A retrospective analysis of bone tumors and tumor like lesions: a hospital based study of 76 cases

Background: Globally Bone tumors constitute 0.5% of the total World Cancer Incidence. In addition to benign and malignant bone tumors there are a number of nonneoplastic lesions that present in a manner similar to neoplastic conditions. Relevant demographic features such as age, sex and skeletal site are important to come to a conclusive diagnosis. The present study aims to show the prevalence and demography of bone tumors and tumor like lesions.Methods: A total of 76 cases of Bone Tumors and Tumor like Lesions were studied. They were reviewed and analyzed for age, gender, site of tumor and histologic types. Classification was done according to WHO histologic Classification of Bone Tumors.Results: There were 49 cases of primary bone tumors and tumor Like lesions with a median age of 22 years and 27 cases of metastatic bone tumors with a median age of 56 years. Males are more commonly affected. Osteosarcomas and Chondrosarcomas are the most common primary malignant Bone Tumors.Conclusions: Metastatic bone tumors constitute the highest number of bone tumors occurring at an older age group. Maximum numbers of bone tumors are found in the age range 11-20 years and all are primary bone tumor and tumor like lesions

Extensive intraductal component positive carcinoma of breast: two year study with special reference to ER/PR/HER2NEU/Ki67 in a tertiary care centre of Barak Valley

Background: Extensive intraductal component positive carcinoma (EICPC) of breast is defined by Schnitt et al as-A. 25% or more of Ductal carcinoma in situ (DCIS) is present along the invasive lesion and DCIS is also present outside the area of invasive carcinoma. B. EICPC also include carcinomas in which DCIS is associated with a “small” (approximately 10 mm or less) invasive carcinoma or carcinomas. In Extensive Intraductal Carcinoma (EIDC) most of the cases were associated with recurrence when surgical margin status is not evaluated or focally involved. Our objective was to study the prevalence of EIDC and expression of estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor (HER2NEU)/Ki67(antigen identified by monoclonal antibody KI67) in those cases.Methods: It was a retrospective cross sectional study conducted over a period of 2017 to August 2019.All the histologically confirmed cases of EIDC was retrieved from the institute.Results: Out of 65 cases of invasive carcinoma 17 (26.1%) cases were positive for EICPC. Age of patients ranged from 27 to 73years with mean age of 43 years and 5 patients (29.4%) were postmenopausal. Most of the cases  i.e. 6(35.2%) had a ER+/PR+/HER2NEU- status with most of the cases having high 6(47%)Ki-67 index. According to the BLOOM RICHARDSON GRADING 14 cases were grade II (82.3%) and 3 cases were grade I (17.7%) and in pT and pN staging majority were stage pT1 - 7 (41.1%). Most of the cases were mastectomy cases 11 (64.4%) with a base free status except in one lumpectomy case where margin was involved.Conclusions: In this study majority of the cases were ER+//PR+/HER2NEU- with most of the cases having high Ki67 index. Evaluation of EIDC, along with the negative margin status is important to prevent recurrence

A study on correlation of histopathological grade with hormone receptor and HER2/neu status in invasive breast carcinoma at a tertiary care centre of Barak valley

Background: Breast carcinoma is the most common malignancy occurring in females worldwide while in India it is the 2nd most common malignancy occurring after cervical cancer in females. The treatment modalities and prognosis of breast carcinoma depend largely on their hormone receptors (estrogen and progesterone receptors) and human epidermal growth factor receptor 2 (HER2/neu) status. The aim of this study was to correlate the receptor status in invasive breast carcinoma with histopathological grading of the tumor.Methods: This is a retrospective study carried out in the department of pathology, Silchar medical college and hospital, Cachar from January 2019 to December 2020. A total of 69 cases were considered for the study, selected on the basis of inclusion and exclusion criteria. Histomorphology grading in invasive ductal breast carcinomas was done along with the status of estrogen receptor (ER), progesterone receptor (PR) and HER2/neu.Results: The present study comprised of total of 69 infiltrating breast carcinoma cases. Out of all 51% cases were found to be in 4th decade of life. The most common type found in the study was invasive ductal carcinoma (not otherwise specified) seen in 86.96% cases. Maximum 41.67% of cases were histologically classified as grade III. A positive correlation was found between histological grading and immunohistochemistry of hormone receptors (ER, PR) and HER2/neu status.Conclusions: From the present study, it can be concluded that there is a positive correlation between histopathological grade and hormone receptors status and HER2/neu.The estrogen receptor and progestrone receptor were found negative in high grade disease on histological evaluation. Triple negative breast carcinomas have poorer prognosis as they tend to be of high grade

The Premium of Hilsa Sanctuary: A Socio-Economic and Ecological Evaluation from the Meghna Estuary, Bangladesh

Sanctuaries are widely regarded as a protected area where fishing has been placed under some restrictions by local, state, regional and national authorities for the conservation and management of fisheries resources. These sanctuaries have a broad array of positive and negative social, economic, cultural and political impacts on fishers. This study aims to analyze the socio-economic and ecological benefits and costs of hilsa sanctuaries to protect single most important hilsa species using Sustainable Livelihood Approach (SLA). Under the Protection and Conservation of Fish Act of 1950, six sites along the Padma, Meghna, Tetulia, and Andharmanik rivers have been designated as hilsa sanctuaries. Findings of the current study revealed that most fishers perceived production of hilsa and other species were increased as a direct consequences of sanctuaries establishment. However, a considerable proportion of hilsa fishermen was found to have low socioeconomic capital, as measured by monthly income, housing circumstances and asset ownership. During the restricted fishing season in the sanctuaries, these households are particularly vulnerable to food insecurity. The government’s compensation scheme is a good example of payment of ecosystem services in an open water fishery; however, this scheme does not include all the affected fishers. It is found that hilsa sanctuaries lead to income loss of the poor fishers which is insufficiently compensated by government support program. To compensate income loss, fishers resort illegal fishing which undermine the success of sanctuary. If the sanctuaries are to function effectively, affecting fishers must be addressed by offering enough compensation schemes so that fishers are able to support their families. Moreover, some fishers believed that a co-management approach involving fishers and government is the possible best management option for operating sanctuaries in a sustainable way
