Abstract
The diagnosis of inflammatory breast cancer ( IBC ) is largely clinical and therefore inherently somewhat subjective. The objective of this study was to evaluate the diagnosis of IBC at two centers in N orth A frica where a higher proportion of breast cancer is diagnosed as IBC than in the U nited S tates ( U . S .). Physicians prospectively enrolled suspected IBC cases at the National Cancer Institute ( NCI ) – C airo, E gypt, and the I nstitut S alah A zaiz ( ISA ), T unisia, recorded extent and duration of signs/symptoms of IBC on standardized forms, and took digital photographs of the breast. After second‐level review at study hospitals, photographs and clinical information for confirmed IBC cases were reviewed by two U . S . oncologists. We calculated percent agreement between study hospital and U . S . oncologist diagnoses. Among cases confirmed by at least one U . S . oncologist, we calculated median extent and duration of signs and S pearman correlations. At least one U . S . oncologist confirmed the IBC diagnosis for 69% (39/50) of cases with photographs at the NCI ‐ C airo and 88% (21/24) of cases at the ISA . All confirmed cases had at least one sign of IBC (erythema, edema, peau d'orange) that covered at least one‐third of the breast. The median duration of signs ranged from 1 to 3 months; extent and duration of signs were not statistically significantly correlated. From the above‐mentioned outcomes, it can be concluded that the diagnosis of a substantial proportion of IBC cases is unambiguous, but a subset is difficult to distinguish from other types of locally advanced breast cancer. Among confirmed cases, the extent of signs was not related to delay in diagnosis. The diagnosis of inflammatory breast cancer ( IBC ) is largely clinical and therefore inherently somewhat subjective. The objective of this pilot study was to evaluate the diagnosis of IBC at two centers in N orth A frica, where a higher proportion of breast cancer is diagnosed as IBC than in the U nited S tates ( U.S. ). The diagnosis of a substantial proportion of IBC cases at the study centers was unambiguous, but a subset was difficult to distinguish from other types of locally advanced breast cancer.Publisher
