Herein, we investigated the pharmacokinetic (PK) profile of nedaplatin (cis-diamine-glycolateplatinum; CDGP) in a hemodialysis (HD) patient with advanced esophageal squamous cell carcinoma (ESCC) by administering the CDGP immediately prior to HD. Our patient was treated with CDGP (45 mg/m for a total dose of 60.2 mg) and 5-fluorouracil (560 mg/m for a total dose of 750 mg) before initiating HD. The total platinum (Pt) concentration (Pt) and free Pt concentration (Pt) 2 h after completion of HD were 0.4 μg/mL and 0.3 μg/mL, respectively. The removal rates of Pt and Pt by the dialyzer were 76.5% and 84.6%, respectively. Twenty-four hours after CDGP administration, the Pt was below the detection limit of the method of analysis. Pt within the range of the recommended CDGP target AUC was 8-10 μg/mL•h, the AUC of Pt and Pt were 16.5 μg/mL•h and 8.8 μg/mL•h, respectively. We conclude that HD should be performed after the end of CDGP infusion as part of the CDGP chemotherapy regimen for HD patients with ESCC, and suggest that HD is effective for obtaining a PK profile of CDGP similar to patients with normal renal function.

Background: Esophageal carcinoma (EC) presents a significant public health issue in China, with its prognosis impacted by myriad factors. The creation of a reliable prognostic model for the overall survival (OS) of EC patients promises to greatly advance the customization of treatment approaches.
Aim: To create a more systematic and practical model that incorporates clinically significant indicators to support decision-making in clinical settings.

Background: Esophageal cancer (EC) is one of the most common malignant tumors worldwide, which has severely threatened human health. This study aims to evaluate the prognostic factors and predictors of survival in patients diagnosed with advanced lower third esophageal carcinoma (aLEC). Based on the Surveillance, Epidemiology, and End Results (SEER) database, we developed a model (nomogram) to provide accurate and individualized survival prediction for the patients who have lost the opportunity to undergo radical surgery.

Acute esophageal necrosis (AEN) is an uncommon endoscopic finding characterized by a patchy or diffuse circumferential black pigmentation of the esophageal mucosa, corresponding to ischemic necrosis. It usually presents with upper gastrointestinal bleeding and is thought to be caused by a systemic low blood flow in patients with predisposing risk factors, like advanced age and cardiovascular comorbidities. After initial hemodynamic stabilization, diagnosis is established by esophagogastroduodenoscopy (EGD) with careful biopsies and histological evaluation.

Background: The RTOG 85-01 trial established that definitive concurrent chemoradiotherapy (CCRT) is the standard treatment for inoperable, locally advanced esophageal carcinoma, as well as for patients who decline surgery. The present study aims to compare the impact of three treatment modalities, CCRT, induction chemotherapy (ICT) followed by CCRT (ICT + CCRT), and CCRT followed by consolidation chemotherapy (CCT) (CCRT + CCT), on the survival of patients with inoperable esophageal squamous cell carcinoma (ESCC).
Methods: This retrospective analysis was conducted with 391 patients with ESCC who underwent radical CCRT with induction or CCT or CCRT only from January 2016 to October 2020 at the Fourth Hospital of Hebei Medical University in Shijiazhuang, Hebei province, China.
