RESUMO

Intermittent fasting is a dietary intervention that is increasingly being tested for positive outcomes in patients receiving cancer treatment. In this review, we examine the impact of intermittent fasting on symptoms, toxicities, and quality of life in patients undergoing cancer therapy and highlight unmet investigative areas to prompt future research. While current evidence is preliminary and conclusions mixed, some promising clinical studies suggest that intermittent fasting interventions may improve fatigue and reduce gastrointestinal toxicities in certain patients with cancer. Emerging clinical evidence also demonstrates that intermittent fasting may reduce off-target DNA damage, and induce favorable cellular-level immune remodeling. Furthermore, intermittent fasting has the potential to lower hyperglycemia and the ratio of fat to lean body mass, which may benefit patients at risk of hyperglycemia and weight-related adverse effects of some common pharmacological cancer treatments. Larger controlled studies are necessary to evaluate intermittent fasting in relation to these endpoints and determine the effectiveness of intermittent fasting as an adjunct intervention during cancer care. Future cancer trials should evaluate intermittent fasting diets in the context of multimodal diet, exercise, and nutrition strategies, and also evaluate the impact of intermittent fasting on other important areas such as the circadian system and the gut microbiome.

RESUMO

Patients with rare solid tumors treated on early phase trials experience toxicities from their tumors and treatments. However, limited data exist to describe the detailed symptom burden suffered by these patients, particularly those with rare solid tumors treated with immunotherapy. We performed a prospective longitudinal study to capture patient-reported symptom burden. Patients completed the validated MD Anderson Symptom Inventory (MDASI)-Immunotherapy with 20 symptoms including 7 immunotherapy-specific items and 6 interference items at baseline and weekly thereafter for up to 9 weeks. Symptoms and interference were rated on 0-10 scales (0 = none or no interference, 10 = worst imaginable or complete interference). Group-based trajectory modelling determined higher and lower symptom groups. A total of 336 MDASI questionnaires were completed by 53 patients (mean age 55.4y, 53% male) with advanced rare cancers receiving pembrolizumab in a Phase II clinical trial. Symptoms reported as most severe over the course of the treatment over 9 weeks were fatigue [mean (M) = 3.8, SD = 2.3], pain (M = 3.7, SD = 2.9), disturbed sleep (M = 2.7, SD = 2.3), drowsiness (M = 2.6, SD = 2.0) and lack of appetite (M = 2.5, SD = 2.1). Pain in the abdomen (M = 2.2, SD = 2.4), rash (M = 1.1, SD = 1.8) and diarrhea (M = 0.9, SD = 1.5) were less severe. Interference with walking was rated the highest (M = 3.4, SD = 2.8) and relations with others was rated the lowest (M = 2.1, SD = 2.6). Using a composite score based on the five most severe symptoms (fatigue, pain, lack of appetite, feeling drowsy and sleep disturbance), 43% were classified into the high symptom burden group. Using a score based on immunotherapy-specific symptoms (e.g., rash, diarrhea) 33% of patients were included in the high symptom group. Symptom burden stayed relatively stable in the high- and low-symptom burden patient groups from baseline through 9 weeks. Some patients with rare malignancies experienced high symptom burden even at baseline. In patients with rare cancers, symptom trajectories stayed relatively stable over nine weeks of treatment with pembrolizumab.Trial registration: ClinicalTrials.gov identifier: NCT02721732.

RESUMO

The general nutritional status of cancer patients could be a central determinant of cancer treatment-related toxicity and an indicator of cancer symptoms such as cancer-related cachexia and weight loss. This narrative scientific review covers the impact of dietary patterns (for example, Mediterranean diet, short-term fasting, ketogenic diet), dietary components (for example, fruits and vegetables, fish oils, turmeric/curcumin, dietary fiber, phytochemicals, vitamin/mineral dietary supplements), and the gut microbiota on symptoms, toxicities, and adverse events associated with cancer treatment. Although several studies have produced controversial or inconclusive results, some promising preclinical studies and initial clinical trials suggest that dietary interventions may alleviate certain cancer treatment-related symptoms and toxicities. Possible mechanisms by which dietary components may influence symptomatic and non-symptomatic toxicities during cancer treatment include through impacting inflammation, oxidative stress, muscle mass, cardiac health and regulating the gut microbiome. Current ongoing studies will continue to shed light on whether specific dietary interventions, with a special emphasis on the gut microbiota, are an effective method to improve cancer treatment outcomes. Future studies should examine the synergistic effects of combining different nutritional interventions and establish diet-related guidelines for cancer treatment.

RESUMO

Adoptive cell therapy (ACT) has shown promise in hematologic and solid tumors. While data supports immunogenicity of gynecologic cancers, the benefit of ACT is not yet clear. To address this question, we performed a comprehensive systematic review and meta-analysis. Eligible studies included those reporting oncologic response or toxicity data in at least one patient with any gynecologic cancer treated with ACT. Chi-square test and multivariable logistic regression were performed to identify predictors of response. We retrieved 281 articles, and 28 studies met our inclusion criteria. These comprised of 401 patients including 238 patients with gynecologic cancers (61.8% ovarian, 34.0% cervical, 2.9% endometrial, and 1.2% other). In patients with gynecologic cancers, response rates to ACT were 8.1% complete response, 18.2% partial response, and 31.4% stable disease, for an objective response rate (ORR) of 26.3%, disease control rate (DCR) of 57.6%, and median response duration of 5.5 months. Patients in studies reporting ≤1 median line of prior therapy had a higher ORR (52.9% vs. 22.6% for >1, p < 0.001), although DCR in the >1 group was still 53.2%. ORRs by ACT type were tumor infiltrating lymphocytes (TIL) 41.4%, natural killer cells 26.7%, peripheral autologous T-cells 18.4%, T-cell receptor-modified T-cells 15.4%, and chimeric antigen receptor T-cells 9.5% (p = 0.001). ORR was significantly improved with inclusion of lymphodepletion (34.8% vs. 15.4% without, p = 0.001). On multivariable analysis controlling for cancer type and lymphodepletion, TIL therapy was predictive of objective response (odds ratio 2.6, p = 0.011). The rate of grade 3 or 4 toxicity was 46.0%. All grade adverse events included fever, hypotension, dyspnea, confusion, hematologic changes, nausea/vomiting, fatigue, and diarrhea. In conclusion, ACT is a promising treatment modality in gynecologic cancer. We observed a particular benefit of TIL therapy and suggest inclusion of lymphodepletion in future trials.

RESUMO

PURPOSE: Cancer-associated cachexia is a common condition in patients with advanced cancer, and is associated with extreme and involuntary weight loss and irreversible muscle wasting. Despite its high morbidity and mortality, there is no known treatment to reverse its effects. Thus, there is increasing interest in whether diet and exercise can assist in the minimization of cancer-associated cachexia. METHODS: We reviewed the literature on the impact of dietary patterns, dietary components, and exercise on the progress and severity of cancer cachexia. RESULTS: Although most studies have produced inconclusive or controversial findings, some promising studies using animal models and early human clinical trials suggest that dietary and physical therapy interventions may alleviate cancer-associated cachexia. Moreover, many studies suggest that controlling diet and exercise nevertheless improved the quality of life (QoL) for cancer patients with cachexia. CONCLUSION: Ongoing studies will continue to examine whether different forms of multimodal therapy-combinations of cancer treatment, dietary regimens, anti-inflammatory therapy, and physical therapy-are effective methods to improve outcomes in advanced cancer patients with cachexia. Moreover, future studies should examine the effects of such interventions on long-term QoL and establish nutritional guidelines for the management of cancer-associated cachexia.

RESUMO

BACKGROUND: Clinical trials are an important therapeutic option for patients with cancer. Although financial burden in cancer treatment is well documented, the financial burden associated with clinical trials is not well understood. PATIENTS AND METHODS: We conducted a survey regarding economic burden and financial toxicity in patients with cancer enrolled in phase I clinical trials for >1 month. Financial toxicity score was assessed using the Comprehensive Score for Financial Toxicity survey. Patients also reported monthly out-of-pocket (OOP) costs. RESULTS: Two hundred and thirteen patients completed the survey (72% non-Hispanic White; 45% with annual income ≤$60,000; 50% lived >300 miles from the clinic; 37% required air travel). Forty-eight percent of patients had monthly OOP costs of at least $1,000. Fifty-five percent and 64% of patients reported unanticipated medical and nonmedical expenses, respectively. Worse financial toxicity was associated with yearly household income <$60,000 (odds ratio [OR]: 2.7; p = .008), having unanticipated medical costs (OR: 3.2; p = .024), and living >100 miles away from the clinical trial hospital (OR: 2.3; p = .043). Non-White or Hispanic patients (OR: 2.5; p = .011) and patients who were unemployed or not working outside the home (OR: 2.5; p = .016) were more likely to report high unanticipated medical costs. CONCLUSION: Among patients with cancer participating in clinical trials, economic burden is high, and most of patients' OOP costs were nonmedical costs. Financial toxicity is disproportionally higher in patients with lower income and those who travel farther, and unexpected medical costs were more common among non-White or Hispanic patients. OOP costs can be substantial and are often unexpected for patients. IMPLICATIONS FOR PRACTICE: The financial burden of cancer treatment is well documented, but there are limited data regarding the financial burden associated with cancer clinical trials. This study surveyed 213 patients enrolled in early-phase clinical trials. Monthly out-of-pocket costs were at least $1000 for nearly half of patients. Worse financial toxicity was associated with income <$60,000 and living farther away from the hospital. Racial/ethnic minorities had higher rates of unanticipated medical costs. These data help to quantify the high financial burden for patients and may reveal a cause of disparities in clinical trial enrollment for underrepresented populations.

RESUMO

INTRODUCTION: Immunotherapies have revolutionized the treatment of various cancers, but little is known about their symptomatic toxicity. Assessing these symptoms is best accomplished by asking the patients themselves. However, such reports are subjective and may face challenges as bonafide scientific data. Demonstrating the validity of symptom assessment tools, mainly through the reduction of measurement errors, has the potential to improve patient care if these tools are widely adopted. To that end, we present herein the psychometric properties of the Immunotherapy for Early-Phase Trials module of the MD Anderson Symptom Inventory (MDASI-Immunotherapy EPT) in patients receiving various immunotherapies in early phase trials at a major cancer center. METHODS: One hundred forty-five patients completed the inventory at baseline, with 85 of them also doing so after 9 weeks of treatment. The mean (±SD) age of the patients was 57.0±12.9 years. Also, 56% of the patients were women, 79% identified as white, and 49% had at least some college education. RESULTS: The internal consistency reliability of the MDASI-Immunotherapy EPT was excellent, as the Cronbach's alphas for all of its subscales were at least 0.88 (range 0.88-0.95). Known-group validity based on Eastern Cooperative Oncology Group performance status groupings was excellent at 9 weeks after the start of an immunotherapy trial for the MDASI-Immunotherapy EPT severity (effect size, 0.96) and interference (effect size, 0.82) subscales. We found substantial changes in the symptom items difficulty remembering (effect size, -0.85), fever and/or chills (effect size, -0.63), disturbed sleep (effect size, -0.52), diarrhea (effect size, -0.42), and swelling of hands, legs, or feet (effect size, -0.39). CONCLUSIONS: In conclusion, the MDASI-Immunotherapy EPT is a valid, reliable, and sensitive tool for measuring symptomatic toxicity.

RESUMO

BACKGROUND: Our objective was to determine the correlation between preclinical toxicity found in animal models (mouse, rat, dog and monkey) and clinical toxicity reported in patients participating in Phase 1 oncology clinical trials. METHODS: We obtained from two major early-Phase clinical trial centres, preclinical toxicities from investigational brochures and clinical toxicities from published Phase 1 trials for 108 drugs, including small molecules, biologics and conjugates. Toxicities were categorised according to Common Terminology Criteria for Adverse Events version 4.0. Human toxicities were also categorised based on their reported clinical grade (severity). Positive predictive values (PPV) and negative predictive values (NPV) were calculated to determine the probability that clinical studies would/would not show a particular toxicity category given that it was seen in preclinical toxicology analysis. Statistical analyses also included kappa statistics, and Matthews (MCC) and Spearman correlation coefficients. RESULTS: Overall, animal toxicity did not show strong correlation with human toxicity, with a median PPV of 0.65 and NPV of 0.50. Similar results were obtained based on kappa statistics and MCC. CONCLUSIONS: There is an urgent need to assess more novel approaches to the type and conduct of preclinical toxicity studies in an effort to provide better predictive value for human investigation.

RESUMO

Increasing numbers of oncology therapies are being approved based on early-phase single-arm studies. Yet, little is known regarding the use of patient-reported outcomes in single-arm oncology trials testing novel therapies. We examined patient-reported symptom severity and symptom interference with activity- (WAW: work, general activity, walking) and mood-(REM: relations with others, enjoyment of life, mood) related functioning, and their association with factors known to influence symptom severity reporting, in early-phase clinical trials clinic patients. Patients completed the validated MD Anderson Symptom Inventory, containing 13 severity items and six interference items, each rated on a 0-10 scale (higher scores = worse symptom severity/interference). Performance status (ECOG-PS) and age were ascertained. Multiple linear regression was performed. In 248 phase I patients (51% female, 90% ECOG 0-1, and 74% ≤65 years), 67% of patients had ≥seven concurrent symptoms of any severity level, and 51% of patients described ≥three concurrent symptoms as moderate-to-severe (severity rating ≥ 5). Composite symptom severity, WAW and REM were worse in patients with ECOG-PS ≥ 2 vs. 0-1, and worse in patients with ECOG-PS = 1 than in patients with ECOG-PS = 0. Compared with patients over 65y, adolescent and young adult (AYA) patients (18y-39y) and patients aged 40y to 65y had worse composite symptom severity. As expected, being employed full-time/retired was associated with better symptom profiles in phaseI patients. The variation of symptom burden by performance status and age suggest that these factors need to be considered in the design of early-phase trials, particularly if patient-reported symptoms are used as primary/secondary/exploratory endpoints.

RESUMO

Attribution of adverse events (AEs) is critical to oncology drug development and the regulatory process. However, processes for determining the causality of AEs are often sub-optimal, unreliable, and inefficient. Thus, we conducted a toxicity-attribution workshop in Silver Springs MD to develop guidance for improving attribution of AEs in oncology clinical trials. Attribution stakeholder experts from regulatory agencies, sponsors and contract research organizations, clinical trial principal investigators, pre-clinical translational scientists, and research staff involved in capturing attribution information participated. We also included patients treated in oncology clinical trials and academic researchers with expertise in attribution. We identified numerous challenges with AE attribution, including the non-informative nature of and burdens associated with the 5-tier system of attribution, increased complexity of trial logistics, costs and time associated with AE attribution data collection, lack of training in attribution for early-career investigators, insufficient baseline assessments, and lack of consistency in the reporting of treatment-related and treatment-emergent AEs in publications and clinical scientific reports. We developed recommendations to improve attribution: we propose transitioning from the present 5-tier system to a 2-3 tier system for attribution, more complete baseline information on patients' clinical status at trial entry, and mechanisms for more rapid sharing of AE information during trials. Oncology societies should develop recommendations and training in attribution of toxicities. We call for further harmonization and synchronization of recommendations regarding causality safety reporting between FDA, EMA and other regulatory agencies. Finally, we suggest that journals maintain or develop standardized requirements for reporting attribution in oncology clinical trials.

RESUMO

BACKGROUND: The role of cancer-related internet use on the patient-physician relationship has not been adequately explored among patients who are cancer-related internet users (CIUs) in early-phase clinical trial clinics. OBJECTIVE: We examined the association between cancer-related internet use and the patient-physician relationship and decision making among CIUs in an early drug development clinic. METHODS: Of 291 Phase I clinic patients who completed a questionnaire on internet use, 179 were CIUs. Generations were defined by the year of patient's birth: "millennials" (after 1990) and "Generation X/Y" (1965-1990) grouped as "Millennials or Generation X/Y"; "Baby Boomers" (1946-1964); and "Greatest or Silent Generation" (1945 and earlier). Statistical analyses included the Wilcoxon matched-pairs signed-rank test and the Mann-Whitney U test. RESULTS: CIUs were 52% (94/179) female, 44% (78/179) were older than 60 years, and 60% (108/179) had household incomes exceeding US $60,000. The sources of information on cancer and clinical trials included physicians (171/179, 96%), the internet (159/179, 89%), and other clinical trial personnel (121/179, 68%). For the overall sample and each generation, the median values for trust in referring and Phase I clinical trial physicians among early drug development clinic CIUs were 5 on a 0-5 scale, with 5 indicating "complete trust." CIUs' trust in their referring (5) and phase 1 (5) physicians was higher than CIUs' trust in Web-based cancer-related information (3; P<.001 for both). CIUs who reported visiting the National Cancer Institute (NCI) website, NCI.org, to learn about cancer reported higher levels of trust in Web-based cancer-related information than CIUs who did not use the NCI website (P=.02). Approximately half of CIUs discussed internet information with their doctor. Only 14% (23/165) of CIUs had asked their physician to recommend cancer-related websites, and 24% (35/144) of CIUs reported at least occasional conflict between their physician's advice and Web-based information. CONCLUSIONS: Despite the plethora of websites related to cancer and cancer clinical trials, patients in early-phase clinical trial settings trust their physicians more than Web-based information. Cancer-related organizations should provide regularly updated links to trustworthy websites with cancer and clinical trial information for patients and providers and educate providers on reliable cancer websites so that they can better direct their patients to appropriate internet content.

RESUMO

PURPOSE: We examined patterns, correlates, and the impact of cancer-related Internet use among patients with advanced cancer in a phase I clinical trials clinic for molecularly targeted oncologic agents. METHODS: An anonymous questionnaire on Internet use for cancer-related purposes that incorporated input from phase I clinical trial oncologists and patients was self-administered by patients age ≥ 18 years in a phase I clinic. Multivariable modeling was used. Data were analyzed for the overall sample and by generation, which was defined by year of birth. RESULTS: Of 291 patients (52% women, 82% non-Hispanic white, 50% age ≤ 60 years), 62% were cancer-related Internet users (CIUs). Cancer-related Internet use was associated with an income of ≥ $60,000 (odds ratio, 2.42; P = .004). CIUs used the Internet to learn about their cancer (85%), treatment adverse effects (65%), clinical trials (52%), new alternative treatments (42%), and symptom management (41%). CIUs most frequently used the hospital Web site (70%) to learn about clinical trials, followed by ClinicalTrials.gov (42%) and search engines (41%). The emotional impact of Internet-derived cancer information on CIUs varied-56% felt empowered, 34% anxious, 29% relieved, and 17% confused. Cancer-related Internet information made 51% of patients from the Millennial (born after 1990) and Generation X/Y (born 1965 to 1990) CIU populations anxious compared with < 29% of CIUs from older generations (born 1964 and before). Most CIUs desired more online information about new experimental drugs (91%) and US Food and Drug Administration-approved drugs for cancer (72%). CONCLUSION: As most phase I patients use the Internet for cancer-related purposes, the Internet overall and hospital Web sites should provide more extensive, pertinent, and helpful information on clinical trials and cancer treatment to phase I patients.

RESUMO

Ocular toxicities are among the most common adverse events resulting from targeted anticancer agents and are becoming increasingly relevant in the management of patients on these agents. The purpose of this study is to provide a framework for management of these challenging toxicities based on objective data from FDA labels and from analysis of the literature. All oncologic drugs approved by the FDA up to March 14, 2015, were screened for inclusion. A total of 16 drugs (12 small-molecule drugs and 4 monoclonal antibodies) were analyzed for ocular toxicity profiles based on evidence of ocular toxicity. Trials cited by FDA labels were retrieved, and a combination search in Medline, Google Scholar, the Cochrane database, and the NIH Clinical Trials Database was conducted. The majority of ocular toxicities reported were low severity, and the most common were conjunctivitis and "visual disturbances." However, severe events including incidents of blindness, retinal vascular occlusion, and corneal ulceration occurred. The frequency and severity at which ocular toxicities occur merits a more multidisciplinary approach to managing patients with agents that are known to cause ocular issues. We suggest a standardized methodology for referral and surveillance of patients who are potentially at risk of severe ocular toxicity.

RESUMO

BACKGROUND: The Supplemental Nutrition Assistance Program (SNAP) plays a critical role in reducing food insecurity by distribution of benefits at a monthly interval to participants. Households that receive assistance from SNAP spend at least three-quarters of benefits within the first 2 weeks of receipt. Because this expenditure pattern may be associated with lower food intake toward the end of the month, it is important to develop a tool that can assess the weekly diets of SNAP participants. OBJECTIVE: The goal of this study was to develop and assess the relative validity and reliability of a semiquantitative 1-week food frequency questionnaire (FFQ) tailored to a population of women participating in SNAP. DESIGN: The FFQ was derived from an existing 195-item FFQ that was based on a reference period of 1 month. This 195-item FFQ has been validated in a population of low-income postpartum women who were recruited from central Texas during 2004. Mean daily servings of each food item in the 195-item FFQ completed by women who took part in the 2004 validation study were calculated to determine the most frequently consumed food items. Emphasis on these items led to the creation of a shorter, 1-week FFQ of only 95 items. This new 1-week instrument was compared with 3-day diet records to evaluate relative validity in a sample of women participating in SNAP. For reliability, the FFQ was administered a second time, separated by a 1-month time interval. PARTICIPANTS/SETTING: The validity study included 70 female SNAP participants who were recruited from the partner agencies of the Central Texas Food Bank from March to June 2015. A subsample of 40 women participated in the reliability study. MAIN OUTCOME MEASURES: Outcome measures were mean nutrient intake values obtained from the two tests of the 95-item FFQ and 3-day diet records. STATISTICAL ANALYSIS PERFORMED: Deattenuated Pearson correlation coefficients examined relationships in nutrient intake between the 95-item FFQ and 3-day diet records, and a paired samples t test determined differences in mean nutrient intake. Weighted Cohen's κ indicated agreement in quartile classification of study participants by the 95-item FFQ and 3-day diet records, according to nutrient intake. Test-retest reliability was assessed by intraclass correlations and weighted Cohen's κ. RESULTS: Mean deattenuated Pearson correlation between the FFQ and 3-day diet records was 0.61, and the weighted Cohen's κ=0.39. Finally, the average test-retest correlation and weighted Cohen's κ of the FFQ was 0.66 and 0.50, respectively. CONCLUSIONS: These results suggest that the 1-week, 95-item FFQ demonstrated acceptable relative validity and reliability in low-income women participating in SNAP in southwestern United States.

RESUMO

Purpose: The Affordable Care Act (ACA) required that private insurance plans allow clinical trial participation and cover standard-of-care costs, but the impact of this provision has not been well-characterized. We assessed rates of insurance clearance for trial participation within our large early-phase clinical trials program, before and after implementation of the requirement.Experimental Design: We analyzed the departmental database for the Clinical Center for Targeted Therapy (CCTT) at MD Anderson Cancer Center (Houston, TX). Among patients referred for sponsored trials, we described rates of insurance clearance and prolonged time to clearance (at least 14 days) from July 2012 to June 2013 (baseline), July 2013-December 2013 (following CCTT staffing changes in July 2103), and January 2014-June 2015 (following implementation of the ACA). We used multivariable logistic regression models to compare rates across these time periods.Results: We identified 2,404 referrals for insurance clearance. Among privately insured patients, insurance clearance rates were higher for those referred from January 2014 to June 2015 than for those referred from July 2012 to June 2013 (OR, 4.72; 95% CI, 2.96-7.51). There was no association between referral period and clearance rates for Medicare/Medicaid patients (P = 0.25). Referral from January 2014 to June 2015 was associated with lower rates of prolonged clearance among both privately insured (OR 0.57; 95% CI, 0.38-0.86) and Medicare/Medicaid patients (OR 0.39; 95% CI, 0.19-0.83).Conclusions: Within our large early-phase clinical trials program, insurance clearance rates among privately insured patients improved following implementation of the ACA's requirement for coverage of standard-of-care costs.

RESUMO

BACKGROUND: Limited data exist about sleep quality for patients with advanced cancer in phase 1 clinical trials. Poor sleep quality is often not captured as an adverse event, and its association with fatigue, one of the most frequently reported adverse events, is not documented routinely. This article describes sleep quality and its relation with fatigue, symptom burden, and mood in patients recruited from an early-phase clinic for targeted therapy. METHODS: Sleep, fatigue, symptom burden, and mood were assessed with the Pittsburgh Sleep Quality Index (PSQI), the Brief Fatigue Inventory, the MD Anderson Symptom Inventory (MDASI), and the Brief Profile of Mood States, respectively; the Eastern Cooperative Oncology Group (ECOG) performance status (PS) was determined from medical records. RESULTS: The sample (n = 256) was 51.2% female, 90% had an ECOG PS of 0 or 1, and the mean age was 58 ± 0.8 years. Poor sleepers (global PSQI score > 5) constituted 64% of the sample. In separate multiple regression models, poor sleepers had higher levels of fatigue (P < .001), symptom burden (P < .001), and overall mood disturbance (P < .001) than good sleepers. Also, compared with good sleepers, poor sleepers had greater fatigue-related and symptom-related interference with daily activities (all P values < .001). The MDASI disturbed-sleep item correlated well with the global PSQI score (Pearson's r = 0.679, P < .001), and this suggests its usefulness as a patient-reported outcome screener of sleep quality in early-phase clinical trials clinics. CONCLUSIONS: Poor sleep quality was a significant problem in the current study and was associated with greater fatigue, symptom burden, and mood disturbance. Sleep quality should be routinely assessed in patients with advanced cancer who are participating in early-phase clinical trials. Cancer 2016;122:3401-3409. © 2016 American Cancer Society.

RESUMO

Uncovering CTCs phenotypes offer the promise to dissect their heterogeneity related to metastatic competence. CTC survival rates are highly variable and this can lead to many questions as yet unexplored properties of CTCs responsible for invasion and metastasis vs dormancy. We isolated CTC subsets from peripheral blood of patients diagnosed with or without breast cancer brain metastasis. CTC subsets were selected for EpCAM negativity but positivity for CD44(+)/CD24(-) stem cell signature; along with combinatorial expression of uPAR and int ß1, two markers directly implicated in breast cancer dormancy mechanisms. CTC subsets were cultured in vitro generating 3D CTC tumorspheres which were interrogated for biomarker profiling and biological characteristics. We identified proliferative and invasive properties of 3D CTC tumorspheres distinctive upon uPAR/int ß1 combinatorial expression. The molecular characterization of uPAR/int ß1 CTC subsets may enhance abilities to prospectively identify patients who may be at high risk of developing BCBM.

RESUMO

OBJECTIVE AND METHODS: In this phase 1b study, patients with stage 4 or unresectable stage 3 melanoma were treated with escalating doses of lenvatinib (once daily) and temozolomide (TMZ) (days 1-5) in 28-day cycles, to determine the maximum tolerated dose (MTD) of the combination. Dose Level (DL)1: lenvatinib 20 mg, TMZ 100 mg/m2; DL2: lenvatinib 24 mg, TMZ 100 mg/m2; DL3: lenvatinib 24 mg, TMZ 150 mg/m2. Adverse events (AEs) were recorded and tumor response assessed per RECIST 1.0. RESULTS: Dose-limiting toxicity occurred in 1 of 32 treated patients (DL1); MTD was not reached. The highest dose administered was lenvatinib 24 mg + TMZ 150 mg/m2. Most common treatment-related AEs included fatigue (56.3%), hypertension (53.1%), and proteinuria (46.9%). Overall objective response rate was 18.8% (6 patients), all partial response; (DL1, n = 1; DL3, n = 5). Stable disease (SD) ≥ 16 weeks was observed in 28.1% of patients (DL1 and DL2, n = 1 each; DL3, n = 7); 12.5% of patients had SD ≥ 23 weeks. Single and repeat-dose pharmacokinetics of lenvatinib were comparable across cycles and with concomitant TMZ administration. CONCLUSIONS: Lenvatinib 24 mg/day + TMZ 150 mg/m2/day (days 1-5) demonstrated modest clinical activity, an acceptable safety profile, and was administered without worsening of either lenvatinib- or TMZ-related toxicities in this patient group.

RESUMO

PURPOSE: This "3+3" phase I study evaluated the safety, biologic, and clinical activity of lenvatinib, an oral multikinase inhibitor, in patients with solid tumors. EXPERIMENTAL DESIGN: Ascending doses of lenvatinib were administered per os twice daily in 28-day cycles. Safety and response were assessed for all patients. Angiogenic and apoptotic factors were tested as possible biomarkers in an expanded melanoma cohort. RESULTS: Seventy-seven patients were treated in 3 cohorts: 18 with intermittent twice-daily dosing (7 days on, 7 days off) of 0.1-3.2 mg; 33 with twice-daily dosing of 3.2-12 mg; and 26 with twice-daily dosing of 10 mg (expanded melanoma cohort). Maximum tolerated dose was established at 10 mg per os twice daily. Prominent drug-related toxicities included hypertension (43%), fatigue (42%), proteinuria (39%), and nausea (25%); dose-limiting toxicities included hypertension, fatigue, and proteinuria. Twelve patients (15.6%) achieved partial response (PR, n = 9) or unconfirmed PR (uPR, n = 3), and 19 (24.7%) achieved stable disease (SD) ≥23 weeks. Total PR/uPR/SD ≥23 weeks was 40.3% (n = 31). Responses (PR/uPR) by disease were as follows: melanoma, 5 of 29 patients (includes 1 patient with NRAS mutation); thyroid, 3 of 6 patients; pancreatic, 1 of 2 patients; lung, 1 of 1 patients; renal, 1 of 1 patients; endometrial, 1 of 4 patients; and ovarian, 1 of 5 patients. AUC(0-24) and C(max) increased dose proportionally. In multivariate Cox proportional hazard model analyses, increased baseline systolic blood pressure and decreased angiopoietin-1 ratio (2 hours:baseline) were associated with longer progression-free survival (PFS) in the expanded melanoma cohort (P = 0.041 and P = 0.03, respectively). CONCLUSIONS: The toxicity profile, pharmacokinetics, and antitumor activity of lenvatinib are encouraging. Decreases in the angiopoietin-1 ratio correlated with longer PFS in melanoma patients.
