Recurrent breast carcinoma with brachial plexus involvement is often misinterpreted as a radiation- or chemotherapy-induced brachial plexopathy. We review a case series of 4 patients at our institution within a 1-year period, and describe their diagnostic workup and treatment with a palliative periscapular amputation. Our aim is to describe this entity, indications and benefits of this procedure, when required for progressive disease, with the goal of raising a collective index of suspicion to aid in earlier diagnosis. ⋯ Breast cancer survivors presenting with a brachial plexopathy should raise suspicion for recurrent disease. Close evaluation with MRI is the best first step in diagnosis. Although periscapular amputation is an aggressive surgical treatment, it is an acceptable option when disease has progressed to neurovascular involvement and a functionless limb.

Vascular endothelial growth factor (VEGF) is a prognostic factor and target treatment for metastatic colorectal and ovarian cancer. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has improved survival on peritoneal carcinomatosis (PC) from appendiceal cancer. We hypothesize that tumoral high expression of VEGF receptor 2 (VEGFR-2) is a negative prognostic factor for survival in patients with PC from appendiceal cancer. ⋯ There is a trend towards better outcomes and survival in patients with PC from appendiceal cancer who have low expression of VEGFR-2 compared to high expression. More studies are encouraged to confirm this trend.

Peritoneal carcinomatosis (PC) from gastric cancer is a condition with a very bleak prognosis. Most authors consider it to be a terminal disease and recommend palliative therapy only. Multimodal therapeutic approaches to PC have emerged in the last decades, combining cytoreductive surgery (CRS) and peritonectomy procedures with perioperative intraperitoneal chemotherapy (IPEC), including hyperthermic intraperitoneal chemotherapy (HIPEC) and/or early postoperative intraperitoneal chemotherapy (EPIC). ⋯ Data supporting beneficial effects once gastric PC is already manifest is scarce and limited to few centres with specific experience in this field. Conversely, with regards to the peritoneal perfusion for preventing PC in high risk gastric cancer patients, there are phase III trials and meta-analysis which support beneficial effects resulting from the HIPEC procedure. To offer a baseline guide, we summarized the actual status and general outcome obtained by this multimodal technique, in association or not with CRS as treatment of advanced GC.

Comparative Study
Concordance between vacuum assisted biopsy and postoperative histology: implications for the proposed Low Risk DCIS Trial (LORIS).
The recent Breast Cancer Screening Review has estimated that for one life saved three patients are overtreated. The dramatic increase in the diagnosis of Ductal carcinoma in-situ (DCIS) has not lead to the expected decrease in the incidence of invasive cancer. It is not clear if all DCIS progress to invasive cancer if untreated. The Low Risk DCIS Trial (LORIS) intends to compare the current treatment of low risk DCIS i.e. surgery, with active monitoring. For effective implementation, concordance between diagnostic biopsy using large volume vacuum assisted biopsy (VAB) and excision histology is vital. A two-centre UK audit was done to assess concordance in patients diagnosed with low grade DCIS diagnosed using VAB. ⋯ The upgrade rates to invasive cancer are comparable to series published in literature. The concordance for the low risk DCIS with zero upgrade to invasive cancer supports the stringent LORIS eligibility criteria for trial selection.

Controlled Clinical Trial
Selective axillary dissection after axillary reverse mapping to prevent breast-cancer-related lymphoedema.
It has recently been reported that, using axillary reverse mapping (ARM), the lymphatics from the arm can be spared to reduce the incidence of breast-cancer-related lymphoedema (BCRL). The aim of this study was to assess the feasibility of selective axillary dissection (SAD) after using ARM and partially preserving arm drainage, and to assess the occurrence of BCRL. ⋯ Using a radioisotope enables an effective and safe SAD in a large proportion of patients. There was evidence of a trend to suggest a learning curve. The rate of BCRL after SAD was less than one third of the rate recorded after ALND, a result that should encourage the development of the former technique.
