ReviewTowards an evidence-informed value scale for surgical and radiation oncology: a multi-stakeholder perspective.
Surgery and radiotherapy, two locoregional cancer treatments, are essential to help improve cancer outcomes, control, and palliation. The continued evolution in treatment processes, techniques, and technologies-often at substantially increased costs-demands for direction on outcomes that are most valued by patients, and the evidence that is required before clinical adoption of these practices. Three recently introduced frameworks-the European Society for Medical Oncology Magnitude of Clinical Benefit Scale, the American Society of Clinical Oncology Value Framework, and the National Comprehensive Cancer Network Blocks-which all help define the value of oncology treatments, were appraised with a focus on their methods and definition of patient benefit. ⋯ Findings show that these frameworks are not immediately transferable to locoregional cancer treatments. Moreover, the lack of emphasis on patient perspective and the reliance on traditional, trial-based endpoints such as survival, disease-free survival, and safety, calls for a new framework that includes real-world evidence with focus on the whole spectrum of patient-centred endpoints. Such an evidence-informed value scale would safeguard against the proliferation of low-value innovation while simultaneously increasing access to treatments that show significant improvements in the outcomes of cancer care.

ReviewEssential TNM: a registry tool to reduce gaps in cancer staging information.
Accurate information on the extent of disease around the time of diagnosis is an important component of cancer care, in defining disease prognosis, and evaluating national and international cancer control policies. However, the collection of stage data by population-based cancer registries remains a challenge in both high-income and low and middle-income countries. ⋯ Flowcharts and rules have been developed for coding these elements in breast, cervix, prostate, and colon cancers, and combining them into stage groups (I-IV) that correspond to those obtained by full TNM staging. Essential TNM is comparable to the Union for International Cancer Control TNM stage groups and is an alternative to providing staging information by the population-based cancer registries that complies with the objectives of the Global Initiative for Cancer Registry Development.
