The COVID-19 pandemic: An opportunity to rethink and harmonise the frequency of follow-up visits for patients with early stage breast cancer

The COVID-19 pandemic and its effects on follow-up of patients with early breast cancer: A patient survey

PURPOSE

Despite limited evidence supporting its effectiveness, most guidelines recommend long-term, routinely scheduled in-person surveillance of patients with early breast cancer (EBC). The COVID-19 pandemic led to increased use of virtual care. This survey evaluated patient perspectives on follow-up care.

METHODS

Patients with EBC undergoing surveillance were surveyed about follow-up protocols, perceptions, and interest in clinical trials assessing different follow-up strategies.

RESULTS

Of 402 approached patients 270 completed the survey (response rate 67%). Median age 62.5 years (range 25-86) and median time since breast cancer diagnosis was 3.8 years (range < 1-33 years). Most (n = 148/244, 60%) were followed by more than one provider. Routine follow-ups with breast examination were mostly conducted by medical/radiation oncologists every 6 months (n = 110/236, 46%) or annually (n = 106/236, 44%). Participants felt routine follow-up was useful to monitor for recurrence, manage side effects of cancer treatment and to provide support/reassurance. Most participants felt regular follow-up care would detect recurrent cancer earlier (n = 214/255, 96%) and increase survival (n = 218/249, 88%). The COVID-19 pandemic reduced the number of in-person visits for 54% of patients (n = 63/117). Patients were concerned this reduction of in-person visits would lead to later detection of both local (n = 29/63, 46%) and distant recurrences (n = 25/63, 40%). While many felt their medical and radiation oncologists were the most suited to provide follow-up care, 55% felt comfortable having their primary care provider (PCP) conduct surveillance. When presented with a scenario where follow-up has no effect on earlier detection or survival, 70% of patients still wanted routine in-person follow-up for reassurance (63%) with the goal of earlier recurrence detection (56%).

CONCLUSIONS

Despite limited evidence of effectiveness of routine in-person assessment, patients continue to place importance on regularly scheduled in-person follow-up.

Telephone completion of patient self-reporting health history documents by registered nurses: a survey to evaluate its effectiveness and strategies for improvement

AIM

Prior to the COVID-19 pandemic, cancer patients would complete their self-reporting health history documentation at their initial consultation visit. With the increase in virtual care, a program was established; whereby, a registered nurse (RN) would complete the self-reporting history with the patient by telephone prior to the initial consultation. A survey of RNs and oncologists evaluating the effectiveness of this program is presented.

METHODS

Outpatient RNs and medical and radiation oncologists were surveyed at a single Canadian cancer center. The surveys collected demographic information and perceptions around the successes and challenges of this program.

RESULTS

Responses were received from 31/42 (74%) RNs and 29/48 (60%) oncologists. RNs reported calling an average of 4 patients/week, and the median time for each call was 20 min. For responding RNs, 21/31 (68%) felt patients were satisfied with the process, and 18/31 (58%) were satisfied with the quality and efficacy of care they were delivering. 25/31 (81%) RNs felt the telephone calls improved care when the patient came to the clinic. All (100%) oncologists were aware of the program, and 86% (25/29) felt it saved time at the consult visit. Areas for improvement included patients completing the forms themselves and including information on current symptoms and drug insurance status.

CONCLUSION

COVID-19 has resulted in many changes in oncology practice. Completion of patient self-reported health history documentation by an RN over the telephone prior to consultation visit received positive feedback from both RNs and oncologists. However, this process has considerable RN resource implications.

How Frequently Should Patients with Breast Cancer Have Routine Follow-Up Visits?

Prospective Data Regarding the Optimal Frequency and ModalityProspective data regarding the optimal frequency and modality of follow up after definitive therapy for localized breast cancer is lacking, especially as it relates to time to recurrence detection. This article reviews the evidence and proposes a randomized trial to evaluate on-demand versus guideline-based survivorship care.

Regularly scheduled physical examinations and the detection of breast cancer recurrences

PURPOSE

Follow-up care of early breast cancer (EBC) patients usually includes routinely scheduled physical examinations. While ASCO guidelines recommend a physical exam every three to six months for the first three years, little evidence supports this schedule. We evaluated recurrence detection of patients transferred into a single centre survivorship program that follows ASCO recommendations.

METHODS

Patients with EBC referred to the Wellness Beyond Cancer Program (WBCP) who had breast cancer recurrence between February 1, 2013, and January 1, 2019 were reviewed. Descriptive analyses were used to present patient and disease characteristics stratified by type of recurrence and mode of cancer detection.

RESULTS

Of 206 recurrences, 135 were distant recurrences (65.5%), 41 were ipsilateral breast recurrences (19.9%), and 30 were contralateral breast primaries (14.6%). Distant recurrences were primarily detected via patient-reported symptoms (125/135, 92.6%). 53.7% (22/41) of ipsilateral breast recurrences were detected by patients and 41.5% (17/41) by routine imaging. Contralateral breast primaries were primarily detected by imaging 83.3% (25/30) and patient-reported symptoms 16.7% (5/30). Only 2/206 (1.14%) recurrences/new primaries were detected by healthcare providers at routinely scheduled follow-up visits.

CONCLUSIONS

Despite following ASCO guidelines, healthcare providers rarely detect recurrences at routinely scheduled follow-up appointments. Our data suggests that approximately 35, 000 follow-up visits were required for healthcare providers to detect these 2 recurrences. While reduced in-person visits may affect other aspects of follow-up care (e.g. toxicity management), it appears unlikely, provided patients attend regular screening tests, that less frequent in-person follow-up is associated with worse breast cancer-related outcomes.

Integrating Systematic Reviews into Supportive Care Trial Design: The Rethinking Clinical Trials (REaCT) Program

PURPOSE

To review the successes and challenges of integrating systematic reviews (SRs) into the Rethinking Clinical Trials (REaCT) Program.

METHODS

All REaCT program SRs were evaluated and descriptive summaries presented.

RESULTS

Twenty-two SRs have been performed evaluating standard of care interventions for the management of: breast cancer (n = 15), all tumour sites (n = 4), breast and prostate cancers (n = 2), and prostate cancer (n = 1). The majority of SRs were related to supportive care (n = 14) and survivorship (n = 5) interventions and most (19/22, 86%) confirmed the existence of uncertainty relating to the clinical question addressed in the SR. Most SRs (15/22, 68%) provided specific recommendations for future studies and results were incorporated into peer-reviewed grant applications (n = 6) and clinical trial design (n = 12). In 12/22 of the SRs, the first author was a trainee. All SRs followed PRISMA guidelines.

CONCLUSION

SRs are important for identifying and confirming clinical equipoise and designing trials. SRs provide an excellent opportunity for trainees to participate in research.

A Randomized Trial Comparing 3- versus 4-Monthly Cardiac Monitoring in Patients Receiving Trastuzumab-Based Chemotherapy for Early Breast Cancer

PURPOSE

The optimal frequency for cardiac monitoring of left ventricular ejection fraction (LVEF) in patients receiving trastuzumab-based therapy for early breast cancer (EBC) is unknown. We conducted a randomized controlled trial comparing 3- versus 4-monthly cardiac monitoring.

PATIENTS AND METHOD

Patients scheduled to receive trastuzumab-containing cancer therapy for EBC with normal (>53%) baseline LVEF were randomized to undergo LVEF assessments every 3 or 4 months. The primary outcome was the change in LVEF from baseline. Secondary outcomes included the rate of cardiac dysfunction (defined as a decrease in the LVEF of ≥10 percentage points, to a value <53%), delays in or discontinuation of trastuzumab therapy, and cardiology referral.

RESULTS

Of the 200 eligible and enrolled patients, 100 (50%) were randomized to 3-monthly and 100 (50%) to 4-monthly cardiac monitoring. Of these patients, 98 and 97 respectively underwent at least one cardiac scan. The estimated mean difference in LVEF from baseline was -0.94% (one-sided 95% lower bound: -2.14), which exceeded the pre-defined non-inferiority margin of -4%. There were also no significant differences between the two study arms for any of the secondary endpoints. The rate of detection of cardiac dysfunction was 16.3% (16/98) and 12.4% (12/97) in the 3- and 4-monthly arms, respectively (95% CI: 4.0 [-5.9, 13.8]).

CONCLUSIONS

Cardiac monitoring every 4 months was deemed non-inferior to that every 3 months in patients with HER2-positive EBC being treated with trastuzumab-based therapy. Given its costs and inconvenience, cardiac monitoring every 4 months should be considered standard practice. Registration: NCT02696707, 18 February 2016.

The Rethinking Clinical Trials (REaCT) Program. A Canadian-Led Pragmatic Trials Program: Strategies for Integrating Knowledge Users into Trial Design

We reviewed patient and health care provider (HCP) surveys performed through the REaCT program. The REaCT team has performed 15 patient surveys (2298 respondents) and 13 HCP surveys (1033 respondents) that have addressed a broad range of topics in breast cancer management. Over time, the proportion of surveys distributed by paper/regular mail has fallen, with electronic distribution now the norm. For the patient surveys, the median duration of the surveys was 3 months (IQR 2.5-7 months) and the median response rate was 84% (IQR 80-91.7%). For the HCP surveys, the median survey duration was 3 months (IQR 1.75-4 months), and the median response rate, where available, was 28% (IQR 21.2-49%). The survey data have so far led to: 10 systematic reviews, 6 peer-reviewed grant applications and 19 clinical trials. Knowledge users should be an essential component of clinical research. The REaCT program has integrated surveys as a standard step of their trials process. The COVID-19 pandemic and reduced face-to-face interactions with patients in the clinic as well as the continued importance of social media highlight the need for alternative means of distributing and responding to surveys.
