#Prosigna
Prosigna, a genomic test, determined that 68% of breast cancer patients w/ estrogen responsive HER2- breast cancers could forgo chemotherapy.

This test analyzed 50 genes & generates a Risk of Recurrence score.

Breast cancer is not one size fits all.
Another step towards personalized treatment.

Good news for many women with breast cancer. The Prosigna test is already approved in some centres. UK's NICE will review it next – expect broader NHS access in months. Prof. Justin Stebbing reports.

which accounts for up to 80% of breast cancer cases globally — across 6 countries. Those with a low score on a genomic test (Prosigna), which analyses activity of 50 genes in tumour tissue, could be safely treated with hormone therapy alone. The findings were presented at the ASCO annual meeting.

Gene expression was a breakthrough 20 years ago.

Despite academic ubiquity, only OncotypeDx, MammaPrint, and ProSigna actually improve breast cancer decisions.

Wrong data choice kills your model before training starts.

🔍 Why It Matters
☑️ 20% of HR+/HER2- EBC patients relapse despite adjuvant C-ET.
✅ Existing tools (e.g., 21-gene, 70-gene) guide chemo decisions but fail to pinpoint high-risk patients after C-ET.

DNA test may help many breast cancer patients over 40 avoid chemotherapy, study finds
An international clinical trial suggests that a significant proportion of breast cancer patients could safely avoid chemotherapy thanks to a new DNA-based test. The study, led by University College London (UCL), involved more than 4,000 newly diagnosed patients aged over 40 across the UK, Norway, Sweden, Australia, New Zealand and Thailand. Researchers used a genomic test known as Prosigna, which analyses the activity of 50 genes linked to breast cancer growth to estimate the risk of cancer returning. Based on the results, around two-thirds of participants were classified as low-risk and did not receive chemotherapy, instead being treated with hormone therapy alone. The outcomes showed that the five-year survival rate for patients who avoided chemotherapy was 93.7%, compared with 94.9% for those who did receive it, suggesting minimal difference in survival outcomes. This finding indicates that many patients may be exposed to the harsh side effects of chemotherapy unnecessarily. These side effects can include fatigue, nausea, hair loss, weakened immunity, and fertility complications, all of which significantly affect quality of life. The researchers also estimate that more than 5,000 NHS patients annually in the UK could potentially avoid chemotherapy if the approach is adopted more widely. Clinicians involved in the study argue that treatment decisions should increasingly be guided by tumour biology rather than traditional clinical indicators alone. However, it remains unclear whether the findings apply to patients under 40, with further research still required. Experts describe the results as a step towards more personalised and less invasive cancer treatment strategies.

Милиони пациенти с рак на гърдата могат да избегнат химиотерапия, сочат данни от ново изследване
Милиони пациенти с рак на гърдата може безопасно да избегнат химиотерапия благодарение на геномния тест Prosigna, съобщава BBC. Тестът помага на лекарите да преценят при кои пациенти химиотерапията би имала реална полза и при кои лечението може да продължи само с хормонална терапия. **Данните са от международно клинично проучване, ръководено от University College London. В него са участвали над 4000 пациенти над 40-годишна възраст, които наскоро са получили диагноза рак на гърдата.** Според резултатите повече от две трети от участниците в проучването са могли да избегнат химиотерапията и страничните ѝ ефекти. Те включват умора, гадене, косопад, отслабване на имунната система и репродуктивни проблеми. Пациентите в проучването са от Великобритания, Норвегия, Швеция, Австралия, Нова Зеландия и Тайланд. Геномният тест Prosigna измерва активността на 50 гена, свързани с развитието на рака на гърдата. На тази база той изчислява риска заболяването да се върне. Пациентите, при които тестът е отчел нисък риск болестта да се върне, са били около две трети от всички участници. Те не са преминали през химиотерапия. Пет години по-късно делът на пациентите, които са живи, е бил 93,7% в групата без химиотерапия и 94,9% при пациентите, чието лечение е включвало химиотерапия. Основното лечение при рак на гърдата обикновено е операция за отстраняване на тумора. След това често се препоръчва химиотерапия, за да се намали рискът болестта да се върне. Химиотерапия често се предлага и на хора с ранен стадий на рак на гърдата, когато заболяването вече е засегнало близките лимфни възли. **Според University College London лекарите се притесняват, че при част от пациентите с най-често срещания тип рак на гърдата това лечение носи малка полза.** От университета посочват, че в резултат на проучването над 5000 пациенти в британската здравна система годишно биха могли да избегнат химиотерапия. Резултатите от проучването ще бъдат представени днес на годишната среща на American Society of Clinical Oncology в Чикаго. Това е най-голямата конференция в света, посветена на онкологичните заболявания. Главният изследовател на проучването проф. Роб Стайн от UCL Cancer Institute казва, че данните са важна стъпка към по-персонализирано лечение. По думите му проучването показва, че решенията за терапия могат да се вземат според биологията на самия тумор, а не само според традиционните клинични показатели. „За пациентите това означава, че много от тях могат да бъдат пощадени от физическата и емоционалната тежест на химиотерапията и от възможните ѝ дългосрочни странични ефекти“, казва той. Според University College London все още не е ясно дали резултатите важат и за хора под 40-годишна възраст. Отговорът на този въпрос се очаква след няколко години.

Models without actions are useless.

"This subtype has worse survival" - so what? What drug? What treatment?
PAM50 breast cancer classifier was useless until ProSigna turned it into a score recommending chemotherapy.

Introduction: The integration of artificial intelligence (AI) and genomic analysis into oncology is transforming cancer diagnostics, with tests like Veracyte's Prosigna setting a new standard for personalized treatment. However, the digitization of highly sensitive genomic data introduces a complex threat landscape, requiring robust cybersecurity frameworks to prevent data breaches that could have catastrophic consequences for patient privacy and the integrity of healthcare research.
