Grading

Pathological features

score

Grade 0

Without metastasis

0

Grade I

There are 1 ~ 5 small metastases less than 1 mm in diameters in the lung and a mitotic figure is occasionally seen in the metastasis

1

Grade II

There are 5 ~ 10 small metastases or 1 ~ 2 intermediate metastases between 1 ~ 2 mm in diameter

2

Grade III

More than 10 small metastases are widely distributed or large metastases more than 2 mm in diameter occur in the lung
