Changes in essential cancer medicines and association with cancer outcomes: an observational study of 158 countries

BACKGROUND

Cancer is a major cause of mortality worldwide, and differences in cancer mortality rates between countries are, in part, due to differences in access to cancer care, including medicines. National essential medicines lists (NEMLs) play a role in prioritization of healthcare expenditure and access to medicines. We examined the association between amenable cancer mortality and listing medicines used in the management of eight cancers (non-melanoma skin, uterine, breast, Hodgkin lymphoma, colon, leukemia, cervical, and testicular) in national essential medicines lists of 158 countries and summarized changes to the inclusion of cancer treatments in NEMLs.

METHODS

We conducted a cross-sectional examination of NEMLs for 158 countries, which were obtained in May 2023. We identified medicines used to treat each of the eight cancers and determined the number of medicines listed by NEMLs for each cancer. We conducted multiple linear regressions to examine the association between the number of medicines listed on the NEMLs and cancer mortality.

RESULTS

We found associations between cancer medicine listing and outcomes for six of the eight examined cancers (non-melanoma skin cancer (p = 0.001), uterine cancer (p = 0.006), breast cancer (p = 0.001), Hodgkin lymphoma (p = 0.021), colon cancer (p = 0.006), and leukemia (p = 0.002)), when adjusting for healthcare expenditure and population size.

CONCLUSION

There was an association between listing cancer medicines on NEMLs and cancer mortality. Further research is required to explore how cancer mortality may be impacted by other cancer interventions, as well as policies to improve equitable access to cancer care.

High risk Langerhans cell histiocytosis in children: the role of salvage in improving the outcome. A single center experience

BACKGROUND

In pediatric multi-system high risk organs (RO +) Langerhans cell histiocytosis (LCH), failing 1st line treatment has the highest mortality. We aim to present the outcome of failure of 1st line whether due to disease progression (DP) at end of induction or reactivation (REA) after initial better status response.

PATIENTS AND METHODS

Sixty-seven RO + LCH patients with hemopoietic, hepatic or splenic involvement, treated between 2007 and 2019 were retrospectively analyzed. The median follow-up (IQR) is 6 years (4-8.8 y).They were subjected to 2 eras of treatment; one with salvage by 2-Cda based regimen (2-CdABR) and another without.

RESULTS

Of 67 patients, M/F 40/27, median age 1.74 y (0.2-10 y), 42 failed 1st line (62.7%). Of them DP n = 22 (52%) and REA n = 20 (48%). Of those with DP, 9/22 patients received 2-CdABR, where 5 survived in better status. While the remaining 13 did not receive 2-CdABR and all of them died. Otherwise, of those with REA, 12/20 reactivated on RO + mode. Of them, 8/12 received 2-CdABR, where only one survived in better status and the remaining 4 received vinblastine-based regimen,where 2 died and 2 were rescued. RO + 5-year overall survival (OS) was 65% (CI 95% 54 -78) while the event free survival (EFS) 36% (26.3-50.1). The OS of DP 27% (14-54) versus REA 67% (49-93) p 0.004. OS of DP with 2-CdABR 56% (31-97.7) versus 8% without (2-51), p < 0.001. While OS of REA with 2-CdABR 38% (13-100) versus 74% without (53-100) p 0.7.

CONCLUSION

Survival of RO + remains limited. Failure of 1st line in RO + due to DP carries worse prognosis in relation to REA. In DP those who were not salvaged by 2-CdABR, showed dismal outcome. This could not be shown when applied in REA.

Anticancer medicines in Pakistan: An analysis of essential medicines lists

OBJECTIVE

The lack of anticancer drugs for curative and supportive purposes is the critical reason for the low survival rate in low-and-middle-income countries. This study aims to analyze whether the National Essential Medicines List (NEML) and Registered Essential Medicines List (REML) are in concordance with the World Health Organization (WHO) Essential Medicines List (EML) and whether the formularies prevalent in the country are parallel to each other and to the NEML.

METHOD

An observational study design was used in which antineoplastic drugs from the 2021 NEML and REML were compared with 2021 WHO EML to evaluate their availability in Pakistan. Market access was determined. Moreover, the formularies of six different hospital types were compared with each other and with the NEML, and REML to estimate the availability within hospitals.

RESULTS

There were 66 anticancer drugs in 2021 WHO EML and all were found in Pakistan's 2021 NEML but only 48 drugs (73%) were found in the REML. Hydroxycarbamide and dasatinib were two registered drugs absent in all hospitals' formularies. The market access for anticancer medicines was 73% (48 of 66). Semigovernment hospital (86%) has the highest availability, followed by the government hospital (80%). All the hospitals have unregistered drugs including bortezomib, lenalidomide, and mesna.

CONCLUSION

Pakistan's NEML adopts WHO EML abruptly but all medicines are not registered. The hospitals are trying their best to increase availability but optimum drug regulations to revise NEML based on the country's requirements and emphasizing registration of anticancer medicines are needed to improve the country's availability of antineoplastic agents.

Essential cancer medicines and cancer outcomes: Cross-sectional study of 124 countries

BACKGROUND

Cancer is the second leading cause of death worldwide. Alongside other interventions, access to certain medicines may decrease cancer-associated mortality. Listing medicines on national essential medicines lists may improve health outcomes. We examine the association between cancer mortality amenable to care and the listing of cancer medicines on national essential medicines lists (NEMLs) of 124 countries.

METHODS

In this cross-sectional study, we determined the number of medicines used to treat eight cancers on NEMLs and used multiple linear regression to analyze the association between cancer health outcome scores and the number of medicines on NEMLs while controlling for GDP. A sensitivity analysis was also conducted using selected medicines.

FINDINGS

The number of cancer medicines on NEMLs was not associated with cancer health outcome scores when GDP was controlled for non-melanoma skin (p = 0.224), uterine (p = 0.221), breast (p = 0.145), Hodgkin's lymphoma (p = 0.697), colon (p = 0.299), leukemia (p = 0.103), cervical (p = 0.834), and testicular cancers (p = 0.178).

INTERPRETATION

There was a weak association between listing medicines for eight cancers in NEMLs and amenable mortality. Further studies are required to explore association between cancer health outcomes and other factors such as actual availability of medicines listed, access to surgeries, accurate diagnosis, radiotherapy, and early detection.

The impact of China's zero markup drug policy on drug costs for managing Parkinson's disease and its complications: an interrupted time series analysis

Background

In April 2009, the Chinese government launched Zero Markup Drug Policy (ZMDP) to adjust medical institutions' revenue and expenditure structures.

Objective

This study evaluated the impact of implementing ZMDP (as an intervention) on the drug costs for managing Parkinson's disease (PD) and its complications from the healthcare providers' perspective.

Methods

The drug costs for managing PD and its complications per outpatient visit or inpatient stay were estimated using electronic health data from a tertiary hospital in China from January 2016 to August 2018. An interrupted time series analysis was conducted to evaluate the immediate change following the intervention (step change, β₁) and the change in slope, comparing post-intervention with the pre-intervention period (trend change, β₂). Subgroup analyses were conducted in outpatients within the strata of age, patients with or without health insurance, and whether drugs were listed in the national Essential Medicine List (EML).

Results

Overall, 18,158 outpatient visits and 366 inpatient stays were included. Outpatient (β₁ = -201.7, 95%CI: -285.4, -117.9) and inpatient (β₁ = -372.1, 95% CI: -643.6, -100.6) drug costs for managing PD significantly decreased when implementing ZMDP. However, for outpatients without health insurance, the trend change in drug costs for managing PD (β₂ = 16.8, 95% CI: 8.0, 25.6) or PD complications (β₂ = 12.6, 95% CI: 5.5, 19.7) significantly increased. Trend changes in outpatient drug costs for managing PD differed when stratifying drugs listed in EML (β₂ = -1.4, 95% CI: -2.6, -0.2) or not (β₂ = 6.3, 95%CI: 2.0, 10.7). Trend changes of outpatient drug costs for managing PD complications significantly increased in drugs listed in EML (β₂ = 14.7, 95% CI 9.2, 20.3), patients without health insurance (β₂ = 12.6, 95% CI 5.5, 19.7), and age under 65 (β₂ = 24.3, 95% CI 17.3, 31.4).

Conclusions

Drug costs for managing PD and its complications significantly decreased when implementing ZMDP. However, the trend in drug costs increased significantly in several subgroups, which may offset the decrease at the implementation.

Essential tuberculosis medicines and health outcomes in countries with a national essential medicines list

Background

Tuberculosis (TB) remains a major cause of morbidity and mortality globally despite effective treatments. Along with high-quality health services, essential medicines are a key tool in curbing TB related mortality. Examining relationships between listing TB medicines on national essential medicines lists (NEMLs) and population health outcomes related to amenable mortality is one way to assess TB care.

Methods

In this cross-sectional study of 137 countries, we used linear regression to examine the relationship between the number of TB medicines listed on NEMLs and TB related mortality while controlling for country income, region and TB burden.

Results

Most countries listed essential TB medicines to treat latent, drug-sensitive and disseminated TB but few listed enough for multi-drug resistant TB (MDR-TB) therapy. The total number of TB medicines listed ranged from 1 to 29 (median: 19, interquartile range: 15 to 22). Over 75% of the variation in health outcomes were explained by the number of TB medicines listed, gross domestic product (GDP) per capita, region and high-burden MDR-TB status. The number of TB medicines listed was not associated with TB mortality.

Conclusion

Most countries list essential TB treatments and the variation in TB outcomes is explained by other factors such as GDP.

Cancer Drugs in Asian Populations: Availability, Accessibility, and Affordability

Accessibility to effective cancer treatments is a goal of Universal Health Coverage; yet, achieving this in the context of escalating costs in a diversity of Asian nations with different socioeconomic development is extremely challenging. Value-based assessments within the context of each health care system, financing infrastructure that will facilitate appropriate prioritization of high-cost medications, transparency in international pricing and reducing out-of-pocket costs through national insurance programs are measures that Asian countries should take toward Universal Health Coverage for cancer care. Encouraging sharing data on pricing through the World Health Organization, sharing expertise in health technology assessments and regulatory approvals, and exploring bulk negotiations would also strengthen the process of price control. For each individual country, rational selection of national cancer formulary, aiming at price reduction and sound procurement strategies for each drug, is important toward ensuring affordable access to quality cancer medications.

Retrospective cohort analysis of prescription patterns of cancer medications during periods of drug stockouts in Botswana

OBJECTIVE

Cancer drug stockouts occur at high frequencies globally, however, their effects on treatment are understudied in sub-Saharan Africa (SSA). We aimed to determine whether causes of suboptimal cancer treatment prescriptions differed between periods of stockout and full treatment supply.

DESIGN

A retrospective cohort study of systemic therapy prescriptions for patients diagnosed with the twelve most common solid tumour cancers treated in 2016.

SETTING

Princess Marina Hospital in Gaborone, Botswana.

PARTICIPANTS

Patients in the retrospective cohort who experienced any suboptimal treatment events, defined as ≥7 days delay or switch from guideline-concordant initiated therapy.

PRIMARY AND SECONDARY OUTCOME MEASURES

Frequency of delays and patterns of prescription changes for specific regimens and cancer types.

RESULTS

167/378 patients contributed to 320 suboptimal events (115 therapy switches, 167 delays and 38 events with both), over 1452 total chemotherapy cycles received. Events during stockout were 43% delays, 43% switches and 14% both during stockout periods and 67.2% delays, 24.4% switches and 8.4% both during non-stockout periods (p<0.001). Majority of switches involved de-escalation of initially prescribed guideline-recommended regimens in patients with breast cancer, Kaposi sarcoma and patients with colorectal cancer, which occurred more frequently during periods of drug stockouts. Among patients with breast cancer, substitution of docetaxel for paclitaxel event occurred exclusively during paclitaxel drug stockout. Delays of ≥7 days events were most frequent in breast cancer patients receiving paclitaxel during stockout, and combination doxorubicin and cyclophosphamide even during periods of non-stockout.

CONCLUSIONS

The aetiology of suboptimal events differed during stockout and non-stockout periods. Prescription patterns that involved de-escalation of initiated therapy and substitution of paclitaxel with docetaxel occurred frequently during periods of drug stockout. Further research needs to be conducted to understand the impact of stockout on survival and barriers to maintaining essential cancer medicines supplies in SSA, and the factors driving frequent delays in therapy delivery.

Sales of anti-cancer medicines; China, Indonesia, Kazakhstan, Malaysia, Philippines and Thailand

OBJECTIVE

To assess sales of anti-cancer medicines in the 2017 World Health Organization's WHO Model list of essential medicines in China, Indonesia, Kazakhstan, Malaysia, Philippines and Thailand from 2007 (2008 for Kazakhstan and Malaysia) to 2017.

METHODS

We extracted sales volume data for 39 anti-cancer medicines from the IQVIA database. We divided the total quantity sold by the reference defined daily dose to estimate the total number of defined daily doses sold, per country per year, for three types of anti-cancer therapies (traditional chemotherapy, targeted therapy and endocrine therapy). We adjusted these data by the number of new cancer cases in each country for each year.

FINDINGS

We observed an increase in sales across all types of anti-cancer therapies in all countries. The largest number of defined daily doses of traditional chemotherapy per new cancer case was sold in Thailand; however, the largest relative increase per new cancer case occurred in Indonesia (9.48-fold). The largest absolute and relative increases in sales of defined daily doses of targeted therapies per new cancer case occurred in Kazakhstan. Malaysia sold the largest number of adjusted defined daily doses of endocrine therapies in 2017, while China and Indonesia more than doubled their adjusted sales volumes between 2007 and 2017.

CONCLUSION

The use of sales data can fill an important knowledge gap in the use of anti-cancer medicines, particularly during periods of insurance coverage expansion. Combined with other data, sales volume data can help to monitor efforts to improve equitable access to essential medicines.

Availability, prices, and affordability of selected essential cancer medicines in a middle-income country - the case of Mexico

Background

More alternatives have become available for the diagnosis and treatment of cancer in low- and middle-income countries. Because of increasing demands, governments are now facing a problem of limited affordability and availability of essential cancer medicines. Yet, precise information about the access to these medicines is limited, and the methodology is not very well developed. We assessed the availability and affordability of essential cancer medicines in Mexico, and compared their prices against those in other countries of the region.

Methods

We surveyed 21 public hospitals and 19 private pharmacies in 8 states of Mexico. Data were collected on the availability and prices of 49 essential cancer medicines. Prices were compared against those in Chile, Peru, Brazil, Colombia and PAHO’s Strategic Fund.

Results

Of the various medicines, mean availability in public and private sector outlets was 61.2 and 67.5%, respectively. In the public sector, medicines covered by the public health insurance “People’s Health Insurance” were more available. Only seven (public sector) and five (private sector) out of the 49 medicines were considered affordable. Public sector procurement prices were 41% lower than in other countries of the region.

Conclusions

The availability of essential cancer medicines, in the public and private sector, falls below World Health Organization’s 80% target. The affordability remains suboptimal as well. A national health insurance scheme could serve as a mechanism to improve access to cancer medicines in the public sector. Comprehensive pricing policies are warranted to improve the affordability of cancer medicines in the private sector.

Selection of Blood, Blood Components, and Blood Products as Essential Medicines in 105 Low- and Middle-Income Countries

Blood products of human origin are essential treatment options for several diseases, for example, hemophilia. We studied the alignment of national essential medicines lists (NEMLs) of low- and middle-income countries (LMICs) with the World Health Organization (WHO) Model List for the selection of blood products of human origin. The most recent versions of NEMLs from all LMICs were studied for the inclusion of blood products of human origin (blood and blood components, plasma products, and immunoglobulins). Data obtained from 105 NEMLs were compared to the 2017 WHO Model List. The median number of blood products of human origin on the NEMLs was 4 (range: 0-10). Immunoglobulins were most frequently included (73%). Blood and blood components were the least selected products (15%). The uptake of plasma products was around 50%. Nine countries did not have any blood products of human origin on their NEMLs. Some NEMLs included blood products not listed on the WHO Model List (albumin, hepatitis A immunoglobulin, and cryoprecipitate). We observed variation in selection according to WHO region, income level, and year of NEML update. Alignment of NEMLs with the WHO Model List varied greatly for different groups of blood products, ranging from good uptake for immunoglobulins, reasonable uptake for plasma products, to poor uptake for blood and blood components. This heterogeneity in selection and inclusion of blood products of human origin on NEMLs may be partly explained as being due to specific country characteristics, but some of it may not be explained. Policy makers need to rely on evidence in making decisions about which blood products to select, include, and remove on their NEMLs.

Access to innovative cancer medicines in a middle-income country - the case of Mexico

BACKGROUND

Cancer has become the third cause of death in Mexico. Treatment for cancer is often complex and lengthy. New and better medicines enter the market at high prices, which may limit access. Like most Latin American countries, Mexico has an essential cancer medicines list that includes innovative medicines. Their accessibility and use in the public sector remains unknown. Therefore, we describe the use, as a proxy of access, of innovative and essential cancer medicines in the public sector in Mexico, by insurance institution, and by five regions between 2010 to 2016.

METHODS

We used drug utilization research methods to assess the use of eight patented cancer medicines. Through the national transparency platform, we obtained data on the quantities of these medicines used in all public health facilities and social health insurance institutions and recalculated those figures into defined daily dose (DDD) per 1000 population per year.

RESULTS

Overall, the use of all medicines increased over the years, especially for trastuzumab, rituximab and imatinib. The use of innovative medicines was higher per population covered in social health insurance institutions than in governmental facilities. Throughout the study period, the Central region (including Mexico City) has used more medicines per population than the other regions.

CONCLUSIONS

The use and access of some essential innovative cancer medicines has increased over the years, but remains unequal across insurance schemes and regions. Particularly, the Ministry of Health Insurance scheme and Northern and Western regions in the country would benefit from additional efforts to increase access to essential cancer medicines.

Curcumin as an anti-inflammatory agent: Implications to radiotherapy and chemotherapy

Cancer is the second cause of death worldwide. Chemotherapy and radiotherapy are the most common modalities for the treatment of cancer. Experimental studies have shown that inflammation plays a central role in tumor resistance and the incidence of several side effects following both chemotherapy and radiotherapy. Inflammation resulting from radiotherapy and chemotherapy is responsible for adverse events such as dermatitis, mucositis, pneumonitis, fibrosis, and bone marrow toxicity. Chronic inflammation may also lead to the development of second cancer during years after treatment. A number of anti-inflammatory drugs such as nonsteroidal anti-inflammatory agents have been proposed to alleviate chronic inflammatory reactions after radiotherapy or chemotherapy. Curcumin is a well-documented herbal anti-inflammatory agents. Studies have proposed that curcumin can help management of inflammation during and after radiotherapy and chemotherapy. Curcumin targets various inflammatory mediators such as cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor κB (NF-κB), thereby attenuating the release of proinflammatory and profibrotic cytokines, and suppressing chronic production of free radicals, which culminates in the amelioration of tissue toxicity. Through modulation of NF-κB and its downstream signaling cascade, curcumin can also reduce angiogenesis, tumor growth, and metastasis. Low toxicity of curcumin is linked to its cytoprotective effects in normal tissues. This protective action along with the capacity of this phytochemical to sensitize tumor cells to radiotherapy and chemotherapy makes it a potential candidate for use as an adjuvant in cancer therapy. There is also evidence from clinical trials suggesting the potential utility of curcumin for acute inflammatory reactions during radiotherapy such as dermatitis and mucositis.

Building reliable supply chains for noncommunicable disease commodities: lessons learned from HIV and evidence needs

OBJECTIVE

Successful noncommunicable disease (NCD) management requires a reliable supply chain. The objectives of this article are to examine lessons learned from HIV supply chain initiatives, describe opportunities to advance supply chain systems for NCD health commodities based on HIV supply chain successes and identify areas where additional research is still needed for reliable NCD supply chains in LMICs.

DESIGN

We describe practical experiences gained from developing HIV supply chain systems and how those lessons can be used to inform NCD supply chain systems.

METHODS

Supply chain challenges with HIV commodities in low and middle-income countries (LMICs) are identified and categorized using literature review and expert experiences. Solutions are described on the basis of lessons learned from global HIV initiatives. Opportunities to further advance NCD supply chain systems are recommended.

RESULTS

Supply chain challenges can be organized into two groups: 1) resource mobilization and 2) resource utilization. Global HIV initiatives have responded to resource mobilization challenges by increasing availability of funding, filling human resource gaps, improving essential storage and creating better transport mechanisms and information technology infrastructure. These initiatives have assisted in better resource utilization by strengthening procurement processes, standardizing and simplifying supply chain systems, reducing integrity and security vulnerabilities and harnessing the power of better data. Advances achieved through HIV initiatives are readily transferrable to NCD supply chains with minimal additional investment. Research opportunities exist to identify the most efficient and cost-effective ways to develop more reliable supply chains for NCDs.

Barriers and Challenges to Treatment Alternatives for Early-Stage Cervical Cancer in Lower-Resource Settings

Cervical cancer is one of the most common cancers among women worldwide, and approximately 85% of new diagnoses occur in less-developed regions of the world. Global efforts in cervical cancer to date have focused on primary and secondary prevention strategies of human papillomavirus vaccination and cervical cancer screening. Cervical cancer screening is effective to reduce the incidence of cervical cancer and can result in diagnosis at earlier stages, but it will take time to realize its full impact. With expansion of screening programs, there is now a greater imperative to increase access to treatment for women who have cervical cancer, particularly in earlier stages of disease, when it is still curable. Resources for multimodality treatment can be limited-or even absent-in many less-developed regions of the world and may be associated with geographic, social, and financial barriers for the patient. However, there is evidence that, in many cases, less-invasive and less-resource-intensive treatment options are still effective. To this end, the National Comprehensive Cancer Network and American Society of Clinical Oncology have published guideline adaptations for specific resource constraints, and research about more conservative approaches to the treatment of cervical cancer continues. This review focuses on potential barriers and challenges to provision of safe and effective treatment of early-stage cervical cancer in lower-resource settings, and it suggests future directions for expansion of access to cervical cancer treatment around the world.

Essential medicines for cancer: WHO recommendations and national priorities

Objective

To examine, for essential anti-cancer medicines, the alignment of national lists of essential medicines and national reimbursable medicines lists with the World Health Organization’s (WHO’s) Model Lists.

Methods

National medicine lists for 135 countries with per-capita gross national incomes below 25 000 United States dollars in 2015 were compared with WHO’s 2013 and 2015 Model Lists of Essential Medicines. Correlations between numbers of anti-cancer medicines included in national lists and gross national income (GNI), government health expenditure and number of physicians per 1000 population were evaluated.

Findings

Of the 25 anti-cancer medicines on the 2013 Model List and the 16 added via the 2015 revision of the Model List, 0–25 (median: 17) and 0–15 (median: 3) appeared in national lists, respectively. There was considerable variability in these numbers within and between World Bank income groups. Of the 16 new medicines included in the 2015 Model List, for example, 0–10 (median: 1) and 2–15 (median: 10) were included in the national lists of low-income and high-income countries, respectively. The numbers of these new medicines included in national lists were significantly correlated (P ≤ 0.0001) with per-capita GNI (r = 0.45), per-capita annual government health expenditure (r = 0.33) and number of physicians per 1000 population (r = 0.48). Twenty-one countries (16%) included the targeted anti-cancer medicines imatinib, rituximab and trastuzumab in their national lists.

Conclusion

Substantial numbers of anti-cancer medicines are included in national lists of low- and middle-income countries but the availability, affordability, accessibility and administration feasibility of these medicines, at country-level, need assessment.

Access to Cytotoxic Medicines by Children With Cancer: A Focus on Low and Middle Income Countries

BACKGROUND

The Essential Medicines Working Group of the International Society of Pediatric Oncology (SIOP) has proposed a list of antineoplastic drugs that should be available in low and middle income countries.

PROCEDURE

Data were extracted on the listing of 18 essential and 8 ancillary antineoplastic medicines in the national essential medicines lists (NEMLs) or national reimbursable medicines lists (NRMLs) of 135 countries with gross national income (GNI) per capita of less than US $25,000. Correlations between numbers of medicines listed and GNI per capita, annual government health expenditure (AGHE) per capita, and the number of physicians per million people were examined.

RESULTS

Listing of the 18 essential antineoplastic drugs ranged from 27% (thioguanine) to 95% (methotrexate). The median number of medicines listed was 7 (0-18) in low income countries (n = 26) and 14 in lower-middle (n = 42), upper-middle (n = 44), and high income countries (n = 20). For the ancillary eight medicines, the median was one (0-8) across the 135 countries. Correlations with GNI per capita (r = 0.17, P = 0.0266) and physician density (r = 0.25, P = 0.0017) were statistically significant; not so for AGHE per capita (r = 0.00, P = 0.5000).

CONCLUSIONS

There was large variability within income groups in numbers of antineoplastic agents identified as essential in NEMLs and NRMLs. While not a direct measure of availability, listing is an important step, guiding procurement for the public sector. These results focus attention on deficits in NEMLs and NMRLs as a step to improving access to effective antineoplastic medicines for cancers in children in low and middle income countries.

Target prices for mass production of tyrosine kinase inhibitors for global cancer treatment

OBJECTIVE

To calculate sustainable generic prices for 4 tyrosine kinase inhibitors (TKIs).

BACKGROUND

TKIs have proven survival benefits in the treatment of several cancers, including chronic myeloid leukaemia, breast, liver, renal and lung cancer. However, current high prices are a barrier to treatment. Mass production of low-cost generic antiretrovirals has led to over 13 million people being on HIV/AIDS treatment worldwide. This analysis estimates target prices for generic TKIs, assuming similar methods of mass production.

METHODS

Four TKIs with patent expiry dates in the next 5 years were selected for analysis: imatinib, erlotinib, lapatinib and sorafenib. Chemistry, dosing, published data on per-kilogram pricing for commercial transactions of active pharmaceutical ingredient (API), and quotes from manufacturers were used to estimate costs of production. Analysis included costs of excipients, formulation, packaging, shipping and a 50% profit margin. Target prices were compared with current prices. Global numbers of patients eligible for treatment with each TKI were estimated.

RESULTS

API costs per kg were $347-$746 for imatinib, $2470 for erlotinib, $4671 for lapatinib, and $3000 for sorafenib. Basing on annual dose requirements, costs of formulation/packaging and a 50% profit margin, target generic prices per person-year were $128-$216 for imatinib, $240 for erlotinib, $1450 for sorafenib, and $4020 for lapatinib. Over 1 million people would be newly eligible to start treatment with these TKIs annually.

CONCLUSIONS

Mass generic production of several TKIs could achieve treatment prices in the range of $128-$4020 per person-year, versus current US prices of $75161-$139,138. Generic TKIs could allow significant savings and scaling-up of treatment globally, for over 1 million eligible patients.

Increasing Access to Oral Anticancer Medicines in Middle-Income Countries: A Case Study of Private Health Insurance Coverage in Brazil

The World Health Organization estimates that approximately 60% of the world’s new annual cancer cases occur in Asia, Africa, and Central and South America, and that 70% of cancer deaths occur in these regions. Although oral chemotherapy is a promising intervention for cancer treatment, given its high cost, it is usually unavailable in middle-income countries. In 2013, after strong lobbying from civil society, Brazil's Congress passed legislation mandating that all private health insurance companies provide access to oral antineoplastic treatment. The decision to scale up the provision of oral chemotherapy was a watershed event in the regulation of private health insurance in Brazil. Until then, private insurers, which cover 25% of the population, were exempted from the provision of pharmaceutical drugs for home care treatments. This article explores the political process involved in regulating the provision of oral chemotherapy medicines by private health insurers. Elements of this successful advocacy case included investment in strategic communication, specialized knowledge of regulatory policy, and the ability to act via democratic channels of political representation. In turn, the receptiveness of government branches such as the Congress and regulating bodies, as well as the Cancer Awareness Month campaign, opened a window of opportunity. However, prospects for expanded access to such medicines in the public health system are bleak in the short term because of the ongoing political and economic crisis.

Proposing Essential Medicines to Treat Cancer: Methodologies, Processes, and Outcomes

PURPOSE

A great proportion of the world's cancer burden resides in low- and middle-income countries where cancer care infrastructure is often weak or absent. Although treatment of cancer is multidisciplinary, involving surgery, radiation, systemic therapies, pathology, radiology, and other specialties, selection of medicines that have impact and are affordable has been particularly challenging in resource-constrained settings. In 2014, at the invitation of the WHO, the Union for International Cancer Control convened experts to develop an approach to propose essential cancer medicines to be included in the WHO Model Essential Medicines Lists (EML) for Adults and for Children, as well as a resulting new list of cancer medicines.

METHODS

Experts identified 29 cancer types with potential for maximal treatment impact, on the basis of incidence and benefit of systemic therapies. More than 90 oncology experts from all continents drafted and reviewed disease-based documents outlining epidemiology, diagnostic needs, treatment options, and benefits and toxicities.

RESULTS

Briefing documents were created for each disease, along with associated standard treatment regimens, resulting in a list of 52 cancer medicines. A comprehensive application was submitted as a revision to the existing cancer medicines on the WHO Model Lists. In May 2015, the WHO announced the addition of 16 medicines to the Adult EML and nine medicines to the Children's EML.

CONCLUSION

The list of medications proposed, and the ability to link each recommended medicine to specific diseases, should allow public officials to apply resources most effectively in developing and supporting nascent or growing cancer treatment programs.

Essential medicines for breast cancer in low and middle income countries

BACKGROUND

Breast cancer is the most common type of cancer among women worldwide. In low and middle-income countries (LMICs), appropriate selection of medicines on national essential medicines lists (NEMLs) is a first step towards adequate access to treatment. We studied selection of systemic treatments for breast cancer on NEMLs and assessed its alignment with treatment guidelines for different types of early and advanced breast cancer. Furthermore, influence of country characteristics on the selection was investigated.

METHOD

NEMLs from 75 LMICs were studied for inclusion of all components of therapy in each stage of breast cancer according to international consensus guidelines. The results were then grouped by income level, WHO region and the NEMLs' release date. Non parametric tests were used for statistical analysis.

RESULTS

Unlike HER2-targeted therapies (<10%), aromatase inhibitors (12%) and taxanes (28%); tamoxifen and first generation chemotherapeutic regimens (e.g., anthracycline-based regimens) were frequently found in the NEMLs (71-78%). Consequently, all components of treatment for "Luminal A" early breast cancer and non HER2 overexpressed advanced breast cancer were found on the NEMLs of over 70% of countries. However, 40% of the low income countries did not have all the components of therapy for any type of early breast cancer in their NEMLs, and adequate treatment of HER2 overexpressed breast cancer was hardly possible with the current selections. Recent NEMLs were more aligned with the guidelines (p < 0.05). Eastern Mediterranean and African regions less frequently incorporated all components of breast cancer treatment in their NEMLs.

CONCLUSION

Alignment of selection with guidelines' recommendations was inconsistent for different types of early and advanced breast cancer in NEMLs. Regular updates and more attention to clinical guidelines is therefore recommended.

Challenges in managing infections among pediatric cancer patients: Suboptimal national essential medicines lists for low and middle income countries

Infection management for pediatric cancer patients may be compromised in low and middle income countries (LMICs) if key antimicrobials are not included in national essential medicines lists. We screened national essential medicines lists for 81 LMICs, and assessed the frequency and corresponding 95% confidence limits (CL) of countries that included the 15 International Society of Paediatric Oncology-recommended antimicrobial agents. Only 19% (95% CL: 11%, 28%) of countries included all recommended antimicrobials in their national essential medicines lists. The selection of antimicrobial agents for national essential medicines lists in LMICs warrants attention from a pediatric cancer perspective.

Bringing cancer care to the poor: experiences from Rwanda

The knowledge and tools to cure many cancer patients exist in developed countries but are unavailable to many who live in the developing world, resulting in unnecessary loss of life. Bringing cancer care to the poor, particularly to low-income countries, is a great challenge, but it is one that we believe can be met through partnerships, careful planning and a set of guiding principles. Alongside vaccinations, screening and other cancer-prevention efforts, treatment must be a central component of any cancer programme from the start. It is also critical that these programmes include implementation research to determine programmatic efficacy, where gaps in care still exist and where improvements can be made. This article discusses these issues using the example of Rwanda's expanding national cancer programme.
