Tolerability and efficacy of rituximab-containing immunochemotherapy in patients with B-cell non-Hodgkin lymphoma receiving hemodialysis

Hodgkin Lymphoma on Hemodialysis: A Review of Treatment and Recommendations

Chemotherapy for classic Hodgkin lymphoma (cHL) patients on hemodialysis (HD) is an extremely challenging situation because pharmacokinetic and pharmacodynamic studies of most chemotherapeutics are lacking for the HD patient, and the small amount of evidence available comes mostly from case reports and small case series. In this review, we provide recommendations based on treatment experience of cHL patients on HD in the literature. HD patients undergoing chemotherapy are at risk of overdose and toxicities because many drugs are significantly eliminated by the kidneys, and at the same time, are at risk of undertreatment because many drugs are removed by HD. Therefore, dose modifications and timing of drug administration in relation to HD sessions must be carefully planned according to the distinct traits of each chemotherapeutic. We carried out an exhaustive literature review of reports of actual administrations of chemotherapeutics to cHL on HD, and also extrapolated data from reports of the same chemotherapeutics that were administered to HD patients with malignancies other than cHL. We summarized the information found in the literature, and provide practical and balanced recommendations concerning dose modifications and optimal timing of drug administration in relation to HD sessions for each chemotherapeutic. Chemotherapy regimens and individual chemotherapeutics studied in this review include ABVD (doxorubicin + bleomycin + vinblastine + dacarbazine), BEACOPP (bleomycin + etoposide + doxorubicin + cyclophosphamide + vincristine + procarbazine + prednisolone), MOPP (mechlorethamine + vincristine + procarbazine + prednisolone), gemcitabine, vinorelbine, brentuximab vedotin, and PD-1 inhibitors (nivolumab and pembrolizumab).

Chemotherapy for non-Hodgkin lymphoma in the hemodialysis patient: A comprehensive review

Chemotherapy for non-Hodgkin lymphoma (NHL) in the hemodialysis (HD) patient is a challenging situation. Because many drugs are predominantly eliminated by the kidneys, chemotherapy in the HD patient requires special considerations concerning dose adjustments to avoid overdose and toxicities. Conversely, some drugs are removed by HD and may expose the patient to undertreatment, therefore the timing of drug administration in relation to HD sessions must be carefully planned. Also, the metabolites of some drugs show different toxicities and dialysability as compared with the parent drug, therefore this must also be catered for. However, the pharmacokinetics of many chemotherapeutics and their metabolites in HD patients are unknown, and the fact that NHL patients are often treated with distinct multiagent chemotherapy regimens makes the situation more complicated. In a realm where uncertainty prevails, case reports and case series reporting on actual treatment and outcomes are extremely valuable and can aid physicians in decision making from drug selection to dosing. We carried out an exhaustive review of the literature and adopted 48 manuscripts consisting of 66 HD patients undergoing 71 chemotherapy regimens for NHL, summarized the data, and provide recommendations concerning dose adjustments and timing of administration for individual chemotherapeutics where possible. The chemotherapy regimens studied in this review include, but are not limited to, rituximab, cyclophosphamide + vincristine + prednisolone (CVP) and cyclophosphamide + doxorubicin + vincristine + prednisolone (CHOP)-like regimens, chlorambucil, ibrutinib, bendamustine, methotrexate, platinum compounds, cytarabine, gemcitabine, etoposide, ifosfamide, melphalan, busulfan, fludarabine, mogamulizumab, brentuximab vedotin, and 90 Y-ibritumomab tiuxetan.

Rituximab use for lymphoplasmacytic lymphoma during continuous renal replacement therapy

Rituximab safety and efficacy in patients with renal impairment have not been established, nor have the effects of hemodialysis on serum rituximab level. There are only a few published case reports assessing serum rituximab level pre- and postdialysis. No data have been published regarding the usage of rituximab in patients with continuous renal replacement therapy. The authors present a case of a 59-year-old female patient who presented with paraneoplastic tetraparesis. She was admitted to the intensive care unit due to alveolar hemorrhage with respiratory failure and acute kidney injury requiring continuous renal replacement therapy. After a diagnostic workup, the diagnosis of lymphoplasmacytic lymphoma was established. Therapy with rituximab and cyclophosphamide was started. Rituximab levels were determined in serum and dialysate. No rituximab was found in the dialysate. The patient died after 2 months in the intensive care unit from nosocomial pneumonia due to multidrug-resistant Pseudomonas aeruginosa.
