Regional inequalities in cancer care persist in Italy and can influence survival

Abstract

BackgroundPopulation-based cancer registry studies of care patterns can help elucidate reasons for the marked geographic variation in cancer survival across Italy. The article provides a snapshot of the care delivered to cancer patients in Italy. MethodsRandom samples of adult patients with skin melanoma, breast, colon and non-small cell lung cancers diagnosed in 2003–2005 were selected from 14 Italian cancer registries. Logistic models estimated odds of receiving standard care (conservative surgery plus radiotherapy for early breast cancer; surgery plus chemotherapy for Dukes C colon cancer; surgery for lung cancer; sentinel node biopsy for >1mm melanoma, vs. other treatment) in each registry compared to the entire sample (reference). ResultsStage at diagnosis for breast, colon and melanoma was earlier in north/central than southern registries. Odds of receiving standard care were lower than reference in Sassari (0.68, 95%CI 0.51–0.90) and Napoli (0.48, 95%CI 0.35–0.67) for breast cancer; did not differ across registries for Dukes C colon cancer; were higher in Romagna (3.77, 95%CI 1.67–8.50) and lower in Biella (0.38, 95%CI 0.18–0.82) for lung cancer; and were higher in Reggio Emilia (2.37, 95%CI 1.12–5.02) and lower in Ragusa (0.27, 95%CI 0.14–0.54) for melanoma. ConclusionsNotwithstanding limitations due to variations in the availability of clinical information and differences in stage distribution between north/central and southern registries, our study shows that important disparities in cancer care persist across Italy. Thus the public health priority of reducing cancer survival disparities will not be achieved in the immediate future.
