Gambaran histopatologi kanker payudara Periode Januari 2012 – Desember 2012

Cancer is a class of diseases characterized by uncontrolled cell division and the ability of these cells to invade other biological tissues, either by direct growth in adjacent tissue (invasion) or by migration of cells to distant sites (metastasis). There are several methods that can be used in diagnosis of cancer. But until now, the gold standard to diagnosis of cancer is histopathological examination. The examination can determine the type of both malignant and benign cancers. Currently, breast cancer is one of the most prevalent cancers in worldwide, and became the highest cause of death from the other cancers. That is why the research was conducted in order to find out an overview of breast cancer histopathology. This research is a descriptive retrospective survey method through data collection, analysis, and evaluation of the amount of histopathological examination of breast cancer patients in the Anatomical Pathology Laboratory Manado period January 2012- December 2012. Data collected through the analysis of 163 medical records description of breast cancer histopathological period of January 2012- December 2012 were selected from a total sampling methods. These results indicate that the description of breast cancer histopathology most commonly found in the Anatomical Pathology Laboratory Manado period January 2012- December 2012 were fibroadenomas were 62 cases ( 38.1 % ) and ductal invasive carcinoma followed by 49 cases ( 30.1 % ). Most women and the most common age group 40-49 years.

Ada beberapa metode yang dapat digunakan dalam mendiagnosis kanker. Tetapi sampai sekarang yang menjadi gold standard dalam mendiagnosis kanker adalah pemeriksaan histopatologi. Dimana dalam pemeriksaan ini dapat menentukan jenis kanker baik ganas maupun jinak. Saat ini kanker payudara merupakan salah satu kanker yang paling banyak dijumpai diseluruh dunia, dan menjadi penyebab kematian tertinggi akibat kanker. Maka dari itulah penelitian ini dilakukan guna untuk mencari tahu gambaran histopatologi kanker payudara. Penelitian ini merupakan penelitian bersifat deskriptif dengan metode survey retrospektif melalui pengumpulan data, analisis, dan evaluasi jumlah hasil pemeriksaan histopatologi penderita kanker payudara di Laboratorium Patologi Anatomi Manado periode januari 2012-desember 2012. Pengumpulan data dilakukan melalui analisis pada 163 data rekam medis dari gambaran histopatologi kanker payudara periode januari 2012-desember 2012 yang dipilih dari metode total sampling. Hasil penelitian ini menunjukan bahwa gambaran histopatologi kanker payudara yang paling banyak ditemukan di Laboratorium Patologi Anatomi Manado periode januari 2012-desember 2012 adalah fibroadenoma sebanyak 62 kasus (38.1%) dan diikuti duktal karsinoma invasif sebanyak 49 kasus (30.1%). Terbanyak pada perempuan dan umur tersering golongan 40-49 tahun.

Peritoneal metastases in breast cancer patients: Differences in survival depending on histological subtype

e12024 Background: Distant spread from breast cancer is commonly found in bones, lungs, liver, and central nervous system. Metastatic involvement of peritoneum and retroperitoneum is unusual and unexpected. The aim of the study was to perform a comprehensive analysis of breast cancer patients with peritoneal metastases and to compare survivals depending on biological subtypes. Methods: 44 breast cancer pts with peritoneal metastases were detected out of a database of 2,500 breast cancer patients treated in one institution between 1995 and 2005. Clinical characteristics such as estrogen receptor and progesterone receptor as well as survivals were analized based on breast cancer subtypes. Results: Mean patient age was 54 years, 25 patients (56%) had ductal invasive carcinoma while 19 (44%) were diagnosed lobular invasive carcinoma. 30 (68%) patients had endocrine responsive tumors. A HER-2 percentage is not provided due to the lack of data before the year 2000. Median survival calculated from peritoneal metastases in histologic subgroups was as follows: Median progression free survival was 36.5 months for ductal invasive carcinoma, and 23.5 months for lobular invasive breast cancer. Median overall survival was 46 (Std 38.5) months for ductal invasive breast cancer and 32 (Std 54.5) months for lobular invasive breast cancer. Conclusions: Patients with peritoneal metastases are a heterogenous group with a different outcome. The histologic subtype seems to be an important predictive factor as lobular invasive breast cancer is associated with worsened progression free an overall survival rates.

Schirrous invasive ductal carcinoma of the breast overexpress p53 oncoprotein

CONTEXT: Breast cancer is the most important neoplasm in adult women, and its worldwide incidence is growing. The tumoral stroma is very important for modulating the growth and invasion of the tumor itself. The relationship between these two components is not completely understood. Schirrous carcinoma is a variant of ductal invasive carcinoma in which the stroma is very desmoplastic, and the importance of this finding still a motive for debate in the literature. OBJECTIVE: To compare the desmoplastic reactions against biological markers, such as estrogen and progesterone receptors, oncoprotein c-erbB-2 and oncoprotein p53, with the objective of studying the relationship between the tumoral stroma and epithelial cancer cells. TYPE OF STUDY: Retrospective study. SETTING: Cancer Hospital A C Camargo and Faculty of Medicine of Ribeirão Preto, University of São Paulo, São Paulo, Brazil. SAMPLE: 107 adult women operated because of ductal invasive carcinoma. The cases were separated into 4 groups according to the desmoplastic reaction -- less than 15%, between 15-50%, 51-85%, and more than 85% fibrosis. The grade of fibrosis was determined by picrus-sirius staining and quantified by using a microscope with a stereo-imaging grid. Immunohistochemical methods were used to determine the expression of the hormonal receptors and c-erbB-2/p53 oncoprotein. MAIN MEASUREMENTS: Extent of desmoplastic reaction versus expression of estrogen and progesterone receptors, oncoprotein c-erbB-2, and oncoprotein p53. RESULTS: The results showed that schirrous carcinoma expresses oncoprotein p53 more frequently than other carcinomas with less extensive desmoplastic reaction. There were no differences between the grade of fibrosis and the other biological markers. CONCLUSION: The intense stromatous reaction in invasive ductal carcinoma may modulate the expression of p53. Further investigations should be made with the aim of understanding how this expression determines the proliferative activity in schirrous carcinoma, and whether this overexpression is secondary to mutation of the p53 gene or due to modulation of other molecules of the stroma.
