An analysis of complex treatment of 154 patients with T2-4N0-2 stage rectal cancer is presented who were given preoperative chemoradiotherapy in regimen of dynamic functioning with total focal dose 39.5 Gy (71 patients of the first group) and 47 Gy (83 patients of the second group) using 5-fluororacil and cisplatin. A multivariant analysis has demonstrated a reliably increased frequency of total and close to total regressions of rectal cancer (1-2 stage by Mandard) in the second group as compared with reduced duration of the operative intervention the 1st group (43.2% and 23.9). Frequency of postoperative complications did not have reliable difference in both groups as well as the number of sphinctersaving surgical procedures.

Transperitoneal robot-assisted partial nephrectomy: a comparison of operative and oncological outcomes between posterior and anterolateral tumours.
Int Urol Nephrol
January 2025
Department of Urology, Zealand University Hospital, Roskilde, Denmark.
Objective: To compare operative and oncological outcomes, as well as the risk of postoperative complications in patients who underwent transperitoneal robot-assisted partial nephrectomy (RAPN) for renal tumours located either posteriorly or anterolaterally.
Methods: Retrospective, consecutive study including 451 patients who underwent transperitoneal RAPN for non-metastatic, localised renal tumours from May 2016 to April 2023. Operative data included duration of the procedure, warm ischaemia time, and blood loss; oncological data included surgical margins and recurrence; and 90-day postoperative complications were classified according to the Clavien-Dindo classification.
Tianxiangdan suppresses foam cell formation by enhancing lipophagy and reduces the progression of atherosclerosis.
In Vitro Cell Dev Biol Anim
January 2025
College of Traditional Chinese Medicine, Xinjiang Uygur Autonomous Region, Xinjiang Medical University, Urumqi, 830063, China.
The aim of this study is to assess the impact of Tianxiangdan (TXD) on lipophagy in foam cells and its underlying mechanism in treating atherosclerosis, particularly focusing on its efficacy in lowering blood lipids. In vivo, ApoE-/- atherosclerosis mouse models were established for group intervention. Blood lipid levels of the mice were measured, lipid deposition and autophagy levels in atherosclerotic plaques were assessed, and co-localization of lipid droplets and autophagosomes was examined.

Insights Imaging
January 2025
Department of Radiology, Peking University First Hospital, Beijing, 100034, China.
Objectives: To evaluate the performance of a 3D V-Net-based segmentation model of adrenal lesions in characterizing adrenal glands as normal or abnormal.
Methods: A total of 1086 CT image series with focal adrenal lesions were retrospectively collected, annotated, and used for the training of the adrenal lesion segmentation model. The dice similarity coefficient (DSC) of the test set was used to evaluate the segmentation performance.
Simultaneous integrated boost to lateral pelvic lymph nodes during chemoradiotherapy in high-risk rectal cancer.
Strahlenther Onkol
January 2025
Department of Radiation Oncology, University Hospital Tübingen, Hoppe-Seyler-Str. 3, 72076, Tübingen, Germany.
Background: Preoperative chemoradiotherapy combined with total mesorectal excision (TME) is a standard treatment for locally advanced rectal cancer (LARC). However, lateral pelvic lymph nodes (LPLNs) are often inadequately treated with standard regimens. This study examines the treatment and postoperative outcomes in LARC patients receiving a simultaneous integrated boost (SIB) for LPLNs during long-course chemoradiotherapy.

Dis Colon Rectum
November 2024
Department of Colon and Rectal Surgery, Memorial Sloan Kettering Cancer Center, New York.
Background: The watch-and-wait strategy provides an opportunity to pursue non-operative management in rectal cancer patients with clinical complete response after neoadjuvant therapy. The management of those with near complete response remains controversial.
Objective: We assessed the oncologic outcomes of patients managed by watch-and-wait versus total mesorectal excision according to clinical response to neoadjuvant therapy.
