Summary
Reduced chemotherapy protocols may improve survival in advanced cancer by leveraging competition between resistant and sensitive cells. Early palliative treatment can accelerate resistance, reducing survival duration.
Area of Science:
- Oncology
- Mathematical Biology
- Pharmacology
Background:
- Palliative cancer chemotherapy aims to extend survival and enhance quality of life when cure is not possible.
- Tumour growth dynamics and drug resistance are critical factors in chemotherapy effectiveness.
Purpose of the Study:
- To analyze chemotherapy protocol design for advanced cancer using a Gompertzian tumour growth model.
- To investigate the impact of drug resistance on palliative chemotherapy outcomes and patient survival.
Main Methods:
- Utilized a simplified, robust mathematical model of advanced tumour growth incorporating Gompertzian dynamics.
- Simulated chemotherapy protocols, considering the effects of developing drug resistance.
- Analyzed the influence of reduced chemotherapy frequency and early palliative interventions.
Main Results:
- Reduced chemotherapy frequency predicted to improve survival by exploiting competition between resistant and sensitive tumour cells.
- Very early palliative chemotherapy suggested to rapidly induce tumour-wide resistance, diminishing survival benefits.
- Simulations indicated that escalated curative attempts (dose densification) can negatively impact survival.
Conclusions:
- Chemotherapy protocol optimization is crucial for maximizing survival in palliative settings.
- Strategic timing and intensity of chemotherapy can influence the development of drug resistance.
- Mathematical modeling provides valuable insights into complex tumour-drug interactions for improved treatment strategies.

02:56Treatment Resistant Cancers
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...

02:50Combination 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...

02:57Targeted Cancer Therapies
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 specific...

02:49Cancer Therapies
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...

01:21Cancer Survival Analysis
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...
