BackgroundConcurrent chemoradiotherapy (CCRT) has recently become a promising treatment for esophageal cancer. However, most investigators have adopted the conventional or modified Wayne-State PF (cisplatin plus 5-fluorouracil) regimen, which is inevitably associated with moderate to severe treatment-related toxicities. In this pilot study, we incorporated a daily low-dose regimen of cisplatin and 5-fluorouracil into CCRT in order to improve the compliance of the patients.Patients And MethodsBetween July 1993 and Dec. 1997, 25 patients with locally advanced esophageal cancer (T3, or N1 disease), received CCRT which consisted of daily low-dose cisplatin (6 mg/m2/day) and continuous infusion of 5-FU (225 mg/m2/day) with radiotherapy (fraction size = 200-250 cGy/day). Except for the initial 9 patients, for whom post-CCRT esophagectomy was compulsory, all subsequent patients underwent esophagectomy only when inadequate response to CCRT was noted. The scheduled radiation dose was 50 Gy for the first 9 patients, and 60 Gy for the rest of the patients.ResultsEighteen patients (72%) completed the CCRT without interruption. Clinically, there were 8 CR and 9 PR, with a total response rate of 68% (47-87%, 95% C.I.). All patients were evaluable for toxicity. Grade 3/4 leukopenia and thrombo-cytopenia developed in 14 (56%) and 7 (28%) patients, respectively. Grade 3/4 non-hematologic toxicity was seen in 4 (16%) patients. The median survival of the whole group was 8 months (range: 2-59+). The projected 3-year overall survival was 24%.ConclusionWe suggest that for locally advanced esophageal cancer CCRT with the aforementioned daily low-dose regimen, is a treatment with good patient compliance.
