After the Kochi meeting, I went on a vacation trip into China, to visit
my friend Dr. Si Yun Shu, Director of the Institute of Neuroscience at
the First Military Medical University of China, in Guangzhou, and Chairman
of the Department of Neurobiology. I had met her years ago when she was
doing a post-doctoral fellowship with my father, Dr. Harry Wilcox, who
was a professor of Anatomy at the University of Tennessee.
One afternoon she hosted a conference on VHL for faculty and medical
students of the university, and physicians from the hospital. Dr. Kai-Tai
Yao, a professor in the cancer center and a member of the Chinese Academy
of Sciences, gave an overview of VHL in Chinese.
Then I gave my talk in English about VHL, the VHL Family Alliance, and
the Kochi meeting. I talked about the various aspects of VHL and how doctors
have been able to increase the rate of diagnosis in other parts of the
world. If there is one case of VHL in 32,000 people, then there must be
30,000 people with VHL in China. The keys in other countries have been
to raise consciousness among physicians of the various aspects of VHL,
to suggest when to screen and do differential diagnosis for VHL, and then
in addition to make information available to patients and physicians about
how to manage one’s health.
They were very engaged and asked very good questions. One doctor asked
if there were a VHL Family Alliance chapter in China. I said not yet,
but we are of course glad to work with a Chinese affiliate group. For
example, a Chinese discussion group on the internet might be the first
place to start. With such a large country, high internet connectivity,
and such a low rate of diagnosis at the moment, it will be hard to link
people together across such distances.
My vacation trip took me on to Beijing, where I met with Dr. Kan Gong,
a Urologist, from the First Hospital of Peking University. I had met Dr.
Gong at the Kochi meeting.

Ning Liu, Dr. Zheng Zhao, Dr. Ning Zhang, and Dr. Kan Gong, Department
of Urology, Peking University Hospital, Beijing
The members of the Urology Department presented their research
to me, each in turn. They are all studying some aspect of VHL, mostly
changes in the VHL gene in sporadic tumors rather than focusing
on the VHL syndrome. Dr. Liu in particular has a collection of 89
kidney cancer tumors, and has found changes in the VHL gene in 55%
of his samples. He has also collected non-tumor tissue from these
same patients for comparison, and only one has VHL syndrome.
They are doing some very interesting work on HIF-1-alpha and VEGF.
They have published papers in Chinese. Through the Kochi meeting
they will be connecting with other researchers doing similar work
in other parts of the world. Dr. Gong was very enthusiastic about
the contacts he made in Kochi.
I gave the presentation I had prepared for Guangzhou and we talked about
VHL in China. We talked about strategies that have been used in other
countries to raise the rate of diagnosis over the past ten years. This
team has currently asked doctors throughout China to refer to them all
cases diagnosed with VHL. I said that in other countries it has been helpful
to broaden the request -- ask to see all patients with RCC tumors who
are under the age of 40, or who have tumors on both kidneys. In this way
they are likely to find not only VHL but also other hereditary cases of
kidney cancer.
Dr. Gong was very impressed with the family interaction in Japan, and
hopes to help create a similar family alliance in China. I said that we
would be happy to share information and interact with the group, and explained
how we work with other international affiliate groups. It takes a certain
amount of energy from the families as well, so we will all look for a
few good family members who can help to bridge the language gap and link
China with the resources available in English and other languages.
In the two months since these meetings we have come into contact with
two new VHL families in China, and Dr. Shu has been helpful in finding
a capable neurosurgeon for one patient. We are looking forward to strengthening
these new ties with Asia.
