Tongue pressure is reportedly associated with dysphagia. This study investigated relationships among characteristics of head and neck cancer, tongue pressure and dysphagia screening tests performed in patients with head and neck cancer during the acute phase after surgical resection. Fifty-seven patients (36 men, 21 women; age range 26-95 years) underwent surgical resection and dysphagia screening tests (Repetitive Saliva Swallowing Test, Water Swallowing Test, Modified Water Swallowing Test and Food Test) and pre- and postoperative measurement of tongue pressure at 5 time points (preoperatively, and 1-2 weeks and 1, 2, and 3 months postoperatively)...

The primary aim was to determine the efficacy of the Distress Thermometer (DT) in screening for anxiety and mood problems against the University of Washington Quality of Life, version 4 (UWQOL). Secondary aims were to evaluate the association between demographic, clinical and health-related QOL variables with significant distress. Two hundred and sixty one disease-free HNC ambulatory patients attending routine follow-up clinics were prospectively recruited. Both DT and UWQOL were completed pre-consultation...

AIM: The authors report the results of a multicenter retrospective series with a long-term follow-up and the analysis of clinical, radiological, surgical data as well as the complementary treatments in patients with intramedullary astrocytomas (IA). MATERIALS AND METHODS: We performed a retrospective analysis of all the patients with IA operated on between 1984 and 2011 at 7 French centers (Kremlin-Bicêtre, Lille, Lyon, Marseille, Montpellier, Nice, and Nîmes)...

PURPOSE: To evaluate the feasibility and impact of using a novel advanced PET auto-segmentation method in Head and Neck (H&N) radiotherapy treatment (RT) planning. METHODS: ATLAAS, Automatic decision Tree-based Learning Algorithm for Advanced Segmentation, previously developed and validated on pre-clinical data, was applied to (18)F-FDG-PET/CT scans of 20 H&N patients undergoing Intensity Modulated Radiation Therapy. Primary Gross Tumour Volumes (GTVs) manually delineated on CT/MRI scans (GTVpCT/MRI), together with ATLAAS-generated contours (GTVpATLAAS) were used to derive the RT planning GTV (GTVpfinal)...

OBJECTIVE: Bowel dysfunction is common following a restorative rectal cancer resection, but symptom severity and the degree of quality of life impairment is highly variable. An internationally validated patient-reported outcome measure, Low Anterior Resection Syndrome (LARS) score, now enables these symptoms to be measured. The study purpose was: (1) to develop a model that predicts postoperative bowel function; (2) externally validate the model and (3) incorporate these findings into a nomogram and online tool in order to individualise patient counselling and aid preoperative consent...

: Radical prostatectomy (RP) for prostate cancer treatment, although effective, can lead to severe erectile dysfunction. This study describes a new technique, which aims to reestablish the nerve stimulus in penile erection by two sural nerve graft bridges bilaterally, using the end to side neurorraphy. The first bridge is between femoral nerve and dorsal nerve of penis and the second, is between the femoral nerve and the interior of the corpus cavernosum. In this neurorraphy the endings of the newly formed fibres, generated by the femoral nerve, release acetylcholine inside the cavernous bodies, beginning the erection mechanism...

BACKGROUND: Role of chemotherapy in patients who continue to have unresectable disease after pre-operative chemo-radiotherapy (CRT) remains largely unaddressed. METHODS: Patients with LA rectal cancer from January 2013 to June 2015 were evaluated. Post-CRT, patients, who were deemed unresectable, were considered for further interim chemotherapy (i-CT). RESULTS: Seventy six patients (15%) with median age of 38.5 years received i-CT after CRT...

BACKGROUND: The number of lymph node retrieved in the surgical specimen is important for tumor staging and has paramount impact on prognosis in colorectal cancer and imitates the adequacy of lymph node surgical clearance. The paucity of lymph node yields in patients undergoing resection after preoperative chemo radiotherapy (CRT) in rectal cancer has seen. Lower total number of lymph nodes in the total mesoractal excision (TME) specimen after CRT, could a marker of better tumor response...

Wilms tumour is named after Max Wilms. It is an embryonal tumour derived from the metanephros. It is the commonest childhood renal tumour and the third commonest paediatric malignancy. Synchronous bilateral Wilms tumours (BWT) represent 4-7% of all Wilms tumours (WT) and present at a younger age than unilateral Wilms tumours. At least 10% of synchronous BWTs have unfavourable histology, and up to 22% are associated with genitourinary abnormalities, aniridia, WAGR syndrome, Denys-Drash Syndrome, hemihypertrophy, or one of the other overgrowth syndromes...

BACKGROUND: Axillary surgery is an established part of the management of primary breast cancer. It provides staging information to guide adjuvant therapy and potentially local control of axillary disease. Several alternative approaches to axillary surgery are available, most of which aim to spare a proportion of women the morbidity of complete axillary dissection. OBJECTIVES: To assess the benefits and harms of alternative approaches to axillary surgery (including omitting such surgery altogether) in terms of overall survival; local, regional and distant recurrences; and adverse events...

PURPOSE: To determine whether the Microsoft Kinect Version 2 (Kinect v2), a commercial off-the-shelf (COTS) depth sensors designed for entertainment purposes, were robust to the radiotherapy treatment environment and could be suitable for monitoring of voluntary breath-hold compliance. This could complement current visual monitoring techniques, and be useful for heart sparing left breast radiotherapy. METHODS: In-house software to control Kinect v2 sensors, and capture output information, was developed using the free Microsoft software development kit, and the Cinder creative coding C++ library...

PURPOSE: NSCLC radiotherapy treatment is a trade-off between controlling the tumor while limiting radiation-induced toxicities. Here we identify hierarchical biophysical relationships that could simultaneously influence both local control (LC) and RP by using an integrated Bayesian Networks (BN) approach. METHODS: We studied 79 NSCLC patients treated on prospective protocol with 56 cases of LC and 21 events of RP. Beyond dosimetric information, each patient had 193 features including 12 clinical factors, 60 circulating blood cytokines before and during radiotherapy, 62 microRNAs, and 59 single-nucleotide polymorphisms (SNPs)...

PURPOSE: To investigate the incorporation of pre-therapy regional ventilation function in predicting radiation fibrosis (RF) in stage III non-small-cell lung cancer (NSCLC) patients treated with concurrent thoracic chemoradiotherapy. METHODS: 37 stage III NSCLC patients were retrospectively studied.

BACKGROUND: Sinonasal undifferentiated carcinoma is a rare aggressive tumour arising from the Schneiderian epithelium lining the sinonasal tract. Although considered the cornerstone of therapy, surgical resection can only be performed in a limited number of patients. This report describes the experience of treating sinonasal undifferentiated carcinoma with a multimodality approach. METHOD: The treatment charts of sinonasal undifferentiated carcinoma patients treated at a tertiary care centre from 2004 to 2012 were retrospectively reviewed...

Soft tissue sarcomas (STS) are rare tumours arising in mesenchymal tissues, and can occur almost anywhere in the body. Their rarity, and the heterogeneity of subtype and location means that developing evidence-based guidelines is complicated by the limitations of the data available. However, this makes it more important that STS are managed by teams, expert in such cases, to ensure consistent and optimal treatment, as well as recruitment to clinical trials, and the ongoing accumulation of further data and knowledge...
