Prognostic value of symptom burden for overall survival in patients receiving chemotherapy for advanced nonsmall cell lung cancer

Symptomatologic outcomes of gut microbiota modifiers (probiotics, prebiotics and synbiotics) in cancer care: A scoping review of randomized controlled trials

BACKGROUND

Microbiota modifiers offer potential benefits for improving the wide spectrum of symptoms and clinical outcomes in individuals with cancer. However, there is a lack of comprehensive literature mapping to determine which specific cancer and treatment-related symptoms have been investigated as potential targets for gut microbiota modifiers. This scoping review aims to systematically analyze clinical trials on microbiota modifiers in managing cancer and treatment-related symptoms in adults.

METHODS

We conducted a scoping review of randomized controlled trials (RCTs) across four databases up to May 2025, following our published protocol and JBI principles with PRISMA 2020 guidelines.

RESULTS

The literature review identified 33 eligible studies, primarily involving patients with pelvic cancers. The most common outcomes examined in the clinical trials were gastrointestinal symptoms. Other studies focused on patients with head, neck, and breast cancer, examining quality of life, mucositis, fatigue, anxiety, depression, and the use of rescue drugs.

CONCLUSION

Despite evidence of potential benefits for gastrointestinal symptoms, inconsistent findings across studies warrant further well-designed, large-scale research to understand probiotics' effectiveness and mechanisms.

Shared decision making in routine oncology appointments with Black patients with lung cancer

PURPOSE

Poor clinician-patient communication may contribute to racialized inequities in cancer symptom burden. Shared decision-making (SDM) enhances clinician-patient communication, and could contribute to health equity for Black patients with cancer. However, research on SDM is limited for Black patients with cancer.

METHODS

This multi-method longitudinal observational study examined SDM during routine oncology follow-ups for patients with advanced lung cancer. We analyzed SDM reported by clinicians (n = 6), self-identified Black patients with lung cancer (n = 30), and coded from patient visit recordings (n = 20). We described the symptom management conversations, and examined how SDM related to patient satisfaction and symptom severity with two-sided correlations.

RESULTS

Most patients (85.0%) asked questions during appointments and discussed cancer-related symptoms (95.0%), most commonly pain/neuropathy (65.0%). Though coded SDM during symptom discussions was low, providers and patients reported high levels of SDM. Coded SDM did not statistically significantly correlate with post-appointment satisfaction (r = -.01, p > .10) or symptom burden (r = .04, p > .10). However, patient-reported SDM did relate to post-appointment satisfaction (r = .72, p = .08) and symptom burden (r = .35, p = .08) one month later.

CONCLUSIONS

Through detailed multi-method analysis, we found that coded SDM did not correspond to patient and physician-reported SDM during routine oncology appointments. Patient-reported SDM correlated to several better physical and mental health outcomes as well as overall satisfaction a month later. Our findings highlight the complexities of clinician-patient communication and the importance of studying these processes for Black patients with cancer. Future research should develop culturally-relevant methods of assessing SDM with Black patients and understand Black patients' communication needs.

Systemic inflammation and changes in physical well-being in patients with breast cancer: a longitudinal study in community oncology settings

BACKGROUND

Chemotherapy adversely affects physical well-being and inflammation may be related to changes in physical well-being. We evaluated the association of systemic inflammation with changes in physical well-being.

METHODS

In a prospective study of 580 patients with stages I-III breast cancer we assessed immune cell counts, neutrophil:lymphocyte ratio (NLR), lymphocyte:monocyte ratio (LMR), and platelet:lymphocyte ratio (PLR) within 7 days before chemotherapy (pre-chemotherapy). Physical well-being was assessed using the Functional Assessment of Cancer Therapy: General-Physical Well-being subscale (FACT-PWB) pre-chemotherapy and 1 month and 6 months post-chemotherapy. Clinically meaningful decline in physical well-being was determined as decreasing FACT-PWB by more than one point from pre-chemotherapy level, and non-resilience defined as having decline post-chemotherapy and not returning to within one-point of pre-chemotherapy FACT-PWB by 6 months post-chemotherapy. Multivariable logistic regressions examined the association between inflammation and changes in physical well-being, adjusting for sociodemographic and clinical characteristics.

RESULTS

Fifty-nine percent (310/529) and 36% (178/501) of participants had physical well-being decline post-chemotherapy and 6 months post-chemotherapy, respectively. Fifty percent (147/294) were non-resilient. Low NLR and PLR were associated with 1.78 (P = .01) and 1.66 (P = .02) fold greater odds of having a decline in physical well-being 6 months post-chemotherapy compared to those with high NLR and PLR, respectively. Low NLR and PLR were associated with 1.92 (P = .02) and 2.09 (P = 0.01) fold greater odds of being non-resilient 6 months post-chemotherapy compared to those with high NLR and PLR, respectively.

CONCLUSION

Low NLR and PLR were associated with chemotherapy-induced changes in physical well-being independent of sociodemographic and clinical risk factors.

Sleep quality in lung cancer and specifically non-small-cell lung cancer: a rapid review

PURPOSE

Sleep quality contributes to the improvement of quality of life in cancer patients. However, sleep disturbances, of variable and heterogeneous etiologies, are common and frequently overlooked in lung cancer patients. The present study undertakes a rapid review of available peer-reviewed literature on sleep quality in lung cancer patients, specifically non-small-cell lung cancer patients.

DESIGN

MEDLINE, Embase, and CENTRAL online databases were used to identify 513 published articles from which 26 publications were selected through abstract and title screening, full-text review, and quality assessment.

RESULTS

Most publications (96.15%) involved observational studies, including 12 cross-sectional studies, 6 longitudinal studies, and 6 descriptive comparative studies. Sleep quality was assessed using either subjective or objective measures or both. Sleep disturbances were found in 45-97% of patients. Poor sleep efficiency and frequent night-time awakenings were consistently reported, whereas discrepancies were found concerning sleep duration and sleep latency.

CONCLUSION

Our rapid review of the literature confirms that sleep disorders, which impair quality of life, remain frequent and often neglected in this patient population. Assessment of sleep quality in patients with non-small-cell lung cancer should be the subject of further studies into how to better identify and characterize them to implement appropriate therapeutic strategies, using a global approach to improve quality of life despite the underlying cancerous disease.

Patient-reported outcomes after CAR T-cell therapy in patients with hematological malignancies

The remarkable improvement in survival among individuals with hematological malignancies receiving chimeric antigen receptor (CAR) T-cell therapy has highlighted the growing unmet need to incorporate patient-centered assessments in management guidelines for these patients. That CAR T-cell therapy is associated with unique toxicities and relatively high symptom burden in the first few weeks after cell infusion is well known. Magnifying the patient's voice by using patient-reported outcomes (PROs) might support personalized intervention in the acute-care setting, optimize the use of medical resources, improve satisfaction with therapy, and enhance survival benefit. However, various factors impede PRO use in routine patient care: (1) the feasibility of PRO assessment during the acute phase of treatment, especially in patients experiencing neurological toxicities, is not well established; (2) although PROs are widely used in drug- development trials, the assessment tools used in clinical trials primarily inform quality-of-life or safety comparisons among study arms and are rarely the proper tools for assessing and capturing clinically meaningful adverse events that should be monitored in routine patient care; (3) PRO data that could guide how best to monitor and capture the delayed effects of CAR T-cell therapy in long-term survivors are limited. There is a pressing need to overcome these barriers to integrating evidence-based PROs into standard-of-care guidelines for patients receiving CAR T-cell therapy. In this review, we present the current state of PRO utilization in CAR T-cell therapy. We also discuss practical approaches and future directions for successful implementation of PROs in the care of patients receiving CAR T-cell therapy.

Prognosis and risk factor assessment of patients with advanced lung cancer with low socioeconomic status: model development and validation

BACKGROUND

Lung cancer, a major global health concern, disproportionately impacts low socioeconomic status (SES) patients, who face suboptimal care and reduced survival. This study aimed to evaluate the prognostic performance of traditional Cox proportional hazards (CoxPH) regression and machine learning models, specifically Decision Tree (DT), Random Forest (RF), Support Vector Machine (SVM), and Extreme Gradient Boosting (XGBoost), in patients with advanced lung cancer with low SES.

DESIGN

A retrospective study.

METHOD

The 949 patients with advanced lung cancer with low SES who entered the hospice ward of a tertiary hospital in Wuhan, China, from January 2012 to December 2021 were randomized into training and testing groups in a 3:1 ratio. CoxPH regression methods and four machine learning algorithms (DT, RF, SVM, and XGBoost) were used to construct prognostic risk prediction models.

RESULTS

The CoxPH regression-based nomogram demonstrated reliable predictive accuracy for survival at 60, 90, and 120 days. Among the machine learning models, XGBoost showed the best performance, whereas RF had the lowest accuracy at 60 days, DT at 90 days, and SVM at 120 days. Key predictors across all models included Karnofsky Performance Status (KPS) score, quality of life (QOL) score, and cough symptoms.

CONCLUSIONS

CoxPH, DT, RF, SVM, and XGBoost models are effective in predicting mortality risk over 60-120 days in patients with advanced lung cancer with low SES. Monitoring KPS, QOL, and cough symptoms is crucial for identifying high-risk patients who may require intensified care. Clinicians should select models tailored to individual patient needs and preferences due to varying prediction accuracies.

REPORTING METHOD

This study was reported in strict compliance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guideline.

Clinicians' Prediction of Survival Is Most Useful for Palliative Care Referral

Background

Timely palliative transition in patients with advanced cancer is essential for their improved quality of life and overall survival (OS). Most prognostic models have been developed focusing on weeks' survival. The current study aimed to compare the accuracies of several indicators, such as the Karnofsky Performance Scale (KPS), Clinicians' Prediction of Survival (CPS), and Edmonton Symptom Assessment System (ESAS), for predicting the survival of patients.

Methods

Two hundred patients were enrolled at a single tertiary cancer center in South Korea between 2016 and 2019. We compared the discrimination of CPS versus KPS and ESAS total scores using the area under the receiver operating characteristic curve (AUROC) in 3-month and 6-month survival predictions.

Results

The median age of patients was 66.0 years, and 128 (64%) were male. Two-thirds (66%) of the patients had an Eastern Cooperative Oncology Group performance status of 0 or 1, and 55.5% had a KPS of 80% or higher. The values of AUROC of CPS, KPS, and ESAS total score in 3-month survival prediction were 0.80 (95% confidence interval [CI]: 0.73-0.88), 0.71 (95% CI: 0.62-0.79), and 0.71 (95% CI: 0.62-0.81), respectively, whereas those in 6-month survival were 0.82 (95% CI: 0.76-0.88), 0.70 (95% CI: 0.63-0.78), and 0.63 (95% CI: 0.55-0.71), respectively.

Conclusion

CPS showed the highest accuracy in predicting 3- and 6-month survival, whereas KPS had an acceptable accuracy. Experienced clinicians can rely on CPS to predict survival in months. We recommend the use of KPS with CPS to assist inexperienced clinicians.

Physical Deconditioning in Lung Cancer Patients Who Underwent Lung Resection Surgery in Spain: A Prospective Observational Study

BACKGROUND

Lung resection represents the main curative treatment modality for lung cancer. These patients present with physical deterioration that has been studied previously using objective variables; however, no previous studies have evaluated the self-perceived physical fitness of these patients. For these reasons, to increase the current knowledge on lung cancer patients' impairment, the aim of this study was to characterize the self-perceived physical deconditioning of lung cancer patients undergoing lung resection in the short and medium term after surgery.

METHODS

A longitudinal, observational, prospective cohort study was performed in the Thoracic Surgery Service of the Hospital Virgen de las Nieves (Granada). Symptoms (pain, fatigue, cough and dyspnea) and physical fitness (upper and lower limbs) were assessed before surgery, at discharge and at one month after discharge.

RESULTS

Among the total of 88 patients that we included in our study, significant differences were found at discharge in symptoms (p < 0.05) and physical fitness (p < 0.05). One month after surgery, higher levels of pain (p = 0,002) and dyspnea (p = 0.007) were observed, as well as poorer results in the upper (p = 0.023) and lower limbs' physical fitness, with regard to the initial values.

CONCLUSIONS

Patients undergoing lung resection present an increase in symptoms and physical fitness deterioration at discharge, which is maintained one month after surgery.

Patient-reported outcome (PRO)-based symptom assessment in patients with advanced lung cancer receiving first-line combination immunotherapy: a protocol for a multicenter, prospective, observational study

BACKGROUND

Immunotherapy is currently applied in the first-line treatment regimens for numerous advanced cancers, especially advanced lung cancer. Immune-related adverse events (irAEs) resulting from immunotherapy can vary in severity and cause a substantial symptom burden to patients. However, there are limited data on symptom burden in patients with advanced lung cancer following immunotherapy. To address this deficit, this study aims to provide insight into the symptom burden and severity through patient-reported outcome measurements and conduct an analysis of temporal trends and clinical consequences of symptom burden in patients with advanced lung cancer receiving combination immunotherapy.

METHODS

We will prospectively recruit 168 eligible patients from 14 hospitals in China. Eligible patients will be aged ≥ 18 years, pathologically diagnosed with locally advanced or stage IV primary lung cancer without surgical indications, and agreed to receive immunotherapy in combination with other therapies. The primary outcome of this study is the symptom burden of patients during the immunotherapy course. Longitudinal symptom data will be collected using the MD Anderson Symptom Inventory-Lung Cancer module (MDASI-LC) and the symptomatic irAEs scale at baseline (once before treatment) and weekly after treatment, until 1 month after the last treatment cycle has been completed. The trajectory of symptom burden following combination immunotherapy will be depicted, and by linking it to clinical outcomes (the secondary outcome and exploratory outcome of this study), the consequence of symptom burden in patients with advanced lung cancer receiving combination immunotherapy will be examined further.

DISCUSSION

This study intends to establish longitudinal symptom trajectories in patients with lung cancer receiving immunotherapy, and explore its association with clinical outcomes. These findings may serve as an important reference for clinicians in the symptomatic management of patients with lung cancer receiving immunotherapy.

Quality-of-life outcomes and risk prediction for patients randomized to nivolumab plus ipilimumab vs nivolumab on LungMAP-S1400I

BACKGROUND

An important issue for patients with cancer treated with novel therapeutics is how they weigh the effects of treatment on survival and quality of life (QOL). We compared QOL in patients enrolled to SWOG S1400I, a substudy of the LungMAP biomarker-driven master protocol.

METHODS

SWOG S1400I was a randomized phase III trial comparing nivolumab plus ipilimumab vs nivolumab for treatment of immunotherapy-naïve disease in advanced squamous cell lung cancer. The primary endpoint was the MD Anderson Symptom Inventory-Lung Cancer severity score at week 7 and week 13 with a target difference of 1.0 points, assessed using multivariable linear regression. A composite risk model for progression-free and overall survival was derived using best-subset selection.

RESULTS

Among 158 evaluable patients, median age was 67.6 years and most were male (66.5%). The adjusted MD Anderson Symptom Inventory-Lung Cancer severity score was 0.04 points (95% confidence interval [CI] = -0.44 to 0.51 points; P = .89) at week 7 and 0.12 points (95% CI = -0.41 to 0.65; P = .66) at week 13. A composite risk model showed that patients with high levels of appetite loss and shortness of breath had a threefold increased risk of progression or death (hazard ratio [HR] = 3.06, 95% CI = 1.88 to 4.98; P < .001) and that those with high levels of both appetite loss and work limitations had a fivefold increased risk of death (HR = 5.60, 95% CI = 3.27 to 9.57; P < .001)-compared with those with neither risk category.

CONCLUSIONS

We found no evidence of a benefit of ipilimumab added to nivolumab compared with nivolumab alone for QOL in S1400I. A risk model identified patients at high risk of poor survival, demonstrating the prognostic relevance of baseline patient-reported outcomes even in those with previously treated advanced cancer.

Racial and ethnic inequities of palliative care use among advanced Non‐Small cell lung cancer patients in the US

BACKGROUND

With early intervention, palliative care (PC) can improve quality of life and increase survival among advanced-stage non-small cell lung cancer (aNCSLC) patients. However, PC is often offered late in the cancer treatment course and is underused. We characterized racial/ethnic inequities and the role of healthcare access in PC use among patients with aNSCLC.

METHODS

We used data from the 2004-2016 National Cancer Database, including adults aged 18-90 years with aNSCLC (stage 3 or 4 at diagnosis; n = 803,618). Based on the NCCN guidelines, PC includes non-curative surgery, radiation, chemotherapy, pain management, or any combination of non-curative care. We examined PC use by sociodemographic and health care-level characteristics. To evaluate the independent associations of race/ethnicity and health care access characteristics with PC, we estimated adjusted odds ratios (aOR) with 95% confidence intervals (95% CI). Covariate adjustment sets varied by exposure determined using directed acyclic graphs.

RESULTS

Our population was 55% male and 77% non-Hispanic/Latinx (NH)-White, with a mean age of 68 years. Overall, 19% of patients with aNSCLC used PC. Compared to NH-White patients, NH-Black (aOR:0.91,95% CI:0.89-0.93) and Hispanic/Latinx (aOR:0.80,95% CI:0.77-0.83) patients were less likely to use PC, whereas Indigenous (AI/AN) (aOR:1.18,95% CI:1.06-1.31) and Native Hawaiian/Pacific Islander (aOR:2.08,95% CI:1.83-2.36) patients were more likely. Overall, compared to the privately-insured, uninsured (aOR:1.19,95% CI:1.11-1.28) and Medicaid-insured patients (aOR:1.19,95% CI:1.14-1.25) were more likely to use PC.

CONCLUSION

PC is underutilized among NH-Black and Hispanic/Latinx patients with aNSCLC. Insurance type may play a role in PC use among patients with aNSCLC.

Association of post-treatment longitudinal symptom severity clusters with subsequent survival in oropharyngeal cancer

BACKGROUND

Patients with cancer often experience multiple symptoms concurrently. We identified patient clusters based on longitudinal symptom severity trajectories in oropharyngeal cancer (OPC) and evaluated the potential clinical utility of this approach.

METHODS

A retrospective OPC patient cluster analysis using 6 months of symptom severity data from radiotherapy initiation. The clinico-demographic characteristics and overall survival of patients were compared between clusters.

RESULTS

We identified four clusters of patients differing in longitudinal symptom severity. Cluster A (n = 168) included patients with the mildest longitudinal symptoms, cluster B (n = 59) and cluster C (n = 63) were intermediate, and cluster D (n = 30) included patients with the worst symptoms. The clusters differed in their HPV status, ECOG performance status, smoking history, drinking history, treatment modality, and 5-year survival. These clusters separated symptom severity trajectories more distinctly than individual clinico-demographic characteristics.

CONCLUSIONS

Early symptom severity trajectory clustering revealed distinct patient clusters that were prognostic of overall survival.

Strategies for improving the management of immune-related adverse events

With the advent of immunotherapeutic agents, durable and dramatic responses have been observed in several hard-to-treat malignancies, outlining a roadmap to conquering cancer. Immune checkpoint inhibitors (ICPi) are a class of immunotherapeutic agents that attack the tumor cells by reinvigorating the suppressed immune system. However, the unbridled T-cell activity disrupts the immune homeostasis and induces a unique spectrum of side effects called immune-related adverse events (irAEs) in a significant proportion of patients. These irAEs are distinct from the side effects produced by traditional chemotherapeutic agents. Although majority of irAEs are manageable with corticosteroids and other immunosuppressive agents, life-threatening and fatal events have been reported. In the absence of predictive biomarkers to identify patients at risk for irAEs and standardized approach to detect, report, and treat irAEs, management of irAEs has been challenging to the patients, caregivers and the healthcare providers alike. With increasing use of ICPis for treatment of various cancers, the incidence of irAEs will undoubtedly increase. There is a compelling need to develop measures to effectively manage irAEs, both in the community settings and in cancer centers alike. To this end, in this paper, we propose several strategies, such as providing patient education, harmonizing irAE management guidelines, standardizing reporting of irAEs, optimizing the choice of immunosuppressive agents, conducting preclinical, clinical and translational studies to better understand irAEs, including high-risk patients, incorporating diagnostic tools to personalize irAE management using wireless technology and digital health, providing a platform to hear the missing patient's voice, and sharing evolving data to improve the management of irAEs.

Homeopathic Treatment as an Add-On Therapy May Improve Quality of Life and Prolong Survival in Patients with Non-Small Cell Lung Cancer: A Prospective, Randomized, Placebo-Controlled, Double-Blind, Three-Arm, Multicenter Study

LESSONS LEARNED

Conventional medicine and homeopathy work well together. Quality of life improves with additive homeopathy in patients with non-small cell lung cancer (NSCLC). Survival improves with additive homeopathy in patients with NSCLC.

BACKGROUND

Patients with advanced non-small cell lung cancer (NSCLC) have limited treatment options. Alongside conventional anticancer treatment, additive homeopathy might help to alleviate side effects of conventional therapy. The aim of the present study was to investigate whether additive homeopathy might influence quality of life (QoL) and survival in patients with NSCLC.

METHODS

In this prospective, randomized, placebo-controlled, double-blind, three-arm, multicenter, phase III study, we evaluated the possible effects of additive homeopathic treatment compared with placebo in patients with stage IV NSCLC, with respect to QoL in the two randomized groups and survival time in all three groups. Treated patients visited the outpatients' centers every 9 weeks: 150 patients with stage IV NSCLC were included in the study; 98 received either individualized homeopathic remedies (n = 51) or placebo (n = 47) in a double-blinded fashion; and 52 control patients without any homeopathic treatment were observed for survival only. The constituents of the different homeopathic remedies were mainly of plant, mineral, or animal origin. The remedies were manufactured by stepwise dilution and succussion, thereby preparing stable Good Manufacturing Practice grade formulations.

RESULTS

QoL as well as functional and symptom scales showed significant improvement in the homeopathy group when compared with placebo after 9 and 18 weeks of homeopathic treatment (p < .001). Median survival time was significantly longer in the homeopathy group (435 days) versus placebo (257 days; p = .010) as well as versus control (228 days; p < .001). Survival rate in the homeopathy group differed significantly from placebo (p = .020) and from control (p < .001).

CONCLUSION

QoL improved significantly in the homeopathy group compared with placebo. In addition, survival was significantly longer in the homeopathy group versus placebo and control. A higher QoL might have contributed to the prolonged survival. The study suggests that homeopathy positively influences not only QoL but also survival. Further studies including other tumor entities are warranted.

Distinct Subgroups of Patients With Lung Cancer Receiving Chemotherapy: A Latent Transition Analysis

Objectives

To identify subgroups of patients with lung cancer receiving chemotherapy based on the severity dimension of symptom experience, and to examine changes in membership between these subgroups over time.

Methods

Patients who were scheduled to receive chemotherapy completed the Chinese version of the MD Anderson Symptom Inventory and the revised lung cancer module with a total of 19 symptom items. Data were collected at three time points: two weeks before chemotherapy (T1), after chemotherapy cycle 1 (T2), and after chemotherapy cycle 3 or above (T3). The latent profile analysis and latent transition analysis were used to identify underlying subgroups and describe changes in subgroup membership over time.

Results

From the total sample (N = 195), 160 patients completed the symptom assessment at T1, T2, and T3. Two distinct latent symptom profiles of patients could be identified at T1, T2, and T3, which were classified as "Mild" and "Moderate-Severe" profiles. From T1 to T2 and T3, members in the Mild profile were more likely to move to the Moderate-Severe profile. Chemotherapy protocols, prior surgery treatment, and level of education can predict the transitions.

Conclusion

Results provide a better understanding of the patient's different symptom experiences and characteristics. These could help clinicians to anticipate symptom patterns and develop interventions in lung cancer patients who were scheduled to receive chemotherapy for the first time.

Symptom burden trajectories experienced by patients with brain tumors

BACKGROUND

Survivors of childhood brain tumors experience persistent health concerns across their lifespan. In the current study, the authors evaluated changes in symptom burden over the course of 12 months using pediatric Patient-Reported Outcomes Measurement Information System (PROMIS) measures.

METHODS

Data from 202 survivors aged 8 to 21 years and 262 parents of survivors who were aged 5 to 21 years were analyzed. All completed a PROMIS Cognition short form and computerized adaptive tests of pediatric Anxiety, Depressive Symptoms, Fatigue, Mobility, Upper Extremity Function, and Peer Relationships. Approximately one-half of participants (223 participants: 97 survivors of childhood brain tumors and 126 parents) completed the 12-month follow-up. Linear mixed-effects models evaluated group-level symptoms over time. Cox proportional hazard models explored whether symptoms predicted survival, and latent class growth analysis investigated patterns of individual-level symptom changes over time.

RESULTS

Linear mixed-effects models demonstrated that patient-reported Cognition and parent-reported Anxiety worsened over time. Latent class growth analysis results indicated that patient and parent reports diverged, both with regard to the number of classes identified and in the trends of these classes. Parents and patients reported similar patterns of depression over time. For the other areas, parents either were more likely to observe different patterns (Peer Relationships and Mobility) or less likely to observe different patterns (Upper Extremity Function, Cognition, Anxiety, and Fatigue). Baseline patient-reported Mobility and Upper Extremity Function were found to be associated with survival.

CONCLUSIONS

Survivors of childhood brain tumors demonstrated different trajectory patterns of symptom burden. Along with baseline functioning status and days since treatment, patient-reported Mobility and Upper Extremity Function were associated with survival, suggesting a possible role for patient-reported outcomes in clinical care, especially individualized, tailored assessments such as PROMIS.

Lifestyle and Sociodemographic and Economic Characteristics of Patients with Lung Cancer in Morocco

Background

Lifestyle maintenance is a crucial condition before and after lung cancer disease. According to the previous research in the scientific databases, the effect of the interaction between socioeconomic and demographic factors on the lifestyle of lung cancer patients in Southern Morocco regions remains unexamined. Accordingly, this study was designed to examine the relationship between socioeconomic factors, demographic factors, and the lifestyle of lung cancer patients.

Methods

A total of 133 patients with lung cancer were divided into 103 men and 30 women with a sex ratio of 3.43 and ages varying between 28 and 82 years, and they served as informants for the study and filled in a questionnaire to provide information on their sociodemographic background, various economic characteristics, and their lifestyle. These patients have also been submitted to an anthropometric examination following the standardized procedure recommended by the World Health Organization. The survey was conducted from July 2013 to March 2015 at the Oncology and Radiotherapy Department, at Mohammed VI Hospital Center in Marrakech, Morocco.

Results

The preliminary results showed that the average age of patients was 59 ± 9 years. A proportion of 81% lived in the Marrakech-Safi region and 19% lived in four other southern regions. Among the patients, 6% were smokers, while 14% were nonsmokers and 80% were ex smokers. Following the discovery of the disease, 26% revealed that they had sleep disorders and 98% were reported to have a lack of appetite. Obesity, normal weight, and underweight were also taken as criteria to categorize the patients; thus, obese informants represented 23% of the total number, those having normal weight reached 67% and the patients having underweight represented 10%.

Conclusion

Sociodemographic variables and various economic characteristics were shown to have a negative impact on the lifestyle of lung cancer patients.

Association Between Symptom Burden and Physical Function in Older Patients with Cancer

OBJECTIVES

To evaluate the independent association between symptom burden and physical function impairment in older adults with cancer.

DESIGN

Cross-sectional.

SETTING

Two university-based geriatric oncology clinics.

PARTICIPANTS

Patients with cancer aged 65 years or older who underwent evaluation with geriatric assessment (GA).

MEASUREMENTS

Symptom burden was measured as a summary score of severity ratings (range = 0-10) of 10 commonly reported symptoms using a Clinical Symptom Inventory (CSI). Functional impairment was defined as the presence of one or more impairments of instrumental activities of daily living (IADLs), any significant physical activity limitation on the Medical Outcomes Survey (MOS), one or more recent falls in the previous 6 months, or a Short Physical Performance Battery (SPPB) score of 9 or less. Multivariate analysis evaluated the association between symptom burden and physical function impairment, adjusting for other clinical and sociodemographic variables.

RESULTS

From 2011 to 2015, 359 patients with cancer and a median age of 81 years (range = 65-95 y) consented. The mean CSI score was 23.2 ± 20.5 with an observed range of 0 to 90. Patients in the highest quartile of symptom burden (N = 91; CSI score 52 ± 13) had a higher prevalence of IADL impairment (91% vs 51%), physical activity limitation (93% vs 65%), falls (55% vs 21%), and SPPB score of 9 or less (92% vs 69%) (all P values <.01) when compared with those in the bottom quartile (N = 81; CSI score: 2 ± 2). With each unit increase in CSI score, the odds of having IADL impairment, physical activity limitations, falls, and SPPB scores of 9 or less increased by 4.8%, 4.4%, 2.9%, and 2.5%, respectively (P < .05 for all results).

CONCLUSIONS

In older patients with cancer, higher symptom burden is associated with functional impairment. Future studies are warranted to evaluate if improved symptom management can improve function in older cancer patients. J Am Geriatr Soc 67:998-1004, 2019.

A research protocol for a pilot randomized controlled trial designed to examine the feasibility of a couple-based mind-body intervention for patients with metastatic lung cancer and their partners

Background

Given the generally incurable nature of metastatic non-small cell lung cancer (mNSCLC), patients and their romantic partners are at risk for existential/spiritual distress. Although a handful of dyadic psychosocial interventions for lung cancer patients and their caregivers exist, none of them target spiritual well-being. Informed by the mindfulness-based intervention literature and our pilot work in couples affected by lung cancer, we developed a brief couple-based mind-body (CBMB) intervention. The primary aim of this research protocol is to determine the feasibility of implementing the CBMB intervention versus an active control (AC) or wait list control (WLC) group in patients with mNSCLC and their partners using a randomized controlled trial design.

Methods

Seventy-five patients with mNSCLC receiving treatment and their partners are randomized to the CBMB intervention, an AC or a WLC group. Those in the CBMB intervention and AC groups receive four intervention sessions of 60 min each over 4 weeks and complete weekly homework assignments. The first session is delivered in person, and the remaining sessions are delivered via videoconference. The dyads in the AC group discuss cancer-related and personal growth concerns with the interventionist but are not taught coping skills. Patients and partners in all groups complete baseline assessments of quality of life (QOL) prior to randomization. Follow-up assessments are performed 4 weeks and then again 3 months later. The primary outcome is feasibility (i.e., ≥ 30% of eligible couples consent, ≥ 70% of enrolled couples are retained, and ≥ 50% of all CBMB and AC sessions are attended). We will also perform primarily descriptive analyses of the self-reported outcomes (e.g., spiritual well-being and psychological distress) and explore potential intervention mediators (i.e., compassion, communication, mindfulness, and closeness) to inform a larger, future trial.

Discussion

This trial will provide important information regarding the feasibility of a behavioral intervention in a vulnerable yet understudied population using videoconferencing and descriptive data regarding spiritual well-being and other indices of QOL in both mNSCLC patients and their partners.

Predictors of the multidimensional symptom experience of lung cancer patients receiving chemotherapy

PURPOSE

Few studies have examined interindividual variability in the symptom experience of lung cancer patients. We aimed to identify the most prevalent, severe, and distressing symptoms, and risk factors associated with increased symptom burden.

METHODS

Lung cancer patients (n = 145) reported occurrence, severity, and distress for 38 symptoms on the Memorial Symptom Assessment Scale 1 week after chemotherapy. Using multidimensional subscales, risk factors for higher global distress, physical, and psychological symptoms were evaluated using simultaneous linear regression.

RESULTS

Mean age was 64.0 years and 56.6% were female. Mean Karnofsky Performance Status score was 79.1 (SD 14.6) and mean Self-Administered Comorbidity Questionnaire score was 7.3 (SD 3.9). The most distressing and prevalent symptom was fatigue. Problems with sexual interest/activity had the highest mean severity rating. Patients with lower functional status (p = 0.001) and higher comorbidity (p = 0.02) reported higher global distress. Similarly, lower functional status (p = 0.003) and higher comorbidity (p = 0.04) were associated with a higher physical symptom burden along with lower body mass index (p = 0.02). Higher psychology symptom burden was associated with lower functional status (p = 0.01), younger age (p = 0.02), non-metastatic disease (p = 0.03), higher number of prior treatments (p = 0.04), and income (p = 0.03).

CONCLUSIONS

Fatigue was the most distressing and prevalent symptom among lung cancer patients receiving chemotherapy. Lower functional status was associated with a higher burden of global distress, physical, and psychological symptoms. Younger age and non-metastatic disease were additional risk factors for increased psychological symptoms. Together, these risk factors can help clinicians identify lung cancer patients at increased need for aggressive symptom management.

A systematic review of the impact of pain on overall survival in patients with cancer

PURPOSE

Pain commonly occurs in cancer patients, and has been associated with shorter survival. However, the importance of pain is less clear when analyzed with other known prognostic variables. This systematic review was performed to better understand how pain impacts overall survival (OS) in common cancers when key clinical variables are included in multivariate analysis.

METHODS

A Medline search was completed to find studies examining the relationship between pain, clinical variables, and OS in patients with breast, colorectal, lung, or prostate cancer. Multivariate analysis included known prognostic variables including age, performance status, disease burden, and laboratory parameters.

RESULTS

Fifty studies met inclusion criteria. In patients with breast, colorectal, and lung cancer, pain was not a significant prognostic factor for OS on multivariate analysis in most studies. In contrast, several studies suggest that pain is an independent prognostic factor for OS in advanced prostate cancer, even when relevant clinical prognostic variables are included. However, analgesic use was often used as a surrogate for prostate cancer pain, making it difficult to determine whether pain or opioid exposure was more important in influencing survival.

CONCLUSIONS

Pain may be associated with shorter survival in patients with cancer, but the mechanism for this relationship is unknown. The available evidence is insufficient to definitively determine if pain independently influences survival in patients with breast, colorectal, or lung cancer. The majority of studies in prostate cancer show pain to be an independent prognostic factor for OS, and often also incorporate opioid analgesic use in multivariate analysis. Prospective studies are needed to better understand how opioid utilization and pain may affect cancer progression and survival in diverse malignancies.

Prognostic significance of baseline fatigue for overall survival: A patient-level meta-analysis of 43 oncology clinical trials with 3915 patients

We have previously identified a single-item measure for baseline overall quality of life (QOL) as a strong prognostic factor for survival, and that fatigue was an important component of patient QOL. To explore whether patient-reported fatigue was supplemental or redundant to the prognostic information of overall QOL, we performed a patient-level pooled analysis of 43 North Central Cancer Treatment Group (NCCTG) and Mayo Clinic Cancer Center (MCCC) oncology clinical trials assessing the effect of baseline fatigue on overall survival (OS). 3,915 patients participating in 43 trials provided data at baseline for fatigue on a single-item 0-100 point scale. OS was tested for association with clinically deficient fatigue (CDF, score 0-50, n = 1,497) versus not clinically deficient fatigue (nCDF, score 51-100, n = 2,418). We explored whether fatigue contributed to overall survival in the presence of performance status and overall QOL. We used Cox proportional hazards models that adjusted for the effects of overall QOL, performance score, race, disease site, age and gender. Baseline fatigue was a strong predictor of OS for the entire patient cohort (CDF vs. nCDF: 31.5 months vs > 83.9 months, p < 0.0001). The effect sizes of fatigue on survival were more variable across different disease sites than was seen for overall QOL (GI, esophageal, head and neck, prostate, lung, breast and others). After controlling for covariates, including performance status and overall QOL, baseline fatigue remained a strong prognostic factor in multivariate models (CDF vs. nCDF: HR = 1.23, p = 0.02). Baseline fatigue is a strong and independent prognostic factor for OS over and above performance status (PS) and overall QOL in a wide variety of oncology patient populations. Single-item measures of overall QOL and fatigue can help to identify vulnerable subpopulations among cancer patients. We recommend these single-item measures for routine inclusion as a stratification factor or key covariate in the design and analysis of oncology treatment trials.

Symptom clusters and survival in Portuguese patients with advanced cancer

This study aimed to identify clusters of symptoms, to determine the patient characteristics associated with identified, and determine their strength of association with survival in patients with advanced cancer (ACPs). Consecutively eligible ACPs not receiving cancer‐specific treatment, and referred to a Tertiary Palliative Care Clinic, were enrolled in a prospective cohort study. At first consultation, patients rated 9 symptoms through the Edmonton Symptom Assessment System (0–10 scale) and 10 others using a Likert scale (1–5). Principal component analysis was used in an exploratory factor analysis to identify. Of 318 ACPs, 301 met eligibility criteria with a median (range) age of 69 (37–94) years. Three SCs were identified: neuro‐psycho‐metabolic (NPM) (tiredness, lack of appetite, lack of well−being, dyspnea, depression, and anxiety); gastrointestinal (nausea, vomiting, constipation, hiccups, and dry mouth) and sleep impairment (insomnia and sleep disturbance). Exploratory factor analysis accounted for 40% of variance of observed variables in all SCs. Shorter survival was observed for patients with the NPM cluster (58 vs. 23, P < 0.001), as well as for patients with two or more SCs (45 vs. 21, P = 0.005). In a multivariable model for survival at 30‐days, age (HR: 0.98; 95% CI: 0.97–0.99; P = 0.008), hospitalization at inclusion (HR: 2.27; 95% CI: 1.47–3.51; P < 0.001), poorer performance status (HR: 1.90, 95% CI: 1.24–2.89; P = 0.003), and NPM (HR: 1.64; 95% CI: 1.17–2.31; P = 0.005), were associated with worse survival. Three clinically meaningful SC in patients with advanced cancer were identifiable. The NPM cluster and the presence of two or more SCs, had prognostic value in relation to survival.

Symptom burden in lung cancer: management updates

Lung cancer is recognized to carry a high symptom burden with associated lowered quality of life as compared with other cancers. Research has shown that symptom severity can be a prognostic indicator of poorer clinical outcomes and survival post treatment. The purpose of this paper is to review current literature relative to symptom burden associated with diagnosis, medical and/or surgical intervention, assessment and management updates, and emerging initiatives that promote positive outcomes based on updated evidence. Discussion relative to interdisciplinary coordination of supportive services and palliative care initiation is provided.

Patient-reported physical functioning predicts the success of hematopoietic cell transplantation (BMT CTN 0902)

BACKGROUND

In hematopoietic cell transplantation (HCT), current risk adjustment strategies are based on clinical and disease-related variables. Although patient-reported outcomes (PROs) predict mortality in multiple cancers, they have been less well studied within HCT. Improvements in risk adjustment strategies in HCT would inform patient selection, patient counseling, and quality reporting. The objective of the current study was to determine whether pre-HCT PROs, in particular physical health, predict survival among patients undergoing autologous or allogeneic transplantation.

METHODS

In this secondary analysis, the authors studied pre-HCT PROs that were reported by 336 allogeneic and 310 autologous HCT recipients enrolled in the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0902 protocol, a study with broad representation of patients who underwent transplantation in the United States.

RESULTS

Among allogeneic HCT recipients, the pre-HCT Medical Outcomes Study Short Form-36 Health Survey (SF-36) physical component summary (PCS) scale independently predicted overall mortality (hazards ratio, 1.40 per 10-point decrease; P<.001) and performed at least as well as currently used, non-PRO risk indices. Survival probability estimates at 1 year for the first, second, third, and fourth quartiles of the baseline PCS were 50%, 65%, 75%, and 83%, respectively. Early post-HCT decreases in PCS were associated with higher overall and treatment-related mortality. When adjusted for patient variables included in the US Stem Cell Therapeutic Outcomes Database model for transplant center-specific reporting, the SF-36 PCS retained independent prognostic value.

CONCLUSIONS

PROs have the potential to improve prognostication in HCT. The authors recommend the routine collection of PROs before HCT, and consideration of the incorporation of PROs into risk adjustment for quality reporting.

Support for Patients and Family Caregivers in Lung Cancer: Educational Components of an Interdisciplinary Palliative Care Intervention

Consistent with the recommendations of the Institute of Medicine Report on quality cancer care, attention to symptom management and quality of life concerns of patients with lung cancer should be addressed throughout the disease trajectory. As part of a NCI-funded Program Project grant, this paper reports on the patient and family caregiver education component of a nurse-lead, tailored palliative care intervention for patients with early (I-III, n=130) and late (IV, n=142) stage lung cancer. Patients and family caregivers received 4 separate educational sessions organized around the Quality of Life model domains (physical, psychological, social, and spiritual well-being). Each patient and caregiver was presented at a weekly interdisciplinary case conference which also informed the educational sessions. Based on needs and team suggestions, an individualized palliative care plan was created and a tailored educational intervention was designed based on topics chosen by each participant. The most common topics chosen by patients in each domain were fatigue, worry and fear, social support/isolation, and hope. Family caregivers most commonly chose fatigue, worry and fear, communication, and purpose and meaning in life. The mean time spent in each teaching session ranged from 31 to 44 minutes for patients and 25 to 35 minutes for family caregivers. There is a vital need for interdisciplinary palliative care interventions for patients across all stages and across the disease trajectory. Nurses are vital to integrating palliative care into routine care. Providing a tailored educational intervention is an important aspect of palliative care for patients and family caregivers. This paper focuses on the process of the tailored educational intervention.

A comprehensive review of nongenetic prognostic and predictive factors influencing the heterogeneity of outcomes in advanced non-small-cell lung cancer

While there have been advances in treatment options for those with advanced non-small-cell lung cancer, unmet medical needs remain, partly due to the heterogeneity of treatment effect observed among patients. The goals of this literature review were to provide updated information to complement past reviews and to identify a comprehensive set of nongenetic prognostic and predictive baseline factors that may account for heterogeneity of outcomes in advanced non-small-cell lung cancer. A review of the literature between 2000 and 2010 was performed using PubMed, Embase, and Cochrane Library. All relevant studies that met the inclusion criteria were selected and data elements were abstracted. A classification system was developed to evaluate the level of evidence for each study. A total of 54 studies were selected for inclusion. Patient-related factors (eg, performance status, sex, and age) were the most extensively researched nongenetic prognostic factors, followed by disease stage and histology. Moderately researched prognostic factors were weight-related variables and number or site of metastases, and the least studied were comorbidities, previous therapy, smoking status, hemoglobin level, and health-related quality of life/symptom severity. The prognostic factors with the most consistently demonstrated associations with outcomes were performance status, number or site of metastases, previous therapy, smoking status, and health-related quality of life. Of the small number of studies that assessed predictive factors, those that were found to be significantly predictive of outcomes were performance status, age, disease stage, previous therapy, race, smoking status, sex, and histology. These results provide a comprehensive overview of nongenetic prognostic and predictive factors assessed in advanced non-small-cell lung cancer over the last decade. This information can be used to inform the design of future clinical trials by suggesting additional subgroups based on nongenetic factors that may be analyzed to further investigate potential prognostic and predictive factors.

Family caregiver burden, skills preparedness, and quality of life in non-small cell lung cancer

PURPOSE/OBJECTIVES

To describe burden, skills preparedness, and quality of life (QOL) for caregivers of patients with non-small cell lung cancer (NSCLC), and describe how the findings informed the development of a caregiver palliative care intervention that aims to reduce caregiver burden, improve caregiving skills, and promote self-care.

DESIGN

Descriptive, longitudinal.

SETTING

A National Cancer Institute-designated comprehensive cancer center in southern California.

SAMPLE

163 family members or friends aged 18 years or older and identified by patients as being a caregiver.

METHODS

All eligible caregivers were approached by advanced practice nurses during a regularly scheduled patient clinic visit. Informed consent was obtained prior to study participation. Outcome measures were completed at baseline and repeated at 7, 12, 18, and 24 weeks. Descriptive statistics were computed for all variables, and one-way repeated-measures analysis of variance was used to test for change over time for all predictor and outcome variables.

MAIN RESEARCH VARIABLES

Caregiver burden, skills preparedness, psychological distress, and QOL.

FINDINGS

Caregivers were highly functional. Caregiver burden related to subjective demands increased significantly over time. Perceived skills preparedness was high at baseline but decreased over time. Psychological distress was moderate but increased in the study period. Overall QOL was moderate at baseline and decreased significantly over time. Psychological well-being had the worst QOL score.

CONCLUSIONS

Caregivers experienced high levels of caregiver burden and reported deteriorations in psychological well-being and overall QOL.

IMPLICATIONS FOR NURSING

Oncology nurses need to ensure that caregivers receive information that supports the caregiving role throughout the cancer trajectory.

KNOWLEDGE TRANSLATION

Although family caregivers are profoundly impacted by a loved one's lung cancer diagnosis, the literature about caregiver burden, skills preparedness, and QOL is limited. Current evidence suggests that family caregivers can be negatively impacted by a loved one's cancer diagnosis. Caregiver-specific support interventions are needed to eliminate the burden of caregiving in lung cancer.

Prognostic value of patient-reported symptom interference in patients with late-stage lung cancer

PURPOSE

Patient-reported outcomes (PROs) have been found to be significant predictors of clinical outcomes such as overall survival (OS), but the effect of demographic and clinical factors on the prognostic ability of PROs is less understood. Several PROs derived from the 12-item Short-Form Health Survey (SF-12) and M. D. Anderson Symptom Inventory (MDASI) were investigated for association with OS, with adjustments for other factors, including performance status.

METHODS

A retrospective analysis was performed on data from 90 patients with stage IV non-small cell lung cancer. Several baseline PROs were added to a base Cox proportional hazards model to examine the marginal significance and improvement in model fit attributable to the PRO: mean MDASI symptom interference level; mean MDASI symptom severity level for five selected symptoms; SF-12 physical and mental component summaries; and the SF-12 general health item. Bootstrap resampling was used to assess the robustness of the findings.

RESULTS

The MDASI mean interference level had a significant effect on OS (p = 0.007) when the model was not adjusted for interactions with other prognostic factors. Further exploration suggested the significance was due to an interaction with performance status (p = 0.001). The MDASI mean symptom severity level and the SF-12 physical component summary, mental component summary, and general health item did not have a significant effect on OS.

CONCLUSIONS

Symptom interference adds prognostic information for OS in advanced lung cancer patients with poor performance status, even when demographic and clinical prognostic factors are accounted for.

Interdisciplinary palliative care intervention in metastatic non-small-cell lung cancer

OBJECTIVE

Challenges and barriers continue to hinder the integration of palliative care models into comprehensive, ambulatory oncology care. This article aims to describe how symptoms, distress, and quality of life (QOL) data from the usual care phase of a National Cancer Institute-supported Program Project informed the development of an interdisciplinary, tailored palliative care intervention for patients with metastatic non-small-cell lung cancer (NSCLC).

METHODS

Patients receiving usual care for metastatic NSCLC were recruited into this prospective longitudinal study over a 1-year period. A total of 130 patients with stage IV NSCLC were accrued, and 114 patients had evaluable data. Research nurses assisted patients in completing the clinical section of the data forms, and patients completed surveys and self-reports at baseline and 6, 12, and 24 weeks.

RESULTS

Patients ranged in age from 40 to 84 years, and 61% were Caucasian non-Hispanic. Sixty-six former (N = 59) and current smokers had an average of 38 pack-year history of smoking. The Karnofsky Performance Status, Instrumental Activities of Daily Living, and Cognitive scores deteriorated significantly (P = .001, .009, and .042, respectively). Social Activity was stable, whereas Social Support increased significantly. Overall symptom distress score and Total symptom score both significantly increased at 24 weeks (P = .003 and .017, respectively). Physical Well-Being decreased significantly (P = .036), whereas the Functional Assessment of Cancer Therapy-Lung, Functional Assessment of Chronic Illness Therapy-Spirituality Subscale, and Distress scores remained statistically stable over time.

CONCLUSIONS

Patients with metastatic NSCLC continue to experience high symptom burden and diminished physical well-being over time while receiving cancer treatments. An interdisciplinary palliative care intervention is currently being tested to improve symptom burden and overall QOL.

Longitudinal changes in function, symptom burden, and quality of life in patients with early-stage lung cancer

BACKGROUND

Emerging evidence supports the integration of palliative care concurrently with disease-focused care in patients with serious illnesses, such as lung cancer. This paper describes how longitudinal changes in physical function, symptom burden, and QOL of patients with early-stage non-small cell lung cancer (NSCLC) informed the development of an interdisciplinary, tailored palliative care intervention.

METHODS

Patients with early stage (I-IIIB) NSCLC were accrued into the usual care phase (Phase 1) of an NCI-funded Program Project Grant. Baseline and longitudinal (up to 52 weeks post-accrual) physical function, symptoms, and QOL were assessed in the thoracic ambulatory clinics of one NCI-designated Comprehensive Cancer Center. Outcome measures included geriatric assessments, psychological distress, symptoms, and QOL. The association between disease stage (I-II vs. III) and longitudinal changes in these domains was evaluated.

RESULTS

A total of 103 patients were accrued. Stage I-II patients were significantly more likely to complete the study (p = 0.005). The stages (I-II vs. III) were equivalent at baseline on all demographic variables, clinical, and functional status. Physical function fluctuated longitudinally and was higher at 6 and 24 weeks than at baseline and 12 weeks. There was a longitudinal decrease in total number of symptoms (p < 0.001). Physical and social/family QOL fluctuated longitudinally (p < 0.001 and p = 0.016, respectively).

CONCLUSIONS

Patients with early-stage NSCLC report a significant longitudinal decrease in physical QOL, and fluctuations in objective and subjective measures of physical function over time were observed regardless of disease stage category. An interdisciplinary palliative care intervention is currently being tested to decrease symptom burden and improve QOL.

Changes in pain and other symptoms in patients with painful multiple myeloma-related vertebral fracture treated with kyphoplasty or vertebroplasty

Patients with painful vertebral compression fractures produced by multiple myeloma (MM) often experience reduction in pain after spinal augmentation with kyphoplasty or vertebroplasty. Previous studies have shown pain reduction and improvement in functional status after augmentation, but no studies have examined the effect of augmentation on other cancer-related symptoms. We hypothesized that reduction in pain severity would be significantly associated with improvement in other reported symptoms. We retrospectively studied 79 patients who rated pain and symptom severity both before and after kyphoplasty or vertebroplasty. Pain was significantly reduced after spinal augmentation (1.3 on a 0 to 10 scale; effect size [ES] = .59; P < .001), as were anxiety (1.3; ES = .47), drowsiness (1.3; ES = .39), fatigue (1.1; ES = .32), depression (.7; ES = .28), and difficulty thinking clearly (.7; ES = .26) (all P < .05). Greater reduction in pain was associated with a greater number of symptoms being reduced. Interestingly, insomnia worsened regardless of any amount of improvement in pain. Because appropriate symptom control contributes to the overall well-being of cancer patients, future studies of pain reduction procedures should include measures of other symptoms to fully characterize the potential benefit of treating pain.

PERSPECTIVE

Appropriate symptom control contributes to overall well-being for cancer patients. This study demonstrated that pain reduction after spinal augmentation with vertebroplasty or kyphoplasty was positively associated with reduction in other patient-reported cancer-related symptoms. Future studies of these augmentation procedures should measure multiple symptoms, in addition to pain and functional status.

Levels of symptom burden during chemotherapy for advanced lung cancer: differences between public hospitals and a tertiary cancer center

PURPOSE

We compared risk factors for high disease- and treatment-related symptom burden over 15 weeks of therapy in medically underserved patients with advanced non-small-cell lung cancer and in patients treated at a tertiary cancer center.

PATIENTS AND METHODS

We monitored symptom severity weekly during chemotherapy. Patients were recruited from a tertiary cancer center (n=101) and three public hospitals treating the medically underserved (n=80). We used a composite symptom-severity score and group-based trajectory analysis to form two groups: one with consistently more severe symptoms and another with less severe symptoms. We examined predictors of group membership.

RESULTS

Seventy percent of the sample (n=126) reported low symptom-severity levels that decreased during therapy; 30% (n=55) had consistently severe symptoms throughout the study. In multivariate analysis, patients with good performance status being treated in public hospitals were significantly more likely than patients treated at the tertiary cancer center to be in the high-symptom group (odds ratio, 5.6; 95% CI, 2.1 to 14.6; P = .001) and to report significantly higher symptom interference (P = .001). Other univariate predictors of high-symptom group membership included variables associated with being medically underserved (eg, having less education, being single, and being nonwhite). No group differences by ethnicity were observed in the public hospitals. Medically underserved patients were less likely to receive adequate pain management.

CONCLUSION

Patients with advanced lung cancer and good performance status treated at public hospitals were more likely than those treated at a tertiary cancer center to experience substantial symptoms during chemotherapy.

Measuring the symptom burden of lung cancer: the validity and utility of the lung cancer module of the M. D. Anderson Symptom Inventory

We conducted a study to establish the psychometric properties of a module of the M. D. Anderson Symptom Inventory (MDASI) developed specifically for patients with lung cancer (MDASI-LC). The MDASI measures 13 common "core" symptoms of cancer and its treatment. The MDASI-LC includes the 13 core MDASI symptom items and three lung cancer-specific items: coughing, constipation, and sore throat. MDASI-LC items were administered to three cohorts of patients with lung cancer undergoing either chemotherapy or chemoradiotherapy. Known-group validity and criterion (concurrent) validity of the MDASI-LC were evaluated using the Eastern Cooperative Oncology Group performance status and the 12-item Short-Form Health Survey. The internal consistency and test-retest reliability of the module were adequate, with Cronbach coefficient α-values of 0.83 or higher for all module items and subscales. The sensitivity of the MDASI-LC to changes in patient performance status (disease progression) and to continuing cancer treatment (effects of treatment) was established. Cognitive debriefing of a subset of participants provided evidence for content validity and indicated that the MDASI core items and three additional lung cancer-specific items were clear, relevant to patients, and easy to understand; only two patients suggested additional symptom items. As expected, the item "sore throat" was sensitive only for patients receiving chemoradiotherapy. The MDASI-LC is a valid, reliable, and sensitive symptom-assessment instrument whose use can enhance clinical studies of symptom status in patients with lung cancer and epidemiological and prevalence studies of symptom severity across various cancer types.
