However, clinical evidence regarding its efficacy remains limited.

Relationship of Immediate Breast Reconstruction and the Development of Lymphedema in Breast Cancer Patients With Radiation Therapy.

Purpose: Breast cancer-related lymphedema (BCRL) is often challenging to manage, and knowledge of how to prevent it is limited. There are several well-known risk factors, but recent studies have also suggested the potential association of immediate breast reconstruction with lower incidence, albeit with inconclusive results. Thus, we explored the impact of immediate breast reconstruction on lymphedema incidence in patients with breast cancer who underwent a mastectomy and adjuvant radiation therapy (RT).

TIGIT blockade increases efficacy of PD-1 blockade combined with radiation therapy in triple-negative breast cancer model.

Background And Purpose: T-cell immunoreceptor with Ig and ITIM domains (TIGIT) suppresses functions of CD8 T cells, and radiation therapy (RT) induces stimulation of regulatory T cells (Tregs), thereby limiting antitumor efficacy. This study aims to investigate the role of TIGIT in the immunosuppressive tumor environment and evaluate the potential of TIGIT blockade (αTIGIT) to enhance antitumor immune responses.

Methods: We analyzed public transcriptomic data to identify the expression patterns of TIGIT on T cells in breast cancer and its prognostic impact.

The Role of Cacao Powder in Enhancing Skin Moisture and Reducing Wrinkles: A 12-Week Clinical Trial and In Vitro Study.

Skin aging is driven by a combination of internal and external mechanisms, with ultraviolet (UV) radiation being a prominent external factor contributing to photoaging. Photoaging manifests through several signs, including decreased skin hydration, diminished elasticity, coarse wrinkles, and dyspigmentation. Cacao beans, known for their flavonoids and polyphenols, offer potential anti-aging benefits.

Methods And Materials: We tested the "in vitro-irradiated cancer vaccine (ICV)", wherein tumor cells killed by varying doses of irradiation and their supernatants are intravenously injected.

Current status of advance care planning, palliative care consultation, and end-of-life care in patients with glioblastoma in South Korea.

Background: Given the typical trajectory of glioblastoma, many patients lose decision-making capacity over time, which can lead to inadequate advance care planning (ACP) and end-of-life (EOL) care. We aimed to evaluate patients' current ACP and EOL care status.

Patients And Methods: We conducted a cohort study on 205 patients referred to oncologists at a Korean tertiary hospital between 2017 and 2022.

Modulation of CD8 T Cell Responses by Radiotherapy-Current Evidence and Rationale for Combination with Immune Checkpoint Inhibitors.

Radiotherapy for cancer has been known to affect the responses of immune cells, especially those of CD8 T cells that play a pivotal role in anti-tumor immunity. Clinical success of immune checkpoint inhibitors led to an increasing interest in the ability of radiation to modulate CD8 T cell responses. Recent studies that carefully analyzed CD8 T cell responses following radiotherapy suggest the beneficial roles of radiotherapy on anti-tumor immunity.

Combination of local radiotherapy and anti-glucocorticoid-induced tumor necrosis factor receptor (GITR) therapy augments PD-L1 blockade-mediated anti-tumor effects in murine breast cancer model.

Purpose: In this study, we investigated whether local radiotherapy (RT) and an anti-glucocorticoid-induced tumor necrosis factor receptor (GITR) agonist could increase the efficacy of PD-L1 blockade.

Methods And Materials: We analyzed a breast cancer dataset from the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) to determine the role of GITR in breast cancer. We used the 4T1 murine TNBC model (primary and secondary tumors) to investigate the efficacy of PD-L1 blockade, local RT, anti-GITR agonist, and their combinations.
