Description

Puente et al reported a prognostic index for a woman with breast cancer that is metastatic at the time of recurrence. This can help to identify a woman who may benefit from the more aggressive or a novel therapy. The authors are from multiple institutions in Spain participating in the GEICAM El Alamo Register.


Patient selection: recurrent breast cancer, not metastatic (Stage IV) at diagnosis, now metastatic

 

Parameters:

(1) age at diagnosis in years (not stated if initial or recurrence, presume recurrence)

(2) clinical stage at initial diagnosis, from I to III

(3) ER and PR status

(4) histologic grade

(5) extracapsular extension in lymph nodes

(6) nodal ratio (number positive to total number)

(7) chemotherapy (neo and/or adjuvant)

(8) dominant site of metastasis

(9) number of recurrence sites

(10) surgery at recurrence

(11) radiotherapy at recurrence

(12) number of chemotherapy agents in metastatic disease

(13) number of hormonal therapy lines in metastatic disease

(14) response to the first line therapy (not stated to initial therapy or at recurrence but text on page 596 suggest at recurrence)
