Additional comments
Ongeveer 70 patiënten worden behandeld in de tweede lijn voor gemetastaseerd adenocarcinoom van de maag of gastro-oesofageale overgang. Het aantal patiënten met een slokdarmcarcinoom die in de tweede lijn worden behandeld bedraagt ongeveer 60. In totaal zijn dit dus 130 patiënten. De inschatting is dat hiervan maximaal 60% een derdelijns behandeling krijgt (78 patiënten).
