Breast implant-associated anaplastic large cell lymphoma: a case report and literature review.

UNLABELLED: Breast implant-associated anaplastic large cell lymphoma (ALCL) is a rare new clinical entity. The incidence is 0.3 % per 100,000 women per year. Patients present with non-specific implant-related complications resulting in delayed diagnosis. We present such a case to raise awareness and discuss management. A 48-year-old female presented with a 3-month history of left breast pain and swelling. She had undergone multiple bilateral augmentations 8 years previously. Triple assessment revealed a seroma, and a magnetic resonance imaging scan excluded implant rupture. Cytology showed a typical cells with mitotic activity which lead to removal of implants and a left capsulectomy. Final histology revealed an anaplastic lymphoma kinase (ALK) negative ALCL confined to the capsule. A computerised tomography scan and bone marrow biopsy excluded systemic disease, but due to later identified B symptoms, she received CHOP chemotherapy under the care of the haematologists. ALK-negative ALCL is associated with breast implants, and any persistent late onset seroma or breast symptoms should raise the suspicion of ALK-negative ALCL as a differential diagnosis. The recommended treatment is surgical removal of the implant including a full capsulectomy, highlighting the suspicion of ALCL to the pathologist. Exclusion of systematic disease is also recommended in all patients, and the need for adjuvant therapy should be addressed on an individual case basis. For disease confined to the capsule, adjuvant chemoradiotherapy is not needed. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Malignant phyllodes tumour of the breast mimicking endometriosis.

A 63-year-old woman presented with a clinically malignant mass. Core biopsy showed features resembling endometriosis. The glands were GATA3 and oestrogen receptor positive consistent with mammary origin and had no myoepithelial layer. The excision also showed a fibroepithelial component with stromal overgrowth, frequent mitoses and invasive margin consistent with a malignant phyllodes tumour. KMT2D and SETD2 mutations were present in both the conventional phyllodes tumour and endometriosis-like areas and are also described in endometriosis raising interesting questions about these lesions. This unusual pattern is a potential diagnostic pitfall, so it is helpful to be aware of it.

A meta-analysis of consanguinity and breast cancer.

BACKGROUND: There have been various publications stating that consanguinity both increases and decreases the risk of breast cancer. AIMS: The objective of this study was to determine the impact of consanguinity upon breast cancer. We conducted a systematic review of the literature and meta-analysis. METHODS: Eligible studies were identified on Medline and EMBASE updated to the 19 of September 2017. Studies with sufficient comparative data were included in a meta-analysis. Analyses were carried out using RevMan software. RESULTS: Three comparative studies with a total of 317 individuals with breast cancer and 1459 controls. Reviewing the literature demonstrated conflicting conclusions of the influence of consanguinity upon breast cancer. The meta-analysis showed that there were no statistically significant associations between consanguinity and breast cancer though there was a trend protection from a history of consanguinity. CONCLUSION: Though there is limited literature published on the effects of parental consanguinity, the available data does not demonstrate that it is a risk factor for breast cancer.

Dexamethasone reduces emesis after major gastrointestinal surgery (DREAMS).

BACKGROUND: Postoperative nausea and vomiting is one of the most common complications affecting patients after surgery and causes significant morbidity and increased length of hospital stay. It is accepted that patients undergoing surgery on the bowel are at a higher risk. In the current era of minimally invasive colorectal surgery combined with enhanced recovery, reducing the incidence and severity of postoperative nausea and vomiting is particularly important. Dexamethasone is widely, but not universally used. It is known to improve appetite and gastric emptying, thus reduce vomiting. However, this benefit is not established in patients undergoing bowel surgery, and dexamethasone has possible side effects such as increased risk of wound infection and anastomotic leak that could adversely affect recovery. DESIGN: DREAMS is a phase III, double-blind, multicenter, randomized controlled trial with the primary objective of determining if preoperative dexamethasone reduces postoperative nausea and vomiting in patients undergoing elective gastrointestinal resections. DREAMS aims to randomize 1,350 patients over 2.5 years.Patients undergoing laparoscopic or open colorectal resections for malignant or benign pathology are randomized between 8 mg intravenous dexamethasone and control (no dexamethasone). All patients are given one additional antiemetic at the time of induction, prior to randomization. Both the patient and their surgeon are blinded as to the treatment arm.Secondary objectives of the DREAMS trial are to determine whether there are other measurable benefits during recovery from surgery with the use of dexamethasone, including quicker return to oral diet and reduced length of stay. Health-related quality of life, fatigue and risks of infections will be investigated. TRIAL REGISTRATION: ISRCTN21973627.
