Purpose: Human papillomavirus (HPV)-associated oropharyngeal squamous cell cancer (OPSCC) has a much better prognosis than HPV-negative OPSCC, and this is linked to dense tumor immune infiltration. As the viral antigens may trigger potent immunity, we studied the relationship between the presence of intratumoral HPV-specific T-cell responses, the immune contexture in the tumor microenvironment, and clinical outcome.Experimental Design: To this purpose, an in-depth analysis of tumor-infiltrating immune cells in a prospective cohort of 97 patients with HPV16-positive and HPV16-negative OPSCC was performed using functional T-cell assays, mass cytometry (CyTOF), flow cytometry, and fluorescent immunostaining of tumor tissues. Key findings were validated in a cohort of 75 patients with HPV16-positive OPSCC present in the publicly available The Cancer Genome Atlas database.Results: In 64% of the HPV16-positive tumors, type I HPV16-specific T cells were present. Their presence was not only strongly related to a better overall survival, a smaller tumor size, and less lymph node metastases but also to a type I-oriented tumor microenvironment, including high numbers of activated CD161 þ T cells, CD103 þ tissue-resident T cells, dendritic cells (DC), and DC-like macrophages. Conclusions:The viral antigens trigger a tumor-specific T-cell response that shapes a favorable immune contexture for the response to standard therapy. Hence, reinforcement of HPV16-specific T-cell reactivity is expected to boost this process. Clin Cancer Res; 24(3); 634-47. Ó2017 AACR.
PurposeThe purpose of this study was to investigate the feasibility of an online self-management application (OncoKompas) among cancer survivors. In OncoKompas, cancer survivors can monitor their quality of life (QOL) via participant reported outcomes (PROs) (“Measure”), which is followed by automatically generated individually tailored feedback (“Learn”) and personalized advice on supportive care services (“Act”).MethodsA pretest–posttest design was used, conducting a survey before providing access to OncoKompas, and 2 weeks after, followed by an interview by a nurse. Adoption was defined as the percentage of cancer survivors that agreed to participate in the study and returned the T0 questionnaire. Implementation was defined as the percentage of participants that actually used OncoKompas as intended (T1). General satisfaction was assessed based on the mean score of three study-specific questions: (1) general impression of OncoKompas, (2) the user-friendliness, and (3) the ability to use OncoKompas without assistance (10-point Likert scales). Furthermore, satisfaction was measured with the Net Promotor Scale (NPS).ResultsOncoKompas was feasible with an adoption grade of 64 %, an implementation grade of 75–91 %, a mean satisfaction score of 7.3, and a positive NPS (1.9). Sociodemographic and clinical factors and QOL were not associated with satisfaction. Several facilitators and barriers related to the feasibility of OncoKompas were identified.ConclusionOncoKompas is considered feasible, but has to be further improved. In order to enhance feasibility and increase satisfaction, we have to balance the time it takes to use OncoKompas, measurement precision, and tailoring towards personalized advices.
The results of the initial study concerning ease of use for the medical professionals and decreased discomfort for the patients of the new anterograde replacement procedure of the Provox 2 prosthesis were confirmed. The device life of Provox and that of Provox 2 were comparable, despite the alterations needed to optimize the Provox 2 prosthesis for the anterograde procedure.
The immunohistochemical expression patterns of cytokeratins 8 and 18 and vimentin were examined in frozen sections of 120 human mucosal squamous cell carcinomas with special emphasis on the topological distribution in the tumour. This was done in order to evaluate in squamous cell carcinoma a particular expression pattern observed recently by us in transitional cell carcinoma of the urinary tract and designated as an 'interface phenomenon'. This phenomenon implying maximum expression of cytokeratins 8 and 18 at the tumour front, and to a lesser extent also in areas of intratumorous stroma contact, was also found in about 50 per cent of the squamous cell carcinomas examined. It was even found for vimentin, which contrasted with transitional cell carcinoma. The percentages of occurrence of the phenomenon varied for the different sites of origin of the tumour. Tumour grade did not influence the results. These findings further support the idea that invasive carcinoma cells interacting with the stromal micro-environment display a characteristic intermediate filament phenotype that deviates from the pattern expected on the basis of their direction of differentiation. These changes might reflect phenotype involved in invasive, migrating, and proliferating activities.
An update of the literature on physical and psychosocial aspects of head and neck cancer, with special emphasis on effects of treatment, patient-related factors and psychosocial intervention on quality of life (QoL). QoL deteriorates during and directly after treatment and returns only slowly to pre-treatment values. Organ preservation, gender and coping-strategies are factors related to QoL after treatment. As prognosis and survival were found to be comparable under different treatment regimes, we noticed a gradual shift in therapy towards organ preservation. Systematic care, using specific instruments is important for improving the QoL. We feel that more attention should be given to improving support, in order to optimize the QoL of patients during the palliative stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
