PRAME over-expression in gynecological tumors supports the notion that this marker should not be regarded as specific to MM alone. EC exhibited higher PRAME expression than CC and OC, and low-grade EEC displayed higher PRAME immunoreactivity than other EC types. Our findings suggest that PRAME immunostaining can be useful to distinguish EEC from ovarian endometrioid carcinoma and endocervical adenocarcinoma. PRAME over-expression can also help differentiate non-aggressive EC from aggressive EC.

In patients with heavily pretreated T-cell lymphoma, CTX130 showed manageable safety and a promising objective response rate. This study shows that allogeneic, readily available CAR T cells can be safely given to patients with relapsed or refractory T-cell lymphoma. A next-generation CAR T-cell therapy containing additional potency gene edits (CTX131) is in clinical development.

The PRAME has significance in discriminating the conjunctival malignant melanoma and pigmented nevus. It is a useful biomarker in the diagnosis of conjunctival malignant melanoma.

BIMT are more common in a sporadic setting and behave indolently, despite worrying cytological atypia. PRAME immunohistochemistry is a reassuring tool in distinguishing BIMT from melanoma.

GEP, NGS, and PRAME expression analysis help determine different levels of metastatic risk in UM. Although other prognostic tests exist, the following study reports on the use of NGS for metastatic prognostication in UM. However, limitations of NGS exist, especially with small lesions that are technically difficult to biopsy.

PRAME is a useful marker for the diagnosis of melanoma in cytology material, but it is less sensitive than SOX10. PRAME is also expressed in other nonmelanocytic tumors which limits its specificity.

GEP agreed with the final diagnosis in 88% of cases with a sensitivity of 65%, 97% specificity, and positively predicted melanoma in 91.7% of cases. Because the results of this study align with past publications evaluating the performance metrics of PRAME IHC, showing it to be as sensitive as and more cost effective than all other ancillary molecular tests, we propose the use of PRAME IHC as the optimal first-line diagnostic tool for ambiguous melanocytic proliferations.

Therefore, PRAME expression may serve as a useful marker for CIS of the urinary tract. Furthermore, PRAME may be a candidate for the novel therapeutic target for standard treatment-refractory CIS patients.

Our results further support PRAME overexpression in gynecologic cancers, including CS with similar expression levels in epithelial and mesenchymal components. PRAME might have a role in epithelial-mesenchymal transition in this group of cancers.

Oral azacytidine may be used as maintenance treatment in AML in first remission, but can be associated with substantial side effects, and less toxic strategies should be explored. OS at five years was 75% (95% CI: 50-89), with 70% of patients ≥60 years of age being long-term survivors. Maintenance therapy with this DC vaccine was well tolerated in AML patients in CR1 and was accompanied by encouraging 5-year long-term survival.

Early results indicate that the antigen-specific NEXI-001 T cells have the potential to enhance GvL effects and is tolerated with easily manageable side effects. Greater clinical activity has been observed with increased doses of the NEXI-001 T cells. The trial remains ongoing, and the data support an Expansion Cohort of the study that will allow for a more complete assessment of clinical activity.

Among tumors with retained BAP1 staining, PRAME positivity was associated with shorter MFS and DSS (P = .001 and P = .021, respectively). In summary, a combination of BAP1 and PRAME IHC can be used for risk stratification of UMs.

This means a better differential diagnosis, a reliable early diagnosis and a proper clinical/surgical management of the oncological lesions. In conclusion, PRAME can be a valid qualitative marker for differential diagnosis, not only in cutaneous melanomas, but also in malignant melanoma of the entire head and neck area.

Moreover, PRAME played the role at least partially by activating PI3K/AKT/mTOR pathways. The above findings elucidate that PRAME may be a valuable oncogene target, contributing to the diagnosis and therapy of LSCC.
