Impact of Body Weight Loss During Preoperative Chemoradiotherapy on Prognosis of Patients With Lower Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
The present study aimed to investigate the relationship between changes in body weight and composition during chemoradiotherapy, such as the psoas muscle mass index, visceral fat index, and subcutaneous fat index obtained from computed tomography images, and long‐term outcomes in rectal cancer patients.

Enhancing prognostic accuracy in predicting rectal neuroendocrine neoplasms

World Journal of Gastroenterology
The recently published retrospective study introduces the GATIS score, a new predictive model for rectal neuroendocrine neoplasms. By analyzing data from a large Chinese multicenter cohort, the study shows that the GATIS score, incorporating tumor grade, T stage, tumor size, age, and prognostic nutritional index, demonstrates superior predictive power ...

Educational Impact of Artificial Intelligence‐Navigation Surgery on Anatomical Landmark Recognition in Medical Students

Annals of Gastroenterological Surgery, EarlyView.
This study evaluated the educational impact of artificial intelligence (AI)‐navigation surgery that provides real‐time anatomical landmark recognition during laparoscopic cholecystectomy for medical students. Thirty students were randomized into surgeon‐guided, self‐learning, and AI‐learning groups, and their performance was assessed using Dice ...

Impact of Two‐Team Surgery on Short‐ and Long‐Term Outcomes of Transanal Total Mesorectal Excision for Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
This study investigated the impact of two‐team surgery on short‐ and long‐term outcomes of transanal total mesorectal excision for rectal cancer. Two‐team surgery has some advantages over one‐team surgery, such as shorter operation time, decreased estimated blood loss, increased number of lymph nodes dissected, and decreased positive distal margin ...

Perioperative and Oncological Outcomes of Colorectal Cancer Surgery in Obese Patients: A Multicenter Retrospective Study

Annals of Gastroenterological Surgery, EarlyView.
The prognostic value of the log odds of positive lymph nodes (LODDS) across BMI categories was investigated in patients undergoing colorectal cancer resection. The exploratory evidence demonstrates that LODDS serves as a strong prognostic marker, and its adverse effect may be more pronounced in patients with higher BMI.

Prognostic Value of Psoas Major Muscle Volume in Assessing Sarcopenia in Elderly Patients With Rectal Cancer

Annals of Gastroenterological Surgery, EarlyView.
This study investigates the prognostic utility of a novel volumetric indicator—psoas volume index (PVI)—for assessing sarcopenia in elderly rectal cancer patients. Sarcopenia classified by our proposed PVI cut‐off values was associated with poor nutritional and inflammatory status, and patients with low PVI showed significantly worse long‐term outcomes.

Prognostic value of FBXW7 tumor suppressor gene expression and mutations in patients with colorectal cancer: A meta-analysis

Cancer Treatment and Research Communications
Background: Colorectal cancer (CRC) ranks as the second most common cause of cancer-related mortality globally. The tumor suppressor gene FBXW7 is considered to play a key role in determining patient prognosis.

Neuroendocrine Cancer of Rectum Metastasizing to Ovary

Case Reports in Oncological Medicine, 2016
Neuroendocrine carcinomas (NECs) are rare malignancies that originate from the hormone-producing cells of the body’s neuroendocrine system. Rectal high grade NEC (HG-NEC) constituting less than 1% of colorectal cancers can cause large ovarian metastasis ...
