PURPOSE We evaluated the effect of Internet-based cognitive behavioral therapy (iCBT), with or without therapist support, on the perceived impact of hot flushes and night sweats (HF/NS) and overall levels of menopausal symptoms (primary outcomes), sleep quality, HF/NS frequency, sexual functioning, psychological distress, and health-related quality of life in breast cancer survivors with treatment-induced menopausal symptoms. PATIENTS AND METHODS We randomly assigned 254 breast cancer survivors to a therapist-guided or a self-managed iCBT group or to a waiting list control group. The 6-week iCBT program included psycho-education, behavior monitoring, and cognitive restructuring. Questionnaires were administered at baseline and at 10 weeks and 24 weeks postrandomization. We used mixed-effects models to compare the intervention groups with the control group over time. Significance was set at P < .01. An effect size (ES) of .20 was considered small, .50 moderate and clinically significant, and .80 large. RESULTS Compared with the control group, the guided and self-managed iCBT groups reported a significant decrease in the perceived impact of HF/NS (ES, .63 and .56, respectively; both P < .001) and improvement in sleep quality (ES, .57 and .41; both P < .001). The guided group also reported significant improvement in overall levels of menopausal symptoms (ES, .33; P = .003), and NS frequency (ES, .64; P < .001). At longer-term follow-up (24 weeks), the effects remained significant, with a smaller ES for the guided group on perceived impact of HF/NS and sleep quality and for the self-managed group on overall levels of menopausal symptoms. Additional longer-term effects for both intervention groups were found for hot flush frequency. CONCLUSION iCBT, with or without therapist support, has clinically significant, salutary effects on the perceived impact and frequency of HF/NS, overall levels of menopausal symptoms, and sleep quality.

Most patients with locally recurrent breast cancer undergo axillary lymph node dissection (ALND). However, repeat sentinel node biopsy (SNB) could provide regional nodal staging and obviate the need for standard ALND. The Sentinel Node and Recurrent Breast Cancer (SNARB) study is a Dutch nationwide registration study conducted to determine feasibility, aberrant drainage rates, and clinical consequences of repeat SNB. A total of 536 patients with locally recurrent non-metastatic breast cancer underwent lymphatic mapping and repeat SNB in 29 Dutch hospitals. A repeat sentinel node (SN) was identified in 333 of 536 patients (62.1 %) and surgically harvested in 287 patients (53.5 %). Aberrant lymph drainage was observed in 180 (54.1 %) of the 333 patients, more often after previous ALND (81.9 %) than SNB (28.4 %; P < 0.001). In 230 patients (80.1 %), the retrieved SN was tumor negative; 17 SNs (5.9 %) contained a micrometastasis and 29 (10.1 %) a macrometastasis. Confirmation ALND in 31 repeat SN-negative patients revealed a macrometastasis in two patients (6.5 %). The negative predictive value (NPV) of repeat SNB was 93.6 %, and ALND was omitted in 109 of the 248 patients (44.0 %) with a negative repeat SN. In 29 of the 44 patients (63.0 %) with a positive SN, adjuvant treatment plans were altered based on the repeat SNB. Repeat SNB is a feasible procedure with a high NPV, leading to a change in management in a substantial proportion of patients. Therefore, repeat SNB should replace routine ALND and serve as the standard of care in recurrent breast cancer.
