BACKGROUND: The optimal extent of lymph node (LN) dissection remains controversial in adenocarcinoma of the esophagogastric junction (AEG), especially in Siewert types II and III. The aim of this study was to analyze clinicopathological characteristics of patients with Siewert type II and III AEGs to clarify whether pyloric (no. 5 and no.6) lymphadenectomy is essential in these patients. METHODS: A retrospective analysis was performed in the Third Affiliated Hospital of Soochow University from September 2008 to December 2012, and clinicopathological characteristics on all patients with Siewert type II and III AEGs, who underwent curative total gastrectomy with lymphadenectomy were collected...

OBJECTIVES: To evaluate the survival benefits that lymph node dissection (LND) brought to clinically node-negative upper tract urothelial carcinoma (UTUC) patients. METHODS: Non-metastatic node-negative UTUC patients were identified from the Surveillance, Epidemiology and End Results database. N0 patients were naturally divided as cN0-pNx group (clinically diagnosed as N0 without LND performed) and cNx-pN0 group (pathologically diagnosed as node-negative no matter what clinical node status they have)...

Laparoscopic D3 lymph node dissection for transverse colon cancer is technically demanding because of complicated anatomy. Here, we reviewed the vascular structure of the transverse mesocolon, explored the extent of the base of the transverse mesocolon, and evaluated the feasibility and oncological safety of D3 lymph node dissection. We retrospectively reviewed the clinical records of 42 patients with advanced transverse colon cancer who underwent curative surgery and D3 dissection at Kyushu University Hospital between January 2008 and December 2015...

Disseminated carcinomatosis of the bone marrow (DCBM) is characterized by diffuse metastasis to bone marrow and sudden mortality. To the best of our knowledge, no studies to date have reported progression of oral squamous cell carcinoma to DCBM. Herein, we report a case of squamous cell carcinoma in the maxillary gingiva suspected of progressing to DCBM. A 64-year-old woman presented with white lesions on the left maxillary gingiva. The lesions were diagnosed as squamous cell carcinoma (T2, N0, M0), and partial maxillectomy performed...

INTRODUCTION: Robotic-assisted laparoscopic prostatectomy (RALP) has largely replaced open radical prostatectomy in many centers. Radical perineal prostatectomy (RPP) is another less invasive approach that has not been widely adopted. RPP offers excellent exposure of the urinary sphincter and bladder neck that may provide good urinary function outcomes. We evaluate urinary function after RALP and RPP. METHODS: Retrospective review of a prospective radical prostatectomy database was performed...

A 76-year-old Caucasian woman presented with a 3-year history of a recurrent pruritic eruption on the hips, thighs, and under the breasts associated with intermittent lesions resembling vesicles and bullae that failed to respond to topical corticosteroids. She had a history of severe lichen sclerosis et atrophicus, leading to invasive squamous cell carcinoma of the vulva for which she underwent radical vulvectomy and bilateral inguino-femoral lymph node dissection. On physical examination, involving the inframammary breasts, abdomen, hips, and proximal thighs there were multiple erosions with hemorrhagic crust and multiple clustered translucent papules...

BACKGROUND: In head and neck cancer, the presence of extranodal extension (ENE) in lymph nodes (LNs) has been shown prospectively to require adding chemotherapy to postoperative radiation therapy (RT). Limited data exist regarding ENE in LNs from primary penile cancer (PeCa). OBJECTIVE: To determine the association of RT and ENE in PeCa. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analyzed the outcomes of 93 patients with pT1-4 N3 M0 (American Joint Committee on Cancer 7th edition) squamous cell carcinoma of the penis across four international centers...

Two recent randomised studies found no survival difference in patients, who had melanoma with metastasis to the sentinel node (SN) and underwent immediate complete lymph node dissection (CLND), compared with patients, who were followed closely with ultrasound scans and only underwent CLND if metastases developed. From 2018, the Danish guidelines concur: SN-positive patients will no longer undergo routine CLND, which has high morbidity, but will be followed with ultrasound scans of the SN-positive region(s) at their follow-up visits every third month for two years, then every six month for three years, except if PET-CT is performed...

Purpose To evaluate a radiomics model for predicting lymph node (LN) metastasis in biliary tract cancers (BTCs) and to determine its prognostic value for disease-specific and recurrence-free survival. Materials and Methods For this retrospective study, a radiomics model was developed on the basis of a primary cohort of 177 patients with BTC who underwent resection and LN dissection between June 2010 and December 2016. Radiomic features were extracted from portal venous CT scans. A radiomics signature was built on the basis of reproducible features by using the least absolute shrinkage and selection operator method...

Rosai-Dorfman disease is a rare histiocytic disorder shown to have gene mutations that activate the MAPK/ERK pathway in at least one-third of cases. Most patients with Rosai-Dorfman disease present with bulky lymphadenopathy or extranodal disease, but rarely Rosai-Dorfman disease is detected concomitantly with lymphoma in the same biopsy specimen. The underlying molecular mechanisms of focal Rosai-Dorfman disease occurring in the setting of lymphoma have not been investigated. We report 12 cases of Rosai-Dorfman disease and lymphoma involving the same anatomic site...

Purpose: Axillary lymph node dissection (ALND) may be avoidable for breast cancer patients with 1-2 positive lymph nodes (LN) after breast-conserving therapy. However, the effects of ALND after mastectomy remain unclear because radiation is not routinely used. Herein, we compared the benefits of post-mastectomy ALND versus sentinel node biopsy (SNB) alone for breast cancer patients with 1-3 metastatic LNs. Materials and Methods: A total of 1,697 patients with pN1 disease who underwent mastectomy during 2000-2015 were identified from an institutional database...

INTRODUCTION: Vancomycin is one of the most widely used antibiotics for the treatment of serious infectious caused by methicillin-resistant Staphylococcus aureus (MRSA). However, reduced susceptibility of S. aureus to vancomycin has been observed in recent years. We report on a case of vancomycin resistant methicillin-resistant Staphylococcus aureus (VRSA) enteritis after colon reconstruction followed by esophagectomy and completion gastrectomy, with extended lymph node dissection for esophageal squamous cell carcinoma...

REVIEW
David Cibula, W Glenn McCluggage
Sentinel lymph node (SLN) biopsy has been increasingly used in the management of early-stages cervical cancer instead of systematic pelvic lymph node dissection (PLND). The aim of this article is to give a critical overview of key aspects related to this concept, such as a necessity for reliable detection of micrometastases (MIC) in SLN and the requirements for SLN pathologic ultrastaging, low accuracy of intraoperative detection of SLN involvement, and still a limited evidence of oncological safety of the replacement of PLND by SLN biopsy only in ≥IB1 tumours due to unknown risk of MIC in non-SLN pelvic lymph nodes in patients with negative SLN, and absence of any prospective evidence...

The incidence of sparganosis, a parasitic disease caused by plerocercoid larvae of the genus Spirometra, has gradually risen worldwide (especially in remote areas) in recent years. Pulmonary and pleural sparganosis, as well as other sites of infestation, including the subcutaneous tissues, the abdominal viscera, brain and eyes, has been reported. In clinical practice, due to the atypical signs and symptoms and limited laboratory approaches for the specific detection of sparganum, sparganosis is often misdiagnosed...
