Background Breast-conserving therapy is defined as a breast-conserving wide local excision (WLE) of a mammary tumour combined with postoperative radiotherapy. Immediate restoration of the mammary shape by use of breast reduction techniques (volume displacement) or tissue replacement techniques (volume replacement) is gaining popularity to prevent breast malformation. Methods To date, using the internal mammary artery perforator (IMAP) flap has been suggested for immediate volume replacement after WLE, but has never been evaluated in a published study. Results We applied this flap in 12 women (mean age, 56.1 years) after WLE (mean specimen weight, 46.5 g) of the medial aspect of the breast. Over a median follow-up of 35.3 months (standard deviation, 1.2 months), 4 women needed repeated surgery for dog-ear correction of the donor site. Conclusions In our experience, the use of an IMAP flap was a reliable technique with good cosmetic outcomes after oncoplastic reconstruction. In this series, donor site revision often proved necessary initially, but we showed that this may easily be prevented.

Objective: In this study, we evaluated the toxicity and clinical efficacy of nivolumab, a programmed cell death protein 1 (PD-1) inhibitor, on patients with platinum resistant ovarian cancer.Methods: Every second week, 18 patients with platinum resistance ovarian cancer received nivolumab until disease progression occurred. We assessed toxicity, disease control rate, progression free survival (PFS) and overall survival (OS). Radiological response evaluation according to irRECIST was performed every 12th week, while clinical evaluation was done every second week. Results: The disease control rate was 44% (95% confidence interval [CI]=19–87) as 8 showed stable disease, 6 showed progressive disease and 4 died before the first radiological response evaluation. The median OS was 30 weeks (95% CI=14–42; range, 3–95), and PFS was 15 weeks (95% CI=13–17). The median follow-up time was 30 weeks (range, 3–123). The rate of grade 2–5 adverse events was 28% (5 out of 18). Two patients (11%) developed grade 2 and 3 adverse events, respectively, while no grade 4 events were observed. One patient died from intestinal perforation, believed to be caused by concomitant bevacizumab rather than nivolumab. Conclusion: This study shows few adverse events, and promising clinical efficacy when using nivolumab for ovarian cancer.
