Introduction: It is an accepted fact that the local recurrence rate can be decreased up to 50% for the metastatic rectum tumours irradiated only preoperatively.
Materials And Methods: 181 patients having rectum tumour were irradiated preoperatively with 36 or 40 Gy between 1990 and 2001. The classification was made according to the modified Astler-Coller pathological staging system. The radiation treatment was carried out with telecobalt unit or high energy photon of linear accelerator after computerized radiation treatment planning.
Results: The most important characterizing factor for the efficiency of the preoperative irradiation is the local recurrence rate that was found to be 21.56% in our investigation. The survival rate was significantly influenced by the age of the patient and the applied dose.
Conclusion: Our statistical analysis was applied to investigate the efficiency of the only preoperatively irradiated patients. The results are in agreement with the reported contributions.

Enhanced O-glycosylation Site Prediction Using Explainable Machine Learning Technique with Spatial Local Environment.
Bioinformatics
January 2025
Department of Chemical Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, United States.
Motivation: The accurate prediction of O-GlcNAcylation sites is crucial for understanding disease mechanisms and developing effective treatments. Previous machine learning models primarily relied on primary or secondary protein structural and related properties, which have limitations in capturing the spatial interactions of neighboring amino acids. This study introduces local environmental features as a novel approach that incorporates three-dimensional spatial information, significantly improving model performance by considering the spatial context around the target site.

Objective: We evaluated the accuracy of oncologists' estimates of expected survival time in recurrent ovarian cancer.
Methods: Oncologists estimated expected survival time at baseline for each patient, who were then followed up for survival time. We hypothesized that oncologists' estimates of expected survival time would be independently significant predictors of survival, unbiased (approximately equal proportions [50%] living longer versus shorter than their expected survival time), or imprecise (<30% within 0.

Objective: We sought to determine the safety and efficacy of the oral progesterone antagonist onapristone in combination with anastrozole in patients with recurrent progesterone receptor-positive adult-type granulosa cell tumor of the ovary.
Methods: This was a single-institution phase II study of patients with progesterone receptor-positive adult-type granulosa cell tumor who received at least 1 prior line of chemotherapy. Patients were enrolled from November 2021 to August 2022 and tissue was evaluated for progesterone receptor status via immunohistochemistry.
Comparison of the efficacy of neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy in locally advanced rectal cancer patients: meta-analysis of randomized controlled trials.
Int J Surg

Department of Gastrointestinal Surgery, Clinical Medical College and The First Affiliated Hospital of Chengdu Medical College, Chengdu 610500, Sichuan Province, China.
Background: Preoperative neoadjuvant chemoradiotherapy (nCRT) is considered to be the standard treatment strategy for locally advanced rectal cancer (LARC); however, the risk of adverse events and postoperative recurrence remains significant. This study aimed to evaluate the non-inferiority of neoadjuvant chemotherapy (nCT) compared with nCRT in patients with LARC and to assess the possibility of eliminating radiotherapy on the basis of guaranteed efficacy.
Materials And Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify randomized controlled trials (RCTs) comparing the efficacy of nCRT and nCT for LARC.
Treatment of Cutaneous Adnexal Carcinoma With Radiotherapy: A 20-Year, Single-Institution Experience in 49 Patients.
Am J Clin Oncol

Department of Radiation Oncology, Memorial Sloan Kettering Cancer Center, New York, NY.
Objectives: Cutaneous adnexal carcinomas (CACs) are rare skin cancers with no established treatment guidelines. Given the limited data, this study aims to explore the characteristics and outcomes of patients with CAC treated with radiation therapy (RT).
Methods: Patients diagnosed with CAC between 2000 and 2020 who received RT were included.
