Management of Advanced and Relapsed/Refractory Extranodal Natural Killer T-Cell Lymphoma: An Analysis of Stem Cell Transplantation and Chemotherapy Outcomes

We present a cohort of primarily non-Asian patients with advanced stage and relapsed/refractory ENKL. Our results demonstrate that achievement of complete response (CR) is imperative at all stages of disease in order to attain long-term disease control. The SMILE regimen was effective in relapsed/refractory disease to achieve complete remission. Autologous stem cell transplant should be strongly considered in patients with advanced ENKL who achieved CR, whereas allo-SCT can be considered for select patients who have not attained a CR.

Abstract BACKGROUND: Limited data are available regarding the incidence, survival patterns, and long-term outcomes of natural killer (NK)/T-cell neoplasms in the United States. PATIENTS AND METHODS: We performed a retrospective study of patients with NK/T-cell neoplasms diagnosed from 2001 to 2014 using the Surveillance, Epidemiology, and End Results program database. The Kaplan-Meier method was used to estimate the overall survival difference among the subgroups. Multivariate analyses were used to determine the factors affecting survival. RESULTS: For the 797 patients with NK/T-cell lymphoma, nasal type...

We performed a retrospective population-based study to determine the epidemiology of natural killer (NK)/T-cell neoplasms in the United States. We found that the incidence of NK/T-cell lymphoma doubled during the past decade and is more common in Hispanic population. Unlike NK/T-cell lymphoma, no significant racial disparities were found in NK/T-cell leukemia. The risk of second primary acute myeloid leukemia might be increased for patients with NK/T-cell lymphoma.

This was a retrospective population-based study aimed to determine the epidemiology of NK/T-cell neoplasms in the United States. We noticed that the incidence of NK/T-cell lymphoma doubled over the past decade and is more common in Hispanic population. Unlike NK/T-cell lymphoma, no significant racial disparities exist in NK/T-cell leukemia. There may be an increased risk of second primary acute myeloid leukemia (AML) in patients with NK/T-cell lymphoma.

Primary cutaneous lymphomas are a heterogeneous group of lymphoid malignancies and are the second most common group of extranodal non-Hodgkin lymphoma (NHL) following gastrointestinal lymphomas.1 NHL involving the female genitalia is unusual, posing diagnostic and therapeutic challenges.2-4 Rare cases of vulvar NHL presenting as a vulvar mass were mostly diagnosed as diffuse large B-cell lymphoma and had an aggressive course.3,5 Cases of cutaneous T-cell lymphoma (CTCL) involving the vulva have been rarely reported.

CD38 is highly and uniformly expressed on multiple myeloma (MM) cells, and at relatively low levels on normal lymphoid and myeloid cells, and in some tissues of nonhematopoietic origin. CD38 is a transmembrane glycoprotein with ectoenzymatic activity, and also functions as a receptor and adhesion molecule. Altogether, this has triggered the development of several CD38 antibodies including daratumumab (fully human), isatuximab (chimeric), and MOR202 (fully human). CD38 antibodies have pleiotropic mechanisms of action including Fc-dependent immune-effector mechanisms, direct apoptotic activity, and immunomodulatory effects b...

Conclusion Our results suggest that achievement of a CR is imperative in patients with advanced ENKL, and is desirable for any patient for whom auto-SCT is utilized. SMILE-based chemotherapy appeared effective in attaining a CR, and was also an effective salvage regimen. For patients attaining a first CR, auto-SCT should be strongly considered, but should definitely be utilized in patients attaining CR2. For patients with refractory disease, allo-SCT can be considered in a selected group of patients. Micro-Abstract We present a cohort of primarily non-Asian patients with advanced stage and relapsed/refractory ENKL. Our res...

Conclusion Allogeneic HSCT is a promising treatment modality for CD8+ PCAETL. Because of the aggressive nature of this disease and lack of sustained remission with currently available therapies, HSCT should be considered early in the course of treatment. Two novel agents, brentuximab and pralatrexate, showed significant activity against CD8+ PCAETL, and may be incorporated earlier in the treatment course. Micro-Abstract Several studies have suggested that hematopoietic stem cell transplantation (HSCT) might provide a cure for primary cutaneous aggressive epidermotropic cytotoxic CD8-positive T-cell lymphoma (CD8+ PCAETL). ...

We describe the clinicopathologic features of 17 patients who had a hematologic malignancy of various types, were treated, and subsequently developed a lymphoproliferative disorder (LPD). There were 10 men and 7 women with a median age of 59 years (range, 36 to 83 y). The primary hematologic neoplasms included: 5 chronic lymphocytic leukemia/small lymphocytic lymphoma, 3 plasma cell myeloma, 2 acute monoblastic leukemia, and 1 case each of mixed-phenotype acute leukemia, chronic myeloid leukemia, splenic marginal zone lymphoma, follicular lymphoma, mantle cell lymphoma, T-cell prolymphocytic leukemia, and peripheral...

Several studies have suggested that hematopoietic stem cell transplantation (HSCT) might provide a cure for primary cutaneous aggressive epidermotropic cytotoxic CD8-positive T-cell lymphoma (CD8+ PCAETL). We summarize published literature on this disease and present outcomes of 8 patients with CD8+ PCAETL treated at our institution. In our experience, allogeneic HSCT and the novel agents brentuximab and pralatrexate show substantial activity against this disease.
