Interval carcinoma is defined as a carcinoma detected between two mammographic screening rounds after a negative screening.
By some authors these carcinomas are considered to be more aggressive than screen-detected carcinomas.
In a group of 937 patients referred for breast cancer in the period 1975-1990,76 interval carcinoma patients were treated.
In a retrospective study the outcome was studied of patients with an interval carcinoma in comparison with patients with screen-detected carcinomas and of patients with clinically detected carcinomas outside the screening program.
No significant difference was found in the 5-year and 10-year disease-free survival of patients with interval carcinoma (80%, 68%) and the screen-detected group (89%, 81%) (P=0.12).
The interval group did significantly better than the patients with carcinomas detected outside the screening program (P=0.03).
Interval-detected cancers for patients in the screening program had an outcome intermediate between patients with screen-detected cancers and patients with cancers detected outside the screening program.
The difference between interval-detected cancers and cancers detected outside the screening program was significant, whereas the difference between screen-detected and interval cancers was not.
