Background: Adjuvant cisplatin-based chemotherapy benefits selected patients with stages II and III non-small cell lung cancer (NSCLC). However, carboplatin being tolerated better than cisplatin, carboplatin-based adjuvant therapy may have better chemotherapy compliance. This study aimed to investigate the feasibility and toxicity of adjuvant carboplatin and docetaxel in patients with completely resected locally advanced NSCLC.
Methods: Eighty patients with completely resected locally advanced NSCLC were enrolled in this trial. Adjuvant chemotherapy was initiated between 1 and 4 weeks after surgery, and consisted of four cycles of carboplatin (AUC=5), and docetaxel (Taxotere, 75mg/m(2)) every 3 weeks, after which patients received prophylactic G-CSF supportive therapy.
Results: Patient demographics were: Median age 55 years (range 34-73): gender ratio was 56.3% male/43.7% female: 72.5% of the patients were at stage IIIA and 27.5% were at stage IIIB. The two most common histologies were adenocarcinoma (62.5%) and squamous cell carcinoma (17.5%). Sixty-six patients (82.5%) received four cycles of therapy over a 12-week period. Fourteen patients (17.5%) did not complete therapy due to: patient refusal (n=12), severe adverse events (n=1) and bone metastases during chemotherapy (n=1). No treatment related deaths were observed and the primary adverse events were hematologic toxicity, alopecia, fatigue and gastointestinal reaction (nausea, vomiting and diarrhea).
Conclusion: Combination therapy with carboplatin and docetaxel with the use of G-CSF supportive therapy has an acceptable toxicity profile such that the majority of patients completed four cycles of therapy in 12 weeks.
