ABSTRACT

BACKGROUND/OBJECTIVE: The aim of this study was to identify the mammographic findings associated with malignancy in different age groups, taking into account breast composition (BC) and lesion size. METHODS: Preoperative mammograms of 1023 invasive ductal carcinomas were retrospectively evaluated. According to the American College of Radiology Breast Imaging Reporting and Data System, cancer mammographic findings were classified as mass, calcifications, architectural distortion and asymmetry, and breasts were assessed as non-dense (A or B BC) and dense (C or D BC). Patient cohort was subdivided into three age groups (group 1: <50 years of age; group 2: between 50 and 69; group 3: ≥70 years of age). RESULTS: Significant results of multinomial logistic regression were the association between mass and non-dense breast (p < 0.0001) and the association between mass and tumor size larger than 15 mm (p = 0.0049). CONCLUSIONS: Mass finding of invasive ductal breast carcinoma is associated with breast composition and tumor size.

ABSTRACT

PURPOSE: The aim of this study was to evaluate mammographic findings associated with invasive lobular carcinoma in different age groups, taking into account breast composition and tumour size. MATERIAL AND METHODS: A total of 1023 invasive lobular carcinoma preoperative mammograms were evaluated. According to the American College of Radiology Breast Imaging Reporting and Data System, cancer mammographic findings were classified as mass, calcifications, architectural distortion, and asymmetry, and breasts were assessed as dense (C or D breast composition) or non-dense (A or B). The patient cohort was subdivided into 3 age groups (< 50, 50-69, ≥ 70 years of age). In order to make the size and age groups dichotomous variables and to perform multiple regression analysis, a cut-off of 10 mm was chosen for tumour size, and < 50-years-old and 50-69-years-old age groups were grouped together (< 70-years-old age group). RESULTS: Significant results of multivariate analysis were the association between mass finding and non-dense breasts and size ≥ 10 mm (p < 0.0001), between calcifications, and dense breasts, size < 10 mm and < 70-years-old age group (p < 0.0001), between distortion and < 70-years-old age group (p = 0.0366), and between asymmetry and ≥ 70-years-old age group (p = 0.0090). CONCLUSIONS: Various mammographic findings are differently associated with age group, breast composition, and tumour size.

ABSTRACT

We present a case of ductal carcinoma in situ within a fibroadenoma. Breast cancer arising within fibroadenoma incidence ranges from 0.125% to 0.02%, and ductal carcinoma in situ is not the most frequent malignancy that can be found within a fibroadenoma. Dynamic contrast-enhanced magnetic resonance imaging showed an oval mass with circumscribed margins and dark internal septations, suspicious for fibroadenoma. According to European Society of Breast Radiology diffusion-weighted imaging consensus, mean apparent diffusion coefficient value obtained by drawing a small region of interest on the lesion apparent diffusion coefficient map showed a low diffusion level. Therefore, ductal carcinoma in situ within a fibroadenoma was diagnosed at final pathology after surgical excision.

ABSTRACT

Objective To explore the value of transperineal prostate biopsy guided by contrast-enhanced ultrasound(CEUS)and MR diffusion weighted imaging (DWI).Methods 128 patients with suspected prostate cancer were analyzed.Both MR diffusion weighted imaging(MRDWI)and contrast-enhanced ultrasound(CEUS) were applied before prostate tissue was biopsied .The suspected lesion was confirmed by specialists of MRI , Ul-trasound and Urological together .The regular six normal sites addition to suspected lesion were biopsied .Biopsy specimens were sent to pathological examination separately with defined puncture site .The sensitivity, specificity and accuracy of MRDWI , CEUS alone and the combination of two methods were analyzed .Results Of the 858 prostatic specimens from 128 patients , 278 specimens were positive , with 172 specimens found by MRDWI and 114 specimens found by CEUS .As for 278 positive specimens , 137 specimens were diagnosed by MRDWI cor-rectly rather than CEUS , and 79 specimens were diagnosed by CEUS correctly rather than MRDWI , 35 specimens were diagnosed by either MRDWI or CEUS and 27 specimens were diagnosed by neither MRDWI nor CEUS .The sensitivity,specificity,accuracy of biopsy guided by MRDWI , CEUS and both of them in diagnosis of prostate cancer were 61.87%,85.00%,77.51%;41.01%,93.97%,76.81% and 90.29%,80.52%,83.68%,respec-tively.The sensitivity and accuracy of biopsy guided by both MRDWI and CEUS were higher than MRDWI or CEUS alone, with statistically significant difference(P<0.05).Conclusions Suspicious lesions may be found more frequently by MRDWI than CEUS , however two methods can complement each other .Sensitivity and accura-cy of biopsy can be improved by the combination of MRDWI and CEUS , which should be recommended in future clinical practice , without increasing the number of needle .
