RESUMEN
BACKGROUND: Lung cancer in the elderly is considerably increasing in frequency, representing a public health issue. Those patients are underrepresented in clinical trials and probably not optimally treated. METHODS: We performed a survey of the management and the outcome of lung cancer patients aged 70 and more in France between August 2002 and September 2003 according to age categories (70-74, 75-79 and > or =80 years). One thousand six hundred and twenty-seven patients were analysed for descriptive data and 1595 for survival. RESULTS: Median age was 75 (70-96) and male:female ratio was 4.26 with a decrease across the age categories from 5.1 to 3.0. Tobacco-linked comorbidities were frequent. The median value of Charlson's index was 2. About 58% had a performance status (PS) 0 or 1, 30% a PS 2 and 12% a PS>2. The proportion of never-smokers (11.6%) increased significantly with age categories. Regarding imaging procedures, as much as 83.3% of the patients had at least a chest CT-scan and a brain CT-scan (or MRI) and an abdominal ultrasound or CT-scan. Best Supportive Care (BSC) as only treatment was administered to 16.1% of the patients. Among patients specifically treated, 22.9% were operated, 21.8% received mediastinal irradiation and 71.5% chemotherapy. Overall, median survival time was 9.14 months with 23.5% deaths occurring before 3 months. Low category of age, good PS, non-smoking and high body mass index (BMI) were favorable independent prognostic factors of survival. Age, PS and tobacco smoking were prognostic of early death. CONCLUSIONS: A large majority of elderly lung cancer patients in France are managed like younger counterparts regarding diagnostic procedures and treatment. Age remains an independent prognostic factor as well for overall survival as for early death.

BACKGROUND: The authorities advocate a minimalist attitude towards the follow-up of resected bronchial carcinoma (clinical examination and chest x-ray). A survey showed that 70% of French respiratory physicians have chosen to use the CT scanner and often endoscopy. The published data are equivocal and are often based on retrospective studies. Lung cancer is a good model for a study of post-operative surveillance. Recurrences often occur in easily observed areas, they may be detected while still asymptomatic and are sometimes potentially curable. Second primary tumours may develop at the same site. METHODS: The Intergroupe Francophone de Cancerologie Thoracique (IFCT) has initiated a trial comparing simple follow-up (clinical examination, chest x-ray) with a more intensive follow-up (CT scan, fibreoptic bronchoscopy). The surveillance will take place every 6 months for 2 years and then annually until 5 years. EXPECTED RESULTS: The main aim is to determine whether intensive follow-up improves patient survival. The opposite question is equally important. If an expensive and demanding follow-up does not affect the chances of cure these results will influence our practice.

Addition of chemotherapy to the treatment of non-small-cell lung cancer (NSCLC) resulted in a modest but clear improvement in the survival of selected patients. To ascertain if this translates to improved survival in the whole population of patients, we conducted a retrospective population-based study of a sample of 1738 patients diagnosed with primary NSCLC in a French department between 1982 and 1997. The proportion of women, metastatic cases and adenocarcinoma changed significantly over time, as did their management: use of chemotherapy alone increased from 9.7 to 28.1% (P<0.0001), while the use of radiotherapy alone decreased from 32.2 to 9.4% (P<0.0001). The 5-year survival probability was 15.7 % for all patients and 32.6% for those with resectable disease. The 1- and 2-year survival probabilities were 38.2 and 15.6% in locally advanced disease, and were, respectively, 16.8 and 5.2% in metastatic disease. Disease extent and histological subtype were significant independent prognostic factors. Survival of resectable disease was longer among patients treated with surgery or surgery plus chemotherapy, while better outcomes for locally advanced disease were associated with radiation plus chemotherapy. In metastastic disease, patients treated by classical agent without platin or palliative care only had the shortest survival. Despite changes in treatment in accordance with the state-of-the-art, overall survival did not improve over time. It is not unlikely that more patients with bad PS were diagnosed during the latter end of the study period. This could at least partially explain the absence of detection of an overall improvement in survival.

Recent analyses of series of small-cell lung cancer (SCLC) patients included in clinical trials have shown improved survival over time, but it has been impossible to determine whether this was due to selection biases, stage migration, or true therapeutic improvement. To determine if there has been a true improvement of survival over time, we reviewed the medical records of all consecutive patients diagnosed with SCLC between 1981 and 1994 in the Bas-Rhin in France. Among the 787 patients (median age 63), there was no significant period effect for sex, age, or stage. Staging work-ups became increasingly thorough (significant period effect). The mean number of investigations and of tumour sites detected correlated significantly. The chemotherapy rate increased (from 76.4% in 1981-1983 to 91.7% in 1993-1994, P = 10(-5)) and mediastinal irradiation decreased (to roughly 25% of patients after 1983). Median survival time increased for the overall population from 6.6 months in 1981-1983 to 11.3 months in 1993-1994 (P = 10(-5)), for patients with limited disease (LD) from 9.2 (P = 0.002) months to 14.0 months, and for those with extensive (ED) disease from 3.5 months to 9.6 months (P = 10(-5)). Significant independent prognostic factors were disease extent, clinical trial participation, period, type of chemotherapy, and mediastinal irradiation in LD. Survival time has truly improved as 'state of the art' management of SCLC has changed.
