Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer with aggressive behavior. Tumor stage and grade are important parameter in diagnosis. Data about the clinical and pathology profile of ccRCC in Indonesia is limited, therefore further information is needed. The study aimed to determine clinicopathologic profile of ccRCC in Soetomo Academic General Hospital (SAGH). This descriptive study was conducted retrospectively with cross-sectional approach. Clinical and histopathological archives of ccRCC specimen were retrieved during January 2016 to December 2020. The total number of ccRCC cases obtained was 38 cases, the most cases (11) occurred in 2016. The average of patient’s age was 55.64 years. Patients were predominantly male (71.1%), with a ratio to female 2.5:1. The tumors mostly filled the entire kidney, in 15 (39.5%) cases. Most pT stage distribution was pT2, in 15 (39.5%) cases. Most N stage distribution was N0, in 23 (60.5%) cases. Only 5 (13.2%) cases showed multiple pulmonary nodules which suspected to be metastatic (M1). The most common tumors grade was G4, in 17 (44.7%) cases. In conclusion, ccRCC patient were predominantly male, tumors mostly high grade, filled entire kidney, not penetrated renal capsule, and not metastasize to regional lymph nodes.

Diabetes mellitus (DM) is one of the major causes of death in the world. There are two types of DM—type 1 DM and type 2 DM. Type 1 DM can only be treated by insulin injection whereas type 2 DM is commonly treated using anti-hyperglycemic agents. Despite its effectiveness in controlling blood glucose level, this therapeutic approach is not able to reduce the decline in the number of functional pancreatic β cells. MST1 is a strong pro-apoptotic kinase that is expressed in pancreatic β cells. It induces β cell death and impairs insulin secretion. Recently, a potent and specific inhibitor for MST1, called XMU-MP-1, was identified and characterized. We hypothesized that treatment with XMU-MP-1 would produce beneficial effects by improving the survival and function of the pancreatic β cells. We used INS-1 cells and STZ-induced diabetic mice as in vitro and in vivo models to test the effect of XMU-MP-1 treatment. We found that XMU-MP-1 inhibited MST1/2 activity in INS-1 cells. Moreover, treatment with XMU-MP-1 produced a beneficial effect in improving glucose tolerance in the STZ-induced diabetic mouse model. Histological analysis indicated that XMU-MP-1 increased the number of pancreatic β cells and enhanced Langerhans islet area in the severe diabetic mice. Overall, this study showed that MST1 could become a promising therapeutic target for diabetes mellitus.

Approximately 20-30% of all cervical cancer cases are adenocarcinoma and adenosquamous carcinoma. Around 70% of all of these types of cancer are related to infection of Human Papillomavirus (HPV). This study evaluated the distribution of HPV genotype in cervical adenocarcinoma and adenosquamous carcinoma. A cross-sectional study was conducted at the Department of Anatomic Pathology, Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, from January to December 2015. The sample were 22 formalin-fixed paraffin-embedded (FFPE) of cervical adenocarcinoma tissues and adenosquamous carcinoma tissues. FFPE was used for DNA extraction and followed with HPV genotyping to detect 40 genotypes of HPV, including low risk (LR) and high risk (HR) HPV. The histopathological types of adenocarcinomas were adenocarcinoma NOS and mucinous adenocarcinoma, while the adenosquamous carcinoma types were adenosquamous carcinoma and adenosquamous carcinoma glassy. All of the specimens were infected by HPV. In cervical adenocarcinoma, the infection was by HPV 6, 11, 16, 18, 31, 45, 68B, and 72, and in adenosquamous carcinoma by HPV 6, 16, 18, 45, and 59. HPV 18 was predominant, which was found in 13/22 (59.1%) in adenocarcinoma and 19/22 (86.4%) in adenosquamous carcinoma. Single infection and multiple infections in adenocarcinoma were 13/22 (59.1%) and 9/22 (40.9%), while in adenosquamous carcinoma were 21/22 (95.5%) and 1/22 (4.5%) respectively. The most common HR HPVs found in this study were HPV 18, HPV 45, HPV 16 and LR HPV are HPV 11, HPV 6.

Colorectal adenocarcinoma is positioned as the third of most common cancer which the cases rise in Indonesia lately. More than 90% of colorectal carcinoma are adenocarcinoma type. One of prognostic factor of colorectal adenocarcinoma is invasion state of the tumor (T). Uncontrollable proliferation of tumor cell causes transformation of paracellular permeability that increase claudin-4 expression (a protein located on main integral membrane). Claudin-4 activation influence the expression and activity of MMP-2 directly or by altering transduction signal. Expression of claudin-4 and MMP-2 play a role in tumor invasion. Analyzing correlation of claudin-4 and MMP-2 toward invasion state of the tumor (T stadium) on colorectal adenocarcinoma. Analytical observation was conducted on 47 samples of colorectal adenocarcinoma with different invasion state collected by Laboratory of Pathological Anatomy, Dr. Soetomo General Academic Hospital during 2015-2018. Immunohistochemistry was conducted using both claudin-4 and MMP-2 antibodies. Expression of claudin-4 and MMP-2 were semiquantitatively measured then statistically analyzed. Significant result could be obtained in comparison between claudin-4 and tumor invasion state (p=0.773). The significant result could be obtained in comparison between MMP-2 and tumor invasion state (p=0.920). It also could be observed in comparison between claudin-4 and MMP-2 (p=0.638). In summary, claudin-4 and MMP-2 play a role on tumor invasion colorectal adenocarcinoma. It was showed by significant result between claudin-4 and MMP-2 expressions compared to invasion state of colorectal adenocarcinoma.

Tujuan: Penelitian ini bertujuan untuk mengetahui prevalensi lesi prekanker serviks dengan cara melakukan skrining kanker serviks menggunakan pemeriksaan Pap smear.Bahan dan Metode: Penelitian ini merupakan penelitian observasional deskriptif dengan metode pendekatan cross sectional yang dilakukan pada 140 wanita, terdiri dari 90 orang dari Puskes-mas Tanah Kali Kedinding Surabaya, dan 50 orang dari Rumah Sakit Mawadah Mojokerto, dengan usia 20-70 tahun. Pemeriksaan spesimen sitologi serviks dengan pengecatan Papaniculaou dan klasifikasi hasil pemeriksaaan sitologi berdasar-kan klasifikasi Papaniculaou dan sistim Bethesda. Pemeriksaan inspeksi visual asam asetat (IVA) adalah metode lain untuk skrining kanker serviks dilakukan dengan mengoleskan asam asetat 5% pada area serviks dan melakukan pengamatan satu menit kemudian.Hasil: Hasil pemeriksaaan Pap smear menunjukkan Papaniculaou kelas I (sama dengan normal pada klasifikasi sistim Bethesda) yaitu 12.1%, kelas II (sama dengan NILM pada klasifikasi sistim Bethesda) yaitu 86, 4%, dan kelas III (sama dengan LSIL pada klasifikasi sistim Bethesda) yaitu 1,4%. Hasil pemeriksaan IVA menunjukkan 6,43% positif dan 93,57% negatif. Hasil pemeriksa-an IVA positif terdapat pada 9/140 orang yang merupakan proses keradangan dan infeksi, bukan merupakan lesi prekanker.Simpulan: Prevalensi lesi prekanker yaitu 1,4%. Pemeriksaan IVA menunjukkan hasil positif semu yang disebabkan oleh proses radang atau infeksi pada serviks.

The objective of this study is to analyze the expression of E6 Humanpapilloma virus (HPV), p53, and p16INK4A in cervical adenocarcinoma grade well differentiated (WD), moderately differentiated (MD), and poorly differentiated (PD). A cross sectional study conducted at Department of Anatomic Pathology, Dr. Soetomo General Academic Hospital Surabaya Indonesia using formalin fix paraffin embedded (FFPE) from cervical normal and cervical adenocarcioma grade WD, MD, and PD. The expression of E6 HPV, p53, and p16INK4A was performed by immunohistochemistry (IHC) staining. Data were analyzed with Kruskal-Wallis and continued with Mann-Withney test. The expression of E6 HPV in the cervical adenocarcinoma showed 35.9% specimens represented negative and 64.1% specimens represented positive. There was no significant difference in the expression of E6 HPV and p53 in cervical adenocarcinoma between grade WD, MD, and PD. The p16INK4A was overexpressed, shown as diffuse appearance in 89.7% of the specimens. There was a significant difference in the expression of p16INK4A between grade WD and MD with PD. In conclusion, some of cervical adecarcinoma were not caused by infection of HPV type 16 or 18 and the expression of p16INK4A might take a role in the developing of malignancy that caused by infection of HPV.
