Prostate-specific membrane antigen (PSMA) PET CT is widely used for staging and restaging of prostate cancer. Thyroid and other non-prostatic pathology may be incidentally identified by this imaging modality. Such findings warrant further investigation given their malignant potential.

Background: Metastatic cutaneous squamous cell carcinoma to the axilla is uncommon, with limited data to guide management. We sought to assess the outcomes of patients with this condition after surgery and radiotherapy.

Methods: A retrospective cohort study of patients treated at two Australian hospitals from 1994 through 2016 was performed.

Background: Although microscopic positive margins appear to have no independent prognostic impact in papillary thyroid cancer (PTC), this may not be the case in pT4a tumors.

Methods: Retrospective analysis of 610 patients with PTC, 39 with pT4a tumors, to determine if microscopic positive margins impact disease-free survival (DFS) in pT4a PTC.

Results: On univariate analysis, microscopic positive margins were not associated with reduced DFS in patients with no extrathyroidal extension (ETE) (hazard ratio [HR], 1.

Background: The prognostic significance of microscopic positive margins in papillary thyroid carcinoma (PTC) remains unclear. The aim of this study was to determine if microscopic positive margins are associated with increased risk of disease recurrence.

Methods: This is a retrospective analysis of 610 patients with PTC using multivariate Cox regression to evaluate the association between microscopic positive margins and disease-free survival.

Background: Esophageal and gastroesophageal junctional (GEJ) adenocarcinoma is one of the most fatal cancers and has the fastest rising incidence rate of all cancers. Identification of biomarkers is needed to tailor treatments to each patient's tumor biology and prognosis.

Methods: Gene expression profiling was performed in a test cohort of 80 chemoradiotherapy (CRTx)-naïve patients with external validation in a separate cohort of 62 CRTx-naïve patients and 169 patients with advanced-stage disease treated with CRTx.

Background: Robot-assisted general surgery operations are being performed more frequently. This review investigates whether robotic assistance results in significant advantages or disadvantages for the operative treatment of gastro-oesophageal reflux disease and achalasia.

Methods: The electronic databases (Medline, Embase, PubMed) were searched for original English language publications for antireflux surgery and Heller's myotomy between January 1990 and December 2013.

Background: Robot-assisted surgery is a technically feasible alternative to open and laparoscopic surgery, which is being more frequently used in general surgery. We undertook this review to investigate whether robotic assistance provides a significant benefit for oesophagogastric cancer surgery.

Methods: Electronic databases were searched for original English-language publications for robotic-assisted gastrectomy and oesophagectomy between January 1990 and October 2013.

The aim of this study was to compare the management and outcome of acute cholecystitis in an acute care surgery (ACS) model to that of the traditional home-call attending surgeon. The ACS model is one in which a consultant led team manage all emergency surgical presentations. The consultant is involved with every decision made including theatre allocation.
