Objectives:
The aim of this study was to report a single referral centre experience in robotic extended thymectomy for clinical early-stage thymomas, evaluating its safety, feasibility and efficacy, with special regard to oncological outcomes.
Methods:
Between April 2002 and February 2011, we retrospectively selected all those patients who underwent robotic thymectomy for clinical early-stage thymomas. Operative time, morbidity, mortality, duration of hospitalization and overall and disease-free survival were analysed.
Results:
There were 14 patients (8 males, 6 females) with a mean age of 65.2 years (range 23-81). One patient suffered from myasthenia gravis. The WHO classifications were: A in two cases, AB in four cases, B1 in three cases, B2 in two cases and B3 in three cases. The Masaoka stages were: I in seven cases, IIA in four cases, IIB in two cases and III in one case. The mean operative time was 139 min. No intra-operative complication or death occurred. Conversion to open surgery was required in two cases. Minor complications occurred in two patients (14.2%) due to pleural effusion. The mean hospitalization was 4.0 days. Five patients underwent adjuvant radiotherapy. All patients were alive with no disease recurrence, with a median follow-up of 14.5 months (range 1-98).
Conclusions:
Robotic thymectomy is a safe and feasible technique, with a short operative time and low morbidity. Even on a small series with short follow-up, robotic extended thymectomy for thymoma appeared to be an effective treatment for early-stage thymomas.
