7 juni 2017: omdat ik inhoudelijk alles alleen doe ben ik nog niet toegekomen aan de meeste van deze studies. Enkele wel die zijn verwerkt in onze nieuwsbrief van 7 juni 2017, maar ik wil het zorgvuldig doen en er soms ook bijbehorende informatie bij zoeken. En dat kost gewoon heel veel tijd.

Maar Cancer Research heeft alle studies die te maken hebben met immuuntherapie geselecteerd met link naar abstract. Ik heb hun lijst gekopieerd en per kankersoort ingedeeld op alfabetische volgorde volgens Nederlandse namen:
