Abstract

Background: Vascular Endothelial Growth Factor (VEGF) is an angiogenic factor that plays an important role in tumor angiogenesis. VEGF in meningioma is up-regulated and indicates its role as a proangiogenic factor. It has an association with tumor recurrence and progression. This study aims to determine the differences in VEGF expression in low-risk and high-risk meningiomas at Sanglah General Hospital, Bali, Indonesia.Methods: This study was a cross-sectional analytical study with a sample size of 52, which came from meningioma patients examined histopathologically at the Anatomical Pathology Laboratory of Sanglah General Hospital from January to December 2019. The VEGF immunohistochemical staining was performed and interpreted using Histo score (H-score). VEGF expression was categorized into high and low expression, with the cut-off value determined based on the median value. Data were analyzed using SPSS version 20 for Windows.Methods: The results showed that out of 52 meningioma samples, 37 (71.1%) cases of low-risk meningiomas with low VEGF expression, 6 cases (11.5%) of low-risk meningiomas with high VEGF expression, and 9 cases (17.3%) of high-risk meningiomas with high VEGF expression. There was no high-risk meningioma with low VEGF expression. There was a significant difference in VEGF expression between the low-risk and high-risk meningioma groups (p = 0.00), and high VEGF expression had a prevalence risk for the incidence of high-risk meningioma by 2.5 times (95% CI=1.3-4.6).Conclusion: Based on the results of this study, it was concluded that there was a VEGF expression difference between low-risk and high-risk meningiomas in Sanglah General Hospital Denpasar and high VEGF had a prevalence risk for the occurrence of high-risk meningiomas by 2.5 times. Latar Belakang: Vascular Endothelial Growth Factor (VEGF) merupakan faktor angiogenik yang berperan penting dalam angiogenesis tumor.

Abstract

Background: Lymph Node Metastasis (LNM) is considered the most important prognostic factor in breast cancer. The progress of lymphatic metastasis is thought to involve the proliferation of lymphatic vessels (lymphangiogenesis), Lymph Vessel Invasion (LVI), and lymph node metastasis step by step. This study aims to evaluate the association between LVD with LVI and regional LNM in invasive breast carcinoma of no special type.Methods: This study used a cross-sectional analytical study, using a sample of 38 paraffin-embedded tissue from the patient with invasive breast carcinoma of no special type in Sanglah General Hospital, Bali, Indonesia, in 2018. The sample will be used to assess LVD and LVI by D2-40 immunohistochemistry. Expression of D2-40 with vigorous-intensity was evaluated on the membrane and cytoplasm of lymphatic endothelial cells to determine the definition of lymphatic vessels. Lymph vessel density was determined by counting the number of lumens of peritumoral lymphatic vessels in five fields of view with the densest lymphatic vessel lumen using a Leica microscope (DM750, 400x, area 0.225mm2). Data were analyzed using SPSS version 24 for Windows.Results: The LVD cut-off value is 16.5 lymphatic vessel lumens/0.225 mm2 (65.4% for sensitivity and area Under the Curve (AUC)=70.2%). Then cases were classified into the category of high LVD (?16,5 lymphatic vessel lumen/0,225 mm2) and low LVD (<16.5 lymphatic vessels lumen/0,225 mm2). The study found a statistically significant association between LVD and lymph vessel invasion (PR=3.6; p=0.043; 95%CI=0.88-14.78) and regional lymph node metastases (PR =1.7; p=0.02; 95%CI=1.03-2.79).Conclusion: This study proved an association between LVD with lymph vessel invasion and regional lymph node metastases.  Latar Belakang: Metastasis Kelenjar Getah Bening (KGB) dianggap sebagai faktor prognostik yang paling penting pada kanker payudara. Perkembangan metastasis limfatik diduga melibatkan proliferasi pembuluh limfatik (limfangiogenesis), Lymph Vessel Invasion (LVI) atau invasi limfatik, dan metastasis kelenjar getah bening secara bertahap. Penelitian ini bertujuan untuk mengevaluasi hubungan antara Lymph Vessel Density (LVD) dengan invasi limfatik dan metastasis kelenjar getah bening regional pada karsinoma payudara invasif tipe tidak spesifik.Metode: Penelitian ini menggunakan metode analitik potong lintang dengan sampel 38 blok parafin dari pasien karsinoma payudara invasif tipe tidak spesifik di RSUP Sanglah, Bali, Indonesia tahun 2018. Penilaian LVD dan LVI dengan pulasan imunohistokimia D2-40. Ekspresi D2-40 dengan intensitas yang kuat dievaluasi pada membran dan sitoplasma sel endotel limfatik untuk menetapkan definisi pembuluh limfatik. Lymph vessel density ditentukan dengan menghitung jumlah lumen pembuluh limfatik peritumoral pada lima lapangan pandang yang memiliki lumen pembuluh limfatik terpadat, menggunakan mikroskop Leica (DM750, 400x, luas area 0,225mm2). Data dianalisis dengan SPSS versi 24 untuk Windows.Hasil: Nilai cut-off LVD adalah 16,5 lumen pembuluh limfatik/0,225 mm2 (sensitivitas 65,4% dan Area Under the Curve (AUC)=70,2%). Kemudian kasus dikategorikan menjadi LVD tinggi (?16,5 lumen pembuluh limfatik / 0,225 mm2) dan LVD rendah (<16,5 lumen pembuluh limfatik / 0,225 mm2). Hasil analisis statistik menunjukkan bahwa terdapat hubungan antara LVD dengan invasi limfatik (PR=3,6; p=0,043; IK 95%=0,88-14,78) dan metastasis KGB regional (PR=1,7; p=0,02; IK 95%=1,03-2,79).Kesimpulan: Penelitian ini membuktikan bahwa terdapat hubungan antara LVD dengan invasi limfatik dan metastasis KGB regional.

Abstract

Background: Colorectal carcinoma is a malignant epithelial tumor of the large bowel that occurs due to extrinsic and intrinsic factors. BRAF V600E gene mutation was found in about 10-15% of colorectal carcinoma. This mutation was associated with aggressive biologic behaviors, metastasis and lesser responsiveness to EGFR inhibitors therapy. This study aims to determine the association between BRAF V600E expression with metastasis and the degree of differentiation of colorectal adenocarcinoma.Methods: This cross sectional study involved 43 samples of adenocarcinoma colorectal patients who had histopathological examinations in the period 2018-2019. Immunohistochemical were performed to assess the expression of BRAF V600E. This expression was concluded positively if 75% or more tumor cells showed intense cytoplasmic staining. Data were analyzed using SPSS version 20 for Windows.Results: Within 43 colorectal adenocarcinoma cases, it was found 7 cases (16.3%) had a positive expression of BRAF V600E. This expression was found in metastasis cases (7/25), not found in cases without metastasis (0/18). There was an association between BRAF V600E expression and metastasis (p=0.014). The positive expressions of BRAF V600E were only found in low-grade differentiation (7/35 cases), were not found in high-grade differentiation (0/8 cases), and no association between BRAF V600E mutation and the degree of differentiation (p=0.167).Conclusion: There was an association between BRAF V600E expression and metastasis of colorectal adenocarcinoma. There was no significant association between BRAF V600E expression and the degree of differentiation of colorectal adenocarcinoma. Latar Belakang: Karsinoma kolorektal merupakan suatu tumor ganas epitelial usus besar yang terjadi akibat pengaruh dari faktor ekstrinsik dan intrinsik. Mutasi gen BRAF V600E ditemukan pada sekitar 10-15% kasus karsinoma kolorektal. Mutasi ini berkaitan dengan perilaku biologik agresif, metastasis, serta kurangnya respon terhadap terapi dengan inhibitor EGFR. Penelitian ini bertujuan untuk mengetahui adanya hubungan antara ekspresi BRAF V600E dengan metastasis dan derajat diferensiasi adenokarsinoma kolorektal.Metode: Penelitian menggunakan rancangan analitik potong lintang dengan 43 sampel penderita adenokarsinoma kolorektal yang telah dilakukan pemeriksaan histopatologi pada periode tahun 2018-2019. Pulasan imunohistokimia dikerjakan untuk menilai ekspresi BRAF V600E. Ekspresi BRAF V600E dinyatakan positif jika 75% atau lebih sel tumor mununjukkan pulasan sitoplasma dengan intensitas kuat. Data dianalisis dengan SPSS versi 20 untuk Windows.Hasil: Dari 43 kasus, ditemukan 7 kasus (16,3%) dengan ekspresi BRAF V600E positif. Ekspresi ini hanya dijumpai pada kasus dengan metastasis (7 dari 25 kasus), tidak dijumpai pada kasus tanpa metastasis (0 dari 18 kasus). Didapatkan hubungan bermakna antara ekspresi BRAF V600E dengan metastasis (p=0,014). Ekspresi BRAF V600E positif hanya ditemukan pada kasus derajat diferensiasi rendah (7 dari 35 kasus), tidak ditemukan pada derajat tinggi (0 dari 8 kasus), dan hubungan tersebut tidak bermakna secara statistik (p=0,167).Kesimpulan: Terdapat hubungan antara ekspresi BRAF V600E dengan metastasis pada adenokarsinoma kolorektal. Tidak terdapat hubungan antara ekspresi BRAF V600E dengan derajat diferensiasi pada adenokarsinoma kolorektal.

Abstract

Background: Triple Negative Breast Cancer (TNBC) is a heterogeneous group of breast cancer. Some cases show a good outcome; others show higher recurrence and metastasis. There are several molecular subtypes of TNBC. Basal-like 2 (BL-2) subtype involves Epidermal Growth Factor (EGF) signaling pathway, enriched with many growth factor receptors such as EGFR. This study aims to determine the association between EGFR expression and various clinicopathological parameters in TNBC patients in Sanglah Hospital Denpasar.Methods: This study was an analytical cross-sectional study involving 35 patients TNBC who were examined histopathologically at the Anatomical Pathology Laboratory in Sanglah Hospital Denpasar from January 1st 2016 to December 31st 2020. Re-evaluation of the specimen was conducted to assess histopathological diagnosis, grade, tumor size (T), Lymphovascular Invasion (LVI) and nodal status (N). EGFR expression was evaluated by immunohistochemistry staining and then interpreted based on the intensity and continuity of the stained cell membrane. The association between EGFR expression and clinicopathological parameters was analyzed with a Chi-Square test with a 0.05 significance level.Result: The result of this study showed the age range of TNBC patients was 29-70 years with mean age was 49.7±11.4 years. There were significant association between EGFR expression with T (p=0.008; PR = 2.7; 95%CI 1.4-5.1), LVI (p=0.018; PR = 3.0; CI95% 1.300-7.137) and N (p=0.033; PR=2.7; CI95% 1.121-6.543). There were no significant association between EGFR expression with age (p=1.000), grade (p=0.689) and Ki67 index (0.689).Conclusion: It can be concluded that there are associations between EGFR expression with T, LVI and N. There was no association between EGFR expression with age, grade and Ki67 index.  Latar Belakang: Triple negative breast cancer (TNBC) merupakan kelompok kanker payudara yang heterogen. Sebagian kasus menunjukkan survival yang baik, namun sebagian lainnya dengan rekurensi dan metastasis yang lebih tinggi. Terdapat beberapa subtipe molekuler dari TNBC, salah satunya subtipe Basal-like 2 (BL2) yang melibatkan jalur pensignalan Epidermal Growth Factor (EGF), melalui berbagai reseptor factor pertumbuhan, salah satunya EGFR. Penelitian ini bertujuan untuk mengetahui hubungan antara ekspresi EGFR dengan berbagai parameter klinikopatologi pada kasus TNBC di RSUP Sanglah Denpasar.Metode: Penelitian ini merupakan studi analitik potong lintang dengan besar sampel 35 kasus TNBC yang diperiksa histopatologi di Laboratorium Patologi Anatomi RSUP Sanglah Denpasar dari 1 Januari 2016 hingga 31 Desember 2020.

Abstract

Gastric abnormalities show nonspecific gastrointestinal symptoms and similarly radiological findings. Intra and extra luminal gastric wall thickening are the most common finding in benign and malignant pathologic process. This aim of this case report was to describe several characteristics such as the location and size of the lesion, involvement of the gastric wall and surrounding structures, calcifications, and contrast enhancement pattern which can assist in radiological diagnosis. Several cases at our institution have similar gastrointestinal complaints, however, there were different lesions characteristic found in contrast enhanced abdominal CT scan. The first case 72-years-old man experienced hematemesis with radiologic finding diffuse gastric mucosal thickening as well as homogenous contrast enhancement but without calcification.  The second case 37-years-old man complaint dizziness and melena with radiologic finding large tumor more than 10 cm in size, amorph calcification and heterogenous contrast enhancement. The last 60-years-old man case experienced melena and hematemesis, from abdominal CT scan showed irregular gastric mucosal thickening with heterogenous contrast enhancement and fat stranding around the lesion, without calcification. Methods used in these cases were contrast-enhanced abdominal CT scan, esophagogastroduodenoscopy (EGD), and biopsy in order to determine the diagnosis. Contrast-enhanced abdominal CT scan plays a vital role in describing the lesion characteristics which affects the determination of treatment options and future prognosis.
