Flashcards

What is cancer and why is it difficult to find a cure?

Cancer is a disease caused by abnormal cell growth. It can be caused by different factors, and each person's cancer is unique due to their individual genetic makeup.

What is the main focus of Dr. Wu's research?

Dr. Catherine Wu's research focuses on using the body's immune system to fight cancer. The immune system is the body's defense system, and Dr. Wu's work aims to train it to recognize and destroy cancer cells.

What are personalized vaccines and how do they work?

Personalized vaccines are tailor-made for each individual's unique cancer. They are created by analyzing the specific proteins of a person's cancer cells. The vaccines are designed to teach the immune system to attack only the cancer cells, leaving healthy cells untouched.

What type of cancer did Dr. Wu's team initially focus on?

Dr. Wu and her team conducted a study using personalized vaccines on patients with melanoma, a type of skin cancer. They analyzed each patient's cancer cells and created tailored vaccines to train their immune systems.

Study Notes

Personalized Cancer Vaccines

  • Scientists are developing custom cancer vaccines tailored to each patient's unique genetic cancer profile
  • This approach is a departure from traditional, one-size-fits-all cancer treatments.

Dr. Wu's Research

  • Dr. Wu and her team at Dana-Farber Cancer Institute aim to use personalized vaccines to activate the body's immune system against cancer cells.
  • The idea originated from observing that bone marrow transplants can reset the immune system to combat leukemia.
  • Scientists believe that vaccines created using individual cancer characteristics can train the immune system to identify and destroy these cells precisely.

Initial Study Methodology

  • The initial study involved six patients with advanced melanoma.
  • Detailed analysis of individual cancer profiles was conducted.
  • Personalized vaccines containing unique cancer proteins were developed for each patient.
  • These vaccines were designed to target cancer cells, leaving healthy cells unharmed.

Study Results

  • In 2015, all six patients received a seven-shot course of personalized vaccines.
  • By 2017, four of the six patients showed no recurrence of cancer.
  • The two patients with more advanced tumors experienced cancer return but it disappeared after receiving four more vaccine doses.
  • By 2021, all six patients were cancer-free.

Significance and Recognition

  • The small study demonstrated the potential of personalized vaccines in effectively treating cancer.
  • Dr. Wu's research earned her the prestigious Sjöberg Prize in February 2024, worth $1 million.
  • The award includes funding for future cancer research projects.
