First author research productivity of United States radiation oncology residents: 2002-2007.

Purpose: Participation in investigative research is a required element of radiation oncology residency in the United States. Our purpose was to quantify the first author research productivity of recent U.S.

Relative risk of stroke in head and neck carcinoma patients treated with external cervical irradiation.

Objective: To determine the rate of cerebrovascular events (stroke) in patients irradiated to high doses for squamous cell carcinoma of the head and neck.

Study Design: Retrospective chart review of 413 patients treated from 1987 to 2000 with squamous cell carcinoma of the head and neck was performed to determine the risk of stroke compared with the expected rate.

Methods: Surgical, radiotherapeutic, radiological, and clinical or office records of 413 patients were analyzed, and data were collected regarding clinical risk factors for stroke, irradiation parameters, and follow-up on whether or not a stroke event occurred.
