    Abstract: Background: Pyrotinib (an irreversible tyrosine kinase inhibitor targeting EGFR, HER2, and HER4) plus capecitabine previously demonstrated a statistically significant improvement in progression-free survival (PFS) over placebo plus capecitabine for HER2-positive local relapsed or metastatic breast cancer after prior trastuzumab and taxanes in the interim analysis of the PHENIX trial (NCT02973737; Jiang Z et al. Oral presentation at ASCO 2019, Abstract 1001). It is shown that patients also benefit from subsequent pyrotinib monotherapy after progressed on capecitabine alone. Here we present an updated OS from a follow-up period with a median of 42.1 months. Methods: This PHENIX trial enrolled patients with HER2-positive local relapsed or metastatic breast cancer who had received prior trastuzumab and taxanes and up to two prior lines of chemotherapy for relapsed or metastatic disease. Eligible patients were randomized 2:1 to receive pyrotinib (400 mg orally once daily) in combination with capecitabine (1000 mg/m2 orally twice daily on days 1-14 for 21-day cycles; P+C group) or placebo plus capecitabine followed by pyrotinib monotherapy upon disease progression (C-P group). Randomization was stratified by the presence of visceral disease (yes vs. no) and the hormone receptor status (estrogen receptor [ER]- and/or progesterone receptor [PR] -positive vs. ER- and PR-negative). The primary endpoint was the independent review committee-assessed PFS. The data cutoff for the updated OS analysis was January 15, 2021. Results: A total of 279 eligible patients were randomized, with 185 to P+C group and 94 to C-P group. As of data cutoff, the median duration of follow-up was 41.7 months (95% CI 40.2-42.4) in P+C group and 43.1 months (95% CI 38.8-44.5) in C-P group. 71 out of 94 patients who progressed on placebo plus capecitabine received pyrotinib monotherapy as the first subsequent anti-cancer therapy according to protocol. Excluding the protocol prespecified pyrotinib monotherapy, 129 (69.7%) patients in the P+C group and 74 (78.7%) patients in the C-P group received anti-cancer therapy after discontinuing study treatment, and 107 (57.8%) patients and 61 (64.9%) patients received post-discontinuation anti-HER2 drugs, respectively. 98 (53.0%) of the 185 patients in P+C group and 59 (62.8%) of the 94 patients in C-P group died by the time of data cutoff. Kaplan-Meier estimated median OS was 34.9 months (95% CI 28.4-42.1) in P+C group and 23.6 months (95% CI 19.3-34.4) in C-P group (HR 0.74, 95% CI 0.54-1.02; p=0.068). The 2-year OS rate was 65.2% (95% CI 57.6%-71.8%) versus 48.9% (95% CI 38.1%-58.7%), respectively. Subgroup analyses of OS were generally consistent with the overall result (Table 1). Conclusion: The updated OS analysis highlighted the long-term efficacy of pyrotinib plus capecitabine in pretreated HER2-positive local relapsed or metastatic breast cancer. We did not observe a statistically significant difference in OS between pyrotinib plus capecitabine group and capecitabine group followed by subsequent pyrotinib monotherapy upon disease progression.

    Abstract: Background: In the international Phase III COmparisoN of Faslodex In Recurrent or Metastatic breast cancer (CONFIRM) study, fulvestrant 500 mg was associated with significantly longer progression-free survival (PFS) over the 250 mg dose (hazard ratio [HR] 0.80; 95% confidence interval [CI] 0.68, 0.94; p=0.006) in postmenopausal women with advanced breast cancer (ABC) following failure on prior endocrine therapy. There were no clinically meaningful differences between the treatment groups in terms of the incidence or severity of adverse events. The present study was designed to compare the efficacy and safety of fulvestrant 500 mg versus 250 mg in a Chinese population for registration purposes. Methods: This was a Phase III randomized, double-blind study in a Chinese population (ClinicalTrials.gov: NCT01300351). Postmenopausal women with estrogen receptor positive (ER+) ABC following failure on prior endocrine (antiestrogen [AO] or aromatase inhibitor [AI] ) therapy were randomized 1:1 to fulvestrant 500 mg or 250 mg. Patients (pts) were stratified by post-AO/post-AI status and enrollment of post-AI pts was capped at 45%. Primary study endpoint was PFS. Consistency with the global CONFIRM study was to be concluded if the HR for the treatment comparison of PFS was & lt;1 (full analysis set; stratified log-rank test); the study was not powered to detect significant differences between treatment groups. Secondary endpoints included pharmacokinetics, ORR, CBR, DoR, DoCB, safety and tolerability. Results: 221 pts were randomized to fulvestrant 500 mg (n=111) or fulvestrant 250 mg (n=110). 121 pts were in the post-AO subgroup and 100 pts were in the post-AI subgroup. Demographic and baseline characteristics were balanced between fulvestrant 500 mg and fulvestrant 250 mg and comparable with those in the global CONFIRM study. 98% (119/121) in the post-AO subgroup and 92% (92/100) in the post-AI subgroup had adjuvant endocrine therapy, while only 12% (14/121) in the post-AO subgroup and 51% (51/100) in the post-AI subgroup used salvage endocrine therapy. At the time of the primary analysis, 152 progression events (69%) had occurred (post-AO 59% [71/121]; post-AI 81% [81/100] ). Median PFS was 8.0 months (m) in the fulvestrant 500 mg group vs 4.0 m in the 250 mg group (HR 0.75; 95% CI 0.54, 1.03; p=0.078); the predefined criterion for consistency with the global CONFIRM study was met. In a predefined subgroup analysis of PFS, the HR for fulvestrant 500 mg vs 250 mg was & lt;1 in both post-AO (median PFS 8.1 m vs 5.6 m; HR 0.86; 95% CI 0.54, 1.37) and post-AI (median PFS 5.8 m vs 2.9 m; HR 0.65; 95% CI 0.42, 1.03) subgroups. Secondary endpoints favored fulvestrant 500 mg over 250 mg, with the exception of median DoR. Safety and tolerability profiles were consistent with the known safety profile of fulvestrant. Conclusions: Data from the present study support the superior clinical benefit of fulvestrant 500 mg vs 250 mg demonstrated in the global CONFIRM study, in postmenopausal Chinese women with ER+ ABC. Hazard ratios favoring fulvestrant 500 mg were observed in both the post-AO and post-AI settings.

    Abstract: Background: There is still no standard chemotherapy for patients with metastatic triple-negative breast cancer (mTNBC). Our previous phase II pilot trial with first-line gemcitabine and cisplatin combination (GP) in patients with mTNBC (clinicaltrials.gov Identifier: NCT00601159) showed a median progression-free survival (PFS) of 6.2 months. In this Chinese Breast Cancer Study Group (CBCSG) 006 trial (clinicaltrials.gov Identifier: NCT01287624) we explored in a randomized trial the role of the less costly GP regimen versus the standard GT [Gemcitibine + paclitaxel] chemotherapy for the metastatic breast cancer as a first line treatment for mTNBC. Trial objectives: progression free survival [PFS]; overall survival [OS] ; and toxicity. Methods: In the trial with a hybrid trial design incorporating a formal test of superiority as well as noninferiority, mTNBC patients with no previous chemotherapy for metastatic disease were randomly assigned to receive either GP regimen (G/P: 1250 mg/m2 d1,8/ 75 mg/m2 d1) or the GT regimen (same G; T: 175 mg/m2 d1). Results: Between Jan. 2011 and Nov., 2013, 236 patients were randomized [118 patients / arm], and all received at least one dose of assigned chemotherapy. As of Mar. 20, 2014, the intent-to-treat analysis showed 201 recurrences and 97 deaths. Objective response rates of GP vs GT were 67.9% vs. 50.4% (P= 0.008), with median PFS of 232 vs. 194 days (HR=0.692, 95% CI 0.523-0.915; P= 0.009). Overall survival of patients from the GP vs. the GT arms was median 672 vs. 556 days (HR=0.902, 95% CI 0.605-1.344; P= 0.611). Significant differences in grade 3/4 adverse events were seen for nausea, vomiting, anemia and thrombocytopenia [GP vs. GT, 6.8 vs. 0.8%; 11.0 vs. 0.8%; 33.1 vs. 51.0%; and 32.2 vs. 2.5%, respectively]. In addition, assessment of adverse events of any grade showed the GP regimen had more anorexia, constipation, hypomagnesemia and hypokalemia, while GT regimen had significantly more alopecia and peripheral neuropathy. The delivered relative dose intensity was & gt; 90% for all three drugs, with the total number of delivered cycles of chemotherapy in GP and GT arms being 654 and 648 [average 5.54 and 5.49 /patient], respectively. Conclusions: 1.The Gemcitabine + Platinum is superior to Gemcitabine + Paclitaxel in terms of objective response rates and duration of PFS. 2.While grade 3 / 4 nausea & vomiting, and anemia, were heavier for the GP combination, the delivery of chemotherapy and average number of cycles delivered were comparable between the two arms. 3.Overall survival data will be updated on the conference to indicate the long-term effect of the somehow more toxic GP regimen, which shows nevertheless superiority of response rates and of the PFS over the more costly GT regimen.

    Abstract: Background: Circulating tumor cell (CTC) and serum HER2 ECD can all reflect an aggressive tumor behavior. We performed this prospective, monocenter, double-blinded study to investigate the potential clinical significance of combined detection of CTC and serum HER2 ECD for advanced breast cancer patients with histological HER2-positivity. Methods: A total of 88 eligible patients were enrolled in the present study from April 2012 to October 2013. We used Cell search system and ADVIA Centaur System to detect CTC and serum HER2 ECD respectively. Patients received systemic treatment according to national and international guidelines. Results: Twenty nine (33%) patients had ≥5 CTC, seventy three (83%) patients had serum HER2 ECD values of at least 15ng/ml, twenty seven (30.7%) patients had both elevated CTC and ECD values and fourteen (15.9%) patients had both normal CTC and ECD values. Patients with both normal CTC and serum HER2 ECD values exhibited a significantly longer median PFS than patients with both elevated values (9.0 months versus 2.8 months, p=0.023) and exhibited a trend toward longer PFS compared with patients with elevated CTC or ECD values (9.0 months versus 4.2 months, p=0.065), patients with both or one elevated values showed similar median PFS (2.8 months versus 4.2 months, p=0.211) (Figure1). Conclusions: The combined detection of CTC and serum HER2 ECD showed prognostic significance for HER-2 positive advanced breast cancer patients, patients with both normal values exhibited longer median PFS than others.

    Abstract: Background: A combination of a taxane, trastuzumab, and pertuzumab (THP) is the standard-of-care (SOC) 1L treatment for patients (pts) with HER2+ mBC; THP demonstrated median progression-free survival (mPFS) of 18.7 mo and overall survival (OS) of 56.5 mo (Swain et al. N Engl J Med. 2015;372:724-734). However, pts eventually develop resistance to treatment. Novel treatment options are necessary in order to delay the emergence of resistance and provide better clinical outcomes, improve quality of life (QOL), and prolong survival in the 1L setting. T-DXd has demonstrated efficacy in pts with heavily pretreated HER2+ mBC, with an objective response rate (ORR) of 61.4%, duration of response (DOR) of 20.8 mo, and mPFS of 19.4 mo (Modi et al. Cancer Res. 2021. Abstract PD3-06). Data from DESTINY-Breast01 supported global approvals of T-DXd in HER2+ mBC. Here we describe a phase 3 trial evaluating the efficacy and safety of T-DXd ± pertuzumab compared with THP in the 1L treatment of HER2+ mBC. Trial design: DESTINY-Breast09 (NCT04784715) is a global, multicenter, randomized, phase 3 trial assessing the efficacy and safety of T-DXd with or without pertuzumab compared with SOC THP as 1L treatment in pts with HER2+ (IHC 3+ or ISH+ assessed locally per ASCO-CAP guidelines and centrally confirmed) advanced or mBC. This study consists of 3 treatment arms: arm A (T-DXd + placebo), arm B (T-DXd + pertuzumab), and arm C (THP). Randomization is 1:1:1 and pts will be stratified by prior treatment status (de novo vs recurrent), hormone receptor status (positive vs negative), and PIK3CA mutation status (detected vs not detected). Pts (N≈1134) must have had no prior chemotherapy or HER2-targeted therapy for advanced or mBC (1 prior line of endocrine therapy is allowed for mBC). The primary endpoint is PFS by blinded independent central review. Secondary endpoints include PFS by investigator assessment, OS, ORR, DOR, PFS2, health-related quality of life (QOL), pharmacokinetics, immunogenicity, and safety.

    Abstract: Background: A dose relationship may exist for both antitumor activity and toxicity of docetaxel in breast cancer (BC) patients, while 86% grade 4 neutropenia and 12% febrile neutropenia (FN) were reported when pretreated advanced breast cancer (ABC) patients received 100 mg/m2 docetaxel monotherapy without hematopoietic support. PHEDRA was a randomized, double-blind, multicenter, phase 3 study comparing the efficacy and safety of adding pyrotinib to trastuzumab and docetaxel as neoadjuvant treatment in women with HER2+ early or locally ABC (ClinicalTrials.gov: NCT03588091). We conducted this exploratory analysis to evaluate the effectiveness of mecapegfilgrastim, a long-acting recombinant human granulocyte colony-stimulating factor (rhG-CSF), as primary prophylaxis for neoadjuvant chemotherapy-induced neutropenia in BC patients. Methods: Patients with HER2-positive early or locally ABC were randomly assigned (1:1) to pyrotinib arm receiving 4 neoadjuvant cycles of docetaxel (100 mg/m2 iv d1 q3w), trastuzumab (8 mg/kg iv, cycle 1 d1, then 6 mg/kg d1 q3w), and pyrotinib (400 mg po qd, d1-21, q3w) or placebo arm with placebo, trastuzumab and docetaxel. Per protocol, patients were required to receive a single, 6-mg fixed dose of mecapegfilgrastim on Day 2 of each cycle. Other G-CSF was permitted if mecapegfilgrastim was unavailable at the local center or patients occurred mecapegfilgrastim intolerance. The incidence of neutropenia, FN, time to first neutropenia onset, duration per neutropenia event and cumulative neutropenia duration during neoadjuvant treatment period; and the incidences of grade 3/4 neutropenia, FN and decreased WBC count in Cycle 1 to 4 (C1-4) were presented. The data cutoff date was April 30, 2021. Results: Between July 23, 2018 and January 8, 2021, 355 patients were randomized (pyrotinib arm, n=178; placebo arm, n=177). Among them, 291 (82.0%) patients received a single, 6-mg fixed dose of mecapegfilgrastim in Cycle 1 and 270 (76.1%) patients received mecapegfilgrastim in each of the 4 cycles. Grade 3/4 neutropenia was reported in 33 (18.5%) patients in the pyrotinib arm and 36 (20.3%) patients in the placebo arm. Five (2.8%) patients in the pyrotinib arm and 2 (1.1%) patients in the placebo arm developed FN (5 FN occurred in C1; 2 FN occurred in C2). Median duration of grade 3/4 neutropenia was 3 days in the pyrotinib group and 3 days in the placebo group. Median cumulative duration of grade 3/4 neutropenia was 4 days and 3 days in the pyrotinib group and the placebo group, respectively. Grade 3/4 neutropenia mainly occurred during the first cycle of treatment for both pyrotinib (13.5%) and placebo arm (15.8%), reduced in the second cycle (5.9% vs 4.0%) and thereafter (C3: 1.8% vs 3.4%; C4: 2.4% vs 1.7%). Similar trends were observed for grade 3/4 WBC count decreased in Cycle 1 to 4. No grade 4 infection occurred. Overview of neutropenia, FN and WBC count decreased was summarized in Table 1. Consistent findings were observed in 291 mecapegfilgrastim treated patients. Conclusion: The exploratory analysis demonstrated 6-mg fixed dose of mecapegfilgrastim was effective when administrated as primary prophylaxis for neoadjuvant chemotherapy-induced neutropenia, which could be considered as a new treatment option for its advantage of once-per-cycle dosing and convenient dose management.

    Abstract: Objective To discuss the optimizing selection of maintenance treatment after xeloda-contained chemotherapy regimen being applicated in HER-2 negative, HR positive relapsing metastatic breast cancer(MBC) patients, and contrast the curative effect of maintenance treatment with xeloda or endocrine. Methods 119 patients with HER-2 negative, HR positive were enrolled during 2009-2013.All patients taking the xeloda contained chemotherapy regimens to obtain CR,PR or SD were randomly divided into group A(65 cases, maintenance capecitabine therapy 800-1000mg/ m2 bid, orally, Days 1 ∼ 14, q3w)and group B(54 cases, a switch to maintenance endocrine therapy). Endpoints include overall survival (OS) and progression-free survival (PFS). Results The ages, menopausal status, number of metastases and treatment line numbers had no statistical differences between two groups, and the p value of two therapy co-operative groups was 0.002. There were 37 patients(56.9%)using TX and 28(43.1%)using NX in therapy co-operative group A. There were 39 patients (72.2%)using TX, 9(16.7%)using NX and 6(6%) using regimen containing xeloda in therapy co-operative group B. Progression-free survival was 8 months in patients who follow by xeloda and 12 months in those who follow by endocrine (p & lt;0.01).Conclusion Endocrine therapy after xeloda-contained chemotherapy regimen tend to be more effective than single xeloda therapy for patients with HER-2 negative, HR positive. This results request to be verified by advanced OS data, which was needed to in-depth study in clinic and explore relevant biological indicators.

    Abstract: Background: Everolimus (EVE), an inhibitor of mammalian target of rapamycin (mTOR), is a protein kinase central to a number of signaling pathways regulating cell growth and proliferation. In early studies, EVE showed antitumor activity in breast cancer and synergy with both trastuzumab (TRAS) and paclitaxel. The international BOLERO-1 study is being conducted to evaluate the addition of EVE to TRAS plus paclitaxel as first-line therapy for HER2+ advanced breast cancer. Methods: In this phase 3 randomized trial, 719 adult women with HER2+ advanced breast cancer who had not received prior TRAS or chemotherapy in the advanced setting were randomized 2:1 to receive either EVE or placebo (10 mg) in combination with weekly paclitaxel and TRAS. The two primary objectives were to compare the progression-free survivals (PFS) of everolimus/trastuzumab/paclitaxel and trastuzumab/paclitaxel/placebo in both the full population and in the Hormone Receptor negative (HR-) subpopulation. Secondary endpoints included survival, response rate, and safety. The final analysis was performed after 420 PFS events were observed in the full population. Results: In the full population, the median age was 53 years, 70.4% had visceral metastases, 56.1% had ER and/or PgR +ve disease, and 43.3% had ≥ 3 metastatic sites. Previous adjuvant therapy included TRAS (11.4%) and taxane (24.7%). Conclusions: The data from the final analysis will be available in October 2014. PFS, safety, and secondary efficacy endpoints will be presented at SABCS 2014. (Funded by Novartis; BOLERO-1 ClinicalTrials.gov number, NCT00876395.)

    Abstract: Background: In the phase III MONARCH plus study (NCT02763566) the cyclin-dependent kinase (CDK) 4 & 6 inhibitor abemaciclib in combination with non-steroidal aromatase inhibitors (NSAI) or with fulvestrant compared with placebo demonstrated its efficacy and acceptable safety profile at interim analysis in postmenopausal women with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) locoregionally recurrent or metastatic breast cancer. One of the most common treatment-emergent adverse event (TEAE) was diarrhea, typically low grade and of early onset. We will further characterize abemaciclib-associated diarrhea and describe its management in MONARCH plus trial. Methods: MONARCH plus study included two cohorts of patients. Cohort A enrolled patients with initial treatment of endocrine therapy, received abemaciclib or placebo plus NSAI (anastrozole or letrozole); Cohort B enrolled patients who progressed on prior endocrine therapy, receiving abemaciclib or placebo plus fulvestrant. The relative dose intensity was defined as the percentage of actual dose received relative to the planned dose. The severity of diarrhea was reported by investigators and graded according to Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE v4.0). Further analysis on diarrhea included time to onset, duration, supportive medication and dose modifications. Progression-free survival (PFS) was defined as time from randomization to death or progression (RECIST v1.1), and a stratified Cox proportional hazard model was used to estimate the hazard ratio (HR) between study intervention arm and placebo arm. Results: The median relative dose intensity of abemaciclib in abemaciclib plus NSAI arm and abemaciclib plus fulvestrant arm were 96.77% and 96.30% respectively. In abemaciclib plus NSAI arm and abemaciclib plus fulvestrant arm, the median time to onset of first reported diarrhea was 7 and 6 days and majority of diarrhea events occurred early (66.3% and 71.2% of patients reported diarrhea in Cycle 1 respectively). Diarrhea was typically of low grade (3.9% and 1.9% of patients reported Grade 3 in abemaciclib plus NSAI arm and abemaciclib plus fulvestrant arm, no Grade 4 diarrhea was reported in either arm). Median duration of grade ≥ 3 diarrhea was 2.5 and 3.5 days. Diarrhea was managed by dose adjustments and/or supportive medication (Table 1). Dose reductions were present in 2.0% and 2.9% of patients, and anti-diarrhea therapy was received in 30.2% and 32.7% of patients with abemaciclib plus NSAI and abemaciclib plus fulvestrant arm, respectively. As data cutoff, most diarrhea events were reported as resolved, and the incidence dropped below 10% (Grade 2) and 1% (Grade 3) by Cycle 2 in both arms and kept low incidence over time. Compared to the placebo arm, patients treated with abemaciclib combination who reported diarrhea within the first 7 days (abemaciclib + NSAI, HR [95% CI]: 0.289 [0.166, 0.502] ; abemaciclib + fulvestrant, HR [95% CI]: 0.371 [0.213, 0.647] ) had significant improvement in PFS. Conclusion: Majority of diarrhea events were of low grade in severity and well managed by anti-diarrheal medications, dose omissions or/and dose reductions in MONARCH plus patients. Table 1.

    Abstract: Background The outbreak of COVID-19 pandemic in China has greatly impacted the radiotherapy (RT) strategy for breast cancer (BC) patients, which might lead to an increased distressing psychological symptom. Thus, we perform a multi-center cross-section survey aiming to investigate the prevalence of fears of cancer recurrence (FCR) and explore predictors for FCR in BC patients referred for RT during pandemic. Methods: 542 BC patients who referred for RT between 24th Jan and 30th April 2020 during pandemic were consecutively enrolled from 14 hospitals around China including Yangtze Delta River Region, Guangdong and Shanxi province. Patients’ sociodemographic, treatment information as well as psychological characteristics were collected using an information sheet, Fear of progression questionnaire-short form (FoP-Q-SF), Hospital Anxiety and Depression Scale (HADS) and EORTC QLQ-C30. The influence of pandemic on RT schedule was divided into four categories: “delay” was defined as & gt;12 weeks from surgery to RT in patients without chemotherapy or & gt;8 weeks from last time of anti-tumor therapy (including chemotherapy and surgery) to RT in patients with chemotherapy; “Special normal” was defined that patients themselves believed to have delayed RT initiation but actually not; “Interruption” was defined as any unplanned gaps in original RT regime and all other would be classified into “normal”. Another type of influence on RT strategy was that patients had to shift planned RT hospital from Grade-A tertiary hospital to local hospitals. Univariable analyses of FCR were performed in a one-way analysis of variance (ANOVA) or student t-test or Pearson correlation analyses and candidate variables with P & lt;0.2 were included Hierarchical multiple regression models to investigate predictors for FCR. Guangdong province was chosen as reference in models. Results 488 patients with complete data were eligible for the present analysis and none of patients and their family members had been diagnosed as COVID-19. The RT strategy was affected in 265 (54.3%) patients, including 143 with delayed RT initiation, 66 with “special normal” schedule, 24 (4.9%) with RT interruptions, 19 shifting to local hospitals for RT, and the remaining 13 being influenced on both RT schedule and planned RT hospitals. Most of patients with affected RT strategy occurred in late January and February, when was peak of COVID-19 pandemic in China. The mean FCR scores was 24.83 (SD=8.554) and 84 patients (17.3%) were classified as dysfunctional level of FCR (sum score ≥34). In univariable analyses, FCR were significantly higher in patients who received RT in Guangdong province and in hospitals with & lt; 100 BC cases per year. In term of during pandemic, a significant difference in FCR was observed in terms of influence on RT schedule (p & lt;0.001). and changes of hospital levels(p=0.009). There were significant correlations between FCR and anxiety/depressive in HADS or all five function scales (physical, role, emotional, cognitive and social) and global QoL in QLQ-C30 (p & lt;0.001). Finally, the model explained 59.7% of observed variances in FCR and showed that influence of RT strategy during pandemic had significantly impacted on FCR (ΔR2=0.01, ΔF=2.966, p=0.019). Hospitals in Shanxi province (β=-0.117, p=0.001), emotional function (β=-0.19, p & lt;0.001), social function (β=-0.111, p=0.006), anxiety (β=0.434, p & lt;0.001) and RT interruption (β=0.071, p=0.035) were independent predictors for FCR. Conclusions RT strategy for BC patients was greatly influenced during pandemic. RT interruption is an independent predictor for high FCR. Our findings emphasize the necessity to ensure the continuum of RT in BC patients, and efforts should be taken to alleviate the FCR through psychological interventions.
