Background: Older women are less likely to receive standard management for breast cancer than younger postmenopausal women. Whether differences in general health explain variations in the rates of surgery is not known.
Methods: In this prospective cohort study, 76 women aged 65 years or more attending breast units in Greater Manchester completed a survey measuring functional status (Elderly Population Health Status Survey's Activity of Daily Living), generic health status (Short Form 12) and health-related quality of life (European Organization for Research on Treatment of Cancer Quality of Life Questionnaire C30). Case-note review assessed co-morbidity (Charlson Index) and management. Primary surgery for operable breast cancer was investigated using logistic regression.
Results: A Charlson Index of 1 or more did not predict the use of surgery (P = 0.363). However, for each point increase on the 1-4 scale indicating worsening functional status, the odds of having surgery decreased by 16 times (odds ratio 0.063). The odds of a woman of 80 years or more having surgery decreased by a factor of 44 (odds ratio 0.023) compared with women aged 65-79 years, accounting for co-morbidity, functional status, pretreatment stage, social deprivation and type of hospital.
Conclusion: Older women were less likely to have surgery for operable breast cancer than younger women, even after accounting for differences in general health and co-morbidity.

Background: Screening of asymptomatic stage IV breast cancer with brain MRIs is currently not recommended by National Comprehensive Cancer Network (NCCN) Guidelines. The incidence of asymptomatic brain metastasis is not well documented.
Methods: The study is designed as a single arm, phase II trial, with the goal of investigating surveillance brain MRIs in neurologically asymptomatic patients with metastatic breast cancer.

Today, cancer has become one of the leading global tragedies. It occurs when a small number of cells in the body mutate, causing some of them to evade the body's immune system and proliferate uncontrollably. Even more irritating is the fact that patients with cancers frequently relapse after conventional chemotherapy and radiotherapy, leading to additional suffering.

Background: Colon adenocarcinoma (COAD) is a malignancy with a high mortality rate and complex biological characteristics and heterogeneity, which poses challenges for clinical treatment. Anoikis is a type of programmed cell death that occurs when cells lose their attachment to the extracellular matrix (ECM), and it plays a crucial role in tumor metastasis. However, the specific biological link between anoikis and COAD, as well as its mechanisms in tumor progression, remains unclear, making it a potential new direction for therapeutic strategy research.

Introduction: Oncolytic herpes simplex viruses (oHSVs) are a type of biotherapeutic utilized in cancer therapy due to their ability to selectively infect and destroy tumor cells without harming healthy cells. We sought to investigate the functional genomic response and altered metabolic pathways of human cancer cells to oHSV-1 infection and to elucidate the influence of these responses on the relationship between the virus and the cancer cells.
Methods: Two datasets containing gene expression profiles of tumor cells infected with oHSV-1 (G207) and non-infected cells from the Gene Expression Omnibus (GEO) database were processed and normalized using the R software.

Background: Breast cancer remains a leading cause of mortality among women, driven by the molecular complexity of its various subtypes. This study aimed to investigate the differential expression of genes and miRNAs involved in the PI3K/AKT/mTOR signaling pathway, a critical regulator of cancer progression.
Methods: We analyzed tumor tissues from five breast cancer subtypes-luminal A, luminal B HER2-negative, luminal B HER2-positive, HER2-positive, and triple-negative breast cancer (TNBC)-and compared them with non-cancerous tissues.
