We could detect the lateral SNs, not only in T1 and T2 disease, but also in T3 disease. Although this is only a preliminary study, the detection of lateral SNs in lower rectal cancer by means of the ICG fluorescence imaging system is considered to be a promising technique that may be used for determining the indications for performing LPLD.

Objective: Esophageal squamous cell carcinoma (ESCC) is refractory to current therapeutic regimens and more effective therapies are imperative. To this end, we conducted a multicenter phase I/II trial of docetaxel, cisplatin, and fluorouracil (DCF) combination chemotherapy for ESCC. Methods: The study subjects were 46 patients with advanced or recurrent ESCC. Treatment included docetaxel at 60, 70, and 75 mg/m², cisplatin at 70 mg/m² on day 1, and daily fluorouracil at 700 mg/m² on days 1 through 5. The recommended dose of docetaxel was determined in phase I, while the response rate (RR) and progression-free survival rates were analyzed in phase II. Results: The recommended dose was determined to be 70 mg/m² in phase I. In phase II, the RR was 72.5%. Interim analysis showed median and 1-year progression-free survival of 14 months and 55.6%, respectively. Grade 3/4 toxicities of leukopenia and neutropenia occurred in 72.5 and 90% of patients, respectively. No treatment-related death was recorded. Surgical resection was subsequently performed in 20 patients after chemotherapy, and curative resection was achieved in 19. Conclusion: DCF was tolerable and effective for advanced and recurrent ESCC. Such findings might encourage a change in the treatment strategy for ESCC.

Our newly developed laparoscopic ICG fluorescence imaging system is promising in the detection of SNs in laparoscopic gastric cancer surgery. The preliminary results suggest an easier and shorter learning curve of dye-guided SN biopsy in laparoscopic gastric surgery.
