Abstract

Aim: Superficial soft tissue sarcomas (S-STS) are generally considered low-risk tumors and have an excellent prognosis when treated with appropriate surgery and adjuvant therapy. However, they are often misdiagnosed then mistreated, leading to significant morbidity. This study aims to examine the patterns of care and outcomes of patients with S-STS, comparing those initially managed through sarcoma units versus elsewhere.<br />Methods: Patients with S-STS from Prince of Wales Hospital in NSW (1995-2013) and Peter MacCallum Cancer Centre in Victoria (2009-2013) were identified from a national sarcoma database. Baseline variables, treatment and disease outcomes were recorded. Statistical tests performed included univariate and multivariate analyses, chi-square tests, as well as the Kaplan-Meier method for 5-year local recurrence and survival rates.<br />Results: Eighty-nine patients were identified, with 35% initially managed at a sarcoma unit and 65% elsewhere. Patients initially managed at sarcoma units had larger tumors (>5 cm 39% vs 17%; P  =  0.036) with a trend to higher grade (61% vs 48%; P = 0.39). Patients that were initially managed outside a sarcoma unit more often underwent open surgical biopsies (P < 0.0005), had multiple operations (P < 0.0005) and had higher rates of local recurrences (24% vs 6.5%, P  =  0.038). They also had lower 5-year local recurrence-free survival rates (P = 0.022), but had higher metastasis-free survival (P = 0.014). On multivariate analysis, only larger STS size and male gender predicted for poorer metastasis-free survival (P = 0.042 and 0.018, respectively).<br />Conclusion: Patients with S-STS initially managed outside specialized sarcoma units undergo more operations, with risk of greater morbidity, and have greater risk of local recurrence.<br /> (© 2018 John Wiley & Sons Australia, Ltd.)
