Background. The increasing incidence of cancer combined with prolonged survival times seen throughout the western world increases the need for rehabilitation. Diagnosis and treatment for cancer may have substantial effects on the patients' physical, psychological, social and existential well-being. The aim of this paper is to describe the current situation in cancer rehabilitation in the Nordic countries, the Netherlands and Germany. Material and methods. Description of the current situation in cancer rehabilitation in the Nordic countries and literature review. Results. Rehabilitation as defined by multiple organizations covers a multidimensional view on chronic disease and its effect on the patient's life. The rehabilitation systems in Denmark, Finland, Sweden, Germany and the Netherlands differ depending on the differing social security and health-care systems, but rehabilitation provided is largely based on a similar, multidimensional and multidisciplinary understanding of cancer rehabilitation. Research on rehabilitation efforts in European countries indicates that there is substantial evidence with regard to single interventions which can be part of cancer rehabilitation. Discussion. In order to assure patients and families continuing quality of life, rehabilitation should be an integral and continuous part of all cancer care. [ABSTRACT FROM AUTHOR]

The article focuses on the diagnosis of locally recurrent head and neck squamous cell carcinoma (LRC) in Nordic Head and Neck Cancer (HNC) centers and the feasibility of using the Odense-Birmingham definition for uniform diagnosis. Topics discussed include the variation in clinical practice for classifying LRC versus second primary carcinoma (SPC) and the impact of introducing the Odense-Birmingham definition on diagnostic decisions among HNC specialists.

The stage at diagnosis is one of the most important predictors for cancer survival. TNM stage is constructed from T (tumor size), N (nodal spread), and M (distant metastasis) components. In many notifications to cancer registries, TNM information is incomplete with unknown N and/or M. We aimed to evaluate the influence of various assumptions for recoding missing N (NX) and M (MX) as N0 and M0 on the proportion with available TNM stage, stage-distribution, and stage-specific relative survival. We identified 140,201 patients diagnosed with incident cancer of the colon, rectum, lung, breast, or kidney during 2014–2016 in Denmark, Norway, Sweden, or Iceland. Information on TNM were obtained from cancer registry records used for an update of the Nordic cancer statistics database NORDCAN. Patients were followed for death or emigration through 2017. We calculated proportions of available TNM stage, stage distribution, and stage-specific relative survival under different approaches for each cancer site and country. Application of the assumptions yielded higher numbers of cases with available TNM stage for stages 0–I, II, and III. We observed only minor differences in stage-specific one-year relative survival when applying N0M0 for missing N and M, especially for high completeness of TNM registrations, whereas relative survival for remaining cases with missing TNM stage declined substantially. We found no major changes in stage-specific one-year relative survival applying N0M0 for NXMX. We conclude that complete TNM information is preferable to making assumptions, but it seems reasonable to consider assuming N0M0 for missing N and M in future studies based on the Nordic cancer registries. An automatic algorithm, though, is not recommended without considering potential area-specific reasons for frequent use of NX and MX. Clinicians should be urged to report complete TNM information to improve surveillance of the TNM stage. [ABSTRACT FROM AUTHOR]
