Patient Experience in Neoplastic Disease in Light of the Statements of Doctors Who Are Oncological Patients.

This study aimed to explore oncological doctor-patients experiences concerning the neoplastic disease. The study involved 20 Polish doctors with cancer. Respondents answered open questions related to cancer management and opinions about themselves as oncological patients. The results of the study indicate that doctor-patients deny their susceptibility to illness, which leads to prophylaxis ignorance. Many doctors diagnosed themselves with the disease, but they needed a clear verbal confirmation of the diagnosis by another physician. Respondents well assessed professional skills of doctor-colleagues. However, communication competencies of their doctors were assessed critically. Medical narratives may become an incentive to deepen the discourse on the quality of the relationship between a doctor and a doctor-oncological patient. They may also lead to further research on the anthropological, psychological, and sociological understanding of disease.

Adult Langerhans cell histiocytosis with multi­system bone, skin, lung and liver involvement: A case report.

Langerhans cell histiocytosis (LCH) is a rare neoplastic disorder marked by the uncontrolled proliferation and accumulation of immature myeloid dendritic cells, which originate from the bone marrow. Although LCH can involve various organs, including bone, lymph nodes and skin, multi-system bone, liver and lung involvement with LCH is rare in adults. A case of a 49-year-old man diagnosed with multi-system, aggressive LCH involving bone, skin, lung and liver is presented in the present study. The initial radio-clinic presentation of the patient was initially suggestive of a bone tumor. The current case report aims to draw attention to this rare disease and discuss the diagnostic approach and therapeutic management, which should be noted to help physicians more rapidly identify, diagnose and treat comparable cases.

The Broad Spectrum of Gallbladder Paraneoplastic Syndromes.

Gallbladder carcinoma (GBC) is a rare gastrointestinal tumor with a reported incidence of 1 in 100,000 in the United States. GBC may present with subtle signs and symptoms that can be missed on routine examination and/or confused with other conditions. Unfortunately, its subtle presentation frequently leads to late diagnosis and, thus, a poor prognosis. Several paraneoplastic syndromes have been associated with GBC. Despite their strong associations with neoplastic disease, the precise pathophysiologic mechanisms underlying the development of these syndromes remain poorly understood. Given the vague nature of their initial signs and symptoms, these syndromes are frequently diagnosed as independent entities and only later associated with occult malignancies that may have already metastasized to other organs. Physicians need to be aware of the signs and symptoms of these paraneoplastic syndromes and include an underlying malignancy as part of the differential diagnosis. This review provides a detailed discussion of the paraneoplastic syndromes associated with GBC.

Insights into the Role of Glutathione Peroxidase 3 in Non-Neoplastic Diseases.

Reactive oxygen species (ROSs) are byproducts of normal cellular metabolism and play pivotal roles in various physiological processes. Disruptions in the balance between ROS levels and the body's antioxidant defenses can lead to the development of numerous diseases. Glutathione peroxidase 3 (GPX3), a key component of the body's antioxidant system, is an oxidoreductase enzyme. GPX3 mitigates oxidative damage by catalyzing the conversion of hydrogen peroxide into water. Beyond its antioxidant function, GPX3 is vital in regulating metabolism, modulating cell growth, inducing apoptosis and facilitating signal transduction. It also serves as a significant tumor suppressor in various cancers. Recent studies have revealed aberrant expression of GPX3 in several non-neoplastic diseases, associating it with multiple pathological processes. This review synthesizes the current understanding of GPX3 expression and regulation, highlighting its extensive roles in noncancerous diseases. Additionally, this paper evaluates the potential of GPX3 as a diagnostic biomarker and explores emerging therapeutic strategies targeting this enzyme, offering potential avenues for future clinical treatment of non-neoplastic conditions.

Urolithin A as a Potential Agent for Prevention of Age-Related Disease: A Scoping Review.

The aging of an organism is hallmarked by systemic loss of functional tissue, resulting in increased fragility and eventual development of age-related neurodegenerative, musculoskeletal, cardiovascular, and neoplastic diseases. Growing scientific evidence points to mitochondrial dysfunction as a key contributor in the aging process and subsequent development of age-related pathologies. Under normal physiologic conditions, the body removes dysfunctional mitochondria via an autophagic process known as mitophagy. Urolithin A (UA), a metabolite produced when gut microflora digests the polyphenol compounds ellagitannin and ellagic acid, is a known inducer of mitophagy via several identified mechanisms of action. The primary objective of this scoping review is to identify and summarize the clinical relevance of UA supplementation in the prevention of age-related pathology and diseases. A computer-assisted literature review was performed using PubMed and EMBASE for primary source research articles examining UA supplementation and aging-related pathologies. A total of 293 articles were initially identified from a database search, and 15 articles remained for inclusion in this review, based on predetermined criteria. Analysis of the 15 identified publications demonstrated that UA holds potential as a dietary intervention for slowing the progression of aging and preventing the development of age-related disease. This review also illustrates the potential role that mitochondrial health and inflammation play in the progression of age-related pathology. Identifying the clinical relevance of UA supplementation in the prevention of age-related pathology and diseases will help further the focus of research on treatments that may improve the longevity and quality of life in patients at risk for these comorbidities.

Neoplasia in captive Tsushima leopard cats (Prionailurus bengalensis euptilurus).

The Tsushima leopard cat (Prionailurus bengalensis euptilurus) is a subspecies of the mainland leopard cat that lives on the small island of Tsushima, Japan. Captive breeding has been attempted in zoos in Japan because only approximately 100 animals remain in the wild and the Tsushima leopard cat is an endangered species. There are very few reports on diseases, including tumours, of this species. We analysed the deaths of 58 Tsushima leopard cats and confirmed that nine had neoplastic disease. The average age at death of the animals with neoplasia was 14 years and tumours were the primary cause of death in all animals. Eight of the nine cases involved primary tumours of the pancreas, liver, gallbladder, tongue and salivary glands, suggesting that Tsushima leopard cats may have a predilection for digestive system tumours. This is the first report of neoplastic disease in the Tsushima leopard cat.

Inflammatory Arthritis in a 19-month-old with Von Hippel-Lindau Disease.

Von Hippel-Lindau disease (VHL) is a rare autosomal dominant disease characterized by progressive development of cysts and tumors. Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disorder and the most common arthritis in children. Although the mechanism of pathogenesis is not fully understood, JIA is thought to be a polygenic, autoimmune-mediated disease. Inherited or acquired disorders resulting in immune dysregulation can lead to neoplastic and autoimmune disease, but very few cases of patients with VHL and concomitant autoimmune disease are reported in the literature. Herein, we describe, to the best of our knowledge, the first reported case of a child with VHL and inflammatory arthritis, and we discuss three possible pathophysiologic mechanisms that could link VHL and JIA. Understanding the shared pathophysiology and genetics of both diseases may help guide future direction of targeted therapies and lead to improved clinical outcomes.

Langerhans Cell Histiocytosis Presenting With Clinical Features of Hidradenitis Suppurativa.

Langerhans cell histiocytosis (LCH) is a rare neoplastic disease of myeloid dendritic cells with a widely variable presentation of organ system involvement and severity. In this case report, we share the details of a rare case of cutaneous LCH resembling hidradenitis suppurativa (HS).

Risk factors for tumors or leukemia development in the first two years of life.

OBJECTIVES: The objective of this study was to determine the incidence of neoplastic diseases and associated risk factors in the early stages of life. METHODS: Data were retrospectively assessed in 730,000 live births between 2000 and 2019. The occurrence of tumors was monitored in the neonatal, infant (1-12 months), and toddler (13-24 months) periods. Risk factors were divided into demographic, internal, and environmental factors. The control group consisted of subjects in the same age category without oncological diseases. RESULTS: A total of 452 neoplastic diseases were diagnosed in the study sample. In total, 24% (110/452) manifested during the neonatal period, 45% (203/452) in infants, and 31% (139/452) at the age of 13-24 months. Any genetic disease (OR 26.68; 95% CI 7.64-93.12) and medications used by the mother (OR 3.07; 95% CI 1.32-7.15) were identified as risk factors. Without adjustment for all factors, asphyxia in the first minute, a younger age of the mother, lower pregnancy, and the presence of a congenital defect manifested themselves as risk factors. CONCLUSIONS: The highest risk factors for the development of early childhood tumors were identified as with medications used by the mother before or during pregnancy and genetic diseases.

Current Epidemiology and Co-Infections of Avian Immunosuppressive and Neoplastic Diseases in Chicken Flocks in Central China.

The avian immunosuppressive and neoplastic diseases caused by Marek's disease virus (MDV), avian leucosis virus (ALV), and reticuloendotheliosis virus (REV) are seriously harmful to the global poultry industry. In recent years, particularly in 2020-2022, outbreaks of such diseases in chicken flocks frequently occurred in China. Herein, we collected live diseased birds from 30 poultry farms, out of 42 farms with tumour-bearing chicken flocks distributed in central China, to investigate the current epidemiology and co-infections of these viruses. The results showed that in individual diseased birds, the positive infection rates of MDV, ALV, and REV were 69.5% (203/292), 14.4% (42/292), and 4.7% (13/277), respectively, while for the flocks, the positive infection rates were 96.7% (29/30), 36.7% (11/30), and 20% (6/30), respectively. For chicken flocks, monoinfection of MDV, ALV, or REV was 53.3% (16/30), 3.3% (1/30), and 0% (0/30), respectively, but a total of 43.3% (13/30) co-infections was observed, which includes 23.3% (7/30) of MDV+ALV, 10.0% (3/30) of MDV+REV, and 10.0% (3/30) of MDV+ALV+REV co-infections. Interestingly, no ALV+REV co-infection or REV monoinfection was observed in the selected poultry farms. Our data indicate that the prevalence of virulent MDV strains, partially accompanied with ALV and/or REV co-infections, is the main reason for current outbreaks of avian neoplastic diseases in central China, providing an important reference for the future control of disease.

A rare encounter with two cases of Budd­Chiari syndrome in the Emergency Department: A case report.

Budd-Chiari syndrome (BCS) is a rare disorder clinically characterized by abdominal pain, hepatomegaly and ascites. The condition is often related to thrombosis of the hepatic veins or the terminal portion of the inferior vena cava. A myeloproliferative disorder is the most identified underlying prothrombotic risk factor, although almost one-half of affected patients are now recognized as having multiple underlying prothrombotic risk factors. Doppler ultrasound may be enough to confirm the diagnosis of BCS; however, computed tomography or magnetic resonance imaging is often employed. Anticoagulant therapy is the cornerstone of BCS treatment, but most patients also need additional treatment strategies. Most patients with BCS are now treated by endovascular intervention, which has improved survival rate in those afflicted by this disease. The long-term course of the disease can be complicated by progression or recurrence of the underlying myeloproliferative disorder. The present study reports the cases of two patients with BCS with the aim of alerting healthcare workers in Emergency Departments of this less common diagnosis in patients presenting with frequent complaints of abdominal pain.

Coping with Stress in Neoplastic Diseases.

Introduction: Disease-related stress is a common phenomenon. It also occurs in neoplastic diseases. Since physical and mental health are interrelated, it is important to make sure that treatment covers these two areas. Therefore, it is essential to learn how patients with neoplastic diseases can cope with stress. Materials and Methods: The respondents are 306 patients suffering from neoplastic diseases, associated in patient advocacy groups. The method is the Brief-COPE (Coping Orientation to Problems Experienced) questionnaire. Results: The following stress management strategies were most commonly adopted by the patients: acceptance (median 2.25; 25−75% IQR 2.0−3.0), active coping (median 2.0; 25−75% IQR (interquartile range) 1.5−2.0), planning (median 2.0; 25−75% IQR 2.0−2.0), emotional support (median 2.0; 25−75% IQR 1.5−2.0), instrumental support (median 2.0; 25−75% IQR 2.0−2.0), self-distraction (median 2.0; 25−75% IQR 1.5−3.0), and venting (median 2.0; 25−75% IQR 1.5−3.0). A decision to adopt a particular stress management strategy by patients with neoplastic diseases was highly affected by demographic factors (p < 0.05), such as sex, education, age, place of residence and employment. Conclusions: Teaching stress management strategies should be a part of the education process among patients with neoplastic diseases. Before or in the course of treatment, an oncology patient should be educated on the prevention of mental health disorders. The ability to cope with stress is one of the key competences for the course of neoplastic diseases and it can affect the treatment process. Stress management in chronic diseases, including neoplastic diseases, should be approached not only at the level of an individual person but also at the level of the health system as a whole.

A Review on Mechanistic Insight of Plant Derived Anticancer Bioactive Phytocompounds and Their Structure Activity Relationship.

Cancer is a disorder that rigorously affects the human population worldwide. There is a steady demand for new remedies to both treat and prevent this life-threatening sickness due to toxicities, drug resistance and therapeutic failures in current conventional therapies. Researchers around the world are drawing their attention towards compounds of natural origin. For decades, human beings have been using the flora of the world as a source of cancer chemotherapeutic agents. Currently, clinically approved anticancer compounds are vincristine, vinblastine, taxanes, and podophyllotoxin, all of which come from natural sources. With the triumph of these compounds that have been developed into staple drug products for most cancer therapies, new technologies are now appearing to search for novel biomolecules with anticancer activities. Ellipticine, camptothecin, combretastatin, curcumin, homoharringtonine and others are plant derived bioactive phytocompounds with potential anticancer properties. Researchers have improved the field further through the use of advanced analytical chemistry and computational tools of analysis. The investigation of new strategies for administration such as nanotechnology may enable the development of the phytocompounds as drug products. These technologies have enhanced the anticancer potential of plant-derived drugs with the aim of site-directed drug delivery, enhanced bioavailability, and reduced toxicity. This review discusses mechanistic insights into anticancer compounds of natural origins and their structural activity relationships that make them targets for anticancer treatments.

[Update of the recommendations for the determination of biomarkers in colorectal carcinoma. National Consensus of the Spanish Society of Medical Oncology and the Spanish Society of Pathology]. / Actualización de la recomendación para la determinación de biomarcadores en el carcinoma colorrectal. Consenso Nacional de la Sociedad Española de Oncología Médica y de la Sociedad Española de Anatomía Patológica.

This update of the consensus of the Spanish Society of Medical Oncology (Sociedad Española de Oncología Médica - SEOM) and the Spanish Society of Pathology (Sociedad Española de Anatomía Patológica - SEAP), reviews the advances in the analysis of biomarkers in advanced colorectal cancer (CRC) as well as susceptibility markers of hereditary CRC and molecular biomarkers of localized CRC. Recently published information on the essential determination of KRAS, NRAS and BRAF mutations and the possible benefits of determining the amplification of human epidermal growth factor receptor 2 (HER2), the expression of proteins in the DNA repair pathway and the study of NTRK fusions are also evaluated. From a pathological point of view, the importance of analysing the tumour budding and poorly differentiated clusters and its prognostic value in CRC is reviewed, as well as the impact of molecular lymph node analysis on lymph node staging in CRC. The incorporation of pan-genomic technologies, such as next-generation sequencing (NGS) and liquid biopsy in the clinical management of patients with CRC is also outlined. All these aspects are developed in this guide which, like the previous one, will be revised when necessary in the future.

Emergence of spontaneously occurring neoplastic disease caused by reticuloendotheliosis virus in breeding Muscovy ducks in China, 2019.

Reticuloendotheliosis virus (REV) has a wide range of avian hosts leading to reticuloendotheliosis, and its characteristic of vertical transmission makes it to be one of the most important diseases in breeder avian populations. Up to date, reports on neoplastic disease caused by REV in breeding ducks are few. Here, spontaneously occurring neoplastic disease caused by REV in breeding Muscovy ducks was reported in Guangdong province, China. The most significant gross lesions of sick ducks were tumour-bearing liver and enlarged spleen. Histopathological examination found proliferation of malignant lymphoreticular cells in the liver and reticuloendothelial cells in the spleen. REV strain, CH-GD2019, was successfully isolated using DF-1 cells, and the presence of REV was confirmed by PCR detection and transmission electron microscopy. The length of complete proviral genome is 8,238 nucleotides. Genetic and phylogenetic analyses revealed that CH-GD2019 was closely related to chicken-origin REV strains circulating in China. The results will provide a basic data for better understanding of REV in breeding ducks and suggest that REV from chickens may be a threat to ducks.

Fecal microbiome as determinant of the effect of diet on colorectal cancer risk: comparison of meat-based versus pesco-vegetarian diets (the MeaTIc study).

BACKGROUND: Convincing evidence suggests that the risk of colorectal cancer (CRC) is increased by the typical Western diet characterized by high consumption of red and processed meat. In addition, some epidemiological studies suggest a reduction in the risk of CRC associated with fish consumption. The role of the gut microbiome in this diet-associated risk is not well understood. METHODS/DESIGN: This is a randomized parallel open clinical trial comprising a total of 150 clinically healthy subjects randomly assigned to three groups: a meat-based diet of which 4 portions per week are red meat (1 portion = 150 g), 3 portions per week are processed meat (1 portion = 50 g), and 1 portion per week is poultry (1 portion = 150 g), for a total amount of 900 g per week of meat and derivatives; a meat-based diet supplemented with alpha-tocopherol; and a pesco-vegetarian diet excluding fresh and processed meat and poultry, but which includes 3 portions per week of fish for a total amount of 450 g per week. Each intervention will last 3 months. The three diets will be isocaloric and of three different sizes according to specific energy requirements. Anthropometric measurements, body composition, and blood and fecal samples will be obtained from each participant at the beginning and end of each intervention phase. The measure of the primary outcome will be the change from baseline in DNA damage induced by fecal water using the comet assay in a cellular model. Secondary outcome measures will be changes in the profile of fecal microbiomes, global fecal and urinary peroxidation markers, and neoplastic biomarkers. DISCUSSION: Although epidemiological data support the promoting role of meat and the possible protective role of fish in colon carcinogenesis, no study has directly compared dietary profiles characterized by the presence of these two food groups and the role of the gut microbiome in these diet-associated CRC risks. This study will test the effect of these dietary profiles on validated CRC risk biomarkers. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03416777. Registered on 3 May 2018.

Omega-3 Fatty Acids Prevent Early Pancreatic Carcinogenesis via Repression of the AKT Pathway.

Pancreatic cancer remains a daunting foe despite a vast number of accumulating molecular analyses regarding the mutation and expression status of a variety of genes. Indeed, most pancreatic cancer cases uniformly present with a mutation in the KRAS allele leading to enhanced RAS activation. Yet our understanding of the many epigenetic/environmental factors contributing to disease incidence and progression is waning. Epidemiologic data suggest that diet may be a key factor in pancreatic cancer development and potentially a means of chemoprevention at earlier stages. While diets high in ω3 fatty acids are typically associated with tumor suppression, diets high in ω6 fatty acids have been linked to increased tumor development. Thus, to better understand the contribution of these polyunsaturated fatty acids to pancreatic carcinogenesis, we modeled early stage disease by targeting mutant KRAS to the exocrine pancreas and administered diets rich in these fatty acids to assess tumor formation and altered cell-signaling pathways. We discovered that, consistent with previous reports, the ω3-enriched diet led to reduced lesion penetrance via repression of proliferation associated with reduced phosphorylated AKT (pAKT), whereas the ω6-enriched diet accelerated tumor formation. These data provide a plausible mechanism underlying previously observed effects of fatty acids and suggest that administration of ω3 fatty acids can reduce the pro-survival, pro-growth functions of pAKT. Indeed, counseling subjects at risk to increase their intake of foods containing higher amounts of ω3 fatty acids could aid in the prevention of pancreatic cancer.

[Evaluation and determinants of pain in patients hospitalized for cancer]. / Ocena i uwarunkowania bólu u hospitalizowanych z powodu choroby nowotworowej.

Pain is a symptom that occurs in almost every third person at the time of diagnosis of cancer. Its intensity and frequency increases with the progression of the disease. AIM: The aim of the studywas to determine of pain conditions in patients treated for cancer during oncological treatment. MATERIALS AND METHODS: The study included 229 randomly selected patients hospitalized at Fr. B. Markiewicz Specialist Hospital of the Podkarpacki Oncological Center in Brzozów. The method of the diagnostic survey and the technique of the survey were used. The research tools were the author's questionnaire and the numerical rating scale NRS (Numeric Rating Scale). The statistical analysis used the following tests: U Mann Whitney and symmetric measures Phi and V Kramer based on the chi-square test. The statistical significance level p≤0.05 was assumed. RESULTS: The incidence of pain resulting from neoplastic disease, treatment and the consequences of the disease was declared by 61,6% of patients. The mean severity of pain in patients was 3.38. Middleaged pain was reported by 55.3% of patients. Low level pain occurred in almost every third patient (31.9%) and in severe form in 12.8% of patients. The most frequent places of pain were abdominal cavity, osteoarticular system and head. Painkillers were taken by 59.4% of patients and mainly were drugs from the first stage of analgesic ladder, among them Paracetamol. Morphine - every tenth patient took the drug of the third grade of the analgesic ladder. The pain was not affected by education, age, sex, marital status, place of residence and self-assessment of functioning in everyday life. Patients suffering from pain assessed their health better. CONCLUSIONS: Most individuals with cancer suffered from pain and painkillers, mainly from the first degree of analgesic ladder. The occurrence of pain was not differentiated as for socio-demographic variables. The treatment method was associated with the sensation of pain, the experience of which influenced the self-assessment of health. Pain is a threat to the quality of life and significantly affects the treatment process. Relief and elimination of pain is a priority in the care and treatment of cancer patients.

Spontaneous regression of metastatic squamous cell lung cancer.

Spontaneous regression (SR) of cancer is a rare but confirmed spectacular phenomenon, and it is even rarer in the context of advanced NSCLC. It is essential to understand this phenomenon in order to elucidate the nature of neoplastic disease and develop new treatment methods.
