• Fractionated vs single-dose: Fractionated therapy spreads treatment over weeks, while single-dose delivers high radiation in one session.
• Dose-painting techniques: These methods tailor radiation intensity to heterogeneous tumors, ensuring precise targeting.
• GammaTile brachytherapy: A newer approach that places radioactive seeds directly into the tumor site.

Stereotactic Radiosurgery

Stereotactic radiosurgery uses highly focused beams to treat small tumors. Despite its name, it does not involve surgery. This method is ideal for tumors in hard-to-reach areas. It preserves healthy tissue and reduces recovery time.

• Hippocampal avoidance: This strategy minimizes radiation to the hippocampus, preserving cognitive function.
• Radiation necrosis prevention: Advanced imaging helps distinguish between tumor recurrence and treatment side effects.

Proton Therapy

Proton therapy is an advanced form of radiation therapy. It uses protons instead of photons to target cancer cells. Protons stop at the tumor site, sparing deeper healthy tissue. This makes it ideal for treating tumors near critical structures.

Emerging techniques like FLASH radiotherapy deliver ultra-high doses in milliseconds. This approach shows promise in reducing side effects while maintaining effectiveness. As technology evolves, radiation therapy continues to offer new hope for patients.

Chemotherapy and Its Role in Brain Tumor Treatment

Chemotherapy remains a cornerstone in managing certain types of tumors. This treatment uses specialized drugs to target and destroy tumor cells, often in combination with surgery or radiation. Its effectiveness depends on factors like tumor type, location, and the patient’s overall health.

How Chemotherapy Works

Chemotherapy employs drugs designed to halt the growth of cancer cells. Alkylating agents, such as temozolomide, are commonly used. These agents damage the DNA of tumor cells, preventing them from multiplying. For oligodendrogliomas, the PCV regimen (procarbazine, lomustine, and vincristine) is often prescribed.

However, the blood-brain barrier poses a significant challenge. This protective layer limits the delivery of drugs to the brain. Techniques like focused ultrasound and mannitol infusion are used to disrupt this barrier, enhancing treatment effectiveness.

Innovative Delivery Methods

Recent advancements have introduced new ways to deliver chemotherapy. Gliadel wafers, for example, are placed directly into the tumor cavity post-surgery. These wafers release drugs slowly, targeting residual cells while minimizing side effects.

Convection-enhanced delivery systems are another breakthrough. These systems use catheters to deliver drugs directly to the tumor site, bypassing the blood-brain barrier. This method ensures higher concentrations of treatment reach the affected area.

• Systemic vs. local approaches: Systemic chemotherapy circulates throughout the body, while local methods target specific areas.
• Chemoresistance: Factors like genetic mutations can reduce the effectiveness of drugs over time.
• Maintenance protocols: Low-dose chemotherapy is sometimes used to prevent recurrence.

These innovations are transforming how chemotherapy is administered, offering hope for better outcomes and improved quality of life.
