Pulmonary metastasis from urothelial carcinoma of the upper urinary tract 29 years after nephrectomy.

ABSTRACT: Late pulmonary metastasis from urothelial carcinoma (UC) of the upper urinary tract is extremely rare.A 76-year-old man was referred to our hospital due to an abnormal shadow on chest X-ray. He had a history of left nephrectomy with a diagnosis of UC in the renal pelvis 29 years previously. Computed tomography showed a mass lesion in the right middle lobe of the lung that measured 4.9 cm in diameter. A transbronchial biopsy revealed the tumor to be metastatic pulmonary UC, and he underwent right middle lobectomy of the lung.Long-term postoperative follow-up of patients with UC might be necessary after radical nephrectomy.

Clinical Impact of Consolidative and Salvage Radiotherapy for Lymph Node Metastasis in Upper Urinary Tract Urothelial Carcinoma.

Project description:A 75-year-old Japanese male was referred to our institution for the evaluation of a left ureteral tumor in the ureterovesical junction. Computed tomography and pathologic examination under ureteroscopy revealed an invasive left ureteral urothelial carcinoma with left obturator nodal metastasis without distant metastasis. First, the patient underwent systemic chemotherapy (gemcitabine and cisplatin chemotherapy). We then performed left radical nephroureterectomy and extended lymph node dissection. Pathological examination revealed that the tumor was a high-grade invasive urothelial carcinoma with left common iliac and pelvic lymph node metastasis (pT3N2). Unfortunately, metastases appeared in the common iliac and para-aortic lymph nodes immediately after the operation; therefore, the previous first-line chemotherapy was readministered and second-line chemotherapy (gemcitabine and paclitaxel chemotherapy) was also performed. We also performed consolidative radiotherapy and salvage radiotherapy (boost, 20?Gy/10 fractions to the inferior para-aortic, and left common iliac regions containing swollen lymph nodes). The patient has shown no evidence of recurrence or metastasis even approximately 4 years after the initial diagnosis of advanced UUT-UC with lymph node metastasis. Our case suggests that consolidative or salvage radiotherapy combined with surgery and chemotherapy may provide clinical benefit for selected cases of advanced UUT-UC with lymph node metastasis.

Bladder tumor recurrence after urothelial carcinoma of the upper urinary tract.

Project description:Upper tract urothelial carcinoma (UTUC) is a relatively uncommon and poorly investigated malignancy, however, bladder recurrence after radical nephroureterectomy (RNU) is a frequent event. In this review, we summarize the current knowledge on risk prediction of bladder tumor recurrence after RNU, including surgical strategies and adjuvant intravesical treatments to reduce the risk of recurrence. Finally, we outline some of the more recent advances in genomics that will likely lead to new prognostic markers and risk stratification tools that may refine UTUC treatment in the future.

Recurrence pattern and TP53 mutation in upper urinary tract urothelial carcinoma.

Project description:TP53 mutation patterns are associated with prognosis of various cancers. This study was designed to investigate the association between TP53 mutation patterns and recurrence patterns in upper urinary tract urothelial carcinoma (UTUC) patients. A total of 165 consecutive UTUC patients who underwent nephroureterectomies were enrolled for measuring mutation patterns of TP53 gene from exome 2 to 11. Bladder recurrence, contralateral UTUC recurrence, and metastases were compared among groups by using log-rank test and Cox proportional hazard model. Single base substitution as an A:T to T:A transversion was noted in 55 (33.3%) patients (AT group). Forty-two (25.5%) patients had TP53 mutations with only other than A:T to T:A transversion (NAT group), and 68 patients (41.2%) had wide-type TP53 (WT group). AT group was predominately female (64%, 52%, 29%, respectively), had a higher incidence of end-stage renal disease (24%, 14%, 10%, respectively), and had more high-grade tumors (82%, 74%, 62%, respectively) compared to NAT and WT groups. With adjustment of tumor grade/stages, bladder and contralateral UTUC recurrence-free survival duration was shortest in NAT (p < 0.001) and AT group (p < 0.001), respectively. NAT group had a shorter metastasis-free survival duration than the other two groups combined (p = 0.018). As a result, A:T to T:A transversion increased contralateral UTUC recurrence risk, but other mutations in TP53 raised the hazard of bladder recurrence and metastases. Therefore, TP53 mutation pattern may be a useful biomarker to predict recurrence patterns of UTUC patients.

The clonal relation of primary upper urinary tract urothelial carcinoma and paired urothelial carcinoma of the bladder.

Project description:The risk of developing urothelial carcinoma of the bladder (UCB) in patients treated by radical nephroureterectomy (RNU) for an upper urinary tract urothelial carcinoma (UTUC) is 22% to 47% in the 2 years after surgery. Subject of debate remains whether UTUC and the subsequent UCB are clonally related or represent separate origins. To investigate the clonal relationship between both entities, we performed targeted DNA sequencing of a panel of 41 genes on matched normal and tumor tissue of 15 primary UTUC patients treated by RNU who later developed 19 UCBs. Based on the detected tumor-specific DNA aberrations, the paired UTUC and UCB(s) of 11 patients (73.3%) showed a clonal relation, whereas in four patients the molecular results did not indicate a clear clonal relationship. Our results support the hypothesis that UCBs following a primary surgically resected UTUC are predominantly clonally derived recurrences and not separate entities.

Molecular Characterization of Urothelial Carcinoma of the Bladder and Upper Urinary Tract.

Project description:PURPOSE:A better understanding of the molecular basis of urothelial carcinoma (UC) is needed to refine the clinical decision-making process. METHODS AND MATERIALS:We performed next-generation sequencing to investigate the mutational and transcriptional profiles of commonly mutated genes in UC using Ampliseq v2. Copy number variations (CNVs) were detected with nCounter assay. Genetic alterations between upper tract UC (UTUC) and urinary bladder UC (UBUC) were compared. RESULTS:Tumor samples from 31 UTUC and 61 UBUC patients were included in analysis. The two groups showed similar clinicopathologic features including tumor grade and stage. Median survival was longer in UTUC than UBUC patients, though this was statistically nonsignificant (59 vs 41 months, P=.137). In total, we found 982 genetic alterations from 92 samples: single nucleotide variants were the most common type of somatic mutation (479/508, 94.3%). Frequently detected somatic mutations included TP53 (68.5%), KDR (41.3%), and PIK3CA (17.4%). Notably, RB1 mutations were the only mutations significantly different between the UBUC and UTUC groups (19.7% vs. 0%, P=.020). The most common types of CNVs included amplifications (56/62, 90.3%): 17.7% of patients identified amplifications in NOTCH1. We also identified five translocations in the entire study population, including one case with FGFR3-TACC3 (Chr4) fusion. CONCLUSION:Within a small study population, we identified similar genetic alterations in both UTUC and UBUC patients, indicating a basis for similar management strategies.

STAT3 expression is a prognostic marker in upper urinary tract urothelial carcinoma.

Project description:Signal transducer and activator of transcription 3 (STAT3) plays a prominent role in the growth and invasion of several types of solid tumors. In this study, to assess the expression status and prognostic significance of the STAT3 pathway in upper urinary tract urothelial carcinoma (UTUC), we immunohistochemically stained for STAT3 and STAT3 pathway proteins, sphingosine-1-phosphate receptor 1 (S1PR1) and interleukin-6 (IL-6), in a tissue microarray containing 99 UTUC specimens. There were no significant associations between STAT3, S1PR1, or IL-6 expression pattern and tumor grade or pT stage. However, the patients with high STAT3 tumor had a significantly higher risk of both disease progression (p = 0.009) and cancer-specific mortality (p = 0.009), but not with tumors expressing S1PR1 or IL-6. High STAT3 expression in the nucleus was also associated with a significantly higher risk of both disease progression (p = 0.003) and cancer-specific mortality (p = 0.034). Multivariate analysis revealed that high STAT3 expression in the nucleus was significantly associated with cancer-specific survival after adjustment for pathological stage, lymph node involvement, lymphovascular invasion, and tumor grade (HR = 2.136, 95% CI = 1.009-4.767, p = 0.047). Our findings indicated that STAT3 could be a cancer-promoting factor and potentially a significant prognostic factor in UTUC.

Future strategies to enhance kidney preservation in upper urinary tract urothelial carcinoma.

Project description:Though radical nephroureterectomy remains the gold standard treatment for high grade or invasive disease in upper tract urothelial cancer (UTUC), kidney-sparing surgery has become preferred for low risk disease, in order to minimize morbidity and preserve renal function. Many methods exist for endoscopic management, whether via an antegrade percutaneous or retrograde ureteroscopic approach, including electroresection, laser ablation, and fulguration. There has been an increase in use of adjuvant intracavitary therapy, predominantly using mitomycin and bacillus Calmette-Guerin (BCG), to reduce recurrence after primary endoscopic management for noninvasive tumors, although efficacy remains questionable. Intraluminal BCG has additionally been used for primary treatment of CIS in the upper tract, with around 50% success. Newer investigations include use of narrow band imaging or photodynamic diagnosis with ureteroscopy to improve visualization during diagnosis and treatment. Genomic characterization may improve selection for kidney-sparing surgery as well as identify actionable mutations for systemic therapy. The evolution in adjuvant management has seen strategies to increase the dwell time and the urothelial contact of intraluminal agents. Lastly, chemoablation using a hydrogel for sustained effect of mitomycin is under investigation with promising early results. Continued expansion of the armamentarium available and better identification and characterization of tumors ideal for organ-sparing treatment will further improve kidney preservation in UTUC.

Ureteroscopic biopsy of upper tract urothelial carcinoma and role of urinary biomarkers.

Project description:Ureteroscopic biopsy is an integral part of diagnosis of urothelial carcinoma of the upper urinary tract. It can be a technical challenge, but diagnostic rates have improved remarkably with refinements in surgical technique and specimen processing. Cytology aids with diagnosis and other urinary biomarkers continue to evolve, which may help further stratify patients for treatment. The current literature on the ureteroscopic biopsy and role of urinary biomarkers is reviewed and summarized below.
