Table 1 Percentage of cases staged, by cancer type and process used. Percentages shown are cumulative, beginning from the left.

From: Collection of population-based cancer staging information in Western Australia – a feasibility study

Cancer type Staged from WACR data alone (%) Staged from WACR and HBCRs, WARTN (%) Staged after all completed steps (no assumptions) (%) Staged after all steps with assumption/s (%)
Group A: Could be staged now
Ovary 60^ 100 100 100
Cervix 16^ 95 100 100
Uterus 50^ 85 95 95
Group B: Could be staged now, making MX = M0 assumption
Breast 0 12 65 95
Colorectal 12^ 53 80 92
Group C: Could be staged now, with NX = N0 and MX = M0 assumptions
Melanoma 0 (0) 57 100
Prostate 2 5 34 97
Group D: Could be started now with MX = M0, but long term collection requires system changes
Stomach** 25 25 70 95
Lung 18 38 76 86
Pancreas 45 45 70 80
Thyroid** 10 10 47 79
Testis** 10 10 75 75
Kidney** 15 20 65 70
Group E: Staging not feasible at present
Oesophagus** 0 0 50 65
Bladder** 0 0 40 55
Lip 0 (0) 37 42
Lymphoma 44 (44) 44 44
Myeloma 0 (0) 0 0
Leukaemia 0 (0) 0 0
Brain 0 (0) 0 0
  1. ^ These numbers could have been higher as the external databases were searched first, and WACR later searched only for incomplete cases.
  2. ** Only one HBCR currently collects data on these cancers except bladder, for which two HBCRs are collecting data.
  3. () Numbers in parentheses indicate that the additional data source/s indicated by the column header, was/were not accessed as they were either not applicable to the cancer type, or research suggested the additional effort would be unrewarding.
