I think the head & neck cancers are far more complicated that that ... And, I think that surgery is still standard managment, with chemoRT being a more than reasonable alternative ...
Being at a place where the ENT surgeons are absolutely amazing and after having given a talk on larynx preservation along with one of the head & neck onco-surgeons, I'd have to say that it is definitely not clear cut. In fact, I think there are more than enough questions left unanswered ...
Structurally preserving a larynx through chemo/IMRT is hardly the same as functionally preserving a voice. Also, treating a larynx cancer with surgery hardly precludes having a voice, and modern post-laryngectomy QOL surveys have shown this to be the case. QOL surveys are equivocal on whether it improves a patients' QOL to have undergone chemoRT and 'spared' the larynx vs. having a 'voice preserving' surgery performed by an expert H&N oncologist. This is quite a different different procedure than a TL/neck dissection performed out in the community, and also quite different than the procedure performed >20 years ago, in the era of the VA Larynx study.
I understand epidemiological data is retrospective and merely hypothesis generating, but it is thought provoking that if you look at the SEER data as definitive chemoRT has transitioned to a primary therapy for larynx cancer, mortality has crept up. One can come up with many possible and plausible reasons why this is being seen, but the elephant in the room is obvious ...
And prostate ... again, it's not that easy! If, in fact, all modalities are 'equal' for favorable risk disease, it has more to do with tailoring treatment to a patient's individual needs and desires. I know a few rad-oncs that have had RPPs performed on themselves. I'm not sure what I'd choose for myself. The other thing - unless we start performing the prostate biopsies ourselves, practice patterns will probably plateau. It's up to the urologist to send us the referrals, you know? Another obvious concern is reimbursements. Urologists are skimping on surgery b/c they can make more moolah through technical fees from owning a linac. If the reimbursements come back down, they'll start cutting more.
I think saying that rad-onc has the surgeons 'trembling' is about as accurate as saying that radiation will become obsolete over the next few decades. It's going to have to be multimodality therapy to achieve the best outcomes, at least for the next few decades.
Anyone fill out that ARRO survey? Very interesting questions about the our field turning more like med-onc (a primary service, inpatients, administering biological modulators, etc.) or more like IR (where the patient is a prepped body and you are a hired gun). I kinda like it the way it is ... And I certainly don't want to be responsible for giving Erbitux!
