RESUMO
Purpose@#Outcome analysis of urachal cancer (UraC) is limited due to the scarcity of cases and different staging methods compared to urothelial bladder cancer (UroBC). We attempted to assess survival outcomes of UraC and compare to UroBC after stage-matched analyses. @*Materials and Methods@#Total 203 UraC patients from a multicenter database and 373 UroBC patients in single institution from 2000 to 2018 were enrolled (median follow-up, 32 months). Sheldon stage conversion to corresponding TNM staging for UraC was conducted for head-to-head comparison to UroBC. Perioperative clinical variables and pathological results were recorded. Stage-matched analyses for survival by stage were conducted. @*Results@#UraC patients were younger (mean age, 54 vs. 67 years; p < 0.001), with 163 patients (80.3%) receiving partial cystectomy and 23 patients (11.3%) radical cystectomy. UraC was more likely to harbor ≥ pT3a tumors (78.8% vs. 41.8%). While 5-year recurrence-free survival, cancer-specific survival (CSS) and overall survival were comparable between two groups (63.4%, 67%, and 62.1% in UraC and 61.5%, 75.9%, and 67.8% in UroBC, respectively), generally favorable prognosis for UraC in lower stages (pT1-2) but unfavorable outcomes in higher stages (pT4) compared to UroBC was observed, although only 5-year CSS in ≥ pT4 showed statistical significance (p=0.028). Body mass index (hazard ratio [HR], 0.929), diabetes mellitus (HR, 1.921), pathologic T category (HR, 3.846), and lymphovascular invasion (HR, 1.993) were predictors of CSS for all patients. @*Conclusion@#Despite differing histology, UraC has comparable prognosis to UroBC with relatively favorable outcome in low stages but worse prognosis in higher stages. The presented system may be useful for future grading and risk stratification of UraC.
RESUMO
Purpose@#This study aimed to determine the prognostic roles of several immune-related laboratory parameters in patients with metastatic kidney and bladder cancer treated with immune checkpoint inhibitors (ICIs). @*Materials and Methods@#Overall, 36 patients with either metastatic bladder (N=18) or kidney cancer (N=18) were enrolled retrospectively. Progression-free survival (PFS) and overall survival according to the pretherapeutic serum De Ritis ratio (DRR), neutrophil-to-lymphocyte ratio (NLR), and albumin level after ICI treatment, were analyzed. Treatment duration was adjusted using Contal and O’Quigley’s method to explore the cutoff and maximize the log-rank test statistic. Cox proportional hazards model was used to analyze the laboratory parameters. @*Results@#A total of 9 patients received a combination therapy of multiple ICIs (N=9) and targeted agents (N=7). The median NLR, DRR, and albumin level at baseline were 1.7, 1.2, and 4.2 mg/dL, respectively. In the univariable analysis, combination of immunotherapies, total ICI cycles, baseline DRR, and albumin level were significant for PFS. Sex ratio, total ICI cycles, and baseline NLR and DRR were significant for cancer-specific survival (CSS). DRR and albumin levels, which were measured for up to 10 cycles, were significant in PFS and CSS. NLR was additionally significant in CSS. After adjusting total ICI cycles, DRR was significant in PFS and CSS, albumin level was significant only in PFS, and NLR was significant only in CSS in the multivariable analysis. @*Conclusions@#NLR, DRR, and albumin level are significant factors associated with the survival of patients with metastatic kidney and bladder cancer treated with ICI.
RESUMO
Even with advances in perioperative medical care, anesthetic management, and surgical techniques, radical cystectomy (RC) which remains the gold standard therapy for the treatment of muscle-invasive bladder cancer, yet is still associated with a high morbidity rate as well as a prolonged length of hospitalization (LOH). Recently, there has been a great deal of interest in developing multimodal and multidisciplinary strategies that might aid in the acceleration postoperative convalescence by decreasing variance in perioperative care for patients having complex operations. Many patient series have shown that Enhanced Recovery After Surgery (ERAS) protocols can improve outcomes in patients having RC by reducing the incidence of gastrointestinal complications and the LOH without increasing readmissions or overall morbidity. Many studies are going to evaluate and incorporate scientific data in ERAS program to modify as many of the variables leading to RC morbidity, as well as to enhance how patients are cared for before and after operation. In this review, we offer a summary of the preoperative, intraoperative, and postoperative key components of undergoing an ERAS protocol for patients undergoing RC, as well as future research prospects.
RESUMO
Radical cystectomy (RC) is the gold standard treatment option for muscle invasive bladder cancer (MIBC). However, up to 25% of patients who undergo RC show metastatic lymph node deposits during the procedure. In such cases, the 5-year survival rate is reported to be 25%–30%. Pelvic lymph node dissection (PLND) can also provide useful prognostic information, including data regarding the disease burden, lymph node density, and extracapsular extension of metastatic lymph nodes. Accordingly, the National Comprehensive Cancer Network guidelines recommend that PLND that includes the common iliac lymph node should be performed at the time of RC to allow reliable staging of MIBC. In addition to its diagnostic role, many studies have reported the potential therapeutic role of PLND. Data from clinical trials indicate a substantial oncological advantage in PLND cohorts compared to non-PLND cohorts, regardless of pathological nodal status, as a result of removal of metastatic and micrometastatic tumor cells nested in lymph nodes. As such, despite the diagnostic and therapeutic role of PLND in MIBC, the optimal PLND template remains controversial. Currently, extended PLND (E-PLND) is recommended for diagnostic purposes, however, E-PLND did not show therapeutic effectiveness in some recent preliminary randomized controlled trials. In this review, we will discuss the appropriate range of PLND for RC in terms of its diagnostic and therapeutic importance, and propose an appropriate range of PLNDs based on the evidence and randomized trials so far.
RESUMO
Purpose@#This study aimed to analyze the overall survival (OS) in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with either combination or only secondary hormone therapy (2ndHTx) or docetaxel chemotherapy. @*Materials and Methods@#Between 2005 and 2018, 307 mCRPC patients’ medical records were retrospectively reviewed treated with either 2ndHTx (HTx [N=73, 23.8%] either abiraterone acetate or enzalutamide), docetaxel+2ndHTx (CTx-HTx [N=90, 29.3%]) or only docetaxel therapy (CTx-only [N=144, 46.9%]). The Cox proportional hazard model for risk factors of OS and Kaplan-Meier analysis with log-rank test for OS comparison among three therapeutic groups with a statistical significance of p<0.05. @*Results@#During a median 49.6-month follow-up and a median 22 months of OS, the worst OS was observed in CTx-only (17.7 months) followed by the CTx-HTx (22.9 months), and only-HTx (42.6 months) groups (p<0.001). The baseline comparison showed that age, body mass index, TN stagings, and prostate specific antigen level were significantly different between groups (p<0.05). In the multivariable analysis for the risk factors of OS, age (hazard ratio [HR], 0.978), cT3–4 stage (HR, 1.606), and HTx (HR, 0.482) were significant factors. With the HTx agents, enzalutamide was the only left risk factor for OS regardless of underlying diseases (HR, 0.511; p<0.001). The group analyses for the OS showed that only-CTx group (HR, 2.696) and CTx-HTx group (HR, 1.434) were unfavorable factors for OS with a reference of HTx group (p<0.001). @*Conclusions@#2ndHTx was a significant prognostic factor for OS regardless of underlying diseases in patients with mCRPC and improved OS in comparison with docetaxel.
RESUMO
Current standard diagnostic modality of bladder cancer is cystoscopy with/without urine cytology from patient’s voided urine. Considering several cystoscopic disadvantages such as symptomatic invasiveness and operatordependency, urinary cytology is an asymptomatic, noninvasive tool to detect exfoliated tumor cell in the urine samples. Various targeting molecules have been suggested to detect cancer cells in the urine beside the present urine cytology which has a limited diagnostic power of detection cancer cells. To augment the accuracy of diagnostic power, various supplementary urine biomarkers have been approved and under investigation in these days with different mechanisms and different targets. In this review article, we are going to discuss some urinary biomarkers approved by the U.S. Food and Drug Administration (FDA) and other non-FDA approved potential urinary markers in bladder cancer.
RESUMO
Purpose@#The purpose of this study was to identify prognostic tissue markers for several survival outcomes after radical nephroureterectomy among patients with upper urinary tract urothelial carcinoma using tissue microarray and immunohistochemistry. @*Materials and Methods@#Retrospectively, data of 162 non-metastatic patients with upper urinary tract urothelial carcinoma after radical nephroureterectomy between 2004 and 2016 were reviewed to determine intravesical recurrence-free survival (IVRFS), disease-free survival (DFS), and overall survival (OS). The expression of 27 tissue markers on a tissue microarray of radical nephroureterectomy samples and prognostic values of clinicopathological parameters were evaluated using immunohistochemistry and Cox proportional hazard models after adjusting for significant prognostic clinicopathological variables. The expression of all tissue markers was categorized into a binary group with continuous H-scores (0-300). @*Results@#Median follow-up was 53.4 months (range, 3.6 to 176.5 months); and, 58 (35.8%), 48 (29.6%), and 19 (11.7%) bladder recurrence, disease progression, and all cause death, respectively, were identified. After adjusting for significant clinicopathological factors including intravesical instillation for bladder recurrence-free survival, pathologic T category and intravesical instillation for disease progression-free survival , and pathologic T category for OS (p < 0.05), IVRFS was associated with epithelial cadherin (hazard ratio [HR], 0.49), epidermal growth factor receptor/erythroblastosis oncogene B (c-erb) (HR, 2.59), and retinoblastoma protein loss (HR, 1.85); DFS was associated with cyclin D1 (HR, 2.16) and high-molecular-weight cytokeratin (HR, 0.42); OS was associated with E-cadherin (HR, 0.34) and programmed cell death 1 ligand (HR, 13.42) (p < 0.05). @*Conclusion@#Several significant tissue markers were associated with survival outcomes in upper urinary tract urothelial carcinoma patients treated with radical nephroureterectomy.

RESUMO
PURPOSE: We compared oncologic outcomes of patients with upper tract urothelial carcinoma (UTUC) who underwent open nephroureterectomy (ONU) or laparoscopic nephroureterectomy (LNU). MATERIALS AND METHODS: Consecutive cases of ONU and LNU between 2000 and 2012 at five participating institutions were included in this retrospective analysis. Clinical characteristics and pathologic outcomes were compared between the two surgical approaches. The influence of the type of surgical approach on intravesical recurrence-free survival (IVRFS), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) was analyzed using the Kaplan-Meier method and differences were assessed with the log-rank test. Predictors of IVRFS, PFS, CSS, and OS were also analyzed with a multivariable Cox regression model. RESULTS: A total of 1,521 patients with UTUC were eligible for the present study (ONU, 906; LNU, 615). The estimated 5-year IVRFS (57.8 vs. 51.0%, p=0.010), CSS (80.4 vs. 76.4%, p=0.032), and OS (75.8 vs. 71.4%, p=0.026) rates were significantly different between the two groups in favor of LNU. Moreover, in patients with locally advanced disease (pT3/pT4), the LNU group showed better 5-year IVRFS (62.9 vs. 54.1%, p=0.038), CSS (64.3 vs. 56.9%, p=0.022), and OS (60.4 vs. 53.1%, p=0.018) rates than the ONU group. Multivariable Cox regression analyses showed that type of surgical approach was independently associated with IVRFS, but was not related to PFS, CSS, and OS. CONCLUSION: Our findings indicate that LNU provided better oncologic control of IVRFS, CSS, and OS compared with ONU for the management of patients with UTUC.

PURPOSE: The lower incidence of bladder cancer among women has led to a lack of information on female radical cystectomy (RC). This study aimed to analyze the characteristics related with female RC in a cohort from multiple academic institutions. MATERIALS AND METHODS: This was a retrospective review of 384 female patients who underwent RC for bladder cancer. Epidemiologic, perioperative variables including urologic referral periodwith consequent pathologic stage distributions were assessed. The changes in surgical techniques over time were illustrated. Also, we evaluated recurrence-free survival (RFS) at 2 and 5 years and overall survival (OS) at 5 years with stage-specific analyses using the Kaplan-Meier method. RESULTS: The mean follow-up time was 35 months (interquartile rage [IQR], 9 to 55). The average time to urologic referral with initial symptoms was 5.5 (IQR, 1 to 6) months and over 20% of patients visited clinics after 6 months. In subsequent stage distributions according to referral period, T2 or higher stage distributions were abruptly increased after 1 year. Overall 2-year/5-year RFS rates were 0.72/0.57 and 5-year OS was 0.61. Notable surgical descriptions were as follows: 91% of patients underwent open RC; 80% of patients underwent an ileal conduit; and 83% of patients received anterior exenteration. However, the proportions of robotic surgery, orthotopic neobladder and organ sparing cystectomy have increased recently. CONCLUSION: We identified the general characteristics and changes in pattern of female RC. Our results also suggest that women are susceptible to delays in referral to an urologist and are at greater risk for worse prognosis.

PURPOSE: The purpose of this study was to compare oncologic outcomes between open nephroureterectomy (ONU) and laparoscopic nephroureterectomy (LNU) in patients with upper tract urothelial carcinoma. MATERIALS AND METHODS: The medical records of consecutive ONU and LNU cases from five tertiary institutions were retrospectively analyzed between 2000 and 2012. The propensity-score matching methodology was used to compare the two surgical approaches in terms of age, body mass index, American Society of Anesthesiologists score, tumor location, grade, pathologic T and N categories, the presence of lymphovascular invasion, and follow-up duration. The Kaplan-Meier with log-rank tests and clustered Cox regression were used to compare the estimated rates of survival for each surgical approach and to investigate the effect of the surgical approach on each prognostic outcome. RESULTS: Six hundred thirty-eight propensity-score matching pairs (n=1,276) were compared; LNU was significantly better than ONU in all types of survival, including intravesical recurrence-free survival (IVRFS), disease-free survival, overall survival (OS), and cancer-specific survival (CSS) (p < 0.05). The 3-year OS and CSS rates were significantly higher with LNU than with ONU (p < 0.05). Compared with ONU, LNU had significantly better 3-year OS and CSS rates (82.9% and 86.2% vs. 78.3% and 81.8%); there were no differences at 5 years. In subgroup analysis of the early-staged group, advanced-stage group, lymph node–positive group, and lymph node–negative group, the two approaches did not significantly affect prognostic outcomes, except LNU improved the IVRFS in the lymph node–negative or no history of previous bladder cancer group. CONCLUSION: LNU had a significantly better prognostic outcome than ONU after propensity-score matching.

PURPOSE: The purpose of this study was to determine whether histologic inflammation (HI) in initial and repeat prostate biopsy specimens was significantly associated with the detection of prostate cancer. MATERIALS AND METHODS: Between 2005 and 2017, the clinicopathological records of patients with high prostate-specific antigen (PSA) levels who underwent initial and repeat prostate biopsies were retrospectively reviewed. The presence of HI and its degree in each biopsied specimen were interpreted by one uropathologist with 20 years of experience. The association between HI and cancer diagnosis was statistically assessed, with p 0%) on biopsied specimens, respectively. Comparison of the cancer and noncancer groups revealed that a greater rate of HI specimens in the initial biopsy was associated with fewer prostate cancer diagnoses following repeat biopsy (p < 0.001). Other comparisons between the cancer and non-cancer groups showed that the cancer group had a significantly higher rate of hypertension, whereas those non-cancer group had a significantly higher rate of benign prostatic hyperplasia and prostatitis (p < 0.05). CONCLUSION: A finding of a lesser degree of HI in the initial and a greater degree of HI in the repeat biopsied specimens was associated with the higher probability of cancer diagnosis in patients with high PSA levels.

PURPOSE: The use of prostate-specific antigen as a biomarker for prostate cancer (PC) has been controversial and is, therefore, not used by many countries in their national health screening programs. The biological characteristics of PC in East Asians including Koreans and Japanese are different from those in the Western populations. Potential lifestyle risk factors for PC were evaluated with the aim of developing a risk prediction model. MATERIALS AND METHODS: A total of 1,179,172 Korean men who were cancer free from 1996 to 1997, had taken a physical examination, and completed a lifestyle questionnaire, were enrolled in our study to predict their risk for PC for the next eight years, using the Cox proportional hazards model. The model’s performance was evaluated using the C-statistic and Hosmer–Lemeshow type chi-square statistics. RESULTS: The risk prediction model studied age, height, body mass index, glucose levels, family history of cancer, the frequency of meat consumption, alcohol consumption, smoking status, and physical activity, which were all significant risk factors in a univariate analysis. The model performed very well (C statistic, 0.887; 95% confidence interval, 0.879 to 0.895) and estimated an elevated PC risk in patients who did not consume alcohol or smoke, compared to heavy alcohol consumers (hazard ratio [HR], 0.78) and current smokers (HR, 0.73) (p < 0.001). CONCLUSION: This model can be used for identifying Korean and other East Asian men who are at a high risk for developing PC, as well as for cancer screening and developing preventive health strategies.

PURPOSE: Secondary primary cancers (SPCs) commonly arise in patients with renal cell carcinoma (RCC). We designed the present study to estimate the SPC incidence in Korean patients with RCC. MATERIALS AND METHODS: The study cohort was population-based and consisted of 40,347 individuals from the Korean Central Cancer Registry who were diagnosed with primary renal cancer between 1993 and 2013. Standardized incidence ratios (SIRs) for SPCs were estimated for different ages at diagnosis, latencies, diagnostic periods, and treatments. RESULTS: For patients with primary RCC, the risk of developing a SPC was higher than the risk of developing cancer in the general population (SIR, 1.13; 95% confidence interval, 1.08 to 1.18). Most cancer types showed higher incidences in patients with RCC than in the general population. However, the relative incidence of gastric cancer as an SPC varied by age. Gastric cancer incidence was elevated in young patients (< 30 years) with RCC, but reduced in older (≥ 30) patients with RCC. Patients with advanced RCC died prematurely, regardless of SPC development. In contrast, those with early-stage RCC survived for longer periods, although SPC development affected their post-RCC survival. After SPC development, women had better survival than men. CONCLUSION: In Korean patients with primary RCC, the incidence of SPC was 13% higher than the incidence of cancer in the general population. These findings may play important roles in the conduct of follow-up evaluations and education for patients with RCC.

PURPOSE: The purpose of this study is to compare the radiation therapy (RT) and radical prostatectomy (RP) of high-risk or locally advanced prostate cancer (PC) patients after neoadjuvant hormonal therapy (NHT). MATERIALS AND METHODS: This retrospective study evaluated patients underwent RT (42 patients) or RP (152 patients) after NHT at a single center during 2003–2014. Times to biochemical recurrence (BCR), pelvic local recurrence (PLR), metastasis, clinical painful symptom progression (CPSP), castration-resistant PC (CRPC), and overall survival were compared between the RT and RP groups, after adjustment for TN stage, using the Kaplan-Meier method and log-rank test. RESULTS: Significant inter-group differences were observed for age, Gleason score, initial PSA, and clinical and pathological T stages (all p 0.05). The independent predictor of CPSP was RP (hazard ratio, 0.291; p=0.013). CONCLUSIONS: Despite significantly different baseline parameters, RP provided better CPSP-free survival than RT among patients with localized high-risk or locally advanced PC.

PURPOSE: This study aimed to evaluate the prognostic significance of smoking status in muscle invasive bladder cancer (MIBC) and non-MIBC in recurrence-free (RFS), progression-free (PFS), disease-free survival (DFS), and cancer-specific survival (CSS). MATERIALS AND METHODS: We retrospectively evaluated 541 patients with MIBC and non-MIBC who were surgically treated during 2002–2013. Smoking status was defined as never smokers (NS; n=160, 30%), former smokers (FS; smoking cessation for ≥1 year, n=176, 33%), and current smokers (CS; >100 cigarettes, n=198, 37%). We statistically compared these groups' clinicopathological facCtors for the predictive factors for RFS and PFS for non-MIBC (NMIBC) and DFS for MIBC, and CSS using multivariate model. RESULTS: The CS, FS, and NS groups exhibited insignificantly different pathological staging, grades, and immunohistological characteristics (p>0.05). Among the 441 patients with NMIBC, pathologic tumor size was a significant risk factor for RFS (1–3 cm: hazard ratio [HR], 1.88; >3 cm: HR, 2.21; p < 0.05); age (HR, 1.06), intravesical therapy (HR, 0.25), and high-grade cancer (HR, 8.33) significant for PFS; and age (HR, 1.08), intravesical instillation (HR, 0.26), and smoking status (FS: HR, 0.40; CS: HR, 0.44) significant for CSS (p < 0.05). The 93 patients with MIBC had no significant risk factors for DFS, although their significant risk factors for CSS were age (HR, 1.05), female sex (HR, 2.64), and carcinoma in situ (HR, 4.72) (p < 0.05). CONCLUSIONS: Smoking status only significantly affected CSS in patients with NMIBC.

PURPOSE: This descriptive study assessed the current trends in the incidence of urological cancers and patient survival in Korea. MATERIALS AND METHODS: In this nationwide retrospective observational study based on the data from the Korea National Cancer Incidence Database (KNCIDB), this study analyzed the age-standardized incidence rates (ASRs) and annual percentage changes (APCs) of kidney, bladder, prostate, testicular, and penile cancers as well as cancer of the renal pelvis and ureter between 1999 and 2012. The relative survival rates (RSRs) were calculated for urological cancer patients diagnosed between 1993 and 2012 from the KNCIDB data. RESULTS: Prostate cancer was diagnosed in 66,812 individuals followed by bladder (41,549) and kidney (36,836) cancers. The overall ASR (18.26 per 100,000) increased with age because of the higher ASRs of bladder and prostate cancers in the elderly. The ASR for kidney cancer was highest in the 40-59-year-old group, whereas testicular cancer occurred most frequently before the age of 40. The incidence of most urological cancers increased (overall APC, 6.39%; p < 0.001), except for penile (APC, –2.01%; p=0.05) and bladder (APC, –0.40%; p=0.25) cancers. The overall survival increased steadily (5-year RSR, 66.4% in 1993-1995 vs. 84.2% in 2008-2012; p < 0.001), particularly for prostate (by 34.10%) and kidney (by 16.30%) cancers, but not for renal pelvis and ureter cancers (–7.20%). CONCLUSION: The most common urological cancer in Korea was prostate cancer followed by bladder and kidney cancers. The incidence of most urological cancers, except for penile and bladder cancers, increased. Survival also increased, particularly for prostate and kidney cancers.

One of the most significant risk factors for prostate cancer (PC) is a family history of the disease, with germ-line mutations in the breast cancer predisposition gene (BRCA) 2 conferring the highest risk. We here report a 56-year-old man presented with painful gait disturbance and diagnosed PC with multiple disseminated bone metastases. The patient had a strong family history of breast cancer with his 2 nieces affected. Furthermore, his aunts and uncles from both sides were diagnosed with stomach, ovarian, and colorectal cancers. His genomic sequencing analysis of the BRCA genes revealed the same BRCA2 deleterious mutation that his breast cancer-affected nieces carried. Previous studies have suggested that BRCA2-mutated PC is associated with a more aggressive phenotype and poor prognosis. Our experience in the present case also indicated the urgent needs for novel treatment modality and PC screening in this high-risk group of patients.

PURPOSE: The purpose of this study is to compare the outcomes of first-line systemic targeted therapy (TT) and immunotherapy (IT) in patients with metastatic renal cell carcinoma (mRCC). MATERIALS AND METHODS: This study was a retrospective review of the data of 262 patients treated with systemic IT or TT with tyrosine kinase inhibitors between 2003 and 2013. The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were assessed using Response Evaluation Criteria in Solid Tumor ver. 1.0 criteria and the Kaplan-Meier method with log-rank test. RESULTS: During the median 4.3-month treatment and the 24-month follow-up period, the ORR/PFS/OS of the overall first-line and second-line therapy were 41.9%/8.1 months/16.8 months and 27.5%/6.5 months/15.3 months, respectively. The first-line TT/IT/sequential IT had a PFS of 9.3/6.4/5.7 months and an OS of 15.8/16.5/40.6 months (all p < 0.05). The second-line of TT/IT had a PFS of 7.1/2.1 months (both p < 0.05) and an OS of 16.6/8.6 months (p=0.636), respectively. Pazopanib provided the best median PFS of 11.0 months (p < 0.001) and a quadruple IT regimen had a superior PFS (p=0.522). For OS, sequential treatment with IT and TT was superior compared to treatment with either IT or TT alone (40.6/16.5/15.8 months, p=0.014). The prognosis according to the Memorial Sloan Kettering Cancer Center model showed that favorable/intermediate/poor risk groups had a PFS of 8.5/10.4/2.3 months, and an OS of 43.1/20.4/5.6 months, respectively. The prognosis calculated using the Heng model showed that the favorable/intermediate/poor risk groups had a PFS of 9.2/3.9/2.7 months, and an OS of 32.4/16.5/6.1months, respectively (all p < 0.001). CONCLUSION: In patients with mRCC, TT provided a better PFS and OS compared with IT.

PURPOSE: The study was aimed to determine the correlations of tissue-based biomarker expressions between primary and metastatic specimens of renal cell carcinoma and with several well-known prognostic clinicopathological parameters. MATERIALS AND METHODS: The immunohistochemistry (IHC) was used to determine the expression levels of 9 tissue-based markers calculated in H-score expressed by percentage of expression multiplied by the intensity score (0, 1, 2, and 3 points). Using 17 patients' 38 specimens paired with primary renal lesion and its metastatic lesions collected between 2004 and 2015, Tissue microarray with IHC was performed with BAP1, PBRM1, pS6, PTEN, TGase2, PD-L1, CA9, PSMA, and Ki-67 on formalin-fixed paraffin-embedded sections. Pearson correlation and accuracy test were performed to analyze the correlation between primary and metastatic tissues. RESULTS: The 17 patients' mean age was 56.9 years old, mean tumor size was 7.9 cm, and the male to female ratio was 13:4 (76.5%:23.5%), respectively. Three patients had 2, 3, and 3 metastatic tissues, and the rest of 14 patients had only one metastatic tissue. The H-score (PSMA and Ki67) and intensity score (pS6 and PSMA) showed that some differential significant markers were identified which had statistical correlations of expression levels between primary and metastatic lesions among 9 markers. However, no real correlation of PSMA, Ki67, and pS6 markers were found their expressions of between primary and metastatic tissues because of their skewed expressions. CONCLUSIONS: Tissue markers failed to correlate their expression levels in primary lesions with those of metastatic lesions.
