Protracted venous infusion 5-fluorouracil with concomitant radiotherapy compared with bolus 5-fluorouracil for unresectable pancreatic cancer.

Radiation therapy (RT) with concurrent 5-fluorouracil (5-FU) administered by protracted venous infusion (PVI) replaced our prior institutional protocol of RT with bolus administration of 5-FU as standard therapy for unresectable pancreatic cancer in 1994. In this article, we compare the treatment intensity, toxicity, and outcome for patients with unresectable pancreatic cancer treated on these sequential protocols. Fifty-four patients, 27 on each protocol, with biopsy-confirmed pancreatic cancer received chemoradiotherapy.

Preoperative chemoradiation for marginally resectable adenocarcinoma of the pancreas.

Only 10% to 20% of patients with pancreatic cancer are considered candidates for curative resection at the time of diagnosis. We postulated that preoperative chemoradiation therapy might promote tumor regression, eradicate nodal metastases, and allow for definitive surgical resection in marginally resectable patients. The objective of this study was to evaluate the effect of a preoperative chemoradiation therapy regimen on tumor response, resectability, and local control among patients with marginally resectable adenocarcinoma of the pancreas and to report potential treatment-related toxicity.

Adjuvant chemoradiotherapy for "unfavorable" carcinoma of the ampulla of Vater: preliminary report.

Hypotheses: Adjuvant chemoradiotherapy decreases the risk of local recurrence in patients with adenocarcinoma of the ampulla of Vater and high-risk features. Adjuvant chemoradiotherapy for this population can be administered safely and without much morbidity.

Design: Controlled, prospective, single-arm study.

Adjuvant radiotherapy and concomitant 5-fluorouracil by protracted venous infusion for resected pancreatic cancer.

Purpose: To assess the toxicity and clinical benefit from adjuvant chemoradiotherapy consisting of protracted venous infusion 5-fluorouracil (5-FU) and concomitant radiotherapy in patients with resected pancreatic cancer.

Methods And Materials: Between 1994 and 1999, 52 patients who underwent pancreaticoduodenectomy received adjuvant chemoradiotherapy. The tumor bed and regional nodes received a dose of 45 Gy in fractions of 1.

Chemo-radiotherapy for localized pancreatic cancer: increased dose intensity and reduced acute toxicity with concomitant radiotherapy and protracted venous infusion 5-fluorouracil.

Purpose: Although concomitant radiation therapy (RT) and bolus 5-Fluorouracil (5-FU) have been shown to improve survival in locally confined pancreatic cancer, most patients will eventually succumb to their disease. Since 1994, we have attempted to improve efficacy by administering 5-FU as a protracted venous infusion (PVI). This study compares treatment intensity and acute toxicity of consecutive protocols of concurrent RT and 5-FU by bolus injection or PVI.

Pseudomyxoma peritonei.

Pseudomyxoma peritonei results from implantation of malignant tumors or irritation from ruptured benign cysts. This disease is traditionally characterized by accumulation of mucinous ascites, relatively long survival period and absence of extraperitoneal metastases. Disease progression is difficult to predict because of the spectrum of underlying pathologic entities.

A reappraisal of the Kock continent ileostomy in patients with Crohn's disease.

The diagnosis of Crohn's disease has been considered a contraindication to the construction of a Kock continent ileostomy. From 1975 to 1984, 95 Kock continent ileostomies were performed at the Stanford University Medical Center. The clinical course of seven patients with regional enteritis who were disease-free for five years was reviewed.
