Our guest today is Dr. Christopher Logothetis, one of the nation’s foremost experts on prostate cancer. Chris has spent nearly five decades at MD Anderson in Houston developing therapies for prostate cancer as well as conducting research into the underlying biology of the disease.
Aside from skin cancers, prostate cancer is the most common cancer among men, claiming a man’s life every 15 minutes in the United States, according to the Prostrate Cancer Foundation. Since the 1970s when Chris joined the staff at MD Andersen, which is the nation’s top-ranked hospital for cancer care, he has been dedicated to the treatment, research, and prevention of genitourinary cancers such bladder, kidney, testes and penis cancer. For the past 25 years, he has focused primarily on prostate cancer and the development of effective chemotherapy treatments.
Today, Chris is the director of MD Anderson’s Genitourinary Cancer Center and the director of the Prostate Cancer Research Program.
Show notes:
[00:03:23] Dawn opens the interview mentioning that Chris went to medical school in Greece and asks if he grew up there as well.
[00:03:43] Ken asks Chris when he first became interested in science.
[00:04:09] Dawn asks if there were a particular teacher or class that prompted Chris’ decision to pursue medicine.
[00:04:39] Dawn asks what led Chris to attend the University of Athens School of Medicine.
[00:05:10] Dawn mentions that in the ‘60s and ‘70s, talking about cancer was almost taboo and asks Chris to talk about the stigma that surrounded cancer for quite some time.
[00:05:57] Ken asks if Chris knew he wanted to specialize in cancers when he first started medical school in Athens or if that interest developed later.
[00:07:06] Dawn mentions that Chris graduated from medical school in 1974 and then took off for Chicago where he had an internship at Cook County Hospital. Dawn asks about the experience, and if it were a culture shock to go from Athens, Greece to Chicago in the 1970s.
[00:08:54] Dawn asks what took Chris to Texas and MD Anderson after his time in Chicago.
[00:09:36] Dawn mentions that after Chris finished his fellowship, he joined the faculty at MD Anderson, and is now coming upon his 50th anniversary there.
[00:09:51] Chris explains his view that we need to better understand the drivers of cancer and goes on to talk about what we currently know about these drivers.
[00:12:06] Ken asks about the significance of the Human Genome Project on cancer research.
[00:13:49] Dawn mentions that along with new technologies, there evolved a strategy of what is called co-clinical investigation where researchers study the mouse, but in parallel look at the difference and similarities with humans. She asks him about how that integrated data required a new language to bring it all together, which is now known as Prometheus. Dawn asks Chris to talk about Prometheus and how this has led to an accelerated understanding of cancer biology.
[00:20:47] Dawn mentions that Chris has studied a range of genitourinary cancers throughout his career, such as germ cell tumors, bladder, and renal cancers, but that his interest in prostate cancer is a more recent development. Dawn asks what led to this specific interest.
[00:23:12] Dawn explains that metastatic cancer was first cured in 1956 when methotrexate was used to treat a rare tumor called choriocarcinoma. She goes on to say that since then, chemotherapy drugs have been used to treat mixed germ-cell tumors and has led to dramatically improved survivorship among patients with metastatic germ-cell tumors. She also mentions that in 1982 Chris published a paper in the journal Cancer titled, “The growing teratoma syndrome,” at which time, tumor growth following chemotherapy for mixed germ-cell tumors had been considered a reliable indicator of a persistent active carcinoma, with the rule being that if the cancer didn’t respond to treatment that operations were fu...
