Hi,
From what I learn so far from the ASCO 2011 conference as a PATIENT,I will make sure and remember where (which hospital) I got my biopsy or resection done ;so that I can retrieve my tissue sample from the FFPE -the slide from the pathology lab that make my CC diagnosis-.This will be very useful for future biomarkers assay to improve the treatment outcome if needed.
(most hospitals in U.S. will keep your FFPE for 5-10 years. ) ;AS far as I know,only M.D.Anderson and Massachusetts General will automatic perform this kind of test for cancer patients.
There are a lot of companies will perform the tests for you if your doctors requested for you.The diagnostic companies will do all the work for you but you have to know where your FFPE were.Most of the time the laboratory in your hospital will coordinate the whole thing for you because some of tests may require serum or blood samples instead of tissue from the FFPE slide.Inostics from Hamburg,Germany;Surexam from Guangzhou,China;Panagene from Daeieon,Korea;Quest diagnostics and bioTheranostics in US to name a few.
If the insurance companies won’t pay for it; Most of them will accept your private payment.I check with one company just for info.A colorectal cancer biomarkers Assay which included TYMS mRNA,ERCC1mRNA.VEGFR1 mRNA, VEGFR2mRNA, KRAS mutation,BRAF mutation,P13K mutation and UGT1A1 SNP costs under 900 U.S. dollars. The tests will tell you whether you will be resistant to platium-based chemo or sensitive to Avastin/sorafenib/cetuximab/irinotecan and 5FU.
Of course,the quality of each lab which perform the tests will be different and require careful selection; but the future of personalized medicine is already here and as patients, we should prepare accordingly to increase the odds of our survival now.
Please read the article”ASCO 2011-the challenge and progress of the genomic eara” provided by our Gavin under the” web site forum ” on this CC web site.Hello – Thanks to everyone who posted a response to my Mom’s inquiry about the benefits of chemo after major Liver resection. She has since seen 4 different oncologists in the Washington DC area and like that old joke, has received 5 different opinions. Two of those opinions – which I must mention came from the ‘older’ physicians – included fairly lengthy course of 5 day week radiation possibly including chemo such as Xeloda or 5FU –
Has anyone who has undergone a ‘successful’ Liver resection with seemingly negative margins also had heavy duty radiation?? Does it make sense to radiate the entire region of the surgical site without a known tumor??
This question – of radiation + chemo vs. chemo alone has us all very confused.
BTW – The MDs who recommended chemo alone – one suggested Gemzar + Cisplatin the other recommended FOLFOX – any feedback on the chemo is certainly appreciated as well.
Thanks again.

Hi,
Thanks this foundation for providing me the opportunity for attending this conference. I have learned a lot and next time I will have a better strategy to spend my time between speaker sessions and the poster sessions. I did not have enough time for the poster sessions because I think I can read them later.(I have marked down 20+ of the posters that I want to check out,but I have only time for 2 of them.)
The following is one of the few I have come across that is of interest and relate to CC.(It received DDW poster of distinction award)
Do not worry about the title,I will try my best to explain it in layman’s terms.Title; Prognostic impact of Thymidylate Synthase(TS) Expression in Adjuvant Gemcitabine plus S-1 chemotherapy after surgical resection for Bile Duct cancer.
Authors:Hironori Kobayashi MD and 9 other Md from the dept. of Surgery,Div. of Clinical Medicine Science,Graduate school of Biomedical sciences,Hiroshima University.
Objective:The aim of this study was to investigate whether the TS,DPD, or OPRT expression can predict survival of advanced CC patients treated with gemcitabine(GEM)+S-1(a novel oral 5FU combination including tegafur,which similar to Capecitabine-also a prodrug of 5FU,DPD inhibitor and OPRT inhibitor.
Study Samples included 106 CC patients (stage II,III,IV)who had R0,R1 resection between 1989-2010 at Hiroshima hospital.(single location,not multi-center study)
Conclusion: Low intratumoral TS expression was associated with INCREASE overall survival in CC patients who received adjuvant GEM+S-1 chemotherapy after surgical resection.
TS therefore is a relevant PREDICTIVE MARKER of benefit from adjuvant GEM+S-1 chemotherapy in resected CC patients.Following is my thinking about this study:
TS,DPD and OPRT are emzymes that related to the metabolism of the drug 5Fu and thus the effectiveness of the 5FU prodrugs like capecitabine and the like.
The study indicated if TS marker is high(that is 30% or higher in expression)the 5 year survival rate is 25% as compare to low TS expression is 81% when CC patients are on the GEM+S-1 chemo treatment.(If that is true, and if my TS marker is high,I will suggest to my oncologist to change Gemcitabine and Xeloda and use a different chemo agent that is different in chemical structure to Gemzar and 5 FU. Again this is my personal point of view only and it can be wrong in terms of outcome. Remember this study is the forefront of reseach and not the final phase III clinical trial or approval of a drug or marker.)
The study also indicated that there is NO significant difference in overall survival between the high TS group treated with the GEM+S1 and NO adjuvant chemo treatment group.
Therefore the TS marker may be of value in choosing the appropriate chemo treatment before it starts. and it may be of value in future drug development as well.
DPD and OPRT expressions were also mentioned in the study but they did not make any conclusion about them as potential markers for CC patients.So I presume both of them( the DPD and OPRT inhibitors in the S-1 regimen is not of value as markers at this point .)
I will also try to find out where and how to get the TS marker test done if available. I appreciate if our Gavin can provide his valuable research skill on this thymidylate synthase marker(TS).Gavin is an important resource and asset for information on the internet for this foundation.
I hope this is of interest to you in the research of treating CC .
God bless.I can’t believe I just found this site. My husband was dx with extrahepatic cholangiocarcinoma 11 months ago. I did every search you can imagine and never saw this site. The only thing the Doctors gave us was the Pancreatic support sites. But now I am here and will get started.
My husband has been a very healthy man throughout his life. He did smoke and drink but quit smoking nearly 18 year ago and drinking 21 years ago. The drinking was selfmedicating for PTSD. Last winter he seemed to be aging before my eyes and had no energy. Things came to a head in June. Urine turned dark, stools light, no appetite and itching. I had thought his sclera was a little yellow but they never seemed very white so didn’t really get concerned until he mentioned itching. By the way, I am a nurse.
I called his primariy care at the VA on Monday June 14th and they instructed us to go to the ER. Well 10 hours later we were told he had a tumor and they were going to do a CT scan that night. The next morning we were told he had pancreatic ca and that a referral had been placed to see the GI doctor. On Thursday they did the first ERCP and obtained brushings. The next day they did another ERCP with needle biopsys and placed a stent. We were told they couldnt definitly say it was cancer but their experience told them it was and a request was sent to the chief of staff for a fee basis surgical referral since the VA did not have anyone qualified to do the surgery. Over the next 24 hours, all his jaundice and symtoms went away with the stint in place.
The oncologist told us he had 6 to 12 months and really got things moving. . We saw the Dr. DelCore at KU and he did a whipple on July 27th. The CA was in the pancreas but all margins were clear and only 2 out of 10 lymph nodes were positive. He has followed up with 1 cycle of Gencitibine, 28 radiation tx with 5FU and then 3 more cycles of Gencitibine. He had his last Chemo last week with a followup scan. We are now awaiting results of that scan. Oncologist says they will followup every 2-3 months and she would expect it back in 2 years.
This year has been difficult. I remember in June and July, every time we were driving to the Dr. or hospital, we would hold hands and say we felt we were driving to the gallows. I am hoping that now his tx’s are over he will get to feeling better and we can do some things to enjoy our life together.
