Global coverage and consistency of guideline recommendations for cancer cachexia on the Web in 2011 and 2018.

INTRODUCTION: Cancer cachexia is a common associate of cancer and has a negative impact on both patients' quality of life and overall survival. Nonetheless its management remains suboptimal in clinical practice. Provision of medical recommendations in websites is of extreme importance for medical decision making and translating evidence into clinical practice. AIM OF THE STUDY: To scrutinize the magnitude, consistency and changes over time of cancer-cachexia recommendations for physicians on the Web among oncology related societies. Intercontinental, continental, national and socioeconomic variations were further analyzed. MATERIAL AND METHODS: Web identification of oncology related societies and prospective analyses of relative Web guideline recommendations for physicians on cancer-cachexia at different time-points. RESULTS: In June 2011, we scrutinized 144,000 Web pages. We identified 275 societies, of which 270 were eligible for analyses: 67 were international (African, American, Asian, European, Oceania and Intercontinental), 109 belonged to the top 10 countries with the highest development index and 94 pertained to 10 countries with a long lasting tradition in medical oncology. CONCLUSIONS: The magnitude of cancer cachexia recommendations for physicians on the Web at a global level was scant both for coverage and consistency, and at any time-point considered: 3.7% (10/270) in 2011 and 8.1% (22/270) in 2018. The proportion of societies giving evidence-based and updated recommendations for cancer cachexia for physicians was only 1.1% (3/270) in 2011 and 2.96% (8/270) in 2018. Continent, national highest developmental index, oncology tradition and economic-geographic areas were not found to influence Web guideline provision.

Exploring Immune-Related Adverse Events: A Case of Febrile Neutropenia in a Melanoma Patient Receiving Immunotherapy.

Introduction: The introduction of immune checkpoint inhibitors (ICIs) has opened a new chapter in cancer treatment. Nevertheless, their use may result in immune-related adverse events (irAEs) with multifactorial determinants, complex mechanisms, and varying clinical implications. In specific cancer types, like melanoma, irAEs exhibit a complex relationship with patient outcomes. Case Presentation: We present a case of febrile neutropenia following ICI therapy in a patient with metastatic melanoma, underscoring the intricate clinical landscape associated with irAEs in the context of cancer immunotherapy. More specifically, a 68-year-old man was diagnosed with metastatic malignant melanoma and administered a combination of nivolumab and ipilimumab. However, after a single dose, the patient was hospitalized due to febrile neutropenia. The patient eventually recovered, but a diagnosis of myelosuppression related to prior immunotherapy led to treatment discontinuation. Subsequently, the patient transitioned to a second-line therapy. Conclusion: This case contributes to our comprehension of rare yet potentially severe hematological irAEs and their influence on immunotherapy outcomes. Such insights will guide future diagnostic and therapeutic strategies in the field of immunotherapy.

Exploring a Rarity: Incidence of and Therapeutic Approaches for Neurological Complications and Hypophysitis in Cancer Patients on Immune Checkpoint Inhibitors-A Single-Center Study.

Immune checkpoint inhibitors, such as anti-PD-1 and anti-CTLA-4 inhibitors, have become the standard of care for many cancer types. However, they induce immune-related adverse events (irAEs), including neurotoxicity and hypophysitis. The incidence and outcomes of neurotoxicity and hypophysitis in patients treated with immune checkpoint inhibitors are not well established. We conducted a retrospective study of 812 patients with solid cancers who received immune checkpoint inhibitors at the University General Hospital of Ioannina between January 2018 and January 2023. We assessed demographic and clinical data, including the severity of symptoms, treatment regimen, other irAEs, resolution type and time, and death. Two patients experienced neurotoxicity and two hypophysitis. All four patients required inpatient administration and received corticosteroids or/and hormone replacement. Three patients responded to the initial therapy, experiencing full recovery, while one patient was corticosteroid-resistant, and immunoglobin G was administered. Two patients never received immunotherapy after their toxicity due to the severity of symptoms; one patient continued monotherapy with nivolumab, changing from combination therapy with ipilimumab-nivolumab, while the fourth patient continued his initial treatment with nivolumab. Our study suggests that the incidence of neurotoxicity and hypophysitis in patients treated with immune checkpoint inhibitors is low, but careful monitoring and prompt treatment with corticosteroids are necessary for effective management.

The Utility of NGS Analysis in Homologous Recombination Deficiency Tracking.

Several tumor types have been efficiently treated with PARP inhibitors (PARPis), which are now approved for the treatment of ovarian, breast, prostate, and pancreatic cancers. The BRCA1/2 genes and mutations in many additional genes involved in the HR pathway may be responsible for the HRD phenomenon. The aim of the present study was to investigate the association between genomic loss of heterozygosity (gLOH) and alterations in 513 genes with targeted and immuno-oncology therapies in 406 samples using an NGS assay. In addition, the %gLOHs of 24 samples were calculated using the Affymetrix technology in order to compare the results obtained via the two methodologies. HR variations occurred in 20.93% of the malignancies, while BRCA1/2 gene alterations occurred in 5.17% of the malignancies. The %LOH was highly correlated with alterations in the BRCA1/2 genes, since 76.19% (16/21) of the BRCA1/2 positive tumors had a high %LOH value (p = 0.007). Moreover, the LOH status was highly correlated with the TP53 and KRAS statuses, but there was no association with the TMB value. Lin's concordance correlation coefficient for the 24 samples simultaneously examined via both assays was 0.87, indicating a nearly perfect agreement. In conclusion, the addition of gLOH analysis could assist in the detection of additional patients eligible for treatment with PARPis.

Genetic Predisposition to Male Breast Cancer: A Case Series.

BACKGROUND/AIM: Male breast cancer (MBC) is a very rare disorder affecting approximately 1 in 833 men. Genetic predisposition is one of the most important risk factors of MBC with BRCA2 being the most commonly mutated gene in males diagnosed with breast cancer. However, a large part of MBC heritability is still unexplained. This study sought to add to the data already available on the genetics of MBC. MATERIALS AND METHODS: Our study initially involved comprehensive analysis of BRCA1 and BRCA2, followed by analysis of 43 genes implicated in cancer predisposition in a series of 100 Greek patients diagnosed with MBC between 1995-2015. RESULTS: Pathogenic variants were identified in 13 patients, with BRCA2 being the most commonly affected gene, followed by BRCA1, RAD50, RAD51B, and MSH3. CONCLUSION: In agreement with previous reports, BRCA2 is the most important genetic factor of MBC predisposition, while the remaining known cancer predisposition genes are each very rarely involved, rendering conclusions as to their cumulative effect difficult to draw.

Ureteral carcinoma metastasizing to the testicle: Can misdiagnosis of orchiepididymitis be avoided?

Testicular metastases from ureteral carcinoma are rare and they are generally mimic orchiepididymitis. For this reason, these are associated to misleading diagnoses and cancer treatment delay. We believe that both timing and knowledge of genital blood and lymph reverse flow routes may represent two important parameters for avoiding misleading diagnoses and speed proper anticancer treatment. We describe a case and discuss pathophysiological data and relevant literature.

Interior Design: A New Perspective in Supportive Care of Patients with Acute Onset of Debilitating Diseases.

Background: Upon the onset of a debilitating rapidly evolving condition (such as cancer or a rapidly progressing myopathy, neuropathy, respiratory disease, or a severe traumatic injury), individuals have limited time to find a new home or make radical structural modifications in their residence. How the affected patients can continue sharing the same house with their families, while meeting their own special requirements, is thus rising as a critical issue. Household and daily routine rearrangements, either temporary or permanent, may be necessary, to ameliorate the life of patients with impairments, lasting for months or even years. Objectives: Interior design may provide a highly efficient "living" palliation for debilitating medical conditions directly at patients' home-site. Methods: Research of relevant literature, using keywords "debilitating conditions," "home care," "end of life care," "care of advanced cancer patients," "care of patients with mental disorders," "home care of covid-19 affected patients," and "care of patients with degenerative illnesses." Results: We found that patients and their relatives may not be aware of the probable interior design solutions to their daily life challenges, imposed by a disease-related impairment. In parallel, interior design experts may equally be unaware of these issues, as well as of who needs the available solutions.Similarly, medical and architectural sciences are not connected, eventually failing to meet patients' everyday needs. Conclusions: Interior architecture and health scientists are called to cooperate, aiming to provide a highly efficient and meaningful support to patients and families affected by unforeseen debilitating medical conditions.

Personality variables are associated with colorectal cancer patients' quality of life independent of psychological distress and disease severity.

OBJECTIVE: The aim of the present study was to test whether psychological distress and personality variables are independently associated with health-related quality of life (HRQOL) in colorectal cancer patients, after adjusting for age, gender, education and disease severity. METHODS: In a cross-sectional study of 162 colorectal cancer patients (response rate 65.6%), the following self-report instruments were administered: the Symptom Distress Checklist-90-R, the Sense of Coherence scale, the Life Style Index and the Hostility and Direction of Hostility Questionnaire. The outcome measures were the four components of the WHO Quality of Life Instrument, Short Form. We used hierarchical regressions to determine whether psychological distress mediates the relationship of personality and disease parameters with HRQOL. RESULTS: The overall proportion of the variance in the four components of HRQOL explained by our regression models ranged from 28.1 to 44.4%. Psychological distress was an independent correlate of HRQOL, associated with physical (p<0005), mental (p<0.05) and social relationships HRQOL (p<0.02). Personality variables were associated with HRQOL independent of psychological distress and disease severity. Sense of coherence and denial defense were positively associated with all aspects of HRQOL independent of psychological distress and disease parameters (p-values ranging from p<0.05 to p<0.0005). Hostility (p<0.01) and repression defense (p=0.024) were also independently but negatively associated with physical HRQOL. CONCLUSIONS: In colorectal cancer patients, psychological distress is associated with HRQOL independent of disease parameters but personality variables are also associated with HRQOL independent of disease severity and psychological distress, and this could be relevant to psychological interventions.

Chemotherapy Associated Ovarian Failure.

As the incidence of malignancies in young adults is increasing, fertility preservation in cancer survivors arises as a major concern. Especially among female cancer patients, pregnancy rates are estimated to be 40% lower compared to women of the same age. Nowadays oncologists are to be preoccupied not only with their patients' successful treatment, but also with the maintenance of the potential of the latter to conceive and obtain children. Chemotherapy associated ovarian failure (COF), refers to disruption of ovarian function both as an endocrine gland and as a reproductive organ, due to previous exposure to chemotherapy agents. Although the underlying mechanism is not fully understood, it is supposed that chemotherapy agents may induce either DNA damage of premature ovarian follicle or early activation and apoptosis of them, resulting into early exhaustion of available follicle deposit. Various chemotherapy agents have been associated with COF with the highest incidence being reported for patients undergoing combination regimens. Although a variety of alternatives in order to maintain ovarian function and fertility in female cancer survivors are available, adequately established practices to do so are lacking. Thus, it is of major importance to investigate further and collect sufficient evidence, aiming to guide patients and physicians in everyday clinical practice.

Interior design in cancer care: simple structural solutions in storey houses improve patients' quality of life, mood and performance.

Storey duplex houses are today one of the fastest growing housing market. The key of success is that this kind of house architecture presents esthetic and practical advantages in the average family daily life, but its narrow indoor staircase connecting the ground floor (floor of family activities) to the "bedroom floor" may constitute a potential detriment for the care and quality of life of patients with advanced cancer. Due to cancer cachexia, cancer pain and asthenia, the patients' incapacity to use narrow stairs will become soon an impassable barrier. Alone at the bedroom floor in solitude, depression, months /years exclusion from family daily life, and incapacity to reach medical care services harm not only their quality of life but also the same survival outcome. Creation of a provisional functional room at the ground floor (by low cost easily-removable aluminum door and aluminum panels) enambles patients to return to family life, improve their mood, quality of life and likely survival. Concluding, in the era of storey houses housing markets, homify and interior architecture design interventions may represent a new cost-effective horizon in cancer care.

Molecular findings reveal possible resistance mechanisms in a patient with ALK-rearranged lung cancer: a case report and literature review.

Background: Non-small-cell lung cancer (NSCLC) is recognised as a particularly heterogeneous disease, encompassing a wide spectrum of distinct molecular subtypes. With increased understanding of disease biology and mechanisms of progression, treatment of NSCLC has made remarkable progress in the past two decades. Molecular testing is considered the hallmark for the diagnosis and treatment of NSCLC, with liquid biopsies being more and more often applied in the clinical setting during the recent years. Rearrangement of the ALK gene which results in the generation of fusion oncogenes is a common molecular event in NSCLCs. Among ALK fusion transcripts, EML4-ALK fusion is frequently observed and can be targeted with ALK tyrosine kinase inhibitors (TKI). However, acquired resistance and disease progression in many cases are inevitable. Method: Here, we present the case of a patient with NSCLC treated with TKIs, in which molecular profiling of the tumour was performed with different methods of tissue and plasma testing at each disease progression. A review of the literature was further conducted to offer insights into the resistance mechanisms of ALK-rearranged NSCLC. Conclusions: Based on the results, the EML4-ALK fusion initially detected in tumour tissue was preserved throughout the course of the disease. Two additional ALK mutations were later detected in the tissue and plasma and are likely to have caused resistance to the administered TKIs. Continued research into the mechanisms of acquired resistance is required in order to increase the benefit of the patients treated with targeted ALK TKIs.

Facing internet fake-medicine and web para-pharmacy in the total absence of official recommendations from medical societies.

PURPOSE: Internet fake information, parapharmacy and counterfeit drugs are a market of hundreds of billion dollars. Misleading internet data decrease patients' compliance to medical care, promote use of questionable and detrimental practices, and jeopardize patient outcome. This is particularly harmful among cancer patients, especially when pain and nutritional aspects are considered. Provision of Web recommendations for the general audience (patients, relatives, general population) from official medical-providers might be useful to outweigh the detrimental internet information produced by non-medical providers. METHODS: 370 oncology and anesthesiology related societies were analyzed. Our objective was to evaluate the magnitude of web-recommendation for cancer cachexia and cancer pain for the general audience provided by official medical organizations' web sites at global level. RESULTS: Magnitude of web-recommendations at global level was surprisingly scant both for coverage and consistency. Seven official medical societies provided updated web-recommendation for cancer cachexia to their patients/family members, and 15 for cancer pain. Scantiness was unrelated by continent, developmental index, oncology tradition, economic-geographic area and society type scrutinized. CONCLUSIONS: Patients need expert advice when exposed to fake internet information largely dominated by paramedical market profits. In this era of "new media" the patients' net-education represents a new major educational challenge for medical societies.

Clonal evolution of colorectal cancer in a patient with serially resected metastases and liquid biopsies: a case report and discussion of the literature.

BACKGROUND: Metastatic colorectal cancer represents a striking example of clonal heterogeneity and tumour evolution, which generates acquired resistance to therapy. Once hard to perform, the study of clonal heterogeneity is now significantly aided by the use of liquid biopsies. METHOD: We herein report a case of a patient with colorectal cancer and serial development of multiple metastases which were all resected and genotyped. A rare point mutation was identified in the primary tumour (but not in any of the organ metastatic sites), as well as in the first and the last out of three consecutive liquid biopsies. The review of the literature offered some insight in the evolution of the patient's tumour and general directions on how to interpret liquid biopsy results. CONCLUSIONS: This patient case emphasises the need for large prospective studies designed to bridge liquid biopsy data with useful clinical endpoints, in order to optimally integrate this revolutionary tool in everyday practice.

Comprehensive molecular screening by next generation sequencing reveals a distinctive mutational profile of KIT/PDGFRA genes and novel genomic alterations: results from a 20-year cohort of patients with GIST from north-western Greece.

INTRODUCTION: Gastrointestinal stromal tumours (GIST) are mesenchymal neoplasms that usually carry an activating mutation in KIT or platelet-derived growth factor receptor alpha (PDGFRA) genes with predictive and prognostic significance. We investigated the extended mutational status of GIST in a patient population of north-western Greece in order to look at geopraphic/genotypic distinctive traits. PATIENT AND METHODS: Clinicopathological and molecular data of 38 patients diagnosed from 1996 to 2016 with GIST in the region of Epirus in Greece were retrospectively assessed. Formalin-fixed paraffin-embedded tumours were successfully analysed for mutations in 54 genes with oncogenic potential. Next generation sequencing was conducted by using the Ion AmpliSeqCancer Hotspot Panel V.2 for DNA analysis (Thermofisher Scientific). RESULTS: Among 38 tumours, 24 (63.16%) and seven (18.42%) of the tumours harboured mutations in the KIT and PDGFRA genes, respectively, while seven (18.42%) tumours were negative for either KIT or PDGFRA mutation. No mutations were detected in five (13.16%) cases. Concomitant mutations of BRAF and fibroblast growth factor receptor 3 (FGFR3) genes were observed in two patients with KIT gene mutation. Two patients with KIT/PDGFRA wild-type GIST had mutations in either KRAS or phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) genes. There was no significant survival difference regarding the exonic site of mutation in either KIT or PDGFRA gene. The presence of a mutation in pathway effectors downstream of KIT or PDGFRA, such as BRAF, KRAS or PIK3CA, was associated with poor prognosis. Adverse prognosticators were also high mitotic index and the advanced disease status at diagnosis. CONCLUSIONS: We report comparable incidence of KIT and PDGFRA mutation in patients with GIST from north-western Greece as compared with cohorts from other regions. Interestingly, we identified rare mutations on RAS, BRAF and PIK3CA genes in patients with poor prognosis.

Aromatase inhibitors induced autoimmune disorders in patients with breast cancer: A review.

Subacute cutaneous lupus erythematosus (SCLE) is characterized by particular cutaneous manifestations such as non-scaring plaques mainly in sunlight exposed parts of the body along with specific serum autoantibodies (i.e. antinuclear antibodies (ANA), Ro/SSa, La/SSb). It is considered either idiopathic or drug induced. The role of chemotherapeutic agents in causing SCLE has been investigated with the taxanes being the most common anticancer agents. However, recent data emerging point toward antiestrogen therapies as a causative factor not only for SCLE but also for a variety of autoimmune disorders. This is a report of a case of a 42 year old woman who developed clinical manifestations of SCLE after letrozole treatment in whom remission of the cutaneous manifestations was noticed upon discontinuation of the drug. In addition, an extensive review of the English literature has been performed regarding the association of antiestrogen therapy with autoimmune disorders. In conclusion, Oncologists should be aware of the potential development of autoimmune reactions in breast cancer patients treated with aromatase inhibitors.

Personality variables as predictors of early non-metastatic colorectal cancer patients' psychological distress and health-related quality of life: a one-year prospective study.

OBJECTIVE: We aimed to assess the course of early non-metastatic colorectal cancer patients' psychological distress and health-related quality of life (HRQOL) and to identify relevant clinical and psychological predictors during a one-year period. METHODS: Of the 144 early non-metastatic colorectal cancer patients initially assessed for psychological distress symptoms (SCL-90-R), HRQOL (WHOQOL-BREF), sense of coherence (SOC), defense mechanisms (LSI) and hostility (HDHQ), 84 (58.3%) completed the one-year follow-up. Mean (SD) age was 65.1 (9.8) years and 67.4% were male. Mean (SD) disease duration was 1.7 (2.2) years, with 49.3% being diagnosed within the last six months. In 75.0% the site was at colon and in 25.0% at rectum; 2.1% had stage I, 59.0% stage II and 38.9% stage III disease. RESULTS: Paranoid ideation, psychoticism, interpersonal sensitivity, anxiety and depressive symptoms increased significantly over the one-year period of the study and most of the HRQOL components were significantly decreased over the same period. Men were at greater risk for further developing depressive symptomatology. Low SOC was independent predictor of depression, while hostility independently predicted anxiety, interpersonal sensitivity and psychoticism symptoms. General psychological distress and low SOC were independent predictors of HRQOL, while repression was also an independent predictor of Physical HRQOL. CONCLUSIONS: In early non-metastatic colorectal cancer patients, psychological distress symptoms are increased and HRQOL is decreased over one-year period. Symptoms of psychological distress are strong predictors of HRQOL, while personality variables can also predict psychological distress symptoms' increase and HRQOL decrease over time, and this could be relevant to psychological interventions.
