Background: We present a case of recurrent colon cancer detected by routine, annual Papanicolaou screening.
Case: A 59-year-old African American woman who had been treated for T2N0M0 (stage II, Dukes A) colon cancer 2 years before to presentation had a Pap smear showing a high-grade squamous intraepithelial lesion with a normal cervical biopsy result. Because of this discrepancy, a loop electrosurgical excision procedure and endocervical curettage were performed and showed atypical glandular cells suspicious for adenocarcinoma. Subsequent colonoscopy showed recurrent adenocarcinoma of the colon. The patient underwent an en-block total abdominal hysterectomy and anterior-perineal resection showing invasion of recurrent colon cancer into the uterus and cervix.
Conclusion: In patients with a history of extrauterine adenocarcinoma, abnormal Pap screening may indicate recurrent or metastatic carcinoma.

Colon cancer is a significant health concern, and obesity is a well-established risk factor. However, previous studies have mainly focused on assessing body weight as a risk factor for colon cancer at a specific time point. This nationwide cohort study investigated the association between body weight changes, which can fluctuate throughout an individual's lifespan, and the incidence of colon cancer using the South Korean population database provided by the National Health Insurance Service (NHIS).

Introduction: The standard of care for stage III colon cancer is 3 or 6 months of double-drug regimen chemotherapy following radical surgery. However, patients with positive circulating tumour DNA (ctDNA) exhibit a high risk of recurrence risk even if they receive standard adjuvant chemotherapy. The potential benefit of intensified adjuvant chemotherapy, oxaliplatin, irinotecan, leucovorin and fluoropyrimidine (FOLFOXIRI), for ctDNA-positive patients remains to be elucidated.

In this study, novel 2-styrylquinoline derivatives possessing a planar aromatic system and a flexible side chain with an amino substituent were designed and synthesized as DNA-intercalating antitumor agents. The cytotoxic activity of the synthesized compounds was evaluated against four cancer cell lines including MCF-7 (breast cancer cells), A549 (lung epithelial cancer cells), HCT116 (colon cancer cells) and normal cell line L929 (mouse fibroblast cell line). The results displayed that the anti-cancer activity of the target quinolines is sensitive to the lipophilic nature of the C-6 and C-7 quinoline substituents.

Targeted therapy is preferable over other therapeutics due to its limitation of drawbacks and better pharmaceutical outcomes. VEGF and its receptors have been observed to be hyper-activated in many cancer types and are considered promising targets for assigning anticancer agents. The current study is directed towards synthesis of novel antiproliferative 2-oxoindolin-3-ylidenes incorporating urea function with VEGFR-2 properties.

Mitochondrial DNA (mtDNA) is highly polymorphic, and host mtDNA variation has been associated with altered cancer severity. To determine the basis of this mtDNA-cancer association, we analyzed conplastic mice with the C57BL/6J (B6) nucleus but two naturally occurring mtDNA lineages, and , where mitochondria generate more oxidative phosphorylation (OXPHOS)-derived reactive oxygen species (mROS). In a cardiac transplant model, Foxp3+ T regulatory (Treg) cells supported long-term allograft survival, whereas Treg cells failed to suppress host T effector (Teff) cells, leading to acute rejection.
