Disease and treatment characteristics do not predict symptom occurrence profiles in oncology outpatients receiving chemotherapy (original) (raw)

Patient factors and quality of life outcomes differ among four subgroups of oncology patients based on symptom occurrence

Acta oncologica (Stockholm, Sweden), 2017

Reviews of the literature on symptoms in oncology patients undergoing curative treatment, as well as patients receiving palliative care, suggest that they experience multiple, co-occurring symptoms and side effects. The purposes of this study were to determine if subgroups of oncology patients could be identified based on symptom occurrence rates and if these subgroups differed on a number of demographic and clinical characteristics, as well as on quality of life (QoL) outcomes. Latent class analysis (LCA) was used to identify subgroups (i.e. latent classes) of patients with distinct symptom experiences based on the occurrence rates for the 13 most common symptoms from the Memorial Symptom Assessment Scale. In total, 534 patients with breast, head and neck, colorectal, or ovarian cancer participated. Four latent classes of patients were identified based on probability of symptom occurrence: all low class [i.e. low probability for all symptoms (n = 152)], all high class (n = 149), hi...

The symptom phenotype of oncology outpatients remains relatively stable from prior to through 1 week following chemotherapy

European journal of cancer care, 2016

Some oncology outpatients experience a higher number of and more severe symptoms during chemotherapy (CTX). However, little is known about whether this high risk phenotype persists over time. Latent transition analysis (LTA) was used to examine the probability that patients remained in the same symptom class when assessed prior to the administration of and following their next dose of CTX. For the patients whose class membership remained consistent, differences in demographic and clinical characteristics, and quality of life (QOL) were evaluated. The Memorial Symptom Assessment Scale (MSAS) was used to evaluate symptom burden. LTA was used to identify subgroups of patients with distinct symptom experiences based on the occurrence of the MSAS symptoms. Of the 906 patients evaluated, 83.9% were classified in the same symptom occurrence class at both assessments. Of these 760 patients, 25.0% were classified as Low-Low, 44.1% as Moderate-Moderate and 30.9% as High-High. Compared to the ...

Comparison of subgroups of breast cancer patients on pain and co-occurring symptoms following chemotherapy

Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2015

The purposes of this study, in a sample of women with breast cancer receiving chemotherapy (CTX), were to identify subgroups of women with distinct experiences with the symptom cluster of pain, fatigue, sleep disturbance, and depressive symptoms and evaluate differences in demographic and clinical characteristics, differences in psychological symptoms, and differences in pain characteristics among these subgroups. Patients completed symptom questionnaires in the week following CTX administration. Latent class profile analysis (LCPA) was used to determine the patient subgroups. Three subgroups were identified: 140 patients (35.8 %) in the "low," 189 patients (48.3 %) in the "moderate," and 62 patients (15.9 %) in the "all…

A literature synthesis of symptom prevalence and severity in persons receiving active cancer treatment

Supportive Care in Cancer, 2013

Purpose Patients with cancer experience acute and chronic symptoms caused by their underlying disease or by the treatment. While numerous studies have examined the impact of various treatments on symptoms experienced by cancer patients, there are inconsistencies regarding the symptoms measured and reported in treatment trials. This article presents a systematic review of the research literature of the prevalence and severity of symptoms in patients undergoing cancer treatment. Methods A systematic search for studies of persons receiving active cancer treatment was performed with the search terms of "multiple symptoms" and "cancer" for studies involving patients over the age of 18 years and published in English during the years 2001 to 2011. Search outputs were reviewed independently by seven authors, resulting in the synthesis of 21 studies meeting criteria for generation of an Evidence Table reporting symptom prevalence and severity ratings. Results Data were extracted from 21 multinational studies to develop a pooled sample of 4,067 cancer patients in whom the prevalence and severity of individual symptoms was reported. In total, the pooled sample across the 21 studies was comprised of 62 % female, with a mean age of 58 years (range 18 to 97 years). A majority (62 %) of these studies assessed symptoms in homogeneous samples with respect to tumor site (predominantly breast and lung cancer), while 38 % of the included studies utilized samples with mixed diagnoses and treatment regimens. Eighteen instruments and structured interviews were including those measuring single symptoms, multisymptom inventories, and single symptom items drawn from HRQOL or health status measures. The MD Anderson Symptom Inventory was the most commonly used instrument in the studies analyzed (n=9 studies; 43 %), while the Functional Assessment of Cancer Therapy, Hospital Anxiety and Depression Subscale, Medical Outcomes Survey Short Form-36, and Symptom Distress Scale were each employed in two studies. Forty-seven symptoms were identified across the 21 studies which were then categorized into 17 logical groupings. Symptom prevalence and severity were calculated across the entire cohort and also based upon sample sizes in which the symptoms were measured providing the ability to rank symptoms. Conclusions Symptoms are prevalent and severe among patients with cancer. Therefore, any clinical study seeking to evaluate the impact of treatment on patients should consider including measurement of symptoms. This study demonstrates that a discrete set of symptoms is common across cancer types. This set may serve as the basis for defining a "core" set of

The Symptom Experience of Oncology Outpatients Has a Different Impact on Quality-of-Life Outcomes

Journal of Pain and Symptom Management, 2008

The aims of this replication study were to determine if subgroups of oncology outpatients receiving active treatment could be identified based on their experience with the symptoms of fatigue, sleep disturbance, depression, and pain; whether patients in these subgroups differed on selected demographic, disease, and treatment characteristics; and if patients in these subgroups differed on functional status and quality of life (QOL). A convenience sample of 228 oncology outpatients was recruited from seven outpatient settings in Israel. Patients completed a demographic questionnaire, a Karnofsky Performance Status score, the Multidimensional Quality of Life Scale—Cancer, the Lee Fatigue Scale, the General Sleep Disturbance Scale, the Center for Epidemiological Studies—Depression Scale, and a numeric rating scale of worst pain intensity. Cluster analysis was used to identify the patient subgroups based on their symptom experience. Four relatively distinct patient subgroups were identified based on their experiences with the above symptoms (i.e., low levels of all four symptoms (32.9%), low levels of pain and high levels of fatigue (18.0%), high levels of pain and moderate levels of fatigue (42.5%), and high levels of all four symptoms (6.6%). No differences were found among the four subgroups on any demographic, disease, or treatment characteristics. The subgroup of patients who reported high levels of all four symptoms reported the worst functional status and poorest QOL. In conclusion, differences in the symptom experience of oncology outpatients suggest that patients may harbor different phenotypic characteristics (e.g., environmental or physiologic) or genetic determinants for experiencing symptoms that are independent of demographic, disease, and treatment characteristics.

Cancer-related symptom clusters for symptom management in outpatients after commencing adjuvant chemotherapy, at 6 months, and 12 months

Supportive Care in Cancer, 2011

Goals of work The aim of this secondary data analysis was to investigate symptom clusters over time for symptom management of a patient group after commencing adjuvant chemotherapy. Materials and methods A prospective longitudinal study of 219 cancer outpatients conducted within 1 month of commencing chemotherapy (T1), 6 months (T2), and 12 months (T3) later. Patients' distress levels were assessed for 42 physical symptoms on a clinician-modified Rotterdam Symptom Checklist. Symptom clusters were identified in exploratory factor analyses at each time. Symptom inclusion in clusters was determined from structure coefficients. Symptoms could be associated with multiple clusters. Stability over time was determined from symptom cluster composition and the proportion of symptoms in the initial symptom clusters replicated at later times. Main results Fatigue and daytime sleepiness were the most prevalent distressing symptoms over time. The median number of concurrent distressing symptoms approximated 7, over time. Five consistent clusters were identified at T1, T2, and T3. An additional two clusters were identified at 12 months, possibly due to less variation in distress levels. Weakness and fatigue were each associated with 2, 4, and 5 symptom clusters at T1, T2, and T3, respectively, potentially suggesting different causal mechanisms. Conclusion Stability is a necessary attribute of symptom clusters, but definitional clarification is required. We propose a core set of concurrent symptoms identifies each symptom cluster, signifying a common cause. Additional related symptoms may be included over time. Further longitudinal investigation is required to identify symptom clusters and the underlying causes.

Symptom Assessment among Cancer Patients Receiving Chemotherapy In A Cancer Hospital

Tribhuvan University Journal

People with cancer usually experience various distressing symptoms while receiving chemotherapy. Early identification of distressing symptoms of patients receiving treatment is a crucial step toward providing quality nursing care for patients. This study aimed to assess the frequency, severity and distressing symptoms and its predictors among cancer patients who are receiving chemotherapy. An Analytical cross-sectional study was done among 233 people receiving cancer chemotherapy in a Cancer Hospital. Convenience sampling method was adopted to select sample and data was collected by in-person interview. Out of 233 respondents, less than half(42.6%) belonged to the 40-59 years age group and male (53.6%). The common physical symptoms were pain (70%), lack of energy (67.8%), nausea (58.8%) and psychological symptoms were feeling sad (43.8%), worrying (43.8%) and difficulty sleeping (18.5%). The most severe symptoms experienced by respondents were pain, dry mouth, lack of energy and sho...

Stability of Symptom Clusters in Patients with Breast Cancer Receiving Chemotherapy

Journal of pain and symptom management, 2017

Patients with breast cancer who undergo chemotherapy (CTX) experience between 10 and 32 concurrent symptoms. An evaluation of how these symptoms cluster together and how these symptom clusters change over time may provide insights into how to treat these multiple co-occurring symptoms. The purposes of this study were to: determine the occurrence rates and severity ratings for 38 common symptoms, evaluate for differences in the number and types of symptom clusters, and evaluate for changes over time in these symptom clusters (i.e., prior to CTX, the week following CTX, and two weeks following CTX). At each of the assessments, a modified version of the Memorial Symptom Assessment Scale was used to assess the occurrence and severity of the 38 symptoms. Exploratory factor analyses were used to extract the symptom clusters. While across the two symptom dimensions (i.e., occurrence, severity) and the three assessments, eight distinct symptom clusters were identified, only five were relati...

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

Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2017

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. 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. 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. S...
