ORAL04.07 - Adjuvant Chemotherapy in Patients with Resected Non-Small-Cell-Lung Cancer Treated with Carboplatin and Oral Vinorelbine - SWITCH I Study (ID 497)
10:45 - 12:15 | Author(s): L. Ostrizkova
Adjuvant cisplatinum-based chemotherapy is recommended in patients with stages IB (≥ 4 cm), IIA, IIB, and IIIA of non small-cell lung cancer (NSCLC) after radical resection. Vinorelbine with cisplatin are preferable drugs in this indication, but the side effects of this treatment were not negligible in big adjuvant trials. Carboplatin with vinorelbine given intravenously switched to orally were applied in a multicentre prospective study SWITCH I to give better comfort, higher tolerability and comparable effectivenes as standard adjuvant chemotherapy. The recruitment period started in January 12[th], 2005 and lasted till September 5[th], 2008.
Consecutive chemo-naive patients were recruited after complete resection of NSCLC stages IB, IIA, IIB and IIIA. Chemotherapy was applied from 2 to 6 weeks after complete resection. Four cycles of 21 days regimens were planned, Patients received carboplatin AUC 5 on the day 1,vinorelbine 25 mg/m intravenously on the day 1 switched to 60 mg/m orally on the day 8. Follow-up visits with physical evaluation, chest CT and laboratory tests have been realized every 3 months for 2 years and then every 6 months. Tolerability, side effects, relative dose intensity and survival were evaluated.
Seventy four patients (pts) were recruited to the SWITCH I study: 53 men and 21 women, 45 smokers, 23 ex- smokers and 6 non-smokers. Median age was 64 y (48-75 y). Tumor was squamous in 46, adenocarcinoma in 22, giant cell in 4 and NOS in 2 pts. Stage of the tumor was IB in19, IIA in 8, IIB in 22 and IIIA in 25. Mean number of applied cycles was 3.77 four planned cycles finished 82,4% patients. The most frequent hematological toxicities grade 3/4 were neutropenia (25.7 %), leukopenia (16.2 %), anemia (8.1 %) and trombocytopenia (2.7 %). Non-hematological toxicities were alopecia (12.2 %), nausea (4.1%), nefrotoxicity (1.4%) and diarrhoea (1,4%). Median of follow up was 4.73 y. Median of disease specific survival was 7.63 y (95% CI: 4.57 to NR), median of overall survival (MOS) was 5.9 y (95% CI, 3.7 to, NR) and median of disease free survival (DFS) 4.43 y . Three-year survival of 70.3% and five-year survival of 56,2% were reached.
Adjuvant chemotherapy with carboplatinum and vinorelbine given intravenously on the day 1 and orally on the day 8 in 21 day regimen appears to be a comfortable and tolerable therapy in radically resected NSCLC. It provides higher dose intensity and more of acomplished treatments compared to big adjuvant trials and LACE meta-analysis, in which these parametres varied between 50 % to 76 % only. Survival results are comparable to LACE (3-year survival 70,3% vs 64.3%), 5-year survival 56,2% vs 55.1%) and MOS 5.9 vs 5.15 y).
