Clinical characteristics and quality of life in women with COPD: an observational study.

BACKGROUND: The impact of COPD on patient's quality of life is well established, but gender differences have received little attention. METHODS: To describe factors associated with the health-related quality of life by gender: A cross-sectional observational study (NCT01007734) was conducted in COPD patients followed by pulmonologists. The first patient included had to be a woman. Data concerning the patient, COPD and their management were collected by the physician. The patient had to fill in several questionnaires: Saint-George Hospital respiratory Questionnaire (SGRQ-C), and motivation to quit smoking. RESULTS: Four hundred and thirty patients were included: mean age 63.9 ± 11.3 years; 57.4% were women. Women were significantly younger than men (61.9 vs. 66.6) and their tobacco use was lower (37.1 vs. 40.4 PY). Cardiovascular comorbidities were more frequent in men while osteoporosis, anxiety and depression were frequent in women. The frequency of cough, sputum and the severity of dyspnea did not differ significantly between genders. Lung function impairment was less severe in women than in men (mean FEV1 52% predicted normal vs. 47. 8%). Anxiety score was higher (score 9.8 vs. 7.1) and quality of life (SGRQ-C) more impaired in women (scores 50.6 vs. 45.4; p < 0.02) than in men. Moreover, in multivariate analysis, chronic sputum was associated with higher SGRQ-C scores in women but not in men. CONCLUSIONS: This study underlines that despite less airflow limitation, quality of life is more impacted by chronic sputum in women than in men.

Major and prolonged response to pemetrexed in two cases of lung adenocarcinoma with bronchioloalveolar carcinoma features.

Bronchioloalveolar carcinoma (BAC) and adenocarcinoma mixed subtype with bronchioloalveolar features (ADC-WBF) represent a unique anatomo-clinical entity accounting for some 20% of non-small cell lung cancers (NSCLC). These tumors seem less sensitive to chemotherapy than other NSCLC. We report two cases of advanced ADC-WBF treated with second-line and fourth-line pemetrexed. Major and durable radiological response associated with clinical and functional improvement was achieved in both patients, without important drug toxicity. After treatment arrest, the two patients experienced progressive disease but responded to retreatment with pemetrexed. Recent data suggest that paclitaxel-based chemotherapy and epidermal growth factor receptor tyrosine kinase inhibitors could be an acceptable therapeutic strategy in unresectable CBA and ADC-WBF. The cases reported here and preclinical findings suggest a therapeutic efficacy of pemetrexed in these tumors. Prospective studies are required to evaluate this hypothesis.
