Current treatment modalities can cure up to 70-80 % of patients with classical Hodgkin lymphoma. Approximately, 20-30 % of patients require further treatment options. Brentuximab vedotin has been approved for the treatment of relapsed and refractory Hodgkin lymphoma. In the present study, we report the experience with brentuximab vedotin as single agent in 58 patients with relapsed or refractory Hodgkin lymphoma. The objective response rate was 63.5 % with 13 complete responders (26.5 %) among 49 patients evaluated at the early phase of treatment (2-5 cycles). Upon treatment prolongation (a parts per thousand yen6 cycles), 37 patients achieved a final objective response rate of 32.4 % with 21.6 % of complete and 10.8 % of partial response. Overall survival at 12 months was 70.6 %, and progression-free survival at 12 months was 32.8 %. Median overall survival could not be reached and median progression-free survival was 7 months. While the median duration of response was 9 months in the whole cohort, it was 11.5 months in the complete responders. Complete response rates in patients treated with > 3 chemotherapy regimens before brentuximab vedotin were significantly lower (p = 0.016). Fourteen patients were subsequently transplanted. In conclusion, brentuximab vedotin provided a bridge to transplantation in approximately one quarter of the patients. The declining response rates during the course of treatment suggest that transplantation should be implemented early during brentuximab vedotin treatment.

Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, approximately one-third of responders experience disease relapse following first-line therapy. Several studies have shown the efficacy of brentuximab vedotin (BV) in patients with relapsed/refractory HL. We present a retrospective analysis of 58 patients with relapsed/refractory HL treated with BV in a named patient program from 11 centers. The median follow-up duration was 20 (range, 4-84) months. The best overall response rate was 64% (complete response [CR], 31%; partial response [PR], 33%). The 5-year progression-free survival (PFS) and overall survival (OS) rates were 12% (95% confidence interval [CI], 0.05-0.22) and 26% (95% CI, 0.16-0.38), respectively. Among patients who achieved CR, the estimated 5-year PFS and OS rates were 32% (95% CI, 0.13-0.54) and 60% (95% CI, 0.33-0.78), respectively. A total of 26 patients underwent subsequent stem cell transplantation. The 5-year PFS and OS rates for 10 patients who had consolidative stem cell transplantation were 28% and 30%, respectively. Twenty-seven patients required further therapy following BV. At the time of the analysis, 12 patients (21%) were alive. Five patients (9%) had long-term remission after achieving CR with BV monotherapy, with a median PFS of 76 months. Three of them (5%) did not receive any other treatment following BV and their median PFS was 75 months. Our long-term results showed that a small subset of patients with relapsed/refractory cHL may benefit from and even be cured with BV monotherapy.

Purpose In the ToGA trial for HER2-positive advanced gastric cancer, cisplatin plus fluoropyrimidine was given for 6 cycles; trastuzumab was given until disease progression. However, there is a lack of real-life data about trastuzumab maintenance after 6 cycle chemotherapy. This study aims to present real-life data of trastuzumab +/- capecitabine maintenance after 6 cycles of platinum, fluoropyrimidine, and trastuzumab in non-progressive patients. Methods This is a retrospective multicenter study of the Turkish Oncology Group. A total of 35 HER2-positive, inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma patients being non-progressive at the end of 6 cycle chemotherapy and being given trastuzumab +/- capecitabine as maintenance treatment were included from sixteen oncology centers. Baseline characteristics, objective tumor responses, progression free and overall survival data, and toxicities were determined. Results About 68% of the patients were given CF, and 32% were given FOLFOX with trastuzumab as the first-line treatment. The best response in 6 cycle chemotherapy was complete 8 (22%), partial 24 (68%), and stable disease 3 (8%). All patients had trastuzumab maintenance (median cycle 13; range 7-51), and 49% of the patients had capecitabine with trastuzumab (median capecitabine cycle 6; range 2-30). The median PFS of the patients was 12.0 months (95% CI 10.3-13.7), and median OS was 17.4 months (95% CI 15.2-19.5). There were 2 patients with grade 1 cardiotoxicity. Conclusion Trastuzumab maintenance +/- capecitabine after 6 cycles of trastuzumab plus combined chemotherapy treatment revealed efficacy and safety in non-progressive HER2-positive advanced gastric cancer.
