Unmarried Status Effect on Stage at Presentation and Treatment Patterns in Non-Metastatic Upper Tract Urothelial Carcinoma Patients. Clin Genitourin Cancer 2024; 22:102105. [PMID: 38759336 DOI: 10.1016/j.clgc.2024.102105] [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: 02/26/2024] [Revised: 04/21/2024] [Accepted: 04/22/2024] [Indexed: 05/19/2024]
Abstract
BACKGROUND Unmarried status has been associated with higher proportions of locally advanced stage and lower treatment dose intensification rates in several urological and non-urological malignancies. However, no previous investigators focused on the association between unmarried status and advanced stage (T3-4N0-2) at presentation and lower nephroureterectomy (RNU) and systemic therapy (ST) rates in non-metastatic upper tract urothelial carcinoma (UTUC) patients. METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020, all non-metastatic UTUC patients were identified. Multivariable logistic regression models (LRMs) tested for differences in stage at presentation and treatment (RNU and ST) according to marital status (married vs unmarried), in a sex-specific fashion. RESULTS Of all 8544 non-metastatic UTUC patients, 4748 (56%) were male vs 3190 (44%) were female. Of all 4748 male UTUC patients, 1191 (25%) were unmarried. Of all 3190 female UTUC patients, 1608 (50%) were unmarried. In multivariable LRMs predicting RNU, unmarried status was an independent predictor of lower RNU rates in male (Odds Ratio [OR]: 0.56; P < .001), but not in female (OR: 0.81; P = .1) non-metastatic UTUC patients. In multivariable LRMs predicting ST exposure, unmarried status was an independent predictor of lower ST rates in both male (OR:0.73; P = .03) and female (OR:0.64; P < .001) UTUC patients. In multivariable LRMs predicting locally advanced stage (T3-4N0-2), unmarried status was not associated with an increased risk of locally advanced stage at presentation in either male (OR: 0.95; P = .5) or female (OR: 0.99; P = .9) UTUC patients. CONCLUSIONS Unmarried male UTUC patients appear at risk of less being able to access RNU, relative to their married counterparts. Moreover, unmarried UTUC patients appear to less benefit from ST, regardless of sex. Conversely, unmarried status was not associated with an increased risk of locally advanced stage at presentation in either male or female UTUC patients.

Increased Apolipoprotein A1 Expression Correlates with Tumor-Associated Neutrophils and T Lymphocytes in Upper Tract Urothelial Carcinoma. Curr Issues Mol Biol 2024; 46:2155-2165. [PMID: 38534755 DOI: 10.3390/cimb46030139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 03/01/2024] [Accepted: 03/05/2024] [Indexed: 03/28/2024] Open
Abstract
An increased neutrophil-to-lymphocyte ratio (NLR) is a poor prognostic biomarker in various types of cancer, because it reflects the inhibition of lymphocytes in the circulation and tumors. In urologic cancers, upper tract urothelial carcinoma (UTUC) is known for its aggressive features and lack of T cell infiltration; however, the association between neutrophils and suppressed T lymphocytes in UTUC is largely unknown. In this study, we examined the relationship between UTUC-derived factors and tumor-associated neutrophils or T lymphocytes. The culture supernatant from UTUC tumor tissue modulated neutrophils to inhibit T cell proliferation. Among the dominant factors secreted by UTUC tumor tissue, apolipoprotein A1 (Apo-A1) exhibited a positive correlation with NLR. Moreover, tumor-infiltrating neutrophils were inversely correlated with tumor-infiltrating T cells. Elevated Apo-A1 levels in UTUC were also inversely associated with the population of tumor-infiltrating T cells. Our findings indicate that elevated Apo-A1 expression in UTUC correlates with tumor-associated neutrophils and T cells. This suggests a potential immunomodulatory effect on neutrophils and T cells within the tumor microenvironment, which may represent therapeutic targets for UTUC treatment.

Abstract
Background Upper tract urothelial carcinoma (UTUC) is a rare clinical condition primarily characterized by symptoms such as gross or microscopic hematuria, flank pain, and renal colic. Although computed tomography urography (CTU) is currently the most accurate imaging modality for diagnosis, atypical presentations and physical examination findings can sometimes obscure lesions, posing diagnostic challenges. Case presentation In this report, three patients exhibited atypical symptoms, sharing a common complaint of flank pain. Notably, the first patient, who had recently undergone laparoscopic right duplex nephrectomy, presented with microscopic hematuria, whereas the other two did not show any gross or microscopic hematuria. Computed tomography urography revealed hydronephrosis and infection without significant renal pelvic space-occupying lesions, with persistently elevated white blood cell (WBC) counts, but no fever. These atypical clinical presentations confounded clinicians, delaying the diagnosis of upper tract urothelial carcinoma until postoperative pathological examination for the first two patients and resulting in advanced-stage diagnosis for the third patient. Postoperative pathology confirmed high-grade invasive upper tract urothelial carcinoma in all three patients. Conclusion Upper tract urothelial carcinoma can manifest atypically without hematuria and may be challenging to visualize on computed tomography urography, potentially leading to misdiagnosis. Therefore, clinicians should maintain a high level of suspicion for malignant tumors when patients exhibit hydronephrosis, infection on imaging, and persistently elevated white blood cell counts without fever, even in the absence of typical signs of upper urothelial carcinoma on computed tomography urography.

[PMID: 37763728 PMCID: PMC10533139 DOI: 10.3390/medicina59091609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 09/02/2023] [Accepted: 09/05/2023] [Indexed: 09/29/2023]
Abstract
Background and Objectives: This study aimed to evaluate the diagnostic roles of various immunohistochemical (IHC) markers in urothelial carcinoma in situ (uCIS) through a meta-analysis and review of diagnostic test accuracy. Materials and Methods: The IHC markers CK20, CD44, AMACR, and p53 were evaluated in the present study. We analyzed the expression rates of the IHC markers and compared their diagnostic accuracies. Results: The estimated expression rates were 0.803 (95% confidence interval [CI]: 0.726-0.862), 0.142 (95% CI: 0.033-0.449), 0.824 (95% CI: 0.720-0.895), and 0.600 (95% CI: 0.510-0.683) for CK20, CD44, AMACR, and p53, respectively. In the comparison between uCIS and reactive/normal urothelium, the expression of CK20, AMACR, and p53 in uCIS was significantly higher than in reactive/normal urothelium. CD44 showed significantly lower expression in uCIS than in the reactive/normal urothelium. Among the markers, AMACR had the highest sensitivity, specificity, and diagnostic odds ratio. The AUC on SROC was the highest for CK20. Conclusions: In conclusion, IHC markers, such as CK20, CD44, AMACR, and p53, can be useful in differentiating uCIS from reactive/normal urothelium.

Abstract
BACKGROUND The debate on whether to choose a transperitoneal (TP) or retroperitoneal (RP) approach for treating upper urinary tract urothelial carcinoma (UTUC) with laparoscopic surgery has been drawing attention. This study aimed to systematically review and meta-analyze the existing evidence regarding oncologic and perioperative outcomes of transperitoneal laparoscopic radical nephroureterectomy (TLNU) and retroperitoneal laparoscopic radical nephroureterectomy (RLNU) in managing UTUC. METHODS A comprehensive literature search was conducted using PubMed, Scopus, Embase, and Google Scholar for identifying randomized controlled trials (RCTs) and observational studies that evaluated the outcomes of TLNU and RLNU for UTUC. Continuous variables were represented by weighted mean difference (WMD) and standard mean difference (SMD), while binary variables were represented by odds ratio (OR), with 95% confidence intervals (CIs). The quality was assessed using the Newcastle-Ottawa scale. A sensitivity analysis was performed to evaluate the robustness of the estimates. RESULT Six observational studies were incorporated into this meta-analysis. The overall TLNU was associated with significantly shorter operating time (WMD - 19.85; 95% CI - 38.03 to - 1.68; P = 0.03); longer recovery time of intestinal function (SMD 0.46; 95% CI 0.08 to 0.84; P = 0.02). However, the terms of estimated blood loss (WMD - 5.72; 95% CI - 19.6 to - 8.15; P = 0.42); length of stay (WMD - 0.35; 95% CI - 1.61 to 0.91; P = 0.59), visual analog pain scale (WMD - 0.38; 95% CI - 0.99 to 0.84; P = 0.22); drainage duration (WMD - 0.22; 95% CI - 0.61 to 0.17; P = 0.26); overall complication rates (OR 1.24; 95% CI 0.58 to 2.63; P = 0.58); local recurrence rate (OR 0.6; 95% CI 0.3 to 1.21; P = 0.16); distant metastasis (OR 0.94; 95% CI 0.04 to 20.77; P = 0.97); 1-year overall survival (OS) (OR 0.45; 95% CI 0.1 to 2.01; P = 0.3) showed no difference between TLNU and RLUN. CONCLUSION TLNU provides similar surgical outcomes and oncologic results compared to RLUN; however, TLNU has a shorter procedure time and prolonged intestinal function recovery time. Due to the heterogeneity among the studies, randomized clinical trials with follow-ups in the long term are required to obtain more definite results.
