Background: Currently, optimal treatment strategy for resectable primary small cell carcinoma of the esophagus (PSmCCE) remains controversial. To address this, we conducted a multicenter study to evaluate treatment patterns and long-term survival of PSmCCE patients who underwent radical resection.

Methods: This retrospective multicenter study included resected PSmCCE patients who received radical resection at seven high-volume cancer centers.

The goal of this study was to compare the advantages of conventional laparoscopic surgery (CLS) and the split-leg supine position single-port plus one laparoscopic surgery (SSP SILS + 1) in esophageal surgery. This study enrolled 73 patients who previously underwent radical esophagectomy for esophageal cancer from August 2021 to February 2023. Among them, 36 patients underwent SSP SILS + 1, whereas the remaining 37 patients underwentCLS.

Article Synopsis
  • The study examines the effectiveness and safety of neoadjuvant immunochemotherapy (NAIC) using toripalimab compared to traditional neoadjuvant chemotherapy (NAC) in treating locally advanced esophageal squamous cell carcinoma (ESCC).
  • Conducted as a phase III clinical trial in China, 252 patients were randomly assigned to receive either NAIC (toripalimab + chemotherapy) or NAC alone, with primary focus on event-free survival and secondary outcomes like overall survival and pathological response.
  • Results showed a significant improvement in event-free survival (77.9% vs. 64.3%) and overall survival (94.1% vs. 83.0%) for the toripalimab group

Background: To date, few studies have compared effectiveness and survival rates of neoadjuvant chemotherapy combined with immunotherapy (NACI) and conventional neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced esophageal squamous cell carcinoma (ESCC). The present study was conducted to compare therapeutic response and survival between NACI and NCRT.

Methods: The study cohort comprised patients with locally advanced ESCC treated with either NACI or NCRT followed by surgery between June 2018 and March 2021.

Peripheral membrane proteins can adopt distinct orientations on the surfaces of lipid bilayers that are often short-lived and challenging to characterize by conventional experimental methods. Here we describe a robust approach for mapping protein orientational landscapes through quantitative interpretation of paramagnetic relaxation enhancement (PRE) data arising from membrane mimetics with spin-labeled lipids. Theoretical analysis, followed by experimental verification, reveals insights into the distinct properties of the PRE observables that are generally distorted in the case of stably membrane-anchored proteins.

Recent advances in direct inhibition of Ras benefit from the protein's intrinsic dynamic nature that derives therapeutically vulnerable conformers bearing transiently formed cryptic pockets. Hotspot mutants of Ras are major tumor drivers and are hyperactivated in cells at variable levels, which may require allele-specific strategies for effective targeting. However, it remains unclear how the prevalent oncogenic mutations and activation states perturb the free energy landscape governing the protein dynamics and druggability.

Background: Currently, the role of immunotherapy in neoadjuvant setting for patients with locally advanced esophageal squamous cell carcinoma (ESCC) is gradually attracting attention. Few studies compared the efficacy of neoadjuvant immunochemotherapy (NICT) and neoadjuvant chemoradiotherapy (NCRT). Our study aimed to compare treatment response and postoperative complications after NICT followed by surgery with that after conventional NCRT in patients with locally advanced ESCC.

Objectives: The latest version of the National Comprehensive Cancer Network recommends neoadjuvant therapy followed by surgical treatment or radical chemoradiotherapy for patients with cT3N0M0. Neoadjuvant therapy can improve the prognosis of patients with locally advanced esophageal cancer. Therefore, the evaluation or prediction of T stage is particularly important because the treatment could differently affect the prognosis.

Background: Postoperative pneumonia (PP) is the most common pulmonary complication of esophagectomy. It is of great importance to identify any high-risk factors and prevent pulmonary complications to improve the prognosis of patients with esophageal cancer undergoing esophagectomy. Thus, we established a predictive model of PP in patients with neoadjuvant immunochemotherapy for resectable esophageal squamous cell carcinoma (ESCC), and provide suggestions for the best strategy for the perioperative period of the patients.

Background: Multiple clinical trials were conducted to evaluate the efficacy of neoadjuvant therapy in esophageal cancer but exhibited mixed results, indicating that the efficacy of neoadjuvant therapy remains controversial in the treatment of esophageal cancer. Our study was conducted to investigate the value of neoadjuvant therapy in patients with esophageal cancer with supraclavicular lymph node metastases.

Methods: We retrospectively enrolled 231 patients who had resectable esophageal squamous cell carcinoma (ESCC) with supraclavicular lymph node metastases from June 2008 to November 2018.

Background: Numerous retrospective studies have reported that sublobectomy has a poorer prognosis than lobectomy in patients with early-stage lung cancer. The purpose of this study was to determine whether adjuvant treatment could improve the prognosis of patients with non-small cell lung cancer (NSCLC) ≤3 cm after sublobectomy.

Methods: We collected data from 17,763 patients with T1N0M0 NSCLC after surgery from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015.

Background: This study explores whether postoperative hand-assisted expectoration can reduce postoperative pulmonary complications (PPCs) in patients with esophageal cancer.

Methods: A retrospective analysis was performed on 543 patients undergoing radical esophageal cancer (EC) surgery in our hospital from October 2018 to August 2019, 156 of whom received postoperative handassisted sputum excretion (pulmonary rehabilitation, PR) and 387 of whom who did not receive postoperative hand-assisted sputum excretion (no pulmonary rehabilitation, NPR). Because the clinical characteristics of the two groups were not balanced, we used propensity score matching (PSM) to account for the variable factors of age, gender, body mass index (BMI), chronic respiratory comorbidity, smoking index, operation time, operation method, pathological stage.
