This study aims to compare the impact of awareness campaigns conducted in October for breast cancer and September for prostate cancer on internet search trends among the most populous European countries and Turkey.

N-acetylcysteine prevents cisplatin-induced cognitive impairments in an ovarian cancer rat model.

Cancer-related cognitive impairment (CRCI) is prevalent among cancer patients. A critical disparity in the CRCI field is that most pre-clinical studies have been conducted on young cancer-free male rodents, although CRCI predominantly affects breast cancer and ovarian cancer women survivors. Since oxidative stress is widely implicated in the development of CRCI, we developed an ovarian cancer xenograft rat model of CRCI in Cr:NIH-RNU female rats to examine whether administration of the antioxidant N-acetylcysteine (NAC) prevents cisplatin-induced CRCI without altering its anti-cancer efficacy.

Vitamin D binding protein genetic isoforms, serum vitamin D, and cancer risk in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.

Associations between vitamin D biochemical status and cancer may be modified by vitamin D binding protein isoforms which are encoded by GC (group-specific component). We examined interactions between serum 25-hydroxyvitamin D [25(OH)D], the Gc isoforms Gc1-1, Gc1-2, and Gc2-2, and cancer risk within the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial cohort based on 3,795 cases and 3,856 controls. Multivariable-adjusted logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) of cancer risk according to 25(OH)D quantiles, stratified by Gc isoform.

Epigenetic downregulation of the proapoptotic gene in oral squamous cell carcinoma.

Homeobox A5 () has been identified as a tumor suppressor gene in breast cancers, but its role in oral squamous cell carcinoma (OSCC) has not been confirmed. The Illumina GoldenGate Assay for methylation identified that DNA methylation patterns differ between tumorous and normal tissues in the oral cavity and that is one of the genes that are hypermethylated in oral tumor tissues. The present study obtained more‑complete information on the methylation status of by using the Illumina Infinium MethylationEPIC BeadChip and bisulfite sequencing assays.

Triple-negative ectopic breast cancer of the male scrotum: a case report.

Male breast cancer represents only 1% of all breast malignancies, with ectopic breast cancer in men being even rarer and highly prone to diagnostic challenges. Extramammary Paget's disease (EMPD), a rare cutaneous tumor with non-specific clinical symptoms, is susceptible to misdiagnosis. This report discusses the case of an older male patient who presented with a scrotal mass, later identified as ectopic breast invasive adenocarcinoma upon pathological examination post-lesion excision.

EZH2 elicits CD8 T-cell desert in esophageal squamous cell carcinoma via suppressing CXCL9 and dendritic cells.

CD8 T cell spatial distribution in the context of tumor microenvironment (TME) dictates the immunophenotypes of tumors, comprised of immune-infiltrated, immune-excluded and immune-desert, discriminating "hot" from "cold" tumors. The infiltration of cytotoxic CD8 T cells is associated with favorable therapeutic response. Hitherto, the immunophenotypes of esophageal squamous cell carcinoma (ESCC) have not yet been comprehensively delineated.

Exosomes containing circSCP2 in colorectal cancer promote metastasis via sponging miR-92a-1-5p and interacting with PTBP1 to stabilize IGF2BP1.

Exosomes have emerged as significant biomarkers for multiple diseases, including cancers. Circular RNAs (circRNAs), abundant in exosomes, are involved in regulating cancer development. However, the regulatory function and the underlying molecular mechanism of hsa_circ_0006906 (circSCP2) in colorectal cancer (CRC) metastasis remain unclear.

Isolation method of brain microvessels from small frozen human brain tissue for blood-brain barrier protein expression analysis.

Background: Protein expression analysis of isolated brain microvessels provides valuable insights into the function of the blood-brain barrier (BBB). However, isolation of brain microvessels from human brain tissue, particularly in small quantities, poses significant challenges. This study presents a method for isolating brain microvessels from a small amount of frozen human brain tissue, adapting techniques from an established mouse brain capillary isolation method.

Metastatic papillary thyroid carcinoma in the soft tissue of the breast in a male patient: A case report.

Papillary thyroid carcinoma (PTC) represents ~80% of all thyroid cancers, most frequently presenting in women in the third and fourth decade of life. The first clinical manifestation of PTC commonly includes a palpable mass in the thyroid area or cervical lymphadenopathy in cases of metastatic disease. Hematogenous distant metastases are a sign of an advanced stage of the tumour.

Impaired liver function: effect on paclitaxel toxicity, dose modifications and overall survival.

Background: The anticancer drug paclitaxel is primarily metabolized in the liver. Previous studies have indicated a correlation between impaired liver function and paclitaxel toxicity, which may indicate dose reduction. Since the evidence is limited, the aim of this study was to investigate the effect of impaired liver function on the hematological toxicity of paclitaxel, dose modifications and overall survival (OS).

Changes in essential cancer medicines and association with cancer outcomes: an observational study of 158 countries.

Background: Cancer is a major cause of mortality worldwide, and differences in cancer mortality rates between countries are, in part, due to differences in access to cancer care, including medicines. National essential medicines lists (NEMLs) play a role in prioritization of healthcare expenditure and access to medicines. We examined the association between amenable cancer mortality and listing medicines used in the management of eight cancers (non-melanoma skin, uterine, breast, Hodgkin lymphoma, colon, leukemia, cervical, and testicular) in national essential medicines lists of 158 countries and summarized changes to the inclusion of cancer treatments in NEMLs.

Primary anorectal mammary-like adenocarcinoma: a potential diagnostic pitfall with conventional colorectal adenocarcinoma.

Anogenital mammary-like glands (AGMLGs) are present in the anogenital region that bear striking morphologic and protein-expression similarities to mammary glands in the breast. AGMLGs can give rise to both benign and malignant lesions which mimic primary breast lesions. Herein, we report two mammary-type adenocarcinomas arising from AGMLGs, including one in the previously unreported site of the rectum.

Utility of colposcopy for the screening and management of cervical cancer in Africa: a cross-sectional analysis of providers' training and practices.
