Highly differentiated adenocarcinoma of the colon refers to a number of diseases. Namely, tumors of the colon, cecum, sigmoid and rectum, as well as a tumor of the anal canal.

The tumor occurs in the glandular layer of intestinal tissue. The cells of highly differentiated adenocarcinoma resemble the tissue in which the tumor developed in their structure. This allows for quick diagnosis of the problem, and due to the low aggressiveness of highly differentiated tumors, there is the opportunity and time to choose the optimal treatment method. As a rule, the causes of highly differentiated adenocarcinoma of the colon are common to all possible tumor locations in the colon. In the first place is the diet: low fiber content in the diet, excess of flour, fatty and spicy foods. In addition, frequent or prolonged constipation, all sorts of pathological processes in the colon, such as colitis, ulcers, polyps, play an important role in the possibility of developing adenocarcinoma of the colon. Long-term contacts with various toxic substances have a certain effect, with the negative effect of asbestos being especially highlighted. As in other cases, the development of the disease can be influenced by nervous stress, heredity, mechanical damage, age-related factors and viral infections.

Where does it hurt?

Well-differentiated adenocarcinoma of the cecum

Various colon tumors are currently the focus of close attention from scientists around the world. The colon is now responsible for most oncological diseases. Most symptoms and manifestations are relatively common for all colon tumors, but in some cases there are specific features related to location.

In particular, highly differentiated adenocarcinoma is difficult in that it cannot be detected during a standard preventive examination. As a highly differentiated tumor, it has a low degree of aggressiveness, cell polymorphism is weakly expressed, and the tumor rarely metastasizes.

Adenocarcinoma of the cecum poses a certain danger because the inguinal lymph nodes and liver are located nearby.

Highly differentiated adenocarcinoma of the cecum occurs with approximately equal frequency in men and women, the age of occurrence fluctuates between 50 and 60 years. Although there is a sad tendency for the age threshold to decrease, and this disease increasingly affects young people. The main symptoms are the same as for almost any other intestinal tumor - weakness, low hemoglobin, sudden weight loss, suspicious discharge with feces, discomfort in the lower abdomen, bloating, and disruption of the bowel movement. The causes of adenocarcinoma of the cecum include the same factors that generally affect the possibility of developing not only an intestinal tumor, but any other tumor. These include poor heredity, unfavorable environmental conditions, and work with carcinogenic substances.

Special factors include two such important aspects as the consumption of natural fibers (cellulose) in food, as well as the possibility of the formation of non-malignant phenomena such as polyps in the area of the cecum. The latter, in turn, have the ability to quite often turn into malignant ones. It is quite difficult to talk about the prevention of such diseases, therefore it will be more reliable to be examined by a doctor regularly once every six months or a year. Since this cancer is quite successfully cured if detected in time.

Well-differentiated adenocarcinoma of the sigmoid colon

Sigmoid adenocarcinoma belongs to a group of oncological diseases called colon cancer. Colon cancer is the most pressing problem in modern oncology. Along with the active development of this disease, the ability of medicine to study it and develop methods to combat it is also growing.

Highly differentiated adenocarcinoma of the sigmoid colon is a rather slow-growing tumor that is not prone to actively metastasizing. However, it is quite dangerous. In particular, the sigmoid colon itself has bends, so a tumor developing in it can be detected too late. It is also important that in the early stages of development, adenocarcinoma of the sigmoid colon does not give symptoms that would directly indicate the development of a pathological process in the intestine. At first, the patient feels general malaise, weakness, nausea, fatigue. A little later, pain and heaviness in the lower abdomen, distortion of eating habits, exhaustion, and pale skin may occur. At fairly late stages, when the tumor has reached such a size that it creates mechanical obstacles, difficulty with defecation is observed, inclusions such as blood or pus appear in the feces.

The main causes of the development of highly differentiated adenocarcinoma of the sigmoid colon are considered to be a lack of fiber in the diet, an excess of substances that irritate the intestines, and inflammatory processes in the intestines.

Well differentiated adenocarcinoma of the rectum

Today, the problem of rectal cancer is the most important among the oncological problems of the twenty-first century. The most common is rectal adenocarcinoma. That is, the development of a cancerous tumor from the glandular epithelium of the rectum. Due to the great relevance of this disease, special attention is paid not only to the development of modern progressive methods of its treatment, but also to the study of possible causes of its occurrence, as well as a more accurate forecast of the development of rectal adenocarcinoma. Although no visible breakthroughs in the treatment method have been found against the background of the general development of oncology, more accurate causes of rectal cancer have been identified. As in the case of many other types of tumors, an important role is played by the general background, which includes genetics, general health, and the environment. But in the case of rectal adenocarcinoma, a special role is played by the interaction of genetic predisposition and environmental factors, and only in some cases are the cause directly genetic mutations. The main risk group for this disease is people over fifty years of age. The main danger of the disease is that it begins to show pronounced symptoms at fairly late stages, when the prognosis of even the most successful treatment is already quite disappointing. The main symptoms of the disease are aching pain in the abdomen, the appearance of blood, mucus or even pus in the stool, obvious pallor of the patient's skin, active weight loss, bloating and difficulty with defecation. As for the prognosis, the critical period is considered to be five years after the onset of the disease. If the patient has lived through this period, then in the future he has a fairly high chance of living for many more years. But the mortality rate during this five-year period is quite high. Therefore, the best prevention of rectal adenocarcinoma is regular preventive examination. Such examination can include an analysis of feces for internal blood, and it is also recommended to conduct a colonoscopy once a year for people over fifty.

Diagnosis of well-differentiated adenocarcinoma of the colon

Correct diagnosis of any disease largely determines the outcome of its treatment. In such complex cases as oncological processes, studies are always carried out that duplicate each other to accurately determine all possible angles of the problem.

In any case, diagnostics begins with determining the symptoms. It rarely happens that a tumor is discovered during a random examination. Most often, patients come with one or another complaint. Usually, the doctor independently examines the patient. If there is even the slightest reason to doubt the accuracy of the diagnosis, then additional research methods are prescribed. Such methods most often include ultrasound diagnostics, blood tests for specific proteins, certain probing methods, tissue sampling for cytological and histological analysis.

In some cases, a decision is made to simply observe the development of the disease. If we are talking about a highly differentiated adenocarcinoma, which grows slowly and metastasizes infrequently, then treatment may be prescribed to contain the development of the disease. And observing the results of such treatment can also tell a lot about the disease itself. In any case, only an oncologist can conclude that this is a highly differentiated adenocarcinoma after conducting a series of studies and observations. But still, the main source of information for a correct diagnosis will be histological and cytological analysis, which will determine the condition of the cells, their degree of differentiation and modification in comparison with the cells of the tissue of the organ that formed the tumor.

Treatment of well-differentiated adenocarcinoma of the colon

Highly differentiated adenocarcinoma is a type of oncogenic tumor that is formed from glandular epithelial cells, but from the point of view of histological analysis, these cells do not differ greatly in structure and function from other cells of the organ tissue where the tumor formed. In the vast majority of cases, highly differentiated tumors grow slowly and do not metastasize. However, their treatment cannot be postponed. Firstly, because cell differentiation may change (the level of cell differentiation will decrease), and secondly, because the rate and danger of tumor development are influenced by many factors, and not just the results of histological analysis.

Among all possible methods of treating highly differentiated adenocarcinoma, the most unifying and reliable is the method of surgical intervention. It is quite rarely the only one. But most often there is no escape from it. Along with surgical methods of treating highly differentiated adenocarcinoma. Radiation therapy, chemotherapy, hormonal therapy (in the case of hormone-dependent tumors) are also widely used. But it should be noted that auxiliary methods in different cases have different degrees of effectiveness (depending on the organ of origin, stage of development).

Since surgical methods are the main tool for combating various ailments, the methods of operative surgery are significantly improved. Some operations in the abdominal cavity are carried out without making incisions, using micromanipulators, mini-cameras for visual control.

Prevention of well-differentiated adenocarcinoma of the colon

Oncological diseases are among those that are most frightening and least controllable. However, today many factors of influence that with a high degree of probability cause certain types of cancer have already been studied. Highly differentiated adenocarcinoma can occur in any organ that contains glandular epithelium. Therefore, the prevention itself may be different for different organs. But there are absolutely similar risk factors for all cases. These include all bad habits. Smoking, for example, greatly affects not only the development of lung cancer, but also significantly worsens the picture for cervical cancer, alcohol increases the likelihood of developing adenocarcinoma of the stomach and prostate gland. Healthy eating also plays an important role. The presence of a sufficient amount of fiber in the diet significantly reduces the likelihood of developing all types of bowel cancer. But in addition, it is important to pay attention to the quality of the products consumed. A large number of synthetic components, carcinogenic substances, flavor enhancers significantly increase the risk of developing a particular oncological problem. Genetic predisposition plays an important role. Therefore, if it is known that there were certain cases of cancer in the family, then it is possible to conduct a genetic analysis for a predisposition to a particular type of cancer, and then study the situation more closely. In any case, it is regular screening of all kinds that becomes the key to health. There are a number of precancerous conditions, such as polyps, hyperplasia, dysplasia of tissues of certain organs. If they are detected in a timely manner, it is possible to successfully prevent the development of a cancerous tumor. And even if highly differentiated adenocarcinoma was detected during regular examinations, it is characterized by slow growth, and it is possible to select the most suitable treatment method to rid the patient of this problem forever.

Prognosis of well-differentiated adenocarcinoma of the colon

The prognosis of any oncological disease depends on a number of factors. In most cases, the decisive factors are such tumor characteristics as its size, histological level of cell differentiation, stage at which the patient sought help, as well as the general condition of the body and a number of concomitant diseases. In the case of highly differentiated adenocarcinoma, we are talking about a high level of cell differentiation, therefore such a tumor most often has a good prognosis, since the growth of a highly differentiated tumor is slow, and metastasis begins at fairly late stages. But an important aspect is the correct timely diagnosis and the speed of solving this problem.

Unfortunately, the symptoms of highly differentiated adenocarcinoma are not specific, so patients often consult a doctor at fairly late stages of development. Sometimes such diseases can be discovered by chance - during other studies or surgery. Of course, adenocarcinomas of different organs have different incidence rates, so some of them, such as adenocarcinoma of the colon, uterus, prostate, are given special attention and more frequent screening is carried out, which increases the likelihood of detecting the disease at early stages and significantly improves treatment prognosis.

If the tumor was removed at an early stage, before it began to metastasize, before other organs and tissues were affected, the prognosis is overwhelmingly positive. An important indicator is the so-called five-year survival rate. If the patient has successfully survived five years after the tumor was detected and removed, then in the future we can say that the probability of relapses or negative consequences is very low. Good prognosis can also be spoken of if there are no aggravating factors. For example, the presence of the human papillomavirus or herpes in the body can provoke the development of adenocarcinoma, working with carcinogenic substances also worsens the situation, the presence of bad habits negatively affects the body as a whole. Special attention should be paid to genetic predisposition to a particular type of oncological diseases. If a person is at risk, this undoubtedly worsens the prognosis. If during or immediately after the treatment period the patient continues to contact with negative factors, does not limit their impact, then this undoubtedly leads to negative prognosis for recovery. Since even highly differentiated adenocarcinoma can develop rapidly and cell differentiation can decrease, which makes the tumor aggressive and can significantly complicate the fight against metastases.

Colon adenocarcinoma is one of the most acute problems of oncology of our century. The frequency of its occurrence is steadily increasing. The main supposed causes of occurrence include lack of coarse fiber in food. Heredity and ecology also play an important role. There are many innovative methods of treatment and diagnostics of colon tumors, but speaking about prognosis, it should be said that the attitude of patients plays an important role. The stage of the disease development at which the patient consulted a doctor has always been of great importance. Often, a number of neoplasms can be detected during preventive examinations. But a proctologist is rarely on the list of doctors to whom people go for prevention. Often people seek help when adenocarcinoma has already reached serious proportions. Highly differentiated adenocarcinoma of the colon has no specific symptoms, general weakness, weight loss are unlikely to lead the patient not only to a proctologist, but to any doctor at all. Highly differentiated adenocarcinoma, although slowly, grows. And at the stage when patients find blood or pus in the stool, the general prognosis for the disease is not very good. Good prognosis is generally worth talking about in cases where the tumor is very small and has not damaged tissues and organs. In this case, its removal is easily tolerated, and the likelihood of relapse is very small, in other cases, the prognosis is worse, the larger the tumor size. Since resection of a fairly large part of the intestine is often required, A in order to completely remove all affected cells to avoid relapse. It is also important to note that, unlike other types of adenocarcinomas, highly differentiated adenocarcinoma of the colon is quite poorly amenable to chemical and radiation therapy, so surgical intervention remains the most effective and rational way to combat the disease.
