          Abstract

          Background:

          The adjuvant short course 9-week trastuzumab combination therapy for human epidermal receptor 2 positive breast cancer patients may often be considered as a cost-effective and safe option and has important implications for the Indian subcontinent as well as other developing countries. However, such regimens of shorter duration trastuzumab therapy like FinHer, offered in view of economic constraints, may not be able to achieve globally comparable cure rates in early breast cancer especially with high-risk women with more than 3 lymph node positive.

          Methods and Material:

          Outcome of 21 patients with HER2 positive breast cancer was treated with short course trastuzumab combination chemotherapy in the adjuvant setting was studied.

          Results:

          Out of 21 patients 15 are alive and disease free with a follow up of up to 73 months (median follow up 42 months).

          Estrogen, progesterone and HER2 receptor expression in breast tumors of patients, and their usage of HER2-targeted therapy, in a tertiary care centre in India.

          This study was undertaken to document the pattern of expression of estrogen (ER), progesterone (PR) and human epidermal growth factor receptor-2 (HER2) and the usage of HER2-targeted therapy in a large tertiary care hospital in India in the year 2008. The histopathology reports of all breast cancer patients registered in the hospital in 2008 were extracted from the electronic medical record system. All the cases were immunohistochemically evaluated for estrogen and progesterone receptor status (ER and PR), and c-erbB-2 protein (HER2) expression using standard immunoperoxidase method. The use of HER2-targeted therapies was evaluated by extracting relevant information from the database of the hospital pharmacy and case charts of patients enrolled in ongoing approved trials. A total of 2001 new patients of invasive breast cancers with available pathology reports were registered in the hospital in the year 2008. ER and/or PR expression was positive in tumors of 1025 (51.2%) patients. HER2 3+ expression by immunohistochemistry (IHC) was found in 335 (16.7%) and HER2 2+ in 163 (8.1%). The triple negative phenotype was found in 596 (29.8%) patients. An estimated 441 patients were eligible to receive HER2-targeted therapy based on their HER2 status. Of these 38 (8.6%) patients received some form of HER2-targeted therapy; 20 patients (4.5%) as part of ongoing clinical trials and 18 (4.1%) as part of routine care. The overwhelming majority of patients eligible for HER2-targeted therapy in our institution are unable to receive it because of financial constraints and limited access to health insurance. There is a higher fraction of patients with the triple negative phenotype compared to the Western population.

            ICON 2013: practical consensus recommendations for hormone receptor-positive Her2-negative advanced or metastatic breastcancer.

            The management of hormone receptor-positive Her2-negative breast cancer patients with advanced or metastatic disease is a common problem in India and other countries in this region. This expert group used data from published literature, practical experience, and opinion of a large group of academic oncologists, to arrive at practical consensus recommendations for use by the community oncologists.
