Specific sites of metastasis for 40 cases analyzed in this study.

The table summarizes the presence of recurrences in our sample. Data on the site of metastasis sites are missing from three patients. A higher nuclear FMRP expression was detected in patients with multiple metastases (Mann-Whitney U test, p = 0.018 between the "multiple metastasis" group and "single metastasis" group), whereas the difference between the two groups for cytoplasmic FMRP was slightly above the threshold (p = 0.054).
