Single Circulating Blast in the Peripheral Blood Film in Normal Individuals and Patients of Non-neoplastic Haematological Disorders and Non-hematological Neoplasms/Disorders- A Study at a Tertiary Care Centre

Introduction: The blasts in the peripheral blood is usuallyassociated with a haematological disorder. Study aimed tosee if a single blast seen in a peripheral blood film of healthyindividuals and patients of non-neoplastic haematologicaldisorders and non-hematological neoplasms/disorders didhave any clinical significance.Material and Methods: The period of study was from 2014to 2018 conducted at a tertiary care hospital. The study wasdone exclusively on Peripheral Blood Films. The films werestained with Leishman stain. An occasional blast was detectedin some healthy subjects and patients of non-neoplastichaematological disorders and non-hematological neoplasms/disorders.Result: The routine smears were analyzed with caution afterthe first case of a patient of Iron Deficiency Anemia revealeda clear-cut Blast. In the period of 4 years from 2014 to 2018,a total of 23 cases of apparently normal individuals or patientswith non neoplastic haematological disorders and nonhematological neoplasms/disorders showed at least 1% on oneseparate occasion.Conclusion: A careful morphological examination in theperipheral smears of few normal individuals and individualswith non neoplastic haematological disorders and nonhematological neoplasms/disorders showed at least 1%Blast on one separate occasion. The cells were clear cutblasts with a large size, fine nuclear chromatin, one to twonucleoli with round to slightly irregular nuclear contours anda mild amount of pale agranular cytoplasm. On thoroughinvestigations of these individuals there was no evidence ofa neoplastic haematological disorder. Therefore a single blastin a peripheral blood seen in a healthy individuals or patientswith benign haematological disorder and non-neoplasticneoplasms/disorders may not always indicate a neoplasticprocess.

Assessment of Clinico-Morphological Patterns of Palpable Breast Lumps in Tripura.

Background : With growing awareness in the general population, especially about breast pathologies, a lady with a breast lump is one of the commonest presentations in outpatient departments. Clinical examination would be followed in most patients with a confirmatory diagnosis under the microscope. Aim : The aim of the study is to evaluate the clinico-morphological patterns of palpable breast lump in Tripura. Methods: This retrospective study was conducted from January 2010 to January 2015 in Tripura Medical College and Dr BRAM Teaching Hospital. Study included all diagnosed cases of female breast lump during the above mentioned period. Detailed clinical data including age, site, side, family history and histological reports were retrieved from the records section. Observation: A total number of 140 cases studied ranging from 18 years to 80 years having a mean age of 49 years. Most common age group was seen in 18-30 years for benign lesions and 40- 60 years for malignant lesions. The commonest type of benign lesion was Fibroadenoma with 58 cases (76.3%) and in malignant lesions Infiltrating duct carcinoma was the commonest type with 32 cases (50%), followed by medullary carcinoma with 16 cases (25%). The disease was found on the left side in 91 cases (65%) and on the right side in 48 cases (34.3%) and bilateral in 1 case (0.71%). In cases of malignancy TNM Staging was available in 32 cases. Majority of the cases were stage II,

Expression of JMJD2A in infiltrating duct carcinoma was markedly higher than fibroadenoma, and associated with expression of ARHI, p53 and ER in infiltrating duct carcinoma.

Jumonji Domain Containing 2A (JMJD2A) may be a cancer-associated gene involved in human breast cancer. With a view to investigating expression of JMJD2A in human breast cancer and benign lesion tissues as well as relationship between JMJD2A and tumor related proteins, histological and immunohistochemical analysis, Western blot and quantitative real-time PCR in infiltrating duct carcinoma and fibroadenoma for JMJD2A and immunohistochemical analysis and quantitative real-time PCR in infiltrating duct carcinoma for tumor related proteins (ARHI, p53, ER, PR and CerbB-2) were performed. Histological examination validated the clinical diagnosis. The JMJD2A positive rate of infiltrating duct carcinoma was significantly higher than fibroadenoma by immunohistochemical analysis. The mean optical density of JMJD2A in infiltrating duct carcinoma was higher than fibroadenoma by western blot. JMJD2A mRNA level in infiltrating duct carcinoma was higher than fibroadenoma by quantitative real-time PCR. Spearman correlation analysis revealed that the expression of JMJD2A was associated with ARHI, p53 and ER from immunohistochemical results respectively. Pearson correlation analysis revealed that the expression of JMJD2A was associated with ARHI, p53 and ER from quantitative real-time PCR results respectively. Expression of JMJD2A in infiltrating duct carcinoma was higher, and associated with ARHI, p53 and ER. The results may take JMJD2A as a potential diagnostic and therapeutic target in human breast cancer.

Comparison of Thallium-201 Scan and Tc-99m Sestamibi Scan in the Differential Diagnosis of Breast Mass / 대한핵의학회잡지

PURPOSE: We performed this study to compare T1-201 and Tc-99m MIBI scans for the differentiation of malignant from benign breast mass. MATERIALS AND METHODS: Thirty-eight female patients underwent T1-201 breast scan and thirty-two of them also underwent Tc-99m MIBI scan of the breast. After intravenous injection of 74-111 MBq of T1-201, early (10 minutes) and delayed (3 hours) images were obtained. Then, 555-740 MBq of Tc-99m MIBI was injected and images after 30 minutes were obtained. We compared T1-201 and Tc-99m MIBI scans with pathologic RESULTS. RESULTS: Twenty-three patients were confirmed to have infiltrating duct carcinoma and fifteen patients to have benign breast mass by excisonal biopsy. The sensitivity of early and delayed T1-201 scan and Tc-99m MIBI scan in the detection of malignant breast lesion were 100% (23/23), 82% (18/22), and 90% (18/20), respectively. The specificity of early T1-201 scan was significantly higher than that of delayed T1-201 scan (p<0.05). The specificity of early and delayed T1-201 scan and Tc-99m MIBI scan were 73% (11/15), 73% (11/15) and 83% (10/12), respectively (p:not significant). Three patients out of nine with fibroadenoma and one patient with atypical duct hyperplasia were false positive in both early and delayed T1-201 scans. The size of fibroadenoma with false positvie in early and delayed T1-201 scan (4 cases) was larger than that of 11 fibradenoma with true negative scan (p<0.01). Metastatic axillary lymph node involvement was present in fifteen patients. The sensitive to detect metastatic nodes was 38% (5/13) for early T1-201 images, 15% (2/13) for delayed T1-201 images, 58% (7/12) for Tc-99m MIBI planar images and 67% (4/6) for Tc-99m MIBI SPECT. The sensitive of Tc-99m MIBI planar or SPECT was significantly higher than that of delayed T1-201 images (p<0.05). CONCLUSION: Early T1-201 and Tc-99m MIBI scan are useful noninvasive methods to differentiate malignant form benign mass of breast. Tc-99m MIBI scan was sensitive in detecting axillary lymph node metastasis in patients with brease cancer.

Immunohistochemical Analysis of TGF-beta Expression and Angiogenesis in Infiltrating Duct Carcinoma of the Breast

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.
