[Pathologic characteristics of malignant neoplasms occurring in the elderly]
Nihon Rinsho. Japanese Journal of Clinical Medicine
|August 19, 2015
Summary
Elderly individuals are more prone to developing cancers like gastric and lung cancer. Specific treatment strategies are needed for elderly cancer patients due to age-related changes affecting tumor behavior and host immunity.
Area of Science:
- Geriatric Oncology
- Cancer Biology
- Immunology
Context:
- Malignant neoplasms disproportionately affect the elderly population.
- Common cancers in older adults include gastric, colorectal, lung, prostate (men), and pancreatic (women).
- Aging is associated with an increased incidence of multiple primary cancers.
Purpose:
- To highlight the unique characteristics of malignant neoplasms in the elderly.
- To discuss age-related host alterations influencing cancer progression.
- To emphasize the need for tailored treatment strategies in geriatric oncology.
Summary:
- Elderly cancers exhibit distinct features in tumor location, histology, biological behavior, and carcinogenesis pathways.
- Contrary to common belief, elderly tumors do not always present with well-differentiation, slow growth, or low metastasis.
- Host factors, including weakened stroma and diminished immune response, significantly impact cancer behavior in older adults.
Impact:
- Recognizing specific geriatric cancer characteristics is crucial for effective management.
- Understanding age-related host changes informs personalized treatment approaches.
- Development of specialized treatment protocols for elderly cancer patients is essential for improved outcomes.

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...

01:19The Effect of Aging on Tissues
4.1K
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...

02:53Adaptive Mechanisms in Cancer Cells
7.4K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.

01:15Drug Dosing: Geriatric Patients
357
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...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
321
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
