Much shorter radiation treatment found to be safe, effective for people with soft tissue sarcoma

In this study at UCLA, a national leader in the care of patients with sarcoma, researchers used a condensed five-day radiation regimen that considerably cuts down the length of treatment and the time to surgery.“Shortening the radiation therapy from five weeks to five days has been a very meaningful change for patients,” said lead author Dr. Anusha Kalbasi, assistant professor of radiation oncology in the division of molecular and cellular oncology. “Five weeks of daily treatments is a burdensome com mitment for patients. The daily back-and-forth can be expensive and time consuming, and it can really interfere with work, school or parenting. So finding a way to safely shorten the radiation treatment is a significant advancement in improving the quality of care for patients with hard-to-treat can cers like sarcoma.”Researchers enrolled 52 adults at UCLA diagnosed with a soft tissue sarcoma of the limbs or trunk — where these tumors most commonly occur — that was localized and had not spread to other parts of the body. The participants underwent a condensed form of radiation therapy for five days, followed by surgery. The team then analyzed and followed the cohort for an average of 2 1/2 years.They found less than 6% of the patients with at least two years of follow-up on the clinical trial had a recurrence of their tumor, which is on par with studies using the conventional five-week regimen, Kalbasi said.“The main reason we treat sarco...

Authors: Saiz AM, Gingrich AA, Canter RJ, Kirane AR, Monjazeb AM, Randall RL, Thorpe SW Abstract Radiation therapy (RT) is advocated in the multimodal treatment of high-grade soft tissue sarcoma (STS), but its role may be less clear in chemotherapy-sensitive STS such as extraskeletal Ewing sarcoma (EES). The purpose of this study was to determine the role of RT on overall survival (OS) in localized EES adult patients treated with chemotherapy and surgery. Adult patients diagnosed with EES and reported to the National Cancer Database from 2004 to 2014 were evaluated. All patients were treated with surgical resection...

Conclusions: The proposed nomogram is a reliable and robust tool for accurate prognostic prediction in patients with extremity soft tissue LMS. Introduction Soft tissue leiomyosarcoma (LMS) is an aggressive sarcoma, which originates from smooth muscle cells (1). Soft tissue LMS accounts for about 5–10% of all soft tissue sarcomas (2). It occurs in different sites, including the retroperitoneum, intraabdominal sites, and extremities (3). Extremity LMS comprised about 10–15% of extremity sarcomas, with a preference for the lower limb (4–6). Extremity LMS tends to have a better prognosis than uterine...

Conclusion: Fat fraction on MRI corresponded to fat content on histology and therefore contributes to lesion characterization. Measurement repeatability was excellent for ADC; this parameter increased significantly post-radiotherapy even in disease categorized as stable by size criteria, and corresponded to cellularity on histology. ADC can be utilized for characterizing and assessing response in heterogeneous retroperitoneal sarcomas. Introduction Soft-tissue sarcomas are often highly heterogeneous tumors with variable components that can include cellular tumor, fat, necrosis, and cystic change. In many soft-tissue ...

ConclusionsMultimodal therapy for DSRCT consisting of multiagent neoadjuvant chemotherapy, CRS/HIPEC, adjuvant chemotherapy, and radiation therapy is associated with potential cumulative toxicity. Recurrence after resection is common. Prolonged parenteral nutrition may be necessary, and late gastrointestinal and genitourinary complications may require additional treatment.

Conclusions: The addition of vascular-targeted AuNPs significantly improved the treatment effect of liposomal doxorubicin after RT, consistent with the increased liposome accumulation observed in tumors in the imaging study. Using this approach with a liposomal drug delivery system can increase specific tumor delivery of chemotherapeutics, which has the potential to significantly improve tumor response and reduce the side effects of both RT and chemotherapy.

ConclusionsThe use of PARP inhibitors in advanced stage STSs, alone or combined in multimodal treatments, is of great interest and warrants further investigations.
