Benefits and drawbacks of videoconferencing for collaborating multidisciplinary teams in regional oncology networks:a scoping review

INTRODUCTION: Various forms of videoconferenced collaborations exist in oncology care. In regional oncology networks, multidisciplinary teams (MDTs) are essential in coordinating care in their region. There is no recent overview of the benefits and drawbacks of videoconferenced collaborations in oncology care networks. This scoping review presents an overview of videoconferencing (VC) in oncology care and summarises its benefits and drawbacks regarding decision-making and care coordination. DESIGN: We searched MEDLINE, Embase, CINAHL (nursing and allied health) and the Cochrane Library from inception to October 2020 for studies that included VC use in discussing treatment plans and coordinating care in oncology networks between teams at different sites. Two reviewers performed data extraction and thematic analyses. RESULTS: Fifty studies were included. Six types of collaboration between teams using VC in oncology care were distinguished, ranging from MDTs collaborating with similar teams or with national or international experts to interactions between palliative care nurses and experts in that field. Patient benefits were less travel for diagnosis, better coordination of care, better access to scarce facilities and treatment in their own community. Benefits for healthcare professionals were optimised treatment plans through multidisciplinary discussion of complex cases, an ability to inform all healthcare professionals simultaneously, enhanced care coordination, less travel and continued medical education. VC added to the regular workload in preparing for discussions and increased administrative preparation. DISCUSSION: Benefits and drawbacks for collaborating teams were tied to general VC use. VC enabled better use of staff time and reduced the time spent travelling. VC equipment costs and lack of reimbursement were implementation barriers. CONCLUSION: VC is highly useful for various types of collaboration in oncology networks and improves decision-making over treatment plans and care coordination, with substantial benefits for patients and specialists. Drawbacks are additional time related to administrative preparation

Identification and validation of WISP1 as an epigenetic regulator of metastasis in oral squamous cell carcinoma

Lymph node (LN) metastasis is the most important prognostic factor in oral squamous cell carcinoma (OSCC) patients. However, in approximately one third of OSCC patients nodal metastases remain undetected, and thus are not adequately treated. Therefore, clinical assessment of LN metastasis needs to be improved. The purpose of this study was to identify DNA methylation biomarkers to predict LN metastases in OSCC. Genome wide methylation assessment was performed on six OSCC with (N+) and six without LN metastases (N0). Differentially methylated sequences were selected based on the likelihood of differential methylation and validated using an independent OSCC cohort as well as OSCC from The Cancer Genome Atlas (TCGA). Expression of WISP1 using immunohistochemistry was analyzed on a large OSCC cohort (n = 5204). MethylCap-Seq analysis revealed 268 differentially methylated markers. WISP1 was the highest ranking annotated gene that showed hypomethylation in the N+ group. Bisulfite pyrosequencing confirmed significant hypomethylation within the WISP1 promoter region in N+ OSCC (P = 0.03) and showed an association between WISP1 hypomethylation and high WISP1 expression (P = 0.01). Both these results were confirmed using 148 OSCC retrieved from the TCGA database. In a large OSCC cohort, high WISP1 expression was associated with LN metastasis (P = 0.05), disease-specific survival (P = 0.022), and regional disease-free survival (P = 0.027). These data suggest that WISP1 expression is regulated by methylation and WISP1 hypomethylation contributes to LN metastasis in OSCC. WISP1 is a potential biomarker to predict the presence of LN metastases. (c) 2015 Wiley Periodicals, Inc
