Fasting-Mimicking Diet Is Safe and Reshapes Metabolism and Antitumor Immunity in Patients with Cancer.

2021

Abstract In tumor-bearing mice, cyclic fasting or fasting-mimicking diets (FMD) enhance the activity of antineoplastic treatments by modulating systemic metabolism and boosting antitumor immunity. Here we conducted a clinical trial to investigate the safety and biological effects of cyclic, five-day FMD in combination with standard antitumor therapies. In 101 patients, the FMD was safe, feasible, and resulted in a consistent decrease of blood glucose and growth factor concentration, thus recapitulating metabolic changes that mediate fasting/FMD anticancer effects in preclinical experiments. Integrated transcriptomic and deep-phenotyping analyses revealed that FMD profoundly reshapes antican…

Mortality from cancer and other causes in commercial airline crews: a joint analysis of cohorts from 10 countries.

2014

Background Commercial airline crew is one of the occupational groups with the highest exposures to ionising radiation. Crew members are also exposed to other physical risk factors and subject to potential disruption of circadian rhythms. Methods This study analyses mortality in a pooled cohort of 93 771 crew members from 10 countries. The cohort was followed for a mean of 21.7 years (2.0 million person-years), during which 5508 deaths occurred. Results The overall mortality was strongly reduced in male cockpit (SMR 0.56) and female cabin crews (SMR 0.73). The mortality from radiation-related cancers was also reduced in male cockpit crew (SMR 0.73), but not in female or male cabin crews (SMR…

PINK1 displays tissue-specific subcellular location and regulates apoptosis and cell growth in breast cancer cells.

2010

The PINK1 gene is mutated in the germ line of patients with hereditary early-onset Parkinson disease, and PINK1 prosurvival function at neuronal mitochondria has been related with the etiology of this disease. However, the expression and function of PINK1 protein in nonneuronal tissues has not been determined yet. Here, we have analyzed PINK1 protein expression and subcellular distribution in normal and neoplastic human tissues and investigated the function of PINK1 in breast carcinoma cells. PINK1 protein, as stained by a specific anti-PINK1 monoclonal antibody, was widely expressed in human tissues, displaying high expression in epithelial tissues and in the central nervous system and low…

Design of a randomized controlled trial of physical training and cancer ( Phys-Can) the impact of exercise intensity on cancer related fatigue, quali…

2017

Background: Cancer-related fatigue is a common problem in persons with cancer, influencing health-related quality of life and causing a considerable challenge to society. Current evidence supports the beneficial effects of physical exercise in reducing fatigue, but the results across studies are not consistent, especially in terms of exercise intensity. It is also unclear whether use of behaviour change techniques can further increase exercise adherence and maintain physical activity behaviour. This study will investigate whether exercise intensity affects fatigue and health related quality of life in persons undergoing adjuvant cancer treatment. In addition, to examine effects of exercise …

Pulmonary Laser Metastasectomy by 1318-nm Neodymium-Doped Yttrium-Aluminum Garnet Laser: A Retrospective Study About Laser Metastasectomy of the Lung

2018

Background. The lungs are among the first organ affected by remote metastases from many primary tumors. The surgical resection of isolated pulmonary metastases represents an important and effective element of therapy. This is a retrospective study about our entire experience with pulmonary resection for metastatic cancer using 1318-nm neodymium-doped yttrium-aluminum garnet laser. Method. In this single-institution study, we retrospectively analyzed a group of 209 patients previously treated for primary malignant solid tumors. We excluded 103 patients. The number and location of lesions in the lungs was determined using chest computed tomography and positron emission tomography-computed tom…

Blood Glutathione as an Index of Radiation-Induced Oxidative Stress in Mice and Humans

1997

Abstract The effect of x-rays on GSH and GSSG levels in blood was studied in mice and humans. An HPLC method that we recently developed was applied to accurately determine GSSG levels in blood. The glutathione redox status (GSH/GSSG) decreases after irradiation. This effect is mainly due to an increase in GSSG levels. Mice received single fraction radiotherapy, at total doses of 1.0 to 7.0 Gy. Changes in GSSG in mouse blood can be detected 10 min after irradiation and last for 6 h within a range of 2.0–7.0 Gy. The highest levels of GSSG (20.1 ± 2.9 μ M), a 4.7-fold increase as compared with controls) in mouse blood are found 2 h after radiation exposure (5 Gy). Breast and lung cancer patien…

Prevalence of patients hospitalised for male breast cancer in France using the French nationwide hospital administrative database

2019

BACKGROUND Breast cancer (BC) in men is a rare and neglected disease representing <1% of all cancers in men and only 1% of all incident BC in western countries. OBJECTIVE This study aimed to describe trends in the prevalence of patients hospitalised for male BC in France from 2009 to 2013, using the national administrative database (PMSI). METHODS We included all men aged ≥18 admitted to hospital for BC during this period and estimated the prevalence of male breast cancer hospitalised in France over 5 years. We also describe clinical characteristics and treatments in men with surgery for BC over the 5-year period of the study. RESULTS The prevalence of patients hospitalised for BC significa…

Delay in the Diagnosis of Breast and Colorectal Cancer in People With Severe Mental Disorders

2020

Background People with severe mental disorders have a worse cancer prognosis, with higher mortality rates than the general population, and this could be partially attributed to a later detection. Breast cancer and colorectal cancer have mass population screenings in Spain, but the influence in early diagnosis is unknown in persons with severe mental disorders. Objective To compare the severity of breast and colorectal cancers at diagnosis in people with and without mental disorders. Methods This was an observational, retrospective, case-control study with 1:2 matching performed in Eastern Spain. Data were retrieved for analysis from electronic medical records. Results The study included 111…

Low Protein Intake Is Associated with a Major Reduction in IGF-1, Cancer, and Overall Mortality in the 65 and Younger but Not Older Population

2014

SummaryMice and humans with growth hormone receptor/IGF-1 deficiencies display major reductions in age-related diseases. Because protein restriction reduces GHR-IGF-1 activity, we examined links between protein intake and mortality. Respondents aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a 4-fold increase in cancer death risk during the following 18 years. These associations were either abolished or attenuated if the proteins were plant derived. Conversely, high protein intake was associated with reduced cancer and overall mortality in respondents over 65, but a 5-fold increase in diabetes mortality across all ages. Mouse studies confirmed the effect…
