Using the National Cancer Data Base for quality evaluation to assess adherence to treatment guidelines for nonmetastatic inflammatory breast cancer

Hospital Volume Predicts Guideline-Concordant Care in Stage III Esophageal Cancer

BACKGROUND

Esophageal cancer is a deadly disease requiring multidisciplinary coordination of care and surgical proficiency for adequate treatment. We hypothesize that quality of care is varied nationally.

METHODS

From published guidelines, we developed quality measures for management of stage III esophageal cancer: utilization of neoadjuvant therapy, surgical sampling of at least 15 lymph nodes, resection within 60 days of chemotherapy or radiation, and completeness of resection. Measure adherence was examined across 1345 hospitals participating in the National Cancer Database from 2004 to 2016. We examined the association of volume, program accreditation, safety net status, geographic region, and patient travel distance on adequate adherence (≥85% of patients are adherent) using logistic regression modeling.

RESULTS

The rate of adequate adherence was worst in nodal staging (12.6%) and highest for utilization of neoadjuvant therapy (84.8%). Academic programs had the highest rate of adequate adherence for induction therapy (77.2%; P < .001), timing of surgery (56.6%; P < .001), and completeness of resection (78.5%; P < .001) but the lowest for nodal staging (4.4%; P = .018). For every additional esophagectomy performed per year, the odds of adequate adherence increased for induction therapy (odds ratio [OR]. 1.16; 95% confidence interval [CI], 1.06-1.27) and completeness of resection (OR, 1.15; 95% CI, 1.06-1.25) but decreased for nodal staging (OR, 0.76; 95% CI, 0.65-0.89).

CONCLUSIONS

Care provided at higher volume and academic facilities was more likely to be guideline concordant in some areas but not in others. Understanding the processes that support the delivery of guideline concordant care may provide valuable opportunities for improvement.

Guideline-Consistent Treatment for Inflammatory Breast Cancer Provides Associated Survival Benefit Independent of Age

BACKGROUND

Guideline-consistent treatment (GCT) for inflammatory breast cancer (IBC) includes neoadjuvant chemotherapy (NAC), modified radical mastectomy (MRM), and radiation. We hypothesized that younger patients more frequently receive GCT, resulting in survival differences.

METHODS

Using the National Cancer Database (2004-2018), female patients with unilateral IBC (by histology code and clinical stage T4d) were stratified by age (< 50, 50-65, > 65 years). Factors associated with NAC, MRM, radiation, and "GCT" (defined as all three treatments) were identified using multivariable logistic regression. Multivariable Cox proportional hazards regression identified predictors of overall survival.

RESULTS

Of 3278 IBC patients, 30% were younger than 50 years, 44% were 50-65 years of age, and 26% were older than 65 years. The youngest group comprised the greatest proportion of non-White patients ([35%] vs. [29%] age 50-65 years and [23%] age > 65 years, p < 0.001) and was most often treated at academic facilities ([33%] vs. [28%] age 50-65 years; and [23%] age > 65, p < 0.001). Patients older than 65 years received NAC, MRM, and radiation less frequently, and only 35% underwent GCT (vs. [57%] age 50-65 years and [52%] age < 50 years; p < 0.001). On multivariable logistic regression, age older than 65 years independently predicted omission of NAC (odds ratio [OR], 0.36), MRM (OR, 0.56), and radiation (OR, 0.56) (all p < 0.001), and patients older than 65 years also were less likely to undergo GCT than patients 50-65 years of age (OR, 0.65; p = 0.001). GCT was associated with superior overall survival in all three age groups ([hazard ratio {HR}, 0.61] age < 50 years, [HR, 0.62] age 50-65 years, [HR, 0.53] age > 65 years; all p < 0.001).

CONCLUSION

Advanced age alone should not limit receipt of GCT for IBC. Multimodal care should be performed for IBC patients of all ages to improve oncologic outcomes for this aggressive breast cancer subtype.

Trends, survival outcomes, and predictors of nonadherence to mastectomy guidelines for nonmetastatic inflammatory breast cancer

BACKGROUND

The Current National Comprehensive Cancer Network guidelines recommend modified radical mastectomy (MRM) as the surgical treatment of choice for nonmetastatic inflammatory breast cancer (IBC). Limited studies have looked into the outcomes of breast conserving surgery (BCS) vs. MRM for IBC.

METHODS

National Cancer Database (NCDB) data from 2004 to 2014 were retrospectively analyzed. Patients' demographics, tumor characteristics, and overall survival (OS) trends were compared for BCS and MRM cases of nonmetastatic IBC. Univariate and multivariate analyses were performed.

RESULTS

A total of 413 (3.89%) BCS and 10,197 (96.11%) MRM cases were identified. Median follow-up was 58.45 months. Compared to MRM, BCS patients were more likely to be older, be African American, have Medicare/Medicaid or be uninsured, live in lower education ZIP codes, and live in a metropolitan area (all p < 0.05). BCS rates significantly decreased from 5.84% in 2004 to 3.19% in 2014 (p < 0.001). BCS patients also were more likely to have less than 50% of the breast involved (51.57% vs. 43.88%; p = 0.0081) and were less likely to receive trimodal therapy (50.85% vs. 74.62%; p = <0.0001). The OS was significantly higher in the mastectomy group over 9 years at 62.02% vs. 54.47% in the BCS group. Additionally, in the adjusted multivariate model, BCS cases were associated with 23% higher hazards of overall mortality (p = 0.0091).

CONCLUSION

BCS was performed in a limited number of cases, which decreased over the study period. The analysis identified both demographic predictors of receiving BCS and significantly lower OS for IBC patients undergoing a BCS.

Adherence to quality measures improves survival in esophageal cancer in a retrospective cohort study of the national cancer database from 2004 to 2016

Background

We assessed adherence to four novel quality measures in patients with stage III esophageal cancer, a leading cause of death among GI malignancies.

Methods

We performed a retrospective cohort study of 22,871 stage III esophageal cancer patients identified from the National Cancer Database (NCDB) between 2004 and 2016. Four quality measures were defined from published guidelines: administration of induction therapy, >15 lymph nodes sampled, surgery within 60 days of neoadjuvant treatment, and R0 resection. The association of patient demographic and treatment variables with measure adherence was assessed using multiple logistic regression. Risk of all-cause mortality was assessed comparing adherent and non-adherent cases using Cox modeling. Kaplan-Meier survival estimates of groups that adhered to zero to four out of four quality measures were performed.

Results

Adherence was high for neoadjuvant treatment (93.7%), timing of surgery (85.7%) and completeness of resection (92.0%), but low for nodal evaluation (45.9%). Medicaid insurance status was associated with decreased odds of adherence for neoadjuvant treatment [odds ratio (OR) 0.73, 95% confidence interval (CI): 0.54–0.99], nodal evaluation (OR 0.81, 95% CI: 0.68–0.96), and completeness of resection (OR 0.71, 95% CI: 0.54–0.92). From 2010 to 2016, when compared to cases from 2004 to 2005, there was a progressive increase in the odds of adequate induction therapy, nodal staging, and completeness of resection, but a progressive decrease in odds of well-timed surgery. Adherence was associated with decreased all-cause mortality for induction therapy, nodal staging, and R0 resection, but not for timing of surgery. Survival improved as the number of quality measures an individual patient adhered to increased.

Conclusions

Adherence to quality measures is associated with improved survival in patients with stage III esophageal cancer. Understanding variability in measure adherence may identify targets for quality improvement initiatives.

Locoregional Management of Inflammatory Breast Cancer

Purpose of Review

Inflammatory breast cancer (IBC) is a biologically aggressive subtype with a high risk for rapid local progression and early distant metastasis. We review the updated data for optimal locoregional management of IBC, including areas of active controversy.

Recent Findings

Advancements in tri-modality therapies have improved survival among IBC patients in recent years; however, the risk of locoregional and distant recurrence remains high, particularly in triple-negative IBC. Data to support de-escalation of surgery or radiotherapy is limited, and the recommended treatment approach for non-metastatic IBC remains preoperative systemic therapy (PST), modified radical mastectomy (MRM), and adjuvant radiotherapy in all patients. For patients with de novo metastatic disease, locoregional intervention may be appropriate.

Summary

Optimal locoregional management of IBC remains PST followed by MRM and adjuvant radiotherapy. With increasingly effective systemic therapies, research to identify a subset of patients who may benefit from de-escalation of locoregional therapies is warranted.

Patient and physician factors associated with Oncotype DX and adjuvant chemotherapy utilization for breast cancer patients in New Hampshire, 2010-2016

BACKGROUND

Oncotype DX® (ODX) is used to assess risk of disease recurrence in hormone receptor positive, HER2-negative breast cancer and to guide decisions regarding adjuvant chemotherapy. Little is known about how physician factors impact treatment decisions. The purpose of this study was to examine patient and physician factors associated with ODX testing and adjuvant chemotherapy for breast cancer patients in New Hampshire.

METHODS

We examined New Hampshire State Cancer Registry data on 5630 female breast cancer patients diagnosed from 2010 to 2016. We performed unadjusted and adjusted hierarchical logistic regression to identify factors associated with a patient's receipt of ODX, being recommended and receiving chemotherapy, and refusing chemotherapy. We calculated intraclass correlation coefficients (ICCs) to examine the proportion of variance in clinical decisions explained by between-physician and between-hospital variation.

RESULTS

Over the study period, 1512 breast cancer patients received ODX. After adjustment for patient and tumor characteristics, we found that patients seen by a male medical oncologist were less likely to be recommended chemotherapy following ODX (OR = 0.50 (95% CI = 0.34-0.74), p < 0.01). Medical oncologists with more clinical experience (reference: less than 10 years) were more likely to recommend chemotherapy (20-29 years: OR = 4.05 (95% CI = 1.57-10.43), p < 0.01; > 29 years: OR = 4.48 (95% CI = 1.68-11.95), p < 0.01). A substantial amount of the variation in receiving chemotherapy was due to variation between physicians, particularly among low risk patients (ICC = 0.33).

CONCLUSIONS

In addition to patient clinicopathologic characteristics, physician gender and clinical experience were associated with chemotherapy treatment following ODX testing. The significant variation between physicians indicates the potential for interventions to reduce variation in care.

Origin-destination flows in chemotherapy for breast cancer in Brazil: implications for pharmaceutical services

Abstract This study maps and analyzes patient flows for breast cancer chemotherapy in order to identify the potential implications for organization of pharmaceutical services in the cancer care network. An ecological study design sought to correlate the place of residence with place of care for breast cancer patients. All chemotherapy procedures financed by Brazil’s Unified Health System (SUS) and performed from January to December 2013 were included. Flows were mapped using TerraView® software. A total of 1 347 803 outpatient chemotherapy procedures were delivered by 243 cancer care units located in 156 municipalities. Seventeen cities concentrated approximately 50.0 % of the procedures. A total of 8 538 origin-destination flows were generated and 49.2% of procedures were performed in services located outside the municipality in which the patient resided. Context challenges, related to inequality of access to chemotherapy and hindrances in planning and management of pharmaceutical services, were discussed.

Tertiary care centre adherence to unified guidelines for management of periprosthetic joint infections: a gap analysis

BACKGROUND

The success rate of surgical treatment for periprosthetic joint infection (PJI) remains inconsistent in the literature. Variability in PJI clinical guidelines and surgeon adherence to guidelines could affect treatment success. The objectives of this study were to appraise current recommendations for PJI management and develop a unified clinical standard of care, to perform a gap analysis of PJI cases in a tertiary institution to determine the rate of guideline adherence, and to determine if adherence to unified PJI guidelines affected 2-year treatment outcomes.

METHODS

We appraised the PJI guidelines from 3 academic medical societies, and consistent statements were aggregated. We retrospectively reviewed all PJI cases in a tertiary care institution. We defined PJI based on Musculoskeletal Infection Society PJI criteria. Surgeon adherence to preoperative, intraoperative, surgical and medical management guidelines was calculated, and we evaluated the association between guideline adherence and 2-year treatment outcomes.

RESULTS

The institutional rate of PJI was 1.13% (38 of 3368). Treatment success was 57.8% at 2 years. Unified guideline adherence percentages varied substantially: 92% of patients had preoperative erythrocyte sedimentation rate and C-reactive protein, 97% had intraoperative tissue cultures, 42% had appropriate preoperative arthrocentesis, and 74% underwent guideline-appropriate surgery. Performing appropriate preoperative arthrocentesis significantly correlated with positive treatment outcomes at 2 years (p = 0.028).

CONCLUSION

Adherence to PJI guidelines varies considerably, indicating that clinicians are either unaware of them or do not recognize their value for PJI treatment. This study shows the need for institution-based PJI treatment pathways that are consistent with published guidelines and the need to monitor adherence.
