[High-dose ifosfamide in patients with stage IV non-small cell lung cancer: phase II trial from the Groupe français de pneumo-cancérologie (GFPC)].

PURPOSE: To assess the toxicity and efficacy of high dose ifosfamide in stage IV NSCLC. METHODS: In a previous trial, we have determined maximum tolerated dose for 3-days ifosfamide treatment by 3-weeks schedule as 9 g/m2 according to hematologic tolerance. We therefore set up a phase II to study the toxicity and efficacy of this schedule in chemotherapy naive metastatic NSCLC. Ifosfamide (+ mesna 1 g/m2) was administered by a two hour infusion (3 g/m2) for three days every three weeks. Patients received three mesna bolus infusions (1 g/m2) at 4, 8 and 12 hours after the end of ifosfamide infusion. Antitumoral efficacy was performed after 2 cycles and treatment could be pursued for responding patients until disease progression. From september 1995 to January 1997, 31 patients have been included in this study. Median age was 60.7 years +/- 1.33 (41-70) for 27 males and 4 females. Patients (pts) presented metastases in lung for 10 pts, bone for 10 pts, liver for 6 pts, adrenal for 4 pts and multiorgan metastatic localisation for 1 patient. Seven patients were unassessable: 1 lost for follow-up, 1 sudden death, 5 treatment interruptions before evaluation time and 3 toxic deaths (9.6%). TOXICITY: neutropenia grade 4 (10 pts and 1 death), cardiotoxicity grade 4 (1 pt) and 2 deaths following neurotoxicity grade 4. We achieve 4 partial responses (13%, 95CI: 3.6-29.8), 10 progressive diseases (32.3%, 95CI: 16.7-51.4) and 10 stabilizations (32.3%, 95CI: 16.7-51.4). Median response duration was 91 days +/- 55 d. Median survival was 9.3 months, e.g. 280 days (8-863). Overall survival at one year is 48%. CONCLUSION: This modality of high dose ifosfamide is as effective as standard monotherapy schedules in stage IV NSCLC. Unexpected toxicities particularly hematological ones could be due to a short duration of fractionated treatment. Results in term of survival leads us to further evaluate ifosfamide monotherapy treatment on a 5-day schedule basis.

[Acute diffuse interstitial pneumopathy following docetaxel (Taxotère). Apropos of 2 cases].

Docetaxel, a new chemotherapeutic agent, has demonstrated activity in non-small cell lung cancer and breast cancer. Toxicities associated with treatment using docetaxel include hypersensitivity reactions and fluid retention, which can be prevented by pretreatment with corticosteroids. We describe herein two cases of acute interstitial pneumonitis after administration of docetaxel to patients suffering from metastatic non-small cell lung cancer. A pulmonary toxicity of docetaxel from an hypersensitivity reaction is likely because of symptoms course, radiological demonstration of an interstitial pneumonitis, lack of an infectious etiology and of clinical response to antibiotic treatment, and rapid recovery with corticosteroids. This unusual pulmonary toxicity has been rarely described with docetaxel, as transient pulmonary infiltrates have been observed during treatment with paclitaxel. The possibility of an hypersensitivity pneumonitis must be taken into account when a patient with docetaxel treatment presents pulmonary infiltrates.

[Chemotherapy of small cell bronchogenic carcinoma in a patient on hemodialysis for chronic renal failure. Apropos of a case].

Optimal dosage for chemotherapy administered to patients on chronic hemodialysis remains a difficult question. We report the case of a patient with chronic renal failure on hemodialysis for 9 years who was treated for small-cell lung cancer. The chemotherapy protocol combined carboplatin and etoposide at doses adapted to creatinine clearance. Tumor regression was observed after 6 cycles without major intolerance.

Carboplatin as radiosensitizer in non-small cell lung cancer after cisplatin containing chemotherapy. A phase I study of a groupe francais de pneumo-cancerologie (G.F.P.C.).

A Phase I trial of carboplatin therapy was performed on patients with locally advanced non-small cell lung cancer who had been previously treated with cisplatin, mitomycin and a vinca aklaloïd. This was administered as a daily bolus infusion or as a continuous infusion for 6 weeks with concurrent daily thoracic radiation. All patients had to be objective responders or to show no change after chemotherapy. The carboplatin was started at 10 mg/m2 per day, and increased to 15 mg/m2 per day and 20 mg/m2 per day, if treatment was feasible in successive cohorts of at least six patients. The radiation therapy consisted of 62-66 Gray on the tumor and the ipsilateral mediastinal nodes, 50 Gray on the mediastinum and 40-45 Gray on the supraclavicular lymph nodes. Twenty-nine patients took part in this study. Thrombocytopenia was the principal dose-limiting toxicity, with 15 mg/m2 per day of bolus or continuous infusion. Other toxicities included a fall in haemoglobin level, a fall in white-blood cell count, nausea and vomiting. The median survival time was 12 months, but the response rate cannot be determined among patients selected on the basis of response to chemotherapy. The recommended Phase II dose for patients previously treated with cisplatin containing chemotherapy, is 10 mg/m2 per day of either a bolus or continuous infusion.

Multicenter randomized trial comparing cisplatin-mitomycin-vinorelbine versus cisplatin-mitomycin-vindesine in advanced non-small cell lung cancer. 'Groupe Français de Pneumo-Cancérologie'.

The study was designed to evaluate the value of vinorelbine in a cisplatin-mitomycin-vinca alkaloid regimen for treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC). A group of 227 patients with inoperable NSCLC in stage III (58%) or stage IV (42%) were included in this randomized multicenter trial comparing a reference regimen (VDS group, n = 113) cisplatin (120 mg/m2 on day 1, day 29 and day 71), mitomycin (8 mg/m2 on day 1, day 29 and day 71) and vindesine (3 mg/m2/week for 5 weeks and then every 2 weeks up to the 15th week) to a cisplatin-mitomycin-vinorelbine combination (VNB group, n = 114), with cisplatin and mitomycin at the same doses, and vinorelbine 25 mg/m2/week for 16 weeks. The objective response rate (evaluated at 17th week) was 17% in the VDS group and 25% in the VNB group (P = 0.15). Median survival was 33.4 weeks and 34.5 weeks in the VDS and VNB arms, respectively. Overall survival duration was not significantly different between the two arms (logrank test, P = 0.20) despite a trend to an increased survival in the VNB group. This essentially benefited the patients with stage III disease with a clear-cut lengthening of median (45.9 vs. 33.4 weeks) and 1 year survival (44.6% vs. 26.2%, P < 0.05) in favor of the VNB group. Nevertheless, there was no significant difference in overall survival (logrank, P = 0.13). Survival duration of the patients with stage IV disease was comparable in the two arms (logrank test, P = 0.90). Grade 3 or 4 neutropenia was found in 61% and 87% of the VDS and VNB groups, respectively (P < 0.01). Grade 2-4 peripheral neuropathy was observed in 23% of the patients in the VDS group and in 6% of the patients in the VNB group (P < 0.01). Replacement of vindesine by vinorelbine in a cisplatin-mitomycin-vinca alkaloid chemotherapeutic regimen did not lead to a significant improvement in objective response rate or in duration of survival. There was a reduction in neurotoxicity at the expense of an increased hematologic toxicity. However, for patients with stage III disease there was an increase in 1 year survival with the vinorelbine combination.

[Small-cell carcinoma of the trachea in a 27-year-old patient].

A rare small-cell carcinoma of the trachea was observed in a 27 year-old man. Treatment included chemotherapy and radiotherapy as for bronchogenic small cell carcinomas. This treatment regimen led to complete but temporary remission. The patient died 4 months after the end of the treatment due to multiple cerebral metastases.

[Small cell bronchial cancer in a 17-year-old young man].

We report a case of small cell lung cancer in a 17 year-old man. He was admitted to our unit suffering from a two month history of pain left shoulder. Chest X-rays showed a large round mass in the left upper lobe. The chest CT scan revealed a tumor with evidence of first left rib involvement. Histological examination, after surgical biopsy revealed small cell carcinoma, confirmed by two independent pathological physicians. Small cell lung carcinoma is very rare in the under 20 year age group and we compare this case with other types of lung cancer in young patients described in the literature.

[Rhabdomyosarcoma of the thoracic wall in an adult. Apropos of a case].

Rhabdomyosarcoma is a malignant tumour generally observed in children or adolescents; thoracic localization is rare. The authors report a case of embryonary rhabdomyosarcoma of the thoracic wall in a 36-year-old subject. Pathology examination of surgical specimens confirmed the diagnosis. Treatment included surgical exeresis together with pre- and post-operative chemotherapy combining doxorubicine (40 mg/m2/cycle), ifosfamide (6 g/m2/cycle) and dacarbazine (900 mg/m2/cycle). Local recurrence, requiring radiotherapy, was observed a few months later and led to the patient's death after a 9-month clinical course.

[Inoperable brain metastases from bronchogenic cancers. Value of combined chemotherapy with cisplatin and 5 fluorouracil].

We report the results of a combined of chemotherapy with CDDP and 5 FU repeated every 3 weeks in sixteen men (age range 31-73 years) with brain metastases. CT was performed after 2, 4 and 6 cycles to assess efficiency. Response was considered complete when no lesion was found on the CT scan and partial when the lesion shrunk to least half its the total volume. After two cycles, the response rate was 8/16 (50%). Treatment toxicity was mild with only one case of severe but reversible myelotoxicity (grade III). CDDP and 5 FU combined chemotherapy can be a useful treatment for brain metastasis of lung carcinoma.

[Chemotherapy with cisplatin and 5-fluorouracil in inoperable brain metastases of bronchopulmonary cancers].

Chemotherapy is not a common treatment for cerebral metastases. The authors report results of combination chemotherapy with cisplatin (CDDP) and fluorouracil (5-FU). Sixteen men (age range 31-73 years) with brain metastases were treated with CDDP 20 mg/m2/day in continuous infusion for 5 days (d 1-5) and 5-FU 1 g/m2/day in continuous infusion for 4 days (d 1-4), and the treatment schedule repeated every 3 weeks. A brain computerized tomography after 2, 4 and 6 cycles was performed to assess efficacy. It was considered that complete response was achieved if no lesion was found on the CT scan, and partial response if at least half of the total volume had decreased. After 2 cycles, the response rate was therefore 8/16 (50%). Treatment toxicity was very mild with only 1 case of severe but reversible myelotoxicity (grade III). It is concluded that chemotherapy combination with CDDP and 5-FU is a useful treatment for brain metastasis of lung carcinoma.

[Value of ipratropium (Atrovent) in the treatment of chronic obstructive lung diseases in myasthenic patients treated with anticholinesterase agents. Apropos of a case].

We report a case of myasthenia gravis occurring in a 70-year old patient with old chronic bronchitis. Anticholinesterase therapy led to an increase in respiratory symptoms, but relief was obtained with inhaled ipratropium. The activity of this drug was confirmed by spirography. This clinical finding is compared with similar data found in the literature.
