Impact of Time to Initiation of Treatment on the Quality of Life of Women with Breast Cancer

Impact of Preoperative Time Intervals for Neoadjuvant Chemoradiotherapy on Short-term Postoperative Outcomes of Esophageal Cancer Surgery: A Population-Based Study Using the Dutch Upper Gastrointestinal Cancer Audit (DUCA) Data

OBJECTIVE

To clarify the impact of the preoperative time intervals on short-term postoperative and pathological outcomes in esophageal cancer patients who underwent neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy.

SUMMARY BACKGROUND DATA

The impact of preoperative intervals on esophageal cancer patients who received multimodality treatment remains unknown.

METHODS

Patients(cT1-4aN0-3M0) treated with nCRT plus esophagectomy were included using the Dutch national DUCA-database. Multivariate logistic regression was used to determine the effect of different time intervals upon short-term postoperative and pathological outcomes: diagnosis-to-nCRT intervals (≤5, 5-8 and 8-12 wk), nCRT-to-surgery intervals (5-11, 11-17 and >17 wk) and total preoperative intervals (≤16, 16-25 and >25 wk).

RESULTS

Between 2010-2021, a total of 5052 patients were included. Compared to diagnosis-to-nCRT interval ≤5 weeks, the interval 8-12 weeks was associated with higher risk of overall complications (P=0.049). Compared to nCRT-to-surgery interval 5-11 weeks, the longer intervals (11-17 wk and >17 wk) were associated with higher risk of overall complications (P-value=0.016; P-value<0.001) and anastomotic leakage (P-value=0.004; P-value=0.030), but the interval >17 weeks was associated with lower risk of ypN+ (P-value=0.021). The longer total preoperative intervals were not associated with the risk of 30-day mortality and complications compared to the interval ≤16 weeks, but the longer total preoperative interval (>25 wk) was associated with higher ypT stage (P-value=0.010) and lower pCR rate (P-value=0.013).

CONCLUSION

In patients with esophageal cancer undergoing nCRT and esophagectomy, prolonged preoperative time intervals may lead to higher morbidity and disease progression, and the causal relationship requires further confirmation.

Association of Race, Ethnicity, Language, and Insurance with Time to Treatment Initiation Among Women with Breast Cancer at an Urban, Academic, Safety-Net Hospital

INTRODUCTION

Initial treatment for nonmetastatic breast cancer is resection or neoadjuvant systemic therapy, depending on tumor biology and patient factors. Delays in treatment have been shown to impact survival and quality of life. Little has been published on the performance of safety-net hospitals in delivering timely care for all patients.

METHODS

We conducted a retrospective study of patients with invasive ductal or lobular breast cancer, diagnosed and treated between 2009 and 2019 at an academic, safety-net hospital. Time to treatment initiation was calculated for all patients. Consistent with a recently published Committee on Cancer timeliness metric, a treatment delay was defined as time from tissue diagnosis to treatment of greater than 60 days.

RESULTS

A total of 799 eligible women with stage 1-3 breast cancer met study criteria. Median age was 60 years, 55.7% were non-white, 35.5% were non-English-speaking, 18.9% were Hispanic, and 49.4% were Medicaid/uninsured. Median time to treatment was 41 days (IQR 27-56 days), while 81.1% of patients initiated treatment within 60 days. The frequency of treatment delays did not vary by race, ethnicity, insurance, or language. Diagnosis year was inversely associated with the occurrence of a treatment delay (OR: 0.944, 95% CI 0.893-0.997, p value: 0.039).

CONCLUSION

At our institution, race, ethnicity, insurance, and language were not associated with treatment delay. Additional research is needed to determine how our safety-net hospital delivered timely care to all patients with breast cancer, as reducing delays in care may be one mechanism by which health systems can mitigate disparities in the treatment of breast cancer.

Differences in the association of time to treatment initiation and survival according to various head and neck cancer sites in a nationwide cohort

OBJECTIVES

To assess whether there are differences in the effects of time to treatment interval (TTI) on patient survival for head and neck cancer (HNC) sites in order to provide evidence that can support decision-making regarding prioritizing treatment.

MATERIALS AND METHODS

Patients in the Netherlands with a first primary HNC without distant metastasis between 2010 and 2014 were included for analysis (N = 10,486). TTI was defined as the time from pathologic diagnosis to the start of initial treatment. Overall survival (OS), cox regression analyses and cubic spline hazard models were calculated and visualized.

RESULTS

Overall, the hazard of dying was higher (HR = 1.003; 95 % CI 1.001-1.005) with each additional day until treatment initiation. The pattern, as visualized in cubic spline graphs, differed by site the hazard increased more steeply with increasing TTI for oral cavity cancer. For oropharyngeal and laryngeal cancer, a slight increase commenced after a longer TTI than for oral cavity cancer, while there was hardly an increase in hazard with increasing TTI for hypopharyngeal cancer.

CONCLUSION

The relationship between longer TTI and decreased survival was confirmed, but slight variations in the pattern of the hazard of dying by TTI by tumour site were observed. These findings could support decisions on prioritizing treatment. However, other aspects such as extent of treatment and quality of life should be investigated further so this can also be included.

Associations between health insurance status, neighborhood deprivation, and treatment delays in women with breast cancer living in Georgia

BACKGROUND

Little is known regarding the association between insurance status and treatment delays in women with breast cancer and whether this association varies by neighborhood socioeconomic deprivation status.

METHODS

In this cohort study, we used medical record data of women diagnosed with breast cancer between 2004 and 2022 at two Georgia-based healthcare systems. Treatment delay was defined as >90 days to surgery or >120 days to systemic treatment. Insurance coverage was categorized as private, Medicaid, Medicare, other public, or uninsured. Area deprivation index (ADI) was used as a proxy for neighborhood-level socioeconomic status. Associations between delayed treatment and insurance status were analyzed using logistic regression, with an interaction term assessing effect modification by ADI.

RESULTS

Of the 14,195 women with breast cancer, 54% were non-Hispanic Black and 52% were privately insured. Compared with privately insured patients, those who were uninsured, Medicaid enrollees, and Medicare enrollees had 79%, 75%, and 27% higher odds of delayed treatment, respectively (odds ratio [OR]: 1.79, 95% confidence interval [CI]: 1.32-2.43; OR: 1.75, 95% CI: 1.43-2.13; OR: 1.27, 95% CI: 1.06-1.51). Among patients living in low-deprivation areas, those who were uninsured, Medicaid enrollees, and Medicare enrollees had 100%, 84%, and 26% higher odds of delayed treatment than privately insured patients (OR: 2.00, 95% CI: 1.44-2.78; OR: 1.84, 95% CI: 1.48-2.30; OR: 1.26, 95% CI: 1.05-1.53). No differences in the odds of delayed treatment by insurance status were observed in patients living in high-deprivation areas.

DISCUSSION/CONCLUSION

Insurance status was associated with treatment delays for women living in low-deprivation neighborhoods. However, for women living in neighborhoods with high deprivation, treatment delays were observed regardless of insurance status.

Cyclin-dependent kinase 4/6 inhibitor treatment use in women treated for advanced breast cancer: Integrating ASCO/NCODA patient-centered standards in a community pharmacy

BACKGROUND

Outpatients treated with oral anti-cancer drugs, including selective cyclin-dependent kinase 4/6 inhibitors (CDK4/6i), may benefit from a pharmacy practice setting adapted to support proper oral anti-cancer drug monitoring. This real-world study aimed to characterize patient-centered pharmacy practice aligned with American Society of Clinical Oncology (ASCO)/National Community Oncology Dispensing Association (NCODA) standards and to describe its impact on CDK4/6i treatment use.

METHODS

This retrospective study included women with confirmed hormone receptor-positive/human epidermal growth factor 2 negative locally advanced or metastatic breast cancer treated with either palbociclib, abemaciclib or ribociclib combined with letrozole or fulvestrant. Pharmacists collected patient characteristics, clinical activities, and treatment patterns using data from the pharmacy chart. CDK4/6i treatment adherence rates were estimated based on medication claims data. Time-to-treatment discontinuation, a proxy for time-to-event, was assessed using the Kaplan-Meier estimate.

RESULTS

Of the 195 patients assessed for eligibility, 65 were included in this study. The median observation duration was 13.6 months. An average of seven pharmaceutical care activities (range 2.8-21.7) per patient was documented for each treatment cycle. The mean proportion of days covered was 89.6%. The median time-to-treatment discontinuation was estimated at 44.2 months in patients treated with CDK4/6i + letrozole and 17.0 months in patients treated with CDK4/6i + fulvestrant. The average relative dose intensity was 85%, and the benefits of treatment were maintained regardless of the relative dose intensity levels.

CONCLUSION

A structured patient-centered pharmacy practice model integrating the ASCO/NCODA patient-centered standards and ongoing communication with patients and healthcare providers ensure timely refills, close monitoring, and allows patients to achieve high adherence and persistence rates comparable to those reported in clinical trials.

Association of treatment delay and stage with mortality in breast cancer: a nationwide cohort study in Taiwan

Breast cancer is the fifth leading cause of cancer death globally. In this retrospective study, we investigated the effects of the diagnosis-to-first-treatment interval (DFTI) and other related factors on cancer-specific survival in patients with breast cancer. We included 49,426 patients newly diagnosed as having breast cancer during 2011-2017. The Cox proportional hazards model was used to analyze the hazard ratio (HR) for mortality with various DFTIs; the HRs of the 31-60-, 61-90-, and ≥ 91-day DFTI groups did not differ significantly compared with the reference group (DFTI ≤ 30 days). After stratifying the patients according to initial tumor stage and age, we found that patients aged 55-64 and ≥ 65 years with stage II breast cancer treated ≥ 91 days after diagnosis had a 3.34- and 2.93-fold higher mortality risk (95% confidence intervals [CIs] 1.29-8.69 and 1.06-8.10, respectively). Patients aged ≥ 65 years with stage IV breast cancer treated within 61-90 or ≥ 91 days after diagnosis had a 7.14- and 34.78-fold higher mortality risk (95% CIs 1.28-39.82 and 3.08-393.32, respectively). In conclusion, DFTI is associated with mortality in patients with stage II and IV breast cancer, especially at an older age.

Association of Handgrip Strength with Quality of Life in Breast Cancer Survivors: A Systematic Review and Meta-Analysis

OBJECTIVE

Handgrip strength (HGS) is an indicator of general muscular strength and in cancer patients acts as a relevant marker associated with mortality and health. This study aimed to evaluate the association between peripheral muscle function and health-related quality of life (HRQoL) in breast cancer (BC) survivors.

METHODS

Systematic review registered on PROSPERO under number: CRD 42021225206. The searches were carried out on MEDLINE via Pubmed, PEDro, Cochrane Library, Embase, CINAHL via EBSCO and Science Direct databases. Observational studies evaluating the association between handgrip strength (HGS) and HRQoL in adult female BC survivors were included. No linguistic or time restrictions were applied. Two reviewers reviewed full texts for inclusion and performed data extraction and risk of bias using the Newcastle and Ottawa scale (NOS).

RESULTS

Five articles were included and involved 587 patients, mean age of 47 to 59 years. The percentage of decreased HGS ranged from 38.3% to 60.3%. HGS was associated with different quality of life measures. From meta-analysis including 220 patients, the correlation coefficient between HGS and HRQoL was 0.26 (95% CI: 0.07-0.35).

CONCLUSIONS

Breast cancer survivors face decline of HGS. In this population HGS was correlated with HRQoL. However, more evidence are necessary.

Analysis of the Effect of Trastuzumab Combined with Docetaxel on Serum Tumor Markers in the Treatment of HER-2 Positive Breast Cancer and Factors Influencing Therapeutic Efficacy

Objective

To explore the influence of trastuzumab (TZ) combined with docetaxel (DTX) on serum tumor markers (TMs) in the treatment of human epidermal growth factor receptor 2-positive (HER-2+) breast cancer (BC) and to analyze the factors influencing therapeutic efficacy.

Methods

Ninety-six patients with HER-2+ BC treated in the First Affiliated Hospital of Anhui University Of Science and Technology from January 2019 to December 2020 were selected. According to different treatment plans, the patients were divided into two arms with 48 cases each. The control group (CG) was treated with DTX, and the research group (RG) was given TZ combined with DTX (TZ+DTX). The two arms were compared regarding the following aspects: curative effects, adverse reaction, alterations of TMs and inflammatory factors (IFs), and quality of life. Logistic regression analysis was performed to analyze the factors affecting the efficacy of patients.

Results

After treatment, the TMs carcinoembryonic antigen (CEA), carbohydrate antigen (CA)125 and CA15-3 were significantly lower in RG compared with CG. The levels of IFs C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) were also lower in CG. The overall response rate and the Karnofsky performance status (KPS) score were significantly higher in RG. No evident difference was observed in the total incidence of adverse reactions between the two arms. The high expression of CEA, CA125 and CA15-3 as well as DTX monotherapy increased the risk of adverse prognosis.

Conclusion

TZ+DTX can effectively improve the clinical efficacy of HER-2+ BC patients and reduce their levels of serum TMs and IFs.

Patient Satisfaction with Oncological Care during the SARS-CoV-2 Virus Pandemic

Recently, the outbreak of the SARS-CoV-2 virus and the COVID-19 pandemic significantly affected the health situation of the entire society and necessitated reorganization of health care including oncology. The objective of this study was to examine the perception of medical services by cancer patients during the pandemic and to identify the key elements influencing the level of satisfaction with oncological care. Of note, 394 patients diagnosed with cancer treated in inpatient oncology wards participated in the study (Poland). The diagnostic survey method was used. A survey questionnaire developed by the authors was used and validated the EORTC IN-PATSAT32 questionnaire. The calculations were made in Statistica 10.0 (Statsoft; 2011, Dell Inc., Round Rock, TX, USA). The average general level of satisfaction with oncological care in the study group was 80.77 out of a total score of 100, representing the highest level of satisfaction. Levels of satisfaction varied according to time since diagnosis (longer time-greater satisfaction) and were lower where treatment was delayed or perceived as disorganised. Nearly half of the respondents felt the threat of the SARS-CoV-2 infection, despite the fact that most of them believed that the hospital was well prepared to diagnose and treat cancer patients during the COVID-19 pandemic. Convincing patients about the proper preparation of health care for diagnostics and therapy is an important element influencing patient satisfaction with oncological care.
