Symptoms during chemotherapy in colorectal cancer patients

Role of Gender and Race in Patient-Reported Outcomes and Satisfaction

Patient-reported outcomes and patient-reported outcome measures are important tools that pertain to a patient's health, quality of life, or functional status associated with clinical care. There are multiple measurement tools available to measure these outcomes. Recently, there has been an increased focus on understanding the role of demographic determinants such as gender, race and socioeconomic status (SES) on patient reported outcomes. Therefore, in this review, outcome domain tools to measure these domains and the roles of gender, race, and SES on outcomes are analyzed.

Impact of Multimorbidity on Symptom Burden and Symptom Clusters in Patients Receiving Chemotherapy

BACKGROUND

Detailed information on patient characteristics and symptom burden associated with multimorbidity in oncology patients is extremely limited. Purposes were to determine the prevalence of low (≤ 2) and high (≥ 3) multimorbidity in a sample of oncology outpatients (n = 1343) undergoing chemotherapy and evaluate for differences between the two multimorbidity groups in demographic and clinical characteristics; the occurrence, severity, and distress of 38 symptoms; and the stability and consistency of symptom clusters.

METHODS

Using the Self-Administered Comorbidity Questionnaire, patients were classified into low and high multimorbidity groups. Memorial Symptom Assessment Scale was used to assess the occurrence, severity, and distress of 38 symptoms prior to the patients' second or third cycle of chemotherapy. For each multimorbidity group, symptom clusters based on occurrence rates were identified using exploratory factor analysis.

RESULTS

Compared to the low group (61.4%), patients in the high group (38.6%) were older, had fewer years of education, were less likely to be married or partnered, less likely to be employed, and had a lower annual income. In addition, they had a higher body mass index, poorer functional status, were a longer time since their cancer diagnosis, and were more likely to have received previous cancer treatments and have metastatic disease. Patients in the low and high groups reported 12.7 (±6.7) and 15.9 (±7.5) concurrent symptoms, respectively. Eight and seven symptom clusters were identified for the low and high groups, respectively. Psychological, gastrointestinal, weight gain, hormonal, and respiratory clusters were stable across multimorbidity groups. Weight gain and respiratory clusters were consistent. Three unstable clusters were identified in the low group and two in the high group.

CONCLUSIONS

Findings suggest that higher multimorbidity is associated with various social determinants of health and a higher symptom burden. Differences between multimorbidity groups may be related to aging, treatments, and/or comorbid conditions.

Exercise and Nutrition to Improve Cancer Treatment-Related Outcomes (ENICTO)

Chemotherapy treatment-related side effects are common and increase the risk of suboptimal outcomes. Exercise interventions during cancer treatment improve self-reported physical functioning, fatigue, anxiety, and depression, but it is unclear whether these interventions improve important clinical outcomes, such as chemotherapy relative dose intensity. The National Cancer Institute funded the Exercise and Nutrition to Improve Cancer Treatment-Related Outcomes (ENICTO) Consortium to address this knowledge gap. This article describes the mechanisms hypothesized to underpin intervention effects on clinically relevant treatment outcomes, briefly outlines each project's distinct research aims, summarizes the scope and organizational structure of ENICTO, and provides an overview of the integrated common data elements used to pursue research questions collectively. In addition, the article includes a description of consortium-wide activities and broader research community opportunities for collaborative research. Findings from the ENICTO Consortium have the potential to accelerate a paradigm shift in oncology care such that patients with cancer could receive exercise and nutrition programming as the standard of care in tandem with chemotherapy to improve relative dose intensity for a curative outcome.

Impact on survival benefits of asymptomatic primary tumor resection after bevacizumab plus FOLFIRI as first-line therapy for patients with metastatic colorectal cancer with synchronous unresectable metastasis

BACKGROUND

Metastatic colorectal cancer (mCRC) poses a clinical challenge and requires a combination of systemic therapy and conversion surgery. Although first-line chemotherapy and targeted therapy are considered the standard treatments for mCRC, the role of primary tumor resection (PTR) in asymptomatic synchronous mCRC with unresectable metastatic lesion after initial therapy remains relatively underexplored.

MATERIALS

A retrospective review was conducted from January 2015 to January 2021, involving 74 patients with synchronous mCRC who received bevacizumab plus FOFIRI as first-line systemic therapy. All 74 patients had unresectable metastatic lesions confirmed through multidisciplinary team discussion. Patient characteristics, PTR data, and radiotherapy (RT) and overall survival (OS) outcomes were analyzed. The patients were categorized into a "PTR" group and a "No PTR" group and then further stratified into "4A," "4B," and "4C" subgroups based on the initial mCRC stage. Additionally, four subgroups-namely "PTR( +)/RT( +)," "PTR( +)/RT( -)," "PTR( -)/RT( +)," and "PTR( -)/RT( -)"-were formed to assess the combined effects of PTR and RT.

RESULTS

The median OS for all the patients was 23.8 months (20.5-27.1 months). The "PTR" group exhibited a significantly higher median OS of 25.9 months (21.3-30.5 months) compared with 21.4 months (15.8-27.1 months) in the "No PTR" group (p = 0.048). Subgroup analyses revealed a trend of improved survival with PTR in patients with stage IVA and IVB; however, the results were not statistically significant (p = 0.116 and 0.493, respectively). A subgroup analysis of PTR and RT combinations revealed no significant difference in median OS rates.

CONCLUSION

For asymptomatic mCRC with synchronous unresectable distant metastasis, PTR following first-line therapy with bevacizumab plus FOLFIRI may provide a potential survival benefit, particularly in stage IVA/IVB patients compared with stage IVC patients. Additionally, RT for primary tumor did not provide an additional OS benefit in mCRC with unresectable metastasis. A prospective randomized trial with a larger sample size is essential to further elucidate the role of PTR in this context.

Supportive care needs, quality of life and social support among elderly colorectal cancer patients undergoing chemotherapy: a longitudinal study

Objective

The purpose of this study is to examine the changes in supportive care needs, quality of life and social support during different chemotherapy cycles among elderly colorectal cancer patients.

Methods

This prospective longitudinal study recruited 160 elderly colorectal cancer patients using convenience sampling at a hospital in Guangxi between August 2023 and April 2024. To assess supportive care needs, quality of life, and social support, we used a short form of the Supportive Care Needs Survey (SCNS-SF34), a Functional Assessment of Cancer Therapy-colorectal (FACT-C), and a perceived social support scale (PSSS) prior to chemotherapy, as well as after the first, third, and sixth cycles. Repeated measures analysis of variance was used to validate the changes over time in supportive care needs, quality of life, and social support.

Results

155 participants completed all questionnaire sessions across the six cycles. From pre-chemotherapy until after the sixth cycle of chemotherapy, the extent of physical and daily living requirements among all respondents fluctuated between 47.23% and 88.26%, psychological needs ranged from 60.84% to 97.67%, patient care and support needs ranged from 83.75% to 99.35%, healthcare system and information needs varied from 85.98% to 99.00%, while the level of sexual needs decreased from 1.51% to 0.65%. The mean SCNS-SF34 scores for these participants ranged between 103.81 ± 2.28 and 144.10 ± 1.08. Significant increases over time were seen for all domains of SCNS-SF34 (F=126.99, 347.41, 65.00, 72.34, 160.15, p<0.001), keeping a clear upward trend, except for sexual needs(F=0.712, p=0.546). The mean FACT-T scores dropped from 68.80 ± 1.00 to 51.24 ± 1.40, while the mean PSSS scores dropped from 55.77 ± 0.83 to 43.28 ± 1.05. The scores of FACT-T and PSSS showed statistically significant differences (F=231.21, 112.28, p<0.001), maintaining clear downward trends.

Conclusion

During chemotherapy, elderly colorectal cancer patients continue to require high levels of supportive care, while their quality of life and social support gradually decline. This study offers healthcare practitioners a foundational understanding to identify and address the supportive care needs of elderly colorectal cancer patients across various chemotherapy phases, which facilitates the development of tailored strategies aimed at enhancing patients' quality of life.

Advances in Adherence Reporting of Resistance Training in a Clinical Trial during Adjuvant Chemotherapy for Colon Cancer

PURPOSE

Detailed reporting of individually tailored exercise prescriptions (ExR x ) used in clinical trials is essential to describe feasibility, tolerability, and efficacy of the intervention and to inform translation to clinical care. This article outlines the methodology used to develop a resistance training (RT) ExR x for people with colon cancer receiving chemotherapy and reports adherence to the randomized controlled trial testing the impact of RT on relative dose intensity of chemotherapy and patient-reported toxicities.

METHODS

Participants randomized to the exercise arm ( n = 90) were included. To promote muscle hypertrophy, the ExR x was twice-weekly, moderate to heavy loads (65%-85% one-repetition maximum), high sets (3-5), and intermediate repetitions (6-10) of five large multijoint movements with adjustable dumbbells. Attendance (achieved frequency) and adherence (achieved volume) were calculated. Group-based trajectory modeling was used to identify clusters of individuals with similar adherence patterns and compared baseline characteristics across adherence groups.

RESULTS

The median attendance was 69.1%. Adherence was 60.6% but higher for those receiving 3 versus 6 months of chemotherapy (80.4 vs 47.4%; P < 0.05 ). Participants engaged in a median of 1.4 d of RT each week, lifting 62% of the one-repetition maximum load, for 3.0 sets and 7.5 repetitions per set. Three distinct adherence groups were identified: 13% "nonstarter," 37% "tapered off," and 50% "consistent exercisers." Females were more likely to be in the nonstarter and tapered-off groups.

CONCLUSIONS

This article outlines suggested methods for reporting ExR x of RT in oncology clinical trials and provides insight into the tolerance of ExR x of RT during chemotherapy treatment for colon cancer. These findings aim to foster constructive dialogue and offer a premise for designing future research to elucidate the benefits of exercise during chemotherapy.

Immunotherapy-induced colitis in metastatic colorectal cancer: a systematic review and meta-analysis

Colorectal cancer (CRC) presents significant mortality risks, underscoring the urgency of timely diagnosis and intervention. Advanced stages of CRC are managed through chemotherapy, targeted therapy, immunotherapy, radiotherapy, and surgery. Immunotherapy, while effective in bolstering the immune system against cancer cells, often carries toxic side effects, including colitis. This study aimed to evaluate the incidence of colitis in patients with metastatic CRC (mCRC) undergoing various immunotherapy treatments. Through a systematic search of Google Scholar and PubMed databases from inception until November 2023, nine relevant studies were identified. Subgroup analyses revealed a higher incidence of colitis, particularly in patients treated with anti-cytotoxic T-lymphocyte-associated molecule-4 (anti-CTLA-4) and combination therapies compared to monotherapy with programmed cell death receptor-1 (PD-1) or programmed cell death ligand receptor-1 (PDL-1) inhibitors. Notably, naive-treated metastatic CRC patients exhibited elevated colitis incidences compared to those previously treated. In conclusion, anti-CTLA-4 and combination therapies, such as nivolumab plus ipilimumab, were associated with increased colitis occurrences in metastatic CRC patients, highlighting the need for vigilant monitoring and management strategies, especially in immunotherapy-naive individuals.

Pairing automated exercise coaching with patient-reported symptom monitoring: A way to nudge exercise uptake during cancer treatment?

INTRODUCTION

Symptoms during cancer treatment cause burden, diminished physical functioning, and poor quality of life. Exercise is recommended during treatment to mitigate symptoms; however, interventions are difficult to translate into clinical care due to the lack of patient uptake and clinical implementation barriers. We evaluated the uptake, acceptability, and impact of an automated ePRO exercise module triggered by three patient-reported symptoms: nausea/vomiting, fatigue, and anxiety, during chemotherapy.

METHODS

We conducted a secondary analysis of an exercise module intervention imbedded in the cancer symptom monitoring and management platform, Symptom Care at Home (SCH). Utilizing behavioral economics principles, the exercise module was triggered when any of the three symptoms were reported. Once triggered, participants were coached on exercise benefits for symptom reduction and then offered the opportunity to set weekly exercise goals plus tracking of the goal outcomes and receive further encouragement. We examined uptake, exercise goal setting and attainment, and symptom impact.

RESULTS

Of 180 SCH participants receiving the SCH intervention, 170 (94.4%) triggered the exercise module and 102 of the 170 (60%) accepted the module, setting goals on average for 6.3 weeks. Of 102 participants, 82 (80.4%) achieved one or more exercise goals, exercising on average 79.8 min/week. Participants who achieved a higher proportion of goals had statistically significant lower overall symptom severity and lower severity of the triggered symptom.

CONCLUSION

An automated mHealth exercise coaching intervention, aimed to nudge those receiving chemotherapy to initiate an exercise routine had significant uptake, is acceptable and may reduce symptom severity.

Do older patients with colorectal cancer experience more deterioration in health-related quality of life than younger patients during the first year of palliative chemotherapy? A prospective real-world observational study

INTRODUCTION

The primary aim was to evaluate changes in health-related quality of life (HRQoL) in a real-life population among younger (< 70 years) and older patients with metastatic colorectal cancer (mCRC) during the first year of palliative chemotherapy. The secondary aims were to assess the impact of chemo-break on HRQoL and to report overall survival (OS).

MATERIALS AND METHODS

Patients with newly diagnosed mCRC, ≥ 18 years, and scheduled for first line palliative chemotherapy were included in this multicentre longitudinal observational study. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (0-100) was filled in at baseline and every second month. Changes or differences in QoL scores of >20, 10-20, and 5-10 points were considered to be of large, moderate, and small clinical magnitude, respectively. Comparing means of different QoL scores between groups or over time, a threshold of 5-10 was considered the minimally important difference (MID). Treatments, patient characteristics, and tumour characteristics were prospectively registered.

RESULTS

A total of 214 patients were included, and 146 were alive after one year. Four months after start of treatment, large deteriorations in fatigue and physical functioning were reported by 40% and 25% of the patients, respectively. Changes in global QoL, physical functioning, role functioning, fatigue, pain, and nausea/vomiting were not significantly different between the age groups and reached baseline levels after one year. Patients on chemo-break reported significant improvements in several HRQoL domains. Median OS was 17.5 months [95% confidence interval 14.4-20.5] with no difference between younger and older patients.

DISCUSSION

Older patients did not experience more deterioration in HRQoL than younger patients during the first year of palliative chemotherapy. Measures to mitigate the deteriorations in fatigue and physical functioning observed during the first months of palliative treatment are warranted.

Distinct morning and evening fatigue profiles in gastrointestinal cancer during chemotherapy

BACKGROUND

Purposes were to identify subgroups of patients with gastrointestinal cancers with distinct morning and evening fatigue severity profiles and evaluate for differences among these subgroups in demographic and clinical characteristics, co-occurring symptoms and quality of life (QOL) outcomes.

METHODS

Patients with gastrointestinal cancers (n=405) completed questionnaires six times over two cycles of chemotherapy. Latent profile analysis was used to identify distinct morning and evening fatigue profiles. Differences in demographic and clinical characteristics, co-occurring symptoms and QOL outcomes among the subgroups were evaluated using parametric and nonparametric tests.

RESULTS

Two distinct mornings (ie, low and very high) and three distinct evenings (ie, low, moderate and very high) fatigue classes were identified. Common risk factors for both morning and evening fatigue included younger age, lower performance status, higher comorbidity burden and self-reported depression. Higher levels of morning fatigue were associated with being unmarried, living alone, being unemployed, having a lower income, lack of regular exercise and a self-reported diagnosis of anaemia. Higher levels of evening fatigue were associated with being women, white and having childcare responsibilities. Patients in the very high morning and evening fatigue classes reported higher levels of anxiety, depressive symptoms, sleep disturbance and pain and lower levels of attentional function and poorer QOL.

CONCLUSION

Findings provide new insights into risk factors for and deleterious effects of morning and evening fatigue in patients with gastrointestinal cancers. Clinicians can use this information to identify high-risk patients and develop individualised interventions for morning and evening fatigue and other co-occurring symptoms.

The effect of nurse-led empowering education on nutrition impact side effects in patients with colorectal cancer undergoing chemotherapy: A randomised trial

OBJECTIVE

This study assessed the effect of empowering education on patient-reported outcomes and morbidity.

METHODS

A randomised controlled trial was conducted on adults with colorectal cancer (43 + 40). The intervention consisted of one-hour empowering patient education on nutrition impact side effects. The effect was compared with standard care. The difference between the groups was analysed pre and post intervention.

RESULTS

The change in malnutrition-related knowledge level was higher in the intervention group compared to control group (median 0.0, IQR 1.00 vs median 0.0, IQR 0.0, p = 0.028). Additional contacts with outpatient clinic were fewer in intervention group (median 0.00, IQR 0.00) compared to control group (median 1.00, IQR 2.00, p < 0.001). We did not find a statistically significant difference in the change in activation level, risk of malnutrition and quality of life between the groups.

CONCLUSION

Empowering education may affect positively on patients' knowledge level related to malnutrition and reduce the number of additional contacts with health care thus reduce health care costs.

PRACTICE IMPLICATIONS

Empowering education may be used in patients with colorectal cancer to improve knowledge and reduce additional contacts with health care. Further research is needed on the effect of empowering education in self-care.

Comparative Study of Nanoparticle Blood Circulation after Forced Clearance of Own Erythrocytes (Mononuclear Phagocyte System-Cytoblockade) or Administration of Cytotoxic Doxorubicin- or Clodronate-Loaded Liposomes

Recent developments in the field of nanomedicine have introduced a wide variety of nanomaterials that are capable of recognizing and killing tumor cells with increased specificity. A major limitation preventing the widespread introduction of nanomaterials into the clinical setting is their fast clearance from the bloodstream via the mononuclear phagocyte system (MPS). One of the most promising methods used to overcome this limitation is the MPS-cytoblockade, which forces the MPS to intensify the clearance of erythrocytes by injecting allogeneic anti-erythrocyte antibodies and, thus, significantly prolongs the circulation of nanoagents in the blood. However, on the way to the clinical application of this approach, the question arises whether the induced suppression of macrophage phagocytosis via the MPS-cytoblockade could pose health risks. Here, we show that highly cytotoxic doxorubicin- or clodronate-loaded liposomes, which are widely used for cancer therapy and biomedical research, induce a similar increase in the nanoparticle blood circulation half-life in mice as the MPS-cytoblockade, which only gently and temporarily saturates the macrophages with the organism's own erythrocytes. This result suggests that from the point of view of in vivo macrophage suppression, the MPS-cytoblockade should be less detrimental than the liposomal anti-cancer drugs that are already approved for clinical application while allowing for the substantial improvement in the nanoagent effectiveness.

Sex and gender perspectives in colorectal cancer

Historically women were frequently excluded from clinical trials and drug usage to protect unborn babies from potential harm. As a consequence, the impact of sex and gender on both tumour biology and clinical outcomes has been largely underestimated. Although interrelated and often used interchangeably, sex and gender are not equivalent concepts. Sex is a biological attribute that defines species according to their chromosomal makeup and reproductive organ, while gender refers to a chosen sexual identity. Sex dimorphisms are rarely taken into account, in either preclinical or clinical research, with inadequate analysis of differences in outcomes according to sex or gender still widespread, reflecting a gap in our knowledge for a large proportion of the target population. Underestimation of sex-based differences in study design and analyses has invariably led to 'one-drug' treatment regimens for both males and females. For patients with colorectal cancer (CRC), sex also has an impact on the disease incidence, clinicopathological features, therapeutic outcomes, and tolerability to anticancer treatments. Although the global incidence of CRC is higher in male subjects, the proportion of patients presenting right-sided tumours and BRAF mutations is higher among females. Concerning sex-related differences in treatment efficacy and toxicity, drug dosage does not take into account sex-specific differences in pharmacokinetics. Toxicity associated with fluoropyrimidines, targeted therapies, and immunotherapies has been reported to be more extensive for females with CRC than for males, although evidence about differences in efficacy is more controversial. This article aims to provide an overview of the research achieved so far into sex and gender differences in cancer and summarize the growing body of literature illustrating the sex and gender perspective in CRC and their impact in relation to tumour biology and treatment efficacy and toxicity. We propose endorsing research on how biological sex and gender influence CRC as an added value for precision oncology.

Chalcones and Gastrointestinal Cancers: Experimental Evidence

Colorectal (CRC) and gastric cancers (GC) are the most common digestive tract cancers with a high incidence rate worldwide. The current treatment including surgery, chemotherapy or radiotherapy has several limitations such as drug toxicity, cancer recurrence or drug resistance and thus it is a great challenge to discover an effective and safe therapy for CRC and GC. In the last decade, numerous phytochemicals and their synthetic analogs have attracted attention due to their anticancer effect and low organ toxicity. Chalcones, plant-derived polyphenols, received marked attention due to their biological activities as well as for relatively easy structural manipulation and synthesis of new chalcone derivatives. In this study, we discuss the mechanisms by which chalcones in both in vitro and in vivo conditions suppress cancer cell proliferation or cancer formation.

Distinct Nausea Profiles Are Associated With Gastrointestinal Symptoms in Oncology Patients Receiving Chemotherapy

BACKGROUND

Unrelieved chemotherapy-induced nausea (CIN) occurs 48% of patients undergoing chemotherapy and is one of the most debilitating symptoms that patients report.

OBJECTIVE

The aims of this study were to identify subgroups of patients with distinct CIN profiles and determine how these subgroups differed on demographic and clinical characteristics; severity, frequency, and distress of CIN; and the co-occurrence of common gastrointestinal symptoms.

METHODS

Patients (n = 1343) completed demographic questionnaire and Memorial Symptom Assessment Scale 6 times over 2 cycles of chemotherapy. Latent class analysis was used to identify subgroups of patients with distinct CIN profiles. Differences among these subgroups were evaluated using parametric and nonparametric statistics.

RESULTS

Four distinct CIN profiles were identified: none (40.8%), increasing-decreasing (21.5%), decreasing (8.9%), and high (28.8%). Compared with the none class, patients in the high class were younger, had a lower annual household income, had child care responsibilities, had a lower Karnofsky Performance Status score and a higher Self-administered Comorbidity Questionnaire score, and were more likely to have received chemotherapy on a 14-day cycle and a highly emetogenic chemotherapy regimen. In addition, patients in the high class reported high occurrence rates for dry mouth, feeling bloated, diarrhea, lack of appetite, abdominal cramps, difficulty swallowing, mouth sores, weight loss, and change in the way food tastes.

CONCLUSIONS

That 60% of the patients reported moderate to high CIN occurrence rates confirms that this unrelieved symptom is a significant clinical problem.

IMPLICATIONS FOR PRACTICE

Nurses need to evaluate patients' level of adherence to their antiemetic regimen and make appropriate referrals for physical therapy, psychological services, and dietary counseling.

Relationships Between Colorectal Cancer Survivors' Positive Psychology, Symptoms, and Quality of Life

This cross-sectional study examined colorectal cancer (CRC) survivors' symptom and symptom cluster characteristics (occurrence, frequency, and severity), positive psychology (benefit-finding and post-traumatic growth), and quality of life (QoL), and determined whether positive psychology moderates symptoms and QoL relationship during acute cancer survivorship, time from diagnosis to treatment completion. A total of 117 CRC survivors completed demographics, symptoms, QoL, and positive psychology questionnaires. Descriptive statistics, multiple linear regression, and moderation analyses were performed. Participants reported high QoL (94%, M = 5.15) and moderate-high positive psychology (75%, M = 3.21). Nineteen symptoms and five symptom clusters were inversely related to QoL (p < .05). Positive psychology (M = ~≥3.24) moderated the relationship of QoL (p < .05) with symptoms occurrence (n = 10), symptom severity (n = 1), and with the generalized symptom cluster (weakness, fatigue, dizziness, drowsy, sleep disturbances, and pain). Positive psychology aids in symptom management and improves QoL. Nurses are poised to identify, prevent, promote, and advocate self-management skills to improve health-related outcomes.

Factors associated with a high level of unmet needs and their prevalence in the breast cancer survivors 1-5 years after post local treatment and (neo)adjuvant chemotherapy during the COVID-19: A cross-sectional study

Objective

To assess the prevalence of unmet needs in post-treatment breast cancer survivors and identify sociodemographic, clinical, and psychosocial variables associated with reported unmet needs during the COVID-19 pandemic.

Materials and methods

In this cross-sectional study, 430 post-treatment breast cancer survivors, ranging between 1 and 5 years after the procedure, completed the Cancer Survivors' Unmet Needs (CaSUN) questionnaire from September 2021 and January 2022. The multivariate logistic analysis identified factors associated with at least one reported unmet need in the total CaSUN scale and specific domains.

Results

A total of 67% of survivors reported at least one unmet need. The most frequently reported unmet needs were the lack of accessible hospital parking (43%) and recurrence concerns (39.5%). The majority of reported unmet needs relate to comprehensive care (44%), followed by the psychological and emotional support domain (35.3%). Younger age (OR = 0.95, 95% CI = 0.92-0.99; p < 0.001), three or more comorbidities (OR = 0.27, 95% CI = 0.11-0.71, p < 0.01), a lower quality of life (OR = 0.06, 95% CI = 0.01-0.47, p < 0.01) and low resilience (OR = 0.95, 95% CI = 0.93-0.99) were associated with a high level of unmet needs in the multivariate regression model. Results are presented for factors associated with a high level of unmet needs for comprehensive cancer care and psychological and emotional support domain.

Conclusion

A high prevalence found in our study could be attributed to the COVID-19 pandemic, where patients may have missed adequate follow-up care, although comparing to studies done in non-pandemic time is difficult. Family physicians should be more attentive toward younger cancer survivors and those with more comorbidities as both characteristics can be easily recognized in the family practice.

Systematic self-reporting of patients’ symptoms: improving oncologic care and patients’ satisfaction

Background:

In recent years, there has been a growing interest to enhance patients’ symptom management during routine cancer care using patient-reported outcome measures. The goal of this study is to analyse patients’ responses to the Edmonton Symptom Assessment System (ESAS) to determine whether patient-reported outcomes could help characterise those patients with the highest supportive care needs and symptom burden in order to help provide targeted support for patients.

Methods:

In this study, we analysed ESAS questionnaire responses completed by patients as part of their routine care and considered part of patients’ standard of care. Statistical analyses were performed using the IBM SPSS Statistics version 26.0. Descriptive statistics are used to summarise patient demographics, disease characteristics and patient-reported symptom severity and prevalence.

Results:

The overall mean age is 65.2 ± 12.8 years comprising 43.8% male and 56.2% female patients. The five common primary disease sites are breast (26.2%), haematology (21.1%), gastrointestinal (15.3%), genitourinary (12.7%) and lung (12.0%) cancers. The mean severity for each symptom is all mild (score: 1–3). The three most common reported symptoms causing distress are tiredness, poor overall wellbeing and anxiety, and the least reported symptom is nausea.

Conclusions:

Systematic self-reporting of patients’ symptoms is important to improve symptom management, timely facilitation of appropriate intervention, patient experience, and patient and family satisfaction. The awareness of disease site, gender and age-related symptom variations should help in the design and provision of appropriate symptom-directed, tumour-specific and patient-focused interventions to meet patients’ immediate needs.

Symptom clusters and their predictors in patients with lung cancer and treated with programmed cell death protein 1 immunotherapy

Objective

The aims of this study were to examine the symptom severity and interference among patients with lung cancer treated with PD-1 immunotherapy, explore whether those symptoms were clustered together, and identify factors associated with symptom clusters.

Methods

A cross-sectional study was conducted. Data were collected by demographic and clinical characteristic questionnaires and the M.D. Anderson Symptom Inventory Lung Cancer Module. Symptom clusters were identified using exploratory factor analysis, and stepwise linear regression was applied to analyze the factors affecting the symptom clusters.

Results

A total of 148 patients with lung cancer treated with PD-1 immunotherapy participated in this study. The overall symptom burdens of these patients were mainly at a mild level. The patient symptom clusters identified in this study were a general cluster, a treatment-related cluster, a pulmonary cluster, a gastrointestinal cluster, and a neural cluster. The patients’ Karnofsky performance status (KPS) score (β ​= ​−2.758, P ​< ​0.001) and having a history of chemotherapy (β ​= ​4.384, P ​= ​0.001) were significant predictors of the general cluster. Their KPS scores (β ​= ​−1.202, P ​< ​0.001) and having a history of chemotherapy (β ​= ​−1.957, P ​= ​0.001) were significant predictors of the pulmonary cluster. Their monthly income (β ​= ​−0.316, P ​= ​0.030) and KPS scores (β ​= ​−0.357, P ​= ​0.045) were significant predictors of the gastrointestinal cluster. Having a history of chemotherapy (β ​= ​1.868, P ​< ​0.001) was the predictor of the neural cluster.

Conclusions

The symptom burdens of patients with lung cancer and treated with PD-1 immunotherapy were at a mild level and appeared to be clustered. In addition, because the symptoms that comprise a cluster are interrelated, the diagnosis and management of each symptom in a cluster should not be performed in isolation, and each symptom in a cluster should be treated either simultaneously or in an orderly manner.

Diet-microbiome interactions in cancer treatment: Opportunities and challenges for precision nutrition in cancer

Dietary patterns contribute to cancer risk. Separately, microbial factors influence the development of several cancers. However, the interaction of diet and the microbiome and their joint contribution to cancer treatment response needs more research. The microbiome significantly impacts drug metabolism, immune activation, and response to immunotherapy. One of the critical factors affecting the microbiome structure and function is diet. Data demonstrate that the diet and microbiome composition affects the immune response. Moreover, malnutrition is a significant confounder to cancer therapy response. There is little understanding of the interaction of malnutrition with the microbiome in the context of cancer. This review aims to address the current knowledge of dietary intake patterns and malnutrition among cancer patients and the impact on treatment outcomes. Second, this review will provide evidence linking the microbiome to cancer treatment response and provide evidence of the potentially strong effect that diet could have on this interaction. This review will formulate critical questions that will need further research to understand the diet-microbiome relationship in cancer treatment response and directions for future research to guide us to precision nutrition therapy to improve cancer outcomes.

Symptom experience of older oncology patients with low versus high levels of multimorbidity prior to chemotherapy

PURPOSE

Evaluate for differences in demographic and clinical characteristics between older oncology patients with low multimorbidity (<2 multimorbidities) and high multimorbidity (≥2 multimorbidities) and evaluate for differences in symptom occurrence, severity, and distress ratings between the two groups.

METHODS

Symptoms of older oncology patients (n = 125) were assessed using the Memorial Symptom Assessment Scale prior to chemotherapy administration. Data were analyzed using t-tests for continuous variables and Chi-square or Fisher's exact tests for categorical variables.

RESULTS

For the total sample, lack of energy and pain were the two most common symptoms. Compared to the low multimorbidity group, the high multimorbidity group had a higher number of symptoms and significantly higher occurrence rates for feeling nervous, difficulty sleeping, dry mouth, and pain. Compared to the low multimorbidity group, the high multimorbidity group had significantly higher severity ratings for pain, feeling sad, lack of energy, feeling drowsy, and worrying. For distress, the high multimorbidity group reported significantly higher ratings for pain, worrying, feeling sad, feeling nervous, and "I don't look like myself". No differences were found in any demographic or clinical characteristics between the two multimorbidity groups.

CONCLUSIONS

Multimorbidity is associated with higher symptom occurrence, severity, and distress in older oncology patients. Our findings suggest that the symptoms with the highest severity ratings were not the most distressing. Clinicians should identify multimorbidities and assess symptoms prior to chemotherapy to identify patients at increased risk and initiate referrals for interventions.

Nanocarriers as a Tool for the Treatment of Colorectal Cancer

Nanotechnology is a promising tool for the treatment of cancer. In the past decades, major steps have been made to bring nanotechnology into the clinic in the form of nanoparticle-based drug delivery systems. The great hope of drug delivery systems is to reduce the side effects of chemotherapeutics while simultaneously increasing the efficiency of the therapy. An increased treatment efficiency would greatly benefit the quality of life as well as the life expectancy of cancer patients. However, besides its many advantages, nanomedicines have to face several challenges and hurdles before they can be used for the effective treatment of tumors. Here, we give an overview of the hallmarks of cancer, especially colorectal cancer, and discuss biological barriers as well as how drug delivery systems can be utilized for the effective treatment of tumors and metastases.

Distinct profiles of multiple co-occurring symptoms in patients with gastrointestinal cancers receiving chemotherapy

PURPOSE

Identify subgroups of gastrointestinal (GI) cancer patients with distinct multiple co-occurring symptom profiles and evaluate for differences among these subgroups in demographic and clinical characteristics and quality of life (QOL) outcomes.

METHODS

Patients with GI cancers (n = 399) completed the Memorial Symptom Assessment Scale (MSAS) that was used to assess for multiple co-occurring symptoms. Latent class analysis (LCA) was used to identify subgroups of patients with distinct symptom profiles using symptom occurrence ratings. Differences in demographic and clinical characteristics and QOL outcomes among the subgroups were evaluated using parametric and nonparametric tests.

RESULTS

All Low (36.6%), Moderate (49.4%), and All High (14.0%) classes were identified. Compared to the All Low class, patients in the other two classes were significantly younger and were more likely to report depression and back pain. Compared to the other two classes, patients in the All High class had fewer years of education and a higher number of comorbidities. Significant differences were found among the three classes for comorbidity burden and total number of MSAS symptoms (i.e., All Low < Moderate < All High), as well as for performance status (i.e., All Low > Moderate > All High). A higher symptom burden was associated with poorer QOL outcomes.

CONCLUSIONS

The first study to identify subgroups of patients with GI cancers based on distinct symptom profiles. LCA allowed for the identification of risk factors associated with a higher symptom burden. Clinicians can use this information to identify high-risk patients and develop personalized symptom management interventions.

Coptidis Rhizoma Extract Reverses 5-Fluorouracil Resistance in HCT116 Human Colorectal Cancer Cells via Modulation of Thymidylate Synthase

Colorectal cancer (CRC) is a malignancy of the colon or rectum. It is ranked as the third most common cancer in both men and women worldwide. Early resection permitted by early detection is the best treatment, and chemotherapy is another main treatment, particularly for patients with advanced CRC. A well-known thymidylate synthase (TS) inhibitor, 5-fluorouracil (5-FU), is frequently prescribed to CRC patients; however, drug resistance is a critical limitation of its clinical application. Based on the hypothesis that Coptidis Rhizoma extract (CRE) can abolish this 5-FU resistance, we explored the efficacy and underlying mechanisms of CRE in 5-FU-resistant (HCT116/R) and parental HCT116 (HCT116/WT) cells. Compared to treatment with 5-FU alone, combination treatment with CRE and 5-FU drastically reduced the viability of HCT116/R cells. The cell cycle distribution assay showed significant induction of the G0/G1 phase arrest by co-treatment with CRE and 5-FU. In addition, the combination of CRE and 5-FU notably suppressed the activity of TS, which was overexpressed in HCT116/R cells, as compared to HCT116/WT cells. Our findings support the potential of CRE as an adjuvant agent against 5-FU-resistant colorectal cancers and indicate that the underlying mechanisms might involve inhibition of TS expression.

Recent investigations into synthesis and pharmacological activities of phenoxy acetamide and its derivatives (chalcone, indole and quinoline) as possible therapeutic candidates

Medicinal chemistry can rightfully be regarded as a cornerstone in the public health of our modern society that combines chemistry and pharmacology with the aim of designing and developing new pharmaceutical compounds. For this purpose, many chemical techniques as well as new computational chemistry applications are used to study the utilization of drugs and their biological effects. In the biological interface, medicinal chemistry constitutes a group of interdisciplinary sciences, as well as controlling its organic, physical and computational pillars. Therefore, medicinal chemists working to design an integrated and developing system that portends an era of novel and safe tailored drugs either by synthesizing new pharmaceuticals or to improving the processes by which existing pharmaceuticals are made. It includes researching the effects of synthetic, semi-synthetic and natural biologically active substances based on molecular interactions in terms of molecular structure with triggered functional groups or the specific physicochemical properties. The present work focuses on the literature survey of chemical diversity of phenoxy acetamide and its derivatives (Chalcone, Indole and Quinoline) in the molecular framework in order to get complete information regarding pharmacologically interesting compounds of widely different composition. From a biological and industrial point of view, this literature review may provide an opportunity for the chemists to design new derivatives of phenoxy acetamide and its derivatives that proved to be the successful agent in view of safety and efficacy to enhance life quality.

Sex-specific and gender-specific aspects in patient-reported outcomes

Patient-reported outcomes (PROs) are important tools in patient-centred medicine and allow for individual assessment of symptom burden and aspects of patients’ quality of life. While sex and gender differences have emerged in preclinical and clinical medicine, these differences are not adequately represented in the development and use of patient-reported outcome measures. However, even in personalised approaches, undesirable biases may occur when samples are unbalanced for certain characteristics, such as sex or gender. This review summarises the current status of the literature and trends in PROs with a focus on sex and gender aspects.

Neuropsychological Symptoms and Intrusive Thoughts Are Associated With Worse Trajectories of Chemotherapy-Induced Nausea

CONTEXT

Although chemotherapy-induced vomiting is well controlled with evidence-based antiemetic regimens, chemotherapy-induced nausea (CIN) remains a significant clinical problem.

OBJECTIVES

Study purposes, in a sample of outpatients with breast, gastrointestinal, gynecological, or lung cancer who received two cycles of chemotherapy (CTX, n = 1251), were to evaluate for interindividual differences in the severity of CIN and to determine which demographic, clinical, symptom, and stress characteristics are associated with higher initial levels as well as with the trajectories of CIN.

METHODS

Patients were recruited during their first or second cycle of CTX. Patients completed self-report questionnaires a total of six times over two cycles of CTX. Hierarchical linear modeling was used to evaluate for interindividual differences in and characteristics associated with the severity of CIN.

RESULTS

Across the two cycles of CTX, higher levels of sleep disturbance, depression, and morning fatigue, as well as higher levels of intrusive thoughts, were associated with higher initial levels of CIN. In addition, lower functional status scores and shorter cycle lengths were associated with higher initial levels of CIN, and younger age and higher emetogenicity of the CTX regimen were associated with both higher initial levels as well as worse trajectories of CIN severity.

CONCLUSION

These findings suggest that common symptoms associated with cancer and its treatment are associated with increased severity of CIN. Targeted interventions for these symptoms may reduce the burden of unrelieved CIN.

High symptom burden is associated with impaired quality of life in colorectal cancer patients during chemotherapy:A prospective longitudinal study

PURPOSE

Multiple symptoms can have a negative impact on quality of life (QoL), but there is little information about the impact of multiple symptoms on QoL of patients with colorectal cancer (CRC) during outpatient chemotherapy. Therefore, the purpose was to assess the physical and mental QoL in CRC patients over six months of chemotherapy, to evaluate the association of QoL with the presence of multiple symptoms, and to determine which demographic and clinical characteristics are associated with physical and mental QoL scores.

METHODS

Outpatients with CRC (N = 120) completed the Medical Outcomes Study Short Form (SF-12) and Memorial Symptom Assessment Scale (MSAS) at eight time points during six months of chemotherapy. Linear mixed models for repeated measures were used to analyse QoL over time; and its association with demographic and clinical characteristics; and with the presence of multiple symptoms (e.g., 'numbness/tingling' and 'problems with sexual interest').

RESULTS

The CRC patients had worse physical and mental QoL scores than the general population at all time points. Impaired physical QoL was significantly associated with psychological symptom burden (p < 0.001) and numbness/tingling (p < 0.027). Impaired mental QoL was associated with physical symptom burden (p < 0.001), with being female (p < 0.009), younger age (p < 0.024), and having problems with sexual interest (p < 0.009).

CONCLUSIONS

Impaired QoL was associated with symptoms in CRC outpatients. This information about the symptoms and characteristics associated with worse QoL during chemotherapy may help clinicians identify and inform at-risk patients.

Gastrointestinal symptoms are associated with trajectories of chemotherapy-induced nausea

PURPOSE

Between 19 and 58% of oncology patients experience chemotherapy-induced nausea (CIN). In a sample of outpatients with breast, gastrointestinal (GI), gynecological, and lung cancer, the study purposes were to evaluate for inter-individual differences in the severity of CIN over two cycles of chemotherapy (CTX) and to determine which demographic and clinical characteristics and GI symptoms were associated with higher initial levels as well as with the trajectories of CIN severity.

METHODS

Patients completed study questionnaires at six time points over two cycles of CTX. These questionnaires provided information on demographic and clinical characteristics, as well as the occurrence of twelve GI symptoms. Hierarchical linear modeling based on full maximum likelihood estimation was performed.

RESULTS

Of the 1251 patients, 47.2% reported CIN. Across two cycles of CTX, lower functional status scores and higher levels of comorbidity were associated with higher initial levels of CIN. Younger age and emetogenicity of the CTX regimen were associated with higher initial levels as well as worse trajectories of CIN. The occurrence of five GI symptoms (i.e., vomiting, lack of appetite, constipation, feeling bloated, and difficulty swallowing) was associated with higher initial levels of CIN. The occurrence of mouth sores was associated with higher initial levels as well as with worst trajectories of CIN.

CONCLUSIONS

This study is the first to identify distinct demographic, clinical, and GI symptom characteristics associated with CIN severity. These findings suggest that the etiology of CIN is complex and may warrant interventions beyond standard antiemetics.
