Impact of Radiation Therapy on Biological Parameters in Cancer Patients: Sub-analysis from the RIT Prospective Epidemiological Study.

Scarce data investigate the impact of radiotherapy (RT) on biology markers. An analysis of ancillary study of RIT (Radiation Impact on Thromboembolic events) prospective trial was carried out. All patients with non-metastatic solid tumors and treated with radiotherapy and/or brachytherapy in curative and consenting to have blood samples were included.

Venous thromboembolism and radiation therapy: The final radiation-induced thrombosis study analysis.

Background: Thromboembolic events frequently complicate the course of malignancy and represent a major cause of morbidity and mortality in cancer patients. In contrast to chemotherapy and other systemic therapies, little is known about the impact of ionizing radiations on the incidence of venous thromboembolism (VTE) in cancer patients.

Methods: In the present prospective study, we aimed to investigate the incidence, management, and outcome of VTE in newly diagnosed cancer patients who received curative radiotherapy.

Assessing toxicities of curative radiotherapy combined with concomitant non anti-cancer drugs: A sub-analysis of the prospective epidemiological RIT trial.

Background And Purpose: Limited data are available about non-anticancer treatment (NACTs)/radiation combinations. MORSE 02-17 was the first study to report on the interaction resulting from such combinations in a heterogeneous population. Therefore, the aim of this study was to describe acute and late toxicities in a homogenous cohort of cancer patients receiving NACTs and undergoing radiation therapy.

Efficacy and tolerance of thoracic radiotherapy in the oldest old patients: A case series.

Background: There are only scarce data on the management of nonagenarians with lung cancer, and more particularly on the place of radiation therapy. The aim of the present study was to retrospectively evaluate the efficacy and tolerance of radiotherapy (RT) in nonagenarians with thoracic cancer.

Patients And Methods: Records from RT departments from four institutions were reviewed to identify patients 90 years old of age and older undergoing RT over the past decade for thoracic cancer and more particularly lung cancer.

Safety assessment of anticancer drugs in association with radiotherapy in metastatic malignant melanoma: a real-life report : Radiation/systemic drug combo in metastatic melanoma.

Purpose: To assess the safety of the association of radiotherapy (RT) and systemic treatments for patients with metastatic malignant melanoma (mMM).

Methods: A retrospective analysis included consecutive patients treated with palliative RT, and at least one line of systemic therapy for mMM between 2001 and 2016. Treatments were defined as sequential or concomitant when RT and the systemic drug were administered, respectively, at more or less than five half-lives from each other.

Nowadays, it is known and recognized that the immune system has a central place in the mechanisms of oncogenesis and the effectiveness of anti-cancer therapies. The demonstration of the immuno-stimulatory ability of radiation therapy opens the field to new applications for this therapy already widely used in oncology area. Indeed, radiotherapy is capable of initiating and / or increasing the immune-mediated anti-tumor response.

RADIORESISTANCE AND BEYOND: Metastatic renal cancer has a poor prognosis because of the limited impact of usual treatment modalities, and notably radiotherapy. Renal cell carcinoma is traditionally considered to be radioresistant, and conventional radiotherapy fraction sizes of 1.8 to 2 Gy are thought to have little role in its management.

Radiotherapy in triple-negative breast cancer: Current situation and upcoming strategies.

Triple-negative breast cancer (TNBC) (estrogen receptor-negative, progesterone receptor-negative, and HER2-negative) is viewed as an aggressive subgroup of breast cancer. Treating patients with TNBC remains clinically challenging. It's now well established than radiation therapy is able to improve locoregional control in breast cancer patients both after breast conserving surgery or mastectomy, with positive impact in high-risk patients for long-term survival.

Outcomes prediction in pre-operative radiotherapy locally advanced rectal cancer: leucocyte assessment as immune biomarker.

Objective: Leukocytes are hypothesized to reflect the inflammatory tumor microenvironment. We aimed to validate their prognostic significance in a large cohort of patients treated with pre-operative radiation for locally advanced rectal cancer (RC).

Results: From 2004 to 2015, 257 RC patients with available biological data underwent a pre-operative radiotherapy, with a median age of 66 years.

Biological aspects of chondrosarcoma: Leaps and hurdles.

Chondrosarcomas are characterized by their chemo- and radioresistance leading to a therapeutic surgical approach which remains the only available treatment with a 10-year survival between 30% and 80% depending on the grade. Non-surgical treatments are under investigation and rely on an accurate biological understanding of drug resistance mechanisms. Novel targeted therapy which represents a new relevant therapeutic approach will open new treatment options by targeting several pathways responsible for processes of proliferation and invasion.

Evaluation of the quality of the reporting of phase II clinical trials in oncology: A systematic review.

Objective: To describe the current state of knowledge concerning the quality of reporting in phase II clinical trials in oncology and to describe the various methods published allowing this quality evaluation.

Methods: databases including MEDLINE and COCHRANE were searched. Reviews and meta-analyses analyzing the quality of the reporting of phase II trials in oncology were included.

A retrospective survey of the last 3 months of life in patients carrying glioblastoma: Clinical treatments and profiles.

Glioblastoma is one of the most common types of primary brain tumor. In situations of local recurrence, physicians can suggest either specific palliative anticancer treatments (SPAT; surgery, chemotherapy, radiotherapy) or best supportive care (BSC). The objective of the present study was to identify clinical factors that may have influenced the continuation or cessation of SPAT during the final 3 months of life in patients with glioblastoma.

Evaluation of the Cell Invasion and Migration Process: A Comparison of the Video Microscope-based Scratch Wound Assay and the Boyden Chamber Assay.

The invasion and migration abilities of tumor cells are main contributors to cancer progression and recurrence. Many studies have explored the migration and invasion abilities to understand how cancer cells disseminate, with the aim of developing new treatment strategies. Analysis of the cellular and molecular basis of these abilities has led to the characterization of cell mobility and the physicochemical properties of the cytoskeleton and cellular microenvironment.

Quality of reporting in oncology phase II trials: A 5-year assessment through systematic review.

Background: Phase II clinical trials are a cornerstone of the development in experimental treatments They work as a "filter" for phase III trials confirmation. Surprisingly the attrition ratio in Phase III trials in oncology is significantly higher than in any other medical specialty. This suggests phase II trials in oncology fail to achieve their goal.

[Impairment of DNA damage response and cancer].

Maintaining the genetic integrity is a key process in cell viability and is enabled by a wide network of repair pathways. When this system is defective, it generates genomic instability and results in an accumulation of chromosomal aberrations and mutations that may be responsible for various clinical phenotypes, including susceptibility to develop cancer. Indeed, these defects can promote not only the initiation of cancer, but also allow the tumor cells to rapidly acquire mutations during their evolution.

[Biomarkers of radiation-induced DNA repair processes].

The identification of DNA repair biomarkers is of paramount importance. Indeed, it is the first step in the process of modulating radiosensitivity and radioresistance. Unlike tools of detection and measurement of DNA damage, DNA repair biomarkers highlight the variations of DNA damage responses, depending on the dose and the dose rate.

Healing touch in radiation therapy: is the benefit tangible?

Background: Cancer patients tend to use more and more complementary or alternative medicine concomitantly to radiotherapy. A large part of these patients have recourse to Mind and Body practice, mainly with biofield healers or magnetizers, without any level of evidence. The aim of the present study was to report epidemiologic data on biofield healers in radiation therapy patients, and to assess the possible objective and subjective benefits.

Dual "mAb" HER family blockade in head and neck cancer human cell lines combined with photon therapy.

Head and neck cancer stem cells (CSCs) are highly resistant to treatment. When EGFR is overexpressed in head and neck squamous cell carcinoma (HNSCC), HER2 and HER3 are also expressed. The aim of the present study was to investigate the effect of HER1/2/3 blockade through a combination of cetuximab and pertuzumab, with or without photon irradiation, on the proliferation and migration/invasion capabilities of an HNSCC chemo- and radioresistant human cell line (SQ20B) and its corresponding stem cell subpopulation.
