Abstract

Latar belakang Retinoblastoma merupakan keganasan mata tersering pada anak usia dibawah 5 tahun dan 50-60% kasus retinoblastoma di negara berkembang berakhir dengan kematian. Terapi saat ini sangat tergantung dengan stadium klinis dan walaupun telah diberikan terapi yang sesuai, masih ditemukan kasus rekurensi atau metastasis. Vitamin A diketahui banyak berperan untuk mata, dan telah terbukti pula vitamin A berperan pada karsinogenesis di beberapa keganasan lainnya. RAR alfa adalah reseptor dari retinoid acid yang salah satu fungsinya adalah sebagai anti proliferasi, sedangkan Ki-67 adalah petanda untuk menilai indeks proliferasi dari suatu sel. Tujuan penelitian ini dapat menilai adakah hubungan RAR dan Ki-67, berdasarkan diferensiasi dan stadium klinis pada retinoblastoma. Metode Penelitian ini dilakukan secara retrospektif dengan desain analisis korelasi terhadap 40 kasus retinoblastoma yang memenuhi kriteria penelitian, periode januari 2010-november 2014 di Departemen Patologi Anatomik RS Hasan Sadikin, Bandung. Seluruhnya dilakukan pulasan imunohistokimia RAR alfa dan Ki-67 dikorelasikan dengan stadium klinis dan diferensiasi sel. Hasil penelitian dianalisis statistik dengan uji Coefficient Contingensy dan kriteria Guillford. Hasil Hasil penelitian ini seluruhnya memberikan imunoekspresi positif pada RAR alfa dan Ki-67. Didapatkan imunoekspresi Ki-67 berkorelasi positif terhadap diferensiasi (p=0,042 dan R=0,370), namun tidak terdapat korelasi bermakna dengan stadium klinis, sedangkan pada pemeriksaan RAR alfa tidak terdapat korelasi bermakna baik dengan stadium klinis maupun tipe diferensiasi sel. Kesimpulan Tipe yang tidak berdiferensiasi menunjukkan indeks proliferasi yang lebih tinggi dibandingkan tipe yang berdiferensiasi. Kata kunci : diferensiasi, Ki-67, RAR alfa, retinoblastoma, stadium.

Abstract

Background: Data characteristics for renal cell carcinoma are mostly derived from developed countries. However, data from developing countries, specifically in Indonesia have not been fully described. This study aimed at describing renal cell carcinoma (RCC) characteristics based on age, gender, and histopathology type in Dr. Hasan Sadikin General Hospital Bandung.Methods: This was a descriptive study conducted in August–October 2015. The data were collected from histopathology medical records of patients who had been diagnosed with RCC at Department of Pathology Anatomy Dr. Hasan Sadikin General Hospital Bandung, from 2010 to 2014. Total sampling was used as sampling method. Only RCC records that had complete variables; which were age, gender, and histopathological type; included in this study.Results: There were 25 cases of renal cell carcinoma discovered in this study, 17 cases discovered in men and 8 cases discovered in women. The histopathology type found in this study was clear cell renal cell carcinoma (12 cases), papillary renal cell carcinoma (8 cases), chromophobe renal cell carcinoma (3 cases), and carcinoma of the collecting ducts of bellini (2 cases). There were no cases found below the age range 2–29 years old and above the age range 70–79 years old.Conclusions: Men have higher incidence than women with the ratio of 2:1. Peak incidence is found on the age range 50–59 years old. The most common histopathology type is clear cell renal cel carcinoma.[AMJ.2016;3(4):644–8] DOI: 10.15850/amj.v3n4.953

Abstract

ABSTRAK Latar belakang Epidermal growth factor receptor (EGFR) berperan dalam patogenesis dan progresivitas karsinoma kolorektal. Stadium Dukes menunjukkan luas penyebaran tumor dan digunakan sebagai pedoman terapi. Pada stadium Dukes A tumor masih terbatas pada tunika submukosa, stadium Dukes B tumor sudah menembus tunika muskularis dan stadium Dukes C sudah bermetastasis ke kelenjar getah bening. Penggunaan kemoterapi adjuvan pada stadium Dukes B masih kontroversi sehingga hanya diberikan pada stadium Dukes B yang high risk. Diperlukan penanda molekuler yang dapat menunjukkan tumor yang agresif. Pada penelitian ini akan diteliti hubungan imunoekspresi EGFR dengan stadium Dukes pada karsinoma kolorektal. EGFR diharapkan dapat digunakan menjadi penanda karsinoma kolorektal yang agresif. Metode Pewarnaan imunohistokimia EGFR dilakukan terhadap 45 blok parafin karsinoma kolorektal yang dilakukan kolektomi (masing-masing stadium Dukes A, B, C 15 kasus). Hasilnya dihubungkan dengan stadium Dukes. Hasil Pada stadium Dukes A sebanyak 2 kasus (13%) menunjukkan imunoekspresi positif dan stadium Dukes B sebanyak 8 kasus (53%) menunjukkan imunoekspresi positif dan pada stadium Dukes C sebanyak 11 kasus (73%) menunjukkan imunoekspresi positif. Imunoekspresi EGFR secara statistik (p=0.004, uji Chi-Square) lebih sering ditemukan pada stadium Dukes C. EGFR berperan penting dalam diferensiasi dan proliferasi sel. Pada sel normal pengaktifan sinyal EGFR menyebabkan proliferasi sel, migrasi, metastasis, penghindaran apoptosis dan angiogenesis. Kesimpulan Imunoekspresi EGFR lebih sering ditemukan pada stadium Dukes C dibanding Dukes A dan B. Kata kunci: EGFR, imunoekspresi, karsinoma kolorektal, stadium Dukes. ABSTRACT Background Epidermal growth factor receptor immunoexpression may clarify the effects of the pathogenesis and determine the prognosis of colorectal carcinoma (CRC). Dukes’ stage explained the extension of the tumor. Dukes’ stage A was defined as malignant tumour in which growth extends into the submucosa, but not into the muscle coat; Dukes’ stage B was defined as the tumour growth extends into the muscle coat; and Dukes’ stage C was defined as the presence of lymph node metastases. Adjuvant chemotherapy in Dukes’ stage B is controversial, which only given to high-risk Dukes’ stage B. Hence, we need to identify high-risk Dukes’ stage B. This research will study association EGFR clone H11 and CRC Dukes’ stage. Methods Immunohistochemistry was performed in paraffin-embedded specimens of 45 cases colorectal carcinoma (each Dukes’ stage A, B, C was 15 cases) for the assesment of clone H11 EGFR expression. The results were correlated with colorectal carcinoma Dukes’ stage. Results At Dukes’ stage A there were 2 cases (13%) showed positive immunoexpression and Dukes’ stage B there were 8 cases (53%) showed positive immunoexpression and Dukes’ stage C there were 11 cases (73%) showed positive immunoexpression. clone H11. EGFR clone H11 immunoexpression (p=0.004, Chi-Square test) was significantly more frequent in Dukes’ stage C. EGFR play an important role in cell differentiation and proliferation. The activation of EGFR signaling would lead to cell proliferation, migration, metastasis, evasion of apoptosis or angiogenesis. Conclusion EGFR immunoexpression was more frequent in colorectal carcinoma Dukes’ stage C explain clearly that EGFR play important role in pathogenesis colorectal carcinoma. Key words: colorectal carcinoma, Dukes’ stage, EGFR, immunoexpression.

Abstract

ABSTRACT Background: Most of cervical carcinoma patients, including cervical adenocarcinoma comes at an advanced stage and thus radiotherapy is one of the modality treatment. The success of radiotherapy depends on several prognostic factors such as the performance, staging, histopathology of tumor, presence of organ dysfunction and cellular biology marker such as VEGF. Activation singaling pathway Vascular Endothelial Growth Factor (VEGF) can induce radioresistance on cervical adenocarcinoma. Activation angiogenesis mediated by VEGF can be counted from microvessel density (MVD). Counting MVD use imunohistochemical CD34 on endothelial cells form capiller of blood vessel in peritumoral. The aim of this study was to determine correlation between immunohistochemistry VEGF dan MVD with neoadjuvant radiotherapy response cervical adenocarcinoma. Methods: This study was an observational study, cross-sectional and correlational analysis. Samples was collected by total sampling with amount 32 samples block parafin from Departement Anatomical Pathology General Hospital Dr. Hasan Sadikin Bandung and treated with complete neoadjuvant radiotherapy from Januari 2007 until December 2013. Immunohistochemical examination of VEGF and CD34 for counting MVD was done on all sample block parafin. Result: There was a strong correlation between microvessel density (MVD) with neoadjuvant radiotherapy response in cervical adenocarcinoma (p = 0.000). In this study MVD above 30 correlate with poor neoadjuvant radiotherapy response in cervical adenocarcinoma. Conclusion: Examination MVD recommended for cervical adenocarcinoma patient before radiation treatment.   Keyword : Cervical Adenocarcinoma, CD34, Neoadjuvant Radiotherapy, VEGF

Abstract

The most common malignancy of testis is seminoma with prognosis that is not always good because of high recurrence rate and death cases. Extracellular matrix metalloproteinase inducer (EMMPRIN) is a glycoprotein adhesion molecules which plays a role in tumor cell invasion and metastasis as evidenced by immunohistochemistry method in several types of tumor cells and tissue that shows the correlation to the clinical progessivity.This study was conducted by observational descriptive analytics with each seven cases of seminoma nonrecurrences and recurrences diagnosed histopathologically from Dr.Hasan Sadikin Hospital, Advent Hospital and St.Borromeus Hospital in Bandung. This study shows that immunoexpression of estrogen receptor beta is not higher in testicular seminoma recurrence compared with nonreccurence. There was no higher imunoexpression of EMMPRIN receptor on testicular seminoma recurrence compared with nonrecurrence; besides, there was no relationship between immunoexspression of estrogen receptor beta and EMMPRIN in testicular seminoma nonrecurrence and recurrence.In conclusion, immunoexpression estrogen receptor beta expressed in all testicular seminoma, so that the patient could be given an alternative therapy and immunoexspression EMMPRIN, cannot be used to predict a recurrence in patients with seminoma who has received complete therapy.                                                        Keywords: EMMPRIN, Estrogen Receptor Beta, Seminoma Testis nonrecurrence and recurrence

Abstract

Karsinoma prostat merupakan keganasan kedua terbanyak pada laki-laki dan merupakan penyebab kematian kelima diseluruh dunia. Faktor prognosis utama pada adenokarsinoma prostat adalah metastasis yang menyebabkan tingginya angka kematian. Keadaan ini disebabkan karena pada kasus adenokarsinoma prostat yang metastasis pilihan terapi belum mendapatkan hasil yang memuaskan karena terdapat faktor resisten terhadap terapi radiasi dan kemoterapi. CXCR4 dan MMP 9 merupakan petanda imunohistokimia yang berfungsi dalam proses migrasi, chemotaxis dan detachment yang memegang peranan terhadap terjadinya metastasis pada adenokarsinoma prostat. Tujuan penelitian ini adalah mencari hubungan imunoekspresi CXCR4 dan MMP 9 dengan metastasis pada adenokarsinoma prostat. Penelitian ini menggunakan desain potong lintang dan observasional analitik. Sampel diambil dari blok parafin yang tersedia di Departemen Patologi Anatomi RSUP Dr. Hasan Sadikin Bandung pada periode 2010-2016. Jumlah sampel sebanyak 52 sampel, dibagi menjadi 2 kelompok, yaitu kelompok metastasis 26 sampel dan kelompok non metastasis 26 sampel. Keseluruhan sampel dilakukan pulasan imunohistokimia CXCR4 dan MMP 9.Hasil penelitian ini menunjukkan bahwa 71% sampel mengekspresikan CXCR4 kuat dengan proporsi terbesar pada kelompok metastasis (nilai p=0,000) dan 56% sampel mengekspresikan MMP 9 lemah pada kelompok metastasis (nilai p=0,55).CXCR4 dapat digunakan sebagai faktor prediksi metastasis pada adenokarsinoma prostat.
