Optimal Frequency of Psychosocial Distress Screening in Radiation Oncology.

PURPOSE: To accurately hypothesize the optimal frequency of psychosocial distress screening in patients undergoing radiation therapy using exploratory modeling of prospective data. MATERIALS AND METHODS: Between October 2010 and May 2011, 71 RT patients underwent daily screening with the Distress Thermometer. Prevalences of Distress Thermometer scores ≥ 4 were recorded. Optimal screening frequency was evaluated by planned post hoc comparison of prevalence rates and required screening events estimated by numerical modeling, consisting of data point omission to mimic weekly, every-other-week, monthly, and one-time screening intervals. Dependence on clinical variables and chronologic trends were assessed as secondary end points. RESULTS: A total of 2,028 daily screening events identified that 37% of patients reported distress at least once during the course of treatment. Weekly, every-other-week, monthly, and one-time screening models estimated distress prevalences of 32%, 31%, 23%, and 17%, respectively, but required only 21%, 12%, 7%, and 4% of the assessments required for daily screening. No clinical parameter significantly predicted distress in univariable analysis, but "alone" living situation trended toward significance (P = .06). Physician-reported grade 3 toxicity predicted distress with 98% specificity, but only 19% sensitivity. CONCLUSION: Thirty-seven percent of radiation oncology patients reported distress at least once during treatment. Screening at every-other-week intervals optimized efficiency and frequency, identifying nearly 90% of distressed patients with 12% of the screening events compared with daily screening.

Use of radiation therapy for patients with soft-tissue and bone sarcomas.

Radiation therapy is recommended as an adjuvant to resection for intermediate- and high-grade soft-tissue sarcomas; its role in bone sarcomas is largely limited to select patients with Ewing sarcoma. Despite the integral role of radiation therapy in soft-tissue sarcoma management, its optimal timing--preoperative versus postoperative--is uncertain, with each timing scenario having advantages and disadvantages. Preparation for radiation therapy involves a detailed planning session to optimize and standardize patient positioning and determine the target volume. Side effects of radiation therapy may include skin changes, delayed wound healing and other wound complications, fatigue, reduced range of motion of the affected limb, pain, and bone fractures.

Metastatic adrenocortical oncocytoma: a case report.

With only 51 cases reported in the literature to date, adrenocortical oncocytoma is an exceedingly rare pathological variant of adrenal neoplasms. The first case of metastatic adrenocortical oncocytoma is reported along with an update of the literature. A role for radiotherapy in the palliative setting is demonstrated.
