Approximately 1.6 million new cases of cancer are expected to be diagnosed in the United States in 2014. Many patients diagnosed with cancer will eventually require support from a family caregiver. In fact, family caregivers form the foundation of the health care system in the United States, supporting advances in treatment such as multimodality treatment protocols given in outpatient and home settings.
This complementary and alternative medicine (CAM) information summary provides an overview of the use of laetrile as a treatment for people with cancer. The summary includes a history of laetrile research, a review of laboratory studies, the results of clinical trials, and possible side effects of laetrile use.
This summary contains the following key information:
Laetrile is another name for the chemical amygdalin, which is found in the pits of many fruits and in numerous plants.
Also referred to as informal caregivers, family caregivers provide a complex array of support tasks that extend across physical, psychological, spiritual, and emotional domains. Generally speaking, more women than men become caregivers, most caregivers are related to the person who has cancer, and most caregivers are aged 55 years or older.[4,5]
Family caregivers play an important role in the management of cancer; enlisting their cooperation and including them as the unit of care from the outset are considered critical ingredients to effective cancer management. Most oncology teams recognize this and try to include family caregivers in treatment planning, decision making, and implementation. However, for interventions to be feasible, they must be appropriate within the constraints of busy oncology practices and service delivery environments. Short-term hospital admissions may also restrict the time available to implement supportive strategies for caregivers.
Information about the following is included in this summary:
An overview of the caregiver's perspective across the illness trajectory in cancer.
Typical caregiver roles and concerns.
In this summary, unless otherwise stated, evidence and practice issues as they relate to adults are discussed. The evidence and application to practice related to children may differ significantly from information related to adults. When specific information about the care of children is available, it is summarized under its own heading.
