Purpose:Racial differences exist in the incidence of prostate cancer (PCa). Although many studies have looked at the performance of prostate-specific antigen (PSA) and PSA density (PSAD) in the detection of PCa, only a few have looked at it in relation to Indonesian men. The objective of this study is to find out better PSA and PSAD cutoff point in the detection of PCa in Indonesian men.Methods:A total of 404 consecutive Indonesian men underwent prostate biopsy for suspicion of PCa from 2008 to 2011. The biopsy criteria include one or more of the following: serum PSA more than 10 ng/mL, PSAD more than 0.15 if PSA 4–10 ng/mL, hypoechoic lesion during transrectal sonography and/or abnormal digital rectal examination.Results:Forty five out of 404 (11.1%) had positive biopsies. The mean age, prostate volume, PSA and PSAD were respectively 64.06 years, 43.03 mL, 45.59 ng/mL and 1.15. Of the 404, 131 cases (32.4%) were confirmed to be urinary retention. Positive urine culture found in 182 cases (45%). The cutoff point to detect PCa as estimated by the receiver operating characteristics was 6.95 ng/mL for PSA (sensitivity 97.8%, specificity 19.6%) and 0.7072 for PSAD (sensitivity 62.2%, specificity 78.7%). Positive predictive value for this PSA and PSAD cutoff point were 11.6% and 27.5% respectively (P=0.004 and P=0.000). There was a significant correlation between hypoechoic lesion and positive biopsy results (P =0.000). Urinary retention elevates PSA cutoff point to 14.55 (sensitivity 90.9%, specificity 50%), while positive urine culture alters almost no PSA cutoff elevation.Conclusions:PSA and PSAD cutoff point for Indonesian men in this series is relatively different from international consensus. Furthermore, these data show that PSA and PSAD cutoff point must be adjusted to racial variation to discriminate between malignant and benign disease. Urinary retention is a significant factor for PSA cutoff increase.
Non-communicable diseases, including cancer, start to become more common in Indonesia. According to the government statement, incidence of malignant diseases increased annually up to 8% in the last decade and these diseases become the seventh leading cause of death in Indonesia. On the basis of the latest Globocan report on cancer incidence in Indonesia, prostate cancer ranks sixth; followed by bladder (12th) and kidney (18th). More than half of patients with kidney cancer are diagnosed in the advanced stage. Besides renal cell carcinoma, there are significant number of people affected with squamous cell and transitional cell carcinoma because of kidney stones. Radical nephrectomy or cytoreductive nephrectomy was the primary treatment, mostly done as an open procedure. Transitional cell carcinoma is the commonest histology type in bladder cancer cases followed by squamous cell carcinoma, which almost always related to bladder stones. Unfortunately, >70% of our cases were diagnosed with muscle invasive bladder cancer, and ∼60% of these patients refused further radical treatment. Incidence of prostate cancer is increasing rapidly and it becomes the third most common cancer in men. However, most of our patients are diagnosed in the advanced stage. Radical prostatectomy or external beam radiotherapy is the treatment of choice in localized disease. Nearly 40% of the elderly patients are treated with primary androgen deprivation therapy. Therefore, it requires more research by the Indonesian urologists and other healthcare providers to diagnose these cancers in earlier stage as well as community education for prevention.
Bladder migration and transurethral extrusion is an extremely rare complication of ventriculoperitoneal (VP) shunt. Only eight cases have been reported in the English literature since 1995. We report a case of a 4-year-old boy with cerebral palsy, hydrocephalus, and VP shunted on both sides who presented with a protruded distal VP shunt from his urethral orifice. The patient was reported for having previous shunt extrusion through the anus. The patient was treated on by a multidisciplinary approach, involving a neurosurgeon and urologist. Shunt removal with simple procedure was smoothly achieved without morbidities. He was discharged home in satisfactory condition.
Background: Multiple primary malignancies (MPMs), especially coexistence of renal cell carcinoma (RCC) and glioblastoma multiforme (GBM), are rare. The most likely clinical diagnosis in patient with tumor in another organ is metastatic brain tumor. Although GBM is the most common brain tumor, it is rarely coexistent with other malignancies. Case Description: A 64-year-old female presented with headache and dizziness, along with abdominal pain for 2 weeks before being admitted. The abdominal computed tomography (CT) scan showed a kidney tumor. The patient developed left hemiplegia, and the brain CT scan showed an intracranial tumor. The patient suggested for radical nephrectomy and craniotomy tumor removal. Histopathology of the kidney and brain tumor revealed two different features, which showed RCC and GBM. Immunohistochemistry result confirmed the diagnosis of GBM and IDH1 wild type; coexistent with clear cell RCC. Conclusion: The coexistence of carcinoma and glioma should be regarded as coincidental cases if it did not accomplish the criteria for tumor-to-tumor metastasis or proven to be a genetic syndrome. This case report provides an addition to the literature about double primary malignancy in a single patient. More studies are needed to confirm whether they have causal relationship or merely coincidental findings.
Colocutaneous fistula with nephrocutaneous fistula is a rare condition. Renal replacement lipomatosis is the result of the atrophy and destruction of renal parenchyma. We report a 60-year-old male with intermittent drainage mucus and fluid from ulcer of his right lumbar region. Renal ultrasound and plain abdominal X-ray revealed a chronic parenchymal disease with stone of the right kidney. Fistulography showed a fistula tract connecting the skin and the right pelvicalyceal system and the colon. Computerized tomography demonstrated a renal calculus with a massive fatty proliferation. The patient was planned for right nephrectomy and excision of the sinus tract.
