title: Triple test score for the evaluation of invasive ductal and lobular breast cancer.
abstract: The aim of our study was to compare the preoperative sum score diagnostics of invasive ductal and lobular cancers using three or four diagnostic methods. The novelty of this study is the examination of this phenomenon based on sum score, no such papers can be found in the literature. Ductal cancers have higher score values indicating easier diagnostics, but the difference in distribution of the scores was significant (p = 0.0086) only in case of the triple-test. The score values give appropriate opportunity to create their order of diagnostic power which was the same by both histologic types and in their subgroups with low sum-score: the strongest was cytology, followed by mammography, ultrasound and physical examination. No significant difference was found between the two histologic group in their mammographic appearances-stellate, circumscribed, assymmetric distortion or microcalcification-(p = 0.0694). In low score subgroup besides the occult forms, structural distortion and indeterminate microcalcifications overweighed the stellate and circumscribed lesions typical for the whole groups. In symptomless cases of both histologic groups only one strongly malignant diagnostic test result warrants the right diagnosis. Summarizing the score distribution of the results in case of four diagnostic tools the higher scores-indicating malignancy-were more frequent in the ductal group compared to the lobular ones. Extra attention has to be paid to rare radiomorphologic appearances and to the most deterministic examination, namely cytology.
