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.

CYBERKNIFE TREATMENT - ACOUSTIC SCHWANNOMA

      A 47 year old lady from Kolkata was evaluated for decreased hearing in the left ear. MRI revealed an acoustic schwannoma. BERA (audiometry) revealed profound to severe hearing loss on the left side. She came for radiosurgery. She was irradiated with cyberknife radiosurgery technique in January 2013. Six months later she came for follow up. Her hearing had improved and it was confirmed with an Audiometry then. MRI also showed a decrease in the size of the lesion.

Acoustic schwannoma is a benign neoplasm in the eight cranial nerve.  Surgery for these lesions are complicated by the fact that preservation of hearing is a difficulty. Cyberknife radiosurgery delivers adequate dose to control the tumor growth with preservation of hearing.


We have successfully completed more than 1000 cases 

The patient was under treatment with Dr.Rathna Devi, senior consultant Radiation Oncologist.
