Results

The prognosis after curative resection for solitary ovarian metastases was shown to be relatively favorable as Stage IV colorectal cancer. Resection of ovarian metastases, not only curative resection but also noncurative resection, confers a survival benefit. Prognostic factors were large ovarian metastases, bilateral ovarian metastases, the presence of extraovarian metastases, and remnant ovarian metastases.

Baseline Characteristics

The study included patients diagnosed with ovarian metastasis from CRC between 2000 and 2014 from the 20 Japanese institutions. Primary CRC was histologically diagnosed as adenocarcinoma. The diagnosis of ovarian metastasis was based on histological findings in cases that involved ovarian resection, or imaging findings (e.g. computed tomography, positron emission tomography, and magnetic resonance imaging) in cases that did not resect ovarian metastasis. Cases were excluded if they involved oophorectomy for other diseases, the previous treatment of other pelvic malignancies, or appendix cancer.

Participant flow

Resection of the ovarian metastasis was performed in 252 patients (85.1%), with surgeries classified as curative resection in 121 cases (40.9%) and noncurative resection in 128 cases (43.2%).

Adverse events

Not applicable

Outcome measures

The primary outcome assessed was survival after diagnosis of the ovarian metastasis, which was evaluated according to curative resection, noncurative resection, or nonresection of the ovarian metastasis. The secondary outcomes assessed included prognostic factors for ovarian metastasis in CRC, the clinicopathological characteristics of ovarian metastasis from CRC, and survival of solitary ovarian metastases.
