Abstract

Klasifikasi tumor sistem saraf pusat WHO terakhir didasarkan atas histogenesis tumor dan karakteristik molekuler genetik. Perubahan klasifikasi yang paling signifikan terjadi pada tumor glioma difus yang paling signifikan, yaitu katagori tumor secara garis besar berdasarkan status mutasi isocitrate dehydrogenase (IDH) 1 dan 2. Tulisan ini akan membahas tentang IDH1 dan IDH baik normal maupun mutan, hubungan mutasi IDH1 dan IDH2 dengan prognosis pasien, serta bagaimana penentuan status mutasi IDH1 dan IDH2 dalam diagnosis glioma.

Abstract

Tumor phyllodes adalah tumor bifasik yang memiliki karakteristik adanya dua lapis komponen sel epitel yang tersusun di dalam celah celah yang dikelilingi oleh komponen mesenkim hiperseluler yang tumbuh berlebihan yang selanjutnya akan membentuk struktur seperti daun. Tumor phyllodes dapat diklasifikasikan menjadi tiga varian yaitu tumor benign, borderline, dan malignant phyllodes. Penelitian ini dilakukan untuk mengetahui jumlah kasus dan karakteristik pasien varian tumor phyllodes payudara berdasarkan usia, manifestasi klinis dan ukuran tumor di RSUP Sanglah Denpasar pada periode tahun 2014-2018. Penelitian ini adalah penelitian deskriptif dengan desain cross-sectional. Data diambil dari arsip pemeriksaan histopatologi di Instalasi Laboratorium Patologi Anatomi RSUP Sanglah, Denpasar tahun 2014-2018. Terdapat 89 kasus tumor phyllodes yang ditemukan di RSUP Sanglah pada periode tahun 2014-2019 dengan proporsi varian yaitu 31 kasus (34,8%) tumor benign phyllodes, 34 kasus (38,2%) tumor borderline phyllodes, dan 24 kasus (27%) tumor malignant phyllodes. Rerata usia pasien pada varian tumor benign phyllodes, tumor borderline phyllodes, dan tumor malignant phyllodes adalah 41,3 tahun, 45,8 tahun dan 42,5 tahun. Manifestasi klinis yang paling sering ditemukan pada tumor phyllodes payudara di penelitian ini adalah adanya massa pada payudara pada semua varian. Rerata ukuran tumor pasien pada varian tumor benign phyllodes, tumor borderline phyllodes, dan tumor malignant phyllodes adalah 12 cm, 16,9 cm dan 21 cm.

Abstract

Introduction: Lung cancer found in young age is relatively rare with a percentage of cases only 1.4% of overall lung cancer cases in the world. Case: We reported two cases of lung adenocarcinoma in young women aged less than 30. The first case was lung adenosquamous carcinoma in a 28-year-old woman, a passive smoker, who had a family history of cancer. She had the mutation of epidermal growth factor receptor (EGFR) exon 19 deletion and received 1st generation of tyrosine kinase inhibitor. Since the patient was diagnosed at advanced stage with poor performance status, she died within 2 months after being diagnosed. The second case was lung adenocarcinoma in a 23-year-old woman. The patient was a passive smoker and had a history of cancer in the family. She was diagnosed at an advanced stage but with good performance status. The patient underwent chemotherapy with Pemetrexed-Platinum in 6 cycles and 15 cycles of radiotherapy. Conclusion: Lung cancer at a young age is more common in non-smoking female with the histopathology type adenocarcinoma. Non-specific early symptoms become a problem in the early enforcement of lung cancer at a young age. Many cancer-related issues occur in young cancer patient such as premature death, increased dependence on parents, difficulty in school and work due to medication, and reproductive disturbance.

Abstract

Background: Excessive exercise cause a deterioration of organ function and structure. Overtraining will cause reduce antioxidant reserve and excess free radical production. In this condition, there will be a decrease in the number of Leydig cells in the testis and followed by a decrease in testosterone level. Bali robusta coffee extract contains active compounds such as alkaloids, saponins, flavonoids, tannins and polyphenols. This study aims to prove whether Bali robusta coffee extract (Coffea canephora) can prevent a decrease in the number of Leydig cells and testosterone levels in male Wistar rats (Rattus norvegicus) with excessive physical training. Methods: Thirty-six rats were randomly divided into 2 groups: the control group (placebo aquabidest 2 ml) and the treatment group (Bali robusta coffee extract of 1 gram/kg BW). Both groups received excessive physical training in the form of swimming until the subjects experienced fatigue for 21-days. Results: The results showed that the mean of Leydig cell number in the treatment group was significantly higher, which was 3.70 ± 0.89 cell/field of view, compared to the control group, which was 2.92 ± 0.65 cell/field of view (p = 0.005). The mean testosterone level in the treatment group was also significantly higher, which was 6.32 ± 0.21 nmol/ml, compared to the control group, which was 1.95 ± 0.32 nmol/ml (p < 0.001). Conclusion: The administration of Bali robusta coffee extract (Coffea canephora) prevented a decrease in the number of Leydig cells and testosterone levels in male Wistar rats (Rattus norvegicus) with excessive physical training.

Abstract

Background: The main factor of skin aging is exposure to sunlight, especially UV B rays. Tamarind leaves extract known containing tannins, flavonoids, and polyphenols as anti-aging agents. This study was aimed to prove the protective effect of 3% Tamarind leaves (Tamarindus indica) ethanol extract cream in inhibiting the skin aging due to exposure to UV B by evaluate the tyrosinase expression and the amount of melanin. Methods: This was a randomized post-test only control group design involving 36 subjects of male Guinea pigs, that divided into 2 groups. The control group received placebo cream and the treatment group received 3% Tamarind leaves ethanol extract cream. Cream application was given twice a day for 2 weeks. UV B were given 3 times a week for 2 weeks with a total dose of 390 mJ/cm2. Tyrosinase expression was examined by calculating the cell percentage that express the enzyme using the immunohistochemical method. The amount of melanin was examined digitally by calculating the pixel percentage of melanin in Masson Fontana staining slides. Statistical analysis by the Independent T-test to compare the mean between two groups with p=0.05 significance. Results: The mean tyrosinase expression and the mean amount of melanin in the control group was higher than treatment group. 20.650±4.911% vs 16.067±3.451%, p=0.003 and 10.461±4.916 pixel% vs 7.300±3.111 pixel%, p=0.029, respectively. Conclusion: Administration of 3% Tamarind leaves (Tamarindus indica) etanol extract cream inhibited the increase in tyrosinase expression and the amount of skin melanin in male guinea pigs (Cavia porcellus) exposed to UV B.

Abstract

ABSTRAKEGFR memegang peranan penting dalam progresifitas dari KKR. P-Stage merupakan faktor prognosis independen pada KKR. Tujuan penelitian ini adalah untuk membuktikan adanya hubungan ekspresi EGFR dengan P-Stage pada karsinoma kolorektal tipe tidak spesifik di RSUP Sanglah Denpasar. Penelitian ini merupakan cross-sectional study, observasional analitik potong lintang. Sampel adalah penderita adenokarsinoma kolorektal tipe tidak spesifik yang telah dilakukan operasi dan pemeriksaan histopatologi di Laboratorium Patologi Anatomik RSUP Sanglah, Denpasar yang memenuhi kriteria inklusi dan eksklusi yang ditetapkan peneliti dengan besar sampel 46 pasien. P-Stage adalah sistem pengelompokan pasien yang dibuat berdasarkan penggabungan nilai dari 3 faktor prognosis yaitu umur pasien, derajat diferensiasi dan ukuran tumor, dikelompokkan menjadi P0 dan P1. Hasil penelitian dianalisis dengan analisis Chi square menganalisis hubungan antara ekspresi EGFR dengan P-Stage pada adenokarsinoma kolorektal tipe tidak spesifik di RSUP Sanglah Denpasar. Analisis uji rasio risiko prevalensi untuk mengetahui rasio risiko prevalensi dari ekspresi EGFR dengan P-stage. Nilai kemaknaan ditetapkan pada p<0,05. Hasil penelitian menunjukkan rentang usia 81 tahun, median 61,5 tahun dan rerata usia 61,98±9,824 tahun, kasus terbanyak pT3 (80,4%), derajat diferensiasi sedang (71,7%), lokasi tumor di kiri (45,7%), laki-laki (67,4%), P0 (67,4%) dan ekspresi EGFR positif (69,6%). Dari analisis chi-square didapatkan hubungan yang signifikan secara statistik antara ekspresi EGFR dengan P-Stage (p= 0,036). Pada analisis estimasi risiko didapatkan adenokarsinoma kolorektal tipe tidak spesifik yang memiliki ekspresi EGFR positif memiliki risiko 10 kali lebih besar ditemukan dengan P-stage P1 dibandingkan dengan kasus ekspresi EGFR negatif (IK 95% 1,177-86,846).Kata kunci: Adenokarsinoma kolorektal, Ekspresi EGFR, P-Stage, Faktor Prognostik
