BACKGROUND AND OBJECTIVE: Nonmelanoma skin cancer (NMSC) is the most common human cancer. Because these tumors often affect the face, there is a strong need for both accurate removal of these neoplasms to prevent recurrence and maximal tissue preservation to prevent cosmetic or functional deformity. Polarization-enhanced reflectance and fluorescence imaging (PERFI) is a new bedside method that uses fluorescent chromophores to image NMSC. While the feasibility of the technique has been successfully demonstrated in ex vivo studies, this is the first pilot study to extend the use of PERFI to in vivo intraoperative imaging of NMSC...

For years, lobular carcinoma In Situ (LCIS) has been considered a high-risk marker for developing breast cancer. It is well known that ductal carcinoma In Situ is a precursor for the development of invasive ductal carcinoma, and ductal carcinoma In Situ is reported to be present in invasive ductal carcinoma in at least 40 per cent of cases. A similar relationship between LCIS and invasive lobular carcinoma (ILC) remains in question. This study evaluates the incidence of synchronous LCIS and ILC at our institution...

Olfactory neuroblastoma (ONB) is a potentially curable disease, despite being an aggressive malignancy with a poor natural history. Our goal was to evaluate management outcomes for patients with ONB treated at our institution. Our prospective database for brain tumors and the pathology registry of head and neck cancers at Oslo University Hospital were searched to identify all patients treated for ONB between 1998 and 2016. Variables extracted from these databases, supplemented by retrospective chart reviews, underwent thorough analysis...

BACKGROUND: By providing tumor-free margins, Mohs micrographic surgery (MMS) results in high cure rates in the treatment of nonmelanoma skin cancers (NMSCs). However, when closure of the post-MMS defect is coordinated with reconstructive surgery, redundant tissue is sometimes submitted for permanent section evaluation. OBJECTIVE: The purpose of our study was to investigate the frequency and effect of this practice. MATERIALS AND METHODS: Patients (12 years and older) with NMSCs cleared by MMS with coordinated closures from 2014 to 2016 were identified...

Objective To compare the surgical outcomes between resection and enucleation in robot-assisted laparoscopic partial nephrectomy (RAPN) based on the Surface-Intermediate-Base margin score (SIB score). Patients and Methods This study included 282 patients who underwent RAPN between 2014 and 2016. SIB score was macroscopically evaluated immediately after the surgery. We divided the patients into the following two groups: enucleation (SIB score, 1-2) and resection (SIB score, 3-5). To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) often infiltrates to the adjacent major vasculatures; however, direct invasion of PDAC to the inferior vena cava (IVC) is uncommon. CASE PRESENTATION: We report our experience with three cases of PDAC directly invading the IVC wall. All three patients underwent pancreatoduodenectomy along with wedge resection of the IVC wall without severe postoperative complications. Histopathological studies revealed tumor infiltration to the adventitia of the IVC...

We conducted this study to determine whether the methylation status of the O(6)-methylguanine-DNA methyltransferase (MGMT) promoter was a prognostic marker for positive outcomes of gamma knife radiosurgery (GKS) for recurrent glioblastoma (GBM). We retrospectively examined 61 patients, who underwent GKS for local recurrent GBM between 2004 and 2015; in all patients, the methylation status of the MGMT promoter was identified via methylation-specific quantitative real-time polymerase chain reaction. All patients underwent surgical resection and were diagnosed histopathologically with GBM...

Well-differentiated liposarcomas of the extremities are one of the most frequent types of malignant soft tissue tumors in adults. These tumors are typically locally aggressive and show a tendency to recurrence after surgical excision even though they do not metastasize and very rarely dedifferentiate. Its clinical presentation is generally a progressively growing mass causing aesthetic, functional, or compressive symptoms depending on the tumor's size and localization. Several authors recommend a wide excision with free margins in order to minimize the risk of recurrence, while others report good results and a low rate of recurrence with more conservative or even marginal excision thereby avoiding complications due to surgical site morbidity...

REVIEW
Janis Spigulis
Optical tissue imaging has several advantages over the routine clinical imaging methods, including non-invasiveness (it does not change the structure of tissues), remote operation (it avoids infections) and the ability to quantify the tissue condition by means of specific image parameters. Dermatologists and other skin experts need compact (preferably pocket-size), self-sustaining and easy-to-use imaging devices. The operational principles and designs of ten portable in-vivo skin imaging prototypes developed at the Biophotonics Laboratory of Institute of Atomic Physics and Spectroscopy, University of Latvia during the recent five years are presented in this paper...

Rectal cancer is one of the common cancers which poses a threat to the health of mankind. In recent years. Multi-modality treatment strategies for locally advanced rectal cancer improve the treatment efficiency. Accurate prediction of the treatment response after the neoadjuvant chemoradiotherapy (CRT) can guide more suitable treatment strategy. MERCURY study proved the prognostic value of post-CRT standard morphologic MRI(T2-weighted) assessment of tumor regression grade(TRG), and MRI assessment of circumferential resection margin can guide the definitive surgery...
