RESUMEN
Small cell carcinoma (SCC) of the urinary bladder is a rare and highly aggressive subtype of bladder cancer. Most cases are diagnosed at advanced stages, and its therapeutic strategy remains unestablished. Here, we report a case of bladder SCC in which multidisciplinary treatment has resulted in relatively long-term survival. A 68-year-old man presented with gross hematuria. A cystoscopy revealed an invasive bladder tumor. A transurethral resection of bladder tumor (TURBT) was performed, and the pathological diagnosis was SCC. After systemic chemotherapy using etoposide and carboplatin and subsequent TURBT, a radical cystectomy and ileal conduit were performed. Three months postoperatively, the patient had a recurrence in the para-aortic lymph node. Systemic combination chemotherapy with carboplatin plus irinotecan (CBDCA + CPT-11) was administered, followed by amrubicin and an immune checkpoint inhibitor. In addition to this treatment, radiation therapy for the metastatic region led to the reduction of pain and shrinkage of the metastatic lesion. The patient survived for 2 years after the initial diagnosis. Our report indicates that multidisciplinary treatment can be effective for SCC of the bladder, and a therapeutic strategy including the identification of novel biomarkers should be established.
RESUMEN
Here, we report a rare case of bladder cancer within the left congenital periureteral diverticulum, termed the Hutch's diverticulum. Following transurethral resection of the bladder tumor, repeated pyelonephritis was caused by stricture of the diverticulum orifice and ureter. We attempted transurethral dilation and ureteral stenting, but the obstruction did not improve. The patient's renal dysfunction showed gradual progression due to recurrent left pyelonephritis as well as the ureteral obstruction. Therefore, we finally performed a partial cystectomy, involving stricture and ureteral reimplantation. No tumor recurrence was observed over 39 months, and renal dysfunction did not progress following partial cystectomy.
RESUMEN
We report a rare case of peritoneal and pulmonary tuberculosis after intravesical instillation of Bacillus Calmette-Guérin (BCG). A 76-year-old man diagnosed as high-grade urothelial carcinoma (UC) with carcinoma in situ (CIS) was treated with intravesical BCG instillation and transurethral resection of bladder tumor (TUR-BT). Three months later, TUR-BT for recurrent tumors and multiple site biopsy of bladder mucosa were performed. During TUR-BT, near perforation in the posterior wall was observed, and was disappeared after observation with urethral catheterization for 1 week. Two weeks later, he was admitted with a complaint of abdominal distention, and a computed tomography (CT) showed ascites. One week later, CT showed pleural effusion and worsening of ascites. Drainage of pleural effusion and ascites puncture was performed, and elevated adenosine deaminase (ADA) and lymphocytes count were subsequently found. In laparoscopic examination, numerous white nodules were observed in the peritoneum and omentum, and Langhans giant cells were pathologically identified in biopsy specimens. Mycobacterium culture confirmed Mycobacterium tuberculosis complex. The patient was then diagnosed with pulmonary and peritoneal tuberculosis. Anti-tuberculous agents consisting of isoniazid (INH), rifampicin (RFP), and ethambutol (EB) were administered. Six months later, a CT scan showed no evidence of pleural effusion or ascites. There has been no recurrence of either urothelial cancer or tuberculosis during follow-up for 2 years.
RESUMEN
The objective of this study was to characterize time-dependent recovery of erectile function in Japanese patients following robot-assisted radical prostatectomy (RARP) using the erection hardness score (EHS). This study prospectively included 170 Japanese patients with localized prostate cancer (PC) undergoing RARP without neoadjuvant hormonal therapy. The erectile function of each patient was assessed based on the International Index of Erectile Function-5 (IIEF-5) and EHS at the baseline and on every visit to an outpatient clinic after RARP. In this series, potency was defined as the ability to have an erection sufficient for intercourse, corresponding to EHS ≥3, while patients with EHS ≥2 were regarded as those with erectile function. Of these 170 patients, 20 and 75 underwent bilateral and unilateral nerve-sparing procedures, respectively; however, non-nerve-sparing procedures were performed in the remaining 75. A proportional increase in the IIEF-5 score according to EHS was noted at 24 months after RARP. At 6, 12 and 24 months after RARP, the recovery rates of erectile function were 11.9, 21.7 and 35.8 %, respectively, while those of potency were 3.8, 9.8 and 13.7 %, respectively. Of several factors examined, the age, preoperative IIEF-5 score and nerve-sparing procedure were identified as independent predictors of erectile function recovery. These findings suggest that favorable erectile function recovery could not be achieved in Japanese PC patients even after the introduction of RARP; therefore, it might be preferable for such a cohort to use EHS rather than IIEF-5 as an assessment tool for the postoperative recovery of erectile function.

OBJECTIVE: To evaluate the prognostic significance of the neutrophil-to-lymphocyte ratio in patients receiving chemotherapy with docetaxel for castration-resistant prostate cancer. METHODS: A total of 57 castration-resistant prostate cancer patients treated between 2009 and 2014 were included in the present retrospective study. All patient data, including clinicopathological factors, were assessed. Univariate and multivariate Cox regression models were used to predict overall survival and progression-free survival after chemotherapy initiation. RESULTS: The median overall survival and progression-free survival were determined as 19.0 months (range 1-61 months) and 10.0 months (range 1-56 months), respectively. The cut-off level of the neutrophil-to-lymphocyte ratio was set as the median value of 3.5 among all patients in this study. In Kaplan-Meier analysis, the median overall survival and progression-free survival were shorter in patients with a high neutrophil-to-lymphocyte ratio compared with those with a low neutrophil-to-lymphocyte ratio (15 vs 20 months, P = 0.0125; and 9.5 vs 15 months, P = 0.0132, respectively). The overall survival and progression-free survival periods in patients with a high neutrophil-to-lymphocyte ratio were significantly shorter than those of patients with a low neutrophil-to-lymphocyte ratio (P = 0.0178 and 0.0176, respectively). In the multivariate analysis, a high neutrophil-to-lymphocyte ratio was an independent predictor of overall survival and progression-free survival (hazard ratio 2.728, 95% confidence interval 1.05-7.09, P = 0.039; and hazard ratio 2.376, 95% confidence interval 1.12-5.06, P=0.024, respectively). CONCLUSION: The present study results suggest that the neutrophil-to-lymphocyte ratio is a useful prognostic factor in patients with castration-resistant prostate cancer treated by docetaxel chemotherapy. These findings might be useful in determining treatment strategies in the future.

OBJECTIVES: To evaluate the influence of prior abdominal surgery on surgical outcomes of robot-assisted radical prostatectomy in an early single center experience in Japan. METHODS: We reviewed medical records of patients with localized prostate cancer who underwent robot-assisted radical prostatectomy from October 2010 to September 2013 at Tottori University Faculty of Medicine, Yonago, Tottori, Japan. Patients with prior abdominal surgery were compared with those with no prior surgery with respect to total operative time, port-insertion time, console time, positive surgical margin and perioperative complication rate. Furthermore, the number of patients requiring minimal adhesion lysis was compared between the two groups. RESULTS: Of 150 patients who underwent robot-assisted radical prostatectomy, 94 (63%) had no prior abdominal surgery, whereas 56 patients (37%) did. The mean total operative time was 329 and 333 min (P = 0.340), mean port insertion time was 40 and 34.5 min (P = 0.003), mean console time was 255 and 238 min (P = 0.145), a positive surgical margin was observed in 17.9% and 17.0% patients (P = 0.896), and the incidence of perioperative complications was 25% and 23.4% (P = 0.825), respectively, in those with and without prior abdominal surgery. In the prior abdominal surgery group, 48 patients (80.4%) required adhesion lysis at the time of trocar placement or while operating the robotic console. CONCLUSION: Robot-assisted radical prostatectomy appears to be a safe approach for patients with prior abdominal surgery without increasing total operative time, robotic console time, positive surgical margin or the incidence of perioperative complications.

OBJECTIVE: To evaluate the impact of anatomical dimensions as measured using preoperative magnetic resonance imaging on the outcomes of robot-assisted laparoscopic prostatectomy. METHODS: We retrospectively reviewed 100 consecutive robot-assisted laparoscopic prostatectomy procedures that were carried out by a single surgeon at the Division of Urology, Department of Surgery, Tottori University Faculty of Medicine, Yonago, Japan. Preoperative clinical data and anatomical measurements, including the calculated prostate volume pelvic cavity index, were determined based on preoperative magnetic resonance imaging, and their effects on console time, estimated blood loss and surgical margin status were compared. RESULTS: Body mass index, the prostate anteroposterior diameter, and the prostate volume-to-pelvic cavity index ratio were all significantly correlated with console time and estimated blood loss, based on a univariate analysis (P < 0.05). The prostate craniocaudal diameter, prostate transverse diameter and prostate volume also correlated with console time. However, based on the multiple linear regression analysis, only the prostate volume-to-pelvic cavity index ratio was found to be a significant predictor of console time and estimated blood loss. Furthermore, when the 100 total cases were divided into 50 early cases and 50 late cases, the prostate volume-to-pelvic cavity index ratio correlated with console time and estimated blood loss only in the early group, and not in the late group. In contrast, anatomical measurements had no significant effect on surgical margin status. CONCLUSION: Magnetic resonance imaging can be a valuable adjunct to robot-assisted laparoscopic prostatectomy. Our data show that patients with larger prostates and narrow, deep pelvises might present more difficulty in robot-assisted laparoscopic prostatectomy procedures. However, the present data also show that this problem can be overcome by an experienced operator with improved surgical techniques.

BACKGROUND: The efficacy of adding target prostate biopsy (PBx) of suspected cancer lesions identified on magnetic resonance imaging (MRI) and/or transrectal ultrasonography (TRUS) to initial systematic PBx was evaluated. Moreover, the outcomes were compared between 2 physicians. METHODS: We retrospectively investigated 238 patients who underwent first-time PBx in our hospital. All patients were examined with prostate MRI before PBx. Fourteen systematic biopsies were obtained in all patients. When a suspected lesion was present on MRI and/or TRUS, the lesion was the target of target PBx. RESULTS: The overall detection rate of prostate cancer (PCa) was 45% (106/238). With target PBx, the PCa detection rate was 32% overall, while that of suspected lesions seen only on MRI was 32%, that of suspected lesions seen only on TRUS was 8% and that of suspected lesions seen on both MRI and TRUS was 52%. The same tendency was shown for each physician. Comparing systematic PBx and target PBx, the overall rate of Gleason score (GS) upgrading with target PBx was 13%. The rate of PCa detected only by systematic PBx was 95%. There was no significant difference between the 2 physicians. CONCLUSION: In initial PBx, the addition of target PBx of suspected cancer lesions detected by MRI and/or TRUS to systematic PBx might not be useful to improve the cancer detection rate. However, it may enable more accurate risk classification and detection of minute cancers with a high GS.
RESUMEN
OBJECTIVE: We evaluated the improvement of hydronephrosis longitudinally after laparoscopic dismembered Anderson-Hynes pyeloplasty in adult patients with ureteropelvic junction obstruction. MATERIAL AND METHODS: Sixteen patients underwent laparoscopic pyeloplasty at our institution between January 2006 and June 2012. Hydronephrosis was assessed by ultrasound and intravenous pyelography at 3, 6, 12, 18, and 24 months after pyeloplasty. RESULTS: The mean follow-up time was 24 months. Preoperative hydronephrosis was diagnosed as grade 2 and grade 3 in 8 patients each. Postoperative improvement of the hydronephrosis by one grade was observed in 56%, 73%, 67%, 50%, and 40% of patients at 3, 6, 12, 18, and 24 months, respectively. Improvement of the hydronephrosis by two grades was observed in 6%, 27%, 33%, 50%, and 60% of patients at 3, 6, 12, 18, and 24 months, respectively. In 5 of 12 patients (42%), hydronephrosis was still improving even after 12 months postoperatively. CONCLUSIONS: Adult patients demonstrate relatively rapid improvements in the degree of hydronephrosis after laparoscopic pyeloplasty and continue to improve for a long time.
RESUMEN
PURPOSE: To investigate the association between apical margin positivity and preoperative magnetic resonance imaging (MRI) in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RARP). PATIENTS AND METHODS: From September 2010 through November 2012, we treated 84 Japanese men with clinically localized prostate cancer with RARP. The excised specimens, which were divided into right and left fragments, were evaluated for the presence of positive surgical margins (PSMs) and preoperative MRI findings. RESULTS: The overall PSM rate was 21.4% (18 of 84 patients), 83.3% (15 of 18 cases) of which were situated in the apex. Evaluating the prostate divided into right and left fragments, the PSM rate was 10.7% at the apex (18 of 168 fragments). Cancer was suspected via preoperative MRI in 39 fragments (23.2%) and detected in the prostatic apex by prostate biopsy in 67 fragments (39.9%). Multiple regression analysis revealed that MRI and nerve-sparing procedures significantly indicate apical margin positivity (p = 0.005). CONCLUSIONS: The prostatic apex is the most common location of PSMs after RARP. Our results demonstrate that preoperative MRI for cancer of the prostatic apex may provide substantial information and enable complete cancer clearance.

OBJECTIVES: The present study investigated prognostic indicators, including clinicopathological and preoperative hematological factors, and developed a prognostic factor-based risk stratification model in bladder cancer patients treated with radical cystectomy. METHODS: Data were collected from 249 consecutive bladder cancer patients treated with radical cystectomy without neoadjuvant therapy. Prognostic values of the preoperative hematological parameters, along with the patients' clinicopathological parameters were evaluated. A risk stratification model was developed to predict disease-specific survival after radical cystectomy using the regression coefficients of multivariate analysis. RESULTS: In the multivariate analysis, preoperative hemoglobin and C-reactive protein levels, as well as the pathological factors of T stage, positive surgical margin and lymph node metastasis, were independently predictive of disease-specific survival. Low hemoglobin (<10.5 g/dL), a high C-reactive protein (>0.5 mg/dL), extravesical T stage (≥pT3a) and positive surgical margin were independent predictors of poor disease-specific survival. The risk stratification model showed significant differences in disease-specific survival between the three subgroups. CONCLUSIONS: This is the first report to show the significance of combining preoperative hemoglobin with the pathology of radical cystectomy specimens as an independent predictor for disease-specific survival, and it also represents the largest contemporary series to date demonstrating that two types of preoperative hematological disorders, assessed by hemoglobin and C-reactive protein, are independent predictors in bladder cancer patients treated with radical cystectomy. Our risk stratification model could provide physicians with useful prognostic information for identifying patients who might be candidates for multimodal treatments.

BACKGROUND: Although a very small number of Japanese hospitals had been performing robotic surgery before 2011, the number now using it is increasing rapidly due to the application of health insurance to robotic surgery for prostate cancer (PCa) since April, 2012. We report our initial experience of treating 100 patients by robot-assisted radical prostatectomy (RARP) with a focus on constitutional introduction and implementation based on minimal invasive surgery center (MISC) and patient outcomes. METHODS: The MISC involved all of the hospital sections related to robotic surgery including four surgery departments, anesthesiology, operating room nurses, medical engineers. The data were prospectively collected from the first 100 consecutive patients who underwent RARP under supervision of MISC for localized PCa from October 2010 to December 2012. RESULTS: During the period of our initial 100 cases of RARP, the gynecology, respiratory and digestive surgery departments performed initial cases of 20, 33 and 23 robotic surgeries under control of MISC. Peri-operative complications in RARP appeared to be minimal with no cases of intra-operative open conversion. The positive surgical margin rate was 19% for the entire series. At the median follow-up time of 11.9 months, 91% of patients had undetectable PSA levels, and 76% of patients were not using pads. Sequential urinary functional data indicated a significant beneficial effect on lower urinary tract symptoms beyond cancer control over a period of several months. Although the pre-operative potent patient number was small, the transitions of constant potency recovery at precise time points were shown according to different nerve sparing procedures. CONCLUSIONS: This is the first report of an initial 100 RARP cases that were implemented using the constitutional framework of an academic institution. The MISC is providing immeasurable benefits from the aspects of patient safety and education for the robotic surgical team. RARP is a safe and efficient method for achieving PCa control together with functional preservation, even during the initial trial for this procedure.

We analyzed whether three-dimensional vision, practice or previous laparoscopic experience improves the surgical performance of the bedside assistant during robot-assisted surgery. Six experienced laparoscopic surgeons and 15 novices carried out three skills drills imitating an assistant's maneuvers in robot-assisted surgery, and times for completing the tasks were recorded. Both the novice and experienced groups showed significantly shorter manipulation times for each drill with three-dimensional vision compared with two-dimensional or glassless three-dimensional vision. The experienced group showed significantly shorter manipulation times than the novice group for all types of vision. A significant improvement was observed 14 out of 18 times in the novice group, but only one out of 18 times in the experienced group. We can conclude that the use of three-dimensional visualization facilitates the performance of the assistant surgeon, especially if a novice, during robot-assisted surgery. Laparoscopic experience also improves the performance, whereas training is beneficial for novice assistant surgeons before carrying out actual operations.

INTRODUCTION: To date, only few studies focusing on the issue of host general and immune activity have been performed in localized prostate cancer (PCa). The aim of this study was to elucidate potent non tumor-related biomarkers that express aggressiveness of PCa treated by radical prostatectomy (RP). MATERIALS AND METHODS: Data from 179 patients who underwent RP were analyzed. The correlations between various kinds of non tumor-related factors in addition to tumor-related factors and biochemical recurrence (BCR) were analyzed. The correlations between pre-, intra- and post-operative factors were also analyzed. RESULTS: Thirty-two cases (17.9%) had a BCR. The factors found to be significantly predictive of BCR using a Cox-proportional hazard model were the pre-operative serum prostate specific antigen (PSA) level and the existence of pathological lymph node metastasis (LNM). A low pre-operative serum albumin level (<4.0 g/dl) was significantly correlated with BCR univariately. Logistic regression analysis revealed that a low pre-operative serum albumin level, an American Society of Anesthesiologists (ASA) score above class 2, and a Gleason score above 8 in the biopsy specimens were significantly predictive of pathological LNM. CONCLUSIONS: Tumor-related characteristics are more important for predicting BCR. However, our results suggest that low pre-operative serum albumin level may indicate extensive disease of clinically localized PCa and may ultimately be correlated with BCR. Although multiple reasons may account for the significance of the serum albumin level, it is noteworthy that delayed diagnostic and therapeutic procedures in comorbid patients with low serum albumin levels may lead to PCa progression.
RESUMEN
OBJECTIVES: Despite the surgical curability of renal cell carcinoma (RCC) and upper urinary tract urothelial carcinoma (UUT-UC), post-nephrectomy chronic kidney disease (CKD) continues to be a cause of concern. We investigated the correlation between the expression of apoptotic regulatory molecules in the nephrectomized, noncancerous cortex, as well as CKD progression and CKD-related mortality. MATERIALS AND METHODS: Fas and Bcl-2 mRNA and protein expression in surgically resected specimens from 100 patients with RCC and UUT-UC were determined. The estimated glomerular filtration rates (eGFR) were determined sequentially before surgery and up to 5 years after surgery. The relationships between CKD progression, the expression of these molecules in the renal cortex, and the clinical characteristics were analyzed. RESULTS: The mean 1-year postoperative percent eGFR decrease was 30.2 (Standard deviation [SD]: 15.2). The 1-year postoperative percent eGFR decrease greater than the approximate value of mean ± SD (45) was categorized as severe renal functional deterioration (SRFD). Glomerular Fas protein expression and a Fas/ß-actin mRNA ratio >0.3 were independent predictors for SRFD. Significantly increased mortality rates due to cardiovascular events were indicated by glomerular Fas protein expression, Fas mRNA levels >0.3, and SRFD. No significant change in Bcl-2 levels was observed. CONCLUSIONS: This study is the first report to demonstrate the significance of Fas expression in the nephrectomized normal cortex as a predictor of post-nephrectomy CKD progression. The results from nephrectomized kidney showed that the natural course of renal function in the remaining kidney may be affected not only by Fas-induced glomerular cell apoptosis but also by the total amount of Fas mRNA in cortical cells.

OBJECTIVES: To investigate mortality rates and to comprehensively analyze prognostic indicators after radical nephrectomy for renal cell carcinoma. METHODS: Data were collected from 147 patients who underwent potentially curative radical nephrectomy for renal cell carcinoma. The following data were analyzed: tumor pathology, patient demographics and clinical parameters, such as pre- and postoperative estimated glomerular filtration rate, as well as the cause of death. Cause-specific survival rates were calculated including deaths caused by renal cell carcinoma and cardiovascular disease. A Cox proportional hazard model was used for statistical analysis. RESULTS: A univariate analysis showed that age at surgery (≥70 years), postoperative estimated glomerular filtration rate (<45 mL/min/1.73 m(2)), pathological high T stage, grade and venous invasion were significant poor prognostic indicators. The multivariate analysis provided evidence that pathological venous invasion was a significant poor prognostic indicator, whereas age at surgery (≥70 years), pre- (<65 mL/min/1.73 m(2)) or postoperative (<45 mL/min/1.73 m(2)) estimated glomerular filtration rate and pathological high grade were significant poor prognostic indicators in T1 tumor cases. CONCLUSIONS: Post-radical nephrectomy renal function insufficiency can lead to a poor prognostic outcome, especially in patients with T1 renal cell carcinoma. Physicians should consider a comprehensive follow up focusing on possible causes of death, including those related to both renal cell carcinoma and cardiovascular disease events after radical nephrectomy.

OBJECTIVE: In order to characterize the significance of immune system function in patients with advanced renal cell carcinoma (RCC), we investigated the interactive relationships among the following parameters: metastatic characteristics, expression of Fas ligand (FasL) in nephrectomized specimens, immunological parameters, and patient's prognosis. MATERIALS AND METHODS: Thirty-five patients with advanced RCC were stratified into 3 groups according to the characteristics of metastasis timing, at first presentation (mFP), within 5 years of nephrectomy (early-recurrence), after 5 years (late-recurrence). Immunological parameters [hemoglobin, lymphocyte count, neutrophil/lymphocyte ratio (NLR), serum albumin, Eastern Cooperative Oncology Group (ECOG) performance status (PS), and Charlson Comorbidity Index], FasL expression in RCC, and patient prognosis from occurrence of metastasis were compared among the groups. Thirty-five patients were also stratified into 2 groups according to FasL positivity and individual parameters. Patient's prognosis and the remaining immunological parameters were compared between groups. RESULTS: The NLRs of the late-recurrence group were significantly lower than those of the mFP (P = 0.0004) and early-recurrence (P = 0.013) groups. The FasL mRNA positivity of the late-recurrence group was significantly lower than those of the mFP (P = 0.001) and early-recurrence (P = 0.0277) groups. The prognosis of the late-recurrence group was significantly better than that of the early-recurrence group (P = 0.0255). NLRs were significantly lower in the FasL-negative group than in the -positive group (P = 0.0182). The cause-specific survival rates of the ECOG PS 0 group were significantly higher than that of the ECOG PS > 0 group (P < 0.0001). CONCLUSIONS: Our results suggest the associations of the prognosis in advanced RCC with peripheral blood NLR and FasL expression in nephrectomized tumor. The characteristics of lower values of NLR and FasL expression positivity in late-recurrence compared with other metastatic timings suggest strong host immune activity, and may imply relatively long survival. On the other hand, elucidation of the patient's general condition obtained not only by chemical data but also by ECOG PS is crucial in the management of patients with advanced RCC.

PURPOSE: To evaluate the clinical significance of preoperative biomarkers such as laboratory data, Eastern Cooperative Oncology Group Performance Status (ECOG PS) and clinicopathological factors in patients undergoing radical nephroureterectomy for upper urinary tract urothelial carcinoma. METHODS: Between 1995 and 2011, a total of 99 patients treated at our institution for upper urinary tract urothelial carcinoma were enrolled in this study. The prognostic significance of various preoperative data and clinicopathological factors were analyzed. Univariate and multivariate analyses were performed using the Kaplan-Meier method with the log-rank test and a Cox proportional hazards regression model. RESULTS: Median patient age was 73 years (range 44-86 years), and the median follow-up period after radical nephroureterectomy was 37.9 months (range 6.6-171.4 months). The 5-year intravesical recurrence-free survival and cancer-specific survival estimates were 47.1 and 70.0 %, respectively. On multivariate analysis, concomitant bladder carcinoma was an independent predictor of intravesical recurrence (hazard ratio 3.689; P = 0.002), and infiltration (hazard ratio 14.842; P = 0.002), preoperative serum creatinine level (hazard ratio 9.992; P = 0.005), preoperative serum hemoglobin level (hazard ratio 6.370; P = 0.018) and ECOG PS (hazard ratio 4.326; P = 0.037) were associated with worse cancer-specific survival. This study is limited by biases associated with its retrospective design. CONCLUSIONS: This study indicates that not only clinicopathological factors, but also preoperative biomarkers, such as serum creatinine and hemoglobin levels and ECOG PS, predict a poor survival in patients with upper urinary tract urothelial carcinoma.

OBJECTIVES: To investigate Fas, Fas ligand (FasL) and Bcl-2 expression, which are considered to be important apoptotic regulatory factors in renal cell carcinomas (RCCs). PATIENTS AND METHODS: mRNA quantification and immunohistochemistry allowed for the determination of the expression of these three factors in surgically resected tumors from 82 patients with RCC. The correlation of protein and gene expression with more than 10 years of survival data following nephrectomy (along with clinical and pathologic parameters) was analyzed using uni- and multivariate statistical models. RESULTS: A significantly poorer outcome was observed in patients with tumors expressing high levels of Fas mRNA in the multivariate analysis (p = 0.0002). In addition, patient survival was significantly worse in FasL mRNA-positive tumor cases when compared with FasL mRNA-negative cases (p = 0.0345). Ten cases relapsed more than 5 years after nephrectomy. Among them, the tumors of 8 cases (80%) did not express FasL mRNA. Analysis of Bcl-2 did not show statistical significance of Bcl-2 expression as a prognostic indicator. CONCLUSIONS: The data suggest that pronounced Fas expression is a surrogate biomarker of active cancer cell proliferation. Given the FasL tumor counterattack theory, FasL overexpression in RCC may be one of the host immune deficiencies, consequently leading to poor prognosis.

INTRODUCTION: This study determines prognostic factors in patients with advanced urothelial cancer (UC) treated with gemcitabine-cisplatin or carboplatin (GC). MATERIAL AND METHODS: The clinical records of 30 patients with advanced UC treated with GC were retrospectively reviewed. Twenty-six patients (86.7%) had previously undergone other chemotherapies. Hematological parameters such as: neutrophil, lymphocyte and platelet counts; hemoglobin, C-reactive protein (CRP), and albumin levels; pain score; primary tumor site; tumor grade; type of platinum anti-cancer drug; and performance status before treatment were evaluated. Survival rates were calculated using the Kaplan-Meier method and analyzed using the log-rank test. Multivariate analysis was performed using a Cox proportional hazards model. RESULTS: The median cancer-specific survival (CSS) was 12.5 months. The overall response rate (ORR) was 30.0%. The survival rates of patients with low serum albumin (<3.5 g/dL; P = 0.008), low hemoglobin (<10.1 mg/dL; P = 0.025), high CRP (>1.0 mg/dL; P = 0.001), and a positive pain score (P = 0.002) were significantly worse than those with better blood values and pain scores. Multivariate analysis revealed serum CRP level as an independent prognostic indicator with a hazard ratio of 4.608 (95% confidence interval (CI) of 1.763-12.047; P = 0.002). CONCLUSIONS: Pretreatment serum CRP levels could be an accurate biomarker of the survival of patients with advanced UC before GC therapy. Although this is a preliminary study with a small sample size, these results seem to be very useful in clinical practice and our findings should be confirmed in a larger group of patients.
