Biomarker can be used to decide timing fro chemotherapy.

In ray of hope for doctors to identify the tumour normalising period for effective timing of anti-cancer drug treatment, a team of researchers have discovered a new biomarker that can visualise the activity of blood vessels.

Angiogenesis, the formation of new blood vessels, is essential for tumour growth. The team from Osaka University in Japan, in a paper reported in The American Journal of Pathology, described a vascular stabilization biomarker that can visualize blood vessel activity, thus optimising the timing of anticancer therapies including anti-angiogenics.



This can help cancer patients greatly.

Combination therapy using angiogenesis inhibitors and anticancer drugs can improve drug delivery into tumour tissues and prolong progression-free survival. “Vascular normalisation by angiogenesis inhibitors, such as vascular endothelial growth factor (VEGF) signaling inhibitors, is a promising method for improvement of chemotherapy.

“However, it is unclear how we can recognise the ‘window of opportunity’ for the tumour vascular normalising period for effective timing of anti-cancer drug treatment. Therefore, biomarkers delineating this window are essential,” explained Nobuyuki Takakura, Professor at Research Institute for Microbial Diseases, Osaka University.

Angiogenesis therapy is clinically used to suppress tumour growth. Adding an anti-angiogenic drug can boost an anticancer drug’s effectiveness. Basic research indicates that anti-angiogenic therapy allows the blood vessels to return to quiescence and “normalise” so that the anti-cancer drug can penetrate the tumour more effectively. IANS

Advent of Biden Presidency with its resonating calls of 'America is back', 'we will repair our alliances' and 'will engage with the world once again' on one hand and the rise of President Xi Jinping with a stronger hold on China after the Plenary session of the 19th Central Committee of CPC, on the other, have got strategic analysts to examine if a new Cold War was already on the horizon.
