Findings from Research

Recent advances in radiation therapy for malignant glioma, such as stereotactic radiotherapy and charged particle therapy, aim to improve treatment efficacy while reducing damage to healthy tissues.

Combining these advanced radiation techniques with targeted biochemotherapies may enhance therapeutic outcomes for patients with malignant glioma, which has historically had a poor prognosis.

Radiation oncologists are exploring various innovative approaches, such as interstitial implants and stereotactic radiosurgery, to enhance cure rates for primary brain tumors while aiming to reduce long-term side effects.

These new radiation techniques must be integrated into a comprehensive treatment plan that includes other therapies to effectively manage primary malignant brain tumors.

Concurrent involved-field radiation therapy (IFRT) and intrathecal chemotherapy (IC) with methotrexate or cytarabine showed a clinical response rate of 34% in 53 patients with leptomeningeal metastasis, indicating its effectiveness as a treatment option.

The treatment had an acceptable safety profile, with 28% of patients experiencing adverse events, and a median overall survival of 6.5 months, suggesting it can be a viable option even for patients who developed leptomeningeal metastasis while on targeted therapy.

Combining chemotherapy delivered through intrathecal and intraventricular routes with radiotherapy has led to long-lasting remissions in patients, suggesting the potential for a 'cure' rather than just symptom relief.

A specific treatment protocol that includes radiotherapy followed by intraventricular administration of methotrexate and cytosine arabinoside shows promise in effectively managing the disease.

Intralesional radioimmunotherapy (RAIT) using monoclonal antibodies against tenascin in 24 patients with recurrent malignant gliomas showed promising results, with a median survival time of 16 months and several patients achieving tumor stabilization or remission.

The treatment demonstrated a favorable safety profile, with no systemic or brain toxicities reported, and only a few cases of human anti-mouse antibody production, indicating that RAIT could be a viable option for managing these aggressive tumors.

Combining metastasis-directed hypofractionated radiation therapy (RT) with systemic therapies can be effective, but specific timing adjustments are necessary to minimize toxicity; for example, BRAF and MEK inhibitors should be suspended a few days before and after RT due to reported toxicities.

Certain therapies like cetuximab and osimertinib are generally safe with RT, but recommendations include suspending them during radiation treatment to reduce potential side effects, highlighting the need for careful management when integrating these treatments.

In a study of 68 patients with advanced solid tumors, the combination of stereotactic body radiotherapy (SBRT) followed by pembrolizumab showed a high one-year treated metastasis control rate of 89.5%, indicating effective tumor response regardless of whether the tumors received complete or partial radiation coverage.

The study found that treated metastasis control (TMC) was significantly associated with improved overall survival, and SBRT altered tumor gene expression by increasing immune-related genes while decreasing those related to cell cycle and DNA repair, suggesting a mechanism for enhanced immune response.

Hypofractionated stereotactic body radiation therapy (SBRT) for early-stage nonsmall cell lung carcinoma was found to be safe and effective, with no significant toxicity reported in a study of nine patients over an 18-month follow-up period.

Using an active breath coordinator (ABC) during treatment resulted in smaller planning target volumes and less lung exposure to radiation compared to free breathing, suggesting that ABC may enhance treatment precision without increasing side effects.

A 68-year-old man with metastatic lung cancer developed myelitis after receiving radiotherapy and immunotherapy, but he fully recovered after stopping pembrolizumab and receiving steroid treatment, indicating that while both treatments can have serious side effects, recovery is possible with appropriate management.

This case suggests a potential interaction between radiotherapy and immunotherapy that may lead to delayed radiation myelopathy, but it also highlights that rechallenging with immunotherapy can be safe, as the patient remained in response without relapse of myelitis after resuming treatment.

In a study involving 15 patients with centrally or superiorly located stage I non-small-cell lung cancer (NSCLC), intensity-modulated proton therapy (IMPT) and passive-scattering proton therapy (PSPT) were found to significantly reduce radiation exposure to surrounding healthy tissues compared to conventional photon stereotactic body radiation therapy (SBRT).

IMPT and PSPT plans not only improved tumor coverage but also minimized the maximum tolerated dose to critical structures like the heart and spinal cord, demonstrating their potential for safer treatment options in patients with challenging tumor locations.

Radiation therapy is crucial for treating adult brain tumors, but its application is changing based on tumor type, with ongoing trials exploring how to enhance its effectiveness and minimize side effects.

For low-grade gliomas, researchers are focusing on identifying patients who can safely delay radiation until necessary, while in cases like meningioma, advanced techniques like radiosurgery are improving outcomes for patients with a good prognosis.

The combination of anti-GITR monoclonal antibody (mAb) and stereotactic radiosurgery (SRS) significantly improved survival rates in a mouse model of glioblastoma, with a cure rate of 24% compared to 0% for either treatment alone, indicating a strong immune-mediated effect.

The treatment with anti-GITR (1) and SRS led to increased infiltration of CD4+ effector T-cells and enhanced production of immune signaling molecules like IFNγ and IL-2, suggesting that this combination effectively shifts the immune response against the tumor.
