Integrative analysis of H&E and IHC identifies prognostic immune subtypes in HPV related oropharyngeal cancer.

Background: Deep learning techniques excel at identifying tumor-infiltrating lymphocytes (TILs) and immune phenotypes in hematoxylin and eosin (H&E)-stained slides. However, their ability to elucidate detailed functional characteristics of diverse cellular phenotypes within tumor immune microenvironment (TME) is limited. We aimed to enhance our understanding of cellular composition and functional characteristics across TME regions and improve patient stratification by integrating H&E with adjacent immunohistochemistry (IHC) images.

Metformin: A potential adjunct for treatment of systemic mastocytosis.

Background: Systemic mastocytosis (SM) is a clonal disorder of mast cells in which the Asp816Val mutation can be detected not only in mature mast cells but also in the hematopoietic stem cell and in non-mast cell lineages. Current treatment with tyrosine kinase inhibitors provides improved clinical responses in patients with advanced mastocytosis but no cures. Targeting of cancer stem cells (CSCs) resistant to chemotherapy and radiation therapy potentially could improve clinical outcomes in mastocytosis.

Assessing the capacity of methylated DNA markers of cervical squamous cell carcinoma to discriminate oropharyngeal squamous cell carcinoma in human papillomavirus mediated disease.

Objective: Early identification of human papillomavirus associated oropharyngeal squamous cell carcinoma (HPV(+)OPSCC) is challenging and novel biomarkers are needed. We hypothesized that a panel of methylated DNA markers (MDMs) found in HPV(+) cervical squamous cell carcinoma (CSCC) will have similar discrimination in HPV(+)OPSCC tissues.

Materials And Methods: Formalin-fixed, paraffin-embedded tissues were obtained from patients with primary HPV(+)OPSCC or HPV(+)CSCC; control tissues included normal oropharynx palatine tonsil (NOP) and cervix (NCS).

Impact of Tumor-Infiltrating Lymphocytes on Disease Progression in Human Papillomavirus-Related Oropharyngeal Carcinoma.

Objective: We aim to explore the prognostic value of tumor-infiltrating lymphocytes (TILs) in the primary tumor and metastatic lymph nodes of patients with HPV(+)OPSCC. We hypothesize that TILS density at both sites is associated with disease-free survival in HPV(+)OPSCC.

Study Design: Matched case-control study among HPV(+)OPSCC patients who underwent intent-to-cure surgery.

Larynx proteomics after jellyfish collagen IL: Increased ECM/collagen and suppressed inflammation.

Objectives/hypothesis: Compare proteomic profiles of rabbit vocal folds (VFs) injected with micronized cross-linked jellyfish collagen "collagen Type 0" (MX-JC) against two clinical products for injection medialization laryngoplasty (IL).

Study Design: Animal model.

Methods: Left recurrent laryngeal nerve sectioning and IL were performed in New Zealand White rabbits ( = 6/group).
