Collection and usage attributes
|Guide for use:|
To be reported when therapy is received after a diagnosis of cancer and prior to primary surgical treatment.
This data item is used to flag cases in which tumour descriptors, for example solid tumour size, may be inaccurate due to shrinkage from neoadjuvant therapy.
Yes - indicates that the client has received neo-adjuvant therapy after a diagnosis of cancer and prior to primary surgical treatment
No - indicates that the client did not receive neo-adjuvant therapy after a diagnosis of cancer and prior to primary surgical treatment
For invasive breast cancer:
Information is obtained from
Preoperative chemotherapy and/or radiotherapy may be received after a diagnosis of cancer but before surgical treatment.
The effects of chemotherapy and/or radiotherapy prior to surgery will shrink the tumour and so the size of the tumour found from the subsequent surgical excision will be smaller than the original size of the tumour at the time of diagnosis. This impacts on the TNM-T and staging classification, and is important to take into account for analysis and research.
