Abstract

OBJECTIVE: To evaluate the efficacy of radiofrequency ablation(RFA) combined with endoscopic resection(ER) for eradicating widespread early non-flat type esophageal squamous cell carcinoma (ESCC) and precancerous lesions.

METHODS: Retrospective analysis was performed on the clinical data of 4 patients with early non-flat type ESCC and precancerous lesions in January 2010 at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences. Proportion of patients with histological complete response (CR) 3 months, 12 months to 5 years after operation and adverse events were observed.

RESULTS: These 4 patients were all male, aged from 47 to 71 (mean age 62) years, including 2 of ESCC, 1 of HGIN, 1 of MGIN confirmed by pathology. USL length was 6-12 (mean 8.5) cm. Treatment area (TA) length was 8-14 (mean 10.5) cm. Three cases were 0-II a (mean length 2 cm), and 1 case 0-II c (mean length 4 cm). Lesions of 2 cases were complete cycle, and other 2 cases occupied 3/4 circumference. Four patients completed their operations successfully. Total operation time was 42-105 (mean 66.8) min, RFA time was 3-12 (mean 8.25) min, and ER time was 6-20 (10.25) min, without bleeding and perforation. The mean hospital stay was 3 days. Pathology examination showed that 2 cases were ESCC G2 (lesion length 12, 8 cm; non-flat type lesion length 3, 4 cm), 1 was HGIN (lesion length 12 cm; non-flat type lesion length 1 cm) and 1 was MGIN (lesion length 6 cm; non-flat type lesion length 2 cm). Three cases were CR 3 months, 1 to 5 years after operation. One case had HGIN at 3-month and MGIN at 1-year and 3-year during follow up, and was CR after treatment with HALO. Postoperative esophageal stenosis occurred in 4 cases. Among them, 2 cases were mild without treatment, and 2 were severe, who were relieved by endoscopic water sac dilation for 5-8 (mean 6.5) times.

CONCLUSION: RFA combined with ER is effective and safe in the treatment of patients with early non-flat esophageal squamous cell carcinoma and precancerous lesions.
