Testing Symptom Severity Thresholds and Potential Alerts for Clinical Intervention in Patients With Cancer Undergoing Chemotherapy

Baduanjin Mind-Body Exercise for Cancer-Related Fatigue: Protocol for a Remotely Delivered Randomized Wait-List Controlled Feasibility Study

BACKGROUND

People living with a cancer diagnosis often experience cancer-related fatigue (CRF). Between 9% and 45% of people report CRF as moderate to severe, negatively impacting their quality-of-life (QOL). The evidence-base for managing CRF recommends exercise-related therapies over pharmaceutical interventions. One such exercise-like therapy is Baduanjin mind-body exercise (MBE), which has additional benefits. A remotely delivered program may further benefit people with CRF. The primary objective of this pilot will test study feasibility of a remotely delivered Baduanjin MBE exercise program for people living with CRF.

METHODS

This is a randomized wait-list controlled pilot study and will take place in Sydney, Australia. Subject to informed consent, 40 adults with moderate CRF levels and receiving or previously received adjuvant chemotherapy, will undertake a home-based 8-week Baduanjin MBE program supported by online resources and instructors. The primary feasibility outcomes are recruitment, enrollment, retention, and adherence rates; and safety as measured by tolerance and adverse-event frequency. Clinical outcomes (eg, changes in CRF, QOL, and participant perceptions) are assessed at pre-intervention, week 1, week 4, week 8, and post-intervention. Analyses follows the Intent-to-Treat (all participants as per randomization) and per-protocol (participants adhering to the protocol). Missing data will be imputed from previous data entries and regression models may be tested to predict missing outcomes.

DISCUSSION

To our knowledge, this is the first study evaluating the feasibility and effects of Baduanjin MBE on CRF using a remote delivery method. These feasibility data will inform a fully powered future trial investigating evidence of effect on CRF and QOL.Trial registration: Australian and New Zealand Clinical Trials Registry (ANZCTR 12623000177651).Ringgold ID: 651498 Chinese Medicine Centre.

Effects of a Geriatric Assessment Intervention on Patient-Reported Symptomatic Toxicity in Older Adults With Advanced Cancer

PURPOSE

Providing a geriatric assessment (GA) summary with management recommendations to oncologists reduces clinician-rated toxicity in older patients with advanced cancer receiving treatment. This secondary analysis of a national cluster randomized clinical trial (ClinicalTrials.gov identifier: NCT02054741) aims to assess the effects of a GA intervention on symptomatic toxicity measured by Patient-Reported Outcomes Common Terminology Criteria for Adverse Events (PRO-CTCAE).

METHODS

From 2014 to 2019, the study enrolled patients age ≥ 70 years, with advanced solid tumors or lymphoma and ≥ 1 GA domain impairment, who were initiating a regimen with high prevalence of toxicity. Patients completed PRO-CTCAEs, including the severity of 24 symptoms (11 classified as core symptoms) at enrollment, 4-6 weeks, 3 months, and 6 months. Symptoms were scored as grade ≥ 2 (at least moderate) and grade ≥ 3 (severe/very severe). Symptomatic toxicity was determined by an increase in severity during treatment. A generalized estimating equation model was used to assess the effects of the GA intervention on symptomatic toxicity.

RESULTS

Mean age was 77 years (range, 70-96 years), 43% were female, and 88% were White, 59% had GI or lung cancers, and 27% received prior chemotherapy. In 706 patients who provided PRO-CTCAEs at baseline, 86.1% reported at least one moderate symptom and 49.7% reported severe/very severe symptoms at regimen initiation. In 623 patients with follow-up PRO-CTCAE data, compared with usual care, fewer patients in the GA intervention arm reported grade ≥ 2 symptomatic toxicity (overall: 88.9% v 94.8%, P = .035; core symptoms: 83.4% v 91.7%, P = .001). The results for grade ≥ 3 toxicity were comparable but not significant (P > .05).

CONCLUSION

In the presence of a high baseline symptom burden, a GA intervention for older patients with advanced cancer reduces patient-reported symptomatic toxicity.

Shortness of Breath on Day 1 After Surgery Alerting the Presence of Early Respiratory Complications After Surgery in Lung Cancer Patients

PURPOSE

Patient-reported outcome (PRO)-based symptom assessment with a threshold can facilitate the early alert of adverse events. The purpose of this study was to determine whether shortness of breath (SOB) on postoperative day 1 (POD1) can inform postoperative pulmonary complications (PPCs) for patients after lung cancer (LC) surgery.

METHODS

Data were extracted from a prospective cohort study of patients with LC surgery. Symptoms were assessed by the MD Anderson Symptom Inventory-lung cancer module (MDASI-LC) before and daily after surgery. Types and grades of complications during hospitalization were recorded. SOB and other symptoms were tested for a possible association with PPCs by logistic regression models. Optimal cutpoints of SOB were derived, using the presence of PPCs as an anchor.

RESULTS

Among 401 patients with complete POD1 MDASI-LC and records on postoperative complications, 46 (11.5%) patients reported Clavien-Dindo grade II-IV PPCs. Logistic regression revealed that higher SOB score on POD1 (odds ratio [OR]=1.13, 95% CI=1.01-1.27), male (OR=2.86, 95% CI=1.32-6.23), open surgery (OR=3.03, 95% CI=1.49-6.14), and lower forced expiratory volume in one second (OR=1.78, 95% CI=1.66-2.96) were significantly associated with PPCs. The optimal cutpoint was 6 (on a 0-10 scale) for SOB. Patients reporting SOB < 6 on POD1 had shorter postoperative length of stay than those reporting 6 or greater SOB (median, 6 vs 7, P =0.007).

CONCLUSION

SOB on POD1 can inform the onset of PPCs in patients after lung cancer surgery. PRO-based symptom assessment with a clinically meaningful threshold could alert clinicians for the early management of PPCs.
