Study Summary

This trial will compare the effects of omitting adjuvant ET versus standard of care in older patients with lower risk breast cancer.

Who is the study for?
This trial is for patients aged 70 or older with early-stage, lower-risk hormone receptor-positive breast cancer. They must be able to consent and fill out questionnaires in French or English, have a new diagnosis of certain types of breast carcinoma, and have undergone specific surgeries without metastatic cancer.Check my eligibility
What is being tested?
The study is testing the necessity of endocrine therapy (ET) after surgery in older patients with low-risk breast cancer. It randomly assigns participants to either receive ET or no ET post-surgery to see if omitting ET can still effectively manage their condition.See study design
What are the potential side effects?
Endocrine therapy may cause hot flashes, fatigue, mood swings, reduced sex drive, bone thinning (osteoporosis), joint pain, and an increased risk of blood clots.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the desired outcome of this clinical experiment?

"This clinical trial, which will be monitored for a period of two years after initiation, aims to achieve 90% patient recruitment. Secondary objectives include evaluating endocrine therapy related toxicity according to Common Terminology for Adverse Events version 5 (CTCAEv5), rate of treatment discontinuation and associated reasons why the endocrine therapy treatment was discontinued as well as health-related quality of life scores assessed by Cancer and Aging Research Group geriatric assessment tool (patient-tool) and Functional Assessment of Cancer Therapy - Endocrine Symptom Subscale (FACT-B plus ES)."

Answered by AI

What is the current recruitment rate for this research endeavor?

"Affirmative. The information available on clinicaltrials.gov demonstrates that this research initiative, initially posted on August 19th 2021, is actively recruiting participants at present. Specifically, 100 individuals are being sought from a single site for the trial's duration."

Answered by AI

What hazards, if any, are associated with No endocrine therapy?

"Based on our team's evaluation, the safety rating for No endocrine therapy is 3. This therapy has been approved after undergoing extensive clinical trials in Phase 4."

Answered by AI

Is there still availability for participants to join this research project?

"Affirmative. Data on clinicaltrials.gov confirms that this research, initially posted on August 19th 2021, is still looking for individuals to join the experiment. Specifically, 100 people need to be identified at 1 medical centre."
