Cancer Survival Analysis

Cancer 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...

Cancer Therapies

Cancer 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...

Mouse Models of Cancer Study

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Combination Therapies and Personalized Medicine

Combination 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...

Area of Science:

Digital Health
Oncology
Mobile Health Applications

Background:

Cancer treatment, particularly chemotherapy, presents challenges with managing side effects.
Effective communication between cancer patients and healthcare providers is crucial for early detection and management of treatment side effects.
Mobile health (mHealth) applications offer a potential solution to bridge communication gaps and improve patient outcomes.

Purpose of the Study:

To design a cancer-focused mobile health app (CONTIGO) integrating educational content and real-time symptom reporting for chemotherapy patients.
To validate and evaluate the quality of the CONTIGO app using the Mobile App Rating Scale (MARS).
To enhance healthcare communication, reduce hospital readmissions, and optimize symptom management for cancer patients.

Main Methods:

A mixed-methods approach was employed for the development and validation of the mHealth app.
The CONTIGO app was designed using agile methodologies by a multidisciplinary team of healthcare professionals and software engineers.
App quality was assessed by 13 evaluators using the MARS, alongside technical performance analysis.

Main Results:

The CONTIGO app demonstrated strong functionality (4.35/5) and excellent visual stability.
Overall MARS score was 3.75/5, indicating consistent quality, though user engagement scored lower (3.31/5).
Evaluators identified areas for improvement including customization, onboarding, and navigation, while acknowledging the app's potential benefits.

Conclusions:

The CONTIGO app shows promise in functionality, usability, and information quality for oncology care.
Further development is needed to enhance user interactivity and engagement.
Future iterations will incorporate patient feedback to refine the app and improve the overall cancer care experience.
