Margins, PEGs, Modalities and Decisions
A bit of water under bridge since last post (not including the TumourWatch Updates).I see I was complaining about my throat and looking forward to an appointment to get the results of my tonsillectomy biopsy.
As detailed in the TumourWatch, the news was a bit disappointing - that is we had already had the good news 'leaked' to us regarding the positive HPV16 association - but we were hit with the news about the 'margin' being too small. Margins hey! So I guess I would picture a cricket ball (my tonsil-tumour mass), the surgeon removes the whole mass, the inner core of the ball, the cork bit is the nasty little tumour and the leather outer is normal, non-cancerous tissue. As long as that leather outer bit is thicker than 2mm, then they will consider that region as now cancer free and not requiring further treatment. Most of my cricket ball had a nice thick outer layer, but in one area the outer layer got down to 0.7mm. So because of that 1.3mm shortfall, I now have to have that area of my throat radiated - with a lower dose that if I had not had the tonsillectomy, but still a bit disappointing.
So now for another unexpected burden. We were being asked to make a decision. Whaaaaat! Some early advice from a mate who had come out the other side of lymphoma was to 'just do what I was told'. I was ready for that. Take this drug, rest, exercise, put on weight, eat the scratchy toast - I am your obedient patient awaiting your next command. So please don't now ask me to make a decision.
Do you want to have surgery on your neck to remove the cancerous nodes - then have RadioT and ChemoT OR do you just want to have RadioT and ChemoT? After a few moments of getting over the fact that the expert was asking me to make such a massive decision, my brain kicked into gear.
After some interrogation it was determined that there was a slight chance that after surgically removing the nodes they would find that the actual tumours were smaller that they had predicted based on UltraS and CT and they might be able to downgrade RadioT dosage a bit. The more likely outcome was that I would undergo the pretty invasive neck dissection, only to have exactly the same dosage of RadioT and ChemoT anyway. This was the response I was getting from a surgeon, who you would expect would have some bias toward surgery. We were getting the idea that the non-surgical option was the go.
The next day (Friday 20/4) we met Dr S, the oncologist at FPH. Tracey our nurse practitioner was there to hold our hands and help absorb, interpret and amalgamate the information and outcomes from all the different meetings. What a fantastic service. I am such a fan of nurse practitioners. I had a mate who's wife was, as far as I could tell, involved with the phase-in of this awesome concept. I also have a mate who is a NP. It is just such a wondeful and rare example, of common sense bubbling up through the viscous 'gloop' of procedure, bureaucracy and politics that seems to smother health systems worldwide. Anyway suffice to say that the funding for Tracey's role is much appreciated. To have someone there as a liaison and an advocate across the different health professionals has been wonderful. On top of all her expertise, availability and interpersonal skills, she can get you from point A to B anywhere in the FMC/FPH complex, so that alone is well worth it!
Dr S also presented us with the same choice. He did not shed a whole lot of light on the decision, but he did refer to evidence that indicated three modalities were statistically no more effective than two modalities. So he was basically suggesting that we don't have the surgery either.
We got the hint and declared that we had chosen the no surgery option, but there was a bit of 'well if that's what you want...hmmm'. Huh?
Time for the next decision.
Do we want to be part of a clinical trial?
The 'Javelin Trial' is a phase III trial of an immunotherapy drug called Avelumb, click here for more details. Roxy Music wrote the theme song for the trial, click here for more details (It's actually Avelumab - but that doesn't really work for Roxy Music, so it is called Avelumb in Australia - you say Aluminum I say Aluminium, let's call the whole thing off!)
Once again, a decision to be made - it sounded pretty good to us.
We were well informed and more of a consensus, in the affirmative, was presented.
The only sticking point, was that my tumour might not be large enough. So off to Repat Radiology we trotted for another CT Scan to see if it had got larger - I assured them it had!
Meetings were set up, paperwork was handed over, a one week delay in RT was set up - we we were assured was insignificant, but a few days later we were given the sad news, 'sorry sir, your tumour is too small'. Once again it came down to millimetres. It needed to be 60mm, it had grown, but only to 56mm. We were distraught! No, no we weren't. Tumour too small = happy.
Also, we were advised that based on the 8th Edition of HPV Head and Neck cancer staging - we would go from s Stage III to a Stage I cancer - 4mm hey! Due to the very recent nature of these changes, we will naturally be interchanging between the two, depending on whether I am telling my poor Mum (Stage I), or the general public (Stage III - ohhhrrr).
We were also advised that in a few years the RT protocols, for HPV positive cancers, will catch up and people probably won't be getting as fried as I am about to be - that is nice to know (I'm not being sarcastic - science in action!).
I am writing this retrospectively, and I went into the future just to follow that storyline.
Now back to the present - as per this blog - Friday 20 April.
Another decision to be made!
Do I have a percutaneous endoscopic gastrostomy (PEG) inserted before I start treatment, or do I try and hold off and maybe avoid it altogether? As the great philosopher Charlie Brown would say, "Good Grief!".
Righteo - roll out the pros and cons...
Pros:
1. I will probably have it anyway, as I am apparently a 'slight man'...hmmmm. I guess I have to take the good with the bad. I have been called 'young and fit' so many times in the last two weeks, I have to take the not so complimentary, and probably more accurate, observations as well.
2. I am better off having the procedure, which is under GA, whilst I am not on a course of ChemoT and RadioT.
3. It will avoid the more conspicuous naso-gastric tube, which would be used to get me through until I can have a PEG inserted if required later.
4. I can keep ahead of the nutrition curve and also keep up my hydration - which gets a bit awkward when your throat has been fried (about 4 weeks in).
Cons:
1. I might avoid the risks associated with the procedure.
2. It might become dependent on it and avoid using, and thus maintaining my swallowing and food processing muscles (this is highly unlikely when you live with one of the best speech pathologists in the Southern Hemisphere...if not the world!)
So the 'pros' have it. What do the experts think? All those who think I should do the PEG insertion say 'aye', those not in favour say 'neigh'.
Luckily my RadOnc - that's what the cool kids call a Radiation Oncologist - Dr P, had already done the survey for me, when we met him four days later (Tuesday 24 April). The results.. Dr Ooi (ENT Surgeon) - neigh; Dr P (my RadOnc) - neigh; Tracey (ENT NP) - aye, Dr C (another RadOnc who had been dragged into it) - aye, Dr S (Oncologist) - slid down into his seat and did not respond. Oh great 2-2 from the medical team.
Further research and conversations with the cancer team speech pathologist and dietitian and with an anaesthetist led us to go with the pre-emptive PEG. Turns out they had sort of assumed that anyway and before we had a chance to let them know, I was advised of the procedure date.
Hmmmm...OK.
To their credit, it was explained that they had seen a window and were quite happy for me to pull out at the last minute.
