Aims and objectives
Many of a breast cancer is Invasive carcinoma of no special type,
and it is the most common form of invasive breast cancer[1-3].
The three patterns presented in Fig.
1 belong to invasive carcinomas of no special type.
In Japan,
invasive carcinomas of no special type are further classified as solid type,
tubule forming type,
and scirrhous type reflecting differences in tissue morphology,
lymph node metastasis rate,
differentiation degree,
and 10-year survival rate[4-7].
※The old typing(Solid-tubular carcinoma,Papillo-tubular carcinoma,Scirrhous carcinom) has been changed into new typing(Solid type,Tubule forming type,Scirrhous type) from May,
2018.
When one lesion presents a mixed variety of two or more types,
it is classified as a type occupying a large area[4-7].
(In case it is difficult to judge,
it is classified as other type.)
Additionally,
another feature distinguishing the three types is the difference in tumor cell density[4-7].(Scirrhous type < Tubule forming type < Solid type)
In this study,
we compared analysis results of the magnetic resonance imaging (MRI) using the time intensity curve (TIC) for for the benign/malignant differential diagnosis of breast cancer and pathological diagnosis results [8-19].
This is an unknown research field.
