RESUMEN

AIMS: The recent changes in the American Joint Commission on Cancer, 8th edition (AJCC-8E) pT2 and pT3 tumour definitions for penile cancer need robust validation studies. A recent study redefined and modified the pT2 and pT3 stages incorporating the histopathological variables (tumour grade, lymphovascular invasion, perineural invasion) similar to that used in the current AJCC-8E pT1 stage tumour subclassification. In this study, we validate and compare this proposed staging with the AJCC staging systems on an external data set. METHODS AND RESULTS: The data set from a previously published study was obtained. pT2 and pT3 stages were reconstructed as per AJCC 7th edition (AJCC-7E), AJCC-8E and the proposed staging. The staging systems were correlated with nodal metastasis, disease-free survival (DFS), cancer-specific survival (CSS) and overall survival (OS). All systems were compared using receiver operating characteristic (ROC) curves. A total of 281 cases formed the study cohort. AJCC-8E (P = 0.031) and the proposed staging (P = 0.003) correlated with nodal metastasis on adjusted analysis, the latter with a better strength of association (AJCC-8E, γ = -0.471; proposed, γ = -0.625). On adjusted analysis, all the staging systems had a significant correlation with DFS, while only AJCC-8E and the proposed staging correlated with CSS and OS. On ROC curve analysis, the proposed staging had the highest area under the curve and was the only staging system to statistically correlate with all the outcome variables. CONCLUSIONS: The proposed staging for pT2/pT3 tumour stages in penile cancer may improve the prognostic and predictive ability.

RESUMEN

BACKGROUND: Risk-reducing operations are an important part of the management of hereditary predisposition to cancer. In selected cases, they can considerably reduce the morbidity and mortality associated with cancer in this population. OBJECTIVES: The Brazilian Society of Surgical Oncology (BSSO) developed this guideline to establish national benchmarks for cancer risk-reducing operations. METHODS: The guideline was prepared from May to December 2021 by a multidisciplinary team of experts to discuss the surgical management of cancer predisposition syndromes. Eleven questions were defined and assigned to expert groups that reviewed the literature and drafted preliminary recommendations. Following a review by the coordinators and a second review by all participants, the groups made final adjustments, classified the level of evidence, and voted on the recommendations. RESULTS: For all questions including risk-reducing colectomy, gastrectomy, and thyroidectomy, a major agreement was achieved by the participants, always using accessible alternatives. CONCLUSION: This and its accompanying article represent the first guideline in cancer risk reduction surgery developed by the BSSO and it should serve as an important reference for the management of families with cancer predisposition.

RESUMEN

BACKGROUND AND OBJECTIVES: The primary treatment for locally advanced cases of cervical cancer is chemoradiation followed by high-dose brachytherapy. When this treatment fails, pelvic exenteration (PE) is an option in some cases. This study aimed to develop recommendations for the best management of patients with cervical cancer undergoing salvage PE. METHODS: A questionnaire was administered to all members of the Brazilian Society of Surgical Oncology. Of them, 68 surgeons participated in the study and were divided into 10 working groups. A literature review of studies retrieved from the National Library of Medicine database was carried out on topics chosen by the participants. These topics were indications for curative and palliative PE, preoperative and intraoperative evaluation of tumor resectability, access routes and surgical techniques, PE classification, urinary, vaginal, intestinal, and pelvic floor reconstructions, and postoperative follow-up. To define the level of evidence and strength of each recommendation, an adapted version of the Infectious Diseases Society of America Health Service rating system was used. RESULTS: Most conducts and management strategies reviewed were strongly recommended by the participants. CONCLUSIONS: Guidelines outlining strategies for PE in the treatment of persistent or relapsed cervical cancer were developed and are based on the best evidence available in the literature.

RESUMEN

BACKGROUND: To evaluate demographic, clinical and pathological characteristics of small renal masses (SRM) (≤ 4 cm) in a Latin-American population provided by LARCG (Latin-American Renal Cancer Group) and analyze predictors of survival, recurrence and metastasis. METHODS: A multi-institutional retrospective cohort study of 1523 patients submitted to surgical treatment for non-metastatic SRM from 1979 to 2016. Comparisons between radical (RN) or partial nephrectomy (PN) and young or elderly patients were performed. Kaplan-Meier curves and log-rank tests estimated 10-year overall survival. Predictors of local recurrence or metastasis were analyzed by a multivariable logistic regression model. RESULTS: PN and RN were performed in 897 (66%) and 461 (34%) patients. A proportional increase of PN cases from 48.5% (1979-2009) to 75% (after 2009) was evidenced. Stratifying by age, elderly patients (≥ 65 years) had better 10-year OS rates when submitted to PN (83.5%), than RN (54.5%), p = 0.044. This disparity was not evidenced in younger patients. On multivariable model, bilaterality, extracapsular extension and ASA (American Society of Anesthesiologists) classification ≥3 were predictors of local recurrence. We did not identify significant predictors for distant metastasis in our series. CONCLUSIONS: PN is performed in Latin-America in a similar proportion to developed areas and it has been increasing in the last years. Even in elderly individuals, if good functional status, sufficiently fit to surgery, and favorable tumor characteristics, they should be encouraged to perform PN. Intending to an earlier diagnosis of recurrence or distant metastasis, SRM cases with unfavorable characteristics should have a more rigorous follow-up routine.

RESUMEN

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.

RESUMEN

PURPOSE: The SLC8A1 gene, which encodes the Na(+)/Ca(2+) exchanger, has a key role in calcium homeostasis. Our previous gene expression oligoarray data revealed SLC8A1 under expression in penile carcinoma. We investigated whether dysregulation of SLC8A1 expression is associated with apoptosis and cell proliferation in penile carcinoma via modulation of the calcium concentration. The underlying mechanisms of SLC8A1 under expression were also explored, focusing on copy number alteration and miRNA. MATERIALS AND METHODS: Transcript levels of the SLC8A1 gene and miR-223 were evaluated by quantitative polymerase chain reaction to compare penile carcinoma samples with normal glans tissue. SLC8A1 copy number was evaluated by microarray based comparative genomic hybridization. In normal and tumor samples we investigated caspase-3 and Ki-67 immunostaining as well as calcium distribution by laser ablation imaging inductively coupled plasma mass spectrometry. RESULTS: SLC8A1 under expression was detected in penile carcinoma samples (p = 0.001), confirming our previous data. It was not associated with gene copy number loss. In contrast, miR-223 over expression (p = 0.002) inversely correlated with its putative repressor SLC8A1 (r = -0.426, p = 0.015). SLC8A1 under expression was associated with decreased calcium distribution, high Ki-67 and low caspase-3 immunoexpression in penile carcinoma compared to normal tissue. CONCLUSIONS: Down-regulation of the SLC8A1 gene, most likely mediated by its regulator miR-223, can lead to decreased calcium in penile carcinoma and consequently to suppressed apoptosis and increased tumor cell proliferation. These data suggest that the miR-223-NCX1-calcium signaling axis may represent a potential therapeutic approach to penile carcinoma.

RESUMEN

BACKGROUND: Superoxide dismutase-2 (SOD2) is considered one of the most important antioxidant enzymes that regulate cellular redox state in normal and tumorigenic cells. Overexpression of this enzyme in lung, gastric, colorectal, breast cancer and cervical cancer malignant tumors has been observed. Its relationship with inguinal lymph node metastasis in penile cancer is unknown. METHODS: SOD2 protein expression levels were determined by immunohistochemistry in 125 usual type squamous cell carcinomas of the penis from a Brazilian cancer center. The casuistic has been characterized by means of descriptive statistics. An exploratory logistic regression has been proposed to evaluate the independent predictive factors of lymph node metastasis. RESULTS: SOD2 expression in more than 50% of cells was observed in 44.8% of primary penile carcinomas of the usual type. This expression pattern was associated with lymph node metastasis both in the uni and multivariate analysis. CONCLUSIONS: Our results indicate that SOD2 expression predicts regional lymph node metastasis. The potential clinical implication of this observation warrants further studies.

RESUMEN

OBJECTIVE: To analyse the immunohistochemical and mRNA expression of SWI/SNF (SWItch/Sucrose NonFermentable) complex subunit polybromo-1 (PBRM1) in clear cell renal cell carcinoma (ccRCC) and its impact on clinical outcomes. PATIENTS AND METHODS: In all, 213 consecutive patients treated surgically for renal cell carcinoma (RCC) between 1992 and 2009 were selected. A single pathologist reviewed all cases to effect a uniform reclassification and determined the most representative tumour areas for construction of a tissue microarray. In addition, mRNA expression of PBRM1 was analysed by reverse transcriptase-polymerase chain reaction. RESULTS: Of the 112-immunostained ccRCC specimens, 34 (30.4%) were PBRM1-negative, and 78 (69.6%) were PBRM1-positive. The protein expression of PBRM1 was associated with tumour stage (P < 0.001), clinical stage (P < 0.001), pN stage (P = 0.035) and tumour size (P = 0.002). PBRM1 mRNA expression was associated with clinical stage (P = 0.023), perinephric fat invasion (P = 0.008) and lymphovascular invasion (P = 0.042). PBRM1 significantly influenced tumour recurrence and tumour-related death. Disease-specific survival rates for patients whose specimens showed positive- and negative-PBRM1 expression were 89.7% and 70.6%, respectively (P = 0.017). Recurrence-free survival rates in patients with positive- and negative-expression of PBRM1 were 87.3% and 66.7%, respectively (P = 0.048). CONCLUSIONS: PBRM1-negative expression is a markedly poor prognosis event in ccRCC. We encourage PBRM1 study by other groups in order to validate our findings and confirm its possible role as a useful marker in the management of patients with ccRCC.

RESUMEN

PURPOSE: To evaluate the immunohistochemical expression of nitric oxide synthase (NOS) types 1, 2, and 3 in intratumoral and non-neoplastic samples of renal cell carcinoma (RCC) and correlate it with the clinical and pathological features of this malignancy. METHODS: We analyzed 110 patients with RCC underwent radical nephrectomy (RN) or partial nephrectomy (PN) by streptavidin-biotin peroxidase method, tissue microarray, and digital microscopy. As endpoints, NOS expression was correlated with pathological features, overall survival (OS), and cancer-specific survival (CSS). RESULTS: Non-neoplastic samples had higher NOS3 and lower NOS 2 levels than RCC tissues. Greater expression of all NOS isoforms was associated with larger tumors. High NOS1 expression correlated with microscopic venous invasion (MVI) (p = 0.046) and lymph node metastases (p = 0.007). High NOS2 expression was linked to MVI, more RN performed, and male gender (p = 0.035, p = 0.003, and p = 0.027, respectively). High NOS3 expression correlated with lymph node metastases (p = 0.039), microlymphatic invasion (p = 0.029), invasion of the renal pelvis and ureter (p = 0.004), RN (p = 0.003), and shorter OS (58.1 vs. 79.4 % respectively, p = 0.033) by univariate analysis. DFS was not influenced by any NOS isoform. By multivariate analysis, the risk factors for death were TNM stages III and IV (hazard ratio [HR] = 4.5), high Fuhrman's grade (HR = 2.9), Karnofsky performance status ≤80 (HR = 2.5), progression (HR = 5.5), and recurrence (HR = 6.3). Stage III disease was an independent risk factor for recurrence (HR = 9.5). CONCLUSIONS: High NOS expression in RCC is associated with a poor prognosis and larger tumors. NOS3 influences OS by univariate analysis.

RESUMEN

Over the past 20 years, the field of robotic surgery has largely been dominated by the da Vinci robotic platform. Nevertheless, numerous novel multiport robotic surgical systems have been developed over the past decade, and some have recently been introduced into clinical practice. This nonsystematic review aims to describe novel surgical robotic systems, their individual designs, and their reported uses and clinical outcomes within the field of urologic surgery. Specifically, we performed a comprehensive review of the literature regarding the use of the Senhance robotic system, the CMR-Versius robotic system, and the Hugo RAS in urologic procedures. Systems with fewer published uses are also described, including the Avatera, Hintori, and Dexter. Notable features of each system are compared, with a particular emphasis on factors differentiating each system from the da Vinci robotic system.

RESUMEN

What's known on the subject? and What does the study add? Bilateral testicular germ cell tumours (BTGCTs) are rare neoplasms. Most previously published studies consist of case reports or small retrospective case series. Little is known about their epidemiological and clinicopathological characteristics. BTGCT corresponded to 1.82% of testicular tumours. Metachronous disease was about twice as frequent as synchronous disease. The primary tumour histology, chemotherapy use and the interval between metachronous tumours influenced the histology of the second tumour. Overall, synchronous tumours were associated with more advanced disease and presented less favourable survival rates than metachronous tumours. Testicular cancer is the most common tumour in young men. It is known that a second primary contralateral testis tumour may occur in up to 5% of men with a proior tumour. About 35% of these men present with synchronous tumours, and 65% present with metachronous tumours. However there is little data about bilateral testicular germ cell tumours (BTGCT) in the literature and the most published articles are case reports on a small series of men, which makes it difficult to draw conclusions about therapeutic strategies for the treatment of BTGCTs. In fact, current guidelines for the treatment of testicular cancer contain little information related to bilateral disease. Therefore, the aim of our study is to provide a broad overview of BTGCT and to update data focusing on incidence, pathological features, and clinical outcomes of men with BTGCTs. Thus, an extensive review containing 94 studies and more than 50,000 patients was conducted.

RESUMEN

OBJECTIVES: We analyzed whether the American Society of Anesthesiology (ASA) classification could be used as a prognostic factor in renal cell carcinoma. METHODS: ASA classification's impact on cancer-specific survival (CSS) and on overall survival in 145 patients submitted to radical or partial nephrectomy was evaluated, and was compared with clinicopathological variables. RESULTS: CSS was influenced by ASA in uni- and multivariate analyses. Five-year CSS was 95.7, 71.1 and 39.8% for ASA 1, ASA 2 and ASA 3, respectively (p = 0.007). The ASA classification influenced the overall survival too (p < 0.001). When 18 patients with metastases were excluded, the CSS was 95.7, 83.9 and 42.9% for ASA 1, ASA 2 and ASA 3, respectively (p = 0.001). ASA 3 patients had ten times more metastases than ASA1 patients and two times more than ASA 2 patients (p = 0.001). ASA 3 patients had fewer incidental tumors (p = 0.043) than ASA 2 and 3 patients. CONCLUSION: In this series, the ASA classification could be used as a prognostic factor in renal cell carcinoma.

RESUMEN

PURPOSE: Investigate ErbB family expression in colorectal cancer patients with higher risk of recurrence after surgical treatment. METHODS: We studied 109 individuals with high risk stage II and stage III patients submitted to radical surgery. ErbB expression was assessed by tissue microarray technique. RESULTS: The immunohistochemical expression was considered positive for EGFR, ErbB2, ErbB3, ErbB4 membrane, and ErbB4 cytoplasmic in respectively 57.8%, 8.3%, 69.7%, 11%, and 19.3% of patients. ErbB3 negative expression was associated with lymphovascular invasion. EGFR, ErbB2, and cytoplasmic ErbB4 expression was not associated with prognosis. Membranous positive ErbB4 expression was an independent prognostic factor for recurrence. ErbB3 negative expression was an independent prognostic factor for recurrence and survival in the multivariate analysis. CONCLUSIONS: The immunohistochemical expression of ErbB3 and ErbB4 may identify a subgroup with stage II and III colorectal cancer at higher risk of recurrence.

RESUMEN

OBJECTIVES: To determine the incidence of suicide risk in a group of patients who have been diagnosed with localized prostate cancer (PC) and to identify the factors that affect suicidal behavior. METHODS: Patients from a tertiary care oncology center in São Paulo, Brazil participated in this study and were interviewed after being diagnosed with low-risk or intermediate-risk PC, per the D'Amico risk classification, between September 2015 and March 2016. Patients underwent suicide risk assessment sessions using the Mini International Neuropsychiatric Interview (MINI), the Hospital Anxiety and Depression Scale (HADS), and the CAGE substance abuse screening tool before they started treatment and surveillance. Psychiatric treatment history, family history of suicidal behavior, and the use of psychotropic drugs were also examined. RESULTS: The prevalence of suicide risk among 250 patients who were recently diagnosed with low-risk or intermediate-risk PC was 4.8%. According to the HADS, 10.8% and 6.8% of patients had a positive score anxiety and for depression, respectively. Alcoholism was suspected in 2.8% of the group. Suicide risk was associated with anxiety (p=0.001); depression (p=0.005); being divorced, separated, widowed, or single (p=0.045); living alone (p=0.028); and prior psychological treatment (p=0.003). CONCLUSIONS: After being diagnosed with PC, patients who display risk factors for suicide should be monitored by a mental health team.

RESUMEN

Penile carcinoma (PeCa) is an important public health issue in poor and developing countries, and has only recently been explored in terms of genetic and epigenetic studies. Integrative data analysis is a powerful method for the identification of molecular drivers involved in cancer development and progression. miRNA and mRNA expression profiles followed by integrative analysis were investigated in 23 PeCa and 12 non-neoplastic penile tissues (NPT). Expression levels of eight miRNAs and 10 mRNAs were evaluated in the same set of samples used for microarray and in a validation set of cases (PeCa = 36; NPT = 27). Eighty-one miRNAs and 2,697 mRNAs were identified as differentially expressed in PeCa. Integrative data analysis revealed 255 mRNAs potentially regulated by 68 miRNAs. Using RT-qPCR, eight miRNAs and nine transcripts were confirmed as altered in PeCa. We identified that MMP1, MMP12 and PPARG and hsa-miR-31-5p, hsa-miR-224-5p, and hsa-miR-223-3p were able to distinguish tumors from NPT with high sensitivity and specificity. Higher MMP1 expression was detected as a better predictor of lymph node metastasis than the clinical-pathological data. In addition, PPARG and EGFR were highlighted as potential pathways for targeted therapy in PeCa. The analysis based on HPV positivity (7 of 23 cases) revealed five miRNA and 13 mRNA differentially expressed. Although in a limited number of cases, HPV positive PeCa presented less aggressive phenotype in comparison with negative cases. Overall, an integrative analysis using mRNA and miRNA profiles revealed markers related with tumor development and progression. Furthermore, MMP1 expression level was a predictive marker for lymph node metastasis in patients with PeCa.

RESUMEN

OBJECTIVE: Ulceration is common in bladder tumors, but its prognostic role, although intuitive, is not established. We aim to explore the presence of gross ulceration and its relationship with other morphological and biological features classically associated with extravesical disease, in patients submitted to radical cystectomy. METHODS: Tumor size and morphology were noted on 101 cystectomy patients (2000-2010). Papillary, exophytic, and vegetant tumors were grouped as "papillary" and solid/nodular, ulcerated and infiltrative as "nonpapillary." Ulceration was noted grossly in every case as a binary parameter, regardless of morphology. Immunohistochemistry was performed for hypoxia (hypoxia-inducible factor-1α and vascular endothelial growth factor), and cell cycle proteins (pRb, p53, and cyclin D1). RESULTS: Mean age was 66.7 year, male:female ratio was 2:1, 20 patients received bacillus Calmette-Guerin and 10 neoadjuvant chemotherapy. Upstaging rate was 56.4%. Ulcerated lesions presented mostly as nonpapillary and nonorgan confined (nOC), whereas nonulcerated tumors were often papillary and organ confined (OC). Tumor size was smaller in nonpapillary tumors (P = 0.002), but did not associate with altered hypoxia or cell cycle expressions. pRb and cyclin D1 loss and p53 overexpression were more frequent in ulcerated and non-OC tumors as did the phenotype vascular endothelial growth factor-negative/hypoxia-inducible factor-1α-low (P<0.001). On a multivariate model, ulceration was an independent predictor of non-OC and extravesical disease. CONCLUSION: Patients with ulcerated tumors were often staged with extravesical disease, independent of other morphologic and biological features known to affect prognosis. Prospective studies are needed to confirm the predictive value of tumor ulceration at cystoscopy, which could improve patient stratification for neoadjuvant chemotherapy.

RESUMEN

The molecular mechanisms underlying penile carcinoma are still poorly understood, and the detection of genetic markers would be of great benefit for these patients. In this study, we assessed the genomic profile aiming at identifying potential prognostic biomarkers in penile carcinoma. Globally, 46 penile carcinoma samples were considered to evaluate DNA copy-number alterations via array comparative genomic hybridization (aCGH) combined with human papillomavirus (HPV) genotyping. Specific genes were investigated by using qPCR, FISH, and RT-qPCR. Genomic alterations mapped at 3p and 8p were related to worse prognostic features, including advanced T and clinical stage, recurrence and death from the disease. Losses of 3p21.1-p14.3 and gains of 3q25.31-q29 were associated with reduced cancer-specific and disease-free survival. Genomic alterations detected for chromosome 3 (LAMP3, PPARG, TNFSF10 genes) and 8 (DLC1) were evaluated by qPCR. DLC1 and PPARG losses were associated with poor prognosis characteristics. Losses of DLC1 were an independent risk factor for recurrence on multivariate analysis. The gene-expression analysis showed downexpression of DLC1 and PPARG and overexpression of LAMP3 and TNFSF10 genes. Chromosome Y losses and MYC gene (8q24) gains were confirmed by FISH. HPV infection was detected in 34.8% of the samples, and 19 differential genomic regions were obtained related to viral status. At first time, we described recurrent copy-number alterations and its potential prognostic value in penile carcinomas. We also showed a specific genomic profile according to HPV infection, supporting the hypothesis that penile tumors present distinct etiologies according to virus status.

RESUMEN

Disease recurrence occurs frequently after surgical treatment for squamous cell carcinoma of the penis (SCCp). We sought to determine prognostic factors that influence cancer-specific mortality (CSM) after disease recurrence in patients with SCCp. We performed a retrospective analysis of 314 patients who experienced disease recurrence after surgical treatment for SCCp between 1949 and 2012. Competing risk regression analysis addressed factors associated with CSM after SCCp recurrence. Median time from surgery to disease recurrence was 10.5 mo (interquartile range [IQR]: 5.9-21.3). Of the recurrences, 165 (53%), 118 (38%), and 31 (9.9%) were local, regional, or distant, respectively. Within a median follow-up of 4.5 yr (IQR: 2.0-6.5), 108 patients died of SCCp and 41 patients died of causes other than SCCp. Shorter time to disease recurrence was found to be significantly associated with a higher risk of CSM (p=0.0006). Lymph node metastasis at the time of initial treatment (subdistribution hazard ratio [SHR]: 1.96; 95% confidence interval [CI] 1.23- 3.11; p=0.005) and regional recurrence (SHR: 4.14; 95% CI, 2.16-7.93; p<0.0001) or distant recurrence (SHR: 5.75; 95% CI, 2.59-12.73; p<0.0001) were associated with increased risk of CSM after disease recurrence. Inclusion of time to recurrence into risk stratification may help patient counseling and treatment planning.

RESUMEN

OBJECTIVES: To determine the incidence of suicide risk in a group of patients who have been diagnosed with localized prostate cancer (PC) and to identify the factors that affect suicidal behavior. METHODS: Patients from a tertiary care oncology center in São Paulo, Brazil participated in this study and were interviewed after being diagnosed with low-risk or intermediate-risk PC, per the D'Amico risk classification, between September 2015 and March 2016. Patients underwent suicide risk assessment sessions using the Mini International Neuropsychiatric Interview (MINI), the Hospital Anxiety and Depression Scale (HADS), and the CAGE substance abuse screening tool before they started treatment and surveillance. Psychiatric treatment history, family history of suicidal behavior, and the use of psychotropic drugs were also examined. RESULTS: The prevalence of suicide risk among 250 patients who were recently diagnosed with low-risk or intermediate-risk PC was 4.8%. According to the HADS, 10.8% and 6.8% of patients had a positive score anxiety and for depression, respectively. Alcoholism was suspected in 2.8% of the group. Suicide risk was associated with anxiety (p=0.001); depression (p=0.005); being divorced, separated, widowed, or single (p=0.045); living alone (p=0.028); and prior psychological treatment (p=0.003). CONCLUSIONS: After being diagnosed with PC, patients who display risk factors for suicide should be monitored by a mental health team.

RESUMEN

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.
