A prospective study to evaluate the role of 2-[18f] fluoro-2-deoxy-d-glucose (FDG)-positron emission tomography (PET), breast magnetic resonance imaging (MRI), and breast ultrasonography in monitoring tumor responses in patients with locally advanced breast cancer (LABC) undergoing neoadjuvant chemotherapy.

Histopathological Results

Objective To investigate the role of positron emission tomography (PET) and magnetic resonance imaging (MRI) in evaluating the feasibility of skin-sparing mastectomy in patients with locally-advanced breast cancer (LABC) who will undergo neoadjuvant chemotherapy (NAC) by evaluating the sensitivity and specificity of PET and MRI compared with skin biopsy results before and after NAC treatment. Methods Patients with LABC who were treated with NAC between November 2013 and November 2015 were included in this study. Demographic, clinical, radiological and histopathological features of the patients were recorded. Results A total of 30 patients were included in the study with a mean age of 52.6 years (range, 35–70 years). Sensitivity and specificity for detecting skin involvement in LABC was 100%/10% (62%/85%) with MRI and 60%/80% (12%/92%) with PET before (after) NAC, respectively. When radiological skin involvement was assessed in relation to the final histopathological results, the preNAC PET results and histopathological skin involvement were not significantly different; and there was no difference between postNAC MRI and histopathological skin involvement. Conclusions As preNAC PET and postNAC MRI more accurately determined skin involvement, it might be possible to use these two radiological evaluation methods together to assess patient suitability for skin-sparing mastectomy in selected patients.

Magnetic Resonance Imaging Mri

Digital breast tomosynthesis (DBT) is a fairly recent breast imaging technique invented to overcome the challenges of overlapping breast tissue. Ultrasonography (USG) was used as a complementary tool to DBT for the purpose of this study. Nonetheless, breast magnetic resonance imaging (MRI) remains the most sensitive tool to detect breast lesion. The purpose of this study was to evaluate diagnostic performance of DBT, with and without USG, versus breast MRI in correlation to histopathological examination (HPE). This was a retrospective study in a university hospital over a duration of 24 months. Findings were acquired from a formal report and were correlated with HPE. The sensitivity of DBT with or without USG was lower than MRI. However, the accuracy, specificity and PPV were raised with the aid of USG to equivalent or better than MRI. These three modalities showed statistically significant in correlation with HPE (p < 0.005, chi-squared). Generally, DBT alone has lower sensitivity as compared to MRI. However, it is reassuring that DBT + USG could significantly improve diagnostic performance to that comparable to MRI. In conclusion, results of this study are vital to centers which do not have MRI, as complementary ultrasound can accentuate diagnostic performance of DBT.

Attention To Detail

Ductography or galactography is a technique used in the diagnostic workup of unilateral, single duct, spontaneous, and bloody or clear nipple discharge. Mammographic imaging with magnification may reveal the source of the discharge. The technique is challenging, yet it can be mastered with attention to detail, a well thought-out protocol, and practice. Imaging findings can be non-specific, yet may guide biopsy or surgical excision. Now with the wide use of breast magnetic resonance imaging (MRI), which has been shown to be more sensitive for lesion detection, ductography is used less frequently. This chapter, appearing in the section on interventions and surgical changes, reviews the indications, procedure protocols, and pitfalls, as well as the management and imaging follow-up for ductography or galactography.
