Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

7.2K
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.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Cancer Therapies

10.5K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Tumor Immunotherapy01:27

Tumor Immunotherapy

2.1K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Biological Effects of Radiation02:59

Biological Effects of Radiation

18.6K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Area of Science:

  • Oncology
  • Psychological Medicine
  • Healthcare Management

Background:

  • Cancer patients undergoing radiation therapy experience psychological distress.
  • Coping mechanisms, or defense mechanisms, may influence healthcare utilization.
  • Understanding these relationships can optimize patient care and resource allocation.

Purpose of the Study:

  • To investigate the relationship between defense mechanism utilization, psychological distress, and medical service use in cancer patients.
  • To determine if patient-controlled versus physician-controlled medical services are differentially predicted by psychological factors.

Main Methods:

  • A cohort of 49 cancer patients receiving radiation therapy was assessed.
  • Data collected included defense mechanism use, psychological distress levels, and medical service utilization (outpatient visits, emergency department visits, overnight hospitalizations).
  • Statistical analyses were performed to identify predictors of service utilization.

Main Results:

  • Defense mechanism use significantly predicted requests for extra outpatient visits.
  • Psychological distress was the primary predictor of overnight hospitalizations.
  • Emergency department visits were influenced by both defense mechanisms and psychological distress.
  • An interaction between defense mechanisms and psychological distress predicted hospitalization.

Conclusions:

  • Patient-controlled healthcare service utilization, such as outpatient visits, is linked to psychological coping strategies.
  • Physician-controlled healthcare utilization, like hospitalization, is more closely tied to the severity of psychological distress.
  • Both psychological distress and defense mechanisms play a role in emergency service use, highlighting a complex interplay in cancer patient care.
