| pubmed-article:12926218 | pubmed:abstractText | The results of a retrospective non-randomized pair-controlled investigation are discussed. The data on a patient of cytoreductive surgery and another one operated on for symptoms only (control) were compared. Both subjects had to have comparable most important prognostic characteristics, such as gender, age, primary tumor localization and the number and pattern of distant metastases. The study included 34 patients. The surgery group comprised 19 patients (female--13, male--6). Total cytoreductive surgery (5) used standard removal of primary tumor and marginal resection of a segment of the liver (4), or excision of the right lobe (1). Partial surgery (14) involved removal of primary tumor alone. Controls (female--10, male--5) were operated on for symptoms (proctotoreusis--12, shunt--3). No systemic antitumor therapy was given. Concomitant pathology, its absence as well as postoperative complications were excluded from consideration. Median survival in control was 5.2 mo, total or partial surgery--13.5 mo (p = 0.00083). In a longer perspective, it was 27.0 mo for total surgery and 12.6 mo--partial (p = 0.00295), while after partial surgery it was longer than for symptomatic treatment--5.2 mo (p = 0.0029). No correlation was established between survival, on the one hand, and gender, age or primary tumor localization, on the other (p(0.005). However, a relationship was found between survival and extent of excision (p = 0.01737). | lld:pubmed |
