Abstract
Background: Soft tissue sarcomas (STS) are rare but aggressive tumors. Although surgery and radiotherapy are standard treatments for localized STS, the role of adjuvant chemotherapy, particularly doxorubicin, in high-grade STS is debated.
Methods: This retrospective study evaluated the effectiveness of single-agent doxorubicin in resectable grade 2 and 3 STS, with a focus on oncologic outcomes. Adults with biopsy-confirmed STS of the extremities or trunk, treated at a tertiary center in Taiwan between January 2004 and March 2020, were included. Primary outcomes were distant metastasis-free survival (DMFS) and overall survival (OS).
Results: The study enrolled 62 patients in either the single-agent doxorubicin adjuvant chemotherapy group (n = 8) or the observation-only group (n = 54). The mean age was 45.4 years in the adjuvant chemotherapy group and 58.2 years in the observation-only group. The 3-year OS was 100% in the chemotherapy group and 60% in the observation group (log-rank P = .064). The 3-year DMFS rate was 75% in the chemotherapy group and 45% in the observation group (log-rank P = .078).
Conclusion: In resectable, high-grade STS of 8 cm or more, single-agent doxorubicin as adjuvant chemotherapy showed a trend toward improved OS and DMFS compared with observation alone; however, statistical significance was not reached.
期刊介绍:
Although laboratory and clinical cancer research need to be closely linked, observations at the basic level often remain removed from medical applications. This journal works to accelerate the translation of experimental results into the clinic, and back again into the laboratory for further investigation. The fundamental purpose of this effort is to advance clinically-relevant knowledge of cancer, and improve the outcome of prevention, diagnosis and treatment of malignant disease. The journal publishes significant clinical studies from cancer programs around the world, along with important translational laboratory findings, mini-reviews (invited and submitted) and in-depth discussions of evolving and controversial topics in the oncology arena. A unique feature of the journal is a new section which focuses on rapid peer-review and subsequent publication of short reports of phase 1 and phase 2 clinical cancer trials, with a goal of insuring that high-quality clinical cancer research quickly enters the public domain, regardless of the trial’s ultimate conclusions regarding efficacy or toxicity.
