Omics-based molecular techniques in oral pathology centred cancer: Prospect and challenges in Africa

: The completion of the human genome project and the accomplished milestones in the human proteome project; as well as the progress made so far in computational bioinformatics and “big data” processing have contributed immensely to individualized/personalized medicine in the developed world.At the dawn of precision medicine, various omics-based therapies and bioengineering can now be applied accurately for the diagnosis, prognosis, treatment, and risk stratifcation of cancer in a manner that was hitherto not thought possible. The widespread introduction of genomics and other omics-based approaches into the postgraduate training curriculum of diverse medical and dental specialties, including pathology has improved the profciency of practitioners in the use of novel molecular signatures in patient management. In addition, intricate details about disease disparity among diferent human populations are beginning to emerge. This would facilitate the use of tailor-made novel theranostic methods based on emerging molecular evidences

Long-term cardiac and vascular disease outcomes following adjuvant tamoxifen therapy: current understanding of impact on physiology and overall survival

The relative impact of tamoxifen therapy in women with breast cancer on overall survival, especially as it pertains to cardiac and cardiovascular outcomes, remains under debate in the literature. This review focuses specifically on outcomes of studies that examined large clinical trials with longest duration in patient follow-up relative to these parameters in which compliance with therapy could be documented. Over time, evidence supports potential cardioprotective effects and capacity of adjuvant therapy to improve lipid profiles in women treated with tamoxifen. While some benefit to cardiac health is supported, outcomes related to cardiovascular events remain variable across studies and challenging to interpret. In summary, overall survival in women treated with tamoxifen over time has increasingly shown a trend towards positive outcomes in the context of evaluation of post-treatment cardiac and vascular health. Potential mechanisms underlying the cardioprotective effects of tamoxifen are briefly discussed
