[Show abstract][Hide abstract] ABSTRACT: Liposomal cisplatin was developed to reduce the systemic toxicity of cisplatin, particularly the nephrotoxicity, and it has been used in combination with other agents in pancreatic and head and neck cancers and non-small-cell lung cancer (NSCLC). Our objective was to compare the effectiveness of lipoplatin combined with paclitaxel versus cisplatin with paclitaxel in advanced non-squamous NSCLC.
During 2007-2010, 202 patients with non-squamous NSCLC (stage IIIB and IV) were recruited from the two participating institutions and divided into two arms: Arm A was treated with liposomal cisplatin 200 mg/m(2) combined with paclitaxel 135 mg/m(2) and Arm B with cisplatin 75 mg/m(2) in combination with paclitaxel 135 mg/m(2), repeated every 2 weeks. The number of cycles administered was 632 (Arm A) and 640 (Arm B), totaling 1,272.
A partial response was achieved by 59.22% of Arm A patients versus 42.42% of Arm B, and the difference was statistically significant (P 0.036). The median survival time in months was 10 for Arm A and 8 for Arm B (P 0.1551). After 18 months, the number of surviving patients was double for Arm A versus Arm B.
Liposomal cisplatin in combination with paclitaxel produces a statistically significantly higher response rate than cisplatin combined with paclitaxel in non-squamous NSCLC.

[Show abstract][Hide abstract] ABSTRACT: Liposomal cisplatin is a new formulation developed to reduce the systemic toxicity of cisplatin while simultaneously improving the targeting of the drug to the primary tumor and to metastases by increasing circulation time in the body fluids and tissues. The primary objectives were to determine nephrotoxicity, gastrointestinal side-effects, peripheral neuropathy and hematological toxicity and secondary objectives were to determine the response rate, time to tumor progression (TTP) and survival.
Two hundred and thirty-six chemotherapy-naive patients with inoperable non-small-cell lung cancer were randomly allocated to receive either 200 mg/m² of liposomal cisplatin and 135 mg/m² paclitaxel (arm A) or 75 mg/m² cisplatin and 135 mg/m² paclitaxel (arm B), once every 2 weeks on an outpatient basis. Two hundred and twenty-nine patients were assessable for toxicity, response rate and survival. Nine treatment cycles were planned.
Arm A patients showed statistically significant lower nephrotoxicity, grade 3 and 4 leucopenia, grade 2 and 3 neuropathy, nausea, vomiting and fatigue. There was no significant difference in median and overall survival and TTP between the two arms; median survival was 9 and 10 months in arms A and B, respectively, and TTP was 6.5 and 6 months in arms A and B, respectively.
Liposomal cisplatin in combination with paclitaxel has been shown to be much less toxic than the original cisplatin combined with paclitaxel. Nephrotoxicity in particular was negligible after liposomal cisplatin administration. TTP and survival were similar in both treatment arms.

[Show abstract][Hide abstract] ABSTRACT: The present study involves non-small cell lung (NSCLC) cancer patients with brain metastases, who were treated with radiation therapy, and our aim was to determine response rate and survival. A total of 167 patients were recruited, 155 (125 male, 30 female) of whom were evaluable. Performance status was 0-2 and histology or cytology included 66 (42.58%) adenocarcinomas, 62 (40.00%) undifferentiated and 27 (17.42%) squamous cell carcinomas. The stage of disease at diagnosis was IIIA-B in 92 (59.35%) patients and IV in 63 (40.65%). All patients had whole brain irradiation (3 Gy x 5 days/week for 2 weeks to a total dose of 30 Gy), which was performed by a linear accelerator and a 6-MV photon beam. Objective response was observed in 59/155 (38.06%) patients with 17 (10.97%) complete and 42 (27.09%) partial responses, and median survival of 5 months for all patients [95% confidence interval (CI) 3.9-6.1]. Responders had statistically significant longer survival than non-responders. Although responders represented less than half of our patients with NSCLC and brain metastases, they had significantly longer survival.
[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to determine the efficacy of paclitaxel (PCT) combined with vinorelbine (VRL) in adenocarcinoma of the lung.
Untreated inoperable patients with metastatic disease were enrolled and underwent front-line treatment with a new combination as follows: a 30-minute infusion of VRL at a dose of 25 mg/m2 followed by a 3-hour infusion of PCT 135 mg/m2. Chemotherapy was repeated every 2 weeks with the intention of administering 9 cycles.
Fifty-four out of 58 enrolled patients were assessable; the median age was 63 years (range 48-81). All patients were chemotherapy-naïve and all had histologically- or cytologically- confirmed adenocarcinoma. Twenty-seven patients (50%) responded: 5 with complete response (9.3%) and 22 with partial response (40.7%); 17 patients had stable disease (31.5%) and 10 showed disease progression (18.5%). Median response duration was 6 months (range 2-14.5) and median survival was 10 months (range 2-35+). The main adverse reaction was myelotoxicity in 87% of the patients, of whom only 8 (14.8%) had grade 4 neutropenia which in 4 cases (7.4%) was febrile. No patient required dose reduction, but treatment was postponed by one week in 4 patients a total of nine times. Patients received 98.6% of the planned dose.
The PCT and VRL combination is an active first-line treatment for lung adenocarcinoma. These two cytotoxic drugs produce acceptable toxicity when repeated every 2 weeks.
