Acquired Angioedema in Selected Neoplastic Diseases

Abstract

Background and Objectives. Acquired angioedema is a relatively common revelation accompanying some diseases such as autoimmune or cancer. The study aimed to assess the incidence of one subtype of angioedema—C1-INH-AAE (acquired angioedema with C1 inhibitor deficiency). Material and methods. The study was retrospective and based on 1 312 patients with a final diagnosis of breast cancer, colorectal cancer, or lung cancer: 723 women and 589 men with a mean age of 58.2 ± 13.5 years. The cancer diagnosis according to the ICD (International Classification of Diseases)-10 code, medical history including TNM (Tumour, Node, Metastasis) staging, histopathology, and assessment of the occurrence of C1-INH-AAE angioedema were analysed. Results. C1-INH-AAE occurred more often in patients with cancer than in the control group, as follows: 327 (29%) vs. 53 (6%) for p < 0.05. C1-INH-AAEs were observed most often in the group of patients diagnosed with breast cancer compared to colorectal and lung groups: 197 (37%) vs. 108 (26%) vs. 22 (16%) (p < 0.05). A higher incidence of C1-INH-AAE was observed in the early stages of breast cancer. However, there was no relationship between the occurrence of C1-INH-AAE and the BRCA1 (Breast Cancer gene 1)/BRCA2 (Breast Cancer gene 2) mutation or histopathological types of breast cancer. Conclusion. Angioedema type C1-INH-AAE occurs more often in patients with selected neoplastic diseases, especially in the early stages of breast cancer.

Unveiling Therapeutic Frontiers: DON/DRP-104 as Innovative Plasma Kallikrein Inhibitors Against Carcinoma-Associated Hereditary Angioedema Shocks - A Comprehensive Molecular Dynamics Exploration

“…Particularly crucial is the incorporation of prodrug or advanced drugdelivery systems to bolster efficacy while minimizing off-target tissue toxicities. Although the association between Hereditary Angioedema (HAE) and malignancy is not well-defined, certain cancers have been linked to acquired angioedema (AAE), and comorbidity between HAE and cancer has been observed [19,20]. It is noteworthy that accumulating research suggests a link between the dysregulation of plasma kallikrein (PKa) and the progression of various carcinomas, including lung [21], pancreatic [22], colorectal [23], and breast [24] cancers.…”
