That is correct. Unfortunately the TKIs are more for slowing/stopping spread temporarily until the cancer no longer responds - then on to the next one. My doctors were going for curative so I've been going the more traditional route and those will likely be tagged on post-surgery in an effort to keep anything missed in check. Also ALK+ is non-responsive to immunotherapy which would have been nice weapon to have in the arsenal as a cleanup crew.

It may be a pipe dream, but I'm hoping to hold on long enough that some of these new mRNA approaches start offering clinical trials I might be able jump in on.

If you haven't, ask your doctors where it might to spread to, and carefully monitor changes in those areas.

I have experienced three cases in my close relationships where spreading was not picked up for a long time due to being in different body parts.

In one of the cases asthma medication and physiotherapy was prescribed for a year before an unrelated shoulder x-ray caught the attention of the radiologist, and further images showed the cancer had spread to lungs and spine...

[ghjnut]

I hadn't considered that. Thank you, I'll bounce that off them.

According to Vince DeVita (ex head of NCI) it was the way they did things in the early days. Make people survive until something new came up.

Hopefully with the advances in medical research things will accelerate.

I am very glad to hear that you are getting neoadjuvant chemotherapy. I really do hope the resection is complete, and the chemotherapy works.

Regarding "holding on long enough" -- something that there has been shoddy but interesting evidence for over a number of years in dragging yourself further to the right of a Kaplan-Meier plot is dietary modification. As you probably know, one of the hallmarks of cancer is metabolic dysregulation [1] -- specifically a shift towards "anaerobic" glycolysis, that is, the increased uptake of glucose and an increase in the proportion of which ends up as its ultimate metabolic fate as lactate rather than entering the TCA cycle as pyruvate and being oxidised. Some thing that has been explored in the past is providing the organism with ketones as a primary fuel source (which enter the TCA cycle directly as either beta-hydroxybutyrate or acetoacetate) and do not get transported through the glut glucose transporters: in non-cancerous cells with some degree metabolic flexibility there is significant scope for generating other needed metabolites from the TCA cycle and a series of beautiful pathways to let that process happen. As a result, there are a series of papers that indicate that a purely ketone-based diet (exogeneous or endogenous) may be associated with an increase in life expectancy [2, 3, 4; or google scholar GS1] as -- the narrative goes -- cancer cells can't utilise the alternative fuel source as effectively. In mice, with a well controlled tumour xenograft, this has shown to extend survival, fairly significantly.

However, take this with a large grain of salt: there is some evidence that ketone utilisation might be associated with "stemmness" and baddness in general [5, 6] which (and herein starts a "I am hypothesising" warning) may be due to a selection pressure for metabolic flexibility and the return to a more fetal phenotype. The diets are also very difficult to adhere to in patients. These diets are just starting to be assessed properly, in people, in RCTs (e.g. [7]), but I can't find any evidence of a trial in lung cancer patients without a background of smoking specifically.

The most recent major review on the topic I can easily find [8] does seem to hint quite strongly that it might be worth considering, and there is some evidence that it potentiates tumours to other chemotherapies. If I were in your unfortunate position, I would personally discuss the concept with the oncologist in charge of my care – the basic idea "makes sense" to me, at least.

I have been turned off by how the approach is to treat me and I'm primarily a passenger for this ride. In response, I did the same research you did and came across the same stuff. During the chemo/radiation I was on a strict ketogenic diet with a less strict intermittent fasting schedule. Post-surgery I'm going to go the full 9 yards and extend to 7-day fasting once a month after hearing this anecdotal story:

If you are looking for recipes or a second opinion relating to food, my girlfriend (who used to work as an neuro-immunologist doing cancer research) now does keto coaching and also has a ton of recipes online.

Thank you. This is exactly the stuff I'm looking for as a newbie to keto.

"Cancer as a metabolic disease" seems to be getting popular, but traditional oncologists are very suspicious of those approaches. Cases like Steve Jobs gave them a bad reputation, but they should be considered as an addition to traditional therapy, rather than a replacement. It is also harder to design and fund such a study - e.g. dietary changes or repurposed medicine like Metformin may not work accross different cancer types or even different geographies, based on local dietary patterns - especially if expecting the same effects in America, Europe and Asia. Someone has to pay for a study, and it's easier to find funding for $10,000 per month therapy rather than a dietary change or a generic diabetes drug.

https://www.amazon.com/How-Starve-Cancer-Jane-McLelland/dp/0... seems to be recommended as an introduction, but I still didn't finish it.

"Cancer as a metabolic disease" has been known since the 1920s when Otto Warburg discovered that shift towards "aerobic glycolysis"; that is, glycolysis even in presence of adequate oxygen for fatty acid oxidation. It's the basis of some treatment and medical imaging approaches – e.g. 18-FDG PET images the extra uptake of glucose caused by cancers' voracious thirst for glucose.

I agree that interest in diet is an increasing vogue – and I would never recommend replacing a medical therapy with dietary modification, but some of the citations I linked to above indicated that it may potentiate the effect of some other chemotherapies, particularly those that themselves have a metabolic effect. I agree with you about the difficulty in funding such trials, and the difficulty in both monitoring patient compliance with them and obtaining a robust and reproducible readout of their effects. Cancer is a heterogenous disease of life, and its response to therapy is too.

My mother is on Osimertinib for Adenocarcinoma with EGFR Exon 19del mutation. Oncologist only recommended Osimertinib without any additions. Oncologist won't recommend anything that hasn't been confirmed by Phase 3 study. Phase 3 studies in oncology seem to be rare for treatments you can't make money on like $10K per month Osimertinib therapy. There are many things that have been shown effective alongside EGFR TKI inhibitors with minimal side effects based on smaller studies, cell models, retrospective data analyses etc.

So far we added Metformin [1][2] (not as diabetic drug), Aspirin[3], Vitamin D, low glycemic index, no red meat, mediterranean diet, freshly made juices from vegetables and fruits with anti-angiogenic or confirmed anti-cancer properties (e.g. kale, brocolli, apples, carrots, celery, turmeric, red grapes, berries). Metformin has been confirmed with an endocrinologist.

One issue with things like Keto is that it is too extreme to convince a regular 50+ years old person to consider such approaches. And frankly, neither of us has medical training, so we are afraid of trying too-unconventional approaches. Some other medications or supplements I heard recommended, but we didn't decide to include yet are reservatol, simvastatin, altrexone, doxycycline, boswellia, quercetin, keto, intermittent fasting.
