334PClinical outcome and toxicity data in patients with advanced breast cancer treated with cyclin-dependent kinase 4/6 (CDK4/6) inhibitors combined with endocrine therapy in a real-world clinical setting

ConclusionsAmong patients with HR-positive advanced breast cancer treated with CDK4/6i combined with endocrine, the estimated PFS was comparable to previously reported data. Treatment was well tolerated, with a low drug discontinuation rate.Legal entity responsible for the studyHellenic Cooperative Oncology Group.FundingHellenic Cooperative Oncology Group (HeCOG).DisclosureE.

A study led by UCLA researchers found that adding ribociclib, a targeted therapy drug, to standard hormone therapy significantly improves overall survival in postmenopausal women with advanced hormone-receptor positive/HER2- breast cancer, one of the most common types of the disease.The findings also show the combination treatment is beneficial at the time of recurrence and should become a first-line option in postmenopausal women with HR+/HER2- advanced breast cancer.The study was published today in the New England Journal of Medicine and presented earlier this year at the European Society for Medical Oncology Congress in...

AbstractBackgroundA high percentage of breast cancer patients in the Asia-Pacific ( ∼42%) and Middle East (∼50%) regions are aged 50 years or younger. Although a high proportion of younger patients with endocrine-responsive metastatic disease are treated initially with cytotoxic chemotherapy (CT) in routine general practice, data from phase III trials have shown higher response rates and longer progression-free survival with endocrine therapy (ET) in combination with CDK4/6 inhibitor versus single agent ET. Due to lack of direct evidence, trials in pre-/perimenopausal advanced breast cancer are thus necessary to as...

Abstract Endocrine therapy represents a mainstay adjuvant treatment of estrogen receptor-positive (ER+) breast cancer in clinical practice with an overall survival (OS) benefit. However, the emergence of resistance is inevitable over time and is present in one-third of the ER+ breast tumors. Several mechanisms of endocrine resistance in ER+/HER2- advanced breast cancers, through ERα itself, receptor tyrosine signaling, or cell cycle pathway, have been identified to be pivotal in endocrine therapy. The epigenetic alterations also contribute to ensuring tumor cells' escape from endocrine therapie...

CONCLUSION: Collectively, these findings suggest that while FGFR1 amplification confers broad resistance to ER, PI3K, and CDK4/6 inhibitors, TORC1 inhibitors might have a unique therapeutic role in the treatment of patients with ER+/FGFR1+ MBC. PMID: 31371343 [PubMed - as supplied by publisher]

A UCLA-led study has found that using a drug called ribociclib in combination with a common hormone therapy may help premenopausal women with the most common type of breast cancer live longer than if they only receive the hormone therapy.Ribociclib is considered a cyclin-dependent kinase inhibitor that works by blocking the activity of proteins called cyclin-dependent kinase 4/6 enzymes, which promote cell division and cancer growth.The study involved 672 women aged 25 to 59 when the study began who had advanced hormone-receptor positive/HER2- breast cancer. Seventy percent of the women who took the combination therapy wer...

In conclusion, our WGCNA analysis identified candidate prognostic biomarkers for further basic and clinical researches. Introduction Breast cancer is a frequently diagnosed malignancy and the leading cause of cancer death among females around the world, accounting for 24% of cancer diagnoses and 15% of cancer deaths in females. According to Global Cancer Statistics 2018, there will be nearly 2.1 million new cases diagnosed globally, with ~62 thousand deaths. The incident rates of breast cancer increased in most developing countries during last decades, resulting from a combination of social and economic factors, incl...

CONCLUSION: Several patients with clinicopathologic features like hormone receptor positivity and HER2 negativity can avoid chemotherapy even with lymph node metastasis. Future studies with a long-term follow-up and a larger number of patients are required for validating our results. PMID: 30833157 [PubMed - as supplied by publisher]

CONCLUSIONS: This study confirmed the therapeutic impact of lapatinib, trastuzumab, and paclitaxel therapy for each ER- and ER+ subgroup of HER2+ patients. Development of further strategies and tools is required, particularly for luminal HER2 disease. PMID: 29445928 [PubMed - as supplied by publisher]

Authors: Rugo HS, Li H, Gui X Abstract Breast cancer is one of the most prevalent cancers and the leading causes of cancer mortality in women worldwide and in China. For hormone receptor-positive (HR+) breast cancer, accounting for approximately 60-80% of breast cancer, endocrine therapy (ET) is the primary treatment strategy. For patients with HR+ metastatic breast cancer (MBC), there are many endocrine-based treatment options that can improve long-term outcomes and optimize quality of life. With the emergence and availability of new and effective agents, the options for ET have expanded in the last two decades. A...

AbstractPurposeWe investigated the oncologic outcomes by intrinsic subtype and age in young breast cancer patients and whether survival differences were related to treatment changes over time.MethodsA retrospective analysis was performed on 9633 invasive breast cancer patients treated at Asan Medical Center from January 1989 to December 2008. We also enrolled a matched cohort adjusting for tumor size, lymph node metastasis, subtypes, and tumor grade. Patients aged
