INTRODUCTION: The evaluation of lymph nodes and the role of groin dissection for groin sarcomas has been controversial where there have not been previous studies or guidelines published. In this study, we aim to first formulate a clinical approach in the evaluation of regional lymph nodal metastases. Second, we aim to also evaluate the role of regional lymphadenectomy in the setting of pathologically involved regional lymph nodes for groin sarcomas. MATERIALS AND METHODS: In total, 43 consecutive patients with groin sarcomas underwent treatment at the National Cancer Centre Singapore between 2002 and 2015...

OBJECTIVE: Cervical cancer metastatic to the para-aortic lymph nodes (PALNs) carries a poor prognosis. Despite extended-field radiation therapy (EFRT), only 30% to 50% of patients will survive 3 years. We sought to examine the treatment regimens used, associated toxicities, and treatment outcomes in patients with cervical cancer metastatic to PALN. METHODS: A retrospective review was performed of all patients with cervical cancer treated at a single institution between January 1, 2007 and November 1, 2014...

OBJECTIVE: Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. Cyclooxygenase-2 (COX-2) overexpression is associated with increased tumor invasiveness and proliferation in CRC, and COX-2 inhibition has demonstrated chemopreventive activity. This study investigated the addition of celecoxib, a selective COX-2 inhibitor, to the irinotecan, 5-fluorouracil, and leucovorin (IFL) regimen for patients with previously untreated metastatic CRC. PATIENTS AND METHODS: Forty-seven patients enrolled in this single-arm phase II study received celecoxib at 400 mg orally twice daily in combination with weekly irinotecan (125 mg/m), 5-fluorouracil (500 mg/m), and leucovorin (20 mg/m) for 4 weeks every 6 weeks...

BACKGROUND: Brain metastases (BM) occur in ∼5% of breast cancer patients. BRCA1-associated cancers are often basal-like and basal-like cancers are known to have a predilection for central nervous system metastases. We performed a matched-pair analysis of breast cancer patients with and without BRCA mutations and compared the frequency of BM in both groups. MATERIALS AND METHODS: From a database of 1935 patients treated for localized breast cancer at our institution from 2009 to 2014 we identified 20 patients with BRCA1 or BRCA2 mutations and manually matched 40 patients without BRCA mutations accounting for age, stage, estrogen receptor expression, and human epidermal growth factor receptor 2 (HER2) expression...

OBJECTIVES: Patients with large, high-grade extremity soft tissue sarcoma (STS) are at high risk for both local and distant recurrence. RTOG 95-14, using a regimen of neoadjuvant interdigitated chemoradiotherapy with mesna, doxorubicin, ifosfamide, and dacarbazine followed by surgery and 3 cycles of adjuvant mesna, doxorubicin, ifosfamide, and dacarbazine, demonstrated high rates of disease control at the cost of significant toxicity (83% grade 4, 5% grade 5). As such, this regimen has not been widely adopted...

BACKGROUND: Health-related quality of life (HRQoL), cognitive function, and psychological status represent an important focus during the treatment of glioblastoma patients. Nevertheless, few randomized, prospective clinical trials have analyzed these factors, and very little is known in the real-clinical world. We evaluated these characteristics in glioblastoma patients treated with standard first-line therapy outside clinical trials. PATIENTS AND METHODS: In total, 111 newly, histologically diagnosed glioblastoma patients treated at our oncology center with radiotherapy and temozolomide were prospectively enrolled...

OBJECTIVE: Patients with mucosal squamous cell carcinoma (SCC) of the head and neck almost always have a primary site in the base of tongue or tonsillar fossa. Lingual tonsillectomy has recently been advocated as part of the diagnostic evaluation as opposed to directed biopsies of the base of tongue and thought to possibly result in an increased likelihood or cure. The purpose of this project is to determine whether this is probable. MATERIALS AND METHODS: We reviewed the medical records of patients treated with primary radiotherapy (RT) between January 1983 and March 2013...

INTRODUCTION: Nivolumab improves overall survival and health-related quality of life compared with everolimus in metastatic renal cell carcinoma (mRCC). This study assesses the cost-utility of nivolumab from the Canadian health care payer perspective. MATERIALS AND METHODS: To evaluate the cost-utility of nivolumab, a Markov cohort model that incorporated data from the phase 3 CheckMate-025 trial and other sources was developed. The incremental cost per quality-adjusted life month (QALM) gained for nivolumab was calculated...

OBJECTIVES: The role of radiation therapy (RT) in resected pancreatic cancer (PC) remains incompletely defined. We sought to determine clinical variables which predict for local-regional recurrence (LRR) to help select patients for adjuvant RT. MATERIALS AND METHODS: We identified 73 patients with PC who underwent resection and adjuvant gemcitabine-based chemotherapy alone. We performed detailed radiologic analysis of first patterns of failure. LRR was defined as recurrence of PC within standard postoperative radiation volumes...

PURPOSE: Placement of fiducial markers for prostate radiotherapy (RT) is associated with a 2% to 3% risk of bacterial urinary tract infection (UTI) that may progress to sepsis necessitating hospitalization. These bacterial UTIs are primarily due to flouroquinolone (FQ) resistant Escherichia coli (E. coli). The incidence of this complication has increased in recent years. The purpose of this study is to determine whether rectal culture and sensitivity (C&S) to identify FQ resistant E...

PURPOSE/OBJECTIVE(S): Stage IIIC endometrial carcinoma (EC) represents pathologically heterogenous patients with single/multiple pelvic (stage IIIC1) or paraaortic (stage IIIC2) lymph nodes (LNs). There is an increasing trend to offer adjuvant chemotherapy (CT) +/- radiation (RT) uniformly to these patients, regardless of substage. We investigate the prognostic significance of positive LN (pLN) number, ratio (%pLN), location (IIC1 vs. IIC2), and adjuvant treatment on patterns of failure and survival in a large collaborative multi-institutional series...
