ClinConnect Summary

This clinical trial is designed to study how effective and safe a specific cancer treatment, called anti-HER2 therapy, is for Nigerian women with a type of breast cancer known as HER2-positive breast cancer. The researchers want to find out how this treatment works both before and after surgery to help improve care for patients with this condition.

To be eligible for the trial, women must be between 18 and 70 years old and have a breast tumor that is at least 2 centimeters in size. They must also have a confirmed diagnosis of HER2-positive breast cancer and have not received any prior chemotherapy for this type of cancer. Participants will need to undergo some tests to ensure their overall health, and they will be asked to provide written consent to join the study. If selected, participants can expect to receive anti-HER2 therapy and regular follow-up throughout the study to monitor their progress and any side effects. It’s important to note that this trial is not yet recruiting, so women interested in participating should keep an eye out for updates.
