i would like to share our experience with two cases of pigmented villonodular sinovitis we treated at AHRCC. one a 20 year old female with PVNS of left wrist joint, received postop(R0) Radiation to a dose of 40 Gy in 20 Fractions, on follow up for more than 3 years without any local recurrence.The other patuent was a 55 year old male with sacral PVNS, presented with para paresis and pain …received palliative radiation to a dose of 30Gy in 10 #, with good pain releif that sustained for > 6months , thereafter the patient was lost to follow up. so It seems that radiation does works

Indranil will it be possible to create a seperate thread for Benign disease?

This is young lady, radiation may cause late damage. If you are forced to treat then the dose will be an issue, what you are suggesting is probably right. http://www.ncbi.nlm.nih.gov/pubmed/11286830

I remember seeing one at PMH with the Sarcoma team, our patient had multiple recurrences and so we elected to treat. No one knows what dose to give, I think with the new paper that Indranil has quoted. 30-35 Gy conventional fractionation should be enough.
In your patient, you need to talk to your patient and the orthopedic surgeon about possible second resection and pro/con's of RT. Observing your patient is also an option and deffer RT for recurrence.

See this recent publication from Stanford.
http://www.ncbi.nlm.nih.gov/pubmed/19211195

Doses given were around 30-34Gy in 1.8-2Gy per fraction and the functional results were great. 25% rate of failure after RT.

Referred by Orthopedician to another Radiation Oncologist for RT.
