These data show that carboplatin plus vinorelbine is an active and well-tolerated regimen in extensive SCLC. In view of the activity, low toxicity, and ease of administration, it may be a reasonable alternative to more toxic cisplatin-containing regimens.
Fifty-three cases of metastatic pleural effusion (30 haemorragic and 23 serofibrinous) were treated with 4 mg of Corynebacterium parvum (CP) injected weekly into the pleural cavity after total thoracentesis. Of the 53 effusions, 24 were metastases from lung cancer and 29 from breast cancer. Complete response (CR) was assessed as total resolution of pleural effusion after explorative thoracentesis. The results were as follows: 15 CR after two injections of CP, 30 CR after three, and 5 CR after the fourth administration. Three of 53 cases could not be evaluated because of early death. Of the 30 clearly haemorragic effusions, 25 turned into serofibrinosis after the first intrapleural injection of CP and the other five after the second. These findings indicate that intracavitary CP is the most adequate treatment for the control of neoplastic pleural effusion because it induces a significant clinical improvement with milder side effects with respect to other drugs and/or physical agents commonly used.
Two hundred sixteen patients with unresectable non-small cell lung carcinoma were randomly allocated to receive etoposide (120 mg/m2, days 1-3) either alone or in combination with high-dose cisplatin (60 mg/mz, days 1-2). The patients' distribution and characteristics were similar in the two treatment arms. The objective response rate for etoposide was 7% versus 25.8% for etoposide plus cisplatin ( P < 0.005). Median progression-free survival in etoposide arm was 3.5 months versus 5 months in the combination arm ( P = 0.43). The median survival time for etoposide was 6 months compared with 8 months for etoposide combined with cisplatin (P = 0.87). Significantly more nausea/vomiting (P < 0.005), serum creatinine elevation ( P < 0.0051, hearing loss and/or tinnitus ( P < 0.005), peripheral neuropathy ( P < 0.005), leukopenia ( P < 0.025), and anemia ( P < 0.005) occurred in the etoposide plus cisplatin arm. No statistically significant difference was recorded between the two arms in terms of performance status changes. In conclusion the addition of high-dose cisplatin to single-agent etoposide significantly increases the chance of obtaining tumor response in advanced non-small cell lung cancer at the cost of an increased toxicity without any significant long-term impact on survival and progression-free survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
