Prognostic factors associated with 18FDG-PET/CT in esophageal squamous cell carcinoma after trimodality treatment.

PURPOSE: This study aimed to determine the pathological complete response (pCR), overall survival (OS), and disease-free survival (DFS) in patients with locally advanced esophageal squamous cell carcinoma (ESCC) using post-neoadjuvant chemoradiotherapy (nCRT) F-18-fluorodeoxyglucose (18FDG). METHODS: This is a retrospective study of patients with locally advanced ESCC receiving nCRT and then esophagectomy between January 2011 and December 2018 in the Tri-Service General Hospital, Taipei, Taiwan. A total of 50 patients were enrolled in the study. Survival analysis was performed using the Kaplan-Meier method and Cox proportional hazards model. Univariate and multivariate analysis were used to determine the independent prognostic factors. RESULTS: Fifty patients were enrolled in the study, and 18 had pathological complete response. Post-nCRT SUVmax ≥ 3 is a poor prognostic factor associated with overall survival (HR: 3.665, P = 0.013) and disease-free survival (HR: 3.417, P = 0.011). Poor prognosis was found in the non-pCR plus post-nCRT SUVmax ≥ 3 group compared with pCR plus post-nCRT SUVmax < 3 group. CONCLUSIONS: SUVmax ≥ 3 is a poor prognostic factor in esophageal squamous cell carcinoma after trimodality treatment, even in patients having pathological complete response.

Schwannoma of the Intercostal Nerve Manifesting as Chest Pain.

Many different benign and malignant tumors develop in the chest wall and pose a diagnostic and therapeutic challenge to clinicians. Chest wall schwannomas of the intercostal nerve are rare. This report describes the clinical and imaging findings of a patient who presented with persistent and progressive chest pain. The intercostal tumor was treated using wide excision with chest wall reconstruction and titanium plate fixation. Schwannoma was diagnosed on the basis of histopathologic examination.
