What is the primary reason cancer has proven difficult to cure universally, according to the content?
What is the primary reason cancer has proven difficult to cure universally, according to the content?
- Each person's cancer is based on their particular genes, making it unique. (correct)
- Cancer cells rapidly develop resistance to existing treatments, necessitating frequent changes in therapeutic approaches.
- Effective treatments are available, but they are prohibitively expensive, limiting access for many patients.
- Cancer cells are adept at evading detection by the immune system, requiring therapies that can enhance immune recognition.
How did Dr. Wu's observation of bone marrow transplants in leukemia patients influence her approach to cancer research?
How did Dr. Wu's observation of bone marrow transplants in leukemia patients influence her approach to cancer research?
- It led her to explore the use of chemotherapy combinations to maximize cancer cell death.
- It inspired her to investigate methods of directly targeting cancer cells with engineered viruses.
- It highlighted the importance of identifying genetic mutations that drive cancer progression.
- It demonstrated the potential of mobilizing the immune system to fight cancer, inspiring her to create personalized vaccines. (correct)
In Dr. Wu's initial study, what was the key characteristic of the vaccines administered to patients with advanced melanoma?
In Dr. Wu's initial study, what was the key characteristic of the vaccines administered to patients with advanced melanoma?
- They were designed to induce a broad inflammatory response to eradicate cancer cells indiscriminately.
- They contained a standardized formulation of common tumor-associated antigens to stimulate a general immune response.
- They were tailored to each patient, containing their unique cancer proteins to train the immune system to specifically target their cancer cells. (correct)
- They included immune checkpoint inhibitors to block mechanisms that cancer cells use to evade immune detection.

Study Notes
- Dr. Catherine Wu and her team at the Dana-Farber Cancer Institute in Boston are developing custom vaccines to fight each person's unique cancer.
- Wu's research focuses on using the body's immune system to fight cancer cells, inspired by observing how bone marrow transplants helped leukemia patients reset their immune systems.
- The researcher wondered if vaccines created using an individual's cancer characteristics could stimulate their immune system to attack the diseased cells more effectively.
- The custom vaccines boost the body's immune system to fight cancers.
First Study
- Dr. Wu and her team chose six people suffering from advanced melanoma for their first study.
- Scientists analyzed each individual's cancer characteristics and created personalized vaccines containing each patient's unique proteins.
- The vaccines were designed to train the patients' immune systems to recognize and kill cancer cells while sparing the healthy ones.
- In 2015, all individuals were given a seven-shot course of their personalized vaccines.
- By 2017, four patients showed no signs of cancer recurrence.
- The tumors did return for the two patients with the most advanced cancer, but the growths disappeared after the patients received four more doses of the customized vaccines.
- By 2021, all six patients were declared cancer-free.
Awards
- Dr. Wu's research has proved that personalized vaccines can effectively battle cancer.
- In February 2024, she received the prestigious Sjöberg Prize: The honor carries a prize of $1 million — $100,000 as award money and $900,000 to fund future cancer research.
