The Cost

Background: Estimation of Estrogen Receptor (ER) Progesterone Receptor (PR) and Human Epidermal Growth Factor Receptor 2 (HER2) is mandatory for choosing treatment options and prognosis of breast cancer patients. This estimation can be done by Immunohistochemistry (IHC) and Fluoroscence In Situ Hybridization (FISH) test. As the tests are expensive many of our patients can’t afford to do it. But if we practice doing the test routinely the cost will be reduced and our patients will be benefited. So we underwent a primitive study on receptor status in breast cancer patients. Our goal was to encourage the surgeons to advice receptor status routinely and treat the patients accordingly as patients prognosis will be much more better if they are treated according to their receptor status.Methods: This was a retrospective observational study of 74 breast cancer patients in a private clinic. In this study we have shown their receptor status by IHC and the data were analyzed.Results: Among the 74 patients 32 were ER +ve PR +ve, 11 were ER +ve PR -ve, 02 were ER –ve PR +ve, 29 were ER -ve PR -ve. ER &/or PR positive patients will be more responsive to hormone therapy. 28 patients were HER2 +ve, 34 patients were HER2 –ve and 9 were equivocal. HER2 positive patients will be benefited from targeted therapy. Among the patients 11 were triple negative that means they have worst prognosis.Conclusion: As knowing the receptor status in breast cancer help us as a predictive, prognostic and therapeutic indicator, we must advice it routinely and take steps to make it cheaper and easily available.Chatt Maa Shi Hosp Med Coll J; Vol.16 (2); July 2017; Page 48-50

Background: The incidence of brain metastases (BM) in breast cancer patients has increased. Many retrospective analyses have shown that first-line treatment with trastuzumab prolongs survival in patients with HER2-positive BM. In contrast, the evidence for other therapies targeting HER2 for patients with BM is rare. Methods: The aim of this review is to update the reader about current systemic treatment options in patients with HER2-positive metastatic breast cancer with BM who had already received trastuzumab. A literature search was performed in the PubMed database in June 2016. 30 relevant reports concerning the efficacy of trastuzumab emtansine (T-DM1), lapatinib and its combination with other cytotoxic agents, pertuzumab and novel HER2-targeting substances were identified. Results: There is limited but promising evidence for the use of T-DM1 and pertuzumab in the treatment of BM. Up to now, most reported studies used lapatinib as treatment of HER2-positive breast cancer with BM, a treatment with only a modest effect and a high toxicity profile. The combination of lapatinib with cytotoxic agents seems to result in better response rates. Conclusion: Further prospective investigations are needed to investigate the efficacy of the established and novel HER2-targeting agents on BM in HER2-positive breast cancer patients.

163 Background: The National Comprehensive Cancer Network (NCCN) Guidelines represent a well-established standard of care for the treatment of HER2+ breast cancer patients. eviCore healthcare is a licensee of NCCN that uses the NCCN guidelines to support its proprietary chemotherapy management program. All regimens assigned NCCN Category of Evidence 1, 2A, or 2B are adherent treatments in the eviCore program. NCCN recommends many systemic treatment options for HER2+ breast cancer, and a limited group is designated by NCCN as “preferred” based on superior efficacy and/or safety. This study evaluated the frequency of NCCN-preferred regimen use by practicing oncologists in HER2+ breast cancer patients. Methods: Chemotherapy authorizations for all HER2+ breast cancer patients with ≥ 1 injectable drug from 4/1/2015-9/30/2016 for multiple payers were included; > 90% of authorizations occurred in United HealthCare members. Cases with incomplete data were excluded. 3685 fully evaluable cases were stratified by stage, ER/PR status, and NCCN-preferred vs. NCCN-recommended status. The frequency of NCCN-preferred regimen selection was calculated for each subgroup. Results: There were 2883 HER2+/ER+ and/or PR+ cases and 802 HER2+/ER-/PR- cases. The highest frequency of NCCN-preferred regimen use occurred in neoadjuvant chemotherapy for patients with Stage III HER2+/ER+ and/or PR+ disease, where 88% of 289 patients used an NCCN-preferred regimen. Metastatic HER2+ patients had a markedly lower rate of NCCN-preferred regimen use at 62% of 557 cases. Only 48% of 1096 patients with Stage I/II HER2+/ER+ and/or PR+ disease received NCCN-preferred regimens. Conclusions: Patients receiving neoadjuvant chemotherapy for HER2+ breast cancer receive NCCN-preferred regimens at significantly higher rates than patients receiving adjuvant chemotherapy or metastatic treatment. Less than half of patients receiving adjuvant chemotherapy are receiving NCCN-preferred regimens. Further study is needed to determine the reasons for low preferred regimen use and ways to optimize preferred regimen use in HER2+ breast cancer.

Overexpression of the human epidermal growth factor receptor (HER2) oncoprotein in breast cancer patients, is one of the biological characteristics of the disease that determines the choice of appropriate systemic treatment. We report the case of a 41-year-old woman, with relapsing HER2-positive breast cancer in cerebral and pulmonary cells. The patient underwent multimodal first Iine treatment including pertuzumab, trastuzumab and docetaxel and panencephalic radiotherapy with good response and progression-free survival for approximately 16 months. Subsequently, further to a encephalic progression of the disease, the patient was treated in second line with the combination lapatinib + capecitabine which induced further encephalic response and disease control for additional 20 months (Oncology).

Background: Breast cancer is the most commonly occurring cancer in women and the second most common cancer overall. Owing to a unique pattern of presentation in terms of clinical and biological features, finding their mutual association may be important and may help predict prognosis. HER2 (human epidermal growth factor receptor 2)/neu is one such important immunohistochemical factor that is considered to be more prevalent amongst Indians and therefore makes up for an emerging area for studies. The study aimed to assess the patients of breast carcinoma in terms of their HER2/neu statuses and find out their association with clinical parameters.Methods: This was a prospective comparative study conducted in department of surgery, Hamidia hospital, Bhopal, India, with a total duration of 1 year between November 2018 to September 2019 including a total of 98 consecutive in house breast carcinoma patients.Results: A total of 98 breast cancer patients were tested for HER-2/neu gene presence. Of these 25 (25.5%) samples tested positive and 73 (7.48%) tested negative. A comparison of the two groups revealed that none of the clinic-pathological factors tested were found to have a statistically significant association with the HER2/neu status.Conclusions: It appeared that there is no defining factor in terms of clinic-pathological presentation that helps to separate significantly HER-2/neu positive with HER-2/neu negative cases with breast cancer. Still, immune-histochemical marker analysis should be an integral part of the overall work up of the breast cancer patients because of its both prognostic and therapeutic application and significance.

The mechanism of action underlying trastuzumab (Herceptin) function is thought to be binding of the Fab region of trastuzumab to the extracellular domain of the human epidermal growth factor receptor (HER2) (1). The transcriptional responses that follow signals transduced after trastuzumab binding of HER2 are less well understood. We mined published microarray and multiplexed gene expression data (2-4) to understand in an unbiased fashion genes most differentially expressed in the primary tumors of breast cancer patients treated with trastuzumab. We observed significantly increased and differential expression of the protein tyrosine kinase 7, PTK7 (5-7).

Abstract Background: Targeted therapies have largely improved prognosis of human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Yet, disease can still progress rapidly for some patients in the first two years after diagnosis. Our study aimed to establish a nomogram model to predict the 2-year breast cancer-specific survival (BCSS) in early HER2-positive breast cancer patients. Methods: A total of 32,481 HER2-positive patients derived from Surveillance, Epidemiology, and End Results (SEER) database were included in the construction of nomogram. Concordance index (C-index) and calibration curve were used to evaluate the discrimination ability and predictive accuracy. We tested the model in 804 patients from Shanghai Jiao Tong University Breast Cancer Data Base (SJTU-BCDB). Results: Age, estrogen receptor (ER) status, progesterone receptor (PR) status, histologic type, T stage and N stage were selected to construct the nomogram according to multivariable analysis. The 2-year BCSS rate was 95% and 60% for patients at low risk (<8 points) and high risk (>13 points) respectively. The C-index of model derived from SEER database is 0.81 (95%CI 0.79-0.83). Sensitivity analysis was performed in patients after breast surgeries with the C-index of 0.81 (95%CI, 0.79-0.83). Validation in 804 patients from SJTU-BCDB showed respective C-index of 0.77 (95%CI, 0.62-0.92) in total population, 0.67 (95%CI 0.44-0.90) and 0.90 (95%CI 0.81-0.90) in patients who received anti-HER2 therapy or not. Discussion: The novel nomogram can predict the 2-year survival outcome in HER2-positive patients independent of receiving anti-HER2 therapy or not and allow clinicians to adjust therapeutic strategies for patients with higher risk.
