As shown in Table 5, The 1-year survival rate in the non organ metastasis group was 63.8%, while that in the organ metastasis group was only 16.4%, bone metastasis group was 13.8%, brain metastasis group was 19.1%, liver metastasis group was 13.8% and intrapulmonary metastasis group was 20.3%, The 3-year survival rate in the non organ metastasis group was 23.1%, while that in the organ metastasis group was only 1.9%, bone metastasis group was 0.6%, brain metastasis group was 3.1%, liver metastasis group was 0.8% and intrapulmonary metastasis group was 1.8%,The 5-year survival rate in the non organ metastasis group was 8.9%, while that in the organ metastasis group was only 0.2%, brain metastasis group was 0.6%, The other metastasis groups were 0.
