Food, Nutrition, Physical Activity, and the Prevention of Cancer : a Global Perspective : 食物、栄養、身体活動とがんの予防 : 世界的展望(後篇)

Glioblastoma (GBM) is the most popular primary central nervous system cancer and has an extremely expansive course. Aggressive tumor growth correlates with short median overall survival (OS) oscillating between 14 and 17 months. The survival rate of patients in a three-year follow up oscillates around 10%. The interaction of the proteins programmed death-1 (PD-1) and programmed cell death ligand (PD-L1) creates an immunoregulatory axis promoting invasion of glioblastoma multiforme cells in the brain tissue. The PD-1 pathway maintains immunological homeostasis and protects against autoimmunity. PD-L1 expression on glioblastoma surface promotes PD-1 receptor activation in microglia, resulting in the negative regulation of T cell responses. Glioblastoma multiforme cells induce PD-L1 secretion by activation of various receptors such as toll like receptor (TLR), epidermal growth factor receptor (EGFR), interferon alpha receptor (IFNAR), interferon-gamma receptor (IFNGR). Binding of the PD-1 ligand to the PD-1 receptor activates the protein tyrosine phosphatase SHP-2, which dephosphorylates Zap 70, and this inhibits T cell proliferation and downregulates lymphocyte cytotoxic activity. Relevant studies demonstrated that the expression of PD-L1 in glioma correlates with WHO grading and could be considered as a tumor biomarker. Studies in preclinical GBM mouse models confirmed the safety and efficiency of monoclonal antibodies targeting the PD-1/PD-L1 axis. Satisfactory results such as significant regression of tumor mass and longer animal survival time were observed. Monoclonal antibodies inhibiting PD-1 and PD-L1 are being tested in clinical trials concerning patients with recurrent glioblastoma multiforme.

PD-L1/PD-1 Axis in Glioblastoma Multiforme.

Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1) are inhibitory checkpoints that are commonly seen on activated T cells and have been offered as promising targets for the treatment of cancers Immune checkpoint inhibitors (ICIs)targeting PD-1, including pembrolizumab and nivolumab, and those targeting its ligand PD-L1, including avelumab, atezolizumab, and durvalumab, and two drugs targeting CTLA-4, including ipilimumab and tremelimumab have been approved for the treatment of several cancers and many others are under investigating in advanced trial phases ICIs increased antitumor T cells’ responses and showed a key role in reducing the acquired immune system tolerance which is overexpressed by cancer and tumor microenvironment However, 50% of patients could not benefit from ICIs monotherapy To overcome this, a combination of ipilimumab and nivolumab is frequently investigated as an approach to improve oncological outcomes Despite promising results for the combination of ipilimumab and nivolumab, safety concerns slowed down the development of such strategies Herein, we review data concerning the clinical activity and the adverse events of ipilimumab and nivolumab combination therapy, assessing ongoing clinical trials to identify clinical outlines that may support combination therapy as an effective treatment To the best of our knowledge, this paper is one of the first studies to evaluate the efficacy and safety of ipilimumab and nivolumab combination therapy in several cancers

Introduction Breast cancer is the most common cancer among women and is the second cancer frequently occurring worldwide of newly-diagnosed cancers. There is much evidence showing the influence of life style and environmental factors on the development of mammary gland cancer (high-fat diet, alcohol consumption, lack of physical exercise), the elimination of which (primary prevention) may contribute to a decrease in morbidity and mortality. Secondary prevention, comprising diagnostic tests (e.g. mammography, ultrasonography, magnetic resonance imaging, breast self-examination, as well as modern and more precise imaging methods) help the early detection of tumours or lesions predisposing to tumours. Objective The aim of this study paper is to review current knowledge and reports regarding primary and secondary prevention of breast cancer. State of knowledge It is estimated that nearly 70% of malign tumours are caused by environmental factors, whereas in breast cancer this percentage reaches 90-95%. There are national programmes established in many countries to fight cancer, where both types of prevention are stressed as serving to decrease morbidity and mortality due to cancers. Conclusions Cancer prevention is currently playing a key role in the fight against the disease. Behaviour modification, as well as greater awareness among women regarding breast cancer, may significantly contribute towards reducing the incidence of this cancer. Another important aspect is the number of women undergoing diagnostic tests, which still remains at an unsatisfactory level.

Primary and secondary prevention of breast cancer

Introduction The overweight and obesity epidemic represents a rapidly growing threat to the health of populations in an increasing number of countries. Nearly one-third of the world's population has excess adipose tissue. Nowadays, obesity occurrence is so common that it is replacing more traditional problems, such as an undernutrition and infectious diseases, as the most significant causes of ill health. If the current trend continues, almost half of the world's adult population will be overweight or obese by 2030. Objective The aim of this study is to show the connection between recent trends in body mass index, and the globally changing cancer profile. State of knowledge A range of clinical and epidemiological studies have shown the relationship between excess body fat and the most frequently occurring malignancies. Obesity is associated with many cancers, such as: breast, colorectal, liver, lung, kidney, oesophageal, pancreatic, endometrium, ovarian, prostate, thyroid, and gallbladder cancer. Conclusions In the light of this information, the study supports the claimed statement that obesity is one of the major health problems of the 21st century. Considering the increase in the number of obese people worldwide, it is necessary to develop a strategy allowing to prevent it. Fighting against unhealthy lifestyle in order to reduce overweight and obesity in society may have an essential impact on decreasing the number of incidences of cancer.

Obesity as a tumour development triggering factor.

Breast cancer is the most common cancer in women. Family history of breast cancer, age at menarche, number of pregnancies and births, history of breast biopsies, use of hormone replacement therapy and time from the last menstrual period are the key events to note. In addition, a high percentage of cases has been demonstrated in women with a genetically conditioned cancer, i.e. mutations in genes BRCA1, BRCA2, syndromes of Li-Fraumeni, Cowden and Peutz-Jeghers. Over 90% of cases are local or regional when detected. The diagnostics approach consists of self-control, breast palpation by the doctor, breast imaging usually with ultrasound, mammography and magnetic resonance. To confirm the diagnosis, a fine-, core-needle or mammotome biopsy is performed. The final diagnosis is based on a wide panel of immunohistochemical and cytogenetic tests. Histological examination provides accurate assessment of the tumor type, grade, estrogen and progesterone hormone receptor status, HER2 overexpression and Ki67 proliferation index. The data makes possible to qualify to one of four groups of breast cancer biological subtypes, which allows individualized treatment of the patient.
