Follow-up Study of SyB L-0501 in Combination With Rituximab to Treat DLBCL

Study Overview
=================
Brief Summary
-----------------
This study is a follow-up study to update the survival time data (overall survival, progression-free survival, and duration of response) of the subjects who received SyB L-0501 at least once in Phase III Study of SyB L-0501 in combination with rituximab to treat recurrent/relapsed diffuse large B-cell lymphoma study (2017002) by reviewing their follow-up information following the study completion of Study 2017002. In this study, the follow-up information gathered until the end of the investigation period is reviewed after obtaining informed consent from the subjects or their legal representatives. Accordingly, no intervention, such as administration of the investigational product or examination, will be performed. Investigative methods The investigator or subinvestigator gives an explanation to a subject or his/her legal representative to obtain written informed consent to provision of information pertaining to this study. After obtaining informed consent, the investigator or subinvestigator reviews the follow-up information following the completion of Study 2017002 in source documents regarding the following items: 1. Survival status 2. Aggravation (progression or recurrence) 3. Drugs or procedures used for treatment of DLBCL or prophylaxis against its progression or recurrence 4. Occurrence of other malignant tumors
