 Subsequently in 1983 after the detection of
Helicobacter pylori the underlying association among the causative agent and
gastritis and gastric carcinoma has been increasingly interpreted.

1.      International agency of research particularly in
cancer under world health organization already has categorized helicobacter
pylori as a definite carcinogen in the year 1994


2.       Consequently,
in numerous countries many clinical studies were carried out to judge whether elimination
of H pylori could play any significant role in preventing the gastric carcinoma.
Conversely, due to less sufficient data the conclusions couldn’t be drawn to
prove that h.pylori is the causative agent and its incident seem low.  A randomized study in japan was conducted in
the year 2008, that was actually multicenter discovered that eradication of H
pylori has consequently reduced the occurrence to up to two third of tributary
gastric cancer after early gastric analysis of endoscopic mucosal resection. Signifying
the effectiveness of H pylori eradication for occurrence of gastric cancers. Nonetheless,
this study also exposed that eradication of h pylori did not totally abolish
gastric cancer risk. Hence, in order to completely eliminate the risk for
developing gastric cancer subsequently later than eradication of h pylori, the
periodic surveillance would be recommended periodically.

On the other hand, several other
factors must also be brought under consideration in evaluating whether gastric
cancer can be prevented by completely treating the infection or the risk
factors for its occurrences can be reduced only. Moreover, H pylori infection
has been anticipated to provide some benefits, such as decreasing the risks of
childhood asthma obesity, even though there are no considerable data to support
these benefits of H pylori infections.

As per studies up till now h pylori
has been considered as the major cause of gastric cancers but does not however
proofs it as sufficient for h pylori-associated gastric cancer

 Analogous in theory to human papilloma virus
hepatitis B and C viruses .in precise words this infection is one of the cause
for development of gastric cancers but helicobacter pylori is not the only
reason or is sufficient enough to cause gastric carcinogenesis, several other
risk factors are also involved . Conversely, H pylori is not the only reason of
gastric cancer 5 to 3 percent of the contribution is from the other least
common factors involved such as  of
gastric adenocarcinomas and embrace infection with Epstein-Barr virus,
autoimmune gastritis, genetic abnormalities in the host and possibly proximal
cancers related to esophageal adenocarcinoma. Consequently adenocarcinoma
chances will always be there or would not entirely vanish in absence of
helicobacter pylori infection.


Helicobacter pylori- associated Gastric Cancer

 Epithelial lining atrophy of the gastric canal
is the primary factor to carcinoma it may lead to diminished gastric acid
secretion which directly affects the microbes in the gastrointestinal tract and
worsening the condition. The consequence of each specific infection is not predictable,
as is the degree of advancement of the gastric epithelial mucosal destruction
but still the aggravation in the situation is stopped  by the removal of bacteria. Cancer risk can be
completely eradicated if h pylori is treated before the worsening of the
atrophic destruction of the mucosal epithelium. eradication of h pylori can
either stop or reversed or partially reverse the consequences of worsening of
the carcinomas merely depending upon the extent of atrophic changes that have .the
question arises that why does the risk of gastric carcinoma progression  prevails even if there is a complete
eradication of h pylori done in such cases the secondary reasons responsible for
the issue can be managed like endoscopic surveillance programs that are cost
effective too besides being useful in preventing deaths from gastric carcinoma.



The significance of H pylori
eradication to avert gastric carcinogenesis strongly relies upon the patient’s
degree of severity of cancer at the time of eradicating h pylori.

It has been noticed that the
metachronous gastric cancer risk lies in a range of 1 to 4 % per Anum in those
patients who have already been treated successfully against early gastric tumor
through endoscopic removal but h pylori infection left untreated.

Further study in this area has revealed
that the part of helicobacter pylori in progressing carcinogenesis is actually
through the production of inflammation both as acute or chronic that causes
genetical instability in the formation of the epithelial membrane of gastric tract.
Besides this one more contributing factor is actually the interaction between
pylori and the other microbiomes of the gut, other endogenous may also be
involved in producing carcinogenic products.


There is a particular population who
is affected more often contributing factors are diet and other environmental
factors as well as the food preservation techniques may also contribute to the
occurrence of h pylori accompanying mucosal injury and cancer risk.




Moreover, H pylori infection can cause
genetical instability simply by breaking up the DNA double helix and altering
the micro RNA expressions. One of the most causative virulent strains like CagA-positive
 has even greater potential of causing
gastric carcinoma.


Prominently, no specific virulent strain
of H pylori has been isolated in fact all the virulent and non-virulent strains
have happened to be equally potent in causing carcinomas. However the when
compared between the most virulent and the least virulent strains the
difference between the risks of gastric cancer turned out to be less than 3

The variance in gastric cancer risk amongst
the most and the least-virulent strains is perhaps lesser than three folds, encouraging
the endorsement that all the Helicobacter pylori infections better be eliminated,
regardless of virulence features in short.,




 H pylori eradication abolishes the harmful
triggers and stimulates perseverance of inflammation. Nonetheless, perseverance
of inflammation is an extremely harmonized process controlled by anti inflammatory
drugs, containing lipoxins and resolving acting as a lipid mediators. This highlights
the issue if the h pylori induced inflammation has been resolved so
