Cancer Survival Analysis01:21

Cancer Survival Analysis

455
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
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 Therapies

7.9K
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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

660
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.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.1K
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...

Area of Science:

  • Oncology
  • Radiation Oncology
  • Medical Physics

Background:

  • Anal cancer, though rare, has a rising incidence.
  • Standard treatment involves chemoradiotherapy for non-metastatic disease.
  • Intensity-modulated radiotherapy has improved treatment safety.

Purpose of the Study:

  • To review the role of adaptive radiotherapy (ART) in modern anal cancer care.
  • To discuss the principles, technical workflows, and application of ART.
  • To examine the clinical evidence, including dosimetric and outcome data, for ART in anal cancer.

Main Methods:

  • Overview of ART principles and technical workflows (CT- and MR-guided).
  • Examination of ART application in treatment planning and delivery.
  • Review of existing clinical evidence, dosimetric studies, and clinical trial data.

Main Results:

  • ART addresses significant anatomic and tumor changes during chemoradiotherapy.
  • Potential for enhanced treatment precision and individualized therapy.
  • Emerging data suggests impact on outcomes and toxicity.

Conclusions:

  • Adaptive radiotherapy is a promising strategy for optimizing anal cancer treatment.
  • Further clinical data is needed to fully establish its benefits.
  • ART has the potential to improve treatment efficacy and patient safety in anal cancer management.
