The assessment and management of chemotherapy-related toxicities in patients with breast cancer, colorectal cancer, and Hodgkin's and non-Hodgkin's lymphomas: A scoping review

Synergistic effects of abietic acid combined with doxorubicin on apoptosis induction in a human colorectal cancer cell line

Cancer is a significant global disease with high mortality and limited therapeutic options. Chemotherapy is a cancer treatment option; however, there are still issues, including severe side effects, inadequate response, and drug resistance. Abietic acid is a natural diterpene with diverse pharmacological properties and can be used for cancer treatment. Therefore, this study aimed to assess the anticancer efficacy of abietic acid in combination with doxorubicin, a highly clinically used chemotherapeutic agent. Biochemical investigations include initial viability assays, combination therapy using isobologram analysis, apoptosis and cell cycle assays, gene expression assay, ELISA analysis of protein expression, DNA fragmentation, and wound healing assays. The data showed that doxorubicin-abietic acid (DOX-AB) is an effective and safe anticancer combination for Caco-2 cells. DOX-AB had a high safety index with minimal cytotoxicity at the combination dose on normal WI-38 fibroblasts cells. DOX-AB significantly decreased the proliferation and viability of Caco-2 cells, with an increase in the apoptosis rate in the late stage and necrosis with cell cycle arrest at the G2/M phase. Significant changes in the expression of modulators related to apoptosis, inflammation, and epigenetics were observed in gene and protein levels. DOX-AB combination had more efficient anticancer activity than doxorubicin alone. This study suggested that the use of abietic acid in combination with doxorubicin is a promising treatment for colorectal cancer because it enhances doxorubicin activity at relatively low doses with minimal cytotoxicity and overcomes multidrug resistance in tumors; these findings merit further investigation.

The dynamic effects of nutritional status on chemotherapy-related toxicity in patients with non-Hodgkin's lymphoma

BACKGROUND/OBJECTIVES

Understanding the dynamic changes in nutritional status of patients with non-Hodgkin's lymphoma (NHL) during chemotherapy is crucial, as it significantly impacts chemotherapy-related toxicity and survival outcomes.

SUBJECTS/METHODS

This multi-center study included newly diagnosed NHL patients. Nutritional status and chemotherapy-related toxic effects were assessed over the first five chemotherapy sessions, with follow-ups conducted every 3 months. Patients were categorized into three groups based on pre-chemotherapy Patient-Generated Subjective Global Assessment (PG-SGA) scores: Group A (0-1), Group B (2-8), and Group C (>9). Repeated-measures ANOVA and Generalized Estimating Equations (GEE) models were used for analysis, with survival outcomes evaluated via Kaplan-Meier and Cox regression.

RESULTS

A total of 143 patients (mean age 50.26 ± 15.02 years) completed the study, over a median follow-up of 18.8 months. PG-SGA scores were highest in Group C during chemotherapy (P < 0.001), with significant time-group interaction effects (P < 0.001). Liver and kidney impairments worsened across all groups (P < 0.05), while gastrointestinal toxicity and bone marrow suppression initially decreased before increasing. GEE analysis showed that nutritional status positively influenced gastrointestinal toxicity (β = 0.05, P = 0.001) and bone marrow suppression (β = 0.04, P = 0.014). Malnourished patients exhibited worse pulmonary infection-free survival and overall survival (P < 0.05).

CONCLUSIONS

NHL patients are highly susceptible to malnutrition during chemotherapy, which exacerbates chemotherapy-related toxicities, particularly gastrointestinal effects and myelosuppression. Maintaining good initial nutrition is vital for reducing toxicities and improving survival outcomes.

Patients' and Clinicians' Perceptions of the Clinical Utility of Predictive Risk Models for Chemotherapy-Related Symptom Management: Qualitative Exploration Using Focus Groups and Interviews

BACKGROUND

Interest in the application of predictive risk models (PRMs) in health care to identify people most likely to experience disease and treatment-related complications is increasing. In cancer care, these techniques are focused primarily on the prediction of survival or life-threatening toxicities (eg, febrile neutropenia). Fewer studies focus on the use of PRMs for symptoms or supportive care needs. The application of PRMs to chemotherapy-related symptoms (CRS) would enable earlier identification and initiation of prompt, personalized, and tailored interventions. While some PRMs exist for CRS, few were translated into clinical practice, and human factors associated with their use were not reported.

OBJECTIVE

We aim to explore patients' and clinicians' perspectives of the utility and real-world application of PRMs to improve the management of CRS.

METHODS

Focus groups (N=10) and interviews (N=5) were conducted with patients (N=28) and clinicians (N=26) across 5 European countries. Interactions were audio-recorded, transcribed verbatim, and analyzed thematically.

RESULTS

Both clinicians and patients recognized the value of having individualized risk predictions for CRS and appreciated how this type of information would facilitate the provision of tailored preventative treatments or supportive care interactions. However, cautious and skeptical attitudes toward the use of PRMs in clinical care were noted by both groups, particularly in relationship to the uncertainty regarding how the information would be generated. Visualization and presentation of PRM information in a usable and useful format for both patients and clinicians was identified as a challenge to their successful implementation in clinical care.

CONCLUSIONS

Findings from this study provide information on clinicians' and patients' perspectives on the clinical use of PRMs for the management of CRS. These international perspectives are important because they provide insight into the risks and benefits of using PRMs to evaluate CRS. In addition, they highlight the need to find ways to more effectively present and use this information in clinical practice. Further research that explores the best ways to incorporate this type of information while maintaining the human side of care is warranted.

Symptom experiences and influencing factors in patients undergoing chemotherapy for gastrointestinal cancers: a qualitative study

Objective

To explore the symptom experiences and influencing factors of gastrointestinal (GI) cancer patients on chemotherapy (CTX) in China.

Methods

Semi-structured interviews were conducted with 13 GI cancer patients undergoing CTX. Following the Colaizzi 7-step analysis method, the interview data were read carefully, meaningful statements related to the research questions were extracted, coded, collected, and described in detail, and the authenticity of the theme was verified.

Results

Nine themes were grouped into two main areas including the characteristics of symptom experiences and influences on symptom experiences.

Conclusion

The symptom experiences of patients undergoing CTX for GI cancer is poor and influenced by multiple factors. Nurses need to pay attention to the assessment and monitoring of CTX-related symptoms, improve symptom recognition, enhance doctor-patient communication and social support, explore intelligent management methods, and increase the efficiency of healthcare services to improve patients' symptom experience.

Feasibility of a mobile health app-based self-management program for Chinese patients with breast cancer receiving chemotherapy: A randomized controlled pilot study

Objective

There are currently an increasing number of mobile health (mHealth) programs offered to patients with breast cancer undergoing chemotherapy, but their rate of adherence to app usage has remained low. This study aimed to examine the feasibility of an mHealth app-based program such as the adherence rate of app usage and determine the preliminary effects on self-efficacy, quality of life, symptom burden and healthcare utilization in these patients.

Methods

We conducted a randomized controlled pilot trial. Ninety-six participants were randomly allocated into either an intervention group or a control group (routine care plus a placebo app). The intervention group engaged in a 6-week self-regulation activity and received nurse-led social support via the app. The intention-to-treat principle was adopted. The generalized estimating equation was utilized to analyze the between-group, within-group and interaction effectiveness of this program.

Results

Totally 96 participants were enrolled from 16 May to 23 August 2022. The average rate of adherence to app usage increased from 4.8% at week 3 to 51.2% at week 6. There was a statistically significant reduction in the physiological efficacy scores of the intervention (p < .001) and control groups (p < .001) at week 6, compared with the baseline. At week 6, the intervention group reported a significantly lower symptom burden (p = .042) and significantly better physical well-being than the control group (p = .024).

Conclusions

It is feasible to perform an mHealth app-based self-management program for patients with breast cancer receiving chemotherapy. Nurses can utilize this program to facilitate patient self-management of symptoms during chemotherapy.

Antitumoral Agent-Induced Constipation: A Systematic Review

BACKGROUND

Constipation is a common symptom in patients receiving antitumoral treatment. The mechanisms underlying antitumoral agent-induced constipation (ATAIC) are poorly defined. This systematic review aimed to analyze and synthesize the available information related to the prevalence, etiology, and treatment of ATAIC.

METHODS

A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines was conducted. The review included human studies written in English, French, or Spanish involving patients with cancer and containing information about the prevalence, etiology, and treatment of ATAIC.

RESULTS

A total of 73 articles were included. The reported prevalence ranged from 0.8% to 86.6%. Six studies reported an ATAIC prevalence of over 50%. The prevalence rates of constipation of grades 3 and 4 ranged between 0 and 11%. The importance of enteric neuronal integrity in gastrointestinal function was reported. The articles with the highest levels of evidence in relation to ATAIC treatment obtained in this systematic review studied treatments with acupuncture, sweet potato, osteopath, probiotics, and moxibustion.

CONCLUSIONS

The prevalence of constipation in patients undergoing antitumoral treatment is very diverse. Studies specifically designed to report the prevalence of antineoplastic treatment-induced constipation are needed. The importance of enteric neuronal integrity in gastrointestinal function was described. Thus, neuroprotection could be an area of research for the treatment of chemotherapy-induced gastrointestinal disorders.

The safety of combining immune checkpoint inhibitors and platinum-based chemotherapy for the treatment of solid tumors: A systematic review and network meta-analysis

Objective

Combination treatment regimens consisting of both immune checkpoint inhibitors (ICI) and chemotherapeutic agents have emerged as the standard of care for a range of cancers. This network meta-analysis (NMA) examined the toxicity profiles and safety rankings of these different ICI-based combination regimens.

Methods

The PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched for all randomized controlled trials (RCTs) published as of March 1, 2022 comparing two or more treatment regimens in which at least one arm was comprised of an ICI + platinum-based chemotherapeutic regimen. Treatment-related adverse events (AEs) of any grade and AEs of grade 3 or higher were the primary endpoints for this analysis, while specific AE types were secondary endpoints. This NMA combined both direct and indirect comparisons when analyzing odds ratios (ORs) and the surface under the cumulative ranking curve (SUCRA) for different ICI-based treatment regimens.

Results

In total, 33 RCTs enrolling 19,012 cancer patients were included in this NMA. Of the analyzed regimens, avelumab + chemotherapy and camrelizumab + chemotherapy were associated with a significantly greater risk of AEs of any grade relative to ipilimumab + chemotherapy, durvalumab + chemotherapy, or pembrolizumab + chemotherapy. No significant differences in the risk of AEs of grade 3 or higher were observed when comparing different ICI regimens. Hepatotoxicity and pyrexia were the most common AEs associated with atezolizumab + chemotherapy treatment. Ipilimumab + chemotherapy was associated with a relatively higher risk of gastrointestinal and skin toxicity. Skin toxicity and hypothyroidism were the major AEs associated with nivolumab + chemotherapy. Fatigue and pneumonia were the most common AEs respectively associated with sugemalimab + chemotherapy and pembrolizumab + chemotherapy regimens.

Conclusions

Of the evaluated regimens, camrelizumab + chemotherapy and avelumab + chemotherapy were associated with significantly higher rates of AEs of any grade, whereas durvalumab and sintilimab were relatively safe PD-L1 and PD-1 inhibitors, respectively, when administered in combination with platinum-based chemotherapy. However, none of the evaluated ICI + chemotherapy regimens exhibited any differences with respect to the incidence of grade 3 or higher AEs, offering guidance that may be of value in routine clinical practice.

Using video consultations for clinical assessment and decision of treatment readiness before chemotherapy: A mixed-methods study among patients with gastrointestinal cancer and oncology nurses

Objective

To investigate the feasibility of clinical assessment and decision of treatment readiness before chemotherapy using video consultations, as perceived by gastrointestinal cancer patients and oncology nurses. In addition, to estimate reductions in travel time for patients and environmental carbon dioxide (CO2) emissions.

Methods

In a mixed-method study, patients with gastrointestinal cancer who participated in at least one video consultation during April-October 2019 completed a questionnaire on socioeconomic status, time and kilometers saved on travel. Kilometers saved were converted into reduced CO2 emissions. Descriptive statistics were used for analysis. Patients (n = 15) participated in semi-structured individual interviews, and five oncology nurses participated in a focus group interview.

Results

A total of 84/119 patients (71%) consented to video consultation and responded to the questionnaire. 69% were male, with a mean age of 66 years. For 46% of patients, a video consultation saved more than an hour of travel time. Avoiding a median travel distance of 120 km per patient (range, 2-450 km) reduced CO2 emissions by 7018 lb. Video consultations had other positive effects on patients, including avoiding waiting rooms, having more energy, and experiencing more focused interactions with nurses. Technical issues occurred rarely. Nurses found technical issues more troublesome, sometimes precluding complete assessments. They reported a need to rethink nursing practice to effectively provide care during video consultations.

Conclusions

Video consultations reduced CO2 emissions. In addition, they were beneficial for patients with gastrointestinal cancer. However, providing an optimal clinical assessment and decision of treatment readiness before chemotherapy requires testing patient equipment, technical skills and new oncology nursing competencies.

Effectiveness of a phone-based nurse monitoring assessment and intervention for chemotherapy-related toxicity: A randomized multicenter trial

Purpose

Anticancer treatment-related toxicities can impact morbidity and mortality, hamper the administration of treatment, worsen the quality of life and increase the burden on the healthcare system. Therefore, their prompt identification is crucial. NICSO (Italian Network for Supportive Care in Cancer) conducted a nationwide randomized trial to evaluate the role of a planned, weekly phone-based nurse monitoring intervention to prevent and treat chemotherapy, targeted therapy- and immunotherapy-related toxicities. Here, we report the results from the chemotherapy arm.

Methods

This was a nationwide, randomized, open-label trial conducted among 29 Italian centers (NCT04726020) involving adult patients with breast, colon, or lung cancer and a life expectancy ≥6 months receiving adjuvant chemotherapy. Patients received either a weekly nurse monitoring phone call and an educational leaflet reporting practical advice about prevention and treatment of toxicities (experimental group) or the educational leaflet only (control group).

Results

The addition of a nurse monitoring intervention may help reduce time spent with severe toxicities (grade ≥3), particularly those less frequently reported in clinical practice, such as fatigue. When considering grade 1–2 AEs, times with mild/moderate diarrhea, mucositis, fatigue and pain were shorter in the experimental arm. Time spent without AEs was significantly longer in the experimental arms for all the toxicities. The requirement for special medical attention was comparable between groups.

Conclusion

This study suggests the need for implementing a better system of toxicity assessment and management for patients treated with adjuvant chemotherapy to promote effective preventive and/or therapeutic intervention against these events.

Synthesis of dihydrofuran-3-one and 9,10-phenanthrenequinone hybrid molecules and biological evaluation against colon cancer cells as selective Akt kinase inhibitors

A series of dihydrofuran-3-one and 9,10-phenanthrenequinone hybrid compounds were synthetized through a one-pot gold-catalyzed oxidative cyclization and Aldol-type addition cascade reaction of homopropargylic alcohols with 9,10-phenanthrenequinone. The cytotoxicity of newly synthesized compounds was evaluated in CCK8 assay against different human cancer cells, showing significantly antiproliferative activity against tested tumor cell lines with a lowest IC₅₀ value of 0.92 μM over HCT-116. Further investigation revealed that the treatment of HCT-116 cell line with the promising compound 4c induced cell death as a selective Akt inhibitor. In addition, controlled experiments and molecular docking study suggested that the significant antitumor activity might be attributed to the unique hybrid structure, which implied the promising potential of this dual heterocycle hybrid method in the discovery of novel bioactive molecules with structural diversity.

Management of Treatment-Related Infectious Complications in High-Risk Hemato-Oncological Patients via Telemedicine

Background

Infectious complications, especially febrile neutropenia, in hemato-oncological patients are associated with considerable morbidity, mortality and expenses. Remote monitoring of physiological functions and thus early detection of adverse events via telemedicine could improve the safety of these high-risk patients and save financial resources by shortening the time-to-antibiotics.

Methods

Patients undergoing active cancer treatment in high risk of acquiring severe infection are selected and enrolled in this project. Each patient receives a digital blood pressure monitor, an infrared thermometer and a mobile hub (cell phone). In the comfort of their homes, patients measure their blood pressure/pulse and body temperature regularly or whenever they feel unwell. The obtained data are encrypted and forwarded via the mobile hub to the password-protected portal. The values registered outside the set-up range trigger the alarms, which are immediately sent to the designated physician who can check the portal in real-time from any device with an Internet connection, contact the patient, if need be, and initiate the anti-infective therapy almost instantly after the first symptoms occur.

Results

Fifty hemato-oncological patients were recruited between March 1, 2018 and August 1, 2020. Two hundred ninety-seven alarms of body temperature were registered and checked by the physician and patients were contacted in 18.5% of the cases (55/297). Among these 55 events, 13 required medical assistance, which makes it approximately one-quarter of all conducted telephone interventions (23.4%) and neither septic shock nor death due to treatment-related toxicity occurred.

Conclusion

Telemedicine seems like a useful tool to improve the safety of high risk hemato-oncological patients when treatment-related infectious complications are concerned.

The effect of web-based intervention programs on self-management and symptom management in patients with lymphoma: A systematic review of randomized controlled trials

AIM

This systematic review aimed to systematically summarize studies obtained through a database search and examine the effect of web-based intervention programs on self-management and symptom management in patients with lymphoma.

METHODS

A systematic review of randomized controlled trials was carried out. Cochrane Central Register of Controlled Trials, Web of Science, PubMed, CINAHL, Scopus, ProQuest, Science Direct, and Ovid databases were reviewed until January 2021. The flow chart of the Preferred Reporting Items for Systematic Review and Meta-Analysis checklist was used in the search procedure without setting a year limit. Population, Intervention, Comparison, Outcomes and Study criteria were determined by two independent investigators and published randomized controlled studies in English with lymphoma diagnosis and web-based intervention programs for self-management and symptom management were included in the systematic review. The included studies were examined for their risk of bias with the help of the Cochrane Collaboration tool. A narrative synthesis of study findings was performed.

RESULTS

Six randomized controlled trials with 2382 participants were included in the systematic review. Web-based intervention programs in patients diagnosed with lymphoma were found to be generally implemented for determining the levels of self-management and symptom management. In all of the studies reviewed, it was found that the interventions had treatment outcomes. The risk of Bias 2 was evaluated as high risk in two studies that did not meet the criteria for blinding outcome evaluations. The included studies, while evaluating the effects of web-based intervention programs on patient outcomes, could not provide information about the underlying mechanisms by which these effects occur and how they occur.

CONCLUSIONS

All of the studies included were found to apply a technology designed to improve outcomes in patients with lymphoma. It is recommended that web-based intervention programs be individualized by adapting them to lymphoma types and stages, and serve as a guide for effective symptom management.

Phase I Dose-Escalation Trial of an Innovative Chemotherapy Regimen Combining a Fractionated Dose of Irinotecan Plus Bevacizumab, Oxaliplatin, 5-Fluorouracil, and Folinic Acid (bFOLFIRINOX-3) in Chemorefractory Metastatic Colorectal Cancer

Simple Summary

Treatment of non-resectable metastatic colorectal cancer (mCRC) involves chemotherapy based on 5-fluorouracil, oxaliplatin and irinotecan and monoclonal antibodies targeting VEGF or EGFR. After an initial progression, it is usual to change the chemotherapy regimen and targeted therapy, with rather moderate results. Several studies have focused on the interest of using again already used molecules and rechallenge with oxaliplatin and irinotecan bi fractionation (FOLFIRI3) have previously shown efficacy in chemorefractory patients, but desynchronized triplet chemotherapy was never tested. The aim of this study was to evaluate the safety and efficacy of a new regimen so-called: FOLFIRINOX-3 bevacizumab in chemorefractory metastatic colorectal cancer.

Abstract

The care of metastatic colorectal cancers is based on combination chemotherapies including 5-fluorouracil, oxaliplatin, irinotecan, and monoclonal antibodies targeting the epidermal growth factor receptor or vascular endothelial growth factor. The regimen is determined based on the patient’s molecular biology and general condition. Irinotecan bifractionation showed efficacy in chemorefractory patients in a previous study, FOLFIRI-3, but a desynchronized triplet has never been tested. The aim of bFOLFIRINOX-3 is to determine the safety, tolerance, and efficacy of a new regimen (FOLFIRINOX-3 bevacizumab) in chemorefractory patients. The aim of this study was to evaluate the safety and efficacy of FOLFIRINOX-3 bevacizumab in chemorefractory metastatic colorectal cancer (mCRC). A standard phase I, “3 + 3” design study was performed. The standard protocol comprised simplified FOLFOX 4 (folinic acid 400 mg/m²), 5-fluorouracil (a 400 mg/m² bolus followed by 2400 mg/m² for 46 h), oxaliplatin (85 mg/m²) and irinotecan (administered before and after 5-fluorouracil infusion), plus bevacizumab (5 mg/kg). In a “3 + 3” design, three different doses of irinotecan were tested: 60, 70 and 90 mg/m². The primary endpoint was the maximum tolerable dose (MTD) of irinotecan. The secondary endpoints included the objective response (at 8 and 16 weeks) according to the RECIST 1.1 criteria and progression free survival. Thirteen patients were enrolled, and twelve patients were finally evaluated for dose-limiting toxicity (DLT). The dose level defined was 70 mg/m² irinotecan. A total of three DLTs were observed (grade 3 diarrhea): two DLTs at the 90 mg/m² dose level and one at the 70 mg/m² dose level. The most frequently described adverse events were asthenia (93%), diarrhea (77%), nausea (62%) and peripheral sensory neuropathy (46%). The most frequent biological event was thrombopenia (54%). Regarding efficacy, among the 11 evaluable patients, no progression was observed at 8 weeks, and the partial response rate was 18.2%. At 16 weeks, a partial response rate of 27.3% was observed, and five patients had a stable disease. The new regimen of bFOLFIRINOX-3 with irinotecan at 70 mg/m² was well tolerated. In chemorefractory patients, this protocol shows a high response rate.

5-Oxo-hexahydroquinoline and 5-oxo-tetrahydrocyclopentapyridine derivatives as promising antiproliferative agents with potential apoptosis-inducing capacity

Discovery of novel anticancer agents is of crucial importance to expand the therapeutic options for cancer patients. In this study, a series of 49 5-oxo-hexahydroquinoline and 5-oxo-tetrahydrocyclopentapyridine analogs, containing different pyridine alkyl carboxylates at C₃ and various aliphatic, aromatic, and heteroaromatic substitutions at the C₄ position of the central core, were synthesized. The target compounds were tested for antiproliferative effect against three human cancer cell lines including MOLT-4 (acute lymphoblastic leukemia), K562 (chronic myelogenous leukemia), and MCF-7 (breast adenocarcinoma) by MTT assay, and the effect of the most potent derivatives on cell cycle was evaluated by RNase/propidium iodide (PI) flow cytometric assay. Generally, 5-oxo-hexahydroquinoline derivatives (E series) possessed superior antiproliferative activities compared to their 5-oxo-tetrahydrocyclopentapyridine counterparts (F series). 5-Oxo-hexahydroquinoline compounds bearing 2-pyridyl propyl carboxylate (group D) and 3-pyridyl propyl carboxylate (group E) were better antiproliferative agents than those bearing other pyridyl alkyl carboxylates. Five best compounds with IC₅₀ values in the range of 9.5-22.9 µM against MOLT-4 cells were selected for cell-cycle analysis, which revealed that derivatives D5, E3, and E5 with 2,3-dichlorophenyl, 3-nitrophenyl, and 2-nitrophenyl substitutions at C₄ position, respectively, may induce apoptosis in MOLT-4 cells. Molecular docking analysis, which was employed to make some predictions on the interaction of the most active derivatives with the binding site of Bcl-2 and Bcl-xL proteins, suggested that the compounds may be well accommodated within the binding sites of these anti-apoptotic proteins via hydrogen-bonding and hydrophobic interactions. The findings of this study present 5-oxo-hexahydroquinoline derivatives as antiproliferative agents with potential apoptosis-inducing ability in cancer cells.

Real time remote symptom monitoring during chemotherapy for cancer: European multicentre randomised controlled trial (eSMART)

OBJECTIVE

To evaluate effects of remote monitoring of adjuvant chemotherapy related side effects via the Advanced Symptom Management System (ASyMS) on symptom burden, quality of life, supportive care needs, anxiety, self-efficacy, and work limitations.

DESIGN

Multicentre, repeated measures, parallel group, evaluator masked, stratified randomised controlled trial.

SETTING

Twelve cancer centres in Austria, Greece, Norway, Republic of Ireland, and UK.

PARTICIPANTS

829 patients with non-metastatic breast cancer, colorectal cancer, Hodgkin's disease, or non-Hodgkin's lymphoma receiving first line adjuvant chemotherapy or chemotherapy for the first time in five years.

INTERVENTION

Patients were randomised to ASyMS (intervention; n=415) or standard care (control; n=414) over six cycles of chemotherapy.

MAIN OUTCOME MEASURES

The primary outcome was symptom burden (Memorial Symptom Assessment Scale; MSAS). Secondary outcomes were health related quality of life (Functional Assessment of Cancer Therapy-General; FACT-G), Supportive Care Needs Survey Short-Form (SCNS-SF34), State-Trait Anxiety Inventory-Revised (STAI-R), Communication and Attitudinal Self-Efficacy scale for cancer (CASE-Cancer), and work limitations questionnaire (WLQ).

RESULTS

For the intervention group, symptom burden remained at pre-chemotherapy treatment levels, whereas controls reported an increase from cycle 1 onwards (least squares absolute mean difference -0.15, 95% confidence interval -0.19 to -0.12; P<0.001; Cohen's D effect size=0.5). Analysis of MSAS sub-domains indicated significant reductions in favour of ASyMS for global distress index (-0.21, -0.27 to -0.16; P<0.001), psychological symptoms (-0.16, -0.23 to -0.10; P<0.001), and physical symptoms (-0.21, -0.26 to -0.17; P<0.001). FACT-G scores were higher in the intervention group across all cycles (mean difference 4.06, 95% confidence interval 2.65 to 5.46; P<0.001), whereas mean scores for STAI-R trait (-1.15, -1.90 to -0.41; P=0.003) and STAI-R state anxiety (-1.13, -2.06 to -0.20; P=0.02) were lower. CASE-Cancer scores were higher in the intervention group (mean difference 0.81, 0.19 to 1.43; P=0.01), and most SCNS-SF34 domains were lower, including sexuality needs (-1.56, -3.11 to -0.01; P<0.05), patient care and support needs (-1.74, -3.31 to -0.16; P=0.03), and physical and daily living needs (-2.8, -5.0 to -0.6; P=0.01). Other SCNS-SF34 domains and WLQ were not significantly different. Safety of ASyMS was satisfactory. Neutropenic events were higher in the intervention group.

CONCLUSIONS

Significant reduction in symptom burden supports the use of ASyMS for remote symptom monitoring in cancer care. A "medium" Cohen's effect size of 0.5 showed a sizable, positive clinical effect of ASyMS on patients' symptom experiences. Remote monitoring systems will be vital for future services, particularly with blended models of care delivery arising from the covid-19 pandemic.

Telemedicine in Malignant and Nonmalignant Hematology: Systematic Review of Pediatric and Adult Studies

BACKGROUND

Telemedicine, including video-, web-, and telephone-based interventions, is used in adult and pediatric populations to deliver health care and communicate with patients. In the realm of hematology, telemedicine has recently been used to safely and efficiently monitor treatment side-effects, perform consultations, and broaden the reach of subspecialty care.

OBJECTIVE

We aimed to synthesize and analyze information regarding the feasibility, acceptability, and potential benefits of telemedicine interventions in malignant and nonmalignant hematology, as well as assess the recognized limitations of these interventions.

METHODS

Studies were identified through a comprehensive Medical Subject Headings (MeSH) search on the PubMed MEDLINE, Controlled Register of Clinical Trials (Cochrane CENTRAL from Wiley), Embase, and CINAHL (EBSCO) databases on February 7, 2018. A second search, utilizing the same search strategy, was performed on October 1, 2020. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in the reporting of included evidence. Included studies were original articles researching the feasibility, acceptability, and clinical outcomes of telemedicine or telehealth interventions in pediatric or adult populations with malignant or nonmalignant hematological conditions. Data items in the extraction form included first author name, publication year, country, malignant or nonmalignant hematological condition or disease focus of the study, participant age, participant age subgroup (pediatric or adult), study design and setting, telemedicine intervention type and description, study purpose, and main study outcomes.

RESULTS

A total of 32 articles met the preset criteria and were included in this study. Most (25/32) studies were conducted in adults, and the remaining (7/32) were conducted in the pediatric population. Of the 32 studies, 12 studied malignant hematological conditions, 18 studied nonmalignant conditions, and two studied both malignant and nonmalignant conditions. Study types included pilot study (11/32), retrospective study (9/32), randomized controlled trial (6/32), cross-sectional study (2/32), case study (1/32), pre-post study (1/32), noncomparative prospective study (1/32), and prospective cohort study (1/32). The three main types of telemedicine interventions utilized across all studies were video-based (9/32), telephone-based (9/32), and web-based interventions (14/32). Study results showed comparable outcomes between telemedicine and traditional patient encounter groups across both pediatric and adult populations for malignant and nonmalignant hematological conditions.

CONCLUSIONS

Evidence from this review suggests that telemedicine use in nonmalignant and malignant hematology provides similar or improved health care compared to face-to-face encounters in both pediatric and adult populations. Telemedicine interventions utilized in the included studies were well received in both pediatric and adult settings. However, more research is needed to determine the efficacy of implementing more widespread use of telemedicine for hematological conditions.

Low-dose CDK4/6 inhibitors induce presentation of pathway specific MHC ligands as potential targets for cancer immunotherapy

Cyclin dependent kinase 4/6 inhibitors (CDK4/6i) lead to cell-cycle arrest but also trigger T cell-mediated immunity, which might be mediated by changes in human leukocyte antigen (HLA) ligands. We investigated the effects of CDK4/6i, abemaciclib and palbociclib, on the immunopeptidome at nontoxic levels in breast cancer cell lines by biochemical identification of HLA ligands followed by network analyses. This treatment led to upregulation of HLA and revealed hundreds of induced HLA ligands in breast cancer cell lines. These new ligands were significantly enriched for peptides derived from proteins involved in the “G1/S phase transition of cell cycle” including HLA ligands from CDK4/6, Cyclin D1 and the 26S regulatory proteasomal subunit 4 (PSMC1). Interestingly, peptides from proteins targeted by abemaciclib and palbociclib, were predicted to be the most likely to induce a T cell response. In strong contrast, peptides induced by solely one of the drugs had a lower T cell recognition score compared to the DMSO control suggesting that the observed effect is class dependent. This general hypothesis was exemplified by a peptide from PSMC1 which was among the HLA ligands with highest prediction scores and which elicited a T cell response in healthy donors. Overall, these data demonstrate that CDK4/6i treatment gives rise to drug-induced HLA ligands from G1/S phase transition, that have the highest chance for being recognized by T cells, thus providing evidence that inhibition of a distinct cellular process leads to increased presentation of the involved proteins that may be targeted by immunotherapeutic agents.

Prevalence of Fatigue in Patients With Cancer: A Systematic Review and Meta-Analysis

CONTEXT

Fatigue is a particularly common and troubling symptom that has a negative impact on quality of life throughout all phases of treatment and stages of the illness among patients with cancer.

OBJECTIVES

The objective of this meta-analysis is to examine the present status of fatigue prevalence in patients with cancer.

METHODS

The following databases were searched: PubMed, MEDLINE, EMBASE, PsycINFO, Cochrane Library, from inception up to February 2020. Prevalence rates were pooled with meta-analysis using a random-effects model. Heterogeneity was tested using I-squared (I2) statistics.

RESULTS

A total of 129 studies (N = 71,568) published between 1993 and 2020 met the inclusion criteria. The overall prevalence of fatigue was 49% (34,947 of 71,656 participants, 95% CI = 45-53) with significant heterogeneity between studies (P < 0.000; τ2 = 0.0000; I2 = 98.88%). Subgroup analyses show that the prevalence of fatigue related to type of cancer ranged from 26.2% in patients with gynecological cancer to 56.3% in studies that included mixed types of cancer. In advanced cancer stage patients, the highest prevalence of fatigue (60.6%) was reported. Fatigue prevalence rates were 62% during treatment and 51% during mixed treatment status. The prevalence of fatigue decreased from 64% in studies published from 1996 to 2000 to 43% in studies published from 2016 to 2020. Metaregression identified female gender as a significant moderator for higher prevalence of fatigue, whereas mean age is not associated with fatigue.

CONCLUSION

This meta-analysis highlights the importance of developing optimal monitoring strategies to reduce fatigue and improve the quality of life of patients with cancer.

The development and initial evaluation of the Diarrhoea Management Diary (DMD) in patients with metastatic breast cancer

PURPOSE

Chemotherapy-induced diarrhoea (CID) is a common, but often underreported problem in patients with breast cancer that has a profound effect on quality of life. It is best measured from a patient's perspective, but tools are limited. The aim of this study was to develop and evaluate the Diarrhoea Management Diary (DMD), a self-report measure to assess CID, use of self-management strategies and treatment adherence.

METHODS

The DMD was constructed using an iterative process of instrument development: concept elicitation (literature review), item generation and reduction (cognitive debriefing), and pilot testing in the target population. After translation into eight languages, the DMD was used in an international randomised trial for women receiving lapatinib and capecitabine for metastatic breast cancer with or without prophylactic octreotide. Patterns of missing data and sensitivity to change were examined.

RESULTS

The understandability and completeness of the 8-item DMD was confirmed in cognitive interviews and pilot testing. Practicability of the DMD was evaluated in 62 women with metastatic breast cancer (median age 57). Up to 68% reported CID at any given time-point, and 19% had diarrhoea at each time-point. Patients also described efficacy of different strategies for diarrhoea management. Missing data were associated with study discontinuation. DMD missing item response was 0.9%. Sensitivity to change was good at most assessment points.

CONCLUSIONS

Although further psychometric testing is recommended, initial evaluation of the DMD showed good content validity and practicability in international research with cancer patients.

Towards early monitoring of chemotherapy-induced drug resistance based on single cell metabolomics: Combining single-probe mass spectrometry with machine learning

Despite the presence of methods evaluating drug resistance during chemotherapies, techniques, which allow for monitoring the degree of drug resistance in early chemotherapeutic stage from single cells in their native microenvironment, are still absent. Herein, we report an analytical approach that combines single cell mass spectrometry (SCMS) based metabolomics with machine learning (ML) models to address the existing challenges. Metabolomic profiles of live cancer cells (HCT-116) with different levels (i.e., no, low, and high) of chemotherapy-induced drug resistance were measured using the Single-probe SCMS technique. A series of ML models, including random forest (RF), artificial neural network (ANN), and penalized logistic regression (LR), were constructed to predict the degrees of drug resistance of individual cells. A systematic comparison of performance was conducted among multiple models, and the method validation was carried out experimentally. Our results indicate that these ML models, especially the RF model constructed on the obtained SCMS datasets, can rapidly and accurately predict different degrees of drug resistance of live single cells. With such rapid and reliable assessment of drug resistance demonstrated at the single cell level, our method can be potentially employed to evaluate chemotherapeutic efficacy in the clinic.

Oxaliplatin-Induced Neurotoxic Side Effects and Their Impact on Daily Activities: A Longitudinal Study Among Patients With Colorectal Cancer

BACKGROUND

Oxaliplatin (OXA) is frequently used in the treatment of patients with colorectal cancer, and OXA-induced neurotoxic side effects are common. Reports on real-time patient-reported neurotoxic side effects and impact on the patient's daily activities are sparse in existing studies.

OBJECTIVE

The aim of this study was to identify and assess patient-reported OXA-induced neurotoxic side effects and their impact on the patient's daily activities, during and after chemotherapy.

METHODS

In a multicenter prospective longitudinal study, 46 chemo-naïve patients with colorectal cancer treated with postoperative adjuvant OXA-based chemotherapy were monitored during treatment and at 3-, 6-, 9-, and 12-month follow-ups. Patients were recruited from September 2013 to June 2016. In total, 370 Oxaliplatin-Associated Neurotoxicity Questionnaire responses were available for analysis. A mobile phone-based system was used to receive real-time assessments.

RESULTS

All patients reported neurotoxic side effects and impact on daily activities during treatment. The side effects changed in character and body location over time and had an impact on the daily activities.

CONCLUSIONS

The high prevalence of OXA-induced neurotoxic side effects significantly interfered with the patients' daily activities. We found significant differences between baseline data and follow-up time points for neurotoxicity, and the patients had not returned to baseline after 1 year.

IMPLICATIONS FOR PRACTICE

The real-time assessment using mobile phone technology seems to be a valuable tool for monitoring patient-reported neurotoxicity and interventions for tailored care. Effectively identifying neurotoxicity and its impact on the patient's daily activities is important in supportive cancer care.

Implementation of the Symptom Navi © Programme for cancer patients in the Swiss outpatient setting: a study protocol for a cluster randomised pilot study (Symptom Navi© Pilot Study)

INTRODUCTION

Self-management interventions show promising results on symptom outcomes and self-management behaviours. The Symptom Navi© Programme (SN©P) is a nurse-led intervention supporting patients' symptom self-management during anticancer treatment. It consists of written patient information (Symptom Navi© Flyers (SN©Flyers)), semistructured consultations and a training manual for nurses.

METHODS AND ANALYSIS

This pilot study will evaluate the implementation of the SN©P based on the Reach Effectiveness-Adoption Implementation Maintenance framework at Swiss outpatient cancer centres. We will use a cluster-randomised design and randomise the nine participating centres to the intervention or usual care group. We expect to include 140 adult cancer patients receiving first-line systemic anticancer treatment. Trained nurses at the intervention clusters will provide at least two semistructured consultations with the involvement of SN©Flyers. Outcomes include patients' accrual and retention rates, patient-reported interference of symptoms with daily functions, symptom burden, perceived self-efficacy, quality of nursing care, nurse-reported facilitators and barriers of adopting the programme, nurses' fidelity of providing the intervention as intended, and patients' safety (patients timely reporting of severe symptoms). We will use validated questionnaires for patient-reported outcomes, focus group interviews with nurses and individual interviews with oncologists. Linear mixed models will be used to analyse patient-reported outcomes. Focus group and individual interviews will be analysed by thematic analysis.

ETHICS AND DISSEMINATION

The Symptom Navi© Pilot Study has been reviewed and approved by Swiss Ethic Committee Bern (KEK-BE: 2017-00020). Results of the study will be disseminated in peer-reviewed journal and at scientific conferences.

TRIAL REGISTRATION NUMBER

NCT03649984; Pre-results.

Adaptation and Implementation of a Mobile Phone-Based Remote Symptom Monitoring System for People With Cancer in Europe

BACKGROUND

There has been an international shift in health care, which has seen an increasing focus and development of technological and personalized at-home interventions that aim to improve health outcomes and patient-clinician communication. However, there is a notable lack of empirical evidence describing the preparatory steps of adapting and implementing technology of this kind across multiple countries and clinical settings.

OBJECTIVE

This study aimed to describe the steps undertaken in the preparation of a multinational, multicenter randomized controlled trial (RCT) to test a mobile phone-based remote symptom monitoring system, that is, Advanced Symptom Management System (ASyMS), designed to enhance management of chemotherapy toxicities among people with cancer receiving adjuvant chemotherapy versus standard cancer center care.

METHODS

There were 13 cancer centers across 5 European countries (Austria, Greece, Ireland, Norway, and the United Kingdom). Multiple steps were undertaken, including a scoping review of empirical literature and clinical guidelines, translation and linguistic validation of study materials, development of standardized international care procedures, and the integration and evaluation of the technology within each cancer center.

RESULTS

The ASyMS was successfully implemented and deployed in clinical practices across 5 European countries. The rigorous and simultaneous steps undertaken by the research team highlighted the strengths of the system in clinical practice, as well as the clinical and technical changes required to meet the diverse needs of its intended users within each country, before the commencement of the RCT.

CONCLUSIONS

Adapting and implementing this multinational, multicenter system required close attention to diverse considerations and unique challenges primarily related to communication and clinical and technical issues. Success was dependent on collaborative and transparent communication among academics, the technology industry, translation partners, patients, and clinicians as well as a simultaneous and rigorous methodological approach within the 5 relevant countries.

Aconselhamento telefônico: identificação de sintomas em pacientes com linfoma em quimioterapia antineoplásica

Resumo Objetivo Identificar os sinais e sintomas apresentados por pacientes com Linfoma de Hodgkin submetidos ao protocolo quimioterápico composto por Doxorrubicina, Bleomicina, Vimblastina e Dacarbazina (ABVD) por meio de aconselhamento telefônico e comparar os escores de gradação dos sinais e sintomas apresentados nos ciclos do protocolo. Métodos Descritivo, prospectivo, quantitativo. Sete pacientes receberam aconselhamento telefônico, em 24 tempos de chamadas programadas e não programadas, correspondentes a 6 ciclos de quimioterapia com protocolo ABVD. Utilizou-se o Inventário de Sintomas do M.D Anderson e o Critério Comum de Terminologia para Eventos Adversos, para a gradação dos sintomas e um protocolo de condutas. Realizou-se análise descritiva e analítica. Resultados Duzentas e oitenta e seis chamadas telefônicas geraram1.870 queixas sintomáticas. Nas chamadas programadas, as queixas com maior prevalência foram fadiga, preocupações, falta de apetite, vômitos e náuseas. Quanto a interferência nas atividades de vida diária, os itens relacionados a atividades em geral, no trabalho e dificuldade para caminhar, além de alterações no humor foram relatados em maior frequência. Nas chamadas não programadas, a falta de apetite e desregulação menstrual foram as queixas mais recorrentes. Na análise da progressão dos sintomas, observou-se aumento de náuseas e vômitos (p=0,02), diminuição da fadiga e falta de ar (p≤0,03), melhora do sono (p=0,02) e diminuição do estresse (p=0,02). Conclusão A fadiga, náusea, vômito e alteração nas atividades de trabalho foram relatados frequentemente. Houve progressão de náuseas e vômitos, mas regressão da fadiga e do estresse. O aconselhamento telefônico permitiu a comunicação e o manejo rápido de um número expressivo de sintomas.

A scoping review of trials of interventions led or delivered by cancer nurses

BACKGROUND

Advances in research and technology coupled with an increased cancer incidence and prevalence have resulted in significant expansion of cancer nurse role, in order to meet the growing demands and expectations of people affected by cancer (PABC). Cancer nurses are also tasked with delivering an increasing number of complex interventions as a result of ongoing clinical trials in cancer research. However much of this innovation is undocumented, and we have little insight about the nature of novel interventions currently being designed or delivered by cancer nurses.

OBJECTIVES

To identify and synthesise the available evidence from clinical trials on interventions delivered or facilitated by cancer nurses.

DATA SOURCES AND REVIEW METHODS

A systematic review of randomised controlled trials (RCT), quasi-RCTs and controlled before and after studies (CBA) of cancer nursing interventions aimed at improving the experience and outcomes of PABC. Ten electronic databases (CENTRAL, MEDLINE, AMED, CINAHL, EMBASE, Epistemonikos, CDSR, DARE, HTA, WHO ICTRP) were searched between 01 January 2000 and 31 May 2016. No language restrictions were applied. Bibliographies of selected studies and relevant Cochrane reviews were also hand-searched. Interventions delivered by cancer nurses were classified according to the OMAHA System. Heat maps were used to highlight the volume of evidence available for different cancer groups, intervention types and stage of cancer care continuum.

RESULTS

The search identified 22,450 records; we screened 16,169 abstracts and considered 925 full papers, of which 214 studies (247,550 participants) were included in the evidence synthesis. The majority of studies were conducted in Europe (n = 79) and USA (n = 74). Interventions were delivered across the cancer continuum from prevention and risk reduction to survivorship, with the majority of interventions delivered during the treatment phase (n = 137). Most studies (131/214) had a teaching, guidance or counselling component. Cancer nurse interventions were targeted at primarily breast, prostate or multiple cancers. No studies were conducted in brain, sarcoma or other rare cancer types. The majority of the studies (n = 153) were nurse-led and delivered by specialist cancer nurses (n = 74) or advanced cancer nurses (n = 29), although the quality of reporting was poor.

CONCLUSIONS

To the best of our knowledge, this is the first review to synthesise evidence from intervention studies across the entire cancer spectrum. As such, this work provides new insights into the nature of the contribution that cancer nurses have made to evidence-based innovations, as well as highlighting areas in which cancer nursing trials can be developed in the future.
