Cisplatin versus cisplatin plus etoposide in the treatment of advanced non-small-cell lung cancer. Lung Cancer Working Party, Belgium.

We conducted a randomized study comparing the survival after treatment with cisplatin (120 mg/m2) or cisplatin plus etoposide (100 mg/m2 on days 1, 2, and 3) in 162 evaluable patients with advanced non-small-cell lung cancer (NSCLC). No statistically significant difference in survival was detected; the median survival was 26 and 22 weeks, respectively, for patients receiving cisplatin and for those receiving cisplatin plus etoposide. The objective response rate was 19% for cisplatin and 26% for the combination; the corresponding response rates were 17% and 43% in patients with limited disease. No significant differences were detected between the two study arms as far as toxicity was concerned, except for alopecia and granulocytopenia, which occurred more frequently in patients treated with cisplatin plus etoposide.

A randomized study comparing cisplatin or carboplatin with etoposide in patients with advanced non-small-cell lung cancer: European Organization for Research and Treatment of Cancer Protocol 07861.

The European Organization for Research and Treatment of Cancer (EORTC) Lung Cancer Working Party conducted a randomized trial comparing cisplatin (CDDP; 120 mg/m2, day 1) and carboplatin (CBDCA; 325 mg/m2, day 1) in combination with etoposide (VP16; 100 mg/m2, days 1, 2, and 3) in advanced non-small-cell lung cancer (NSCLC). Two hundred twenty-eight patients were eligible for survival and 202 assessable for response. We obtained 27 of 100 objective responses (ORs; 27%) in the CDDP arm and 16 of 102 (16%) in the CBDCA arm (P = .07). There was no significant difference in survival. Toxicity, consisting mainly of myelosuppression and renal function impairment, was significantly increased in the patients receiving the CDDP treatment. We conclude that CDDP plus VP16 was more active but also more toxic than CBDCA plus VP16 in advanced NSCLC.

Prognostic factors for survival in advanced non-small-cell lung cancer: univariate and multivariate analyses including recursive partitioning and amalgamation algorithms in 1,052 patients. The European Lung Cancer Working Party.

PURPOSE: This study attempted to determine the prognostic value for survival of various pretreatment characteristics in patients with nonresectable non-small-cell lung cancer in the context of more than 10 years of experience of a European Cooperative Group. PATIENTS AND METHODS: We included in the analysis all eligible patients (N = 1,052) with advanced non-small-cell lung cancer registered onto one of seven trials conducted by the European Lung Cancer Working Party (ELCWP) during one decade. The patients were treated by chemotherapy regimens based on platinum derivatives. We prospectively collected 23 variables and analyzed them by univariate and multivariate methods. RESULTS: The global estimated median survival time was 29 weeks, with a 95% confidence interval of 27 to 30 weeks. After univariate analysis, we applied two multivariate statistical techniques. In a Cox regression model, the selected explanatory variables were disease extent, Karnofsky performance status, WBC and neutrophil counts, metastatic involvement of skin, serum calcium level, age, and sex. These results were confirmed by application of recursive partitioning and amalgamation algorithms (RECPAM), which led to classification of the patients into four homogeneous subgroups. CONCLUSION: We confirmed by our analysis the role of well-known independent prognostic factors for survival, but also identified the effect of the neutrophil count, rarely studied, with the use of two methods: a classical Cox regression model and a RECPAM analysis. The classification of patients into the four subgroups we obtained needs to be validated in other series.

A randomized study comparing a high and a standard dose of cisplatin in combination with etoposide in the treatment of advanced non-small-cell lung carcinoma.

We conducted a randomized trial comparing a high (120 mg/m2 day 1) v a standard (60 mg/m2 day 1) dose of cisplatin in combination with etoposide (120 mg/m2 days 3, 5, and 7) in advanced non-small-cell lung carcinoma (NSCLC). Two hundred forty-one patients were evaluable for survival and 207 for response. We obtained a 25% objective response rate in the standard-dose arm and 29% in the high-dose arm; this difference was not statistically significant. There was no significant improvement in the overall survival or survival of responders with the high-dose regimen. However, toxicity (mainly myelosuppression) was significantly increased in the patients receiving the higher dose of cisplatin. An analysis of prognostic factors showed that disease progression, loss of body weight, performance status, and prior therapy were predictive parameters of survival.

Multiple-drug weekly chemotherapy versus standard combination regimen in small-cell lung cancer: a phase III randomized study conducted by the European Lung Cancer Working Party.

PURPOSE: A randomized trial was conducted in patients with small-cell lung cancer (SCLC) to determine if survival can be improved by a weekly chemotherapy regimen combining various drugs. PATIENTS AND METHODS: Two hundred twenty-three patients were randomized to receive either six courses of a multiple-drug combination (MDC) regimen (Adriamycin [ADR; doxorubicin; Farmitalia Carlo Erba, Milan, Italy] 25 mg/m2 intravenously [i.v.] on day 1; etoposide [VP16] 120 mg/m2 i.v. on day 1; cyclophosphamide [CPA] 500 mg/m2 i.v. on day 1; cisplatin 60 mg/m2 i.v. on day 8; vindesine [VDS] 3 mg/m2 i.v. on day 8; vincristine [VCR] 2 mg i.v. on day 15; methotrexate [MTX] 100 mg/m2 i.v. on day 15), or a standard chemotherapy (SC) regimen (ADR 50 mg/m2 i.v. on day 1; CPA 1 g/m2 i.v. on day 1; VP16 80 mg/m2 i.v. on days 1 to 3). RESULTS: In 98 MDC-treated and 101 SC-treated assessable patients, we observed 69% and 62% objective responses rates, respectively. There was no significant difference in survival, with median durations and 2-year overall survival rates of 49 and 43 weeks and 8.5% and 7.9%, respectively. There was a significant increase in response rate in favor of MDC patients with limited disease (84% v 62%). Toxicity was tolerable, although SC was more hematotoxic, with 76% (v 59%) experiencing leukopenia and 17% (v 7%) experiencing thrombocytopenia (grades III and IV). If the cumulative doses received were nearly equal to the scheduled cumulative doses in both arms, the total relative dose-intensity (RDI) was significantly higher in the SC arm. The difference was due to increased treatment delays in the MDC arm. CONCLUSION: Weekly MDC failed to improve survival rates in patients with SCLC.

Long-term survival after chemotherapy containing platinum derivatives in patients with advanced unresectable non-small cell lung cancer. European Lung Cancer Working Party.

The study set out to determine the rate of long-term survivors (LTS) in patients treated with platinum-containing chemotherapy for advanced non-small cell lung cancer (NSCLC), to identify prognostic factors predicting long-term survival (> or = 2 years) and to report the LTS natural history. Eligible patients with advanced NSCLC treated by chemotherapy in one of seven trials conducted by the European Lung Cancer Working Party from December 1980 to August 1991 were included. All patients received cisplatin and/or carboplatin. Of these, 1052 patients were eligible and 24 variables were analysed as potential prognostic factors. Actuarial 2-year and 5-year survival rates were, respectively, 7.4 and 1.8%. All patients surviving for > or = 5 years had limited disease and were treated by complementary chest irradiation and/or surgery. Univariate prognostic factor analysis for LTS identified as significant no major weight loss, limited disease, no liver metastases, normal white blood cells and neutrophils and normal lactic dehydrogenase levels. By multivariate analysis, the only significant factor was limited disease. Objective response to chemotherapy was also found to be, as disease extent, a highly significant predictor for LTS. Thus, the two best prognostic factors for LTS were non-metastatic disease and response to chemotherapy.

Response to chemotherapy has predictive value for further survival of patients with advanced non-small cell lung cancer: 10 years experience of the European Lung Cancer Working Party.

The aim of this study was the assessment of the predictive value for survival of an antitumoral response to three courses of chemotherapy in association with various pretreatment characteristics in patients with non-resectable non-small cell lung cancer treated by cisplatin- (or carboplatin)-based combination regimens. Patients considered for this study were eligible patients with advanced non-small cell lung cancer registered in one of the seven trials conducted by the European Lung Cancer Working Party from December 1980 to August 1991. All these trials tested chemotherapy regimens with platinum derivatives (cisplatin and/or carboplatin). In this population of 1052 eligible patients, 752 were assessed in this analysis. Data were prospectively collected on 23 pretherapeutic variables and objective response after three chemotherapy cycles. The predictive value of response to chemotherapy on survival (measured from the time of response assessment i.e. 12 weeks after registration in the trial) was studied by univariate analysis as well as by multivariate methods (adjustment of the impact of several covariates simultaneously on the dependent variable) with adjustment for the pretreatment prognostic variables. After three cycles of chemotherapy, the global estimated median survival time was 24 weeks with a 95% confidence interval of 22-25 weeks. By univariate analysis, we identified an objective response to chemotherapy as a highly significant discriminant marker (P < 0.0001) for further survival with estimated median survival times of 41 weeks (95% CI: 38-46) and 19 weeks (95% CI: 17-20), respectively, for the responding and non-responding patients. In a Cox regression model fitted to the data using a forward stepwise procedure, this variable was the first selected explanatory variable. Its effect was adjusted by the introduction in the model of initial disease extent, Karnofsky performance status, serum calcium level and white blood cell count. These results were consistent with those obtained by application of recursive partitioning and amalgamation algorithms (RECPAM) which led to a classification of the patients into three homogeneous subgroups. Our results, using a classical Cox regression model consistent with those highlighted by application of a RECPAM analysis, found an objective response to chemotherapy to be a predominant predictive factor for further survival, although it did not allow any conclusion about a causal relationship. The RECPAM results led to a classification of the patients into three subgroups which needs to be validated in other series.

A randomized trial of two platinum combinations in patients with advanced non-small cell lung cancer: a preliminary report. European Organization for the Research and Treatment of Cancer--Lung Cancer Working Party.

A randomized study with cisplatin (120 mg/m2) or carboplatin (325 mg/m2) plus etoposide (100 mg/m2, days 1 to 3) in 162 evaluable patients with advanced non-small cell lung cancer (NSCLC) compared response and survival after treatment. No statistically significant difference in survival rates was detected; median survival was 25 weeks for patients receiving cisplatin and 24 weeks for those receiving carboplatin. The objective response rate was 25% for cisplatin plus etoposide and 20% for carboplatin plus etoposide. Granulocytopenia, diarrhea, and nephrotoxicity were significantly more frequent with cisplatin plus etoposide than with carboplatin plus etoposide. Severe nausea and/or vomiting occurred during 59 of 77 courses (77%) with cisplatin and 48 of 75 (64%) with carboplatin (P = .13). Unlike cisplatin plus etoposide, carboplatin plus etoposide was administered on an outpatient basis. At the dose used in the present study, carboplatin plus etoposide was as effective as but less toxic than cisplatin plus etoposide for NSCLC and could be given more easily.

A four-drug combination chemotherapy with cisplatin, mitomycin, vindesine and 5 fluorouracile: a regimen associated with major toxicity in patients with advanced non-small cell lung cancer.

The purpose of this study was to determine the activity of a 4-drug combination chemotherapy: cisplatin, mitomycin C, vindesine and 5-fluorouracil (5-FU) in patients with advanced non-small cell lung cancer (NSCLC). Chemotherapy consisted of the administration of cisplatin (30 mg/m2 d 1-4), mitomycin C (10 mg/m2 d 1), vindesine (3 mg/m2 d 1) and 5-FU (1 g/m2 d 1-4 by continuous intravenous infusion). In patients older than 70 years, and in those who received prior irradiation or chemotherapy, cisplatin and 5-FU were omitted on day 4. Courses were repeated every 4 weeks and evaluation of response was performed after the first 2 courses. In case of response, treatment was continued until best response or untolerable toxicity. Among 182 eligible patients, 75% had received no prior therapy; 41% had locoregional disease and 59% metastatic disease; 41% lost more than 5% of their pretherapy body weight. A 34% objective response rate was observed in the 164 evaluable patients (31% in all the eligible patients) including 4 complete and 52 partial responses. Patients with locoregional disease had a significantly better response rate than those with metastases (44% vs 27%). The overall median survival was 26 weeks. Significant hematological toxicity was documented but the most serious adverse event was the occurrence of 18 (10%) cardiac or sudden deaths. These toxic deaths were significantly associated with a 5% loss of body weight prior to therapy. The addition of 5-FU to combination of cisplatin, mitomycin C and vindesine does not improve antitumoral effect but results in very significant cardiac toxicity.

[Small cell bronchial cancer. Comparison of results of weekly polychemotherapy using multiple drugs with standard chemotherapy. European Lung Cancer Working Party]. / Cancer bronchique à petites cellules. Comparaison des résultats d'une polychimiothérapie hebdomadaire avec de multiples médicaments avec une chimiothérapie standard. European Lung Cancer Working Party.

The administration of multiple cytostatic drugs on a weekly basis has been proposed as a new intensive chemotherapy modality for small-cell lung cancer. The European Lung Cancer Working Party has conducted a randomized trial comparing to a standard regimen (cyclophosphamide + adriamycin + etoposide given at the cycle beginning) a weekly chemotherapy with 7 active drugs (cyclophosphamide + adriamycin + etoposide on day 1; cisplatin + vindesine on day 8; methotrexate + vincristine on day 15). A total of 215 eligible patients have been registered. There has been no significant difference between the 2 arms for response and for survival. The total relative dose-intensity has been lower in the weekly chemotherapy arm. This approach has failed to improve current results.

[Prognostic factors in advanced stage non-small cell bronchial cancer: experiences of the European Lung Cancer Working Party]. / Facteurs pronostiques des cancers bronchiques non à petites cellules au stade avancé: expérience de l'European Lung Cancer Working Party.

The European Lung Cancer Working Party has investigated prognostic factors for response, overall survival, long term survival in a population with advanced non small cell lung cancer registered in a clinical trial evaluating platinum derivatives-containing chemotherapy regimens. Various factors have been identified in multivariate analyses and were classified using RECPAM methodology. In addition to the clinical factors such as disease extent and performance status were shown, as significant predictors, rarely studied biological factors like pretherapeutic leucocyte and polynuclear levels. The obtention of an objective response to chemotherapy appeared to be a major prognostic factor for further survival.

[Pneumococcal spondylodiscitis. A case report]. / Spondylodiscite à pneumocoque. A propos d'un cas.

We report on a case of a 66 years-old patient suffering weight loss and lumbar pain, localized at L2-L3. A spondylodiscitis was revealed by CT and MRI; intervertebral disc puncture was positive for Pneumococcus Pneumoniae. The clinical evolution was good with the anti-bacterial treatment, while the patient developed a synostosis L2-L3. Incidence, bacteriology, imaging and therapy of spondylodicitis are discussed.

Phase II study of an intensive combination chemotherapy with cisplatin, adriamycin, etoposide and cyclophosphamide (CAVE) in small cell lung cancer.

One hundred and twelve patients with small cell lung cancer (SCLC) were treated with a combination (CAVE) of cisplatin (60 mg/m2 day 1), adriamycin (45 mg/m2 day 1), etoposide (80 mg/m2 days 1-2-3) and cyclophosphamide (1 g/m2 day 1) given every 4 weeks. A total of 10 courses were given. Response evaluation was initially evaluated after the first two courses of CAVE and repeated at least after treatment completion. This regimen was associated with severe hematological toxicity, mainly leucopenia; five toxic deaths related to sepsis were observed. One hundred and one patients were evaluable for response: 63 with limited disease and 49 with extensive disease. Overall complete and partial response rates after the first two courses of chemotherapy were 16% and 63% respectively but 14 late complete responses were documented, leading to a 30% total complete response rate; 38% in patients with limited disease and 19% in those with disseminated disease. Median overall survival was 46 weeks with a 17% 2 year survival. The only significant prognostic factor for survival was the type of response. There was no survival difference between 'early' and 'late' complete responders. Complete responders had a 75 week median survival time with a 34% 2 year survival. CAVE is thus an effective regimen for SCLC, but with a considerable toxicity.

Evaluation of squamous cell carcinoma antigen as a new marker for lung cancer.

Carcinoembryonic antigen (CEA) is the only tumor marker of proven, although limited, value for the management of patients with non-small cell lung cancer (NSCLC). The authors have prospectively assessed the potential value of a new tumor marker, squamous cell carcinoma antigen (SCC Ag), in a large series of patients with advanced lung cancer (LC). Squamous cell carcinoma antigen and CEA levels were measured in 382 healthy persons (N1 group), 90 patients with benign pulmonary diseases, and 291 patients with LC (129 with SCLC and 162 with NSCLC, including 96 with squamous LC). Carcinoembryonic antigen levels were higher in smokers than in nonsmokers, but smoking habits did not influence the serum concentrations of SCC Ag. Elevated values (above the 95th percentiles of N1, i.e., 7.5 ng/ml for CEA and 3.0 ng/ml for SCC Ag) were observed in 11.1% of patients with benign pulmonary diseases for both markers. Carcinoembryonic antigen was more sensitive than SCC Ag, even for squamous LC (56% versus 35% of elevated values, P less than 0.01). The specificity toward squamous LC was better, however, for SCC Ag, for which levels were elevated in only 8.5% of SCLC and in 18% of other forms of NSCLC, compared with 49% and 55%, respectively, for CEA. Moreover, measurement of SCC Ag and CEA levels did not give redundant information: thus, in squamous LC and SCC Ag level was elevated in 32% of the patients with a normal CEA level, increasing from 57% to 71% the proportion of patients with at least one elevated marker. Lastly, elevation of CEA or SCC Ag levels was an adverse prognostic factor in squamous LC (P = 0.05 for CEA; P = 0.07 for SCC Ag). In conclusion, SCC Ag appears to be worthwhile of further investigation in squamous LC. The authors found that this new marker provided additional information on CEA and that it was more specific for squamous LC than CEA.

Combination chemotherapy with mitomycin and vindesine in advanced non-small cell lung cancer: a pilot study by the Lung Cancer Working Party (Belgium).

The combination of mitomycin plus vindesine in advanced non-small cell lung cancer induced an objective response rate of 23% in 43 evaluable patients: 33% in nonpretreated patients (nine responses among 27 patients) and 6% in pretreated patients (one response among 16 patients). Toxicity was tolerable. We conclude that the regimen was a moderately active and easy to administer treatment for advanced non-small cell lung cancer.
