Treatment Resistant Cancers

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

Neuro-oncology
Cancer Research
Epidemiology

Background:

An estimated 700,000 individuals in the U.S. live with a brain tumor diagnosis.
Approximately 84,000 new brain tumor cases are projected for 2021.
Malignant brain tumors have a 36% five-year survival rate, significantly lower than benign tumors.

Purpose of the Study:

To highlight the prevalence and survival statistics of brain tumors.
To emphasize the critical challenge posed by glioblastoma (GBM).
To underscore the need for advancements in treating malignant brain tumors and brain metastases.

Main Methods:

Review of epidemiological data on brain tumor incidence.
Analysis of survival rates for malignant brain tumors.
Comparison of survival outcomes for glioblastoma (GBM) versus other malignant brain tumors.

Main Results:

Malignant brain tumors account for 30% of all brain tumors.
Glioblastoma (GBM) patients have a 7.2% five-year survival rate and an eight-month median lifespan.
Brain metastases represent an increasing concern in cancer patient diagnoses.

Conclusions:

Glioblastoma (GBM) remains a highly lethal and treatment-resistant primary brain malignancy.
Survival rates for malignant brain tumors are significantly lower than for benign types.
Further research is crucial for improving the prognosis of patients with malignant brain tumors, including GBM and brain metastases.
