HPV-associated second primary tumors may present as synchronous and/or metachronous lesions and can arise outside the oropharynx after prolonged intervals. Further work is necessary to identify patients at risk and to elucidate the mechanisms of HPV-associated head and neck second primary tumors.
Background:Trastuzumab was approved in the United Kingdom for adjuvant treatment of human epidermal growth factor receptor 2 (HER2)+ breast cancer in 2006 at significant economic cost and with limited evidence in smaller T1N0 tumours. The South East Wales Cancer Network covers a population of 1 420 000 and maintains a database of treatments used. We examined this database to ensure the outcome of Trastuzumab use is as expected, especially in patients with T1N0 cancers.Ethods:M Case notes of patients with HER2+ disease eligible for adjuvant Trastuzumab over 2005–2008 were reviewed. Disease-free survival (DFS) and overall survival (OS) were calculated with the Kaplan–Meier method using SPSS (version 16.0.01 for Windows, SPSS, Chicago, IL, USA).Results:A total of 239 of 338 (70.7%) eligible HER2+ patients received treatment. At 3 years, the DFS of the treated group was 90.3% vs 73.3% and the OS was 98.5% vs 87.6%. In all, 47 of 92 stage I patients received Trastuzumab. Despite a trend towards worse prognostic factors in the treated group the DFS was 100% vs 84.1% and the OS was 100% vs 93.3%.Conclusion:Our results are comparable to those from landmark Trastuzumab trials. As evidence continues to emerge that smaller HER2+ cancers may behave aggressively our analysis of stage I tumours adds further support to the use of Trastuzumab in these patients.
Patients with de novo metastatic prostate cancer are primarily treated with androgen deprivation with very high (>95%) response rates, but all patients eventually develop castrate-refractory prostate cancer, which has a poor prognosis. Accumulating evidence suggests that continued androgen receptor signaling remains critical for survival and growth, with adrenal and intratumoral sources of androgens contributing to disease activation. Abiraterone acetate is a novel androgen biosynthesis inhibitor that has been shown to improve survival for patients with metastatic castrate-refractory prostate cancer who have progressed on docetaxel chemotherapy. It is a well-tolerated orally administered drug with a low incidence of serious side effects, taken with prednisone to reduce the secondary effects of mineralocorticoid excess. In the chemo-naive population, a recent trial has also shown improved outcomes, and ongoing studies are investigating its role even earlier in the disease course and in combination with other drugs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
