Surgical outcome of lung cancer patients with carcinomatous pleuritis.

In sporadic though non-anecdotal series, long-term survival has been reported for patients operated on for lung cancer with secondary carcinomatous pleuritis. In a retrospective study, we review the outcomes of 24 surgical patients (20 treated with standard lung resection +/- pleurectomy and 4 with extended pleuropneumonectomy) out of 48 individuals affected by pleural spread before or at thoracotomy. We observed a 16.6% major complication rate with no operative mortality; 5-year and median survival were 20% and 21 months, respectively. Time of diagnostic (pre- vs intra/postoperative) or pattern (effusion vs dissemination) of pleural disease, and type of resection (standard vs extended) did not seem to influence the prognosis, while an adenocarcinoma histotype, completeness of excision and N(0-1) were favourable prognostic indicators. Since most (90%) of these IIIB stages are usually associated with N(2-3) and/or unresectable tumour, it would seem reasonable to employ neo-adjuvant treatment as the first approach, reserving surgical treatment to responders. Multicentre studies are necessary to better determine which subgroup of patients with malignant pleuritis can most benefit from surgical therapy.
