Evaluation of surgical staging in stage I low malignant potential ovarian tumors.
The charts and pathology specimens of 27 patients with ovarian tumors of low malignant potential were reviewed in an attempt to document the rationale for a second laparotomy in those patients with clinical stage 1 disease and who did not have a complete staging laparotomy at their initial surgery. Four of 13 patients with serous tumors, none of 12 patients with mucinous tumors, and one patient with a mixed tumor of LMP were upstaged at the staging laparotomy. The major morbidity rate associated with the procedure was 7.4%. The low yield of a staging laparotomy in patients with mucinous tumors (0%) does not warrant a second operation. The higher yield of a staging laparotomy in patients with serious tumors (30.8%) suggests that the likelihood of upstaging the disease exceeds the potential morbidity, and for this reason, the procedure may be warranted. However, the specific role of a staging laparotomy even in those with serous tumors awaits further study of the prognostic significance of invasive versus noninvasive implants.
