Skin - Pathology

This is the site specific section for additional skin cancer specific data items to be recorded. These will be aligned within the schema to form a single report. Data items within the following groups have been re-ordered to improve data collection and prevent errors, in some cases the same data item may be collected within more than one section.

From v5, two new sections have been added for Merkel Cell Carcinoma and Cutaneous Adnexal Carcinoma.

Important notice:

To improve the data quality and accuracy of data submitted, a new choice has been added to this section to some tumour groups where applicable. This will allow for only the specific disease data items to be submitted alongside the Core Pathology data items and prevent any accidental addition of other disease specific items in each pathology report submitted.

This section allows for only Basal Cell Carcinoma (BCC) data to be recorded.

May be one occurrence per pathology report (0..1)

Start of Repeating Item - Skin Cancer Perineural Invasion Indicator

End of Repeating Item - Skin Cancer Perineural Invasion Indicator

Breslow Thickness

Breslow thickness in mm, can be recorded to nearest 0.01mm where clinically appropriate.

Note:

• Breslow thickness should be measured to a minimum of one decimal place but at times to a greater degree of precision as to allow accurate

Tumour Infiltrating Lymphocytes (TILS)

Type of TILS. Tumour infiltrating lymphocytes (TILS) are white blood cells that have left the bloodstream and migrated into a tumour.

This is a new section in v5 and allows for only Merkel Cell Carcinoma (MCC) data to be recorded.
