Wooil Kim, Chan Kyo Kim, Jung Jae Park, Minji Kim, Jae-Hun Kim
PURPOSE: To investigate the value of multiparametric magnetic resonance imaging (mpMRI) for extracapsular extension (ECE) in prostate cancer (PCa). MATERIALS AND METHODS: In all, 292 patients who received radical prostatectomy and underwent preoperative mpMRI at 3T were enrolled retrospectively. For determining the associations with ECE, the likelihood of ECE was assessed qualitatively on T2 -weighted imaging (T2 WI) and combined T2 WI and diffusion-weighted imaging (DWI) or dynamic contrast-enhanced imaging (DCEI)...

BACKGROUND: Postoperative radiotherapy has an important role in the treatment of prostate cancer, but personalised patient selection could improve outcomes and spare unnecessary toxicity. We aimed to develop and validate a gene expression signature to predict which patients would benefit most from postoperative radiotherapy. METHODS: Patients were eligible for this matched, retrospective study if they were included in one of five published US studies (cohort, case-cohort, and case-control studies) of patients with prostate adenocarcinoma who had radical prostatectomy (with or without postoperative radiotherapy) and had gene expression analysis of the tumour, with long-term follow-up and complete clinicopathological data...

BACKGROUND: Treatment intensification for resected, high-risk, head and neck squamous cell carcinoma (HNSCC) is an area of active investigation with novel adjuvant regimens under study. In this trial, the epidermal growth-factor receptor (EGFR) pathway was targeted using the IgG2 monoclonal antibody panitumumab in combination with cisplatin chemoradiotherapy (CRT) in high-risk, resected HNSCC. PATIENTS AND METHODS: Eligible patients included resected pathologic stage III or IVA squamous cell carcinoma of the oral cavity, larynx, hypopharynx, or human-papillomavirus (HPV)-negative oropharynx, without gross residual tumor, featuring high-risk factors (margins <1 mm, extracapsular extension, perineural or angiolymphatic invasion, or ≥2 positive lymph nodes)...

INTRODUCTION: Adjuvant radiotherapy is proven to prevent lymph node field relapse after therapeutic lymphadenectomy for melanoma, but does not improve overall survival based on current data. There remains a high rate of distant relapse. This study reports patterns of failure in patients treated with adjuvant radiotherapy, looking at factors associated with distant metastasis and comparing this to recent literature. METHODS: This retrospective study included patients treated with adjuvant nodal irradiation after lymphadenectomy between June 2012 and March 2015...

Skin sparing mastectomy, a surgical procedure sparing a large portion of the overlying skin of the breast, and nipple-sparing mastectomy, sparing the whole nipple-areolar complex, are increasingly used, although their oncologic efficacy remains unclear. The aim of this study was to assess the radiation oncologists' opinions regarding the indications of radiation therapy (RT) after skin-sparing mastectomy and nipple-sparing mastectomy. Radiation oncology members of four national and international societies were invited to complete a questionnaire comprising of 22 questions to assess their opinions regarding RT indications in the context of skin-sparing and nipple-sparing mastectomy...

Patients with resected oral squamous cell carcinoma (OSCC) harboring extracapsular extension (ECE) of the involved lymph node, show poor and heterogeneous outcomes. We aim to improve their prognostic stratification by combining genetic information from next-generation sequencing (NGS) using traditional clinicopathological prognosticators. The hotspot mutation regions of 45 cancer-related genes were investigated using NGS with an ultra-deep (>1000×) sequencing approach in formalin-fixed paraffin-embedded samples obtained from 201 patients with resected OSCC harboring ECE...
