    Abstract: Neoadjuvant radiation (NRT) is frequently utilized in soft tissue sarcomas to increase local control. Its utility in cutaneous and soft tissue angiosarcoma remains poorly defined. Methods This retrospective cohort study was performed using the National Cancer Database (2004–2016) evaluating patients with clinically localized, surgically resected angiosarcomas. Factors associated with receipt of NRT in the overall cohort and margin positivity in treatment naïve patients were identified by univariate and multivariable logistic regression analyses. Survival was assessed using Kaplan–Meier analysis. Results Of 597 patients, 27 (4.5%) received NRT. Increasing age (odds ratio [OR] 0.95, p  = 0.025), tumor size more than or equal to 5 cm (OR 3.16, p  = 0.02), and extremity tumor location (OR 3.99, p  = 0.04) were associated with receipt of NRT. All patients who received NRT achieved an R0 resection ( p  = 0.03) compared with 17.9% of patients without NRT. Factors associated with risk of margin positivity included tumor size more than or equal to 5 cm (OR 1.85, p  = 0.01), and head/neck location (OR 2.24, p  = 0.006). NRT was not significantly associated with improved survival ( p  = 0.21). Conclusions NRT improves rates of R0 resection but is infrequently utilized in cutaneous and soft tissue angiosarcoma. Increased usage of NRT, particularly for patients with lesions more than or equal to 5 cm, or head and neck location, may help achieve complete resections.

    Abstract: Many patients with high‐risk soft tissue sarcoma (STS) develop distant metastases. Meta‐analyses suggest that chemotherapy confers a small survival benefit, though few studies focus on neoadjuvant chemotherapy (NCT). There has been more frequent use of neoadjuvant radiation therapy (NRT) in STS, but the utility of NCT for these patients remains unclear. Methods Patients with stage II−III trunk/extremity STS who underwent NRT and resection were identified using the National Cancer Database (2006−2019). Predictors of NCT were analyzed using logistic regression. Change in rate of NCT use over time was assessed using log‐linear regression modeling. Survival was examined using Kaplan−Meier (KM) and Cox proportional hazard modeling. Results Of 5740 patients, 25% underwent NCT. The overall median age was 62, 55% of patients were male, and 67% had stage III disease. The most common histological subtypes were fibrosarcoma/myxofibrosarcoma (39%) and liposarcoma (16%). Use of NCT decreased by 4.0% per year throughout the study period ( p   〈  0.01). Predictors of NCT included younger age (median 54, IQR 42−64 vs. median 65, IQR 53−75, p   〈  0.01), treatment at an academic center (odds ratio [OR] 1.5, p   〈  0.01), and stage III disease (OR 2.2, p   〈  0.01). Histologic predictors of NCT included synovial sarcoma (52%) and angiosarcoma (45%). With a median follow‐up time of 77 months, NCT was associated with improved 5‐year survival compared to NRT alone on KM analysis (70% vs. 63%, p   〈  0.01). This difference persisted on multivariate analysis (hazard ratio 0.86, p  = 0.027) and after propensity matching (70% vs. 65%, p  = 0.0064). Conclusion Despite risk of distant failure in high‐risk STS, use of NCT has decreased over time in patients receiving NRT. In this retrospective analysis, NCT was associated with a modestly improved overall survival.

    Abstract: There has been limited progress in the development of novel therapeutics for the treatment of sarcomas. A review of phase I and II clinical trials for sarcomas may give insight into factors influencing sarcoma drug development. Methods An exhaustive analysis of phase I and II clinical trials testing drugs for human sarcoma patients between 1 January 2000 and 1 June 2018 was performed using the PubMed search engine, the Thomson Web of Science, and the National Clinical Trials registry. Recorded outcomes included tested drugs, tested histological subtypes, whether the drug was initially developed for sarcoma, reported funding sources, and whether studies led to phase III trials. Results Out of 238 studies meeting inclusion criteria, 87% (207 studies) reported funding sources. Of these, 59.9% (124/207) reported industry funding, 52.7% (109/207) reported government funding, and 27.5% (57/207) reported private funding. Only 5% (12/238) of phase I and II trials resulted in phase III trials, with 11 of 12 studies funded by industry. Approximately 90% (214/238) of studies tested drugs that were not initially tested in sarcoma, and 60.1% (143/238) of studies grouped different sarcoma histological subtypes together in the same study. Conclusion Industry has funded the majority of phase I and II sarcoma clinical trials that have led to phase III trials. There was a high rate of drugs approved for other cancers and then secondarily tested in sarcoma. Most trials tended to group different sarcoma subtypes rather than studying each subtype separately.

    Abstract: Wound complications represent a major source of morbidity in patients undergoing radiation therapy (RT) and surgical resection of soft tissue sarcomas (STS). We investigated whether factors related to RT, surgery, patient comorbidities, and tumor histopathology predict the development of wound complications. An observational study of patients who underwent STS resection and RT was performed. The primary outcome was the occurrence of any wound complication up to four months postoperatively. Significant predictors of wound complications were identified using multivariable logistic regression. Sixty-five patients representing 67 cases of STS were identified. Median age was 59 years (range 22–90) and 34 (52%) patients were female. The rates of major wound complications and any wound complications were 21% and 33%, respectively. After adjusting for radiation timing, diabetes (OR 9.6; 95% CI 1.4–64.8; P = 0.02 ), grade ≥2 radiation dermatitis (OR 4.8; 95% CI 1.2–19.2; P = 0.03 ), and the use of 3D conformal RT (OR 4.6; 95% CI 1.1–20.0; P = 0.04 ) were associated with an increased risk of any wound complication on multivariable analysis. These data suggest that radiation dermatitis and radiation modality are predictors of wound complications in patients with STS.

    Abstract: Current guidelines do not recommend routine surveillance imaging as part of follow-up care for patients treated for locoregional endometrial carcinoma. This study seeks to determine the potential benefit of routine surveillance imaging by evaluating outcomes of patients whose recurrences were detected on routine surveillance compared to those whose recurrences were identified after presenting with symptoms. Materials/Methods We conducted a retrospective review of patients who developed recurrence after surgical treatment, with or without adjuvant therapy, for locoregional endometrial carcinoma. A total of 149 patients were identified with adequate clinical information regarding the recurrence. Cox proportional hazards regression analysis was used to estimate overall survival and progression-free survival. Results The median age of patients at diagnosis was 69.2 years (range, 38.0-99.5 years). Initial stages included stage I, 49.7%; stage II, 10.1%; stage III, 38.3%; and stage IV, 1.3%. Histologic diagnoses included endometrioid adenocarcinoma, 48.3%; and other diagnoses (including papillary serous carcinoma, clear cell carcinoma, and carcinosarcoma), 51.7%. Patients were initially treated with a variety of therapies: surgery alone in 20.8%, surgery and radiation in 25.5%, surgery and chemotherapy in 12.1%, and trimodality therapy in 41.6%. Sites of recurrence included 20.8% vaginal, 14.8% pelvic and 64.4% distant sites. Recurrences were detected asymptomatically in 86 patients (57.7%) and symptomatically in 63 patients (42.3%). Of those detected asymptomatically, 80.2% were detected by imaging. Overall, when comparing symptomatic versus asymptomatic recurrences, there was no difference in overall survival (hazard ratio, 1.24; 95% confidence interval, 0.84-1.83; P = 0.29) or progression-free survival (hazard ratio, 1.14; 95% confidence interval, 0.77-1.70; P = 0.52). Conclusions Patients who develop asymptomatic recurrences of their endometrial carcinoma do not seem to have a better prognosis than those who present with symptomatic recurrences. Thus, these results do not support routine imaging surveillance for patients treated for locoregional endometrial carcinoma. Further prospective evaluation is needed.

    Abstract: Gut microbial diversity is associated with improved response to immune checkpoint inhibitors (ICI). Based on the known detrimental impact that antibiotics have on microbiome diversity, we hypothesized that antibiotic receipt prior to ICI would be associated with decreased survival. Methods Patients with stage III and IV melanoma treated with ICI between 2008 and 2019 were selected from an institutional database. A window of antibiotic receipt within 3 months prior to the first infusion of ICI was prespecified. The primary outcome was overall survival (OS), and secondary outcomes were melanoma-specific mortality and immune-mediated colitis requiring intravenous steroids. All statistical tests were two-sided. Results There were 568 patients in our database of which 114 received antibiotics prior to ICI. Of the patients, 35.9% had stage III disease. On multivariable Cox proportional hazards analysis of patients with stage IV disease, the antibiotic-exposed group had statistically significantly worse OS (hazard ratio [HR] = 1.81, 95% confidence interval [CI] = 1.27 to 2.57; P & lt;.001). The same effect was observed among antibiotic-exposed patients with stage III disease (HR = 2.78, 95% CI = 1.31 to 5.87; P =.007). When limited to only patients who received adjuvant ICI (n = 89), antibiotic-exposed patients also had statistically significantly worse OS (HR = 4.84, 95% CI = 1.09 to 21.50; P =.04). The antibiotic group had a greater incidence of colitis (HR = 2.14, 95% CI = 1.02 to 4.52; P =.046). Conclusion Patients with stage III and IV melanoma exposed to antibiotics prior to ICI had statistically significantly worse OS than unexposed patients. Antibiotic exposure was associated with greater incidence of moderate to severe immune-mediated colitis. Given the large number of antibiotics prescribed annually, physicians should be judicious with their use in cancer populations likely to receive ICI.

    Abstract: The use of upfront chemotherapy for primary localized soft tissue sarcoma (STS) of the extremity and trunk is debated. It remains unclear if chemotherapy adds clinical benefit, which patients are likely to benefit, and whether the timing of therapy affects outcomes. We used the National Cancer Database (NCDB) to examine the association between overall survival (OS) and chemotherapy in 5436 patients with the five most common subtypes of STS with primary disease localized to the extremity or trunk, mirroring the patient population of a modern phase 3 clinical trial of neoadjuvant chemotherapy. We then examined associations between timing of multi-agent chemotherapy (neoadjuvant or adjuvant) and OS. We used a Cox proportional hazards model and propensity score matching (PSM) to account for covariates including demographic, patient, clinical, treatment, and facility factors. In the overall cohort, we observed no association between multi-agent chemotherapy or its timing and improved OS. Multi-agent chemotherapy was associated with improved OS in several subgroups, including patients with larger tumors ( 〉 5 cm), those treated at high-volume centers, or those who received radiation. We also identified an OS benefit to multi-agent chemotherapy among the elderly ( 〉 70 years) and African American patients. Multi-agent chemotherapy was associated with improved survival for patients with tumors 〉 5 cm, who receive radiation, or who receive care at high-volume centers. Neither younger age nor chemotherapy timing was associated with better outcomes. These ‘real-world’ findings align with recent randomized trial data supporting the use of multi-agent chemotherapy in high-risk patients with localized STS.
