Introduction: Se measurement and supplementation in radiation oncology is a controversial issue. The German Working Group Trace Elements and Electrolytes in Oncology (AKTE) has conducted a number of studies on this issue, which are summarized in this review. Strategies have been tested and developed, aiming to stratify the patients with a potential need for supplemental Se and how best to monitor Se supplementation with respect to health effects and risks. Methods: We analyzed blood and tissue Se-levels of different tumor patients ( n = 512)...

Chemotherapy concurrent with radiotherapy has been widely used in clinical practice because the additional benefit on radiotherapy alone had shown. Head and neck cancer: CDDP concurrent with radiotherapy has been a standard treatment for 15years both in definitive setting and postoperative setting. Esophageal cancer: 5-FU/CDDP is the best partner for radiotherapy and appropriate radiation dose has been discussed. Anal cancer: Radical concurrent chemoradiotherapy with 5-FU and mitomycin C(MMC)remains the standard of care for squamous cell carcinoma of the anus...

BACKGROUND: The surgical management of malignant tumors in the head and neck region often leads to functional and esthetic defects that impair the quality of life of the patients. Reconstruction can be solved with prostheses in these cases, but various types of microsurgical free flaps can provide a better clinical outcome. CASE PRESENTATION: In this case report, the tumor and parts of the involved facial muscles and nerve were excised surgically from a 42-year-old patient after a third relapse of basal cell carcinoma in the left midface...

Background: Free-style flaps allow surgeons to overcome anatomical variations and raise perforator flaps wherever a pulsatile signal can be detected. We performed a systematic review and meta-analysis to identify the risk factors for complications and indications for free-style flaps in soft-tissue defect reconstructions. Methods: This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The databases of MEDLINE, PubMed, ScienceDirect, and Cochrane Library were searched from January 1991 to January 2017 for original articles describing free-style flaps in soft-tissue defect reconstruction...

The aim of this study was to survey the effects of the waiting time for the first oncology treatment in cancer diseases. By the analysis of 67 retrospective studies and reviews the numerical effects of treatment initiation time on survival were assessed. The "time factor" has a leading role on cancer types with aggressive biological behaviour, like breast cancer in younger age, testicular cancers, or head and neck tumours. However, a few days and reasonable delay to the first oncology intervention has no negative impact in numerous cancer diseases...

Older patients are at increased risk of toxicities from aggressive oncologic therapy and of nononcologic death. A meta-analysis of non-nasopharyngeal head and neck cancers showed no statistical benefit in adding chemotherapy to radiotherapy (RT) in older patients; another meta-analysis of RT versus chemoradiotherapy (CRT) in NPC found advantages to CRT, but vastly under-represented patients ≥70 years old. This is the largest study to date evaluating outcomes of CRT versus RT alone in this population. The National Cancer Data Base (NCDB) was queried for primary nasopharyngeal cancer cases (2004-2013) in patients ≥70 years old receiving RT alone or CRT...

OBJECTIVES: Post-acute care (PAC) centers, such as skilled nursing facilities, unskilled nursing facilities, lower acuity hospitals, and rehabilitation centers, serve to optimize recovery after acute care hospitalization. We aimed to identify factors associated with PAC utilization among patients undergoing head and neck cancer surgery with microvascular reconstruction because it may be helpful for patient decision making, discharge planning, and resource allocation. METHODS: Retrospective linked analysis of the 2011 to 2015 National Surgical Quality Improvement Program...

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide with high mortality and a lack of targeted therapies. To identify and prioritize druggable targets, we performed genome analysis together with genome-scale siRNA and oncology drug profiling using low passage tumor cells derived from a patient with a treatmentresistant HPV-negative HNSCC. EXPERIMENTAL DESIGN: A tumor cell culture was established and subjected to whole exome sequencing, RNA sequencing, comparative genome hybridization, and high-throughput phenotyping with siRNA library covering the druggable genome and an oncology drug library...

BACKGROUND AND PURPOSE: The Seikaly and Jha submandibular gland transfer surgery is performed to facilitate gland shielding during radiation therapy for head and neck tumors to circumvent radiation-induced xerostomia. It results in an asymmetric postsurgical appearance of the submandibular and submental spaces. Our purpose was to characterize the morphologic and enhancement characteristics of the transferred submandibular gland and identify potential pitfalls in postoperative radiologic interpretation...

PURPOSE: Overcoming the flaws of current data management conditions in head and neck oncology could enable integrated information systems specifically tailored to the needs of medical experts in a tumor board meeting. Clinical dashboards are a promising method to assist various aspects of the decision-making process in such cognitively demanding scenarios. However, in order to provide extensive and intuitive assistance to the participating physicians, the design and development of such a system have to be user-centric...

Eekers et al. have recently proposed a neuro-oncology atlas, which was co-authored by most centers associated in the European Proton Therapy Network (EPTN; Figure 1). With the introduction of new treatment techniques, such as integrated magnetic resonance imaging and linear accelerators (MR-linac) or particle therapy, the prediction of clinical efficacy of these more costly treatment modalities becomes more relevant. One of the side-effects of brain irradiation, being cognitive decline, is one of the toxicities most difficult to measure and predict...

HPV-driven oropharyngeal cancers have significantly better survival rates than tobacco and alcohol induced head and neck cancers. As HPV-positive patients are younger, healthier and far more likely to survive their disease, long-term treatment side effects are becoming a major issue. This has led the scientific and medical community to reassess the current treatment protocols in order to develop less toxic strategies while maintaining good oncological outcomes. In this article, we discuss the ongoing treatment de-escalation trials and highlight the issues raised by these studies...

Purpose: Uncertainties related to geometric distortion are a major obstacle for effectively utilizing MRI in radiation oncology. We aim to quantify the geometric distortion in patient images by comparing their in-treatment position MRIs with the corresponding planning CTs, using CT as the non-distorted gold standard. Methods: Twenty-one head and neck cancer patients were imaged with MRI as part of a prospective Institutional Review Board approved study. MR images were acquired with a T2 SE sequence (0...

Introduction: Outcome after postoperative radiochemotherapy (RT-CT) for patients with advanced head and neck squamous cell carcinomas (HNSCC) remains unsatisfactory, especially among those with HPV negative tumours. Therefore, new biomarkers are needed to further define subgroups for individualised therapeutic approaches. Preclinical and first clinical observations showed that the chemokine receptor CXCR4 and its ligand SDF-1 (CXCL12) play an important role in tumour cell proliferation, survival, cancer progression, metastasis and treatment resistance...

BACKGROUND: Patients who have undergone treatment for head and neck cancer are at risk for neck lymphedema, which can severely affect quality of life. Liposuction has been used successfully in cancer patients who suffer from post-treatment limb lymphedema. The purpose of our study was to review the outcomes of head and neck cancer patients at our center who have undergone submental liposuction for post-treatment lymphedema and compare their subsequent results with a control group. METHODS: All head and neck cancer patients at an oncology center in tertiary hospital setting who complained to their attending surgeon or radiation oncologist regarding cervical lymphedema secondary to head and neck cancer treatment, and had been disease-free for a minimum of one year, with no previous facial plastic surgical procedures were eligible for inclusion into the study...
