[Colorectal cancer in the elderly].
Summary
Elderly patients with colorectal cancer face disadvantages in treatment. A comprehensive geriatric assessment can improve treatment decisions for older adults, enhancing outcomes.
Area of Science:
- Oncology
- Geriatrics
- Public Health
Background:
- Colorectal cancer presents a significant health challenge in the Czech Republic, with a high proportion of patients over 70 years old.
- Current oncological and anesthesiological classifications inadequately assess treatment tolerance in elderly patients.
- The study addresses the need for better evaluation of treatment options for older adults with colorectal cancer.
Purpose of the Study:
- To evaluate the impact of age on the utilization and outcomes of various colorectal cancer treatment modalities.
- To explore alternative methods for assessing therapy tolerance in elderly patients.
- To identify potential improvements in the treatment indication process for older individuals.
Main Methods:
- Retrospective analysis of a five-year dataset from the NOR database.
- Comparison of treatment parameters and outcomes between patients younger and older than 70 years.
- Data sourced from the Institute of Biostatistics and Analyses, Masaryk University.
Main Results:
- Significant differences were observed in all analyzed parameters between patients under and over 70 years of age.
- Older patients (over 70) experienced treatment disadvantages compared to younger counterparts.
- A higher percentage of elderly patients (25.2%) did not receive treatment compared to younger patients (11.2%).
Conclusions:
- A complex geriatric assessment is recommended to optimize treatment indications for elderly colorectal cancer patients.
- Geriatric evaluation can lead to more appropriate and effective treatment strategies, including surgical interventions.
- Implementing geriatric assessments may improve outcomes and reduce undertreatment in the elderly population.

345
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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
311
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...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
314
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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
315
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

799
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...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
330
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
