Comparable long-term survival outcomes after endoscopic and gastrectomy treatment of pT1acN0M0 gastric adenocarcinoma in patients who met the expanded criteria.

Background: Whether the Western pT1acN0M0 gastric cancer (GC) patients who met the Japanese expanded criteria could be the candidates for endoscopic treatment (ET) remains unclear because of unknown long-term survival outcomes.

Methods: A retrospective cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) program was performed. The survival differences between pT1acN0M0 gastric adenocarcinoma patients who received ET or gastrectomy treatment (GT) were evaluated using multivariate survival analysis.

Application of two-sample Mendelian randomization method to assess the causal relationship between rheumatoid arthritis and osteoporotic fracture.

Background: The association between rheumatoid arthritis (RA) and osteoporotic fracture has garnered considerable attention; however, the causal relationships between diseases remain uncertain. Therefore, this study employed Mendelian randomization (MR) analysis to investigate the causal effects of RA on osteoporotic fracture.

Methods: The summary data for RA and osteoporotic fracture were extracted from the genome-wide association studies (GWAS) catalog and the Finn Biobank database.

Comparable long-term outcomes after endoscopic therapy and gastrectomy of early adenocarcinoma of esophagogastric junction: a population-based study.

Background And Aims: Current guidelines recommend consideration of endoscopic therapy (ET) when treating selected early gastric cancers. However, clinical decision-making on ET versus gastrectomy for early adenocarcinoma of esophagogastric junction (AEGJ) remains challenging because of uncertain long-term outcomes.

Methods: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results database from 2004 to 2017 of early AEGJ patients underwent ET or gastrectomy.

Impact of Lymph Nodes Examined on Survival in ypN0 Gastric Cancer Patients: a Population-Based Study.

Background: Our aim was to evaluate the prognostic value of the number of lymph nodes examined (eLNs) on survival in ypN0 gastric cancer (GC) patients, and further to define the optimal number of lymph nodes needed to be examined during radical gastrectomy of ypN0 GC patients.

Methods: A total of 1127 ypN0 GC patients during 2004-2015 from the Surveillance, Epidemiology, and End Results (SEER) database were included. The number of eLNs cutoff points that determined the greatest actuarial survival difference was calculated by the X-tile program.

Influence of Tumor Location on Lymph Node Metastasis and Survival for Early Gastric Cancer: a Population-Based Study.

Background: The question that whether the criteria for endoscopic resection of early gastric non-cardia cancer (GNCC) is appropriate for early gastric cardia cancer (GCC) remains unclear. Thus, our aim was to evaluate the influence of tumor location on lymph node metastasis (LNM) and overall survival (OS) for early gastric cancer (GC).

Methods: A total of 5440 early GC patients in the Surveillance, Epidemiology, and End Results (SEER) database were identified.

Principles of hatchet-skin flap for repair of tissue defects on the cheek.

Background: To date, cheek reconstruction remains a challenge for plastic surgeons. This report presents the authors' cheek reconstruction technique with different types of hatchet-skin flaps, which provides satisfactory results.

Methods: The cheek area was divided into three parts (P1, P2, and P3), with vertical lines passing through the medial and lateral canthus.
