Various Recent Advances in Liver Cancer Treatment Methods

Various Recent Advances in Liver Cancer Treatment Methods
Various Recent Advances in Liver Cancer Treatment Methods - Liver cancer is a common type of cancer. Until now, there have only been a number of effective ways to prevent or treat liver cancer. However, many efforts have been made in research on new ways to prevent and treat liver cancer. Scientists work relentlessly to find the cause of liver cancer for prevention better, and doctors work to improve treatment in patients. There has been great progress in liver cancer research.


Treatment of liver cancer


Now there are many ways to treat liver cancer:
  • Life resection: Surgery to remove all or part of the liver
  • Liver transplant: Change the liver
  • Arterial embolization: Seals or blocks blood vessels to the tumor
  • Radiofrequency ablation: A form of tumor ablation (destruction without removing a tumor) that uses heat to destroy tumor cells
  • Alcohol injection: Entering alcohol which is toxic to the tumor through needles. This is used in small tumors
  • Kriotherapy: A form of therapy that uses cold temperatures to kill cancer cells
  • Chemotherapy: Using chemicals to treat cancer
  • Biological therapy: Use agents such as viruses to kill cancer cells
  • Target therapy
  • Care support

Doctors also learn how to make liver cancer more easily removed by shrinking it before surgery. There are already studies of therapies given before surgery, including targeted therapy, chemotherapy, ablation, embolization, and radiation therapy. Preliminary results have been promising but only seen in a small number of patients.

Treatment for cancer also means preventing cancer from recurring after surgery. Most studies that have so far used chemotherapy or chemoembolization after surgery have not proven effective. However, there are new drugs that are promising and perhaps more effective. Some of the drugs studied include the targeted drug sorafenib (Nexavar) and menatetrenone, drugs that are chemically similar to vitamin K. Some positive results have also been seen with radioembolization, but this needs confirmation in a larger study.

Surgery has become the main treatment for liver cancer. New techniques developed to make both partial hepatectomy (lifting parts of the liver) and liver transplantation safer and more effective.


Laparoscopic surgery

In laparoscopic surgery, several small incisions are made in the abdomen. The doctor will insert a special thin long tube to see and cut off the part of liver cancer. Does not require a large incision in the abdomen, which means that there is at least blood loss, less pain after surgery, and faster recovery.

At present, laparoscopic surgery is still considered experimental and is used primarily for small tumors in certain parts of the liver which can be easily achieved through a laparoscope.


Liver transplant

Liver transplant patients must meet many strict criteria. For this reason, only a few patients are liver transplant candidates. Some doctors are now looking for ways to expand these criteria. One study examined the replacement of the liver with slightly larger but still healthy.

Liver transplantation is a major surgery and there is a risk of potentially life-threatening complications. It is estimated that about 1 in every 30 people will die during the procedure and up to 1 in 10 people will die at some point in the following year after surgery.


Liver transplantation may be suitable for you if:
  • You only have a single tumor less than 5cm in diameter
  • You have three or fewer small tumors, each less than 3cm
  • You have responded very well to other treatments, with no evidence of tumor growth for six months

Radiation therapy


The biggest concern for radiation therapy is that it will damage healthy tissue. The researchers are now working to focus on radiation therapy against cancer, so that the surrounding healthy tissue is not affected. One approach that is learned is called brachytherapy. In this treatment, a thin tube called a catheter is placed in the tumor and then the pellets that emit radiation are inserted into the catheter for a short time. After treatment, both pellets and catheters are removed. This allows radiation to be targeted at cancers that are less harmful to the normal liver.


Target therapy


New drugs are being developed that work differently from standard chemotherapy drugs. Newer drugs target certain parts of cancer cells or the surrounding area.

Therapy focuses on blood vessels that supply blood for tumors. The tumor grows by getting a blood supply. A new type of drug, sorafenib (Nexavar), has been used in several types of liver cancer that cannot be removed surgically. This drug works by preventing the growth of new blood vessels in the tumor. Sorafenib is now being studied for use early, such as after surgery or trans-arterial chemoembolization (TACE). Researchers also study whether combining it with chemotherapy can make it more effective.

Regorafenib (Stivarga®) is another targeted and promising drug in treating liver cancer.


Chemotherapy

Chemotherapy combined with other treatments is being tested in clinical trials. A small number of tumors respond to chemotherapy. However, it has not been shown to extend the survival of patients.

Chemotherapy drugs, such as oxaliplatin, capecitabine, gemcitabine, and docetaxel, are being tested. Oxaliplatin has shown promising results in early studies when combined with doxorubicin. Oxaliplatin combined with gemcitabine and drugs from cetuximab (Erbitux®) targeted therapy have proven effective.


Virus therapy

The latest approach to treatment is the use of a virus, known as JX-594. This is the same virus used to make the smallpox vaccine, but has been changed to only infect abnormal cancer cells and cells. In this treatment, a solution containing the virus is injected into liver cancer. The virus will then enter the cancer cell, which causes these cells to die, or pushes the immune system to attack cells. This treatment has been tested in patients who do not respond well to other treatments and appear promising.


Prevention of liver cancer

An ounce of prevention is worth a pound of cure. It is more effective to stop cancer before it starts. Vaccination and better treatment for liver cancer can prevent about half of liver cancer cases worldwide. Researchers are studying ways to prevent hepatitis C or treat hepatitis infections before they cause liver cancer. Treatment for chronic hepatitis also shows progress.


Screening

Scientists recommend using blood tests to detect liver cancer in the early stages rather than using AFP and ultrasound. One promising test is called DKK1.


Determine the risk of recurrence after surgery

After liver surgery, the main concern for everyone involved is the risk of recurrent cancer, which means the cancer will come back. Knowing a person's risk of recurrent cancer can help doctors determine the next follow-up or one of the additional treatments to reduce this risk.

The researchers are studying cells in surgery as samples. They see cell gene patterns near the tumor and are able to predict who has high risk. These initial findings need to be confirmed in other studies before widespread use.

In conclusion, there has been great progress in the field of liver cancer. Prospects are better for people who do liver transplants. Overall, around 75 out of 100 people survive for 5 years or more after this type of surgery.

Method of Diagnosis in Patients with Liver Cancer

Method of Diagnosis in Patients with Liver Cancer
Method of Diagnosis in Patients with Liver Cancer - Liver cancer is part of the high incidence of disease, but also a big loss! Cancer symptoms and signs of examination for the significance of some signals sent through the body to identify and determine whether cancer is. After you find yourself in a physical disorder in everyday life, you need to go to the hospital for a check-up.

Early detection of liver cancer after treatment, 5-year survival rate can reach 70%, whereas in patients with advanced only half the chance to survive. Therefore, understanding the diagnosis of liver cancer is very important, early detection and early diagnosis are an important part of treatment.


Then what is the method of diagnosing liver cancer?


1. Ultrasound examination: a diagnosis of a valuable liver tumor to show tumor size, shape, and diagnosis rate of up to 84%, can be found in a diameter of 2cm or a smaller lesion. This is a non-invasive examination method, harmless to the human body. When losing weight, fatigue, heartache and other symptoms of liver cancer are suspected, this examination can be done.

2, CT Scan: High-resolution CT, about 1.0cm in diameter can be detected in early liver cancer, the rate of diagnosis of liver cancer is up to 90%, but they are expensive. So don't apply it universally.

3, MRI examination: to increase the rate of detection of small hepatocellular carcinoma, liver and liver cancer while local hyperplastic nodules, liver adenoma and other identification of assistance are greater, can serve as an important complement to CT examination.

4, AFP: Clinically, alpha-fetoprotein is commonly used in the diagnosis of liver cancer, this method is simple and practical

5, selective celiac artery or arterial hepatic angiography: cancerous blood vessels, sometimes can show a diameter of 0.5-1cm of the disease, the level of diagnostic accuracy up to 90%. To determine the location of lesions, size and distribution, especially for the diagnosis of small liver cancer is the best variety of examination methods.

 
Effective treatment of cancer early diagnosis of liver is a prerequisite condition. With the advancement of medical technology, a comprehensive treatment model that continues to use the therapeutic effects of early HCCs increases significantly. Treatment of liver cancer is primarily to see the deterioration of the patient's condition, to take medication, physically and psychologically, etc. These factors can be regarding the treatment of patients with liver cancer and the time of survival, of course, if at the beginning to take reasonable and effective treatment options, the possibility of long-term survival from the initial HCC is still very large.

Initial Symptoms that Arise in Patients with Liver Cancer

Initial Symptoms that Arise in Patients with Liver Cancer
Initial Symptoms that Arise in Patients with Liver Cancer - Liver cancer is mainly in the following situations: Working days, eating more fruits and vegetables, less busy with work and entertainment at night, without rest, benches are always boiling and so on. It will appear that liver cancer is actually not far from us.

When symptoms of liver cancer appear, they are often misdiagnosed as other diseases, may be mistaken for abdominal pain, bloating, unwillingness to eat, and some people go to the stomach, it is wrong for cholecystitis. When physical discomfort, the need to carefully distinguish physical symptoms, go to the hospital to make a detailed diagnosis of liver cancer, reduce the possibility of misdiagnosis.

 
Guangzhou Modern Cancer Hospital experts show that the very typical performance of early liver cancer is often easily overlooked. The following symptoms are for reference:

1. Appetite decreases significantly: fullness of the stomach, indigestion, and sometimes nausea and vomiting. If you suspect that liver problems, ultrasound examination of the liver can be done on body tissues without side effects.

2. Right upper quadrant pain: the liver may have persistent or intermittent pain, and sometimes metastasis and pain are intensified. Heartache requires a CT scan, you can clearly show the size of the heart, number, shape, location, boundary, level of tumor blood supply, and the relationship with the intrahepatic tract.

3. Bleeding: usually nosebleeds, bleeding under the skin.

4. Fatigue, weight loss, unclear fever and edema.

5. Jaundice, ascites, pruritus.

Guangzhou Modern Cancer Hospital experts, some typical symptoms of the development of liver disease only occur when you arrive late, and then surgery often has missed opportunities, so self-examination is usually very important.

When feeling tired, fatigue cannot be sustained remission, it is likely to be a sign of liver disease, chest feeling boring place, or right stomach blunted upper pain sensation, such as feeling of pressure and discomfort, weight loss, if there is an unclear fever and jaundice.

 
When the above symptoms, do not necessarily suffer from liver cancer, but still go to the hospital for liver cancer as early as possible the relevant examination to determine the condition, related treatment as soon as possible. Early liver cancer to get timely and effective treatment, can greatly extend life span, improve quality of life.

Reduce Meat Consumption to Maintain Blood Sugar Levels

Reduce Meat Consumption to Maintain Blood Sugar Levels
Reduce Meat Consumption to Maintain Blood Sugar Levels - Diabetics, are required to maintain their diet so that blood glucose levels do not continue to soar. In one study it was mentioned that reducing animal products can help improve glucose control, so that it can keep blood sugar levels more stable. Reducing meat consumption can also help you lose weight.


Maintain blood sugar levels by reducing meat

A recent study states that eating patterns that prioritize vegetable protein provide more benefits.

 
Over the past few years, people who have chosen to become vegetarians and vegans are increasing. This makes the researchers add evidence that supports the plant-based diet.

In this study, scientists want to find out whether reducing the intake of animal food sources can properly maintain blood sugar levels. As a result, there is scientific evidence that eating meat too often can increase the risk of developing type 2 diabetes.

Research has also shown that a diet or diet that is rich in vegetables, fruits, nuts, and seeds can reduce the risk of developing this disease.

For this reason, experts now consider that a plant-based diet is the best choice for preventing and controlling diabetes.


Increase vegetable protein to maintain blood sugar

In 2018, the American Association of Clinical Endocrinologists and the American College of Endocrinology release new guidelines. They write that diabetics must try to achieve and maintain optimal weight through a plant-based plan.

A fact shows that people who often consume vegetable protein have fewer complaints of nerve pain (neuropathy) associated with diabetes. Plus, fasting glucose levels drop more sharply, which is a sign of increased glucose control.

It was also noted that there was a decrease in HbA1c levels (the average glucose value for the last few weeks / months), in those who regularly ate foods from vegetable protein. This proves that reducing meat intake can help maintain blood sugar levels.
Benefits of reducing meat consumption

In addition to maintaining blood sugar levels, routine eating foods made from plants also shows good results in weight loss.

There are also a number of other benefits if you make vegetable protein your main source of protein, such as being able to reduce blood fat levels quickly.

Body weight and high levels of fat in the blood are known to be one of the triggers for cardiovascular disease. The disease itself is also known as one of the complications of people with diabetes.

When blood sugar levels are awake, body fat and weight drop, this will make you avoid the complications of diabetes because the process of maintaining blood sugar levels works well.

In the six studies analyzed by researchers, people who followed a plant-based or vegan diet could also stop drinking or reduce the medication they were taking for diabetes or blood pressure. This finding supports previous claims about the physical benefits of a plant-based diet.


Danger of meat consumption in diabetics

Reducing meat can be one way to keep blood sugar levels increasingly proven by the existence of a study.

The study comes from researchers in Finland who analyzed the eating patterns of more than 2,300 men, ages ranging from 42 to 60 years. At first, no participant had type 2 diabetes.

After 19 years, the researchers found that those who ate more animal protein and less vegetable protein had a 35 percent greater risk of developing diabetes. This includes all types of processed and non-processed red meat and white meat.

Not only the original form of meat, other parts of animals, such as innards or tongue, also contribute to diabetes. The study concluded that choosing vegetable protein and eggs can help prevent type 2 diabetes.

Recent research from Harvard University found that people who ate one serving of red meat every day had a 19 percent higher risk of developing type 2 diabetes than those who did not. A small portion of processed red meat, such as hot dogs or two pieces of meat, increases the risk of diabetes by 51 percent.

The study concludes that choosing whole grains, nuts, low-fat milk, fish and poultry rather than red meat is better at keeping blood sugar stable and reducing the risk of diabetes.


Why can meat increase blood sugar?

The exact reason why meat is not too recommended (especially for red meat and processed meat), is not certain. However, researchers believe there are three main components that increase the risk of diabetes, namely:
 
  • Sodium. This substance can increase blood pressure which can cause insulin resistance.
  • Nitrates in processed meat can increase insulin resistance and damage pancreatic function.
  • Iron found in red meat can cause cell damage and chronic inflammation.

If you have a history of diabetes or are at risk of being affected, avoiding meat can be one way to maintain blood sugar levels so that diabetes stays under control.

The slightest change can mean. Try to reduce it little by little. You can also replace some protein from meat to vegetable protein.

Can We Recover Completely from a Stroke?

Can We Recover Completely from a Stroke?
Can We Recover Completely from a Stroke? - Even though the treatment period has passed, stroke patients must undergo a recovery phase. This stage is quite time consuming, so to recover from a stroke can not be instant. Then, after undergoing a recovery period, can the patient recover from a stroke?
 

Can recovery from a stroke cure?

According to the National Stroke Association, 10% of people who suffer a stroke are almost completely cured. However, these people still have disorders that are not too severe as when they suffered a stroke.

While other sufferers still need special care to deal with the disorder. In essence, the possibility of complete recovery is indeed very small. This is because there are still many sufferers who have injuries that interfere with their daily functions.
 

Supporting factors for stroke recovery are successful

In addition to routinely attending the recovery session, it turns out there are still other supporting factors that make this treatment work.

1. Physical factors

Starting from how severe you have a stroke to what has been affected. This has an important role in stroke recovery, to find out more about what steps to take.

2. Psychological factors

This factor is very important in the recovery process. Do you have the desire of yourself to recover or the motivation is lacking. This greatly affects your participation in this process.

3. Social factors

Apart from yourself, it turns out that enthusiasm and motivation from family and friends are also important. If you have begun to feel tired of undergoing treatment, there will always be people around you who encourage and help with this stroke recovery process.

4. When to start treatment

If you start treatment for an earlier stroke, it is very influential in the recovery process. This is because when we realize earlier, doctors can analyze and most likely can cure it before the stroke spreads to vital parts.
 

Reduces the risk of stroke recurrence

After you suffer a stroke and try to cure it, the risk for a stroke after recovery is still lurking. However, you can minimize these opportunities, by :

1. A healthier diet

The food and drinks you consume are very influential in the development of your brain. Reduce foods that contain high levels of sugar, saturated fat and salt. This can affect blood pressure and cholesterol in the body. Both of them apparently can reduce the cognitive system of the brain and the ability to think in old age later.

2. Regulates the main factors for stroke

The main factors that interfere with the recovery of stroke are high blood pressure, smoking, and atrial fibrillation. Therefore, avoid things that can trigger all three of these factors so that the chance to recover from a stroke is even greater.

3. Take medication

In addition to a healthy lifestyle and avoiding the main factors of stroke, of course taking drugs regularly is a must to reduce the chances of another stroke.

Other article :
4 Things You Need to Notice If You Want to Return to Work After Stroke
  • Lower blood pressure
  • Control atrial fibrillation
  • Reducing the chance of clots.

In conclusion, stroke recovery takes a very long time and patience is high. If you encounter some difficulties during this process, this is very normal. Not despairing and continuing to believe that you can recover is the key to healing.

Several Methods for Treating Colon Cancer

Several Methods for Treating Colon Cancer
Several Methods for Treating Colon Cancer - Colon cancer sufferers have a great danger, until now people with colon cancer through methods such as surgery, chemotherapy, cell immunotherapy, etc. improve the life of treatment for colon cancer patients, reduce the impact of colon cancer in patients, make colon cancer patients recover better, help colon cancer patients early to get rid of disease disorders.

Traditional Colon Cancer Treatment Method

1. Operation Method

Treatment of colon cancer begins with cutting surgery, and focuses on a combination of preoperative chemotherapy, radiotherapy and other treatments to increase the percentage of cutting surgery, decrease the rate of recurrence after surgery and increase survival rates.
 
 
2. Chemotherapy

About half of colon cancer patients with metastasis and relapse after surgery, in addition to some patients with early stage, advanced patients and cutting surgery patients are asked to undergo chemotherapy. In combination chemotherapy colonic cancer treatment is the exception to an important therapeutic measure for advanced surgical treatment.

(1) Body Intravenous Chemotherapy Program

5-FU-based colon cancer chemotherapy program, with tetrahydrofolate as a regulatory dose to increase the effectiveness of the effect of a 5-FU dose.

(2) Oral Chemotherapy

Colonic cancer oral chemotherapy drugs mainly refer to fluoropyrimidine drugs, after being absorbed once or repeatedly through metabolism into 5-fluorouracil, functioning as an anti-cancer effect. Oral chemotherapy in clinical care has high treatment outcomes, mild side effects, ease of dosage, outpatient treatment, appropriate chemotherapy for elderly tumor patients and families becoming a new trend in the treatment of colon cancer.
 

New Technology for Treatment of Colon Cancer - Method of Natural Cell Therapy

With the development of medical technology, colon cancer patients have more choices, Natural Cell Therapy methods can greatly reduce the health damage of colon cancer patients. The method of cell immunotherapy is a remarkable achievement in the medical field, for the treatment of tumor diseases that have significant treatment results.

Guangzhou Modern Hospital cancer experts point out that the cell's natural therapy method is based on the immune system, has good differentiation and emphasizes immune cell function, through which immune cells can treat tumor disease, this is what is called the principle "using own cells to treat diseases ". Under normal circumstances, the development of large body tumor cells, suppresses the growth of immune cells, by cultivating immune cells that are maintained, then put back into the body effectively limiting tumor proliferation and metastasis. Due to cancer treatment throughout the body and no significant side effects on the human body, the advantages of treatment that do not have significant pain, and other benefits, the method of cell immunotherapy is currently the most effective and safe therapy.
 

Advantages of Natural Cell Therapy

The most important treatment method for natural therapy for colon cancer cells is to take the patient's immune cells (DC-CIK), then go through the process outside the body to breed and extract the patient's immune cells, then put them back into the patient's body, thereby regulating immune function the patient's body by increasing cancer fighting ability, the most important thing is that CIK cells can actually kill cancer cells in the body, ultimately achieving the goal of cancer treatment.
 

The advantages of the cell immunotherapy method are mainly reflected in two aspects

First the method of cell immunotherapy is the whole body, enhancing the patient's immune function, not just the local part. Second, the cell immunotherapy method kills tumor cells, can completely remove cancer cells so as to prevent recurrence and spread.

6 Ways to Diagnose Colon Cancer

6 Ways to Diagnose Colon Cancer 6 Ways to Diagnose Colon Cancer - The initial symptoms of colorectal cancer, patients are easily ignored, and doctors when they are often "dysentery", "enteritis" and other disease processes. Bowel obstruction can occur once or the abdominal mass is palpable, cancer generally has reached the middle and end. Therefore, the diagnosis of colorectal cancer is very important, the diagnosis can certainly improve the treatment of colorectal cancer.


How many ways to diagnose colon cancer? here are 6 ways to diagnose colon cancer

1. Stool blood test :
 

Proliferation of large intestinal cancer tissue is usually a small amount of blood flowing blood to the bench will be discarded. Occult fecal blood tests can detect a small number of components of blood in the stool, several blood tests or persistent occult shows positive, then request chronic gastrointestinal bleeding, must be aware of further examination and the presence of digestive tumors.

2. Digital rectal examination : 

The doctor uses the glove after the index finger and applies the lubricating anal area, the index finger is inserted into the rectum to examine the lump.

3. Endoscopy : 

Endoscopy is the most important cancer screening tool, where changes in bowel habits or blood in the stool and rectal examination have abnormal findings, must be sigmoidoscopy or colonoscopy.

(1) sigmoidoscopy: Straight type, 30cm longest, comfortable check, biopsy under direct vision, suitable for examining the following parts of sigmoid lesions.

(2) colonoscopy: 120-180cm long, can be bent, can observe the entire intestine, to make electric cut, coagulation and biopsy can detect initial lesions. It is difficult to diagnose a condition check when it can be used for this check. Therefore, if found to have symptoms of suspected colorectal cancer, you must go to the hospital for examination, early detection and early treatment.

4. X-ray examination : 

Including gastrointestinal examination of barium full food and barium enema. For colon cancer patients with barium enema it is appropriate. For smaller lesions can also be found in injecting intestinal gas for double barium contrast gas, check well. X-ray examinations of intestinal morphology can be observed, with or without some polyps and some focus.

5. B-scan, CT or MRI : 

This examination indirectly diagnoses bowel cancer, but the location of the tumor, its size, and the relationship with the surrounding tissue, lymph nodes and liver metastases have some value considerations that can help doctors to treat cancer patients colorectal to develop the best solution.


6. CEA (CEA) : 

Carcinoembryonic antigen (CEA) has generally been determined to carry out, colorectal cancer is the most important of the examinations. It is generally considered to evaluate the therapeutic effect and the valuable and continuous prognosis of determining serum CEA can be used to observe the effects of surgery or chemotherapy.

Symptoms of Brain Cancer that Generally Occur in Most People

Symptoms of Brain Cancer that Generally Occur in Most People
Symptoms of Brain Cancer that Generally Occur in Most People - Brain cancer, also called intracranial tumor, includes brain parenchyma in primary brain cancer that experiences metastasis from the brain to other parts of the body from secondary brain cancer

What are the causes of brain cancer?

1. A wave of radiation emitted by cellphones and computers that can increase the role of cancer cells.

2. Research has shown that the occurrence of brain cancer is directly related to the use of pesticide drugs, solvents, dyes and formaldehyde. And also for pregnant women, the use of alcohol or hair dye will increase the risk of children suffering from neuroblastoma.

3. Trauma and collisions are also shown to stimulate brain cancer, meningeal scar tissue can trigger the creation of tumors, traumatic tumors occur mainly on the basis of the dura and arachnoid injury. In addition, existing traumatic brain injury will accelerate the growth of brain tumors.

4. Radiation : radiation exposure is one of the causes of brain cancer.

 
What are the most common symptoms of cancer?

1. Headache : headache that is often felt at 4:00 a.m. to 5:00 a.m., often waking up due to pain, the more deeply the sleep feels pain. Generally the pain is reduced after waking up in the morning at 08.00 - 09.00.
 
2. Vomiting a lot : different from vomiting caused by digestive diseases. In brain cancer patients, vomiting often begins with a feeling of fullness or fatigue in the stomach, nausea, abdominal pain or diarrhea. And vomiting caused is not related to food eaten, more caused by prolonged headaches and severe vomiting. Vomiting like this is caused by the medulla oblongata nerve which experiences an increase in primary intracranial pressure.

In addition, people with brain cancer also commonly experience seizures, exophthalmos (one prominent eyeball), next to deafness, hemiplegia (side paralysis), unclear speech, difficulty opening the eyelids, diplopia (vision shaded) or difficulty swallowing food, vertigo, imperfect movements are the symptoms most often found in patients with brain cancer.
