          Abstract

          Background

          The aim of the study was to investigate if first-line chemotherapy improves total survival time in non-small-cell lung cancer (NSCLC) patients complicated with severe to very severe COPD.

          Materials and methods

          This retrospective observational clinical study included 267 consecutive NSCLC patients with COPD complications at the Department of Respiratory and Critical Care Medicine of Tianjin Chest Hospital between January 2009 and January 2018. Sixty-nine evaluable patients were included. The clinical characteristics, toxicity profile, objective response rate, and prognosis were analyzed and compared between patients receiving and those not receiving chemotherapy.

          Results

          Forty-five and 24 patients received first-line chemotherapy plus supportive care and supportive care alone, respectively. Kaplan–Meier curves showed that patients receiving chemotherapy had a statistically significant 6-month longer median overall survival (OS) than that of patients receiving supportive care alone (14.0, 95% CI: 8.5–19.5 vs 8.0, 95% CI: 6.4–9.6, respectively) (chi 2=8.857, P=0.003). In the multivariate Cox proportional hazard model adjusted for the most relevant variables, the adjusted hazard ratio (HRadj) differed significantly for the receipt of chemotherapy (HRadj=0.4464, 95% CI: 0.2495–0.7988; P=0.0066) but not for gender (HRadj=0.8527, 95% CI: 0.4461–1.6298; P=0.6297), age (HRadj=1.0021, 95% CI: 0.9609–1.0451; P=0.9214), histology (HRadj=1.4422, 95% CI: 0.6959–2.9889; P=0.3247), cancer stage (HRadj=1.9098, 95% CI: 0.8607–4.2375; P=0.1116), performance status score (HRadj=1.5155, 95% CI: 0.7523–3.0529; P=0.2446), lung function (HRadj=1.3856, 95% CI: 0.7149–2.6857; P=0.3341), or respiratory symptoms (HRadj=1.0518, 95% CI: 0.6032–1.8342; P=0.8586). Patients with grade 3/4 adverse reactions accounted for 29% (13/45) of the chemotherapy group.

          Conclusion

          The results indicated that chemotherapy may improve the OS of NSCLC patients with severe to very severe COPD.

          PARAMOUNT: Final overall survival results of the phase III study of maintenance pemetrexed versus placebo immediately after induction treatment with pemetrexed plus cisplatin for advanced nonsquamous non-small-cell lung cancer.

          In the phase III PARAMOUNT trial, pemetrexed continuation maintenance therapy reduced the risk of disease progression versus placebo (hazard ratio [HR], 0.62; 95% CI, 0.49 to 0.79; P < .001). Here we report final overall survival (OS) and updated safety data. In all, 939 patients with advanced nonsquamous non-small-cell lung cancer (NSCLC) received four cycles of pemetrexed-cisplatin induction therapy; then, 539 patients with no disease progression and Eastern Cooperative Oncology Group performance status 0 or 1 were randomly assigned (2:1) to maintenance pemetrexed (500 mg/m(2) on day 1 of 21-day cycles; n = 359) or placebo (n = 180). Log-rank test compared OS between arms as measured from random assignment (α = .0498). The mean number of maintenance cycles was 7.9 (range, one to 44) for pemetrexed and 5.0 (range, one to 38) for placebo. After 397 deaths (pemetrexed, 71%; placebo, 78%) and a median follow-up of 24.3 months for alive patients (95% CI, 23.2 to 25.1 months), pemetrexed therapy resulted in a statistically significant 22% reduction in the risk of death (HR, 0.78; 95% CI, 0.64 to 0.96; P = .0195; median OS: pemetrexed, 13.9 months; placebo, 11.0 months). Survival on pemetrexed was consistently improved for all patient subgroups, including induction response: complete/partial responders (n = 234) OS HR, 0.81; 95% CI, 0.59 to 1.11 and stable disease (n = 285) OS HR, 0.76; 95% CI, 0.57 to 1.01). Postdiscontinuation therapy use was similar: pemetrexed, 64%; placebo, 72%. No new safety findings emerged. Drug-related grade 3 to 4 anemia, fatigue, and neutropenia were significantly higher in pemetrexed-treated patients. Pemetrexed continuation maintenance therapy is well-tolerated and offers superior OS compared with placebo, further demonstrating that it is an efficacious treatment strategy for patients with advanced nonsquamous NSCLC and good performance status who did not progress during pemetrexed-cisplatin induction therapy.

              Randomized, multinational, phase III study of docetaxel plus platinum combinations versus vinorelbine plus cisplatin for advanced non-small-cell lung cancer: the TAX 326 study group.

              To investigate whether docetaxel plus platinum regimens improve survival and affect quality of life (QoL) in advanced non-small-cell lung cancer (NSCLC) compared with vinorelbine plus cisplatin as first-line chemotherapy. Patients (n = 1,218) with stage IIIB to IV NSCLC were randomly assigned to receive docetaxel 75 mg/m2 and cisplatin 75 mg/m2 every 3 weeks (DC); docetaxel 75 mg/m2 and carboplatin area under the curve of 6 mg/mL * min every 3 weeks (DCb); or vinorelbine 25 mg/m2/wk and cisplatin 100 mg/m2 every 4 weeks (VC). Patients treated with DC had a median survival of 11.3 v 10.1 months for VC-treated patients (P =.044; hazard ratio, 1.183 [97.2% confidence interval, 0.989 to 1.416]). The 2-year survival rate was 21% for DC-treated patients and 14% for VC-treated patients. Overall response rate was 31.6% for DC-treated patients v 24.5% for VC-treated patients (P =.029). Median survival (9.4 v 9.9 months [for VC]; P =.657; hazard ratio, 1.048 [97.2 confidence interval, 0.877 to 1.253]) and response (23.9%) with DCb were similar to those results for VC. Neutropenia, thrombocytopenia, infection, and febrile neutropenia were similar with all three regimens. Grade 3 to 4 anemia, nausea, and vomiting were more common (P <.01) with VC than with DC or DCb. Patients treated with either docetaxel regimen had consistently improved QoL compared with VC-treated patients, who experienced deterioration in QoL. DC resulted in a more favorable overall response and survival rate than VC. Both DC and DCb were better tolerated and provided patients with consistently improved QoL compared with VC. These findings demonstrate that a docetaxel plus platinum combination is an effective treatment option with a favorable therapeutic index for first-line treatment of advanced or metastatic NSCLC.
