[Cohort KBP-2000-CPHG: Evaluation of factors influencing survival in lung cancer].

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.

[Characteristics of mild asthma: clinical signs and medication use. Position statement of the Mild Asthma Working Group (174)].

OBJECTIVE: To update on the state of knowledge in mild asthma (intermittent and persistent mild asthma, according to the GINA classification) review the literature, and the position statement of the French Mild Asthma Working Group. METHODS: The French Mild Asthma Working Group (11 lung specialists, 4 paediatricians, 1 pharmacologist, and 1 general practitioner) selected, analysed, and summarised the literature on the descriptive epidemiology, physiopathology, clinical signs, and management of mild asthma. The position of the working group on the descriptive epidemiology (causal factors excluded) and the nature of the bronchial inflammation has been presented in a previous article. The present article focuses on the clinical features of mild asthma and the use of medication for it. RESULTS: Mild asthma was more frequent, more symptomatic, and less well controlled in children than in adults. Its generally benign evolution may in some (<10%) cases be complicated by severe episodes. Patients with mild persistent asthma require controller medication every day: permanent low-dose inhaled corticosteroid monotherapy is the reference foundation treatment for persistent mild asthma. CONCLUSIONS: The present findings should help clinicians and guide them in their approach to managing this condition.

[Characteristics of mild asthma: descriptive epidemiology and nature of bronchial inflammation. Position of the Mild Asthma Working Group].

INTRODUCTION: Update on the state of knowledge in the mild asthma (intermittent and persistent mild asthma, according to the GINA classification) literature, and position of a French Mild Asthma Working Group. STATE OF THE ART: The French Mild Asthma Working Group (11 lung specialists, 4 paediatricians, 1 pharmacologist, and 1 general practitioner) selected, analysed, and summarised the literature on the epidemiology, physiopathology, clinical signs, and management of mild asthma. The present article shows the position of the working group on mild asthma descriptive epidemiology (causal factors excluded) and the nature of the bronchial inflammation. Clinical signs and medicinal treatments will be presented in a second article. PERSPECTIVES: Between 50% and 75% of asthma patients, depending on the study, present mild asthma. Childhood-to-adulthood cohort monitoring found severity to be unchanged over developmental time. Its generally benign evolution may in some (<10%) cases be complicated by severe episodes. Inflammation and airway-wall remodelling were always found, although of variable intensity, and non-specific (except for absence of infiltration by polymorphonuclear neutrophils). Corticosteroid therapy by inhalation reduces bronchial inflammation, but with little impact on airway-wall remodelling. CONCLUSION: The present findings should help clinicians in identifying and understanding mild asthma.

[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.

[Impact of medical prescription computerisation on the incidence of adverse drug effects].

INTRODUCTION: Adverse drug effects are a significant public health problem. Prescription errors are responsible for a significant proportion of these adverse effects. METHODS: We have aimed to improve the link between generation of and interpretation of a prescription through computerisation. The prescription sheet, which is generated daily, was organised to allow care planning without the need to re-copy out treatments on the sheet. A prescription aid was available which was based on a core group of drugs commonly used in our respiratory service. The aim of the study was to compare the various types of errors observed during 6 weeks of computerized prescriptions (229 files) to a retrospective series of handwritten prescriptions of the service at an identical time (184 files) the previous year. The case-mix was identical for both analysed periods. RESULTS: The total number of technical prescribing errors in the 1,599 handwritten lines (49.27% error) was significantly higher (p<0.001) than the 1,805 computerized prescriptions lines (42.88% error). The errors of copying (p<0.001), eligibility (p<0.001) and incorrect spelling (p<0.05) were the main sources of error which were significantly reduced by computerisation. CONCLUSION: Computerised prescription is likely to reduce the incidence of prescribing errors and adverse drug effects.

[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.

Association between institutionalization and carriage of multiresistant bacteria in the elderly at the time of admission to a general hospital.

The impact of institutionalization on the carriage of multiresistant bacteria among the elderly was assessed prospectively by comparing the carriage rate in institutionalized patients over 70 years of age to the carriage rate in patients over 70 living at home (58 patients/group). Nares, skin, and rectal swabs were obtained within 24 h of admission to the hospital. Among the 20 carriers identified, 75% came from institutions. Significantly, institutionalized patients were incontinent (P < 0.001), less autonomous than those living at home (P < 10(-6)), and had taken antibiotics recently (P < 0.02). The primary characteristics associated with bacterial colonization were institutional living (P < 0.02), having at least one underlying disease (P < 0.001), dependence (Karnofsky index < or = 50; P < 0.02), recent treatment with antibiotics (P < 0.02), and the presence of skin lesions (P < 0.02). Among the risk factors identified, institutionalization can be readily determined upon admission; systematic communication of carrier status of transfer patients would improve overall patient care.

High-frequency ventilation in newborn lambs after intra-uterine creation of diaphragmatic hernia.

Infants with congenital diaphragmatic hernia (CDH) die, because their lungs are hypoplastic and their pulmonary vascular resistance remains elevated after birth. In human newborns, it is difficult to appreciate the benefit of new therapeutic approaches, because the pathological findings are not uniform, the disease is rare and the clinical criteria for poor prognosis with conventional therapy are uncertain. To study the benefit of high-frequency ventilation (HFV) the use of Tolazoline in CDH, we created a diaphragmatic defect in sheep fetuses at 0.6 gestation and studied full-term newborns after a caesarian section. A sternotomy was performed to place catheters and flow probes on the aorta and pulmonary artery and to clamp the ductus arteriosus and the left pulmonary artery. Twins were used as control, and the CDH lambs were either ventilated with conventional ventilation (CV) or HFV. 23 ewes were operated upon with a 22% abortion rate and 31 newborn lambs (10 controls and 21 CDH) were studied. A complete gasometric and hemodynamic study was performed in 23 lambs (7 controls, 8 CDH with CV and 8 CDH with HFV). Clinical and pathological findings of the lambs with CDH were very similar to severe CDH in humans with bilateral lung hypoplasia, severe respiratory distress, high pulmonary vascular resistance and severe hypoxemia. HFV dramatically improved CO2 elimination, allowed less aggressive ventilation, and was associated with higher flows and lower systemic and pulmonary vascular resistance. However, HFV did not improve oxygenation leaving the newborn with severe hypoxemia associated with massive intrapulmonary foramen ovale shunting from right to left.
