Abstract
PURPOSE Despite anatomical differences, truncal soft tissue sarcomas (STS) often are grouped with extremity sarcomas. We evaluated the clinical outcome of patients with truncal STS who underwent gross total resection (GTR) and radiation therapy (RT), with special emphasis on those treated with intensity modulated radiation therapy (IMRT). METHODS From January 1, 2001 to December 31, 2018, 64 patients received GTR and RT, where 48 patients were male, 35 patients were aged ≤ 60 years, and 48 patients had tumors ≤ 10 cm. Sixty-two tumors were high grade, 36 were in the chest wall, 7 in the abdominal wall, and 21 were paraspinal. During surgery, 7 received mesh reconstruction, and 6 received flap closure. R0 resection was achieved in 53 patients. Thirteen patients received chemotherapy. RESULTS With a median follow-up of 57 months, the 5-year actuarial local control (LC) was 71%. In the IMRT subset (50/64, 78%), the 5-year LC for the chest/abdominal wall was 84%, and 69% for the paraspinal subsite. Grade 2+ radiation dermatitis was seen in 21 of 64 (33%) patients, 5 of 64 (8%) developed noninfectious wound complications, 5 of 64 (8%) developed infectious wound complications, and 1 of 64 (2%) developed grade 2 chest wall pain. No additional grade 2+ late toxicity was observed. CONCLUSIONS Based on this study, achieving LC in truncal STS treated with GTR and RT remains challenging even with IMRT (5-year LC: 78%). While the use of IMRT was more promising for tumors of the chest/abdominal wall with 5-year LC of 84%, it was 69% for those located in the paraspinal subsite, indicating a need for further improvement.

Perioperative chemotherapy is not associated with improved survival in high-grade truncal sarcoma. J Surg Res 2018; 231:248-256. [PMID: 30278937 DOI: 10.1016/j.jss.2018.05.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2017] [Revised: 04/30/2018] [Accepted: 05/18/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND The treatment benefit of perioperative chemotherapy (CTX) for truncal soft tissue sarcoma (STS) is not well established. This study evaluates the association of CTX with survival for patients with resected primary high-grade truncal STS. MATERIALS AND METHODS Adult patients with high-grade truncal STS who had curative-intent resection from 2000 to 2016 at seven U.S. institutions were evaluated retrospectively. Patients were stratified by receipt of CTX. Kaplan-Meier curves with log-rank tests were used to compare overall survival (OS) and recurrence-free survival. Logistic regression models were used to evaluate characteristics associated with OS. RESULTS Of patients with primary high-grade truncal STS, 235 underwent curative-intent resections. The most common histology was undifferentiated pleomorphic sarcoma and mean tumor size was 7.8 cm. Thirty percent of the patients received CTX (n = 70). Among patients receiving CTX, 34% (n = 24) had neoadjuvant CTX, 44% (n = 31) adjuvant CTX, and 21% (n = 15) had neoadjuvant and adjuvant CTX. Patients receiving CTX were more likely to receive radiation (51% versus 34%, P = 0.01), have deep tumors (86% versus 73%, P = 0.037) and solid organ invasion (14% versus 3%, P = 0.001). On univariate analysis, patients who received CTX had worse OS (P < 0.01) and a trend toward worse recurrence-free survival (P = 0.08). Margin status was the only variable associated with improved OS on multivariate analysis (odds ratio 4.36, 95% confidence interval 1.56, 12.13, P < 0.01). CONCLUSIONS In this multi-institutional retrospective analysis of resected high-grade truncal STS, receipt of perioperative CTX was not associated with improved OS, which may be related to selection bias. Microscopically negative margin status was the only independent factor associated with OS.
