PNA Spotlight: Phillip Cem Cezayirli, MD

This month the PNA Spotlight focuses on neurosurgeon Dr. Philip Cem Cezayirli, part of the Haynes Neurosurgical Group in Birmingham, Alabama. Dr. Cezayirli is affiliated with four local medical centers: Princeton Baptist, Shelby Baptist, Grandview, and Brookwood Baptist Medical Centers.

Dr. Philip Cezayirli

He is a board-certified neurosurgeon with a focus on neurosurgical oncology and spine surgery and is licensed to practice neurosurgery in Alabama.

He earned his MD at the University of Alabama at Birmingham School of Medicine in Birmingham, Alabama. He spent a year studying with Dr. Uğur Türe at Yeditepe University and Hospital in Istanbul, Turkey. He did his neurosurgery residency at the Albert Einstein College of Medicine in Montefiore, Bronx New York. And he completed a neurosurgical oncology fellowship at MD Anderson Cancer Center in Houston, TX.

Dr. Cezayiri was kind enough to speak with the PNA about a range of issues. Here is the conversation, edited for clarity.

Expertise needed for tumors that invade the pituitary’s protective layer

The pituitary gland is surrounded by the cavernous sinus and internal carotid artery. A thin layer of connective tissue separates the sinus and artery from the pituitary gland. Pituitary tumors sometimes invade this protective layer, called the medial wall of the cavernous sinus (MWCS).

That infiltration puts pituitary tumors in close proximity to the internal carotid artery and to cranial nerves, significantly complicating treatment approaches — especially when a tumor needs to be entirely removed to achieve cure.

“Standard procedure would be to resect the pituitary tumor up to the medial wall, to avoid damaging the artery. But if there’s tumor in the wall, the patient won’t be cured,” says Mayo Clinic neurosurgeon Dr. Kaisorn L. Chaichana.

MWCS infiltration is more common with functioning adenomas, such as prolactinomas and tumors that cause acromegaly or Cushing’s disease. Incomplete removal of these tumors can lower the chances of hormone control and increase the risk of tumor regrowth.

Fortunately, neurosurgeons are learning how to meet these challenges. Surgically removing part of the MCWS, to completely resect pituitary tumors, can improve outcomes.

“It’s a formidable challenge,” Dr. Chaichana says. “It takes people well-versed in the surgery, and who have experience, to know where they can open that medial wall. If you’re too far to the side — even by less than a millimeter — you would cut the carotid artery, which would be catastrophic.”

Mayo Clinic neurosurgeons use Doppler ultrasound to guide entry into the cavernous sinus, allowing selective resection of the MWCS. “We listen to the sound of the carotid artery, find a space within the medial wall where the artery isn’t present, and make a small slit in that opening,” Dr. Chaichana says. “Then we remove the wall from the carotid artery.”

It’s also important to limit packing of the cavernous sinus after surgery. “Overpacking that site can cause pressure and injury to the cranial nerves, which could lead to facial numbness and eye motion problems,” Dr. Chaichana says.

A multidisciplinary team that includes ENT/head and neck surgeons, as well as neurosurgeons, provides additional anatomical expertise.

“Very few centers do this procedure. But we’ve seen higher rates of remission for functional tumors when we take out that wall,” Dr. Chaichana says. “For a lot of functional tumors, selective resection of the MWCS can mean the difference between tumor remaining and tumor being gone — and therefore, cure or not cure.”

New acromegaly drug on the horizon

A new drug for treatment and long-term maintenance therapy for acromegaly is now on the horizon. Crinetics Pharmaceuticals recently submitted its first new drug application (NDA) to the U.S. Food and Drug Administration for paltusotine, which is a once-daily oral selectively-targeted somatostatin receptor type 2 nonpeptide agonist.

Crinetics says researchers used data from from 18 clinical trials in the application, including two Phase 3 trials that evaluated paltusotine for acromegaly in medically untreated and treated patients.   Patients tolerated the treatment well, the medication achieved biochemical control by maintaining IGF-1 levels and improved patients’ symptoms compared to placebo.   The company says it expects to hear back from the FDA by December.

Paltusotine, is the first drug of its type to complete Phase 3 clinical development for acromegaly and is now in Phase 2 clinical development for carcinoid syndrome associated with neuroendocrine tumors.  Read the company’s press release here.
