CT BIOPSY LUNG (LEFT) – Details

TECHNIQUE: Diagnostic CT BIOPSY LUNG (LEFT)

INDICATION: Metastatic lung cancer

Consent: The nature of the procedure, including its risks, benefits and alternatives was explained to the patient who understood and gave consent.

TECHNIQUE: 

The patient was placed prone on the CT table. Targeted preprocedure CT images demonstrated a dominant left lower lung mass, not significantly changed compared to chest CT from 5/23/2021. This was identified as the biopsy target.

After identifying a direct path to the target, the overlying skin was prepped and draped in the usual sterile fashion. A “time-out” was performed prior to initiation of the procedure to reconfirm the patient’s name, date of birth, and site of procedure. 15 cc of 1% lidocaine were administered for local anesthesia.

Using CT guidance, a 19-gauge introducer needle was percutaneously placed in the target using posterior approach. The stylet was exchanged for a 22-gauge Chiba needle and aspirates were obtained for slides. Additional fine needle aspirates were collected in a vial filled with normal saline. Subsequently, multiple tissue cores were obtained using a 20-gauge spring-loaded device. Tissue samples were handed to the cytopathology technologist and research assistant.

Post procedure images demonstrated no significant hemorrhage or pneumothorax.

ANESTHESIA: Intravenous conscious sedation was administered by radiology nursing. Continuous hemodynamic and respiratory monitoring was performed, including the use of pulse oximetry.

START TIME: 8:15 AM

STOP TIME: 9:03 AM 

Medications: As per medication administration record

CONDITION/COMPLICATIONS: The patient was brought to the radiology recovery room. Post procedure chest radiographs were obtained one hour and three hours after the procedure.

DISPOSITION: Oral and written post-procedure instructions were given.

IMPRESSION: 

Needle aspiration and core biopsy of left lung mass without immediate complications.

Where do we go from here

inked

Prior to my biopsy, this mystery mark was made on my left shoulder. Not certain as to the significance, but hopefully it aided them in getting the right (make that left) side of me.

Aside from that, I am left with two tiny entry points high on my left breast as well as parallel tracks on my left cheek—a red mark from lying face down on top of the oxygen tubes for more than four hours.

Unlike my previous biopsies (there is a benefit to scar tissue), my lung did not partially collapse this time. Diane was able to take me back home with her with the caution that I was to have no alcohol. Therefore, I only had a small glass of wine that evening 😉

What I know thus far is that they were able to get adequate tissue, including a sample for the sponsor of my trial (a token of appreciation). Over the next four weeks, results of genetic testing should start trickling in. This is the watch and wait part of cancer.

Alice called me yesterday (as well as once the night of the biopsy and she also came to see me twice on the day of—goddess that she is). This was a CT assisted biopsy and the surgeon/radiologist who performed the procedure is  also the radiologist who reads my scans, so he is extraordinarily familiar with my body/cancer. He told Alice that the tumor around my heart (which they did not biopsy–too proximal) has grown very little and that the tissue that they did sample–along the chest wall–is growing rather slowly. She feels radiation may be an option there but not for the cancer hugging my heart. 

Aside from that, there is nothing concrete to discuss yet. I am optimistic, she is cautiously so. 

It really is pull the rabbit out of the hat time. And as important as the magician (Alice) is, I am focused on that rabbit.

Going in

So tomorrow is the big day; my fifth needle core biopsy.

Rather like a space probe, the purpose of this procedure is to look closer; to learn more about the nature of my cancer so that we may make informed treatment decisions. 

My very first biopsy was the most memorable. Four days earlier I had heard the word neoplasm for the first time. In the days hence, I had read up on lung cancer. The statistics were dismal but my differential diagnosis had left room for other conclusions–a recalcitrant pneumonia or a fungal infection.

When they wheeled me to the biopsy room, the patient before me was a prisoner; cuffed and accompanied by two officers. The physician who performed the procedure first marked the point of entry with a black dot–a dark star of a tattoo. As he guided the needle between my ribs he studied the image on the CT scanner and remarked ‘I am almost certain this is a fungal infection. There is no way a young non smoking woman such as yourself could have lung cancer.’

Post biopsy I was to lie still without speaking for several hours. This was made more difficult by the fact that one of the attendants recognized me–she had been a clerk in a store I patronized–and she, apparently unaware of my restriction, kept trying to engage me in conversation.

The next morning my world turned upside down, when I learned that the radiologist was so very mistaken. Young, non smoking women such as myself could get lung cancer.

My next biopsy was almost three years later. It confirmed metastatic spread and I, a IB at diagnosis, was restaged to IV. However, we would also learn that I was positive for an EMLK 4-ALK fusion gene; ALK+. Four months later I went from having no options to enrollment in my first phase I clinical trial, for crizotinib.

Three years later, prior to enrolling in a phase I trial for ceritinib, I was biopsied yet again, in order to better understand my mechanisms of resistance to crizotinib. An acquired secondary mutation, S1206Y, was identified.

After progressing on ceritinib, I had yet another biopsy. The hope was that I would be positive for PD-L1, making me eligible as an early participant in a clinical trial for immune checkpoint inhibitors. Disappointingly, I was not, however it was revealed that I had now acquired yet another secondary mutation, G1202R. This particular mutation was more problematic than S1206Y, as it conferred resistance to all available ALK inhibitors and it was at this point that I returned to chemotherapy, carboplatin and pemetrexed, until lorlatinib (which shows efficacy against G1202R) became available in trial. Some of the tissue from my biopsy was used to attempt to start a cell line as well as build a mouse model of my cancer, but neither proved successful.

So, here I am, once again at a crossroads and seeking direction. Tonight I will sleep at my friend Diane’s house and in the morning she will drive me to MGH. I look forward to the anesthesia (yeah, I’m kind of a sensory freak and I’m not gonna lie, I like going under 😉 ) but I dread the part where you wake up with a dry mouth and then have to lie there unmoving/not speaking. If the biopsy is uneventful, I will go back home with Diane. However, every other time I have suffered a partial pneumothorax (collapsed lung)–a ticket to one night’s stay in the big house.

It is what it is. I am a traveller who’s had a long run on a clear stretch of road; for that, I am exceptionally grateful. Now it’s time to get my bearings and to figure out the best path forward.
