Objectives

Narrative objectives1

The aim of this study is to understand the real-world treatment landscape of Pola-R-CHP therapy, one of the standard treatments for untreated diffuse large B-cell lymphoma (DLBCL), and to contribute to further safety measures. Specifically, this study will describe the incidence of febrile neutropenia (FN), anemia, and thrombocytopenia, as well as the reality of primary prophylactic administration of G-CSF preparations, by dividing the subjects into groups: those aged 80 and above and some other age categories. Additionally, the study will similarly describe the real-world situations of peripheral neuropathy (PN), constipation, and diarrhea.

To verify the validity of the results, this study will also examine the incidence of adverse events and the proportion of interventions in untreated DLBCL patients who have received R-CHOP therapy.

Assessment

Primary outcomes

During the 1st Pola-R-CHP therapy where untreated DLBCL patients are treated (for 6 cycles at most) followed by a 90-day safety assessment period, the following will be assessed for the overall population as well as by age group:
- the incidence of adverse events related to bone marrow suppression (FN), G-CSF prophylactic administration, and the proportion or cumulative incidence of interventions (such as transfusions for anemia and thrombocytopenia),
- calculation of the trend in the proportion of dose reductions of the medication (cyclophosphamide, polatuzumab vedotin, doxorubicin hydrochloride),
- and estimation of the distributions of the number of days and frequency of hospitalization.

Key secondary outcomes

First, in the R-CHOP group, the same items as in the Pola-R-CHP group will be evaluated.

Next, for untreated DLBCL patients receiving 1st line Pola-R-CHP or R-CHOP treatment (up to 6 cycles) + a maximum follow-up period of 90 days, the following will be conducted for both the overall population and by age group:
- estimation of the incidence of constipation, diarrhea, and PN requiring treatment,
- and calculation of the frequency of the number and types of medications used in the treatment of constipation and PN.

Furthermore, in each group or in the combined population, the following will be evaluated:
- the temporal trend in the incidence of FN,
- the proportion of days of prophylactic administration of G-CSF,
- the distribution of days of primary prophylactic administration of G-CSF in the first cycle,
- and the incidence of FN by age group and prophylaxis with G-CSF.

Key inclusion criteria

Patients must have a record of DLBCL (Diffuse Large B-Cell Lymphoma) during the patient enrollment period (from September 2022 to September 2023).

DLBCL: ICD-10 code C83.3 excluding "8847396 Primary Central Nervous System Diffuse Large B-Cell Lymphoma", or "8847326 Intravascular Large B-Cell Lymphoma" and "8847364 Mediastinal (Thymic) Large B-Cell Lymphoma". All records with a suspicious flag are not used.

Key exclusion criteria

The earliest day of prescription for R-CHOP or Pola-R-CHP is not included in the patient enrollment period.

No tests such as CD20 are performed prior to 60 days of the index date.

Index date: the first prescription day of the 1st line 1st cycle.
