RESUMO
PURPOSE: In Israel, a public committee advises which new medications should be reimbursed subject to an annual budget allocation. The committee considers clinical trial outcomes, professional societies' preferences, projected budget impacts, and other social and ethical aspects. The Israeli oncologists' society places a strong emphasis on prioritizing adjuvant therapies because of their potential to advance cure. In 2023, several novel adjuvant therapies were suggested for national funding. Our objective was to ascertain whether Israeli decision makers have embraced the practice of prioritizing budgets for therapies with curative intent over late-disease therapy. METHODS: We collected data on all proposed cancer therapies for the 2023 update: indications, treatment settings, European Society for Medical Oncology-Magnitude of Clinical Benefit Scale (ESMO-MCBS) score, and whether accepted for reimbursement. The rates of acceptance were compared between drugs in curative and noncurative settings. Data were extracted from the official Israeli Ministry of Health publications and ESMO-MCBS website. RESULTS: Seven of the eight proposed therapies with curative intent received reimbursement approval (88%), in contrast to 11 of the 55 therapies for advanced/metastatic stages (20%). Among all advanced disease therapies with a high ESMO-MCBS score of 4, only four of 16 (25%) secured reimbursement approval. CONCLUSION: Our analysis revealed that during the 2023 reimbursement deliberations, Israeli policymakers embraced the prioritization of potentially curative therapies over treatments for incurable cancers, including several interventions that have demonstrated significant improvements in overall survival and/or quality of life. Introducing objective cost-effectiveness measures as a guiding framework for comparing competing medications may offer some resolution to this complex challenge.
RESUMO
The 21-gene Recurrence Score (RS) assay is a validated prognosticator/predictor of chemotherapy (CT) benefit in early-stage estrogen receptor (ER)-positive breast cancer (BC). Long-term data from real-life clinical practice where treatment was guided by the RS result are lacking. We performed exploratory analysis of the Clalit Health Services (CHS) registry, which included all CHS patients with node-negative ER+ HER2-negative BC who underwent RS testing between 1/2006 and 12/2009 to determine 10-year Kaplan-Meier estimates for distant recurrence/BC-specific mortality (BCSM) in this cohort. The analysis included 1365 patients. Distribution of RS results: RS 0-10, 17.8%; RS 11-25, 62.5%; RS 26-100, 19.7%. Corresponding CT use: 0, 9.4, and 69.9%. Ten-year distant recurrence rates in patients with RS 0-10, 11-25, and 26-100: 2.6% (95% confidence interval [CI], 1.1-6.2%), 6.1% (95% CI, 4.4-8.6%), and 13.1% (95% CI, 9.4-18.3%), respectively (P < 0.001); corresponding BCSM rates: 0.7% (95% CI 0.1-5.1%), 2.2% (95% CI, 1.3-3.7%), and 9.5% (95% CI, 6.0-14.9%) (P < 0.001). When the analysis included patients treated with endocrine therapy alone (95.5/87.5% of patients with RS 0-10/11-25), 10-year distant recurrence and BCSM rates for RS 0-10 patients were 2.7% (95% CI, 1.1-6.5%) and 0.8% (95% CI, 0.1-5.3%), respectively, and for RS 11-25 patients, 5.7% (95% CI, 3.9-8.3%) and 2.0% (95% CI, 1.1-3.7%), respectively. For RS 11-25 patients, no statistically significant differences were observed in 10-year distant recurrence/BCSM rates between CT-treated and untreated patients; however, this should be interpreted cautiously since the number of events was low and patients were not randomized. In conclusion, in node-negative ER+ HER2-negative BC patients, where treatment decisions in real-life clinical practice incorporated the RS, patients with RS 0-25 (~80% of patients, <10% CT use) had excellent outcomes at 10 years. Patients with RS 26-100 had high distant recurrence risk despite CT use and are candidates for new treatment approaches.
RESUMO
BACKGROUND: Anatomic location of primary tumors across the colon correlate with survival in the metastatic setting, whereas left-sided tumors may exhibit superior survival compared with right-sided tumors. The Oncotype Recurrence Score (RS) assay is a clinically validated predictor of recurrence risk in patients with stage II colorectal cancer (CRC). Previous studies had indicated that without adjuvant chemotherapy, CDX2-negative stage II CRC tumors are associated with a lower rate of disease-free survival than CDX2-positive stage II CRC tumors. We aimed to evaluate whether these two validated prognostic biomarkers may correlate with primary tumor location, and whether tumor location may reflect differential prognosis in stage II CRC. MATERIALS AND METHODS: We retrospectively analyzed patients with T3 mismatch repair-proficient (MMR-P) stage II CRC for whom RS assay was performed. Pathological report was reviewed for exact primary tumor location and CDX2 immunostaining. RS and CDX2 expression were correlated with primary tumor location. RESULTS: The analysis included 1,147 patients with MMR-P stage II CRC (median age 69 years [range 29-93]). Tumor distribution across the colon was as follows: 46% (n = 551) were right-sided and 54% (n = 596) were left-sided. RS was higher in right-sided tumors (p = .01). The RS results gradually decreased across the colon (cecum, highest score; sigmoid, lowest score; p = .04). Right-sided tumors exhibited more CDX2-negative tumors (p = .07). CONCLUSION: Our study indicates that right-sided colorectal tumors may display worse prognosis compared with left-sided tumors in MMR-P stage II CRC. Primary tumor location may serve as a prognostic factor that should be taken into account for recurrence risk assessment and consideration of adjuvant treatment. IMPLICATIONS FOR PRACTICE: Sidedness matters, even in stage II colorectal cancer (CRC). Using two previously established prognostic tools, the Oncotype DX assay and CDX2 expression, this study found that right-sided tumors may display worse prognosis compared with left-sided tumors in mismatch repair-proficient stage II CRC. Therefore, primary tumor location should be taken into account for recurrence risk assessment and consideration of adjuvant treatment.

The Recurrence Score® is increasingly used in node-positive ER+ HER2-negative breast cancer. This retrospective analysis of a prospectively designed registry evaluated treatments/outcomes in node-positive breast cancer patients who were Recurrence Score-tested through Clalit Health Services from 1/2006 through 12/2011 (N = 709). Medical records were reviewed to verify treatments/recurrences/survival. Median follow-up, 5.9 years; median age, 62 years; 53.9% grade 2; 69.8% tumors ≤ 2 cm; 84.5% invasive ductal carcinoma; 42.0% N1mi, and 37.2%/15.5%/5.2% with 1/2/3 positive nodes; 53.4% Recurrence Score < 18, 36.4% Recurrence Score 18-30, and 10.2% Recurrence Score ≥ 31. Overall, 26.9% received adjuvant chemotherapy: 7.1%, 39.5%, and 86.1% in the Recurrence Score < 18, 18-30, and ≥ 31 group, respectively. The 5-year Kaplan-Meier estimates for distant recurrence were 3.2%, 6.3%, and 16.9% for these respective groups and the corresponding 5-year breast cancer death estimates were 0.5%, 3.4%, and 5.7%. In Recurrence Score < 18 patients, 5-year distant-recurrence rates for N1mi/1 positive node/2-3 positive nodes were 1.2%/4.4%/5.4%. As patients were not randomized to treatment and treatment decision is heavily influenced by Recurrence Score, analysis of 5-year distant recurrence by chemotherapy use was exploratory and should be interpreted cautiously: In Recurrence Score < 18, recurrence rate was 7.7% in chemotherapy-treated (n = 27) and 2.9% in chemotherapy-untreated patients (n = 352); P = 0.245. In Recurrence Score 18-30, recurrence rate in chemotherapy-treated patients (n = 102) was significantly lower than in untreated patients (n = 156) (1.0% vs. 9.7% P = 0.019); in Recurrence Score ≤ 25 (the RxPONDER study cutoff), recurrence rate was 2.3% in chemotherapy-treated (n = 89) and 4.4% in chemotherapy-untreated patients (n = 488); P = 0.521. In conclusion, our findings support using endocrine therapy alone in ER+ HER2-negative breast cancer patients with micrometastases/1-3 positive nodes and Recurrence Score < 18.
RESUMO
The 21-gene Recurrence Score® (RS) assay is a validated prognostic/predictive tool in ER + early-stage breast cancer. However, clinical outcome data from prospective studies in RS ≥ 11 patients are lacking, as are relevant real-life clinical practice data. In this retrospective analysis of a prospectively designed registry, we evaluated treatments/clinical outcomes in patients undergoing RS-testing through Clalit Health Services. The analysis included N0 ER + HER2-negative breast cancer patients who were RS-tested from 1/2006 through 12/2010. Medical records were reviewed to verify treatments/recurrences/survival. The cohort included 1801 patients (median follow-up, 6.2 years). Median age was 60 years, 50.4% were grade 2 and 81.1% had invasive ductal carcinoma; 48.9% had RS < 18, 40.7% RS 18-30, and 10.4% RS ≥ 31, with chemotherapy use of 1.4, 23.7, and 87.2%, respectively. The 5-year Kaplan-Meier estimates for distant recurrence were 0.8, 3.0, and 8.6%, for patients with RS < 18, RS 18-30 and RS ≥ 31, respectively; the corresponding 5-year Kaplan-Meier estimates for breast cancer death were 0.0, 0.9, and 6.2%. Chemotherapy-untreated patients with RS < 11 (n = 304) and 11-25 (n = 1037) (TAILORx categorization) had 5-year Kaplan-Meier estimates for distant recurrence risk/breast cancer death of 1.0%/0.0% and 1.3%/0.4%, respectively. Our results extend those of the prospective TAILORx trial: the 5-year Kaplan-Meier estimates for distant recurrence and breast cancer death rate for the RS < 18 patients were very low supporting the use of endocrine therapy alone. Furthermore, in chemotherapy-untreated patients with RS 11-25 (where TAILORx patients were randomized to chemoendocrine or endocrine therapy alone), 5-year distant recurrence rates were also very low, suggesting that chemotherapy would not have conferred clinically meaningful benefit.
RESUMO
OBJECTIVES: To evaluate the impact of the 12-gene Colon Cancer Recurrence Score Assay-a clinically validated prognosticator in stage II colon cancer after surgical resection-on adjuvant treatment decisions in T3 mismatch repair proficient (MMR-P) stage II colon cancer in clinical practice. METHODS: This retrospective analysis included all patients with T3 MMR-P stage II colon cancer (Clalit Health Services members) with Recurrence Score results (time frame January 2011 to May 2012). Treatment recommendations pretesting were compared with the treatments received. Changes were categorized as decreased (to observation alone/removing oxaliplatin from the therapy) or increased (from observation alone/adding oxaliplatin to the therapy) intensity. RESULTS: The analysis included 269 patients; 58%, 32%, and 10% of the values were in the low (<30), intermediate (30-40), and high (≥41) score groups, respectively. In 102 patients (38%), treatment changed post-testing (decreased/increased intensity 76/26 patients). The overall impact was decreased chemotherapy use (45.0% to 27.9%; P < 0.001). Treatment changes occurred in all score groups, but more frequently in the high (change rate 63.0%; 95% confidence interval [CI] 42.3%-80.6%) than in the intermediate (30.6%; 95% CI 21.0%-41.5%) and low (37.6%; 95% CI 30.0%-45.7%) score groups. The direction of the change was consistent with the assay result, with increased intensity more common in higher score values and decreased intensity more common in lower score values. CONCLUSIONS: Testing significantly affected adjuvant treatment in T3 MMR-P stage II colon cancer in clinical practice. The study is limited by its design, which compared treatment recommendations pretesting to actual treatments received post-testing, lack of a control group, and nonassessment of confounding factors that may have affected treatment decisions.

OBJECTIVE: To study the implications of implementing the International Association of Diabetes in Pregnancy Study Group (IADPSG) recommendations for screening and diagnosis of gestational diabetes mellitus (GDM) in Israel and explore alternative methods for identifying women at risk for adverse pregnancy outcomes. RESEARCH DESIGN AND METHODS: We analyzed data of the Israeli Hyperglycemia and Adverse Pregnancy Outcomes study participants (N = 3,345). Adverse outcome rates were calculated and compared for women who were positive according to 1) IADPSG criteria, 2) IADPSG criteria with risk stratification, or 3) screening with BMI or fasting plasma glucose (FPG). RESULTS: Adopting IADPSG recommendations would increase GDM diagnosis by â¼50%. One-third of IADPSG-positive women were at low risk for adverse outcomes and could be managed less intensively. FPG ≥89 mg/dL or BMI ≥33.5 kg/m(2) at 28-32 weeks of gestation detected proportions of adverse outcomes similar to IADPSG criteria. CONCLUSIONS: Implementing IADPSG recommendations will substantially increase GDM diagnosis. Risk stratification in IADPSG-positive women may reduce over-treatment. Screening with FPG or BMI may be a practical alternative.

BACKGROUND: Activating mutations of the oncogene K-RAS are a common finding within cells of malignant, sporadic colorectal cancer. The existence of such mutations endows the tumor with proliferation potential which is independent of external stimuli by growth factors such as the epidermal growth factor of upstream receptor (EGFR]. Hence, anticancer, novel biologic drugs, aimed at inhibiting the EGFR, such as cetuximab, are rendered ineffective in cases of colorectal cancer harboring activated K-RAS. AIMS: Quantification and characterization of activating mutations in a large cohort of sporadic colorectal tumors in the Israeli population. METHODS: The results of a mutation analysis kit application in 419 tumor samples collected in Israel during the years 2007-2009 by the diagnostic unit of Teva in Israel--Oncotest-Advantest Ltd. RESULTS: The utilization of a direct, pre-specified mutation kit analysis (TheraScreen: K-ras Mutation Kit) has identified a total rate of 44.8% mutations. Most mutations (82.4%) were identified within codon 12 and the minority on codon 13. These results are in concordance with modern series conducted worldwide.

OBJECTIVE: Oncotype DX, a 21-gene assay, was clinically validated as a predictor of 10-year recurrence-free survival and treatment response in patients with early-stage estrogen-receptor-positive, lymph-node negative breast cancer (ER+ LN- ESBC). This study determined "real-life" alteration in treatment decision and economic implications of Oncotype DX use in women with ER+ LN- ESBC. METHODS: Clalit Health Services (CHS, Tel Aviv, Israel), determined the proportion of women in low, intermediate and high-risk groups in the first 368 Oncotype DX assays performed, the change of adjuvant therapy recommendation following the recurrence (RS) results from Oncotype DX use, and associated chemotherapy costs. The risk of recurrence-free survival was derived from prespecified statistical protocols of NCI-sponsored trials conducted by NSABP (B-14 and B-20). Utilities were literature based. A 3% discount rate was employed. RESULTS: Oncotype DX altered recommendations of 40% of patients, 84% of whom were changed from hormone + chemotherapy to hormonal therapy alone. Among high-risk women, 8% switched actual treatment from hormonal therapy to hormone + chemotherapy. By reducing the chemotherapy disutility, quality-adjusted life-years (QALY) increased 0.170 years. Use of Oncotype DX costs $10,770 per QALY gained. Sensitivity analyses revealed that risk reduction in the low-risk population, the cost of adverse events, and the relative risk reduction of recurrence were the most influential variables. CONCLUSION: Oncotype DX resulted in net QALY gain and increased overall costs, with an incremental cost-effectiveness ratio of $10,770. For CHS, Oncotype DX represents an effective and affordable approach to favorably affect the lives of women with ESBC.
