We analyzed the effects of the initial approach to patients with follicular lymphoma (FL) on outcomes in order to investigate whether the watch and wait (WW) strategy is still an acceptable approach in the rituximab era. We retrospectively analyzed 348 patients who were initially diagnosed with FL between 2000 and 2012. We compared the clinical outcomes of the WW cohort and immediate treatment cohort. Among 348 patients (median age of 57 years, range: 19–85), 101 were initially managed with WW and 247 were immediately treated. The median follow-up duration was 75 months (range: 7–169). The estimated median time to treatment failure (TTF) in the treatment following WW cohort and immediate treatment cohort were 92 months (95 % CI, 60.1–NA) and 77 months (95 % CI, 65.1–107.6), respectively, which were not significantly different (P = 0.272) . In a multivariate analysis, clinical stage was identified as a predictive factor of TTF (HR 1.19, 95 % CI, 1.03–1.38, P < 0.05). Neither overall survival rate nor cumulative risk of transformation between the WW cohort and immediate treatment cohort was significant. The results of the present study suggested that the WW strategy is still an acceptable approach for selected FL patients in the rituximab era.
The clinical significance of extramedullary relapse (EMR) of acute myelogenous leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains poorly defined. Here we report the clinical outcomes of patients who underwent allo-HSCT for AML at our institution between 2000 and 2012. A total of 293 patients with AML who underwent allo-HSCT were included. The median duration of follow-up in survivors was 1840 days. Disease status at the time of allo-HSCT was complete remission in 192 patients and nonremission in 101 patients. A total of 110 patients experienced AML relapse after allo-HSCT, including 18 with EMR only, 83 with bone marrow relapse (BMR) only, and 9 with both EMR and BMR. The 5-year cumulative incidence of EMR after allo-HSCT was 9.5%, whereas that of BMR only was 28.9%. In multivariate analysis, peripheral blood stem cell transplantation was associated with an increased risk of EMR. The 2-year overall survival after post-transplantation relapse was 7.5% in patients with BMR only, 11.1% in those with both EMR and BMR, and 27.5% in those with EMR only (P < .05). Although the short-term survival was better in patients with EMR only, they rarely achieved long-term survival. Appropriate strategies for both post-transplantation EMR and BMR are needed.
Paraneoplastic pemphigus (PNP) is a severe autoimmune blistering disease associated with an underlying malignancy, and its prognosis is poor. We herein report the first patient with B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (B-CLL/SLL)-associated PNP successfully treated with the Bruton's tyrosine kinase inhibitor ibrutinib and rituximab. Although his PNP lesions did not improve with ibrutinib monotherapy, the combination of ibrutinib and rituximab was effective against B-CLL/SLL-associated PNP. This case suggests that ibrutinib plus rituximab may be a potent therapeutic option for B-CLL/SLL-associated PNP that is hard to control with ibrutinib alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
