JAK2/STAT3 in position of arsenic-induced mobile or portable expansion: a systematic evaluation as well as meta-analysis.
mpared with vaginal brachytherapy alone (five studies (n=463); OR 0.78 (95% CI 0.34 to 1.80); I2=48%). CONCLUSIONS External beam radiotherapy with or without vaginal brachytherapy decreased the locoregional recurrence threefold for stage II endometrial cancer, regardless of pelvic lymph node assessment. Most women who suffered recurrence locoregionally had a least one high risk factor. CCT128930 Vaginal brachytherapy alone may be sufficient therapy for node negative stage II endometrial cancer without uterine risk factors, while those with uterine risk factors should be considered for external beam radiotherapy with or without vaginal brachytherapy to improve locoregional control. © IGCS and ESGO 2020.

The study prescribed and analysed the results of this novel technique for primary cytoreductive surgery. METHODS The study included 208 patients operated between January 2015 and December 2017 in Charité, Berlin. The TROMP operation was performed in 58 patients, whereas the other 150 patients were operated with the conventional cytoreductive method. RESULTS The complete tumor resection rate accounts for 87.9% in TROMP group and 61.3% in the conventional surgery group. (p=0.001). This difference was even stronger in the sub-group of very advanced stages (T3c+T4) (85.1% of TROMP group and in only 53.1% in the conventional surgery group, p=0.001). The duration of the primary cytoreductive surgery was about 33 minutes shorter in TROMP group (median 335 minutes vs 368 minutes; TROMP vs conventional, respectively) in spite of the fact that the most advanced cytoreductive procedures were performed statically significant more in TROMP operation arm in comparison with the conventional surgery arm. There was no statistically significant difference between the groups regarding the postoperative complication, blood loss or the length of stay in intensive care unit. CONCLUSION Total retroperitoneal en bloc resection of multivisceral-peritoneal packet (TROMP operation) is a feasible and very effective technique of surgical therapy in advanced ovarian cancer. This technique increased the complete tumor resection rate to 87.9% without increasing the blood loss, postoperative complications or the duration of surgery. A prospective randomized study is advised to validate these results. © IGCS and ESGO 2020. No commercial re-use. See rights and permissions. Published by BMJ.At present, there is no standard of care on the use of letrozole in ovarian cancer management. We performed a systematic review of the available literature addressing this issue. Data demonstrated a role for letrozole in ovarian cancer, in both the primary and recurrent setting. Letrozole, which has a favorable toxicity profile, seems to assure a prolonged recurrence-free interval, particularly when used as maintenance treatment, in low grade serous ovarian cancer; in recurrent cases it had also led to prolonged disease control. However, the optimal setting and biologically relevant patient population needs to be defined in larger trials. © IGCS and ESGO 2020. No commercial re-use. See rights and permissions.

METHODS Fluorescent biosensors were employed for an unbiased drug screen approach aiming at the identification of ICD enhancers. RESULTS Here, we discovered thiostrepton as an enhancer of ICD able to boost chemotherapy-induced ATP release, calreticulin exposure and high-mobility group box 1 exodus. Moreover, thiostrepton enhanced anticancer immune responses of oxaliplatin (OXA) in vivo in immunocompetent mice, yet failed to do so in immunodeficient animals. Consistently, thiostrepton combined with OXA altered the ratio of cytotoxic T lymphocytes to regulatory T cells, thus overcoming immunosuppression and reinstating anticancer immunosurveillance. CONCLUSION Altogether, these results indicate that thiostrepton can be advantageously combined with chemotherapy to enhance anticancer immunogenicity. © Author(s) (or their employer(s)) 2020.

However, in most of the clinical trials investigating immunotherapy in this subgroup, patients with symptomatic MBM and/or prior local brain radiotherapy were excluded. We studied the efficacy of nivolumab plus ipilimumab alone or in combination with local therapies regardless of treatment line in patients with asymptomatic and symptomatic MBM. METHODS Patients with MBM treated with nivolumab plus ipilimumab in 23 German Skin Cancer Centers between April 2015 and October 2018 were investigated. Overall survival (OS) was evaluated by Kaplan-Meier estimator and univariate and multivariate Cox proportional hazard analyses were performed to determine prognostic factors associated with OS. RESULTS Three hundred and eighty patients were included in this study and 31% had symptomatic MBM (60/193 with data available) at the time of start nivolumab plus ipilimumab. The median follow-up was 18 months and the 2 years anotherapy with nivolumab plus ipilimumab, particularly in combination with stereotactic radiosurgery or surgery improves OS in asymptomatic and symptomatic MBM. © Author(s) (or their employer(s)) 2020.

Published by BMJ.BACKGROUND Immune checkpoint inhibitors (ICIs) have expanded treatment options for metastatic renal cell carcinoma (mRCC); however, there are limited predictive biomarkers for response to ICIs in this indication, with programmed death-ligand 1 (PD-L1) status demonstrating little predictive utility in mRCC. While predictive of ICI response in other tumor types, the utility of tumor mutation burden (TMB) in mRCC is unclear. Here, we assess TMB, loss of antigen presentation genes and PD-L1 status correlated with outcomes to ICI treatment in mRCC. METHODS Tumor samples from 34 patients with mRCC treated with ICI therapy at Duke Cancer Institute were retrospectively evaluated using Personal Genome Diagnostics elio tissue complete (RUO version), a tumor genomic profiling assay for somatic variants, TMB, microsatellite status and genomic status of antigen presentation genes. Tumor samples were also analyzed with the Dako 28-8 PD-L1 immunohistochemistry assay. Deidentified clinical information was extracted from the medical record, and tumor response was evaluated based on the Response Evaluation Criteria In Solid Tumors (RECIST) V.
