Analysis of immune checkpoint inhibitors for advanced non-small cell lung cancer in patients receiving antacids

BackgroundProton pump inhibitors (PPIs) are reported to decrease the efficacy of immune checkpoint inhibitors (ICIs), but there are few reports on the association between ICI efficacy and antacids other than PPIs, and simultaneous examination of the effects of antacids, corticosteroids, and non-steroidal anti-inflammatory drugs (NSAIDs) on ICI therapy. MethodsWe conducted a retrospective study of 381 patients with non-small cell lung cancer who received ICI therapy from January 1, 2016 to December 31, 2022. The primary endpoint was overall survival (OS) and the secondary endpoint was progression-free survival (PFS). Antacids included histamine type 2 receptor antagonists (H2RAs), PPIs, and potassium-competitive acid blockers (P-CABs). ResultsAntacids were administered to 218 patients, including 168 with PPIs, 37 with P-CABs, and 13 with H2RAs. Patients with antacids had worse median PFS and OS than those without antacids (PFS, 2.9 vs. 6.2 months; OS, 12.3 vs. 24.0 months), and those with PPIs, P-CABs, or H2RAs had similar results. However, there were no significant differences between patients with and without antacids when stratified by corticosteroid and NSAID use. Multivariate analyses showed that corticosteroids and NSAIDs administered for cancer-associated symptoms were related to poor prognosis, but antacids including PPIs, P-CABs, or H2RAs were not related. ConclusionsAntacids were not related to ICI efficacy when NSAIDs or corticosteroids were taken into consideration. This may be because the most frequent reason for administering NSAIDs and corticosteroids was cancer-associated symptoms, which are a poor prognostic factor, and most of the patients treated with these medications also received antacids.

Medical marijuana in the treatment of cancer-associated symptoms.

Previous cancer studies have indicated that medical marijuana addresses a significant unmet need, namely chronic pain treatment and conferring oncology supportive care. However, the clinical research evaluating medical marijuana is preliminary and requires further consideration. We conducted a PubMed search primarily comprising retrospective and prospective studies, systematic reviews, and randomized clinical trials (RCTs) from approximately 2020-2023. The search included specific terms that incorporated medical marijuana, cancer treatment, cancer-related symptoms, pain management, and side effects. A total of 40 studies were included in the review, many of which were either of acceptable or good quality. Select investigations indicated that medical marijuana was associated with decreased overall pain levels and improvements in nausea and vomiting. Alternatively, the results from RCTs have found that the benefits from a placebo were equivalent to medical marijuana in both the treatment of cancer-related pain and providing an opioid-sparing effect. Despite the potential cancer-related benefits derived from medical marijuana, the study design and results for many of the investigations on which the evidence is based, were neither uniform nor conducted via RCTs; hence, the efficacy and appropriateness of medical marijuana in treating cancer-related conditions remain indeterminate.

Quantifying Antibody-Dependent Cellular Cytotoxicity in a Tumor Spheroid Model: Application for Drug Discovery.

Monoclonal antibody-based immunotherapy targeting tumor antigens is now a mainstay of cancer treatment. One of the clinically relevant mechanisms of action of the antibodies is antibody-dependent cellular cytotoxicity (ADCC), where the antibody binds to the cancer cells and engages the cellular component of the immune system, e.g., natural killer (NK) cells, to kill the tumor cells. The effectiveness of these therapies could be improved by identifying adjuvant compounds that increase the sensitivity of the cancer cells or the potency of the immune cells. In addition, undiscovered drug interactions in cancer patients co-medicated for previous conditions or cancer-associated symptoms may determine the success of the antibody therapy; therefore, such unwanted drug interactions need to be eliminated. With these goals in mind, we created a cancer ADCC model and describe here a simple protocol to find ADCC-modulating drugs. Since 3D models such as cancer cell spheroids are superior to 2D cultures in predicting in vivo responses of tumors to anticancer therapies, spheroid co-cultures of EGFP-expressing HER2+ JIMT-1 breast cancer cells and the NK92.CD16 cell lines were set up and induced with Trastuzumab, a monoclonal antibody clinically approved against HER2-positive breast cancer. JIMT-1 spheroids were allowed to form in cell-repellent U-bottom 96-well plates. On day 3, NK cells and Trastuzumab were added. The spheroids were then stained with Annexin V-Alexa 647 to measure apoptotic cell death, which was quantitated in the peripheral zone of the spheroids with an automated microscope. The applicability of our assay to identify ADCC-modulating molecules is demonstrated by showing that Sunitinib, a receptor tyrosine kinase inhibitor approved by the FDA against metastatic cancer, almost completely abolishes ADCC. The generation of the spheroids and image acquisition and analysis pipelines are compatible with high-throughput screening for ADCC-modulating compounds in cancer cell spheroids.

Effects of glucocorticoid use on survival of advanced non-small-cell lung cancer patients treated with immune checkpoint inhibitors.

Lung cancer is the second most common cancer worldwide, with non-small-cell lung cancer (NSCLC) accounting for the majority of cases. Patients with NSCLC have achieved great survival benefits from immunotherapies targeting immune checkpoints. Glucocorticoids (GCs) are frequently used for palliation of cancer-associated symptoms, as supportive care for non-cancer-associated symptoms, and for management of immune-related adverse events (irAEs). The aim of this study was to clarify the safety and prognostic significance of glucocorticoid use in advanced patients with NSCLC treated with immune checkpoint inhibitors (ICIs). The study searched publications from PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine disc, Chinese National Knowledge Infrastructure, Wanfang Data, and Chinese Science and Technology Journal Database up to March 1st, 2022, and conducted a meta-analysis to assess the effects of glucocorticoid use on overall survival (OS) and progression-free survival (PFS) in NSCLC patients treated with ICIs through the available data. The study calculated the pooled hazard ratios (HRs) and 95% confidence intervals (CIs). This study included data from 25 literatures that were mainly retrospective, with 8713 patients included. Patients taking GCs had a higher risk for tumor progression and death compared with those not taking GCs (PFS: HR = 1.57, 95% CI: 1.33-1.86, P <0.001; OS: HR = 1.63, 95% CI: 1.41-1.88, P <0.001). GCs used for cancer-associated symptoms caused an obviously negative effect on both PFS and OS (PFS: HR = 1.74, 95% CI: 1.32-2.29, P <0.001; OS: HR = 1.76, 95% CI: 1.52-2.04, P <0.001). However, GCs used for irAEs management did not negatively affect prognosis (PFS: HR = 0.68, 95% CI: 0.46-1.00, P = 0.050; OS: HR = 0.53, 95% CI: 0.34-0.83, P = 0.005), and GCs used for non-cancer-associated indications had no effect on prognosis (PFS: HR = 0.92, 95%CI: 0.63-1.32, P = 0.640; OS: HR = 0.91, 95% CI: 0.59-1.41, P = 0.680). In advanced NSCLC patients treated with ICIs, the use of GCs for palliation of cancer-associated symptoms may result in a worse PFS and OS, indicating that they increase the risk of tumor progression and death. But, in NSCLC patients treated with ICIs, the use of GCs for the management of irAEs may be safe, and the use of GCs for the treatment of non-cancer-associated symptoms may not affect the ICIs' survival benefits. Therefore, it is necessary to be careful and evaluate indications rationally before administering GCs in individualized clinical management.

Out-of-pocket costs burden for cancer treatment toxicities and symptoms management in Italy: A prospective, multicenter pilot study.

12105 Background: Financial Toxicity (FT) refers to the financial burden and stress experienced by cancer patients as a result of the high costs associated with their treatment and care. This burden can significantly impact patients and families, affecting not only their financial well-being but also their physical and mental health. With the increasing cost of cancer care, FT has become a primary concern for those affected by the disease. Although there have been plenty of studies on the cost of cancer drugs and policy issues relating to curbing these increasing costs, studies on addressing FT in individual patients for drug-related toxicity and symptom management are still lacking. Methods: From January to October 2022, we conducted a cross-sectional, descriptive study to identify patient-administered drugs used to manage cancer treatment toxicities or cancer-associated symptoms. We recognize six common symptoms (anorexia/cachexia, fatigue, nausea and vomiting, pain, constipation, and diarrhea). All social and demographic data, including information on gender, age, performance status, education, and income, have been gathered and recorded. We collected information about the type of cancer disease and active treatment (on/off). Symptom assessment and financial distress were analyzed by administering the PERSONS and COST questionnaires, respectively, at the time of enrollment. Results: A total of 211 patients were enrolled and completed the questionnaires. 28/211 patients (13%) do not take any medications to control symptoms. Of the remaining 183 taking at least one prescription for managing these symptoms, 90% (165) pay for at least part of these drugs. Most frequently, patients assumed medicines for controlling pain (45%) and constipation (28%). Unlike all the other drug categories, these medicines correlate with financial distress (p &gt; 0.0001 and p &gt; 0.001). None of the following variables (age, type of tumor, and work situation) significantly interacted with COST and PERSONS at the univariate analyses. In contrast, a lower level of education significantly associates with the worst COST and PERSONS scores (p &gt; 0.0001). As expected, patients in palliative home care have a higher mean score for symptom burden than those without home care and, surprisingly, a higher financial distress score. Conclusions: Our results identify cancer pain and constipation as the most incident and challenging problems associated with cancer diagnosis and treatment. Moreover, they ultimately lead to a higher financial hardship due to patient self-prescribing and out-of-pocket purchases of over-the-counter drugs to control them. In our population, a lower education level is an independent risk factor for developing financial distress.

Enfortumab Vedotin in metastatic bladder cancer: a case report of durable clinical efficacy in a pretreated patient.

Metastatic urothelial bladder cancer is associated with high mortality rates. The advent of immunocheckpoint inhibitors (ICIs), with the approval of pembrolizumab in second line treatment, has changed the treatment landscape and improved clinical outcomes of patients. Until recently, subsequent lines of therapy have been limited to single-agents chemotherapy, poor efficacy and relevant toxicities. Recent studies in pretreated urothelial bladder cancer have led to the approval in clinical practice of enfortumab vedotin, demonstrating better clinical efficacy compared with the standard of care. Herein we report a case of a 57-year-old male patient with metastatic bladder cancer, who had unsatisfactory responses to first-line chemotherapy and subsequent second-line immunotherapy. Based on robust data of efficacy and safety from clinical trials, we treated the patient with enfortumab vedotin as third-line therapy. An initial adverse event, probably not strictly related to the drug, led to temporarily discontinuation of enfortumab vedotin and subsequent administration with a dose reduction. Despite this, the drug induced a first partial response on most of the metastatic sites and a complete response on lung and pelvic metastases was subsequently observed. Of note, responses were durable, with good tolerability and improvement in cancer-associated symptoms, such as pain.

Pemetrexed and Platinum Plus Pembrolizumab in Patients With Metastatic Nonsquamous NSCLC by Tumor Burden at Baseline: A Post Hoc Efficacy Analysis of KEYNOTE-189

IntroductionThe aim of this study was to evaluate the efficacy of pemetrexed and platinum plus pembrolizumab by baseline tumor burden. MethodsA total of 616 patients in the intention-to-treat population of the KEYNOTE-189 study were included in this analysis. Baseline tumor burden subgroups were identified on the basis of extent of distant metastasis (M1a versus M1b), median number (≤3 versus >3) of organ systems with lesions, or symptom severity score of patient-reported lung cancer-associated symptoms (≤median versus >median). Overall survival (OS), progression-free survival (PFS), and PFS-2 were evaluated by Kaplan-Meier and univariate Cox methods. Objective response rate was analyzed using logistic regression models, and duration of response was analyzed descriptively. Efficacy outcomes were also analyzed according to the programmed death-ligand 1 expression levels. ResultsOS and PFS were significantly improved with pemetrexed and platinum plus pembrolizumab in all baseline tumor burden subgroups (M1a stage: OS hazard ratio [HR] = 0.54, p = 0.0037; PFS HR = 0.48, p = 0.0001; M1b stage: OS HR = 0.58, p ≤ 0.0001; PFS HR = 0.51, p ≤ 0.0001; number of organ systems with lesion ≤ 3: OS HR = 0.49, p ≤ 0.0001 PFS HR = 0.41, p ≤ 0.0001; >3: OS HR = 0.67, p = 0.0068; PFS HR = 0.59, p = 0.0001; symptom severity score ≤ median: HR = 0.51, p ≤ 0.0001; PFS HR 0.49, p ≤ 0.0001; > median: OS HR = 0.60, p = 0.0003; PFS HR = 0.48, p ≤ 0.0001). PFS2 and objective response rate were also improved with pemetrexed and platinum plus pembrolizumab in all baseline tumor burden subgroups. Efficacy outcomes were generally consistent regardless of programmed death-ligand 1 expression levels. ConclusionsPemetrexed and platinum plus pembrolizumab were found to have relevant efficacy regardless of the extent of baseline tumor burden and the variables used to define it. These results further support pemetrexed and platinum plus pembrolizumab as the standard of care in the first-line treatment of metastatic nonsquamous NSCLC.

Early integration of palliative care into oncological care: a focus on patient-important outcomes.

Globally, cancer remains one of the leading causes of mortality. Palliative care is designed to meet a range of cancer patients' priority issues, including the management of pain and other cancer-associated symptoms. Routine palliative care envisages the provision of not just medical therapy, but also psychological support, social support and spiritual assistance. What constitutes the best model for palliative care remains a matter of debate. This review was undertaken with the aim to discuss different aspects of early integration of palliative care into oncological care, with a focus on patient-important outcomes. A comprehensive search of publications was conducted with a focus on integrative palliative care for incurable cancer patients. For this purpose, the following databases and search engines were used: Scopus, PubMed, Cochrane Library, Research Gate, Google Scholar, eLIBRARY and Cyberleninka. A comprehensive approach with early integration of different medical services appears to be the most promising. Integrative palliative care is best provided via specialised interdisciplinary teams, given that all members maintain systemic communications and regularly exchange information. This model ensures that timely and adequate interventions are provided to address the needs of patients. Further research is needed to pinpoint the most optimal strategies to deliver palliative care and make it as tailored to the patient's demands as possible.

Knowledge, attitudes and practices of cervical cancer screening among rural women in KwaZulu-Natal, South Africa.

Introductioncervical cancer continues to be a major cause of morbidity and mortality among women in the developing world. Despite the national cervical cancer screening programme, findings show low levels of knowledge and practices of cervical cancer screening among rural women in South Africa (SA). The purpose of this study was to determine the knowledge, attitudes and practices of cervical cancer screening among rural women in KwaZulu-Natal, SA.Methodsan observational cross-sectional study was performed. The study was conducted at three rural clinics. A systematic sampling technique was used to select 283 women, aged 18-65 years. Data were collected using a standardised structured self-administered questionnaire. Data were analysed using descriptive and analytic statistics.Resultsfindings showed a high level of awareness of cervical cancer (93.3%, n=264) and the Pap smear test (95.1%, n=269). Knowledge of cervical cancer-associated factors, symptoms, screening methods and treatment was poor (28.0%, n=79). An overwhelming majority (81.8%, n=231) displayed a positive attitude towards cervical cancer screening. The practice of cervical cancer screening was fairly good (66.8%, n=189). The results showed that socio-demographics were not statistically significantly associated with knowledge of cervical cancer and cervical cancer screening.Conclusiondespite the inadequate knowledge of women, attitudes towards cervical cancer and screening were generally positive. Health care practitioners are encouraged to focus not only on creating awareness but also on improving knowledge so as women will not only undergo screening but appreciate the importance of cervical cancer screening.

In the weeds: a retrospective study of patient interest in and experience with cannabis at a cancer center.

BackgroundCannabis products, including the cannabinoids CBD and THC, are rising in popularity and increasingly used for medical purposes. While there is some evidence that cannabinoids improve cancer-associated symptoms, understanding regarding appropriate use remains incomplete.PurposeTo describe patient experiences with medical cannabis with focus on use contexts and patients’ reported benefits and harms.MethodsA standardized intake form was implemented in a dedicated medical cannabis clinic at an NCI-designated cancer center; data from this form was abstracted for all initial visits from October 2019 to October 2020. We report descriptive statistics, chi-square analysis, and multivariate logistic regression.ResultsAmong 163 unique new patients, cannabis therapy was commonly sought for sleep, pain, anxiety, and appetite. Twenty-nine percent expressed interest for cancer treatment; 40% and 46% reported past use of CBD and THC, respectively, for medical purposes. Among past CBD users, the most commonly reported benefits were less pain (21%) or anxiety (17%) and improvement in sleep (15%); 92% reported no side effects. Among those with past THC use, reported benefits included improvement in appetite (40%), sleep (32%), nausea (28%), and pain (17%); side effects included feeling “high.” Seeking cannabis for anti-neoplastic effects was associated with receipt of active cancer treatment in both univariate and multivariate analysis.ConclusionCancer patients seek medical cannabis to address a wide variety of concerns despite insufficient evidence of benefits and harms. As more states move to legalize medical and recreational cannabis, cancer care providers must remain aware of emerging data and develop knowledge and skills to counsel their patients about its use.Supplementary InformationThe online version contains supplementary material available at 10.1007/s00520-022-07170-8.

Finding the Lowest-Cost Pharmacy for Cancer Supportive Care Medications: Not So Easy.

To decrease the financial burden on people with cancer, clinicians and patients increasingly use medication price comparison websites to seek pharmacies where medications may be cheaper. Shopping around at different pharmacies can add additional time and logistic burden to patients and care partners. We sought to determine whether a single pharmacy consistently offered the lowest price for symptom control medications. We compiled medications/formulations used to manage two common cancer-associated symptoms: nausea/vomiting and anorexia/cachexia. We extracted discounted, lowest price with coupon prices for a typical fill of these medications at nine pharmacies in Minneapolis, MN, using GoodRx. We compared prices across formulations and pharmacies to assess whether a pharmacy consistently offered the lowest price. We included 24 formulations for nausea/vomiting (14 generic and 10 brand-name) and 19 for anorexia/cachexia (12 generic and seven brand-name). Prices for brand-name formulations were similar across pharmacies, but prices of generic formulations varied widely across pharmacies. For example, the prices of a seven-unit fill of generic 5-mg olanzapine tablets ranged from $4 to $57 US dollars. No single pharmacy consistently offered the lowest price across the formulations studied. For example, for the 12 generic formulations for anorexia/cachexia, one pharmacy had the highest price for four formulations and the lowest price for two others. In this study of discounted medication prices, we found that no single pharmacy in an urban zip code consistently offered the lowest price for medications used to manage two common cancer-associated symptoms. Well-intentioned efforts to pursue the cheapest source of each medication by visiting multiple pharmacies may add extra time and logistic toxicity to patients and care partners. This approach can increase redundant scripts and expose patients to medication-related adverse events.

Diet and Health-related Quality of Life Among Men on Active Surveillance for Early-stage Prostate Cancer: The Men’s Eating and Living Study (Cancer and Leukemia Group 70807 [Alliance

BackgroundHealth-related quality of life (HRQoL) among patients with localized prostate cancer (PC) on active surveillance (AS) and whether it may be improved through lifestyle-focused interventions remain underdefined. ObjectiveTo assess longitudinal changes in HRQoL in patients who received and those who did not receive a behavioral intervention that increased vegetable intake. Design, setting, and participantsA secondary analysis of participants in the Men’s Eating and Living (MEAL) study (Cancer and Leukemia Group 70807 [Alliance]), a randomized trial of vegetable consumption in patients on AS, was conducted. Outcome measurements and statistical analysisPatient-reported outcomes (PROs) included the Memorial Anxiety Scale for Prostate Cancer (MAX-PC), the Expanded Prostate Cancer Index Composite 26 (EPIC-26), and the Functional Assessment of Cancer Therapy Scale—Prostate (FACT-P). Areas under the curves (AUCs) were used to summarize serial HRQoL. Results and limitationsPROs were completed in 87% (n = 387) of the intention-to-collect population. Baseline characteristics of patients completing HRQoL measures did not differ significantly from the entire study population or between groups. Baseline scores were high for all PROs and remained stable over 24 mo, with no significant differences from baseline at any time point. In adjusted analyses, there were no significant differences in summary AUC measures comparing control with intervention for the total MAX-PC score (p = 0.173); EPIC-26 domains of urinary incontinence (p = 0.210), urinary obstruction (p = 0.062), bowel health (p = 0.607), sexual health (p = 0.398), and vitality (p = 0.363); and total FACT-P scores (p = 0.471). ConclusionsAmong men with localized PC on AS enrolled in a randomized trial, HRQoL was high across multiple domains at baseline, remained high during follow-up, and did not change in response to a behavioral intervention that increased vegetable intake. Patient summaryPatients with localized prostate cancer enrolled on active surveillance experience minimal cancer-associated anxiety, suffer low levels of cancer-associated symptoms, and perceive high physical and emotional well-being.

Multi-targeted therapy of cancer by omega-3 fatty acids-an update

Low in dietary ω3 polyunsaturated fatty acid (PUFA) consumption has been associated with increased incidence of cancers. Many basic and clinical studies have been conducted over the last several decades. We previously reviewed multi-targeted therapy of cancer by omega-3 fatty acids in 2008, and since hundreds of new clinical trials are being conducted to validate the effectiveness of ω3 PUFA in cancer therapy. Because of the availability of such large amount of clinical trial data, in this update we summarize clinical data, sort out trials that show promising results, and discuss potential mechanism(s) responsible for the clinical outcomes. It appears that ω3 PUFA mainly affects cancer-associated symptoms, namely cachexia, inflammation, neuropathy, post operative complications and quality of life. Mechanisms responsible for these effects are possible regulation of skeletal muscle protein turnover, inflammatory response and neuron cell survive by ω3 PUFA.

Analysis of Patient Reported Outcomes for Stage IV Non-Small Cell Lung Cancer Patients in Ontario

Stage IV non-small cell lung cancer (NSCLC) is associated with substantial disease and treatment-related morbidity. In Ontario, Canada, patient reported outcomes (PRO) evaluation through Edmonton Symptom Assessment System (ESAS) has been integrated into clinical workflow since 2007. ESAS elicits patients' self-reported severity of common cancer-associated symptoms at clinical encounters. ESAS domains are anxiety, depression, drowsiness, appetite, nausea, pain, shortness of breath, tiredness, and well-being. This province-wide study investigated moderate-to-severe symptom burden in this population.ESAS collected from stage IV NSCLC patients diagnosed between 2007-2018 linked to Ontario provincial healthcare system database were studied. ESAS acquired within 12 months following diagnosis were analyzed and the proportion reporting moderate-to-severe scores (ESAS ≥4) in each domain was calculated and plotted over time. Potential covariates of moderate-to-severe scores: lung cancer treatments, age, sex, Elixhauser comorbidity index, immigration status, income quintiles, and time since diagnosis were analyzed using multivariable Poisson regression models with robust error variance.Of 22,799 patients, 13,289 (58.3%) completed ESAS (84,373 assessments) in the year following diagnosis. Patients with older age, high comorbidity, and not receiving active cancer therapy had lower ESAS completion. Almost all patients (94.4%) reported at least 1 moderate-to-severe symptoms. Most prevalent were tiredness (84.1%), low wellbeing (80.7%), low appetite (71.7%), and shortness of breath (67.8%). Monthly peaks and nadirs of these symptoms were: 67.6% (month 1) and 47.0% (month 12) for tiredness; 64.6% (month 1) and 43.3% (month 10) for lack of wellbeing; 50.5% (month 1) and 33.1%. All symptoms severity peaked at 1 or 2 months after diagnosis and demonstrated downwards trajectories in the subsequent months. On multivariable analyses, moderate-to-severe scores in all ESAS domains were associated with radiotherapy within 2 weeks prior, while drowsiness, low appetite and wellbeing, nausea, and tiredness were associated with systemic therapy within 2 weeks prior. Comorbidity, low income, non-immigrants, and urban residency were also associated with moderate-to-severe symptoms.This province-wide PRO analysis showed moderate-to-severe symptoms were highly prevalent and persistent among metastatic NSCLC patients, underscoring the need to address supportive measures in this population especially around treatments. In-person PRO completions were lower among patients who are older, highly comorbid, and not receiving active treatment, arguably more vulnerable patients. Implementation of virtual PRO may lower barrier to care, allowing timely identification of symptoms that may be amenable to intervention in these patients.

Financial Burden of Drugs Prescribed for Cancer-Associated Symptoms.

PURPOSE:The financial toxicity of anticancer drugs is well-documented, but little is known about the costs of drugs used to manage cancer-associated symptoms.METHODS:We reviewed relevant guidelines and compiled drugs used to manage seven cancer-associated symptoms (anorexia and cachexia, chemotherapy-induced peripheral neuropathy, constipation, diarrhea, exocrine pancreatic insufficiency, cancer-associated fatigue, and chemotherapy-induced nausea and vomiting). Using GoodRx website, we identified the retail price (cash price at retail pharmacies) and lowest price (discounted, best-case scenario of out-of-pocket costs) for patients without insurance for each drug or formulation for a typical fill. We describe lowest prices here.RESULTS:For anorexia and cachexia, costs ranged from $5 US dollars (USD; generic olanzapine or mirtazapine tablets) to $1,156 USD (brand-name dronabinol solution) and varied widely by formulation of the same drug or dosage: for olanzapine 5 mg, $5 USD (generic tablet) to $239 USD (brand-name orally disintegrating tablet). For chemotherapy-induced peripheral neuropathy, costs of duloxetine varied from $12 USD (generic) to $529 USD (brand-name). For constipation, the cost of sennosides or polyethylene glycol was <$15 USD, whereas newer agents such as methylnaltrexone were expensive ($1,001 USD). For diarrhea, the cost of generic loperamide or diphenoxylate-atropine tablets was <$15 USD. For exocrine pancreatic insufficiency, only brand-name formulations were available, range of cost, $1,072 USD-$1,514 USD. For cancer-associated fatigue, the cost of generic dexamethasone or dexmethylphenidate was <$15 USD, whereas brand-name modafinil was more costly ($1,284 USD). For a 4-drug nausea and vomiting prophylaxis regimen, costs ranged from $181 USD to $1,430 USD.CONCLUSION:We highlight the high costs of many symptom control drugs and the wide variation in the costs of these drugs. These findings can guide patient-clinician discussions about cost-effectively managing symptoms, while promoting the use of less expensive formulations when possible.

Neuroimmunology of cancer and associated symptomology.

Evolutionarily, the nervous system and immune cells have evolved to communicate with each other to control inflammation and host responses against injury. Recent findings in neuroimmune communication demonstrate that these mechanisms extend to cancer initiation and progression. Lymphoid structures and tumors, which are often associated with inflammatory infiltrate, are highly innervated by multiple nerve types (e.g. sympathetic, parasympathetic, sensory). Recent preclinical and clinical studies demonstrate that targeting the nervous system could be a therapeutic strategy to promote antitumor immunity while simultaneously reducing cancer-associated neurological symptoms, such as chronic pain, fatigue and cognitive impairment. Sympathetic nerve activity is associated with physiological or psychological stress, which can be induced by tumor development and cancer diagnosis. Targeting the stress response through suppression of sympathetic activity or activation of parasympathetic activity has been shown to drive activation of effector T cells and inhibition of myeloid-derived suppressor cells within the tumor. In addition, there is emerging evidence that sensory nerves may regulate tumor growth and metastasis by promoting or inhibiting immunosuppression in a tumor-type specific manner. Because neural effects are often tumor-type specific, further study is required to optimize clinical therapeutic strategies. This review examines the emerging evidence that neuroimmune communication can regulate antitumor immunity as well as contribute to development of cancer-related neurological symptoms.

Effect of Self-Care Guidelines on Symptoms Burden for Patients with Lung Cancer Undergoing Chemotherapy

Context: Lung cancer is common cancer worldwide. Because of the high-symptoms burden and severe morbidity, effective symptoms management requires comprehensive self-care strategies.&#x0D; Aim: This study was aimed to assess the effect of self-care guidelines on symptoms burden for patients with lung cancer undergoing chemotherapy.&#x0D; Methods: This study was conducted at the outpatient clinics in Radiation Oncology and Nuclear Medicine Center, affiliated to Ain Shams University. A quasi-experimental (pre/posttest) design was employed on a purposive sample of 50 adult patients were recruited for this study. The data were collected through a structured interview questionnaire to assess the patients’ socio-demographic characteristics, medical health profile, and knowledge about lung cancer. Lung Cancer and Chemotherapy Associated Symptoms Self-care Practices’ Assessment Questionnaire and M. D. Anderson Symptom Inventory-Lung Cancer (MDASI-LC) were also used.&#x0D; Results: The present study revealed that 36% of the patients had a satisfactory level of knowledge pre-implementation of self-care guidelines, which improved significantly for 48% of the patients post-implementation at p 0.007. 26.3% of them exhibit a satisfactory level of self-care practice pre-implementation of self-care guidelines that improved significantly (57.9%) post-implementation at p 0.001. Also, lung cancer symptom burdens and symptoms' influence on patients' lives were significantly improved after the implementation compared with preintervention level at p 0.001. A non-significant difference between pre and post-implementation of self-care guidelines regarding symptoms interference with patients' life was revealed at p 0.801. There were statistically negative correlations between patients' total symptom severity and self-care practice pre- and post-self-care guidelines implementation. &#x0D; Conclusion: self-care guidelines have a statistically significant positive effect on decreasing the severity of lung cancer symptoms. While chemotherapy-associated symptoms were slightly improved, there were no significant differences between pre and post-self-care guidelines implementation regarding symptoms interference with patients’ life. Health education programs about the disease and its management should be provided for lung cancer patients.

Symptom Burden of Patients with Advanced Pancreas Cancer (APC): A Provincial Cancer Institute Observational Study.

Patients with advanced pancreatic cancer (APC) experience many disease-related symptoms. ESAS-r measures the severity of 9 symptom domains and has been validated for use in the ambulatory oncology setting. We aimed to describe symptom burden at baseline for patients with APC treated with modern chemotherapy (CT), and to determine whether symptom burden at baseline is prognostic. Patients diagnosed with APC between 2012–2016, treated with ≥1 cycle of CT, who completed ≥1 ESAS-r were identified. Descriptive statistics were used to report symptom burden and common moderate-to-severe symptoms. A joint model was used to describe the trajectory of ESAS-r during follow-up while controlling for death. Multivariable Cox regression was used to identify independent predictors of death. Of 123 patients identified, the median age was 65 and 61% had metastatic disease. The median baseline ESAS-r total symptom distress score (TSDS) was 24. A total of 86% of patients had at least one symptom score of ≥4 at baseline, with the most common being: fatigue, nausea, anxiety, and shortness of breath. Median overall survival was 10.2 months. Baseline TSDS was not predictive for worse survival in the era of modern CT. Patients with APC have a high burden of cancer-associated symptoms and a high prevalence of moderate-to-severe symptoms. Early intervention has the potential to improve quality of life in this group of patients and should be investigated.

Province-wide analysis of patient reported outcomes for stage IV non-small cell lung cancer.

12092 Background: Stage IV NSCLC patients have significant disease and treatment-related morbidity. In Ontario, Canada, cancer patients complete Edmonton Symptom Assessment System (ESAS) questionnaires, a tool that elicits patients’ self-reported severity of common cancer-associated symptoms at clinical encounters. ESAS domains are: anxiety, depression, drowsiness, appetite, nausea, pain, shortness of breath, tiredness and well-being. The purpose of this study is to examine moderate-to-severe symptom burden in the 12 months following a diagnosis of stage IV NSCLC. Methods: Using administrative databases and unique encoded identifiers, stage IV NSCLC diagnosed between January 2007 and September 2018 were evaluated for symptom screening with ESAS in the 12 months following diagnosis. Proportion of patients reporting moderate-to-severe score (i.e. ESAS ≥4) in each domain within 12 months were calculated. Patients reporting moderate-to-severe within the different ESAS domains of were plotted over time. Multivariable (MV) Poisson regression models with potential covariates such as age, sex, Elixhauser comorbidity index, income quintiles, and lung cancer treatments received were constructed to identify factors associated with moderate-to-severe symptoms. Results: Of 22,799 stage IV NSCLC patients, 13,289 (58.3%) had completed ESAS (84,373 unique assessments) in the year following diagnosis. Patients with older age, high comorbidity, and not receiving active cancer therapy were less likely to complete ESAS. Most (94.4%) reported at least 1 moderate-to-severe score. Most prevalent moderate-to-severe ESAS symptoms within 12 months after diagnosis were tiredness (84.1%), lack of wellbeing (80.7%), low appetite (71.7%), and shortness of breath (67.8%); nausea was the least prevalent (34.6%). Most symptoms peaked at diagnosis and persisted in the year after diagnosis. On adjusted MV analyses, patients with high comorbidity, low income, and urban residency were associated with increased moderate-to-severe symptoms. Moderate-to-severe scores in all ESAS symptoms were associated with delivery of radiotherapy within 2 weeks prior, while moderate-to-severe nausea, drowsiness, tiredness, low appetite, and lack of wellbeing were associated with delivery of systemic therapy within preceding 2 weeks. Conclusions: In this population-based analysis of stage IV NSCLC PROs in the year following diagnosis, moderate-to-severe symptoms were highly prevalent and persistently high, underscoring the need to address supportive requirements in this at-risk population.
