Prognostic Value of Lymph Node Parameters in Elderly Patients with Stage III Serous Ovarian Cancer Based on Competing Risk Model
As part of ovarian cancer local involvement with metastasis to lymph nodes changes the staging of the disease and increases the likelihood of non-survival.
This retrospective survey using the US SEEK database looked at reports from almost 150,000 ovarian cancer patients' initial surgery and determined the number of lymph nodes removed at the time of surgery and the number which were positive for metastasis.
Those women who had more than 8 positive nodes had a worse survival. Interestingly those women who had more than 22 nodes examined had better survival than those who had fewer. Presumably this reflects better patient care when metastasis is excluded early or, maybe lymph nodes are more easily removed when negative for metastasis.
easily removed when negative for metastasis?
