Objectives The primary objective of this study was to describe the clinical management and surgical treatment of production size pigs (PrdP) with uterine neoplasia. A secondary objective was to compare tumor diagnoses as well as short‐ and long‐term survival between PrdP and a published report of pot‐bellied pigs (PBP) following surgical intervention. Study design Retrospective clinical study. Animals or sample population Client‐owned PrdP (n = 13) treated with exploratory celiotomy ±ovariohysterectomy for uterine neoplasia. Methods Medical records from a university hospital were reviewed for historical treatment, presenting complaint, clinical signs, diagnostics, surgical intervention, pathology, and outcome. An online owner survey was performed for follow‐up. The novel PrdP cohort was compared to a previously published PBP cohort for differences in tumor diagnoses, surgical complications, and survival. Descriptive statistics, Fischer's exact tests and odds ratios were reported. Results PrdP were affected by uterine leiomyoma (4/11), leiomyosarcoma (2/11), adenoma (1/11), adenocarcinoma (3/11), and carcinosarcoma (1/11) with no difference in tumor types between PrdP and PBP. PrdP surviving to hospital discharge (6/13) survived at least 1 year postoperatively, with median follow‐up of 16 months (14‐60 months). PrdP were less likely than PBP to survive in the short‐term despite similar frequencies of marked intraoperative hemorrhage. PrdP and PBP had comparable rates of long‐term survival following hospital discharge. Conclusion PrdP are afflicted by similar uterine neoplasia diagnoses as PBP, but they have lower rates of short‐term survival to hospital discharge with surgical treatment. Clinical significance/impact PrdP have a guarded prognosis for survival to hospital discharge when operated for uterine neoplasia.
