RESUMO

BACKGROUND: Little is known about how screening facilities are meeting the requirements for the reimbursement of lung cancer screening from the Centers for Medicare & Medicaid Services (CMS), including 1) the collection and submission of data to the CMS-approved registry (American College of Radiology [ACR] Lung Cancer Screening Registry), 2) the verification of a counseling and shared decision-making (SDM) visit having occurred as part of the written order for lung cancer screening with low-dose computed tomography, and 3) the offering of smoking cessation interventions. METHODS: The authors identified facilities in a southwestern state that were listed by either the ACR Lung Cancer Screening Registry or the GO2 Foundation Centers of Excellence. To select facilities, they used 2 purposive sampling approaches: maximum variation sampling and snowball sampling. They surveyed facilities from February to November 2019. RESULTS: There were 87 facilities contacted, and a total of 63 facilities representing 32 counties across Texas completed the survey. Nearly all facilities used Lung-RADS to classify nodules (92%; n = 58) and submitted data to a CMS-approved registry (92%; n = 57). Most facilities verified that the counseling and SDM visit had occurred (86%; n = 54). Although slightly more than half of the facilities reported always providing self-help cessation materials (68%; n = 42), similar or higher proportions of facilities reported that they never referred smokers to onsite cessation services (68%; n = 42) or quitlines (77%; n = 47), provided cessation counseling (81%; n = 50), or recommended medications (85%; n = 52). CONCLUSIONS: In general, screening facilities are meeting CMS requirements for screening, but they are struggling to offer smoking cessation interventions other than providing self-help materials.

RESUMO

OBJECTIVE: to examine the geographic distribution of gynecologic oncologists (GO) and assess if the GO workforce is meeting the demand for oncology services for patients with gynecologic cancers. METHODS: We identified GO by National Provider Identifiers (NPI) and calculated county-level density of GO. County-level gynecologic cancer rates were derived from the U.S. Cancer Statistics to represent demand for GO services. A spatial data plot compared GO workforce to gynecologic cancer service demand. U.S. census county-level demographic information was collected and compared. RESULTS: In 2019, 1527 GO had a registered NPI. Of 3142 counties in the US, 2864 (91.2%) counties had no GO in their local county and 1943 (61.8%) counties had no GO in local or adjacent (neighboring) counties. As the gynecologic cancer rate increases (described in quintiles) in counties, there are fewer counties without a GO or adjacent GO. However, county-level GO density (number of GO per 100,000 women) did not significantly increase as the county-level incidence of gynecologic cancer increased (r = -0.12, p = 0.06)… Women living in counties with the highest gynecologic cancer rates and without access to a GO were more likely to reside in a rural area where residents had a lower median income and were predominately of White race.. CONCLUSION: There are a significant number of counties in the U.S. without a GO. As county-level gynecologic cancer incidence increased, the proportion of counties without a GO decreased; GO density did not increase with increasing cancer rates. Rural counties with high gynecologic incidence rates are underserved by GO. This information can inform initiatives to improve outreach and collaboration to better meet the needs of patients in different geographic areas.

RESUMO

BACKGROUND: Clinical practice guidelines for treating tobacco use and lung cancer screening guidelines recommend smoking cessation counseling to current smokers by health care professionals. OBJECTIVE: Our objective was to determine the contemporary patterns of current smokers' discussions about smoking with their health care professionals in the USA. DESIGN, SETTING, AND PARTICIPANTS: We conducted an observational study of 30,132 current smokers (weighted sample 40,126,006) for the years 2011 to 2015 using data from the National Health Interview Survey. MAIN MEASURES: Our main outcome was the proportion of current smokers who had discussions about smoking with their health care professionals. We used the Cochran-Armitage trend test to evaluate the temporal trends in current smokers' discussions about smoking, and used a multivariable logistic model to determine the predictors of discussions about smoking, controlling for smokers' demographics, health status, and receipts of lung cancer screening. KEY RESULTS: Our study found the proportion of current smokers who had discussions about smoking with their health care professionals increased from 51.3% in 2011 to 55.4% in 2015 (P-trend < 0.0001). However, about 15% of current smokers who underwent lung cancer screening did not have or could not recall discussions about smoking with their health care professionals. In multivariable analyses and sensitivity analysis, the predictors of discussions about smoking were being a heavy smoker, receipt of lung cancer screening, being non-Hispanic white, having a physician office visit in the past year, being diagnosed with respiratory conditions, having fair or poor health, and having insurance coverage. CONCLUSIONS: The results demonstrated a steady but slow increase in current smokers' discussions about smoking with their health care professionals in recent years, especially among heavy smokers. More than 40% of current smokers did not have or could not recall any discussions about smoking with their health care professionals.

RESUMO

BACKGROUND: We previously reported a significant volume-outcome relationship in mortality rates after gastrectomies for gastric cancer patients in Texas (1999-2001). We aimed to identify whether changes in the volume distribution of gastrectomies occurred, whether volume-outcome relationships persisted, and potential changes in the factors influencing volume-outcome relationships. METHODS: We performed a population-based study using the Texas Inpatient Public Use Data File between 2010 and 2015. Hospitals were classified as high-volume centers (HVCs, > 15 cases per year), intermediate-volume centers (IVCs, 3-15 cases per year), and low-volume centers (LVCs, < 3 cases per year). We conducted multivariate analyses to evaluate factors associated with inpatient mortality and adverse events. RESULTS: We identified 2733 gastric cancer patients who underwent gastrectomy at 193 hospitals. Fewer hospitals performed gastrectomy than previously (193 vs. 214). There were more HVCs (5 vs. 2) and LVCs (142 vs. 134), but fewer IVCs (46 vs. 78). The proportion of patients who underwent gastrectomy at HVCs and LVCs increased, while the proportion at IVCs decreased. HVCs maintained lower in-hospital mortality rates than IVCs or LVCs, although mortality rates decreased in both LVCs and IVCs. In adjusted multivariate analyses, treatment at HVCs remained a strong predictor for lower rates of mortality (odds ratio [OR] 0.39, p = 0.019) and adverse events (OR 0.56, p = 0.013). CONCLUSION: Despite improvements, patient morbidity and mortality at LVCs and IVCs remain higher than at HVCs, demonstrating that volume-outcome relationships still exist for gastrectomy and that opportunities for improvement remain.

RESUMO

OBJECTIVES: Given the uncertain cost of delivering community-based cancer screening programs, we developed a Markov simulation model to project the budget impact of implementing a comprehensive colorectal cancer (CRC) prevention program compared with the status quo. METHODS: The study modeled the impacts on the costs of clinical services, materials, and staff expenditures for recruitment, education, fecal immunochemical testing (FIT), colonoscopy, follow-up, navigation, and initial treatment. We used data from the Against Colorectal Cancer In Our Neighborhoods comprehensive CRC prevention program implemented in El Paso, Texas, since 2012. We projected the 3-year financial consequences of the presence and absence of the CRC prevention program for a hypothetical population cohort of 10,000 Hispanic medically underserved individuals. RESULTS: The intervention cohort experienced a 23.4% higher test completion rate for CRC prevention, 8 additional CRC diagnoses, and 84 adenomas. The incremental 3-year cost was $1.74 million compared with the status quo. The program cost per person was $261 compared with $86 for the status quo. The costs were sensitive to the proportion of high-risk participants and the frequency of colonoscopy screening and diagnostic procedures. CONCLUSIONS: The budget impact mainly derived from colonoscopy-related costs incurred for the high-risk group. The effectiveness of FIT to detect CRC was critically dependent on follow-up after positive FIT. Community cancer prevention programs need reliable estimates of the cost of CRC screening promotion and the added budget impact of screening with colonoscopy.

RESUMO

PURPOSE: The Texas Breast and Cervical Cancer Services (BCCS) program was established to address socioeconomic disparities in breast and cervical cancer screening and survival. This study examined the impact of the program on treatment and survival of breast cancer patients. METHODS: A retrospective analysis was performed using the Texas Cancer Registry data linked to the BCCS program data. The sample consisted of 40- to 64-year-old women screened and diagnosed with breast cancer through the BCCS program (participants) and similar women living in low socioeconomic status census tracts and diagnosed outside the program (comparison group) during 1995-2008. Regular screeners among the participants were also compared with the comparison group. RESULTS: Participants had lower rates of breast surgery and higher rates of chemotherapy as compared with the comparison group. Participants undergoing surgery had higher rates of mastectomy (as compared with breast-conserving surgery) and lower rates of adjuvant radiation therapy. Unadjusted survival rates were similar between the participants and the comparison group, and higher among regular screeners, which was primarily driven by stage at diagnosis. Adjusted survival rates were similar between the 3 groups. CONCLUSIONS: Although there are differences in the types of treatment provided to the participants and the comparison group, there is no evidence of guideline noncompliance or stage-inappropriate treatment provision in either of the groups. Despite being diagnosed with a more advanced stage, the participants had similar unadjusted and adjusted survival rates as the comparison group. Access to timely treatment improved survival and brought the underserved participants on par with the comparison group.

RESUMO

Continuous tobacco use in cancer patients is linked to substantial healthcare costs due to increased risks and complications, whereas quitting smoking leads to improved treatment outcomes and cost reductions. Addressing the need for empirical evidence on the economic impact of smoking cessation, this study examined the association between smoking cessation and healthcare cost utilization among a sample of 930 cancer patients treated at The University of Texas MD Anderson Cancer Center's Tobacco Research and Treatment Program (TRTP). Applying conditional quantile regression and propensity scores to address confounding, our findings revealed that abstinence achieved through the TRTP significantly reduced the median cost during a 3-month period post-quitting by $1,095 (ß=-$1,095, p=0.007, 95%CI=[-$1,886, -$304]). Sensitivity analysis corroborated these conclusions, showing a pronounced cost reduction when outlier data were excluded. The long-term accrued cost savings from smoking cessation could potentially offset the cost of participation in the TRTP program, underscoring its cost-effectiveness. An important implication of this study is that by reducing smoking rates, healthcare systems can more efficiently allocate resources, enhance patient health outcomes, and lessen the overall cancer burden.

RESUMO

Purpose: To evaluate the performance of a biopsy decision support algorithmic model, the intelligent-augmented breast cancer risk calculator (iBRISK), on a multicenter patient dataset. Materials and Methods: iBRISK was previously developed by applying deep learning to clinical risk factors and mammographic descriptors from 9700 patient records at the primary institution and validated using another 1078 patients. All patients were seen from March 2006 to December 2016. In this multicenter study, iBRISK was further assessed on an independent, retrospective dataset (January 2015-June 2019) from three major health care institutions in Texas, with Breast Imaging Reporting and Data System (BI-RADS) category 4 lesions. Data were dichotomized and trichotomized to measure precision in risk stratification and probability of malignancy (POM) estimation. iBRISK score was also evaluated as a continuous predictor of malignancy, and cost savings analysis was performed. Results: The iBRISK model's accuracy was 89.5%, area under the receiver operating characteristic curve (AUC) was 0.93 (95% CI: 0.92, 0.95), sensitivity was 100%, and specificity was 81%. A total of 4209 women (median age, 56 years [IQR, 45-65 years]) were included in the multicenter dataset. Only two of 1228 patients (0.16%) in the "low" POM group had malignant lesions, while in the "high" POM group, the malignancy rate was 85.9%. iBRISK score as a continuous predictor of malignancy yielded an AUC of 0.97 (95% CI: 0.97, 0.98). Estimated potential cost savings were more than $420 million. Conclusion: iBRISK demonstrated high sensitivity in the malignancy prediction of BI-RADS 4 lesions. iBRISK may safely obviate biopsies in up to 50% of patients in low or moderate POM groups and reduce biopsy-associated costs.Keywords: Mammography, Breast, Oncology, Biopsy/Needle Aspiration, Radiomics, Precision Mammography, AI-augmented Biopsy Decision Support Tool, Breast Cancer Risk Calculator, BI-RADS 4 Mammography Risk Stratification, Overbiopsy Reduction, Probability of Malignancy (POM) Assessment, Biopsy-based Positive Predictive Value (PPV3) Supplemental material is available for this article.

RESUMO

PURPOSE: To examine the geographic distribution of physician and pharmacist workforce specialized in oncology in the United States. METHODS: Using the National Provider Identifier data, we identified two types of oncology workforce via the healthcare provider taxonomy codes. Oncologists were physicians self-identified as providing oncologic care to patients. Oncology pharmacists were pharmacists with an oncology subspecialty. We calculated the geographic density of physician and pharmacist oncology workforce and used county-level cancer crude rates to quantify the demand for oncology workforce. We used spatial data to plot the density of oncology workforces relative to county-level cancer rates and compared the county-level density of oncologists and oncology pharmacists. RESULTS: Of the 30,553 members of the oncology workforce in 2019, 28,681 were oncologists and 1,090 were oncology pharmacists. The mean county-level density of oncologists was 2.94 (SD = 7.32) per 100,000 persons. Sixty-four percent of counties had no oncologists with primary practice location in that county and 12% had no oncologists in the local and adjacent counties. Counties in the top quartile of cancer rates had the highest percentage without any oncologists with primary practice location in the county (75%) and with no oncologists in the local as well as adjacent counties (16%). CONCLUSION: Geographically mismatched demand and supply characterized the current oncology workforce. Wide discrepancies in the supply of oncologists across geographic regions highlight the importance of developing core competencies for health professions not specialized in oncology to deliver quality cancer care in areas with unmet need for oncology care.

RESUMO

BACKGROUND: To date, the economic burden and patient-reported outcomes associated with carcinoid syndrome (CS) in patients with neuroendocrine tumor (NET) remain largely unknown. OBJECTIVES: The objective of this study was to perform a systematic review of economic and quality-of-life (QOL) studies related to the treatment of CS. METHODS: Articles included in the review were extracted from PubMed, Embase, and the Cochrane Library. Studies had to be in English and published between 1 January 2000 and 2 July 2020. Other study eligibility criteria included patients with NET with CS receiving treatment for CS, study outcomes of cost or QOL, and clinical trials or population-based studies using claims or other secondary databases. The interventions included somatostatin analogs, telotristat ethyl, or other treatment for CS. To evaluate the quality and bias of the included studies, the 24-item CHEERS and 10-item Gill and Feinstein checklists were used. We report a narrative synthesis of the findings from the selected studies. RESULTS: A total of 12 economic and 12 QOL studies met the inclusion criteria and were included for review. Patients with uncontrolled CS symptoms had 23-92% higher costs than those with controlled CS; mostly, ambulatory/outpatient services were the primary drivers of the costs. The use of telotristat ethyl may be cost effective if the societal willingness to pay is as high as $US150,000 per quality-adjusted life-year in the USA. Of the 12 QOL papers, only three case-control studies assessed QOL at baseline and more than two follow-up time points. Seven studies evaluated QOL at two or more time points but lacked a control group, obscuring direct intervention effects on patients' well-being. CONCLUSIONS: We observed wide variations in the reviewed studies evaluating the economic burden and patient-reported outcomes, in terms of cost and QOL, of patients with CS. Although QOL is consistently impaired and costs are consistently increased by CS, the numbers of both cost and QOL studies among this patient population remain sparse, and many of the existing studies indicated an important need for quality improvement.

RESUMO

BACKGROUND: The economic burden of renal cell carcinoma (RCC) had been reported to be significant in a previous review published in 2011. OBJECTIVE: The objective of this study was to perform an updated review by synthesizing economic studies related to the treatment of RCC that have been published since the previous review. METHODS: We performed a literature search in PubMed, EMBASE, and the Cochrane Library, covering English-language studies published between June 2010 and August 2018. We categorized these articles by type of analyses [cost-effectiveness analysis (CEA), cost analysis, and cost of illness (COI)] and treatment setting (cancer status and treatment), discussed findings from these articles, and synthesized information from each article in summary tables. RESULTS: We identified 52 studies from 2317 abstracts/titles deemed relevant from the initial search, including 21 CEA, 23 cost analysis, and 8 COI studies. For localized RCC, costs were found to be positively associated with the aggressiveness of the local treatment. For metastatic RCC (mRCC), pazopanib was reported to be cost effective in the first-line setting. We also found that the economic burden of RCC has increased over time. CONCLUSION: RCC continues to impose a substantial economic burden to the healthcare system. Despite the large number of treatment alternatives now available for advanced RCC, the cost effectiveness and budgetary impact of many new agents remain unknown and warrant greater attention in future research.

RESUMO

BACKGROUND: The influx of new oncologic technologies has changed the treatment landscape of renal cell carcincoma (RCC) in the last decade. This study updated a previously published paper on the economic burden of RCC in the USA by using more recent data to examine the impact of various forms of new oncologic technologies on the economic burden of RCC. METHODS: Using the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we employed prevalence and incidence costing approaches to estimate RCC costs from the payer's perspective. We conducted a longitudinal analysis of cost data per patient per month for a prevalence cohort of patients with RCC to determine which category of new technology (surgery, radiation, or cancer drugs) was the major cost driver for RCC. We then applied the incidence costing approach to estimate costs related to RCC by care phase (initial, continuing, and terminal) and compared costs between two incidence cohorts to examine how new technology affected the economic burden of RCC over time. RESULTS: After controlling for demographic factors, clinical characteristics, neighborhood socioeconomic status, and time trend, we found that rising per patient per month costs were driven by new technologies in cancer drugs. Incidence-based analysis showed the annual net cost (2018 US$) for patients with distant-stage RCC diagnosed between 2002 and 2006 was $51,639, $19,025, $76,603, and $29,045 for the initial, continuing (year 1), terminal (died from RCC), and terminal (died from other causes) care phases, respectively. Costs increased to $70,703, $34,716, $107,989, and $47,538, respectively, for the incidence cohort diagnosed between 2007 and 2011. CONCLUSION: The rising economic burden of RCC was most pronounced among patients with distant-stage RCC, and driven primarily by new cancer drugs.

RESUMO

INTRODUCTION: A previous study showed that use of positron emission tomography (PET)/computed tomography (CT) for surveillance after treatment of non-small-cell lung cancer (NSCLC) does not yield a detection or survival benefit over the use of chest CT. However, PET/CT remains a common method of follow-up imaging. Here we estimated and compared the costs of PET/CT versus CT for surveillance of patients with stage III NSCLC and identified patient and provider demographic characteristics associated with preference for use of PET/CT. PATIENTS AND METHODS: We reviewed 178 patients with stage III NSCLC who had received ≥ 1 PET/CT scan within 6 months of completing radiotherapy (n = 89) or had received CT after radiotherapy (n = 89) from 2000 to 2011. Costs were measured according to Medicare payments converted from institutional billing records. Total and imaging costs were analyzed at 6, 12, 18, and 24 months after the end of treatment. Patient and provider demographic characteristics were also evaluated for potential associations with PET/CT use. RESULTS: Total costs in the PET/CT group were higher during the first 18 months after treatment (P = .002 at 6 months, P = .019 at 12 months, and P = .018 at 18 months) but was marginally significant (P = .05) at 24 months. In univariate analysis of demographic variables, patients who lived in a state different from the treatment center might have been more likely to receive PET/CT (odds ratio [OR], 1.76; P = .051). In multivariate analysis, patients treated in 2007 to 2010 (OR, 29.9; P < .001) or 2003 to 2006 (OR, 11.6; P = .002) were more likely to receive PET/CT than patients treated in 1999 to 2002. In addition, radiation oncologists with > 10 years of experience were more likely to use PET/CT than those with less experience, although this result might be confounded by the small number of providers. CONCLUSION: Use of PET/CT was associated with higher costs for 18 months after treatment, but the difference was at the borderline of statistical significance at 24 months.

RESUMO

Pseudoprogression has been observed in patients with various tumor types treated with immunotherapy. However, the frequency of pseudoprogression is unknown in gastrointestinal malignancies. Metastatic colorectal cancer (mCRC) and advanced pancreatic ductal adenocarcinoma (PDAC) patients who progressed on treatment with immunotherapy beyond RECIST version 1.1 criteria were analyzed. Degree of progression, tumor markers, time to progression, overall survival, Eastern Cooperative Oncology Group Performance Status (ECOG PS), and costs were analyzed for patients treated beyond progression (TBP) and not treated beyond progression. Fifty-nine of 159 (37%) patients with mCRC or PDAC were TBP (31 mCRC, 28 PDAC). Fifty-four of 59 (92%) patients were microsatellite stable. Zero of these 59 patients with initial treatment beyond progression demonstrated subsequent radiographic tumor shrinkage at a median 42 days from first scan documenting progression. A pseudoprogression rate of >6% could be excluded with 95% confidence. Compared with baseline, median growth on the first and second scan that showed progression was 29.8% and 43%, respectively. In those not treated beyond progression, median growth at first restaging was 31.2%. The trend in change in tumor size positively correlated with the trend in tumor markers in all patients TBP. Fifteen patients (25%) experienced grade 3/4 adverse events by continuing treatment beyond progression, whereas 19 (32%) experienced deterioration in ECOG PS. Pseudoprogression was not seen in microsatellite stable patients with mCRC or PDAC treated with immunotherapy. Changes in tumor markers correlated with changes in tumor volume. This data may help inform future treatment decisions and/or trial design in patients with mCRC or advanced PDAC treated with immunotherapy.

RESUMO

BACKGROUND: The cornerstone of prostate cancer diagnosis remains the transrectal ultrasound-guided biopsy (TRUS-BX), which most frequently occurs in the office setting under local anesthesia. However, there are now other techniques of prostate biopsy aimed at improving outcomes such as patient comfort, significant cancer detection, and infectious complications. The purpose of the present study is to compare the cost and efficacy outcomes of five different approaches. METHODS: We compared the comprehensive costs of a random sample size of 20-30 cases from each of the following: (1) local anesthesia TRUS-BX (reference), (2) sedation TRUS-BX, (3) general anesthesia transperineal template biopsy (TP), (4) sedation MRI-TRUS fusion biopsy (FB), and (5) sedation in-bore MRI biopsy (IB-MRI). Cost categories included pre-procedure, anesthesia pharmacy and recovery, and the technical/professional costs from urology, radiology, and pathology services. For procedure outcomes, we compared the larger cohorts of TRUS-BX, TP, and FB in terms of indication, cancer yield, and downstream decision impact. RESULTS: Compared with standard TRUS-BX, the total costs of sedation TRUS-BX, TP, FB, and IB-MRI increased significantly ×1.9 (90%), ×2.5 (153%), ×2.5 (150%), and ×2.2 (125%), respectively (p < 0.001). Although there was no statistical difference between the total costs of TP, FB, and IB-MRI, these costs were significantly higher than those of TRUS-BX under either local anesthesia or sedation (p < 0.05). The cost of TRUS-BX under sedation was significantly higher than that of TRUS-BX under local anesthesia (p < 0.001). Compared to TRUS-BX, more significant cancers were detected in FB (16% vs. 36%) and TP (16% vs. 34%) groups (p < 0.001). CONCLUSIONS: Compared with standard TRUS-BX, the additions of imaging, sedation anesthesia, and transperineal template increase costs significantly, and can be considered along with known improvements in accuracy and side effects. Ongoing efforts to combine imaging and transperineal biopsy, especially in an outpatient/local anesthesia setting may lead to a higher cost/benefit.

RESUMO

BACKGROUND: There are few data to support the use of varying imaging modalities in evaluating recurrence in non-small-cell lung cancer (NSCLC). We compared the efficacy of surveillance positron emission tomography (PET)/computed tomography (CT) versus CT scans of the chest in detecting recurrences after definitive radiation for NSCLC. MATERIALS AND METHODS: We retrospectively analyzed 200 patients treated between 2000 and 2011 who met the inclusion criteria of stage III NSCLC, completion of definitive radiation treatment, and absence of recurrence within the initial 6 months. These patients were then grouped on the basis of the use of PET/CT imaging during postradiation surveillance. Patients who received ≥ 1 PET/CT scans within 6 months of the end of radiation treatment were placed in the PET group whereas all others were placed in the CT group. We compared survival times from the end of treatment to the date of death or last follow-up using log rank tests. Multivariate analysis was conducted to identify factors associated with decreased survival. RESULTS: In the entire cohort, median event-free survival (EFS) was 26.7 months, and median overall survival (OS) was 41.2 months. The CT group had a median EFS of 21.4 months versus 29.4 months for the PET group (P = .59). There was no difference in OS between the CT and PET groups (median OS of 41.2 and 41.3 months, respectively; P = .59). There was also no difference in local recurrence-free survival or distant metastases-free survival between the CT-only and PET/CT groups (P = .92 and P = .30, respectively). Similarly, in multivariate analysis, stratification into the PET group was not associated with improved EFS (hazard ratio [HR], 0.90; 95% confidence interval [CI], 0.61-1.34; P = .60) or OS (HR, 1.2; 95% CI, 0.83-1.7; P = .34). CONCLUSIONS: In stage III NSCLC patients treated with definitive radiation and without early recurrence, PET/CT scan surveillance did not result in decreased time to detection of locoregional or distant recurrence or improved survival.

RESUMO

The Texas Breast and Cervical Cancer Services (BCCS) program was established to address the socioeconomic disparities in stage at diagnosis and outcomes among breast cancer patients. This study examines the impact of Texas BCCS on stage at diagnosis among low socioeconomic status (SES) breast cancer patients. This is a retrospective analysis of women aged 40-64 years who were screened and diagnosed with breast cancer through the Texas BCCS program (participants) as compared with similar women living in low-SES census tracts and diagnosed outside the program (comparison group) during 1995-2008. Incident cases among the participants were compared with the comparison group as well. Stage at diagnosis was also analyzed separately for the years 1995-2002 and 2003-2008 in order to estimate the effect of BCCS-related Medicaid expansion in 2002. Over the study period of 1995-2008, BCCS participants had a 1.23 (P value<0.0001) times higher odds, and BCCS incident cases had 40% (P value<0.0001) lower odds of advanced stage at diagnosis as compared with the comparison group. A statistically significant difference in stage at diagnosis between the participants and the comparison group only existed for the 2003-2008 (post-Medicaid) period (odds ratio: 1.39, P value<0.0001). Texas BCCS program acts as a source of diagnosis and treatment access to many suspected cancer cases, especially since the 2002 Medicaid expansion, leading to more advanced stage at diagnosis among the BCCS cases as compared with other low-SES cases. Significant expansion of the program to serve a higher proportion of the eligible population is needed to achieve its goals as a screening program.
