A Overall survival. Among elderly patients 75 years or older, the 5-year overall survival rate was slightly lower in the follow-up group (62.8%) than in the additional operation group (81.8%, p = 0.232).

Among elderly patients 75 years or older, the 5-year cause-specific survival rate did not differ significantly between the additional operation group (100%) and the follow-up group (91.2%, p = 0.283)
