Clinical Outcomes of Patients with HER2 Positive Metastatic Breast Cancer to the Brain, with First-Line Trastuzumab, Pertuzumab and Chemotherapy, in a Real-World Setting.

Background: In this observational study, we analyzed the treatment patterns and clinical outcomes of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (mBC) who developed brain metastases during their disease in a 2.7 million-member public health-provider in Israel. Methods: Newly diagnosed patients with mBC who initiated first-line treatment between January 2013 and June 2021 were identified. Time on treatment (ToT) and overall survival (OS) were assessed at a minimum of 6 months follow-up (cutoff: December 2021). Results: We identified a total of 61 patients: 98.4% females, median age 50 years (IQR = 44-63), 85% invasive ductal tumors, 44% hormone receptor positive, 51% performance status 0-1. The median duration of follow-up was 6.2 years. All patients initiated a combination treatment of trastuzumab, pertuzumab, and chemotherapy (TPC), and 72% moved to second-line treatment during the study follow-up period (82% ado-trastuzumab emtansine). The median ToT for first-line and second-line treatments were 16.9 months (95% CI = 13.9-27.7) and 7.9 months (95% CI = 5.6-10.9), respectively. The median overall survival (OS) was 45.5 months (95% CI = 35.4-71.2) from the initiation of first-line treatment. When considering the timing of brain metastases, the median OS was 36.3 months (95% CI = 10.0-NR) for those diagnosed upfront (n = 15, 25%), 59.1 months (95% CI = 32.5-NR) for those diagnosed while on TPC (n = 25, 41%), and 40.8 months (95% CI = 35.4-NR) for those diagnosed at a later stage (n = 21, 34%). The median OS from brain metastases diagnosis was 25.1 months (95% CI = 17.0-34.6). Conclusion: Patients with upfront brain involvement at the time of mBC diagnosis had shorter survival compared to those who started TPC without brain metastases. Nonetheless, the overall results from this study compare favorably with previous studies and contribute to understanding the value of traditional treatment options, which will serve as a baseline for future treatment strategies in the real-world setting.

Time on Treatment and Survival Outcomes for Patients Treated With First-line Osimertinib vs. Other Tyrosine Kinase Inhibitors, for EGFR Mutation-positive Metastatic Non-small Cell Lung Cancer: Real-world Experience Data.

BACKGROUND/AIM: In this observational study, we analyzed the time on treatment (ToT) and overall survival (OS) of patients with metastatic non-small cell lung cancer (mNSCLC) in a 2.7-million-member public health provider in Israel. PATIENTS AND METHODS: Newly diagnosed patients with mNSCLC who initiated first-line tyrosine kinase inhibitor (TKI) therapy between Jan 2017-Dec 2020 were identified from the National Cancer Registry and Maccabi Healthcare Services database. Outcomes were assessed at a minimum of 23 months of follow-up (cutoff: 30th November 2022). All analyses compared first-line treatment osimertinib vs. standard TKIs (erlotinib, afatanib or gefitinib). RESULTS: A total of 165 patients (59% female, median age 68 years) were identified, including 58% smokers, 95% with adenocarcinomas, 33% with brain metastases, and 62%/15%/23% with 0-1/2-4/unknown performance status (PS). Of these, 77 (47%) were treated with standard TKI drugs and 88 (53%) with osimertinib as first-line treatment. The median duration of follow-up was 33.6 months (95%CI=29.9-37.3) and 58.5 months (95%CI=52.5-64.4) for patients who received osimertinib and standard TKIs, respectively. The median ToT (in months) was significantly (p<0.0001) longer with osimertinib (17.6; 95%CI=13.71-23.9) vs. standard TKIs (9.40; 95%CI=7.17-12.1). The 24-month survival rate was 58.0% among patients who received osimertinib and 50.6% among those who received standard TKI therapy (p=0.18). From second-line treatment initiation, 43.8% of those who received second-line osimertinib and 17.7% of those that received other second-line treatment were still alive at 24 months. CONCLUSION: Compared to standard TKIs, first-line osimertinib treatment was associated with a significantly longer ToT, and a longer OS. Our cohort also included patients with PS 2-4 who would not necessarily be included in clinical trials, allowing analysis of a real-world population.

Publicly Funded Cancer Care: Are Adjuvant Therapies Prioritized Over Treatment of Metastatic Cancer? The Israeli Experience.

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.

Real-world outcomes of patients with metastatic endocrine-responsive breast cancer receiving palbociclib-based combinations.

Aim: To describe treatment journey and clinical outcomes after palbociclib initiation in HR+/HER2- breast cancer patients across multiple lines. Materials & methods: Adult patients (n = 559) were identified in a population-based study between January 2018 and June 2020. Results: Median follow-up time was 41.2 months. The starting dose was 125 mg for more than 85% of patients, and a third had dose reduction. Median time on treatment was 30.5 months for palbociclib + aromatase inhibitors for patients that received first-line treatment after metastatic diagnosis, and 12.6 months for palbociclib + fulvestrant across multiple lines, and longer for patients that had a dose reduction during treatment. At 48 months, 59.3 and 27.3% of patients were still alive, respectively. Subsequent lines resulted in median time on treatment of 4.4-7.7 months in both groups. Conclusion: Time on treatment for palbociclib was comparable to data from clinical trials, and follow-up allowed us to examine subsequent treatment after initial treatment failure. Dose reduction was common in the real-world setting and did not adversely affect efficacy.

We used healthcare data from Israel to study the outcomes of adults (mostly women) who had breast cancer that spread (metastatic) and who started treatment with anticancer medications in the form of palbociclib in combination with either aromatase inhibitors (as first treatment after metastatic disease diagnosis) or fulvestrant (after having been treated with a different medication) between January 2018 and June 2020. Patients treated with palbociclib with aromatase inhibitors (52%) were on average 63 years old, and most had medium to high socioeconomic status (63%) and functioned independently (60%). Patients were treated on average for 30.5 months, and just over a third switched to a different treatment after their disease worsened. Four years after starting treatment, 59% of patients were still alive. Patients treated with palbociclib and fulvestrant, after having been treated with a different medication (48%), were on average 66 years old, and 61% had medium to high socioeconomic status and 50% functioned independently. These patients were treated on average for 12.6 months, and over two-thirds switched to a new treatment. Four years after starting this treatment, 27% of patients were still alive. Overall, most patients included in this study started treatment with the recommended dose of palbociclib (125 mg), and a third had to change to a lower dose to continue treatment (probably due to side effects). Clinical trial registration: NCT04671615 (ClinicalTrials.gov).

Association between diabetes mellitus and reduced efficacy of pembrolizumab in non-small cell lung cancer.

BACKGROUND: Diabetes mellitus (DM) is a highly prevalent chronic metabolic disorder. Although DM has been associated with immune dysfunction, the effect of DM on the efficacy of immunotherapy is unknown. This study aimed to evaluate the impact of DM on the efficacy of pembrolizumab in metastatic non-small cell lung cancer (NSCLC). METHODS: The authors reviewed the medical records of consecutive metastatic NSCLC patients treated with first-line pembrolizumab either alone or in combination with chemotherapy at a single tertiary center. For validation, a computerized data from Maccabi Healthcare Services, a 2.5-million-member state health service was used. RESULTS: Of the 203 eligible patients, 51 (25%) had DM. Patients with DM had a significantly shorter median progression-free survival (PFS) (5.9 vs. 7.1 months, p = .004) and overall survival (OS) (12 vs. 21 months, p = .006). The shorter OS in diabetic patients was more pronounced when pembrolizumab was given alone (12 vs. 27 months, p = .03) than when combined with chemotherapy (14.3 vs. 19.4 months, p = .06). Multivariate analysis confirmed DM as an independent risk factor for shorter PFS (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.11-2.50, p = .01) and OS (HR, 1.73; 95% CI, 1.09-2.76, p = .02). In a validation cohort of 452 metastatic NSCLC patients, the time on pembrolizumab treatment was shorter in diabetic patients (p = .025), with only 19.6% of patients remaining on treatment at 12 months compared to 31.7% of the nondiabetic patients. CONCLUSIONS: This study suggests immunotherapy is less beneficial in diabetic NSCLC patients. More work is needed to verify our findings and explore similar effects in other cancer entities.

The reimbursement process in three national healthcare systems: variation in time to reimbursement of pembrolizumab for metastatic non-small cell lung cancer.

In this article, we focus on the reimbursement process, and as an example, characterize the time to reimbursement of pembrolizumab, a PD-1 immune checkpoint inhibitor for treatment of metastatic NSCLC from publicly available websites, in three different healthcare systems: The National Institute for Health and Care Excellence (NICE) in the UK, the Pharmaceutical Benefits Advisory Committee (PBAC) in Australia, and the National Advisory Committee for the Basket of Health Services in Israel, all who have publicly funded health systems which include drug coverage. Our study found that there are substantial differences in time to reimbursement of pembrolizumab for the same conditions in different countries, with NICE and The National Advisory Committee for the Basket of Health Services in Israel approving one condition at the same time, Israel approving two conditions earlier than NICE, and PBAC lagging behind for every condition. These differences could be due to the differences in health policy systems and the many factors that affect reimbursement. Comparing the reimbursement process between different countries can highlight the challenges facing their health systems in early adoption of new treatments.

Predictors of treatment initiation and mapping the cancer diagnostic pathway: A retrospective observational cohort study of patients with metastatic non-small cell lung cancer.

BACKGROUND: Health-care providers in the US revealed that a substantial proportion of mNSCLC patients do not receive any first-line therapy and the biggest gaps in care are time inefficiencies in the diagnostic process. The goal of this study was to determine whether such gaps are found in Israel where healthcare is universal and participation in a medical insurance plan is free and compulsory. METHODS: We conducted a retrospective, observational cohort study using the computerized data of Maccabi Healthcare Services, a 2.5 million-member state-mandated health-service. Patients with mNSCLC diagnosed between 2017 and 2018 were followed until December 2019. RESULTS: Among 434 patients (62% male, mean age 68 y, 74% adenocarcinoma), 345 (79%) initiated first-line treatment. Compared to treated, untreated patients (n = 89) were more likely to be older (mean [SD]=71 years [10] vs. 67 [10], p < 0.001), have a higher co-morbidity index (5.6 ([4.4] vs. 4.0 [3.4], p < 0.001), smokers (84% vs. 66%, p = 0.001), and require hospitalization in the year prior to diagnosis (80% vs 61%, p = 0.002). There was no difference in socioeconomic status. Time from first symptom to imaging was longer for untreated than treated patients (6.51 months [4.24, 7.33] vs 3.48 months [2.76, 4.34] respectively, p = 0.22). Predictors of treatment initiation included age< 70 years, non-smokers, EGFR testing performed, ECOG performance status 0-1 and shorter wait from first symptom to imaging. Median time from first symptom to initiation of 1 L, was 7.76 months (6.51-8.75). CONCLUSION: The proportion of untreated mNSCLC patients are comparable to those reported in the US; we did not find health disparities between socioeconomic levels. Our data suggest that the main barrier to effective diagnostic process is the wait between symptom complaint and imaging.

[PERSONALIZED MEDICINE IN ONCOLOGY REQUIRES TEAMWORK BETWEEN MEDICAL ONCOLOGISTS AND MOLECULAR PATHOLOGISTS].

INTRODUCTION: The systemic anti-cancer approach is based on medical/pharmaceutical interventions affecting cancer cells at multiple sites, including local and distant regions. Interventions include: cytotoxic chemotherapy agents used for direct extermination of proliferating cells, hormonal interventions altering the tumor environment and affecting its ability to survive and thrive, biological drugs restoring the function defective proteins in mutated tumors, and immunological medications encouraging effective immune recognition of tumor cells and associated immune response. "Personalized medicine in oncology" aims to make anti-cancer treatment more effective and with less side effects. Potential candidates are identified both clinically per indication for therapy and ability to tolerate it, and pathologically-molecularly assessing unique biological changes in the tumor cells and/or their immediate environment. Safe and effective treatment directed to the dominant biological changes is essential as well. The biological changes in the tumor and/or its immediate environment are referred to as "bio-markers", and point to pathological changes accumulated in the tissue during the malignant transformation and tumor progression. The relevant tests for biomarker assessment are performed at the protein level or on genetic material (DNA or RNA); they require high levels of accuracy and reliability and short turnover time for results. Communication between teams assessing the molecular results and a general pathologist may facilitate high quality assessment. Laboratory tests with accurate assessment of biomarkers in over 500 genes are available in the pathology laboratories in Israel since 2020.

Hormone-Replacement Therapy and Its Association with Breast Cancer Subtypes: A Large Retrospective Cohort Study.

PURPOSE: The study examined trends in breast cancer incidence, mammography testing rates, hormone-replacement therapy (HRT) use and breast cancer subtypes in a large Israeli health maintenance organization during 2000-2014. METHODS: Annual rates of mammography tests and HRTs use were analyzed in women age ≥45. Annual incidence rates of breast cancer were analyzed in women age ≥20. Estimated annual percentage changes were used to test changes in incidence rates. Invasive breast cancer subtypes were approximated by treatments received. We compared annual rates and duration of HRTs use between women diagnosed with breast cancer and those who were not, as well as HRT use between subtypes of invasive breast cancer. RESULTS: We identified 14,092 breast cancer cases (88% invasive, 12% in situ). The age-adjusted incidence rate of invasive breast cancer peaked in 2005, consistent with increased mammography screening that year, and decreased thereafter. HRT use decreased from 13.2% in 2002 to 4.6% in 2014. The subtypes distribution of 7771 patients diagnosed with invasive breast cancer during 2007-2014 was: luminal A and B without HER2 over-expression (HR+/HER2-), 69.7%; Luminal B with HER2 over-expression (HR+/HER2+), 8.9%; Hormone receptor-negative HER2 enriched (HR-/HER2+), 5.4%; triple negative (HR-/HER2-), 10.0%; unknown, 6.0%. Overall, in women age ≥45 diagnosed with invasive breast cancer, 76-86% did not have HRT exposure vs 14-24% who were current (within 1 year before the breast cancer diagnosis), recent (within 2-5 years), or past users (>5 years). Current/recent HRT use was statistically significantly higher in luminal vs non-luminal/unknown breast cancer subtypes (13.9% vs 8.9%, respectively; p < 0.001). CONCLUSION: Our results show a decrease in breast cancer incidence that parallels the global and local decrease in HRT use. Yet, our results imply that current/recent HRT exposure may contribute to the incidence of luminal breast cancer tumors in particular. The magnitude of the effect supports findings from population-based studies.

Real-world study of PD-L1 testing patterns and treatment distribution in patients with metastatic non-small-cell lung cancer in Israel.

Aim: We describe PD-L1 testing patterns and first-line treatment for patients with metastatic non-small-cell lung cancer in a 2.3 million-member state-mandated health service in Israel. Materials & methods: Newly diagnosed stage IV non-small-cell lung cancer patients initiating systemic anticancer treatment from 1 January 2017 until 31 December 2018 were identified from the national cancer registry and Maccabi Healthcare Service database and followed until 30 June 2019. Results: The cohort consisted of 410 patients; 58% males, median age 68 years, 70% current/former smokers, 81% adenocarcinoma, 14% had brain metastases, and Eastern Cooperative Oncology Group performance status was 46/17/37% for 0-1/2-4/unknown, respectively. A total of 80% tested for PD-L1 expression, of which 47% had tumor proportion score (TPS) ≥ 50%. A total of 95% with TPS ≥ 50% and no known tumor aberrations (including EGFR mutations, and translocations in ALK and ROS1) received first-line PD-1/PD-L1-inhibitor monotherapy, and 80% of untested/TPS < 50% received platinum doublets. Conclusion: Fast uptake of testing was observed, and treatment patterns showed high adherence to guidelines.

Lay abstract We describe PD-L1 testing patterns in a cohort of 410 patients with stage IV non-small-cell lung cancer. All patients were newly diagnosed and newly treated in the years 2017 and 2018. In this cohort, 58% were males, average age was 68 years and 70% were current or former smokers. In this, 80% were tested for PD-L1 expression and 95% of those with a tumor score of >50% and no other tumor receptor mutations received first-line PD-1/PD-L1-inhibitor monotherapy (most receiving pembrolizumab). Moreover, 80% of those untested for PD-L1 or with a low tumor proportion score (<50%) received chemotherapy. After introduction in 2017, a fast uptake of PD-L1 testing was observed, and treatment patterns showed high adherence to guidelines.

Real World Analysis of Small Cell Lung Cancer Patients: Prognostic Factors and Treatment Outcomes.

In this observational study, we assessed treatment patterns and prognostic factors in patients with small cell lung cancer (SCLC) in a large state-mandated healthcare organization in Israel. Methods: All incident cases with histologically confirmed SCLC who initiated systemic anti-cancer treatment between 2011 and 2017 were identified. Treatment patterns and overall survival (OS) were evaluated for each line of therapy. Results: A total of 235 patients were identified (61% male, median age 64 years, 95% ever smokers, 64% had extensive stage). The first-line treatment was platinum-etoposide regimen for 98.7% of the cohort. The second and third-line regimen were given to 43% and 12% of patients, respectively. Mean OS for extensive and limited stage patients was 9.1 and 23.5 months respectively. In a multivariable model, increased risk for mortality was observed among patients with an ECOG performance status (PS) of 2 compared to a PS of 0-1 for the extensive stage patients (Hazard ratio (HR) = 1.63, 95% confidence ratios (CI): 1.00-2.65); and for males compared to females for the limited stage patients (HR = 2.17; 95% CI: 1.12-4.20). Regarding all 2nd line patients in a multivariable model incorporating relevant confounding factors, demonstrated a significantly better outcome with platinum-based regimens compared to topotecan. Median survival after initiation of 2nd line in platinum-sensitive patients was longer (p = 0.056) for those re-challenged with platinum-based regimen (n = 7): 6.8mo (6.1-not reported (NR)), compared with those switched to a different treatment (n = 27): 4.5 mo (2.6-6.6) for extensive stage patients, and a non-significant difference was also observed for limited stage patients. Conclusion: To our knowledge, this is one of the largest real-world studies of SCLC patients. OS for SCLC patients was similar to that reported in clinical trials. PS for extensive stage patients and sex for limited stage patients were significant correlates of prognosis. Re-challenge of the platinum-based doublet was associated with longer OS compared to switching treatment in extensive stage patients.

Does levonorgestrel-releasing intrauterine system increase breast cancer risk in peri-menopausal women? An HMO perspective.

PURPOSE: To evaluate the association between levonorgestrel-releasing intrauterine system (LNG-IUS) use and breast cancer (BC) risk. METHODS: A cohort of all Maccabi Healthcare Services (MHS) female members aged 40-50 years between 1/2003 and 12/2013 was used to identify LNG-IUS users as "cases," and 2 age-matched non-users as "controls." Exclusion criteria included: prior BC diagnosis, prior (5 years pre-study) and subsequent treatment with other female hormones or prophylactic tamoxifen. Invasive tumors were characterized by treatments received (chemotherapy, hormonal therapy, trastuzumab, or combination thereof). RESULTS: The analysis included 13,354 LNG-IUS users and 27,324 controls (mean age: 44.1 ± 2.6 vs. 44.9 ± 2.8 years; p < 0.0001). No significant differences in 5-year Kaplan-Meier (KM) estimates for overall BC risk or ductal carcinoma in situ occurrence were observed between groups. There was a trend towards higher risk for invasive BC in LNG-IUS users (5-year KM-estimate: 1.06% vs. 0.93%; p = 0.051). This difference stemmed primarily from the younger women (40-45 years; 0.88% vs. 0.69%, p = 0.014), whereas in older women (46-50 years), it was non-significant (1.44% vs. 1.21%; p = 0.26). Characterization of invasive BC by treatment demonstrated that LNG-IUS users had similar proportions of tumors treated with hormonal therapy, less tumors treated with trastuzumab, (7.5% vs. 14.5%) and more tumors treated with chemotherapy alone (25.8% vs. 14.9%; p = 0.041). CONCLUSIONS: In peri-menopausal women, LNG-IUS was not associated with an increased total risk of BC, although in the subgroup of women in their early 40's, it was associated with a slightly increased risk for invasive tumors.

Primary prevention and screening practices among long-term breast cancer survivors.

PURPOSE: Parallel to increasing survival of breast cancer (BC) patients, a need has arisen to characterize the follow-up required to improve and maintain their health. Our study aimed to assess changes in lifestyle habits over time among the study population, compare compliance rates of selected primary and secondary prevention practices between long-term BC survivors and an age-matched comparison group, and identify factors associated with compliance to these practices. METHODS: The study population comprised 250 Israeli BC survivors, diagnosed with BC between 1999 and 2003, without evidence of disease after 8-12 years, and 250 women with no cancer history, individually matched to survivors by age and area of residence. Data collection and analysis were conducted during August 2012-June 2015 and included socio-demographic variables, lifestyle habits, health promotion by the family physician, and participation in screening procedures and prevention measures. RESULTS: Higher performance rates of mammography and colonoscopy among BC survivors were observed, as well as a greater likelihood of receiving an influenza vaccine and undergoing a bone mineral density scan (adjusted-ORs: 7.7, 1.48, 1.42, and 2.59, respectively) compared to controls. Factors identified with compliance to selected practices were age, higher levels of education and income, never smoking, and strenuous physical activity. The survivors adopted healthier lifestyles, which were similar to those of women who never had cancer. CONCLUSIONS: About 10 years after BC diagnosis, the survivors generally comply with primary and secondary prevention practices.

Trends in annual drug expenditure - a 16 year perspective of a public healthcare maintenance organization.

BACKGROUND: Modern drug therapy accounts for a major share of health expenditure and challenges public provider resources. The objective of our study was to compare drug expenditure trends for ten major drug classes over 16 years at Maccabi Healthcare Services (MHS), the 2(nd) largest healthcare organization in Israel. METHODS: A retrospective analysis of drug expenditure per HMO beneficiary between the years 1998-2014. Trends in annual mean drug expenditures per MHS member were compared among 10 major drug classes. RESULTS: Average annual drug expenditure per beneficiary increased during the study period from 429.56 to 474.32 in 2014 (10.4 %). Ten drug classes accounted for 58.0 % and 77.8 % of total drug cost in 1998 and 2014, respectively. The overall distribution of drug expenditure among drug classes differed significantly between 1998 and 2014 (p < 0.001), mainly due to the increase in expenditure for cancer drugs, from 6.8 % of total drug cost to 30.3 %. In contrast, expenditures for cardiovascular drugs decreased during the same period from 16.0 to 2.7 %. Moreover, the median annual increase in net drug costs per HMO member during 1998-2014 was largest for cancer drugs (NIS 6.18/year; IQR, 1.70-9.92/year), about two-fold that of immunosuppressants, the second fastest growing drug class (NIS 2.81; IQR, 0.58-7.43/year). CONCLUSIONS: The continuous rise in anti-cancer drug expenditure puts a substantial burden on the medication budgets of public health organizations. Coordinated measures involving policy makers, physicians, and pharmaceutical companies will be required for efficient cost containment.

A Novel Computational Tool for Mining Real-Life Data: Application in the Metastatic Colorectal Cancer Care Setting.

BACKGROUND: Randomized clinical trials constitute the gold-standard for evaluating new anti-cancer therapies; however, real-life data are key in complementing clinically useful information. We developed a computational tool for real-life data analysis and applied it to the metastatic colorectal cancer (mCRC) setting. This tool addressed the impact of oncology/non-oncology parameters on treatment patterns and clinical outcomes. METHODS: The developed tool enables extraction of any computerized information including comorbidities and use of drugs (oncological/non-oncological) per individual HMO member. The study in which we evaluated this tool was a retrospective cohort study that included Maccabi Healthcare Services members with mCRC receiving bevacizumab with fluoropyrimidines (FP), FP plus oxaliplatin (FP-O), or FP plus irinotecan (FP-I) in the first-line between 9/2006 and 12/2013. RESULTS: The analysis included 753 patients of whom 15.4% underwent subsequent metastasectomy (the Surgery group). For the entire cohort, median overall survival (OS) was 20.5 months; in the Surgery group, median duration of bevacizumab-containing therapy (DOT) pre-surgery was 6.1 months; median OS was not reached. In the Non-surgery group, median OS and DOT were 18.7 and 11.4 months, respectively; no significant OS differences were noted between FP-O and FP-I, whereas FP use was associated with shorter OS (12.3 month; p <0.002; notably, these patients were older). Patients who received both FP-O- and FP-I-based regimens achieved numerically longer OS vs. those who received only one of these regimens (22.1 [19.9-24.0] vs. 18.9 [15.5-21.9] months). Among patients assessed for wild-type KRAS and treated with subsequent anti-EGFR agent, OS was 25.4 months and 18.7 months for 124 treated vs. 37 non-treated patients (non-significant). Cox analysis (controlling for age and gender) identified several non-oncology parameters associated with poorer clinical outcomes including concurrent use of diuretics and proton-pump inhibitors. CONCLUSIONS: Our tool provided insights that confirmed/complemented information gained from randomized-clinical trials. Prospective tool implementation is warranted.

Resilience and psychosocial adjustment in digestive system cancer.

The study aims to investigate the contributions of resilience, affective reactions and post traumatic growth (PTG) to psychosocial adjustment and behavioral changes among digestive system cancer patients in Israel. A sample of 200 participants, 57.5 % men (from the 46 to 70-year age range), 1-4 years following diagnosis, completed an inventory assessing demographic and medical information, resilience, current positive affect (PA) and negative affect (NA), PTG, psychosocial adjustment and retrospective report of behavioral changes following cancer treatment. Resilience, PA and NA, and PTG were related to adjustment and/or reported behavioral changes, and PA, NA and PTG mediated some of the effects of resilience on adjustment and/or reported behavioral changes. The data underline the importance of resilience, affect, and PTG in the adjustment of digestive system cancer patients. Future studies are needed to better understand the associations of resilience with psychosocial adjustment and behavioral changes. This knowledge may help improve cancer survivors' adjustment.

Where to die? That is the question: A study of cancer patients in Israel.

OBJECTIVE: Most patients prefer to die at home, but barely 30% do so. This study examines the variables contributing to dying at home. METHODS: The participants were 326 cancer patients, of both genders, with a mean age of 63.25 years, who died from 2000 to 2008 and were treated by the palliative care unit of the Barzilai Hospital. Some 65.7% died at home and 33.4% in a hospital. The data were extracted from patient files. The examined variables were demographic (e.g., age, gender, marital status, ethnic background, number of years in Israel until death), medical (e.g., age at diagnosis, diagnosis, nature of last treatment, patient received nursing care, patient given the care of a social worker, patient had care of a psychologist, family received care of a social worker, patient had a special caregiver), and sociological (e.g., having insurance, having worked in Israel, living alone or with family, living with one's children, living in self-owned or rented house, family members working). RESULTS: The findings indicate that the chances of dying at home are higher if the patient is non-Ashkenazi, the family got social worker care, the patient lived in a self-owned house, the patient lived with his family, the family members worked, and the patient's stay in Israel since immigration was longer. Logistic regression showed that all the predictors together yielded a significant model accounting for 10.9-12.3% of the variance. SIGNIFICANCE OF RESULTS: The findings suggest that dying at home requires maintaining continued care for the patient and family in a community context.

The impact of the Oncotype DX Recurrence Score on treatment decisions and clinical outcomes in patients with early breast cancer: the Maccabi Healthcare Services experience with a unified testing policy.

The Oncotype DX Recurrence Score is a validated prognosticator in oestrogen receptor positive (ER+) breast cancer. Our retrospective analysis of a prospectively defined cohort summarises the clinical implications associated with Oncotype DX testing according to the Maccabi Healthcare Services (MHS) policy. The MHS eligibility criteria for testing included ER+ N0/pN1mic invasive tumours, discussion of test implications with an oncologist, ductal carcinoma 0.6-1 cm Grade 2-3, HER2 negative ductal carcinomas with 1.1-4.0 cm Grade 1-2, or lobular carcinoma. Large (> 1 cm) Grade 3 tumours could have grade reassessed. We linked Recurrence Score results with patients' information and used chi-squared tests to assess the associations thereof. Between January 2008 and December 2011, tests were performed on 751 patients (MHS-eligible, 713); 54%, 38%, and 8% of patients had low, intermediate, and high Recurrence Score results, respectively. Recurrence Score distribution varied significantly with age (P = 0.002), with increasing Recurrence Score values with decreasing age. The proportion of patients with high Recurrence Score results varied by grade/size combination and histology, occurring in 32% of small (≤ 1 cm) Grade 3 and 3% of larger (1.1-4 cm) Grade 1 ductal tumours and only in 2% of lobular carcinomas. Chemotherapy was administered to 1%, 13%, and 61% of patients with low, intermediate, and high Recurrence Score results, respectively (P < 0.0001), but only to 2% of intermediate score patients ≥ 65 years. Luteinising-hormone-releasing hormone agonists with tamoxifen were used in 27% of low Recurrence Score patients ≤ 50 years. With a median follow-up of 26 months, no systemic recurrences were documented, whereas four patients exhibited locoregional recurrences. In summary, in this low-to-moderate risk patient population, testing identified 46% of patients as intermediate/high risk. Treatment decisions were influenced by Recurrence Score results and patients' age. The current MHS policy seems to achieve the goal of promoting chemotherapy use according to the test results in a prespecified patient population.
