Title: Advances in Targeted Therapy for Early-Stage Breast Cancer
Introduction:
Breast cancer is a prevalent disease affecting a significant number of women worldwide. In recent years, researchers have made significant progress in developing targeted therapies that effectively combat specific types of breast cancer. A new study presented at the 2023 American Society of Clinical Oncology Annual Meeting highlights the efficacy of ribociclib, a CDK4/6 inhibitor, in combination with hormone therapy for women with early-stage hormone receptor-positive/HER2-negative breast cancer.
Exploring the Study Findings:
The study involved approximately 5,000 patients with stage IIA, IIB, or III hormone receptor-positive/HER2-negative breast cancer. The patients were randomly assigned to receive either ribociclib with hormone therapy or hormone therapy alone. The findings revealed that patients who received ribociclib alongside standard hormone therapy experienced an extended period of being symptom-free after their initial cancer treatment. Furthermore, the addition of ribociclib reduced the risk of cancer recurrence by 25%.
Improved Cancer Remission Rates:
The study also assessed the long-term effects of ribociclib treatment. Patients followed for approximately 34 months showed an overall 3-year cancer remission rate of around 90% for those who received the combination therapy, compared to just over 87% for those on hormone therapy alone. These benefits were consistent across various subgroups of patients, indicating the broad potential of ribociclib as a treatment option.
Enhanced Patient Survival and Improved Quality of Life:
Patients treated with ribociclib not only experienced improved cancer remission rates but also showed better overall survival and a longer duration without signs and symptoms of cancer. The addition of ribociclib to endocrine therapy after surgery has the potential to decrease the risk of recurrence and improve survival. This new treatment option provides hope for patients with hormone receptor-positive/HER2-negative breast cancer, allowing them to make informed decisions about their treatment based on individual factors such as side effect profiles and the required length of treatment.
A New Dimension in Breast Cancer Treatment:
The successful use of ribociclib and other CDK4/6 inhibitors in treating advanced or metastatic breast cancer has paved the way for their potential application in early-stage breast cancer. Targeting specific genes that contribute to the growth of cancer cells has proven effective in controlling the disease and prolonging symptom-free periods. This breakthrough opens up new avenues for research and introduces a higher level of precision in breast cancer treatment.
The Importance of Follow-up and Further Evaluation:
While the study data regarding overall survival trends are promising, longer follow-up and more extensive evaluation are needed to fully assess the impact of ribociclib on patient outcomes. Continued research and follow-up studies will provide a clearer understanding of how these targeted therapies can contribute to long-term remission and improved survival rates.
Summary:
A new study presented at the 2023 American Society of Clinical Oncology Annual Meeting showcases the benefits of combining ribociclib, a CDK4/6 inhibitor, with hormone therapy for women with early-stage hormone receptor-positive/HER2-negative breast cancer. The research demonstrates that the addition of ribociclib to standard hormone therapy contributes to longer symptom-free periods post-treatment and reduces the risk of cancer recurrence by 25%. The study also highlights improved cancer remission rates, enhanced overall survival, and a longer duration without signs and symptoms of cancer for patients receiving ribociclib. This breakthrough in targeted therapy provides hope for patients and a potential new treatment option for healthcare professionals to consider.

June 15, 2023 – A drug that targets specific genes that help cancer cells thrive, when combined with hormone therapy, may help women with a specific type of early-stage breast cancer, according to a new research.
The targeted therapy drug showed success in women with early-stage hormone receptor-positive/HER2-negative breast cancer, according to research presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting. The study showed that patients who received the drug ribociclib (Kisqali) along with standard hormone therapy were symptom-free for longer after their first cancer treatment, compared with those who received hormone therapy alone.
Also, adding the drug to hormone therapy lowered the risk of the cancer coming back by 25%. Hormone receptor-positive/HER2-negative breast cancer accounts for approximately 65% to 70% of breast cancer cases in the United States, making it the most common subtype.
“The goal of treating early breast cancer is curative, with the hope that patients receiving curative therapy will not have recurrences,” said Dennis Slamon, MD, director of clinical and translational research at the UCLA Comprehensive Cancer Center, who presented the findings at the meeting. “But we know that even with stage II disease, a third of those patients recur, and in stage III disease, more than half recur even 2 to 3 decades later.”
Ribociclib is what is known as a CDK4/6 inhibitor, a drug designed to stop the growth of cancer cells. The FDA has approved it to treat HR-positive, HER2-negative advanced or metastatic breast cancer in premenopausal women along with another drug called an aromatase inhibitor, which is used to lower estrogen levels, or with another drug called an aromatase inhibitor. fulvestrant in postmenopausal women. .
Researchers randomly assigned about 5,000 people with stage IIA, IIB, or III HR-positive, HER2-negative breast cancer who were at risk of their cancer coming back to receive treatment with ribociclib with hormone therapy (2,549 patients) or therapy hormonal alone (2,552 patients).
Over time, the cancer came back in 189 patients in the ribociclib group (7.4% of patients), compared with 237 who used hormone therapy alone (9.2% of patients).
Patients were followed for approximately 34 months, with 20% completing 3 years of treatment with ribociclib and 57% completing 2 years of treatment.
The 3-year cancer remission rates were around 90% for patients who received combination therapy, compared with just over 87% for those treated with hormone therapy alone. The benefits observed in the ribociclib group were generally consistent in other subgroups of patients.
Ribociclib also showed better results in overall survival and time without signs and symptoms of cancer in the long term.
“Patients with [this type of cancer] now they have a new treatment option,” said Sylvia Adams, MD, a medical oncologist and director of the Breast Cancer Center at New York University Langone Perlmutter Cancer Center. “Adding … ribociclib to endocrine therapy after surgery may decrease the risk of recurrence and improve survival.”
Adams, who was not involved in the study, said there is another CDK4/6 inhibitor, abemaciclib, that is FDA-approved for use in conjunction with hormone therapy. “Now we will have a second option, once ribociclib is approved for this indication, and we can decide with patients which of these two drugs to use based on their side effect profiles and/or length of treatment,” she said.
Slamon explained that for overall survival, the “trend is in the right direction,” but longer follow-up is needed to see if ribociclib will make a difference.
