The purpose of the study is to determine the feasibility of genomically guided radiation therapy (RT) in people with triple negative (HER2 negative, hormone receptor negative) breast cancer undergoing breast conservation therapy.
1,219 studies on the registry are indexed under Triple Negative Breast Neoplasms; 446 are open to participants now.
This study's planned enrollment of 86 is above the median of 60 across 1,053 interventional studies indexed under Triple Negative Breast Neoplasms.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Karnofsky performance status (KPS)

Participants will be assigned to optimized arm based on their RSI score. Participants will receive whole breast radiation therapy with or without regional lymph node irradiation as appropriate with or without a boost to the lumpectomy cavity.
Radiation: Genomically Guided Radiation Therapy
Participants will receive standard of care whole breast radiation therapy with or without regional lymph node irradiation as appropriate with a boost to the lumpectomy cavity.
Radiation: Genomically Guided Radiation Therapy
Participants will receive treatment 5 days per week, in once daily fractions. The total dose will be 50 Gy in 25 fractions or 42.56 Gy in 16 fractions with or without a boost of 10 Gy in 5 fractions to the cavity.

Local Control
Local control will be defined as lack of progression in the ipsilateral breast as documented by response assessment imaging
Time frame: At 3 Years
Overall Survival (OS)
OS will be measured from the date of study initiation to the date of death due to any cause.
Time frame: Up to 5 Years
Progression Free Survival (PFS)
PFS is measured from the date of first treatment to the date of first observation of PD or death due to any cause.
Time frame: Up to 5 years
Distant Control
Distant control will be defined by lack of progression outside the irradiated treatment field
Time frame: Up to 5 Years
Quality of Life following Genomically Guided Dose Personalization
Quality of life (QOL) will be assessed through the completion of the Functional Assessment of Cancer Therapy for Breast Cancer questionnaire (FACT-B). This quality of life questionnaire contains questions from the FACT-General (G) questionnaire in the domains of physical, social/family, emotional, and functional well-being as well as additional questions pertaining to patients with breast cancer. The questionnaire will be completed at screening, during protocol therapy and at follow-up visits
Time frame: Up to 5 Years
