Talk:Stomach cancer

Epidemiology
I don't think this article deals with the epidemiolgy of gastric cancer very well. It even implies that the UK has a high incidence, in the textbook general and systemic pathology by JCE Underwood, it says the highest incidence is in Japan, China, Columbia and Finland. It says that there is a low incidence in the UK and USA. I heard that due the the high prevelance in countries like Japan they have started screening programmes which means although the incidence is worse in Japan the cancer is often caught early which means the mortality rate in Japan is better than in countries such as the UK and the USA. I think this information is important and should be included in this article. Darrkwings 10:39, 30 September 2007 (UTC)

Headline text
Other pages, this page has public domain data from a brochure. While the data is relevant, it is formatted in a way that seems, well, like it belongs in a brochure. This is meant to be an encyclopedia so this needs to be looked into in the long run. -- Alex.tan 15:13, 7 Oct 2003 (UTC)

There's also a lot of general, non stomach cancer specific information. This should all be taken out and wiki linked instead. MH 2004/4/11

Four paragraphs removed
I removed the following four paragarphs, because they don't relate to Stomach cancer per se. Any objections? --Arcadian 18:32, 10 January 2006 (UTC)

''Many patients with cancer are motivated to learn all they can about the disease and their treatment choices so they can take an active part in decisions about their medical care. The doctor is the best person to answer questions about their diagnosis and treatment plan.''

''When a person is diagnosed with cancer, shock and stress are natural reactions. These feelings may make it difficult for people to think of everything they want to ask the doctor. Often, it helps to make a list of questions. Also, to help remember what the doctor says, patients may take notes or ask whether they may use a tape recorder. Some people also want to have a family member or friend with them when they talk to the doctor -- to take part in the discussion, to take notes, or just to listen. Patients should not feel the need to ask all their questions or remember all the answers at one time. They will have other chances to ask the doctor to explain things and to get more information.''

''When talking about treatment choices, the patient may want to ask about taking part in a research study. Such studies, called clinical trials, are designed to improve cancer treatment.''

''Patients and their loved ones are naturally concerned about the effectiveness of the treatment. Sometimes they use statistics to try to figure out whether the patient will be cured, or how long he or she will live. It is important to remember, however, that statistics are averages based on large numbers of patients. They cannot be used to predict what will happen to a particular person because no two cancer patients are alike; treatments and responses vary greatly. Patients may want to talk with the doctor about the chance of recovery (prognosis). When doctors talk about surviving cancer, they may use the term remission rather than cure. Even though many patients recover completely, doctors use this term because the disease can return. (The return of cancer is called a recurrence.)''


 * Agree with the removal. Andrew73 18:36, 10 January 2006 (UTC)
 * Totally agree, and article needs some more clean-up. I'll start when I have some time.  -- Samir ∙ TC  [[Image:Flag of Canada.svg|25px|  ]] 09:18, 24 February 2006 (UTC)
 * I disagree with the idea of removing the reminder to patients about how they should best proceed. Even though those paragraphs do not pertain to stomaach cancer per se, the people who come to this site, for the most part, are not gastroenterologists; they are people who have either received the diagnosis or are very close to someone who did. These lay people are not thinking completely clinically when they turn to this site and they can use this additional reminder of how to proceed with the influx of info they are about to have to absorb.  dwinetsk 18:07, 12 March 2006 (EST)
 * I concur; after all aren't we meant to come from a neutral point of view? This hardly sounds neutral to me. Fuse809 (talk) 17:44, 3 April 2014 (UTC)

why remove external link to important gastric cancer info?
Why remove the link to HDGC information? It's stomach cancer, a genetic form, and people need to know about it.


 * Inserting a link is not the same as providing information. If you truly want to provide information, just write a few lines in the article. The external link can then be used as a reference, although I would personally prefer an actual journal reference to a recent peer-reviewed article. Please review External links.

Unintelligible sentence
Would it be possible to clarify the following sentence? It does not seem to make much sense to me, although I'm not sure whether it is because I am not used to medical-speak, or simply because it indeed has a grammatical problem: "Stomach cancer represents roughly 2% (21,500) cases of all new in about 80% or more of gastric cancers."

Thanks!

Even if the sentence read "Stomach cancer represents roughly 2% (21,500) of all new cases in about 80% or more of gastric cancers" it would still not make any sense, because stomach cancer and gastric cancer are the same thing. There has to be some way of marking this sentence as being awkward. --NJ 16:16, 31 December 2014 (UTC) — Preceding unsigned comment added by Njain1091 (talk • contribs)

Pain Killers
I removed the statement "It is more common in people who take in pain killers in excess and frequently", for two reasons. First, I don't know which the author intended to implicate: narcotics (as in opiates), or non-narcotics (ASA? APAP? NSAIDs?). Second, if indeed referring to NSAIDs, it may be confusing frequent use with causing ulcers (which is indeed possible). But among various sources I consulted, none gave "painkillers" nor "ulcers" as a risk factor for stomach cancer. Ordinarily I might place a {cn} here, but I'd rather hold medical info to a higher standard. If this is reverted, it should be clarified. &mdash; VoxLuna   T /  C  07:44, 11 February 2007 (UTC)

Request for editors and contributors
SUBJECT OF POST: Request for editors and contributors

REASON FOR REQUEST: My wife and beloved partner in life for 26 years was recently diagnosed with stomach cancer with possible involvement of the liver. Current statistics (1995-2000) indicate a 5 year survival rate of about 5% of patients with this condition, with most oncologists believing that survival up to 2 years with aggressive treatment is as good as it gets.

While the current information in Wikipedia is helpful, I would like to suggest the following additions for this entry and all other entries regarding medical conditions. They include, but are not limited to, a portal or a section that would provide:

(1) Translation of medical and scientific information into terms a layman can understand, including a layman's dictionary of medical terminology.

(2) Links to online and print journals dealing with the particular subject at hand.

(3) Links to and lists of Usenet Groups and online or offline regional support groups for the particular subject at hand.

(4) Links to and lists of treatment centers for the particular subject at hand, along with their location and rates of success.

(5) Links to recent and archived online articles regarding the particlar subject at hand.

(6) Information regarding experimental and non-approved treatments for the condition.

(7) Information regarding suggested dietary, nutrition,and dietary supplements for the condition.

(8) Any other information that would be helpful to patients and their families.

These (and other) additions to the article would be helpful to the public for whom supplemental information such as this is vital.

Staging
Under "Staging", the article says "Stage 1B may be treated with chemotherapy (5-fluorouracil) and radiation therapy." Does this mean "instead of surgery" or "as well a surgery"? Reading on survival rates further down, this would seem to be significant information.

Merged section on animals is useless
Currently it doesn't even mention animals. It needs to either be expanded to give more information on how stomach cancer presents and is treated in animals, or deleted. --Cptbigglesworth266 (talk) 10:30, 14 April 2015 (UTC)

Genetic/hereditary component
"Approximately 10% of cases show a genetic component.[37]" IANAD but I don't think this is quite right.

The linked reference states, "approximately 10% of gastric cancers show familial clustering", and later, "the ratio of hereditary gastric cancer, according to the criteria of the IGCLC, is 0.3%–3.1% of all gastric cancers". The linked reference from there concludes, "According to the Minimal Criteria of ICG-HGC, the incidence of true and suspected HGC was 3.1% (6 probands) and 11.3% (22 probands), respectively, out of 195 gastric cancer patients."

Not sure how to clean this up adequately, but at present this (and the similar statement in the introduction) seems to be misinformation. 64.229.4.53 (talk) 00:56, 19 March 2016 (UTC)

Removal of unreferenced material
I am editing the sentence which states 'common causes include eating picked vegetables and smoking'. The text confuses 'cause' with 'association' - indeed, later in the text is says that there has been no 'causal link established' with diet and stomach cancer. The link with smoking is referenced in another part of the text, so that's fine, but the claim that eating picked vegetables is a 'cause' of stomach cancer is not supported by the references. Fortnum (talk) 18:01, 16 May 2017 (UTC)
 * There is a fine distinction in medical terms between 'cause' and 'statistical association'. One might even suggest in evidence-based medicine that a 'cause' can be considered as an example of a high correlation coupled with a plausible mechanism. In the case of stomach cancer, the difference between its link to smoking and that to diet seems more like a difference of degree than one of distinction. When an editor is summarising the text of an article section for the lead, it is usual to paint the picture in broad strokes as in 'common causes include eating picked vegetables and smoking', since the general reader (at whom the lead in particular is pitched) is less likely to be concerned with precise terminology. Nevertheless, I've attempted to cover the point by re-writing that sentence as "Smoking is another common cause,[ref WCR2014] and other risk factors include diet and obesity.[ref pmid24011243]". Does that go some way to meeting your concerns? --RexxS (talk) 10:58, 20 May 2017 (UTC)
 * Rates of stomach cancer very widely. Japan screens for stomach cancer as the condition is so common there. This is believed to be do to pickled vegetables? Did you read the reference provided? Doc James  (talk · contribs · email) 21:49, 22 May 2017 (UTC)
 * I can find a reference saying that pickled vegetables are associated with stomach cancer, but I can't find the one that says they are a direct cause. Can you help me out with a quote, James? As there are many other dietary factors associated with GC, such as fruit, flavonoids, total antioxidant capacity, green tea intake, heme iron intake from meat, salt and even aspirin – as well as obesity per se(24011243), I'm not sure that the lead is the best place to single out one item. I think I'd prefer the lead to name "diet and obesity", and let the interested reader either read the Stomach cancer section or the references. --RexxS (talk) 22:49, 22 May 2017 (UTC)

Okay it says "Helicobacter pylori is the major environmental cause of gastric cancer development. Other factors contributing to risk include dietary composition – particularly intake of pickled vegetables – and smoking." Doc James (talk · contribs · email) 23:26, 22 May 2017 (UTC)
 * Thanks James, that's fine. As the World Cancer Report singles it out for special mention, I'm happy to see it in the lead. Cheers --RexxS (talk) 10:08, 23 May 2017 (UTC)
 * Perfect. While pickled vegetables are not a big deal in N America and Europe as people do not eat many, in Asia and specifically Japan and Korea they represent a major cause. Doc James  (talk · contribs · email) 15:38, 23 May 2017 (UTC)
