Background: Among patients not undergoing curative-intent therapy for esophagogastric cancer, access to care may vary. We examined the geographic distribution of care delivery and survival and their relationship with distance to cancer centres for non-curative esophagogastric cancer, hypothesising that patients living further from cancer centres have worse outcomes.
Methods: We conducted a population-based analysis of adults with non-curative esophagogastric cancer from 2005 to 2017 using linked administrative healthcare datasets in Ontario, Canada. Outcomes were medical oncology consultation, receipt of chemotherapy, and overall survival. Using geographic information system analysis, we mapped locations of cancer centres and outcomes across census divisions. Bivariate choropleth maps identified regional outcome discordances. Multivariable regression models assessed the relationship between distance from patient residence to the nearest cancer centre and outcomes, adjusting for demographic, clinical, and socioeconomic factors.
Results: Of 10,228 patients surviving a median 5.1 months (IQR: 2.0-12.0), 68.5% had medical oncology consultation and 32.2% received chemotherapy. Certain distances (reference ≤ 10 km) were associated with lower consultation [relative risk 0.79 (95% CI 0.63-0.97) for ≥ 101 km], chemotherapy receipt [relative risk 0.67 (95% CI 0.53-0.85) for ≥ 101 km], and overall survival [hazard ratio 1.07 (95% CI 1.02-1.13) for 11-50 km, hazard ratio 1.13 (95% CI 1.04-1.23) for 51-100 km].
Conclusion: A third of patients did not see medical oncology and most did not receive chemotherapy. Outcomes exhibited high geographic variability. Location of residence influenced outcomes, with inferior outcomes at certain distances > 10 km from cancer centres. These findings are important for designing interventions to reduce access disparities for non-curative esophagogastric cancer care.

Background: Disease-related malnutrition (DRM) and sarcopenia are prevalent conditions in gastrointestinal cancer patients, whose early diagnosis is essential to establish a nutritional treatment that contributes to optimizing adverse outcomes and improving prognosis. Phase angle (PhA) and rectus femoris ultrasound measurements are considered effort-independent markers of muscle wasting, which remains unrecognized in oncology patients.
Objective: This study aimed to evaluate the potential utility of PhA, rectus femoris cross-sectional area (RFCSA), and rectus femoris thickness (RF-Y-axis) in predicting malnutrition and sarcopenia in patients with esophagogastric cancer (EGC).

Background: The inclusion of clinical frailty in the assessment of patients planned for major surgery has proven to be an independent predictor of outcome. Since approximately half of all patients in the UK diagnosed with oesophagogastric (OG) cancer are over 75 years of age, assessment of frailty may be important in selection for surgery.
Materials And Methods: This retrospective cohort study applied the Hospital Frailty Risk Score to data obtained from the NHS Secondary Uses Service electronic database for patients aged 75 years or older undergoing oesophagectomy and gastrectomy between April 2017 and March 2020.
To explore whether ultra-sensitive circulating tumor DNA (ctDNA) profiling enables early prediction of treatment response and early detection of disease progression, we applied NeXT Personal, an ultra-sensitive bespoke tumor-informed liquid biopsy platform, to profile tumor samples from the KeyLargo study, a phase II trial in which metastatic esophagogastric cancer (mEGC) patients received capecitabine, oxaliplatin, and pembrolizumab. All 25 patients evaluated were ctDNA-positive at baseline. Minimal residual disease (MRD) events varied from 406,067 down to 1.
