The biological behavior and prognosis of breast cancer is often unpredictable with a number of factors contributing to the outcome. Nottingham's Prognostic Factor (NPI) takes into account the tumor size, nodal status, and histological grade of tumor. The receptor status considers the hormone receptor and HER2 status. The aim of the study was to correlate the NPI score with the receptor status expression in Indian women with breast cancer. A total of 78 breast cancer patients who underwent upfront modified radical mastectomy were recruited. NPI score and receptor status assessment was done at histopathological examination of the specimen. Hormone receptor negative breast cancer tended to have a higher NPI score compared to hormone receptor positive patients. However, this difference did not achieve statistical significance. NPI score parameters except for the histological grade are a reflection of the duration or time span of the tumor. On the contrary, the receptor status is indicative of the tumor biology and not of its time duration. A scoring system which incorporates the three parameters of the NPI as well as the receptor status would be the best prognostic index as well as predictive regarding the choice of adjuvant therapy.

An integral part of management of breast cancer is the appropriate treatment of the involved lymph nodes. While axillary nodes are always assessed and managed by sentinel node biopsy or an axillary clearance, the extra-axillary nodes do not receive equivalent attention even though they may influence staging, treatment, and prognosis. The purpose of this study was to assess the extra-axillary nodes by Doppler ultrasonogram in 228 patients with breast cancer over an 8-year period from January 2012 to January 2020. It is a case series analysis to evaluate axillary and extra-axillary lymph node basins in newly diagnosed breast cancer patients using linear array transducer ultrasonogram. It was found that while patients with T1 and T2 lesions did not have extra-axillary nodal involvement, 12% of T3 lesions (102 patients) and 50% of T4 lesions (48 patients) exhibited extra-axillary node involvement. Among the extra-axillary sites, internal mammary nodes were most often involved (24 patients) followed by infra-clavicular (8 patients) and supra-clavicular (4 patients) sites. Clinical examination by palpation could detect only the supra-clavicular nodes but was false negative in all patients who had an internal mammary or infra-clavicular node detected on ultrasound. Failure to identify internal mammary, supra-clavicular, and infra-clavicular lymph nodes can result in erroneous understaging in breast cancer patients leading to inadequate treatment and worse than anticipated prognosis. Therefore, all breast cancer patients as part of their pre-treatment protocol should undergo focused ultrasonogram evaluation of their axillary as well as extra-axillary lymph nodes.

Evaluation of expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2/neu) receptor was carried out on 80 breast cancer patients before and after neoadjuvant chemotherapy (NAC). No differences in expression were noted in 89% with reference to ER, 95% with reference to PR, and 91% with reference to HER2/neu status. A change in receptor status from positive to negative was noted in 12% for ER, 5% for PR, and 21% for HER2/neu after NAC. A negative to positive shift was noted in 11% for ER, 4% for PR, and 4% for HER2/neu after NAC. The possible reasons ascribed for change in receptor status after NAC are as follows: (1) Selection of chemoresistant clones with different receptor expression after NAC. (2) Tumor heterogeneity with variable receptor expression in different areas. (3) Ovarian suppression during NAC leading to alteration in receptor expression. (4) Technical considerations such as staining techniques and intra-observer and inter-observer differences in IHC slide interpretation before and after NAC. [ABSTRACT FROM AUTHOR]

Triple negative breast cancer (TNBC) is characterized by absence of estrogen and progesterone receptors (ER and PR) expression and lack of amplification of HER2 gene expression. It accounts for 15-20% of all breast cancer worldwide. The aim of the study was to determine the prevalence of TNBC patients visiting Surgery Department of Banaras Hindu University and correlate various clinico-pathological parameters vis-a-vis non-TNBC patients. TNBC accounted for 64/196 (32.6%) of all breast cancer patients. TNBC patients presented at a younger age (49 versus 55 years) compared to non-TNBC patients. TNBC patients had a higher chance of lymph node involvement (84 versus 75%), more grade III lesions (64 versus 50%), higher chance of lympho-vascular invasion (62.5 versus 45.5%) compared to non-TNBC patients. On follow-up of 36 months, the incidence of locoregional recurrence was 26.5% and distant metastasis 17.2% among TNBC patients compared to 16.6 and 12% respectively for non-TNBC patients. None of the TNBC patients developed bone metastasis which was seen in 7 of the non-TNBC patients. Stage for stage TNBC tumors had a worse histological profile and higher incidence of locoregional and distant metastases compared to non-TNBC patients. Although the prevalence of TNBC in our study was three times higher than reported worldwide yet their biological behavior is by and large similar to those reported worldwide. [ABSTRACT FROM AUTHOR]
