues: limited applicability, unclear reference, unclear perspective, or wording or tone. In-depth interviews were conducted with women who prematurely discontinued hormone therapy. The sample (n = 30) was equally split between Black and White survivors. On average, women were 57.9 years old (SD = 9.0). Overall 77% rated scale as relevant. Cognitive interviews revealed areas of perceived limited acceptability such as the notion of becoming too dependent or the notion of becoming worse if not taking the medication. Women who discontinued hormonal therapy (n = 2) felt ambivalent towards hormonal therapy as they reported having both positive and negative beliefs about the medication. Our study findings suggest new areas for further research and instrument development to accurately measure self-reported beliefs about hormonal therapy by HR-positive breast cancer survivors.

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

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

    To comprehensively assess the patient and illness or treatment factors that may predict nonadherence to adjuvant endocrine therapy and to explore whether an interaction occurs between these factors in women with breast cancer. Repeated-measures design. The Outpatient Services of the Women's Cancer Program at the University of Pittsburgh Cancer Institute and participants' homes. 91 women with early-stage breast cancer who received endocrine therapy. Adherence was assessed continuously for the first 18 months of endocrine therapy. Patient and illness or treatment factors were assessed at four time points (Time 1 to Time 4). Time 1 (baseline) was within two weeks prior to the initiation of endocrine therapy. Times 2-4 occurred at six-month intervals, as many as 18 months after Time 1. Adherence, patient factors, and illness or treatment factors. Adherence to endocrine therapy declined significantly during the first 18 months of treatment in women with breast cancer. The presence of negative mood and symptoms before starting treatment predicted nonadherence to endocrine therapy over time. Perceptions of financial hardship, symptoms, disease stage, and more complex medication regimens intensified the effect of negative mood on adherence over time. Women with breast cancer may be at risk for nonadherence to prescribed endocrine therapy if they experience depression or anxiety and symptoms prior to initiating therapy. Oncology nurses should be alert to women with breast cancer who are depressed or anxious or who are experiencing symptoms. Management of negative mood and symptoms may result in better adherence.

    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.

  11. Taxane therapy in the adjuvant treatment of breast cancer in Italy: economic evaluation

    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

    Background Women with small nonpalpable breast tumours have an excellent prognosis. The benefit of radiotherapy in this group of low-risk women is unknown. Methods A cohort of 1595 women with stages i–iii invasive breast cancer treated with breast-conserving surgery were followed for local recurrence. Using t-tests, baseline demographic data and tumour characteristics were compared for the women who had palpable (n = 1023) and mammography-detected (n = 572) breast cancers. The 15-year actuarial risk of local recurrence was estimated using a Kaplan–Meier method, stratified for adjuvant radiation therapy (yes or no), tumour palpability (palpable or not), and tumour size (≤1 cm or >1 cm). Hazard ratios (hrs) and 95% confidence intervals (95% cis) were calculated using a multivariate Cox regression model. Results were considered statistically significant if 2-tailed p values were less than 0.05. Results Among women with a nonpalpable tumour, the 15-year actuarial rates of local recurrence were, respectively, 13.9% and 18.3% for those treated and not treated with adjuvant radiation therapy (hr: 0.65; 95%ci: 0.40 to 1.06; p = 0.08). Among women with small nonpalpable breast cancers (≤1.0 cm), the rates were 14.6% and 13.4% respectively (p = 0.67). The absolute reduction in 15-year local recurrence was 11.0% for women with palpable tumours. Conclusions Our results suggest that women with small (<1 cm) screen-detected nonpalpable breast cancers likely derive little benefit from adjuvant radiotherapy; however, an adequately powered randomized trial would be required to make definitive conclusions.

    The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently, many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice, but its action mechanism is uncertain at present. In this study, with the assistance of pediatric practitioners, the automated ribosomal intergenic-spacer analysis (ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants, in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora, which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units (OTUs) shared with the normal control group. Additionally, adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea, but not for the single oral traditional Chinese medicine for infant diarrhea.

    The purpose of this study was to evaluate the differences in stage upon diagnosis, adherence to adjuvant treatment, and recurrence between rural and urban patients with early breast cancer. This retrospective study included 3640 patients with primary breast cancer recruited from 2000 to 2009. Patients who developed recurrence or metastasis were verified by adequate diagnostic imaging modalities and pathology. The χ(2) test was used to compare groups with respect to variables (recurrence and clinicopathologic features). A multivariable Cox proportional hazard regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for breast cancer recurrence risk. Compared with tumors in urban patients, those in rural patients showed higher histologic grade, larger size, more lymphatic metastasis, and higher Ki-67 index; therapy adherence was strongly associated with recurrence in both. Compared with urban patients, the female rural patients had a higher recurrence rate. However, no significant difference in recurrence rates was observed between urban and rural patients following guideline adherence. The results of our study suggest that the later stage upon diagnosis and nonadherence to treatment contribute toward worse breast cancer outcomes among rural patients with breast cancer. Adherence to needed adjuvant therapy could decrease recurrence rates for rural patients with early breast cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

  16. Adjuvant Systemic Therapy in Older Breast Cancer Women: Can We Optimize the Level of Care?

    Directory of Open Access Journals (Sweden)

    Anna Rachelle Mislang

    2015-07-01

    Full Text Available Defining optimal adjuvant treatment for older women with breast cancer is challenged by the lack of level-1 clinical evidence and the heterogeneity of the older population. Nevertheless, recommendations based on reviews of available evidence mainly from retrospective subgroup analyses and extrapolation of study results from younger patients, and expert opinions, may be useful to guide treatment decisions in fit patients. But how can we properly define a “fit” older patient? In clinical practice, age by itself and clinical impression generally drive treatment decision, although the appropriateness of this judgment is under-documented. Such an approach risks overtreatment or, more frequently, undertreatment. A geriatric assessment can be valuable in oncology practice to address this issue. In this review article, we will focus only on systemic treatment and will discuss “standard” adjuvant systemic treatment strategies for fit older breast cancer patients and the role of “personalized” systemic therapy in unfit patients. The concepts conveyed in this review cannot be extrapolated to locoregional therapy.

    The haemophilia treatment centre of the Clinic for Children and Youth Medicine in Jena extends medical care by health-promotion measures, namely: health counselling, adjuvant exercise therapy and school sports. In addition to the regular medical checks at the treatment centre patients are examined regarding physical fitness, joint situation, quality of life in general and disease-specific manner, as well as psycho-social and nutritional behaviour. Findings and medical results of the examinations are integrated into an individual advice on therapy, school sports, and health recommendations. This aimed at strengthening health-related resources and minimizing potential injuries. First long-term evaluation shows an increase of activity behaviour and physical fitness without increasing bleeding rate and maintained joint function.

    The practice of yoga regulates body physiology through control of posture, breathing, and meditation. Effects of yoga on autonomic functions of patients with refractory epilepsy, as quantified by standardized autonomic function tests (AFTs), were determined. The yoga group (n=18) received supervised training in yoga, and the exercise group (n=16) practiced simple routine exercises. AFTs were repeated after 10 weeks of daily sessions. Data were compared with those of healthy volunteers (n=142). The yoga group showed significant improvement in parasympathetic parameters and a decrease in seizure frequency scores. There was no improvement in blood pressure parameters in either group. Two patients in the yoga group achieved normal autonomic functions at the end of 10 weeks of therapy, whereas there were no changes in the exercise group. The data suggest that yoga may have a role as an adjuvant therapy in the management of autonomic dysfunction in patients with refractory epilepsy.

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

    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.

    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.

    Breast cancer and its treatment negatively affect the important aspects of a woman's life such as sexual health, cognitive functions, body image, and weight. Abrupt estrogen deficiency following chemotherapy and/or hormonal therapy plays an important role in worsening of sexuality. To evaluate the impact of breast cancer treatment on sexual functioning, cognitive function, and body weight in premenopausal women. Thirty-five women with a premenopausal diagnosis of breast cancer who are candidate to adjuvant treatment completed validated questionnaires on menopausal symptoms, sexuality, partner relationship, depression, body image, and cognitive functions after surgery (T0), then after chemotherapy or at least 6 months of endocrine therapy (T1), and after 1 year (T2). In addition, gynecological and dietological examinations were performed. The following validated questionnaires were used: Greene Climacteric Scale, Beck Depression Inventory, Body Attitude Test, McCoy revised Italian version McCoy Female Sexuality Questionnaire, Cues for Sexual Desire Scale, Dyadic Adjustment Scale, Numeric Matrix Test and Rey auditory-verbal learning test, to measure cognitive functions, a recall 24 H questionnaire to evaluate food intake, Minnesota Leisure Time Physical Activity questionnaire and Eating Attitude Test-40, while anthropometric and plicometry data were assessed by a dietitian. Low levels of sexual functioning were registered at baseline; a further decrease in sexual activity, quality of the partnered relationship, desire, and arousability was demonstrated at T1 and T2. We found a significant increase in hot flushes and anxiety. Nonsignificant deterioration of body image was demonstrated. Although women reported losing memory and concentration, "chemobrain" effect was not demonstrated as cognitive tests improved after 6 months, probably because of "learning effect." Women who had undergone chemotherapy gained weight and fat disposition was typically android. Young women

    To assess incidence and degree of regrowth in glioblastoma between surgery and radiation therapy (RT) and to correlate regrowth with presurgical imaging and survival, we examined images of 32 patients with newly diagnosed glioblastoma who underwent MR spectroscopic imaging (MRSI), perfusion-weighted imaging (PWI), and diffusion-weighted imaging (DWI) prior to surgery, after surgery, and prior to RT/temozolomide. Contrast enhancement (CE) in the pre-RT MR image was compared with postsurgical DWI to differentiate tumor growth from postsurgical infarct. MRSI and PWI parameters were analyzed prior to surgery and pre-RT. Postsurgical MRI indicated that 18 patients had gross total and 14 subtotal resections. Twenty-one patients showed reduced diffusion, and 25 patients showed new or increased CE. In eight patients (25%), the new CE was confined to areas of postsurgical reduced diffusion. In the other 17 patients (53%), new CE was found to be indicative of tumor growth or a combination of tumor growth and surgical injury. Higher perfusion and creatine within nonenhancing tumor in the presurgery MR were associated with subsequent tumor growth. High levels of choline and reduced diffusion in pre-RT CE suggested active metabolism and tumor cell proliferation. Median survival was 14.6 months in patients with interim tumor growth and 24 months in patients with no growth. Increased volume or new onset of CE between surgery and RT was attributed to tumor growth in 53% of patients and was associated with shorter survival. This suggests that reducing the time between surgery and adjuvant therapy may be important. The acquisition of metabolic and physiologic imaging data prior to adjuvant therapy may also be valuable in assessing regions of new CE and nonenhancing tumor. PMID:19229057

    Background Cardiotoxicity is an important side effect of trastuzumab therapy and cardiac surveillance is recommended. Objectives The aim of our study was to prospectively assess baseline patients' characteristics, level of N-terminal pro-brain natriuretic peptide (NT-proBNP) and echocardiographic parameters as possible predictors of trastuzumab-related cardiac dysfunction. Methods In a prospective cohort study, clinical, echocardiographic and neurohumoral assessment was performed at baseline, after 4, 8 and 12 months in breast cancer patients undergoing post-anthracycline (3-4 cycles) adjuvant therapy with trastuzumab. Trastuzumab-related cardiac dysfunction was defined as a decline of ≥ 10% in left ventricular ejection fraction (LVEF). Results 92 patients (mean age, 53.6 ± 9.0 years) were included. Patients who developed trastuzumab-related LVEF decline ≥ 10% (20.6%) during treatment had significantly higher baseline LVEF (70.7 ± 4.4%) than those without (64.8 ± 5.5%) (p = 0.0035). All other measured baseline parameters (age, body mass index, arterial hypertension, level of NT-proBNP and other echocardiographic parameters) were not identified as significant. Conclusions Our findings suggest that baseline patient' characteristics, level of NT-proBNP and echocardiographic parameters, as long as they are within normal range, are not a reliable tool to predict early trastuzumab-related cardiac dysfunction in patients undergoing post-low dose anthracycline adjuvant trastuzumab therapy. A LVEF decline in patients with high-normal baseline level although statistically significant is not clinically relevant. PMID:27305108

    A therapeutic strategy that can eliminate primary tumours, inhibit metastases, and prevent tumour relapses is developed herein by combining adjuvant nanoparticle-based photothermal therapy with checkpoint-blockade immunotherapy. Indocyanine green (ICG), a photothermal agent, and imiquimod (R837), a Toll-like-receptor-7 agonist, are co-encapsulated by poly(lactic-co-glycolic) acid (PLGA). The formed PLGA-ICG-R837 nanoparticles composed purely by three clinically approved components can be used for near-infrared laser-triggered photothermal ablation of primary tumours, generating tumour-associated antigens, which in the presence of R837-containing nanoparticles as the adjuvant can show vaccine-like functions. In combination with the checkpoint-blockade using anti-cytotoxic T-lymphocyte antigen-4 (CTLA4), the generated immunological responses will be able to attack remaining tumour cells in mice, useful in metastasis inhibition, and may potentially be applicable for various types of tumour models. Furthermore, such strategy offers a strong immunological memory effect, which can provide protection against tumour rechallenging post elimination of their initial tumours.

    There is increasing interest in the use of decision aids (DAs) to facilitate patient involvement in clinical decisions. This study explored the views of patients with colorectal cancer and participants in a community bowel screening service regarding an interactive DA concerning adjuvant treatment for rectal cancer, and the impact of the aid on knowledge, anxiety, attitudes and preferences for treatment options. Fourteen patients with colorectal cancer participated in four focus groups. Eighty-nine participants in a community bowel screening service completed a questionnaire before and 1 week after viewing the DA. Thirty were randomly selected to participate in a telephone interview to obtain qualitative feedback about the DA. Focus group participants reported using information to evaluate their doctor's care and expertise, or to prepare themselves for future symptoms and side-effects. Most supported the use of a DA and preferred pie charts to convey risk information. Within the community sample, anxiety remained stable and knowledge increased after exposure to the DA. Almost all participants found the DA useful and easy to understand, and felt it would make the process of decision making easier. A DA regarding adjuvant therapy for rectal cancer appears to be valued and to produce positive outcomes. A randomized controlled trial of this intervention is now required.

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

    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.

    Full Text Available Molecular genetic analysis identified some biological subtypes of breast cancer (BC: luminal A, luminal B, HER2 positive, and basal-like (including triple negative. The surrogate clinical and morphological criteria including the immunohistochemical determination of estrogen and progesterone receptors, the hyperexpression and/or amplification of HER2, Ki-67, or tumor grade (G are used to identify the biological subtypes of BC in clinical practice. The biological subtypes are distinguished by their biological course and susceptibility to various systemic treatments, which requires different therapeutic tactics. The paper presents tactics of adjuvant therapy for BC in relation to its biological subtype according to the recommendations of the 12th St. Gallen International Breast Cancer Conference (2011 and considers the place of taxans.

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

    Although a benign disorder, pigmented villonodular synovitis (PVNS) has a high rate of recurrence. Because of the high incidence of recurrence and concern about destruction of the affected joint, several adjuvant therapies have been promoted without a clear standard treatment strategy. We reviewed cases of PVNS affecting the ankle and hindfoot joints (ankle and/or subtalar joints) treated with surgical resection without adjuvant therapy in an effort to identify the incidence of PVNS recurrence after excision without adjuvant therapy. Of the 10 cases with a mean follow-up duration of 33.2 ± 19.8 months, 4 (40%) developed a recurrence, with a mean interval of 6 (range 3 to 14) months. At the final follow-up visit, the mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score was 86.6 ± 12. The clinical outcomes of PVNS affecting the ankle and hindfoot joints are associated with a relatively high incidence of recurrence, and additional clinical investigation comparing the incidence of recurrence in patients undergoing excision versus excision with adjuvant therapy is needed for us to better understand this condition and provide more informed recommendations to our patients.

    The aim of this study was to investigate the role of ultrasonographic microvascular imaging in the evaluation of prognosis of patients with invasive breast cancer treated by adjuvant therapies. A total of 121 patients with invasive breast cancer underwent ultrasonographic contrast-enhanced imaging, vascular endothelial growth factor (VEGF) staining, and microvessel density (MVD) counts. The parameters of microvascular imaging and the expression of VEGF and MVD in primary breast cancer were calculated. The correlation between these factors and the overall and progression-free survival rate were analyzed using the Kaplan-Meier method. Among 121 cases, the positive VEGF cases were 75 and negative ones were 46. The cut point of 52.3 was calculated by the regressive curve for MVD counts. The data showed the mean intensity (MI) was positively associated with both the MVD counts (r = .51, p prognosis of patients, high VEGF expression and MVD counts were associated with reduced progressive and survival times (PFS, p = .032 and p = .034; OS, p = .041 and p = .038, respectively). The correlation between parameters of microvascular imaging, VEGF expressive status, and the MVD counts were established. The cut point of mean intensity (MI = 40) was used to investigate as an independent predictor for PFS (p = .021) and OS (p = .025), respectively, due to a strong correlation between MVD counts and VEGF expression in patients with invasive breast cancer. The microvascular imaging could be a visual and helpful tool to predict the prognosis of patients with invasive breast cancer treated by adjuvant therapies.

    Full Text Available Aim. To evaluate the behavioral effects of lamotrigine as add-on therapy in treatment-resistant epilepsy. Methods. An open, prospective, long-term study of lamotrigine as adjuvant therapy was performed in 56 patients with drug-resistant epilepsy (female/male ratio 35/21, age range 16-51 years. All the patients kept seizure diaries, and electroencephalograms were recorded at baseline and during 24 months of the treatment. Quality of life questionnaire, Hamilton depression scale (HMD, Beck depression scale (BDI, and Hamilton anxiety scale (HMA were used before and during lamotrigine therapy. Comparative assessments were made in an age- and sex-matched control group treated with other antiepileptic drugs. Results. Overall, seizure control was improved in 55.3% of the patients, remained unchanged in 39.3%, and deteriorated in 5.4%. Improvement in some quality of life measures occurred in 50% of the patients. The HMD subscales and BDI scale showed significant improvement in lamotrigine treated patients compared to the control group (ANOVA, p < 0.01. Negative behavioral effects occurred in 10.7% of the patients. Conclusion. Lamotrigine demonstrated significant antiepileptic long-term efficacy, and its positive effects on the mood and quality of life, which surpassed the negative behavioral effects, and contributed highly to the favorable treatment outcome.

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

Adjuvant radiotherapy was defined as postoperative external beam radiation to the pelvis (30–50 Gray/10–25 fractions at five fractions/week. The primary end point was LRFFS, and the secondary end point was OS. Kaplan–Meier curves were compared using the log-rank test. Cox regression analyses were used to determine prognosticators for LRFFS and OS.Results: The median follow-up time of all patients was 75 months, with a 5-year LRFFS of 62.1%. The 2-year and 5-year LRFFS rates were longer for those who received AR than for those who did not receive AR (83.4% vs 70.3%; 78% vs 55.3%; P=0.013. The 5-year OS of all patients was 56.2%, and no significant differences were observed in the 2-year and 5-year OS rates between these two groups (82.7% vs 71.4%; 64.1% vs 51.7%; P=0.067. Importantly, in patients with leiomyosarcoma, the 2-year and 5-year LRFFS and OS rates were longer for those who received AR than for those who did not receive AR (P=0.04 and P=0.02 for the 2-year and 5-year LRFFS, respectively.Conclusion: Patients with uterine sarcoma who were treated with AR after surgery demonstrated an improved LRFFS compared with those who were treated with surgery alone, especially those patients with leiomyosarcoma.

    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.

  5. Extracorporeal Shock Wave Therapy could be a Potential Adjuvant Treatment for Orthopaedic Implant-associated Infections

    Directory of Open Access Journals (Sweden)

    Xiao-feng Chen

    2013-07-01

    Full Text Available Over the past half-century, biomaterials have been used in orthopaedic surgery world widely, but orthopaedic implant-associated infections (OIAIs are still a puzzle for orthopaedic surgeons, which may result in prolonged hospitalisation, poor functional status and high costs. The presence of implants increases the risk of microbial infection; moreover, the formation of bacterial biofilm leads to a higher resistance to antibiotics and local immune response. In such cases, conventional systemic delivery of drugs seems to be fairly inefficient and out-dated. Owing to this, debridement and/or removing the implant always become the only solution. Hence, it needs a simple, minimally invasive and effective therapy to eradicate the problem. There are abundant evidences showing that extracorporeal shock wave therapy (ESWT has favourable effects on stimulating callus formation, inducing angiogenesis, promoting osteogenesis and relieving pain. Studies also indicated that ESWs have a significant bactericidal effect on bacterial strains of bone- and implant-associated infections. Therefore, a hypothesis proposed herein is that ESWT may well be an effective adjuvant treatment for OIAI by controlling infection, inducing bone regeneration and promoting re-osseointegration.

    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.

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

    Hormonal therapy with either tamoxifen or aromatase inhibitors is commonly used to treat women with breast cancer in both the adjuvant and recurrent disease setting. Cutaneous adverse reactions to these drugs have been rarely reported in the literature. We report an unusual case of urticarial vasculitis following the aromatase inhibitor anastrozole that localised to the unilateral trunk and mastectomy scar, and review the literature on the cutaneous adverse effects of hormonal therapy for breast cancer.

    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.

    Breast cancer survivors often receive long-term adjuvant endocrine therapy (AET) to reduce recurrence risk. Adherence to AET is suboptimal, which may be due to the experience of symptoms and/or concerns. Few studies have comprehensively assessed self-reported concerns between those who currently, previously or have never received AET. The study objective is to describe self-reported physical and emotional concerns of breast cancer survivors who are current, prior, or never-recipients of AET. Secondary analysis was performed on a subset of survey data collected in the 2010 LIVESTRONG Survey. Breast cancer survivors (n = 1,013, mean 5.4 years post-diagnosis) reported on 14 physical and eight emotional concerns that began after diagnosis and were experienced within 6 months of participation in the survey. Bivariate analyses examined the prevalence of each concern by AET status. The relationships between AET and burden of physical or emotional concerns were modeled with logistic regression. More than 50% of the participants reported currently experiencing cognitive issues, fatigue, fear of recurrence, emotional distress, and identity/grief issues. Thyroid dysfunction and stigma concerns were more common among participants with prior AET (p physical, but not emotional concerns. A higher number of concerns was associated with younger age, having children, receipt of chemotherapy, longer duration of cancer treatment, and shorter time since diagnosis (p physical and emotional concerns, many of which persisted after treatment. These findings suggest the importance of developing individualized, supportive resources for breast cancer survivors.

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

    Adherence to adjuvant endocrine therapy (AET) following breast cancer is known to be suboptimal despite its known efficacy in reducing recurrence and mortality. This study aims to investigate factors associated with non-adherence and inform the development of interventions to support women and promote adherence. A questionnaire survey to measure level of adherence, side effects experienced, beliefs about medicine, support received and socio-demographic details was sent to 292 women 2-4 years post breast cancer diagnosis. Differences between non-adherers and adherers to AET were explored, and factors associated with intentional and unintentional non-adherence are reported. Approximately one quarter of respondents, 46 (22%), were non-adherers, comprising 29 (14%) intentional non-adherers and 17 (8%) unintentional non-adherers. Factors significantly associated with intentional non-adherence were the presence of side effects (p adherence were younger age (adherence and unintentional non-adherence. Differentiation between the two types of non-adherence may help tailor support and advice interventions. © 2016 John Wiley & Sons Ltd.

    Breast cancer incidence and mortality are declining due to improvements in early detection and treatment. One advance in treatment is the development of adjuvant endocrine therapy (AET) for women with hormone receptor positive breast cancer. Despite strong evidence linking AET to better health outcomes, AET adherence continues to be suboptimal. This study tests the hypothesis that patient beliefs about medication mediate the relationship between frequency of physician communication and AET adherence. This cross-sectional study utilizes data from patient self-report and medical chart abstraction (N=200). Survey measures included frequency of physician communication, patient beliefs about medicine, AET adherence, and demographic characteristics. Necessity beliefs mediated the relationship between frequency of physician communication and medication adherence (necessity beliefs β=.18, p.05). There was no evidence of medication concerns mediating the relationship between frequency of physician communication and medication adherence. More frequent physician communication that shapes what patients believe about AET importance may be associated with greater AET adherence; however, frequent physician communication that shapes patient concerns about side effects may not be associated with greater AET adherence. Research is needed to enhance understanding of the type of physician communication that is most consistently associated with patient beliefs about medication and AET adherence.

    Bone loss is a significant clinical problem for female cancer survivors (FCS) and increases fracture risk. The aim of the Yale Fitness Intervention Trial (Yale FIT) was to determine the effects of a 12-month aerobic-resistance exercise intervention compared to a home-based physical activity group on bone outcomes [bone mineral density (BMD)] and biomarkers bone turnover). Early postmenopausal FCS (N = 154) were randomized to the exercise intervention (3 times/week) or to a home-based physical activity group. Calcium (1200 mg) and Vitamin D (400 IU) supplements were provided to both groups. BMD was measured at baseline and 12 months. No significant difference in BMD was observed for the exercise vs home-based group. However, subjects on Tamoxifen or no endocrine therapy did not significantly lose BMD, with the exception of the femoral neck (FN). In contrast subjects on aromatase inhibitors (AIs) had significant BMD loss at all sites. The majority of subjects had sufficient serum levels of Vitamin D (>20 ng/mL) but there was significantly less bone loss in subjects in the 20-29 ng/mL range at the LS (p = 0.01), hip (p = 0.03), and GT (p = 0.008) compared to lower or higher levels. Exercise stimulates bone remodeling but the intervention was not superior for BMD outcomes at one year. The dose of the osteogenic stimulus in the intervention has been effective in preserving BMD in healthy postmenopausal women but it may be inadequate for survivors with chemotherapy-induced menopause and for those on adjuvant AI therapy.

    Photodynamic therapy (PDT) is known to alter the expression of various genes in treated cells. This prompted us to examine the activity of genes encoding two important enzymes in sphingolipid (SL) metabolism, dihydroceramide desaturase (DES) and sphingosine kinase (SPHK), in mouse SCCVII tumor cells treated by PDT using either the porphyrin-based photosensitizer Photofrin or silicon phthalocyanine Pc4. The results revealed that PDT induced an upregulation in the expression of two major isoforms of both genes (DES1 and DES2 as well as SPHK1 and SPHK2). While the changes were generally moderate (2-3-fold gains), the increase in DES2 expression was more pronounced and it was much greater with Photofrin-PDT than with Pc4-PDT (over 23-fold vs. less than 5-fold). Combining either Photofrin-PDT or Pc4-PDT with the cationic C16-ceramide LCL30 (20mg/kg i.p.) for treatment of subcutaneously growing SCCVII tumors rendered important differences in the therapy outcome. Photofrin-PDT, used at a dose that attained good initial response but no tumor cures, produced 50% cures when combined with a single LCL30 treatment. In contrast, the same LCL30 treatment combined with Pc4-PDT had no significant effect on tumor response. The optimal timing of LCL30 injection was immediately after Photofrin-PDT. The therapeutic benefit was lost when LCL30 was given in two 20mg/kg injections encompassing intervals before and after PDT. LCL85, the cationic B13 ceramide analogue and SL-modulating agent, also increased cure rates of Photofrin-PDT treated tumors, but the therapeutic benefit was less pronounced than with LCL30. These results with LCL30 and LCL85, and our previous findings for LCL29 (another SL analogue), assert the potential of SLs for use as adjuvants to augment the efficacy of PDT-mediated tumor destruction.

    Cytomegalovirus (CMV) reactivation is a clinically significant complication in hematopoietic stem cell transplant (HCT) recipients. Alternative therapy for multidrug-resistant CMV is limited and often fails. Leflunomide has been used to treat resistant CMV infections, however, data on efficacy, safety, and guidance for therapeutic drug level monitoring are lacking. In this report, we describe 3 HCT recipients with multi-drug resistant CMV infections who received leflunomide as adjuvant and salvage therapy. The therapeutic effect of leflunomide as an anti-CMV agent based on virologic responses and therapeutic drug monitoring were evaluated.

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

    Background/Aims: In patients with colon cancer who undergo resection for potential cure, 40–60% have advanced locoregional disease (stage III). Those who are suitable for adjuvant treatment had a definite disease-free-survival benefit. The aim of the present study was to demonstrate whether the presence of desmoplasia influenced the mortality rate of stage III colorectal cancer (CRC) within 5 years from the surgery and adjuvant therapy. Patients and Methods: Sixty-five patients with stage III CRC underwent resection and adjuvant therapy. Qualitative categorization of desmoplasia was obtained using Ueno's stromal CRC classification. Desmoplasia was related to mortality using Spearman correlation and stratified with other histological variables (inflammation, grading) that concurred to the major determinant of malignancy (venous invasion and lymph nodes) using the Chi-square test. Result: The 5-year survival rate was 65% and the relapse rate was 37%. The mortality rate in patients with immature desmoplasia was 86%, 27% in intermediate desmoplasia, and 0% in mature desmoplasia (Spearman correlation coefficient: −0.572, P = 0.05). Conclusion: Immature desmoplasia appears to be associated with disease recurrence and mortality in stage III CRC patients. PMID:28139499

Result: The 5-year survival rate was 65% and the relapse rate was 37%. The mortality rate in patients with immature desmoplasia was 86%, 27% in intermediate desmoplasia, and 0% in mature desmoplasia (Spearman correlation coefficient: −0.572,P= 0.05. Conclusion: Immature desmoplasia appears to be associated with disease recurrence and mortality in stage III CRC patients.

    In patients with colon cancer who undergo resection for potential cure, 40-60% have advanced locoregional disease (stage III). Those who are suitable for adjuvant treatment had a definite disease-free-survival benefit. The aim of the present study was to demonstrate whether the presence of desmoplasia influenced the mortality rate of stage III colorectal cancer (CRC) within 5 years from the surgery and adjuvant therapy. Sixty-five patients with stage III CRC underwent resection and adjuvant therapy. Qualitative categorization of desmoplasia was obtained using Ueno's stromal CRC classification. Desmoplasia was related to mortality using Spearman correlation and stratified with other histological variables (inflammation, grading) that concurred to the major determinant of malignancy (venous invasion and lymph nodes) using the Chi-square test. The 5-year survival rate was 65% and the relapse rate was 37%. The mortality rate in patients with immature desmoplasia was 86%, 27% in intermediate desmoplasia, and 0% in mature desmoplasia (Spearman correlation coefficient: -0.572,P= 0.05). Immature desmoplasia appears to be associated with disease recurrence and mortality in stage III CRC patients.

    Purpose Atypical femoral fracture (AFF), periprosthetic femoral fracture (PPFF) and femoral nonunion (FNU) are recalcitrant challenges for orthopedic surgeons. Teriparatide (TPTD) had been demonstrated to have anabolic effects on bone in various studies. We postulated that adjuvant TPTD after operation would enhance biologic stimulation for bone formation. We investigated (1) whether the adjuvant TPTD could achieve satisfactory union rate of surgically challenging cases such as displaced AFF, PPFF and FNU; (2) whether the adjuvant TPTD could promote development of abundant callus after surgical fixation; (3) whether the adjuvant TPTD had medically serious adverse effects. Materials and Methods Thirteen patients who agreed to off label use of TPTD in combination of operation were included in this retrospective case series. Median patients' age was 68.7 years, and there were three male and ten female patients. Their diagnoses were nonunion in six patients and acute fracture in seven. Medical records and radiographic images were reviewed. Results Twelve of thirteen fractures were united both clinically and radiologically within a year after adjuvant TPTD. Union completed radiologically median 5.4 months and clinically 5.7 months after the medication, respectively. Callus appeared abundantly showing median 1.4 of fracture healing response postoperatively. There was no serious adverse reaction of medication other than itching, muscle cramp, or nausea. Conclusion Even appropriate surgical treatment is a mainstay of treatment for AFF, PPFF, and FNU, the current report suggested that adjuvant TPTD combined with stable fixation results in satisfactory outcome for the challenging fractures of femur.

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

    Full Text Available Objective: The success of oral adjuvant endocrine therapy (OAET is greatly influenced by patients' level of adherence to treatment. The objective of this study is to measure the prevalence and determinants of adherence to OAET among breast cancer patients in Singapore. Methods: A cross-sectional survey of patients supplemented by analysis of their prescription records was used to collect data. Adherence to OAET was assessed using the Morisky Medication Adherence Scale-4 items and evaluation of refill gaps. Univariate and multivariate analyses were done to evaluate the association between patients' characteristics and adherence to OAET. Results: A total of 157 women who have started OAET at least 6 months before the time of interview participated in the study, of which less than half (64 patients, 40.8% of the patients had high adherence. Univariate analysis identified patients who were 57 years or older (P = 0.027, unemployed (P = 0.027, on aromatase inhibitors (P = 0.023, on three or more concurrent medications (P = 0.001, and had one or more comorbidities (P = 0.000 to be significantly more adherent. However, only the number of comorbidities was found to be an independent predictor of adherence in a multiple logistic regression analysis (adjusted odds ratio = 2.60; 95% confidence interval = 1.208–5.593; P = 0.015. Forgetfulness was the main reason for nonadherence mentioned by 63 (67.7% of the 93 nonadherent patients. Conclusions: Low level of OAET adherence was found in this study, and forgetfulness was cited as the main reason for nonadherence. Patients were generally receptive to the implementation of various strategies to assist them with their medication-taking behavior

    To explore differences in opioid use across different adjuvant endocrine therapy (AET) regimens, factors associated with opioid use, and the impact of opioid use on overall survival in female breast cancer patients treated with AET. This retrospective study analyzed 2006-2012 SEER-Medicare datasets, following patients for at least two years from the index date, defined as the first date they filled an AET prescription. The study included adult women with incident, primary, hormone-receptor-positive, stage I-III breast cancer. They were also first-time AET users, and fee-for-service Medicare enrollees continuously enrolled in Medicare Parts A, B, and D. The main independent variable was the AET regimen. We measured whether patients used opioids after the initiation of AET. After the adjustment of inverse probability treatment weights and unbalanced covariates, the average treatment effect probabilities of opioid use were similar between those who used aromatase inhibitors (AI) only and those used tamoxifen (TAM) only (56.2 vs. 55.3%, respectively). Opioid use probabilities for those who switched from AI to TAM were higher than those for the TAM-only and AI-only groups. Opioid use was also significantly associated with AET non-adherence. Opioid users had a significantly higher risk of death (adjusted hazard ratio [HR] = 1.59, p < 0.001). Switching from AI to TAM was associated with a high likelihood of opioid use. Opioid use was significantly associated with AET non-adherence and higher risk of mortality in female Medicare beneficiaries with breast cancer even after adjusting for adherence.

    The effectiveness of PDT as an adjuvant alternative therapy method for diverse malignant tumors has been investigated in numerous studies. The therapeutic benefit and extent of side effects is mainly determined by the applied photoactive substance. The second generation photosensitizer (PS) mTHPC is capable of causing selective tumor cell death in colon carcinoma when combined with laser irradiation of a PS specific wavelength. Our study revealed PDT with mTHPC as an efficient adjuvant intraoperative modality after R1/R2 resection of a subcutaneously implanted colon tumor. There was a significant increase of postoperative recurrence-free survival time using PDT compared to a control group in a colon cancer model in nude mice. The accumulation of the PS determined by point spectrometry showed a high tumor-selectivity in the tumor, tumor bed, and overlying skin compared to muscle tissue as reference parameter.

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

    Adjuvant radiation therapy (RT) was shown to improve local control in patients with high-intermediate risk (HIR) stage I endometrial cancer (EC) in randomized trials. Overall survival (OS) was not significantly different with adjuvant RT in these trials or subsequent meta-analyses; however, they were underpowered to assess OS. We used the National Cancer Data Base (NCDB) to examine the impact of adjuvant RT on OS in HIR EC patients. The NCDB was queried for patients diagnosed with FIGO (2009) Stage I endometrioid adenocarcinoma from 1998 to 2012 who underwent surgery±adjuvant RT. Per ASTRO guidelines, HIR risk was defined as stage IB and/or grade 3. Patients were excluded if: non-surgical primary therapy, RT>180days after surgery, unknown stage/grade/RT status, or RT to targets outside pelvis/vagina. Kaplan-Meier plots and Cox proportional hazards regression were used. 33,600 patients met criteria. 18,070 patients (53.8%) received surgery alone, 15,530 patients (46.2%) received surgery+adjuvant RT. Of patients who received adjuvant RT, 42.2% received external beam RT, 44.7% brachytherapy, and 13.1% received both. 5-year OS was 79.2% for the surgery alone group and 83.3% for the surgery+adjuvant RT (p<0.0001). On multivariate analysis, adjuvant RT was independently associated with improved OS vs. surgery alone (HR 0.7; 95% CI 0.8-0.9, p<0.0001). Our results show that surgery+adjuvant RT was associated with a statistically significant 4.1% improvement in 5-year OS vs. surgery alone in stage I HIR EC. This data along suggests that the improvement in local control with adjuvant RT leads to improved OS. Published by Elsevier Inc.

    Objective: To compare the mechanisms of analgesia induced by four kinds of acupuncture therapies at the hypothalamic level in adjuvant arthritic rats. Methods: Forty-eight SD rats were randomized into normal, model, electroacupuncture (EA), filiform needle (FN), pricking blood-letting (BL) and point injection (PI) groups, with 8 cases in each. EA (20-100 Hz, 2-4 V and duration of 20 min), FN, BL PI were respectively applied to "Kunlun" (昆仑BL 60). Arthritis model was established by injecting complete Freund's adjuvant (0.1 mL) into the rat's right foot pad. Behavioral reactions, pain threshold (latency of tail flick to heat stimulation) and local swelling severity (foot volume) were detected; the contents of β-endorphin (β-EP) and adrenocorticotropin (ACTH) were assayed with radioimmunoassay; and the expression of pro-opi-omelanocortin (POMC) mRNA in hypothalamus were determined with hybridization method. Results: The pain threshold was significantly enhanced by all the four kinds of acupuncture therapies, and the effects of EA and PI were more obvious (P0.05). The content of β-EP in the hypothalamus was obviously elevated by EA and FN (P0.05). The content of ACTH in hypothalamus was considerably elevated by PI (P<0.05), but not by the other three therapies. The expression of POMCmRNA in hypothalamus was significantly strengthened by EA and FN (P<0.01), but not by the other two therapies. Conclusion: EA, filiform needle, blood-letting and point-injection all can produce analgesic effect in adjuvant arthritis rats, the effect of EA and filiform needle may be related to their resultant increase of hypothalamic β-EP, and that of point-injection related to the increase of hypothalamic ACTH level.

    Patients with resected stage II or III melanoma are at high risk of recurrence, with 5-year mortality rate of 40-60%. Adjuvant interferon-alfa has demonstrated a small RFS and OS benefit versus observation in this patient population. However, the adjuvant treatment landscape is evolving rapidly. Areas covered: This review aims to summarize the safety and efficacy profiles of adjuvant IFNα/PEG-IFNα, revisit the controversy surrounding its application, and reappraise its position in the rapidly changing treatment landscape of resected melanoma. A literature search using PubMed database was undertaken using search words melanoma, interferon-alfa, pegylated interferon-alfa, adjuvant therapy. Expert opinion: Currently, there is no international consensus regarding the optimal dosing schedule for adjuvant IFNα, but HD IFNα-2b remains the most widely used regimen. The AEs of HD IFNα-2b are substantial; however, toxicity management experience amassed over the past 2 decades has significantly improved safety. Many exciting studies are ongoing to examine the roles of immune checkpoint inhibitors and BRAF-targeted therapies in the adjuvant setting and will further delineate the role of adjuvant IFNα.

    Full Text Available Malignant salivary gland tumors are rare in children, mostly represented by low-grade mucoepidermoid carcinomas. For these patients, long-term survival rates above 95% are reported after surgical resection. Here we report a case of a 9-year-old girl with a high grade locally advanced mucoepidermoid carcinoma undergoing adjuvant radiotherapy and chemotherapy after surgery. We emphasize the controversy and lack of evidence-based indication for these highly toxic adjuvant therapy modalities in children.

    Adjuvant hormonal therapy is crucial in the treatment of estrogen receptor-positive breast cancer. The nonadherence rate to hormonal treatment is reported to be as high as 60%. The goal of this study was to evaluate the factors evoked by the patients as well as the demographic and disease-related factors that could be associated with nonadherence to adjuvant hormonal therapy. All consecutive patients treated for an estrogen receptor-positive breast cancer who showed up for regular follow-up with a single breast specialist between November 2008 and April 2009 were included in the study. We assessed adherence to hormonal therapy (either with tamoxifen or aromatase inhibitor). Reasons for adherence and nonadherence were collected. Records were also reviewed for demographic and cancer characteristics and for treatment components. We included 161 patients in the study; 150 (93.2%) adhered to hormonal treatment. Side effects and absence of conviction were the main reasons for nonadherence. The importance of the diagnosis of cancer, fear of recurrence and regular follow-up were reported as the main reasons for adherence. Severity of disease and side effects are associated with nonadherence to treatment. Strict follow-up appears to be a necessary adjunct in the adherence to treatment. The association between demographic and cancer characteristics and treatment components needs further investigation. However, these factors may help identify patients at risk of nonadherence and help the oncology team.

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

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

Materials and Methods: A total of 20 patients with a diagnosis of chronic periodontitis (40 localized chronic periodontitis sites were enrolled. None of these patients have previously received any surgical or nonsurgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss. Two nonadjacent sites in separate quadrants were selected in each patient to verify treatment efficacy (split-mouth design. Microbial analysis was analyzed at baseline and the 7 th day after treatment. SPSS program and paired simple statistic t-test were used to detect statistically significant differences. Results: There was a statistically significant reduction of Tannerella forsythia loading in sites treated with ozone therapy respect to those treated with SPR alone. A similar trend was obtained also for additional 5 species and for total bacterial loading (CBT. These results were obtained with a single local application of ozone therapy just after SPR and with a molecular control 7 th day after treatment. Conclusion : Aquolab ® ozone therapy in is effective in reducing the CBT in pockets of patients affected by periodontitis. It is an efficacy medical device to be used as adjuvant therapy to be added to SRP in the management of moderate to severe chronic periodontitis.

    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 18F-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 significance

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

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

    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.

    Adjuvant endocrine therapy has significantly improved survival of estrogen receptor α (ER)-positive breast cancer patients, but around 20% relapse within 10 years. High expression of ER-stimulated proteins like progesterone receptor (PR), Bcl-2 and insulin-like growth factor receptor I (IGF-IR) is a marker for estrogen-driven cell growth. Therefore, patients with high tumor levels of these proteins may have particularly good prognosis following adjuvant endocrine therapy. Archival tumor tissue was available from 1323 of 1396 Danish breast cancer patients enrolled in BIG 1-98, a randomized phase-III clinical trial comparing adjuvant letrozole, tamoxifen or a sequence of the two drugs. Immunohistochemical staining for ER, HER-2, PR, Bcl-2 and IGF-IR was performed and determined by Allred scoring (ER, PR and Bcl-2) or HercepTest (HER-2 and IGF-IR). Data on all five markers were available from 969 patients with ER-positive, HER-2-negative tumors. These patients were classified in ER activity groups based on the level of PR, Bcl-2 and IGF-IR. High ER activity profile was found in 102 patients (10.5%) and compared with the remaining patients, univariate and multivariate analysis revealed HR (95% CI) and p values for disease-free survival (DFS) of 2.00 (1.20-3.22), 0.008 and 1.70 (1.01-2.84), 0.04 and for the overall survival (OS) of 2.33 (1.19-4.57), 0.01 and 1.90 (0.97-3.79), 0.06, respectively. The high ER activity profile did not disclose difference in DFS or OS according to treatment with tamoxifen or letrozole (p = .06 and .09, respectively). Stratifying endocrine-treated patients in ER activity profile groups disclosed that patient with high ER activity profile (10.5%) had significantly longer DFS and OS, and the profile was an independent marker for DFS. High ER activity is a marker for estrogen-driven tumor growth. We suggest further analyses to disclose whether the ER activity profile or other markers associated with estrogen-driven growth may be used to

    of Background Data The effectiveness of adjuvant chemotherapy in patients with stage II/III colorectal cancer has been confirmed in various studies. However, no adjuvant chemotherapy for colorectal liver metastasis (CLM) classified to stage IV has been established. Objectives We conducted a phase 1 study of S-1 and oxaliplatin to determine the recommended dose (RD) in patients with CLM as adjuvant therapy in two institutes. Methods S-1 and oxaliplatin were administered from day 1 to day 14 of a 3-week cycle as a 2-h infusion every 3 weeks, respectively. The initial doses of S-1 and oxaliplatin were fixed to 80 mg/m(2) and 100 mg/m(2), respectively (level 1). We scheduled in the protocol a dose change of S-1 and oxaliplatin to level 2 (S-1: 80 mg/m(2) and oxaliplatin: 130 mg/m(2)) or level 0 (S-1: 65 mg/m(2) and oxaliplatin: 100 mg/m(2)) depending on the incidence of dose-limiting toxicity (DLT) at level 1 in six patients. Results Because DLT occurred in one among the initial six patients at level 1, the doses were increased to level 2 in the next six patients. At level 2, grade 3 leukopenia and neutropenia occurred in one (16.7 %) and two (33.3 %) patients, respectively, in the absence of non-hematological event. Because no DLT occurred at level 2, we suggest that the RD can be set to the level 2 dose. The median number of cycles delivered at RD was 8. The mean relative dose intensity of S-1 and oxaliplatin at RD was 0.90 and 0.63, respectively. Conclusion In a patient undergoing hepatectomy for CLM, 80 mg/m(2) of S-1 and 130 mg/m(2) of oxaliplatin are recommended as adjuvant therapy. A further study is required to confirm the efficacy and safety of this regimen on a larger scale.

    Although clinical trials have demonstrated the benefit of adjuvant hormonal therapy for hormone receptor-positive breast cancer, it is not known whether poor medication adherence might impact outcomes, particularly in the context of a low-income population traditionally underrepresented in clinical trials. We explored the relationship between adherence to tamoxifen or selective aromatase inhibitors with cancer recurrence and death in a low-income, Medicaid-insured population. Using a Medicaid claims-tumor registry and National Death Index data, we evaluated adherence to adjuvant hormonal therapy [defined by the medication possession ratio (MPR)], cancer recurrence, and cancer-specific survival for female breast cancer diagnosed from 1998 to 2002, in North Carolina. Multivariate Cox proportional hazards models and logistic regression models were used to examine the role of adherence on cancer recurrence and survival. The sample consisted of 857 cases, mean age 67.7 years, 56.9% white, 60.9% local stage, with a mean follow-up of 4.4 years. Mean first-year MPR was 77%. MPR adherence was not significantly associated with cancer-related death [adjusted hazards ratio=1.18 (95% confidence interval, 0.54-2.59)], or recurrence [adjusted odds ratio=1.49 (95% confidence interval, 0.78-2.84)]. There was also no significant interaction between adherence and use of concurrent CYP2D6 enzyme inhibitors. Hormonal therapy adherence was not associated with breast cancer outcomes in this low-income population with relatively poor adherence. Although suboptimal adherence is considered to be an important clinical problem, its effects on breast cancer outcomes may be masked by patient genetic profiles, tumor characteristics, and behavioral factors.

    The long-term use of hormonal therapy is important for the treatment of patients with breast cancer. Therefore, we evaluated the methods used for measuring adherence and examined factors that influence compliance. Our goal was to improve overall adherence to the treatment. Retrospective analyses by using electronic medical records and questionnaires were performed on 294 patients with breast cancer. The patients were classified into 2 groups based on the mean number of days when a dose was missed over a period of 28 days: group A(range, 0-3 days, n=272)and group B (range, B4 days, n=22). Factors that may influence adherence, including age, duration of hormonal therapy, the drug administered in hormonal therapy, the surgical method, axillary lymph node dissection, and adjuvant chemotherapy, were compared between both groups. The adherence rates calculated from electronic medical records and questionnaires were similar. The proportion of patients younger than 50 years was 30% in group A and 50% in group B(pcancer-related procedures, such as breast conserving surgery, may also be linked to poor adherence. Young age and long duration of hormonal therapy are possibly related to poor adherence. Therefore, pharmacists should identify and manage these patients to increase adherence.

    In a sample of 368 postmenopausal women, we (1) determined within-cohort and between-cohort relationships between adjuvant systemic therapy for breast cancer and self-reported cognitive function during the first 18 months of therapy and (2) evaluated the influence of co-occurring symptoms, neuropsychological function, and other covariates on relationships. We evaluated self-reported cognitive function, using the Patient Assessment of Own Functioning Inventory (PAOFI), and potential covariates (e.g., co-occurring symptom scores and neuropsychological function z-scores) in 158 women receiving aromatase inhibitor (AI) therapy alone, 104 women receiving chemotherapy followed by AI therapy, and 106 non-cancer controls. Patients were assessed before systemic therapy and then every 6 months, for a total of four assessments over 18 months. Controls were assessed at matched time points. Mixed-effects modeling was used to determine longitudinal relationships. Controlling for covariates, patients enrolled before chemotherapy reported poorer global cognitive function (p cognitive and intellectual functions from before chemotherapy to 12 months after initiation of AI therapy (p cognitive function over time. PAOFI total score was a predictor of executive function (p = 0.048) and visual working memory (p = 0.005) z-scores, controlling for covariates. Findings provide further evidence of poorer self-reported cognitive function after chemotherapy and of relationships between co-occurring symptoms and cognitive changes. AI therapy alone does not have an impact on self-reported cognitive function. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

    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.

    Full Text Available To evaluate the efficacy and safety of bevacizumab in the adjuvant cancer therapy setting within different subset of patients.PubMed, EMBASE, Cochrane and Clinical trials.gov databases were searched for English language studies of randomized controlled trials comparing bevacizumab and adjuvant therapy with adjuvant therapy alone published from January 1966 to 7th of May 2014. Progression free survival, overall survival, overall response rate, safety and quality of life were analyzed using random- or fixed-effects models according to the PRISMA guidelines. We obtained data from 44 randomized controlled trials (30,828 patients. Combining bevacizumab with different adjuvant therapies resulted in significant improvement of progression free survival (log hazard ratio, 0.87; 95% confidence interval (CI, 0.84-0.89, overall survival (log hazard ratio, 0.96; 95% CI, 0.94-0.98 and overall response rate (relative risk, 1.46; 95% CI: 1.33-1.59 compared to adjuvant therapy alone in all studied tumor types. In subgroup analyses, there were no interactions of bevacizumab with baseline characteristics on progression free survival and overall survival, while overall response rate was influenced by tumor type and bevacizumab dose (p-value: 0.02. Although bevacizumab use resulted in additional expected adverse drug reactions except anemia and fatigue, it was not associated with a significant decline in quality of life. There was a trend towards a higher risk of several side effects in patients treated by high-dose bevacizumab compared to the low-dose e.g. all grade proteinuria (9.24; 95% CI: 6.60-12.94 vs. 2.64; 95% CI: 1.29-5.40.Combining bevacizumab with different adjuvant therapies provides a survival benefit across all major subsets of patients, including by tumor type, type of adjuvant therapy, and duration and dose of bevacizumab therapy. Though bevacizumab was associated with increased risks of some adverse drug reactions such as hypertension and bleeding

    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.

    Proteolytic activity and inflammation in the tumour microenvironment affects cancer progression. In colorectal cancer (CRC) liver metastases it has been observed that three different immune profiles are present, as well as proteolytic activity, determined by the expression of urokinase......-type plasminogen activator (uPAR).The main objectives of this study were to investigate uPAR expression and the density of macrophages (CD68) and T cells (CD3) as markers of inflammation in resected CRC liver metastases, where patients were neo-adjuvantly treated with chemotherapy with or without the angiogenesis...... inhibitor bevacizumab. Chemonaive patients served as a control group. The markers were correlated to growth patterns (GP) of liver metastases, i.e. desmoplastic, pushing and replacement GP. It was hypothesised that differences in proteolysis and inflammation could reflect tumour specific growth and therapy...

    Virginal breast hypertrophy is a rapid and massive enlargement of one or both breasts. There are several proposed causes and treatment options for virginal breast hypertrophy, but the investigations to support these theories are lacking. We report two premenarchal girls with virginal breast hypertrophy who presented as different clinical cases. After their surgical interventions, their clinical courses were followed for more than 2 years with tamoxifen as an adjuvant therapy. Breast size and shape disorders can be a disturbing cosmetic problem for adolescents who worry about their body image. A combination treatment of breast reduction surgery and tamoxifen is reasonable and can eliminate the need for repeated surgeries for girls with virginal breast hypertrophy.

    Purpose Outcomes for early-stage breast cancer have improved. First-generation adjuvant chemotherapy trials reported a 0.27% 8-year cumulative incidence of myelodysplastic syndrome/acute myelogenous leukemia. Incomplete ascertainment and follow-up may have underestimated subsequent risk of treatment-associated marrow neoplasm (MN). Patients and Methods We examined the MN frequency in 20,063 patients with stage I to III breast cancer treated at US academic centers between 1998 and 2007. Time-to-event analyses were censored at first date of new cancer event, last contact date, or death and considered competing risks. Cumulative incidence, hazard ratios (HRs), and comparisons with Surveillance, Epidemiology, and End Results estimates were obtained. Marrow cytogenetics data were reviewed. Results Fifty patients developed MN (myeloid, n = 42; lymphoid, n = 8) after breast cancer (median follow-up, 5.1 years). Patients who developed MN had similar breast cancer stage distribution, race, and chemotherapy exposure but were older compared with patients who did not develop MN (median age, 59.1 v 53.9 years, respectively; P = .03). Two thirds of patients had complex MN cytogenetics. Risk of MN was significantly increased after surgery plus chemotherapy (HR, 6.8; 95% CI, 1.3 to 36.1) or after all modalities (surgery, chemotherapy, and radiation; HR, 7.6; 95% CI, 1.6 to 35.8), compared with no treatment with chemotherapy. MN rates per 1,000 person-years were 0.16 (surgery), 0.43 (plus radiation), 0.46 (plus chemotherapy), and 0.54 (all three modalities). Cumulative incidence of MN doubled between years 5 and 10 (0.24% to 0.48%); 9% of patients were alive at 10 years. Conclusion In this large early-stage breast cancer cohort, MN risk after radiation and/or adjuvant chemotherapy was low but higher than previously described. Risk continued to increase beyond 5 years. Individual risk of MN must be balanced against the absolute survival benefit of adjuvant chemotherapy. PMID

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

    We examined the roles of teaching hospitals, insurance status, and race/ ethnicity in women's receipt of adjuvant therapy for regional-stage breast cancer. Data were taken from the Florida Cancer Data System for cases diagnosed from July 1997 to December 2000. We evaluated the impact of health insurance status and hospital type on use of adjuvant therapy (after adjustment for age, race/ethnicity, and marital status). Interaction terms for hospital type, insurance status, and race/ethnicity were entered in each model. Teaching facilities diagnosed 12.5% of the cases; however, they cared for a disproportionate percentage (21.3%) of uninsured and Medicaid-insured women. Among women who received adjuvant chemotherapy only, those diagnosed in teaching hospitals were more likely than those diagnosed in nonteaching hospitals to receive therapy regardless of insurance status or race/ethnicity. Among women who received chemotherapy with or without hormonal therapy, Hispanics were more likely than White non-Hispanic women to receive therapy, whereas women with private insurance or Medicare were less likely than uninsured and Medicaid-insured women to receive this type of therapy. Teaching facilities play an important role in the diagnosis and treatment of regional-stage breast cancer among Hispanics, uninsured women, and women insured by Medicaid.

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

    ABSTRACT Objective: To evaluate the use of hyperbaric oxygen therapy as an adjunctive treatment in mediastinitis after coronary artery bypass surgery. Methods: This is a retrospective descriptive study, performed between October 2010 and February 2012. Hyperbaric oxygen therapy was indicated in difficult clinical management cases despite antibiotic therapy. Results: We identified 18 patients with mediastinitis during the study period. Thirty three microorganisms were isolated, and polymicrobial infection was present in 11 cases. Enterobacteriaceae were the most prevalent pathogens and six were multi-resistant agents. There was only 1 hospital death, 7 months after the oxygen therapy caused by sepsis, unrelated to hyperbaric oxygen therapy. This treatment was well-tolerated. Conclusion: The initial data showed favorable clinical outcomes. PMID:24136762

    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.

    Clinical surveys show a continuous increase of antimicrobial resistance related to the frequency of the administrated medication. The antimicrobial photodynamic therapy (aPDT) is an effective adjuvant to reduce the need of antibiotics in dentistry, especially in periodontics. The antimicrobial effect of lightactivated photosensitizers in periodontics is demonstrated in clinical studies and case reports. Indocyanine green (ICG) as a new adjuvant shows the high potential of antiphlogistic and antimicrobial effects in combination with laser-light activation. In trying to answer the question of just how far the influence of temperature is acting on bacteria, this study was carried out. The influences of ICG at different concentrations (0.01 up to 1 mg/ml) in combination with a culture medium (brain-heart-infusion) and a bacteria culture (Streptococcus salivarius) at different optical densities (OD600 0.5 and 0.1) were investigated under laser-light activation. Laser activation was carried out with diode laser at 810 nm and two different power settings (100 mW/300 mW). The pulse repetition rate was 2 kHz. Taking account of the fiber diameter, distance and spot size on the sample surface, the applicated intensities were 6.2 and 18.7 W/cm2. Total irradiation time was 20 s for all meaurements. Transmitted laser power and temperature increase in the culture medium as well as in the bacteria culture were determined. Additionally the influence of ICG regarding bacterial growth and bactericidal effect was investigated in the bacteria culture without laser irradiation. Without laser, no bactericidal effect of ICG was observed. Only a bacteriostatic effect could be proved. In dependence of the ICG concentration and the applied intensities a temperature increase of ΔT up to 80°C was measured.

    To evaluate variations in the use of adjuvant endocrine therapy (AET) by race and geography, this research examined their influence on initiation and adherence to AET in female Medicare enrollees with breast cancer, diagnosed between 2007 and 2011.Using SEER (Surveillance, Epidemiology, and End Results Program)-Medicare data from 2007 to 2001, logistic regressions with random intercept for county of residence were used to predict AET initiation during 1st year and AET adherence assessed by the medication possession ratio (MPR) during year after initiation in a sample of fee-for-service medicare beneficiaries. Part D enrollment was required for the examination of adherence. Independent variables examined were race (black, white, or other) and geographical indicators (area deprivation, non-metropolitan status, and physician shortage).Overall, 23% of patients did not initiate AET within 1 year and 26% of the initiation sample was not adherent to AET, with average follow-up time among initiators of 141 days and an average MPR of 0.84. Significant heterogeneity (P adherence varied from 77% in New Jersey to 68% in Utah.Blacks had lower initiation, enrollees not in Medicaid had lower adherence, lower area deprivation counties had lower initiation, earlier SEER-Medicare years had both later initiation and nonadherence, and significant (P adherence for blacks in youngest age group, with stage III tumors, tamoxifen use and blacks/others in oldest age group.Black women and women living in states with more rurality in the United States were less likely to receive guideline-recommended AET, which necessitates future efforts to alleviate these disparities to improve AET use and ultimately pursue more survival gains through optimizing adjuvant treatment use among cancer survivors.

    In order to observe the nutrition state in the severe multiple trauma patients undergoing adjuvant recombinant human growth hormone (rhGH) nutritional support therapy, 45 patients with severe multiple traumas (ISS>25) were randomly divided into 3 groups. All the 3 groups had been supplied with nitrogen and caloricity according to the need of patients for 16 days. The rhGH therapy started 48 h after surgery and lasted for 14 days in two rhGH-treated groups in which rhGH was 0.2 and 0.4 U/(kg·d) respectively, and the resting group served as control one. The levels of nitrogen balance, prealbumin and safety variables (blood sugar, Na+, TT3 and TT4) were observed and compared among the three groups. The levels of nitrogen balance on the postoperative day (POD) 3 and 5 in the rhGH-treated groups were - 1.28±3.19, 5.45±2.00 and -0.18±2.55, 6.11±1.60, respectively,which were significantly higher than those in the control group (-5.17±1.68 and -1.08±3.31, P<0.01). The values of prealbumin on the POD 3 and 5 in the rhGH-treated groups were 180.19±27.15, 194.44±50.82 and 194.94±29.65, 194.11±16.17, respectively, which were significantly higher than those in the control group (117.42±19.10 and 135.63±28.31, P<0.01). There was no significant difference between the rhGH 0.2 U/(kg·d) group and rhGH 0.4 U/(kg·d) group in both of the levels of nitrogen balance and prealbumin. It is concluded that the nutritional support therapy with adjuvant rhGH which starts 48 h after surgery improves the nutrition state of the patients with severe multiple trauma. It is safe for severe multiple trauma patients who accept rhGH at the dose of 0.2 and 0.4 U/(kg·d).

    Endometrial cancer is the most common gynaecological cancer in western countries. Radiotherapy remains the mainstay of postoperative management, but accumulating data show that adjuvant chemotherapy may display promising results after staging surgery. The prognosis of patients with metastatic disease remains disappointing with only one-year survival. Progestins represent an effective option, especially for those patients with low-grade estrogen and/or progesterone receptor positive disease. Chemotherapy using the combination of paclitaxel, doxorubicin, and cisplatin is beneficial for patients with advanced or metastatic disease after staging surgery and potentially for patients with early-stage disease and high-risk factors. Toxicity is a point in question; however, the combination of paclitaxel with carboplatin may diminish these concerns. In women with multiple medical comorbidities, single-agent chemotherapy may be better tolerated with acceptable results. Our increased knowledge of the molecular aspects of endometrial cancer biology has paved the way for clinical research to develop novel targeted antineoplastic agents (everolimus, temsirolimus, gefitinib, erlotinib, cetuximab, trastuzumab, bevacizumab, sorafenib) as more effective and less toxic options. Continued investigation into the molecular pathways of endometrial cancer development and progression will increase our knowledge of this disease leading to the discovery of novel, superior agents.

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

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

    To study the impact of postoperative radiation therapy (PORT) on survival in the Adjuvant Navelbine International Trialist Association (ANITA) randomized study of adjuvant chemotherapy. ANITA is a randomized trial of adjuvant cisplatin and vinorelbine chemotherapy vs. observation in completely resected non-small-cell lung carcinoma (NSCLC) Stages IB to IIIA. Use of PORT was recommended for pN+ disease but was not randomized or mandatory. Each center decided whether to use PORT before initiation of the study. We describe here the survival of patients with and without PORT within each treatment group of ANITA. No statistical comparison of survival was performed because this was an unplanned subgroup analysis. Overall, 232 of 840 patients received PORT (33.3% in the observation arm and 21.6% in the chemotherapy arm). In univariate analysis, PORT had a deleterious effect on the overall population survival. Patients with pN1 disease had an improved survival from PORT in the observation arm (median survival [MS] 25.9 vs. 50.2 months), whereas PORT had a detrimental effect in the chemotherapy group (MS 93.6 months and 46.6 months). In contrast, survival was improved in patients with pN2 disease who received PORT, both in the chemotherapy (MS 23.8 vs. 47.4 months) and observation arm (median 12.7 vs. 22.7 months). This retrospective evaluation suggests a positive effect of PORT in pN2 disease and a negative effect on pN1 disease when patients received adjuvant chemotherapy. The results support further evaluation of PORT in prospectively randomized studies in completely resected pN2 NSCLC.

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

    To evaluate the treatment outcomes and toxicity in endometrial cancer patients treated with hysterectomy and adjuvant intensity-modulated radiation therapy (IMRT) or conventional radiotherapy (CRT). There were 101 patients with stage IA-IIIC2 endometrial carcinoma treated with hysterectomy and adjuvant radiotherapy. In total, 36 patients received adjuvant CRT and 65 were treated with adjuvant IMRT. The endpoints were overall survival, local failure-free survival, and disease-free survival. Patients were assessed for acute toxicity weekly according to the Common Terminology Criteria for Adverse Events version 3.0. Late toxicity was evaluated according to the Radiation Therapy Oncology Group and the European Organization for Research and Treatment of Cancer Late Radiation Morbidity Scoring Schema. The 5-year overall survival, local failure-free survival, and disease-free survival for the CRT group and the IMRT group were 82.9% versus 93.5% (p = 0.26), 93.7% versus 89.3% (p = 0.68), and 88.0% versus 82.8% (p = 0.83), respectively. Four (11.1%) patients had Grade 3 or greater acute gastrointestinal (GI) toxicity and three (8.3%) patients had Grade 3 or greater acute genitourinary (GU) toxicity in the CRT group, whereas four (6.2%) patients had Grade 3 or greater acute GI toxicity in the IMRT group and no patient had severe GU toxicity. There was one (2.8%) patient who had Grade 3 or greater late GI toxicity and one (2.8%) patient had Grade 3 or greater late GU toxicity in the CRT group, whereas no patient had severe GI or GU toxicity in the IMRT group. Adjuvant IMRT for endometrial cancer patients had comparable clinical outcomes with CRT and had less acute and late toxicity. Copyright © 2013. Published by Elsevier B.V.

    Full Text Available Abstract Purpose To assess whether an expanded (five level risk stratification system can be used to identify the sub-group of intermediate risk patients with prostate cancer who benefit from combining androgen deprivation therapy (ADT with external beam radiotherapy (EBRT. Materials and methods Using a previously validated 5-risk group schema, a prospective non-randomized data set of 1423 men treated at the British Columbia Cancer Agency was assessed for the primary end point of biochemical control (bNED with the RTOG-ASTRO "Phoenix" definition (lowest PSA to date + 2 ng/mL, both with and without adjuvant ADT. The median follow-up was 5 years. Results There was no bNED benefit for ADT in the low or low intermediate groups but there was a statistically significant bNED benefit in the high intermediate, high and extreme risk groups. The 5-year bNED rates with and without ADT were 70% and 73% respectively for the low intermediate group (p = non-significant and 72% and 58% respectively for the high intermediate group (p = 0.002. Conclusion There appears to be no advantage to ADT where the Gleason score is 6 or less and PSA is 15 or less. ADT is beneficial in patients treated to standard dose radiation with Gleason 6 disease and a PSA greater than 15 or where the Gleason score is 7 or higher.

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

  13. How plausible is the use of dietary n-3 PUFA in the adjuvant therapy of cancer?

    Considerable debate exists regarding the potential antineoplastic effect of dietary long-chain n-3 PUFA contained in fatty fishes. Since the majority of published data has proven that their intake does not induce toxic or carcinogenic effects in humans, their possible preventive use against cancer has been suggested. On the other hand, it is unlikely that they could be effective in cancer patients as a single therapy. Nevertheless, a considerable effort has been put forth in recent years to evaluate the hypothesis that n-3 PUFA might improve the antineoplastic efficiency of currently used anticancer agents. The rationale for this therapeutic combinatory strategy is trying to increase cancer sensitivity to conventional therapies. This could allow the use of lower drug/radiation doses and, thereby, a reduction in the detrimental health effects associated with these treatments. We will here critically examine the studies that have investigated this possibility, by focusing particularly on the biological and molecular mechanisms underlying the antineoplastic effect of these combined treatments. A possible use of n-3 PUFA in combination with the innovative single-targeted anti-cancer therapies, that often are not completely devoid of dangerous side-effects, is also suggested.

    Objective:To analyze the effect of folic acid adjuvant therapy on Hcy as well as lipid metabolism and endothelial injury in coronary heart disease patients with stable angina pectoris. Methods:A total of 98 cases of coronary heart disease patients with stable angina pectoris who received treatment in our hospital from March 2014 to August 2015 were selected as research subjects and randomly divided into observation group 49 cases and control group 49 cases. Control group received conventional clinical treatment, observation group received folic acid adjuvant therapy, and then differences in levels of Hcy, lipid metabolism, endothelial injury and adhesion molecules were compared between two groups after treatment. Results:Hcy, TC, LDL-C and ApoB values of observation group were lower than those of control group while HDL-C and ApoA1/ApoB values were higher than those of control group;Flow-vel and FMD values of observation group after treatment were higher than those of control group;serum E-selectin, ICAM-1, VCAM-1 and sICAM-1 values of observation group after treatment were lower than those of control group. Conclusion:Folic acid adjuvant therapy for coronary heart disease patients with stable angina pectoris can reduce plasma Hcy level and optimize lipid metabolism, further protects vascular endothelium, and has positive clinical significance.

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

    Gastric cancer remains one of the most common malignancies worldwide. Despite the significant advances in surgical treatment and multimodality strategies, prognosis has modestly improved over the last two decades. Locoregional relapse remains one of the main issues and the combined chemoradiation treatment seems to be one of the preferred approaches. However, more than ten years after the hallmark INT-0116 trial, minimal progress has been made both in terms of effectiveness and toxicity. Moreover, new regimens added to combined therapy failed to prove favourable results. Herein, we attempt a thorough literature review comparing pros and cons of all relative studies and potential bias, targeting well-designed future approaches. PMID:26101524

    OBJECTIVE Primary osteosarcoma of the spine is a rare osseous neoplasm. While previously reported retrospective studies have demonstrated that overall patient survival is impacted mostly by en bloc resection and chemotherapy, the continued management of residual disease remains to be elucidated. This systematic review was designed to address the role of revision surgery and multimodal adjuvant therapy in cases in which en bloc excision is not initially achieved. METHODS A systematic literature search spanning the years 1966 to 2015 was performed on PubMed, Medline, EMBASE, and Web of Science to identify reports describing outcomes of patients who underwent biopsy alone, neurological decompression, or intralesional resection for osteosarcoma of the spine. Studies were reviewed qualitatively, and the clinical course of individual patients was aggregated for quantitative meta-analysis. RESULTS A total of 16 studies were identified for inclusion in the systematic review, of which 8 case reports were summarized qualitatively. These studies strongly support the role of chemotherapy for overall survival and moderately support adjuvant radiation therapy for local control. The meta-analysis revealed a statistically significant benefit in overall survival for performing revision tumor debulking (p = 0.01) and also for chemotherapy at relapse (p osteosarcoma of the spine is neoadjuvant chemotherapy followed by en bloc marginal resection, this objective is not always achievable given anatomical constraints and other limitations at the time of initial clinical presentation. This systematic review supports the continued aggressive use of revision surgery and multimodal adjuvant therapy when possible to improve outcomes in patients who initially undergo subtotal debulking of osteosarcoma. A limitation of this systematic review is that lesions amenable to subsequent resection or tumors inherently more sensitive to adjuvants would exaggerate a therapeutic effect of these

    In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence. Remaining concerns pertain to the choice of the optimal therapy regimen, strict patient selection by accurate pre-operative staging, standardization of surgical procedures, and valid criteria for response evaluation. New well-designed trials will be necessary to find the best therapeutic approach in pre-operative settings and the best way to combine old-generation chemotherapeutic drugs with new-generation molecules.

  1. Is there room for improvement in the emollients for adjuvant therapy?

    Science.gov (United States)

    Trapp, M

    2007-09-01

    Emollients play an important part in the management of patients with dry skin disorders, such as atopy, allergy, eczema, psoriasis or dryness following chemotherapy or radiotherapy. Their use in the treatment of diseased and sensitive skin requires not only an efficient hydrating and lipid-replenishing effect on the skin, but minimal risk for skin irritation or sensitization. This will be influenced by their formulation and number and type of ingredients and, due to the nature of their application, requires clinical testing to ensure their appropriateness for dermatological rather than cosmetic use. A new generation of emollients has been developed for the care of dry, or very dry, and sensitive skin. Among these, Dardia Lipo Line (Intendis GmbH, Berlin, Germany) has been formulated specifically for use in post-therapy preventive skin care. The current clinical evidence for this line of emollients is reviewed here.

    ABSTRACT Objectives This study evaluated the antimicrobial efficacy of ozone therapy in teeth contaminated with Pseudomonas aeruginosa, Enterococcus faecalis, and Staphylococcus aureus using a mono-species biofilm model. Parallel to this, the study aimed to evaluate the cytotoxicity of ozone for human gingival fibroblasts. Material and Methods: One hundred and eighty single-root teeth were contaminated with a mono-species biofilm of Enterococcus faecalis, Pseudomonas aeruginosa, and Staphylococcus aureus. Groups were formed: Group I – control; Group II – standard protocol; Group III – standard protocol + ozone gas at 40 µg/mL; and Group IV – standard protocol + aqueous ozone at 8 µg/mL. In parallel, human gingival fibroblasts were submitted to the MTT test. Cells were plated, then ozone was applied as follows: Group I (control) – broth medium; Group II – aqueous ozone at 2 µg/mL; Group III – aqueous ozone at 5 µg/mL; and Group IV – aqueous ozone at 8 µg/mL. Data were submitted to the Kruskal Wallis test and Bonferroni post hoc analyses to assess microbiology and cytotoxicity, respectively (p<0.05%). Results The results revealed antimicrobial efficacy by Group IV with no CFU count. The cytotoxicity assay showed Groups III and IV to be the most aggressive, providing a decrease in cell viability at hour 0 from 100% to 77.3% and 68.6%, respectively. Such a decrease in cell viability was reverted, and after 72 hours Groups III and IV provided the greatest increase in cell viability, being statistically different from Groups I and II. Conclusion According to the applied methodology and the limitations of this study, it was possible to conclude that ozone therapy improved the decontamination of the root canal ex vivo. Ozone was toxic to the cells on first contact, but cell viability was recovered. Thus, these findings suggest that ozone might be useful to improve root canal results. PMID:28076466

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

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

Thus, while we are only beginning to understand the pluripotent mechanisms through which the KD affects tumor growth and response to conventional therapies, the emerging data provide strong support for the use of a KD in the treatment of malignant gliomas. This has led to a limited number of clinical trials investigating the use of a KD in patients with primary and recurrent glioma. PMID:27899882

    Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder arising from synovial cells of the tendon sheets and joint capsules. The potential value of external beam radiation therapy in the interdisciplinary management of PVNS is demonstrated by a comprehensive literature review on the clinical use of radiotherapy and the results of national patterns of care study (PCS) which was conducted by the German Cooperative Group on Radiotherapy in Benign Diseases (GCG-BD) in 2008-2009. A structured questionnaire was mailed to all 227 RT institutions in Germany to assess all previous treatments, the RT indication and techniques, the rate of local control, the functional outcome and the possible adverse effects related to the use of external beam radiation therapy (RT). For comparison of the clinical outcome data, a systematic literature research in several international electronic databases and a conventional library search were performed to identify publications addressing the use of RT for PVNS. Based on an overall response rate of 83.2%, the PCS was nationally representative. Ten percent of institutions presented clinical experience with the use of RT for PVNS; from this database a total of 41 treated sites from 14 institutions were evaluable for long-term analysis. The primary therapeutic approach was cytoreductive surgery in all cases. In cases of residual tissue or complete resection of extensive local recurrences, RT was applied in 39 cases (95.1%). An excellent or good functional outcome was noted in 34 cases (82.9%). The use of RT was not associated with early or late toxicity larger than RTOG grade II. The literature review identified 19 published studies (1940-2009) which represented a total of 140 cases or patients, respectively. After follow-up periods ranging from 1-250 months and administration of total doses in the range of 16-50 Gy the overall rate of local control was 84.5%.

    Glioblastoma multiforme (GBM) is a CNS (central nervous system) malignancy with a low cure rate. Median time to progression after standard treatment is 7 months and median overall survival is 15 months [1]. Post-treatment vasculogenesis promoted by recruitment of bone marrow derived cells (BMDCs, CD11b+ myelomonocytes) is one of main mechanisms of GBM resistance to initial chemoradiotherapy treatment [2]. Local secretion of SDF-1, cognate ligand of BMDCs CXCR4 receptors attracts BMDCs to the post-radiation tumor site.[3]. This SDF-1 hypoxia-dependent effect can be blocked by AMD3100 (plerixafor) [4]. We report a GBM case treated after chemo- radiotherapy with plerixafor and a combination of an mTOR, a Sirt1 and an EGFRvIII inhibitor. After one year temozolomide and the EGFRvIII inhibitor were stopped. Plerixafor, and the MTOR and Sirt-1 inhibitors were continued. He is in clinical and radiologic remission 30 months from the initiation of his adjuvant treatment. To our knowledge, this is the first report of a patient treated for over two years with a CXCR4 inhibitor (plerixafor), as part of his adjuvant treatment. We believe there is sufficient experimental evidence to consider AMD3100 (plerixafor) part of the adjuvant treatment of GBM. Significance The adjuvant inhibition of GBM vasculogenesis(a process different from local angiogenesis) by specifically blocking the migration of BMDCs to the primary tumor site with inhibitors of the CXCR4/SDF-1 axis represents a potential novel therapeutic approach to GBM. There is significant pre-clinical evidence and validation for its use as demonstrated in a patient derived tumor xenograft model of GBM. Together with other specific anti-tumoral therapies, the active inhibition of vasculogenesis in the adjuvant treatment of GBM is deserving of further exploration. PMID:27489862

    AIM: To determine the efficacy and success of percutaneous aspiration irrigation and reaspiration (PAIR) in the management of hepatic hydatidosis.METHODS: Twenty-six patients with 32 hepatic hydatid cysts had PAIR. Twenty-two patients received at least 2 wk of drug therapy before the procedure was carried out to reduce the risk of recurrence from spillage during the procedure. The procedure was performed under local anesthesia with a 19-gauge 20 cm long needle,the cyst was punctured, cystic content (approximately 30 mL) was aspirated by a 12-14 F pigtail catheter and aspirated fluids were sent for analysis. Once the cyst was almost empty, two-thirds of the net amount of ma materialaspirated was replaced by hypertonic saline and left in the cavity for about 30 min, with the catheter left in place for reaspiration of most of the fluid. When the amount of fluid drained was less than 10 mL per 24 h,the drainage catheter was removed.RESULTS: All 32 cysts showed evidence of immediate collapse after completion of the procedure, and before discharge from hospital, ultrasound examination showed fluid reaccumulation in all cysts. Serial follow-up showed a progressive decrease in the size and change in the appearance of cysts. To confirm the sterility of these cystic cavities, seven cysts were reaspirated on average 3 mo after the procedure. Investigations revealed no viable scolices.CONCLUSION: PAIR using hypertonic saline is very effective and safe with proper precautions.

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

    TNF-Related Apoptosis-Inducing Ligand (TRAIL) is a well-known apoptosis inducer, which activates the extrinsic death pathway. TRAIL is pro-apoptotic on colon cancer cells, while not cytotoxic towards normal healthy cells. However, its clinical use is limited by cell resistance to cell death which occurs in approximately 50% of cancer cells. Short Chain Fatty Acids (SCFA) are also known to specifically induce apoptosis of cancer cells. In accordance, we have shown that food grade dairy propionibacteria induce intrinsic apoptosis of colon cancer cells, via the production and release of SCFA (propionate and acetate) acting on mitochondria. Here, we investigated possible synergistic effect between Propionibacterium freudenreichii and TRAIL. Indeed, we hypothesized that acting on both extrinsic and intrinsic death pathways may exert a synergistic pro-apoptotic effect. Whole transcriptomic analysis demonstrated that propionibacterial supernatant or propionibacterial metabolites (propionate and acetate), in combination with TRAIL, increased pro-apoptotic gene expression (TRAIL-R2/DR5) and decreased anti-apoptotic gene expression (FLIP, XIAP) in HT29 human colon cancer cells. The revealed synergistic pro-apoptotic effect, depending on both death receptors (TRAIL-R1/DR4, TRAIL-R2/DR5) and caspases (caspase-8, -9 and -3) activation, was lethal on cancer cells but not on normal human intestinal epithelial cells (HIEC), and was inhibited by Bcl-2 expression. Finally, milk fermented by P. freudenreichii induced HT29 cells apoptosis and enhanced TRAIL cytotoxic activity, as did P. freudenreichii DMEM culture supernatants or its SCFA metabolites. These results open new perspectives for food grade P. freudenreichii-containing products in order to potentiate TRAIL-based cancer therapy in colorectal cancer.

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

    The addition of bevacizumab to chemotherapy improves progression-free survival in metastatic breast cancer and pathological complete response rates in the neoadjuvant setting. Micrometastases are dependent on angiogenesis, suggesting that patients might benefit from anti-angiogenic strategies in the adjuvant setting. We therefore assessed the addition of bevacizumab to chemotherapy in the adjuvant setting for women with triple-negative breast cancer. For this open-label, randomised phase 3 trial we recruited patients with centrally confirmed triple-negative operable primary invasive breast cancer from 360 sites in 37 countries. We randomly allocated patients aged 18 years or older (1:1 with block randomisation; stratified by nodal status, chemotherapy [with an anthracycline, taxane, or both], hormone receptor status [negative vs low], and type of surgery) to receive a minimum of four cycles of chemotherapy either alone or with bevacizumab (equivalent of 5 mg/kg every week for 1 year). The primary endpoint was invasive disease-free survival (IDFS). Efficacy analyses were based on the intention-to-treat population, safety analyses were done on all patients who received at least one dose of study drug, and plasma biomarker analyses were done on all treated patients consenting to biomarker analyses and providing a measurable baseline plasma sample. This trial is registered with ClinicalTrials.gov, number NCT00528567. Between Dec 3, 2007, and March 8, 2010, we randomly assigned 1290 patients to receive chemotherapy alone and 1301 to receive bevacizumab plus chemotherapy. Most patients received anthracycline-containing therapy; 1638 (63%) of the 2591 patients had node-negative disease. At the time of analysis of IDFS, median follow-up was 31·5 months (IQR 25·6-36·8) in the chemotherapy-alone group and 32·0 months (27·5-36·9) in the bevacizumab group. At the time of the primary analysis, IDFS events had been reported in 205 patients (16%) in the chemotherapy

    We analyzed the expression levels of fluoropyrimidine-metabolizing enzymes (thymidylate synthase [TS], dihydropyrimidine dehydrogenase [DPD], thymidine phosphorylase [TP] and orotate phosphoribosyltransferase [OPRT]) to identify potential biomarkers related to treatment outcomes in gastric cancer (GC) patients receiving adjuvant S-1 chemotherapy. In this study, 184 patients who received curative gastrectomy (D2 lymph node dissection) and adjuvant S-1 were included. Immunohistochemistry and quantitative reverse transcription polymerase chain reaction were performed to measure the protein and mRNA levels of TS, DPD, TP, and OPRT in tumor tissue. In univariate analysis, low intratumoral DPD protein expression was related to poorer 5-year disease-free survival (DFS; 78% vs. 88%; P = 0.068). Low intratumoral DPD mRNA expression (1st [lowest] quartile) was also related to poorer DFS (69% vs. 90%; P DPD expression (2nd to 4th quartiles). In multivariate analyses, low intratumoral DPD protein or mRNA expression was related to worse DFS (P DPD mRNA expression (29% vs. 16%; P = 0.068). In conclusion, GC patients with high intratumoral DPD expression did not have inferior outcome following adjuvant S-1 therapy compared with those with low DPD expression. Instead, low intratumoral DPD expression was related to poor DFS.

    In recent years, breast cancer has witnessed some notable improvements regarding early diagnosis and new therapeutical strategies, mainly because of the utilization of new drugs and systemic treatment protocols, which have had a direct impact in the increase of these patients' global survival rate. At the same time, it is an ever-growing concern among oncology professionals to identify and minimize as much as possible the effects of long-term toxicity resulting from cancer therapies. Within this context, physiotherapy fits as a preventive and rehabilitating factor regarding functional and skeletal alterations, deriving not only from the direct action of breast cancer, but also from the treatment to which these patients are submitted. The aim of this study was to revise the scientific literature on possible adjuvant chemotherapy-induced secondary deleterious effects on the bone mass of patients diagnosed with breast cancer, and also to revise the literature on the intervention of physiotherapy in cases of secondary bone mass loss caused by adjuvant chemotherapy in patients suffering from breast cancer. The research was carried out by consulting the following medical websites: Medicus Medline Index, Lilacs, Sciello, PubMed (National Library of Medicine), Google Academic and Capes (a Brazilian website for scientific information). The selection gathers articles written in different languages, English in special, published from January 1998 to October 2008. 24 studies explicitly mention chemotherapy-induced direct and/or indirect effects upon bone mass. Different authors refer to bone mass loss as one possible secondary deleterious effect resulting from adjuvant chemotherapy applied in breast cancer treatment. Nonetheless, no scientific articles were found on the subject of physiotherapy intervention aimed at patients in this specific condition. The results achieved in this revision study point out the possible chemotherapy-induced late deleterious effects on patients

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

Patients were randomized to Betahistine dihydrochloride plus basic CHF therapy or only basic therapy groups. Enalapril dose titration was performed in all patients. Quality of life and giddiness severity evaluation, electrocardiogram was performed initially and after treatment. Clinical examination results, drug therapy and adverse event were registered at each visit.Results. The target ACE inhibitor dose (≥20 mg daily was reached in 97 % of patients. It led to significant reduction of dyspnea, edemas, CHF class reduction and life quality increase. Significant differences between investigated groups were not found. Reduction of giddiness severity was shown in both groups. There was a trend to more prominent improvement of life quality (р=0,08 and more frequent achievement of target ACE inhibitor dose in patients treated with betahistine dihydrochloride.Conclusion. The target ACE inhibitor dose can be achieved more than in 90% of patients with CHF class II-III without hypotension symptoms. Adjuvant usage of betahistine dihydrochloride is necessary in patients with CHF still suffering from giddiness after achievement of target ACE inhibitor dose.

    Purpose: To assess the locoregional failure in patients with Stage I-II breast cancer treated with radical mastectomy and to evaluate whether a subset of these patients might be at sufficiently high risk of locoregional recurrence (LRR) to benefit from postmastectomy irradiation (PMRT). Methods and Materials: Stage I-II breast cancer patients (n = 150) treated with radical mastectomy without adjuvant irradiation between 1999 and 2005 were analyzed. The pattern of LRR was reported. Kaplan-Meier analysis was used to calculate rates of LRR, and Cox proportional hazards methods were used to evaluate potential risk factors. Results: Median follow-up was 75 months. Mean patient age was 56 years. One-hundred forty-three (95%) patients received adjuvant systemic therapy: 85 (57%) hormonal therapy alone, 14 (9%) chemotherapy alone, and 44 (29%) both chemotherapy and hormonal therapy. Statistically significant factors associated with increased risk of LRR were premenopausal status (p = 0.004), estrogen receptor negative cancer (p = 0.02), pathologic grade 3 (p = 0.02), and lymphovascular invasion (p = 0.001). T and N stage were not associated with increased risk of regional recurrence. The 5-year LRR rate for patients with zero or one, two, three, and four risk factors was 1%, 10.3%, 24.2%, and 75%, respectively. Conclusions: A subset of patients with early-stage breast cancer is at high risk of LRR, and therefore PMRT might be beneficial.

    The treatment for most patients with early-stage cervical cancer involves radical hysterectomy and pelvic lymph node dissection, and indications for postoperative adjuvant therapy have been determined by evaluating the prognostic risk factors for recurrence in each case. The aim of this review is to raise and discuss the various issues that have not yet been resolved regarding the prognostic risk factors and postoperative adjuvant therapy. Several clinicopathological factors, such as tumor size, lymphovascular space involvement, deep stromal invasion, parametrial involvement and lymph node metastasis, have been identified to have prognostic significance in early-stage cervical cancer. However, this remains controversial because there is suggested to be substantial heterogeneity among patients after radical hysterectomy and lymphadenectomy and it would be difficult to define the risk groups clearly. This indicates the need to develop more convenient and accurate criteria to define risk groups. According to the currently available evidence, patients in the high-risk group should receive adjuvant concurrent chemoradiotherapy (CCRT) with cisplatin (CDDP) and fluolouracil. However, CCRT with CDDP administered weekly (CCRT-P) has instead been applied in a clinical context worldwide. Whether CCRT-P has a survival benefit compared with radiotherapy (RT) alone is unknown because no randomized phase III trials have been performed for patients in the high-risk group after radical surgery. Patients with high-risk factors have a high incidence of distant metastasis, for whom systemic chemotherapy might be a key to improving overall survival. The pivotal study that investigated the role of RT alone for patients with intermediate-risk factors after hysterectomy is the GOG092 trial. This trial showed a 47% reduction in the risk of recurrence after RT compared with no further treatment (NFT). However, the improvement in overall survival with RT did not reach statistical

    For breast cancer, guidelines direct the delivery of adjuvant systemic therapy on the basis of lymph node status, histology, tumor size, grade, and hormonal receptor status. We explored how race/ethnicity, insurance, census tract-level poverty and education, and hospital Commission on Cancer (CoC) status were associated with the receipt of guideline-concordant adjuvant systemic therapy. Locoregional breast cancers diagnosed in 2004 (n = 6,734) were from the National Program of Cancer Registries-funded seven-state Patterns of Care study of the Centers for Disease Control and Prevention. Predictors of guideline-concordant (receiving/not receiving) adjuvant systemic therapy, according to National Comprehensive Cancer Network Guidelines, were explored by logistic regression. Overall, 35% of women received nonguideline chemotherapy, 12% received nonguideline regimens, and 20% received nonguideline hormonal therapy. Significant predictors of nonguideline chemotherapy included Medicaid insurance (odds ratio [OR], 0.66; 95% CI, 0.50 to 0.86), high-poverty areas (OR, 0.77; 95% CI, 0.62 to 0.96), and treatment at non-CoC hospitals (OR, 0.69; 95% CI, 0.56 to 0.85), with adjustment for age, registry, and clinical variables. Predictors of nonguideline regimens among chemotherapy recipients included lack of insurance (OR, 0.47; 95% CI, 0.25 to 0.92), high-poverty areas (OR, 0.71; 95% CI, 0.51 to 0.97), and low-education areas (OR, 0.65; 95% CI, 0.48 to 0.89) after adjustment. Living in high-poverty areas (OR, 0.78; 95% CI, 0.64 to 0.96) and treatment at non-CoC hospitals (OR, 0.68; 95% CI, 0.55 to 0.83) predicted nonguideline hormonal therapy after adjustment. ORs for poverty, education, and insurance were attenuated in the full models. Sociodemographic and hospital factors are associated with guideline-concordant use of systemic therapy for breast cancer. The identification of modifiable factors that lead to nonguideline treatment may reduce disparities in breast cancer

    Full Text Available PURPOSE: Despite the benefits of estrogen receptor (ER-targeted endocrine therapies in breast cancer, many tumors develop resistance. MicroRNAs (miRNAs have been suggested as promising biomarkers and we here evaluated whether a miRNA profile could be identified, sub-grouping ER+ breast cancer patients treated with adjuvant Tamoxifen with regards to probability of recurrence. EXPERIMENTAL DESIGN: Global miRNA analysis was performed on 152 ER+ primary tumors from high-risk breast cancer patients with an initial discovery set of 52 patients, followed by two independent test sets (N = 60 and N = 40. All patients had received adjuvant Tamoxifen as mono-therapy (median clinical follow-up: 4.6 years and half had developed distant recurrence (median time-to-recurrence: 3.5 years. MiRNA expression was examined by unsupervised hierarchical clustering and supervised analysis, including clinical parameters as co-variables. RESULTS: The discovery set identified 10 highly significant miRNAs that discriminated between the patient samples according to outcome. However, the subsequent two independent test sets did not confirm the predictive potential of these miRNAs. A significant correlation was identified between miR-7 and the tumor grade. Investigation of the microRNAs with the most variable expression between patients in different runs yielded a list of 31 microRNAs, eight of which are associated with stem cell characteristics. CONCLUSIONS: Based on the large sample size, our data strongly suggests that there is no single miRNA profile predictive of outcome following adjuvant Tamoxifen treatment in a broad cohort of ER+ breast cancer patients. We identified a sub-group of Tamoxifen-treated breast cancer patients with miRNA-expressing tumors associated with cancer stem cell characteristics.

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

    Purpose To provide recommendations on appropriate use of breast tumor biomarker assay results to guide decisions on adjuvant systemic therapy for women with early-stage invasive breast cancer. Methods A literature search and prospectively defined study selection sought systematic reviews, meta-analyses, randomized controlled trials, prospective-retrospective studies, and prospective comparative observational studies published from 2006 through 2014. Outcomes of interest included overall survival and disease-free or recurrence-free survival. Expert panel members used informal consensus to develop evidence-based guideline recommendations. Results The literature search identified 50 relevant studies. One randomized clinical trial and 18 prospective-retrospective studies were found to have evaluated the clinical utility, as defined by the guideline, of specific biomarkers for guiding decisions on the need for adjuvant systemic therapy. No studies that met guideline criteria for clinical utility were found to guide choice of specific treatments or regimens. Recommendations In addition to estrogen and progesterone receptors and human epidermal growth factor receptor 2, the panel found sufficient evidence of clinical utility for the biomarker assays Oncotype DX, EndoPredict, PAM50, Breast Cancer Index, and urokinase plasminogen activator and plasminogen activator inhibitor type 1 in specific subgroups of breast cancer. No biomarker except for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 was found to guide choices of specific treatment regimens. Treatment decisions should also consider disease stage, comorbidities, and patient preferences. PMID:26858339

    Full Text Available Elevated Microsatellite Alterations at Selected Tetranucleotide repeats (EMAST is a genetic signature found in up to 60% of colorectal cancers (CRCs that is caused by somatic dysfunction of the DNA mismatch repair (MMR protein hMSH3. We have previously shown in vitro that recognition of 5-fluorouracil (5-FU within DNA and subsequent cytotoxicity was most effective when both hMutSα (hMSH2-hMSH6 heterodimer and hMutSβ (hMSH2-hMSH3 heterodimer MMR complexes were present, compared to hMutSα > hMutSβ alone. We tested if patients with EMAST CRCs (hMutSβ defective had diminished response to adjuvant 5-FU chemotherapy, paralleling in vitro findings. We analyzed 230 patients with stage II/III sporadic colorectal cancers for which we had 5-FU treatment and survival data. Archival DNA was analyzed for EMAST (>2 of 5 markers mutated among UT5037, D8S321, D9S242, D20S82, D20S85 tetranucleotide loci. Kaplan-Meier survival curves were generated and multivariate analysis was used to determine contribution to risk. We identified 102 (44% EMAST cancers. Ninety-four patients (41% received adjuvant 5-FU chemotherapy, and median follow-up for all patients was 51 months. Patients with EMAST CRCs demonstrated improved survival with adjuvant 5FU to the same extent as patients with non-EMAST CRCs (P<0.05. We observed no difference in survival between patients with stage II/III EMAST and non-EMAST cancers (P = 0.36. There is improved survival for stage II/III CRC patients after adjuvant 5-FU-based chemotherapy regardless of EMAST status. The loss of contribution of hMSH3 for 5-FU cytotoxicity may not adversely affect patient outcome, contrasting patients whose tumors completely lack DNA MMR function (MSI-H.

    Full Text Available We analyzed the expression levels of fluoropyrimidine-metabolizing enzymes (thymidylate synthase [TS], dihydropyrimidine dehydrogenase [DPD], thymidine phosphorylase [TP] and orotate phosphoribosyltransferase [OPRT] to identify potential biomarkers related to treatment outcomes in gastric cancer (GC patients receiving adjuvant S-1 chemotherapy. In this study, 184 patients who received curative gastrectomy (D2 lymph node dissection and adjuvant S-1 were included. Immunohistochemistry and quantitative reverse transcription polymerase chain reaction were performed to measure the protein and mRNA levels of TS, DPD, TP, and OPRT in tumor tissue. In univariate analysis, low intratumoral DPD protein expression was related to poorer 5-year disease-free survival (DFS; 78% vs. 88%; P = 0.068. Low intratumoral DPD mRNA expression (1st [lowest] quartile was also related to poorer DFS (69% vs. 90%; P < 0.001 compared to high intratumoral DPD expression (2nd to 4th quartiles. In multivariate analyses, low intratumoral DPD protein or mRNA expression was related to worse DFS (P < 0.05, irrespective of other clinical variables. TS, TP, and OPRT expression levels were not related to treatment outcomes. Severe non-hematologic toxicities (grade ≥ 3 had a trend towards more frequent development in patients with low intratumoral DPD mRNA expression (29% vs. 16%; P = 0.068. In conclusion, GC patients with high intratumoral DPD expression did not have inferior outcome following adjuvant S-1 therapy compared with those with low DPD expression. Instead, low intratumoral DPD expression was related to poor DFS.

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

    14 patients with transional-cell bladder cancer in stage T1N0M0G2 after transurethral bladder resection were offered adjuvant treatment with PDT. Adjuvant PDT was performed 1-1.5 months after transurethral bladder resection for superficial bladder cancer. Prior to PDT conventional and fluorescent cystoscopy were performed. In the absence of inflammation and after full epitalisation of postoperative wound a session of therapy was performed. 24 hours prior to PDT-session photosensitizer Photosens was injected intravenously in the dose of 0.8 mg per kg of body weight. Prior to PDT local anesthesia of urethra with lidocain-gel was performed. Cystoscopy was carried out. PDT was performed with diode laser "Biospec" (675 nm). During the session the place of standing diffuser and the volume of a bladder were controlled. After 7 months of observation no tumor recidivists were observed. Registered side effects were not life-threatened. 5 patients had pain or discomfort in suprapubic area, ceasing spontaneously or requiring administration of analgetics. No systemic side-effects or allergic reactions were observed. The method can be used in out-patient practice. Absence of early recidivists shows efficiency of PDT in the treatment of superficial bladder cancer. Further study is necessary to estimate optimal regimen of PDT. The further controlling of condition on the patients in this group is required. At the laboratory animals' experiment, we conducted the explorations devoted to the influence of the photodynamic effect at the prostate's tissues.

    Full Text Available BACKGROUND: The role of bisphosphonates (BP in early breast cancer (BC has been considered controversial. We performed a meta-analysis of all randomized controlled trials (RCTs that appraised the effects of BP on survival in early BC. METHODS: RCTs were identified by searching the Cochrane Library, MEDLINE databases and conference proceedings. Hazard ratios (HRs of overall survival (OS, disease-free survival (DFS and relative risks of adverse events were estimated and pooled. RESULTS: Thirteen trials met the inclusion criteria, evaluating a total of 15,762 patients. Meta-analysis of ten trials which reported OS revealed no statistically significant benefit in OS for BP (HR 0.89, 95% CI = 0.79 to 1.01. Meta-analysis of nine trials which reported the DFS revealed no benefit in DFS (HR 0.95 (0.81-1.12. Meta-analysis upon menopausal status showed a statistically significant better DFS in the BP-treated patients (HR 0.81(0.69-0.95. In meta-regression, chemotherapy was negatively associated with HR of survival. CONCLUSIONS: Our meta-analysis indicates a positive effect for adjuvant BP on survival only in postmenopausal patients. Meta-regression demonstrated a negative association between chemotherapy use BP effect on survival. Further large scale RCTs are warranted to unravel the specific subgroups that would benefit from the addition of BP in the adjuvant setting.

    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.

    Unanswered questions remain in determining which high-risk node-negative colon cancer (CC) cohorts benefit from adjuvant therapy and how it may differ in an equal access population. Machine-learned Bayesian Belief Networks (ml-BBNs) accurately estimate outcomes in CC, providing clinicians with Clinical Decision Support System (CDSS) tools to facilitate treatment planning. We evaluated ml-BBNs ability to estimate survival and recurrence in CC. We performed a retrospective analysis of registry data of patients with CC to train-test-crossvalidate ml-BBNs using the Department of Defense Automated Central Tumor Registry (January 1993 to December 2004). Cases with events or follow-up that passed quality control were stratified into 1-, 2-, 3-, and 5-year survival cohorts. ml-BBNs were trained using machine-learning algorithms and k-fold crossvalidation and receiver operating characteristic curve analysis used for validation. BBNs were comprised of 5301 patients and areas under the curve ranged from 0.85 to 0.90. Positive predictive values for recurrence and mortality ranged from 78 to 84 per cent and negative predictive values from 74 to 90 per cent by survival cohort. In the 12-month model alone, 1,132,462,080 unique rule sets allow physicians to predict individual recurrence/mortality estimates. Patients with Stage II (N0M0) CC benefit from chemotherapy at different rates. At one year, all patients older than 73 years of age with T2-4 tumors and abnormal carcinoembryonic antigen levels benefited, whereas at five years, all had relative reduction in mortality with the largest benefit amongst elderly, highest T-stage patients. ml-BBN can readily predict which high-risk patients benefit from adjuvant therapy. CDSS tools yield individualized, clinically relevant estimates of outcomes to assist clinicians in treatment planning.

    Objective:To study the effect of adjuvant ganglioside sodium therapy on nerve injury degree as well as cytokines and humoral immunity in patients with acute severe craniocerebral injury. Methods:94 patients with severe craniocerebral injury treated in our hospital between March 2013 and March 2016 were selected and randomly divided into the ganglioside sodium group (GM1 group) and control group. Before treatment as well as after 4 weeks and 8 weeks of treatment, serum levels of nerve injury molecules, nerve injury cytokines, inflammatory cytokines and humoral immune molecules were determined respectively.Results: After 4 weeks and 8 weeks of treatment, serum neuron-specific enolase (NSE), S100β protein (S100β), ubiquitin carboxy-terminal hydrolase L1 (UCH L1), glial fibrillary acid protein (GFAP), hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor α(TNF-α), and interleukin-6 (IL-6) content of both groups were significantly lower than those before treatment (P<0.05) while brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), IgG, IgM and IgA content were significantly higher than those before treatment (P<0.05), and serum NSE, S100β, UCH-L1, GFAP, hs-CRP, TNF-α and IL-6 content of GM1 group were significantly lower than those of control group (P<0.05) while BDNF, NGF, IgG, IgM and IgA content were significantly higher than those of control group (P<0.05).Conclusions: Adjuvant ganglioside sodium therapy can relieve the nerve injury, inhibit the inflammatory reaction and improve the humoral immune response in patients with acute severe craniocerebral injury.

    Prediction of rectal cancer response to preoperative, neo-adjuvant chemo-radiation therapy (CRT) provides the opportunity to identify patients in whom a major response is expected and who may therefore benefit from alternative surgical approaches. Traditional morphological imaging techniques are effective in defining tumour extension in the initial diagnostic and staging work-up, but perform poorly in distinguishing residual neoplastic tissue from scarring post CRT, when restaging the patient before surgery. Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is a promising tool for monitoring the effect of anti-tumour therapy. The aim of this study was to prospectively assess the value of sequential FDG-PET scans in predicting the response of locally advanced rectal cancer to neo-adjuvant CRT. Forty-four consecutive patients with locally advanced (cT3-4) primary rectal cancer and four patients with pelvic recurrence of rectal cancer were enrolled in this prospective study. Treatment consisted of external beam intensified radiotherapy, chemotherapy and, 8-10 weeks later, surgery with curative intent. All patients underwent FDG-PET/CT both before CRT and 5-6 weeks after completing CRT. One patient died before surgery because of acute myocardial infarction, and was therefore excluded from further analysis. Semi-quantitative measurements of FDG uptake (SUV{sub max}), absolute difference ({delta}SUV{sub max}) and percent SUV{sub max} difference (Response Index, RI) between pre- and post-CRT PET scans were considered. Results were correlated with pathological response, assessed both by histopathological staging of the surgical specimens (pTNM) and by the tumour regression grade (TRG) according to Mandard's criteria (patients with TRG1-2 being defined as responders and patients with TRG3-5 as non-responders). Following neo-adjuvant CRT, of the 45 patients submitted to surgery, 23 (51.1%) were classified as responders according to Mandard

    Background: Tumor bed stereotactic radiosurgery (SRS) after resection of brain metastases is a new strategy to delay or avoid whole-brain irradiation (WBRT) and its associated toxicities. This retrospective study analyzes results of frameless image-guided linear accelerator (LINAC)-based SRS and stereotactic hypofractionated radiotherapy (SHRT) as adjuvant treatment without WBRT. Materials and methods: Between March 2009 and February 2012, 44 resection cavities in 42 patients were treated with SRS (23 cavities) or SHRT (21 cavities). All treatments were delivered using a stereotactic LINAC. All cavities were expanded by {>=} 2 mm in all directions to create the clinical target volume (CTV). Results: The median planning target volume (PTV) for SRS was 11.1 cm{sup 3}. The median dose prescribed to the PTV margin for SRS was 17 Gy. Median PTV for SHRT was 22.3 cm{sup 3}. The fractionation schemes applied were: 4 fractions of 6 Gy (5 patients), 6 fractions of 4 Gy (6 patients) and 10 fractions of 4 Gy (10 patients). Median follow-up was 9.6 months. Local control (LC) rates after 6 and 12 months were 91 and 77 %, respectively. No statistically significant differences in LC rates between SRS and SHRT treatments were observed. Distant brain control (DBC) rates at 6 and 12 months were 61 and 33 %, respectively. Overall survival (OS) at 6 and 12 months was 87 and 63.5 %, respectively, with a median OS of 15.9 months. One patient treated by SRS showed symptoms of radionecrosis, which was confirmed histologically. Conclusion: Frameless image-guided LINAC-based adjuvant SRS and SHRT are effective and well tolerated local treatment strategies after resection of brain metastases in patients with oligometastatic disease.

    Purpose/Objectives: To assess the effect and toxicity of hypofractionated high-dose intensity modulated radiation therapy (IMRT) with concurrent and adjuvant temozolomide (TMZ) in 46 patients with newly diagnosed glioblastoma multiforme (GBM). Methods and Materials: All patients underwent postsurgical hypofractionated high-dose IMRT. Three layered planning target volumes (PTVs) were contoured. PTV1 was the surgical cavity and residual tumor on T1-weighted magnetic resonance images with 5-mm margins, PTV2 was the area with 15-mm margins surrounding the PTV1, and PTV3 was the high-intensity area on fluid-attenuated inversion recovery images. Irradiation was performed in 8 fractions at total doses of 68, 40, and 32 Gy for PTV1, PTV2, and PTV3, respectively. Concurrent TMZ was given at 75 mg/m{sup 2}/day for 42 consecutive days. Adjuvant TMZ was given at 150 to 200 mg/m{sup 2}/day for 5 days every 28 days. Overall and progression-free survivals were evaluated. Results: No acute IMRT-related toxicity was observed. The dominant posttreatment failure pattern was dissemination. During a median follow-up time of 16.3 months (range, 4.3-80.8 months) for all patients and 23.7 months (range, 12.4-80.8 months) for living patients, the median overall survival was 20.0 months after treatment. Radiation necrosis was diagnosed in 20 patients and was observed not only in the high-dose field but also in the subventricular zone (SVZ). Necrosis in the SVZ was significantly correlated with prolonged survival (hazard ratio, 4.08; P=.007) but caused deterioration in the performance status of long-term survivors. Conclusions: Hypofractionated high-dose IMRT with concurrent and adjuvant TMZ altered the dominant failure pattern from localized to disseminated and prolonged the survival of patients with GBM. Necrosis in the SVZ was associated with better patient survival, but the benefit of radiation to this area remains controversial.

Grade III toxicity was similar between groups; however, neurotoxicity was significantly greater with 5FU+LEV (p=0.02 and gastrointestinal toxicity with 5FU+LV (p=0.03. Female patients treated with 5FU+LEV had improved overall survival.Conclusions: Adjuvant treatment of CRC is still based on leucovorin modulated fluorouracil. The long-term follow-up results of this trial indicate that the adjuvant treatment of Stage II-III CRC with 5FU+LV or 5FU+LEV is equally effective. The finding of improved survival in female subjects treated with 5FU+LEV warrants further study to determine if Levamisole is a better modulator of 5-FU than Leucovorin in this patient subset.

    The predictive value of thymidylate synthase (TS) expression alone for 5FU-based treatment of colorectal cancer (CRC) has not been clinically confirmed. Little is known on the association of expression of E2F1, which controls the transcription of genes encoding proteins engaged in DNA synthesis including TS, and survival of patients with CRC. The purpose of this study is to assess the correlation between expression of both E2F1 and TS in CRCs and survival of patients administered adjuvant 5FU-based chemotherapy, in order to find a better predictor of treatment outcome than expression of TS or E2F1 alone. Nuclear TS and E2F1 were detected by immunohistochemistry in tissue microarrays from 190 CRCs (Astler-Coller stage B2 or C). Multivariate analysis identified significant association of the combined E2F1+TS+ immunophenotype with worse OS (HR = 3,78, P = 0,009) and DFS (HR = 2,30, P = 0,03) of patients with colon cancer. There were significant differences between E2F1+TS+ and E2F1-TS- Kaplan-Meier survival curves in relation to DFS (P = 0.008) and OS (P = 0.01). About 37 and 31 % difference in 3-year DFS and OS respectively were seen between patients with E2F1+TS+ vs. E2F1-TS- colon cancer immunophenotype. The E2F1+TS+ immunophenotype may be a marker of poor prognosis (the worst DFS and OS) of patients with colon cancer treated with 5FU-based adjuvant therapy. A subgroup of patients with this immunophenotype may require different and perhaps more aggressive treatment than 5FU-based chemotherapy. Thus, the combined E2F1/TS immunophenotype could be a potential indicator of colon cancer sensitivity to 5FU.

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

    After a total mastectomy in cases of a high risk of loco-regional recurrence the postoperative irradiation of the chest wall is indicated in the following situations: Inflammatory type of carcinoma, tumor stage T3-T4, extended multifocal and multicentric primary tumor. After radical axillary surgery even in patients with positive nodes irradiation is not necessary except in cases where all axillary nodes are involved or with invasion of the axillary tissue. The supra- and infraclavicular lymph drainage regions cautially to the operated area (clip) should be irradiated with 50 Gy provided both an enlarged or subtotal involvement can be diagnosed. The irradiation of the retrosternal lymph-drainage system with 45-50 Gy is indicated as follows: Medial or central tumor site, extensive involvement of the axillary nodes and advanced stages of the primary tumor (T2-T4). Axillary irradiation alone cannot serve as a substitute for surgery. After segmental mastectomy without postoperative radiotherapy a local failure rate of 30% is to be expected during a 5 year period. After surgery with adjuvant postoperative irradiation the local failure rate can be reduced to about 5%: 50-60 Gy should be applicated. In case of an unfavourable histology an additional boost dose is recommended. The objective of breast cancer irradiation is to achieve freedom of loco-regional recurrence. The survival can be improved occasionally after local irradiation, theoretically improvement of survival can be achieved in 7-10% at the most.

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

    Full Text Available Background. Three nomogram models for early stage uterine cervical cancer have been developed (KROG 13-03 for overall survival [OS], SNUH/AMC for disease-free survival [DFS], and KROG 12-08 for distant metastases-free survival [DMFS] after radical hysterectomy (RH and pelvic lymph node dissection (PLND. This study aimed to validate these models using our cohort with adjuvant radiotherapy. Methods. According to the eligibility criteria of nomogram studies, patients were enrolled in Group A (N=109 for the two KROG models (RH with PLND and whole pelvic irradiation and Group B (N=101 for the SNUH/AMC model (RH with PLND and squamous histology. Using Cox-regression hazard models, the prognostic factors of our cohorts were evaluated. The risk probabilities induced from published nomogram scores were calculated and the concordance indices were evaluated. Results. Group A had 88.1% 5-year OS and 86.0% 5-year DMFS. Group B had 83.0% 5-year DFS. In multivariate analyses, large tumor size for OS (HR 8.62, P<0.001 and DMFS (HR 5.13, P=0.003, young age (≤40 versus 41–64 years for OS (HR 4.63, P=0.097 and DFS (HR 3.44, P=0.051, and multiple lymph node metastases (0 versus ≥3 for DMFS (HR 4.03, P=0.031 and DFS (HR 3.90, P=0.038 were significantly correlated. The concordance indices for OS, DMFS, and DFS were 0.612 (P=0.002, 0.597 (P=0.014, and 0.587 (P=0.020, respectively. Conclusion. The developed nomogram models after RH and PLND are clinically useful in predicting various types of survival with significance.

  7. Regulation of the CCN genes by vitamin D: A possible adjuvant therapy in the treatment of cancer and fibrosis.

    The CCN family is composed of six cysteine-rich, modular, and conserved proteins whose functions span a variety of tissues and include cell proliferation, adhesion, angiogenesis, and wound healing. Roles for the CCN proteins throughout the entire body including the skin, kidney, brain, blood vessels, hematopoietic compartment and others, are continuously being elucidated. Likewise, an understanding of the regulation of this important gene family is constantly becoming clearer, through identification of transcription factors that directly activate, repress, or respond to upstream cell signaling pathways, as well as other forms of gene expression control. Vitamin D (1,25-dihydroxyvitamin D3 or calcitriol), a vitamin essential for numerous biological processes, acts as a potent gene expression modulator. The regulation of the CCN gene family members by calcitriol has been described in many contexts. Here, we provide a concise and thorough overview of what is known about calcitriol and its regulation of the CCN genes, and argue that its regulation is of physiological importance in a wide breadth of tissues in which CCN genes function. In addition, we highlight the effects of vitamin D on CCN gene expression in the setting of two common pathologic conditions, fibrosis and cancer, and propose that the therapeutic effects of vitamin D3 described in these disease states may in part be attributable to CCN gene modulation. As vitamin D is perfectly safe in a wide range of doses and already showing promise as an adjuvant therapeutic agent, a deeper understanding of its control of CCN gene expression may have profound implications in clinical management of disease.

    Purpose To describe benefits and toxicities of adjuvant endocrine therapies in women younger than 35 years with breast cancer (n = 582) enrolled in the Suppression of Ovarian Function Trial (SOFT) and Tamoxifen and Exemestane Trial (TEXT). Methods In SOFT, women still premenopausal after surgery with or without chemotherapy were randomly assigned to tamoxifen alone, tamoxifen plus ovarian function suppression (OFS), or exemestane plus OFS. In TEXT, all received OFS with or without concomitant chemotherapy and were randomly assigned to exemestane plus OFS or tamoxifen plus OFS. We summarize treatment efficacy, quality of life, and adherence of the cohort of women younger than 35 years in SOFT and TEXT, alongside data from the cohort of older premenopausal women. Results For 240 human epidermal growth factor receptor 2-negative patients younger than 35 years enrolled in SOFT after receiving chemotherapy, the 5-year breast cancer-free interval (BCFI) was 67.1% (95% CI, 54.6% to 76.9%) with tamoxifen alone, 75.9% with tamoxifen plus OFS (95% CI, 64.0% to 84.4%), and 83.2% with exemestane plus OFS (95% CI, 72.7% to 90.0%). For 145 human epidermal growth factor receptor 2-negative patients younger than 35 years in TEXT, 5-year BCFI was 79.2% (95% CI, 66.2% to 87.7%) with tamoxifen plus OFS and 81.6% (95% CI, 69.8% to 89.2%) with exemestane plus OFS. The most prominent quality of life symptom for patients younger than 35 years receiving OFS was vasomotor symptoms, with the greatest worsening from baseline at 6 months (on the order of 30 to 40 points), but loss of sexual interest and difficulties in becoming aroused were also clinically meaningful (≥ 8-point change). The level of symptom burden was similar in older premenopausal women. A total of 19.8% of women younger than 35 years stopped all protocol-assigned endocrine therapy early. Conclusion In women younger than 35 years with hormone receptor-positive breast cancer, adjuvant OFS combined with tamoxifen or

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

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

    We report a case of refractory heparin-induced thrombocytopenia with thrombosis (HITT) with prolonged thrombocytopenia and multiple thrombotic complications that failed to improve despite aggressive treatment. A 60 year old female with a prior history of venous thromboembolism was admitted with an acute pulmonary embolism, and developed HITT after several days on heparin therapy. She suffered multiple complications including bilateral venous limb gangrene, acute renal failure, and refractory thrombocytopenia, leading us to use multimodality therapy including therapeutic plasma exchange (TPE) and rituximab immunosuppression. The patient had transient improvements in her thrombocytopenia with TPE, and rituximab was added in an attempt to reduce antibody production. She eventually required bilateral limb amputation, and only after removal of the gangrenous limbs did her platelet count show sustained improvement. We discuss the possible contribution of infection to her prolonged course.

    Full Text Available According to WHO reports Hepatocellular carcinoma remains an Asian health problem. Its prevalence disproportionately shares large of the world's nearly 78%. Treatment options of HCC are limited and the effectiveness of treatment varies due to development of therapy-related adverse effects in Allopathic medicine. We report herein a case of HCC admitted to Sir Sundarlal Hospital, Banaras Hindu University, Varanasi was treated with integrated Ayurvedic herbo – mineral medicine, with desirable results of improvement in QoL. The patient was treated with a holistic inter disciplinary approach i.e., Modern medicine treatment followed by Ayurveda, health education for cancer care and psychotherapeutic measures such as Yoga, psychological counseling etc. The symptoms were managed according to its clinical presentation and daily clinical evaluation. This paper demonstrates the findings of our experience in treating a case of HCC with Ayurvedic herbo mineral medicine as an adjuvant treatment for improvement of QoL. Moreover, it emphasized the needs to be explored Ayurvedic cancer management with more advance methodology.

    The purpose of this meta-analysis was to analyze the available evidence concerning the effects of depression on non-adherence to adjuvant endocrine therapy (AET) in women with breast cancer. MEDLINE and PsycInfo databases from inception through May 1, 2015 were searched using terms related to AET adherence. Articles were reviewed and selected based on predetermined selection criteria, and effect sizes from included studies were extracted. Pooled effect estimates were obtained using random-effects meta-analyses. Of the 312 articles identified, 9 met the inclusion criteria. Overall, depression was significantly associated with non-adherence to AET (Cohen's d = 0.35, 95% CI 0.19-0.52). This effect was not significantly moderated by patient age (adherence (objective vs self-report). However, within these subgroups, significant effects of depression were found only for younger patients (d = 0.46; 95% CI 0.19-0.72) and in studies of shorter duration (adherence may be lower among women with greater depressive symptoms, and this effect may be exacerbated in younger women during the early phases (breast cancer may help in enhancing adherence to AET and improve cancer treatment outcomes.

    2016-10-01

    Cognitive behavioral therapy (CBT) is recognized as an effective treatment for obsessive-compulsive disorder (OCD). To maximize its effectiveness, we designed an "experimental" CBT defined by the addition of a computerized psychoeducative tool. In a participative process involving patients through meetings of the French OCD association (AFTOC) and therapists through methodological workshops, we built a therapeutic tool from an experimental checking task. This task, which had been published in an earlier work, was adapted for its psychoeducative dimension. We here report on a randomized double-blind trial which included 35 patients with a moderate to severe OCD (Yale-Brown obsessive-compulsive scale, YBOCS between 16 and 25) predominant checking symptoms, no comorbidities, and 2-month stabilized or no treatment. Patients were randomly assigned to either "standard" versus "experimental" CBT. Both therapies were conducted by four CBT-experienced therapists specialized in OCD through weekly individualized sessions over 3 months. Therapy sessions of the experimental CBT were conducted as the standard CBT except for a short exercise with the computerized psychoeducative tool performed by the patient and debriefed with the therapist at the end of the sessions. Patients were assessed before, during, after therapy and again 6 months later using standard clinical tools and a neurobehavioral assessment based on an original symptom-provocation task with anxiety ratings including three types of photographs: neutral, generic inducing obsessions (e.g., doorknobs, electric wires…) and personalized (taken by the patients in their own environment). Clinically, "standard" and "experimental" CBT resulted in a significant but equivalent improvement (48% vs 45% reduction of the Y-BOCS score; P=0.36; d=0.12). Therapists were satisfied with the psychoeducative dimension of the computerized psychoeducative tool but reported variable acceptance across patients. Patients appreciated its

Median follow-up for patients without recurrence was 12 months. Patients were randomized to BCG or mononuclear cells collected by apheresis after ex vivo cell processing and activation (BEXIDEM. Either arm treatment consisted of 6 weekly instillations and 2 cycles of 3 weekly instillations at months 3 and 6. Toxicity profile (primary endpoint and prophylactic effects (secondary endpoint were assessed. Results Patient characteristics were evenly distributed. Of 73 treated with BCG and 64 with BEXIDEM, 85% vs. 45% experienced AEs and 26% vs. 14% serious AEs (SAE, respectively (p Discussion This initial report of autologous intravesical macrophage cell therapy in BC demonstrates BEXIDEM treatment to be safe. Recurrence rates were significantly lower with BCG however. As the efficacy of BEXIDEM remains uncertain, further data, e.g. marker lesions studies, are warranted.

    Full Text Available This study aimed to evaluate the survival rate of women with breast cancer (BC comparing persistence versus interruption and adherence versus non-adherence to adjuvant hormonal therapy (HT in Asian population. Newly-diagnosed BC women from 2003 to 2010 were retrospectively identified from the Taiwan National Health Insurance Research Database. HT prescriptions were extracted to define treatment interruption and medication possession ratio. Their impacts on mortality were estimated by Cox regression with time dependent covariates. Interruption (HR: 1.32; 95% CI: 1.20, 1.46; P<0.0001 and non-adherence (HR: 1.45; 95% CI: 1.32, 1.59; P<0.0001 to adjuvant HT were significantly associated with increased mortality. Interruption to tamoxifen in younger patients and in patients receiving surgery (OP with adjuvant chemotherapy (CT was associated with increasing mortality rate when compared with their counterparts. Non-adherence to AIs in both younger and senior age groups and in OP with CT group also resulted in increasing risk. Treatment interruption and non-adherence to adjuvant HT were found to be associated with the increasing all-cause mortality of the Asian BC women; a greater impact of interruption and non-adherence on mortality was especially found in the younger BC population.

    Vaccines are essential tools for the prevention and control of infectious diseases in animals. One of the most important steps in vaccine development is the selection of a suitable adjuvant. The focus of this review is the adjuvants used in vaccines for animals. We will discuss current commercial adjuvants and experimental formulations with attention to mineral salts, emulsions, bacterial-derived components, saponins, and several other immunoactive compounds. In addition, we will also examine the mechanisms of action for different adjuvants, examples of adjuvant combinations in one vaccine formulation, and challenges in the research and development of veterinary vaccine adjuvants.

    2016-04-01

    The aim of this review is to address the current status of adjuvant chemotherapy alone in early-stage cervical cancer treatments in the literature. At present, the therapeutic effect of adjuvant chemotherapy alone after radical surgery (RS) has not yet been established, and radiation therapy (RT) or concurrent chemoradiotherapy (CCRT) is recommended as the standard adjuvant therapy after RS for early-stage cervical cancer in various guidelines. The main purpose of adjuvant therapy after RS, however, should be to reduce extrapelvic recurrence rather than local recurrence, although adjuvant RT or CCRT has survival benefits for patients with intermediate- or high-risk factors for recurrence. Moreover, several studies reported that adjuvant therapies including RT were associated with a higher incidence of complications, such as lymphedema, bowel obstruction and urinary disturbance, and a lower grade of long-term quality of life (QOL) or sexual functioning than adjuvant chemotherapy alone. The effect of adjuvant chemotherapy alone for early-stage cervical cancer with intermediate- or high-risk factors for recurrence were not fully investigated in prospective studies, but several retrospective studies suggest that the adjuvant effects of chemotherapy alone are at least similar to that of RT or CCRT in terms of recurrence rate, disease-free survival, or overall survival (OS) with lower incidence of complications. Whereas cisplatin based combination regimens were used in these studies, paclitaxel/cisplatin (TP) regimen, which is currently recognized as a standard chemotherapy regimen for patients with metastatic, recurrent or persistent cervical cancer by Gynecologic Oncology Group (GOG), had also survival benefit as an adjuvant therapy. Therefore, it may be worth considering a prospective randomized controlled trial (RCT) of adjuvant chemotherapy alone using TP regimen versus adjuvant RT as an alternative adjuvant therapy. Because early-stage cervical cancer is a curable

    2010-06-01

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

    2012-06-01

    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.

    The AZURE trial is an ongoing phase III, academic, multi-centre, randomised trial designed to evaluate the role of zoledronic acid (ZOL) in the adjuvant therapy of women with stage II/III breast cancer. Here, we report the safety and tolerability profile of ZOL in this setting. Eligible patients received (neo)adjuvant chemotherapy and/or endocrine therapy and were randomised to receive neither additional treatment nor intravenous ZOL 4 mg. ZOL was administered after each chemotherapy cycle to exploit potential sequence-dependent synergy. ZOL was continued for 60 months post-randomisation (six doses in the first 6 months, eight doses in the following 24 months and five doses in the final 30 months). Serious (SAE) and non-serious adverse event (AE) data generated during the first 36 months on study were analysed for the safety population. 3,360 patients were recruited to the AZURE trial. The safety population comprised 3,340 patients (ZOL 1,665; control 1,675). The addition of ZOL to standard treatment did not significantly impact on chemotherapy delivery. SAE were similar in both treatment arms. No significant safety differences were seen apart from the occurrence of osteonecrosis of the jaw (ONJ) in the ZOL group (11 confirmed cases; 0.7%; 95% confidence interval 0.3-1.1%). ZOL in the adjuvant setting is well tolerated, and can be safely administered in addition to adjuvant therapy including chemotherapy. The adverse events were consistent with the known safety profile of ZOL, with a low incidence of ONJ.

    Full Text Available Carol M Ulloa, Allen Towfigh, Joseph SafdiehDepartment of Neurology and Neuroscience, Weill Medical College of Cornell University, New York, NY, USAAbstract: Levetiracetam is a second-generation antiepileptic drug (AED with a unique chemical structure and mechanism of action. The extended release formulation of levetiracetam (Keppra XR™; UCB Pharma was recently approved by the Food and Drug Administration for adjunctive therapy in the treatment of partial-onset seizures in patients 16 years of age and older with epilepsy. This approval is based on a double-blind, randomized, placebo-controlled, multicenter, multinational trial. Levetiracetam XR allows for once-daily dosing, which may increase compliance and, given the relatively constant plasma concentrations, may minimize concentration-related adverse effects. Levetiracetam’s mode of action is not fully elucidated, but it has been found to target high-voltage, N-type calcium channels as well as the synaptic vesicle protein 2A (SV2A. Levetiracetam has nearly ideal pharmacokinetics. It is rapidly and almost completely absorbed after oral ingestion, is ‹10% protein-bound, demonstrates linear kinetics, is minimally metabolized through a pathway independent of the cytochrome P450 system, has no significant drug–drug interactions, and has a wide therapeutic index. The most common reported adverse events with levetiracetam XR were somnolence, irritability, dizziness, nausea, influenza, and nasopharyngitis. Levetiracetam XR provides an efficacious and well-tolerated treatment option for adjunctive therapy in the treatment of partial-onset seizures.Keywords: levetiracetam, partial-onset seizures, antiepileptic drugs

    AIM: To investigate the time course of testosterone(T) recovery after cessation of androgen deprivation therapy(ADT) in patients treated with brachytherapy. METHODS: One-hundred and seventy-four patients treated between June 1999 and February 2009 were studied. Patients were divided into a short-term usage group(≤ 12 mo, n = 91) and a long-term usage group(≥ 36 mo, n = 83) according to the duration of gonadotropin-releasing hormone agonist therapy. Median follow-up was 29 mo in the short-term group and was 60 mo in the long-term group.RESULTS: Cumulative incidence rates of T recovery to normal and supracastrate levels at 24 mo after cessationwere 28.8% and 74.6%, respectively, in the long-term usage group, whereas these values were 96.4% and 98.8% in the short-term usage group. T recovery to normal and supracastrate levels occurred significantly more rapidly in the short-term than in the long-term usage group(P < 0.001 and P < 0.001, respectively). Five years after cessation, 22.6% of patients maintained a castrate T level in the long-term usage group. On multivariate analysis, lower T levels(< 10 ng/d L) at cessation of ADT was significantly associated with prolonged T recovery to supracastrate levels in the longterm usage group(P = 0.002). CONCLUSION: Lower T levels at cessation of ADT were associated with prolonged T recovery in the longterm usage group. Five years after cessation of longterm ADT, approximately one-fifth of patients still had castrate T levels. When determining the therapeutic effect, especially biochemical control, we should consider this delay in T recovery.

    2009-09-01

    There is a renewed enthusiasm about subunit vaccines for malaria coincident with the formation of new alliances and partnerships raising international public awareness, attracting increased resources and the re-focusing of research programs on adjuvant development for infectious disease vaccines. It is generally accepted that subunit vaccines for malaria will require adjuvants to induce protective immune responses, and availability of suitable adjuvants has in the past been a barrier to the development of malaria vaccines. Several novel adjuvants are now in licensed products or in late stage clinical development, while several others are in the earlier development pipeline. Successful vaccine development requires knowing which adjuvants to use and knowing how to formulate adjuvants and antigens to achieve stable, safe, and immunogenic vaccines. For the majority of vaccine researchers this information is not readily available, nor is access to well-characterized adjuvants. In this minireview, we outline the current state of adjuvant research and development as it pertains to effective malaria vaccines.

    Breast cancer is the most frequent malignant neoplasm in women. The evaluation of the quality of life has become a treatment parameter as important as survival. The aim of the study was evaluation of the quality of life among women treated for breast cancer who underwent surgical procedures using two alternative methods: mastectomy or breast conserving therapy (BCT). 85 patients treated with BCT and 94 patients who underwent mastectomy were evaluated. Standard questionnaires for the evaluation of the quality of life of cancer patients were used - QLQ-C30 (Quality of life questionnaire - core 30) with QLQ-BR23 (Breast Cancer Module). The Hospital Anxiety and Depression Scale was also applied. Social and demographic factors (age, education, marital status) influenced the evaluation of the life quality among both groups. Obtained data was also dependent on the type of surgical procedure and chemical treatment. The level of anxiety and depression also influenced the general quality of life and was higher in women who underwent mastectomy. Quality of life plays an important role in the treatment process. Women after BCT declared a higher quality of life compared to patients after mastectomy. The process of making the decision concerning the planned surgical procedure should take into consideration the influence of the intervention on the quality of patients' future life.

    Purpose: To describe the quality of life (QOL) in elderly patients with glioblastoma (GBM) treated with an abbreviated course of radiation therapy (RT; 40 Gy in 15 fractions) plus concomitant and adjuvant temozolomide (TMZ). Methods and Materials: Health-related QOL (HRQOL) was assessed by European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (QLQ-C30, version 3) and EORTC Quality of Life Questionnaire Brain Cancer Module (QLQ-BN20). Changes from baseline in the score of 9 preselected domains (global QLQ, social functioning, cognitive functioning, emotional functioning, physical functioning, motor dysfunction, communication deficit, fatigue, insomnia) were determined 4 weeks after RT and thereafter every 8 weeks during the treatment until disease progression. The proportion of patients with improved HRQOL scores, defined as a change of 10 points or more, and duration of changes were recorded. Results: Sixty-five patients completed the questionnaires at baseline. The treatment was consistently associated with improvement or stability in most of the preselected HRQOL domains. Global health improved over time; mean score differed by 9.6 points between baseline and 6-month follow-up (P=.03). For social functioning and cognitive functioning, mean scores improved over time, with a maximum difference of 10.4 points and 9.5 points between baseline and 6-month follow-up (P=.01 and P=.02), respectively. By contrast, fatigue worsened over time, with a difference in mean score of 5.6 points between baseline and 4-month follow-up (P=.02). Conclusions: A short course of RT in combination with TMZ in elderly patients with GBM was associated with survival benefit without a negative effect on HRQOL until the time of disease progression.

    The aims of this study were to comprehensively describe the psychosocial and medical characteristics of women who initiated tamoxifen or aromatase inhibitors for breast cancer and to compare levels of emotional distress according to their medical (tumor demographics, treatment type, treatment duration) and psychosocial (self-esteem, perceived social support, sociodemographic) characteristics. A total of 104 women currently receiving tamoxifen or aromatase inhibitors was recruited from outpatient clinics and they were asked to complete self-report questionnaires including the Rosenberg Self-Esteem Scale, the Multidimensional Scale of Perceived Social Support and the Hospital Anxiety and Depression Scale during their routine follow-up. Psychosocial and medical characteristics of the patients were first described and subsequently the score of emotional distress was compared with these. The patients' mean age was 52.49 ± 10.30 and they were being treated for an average of 24.3 months. Out of the patients' characteristics, educational and marital status, level of perceived social support and self-esteem were all significantly related with emotional distress. As for medical variables, the score of distress was relatively higher among patients in the first 2 years of their treatment than the patients who were in the second to fifth years of treatment, but this was not statistically significant. Given the results of this study, it appeared that patient variables, rather than the medical or treatment characteristics, were related with emotional distress in women undergoing endocrine treatment. For that reason it is critical that medical staff are aware of patient factors that relate to distress during a long period of adjuvant endocrine therapy.

    The purpose of this analysis was to assess the long-term impact of adding bevacizumab to adjuvant chemotherapy for early triple-negative breast cancer (TNBC). Patients eligible for the open-label randomized phase III BEATRICE trial had centrally confirmed triple-negative operable primary invasive breast cancer (pT1a-pT3). Investigators selected anthracycline- and/or taxane-based chemotherapy for each patient. After definitive surgery, patients were randomized 1:1 to receive ≥4 cycles of chemotherapy alone or with 1 year of bevacizumab (5 mg/kg/week equivalent). Stratification factors were nodal status, selected chemotherapy, hormone receptor status, and type of surgery. The primary end point was invasive disease-free survival (IDFS; previously reported). Secondary outcome measures included overall survival (OS) and safety. After 56 months' median follow-up, 293 of 2591 randomized patients had died. There was no statistically significant difference in OS between treatment arms in either the total population (hazard ratio 0.93, 95% confidence interval [CI] 0.74-1.17; P = 0.52) or pre-specified subgroups. The 5-year OS rate was 88% (95% CI 86-90%) in both treatment arms. Updated IDFS results were consistent with the primary IDFS analysis. Five-year IDFS rates were 77% (95% CI 75-79%) with chemotherapy alone versus 80% (95% CI 77-82%) with bevacizumab. From 18 months after first study dose to study end, new grade ≥3 adverse events occurred in 4.6% and 4.5% of patients in the two arms, respectively. Final OS results showed no significant benefit from bevacizumab therapy for early TNBC. Late-onset toxicities were rare in both groups. Five-year OS and IDFS rates suggest that the prognosis for patients with TNBC is better than previously thought. NCT00528567.

    Full Text Available Abstract Introduction Black women appear to have worse outcome after diagnosis and treatment of breast cancer. It is still unclear if this is because Black race is more often associated with known negative prognostic indicators or if it is an independent prognostic factor. To study this, we analyzed a patient cohort from an urban university medical center where these women made up the majority of the patient population. Methods We used retrospective analysis of a prospectively collected database of breast cancer patients seen from May 1999 to June 2006. Time to recurrence and survival were analyzed using the Kaplan-Meier method, with statistical analysis by chi-square, log rank testing, and the Cox regression model. Results 265 female patients were diagnosed with breast cancer during the time period. Fifty patients (19% had pure DCIS and 215 patients (81% had invasive disease. Racial and ethnic composition of the entire cohort was as follows: Black (N = 150, 56.6%, Hispanic (N = 83, 31.3%, Caucasian (N = 26, 9.8%, Asian (N = 4, 1.5%, and Arabic (N = 2, 0.8%. For patients with invasive disease, independent predictors of poor disease-free survival included tumor size, node-positivity, incompletion of adjuvant therapy, and Black race. Tumor size, node-positivity, and Black race were independently associated with disease-specific overall survival. Conclusion Worse outcome among Black women appears to be independent of the usual predictors of survival. Further investigation is necessary to identify the cause of this survival disparity. Barriers to completion of standard post-operative treatment regimens may be especially important in this regard.

    Purpose: The aim of our study was to evaluate patterns and predictors of early biochemical recurrence (eBCR) after radical prostatectomy (RP) and adjuvant radiation therapy (aRT) in order to identify which individuals might benefit from additional treatments. Methods and Materials: We evaluated 390 patients with pT{sub 3}N{sub 0} prostate cancer (PCa) receiving RP and aRT at 6 European centers between 1993 and 2006. Patients who were free from BCR at <2 years' follow-up were excluded. This resulted in 374 assessable patients. Early BCR was defined as 2 consecutive prostate-specific antigen (PSA) test values >0.2 ng/mL within 2 or 3 years after aRT. Uni- and multivariable Cox regression analyses predicting overall and eBCR after aRT were fitted. Covariates consisted of preoperative PSA results, surgical margins, pathological stage, Gleason score, and aRT dose. Results: Overall, 5- and 8-year BCR-free survival rates were 77.1% and 70.8%, respectively. At a median follow-up of 86 months after aRT, 33 (8.8%) and 55 (14.6%) men experienced BCR within 2 or 3 years after aRT, respectively. In multivariable analyses, Gleason scores of 8 to 10 represented the only independent predictor of eBCR after aRT (all, P≤.01). The risk of BCR was significantly higher in patients with a Gleason score of 8 to 10 disease than in those with Gleason 2 to 6 within 24 months after treatment, after adjusting for all covariates (all, P≤.04). However, given a 24-month BCR free period, the risk of subsequent BCR for men with poorly differentiated disease was equal to that of men with less aggressive disease (all, P≥.3). Conclusions: High Gleason score represents the only predictor of eBCR after RP and aRT in patients affected by pT{sub 3}N{sub 0} PCa. Given the association between early PSA recurrence, clinical progression, and mortality, these patients might be considered candidates for adjuvant medical therapy and/or prophylactic whole-pelvis radiation therapy in addition to a

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

    Purpose Previous studies suggest that adherence to adjuvant endocrine therapy (AET) for patients with breast cancer is suboptimal, especially among minorities, and is associated with out-of-pocket medication costs. This study aimed to determine whether there are racial/ethnic differences in 1-year adherence to AET and whether out-of-pocket costs explain the racial/ethnic disparities in adherence. Methods This retrospective cohort study used the SEER-Medicare linked database to identify patients ≥ 65 years of age with hormone receptor-positive breast cancer who were enrolled in Medicare Part D from 2007 to 2009. The cohort included non-Hispanic whites, blacks, Hispanics, and Asians. Out-of-pocket costs for AET medications were standardized for a 30-day supply. Adherence to tamoxifen, aromatase inhibitors (AIs), and overall AET (tamoxifen or AIs) was assessed using the medication possession ratio (≥ 80%) during the 12-month period. Results Of 8,688 patients, 3,197 (36.8%) were nonadherent to AET. Out-of-pocket costs for AET medication were associated with lower adjusted odds of adherence for all four cost categories compared with the lowest category of ≤ $2.65 ( P adherence to any AET at initiation (OR, 1.30; 95% CI, 1.07 to 1.57), and blacks had higher odds of adherence to AIs at initiation (OR, 1.27; 95% CI, 1.04 to 1.54) compared with non-Hispanic whites. After adjusting for copayments, poverty status, and comorbidities, the association was no longer significant for Hispanics (OR, 0.95; 95% CI, 0.78 to 1.17) or blacks (OR, 0.96; 95% CI, 0.77 to 1.19). Blacks had significantly lower adjusted odds of adherence than non-Hispanic whites when they initiated AET therapy with tamoxifen (OR, 0.54; 95% CI, 0.31 to 0.93) after adjusting for socioeconomic, clinic, and prognostic factors. Conclusion Racial/ethnic disparities in AET adherence were largely explained by women's differences in socioeconomic status and out-of-pocket medication costs.

    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.

    Adjuvant is originated from the Latin word "adjuvare" which means "help" in English to enhance the immunological responses when given together with antigens. The beginning of adjuvant was mineral oil which enhanced the immune response when it was given with inactivated Salmonella typhimurium. Aluminium salt was used to precipitate diphtheria toxoid and increased level of antibody response was demonstrated when administered with alum-precipitated antigens. Since 1930, aluminium salt has been used as DTaP (diphtheria-tetanus-acellular pertussis vaccine) adjuvant. Many candidates were tested for adjuvant activity but only aluminum salt is allowed to use for human vaccines. New adjuvant MF59, oil-in-water emulsion type, was developed for influenza vaccine for elderly (Fluad) and series of AS adjuvant are used for hepatitis B, pandemic flue, and human papiloma virus vaccines. Oil-adjuvanted influenza pandemic vaccines induced higher antibody response than alum-adjuvanted vaccine with higher incidence of adverse events, especially for local reactions. Alum-adjuvanted whole virion inactivated H5N1 vaccine was developed in Japan, and it induced relatively well immune responses in adults. When it applied for children, febrile reaction was noted in approximately 60% of the subjects, with higher antibodies. Recent investigation on innate immunity demonstrates that adjuvant activity is initiated from the stimulation on innate immunity and/or inflammasome, resulting in cytokine induction and antigen uptake by monocytes and macrophages. The probable reason for high incidence of febrile reaction should be investigated to develop a safe and effective influenza vaccine.

    Purpose The aim of the present study was to evaluate the effectiveness of hyaluronic acid (HA) in the prevention of acute and late vaginal toxicities after high-dose-rate (HDR) vaginal brachytherapy (BT). Material and methods Between January 2011 and January 2015, we retrospectively analyzed 126 patients with endometrial cancer who underwent extrafascial hysterectomy with or without lymphadenectomy and adjuvant HDR-vaginal BT +/– adjuvant chemotherapy. The total dose prescription was 21 Gy in 3 fractions (one fraction for week). Vaginal ovules containing 5 mg of HA were given for whole duration of vaginal BT and for the two following weeks. Acute and late toxicities were evaluated according to CTCAE vs 4.02. Results According to the revised FIGO 2009 classification, most tumors were in stage IA (30.9%) and in stage IB (57.9%). Thirty-three patients (26.2%) received adjuvant chemotherapy before vaginal BT. Five-year disease-free survival (DFS) and five-year overall survival (OS) were 88% and 93%, respectively. The most common grade 1-2 acute toxicities were vaginal inflammation (18 patients, 14.3%) and dyspareunia (7 patients, 5.5%). Two patients (1.6%) had more than one toxicity. Late toxicity occurred in 20 patients (15.9%). Grade 1-2 late toxicities were fibrosis (14 patients, 11.1%) and telangiectasias (7 patients, 5.5%). Six patients (4.8%) had more than one late toxicity. No grade 3 or higher acute or late toxicities were observed. Conclusions These results appear to suggest that the local therapy with HA is of clinical benefit for intermediate risk endometrial cancer patients who receive adjuvant HDR-vaginal BT after surgery. A randomized trial comparing HA treatment vs. no local treatment in this clinical setting is warranted to further evaluate the efficacy of HA in preventing vaginal BT-related vaginal toxicity.

    Currently interferon alfa-2b (IFNα-2b) is an approved adjuvant drug for high-risk melanoma patients that leads to an improvement in disease-free survival (DFS). However, it is unclear whether it also impacts overall survival. Widespread use of adjuvant high-dose IFNα has been tempered by its significant toxicity and its limited efficacy. Current therapeutic strategies like immune checkpoint blockade or targeted therapy may also be useful in the adjuvant setting. Therefore, it is important to weigh the trade-offs between possible side effects and therapeutic benefit.We assessed patient utilities for health states associated with IFN therapy. Utilities are measures of preference for a specific health state on a scale of 0 (death) to 1 (perfect health).Utilities were determined for health states associated with adjuvant IFN among 130 German low-risk melanoma patients using the standard gamble technique. Four IFNα-2b toxicity scenarios and the following 3 posttreatment outcomes were assessed: disease-free health and melanoma recurrence (with or without previous use of IFNα-2b) resulting in cancer death. Patients were asked to trade-off the improvement in 5-year DFS and the IFN-related side effects.Utilities for melanoma recurrence (mean 0.60) were significantly lower than for all IFNα-2b toxicity scenarios (mean 0.81-0.90). Patients were willing to tolerate mild-to-moderate and severe toxicity for a 50% and 75% chance of 5-year DFS, respectively. Both utilities and threshold benefits were mostly independent from patient characteristics like gender, income, and social situation. Significant impact was only observed by age and previous personal experience with cancer.On average, German patients were willing to trade even severe IFNα-2b toxicity for reducing the rate of melanoma recurrence. This result points out the importance of a relapse-free survival for melanoma patients. The utilities measured in our study can be applied to decision-making processes in

    Purpose: This study was undertaken to determine whether there was an increased risk of second malignancies (SM), particularly lung cancer, in early stage breast cancer patients treated with the addition of nodal fields to breast and/or chest wall radiation therapy (RT). Materials and Methods: Subjects were stage I/II female breast cancer patients 20 to 79 years of age, diagnosed between 1989 and 2005 and treated with adjuvant RT at our institution. Patients were included if they survived and did not have SM within 3 years of diagnosis. Standardized incidence ratios (SIR) with 95% confidence intervals (CI) were calculated to compare SM incidence to cancer incidence in the general sex- and age-matched populations. Secondary malignancy risks in patients treated with local RT (LRT) to the breast/chest wall were compared to those in patients treated with locoregional RT (LRRT) to the breast/chest wall and regional nodes, using multivariate regression analysis (MVA) to account for covariates. Results: The cohort included 12,836 patients with a median follow-up of 8.4 years. LRRT was used in 18% of patients. The SIR comparing patients treated with LRT to the general population was 1.29 (CI: 1.21-1.38). No statistically significant increased incidence of in-field malignancies (SIR, 1.04; CI: 0.87-1.23) and lung cancers (SIR, 1.06; CI: 0.88-1.26) was detected. The SIR comparing patients treated with LRRT to the general population was 1.39 (CI: 1.17-1.64). No statistically significant increased incidence of in-field malignancies (SIR, 1.26; CI: 0.77-1.94) and lung cancers (SIR, 1.27; CI: 0.76-1.98) was detected. On MVA comparing LRRT to LRT, the adjusted hazard ratio was 1.20 for in-field malignancies (CI: 0.68-2.16) and 1.26 for lung cancer (CI: 0.67-2.36). The excess attributable risk (EAR) to regional RT was 3.1 per 10,000 person years (CI: −8.7 to 9.9). Conclusions: No statistically significant increased risk of second malignancy was detected after LRRT relative to

    Full Text Available Abstract Background To report results in terms of feasibility and early toxicity of hypofractionated simultaneous integrated boost (SIB approach with Volumetric Modulated Arc Therapy (VMAT as adjuvant treatment after breast-conserving surgery. Methods Between September 2010 and May 2011, 50 consecutive patients presenting early-stage breast cancer were submitted to adjuvant radiotherapy with SIB-VMAT approach using RapidArc in our Institution (Istituto Clinico Humanitas ICH. Three out of 50 patients were irradiated bilaterally (53 tumours in 50 patients. All patients were enrolled in a phase I-II trial approved by the ICH ethical committee. All 50 patients enrolled in the study underwent VMAT-SIB technique to irradiate the whole breast with concomitant boost irradiation of the tumor bed. Doses to whole breast and surgical bed were 40.5 Gy and 48 Gy respectively, delivered in 15 fractions over 3 weeks. Skin toxicities were recorded during and after treatment according to RTOG acute radiation morbidity scoring criteria with a median follow-up of 12 months (range 8–16. Cosmetic outcomes were assessed as excellent/good or fair/poor. Results The median age of the population was 68 years (range 36–88. According to AJCC staging system, 38 breast lesions were classified as pT1, and 15 as pT2; 49 cases were assessed as N0 and 4 as N1. The maximum acute skin toxicity by the end of treatment was Grade 0 in 20/50 patients, Grade 1 in 32/50, Grade 2 in 0 and Grade 3 in 1/50 (one of the 3 cases of bilateral breast irradiation. No Grade 4 toxicities were observed. All Grade 1 toxicities had resolved within 3 weeks. No significant differences in cosmetic scores on baseline assessment vs. 3 months and 6 months after the treatment were observed: all patients were scored as excellent/good (50/50 compared with baseline; no fair/poor judgment was recorded. No other toxicities or local failures were recorded during follow-up. Conclusions The 3

    Background: Intensity modulated radiotherapy (IMRT) provides better sparing of normal tissue. We investigated the feasibility of inverse treatment planning for IMRT in adjuvant radiotherapy for breast cancer. Material and Methods: In addition to radiotherapy planning in conventional technique with tangential wedged 6-MV-photon beams we performed inversely planned IMRT (KonRad trademark). In the CT scans for treatment planning we defined a 10-mm bolus of -60 HE density. The influence of this bolus on planning optimization was determined by optimization without and dose calculation with and without bolus. Dose calculation after dose optimization with bolus was performed using different bolus thickness to determine the influence of the bolus on dose calculation. The results were compared with dose distribution in conventional technique. Results: Inverse optimization with a dose algorithm which considers tissue inhomogeneity results in unintended dose increase at the patient surface. With a virtual 10-mm bolus used for inverse optimization the dose increase was reduced. Thus, skin sparing was identical to conventional planning. The relative dose distribution was negligibly affected by the use of a 10-mm bolus. Difference in absolute dose was 3.4% compared to calculation without bolus. Therefore, the bolus must be removed before final dose calculation. (orig.)

    Curcuminoids are bioactive polyphenolics with potent antiinflammatory properties. Although several lines of in vitro and preclinical evidence suggest potent anticancer effects of curcuminoids, clinical findings have not been conclusive. The present randomized double-blind placebo-controlled trial aimed to evaluate the efficacy of curcuminoids as adjuvant therapy in cancer patients. Eighty subjects with solid tumors who were under standard chemotherapy regimens were randomly assigned to a bioavailability-boosted curcuminoids preparation (180 mg/day; n = 40) or matched placebo (n = 40) for a period of 8 weeks. Efficacy measures were changes in the health-related quality of life (QoL) score (evaluated using the University of Washington index) and serum levels of a panel of mediators implicated in systemic inflammation including interleukins 6 (IL-6) and 8 (IL-8), TNF-α, transforming growth factor-β (TGFβ), high-sensitivity C-reactive protein (hs-CRP), calcitonin gene-related peptide (CGRP), substance P and monocyte chemotactic protein-1 (MCP-1). Curcuminoid supplementation was associated with a significantly greater improvement in QoL compared with placebo (p life variations were associated with changes in serum TGFβ levels in both correlation and regression analyses. Adjuvant therapy with a bioavailable curcuminoid preparation can significantly improve QoL and suppress systemic inflammation in patients with solid tumors who are under treatment with standard chemotherapy protocols.

    Adherence to adjuvant endocrine therapy (AET) for estrogen receptor-positive breast cancer remains suboptimal, which suggests that women are not getting the full benefit of the treatment to reduce breast cancer recurrence and mortality. The majority of studies on adherence to AET focus on identifying factors among those women at the highest levels of adherence and provide little insight on factors that influence medication use across the distribution of adherence. To understand how factors influence adherence among women across low and high levels of adherence. A retrospective evaluation was conducted using the Truven Health MarketScan Commercial Claims and Encounters Database from 2007-2011. Privately insured women aged 18-64 years who were recently diagnosed and treated for breast cancer and who initiated AET within 12 months of primary treatment were assessed. Adherence was measured as the proportion of days covered (PDC) over a 12-month period. Simultaneous multivariable quantile regression was used to assess the association between treatment and demographic factors, use of mail order pharmacies, medication switching, and out-of-pocket costs and adherence. The effect of each variable was examined at the 40th, 60th, 80th, and 95th quantiles. Among the 6,863 women in the cohort, mail order pharmacies had the greatest influence on adherence at the 40th quantile, associated with a 29.6% (95% CI = 22.2-37.0) higher PDC compared with retail pharmacies. Out-of-pocket cost for a 30-day supply of AET greater than $20 was associated with an 8.6% (95% CI = 2.8-14.4) lower PDC versus $0-$9.99. The main factors that influenced adherence at the 95th quantile were mail order pharmacies, associated with a 4.4% higher PDC (95% CI = 3.8-5.0) versus retail pharmacies, and switching AET medication 2 or more times, associated with a 5.6% lower PDC versus not switching (95% CI = 2.3-9.0). Factors associated with adherence differed across quantiles. Addressing the use of mail order

    2013-01-01

    The increasing use of patient-administered oral anticancer drugs is paralleled by new challenges in maintaining treatment adherence. These challenges are particularly significant with adjuvant therapies for prevention of disease recurrence, where the benefits of ongoing treatment are not readily apparent to patients. Nurse practitioners and physician assistants (collectively referred to as advanced practitioners) play integral roles in providing education on disease and treatment to patients that can increase adherence to oral therapies and ideally improve outcomes. For patients with gastrointestinal stromal tumor (GIST), the oral targeted therapy imatinib has become the mainstay of treatment for advanced and recurrent disease and as adjuvant therapy following surgical resection. Recent data indicate significantly improved overall survival with 3 years vs. 1 year of adjuvant imatinib therapy. Continuous dosing with imatinib is needed for optimal efficacy and to limit additional health-care costs associated with management of disease progression in GIST. However, longer duration of therapy increases the risk of nonadherence. Imatinib adherence rates, as well as factors contributing to nonadherence to adjuvant therapy in routine clinical practice, are discussed in this review. Also explored are practical approaches for improving adherence to adjuvant imatinib therapy through greater patient education, in light of the increased duration of therapy in select patients.

    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.

    Glycated chitosan (GC), a water soluble galactose-conjugated natural polysaccharide, has proven to be an effective immunoadjuvant for treatment of tumors based on laser thermal therapy. It was also shown to act as adjuvant for tumor therapy with high-intensity ultrasound and in situ photodynamic therapy (PDT). In the present study, GC was examined as potential adjuvant to PDT-generated cancer vaccine. Two other agents, pure calreticulin protein and acid ceramidase inhibitor LCL521, were also tested as prospective adjuvants for use in conjunction with PDT vaccines. Single treatment with GC, included with PDT vaccine cells suspension, improved the therapeutic efficacy when compared to vaccine alone. This attractive prospect of GC application remains to be carefully optimized and mechanistically elucidated. Both calreticulin and LCL521 proved also effective adjuvants when combined with PDT vaccine tumor treatment.

    Aromatase inhibitors are superior to tamoxifen as adjuvant therapy in postmenopausal patients with hormone-responsive breast cancer. We report the follow-up efficacy results from the N-SAS BC 03 trial (UMIN CTRID: C000000056) where anastrozole was compared with tamoxifen as adjuvant therapy in postmenopausal Japanese patients with hormone-responsive early breast cancer. The full analysis set contained 696 patients (anastrozole arm, n = 345; tamoxifen arm, n = 351). The log-rank test was used to compare the two groups in terms of disease-free survival (DFS) and relapse-free survival (RFS); Kaplan-Meier estimates were calculated. The treatment effects were estimated by Cox's proportional hazards model. To examine time-varying effect of hazard ratios, we estimated time-varying hazard ratios at time t [HR(t)] using data from time t up to 12 months. After a median follow-up of 98.5 months, hazard ratios (95% CIs) were 0.90 (0.65-1.24; log-rank p = 0.526) for DFS and 0.83 (0.56-1.23; log-rank p = 0.344) for RFS. Hazard ratios (95% CIs) for DFS and RFS up to 36 months were 0.69 (0.40-1.17) and 0.54 (0.27-1.06) and those after 36 months were 1.06 (0.70-1.59) and 1.05 (0.64-1.73), respectively. Time-varying hazard ratios for both DFS and RFS showed that hazard ratios were initially in favor of anastrozole and approached 1.0 at around 36 months. Superior efficacy of anastrozole to tamoxifen suggested by the initial analysis was not confirmed in the present analysis after a long-term follow-up period. Advantage of anastrozole was the greatest immediately after switching from tamoxifen and then decreased thereafter.

    Full Text Available BACKGROUND: Capecitabine is effective and indicated for the salvage treatment of metastatic breast cancer. Therefore, it is essential to evaluate the efficacy of capecitabine in the adjuvant setting. There have been two large randomized studies to determine whether patients with high-risk early breast cancer benefit from the addition of capecitabine to standard chemotherapy, but they have yielded inconsistent results. We first undertook a meta-analysis to evaluate the efficacy of the addition of capecitabine over standard treatment. METHODS: PubMed, EBSCO, Web of Science, conference proceedings and key trials were searched from 1998 to 2011. The hazard ratio (HR was used to evaluate the efficacy of a taxane-anthracycline regimen and a taxane-anthracycline-capecitabine regimen in early breast cancer. All of the data from each study use either fixed-effects or random-effects by Stata. FINDINGS: We found significant improvement in the additional capecitabine arm versus control in disease-free survival (DFS (HR = 0.83, 95% CI: 0.71-0.98, P = 0.027, overall survival (OS (HR = 0.71, 95% CI: 0.57-0.88, P = 0.002, distant recurrence (HR = 0.79, 95% CI: 0.66-0.94, P = 0.008 and the death from breast cancer only (HR = 0.65, 95% CI: 0.51-0.83, P = 0.001. Meanwhile, the subgroup analysis revealed that capecitabine improved the DFS in triple negative (HR = 0.71, 95% CI: 0.53-0.96, P = 0.028, hormone receptor negative (HR = 0.73, CI: 0.56-0.94, P = 0.017 and HER2 negative (HR = 0.81, CI: 0.67-0.98, P = 0.034 patients. CONCLUSION: Due to the synergistic effect of taxane and capecitabine, taxane-anthracycline-capecitabine regimen may effectively improve the efficacy in the adjuvant setting and may be a novel generation of adjuvant chemotherapy regimen. The results of the current meta-analysis support this hypothesis and indicate that taxane-based regimen with capecitabine may be an effective, convenient

    The majority of patients with cholangiocarcinoma present with advanced, irresectable tumours associated with poor prognosis. The incidence and mortality rates associated with cholangiocarcinoma continue to rise, mandating the development of novel strategies for early detection, improved resection and treatment of residual lesions. To review the current evidence base for surgical, adjuvant and neo-adjuvant techniques in the management of cholangiocarcinoma. A search strategy incorporating PubMed/Medline search engines and utilising the key words biliary tract carcinoma; cholangiocarcinoma; management; surgery; chemotherapy; radiotherapy; photodynamic therapy; and radiofrequency ablation, in various combinations, was employed. Data on neo-adjuvant and adjuvant techniques remain limited, and much of the literature concerns palliation of inoperable disease. The only opportunity for long-term survival remains surgical resection with negative pathological margins or liver transplantation, both of which remain possible in only a minority of selected patients. Neo-adjuvant and adjuvant techniques currently provide only limited success in improving survival. The development of novel strategies and treatment techniques is crucial. However, the shortage of randomised controlled trials is compounded by the low feasibility of conducting adequately powered trials in liver surgery, due to the large sample sizes that are required. © 2011 Blackwell Publishing Ltd.

    Locally recurring cervical cancer after surgery and adjuvant radiotherapy remains a major therapeutic challenge. This paper presents a new therapeutic technique for such patients: interstitial brachytherapy (BT) guided by real-time three-dimensional (3D) computed tomography (CT). Sixteen patients with recurrent cervical cancer after radical surgery and adjuvant external-beam radiotherapy (EBRT) were included in this study. These patients underwent high-dose-rate (HDR) interstitial BT with free-hand placement of metal needles guided by real-time 3D-CT. Six Gy in 6 fractions were prescribed for the high-risk clinical target volume (HR-CTV). D90 and D100 for HR-CTV of BT, and the cumulative D2cc for the bladder, rectum, and sigmoid, including previous EBRT and present BT were analyzed. Treatment-related complications and 3-month tumor-response rates were investigated. The mean D90 value for HR-CTV was 52.5 ± 3.3 Gy. The cumulative D2cc for the bladder, rectum, and sigmoid were 85.6 ± 5.8, 71.6 ± 6.4, and 69.6 ± 5.9 Gy, respectively. The mean number of needles was 6.1 ± 1.5, with an average depth of 3.5 ± 0.9 cm for each application. Interstitial BT was associated with minor complications and passable tumor-response rate. Interstitial BT guided by real-time 3D-CT for recurrent cervical cancer results in good dose-volume histogram (DVH) parameters. The current technique may be clinically feasible. However, long-term clinical outcomes should be further investigated.

    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. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.

    Long-term tamoxifen treatment significantly improves the survival of hormone receptor-positive (HR+) breast cancer (BC) patients. However, tamoxifen resistance remains a challenge. We aimed to identify prognostic biomarkers for tamoxifen resistance and reveal the underlying mechanism. From March 2001 to September 2013, 400 HR+ BC women (stage I~III) were treated with adjuvant tamoxifen for 5 years or until relapse in West China Hospital. We included a discovery set of 6 patients who were refractory to tamoxifen, and a validation cohort of 88 patients including 35 cases with relapse. In the discovery set, microRNA microarray showed that miR-4653-3p decreased in recurrent/metastatic lesions compared to the matched primary lesions. In the validation cohort, real-time RT-PCR demonstrated that, following tamoxifen treatment, miR-4653-3p overexpression in the primary tumors decreased the risk of relapse (adjusted hazard ratio [HR] = 0.17, 95% confidence interval [CI] = 0.05~0.57, P = 0.004). Conversely, high expression of FRS2, the key adaptor protein required by FGFR signaling, predicted poor disease-free survival (DFS) (adjusted HR = 2.70, 95% CI = 1.11~6.56, P = 0.03). MiR-4653-3p down regulated FRS2 by binding to its 3' untranslated region. Either overexpressing miR-4653-3p or attenuating FRS2 expression could restore TAM sensitivity in two tamoxifen-resistant BC cell lines. In conclusion, high miR-4653-3p level was the potential predictor for favorable DFS, while FRS2 overexpression was potential high-risk factor for relapse in HR+ BC patients receiving TAM adjuvant therapy. FGFR/FRS2 signaling might be a promising target for reversing tamoxifen resistance.

    Full Text Available Substantial controversy remains regarding the optimal adjuvant treatment for patients with resectable pancreatic adenocarcinoma. Despite improvements in radiation techniques, systemic therapies, and incorporation of targeted agents, the 5-year survival rates for early stage patients remains less than 25% and the optimal adjuvant treatment approach remains unclear. Here we summarize the data presented at the 2012 American Society of Clinical Oncology (ASCO Gastrointestinal Cancers Symposium regarding controversial issues surrounding the role, timing, and selection of patients for adjuvant chemoradiation strategies following curative resection for pancreatic adenocarcinoma.

    Qualitative comparative analysis (QCA) is a methodology created to address causal complexity in social sciences research by preserving the objectivity of quantitative data analysis without losing detail inherent in qualitative research. However, its use in health services research (HSR) is limited, and questions remain about its application in this context. To explore the strengths and weaknesses of using QCA for HSR. Using data from semistructured interviews conducted as part of a multiple case study about adjuvant treatment underuse among underserved breast cancer patients, findings were compared using qualitative approaches with and without QCA to identify strengths, challenges, and opportunities presented by QCA. Ninety administrative and clinical key informants interviewed across 10 NYC area safety net hospitals. Transcribed interviews were coded by 3 investigators using an iterative and interactive approach. Codes were calibrated for QCA, as well as examined using qualitative analysis without QCA. Relative to traditional qualitative analysis, QCA strengths include: (1) addressing causal complexity, (2) results presentation as pathways as opposed to a list, (3) identification of necessary conditions, (4) the option of fuzzy-set calibrations, and (5) QCA-specific parameters of fit that allow researchers to compare outcome pathways. Weaknesses include: (1) few guidelines and examples exist for calibrating interview data, (2) not designed to create predictive models, and (3) unidirectionality. Through its presentation of results as pathways, QCA can highlight factors most important for production of an outcome. This strength can yield unique benefits for HSR not available through other methods.

  13. Adjuvant therapy, not mammographic screening, accounts for most of the observed breast cancer specific mortality reductions in Australian women since the national screening program began in 1991.

    There has been a 28% reduction in age-standardised breast cancer mortality in Australia since 1991 when the free national mammographic program (BreastScreen) began. Therefore, a comparative study between BreastScreen participation and breast cancer age specific mortality trends in Australia was undertaken for two time periods between 1991 and 2007, where women aged 50-59 and 60-69 years, who were invited to screen, were compared to women aged 40-49 and 70-79 years who were not invited, but who did have access to the program. There were mortality reductions in all four age groups between 1991-1992 and 2007, resulting in 5,849 (95% CI 4,979 to 6,718) fewer women dying of breast cancer than would have otherwise been the case. Women aged 40-49 years, who had the lowest BreastScreen participation (approximately 20%), had the largest mortality reduction: 44% (95% CI 34.8-51.2). Women aged 60-69 years, who had the highest BreastScreen participation (approximately 60%), had the smallest mortality reduction: 19% (95% CI 10.5-26.9). As BreastScreen participation by invited women aged 50-69 years only reached a maximum of about 55-60% in 1998-1999, a decline in mortality in Australian women cannot be attributed to BreastScreen prior to this time. Thus, almost 60% of the Australian decline in breast cancer mortality since 1991 cannot be attributed to BreastScreen. Therefore, mammographic screening cannot account for most of the reductions in breast cancer mortality that have occurred in Australian women since 1991 and may have contributed to over-diagnosis. Most, if not all, of the reductions can be attributed to the adjuvant hormonal and chemotherapy, which Australian women have increasingly received since 1986.

    Pneumococcal meningitis is one of the most common infectious diseases of the central nervous system in pediatric period which is characterized by acute fever,unconvulsions,consciousness,in-creased intracranial pressure and meningeal irritation and cerebrospinal fluid pus changes in clinic. With the advent of antibiotics and pneumococcal vaccination,the morbidity and mortality of the disease decline signifi-cantly. But due to the appearance of drug-resistant bacteria and the relative lag of research and development speed of clinical new antibacterial drugs,it still has high mortality and morbidity which are promoting resear-ches of pathogenesis and adjuvant therapy. In this paper,researches of pathogenesis and adjuvant therapy for preumococcal meningitis were reviewed in recent years.%肺炎链球菌脑膜炎是小儿时期最常见的中枢神经系统感染性疾病之一,临床上以急性发热、惊厥、意识障碍、颅内压增高和脑膜刺激征及脑脊液脓性改变为特征。随着抗生素的应用及肺炎链球菌疫苗的接种,本病的发病率和病死率明显下降。但是耐药菌的不断出现和新的临床抗菌药物研发的相对滞后,其仍具有较高的病死率及致残率,这些均促进了针对肺炎链球菌脑膜炎发病机制及辅助治疗研究的不断深入。本文对近年来肺炎链球菌脑膜炎的发病机制及辅助治疗的研究进展作一综述。

    Patients with primary cutaneous melanomas that are ulcerated and >2 mm in thickness, >4 mm in thickness and those with nodal micrometastases at diagnosis, have few options for adjuvant treatment. Recent studies have suggested a role for vitamin D to delay melanoma recurrence and improve overall prognosis. This is a pilot placebo-controlled randomised phase II trial to assess the feasibility, safety and toxicity of an oral loading dose of Vitamin D (500,000 IU) followed by an oral dose of 50,000 IU of Vitamin D monthly for 2 years in patients who have been treated for cutaneous melanoma by wide excision of the primary. Patients aged 18-79 years who have completed primary surgical treatment and have Stage IIb, IIc, IIIa (N1a, N2a) or IIIb (N1a, N2a) disease are eligible for randomisation 2:1 to active treatment or placebo. The primary endpoints are sufficiency of dose, adherence to study medication and safety of the drug. The secondary endpoints are participation and progression free survival. The study has been approved by the Ethics Review Committee (RPAH Zone) of the Sydney Local Health District, protocol number X09-0138. Effective, non-toxic adjuvant therapy for high risk primary melanoma is not currently available. Favorable outcomes of this phase II study will form the basis for a multi-centre phase III study to assess whether the addition of oral high-dose vitamin D therapy in patients who have completed primary treatment for melanoma and are at high risk of recurrence will: 1. prolong time to recurrence within 5 years 2. improve overall survival at 5 years and 3. be both safe and tolerable. 62 patients have been randomised since the study commenced in December 2010. Target accrual for the study has been met with 75 patients randomised between December 2010 and August 2014.The Mel-D trial is conducted by the Australia and New Zealand Melanoma Trials Group (ANZMTG 02.09) TRIAL REGISTRATION: Australia and New Zealand Clinical Trials Registry (ANZCTR) ACTRN

    2013-07-01

    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.

    Clinical studies suggest that responses to HPV16 E6E7L2 fusion protein (TA-CIN) vaccination alone are modest, and GPI-0100 is a well-tolerated, potent adjuvant. Here we sought to optimize both the immunogenicity of TA-CIN via formulation with GPI-0100 and treatment of HPV16+ cancer by vaccination after cisplatin chemotherapy. HPV16 neutralizing serum antibody titers, CD4+ T cell proliferative and E6/E7-specific CD8+ T cell responses were significantly enhanced when mice were vaccinated subcutaneously (s.c.) or intramuscularly (i.m.) with TA-CIN formulated with GPI-0100. Vaccination was tested for therapy of mice bearing syngeneic HPV16 E6/E7+ tumors (TC-1) either in the lung or subcutaneously. Mice treated with TA-CIN/GPI-0100 vaccination exhibited robust E7-specific CD8+ T cell responses, which were associated with reduced tumor burden in the lung, whereas mice receiving either component alone were similar to controls. Since vaccination alone was not sufficient for cure, mice bearing s.c. TC-1 tumor were first treated with two doses of cisplatin and then vaccinated. Vaccination with TA-CIN/GPI-0100 i.m. substantially retarded tumor growth and extended survival after cisplatin therapy. Injection of TA-CIN alone, but not GPI-0100, into the tumor (i.t.) was similarly efficacious after cisplatin therapy, but the mice eventually succumbed. However, tumor regression and extended remission was observed in 80% of the mice treated with cisplatin and then intra-tumoral TA-CIN/GPI-0100 vaccination. These mice also exhibited robust E7-specific CD8+ T cell and HPV16 neutralizing antibody responses. Thus formulation of TA-CIN with GPI-0100 and intra-tumoral delivery after cisplatin treatment elicits potent therapeutic responses in a murine model of HPV16+ cancer.

    Purpose: The risk of cardiac injury with hypofractionated whole-breast/chest wall radiation therapy (HF-WBI) compared with conventional whole-breast/chest wall radiation therapy (CF-WBI) in women with left-sided breast cancer remains a concern. The purpose of this study was to determine if there is an increase in hospital-related morbidity from cardiac causes with HF-WBI relative to CF-WBI. Methods and Materials: Between 1990 and 1998, 5334 women ≤80 years of age with early-stage breast cancer were treated with postoperative radiation therapy to the breast or chest wall alone. A population-based database recorded baseline patient, tumor, and treatment factors. Hospital administrative records identified baseline cardiac risk factors and other comorbidities. Factors between radiation therapy groups were balanced using a propensity-score model. The first event of a hospital admission for cardiac causes after radiation therapy was determined from hospitalization records. Ten- and 15-year cumulative hospital-related cardiac morbidity after radiation therapy was estimated for left- and right-sided cases using a competing risk approach. Results: The median follow-up was 13.2 years. For left-sided cases, 485 women were treated with CF-WBI, and 2221 women were treated with HF-WBI. Mastectomy was more common in the HF-WBI group, whereas boost was more common in the CF-WBI group. The CF-WBI group had a higher prevalence of diabetes. The 15-year cumulative hospital-related morbidity from cardiac causes (95% confidence interval) was not different between the 2 radiation therapy regimens after propensity-score adjustment: 21% (19-22) with HF-WBI and 21% (17-25) with CF-WBI (P=.93). For right-sided cases, the 15-year cumulative hospital-related morbidity from cardiac causes was also similar between the radiation therapy groups (P=.76). Conclusions: There is no difference in morbidity leading to hospitalization from cardiac causes among women with left-sided early-stage breast

    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.

    Global control of tuberculosis (TB), an infectious disease that claims nearly 2 million lives annually, is hindered by the long duration of chemotherapy required for curative treatment. Lack of adherence to this intense treatment regimen leads to poor patient outcomes, development of new or additional drug resistance, and continued spread of M.tb. within communities. Hence, shortening the duration of TB therapy could increase drug adherence and cure in TB patients. Here, we report that additi...

    Extended use of antimycotics in oral candidiasis therapy gives rise to problems related to fungal drug resistance. The aim of this pilot study was to investigate the efficacy of tissue tolerable plasma (TTP) in denture stomatitis patients. It was hypothesised that (I): erythema and (IIa): complaint remission would be accelerated and (IIb): colony forming unit (CFU) reduction would be improved. The halves of the upper jaws of eight patients were randomly assigned to control (nystatin, chlorhexidine and placebo treatment) and test sides (nystatin, chlorhexidine and TTP administered six times each 7 days). The patients and the investigators, who were different from the therapists, were both blinded. Compared to the control sides, the erythema surface was reduced significantly more extensively on the test sides between 2 and 6 weeks of antifungal therapy (P ≤ 0.05). Visual analogue scale values and the frequency of moderate or heavy growth of Candida post-treatment did not differ significantly between both sides (P > 0.05). The primary hypothesis was confirmed, which may be interpreted as an accelerated remission. As drug therapy is usually limited to the time in which signs of infection are present, TTP might help reducing antifungal use. Even though the secondary hypotheses were not confirmed, persistence of Candida might be only colonisation.

    Purpose: In Radiation Therapy Oncology Group 9704, as previously published, patients with resected pancreatic adenocarcinoma received continuous infusion 5-FU and concurrent radiotherapy (5FU-RT). 5FU-RT treatment was preceded and followed by randomly assigned chemotherapy, either 5-FU or gemcitabine. This analysis explored whether failure to adhere to specified RT guidelines influenced survival and/or toxicity. Methods and Materials: RT requirements were protocol specified. Adherence was scored as per protocol (PP) or less than per protocol (therapy but before trial analysis and without knowledge of individual patient treatment outcomes. Scoring was done for all tumor locations and for the subset of pancreatic head location. Results: RT was scored for 416 patients: 216 PP and 200 adjuvant protocol for pancreatic adenocarcinoma to evaluate the impact of adherence to specified RT protocol guidelines on protocol outcomes. Failure to adhere to specified RT guidelines was associated with reduced survival and, for patients receiving gemcitabine, trend toward increased nonhematologic toxicity.

    Retrospective studies suggest that primary breast cancers lacking estrogen receptor (ER) and progesterone receptor (PR) and not overexpressing human epidermal growth factor receptor 2 (HER2; triple-negative tumors) are particularly sensitive to DNA-damaging chemotherapy with alkylating agents. Patients enrolled in International Breast Cancer Study Group Trials VIII and IX with node-negative, operable breast cancer and centrally assessed ER, PR, and HER2 were included (n = 2,257). The trials compared three or six courses of adjuvant classical cyclophosphamide, methotrexate, and fluorouracil (CMF) with or without endocrine therapy versus endocrine therapy alone. We explored patterns of recurrence by treatment according to three immunohistochemically defined tumor subtypes: triple negative, HER2 positive and endocrine receptor absent, and endocrine receptor present. Patients with triple-negative tumors (303 patients; 13%) were significantly more likely to have tumors > 2 cm and grade 3 compared with those in the HER2-positive, endocrine receptor-absent, and endocrine receptor-present subtypes. No clear chemotherapy benefit was observed in endocrine receptor-present disease (hazard ratio [HR], 0.90; 95% CI, 0.74 to 1.11). A statistically significantly greater benefit for chemotherapy versus no chemotherapy was observed in triple-negative breast cancer (HR, 0.46; 95% CI, 0.29 to 0.73; interaction P = .009 v endocrine receptor-present disease). The magnitude of the chemotherapy effect was lower in HER2-positive endocrine receptor-absent disease (HR, 0.58; 95% CI, 0.29 to 1.17; interaction P = .24 v endocrine receptor-present disease). The magnitude of benefit of CMF chemotherapy is largest in patients with triple-negative, node-negative breast cancer.

    幽门螺杆菌与多种胃肠道疾病相关,如消化性溃疡、慢性胃炎、胃黏膜相关淋巴瘤、胃癌等.目前随着传统三联方案及其他方案的广泛使用,幽门螺杆菌的耐药率越来越高,根除率日益下降.微生态制剂可以通过同幽门螺杆菌竞争结合位点、抑制幽门螺杆菌所致炎症反应、提高黏膜的免疫能力、产生抑制幽门螺杆菌物质、加强黏膜屏障功能等,抑制幽门螺杆菌的生长;同时可以减轻抗幽门螺杆菌治疗方案引起的不良反应,因此可安全地用于幽门螺杆菌感染的辅助治疗.%Helicobacter pylori are closely associated with various gastrointestinal diseases, such as peptic ulcer, chronic gastritis, gastric mucosal - associated lymphatic tissue lymphoma and gastric cancer. Recently, with triple therapy and other eradication regimens being widely used, the Helicobacter pylori resistance rates to antibiotics are getting higher, and the eradication efficacy is decreasing. Probiotics can inhibit the growth of Helicobacter pylori through binding the site in epithelial cells and restraining inflammation reaction induced by Helicobacter pylori, and it can improve the immune ability and barrier of mucosa, and can produce some substances that can inhibit Helicobacter pylori. Probiotics can also decrease the side effects of eradication regimens. Therefore, it can be safely used to adjuvant therapy for eradicating Helicobacter pylori.

    Non-adherence and non-persistence in breast cancer patients taking antihormonal therapy (AHT) is common. However, the complex patterns and dynamics of adherence and persistence are still not fully understood. This study aims to give insight into the process of (non-)adherence and (non-)persistence by researching influencing factors and their interrelatedness in breast cancer patients taking AHT by means of a qualitative study with semi-structured interviews. The sample consisted of 31 breast cancer patients treated with AHT. Purposive and theoretical sampling and the constant comparison method based on a grounded theory approach were used. Expectations regarding the impact of AHT, social support from family and friends, and recognition from healthcare professionals were found to influence the process of non-adherence and non-persistence. The results of this study can help healthcare professionals understand why breast cancer patients taking AHT do not always adhere to or persist in taking the therapy and may facilitate patient-tailored interventions. © 2015 John Wiley & Sons Ltd.

    Full Text Available Global control of tuberculosis (TB, an infectious disease that claims nearly 2 million lives annually, is hindered by the long duration of chemotherapy required for curative treatment. Lack of adherence to this intense treatment regimen leads to poor patient outcomes, development of new or additional drug resistance, and continued spread of M.tb. within communities. Hence, shortening the duration of TB therapy could increase drug adherence and cure in TB patients. Here, we report that addition of the United Stated Food and Drug Administration-approved phosphodiesterase inhibitors (PDE-Is cilostazol and sildenafil to the standard TB treatment regimen reduces tissue pathology, leads to faster bacterial clearance and shortens the time to lung sterilization by one month, compared to standard treatment alone, in a murine model of TB. Our data suggest that these PDE-Is could be repurposed for use as adjunctive drugs to shorten TB treatment in humans.

    Full Text Available PURPOSE: Previous studies have suggested that postmenopausal women with breast cancer who present with wild-type CYP2D6 may actually have similar or superior recurrence-free survival outcomes when given tamoxifen in place of aromatase inhibitors (AIs. The present study established a CYP2D6 multiple-genotype-based model to determine the optimal endocrine therapy for patients harboring wild-type CYP2D6. METHODS: We created a Markov model to determine whether tamoxifen or AIs maximized 5-year disease-free survival (DFS for extensive metabolizer (EM patients using annual hazard ratio (HR data from the BIG 1-98 trial. We then replicated the model by evaluating 9-year event-free survival (EFS using HR data from the ATAC trial. In addition, we employed two-way sensitivity analyses to explore the impact of HR of decreased-metabolizer (DM and its frequency on survival by studying a range of estimates. RESULTS: The 5-year DFS of tamoxifen-treated EM patients was 83.3%, which is similar to that of genotypically unselected patients who received an AI (83.7%. In the validation study, we further demonstrated that the 9-year EFS of tamoxifen-treated EM patients was 81.4%, which is higher than that of genotypically unselected patients receiving tamoxifen (78.4% and similar to that of patients receiving an AI (83.2%. Two-way sensitivity analyses demonstrated the robustness of the results. CONCLUSIONS: Our modeling analyses indicate that, among EM patients, the DFS/EFS outcome of patients receiving tamoxifen is similar to that of patients receiving an AI. Further prospective clinical trials are needed to evaluate the value of the CYP2D6 genotype in the selection of endocrine therapy.

  14. Carbohydrate-based immune adjuvants

    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

    Two hundred ninety-three patients were randomly assigned to three treatment regimens following mastectomy for operable but prognostically unfavorable breast cancer: L-PAM, CFP, or CFP with radiation therapy. For premenopausal patients an increased risk of recurrence was associated with the presence of unfavorable local signs, large number of lymph nodes involved, greater body weight, younger age, and L-PAM treatment. For the postmenopausal patients only three factors were associated with an increased risk of recurrent disease: large tumor size, large number of lymph nodes involved, and inner/central location of the primary lesion. Specifically, the treatment employed has shown no effect. Of particular importance is the fact that for neither group of patients does our experience presently demonstrate clear association of recurrent disease with the level of drug dose administered. Furthermore, evidence suggests that although patients who experience little or no myelosuppression have significantly worse disease-free intervals than patients who experience moderate or severe myelosuppression, here is no benefit for severe myelosuppression over moderate, myelosuppression.

    Shortening tuberculosis treatment could significantly improve patient adherence and decrease the development of drug resistance. Phosphodiesterase inhibitors (PDE-Is) have been shown to be beneficial in animal models of tuberculosis. We assessed the impact of PDE-Is on the duration of treatment in tuberculous mice. We analyzed the time to death in Mycobacterium tuberculosis-infected mice receiving type 4 PDE-Is (rolipram and cilomilast) and the impact on bacterial burden, time to clearance, and relapse when types 3 and 5 PDE-Is (cilostazol and sildenafil, respectively) and rolipram were added to the standard treatment. We investigated pharmacokinetic interactions between PDE-Is (cilostazol and sildenafil) and rifampin. The type 4 PDE-Is rolipram and cilomilast accelerated the time to death in tuberculous mice. The addition of rolipram to standard tuberculosis treatment increased bacterial burden and did not decrease the time to bacterial clearance in the lung, while the addition of the cilostazol and sildenafil reduced the time to clearance by 1 month. Cilostazol and sildenafil did not have negative pharmacokinetic interactions with rifampin. Type 4 PDE-Is may increase the severity of tuberculosis and should be carefully investigated for use in patients with latent or active tuberculosis. Cilostazol and sildenafil may benefit tuberculosis patients by shortening the duration of therapy.

    Full Text Available Abstract Background To report about initial technical and clinical experience in preoperative radiation treatment of rectal cancer with volumetric modulated arcs with the RapidArc® (RA technology. Methods Twenty-five consecutive patients (pts were treated with RA. All showed locally advanced rectal adenocarcinoma with stage T2-T4, N0-1. Dose prescription was 44 Gy in 22 fractions (or 45 Gy in 25 fractions. Delivery was performed with single arc with a 6 MV photon beam. Twenty patients were treated preoperatively, five did not receive surgery. Twenty-three patients received concomitant chemotherapy with oral capecitabine. A comparison with a cohort of twenty patients with similar characteristics treated with conformal therapy (3DC is presented as well. Results From a dosimetric point of view, RA improved conformality of doses (CI95% = 1.1 vs. 1.4 for RA and 3DC, presented similar target coverage with lower maximum doses, significant sparing of femurs and significant reduction of integral and mean dose to healthy tissue. From the clinical point of view, surgical reports resulted in a down-staging in 41% of cases. Acute toxicity was limited to Grade 1-2 diarrhoea in 40% and Grade 3 in 8% of RA pts, 45% and 5% of 3DC pts, compatible with known effects of concomitant chemotherapy. RA treatments were performed with an average of 2.0 vs. 3.4 min of 3DC. Conclusion RA proved to be a safe, qualitatively advantageous treatment modality for rectal cancer, showing some improved results in dosimetric aspects.

    Purpose In RTOG 9704, as previously published, patients with resected pancreatic adenocarcinoma received continuous infusion 5-FU and concurrent radiotherapy (5FU-RT). 5FU-RT treatment was preceded and followed by randomly assigned chemotherapy, either 5-FU or gemcitabine. This analysis explored whether failure to adhere to specified RT guidelines influenced survival and/or toxicity. Methods and Materials RT requirements were protocol specified. Adherence was scored as per protocol (PP) or less than per protocol (therapy but prior to trial analysis and without knowledge of individual patient treatment outcomes. Scoring was done for all tumor locations and for the subset of pancreatic head location. Results RT was scored for 416 patients: 216 PP and 200 adjuvant protocol for pancreatic adenocarcinoma to evaluate the impact of adherence to specified RT protocol guidelines on protocol outcomes. Failure to adhere to specified RT guidelines was associated with reduced survival and, for patients receiving gemcitabine, trend toward increased non-hematologic toxicity. PMID:21277694

    We evaluated the efficacy of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine in preventing HPV-related disease after surgery for cervical lesions in a post-hoc analysis of the PApilloma TRIal against Cancer In young Adults (PATRICIA; NCT00122681). Healthy women aged 15-25 years were randomized (1:1) to receive vaccine or control at months 0, 1 and 6 and followed for 4 years. Women were enrolled regardless of their baseline HPV DNA status, HPV-16/18 serostatus, or cytology, but excluded if they had previous or planned colposcopy. The primary and secondary endpoints of PATRICIA have been reported previously; the present post-hoc analysis evaluated efficacy in a subset of women who underwent an excisional procedure for cervical lesions after vaccination. The main outcome was the incidence of subsequent HPV-related cervical intraepithelial neoplasia grade 2 or greater (CIN2+) 60 days or more post-surgery. Other outcomes included the incidence of HPV-related CIN1+, and vulvar or vaginal intraepithelial neoplasia (VIN/VaIN) 60 days or more post-surgery. Of the total vaccinated cohort of 18,644 women (vaccine = 9,319; control = 9,325), 454 (vaccine = 190, control = 264) underwent an excisional procedure during the trial. Efficacy 60 days or more post-surgery for a first lesion, irrespective of HPV DNA results, was 88.2% (95% CI: 14.8, 99.7) against CIN2+ and 42.6% (-21.1, 74.1) against CIN1+. No VIN was reported and one woman in each group had VaIN2+ 60 days or more post-surgery. Women who undergo surgical therapy for cervical lesions after vaccination with the HPV-16/18 vaccine may continue to benefit from vaccination, with a reduced risk of developing subsequent CIN2+. © 2016 UICC.

    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

    Full Text Available Cytotoxic agents are a main part of therapeutic process against the observed tumors, which lead to some unwished damages, due to drug uptake by normal body cells causing various tissue/organ failures associated with formal administration manners. But nowadays the risk is reduced by new target therapy techniques, of which the observed physical nature of micelles and nanosilver particles, governing their special behavior, could help using micelle-coated silver nanoparticles as a novel adjuvant for cancer target therapy.

    Purpose Human epidermal growth factor receptor 2 (HER2)-positive/hormone receptor (HR)-positive breast cancer is a distinct subgroup associated with lower chemotherapy sensitivity and slightly better outcome than HER2-positive/HR-negative disease. Little is known about the efficacy of the combination of endocrine therapy (ET) with trastuzumab or with the potent antibody-cytotoxic, anti-HER2 compound trastuzumab emtansine (T-DM1) with or without ET for this subgroup. The West German Study Group trial, ADAPT (Adjuvant Dynamic Marker-Adjusted Personalized Therapy Trial Optimizing Risk Assessment and Therapy Response Prediction in Early Breast Cancer) compares pathologic complete response (pCR) rates of T-DM1 versus trastuzumab with ET in early HER2-positive/HR-positive breast cancer. Patients and Methods In this prospective, neoadjuvant, phase II trial, 375 patients with early breast cancer with HER2-positive and HR-positive status (n = 463 screened) were randomly assigned to 12 weeks of T-DM1 with or without ET or to trastuzumab with ET. The primary end point was pCR (ypT0/is/ypN0). Early response was assessed in 3-week post-therapeutic core biopsies (proliferation decrease ≥ 30% Ki-67 or cellularity response). Secondary end points included safety and predictive impact of early response on pCR. Adjuvant therapy followed national standards. Results Baseline characteristics were well balanced among the arms. More than 90% of patients completed the therapy per protocol. pCR was observed in 41.0% of patients treated with T-DM1, 41.5% of patients treated with T-DM1 and ET, and 15.1% with trastuzumab and ET ( P < .001). Early responders (67% of patients with assessable response) achieved pCR in 35.7% compared with 19.8% in nonresponders (odds ratio, 2.2; 95% CI, 1.24 to 4.19). T-DM1 was associated with a significantly higher prevalence of grade 1 to 2 toxicities, especially thrombocytopenia, nausea, and elevation of liver enzymes. Overall toxicity was low; seventeen

    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.

    Approximately 13% of women diagnosed with endometrial cancer present with advanced stage disease (International Federation of Gynecology and Obstetrics (FIGO) stage III/IV). The standard treatment of advanced endometrial cancer consists of cytoreductive surgery followed by radiation therapy, or chemotherapy, or both. There is currently little agreement about which adjuvant treatment is the safest and most effective. To evaluate the effectiveness and safety of adjuvant chemotherapy compared with radiotherapy or chemoradiation, and to determine which chemotherapy agents are most effective in women presenting with advanced endometrial cancer (FIGO stage III/IV). We searched the Cochrane Gynaecological Cancer Collaborative Review Group's Trial Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 10 2013), MEDLINE and EMBASE up to November 2013. Also we searched electronic clinical trial registries for ongoing trials. Randomised controlled trials (RCTs) of adjuvant chemotherapy compared with radiotherapy or chemoradiation in women with FIGO stage III and IV endometrial cancer. Two review authors selected trials, extracted data, and assessed trials for risk of bias. Where necessary, we contacted trial investigators for relevant, unpublished data. We pooled data using the random-effects model in Review Manager (RevMan) software. We included four multicentre RCTs involving 1269 women with primary FIGO stage III/IV endometrial cancer. We considered the trials to be at low to moderate risk of bias. All participants received primary cytoreductive surgery. Two trials, evaluating 620 women (83% stage III, 17% stage IV), compared adjuvant chemotherapy with adjuvant radiotherapy; one trial evaluating 552 women (88% stage III, 12% stage IV) compared two chemotherapy regimens (cisplatin/doxorubicin/paclitaxel (CDP) versus cisplatin/doxorubicin (CD) treatment) in women who had all undergone adjuvant radiotherapy; and one trial contributed no data

    Objective: To review the results of adjuvant external beam radiation therapy (EBRT) combined with high-dose rate brachytherapy (HDR-BT) for the treatment of endometrial carcinoma. Materials and methods: We retrospectively evaluated 141 patients treated with EBRT and HDR-BT after surgery between January 1993 and January 2001. EBRT was performed with a median dose of 45 Gy, and HDR-BT was performed with a median dose of 24 Gy, with four weekly insertions of 6 Gy. The median age of the patients was 63 years and the disease stage distribution was: CS I (FIGO), 52.4%; CS II, 13.5%; CS III, 29.8%; CS IV, 4.3%. Results: With a median follow-up of 53.7 months, the disease free survival (DFS) at five years was: CS I, 88.0%; CS II, 70.8%; CS III, 55.1%; CS IV, 50.0% (p = 0.0003). Global survival after five years was: CS I, 79.6%; CS II, 74.0%; CS III, 53.6%; CS IV, 100.0% (p = 0.0062). Factors affecting the DFS were histological grade and serous-papillary histology. Recurrence of the disease was observed in 33 cases, 13 (9.2%) of these occurred in the pelvis, vagina or vaginal vault. EBRT + HDR-BT of the vaginal vault allowed disease control in 90.8% of the cases. Conclusion: Radiation therapy is essential for loco-regional control of endometrial cancer and can achieve excellent cure rates in the initial stages. In more advanced stages, therapeutic failure frequently appears as distant metastases suggesting the need for complementary systemic therapy using new treatment modalities, particularly chemotherapy.

  20. 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.

The accepted strategies for adjuvant AI therapy include initial adjuvant treatment following surgery, switching and/or sequencing from prior tamoxifen, and extended adjuvant therapy following the full 5 years of tamoxifen treatment. Among the available AIs, letrozole has been evaluated in large, well-controlled, double-blind clinical trials in the initial adjuvant, extended adjuvant, and more recently, the sequential adjuvant settings. Letrozole is the most potent of the AIs and provides near complete suppression of plasma estrogens in PMW. Letrozole also significantly reduces the occurrence of early distant metastases, the most lethal type of recurrence event, which can lead to improved survival. Clinical comparisons of letrozole with both tamoxifen and placebo have also provided important long-term safety data on the use of AIs as adjuvant therapy in PMW with EBC. The weight of clinical evidence indicates that letrozole is a safe and effective option for adjuvant hormonal therapy across all three AI treatment settings.Keywords: aromatase inhibitor, breast cancer, hormonal therapy, letrozole, postmenopausal women, tamoxifen

    The indication of adjuvant chemotherapy for patients with highly proliferative estrogen receptor-positive breast cancer is controversial. We analyzed the predictive value of Ki67 for the efficacy of adjuvant chemotherapy in patients with estrogen receptor-positive, node-positive breast cancer. We identified 1241 patients with Luminal B early stage breast cancer with 1-3 axillary positive nodes who underwent surgery between 1995 and 2005 at the European Institute of Oncology and received adjuvant hormonotherapy and/or chemotherapy. Differences in the distribution of characteristics according to treatment were evaluated by the Chi-square test. To evaluate the effect of adding chemotherapy to hormonotherapy, the propensity score method was used to match patients' characteristics minimizing bias related to the non-random assignment of treatment. The probability of receiving chemotherapy was significantly associated with age, tumor grade, degree of hormone responsiveness, tumor size and peripheral vascular invasion. The propensity score distribution was statistically different between the two treatment groups (p value 0.663). The 5-year DFS percentages were 84.6% (95% CI, 81.0-87.6%) in the hormonotherapy group and 84.2% (95% CI, 81.3-86.7%) in the hormonotherapy/chemotherapy group (log-rank test p-value 0.388). However, when analyzing the 5-year DFS by Ki-67 distribution, Subpopulation Treatment Effect Pattern Plot (STEPP) analysis showed a beneficial effect of chemotherapy in patients with highly proliferative tumor (Ki-67 ≥ 32%). The interaction between Ki-67 and treatment was statistically significant (p = 0.027). Ki67 expression identifies a subset of patients with Luminal B and node-positive breast cancer who could benefit from addition of adjuvant chemotherapy to hormonotherapy. Dichotomy was observed for Ki67 at 32% level. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Over the last decade, there has been a flurry of research on adjuvants for vaccines, and several novel adjuvants are now in licensed products or in late stage clinical development. The success of adjuvants in enhancing the immune response to recombinant antigens has led many researchers to re-focus their vaccine development programs. Successful vaccine development requires knowing which adjuvants to use and knowing how to formulate adjuvants and antigens to achieve stable, safe and immunogenic vaccines. For the majority of vaccine researchers this information is not readily available, nor is access to well-characterized adjuvants. In this review, we outline the current state of adjuvant research and development and how formulation parameters can influence the effectiveness of adjuvants.

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

  6. A Review and Prospect on Herbicide Adjuvants

    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.

    During the last decades, the conventional therapy for autoimmune blistering diseases has been high-dose, long-term systemic corticosteroid and immunosuppressive agents or adjuvant drugs. Long-term, high-dose steroid therapy can result in serious adverse effects. The rationale for using adjuvant drugs is that concerns reducing the need for corticosteroids, and hence, their side effects, or it may result in better control of the disease, or both. Immunosuppressive agents are not free of adverse effects, however. Prolonged immune suppression may account for high rates of morbidity, disability, and possible death. There is no consensus about the first-choice adjuvant drug for the management of blistering autoimmune diseases. This contribution evaluates six adjuvant drugs-cyclophosphamide, azathioprine, cyclosporine, mycophenolate mofetil, intravenous immunoglobulin, and rituximab-and discusses the choice of a "winning drug" that is effective and safe.

    Adjuvant treatment options for Stage I seminoma include active surveillance, chemotherapy, and radiotherapy. Active surveillance may not be ideal for the average Indian patient. Of the two accepted adjuvant therapy options, namely single-dose carboplatin chemotherapy and radiotherapy to the retroperitoneal nodes, though it intuitively appears more appealing, a deeper review reveals the potential drawbacks of chemotherapy. This article highlights the misconceptions regarding carboplatin and provides reasons for an argument why radiotherapy is better when a patient with Stage I seminoma chooses to undergo adjuvant treatment.

    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.

    It is unclear how noncancer conditions affect the use or effectiveness of adjuvant therapy among older patients with colon cancer. The authors conducted a cohort study of older patients with stage III colon cancer who were diagnosed from 1993 to 1999 in the Surveillance, Epidemiology, and End Results-Medicare database. The correlations between receipt of adjuvant chemotherapy and heart failure, diabetes, and chronic obstructive pulmonary disease (COPD) were assessed. Multivariable regression analysis was used to assess the risk of death and hospitalization as a function of treatment and comorbidity status. The study sample consisted of 5330 patients (median age, 76 years). The use of adjuvant therapy was related significantly to heart failure (36.2% vs 64.9% of patients with vs without heart failure, respectively; adjusted odds ratio [OR], 0.49; 95% confidence interval [95% CI], 0.40-0.60). More moderate correlations were observed for COPD (OR, 0.83; 95% CI, 0.70-0.99) and diabetes (OR, 0.81; 95% CI, 0.68-0.97). Among patients who had heart failure, the 5-year survival was significantly higher among those who received adjuvant chemotherapy (adjusted 5-year survival rate, 43%; 95% CI, 40-47%) than among those who did not receive adjuvant chemotherapy (30%; 95% CI, 27-34%). Among patients without heart failure, the 5-year survival estimates among treated and untreated patients were 54% (95% CI, 52-56%) and 41% (95% CI, 38-44%), respectively. The probability of all-cause, condition-specific, or toxicity-related hospitalization associated with adjuvant therapy was not altered by the presence of any of the 3 conditions. Although chronic conditions appeared to be a strong barrier to the receipt of adjuvant chemotherapy, adjuvant therapy appeared to provide a significant survival benefit to patients who had colon cancer with the conditions studied.

    2012-06-01

    The pediatric loco-regional techniques are considered very safe and effective, first of all because they target the therapy directly to the site of surgery, decreasing the risks of intravenous analgesia. The quality of local anesthesia is influenced by structural and biophysical characteristics of local anesthetics drug, dose, site of injection, mixture of local anesthetics and possible addition of a vasoconstrictor or an adjuvant to prolong the analgesic effect. In children, unlike adults, small nerve diameters and short distance between Ranvier nodes permit to use large volumes and low concentrations of local anesthetics. The clinical practice has shown that in pediatric population, effective analgesia is obtained by 1% mepivacaine, 1% lidocaine and 0.25% bupivacaine or better 0.2% ropivacaine, 0.2-0.25% levobupivacaine. In addition, levobupivacaine and ropivacaine have a better profile in terms of safety in comparison to bupivacaine and are the local anesthetics of choice for the daily clinical practice also in children as in adults. Among the adjuvant, clonidine and ketamine showed the best pharmacokinetic and pharmacodynamic profiles of effective and safety, improving and prolonging the action of associated local anesthetics. Therefore, the use of enantiomers, in association with adjuvants as clonidine or ketamine, using the multimodal approach of integrated anesthesia, makes the clinical practice effective and safe in the pediatric operating rooms. This review focuses on the overview of local anesthetics and adjuvants used today in locoregional pediatric anesthesia, with an emphasis on the advantages and disadvantages of each drug.

    Background Endometrial adenocarcinoma (womb cancer) is a malignant growth of the lining (endometrium) of the womb (uterus). It is distinct from sarcomas (tumours of the uterine muscle). Survival depends the risk of microscopic metastases after surgery. Adjuvant (postoperative) chemotherapy improves survival from some other adenocarcinomas, and there is evidence that endometrial cancer is sensitive to cytotoxic therapy. This systematic review examines the effect of chemotherapy on survival after hysterectomy for endometrial cancer. Objectives To assess efficacy of adjuvant (postoperative) chemotherapy for endometrial cancer. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2010, Issue 3), MEDLINE and EMBASE up to August 2010, registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. Selection criteria Randomised controlled trials (RCTs) comparing adjuvant chemotherapy with any other adjuvant treatment or no other treatment. Data collection and analysis We used a random-effects meta-analysis to assess hazard ratios (HR) for overall and progression-free survival and risk ratios (RR) to compare death rates and site of initial relapse. Main results Five RCTs compared no additional treatment with additional chemotherapy after hysterectomy and radiotherapy. Four trials compared platinum based combination chemotherapy directly with radiotherapy. Indiscriminate pooling of survival data from 2197 women shows a significant overall survival advantage from adjuvant chemotherapy (RR (95% CI) = 0.88 (0.79 to 0.99)). Sensitivity analysis focused on trials of modern platinum based chemotherapy regimens and found the relative risk of death to be 0.85 ((0.76 to 0.96); number needed to treat for an additional beneficial outcome (NNT) = 25; absolute risk reduction = 4% (1% to 8%)). The HR for overall survival is 0.74 (0.64 to 0.89), significantly

    Sub-cutaneous immunotherapy is an effective treatment for allergy. It works by helping to modify or re-balance an individual's immune response to allergens and its efficacy is greatly improved by the use of adjuvants, most commonly, aluminium hydroxide. Aluminium salts have been used in allergy therapy for many decades and are assumed to be safe with few established side-effects. This assumption belies their potency as adjuvants and their potential for biological reactivity both at injection sites and elsewhere in the body. There are very few data purporting to the safety of aluminium adjuvants in allergy immunotherapy and particularly so in relation to longer term health effects. There are, if only few, published reports of adverse events following allergy immunotherapy and aluminium adjuvants are the prime suspects in the majority of such incidents. Aluminium adjuvants are clearly capable of initiating unwanted side effects in recipients of immunotherapy and while there is as yet no evidence that such are commonplace it is complacent to consider aluminium salts as harmless constituents of allergy therapies. Future research should establish the safety of the use of aluminium adjuvants in sub-cutaneous allergy immunotherapy.

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

    2017-02-17

    As the rates of systemic fungal infections continue to rise and antifungal drug resistance becomes more prevalent, there is an urgent need for new therapeutic options. This issue is exacerbated by the limited number of systemic antifungal drug classes. However, the discovery, development, and approval of novel antifungals is an extensive process that often takes decades. For this reason, there is growing interest and research into the possibility of combining existing therapies with various adjuvants that either enhance activity or overcome existing mechanisms of resistance. Reports of antifungal adjuvants range from plant extracts to repurposed compounds, to synthetic peptides. This approach would potentially prolong the utility of currently approved antifungals and mitigate the ongoing development of resistance.

    Adjuvant therapy for colorectal cancer (CRC) in patients aged ≥75 years is supported by inadequate evidence, although such patients are increasing in number worldwide. We assessed the influence of age and comorbidities on the prognosis of CRC in elderly patients using pooled data by the Japanese Study Group for Postoperative Follow-up of Colorectal Cancer. In total, 4598 patients (3304 with colon cancer and 1294 with rectal cancer) who underwent curative surgery from 2004 to 2006 were analysed with respect to age, Charlson comorbidity score (CS), tumour marker positivity, adjuvant therapy and prognosis. The number of patients aged 75 years was 2007 (44%), 1614 (35%) and 977 (21%), respectively. Tumour location, tumour marker positivity, clinical stage, performance of adjuvant therapy, CS and overall survival (OS) were significantly different among these age groups (P cancer and 21% with rectal cancer received adjuvant therapy; these proportions were much lower than those in younger patients. Application of adjuvant therapy was dependent on the CS in patients aged ≤74 years, but not in older patients. Sex, the carcinoembryonic antigen concentration and adjuvant therapy were significantly associated with OS in elderly patients with stage III CRC. Age and comorbidities worsened the OS of patients with CRC who underwent curative surgery. However, patients aged ≥75 years were undertreated regardless of their CS despite the possibility of OS improvement by adjuvant therapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. Oncologist use of the Adjuvant! model for risk communication: a pilot study examining patient knowledge of 10-year prognosis

    2009-04-01

    Full Text Available Abstract Background Our purpose was to collect preliminary data on newly diagnosed breast cancer patient knowledge of prognosis before and after oncology visits. Many oncologists use a validated prognostic software model, Adjuvant!, to estimate 10-year recurrence and mortality outcomes for breast cancer local and adjuvant therapy. Some oncologists are printing Adjuvant! screens to use as visual aids during consultations. No study has reported how such use of Adjuvant! printouts affects patient knowledge of prognosis. We hypothesized that Adjuvant! printouts would be associated with significant changes in the proportion of patients with accurate understanding of local therapy prognosis. Methods We recruited a convenience sample of 20 patients seen by 2 senior oncologists using Adjuvant! printouts of recurrence and mortality screens in our academic medical center. We asked patients for their estimates of local therapy recurrence and mortality risks and counted the number of patients whose estimates were within ± 5% of Adjuvant! before and after the oncology visit, testing whether pre/post changes were significant using McNemar's two-sided test at a significance level of 5%. Results Two patients (10% accurately estimated local therapy recurrence and mortality risks before the oncology visit, while seven out of twenty (35% were accurate afterwards (p = 0.125. Conclusion A majority of patients in our sample were inaccurate in estimating their local therapy recurrence and mortality risks, even after being shown printouts summarizing these risks during their oncology visits. Larger studies are needed to replicate or repudiate these preliminary findings, and test alternative methods of presenting risk estimates. Meanwhile, oncologists should be wary of relying exclusively on Adjuvant! printouts to communicate local therapy recurrence and mortality estimates to patients, as they may leave a majority of patients misinformed.

    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

    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.

    2012-01-01

    Adjuvants enhance immunity to vaccines and experimental antigens by a variety of mechanisms. In the past decade, many receptors and signaling pathways in the innate immune system have been defined and these innate responses strongly influence the adaptive immune response. The focus of this review is to delineate the innate mechanisms by which adjuvants mediate their effects. We highlight how adjuvants can be used to influence the magnitude and alter the quality of the adaptive response in order to provide maximum protection against specific pathogens. Despite the impressive success of currently approved adjuvants for generating immunity to viral and bacterial infections, there remains a need for improved adjuvants that enhance protective antibody responses, especially in populations that respond poorly to current vaccines. However, the larger challenge is to develop vaccines that generate strong T cell immunity with purified or recombinant vaccine antigens. PMID:21029960

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

    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.

    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

    2015-03-24

    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.

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

    2013-11-01

    Recurrent respiratory papillomatosis (RRP) in young children is frequently characterized by a recalcitrant course and need for multiple surgeries. Periodic surgical debulking and ablation is the mainstay of therapy as a cure for RRP rarely occurs. Benefits of adjuvant treatment with local injection of cidofovir in aggressive cases of RRP have been reported in both children and adults. However, a consensus on initiation, dosage, or scheduling of this drug has not been established in the very young patient. Literature on successful remission in children less than 1 year of age is not available. One such case of an infant with aggressive RRP treated with local adjuvant cidofovir is described herein.

    2011-10-01

    The International Breast Cancer Study Group Trial VIII compared long-term efficacy of endocrine therapy (goserelin), chemotherapy [cyclophosphamide, methotrexate and fluorouracil (CMF)], and chemoendocrine therapy (CMF followed by goserelin) for pre/perimenopausal women with lymph-node-negative breast cancer. From 1990 to 1999, 1063 patients were randomized to receive (i) goserelin for 24 months (n = 346), (ii) six courses of 'classical' CMF (cyclophosphamide, methotrexate, 5-fluorouracil) chemotherapy (n = 360), or (iii) six courses of CMF plus 18 months goserelin (CMF→ goserelin; n = 357). Tumors were classified as estrogen receptor (ER) negative (19%), ER positive (80%), or ER unknown (1%); 19% of patients were younger than 40. Median follow-up was 12.1 years. For the ER-positive cohort, sequential therapy provided a statistically significant benefit in disease-free survival (DFS) (12-year DFS = 77%) compared with CMF alone (69%) and goserelin alone (68%) (P = 0.04 for each comparison), due largely to the effect in younger patients. Patients with ER-negative tumors whose treatment included CMF had similar DFS (12-year DFS CMF = 67%; 12-year DFS CMF→ goserelin = 69%) compared with goserelin alone (12-year DFS = 61%, P= NS). For pre/perimenopausal women with lymph-node-negative ER-positive breast cancer, CMF followed by goserelin improved DFS in comparison with either modality alone. The improvement was the most pronounced in those aged below 40, suggesting an endocrine effect of prolonged CMF-induced amenorrhea.

  5. MYST3/CREBBP Rearranged Acute Myeloid Leukemia after Adjuvant Chemotherapy for Breast Cancer

    Directory of Open Access Journals (Sweden)

    Arjun Gupta

    2014-01-01

    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.

    2012-01-01

    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.

    2011-12-01

    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.

  8. Applications of nanomaterials as vaccine adjuvants.

    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.

    To analyze the impact of adjuvant radiation therapy (RT) on overall survival (OS) and disease-specific survival (DSS) in patients with verrucous carcinoma (VC) as compared to squamous cell carcinoma (SCC) of the oral cavity. Cross-sectional population analysis. Cases of nonmetastatic VC/SCC of the oral cavity were extracted from the Surveillance, Epidemiology, and End Results (SEER) database (1988-2013). Kaplan-Meier survivals, stratified according to T stage, were compared between VC and SCC for treatment with or without adjuvant RT. A total of 18,819 VC/SCC cases were identified. There were 581 (3.1%) VC (mean age 69.6 years, 48.9% female) versus 18,238 (97.0%) SCC (mean age, 65.3, 37.1% female) patients. Verrucous carcinoma patients receiving surgery alone (N = 539) demonstrated a trend toward improved OS versus VC patients receiving surgery and RT (N = 40) (117.0 vs. 71.4 months, respectively, P = 0.119). There was a statistically significant improvement in DSS in VC patients receiving surgery alone (217.2 vs. 110.9 months, P = 0.05). Verrucous carcinoma patients treated with adjuvant RT demonstrated a trend toward a worse OS (71.4 vs. 93.0 months, P = 0.992) and DSS (110.9 vs. 162.3 months, P = 0.275) compared to SCC tre
