"[Pendahuluan: Sejak tahun 70-an hingga sekarang, skor Gleason merupakan parameter penting pada penatalaksanaan kanker prostat. Biopsi prostat yang umum dipakai untuk membedakan antara kondisi jinak dan ganas semakin menjadikan skor Gleason berperan penting dalam menentukan tatalaksana selanjutnya. Meskipun demikian, terdapat diskrepansi antara skor Gleason yang diambil secara biopsi dan paskaoperasi.Tujuan: Untuk menentukan perbedaan skor Gleason sebelum dan setelah dilakukan prostatektomi radikal, dan untuk mencari faktor-faktor yang berperan dalam peningkatan skor Gleason.Metode: Dilakukan evaluasi laporan patologi dari spesimen prostat yang didapatkan secara biopsi dan paska prostatektomi radikal antara Januari 2004 sampai Desember 2013. Kriteria eksklusi dari studi ini adalah laporan-laporan yang tidak mencantumkan skor Gleason ataupun diagnosis selain adenokarsinoma prostat.Hasil: Studi ini menginklusikan 36 subjek dengan adenokarsinoma prostat yang telah menjalani prostatektomi radikal. Skor Gleason 6 merupakan skor tersering yang dilaporkan pada biopsi, sedangkan skor Gleason 7 merupakan skor tersering yang dilaporkan pada spesimen prostatektomi radikal. Diantara subjek, 58,3% (n=21) memiliki perbedaan antara skor Gleason biopsi dan prostatektomi radikal; 11,1% (n=4) memiliki penurunan dan 47,2% (n=17) mengalami peningkatan. Dengan menggunakan analisis statistik dijumpai bahwa rendahnya densitas PSA (PSAD) memiliki korelasi dengan likelihood peningkatan (r=0,658, p=0,006).Kesimpulan: Sebagian besar pasien memiliki perbedaan antara skor Gleason hasil biopsi dan paskaoperasi dimana terlihat kecenderungan peningkatan dibandingkan dengan penurunan skor. PSAD merupakan faktor yang berkorelasi dengan peningkatan skor Gleason., Introduction: Since its introduction in mid 70 until now, Gleason Score is an important parameter in the treatment of prostate cancer. The common practice of prostate biopsy to differentiate between malignant and benign condition of the prostate, hence makes Gleason score plays important role in determine the next step of treatment. Still there is a discrepancy between Gleason score taken from biopsy and postoperatively.Aim: To determine the Gleason score difference before and after radical prostatectomy, and to find factors that has a role in the upgrading of Gleason score.Methods: We evaluated pathology reports of prostate specimens obtained from biopsy and after radical prostatectomy between January 2004 until December 2013. Exclusion criteria of this study were reports that failed to mentioned Gleason score or a diagnosis apart from adenocarcinoma of the prostate.Results: This study enrolled 36 subjects with adenocarcinoma of the prostate who underwent radical prostatectomy. Gleason score 6 was the most reported score in initial biopsy while Gleason score 7 was the most reported in radical prostatectomy specimen. Among the subjects 58.3% (n=21) had diferrences of Gleason score between biopsy and radical proistatectomy; 11.1% (n=4) had a downgrading and 47.2% (n=17) had an upgrading. Using statistical analysis we found out that low prostate specific antigen densities (PSAD) had correlation with upgrading likelihood (r 0.658, p = 0.006)Conclusion: More than half of our patient had differences between biopsy Gleason score and postoperative scores with majority showed a likelihood of upgrading rather than downgrading, PSAD was the factors that correlates with upgrading in Gleason score.]"

"[ABSTRAKTujuan: Insiden kanker prostat secara global terus meningkat. Meskipun dapat dilakukan deteksi dini kanker prostat, perlu dipahami bahwa progresivitas penyakit ? menjadi metastasis ? berbeda untuk setiap pasien. Penelitian ini bertujuan untuk mengamati aspek-aspek yang mungkin berperan sebagai faktor prediktif metastasis pada kanker prostat tidak terpalpasi.Material dan Metode: Data dikumpulkan dari Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo dan Rumah Sakit Pusat Kanker Nasional Dharmais sejak tahun 1995-2013. Pasien dengan kanker prostat tidak terpalpasi kemudian dibagi menjadi dua kelompok: dengan metastasis dan tanpa metastasis. Usia, volume prostat, nilai prostate-spesific antigen (PSA), Gleason score sum group, stadium tumor, Karnofsky performance score (KPS), kadar hemoglobin, dan kadar kreatinin serum merupakan faktor yang dianalisis dalam penelitian ini. Data dianalisis menggunakan analisis bivariat dan uji regresi logistik. Hanya pasien dengan data lengkap yang dimasukkan dalam penelitian ini.Hasil: Didapatkan 91 pasien dengan data lengkap, 59 pasien (64,83%) tanpa metastasis dan 32 pasien (35,16%) dengan metastasis. Terdapat perbedaan statistik yang signifikan antara kelompok tanpa metastasis dan kelompok dengan metastasis, yakni untuk PSA (13.7ng / mL vs 71.5ng / mL; p = 0,001), kadar hemoglobin (13,60 g / dL vs 12,25 g / dL; p = 0,002), dan KPS (90 vs 90 ; p = 0,004). Perbedaan yang signifikan secara statistik juga didapatkan pada kelompok GSS (35 dan 24 pada kelompok tanpa metastasis vs 12 dan 20 pada kelompok dengan metastasis; p = 0,047). Usia, volume prostat, stadium tumor, dan kadar kreatinin antara kedua kelompok tidak memiliki perbedaan signifikan secara statistik (p> 0,05). Nilai pretreatment PSA adalah satu-satunya faktor prediktif untuk metastasis dengan odds ratio 1.014 (95% CI, 1,005-1,022; p = 0,002).Kesimpulan: Sebagian besar pasien kanker prostat tidak terpalpasi terdeteksi pertama kali tanpa metastasis. Nilai pretreatment PSA yang diperoleh pada kunjungan awal pasien dapat digunakan sebagai faktor prediktif metastasis di masa depan.

ABSTRACTObjective: Prostate cancer incident is globally increasing. Despite early detection of prostate cancer, the progressivity of the disease itself toward metastatic disease remains different for each patient. The purpose of this study is to observe aspects that may have roles as predictive factors for metastasis in nonpalpable prostate cancer.Materials and Methods: Data was collected from National Hospital Cipto Mangunkusumo and Dharmais National Cancer Center Hospital from 1995-2013. Patients with nonpalpable prostate cancer then divided into two groups: metastasis-free group and metastasis group. Age, prostate volume, pretreatment Prostate-specific antigen (PSA) value, Gleason score sum group, tumor stadium, Karnofsky performance score (KPS), hemoglobin level, and serum creatinine level were factors that were analyzed in the study. The data was analyzed using bivariate analysis and logistic regression test. Only patients with complete data are included in the study.Results: There are 91 patients with complete data, 59 patients (64.83%) were patients without metastasis and 32 patients (35.16%) were with metastasis. There was significant statistical difference between no metastasis group with metastasis group for PSA (13.7ng/mL vs71.5ng/mL; p = 0.001), hemoglobin level (13.60 g/dL vs 12.25 g/dL; p = 0.002), and KPS (90vs90; p = 0.004). There was also significant statistical difference in GSS groups (35 and 24 in metastasis-free group vs 12 and 20 in metastasis group; p = 0.047).

"Telah diketahui bahwa estrogen dan reseptor estrogen sangat berpengaruh pada sistem reproduksi, perkembangan payudara dan pembentukan kanker pada wanita. Namun efek estrogen pada sistem reproduksi pria serta mekanisme estrogen pada terjadinya kanker pada pria, khususnya kanker prosat masih belum jelas. Dari sekumpulan penelitian didapatkan kemungkinan estrogen dan reseptor estrogen berperan pada terjadinya kanker pada pria, terutama kanker prosat Reseptor estrogen dapat ditemukan pada stroma dan sel epitel prostat.

Prostate cancer is the second most frequently diagnosed cancer and the sixth leadingcause of cancer death in men worldwide. It was estimated 914.000 new cases werefound and responsible for 6% (258.400) of total cancer deaths in men in 2008.Indonesian Prostate Cancer Risk Calculator (IPCRC) was developed from a multicentricstudy to predict the risk of prostate cancer in suspected patient. An externalvalidation is needed to c onfirm the validity of the calculator. We included all benignprostatic hyperplasia (BPH) and prostate cancer (PCa) patients who underwent prostatebiopsy and prostatectomy in Adam Malik Hospital between August 11th and December31st 2014. The relationship between variables affecting the percentage of prostatecancer risk were evaluated, including: age, PSA level, prostate volume, and digitalrectal examination (DRE) findings. We calculated the risk of prostate cancer for eachpatient using IPCRC and analyse the results using the receiver operating characteristic(ROC) curve. We also compared them with the area under curve (AUC) of PSA results.There were 21 PCa and 24 BPH patients in our study. The mean ages, PSA, and prostatevolume were 66.8±7.3 years old; 27.3±32.2 ng/ml and 64.9±38.1 ml, repectively.Abnormal DRE was found in 6 PCa and 1 BPH.

Introduction: Prostate cancer is the most frequent form of cancer in males, being also second cause of death by cancer. Digital Rectal Examination (DRE) is the basic examination and early diagnosis for prostate cancer. The Prostate-Specific Antigen (PSA) assay is currently considered the most useful tumor marker for detecting prostate cancer. Both the American Cancer Society and American Urologic Association recommended annual cancer screening with both Digital Rectal Examination (DRE) and PSA.

Objective: The objective of this study is to understand the correlation between DRE and PSA level in prostate cancer at Sardjito General Hospital Yogyakarta during januari 2011 until december 2011.

Research Method: This is a case control study. The data were retrospectively collected from medical record in sardjito general hospital who had abnormal DRE or normal DRE with PSA ≥ 10 ng/dl during januari 2011 until December 2011. The DRE and PSA value were examined in the first time they came to the hospital. A chi-square was performed to analyzed the nominal data with SPSS 18.

Result: There are 87 patients were collected during januari 2011 until December 2011 who had abnormal DRE or normal DRE with PSA ≥ 10 ng/dl. The median age was 70 years, median PSA level was 10,9 ng/dl. Of these patient, we found abnormal DRE in 43 (49,4%), normal DRE in 44 (50,6%), PSA ≥ 10 ng/dl was 69 (79,3%) and PSA < 10 ng/dl was 18 (20,7%). Digital Rectal Examination and PSA was statistically significant to detected prostate cancer, 67,2% vs 32,8% (p < 0,001) and 71,9% vs 28,1% (p = 0,002), respectively. All patient who had abnormal DRE and PSA ≥ 10 ng/dl were diagnosed with prostate cancer (p < 0,001).

Conclusion: Digital Rectal Examination (DRE) and Prostate Specific Antigen (PSA) are the best predictor for prostate cancer. "

Jumlah kematian dapat dikurangi dengan deteksi dini menggunakan machine learning. Salah satunya adalah klasifikasi data kanker prostat. Data kanker yang digunakan memiliki berbagai fitur, tetapi tidak semua fitur adalah fitur penting. Dalam penelitian ini, kami menggunakan Support Vector Machine-Recursive Feature Elimination (SVM-RFE) dan One Dimensional Naïve Bayes Classifier (1-DBC) sebagai metode seleksi fitur. Dalam kedua metode itu akan mendapatkan peringkat untuk setiap fitur. Penggunaan kedua metode ini dalam klasifikasi data kanker prostat menghasilkan tingkat evaluasi yang tinggi. Kedua metode ini dapat menghasilkan tingkat akurasi 100%, precision 100%, dan recall 100% pada metode klasifikasi Random Forest. Dan menghasilkan tingkat akurasi 95%, precision 100%, dan recall 94,11% pada metode klasifikasi SVM. Dalam evaluasi tambahan, SVM-RFE memiliki running time lebih rendah dari 1-DBC.

Death caused by cancer is expected to continue to increase, especially for prostate cancer. This disease is the most common type of cancer for men in the world. The number of deaths can be reduced by early detection using machine learning. One of them is the classification of prostate cancer data. Cancer data used has various features, but not all features are essential features. In this study, we use Support Vector Machine-Recursive Feature Elimination (SVM-RFE) and One Dimensional Naïve Bayes Classifier (1-DBC) as a feature selection method. In both methods, it will get a rating for each feature. The use of these two methods in the classification of prostate cancer data produces a high level of evaluation. Both of these methods can produce 100% accuracy, 100% precision, and 100% recall in the Random Forest classification method. And it produces 95% accuracy, 100% precision, and 94.11% recall in the SVM classification method. In the additional evaluation, SVM-RFE has a running time lower than 1-DBC."

"Latar belakang: Clinically significant prostate cancer (csPCa) merupakan kanker prostat yang mempunyai kemungkinan progresi lokal, metastasis, rekurensi, dan kematian yang sedang hingga tinggi, serta tata laksana yang lebih agresif. Penelitian ini bertujuan untuk membantu diagnosis antara csPCa dan bukan csPCa menggunakan rasio apparent diffusion coefficient (rADC) lesi prostat dengan urine. Metode: Penelitian dilakukan pada lesi prostat kategori 3-5 prostate imaging-reporting and data system yang telah dibiopsi prostat transperineal tertarget magnetic resonance imaging (MRI) dengan ultrasound/MRI fusion software di Rumah Sakit Umum Pusat Nasional Dokter Cipto Mangunkusumo pada Juni 2019 hingga Maret 2021. rADC lesi prostat dengan urine merupakan perbandingan rerata nilai apparent diffusion coefficient (ADC) lesi prostat dan urine di vesica urinaria pada MRI prostat peta ADC potongan aksial multi-institusi. rADC lesi prostat dengan urine antara csPCa (adenokarsinoma asinar prostat dengan skor Gleason ≥7) dan bukan csPCa (jaringan prostat nonneoplastik atau adenokarsinoma asinar prostat dengan skor Gleason 6) dibandingkan dan ditentukan nilai titik potongnya menggunakan receiver operating curve. Hasil: Terdapat perbedaan rADC lesi prostat dengan urine yang bermakna antara 19 lesi prostat yang merupakan csPCa dan 35 lesi prostat yang bukan merupakan csPCa, dengan nilai tengah rADC lesi prostat dengan urine pada csPCa 0,21 (0,11-0,33), nilai tengah rADC lesi prostat dengan urine pada bukan csPCa 0,43 (0,30-0,61), dan nilai p <0,001. Nilai titik potong rADC lesi prostat dengan urine dalam membedakan csPCa dan bukan csPCa adalah 0,30 dengan sensitivitas 94,73% dan spesifisitas 100%, area under curve 0,998 (IK95% 0,994-1,000), serta nilai p <0,001. Kesimpulan: rADC lesi prostat dengan urine dapat membantu diagnosis csPCa dan bukan csPCa pada lesi prostat sebelum biopsi prostat yang tidak invasif, mudah dikerjakan, serta tidak membutuhkan persiapan dan pemeriksaan tambahan.

Background: Clinically significant prostate cancer (csPCa) is prostate cancer with moderate to high probability of local progression, metastasis, recurrence, and death, as well as more aggressive management. This study aims to aid diagnose between csPCa and non-csPCa using apparent diffusion coefficient ratio (rADC) of prostate-lesion-to-urine.

Methods: This study analyze prostate lesions with prostate imaging-reporting and data system category 3-5 that underwent magnetic resonance imaging (MRI)-targeted transperineal prostate biopsy using ultrasound/MRI fusion software at Rumah Sakit Umum Pusat Nasional Dokter Cipto Mangunkusumo from June 2019 to March 2021. rADC of prostate-lesion-to-urine is defined as comparison between mean apparent diffusion coefficient (ADC) value of prostate lesion and urine in urinary bladder from axial section of ADC map of multi-institutional prostate MRI. rADC of prostate-lesion-to-urine between csPCa (acinar adenocarcinoma of the prostate with Gleason score ≥7) and non-csPCa (non-neoplastic prostate tissue or acinar adenocarcinoma of the prostate with Gleason score 6) is compared and the cutoff point is determined using receiver operating curve.

Results: There is significance rADC of prostate-lesion-to-urine difference between 19 prostate lesions with csPCa and 35 prostate lesions with non-csPCa, with mean rADC of prostate-lesion-to-urine in csPCa is 0.21 (0.11-0.33), mean rADC of prostate-lesion-to-urine in non-csPCa is 0.43 (0.30-0.61), and p value is <0.001. The cut-off value of rADC of prostate-lesion-to-urine to differentiate between csPCa and non-csPCa is 0.30, with 94.73% sensitivity and 100% specificity, area under curve is 0.998 (CI95% 0.994-1.000), and p value is <0.001.

Conclusion: rADC of prostate-lesion-to-urine may help diagnose between csPCa and non-csPCa in prostate lesions before prostate biopsy, which is non-invasive, easy to perform, does not require additional preparation and examination."

"Tujuan: Untuk mengetahui bagaimana upaya diagnosis kanker prostat yang dilakukan oleh spesialis urologidi Indonesia. Metode: Dilakukan pembagian kuesioner yang dirancang sendiri kepada Spesialis Urologi di Indonesia. Kuesioner berisi 11 pertanyaan tentang jenis dan indikasi pemeriksaan yang dilakukan, serta fasilitas yang tersedia di tempat responden dalam penegakan diagnosis kanker prostat. Hasil: Sebanyak 65 (36%) dari 182 (saat penelitian ini dilakukan) spesialis urologi di Indonesia mengembalikan formulir kuesioner. Dari jenis RS primer tempat bekerja terbanyak berasal dari RS swasta (35%), disusul RS pendidikan utama Fakultas Kedokteran (32%). Seluruh responden menjadikan lower urinary tract symptoms (LUTS) sebagai indikasi untuk melakukan pemeriksaan colok dubur. Selain itu 83% responden juga menjawab, peningkatan PSA sebagai salah satu indikasi pemeriksaan colok dubur. Pemeriksaan PSA dilakukan oleh 72% responden pada penderita dengan kecurigaan kanker prostat tanpa melihat usia. Sebanyak 66% responden mengerjakan sendiri pemeriksaan transrectal ultrasonografi (TRUS) dan biopsi, 18% merujuk pada sejawat lain di propinsi yang sama dan 15% tidak memiliki fasilitas TRUS dan biopsi di propinsi tempat bekerja. Sebanyak 75% responden memiliki fasilitas bone scan di Rumah Sakit primer, atau tersedia di RS pada propinsi yang sama. Indikasi tersering melakukan biopsi prostat adalah pada PSA lebih dari 10 ng/ml tanpa melihat usia. Sebanyak 86% responden melakukan biopsi pada kecurigaan kanker prostat melalui colok dubur tanpa melihat usia. Sembilan puluh persen responden menggunakan antibiotik profilaksis golongan Kuinolon untuk biopsi prostat. Sebanyak 46% menggunakan analgesia oral atau suppositoria atau kombinasi keduanya sebagai analgesia dalam biopsi prostat. Kesimpulan: Dalam mendiagnosis kanker prostat, spesialis urologi di Indonesia melakukan pemeriksaan colok dubur, PSA dan TRUS biopsi prostat, namun masih terdapat perbedaan pendapat tentang indikasi dan waktu dilakukannya masing-masing pemeriksaan. Ketersediaan fasilitas diagnostik juga berpengaruh dalam diagnostik kanker prostat di Indonesia. Belum tersedianya guideline Nasional pada saat penelitian ini dilakukandiduga menyebabkan perbedaan pendapat tersebut.

Purpose: To get information on diagnosis of prostate cancer conducted by urologist in Indonesia.

Method: A self-constructed questionnare of 11 questions about the type and indication of the tests, as well as the available facilities at the place of the respondents to diagnose prostate cancer distributed to Indonesian Urologist.

Result: As much as 65 (36%) from 182 (when the survey was conducted) Indonesian Urologist returned the questionnare. Most of them worked in Private Hospital (35%), followed by Medical School Hospital (32%). All respondents performed DRE in patients with Lower Urinary Tract Symptoms (LUTS). Elevated PSA was also indication for conducting DRE in 83% respondents. PSA level was tested by 72% respondents in patients with suspicion of prostate cancer regardless of age. As much as 66% respondents did Trans Rectal Ultrasound (TRUS) and prostate biopsy by themselves, 18% referred to other urologists in the same province and 15% didn?t have TRUS and prostate biopsy facilities in their province. Bone scan was available in the Primary Hospital or another hospital in the province of 75% respondents. Main indication to perform prostate biopsy was elevated PSA level above 10ng/ml regardless of the age. Meanwhile, 86% respondents did prostate biopsy in suspiciousness of prostate cancer by DRE regardless of age. Most respondents (90%) chose Quinolon as prophylaxis antibiotic in prostate biopsy and 46% respondents used oral analgesia or suppository or both in prostate biopsy.

Conclusions: In diagnosing prostate cancer, Indonesian Urologists performed DRE, PSA serum analysis and TRUS biopsy of the prostate. But the Indonesian Urologists still had different opinions about the indications and timing of the procedure. The availability of diagnostic equipment and unavailability of National Guideline of Prostate Cancer when this study was conducted played a role of how the prostate cancer diagnosed in Indonesia."
