[University Health Network @UHN]

A new study published in The Lancet Oncology, from a research team at UHN's Princess Margaret Cancer Centre found that grading of meningiomas may be improved by evaluating the expression of the telomerase reverse transcriptase (TERT) gene.

Lots of fun chatting with Kat Gourd @TheLancetOncol about findings of joint papers on TERT in meningioma
@gelarehzadeh @chloegui_ @ICOMeningioma

submitted together with @wenyalindabi #MSnuderl and team.
Remembering K Groff

Looking forward to working on next steps together!

🚨New #pub @TheLancetOncol from our team @ICOMeningioma , led by ⭐️@chloegui_ ⭐️

In >1,200 #meningiomas, TERT expression—even without mutation—predicts early #recurrence, on par with a #WHO grade increase.

[Chloe Gui @chloegui_]

Excited to share our paper published in @TheLancetOncology showing #TERT expression (independent of mutation) is associated with earlier recurrence in #meningiomas. Thank you to my supervisors @GelarehZadeh @FarshadNassiri, coauthors, editors, reviewers https://t.co/bRlxwDdl2c

[Farshad Nassiri @FarshadNassiri]

Proud of the incredible team - this work reflects #teamscience #mentorship @gelarehzadeh
