[Use of intrapleural doxycycline via lavage-drainage in recurrent effusions of neoplastic origin].

27 patients (17 F, 10 M) with a mean age of 65 +/- 11 years and suffering from recurrent pleural effusions were treated with locally administered Doxycycline by lavage-drainage to achieve pleural symphysis (17 adeno-carcinomas, 3 large cell carcinomas; 3 epidermoid cancers; 3 non-Hodgkin's lymphoma; 1 small cell carcinoma). The solution used was a dilution of 50 ml doxycycline in 250 cc of isotonic saline. 22 of the 27 patients could be evaluated long term, 5 were lost to follow up, of whom two had recurred straight away despite local treatment. An immediate response was obtained in 23 out of the 28 patients (85%). Later the absence of recurrence was seen in 90% of the patients evaluated. The incidence of antimitotic therapy did not seem to be the determining factor in the 7 patients who received this in parallel. The duration of drainage was 11 +/- 6 days, the local treatment was well tolerated in the majority of cases. The use of the technique of lavage-drainage of doxycycline could be an alternative in those patients with a malignant pleural effusion whose general condition contra-indicates a symphysis under pleuroscopy.
