Resection is the gold standard in the treatment of liver metastases from colorectal cancer. An internal cooled radiofrequency electrode was described to achieve tissue coagulation to a greater margin width. The aim of this study is to determinate if a RF-assisted transection device (RFAT) has any effect on local hepatic recurrence (LHER) compared to conventional technologies. A study population of 103 patients who had undergone a hepatic surgical resection was retrospectively analysed. Patients were classified into two groups according to the device used: a RF-assisted device (RFAT group; n = 45) and standard conventional devices (control group; n = 58)...

BACKGROUND: Bacillus Calmette-Guérin (BCG) is the most effective initial intravesical therapy for high-grade non-muscle invasive bladder cancer, but many patients still fail. Combination intravesical BCG and interferon (IFN) will salvage some patients but results remain suboptimal. OBJECTIVE: We hypothesized that further immunostimulation with intravesical interleukin-2 and subcutaneous granulocyte-macrophage colony-stimulating factor may improve response to intravesical BCG and IFN in patient with prior BCG failure(s)...

INTRODUCTION: There is a lack of validated quality metrics to evaluate the care of patients receiving surgery for renal cell carcinoma (RCC). To address this, the Kidney Cancer Research Network of Canada defined a list of quality indicators (QI) to assess hospital-level performance. We have case-mix adjusted these QIs to benchmark RCC surgical care at Canadian academic centres. METHODS: The Canadian Kidney Cancer information system (CKCis) was used to measure six QIs: laparoscopic approach proportion (LA), partial nephrectomy proportion (PN), partial nephrectomy in patients with chronic kidney disease (CKDPN), positive margin rate (PMR), partial nephrectomy complication rate (PNCx), and warm ischemia time (WIT)...

BACKGROUND: Primary adenoid cystic carcinoma (ACC) of the breast is a rare subtype of invasive breast cancer. It has a particular interest because of its excellent prognosis conversely to other triple-negative breast cancers that are associated with poor prognosis. The place of chemotherapy and radiotherapy remains controversial and there is no consensus on optimal management of the ACC of the breast. CASE REPORT: A 50-year-old woman, presented with a palpable right breast lump...

BACKGROUND: Minimally invasive surgery (MIS) has been widely adopted for common operations in pediatric surgery; however, its role in childhood tumors is limited by concerns about oncologic outcomes. We compared open and MIS approaches for pediatric neuroblastoma and Wilms tumor (WT) using a national database. METHODS: The National Cancer Data Base from 2010 to 2012 was queried for cases of neuroblastoma and WT in children ≤21 years old. Children were classified as receiving open or MIS surgery for definitive resection, with clinical outcomes compared using a propensity matching methodology (two open:one MIS)...

Previous studies have demonstrated that elevated yes‑associated protein (YAP) expression is associated with tumor aggression and poor prognosis in various types of human cancer. However, the clinicopathological significance and the prognostic value of YAP in laryngeal squamous cell carcinoma (LSCC) is unknown. The aim of the present study was to identify the expression pattern and prognostic significance of YAP in patients with LSCC. YAP mRNA and protein expression levels were examined in fresh and archived LSCC samples using the reverse transcription‑quantitative polymerase chain reaction, immunohistochemistry (IHC) and western blotting...

BACKGROUND: Within the last two decades, surgical treatment of colorectal cancer has changed dramatically from large abdominal incisions to minimal access surgery. In the recent years, single port (SP) surgery has spawned from conventional laparoscopic surgery. The purpose of this study was to compare conventional with SP laparoscopic abdominoperineal resection (LAPR) for rectal cancer. PATIENTS AND METHODS: This was a single-center non-randomised retrospective comparative study of prospectively collected data on 53 patients who underwent abdominoperineal resection for low rectal cancer; 41 with conventional laparoscopy and 12 with SP surgery...

In the modern era, a pathology report of thyroid carcinoma requires the inclusion of numerous prognostically relevant histopathologic features, e.g. the presence and extent of vascular and capsular invasion, extrathyroidal extension, the surgical margin status, and the characteristics of nodal metastasis. These pathologic features are crucial components of the initial risk stratification to determine the need for completion thyroidectomy and/or post-operative radioactive iodine ablation therapy. The current review aims to summarize the diagnostic criteria, the controversies, the prognostic impacts, and the challenges of these pathologic characteristics, focusing specifically on the parameters that are incorporated into the American Joint Committee on Cancer (AJCC) staging system, College of American Pathologists (CAP) reporting template, American Thyroid Association (ATA), and National Comprehensive Cancer Network (NCCN) guidelines...

REVIEW
H-R Raab
R1 resections in rectal cancer particularly affect the circumferential resection margin (CRM) and lead to increased local recurrence rates, more distant metastases and a poorer prognosis. The proximity of the tumor to the CRM is already sufficient to increases these risks; therefore, according to the guidelines, it is now necessary to distinguish between R0 wide (≥1 mm distance), R0 close (<1 mm) and R1. The surgical technique is decisive for avoiding R1 situations. The preparation follows the boundary layers and envelope fascia in a standardized radical way and if necessary deviates away from these structures and the tumor under en bloc resection of neighboring structures...

BACKGROUND: Accurate intraoperative localization of esophageal lesions is essential for successful surgical resection. We tested whether preoperative endoscopic placement of titanium clips could facilitate intraoperative localization of early-stage esophageal cancer or severe dysplasia. METHODS: A prospective randomized clinical trial was performed between May 2012 and July 2014. All enrolled patients received preoperative endoscopy and esophageal endoscopic ultrasound, as well as pathological study on the biopsy specimen, to confirm early stage esophageal cancer or severe dysplasia...

Here, we used an informatics-based approach to identify novel biomarkers of overall survival and tumor progression in non-small cell lung cancer (NSCLC) patients. We determined whether nuclear-encoded genes associated with mitochondrial biogenesis and function can be used to effectively predict clinical outcome in lung cancer. This strategy allowed us to directly provide in silico validation of the prognostic value of these mitochondrial components in large, clinically-relevant, lung cancer patient populations...

BACKGROUND: Wire-localized excision of nonpalpable breast cancer is imprecise, resulting in positive margins 25-30% of the time. METHODS: Patients underwent preoperative supine magnetic resonance imaging (MRI). A radiologist outlined the tumor edges on consecutive images, creating a three-dimensional (3D) view of its location. Using 3D printing, a bra-like plastic form (the Breast Cancer Locator [BCL]) was fabricated, with features that allowed a surgeon to (1) mark the edges of the tumor on the breast surface; (2) inject blue dye into the breast 1 cm from the tumor edges; and (3) place a wire in the tumor at the time of surgery...
