Quantification of the individual risk of each Gleason pattern, including tertiary Gleason pattern 5, after radical prostatectomy: development of the modified Gleason grade grouping (mGGG) model. BMC Cancer 2020; 20:371. [PMID: 32357849 PMCID: PMC7195773 DOI: 10.1186/s12885-020-06880-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Accepted: 04/20/2020] [Indexed: 12/05/2022] Open
Abstract
Background While the new Gleason grade grouping (GGG), which started in 2016, has been widely validated in prostate cancer, it does not incorporate the concept of tertiary Gleason pattern 5. Furthermore, no study has “quantified” the individual risk of each Gleason pattern, including tertiary Gleason pattern 5, after radical prostatectomy. Methods We reviewed 1022 men with adjuvant-treatment-naïve prostate cancer who underwent radical prostatectomy between 2005 and 2017. The primary endpoint was biochemical recurrence-free survival, defined as two consecutive prostate-specific antigen measurements ≥0.2 ng/ml after surgery. The individual quantitative risk score (IQRS) of each amount (primary/secondary/tertiary) of each Gleason pattern (3/4/5) was calculated using the Cox regression model. On the basis of the IQRS, the modified Gleason grade grouping (mGGG) model was developed. As a robustness analysis of the mGGG model, salvage treatment-free survival was also assessed. Results During a median follow-up of 45 months, 229 of 1022 (22.4%) patients developed biochemical recurrence. The IQRS of each Gleason pattern was as follows: primary 5, 1.81 points (hazard ratio [HR] 6.13); secondary 5, 1.37 points (HR 3.92); tertiary 5, 0.87 points (HR 2.39); primary 4, 1.07 points (HR 2.91); secondary 4, 0.79 points (HR 2.21); and any Gleason pattern 3, 0 points (HR 1). Based on the IQRS, the mGGG model was developed, which classified patients into the following five groups: I (3 + 3 or less); II (3 + 4); III (4 + 3); IV (3 + 4 + t5, 4 + 3 + t5, 3 + 5, 5 + 3, and 4 + 4); V (4 + 4 + t5, 4 + 5, 5 + 4, and 5 + 5). The c-index for biochemical recurrence-free survival was significantly improved from 0.655 of the original GGG model to 0.672 of the mGGG model (P < 0.05). In the robustness analysis, the c-index for salvage treatment-free survival was also significantly improved from 0.619 of the original GGG model to 0.638 of the mGGG model (P < 0.05). Conclusions The quantitative risk of tertiary (< 5%) Gleason pattern 5 is slightly higher than that of secondary (5–50%) Gleason pattern 4. Our newly developed mGGG model more accurately predicts outcomes after radical prostatectomy than the original GGG model.

Abstract
Background Acute pyelonephritis (APN) with obstructive uropathy often causes sepsis. Recently, sepsis was redefined using the sequential organ failure assessment (SOFA) score, based on the new Sepsis-3 criteria. We investigated predictors for sepsis using this new definition in patients with obstructive APN associated with upper urinary tract calculi. Methods We retrospectively evaluated patients who were admitted to our hospital for treatment of obstructive APN associated with upper urinary tract calculi. Blood and urine samples were collected before treatment of obstructive APN. Treatment included adequate antimicrobial therapy and emergency drainage to decompress the renal collecting system. We diagnosed sepsis using the new Sepsis-3 definition. We assessed predictors for sepsis by multivariate logistic regression analysis. Results Sixty-one patients were included in this study. Overall, all patients underwent emergency drainage, and 11 (18.0%) patients showed sepsis. There were no significant differences in performance status or comorbidities between sepsis and non-sepsis groups. Platelet count and serum albumin level were significantly lower in the sepsis group than in the non-sepsis group (p = 0.001 and p = 0.016, respectively). Procalcitonin (PCT) and presepsin (PSEP) levels were significantly higher in the sepsis group than in the non-sepsis group (p < 0.001 and p < 0.001, respectively). Multivariate analysis showed that PCT elevation (OR = 13.12, p = 0.024) and PSEP elevation (OR = 13.13, p = 0.044) were independent predictors for sepsis. Conclusions Elevation of PCT and PSEP levels before treatment might predict the development of sepsis in patients with obstructive APN.

Abstract
AIMS BCOR gene alteration is a genetic signature of rare subsets of sarcomas. Most BCOR-associated sarcomas thus far reported are in the pediatric population, except for uterine sarcomas. We studied seven cases of BCOR-associated non-uterine sarcomas in adult patients. METHODS AND RESULTS The patients were four men and three women ranging from 26 to 71 years in age. Three tumors, two of which primarily affected the kidney, showed BCOR-CCNB3. One tumor with a ZC3H7B-BCOR occurred in the chest wall, and a tumor with a novel CIITA-BCOR was found in the sinonasal tract. Two tumors in the lung and breast harbored exon 15 internal tandem duplications of BCOR, a highly unexpected observation in this age group. All seven sarcomas consisted of dense proliferations of uniform round to spindle cells with fine chromatin within vascular stroma. BCOR-CCNB3 sarcomas showed swirling fascicular growth. The tumor with the ZC3H7B-BCOR fusion showed a multinodular growth of spindle cells, and the tumors with the CIITA-BCOR fusion showed palisading of oval cells. Both tumors with BCOR internal tandem duplication demonstrated nested to palisading growth of round cells within sclerotic non-myxoid stroma. All seven sarcomas diffusely expressed BCOR and SATB2 immunohistochemically, with all three BCOR-CCNB3 sarcomas being immunopositive for CCNB3. BCOR alterations were confirmed by RNA sequencing, polymerase chain reaction, Sanger sequencing, and/or fluorescence in situ hybridization. CONCLUSIONS This study expands the clinicopathologic and molecular spectrum of BCOR-associated sarcomas, and emphasizes the importance of being aware of this entity in the differential diagnosis of adult non-uterine sarcomas.

Abstract
OBJECTIVES To investigate intraocular pressure and visual function in patients with ocular diseases undergoing robot-assisted laparoscopic prostatectomy. METHODS We carried out a prospective clinical study of patients undergoing robot-assisted laparoscopic prostatectomy for localized prostate cancer at The University of Tokyo Hospital from December 2015 to March 2017. An ophthalmologist measured intraocular pressure, and carried out visual field testing at 0-2 months before and 7 days after robot-assisted laparoscopic prostatectomy. During the surgery, an anesthesiologist measured intraocular pressure at specified time points. RESULTS A total of 110 patients were enrolled and 98 eligible patients were analyzed; 37 were diagnosed with ocular diseases before robotic-assisted laparoscopic prostatectomy (17 with glaucoma, 20 with other ocular diseases). Intraocular pressure significantly increased during robot-assisted laparoscopic prostatectomy. Transient postoperative visual field defect was detected in 24 eyes of 17 patients, including six patients with ocular diseases at 7 days after surgery. At 3 months after surgery, one of 34 glaucomatous eyes and one of 40 eyes with non-glaucomatous ocular diseases continued to show visual field defect, although visual field defect in the remaining patients recovered to preoperative conditions within 3 months. CONCLUSIONS Our findings suggest that robot-assisted laparoscopic prostatectomy can be safely carried out in patients with ocular diseases, even those with glaucoma, after precautionary consultation with an ophthalmologist.

Abstract
Background Endothelial cells (ECs) make up the innermost layer throughout the entire vasculature. Their phenotypes and physiological functions are initially regulated by developmental signals and extracellular stimuli. The underlying molecular mechanisms responsible for the diverse phenotypes of ECs from different organs are not well understood. Results To characterize the transcriptomic and epigenomic landscape in the vascular system, we cataloged gene expression and active histone marks in nine types of human ECs (generating 148 genome-wide datasets) and carried out a comprehensive analysis with chromatin interaction data. We developed a robust procedure for comparative epigenome analysis that circumvents variations at the level of the individual and technical noise derived from sample preparation under various conditions. Through this approach, we identified 3765 EC-specific enhancers, some of which were associated with disease-associated genetic variations. We also identified various candidate marker genes for each EC type. We found that the nine EC types can be divided into two subgroups, corresponding to those with upper-body origins and lower-body origins, based on their epigenomic landscape. Epigenomic variations were highly correlated with gene expression patterns, but also provided unique information. Most of the deferentially expressed genes and enhancers were cooperatively enriched in more than one EC type, suggesting that the distinct combinations of multiple genes play key roles in the diverse phenotypes across EC types. Notably, many homeobox genes were differentially expressed across EC types, and their expression was correlated with the relative position of each organ in the body. This reflects the developmental origins of ECs and their roles in angiogenesis, vasculogenesis and wound healing. Conclusions This comprehensive analysis of epigenome characterization of EC types reveals diverse transcriptional regulation across human vascular systems. These datasets provide a valuable resource for understanding the vascular system and associated diseases.

Abstract
Purpose The aim of the present study was to evaluate the pathological and oncological outcomes of laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP) performed by one surgeon at a single center. Subjects We evaluated 700 patients with localized prostate cancer (i.e., 250 received LRP and 450 received RARP) in the study. The clinicopathological outcomes, positive surgical margin (PSM) frequency, and biochemical recurrence (BCR)–free survival were compared between LRP and RARP. Results At diagnosis, the median patient age and level of prostate-specific antigsen in the serum for LRP were 68 years and 8.1 ng/ml, respectively, while those for RARP were 66 years and 7.7 ng/ml, respectively. In the LRP group, the overall PSM rate was 31.2% (11.1% for pT2a, 19.0% for pT2b, 25.0% for pT2c, 60.0% for pT3a, 64.3% for pT3b, and 50% for pT4). In the RARP group, the overall PSM rate was 20.7% (4.8% for pT2a, 15.9% for pT2b, 12.9% for pT2c, 36.9% for pT3a, 46.2% for pT3b, and 100% for pT4). The PSM rate was significantly lower for RARP in men with pT2c, pT3a, or pT3b disease (p = 0.006, p = 0.009, and p = 0.027, respectively). Based on the multivariate analysis, RARP reduced the risk of BCR (hazard ratio = 0.8, p = 0.014). Conclusions We compared the pathological findings and rates of BCR-free survival between patients who received LRP and those who received RARP at a single center. The rate of BCR-free survival was significantly higher in men classified as D'Amico high-risk patients who received RARP versus that reported in D'Amico high-risk patients who received LRP.

Abstract
We carried out structure-activity relationship study on anti-cancer effects of naftopidil (1) and its metabolites, resulted in identification of 1-(4-hydroxy-2-methoxyphenyl)piperazin-1-yl)-3-(naphthalen-1-yloxy) propan-2-ol (2, HUHS190), a major human metabolite of 1, which exhibited the most selective toxicities between against normal and cancer cells (Table 1). 2 was more hydrophilic compared to 1, was enough to be prepared in high concentration solution of more than 100 μM in saline for an intravesical instillation drug. Moreover, serum concentration of 2 was comparable to that of 1, an oral preparation drug, after oral administration at 32 mg/kg (Fig. 3). Both of 1 and 2 showed broad-spectrum anti-cancer activities in vitro, for example, 1 and 2 showed inhibitory activity IC50 = 21.1 μM and 17.2 μM for DU145, human prostate cancer cells, respectively, and IC50 = 18.5 μM and 10.5 μM for T24 cells, human bladder cancer cells. In this study, we estimated anticancer effects of 2 in a bladder cancer model after intravesical administration similar to clinical cases. A single intravesical administration of 2 exhibited the most potent inhibitory activities among the clinical drugs for bladder cancers, BCG and Pirarubicin, without obvious side effects and toxicity (Fig. 4). Thus, HUHS190 (2) can be effective for patients after post-TURBT therapy of bladder cancer without side effects, unlike the currently available clinical drugs.

Abstract
Oncolytic virus therapy is a promising new option for cancer. It utilizes genetically engineered or naturally occurring viruses that selectively replicate in and kill cancer cells without harming normal cells. T-VEC (talimogene laherparepvec), a second-generation oncolytic herpes simplex virus type 1, was approved by the US Food and Drug Administration for the treatment of inoperable melanoma in 2015 and subsequently approved in Europe in 2016. Other oncolytic viruses using different parental viruses have also been tested in Phase III clinical trials and are ready for drug approval: Pexa-Vec (pexastimogene devacirepvec), an oncolytic vaccinia virus, CG0070, an oncolytic adenovirus, and REOLYSIN (pelareorep), an oncolytic reovirus. In Japan, as of May 2018, several oncolytic viruses have been developed, and some have already proceeded to clinical trials. In this review, we summarize clinical trials assessing oncolytic virus therapy that were conducted or are currently ongoing in Japan, specifically, T-VEC, the abovementioned oncolytic herpes simplex virus type 1, G47Δ, a third-generation oncolytic herpes simplex virus type 1, HF10, a naturally attenuated oncolytic herpes simplex virus type 1, Telomelysin, an oncolytic adenovirus, Surv.m-CRA, another oncolytic adenovirus, and Sendai virus particle. In the near future, oncolytic virus therapy may become an important and major treatment option for cancer in Japan.

Abstract
Introduction Since pheochromocytomas present with various complications due to catecholamine hypersecretion, their perioperative management needs special attention. Case presentation A 45‐year‐old man visited our hospital with a complaint of abdominal swelling. Radiological and endocrinological assessments determined the tumor as a giant (>20 cm) cystic pheochromocytoma. After administration of doxazosin, the patient underwent radical surgery. Since the tumor was extremely large and fixed to surrounding structures, we punctured it and aspirated cystic fluid to improve the tumor's mobility. However, during the aspiration, the patient developed acute hypotension, which could be reversed by suction withdrawal and vasopressor administration. A similar event occurred during a second aspiration. Eventually, the tumor was successfully excised with negative surgical margin. The cystic fluid proved to contain extremely high concentrations of catecholamines, which might result in the hypotension. Conclusion We report the first case who developed acute hypotension due to aspiration of cystic fluid from giant pheochromocytoma.

Abstract
Stabilisation of fragile oligonucleotides, typically small interfering RNA (siRNA), is one of the most critical issues for oligonucleotide therapeutics. Many previous studies encapsulated oligonucleotides into ~100-nm nanoparticles. However, such nanoparticles inevitably accumulate in liver and spleen. Further, some intractable cancers, e.g., tumours in pancreas and brain, have inherent barrier characteristics preventing the penetration of such nanoparticles into tumour microenvironments. Herein, we report an alternative approach to cancer-targeted oligonucleotide delivery using a Y-shaped block catiomer (YBC) with precisely regulated chain length. Notably, the number of positive charges in YBC is adjusted to match that of negative charges in each oligonucleotide strand (i.e., 20). The YBC rendezvouses with a single oligonucleotide in the bloodstream to generate a dynamic ion-pair, termed unit polyion complex (uPIC). Owing to both significant longevity in the bloodstream and appreciably small size (~18 nm), the uPIC efficiently delivers oligonucleotides into pancreatic tumour and brain tumour models, exerting significant antitumour activity.

Abstract
AIMS To clarify longitudinal change of lower urinary tract symptoms (LUTS) and various types of urinary incontinence following robot-assisted radical prostatectomy (RARP) using validated questionnaires. MATERIALS AND METHODS The core lower urinary tract symptom score (CLSS) and the International Consultation on Incontinence Questionnaire (ICIQ)-Short Form (SF) questionnaires were administered to 607 consecutive, treatment-naïve men receiving RARP before and after surgery. The time course of comprehensive LUTS and various types of urinary incontinence, including stress-, urgency-, and urinary incontinence with no obvious reason, were evaluated. Continence recovery rates were compared for the different types of incontinence using Cox hazard regression analysis. RESULTS After surgery, stress urinary incontinence (SUI) was reported most frequently (32% of cases) as the chief complaint with the most impact on daily life, as assessed by the CLSS questionnaire, followed by urgency urinary incontinence (UUI; 27% of cases). The rates of continence recovery differed among the different types of urinary incontinence, such as after urinating, when dressed, when asleep, when physically active or exercising, when coughing or sneezing, before reaching the toilet, and for no obvious reason. Incontinence for no obvious reason at 1 month after RARP was a strongest prognostic factor of delayed continence recovery (hazard ratio, 0.61; P < 0.0001), whereas patients reporting SUI and UUI gradually regained continence. CONCLUSIONS Further time course on continent recovery after RARP would be more precisely predictable based on the incontinence status at one month postoperatively. Especially, incontinence with no obvious reason would be a significant factor for delayed recovery.

Abstract
BACKGROUND Evidence regarding volume-outcome effects on peritoneal dialysis (PD) catheter implantation is limited. This study aimed to investigate associations between hospital volume (annual caseload of catheter implantation) and perioperative outcomes. METHODS Clinical data for patients who underwent PD catheter implantation from 2007 to 2012 were extracted from the Japanese nationwide Diagnosis Procedure Combination database. Hospital volume was divided into tertiles: low-volume (1 - 6 cases/year), medium-volume (7 - 13 cases/year), and high-volume (≥ 14 cases/year). Multivariate logistic regression analysis for the occurrence of any adverse events and blood transfusion, and gamma-distributed log-linked linear regression analysis for postoperative length of stay were conducted with explanatory variables of hospital volume, age, sex, Charlson comorbidity index, history of hemodialysis, type of anesthesia, and type of hospital. RESULTS Among 906, 855, and 744 cases in the low-volume, medium-volume, and high-volume groups, overall adverse events were 10.0%, 7.6%, and 6.0%, transfusion rates were 1.3%, 1.1%, and 0.9%, and median postoperative stays were 12, 10, and 9 days, respectively. In multivariate analyses, compared with the low-volume group, medium-volume and high-volume groups were associated with a lower incidence of overall adverse events (odds ratio [OR] = 0.71, p = 0.058, and OR = 0.59, p = 0.013, respectively) and shorter postoperative stay (% difference = -10.5%, p = 0.023, and % difference = -18.5%, p = 0.001, respectively), while no significant association was detected for transfusion. CONCLUSIONS Less frequent adverse events and shorter stays were observed in higher-volume centers. Inverse volume-outcome relationships in PD catheter implantation were confirmed.

Abstract
Collecting (Bellini) duct carcinoma of the kidney is a rare lethal tumor, and its prognostic factors remain unclear. The present study investigated the prognostic significance of neutrophil-to-lymphocyte ratio, which has recently been recognized as a readily available prognostic marker in various malignancies, in patients with collecting duct carcinoma. Of 11 patients who were pathologically diagnosed with collecting duct carcinoma at our institution, nine died of collecting duct carcinoma, one died of a postoperative complication, and one was alive, with a median follow-up period of 6 (range: 0-97) months. Both univariate and multivariate analyses associated neutrophil-to-lymphocyte ratio ≥4 (median) with worse cancer-specific survival. Notably, the sole surviving patient maintained a low neutrophil-to-lymphocyte ratio (<4) both at the initial diagnosis and at the time of distant recurrence. These results suggest that neutrophil-to-lymphocyte ratio might serve as a useful biomarker for collecting duct carcinoma as well as other malignancies.

Abstract
The clinical significance of random bladder biopsies in primary non-muscle-invasive bladder cancer is unclear. The present study investigated the significance of positive random bladder biopsies in primary T1 NMIBC. The present study retrospectively reviewed the records of 71 patients with primary pT1N0M0 bladder cancer who underwent transurethral resection of the bladder tumor (TURBT) and concomitant random bladder biopsy. A total of 12 patients who received cystectomy immediately following the TURBT were excluded, and the remaining 59 patients were included in the analysis. Random bladder biopsy was defined as a cold-cup biopsy of pre-specified normal-looking areas in the bladder. The association of clinicopathological factors, including random biopsy results, with intravesical recurrence were assessed by univariate and multivariate Cox proportional hazards analyses. Of the 59 patients, 15 (25%) demonstrated carcinoma in situ (CIS) lesions on random bladder biopsy: Five (33%) in biopsy specimens alone and the remaining 10 (67%) in biopsy and TUR specimens. Positive random biopsy was associated with preoperative positive urine cytology (P=0.011) and small size of the main tumor (P=0.008). Multivariate analysis demonstrated positive random biopsy as the sole independent poor prognostic factor for intravesical recurrence (hazard ratio: 4.69, P=0.014). The five patients who had CIS detected in biopsy specimens alone had worse, although non-significantly worse, recurrence-free survival compared with those with CIS detected in biopsy and TUR specimens (P=0.100). In conclusion, positive bladder random biopsy, equivalent to the presence of CIS, was an independent predictor of recurrence in primary T1 bladder cancer. Given that one-third of CIS lesions could not have been detected without biopsy, random bladder biopsy should be considered for patients with T1 tumors.

Abstract
56 Background: There are few reports of the health-related quality of life (HRQOL) of Asian prostate cancer patients who choice active surveillance. We evaluate HRQOL in participants of the Prostate Cancer Research International Active Surveillance study (PRIAS-JAPAN). Methods: The participants’ general HRQOL was assessed longitudinally using the Short Form 8 Health Survey (SF-8) at enrollment and annually thereafter until discontinuation of active surveillance (AS). We compared the quality of life and baseline score of participants with that of the general population (Norm-based scoring [NBS] 50) using paired t-test and the mixed models. Age-adjusted logistic regression was applied to the 3-year AS remaining rate. Results: The SF-8 questionnaire was administered to 570 patients (median age, 68 [range, 45–87] years). We evaluated 484, 328, 140, 84, and 68 patients at enrollment and 1, 2, 3, and 4 years thereafter. At enrollment, the mean physical component summary (PCS) score and all subscales revealed better HRQOL than NBS. No significant difference was noted in mental component summary (MCS) compared to NBS at enrollment. However, MCS at 1, 2, and 4 years was higher than the NBS. PCS slightly diminished in 4 years, whereas MCS at all time points showed no change. Age-adjusted logistic regression showed an OR of 1.66 (95% CI: 1.047–2.632, P = 0.0313) on 3-year AS remaining rate in favor of patients with above median MCS at enrollment. Conclusions: Men who were enrolled into the PRIAS-JAPAN study had better HRQOL than that of NBS. PCS decreased but MCS did not. The AS remaining rate was influenced by baseline MCS.

Abstract
BACKGROUND Although cases of multiple primary malignant neoplasms are increasing, reports of more than three or four primary metachronous malignant neoplasms are extremely rare. Moreover, very few publications have provided a genetic mutational analysis or have evaluated risk factors associated with such neoplasms. We present an extremely rare case of nine primary malignant lesions in a man who was successfully treated. We also report on microsatellite stability status, analyze risk factors, and discuss the relevant literature. CASE PRESENTATION Between 67 and 73 years of age, a male patient developed nine primary metachronous malignant lesions: Three were located in the esophagus, two in the stomach, two in the colorectum, one in the prostate gland, and one in the external ear canal. The patient's clinical history included hypertension, atrial fibrillation, an acoustic schwannoma, and heavy smoking. The lesions were diagnosed during regular screening over a six-year period. He was successfully treated with surgery (both open surgical and endoscopic resection of lesions) and adjuvant chemotherapy. Immunohistochemistry and mutational analysis showed that the lesions were microsatellite stable, and the KRAS, BRAF, p53, and nuclear β-catenin status was not uniform among the lesions. CONCLUSIONS Given that the presence of more than three or four neoplasms is extremely rare, the present case of nine primary malignancies with no associated microsatellite instability and no apparent predisposing hereditary conditions, is extraordinary. Our case study shows that it is possible for up to nine sporadic neoplasms to occur, and efficient disease management requires diligent screening and early detection.

Abstract
AIM To investigate the feasibility of chemokines and cytokines potentially elevated in the bladder tissue of Hunner type interstitial cystitis (HIC) as urinary markers for distinguishing HIC from non-Hunner type interstitial cystitis (NHIC) METHODS: Urine specimens were collected from 41 HIC patients, 25 NHIC patients, and 31 healthy volunteers (control). The supernatants of urine specimens were subjected to ELISA kits for measurements of 10 cytokines and chemokines, whose gene expression was known to be elevated in HIC bladder tissue. Urinary levels normalized by urinary creatinine (Cr) concentration were compared among three groups. Efficiency in differentiating IC and IC subtypes was explored by ROC analysis. The correlation of marker levels with symptom severity, assessed by O'Leary-Sant's symptom index (OSSI) and problem index (OSPI), was examined. RESULTS The urinary levels of CXCL10 and NGF were significantly higher in HIC than NHIC. CXCL10 and NGF differentiated HIC against NHIC with AUC of 0.78 and 0.68, respectively. Combination of CXCL10 and NGF levels yielded an AUS of 0.81. The CXCL10 cut-off of 53.2 pg/mg Cr had sensitivity of 46.1%, specificity of 93.7%, positive predictive value of 97.7%, and negative predictive value of 60.0%. The urinary level of other cytokines showed no significant difference between HIC and NHIC. Significant correlation with symptoms was detected for CXCL10 alone. CONCLUSION The results suggested that increased urinary level of CXCL10 combined with or without high NGF level could be a promising supplementary biomarker for differentiating HIC from NHIC with modest sensitivity and high specificity.
