Concurrent endocrine therapy with chemotherapy had a concern of potential antagonism. However, gonadotropin-releasing hormone (GnRH) agonist has been used concurrently with chemotherapy to prevent premature ovarian failure for young breast cancer patients. The aim of this study was to determine the impact of concurrent use of GnRH agonists on relapse-free and overall survival, and to establish the oncologic safety of ovarian protection with GnRH agonists. ⋯ Ovarian protection using GnRH agonists can be safely considered for young women with breast cancer in terms of oncologic outcomes. Further studies are needed to assess the long-term outcomes of concurrent GnRH agonist use with chemotherapy.

Diagnosis of breast cancer in young women poses a threat to fertility. Due to a recent trend of delaying pregnancy, an increasing number of breast cancer patients in reproductive age wish to bear children. Health care providers have the responsibility to know how to manage fertility issues in cancer survivors. ⋯ The choice of the suitable strategy depends also on age, type of chemotherapy, partner status and patients' motivation. Various options are available, some established such as embryo and oocyte cryopreservation, some still experimental such as ovarian tissue cryopreservation and ovarian suppression with GnRHa during chemotherapy. An early referral to a reproductive specialist should be offered to patients at risk of infertility who are interested in fertility preservation.

The aim of the present study was to construct the intra-operative prediction model of non-sentinel lymph node (non-SLN) metastasis in breast cancer patients with SLN metastasis using one-step nucleic acid amplification (OSNA). Of 833 breast cancer patients (T1-T2, N0) who underwent SLN biopsy and had their SLNs examined intra-operatively with the OSNA assay, 161 with SLN metastasis and treated with completion axillary lymph node dissection (cALND) were randomly divided into a training (n = 81) and a validation (n = 80) cohort. ⋯ Its diagnostic accuracy (AUC of ROC curve) was 0.809 and 0.704 for the training and validation cohorts, respectively. The intra-operative prediction model using OSNA may have a diagnostic accuracy of non-SLN metastasis comparable to that of the conventional, post-operative prediction model, indicating that it might help decide the indication for cALND.

This study was performed to determine the risk of tumor recurrence after local excision alone in patients with small size (≤1 cm) ductal carcinoma in situ (DCIS) of the breast. We have treated 107 patients who had DCIS measuring ≤1 cm with margin widths of ≥0.3 cm with excision alone per institutional protocol. With a median follow-up time of 58 months, 4 patients developed ipsilateral breast tumor recurrence (IBTR). ⋯ The 5-year rate of IBTR was 6.1%. The patients with resection margin of <1.0 cm had significantly higher rate of IBTR than the patients with resection margin of ≥1.0 cm (23.1% vs. 1.5% at 5-year, p < 0.01). In conclusion, radiotherapy is necessary in the patients with resection margin of <1.0 cm after excision alone because of the substantial risk of IBTR.

There are around 40,000 healthcare applications (apps) available for smartphones. Apps have been reviewed in many specialties. Breast cancer is the most common malignancy in females with almost 1.38 million new cases a year worldwide. Despite the high prevalence of breast disease, apps in this field have not been reviewed to date. We have evaluated apps relevant to breast disease with an emphasis on their evidence base (EB) and medical professional involvement (MPI). ⋯ There is a lack of EB and MPI in the development of current breast apps. Safety concerns highlight the need for regulation, full authorship disclosure and clinical trials. A robust framework for identifying high quality applications is necessary. This will address the current barrier pertaining to a lack of consumer confidence in their use and further aid to promote their widespread implementation within healthcare.
