Improved compliance with adjuvant vinorelbine and cisplatin in non-small cell lung cancer.
OBJECTIVE
Poor compliance has been a common feature in clinical trials of adjuvant chemotherapy for NSCLC with only 48% to 69% of patients completing all planned cycles. We retrospectively evaluated compliance and toxicity of platinum-based chemotherapy in the 2 years following recent reports of successful adjuvant chemotherapy trials for NSCLC.


METHODS
Patients who received adjuvant chemotherapy after complete resection of NSCLC between May 2003 and May 2005 were analyzed retrospectively. Patient demographics, ECOG status, stage, pathologic subtype and type of surgery were recorded. The number of chemotherapy cycles, delays, dose reductions and change of chemotherapy were reported.


RESULTS
Fifty patients were identified. The median age was 62 years (38% stage I, 18% stage II, 30% stage III and 14% had multiple primary tumors of variable stages). Twenty percent were ECOG PS2; Only 12% had undergone pnemonectomy. Forty-one patients (82%) started cisplatin/vinorelbine (three switched to carboplatin because of nephrotoxicity, and one switched to carboplatin/paclitaxel because of fatigue and vomiting). Three patients received other cisplatin-based combinations; six received carboplatin-based treatment (one each because of advanced age and cardiac dysfunction and 4 because of preexisting neuropathy). Eighty percent completed all treatment; 40% required a dose reduction and 58% required delays in treatment. Six events of febrile neutropenia were reported in 5 patients and 5 patients required admission for toxicity. There were no toxic deaths. Multivariate analysis showed no effect of age, gender, extent of surgery or ECOG status on compliance, need for treatment modification or toxicity.


CONCLUSIONS
Compared to historical trials, adjuvant platinum-based chemotherapy for resected NSCLC is now accepted by patients and physicians with a high degree of compliance.
