To the best of our knowledge, this is the largest cohort used to compare RFA with SBRT in localized inoperable HCC, in that the largest previously published single-institution study included 224 patients, only 63 of whom were assigned to SBRT.22 The NCDB includes data from approximately 70% of all newly diagnosed patients with cancer in the United States, resulting in a high level of generalizability. Newest Articles <> We investigated how this missingness can bias results in breast cancer studies including patients treated with neoadjuvant chemotherapy (NAC). The data elements are collected prospectively from cancer registries of CoC-accredited programs by using nationally standardized data item and coding definitions as specified in the CoC’s facility oncology registry data standards and nationally standardized data transmission format specifications coordinated by the North American Association of Central Cancer Registries.16 The data elements include patient characteristics, cancer staging, tumor histologic characteristics, type and timing of first course of treatment, and outcomes information. Purpose Data that guide selection of optimal local ablative therapy for the management localized hepatocellular carcinoma (HCC) are lacking. A total of 47,634 patients with clinical stage I (T1N0M0) or stage II (T2N0M0) were identified from a population of 119,933 men and women diagnosed with primary HCC between 2004 and 2013 (International Classification of Disease-Oncology-3rd Edition code C22.0, histology codes 8170-8175). However, data abstraction rules from 2004 to 2007 resulted in missing clinical stage for a high percentage of cases. Please review the application instructions before you apply. NCDB data are used to analyze and track patients with malignant neoplastic diseases, their treatments and outcomes. Determine the Number of 2017 cases being submitted in the 2019 Call for Data. There are numerous publications regarding the use of SBRT for primary HCC.7,11,12,23,24 Some have focused on local tumor control rate as a primary end point, so long-term survival data are not reported.

Baseline patient characteristics are listed in Table 1. Overall Survival With RFA Versus SBRT in Patients With Nonsurgically Managed Stage I or II HCC. Characteristics and treatment … SBRT use was also more frequent in patients with tumor size ≥ 3cm and those with a low fibrosis score (0 to 4) or no fibrosis information recorded. For more information about ASCO's conflict of interest policy, please refer to www.asco.org/rwc or ascopubs.org/jco/site/ifc. It is possible that the inferior observed survival difference with SBRT was a result of subsequent lines of treatment. Finally, we attempted to control for an unmeasured confounder, specifically the presence of cirrhosis or advanced fibrosis, using sensitivity analyses. Survival curves stratified by year of diagnosis (2004-2008 v 2009-2013) are shown in Appendix Figure A2 (online only). However, underlying fibrosis data were not available for the majority of the patients (71.7%), so a sensitivity analysis of the potential effects of unmeasured severe fibrosis was performed. Search . This data item was added to the 2015 PUF (data released in Fall 2017), and does not appear in prior versions of the PUF data. The benefit of RFA was consistent across all subgroups examined and was robust to the effects of severe fibrosis/cirrhosis.

We attempted to address this by conducting a sensitivity analysis to assess the potential effect of underlying advanced fibrosis/cirrhosis. Institutions In our analysis, patients treated with RFA between 2009 and 2013 had significant improvement in OS compared with those treated between 2004 and 2008, although survival with SBRT remained unchanged over the years. ASCO Meetings 36, no. The data were accessed on a Participant User File (PUF) based award, and this study was approved by the Cleveland Clinic Institutional Review Board. All relationships are considered compensated. For example, assuming an HR of 2 for advanced fibrosis/cirrhosis, the prevalence of advanced fibrosis/cirrhosis in the SBRT group would need to be at least four times larger compared with that in the RFA group (relative risk of advanced fibrosis/cirrhosis, 4) to completely explain the observed survival detriment currently attributed to SBRT (a true HR of 1.0 for treatment with SBRT if the effect of severe fibrosis was removed). 2. Cancer. The primary objective of this study was to compare overall survival (OS) of nonsurgically managed patients with clinical stage I or II HCC treated with RFA with OS of those treated with SBRT. In addition, many of these single-institution studies are relatively small and lack long-term survival data.7,11,12. The Data Standards and Data Dictionary is intended for hospital and central cancer registries, programmers, and analysts, this provides detailed specifications and codes for each data item in the NAACCR data exchange record layout. 6. RFA is the most widely practiced intervention for small (< 3 cm) unresectable lesions, provides excellent local control rates reported at 70% to 90%, and is considered a curative treatment in some cases.7,8 Other interventional techniques, such as microwave ablation or combined thermal and transarterial chemoembolization have been used to improve these local control rates, particularly for HCC tumors between 3 cm and 5 cm.9,10 SBRT is an emerging alternative to RFA and seems to provide similar local control rates for small HCC.11 Although research on SBRT is increasing, most of the data on using SBRT come from single institutions, which are subject to selection bias. We demonstrated that our results were robust regarding the effect of this potential confounder.

Each record relates to one issuer’s provider network. Propensity Modeling of Receipt of SBRT. Moreover, many studies included patients who received SBRT as a bridge to transplantation rather than as a primary treatment modality, which results in an overestimation of the survival benefit from SBRT.23,24,26 In addition to efficacy, the cost of delivering treatment is important to consider when choosing among local ablative therapies. Figure 3. On the basis of the propensity score, a stabilized inverse probability of treatment weight was calculated.18 IPTWs were truncated at the 5th and 95th percentiles.

CancerLinQ Variable Attributes Some studies have reported that the local recurrence rate is higher with RFA compared with SBRT, especially in tumors > 3 cm.22,30 However, none of these studies have reported long- term survival outcomes, and few reports have examined the relationship between local control rate and eventual outcomes after SBRT.24,25 In our study, RFA was superior to SBRT, even if the tumor was > 3 cm. Our study suggests that treatment with RFA yields superior survival compared with SBRT for nonsurgically managed patients with stage I or II HCC. Candidate variables included all variables significantly associated with treatment modality via univariable analysis, with a threshold of P < .20 required for initial inclusion and P < .10 required to remain in the model. Advancement in navigation technology and multimodality image fusion represents an important development in interventional radiology.31-33 It has the potential to enhance the accuracy and effectiveness of RFA. We were unable to distinguish between patients with a solitary lesion with vascular invasion and multifocal tumors (all < 5 cm) in our analysis because the NCDB groups these together under T2 disease. JCO Clinical Cancer Informatics The NCDB, a joint program of the Commission on Cancer (CoC) of the American College of Surgeons and the American Cancer Society, is a registry containing data from more than 1,500 hospitals with CoC-accredited programs in the United States and includes approximately 70% of all newly diagnosed cases of cancer in the United States, consisting of more than 29 million unique cancer cases.14,15 According to the agreements executed with each accredited facility, data from the US Department of Veterans Affairs, Department of Defense, Puerto Rican facilities, and certain other programs are removed from research files. A full and detailed description of all the variables can be found in the NCDB PUF data dictionary. By using de-identified data exempt from oversight by the institutional review board, we performed a retrospective analysis using the NCDB. Fig 2. Treatment with SBRT requires complex treatment planning, quality assurance, and delivery procedures, which may lead to higher cost to the health care systems.27 Few studies have examined the cost-effectiveness of using SBRT to manage HCC.28,29 One such study showed that SBRT for initial treatment of localized inoperable HCC was not cost-effective compared with RFA.29.

Radiat Oncol 11:69, 2016. stream We focused on OS, but several other aspects of treatment selection such as toxicity, cost, location of tumor, and the patient’s ability to undergo invasive procedures such as RFA should be considered when dealing with unresectable localized HCC. This translated into a benefit of 10.4 months OS in favor of RFA. %PDF-1.7 To address these limitations, we performed propensity-matched analyses of a large NCDB sample that included 3,980 patients who did not receive surgery for stage I or II HCC and who were assigned to either RFA or SBRT. This data dictionary describes the variables contained in the Quality-PUF. Marketplaces, or were generated by CCIIO for use in data processing (i.e., system-generated). OS was measured from the date of diagnosis to the date of death as a result of any cause. Accessed January 2020. Patient-level variables included age at diagnosis, sex, race, insurance status, median household income according to patient ZIP code, percentage of persons with less than a high school education within the patient’s census tract of residence, and Charlson-Deyo comorbidity score (truncated by the NCDB into score categories of 0, 1, and ≥ 2).17 Facility-level variables included type of facility (as assigned by the CoC), distance from patient area of residence to treatment facility, case volume in quartiles, and geographic region. However, no data currently exist supporting the idea that these improvements in interventional radiology techniques have actually improved the outcomes of patients with HCC who were treated with RFA. Table 1. The CoC cannot be certain these findings represent the general U.S. population since their data reflect the makeup of CoC-accredited hospitals and their patients, but SEER data is collected by the National Cancer Institute and corroborates these NCDB findings. The Plan-PUF is available for … Each record relates to one issuer’s insurance plan. The combination of underlying patient characteristics (poor functional status, chronic liver disease) and the likelihood of disease progression in untreated liver cancer results in disappointing OS rates after SBRT of 21% to 69%.25 Methodologic concerns, such as relatively small sample size, selection bias, and intrinsic heterogeneity of the tumor have been advocated to explain this wide variation in survival. ASCO Author Services JCO Global Oncology Cancer. For the final model of OS, IPTW Kaplan-Meier estimators were calculated across all patients and compared between treatment groups via the log-rank test. Finally, cancer recurrence and cancer-specific survival data are not captured in the NCDB, which precludes assessment of these end points. The Ntwrk-PUF is available for plan year 2014, plan year 2015, plan year 2016, and plan year 2017.
