Experience with nasogastric tube administration of tirabrutinib in the treatment of an elderly patient with primary central nervous system lymphoma

We report that tirabrutinib was administered via nasogastric tubes to treat an elderly patient with primary central nervous system lymphoma (PCNSL). The patient was a 76-year-old woman who underwent endoscopic biopsy of multiple intracerebral masses, which resulted in the diagnosis of diffuse large B-cell lymphoma. The patient was diagnosed with PCNSL and was started on an induction regimen of systemic chemotherapy with rituximab in combination with high-dose methotrexate. However, after the second cycle of chemotherapy, the tumor grew rapidly, and the patient went into a coma. As a result, the treatment was changed to nasogastric tube administration of tirabrutinib suspension. After 1  week of tirabrutinib administration, the patient’s level of consciousness improved, and furthermore, after 2 weeks of tirabrutinib administration, the patient was able to take tirabrutinib orally. Although oral administration is the standard route of administration for tirabrutinib, this case s tudy showed that the nasogastric tube administration of tirabrutinib suspension is a therapeutic option for patients with impaired consciousness or dysphagia.
