Abstract
Background
Lymphopenia is associated with poor outcomes in patients with various cancers, but little is known about the prognostic impact of lymphopenia in patients with epithelial ovarian cancer (EOC) after induction chemotherapy (IC). This study investigated the prognostic significance of pre- and post-IC lymphopenia in patients with advanced EOC.
Methods
We reviewed medical records of 68 patients with stage III/IV ovarian, fallopian tube, or peritoneal cancer treated with IC at our institution between 2009 and 2017. We assessed the associations of pre- and post-IC inflammatory markers, including lymphocyte counts, with several oncological outcomes, such as the implementation of interval debulking surgery (IDS), complete resection, progression-free survival (PFS), and overall survival (OS).
Results
Lymphocyte counts increased significantly post-IC compared with the pre-IC values (P = 0.009). Pre-IC lymphopenia was observed in 27 patients (40%), whereas only 16 patients (24%) displayed lymphopenia post-IC (P = 0.020). Among several inflammatory markers, only post-IC lymphopenia was significantly associated with incomplete resection outcome during IDS (P = 0.012). Moreover, post-IC lymphopenia was significantly associated with poor PFS (log-rank test, P = 0.009), whereas pre-IC lymphopenia was associated with neither PFS nor OS.
Conclusions
Post-IC lymphopenia may predict incomplete resection during IDS and poor prognosis in patients with advanced EOC.
