Paraneoplastic syndromes (PNSs) associated with mesenchymal tumors are uncommon. Previous reports sporadically described inflammatory PNSs with elevated serum C‐reactive protein (CRP) levels and leukocytosis in patients with inflammatory malignant fibrous histiocytoma (MFH) of soft tissue; however, the relationship between other subtypes of MFH and PNS has not been extensively investigated. Forty‐six patients with primary MFH of soft tissues who underwent radical surgery were retrospectively analyzed. These patients were divided into 2 groups according to preoperative serum CRP level: normal (<1.0 mg/dl) and elevated (≥1.0 mg/dl). The correlation between serum CRP level and several clinicopathologic factors was analyzed. Correlation between preoperative serum CRP level and metastasis‐free and overall survival was also investigated by univariate and multivariate analyses. Elevated preoperative serum CRP levels were found in 65% of patients with a mean of 3.7 mg/dl. There were statistically significant relationships regarding tumor size, depth, histologic subtypes, grade, stage and metastatic rate among normal and elevated CRP groups ( p < 0.001, p < 0.02, p < 0.005, p < 0.001, p < 0.001 and p < 0.05, respectively). When the tumor was removed, the elevated CRP level subsided into the normal range and other abnormal laboratory findings diminished in all cases. In 11/14 relapsed cases that showed elevated CRP preoperatively, the serum CRP level re‐elevated with tumor relapse. The normal CRP group showed significantly more favorable prognosis than the elevated CRP group in metastasis‐free and overall survival on univariate analysis ( p < 0.02, p < 0.05, respectively). Patients with MFH frequently present with an inflammatory PNS, such as elevated serum CRP level, which can be a useful marker of disease activity and a valuable prognostic indicator. © 2002 Wiley‐Liss, Inc.
