Furthermore, we observed even greater activation and type 1 polarization in tissue-infiltrating T cells, described here for the first time in a series of patients with HLH. Finally, we observed that a threshold of >7% CD38high/HLA-DR+ cells among CD8+ T cells had strong positive and negative predictive value for distinguishing HLH from early sepsis or healthy controls. We conclude that the cytokine storm of HLH is marked by distinctive T-cell activation whereas early sepsis is not, and that these 2 syndromes can be readily distinguished by T-cell phenotypes.Polycythemia and pulmonary hypertension are 2 human diseases for which better therapies are needed. Upregulation of hypoxia-inducible factor-2α (HIF-2α) and its target genes, erythropoietin (EPO) and endothelin-1, causes polycythemia and pulmonary hypertension in patients with Chuvash polycythemia who are homozygous for the R200W mutation in the von Hippel Lindau (VHL) gene and in a murine mouse model of Chuvash polycythemia that bears the same homozygous VhlR200W mutation. Moreover, the aged VhlR200W mice developed pulmonary fibrosis, most likely due to the increased expression of Cxcl-12, another Hif-2α target. Patients with mutations in iron regulatory protein 1 (IRP1) also develop polycythemia, and Irp1-knockout (Irp1-KO) mice exhibit polycythemia, pulmonary hypertension, and cardiac fibrosis attributable to translational derepression of Hif-2α, and the resultant high expression of the Hif-2α targets EPO, endothelin-1, and Cxcl-12. In this study, we inactivated Hif-2α with the second-generation allosteric HIF-2α inhibitor MK-6482 in VhlR200W, Irp1-KO, and double-mutant VhlR200W;Irp1-KO mice. MK-6482 treatment decreased EPO production and reversed polycythemia in all 3 mouse models. Drug treatment also decreased right ventricular pressure and mitigated pulmonary hypertension in VhlR200W, Irp1-KO, and VhlR200W;Irp1-KO mice to near normal wild-type levels and normalized the movement of the cardiac interventricular septum in VhlR200Wmice. MK-6482 treatment reduced the increased expression of Cxcl-12, which, in association with CXCR4, mediates fibrocyte influx into the lungs, potentially causing pulmonary fibrosis. Our results suggest that oral intake of MK-6482 could represent a new approach to treatment of patients with polycythemia, pulmonary hypertension, pulmonary fibrosis, and complications caused by elevated expression of HIF-2α.NOTCH1 gain-of-function mutations are recurrent in B-cell chronic lymphocytic leukemia (B-CLL), where they are associated with accelerated disease progression and refractoriness to chemotherapy. The specific role of NOTCH1 in the development and progression of this malignancy is unclear. Here, we assess the impact of loss of Notch signaling and pathway hyperactivation in an in vivo mouse model of CLL (IgH.TEμ) that faithfully replicates many features of the human pathology. PX478 Ablation of canonical Notch signaling using conditional gene inactivation of RBP-J in immature hematopoietic or B-cell progenitors delayed CLL induction and reduced incidence of mice developing disease. In contrast, forced expression of a dominant active form of Notch resulted in more animals developing CLL with early disease onset. Comparative analysis of gene expression and epigenetic features of Notch gain-of-function and control CLL cells revealed direct and indirect regulation of cell cycle-associated genes, which led to increased proliferation of Notch gain-of-function CLL cells in vivo. These results demonstrate that Notch signaling facilitates disease initiation and promotes CLL cell proliferation and disease progression.
Translocation-associated renal cell carcinoma involving ALK (ALK-tRCC) is a rare subtype of adult renal cell carcinoma (RCC) reported in recent years.

A new Italian case of ALK-tRCC was reported. The patient was a female 44-year-old with a metastatic and pretreated RCC. The tumor showed a rearrangement of ALK gene in tumor cells detected by targeted next-generation sequencing panel. The patient received oral alectinib therapy and achieved a partial response.

ALK-tRCC is a rare subtype of adult RCC. Its diagnosis is very difficult because the genomic alteration spectrum is very wide. We suggested that metastatic RCCs should be screened for uncommon genomic alterations expecially in good performance status pretreated resistant/refractory patients.

In some cases, these alterations have been recognized as having a pathogenic role and targeted therapies capable of inhibiting tumor proliferation by selective and specific blocking of the enzymatic activity of the related abnormal proteins have been developed. This has made it possible to improve the effectiveness of the treatments by minimizing toxicity. Today it is essential to apply Comprehensive Genomic Profiling methods also in clinical practice, in order to allow the best treatment available for each patient, possibly also in the context of clinical trials. Below we report the clinical history of a patient with advanced stage adenocarcinoma of the lung with molecular diagnosis of RET fusion, treated with pralsetinib with excellent clinical and radiological response and good tolerability. This clinical case emphasizes the importance of the broader molecular profiling in patients with advanced NSCLC (especially for non-squamous histology) from the diagnosis before starting first-line treatment.Advances in cancer biology research led to the identification of new molecular drivers in non-small cell lung cancer. These alterations should be searched especially in young and never-smoker patients, in order to ensure access to targeted therapies. In particular, RET mutations occur in 1-2% of lung adenocarcinomas and represent the molecular target of innovative treatments such as pralsetinib. The Next Generation Sequencing provides a comprehensive genomic profiling both on tissue and blood sampling. The liquid biopsy could be extremely advantageous, as it is a simple, non-invasive and repeatable test. We report the case of a non-smoker woman with metastatic lung adenocarcinoma unresponsive to chemotherapy and immunotherapy. RET mutation (RET-KIF5B fusion) was found by liquid biopsy. The patient started therapy with pralsetinib obtaining an early radiological response and a significant clinical benefit.The discovery of gene driver mutations and the increase of next-generation sequencing techniques have radically changed the natural history of NSCLCs. Neuroendocrine lung cancers are a heterogeneous entity whose biology is little known. Sporadic actionable mutations are also reported in this subtype of neoplasms, especially in tumors derived from a transformation of adenocarcinomas. ROS-1 gene rearrangements are found in about 1-2% of lung neoplasms and are characterized by a high sensitivity to specific tyrosine kinase inhibitors (TKis). Here we report the case of a large cell neuroendocrine carcinoma precisely framed and treated thanks to a next-generation genomic approach.
Into blood relatives of patients affected by breast cancer, the prevalence of pancreatic ductal adenocarcinoma (PDAC) seems to be elevated. BRCA1/2 mutations as other VUS (variants of uncertain significance) could be responsible.

We retrospectively revised dataset of Pancreatic Surgery Unit of Humanitas Clinical and Research Center - IRCCS and identified patients who underwent resection for PDAC between 2010 and 2018. We evaluated neoplastic family history and remote pathological history, particularly for breast and prostate tumors. The characteristics of family history were described. Overall survival (OS) and progression free survival (PFS) were calculated for different identified groups.

483 PDAC have been analyzed; 57% had a family history positive for neoplasia; 25% at least showed a blood relative affected by one of these type of cancers PDAC, breast and prostate, of which 88% was a first degree relative (FDR). One hundred and six patients (22%) had a previous neoplasia, of which 8% a breast cancer and 4% a prostate one. Into this group of patients, 54% had a family history positive for neoplasia and 23% consisted of either a pancreatic neoplasm, or breast tumor or prostate cancer; 71% was a FDR. With a median follow-up of 54.9 months (range 0.066-120), the median survival was 22,8 months. Both OS than PFS weren't statistically significant, considering family history and remote pathological history.

There appears to be a high prevalence of breast and prostate cancer in family members and patients with PDAC. PDAC patients have the prognosis of the pancreatic cancer, not influenced by a previous treated neoplasia.

The most commonly used technique is radiofrequency ablation (RFA). Currently, three needle-electrodes and one "through-the-needle" probe are available. Published studies mainly demonstrated the feasibility and safety of the procedure. However, the role of EUS-RFA for the treatment of pancreatic ductal adenocarcinoma is not yet well defined. Randomized studies are needed to assess any advantage in terms of survival and quality of life when RFA is included in a multimodal treatment strategy compared with chemo(radio)therapy alone. In the setting of pancreatic neuroendocrine tumors (pNETs), published studies are consistent in demonstrating the efficacy of EUS-RFA in relieving symptoms related to hormone secretion by functioning pNETs. Moreover, EUS-RFA could find a role even in selected patients with small non-functioning pNETs when treatment is indicated but surgical resection would like to be avoided. Finally, EUS-RFA can be applied also for the treatment of pancreatic cystic neoplasm. However, patients should be carefully selected taking into account the low incidence of progression of cystic neoplasms towards malignancy and factors related to the patient, such as age, symptoms, comorbidity, and life expectancy.Pancreatic ductal adenocarcinoma (PDAC) is a malignant neoplasia with an incidence and a prevalence that are progressively growing. It is estimated that in 2030 it will be the third most common tumor, after lungs and liver. This is due at first because of a delay in the development of new therapies able to change PDAC patients' prognosis and also because at diagnosis the tumor is already in advanced stages. During last years, endoscopic ultrasound (EUS), thanks to its versatility, became the first-choice technique in pancreatic diseases. EUS can be used, in example, in the screening of high-risk subjects (HRI) for the development of PDAC. The screening program is reserved to subjects with germinal mutation in high risk genes and subjects with a familial pancreatic cancer history. EUS was found to be a technique highly sensitive with a slightly good specificity in the detection of pancreatic lesions in HRIs; its diagnostic accuracy is superior to MRI and CT-scan, most of all for small size lesions (respectively 93%, 67% and 53%).
