Pathological complete response is achievable with mFOLFOX6 plus cetuximab therapy for unresectable colorectal cancer with multiple paraaortic lymph node metastases (mCRC) despite right-sided colonic origin. A 62-year-old woman with synchronous paraaortic lymph node metastases of transverse colon cancer was treated with mFOLFOX6 plus cetuximab as first-line therapy. The tumor size was markedly decreased following 6 courses of chemotherapy, and all lymph node metastases had disappeared. The patient then underwent conventional right hemicolectomy with D3 lymph node dissection plus sampling excision of the paraaortic lymph nodes...

It is often difficult to correctly diagnose patients who present with dilation of the bile duct. Cholangiocarcinoma, primary sclerosing cholangitis (PSC) and immunoglobulin (Ig)G4-related sclerosing cholangitis must be considered as potential diagnoses for these cases. The current study presents a 73-year-old female patient who presented with a high fever and abdominal pain. Contrast-enhanced computed tomography and magnetic resonance cholangiopancreatography revealed stenosis and dilation of the intrahepatic bile duct without solid components...

BACKGROUND: In patients with prostate cancer (PCa) with histopathologically proven pelvic lymph node (LN) metastasis (pN1) after extended pelvic lymph node dissection (ePLND), multimodality treatment consisting of treatment of the primary tumor and whole pelvic radiotherapy (WPRT) combined with androgen deprivation therapy (ADT) offers promising results, leading to better cause-specific survival rates compared with ADT alone. However, in case more than one pelvic LN is invaded by the tumor, approximately 40% of the patients relapse biochemically and clinically...

Little is known concerning the prognostic significance of the degree of lymphatic vessel invasion in pancreatic head cancer. To address this gap in knowledge, we retrospectively examined 60 patients with locally advanced, surgically resectable pancreatic head cancer who underwent pancreaticoduodenectomy and lymph node (LN) dissection.All cases were histopathologically diagnosed as ductal adenocarcinoma, stage II (25 pT3N0 cases, 35 pT3N1 cases). The following variables were investigated: age; sex; neoadjuvant therapy; adjuvant therapy; tumor size; tumor grade; invasion into the serosa, retropancreatic tissue, duodenum, bile duct, portal venous system and perineural area; cut margins; LN metastasis; and the number of invaded lymphatic vessels (LVI-score)...

The progression of colon cancer (CC) involves hematogenous and lymphatic spread to locoregional lymph nodes (LN), distant LN, and metastatic sites including the liver. The biological mechanisms that govern CC progression remain elusive. The Halsted model assumes an orderly, stepwise progression from the primary tumor to nearby nodes, henceforth to anatomically more distant nodes, and ultimately to distant organs. The Fisher model, on the other hand, regards the release of metastatic cells as early and essentially random events...

BACKGROUND: Endoscopic transoral thyroidectomy is a recently introduced technique of remote access thyroidectomy. We previously reported the feasibility of the robotic approach (TORT). Nevertheless, experience to date is limited, with scant data on outcomes in patients with papillary thyroid carcinoma (PTC). METHODS: This was a retrospective analysis of prospectively collected data. Patients with PTC, who underwent TORT at a single center between March 2016 and February 2017, were analyzed...

BACKGROUND: Papillary thyroid microcarcinomas (PTMCs) often demonstrate lateral lymph node (LN) metastasis. The purpose of this study was to assess whether the size of primary tumor should be considered in deciding lateral neck dissection extent. METHODS: We conducted a retrospective comparison of patients with PTMC and papillary thyroid carcinoma (PTC) larger than 1 cm who received lateral LN dissection from 2009 to 2015. RESULTS: PTMC group had more frequent metachronous metastasis, multifocality, less involvement of lower third thyroid, lower metastatic central LN counts and ratio, and lower metastatic total LN ratio...

BACKGROUND: Fine-needle aspiration (FNA) cytology has been the standard of care in the workup of cervical lymph nodes (LNs) in patients with recurrent papillary thyroid cancer (PTC) and suspicious cervical LNs. Recently, FNA thyroglobulin (TG) washout measurement has been proposed as an adjunct in the management of these patients. We hypothesize that using FNA-TG washout for suspicious cervical LNs would increase the accuracy of diagnosing metastatic disease especially in cystic and highly vascular cervical LN in patients with recurrent PTC...

A 65-year-old woman who had been diagnosed with dermatomyositis presented to the hospital with a small bowel mass. She had tested positive for fecal occult blood test and anemia at a medical checkup;therefore, computerized tomography (CT) was performed at the previous hospital and it had revealed thickening of the intestinal wall. Abdominal contrast-enhanced CT, single-balloon assisted enteroscopy, and biopsy led to a diagnosis of poorly differentiated jejunal adenocarcinoma. The patient underwent laparoscopic segmental resection of the jejunum with dissection of mesenteric lymph nodes...

BACKGROUND: Radical cystectomy (RC) may occasionally be performed in individuals with metastatic urothelial carcinoma of the bladder (mUCB). However, the role of lymph node dissection (LND) for such cases is unknown. Thus, we tested the effect of RC on cancer-specific mortality (CSM) and overall mortality in mUCB patients and the effect of LND and its extent on CSM. PATIENTS AND METHODS: Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2013), we identified patients with mUCB who underwent RC with or without LND or non-RC management...

Advances in endoscopic-assisted neck surgery have allowed surgeons to conceal the scars via various approaches. However, studies comparing the approaches are still rare. The aim of this study was to comparatively analyze the feasibility and oncological outcomes of the retroauricular approach (RA) and the small transcervical approach (STC) for endoscopic-assisted selective neck dissection (EASND). Five fresh cadavers were recruited. EASND was performed via RA on one side and via STC on the contralateral side of each of the cadavers...

BACKGROUND: Variation in the management of PNETs exist due to the limited high-level evidence to guide clinical practice. The aim of this work is to generate consensus guidelines with a Delphi process for managing PNETs. METHODS: A panel of experts reviewed the surgical literature and scored a set of clinical case statements using a web-based survey to identify areas of agreement and disagreement. Results of the survey were discussed after each round of review. This cycle was repeated until no further likelihood of reaching consensus existed...

OBJECTIVE: Nodal volume as a prognostic factor has been extensively evaluated in head and neck cancer, however there is still no consensus. We attempted to analyze nodal volume as a prognostic factor in head and neck cancer treated with chemoradiation (CCRT) without an elective neck dissection with image guided intensity modulated radiotherapy (IG-IMRT). MATERIAL AND METHODS: We prospectively analysed 87 patients of Stage III-IV cancer of the oropharynx (57), and hypopharynx (30), who subsequently received definitive concurrent chemoradiation...

OBJECTIVE: To investigate the rate of occult SN metastases, oncological outcome, and association of recurrence with the pattern of lymphatic tumour drainage in RCC. MATERIALS AND METHODS: A pooled RCC sub-group analysis was conducted of secondary endpoints from a published feasibility and a phase II prospective single-arm SN study to investigate oncological outcome. Patients with cT1-3 (<10 cm) cN0M0 RCC of any sub-type were enrolled. After intratumoural injection of Tc99m nanocolloid, pre-operative imaging of SNs with SPECT/CT was followed by (partial) nephrectomy with SN and regional lymph node dissection using a γ-probe...
