Chemical pleurodesis is an effective treatment of malignant pleural effusions, but indications must be individualised to optimise its results. The aim of the present study was to investigate the relationship of various prognostic features with both the response rate to pleurodesis and the probability of patient survival. A non-concurrent cohort study was carried out in which 120 evaluable patients with malignant pleural effusion underwent pleurodesis. Lung (40%), breast (26.6%), and unknown primary site (12.5%) carcinomas were the most frequent neoplasms. Clinical data and pleural fluid parameters were analysed. Median overall survival was 9 months. Pleural fluid glucose (<60 mg/dl), Karnofsky performance status (<70), size of the effusion in chest radiographs (massive effusion), pleural fluid pH (<7.20), presence of concomitant alterations in chest radiographs, and pleural lactic acid dehydrogenase levels (>600 U/l) showed a significant association with the probability of failure. Patients with these features, along with those having non-chemosensitive tumours (in particular, non-small cell lung cancer), had a significantly worse actuarial survival. This study confirms that some pretreatment clinical data and pleural fluid parameters can predict both the outcome of pleurodesis and the survival of patients with malignant pleural effusion.
Malignant pleural effusions are commonly managed with tube thoracostomy drainage followed by chemical pleurodesis. Both tetracycline and bleomycin have been shown to be effective for intrapleural instillation, although neither agent has definitively proved advantages over the other. The aim of the present study was to compare these two agents in terms of response rate and toxicity profile.A prospective, randomized trial was carried out in a single centre. Between May 1993 and January 1996, 62 evaluable patients with proved malignant pleural effusion were allocated to receive either intrapleural tetracycline (1.5 g) or bleomycin (60 mg) after the same drainage procedure. Demographic, clinical and fluid parameter data were comparable in both groups. Response was evaluated at 1, 3 and 6 months after pleurodesis.Mean survival and time to relapse did not differ between the two groups. No statistically significant differences were found in terms of efficacy at each evaluation time. Overall, 16 (52%) and 20 (64%) patients had a recurrence of pleural effusion during follow-up in the tetracycline and bleomycin arms, respectively. Fever was most common in bleomycin-treated patients (p=0.024) while pain was most frequent in the tetracycline arm (nonsignificant).Since no study agent was superior to the other in this trial, we suggest that economic costs, drug availability and medical skill should be considered in the choice of a sclerosing agent.
Intravesical instillation of bacillus Calmette-Guérin (BCG) vaccine has been shown to be an effective treatment of superficial bladder cancer. However, it is not free of side-effects and complications. We present the case of a 62-year-old man who developed disseminated pulmonary granulomas after local BCG immunotherapy for recurrent papillary bladder cancer.
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.
