Brachytherapy for targeting the immune system in cervical cancer patients.

Background: New combinations based on standard therapeutic modalities and immunotherapy require understanding the immunomodulatory properties of traditional treatments. The objective was to evaluate the impact of brachytherapy (BT) on the immune system of cervical cancer and to identify the best modality, High-dose-rate brachytherapy (HDR-BT) vs. Pulsed-dose-rate (PDR-BT), to target it.

Changes in peripheral immune cells after intraoperative radiation therapy in low-risk breast cancer.

A detailed understanding of the interactions and the best dose-fractionation scheme of radiation to maximize antitumor immunity have not been fully established. In this study, the effect on the host immune system of a single dose of 20 Gy through intraoperative radiation therapy (IORT) on the surgical bed in low-risk breast cancer patients undergoing conserving breast cancer has been assessed. Peripheral blood samples from 13 patients were collected preoperatively and at 48 h and 3 and 10 weeks after the administration of radiation.

Immunoradiotherapy as An Effective Therapeutic Strategy in Lung Cancer: From Palliative Care to Curative Intent.

Lung cancer is one of the main causes of cancer-related mortality worldwide. Over the years, different therapeutic modalities have been adopted depending on tumor stage and patient characteristics, such as surgery, radiotherapy (RT), and chemotherapy. Recently, with the development of immune-checkpoint inhibitors (ICI), the treatment of metastatic and locally advanced non-small cell lung cancer (NSCLC) has experienced a revolution that has resulted in a significant improvement in overall survival with an enhanced toxicity profile.

Changes of CD68, CD163, and PD-L1 tumor expression during high-dose-rate and pulsed-dose-rate brachytherapy for cervical cancer.

Purpose: We hypothesized that radiation doses delivered with high-dose-rate (HDR) and pulsed-dose-rate (PDR) brachytherapy in patients with cervical cancer could trigger immune stimulation by modulating immune cells in the tumor microenvironment. The objective was to determine CD68, CD163, and PD-L1 expression in biopsies from patients with cervical cancer and to compare the effects of HDR vs. PDR brachytherapy on the expression of these proteins.

Preliminary Study of the Effect of Stereotactic Body Radiotherapy (SBRT) on the Immune System in Lung Cancer Patients Unfit for Surgery: Immunophenotyping Analysis.

An immunophenotyping analysis was performed in peripheral blood samples from seven patients with lung cancer unfit for surgery treated with stereotactic body radiotherapy (SBRT). The objective was to characterize the effect of SBRT on the host immune system. Four patients received 60 Gy (7.

Enhancing radiotherapy effect in breast cancer with nanoparticles: A review.

Amongst all efforts for improving oncological management outcomes, nanoparticles enhanced radiation for breast cancer patient's treatment is a novel approach that has grown interest for research in the last decade. Multiple preclinical data has been published, from all around the globe; however, clinical evidence is still insufficient for implementing the method in routine practice and in disease specific management. Gold nanoparticles (AuNP), which may be among the most studed materials, account for the majority of available data; however, some new materials have also been used in preclinical settings.

Nanoparticles applied to cancer immunoregulation.

Aim: In recent years, we have seen a considerable increase in the relevance of nanostructures for the safe delivery of therapeutic agents and their capacity as an immunomodulatory tool.

Materials And Methods: Potential clinical applications related to their unique structural properties have been described in the evolving landscape of immunotherapy.

Results: This review briefly summarizes the evidence for the role of nanoparticles in regulating the immune response.

SAPHO syndrome in the differential diagnosis of metastasis.

SAPHO syndrome was proposed in the late 80s in order to group different osteoarticular manifestations with specific radiological findings such as the hyperostosis of the front part of the chest wall. Prevalence, etiology and pathogenesis of the disease are unknown, while diagnosis is made both clinically and by the specific gammagraphic image of «bull horn» in the sternoclavicular joint. The following case of a 64-year-old woman diagnosed with infiltrating ductal carcinoma of the right breast pT1N0Mx is reported.
