Oxaliplatin plus vinorelbine in advanced non-small-cell lung cancer: final results of a multicenter phase II study.

BACKGROUND: Oxaliplatin and vinorelbine are both active agents against non-small-cell lung cancer (NSCLC). In a previous phase I trial, we showed that oxaliplatin (130 mg/m2, day 1) and vinorelbine (26 mg/m2/day, days 1 and 8) can be safely combined when given every 21 days. We completed the evaluation of this new platinum-based doublet in advanced NSCLC patients in a multicenter phase II study. PATIENTS AND METHODS: Twenty-eight chemotherapy-naïve patients (22 men and six women: median age 58 years, range 33-70), including 20 with stage IV disease, received this out-patient combination, with 5-hydroxytryptamine-3-receptor agonists as the only prophylactic measure. RESULTS: A total of 117 cycles were given, for a median of three per patient (range 1-8). Of 26 eligible patients, nine achieved a partial response (WHO criteria), giving an objective response rate of 35% [95% confidence interval (CI) 17% to 56%]. The median progression free survival was 5.0 months (95% CI 3.1 to 6.9), median overall survival was 9.8 months (95% CI 2.2 to 17.5) and the 1-year survival rate was 37%. Neutropenia was the principal toxicity, grade 4 occurring in 11 patients (39%) and 25 cycles (22%). Four patients (14%) experienced one episode of febrile neutropenia each. Acute oxaliplatin-related neurosensory toxicity was prevalent, but was mild to moderate in the majority of patients (82%) and reversible. Grade 1/2 vomiting (65% of patients) and diarrhea (32% of patients) were easily managed. CONCLUSIONS: The oxaliplatin-vinorelbine doublet is a safe and active out-patient combination. It may represent an interesting alternative in the management of patients with NSCLC, and serve as a new doublet to which other active agents could be added.

Phase I/II study of escalating doses of vinorelbine in combination with oxaliplatin in patients with advanced non-small-cell lung cancer.

PURPOSE: Oxaliplatin is a platinum compound active in non-small-cell lung cancer (NSCLC) patients, and vinorelbine (VNB) is an active reference agent. This phase I/II study was performed to determine the dose-limiting toxicity (DLT), the maximum-tolerated dose (MTD), and the recommended dose (RD) of a VNB/oxaliplatin combination given to previously untreated patients with advanced NSCLC. PATIENTS AND METHODS: Oxaliplatin was given at the fixed dose of 130 mg/m2 (2-hour intravenous [IV] infusion) on day 1. VNB was administered on days 1 and 8 (10-minute IV infusion), with doses starting at 22 mg/m2/d and escalated by 2 mg/m2 increments until MTD. Treatment was repeated every 3 weeks. No special hydration measures or prophylactic granulocyte colony-stimulating factors were used. RESULTS: Twenty-seven patients (20 men, 7 women) received 110 cycles total at six different VNB dose levels. Neutropenia was the DLT. Although no patient experienced DLT at the highest dose level (32 mg/m2/d), multiple treatment delays (54% of cycles) and dose reductions (34% of cycles) were required at this dose level. Others toxicities were mainly limited to grade 1 peripheral neuropathy and grade 1/2 nausea/vomiting. The relative dose-intensity of administered VNB from dose levels 3 to 6 (26 to 32 mg/m2) remained stable, whereas grade 3/4 neutropenia increased. All patients were assessable for activity; there were 10 objective responses, including one complete response (37% response rate). CONCLUSION: The present combination can be safely administered in an outpatient setting. The RD is VNB 26 mg/m2 days 1 and 8 with oxaliplatin 130 mg/m2 day 1 every 3 weeks.

Phase II study of oxaliplatin in poor-prognosis non-small cell lung cancer (NSCLC). ATTIT. Association pour le Traitement des Tumeurs Intra Thoraciques.

The aim of this phase II study was to determine the antitumour activity and safety of trans-1-diaminocyclohexane-platinum (oxaliplatin) in previously untreated advanced non-small cell lung cancer (NSCLC) patients. 33 patients with unresectable and measurable NSCLC were entered into this phase II study between January 1992 and January 1994. Patients had either locoregional disease with performance status 2 (19 patients) or a stage IV disease (14 patients). Oxaliplatin (130 mg/m2) was given on an out-patient basis (2-h infusion, every 21 days) without hydration. Response was assessed after every two courses. One hundred courses were administered, with a mean of three courses per patient (range 1-12). All patients were evaluable for response; 1 had a complete response, and 4 a partial response (overall response rate 15%, 95% confidence interval 5.1-31.9%). The median response duration was 5.9 months. All cycles (n = 100) were evaluable for toxicity assessment. Transient reversible, cold-related finger dysesthesias occurred in 29 patients, but were mild, and disappeared in most cases within a few days. We observed brief episodes of pharyngolaryngeal discomfort (8 patients, 11 episodes) accompanied in 4 cases (3 patients), by transient episodes of inspiratory stridor, leading 2 patients to treatment withdrawal. We conclude that oxaliplatin has activity in poor-prognosis NSCLC and that this treatment is feasible in out-patients; the absence of renal and haematological toxicity makes this drug a good candidate for further evaluation in NSCLC.

[Two new cases of autonomous ectopic goiter]. / Deux nouveaux cas de goitre ectopique autonome.

We observed two cases of autonomous intrathoracic goiter in patients with no past history of thyroidectomy. After resection, the surgical specimens confirmed the non-malignant nature of the goiter. We discuss the literature on management of autonomous intrathoracic goiter.

Extensive small-cell lung cancer. A randomized comparison of two chemotherapy programs with early crossover in instances of failure. Association pour le Traitement des Tumeurs Intra-Thoraciques (ATTIT).

Two chemotherapy regimens for patients with extensive small-cell lung cancer were prospectively compared in a randomized multicentric trial with crossover. Every four weeks, 60 consecutive previously untreated patients received either DPE (doxorubicin, cisplatin and etoposide), or CIV (carboplatin, ifosfamide and vincristine) with crossover as soon as progression or end of response were observed. Pretreatment characteristics were similar in the two groups. Fifty-seven patients were evaluated for response. The response rate was higher with the DPE regimen both in first-line (for DPE: response rate 62% (18/29), including 17% (5/29) of complete response (CR), and for CIV: response rate 29% (8/28) with no CR, p < 0.02) and in second-line after crossover (for DPE: response rate 45% (9/20) including 5% (1/20) of CR, and for CIV response rate 0%, p < 0.02). Major toxicities were equally frequent in both groups. No significant difference was found between median survival times (9.7 months for the DPE group and 10.4 months for the CIV group). We conclude that: 1) DPE is a more active regimen than CIV, both in first- and second-line; 2) no alternating scheme may be considered with these two combinations. Of particular note is the similar median survival times in the two groups, contrasting with the different activities of the two regimens.

Influence of pretreatment clinical characteristics on the response rate to mitomycin/vindesine/cisplatin (MVP) in unresectable non-small cell lung cancer. ATTIT (Association pour le Traitement des Tumeurs Intra-Thoraciques).

The authors report their experience with the MVP (mitomycin/vindesine/cisplatin) regimen of the Memorial Sloan-Kettering Cancer Center (MSKCC) which showed the highest response rate in non-small cell lung cancer (NSCLC). The aim was to respect the original reported schedule to appreciate its activity, because the same drug combination with dose and schedule variations used by other investigators has failed to reproduce the original report results. 82 consecutive previously untreated patients with unresectable and/or metastatic NSCLC received mitomycin (8 mg/m2 days 1, 29, 71), vindesine (3 mg/m2, days 1, 8, 15, 22, 29, 43, 57, 71) and cisplatin (120 mg/m2, days 1, 29, 71), with evaluation on day 71. 24 objective responses were noted (29%) (2 complete response/22 partial response) (95% CI 19%-39%), without differences according to histology. Differences in median survival were noted according to the performance status and type of response. Overall survival rates in responding patients were similar to those noted with the original schedules. Analysis of selection criteria showed that there were more patients with bone (P less than 0.01) or liver metastases (P less than 0.05), less women (P less than 0.001) and less adenocarcinoma (P less than 0.001) than the MSKCC trial. A dose intensity analysis showed only a minimal difference in the average weekly doses of vindesine (10% lower than MSKCC trial: 1.8 mg/m2 vs. 2.25 mg/m2). Disease improvement, a subjective response criterion used in the MSKCC trial, was probably underestimated in the current study. We conclude that the potential benefit of chemotherapy with a three-drug combination in NSCLC is greatest in patients with stage IIIa and IIIb disease or stage IV disease with a good performance status and a low metastatic volume.

[Pulmonary infection caused by a rare mycobacterium, Mycobacterium malmoënse]. / Infection pulmonaire due à une mycobactérie rare Mycobacterium malmoënse.

The present case report is on a patient treated for tubercle in 1949 by an artificial pneumothorax. Thirty three years after the initial illness some radiological changes occurred suggesting a recurrence, especially as a bacteriological examination showed the presence of acid-alcohol fast bacilli on direct smear. Triple therapy (Isoniazid, Rifampicin, Streptomycin) was then prescribed, and was followed by a radiological improvement, even though the sputum remained positive. After multiple seedings, it was possible to isolate from 11 tubes and 2 expectorations a rare strain of mycobacterium: mycobacterium malmoense. The present observation seems to be the first indisputable French case of infection by this bacterium. From the opportunity presented by this observation the bacteriological characteristic of this mycobacterium, as well as the clinic aspects of the infection are discussed.

[Modification during treatment of the rate of acetylation of isoniazide clinically or biologically detectable hepatic damage (author's transl)]. / Modification, en cours oe traitement, de la vitesse d'acétylation de l'isoniazide sans atteinte hépatique décelable.

The rate of acetylation of isoniazid is usually constant in a given subject. The authors report here a case where despite an adjusted initial dose there was a decrease in the rate of acetylation during treatment with INH-rifampicin and ethambutol, without hepatic involvement but accompanied by retrobulbar optic neuritis. The role of ethambutol and/or an overdose of isoniazid are discussed. The technique for its estimation is also described.
