Combining serum inflammatory markers and clinical factors to predict survival in metastatic urothelial carcinoma patients treated with immune checkpoint inhibitors.

Background: Despite the revolutionary impact of immune checkpoint inhibitors (ICIs) on the treatment of metastatic urothelial carcinoma (mUC), the clinical utility of reliable prognostic biomarkers to foresee survival outcomes remains underexplored.

Objectives: The purpose of this study was to ascertain the prognostic significance of serum inflammatory markers in mUC patients undergoing ICI therapy.

Design: This is a retrospective, multicenter study.

Recurrence risk of erythropoiesis-stimulating agents on early-stage urothelial carcinoma in patients with end stage renal disease.

Urothelial carcinoma (UC) predominantly arises in the bladder, but upper tract urothelial carcinomas (UTUCs) comprise 5-10% of cases. Patients with end-stage renal disease (ESRD) are at increased risk for UC, and erythropoiesis-stimulating agents (ESAs) are frequently used to manage anemia in ESRD. However, ESA use in cancer patients raises concerns about tumor progression and survival outcomes.

Antibody-drug conjugates targeting HER2 for the treatment of urothelial carcinoma: potential therapies for HER2-positive urothelial carcinoma.

Urothelial carcinoma (UC) is a common cancer characterized by high morbidity and mortality rates. Despite advancements in treatment, challenges such as recurrence and low response rates persist. Antibody-drug conjugates (ADCs) have emerged as a promising therapeutic approach for various cancers, although their application in UC is currently limited.

The impact of body mass index on survival endpoints among patients with metastatic urothelial carcinoma undergoing treatment with immune checkpoint inhibitors: A real-world multicenter analysis.

Background: Studies on the correlation between high body mass index (BMI) and extended survival among patients receiving immune checkpoint inhibitors (ICIs) have been made, although findings have shown variability. Our research explored the phenomenon of the "obesity paradox" in patients with metastatic urothelial carcinoma (mUC) undergoing treatment with ICIs.

Materials And Methods: We conducted a retrospective analysis of patients diagnosed with mUC who received a minimum of one cycle of ICI treatment at two medical centers in Taiwan from September 2015 to January 2023.

Materials And Methods: We identified patients diagnosed with metastatic prostate cancer from the Chang Gung Research Database spanning the years 2007 to 2020.

Prevalence and oncologic impact of chronic kidney disease for upper tract urothelial carcinoma in endemic area.

Objective: This study aimed to assess the impact of preoperative chronic kidney disease (CKD) on the oncological outcomes of patients with upper tract urothelial carcinoma (UTUC) who underwent standard radical nephroureterectomy (RNU).

Methods: A total of 1172 UTUC patients who received RNU at a single center in Taiwan between February 2005 and August 2019 were included. The patients were categorized into two groups based on their preoperative CKD stage: CKD stage ≤3 (811 patients) and CKD stage >3 (361 patients).

MicroRNA-145-5p suppresses cell proliferation, migration, and invasion in upper tract urothelial carcinoma by targeting 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase.

Upper tract urothelial carcinoma (UTUC), including renal, pelvic, and ureteral carcinoma, has a high incidence rate in Taiwan, which is different from that in Western countries. Therefore, it is imperative to elucidate the mechanisms underlying UTUC growth and metastasis. To explore the function of miR-145-5p in UTUC, we transfected the BFTC909 cell line with miR-145-5p mimics and analyzed the differences in protein levels by performing two-dimensional polyacrylamide gel electrophoresis.

Inhibiting WEE1 Augments the Antitumor Efficacy of Cisplatin in Urothelial Carcinoma by Enhancing the DNA Damage Process.

Urothelial carcinoma (UC) is characterized by a high incidence of mutation, and overcoming resistance to cisplatin-based chemotherapy in UC is a major concern. Wee1 is a G2/M phase regulator that controls the DNA damage response to chemotherapy in -mutant cancers. The combination of Wee1 blockade with cisplatin has shown synergistic efficacy in several types of cancers, but little is known regarding UC.

VCAN Hypomethylation and Expression as Predictive Biomarkers of Drug Sensitivity in Upper Urinary Tract Urothelial Carcinoma.

Versican (VCAN), also known as extracellular matrix proteoglycan 2, has been suggested as a potential biomarker in cancers. Previous research has found that VCAN is highly expressed in bladder cancer. However, its role in predicting outcomes for patients with upper urinary tract urothelial cancer (UTUC) is not well understood.

The prognostic impact of lymphovascular invasion for upper urinary tract urothelial carcinoma: A propensity score-weighted analysis.

Lymphovascular invasion (LVI) predicts poor survival in patients with pathologically localized or locally advanced upper urinary tract urothelial carcinoma (UT-UC). However, LVI is associated with high tumor grade, tumor necrosis, advanced tumor stage, tumor location, concomitant carcinoma in situ, lymph node metastasis, and sessile tumor architecture. These factors might interfere with the analysis of the impact of LVI on oncological prognosis.

Treatment outcomes with radium-223 in docetaxel-naïve versus docetaxel-treated metastatic castration-resistant prostate cancer patients: Real-world evidence from Taiwan.

While radium (Ra)-223 is among the multiple, known life-prolonging treatments in bone-predominant metastatic castration-resistant prostate cancer (mCRPC), optimal treatment sequencing has not been determined, particularly in the Asia-Pacific context. Hence, we aimed to compare treatment outcomes of docetaxel-naïve and post-docetaxel mCRPC patients undergoing Ra-223 therapy in Taiwan. Using a single-center retrospective cohort design, we reviewed records of adult patients receiving Ra-223 for bone-metastatic mCRPC from 2018 to 2021.

The lowest level of tumor involvement is a significant prognostic factor for upper tract urothelial carcinoma after radical nephroureterectomy: A large retrospective cohort study.

Purpose: To evaluate the prognostic impact of the lowest level of tumor location for upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU).

Materials And Methods: Data were collected from patients with UTUC treated with RNU (01/2005- 06/2020) at a single center in Taiwan. Patients were stratified by the lowest level of tumor location into three groups: renal pelvis only (RPO), above upper ureter (AUU), and below upper ureter (BUU).

Totally X-ray-Free Ultrasound-Guided Mini-Percutaneous Nephrolithotomy in Galdakao-Modified Supine Valdivia Position: A Novel Combined Surgery.

We introduced a novel surgery that combines ultrasound guidance, miniaturization and Galdakao-modified supine Valdivia (GMSV) position in percutaneous nephrolithotomy (PCNL) and evaluated the safety and efficacy. This retrospective, single-center study retrospectively reviewed 150 patients who underwent ultrasound-guided mini-PCNL in the GMSV position from November 2019 to March 2022. All perioperative parameters were collected.

Evasion of NK cell immune surveillance the vimentin-mediated cytoskeleton remodeling.

Cancer immunotherapy uses the immune system to achieve therapeutic effects; however, its effect is still limited. Therefore, in addition to immune checkpoint-based treatment, the development of other strategies that can inhibit cancer cells from resisting immune cytotoxicity is important. There are currently few studies on the mechanism of tumors using cytoskeletal proteins reorganization to participate in immune escape.

Prognostic Significance of Galectin-1 but Not Galectin-3 in Patients With Lung Adenocarcinoma After Radiation Therapy.

Introduction: To investigate the role of tumor galectin-1 and galectin-3 in patients with lung adenocarcinoma after definitive radiation therapy.

Methods: A total of 41 patients with localized lung adenocarcinoma undergoing thoracic radiation therapy without concurrent chemotherapy were enrolled. Their paraffin-embedded lung tissues were sent for immunohistochemical staining for galectin-1 and galectin-3.

DNA Hypomethylation Is Associated with the Overexpression of INHBA in Upper Tract Urothelial Carcinoma.

Urothelial carcinoma includes upper urinary tract cancer (UTUC) and bladder cancer. Although nephroureterectomy is the standard treatment for UTUC, the recurrence rate is approximately half and the tumor is associated with poor prognoses. Metastases are the most devastating and lethal clinical situation in urothelial carcinoma.
