Navigating the future of Alzheimer's care in Ireland - a service model for disease-modifying therapies in small and medium-sized healthcare systems.

BACKGROUND: A new class of antibody-based drug therapy with the potential for disease modification is now available for Alzheimer's disease (AD). However, the complexity of drug eligibility, administration, cost, and safety of such disease modifying therapies (DMTs) necessitates adopting new treatment and care pathways. A working group was convened in Ireland to consider the implications of, and health system readiness for, DMTs for AD, and to describe a service model for the detection, diagnosis, and management of early AD in the Irish context, providing a template for similar small-medium sized healthcare systems. METHODS: A series of facilitated workshops with a multidisciplinary working group, including Patient and Public Involvement (PPI) members, were undertaken. This informed a series of recommendations for the implementation of new DMTs using an evidence-based conceptual framework for health system readiness based on [1] material resources and structures and [2] human and institutional relationships, values, and norms. RESULTS: We describe a hub-and-spoke model, which utilises the existing dementia care ecosystem as outlined in Ireland's Model of Care for Dementia, with Regional Specialist Memory Services (RSMS) acting as central hubs and Memory Assessment and Support Services (MASS) functioning as spokes for less central areas. We provide criteria for DMT referral, eligibility, administration, and ongoing monitoring. CONCLUSIONS: Healthcare systems worldwide are acknowledging the need for advanced clinical pathways for AD, driven by better diagnostics and the emergence of DMTs. Despite facing significant challenges in integrating DMTs into existing care models, the potential for overcoming challenges exists through increased funding, resources, and the development of a structured national treatment network, as proposed in Ireland's Model of Care for Dementia. This approach offers a replicable blueprint for other healthcare systems with similar scale and complexity.

Acute hospital staff's attitudes towards dementia and perceived dementia knowledge: a cross-sectional survey in Ireland.

BACKGROUND: Little is known about staff's attitudes in Irish acute hospital settings towards people living with dementia and their perceived dementia knowledge. The aim of this study was to understand the general level of dementia knowledge and attitudes towards dementia in different types of hospital staff, as well as to explore the potential influence of previous dementia training and experience (having a family member with dementia) and the potential moderating effects of personal characteristics. This data was required to plan and deliver general and targeted educational interventions to raise awareness of dementia throughout the acute services. METHODS: A cross-sectional survey was carried out among a diverse range of hospital staff (n = 1795) in three urban acute general hospitals in Ireland, including doctors, nurses, healthcare attendants, allied professionals, and general support staff. Participants' perceived dementia knowledge and attitudes were assessed as well as their previous dementia training and experience. To measure participant's attitude towards dementia, the validated Approaches to Dementia Questionnaire (ADQ) was used. RESULTS: Hospital staff demonstrated positive attitudes towards people living with dementia, and believed they had a fair to moderate understanding of dementia. Both 'having previous dementia training' and 'having a relative living with dementia' predicted attitude towards dementia and perceived dementia knowledge. Interestingly, certain personal staff characteristics did impact dementia training in predicting attitude towards dementia and perceived dementia knowledge. CONCLUSION: This study provides a baseline of data regarding the attitudes towards dementia and perceived dementia knowledge for hospital staff in Irish acute hospitals. The results can inform educational initiatives that target different hospital staff, in order to increase awareness and knowledge to improve quality of dementia care in Irish hospitals.

Addition of gemcitabine to paclitaxel, epirubicin, and cyclophosphamide adjuvant chemotherapy for women with early-stage breast cancer (tAnGo): final 10-year follow-up of an open-label, randomised, phase 3 trial.

BACKGROUND: The tAnGo trial was designed to investigate the potential role of gemcitabine when added to anthracycline and taxane-containing adjuvant chemotherapy for early breast cancer. When this study was developed, gemcitabine had shown significant activity in metastatic breast cancer, and there was evidence of a favourable interaction with paclitaxel. METHODS: tAnGo was an international, open-label, randomised, phase 3 superiority trial that enrolled women aged 18 years or older with newly diagnosed, early-stage breast cancer who had a definite indication for chemotherapy, any nodal status, any hormone receptor status, Eastern Cooperative Oncology Group performance status of 0-1, and adequate bone marrow, hepatic, and renal function. Women were recruited from 127 clinical centres and hospitals in the UK and Ireland, and randomly assigned (1:1) to one of two treatment regimens: epirubicin, cyclophosphamide, and paclitaxel (four cycles of 90 mg/m2 intravenously administered epirubicin and 600 mg/m2 intravenously administered cyclophosphamide on day 1 every 3 weeks, followed by four cycles of 175 mg/m2 paclitaxel as a 3 h infusion on day 1 every 3 weeks) or epirubicin, cyclophosphamide, and paclitaxel plus gemcitabine (the same chemotherapy regimen as the other group, with the addition of 1250 mg/m2 gemcitabine to the paclitaxel cycles, administered intravenously as a 0·5 h infusion on days 1 and 8 every 3 weeks). Patients were randomly assigned by a central computerised deterministic minimisation procedure, with stratification by country, age, radiotherapy intent, nodal status, and oestrogen receptor and HER-2 status. The primary endpoint was disease-free survival and the trial aimed to detect 5% differences in 5-year disease-free survival between the treatment groups. Recruitment completed in 2004 and this is the final, intention-to-treat analysis. This trial is registered with EudraCT (2004-002927-41), ISRCTN (51146252), and ClinicalTrials.gov (NCT00039546). FINDINGS: Between Aug 22, 2001, and Nov 26, 2004, 3152 patients were enrolled and randomly assigned to epirubicin, cyclophosphamide, paclitaxel, and gemcitabine (gemcitabine group; n=1576) or to epirubicin, cyclophosphamide, and paclitaxel (control group; n=1576). 11 patients (six in the gemcitabine group and five in the control group) were ineligible because of pre-existing metastases and were therefore excluded from the analysis. At this protocol-specified final analysis (median follow-up 10 years [IQR 10-10]), 1087 disease-free survival events and 914 deaths had occurred. Disease-free survival did not differ significantly between the treatment groups at 10 years (65% [63-68] in the gemcitabine group vs 65% [62-67] in the control group), and median disease-free survival was not reached (adjusted hazard ratio 0·97 [95% CI 0·86-1·10], p=0·64). Toxicity, dose intensity, and a detailed safety substudy showed both regimens to be safe, deliverable, and tolerable. Grade 3 and 4 toxicities were reported at expected levels in both groups. The most common were neutropenia (527 [34%] of 1565 patients in the gemcitabine group vs 412 [26%] of 1567 in the control group), myalgia and arthralgia (207 [13%] vs 186 [12%]), fatigue (207 [13%] vs 152 [10%]), infection (202 [13%] vs 141 [9%]), vomiting (143 [9%] vs 108 [7%]), and nausea (132 [8%] vs 102 [7%]). INTERPRETATION: The addition of gemcitabine to anthracycline and taxane-based adjuvant chemotherapy at this dose and schedule confers no therapeutic advantage in terms of disease-free survival in early breast cancer, although it can cause increased toxicity. Therefore, gemcitabine has not been added to standard adjuvant chemotherapy in breast cancer for any subgroup.

Economic impact of 21-gene recurrence score testing on early-stage breast cancer in Ireland.

The 21-gene test is a validated multi-gene diagnostic test that predicts chemotherapy (CT) benefit in oestrogen receptor positive (ER+), lymph node-negative (N0) breast cancer (BC) patients (pts). Ireland was the first public health care system to reimburse this test in Europe. Study objectives were to assess the impact of this test on decision-making and to analyse the economic impact of testing. Between October 2011 and February 2013, a national, retrospective, cross-sectional observational study of ER+, N0 BC pts tested with the 21-gene test was conducted. Surveyed breast medical oncologists, provided the assumption for the decision impact analysis that grade (G) 1 pts would not have received CT before testing and G2/3 pts would have received CT before testing. Descriptive statistical analyses were performed. 592 pts were identified; Low, intermediate and high recurrence score were identified in 53, 36 and 10 % pts, respectively. 384 (70 %) pts had G2, 129 (22 %) G3 and 76 (13 %) G1 tumours. Post testing, 345 pts (59 %) experienced a change in CT decision; 339 changed to hormone therapy alone and 6 advised to receive CT. 172 (30 %) pts received CT, 12 (3.9 %) of pts with low scores, 108 (50.9 %) of intermediate risk and 50 (90.9 %) of pts with high risk scores. Net reduction in CT use was 58 % and net savings achieved were €793,565. Since public reimbursement, the introduction of the 21-gene test has resulted in a significant reduction in chemotherapy administration and cost savings for the Irish public healthcare system.

Delirium care in hospitals in Ireland on World Delirium Awareness Day 2023.

BACKGROUND: Acute, transient, but sometimes persistent, delirium is characterized by a sharp disruption in attention, consciousness, and cognitive function, and can be caused by many medications and disorders. Delirium occurrence and negative consequences, such as falls and functional decline, can be decreased with multifactorial prevention and timely detection. AIMS: To describe current clinical practice in relation to the prevention, assessment, and management of delirium in Irish hospitals; awareness-raising and educational activities; and barriers to good practice. METHODS: On World Delirium Awareness Day (15th March 2023), a global survey was conducted of delirium prevalence and care. A senior clinical staff member on each participating ward reported on delirium prevalence at 8AM and 8PM, and on usual ward practice; this data was entered into an online survey by a data collector (typically a clinician from the site, visiting several wards to record data). This study reports data from Irish hospitals. RESULTS: In total, 132 wards from 15 hospitals across Ireland participated. Almost 60% of wards used 'personal judgment' for delirium assessment. Having at least one delirium training session in the preceding year was associated with greater use of a formal assessment tool (60.3% versus 18.8%; p < 0.001). Wards reported staff training/education as the main priority to improve care, but 72.7% of wards identified insufficient time to train staff as a key barrier. CONCLUSIONS: Clinical practice related to delirium care requires improvement. Awareness raising and staff training require more focus and time in busy clinical settings.

Assessing the real-world cost-effectiveness of adjuvant trastuzumab in HER-2/neu positive breast cancer.

BACKGROUND: Among women with surgically removed, high-risk HER-2/neu-positive breast cancer, trastuzumab has demonstrated significant improvements in disease-free and overall survival. The objective of this study is to evaluate the cost-effectiveness of the currently recommended 12-month adjuvant protocol of trastuzumab using a Markov modeling approach and real-world cost data. METHODS: A 10-health-state Markov model tracked patients' quarterly transitions between health states in the local and advanced states of breast cancer. Clinical data were obtained from the joint analysis of the National Surgical Adjuvant Breast and Bowel Project and North Central Cancer Treatment Group, as well as from the metastatic study conducted by Norum et al. Clinical outcomes were adjusted for quality of life using utility estimates published in a systematic review. Real cost data were obtained from the British Columbia Cancer Agency and were evaluated from a payer perspective. Costs and utilities were discounted at 5% per year, respectively, for a 28-year time horizon. RESULTS: In the base case analysis, treatment with a 12-month adjuvant trastuzumab regimen resulted in a gain of 1.38 quality-adjusted life years or 1.17 life years gained at a cost of $18,133 per patient. Thus, the cost per QALY gained for the base case is $13,095. Cost per LYG is $15,492. CONCLUSIONS: Over the long term, treatment of HER-2/neu mutation positive breast cancer with a 12-month protocol of trastuzumab in the adjuvant setting is predicted to be cost-effective in a Canadian context.

Interval cancer audit and disclosure in cervical screening programmes: An international survey.

BACKGROUND: Legal cases involving the National Cervical Screening Programme in Ireland following non-disclosure of an interval cervical cancer audit prompted this first international comparative survey of interval cervical cancer audit. METHODS: A survey of 22 international population-based cervical screening programmes was conducted, to determine if they undertook audit of invasive cervical cancers. Those countries/regions that perform reviews were asked (i) how the audit was undertaken, including how the reviews were performed and how they controlled for retrospective bias, (ii) how women are informed of the audit process and how their consent is obtained, and (iii) how audit results were disclosed to patients. RESULTS: Seventeen countries/regions invited completed the survey (77%); 65% (11/17) have an audit process for interval cervical cancers. Five perform individual patient reviews; three perform programme-wide review, with calculation of interval cancer detection rates; one routinely performs programme-wide review with calculation of interval cancer detection rates and offers individual reviews, and one routinely performs local hospital-level reviews. In the remaining country/region, hospital laboratories audit cancers, with a national audit process for all cervical cancers. Varying methodologies for retrospective cytology review were employed; four include control samples, with a ratio varying from 1:1 to 1:2. Three conduct a blinded review. Most countries/regions do not discuss interval cancer audit with participants and 3/11 (27.3%) inform women when a cervical cancer audit takes place. Disclosure is limited and variable. CONCLUSION: The responses suggest that there is no consistent approach to audit of interval cervical cancers or to disclosure of audit results.

Sequential docetaxel as adjuvant chemotherapy for early breast cancer (TACT): an open-label, phase III, randomised controlled trial.

BACKGROUND: Incorporation of a taxane as adjuvant treatment for early breast cancer offers potential for further improvement of anthracycline-based treatment. The UK TACT study (CRUK01/001) investigated whether sequential docetaxel after anthracycline chemotherapy would improve patient outcome compared with standard chemotherapy of similar duration. METHODS: In this multicentre, open-label, phase III, randomised controlled trial, 4162 women (aged >18 years) with node-positive or high-risk node-negative operable early breast cancer were randomly assigned by computer-generated permuted block randomisation to receive FEC (fluorouracil 600 mg/m(2), epirubicin 60 mg/m(2), cyclophosphamide 600 mg/m(2) at 3-weekly intervals) for four cycles followed by docetaxel (100 mg/m(2) at 3-weekly intervals) for four cycles (n=2073) or control (n=2089). For the control regimen, centres chose either FEC for eight cycles (n=1265) or epirubicin (100 mg/m(2) at 3-weekly intervals) for four cycles followed by CMF (cyclophosphamide 600 mg/m(2), methotrexate 40 mg/m(2), and fluorouracil 600 mg/m(2) at 4-weekly intervals) for four cycles (n=824). The primary endpoint was disease-free survival. Analysis was by intention to treat (ITT). This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN79718493. FINDINGS: All randomised patients were included in the ITT population. With a median follow-up of 62 months, disease-free survival events were seen in 517 of 2073 patients in the experimental group compared with 539 of 2089 controls (hazard ratio [HR] 0.95, 95% CI 0.85-1.08; p=0.44). 75.6% (95% CI 73.7-77.5) of patients in the experimental group and 74.3% (72.3-76.2) of controls were alive and disease-free at 5 years. The proportion of patients who reported any acute grade 3 or 4 adverse event was significantly greater in the experimental group than in the control group (p<0.0001); the most frequent events were neutropenia (937 events vs 797 events), leucopenia (507 vs 362), and lethargy (456 vs 272). INTERPRETATION: This study did not show any overall gain from the addition of docetaxel to standard anthracycline chemotherapy. Exploration of predictive biomarker-defined subgroups might have the potential to better target the use of taxane-based therapy.

Epirubicin and cyclophosphamide, methotrexate, and fluorouracil as adjuvant therapy for early breast cancer.

BACKGROUND: The National Epirubicin Adjuvant Trial (NEAT) and the BR9601 trial examined the efficacy of anthracyclines in the adjuvant treatment of early breast cancer. METHODS: In NEAT, we compared four cycles of epirubicin followed by four cycles of cyclophosphamide, methotrexate, and fluorouracil (CMF) with six cycles of CMF alone. In the BR9601 trial, we compared four cycles of epirubicin followed by four cycles of CMF, with eight cycles of CMF alone every 3 weeks. The primary end points were relapse-free and overall survival. The secondary end points were adverse effects, dose intensity, and quality of life. RESULTS: The two trials included 2391 women with early breast cancer; the median follow-up was 48 months. Relapse-free and overall survival rates were significantly higher in the epirubicin-CMF groups than in the CMF-alone groups (2-year relapse-free survival, 91% vs. 85%; 5-year relapse-free survival, 76% vs. 69%; 2-year overall survival, 95% vs. 92%; 5-year overall survival, 82% vs. 75%; P<0.001 by the log-rank test for all comparisons). Hazard ratios for relapse (or death without relapse) (0.69; 95% confidence interval [CI], 0.58 to 0.82; P<0.001) and death from any cause (0.67; 95% CI, 0.55 to 0.82; P<0.001) favored epirubicin plus CMF over CMF alone. Independent prognostic factors were nodal status, tumor grade, tumor size, and estrogen-receptor status (P<0.001 for all four factors) and the presence or absence of vascular or lymphatic invasion (P=0.01). These factors did not significantly interact with the effect of epirubicin plus CMF. The overall incidence of adverse effects was significantly higher with epirubicin plus CMF than with CMF alone but did not significantly affect the delivered-dose intensity or the quality of life. CONCLUSIONS: Epirubicin plus CMF is superior to CMF alone as adjuvant treatment for early breast cancer. (ClinicalTrials.gov number, NCT00003577 [ClinicalTrials.gov].).

International collaborations in cancer control and the Third International Cancer Control Congress.

Over the past few decades, there has been growing support for the idea that cancer needs an interdisciplinary approach. Therefore, the international cancer community has developed several strategies as outlined in the WHO non-communicable diseases Action Plan (which includes cancer control) as the World Health Assembly and the UICC World Cancer Declaration, which both include primary prevention, early diagnosis, treatment, and palliative care. This paper highlights experiences/ideas in cancer control for international collaborations between low, middle, and high income countries, including collaborations between the European Union (EU) and African Union (AU) Member States, the Latin-American and Caribbean countries, and the Eastern Mediterranean countries. These proposals are presented within the context of the global vision on cancer control set forth by WHO in partnership with the International Union Against Cancer (UICC), in addition to issues that should be considered for collaborations at the global level: cancer survival (similar to the project CONCORD), cancer control for youth and adaptation of Clinical Practice Guidelines. Since cancer control is given lower priority on the health agenda of low and middle income countries and is less represented in global health efforts in those countries, EU and AU cancer stakeholders are working to put cancer control on the agenda of the EU-AU treaty for collaborations, and are proposing to consider palliative care, population-based cancer registration, and training and education focusing on primary prevention as core tools. A Community of Practice, such as the Third International Cancer Control Congress (ICCC-3), is an ideal place to share new proposals, learn from other experiences, and formulate new ideas. The aim of the ICCC-3 is to foster new international collaborations to promote cancer control actions in low and middle income countries. The development of supranational collaborations has been hindered by the fact that cancer control is not part of the objectives of the Millennium Development Goals (MGGs). As a consequence, less resources of development aids are allocated to control NCDs including cancer.

The impact of the 21-gene recurrence score (Oncotype DX) on concordance of adjuvant therapy decision making as measured by the Liverpool Systemic Therapy Adjuvant Decision Tool.

PURPOSE: The 21-gene recurrence score (Oncotype DX) (RS) informs systemic therapy decision making in ER-positive HER2-negative early breast cancer (BC). To date no study has described the more nuanced discussions that take place regarding systemic therapy or the impact of the RS on concordance in such decision making. Here we utilized a novel decision making tool to assess the impact of the RS on decision making as well as concordance of treatment recommendations. PATIENTS AND METHODS: The clinicopathological information (CPI) of 50 BCs without and with the RS were presented to a panel of breast oncologists in a simulated MDT. The Liverpool Adjuvant Systemic Therapy Decision Tool (LASTDT) was developed and used to categorize treatment recommendations. Outcome measures included the impact of the RS on decisiveness and concordance in decision making and its impact on treatment recommendations. RESULTS: Availability of the RS increased definitive decision making from 8% (4/50) to 56% (28/50) [χ2 = 79.35, p < 0.001] and altered the LASTDT category in 68% (34/50) of cases (p < 0.001), 74% of which were to forgo chemotherapy. With knowledge of RS, universal concordance rose from 14% to 64% [K = 0.328: K = 0.729]. CONCLUSIONS: The RS improves certainty of decision making as well as concordance amongst oncologists. This provides evidence that the availability of the RS can improve consistency of decision making amongst oncologists and thus helps to ensure patients are managed consistently. This is particularly important when patients are managed in a loco-regional, multidisciplinary team manner where heterogeneous decisions can lead to disparity in care.

Introduction of combined CHOP plus rituximab therapy dramatically improved outcome of diffuse large B-cell lymphoma in British Columbia.

PURPOSE: For more than two decades, cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) has been the standard therapy for diffuse large B-cell lymphoma (DLBCL). The addition of rituximab to CHOP has been shown to improve outcome in elderly patients with DLBCL. We conducted a population-based analysis to assess the impact of this combination therapy on adult patients with DLBCL in the province of British Columbia (BC). METHODS: We compared outcomes during a 3-year period; 18 months before (prerituximab) and 18 months after (postrituximab) institution of a policy recommending the combination of CHOP and rituximab for all patients with newly diagnosed advanced-stage (stage III or IV or stage I or II with "B" symptoms or bulky [> 10 cm] disease) DLBCL. RESULTS: A total of 292 patients were evaluated; 140 in the prerituximab group (median follow-up, 42 months) and 152 in the postrituximab group (median follow-up, 24 months). Both progression-free survival (risk ratio, 0.56; 95% CI, 0.39 to 0.81; P = .002) and overall survival (risk ratio, 0.40; 95% CI, 0.27 to 0.61, P < .0001) were significantly improved in the postrituximab group. After controlling for age and International Prognostic Index score, era of treatment remained a strong independent predictor of progression-free survival (risk ratio, 0.59; 95% CI, 0.41 to 0.85; P = .005) and overall survival (risk ratio, 0.43; 95% CI, 0.29 to 0.66; P < .001). The benefit of treatment in the postrituximab era was present regardless of age. CONCLUSION: The addition of rituximab to CHOP chemotherapy has resulted in a dramatic improvement in outcome for DLBCL patients of all ages in the province of BC.

Brief chemotherapy and involved-region irradiation for limited-stage diffuse large-cell lymphoma: an 18-year experience from the British Columbia Cancer Agency.

PURPOSE: To evaluate clinical outcome of patients with limited-stage diffuse large-cell lymphoma (DLCL) treated with three cycles of chemotherapy followed by involved-region irradiation (IRRT). PATIENTS AND METHODS: Adults with limited-stage DLCL were treated with brief doxorubicin-containing chemotherapy regimens between 1980 and 1998. IRRT was administered 3 to 4 weeks after the third chemotherapy treatment in a dose equivalent to 30 Gy in 10 fractions. RESULTS: Three hundred and eight patients (median age, 64 years) were included, and 299 experienced complete remission. After a median follow-up of 86 months, 64 patients developed progressive disease, and 104 patients died (43 from lymphoma, three from toxicity, and 58 from other causes). Actuarial overall and progression-free survival (PFS) rates were, respectively, 80% and 81% at 5 years and 63% and 74% at 10 years. For subgroups identified using the Miller modification of the International Prognostic Index (IPI), the overall survival rates at 5 and 10 years were, respectively, 97% and 89% (no factors), 77% and 56% (one or two factors), and 58% and 48% (three or four factors), and the 5-year and 10-year PFS rates were, respectively, 94% and 89% (no factors), 79% and 73% (one or two factors), and 60% and 50% (three or four factors). Men with testicular presentation, had a definitely inferior outcome. CONCLUSION: Long-term outcome with three cycles of doxorubicin-based chemotherapy and IRRT confirms that this is a successful approach for the majority of patients with limited-stage DLCL. Subgroups with worse prognoses can be identified, and these patients should be offered alternative treatment approaches.

Outcomes in elderly patients with advanced colorectal cancer treated with capecitabine: a population-based analysis.

BACKGROUND: Toxicity concerns impact the delivery of palliative chemotherapy to elderly patients with advanced colorectal cancer (CRC). Capecitabine was approved for funding in the province of British Columbia in the spring of 2002 as an oral chemotherapeutic option for metastatic CRC. PATIENTS AND METHODS: We conducted a population-based study to assess temporal trends in the use of systemic agents in elderly patients. Patients aged > or = 70 years with metastatic CRC diagnosed between January 1, 2000, and December 31, 2000, and between June 1, 2002, and May 31, 2003, were identified through the British Columbia Cancer Agency Registry. The time cohorts were before and after the provincial approval of capecitabine. Data were obtained regarding demographics, systemic therapies, and outcomes. RESULTS: In cohort A, 35 of 89 patients (39%) were treated with chemotherapy. In the treated versus untreated groups of cohort A, 66% and 57% of patients were male, median ages were 73 years and 76 years, and liver metastasis was seen in 69% and 70% of patients, respectively. In cohort B, 36 of 78 patients (46%) were treated with systemic therapy. In the treated versus untreated groups of cohort B, 58% and 40% of patients were male, median ages were 75 years and 78.5 years, and liver metastasis was seen in 78% and 64% of patients. The most common first-line chemotherapy regimens used in cohort A included single-agent 5-FU in 66%, irinotecan-based regimens in 17%, and other regimens in 11%. First-line chemotherapy in cohort B included capecitabine in 47%, oxaliplatin-based regimens in 19%, and irinotecan-based regimens in 17%. The median times to treatment failure resulting from toxicity, disease progression, or death were 37 days in cohort A and 61 days in cohort B. Overall survival between the 2 time cohorts did not differ significantly. Toxicities resulting in dose delay and/or reduction were comparable. CONCLUSION: We conclude that, in patients > or = 70 years of age with advanced CRC, single-agent 5-FU and capecitabine were the favored palliative regimens in British Columbia in 2000 and 2002, respectively. Capecitabine was well tolerated, and both treatments demonstrated similar survival. There was a trend observed toward a greater proportion of patients being offered systemic therapy in the 2002 cohort; however, the difference was not statistically significant.

Eribulin for the treatment of advanced or metastatic breast cancer: a NICE single technology appraisal.

The National Institute for Health and Care Excellence (NICE) invited the manufacturer of eribulin (Eisai Ltd) to submit evidence for the clinical and cost effectiveness of eribulin as treatment for patients with locally advanced or metastatic breast cancer (LABC/MBC) pre-treated with at least two chemotherapy regimens. This article summarizes the review of evidence by the Evidence Review Group (ERG) and provides a summary of the NICE Appraisal Committee's (AC's) decision. The clinical evidence was derived from a multi-centred, open-label, randomized, phase III study comparing eribulin with treatment of physician's choice (TPC) in 762 patients with LABC/MBC. Clinical effectiveness results were submitted for two populations: the overall intention-to-treat (ITT) population and a subset (n = 488) that included only patients from North America, Western Europe and Australia (Region 1). For the primary endpoint of overall survival (OS), a primary analysis (after 55 % of patients had died) and an updated analysis (after 77 % of patients had died) were conducted. In the ITT population, treatment with eribulin was associated with a significant improvement in median OS compared with TPC in both primary [difference in median OS 2.5 months; hazard ratio (HR) 0.81, 95 % confidence interval (CI) 0.66-0.99] and updated analyses (2.7 months; HR 0.81, 95 % CI 0.67-0.96). A statistically significant improvement in progression-free survival (PFS) was reported for eribulin compared with TPC when assessed by the investigator (difference in median PFS 1.48 months; HR 0.76, 95 % CI 0.64-0.90), but not when assessed by the ERG (1.44 months; HR 0.87, 95 % CI 0.71-1.05). Gains in OS were greater for Region 1 patients than for the ITT population (3.1 vs. 2.7 months). Health-related quality of life (HRQoL) data suggested a benefit for eribulin responders, but was based on phase II studies. In the eribulin arm, serious adverse events included febrile neutropenia (4.2 %) and neutropenia (1.8 %), with peripheral neuropathy being the most common reason for treatment discontinuation. The manufacturer's economic evaluation using Patient Access Scheme costs reported a base-case incremental cost-effectiveness ratio (ICER) for eribulin versus TPC (Region 1) of £46,050 per quality-adjusted life year gained (corrected to £45,106 when an erroneous data entry was removed). The ERG's revised ICERs were £61,804 for Region 1 and £76,110 for the overall population. The AC concluded that the evidence had not demonstrated sufficient benefit in OS, cost effectiveness or HRQoL and that eribulin was not recommended for use in this patient group.

Treatment of elderly Hodgkin's lymphoma patients with a novel 5-drug regimen (ODBEP): a phase II study.

Elderly patients with Hodgkin's lymphoma (HL) have a worse outcome than young patients. In an effort to improve the outcome in elderly HL patients, we used a 5-drug chemotherapy regimen called ODBEP (vincristine, doxorubicin, bleomycin, etoposide, prednisone) from 1986-1995. We hoped that by increasing dose intensity through delivery of treatment without delays, and increasing the number of non-cross-resistant chemotherapeutic drugs that were selected for minimal cumulative myelotoxicity, we might improve the cure rate in elderly patients with Hodgkin's lymphoma. Comparison was made with a similar group of patients treated from 1981-1986 with MOPP/ABV-variant chemotherapy. Ninety-nine patients who were 65 years or older, were diagnosed with HL from 1981-1995. Seventy-one patients had advanced disease and 55 of this group were treated with curative intent using multi-agent chemotherapy (ODBEP = 38; MOPP/ABV-variant = 17). ODBEP and MOPP/ABV-type treatment gave a median survival of 43 and 39 months, with 5-year overall survival (OS) of 42 and 32%, respectively. There was no statistically significant difference in OS or disease specific survival between the treatments. Both treatments were well tolerated, but ODBEP was less myelotoxic. ODBEP patients had a relative risk of 0.47 of developing febrile neutropenia compared to the MOPP/ABV-variant patients. In conclusion, treatment of elderly Hodgkin's lymphoma patients with ODBEP resulted in a similar OS and disease-specific survival compared to those treated with MOPP/ABV type chemotherapy, but appeared to be less toxic.

Survival for metastatic colorectal cancer in the bevacizumab era: a population-based analysis.

BACKGROUND: As of 2006, bevacizumab was available for the treatment of metastatic colorectal cancer (mCRC) in British Columbia (BC). This study compares survival between referred patients diagnosed with mCRC in 2003/2004 (pre-bevacizumab era) and 2006 (bevacizumab era). PATIENTS AND METHODS: The BC cancer agency (BCCA) is a cancer network treating approximately 60% of patients with mCRC in BC. For this study, all patients in the BCCA diagnosed with mCRC in 2003/2004 and 2006 were included. The primary objective was to compare overall survival (OS) between the 2 cohorts. RESULTS: One thousand four hundred seventeen patients were included: 969 from 2003/2004, and 448 from 2006. Between 2003/2004 and 2006, the proportion of patients treated with systemic therapy for mCRC increased (61.1% to 67.6%; P = .02). The only significant difference in treatment between the cohorts was in the proportion of patients who received bevacizumab (5.9% to 30.6%; P < .001). Median OS significantly differed between the 2 cohorts (13.8 to 17.3 months; P < .001). Median OS for patients who received systemic therapy increased (18.6-23.6 months; P = .001). Median OS for patients who did not receive systemic therapy was unchanged (6.1-5.9 months; P = .65). CONCLUSION: In this population-based study, median OS for mCRC significantly increased between 2003/2004 and 2006. An increase in the proportion of patients treated with systemic therapy, and the addition of bevacizumab to chemotherapy, seem to have contributed to this improvement in survival.

Access to cancer drugs in Canada: looking beyond coverage decisions.

OBJECTIVE: To examine variation in patients' access to a set of cancer drugs through publicly funded provincial drug programs. DATA SOURCES/STUDY DESIGN: We surveyed provincial drug program managers about their highest-expenditure intravenous and oral cancer drugs. We then investigated whether the same cancer drugs account for the highest expenditures across the provincial programs. We also compared the rates at which these drugs are accessed through these programs. PRINCIPAL FINDINGS: While there is moderate consistency in the selection of cancer drugs that account for the highest provincial expenditures, considerable differences were found in the rates at which some drugs are accessed across provincial programs. CONCLUSIONS: The study demonstrates the existence of interprovincial variation in publicly funded access to cancer drugs even after these drugs have been approved for public coverage.

Randomized trial of tamoxifen versus combined tamoxifen and octreotide LAR Therapy in the adjuvant treatment of early-stage breast cancer in postmenopausal women: NCIC CTG MA.14.

PURPOSE: Somatostatin analogs act directly on breast cancer cells and indirectly on insulin and insulin-like growth factor 1 (IGF-1) levels. This trial was undertaken to assess whether octreotide would lower insulin and IGF-1 levels and reduce risk of breast cancer recurrence. PATIENTS AND METHODS: The NCIC CTG MA.14 (NCIC Clinical Trials Group MA.14) trial randomly assigned postmenopausal women to 5 years of tamoxifen 20 mg daily (TAM) or TAM plus 2 years of octreotide 90 mg depot intramuscular injections monthly (TAM-OCT) as adjuvant therapy. The primary end point was event-free survival (EFS). Secondary end points were relapse-free survival (RFS), overall survival (OS), toxicity, and effects of treatment on IGF physiology. RESULTS: Among 667 women with a median follow-up of 7.9 years, 220 events occurred-108 with TAM-OCT and 112 with TAM. Adjusted hazard ratios (HRs; TAM-OCT to TAM) were 0.93 for EFS (95% CI, 0.71 to 1.22; P = .62), 0.84 for RFS (95% CI, 0.59 to 1.18; P = .31), and 0.97 for OS (95% CI, 0.69 to 1.37; P = .86). Among patients with normal baseline gallbladder imaging, cholecystectomy was required in 23.0% of those receiving TAM-OCT but in only 1.4% of those receiving TAM (P < .001). At 4 months, TAM-OCT had significantly (P < .001) lowered IGF-1, IGF binding protein 3, and C-peptide levels. Older age (P = .02), tumor size (P = .001), nodal status (P = .01), high C-peptide levels (P < .001), and higher body mass index (BMI) in models excluding C-peptide (P < .001) were associated with poorer EFS in multivariate analysis. CONCLUSION: Octreotide-related changes in circulating IGF-1 and C-peptide levels were statistically significant. Octreotide did not add significant clinical benefit. High C-peptide levels (surrogate for insulin secretion rate) and high BMI were associated with poor outcome.
