Relevance of an intensive postoperative follow-up after surgery for non-small cell lung cancer.

BACKGROUND: Although a minimal follow-up with periodic clinic visits and chest radiographs is usually recommended after complete operation for non-small cell lung cancer, the ideal follow-up has not been defined yet. Objectives of this prospective study were to determine the feasibility of an intensive surveillance program and to analyze its influence on patient survival. METHODS: Follow-up consisted of physical examination and chest roentgenogram every 3 months and fiberoptic bronchoscopy and thoracic computed tomographic scan with sections of the liver and adrenal glands every 6 months. Influence of patient and recurrence characteristics on survival from recurrence was successively analyzed using the log-rank test and a Cox model adjusted for treatment. RESULTS: Among the 192 eligible patients, recurrence developed in 136 patients (71%) and was asymptomatic in 36 patients (26%). In 35 patients, recurrence was asymptomatic and detected by a scheduled procedure: thoracic computed tomographic scan in 10 (28%) patients and fiberoptic bronchoscopy in 10. Fifteen patients (43%) had a thoracic recurrence treated with curative intent. From the date of recurrence, 3-year survival was 13% in all patients and 31% in asymptomatic patients whose recurrence was detected by a scheduled procedure. Asymptomatic recurrences (p < 0.001), female sex (p < 0.001), performance status 2 or less (p = 0.01), and age 61 years or younger (p = 0.01) were shown to be significantly favorable prognostic factors. CONCLUSIONS: This intensive follow-up is feasible and may improve survival by detecting recurrences after surgery for non-small cell lung cancer at an asymptomatic stage.

[Bevacizumab and lung cancer: eligible patients in daily practice]. / Bévacizumab et cancer bronchique: population cible en pratique quotidienne.

BACKGROUND: Combining bevacizumab with platinum-based chemotherapy significantly improves survival for patients with advanced non-squamous non-small cell lung cancer. The objective of this study was to assess the proportion of patients who could receive this combined therapy. METHODS: This was a retrospective single centre analysis of patients treated between 2007 and 2008. Exclusion criteria for bevacizumab included: squamous cell carcinoma, contraindication to platinum-based chemotherapy, uncontrolled hypertension, haemoptysis superior to 2.5 mL, recent surgery, and/or tomodensitometric criteria after independent review by two radiologists (contact with a proximal vessel, tracheobronchial involvement, cavitation). Cardiovascular diseases and central tumour location were not systematically considered as contraindications. RESULTS: Among 194 patients analysed, 21 (10.8%) to 35 (18%) patients were eligible for bevacizumab, whether or not cardiovascular diseases and central tumour location were considered as contraindications. The kappa coefficient was 0.49. CONCLUSION: Even though the proportion of patients who can receive chemotherapy plus bevacizumab may vary according to the eligibility criteria chosen and the interpretation of the CT scan, it is unlikely to exceed 25% of patients in daily practice.
