CRC and IBD have been linked to the volatolome, which is a mixture of volatile organic
compounds (VOCs). The volatolome seems to have promise as a non-invasive biomarker
for the identification of CRC and IBD. Multiple researches have been conducted on the
volatolome's potential, utilising either chemical analysis or pattern-recognition approaches
to determine its potential. The existing literature on the potential of the volatolome as a
cancer and inflammatory bowel disease (IBD) biomarker was examined. The survey
examines 23 journal papers that were obtained electronically through major scientific
databases such as PubMed, Google Scholar, Scopus, IEEE, and Science Direct, which
were searched using sets of keywords. The papers were obtained through major scientific
databases such as PubMed, Google Scholar, Scopus, IEEE, and Science Direct, which
were searched using sets of keywords. Publication of the articles was made possible by the
use of major scientific databases such as Pubmed and Google Scholar, as well as the IEEE
and Science Direct. VOC analyses appear promising for future screening of CRC and IBD,
with potentially improved test performances allowing for earlier detection of IBD and CRC
and consequently earlier initiation of treatment, potentially reducing morbidity and
mortality rates as well as lower rates of (unnecessary) colonoscopies, according to the
studies included.

Background: Colorectal cancer (CRC) is the third most commonly diagnosed cancer
and the fourth leading cause of cancer death worldwide with steadily increasing
mortality rates. The aim of the present study to highlight any relationship between
carcinoembryonic antigen (CEA) and tumor node metastasis (TNM) stage in
colorectal cancer (CRC) patients that would help in diagnosis and staging of the
disease. Patients and methods: A total of 36 patients with stages IV CRC were
admitted to department of General surgery, Zagazig university hospitals and
underwent surgery. Full medical history, clinical examination, General and specific
investigation were performed for all patients preoperatively.The CEA levels for all
patients were examined preoperatively. Results: Our study showed the mean age of
the studied cases ranged from 29 to 83 years with mean 54.36 years. Regarding sex
63.9% were male. Finally 38.9% were smoker. Most common sites of lesions were
rectum, sigmoid colon & descending colon (44.4%, 19.4% & 13.9% respectively).
The diameter of lesion among cases ranged from 1 to 15 cm with mean 5.94 cm and
38.9% had diameter from 3 to 6 cm. Regarding differentiations most frequent was
moderate and mild (41.7% & 30.6% respectively). CEA level among the studied cases
ranged from 0 to 23 ng/dl with mean 6.39 ng/dl and median 4.5 ng/ml. Also 58.3%
had CEA level ≤ 5 ng/ml. Conclusions: There is a meaningful link between TNM
stage and CEA level. However, normal levels of CEA will not rule out CRC
diagnosis, and it can be concluded that these patients should be investigated in

Introduction :
Cancer associated with colon is one of the principal risk factors from decease in women and men. Although importancegrowing aspect of human epidermis receptor2 (Her2)as atherapeutic target is rising butits role as a biomarker in form of predicting indicator indicatorwithin colorectal cancer(CRC)is stilla mystery.Present research isundertakenfor evaluating the of Her2/neu description in cancer of colon.
Material & Method :
This research comprises 256patientswith spectrum of histopathological treatment ranging from colitis to colorectal carcinoma at our department between 2015- 2017. Her2/neu Immunohistochemistry was done in the colorectal carcinomaand scores based on Ruschoff et al (2012) Her-2 testing in gastric cancer.
Result :
Out of total number of 256 cases enrolled in our study group, majority belonged to the age group of 40-60 years, with M:F ratio being 1.4:1. Commonest site of lesion occurred in rectum (43.75%) followed by ascending colon and caecum (12.08%). Non neoplastic lesions constituted about two third of all cases, the commonest being inflammatory bowel disease(21.48%). In benign neoplastic lesions of tubular adenoma was thecommonest type, and in malignant commonest type was colorectal adenocarcinoma NOS(64.44%) followed by mucinous adeno carcinoma (22.22%). Because of more prominent membranous staining observed in high grade colorectal cancers, Her2neu expression is found to be an important predictive marker of carcinoma colon, especially the adenocarcinoma,NOS.
Conclusion : Like Breast carcinoma, target oriented therapy can be instituted especially in Her 2/neu positive high grade and metastatic tumors.
