CONCLUSIONS: Adjuvant trastuzumab has substantially improved the survival of patients with HER2+ eBC, contributing over 41,000 LYG to Spanish society (over 36,000 DFLYG) in a cost-effective manner. However, the sum of LYG with trastuzumab is still far from the LY estimated for the general population, supporting the need of further advances in HER2+ eBC. PMID: 31303965 [PubMed]

AbstractPurposeLimited evidence exists on the impact of hormone receptor (HR) status to counsel HER2-positive early breast cancer patients receiving adjuvant anti-HER2 therapy.MethodsALTTO (BIG 2-06) was an international, intergroup, open-label, randomized phase III trial in HER2-positive early breast cancer patients randomized to receive 1  year of trastuzumab and/or lapatinib. HER2, estrogen and progesterone receptors were centrally tested for all patients. We investigated the impact of HR status on prognosis, risk of disease-free survival (DFS) events over time, patterns of first DFS events, and factors associated ...

Conclusions: A relevant number of patients required dose reduction but dose-reduced chemotherapy was tolerated well. Anthracycline-based regimens were used in patients who had not received adjuvant chemotherapy. Capecitabine required the most dose reductions. Taxanes were generally started at reduced doses, resulting in fewer grade 3+ toxicities. As well as age, underlying physiological reserve, current performance status and co-morbidities should guide physicians who should consider lower starting doses in OA and recognise that dose reductions may be required to improve tolerability. The PFS of all regimens were similar i...

Authors: Jang Y, Cho EY, Cho SY Abstract Mucinous carcinoma (MC) is a rare subtype of breast cancer, which is composed of tumor cells floating in the abundant extracellular mucin. This form of cancer is usually estrogen receptor/progesterone receptor positive and human epidermal growth factor receptor 2 (HER2) negative. Here, we present a case of HER2-positive MC with an unusual signet ring cell differentiation. It is very rare that a breast tumor consists entirely of signet ring cells. The tumor showed pathologic complete response (pCR) after neoadjuvant chemotherapy with trastuzumab and pertuzumab. pCR of HER2-po...

Conclusion: The RSS is comparable to the AJCC8 PS for a patient population receiving chemotherapy as well as endocrine- and HER2-targeted therapy and further stratifies stage IV patients. PMID: 31281728 [PubMed]
