Title: Innovations in Cancer Treatment by Long Dang

Introduction

Long Dang is a prominent inventor based in Baltimore, MD (US), known for his significant contributions to cancer treatment. He holds 4 patents that focus on innovative therapeutic approaches to combat tumors. His work is particularly notable for its potential to address the challenges posed by poorly vascularized regions of tumors.

Latest Patents

One of Long Dang's latest patents is centered on combination bacteriolytic therapy for the treatment of tumors. Current approaches for treating cancer are limited, in part, by the inability of drugs to affect the poorly vascularized regions of tumors. Dang and his team have discovered that spores of anaerobic bacteria, when combined with agents that interact with microtubules, can effectively destroy both the vascular and avascular compartments of tumors. They found that two classes of microtubule inhibitors exert markedly different effects. Some agents that inhibited microtubule synthesis, such as vinorelbine, caused rapid, massive hemorrhagic necrosis when used in combination with spores. In contrast, agents that stabilized microtubules, such as the taxane docetaxel, resulted in slow tumor regressions that killed most neoplastic cells. Remaining cells in the poorly perfused regions of tumors could be eradicated by sporulated bacteria. Mechanistic studies showed that the microtubule destabilizers, but not the microtubule stabilizers, radically reduced blood flow to tumors, thereby enlarging the hypoxic niche in which spores could germinate. A single intravenous injection of spores plus selected microtubule-interacting agents was able to cause regressions of several tumors in the absence of excessive toxicity.
