What is the purpose of this trial?

This trial explores a new approach to radiation therapy for individuals with triple negative breast cancer, a type that does not respond to common hormone treatments. The study aims to determine if a genomic profile can enhance the effectiveness of radiation therapy. Participants will receive either genomically guided radiation therapy, tailored to their genetic makeup, or standard radiation treatment. This trial suits individuals who have already undergone a lumpectomy for triple negative breast cancer. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group, offering participants an opportunity to contribute to advancements in personalized cancer therapy.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It might be best to discuss this with the trial coordinators or your doctor.

What prior data suggests that genomically guided radiation therapy is safe for breast cancer patients?

Research has shown that using genomics to guide radiation therapy offers a promising way to treat breast cancer. This approach customizes radiation treatment based on the tumor's genetic details, aiming to enhance effectiveness and reduce harm.

Previous studies found that patients with certain genetic traits did not experience increased sensitivity to radiation, indicating that the treatment is generally well-tolerated. By focusing on genetic information, the radiation dose can be adjusted, potentially reducing side effects.

As this study remains in the early stages, safety is still under assessment. Current findings suggest some evidence of safety, but further research is needed to confirm these results. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for breast cancer?

Researchers are excited about genomically guided radiation therapy for breast cancer because it personalizes treatment based on a patient’s unique genetic makeup. Unlike standard radiation therapy, which is generally uniform for all patients, this approach uses a Radiosensitivity Index (RSI) to determine how sensitive a patient's cancer cells are to radiation. This allows for a more tailored treatment plan that could potentially enhance effectiveness and reduce side effects. By optimizing radiation doses specifically for each individual, this method aims to improve outcomes and offer a more targeted approach to fighting breast cancer.

What evidence suggests that genomically guided radiation therapy could be effective for breast cancer?

Research has shown that genomically guided radiation therapy could be promising for treating breast cancer, particularly triple-negative breast cancer. This trial will compare two approaches: one arm will use a Radiosensitivity Index-optimized method, adjusting the radiation dose based on the tumor's genetic details to potentially enhance treatment effectiveness. The other arm will use standard radiation therapy. The genomic-adjusted radiation dose (GARD) customizes the radiation treatment, making it more precise for each patient. Early results suggest this approach might reduce the chance of cancer recurrence by targeting cancer cells more accurately. This method aims to improve outcomes by focusing on the cancer's unique features. ^{1 2 3 6 7}

Radiogenomics aims to understand how genetic differences affect individual responses to radiation therapy, which is crucial for personalizing cancer treatment and minimizing toxicity.

Recent genome-wide studies have provided insights into the genetic factors that contribute to variations in radiotoxicity, helping to improve the safety and effectiveness of radiotherapy for cancer patients.

Genetics and genomics of radiotherapy toxicity: towards prediction. West, CM., Barnett, GC.[2022]

Recent advancements in radiation therapy have significantly improved disease control and quality of life for patients with solid tumors, but treatment decisions still largely rely on clinical and histopathologic factors rather than genetic information.

There is a growing opportunity to integrate genomic techniques into radiation oncology, which could lead to the identification of biomarkers that help tailor radiation treatment plans, including dosage and the use of systemic therapies.

In a study of 42 patients with locally advanced breast cancer, the neoadjuvant chemoradiation therapy (NACRT) showed a pathologic complete response (pCR) rate of 38%, slightly higher than the 33% pCR rate observed with standard neoadjuvant chemotherapy (NACT).

Baseline factors such as hemoglobin levels of ≥13 g/dL and a body mass index of <26 were strongly associated with better responses to NACRT, indicating that these parameters could help personalize treatment for patients.

Recent advances in breast cancer molecular genetics can help identify which tumors are resistant to radiation therapy, potentially leading to more effective treatment strategies.

Understanding the genetic background of both patients and tumors may allow clinicians to better predict who will benefit from radiation therapy and who is at risk for long-term side effects, improving overall treatment outcomes.

In a study of 270 early-stage breast cancer patients, those with BRCA1/2 mutations experienced a higher rate of neutropenia (32%) after the first cycle of anthracycline-based chemotherapy compared to non-carriers (10%).

Non-carriers reported more severe nausea and vomiting (13% vs. 7%), while BRCA mutation carriers showed increased radiation toxicity, particularly after mastectomy and neoadjuvant chemotherapy.

A new model for genetic radiotherapy predicts a potential increase in tumor control probability (TCP) by up to 15% compared to traditional radiotherapy, using reasonable values for transduction fraction and enhancement factor.

The model suggests that with improved techniques, TCP could theoretically increase by nearly 70%, allowing for significant dose reductions in radiation therapy while maintaining tumor control.

In a study of 286 women with breast cancer, those with pathogenic variant (PV) mutations, including BRCA1/2 and non-BRCA1/2 mutations, showed similar oncologic outcomes and toxicity rates after receiving radiation therapy compared to patients without mutations.

The findings support the use of adjuvant radiation therapy as a standard treatment for breast cancer, regardless of the presence of germline mutations, as there were no significant differences in overall survival, locoregional recurrence, or disease-specific death among the groups.

The Adjuvant Radiotherapy Intensification Classifier (ARTIC), developed from a study of 748 patients, effectively predicts locoregional recurrence (LRR) risk and the benefit of radiotherapy (RT) after breast-conserving surgery, showing a significant hazard ratio of 3.4 for LRR in patients treated with RT.

Patients with low ARTIC scores experienced a substantial reduction in LRR risk with RT, while those with high scores showed less benefit, indicating that ARTIC can help tailor RT strategies for better outcomes in breast cancer treatment.

Radiogenomics aims to identify genetic variants that predict which cancer patients are at higher risk for adverse effects from radiotherapy, potentially improving treatment personalization.

A predictive assay based on single-nucleotide polymorphisms could help estimate the risk of radiation injuries, allowing for tailored therapies that enhance patients' quality of life.

In a study of 416 breast cancer patients, 27.6% experienced early adverse skin reactions (EASR) after radiation therapy, with significant associations found between EASR and specific genetic variations in five DNA damage repair genes: ATM, CHEK1, ERCC2, RAD51C, and TGFB1.

Nine specific single-nucleotide polymorphisms (SNPs) within these genes were identified as potential predictors of EASR, and a polygenic risk score model indicated that patients with higher genetic risk scores were significantly more likely to develop EASR, highlighting the importance of genetic factors in personalizing radiation therapy.

Radiation therapy (RT) is an effective treatment for various conditions, including Morbus Dupuytren, keloids, and desmoid tumors, with evidence supporting its use across multiple disorders.

The updated DEGRO guidelines classify the strength of evidence for RT's efficacy as ranging from level 2c to 4, indicating it can be a primary treatment or a valuable adjunct to other therapies.
