A randomized study of radiotherapy alone versus radiotherapy plus 5-fluorouracil and platinum in patients with inoperable, locally advanced squamous cancer of the esophagus.
Squamous cell cancer of the esophagus is the most common cancer among black South African males, and 60% of patients present with localized inoperable disease. Combined chemoradiotherapy has been reported to be superior to radiotherapy alone for localized inoperable esophageal cancer in North American patients. A study was carried out to determine if this was also applicable to South African patients, who present with more advanced disease. From September 1991 through June 1995, 70 patients with locally advanced (T3N0-1M0) squamous cancer of the esophagus were prospectively randomized to receive radiotherapy alone or radiotherapy combined with cisplatin and 5-fluorouracil. There was no statistically significant survival difference between the two groups. The median survival was 144 days in the group receiving radiotherapy alone, and 170 days in the group receiving radiotherapy combined with chemotherapy (p = 0.42). The degree of weight loss before initiation of therapy had a significant effect on survival regardless of the treatment arm. Radiotherapy in combination with chemotherapy, as administered in this study for South African patients with locally advanced, inoperable squamous cancer of the esophagus, is no better than radiotherapy alone.
