Thoracoscopic lobectomy as salvage surgery for local recurrence of non-small cell lung cancer after carbon ion radiotherapy in an initially operable patient

Carbon ion radiotherapy (CIRT) for patients with early-stage non-small cell lung cancer (NSCLC) has recently provided favorable local control with very few toxic reactions. Because CIRT for NSCLC has been mostly performed for elderly or inoperable patients, salvage surgery for NSCLC after CIRT has rarely been reported. We describe a case of complete thoracoscopic right upper lobectomy with mediastinal lymphadenectomy performed as salvage surgery for local recurrence of stage IA NSCLC after CIRT in an initially operable patient who had refused surgery 27 months previously. Pleural adhesions caused by CIRT were localized to the pulmonary apex and the central pulmonary structures were intact at the time of the salvage surgery, which allowed us to successfully perform thoracoscopic lobectomy without any complications. Thus, salvage surgery for NSCLC after CIRT may be feasible in an initially operable patient, as CIRT appears to be unlikely to cause any difficulties in the salvage surgery.
