Randomized multicentric phase II study of carboplatin/gemcitabine and cisplatin/vinorelbine in advanced non-small cell lung cancer GFPC 99-01 study (Groupe français de pneumo-cancérologie).

PURPOSE: To evaluate the efficacy and safety of gemcitabine and carboplatin in the treatment of previously untreated patients with advanced non-small cell lung cancer (NSCLC). METHODS: A randomized phase II study was conducted by the Groupe Français de Pneumo-Cancérologie (GFPC) in 15 centers. The patients were randomized in either arm A (GC): gemcitabine 1250 mg/m2 on days 1 and 8+carboplatin AUC 6 mg/(mLmin) on day 1; or in arm B (VP): vinorelbine 30 mg/m2 weekly+cisplatin 80 mg/m2 on day 1. Treatment cycles were repeated every 3 weeks. RESULTS: A total of 100 patients were randomized with stage IV or stage III NSCLC with malignant pleural effusion: 51 patients in arm A and 49 patients in arm B. A total of 190 cycles were administered in the GC arm and 172 cycles in the VP arm, with a median of four cycles per patient in each arm. The dose intensity was 84.9% for gemcitabine, 99.8% for carboplatin, 97.7% for cisplatin and 67.7% for vinorelbine. The objective response rates were 19.6% (95% CI, 9.8-33.1) for GC and 29.2% (95% CI, 17.0-44.1) for VP in an ITT analysis. The response duration was 169 days in arm A and 226 days in arm B. The TTP was similar with 140 days (GC) and 148 days (VP), respectively. Overall survival rates were 334 days in the GC combination and 304 days in the VP combination. Overall, the treatment was safe and toxicities observed were different in each arm: neutropenia was the most common toxicity in the VP treatment, whereas thrombocytopenia was more frequent in the GC combination. Anemia was similar in both arms. Non-haematologic toxicity was mild. One toxic death in arm A and three toxic deaths in arm B were observed. CONCLUSION: In terms of response rate, the gemcitabine-carboplatin combination was not efficient enough to allow further phase III study. Survival data are in the same range as the standard arm. This chemotherapy is feasible and may represent an alternative to a standard cisplatin-based regimen, allowing treatment in an outpatient setting.

Phase II trial of paclitaxel and carboplatin in metastatic small-cell lung cancer: a Groupe Français de Pneumo-Cancérologie study.

PURPOSE: To evaluate the efficacy and safety of paclitaxel and carboplatin in the treatment of previously untreated patients with metastatic small-cell lung cancer (SCLC). PATIENTS AND METHODS: Eligible patients were aged 18 to 75 years with an Eastern Cooperative Oncology Group (ECOG) score < or = 2 and life expectancy > or = 12 weeks. Paclitaxel (200 mg/m(2)) was infused over 3 hours, before carboplatin (area under the curve [AUC] 6; Calvert formula) infused over 1 hour, once every 3 weeks for six cycles maximum. Prednisolone, dexchlorpheniramine, and ranitidine were standard premedication. Response to treatment was assessed every two cycles, and nonresponding patients were withdrawn from the trial to receive standard chemotherapy. RESULTS: Of the 50 patients entering the study, 48 and 46 patients were assessable for toxicity and response, respectively. The overall response rate was 65%, with complete responses in three patients. Five patients had stable disease (11%) and 11 patients experienced progressive disease (24%). Median survival was 38 weeks, and median duration of response was 20 weeks. One-year survival was 22.5%. For a total of 232 cycles, grade 3 and 4 toxicity was 33% for neutropenia, 3.5% for thrombocytopenia, and 4% for anemia. Four patients had neutropenic fever (one toxic death). Nonhematologic toxicity was mainly grade 1 and 2 paresthesia (21% of patients); grade 3 myalgia/arthralgia was observed in 6.5% of patients. CONCLUSION: First-line chemotherapy with paclitaxel and carboplatin in metastatic SCLC achieved a response rate and survival similar to standard regimens. With 1-day administration and a tolerable toxicity profile, this combination merits further investigation.

Topotecan versus cyclophosphamide, doxorubicin, and vincristine for the treatment of recurrent small-cell lung cancer.

PURPOSE: Topotecan and cyclophosphamide, doxorubicin, and vincristine (CAV) were evaluated in a randomized, multicenter study of patients with small-cell lung cancer (SCLC) who had relapsed at least 60 days after completion of first-line therapy. PATIENTS AND METHODS: Patients received either topotecan (1.5 mg/m2) as a 30-minute infusion daily for 5 days every 21 days (n = 107) or CAV (cyclophosphamide 1,000 mg/m2, doxorubicin 45 mg/m2, and vincristine 2 mg) infused on day 1 every 21 days (n = 104). Eligibility included the following: bidimensionally measurable disease, Eastern Cooperative Oncology Group performance status of less than or equal to 2, and adequate marrow, liver, and renal function. Response was confirmed by blinded independent radiologic review. RESULTS: Response rate was 26 of 107 patients (24.3%) treated with topotecan and 19 of 104 patients (18.3%) treated with CAV (P = .285). Median times to progression were 13.3 weeks (topotecan) and 12.3 weeks (CAV) (P = .552). Median survival was 25.0 weeks for topotecan and 24.7 weeks for CAV (P = .795). The proportion of patients who experienced symptom improvement was greater in the topotecan group than in the CAV group for four of eight symptoms evaluated, including dyspnea, anorexia, hoarseness, and fatigue, as well as interference with daily activity (P< or =.043). Grade 4 neutropenia occurred in 37.8% of topotecan courses versus 51.4% of CAV courses (P<.001). Grade 4 thrombocytopenia and grade 3/4 anemia occurred more frequently with topotecan, occurring in 9.8% and 17.7% of topotecan courses versus 1.4% and 7.2% of CAV courses, respectively (P<.001 for both). Nonhematologic toxicities were generally grade 1 to 2 for both regimens. CONCLUSION: Topotecan was at least as effective as CAV in the treatment of patients with recurrent SCLC and resulted in improved control of several symptoms.

Docetaxel and concurrent radiotherapy after two cycles of induction chemotherapy with cisplatin and vinorelbine in patients with locally advanced non-small-cell lung cancer. A phase II trial conducted by the Groupe Francais de Pneumo-Cancerologie (GFPC).

CONTEXT: The most satisfactory treatment for patients with locally advanced non-small-cell lung cancer (NSCLC) is combination chemotherapy-radiotherapy (CT-RT). The optimal treatment modalities remain to be determined. OBJECTIVE: We conducted a multicenter phase II trial of the docetaxel-radiotherapy combination after induction chemotherapy with cisplatin-vinorelbine. The main endpoint was the objective response rate. PATIENTS AND METHODS: Patient with inoperable stage locally advanced NSCLC received induction chemotherapy consisting of two cycles of cisplatin 100 mg/m2 on D1 and vinorelbine 25 mg/m2 on D1, D8, D15 and D22. Patients with responses or stable disease then received concurrent RT-CT consisting of 25 mg/m2/week docetaxel and single-fraction radiotherapy (66 grays (Gy) in 33 fractions) over 6.5 weeks. RESULTS: Fifty-six patients were enrolled from 1 July 2000 to 31 December 2001. Sixteen patients left the trial after induction chemotherapy, eight for progression, five for toxicity, and two for intercurrent events. One patient underwent surgery after induction chemotherapy. In total, 40 of the 56 patients received RT-CT. Twelve (30%) of these 40 patients experienced grade III or IV pulmonary or esophageal toxicity. In the intention-to-treat analysis, the objective response rate was 46.4% (95% CI 33.0-60.2). The median time to progression was 6.2 months [1.1-26.0]. The median survival time was 13 months [0.3-44.9 months]. Nine patients progressed during RT-CT, six with brain metastases. CONCLUSION: Weekly docetaxel with concurrent radiotherapy, following chemotherapy is acceptable. The tumor response rate is moderate. Further trials are required to determine the risk-benefit relationship of this treatment schedule, and the possible benefit of adding other cytotoxic drugs.

[Use of 153Sm-EDTMP to relieve pain from bone metastasis in lung cancer]. / 153Samarium-EDTMP et contrôle de la douleur liée aux métastases osseuses des cancers bronchiques.

INTRODUCTION: The treatment of bone metastasis from lung cancer is palliative in nature with elimination of pain being the primary goal. Management is based on pharmacologicalmethods (steroids, morphine, and pamidronate) and radiotherapy. However, other treatments have been developed including the systemic radiopharmaceutical 153Sm-EDTMP. CASE REPORTS: We report data from 6 lung cancer patients with bone metastases treated with 153Sm-EDTMP. Demographic and therapeutic data, pain evaluation by visual analogue scale (VAS) and change in opioid analgesia requirements (expressed as intravenous morphine equivalent) as well as survival were studied. Pain associated with bone metastasis (median VAS = 8 [7-9], median morphine dose = 167 mg [100-800 mg]) did not significantly improve (median VAS after 153Sm-EDTMP = 8.5 [5-10], median morphine dose after 153Sm-EDTMP = 185 mg [30-2 200 mg]) in this group of patients. CONCLUSION: Our results combined with current data in the literature concerning the use of this treatment in the treatment of bone pain associated with metastatic lung cancer suggest that at present its use cannot be recommended outside the context of clinical of clinical trials.

Asthma and allergy to house-dust mites in populations living in high altitudes.

Do subjects living in high altitude where house-dust mites are known to be uncommon exhibit a lower prevalence of asthma and allergy to house-dust mites? To answer this question, we compared the prevalence rates of asthma and skin reactions to house-dust mites in two towns with contrasted environments: Marseille, located on the seashore, and Briançon, 1350 m in altitude. The study population consisted of a random sample of 4,008 people in Marseille and 1,055 people in Briançon. All subjects received a home questionnaire, and a sample of patients and asymptomatic subjects had a skin-prick test evaluation. The cumulative prevalence of asthma was equal to 4.1 percent in Marseille and 2.4 percent in Briançon, a difference which was significant (p = 0.01). The prevalence of positive skin tests to housedust mites in asymptomatic subjects was equal to 27.5 percent in Marseille and 10.2 percent in Briançon (p less than 0.001). This study supports the hypothesis that exposure to environmental factors may have a major influence on developing allergic diseases.

Usefulness of longitudinal evaluation of Cyfra 21-1 variations in advanced lung cancer monitoring.

To investigate the usefulness of Cyfra 21-1 as an indicator of therapy effectiveness and prognosis in advanced primary lung cancer, sixty-three patients were selected on the basis of a high Cyfra 21-1 serum level (> 3.3 ng/ml) at the time of diagnosis. Serial assays of Cyfra 21-1 were performed during the first three courses of chemotherapy among 63 patients. The serial-values were analysed according to response to treatment and overall survival. After three courses of chemotherapy, a 70% reduction under the initial marker's value or a return to normal was observed for 36 patients. Twenty-two (61%) of these patients presented an objective response to therapy, making Cyfra 21-1 a moderate indicator in terms of positive predictive value (PPV). However, a significant decrease of Cyfra 21-1 was observed in 88% (sensitivity) of the 25 objective responders. Cyfra 21-1 changes after one course of chemotherapy (61 patients) were not sufficient to predict the future response after three courses (sensitivity 52%, specificity 56%, PPV 45%). Among 30 clinical or radiological relapses, a 10% increase or a return upper reference limit in Cyfra 21-1 level was observed in 18 cases (sensitivity 60%, specificity 100%, PPV 100%). Survival data were available for 61 patients. No significant statistical difference (P > 0.05) was found between survival curves depending on a significant decrease of Cyfra 21-1 after the first course of chemotherapy. We can conclude that the only interest of serial Cyfra 21-1 assays may be the detection of relapse, where one observes a significant decrease of the marker correlated with an objective response to first treatment.

Phase I trial of gemcitabine and carboplatin in metastatic non-small-cell lung cancer: a Groupe Français de Pneumo-Cancérologie Study.

BACKGROUND: The purpose of this study was to determine the maximum-tolerated dose (MTD) and the dose-limiting toxicity (DLT) of the 21 days carboplatin plus gemcitabine regimen in previously untreated patients with stage IV non small-cell lung cancer (NSCLC). METHODS: At least three patients were entered at each dose level. The starting dose was carboplatin AUC 4 mg/ml per min (Area Under the Curve; Calvert formula) on day 1 and gemcitabine 750 mg/m(2) on days 1 and 8. Carboplatin was increased to AUC 5 (level 3, 4) then to AUC 6 (level 5-7). Gemcitabine was increased to 875 (level 2, 3), 1000 (level 4, 5), 1250 (level 6) and finally 1500 mg/m(2) (level 7). Twenty-nine patients were entered into this phase I study. RESULTS: At dose level 6, a DLT (grade 4 thrombocytopenia) was observed in one out of six patients. At dose level 7, no DLT was observed during the first course, so the MTD was not reached. During the second course, two out of four patients presented grade 4 thrombocytopenia. None of the five patients receiving two courses at level 6 presented a DLT, so this level was retained for further phase II studies. Of the 25 patients assessable for response, five achieved partial responses with a response rate of 20% (95% CI, 7 to 41%). The median survival time was 7 months and the 1-year survival rate was 24% (95% CI, 9 to 45%). CONCLUSION: The combination of carboplatin given on day 1 and gemcitabine given on days 1 and 8 every 3 weeks seems to be an acceptable regimen. The DLT consists exclusively of severe thrombocytopenia. Despite the MTD was not reached with carboplatin AUC 6 mg/ml per min and gemcitabine 1500 mg/m(2), the recommended dose for further phase II studies is carboplatin AUC 6 mg/ml per min and gemcitabine 1250 mg/m(2).

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.

Dose optimization of gallium chloride, orally administered, in combination with platinum compounds.

An individual dose adaptation for cisplatin (CDDP), etoposide and gallium chloride (GaCl3) was proposed to improve the efficacy of this combination chemotherapy and avoid its toxicity. A clinical study was performed in 28 non small cell lung cancer patients, to verify this hypothesis. CDDP and etoposide were administered as continuous infusions every 3 weeks and GaCl3 orally during and between the CDDP-etoposide sequential infusions. CDDP doses were adjusted to achieve, during each 5 day infusion, an area under the total plasma platinum concentrations versus time curve (AUC Pt 0-120) ranging between 80,000 and 100,000 micrograms/l.h. Etoposide dosages were 120 mg/24 h during days 1-3 of the CDDP infusion. GaCl3 dosages were adjusted to obtain plasma gallium (Ga) concentrations ranging between 200 and 400 micrograms/l. The proposed methods of adaptation were successful from a pharmacokinetic point of view as AUC Pt 0-120 were respectively 81351 +/- 4788, 88268 +/- 8451 and 88331 +/- 8778 micrograms/l.h during the first 3 courses, and plasma Ga concentrations, determined during the 2nd and 3rd CDDP courses, 16 hours after the beginning of the CDDP infusion, were respectively 264 +/- 127 and 313 +/- 186 micrograms/l. However, these results were not pharmacodynamically successful and the therapeutic window was not confirmed. Past clinical trials with GaCl3 will be reviewed, as well as the factors which modify the pharmacokinetics or the pharmacodynamic effects of CDDP and GaCl3. From this review, an optimal dosage of 400 mg GaCl3 could be proposed to potentiate a combination chemotherapy with a platinum compound. The target AUC of the platinum compound should be the AUC avoiding its cumulative toxicity.

Bilateral bronchioloalveolar lung carcinoma: is there a place for palliative pneumonectomy?

OBJECTIVE: Bronchioloalveolar lung carcinoma (BAC) is characterized by bronchial and lymphatic dissemination explaining multifocal and bilateral spreading. Bilateral BAC is usually considered as a contraindication to surgery. Regarding poor efficacy of symptomatic and oncological treatments, we hypothesized that surgery might play a role to palliate hypoxemia associated with serious intrapulmonary shunting, as well as continuous bronchorrhea. METHODS: We retrospectively studied here four consecutive patients, who underwent palliative pneumonectomy. RESULTS: The shunt was confirmed again at the time of the surgery by a pulmonary artery occlusion demonstrating immediate improvement in arterial oxygen saturation from 89% at baseline to 98% after occlusion. Lung resections consisted of a left pneumonectomy in three cases and a right pneumonectomy in one. PaO(2) levels under 5l/min oxygen therapy improved dramatically when comparing preoperative data (mean 50.5 mmHg) to post-operative results (mean 150 mmHg). One patient died postoperatively. Three patients, who experienced an uneventful immediate post-operative course, received chemotherapy after surgery. Improvement of quality of life is testified by the absence of both symptoms and any need for oxygen therapy for few months. Disabling symptoms reappeared at 1, 8 and 10 months. Survival of these patients was 3, 12 and 18 months. CONCLUSIONS: These results support the interest of consideration of a surgical resection for highly selected patients presenting with bilateral BAC and severe intrapulmonary shunting.

Pirarubicin phase II study in untreated metastatic small-cell lung carcinoma. A cooperative study of the Groupe Français de Pneumo-Cancérologie (GFPC).

Pirarubicin (THP) (Roger Bellon Laboratory, France) is a new anthracycline under clinical development. In order to assess the efficacy and toxicity of the drug in small-cell lung carcinoma (SCLC), we have undertaken this trial in front-line therapy in patients with metastatic disease, PS less than 3 and at least one evaluable lesion. Responses were assessed after two cycles of THP (60 mg/m2 i.v. bolus every 3-4 weeks) and a further cross over to VP16 + CDDP (three cycles) was systematic whatever the response to THP. This crossover was performed after only one cycle in case of obvious progression. From June 1988 to April 1990, 32 patients were enrolled: 6 were ineligible (4 non-SCLC, 2 M0), 26 patients were fully evaluable for THP and 18 patients for VP16-CDDP. The characteristics of the patients were as follows: mean age 57.4 years (38-71); T4: 54%; T3: 27%; T2: 19%; N3: 62%; N2: 35%; No: 4%. The efficacy was as follows 1 complete response and 2 partial responses (confirmed by endoscopy); 12 patients received only one cycle because of obvious progression; the overall response rate is 12% (95% confidence interval 0-24%). The patient who had complete response after pirarubicin remained in CR after VP16-CDDP, whereas the 2 patients who had partial response achieved CR for one and PR for the other; among the 15 who did not respond 1 CR and 7 PR were observed. The only significant toxicity of THP was granulopenia without infection. THP seems to be an effective anthracycline in SCLC, and the study is continuing. A response could be reached in 50% of the nonresponders with standard therapy and 10 of 24 patients (42%) finally responded. Therefore, this schedule for testing new drugs in metastatic SCLC appears ethically acceptable.

Lenograstim as support for ACE chemotherapy of small-cell lung cancer: a phase III, multicenter, randomized study.

This phase III study was conducted to evaluate the usefulness of lenograstim as support for ACE (doxorubicin, cyclophosphamide, and etoposide) chemotherapy in previously untreated patients with small-cell lung cancer. Patients were randomized to receive up to six 3-week cycles of either ACE alone (n = 139) or ACE with lenograstim support (150 microg/m2/day subcutaneously, days 4-13, n = 141). Compared with the chemotherapy-alone group, the lenograstim support group was more likely to achieve neutrophil recovery (absolute neutrophil count, > or =1.5 x 10(9) cells/l) by day 14 (95.8-100% vs. 14.3-24.1% across the cycles) and less likely to experience at least one infectious episode (36.7 vs. 54.0%; p = 0.004), chemotherapy delay (51.8 vs. 56.2%; NS), or dose reduction (17.3 vs. 27.7%; p = 0.037). Objective response and event-free and overall survival rates were similar. Lenograstim was well tolerated. Lenograstim may allow the interval between cycles of ACE to be reduced to 2 weeks; such dose intensification may lead to more favorable objective response and survival rates.

[Serum and cerebrospinal fluid levels after high dose of etoposide administrated intravenously]. / Taux sériques et taux dans le liquide céphalo-rachidien après forte dose d'étoposide administrée par voie intraveineuse.

Seric values have been evaluated in 24 patients receiving high doses of etoposide. In 6 patients, CNS value was evaluated simultaneously. After 2 perfusions with 250 mg/m2 at 12 h interval, seric value is 35.3 micrograms/ml + 10.3, the value after 6 perfusions is 31.1 micrograms/ml + 6.5. The variation of CNS value observed from 0.08 to 0.49 micrograms/ml is 0.36 to 1.29% of the seric value; there is no positive correlation with seric value. Only one patient out of 6 has a partial response of CNS metastases.

[Prognostic value of pre-therapeutic levels of carcino-embryonic antigen in primary bronchial carcinoma]. / Valeur pronostique du taux préthérapeutique de l'antigene carcinoembryonnaire dans les cancers bronchiques primitifs.

To evaluate the pronostic value of an elevated seric carcinoembryonic antigen (CEA > 10 ng/ml) at diagnosis, in patients with lung cancer, a pair study was done: couples of patients with same staging and histologic type were established, one patient with high CEA level compared to one patient with normal CEA level (< 5.5 ng/ml). Other markers were measured: neuron specific enolase (NSE), squamous cell carcinoma (SCC) or Cyfra 21-1. Survival was the end point of comparison. For 89 couples created, patients with low CEA level had a better survival rate at one year ( p = 0.02), this prognosis advantage was confirmed by a comparison of survival curves with Mantel-Cox and Breslow test (p = 0.01), but not by the signs test. These differences were also observed for the 71 couples of squamous cell carcinomas and adenocarcinomas, and the apparied signs test was still not significant. The poor prognosis persisted for patients with high CEA level, when one another marker's level (NSE or SCC or Cyfra 21-1) was increased, in comparison with patients with any marker increased. On 29 couples of all histological subtypes or on the 25 couples of non small cell lung cancer, the signs test and the comparison of survival curves were significant, but not the 1 year survival rate. This study shows that a CEA level greater than 10 ng/ml at diagnosis is a poor pronostic factor in patients with lung carcinoma, independent of the stage of disease and of the histologic type.

[Detection of human papillomavirus by polymerase chain reaction in primary lung carcinoma]. / Détection de papillomavirus humain par amplification génique dans les cancers bronchiques primitifs.

Human papillomaviruses (HPV) have been implicated in the pathogenesis of human squamous cell carcinoma, specially of cervical carcinomas. In previous studies concerning primary lung cancer, DNA of HPV subtypes was detected by in situ hybridization or polymerase chain reaction (PCR), up to 30% of the cases, namely in squamous cell carcinomas. A series of 31 frozen biopsies of lung carcinomas (surgical biopsies or through fiber optic bronchoscopy) were examined for the presence of HPV DNA by nested PCR. Primers for the two steps were type-specific primers (6/11-16 and 18; kit Amplicis-HPV) for the transforming region of HPV. HPV-DNA was found in five tumors: in two of 18 cases of squamous cell carcinoma (11%), in one of four cases of adenocarcinoma, in one of six cases of small cell carcinomas and in the unic case of neuro-endocrin carcinoma. No case of the two large cell undifferentiated carcinomas was positive. There were three cases of HPV 6/11, one case of HPV 16, and one sample positive for HPV 6/11 and HPV 18. No morphologic changes consistent with HPV lesions were observed. The frequency of 11% among the squamous cell carcinomas is near those found by previous studies (9 to 20% for HPV 6-11-16-18). For the first time, HPVs have been detected in neuro-endocrin tumors, and this have to be confirmed by studies of many more cases. So HPV might play a role as promoter in carcinogenesis of any types of lung carcinoma, although at a low frequency.

[Chemotherapy with high-dose cisplatin in brain metastasis of lung cancers]. / Chimiothérapie par cisplatine à forte dose dans les métastases cérébrales des cancers du poumon.

CDDP is one of the most active single drugs in non small cell lung carcinoma. High doses of 200 mg/m2 are well tolerated when fractionated doses are used over a period of 5 d. Twenty-four consecutive patients (male, age range 38-70 y) with brain metastasis of lung carcinoma were included in this study. The total dose of CDDP - 200 mg/m2 - was divided into 5 equal daily fractions, infused over 6 h. Parenteral hydratation commenced the night before therapy. Efficiency was assessed by means of CT scan 15-30 d after the last course of chemotherapy. Complete response was achieved if no lesion was found on the CT scan; partial deafness 2 cases, renal toxicity 1 case, severe myelotoxicity 2 cases. Efficiency: failure was observed in 17 cases, objective responses in 7 cases (2 cases without injection contrast in the tumor, 3 partial regressions, 2 complete regressions). Thirty per cent of patients in this study exhibited an objective response with low toxicity. CDDP seems to be very useful in cerebral metastasis of lung carcinoma.

[Carboplatin-VP16 combination in non small cell lung cancers in the aged patient. A study of the French group in pneumology (GFPC)]. / Association carboplatine-VP16 per os dans les cancers bronchiques non à petites cellules du sujet âgé. Etude du groupe français de pneumocancérologie (GFPC).

UNLABELLED: Between February 1992 and May 1993, 22 patients older than 75 years, with non small cell lung cancer, were treated with carboplatin and oral etoposide. There were 18 men and four women with a median age of 79 years. Fourteen patients had an epidermoid carcinoma: four had an adenocarcinoma and four had an undifferentiated carcinoma. Carboplatin was administered intravenously on day 1 at a dose of 300 mg/m2; oral etoposide was administered at a dose of 600 mg/m2 (two capsules daily) for 9, 10, 11, or 12 days according to body surface. Courses were repeated every 28 days for a total of three courses. TOXICITY: 15 patients (68%) had received previous chemotherapy. Myelosuppression was the main problem with one grade IV and five grade III hematologic toxicities. We observed one mild neurologic toxicity. RESULTS: 19 patients were evaluable for response. We observed one complete response (5%), five disease stabilizations (26%) and 13 disease progressions. Median survival was 5 months. These results led to discontinue this study.

[High-dose ifosfamide in patients with stage IV non-small cell lung cancer: phase II trial from the Groupe français de pneumo-cancérologie (GFPC)]. / Ifosfamide à forte dose chez des patients porteurs de cancers bronchiques non à petites cellules de stade IV: essai de phase II du 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.
