Pleased to share another #meningioma paper out today in @NatureGenet, demonstrating the key role of both neoplastic & non-neoplastic cell programs in shaping #microenvironment and clinical behaviour

New study out in @LancetDigitalH, demonstrating the utility of #AI for molecular profiling of meningioma with histology images alone

Grateful to mentors, collaborators, reviewers, editors, and patients who made this work possible. @DrAdriFonseca @Kenneth_Aldape @gelarehzadeh

[Leo Yefet @lsyefet]

Pleased to share our work published in @NeuroOnc analyzing >21,000 CNS tumors, highlighting adolescents & young adults. AYA patients exhibit a unique tumor spectrum bridging pediatric and adult disease, underscoring the need for further dedicated research.

Congratulations to all medical students throughout the country.

Welcome to neurosurgery Aram, Mohammed, Lyndon, Alexandra, Umar, Yujin, and Farbod!

[University of Toronto Neurosurgery @UofTNeuroSurge]

We are excited to introduce you to our seven outstanding individuals who will be joining us as #PGY1s in July! Please join us in welcoming them to the #UofT #Neurosurgery family!

[International Consortium on Meningiomas (ICOM) @ICOMeningioma]

Read the new study in @NeuroOnc demonstrating that a molecular tool built in a predominantly adult #meningioma cohort does not generalize well to #adolescent and #YoungAdult (AYA) patients:

[Alex Landry @ap_landry]

New #zadehlab paper out in @NeuroOnc providing a data-driven approach for integrating prediction models for personalized meningioma care.

Special thanks to mentors @gelarehzadeh @FarshadNassiri, helpful reviewers, and many collaborators @ICOMeningioma

[Leo Yefet @lsyefet]

As a field, we need to prioritize AYA-focused research to ensure that precision neuro-oncology is equitable across the lifespan. Grateful to our editors, reviewers, collaborators, our patients and families, and to @gelarehzadeh for supervising this work.

[Leo Yefet @lsyefet]

Excited to share our new study in @NeuroOnc in which we show that a molecular tool built in a predominantly adult meningioma cohort does not generalize well to adolescent and young adult (AYA) patients.

[Leo Yefet @lsyefet]

We show that an age agnostic recurrence prediction model performed poorly in AYA patients. Retraining the model on an age-specific cohort improved performance substantially.

Join us today for this year's first Neurosurgery Virtual Electives session for medical students. Led by our neurosurgery residents, these sessions are designed to provide an overview of the neurosurgical subspecialties practiced in Toronto! https://t.co/Qav4XnkefP

We are excited to be recruiting to a new clinical trial for #glioblastoma #GBM #braintumor available @MayoClinic @MayoClinicNeuro
Testing whether regulating & monitoring #glucose #sugar does improve survival

We had the pleasure of hosting all first year neurosurgery residents from across Canada for the 14th Annual Canadian Neurosurgery Rookie Camp. A huge thank you to our dedicated faculty, residents, sponsors, and support teams who made this event possible. @uoftmedicine

[Nir Lipsman @DrNirLipsman]

Proud to kick off national neurosurgery rookie camp in Toronto, hosted by @UofTNeuroSurge at the incredible @TemertySimCtr facility.

Outstanding faculty from across the country, teaching the best and brightest of next generation neurosurgeons.

Masterclass in skull base cadaveric dissections lead by @FarshadNassiri for our medical students and neurosurgery residents at one of our dedicated microsurgical courses @uoftmedicine @UofTSurgery

[University of Toronto Neurosurgery @UofTNeuroSurge]

Our PGY1s, Bianka, Eddie, Sabra and Seika, just finished their crash course in neurosurgery! They are phenomenal and we are excited to see their journey in neurosurgery unfold.
