The only stats that I have seen (and are probably dated now with the changing etiology of OC due to HPV) are:

1. IF - you have a recurrence there is an 80% chance it will occur within the first year after Tx. First year recurrences are very dangerous. Take your followups and aftercare seriously. This is also why year one and two are milestone years

2. That number drops to 15% in year 2, post Tx.

3. After year 2 there is a 5% chance of local recurrence.

As far as locoregional and/or distant metastesis I do not know.

Don't freak out at every little sore throat, post nasal drip, ear infection, (or even bad initial scan reports) etc. (or focusing on stats) or you will drive yourself totally nuts - ask me how I know this ;-)
