Background. A positive influence of anticoagulant treatment in small cell lung cancer (SCLC) has been sug gested by experimental and clinical data.
Methods. In a multicenter clinical trial, 277 patients with SCLC were randomized either to receive or not to receive subcutaneous heparin injections for 5 weeks at effective doses, which were monitored by blood coagulation tests. All patients received one of the two chemotherapy regimens studied in this trial, for eight courses in the case of patients with complete or partial response, and subsequently were randomized to receive delayed thoracic radiotherapy after these eight courses.
Results. In comparison to the 139 patients who did not receive heparin, the 138 patients who received anticoagulant treatment obtained better complete response rates (37% vs. 23%, P = 0.004), better median survival (317 days vs. 261 days, P = 0.01), and better survival rates at 1, 2, and 3 years (40% vs. 3070, 11% vs. 9% and 9% vs. 6%, respectively). At subgroups analysis, the results on survival were obtained for limited forms (P = 0.03) but not for extensive diseases ( P = 0.31). No important bleed ing or thrombocytopenia was related to heparin treatment.
Conclusions. These results confirm the value of anticoagulant treatment in SCLC, already suspected for warfarin and now proven for heparin, but the modes of administration and the biologic explanations for this activity still warrant further investigation.
Chronic obstructive pulmonary disease (COPD), lung cancer, asthma and pulmonary tuberculosis are common pulmonary diseases that are caused or worsened by tobacco smoking. Growing observational evidence suggests that symptoms and prognosis of these conditions improve upon smoking cessation. Despite increasing numbers of (small) randomised controlled trials suggesting intensive smoking cessation treatments work in people with pulmonary diseases many patients are not given specific advice on the benefits or referred for intensive cessation treatments and, therefore, continue smoking. This is a qualitative review regarding smoking cessation in patients with COPD and other pulmonary disorders, written by a group of European Respiratory Society experts. We describe the epidemiological links between smoking and pulmonary disorders, the evidence for benefits of stopping smoking, how best to assess tobacco dependence and what interventions currently work best to help pulmonary patients quit. Finally, we describe characteristics and management of any "hardcore" smoker who finds it difficult to quit with standard approaches. @ERSpublications Smoking cessation is crucial for respiratory patients: every patient must be given advice and help to quit http://ow.ly/ITgsW
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
