Objectives: Traditional Korean medicine (TKM) has been supplied as part of a national health care system in South Korea under a dual medical system, however it has been difficult to mix western medicine and TKM medical practices in existing hospitals. For the objective of innovative integration between them, Comprehensive and Integrative Medicine Hospital were founded in Daegu, South Korea. Here, we discussed the clinical outcomes of cancer patients who received integrative cancer treatment (ICT). Methods: A total of 678 patients previously diagnosed with cancer were retrospectively checked in our institution for 2 years. After applying inclusion/exclusion criteria, 573 patients were eligible for the final analysis. The overall survival (OS) of these patients in the aftercare period were determined. We looked at how clinical factors and treatments including chemotherapy, complementary and alternative medicine (CAM), and TKM affected the OS. Results: At the first visit, 212 subjects had no evidence of disease after tumor resection and 355 ones with advanced cancer, who receiving ICT including chemotherapy, CAM, and TKM showed better OS compared to the CAM including TKM or the best supportive care (median OS = 216, 78, and 46 days, respectively). The median OS was not reached in TKM only, even though the sample size was small (N=12). Even after adjusting for clinical factors associated to liver, renal, and hematologic manifestation, ICT still remained significant. Conclusions: We demonstrated that ICT might be beneficial for advanced cancer regardless of the performance status, liver and renal function, since it positively affected the OS.

Unexpected renal abnormality can be detected on bone scan using Tc-99m-MDP. The purpose of the study is to evaluate the diagnostic significance of diffusely increased bliateral renal uptake on bone scarf. 1,500 boor scan were reviewed and 43 scans which showed diffusely increased bliateral renal uptake were selected for analysis. Laboratory findings for renal and liver function tests including routine urinalysis were reviewed in 43 patients. 26 of 43 case showed abnormality in urinalysis and renal function stud 20 of 43 cases showed abnormal liver function study and 3 of these cases were diagnosed as hepatorenal syndrome later. 13 of those 20 cases had liver cirrhosis with or without hepatoma. 12 of 43 cases showed abnormality both in renal and liver function studies. 2 of 43 cases showed diffusely increased bilateral renal uptake after chemotherapy for cancer but not on previous scans before chemotherapy. 2 of 43 cases showed hypercalcemia and 8 of 43 cases had multifocal bone uptake due to metastasis or benign bone lesion. but the latter showed no hypercalcemia at all. There was no significant correlatrion between increased renal uptake and MDP uptake in soft tissue other than kidneys. This study raised the possibility that the impaired liver and/or renal function may result in diffuse increase of bliateral renal uptake of MDP of unknown mechaninsm. It seems to need further study on this correlation.

We need to establish an informative guideline to increase inter-institutional and inter-observer reproducibility of renal transplant diagnosis, and to improve the diagnostic ability of pathologists in Korea. A first nation-wide survey for renal transplant pathology was conducted by Renal Pathology Study Group of the Korean Society of Pathologists in 2016, to provide the continued excellence in the transplantation pathology laboratory, and to improve the diagnostic ability for the best treatment of transplant patients. This survey revealed the significant variations in scale, work load and biopsy indications for the renal transplant pathology in various institutions in Korea. The Banff classification were used by all institutions for the diagnosis of renal transplant pathology, but different formats were used: most institutions (70%) used the "2013 Banff classification" while the others were using "2007 Banff classification" (20%) or even older formats. In daily diagnostic practice of the renal allografts, difficulties that pathologists encounter were quite diverse due to different environments they work in. Most respondents agreed that standardized diagnostic practice guidelines, regular education on renal transplant pathology and convenient ways of consultation are further needed. We are currently working toward the enhancement of the expertise of renal pathologists and to increase inter-institutional and inter-observer reproducibility by 1) development of a set of virtual slides of renal allograft biopsies for the training, 2) validation and gathering expert's consensus on the core variables of rejection diagnosis by using virtual slides, and 3) continued education by the developed virtual slide atlas.

Purpose: Renal cell carcinoma (RCC) is increasingly being recognized as a metabolic disease in recent studies. The aim of the present study was to identify the prevalence of metabolic syndrome (MetS) and its association with RCC among urologic patients. Materials and Methods: The study included a total of 355 participants (117 adult RCC patients and 238 age matched controls) divided into groups, with and without MetS diagnosed using the criteria of the American Heart Association/The National Heart Lung and Blood Institute. Groups were compared statistically and logistic regression analysis was performed to investigate the impact of MetS criteria on RCC risk. Results: Of the 117 RCC patients, 52 (44.4%) and of the 238 controls, 37 (15.5%) had MetS. A significant association (p<0.001) was found between the presence of MetS and RCC (OR: 4.35; 95% CI=2.62-7.21). As the number of MetS components accumulated from 3 to 5, RCC risk increased likewise from 4 to 6 times. Conclusions: MetS is more prevalent in RCC patients in Turkey compared to controls. Risk increases with the number of coexisting MetS components.

Background: Metastatic renal cell carcinoma (mRCC) status as poor prognosis improved with the introduction of tyrosine-kinase inhibitors, especially sunitinib. There is sparse data reporting from our region on use of sunitinib in metastatic RCC. Thus the present study explores sunitinib usage at our institute. Materials and Methods: An unselected population of patients with metastatic RCC receiving sunitinib was analyzed with respect to patient characteristics, response, toxicity, and outcomes. Results: Fourty-nine patients with a median age of 50.5 years (range 21-71 years) were included. Most were male (61.2%). Twenty‑one (42.9%) had metastatic disease at presentation. Sunitinib was first line therapy in 45. Conventional clear cell carcinoma was the most common pathology present (39 patients; 79.59 %). The most common site of metastasis was the lung (75.5%). Most patients (30) were started at a dose of 50 mg once a day for 4 weeks and then 2 weeks rest. Clinical benefit rate was 73.5% (n= 36), and 22.5% (n= 11) demonstrated progressive disease at first imaging evaluation within the first 3-6 months. The following objective response performed for patients was 48.9% (n=24) and progression at 24.5 % (n=12). The median follow‑up was 16 months (range, 4-34 months), the overall estimated median PFS was 9 months and the estimated median OS was 15 months. Conclusions: This study demonstrated sunitinib is tolerable and effective in advanced/metastatic RCC Egyptian patients and indicates we should further seek second and third lines to increase survival equivalence as reported in the worldwide literature.

Background: Retinoblastoma protein-interacting zinc finger gene 1(RIZ1) functions as a tumor suppressor. Hypermethylation-mediated RIZ1 silencing has been reported in several cancers, but not in renal cell carcinoma (RCC) yet. Materials and Methods: We examined the RIZ1 expression and methylation in a panel of RCC cell lines and 50 primary tumors using semiquantitative/quantitative polymerase chain reaction (PCR), methylation specific PCR, and bisulfite sequencing genomic. We also explored the relationship between methylation status of RIZ1 and clinicopathological features in RCC patients. Results: RIZ1 expression was down-regulated or lost in OS-RC-2, 769-P, Caki-1, 786-O and A498 RCC cell lines. Restored expression of RIZ1 was detected after addition of 5-aza-2'-deoxycytidine with/without trichostatin A, suggesting that DNA methylation directly mediates its silencing. The RIZ1 expression was significantly reduced in RCCs compared to adjacent non-malignant renal samples (P<0.001). Aberrant methylation was detected in 15 of 50 (30%) RCCs and in 2 of 28 (7%) adjacent non-malignant renal samples (P=0.02). No statistically significant correlation between methylated and unmethylated cases with regard to age, gender, pathological stage and grade was observed. Conclusions: RIZ1 expression is down-regulated in human RCC, and this down-regulation is associated with methylation. RIZ1 methylation may play a role in renal carcinogenesis.

Objective: To diagnose renal cell carcinoma at early stages and for better prognosis, the main objective of our current study was to understand any association with diabetes with relation to age, gender, history of disease, diabetic laboratory parameters, tumor size and grade. Materials and Methods: This hospital based study was carried out using data retrieved from the register maintained in the Department of Biochemistry of Nepalese Army Institute of Health Sciences between $1^{st}$ December, 2011 and $31^{st}$ May, 2012. The variables collected were age, gender, HbA1c, serum creatinine, fasting blood glucose. One way ANOVA was applied to examine statistical significance of differences between groups. The LSD post hoc test was used for the comparison of means of case groups. Results: Of the total 140 cases of renal cell carcinoma, 79 patients were also suffering from diabetes mellitus. The number of females (47) was more in diabetic RCC patients when compared to males (32). Significance was observed in levels of serum creatinine for tumor size >10cm ($0.0001^*$). The highest value of glycated hemoglobin (8.9%) and fasting blood sugar(148.3mg/dl)in cases of renal cell carcinoma along with diabetes mellitus was found in tumour size of 1-5cm. Conclusion: Diabetes mellitus has independent prognostic significance in RCC in relation to tumour size and grade.

The prolyl 3-hydroxylase family member 4 (P3H4), is associated with post-translational modification of fibrillar collagens and aberrantly activated in cancer leading to tumor progression. However, its role in clear cell renal cell carcinoma (ccRCC) is still unknown. Here we reported that P3H4 was highly expressed in renal cancer tissues and significantly positive correlated with poor prognosis. Knockdown of P3H4 inhibited the proliferation, migration and metastasis of renal cancer cells in vitro and in vivo, and also, overexpression of it enhanced the oncogenic process. Mechanistically, P3H4 depletion decreased the levels of GDF15-MMP9 axis and repressed its downstream signaling. Further functional studies revealed that inhibition of GDF15 suppressed renal cancer cell growth and GDF15 recombinant human protein (rhGDF15) supplementation effectively rescued the inhibitory effect induced by P3H4 knockdown. Moreover, decreased levels of MMP9 caused by inhibition of P3H4-GDF15 signaling constrained the expression of PD-L1 and suppression of P3H4 accordingly promoted anti-tumor immunity via stimulating the infiltration of CD4+ and CD8+ T cells in syngeneic mice model. Taken together, our findings firstly demonstrated that P3H4 promotes ccRCC progression by activating GDF15-MMP9-PD-L1 axis and targeting P3H4-GDF15-MMP9 signaling pathway can be a novel strategy of controlling ccRCC malignancy.
