A potential treatment option for elderly non-Hodgkin lymphoma patients with multiple comorbidities: Two case reports and literature review

Non-Hodgkin lymphoma (NHL) is a heterogeneous lymphoproliferative malignancy. More than half of the NHL cases occur in patients over 65 years of age. As elderly patients have a poor performance status and multiple comorbidities, the use of standard chemotherapy is often limited, leading to poor clinical outcomes and an increasing need for an alternate therapeutic modalities. A 73-year-old man was diagnosed with extranodal NK/T-cell lymphoma concurrently combined with recurrent gastric adenocarcinoma and metastatic prostate cancer. A 79-year-old woman was diagnosed with T-cell and B-cell dual-phenotype NHL on the right chest wall showing tumor thrombosis and multiple enlarged lymph nodes under chronic emphysema with extensive pleural calcification. Both elderly patients had multiple comorbidities and pathologically confirmed non-Hodgkin lymphoma. Both patients achieved tumor responses following anticancer treatment with Korean medicine (KM), suggesting that the extracts of Angelica gigas Nakai and Geopungtang are potential options for treating NHL in elderly patients with multiple comorbidities. Considering the clinical outcomes of KM treatment in the two elderly patients with NHL and multiple comorbidities, this study generates a research hypothesis for future prospective clinical studies in patients with NHL who are ineligible for conventional anticancer therapy.
