Based on a retrospective, population-based dataset, CRC incidence appears to have remained static over the past 5 years in the United States. Incidence rates continue to be higher in blacks than whites, and higher than rates in people with socioeconomic disadvantage. Further studies are needed to confirm these findings, and to assess whether changes in CRC risk factors have contributed to the racial disparity in incidence rates.
A variety of treatments are prescribed for colorectal cancer patients, with chemotherapy being the most common. Surgery is also widely used, with curative intent in many cases and palliative intent in many others.\n
Colorectal cancer is a type of cancer that forms in the large intestine (colon). Most cases of colorectal cancer occur in the small bowel, but it may form in the rectum. It is a disease with some of the highest mortality rates in the UK, with about 5,000 cases per year. It is suspected that colorectal cancer is linked with smoking or diet. It also appears to affect people of all ages.
Cancer in the colon is a disease of aging. The most common cause of [colorectal cancer](https://www.withpower.com/clinical-trials/colorectal-cancer) in non-smokers are hereditary. Smoking is an important risk factor for colorectal cancer, especially for those who develop the disease at an older age. Women who smoke less than 20 cigarettes per day have a 30% lower risk of colorectal cancer than non-smokers. The risk of colorectal cancer is also increased in those who drink less than 1 beer per day. The greatest risk declines to 10% if one drinks 1.5 beer per day. Eating the same number of vegetables at breakfast and lunch each day may reduce the risk of colorectal cancer by about 30%.
Colorectal cancer can be cured within 3.5 years in a significant number of patients, but it is most likely to occur after 3.9 years, which corresponds to a cure rate of 58%-83%.
There are several possible signs of CRC. These include rectal bleeding. Anemia is common as well and most colorectal cancer patients are anemic at time of diagnosis. However, not all CRC patients present with a palpable mass or the typical bloody diarrhea of CRC, but this is more frequent among patients with proximal and sigmoid carcinoma. Any abnormality of stool appearance and consistency should be investigated further with further testing and prompt referrals for medical care.
We have previously reported that tepotinib inhibits human cell growth through induction of G1 arrest and induction of cell apoptosis in both in vitro and in vivo settings. Here we confirm these antitumor activities, and demonstrate that tepotinib also elicits specific antiproliferative effects in colorectal cancer cells that is not achieved at nontoxic concentrations.
Colorectal cancer is a fairly rare but serious disease; it causes a large proportion of deaths in those who are diagnosed with the disease. However, in the past 20 years, colorectal cancer death rates have declined, from over 15 to 7 per 100,000 per year before the year 2000 to around 5 per 100,000 per year in 2008, which suggests that colorectal cancer is being successfully treated. Nevertheless, it would seem that this may not be the case if colorectal cancer is being detected later, which seems to mean that many patients are not being diagnosed with early stage cancer.
Tepotinib can be regarded as an effective and safe agent for treating patients suffering from non-small-cell lung carcinoma (NSCLC). Tepotinib had a better survival outcome for patients who had tumors with EGFR mutations compared to those without EGFR mutations. Thus, EGFR mutations may be a new biomarker that may serve to select patients with NSCLC who have a better chance for having a better survival time. Findings from a recent study from the first phase II study of tepotinib were encouraging, suggesting that the drug may be effective in treating some other types of cancer, such as colorectal cancer.
It would be interesting to replicate these results in other populations, but our results do not necessarily imply that the association observed with the disease in our family is causal. Instead, we suppose that either this cancer is simply more common in that population than in the general population or that these cases would not be diagnosed at all, if the diagnosis were dependent solely on family history which is the only definitive and absolute indicator available today. We are presently looking into other forms of diagnostic procedures such as magnetic resonance imaging to observe whether a cancer has manifested itself elsewhere in the family. It would be interesting to replicate this study comparing different populations across the country, but in the present it does not seem possible at this time.
The best way to determine the chances of developing cancer of the colon and rectum is to determine the individual's genotype by genetic testing. Many studies have tried to assess the probability of developing [colorectal cancer](https://www.withpower.com/clinical-trials/colorectal-cancer), but none have been as conclusive as they are not accurate in everyone. Most current studies are less than 95% accurate at predicting the chance of developing colorectal cancer. For example, there is only an 88.1% chances of being diagnosed with rectal cancer if one has only one APC mutated gene. This statistic does not take all of the other factors into account.
Age is the single most common risk factor for colorectal cancer. Although genetics have a minor, albeit important, role, there is no compelling data implicating the environment as the primary cause of colorectal cancer. However, other studies do suggest the possibility of environmental factors, such as aflatoxin, possibly playing a role in colorectal cancer. Colorectal cancer has a unique pattern of risk. Young men have a higher risk of development of colonic neoplastic lesions because of their increased number of colonocytes. On the other hand, elderly women are more likely than men to present with a curable disease. As a result, colorectal cancer is more likely in males than in females.
