Despite treatment advances through immunotherapies, including anti-PD-1/PD-L1 therapies, the overall prognosis of non-small cell lung cancer (NSCLC) patients remains poor, underscoring the need for novel approaches that offer long-term clinical benefit. This review examined the literature on the subject over the past 20 years to provide an update on the evolving landscape of dendritic cell-based immunotherapy to treat NSCLC, highlighting the crucial role of dendritic cells (DCs) in immune response initiation and regulation. These cells encompass heterogeneous subsets like cDC1s, cDC2s, and pDCs, capable of shaping antigen presentation and influencing T cell activation through the balance between the Th1, Th2, and Th17 profiles and the activation of regulatory T lymphocytes (Treg).

Article Synopsis
  • High-grade astrocytoma with piloid features (HGAP) is a newly identified glioma type classified by its unique global epigenetic signature and commonly associated with mutations in the MAPK pathway and other genetic alterations like CDKN2A/B deletions and ATRX mutations.
  • A study involving 144 patients with HGAP confirmed frequent CDKN2A/B deletions, ATRX mutations, and noted some cases with TP53 mutations or NTRK2 gene fusions, the latter being previously unreported.
  • Analysis revealed three distinct subtypes of HGAP based on DNA methylation patterns, with subtype gNF1 associated with Neurofibromatosis Type 1, specific tumor characteristics, and a potential trend towards

The archetypal solitary fibrous tumor (SFT) features fibroblastic cells with varying cellularity without any particular architectural arrangement in a collagenous matrix, with staghorn vessels, CD34 and STAT6 expression, and NAB2::STAT6. To date, this fusion is thought to be specific for SFT. With more routine use of fusion gene panels, the histologic diversity of NAB2::STAT6-positive tumors is increasingly appreciated.

Objective: To evaluate the prevalence of nondiabetic renal diseases (NDRDs) in renal biopsies of patients with diabetes mellitus (DM) in the University Hospital of Ribeirão Preto, São Paulo. . We conducted a retrospective study including kidney biopsies performed in diabetic patients between 1987 and 2013.

Angiomatoid fibrous histiocytoma (AFH) is a rarely metastasizing neoplasm that typically occurs in the deep dermis and subcutis of the extremities of young patients, characterized by a t(2;22) translocation involving EWSR1 and CREB1. Because of its distinctive histologic features, the diagnosis of AFH is generally straightforward, although the immunohistochemistry (IHC) findings are relatively nonspecific. We recently encountered a case of primary cranial AFH that showed strong MUC4 IHC expression, which has not yet been reported previously.
