A phase I study was conducted to determine the maximum-tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of a CPT-11 plus cisplatin combination as salvage treatment in patients with advanced non-small cell lung cancer (NSCLC). Twenty-two patients with histologically confirmed NSCLC, who had failed taxotere-based front-line chemotherapy, were enrolled. The patients' median age was 61 years, 19 (86%) were male, and 17 (77%) had a performance status (World Health Organization (WHO)) 0-1. CPT-11 was administered as a 60-min i.v. infusion at a fixed dose of 100 mg/m2 on day 1 and at escalating doses on day 8, starting from 100 mg/m2 with increments of 10 mg/m2; cisplatin was administered at a fixed dose of 80 mg/m2 on day 8, 2 h after CPT-11 administration. Treatment was repeated every 3 weeks. At the dose of CPT-11 120 mg/m2, three out of four enrolled patients presented DLTs (grade 4 neutropenia, febrile neutropenia and delayed diarrhea); the addition of G-CSF at this level did not permit further dose-escalation. Grade 3/4 neutropenia was observed in 12 (18%) cycles, febrile neutropenia in four (6%), and grade 3/4 thrombocytopenia in four (6%). Grade 3/4 diarrhea was seen in six (29%) patients, and grade 2/3 nausea and vomiting in 12 (57%). Neurotoxicity grade 2 was observed in six (29%) patients and grade 3 in one (5%). Other toxicities were mild. The MTD was CPT-11 100 mg/m2 on day 1 and 110 mg/m2 on day 8 in combination with CDDP 80 mg/m2 on day 8. Among 12 patients evaluable for response, partial response was achieved in two (16.7%) patients and stable disease in five (41.7%). The combination of CPT-11 and cisplatin has substantial but manageable toxicity and marginal activity as salvage treatment of patients with NSCLC who have failed taxotere-based front-line chemotherapy: further investigation is warranted to define its precise role in the second-line setting.

BACKGROUND:Irinotecan has significant activity in small-cell lung cancer (SCLC). The authors' previous phase 1 study of alternating weekly therapy with irinotecan/cisplatin (IP), etoposide/cisplatin (EP), and granulocyte–colony-stimulating factor (G-CSF) support was well tolerated and active in patients with SCLC. A phase 2 trial was conducted to estimate the efficacy of this regimen in previously untreated patients with extensive SCLC.Irinotecan has significant activity in small-cell lung cancer (SCLC).

Irinotecan (CPT-11) and cisplatin (P) are both active agents against non-small cell lung cancer (NSCLC), and their combination has shown in vitro an additive or synergistic effect. We conducted a phase II study to determine the toxicity and efficacy of their combination as salvage treatment in patients with advanced NSCLC progressing after a docetaxel-based front line regimen. Forty-four patients with histologically confirmed NSCLC were enrolled. The patients' median age was 60.5 years; 39 patients (87%) were male; 38 (86%) had stage IV disease; and 32 (73%) had a performance status (WHO) 0-1. CPT-11 was administered as a 60 min i.v. infusion at a dose of 100 mg/m(2) on day 1 and 110 mg/m(2) on day 8; P was administered at a dose of 80 mg/m(2) on day 8 after CPT-11 administration. Treatment was repeated every 3 weeks. A total of 159 chemotherapy cycles was administered. In an intention-to-treat analysis, nine patients (22; 95% CI: 9.28-34.62%) achieved a partial response (PR), 8 (20%) had stable disease (SD), and 24 (58%) progressive disease (PD). The median duration of response was 4 months, the median time-to-progression (TTP) 8 months, and the median survival for the entire group 8 months. Grade 3-4 neutropenia was observed in 20 (46%) patients and in four cases this was febrile, requiring patient's hospitalisation. Grade 3-4 thrombocytopenia occurred in four (9%) patients. Grade 3-4 diarrhoea was seen in 12 (27%) patients and three of them required hospitalisation. Grade 2-3 neurotoxicity was observed in two (4%) patients and grade 2-3 fatigue in 14 (32%). Other toxicity was mild and no treatment-related death was reported. The combination of CPT-11 and P is a safe, well-tolerated, and active regimen for the treatment of patients with advanced NSCLC previously treated with a docetaxel-based front-line regimen.

The study compares docetaxel plus cisplatin (DC) and docetaxel plus gemcitabine (DG) regimens for the treatment of advanced non-small cell lung cancer (NSCLC). Patients were randomized to receive either the DC or the DG combination. They were stratified according to age, performance status (PS) and stage of disease. Three hundred seventeen patients entered the study. Of them, 162 received the DC regimen and 155 the DG regimen. There were no differences in the patients' characteristics between the two study arms. Preliminary analysis included 132 evaluable patients in the DC arm and 114 in the DG arm. Three complete responses (CR) (2.3%) and 39 partial responses (PR) (30%) were documented in the DC arm (response rate (RR) 32.3%; 95% CI 23.87-39.76%), whereas 1 CR (0.9%) and 38 PR (33%) were documented in the DG arm (RR: 33.9%; 95% CI 25.5-42.92%). No differences in the RR, response duration, time to tumor progression, overall survival and 1-year survival were observed between the two groups. Regarding toxicity, there were no significant differences in grade 3-4 anaemia and thrombocytopenia between the two arms. However, grade 3-4 neutropenia occurred in 40 patients (33%) treated with the DC regimen and in 31 patients (22%) treated with the DG regimen (P=0.01). Twenty-four (16%) patients in the DC arm and 20 (14%) in the DG arm developed febrile neutropenia. There was one death due to sepsis in each arm. Non-haematological toxicity was mild and equal in the two arms, with the exception of grade 3-4 nausea and diarrhoea, which were more frequent in the DC arm. In conclusion, preliminary results showed that the DG regimen was as effective as the DC regimen. The toxicity profile of the DG combination was relatively milder. Hence, cisplatin cannot be considered longer as a mandatory component of chemotherapy against NSCLC.
