Case 1:A 62-year-old man, who had undergone right upper lobectomy for lung squamous cell carcinoma (pT2pN2M0, stage IIA) 4 months earlier, was diagnosed as mediastinal lymph node recurrence by chest CT. Case 2: A 63-year-old woman, who had undergone right middle-lower lobectomy for lung squamous cell carcinoma (pT2pN1M0, stage IIB) 16 months earlier, was diagnosed as hilar lymph node recurrence by chest CT. Both patients underwent radiochemotherapy with 2 cycles of cisplatin (CDDP) 80 mg/m2 on day 1 and vinorelbine (VNR) 15 mg/m2 on day 1 and another day (day 8-16), and concurrent radiation (60 Gy/30 fr) for mediastinum. After this treatment, a partial response (PR) in case 1 and a complete response (CR) in case 2 were achieved, and neither patient showed any relapse after 3 years of the treatment. Adverse reactions were grade 3 neutropenia in both patients and transient hemiparalysis in case 2. Concurrent radiochemotherapy with cisplatin and vinorelbine is considered effective without serious side effects for postoperative recurrence in localized mediastinal lymph nodes of non-small-cell lung cancer.
