BACKGROUNDThe coagulation function in carcinoma patients is abnormal, but in renal cell carcinoma the extent and relationships of coagulation function remain unclear. This study retrospectively investigated the relationships between coagulation function, clinical stage and metastasis in patients with renal cell carcinoma.

METHODSA total of 350 consecutive patients admitted to our Urology Department from 2004 to 2010 were diagnosed with renal cell carcinoma by histopathologic examination and were included in this study. A total of 231 cases of renal benign tumors were considered as the control group. Fibrinogen, prothrombin time, activated partial thromboplastin time and international normalized ratio were evaluated in all subjects. Tumor size, clinical stage, lymph node metastasis, and distant metastasis were evaluated using radiologic imaging, intraoperative findings, and histological studies.

RESULTSThe preoperative plasma fibrinogen levels of patients with renal cell carcinoma ((383.9 ± 146.7) mg/dl) were significantly higher than those of the control group ((316.7 ± 62.0) mg/dl) (P < 0.01). We divided the renal cell carcinoma group into stages Ia, Ib, II, III, and IV. The fibrinogen values were (315.6 ± 64.6) mg/dl, (358.3 ± 91.1) mg/dl, (465.6 ± 164.7) mg/dl, (500.0 ± 202.1) mg/dl, and (585.8 ± 179.7) mg/dl, respectively. There were no significant differences in fibrinogen values between stage Ia and control groups. However, results of other stages showed significant differences when compared to control group values (P < 0.01). Using the cutoff value of 440 mg/dl, which defines hyperfibrinogenemia, plasma fibrinogen levels had a positive predictive value of 39.8% and a negative predictive value of 93.3% for predicting distant metastasis, with a sensitivity of 64.7% and specificity of 83.3%.

CONCLUSIONSPreoperative plasma fibrinogen levels are elevated in patients with renal cell carcinoma with distant metastasis or lymph node metastasis. Potential metastasis is more likely if the tumor size larger than 4 cm. Increased preoperative plasma fibrinogen levels, especially hyperfibrinogenemia, may be an indicator of metastasis.

OBJECTIVETo evaluate the alterations in renal function after radical nephrectomy (RN) and partial nephrectomy (PN) for renal cell carcinoma (RCC) and to determine the risk factors for the onset of postoperative renal function impairment.

METHODSWe assessed the renal function of 429 T1a RCC patients by investigating the time-dependent changes of the estimated glomerular filtration rate (eGFR) after surgery from August 2003 to August 2010. Univariate and multivariate regression models were used to determine the risk factors for the onset of an eGFR < 60 ml · min⁻¹ · 1.73 m⁻² function, and to evaluate the prognosis for the two groups.

RESULTSThe mean eGFR values (ml · min⁻¹ · 1.73 m⁻²) at postoperative 1, 7 days, 1, 3, 6, 12 and 24 months were 51.4 ± 12.6, 52.1 ± 17.8, 53.2 ± 19.5, 54.6 ± 20.2, 53.8 ± 16.6, 52.7 ± 22.3 and 51.5 ± 18.4 in the RN group and 69.6 ± 18.3, 70.3 ± 19.5, 71.5 ± 21.4, 76.2 ± 22.8, 75.4 ± 19.7, 74.3 ± 16.3 and 73.1 ± 23.2 in the PN group, respectively. The eGFR of the radical nephrectomy group was significantly lower than that of the partial nephrectomy group (P < 0.05). Multivariable analysis revealed that radical nephrectomy and age were risk factors for the onset of postoperative chronic renal dysfunction.

CONCLUSIONSRenal function recovered partially after partial and radical nephrectomy and is maintained constantly after 3 months. Surgical mode and age are risk factors for the onset of postoperative eGFR < 60 ml · min⁻¹ · 1.73 m⁻² impairment. Compared with radical nephrectomy, partial nephrectomy can preserve renal function and reduce the incidence of postoperative chronic renal dysfunction.

OBJECTIVETo investigate the factors regarding the recovery of postoperative blood pressure of aldosterone producing adenoma (APA) patients.

METHODSSixty-eight patients with APA were recruited and their data including retinal blood vessel by Doppler sonography, urinary trace albumin, pathological changes of renal biopsy and the adrenal tissues around the adenoma were analyzed in order to determine the correlation between these data and postoperative durative hypertension.

RESULTSPostoperative durative hypertension occurred in 14 cases (41.2%) with increased resistance of unilateral or bilateral central artery of retina, in 16 cases (66.7%) with increased level of urinary trace albumin. Fifteen cases underwent renal biopsy and all of them showed different pathological alterations, 11 cases (73.3%) of which presented with postoperative durative hypertension. The pathological changes of the adrenal tissues around the adenoma is either atrophy or non-atrophy (normal or hyperplasia), 8 cases (40%) and 10 cases (22.2%) of which showed postoperative durative hypertension, respectively.

CONCLUSIONThe renal pathological changes and increased resistance of retinal blood vessel are the main reasons leading to postoperative hypertension in patients with APA.

This study was done to analyze the clinical characteristics of renal cell carcinoma (RCC) in Korean patients with von Hippel-Lindau (VHL) disease. Between January 1996 and July 2008, 1,514 patients were diagnosed with RCC and 24 patients were diagnosed with VHL disease at our institute. We analyzed the clinical characteristics of the 24 patients diagnosed with VHL. The mean age of patients with VHL was 39.2+/-12.6 yr; the mean age of patients with both VHL and RCC was 42.5+/-10.3 yr. Among the 24 patients with VHL, 7 patients had retinal angiomas, 11 had RCC, 16 had renal lesions, 18 had pancreatic lesions and 21 had cerebellar hemangioblastomas. There was no significant difference between survival rates of patients with VHL alone and those with VHL and RCC. However, cancer-specific survival rates were significantly different between patients with both VHL and RCC and patients with sporadic bilateral or multifocal RCC. In our Korean study, the incidence of RCC in patients with VHL disease is 45.8% and the incidence of VHL disease in patients with RCC is 0.73%. Due to the low overall incidence of VHL in Korea, extended multi-institutional studies are needed to establish the true characteristics of VHL disease.

This article provides an overview of metastases to jaws (MJ), mainly concerning the differences between American and Chinese patients, and exploring the relationship between the primary tumors' prevalence (PTP) and constituent ratio of MJ. Information concerning of 399 MJ cases in 215 papers, including one new case in our hospital, was subjected to statistic analysis. The main clinical features of MJ, such as constituent ratio of PTP and that of MJ, metastatic sites, treatments, and prognosis were summarized. Breast, lung, kidney, prostate and thyroid (in descending order) were the leading primary sites of MJ. Furthermore, the constituent ratio of MJ was found to be correlated with that of PTP in all subjects including American and Chinese subjects in our study. As to metastatic sites in the mandible, a specific "M" shaped pattern appeared regardless of the tumor type or constituent ratios of MJ were in all subjects. Almost all subjects received traditionally palliative treatments, and the prognosis was quite poor. The PTP had a significant impact on the constituent ratio of MJ. However, it was the properties of the microenvironment rather than characteristics or constituent ratios of tumor cells, that decided the metastatic sites in various tumor subjects.

OBJECTIVETo observe the protective effect of ginsenosides (GS) or low dose of glucocorticoid dexamethasone (Dex) alone or combined in managing the liver injury and renal function after transcatheter arterial chemoembolization (TACE).

METHODS120 patients with primary liver carcinoma were randomly divided into four groups (A, B, C, D) with 30 patients in each. Group A was treated with placebo; group B with Dex; group C with GS and group D with Dex plus GS. The changes in liver and renal function after TACE were observe according to the WHO criteria for side effects of anti-cancer drug.

RESULTSCompared with group A, Dex combined with GS was able to reduce the level of TB, ALT/AST, BUN and Child-grade, which significantly protected the liver and kidney (P < 0. 05). However, Dex or GS alone could also improve some parameters of liver and renal function after TACE (P < 0.05).

CONCLUSIONDex combined with GS is effective in managing the liver injury and renal function after transcatheter arterial
