IntroductionThoracoscopic or video-assisted thoracic esophagectomies have been performed for the last 10 years. Nevertheless, some reports have showed a risk of dissemination with endoscopic or video-assisted surgery for malignant disease. This institute experienced three cases of port site recurrence after a thoracoscopic esophagectomy for advanced esophageal cancer. Following those cases, induction chemo-radiation therapy was performed for patient with advanced esophageal cancer before thoracoscopic or video-assisted esophagectomy. Since introducing induction chemo-radiation therapy, no patients have experienced port site recurrence after a thoracoscopic or video-assisted esophagectomy for advanced esophageal cancer. In this study, the two patients groups are compared before and after the introduction of induction chemo-radiation therapy.Patients And MethodsBetween November 1995 and December 2005, thoracoscopic and video-assisted esophagectomies were performed on 112 (72.7%) patients out of 154 who underwent a surgical resection for thoracic and abdominal esophageal cancer. The histologic type of cancer was squamous cell carcinoma in 109 (97.4%) patients and adenocarcinoma in 3 (2.6%). Ninety-one patients were men and 21 were women. The tumor was located in the upper thoracic esophagus in 22 (19.6%) patients, the middle thoracic esophagus in 49 (43.8%), the lower thoracic esophagus in 34 (30.4%), and the abdominal esophagus in 7 (6.2%).ResultsBefore December 1999, port site recurrence occurred in three cases of those of 29 patients with clinical T2-T4 esophageal cancer from 3 to 6 months after surgery, and pleural dissemination was observed in two of those patients. Since January 2000, induction chemo-radiation therapy (low-dose fluorouracil and platinum + 40 Gy radiation) has been performed to 31 patients with clinical T2-T4 disease, and port site recurrence has not occurred in any patients who received trimodality therapy.ConclusionsWe think that the trend toward less port site recurrences with induction therapy should be examined in future studies of video-assisted thoracic surgery esophagectomy to confirm our findings.
