Challenges in Diagnosis & Management
Liquid biopsy
The Gap in Knowledge

Conclusion<br>
slide3. Meningioma The most common primary brain tumor in adults

The majority of meningiomas are benign tumors (WHO I)

Diagnosed with radiological methods

No effective pharmacological intervention has been established to date

Differentiation of meningiomas from other malignancies is challenging

Imaging may not provide information on the grade of meningiomas<br>
slide4. Challenges in Diagnosis Challenges in selecting treatment choice (follow up, surgical resection, Gamma Knife) and extent of tumor resection

Only help identify the tumors when they reach a certain size

Increasing the risk of malignancy overtime

Slow growing tumors and might go undetected for years.

Tissue biopsy; for the definitive diagnosis and histological classification of meningioma;
Invasive method with effectiveness limited to stage of the tumor detected and the area that’s biopsied.
Potential morbidity<br>
slide5. Liquid biopsy Liquid biopsy is:
less invasive
more feasible
easier to repeat
providing valuable information about the tumor molecular structure and genomic dynamics. ME;, K. A. W. H. P. C. W. (n.d.). The use of microfluidic technology for cancer applications and liquid biopsy. Micromachines. Retrieved March 4, 2022, from https://pubmed.ncbi.nlm.nih.gov/30424330/<br>
slide6. Gap in Knowledge c-MYC, FABP7, GATA4 and MAOB; implicated with meningioma grades using tumor tissue samples;

Their roles in diagnosing, staging and prognosis of meningioma is unclear yet.

Have not been studied from liquid biopsy samples before.<br>
slide7. Aim of the study To identify diagnostic and prognostic potential of c-MYC, FABP7, GATA4 and MAOB in liquid biopsy samples of patients with meningioma.<br>
slide8. Materials & Method 20 patients undergoing surgery for meningioma included

May 2017 – March 2021

Tumor and serum samples from 20 meningioma patients who underwent surgical resection in Bezmialem Vakıf university Hospital

Stored at -80°C<br>
slide9. Materials & Method 15 healthy individuals used for controls.

The expression level of FABP7, GATA-4, c-MYC, and MAOB genes were evaluated with real time PCR

Patient’s clinical data including age, gender, radiological findings, simpson grade, post surgical complication and recurrence were retrospectively collected.

GraphPad Prism 3.0 was used for data analysis<br>
slide10. Demographic Information<br>
slide11. Comparision of gene expressions in serum samples between control and meningioma pateints p=0.036 Results p=0.0425 P=0.412 P=0.614<br>
slide12. Comparision of gene expressions in serum samples between Control, Grade 1, and Grade 2
meningioma pateints p=0.032
control and grade 2<br>
slide13. Comparision of gene expressions in Tumor samples between Grade 1 and Grade 2 meningioma pateints p=0.003 p=0.041 p=0.0310 P=0.120<br>
slide14. Conclusion The expression level of GATA-4, c-MYC and MAOB were statistically significant in grade II meningioma tumor samples

The expression level of MAOB was statistically significant in grade II serum samples

Our results suggested that serum expression of FABP7, GATA4, c-MYC and MAOB gene could be implemented as diagnostic marker for meningiomas

Further studies are required ;
With larger sample sizes
The implementation of biomarkers in evaluating:
recurrence probability
course of the disease<br>
