Competing-risks nomogram for predicting cancer-specific death in upper tract urothelial carcinoma: a population-based analysis.

ABSTRACT:

Objective

This study aimed to use a competing-risks model to establish a nomogram to accurately analyse the prognostic factors for upper tract urothelial carcinoma (UTUC) cancer-specific death (CSD).

Design

Retrospective observational cohort study.

Setting

The programme has yielded a database of all patients with cancer in 18 defined geographical regions of the USA.

Participants

We selected patients with UTUC from the latest edition of the Surveillance, Epidemiology, and End Results database from 1975 to 2016. After excluding patients with unknown histological grade, tumour size and lymph node status, 2576 patients were finally selected.

Primary and secondary outcome measures

We used the Fine-Gray proportional subdistribution hazards model for multivaria
