Summary

This summary is machine-generated.

High serum Interleukin-6 (IL-6) levels predict poor survival and advanced disease in bladder cancer (BC) patients. Tumor tissue IL-6 also correlates with BC stage, suggesting its theranostic potential.

Area of Science:

Oncology
Biochemistry

Background:

Interleukin-6 (IL-6) is linked to poor clinical outcomes in cancer.
Elevated IL-6 serum levels in bladder cancer (BC) correlate with adverse pathology and reduced survival.
IL-6 is a potential therapeutic target, but its role in tumor tissue is understudied.

Purpose of the Study:

To evaluate the prognostic significance of IL-6 in bladder cancer patients.
To investigate IL-6 concentrations within bladder tumor tissues.

Main Methods:

A prospective observational study included 179 BC patients undergoing radical cystectomy.
Preoperative serum samples and tumor tissue from 20 patients were analyzed for IL-6 using ELISA.
IL-6 levels were correlated with clinical and pathological features.

Urothelial cancer

Main Results:

High serum IL-6 independently predicted worse overall survival (OS) and cancer-specific survival (CSS).
Higher IL-6 serum levels were associated with advanced tumor stage, lymph node metastasis, and larger tumor size.
Tumor tissue IL-6 was significantly higher in muscle-invasive BC compared to non-invasive stages.

Conclusions:

Serum IL-6 is a robust predictor of poor prognosis and adverse features in bladder cancer.
IL-6 concentration in tumor tissue correlates with bladder cancer stage.
Further research into IL-6's theranostic role in bladder cancer is warranted.
