I conduct clinical research on a variety of gastrointestinal cancers and provide care for patients with those cancers. We have trials of combined modality therapy (surgery +/- radiation +/- chemotherapy) on gastric, esophageal, pancreas and rectal cancers. We also perform phase I and II trials of biologically targeted agents as well as newer immunotherapeutics. In collaboration with a number of colleagues, we conduct translational studies analyzing novel imaging (e.g. contrast enhanced ultrasound and perfusion scans) and molecular biomarkers (e.g. CDX2 as a prognostic and predictive factor in colon cancer and matrix metalloproteinases as prognostic factors in pancreas cancer). Neuroendocrine tumors, pancreas, colorectal and gastro-esophageal cancers have been areas of particular research focus with multiple therapeutic and translational studies devote to each. Examples of recently completed trials include a randomized phase III trial of a vaccine (algenpantucel) for resected pancreas cancer, phase Ib trial of anti-PD-L1 and separate phase II trials using PD-1 antibody for tumors with micro satellite instability and chemotherapy with angiogenesis inhibitors for advanced neuroendocrine tumors and gastro-esophageal adenocarcinomas. Currently active areas of study include combining immunomodulating antibodies in combination therapy and randomized phase II colon cancer trials of an antibody to interleukin 1 or a first in class agent known as RadioRx. Participation and leadership in NCI cooperative group protocols gives our patients access to the randomized trials that hope to establish new standards of care for a variety of GI cancers.

All is good thank you very much for your services from all the personnel.
Good experience.
Dr. Fischer IS WORTH the wait.
Hurried, late, short quick easy answers!
Dr. Fisher is amazing!!
BAD: Dr. Fisher promptly ended my appointment when inquiry about other treatments at Stanford. He got up and walked out. Very unprofessional!
If you need a great cancer doctor - go see Fisher.
I felt confident that the path I am on is right for me.
Exceptional care from both Dr. Fisher and his PA Ms. Tita. Tita was very courteous, took her time answered our questions explained and walked us through what to expect. As a family we all appreciate the time she took to answer our questions.
All excellent.
Dr. Fisher is not only a very good doctor but also a friendly and caring person.
Dr. Fisher is my hero! He's warm & caring, brilliant & a phenomenal doc. I feel very fortunate to have him quarter-backing my care.
Did not feel rushed.
Dr. Mou & Fisher were both very caring, knowledgeable & helpful. Much confidence in both.
Tita & Dr. Fisher are the BEST.
Very good. Thorough, thoughtful & professional.
Confidence increased with Dr. Fisher's breadth of knowledge. Very pleased.
We got the impression the care provider had very little to say concerning future treatment options, unless the patient is a candidate for clinical trial at Stanford.
Dr. Fisher is great!

Spoke to Dr. Fisher who was very helpful and Dr. Chung who was also helpful in obtaining background information.
Dr. Fisher is the best example of a dr. or what a doctor should be always nice smiling caring I trust when he say something and he listen that what important. Wish they were all like him.
No bad experience.
I am very confident in Dr. Geo Fisher & staff.
Dr. Fisher and his assistant Dr. Mohana Roy are very nice and professional and warm welcome.
Dr. Fisher is not only an excellent oncologist, but also a very pleasant person to deal with. I am well pleased with his care.
Dr. Fisher is well regarded and seems to know his science well. I think he serves more patients than ideal. My biggest concern is that he is treating my cancer - not ME and often doesn't refer me to others or explain why not.
I have the deepest confidence imaginable and the very highest regard for every staff member with whom I have had contact!
The world would be a better place if all the dr. were a great as Dr. Fisher.
Blessed to be in the hands of this man.
I love Dr. Fisher & if the need arises I whole heartedly recommend him!

Dr. Fisher is an outstanding doctor - He has provided excellent care for several years and has a very pleasant personality.
MD fellow spent hour with me - excellent ...; MD Fisher - IS but reinforced fellow assessment.
Felt compassion.
Dr. Fisher was calling direct & had taken the time to "know about my issues. He has 'a way" that makes me feel that all will be OK his nurse was also very caring. He is amazing!!
Dr. Fisher made an effort and perhaps even saw me out of his regular visiting hours, nurse Jackie was the most attentive of RN's & so was Scott!!
Totally pleased with Dr. George Fisher & the staff surrounding him.
Off the scale great!
We have the utmost trust in Dr. Fisher!
Great Doc in George Fisher competent/caring/ a great person.
This visit was a little rushed.
I arrived feeling considerable concern about a pair of conflicting test results, and I departed with a sensible plan that left me feeling much relieved.
Dr. George Fisher is an excellent doctor. I've seen him for 14 years now -
Dr. Fisher seemed hurried.
Dr. George Albert Fisher is one of the kindest drs. that I know. He consistently takes the time to explain and lets you know what is going on and next steps if any. You can be very candid w/him and he is very honest w/your & your family.
Love Dr. Fisher call his fellow & trial people.
Dr. Fisher has taken excellent care of me.
After the clinical trial stopped working for my husband, Dr. Fisher pretty much told us that I cannot do anything about your condition anymore, so why don't you go to UCSF and ask them if they have clinical trials for you. He suggested for my husband to take Lonsurf in the meantime. Is this how Stanford treat their patients? No feeling of concern or compassion at all.
We came to Stanford for a 2nd opinion on a cancer diagnosis. Not only did Dr. Fisher give us a 2nd chemo to try (& hope) when he was I was taking notes he spelt the medication names and medical terminology for me.
Dr. Fisher is extraordinary in his handling of cancer patients like myself explaining everything in detail. He treats me as a family member and I rely on his expertise.
I so appreciate Dr. Fisher's willingness to take the time to talk with me, and still try to be on time for his other patients. I am willing to wait, because I know he takes this time with everyone.
outstanding doctor
Dr Fisher provided detailed information and answered my questions.
My doctor has always been extremely kind and compassionate. He shows true concern for my condition and always makes sure I have solutions or answers to all of my concerns. He is very knowledgeable about the medical condition I'm going through.
With delight I recommend to other people.
Dr. Fisher & his team provide great patient care!
Dr. George Fisher & staff are incredible. Stanford is excellent!
Very happy with Dr. Fisher and his staff especially Melissa Worman and nursing staff at 800 Walsh Rd. Research facility.
I trust that I am getting the best care possible, but I don't believe the doctor is being completely transparent with me. Last month, he proposed one course of treatment and this month he is proposing something different. It looked like I would be part of a clinical trial and now there are numerous reasons why I can't. I am very frustrated with the experience.
Dr. Fisher is a very kind doctor. He is also at the top of his field. How lucky to have such a wonderful doctor. He may be our life saver.
Wonderful man.
All good.
George Fisher is amazing - wonderful doctor and a very kind man
Dr Fisher is the best so caring and kind .
Dr George Albert Fisher and his team consistently provide information updates for the care and treatment of myself
Would like written explanation of decision rather than quick phone call. Decision was not made at time of consultation and no follow-up appointment.
I have referred MANY patients to Dr. Fisher, they all think he is the greatest - and he is.
Dr. Fisher appears over whelmed by patient care load. Very upset he did not discuss test results.
Always a pleasure to meet w/George Fisher.
An amazing experience - Dr. Fisher is a world leader in treatment of my condition, and spent a long time in evaluating & explaining my problem.
I wasn't given instructions for when to follow up with Dr. Fisher for my next appointment.
Excellent staff.
Wonderful dr.
Dr. Fisher was excellent.
Dr. Fisher is wonderful! Kind, patient, and knowledgeable! Thorough, clear in communication, listens well and shows compassion.
Dr. Fisher sat with me to demonstrate the findings on the CT images -> outstanding.
Dr. knew it was a 4 hr. drive & took trip in severe pain only to be told bluntly there was no hope. Very horrible experience even if it was true no feelings or care shown.
Very good -
Dr. Fisher and his staff always care about me and my condition - I feel like more than just another patient.
Why was I in so much pain? No answer.
