Summary
Elderly cancer patients often present with unique tumor characteristics and behaviors compared to younger individuals. Age-related host factors significantly influence malignant tumor development and progression in older adults.
Area of Science:
- Geriatric Oncology
- Cancer Biology
- Tumor Carcinogenesis
Context:
- Malignant neoplasms are more prevalent in the elderly population.
- Common cancers in elderly men include gastric, lung, colorectal, and prostate; in women, they are colorectal, gastric, lung, and biliary.
- The incidence of multiple cancers rises with age.
Purpose:
- To highlight the distinct features of neoplasms in the elderly compared to younger patients.
- To discuss the characteristic differences in tumor location, histology, biological behavior, and carcinogenesis pathways.
- To consider age-related host alterations in the context of tumor biology.
Summary:
- Neoplasms in the elderly exhibit unique characteristics, including variations in tumor location, histology, and biological behavior.
- While often characterized as well-differentiated with slow growth, elderly tumors can display aggressive features.
- Host-related factors, such as weakened stroma and diminished immune response, play a crucial role in cancer progression in older adults.
Impact:
- Provides insights into the specific challenges and considerations for treating cancer in elderly patients.
- Emphasizes the need to account for age-related physiological changes when assessing tumor behavior and prognosis.
- Contributes to a better understanding of geriatric oncology and personalized cancer care strategies.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
