Summary
This study details building a personalized cancer treatment system using a user-centered approach. The system, supporting tumor chemosensitivity assays, was evaluated using heuristic methods.
Area of Science:
- Oncology
- Human-Computer Interaction
- Health Informatics
Background:
- Personalized cancer treatment aims to tailor therapies to individual patients.
- Tumor chemosensitivity assays are crucial for predicting treatment efficacy.
- Developing health systems requires addressing quality and legal considerations.
Purpose of the Study:
- To describe the user-centered development of a personalized cancer treatment system.
- To detail the application of Contextual Design principles in system construction.
- To evaluate the system's usability and effectiveness.
Main Methods:
- Contextual Design methodology, involving seven steps.
- System implementation details.
- Think-Aloud protocol and Heuristic Evaluation for usability testing.
Main Results:
- Heuristic evaluation revealed one missing heuristic, partial coverage of five, and full coverage of four.
- Qualitative user feedback was incorporated.
- The system was built following a user-centered approach.
Conclusions:
- The user-centered approach, specifically Contextual Design, is effective for developing personalized cancer treatment systems.
- Usability evaluation is critical for health system development.
- Further refinement based on heuristic evaluation is suggested.

6.3K
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...

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.

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

01:27Tumor Immunotherapy
2.1K
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.

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...

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...
