Blood Transfusions in Laparoscopic Living Donor Nephrectomy: Single Center Experience from 500 Cases.

INTRODUCTION: Laparoscopic surgery has been acknowledged to reduce the morbidity rate thus improving patient safety. During the LLDN, the most frequent complication is renal vessels injuries, which often requires a blood transfusion. Besides the need for a blood transfusion, major bleeding caused by renal vessels injuries requires open conversion and repair. Thus, this study would like to descript and analyze the need for blood transfusion in laparoscopic living donor nephrectomy surgery in our center. METHODS: We performed a retrospective cohort study in the Department of Urology at Cipto Mangunkusumo National Hospital. The records of all kidney transplantation donor patients who underwent LLDN procedures carried out at our institution from November 2011 to October 2017 were reviewed. Data including donor age, preoperative hemoglobin level, postoperative hemoglobin level, intraoperative bleeding, number of artery(ies), number of vein(s), donor side, conversion to open surgery, surgery duration, and donor BMI were collected and analyzed. These data were further correlated with the transfusion rate. RESULTS: There were 500 patients underwent laparoscopic living donor nephrectomy procedure at our institution. All of the patients had LLDN with a transperitoneal approach. The difference in blood transfusion rate proportion between male patients with 0.9% compared to 0.6% in female patients was not significant (p=0.782). There is no significant difference in blood transfusion rate proportion regarding renal side (p=0.494), number of artery (p=0.362), age (p=0.978), BMI (p=0.569), and preoperative hemoglobin (p=0.766). Median estimated blood loss in patients who received intraoperative blood transfusion was significantly much greater than in patients who did not receive a blood transfusion (p<0.001). CONCLUSION: Based on this study, we suggest that in our institution, preoperative blood products are not necessarily needed. The surgeon's learning curve and technique play a significant role in preventing intraoperative complications and blood loss.

Survival analysis and development of a prognostic nomogram for bone-metastatic prostate cancer patients: A single-center experience in Indonesia.

OBJECTIVES: To analyze predictive clinical factors of survival in bone-metastatic prostate cancer, and to develop a prognostic nomogram for patients with this condition. METHODS: The present study included 392 patients with bone-metastatic prostate cancer treated with androgen deprivation therapy. Pretreatment parameters were analyzed using the Cox proportional hazards model to identify the predictors of overall survival. Covariates - which showed statistical significance on multivariate analysis - were used to develop a nomogram. A linear predictor model was utilized to develop the nomogram. RESULTS: The median overall survival was 40.3 months (95% confidence interval 32.2-48.5). Univariate analysis showed that clinical T stage, Gleason score, initial prostate-specific antigen value and the number of metastatic lesions were independent prognostic factors for overall survival. These predictors remained significant as independent prognostic factors for overall survival after analysis using the multivariate Cox regression model. The nomogram constructed from those prognostic factors showed good discrimination for predicting the 5-year overall survival, with an area under the curve of 0.69. Acceptable agreement of the observed and predicted probabilities was observed in the calibration plot. CONCLUSIONS: The present prognostic nomogram might be a useful tool for predicting overall survival in pretreatment bone-metastatic prostate cancer, specifically among Indonesian patients. Further studies are required to provide external validation to support the utilization of this nomogram.

The Risk Factors of Prostate Cancer and Its Prevention: A Literature Review.

This is a literature review study. Data was obtained from several literature reviews and journal resources that have correlation with the risk factors involved in PCa including age, ethnicity, family history, insulin-Like growth factor, sexually transmitted disease, obesity, smoking, alcohol consumption, vasectomy, and diet, and the prevention of PCa including soy, lycopene, green tea, supplementation, and exercise.Numerous epidemiologic studies have linked PCa risk to various factors, i.e. age, ethnicity, family history, insulin like-growth factors, lifestyle, diet, environmental and occupational exposures. The results of epidemiological, In vivo, in vitro, and early clinical studies suggested that selected dietary products and supplementation may play a role in PCa prevention. More studies are still needed to explore and find the risk factors and preventive methods of PCa development. It is important for clinician to ellaborate these informations for education to lower PCa risks and prevent PCa.

Targeted Therapy for Metastatic Renal Cell Carcinoma.

In the past 10 years, recent development of targeted therapy in metastatic renal cell carcinoma (mRCC) has provided a new hope and significantly enhanced the prognosis of the disease. Three class of targeted therapy were developed, including multi-targeted tyrosine kinase inhibitors (TKI), the mammalian target of rapamycin (mTOR) complex-1 kinase inhibitors, and the humanized antivascular endothelial growth factor (VEGF) monoclonal antibody. Hence, the objective of this article was to critically examine the current evidence of targeted therapy treatment for patients with mRCC. In the majority of trials evaluating targeted therapy, patients were stratified according to Memorial Sloan Kattering Cancer Center (MSKCC) risk model and the recommendation of targeted treatment based on risk features. In first-line setting (no previous treatment), sunitinib, pazopanib, or bevacizumab plus IFN-α were recommended as treatment options for patient with favorable- or intermediate- risk features and clear cell histology. Patients who progressed after previous cytokine therapy would have sorafenib or axitinib as treatment options. Clear-cell mRCC with favorable- or intermediate- risk features and failure with first-line TKI therapy might be treated with sorafenib, everolimus, temsirolimus or axitinib. However, the current evidence did not show the best treatment sequencing after first-line TKI failure. In patients with poor-risk clear-cell and non-clear cell mRCC, temsirolimus was the treatment option supported by phase III clinical trial. In addition, several new drugs, nowadays, are still being investigated and waiting for the result of phase II or III clinical trial, and this might change the standard therapy for mRCC in the future.

Metastasis of testicular carcinoma in the inguinal region.

A standard protocol for the management of inguinal metastasis from testicular cancer still has not yet been established. Metastasis of testicular cancer to inguinal lymph node rarely occurs, particularly in patients without any prior surgery in inguinal and scrotal region. Daugaard reported 2% incidence of inguinal metastasis for stage 1 testicular cancer in 5-year period. We reported a case of inguinal metastasis from residual testicular cancer with a large size of mass. The case had also been counted as advanced stage since it had further metastasis to the lungs. For this case, surgical treatment of residual tumor excision had been performed prior to the chemotherapy considering a quite large size of tumor mass, which may easily bleed and causing anemia to the patient. Furthermore, we considered that chemotherapy treatment prior to surgical excision will only provide partial effect on the tumor. After the surgery, a 4-cycle combined chemotherapy was administered despite the delay of chemotherapy treatment resulting in residual mass in inguinal region. In fact, the post-surgical chemotherapy treatment in this case has demonstrated relatively good response.
