This study estimated the difference in overall survival for the standard of care (\"Neoadjuvant First\") vs upfront surgery first followed by adjuvant chemotherapy (\"Surgery First\").PATIENTS AND METHODSUsing Surveillance, Epidemiology, and End Results data, we identified patients age 5-29, diagnosed with a primary cancer of upper or lower extremity osteosarcoma between 2007 and 2019 who received surgery and chemotherapy. Our primary endpoint was the 5-year survival difference between the Surgery First and Neoadjuvant First groups.RESULTSAdjusted 5-year survival was 74% for Surgery First patients and 67% for Neoadjuvant First patients, with a survival difference of 6.9% (95% CI -4.2% - 16.1%). In sensitivity analyses of 5-year survival, the results were consistent, showing a 6.8% to 13.7% higher 5-year survival in Surgery First patients. Significant mortality risk factors included older age, larger tumor size, the type of resection (salvage vs amputation), and stage 3-4 disease (vs stage 1-2 disease).CONCLUSIONThe evidence supporting neoadjuvant therapy in osteosarcoma care is weak. However, there is evidence that pausing chemotherapy in the peri-surgical period might affect outcomes. Consequently, this study, and its consistency with the results from the only randomized trial, suggests that there is reason to revisit a prospective, randomized trial of osteosarcoma treatment regarding the timing of surgery and chemotherapy.","PeriodicalId":501635,"journal":{"name":"Journal of the National Cancer Institute","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142273389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the rigor of the peer-reviewed literature cited in the National Coverage Determination Memorandum for the FoundationOne CDx (F1CDx). Methods We identified studies cited in the memorandum. Two independent researchers evaluated each study and applied a modified version of the Fryback and Thornbury hierarchy[1], an established framework for evaluating the efficacy of diagnostic tests. Studies focused on clinical outcomes were then categorized by study design, guided by recommendations from the Center for Medical Technology Policy. Results The sample included 113 scientific studies. The majority (n = 60, 53.1%) used CGP outside the course of clinical care, and there was significant heterogeneity in the cancer types assessed and sequencing depth. We found 8 (7.1%) studies that assessed whether clinical care had changed due to CGP testing, and 38 (33.6%) assessed clinical outcomes. After excluding studies that tested for five or fewer genomic alterations, 25 remained in the clinical outcomes sample: Of these, only one included a comparator group that did not receive CGP testing. Only four studies used F1CDx as the primary genomic test, none of which compared the outcomes of patients who did vs did not receive the F1CDx test. Conclusions The findings indicate gaps in the supporting evidence for broad CGP use in patients with solid tumors. More rigorous studies that assess clinical utility would better inform the approval process for novel diagnostic tests.","PeriodicalId":501635,"journal":{"name":"Journal of the National Cancer Institute","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the value of a mailed outreach strategy for HCC screening in patients with cirrhosis. Methods We conducted a multi-center pragmatic randomized clinical trial comparing mailed outreach for HCC screening (n = 1436) and usual care with visit-based screening (n = 1436) among patients with cirrhosis at three health systems from March 2018 to September 2021. Outcomes of interest were early-stage HCC detection (ie, screening benefit) and diagnostic evaluation for false positive or indeterminate results (ie, screening harm). Screening harm was categorized as mild, moderate, and severe based on number and type of diagnostic exams. All patients were included in intention-to-screen analyses. Results Of 125 patients diagnosed with HCC (67 outreach and 58 usual care), 71.2% were found at an early stage per the Milan Criteria. Early tumor detection did not significantly differ between the outreach and usual care arms (64.2% vs 79.3%, p = .06). The proportion of patients with physical harms also did not differ between the outreach and usual care arms (10.8% vs 10.7%, p = .95) with 5.9% in both arms having mild harms, 4.0% and 3.8% respectively with moderate harms, and 0.9% and 1.0% respectively with severe harms.

This study compares the clinical outcome and response to chemotherapy between patients with resectable muc-GC, intestinal (int-GC) and diffuse (dif-GC) gastric cancer. Methods Patients from the D1/D2 study or the CRITICS trial were included in exploratory surgery-alone (SAtest) or chemotherapy test (CTtest) cohorts. Real-world data from the Netherlands Cancer Registry on patients treated between with surgery-alone (SAvalidation), and receiving preoperative chemotherapy with or without postoperative treatment (CTvalidation) were used for validation. Histopathological subtypes were extracted from pathology reports filed in the Dutch Pathology Registry and correlated with tumor regression grade (TRG) and relative survival (RS). Results In SAtest (n = 549) and SAvalidation (n = 8062) cohorts, muc-GC patients had a five-year RS of 39% and 31%, similar to or slightly better than dif-GC (43% and 29%, p = .52 and p = .011), but worse than int-GC (55% and 42%, p = .11 and p < .001). In CTtest (n = 651) and CTvalidation (n = 2889) cohorts, muc-GC showed favorable TRG (38% and 44% (near-)complete response) compared to int-GC (26% and 35%) and dif-GC (10% and 28%, p < .001 and p = .005).

However, the associations between AL, colorectal cancer (CRC) risk and all-cause mortality in patients with CRC remain unclear. Methods We analyzed the association between AL and CRC risk in 304,959 adults and all-cause mortality in 1,794 patients with CRC from the UK Biobank, using Cox proportional hazards regression models. Results Compared to the AL level in the first quartile, individuals in the second to fourth quartiles had a respective 20%, 29%, and 43% increased risk of CRC; 15%, 24%, and 42% increased risk for colon cancer; and 30%, 38%, and 45% increased risk for rectal cancer. We identified a positive dose-gradient association of AL score with CRC risk, including colon and rectal cancer. Additionally, the association between AL and increased risk of CRC was observed across different strata of genetic susceptibility for CRC. Eliminating AL exposures could prevent nearly 39.24% (95% CI: 36.16-42.32) of CRC incident cases. Meanwhile, a significant association between the AL and all-cause mortality in patients with CRC was found, with a HR of 1.71 (95% CI: 1.16-2.50) for the fourth quartile compared to the AL score in the first quartile, demonstrating a positive dose-response relationship.

We examine assumptions and potential power gains from exploiting information from testing control-arm specimens, which we call the “intended effect” (IE) analysis that we explain in detail herein. The IE analysis is particularly suited to tests that can be conducted on stored specimens in the control arm, such as stored blood for multicancer detection (MCD) tests. Methods We simulated hypothetical MCD screening trials to compare power and sample size for the standard vs IE analysis. Under two assumptions that we detail herein, we projected the IE analysis for 3 existing screening trials (National Lung Screening Trial [NLST], Minnesota Colon Cancer Control Study [MINN-FOBT-A], and Prostate, Lung, Colorectal, Ovarian Cancer Screening Trial—colorectal component [PLCO-CRC]). Results Compared with the standard analysis for the 3 existing trials, the IE design could have reduced cancer-specific mortality P values 6-fold (NLST), 33-fold (MINN-FOBT-A), or 260 000-fold (PLCO-CRC) or, alternately, reduced sample size (90% power) by 25% (NLST), 47% (MINN-FOBT-A), or 63% (PLCO-CRC). For potential MCD trial designs requiring 100 000 subjects per arm to achieve 90% power for multicancer mortality for the standard analysis, the IE analysis achieves 90% power for only 37 500-50 000 per arm, depending on assumptions concerning control-arm test-positives. Conclusions Testing stored specimens in the control arm of screening trials to conduct the IE analysis could substantially increase power to reduce sample size or accelerate trials and could provide particularly strong power gains for MCD tests.","PeriodicalId":501635,"journal":{"name":"Journal of the National Cancer Institute","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142231333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examine the association of Medicaid enrollment timing and patterns with survival among children and adolescents/young adults (AYAs) diagnosed with blood cancers, where disease onset can be acute and early detection is critical. Methods We identified 28,750 children and AYAs (0-39 years) newly diagnosed with blood cancers from the 2006-2013 SEER-Medicaid data. Enrollment patterns included continuous Medicaid (preceding through diagnosis), newly gained Medicaid (at/shortly after diagnosis), other noncontinuous Medicaid enrollment, and private/other insurance. We assessed cumulative incidence of death from diagnosis, censoring at last follow-up, five years post-diagnosis, or December 2018, whichever occurred first. Multivariable survival models estimated the association of insurance enrollment patterns with risk of death. Results One-fourth (26.1%) of the cohort were insured by Medicaid; of these, 41.1% had continuous Medicaid, 34.9% had newly gained Medicaid, and 24.0% had other noncontinuous enrollment. The cumulative incidence of all-cause death five-year post-diagnosis was highest in patients with newly gained Medicaid (30.2%, 95%CI = 28.4-31.9%), followed by other noncontinuous enrollment (23.2%, 95%CI = 21.3-25.2%), continuous Medicaid (20.5%, 95%CI = 19.1-21.9%), and private/other insurance (11.2%; 95%CI = 10.7-11.7%).

The primary outcome was receipt of a molecular diagnostic test, based on claims data. The primary predictors were race and SES. Likelihood of receiving a molecular diagnostic test, and overall survival (OS), were investigated using logistic and Cox proportional hazards regression, adjusted for sex, age, residence, histology, marital status, and comorbidity.RESULTSOf the 28,511 NSCLC patients, 11,209 (39.3%) received molecular diagnostic testing.
