BACKGROUND ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) may have anti-tumor properties. We investigated whether the use of ACEI/ARBs affects the clinical outcomes of primary breast cancer patients receiving taxane and anthracycline-based neoadjuvant chemotherapy. METHODS We included 1449 patients with diagnosis of invasive primary(More)
Treatment for anaplastic astrocytoma (AA) is controversial. To assess three primary treatment approaches, patients from a single institution were retrospectively evaluated. To represent modern treatment selection, patients diagnosed with AA from December 2003 to December 2009 were selected. Those with insufficient data, incomplete pathology, and(More)
Primary cerebellar glioblastoma (CGB) comprises only 0.4-3.4% of all intracranial glioblastoma. The impact of surgical resection on survival and the efficacy of adjuvant therapies are uncertain as CGB is underrepresented in most studies. To elucidate prognostic factors we performed a single-institutional review of the largest series to date of CGB. The(More)
INTRODUCTION Although well recognized in breast oncology literature, histologic subtypes have not been previously described in inflammatory breast cancer (IBC). The purpose of this study was to describe lobular subtype in IBC and assess the impact of histology on patient outcomes. METHODS We performed a retrospective analysis of 659 IBC patients at MD(More)
Major breast cancer predisposition genes, only account for approximately 30% of high-risk breast cancer families and only explain 15% of breast cancer familial relative risk. The HGF growth factor receptor MET is potentially functionally altered due to an uncommon germline single nucleotide polymorphism (SNP), MET-T1010I, in many cancer lineages including(More)
Advances in treatment of sarcoma patients has prolonged survival but has led to increased disease- or treatment-related complications resulting in greater number of admissions to the intensive care unit (ICU). Survival and long-term outcome information about such critically ill patients with sarcoma is unknown. The primary objective of the study was to(More)
BACKGROUND Cancer in adolescents and young adults (AYAs) (15-39 years) is increasingly recognized as a distinct clinical and biological entity. Cancer of unknown primary (CUP), a disease traditionally presenting in older adults with a median age of 65 years, poses several challenges when diagnosed in AYA patients. This study describes clinicopathological(More)
PURPOSE To study the impact of adjuvant trastuzumab among patients achieving a pathologic complete response (pCR) after trastuzumab-based neoadjuvant systemic therapy (NST). PATIENTS AND METHODS Patients with primary HER2-positive breast cancer treated with trastuzumab-based NST were categorised according to adjuvant trastuzumab administration and pCR(More)
BACKGROUND The detection of synchronous metastases at primary diagnosis of breast cancer (BC) affects its initial management. A risk calculator that incorporates many factors to evaluate an individual's risk of harbouring synchronous metastases would be useful to adapt cancer management. PATIENTS AND METHODS Patients with primary diagnosis of BC were(More)
BACKGROUND Excisional biopsies are typically used to diagnose lymphoma, but data suggest that endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is equally effective. In this study, we determined whether EBUS-TBNA could accurately diagnose and subtype lymphoma. METHODS The cases of patients who had undergone EBUS-TBNA for(More)
