Early breast cancer treatment evolution study
Part of Cancer, Skin clinical trials.
This study looks back at treatments given to people with triple-negative or HER2-positive early breast cancer between 2016 and 2021. It aims to understand how treatment approaches have changed over time.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You were diagnosed with early breast cancer (stages I, II, or III) between 2016 and 2021.
- You had chemotherapy or targeted therapy before surgery (neoadjuvant treatment).
- Your cancer was either triple-negative or HER2-positive.
- Your tumor has known hormone receptor (ER, PgR) and Ki67 status.
- You were 18 or older at the time of diagnosis.
- No cancer had spread to other parts of the body at diagnosis or within 3 months after breast surgery.

This study observes how doctors treat early breast cancer and what outcomes patients have. It's for people with hormone receptor-positive, HER2-negative breast cancer that hasn't spread to many lymph nodes.
This study looks at how breast cancer changes while you are receiving chemotherapy or targeted therapy before surgery. The goal is to better understand which treatments work best for different types of breast cancer.
This trial looks at different drug combinations given before surgery to shrink breast tumors. The goal is to find which treatments work best for different types of breast cancer, such as triple-negative, HER2-positive, or hormone-receptor-positive. If you are a woman scheduled for neoadjuvant therapy (treatment before surgery) and have not had previous cancer treatment, this study may be for you.
This Phase 2 study looks at how well early breast cancer shrinks with treatment and how that matches with what doctors find after surgery under the microscope. The goal is to learn better ways to predict and assess treatment success.
This study looks at whether some people with stage 1 HER2-positive or “triple-negative” breast cancer may safely need less (de-escalated) chemotherapy after surgery. The goal is to keep the cancer risk low while reducing treatment intensity, using special blood testing over time.
This study looks at different types of HER2-positive breast cancer to learn more about the disease. It is for people with early-stage or locally advanced breast cancer who have not yet received treatment, and aims to help doctors find better ways to personalize care.
