What type of cancer is chemotherapy least effective against?What type of cancer is chemotherapy most effective against and the least effective against?
Answer by ƦєdAиgєℓ
Chemotherapy has a 2.1 - 2.3% survival rate on average but the following cancers had 0 survival rate at 5 years - pancreatic, soft tissue carcinoma, melanoma, uterus, prostate, bladder, kidney, multiple myeloma. Testicular cancer (38% survival) and Hodgkin's disease (40% survival) at the 5 year mark.

The reality is that your question cannot be answered with the detail you have provided. The use of chemotherapy depends on several factors (like the type of cancer, the specific chemotherapeutic agent,the disease burden, life expectancy, comorbid conditions, patient wishes) that influence how effective it will be. Cancer is a broad term encompassing many, many malignancies, just as chemotherapy is a broad term encompassing many, many medications.

"Chemotherapy has a 2.1 - 2.3% survival rate on average"... seriously?? lol That is laughable at best. I won't even dig into your 0 survival of your list of cancers, but they're mostly completely inaccurate also. The most and least effective chemo would almost soley depend of the individual. For example, what works for one person may not work for another person with the same cancer.. So if it doesn't work, dr would change to a different chemo and that one may or may not work. If entire tumor can be removed, chemo is still normally given just in case cancer cells are left. If none are left, we don't know if it is or isn't effective in that individual.
You "sir and madame", are the laughable ones here. Get your facts from credible sources, really, like real sources, like from real studies that actually happened...Funny how all your "facts" are from other countries..That right there tells us much...
Abel has a PHD in epidemiology, researchers used him as a numbers cruncher.. When "calculators" start trying to think for themselves, there's gonna be problems..
The Heidelberg biostatistician himself took up pen and brought out a small book with the title: Cytostatic Therapy of Advanced. Epithelial Tumors: A Critique (Hippocrates Verlag, Stuttgart. 112 pages. 28 marks.) Since that time Abel has become a Cain for many West German cancer specialists. Abel admits that in some cases he is no longer invited to participate in new research.
He says in order to find out if chemo really works or not, is to treat some people with chemo and don't treat the rest at all??? Laugable yes, unreliable source of knowledge you are relying heavily on...lol unreliable and laughable, yes..
surprise, surprise...the altmed freaks all came out to give us thumbs down instead of posting intelligent, logical, proven response with sources cited if needed and with altmed, legitimate sources are always needed, but alas...never quite coming to light..
I just got my laugh for the day! QRA is done with a client forming a circle with one thumb and an opposing finger. The client then puts two adjacent finger tips on a part of the body, for example, the liver point. The QRA practitioner then attempts to gently pry the finger and thumb apart. When that area of the body is weak, e.g., the liver, the finger and thumb will come apart easily. If that area is strong and does not want or need any help, it will be difficult to pull the finger and thumb apart.
People pay you for that??? lol
Yeah...drug companies don't cure anything. They manufacture and distribute the drugs.
Lymphoma (including Hodgkin's Disease), Choriocarcinoma, and Testicular cancer
are all potentially curable even after they have spread. Additionally, many other types of
cancer are very manageable even after spreading and many are curable if caught before
spreading.
I'm NED, btw..

Red Angel is correct. According to the study that was done by some Australian oncologists, when a person gets chemotherapy, they have a 2.1% chance of survival in 5 years for all of the cancer's included. The study was called "The Contribution of Cytotoxic Chemotherapy to 5-year Survival in Adult Malignancies. This study took every randomized controlled clinical trial performed in the U.S. from 1990 to 2004 and the results showed the above Cancer cure statistics. According to that study, chemo is most effective against Hodgkin's disease at 40.3% (ABSOLUTE numbers).
In 1989, a German biostatistician, Ulrich Abel PhD, after publishing dozens of papers on cancer chemotherapy, wrote a monograph "Chemotherapy of Advanced Epithelial Cancer." It was later published in a shorter form in a peer-reviewed medical journal.70 Dr. Abel presented a comprehensive analysis of clinical trials and publications representing over 3,000 articles examining the value of cytotoxic chemotherapy on advanced epithelial cancer. Epithelial cancer is the type of cancer we are most familiar with. It arises from epithelium found in the lining of body organs such as breast, prostate, lung, stomach, or bowel.
From these sites cancer usually infiltrates into adjacent tissue and spreads to bone, liver, lung, or the brain. With his exhaustive review Dr. Abel concludes that there is no direct evidence that chemotherapy prolongs survival in patients with advanced carcinoma. He said that in small-cell lung cancer and perhaps ovarian cancer the therapeutic benefit is only slight. Dr. Abel goes on to say, "Many oncologists take it for granted that response to therapy prolongs survival, an opinion which is based on a fallacy and which is not supported by clinical studies."
Over a decade after Dr. Abel's exhaustive review of chemotherapy, there seems no decrease in its use for advanced carcinoma. For example, when conventional chemotherapy and radiation has not worked to prevent metastases in breast cancer, high-dose chemotherapy (HDC) along with stem-cell transplant (SCT) is the treatment of choice. However, in March 2000, results from the largest multi-center randomized controlled trial conducted thus far showed that, compared to a prolonged course of monthly conventional-dose chemotherapy, HDC and SCT were of no benefit.71 There was even a slightly lower survival rate for the HDC/SCT group. And the authors noted that serious adverse effects occurred more often in the HDC group than the standard-dose group. There was one treatment-related death (within 100 days of therapy) in the HDC group, but none in the conventional chemotherapy group. The women in this trial were highly selected as having the best chance to respond.
"April" You need to start using the ABSOLUTE NUMBERS and NOT the relative numbers often used by those that want to skew the results to encourage funding of chemo. You madam, are the laughable one here. Get your facts from credible sources.
EDIT: "April" My you have been indoctrinated well. Because the medical profession in America has gained so much power and money, it is foreign countries that are doing the real research it seems. The drug company studies are the real jokes with all the "Ghost writers" and throwing out the information that does not meet with their agenda and having people like you supporting that insanity makes it difficult to extract the real truth. You simply will NOT find ANY studies done in America that attack the medical industry's use of chemotherapy, it's just too lucrative and way to big of a cash cow.
You still have the brain tumor? How has our modern medicine helped you? Look at Genetic Engineering fiasco; same issue. Only in America do they NOT label GMO foods, but everywhere else in the world they do and the rest of the world has seen the tests and know how bad it is for you, but NOT in America! Same problem.
QRA testing is a very accepted method of testing people for many problems that even doctors have not been able to help. So you know, there is a machine that has been developed that gives data in place of the "O" ring testing you mentioned. It is very sophisticated and not only proves the validity of the "O" ring testing, but is very accurate. You need to update your data bank dear.
Can you name just ONE disease that ANY drug company has "CURED" in the last 100 years? Just one. And don't embarrass yourself by naming vaccines because there is way too much credible data showing how bad vaccines are and how ineffective they are in so many cases.
good luck

Chemotherapy is least effective against low-grade, slow-growing cancers and most effective against high-grade, aggressive cancers. Cytotoxic drugs (doxorubicin, methotrexate, chlorambucil, melphalan, cisplatin, etoposide, busulfan, bleomycin etc) target fast-growing cells, which is why bone marrow, hair follicles and cells of the digestive tract also take a hiding. The histopathology report will include the mitotic count - or number of tumor cells which are rapidly dividing, and the oncologist will decide a course of action based on this information.
Patients with the same type of cancer can have different grade, which is why the use of chemotherapy drugs must be individually tailored.
