choroidal haemangioma (eye lesion)

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.

PROSTATE CANCER - TREATMENT THROUGH CYBERKNIFE

Recent studies have reported results of more than 1,000 patients treated with CyberKnife for prostate cancer, with follow-up up to eight years, which has shown that CyberKnife is very effective at treating localized prostate cancer.

Twenty-one CyberKnife centers in the United States have conducted a trial in which patients with early prostate cancer received five treatments of accelerated hypofractionated treatment the same way the Stanford researchers treated their initial patients. To date, more than 320 patients have taken part in this study. (Forty-two patients are from BIDMC's Keith C. Field CyberKnife Center.)

Results concerning the first 250 patients have been reported; the rate of minor side effects was low, acceptable and similar to what is observed with external beam radiation. Cancer control rates also have been excellent.

Based on these results, most (but not all) insurance compaines cover CyberKnife treatment for prostate cancer. Before you proceed with treatment, ask BIDMC for help determining whether your insurer is one of them.

Many patients with early-stage prostate cancer are candidates for CyberKnife therapy.

She underwent surgery and post operative radiotherapy . She was on follow up. She delivered a baby boy after a couple of years. 4 months after delivery, she was evaluated for weight loss and poor appetite. She was found to  have biliary obstruction .

Pet ct showed a small recurrent mass causing the obstruction. She was re irradiated with cyber knife radio surgery.

Follow up pet ct showed regression in the size and activity of the mass  This patient benefited of this treatment modality without major surgery. She is doing well and enjoying with her baby

Success with Cyber Knife - Hepato Cellular Carcinoma

Hapato Cellular Carcinoma- Successful treatment with Cyberknife 

A 60 yr old gentleman was incidentally found to have a space occupying lesion in the liver  which was diagnosed as hepatocellular carcinoma in June 2013.

He underwent a resection of the lesion in July 2013.Follow up imaging showed a small residual lesion and hence he was started on Tab.Sorafinib from November,2013. But serial imaging showed
an increase in the size of the lesion. Biopsy of the lesion confirmed it to be hepatocellular carcinoma.

The various treatment options were discussed. The patient was not keen for surgery and due to the
proximity of the hepatic vein, RFA was also difficult. It was decided to give radio surgery with Cyber knife to the residual lesion. 

After fiducial placement for real time tracking of the lesion, a total dose of 40 Gy was delivered in 5 fractions. He underwent the treatment quite well with no difficulties. Follow up after 2 months imaging
showed a decrease in the size of the lesion with reduced activity of FDG uptake indicating good response to the treatment.

This is a case study discussion of Dr.Rathna who is a senior consultant , Radiation Oncology.
