The objective of this study was to assess the incidence, treatment, and survival patients with synchronous peritoneal metastases (PM) from extraperitoneal primary tumors. A cohort selected Netherlands Cancer Registry (NCR), in which all diagnosed PM 2017 2018 were screened for eligibility. five most common origins included further analyses: lung, breast, urinary tract, kidney cancer malignant melanoma. Survival investigated using log-rank test between different tumor locations. In total, 480 origins. proportion per origin ranged 0.1 1.1%, highest lung patients.
