High Infiltration of CD163-Positive Macrophages in Intratumor Compartment Predicts Poor Prognosis in Patients With Upper Urinary Tract Urothelial Carcinoma and Radical Nephroureterectomy. Clin Genitourin Cancer 2023; 21:e386-e393. [PMID: 37244798 DOI: 10.1016/j.clgc.2023.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 05/02/2023] [Accepted: 05/04/2023] [Indexed: 05/29/2023]
Abstract
OBJECTIVES To investigate the prognostic value of CD68- and CD163-positive macrophages in patients with upper urinary tract urothelial carcinoma (UTUC). PATIENTS AND METHODS This retrospective study enrolled 50 patients (34 men and 16 women) with UTUC who received radical nephroureterectomy (RNU). We evaluated the expression of CD68 and CD163 in the intratumor compartment by immunohistochemistry. The Kaplan-Meier method and Cox proportional hazards regression model were used to evaluate overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and bladder recurrence-free survival (BRFS). RESULTS High infiltration of CD163-positive macrophages in patients with UTUC was significantly correlated with worse OS, CSS, and RFS (P < .05 for all). Multivariate analysis showed that high infiltration of CD163-positive macrophages was an independent negative prognostic factor of OS and CSS in patients with UTUC who received RNU. Lymphovascular invasion was an independent negative prognostic factor of RFS, and high infiltration of CD68-positive macrophages was an independent positive prognostic factor of BRFS. CONCLUSION This study indicated that high infiltration of CD163-positive macrophages in the intratumor compartment might be a useful prognostic marker for survival in patients with UTUC who receive RNU. Further, high infiltration of CD68-positive macrophages in the intratumoral compartment might be a useful prognostic marker for bladder recurrence in these patients.

Abstract
BACKGROUND Taiwan has the highest incidence of upper tract urothelial carcinoma (UTUC) worldwide. Although many pathological factors can predict the prognosis of UTUC, previous studies have rarely discussed perineural invasion (PNI). Therefore, we aimed to investigate the effect of PNI on a well-established cohort of patients with UTUC. METHODS This retrospective study included 803 patients with non-metastatic UTUC who underwent radical nephroureterectomy between June 2000 and August 2019. Demographic and clinicopathological parameters, including PNI, were collected for analysis. Using the Kaplan-Meier method and Cox proportional hazards model, we evaluated the significance of PNI with respect to progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS The median follow-up was 30.9 months, and there were 83 cases of PNI (10.3%). PNI-positive patients had unfavorable pathological features, including high pT stage, positive lymph node involvement, high tumor grade, and more lymphovascular invasion (all p < 0.001). Kaplan-Meier analysis showed that PNI was significantly associated with PFS, CSS, and OS (all p < 0.00001), and when combined with lymphovascular invasion, patients could be divided into groups with distinct survival rates (all p < 0.00001). In multivariate analysis, PNI was an independent factor leading to worse PFS (hazard ratio [HR] 1.72, 95% confidence interval [CI] 1.19-2.50; p = 0.004), CSS (HR 2.54, 95% CI 1.58-4.10; p = 0.0001), and OS (HR 1.78, 95% CI 1.19-2.65; p = 0.005). CONCLUSIONS We demonstrated an association between PNI and the prognosis of UTUC. Routine assessment of PNI in UTUC with standardized protocols may help achieve better risk stratification and subject selection for perioperative treatment.

Abstract
Recent research in next-generation sequencing characterized the genomic landscape of urothelial cancer. However, the majority of the studies focused on bladder cancer (BC). Upper urinary tract urothelial carcinomas (UTUC) and BC share some histological characteristics, but, considering the differences in terms of embryologic precursors, epidemiology, genetics, medical and surgical management and response to therapy, UTUC and BC should be considered as two distinct diseases. Our objective is to analyze through a literature search the latest updates and the current knowledge about the genomics of UTUC. We also evaluate genetic differences between BC and UTUC and the potential implications for systemic therapy. Molecular subtyping and variant histology and their correlation with response to chemotherapy were also explored. In summary, the most frequent genomic variations in UTUC included FGFR3, chromatin remodeling genes, TP53/MDM2 and other tumor suppressors/oncogenes. The genomics of UTUC, integrated with clinical data, could drive the selection of patients who could benefit from targeted therapy or off-label treatment. Routine implementation of tumor genomic characterization in UTUC patients should therefore be contemplated and evaluated prospectively.

Abstract
Upper tract urothelial carcinoma (UTUC) is a rare and aggressive disease that is associated with high rates of recurrence and death. Radical nephroureterectomy (RNU) with excision of the bladder cuff is considered the standard of care for high-risk UTUC, whereas kidney-sparing techniques can be indicated for select patients with low-risk disease. There is a significant lack of clinical and pathological prognostic factors for stratifying patients with regard to making treatment decisions. Incorporation of tissue-based molecular markers into prognostic tools could help accurately stratify patients for clinical decision-making in this heterogeneous disease. Although the number of studies on tissue-based markers in UTUC has risen dramatically in the past several years-many of which are based on single centers and small cohorts, with a low level of evidence-many discrepancies remain between their results. Nevertheless, certain biomarkers are promising tools, necessitating prospective multi-institution studies to validate their function.

Abstract
BACKGROUND Inactivating mutation and consequent expression loss of stromal antigen 2 (STAG2, also known as SA2), a component of the cohesion complex, is one of the most common genetic aberrations in urothelial carcinoma. However, the clinicopathologic or prognostic significance of STAG2 alterations in upper tract urothelial carcinoma (UTUC) is largely unknown. METHODS This study immunohistochemically examined the expression of STAG2 in 171 patients with UTUC. The correlations of STAG2 loss with clinicopathologic features and patients' prognoses were examined. RESULTS Loss of STAG2 expression was observed in 28 cases (16%). Loss of STAG2 was significantly correlated with histological low grade, papillary architecture, noninvasive tumors, absence of concomitant carcinoma in situ, and lower Ki-67 expression. Loss of STAG2 alone was not significantly associated with patients' prognoses in either the uni- or multivariate analysis. However, STAG2 loss was significantly associated with worse clinical outcome in UTUC with high Ki-67 proliferation indexes, but not in UTUC with low Ki-67 expression. CONCLUSIONS Loss of STAG2 was generally associated with less aggressive features in UTUC. However, the STAG2 loss was an ominous sign in the subpopulation with higher Ki-67 proliferation indexes. Examining both STAG2 and Ki-67 status may be useful for identifying aggressive clinical behavior of UTUC.

Abstract
Urothelial carcinoma is a highly heterogeneous disease that can arise throughout the entire urothelial lining from the renal pelvis to the proximal urethra. Upper tract urothelial carcinoma (UTUC) is rare, and while it shares many similarities with urothelial carcinoma of bladder (UCB), there are also significant differences between UTUC and UCB regarding clinical management and outcomes. No major advances have been made recently in the development of new systemic therapies for urothelial carcinoma, partly due to the lack of understanding of underlying molecular pathogenetic mechanisms. In the past decade, the emergence of next-generation sequencing has greatly enabled genomic characterization of tumor samples. Researchers are currently exploring a personalized approach to augment traditional clinical decision-making based on genetic alterations. In the present review, we summarize current genomic advances in UTUC and discuss the potential implications of these developments for developing prognostic and predictive biomarkers.

Abstract
INTRODUCTION Tumor stage and grade represent the best established predictors for the prognosis of upper tract urothelial carcinoma (UTUC). However, controversies still exist regarding the role of tumor necrosis, location, and multifocality in the prognosis of UTUC. We share our experience with 305 patients, reporting on the pathologic features in detail, cancer characteristics, and survival. MATERIALS AND METHODS We retrospectively reviewed the data from patients who had undergone surgery for UTUC from 1983 to 2013. The tumors were staged according to the 1997 TNM classification and the 3-tiered World Health Organization grading system. Cancer-specific survival (CSS) was estimated using the Kaplan-Meier method. RESULTS A total of 305 patients were eligible for analysis. The 5-year CSS for grade 1, 2, and 3 was 88%, 84%, and 60%, respectively. The CSS for stage pT1, T2, T3, and T4 was 82%, 70%, 62%, and 0%, respectively. On univariate analysis, tumor stage, tumor grade, positive lymph node status, and micropapillary invasion had adverse effects on survival (P = .006, P = .045, P = .01, and P = .005, respectively). On multivariate analysis, only stage and micropapillary variant maintained significance (P = .01). Multicentricity and tumor location affected CSS in the early follow-up period but did not in the late follow-up period. Neither carcinoma in situ nor adverse pathologic variants affected survival. CONCLUSION The tumor stage and presence of a micropapillary variant are of paramount prognostic significance for survival in patients with UTUC. The tumor grade and lymph node status are also good predictors. In our series, multifocality and tumor location affected early and mid-term survival with no significant effects on late survival.

Abstract
OBJECTIVE Determine whether the overexpression p53, MIB-1 and PECAM-1 of protein levels is of interest in predicting the prognosis of transitional cell carcinoma of the upper urinary tract (TCC-UUT) with the primary seat in the renal pelvis. MATERIAL AND METHOD A univariate and multivariate analysis was conducted for prognosis prediction in a series of 82 patients with TCC-UUT of the renal pelvis who had no metastases at diagnosis (N0/Nx M0) and were treated exclusively with nephroureterectomy. We assessed clinicopathological parameters (age, gender, tumor grade and extent, histological variety, growth pattern, vascular invasion, infiltration of the renal parenchyma, tumor necrosis) and the immunohistochemical expression of p53, MIB-1 (ki-67) and PECAM-1 (CD31) in sections performed with tissue microarray (TMA). RESULTS A total of 47.6% of the patients had high-grade lesions according to the USIP-WHO classification. The growth pattern was flat in 15.85%. The distribution by T category was: 3.7% pTa, 51.2% pT1, 11% pT2, 29.3% pT3 and 4.9% pT4. The mean follow-up was 46.8+38.5 (range, 4-172) months. The median survival was reached at 57 (95% CI 44-63) months. The univariate analysis revealed that survival in these patients is associated with tumor size (P=.028), histological variety (P<.0001), growth pattern (P<.0001), grade (P<.0001), pT (P=.01), vascular invasion (P=.025), necrosis (P=.004) and overexpression of p53 (P=.0006), PECAM-1 (P=.0036) and MIB-1 (P=.0038). The Cox regression model showed that high-grade (HR, 4.2; 95% CI 1.28-13.79; P=.018), flat growth pattern (HR, 2.52; 95% CI 1.05-6.03; P=.038) and p53 overexpression (HR, 2.8; 95% CI 1.22-6.44; P=.015) were independent predictors. CONCLUSION Histological grade, tumor growth pattern and p53 overexpression were established as the primary predictors of prognosis for primary TCC-UUT of the renal pelvis. The independent value of MIB-1 observed in other studies was not reproduced in this study.

Abstract
BACKGROUND Bcl-xL has an important role in the control of cell death through its inhibition of apoptosis. The aim of this study was to investigate the clinicopathological significance of Bcl-xL in upper urinary tract urothelial carcinoma (UTUC) and the therapeutic effect of targeting Bcl-xL protein in urothelial carcinoma (UC) cells. METHODS We evaluated the immunohistochemical expression of Bcl-xL in 175 UTUC patients to determine the clinical role of Bcl-xL expression in clinical outcome. We used bafilomycin A1 (BMA) as a specific inhibitor of Bcl-xL to examine the biological effects in UC cells in vitro and in vivo. RESULTS Immunohistochemical analysis of Bcl-xL expression revealed that patients with a high Bcl-xL score had a significantly lower 5-year cancer-specific survival (CSS) rate (53.2%) than those with a low Bcl-xL score (77.2%) (P=0.0011). Multivariate analysis indicated that a high Bcl-xL score was an independent prognostic factor of CSS (P=0.023). BMA inhibited UMUC-3 cell proliferation in vitro by induction of apoptosis. Treatment with BMA significantly inhibited tumour growth in UMUC-3 tumours in this mouse xenograft model accompanied by an elevated apoptosis induction. CONCLUSION Bcl-xL appears to be a significant molecular marker for the prognosis of UTUCs. Targeting Bcl-xL may be a promising therapeutic strategy for patients with UC.

Abstract
A 61-year-old man was referred to our hospital with the chief complaint of right leg weakness. Abdominal magnetic resonance imaging (MRI) and computed tomography (CT) demonstrated a ureteral tumor and a neighboring massive retroperitoneal tumor in addition to retroperitoneal lymph node and right renal metastases. The tumor was diagnosed as upper tract urothelial carcinoma (cT4N1M1) by percutaneous tumor biopsy. As the patient achieved a partial response after three courses of combination chemotherapy with gemcitabine and cisplatin, he received total nephroureterectomy and lymph node dissection. The pathology showed no viable cancer cells, demonstrating a pathological complete response. He remains alive after 26 months with no evidence of disease.

Abstract
The management of upper urinary tract urothelial carcinoma (UUT-UC) is controversial. Radical nephroureterectomy is a major undertaking and has obvious shortcomings in the presence of renal impairment and solitary kidneys, whereas endoscopic management can be associated with a risk of disease progression. There is a pressing need for reliable predictive biomarkers to refine patient selection for renal conservation. p53 is the most frequently investigated molecular marker in UUT-UC. Of the 24 papers published on the subject, expression of p53 is a significant univariate prognostic marker in 12 publications, representing seven unique cohorts. However, multivariate analysis demonstrates that p53 expression is of independent prognostic significance in only five studies, all of which contain potential statistical bias. The currently available data do not, therefore, support a role for p53 in this regard, and suggest a need for prospective large-scale collaborative studies using standardized methods of p53 detection and statistical analysis.

Abstract
We investigated the expression of apoptosis-related markers and their association with the clinical outcomes of patients with urothelial carcinoma of the upper urinary tract. A total of 112 patients with urothelial carcinoma of the upper urinary tract that had surgery from March 1998 to July 2005 were included in the study. Tissue microarray slides were used for immunohistochemistry, and immunohistochemical staining was performed to investigate the association of apoptosis-related markers with clinical outcome. Apoptosis was confirmed by the TdT-mediated DUTP nick-end labeling method to obtain the apoptotic index. Survival analysis was performed according to the Kaplan-Meier method, and the Cox proportional hazard regression model was used to compare the relative influence of different prognostic factors. Among the 112 patients, 32 (28.6%) had altered expression of p53, 30 (26.8%) of bcl-2, 62 (55.4%) of bax, 27 (24.1%) of caspase-3, and 23 (20.5%) of survivin. The expression of p53 and caspase-3 was associated with the pathologic grade (P = .035 and P = .004, respectively). Altered expression of caspase-3 was associated with the pathologic stage (P = .016). The multivariate analysis showed that the expression of survivin (hazard ratio 2.91, 95% confidence interval 1.07-7.90, P = .036) and the apoptotic index (AI) (3.35, 1.06-10.56, P = .039), as well as the T and N stages (P = .043 and P = .010, respectively) were significantly associated with the disease-specific survival. Our results suggest that survivin expression and a high apoptotic index were poor prognostic factors for survival in patients with urothelial carcinoma of the upper urinary tract. These results may help to identify a subset of patients who require adjuvant therapy or closer follow-up.

Abstract
Clinicopathologic features predictive of patient outcome in upper urinary tract urothelial carcinoma are not well defined. The aim of this study was to assess the role of pT classification, tumor grade, and vascular invasion in predicting metastasis-free survival. A total of 190 consecutive invasive upper urinary tract urothelial cancers operated between 01/1984 and 12/2004 were re-evaluated with respect to pT classification, tumor grade (according to the three-tiered WHO 1973 and the recent two-tiered grading system following the WHO/ISUP consensus classification), as well as presence of lymph and/or blood vessel invasion. Prognostic impact was analyzed using the Kaplan-Meier method and the Log-Rank test. For multivariate testing, a Cox's proportional hazards regression model was used. pT1 was present in 81 (43%), pT2 in 29 (15%), pT3 in 73 (38%), and pT4 in seven (4%) cases. There were 12 (6%) G1, 96 (51%) G2, and 82 (43%) G3 tumors or 84 (44%) low-grade and 106 (56%) high-grade tumors according to the two-tiered system. The presence of vascular invasion in 72/190 (38%) tumors was associated with high pT classification (P<0.001) and high tumor grade (P<0.001). Disease progression occurred in 39% of patients, with 5- and 10-year metastasis-free survival rates of 56 and 45%, respectively. On univariate analysis, all investigated parameters showed prognostic significance. The negative influence of vascular invasion on patient outcome was strikingly strong in high pT classification and high-grade cancers. On multivariate analysis, pT classification (P<0.001) and vascular invasion (P<0.001) proved to be independent prognostic factors, whereas tumor grade according to the two-tiered system missed statistical significance (P=0.06). In conclusion, pT classification and vascular invasion are independent prognostic factors with respect to metastasis-free survival and should be used to guide adjuvant therapy strategies in affected patients. Presence (or absence) of vascular invasion should be commented upon separately in the pathology report.

Abstract
AIM To investigate the prognostic and predictive relevance of p53 protein, Ki-67 antigen, MMP-2 and MMP-9 in patients with transitional cell carcinoma (TCC) of the upper urinary tract. METHODS The expression of p53 protein, Ki-67 antigen, MMP-2 and MMP-9 was examined by immunohistochemistry in 69 patients with TCC of the upper urinary tract. Correlation of p53, Ki-67, MMP-2 and MMP-9 over-expression with conventional pathological parameters and patient survival was examined. RESULTS p53 over-expression was significantly correlated with histological grade (P < 0.05), but not with pathological stage, vascular invasion, lymphatic invasion or lymph node metastasis. Ki-67 over-expression was significantly correlated with stage, grade, lymphatic invasion and vascular invasion (P < 0.05). In survival analyses, Ki-67 over-expression was a significant prognostic factor in the univariate analysis (P < 0.05), but it did not have a significant impact on survival in the multivariate analysis. Ki-67 labeling index was a significant prognostic factor in patients with a low p53 labeling index, but not in patients with a high p53 labeling index. CONCLUSION Ki-67 over-expression is of prognostic value in TCC of the upper urinary tract, while p53, MMP-2 and MMP-9 are of limited value.

Abstract
OBJECTIVES Evaluate prognostic information of anatomical location in patients with upper tract transitional cell carcinoma (UTTCC). METHODS Retrospective analysis of 149 upper tract transitional cell carcinoma (UTTCC) patients from a single institute treated surgically between 1988 and 2003. RESULTS Transmural tumor growth (pT3 or pT4) was less common in distally located tumors (33%) compared to mid (44%), proximal ureter (75%) or pyelum tumors (41%). Tumor stage was the best predictor of disease specific survival. Distally located tumors had a significantly better survival than proximally located cancers (median survival 53 months versus 16 months for tumors in the proximal ureter). Bladder cancer was found in 73 (49%) patients. Invasive UTTCC were less likely to be associated bladder cancer (RR 0.66, 95%CI 0.43-0.98). In a multivariate analysis both tumor stage and location in the upper tract were predictive of disease specific survival after UTTCC diagnosis. CONCLUSION Tumor location in the proximal upper tract predicts stage-independent poor prognosis in patients with UTTCC.

Abstract
PURPOSE We retrospectively assessed the clinical significance of anti-p53 antibody (S-p53Ab) status in the serum of patients with upper urinary tract tumors. MATERIALS AND METHODS Enzyme-linked immunosorbent assay was used to analyze S-p53Abs in 63 upper urinary tract tumors. Its incidence and clinical or pathological background were analyzed in comparison with 80 bladder tumors. RESULTS The prevalence of S-p53Abs in patients with upper urinary tract tumors was higher than that in patients with bladder tumors (27.0% vs 17.5%). Especially, 34.8% of patients showed positive S-p53Abs in invasive upper urinary tract tumors (pT1 or more). In upper urinary tract tumors the prevalence of S-p53Abs significantly correlated with higher grade (p <0.01), higher stage (p = 0.02), positive lymph nodes (p = 0.03) and p53 nuclear accumulation (p <0.01). However, disease specific survival after nephroureterectomy did not differ between patients with negative and positive S-p53Abs. CONCLUSIONS Our data suggest the possibility of the clinical application of S-p53Abs, especially for the detection of high grade or high stage tumors in the upper urinary tract. However, the usefulness of S-p53Abs as prognostic marker seems to be extremely limited in patients with urothelial tumors.

Abstract
OBJECTIVES To establish whether high microsatellite instability (MSI) (present in almost 20% of cases) and loss of MSH2 protein expression (sometimes used to predict MSI status) are prognostic factors of overall survival for patients with invasive upper urinary tract transitional cell carcinoma (UUT-TCC). UUT-TCC has a poor prognosis (overall survival less than 50% at 5 years). METHODS The files of 80 patients who underwent nephroureterectomy for invasive UUT-TCC (Stage pT2 or worse) between 1990 and 2002 were reviewed. The following data were collated: age at diagnosis, prior history of cancer, tobacco consumption, tumor stage and grade, and disease progression. MSI was determined by polymerase chain reaction/fragment analysis and MSH2 protein expression by immunohistochemistry on retrieved tumor tissue. RESULTS The median patient age was 71.5 years. The male/female ratio was 2.8. High MSI and loss of MSH2 expression were encountered in the tumors of 14 (17%) and 21 (26%) of the 80 patients, respectively. High MSI was significantly associated with patients with a better prognosis (Stage T2-T3N0M0; P = 0.02). The mean overall survival was 22.5 +/- 18 months (range 6 to 78). In univariate analyses, age, stage, tumor grade, high MSI, and loss of MSH2 expression were related to better overall survival (37 +/- 22 months, P = 0.003; 34 +/- 22 months, P = 0.02). Only stage, age, and high MSI were prognostic factors in a multivariate analysis (P < 0.05). CONCLUSIONS MSI and expression of MSH2 are useful prognostic factors in invasive UUT-TCC. However, other than age and stage, only MSI was an independent factor. High MSI indicates a better prognosis, especially in patients younger than 71 years with Stage T2-T3N0M0.

Abstract
OBJECTIVES To describe 3 cases of tumors located in the kidney that may relate collecting (Bellini) duct carcinoma (CDC) to urothelial cell carcinoma (UC). We hypothesized that these distinct tumor types may share a common origin. CDC is a subtype of renal cell carcinoma associated with a highly aggressive course, poor prognosis, and limited response to immunotherapy, behaving similarly to UC. METHODS We present 2 cases of CDC and 1 case of UC of the renal papilla. We compared the clinical presentation and survival rate, together with the radiologic, histologic, and immunostaining (including p53) findings, with strong emphasis on the similarities. RESULTS One patient with CDC had a previous history of grade 3, Stage Ta bladder UC. The urothelial carcinoma from the kidney papilla (case 3) presented carcinoma in situ of the adjacent urothelium and displayed mixed characteristics with CDC, namely location, positive staining for Ulex europaeus and pyelonephritic changes. p53 staining showed marked positivity in the tumor of patient 2. Disease progression was rapid, with a median survival of 5.6 months (range 5 to 7). CONCLUSIONS The results of this study suggest that the broad category of renal cell carcinoma includes a spectrum of lesions. In this range of diseases, CDC might be distinct from conventional renal cell carcinoma but share biologic features with UC, with the consequent implications for management. This association between CDC and UC may reflect the common embryologic origin of collecting duct and urothelial cells, since they derive from progressive branching of the mesonephric (wolffian) duct. Furthermore, the differential cytogenetic expression profiles suggest that the molecular events underlying the development of distal nephron and proximal tubule renal cancers are distinct.

Abstract
OBJECTIVES To analyze p63 and p53 immunoreactivity of upper urinary tract transitional cell carcinoma with respect to prognosis. p63 is required for the differentiation of normal urothelium and is expressed in both non-neoplastic urothelium and transitional cell carcinoma of the bladder. METHODS A total of 53 upper urinary tract transitional cell carcinoma specimens were investigated immunohistochemically using a tissue microarray technique. p63 and p53 immunoreactivity was analyzed digitally with respect to associations with pT stage and grade and impact on disease-free survival. RESULTS p63 expression was detected in 51 (96.2%) of 53 cases. Normal expression (greater than 90% of tumor cell nuclei) was observed in 1 (4.5%) of 22 Stage pT3 compared with 13 (41.9%) of 31 Stage pT1-T2 tumors (P = 0.003) and 4 (16%) of 25 G3 compared with 10 (35.7%) of 28 G2 tumors (P = 0.13). p53 overexpression (more than 10% of tumor cell nuclei) was found in 10 (18.9%) of 53 cases, including 2 (6.5%) of 31 Stage pT1-T2 and 8 (36.4%) of 22 Stage pT3 (P = 0.011) and 0 of 28 G2 and 10 (40%) of 25 G3 tumors (P <0.001). Metastatic disease was observed in 14 (26.4%) of 53 patients, including none of 14 with normal p63 expression compared with 14 (35.9%) of 39 with decreased (less than 90% of tumor cell nuclei) p63 expression (P = 0.02) and 5 (50%) of 10 patients with p53 overexpression compared with 9 (20.9%) of 43 patients with p53-negative tumors (P = 0.01). Multivariate analysis proved Stage pT3 was the only independent prognostic factor. CONCLUSIONS Decreased p63 immunoreactivity and p53 overexpression were significantly associated with advanced tumor stages and poor prognosis. However, neither parameter was an independent prognostic factor in multivariate analysis.

Abstract
Purpose Radical surgery represents the treatment of choice for carcinoma of the upper urinary tract. Nevertheless, approximately 50% of patients with stage T ≥ 3 or lymph node involvement die from their disease, mainly as a result of the development of distant metastases. Therefore, there is a need for effective adjuvant systemic treatment. We prospectively studied a cohort of patients who underwent surgery for high-risk carcinoma of the upper urinary tract to assess the feasibility of the combination of paclitaxel and carboplatin as adjuvant treatment. Patients and Methods Thirty-six patients with tumor stage ≥ 3 or lymph node involvement were treated with four cycles of paclitaxel at 175 mg/m2 and carboplatin (area under the curve 5, Calvert Formula) every 3 weeks following surgery. Results Median follow-up was 40.6 months. Chemotherapy was well tolerated with 32 patients (89%) receiving full carboplatin and paclitaxel doses without delays. The most frequent grade 3/4 toxicity was neutropenia (39%), which was complicated with fever in only one case (3%). Nonhematologic grade 3 or 4 toxicities were reported in only one case. Five-year survival was 52% (95% CI, 35% to 69%), while 5-year disease-free survival was 40.2% (95% CI, 15.8% to 64.6%). Local failure rate was 30%, as opposed to 17% of patients who developed distant metastases. No patients with grade 2 tumors relapsed during follow-up, as opposed to 60% of patients with grade 3 tumors. Conclusion Adjuvant chemotherapy with paclitaxel and carboplatin is feasible and may reduce the risk of distant metastases in high-risk upper urinary tract carcinoma.

Abstract
Transitional cell carcinoma (TCC) of ureter and renal pelvis is relatively uncommon. Smoking, occupational carcinogens, analgesic abuse, Balkan nephropathy are the risk factors. Cytogenetic studies revealed that the most frequent aberration is the partial or complete loss of chromosome 9. Approximately 20-50% of patients with upper urinary tract (UUT) TCC have bladder cancer at some point on their course, whereas the incidence of UUT TCC after primary bladder cancer is 0.7-4%. Excretory urography and retrograde pyelography are the conventional diagnostic tools; however, ureteropyeloscopy combined with cytology and biopsy is more accurate. Grade and stage of the disease have the most significant impact on survival. Nephroureterectomy with bladder cuff excision has been the mainstay of treatment. Local resection may be appropriate for distal ureteral lesions especially when the disease is low grade and stage. Advances in endourology have made it possible to treat many tumors conservatively. Ureteroscopic and to a certain extent percutaneous surgical approaches are widely used today especially in patients with low grade, low stage disease. Endoscopic close surveillance is mandatory for these patients. Adjuvant topical therapies appear to be safe but confirmation of any benefits awaits the results of further large studies. More recently, laparoscopic techniques have become a viable alternative to open surgery, but long term cancer control data are lacking. Aggressive surgical resection does not affect the outcome of patients with advanced disease. Adjuvant radiotherapy is ineffective, and systemic chemotherapy results in a low complete response rate for patients with metastases.

Abstract
PURPOSE We evaluate the safety and efficacy of conservative elective treatment of upper urinary tract tumors, and determine predictive factors for recurrence and progression to optimize indications of this type of treatment. MATERIALS AND METHODS Since 1984 we have performed a prospective study of conservative treatment of single, low grade and stage, less than 3 cm. upper tract tumors. The study includes 54 patients with a normal contralateral kidney who had been followed for more than 36 months. Open conservative surgery was performed in 31 cases and endourological surgery in 23. Minimum followup was 36 months, maximum 210 and mean 84.8. Univariate and multivariate analyses of recurrence and progression were performed in relation to age, sex, association with a bladder tumor, bladder tumor stage and grade, sequence of bladder tumor in relation to upper urinary tract tumor, number of previous bladder tumor recurrences, association with bladder carcinoma in situ, upper urinary tract tumor grade, stage, location, size and therapy, and upper urinary tract cytology. RESULTS Of the 54 patients 19 (35%) had recurrence, which was bilateral recurrence in 4, and progression occurred in 9 (16%). At the end of analysis 44 (62.9%) patients were disease-free and alive at a mean time of 92.88 months, 13 (24%) died disease-free at a mean of 72.7 months and 7 (12.9%) died of disease at a mean of 97.85 months. Cause specific mortality occurred in 7 (12.9% cases). Among the 54 initially conservatively treated units 42 (77.7%) kidneys were ultimately preserved. On univariate and multivariate analysis tumor location in the renal pelvis and association with a previous multi-recurrent bladder tumor were variables significantly related to recurrence and progression, as well as bilateral recurrence. CONCLUSIONS Conservative treatment is an optional approach for select upper urinary tract tumors. The strongest risk factors for recurrence and progression were association with a previous multi-recurrent bladder tumor and tumor location in the renal pelvis but these conditions were also the strongest risk factors for bilateral recurrence. Conservative treatment can also be recommended in these cases but only with compliant patients and close followup.

Abstract
The use of neoadjuvant chemoradiotherapy prior to surgery in the treatment of oesophageal adenocarcinoma has increased in recent years, and up to 25% of patients will have a complete pathological response to the neoadjuvant therapy. Many patients will not respond, however, and the knowledge of molecular factors predicting response or resistance to chemoradiotherapy is required to enhance treatment results. An understanding of apoptosis and cell proliferation may be relevant and this study focused on apoptotic indices and cell-cycle related (Ki-67, p53 and bcl-2) protein expression in a cohort of 42 patients with primary oesophageal adenocarcinoma. We documented that apoptosis occurs among viable (proliferating) tumour cells in all adenocarcinoma cases examined in this study. Pre-operative chemoradiotherapy significantly increased apoptosis and significantly decreased cell proliferation (estimated by Ki-67 expression). Immunohistochemically detected p53 and bcl-2 gene products had no regulatory role in the apoptotic process. The cumulative expression of p53 protein is significantly associated with increasing proliferation activity. Evaluation of apoptosis in pre-treatment specimens may have potential utility in predicting the efficacy of treatment. Assessment of the tumours proliferation activity by Ki-67 expression might identify patients who are at risk of developing metastatic disease.

Abstract
BACKGROUND The significance of p53 overexpression for the prognosis of transitional cell carcinoma (TCC) of the renal pelvis and ureter remains controversial. Simultaneous evaluation of p53 and MDM2 may enable better prediction of tumor proliferation and patient prognosis than that obtained with evaluation of p53 alone. METHODS Immunohistochemical detection of p53 protein, MDM2 protein and Ki-67 antigen as proliferation markers was performed for tissue samples obtained from 74 patients with TCC of the renal pelvis and ureter. The correlations of p53/MDM2 overexpression with conventional pathological features, Ki-67 labelling index (LI) and patient survival were studied. RESULTS Overexpression of p53 was related to progression of each of the pathological features examined (grade, stage, type of infiltration, vascular invasion and lymphatic invasion) and Ki-67 LI was significantly higher with high p53 expression than with low p53 expression. However, overexpression of MDM2 was related to neither disease progression nor Ki-67 LI. Survival analyses were performed for 66 patients. Univariate analysis showed p53 to be a useful prognostic indicator, but in a multivariate analysis only type of infiltration and Ki-67 LI were independent survival markers, while p53 was not. Overexpression of MDM2 was unrelated to patient survival, and the combination of p53 and MDM2 for survival indication was found not to be useful. CONCLUSIONS Overexpression of p53 is related to disease progression, increased tumor proliferation and patient survival for TCC of the renal pelvis and ureter, but the independent prognostic value of p53 did not reach statistical significance. Combined analysis of MDM2 with p53 cannot be recommended for examination of the malignant potential of TCC of the renal pelvis and ureter.

Abstract
The optimal approach to upper tract TCC remains to be redefined. A routine nephroureterectomy for every filling defect in the upper urinary system, even in the case of a normal contralateral kidney, constitutes an unnecessary mutilation in more than two thirds of the cases. Nephroureterectomy does not reduce the need for a long-term cystoscopic follow-up because of the high rate of bladder tumor recurrence that may happen years later after nephroureterectomy. Relying solely on radiography and cytology, lacking sensitivity and specificity, to recommend a nephroureterectomy is against the principles of oncologic surgery, especially now that preoperative histologic proof is easy to obtain endoscopically without compromising cancer control. Ureteroscopy, rigid and flexible, provides a complete assessment of the upper urinary system. Biopsy specimens taken with ureteroscopy may be sufficient for grading but less adequate for staging of the tumor. The authors reserve ureteroscopy for ureteral tumors and small (< 1.5 cm) single tumors of the renal pelvis. They approach large or multiple tumors of the renal pelvis percutaneously, in which a full histologic assessment is possible along with a complete resection of the tumor. The decision on the therapeutic approach is made only after the final pathologic report is reviewed. Grade I and grade II superficial disease (Ta, T1) can be treated endoscopically with minimal morbidity and with an efficiency comparable with the standard more invasive nephroureterectomy (Table 5). The indications for endourologic treatment in these cases can be extended safely beyond a solitary kidney or a high surgical risk to include any healthy individual with a normal contralateral kidney who is willing to commit to a rigorous lifelong follow-up. Patients with grade II T1 lesions require a more vigilant follow-up. For grade III Ta disease, more caution should be exercised in selecting these patients for elective endourologic management. When criteria of good prognosis are found, such as absence of carcinoma in situ, presence of diploidy, low p53 expression and a single-tumor, endoscopic management can be offered [table: see text] with a closer follow-up and resorting always to immediate nephroureterectomy at the first evidence of upstaging. Because of the high incidence of recurrence and progression, elective endourologic management for grade III T1 tumors is not recommended. Endoscopic conservative surgery still can be offered in the cases of a solitary kidney or chronic renal insufficiency or for poor surgical candidates. Patients with localized stages (T2, T3) TCC should be offered immediate nephroureterectomy. The authors do not expect adequate endoscopic extirpation with muscle invasive tumors. Although the tissue removed may include deep layers, deep resection is precluded by the thin renal pelvic wall and the associated risk for perforation. Patients with more extensive disease (T3, T4) have a bad prognosis regardless of the form of therapy. Achieving local control percutaneously while preserving as many nephrons as possible for the future chemotherapy can be a reasonable option.

Abstract
PURPOSE Radiotherapy is widely used in the treatment of bladder cancer. The search for biological parameters that could select patients who will respond to radiation treatment has become essential. The aim of this study is to assess whether the pretreatment apoptotic index is useful in predicting local control and survival in a group of bladder cancer patients treated by radiotherapy. METHODS AND MATERIALS Fifty-five patients with invasive bladder carcinoma treated between 1983 and 1996 were included in this study. Radiotherapy was given to a median dose of 66 Gy, mean 63.28 Gy, in 1.8-2 Gy daily fractions. Apoptotic cells were studied in hematoxylin-eosin slides. Clinicopathological tumor characteristics were studied in relation to the apoptotic index, and as prognostic factors for local control and survival in both univariate and multivariate analysis. RESULTS Pretreatment apoptotic indexes were related to tumor stage, mitotic index, and Ki67 proliferation index. Five-year actuarial local control for the whole group was 45%. Patients with tumors showing low pretreatment apoptotic indexes had better local control (p < 0.037) and survival (p < 0.01) than highly apoptotic tumors. Tumor stage (T2 vs. T3-4) and the pretreatment apoptotic index were significant predictive factors for local control and survival in multivariate analysis. CONCLUSIONS The pretreatment apoptotic index is useful in predicting the clinical outcome of bladder cancer patients treated by radiotherapy. Assessment of biological tumor characteristics could allow the selection of patients for different treatment strategies.
