Objective: To determine whether esophagectomy provides a survival advantage in octogenarians with resectable thoracic esophageal cancer. Summary Background Data: Elderly patients with thoracic esophageal cancer do not always receive the full standard treatment; however, advanced age alone should not preclude the use of effective treatment that could meaningfully improve survival. Methods: We retrieved the 2008 to 2011 data from the National Database of Hospital-based Cancer Registries from the National Cancer Centerin Japan, divided the patients into a !75 group (75-79 years; n ¼ 2935) and a !80 group (80 years or older; n ¼ 2131), and then compared the patient backgrounds and survival curves. A multivariable Cox proportional hazards regression model was developed to compare the effects of esophagectomy and chemoradiotherapy in the 2 groups. Results: A significantly greater percentage of patients were treated with esoph-agectomy in the !75 group (34.6%) than the !80 group (18.4%). Among patients who received esophagectomy, the 3-year survival rate was 51.1% in the ! 75 group and 39.0% in the !80 group (P < 0.001). However, among patients who received chemoradiotherapy, there was no difference in survival curve between the 2 groups (P ¼ 0.17). Multivariable Cox proportional hazard analysis revealed that esoph-agectomy for clinical Stage ii-iii patients was significantly associated to better survival (adjusted HR: 0.731) (95%CI: 0.645-0.829, P < 0.001) in the !75 group but not the ! 80 group when compared with chemoradiotherapy. Conclusions: Many octogenarians do not necessarily get a survival benefit from esophagectomy. However, patients should be evaluated based on their overall health before ruling out surgery based on age alone.

The oncological advantages of robot-assisted thoracoscopic esophagectomy (RATE) over conventional thoracoscopic esophagectomy (TE) for thoracic esophageal cancer have yet to be verified. In this study, we retrospectively analyzed clinical data to compare the incidences of recurrence within the surgical field after RATE and TE as an indicator of local oncological control. Among 121 consecutive patients with thoracic esophageal or esophagogastric junction cancers for which thoracoscopic surgery was indicated, 51 were treated with RATE while 70 received TE. The number of lymph nodes dissected from the mediastinum, duration of the thoracic portion of the surgery, and morbidity due to postoperative complications did not differ between the two groups. However, the rate of overall local recurrence within the surgical field was significantly (P = 0.039) higher in the TE (9%) than the RATE (0%) group. Lymph node recurrence within the surgical field occurred in left recurrent nerve, left tracheobronchial, left main bronchus and thoracic paraaortic lymph nodes, which were all difficult to approach to dissect. The other two local failures occurred around the anastomotic site. This study indicates that using RATE enabled the incidence of recurrence within the surgical field to be reduced, though there were some limitations.
