Survival outcome of adjuvant endocrine therapy alone for patients with lymph node-positive, hormone-responsive, HER2-negative breast cancer.

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]

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...

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...

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

Conclusions:ctDNA analysis identified PIK3CA mutations in pts with previously unknown or WT mutation status from archival tumor tissue; ORR and CBR were similar to those from archival tumor tissue suggesting that PIK3CA mutation testing from ctDNA may be used as a surrogate when tissue is unavailable. 21.7% of pts had mutations in both ESR1 and PIK3CA.Citation Format: Bundred N, Lavelle K, Sowerbutts AM, Pilling M, Todd C.

Background : The addition of anti-proliferative agents such new inhibitors of CDK4/6 to hormonotherapy have significantly improved the efficacy in patients with metastatic breast cancer (MBC). Oral vinorelbine provided the opportunity to give new schedules of chemotherapy with favourable tolerability and prolonged exposure. The present trial was designed to evaluate the clinical effects of the addition of oral vinorelbine to aromatase inhibitors in first line treatment for MBC.Methods : In this phase III, randomized, prospective, open trial named VICTORIANE (NCT02730091), postmenopausal women with HR+/HER2– with MBC ...

Background:Preclinical and clinical evidence suggest that cross-talk between HER2 and estrogen receptor signaling pathways in breast cancer (BC) contributes to treatment resistance (Kaufman et al. J Clin Oncol 2009; Arpino et al. J Natl Cancer Inst 2007). First-line pertuzumab (P), in addition to trastuzumab (H) + docetaxel (T), significantly improved progression-free survival (PFS) and overall survival (OS) compared with H + T in patients (pts) with HER2-positive metastatic BC (MBC) (Swain et al. N Engl J Med 2015; Baselga et al. N Engl J Med 2012). PERTAIN (NCT01491737) is the first study to assess first-line P + H + an ...

This study will test whether fulvestrant plus TAK-228, a dual TORC1/2 inhibitor, can overcome endocrine therapy resistance in ER-positive breast cancer. This is an open-label, randomized, 3-arm, phase 2 study of continuous once-daily TAK-228 (oral, 4 mg) or once-weekly TAK-228 (oral, 30 mg) plus fulvestrant (500 mg intramuscularly on d1 and d15 of cycle 1 [loading regimen] then d1 of each subsequent 28-d cycle), compared with fulvestrant alone, in pts with advanced or metastatic ER-positive/HER2-negative breast cancer that has progressed during/after AI therapy. Pts will be randomized 1:1:1 to the 3 arms and stratified at ...

Conclusions: Ki67 expression on CTCs is predictive of early relapse in patients with early BC. Ki67 expression is not decreased by adjuvant chemotherapy, whereas it is reduced early during follow-up, possibly due to adjuvant hormone therapy and/or anti-HER2 therapy. The above results suggest that additional therapy is needed for patients with early BC and Ki67(+) CTCs to prevent early disease recurrence.Citation Format: Sinn BV, Tsai T-H, Lau R, Fu C, Gould R, Murthy R, King TA, Hatzis C, Kwiatkowski DN, Valero V, Symmans WF.
