091001 - Follow up ref SDS 3 0000.
091002 -
091003 - Reuters reported today that...
091004 -
091005 -    1.  Femara reduced recurrence of breast cancer by 43% in a major
091006 -        5-year trial of about 5,200 women.  Scientists stopped the test
091007 -        half way through to allow all of the patients to take advantage
091008 -        of the stunning success rate. ref OF 1 0001  Femara is a new
091009 -        pill made by Swiss drugmaker Novartis. ref OF 1 4M5I
091011 -         ..
091012 -    2.  Letrozole is the generic name for Femara, and is one of a class
091013 -        of cancer drugs called aromatase inhibitors, which suppress the
091014 -        production of estrogen.  AstraZeneca has a drug of the same
091015 -        type called Arimidex. ref OF 1 4M96 and ref OF 1 4M4G
091017 -         ..
091018 -    3.  Breast cancer strikes again in one out of two women within five
091019 -        (5) or more years after diagnosis. ref OF 1 4M89
091021 -  ..
091022 - This report aligns with correspondence from people who have seen SDS
091023 - records on the Internet while searching for remedies after suffering
091024 - recurrence 5 years after initial symptoms and treatment for breast
091025 - cancer.  Reuter's reporting also adds urgency to inquiry from Doctor
091026 - Johnson on 030606 for proactive diagnostics, testing and treatment.
091027 - ref SDS 1 NE6F
091029 -  ..
091030 - Reuter's article continues...
091031 -
091032 -    4.  Tamoxifen is currently the most widely used treatment for
091033 -        breast cancer, but loses effectiveness after five years,
091034 -        ref OF 1 4M89, so the new treatments with Letrozole seems
091035 -        potentially significant for avoiding recurrence in 43% of
091036 -        patients after 5 years.
091038 -  ..
091039 - Seems curious that Doctor Johnson has not discussed treatments using
091040 - Tamoxifen during remission to avoid relapse and recurrence cited in
091041 - the article today.  On 030606 Doctor Johnson was asked about proactive
091042 - treatments and seemed to indicate at that time that prevention is not
091043 - effective for breast cancer. ref SDS 1 NE6F  He made a similar point
091044 - on 030710, ref SDS 2 7C6W, and went on to say that treatments become
091045 - less effective over time, but cited no evidence. ref SDS 2 OW3O  The
091046 - article today appears to support Doctor Johnson's theory in relation
091047 - to treatment using tamoxifen. ref SDS 0 4M89
091048 -
091049 -     [On 031205 did not discuss drug treatments to reduce chance of
091050 -     relapse. ref SDS 5 GX6G
091052 -  ..
091053 - Reuter's article continues...
091054 -
091055 -    5.  Tamoxifen works by blocking the estrogen receptor on cells --
091056 -        the molecular doorway that estrogen uses to get into cells.
091057 -        But it can also, paradoxically, stimulate this receptor.
091058 -        Scientists believe that over time, this stimulation becomes
091059 -        greater, interfering with tamoxifen's ability to prevent
091060 -        cancer. ref OF 1 4N35
091062 -  ..
091063 - Millie commented that her cancer is not related to estrogen and so
091064 - cannot be treated by tamoxifen, which is suggestive that letrozole
091065 - might not be effective for Millie.  What is the alternative treatment
091066 - to reduce the risk of relapse for the type of cancer Millie has?
091067 - Merely, because letrozole is more effective than tamoxifen for
091068 - preventing recurrence of estrogen-based breast cancer does not
091069 - necessarily mean it is not more effective than current measures for
091070 - preventing relapse in Millie's case.
091072 -  ..
091073 - What does the literature say?
091075 -  ..
091076 - Reuter's article continues...
091077 -
091078 -    6.  Aromatase inhibitors such as letrozole suppress the production
091079 -        of estrogen. Side effects include increased risk of
091080 -        osteoporosis, hot flashes, night sweats and pain in the bones,
091081 -        joints or back. ref OF 1 4N46
091083 -         ..
091084 -    7.  Since the recurrence rate for breast cancer is 50% within 5
091085 -        years, reducing this rate by 43% shown by the study is a sea
091086 -        change in the treatment of the most common form of breast
091087 -        cancer. ref OF 1 4M5P  The New England Journal of Medicine
091088 -        released the findings ahead of its Nov. 6 print issue because
091089 -        of their significance. ref OF 1 4M64  Doctors said the study
091090 -        offers a new direction to treat patients who have the
091091 -        hormone-receptor positive form of breast cancer in which
091092 -        estrogen fuels the cancer. ref OF 1 4M75
091093 -
091094 -
091096 -  ..
091097 - Submitted the following letter to Millie notifying about this
091098 - promsiing new treatment....

091107 -    2.  Mil,
091109 -         ..
091110 -        Here is the record on the article we discussed this morning
091111 -        that reports a major study showing that a new drug treatment
091112 -        reduced recurrence in 43% of patients for estrogen based
091113 -        cancer, cited in the article as the most common form of breast
091114 -        cancer. ref OF 1 0001
091115 -
091116 -            [On 031011 letter to Pam notified about this promising new
091117 -            treatment to reduce chances of relapse, and plan to discuss
091118 -            with Doctor Johnson in November. ref SDS 4 AG5M
091120 -         ..
091121 -    3.  The article says the new treatment significantly improves
091122 -        results using tamoxifen for treating estrogen based cancer.
091123 -        ref SDS 0 4M4G  You noted that your condition is unrelated to
091124 -        estrogen, and so the relevance of the new treatment is
091125 -        questionable, ref SDS 0 4N35 but may justify some talking
091126 -        points concerning the 5 year issue, when you meet with Doctor
091127 -        Johnson next month.
