We investigated whether the selective oestrogen receptor degrader fulvestrant could improve progression-free surviva...

Cytoplasmic Cyclin E Predicts Recurrence in Patients with Breast Cancer (2016)
Journal Article

Background: Low-molecular-weight-cyclin E (LMW-E) detected by Western blot, predicts for reduced breast cancer survival, however, it is impractical for clinical use. LMW-E lacks a nuclear localization signal which leads to accumulation in the cytopla... Read More about Cytoplasmic Cyclin E Predicts Recurrence in Patients with Breast Cancer.

Construction of tissue microarrays from core needle biopsies: a systematic literature review (2015)
Journal Article
Albanghali, M., Green, A., Rakha, E., Aleskandarany, M., Nolan, C., Ellis, I., & Cheung, K. (2016). Construction of tissue microarrays from core needle biopsies: a systematic literature review. Histopathology, 68(3), 323-332. https://doi.org/10.1111/his.12802

In some clinical circumstances, core needle biopsy (CNB) may be the only source of material from cancer tissue for diagnostic use. The volume of tissue available in a CNB is low, and opportunities for research use can therefore be limited. The tissue...

ISSN 1932-6203

Triple negative (ER, PgR and HER2 negative) breast cancers (TNBCs) are often considered as a poor prognostic phenotype. There is dearth of evidence showing the prevalence and biological behaviour of TNBCs in older women. This study aimed to analyse t...

Introduction: There is dearth of literature reporting the prevalence and biological characteristics as well as the long-term clinical outcome of human epidermal growth factor receptor-2 (HER2) overexpressing tumours in older women. Currently, resea...
