Anatomical laterality of primary intestinal diffuse large B-cell lymphoma independently stratifies survival: New prognostic nomogram incorporating tumor location

Key Points

• Survival is independently linked to intestinal laterality in primary intestinal diffuse large B-cell lymphoma, emphasizing its importance.
• The prognostic nomogram achieved higher discrimination than the International Prognostic Index, enhancing individual survival predictions.
• Risk stratification incorporates tumor location, allowing more tailored management approaches for patients.
• Findings support using anatomical factors in prognosis, though specific external validations are needed.
