Welcome to the club no-one wants to join. I think that for a T1 or T2 rectal cancer, making decisions about treatment can be overwhelming. Each option has its own advantages and disadvantages and only you can decide which way to go. The important thing is to have as much information at your disposal as possible in order to make that decision. By coming to this forum you've made a good start, there is a wealth of experience amongst the members of CT.
Other than depth of invasion (T2) of the polyp, were there any other high-risk features such as poor cell differentiation or vascular invasion? These might influence the decision you make about treatment. Perhaps if I share my experience it might highlight some of the options.
So, I had a colonoscopy done by a local GI in June 2014. This identified a 1.5cm tubovillous rectal adenoma. A biopsy was taken but adenoma not removed as too large for the skill level of the GI. Histology showed moderate differentiation but supposedly benign. CEA very low, CT clear. So, I was referred to another GI who specialises in endoscopic mucosal resection (EMR), which is where dye is injected into the polyp to make it lift and then the polyp is removed by cauterisation. All done via endoscopy. This was done in late October 2014. Histology came back T2 adenocarcinoma (this was a bit of a shock
). I was then referred to a internationally respected, highly skilled colorectal surgeon. MRI suggested no lymph node involvement or mets so now staged T2N0M0. What to do next? Colorectal surgeon offered either careful 'watch and wait' or ultra low anterior resection with temporary loop ileostomy. According to the surgeon, 'watch and wait' carried the risk that if there really was lymph involvement and I had a recurrence then there was only a 50% chance of curative 'salvage' resection. Also, I would need to travel 7 hours from home every 3 months for tests, colonoscopies etc, for at least 5 years. If I went ahead with the ULAR and the lymph nodes were found to be clear then 95% chance of 'cure'. Downside of option 2 was chance of needing a permanent colostomy, or ongoing incontinence issues. It was a hard decision but I finally went with the ULAR, which I had on March 4 this year, followed by a reversal of the temp ileo on May 23. As the polyp had already been removed it was too late for pre-op chemoradiation, and as a Stage 1 it was thought unnecessary to have post-op chemo as I had 0 out of 25 lymph nodes positive.
So I'm nearly 13 weeks out from reversal. Yes, the op was a hard one to bounce back from, and the ileo did take some getting used to (not nearly as bad as I thought it would be though). And yes, the first 12 weeks of post-reversal have been frustrating at times. Butt, I'm certainly not tied to the toilet. I've never had any control problems, the urgency stopped after about week 3, and now I very rarely have the clustering which can be a feature of early post-reversal. Yes, I've had to adapt my diet, but I've found that if I introduce something in very small amounts, even if I have an initial reaction, if I re-introduce it later my new plumbing can gradually tolerate it. So my life has change somewhat, but not dramatically.
So, all up, I don't regret the choice I made. I've had a pretty positive experience. However, I made my choice based on what I thought might reduce my chance of recurrence. I really wanted to know for sure that those lymph nodes were clear. If I was just going on what would be the least inconvenience I probably would have chosen the watch and wait option (this would be similar to having less invasive excision and then good surveillance afterwards). I will still need to see my surgeon every 4 months for the next 2 years, then every 6 months for the following 3 years. So, whichever option I chose, I would still be up for a lot of travelling and expense.
One last thing. An important part of my decision was that I had really good family support (my mum is a retired surgical nurse), my kids are adults, and I have a job that is really flexible, so these things made having major surgery much more doable.
Wishing you all the best whichever decision you make. Be sure to keep us posted about your progress, and reach out if you need support.
