The sentinel lymph node dissection (SLND) concept relies on the accurate detection of primary nodal landing sites and could represent a major advancement towards accurate, non-invasive pelvic staging in prostate cancer (PCa). Different iterations of the technique have now been validated and reproduced mostly in large-volume centres. The existing evidence denotes the feasibility and sensitivity of SLND, with encouraging pre- and intraoperative detection rates of 98% and 96%. Yet, current surgical practice mandates a backup template dissection due to a false negative rate, up to 7...

Radiotherapy after lymph node dissection is recommended in high-risk melanoma cases. The aim of this study is to assess whether intensity-modulated radiotherapy (IMRT) offers advantages over three-dimensional conformal radiotherapy (3DCRT) in the groin nodal basin. Fifteen consecutively treated patients (5 3DCRT and 10 IMRT) were selected. Optimized theoretical plans using the other modality were created - enabling direct comparisons of 3DCRT and IMRT. Target volume and organs at risk constraints were assessed as achieved or as having minor (≤5%) or major (>5%) deviations...

A 78-year-old man visited our hospital with a prolapsed hemorrhoid. He was referred to the dermatology unit due to the thickness and redness of the perianal skin. He was diagnosed as having extra mammary Paget's disease by skin biopsy. After a biopsy of the anal polyp was performed to investigate the primary site, he was diagnosed with early anal canal cancer with Pagetoid spread and underwent a radical operation. Abdominoperineal resection with skin(D2 prx D3 lymphadenectomy) was performed with perineal reconstruction using a gracilis muscle graft...

INTRODUCTION: In a distal pancreatectomy combined with a distal gastrectomy, the splenic artery and vein must be conserved. However, it is not easy in pure laparoscopic surgery. We performed a hand-assisted laparoscopic spleen-preserving distal pancreatectomy (HALS-SPDP) combined with a laparoscopic distal gastrectomy (LDG) for the treatment of a pancreatic neuroendocrine tumor (NET) with early gastric cancer. PRESENTATION OF CASE: A 67-year-old male was hospitalized with no complaint...

OBJECTIVE: To identify factors associated with regional recurrence (RR) following lymphadenectomy for penile cancer in order to determine which patients might benefit from adjuvant therapy. MATERIALS/METHODS: Men who underwent lymphadenectomy for penile squamous cell carcinoma from 1977-2014 were identified from an institutional database. Kaplan-Meier curves estimated recurrence-free survival (RFS) calculated from the date of lymphadenectomy. Cox regression models evaluated the association between RFS and patient and tumor characteristics...

OBJECTIVE: Sentinel lymph node (SLN) mapping for endometrial (EC) and cervical cancers (CC) is a current technique that could provide benefits over traditional lymphadenectomy. Near-infrared (NIR) fluorescence imaging is a promising technique to perform this procedure. We conducted a systematic review of the evidence regarding the technique and the effectiveness of indocyanine green (ICG) during SLN biopsy, using robotic and laparoscopic assisted surgery and laparotomy. MATERIALS AND METHODS: We conducted a computer literature search for published English language studies in humans using PubMed since January 2010 up to May 2015...

PURPOSE: Scintigraphic mapping of sentinel lymph node (SLN) is increasingly performed in patients with endometrial carcinoma although its routine clinical use is still under investigation. The purpose of this study was to compare preoperative SLN detection by means of SPECT/CT using pericervical (PC) versus hysteroscopic peritumoral (PT) injection. PATIENTS AND METHODS: One hundred forty consecutive patients with endometrial carcinoma who underwent surgery and preoperative SLN SPECT/CT with Tc-nanocolloid were included...

Primary pulmonary chondrosarcoma is a rare neoplasm that usually grows slowly, metastasizes late, and responds well to excision when localized. Herein, we present a 59-year-old man who manifested with hemoptysis, cough and dyspnea with a hemithorax mass. A chest computed tomography scan demonstrated a fast-growing mass in the right upper lobe, and the enhancement was partially heterogeneous. Bronchoscopy revealed a hemorrhagic neoplasm in the right upper bronchus. A bronchoscopy biopsy specimen revealed a variety of tissues, including mucoid cartilage, fibers, respiratory epithelium and squamous epithelium...

BACKGROUND: The main drawback of central neck lymph node dissection is postoperative parathyroid failure. Little information is available concerning inadvertent resection of the parathyroid glands in this setting and its relationship to postoperative hypoparathyroidism. Our aim was to determine the prevalence of inadvertent parathyroidectomy during total thyroidectomy and central neck dissection for papillary thyroid cancer and its impact on short-and long-term parathyroid function. METHODS: This was a prospective observational study of consecutive patients undergoing first-time total thyroidectomy with a central neck dissection for papillary carcinoma >10 mm...

MELF invasion has been associated with nonvaginal recurrences and lymph node (LN) metastases in multi-institutional case control studies but has not been well examined in large single-institution cohorts. Hysterectomy specimens with FIGO 1 endometrioid endometrial carcinoma and lymphadenectomies from 2007 to 2012 were identified. Electronic medical records and histologic slides were reviewed. Of 464 identified cases, 163 (35.1%) were noninvasive, 60 (12.9%) had MELF, 222 (47.8%) had a component of the infiltrative invasion pattern without MELF, 13 (2...

BACKGROUND: Papillary thyroid carcinoma (PTC) is frequently associated with cervical lymph node metastases. Guidelines recommend performing ultrasound-guided fine-needle aspiration cytology (FNAC) for suspicious nodes to guide management. No specific recommendations are available for the use of FNA thyroglobulin assay (FNA-Tg). This study investigated the diagnostic value of performing FNAC and FNA-Tg. METHODS: Patient demographics, preoperative investigations, surgery, and lymph node pathology were collected for patients with PTC who underwent lateral neck lymphadenectomy and central compartment reexploration from January 2000 to July 2015...

OBJECTIVE: Although surgery in selected small-cell lung cancer (SCLC) patients has been proposed as a part of multimodality therapy, so far, the prognostic impact of node-spreading pattern has not been fully elucidated. To investigate this issue, a retrospective analysis was performed. METHODS: From 01/1996 to 12/2012, clinico-pathological, surgical, and oncological features were retrospectively reviewed in a multicentric cohort of 154 surgically treated SCLC patients...

PURPOSE: Tracer injection into ovarian ligaments has been shown to detect sentinel nodes (SNs) in patients with ovarian cancer. To determine the possibility that SNs are missed, this feasibility study compared their detection during surgery with postoperative SPECT/CT. METHODS: In eight patients (either ovarian or endometrial cancer), after a staging lymphadenectomy including resection of SNs related to the ovary, SPECT/CT scans were performed within 24 hours. RESULTS: SPECT/CT identified hotspots in four patients at sites where SNs were resected...
