Tumor Progression02:07

Tumor Progression

7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Summary

Intracranial hypertension syndrome significantly increases meningioma recurrence risk. Greater intraoperative bleeding correlates with lower survival rates free of tumor recurrence, impacting post-surgical decisions.

Area of Science:

  • Neurosurgery
  • Oncology
  • Radiology

Background:

  • Meningiomas are common primary brain tumors.
  • Understanding recurrence factors is crucial for patient management after surgery.

Purpose of the Study:

  • To identify risk factors associated with imaging recurrence of meningiomas.
  • To analyze the impact of clinical and surgical factors on tumor recurrence-free survival.

Main Methods:

  • Retrospective analysis of 190 patients undergoing meningioma resection (2009-2019).
  • Univariate and multivariate analyses for risk factors.
  • Linear regression and mean comparison analyses for survival impact.

Main Results:

  • Overall recurrence rate was 38.9% (74 patients).
  • Intracranial hypertension syndrome was linked to higher recurrence risk.
  • Greater intraoperative bleeding correlated with reduced recurrence-free survival.
  • Petroclival location also reduced recurrence-free survival.

Conclusions:

  • Intracranial hypertension syndrome may increase meningioma recurrence risk up to eightfold.
  • Minimizing intraoperative bleeding is vital for improving outcomes.
  • Clinical presentation and tumor location are significant factors in meningioma recurrence.
