Department of Otorhinolaryngology, Region Hospital West Jutland, Holstebro, Denmark; Department of Clinical Medicine, Aarhus University, Aarhus C, Denmark.

Background: We aimed to compare the predictive performance of pN-categories in oral squamous cell carcinoma (OSCC) encompassing the most recent 8th edition (TNM8), its predecessor (TNM7), and a newly proposed algorithm (pN-N), which classifies patients according to the number of positive lymph nodes and extranodal extension.

Methods: Consecutive, primary OSCC patients from seven previously published cohorts were included and classified according to the three pN-classifications: TNM7, TNM8 and pN-N. Overall survival probabilities were summarised with the Kaplan-Meier method. Read More

D2 dissection improves disease-specific survival in advanced gastric cancer patients: 15-year follow-up results of the Italian Gastric Cancer Study Group D1 versus D2 randomised controlled trial.

Eur J Cancer 2021 Apr 19;150:10-22. Epub 2021 Apr 19.

Department of Surgery, Yodogawa Christian Hospital, Yodogawa, Japan.

Background: The extended lymphadenectomy (D2) was recently introduced in several guidelines as the optimal treatment for gastric cancer, based only on the 15-year follow-up results of the Dutch randomised trial, while the British Medical Research Council (MRC) study failed to demonstrate a survival benefit over the more limited D1 dissection. The Italian Gastric Cancer Study Group randomised controlled trial (RCT) was also undertaken to compare D1 versus D2 gastrectomy, and a tendency to improve survival in patients with advanced resectable disease (pT > 1N+) was documented despite negative results in the entire patient population. Now we present the 15-year follow-up results of survival and gastric cancer-related mortality. Read More

Vet Comp Oncol 2021 Apr 22. Epub 2021 Apr 22.

Dipartimento di Medicina Veterinaria, Università degli Studi di Milano, Milan, Italy.

Tumor stage is a prognostic indicator for canine malignant head and neck tumors (MHNT). However, consensus is lacking on nodal staging in the absence of clinically apparent nodal disease (cN0 neck). This prospective observational study aims to determine the diagnostic accuracy of radiopharmaceutical and blue dye for sentinel lymph node biopsy (SLNB), to assess the correspondence between sentinel lymph node (SLN) and clinically expected regional lymph node (RLN) and the impact on staging of the procedure in dogs with MHNT and cN0 neck.

Flap fixation in preventing seroma formation after mastectomy: an updated meta-analysis.

Updates Surg 2021 Apr 22. Epub 2021 Apr 22.

Department of Advanced Biomedical Sciences, University of Naples "Federico II", Via Pansini n.5, 80131, Naples, Italy.

Seroma formation following mastectomy is one of the most experienced complications, with a very variable incidence ranging from 3 to 90%. In recent years, many publications have been realized to define an effective technique to prevent its formation and several approaches have been proposed. Given the potential of flap fixation in reducing seroma formation, we performed a meta-analysis of the literature to investigate the role of this approach as definitive gold standard in mastectomy surgery.

Soluble Neuropilin-1 is an independent marker of poor prognosis in early breast cancer.

J Cancer Res Clin Oncol 2021 Apr 21. Epub 2021 Apr 21.

Department of Gynecology and Obstetrics, University Hospital Essen, University of Duisburg-Essen, Essen, Germany.

Background: Neuropilin-1 (NRP-1) is a transmembrane protein that acts as a multifunctional non-tyrosine kinase receptor with an established role in development and immunity. NRP-1 also regulates tumor biology, and high expression levels of tissue NRP-1 have been associated with a poor prognosis. Recently, ELISA-based quantification of soluble NRP-1 (sNRP-1) has become available, but little is known about the prognostic value of sNRP-1 in malignancies. Read More

A proposal for uniformity in classification of lymph node stations in esophageal cancer.

Dis Esophagus 2021 Mar 17. Epub 2021 Mar 17.

Department of Surgery, Amsterdam UMC, University of Amsterdam, Cancer Center Amsterdam, Amsterdam, The Netherlands.

The 11th edition of the "Japanese Classification of Esophageal Cancer" by the Japan Esophageal Society (JES) and the 8th edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) "Cancer Staging Manual" are two separate classification systems both widely used for the clinical and pathological staging of esophageal cancer. Furthermore, the lymph node stations from these classification systems are combined for research purposes in the multinational TIGER study, which investigates the distribution pattern of lymph node metastases. The existing classification systems greatly differ with regard to number, location and anatomical boundaries of locoregional lymph node stations. Read More

Enhancing subcutaneous injection and target tissue accumulation of nanoparticles co-administration with macropinocytosis inhibitory nanoparticles (MiNP).

Nanoscale Horiz 2021 Apr 22. Epub 2021 Apr 22.

Department of Biomedical Engineering, Northwestern University, 2145 Sheridan Road, Evanston, IL 60208, USA.

A significant barrier to the application of nanoparticles for precision medicine is the mononuclear phagocyte system (MPS), a diverse population of phagocytic cells primarily located within the liver, spleen and lymph nodes. The majority of nanoparticles are indiscriminately cleared by the MPS via macropinocytosis before reaching their intended targets, resulting in side effects and decreased efficacy. Here, we demonstrate that the biodistribution and desired tissue accumulation of targeted nanoparticles can be significantly enhanced by co-injection with polymeric micelles containing the actin depolymerizing agent latrunculin A.
