Early detection of colorectal cancer (CRC) is key for prevention and the ability to impact long-term survival of CRC patients. However, the compliance rate of recommended colonoscopy for the population aged from 50 to 75 years is only 50-75 % in the US. A highly sensitive and specific non-invasive test is needed to enhance CRC management. As for late-stage patients, a non-invasive prognostic biomarker is also critical for improving patient treatment protocols. The discovery that non-coding microRNAs (miRNAs) are stable in body fluids such as plasma, serum and exosomes presents the opportunity to develop novel strategies, taking advantage of circulating miRNAs as early diagnostic biomarkers of CRC. The goal of using circulating miRNA-based prognostic biomarkers for CRC patients has been pursued extensively. In this review, we will try to cover the major recent advancements at the frontier of this research area.

Introduction: Right-sided colon cancer is a prevalent malignancy. The standard surgical treatment for this condition is laparoscopic right hemicolectomy, with ileocolic anastomosis being a crucial step in the procedure. Recently, intracorporeal ileocolic anastomosis has garnered attention for its minimally invasive benefits.

Department of Surgery, Papageorgiou General Hospital, Thessaloniki, Greece.
Background: We performed a systematic review and network meta-analysis (NMA) of individualized patient data (IPD) to inform the development of evidence-informed clinical practice recommendations.
Methods: We searched MEDLINE, Embase, and Cochrane Central in October 2023 to identify RCTs comparing Hartmann's resection (HR), primary resection and anastomosis (PRA), or laparoscopic peritoneal lavage (LPL) among patients with class Ib-IV Hinchey diverticulitis. Outcomes of interest were prioritized by an international, multidisciplinary panel including two patient partners.
Prognostic value of pseudotime from texture parameters of FDG PET/CT in locally advanced rectal cancer with neoadjuvant concurrent chemoradiotherapy.
Sci Rep

Department of Nuclear Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-Ro, Gangnam-Gu, Seoul, 06351, Republic of Korea.
Texture analysis generates image parameters from F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Although some parameters correlate with tumor biology and clinical attributes, their types and implications can be complex. To overcome this limitation, pseudotime analysis was applied to texture parameters to estimate changes in individual sample characteristics, and the prognostic significance of the estimated pseudotime of primary tumors was evaluated.

Department of Radiology, the Affiliated Taian City Central Hospital of Qingdao University, Tai'an, 271099, China.
This study aimed to investigate the correlation between baseline MRI features and baseline carcinoembryonic antigen (CEA) expression status in rectal cancer patients. A training cohort of 168 rectal cancer patients from Center 1 and an external validation cohort of 75 rectal cancer patients from Center 2 were collected. A nomogram was constructed based on the training cohort and validated using the external validation cohort to predict high baseline CEA expression in rectal cancer patients.
