Insights

Vascular disrupting agents (VDAs) show moderate tumor growth delay alone. Combining VDAs with chemotherapy or radiotherapy may enhance cancer treatment efficacy, though clinical trials are limited.

Area of Science:

  • Oncology
  • Pharmacology
  • Tumor Biology

Background:

  • Vascular disrupting agents (VDAs) target tumor vasculature, causing blood flow shutdown and necrosis.
  • First-generation VDAs are in clinical trials; new molecules aim to improve efficacy and overcome resistance.
  • VDAs as single agents provide only moderate tumor growth delay.

Purpose of the Study:

  • To investigate the potential of combining VDAs with conventional cancer treatments.
  • To explore the synergy between VDAs and chemotherapy.
  • To evaluate the combination of VDAs with radiotherapy for improved antitumor effects.

Main Methods:

  • Review of existing preclinical studies on VDA combinations.
  • Analysis of ongoing clinical trials involving VDAs.
  • Literature search for evidence supporting VDA and radiotherapy synergy.

Main Results:

  • Preclinical studies suggest VDA combination with chemotherapy enhances efficacy.
  • Numerous preclinical studies indicate VDA and radiotherapy association improves antitumor treatment and therapeutic gain.
  • Limited clinical trials currently exist for VDA and radiotherapy combinations.

Conclusions:

  • Combining VDAs with conventional therapies like chemotherapy and radiotherapy holds significant promise for improved cancer treatment.
  • Further clinical trials are warranted to validate the therapeutic benefits of VDA combinations, particularly with radiotherapy.
  • The development of novel VDAs and combination strategies is crucial for overcoming treatment resistance and enhancing patient outcomes.

Biological Effects of Radiation02:59

Biological Effects of Radiation

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 produce ions...

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Radiation: Applications01:17

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Methods of Sterilization I: Physical Methods

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.
