ImmunoGen, Inc. Announces FDA Approval Of Kadcyla (Ado-Trastuzumab Emtansine; Also Known As T-DM1)
ImmunoGen, Inc ., a biotechnology company that develops anticancer therapeutics using its TAP technology, recently announced that Roche has reported that the U.S. Food and Drug Administration (FDA) has granted marketing approval to Kadcyla for the treatment of people with HER2-positive metastatic breast cancer who have received prior treatment with Herceptin (trastuzumab) and a taxane chemotherapy.
Condition: HER2-positive Early Breast Cancer Interventions: Drug: Pertuzumab IV; Drug: Trastuzumab IV; Drug: FDC of Pertuzumab and Trastuzumab SC; Drug: Doxorubicin; Drug: Cyclophosphamide; Drug: Docetaxel; Procedure: Surgery; Radiation: Post-Operative Radiotherapy; Drug: Hormone Therapy Sponsor: Hoffmann-La Roche Not yet recruiting
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]
Current evidence suggests that patients with Luminal A early breast cancer can skip chemotherapy or extended endocrine therapy, but immunohistochemistry-based biomarker analysis for St Gallen subtyping may not...
We present the case of a young, pregnant patient with metastatic BC with a complete clinical response to chemotherapy followed by surgical treatment. PMID: 31281427 [PubMed]
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]
Conclusions: The combination of 2 or 3 comorbidities significantly increases the incidence of symptomatic cancer treatment-related cardiotoxicity. Patients with bca experiencing cancer treatment-related cardiotoxicity who have a history of diabetes, dyslipidemia, and obesity might require more proactive strategies for prevention, detection, and treatment of cardiotoxicity while receiving trastuzumab-based treatment.

Conclusion: Administering adjuvant trastuzumab in a weekly cycle concurrently with anthracycline-taxane chemotherapy regimen appears to be a preferable option to optimize its favorable effect in improving DFS and to prevent significantly higher risk for cardiotoxic effects.
