Survivorship care visits in a high-risk population of breast cancer survivors

Predictors and impact of survivorship care plans and survivorship care visits

PURPOSE

We performed this study to characterize the population at the Lifespan Cancer Institute (LCI) who received a survivorship care plan (SCP) with or without a survivorship care visit (SCV) to determine both the impact on specialty referrals and the demographic and clinical predictors of SCPs and SCVs.

METHODS

We retrospectively reviewed EMR records on 1960 patients at LCI between 2014 and 2017 for SCPs and SCVs and extracted demographics, distress thermometer (DT) scores collected at the time of initial presentation, and subsequent referrals. We evaluated the bivariate associations of SCP and SCV with continuous and categorical factors and assessed the adjusted effect of these factors on receipt of SCP and SCV independently. All analyses were performed in R v4.0.2.

RESULTS

SCPs were completed in 740 (37.8%) patients, and of those, 65.9% had a SCV. The mean age was 63.9, 67% were female, and 51.2% were married or partnered. Patients treated for breast, lung, and prostate cancers most received an SCP. Compared to SCP alone, the SCV was associated with more specialty referrals. Those who were younger and had breast cancer were more likely to receive a SCP, and those who were younger and female and had breast cancer were more likely to receive a SCV.

CONCLUSIONS

Gender, age, and type of cancer are significant predictors of receipt of SCP and SCV. Patients who received either SCP, SCV, or both were more likely to receive specialty referrals than those who received neither.

IMPLICATIONS FOR CANCER SURVIVORS

Identifying predictive factors of SCP and SCV can help facilitate earlier receipt of specialty services and specialty referrals as needed.

Late effects in a high-risk population of breast cancer survivors

PURPOSE

To better understand the impact of cancer and treatment on outcomes and guide program development, we evaluated breast cancer survivors at risk for long-term medical and psychosocial issues who participated in survivorship care visits (SVs) at Johns Hopkins Hospital.

METHODS

We conducted a prospective survey study of women with stage I-III breast cancer who participated in SVs from 2010-2016. The same 56-item questionnaire administered at SV and follow-up included an assessment of symptoms, social factors, demographics, anxiety, depression, and comorbidities. We added the Godin Exercise questionnaire to the follow-up.

RESULTS

In 2018, 74 participants were identified as disease-free and mailed a follow-up survey; 52 (70.3%) completed the survey. At a median follow-up time of 3.1 years after diagnosis, participants were less likely to be employed (54% vs. 67%) than at the SV. About two-thirds were sedentary, and this was associated with high body mass index (p = 0.02). Sufficiently active participants (≥ 150 min per week of moderate-intensity activity) were less likely to report pain (p = 0.02) or fatigue (p = 0.001). Although 19% had moderate/severe anxiety or depression at follow-up, participants who reported employment satisfaction were less likely to be depressed (p = 0.02).

CONCLUSIONS

Awareness of issues faced by survivors is critical for enhancing care and developing models to identify patients who might benefit most from targeted long-term interventions.

IMPLICATIONS FOR CANCER SURVIVORS

Interventions to address physical activity, persistent symptoms, and mental health are critical for breast cancer survivors.

Tumor-associated neutrophils activated by tumor-derived CCL20 (C-C motif chemokine ligand 20) promote T cell immunosuppression via programmed death-ligand 1 (PD-L1) in breast cancer

Breast cancer is the leading cause of cancer-related death among women despite the significant improvement in diagnosis and treatment. Tumor-associated neutrophils have been shown to suppress antitumor functions of the host. However, how breast cancer tumor microenvironment influences the phenotype and functions of neutrophils to potentiate T cell immunosuppression is unknown. Herein, neutrophils isolated from peripheral blood of healthy donors were treated with supernatants from breast cancer cell lines or recombinant human CCL20. PD-L1 expression on neutrophils was then evaluated by immunofluorescence and flow cytometry. Neutrophils and Jurkat T cells were cocultured to evaluate the effect of tumor-associated neutrophils on T cell functions. Finally, immunohistochemical staining was performed to evaluate the clinical relevance of neutrophils infiltrating breast tumor tissues. Tumor-derived CCL20 activated and upregulated PD-L1 expression on neutrophils. A significant positive correlation was found between CCL20 and CD66b+ neutrophils in tumor tissues. Through in vitro experiment, tumor-associated neutrophils (TANs) effectively suppressed T cell immunity which was reversed upon PD-L1 blockade.Moreover, a high density of TANs was associated with short disease free survival in breast cancer patients. Furthermore, receiver operating curve showed that the density of TANs could accurately predict disease-free survival in breast cancer patients. Our findings suggest that targeting TANs via CCL20 immunosuppressive pathway may be a novel therapeutic strategy for breast cancer treatment.

Clinical importance of serum secreted clusterin in predicting invasive breast cancer and treatment responses

Enhanced serum secreted clusterin (sCLU) protein was associated with progression, poor prognosis and chemotherapy sensitivity evaluation in malignant patients. However, the clinical significance of serum sCLU protein levels in patients with invasive breast cancer (IBC) is unknown. In this study, the serum sCLU protein in 2648 patients with IBC was detected. The diagnostic value and treatment responses of serum sCLU protein in patients with IBC were also performed. The results showed that the serum sCLU protein level was significantly higher in IBC patients compared to the healthy controls (P < 0.0001), and strongly correlated with higher clinical tumor stage (P < 0.001), lymph node metastasis (P < 0.001), shorter overall survival (OS) (P = 0.032) and disease-free survival (DFS) (P = 0.029), respectively. Using the cutoff value of 18.46 μg/mL, the sensitivity and specificity were 86.26% and 73.46% to separate IBC patients from noncancerous and healthy controls. The postoperative patients showed lower serum sCLU levels compared to the preoperative patients (P = 0.003). The chemoresistant patients showed higher serum sCLU levels compared to the chemosensitive patients (P < 0.001). These data indicated that serum sCLU levels are effective indicators for diagnosis and chemotherapy sensitivity evaluation in patients with IBC.

The impact of monitoring techniques on progression to chronic breast cancer-related lymphedema: a meta-analysis comparing bioimpedance spectroscopy versus circumferential measurements

BACKGROUND

Chronic breast cancer-related lymphedema (BCRL) is a potentially serious complication following treatment. Monitoring for progression to BCRL may allow for earlier detection and intervention, reducing the rate of progression to chronic BCRL. Therefore, the purpose of this meta-analysis is to evaluate the impact of monitoring techniques on the incidence of chronic BCRL among patients monitored by bioimpedance spectroscopy (BIS) and circumference as compared to background rates.

METHODS

Eligible peer-reviewed studies from PubMed, CINHAL, or Google Scholar that were published in English from 2013 onward and conducted in North America, Europe, or Oceania. Incidence rates abstracted from studies were classified by BCRL monitoring method: background (no standardized BIS or circumference assessments), BIS or circumference. A random-effects model was used to calculate a pooled annualized estimate of BCRL incidence while accounting for clinical and methodological heterogeneity. Subgroup analyses examined differences in duration of follow-up as well as breast and axillary surgery.

RESULTS

50 studies were included, representing over 67,000 women. The annualized incidence of BCRL was 4.9% (95% CI: 4.3-5.5) for background studies (n = 35), 1.5% (95% CI: 0.6-2.4) for BIS-monitored studies (n = 7), and 7.7% (95% CI: 5.6-9.8) for circumference-monitored studies (n = 11). The cumulative BCRL incidence rate in BIS-monitored patients was 3.1% as compared to 12.9% with background monitoring (69% reduction) and 17.0% with circumference-monitored patients (81% reduction).

CONCLUSIONS

Evidence suggests that monitoring with BIS allowing for early intervention significantly reduces the relative risk of chronic BCRL with a 69% and 81% reduction compared to background and circumference, respectively. Circumference monitoring did not appear to provide a benefit with respect to chronic BCRL incidence. Based on these results, BIS should be considered for BCRL screening in order to detect subclinical BCRL and reduce rates of chronic BCRL, particularly in high-risk patients.
