    (2022) Gunes, Gozde; Crivellaro, Priscila; Muradali, Derek; 0000-0003-0991-1380; 35924122; G-4374-2017
    Introduction In this retrospective study, we aimed to evaluate benign internal mammary lymph nodes (IMLNs) in terms of frequency, number, size, long axis/short axis (L/S) ratio, intercostal location, presence of fatty hilum, and stability using breast magnetic resonance imaging (MRI) and discuss the findings by reviewing existing literature. Methods This single-center study consisted of 130 women between the ages of 24 and 76 years, who had at least two breast MRI examinations in our institution, with the latest exam performed between January 1, 2019 and November 1, 2019, were eligible for the study. MRIs of the study group were independently reviewed by two radiologists. Results IMLN was detected in 31.1% of the 427 MRIs, with a total number of 256 nodes. The most common indication for breast MRI was high-risk screening (66.2%). The median number of nodes per patient was 1 (range: 1-6). The median follow-up time was 19.5 months (range: 6-141 months). None of these benign nodes showed significant interval growth. Mean L/R ratio of the nodes was 1.9. One hundred and four nodes (n = 104, 40.6%) had a L/S ratio less than 2 and 43.2% (n = 45) of the nodes with a L/S ratio less than 2, had a long axis measuring less than or equal to 3mm. IMLN of patients with breast implants had the largest mean long axis. The fatty hilum was identified in 34.3% (n = 68) of the 256 nodes. The size of the lymph nodes where fatty hilum was visualized was significantly larger than the ones where fatty hilum was not visualized (p < 0.001). Fatty hilum could be visualized in only 2.7% of the nodes with a long axis smaller than 3 mm. Conclusion IMLN is a frequent finding on breast MRI. We have shown that benign IMLNs might be large sized in specific cases like patients with breast implants. When small sized (<= 3mm), they are more likely to be rounded (1/S ratio <2). The fatty hilum that is a feature of benignity might not be visualized in nodes less than or equal to3mm.

    Is Tamoxifen Use a Factor Affecting Continence in Breast Cancer Patients?

    Introduction: Tamoxifen treatment has been shown to reduce the recurrence and mortality rates in hormone receptor-positive breast cancers independent from chemotherapy. This benefit increases with the prolongation of the use of tamoxifen but with increasing side effects. In this study, we aim to evaluate the presence of urogenital symptoms in breast cancer patients on tamoxifen and compare them with those who are not on any hormonotherapy. Materials and methods: This study was performed on patients diagnosed as early-stage breast cancer. The study group consisted of hormone receptor-positive patients given tamoxifen as adjuvant hormonal therapy. The control group consisted of breast cancer patients who had no hormonotherapy. Patients with a complaint of urinary incontinence with onset after tamoxifen usage were evaluated with Urogenital Distress Inventory Short Form (UDI-6), Incontinence Impact Questionnaire Short Form (IIQ-7) and Incontinence Quality of Life Questionnaire (IQOL). Results: A total of 137 early-stage breast cancer patients were included in this study; 74 estrogen receptor-positive patients on tamoxifen therapy (study group) and 63 hormone receptor-negative patients with no hormonotherapy (control group). The median age was 44 (30-65) years for tamoxifen users and 49 (27-64) years for the control group. The stages of the patients were similar for both groups. 78.4% of the women in the tamoxifen group and 49.2% in the control group were in the premenopausal period. The groups were similar in regard to body mass index and parity. The complaint of urinary incontinence was more frequent in the study group compared to controls (39 (52.7%) vs. 5 (7.9%)). Women with the complaint of urinary incontinence were evaluated with self-reported UDI-6, IIQ-7 and I-QOL forms and the scores were similar for both study and control groups. A statistically significant relation was observed between cigarette smoking and the presence of urinary incontinence. The percentages of smokers were 50% of those with incontinence and 24.7% of those without incontinence. Conclusion: Urinary incontinence is positively correlated with tamoxifen usage in early-stage breast cancer patients.
