Skin Cancer01:30

Skin Cancer

5.7K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Cancer Therapies

9.8K
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...

Mutations01:35

Mutations

42.7K
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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

1.7K
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.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.6K
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...

Cancer Vaccines01:30

Cancer Vaccines

952
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Area of Science:

  • Radiation oncology and medical physics.
  • Dermatology and cancer research.

Background:

  • Radiation therapy has seen significant advancements in radiobiology and external beam delivery over 40 years.
  • These technical improvements have enhanced dosimetry, leading to more precise targeting and normal tissue sparing.
  • The full impact of these radiotherapy advancements remains underappreciated outside radiation oncology.

Purpose of the Study:

  • To review major radiotherapy advancements relevant to skin cancer management for non-radiation oncologists.
  • To discuss the evidence supporting current and emerging applications of radiotherapy in skin cancer.
  • To re-appraise the role of modern radiotherapy in the comprehensive management of skin cancers.

Main Methods:

  • Review of scientific literature on radiation therapy techniques and outcomes in skin cancer.
  • Analysis of dosimetry improvements, including homogeneity and conformality of photon irradiation.
  • Examination of specialized techniques and emerging applications, such as extended field techniques and immunotherapy combinations.

Main Results:

  • Improved dosimetry allows for more even targeting of planned tissue volumes and better sparing of surrounding normal tissues.
  • Modern radiotherapy techniques offer improved efficacy and safety, making them suitable for high-risk, extensive, or recurrent skin cancers.
  • Emerging applications include extended radiation fields for micrometastatic disease and harnessing radiotherapy's immune-stimulatory potential.

Conclusions:

  • Significant advancements in radiation therapy have enhanced its precision, efficacy, and safety for skin cancer treatment.
  • Modern radiotherapy is increasingly valuable for managing complex skin cancer cases and holds promise in combination with other therapies.
  • A broader understanding and re-appraisal of radiotherapy's role are needed across the spectrum of skin cancer management.
