Increased PD-1 Level in Severe Cervical Injury Is Associated With the Rare Programmed Cell Death 1 () rs36084323 A Allele in a Dominant Model.

Front Cell Infect Microbiol 2021 1;11:587932. Epub 2021 Jul 1.

Laboratory of Immunogenetics, Department of Immunology, Aggeu Magalhães Institute, Oswaldo Cruz Foundation, Recife, Brazil.

The high-risk oncogenic human papillomavirus (HPV) has developed mechanisms for evasion of the immune system, favoring the persistence of the infection. The chronic inflammation further contributes to the progression of tissue injury to cervical cancer. The programmed cell death protein (PD-1) after contacting with its ligands (PD-L1 and PD-L2) exerts an inhibitory effect on the cellular immune response, maintaining the balance between activation, tolerance, and immune cell-dependent lesion.

Infection and food combine to cause atherosclerotic coronary heart disease - Review and hypothesis.

Int J Cardiol Heart Vasc 2021 Aug 6;35:100807. Epub 2021 Jul 6.

School of Biotechnology and Biomolecular Science, University of New South Wales, Sydney, NSW 2052, Australia.

Hypothesis: It is hypothesised that a combination of childhood and later life infections and excess food consumption, particularly of Western style food, initiates and contributes to atherosclerotic coronary heart disease. To consider this hypothesis we have conducted a brief review of the role of childhood infections, food, and their combined influence on atherosclerosis.

Evidence: (i) Studies of populations with high prevalence of infections and low "hunter gather" like food consumption, have extremely low prevalence of atherosclerosis, (ii) there are consistent associations between infections in childhood and adult atherosclerotic coronary heart disease, (iii) there is an association between increased body weight, (an indication of excess eating), and atherosclerotic heart disease, and (iv) there is evidence that a combination of increased body weight and infections influences the development of atherosclerotic coronary heart disease.

The Biological Basis for Enhanced Effects of Proton Radiation Therapy Relative to Photon Radiation Therapy for Head and Neck Squamous Cell Carcinoma.

Int J Part Ther 2021 25;8(1):3-13. Epub 2021 Jun 25.

Department of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Head and neck squamous cell carcinomas (HNSCCs) often present as local-regionally advanced disease at diagnosis, for which a current standard of care is x-ray-based radiation therapy, with or without chemotherapy. This approach provides effective local regional tumor control, but at the cost of acute and late toxicity that can worsen quality of life and contribute to mortality. For patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (SCC) in particular, for whom the prognosis is generally favorable, de-escalation of the radiation dose to surrounding normal tissues without diminishing the radiation dose to tumors is desired to mitigate radiation-related toxic effects.

Changes in Stem Cell Regulation and Epithelial Organisation during Carcinogenesis and Disease Progression in Gynaecological Malignancies.

Cancers (Basel) 2021 Jul 3;13(13). Epub 2021 Jul 3.

Department of Obstetrics and Gynaecology, University Hospital, LMU Munich, Marchioninistr 15, 81377 Munich, Germany.

Gynaecological malignancies represent a heterogeneous group of neoplasms with vastly different aetiology, risk factors, molecular drivers, and disease outcomes. From HPV-driven cervical cancer where early screening and molecular diagnostics efficiently reduced the number of advanced-stage diagnosis, prevalent and relatively well-treated endometrial cancers, to highly aggressive and mostly lethal high-grade serous ovarian cancer, malignancies of the female genital tract have unique presentations and distinct cell biology features. Recent discoveries of stem cell regulatory mechanisms, development of organoid cultures, and NGS analysis have provided valuable insights into the basic biology of these cancers that could help advance new-targeted therapeutic approaches.

Int J Gynecol Pathol 2021 Jul 19. Epub 2021 Jul 19.

Departments of Pathology (O.A., S.Y.Z., F.H., A.A.R., O.F.) Obstetrics and Gynecology, University of California, San Diego, San Diego, California (P.B.).

There have been previous reports of neoplasms with the morphology of endocervical adenocarcinoma in situ (AIS) that secondarily involve the ovaries, presumably through transtubal spread, with a smaller subset metastasizing to distant sites. These ovarian metastases have been discovered up to 7 yr postexcision of the endocervical lesion, consistent with the known potential for overtly invasive cervical carcinomas to recur late after primary curative management. Herein, we present a case of a premenopausal woman with a pelvic mass classified as metastatic human papillomavirus (HPV)-associated endocervical adenocarcinoma (p16-block immunoreactive, high-risk HPV positive by in situ hybridization with PTEN loss, ARID1A, and PBRM1 mutations detected by qualitative next-generation sequencing), identified 17.
