Background: Pregnant and post-partum women with opioid dependence are an extremely vulnerable population within correctional facilities. A significant number of maternal inmates, however, still lack adequate provision of medications for opioid use disorder (OUD) and are subsequently forced into withdrawal. Currently, there exist no comprehensive reviews on the scope of literature regarding the management of this population.

The ongoing challenges posed by COVID-19 are concerning for their impact on successful detection and recognition of melanoma as total body skin examinations and skin biopsies are critical for identifying early-stage melanoma and intervening before progression to metastatic disease. A comprehensive electronic search of PubMed/MEDLINE was conducted on or before August 1, 2022, using the search terms ("skin" AND "COVID-19"), (["skin cancer" AND "COVID-19"] OR ["skin cancer" AND "coronavirus"]), (["melanoma" AND "COVID-19"] OR ["melanoma" AND "coronavirus"]), ("dermatology" AND "COVID-19"), and ("cutaneous" AND "COVID-19"). Eight articles representing Belgium, Chile, France, Germany, Spain, the United Kingdom, and the United States were included.

Background: Antibodies that target a single tumor antigen fail to cure stage IV cancer patients due to tumor heterogeneity and variable expression of antigen. Tumor cells with insufficient binding of antibody will not undergo antibody induced cytotoxicity. We describe targeting multiple tumor-specific antigens that resulted in homogeneous dense binding to mouse melanoma cells and significant tumor growth inhibition.

Background: T cell therapy for cancer involves genetic introduction of a target-binding feature into autologous T cells, ex vivo expansion and single large bolus administration back to the patient. These reprogrammed T cells can be highly effective in killing cells, but tumor heterogeneity results in regrowth of cells that do not sufficiently express the single antigen being targeted. We describe a cell-based therapy that simultaneously targets multiple tumor-specific antigens.

Tumor invasion into draining lymph nodes, especially sentinel lymph nodes (SLNs), is a key determinant of prognosis and treatment in breast cancer as part of the TNM staging system. Using multicolor histology and quantitative image analysis, we quantified immune cells within SLNs from a discovery cohort of 76 breast cancer patients. We found statistically more in situ CD3 T cells in tumor negative vs.

The aim of this preclinical study was to evaluate T7 bacteriophage as a nanoparticle platform for expression of neoantigens that could allow rapid generation of vaccines for potential studies in human cancer patients. We have generated recombinant T7 phage vaccines carrying neoepitopes derived from mutated proteins of B16-F10 melanoma tumor cells. With the single mutated amino acid (AA) centered, peptides were expressed on the outer coat of T7 phage.

Breast cancer metastasizes through the lymphovascular system to the regional lymph nodes in the axilla and to both visceral and non-visceral sites. Renewed interest in the route by which tumor cells gain access to blood and lymphatic capillaries are the subject of research at mechanical, anatomic, pathologic, genetic, epidemiologic and molecular levels. Two papers presented at the 7th International Symposium on Cancer Metastasis in San Francisco showed tumor cells entering the systemic circulation through the sentinel lymph node.

Oct3/4, a transcription factor specifically expressed in mammalian totipotent embryonic stem and germ cells, has a critical role in the regulation and maintenance of pluripotency and self-renewal. However, reactivation of Oct3/4 expression is observed in several human breast cancer cell lines, but not in non‑malignant cells. To examine Oct3/4 expression in human primary breast carcinomas and normal breast tissues, we obtained breast tumor tissues from 28 patients and normal breast tissues from 9 women.

A better understanding of antitumor immune responses is the key to advancing the field of cancer immunotherapy. Endogenous immunity in cancer patients, such as circulating anticancer antibodies or tumor-reactive B cells, has been historically yet incompletely described. Here, we demonstrate that tumor-draining (sentinel) lymph node (SN) is a rich source for tumor-reactive B cells that give rise to systemic IgG anticancer antibodies circulating in the bloodstream of breast cancer patients.

Autoantibodies to breast and other cancers are commonly present in cancer patients. A method to rapidly produce these anti-cancer autoantibodies in the lab would be valuable for understanding immune events and to generate candidate reagents for therapy and diagnostics. The purpose of this report is to evaluate sentinel nodes (SNs) of breast cancer patients as a source of anti-cancer antibodies.

Almost all recent studies confirmed internal mammary sentinel lymph node biopsy (IM-SLNB) as an accurate and valuable technique to determine stage, prognosis, and best treatment option in breast cancer patients. Decision about local treatment of internal mammary lymph nodes (IMLN) is still being made based on Axillary lymph node (ALN) status. According to study results, there will be patients in positive ALN subgroup who just face complications of an unnecessary radiation to IMLNs and there will be patients in negative ALN subgroup who do not receive adjuvant radiation therapy they really need, if we insist to continue planning IMLN treatment based on ALN status.

Background: Dendritic cells (DCs) are important mediators of anti-tumor immune responses. We hypothesized that an in-depth analysis of dendritic cells and their spatial relationships to each other as well as to other immune cells within tumor draining lymph nodes (TDLNs) could provide a better understanding of immune function and dysregulation in cancer.

Methods: We analyzed immune cells within TDLNs from 59 breast cancer patients with at least 5 years of clinical follow-up using immunohistochemical staining with a novel quantitative image analysis system.
