Head and neck (HnN) cancers are among the most common cancers in the world. Proton therapy (PT) is one of the latest advancements in the treatment modalities of cancers. Proton therapy is specifically used to treat HnN cancer patients due to its less toxic effects on the surrounding critical structures. Keeping in view the opportunities for further advancements, there is a lot of literature covering PT in HnN cancer patients. However, few compiled studies are not enough to compare the toxicities, overall survival (OS), local control (LC), and quality of life (QoL) of PT with that of intensity-modulated radiation therapy (IMRT). The objective of this review is to compile and summarize the literature available on the toxicities, OS, LC, and QoL in HnN cancer patients post PT. We have gathered and summarized the literature found under the keyword "proton therapy for head and neck cancers". Proton therapy is a preferable option over IMRT because it isolates tumors of the HnN, reduces exposure of healthy cells to radiation, and allows accurate tumor scanning using the pencil beam technique. In view of this article, we can say that PT is a preferable mode of radiotherapy for HnN cancer patients in view of its accuracy and lower incidents of acute and late toxicities.

Acute myeloid leukemia (AML) that is relapsed and/or refractory post-allogeneic hematopoietic cell transplantation (HCT) is usually fatal. In a prior study, we demonstrated that AML relapse in high-risk patients was prevented by post-HCT immunotherapy with Epstein-Barr virus (EBV)-specific donor CD8 T cells engineered to express a high-affinity Wilms Tumor Antigen 1 (WT1)-specific T-cell receptor (T). However, in the present study, infusion of EBV- or Cytomegalovirus (CMV)-specific T did not clearly improve outcomes in fifteen patients with active disease post-HCT.

However, most MCED tests rely on a single type of biomarkers, leading to limited sensitivity, particularly for early-stage cancers. We previously developed SPOT-MAS, a multimodal ctDNA-based assay analyzing methylation and fragmentomic profiles to detect five common cancers.

Liver masses in children with underlying systemic disease or a predisposing syndrome can be benign or malignant, ranging from focal fat to hepatocellular carcinoma (HCC). Knowledge of the underlying condition, the pathophysiologic effect on the liver, and the development of liver disease and specific liver lesions allows radiologists to guide imaging with regard to modality and frequency and give recommendations for biopsy when appropriate. In some predisposition disorders, such as Beckwith Wiedemann spectrum, familial adenomatous polyposis syndrome, and tuberous sclerosis complex, established guidelines for imaging screening exist.

Background/objectives: Tumor microenvironmental hypoxia is an established hallmark of solid tumors. It significantly contributes to tumor aggressiveness and therapy resistance and has been reported to affect the balance of activating/inhibitory surface receptors' expression and activity on NK cells. In the current study, we investigated the impact of hypoxia on the surface expression of Siglec-7 and Siglec-9 (Sig-7/9) and their ligands in NK cells and tumor target cells.
