Oncology of the gallbladder: symptoms, signs

Cancer of the gallbladder and bile duct (cholangiocellular carcinoma) in the incidence structure is usually assessed together. Cholangiocellular carcinoma (CCC) is a rare malignant tumor.

It is more often diagnosed in women. The risk of developing a tumor increases with age. Scientists associate such statistics with compaction and thickening of the gallbladder wall, as well as a decrease in its ability to contract. These changes are combined with signs of atherosclerotic lesions of the aorta.

Oncology of the gallbladder: symptoms, signs

Differential diagnosis of the disease is complicated by the nonspecificity of symptoms. Late referral of patients to an oncologist complicates treatment and increases the risk of complications.

What is the gallbladder

The gallbladder is an organ in the digestive system. Outwardly, in shape, it resembles a pear. Located on the lower (visceral) surface of the right lobe of the liver.

The gallbladder has a somewhat elongated shape. It distinguishes between the bottom (expanded part), body, neck (narrow part). The length of the bubble is 7-12 cm, the width at the bottom reaches 3-4 cm.

In research, an equally important value is the wall thickness. Normally, in an adult, it is no more than 4 mm (at rest - 2 mm, with contraction - 3.5 mm).

The structure of the gallbladder

Anatomically, the wall consists of serous, muscular and mucous membranes. The inner surface is lined with epithelial cells. In the area of ​​the neck is glandular tissue.

The gallbladder is a reservoir of bile that is synthesized in the liver. Due to the timely emptying of the bladder, bile enters the duodenum and takes part in the digestion of food.

In the composition of the secret, bile acids play an important role. They break down food elements into forms that are easily absorbed in various parts of the gastrointestinal tract (GIT). The secretion of bile activates pancreatic enzymes, triggers peristalsis (contractions) of the small intestine. The composition of bile affects the state of the gastrointestinal tract - maintains a healthy microflora, prevents the development of putrefactive processes.

The gallbladder serves as a reservoir for bile, which is necessary for normal digestion of food

The gallbladder is an indispensable element in the well-coordinated mechanism of digestion and absorption of food.

What is gallbladder cancer

Gallbladder cancer is a malignant tumor that develops from the tissues of the gallbladder. Among tumor neoplasms of the digestive system, it ranks fifth, according to some sources - 6th place.

The risk group includes patients with gallstone disease, polyps, gallbladder cysts, chronic infection (giardiasis, echinococcosis, H. pylori lesion), ulcerative colitis.

The risk increases with burdened heredity and prolonged contact with unfavorable factors. These include occupational hazards, contact with chemical carcinogens. The list continues with bad habits (alcohol abuse, smoking), eating disorders, eating food containing carcinogens.

Alcohol abuse and smoking increase the risk of gallbladder cancer

Classification of gallbladder cancer

The degeneration of healthy cells into malignant ones can begin in different layers of the wall and parts of the gallbladder.

In the first place in terms of prevalence is adenocarcinoma. The mutation occurs in the glandular tissue. According to various sources, such cases range from 80 to 85%.

One of the diagnostic methods is histological examination. This is the study of tissue taken from the affected organ under a microscope. Depending on the data obtained, they are distinguished:

• adenocarcinoma;
• squamous cell carcinoma;
• solid;
• skirrous;
• undifferentiated

To determine the type of cancer, histological examination is necessary

The most vulnerable to the malignant process is the bottom of the gallbladder - about 60% of tumors are registered with this localization.

Symptoms

The malignant process develops against the background of chronic diseases of the gallbladder and biliary tract, liver. The symptoms of gallbladder cancer are regarded as manifestations of sluggish processes. These patients may experience:

• weakness, fatigue;
• emotional lability;
• poor appetite;
• recurrent, nausea, vomiting;
• bloating;
• dull pain, heaviness in the right hypochondrium;
• subfebrile body temperature (for a long time 37.1-38.0 degrees Celsius);
• discoloration of the stool;
• weight loss

It is not easy to identify gallbladder cancer at an early stage: as a rule, such a disease manifests itself in the form of poor appetite, weakness, weight loss, rare pain

Gallbladder cancer can lead to impaired flow of bile. Added to clinical signs:

• paroxysmal pain in the right hypochondrium;
• yellowness of the skin and mucous membranes;
• tendency to increased bleeding;
• itching;
• chills;
• increased body temperature;
• changes in the color of urine and feces.

After signs of occlusion (blockage) of the biliary tract appear, the patient's condition worsens. Pain increases, fever appears, vomiting causes signs of dehydration. Ascitic fluid accumulates in the abdominal cavity.

If the biliary tract is blocked, the patient begins to feel worse: vomiting, fever appear, pain intensifies

A malignant tumor tends to spread to other organs. In such cases, the liver, duodenum and transverse colon can be affected. Less commonly, the omentum, stomach, pancreas are affected.

If you have symptoms that indicate a malfunction of the biliary tract and gallbladder, you should see a doctor. In the conditions of a specialized medical institution, examination and differential diagnosis with various diseases are carried out.

Diagnostics

The nonspecificity of symptoms, involvement of the bile ducts, liver complicates the diagnosis. Primary referral most often occurs to a gastroenterologist or therapist. An important stage of the examination is the collection of anamnesis and patient complaints. The doctor finds out the living conditions, work, dietary habits, the presence of chronic diseases, the dynamics of alarming symptoms. The examination includes the identification of changes in the color of the skin and mucous membranes, auscultation of the lungs, palpation of the abdominal organs, lymph nodes.

When signs of a disease are detected, a comprehensive diagnosis is prescribed, consisting of various procedures and analyzes. Early diagnosis is facilitated by the passage of medical examination.

The examination begins with laboratory diagnostics.

For an accurate diagnosis, a comprehensive diagnosis is required

The patient is prescribed a general analysis of blood, urine, biochemical analysis, coprogram (study of the physical and chemical properties of feces and pathological inclusions). Even in the absence of jaundice, tests help to identify pathology.

A general blood test shows an increase in the erythrocyte sedimentation rate, changes in the leukocyte formula, anemia.

Biochemical analysis reveals deviations from the norm of the indicator of protein, total bilirubin and its fractions. Liver enzymes ALT, AST, alkaline phosphatase increase. With the involvement of the kidneys in the process, the indicators of urea and creatinine increase.

A coagulogram reflects imbalances between the coagulation and anticoagulation systems of the blood.

A biochemical blood test will help identify deviations from the norm of various indicators, which is characteristic of the oncological process in the body

To exclude viral hepatitis, AIDS, tests are prescribed for markers of viral hepatitis B and C, antibodies to HIV infection.

Diagnosis of oncological diseases includes screening with the determination of tumor markers. These are substances that are formed during the life of tumor cells or during the response of the body's immune system.

In cancer of the gallbladder, tumor markers are determined: CEA (cancer embryonic antigen), AFP (alpha-fetoprotein), CA 19-9 (tumor-associated antigen 19-9). The doctor can prescribe tests for the level of tumor markers in dynamics. Exceeding the tolerance limit is not specific only to gallbladder cancer. Therefore, laboratory parameters are assessed in conjunction with clinical symptoms, instrumental methods and histological studies.

The doctor always prescribes an analysis for the level of tumor markers in the blood.

Hardware diagnostics

Diagnosis of malignant processes in the gallbladder is difficult for the following reasons:

• symptoms may indicate chronic infections, benign processes of the cholangiocellular region;
• differential diagnosis is necessary with diseases of the liver, pancreas, stomach, metastatic lesions in oncological processes of other localization;
• the anatomical location of the gallbladder makes it difficult to palpate and carry out a number of instrumental methods.

Diagnosis of gallbladder cancer is usually difficult, since it is necessary to distinguish such a pathology from other diseases also associated with the liver, stomach, etc.

Often, a malignant lesion is detected during a histological examination of a surgically removed gallbladder.

Ultrasound

The essence of the study is to create an image of an organ by scanning it with ultrasonic waves. Determination of the size, wall thickness, contents and shape of the gallbladder is carried out. These studies are compared with the indicators accepted as the norm. As a rule, not only the bladder and bile ducts are scanned, but also the liver.

When examining the gallbladder, the pathological process may indicate:

• thickening of the wall;
• inclusions visualized in the bladder cavity (calculi, pus, bile, more dense formations);
• tumor mass is determined at the site of the gallbladder

Ultrasound of the gallbladder

The detection of a tumor by classical methods of ultrasound diagnostics is accompanied by difficulties. Therefore, more sophisticated technologies are used in the research process. Three-dimensional ultrasound imaging in angiography mode has several advantages:

• allows you to refuse intravenous administration of a contrast agent and avoid possible complications (anaphylactic shock);
• gives a more accurate result;
• reveals the vascular pattern of tumor formation.

The results obtained are not a basis for a diagnosis. Interpretation of data is considered in conjunction with other studies.

Ultrasound does not always allow you to accurately make such a diagnosis.

Tomography

Computed tomography is a method of layer-by-layer examination of internal organs using X-rays.

The computer program sets the direction of the beam, covering various sections, determines the "step" of the study (from mm to cm). The resulting information is printed as images. When diagnosing a malignant lesion of the gallbladder, CT is used in the initial examination, as well as when specifying the stage of the process.

CT scan reveals an increase in lymph nodes, the spread of the process to the liver, metastasis to other organs. More accurate information is provided by a CT scan with the introduction of a contrast agent. The technique is prescribed separately, and more often in conjunction with other studies.

CT scan of the gallbladder

MRI is a method of creating detailed images of an organ using radio frequency electromagnetic fields. The value of the study consists in obtaining images with high contrast between different soft tissues, the ability to examine different sections. A positive difference from the previous method is the absence of ionizing radiation and associated risks and restrictions.

Magnetic resonance cholangiopancreatography (MRCP) is a specialized method for studying the pathology of the gallbladder and biliary tract. It is the most accurate screening tool. The non-invasiveness of the method is an added advantage.

Cholangiography

Cholangiography is a method of examining the bile ducts by X-ray radiation after the administration of a contrast agent. Imaging can help clarify the cause of the bile duct blockage. The contrast is injected directly into the study area. This technique is carried out during the operation.

Endoscopic retrograde cholangiopancreatography is performed using a combination of endoscopic and radiographic techniques. In the descending part of the duodenum is the Vater nipple. Through it, bile and pancreatic secretions enter the small intestine. With the help of an endoscope, the nipple of Vater is cannulated and a contrast agent is injected into it. The result is a series of images. The method is invasive, and is an option for clarifying the diagnosis and carrying out medical procedures.

Cholangiography

Percutaneous transhepatic cholangiography is performed under ultrasound guidance under aseptic conditions. A puncture is achieved with a special needle and a cannula is inserted into the bile ducts. The introduction of contrast allows you to visualize the area of ​​interest. The method is often a step in the operation. Potential complications: bleeding, infection.

Laparoscopy

Laparoscopy refers to minimally invasive surgery. The procedure is performed using an endoscopic technique, which is inserted through small incisions into the abdominal cavity. Previously, carbon dioxide is injected into the abdominal cavity. The laparoscope is equipped with a light source, video camera and fiber optics. The camcorder enlarges the image and transmits it to the monitor screen. Manipulators inserted through separate incisions allow the surgeon to view organs and perform surgical manipulations.

Benefits of laparoscopic surgery:

• minimal trauma;
• decrease in intraoperative blood loss;
• minimization of adhesions, infectious complications;
• fast tissue regeneration after surgery.

Possible laparoscopy for diagnostic purposes

Laparoscopy is performed under general anesthesia.

Manipulation is used as a diagnostic, therapeutic and makes it possible to conduct targeted biopsy.

A biopsy is a mandatory diagnostic procedure when examining a patient for the presence of a malignant process. Intravital tissue sampling is performed for cytological examination. With the help of a microscope, pathological changes in the structure of the cellular composition are established.

Mandatory biopsy - tissue sampling for cytological examination

Determination of the stage of development

Treatment is prescribed after examination and staging of the process according to the TNM classification.

The system is based on alphanumeric encryption of the dynamics of tumor development:

• T is the state of the primary tumor;
• N - changes in regional lymph nodes;
• M - presence of distant metastases.

Treatment is prescribed after a complete examination, an accurate diagnosis, and determination of the stage of the cancer.

The set of signs allows you to determine the stage of the malignant process.

Stage 1 characterized as the onset of the disease. The primary tumor does not extend beyond the inner layer of the gallbladder wall. Regional lymph nodes are not involved, there are no metastases to other organs.

Stage 2 indicates that the primary tumor has spread to the muscle layer and connective tissue. No invasion outside the organ was detected.

Stage 3 - the spread of the primary tumor outside the bladder. In the case of "A" the nearby lymph nodes are intact, in the case of "B" they are involved in the process.

Stage 4 characterized by invasion of the liver or other organs.

The last, 4th stage of gallbladder cancer, is characterized by the presence of metastases in the liver and other organs

Stage "A" - involvement of the vascular bundle of the liver (portal vein and hepatic artery) or two or more organs. Stage B is defined by the presence or absence of metastases and regional lymph node involvement.

Treatment

The treatment tactics are determined by the stage of the process, the initial state of the patient, and the structure of the tumor. It can be invasive (surgical) or conservative.

Surgical interventions, in turn, are divided into radical and palliative.

Radical surgery - extended cholecystectomy. In the postoperative period, chemotherapy and / or radiation therapy is performed.

After cholecystectomy, chemotherapy and / or radiation therapy is indicated

Palliative (symptomatic) surgery is designed to improve the patient's quality of life, but cannot stop the disease.

Chemotherapy is a treatment that uses drugs that stop tumor growth or damage cells. The main goals of chemotherapy are:

• preparatory period before surgery;
• prevention of metastasis and relapses after surgical treatment;
• combined use with other types of therapy;
• method of treatment for inoperable cases.

Chemotherapy can be given before surgery to stop the tumor from developing and literally kill it.

The method has side reactions: nausea, vomiting, weakness, appetite and sleep disorders.

Radiation therapy uses ionizing radiation to damage tumor cells. Modern devices are equipped in such a way that the shape of the irradiated volume is as close as possible to the shape of the tumor. This protects healthy tissue from ionizing radiation.

All methods can be combined or applied sequentially.

Radiation therapy may also be given before surgery to stop the spread of the tumor.

The success of any treatment tactics depends on the psychological state of the patient, his desire to cooperate with medical specialists. Any disease, especially oncological, makes a person feel shock, causes fear of death, uncertainty, helplessness, dependence. In the course of treatment, even the most persistent and strong-willed people may doubt themselves, their strengths. Without support from the outside, such a burden is very difficult to endure. It is wrong to think that only close people can offer help.

The complex of treatment for cancer patients includes work with a medical psychologist who accompanies the process from the very beginning. He, too, initially diagnoses the patient's mental status and chooses effective ways to work with him and his relatives and friends.

Treatment of gallbladder cancer must be accompanied by work with a psychologist

Often, patients turn to traditional medicine recipes and self-medicate. Herbal medicine involves the use of medicines obtained from natural raw materials.

It is important to understand that herbal medicine is a clinical discipline and part of the healing process. The decision to use medicinal herbs must be justified, as should any other method. The selection of prescriptions is carried out strictly individually and takes into account the characteristics of the malignant process, the treatment being carried out, and the prognosis.

Rehabilitation and dispensary observation after radical operations and therapeutic methods involves monitoring the patient during the first year with regularity every 3 months, the second year in 6 months. For the next five years, examination is mandatory once a year. Observation includes examination by an oncologist, laboratory and physical methods.

Cancer patients must regularly undergo a complete examination of the body.

Patient survival data indicate an association between early medical care seeking and improved prognosis. With initial diagnosis and treatment, 80% of patients survive within five years. This figure when applied at the second stage of the process is significantly lower and amounts to 25%.

Terminal states

In the course of fighting the disease, the body gradually depletes its resources.

Malignant processes affect the activity of the central and peripheral nervous system. Consciousness is gradually depressed. The patient lies with his eyes closed, does not respond to questions. Liver damage is accompanied by a hepatic coma - a complete lack of consciousness.

Depression of the functions of the nervous system negatively affects blood circulation and respiration.

Blood circulation in the organs is impaired. The skin becomes gray, cold clammy sweat appears. The limbs feel cold to the touch. Blood pressure decreases, heart rhythm is disturbed. The pulse becomes weak, threadlike.

The terminal stage is often accompanied by depression of consciousness, impaired circulation, lowering blood pressure

Shortness of breath (difficulty inhaling or exhaling) is observed, breathing becomes more frequent, and a pathological rhythm appears. The formation of urine is impaired. Specific symptoms appear: nausea, vomiting, bloating, absence of stool.

Liver damage is accompanied by a blood clotting disorder. Patients develop complications in the form of gastrointestinal bleeding, bleeding gums.

States bordering between life and death are called terminal.

Possible gastrointestinal bleeding in patients with stage 4 gallbladder cancer

There are four such states

State	Description
Predagonia	It is characterized by a pronounced dysfunction of the central nervous system, blood circulation, respiration. Consciousness is depressed, maybe to a coma. Breathing is shallow, frequent or infrequent. The pulse is weak or is detected only on the carotid arteries.
Terminal pause	Against the background of frequent superficial respiratory movements, respiratory arrest (apnea) develops, which can last from 1 to 4 minutes. Then breathing is restored on its own. The process is due to the "shutdown" of the functions of the cerebral cortex and the "activation" of the reserve respiratory center in the stem structures.
Agony	The classic version involves a short-term improvement in the state of the dying person. Not always observed.
Clinical death	The contraction of the heart stops, as a result of which blood circulation is maintained. Consciousness and breathing are not detected, there is no pulse in the carotid arteries. Pupils are dilated, do not react to light.

There are several types of terminal states.

Clinical death lasts an average of 5-6 minutes. Then irreversible changes occur, which are called biological death.

Prophylaxis

Prevention is viewed as a way to avoid the influence of adverse factors on human health. This article is about the gallbladder. But it would be a mistake to think that it is enough just to eat right.

Human life is an endless process of interaction with the external environment, society, nature, modern technologies. All this together has an impact on his well-being: physical, mental, social.

Taking responsibility for your life processes is the best way to stay healthy and happy for as long as possible.

Valentina, g. Moscow

“I want to tell my story. My sister complained all her life of pain on the right side. Usually attacks occurred after physical exertion or spicy and fatty foods. Saw "No-shpu", "Allohol", brewed choleretic herbs. The pain was gone, there were no other signs.

The first time they were alarmed was when an attack of severe pain developed in the garden, so they even had to call an ambulance. The hospital examined. The doctor said that there are signs of inflammation, several stones in the bladder, advised to remove them. He said that complications may develop with age: jaundice, inflammation of the liver. My sister refused, decided to take pills, follow a diet. And again it went the same way - it hurts, then everything is fine. After some time, she began to notice that she was quickly tired, there was no mood, and she began to lose weight. Eat, vomiting begins. We noticed that yellowness of the skin appeared.

I was already retired. She underwent an ultrasound scan, passed the tests, and was sent to an oncologist. After several more examinations, she was diagnosed with gallbladder cancer. The oncologist said that the stage is advanced and that it is only possible to alleviate the condition by installing a tube for the outflow of bile. They began to prepare for the operation, but the condition worsened greatly, so they did not operate. After 1.5 months, my sister died. She was already unconscious.

It turns out that the doctors say the truth - since something went wrong, you need to pay attention. It seems that it’s okay, but you can overlook life ”.

It is very important to see a doctor right away if you experience prolonged discomfort - do not try to heal yourself

Svetlana, g. Kaluga

“As a child, my mother suffered from hepatitis and often complained of pain. He will work in an inclined way or eat something fatty or spicy - and immediately bad. She worked at the plant and underwent medical examinations. Ultrasound revealed stones in the gallbladder, sent to the surgeon. On the advice of a doctor, we decided to operate endoscopically so that there were no complications. The bubble was removed. The biopsy showed cancer. After discharge, they began to be examined. No nodes were found in other organs. Completed a course of chemotherapy. Of course it's hard. But we are glad that we listened to the doctor's advice, and my mother went to the operation. Now she is getting much better, and I am sure that she will live for many more years. "

Timely access to a doctor is the key to a healthy and long life

Conclusion

The clinical manifestations of gallbladder cancer are nonspecific and can be interpreted as an inflammatory process. Often, the tumor is detected late, already during the period of its spread outside the organ and the development of complications. To determine the tactics of treatment, a comprehensive examination is required. It includes laboratory, hardware, clinical and cytological diagnostics. Based on the research carried out, the stage of the process is determined.

The doctor develops treatment tactics in accordance with the nature of the malignant tumor (histological data, the possibility surgical access), the initial data of the patient (age, concomitant diseases, general condition at the time of examination). There is surgical and conservative treatment. Most often they are assigned in combination.

First, conservative treatment is prescribed, and if it does not work, surgery

The prognosis of the disease depends on how early the tumor was detected.

Prevention of diseases, malignant processes of the gallbladder depends on the lifestyle, food behavior, timely access to medical specialists and respect for age-related changes organism.
