Radiation: Applications

2.0K
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...

Targeted Cancer Therapies

9.1K
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...

Treatment Resistant Cancers

3.9K
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...

Area of Science:

  • Oncology
  • Public Health
  • Health Economics

Background:

  • Radiotherapy is a cornerstone of comprehensive cancer treatment, crucial for both curative and palliative care.
  • Despite its importance, access to radiotherapy services is unacceptably low globally, especially in low- and middle-income countries.
  • Radiotherapy is often the last resource considered in cancer treatment capacity planning.

Purpose of the Study:

  • To quantify worldwide radiotherapy service coverage by country.
  • To identify the shortfall in radiotherapy access from 2015-2035 based on current and projected needs.
  • To demonstrate the health and economic benefits of investing in radiotherapy expansion.

Main Methods:

  • Analysis of global radiotherapy service coverage and needs projections.
  • Economic modeling to estimate costs and benefits of scaling up radiotherapy capacity.
  • Calculation of life-years saved and economic returns under different investment scenarios (nominal and efficiency models).

Main Results:

  • Significant shortfalls in radiotherapy access exist globally, with projected needs increasing from 2015-2035.
  • Scaling up radiotherapy capacity requires substantial investment, estimated at $184.0 billion (nominal) or $96.8 billion (efficiency) in low- and middle-income countries by 2035.
  • Investment yields significant health benefits, potentially saving 26.9 million life-years, and substantial economic returns, ranging from $16.9 billion to $365.4 billion depending on the model.

Conclusions:

  • Investment in radiotherapy is essential for effective cancer treatment and significantly improves patient outcomes.
  • Expanding radiotherapy services offers compelling health and economic advantages, particularly for low- and middle-income countries.
  • The positive returns on investment underscore the critical need to prioritize radiotherapy in global cancer control strategies.
