Phase I study of paclitaxel (Taxol) plus vinorelbine (Navelbine) in patients with untreated stage IIIb and IV non-small cell lung cancer.

A dose escalation study of paclitaxel in combination with vinorelbine was conducted in 21 patients with previously untreated stage IIIb or IV non-small cell lung cancer (NSCLC). All three patients treated with the initial dose of paclitaxel 135 mg/m(2) administered as a 1-h intravenous infusion and vinorelbine 25 mg/m(2) experienced dose-limiting toxicity (febrile neutropenia). After modification of the dosing schedule, the MTD of paclitaxel was found to be 115 mg/m(2) when combined with vinorelbine 20 mg/m(2) on day 1, followed by vinorelbine 20 mg/m(2) on day 5.

Impact of UFT on tumoral TS and DPD levels in colorectal cancer.

This was an open lable, pilot translational clinical pharmacology study of a brief (7 day) course of UFT, 300 mg/m2/day, in combination with leucovorin, 90 mg/day, in six patients with newly diagnosed advanced colorectal cancer. The primary objectives of the study were to examine the impact of this treatment course on the UFT targets which are thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD). The rate of tumoral TS inhibition after the 7-day UFT treatment sequence varied from 5% up to 31%.

Synergistic antitumoral activity of combined UFT, folinic acid and oxaliplatin against human colorectal HT29 cell xenografts in athymic nude mice.

This study was designed to assess the inhibition of tumor growth by oxaliplatin combined with UFT and folinic acid (FA). Growth inhibition was studied in nude mice transplanted with human colorectal HT29 tumor cell xenografts and treated for 28 days with oral UFT (20 mg/kg/day) and FA (4 mg/kg/day), i.p.

Carboplatin plus paclitaxel in the first-line treatment of advanced ovarian cancer: preliminary results of a phase I study.

This phase I trial was designed to determine the maximum tolerated dose of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given as a 3-hour infusion in combination with carboplatin (400 mg/m2) as first-line chemotherapy for stage IIIC/IV ovarian adenocarcinoma. After premedication, paclitaxel was infused over 3 hours, followed by carboplatin infused over 30 minutes on day 1 of a 28-day cycle (group 1, with 28 patients accrued and 150 evaluable cycles) or on day 1 of a 21-day cycle (group 2, with 16 patients accrued and 55 evaluable cycles). Dose-limiting toxicities assessed after the first course included grade 4 neutropenia lasting longer than 7 days, febrile grade 4 neutropenia requiring intravenous antibiotics, grade 4 thrombocytopenia, mucositis greater than grade 2 for more than 7 days, grade > or = 3 nonhematologic toxicity (excluding alopecia, vomiting, and muscular pain), no hematologic recovery on day 42 (for group 1) or on day 35 (for group 2), neurotoxicity above grade 2, and persistence of nonhematologic toxicity (excluding alopecia, nausea/vomiting, and musculoskeletal pain) grade > or = 2 at scheduled re-treatment.

[Is there a place for chemotherapy in the initial treatment of cervical cancer? Review of the literature].

Despite their high efficiency in treating cancer of the uterine cervix, surgery and radiotherapy can not cure (local and/or metastatic disease) a certain number of patients with initially adverse risk factors, mostly local or regionally advanced cervical carcinoma (stage III-IVA) or early stage (IB-II) disease with bulky primary lesion or involved regional nodes. Since the 1980s, many investigators have tried to determine whether or not there is any benefit in introducing chemotherapy earlier in the therapeutic plan for these patients: either initially before surgery or radiotherapy (neoadjuvant), or during radiotherapy (concurrent), or after local treatment (adjuvant). In this review we seek to sum up the published data available and to determine if at present there is a place for chemotherapy in the initial treatment of cervical cancer.
