Supportive care 2030 movement: towards unifying ambitions for global excellence in supportive cancer care-an international Delphi study.

Background: Supportive care to ensure optimal quality of life is an essential component of cancer care and symptom control across the lifespan. Ongoing advances in cancer treatment, increasing toxicity from many novel treatment regimes, and variations in access to care and cancer outcomes across the globe and resource settings present significant challenges for supportive care delivery. To date, no overarching framework has been developed to guide supportive care development worldwide. As an initial step of the Multinational Association of Supportive Care in Cancer (MASCC) Supportive Care 2030 Movement, we developed a targeted, unifying set of ambition statements to envision the future of supportive cancer care. Methods: From September 2022 until June 2023, we used a modified Delphi methodology to develop and attain consensus about ambition statements related to supportive cancer care. Leaders of MASCC Study Groups were invited to participate in an Expert Panel for the first two Delphi rounds (and a preliminary round to suggest potential ambition statements). Patient Advocates then examined and provided input regarding the ambition statements. Findings: Twenty-seven Expert Panelists and 11 Patient Advocates participated. Consensus was attained on 13 ambition statements, with two sub-statements. The ambition statements addressed global standards for guideline development and implementation, coordinated and individualized care, dedicated supportive oncology services, self-management, needs for screening and actions, patient education, behavioral support, financial impact minimization, comprehensive survivorship care, and timely palliative care, reflecting collaboration, coordination and team-based approach across all levels. Interpretation: This study is the first to develop shared ambitions for the future of supportive cancer care on a global level. These ambition statements can facilitate a coordinated, resource-stratified, and person-centered approach and inform research, education, clinical services, and policy efforts. Funding: This project received funding support from Prof Raymond Chan's NHMRC Investigator Grant (APP1194051).

Treating cancer-associated venous thromboembolism: A practical approach.

Venous thromboembolism (VTE) is a common and potentially life-threatening complication in patients with cancer. Both cancer and its treatments increase the risk of developing VTE. Specific cancer types and individual patient comorbidities increase the risk of developing cancer-associated VTE, and the risk of bleeding is increased with anticoagulation therapies. The aims of this article are to summarize the latest evidence for treating cancer-associated VTE, discuss the practical considerations involved, and share best practices for VTE treatment in patients with cancer. The article pays particular attention to challenging contexts including patients with brain, lung, gastrointestinal, and genitourinary tumors and those with hematological malignancies. Furthermore, the article summarizes specific clinical scenarios that require additional treatment considerations, including extremes of body weight, nausea and gastrointestinal disturbances, compromised renal function, and anemia, and touches upon the relevance of drug-drug interactions. Historically, vitamin K antagonists and low-molecular-weight heparins (LMWHs) have been used as therapy for cancer-associated VTE. The development of direct oral anticoagulants has provided additional treatment options, which, in certain instances, offer advantages over LMWHs. There are numerous factors that need to be considered when treating cancer-associated VTE, and although various treatment guidelines are helpful, they do not reflect each unique scenario that may arise in clinical practice. This article provides a summary of the latest evidence and a practical approach for treating cancer-associated VTE.

The Impact of Expert Pathology Review and Molecular Diagnostics on the Management of Sarcoma Patients: A Prospective Study of the Hellenic Group of Sarcomas and Rare Cancers.

Precise classification of sarcomas is crucial to optimal clinical management. In this prospective, multicenter, observational study within the Hellenic Group of Sarcoma and Rare Cancers (HGSRC), we assessed the effect of expert pathology review, coupled with the application of molecular diagnostics, on the diagnosis and management of sarcoma patients. Newly diagnosed sarcoma patients were addressed by their physicians to one of the two sarcoma pathologists of HGSRC for histopathological diagnostic assessment. RNA next-generation sequencing was performed on all samples using a platform targeting 86 sarcoma gene fusions. Additional molecular methods were performed in the opinion of the expert pathologist. Therefore, the expert pathologist provided a final diagnosis based on the histopathological findings and, when necessary, molecular tests. In total, 128 specimens from 122 patients were assessed. Among the 119 cases in which there was a preliminary diagnosis by a non-sarcoma pathologist, there were 37 modifications in diagnosis (31.1%) by the sarcoma pathologist, resulting in 17 (14.2%) modifications in management. Among the 110 cases in which molecular tests were performed, there were 29 modifications in diagnosis (26.4%) through the genomic results, resulting in 12 (10.9%) modifications in management. Our study confirms that expert pathology review is of utmost importance for optimal sarcoma diagnosis and management and should be assisted by molecular methods in selected cases.

Pseudomyxoma Peritonei: A Challenging Clinical Diagnosis. Case Report and Review of the Literature.

Background: Pseudomyxoma peritonei (PMP) is a clinical entity of subtle onset abdominal pain, ascites, and distention associated with characteristic imaging. In most cases, laparoscopic exploration will give the definitive diagnosis and histopathologic verification. However, usually there are difficulties in the diagnosis of this disease. Case Report: Herein, we present a case of a 51-year-old female who developed ascites over 5 months. An investigational laparotomy established the diagnosis of PMP, after the discovery of a mucinous, grey-brown tumor that was CK20 positive and CK7 negative. Subsequently, chemotherapy with oxaliplatin combined with 5-FU (FOLFOX4 regimen), was initiated and the patient survived for 30 months. We also present a comprehensive review of the English literature concerning the different symptoms and radiological findings of this rare entity. According to the literature review, 35 cases of PMP with different clinical and radiological findings have been described. In the majority of the cases, ultrasound, computed tomography or magnetic resonance imaging was orientating towards a proper diagnosis before a diagnostic laparotomy. Conclusion: The combination of a clinical picture with the characteristic imaging findings enables a prompt diagnosis of PMP, making prognosis more favorable.

The Clinical Significance of MicroRNAs in Colorectal Cancer Signaling Pathways: A Review.

Colorectal carcinoma (colon and rectum) is currently considered among the most prevalent malignancies of Western societies. The pathogenesis and etiological mechanisms underlying colorectal cancer (CRC) development remain complex and heterogeneous. The homeostasis and function of normal human intestinal cells is highly regulated by microRNAs. Therefore, it is not surprising that mutations and inactivation of these molecules appear to be linked with progression of colorectal tumors. Recent studies have reported significant alterations of microRNA expression in adenomas and CRCs compared with adjacent normal tissues. This observed deviation has been proposed to correlate with the progression and survival of disease as well as with choice of optimal treatment and drug resistance. MicroRNAs can adopt either oncogenic or tumor-suppressive roles during regulation of pathways that drive carcinogenesis. Typically, oncogenic microRNAs termed oncomirs, target and silence endogenous tumor-suppressor genes. On the other hand, tumor-suppressive microRNAs are critical in downregulating genes associated with cell growth and malignant capabilities. By extensively evaluating robust studies, we have emphasized and distinguished a discrete set of microRNAs that can modulate tumor progression by silencing specific driver genes crucial in signaling pathways including Wnt/b-catenin, epidermal growth factor receptor, P53, mismatch repair DNA repair, and transforming-growth factor beta.

Association of Mediterranean Diet Adherence with Disease Progression Characteristics, Lifestyle Factors and Overall Survival in Gastric Cancer Patients.

BACKGROUND: The Mediterranean diet (MD) exerts a protective effect against cancer development and progression; however, the evaluation of its impact on gastric cancer still remains quite scarce. The present study aims to evaluate the association of MD adherence during the lifespan with disease progression characteristics, lifestyle factors and overall survival in gastric carcinoma patients. METHODS: This is an observational, cross-sectional study conducted on 186 gastric cancer patients followed up for a median time interval of 57 months or until death due to cancer disease. Tumor histopathological characteristics were retrieved from patients' medical records, while validated questionnaires assessing, immediately after the time of diagnosis, health-related quality of life, physical activity levels, sleep quality, depression, anxiety and MD adherence during the lifespan were used. RESULTS: Higher MD adherence during the lifespan was significantly associated with younger patients (p = 0.0106), regular smoking (p < 0.0001), abnormal BMI status (p < 0.0001), intestinal-type gastric carcinoma (p = 0.0111), high tumor histopathological grade (p < 0.0001) and earlier disease stage (p < 0.0001). Moreover, patients with elevated MD adherence during their lifespan showed significantly better health-related quality of life (p < 0.0001), higher physical activity levels (p < 0.0001), more adequate sleep quality (p < 0.0001) and lower prevalence of depression (p = 0.0003) and anxiety (p = 0.0006) compared to those with reduced MD adherence. In multiple regression analysis, elevated MD compliance during the lifespan was independently correlated with longer overall patient survival after adjustment for several confounders (Cox regression analysis, p = 0.0001). CONCLUSIONS: Higher MD adherence during the lifespan was associated with less advanced tumor histopathology characteristics and favorable mental and physical lifestyle factors. Moreover, higher MD adherence during the lifespan was also independently correlated with longer overall survival in gastric carcinoma patients. Thus, adopting a healthy dietary pattern like the MD during the lifespan may act as a preventive agent in combination with a healthy lifestyle against gastric cancer development and progression.

May Nutritional Status Positively Affect Disease Progression and Prognosis in Patients with Esophageal and Pharyngeal Cancers? A Scoping Review of the Current Clinical Studies.

BACKGROUND: Malnutrition in esophageal and pharyngeal cancer patients constitutes a common and serious concern, which significantly reduces patients' prognoses. Cancers of the esophagus and the pharynx can considerably impair feeding in patients, resulting in severe undernutrition. This is a scoping review that intends to critically analyze the most well-designed clinical studies investigating the potential beneficial impact of diverse nutritional assessment tools on the prognosis of patients with esophageal and pharyngeal cancers. METHODS: The most accurate and remarkable scientific databases were comprehensively explored utilizing relative keywords to detect clinical studies that investigate whether nutritional status may affect disease prognosis. RESULTS: Several assessment tools have evaluated and highlighted the potential beneficial impact of nutritional status on disease progression and patients' prognosis in both esophageal and pharyngeal cancers. Regarding esophageal cancer, CONUT, PNI, PG-SGA, and NRS-2002 are more commonly used, while albumin is also frequently evaluated. Regarding pharyngeal cancers, fewer studies are currently available. PNI has been evaluated, and its significance as a factor for shorter survival' times has been highlighted. The Comprehensive Nutritional Index has also been evaluated with positive results, as well as NRS 2002, GPS, and body-weight status. However, there is currently a lack of studies with an adequate number of women with cancer. An international literature gap was identified concerning follow-up studies with adequate methodology. CONCLUSIONS: Nutritional status may significantly affect disease progression and patients' survival, highlighting the significance of a great nutritional status in individuals with esophageal and pharyngeal cancers. Further large-scale and well-designed prospective surveys should be performed to verify the potential beneficial effects of adequate nourishment in people suffering from cancer of the esophagus and pharynx.

Exploring the Use of a Digital Platform for Cancer Patients to Report Their Demographics, Disease and Therapy Characteristics, Age, and Educational Disparities: An Early-Stage Feasibility Study.

INTRODUCTION: The increasing burden of cancer, the development of novel therapies, and the COVID-19 pandemic have made cancer care more complex. Digital innovation was then pushed toward developing platforms to facilitate access to cancer care. Age, education, and other disparities were, however, shown to limit the use of the digital health innovation. The aim of this early-stage feasibility study was to assess whether Greek cancer patients would register at CureCancer and self-report their demographics, disease and therapy characteristics, and socioeconomic issues. The study was organized by the Hellenic Society of Medical Oncology. METHODS: Patients from nine cancer centers were invited to register on the CureCancer platform and complete an anonymous questionnaire on demographics, disease and therapy characteristics, and socioeconomic issues. Patients were also encouraged to upload, in a secure area for them, their medical files and share them with their physicians. They were then asked to comment on their experience of registration and how easy it was to upload their medical files. RESULTS: Of the 159 patients enrolled, 144 (90.56%) registered, and 114 of those (79.16%) completed the questionnaire, suggesting that the study is feasible. Users' median age was 54.5 years, and 86.8% of them were university and high school graduates. Most patients (79.8%) reported their specific type of cancer diagnosis, and all reported their therapy characteristics. Breast and lung cancers were the most common. A total of 87 patients (76.3%) reported being on active cancer therapy, 46 (40.4%) had metastatic disease, and 51 (44.7%) received supportive care medications. Eighty-one (71.05%) patients received prior cancer therapies, and twenty-seven recalled prior supportive care medications. All patients reported visiting non-oncology Health Care Professionals during the study. Nineteen of 72 (26.39%) patients who worked prior to cancer diagnosis changed work status; 49 (42.98) patients had children under 24 years; and 16 (14%) patients lived alone. Nine (7.9%) patients were members of patient associations. Registration was "much/very much" easy for 98 (86.0%) patients, while 67 (58.8%) had difficulties uploading their files. Patients commented on the well-organized data access, improved communication, feeling safe, medication adherence, interventions from a distance, and saving time and money. Over 80% of patients "preferred the digital way". DISCUSSION: A total of 114 patients succeeded in registering on the digital platform and reporting their demographics, disease and therapy characteristics, and socioeconomic issues. Age and educational disparities were disclosed and highlighted the need for educational programs to help older people and people of lower education use digital innovation. Health care policy measures would support patients' financial burden associated with work changes, living alone, and children under 24 years old at school or college. Policy actions would motivate patients to increase their participation in patient associations. According to the evidence DEFINED framework, the number of patients, and the focus on enrollment, engagement, and user experience, the study fulfills actionability level criterion 1.

Molecular Screening for Urothelial Cancer: How Close We Are?

Early detection of urothelial cancer offers the potential for effective and successful treatment. Despite previous efforts, currently, there is not a well-validated, recommended screening program in any country. This integrative, literature-based review provides details on how recent molecular advances may further advance early tumor detection. The minimally invasive liquid biopsy is capable of identifying tumor material in human fluid samples from asymptomatic individuals. Circulating tumor biomarkers (cfDNA, exosomes, etc.) are very promising and are attracting the interest of numerous studies for the diagnosis of early-stage cancer. However, this approach definitely needs to be refined before clinical implementation. Nevertheless, despite the variety of current obstacles that require further research, the prospect of identifying urothelial carcinoma by a single urine or blood test seems truly intriguing.

Metformin: A Promising Radiosensitizer in Neoadjuvant Rectal Cancer Treatment.

BACKGROUND: Neoadjuvant chemoradiotherapy (nCRT) decreases the risk of local recurrence after surgery in patients with locally advanced rectal cancer (LARC) and metformin is constantly gaining scientific interest due to its potentially radiosensitizing effect. OBJECTIVE: This review article aims to better clarify the role of metformin as a radiosensitizer in patients with LARC undergoing neoadjuvant concurrent chemoradiotherapy. METHODS: We used the PubMed database to retrieve journal articles and the inclusion criteria were all human studies that illustrated the effective role of metformin in the neoadjuvant setting of locally advanced rectal cancer. RESULTS: Our search resulted in 17 citations, of which 10 eventually fulfilled the inclusion criteria of our study. Promising results (improved tumor and nodal regression as well as higher pathologic complete response rate) have been occasionally documented with metformin use in some of the included studies. However, regarding survival and all-cause mortality, no significant difference has been found. CONCLUSION: Metformin might constitute a highly promising radiosensitizer in neoadjuvant LARC treatment attracting much scientific interest. Due to the lack of studies with high evidence, further advanced research is required to enhance the existing knowledge about its potential value in this field.

Metachronous Single Pulmonary Metastasis of Prostate Cancer: Report of a Rare Case and Literature Review.

BACKGROUND: Prostate cancer recurrence after definitive local therapy usually involves the bone and regional lymph nodes. CASE REPORT: We present the case of a 72-year-old male patient with an isolated lung nodule, seven years after radical prostatectomy for prostate cancer, pT2bN0 and Gleason score 7(4+3), and prostatic-specific antigen (PSA) levels within normal limits. The nodule was considered as a primary lung cancer and the patient was subjected to lobectomy. The immunohistochemical staining showed that the tumor was PSA(+) and NKX3.1 (+), revealing that it was metastasis from prostatic cancer and that wedge resectomy was the proper procedure. Three years later the patient is disease-free, suggesting the importance of aggressive treatment of oligometastatic disease. CONCLUSION: Metastasis to the lung is present in more than 40% of men with metastatic prostate cancer; however, lung metastases without any bone or lymph node involvement are extremely rare and only a handful of cases are reported in the literature. Surgical excision of the metastatic lung site is the most common therapeutic approach associated with a good prognosis.

Factors associated with anxiety and depression in cancer patients: Demographic factors and the role of demoralization and satisfaction with care.

OBJECTIVE: Anxiety and depression are common in cancer patients and seem to affect quality of life, treatment compliance and even survival. Defining factors related to anxiety and depression and exploring the role of demoralization and satisfaction with care, could contribute to the improvement of patients' quality of life and quality of health services as well. METHODS: A convenience sample of 150 cancer inpatients and outpatients from two oncology centers, with various types of solid tumors, participated in a prospective cross-sectional observational study. The psychometric tools used were the Greek versions of the Hospital Anxiety and Depression Scale, FAMCARE-Patient Scale and Oncology Palliative Care (FAMCARESCALE) and Demoralization Scale (DEMORALIZATION SCALE II, DS-II). RESULTS: Patients mean age was 62 years (20-85 years) and 89 patients (59.3%) were women. Among patients, 33% had breast, 24% gastrointestinal and 15% lung cancer. Eighty-two patients (54.7%) had metastatic disease. Women showed higher rates of anxiety (p = 0.054). Anxiety was inversely related to age (p = 0.043) and positively correlated with time since diagnosis (p = 0.076). Unmarried patients presented with higher rates of depression (p = 0.026). Multiple linear regression showed a statistically significant impact of Demoralization factor 'Meaning and Purpose' on anxiety (p < 0.001, R2  = 36.3%) and depression (p < 0.001, R2  = 49%). Moreover, higher educational level (p = 0.038, R2  = 3.1%) is related to higher levels of anxiety and higher scores of FAMCARESCALE factor-Information/interaction with the health care professionals, is related to lower levels of depression (p = 0.008, R2  = 2.7%). CONCLUSIONS: The results highlight the significant impact of demoralization on anxiety and depression in cancer patients. Early recognition of demoralization and early referral to mental health professionals will hopefully alleviate the mental burden of cancer patients.

Molecular Epidemiology and Treatment Patterns of Patients With EGFR Exon 20-Mutant NSCLC in the Precision Oncology Era: The European EXOTIC Registry.

Introduction: Real-world evidence regarding molecular epidemiology and management patterns of patients with EGFR exon-20 mutated, advanced NSCLC outside the context of clinical trials is lacking. Methods: We created a European registry for patients with advanced EGFR exon 20-mutant NSCLC diagnosed from January 2019 to December 2021. Patients enrolled in clinical trials were excluded. Clinicopathologic and molecular epidemiology data were collected, and treatment patterns were recorded. Clinical end points according to treatment assignment were assessed using Kaplan-Meier curves and Cox regression models. Results: Data on 175 patients from 33 centers across nine countries were included in the final analysis. Median age was 64.0 (range: 29.7-87.8) years. Main features included female sex (56.3%), never or past smokers (76.0%), adenocarcinoma (95.4%), and tropism for bone (47.4%) and brain (32.0%) metastases. Mean programmed death-ligand 1 tumor proportional score was 15.8% (range: 0%-95%) and mean tumor mutational burden was 7.06 (range: 0-18.8) mutations per megabase. Exon 20 was detected in the tissue (90.7%), plasma (8.7%), or both (0.6%), using mostly targeted next-generation sequencing (64.0%) or polymerase chain reaction (26.0%). Mutations were mainly insertions (59.3%), followed by duplications (28.1%), deletions-insertions (7.7%), and the T790M (4.5%). Insertions and duplications were located mainly in the near loop (codons 767-771, 83.1%) and the far loop (codons 771-775, 13%) and only in 3.9% within the C helix (codons 761-766). Main co-alterations included mutations in TP53 (61.8%) and MET amplifications (9.4%). Treatment on mutation identification included chemotherapy (CT) (33.8%), CT-immunotherapy (IO) (18.2%), osimertinib (22.1%), poziotinib (9.1%), mobocertinib (6.5%), mono-IO (3.9%), and amivantamab (1.3%). Disease control rates were 66.2% with CT plus or minus IO, 55.8% with osimertinib, 64.8% with poziotinib, and 76.9% with mobocertinib. Corresponding median overall survival was 19.7, 15.9, 9.2, and 22.4 months, respectively. In multivariate analysis, type of treatment (new targeted agents versus CT ± IO) affected progression-free survival (p = 0.051) and overall survival (p = 0.03). Conclusions: EXOTIC represents the largest academic real-world evidence data set on EGFR exon 20-mutant NSCLC in Europe. Indirectly compared, treatment with new exon 20-targeting agents is likely to confer survival benefit than CT plus or minus IO.

Safety and efficacy of immunotherapy rechallenge following checkpoint inhibitor-related pneumonitis in advanced lung cancer patients: a retrospective multi-center cohort study.

Background: Checkpoint inhibitor-related pneumonitis (CIP) induced by immune checkpoint inhibitors (ICIs) is one of the most fatal immune-related adverse events (irAE). However, only limited data are available on rechallenge with ICIs after CIP. We evaluated the efficacy and safety of rechallenge after CIP in patients with advanced lung cancer to identify the potential populations that would benefit. Methods: We conducted a multicenter retrospective study of advanced lung cancer patients who received further ICI treatment (rechallenge) or did not undergo re-administration after grade ≥1 CIP between May 2017 and May 2021. Progression-free survival (PFS) and overall survival (OS) were estimated from first or second ICI initiation to disease progression (PFS1 and PFS2, respectively), death, or last follow-up (OS1 and OS2, respectively). The recurrence of CIP and new irAEs in these patients after ICI rechallenge were calculated. Results: Among 107 patients afflicted with CIP, 45 (42.1%) received ICI rechallenge. Multivariate analysis showed that severe grade (grades ≥3) and ground-glass opacity of pneumonitis lesions were negatively associated with rechallenge. Following rechallenge, 9 (20.0%) patients developed recurrent pneumonitis, and 11 (24.4%) developed a new irAE. Severe grade of CIP and poor performance status at initial CIP as well as levels of interleukin (IL)-6 and C-reactive protein (CRP), and absolute white blood cell and neutrophil counts at the time of ICI rechallenge were associated with a higher recurrence rate. The median (95% confidence interval) PFS1 and PFS2 were 17.9 (9.9-24.2) and 15.5 (5.5-25.6) months, respectively. The median (95% confidence interval) OS1 and OS2 were 23.5 (16.5-30.5) and 18.4 (10.1-26.7) months, respectively. Lower OS2 was observed in patients with severe grade of CIP and poor performance status at the initial CIP, recurrence of CIP, and in patients with high levels of CRP and IL-6 at rechallenge. Only IL-6 was found to affect OS2 on multivariate analysis. Conclusions: ICI rechallenge following CIP may be a promising treatment for patients with advanced lung cancer, particularly in those with low-grade of CIP and good performance status at initial CIP, and low levels of IL-6 and CRP at the time of initial challenge. Prospective studies are needed for further verification.

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.

Synchronous duodenal neuroendocrine neoplasm and congenital factor XIII deficiency: case report and review of the literature.

Background: Neuroendocrine neoplasms (NENs) are uncommon, with duodenal NENs (dNENs) being particularly rare in clinical practice. Congenital factor XIII deficiency (FXIIID) is also an extremely rare hematological disease in which poor wound healing may occur due to coagulopathy. The concurrent occurrence of these two rare diseases has not been reported before, which increases the difficulty of diagnosis and treatment. This is the first report of dNEN concomitant with Congenital FXIIID, which can present as a reference for clinicians who may encounter similar situations in the future. Case Description: We report a 33-year-old woman with bleeding diathesis since childhood who complained of digestive tract bleeding for 7 years. She was finally diagnosed as duodenal neuroendocrine neoplasm combined with congenital factor XIII deficiency. The patient underwent surgery, and pathological findings confirmed neuroendocrine tumor. After surgery she received cryoprecipitate and fresh frozen plasma (FFP) therapy. No tumor recurrence has been observed nor recurrence of digestive tract bleeding during the 2-year follow-up. Conclusions: Our report suggests when gastrointestinal bleeding is difficult to explain, more general examinations in addition to gastroscopy should be performed. In situations where digestive tract bleeding cannot be fully explained by a single disease, the possibility of concomitant disease, such as hematological disorders, should be considered to avoid the missed diagnosis of rare co-morbidities.

Validation of Patras Immunotherapy Score model for prediction and prognosis of patients with advanced NSCLC treated with nivolumab or pembrolizumab: results from a European multicentre study.

Background: Recently, the Patras Immunotherapy Score (PIOS) has been developed to estimate the survival benefit of patients with advanced non-small-cell lung cancer (aNSCLC) treated with nivolumab or pembrolizumab. The aim of this study was to validate the clinical value of PIOS in an external cohort of aNSCLC patients. Methods: PIOS is a baseline formula produced by the combination of performance status, body mass index, age and line of treatment. In this multicentre study, 626 patients with confirmed NSCLC pathology, who had been treated with nivolumab or pembrolizumab, as well as 444 patients with aNSCLC, who had been managed with chemotherapy alone, were retrospectively enrolled. Predictive and prognostic values of PIOS were finally evaluated. Results: Patients treated with immunotherapy and higher PIOS score had an improved progression-free survival not only in univariate [hazard ratio (HR) = 0.621, p = 0.001], but also in multivariable analysis (HR = 0.651, p = 0.003). In addition, improved overall survival with increasing PIOS score was also observed (HR = 0.608, p < 0.001) with this association remaining statistically significant after adjusting for programmed-cell death ligand 1 (PD-L1) expression (HR = 0.620, p < 0.001). In addition, patients with disease progression (PD) had lower scores compared to those with stable disease (SD), partial response (PR) or complete response (CR) in a two-tier model (p < 0.001) as well as in a four-tier model (PD, SD, PR and CR; p < 0.001). Prognostic significance of PIOS score also persisted using a binary logistic regression analysis, adjusted for disease stage and PD-L1 status (p = 0.002, odds ratio: 0.578). Contrarily, PIOS had no prognostic significance in the chemotherapy group; however, upon combined analysis of the two cohorts, PIOS was found to have a significant interaction with the type of treatment (HR = 0.066 with p < 0.001), confirming its predictive value for immunotherapy. Conclusions: This study provides further validation of PIOS in aNSCLC patients treated with anti-PD-1 monotherapy.

Catheter-related thrombosis (CRT) in patients with solid tumors: a narrative review and clinical guidance for daily care.

Central venous access devices (CVADs) including central venous catheters and peripherally inserted central catheters (PICCs) are essential in the treatment of cancer. Catheter-related thrombosis (CRT) is the most frequent non-infectious complication associated with the use of central lines. The development of CRT may cause to delays in oncologic treatment and increase morbidity leading to potentially life-threatening complications. Several local and systemic risk factors are associated with the development of CRT and should be taken into account to prevent CRT by standardizing appropriate catheter placement and maintenance. The use of primary pharmacological thromboprophylaxis in order to avoid CRT is not routinely recommended, although it can be considered in selected cases. Recommendations for the management of established CRT are based on the extrapolation of anticoagulation for lower limb venous thrombosis. The present review summarizes the current evidence and recommendations for the prevention and management of CRT and identifies areas that require further research.

Complexity and clinical significance of drug-drug interactions (DDIs) in oncology: challenging issues in the care of patients regarding cancer-associated thrombosis (CAT).

Cancer patients have an increased risk of developing venous thromboembolic events. Anticoagulation management includes prophylactic or therapeutic doses of low molecular weight heparins (LMWHs) or direct oral anticoagulants (DOACs). However, the management of thrombosis in patients with cancer is complex due to various individual and disease-related factors, including drug-drug interactions (DDIs). Furthermore, DDIs may impact both, cancer and venous thrombosis, treatment effectiveness and safety; their relevance is highlighted by the advances in cancer therapeutics. Given that these new oncology drugs are extensively used, more attention should be given to monitoring potential DDIs to minimize risks. Recognition of DDIs is of utmost importance in an era of rapid developments in cancer treatments and introduction of novel treatments and protocols. When managing cancer-associated thrombosis (CAT), the concomitant use of a DOAC and a moderate or strong modulator (inhibitor or inducer) of CYP3A4 or a P-glycoprotein (P-gp) is most likely to be associated with significant DDIs. Therefore, LMWHs remain the first-line option for the long-term management of CAT under these circumstances and physicians must consider utilizing LMWHs as first line. This review describes the risk of DDIs and their potential impact and outcomes in patients with cancer associated thrombosis (CAT) receiving anticoagulation.

Inpatient primary prophylaxis of cancer-associated thromboembolism (CAT).

PURPOSE: Cancer-associated thrombosis (CAT) increases morbidity and mortality in oncology patients. The risk of CAT is increased with hospitalization for acute medical illness. The goal of this review will be to examine the available evidence for (1) risk assessment and (2) primary thromboprophylaxis, (3) international published guideline recommendations, and (4) future directions to manage oncology patients admitted for an acute medical illness. METHODS: A review was performed for each subject to gather information on the available evidence and recommendations available for oncology patients hospitalized for an acute medical illness. RESULTS: Risk assessments for thrombosis are primarily developed and validated in the general population. There is not a risk assessment that has specifically been developed and validated in oncology patients hospitalized for an acute medical illness. Most evidence for thromboprophylaxis of oncology patients is from sub-group analysis of larger randomized-controlled trials in the general population. Evidence is conflicting and suggests an individualized approach evaluating the risk-benefit of thromboprophylaxis. The strength of recommendations of international guidelines is limited because of the available evidence. Guidelines usually recommend utilizing and/or offering thromboprophylaxis to oncology patients hospitalized for an acute medical illness barring contraindications. Future evidence needs to improve risk assessments and knowledge of the appropriate agent, dose, and duration of thromboprophylaxis if indicated. CONCLUSION: Evidence for risk assessments and primary prophylaxis for oncology patients hospitalized for acute medical illness appears limited, with many research opportunities available to improve understanding on management of this patient population.
