Treatment perspectives in locally advanced unresectable pancreatic cancer.

Locally advanced unresectable pancreatic cancer is sometimes encountered without manifest distant metastases. Twenty patients with histologically proven unresectable pancreatic cancer without distant metastases were treated with radiotherapy and 5-fluorouracil (5-FU). Radiotherapy consisted of 50 Gy external upper abdomen radiation in two courses, concomitant with intravenous 5-FU 375 mg/m2 given as a bolus injection 4-6h before radiation on the first 4 days of each treatment course. The treatment protocol was completed in 18 patients without complications. The median survival time was 10 months which compares favourably with a 3-5 months median survival time when treatment is withheld. Nine patients (45 per cent) were alive at 1 year, two patients at 2, 3 and 4 years. A second-look operation was performed in four patients 6, 11, 12 and 22 months after completion of radiotherapy. In two patients the tumour could be resected. It appears that treatment with radiotherapy and 5-FU may benefit patients with locally advanced unresectable pancreatic cancer.
