The third-generation anti-CD30 CAR T-cells specifically homing to the tumor and mediating powerful antitumor activity.

Sci Rep 2022 Jun 21;12(1):10488. Epub 2022 Jun 21.

Institute of Biology and Medicine, College of Life and Health Sciences, Wuhan University of Science and Technology, Hubei, 430081, China.

CAR T-cell therapy is well tolerated and effective in patients with Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL). However, even second- generation anti-CD30 CAR T-cells with CD28 (28z) costimulatory domains failed to achieve the desired rate of complete responses. In the present study, we developed second-generation (CD28z) and third-generation (CD28BBz) CAR T-cells targeting CD30 and investigated their efficacy in vitro and in vivo. Read More

Cost-effectiveness of brentuximab vedotin plus chemotherapy for previously untreated CD30-positive peripheral T-cell lymphoma in Canada.

J Med Econ 2022 Jan-Dec;25(1):324-333

Health Economics Outcomes Research, Seagen Inc., Bothell, WA, USA.

Aims: To support reimbursement requests in Canada, we evaluated the cost-effectiveness of brentuximab vedotin (Adcetris) in combination with cyclophosphamide, doxorubicin, and prednisone (A + CHP) compared with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) as frontline treatment for CD30-expressing peripheral T-cell lymphomas (PTCLs) using results from the ECHELON-2 clinical trial. The PTCL subtypes included were systemic anaplastic large cell lymphoma (sALCL), PTCL-not otherwise specified (PTCL-NOS), and angioimmunoblastic T-cell lymphoma (AITL).

Materials And Methods: A partitioned survival model consisting of three health states (progression-free survival [PFS], post-progression survival [PPS], and death) was constructed from the perspective of the Canadian publicly funded healthcare system over a lifetime horizon. Read More

Utility of a new notation to visualize flow cytometry analysis results: first preliminary comparison with immunohistochemistry to detect CD30 expression on T-cell lymphoma cells.

BMC Cancer 2021 Dec 20;21(1):1352. Epub 2021 Dec 20.

Division of Hematopathology, Tohoku University Hospital, 1-1 Seiryo-machi, Aoba-ku, Sendai, 980-8574, Japan.

Background: It is important to confirm CD30 expression in T-cell lymphoma cases, but immunohistochemical staining for CD30 is not commonly performed and no comparison has been done between the results of flow cytometry (FCM) and immunohistochemical staining for CD30. Therefore, we devised a notation that we termed proportion of immunoreactivity/expression for FCM (PRIME-F notation), based on the cellular proportion showing different antigen-antibody reactivity.

Methods: We retrospectively compiled 211 cases of T-cell lymphoma, assessed via FCM, from major hospitals in Miyagi Prefecture from January 2012 to January 2019, and compared 52 of these cases with the immunohistochemical immunoreactive (IR) pattern of CD30 (PRIME-I notation). Read More

The ECHELON-2 Trial: 5-year results of a randomized, phase III study of brentuximab vedotin with chemotherapy for CD30-positive peripheral T-cell lymphoma.

Ann Oncol 2022 03 16;33(3):288-298. Epub 2021 Dec 16.

Division of Cancer Sciences, Faculty of Biology, Medicine and Health, University of Manchester, NIHR Biomedical Research Centre, Manchester Academic Health Sciences Centre, Christie Hospital NHS Foundation Trust, Manchester, UK.

Background: For patients with peripheral T-cell lymphoma (PTCL), outcomes using frontline treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like therapy are typically poor. The ECHELON-2 study demonstrated that brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A+CHP) exhibited statistically superior progression-free survival (PFS) per independent central review and improvements in overall survival versus CHOP for the frontline treatment of patients with systemic anaplastic large cell lymphoma or other CD30-positive PTCL.

Patients And Methods: ECHELON-2 is a double-blind, double-dummy, randomized, placebo-controlled, active-comparator phase III study. Read More

BIA-ALCL diagnosis on CytoLyt fixed ThinPrep, cell block and immunohistochemistry.

Diagn Cytopathol 2022 Jan 8;50(1):E1-E5. Epub 2021 Oct 8.

Department of Pathology and Cell Biology, Columbia University, New York City, New York, USA.

Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is an emergent rare T cell non-Hodgkin lymphoma arising in association with a breast implant, particularly textured ones. Recent guidelines list cytopathological examination as the first essential step for diagnosis, routinely followed by CD30 immunohistochemistry (IHC) and flow cytometry (FC) for a T cell clone. The majority of BIA-ALCL literature regarding cytopathological evaluation describes morphology based on various preparation methods limited to cytospins and smears with the exception of at least one case report detailing cytomorphological and IHC findings on ThinPrep.

Super-enhancer-based identification of a BATF3/IL-2R-module reveals vulnerabilities in anaplastic large cell lymphoma.

Nat Commun 2021 09 22;12(1):5577. Epub 2021 Sep 22.

Division of Haematopathology, European Institute of Oncology IRCCS, Milan, Italy.

Anaplastic large cell lymphoma (ALCL), an aggressive CD30-positive T-cell lymphoma, comprises systemic anaplastic lymphoma kinase (ALK)-positive, and ALK-negative, primary cutaneous and breast implant-associated ALCL. Prognosis of some ALCL subgroups is still unsatisfactory, and already in second line effective treatment options are lacking. To identify genes defining ALCL cell state and dependencies, we here characterize super-enhancer regions by genome-wide H3K27ac ChIP-seq. Read More

Better method for detection of CD30: Immunohistochemistry or flow cytometry?

J Clin Exp Hematop 2021 Dec 10;61(4):221-223. Epub 2021 Sep 10.

Department of Pathology, Saitama Medical Center, Saitama Medical University, Saitama, Japan.

We compared the two methods of assessing CD30 protein expression in DLBCL and TCL specimens routinely employed at our hospital, immunohistochemistry (IHC) and flow cytometry (FCM), using the same clone of the anti-CD30 antibody (Ber-H2) in 123 patients with DLBCL and 28 patients with TCL. FCM was more sensitive than IHC, especially in cases with low expression. In three cases of TCL and two cases of DLBCL, there was discordance between these two methods. Read More

ALK-negative anaplastic large cell lymphoma, null type with aberrant expression of PAX5 and CD138: A diagnostic pitfall.

Diagn Cytopathol 2021 Oct 30;49(10):E395-E399. Epub 2021 Jun 30.

Department of Pathology and Laboratory Medicine, Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Hempstead, New York, USA.

A 72-year-old man was found to have generalized lymphadenopathy, splenomegaly, and elevated serum lactate dehydrogenase. Fine-needle aspiration and core needle biopsy of a cervical lymph node revealed a large lymphoid cell proliferation with features suggestive of anaplastic large cell lymphoma (ALCL). However, immunophenotypically, the neoplastic cells expressed PAX5 and CD138 in addition to CD30, CD45, MUM-1 and were negative for T-cell markers, B-cell markers, CD15, ALK-1, HHV-8, EBER, kappa, lambda, and pancytokeratin.

What's new in peripheral T-cell lymphomas.

Hematol Oncol 2021 Jun;39 Suppl 1:52-60

Surgical, Medical and Dental Morphological Sciences Related to Transplant, Oncology and Regenerative Medicine, University of Modena and Reggio Emilia, Reggio Emilia, Italy.

Peripheral T-cell lymphomas (PTCLs) are a rare, heterogeneous group of hematological malignancies with extremely poor prognosis for almost all subtypes. The diverse clinicopathological features of PTCLs make accurate diagnosis, prognosis, and choice of optimal treatment strategies difficult. Moreover, the best therapeutic algorithms are still under debate due to the extrapolated approaches developed for B-cell lymphomas and to the absence of few treatment protocol specifically developed for PTCLs.

JAK2 Rearrangements Are a Recurrent Alteration in CD30+ Systemic T-Cell Lymphomas With Anaplastic Morphology.

Am J Surg Pathol 2021 07;45(7):895-904

Department of Pathology, Massachusetts General Hospital, Harvard Medical School.

Peripheral T-cell lymphoma (PTCL) comprises a heterogenous group of rare mature T-cell neoplasms. While some PTCL subtypes are well-characterized by histology, immunophenotype, and recurrent molecular alterations, others remain incompletely defined. In particular, the distinction between CD30+ PTCL, not otherwise specified and anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma can be subject to disagreement. Read More

Aesthet Surg J 2022 01;42(2):NP125-NP129

Department of Medicine, Brown University Alpert Medical School, Providence, RI, USA.

CD30 lymphocyte activation antigen and phosphorylated STAT3 (pSTAT3) are consistent markers of tumor cells in breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). We present a case of BIA-ALCL in a breast implant capsule containing clustered tumor cells expressing CD30, pSTAT3, pSTAT6, interleukin 9, and granzyme B tumor cell biomarkers. Remarkably, the contralateral breast contained many scattered large, atypical CD30+ cells surrounded by inflammatory cells, raising a suspicion of bilateral BIA-ALCL, known to occur in some patients.

Pediatric primary cutaneous anaplastic large cell lymphoma treated with brachytherapy.

Pediatr Dermatol 2021 May 19;38(3):712-713. Epub 2021 Mar 19.

Dermatology Program, Boston Children's Hospital, Boston, MA, USA.

Primary cutaneous anaplastic large cell lymphoma (PC-ALCL) is a CD30+ lymphoproliferative disorder that rarely occurs in children. Although there are currently no consensus guidelines for the treatment of cutaneous lymphoma in the pediatric population, the isolated form of PC-ALCL is typically managed by surgical excision or external beam radiation therapy. We report the case of a 6-year-old girl with primary cutaneous anaplastic large cell lymphoma that was treated with brachytherapy with no recurrence after 21 months of follow-up, suggesting that brachytherapy may be considered as a treatment for pediatric cutaneous large cell anaplastic lymphoma.

Is immunohistochemical expression of GATA3 helpful in the differential diagnosis of transformed mycosis fungoides and primary cutaneous CD30-positive T cell lymphoproliferative disorders?

Virchows Arch 2021 Aug 18;479(2):377-383. Epub 2021 Feb 18.

Department of Pathology, Dermatopathology Section, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Mycosis fungoides with large cell transformation (MFLCT) can be difficult to distinguish from primary cutaneous CD30+ T cell lymphoproliferative disorders (PC CD30+ LPD), especially primary cutaneous anaplastic large cell lymphoma (PC-ALCL). This diagnostic distinction is critical for appropriate patient management. GATA3 has been proposed to be useful in the discrimination between these two entities. Read More

A case of lymphomatoid papulosis type E in a young adult: An uncommon entity.

J Cutan Pathol 2021 May 18;48(5):694-700. Epub 2021 Feb 18.

Department of Dermatology, Boston University School of Medicine, Boston, Massachusetts, USA.

Lymphomatoid papulosis (LyP) type E is a rare variant of the primary cutaneous CD30+ lymphoproliferative disorders, characterized clinically by large necrotic eschar-like lesions and histopathologically by angiodestructive and angioinvasive infiltrates of CD30+ lymphocytes. As in other forms of lymphomatoid papulosis, type E lesions may undergo spontaneous regression after weeks, with frequent recurrences. We report a 21-year old male with an angiodestructive infiltrate of CD30+ lymphocytes manifesting as a papular eruption rather than ulceration, and suggest that this clinical phenotype might be related to the presence of CD4+ lymphocytes in the inflammatory cell infiltrate.
