Role of CT texture analysis for predicting peritoneal metastases in patients with gastric cancer.

Purpose: Aim of the study was to perform CT texture analysis in patients with gastric cancer (GC) to investigate potential role of radiomics for predicting the occurrence of peritoneal metastases (PM).

Materials And Methods: In this single-centre retrospective study, patients with gastric adenocarcinoma and surgically confirmed presence or absence of PM were, respectively, enrolled in group PM and group non-PM. Patients with T1-staging, previous treatment or presence of imaging artifacts were excluded from the study.

Quality of life in non-early rectal cancer treated by neoadjuvant radio-chemotherapy and endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgery (TEM) versus laparoscopic total mesorectal excision.

Background: In selected patients with N0 rectal cancer, endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgery (TEM) may be an alternative treatment option to laparoscopic total mesorectal excision (LTME). Aim of this study is to evaluate the short- and medium-term quality of life (QoL) from a retrospective analysis of prospectively collected data in patients with iT2-iT3 N0-N+ rectal cancer, who underwent ELRR by TEM or LTME after neoadjuvant radio-chemotherapy (n-RCT).

Methods: Thirty patients with iT2-iT3 rectal cancer who underwent ELRR by TEM (n = 15) or LTME (n = 15) were enrolled in this study.
