Preoperative versus postoperative radiation therapy for soft-tissue sarcomas.

In this article, we report results from a retrospective consecutive series of 117 patients with soft-tissue sarcomas treated with adjuvant radiation and surgical resection at 2 associated institutions. Fifty-nine patients received preoperative radiation; 58 patients received postoperative radiation. Mean clinical follow-ups were 6.

Perspective from the Department of Defense Breast Cancer Research Program.

The Department of Defense (DOD), Breast Cancer Research Program (BCRP) was established in 1993. Since its inception, Congress has appropriated more than 878 million dollars for the BCRP, a unique public-private partnership between the DOD, consumer advocacy, and scientific communities which has funded approximately 1,800 breast cancer research grants. Through this partnership, the BCRP designed a model program for consumer involvement in scientific peer review.

Quantitative impact of including consumers in the scientific review of breast cancer research proposals.

Objective: To evaluate the impact of having breast cancer survivors with advocacy experience (consumers) participate as voting members of scientific review panels for proposals on breast cancer research. As major stakeholders, patients and other consumer advocates sought inclusion in all decision-making processes affecting funding of disease-targeted research.

Method: Cross-sectional analysis of assigned proposal scores ranging from 5.

Benefits and drawbacks of including consumer reviewers in the scientific merit review of breast cancer research.

Background: This study assessed participant opinions about inclusion of breast cancer survivors as lay representatives in a scientific and technical merit review of proposals for the 1995 Department of Defense Breast Cancer Research Program (DOD BCRP).

Methods: The evaluation employed a prepanel and postpanel survey design, which was intended to elicit feedback about attitudes, perceptions, and beliefs toward collaborative consumer and scientist participation in scientific merit review. Qualitative methods were used to describe the consumers' and scientists' responses, to explore the significance of this interaction, and to gain an understanding of the benefits and disadvantages of bringing these participants together.

Improved survival of children with isolated CNS relapse of acute lymphoblastic leukemia: a pediatric oncology group study .

Purpose: Isolated meningeal relapse in children with acute lymphoblastic leukemia (ALL) usually has been followed by bone marrow relapse and limited survival. The purpose of this study was to prevent marrow relapse by administering intensive therapy before delayed craniospinal radiation.

Patients And Methods: Eighty-three patients with ALL in first bone marrow remission with an isolated CNS relapse were treated with systemic chemotherapy known to enter into the CSF and intrathecal chemotherapy for 6 months.

Enlargement of mediastinal masses on simulation films: a radiotherapeutic problem in the management of patients with Hodgkin's disease.

The size of the mediastinal mass on standard posterior-anterior chest radiograph in stage I and stage II Hodgkin's disease has both prognostic and therapeutic importance. But the actual treatment is based on the anterior-posterior supine simulation film. Problems arise when the prognosis (whether all the disease can be effectively contained in an irradiation port) and toxicity (more lung and heart irradiated or chemotherapy required) are changed when the mass is markedly enlarged on the radiation simulation films.

Failure of preenucleation radiation to decrease uveal melanoma mortality.

We analyzed uveal melanoma metastases in a group of 41 patients who received 20 Gy of preenucleation radiation in a Northern California Oncology Group preliminary phase I/II study, and compared their survival rates with a retrospective control group of 31 patients with characteristics matching the entrance criteria but treated with enucleation alone. Using the Cox proportional hazards model, we found that increased tumor diameter, mixed or epithelioid cell type, and radiation adversely affected survival. In vivo studies of cell cycling indicated that 20 Gy of preenucleation radiation appeared to diminish the reproductive integrity of the tumor cells.

Comparison of helium-ion radiation therapy and split-course megavoltage irradiation for unresectable adenocarcinoma of the pancreas. Final report of a Northern California Oncology Group randomized prospective clinical trial.

Forty-nine patients with locally advanced carcinoma of the pancreas were treated in a randomized, prospective study comparing definitive helium ion radiation therapy with conventional split-course megavoltage photon irradiation. Patients in each treatment arm underwent exploratory staging laparotomy followed by concurrent radiation therapy and 5-fluorouracil chemotherapy. Patients treated with photons received 6,000 cGy over a period of 10 weeks; patients treated with helium irradiation received a 6,000-7,000-cGy-equivalent dose over a period of 8-9 weeks.
