Abstract
PURPOSE Brachytherapy is most often applied in the curative or salvage setting, but many forms of brachytherapy can be helpful for symptom palliation. Declining utilization is seen, for multiple reasons, such as lack of awareness, insufficient expertise, or poor access to equipment. High level evidence for many types of palliative brachytherapy has been lacking. The objective of the current study was to review the evidence for utilization and efficacy of brachytherapy to palliate symptoms from cancer. MATERIALS AND METHODS We performed a systematic search in EMBASE and MEDLINE for English-language articles published from January 1980 to May 2022 that described brachytherapy used for a palliative indication in adults with a diagnosis of cancer (any subtype) and at least one symptom related outcome. Individual case reports and conference abstracts were excluded. All publications were independently screened by two investigators for eligibility. RESULTS The initial search identified 3637 abstracts of which 129 were selected for in-depth review. The number of studies (total number of patients) included in the final analysis varied widely by tumor site with the majority (68.2%) involving either lung or esophageal cancer. Despite a limited number of prospective trials that assessed the efficacy of brachytherapy for symptom management, there was a positive effect on palliation of symptoms across all tumor types. There was no clear trend in the number of publications over time. The most commonly cited symptom indications for palliation by brachytherapy were dysphagia, dyspnea, pain and bleeding. CONCLUSIONS Brachytherapy can provide palliation for patients with advanced cancer, across different tumor sites and clinical scenarios. However, high level evidence in the literature to support palliative applications of brachytherapy is lacking or limited for many tumor sites. There appears to be a strong publication bias towards positive studies in favor of brachytherapy. Beyond anecdotal reports and individual practices, outcomes research can further our understanding of the role of brachytherapy in palliating advanced cancers of all types, and should be encouraged.

Esophageal fistula after definitive concurrent chemotherapy and intensity modulated radiotherapy for esophageal squamous cell carcinoma. PLoS One 2021; 16:e0251811.

Abstract
Background The literature regarding esophageal fistula after definitive concurrent chemotherapy and intensity modulated radiotherapy (IMRT) for esophageal squamous cell carcinoma (ESCC) remains lacking. We aimed to investigate the risk factors of esophageal fistula among ESCC patients undergoing definitive concurrent chemoradiotherapy (CCRT) via IMRT technique. Methods A total of 129 consecutive ESCC patients receiving definitive CCRT with IMRT between 2008 and 2018 were reviewed. The cumulative incidence of esophageal fistula and survival of patients were estimated by the Kaplan–Meier method and compared between groups by the log-rank test. The risk factors of esophageal fistula were determined with multivariate Cox proportional hazards regression analysis. Results Median follow-up was 14.9 months (IQR, 7.0–28.8). Esophageal perforation was identified in 20 (15.5%) patients, resulting in esophago-pleural fistula in nine, esophago-tracheal fistula in seven, broncho-esophageal fistula in two, and aorto-esophageal fistula in two patients. The median interval from IMRT to the occurrence of esophageal fistula was 4.4 months (IQR, 3.3–10.1). Patients with esophageal fistula had an inferior median overall survival (10.0 vs. 17.2 months, p = 0.0096). T4 (HR, 3.776; 95% CI, 1.383–10.308; p = 0.010) and esophageal stenosis (HR, 2.601; 95% CI, 1.053–6.428; p = 0.038) at baseline were the independent risk factors for esophageal fistula. The cumulative incidence of esophageal fistula was higher in patients with T4 (p = 0.018) and pre-treatment esophageal stenosis (p = 0.045). There was a trend toward better survival after esophageal fistula among patients receiving repair or stenting for the fistula than those only undergoing conservative treatments (median survival, 5.9 vs. 0.9 months, p = 0.058). Conclusions T4 and esophageal stenosis at baseline independently increased the risk of esophageal fistula in ESCC treated by definitive CCRT with IMRT. There existed a trend toward improved survival after the fistula among patients receiving repair or stenting for esophageal perforation.

Abstract
<b><i>Objective:</i></b> Esophageal fistula is a critical and fatal complication of esophageal cancer. The aim of this meta-analysis was to explore the risk factors for esophageal perforation in esophageal cancer patients treated with radiotherapy. <b><i>Methods:</i></b> Data from the PubMed and Embase databases were retrieved for clinical research published between 1990 and 2018. The Newcastle-Ottawa Scale was used to evaluate the quality of the articles. A meta-analysis was performed using the RevMan 5.3 software provided by the Cochrane Collaboration Network. <b><i>Results:</i></b> Seventeen articles were eligible for the meta-analysis. In these articles, over 35 risk factors for esophageal fistula formation were described and 17 risk factors were analyzed. Significant differences in the odds of developing an esophageal perforation were found with regard to age (OR 2.34, 95% CI 1.08–5.03, <i>p</i> = 0.001), ulcerative type (OR 2.72, 95% CI 1.43–5.16, <i>p</i> = 0.002), histology (OR 4.16, 95% CI 1.14–15.12, <i>p</i> = 0.03), T stage (OR 2.66, 95% CI 1.44–4.91, <i>p</i> = 0.002), short-term response (OR 2.21, 95% CI 1.06–4.62, <i>p</i> = 0.03), chemotherapy regimen (OR 2.80, 95% CI 1.38–5.68, <i>p</i> = 0.005), and stenosis (OR 2.00, 95% CI 1.03–3.89, <i>p</i> = 0.04). <b><i>Conclusions:</i></b> An age of <60–65 years, ulcerative type, squamous cell cancer, T4 stage, incomplete response, fluorouracil-based regimen, and stenosis were associated with an increased risk of esophageal fistula during or after radiotherapy. However, further, large-scale prospective studies are needed to establish the validity of this association.
