Port Site Metastases: A Survey of the Society of Gynecologic Oncology and Commentary on the Clinical Workup and Management of Port Site Metastases.

STUDY OBJECTIVE: Laparoscopic port site metastases (PSMs) have an incidence of .5% to 2%. The management of an isolated PSM (iPSM), without evidence of recurrence elsewhere, remains unclear. The aim of this study was to elucidate practices regarding iPSMs. DESIGN: A 23-item survey was created using commercially available survey software. Over the course of January 2016 the survey was e-mailed to the members of the Society of Gynecologic Oncology with 2 follow-up reminder e-mails. (Canadian Task Force classification III.) SETTING: Online survey. MEASUREMENTS AND MAIN RESULTS: Of the 709 surveys sent, 132 were returned. Providers practicing for <5 years saw fewer PSMs and those who performed more minimally invasive surgeries (MISs) saw more PSMs. Comparing providers who have or have not seen PSMs, no differences in pneumoinsufflation pressure, the mode of delivery of the specimen, the use of local anesthesia at port site incisions, or the method of deflation were seen. If an iPSM was suspected, most providers indicated they would obtain imaging (computed tomography, 51%, or positron emission tomography/computed tomography, 43%) followed by an interventional radiology-guided biopsy (29%) or resection of the mass. Tendency for treatment is to surgically resect the lesion followed by adjuvant therapy. CONCLUSION: After controlling for time in practice, we did not find a strong risk factor for iPSMs other than performing >75% of oncologic surgeries by MIS. Most respondents performed imaging when suspecting iPSMs and use systemic adjuvant therapy after confirming iPSMs.
