Extranodal lymphomas constitute a heterogeneous group of malignancies, accounting for roughly 60% of all non-Hodgkin lymphomas. The extranodal organ where lymphomas arise is an important determining factor of biological, molecular, and aetio-pathogenic features, and of presentation, dissemination pattern, and outcome. An increased risk of CNS involvement, an uncommon but lethal event, has been suggested in some extranodal lymphomas, but the absolute risk is still debatable for most of these malignancies. ⋯ The identification of extranodal lymphomas at increased risk of CNS dissemination is an important unmet clinical need; affected patients could benefit from early CNS assessment by neuroimaging and cerebrospinal fluid analysis and adequate CNS prophylaxis, avoiding unnecessary prophylaxis and related toxicity in low-risk patients. This Review discusses relevant confounding factors and identifies high-risk extranodal lymphomas analysing histopathological category, involved organ, and other specific risk factors, which could be helpful for result interpretation and patient stratification in future clinical trials. Finally, a recommendation is provided for CNS-directed management of high-risk extranodal lymphoma patients in daily practice.

ReviewMicrobiota and radiation-induced bowel toxicity: lessons from inflammatory bowel disease for the radiation oncologist.
New gastrointestinal symptoms are frequent after pelvic radiotherapy and can greatly affect the quality of life of cancer survivors. The effect of radiation on the intestinal microbiota, and the clinical implications of a modified microbial balance after radiotherapy are now beginning to emerge. In this Personal View, we show the importance of the microbiota for intestinal homoeostasis, and discuss the similarity between inflammatory bowel disease, which has been extensively researched, and radiation-induced gastrointestinal toxicity. By use of microbiota profiles for risk assessment and manipulation of the intestinal flora for prevention and treatment of radiation, enteropathy could become a reality and would be of substantial relevance to the increasing numbers of long-term cancer survivors.

Review Meta AnalysisAccuracy of human papillomavirus testing on self-collected versus clinician-collected samples: a meta-analysis.
Screening for human papillomavirus (HPV) infection is more effective in reducing the incidence of cervical cancer than screening using Pap smears. Moreover, HPV testing can be done on a vaginal sample self-taken by a woman, which offers an opportunity to improve screening coverage. However, the clinical accuracy of HPV testing on self-samples is not well-known. We assessed whether HPV testing on self-collected samples is equivalent to HPV testing on samples collected by clinicians. ⋯ The 7th Framework Programme of the European Commission, the Belgian Foundation against Cancer, the International Agency for Research on Cancer, and the German Guideline Program in Oncology.

ReviewHealth-related quality of life in small-cell lung cancer: a systematic review on reporting of methods and clinical issues in randomised controlled trials.
Small-cell lung cancer represents about 15% of all lung cancers; increasingly, randomised controlled trials of this disease measure the health-related quality of life of patients. In this Systematic Review we assess the adequacy of reporting of health-related quality-of-life methods in randomised controlled trials of small-cell lung cancer, and the potential effect of this reporting on clinical decision making. Although overall reporting of health-related quality of life was acceptable, improvements are needed to optimise the use of health-related quality of life in randomised controlled trials.
