Association of post-treatment longitudinal symptom severity clusters with subsequent survival in oropharyngeal cancer.

Background: Patients with cancer often experience multiple symptoms concurrently. We identified patient clusters based on longitudinal symptom severity trajectories in oropharyngeal cancer (OPC) and evaluated the potential clinical utility of this approach.

Methods: A retrospective OPC patient cluster analysis using 6 months of symptom severity data from radiotherapy initiation.

Endoscopic resection with adjuvant treatment versus esophagectomy for early-stage esophageal cancer.

Objective: To evaluate the outcome following the strategy of endoscopic R0 resection (ER) plus adjuvant treatment (AT) versus esophagectomy for esophageal squamous cell cancer in T1a invading muscularis mucosa (M3)-T1b stage.

Methods: We evaluated the outcomes of 46 esophageal squamous cell cancer (ESCC) patients with T1aM3-T1b stage who underwent ER + AT from the Esophageal Cancer Endoscopic Therapy Consortium (ECETC) and compared these outcomes to 92 patients who underwent esophagectomy. Propensity score matching (1:2) was used, with overall survival (OS) and relapse-free survival (RFS) being compared between the two groups.
