Consistency of recording of chemotherapy cycles in the National Cancer Registration and Analysis Service Systemic Anti-Cancer Therapy database and the Hospital Episode Statistics Admitted Patient Care database.

We assessed the extent to which chemotherapy cycles recorded in Hospital Episode Statistics (HES) Admitted Patient Care (APC) were captured in National Cancer Registration & Analysis Service Systemic Anti-Cancer Therapy (SACT) for a cohort of lung cancer patients. All chemotherapy cycles recorded for linkage eligible lung cancer patients with a National Cancer Registration & Analysis Service diagnosis between 2012 and 2015 were identified in HES APC and SACT. Among a population of 4070 lung cancer patients, 6076 chemotherapy cycles were observed in HES APC data.

Suspected cancer symptoms and blood test results in primary care before a diagnosis of lung cancer: a case-control study.

To compare symptoms and blood test results prior to cancer diagnosis in individuals who developed lung cancer and those who did not. Nested case-control study, lung cancer patients were matched to up four controls with no record of cancer. Differences in symptoms and blood test results were investigated in the 2-year period prior to diagnosis.
