Prognostic Impact of Preoperative Thrombocytosis on Recurrence-Free Survival in Patients with Upper Tract Urothelial Carcinoma.

BACKGROUND: The aim of this work was to evaluate the prognostic potential of preoperative thrombocytosis for recurrence-free survival (RFS) and cancer-specific survival (CSS) among patients subjected to radical nephroureterectomy (RNU) due to UTUC. PATIENTS AND METHODS: Analytical cohort was composed of a single-center series of 405 patients treated between January 1999 and December 2020. Thrombocytosis was defined as a platelet count exceeding the threshold value of 400 × 109 per L. Along with the Kaplan-Meier survival probability, Cox proportional hazard regression models were used. RESULTS: Preoperative thrombocytosis confirmed in 71 patients (17.5%) was significantly associated with the higher pathological tumor stage, lymph node metastasis, prior bladder cancer diagnosis, and preoperative anemia. With a median post-surgical follow-up period of 33.5 months, 125 patients (30.9%) experienced disease recurrence. The recurrence rate among patients with normal platelet levels was 13.6%, compared with 22.2% in those with preoperative thrombocytosis (p < 0.03). The 5-year RFS estimates reached 36.6% in the thrombocytosis-confirmed group. Multivariate analysis implied that preoperative thrombocytosis was a significant independent prognosticator of both poor RFS (HR 2.22, 95% CI 1.14-4.31, p = 0.02) and CSS (HR 2.48, 95% CI 1.14-3.09, p = 0.01). CONCLUSIONS: Patients with a clinically significant elevation of platelet count prior to RNU were more likely to have UTUC with advanced tumor stages and lymph node metastases. Preoperative thrombocytosis was an independent predictor of RFS and CSS in patients who underwent radical nephroureterectomy. Furthermore, preoperative thrombocytosis may complement and refine UTUC clinical prediction algorithms as an independent indicator of adverse survival outcomes.

Partial versus radical nephrectomy for pT1a renal cancer in Serbia.

PURPOSE: To assess the treatment outcome of pT1a renal tumors, comparing overall survival (OS) in patients treated with radical nephrectomy (RN) and partial nephrectomy (PN), and to examine the rate of utilization of PN in a tertiary institution in Serbia. METHODS: Included were patients treated for pT1a kidney tumors with open RN or open PN during 1996-2013. The inclusion criterion was the pathological tumor stage T1a. Exclusion criteria were higher pathological stages, metastatic presentation, or imperative indications for partial nephrectomy. Patients were followed-up every 3 to 4 months for the first year after surgery, every 6 months until the 5th year, and annually thereafter. RESULTS: 286 patients were included in the study, and PN was performed in 177 (61.9%) of them, whereas RN was performed in the remaining 109 (38.1%). The median follow- up for the entire group was 42.0 months (interquartile range 74.5). There were no statistically significant differences between groups in cancer-specific survival (CSS) (log-rank=0.506; p=0.477). Patients selected for RN were more likely to be older, symptomatic at presentation, and have larger tumors. There was no statistically significant difference in OS between the two groups (log-rank=2.616; p=0.106). In 1996, 20% of the patients were treated with PN; this number increased to 88% in 2013. CONCLUSION: We did not find OS advantage for PN compared to RN in the setting of a developing country. The use of PN is increasing and is now utilized for ∼90% of pT1a renal tumors.

Multifocality in Testicular Cancer: Clinicopathological Correlations and Prognostic Implications.

There are limited data regarding the significance of multifocality in testicular cancer patients. This study evaluated the relationship between multifocality and clinicopathological features determined at the time of radical orchiectomy. The study involved 280 consecutive patients who underwent radical orchiectomy between 2018 and 2023. Multifocality was defined as a distinct tumor focus characterized by a group of malignant cells > 1 mm, clearly differentiated from the primary tumor mass. Uni- and multivariate logistic regression analyses were employed to investigate the association between multifocality and histopathological parameters along with potential risk factors for clinical stages II + III. Multifocality was identified in 44 (15.7%) patients. Significantly smaller primary tumors were observed in subjects with multifocality (20.0 mm vs. 30.0 mm, p = 0.0001), while those exhibiting monofocality presented a markedly elevated rate of tumors exceeding 4 cm (40.3% vs. 18.2%, p = 0.005). Furthermore, multifocality was associated with a significantly higher rate of primary tumors < 2 cm (52.3% vs. 29.2%, p = 0.003). Univariate logistic regression analysis revealed a substantial decrease in the likelihood of multifocality occurrence in seminoma patients with tumors > 4 cm (OR = 0.38, p = 0.017). Meanwhile, in multivariate logistic regression, multifocality did not emerge as a significant risk factor for clinical stages II + III in either seminoma (p = 0.381) or non-seminoma (p = 0.672) cases. Our study suggests that multifocality holds no substantial prognostic relevance for clinically advanced disease in testicular cancer patients. The findings indicate that multifocality is associated with smaller primary tumors, particularly those measuring less than 2 cm.

Health-related quality of life, depression, and sexual function in testicular cancer survivors in a developing country: a Serbian experience.

PURPOSE: The aims of this study were to assess health-related quality of life (HRQoL), depression, adverse physical symptoms, and sexual function within Serbian long-term testicular cancer survivors (TCS) and to address cultural specificity. METHODS: This is a cross-sectional study involving 202 TCS, followed up after platinum-based chemotherapy. The HRQoL was measured using the Short Form 36 and the European Organization for Research and Treatment of Cancer Quality of Life questionnaire. The Beck Depression Inventory (BDI) was used to explore general depressive status while sexual function was assessed using a nine-item questionnaire. RESULTS: The mean follow-up time since treatment was 47.3 ± 26.8 months. The highest values of the SF-36 scales were obtained for physical functioning, and the lowest SF-36 values were obtained for vitality. Age of patients and BDI scores statistically significantly influenced total quality of life. The mean score of the whole sample on the BDI-II was 4.0. Age is the only statistically significant risk factor for the development of depression. A total of 27.3% TCS reported decreased sexual function compared to the period before treatment. Any level of impairment of erectile function was reported by 20.8% patients and problems with ejaculation by 25.7% patients. Loss of desire was reported by 17.3% TCS. The presence of sexual problems statistically significantly lowered scores of SF-36 domains. CONCLUSION: Sexual problems seriously impaired HRQoL in TCS. Additionally, HRQoL was also affected by age, depression, and fatigue. Serbian TCS achieved high levels of SF-36 scores, and these results are comparable to studies conducted in developed countries.

Prognostic Significance of Systemic Inflammation Markers in Testicular and Penile Cancer: A Narrative Review of Current Literature.

In contemporary clinical practice, biomarkers are indispensable in the assessment and management of oncological patients. Although established serum tumor markers (beta human chorionic gonadotropin (bHCG), alpha fetoprotein (AFP), and lactate dehydrogenase (LDH)) have an indisputably important role in the management of patients with testicular cancer (TC), the application of these tumor markers may be accompanied with certain limitations, implying the need for additional biomarkers. Contrary to TC, there is a lack of established serological biomarkers for penile cancer (PC) and the management of this urological malignancy is based on multiple clinicopathological parameters. Therefore, the identification and rigorous analytical and clinical validation of reliable biomarkers are considered pivotal for improving PC management. Inflammation may be associated with all stages of oncogenesis, from initial neoplastic transformation to angiogenesis, tissue invasion, and metastasis. Accordingly, an array of inflammation-related indices have gained increasing attention as emerging predictors of oncological outcomes. The clinical usefulness of systemic inflammation markers was reported in many urological and non-urological malignancies. The aim of this narrative review is to summarize current scientific data regarding the prognostic and predictive significance of systemic inflammation markers in TC and PC patients.

The Polymorphisms in GSTO Genes (GSTO1 rs4925, GSTO2 rs156697, and GSTO2 rs2297235) Affect the Risk for Testicular Germ Cell Tumor Development: A Pilot Study.

Members of the omega class of glutathione transferases (GSTs), GSTO1, and GSTO2, catalyze a range of reduction reactions as a part of the antioxidant defense system. Polymorphisms of genes encoding antioxidant proteins and the resultant altered redox profile have already been associated with the increased risk for testicular germ cell cancer (GCT) development. The aim of this pilot study was to assess the individual, combined, haplotype, and cumulative effect of GSTO1rs4925, GSTO2rs156697, and GSTO2rs2297235 polymorphisms with the risk for testicular GCT development, in 88 patients and 96 matched controls, through logistic regression models. We found that carriers of the GSTO1*C/A*C/C genotype exhibited an increased risk for testicular GCT development. Significant association with increased risk of testicular GCT was observed in carriers of GSTO2rs2297235*A/G*G/G genotype, and in carriers of combined GSTO2rs156697*A/G*G/G and GSTO2rs2297235*A/G*G/G genotypes. Haplotype H7 (GSTO1rs4925*C/GSTO2rs2297235*G/GSTO2rs156697*G) exhibited higher risk of testicular GCT, however, without significant association (p > 0.05). Finally, 51% of testicular GCT patients were the carriers of all three risk-associated genotypes, with 2.5-fold increased cumulative risk. In conclusion, the results of this pilot study suggest that GSTO polymorphisms might affect the protective antioxidant activity of GSTO isoenzymes, therefore predisposing susceptible individuals toward higher risk for testicular GCT development.

The Polymorphisms of Genes Encoding Catalytic Antioxidant Proteins Modulate the Susceptibility and Progression of Testicular Germ Cell Tumor.

The simultaneous analysis of redox biomarkers and polymorphisms encoding for regulatory and catalytic antioxidant proteins was performed in order to evaluate their potential role in the development of testicular germ cell tumor (GCT), as well as the progression of the disease. NRF2 (rs6721961), GSTM3 (rs1332018), SOD2 (rs4880) and GPX3 (rs8177412) polymorphisms were assessed in 88 patients with testicular GCT (52 with seminoma) and 88 age-matched controls. The plasma levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), thiol groups and the plasma activity of glutathione peroxidase were measured. A significant association between variant GPX3*TC+CC genotype and risk of overall testicular GCT, as well as seminoma development, was found. Moreover, carriers of variant SOD2*TT genotype were at almost 3-fold increased risk of seminoma development. Interestingly, combined SOD2*TT/GPX3*TC+CC genotype conferred a 7-fold higher risk for testicular GCT development. Finally, variant GSTM3*AC+CC genotype was associated with a higher risk for the development of advanced diseased. The presence of assessed genetic variants was not associated with significantly higher levels of redox biomarkers in both testicular GCT patients, as well as in those diagnosed with seminoma. In conclusion, the polymorphic expression of certain antioxidant enzymes might affect susceptibility toward testicular GCT development, as well as the progression of the disease.

Interplay between Comprehensive Inflammation Indices and Redox Biomarkers in Testicular Germ-Cell Tumors.

Sustained and dysregulated inflammation, concurrent tumor-induced immune suppression, and oxidative stress are profoundly involved in cancer initiation, presentation, and perpetuation. Within this prospective study, we simultaneously analyzed the preoperative indices of systemic inflammatory response and the representative byproducts of oxidative DNA, protein, and lipid damage with the aim of evaluating their clinical relevance among patients diagnosed with testicular germ-cell tumors (GCT). In the analytical cohort (n = 88, median age 34 years), neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and C-reactive protein (CRP) were significantly altered in patients with a higher tumor stage (p < 0.05). Highly suggestive correlations were found between NLR, dNLR, and SII and modified nucleoside 8-OHdG. CRP and albumin-to-globulin ratio (AGR) significantly correlated with thiols group level and maximal tumor dimension (p < 0.05). Based on receiver operating characteristic (ROC) curve analyses, all the evaluated pre-orchiectomy inflammation markers demonstrated strong performance in predicting metastatic disease; optimal cut-off points were determined for each indicator. Although further large-scale studies are warranted, inflammatory and redox indices may both complement the established tumor markers and standard clinicopathological prognostic variables and contribute to enhanced personalized risk-assessment among testicular GCT patients.

Renal cancer and Wegener's granulomatosis: a case report.

Wegener's granulomatosis (WG) is a systemic disorder characterized by necrotizing vasculitis involving the respiratory tract, and in most cases, the kidneys. The most common manifestation of WG in the kidneys is segmental necrotizing glomerulonephritis. The presence of a renal mass as a manifestation of WG is rare. We report a patient with WG in whom a CT scan revealed an infiltrating mass in the lower portion of the left kidney. After surgical exploration, we performed an open radical nephrectomy. Histopathology showed clear cell type renal cell carcinoma (RCC). RCC associated with WG has been reported in only a few cases, and in most of them, the diseases started simultaneously, suggesting common pathogenetic pathways. Long-term immunosuppressive treatment is a known risk factor in the development of malignancies, so occurrence of RCC in WG has been proposed as a side effect of cyclophosphamide treatment. Furthermore, it is important to make a differential diagnosis between RCC and pseudotumors in WG as they cannot be distinguished solely on basis of imaging findings. Due to the higher risk of urologic malignancies, more frequent checkups and screening of WG patients should be considered.

Prognostic value of Balkan endemic nephropathy and gender on upper tract urothelial carcinoma outcomes after radical nephroureterectomy: A cohort study.

BACKGROUND: To identify the prognostic impact of residence in a BEN-endemic area and gender on upper tract urothelial carcinoma (UTUC) outcomes in Serbian patients treated with radical nephroureterectomy (RNU). METHODS: The study included 334 consecutive patients with UTUC. Patients with permanent residence in Balkan endemic nephropathy (BEN) or non-endemic areas from their birth to the end of follow-up were included in the analysis. Cox regression analyses were used to address recurrence-free (RFS) and cancer-specific survival (CSS) estimates. RESULTS: Female patients were more likely to have preoperative pyuria (P = 0.01), tumor multifocality was significantly associated with the female gender (P = 0.003). Gender was not associated with pathologic stage and grade, lymph node metastasis, lymphovascular invasion, adjuvant chemotherapy, bladder cancer history, tumor size, distribution of tumor location, preoperative anemia and demographic characteristics. A total of 107 cases recurred, with a median time to bladder recurrence of 24.5 months. History of bladder tumor (HR, 1.98; P = 0.005), tumor multifocality (HR, 3.80; P < 0.001) and residence in a BEN-endemic area (HR, 1.81; P = 0.01) were independently associated with bladder cancer recurrence. The 5-year bladder cancer RFS for the patients from areas of BEN was 77.8 % and for the patients from non-BEN areas was 64.7 %. The 5-year CSS for the men was 66.2% when compared to 66.6% for the women (P = 0.55). CONCLUSIONS: Residence in a BEN-endemic area represents an independent predictor of bladder cancer recurrence in patients who underwent RNU. Gender cannot be used to predict outcomes in a single-centre series of consecutive patients who were treated with RNU for UTUC.

Urothelial carcinoma of the upper urinary tract: preoperative pyuria is not correlated with bladder cancer recurrence and survival.

OBJECTIVE: To identify the impact of preoperative pyuria on the bladder cancer recurrence and survival of patients who were treated surgically for UTUC. PATIENTS AND METHODS: Study included 319 consecutive patients who were treated with RNU for UTUC. Cox proportional hazard regression models were used to evaluate the association of preoperative pyuria with outcome. RESULTS: Eighty patients (25.1%) had pyuria. Preoperative pyuria was associated with sex (P = 0.01), tumor focality (P = 0.01), tumor size (P = 0.05), tumor stage (P = 0.01), lymph node metastasis (P = 0.01), lymphovascular invasion (P = 0.02), and chemotherapy (P = 0.04). A total of 102 patients recurred, with a median time to bladder recurrence of 24.2 months. Bladder cancer recurrence-free survival rates for these 319 patients at 1, 3, 5, 7, and 10 years were 84.6, 72.4, 69.0, 68.3, and 68.0%, respectively. Preoperative pyuria was not independently associated with bladder cancer recurrence (HR 1.15; p = 0.5). Preoperative pyuria was associated with OS (HR 1.57; p = 0.02) and CSS (HR 1.65; p = 0.02). However, preoperative pyuria was not independently associated with OS and CSS (HR 1.07; p = 0.79). CONCLUSIONS: Preoperative pyuria is unable to predict outcomes in a single-centre series of consecutive patients who were treated with RNU.

Isolated eyeball metastasis of non-seminomatous germ cell testicular tumor.

INTRODUCTION: Testicular tumors most frequently metastasize to regional lymph nodes. Non-seminomatous tumor metastasis of testicle (NSGCTT) to the eyeball is rare. CASE REPORT: We presented a 24-year old man, referred to the ophthalmologist due to acute pain and abrupt loss of sight in the left eye accompanied by its enlargement. Orbital and endocranial computerized tomography (CT) was carried out, indicating the tumor in the left eye. His previous medical history provided the information that the right testicle was painlessly enlarged for 8 months. Ultrasonography showed a completely tumorously altered testis. Abdominal and chest CT failed to reveal any secondary deposits in visceral organs and lymph glands. Tumor markers (AFP - alpha-fetoproteins, beta hCG - human choronic gonadotropin beta) were elevated. Right radical orchiactomy was performed (showed NSGCTT), followed by polychemotherapy with cisplatinum 100 mg/m2, etoposide 120 mg/m2, bleomycin 15 mg/m2 (PEB x 4), resulting in normalization of tumor marker values and significant regression of the left eyeball. Next, the left eye enucleation and ocular prosthesis implantation was carried out. Pathohistological evaluation indicated fibrosis and necrosis only. In a 5-year follow-up period, the patient was free of recurrence. CONCLUSION: Isolated hematogenous metastasis of the NSGCTT to the eye is rare. In our case, the left eye was the only metastatic localization. After chemotherapy and eye enucleation the patient was in a 4-year follow-up period free of the recurrence.
