Nonrhabdomyosarcomatous abdominopelvic sarcomas: Analysis of prognostic factors

Background: Data concerning treatment outcome and prognostic factors in sarcomas of abdomen and pelvis are sparse in literature.Methods and Results: Of 696 patients with nonrhabdomyosarcomatous soft tissue sarcoma registered at our center between June 2003 and December 2012, 112 (16%) patients of sa...

description Background: Data concerning treatment outcome and prognostic factors in sarcomas of abdomen and pelvis are sparse in literature.Methods and Results: Of 696 patients with nonrhabdomyosarcomatous soft tissue sarcoma registered at our center between June 2003 and December 2012, 112 (16%) patients of sarcomas arising from abdomen and pelvis were identified, of which 88 patients were analyzed for treatment outcome and prognostic factors. The median age was 40 years (range: 1–78 years) with a male: female ratio of 0.7:1. Twenty-one (24%) patients were metastatic at baseline. The most common tumor sites were retroperitoneum in 70% patients and abdominal wall in 18% patients. Leiomyosarcoma was the most common histological subtype in 36% patients followed by liposarcoma in 17% patients. Thirty-five (40%) patients had Grade III tumors. Forty-six (52%) patients underwent surgical resection. At a median follow-up of 43 months (range: 2–94 months), the 5-year event-free survival (EFS) and overall survival (OS) were 35% and 42%, with a median of 22 months and 43 months, respectively. Multivariate analysis identified male gender (P - 0.03, hazard ratio [HR] - 0.46, 95% confidence interval [CI] - 0.23–0.92), baseline metastatic disease (P - 0.01, HR - 2.98, 95% CI - 1.27–6.98) and Grade III tumors (P - 0.02, HR - 1.84, 95% CI - 1.08–3.13) as factors associated with poor EFS, whereas baseline metastatic disease (P < 0.001, HR - 5.45, 95% CI - 2.31–12.87) and unresectability (P - 0.01, HR - 2.72, 95% CI - 1.27–5.83) were associated with poor OS. Conclusion: This is a single-institutional study of patients with abdominopelvic sarcomas where gender was identified as a new factor affecting survival apart from baseline presentation, histologic grade, and surgical resection.
