Purpose: The Cancer Genome Atlas Research Network identified Epstein-Barr-Virus (EBV)-positive gastric cancer as a distinct molecular subtype. The prevalence is 8-9% and the histological examination shows pronounced lymphocytic infiltration, elevated levels of IFN-γ and consequently overexpression of PD-L1. The role of plasma EBV DNA load as a prognostic factor in patients with this cancer subtype is still to be defined. Methods and analysis: The present multicenter prospective observational study “EBV PRESAGE”, involving German and Italian cancer centers, aims to evaluate the prognostic role of plasma EBV DNA in EBV-related gastric cancer (GC). The objective is to study the association between plasma EBV DNA load at different consecutive time points and the patient’s prognosis. Every patient with a new diagnosis of gastric cancer (including gastroesophageal junction adenocarcinoma) will be screened for Epstein-Barr encoded small Region (EBER) on tissue biopsies using in situ hybridization (ISH). If EBER ISH is positive, blood analysis for plasma EBV DNA will be conducted. The plasma EBV quantitative analysis will be centralized, and extraction, detection, and quantification of EBV DNA in plasma samples will be performed using real-time PCR. Discussion: We hypothesized that plasma EBV DNA represents a non-invasive tool for monitoring EBV-related GC and might be valuable as a prognostic marker. [ABSTRACT FROM AUTHOR]

Objective: The study's aim was to determine to what extent total visceral adipose tissue (VAT) volume (VVAT‐T) measured from segmented VAT areas (AVAT) on all axial computed tomography (CT) sections (thickness of 5 mm) between the diaphragm and pelvic floor can be predicted by the AVAT of commonly selected landmark sections in patients with overweight or obesity. Methods: A total of 113 patients (31 females, 82 males) with images of full abdominopelvic coverage and proper image quality were included (BMI = 25.0‐64.1 kg/m2, 29.5 ± 4.9 kg/m2). Linear regression between AVAT and VVAT‐T (reference) was used to determine approximate equations for VAT volume for all parameters (single sex, different anatomical landmarks or lumbar intervertebral disc spaces, one or five axial sections). Agreement was evaluated by the multivariate coefficient of determination and by the SD of the percentage difference (sd%) between the estimated VAT volume on one or five sections and VVAT‐T. Results: The VVAT‐T was 0.9 to 8.4 (3.8 ± 2.2) L for females and 2.7 to 11.7 (5.6 ± 2.1) L for males. Best agreement was found at L2‐3 (sd% = 14.3%‐15.5%) for females and at L1‐2 or L2‐3 (11.7%‐12.4%) for males. Agreement at the umbilicus or the femoral heads was poor (20.2%‐57.9%). Segmentation of one or five sections was substantially faster (11/70 seconds) than whole‐abdomen processing (15 minutes). Conclusions: VVAT‐T can be rapidly estimated by VAT segmentation of axial CT sections at sex‐specific lumbar intervertebral disc spaces. [ABSTRACT FROM AUTHOR]

Background: Body fat and/or muscle composition influences prognosis in several cancer types. For advanced gastric and gastroesophageal junction cancer, we investigated which body composition parameters carry prognostic information beyond well‐established clinical parameters using robust model selection strategy such that parameters identified can be expected to generalize and to be reproducible beyond our particular data set. Then we modelled how differences in these parameters translate into survival outcomes. Methods: Fat and muscle parameters were measured on baseline computed tomography scans in 761 patients with advanced gastric or gastroesophageal junction cancer from the phase III EXPAND trial, undergoing first‐line chemotherapy. Cox regression analysis for overall survival (OS) and progression‐free survival (PFS) included body composition parameters and clinical prognostic factors. All continuous variables were entered linearly into the model as there was no evidence of non‐linear prognostic impact. For transferability, the final model included only parameters that were picked by Bayesian information criterion model selection followed by bootstrap analysis to identify the most robust model. Results: Muscle and fat parameters formed correlation clusters without relevant between‐cluster correlation. Mean muscle attenuation (MA) clusters with the fat parameters. In multivariate analysis, MA was prognostic for OS (P < 0.0001) but not for PFS, while skeletal muscle index was prognostic for PFS (P = 0.02) but not for OS. Worse performance status Eastern Cooperative Oncology Group (ECOG 1/0), younger age (on a linear scale), and the number of metastatic sites were strong negative clinical prognostic factors for both OS and PFS. MA remained in the model for OS (P = 0.0001) following Bayesian information criterion model selection in contrast to skeletal muscle index that remained prognostic for PFS (P = 0.009). Applying stricter criteria for transferability, MA represented the only prognostic body composition parameter for OS, selected in >80% of bootstrap replicates. Finally, Cox model‐derived survival curves indicated that large differences in MA translate into only moderate differences in expected OS in this cohort. Conclusions: Among body composition parameters, only MA has robust prognostic impact for OS. Data suggest that treatment approaches targeting muscle quality are unlikely to prolong OS noticeably on their own in advanced gastric cancer patients, indicating that multimodal approaches should be pursued in the future.

Introduction: The phase 2 RAMONA study demonstrated that second-line nivolumab ± ipilimumab immunotherapy was feasible and effective in older patients with advanced esophageal squamous cell cancer (ESCC). Here, we presented results from functional status (FS) and quality-of-life (QoL) analyses., Materials and Methods: Patients aged ≥65 years with advanced ESCC and disease progression following first-line therapy were enrolled for study treatment with nivolumab ± ipilimumab. Geriatric assessments (GA) consisting of G8 and GoGo/SlowGo evaluation, and quality of life (QoL) assessments with EORTC QLQ-C30 questionnaires were conducted at baseline and during the treatment. A post hoc analysis was performed to compare therapy efficacy, toxicity, and QoL between age groups (≥70 years vs. <70 years) and functionality groups (G8 > 14 vs. ≤14 and GoGo vs. SlowGo)., Results: In 66 treated patients with a median age of 70.5 years, older patients had non-inferior overall survival and tumor response compared to younger patients, with no increased treatment-related adverse events. Fitter patients (G8 > 14, GoGo) had a clinically, yet not statistically significant, survival advantage than less fit patients (G8 ≤ 14, SlowGo) patients. Moreover, FS by G8 and GoGo/SlowGo significantly correlated with QoL. Overall, QoL was impaired at baseline but remained stable in all scales over the course of immunotherapy., Discussion: The administration of nivolumab ± ipilimumab second-line immunotherapy in older patients with ESCC did not show age-dependent effects and maintained QoL. GA could identify functional deficits and limitations of QoL and should be implemented in the context of immunotherapy., Clinicaltrials: gov: NCT03416244., Competing Interests: Declaration of Competing Interest NMB reports research funding and receipt of equipment from Deutsche Forschungsgemeinschaft.
