Figure 4.

Comparison of femur metastases between breast and prostate carcinomas. The results show that with an increase in the number of metastatic bone lesions, the proportion of metastatic femur lesions of breast carcinoma gradually increased (χ²=13.6, P=0.001), but that of prostate carcinoma did not change (χ²=0.2, P=0.921). In the few bone metastases group, the proportion of metastatic femur lesions of breast carcinoma was significantly lower than that of prostate carcinoma (χ²=3.9, P=0.047).
