Master ShreeVaishnav – Kerala, India

Radiation therapy is one of the most important tools to combat cancer. However, conventional radiation therapy is long course (usually 6 to 7 weeks) treatment and may have severe acute side effects including skin and mucosal reactions, diarrhea, feeding difficulties and others. Higher dose radiation is also not possible to deliver due to limitations related to toxicities. CyberKnife is a precise radiation therapy technique by which high dose radiation therapy can be delivered only to the tumor and minimal dose to the normal structures. CyberKnife treatment is a short course treatment (usually only one to 5 days) and have no or minimal side effects. Many tumors which are ‘resistant’ to conventional radiation are ‘sensitive’ to high dose radiation delivered by CyberKnife. “CyberKnife has unique system that it can track moving tumors and treat them with immaculate accuracy”. Tumors in moving organs such as lung and liver can be treated most effectively CyberKnife. Dr Debnarayan Dutta, Consultant in Radiation Oncology at Apollo Speciality Hospital, Chennai commented “there are few tumors which were thought to be not treatable are now being treated successfully with CyberKnife”.

Master ShreeVaishnav, a 6 year old boy from Kerala suffering with choroidal haemangioma (eye lesion) had vision loss in both the eyes, he was referred from Sankar Netralaya for treatment. He was treated with CyberKnife and at 2 months follow up evaluation his vision had dramatically improved. “We are thankful to Dr Dutta for giving vision back to my son” told ShreeVaishnav’s father who was elated about CyberKnife. “CyberKnife has opened a modern and effective option for these diseases and we are happy with the result” said Dr Prativa Mishra, eye specialist involved in ShreeVaishnav’s treatment.

CyberKnife is a revolution in cancer treatment; it provides effective, short course, minimal toxic and high dose treatment in brain, lung, liver, pancreas, prostate, head and neck and many other tumors.
