I completed chemo at the end of January 2015 and radiation in the next few days (3 day difference due to 2 holidays and one sick day). My medical oncologist ordered a CT scan with contrast to be done 6 weeks after cessation of treatment, and a follow-up of same in 3 more months. We did not discuss additional biopsy.
Meeting with Liver surgeon and colon-rectal doctor later, they both brought up another biopsy.
What is the standard timeline to have a biopsy done of the 25% remaining CT scan findings of mass in anal canal to distinguish scar tissue from tumor--keeping in mind radiation is thought to be continuing to work post-tx?
DX 11/25/2014 by biopsy SCC of the Anal Canal
PET/CT scan 12/2014 Stage 4 SCC of the Anal Canal with mets to Liver (originally 1 20mm spot on left lobe; now 2 spots--3 mm and 5 mm in either lobe seen wih 3/9/15 CT scan with contrast)
TX 12/22/2014 - 2/2/2015 Chemoradiation - Nigro protocol
75% overall improvement
