Number of patients with an accurate awareness of their prognosis

16.5 %; 18.5 % IF the most-important doctor discussed prognosis [47]

Patients with metastatic colon or lung cancer who could identify the usual prognosis as <5 and 2 years, respectively

Accuracy was directly related to the propensity of the doctor to actually discuss prognosis

Number who thought chemotherapy could cure their metastatic disease

69 % of patients with lung cancer and 81 % of those with colorectal cancer

All of these patients had incurable disease

Number who understood that palliative radiation was not going to cure them

Only 36 % of 384 lung cancer patients understood that radiation would not cure them

All of these patients had incurable disease

Number of lung cancer patients who had discussed hospice with any doctor, 2 months before death

Only 53 % had discussed hospice with any provider 2 months before death [48]

Having this discussion 2 months before death decreased the in-hospital death rate from 51 to 19 % [49]

Number of lung and colorectal cancer patients with any documented end-of-life discussion

73 % overall

Most terminally ill cancer patients never discuss their death with their oncologist, even though we know such discussions do not increase anxiety or depression, or take away hope

55 % occurred in the hospital

27 % of the time with oncologists

Most common time was 33 days before death [50]

Prognostic awareness or knowing that one has a terminal cancer

74 % [51]

Patients who die in the hospital have more emotional and physical distress, especially ICU decedents, compared with home hospice [52]

Regret about end-of-life care

At least 50 % experience regret about the EOL care their loved one receives

Completion of advance care planning strongly associated with reduced caregiver distress [53]





Effectiveness of Treatments


First, the good news about enhanced effectiveness is that cancer death rates are falling from a combination of prevention, earlier detection, and treatment, 1.8 % a year for men and 1.4 % a year for women [2]. The main themes are targeted treatments to a specific pathway or ligand, harnessing of the immune system, and combinations of drugs. Table 28.2 lists some of the major advances of the past 10 years and is a harbinger of things to come as we understand both the mechanism of cancer growth, how it escapes immune regulation by masquerading as “self,” and how cancer growth can be modulated.

Comment

Chronic myelogenous leukemia

Imatinib mesylate (Gleevec), followed by other drugs that can circumvent resistance such as nilotunib, dasatinib, and others

Controls the disease in 90 % of more of patients with a daily pill; mechanisms of resistance are well enough described that we can target a second or third drug effectively [54]

Highly effective but costly: the cost of imatinib has risen from $30,000 per year at its introduction in 2001 to $92,000 in 2015 [55], and patient co-pays are reducing compliance [56]

Breast cancer

Trastuzamab [57] (Herceptin), followed by Kadzilla and Perjada

Doubles life-span in metastatic disease with some long-term survivors; doubles the effectiveness of adjuvant treatment (after surgery)

Has met the requirement for cost-effectiveness in most countries

“Lumpectomy” followed by radiation therapy to remaining breast

Equal or better cure rates than surgery, less surgery, and disfigurement

Initial resistance by surgeons, with demand driven by patients and by specialized breast cancers offering the treatment

Genetic testing [58], including BRCA 1 and 2

Most mutations allows for more genetic change in the breast DNA, which eventually allows cancer-causing mutations. Accounts for ~5 % of breast cancer cases

Has not changed treatment, but if a mutation is found, the risk of second breast cancer or ovary cancer is much higher. Affected relatives can elect prophylactic mastectomy and oophorectomy or chemoprevention with tamoxifen

Lung cancer

Helical Computerized Tomography screening in patients at high risk of lung cancer reduces the risk of death by 7 %, and the risk of lung cancer death by 20 % [59]

Useful in patients at high risk of lung cancer due to smoking, family history, etc.

Controversial because it identifies so many other non-cancer entities, with attendant complications and costs due to need to biopsy them all. The cost-effectiveness is about $240,000 to save one life from lung cancer [60]

Targeted agents against Epidermal Growth Factor Receptor (EGFR), anaplastic lymphoma kinase (ALK) [61] that inhibit the cancer cells more than normal cells

Anti-ALK drugs induce remission and disease control in 60–75 % of patients, lasting on average 6 months; EGFR drugs induce responses in 50 %

At present, all cancers develop resistance, usually in 6–12 months, so the impact on survival has been small. The drugs cost $6000–13,000 a month

Unleashing the immune system to target lung cancer by using antibodies or small molecules to block Programmed Death (PD) 1 or PD Ligand 1 (PDL) pathways. These pathways are used by the cancer to hide from the immune system [62]

About 1 in 4 patients have a dramatic response to PD-1 therapy, often lasting years

The drugs cost $13,000 or more a month and can cause unusual autoimmune side effects such as pneumonitis, colitis, and pituitary failure

Acute or chronic lymphocytic leukemia refractory to usual treatments

Treatment harvests T cells by extraction from the blood, uses a disabled virus vector to carry the CD-19 gene into the T-cells, so the T-cells attack and kill any cell bearing CD 19

Highly effective in adult chronic lymphocytic leukemia and pediatric acute lymphocytic leukemia patients, inducing durable remissions in over 75 % [63]

Still not widely available but will soon be available

As the technology advances, available for more cancers including epithelial cancers [64]

The bad news is the cost of cancer care in both the United States and Canada, and for those who have access to state-of-the-art care in Mexico, is escalating. Drugs make up about 10 % of the cancer care budget but are increasing in price. The most recent small molecules or antibodies to cancer cost over $13,000 a month, not including imaging such as PET or MRI scans, and lab tests. The best predictor for the cost of the new drug is the price of the last five drugs that came to market before it, rather than the effectiveness or originality of the new drug [3]. The drug companies that make the new drugs state that the cost of clinical trials is extraordinarily high and that the targeted drugs have a smaller market (for instance, only 1–3 % of lung cancers are anaplastic lymphoma kinase (ALK)-positive for an ALK-targeted drug.). Critics of the high prices point out that the costs of designing new drugs may be substantially less with techniques like X-ray crystallography allowing for easier design that can be used for multiple drugs; the much smaller trials in selected groups of patients with the target; that drug companies are still highly profitable; and that the best predictor of price is not efficacy but the price of the last drug to come to market [4]. With no transparency in the process, this argument will be unresolved for the immediate future. These issues are in all high-income countries, not just the United States and Canada.

There is no good solution to this crisis of high prices, although all parties agree that it needs be fixed [5]. There has been some recent progress in negotiating lower prices by large insurance companies forcing manufacturers to compete when there are alternative drugs, such as the new antivirals for hepatitis C [6]. The successful bidding has decreased the price to that paid in Europe, about one-third less. However, not all situations have competing drugs, especially with novel cancer treatments, and when insurance companies refuse to cover a drug it leads to calls of “rationing” and “death panels” in the United States. In Canada, the coverage of new drugs varies considerably from province to province, but with a mostly one-payer system, there appears to be more buy-in for a communal process. Most drugs approved by the provincial authorities for efficacy have made it belatedly, if at all, to the budget. In the United Kingdom, there have been multiple disapprovals of new drugs based on formal cost-effectiveness, with much public disapproval but not real recourse given a set budget.

Drugs make up only about 10 % of the total cancer budget; the most expensive part of treatment remains hospitalization [7]. This is where palliative care and hospice have become increasingly important as models of concurrent palliative care along with usual oncology care show improved symptoms, better quality of life, equal or longer survival [8], and lower cost in nearly all trials [9]. As shown in Table 28.3, palliative care has multiple opportunities to reduce the cost of care by at least 10 %, thus saving a substantial amount of money for advances in cancer treatment [10]. These include, but are not limited to—in addition to better care—prevented hospitalizations, lower cost per day if hospitalized, shorter length of stay, and reduced readmission rates.

Ways in which palliative care can improve care while reducing the cost of care












































Mechanism

Study

Savings

Prevent hospitalizations from symptoms, which account for 60 % of cancer admissions [65]

Non-randomized

$$$

U Wisconsin academic center; 64 % of admissions were due to symptoms and potentially preventable

Allow hospice transition sooner by introducing concurrent care

Non-randomized

Hospitalizations were reduced from 15 days to 2 per member; ICU days 10 down to 1 per member; doubling of use of hospice and length of stay [66]. Overall savings 22 % in the last 40 days of life [67]

Aetna provided enhanced hospice with concurrent care, introducing the hospice team sooner

Now being tested by Medicare in the United States

Concurrent interdisciplinary inpatient palliative care team (IPCT) for patients with less than 1 year to live patients

517 Patient randomized trial

Approximately equal survival; markedly better satisfaction; half the rate of ICU use (12 versus 21, p = 0.04). Costs were $4900 less even including the cost of the IPCT [68]

Concurrent interdisciplinary palliative care for homebound terminally ill patients

Randomized trial of 298 patients, homebound, to usual care versus usual care and IDPCT

Approximately equal survival; almost $8000 savings per person [69]

Recognition of hospice-eligible patients, with enrollment if eligible

U Iowa academic center. 229 decedents identified; 60 % of decedents were eligible for hospice on the penultimate admission, based on National Hospice and Palliative Care Organization (NHPCO) criteria [70]

Only 14 % had any discussion of hospice, despite being eligible; 14 of 17 enrolled, all from ONE service. If they enrolled in hospice the chance of dying in the hospital was 7/14 (50 %) at a cost of $5000. If they were not offered hospice, 202/209 died in the hospital at a median cost of $52,000 [71]

Reducing readmission rates and costs

Non-randomized but carefully controlled study

If patients were seen by the inpatient palliative care team and sent home with hospice or palliative care, the readmission rate in 30 days was ~5 %; if not, about 25 % [72]

Not restricted to palliative care: Acute Care for Elders programs have similar savings and reduced readmissions [73]

These difficulties are not unique to the United States. Canada’s system has been called “a system in name only” with marked variation in available services [11]. Only half of drug costs are paid by the provinces; the rest by individuals. About 30 % of total health care costs are borne by individuals. There are substantial variations in cancer drug availability even after the drugs have been approved by the federal and provincial governments [12]. The same congestive heart failure patient in different provinces could spend $74–$1332 for $1200 worth of medicines [13]. Canada doubled real-value spending on health care in the last decade but remains tenth of 11 industrialized countries in a respected review by The Commonwealth Fund [14] suggesting that more fundamental reforms in the provision of care will be needed in the future.


Innovations


In all countries, innovations in evidence-based guidelines or practice pathways continue to lead the way to better care and lower costs. A private US firm, US Oncology that provides 15 % of the care to all US cancer patients, has provided the best examples. Using doctor-approved pathways, they have maintained or improved survival in metastatic lung [15] and colorectal [16] cancer patients while reducing the total cost by 35 %. By added nurse phone calls to patients after chemotherapy (“troubleshooting”), they were able to further reduce ER visits and costs [17]. Adding a fixed reimbursement model (the oncologist got paid the same no matter what drugs she prescribed, and got paid more for following an evidence-based guideline) reduced the total cost of care by almost one-third [18], from an expected $98,121,388 for 810 patients in five practices to an actual cost of $64,760,116. Surprisingly, drug costs were triple than expected but the total cost savings to the insurer were still nearly one-third.


Interrelationship Between Cancer Care and Local Culture


In all countries , there are persistent `disparities in care due to race, socioeconomic status, and location. For instance, colorectal cancer screening has been under-utilized by African-Americans for decades. The state of Delaware reduced the disparities by making colonoscopy available in patient communities by raising the reimbursement, giving coupons for free colonoscopy, public outreach especially to faith communities, education, and ensuring completion with patient navigators [19, 20]. Whether this can be replicated in larger more diverse states remains to be seen, but it is an encouraging step. Other disparities are a mix of biologic and socioeconomic circumstances. For example, African American women have the highest rates of triple negative breast cancer (negative for estrogen, progesterone, and HER-2 targets) with a rate of 28 % of all cancers, compared to 12 % for age-matched white women [21, 22]. Current evidence suggest that improvements in the care provided can reduce many of these disparities, such as more federally financed health centers to provide screening in low-income areas [23], and patient navigation [24].


Insights on Palliative Care in Cancer Patients



Palliative Care in North America


Modern palliative care and hospice programs trace their origins to the work of Dame Cicely Saunders at St. Christopher’s Hospice in London in the late 1960s. Earlier use of the term “hospice” reference (usually religious) homes for the dying—a tradition that reaches far back into the Middle Ages—that did not offer the evidence-based, multidisciplinary approach to suffering and death that characterizes the modern use of the word.

While the countries of North America (Mexico, the United States, and Canada) share a continent and certain cultural and ecologic characteristics (especially in border regions) their health care systems and, hence, their palliative care and hospice programs, have evolved in different ways and with different paces. Comparisons of palliative care between countries is made difficult by several methodological factors including the lack of a theoretical background, lack of information on use of experts as sources of information, use of grey literature, problematic international rankings, and difficulties associated with the nature of data on palliative care provision [25]. In this chapter, we will, therefore, simply describe key aspects of palliative and hospice care in the three countries noting important policy and institutional developments.


Mexico


Health in Mexico is defined as a social right and guarantee in Article IV of the Federal Constitution [26]. Stemming from this, on November 25, 2008 the Senate of the Republic voted in reforms to the General Health Law that were implemented in January 2009 with publication in the Official Federal Gazette. These reforms included the right of Mexicans with a terminal disease to be treated with palliative care [27].

A report entitled “Care When There is No Cure: ensuring the right to Palliative Care in Mexico” by the Non-Governmental Group Human Rights Watch and published in October 2014 found however “…that currently only a few dozen public healthcare institutions in the country offer palliative care and even fewer provide it in patients’ homes. Most healthcare personnel have received no training in the discipline, and few doctors are licensed to prescribe strong pain medicines that are essential for palliative care. Where palliative care is available it is often due to the efforts of individual physicians or advocates rather than the result of a deliberate policy of the government, health system or insurer” [28]. Human Rights Watch identified a number of specific issues that have made access to palliative care challenging in Mexico. These include lack of availability of opioid analgesics, lack of training of health professionals in palliative care, cumbersome regulations governing opioid prescribing, and overall health resource limitations.

The International Association for Hospice and Palliative Care’s Global Directory of Programs and Services identifies 20 palliative care programs in Mexico [29]. These include community-based organizations, academic and hospital-based initiatives. Considering that the World Health Organization Cancer Country Profiles (2014) [30] estimate an annual total of 605,000 deaths (71,900 from cancer) in Mexico, it is clear that there is a substantial unmet need for palliative services.

An important step to meet this need was recently made by the Mexican Ministry of Health in December 2014 when it issued national palliative care guidelines that outline criteria and methods for initiating palliative care and which emphasize the importance of providing palliative care in home settings. Additionally, other reforms related to prescribing analgesics and professional education were announced [31].


Canada


The Canadian Hospice and Palliative Care Association (CHPCA) traces the origins of palliative and hospice care in Canada to the near simultaneous opening in 1975 of palliative care units at St. Boniface General Hospital in Winnipeg, Manitoba, and The Royal Victoria Hospital in Montreal, PQ [32]. A cancer surgeon, Dr. Balfour Mount, led the development of the latter facility. He had occasion to visit St. Christopher’s hospice in London and was inspired to create a hospital-based set of similar services for his cancer patients in Montreal. Additionally, he is credited with the first use of the term “palliative” to describe these services as an alternative to the word “hospice” which had already occupied a place in French lexicon [33]. The first research and educational institute for palliative care was created at the University of Ottawa in 1983 [32].

Today, the CHPCA’s 2012 directory of programs lists 525 hospice palliative care programs in the country [34]. There organizations are represented at both provincial and national levels through voluntary associations that encourage public policy, nongovernmental and educational initiatives to support hospice palliative care. Significant milestones/achievements include:



  • 1983: publication of by Health and Welfare Canada of “Palliative Care Services Guidelines”


  • 1994: incorporation of the Canadian Palliative Care Association


  • 1995: publication of report by the Canadian Senate “Of Life and Death” that examined legal, social, and ethical issues surrounding euthanasia and assisted suicide [35]


  • 2000: publication of “Quality End of Life Care: The Right of Every Canadian” by the Standing Senate Committee on Social Affairs, Science and Technology. This report followed on the 1995 report and made 14 key recommendations intended to advance hospice and palliative care in Canada1 [36]


  • 2002 and 2013: publication and revision of “A Model to Guide Hospice and Palliative Care: based on National Principles and Norms of Practice” [37]


  • 2013: The Royal College of Physicians and Surgeons recognize Palliative Care as a subspecialty of medicine


The United States


Like Canada, early palliative care interest in the United States was inspired by the work of Dame Saunders at St. Christopher’s and the writings of Elisabeth Kubler-Ross. A nurse, Florence Wald, founded what is generally recognized as the first hospice palliative care institution in the United States—Connecticut Hospice—in Branford, CT in 1974. Since then, the number of facilities that provide hospice and palliative care has increased dramatically: The National Hospice and Palliative Care Organization estimates that in 2013 there were approximately 5800 hospices operating in the 50 states, the US Virgin Islands, Puerto Rico, the District of Columbia and Guam [38]. The Center to Advance Palliative Care estimated that between 2002 and 2012 the number of hospital-based palliative care programs in the United States increased 148 % to more than 1600 [39], and the US Accreditation Council for Graduate Medical Education (ACGME) now lists 109 programs for physician fellowship training in hospice and palliative medicine [40].
