Quality of life one year after chemoradiotherapy for localized primary gastric diffuse large B-cell lymphoma.

We assessed the quality of life (QOL) at least one year after sequential chemoradiotherapy for the treatment of localized gastric diffuse large B-cell lymphoma (DLBCL). We used the EORTC Quality of Life Questionnaire for Stomach Cancer (EORTC QLQ-STO22). Among the 45 patients available at the one-year follow-up after radiation therapy, 40 patients completed the EORTC QLQ-STO22 questionnaire. Their median age was 54.5 (range, 20-70 years). Social functioning was most adversely affected among the respondents with a score of 59, whereas other functions and the global scales were preserved above a score of 70 by linearly transformed values. Fatigue, the financial impact and specific emotional problems such as "thinking about their illness" (STO-ANX) and "worry about weight loss or future health" (STO-BI) were persistently bothersome for some patients. Other stomach-related symptoms such as dysphagia, pain, or reflux were negligible at 1 year after treatment. Therefore, this organ-preserving combined approach was effective for the maintenance of the QOL and minimization of stomach abnormalities in patients with gastric lymphoma.

CHOP followed by involved field radiotherapy for localized primary gastric diffuse large B-cell lymphoma: results of a multi center phase II study and quality of life evaluation.

We aimed to define the role of cyclophosphamide, vincristine, doxorubicin, prednisone (CHOP) followed by involved field radiotherapy (IFRT) for treating localized primary gastric diffuse large B-cell lymphoma (DLBCL). Newly diagnosed patients with localized primary gastric DLBCL were to receive four cycles of CHOP followed by IFRT of 40.0 Gy. At 1 year after the completion of treatment, patients filled out the EORTC Quality of Life Questionnaire specified for stomach cancer (QLQ-C30-STO22). Fifty evaluable patients (25 men, 25 women) were included. The median age was 54.5 years (range, 21 - 73 years. The overall response rate to the CHOP was 94% (95% confidence interval [CI], 87 - 100) in the intent-to-treat population. Forty-one of the 50 patients (82%; 95% CI, 71 - 93) achieved complete remission (CR). After the completion of radiotherapy, five patients who were in PR following chemotherapy eventually attained CR. The overall complete response rate was thus 92% (95% confidence interval, 84 - 99). With a median follow-up period of 30 months, the 2-year progression-free and overall survival rate was 92% and 92%, respectively. The gastric function was well preserved with negligible stomach-related symptoms at 1 year after the completion of treatment. This organ-preserving combined treatment is highly effective and well tolerated for the patients with localized gastric DLBCL.
