[COVID-19 and medical publications: How three articles have influenced the media and public decisions in France]

Cet article détaille le processus et les aléas de publication de trois articles se rapportant au SARS-CoV-2 et à la maladie qu’il provoque (COVID-19). Ces trois articles ont été publiés à un mois d’intervalle, entre mars et mai 2020. Leur médiatisation a conduit les autorités de santé françaises à intervenir. Notre article ne s’intéresse pas et n’évalue pas la qualité scientifique des articles présentés, mais a pour unique objectif d’ouvrir la réflexion sur la publication médicale. En décrivant ces trois cas particuliers, il soulève des questions sur la rétractation des articles, l’évaluation par les pairs, la prépublication, la paternité des articles, et la diffusion des informations scientifiques médicales y compris via les médias de masse. Il discute des nouveaux modes d’édition qui se profilent et de la diffusion des informations publiées en recherche clinique.

Five-year survival and prognostic factors according to histology in 6101 non-small-cell lung cancer patients

OBJECTIVE

To estimate five-year survival in non-small-cell lung cancer (NSCLC) patients according to histology and to identify independent prognostic factors by histology.

METHODS

Data were obtained during the KBP-2010-CPHG study, which included all new cases of primary lung cancer diagnosed in 2010 in 104 non-academic hospitals.

RESULTS

In all, 3199 patients had adenocarcinoma (ADC), 1852 squamous cell carcinoma (SCC), 754 large cell carcinoma (LCC). Five-year survival was 13.3% [12.1%-14.5%] for ADC, 14.3% [12.7%-16.0%] for SCC, 9.6% [7.6%-11.9%] for LCC (P<0.001). Performance status, weight loss prior to diagnosis and tumour stage were consistently significant independent prognostic factors. Age (>70 years; P=0.004), male gender (P<0.001), and smoking (P<0.001) were independent negative prognostic factors for ADC. Epidermal Growth Factor Receptor (EGFR)-mutation tests, performed in 1638 ADC patients, were positive for 186. Five-year survival was 14.7% [10.3%-21%] and 10.9% [9.4%-12.6%] for mutated and wild-type EGFR, respectively (P<0.001). EFGR mutation was an independent positive prognostic factor (HR=0.5 [0.4-0.6], P<0.001); however, the proportional hazards assumption was not fulfilled and hazards were inverted after 35 months.

CONCLUSIONS

Five-year survival in patients managed in French non-academic hospitals for primary NSCLC in 2010 remained poor (<15%), whatever the histologic type. The independent negative prognostic factors for five-year survival were: weight, particularly weight loss prior to diagnosis; smoking (active or former) at diagnosis in ADC and LCC and smoking level at diagnosis in smoker patients with SCC. The independent positive prognostic factors were young age and female gender for ADC.

Metastatic NSCLC: Clinical, molecular, and therapeutic factors associated with long-term survival

BACKGROUND

Patients with metastatic non-small-cell lung cancer (NSCLC) who survive more than 2 years are considered long-term survivors (LTSs). The present study examined factors associated with long-term survival and collected information for future comparison.

METHODS

Clinical, molecular, and therapeutic data were collected from patients followed for primary stage IV (7th TNM classification) NSCLC within 2 years from diagnosis in the respiratory medicine departments of 53 French non-teaching hospitals. LTS and non-LTS records were compared. Factors associated with long-term survival were examined by univariate and multivariate analyses using logistic regression models.

RESULTS

Vital status at least 2 years after diagnosis was known for 1977 stage IV NSCLC patients; 220 (11.1%) were LTSs. On multivariate analysis, independent positive factors comprised: TTF-1(+) immunochemistry, EGFR-mutation, surgery, rescue radiotherapy, and targeted therapy. Independent negative factors comprised: prediagnosis weight loss>5kg, ECOG performance status>1, and primary radiotherapy.

CONCLUSIONS

Molecular biology and targeted therapy were decisive for long-term survival. With their development and their widespread implementation in clinical practice, the percentage of LTSs is expected to grow. Factors determining long-term survival found in this study should be taken into account when considering treatment options for patients with stage IV NSCLC.

[Second- or third-line treatment with erlotinib in EGFR wild-type non-small cell lung cancer: Real-life data]

INTRODUCTION

The benefit of tyrosine kinase inhibitors for patients with an EGFR wild-type non-small cell lung cancer (NSCLC) remains controversial.

METHODS

The survival of patients with an EGFR wild-type NSCLC who received second- or third-line erlotinib treatment was assessed using real-life data that had been collected in a prospective, national, multicenter, non-interventional cohort study.

RESULTS

Data from 274 patients were analysed, 185 (68%) treated with erlotinib and 89 (32%) treated with supportive care only. The median overall survival was 4.2months (95% CI [3.5; 5.4]) with erlotinib, and 1.3months (95% CI [1.0; 1.8]) with supportive care. Survival rate at 3, 6, and 12months was 62%, 37%, and 17%, respectively, with erlotinib, versus 20%, 8%, et 3%, with exclusive supportive care. Significant predictive factors for longer overall survival were the presence of adenocarcinoma, and use of 1st line chemotherapy including either taxanes, pemetrexed or vinorelbine (P<0.05).

CONCLUSION

Erlotinib remains a valuable therapeutic option to treat inoperable locally advanced or metastatic NSCLC after failure of at least one prior chemotherapy regimen in fragile patients who are not eligible for chemotherapy.

[Therapeutic strategies in patients undergoing surgery for non-small cell lung cancer. Results of the ESCAP-2011-CPHG study, promoted by the French College of General Hospital Respiratory Physicians (CPHG)]

BACKGROUND

The aim of ESCAP-2011-CPHG, promoted by the French College of General Hospital Respiratory Physicians, was to describe therapeutic strategies in lung cancer in the first 2 years after diagnosis, in a real-life setting. This article focuses on patients undergoing surgical management of a non-small cell lung cancer (NSCLC).

METHODS

A prospective multicentre study was conducted in 53 French general hospitals. For each patient with lung cancer diagnosed in 2010, a standardised form was completed following each change in treatment strategy up to 2 years after diagnosis.

RESULTS

Overall, 3418 of the 3943 included patients had NSCLC. 741 patients (21.7%) underwent curative surgery (stage 0-II, IIIA, IIIB, and IV: 65%, 27%, 3% and 5%, respectively). The therapeutic strategy changed less often in surgical than non-surgical patients and average follow-up time was longer: 23.3 months (SD: 9.3) versus 10.4 months (SD: 9.5) for non-surgical patients. Among patients with a surgical first strategy (92.6% of surgical patients as a whole), 56.9% did not receive any other treatment, 34.7% received chemotherapy, 5.9% radio-chemotherapy, 2.6% radiotherapy. At the end of follow-up, 55.8% were still alive without any other strategy, 13.1% had died, and 31.1% had received at least one more strategy. Among patients with a surgical second strategy, 63% had received chemotherapy alone during the first strategy.

CONCLUSIONS

ESCAP -2011- CPHG assessed everyday professional practice in the surgical management of NSCLC in general hospitals. It pointed out the discrepancies between current guidelines and the therapeutic strategies applied in real life conditions.

[One-year survival improvement in lung cancer in France. Results of the prospective real life studies KBP-2000-CPHG and KBP-2010-CPHG]

INTRODUCTION

The French college of general hospital respiratory physicians (CPHG) has conducted 10 years apart two prospective observational studies to assess changes in the primary lung cancer epidemiology and outcomes, including 1-year mortality.

METHODS

In 2000 and 2010, all volunteer adult patients followed in the respiratory department of general hospitals participating in the study were consecutively included if their lung cancer was histologically or cytologically diagnosed between 01 January and 31 December (sample date). Their vital status at least 1 year after inclusion and date of death (if applicable) were collected.

RESULTS

Respectively, 5667 and 7051 patients were included in the study in 2000 and 2010 and vital status of 5441 (96.0%) and 6981 (99%) patients known. One-year mortality rate was 61.8% in 2000 and 56.4% in 2010 (P<0.0001). Mortality rate significantly decreased from 2000 to 2010 in non-small-cell lung cancer (60.7% vs. 55.2%; P<0.0001) but not in small-cell lung cancer (66.9% vs. 64.2%; P=0.22). The year of diagnosis was an independent risk factor of mortality (OR=0.84; 95% CI: 0.77-0.91; P<0.0001).

CONCLUSION

Although it remains low (43.6% in 2010), life expectancy at 1 year for patients with lung cancer has improved in 10 years. Five-year results are expected to show whether this improvement is maintained or not over time.

[Ten-year evolution in non-small-cell lung cancer according to sex. Results of the KBP-2010-CPHG study by the College of General Hospital Respiratory Physicians]

INTRODUCTION

Comparison by sex and presenting features between 2000 and 2010 of the characteristics of new cases of non-small-cell lung cancer (NSCLC).

METHODS

Observational KBP-2010-CPHG study similar to KBP-2000-CPHG. Both studies were promoted by the French College of General Hospital Respiratory Physicians (CPHG). KBP-2010-CPHG collected data for 6083 NSCLC diagnosed between January 1st and December 31st, 2010, and followed in the respiratory departments of 119 French general hospitals.

RESULTS

In 2010, 24.4 % of the patients were women (16 % in 2000, p<0.0001). Compared to men, women were more commonly non-smokers (34.2 vs 4.7 %) or lighter consumers (37.2 vs 43.7 pack per years) (p<0.0001). Their tumours (mostly adenocarcinoma: 64.6 vs 48.7 %, p<0.0001) were more frequently diagnosed at stage IV (62.4 vs 56.9 %, p=0.0008). EGFR mutation research was more frequently performed (48.5 vs 31.0 %, p<0.0001) and positive (20.6 vs 5.2 %, p<0.0001) in women than men. Their treatment more frequently included targeted therapy (13.4 vs 5.7 %, p<0.0001). Compared to 2000, the percentage of non-smokers increased in men (4.7 vs 2.5 %, p<0.0001) while remaining stable in women (36.1 vs 34.2 %, p=0.32). The percentage of adenocarcinomas increased, particularly in men (48.7 vs 31.5 %, p<0.0001).

CONCLUSIONS

The percentage of women with NSCLC has increased in 10years in France. In 2010, the main gender differences persist, but have decreased with the increasing proportion of non-smokers and adenocarcinomas in men. Various hypotheses to explain these changes are discussed.

[Study KBP-2010-CPHG: inclusion of new cases of primary lung cancer diagnosed in general hospital pneumology departments between 1st January and 31 December 2010]

INTRODUCTION

The College of General Hospital Respiratory Physicians (CPHG) is following up the KBP-2000-CPHG study, performed ten years ago, with a new observational epidemiological study of primary lung cancer.

PATIENTS AND METHODS

The study includes all new cases of primary lung cancer diagnosed on histology or cytology between 1 January and 31 December 2010 and managed by one of the general hospital pneumology departments participating in the study. The primary objective is to estimate five-year mortality and to analyze risk factors. Secondary objectives are to describe the characteristics of this patient population and their management, and to estimate one, four and five-year survival rates. These data will be compared to those of the KBP-2000-CPHG study. The four-year prognosis score developed in 2000 will also be assessed in the new study. Data are collected by standardized questionnaire with exhaustiveness control.

EXPECTED RESULTS

One hundred and eight investigating centers have agreed to participate; 4000 to 5000 new cases of primary lung cancer should be collected and analyzed.

CONCLUSION

The study will describe the characteristics of patients presenting with primary lung cancer in the participating pneumology departments during the year 2010, and their diagnostic and therapeutic management, and assess changes over the last ten years.

[Five year survival for lung cancer patients managed in general hospitals]

INTRODUCTION

In 2000 the College of Pulmonologists of General Hospitals undertook an epidemiological study (KBP-2000-CPHG) enrolling all new cases of histologically confirmed lung cancer managed in general hospitals. This paper reports the five year survival in these cases.

METHODS

Vital status was available for 5447 out of 5667 patients included in the original study. The effect of different prognostic factors on mortality was assessed.

RESULTS

At 5 years 567 patients (10.4%) were still alive. Median survival for the 4880 (89.6%) deceased patients was 7 months. Univariate analysis identified age, smoking history, performance status, histological type and disease stage (TMN classification) as determinants of survival. For non-small cell lung cancer (n=4885) multivariate analysis identified five predictive factors for mortality - age, gender histological type, performance status and stage.

CONCLUSIONS

Five year survival in lung cancer continues to be poor. As the risk factors for poor outcome at the time of diagnosis are not modifiable and pending the results of screening studies reduction in mortality must rest on primary prevention.

Cancer bronchique du sujet âgé

INTRODUCTION

In France, the average age for the diagnosis of bronchial carcinoma is 64. It is 76 in the population of over 70. In fact, its incidence increases with age linked intrinsic risk of developing a cancer and with general ageing of the population. Diagnosis tools are the same for elderlies than for younger patients, and positive diagnosis mainly depends on fibreoptic bronchoscopy, complications of which being comparable to those observed in younger patients.

STATE OF THE ART

The assessment of dissemination has been modified in recent years by the availability of PET scanning which is increasingly becoming the examination of choice for preventing unnecessary surgical intervention, a fortiori in elderly subjects. Cerebral imaging by tomodensitometry and nuclear magnetic resonance should systematically be obtained before proposing chirurgical treatment. An assessment of the general state of health of the elderly subject is an essential step before the therapeutic decision is made. This depends on the concept of geriatric evaluation: Geriatric Multidimensional Assessment, and the Comprehensive Geriatric Assessment which concerns overall competence of the elderly.

PERSPECTIVES

This is a global approach that allows precise definition and ranking of the patient's problems and their impact on daily life and social environment. Certain geriatric variables (IADL, BADL, MMSE, IMC etc) may be predictive of survival rates after chemotherapy or the incidence of complications following thoracic surgery. The main therapeutic principles for the management of bronchial carcinoma are applicable to the elderly subject; long term survival without relapse after surgical resection is independent of age. Whether the oncological strategy is curative or palliative, the elderly patient with bronchial carcinoma should receive supportive treatments. They should be integrated into a palliative programme if such is the case. In fact, age alone is not a factor that should detract from optimal oncological management.

CONCLUSIONS

The development of an individual management programme for an elderly patient suffering from bronchial carcinoma should be based on the combination of oncological investigation and comprehensive geriatric assessment.

[Intestinal metastases from lung cancer]

INTRODUCTION

Intestinal metastasis from primary lung cancers is rare and usually asymptomatic.

CASE REPORT

We report two cases of symptomatic small bowel metastasis. The first one presented with a persistent anaemia occurring in a 54 year old man who had undergone a left lower lobectomy for a large cell carcinoma. The second case was a 75 year old man who presented with peritonitis which led to discovery of a lung primary.

CONCLUSION

Intestinal metastasis can be the presenting feature of, or complicate lung cancer. Symptomatology depends on metastasis localisation. Their treatment is difficult and they are associated with a poor prognosis.

Cohort KBP-2000-CPHG: Evaluation of prognosis factors for survival in primary bronchial cancer (PBC)

7204

Background: PBC has a guarded prognosis despite advances in treatment. The main epidemiologic changes observed during the last fifteen years are the strong progression in its incidence in women and the increase in adenocarcinomas. A prospective study of overall survival and survival according to sex and prognosis factors was set up from the cohort of study KBP-2000-CPHG. Methods: KBP-2000-CPHG is a prospective epidemiological study conducted throughout the year 2000 on histologically confirmed PBC patients treated in general hospitals. 5,667 patients were included. A survival study based on patient outcomes was launched between September 2004 and March 2005 in 137 centres. Each centre had to provide information on the vital status of its patients with, in the event of death, the date and cause. In the absence of vital status data, a graduated tracing strategy was set up including the interrogation of various files: city hall of the place of birth,etc. Results: 135 investigator centres out of the 137 initial centres took part. The 2 non-participating centres represented 56 patients. The vital status could be defined for 5441 of the other 5611 patients (97.0%). 88.4% of these patients had died (average time between inclusion and death: 10.5–10.7 months). In univariate study, survival status is linked with age (p < 0.0001), tobacco consumption (p < 0.0001), performance status (p < 0.0001), cancer type (small versus non small cell lung cancer-NSCLC: p < 0.0001) and for the NSCLC, with histological type (p < 0.0001) and TNM stage (p < 0.0001). According to multivariate analysis, survival status is related to age, performance status, cancer type and among the NSCLC, to age, sex, performance status, histological type and TNM stage. Conclusions: The survival study on PBC is the first one in France, including more than 5,400 patients. The first results show the prognosis role of age, sex, histological type, performance status and TNM stage.

CohorteKbp-2000-Cphg : évaluation des facteurs pronostiques de la survie du cancer bronchique primitif à 2 et 5 ans

INTRODUCTION

Lung cancer continues to have a poor prognosis despite some therapeutic advances.

BACKGROUND

The last fifteen years has seen a dramatic increase in the incidence of lung cancer in women and an increased proportion of adenocarcinomas in both sexes. A study of overall survival as a function of gender and other prognostic factors has been established using the cohort of patients from the study KBP-2000-CPHG.

METHODS

KBP-2000-CPHG is an epidemiological study carried out throughout the year 2000 looking at histologically confirmed primary lung cancers managed in general hospitals. 5,667 patients have been included. The study of survival looks at 2 and 5-year outcomes. The date and cause of death are recorded for each patient. In the absence of these data the date of the last contact is noted. If this is less than 4 months the patient is considered to be alive. If more than four months have elapsed a graduated strategy for establishing vital status is pursued which involves reviewing records from various different sources. RESULTS AWAITED: A preliminary review of the data was undertaken between September 2004 and March 2005 which obtained data on 5 567 patients. The analysis of survival according to sex and other forecast prognostic factors is underway.

[Treatment of anemia and bone metastasis in metastatic non-small-cell lung cancer. A French survey]

Use of erythropoietin (EPO) for chemotherapy-induced anemia and biphosphonates (BP) for bone metastasis has increased steadily. However, there are no guidelines on their use in many situations such as non small cell lung carcinoma (NSCLC), which frequently alters quality of life markedly. Therefore, a multicentric survey was designed to assess the treatment of anemia and bone metastasis in chemotherapy-treated patients with non-small-cell lung carcinoma. Nine representative centers of the oncology working party of the French respiratory society (Groupe d'Oncologie de la Société de Pneumologie de Langue Française) participated. Inclusion criteria were stage IV NSCLC and at least one course of chemotherapy in the last 3 months. A total of 148 and 50 patients (pts) were included in the anemia and bone metastasis surveys, respectively. Anemia was present in 60.8% of patients, and was not treated in 75%; 15 patients received EPO (10.1%). Independent predictors of EPO use were presence of anemia-related symptoms, hemoglobin level, age and center: the rate of prescription in patients with anemia varied from 13 to 73% between centers. BP were administered in 38% of patients with bone metastasis. Independent predictors of BP use were calcium serum level, pain, and center with a rate of prescription ranging from 0 to 80% between centers. This study reveals that, in France, most patients with anemia are not treated, EPO being seldom prescribed. The use of both EPO and BP is highly variable between centers. Guidelines on the use of these supportive treatments could help improve the care for lung cancer patients receiving chemotherapy.

[Primary non-small-cell lung cancer: analysis of 419 T1 (<or=3 cm) tumors in the KBP-2000-CPHG study]

T1 tumors have the best prognosis among primary non-small-cell lung cancers, basically because surgery is generally possible. Among 5.667 patients with primary lung cancer included in the KBP-2000-CPHG study, we examined the characteristics of 419 T1 tumors, i.e. 9.2% of the non-small-cell cancers. Compared with the group of patients with non-T1 tumors, patients with T1 tumors were younger (p=0.0007). They had an equivalent percentage of squamous-cell tumors but more adenocarcinomas (40.3% versus 35.5%, p=0.05). TNM staging showed that 27.6% of the T1 tumors were metastatic at diagnosis (stage IV) with 12.4% T1N0M1 nad 15.2% T1N1-3M1. For the M0 tumors, 52.2% were T1N0 (stage IA) and 20.1% were T1N1-3. Squamous-cell tumors were significantly more frequent among the T1M1 tumors (p=0.07). More than one quarter (27.6%) of the T1 tumors were in stage IV, pointing out the importance of the initial work-up. This findings suggests we should revisit strategies in order to take into account new diagnostic possibilities. Likewise for the therapeutic strategy. Combinations using chemotherapy, surgery and radiotherapy should be better defined for this group of tumors.

[Primary lung cancer in elderly subjects in France]

INTRODUCTION

There are few data on primary bronchial carcinoma in France. We report here the results of the study KBP 2000-CPHG in which there were 1868 patients aged 70 or more and 338 aged 80 or more.

METHODS

We compared the patients under 70 (Group I) with those aged 70 or more (Group II) as well as with the details of the over 80's.

RESULTS

Group II included significantly more women (17.4% vs 15.2%; p = 0.04), non-smokers (11.2% vs 5.3%; p<0.0001), patients of poor performance status (24.2% vs 14.5%; p<0.0001) and squamous carcinomas (44.5% vs 37.8%; p<0.001) than Group I, but fewer adenocarcinomas (27.2% vs 31.5%; p = 0.009) and as many small cell carcinomas (15.9% vs 16.9%; p = 0.32). In Group II there were less stage III and IV tumours (75.1% vs 78.1%; p = 0.0005) more symptomatic treatment (23.2% vs 6.1%) and radiotherapy alone (12.8% vs 3.8%; p < 0.0001). The results were similar beyond 80 years. On multivariate analysis age, performance status and stage appeared to be independent variables in the choice of curative or symptomatic treatment.

CONCLUSIONS

Age alone is not therefore a limiting factor in the choice of treatment.

Oral vinorelbine in combination with cisplatin: a novel active regimen in advanced non-small-cell lung cancer

BACKGROUND

A phase II trial of alternating i.v. and oral vinorelbine in combination with cisplatin was designed to determine the response rate, safety profile, progression-free survival, overall survival and quality of life (QoL) in advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND METHODS

Fifty-six chemotherapy-naïve patients received cisplatin 100 mg/m(2) and i.v. vinorelbine 25 mg/m(2) on day 1, followed by oral vinorelbine 60 mg/m(2) on days 8, 15 and 22, every 28 days.

RESULTS

After an independent review, the response rate was 33% [95% confidence interval (CI) 20% to 46%]. Median progression-free and overall survival were 5.5 months (95% CI 3.7-6.4) and 8.9 months (95% CI 8.8-11.7), respectively. The most frequent hematological toxicities were neutropenia (grade 3-4 in 73% of patients) and anemia (grade 3-4 in 11% of patients). Grade 3-4 infections and non-hematological toxicities occurred occasionally. QoL for lung cancer related symptoms was stable or improved.

CONCLUSIONS

The efficacy and safety of the alternating vinorelbine schedule (i.v. on day 1, oral on days 8, 15 and 22) in combination with cisplatin in advanced NSCLC are similar to those of the standard regimen using exclusively i.v. vinorelbine, whereas ease of administration and patient comfort may favor the novel approach.

[Epidemiologic of primary bronchial carcinoma management in the general French hospital centers]

INTRODUCTION

The College of General Hospital Respiratory Physicians have conducted a study aimed at a better understanding of the details and modalities of management of patients suffering from bronchial carcinoma in general hospitals in France.

MATERIALS AND METHODS

A prospective epidemiological study was carried out on all the new cases of histologically proven bronchial carcinoma seen in general hospitals in the year 2000. The data were collected by a standardised questionnaire.

RESULTS

137 centres of investigation identified 5 667 patients, mean age 64.3 years, of whom 16% were women. 7.2% of patients were non smokers (with an incidence of 32.3% non-smokers among the women) and 40.3% were ex-smokers. Histologically 16.9% were small cell carcinomas, 40% squamous carcinomas (43.1% among the men, 23.4% among the women, p<0.0001), 30.1% adenocarcinomas (27.2% among the men, 45.3% among the women, p<0.0001). 77.1% of non small cell carcinomas were stages III and IV, and 66.8% of small cell carcinomas were disseminated, with no difference between the sexes.

CONCLUSION

Respiratory physicians in general hospitals manage more than a quarter of the cases of bronchial carcinoma seen annually in France. The number of women affected is high with a significant percentage of non-smokers and adenocarcinomas.

[Standards, Options and Recommendations for the management of stage I or II primary bronchial cancers treated exclusively with radiotherapy]

CONTEXT

The 'Standards, Options and Recommendations' (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French cancer centres and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery.

OBJECTIVES

To develop clinical practice guidelines according to the definitions of the Standards, Options and Recommendations project for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone.

METHODS

Data were identified by searching Medline and personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to independent reviewers, and to the medical committees of the 20 French cancer centres.

RESULTS

The main recommendations for the management of stage I and II non small cell lung carcinoma treated by radiotherapy alone are: 1) The curative external irradiation with a continual course is an alternative to surgery only in the case of medically inoperable tumors or because the patient refuses surgery; 2) The external irradiation of the primary tumor only without the mediastinum could be proposed in peripheral stage IA. In proximal stage IA and IB, external irradiation should be carried out only as part of prospective randomised controlled trials comparing a localised irradiation of the primary tumor with a large irradiation of the mediastinum and the primary tumor. The treated volume must include the macroscopic tumoral volume with or without the microscopic tumoral volume and with a security margin from 1.5 to 2 cm; 3) There is a benefit to delivering a total dose in the primary tumor higher than 60 Gy in so far as the proposed irradiation, taking into account the respiratory function, does not increase the likelihood of severe adverse events due to radiation; and 4) The change in fractionation, the radiochemotherapy combination, the endobronchial brachytherapy with high dose rate alone or with external irradiation could be proposed only as part of prospective controlled trials for tumors classified as stage IB or II.

[Small cell lung cancer revealed by extramembranous glomerulonephritis]

We describe a case of small-cell lung cancer limited to the thorax but with malignant pleural effusion in a 47-year-old man that was revealed by a nephrotic syndrome due to membranous glomerulonephritis (MGN). Chemotherapy led to a partial tumor response with total resolution of the nephrotic syndrome. Tumor relapse did not provoke proteinuria. Primary lung cancer is the cause of about 3% of all cases of MGN and 40% of tumor-related MGN. There are 49 cases of tumor-related MGN in the literature, including 9 cases of small-cell lung cancer.

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.

Equally efficacious asthma management with budesonide 800 micrograms administered by Turbuhaler or with beclomethasone dipropionate > or = 1500 micrograms given through a pressurized metered-dose inhaler with spacer. The French Budesonide Trial Group

To avoid the side effects associated with long-term administration of high doses of inhaled glucocorticosteroids, they should be used at the lowest effective dose. This study compared the clinical efficacy of budesonide given via a dry-powder, inspiratory flow-driven device (Turbuhaler), at a daily dose of 800 micrograms, with beclomethasone dipropionate (BDP) 1500 to 2000 micrograms given via pressurized metered-dose inhaler (pMDI) with spacer to adults requiring the latter dose of BDP to control their asthma. The study was performed as a 2-week run-in, 8-week open, randomized, multicenter, parallel-group design. Adult asthmatics with a forced expiratory volume in 1 second 55% or more of predicted normal and receiving BDP 1500 to 2000 micrograms daily entered the study. After a 2-week run-in, one group continued with BDP and the other was switched to budesonide through the Turbuhaler. After 8 weeks, morning peak expiratory flow (PEF) had increased by 5.9 L/min from a mean of 390 L/min in the budesonide group and by 1.9 L/min from a mean of 402 L/min in the BDP group. No clinically or statistically significant differences between groups were evident with regard to the change in this primary variable. Similarly, only small changes in evening PEF and secondary variables of lung function were seen, with no statistically significant difference between groups. The authors concluded that both treatments were equivalent in managing asthma in adult patients with stable asthma.

Bronchogenic cyst presenting as mediastinal mass with pleural effusion

Mediastinal bronchogenic cysts are usually identified on computed tomography (CT) as well-defined masses of variable density that may contain rim calcifications. Pleural effusion has never been described in association with these cysts. We report two cases of bronchogenic cysts with unusual presentation because of an association with a pleural effusion not explained by pulmonary infection. The patients were studied with CT scan (n = 2) and magnetic resonance imaging (MRI) of the chest (n = 1). In the first case, the pleural effusion directed diagnosis towards lung tumour; and the diagnosis of bronchogenic cyst was made on thoracotomy. In the second case, bronchogenic cyst was suspected on MRI findings. Inflammatory reaction was also suspected on the CT scan, which showed enhancement of the cyst edge. In both cases, surgical excision of the cyst was difficult because of pericystic adhesions to adjacent organs. Therefore, solely on the finding of a pleural effusion, pericystic inflammation had to be suspected.

[Hemoptysis in sarcoidosis. Apropos of 6 cases including 4 with fatal outcome]

Haemoptysis rarely occurs in sarcoidosis. Most cases usually occur in patients with advanced disease and major fibrosis. We observed 6 cases including 5 with fibrosis and 1 with inaugural unilateral lymph node involvement. Haemoptysis is a sign of gravity since it is the second most frequent cause of death described in the literature. In our series 4 of the 6 cases were fatal. Aspergillus colonization of a cavity is the most frequently found aggravating factor. Ideally, surgery is indicated but usually cannot be performed due to the patients respiratory function and the extent of the lesions. Oral drugs have little effect. Certain authors have had success with local, initially intrabronchic anti-aspergillus treatment. CT-guided application is often helpful. Embolization may stop the bleeding but in the long-term, a more or less voluminous haemoptysis often recurs. Other causes of bleeding are rare. Systemic hypervascularization of sarcoidosis lesions has been proposed as one mechanism other than infection. The cause may also be a simple granuloma. Symptomatic initial treatment by embolization is also proposed in these cases. Finally, massive haemoptysis can occur by erosion of the pulmonary artery due to a necrotic sarcoidosis lesion. In our series, surgery was impossible in three patients who died. In the three others, embolization was possible in 2 and the third underwent successful surgery.
