Abstract

In the era of immunochemotherapy, the traditional international prognostic index (IPI) has partially lost its predictive value in diffuse large B‑cell lymphoma (DLBCL) and the National Comprehensive Cancer Network‑IPI (NCCN‑IPI) is unable to effectively identify high‑risk patients. Thus, the present study aimed to develop a modified prognostic model (M‑PM) to identify high‑risk patients that require aggressive treatment. The present study included 169 patients with newly diagnosed DLBCL treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (RCHOP) or RCHOP‑like regimens, between 2011‑2017. The results demonstrated that the risk discrimination was improved in the NCCN‑IPI compared with the IPI, and patients were divided into four risk groups with a 5‑year overall survival rate of 93.8, 76.5, 54.3 and 39.4%, respectively. However, the NCCN‑IPI failed to identify the high‑risk DLBCL population. The newly developed M‑PM presented here included four parameters: Age (≥65 years), an elevated lactate dehydrogenase level, Eastern Cooperative Oncology Group score ≥2 and total metabolic tumor volume ≥300 cm3. The M‑PM also divided patients into four risk groups that comprised 40.8, 23.1, 26.0 and 10.1% of the patients, and the 5‑year survival rates of these groups were 92.4, 70.6, 52.3 and 24.5%, respectively. Taken together, the results of the present study demonstrated that the M‑PM was more accurate compared with the IPI and the NCCN‑IPI, which served as an effective tool for identifying patients with DLBCL at high risk of an adverse prognosis.
