Anaplastic lymphoma kinase positive (ALK+) anaplastic large cell lymphoma (ALCL) typically affects young individuals and, despite high responsiveness to cytotoxic drugs, relapses occur in over 50% of patients. Crizotinib has improved outcomes, but its management in patients desiring parenthood remains an issue. This study presents the first description of four successful pregnancies during crizotinib treatment for ALK+ALCL: a female patient achieving two pregnancies through assisted reproductive technologies (ART), temporarily discontinuing crizotinib and maintaining a complete remission (CR), and a male patient conceiving naturally while on continuous therapy. These cases demonstrate crizotinib potential to support conception without compromising disease control, even in the absence of specific guidelines on treatment discontinuation.
