What the trial was testing
The MARIETTA enrolled 79 patients with lymphoma. The study was sponsored by International Extranodal Lymphoma Study Group (IELSG) and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
58% of patients were cancer-free one year after treatment with this intensive approach.

These findings — that more than half remained cancer-free a year after intensive treatment — were published in the The Lancet. Haematology and represent the headline result of the study.
Researchers tracked outcomes across 79 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with lymphoma, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This was mid-stage testing and the specific combination is not yet standard care. If you have lymphoma that has spread to your central nervous system, ask your doctor about clinical trials or similar intensive treatments. This condition requires urgent specialist care.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Quality of Life in Cutaneous Lymphoma Patients Using the Skindex29
This study assesses the quality of life in patients with cutaneous lymphoma diagnosis as it relates to their personal, clinical, and therapeutic information using the Skindex29 questionnaire and also assesses patients' understanding of their diagnosis and need for resources related to their care. Cutaneous lymphomas are a rare type of blood cancers (non-Hodgkin lymphoma) that present in the skin. The information gained from this study, may help researchers improve quality of life in cutaneous lymphoma patients.
R-CDOP Combined With Intrathecal Methotrexate for DLBCL Patients With High-risk of CNS Relapse
This is a double-center, single-arm, phase 2 study to evaluate the efficacy and safety of R-CDOP regimen combined with intrathecal methotrexate in chemo-naive diffuse large B-cell lymphoma patients with high-risk of CNS relapse.
