This study aimed to characterize peripheral immune profiles and circulating tumor markers in women with ovarian endometrioma (OE) and deep infiltrating endometriosis (DIE), and to explore their associations with disease severity, symptom burden, and physical health perception. Peripheral blood leukocyte subsets, plasma cytokines, and tumor markers (CA125, CA19-9, CEA, HE4) were analyzed in 146 patients and 50 healthy controls. OE was associated with increased monocyte counts and reduced neutrophil proportions, while DIE showed elevated levels of IL-8 and Galectin-1. IL-33 levels correlated negatively with the revised American Society for Reproductive Medicine (rASRM) scores and positively with neutrophil proportion, suggesting a role in systemic immune regulation. Tumor marker levels varied by subtype: CA19-9 was higher in OE, and CEA in DIE. CA125 correlated with disease severity, and CEA with monocyte levels. Exploratory heatmaps revealed consistent immune-tumor associations linked to anatomical severity and symptom profiles. Although exploratory, these findings highlight the presence of distinct systemic immune patterns in endometriosis and support the potential of integrative blood-based biomarkers for future diagnostic and stratification strategies.<\/jats:p>","DOI":"10.3390\/ijms26199581","type":"journal-article","created":{"date-parts":[[2025,10,1]],"date-time":"2025-10-01T11:06:02Z","timestamp":1759316762000},"page":"9581","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Systemic Immune and Tumor Marker Profiles in Ovarian and Deep Infiltrating Endometriosis: Associations with Disease Severity and Symptom Burden"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6938-504X","authenticated-orcid":false,"given":"Tamara N.","family":"Ram\u00edrez-Pavez","sequence":"first","affiliation":[{"name":"Biochemistry and Molecular Biology (B) and Immunology Department, School of Medicine, IMIB and Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, Universidad de Murcia, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3349-8445","authenticated-orcid":false,"given":"Pilar","family":"Mar\u00edn-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Gynecology and Obstetrics Service, Hospital General Universitario Santa Luc\u00eda, 30202 Cartagena, Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-9210-246X","authenticated-orcid":false,"given":"Ana","family":"Nebot","sequence":"additional","affiliation":[{"name":"Gynecology and Obstetrics Service, Hospital General Universitario Santa Luc\u00eda, 30202 Cartagena, Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Garc\u00eda-Izquierdo","sequence":"additional","affiliation":[{"name":"Biochemistry and Molecular Biology (B) and Immunology Department, School of Medicine, IMIB and Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, Universidad de Murcia, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc\u00eda","family":"Nieto-Meca","sequence":"additional","affiliation":[{"name":"Gynecology and Obstetrics Service, Hospital Cl\u00ednico Universitario Virgen de la Arrixaca, 30120 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6056-4738","authenticated-orcid":false,"given":"Roc\u00edo","family":"S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Gynecology and Obstetrics Service, Hospital General Universitario Reina Sof\u00eda, 30003 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco","family":"Machado-Linde","sequence":"additional","affiliation":[{"name":"Biochemistry and Molecular Biology (B) and Immunology Department, School of Medicine, IMIB and Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, Universidad de Murcia, 30100 Murcia, Spain"},{"name":"Gynecology and Obstetrics Service, Hospital General Universitario Reina Sof\u00eda, 30003 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5765-8231","authenticated-orcid":false,"given":"Mar\u00eda","family":"Mart\u00ednez-Esparza","sequence":"additional","affiliation":[{"name":"Biochemistry and Molecular Biology (B) and Immunology Department, School of Medicine, IMIB and Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, Universidad de Murcia, 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1038\/s41572-018-0008-5","article-title":"Endometriosis","volume":"4","author":"Zondervan","year":"2018","journal-title":"Nat.
