Background and purpose: To assess the impact of extended volume radiation therapy (RT) with anastomotic coverage on local control in high risk post-operative esophageal cancer patients. Patients and methods: This is a retrospective study of high risk (T(3), T(4), nodes positive, with or without margin involvement) post-operative esophageal cancer patients treated at London Regional Cancer Centre from 1989 to 1999. After esophagectomy, all patients received adjuvant combined modality therapy consisting of four cycles of fluorouracil-based chemotherapy, and loco-regional RT with or without coverage of the anastomotic site. RT dose ranged from 45 to 60 Gy at 1.8-2.0 Gy/fraction with treatment …

Breast irradiation is one of the most challenging problems in radiotherapy due to the complex shape of the target volume, proximity of radiation sensitive normal structures and breathing motion. It was the aim of the present study to use electronic portal imaging (EPI) during treatment to determine intra- and inter-fraction motion in patients undergoing radiotherapy and to correlate the magnitude of motion with patient specific parameters. EPI cine images were acquired from the medial tangential fields of twenty radiotherapy patients on a minimum of 5 days each over the course of their treatment. The treatments were administered using 10 MV …

BACKGROUND: Sentinel lymph node (SLN) biopsy allows surgeons to identify patients with subclinical nodal involvement who may benefit from lymphadenectomy and, possibly, adjuvant therapy. Several factors have been variably, and sometimes discordantly, reported to have predictive value for SLN metastasis to best select which patients require SLN biopsy.
METHODS: We reviewed 419 patients who underwent SLN biopsy for melanoma from a prospectively collected melanoma database. To derive a probabilistic model for the occurrence of a positive SLN, a multivariate logistic model was fit by using a stepwise variable selection method. The accuracy of each model was evaluated by using receiver …

PURPOSE: To determine if stratification of limited stage small cell lung cancer (LSCLC) patients by pre-treatment pulmonary function test (PFT) prognostic indicators predicts for treatment-related toxicity risks and survival following concurrent chemoradiation. MATERIALS AND METHODS: From 1989 to 1999, 215 LSCLC patients received six cycles of alternating cyclophosphamide/doxorubicin/vincristine and etoposide/cisplatin (EP). Thoracic radiation (RT) was initiated only with EP and at cycle 2 or 3. RT dose was: 40 Gy/15 fractions/3 weeks or 50 Gy/25 fractions/5 weeks. RT fields encompassed gross and suspected microscopic disease with a 2 cm margin. Pre-treatment PFT values analyzed included forced expiratory volume in 1s …
