A family history of tumor (P = .6327), comorbidity (P = .8945), time from the first chemotherapy to surgery (P = .1195), CA125 (P = .4955), CEA (P = .9188), CA199 (P = .2455), CA153 (P = .8042), HE4 (P = .2003), surgical approach (P = .9144), surgical scope (P = .2822), intraoperative bleeding (P = .2498), intraoperative injury (P = .3038), postoperative pathology (P = .7525), chemotherapy regimen (P = .7145), and radiotherapy (P = .5100)did not significantly correlate with overall survival (OS). The gene discussed is CEACAM5; the disease is neoplasm.
