Endoprosthetic Reconstruction for a Displaced Atypical Femoral Fracture in a Cancer Patient with Poor Prognosis

Prognosis predictors for metastatic breast cancers.

(a) Revised Katagiri scoring system, which is useful for predicting bone metastatic cancers. The parameters are primary site, visceral metastases, laboratory data, ECOG performance status, previous chemotherapy, and multiple skeletal metastases. The prognosis is predicted as follows: 0–3: low risk; 4–6: intermediate risk; 7–10: high risk

Parameter	Value	Points
Primary site	Hormone-dependent breast cancer	0
Visceral metastases	Liver/pleural metastasis	2
Laboratory data	Total bilirubin: 1.65	2
Performance status	PS 4	1
Previous chemotherapy	Yes	1
Multiple skeletal metastases	Yes	1
Total		7

(b) An internally and externally validated prognostic score for metastatic breast cancer developed by Dr. Regierer. The parameters are metastasis-free interval, hormone receptor, and metastases of the liver, effusion, brain, bone, bone marrow, soft tissue, and lungs. The score predictions are as follows: 0–8: low risk; 9–14: intermediate; ≥15: high risk

Parameter	Value	Points
Metastasis-free survival	<2 years	3
Hormone receptor	Positive	0
Liver	Yes	7
Effusion	Yes	4
Brain	No	0
Bone	Yes	4
Bone marrow	No	0
Soft tissue	No	0
Lung	No	0
Total		18
