  1. Legend: Definition 1: a main or secondary diagnosis of renal cancer (ICD-10: C64) and a partial or total nephrectomy (OPS: 5–553, 5–554); definition 2: a main diagnosis of renal cancer and a partial or total nephrectomy; definition 3: a main diagnosis of renal cancer (without a secondary diagnosis of renal pelvis cancer) and a partial or total nephrectomy; all rates are crude rates; SE: standard error of the rate; cases: only cases registered as non-DCO; DCO: death certificate only cases; West: West Germany, East: East Germany; age standard: European Standard Population; Germany: nationwide estimates with the exception of North Rhine-Westphalia, Hesse, and Baden-Württemberg; estimates of completeness of cancer registration were provided by the Robert Koch-Institute[11]; Death certificate only (DCO) cases were excluded from the cancer registry data.
