Disease recurrence after surgical resection reduces the patient's life expectancy sharply. The prognosis after postoperative recurrence is considered to largely depend on both the mode of first recurrence(distant, locoregional or combined) and the treatment modality:(1) The majority of cases of postoperative recurrence involve distant metastasis with or without locoregional recurrence. Platinum-based systemic chemotherapy is practically accepted as the treatment for these diseases on the basis of evidence for original stage Ⅳ disease. The advent of both pemetrexed and molecular-targeted drugs has improved the survival of nonsquamous NSCLC and changed the chemotherapeutic algorithm for NSCLC;(2) Among patients with distant metastatic recurrence without locoregional recurrence at the primary tumor site, the metastasis is often limited in both organ and number. Such metastases are referred to as oligometastases. Local therapy, such as surgical resection and radiotherapy, has been suggested to be the first-line treatment of choice foroligometastatic recurrence; and(3) While locoregional recurrence is likely to cause troublesome symptoms, it is a potentially limited disease. Therefore, providing local control is important, and radiation is usually beneficial for treating local recurrence. In order to obtain better control of the disease and provide treatment with curative intent in patients with limited disease, the administration of concurrent platinum-based chemoradiotherapy is recommended according to the results of originally nonresectable stage ⅢA and ⅢB disease.展开更多

The primary endpoint of this study was compliance, while the secondary endpoints were the adverse events(AE) and recurrencefree survival(RFS).RESULTS: Sixty-one patients were treated in this study arm. The patients were 43 males and 18 females, with a median age of 64.6 years. Fifty-one patients(83.6%)completed all three cycles of therapy. The presence of Grade 3 and 4 neutropenia was noted in 25% and 66%of the patients, respectively. The non-hematological AE were less frequently reported, and no treatmentrelated death was registered. The two-year RFS and OS rates of the 61 patients were 69.8% and 88.3%,respectively.CONCLUSION: A tri-weekly schedule of CBDCA and DTX as adjuvant chemotherapy showed a favorable feasibility.展开更多
