Rickker,
I know how deep a T3 has gone. If you read my post, the TAE would only be appropriate for a clincially staged T3 IF after neoadjuvant chemoradiation there was a very good response - meaning that the tumor had shrunk significantly to something pathologically a T1 or less. No, no nodes are taken although during the excision, some may be found in the excised specimen. This is also precisely why the follow up should include frequent rectal ultrasounds to check that cancer hasn't reappeared in the local pelvic nodes. Even with a T1 (clincially staged before neoadjuvant chemoradiation) there is no way to know if there is nodal involvment. Keep in mind that there are many many stage IIIA which mean that those people may have a T1 tumor and still have one or more nodes involved. My point is that even with a T1 tumor, depending on the individual's anatomy there could be nodal involvement. TAE surgery needs to be a decision made by the patient and if the patient is informed, is willing to be followed up meticulously and if his/her doctors are all on board with adjuvant treatment, then it's the right decision for that patient.
You know, not trying to be difficult here, but you could easily have any patient with no local nodal involvement that has nodal involvement somewhere else or even mets. Let's take a stage IIA patient who has surgery. The pathology report shows no local nodal involvement - but that doesn't mean that there's not cancer somewhere else in the body - maybe in a distant node, maybe in the lung or liver. It's not at all uncommon. My point is you just don't know which is why more oncs are routinely giving stage IIA patients adjuvant chemo - to be on the safe side.
It's up to each of us to decide what is right for us - with respect to surgery and/or treatment. Personally, I chose the excision after doing extensive research and making sure that all of my docs were 'on board' with the adjvuant plan. That was the right decision for me. You chose your surgical and/or adjuvant treatment options and again, those were right for you. We have to respect that each of us makes our own decisions based on many factors and for me, quality of life afterwards was a HUGE influencing factor. I'm also realistic enough to know that cancer follows no guidelines - follows no rules which is precisely why we are all watched like hawks. FYI - treatment plans change all the time based on new studies, new stats, etc. For example, more and more colorectal surgeons are changing their approaches to the timeframe after neoadjvuant chemoradiation before they do surgery based specifically on the newer studies showing a slightly longer wait time produces better shrinkage results. There have been and are right now clinical studies that are dealing with the issue of TAE after complete clinical or good response to neoadjuvant chemoradiation. My point is doctors have to be willing to change and they do as more and more studies come out proving the efficacy of one treatment or another.
You are quite right that TAE is not good for a T3 tumor - but that doesn't mean it isn't necessarily a viable option for a T3 tumor that has been downgraded to a T0 or a T1 after neoadjuvant chemoradiation. The trick is to figure out who is a good candidate and who isn't for this type of surgery. The small studies available have shown that those patients who DO respond quite well to neoadjvuant chemoradiation and who have follow up chemo do do quite well (provided of course they are followed up with the normal testing, etc.). I can only speak for my surgeon who was very insistent that based on the pathology report, we would decide what the next step was. In other words, if that path report came back with a tumor that was anything more than a T1 - it was an automatic LAR for me - something I agreed to. In my case, there were no cancer cells left but had that path report showed a T2 or higher, yes, I would have had the LAR.
It's not as cut and dry as saying that all clinically staged T3 tumors are not candidates for this type of surgery. The key is the response to the chemoradiation.
