Branching out

So. The goddess came through.

First we reviewed my scans and discussed the findings:

Sub-solid mass like opacities in the left upper lobe have increased in size and attenuation since the prior study as described.

Persistent and slightly increased groundglass and interlobular septal thickening in the basilar left lung, suggestive of lymphangitic carcinomatosis. 

Additional sub solid nodules in the left lung are stable or slightly increased in size compared with the prior exam. 

Slightly increased small loculated left pleural effusion.

No surprises there and I am grateful that the word slightly predominates. It is clear where this trend is going but it would also seem that we have time to figure out what the best approach shall be.

First, I am to start nebulizing in an attempt to address my bronchorrhea–the source of the persistent crackle in my left lung. And should it get worse, there is the option of combining pemetrexed with lorlatinib–which would mean leaving the trial and getting lorlatinib by prescription. Avastin could be added to the mix for possibly greater efficacy. Alice is going to start the ball rolling in that direction so that I can apply for financial assistance to help pay for the deductible on lorlatinib–just in case. However pemetrexed kicked my butt energy wise when I was on it seven years ago, so this course will only be as needed.

Most exciting is the news that Alice is going to be opening her own trial at MGH in a couple of months–combining lorlatinib with a MEK inhibitor–binimetinib. She feels this is something that could be effective in my case, so it is my first choice.

Also encouraging is what has been going on behind the scenes in Alice’s lab. My last biopsy identified three secondary acquired mutations. One, G1202R, I had previously and lorlatinib is likely at least somewhat effective against that yet. The other two are newly acquired: S1206F and G1269A. S1206F is rare; Alice has not seen it in any of her other patients. However G1269A is becoming a more common mechanism of resistance to ALK inhibition, along with G1202R.

Alice then shared with me that they have been attempting to make models of all the possible combinations of my three mutations, so as to test drug against them.


I tell you what. This is not the Cadillac of health care, it is the Bugatti La Voiture Noire. It is incredibly humbling to understand the astounding degree of highly personalized effort being expended in the interest of saving my ass. So I damn well better show up.

Yes. That branch just got a little bit thicker–it might even be sprouting some new growth. Alice’s parting words to me were ‘If anyone can do this, you can Linnea.’ To which I responded, ‘If anyone can do this, we can, Alice.’

Row, row, row the boat

I am adrift. Not emotionally, not metaphorically–really, truly at sea.

First, my housing situation; non tenable in all respects and something that has weighed heavily upon my mind for weeks now. There will be a solution but at the moment, it is not obvious.

And then, more importantly, my health.

Lungs and Airways: The patient is status post left lower lobectomy. There is essentially stable ground glass opacity in the left upper lobe on image 64, measures 3.7 cm, measured 3.64 cm in November 2018 . There is essentially stable more confluent consolidative opacity in the LEFT lower lung, along the diaphragm, best seen on image 96. Multiple other ground glass and solid nodular opacities are essentially stable, for example in the RIGHT upper lobe on image 46, 51, LEFT lung on images 51, and 89.

As reassuring as my last scan was, the fact remains that I have multiple areas of cancer in both lungs. And, at long last, some information from the biopsy on 12/14/18.

Essentially, in addition to G1202R, I have now acquired two more secondary mutations, both of which are conferring resistance by compromising the ability of lorlatinib to bind. G1269A and S1206—I am not certain of the letter following 6 on the second mutation but it is no longer Y. More importantly, neither of these newly acquired mutations is actionable. As in, there is no next therapy.

Adrift without a paddle, as it were. Or maybe a more apt metaphor is that I am in possession of one paddle yet, but it is busted. And that would be lorlatinib.

I am still expressing ALK, so Alice is hopeful that lorlatinib continues to confer partial resistance. As she put it, the cancer is working very hard to get around it. My job, in a nutshell, is to hold on (stay alive) until a 4th generation ALK inhibitor is developed.

Big sigh. This is the time to think possible not probable. And also to not only get that good china out, but to use it at every damn meal.
