Managing common toxicities associated with checkpoint inhibitor and chemotherapy combinations for untreated classic Hodgkin lymphoma.

Combination checkpoint inhibitor (CPI) and chemotherapy is an effective and safe treatment strategy for patients with untreated classic Hodgkin lymphoma. Recent studies of programmed cell death protein 1 inhibitors combined with doxorubicin, vinblastine and dacarbazine have demonstrated high overall and complete response rates. This combination has a unique toxicity profile that should be managed appropriately so as not to compromise treatment efficacy. Common toxicities include rash, hepatoxicity, neutropenia and thyroid dysfunction. Here, we present four cases and the management strategies around such toxicities. In addition, we highlight key clinical decision-making around the administration of subsequent doses of CPI and chemotherapy.
