Chemotherapy for pancreatic cancer
Abstract
To date, no satisfactory treatment has been developed for treatment of patients with advanced pancreatic carcinoma. The median survival of these patients is only three to six months. Of more than 30 agents evaluated over the past three decades, only 5-FU results in a response rate with 95% confidence intervals greater than 20%. Most responses are partial, of short duration, and of questionable clinical benefit. To date, efforts to improve response rates by biochemical modulation of 5-FU have been unsuccessful but additional studies are warranted and are ongoing. Although improved response rates have been reported with some drug combinations, such as streptozotocin, mitomycin and 5-FU (SMF), median survival for combination therapy is no better than that attained with single-agent therapy. Current therapeutic options for patients with advanced disease include 5-FU, supportive care, or investigational treatment in a clinical trial. In three out of four studies, patients with locally advanced pancreatic carcinoma who received combined modality therapy (radiation in combination with 5-FU) survived significantly longer than those treated with either radiation or chemotherapy alone. The brief survival advantage, however, must be considered in the context of the additional toxicity and treatment time required for the combined modality treatment. Radiotherapy in combination with 5-FU should be considered standard adjuvant therapy for patients with completely resected disease. The…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
