Geoff Lane - 18 Jun 2008 10:12 GMT This was posted previously in sci.med.diseases.cancer but I was advised to repost here.
My wife was told on Friday 13th (I'm not superstitious but...) that her cancer was no longer curable.
In December 2007 she had an operation on her leg to remove a 11.5cm x3cm x3cm sarcoma, this was completely excised followed by radiotherapy.
Some small lung metastases were noted but in April were considered too small to characterise.
She now has a lump on her scalp that appears to be a metastases but has yet to be confirmed.
Because of an increase in nodules on her lung and in light of the head lump the doctor has stated that the lungs are now inoperable and has suggested 'not too many years left'.
Allalong we have been given the impression that the sarcoma and lung nodules are very slow growing but between April and mid June they've gone from being too small to characterise to incurable.
We have been told that chemo does NOT cure, it merely slows down.
This has been an awful week where the future has been taken away but we are now researching options.
Has anyone any advice as to the chemo treatment, opinions as to Doxorubican or Ifosfamide.
We are now clutching at straws.

After Bob's prompting, I was thinking about finding you clinical trial results on each. However, since you wish to compare notes with patients, thier caregivers or loved ones, the best place for the highest numbers (of responders) on both informations is probably on the private ACOR lists. There's 2 for Sarcoma http://www.acor.org/mlists/mlists.html#s Many of the subscribers may be on both lists. If you click on the high-lighted group name and follow the instructions, you'll be emailed as to how to proceed. You can unsubscribe at any time, if that becomes your wish. Many here also subscribe at ACOR
There are other UK'ers here as well, along with Steph (Oncologist, Radiation Oncologist and more), who trained in UK, but is currently practising in BC, Canada.
I was hoping that you could consult with both the oncologist and a thoracic surgeon in one meeting. And take a tape recorder. It's difficult to take notes, while following along a conversation and you may want a followup (meeting) for further questions / clarifications. Me - trying to be time-efficient, but may not be possible if the experts work out of different hospitals or due to each's schedules. Or maybe the Friday Doctor will try to arrange it for you.
Doxorubicin ? Both are listed here for the common and less common side effects http://www.cancerbackup.org.uk/Treatments/Chemotherapy/Individualdrugs/Ifosfamide
There's also a number at the top (of the web page) if ever you wish to speak to cancer specialist nurse. Try them just for a test. I'm not sure how helpful they might be. I think some UK'ers have found them helpful.
We have something similar in Canada, for general health problems, but if it (the problem's) too complicated or not in their database, all they do is tell us to get to A&E ASAP or see doctor in the morning, so not so helpful, I find.
Please stay in touch and let us know how things go with you and your wife. More questions? Other thoughts. Post away. I'll be here reading and caring. Others too. Best, J

They have shown in man there exists what is called age related iron accumulation. Iron restriction is being used to fight disease. There are many iron chelators found in plant foods. Polyphenols .. flavonoids .. phytate and others.

Top of pageAbstract Iron is suspected to be involved in the induction and/or progression of various human tumors. More particularly, iron may be involved in the pathogenesis of Kaposi's sarcoma, a tumor of probable vascular origin. This study was designed to investigate the effect of iron deprivation on Kaposi's sarcoma. The effects of iron chelators and iron deprivation associated with serum withdrawal were investigated on Kaposi's sarcoma-derived spindle cells, on a transformed Kaposi's sarcoma cell line (Kaposi's sarcoma Y-1) and on endothelial cells, which are the probable progenitors of Kaposi's sarcoma cells. Desferrioxamine and deferiprone, two chemically unrelated iron chelators, induced a time- and concentration-dependent inhibition of endothelial and Kaposi's sarcoma cell growth. The inhibition of cell growth was associated with a decrease in Ki-67 and in both stable and total proliferating cell nuclear antigen expression. Inhibition of the progression through the G1-phase of the cell cycle was further evidenced by decreased expression of cyclin D1 and of p34 cyclin- dependent kinase 4. Terminal deoxynucleotidyl transferase-mediated desoxyuridinetriphosphate nick end labeling assay, flow cytometry with annexin-V-fluorescein and morphologic analysis indicated that iron chelation also induced a time- and concentration-dependent apoptosis. This apoptotic effect was prevented by the addition of exogenous iron. Induction of iron deprivation in the culture medium by serum withdrawal led to similar cell cycle effects, which, however, could only be partly reverted by the addition of exogenous iron. In conclusion, these results show that iron deprivation inhibits the growth and induces the apoptosis of Kaposi's sarcoma cells and of their putative endothelial precursors. This suggests that iron chelators may represent a potential therapeutic approach for the treatment of Kaposi's sarcoma.

Publisher? Advice: create a buzz. 1) Create a book cover (which fits another book you have), with your CV and photo, on the inside of the cover It can always be resized for thickness (after). Create a cover page. 2) Photo of it and blurb about it on a webpage. 3) media contacts you - jump and always have/mention the book (you have media contacts - I have media contacts)
Word spreads - above creates inquiries and demand for it. Due to (until now) unwanted communications, where the person has forgotten to BCC, I have possibly thousands of people I could spread it to.
Problem? You haven't finalized the name or graphics for the cover? The publisher might want different?
Problem ? - ISP's usually only allow webpages under one account? Let me know if you get that far. J

When in fact .. the opposite is true. Those with cancer who receive erythropoietin die at a quicker and higher rate than those who do not receive erythropoietin.

Mike Radcliffe probably wrote something close to that wording. Sorry about your alzheimer's. http://www.fda.gov/FDAC/features/1998/398_alz.html Alzheimer's warning signs include memory loss affecting job skills; difficulty performing familiar tasks; language problems; time and/or place disorientation; poor or decreased judgment; problems with abstract thinking; misplacing things or putting them in inappropriate places; mood, personality or behavior changes; and passivity and loss of initiative. If you notice several of these symptoms in yourself or a loved one, consult a doctor for a complete examination and evaluation.
There are three broad stages to Alzheimer's. In the beginning, the patient may notice his or her own forgetfulness and will solicit others' help or write lists. In the second phase there will be severe memory loss, particularly for recent events. A sufferer may often remember long-ago events while being unable to remember a just-viewed TV show. In this stage, disorientation usually begins, dysphasia (inability to find the right word) may occur, and mood changes happen that can be unpredictable and sudden. By the third stage, people with Alzheimer's experience severe confusion and disorientation, and may suffer hallucinations or delusions. Some may become violent or angry, while others may be docile or helpless. In this stage, sufferers may wander without purpose, experience incontinence, and neglect personal hygiene. Once someone with Alzheimer's becomes bedridden, the complications of bedsores, feeding problems, and infections can make life expectancy very short.
Behavioral symptoms of Alzheimer's result from changes taking place in the brain. The patient neither intends nor can control this behavior. Because families are so often involved in caring for people with Alzheimer's, family education, counseling, and support are vital.

"Iron exposure"
Cancer Lett. 2006 Nov 28;244(1):1-7. Epub 2006 Mar 20. Links Role of environmental factors in the pathogenesis of classic and African-endemic Kaposi sarcoma.Simonart T. Department of Dermatology, Erasme University Hospital, Route de Lennik 808, B-1070 Brussels, Belgium. tsimo...@ulb.ac.be
Kaposi sarcoma (KS) is a mesenchymal tumour associated with human herpesvirus-8 (HHV-8) infection. However, the incidence of HHV-8 infection is far higher than the prevalence of KS, suggesting that viral infection per se is not sufficient for the development of aggressive phenotype and that one or more additional cofactors are required. The great geographical variation in African-endemic and classic KS incidence points to a role for environmental factors in the etiology of Kaposi sarcoma. However, there are few unequivocably established environmental factors involved in KS pathogenesis. This review focuses on the environmental factors thought to be associated with KS, more particularly iron exposure and facilitation of transmission of HHV-8 infection by contact with blood-sucking arthropods.

his disease typically causes tumors to develop in the tissues below the skin surface, or in the mucous membranes of the mouth, nose, or anus. These lesions (abnormal tissue areas) appear as raised blotches or lumps that may be purple, brown, or red. Sometimes the disease causes painful swelling, especially in the legs, groin area, or skin around the eyes.

Résumé / Abstract The role of iron in the pathogenesis of several tumours is being increasingly investigated. In particular, its involvement in the pathogenesis of Kaposi's sarcoma (KS) is suggested by the distribution of the endemic form of KS corresponding to continental rifts and associated iron-oxide-rich volcanic clays. We investigated in vitro to what extent iron supplementation or withdrawal could affect the growth of KS-derived cells, by analysing the effects of adding iron salts (iron chloride and ferric nitrilotriacetate) and/or reducing iron by iron chelators (desferrioxamine) on KS-derived cell cultures. The addition of iron salts strongly stimulated the growth of KS cells, as reflected by increase in thymidine incorporation and cell number. Conversely, desferrioxamine and deferiprone inhibited cell growth. The inhibitory effect of iron chelation was more pronounced on rapidly dividing basic fibroblast-growth-factor-stimulated cells. These results may point to a novel therapeutic approach to KS.

Abstract
We have previously shown that iron may be involved in the pathogenesis of Kaposi's sarcoma (KS) and that the iron chelator desferrioxamine (DFO) inhibits the growth and induces the apoptosis of KS cells in vitro. We treated an 85-year-old man with classic KS with 5 weekly intralesional injections of DFO and observed the opposite effect in vivo. The DFO-treated lesion was characterised by the development of numerous KS papules within the drug diffusion area, whereas no change was noted in untreated or control saline-treated lesions. This suggests that intralesional iron chelators are not indicated in patients with KS.

Iron chelators
Simonart et al currently is investigating the role of regulating iron concentration in tumor cells. They demonstrated that the addition of iron salts strongly stimulates the growth of Kaposi sarcoma and that the use of iron chelators inhibits growth. Their findings are disclosing new therapeutics in tumor management with iron-chelating agents. Hermans et al speculate that the lower risk for developing Kaposi sarcoma in females may be because women have lower iron stores. He also believes that patients with renal transplants are more susceptible to Kaposi sarcoma because they tend to have higher iron loads from repeated blood transfusions.------------------------------

| We are now clutching at straws. | | Geoff Lane Hello Geoff, I am very sorry to read this sad news, but please do not despair. The doctor said "not too many years";he could have said "not too many weeks". Keep on researching those options, you have the time.And be of good heart both of you; new discoveries come up all the time, in fact your researches may turn up something already current.
You ask "We have been told that chemo does NOT cure, it merely slows down."
That is true to a certain extent, but in medical circles "cure" is understood to mean 5-year survival,so using that definition chemotherapy does sometimes "cure".In some other cases chemotherapy is too damaging and has to be discontinued. My own humble opinion is that cancer is not due to a chemotherapy deficiency any more that a headache is due to an aspirin deficiency, so we should look elswhere to help the therapy if we are to have a permanent complete recovery.
The internet is an excellent source of knowledge with first class search engines to help us.It is not the only one however; our local public library can provide the written word to study and will fetch books from other areas if they do not keep the one you seek. Amazon again sells many books on our subject cheaply, and I have made and continue to make good use of it. Make them your sources too.
Your Love for you wife shines through your message: I can understand it because I am married for 57 years.
I do not log on to this newsgroup very often and only write infrequently. If you wish to reply and would prefer not to go public this is my genuine email address. I won't write again on this thread.
With best wishes to you both,
Old Bill.
