An Incurable Cancer is no Longer Incurable

Cancer: Everybody’s Enemy

Cancer is widely considered the most feared medical condition globally, affecting both urban and rural environments. While some variations can be prevented or temporarily eradicated, it has long been considered a condition without a long-lasting cure. However, recent breakthroughs are beginning to change that narrative.

T-cell Leukemia

T-cell acute lymphoblastic leukaemia (T-ALL) is an aggressive and fast-spreading cancer of the bone marrow and blood

• Biological Origin: T-cells are white blood cells made in the bone marrow that travel to the thymus to help fight infections.
• Genetic Cause: Mutations in the thymus interfere with normal T-cell development, leading to the onset of T-ALL.
• Clinical Challenge: The condition is terrifyingly fast-developing and has a high relapse rate, with around one-third of patients seeing the cancer return within one to two years.

Cure for the Incurable

Scientists are now using base editing, an advanced form of CRISPR that can change individual DNA letters inside living cells with high precision. This technology powers a treatment known as CAR-T cell immunotherapy

• Modification: A patient’s T-cells are modified to carry a chimeric antigen receptor (CAR), which acts as a guide to identify and destroy unique “flags” on cancer cells.
• Precision Engineering: To prevent the modified cells from attacking each other, scientists remove the CD7 marker.
• Immune Protection: They also remove the CD52 marker to ensure the therapeutic cells are not suppressed

Medicine in the Future

The results of this breakthrough are highly positive

• Patient Outcomes: 82% of patients achieved deep remission, and 64% have remained disease-free, with the earliest patients now three years off treatment.
• Broader Impact: This technique is now being applied to other blood cancers and represents a shift toward treating conditions by addressing their root genetic causes
