Cancer in migrant populations: evidence from a regional oncology network
摘要
Cancer care for vulnerable populations such as migrants remains poorly investigated. The Campania Oncology Network (Rete Oncologica Campana, ROC) was established in Campania, a region of southern Italy, to ensure equitable access to cancer care. This study aimed to assess the proportion and distribution of cancers among migrants within the ROC.
Data were extracted from the ROC digital platform for all cancer cases diagnosed between 2022 and 2025. Adjusted proportionate morbidity ratios (PMRs) were calculated to compare the most common cancer types between migrants and non-migrants.
Among 78,119 adult cancer patients, 2,583 (3.3%) were migrants. Migrants were younger than Italian patients, predominantly female, and largely originated from Europe. Migrant women showed higher proportions of cervical (PMR = 2.91; 95% CI: 2.38–3.54), ovarian (PMR = 1.46; 95% CI: 1.19–1.77), and endometrial cancer (PMR = 1.22; 95% CI: 1.01–1.48). Male migrants had increased proportions of stomach cancer (PMR = 1.37; 95% CI: 1.04–1.77) and hepatocellular carcinoma (PMR = 1.45; 95% CI: 1.12–1.85). Overall, migrants also showed modestly higher proportions of colon (PMR = 1.18; 95% CI: 1.03–1.35) and central nervous system cancers (PMR = 1.57; 95% CI: 1.20–2.03).
Migrants within the ROC display distinct cancer patterns with marked gender differences. Higher proportions of gynecological cancers suggest gaps in access to HPV vaccination and screening, while increased stomach and liver cancers in men may reflect differing exposures. These findings underscore the need for gender-sensitive and culturally tailored strategies to improve cancer prevention, and equitable oncologic care for migrant populations.
