Fecal, duodenal, and tumor microbiota composition of esophageal carcinoma patients, a longitudinal prospective cohort.

Background: The microbiome has been associated with chemotherapy and immune checkpoint inhibitor efficacy. How this pertains to resectable esophageal carcinoma is unknown. Our aim was to identify microbial signatures in resectable esophageal carcinoma associated with response to neoadjuvant chemoradiotherapy with or without an immune checkpoint inhibitor.

Impact of Short-Course Palliative Radiation Therapy on Pancreatic Cancer-Related Pain: Prospective Phase 2 Nonrandomized PAINPANC Trial.

Purpose: Clinical evidence is limited regarding palliative radiation therapy for relieving pancreatic cancer-related pain. We prospectively investigated pain response after short-course palliative radiation therapy in patients with moderate-to-severe pancreatic cancer-related pain.

Methods And Materials: In this prospective phase 2 single center nonrandomized trial, 30 patients with moderate-to-severe pain (5-10, on a 0-10 scale) of pancreatic cancer refractory to pain medication, were treated with a short-course palliative radiation therapy; 24 Gy in 3 weekly fractions (2015-2018).

Cryoballoon ablation as salvage therapy after nonradical resection of a high-risk T1b esophageal adenocarcinoma: a case report.

Although esophagectomy with or without (neo)adjuvant chemoradiation therapy is the current standard of care for patients with early esophageal adenocarcinoma with high-risk features or after nonradical endoscopic resection of an early esophageal adenocarcinoma, not all patients are eligible for surgery due to varying reasons. In these patients, cryoballoon ablation may serve as an alternative treatment option considering the potential of deeper tissue ablation as compared to heat-based ablation techniques. We report the first case in which cryoballoon ablation was successfully performed as salvage therapy with a curative intent for positive deep resection margins after an incomplete endoscopic resection of a recurrent early esophageal adenocarcinoma.

Considerable interobserver variation in delineation of pancreatic cancer on 3DCT and 4DCT: a multi-institutional study.

Background: The delineation of pancreatic tumors on CT is challenging. In this study, we quantified the interobserver variation for pancreatic tumor delineation on 3DCT as well as on 4DCT.

Methods: Eight observers (radiation oncologists) from six institutions delineated pancreatic tumors of four patients with (borderline) resectable pancreatic cancer.

A delayed traumatic right diaphragmatic hernia with hepatothorax.

A traumatic right diaphragmatic rupture is an uncommon condition, as it occurs in 0.8-3.6% after blunt trauma.
