About
Dr. R. Kannan is a radiation oncologist whose research focuses on the application of advanced stereotactic radiosurgery (SRS) and robotic radiosurgery in the management of challenging oncologic conditions, particularly hepatocellular carcinoma (HCC) and brain metastases. His major contributions include pioneering prospective studies on robotic radiosurgery for HCC patients with portal vein tumor thrombosis (PVTT), a historically difficult-to-treat complication. His 2021 interim results, with 15 citations, demonstrated promising response rates and survival outcomes, establishing a new therapeutic avenue for this cohort. Dr. Kannan further refined this work in 2024, correlating PVTT response with survival functions. Additionally, he conducted a prospective evaluation of SRS-only treatment for oligo-brain metastases in Indian patients, analyzing response, recurrence patterns, and toxicity in a large cohort of 138 patients. This work provides critical, population-specific data on SRS efficacy. His research is notable for its prospective design and focus on underrepresented patient populations, offering high-quality evidence for clinical decision-making in stereotactic radiotherapy.
