Prognostic factors for patients with small cell lung carcinoma: analysis of a series of 763 patients included in 4 consecutive prospective trials with a minimum follow-up of 5 years.

BACKGROUND: The purposes of this study were to identify prognostic factors for response to chemotherapy, overall survival, and long term survival of patients with small cell lung carcinoma and to construct a classification of patients on the basis of their expected overall survival. METHODS: In the 763 patients registered in 4 consecutive clinical trials conducted by the European Lung Cancer Working Party from 1982 to 1993, the impact of 21 pretreatment variables assessable in a routine practice was analyzed for the various outcomes with a minimum follow-up of 5 years. RESULTS: The key prognostic role of disease extent was confirmed for all the outcomes. Additional independent prognostic factors for response to chemotherapy were gender, neutrophil count, and hemoglobin level; for overall survival, these factors were Karnofsky performance status, gender, and neutrophil count. Recursive partitioning and amalgamation algorithms (RECPAM) analysis classified patients into 4 groups, taking into consideration disease extent, Karnofsky performance status, age, gender, and neutrophil count. Median survival times for the 4 groups were 60, 47, 36, and 28 weeks, respectively. For long term survival, defined as a minimum survival of 2 years (9% of the patients), Karnofsky performance status was the only independent predictive factor, along with the achievement of a complete response (if this was taken into consideration). Small cell lung carcinoma remained the main cause of death among these patients. Cure was infrequent, with only 14 patients alive and disease free at 5 years (1.8%). CONCLUSIONS: In this study the long term prognosis associated with small cell lung carcinoma was poor. The well-known prognostic values of disease extent and Karnofsky performance status were confirmed, but the authors also identified age and gender (which are more controversial) as independent characteristics, in addition to citing the role of complete response in the attainment of long term survival. The independent role of neutrophils observed by the authors. must be validated by further studies.

A phase II trial testing gemcitabine as second-line chemotherapy for non small cell lung cancer. The European Lung Cancer Working Party. 101473.1044@compuserve.com.

The purpose of the present trial was to determine the activity of gemcitabine as a second-line chemotherapy for non small cell lung cancer (NSCLC). To be eligible, patients had to have pathologically proven NSCLC that has failed to respond to a first-line chemotherapy with a cisplatin-containing regimen, a Karnofsky performance status greater than 50 and adequate renal, haematological and hepatic functions. After registration, patients were treated by gemcitabine given i.v. at a dose of 1 g/m(2) on days 1, 8, 15 every 4 weeks. Response was assessed after two courses of therapy. Eighty-two patients have been registered, five are ineligible and 65 are assessable for response. Four partial responses were observed (6%). No change was documented in 18 cases (28%). Tolerance was good. A few grade III leucopenia and grade III-IV thrombopenia were observed. We conclude that gemcitabine has a modest activity as second-line chemotherapy for NSCLC. It has the advantage to be well tolerated and may thus be one drug to be proposed to the patients who have disease progression after a first-line chemotherapy and who ask for further treatment.

Empirical treatment of sepsis in neutropenic patients.

Febrile neutropenia remains a major cause of morbidity in cancer patients receiving chemotherapy. Although the mortality associated with febrile neutropenia has dramatically decreased over the last three decades, the overall death rate during and immediately after an episode of febrile neutropenia can be as high as 10% with half of the patients dying directly as a result of the infection itself. A series of developments has led to this marked reduction in mortality. Among them, a pivotal role has been played by the concept of hospital-based empirical therapy with broad-spectrum combinations of antibiotics, aimed primarily against Gram-negative organisms, namely Pseudomonas aeruginosa

Phase III randomized trial comparing moderate-dose cisplatin to combined cisplatin and carboplatin in addition to mitomycin and ifosfamide in patients with stage IV non-small-cell lung cancer.

A phase III randomized trial was conducted in patients with metastatic NSCLC, to determine if, in association with mitomycin (6 mg m(-2)) and ifosfamide (3 g m(-2)), the combination of moderate dosages of cisplatin (60 mg m(-2)) and carboplatin (200 mg m(-2)) - CarboMIP regimen - improved survival in comparison with cisplatin (50 mg m(-2)) alone - MIP regimen. A total of 305 patients with no prior chemotherapy were randomized, including 297 patients assessable for survival (147 in the MIP arm and 150 in the CarboMIP arm) and 268 patients assessable for response to chemotherapy. All but eight (with malignant pleural effusion) had stage IV disease. There was a 27% (95% CI, 19-34) objective response (OR) rate to MIP (25% of the eligible patients) and a 33% (95% CI, 24-41) OR rate to CarboMIP (29% of the eligible patients). This difference was not statistically significant (P = 0.34). Duration of response was not significantly different between both arms. There was also no difference (P = 0.67) in survival: median survival times were 28 weeks (95% Cl, 24-32) for MIP and 32 weeks (95% Cl, 26-35) for CarboMIP, with respectively 1-year survival rates of 24% and 23% and 2-year survival rates of 5% and 2%. The main toxicities consisted in emesis, alopecia, leucopenia and thrombocytopenia, that were, except alopecia, significantly more severe in the CarboMIP arm. Our trial failed to demonstrate a significant improvement in response or survival when patients with metastatic NSCLC were treated, in addition to ifosfamide and mitomycin, by combination of moderate dosages of cisplatin and carboplatin instead of moderate dosage of cisplatin alone. The results support the use of a moderate dose (50 mg m(-2)) of cisplatin in combination with ifosfamide and mitomycin for the chemotherapy of this disease.

The Multinational Association for Supportive Care in Cancer risk index: A multinational scoring system for identifying low-risk febrile neutropenic cancer patients.

PURPOSE: Febrile neutropenia remains a potentially life-threatening complication of anticancer chemotherapy, but some patients are at low risk for serious medical complications. The purpose of this study was to develop an internationally validated scoring system to identify these patients. MATERIALS AND METHODS: Febrile neutropenic cancer patients were observed in a prospective multinational study. Independent factors assessable at fever onset, predicting low risk of complications, on a randomly selected derivation set, were assigned integer weights to develop a risk-index score, which was subsequently tested on a validation set. RESULTS: On the derivation set (756 patients), predictive factors were a burden of illness indicating absence of symptoms or mild symptoms (weight, 5; odds ratio [OR], 8.21; 95% confidence interval [CI], 4.15 to 16.38) or moderate symptoms (weight, 3; OR, 3.70; 95% CI, 2.18 to 6.29); absence of hypotension (weight, 5; OR, 7.62; 95% CI, 2.91 to 19.89); absence of chronic obstructive pulmonary disease (weight, 4; OR, 5. 35; 95% CI, 1.86 to 15.46); presence of solid tumor or absence of previous fungal infection in patients with hematologic malignancies (weight, 4; OR, 5.07; 95% CI, 1.97 to 12.95); outpatient status (weight, 3; OR, 3.51; 95% CI, 2.02 to 6.04); absence of dehydration (weight, 3; OR, 3.81; 95% CI, 1.89 to 7.73); and age less than 60 years (weight, 2; OR, 2.45; 95% CI, 1.51 to 4.01). On the validation set, a Multinational Association for Supportive Care in Cancer risk-index score >/= 21 identified low-risk patients with a positive predictive value of 91%, specificity of 68%, and sensitivity of 71%. CONCLUSION: The risk index accurately identifies patients at low risk for complications and may be used to select patients for testing therapeutic strategies that may be more convenient or cost-effective.

A comparison of methods of calculation for estimating carboplatin AUC with a retrospective pharmacokinetic-pharmacodynamic analysis in patients with advanced non-small cell lung cancer. European Lung Cancer Working Party.

We retrospectively analysed the data obtained in a large randomised trial performed in 505 eligible patients with advanced non-small cell lung cancer. Its purpose had been to compare a combination of carboplatin (200 mg/m2) and cisplatin (60 mg/m2) with or without the addition of ifosfamide. The present retrospective analysis assessed two ways of dosing carboplatin: according to body surface area (mg/m2) or to the estimated targeted area under the concentration versus time curve (AUC). Two different methods were used in the latter calculation: the Calvert formula using the Cockroft approximation to evaluate the glomerular filtration rate and the Chatelut equation. There was an excellent linear correlation between them. With the Chatelut method, the calculated administered AUC were lower. Whichever method was used, carboplatin AUC was not significantly associated with antitumour response rate nor patient survival. A statistically significant increase in haematological toxicity, mainly thrombopenia, was observed with an increase in the AUC. This effect was observed whatever AUC variable was considered, i.e. total dosage at course one, total dosage during the first three chemotherapy courses or dose intensity during the first three courses. The effect remained highly significant after adjustment for treatment arm. We conclude that for a moderate carboplatin dose in non-small cell lung cancer, the therapeutic index could be improved if dosage is calculated according to the AUC.

A randomised phase III trial comparing consolidation treatment with further chemotherapy to chest irradiation in patients with initially unresectable locoregional non-small-cell lung cancer responding to induction chemotherapy. European Lung Cancer Working Party.

PURPOSE: A phase III randomised trial was conducted in patients with non-metastatic unresectable non-small-cell lung cancer in order to compare, in responders to induction chemotherapy, consolidation treatment by further chemotherapy to chest irradiation. PATIENTS AND METHODS: A total of 462 untreated NSCLC patients were eligible for three courses of induction chemotherapy (MIP) consisting of cisplatin (50 mg/m2), ifosfamide (3 g/m2) and mitomycin C (6 mg/m2). It was proposed that objective responders be randomised to either three further courses of MIP or to chest irradiation (60 Gy; 2 Gy per fraction given over six weeks). RESULTS: An objective response rate of 35% was achieved; 115 patients (including 52% with initial stage IIIA and 44% with initial stage IIIB) were randomised to consolidation treatment, 60 of them to further chemotherapy and 55 to chest radiotherapy. There was no significant difference in survival between the two arms, with a respective median and two-year survival of 42 weeks (95% confidence intervals (95% CI: 35-51) and 18% (95% CI: 8-28) for chemotherapy and 54 weeks (95% CI: 43-73) and 22% (95% CI: 11-33) for irradiation. There was also no statistical difference for response duration between the two arms but chest irradiation was associated with a significantly greater duration of local control than chemotherapy (median duration times: 158 vs. 31 weeks, P = 0.0007). CONCLUSIONS: For non-metastatic unresectable NSCLC treated by an induction chemotherapy regimen containing cisplatin and ifosfamide, if an objective response is obtained, consolidation treatments by further chemotherapy or by chest irradiation result in non-statistically different survival distributions, although a better local control duration is observed with radiotherapy.

Lung fibrosis induced by paclitaxel.

In a 59-year old man with IIIb non-small-cell lung cancer, a combined treatment with paclitaxel and carboplatin was used for potentiation of radiotherapy. The patient was alive and free of neoplastic disease 14 months after the end of treatment but irreversible lung fibrosis had developed.

The value of lung function measurements for the assessment of chemotherapy in lung cancer patients.

A retrospective analysis of lung function changes in lung cancer patients (NSCLC and SCLC) receiving various chemotherapy regimens, showed--statistically non significant--improvements of some parameters in responders, especially FEV1 and VC (mean increase of 230 and 310 ml after three cycles of chemotherapy), while stable values were observed in non responders. The majority of patients suffered from a decline in diffusing capacity, irrespective of response. Although the specificity and sensitivity of this functional evaluation are too low to allow lung function parameters to replace more conventional staging procedures, improvement in lung function in responders might indicate that chemotherapy can improve quality of life.

Evaluation of the TN sub-staging in patients with initially unresectable stage III non-small cell lung cancer treated by induction chemotherapy. The European Lung Cancer Working Party.

PURPOSE: This study attempted to investigate, in a cohort of patients with clinical stage III initially unresectable non-small cell lung cancer (NSCLC) treated by the same induction chemotherapy regimen, the prognostic value of clinical T and N sub-groupings in order to validate the current International Staging System (ISS). PATIENTS AND METHODS: All the eligible patients with stage III NSCLC (428 patients) registered in a clinical trial were included in the study investigating, after three courses of induction chemotherapy, the role, in responders, of chest irradiation in comparison to further chemotherapy. The chemotherapy regimen consisted of mitomycin C, ifosfamide and cisplatin. RESULTS: Patients with ISS 1986 stage IIIA had a significantly better survival than those with stage IIIB (median survival 47 vs 36 weeks; P = 0.01). A RECPAM analysis showed that patients with T1-T2 N3 and T4 N0-1-2 stage had a more similar prognosis to those with stage IIIA. That result leads to define two new sub-groups: stage IIIlalpha (T3-T4 N0-N1; any T N2; T1-T2 N3) and IIIbeta (T3-T4 N3), with a highly significant difference in survival between them (median survival: 45 vs 29 weeks; P < 0.0001). The superiority of that new classification on the ISS documented in our series of stage III patients for discriminating survival and tumour response has to be confirmed on another series in a multivariate context. CONCLUSION: For unresectable NSCLC treated by induction chemotherapy, stage III sub-classification by moving T4 N0-1 and T1-2 N3 tumours from stage IIIB to stage IIIA appeared to better correlate with prognosis. The usefulness of this new sub-division has to be tested in validation studies.

Imipenem versus targeted therapy in cancer patients.

In many instances, broad-spectrum antibiotics are initiated empirically in febrile cancer patients and continued for the whole duration of therapy. An alternative is to narrow the spectrum whenever the offending pathogen is identified. This study is aimed at comparing these two options. Non-neutropenic cancer patients with severe infections received empiric imipenem. After 72 h, those with microbiologically documented infection were randomized either to continue imipenem or to receive a targeted therapy. After 72 h of imipenem 76.1% were improved. After randomization, a higher efficacy was observed with imipenem (88.5 vs. 72.1%: P = 0.025). Bacterial and fungal superinfections were comparable. Costs were lower for targeted therapy in gram-positive infection and higher in gram-negative infection.

Science and pragmatism in the treatment and prevention of neutropenic infection.

The following aspects of the management of patients with granulocytopenia and fever are reviewed in this article: adaptation of initial antibiotic regimens to the recent changes in the most common causative pathogens (namely a change from Gram-negative bacteria to Gram-positive bacteria and fungi); subsequent modifications of the empirically administered treatments; improvement of the host's defence by reducing the duration of neutropenia; and indications for out patient therapy of febrile episodes.

Current attitudes for therapy of febrile neutropenia with consideration to cost-effectiveness.

Febrile neutropenia is a changing syndrome which requires periodic updates as our armamentarium against this condition improves, and the characteristics of the pathogens change. In addition, cost of therapy has become a major issue when designing therapeutic strategies. This article reviews the basis of the current therapeutic approaches to febrile neutropenia, and this information is used to propose an algorithm for the management of this condition taking into consideration, in addition to these medical aspects, cost-effectiveness.

Phase III randomized trial comparing cisplatin and carboplatin with or without ifosfamide in patients with advanced non-small-cell lung cancer. European Lung Cancer Working Party.

PURPOSE: A phase III randomized trial in patients with advanced non-small-cell lung cancer (NSCLC) was performed to determine if the addition of ifosfamide to moderate-dose cisplatin and carboplatin improved response rate (primary end point) and survival. PATIENTS AND METHODS: A total of 529 patients were randomized to receive a combination of moderate-dose carboplatin (200 mg/m2 intravenously [i.v.] on day 1) and cisplatin (30 mg/m2 i.v. on days 2 and 3) with (CCI arm) or without (CC arm) ifosfamide (1.5 g/m2 i.v. on days 1 to 3). There were 248 eligible patients on the CC arm and 257 on the CCI arm, with 220 and 238 patients assessable for response, respectively. All but 23 had stage IV disease with pleural effusion. RESULTS: There was a 16% objective response (OR) rate to CC and a 31% OR rate to CCI. That observed difference was highly statistically significant (P < 0.001). Duration of response and survival were not statistically different between arms. The CCI regimen was associated with significantly more acute toxicities: emesis, alopecia, leukopenia, and thrombocytopenia. The frequency of chronic renal, auditive, and peripheral neurologic toxicity was low in both arms (4.6% and 6.6%, respectively, after six courses of chemotherapy). The relative dose-intensity (RDI) of the CCI arm was significantly lower than that of the CC arm. CONCLUSION: The addition of ifosfamide to moderate-dose cisplatin and carboplatin significantly improves the antitumoral response rate, but has no apparent effect an survival in advanced NSCLC.

[The infectious complications of bronchial cancer].

Infection are part of the natural course of lung cancer but overall they are poorly understood. The clinical studies on which is based our knowledge often lack sufficient clinical and microbiological documentation of the infection. Nevertheless, infection is frequently caused by Gram+ pathogens, among which pneumococci remain common. When lung cancer patients are treated with chemotherapy, the resulting neutropenia predisposes further to infection; its spectrum is similar to what has been observed in other granulocytopenic patients. The frequency and severity of the infection depends mainly on the severity and duration of neutropenia. Cotrimoxazole prophylaxis in neutropenic patients with lung cancer has been found effective in several studies. As far as therapy of fever and/or infection in neutropenic lung cancer is concerned, it does not appear that it should be handled differently from febrile neutropenia in other chemotherapy treated neutropenic patients.

Treatment of neutropenic infection: trends towards monotherapy?

Febrile neutropenia has been a changing syndrome over the last 20 years. The perspectives and goals that we face today are mainly the constant adaptation of antibacterial prophylactic and therapeutic regimens to the emergence of resistant strains; the definition of prognostic factors influencing the outcome of febrile neutropenia; the introduction of pragmatic algorithms for adaptation of therapy; ambulatory and/or home therapy for certain categories of patients; the definition of indications for the use of cytokines to restore earlier bone marrow function and to help with home management of febrile neutropenia, and, finally, the recognition of risk factors for fungal infections and the improvement of our diagnostic as well as therapeutic anti-fungal strategies.
