Purpose: A multi-institutional phase 2 trial assessed long-term outcomes of dose-painted intensity modulated radiation therapy (IMRT) with 5-fluorouracil (5FU) and mitomycin-C (MMC) for anal canal cancer.
Methods And Materials: T2-4N0-3M0 anal cancers received 5FU (1000 mg/m/d, 96-hour infusion) and MMC (10 mg/m bolus) on days 1 and 29 of dose-painted IMRT prescribed as follows: T2N0 = 42 Gy elective nodal and 50.4 Gy anal tumor planning target volumes, 28 fractions; T3-4N0-3 = 45Gy elective nodal, 50.
Purpose: NRG Oncology RTOG 0529 assessed the feasibility of dose-painted intensity modulated radiation therapy (DP-IMRT) to reduce the acute morbidity of chemoradiation with 5-fluorouracil (5FU) and mitomycin-C (MMC) for T2-4N0-3M0 anal cancer. This secondary analysis was performed to identify patient and treatment factors associated with acute and late gastrointestinal (GI) adverse events (AEs).
Methods And Materials: NRG Oncology RTOG 0529 treatment plans were reviewed to extract dose-volume data for tightly contoured small bowel, loosely contoured anterior pelvic contents (APC), and uninvolved colon outside the target volume (UC).
Purpose: To report the feasibility, toxicity, cosmesis, and efficacy of using intensity-modulated radiation therapy (IMRT) with respiratory gating to deliver accelerated partial breast irradiation (APBI) in selected Stage I/II breast cancer after breast-conserving surgery.
Methods And Materials: Eligible patients with node-negative Stage I/II breast cancer were prospectively enrolled in an institutional review board approved protocol to receive APBI using IMRT after breast-conserving surgery. The target volume was treated at 3.
Background: Our aim was to determine whether percutaneous endoscopic gastrostomy (PEG) dependence was significantly different between 2 prospective trials with different radiation fractionation schemes.
Methods: Stage III or IV locally advanced head and neck squamous cell carcinomas arising from the oral cavity, hypopharynx, oropharynx, nasopharynx, paranasal sinuses, or larynx were treated using hyperfractionation (A-3 protocol) or accelerated fractionation (A-4 protocol) with chemotherapy. Amifostine was administered 15 to 30 minutes preradiation, at a dose of 500 mg/day in both protocols.
Objective: To evaluate the efficacy of using image-guided robotic stereotactic radioablation as an alternative treatment modality for patients with surgically resectable, but medically inoperable, T1 N0 M0, stage IA non-small cell lung cancer.
Methods: Between January 2004 and May 2006, 19 patients, 11 women and 8 men ranging in age from 52 to 88 years, with stage IA non-small cell lung cancer were treated. Tumor volume ranged from 1.
Background: Severe swallowing dysfunction is the dominant long-term complication observed in patients treated for head and neck squamous cell carcinoma (HNSCC) with treatment protocols using intensive concurrent chemotherapy with radiation therapy (chemo/XRT). We identified a subset of these patients, who were seen with complete obstruction of the hypopharynx distal to the site of the primary cancer, and in whom we postulate that the obstruction was caused by separable mucosal adhesions rather than obliteration by a mature fibrous stricture.
Methods: Seven patients were referred to the senior author with a diagnosis of complete hypopharyngeal obstruction between 1992 and 2001.
The objective of this study was to determine the toxicity and efficacy of the current phase II chemoradiation protocol. Stage III or IV locally advanced head and neck squamous cell carcinomas arising from the oral cavity, hypopharynx, oropharynx, nasopharynx, paranasal sinuses, or larynx were treated using hyperfractionated radiation (74.4 Gy at twice-daily fractions of 1.

Materials And Methods: Functional Assessment of Cancer Therapy (FACT) and the Functional Assessment of Cancer Therapy-Head and Neck (FACT H-N) questionnaires were administered to protocol patients at baseline study entry, during and at the completion of therapy, and during subsequent follow-up.
Results: Twenty-four patients completed baseline QOL questionnaires.
Purpose: To determine the toxicity and efficacy of concurrent 5-fluorouracil (5-FU), cisplatin, and paclitaxel (Taxol) and hyperfractionated radiotherapy in locally advanced squamous cell carcinoma of the head and neck.
Methods And Materials: Twenty-seven patients were entered into this Phase II trial. Eligible patients had Stage III or IV head-and-neck squamous cell carcinoma arising from the oral cavity, hypopharynx, oropharynx, nasopharynx, or larynx.
