Introduction: Cancer treatment is multidisciplinary in its character and places a heavy burden on the patient. Quality of life is a concept that is closely related to the satisfaction with life. Cancer patients’ satisfaction with life, especially after recovery, is an increasingly examined indicator of treatment quality. Aim of the study: Evaluation of satisfaction with life in patients after radical cancer treatment. Material and methods: The study included 100 people, 81 women and 19 men of all ages, following radical treatment of various cancers. The study was conducted in 2016 at the Centre of Oncology in Bydgoszcz. The study used the Satisfaction with Life Scale (SWLS), adapted by Z. Juczyński, as well as a sociodemographic data questionnaire. Results: In general, cancer patients have an average level of satisfaction with life – the average score was 22.37 and 6.19 sten. The greatest satisfaction with life (average points) was reported for professionally active people – 22.67, patients between 41–50 years old – 23.5, patients with secondary education – 23.4, and patients with at least one child – 22.73, though the differences were not statistically significant. Additionally, patients 3–5 years after treatment declared a higher satisfaction with life – 23.05, as did patients without concomitant diseases – 22.77, though again the results were statistically non-significant. Conclusions: In general, patients after radical anti-cancer treatment have an average satisfaction with life, and in half of them satisfaction with life is high, regardless of the duration and type of cancer. Sociodemographic factors have no impact on the satisfaction with life scores.

Rehabilitation of patients with a diagnosed cancer poses a major challenge for physiotherapists (PT) due to the limited number of methods which may be used on every stage of cancer treatment (including convalescence). Kinesiology Taping (KT) is one of the few available options that enable pain and oedema reduction. Limited number of studies with significantly varied study methods makes it difficult to draw clear conclusions on the legitimacy of KT use. Aim of the review was to analyse available studies on the KT use in pain management and associated discomfort reported by cancer patients. Six papers met the criteria for the review and were included in the detailed pooled analysis (2 clinical studies and 4 case studies). Analysis emphasized papers describing analgesic effect of KT. On the basis of available studies, it proved to be beneficial for oncology patients (breast cancer, lung cancer, multiple myeloma). Additionally, studies reported an increased ability to carry out daily activities, decreased ‘psychological suffering’ and lower fatigue which directly resulted in the improvement of the quality of life (QoL) – a main goal of palliative care. The number of studies that evaluate the effectiveness of KT in pain reduction in oncology patients is scarce. Since KT has minor adverse effects it is recommended to be used as an adjunct analgesic therapy. Review supports the effectiveness of KT for pain management in oncologic patients. In order to confirm the efficacy of KT use in cancer patients, a greater number of randomized clinical trials, covering larger study groups, is required with special emphasis on malignant neoplasms.

Kinins, a group of important pro-inflammatory peptides, are abundantly found in tissues and biological fluids of cancer patients. Bradykinin, the major representative of kinins, induces vascular permeability and, in consequence, promotes tumor expansion. Additionally, the kinin-induced inflammatory responses, especially those mediated by kinin metabolites without the C-terminal arginine residue, lead to enhanced tumor growth. The present study aimed at analyzing the ability of the human glioblastoma cell line U-373, derived from a malignant tumor, to produce kinin peptides. The proteins involved in kinin generation, i.e., the kininogens and the kallikreins, were shown to be expressed in these cells. Moreover, tumor necrosis factor α, a proinflammatory cytokine that mediates tumorigenesis, was found to enhance the expression of enzymes associated with kinin production. The strong binding of kininogen to the cell surface and the enzymatic degradation of this protein by cells suggest the activation of kinin-generating systems. Indeed, glioblastoma cells, pre-treated with tumor necrosis factor α, released kinin peptides from exogenous kininogen. The expression of kinin receptors in these cells was also shown to increase under the influence of this cytokine. Our results suggest that the human glioblastoma cell line U-373 constitutes a good cellular model that can be helpful in cancer research focused on kinin-induced inflammation. Furthermore, our findings can contribute to new approaches in cancer treatment with the use of kinin receptor antagonists and inhibitors of kinin production.

Stimuli-responsive drug delivery system is a concept in which a drug is delivered at a suitable rate in response to stimuli. States of diseases may cause an alteration in some parameters of the body (e.g. in tumors) and the onset and offset of the drug delivery can be done by using this as a stimuli or a "trigger". Stimuli-responsive ("intellectual" or "sharp") resources and molecules show abrupt property changes in response to miniature changes in external stimuli such as pH, temperature etc. For regulated drug delivery, environmental stimuli such as pH and temperature, which undertake phase transition in polymer system, have been investigated. Thermally-responsive polymers can be tuned to a preferred temperature variety by copolymerization with a hydrophilic co-monomer or a hydrophobic co-monomer. Hydrophilic co-monomers increase the LCST while hydrophobic co-monomers decrease the LCST. The stimuli responsive polymer for regulated drug delivery can contain a polymer and copolymers having equilibrium of hydrophilic and hydrophobic groups. A number of these polymers have been investigated extensively and some success in drug delivery with them has been achieved, such as polymers and copolymers of N-isopropylacrylamide, PLGA, and PLA, HEMA etc. Thus this review is designed for stimuli pH and temperature responsive polymeric nanoparticles, which would be helpful to treat various cronic diseases such as cancer and others, for scientists in the field of the regulated drug delivery system.

The main aim of this work is to highlight the problem of the nature and meaning of suffering related to cancer. The purpose of the interviews that we carried out was to learn the patterns of grieving that follows the death of someone close. Study was conducted in the group of 41 people at the time of mourning and bereavement after the loss of the loved ones due to a malignant cancer. Interviews with grieving persons were conducted from December 2008 to January 2010. The obtained results confirm that the problem of suffering related to patients in advanced stages of cancer is multidimensional. This problem needs to be solved by an interdisciplinary hospice palliative care.

We present the case of a 70-year-old male patient with metastatic and castration-resistant prostate cancer as well as advanced bladder cancer, who suffered a non-ST-elevation myocardial infarction (NSTEMI). The cause of ischemia was critical left main stem stenosis, and right coronary artery stenosis. Initially, the patient was qualified for conservative treatment, but due to the intensifying symptoms of myocardial ischemia, it was decided that a hemodynamic intervention was necessary. Two drug-eluting stents were implanted, leading to clinical improvement. Following the treatment, the patient was considered as a candidate for further anti-cancer therapy. Unfortunately, due to the bladder cancer progression, anaemia and haemorrhage, his clinical condition exacerbated, and the patient died about 1 month from the cardiac intervention. Apart from the case description, the paper includes a review of literature on the treatment of acute coronary syndromes without ST-segment elevation in cancer patients.

Numerous studies have shown that consumption of soybean products decrease the risk of cancers in humans. Experiments at the molecular level have demonstrated that in most cases proteins and peptides are responsible for the anticancer properties of soybeen. Special attention should be paid to lunasin - a peptide described for the first time 16 years ago. Due to its structure it causes i.a., inhibition of cancer cell proliferation. A novel procedure for the isolation and purification of low-molecular-mass 2S soybean albumin protein is described in the present paper. A fraction of four peptides one of them corresponding to molecular mass and isoelectric point characteristic for lunasin. The obtained peptides decreased on the rate of HeLa cell proliferation.

Introduction: Beta-glucuronidase (GLU) is a lysosomal exoglycosidase involved in the catabolism of glycoconjugates. Excessive GLU activity may be a primary factor in the etiology of colon cancer. The stimulation of glycosidases and other degradative enzyme activity has been noted in cancers as well as in alcohol and nicotine addiction. Purpose: To compare the serum GLU activity between alcohol- and nicotine-dependent colon cancer patients and colon cancer patients without a history of alcohol- and nicotine-dependence. Materials and methods: Material was the serum of 22 colon cancer patients, 11 of whom met alcohol and nicotine dependence criteria. The activity of serum GLU (pKat/ml) was determined by the colorimetric method. Carcinoembryonic antigen (CEA) concentration (ng/ml) in the serum was determined by the immunoenzymatic method. Comparisons between groups were made using the Mann-Whitney “U” test. Spearman’s rank correlation coefficient was used to measure the association between two variables. Results: The activity of serum GLU was significantly higher in colon cancer patients with a history of alcohol and nicotine dependence, than in the colon cancer patients without a history of drinking and smoking (p=0.003). There was no significant difference in the CEA concentration between colon cancer patients with and without a history of drinking and smoking. Conclusion: Alcohol and nicotine addiction may increase the serum GLU activity in all cancer patients, as already seen in colon cancer patients. This may potentially be important for the degradation of pericancerous matrix, tumor growth, invasion and metastasis

The health transformation that took place after the Second World War in Europe was significantly delayed in the Central and Eastern European countries compared to countries of Northern Europe and United Kingdom. However, as death rates from cardiovascular disease have begun to fall since the 1990s, cancer has emerged as the most common cause of death among young and middle-aged adult women (20-64 years old) in the Central and Eastern European countries. In the coming decade it seems likely to be the leading cause of death among young and middle-aged adult men.The aim of the study was to compare the diversity in cancer risk, contrasting the "old" (EU-15) and the "new" Member States of European Union coming from Central and Eastern European (EU-10) and separately Poland.Material and methods. Data on deaths (1959-2002) in each country have been extracted from the World Health Organization database. Population data are from the Population Division of the Department of Economic and Social Affairs of the United Nations. Direct standardization has been undertaken using the World Standard Population.Results. The difference in life expectancy attributable to cancer for group 20-64 years of age is 0.68 of a year (16% of the total gap) among men and 0.35 of a year (24% of the total) among women. Trends in cancer over time differ significantly by gender, age group and time period in Central and Eastern Europe. The predicted mortality rate in Central and Eastern Europe in 2015 equates to 201/105 (95% CI 198.9-204) for men and 105.6/105 (95% CI 104.1-107.0) for women.Conclusions. In the Central and Eastern European countries deficiency of primary prevention is a main reason of poor health consciousness (consequences of smoking, fatty diet, low physical activity) and late introduction of poorly organized secondary prevention is responsible for worse survival of cancer patients, however tertiary prevention (therapy) is implemented in similar way as in Western Europe. Our analysis indicates that the greatest possibilities, but also the greatest unmet need, lie in primary and secondary prevention.

This article reviews the evidence for the danger model in the context of immune response to tumors and the insufficiency of the immune system to eliminate tumor growth. Despite their potential immunogenicity tumors do not induce significant immune responses which could destroy malignant cells. According to the danger model, the immune surveillance system fails to detect tumor antigens because transformed cells do not send any danger signals which could activate dendritic cells and initiate an immune response. Instead, tumor cells or antigen presenting cells turn off the responding T cells and induce tolerance. The studies reviewed herein based on model tumor antigens, recombinant viral vectors and detection of tumor specific T cells by MHC/peptide tetramers underscore the critical role of tumor antigen presentation and the context in which it occurs. They indicate that antigen presentation only by activated but not by cancer or resting dendritic cells is necessary for the induction of immune responses to tumor antigens. It becomes apparent that the inability of dendritic cells to become activated provides a biological niche for tumor escape from immune destruction and seems to be a principal mechanism for the failure of tumor immune surveillance.

Venous thromboembolism often coexists with cancer, deteriorating patient prognosis. The diagnosis of cancer in patients who suffer from venous thromboembolism may lead to changes in the anticoagulant therapy administered. We present a case report involving a 72-year-old patient with recurrent venous thromboembolism and chronic thromboembolic pulmonary hypertension in whom the diagnosis of colorectal cancer resulted in the need for modification of the anticoagulant therapy. Oral anticoagulant was replaced with low molecular weight heparin and an inferior vena cava filter was implanted due to active bleeding from the anus, high perioperative risk of bleeding, which caused the need for a temporary interruption of anticoagulant therapy.

Tumor endothelial cells are actively involved in the neovascularization processes that accompany tumor growth. Their easy accessibility for systemically applied therapeutics makes them interesting targets for therapeutic intervention. Especially for drug targeting-based therapeutics that often consist of macromolecular moieties, the tumor endothelium is considered a much better target than the tumor cells located behind the vascular wall barrier. In this review, the general principles underlying the development and choices in the development of vascular drug-targeting strategies are discussed. An overview of target epitopes identified in the past two decades is followed by a summary of those strategies that directly or indirectly induced tumor blood flow blockade in vivo. The demonstrated therapeutic success in pre-clinical animal models in debulking large tumor masses and inhibiting tumor outgrowth warrant further development of these therapeutic approaches. Yet, more effort should be put in studies in which the efficacy of different effector activities aimed at the same target, of one effector activity aimed at different targets, and of multiple target strategies are be compared. Combining these data with proper inventories on the molecular basis of tumor endothelial heterogeneity in general will make possible the development of tumor vascular drug-targeting strategies towards clinical application.

Integrative photodynamic therapy (IPDT) of tumors consists of combined use of different curable factors that extremely increase the effectiveness of IPDT. The leading curable effect of PDT is determined by developing of aggressive photochemical reactions in the tumor. The main destructive factor of these reactions is the generation of free radicals that kill tumor’s cells. For PDT efficacy increasing it is necessary to solve the following problems and assure: easiness of production or synthesis; accumulation high selectivity regarding tumor tissue; low toxicity in light and darkness; singled oxygen generation high quant output; promptly elimination from the organism after the treatment procedure; good absorption in spectral intervals most transparent for tissues (red and infrared intervals); optimal interconversion between quant output and fluorescence quant output. PDT effectiveness may be significantly increased by means of: increasing of photosentisizer selectivity and accumulation in tumor tissue; increasing of tumor tissue photochemical destruction caused by photosensitizer. Realization of integrative PDT using Cyber Laser may increase tumor therapy effectiveness to 94–96% and at the same time will establish a new direction in PDT.

Background: Patients with cancer are at risk of malnutrition. The aim of this study is to assess the nutritional status of patients with cancer who are qualified for home enteral nutrition. Secondary aim is to compare the nutritional status of patients with gastric cancer and with esophageal cancer. Material and methods: Retrospective analysis of medical documentation of 84 participants with cancer who were qualified for home enteral nutrition in Nutritional Counselling Center Copernicus in Gdansk in 2009-2015 was performed. Assessment of nutritional status included body mass index, the level of total protein and albumin in blood serum, total lymphocyte count, and Nutritional Risk Score 2002 method. Results: Patients with gastric cancer most often presented albumin deficiency in comparison with patients with esophageal cancer (p=0.02). The low level of total lymphocyte count in 1mm3 of peripheral blood was observed in 47.6% participants. All the patients qualified for home enteral nutrition received at least 3 points in NRS 2002 method and most often 5 points (40.4%). Conclusions: All patients required nutritional treatment. Notwithstanding, the nutritional status of patients varied. Hypoalbuminemia was observed more often in patients with gastric cancer in comparison with patients with esophageal cancer.

Based on NFZ published aggregate data, the public spending on cancer care in Poland was 6.3 billion PLN in 2011 (or approximately 10% of total public health spending). Poland is one of the few large countries in the world that has two centralised and public data sources for cancer, namely the National Cancer Registry (NCR, pol. Krajowy Rejestr Nowotworów – KRN) and activity expenditure database run by the National Health Fund (NFZ, pol. Narodowy Fundusz Zdrowia). We show in our article that having a population-based registry and a complete treatment/clinical care dataset is a necessary condition to have a useful cancer strategy data set that can in turn lead to evidence based health policies in the area of cancer. Lack of audited and publicly available cancer data means that a coherent cancer strategy, assessing service provision and cost effectiveness of treatments and monitoring outcomes is, in our opinion, currently not possible in Poland. We postulate that Poland should create a task force to create cancer data strategy based on NCIN (National Cancer Intelligence Network) in the UK or Cancer Australia.
