Cancer staging statistics 19¶
The below statistics were taken from the cancer_staging_consolidated LabKey table from the Main Programme V19 data release. The table is built from the participant IDs and Tumour Sample Plate-key IDs from the cancer_analysis table which comprises QC-passed and interpreted tumour-normal genome pairs.
Completion as a percent of samples in the cancer_analysis table¶
This table shows the rate of data completion as a percentage of the total number of distinct participants and distinct tumour sample plate-keys in the cancer_analysis table vs the cancer_staging_consolidated table. Please note that this indicates the number of entries (participants or tumour sample plate-keys, respectively) for which we have stage information from one of the three input sources (cancer_participant_tumour, av_tumour, sact) within 12 months of acquiring the tumour sample. No additional checks were conducted.
# | cancer_analysis | cancer_staging_consolidated | % complete |
---|---|---|---|
Distinct Participants | 15,237 | 12,645 | 82.99 |
Distinct Tumour Sample Plate-keys | 16,369 | 13,483 (number of rows in cancer_staging_consolidated table) | 82.37 |
Completion rates of cancer_staging_consolidated by each source of staging¶
This table shows the number and rate of completion of tumour_sample plate-keys (n = 13,483) that are linked each of the three sources of staging. Note the link must be within a year of the tumour_clinical_sample_time field from the cancer_analysis table.
Source | Number of tumour sample plate-keys | % complete |
---|---|---|
av_tumour | 12,873 | 95.48 |
cancer_participant_tumour | 5,843 | 43.34 |
sact | 3,529 | 26.17 |
Summary and Distribution of time-difference days between tumour clinical sample time and staging information¶
This table shows the summary statistics of the distribution of time (in days) between the tumour_clinical_sample_time and the date of staging data acquisition. This is broken down by the three sources of staging.
NB: Note that in the below table and histogram, positive values indicate that the date of staging data acquisition is before the tumour_clinical_sample_time. Negative values indicate that the date of staging data acquisition is after the tumour_clinical_sample_time.
Stat | cancer_participant_tumour | av_tumour | sact |
---|---|---|---|
minimum | -365 | -360 | -365 |
q1 | 0 | 17 | -70 |
median | 16 | 39 | -49 |
mean | 31.61 | 57.52 | -39.21 |
q3 | 48 | 70 | -23 |
maximum | 365 | 365 | 365 |
NA | 7,640 | 610 | 9,954 |
The below histograms show the same data but as a frequency distribution.
Frequency of the nearest staging source to the tumour clinical sample time for each tumour sample plate-key¶
The below table shows the break down of the tumour_sample plate-keys (n = 13,483) by the nearest source of staging data. For example if a tumour_sample plate-key has both linked av_tumour and sact staging entries, then the nearest entry to the tumour_clinical_sample_time is taken.
Staging Source | Frequency |
---|---|
cancer_participant_tumour | 4,656 |
av_tumour | 7,548 |
sact | 1,279 |
Frequency of breakdown by combination of data sources for each tumour sample plate-key¶
This table shows the frequency breakdown of the three sources of staging data across the tumour_sample plate-keys (n = 13,445). For example, if a tumour_sample plate-key has only cancer_participant_tumour and sact data available, then these two data sources are marked as Y.
cancer_participant_tumour | av_tumour | sact | Frequency |
