Background: Wilms Tumor 1 (WT1) and Survivin genes are important leukemia-associated antigens (LAAs) in AML with potential prognostic impact.
Methods: We investigated WT1 and Survivin expression levels by RT-PCR in 61 AML patients in correlation with clinical characteristics and outcomes.
Results: WT1 was overexpressed in 45 patients (73.8%), associated with higher BM blasts (p = 0.017), lower incidence of favorable-prognosis cytogenetics (p = 0.035), and higher incidence of Flt3-ITD mutations (p = 0.026). Survivin was overexpressed in 17 patients (27.9%) with higher mean WBC count (p = 0.049). Patients with overexpression of either gene showed inferior complete remission (CR) rates and survival rates, patients with overexpression of both genes showed higher mean WBCs (p = 0.035) and higher BM blasts (p = 0.029) while the double negative group showed higher incidence of favorable cytogenetic events (p = 0.021), better CR rates and survival rates.
Conclusions: Our findings support the introduced prognostic impact of WT1 and Survivin genes in AML patients and its potential use in MRD monitoring and immunotherapy.

Background: Malignant pleural mesothelioma (MPM) poses diagnostic challenges due to its resemblance to benign pleural pathologies and different histological subtypes. Several immunohistochemistry markers have been employed to aid in accurate diagnosis.
Methods: The present systematic review and meta-analysis aimed to assess the diagnostic performance of various immunohistochemistry markers in malignant pleural mesothelioma diagnosis and its histological subtypes.

Patients with hematologic malignancies relapsing after allogeneic blood or marrow transplantation (BMT) have limited response to conventional salvage therapies, with an expected 1-year overall survival (OS) of <20%. We evaluated the safety and clinical outcomes following administration of a novel T-cell therapeutic targeting 3 tumor-associated antigens (TAA-T) in patients with acute leukemia who relapsed or were at high risk of relapse after allogeneic BMT. Lymphocytes obtained from the BMT donor were manufactured to target TAAs WT1, PRAME, and survivin, which are over-expressed and immunogenic in most hematologic malignancies.

Hematopoietic stem cell transplant (HSCT) is a curative option for patients with high-risk acute lymphoblastic leukemia (ALL), but relapse remains a major cause of treatment failure. To prevent disease relapse, we prepared and infused donor-derived multiple leukemia antigen-specific T cells (mLSTs) targeting PRAME, WT1, and survivin, which are leukemia-associated antigens frequently expressed in B- and T-ALL. Our goal was to maximize the graft-versus-leukemia effect while minimizing the risk of graft-versus-host disease (GVHD).

Patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) generally require allogeneic hematopoietic cell transplantation (allo-HCT) for a cure, except for patients with favorable genetic genotypes such as those with core-binding factor AML. However, the use of intensive chemotherapy followed by prompt HCT does not fully prevent relapse or refractory disease. Despite improvements in transplant techniques and management of complications, further improvement of HCT outcomes is urgently needed.

Hodgkin lymphoma (HL) Reed Sternberg cells express tumor-associated antigens (TAA) that are potential targets for cellular therapies. We recently demonstrated that TAA-specific T cells (TAA-Ts) targeting WT1, PRAME, and Survivin were safe and associated with prolonged time to progression in solid tumors. Hence, we evaluated whether TAA-Ts when given alone or with nivolumab were safe and could elicit antitumor effects in vivo in patients with relapsed/refractory (r/r) HL.
