Machine learning model predicting factors for incisional infection following right hemicolectomy for colon cancer.

Background And Aim: Colorectal cancer is a prevalent malignancy worldwide, and right hemicolectomy is a common surgical procedure for its treatment. However, postoperative incisional infections remain a significant complication, leading to prolonged hospital stays, increased healthcare costs, and patient discomfort. Therefore, this study aims to utilize machine learning models, including random forest, support vector machine, deep learning models, and traditional logistic regression, to predict factors associated with incisional infection following right hemicolectomy for colon cancer.

EEF1D stabilized by SRSF9 promotes colorectal cancer via enhancing the proliferation and metastasis.

Colorectal cancer (CRC) is the third most common cancer and causes high mortality worldwide. Although CRC has been studied widely, the molecular mechanism is not completely known. Eukaryotic translation elongation factor 1 delta (EEF1D) participates in the progression of various tumors, however, the effect of EEF1D on CRC remains unclear.

Cancer spreading patterns based on epithelial-mesenchymal plasticity.

Metastasis is a major cause of cancer-related deaths, underscoring the necessity to discern the rules and patterns of cancer cell spreading. Epithelial-mesenchymal plasticity contributes to cancer aggressiveness and metastasis. Despite establishing key determinants of cancer aggressiveness and metastatic ability, a comprehensive understanding of the underlying mechanism is unknown.

Modular Pelvic Exenteration for Advanced Rectal Cancer in Frozen Pelvis.

BACKGROUND Surgery for locally advanced rectal cancer with frozen pelvis is challenging. Therefore, we designed the "modular pelvic exenteration" surgical strategy to achieve better radical resection. CASE REPORT A 51-year-old man with rectal cancer refused surgery and received chemotherapy and radiotherapy.

A "conversion-deterioration-double mutation" theory for the evolution and progression of colorectal cancer.

In this study, based on some clinical phenomena and recently published knowledge, we proposed our "conversion-deterioration-double mutation" theory, which provides a possible unifying explanation for the evolutionary process of colorectal cancer cells in the human body. In this theory, we proposed that there is a partial interconversion and a jump conversion relationship among normal colorectal epithelial cells, colorectal cancer cells, stem cells, and cancer stem cells (conversion). This conversion leads to tumor heterogeneity.

Reconsideration of recurrence and metastasis in colorectal cancer.

To discuss recurrence patterns and their significance in colorectal cancer. Preexisting medical hypotheses and the clinical phenomena of recurrence in colorectal cancer were evaluated and integrated. Colorectal cancer recurrence/metastasis consists of two types: recurrence from the activation of dormant cancer cells and recurrence from postoperative residual cancer cells.

Knockdown of SFRS9 Inhibits Progression of Colorectal Cancer Through Triggering Ferroptosis Mediated by GPX4 Reduction.

Ferroptosis, a newly discovered form of programmed cell death characterized by lipid peroxidation, crafts a new perspective on cancer treatment. Serine and arginine rich splicing factor 9 (SFRS9) is frequently described as a proto-oncogene in cervical and bladder cancer. However, the role of SFRS9 in colorectal cancer (CRC) and whether SFRS9 exerts its function associated with ferroptosis is largely unknown.

Excising the neovagina due to introital atresia and closed neovaginal loop after sigmoid vaginoplasty: A case report.

Introduction: Vaginal agenesis is a congenital disorder, which can be managed by nonsurgical dilation or surgical reconstruction of the vagina. The sigmoid vaginoplasty procedure is a popular approach, which pulls down part of the sigmoid colon to form a neovagina. One complication of this procedure is introital stenosis.

Inhibition of SRSF9 enhances the sensitivity of colorectal cancer to erastin-induced ferroptosis by reducing glutathione peroxidase 4 expression.

Ferroptosis, a newly iron-dependent form of cell death, is often accompanied by the damage of membrane lipid peroxide. Recently, the ferroptosis inducer erastin has been reported to exhibit potential anti-cancer activities. The aim of this study was to investigate the effects of SRSF9 on the sensitivity of colorectal cancer (CRC) to erastin and explore the underlying molecular mechanism.

Treatment of slow transit constipation-induced ileus during pregnancy by colectomy with ileorectal anastomosis: A case report.

Introduction: Slow transit constipation is a major cause of chronic constipation. During pregnancy, changes in hormone levels and the physical effects of an enlarged uterus could cause new onset slow transit constipation or aggravate a pre-existing constipation. The management of slow transit constipation-induced ileus during pregnancy is a medical dilemma.

Rectal Mucinous Adenocarcinoma Invading Retrorectal Dermoid Cysts: A Case Report.

Rectal mucinous adenocarcinoma is a subtype of colorectal adenocarcinoma, which is more aggressive and prone to invade adjacent normal organs or tissues compared with non-mucinous adenocarcinoma. Retrorectal dermoid cyst is a rare congenital disease, which usually are benign but with a potential for malignant degeneration. In this article, we report a case which presented a rectal mucinous adenocarcinoma invading into retrorectal dermoid cysts, indicating that besides adjacent normal organs or tissues, malignancies can also invade adjacent tumors, making their diagnosis and management more complicated.

A novel cancer stem cell-based classification model for the tumorigenesis and development of colorectal cancer.

Cancer is a heterogenetic disease. Although multiple hypotheses and models have been indicated, there is still no robust method to distinguish the heterogeneity of cancer. Evidence has been provided showing that cancer stem cells (CSCs) play an important role in the origin and progression of cancer.

The function of BTG3 in colorectal cancer cells and its possible signaling pathway.

Purpose: B-cell translocation gene 3 (BTG3) has been identified as a candidate driver gene for various cancers, but its specific role in colorectal cancer (CRC) is poorly understood. We aimed to investigate the relationship between expression of BTG3 and clinicopathological features and prognosis, as well as to explore the effects and the role of a possible BTG3 molecular mechanism on aggressive colorectal cancer behavior.

Methods: BTG3 expression was assessed by immunohistochemistry (IHC) on specimens from 140 patients with CRC.

Naringenin induces laxative effects by upregulating the expression levels of c-Kit and SCF, as well as those of aquaporin 3 in mice with loperamide-induced constipation.

Constipation is a common affliction which causes discomfort and affects the quality of life of affected individuals. Naringenin (NAR), a natural flavonoid widely found in citrus fruits and tomatoes, has been reported to exhibit various pharmacological effects, such as anti-inflammatory, anti-atherogenic, anti-mutagenic, hepatoprotective and anticancer effects. Increasing evidence has indicated that NAR has potential for use in the treatment of constipation.

Experimental Quantum Randomness Processing Using Superconducting Qubits.

Coherently manipulating multipartite quantum correlations leads to remarkable advantages in quantum information processing. A fundamental question is whether such quantum advantages persist only by exploiting multipartite correlations, such as entanglement. Recently, Dale, Jennings, and Rudolph negated the question by showing that a randomness processing, quantum Bernoulli factory, using quantum coherence, is strictly more powerful than the one with classical mechanics.

Rosiglitazone attenuates renal injury caused by hyperlipidemic pancreatitis.

Hyperlipidemic pancreatitis (HP) is a serious inflammatory disease with very high mortality and multiple organ injuries including renal injury. Rosiglitazone (Ros), an agonist of peroxisome proliferator activated receptor-γ (PPAR-γ), was reported to show a protective role against pancreatitis. However, whether Ros has an effect on renal injury caused by HP is not yet clear.

Overexpression of integrin-linked kinase (ILK) promotes migration and invasion of colorectal cancer cells by inducing epithelial-mesenchymal transition via NF-κB signaling.

Integrin-linked kinase (ILK), a ubiquitously expressed and evolutionally conserved serine/threonine kinase, has been shown to be aberrantly overexpressed and activated in diversified types of human malignancies, including colorectal cancer (CRC). However, the potential role of ILK in cancer cell migration and invasion remains to be elucidated. In this study, we introduced the human ILK gene into a low ILK-expressing human CRC cell line SW480.

Knockdown of protein phosphatase magnesium-dependent 1 (PPM1D) through lentivirus-mediated RNA silencing inhibits colorectal carcinoma cell proliferation.

Colorectal cancer is one of the most common cancers in the world. Protein phosphatase magnesium-dependent 1 d (PPM1D) is aberrantly upregulated in many human carcinoma cells, and recent research has suggested that it could be a potential therapeutic target of cancer. However, the function of PPM1D in colorectal carcinoma cells is not well studied.

Mutation spectrum in human colorectal cancers and potential functional relevance.

Background: Somatic variants, which occur in the genome of all cells, are well accepted to play a critical role in cancer development, as their accumulation in genes could affect cell proliferations and cell cycle.

Methods: In order to understand the role of somatic mutations in human colorectal cancers, we characterized the mutation spectrum in two colorectal tumor tissues and their matched normal tissues, by analyzing deep-sequenced transcriptome data.

Results: We found a higher mutation rate of somatic variants in tumor tissues in comparison with normal tissues, but no trend was observed for mutation properties.
