Insights

Eliminating cancer metastases is difficult. This study proposes classifying metastases by their biological virulence to improve cancer staging and treatment, moving beyond the idea of widespread disease.

Area of Science:

  • Oncology
  • Cancer Metastasis Research

Background:

  • Eliminating metastases is a significant challenge in curative cancer treatment.
  • Systemic therapies for metastatic cancer prolong survival but rarely offer cures.
  • The traditional view of metastasis as a disseminated process is being challenged.

Purpose of the Study:

  • To present evidence supporting a new hypothesis on cancer metastasis.
  • To propose an integrated approach for classifying metastases.
  • To demonstrate how metastasis classification influences cancer staging and treatment.

Main Methods:

  • Review of existing evidence on metastasis.
  • Development of a hypothesis integrating clinical and molecular data.
  • Analysis of the spectrum of biological virulence in metastatic lesions.

Main Results:

  • Evidence supports the hypothesis that metastases exist on a spectrum of biological virulence.
  • Integrated classification of metastases can refine understanding of metastatic disease.
  • This approach offers a new perspective on cancer staging.

Conclusions:

  • The oligometastatic paradigm offers a more nuanced view of cancer spread.
  • Integrated clinical and molecular classification of metastases is crucial.
  • This approach has the potential to significantly influence cancer treatment strategies.

Polymers: Defining Molecular Weight

Unlike small molecules with definite molecular weights, polymers are a mixture of individual polymer chains of varying lengths, each with a unique molecular weight.  So, the molecular weight of a polymer is expressed as an average value based on the average size of the polymer chains. The two most common forms of averages used for polymers are the number average molecular weight and weight average molecular weight.
The number average molecular weight (Mn) is the summation of the number...

The Electromagnetic Spectrum

The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

The Electromagnetic Spectrum

Electromagnetic waves are categorized according to their wavelengths and frequencies, giving the electromagnetic spectrum. These waves are classified as radio, infrared, ultraviolet, etc. Radio waves refer to electromagnetic radiation with wavelengths ranging from millimeters to kilometers. Radio waves are commonly used for audio communications (i.e., radios) and typically result from an alternating current in the wires of a broadcast antenna. They cover a broad wavelength range and are used...

IR Spectrum01:19

IR Spectrum

When infrared (IR) radiation passes through a molecule, the bonds stretch or bend by absorbing the radiation. This absorption creates the molecule's absorption spectrum, which is the plot of its percentage transmittance versus wavenumber.
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...

Mass Spectrum01:23

Mass Spectrum

A mass spectrum is the graphical representation of the relative abundance of the charged fragments in an analyte plotted against their mass-to-charge ratio (m/z). The plot's x-axis represents the ratio of the mass of the charged fragment to the number of charges it carries. The y axis of the plot represents the relative abundance of each charged species. The relative abundance is calculated from the signal intensity of each charged species recorded at the detector. The most intense signal (the...

UV–Vis Spectrum01:30

UV–Vis Spectrum

When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.     
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...
