"Latar Belakang: Adenokarsinoma duktal pankreas dan adenokarsinoma ampula vateri, tanpa melihat gambaran episentrum tumor, sulit dibedakan secara histopatologi. Gejala klinis tidak spesifik sehingga kasus yang ditemukan seringkali tidak memenuhi kriteria resectable. Gambaran radiologi juga tidak spesifik, padahal terapi dan prognosis keduanya berbeda. Adenokarsinoma duktal pankreas memiliki angka kesintasan rendah dibanding adenokarsinoma ampula vateri. Penentuan asal tumor, berasal dari duktal pankreas atau ampula vateri, sangat penting. SMAD4 diduga dapat menjadi salah satu panel diagnostik imunohistokimia. Penelitian ini dilakukan dengan melihat perbandingan ekspresi SMAD4 di adenokarsinoma ampula vateri dan adenokarsinoma duktal pankreas.Tujuan: Mengetahui perbandingan ekspresi SMAD4 pada adenokarsinoma duktal pankreas dan adenokarsinoma ampula vateri.Metode: Penelitian analitik observasional, desain potong lintang pada sediaan reseksi adenokarsinoma duktal pankreas dan adenokarsinoma ampula vateri, periode Januari 2013 hingga September 2021. Pengambilan sampel dilakukan secara total sampling. Adenokasinoma ampula vateri dengan subtipe pankreatobiliar dieksklusi. Pemeriksaan imunohistokimia menggunakan antibodi primer SMAD4. Data imunohistokimia dianalisis untuk melihat adakah perbedaan ekspresi SMAD4 pada adenokarsinoma di ampula vateri dan adenokarsinoma duktal pankreas.Hasil: Loss of SMAD4 didapatkan pada 12 kasus (60 %) adenokarsinoma duktal pankreas dan 8 kasus (44,4 %) adenokarsinoma ampula vateri. Tidak didapatkan hubungan loss of SMAD4 pada adenokarsinoma duktal pankreas dan adenokarsinoma ampula vateri (p=0,338).Kesimpulan: Tidak terdapat hubungan bermakna loss of SMAD4 pada adenokarsinoma duktal pankreas dan adenokarsinoma ampula vateri. Namun terdapat trend loss of SMAD4 lebih tinggi pada adenokarsinoma duktal pankreas dibanding adenokarsinoma ampula vateri subtipe intestinal dan mixed type dominansi intestinal.

ackground: Differentiating pancreatic ductal adenocarcinoma and ampullary adenocarcinoma without knowing the epicenter of the tumor is difficult. The clinical symptoms are non-specific. The cases found usually do not meet the operable criteria. Radiological examination is also non-specific, although the treatment and prognosis are different. Pancreatic ductal adenocarcinoma has lower survival rate than ampullary adenocarcinoma. It is very important to determine the origin of the tumor from pancreatic ductal or ampulla of Vater. SMAD4 is expected to be one of immunohistochemical diagnostic panel for the pancreatic ductal adenocarcinoma. This study compares the SMAD4 expression in pancreatic ductal adenocarcinoma and ampullary adenocarcinoma.

Objective: Knowing the comparison of SMAD4 expression in pancreatic ductal adenocarcinoma and ampullary adenocarcinoma.

Methods: Observational analytical study with cross sectional design, total sampling was performed on the resection specimens of pancreatic ductal adenocarcinoma and ampullary adenocarcinoma, period January 2013 to December 2021. Ampullary adenocarcinoma with pancreatobilliary subtype was excluded. Immunohistochemical examination using SMAD4 primary antibody. Immunohistochemical data will be analyzed to see SMAD4 expression difference between pancreatic ductal adenocarcinoma and ampullary adenocarcinoma.

Results: Loss of SMAD4 was found in 12 cases (66,7 %) of pancreatic ductal adenocarcinoma and 6 cases (44,4 %) of ampullary adenocarcinoma. There was no significant relationship between loss of SMAD4 in pancreatic ductal adenocarcinoma and ampullary adenocarcinoma (p=0,338).

Conclusions: There was no significant relationship between loss of SMAD4 in pancreatic ductal adenocarcinoma and adenocarcinoma of the ampulla of vater. However, there was a trend of higher SMAD4 loss in pancreatic ductal adenocarcinoma than ampullary vater adenocarcinoma of intestinal subtype and mixed type with intestinal dominance."

"[Pendahuluan: Proses karsinogenesis adenokarsinoma prostat terjadi akibat disregulasi kadar zinc dalam sel. Molekul zinc intrasel berperan dalam metabolisme aerob mitokondria dan induksi apoptosis. Penyerapan zinc diatur oleh protein ZIP1, berperan meningkatkan kandungan zinc sitoplasmik intrasel dengan membawa zinc dari cairan ekstrasel. Kadar zinc yang tinggi dan ekspresi protein ZIP1 banyak ditemukan pada epitel prostat normal, sedangkan pada kanker prostat ditemukan sedikit atau tidak ada ekspresi protein ZIP1. Penurunan ekspresi ZIP1 diduga dapat menghambat apoptosis, serta memacu perkembangan adenokarsinoma prostat. Penelitian ini bertujuan menganalisis korelasi ekspresi protein ZIP1 dan Caspase- 3 pada jaringan adenokarsinoma prostat berdasarkan Gleason score yang berbeda. Metode: Desain studi analitik retrospektif dengan desain potong lintang. Sampel penelitian ini adalah 31 sediaan blok parafin adenokarsinoma prostat yang memenuhi kriteria inklusi. Sediaan dipulas menggunakan teknik imunohistokimia untuk mengetahui ekspresi protein ZIP1 dan caspase-3. Ekspresi protein pada pulasan slide dihitung menggunakan program imageJ. Gleason score sebagai data sekunder yang didapatkan dari laporan kasus. Korelasi ekspresi kedua protein berdasarkan Gleason score dianalisis dengan uji korelasi Pearson menggunakan SPSS 11.5. Hasil: Rerata positivitas ekspresi ZIP1 pada adenokarsinoma prostate adalah 35% dan rerata positivitas caspase-3 adalah 33%. Terdapat korelasi positif bermakna antara ekspresi ZIP1 dan caspase-3 (r = 0.379 , p = 0,018). Terdapat korelasi positif antara ekspresi ZIP1 dan caspase-3 pada kelompok intermediate grade (r = 0.73, p = 0.01) dan korelasi lemah tidak bermakna pada kelompok high grade (r = 0.04, p = 0.48). Kesimpulan: Terdapat korelasi positif antara ekspresi ZIP1 dan ekspresi caspase- 3 pada adenokarsinoma prostat.

, Introduction: Carcinogenesis of adenocarcinoma of the prostate occurs due to dysregulation of zinc level within the cells. Intracellular zinc molecules contributes to mitochondrial aerobic metabolism. Its influx is regulated by a transporter protein ZIP1, whose non-presence is predicted to inhibit apoptosis, thus leads to the development of prostate adenocarcinoma. This study was aimed to analyze the correlation of ZIP1 and Caspase-3 expression in prostate adenocarcinoma with respect to its grading as represented by Gleason Score. Methods: This was a cross-sectional, retrospective analytical study on 31 formalyn-fixed, paraffin-embedded tissue that meet inclusion criteria. The specimen was stained using immunohistochemical technique for ZIP1 and Caspase-3. Protein expression of each case were counted using ImageJ analysis. Gleason score were acquired as secondary data from the cases’ reports. The correlation of their expression with respect of Gleason score were analyzed with Pearson’s correlation using SPSS 11.5.

Results: Mean expression level of ZIP1 and Caspase-3 in prostate adenocarcinoma were 35% and 33%, respectively. There was a significantly positive correlation between ZIP1 and Caspase-3 expression (r=0.379; p=0.018). However, their correlation was stronger in intermediate-grade group (r=0.73; p=0.01) and the correlation was much weaker in high-grade group (r=0.04; p=0.48).

Conclusion: There was a positive correlation between ZIP1 and caspase-3 expression in adenocarcinoma prostate.]"

"[ABSTRAKPendahuluan: Penurunan kadar Zink (Zn) pada prostat berkorelasi dengan peningkatan skor Gleason adenokarsinoma prostat dan menyebabkan rendahnya Caspase-3 sebagai eksekutor apoptosis. Tingkat ekspresi transporter Zn pada sel tumor prostat berhubungan dengan tingkat keganasannya. ZnT-1 merupakan transporter Zn ke luar sel prostat, sedangkan ZIP-1 merupakan transporter Zn ke dalam sel prostat. Ekspresi ZIP-1 turun pada adenokarsinoma prostat. Korelasi ZnT-1, ZIP-1 dan Caspase-3 diduga berpengaruh dalam karsinogenesis prostat, sehingga berpotensi untuk menjadi faktor prognosis adenokarsinoma prostat. Tujuan: Mempelajari korelasi ekspresi ZnT-1 dan aktivasi Caspase-3 terhadap skor Gleason, menganalisis korelasi ekspresi ZIP-1, ZnT-1 dan aktivasi Caspase- 3, serta mengetahui profil ekspresi ZnT-1 pada jaringan adenokarsinoma prostat yang berbeda skor Gleason, dibandingkan dengan jaringan Benign Prostatic Hyperplasia (BPH),Desain: Studi retrospektif analitik potong lintang. Metode: Sampel penelitian ini adalah 31 blok parafin prostat yang dikelompokkan menjadi BPH, adenokarsinoma prostat skor Gleason ≤ 7 dan skor Gleason > 7. Ekspresi ZnT-1 dinilai dengan pulasan imunohistokimia. Data ekspresi ZIP-1 dan Caspase-3 merupakan data sekunder dari penelitian Septiawan et al. Hasil: Ekspresi ZnT-1 berkorelasi dengan skor Gleason adenokarsinoma prostat. Ekspresi ZIP-1 berkorelasi dengan aktivasi Caspase-3 pada adenokarsinoma prostat dan adenokarsinoma prostat skor Gleason ≤ 7. Ekspresi ZnT-1 berkorelasi dengan ekspresi ZIP-1 pada adenokarsinoma prostat skor Gleason > 7. Ekspresi ZIP-1 berkorelasi kuat dengan aktivasi Caspase-3 pada adenokarsinoma prostat skor Gleason 8. Ekspresi ZnT-1 pada adenokarsinoma prostat skor Gleason > 7 lebih rendah dibandingkan pada skor Gleason ≤ 7, tetapi tidak dapat dianalisis kemaknaan perbedaannya dengan BPH karena hanya diperoleh 1 sampel BPH pada penelitian ini. Kesimpulan: Transporter Zn berpotensi untuk menjadi faktor prognosis adenokarsinoma prostat.

ABSTRACT"Background Previous studies suggested that Androgen Receptor AR expression could be used to evaluate the successful rate among patient with Benign prostate hyperplasia BPH or Adenocarcinoma acinar of the prostate CaP treated with hormonal therapy. AR plays role in prostate growth and differentiation, and maintains the normal state of the tissue. While in pathologic state, AR expression correlate with tumor grade and differentiation, and Gleason score GS . This study aimed to compare the expression of AR between BPH with CaP.Method This research use a cross sectional study conducted twenty cases of BPH and twenty five cases of CaP. Each tissue were stained using antibody against AR, and histologically reviewed. The captured photomicrographs were further analyze using histoscore H score .Result There was statistically signifinat levels PSA between BPH and CaP p 0,004 . The nucleus of stromal AR expression in BPH group compare to CaP group was statistically significant difference diagnose vs nucleus of stromal AR expression p 0,000 . Meanwhile, no significant difference is found between nucleus of epithelial AR expression between two group p 0,152 . The intensity expression AR in CaP with low Gleason score GS le 7 is higher than CaP with high Gleason score GS 7 Conclusion BPH expresess more nucleus of stromal AR than CaP. The higher Gleason score tends followed by declining intensity expression of AR. Thus suggest AR rsquo s role can use in prognosis, prediction and evaluation of hormonal theraphy of BPH or prostate malignancy."

"Di Indonesia angka kematian karena kanker terus meningkat dari 1,4% tahun 1972 menjadi 4,4% tahun 1992. Dari studi orospektif dan retrospektif diketahui bahwa karotenoid mengurangi risiko mendapatkan kanker payudara. Beta-karoten adalah salah satu karotenoid yang dikandung oleh minyak kelapa sawit (600.000 ug/Kg). Karena cara pengobatan kanker payudara yang berlaku selama ini (dengan pembedahan, radioterapi dan kemoterapi) cukup mahal, dan acapkali tidak terjangkau oleh sebagian golongan masyarakat, maka perlu dicari cara lain, di antaranya memanfaatkan beta-karoten yang ada dalam minyak kelapa sawit, namun perlu diteliti dosis ekstrak minyak kelapa sawit yang tepat. Penelitian ini dilakukan untuk mengetahui pengaruh pemberian ekstrak minyak kelapa sawit yang mengandung beta-karoten sebanyak 0,02 ug/ml, 0,1 ug/ml dan 0,5 ug/m1 terhadap pertumbuhan in vitro sel tumor kelenjar susu mencit C3H, menggunakan 5 kelompok masing-masing 7 ulangan dan terdiri atas 3 kelompok perlakuan dan 2 kelompok kontrol. Dengan melakukan analisis Ovarian diketahui tidak ada perbedaan yang bermakna antara kelompok kontrol dan perlakuan dosis 0,02 ug/ml. Kemaknaan terjadi pada dosis 0,1 ug/ml dan 0,5 pug/ml. Ditemukan bahwa makin besar dosis yang diberikan makin kecil rasio pertumbuhan biakan sel tumor. Selain itu dari hasil analisa varian indek label BUdR diketahui bahwa pemberian EMKS memperkecil nilai indek labelnya sesuai dengan dosis yang diberikan. Dengan demikian terlihat adanya pengaruh betakaroten dalam ekstrak minyak kelapa sawit terhadap pertumbuhan biakan in vitro sel tumor kelenjar susu mencit C3H, dalam wujud menurunnya rasio pertumbuhan dan indek label BUdR yang berarti dihambat sel yang memasuki fase s, sehingga laju pertumbuhan sel dihambat."

Introduction: Epidermal Growth Factor Receptor (EGFR) mutation is associated with Lung Adebocarcinoma carcinogenesis particularly in young patients which don?t have long exposure to smoke as carcinogen. This study investigate Profile of Epidermal Growth Factor Receptor Mutation and Survival in Young Patients with lung Adenocarcinoma.

Method: Retrospective and prospective observational cohort study in lung Adenocarcinoma <45 years old compare with olders. Data are taken from medical record Persahabatan hospital Jakarta 2012-2013 and we observed for progressivity and mortality in 2 years since diagnosis.

Results: A total 218 lung Adenocarcinoma consists of 65 young patients and 153 olders. Young lung Adenocarcinomas are female (58,3%), nonsmokers (66,7%), advanced stage (98,5%), performance status WHO ≤2, extrathoracic metastatics (43,1%). EGFR mutation in youngers are higher than olders (70,8%vs51%; p=0,007). Mutation in young patients consists are 36,9% exon 19 deletion; 30,8% exon 21 L858R mutation; 3,1% exon 21 L861Q mutation and 29,2% wild type. Overall survival (OS) young patients with EGFR mutation positive treated with EGFR tyrosine kinase inhibitor are 652 days (95% CI, 590-713 days), 1 year survival is 87,5% and progression free survival (PFS) are 345 days (95% CI, 323-366 days). Exon 19 deletion give higher PFS than exon 21 (RR 2,361; IK 95% 1,126-4,952; p=0,023). Overall survival young patients with EGFR wild type treated with conventional chemotherapy are 515 days (487-542 days, 95%), 1 year survival is 70,7% and their PFS are 202 days (137-266 days, 95% CI).

Conclusion: EGFR mutation profile in young lung Adenocarcinoma is important to choose first line therapy so that can increase their survival."
