◇ For three inoperable cases, size information and mitotic rate are missing because there was no surgical specimen. ◐ Mitotic rate was not evaluated in one surgical specimen. ◈ Risk of metastasis was evaluated according to the National Institute of Health (NIH) classification. HPFs: high-power fields; * per 50 HPFs is a total of 5 mm2.
