AI Article Synopsis
- Uterine serous carcinomas (USC) make up 10% of uterine cancers but cause 40% of related deaths, highlighting the need for better molecular profiling for treatment.
- A study of 53 USC patients analyzed genomic instability scores (GIS), tumor mutational burden (TMB), and tumor-infiltrating lymphocytes (TILs) to understand survival outcomes.
- Results indicated that a higher TMB correlates with improved survival rates, while the GIS did not show a similar association; increased TILs were related to higher GIS scores.
Article Abstract
Background: Uterine serous carcinomas represent 10% of uterine carcinomas but account for nearly 40% of deaths from the disease. Improved molecular characterization of these tumors is instrumental in guiding targeted treatment and improving outcomes. This study assessed the genomic instability score (GIS), tumor mutational burden (TMB), and tumor-infiltrating lymphocytes (TILs) in patients with USC. Methods: A retrospective cohort study evaluated patients with USC following staging surgery. The GIS and TMB were determined from archived specimens. We evaluated the tumoral expression of CD3, CD4, CD8, FOXP3, and CD68 using immunohistochemistry. T-tests were used to assess associations of TILs with the GIS. Results: We evaluated 53 patients with USC. The median GIS was 31 (range: 0−52) and a higher GIS was not associated with progression-free (PFS) or overall survival (OS). The median TMB was 1.35 mt/Mb; patients with TMB > 1.35 mt/Mb had improved PFS and OS (p = 0.005; p = 0.002, respectively). Tumors with increased CD3+ and CD4+ immune cells had a higher mean GIS (p = 0.013, p = 0.002). Conclusions: TMB > 1.35 mt/Mb was associated with improved survival in USC patients, whereas the GIS was not. Lower TMB thresholds may provide prognostic value for less immunogenic tumors such as USC. In this limited cohort, we observed that increased TIL populations were correlated with a higher GIS.

General Surgery, Aneurin Bevan University Health Board, Newport, GBR.
Aim: To assess recent colonoscopies and CT scans in conjunction with the feacal immunochemical test (FIT) for possibly downgrading urgent suspected cancer (USC) referrals.
Methods: A retrospective single-centre study was conducted, including all USC referrals for colonoscopy in 2022, excluding anal cancers. The CT and colonoscopy findings for a two-year period prior to the referral, along with the FIT result (if done), were noted.
Pleiotropic effects of mutant huntingtin on retinopathy in two mouse models of Huntington's disease.

Huntington's disease (HD) is caused by the expansion of a CAG repeat, encoding a string of glutamines (polyQ) in the first exon of the huntingtin gene (HTTex1). This mutant huntingtin protein (mHTT) with extended polyQ forms aggregates in cortical and striatal neurons, causing cell damage and death. The retina is part of the central nervous system (CNS), and visual deficits and structural abnormalities in the retina of HD patients have been observed.

Department of Neurological Surgery, Keck School of Medicine of the University of Southern California, Los Angeles, CA, USA.
Background: Aneurysmal subarachnoid hemorrhage (aSAH) carries a high economic cost and clinical morbidity in the United States. Beyond prolonged admissions and poor post-injury functional status, there is an additional cost of chronic shunt-dependent hydrocephalus for many aSAH patients. Adjuvant lumbar drain (LD) placement has been hypothesized to promote clearance of subarachnoid blood from the cisternal space, with an ultimate effect of decreasing shunt placement rates.
