    Abstract:
    BACKGROUND: Concurrent 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 METHODS: Between 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. RESULTS: Eighteen 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%. CONCLUSION: We suggest that for locally advanced esophageal cancer CCRT with the aforementioned daily low-dose regimen, is a treatment with good patient compliance.
