The optimal management of patients with resection line involvement after endoscopic or surgical treatment for gastric cancer is debated. In contrast to previous reports, we examined both the experience of endoscopists and surgeons in early-stage lesions and the wide variation in treatments proposed for advanced disease in case of infiltration of resection margins. A PubMed search for papers using the key words: gastric or stomach cancer, or Carcinoma; gastrectomy and positive margins; surgical margins or resection line or endoscopic margin involvement; and R1 resection, from January 2000 to July 2015 was undertaken...

BACKGROUND: For focal radiofrequency ablation of Barrett's oesophagus, a simplified regimen (3 × 15 J/cm2 , without cleaning) has proven to be as effective as the standard regimen (2 × 15 J/cm2 , followed by cleaning, followed by 2 × 15 J/cm2 ). However, this simplified regimen seemed to be associated with a higher stenosis rate. Therefore, we lowered the radiofrequency energy and hypothesised that this new simplified regimen would be as effective and safe as the standard regimen...

INTRODUCTION: The recommended pathological resection margin (8 mm) for vulvar squamous cell carcinoma (SCC) is broader than for SCC located elsewhere, and does not depend on tumor grade or lesion size. Our aim is to evaluate the resection margin in vulvar SCC in relation to local recurrence, and to determine the impact of other prognostic factors. MATERIALS AND METHODS: Data of all surgically treated patients at the Gynecological Oncology Center South with vulvar SCC, FIGO IB-IIIC, between 2005 and 2015 were analysed retrospectively...

Liver transplantation (LT) is one of the most effective treatments for end-stage liver disease caused by related risk factors when liver resection is contraindicated. Additionally, despite the decrease in the prevalence of hepatitis B virus (HBV) over the past two decades, the absolute number of HBsAg-positive people has increased, leading to an increase in HBV-related liver cirrhosis and hepatocellular carcinoma. Consequently, a large demand exists for LT. While the wait time for patients on the donor list is, to some degree, shorter due to the development of living donor liver transplantation (LDLT), there is still a shortage of liver grafts...

OBJECTIVE: The objective of this study was to compare the prognoses of patients with low- and high-risk rectal cancer detected by MRI who were treated without neoadjuvant chemoradiotherapy (NCRT) and to determine independent risk factors. MATERIALS AND METHODS: This retrospective study included 185 patients with pathologically proven rectal adenocarcinoma who were treated without NCRT. Cancer was defined as high risk if one or more of the following factors were present: extramural depth of tumor invasion greater than 5 mm or stage T4a or T4b for tumor in the mid or high rectum; involvement of intersphincteric space, levators, or adjacent organs for tumor in the low rectum; extramural venous invasion (EMVI); or circumferential resection margin (CRM) involvement...

RATIONALE: Testicular Leydig cell tumor (LCT) is a rare neoplasm. It commonly presents as a painless testicular mass with or without endocrine changes. Histological and immunohistochemical examination play important roles in differentiating LCT from testicular germ cell tumors. PATIENT CONCERNS: We highlight the imaging phenotype, as well as the pathological findings of a case of LCT in a 62-year-old male. DIAGNOSES: Preoperative noncontrast CT scan of the abdomen revealed a 7...

Deletions of chromosome arm 13q belong to the most frequent molecular alterations in prostate cancer. To better understand the role of 13q deletion in prostate cancer we took advantage of our large prostate cancer tissue microarray comprising more than 12,000 cancer samples with full pathological and clinical follow up data. Fluorescence in situ hybridization with probes for ENOX1 (13q14.11) and the retinoblastoma gene (RB1, 13q14.2) was employed. A 13q deletion was found in 21% of 7,375 analyzable cancers...

AIM: Recent studies focused on rectal cancer suggested that a 3D imaging segmentation obtained from MRI data could contribute in the definition of the circumferential resection margin (CRM) and in the assessment of the tumor regression following neo-adjuvant treatments. Here, we propose a method for defining and visualizing the circumferential margins using 3D MRI segmentation; this methodology was tested in a clinical study comparing 3D CRM assessment vs standard MRI imaging. PATIENTS AND METHODS: MRI scans performed before neo-adjuvant treatments were selected and reviewed...

BACKGROUND: Low Rectal Anterior Resection (LAR) is challenging when anal canal mucosa and/or internal sphincter are involved by very low tumors. In these cases, Intersphincteric resection (ISR) with the removal of the internal sphincter is designed to increase the distal margin of resection, thus preserving the external sphincter and pubo-rectalis muscle complex. Aim is to compare results after ISR with those of LAR, including subgroup analysis of open, laparoscopic and robotic ISR. METHODS: Studies published from January 1991 to January 2017 describing ISR and comparing results with LAR in adults were included irrespective of the technique...

An endolymphatic sac tumor (ELST) is a rare, indolent but locally aggressive tumor arising in the posterior petrous ridge. Patients present with sensorineural hearing loss and tinnitus. As the tumor progresses, patients may experience vertigo, ataxia, facial nerve paresis, pain and otorrhea. Most patients present in their 4th or 5th decade with a wide age range. Patients with von Hippel-Lindau disease have an increased likelihood of developing ELST. Histologically, ELST is a low-grade adenocarcinoma. As it progresses, it destroys bone and extends into adjacent tissues...

Stage I non-small cell lung cancer (NSCLC) is a localized disease without metastasis; therefore, it can be treated effectively with local therapies. Pulmonary resection is the most frequent treatment, performed as pulmonary wedge resection, segmentectomy, lobectomy, or pneumonectomy. Some retrospective clinical studies of pulmonary wedge resection suggest that its outcome may be inferior to that of anatomical pulmonary resection, whereas other recent studies, which assess surgical margin status, leveled acceptable outcomes...

BACKGROUND: Laparoscopic subtotal gastrectomy (LsTG) has several advantages, including technical safety and preservation of postoperative function, compared with total or proximal gastrectomy for early gastric cancer. However, LsTG has some technical issues with respect to achieving a safe resection margin and patency in patients with lesions close to the cardia or fornix. When LsTG is performed for lesions located rather close to the cardia or fornix, conventional marking clips can physically hinder transection by an endoscopic linear stapler...

Background: Repair of blepharoptosis from the posterior eyelid approach has usually been done utilizing a Müller's muscle-conjuctival resection (MMCR) or an "open sky" technique. We present a new technique to advance the levator muscle from the posterior-approach in a closed fashion that can be used in patients with severe involutional ptosis. Methods: A retrospective chart review was performed for consecutive patients with severe involutional blepharoptosis during a 6-year period treated by a single surgeon with a Closed Posterior Levator Advancement...

Introduction: Cecal duplication is a rare congenital anomaly and to the best of our knowledge, only 43 cases have been reported in the literature till date. Most of them present within the first year of life. They can mimic intussusception, and the delay in diagnosis can lead to high morbidity. Case report: A five-year boy presented with pain abdomen for a week. He was found to have ileocolic intussusception. The intussusception could only be partially reduced by the hydrostatic method...

This is the second-largest retrospective analysis addressing the controversy of whether adult rhabdomyosarcoma (RMS) should be treated with chemotherapy regimens adopted from pediatric RMS protocols or adult soft-tissue sarcoma protocols. A comprehensive database search identified 553 adults with primary non-metastatic RMS. Increasing age, intermediate-risk disease, no chemotherapy use, anthacycline-based and poor chemotherapy response were significant predictors of poor overall and progression-free survival...

BACKGROUND: A tumor composed exclusively or predominantly of human melanin black 45 (HMB45)-positive epithelioid cells is called a perivascular epithelioid cell tumor (PEComa). We report a very rare case of a PEComa of the greater omentum. CASE PRESENTATION: MRI conducted to examine the orthopedic disease of the patients, a 49-year-old Japanese woman, also identified a tumor in her pelvis. A CT scan revealed a tumor mass on the right side of the pelvic floor and clear nutrient vessels originating from the splenic and celiac arteries...

AIM: Pelvic exenteration surgery remains the only curative option for recurrent rectal cancer. Microscopically involved surgical margins (R1) are associated with a higher risk of local recurrence and decreased survival. Our study aimed to develop a post hoc multidisciplinary case conference review and investigate its potential for identifying areas for improvement. METHOD: Patients who underwent pelvic exenteration surgery for recurrent rectal cancer with R1 resections at a tertiary referral center between April 2014- January 2016 were retrospectively reviewed from a prospectively maintained database...

OBJECTIVE: To compare the quality of surgical resection of transanal total mesorectal excision (TA-TME) and robotic total mesorectal excision (R-TME). BACKGROUND: Both TA-TME and R-TME have been advocated to improve the quality of surgery for rectal cancer below 10 cm from the anal verge, but there are little data comparing TA-TME and R-TME. METHODS: Data of patients undergoing TA-TME or R-TME for rectal cancer below 10 cm from the anal verge and a sphincter-saving procedure from 5 high-volume rectal cancer referral centers between 2011 and 2017 were obtained...

PURPOSE: Laparoscopic liver resection is increasingly used to treat patients with hepatic tumor. However, during laparoscopic resection, information obtained by palpation using laparoscopic forceps or from intraoperative ultrasonography is extremely limited, which may pose a risk for positive surgical margins. This study aimed to investigate the feasibility and clinical application of near-infrared (NIR) fluorescence imaging to guide laparoscopic liver resection of a liver tumor and secure the surgical margins...
