Colorectal cancer (CRC) is the most common tumor type in both sexes combined in Western countries. Although screening programs, including the implementation of fecal occult blood test and colonoscopy, might reduce mortality by removing precursor lesions and making the diagnosis at an earlier stage. Unfortunately, ~25% to 40% will develop a tumor recurrence despite a curative operation. It is well-known that most recurrences occur within five years. There are a lot of solid guidelines for recurrence surveillance. We present a case of colon adenocarcinoma that underwent surgical resection of the descending colon with close recurrence surveillance follow-ups that showed normal carcinoembryonic antigen (CEA) for 12 years and then presented again with blood in stool and was found to have recurrent colon adenocarcinoma.

Purpose: Optimal management of retroperitoneal soft tissue sarcoma (RPS) often requires extensive tumor resections, frequently involving gastrointestinal organs. The impact of these procedures on the nutritional status and hemoglobin (Hb) levels of RPS patients remain unexplored. In this study, we aimed to evaluate preoperative nutritional status as well as the prevalence of anemia in RPS patients, and to investigate longitudinal changes throughout the disease course in order to identify potential strategies for prehabilitation.

Background: Cervical cancer poses a significant threat to women's health and encompasses various histological types, including squamous cell carcinoma (SCC), cervical adenocarcinoma (CA), and adenosquamous carcinoma. CA, in particular, presents a formidable challenge in clinical management due to its low early detection rate, pronounced aggressiveness, high recurrence rate, and mortality, compounded by the complexities associated with late-stage treatment. There is limited understanding of the similarities and differences in the pathogenesis mechanisms between CA and SCC, such as tumor heterogeneity and the tumor immune microenvironment (TME).

Background: PD-L1 expression in tumors and immune cells is a biomarker for the efficacy of anti-PD-1 antibody (APA) therapy across diverse cancers. Based on the results from the KEYNOTE-048 trial, pembrolizumab monotherapy is indicated for platinum-sensitive recurrent/metastatic head and neck squamous cell carcinoma (R/M-HNSCC) with a positive combined positive score (CPS). Conversely, nivolumab is utilized for platinum-pretreated R/M-HNSCC regardless of the positive tumor proportion score (TPS) following the results of the CheckMate-141; however, its subgroup analysis indicated that TPS-positive population tended to have a relatively high overall response rate and progression-free survival (PFS).

Hypertension

Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, MA (W.Z., D.H., M.A.M., Y.M.).
Background: Hypotensive episodes detected by 24-hour ambulatory blood pressure (BP) monitoring capture daily cumulative hypotensive stress and could be clinically relevant to cognitive impairment, but this relationship remains unclear.
Methods: We included participants from the Systolic Blood Pressure Intervention Trial (receiving intensive or standard BP treatment) who had 24-hour ambulatory BP monitoring measured near the 27-month visit and subsequent biannual cognitive assessments. We evaluated the associations of hypotensive episodes (defined as systolic BP drops of ≥20 mm Hg between 2 consecutive measurements that reached <100 mm Hg) and hypotensive duration (cumulative time of systolic BP <100 mm Hg) with subsequent cognitive function using adjusted linear mixed models.
