Kidney Cancer Diagnosis, Treatment, and Survival Trends in England (2013-2019)

What is it about?

The study analyzed NHS Digital data on patients diagnosed with kidney cancer in England from 2013 to 2019. The incidence of new kidney cancer diagnoses increased, but the age-standardized rates were stable. Almost half of patients were diagnosed through non-urgent general practitioner referrals. The survival outcomes differed by Stage, histological subtype, and social deprivation class. The study found that the rising incidence of kidney cancer is likely multifactorial, including an aging and growing population, increased cross-sectional imaging, and exposure to risk factors.

Why is it important?

This research is important because it provides valuable insights into the incidence, diagnosis, treatment, and survival of kidney cancer patients in England using routinely collected real-world data. It helps to objectively understand the presentation, diagnosis, and treatment of kidney cancer and can be used as a benchmark for future commissioned national kidney cancer audits. Key Takeaways: 1. Kidney cancer incidence in England has risen by 13.7% from 2013 to 2019, with no clear evidence of stage migration, unlike trends seen in the United States. 2. The use of urgent cancer referral pathways increases cancer detection and reduces diagnostic delays, but challenges arise around the 2-week wait (2WW) pathway for suspected kidney cancer due to its broad symptom signature. 3. The study found that almost half of patients were aged 0-70 years, and the cohort was most frequently diagnosed with Stage 1-2 kidney cancer. Most patients were diagnosed through non-urgent general practitioner referrals, followed by 2-week-wait and emergency routes. 4. Survival outcomes differed by stage, histological subtype, and social deprivation class, with age-standardized mortality rates remaining relatively unchanged over the study duration.
