What this trial studies

This study aims to evaluate the effectiveness of reduced-dose radiotherapy in treating metastatic tumors that have a pathogenic mutation in the ATM gene. Researchers will determine the minimum effective radiation dose that can still provide therapeutic benefits for patients with these specific tumors. The study focuses on patients who are referred for palliative radiotherapy and have a confirmed malignancy with at least one metastatic lesion. The goal is to improve treatment outcomes while minimizing radiation exposure.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with metastatic cancer and a confirmed pathogenic mutation in the ATM gene.

Not a fit: Patients with serious medical co-morbidities or those who have previously received radiotherapy to the treatment site may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and safer treatment options for patients with metastatic cancer and ATM mutations.

How similar studies have performed: Other studies have explored reduced-dose radiation in various contexts, but this specific approach targeting ATM mutations is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Histologically confirmed malignancy with at least one metastatic lesion referred for palliative radiotherapy
* Pathogenic mutation in ATM (somatic and germline allowed)
* ECOG performance status 0-2
* Age ≥ 18 years.
* Able to provide informed consent.
* Patients at reproductive potential must agree to practice an effective contraceptive method during radiation treatments.
* Expected life expectancy of at least 6 months

Exclusion Criteria:

* Previous radiotherapy to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances.
* Serious medical co-morbidities precluding radiotherapy.
* Pregnant or breast-feeding women.
* Lesions excluded from de-escalation include regions in which the risk of local disease progression is unacceptably high, including CNS disease and cord compression, and areas in which re-irradiation would not be feasible, including spinal cord overlap.
