Summary
Elderly patients with aggressive non-Hodgkin's lymphoma (NHL) may represent a subset with indolent disease. Identifying these patients can help avoid aggressive treatment and reduce associated risks in older adults.
Area of Science:
- Oncology
- Hematology
- Geriatric Medicine
Background:
- Non-Hodgkin's lymphoma (NHL) is a common hematologic malignancy.
- Elderly patients (≥70 years) often face higher risks of treatment-related morbidity and mortality.
- Aggressive chemotherapy regimens may not be suitable for all elderly NHL patients.
Purpose of the Study:
- To investigate the clinical behavior of aggressive non-Hodgkin's lymphoma in elderly patients.
- To identify potential subsets of elderly NHL patients with indolent disease progression.
- To inform treatment strategies and avoid overtreatment in this vulnerable population.
Main Methods:
- Retrospective review of 63 intermediate or high-grade NHL cases over five years.
- Analysis of treatment and outcomes for 19 patients aged 70 years or older.
- Clinical observation of disease behavior in untreated or minimally treated elderly patients.
Main Results:
- Four elderly patients received no or minimal treatment.
- Three of these patients remained disease-free for 1-3 years.
- One patient experienced late, indolent relapse after three years.
Conclusions:
- A subset of elderly patients with histologically aggressive NHL may exhibit indolent disease behavior.
- Clinical identification of this subset is crucial for tailoring treatment.
- Avoiding aggressive chemotherapy in these patients can prevent significant treatment-related complications.

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
318
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...

344
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...

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...

308
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...

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...

Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
