Surgery To Ease Your Symptoms
If your stomach cancer has spread beyond your stomach, it may not be possible to remove it using surgery.
However, if your stomach has been significantly affected by cancer it can cause a blockage, which prevents food from being properly digested. A blocked stomach can cause symptoms such as stomach pain, vomiting and feeling very full after eating.
If your stomach is blocked, there are a few options:
- stenting a stent is a plastic or wire mesh tube inserted through the oesophagus using an endoscope under local anaesthetic after being inserted, the stent will be expanded and open up the stomach
- partial or total gastrectomy to remove the blockage and improve your symptoms

What Are The Different Stages Of Stomach Cancer
Stomach cancer is staged based on the severity of cancerous cell growth and spread. Adenocarcinoma is initially evaluated by the tumor, node metastasis system.
- T: How deeply has the tumor spread into the stomach wall?
- N: Has the stomach cancer spread to the lymph nodes?
- M: Has the stomach cancer spread to other parts of the body?
After the TNM staging information has been taken into account, the cancer is staged at 0 or 1 to 4. Tumor classifications for staging are as follows:
- Stage 0 is early cancer on the surface of the stomach lining.
- Stage 1A or 1B
- Stage 2A or 2B, commonly with deeper stomach wall involved
- Stage 3A or 3B or 3C, commonly with lymph node involvement
- Stage 4 means cancer has metastasized elsewhere in the body outside of the stomach.
What Are The Physical Symptoms Of Gastric Cancer Her2 Positive
The symptoms of cancer are not affected by the HER2 status. In gastric cancer, the symptoms patients experience can depend on where in the stomach the cancer is, but typically include:
- Difficulty swallowing
- Nausea or vomiting
- Unexplained weight loss
The above symptoms can be caused by other health issues, so make sure to talk to your doctor if you are experiencing any of these.

What Is Stage 4 Stomach Cancer
Stomach cancer is cancer that starts in the stomach. Its staged according to how far it has spread at the time of diagnosis.
In stage 4, stomach cancer has spread through tissue, the bloodstream, or lymph system to distant parts of the body. Cancer may be found in organs such as the liver, lungs, or distant lymph nodes.
Stage 4 is also called advanced stomach cancer.
Knowing the stage of stomach cancer helps determine treatment options. It also provides a general overview of what to expect.
Keep reading to learn more about stage 4 stomach cancer, how its treated, and the five-year survival rate.
usually not curable, but its certainly treatable.
The goal of treatment is to ease symptoms and control the cancers growth. Your doctor will recommend therapies based on your age and overall health, including any other health conditions you may have. Your options also depend on specific characteristics of the cancer.
Treatment for cancer usually involves a combination of therapies. Your treatment plan can be adjusted based on how well its working. Tell your doctor if you have new symptoms along the way so they can be factored in.
Some treatments for stage 4 stomach cancer are:
Prognosis Depends On Stage At Diagnosis
Long-term prognosis for pancreatic cancer depends on the size and type of the tumor, lymph node involvement and degree of metastasis at the time of diagnosis. The earlier pancreatic cancer is diagnosed and treated, the better the prognosis.
Unfortunately, pancreatic cancer usually shows little or no symptoms until it has advanced and spread. Therefore, most cases are diagnosed at later, more difficult-to-treat stages.

Stages Of Stomach Cancer
About 90 to 95 percent of all stomach cancers are adenocarcinomas that start in the mucosa, the innermost stomach lining.
Intestinal adenocarcinomas have a better prognosis and may respond to targeted therapy. Diffuse adenocarcinomas spread more quickly and are difficult to treat but are less common.
Most stomach cancers start in the innermost layer of the stomach wall called the mucosa. Doctors use the TNM system to stage stomach cancer.
T stands for tumor, N stands for node and M stands for metastasis. Doctors evaluate how deeply the main tumor has spread , if the tumor has reached lymph nodes and if the cancer has spread to other parts of the body . They then stage each tumor from Stage 0 to Stage IV based on the TNM system.
Stage IIA cancers have three possible conditions.
They may have:
- Spread into the submucosa and three to six lymph nodes, or
- Spread into the stomach muscle layer and one or two lymph nodes, or
- Spread into the subserosa with no lymph node involvement.
They may have:
- Spread into the submucosa and seven to 15 nearby lymph nodes, or
- Spread to the muscle layer and three to six nearby lymph nodes, or
- Spread to the subserosa and to one or two nearby lymph nodes, or
- Spread to the serosa and spread to one to six nearby lymph nodes.
What Is A 5
A relative survival rate compares people with the same type and stage of cancer to people in the overall population. For example, if the 5-year relative survival rate for a specific stage of stomach cancer is 70%, it means that people who have that cancer are, on average, about 70% as likely as people who dont have that cancer to live for at least 5 years after being diagnosed.

Understanding The Difference Between Cure And Remission
Cure means that there are no traces of your cancer after treatment and the cancer will never come back.
Remission means that the signs and symptoms of your cancer are reduced. Remission can be partial or complete. In a complete remission, all signs and symptoms of cancer have disappeared.
If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment. These cells may cause the cancer to come back one day. For cancers that return, most do so within the first 5 years after treatment. But, there is a chance that cancer will come back later. For this reason, doctors cannot say for sure that you are cured. The most they can say is that there are no signs of cancer at this time.
Because of the chance that cancer can come back, your doctor will monitor you for many years and do tests to look for signs of cancers return. They will also look for signs of late side effects from the cancer treatments you received.
How Can You Detect Stomach Cancer Early
Be sure to contact your medical provider if you feel like something is not right. There are screening tests for stomach cancer when people are at risk for or are experiencing signs and symptoms. Diagnostic evaluations for gastric cancer include:
- Complete medical history and physical exam
- Upper gastrointestinal endoscopy to view the esophagus, stomach and small intestine after sedation. A small, flexible tube is inserted into the mouth with a tiny camera on the end that allows the doctor to see inside your stomach.
- Biopsy of stomach tissue to be evaluated under a microscope
- CT scan to visualize organs during X-ray
- Endoscopic ultrasound to diagnose and treat stomach cancer at the same time by visualizing organs and nearby blood vessels
- Positron emission tomography scan to illuminate cancer cells. A radioactive sugar tracer is used because cancer cells use more sugar than healthy cells and the tracer illuminates the cancer cells.

After A Diagnosis Of Stomach Cancer
After being diagnosed with a stomach cancer, you may feel shocked, upset, anxious or confused. These are normal responses. A diagnosis of a stomach or oesophageal cancer affects each person differently. For most it will be a difficult time, however some people manage to continue with their normal daily activities.
You may find it helpful to talk about your treatment options with your doctors, family and friends. Ask questions and seek as much information as you feel you need. It is up to you as to how involved you want to be in making decisions about your treatment.

How Is Stomach Cancer Treated
There are several approaches to treating stomach cancer. In many cases, surgery can be avoided.
In the early stages when the cancer is limited to the superficial layers of the stomach, the cancer can be removed through an upper endoscopy performed by a gastroenterologist. In this procedure , the tumor is dissected from the rest of the gastric wall and removed through the mouth.
Once the tumor invades beyond the superficial layers of the stomach, surgery will be required to remove the stomach and connect the esophagus to the small intestines to allow for digestion.
Radiation therapy uses high-powered beams of energy to kill cancer cells. Chemotherapy uses chemicals to kill the cancer cells. These treatments are generally combined.
There are also several drugs to treat stomach cancer. Treatment depends on how severe the cancer is and is decided upon by a doctor after diagnosis.

What Is Stomach Cancer
Stomach cancer starts in the mucosa, the innermost layer of the stomach walls five layers of tissue. As it grows, it spreads to the other four layers: submucosa, muscle, subserosa and serosa.
The good news about stomach cancer is rates are on the decline in the United States. This cancer accounts for only about 1.5 percent of all cancers diagnosed each year, according to the American Cancer Society.
Treatment for stomach cancer depends on how far the cancer has spread. The right regimen may improve quality of life and extend survival time.
Quick Facts About Stomach Cancer
- In 2021, there will be about 26,560 new cases of stomach cancer and 11,180 deaths.
- About 60 percent of people diagnosed with stomach cancer are 65 or older.
- More men than women get stomach cancer.
- The overall five-year survival rate is 32 percent.
- Early stage stomach cancer symptoms include nausea, loss of appetite, indigestion, feeling bloated after eating and heartburn.
- Smoking, stomach infections, older age, male gender, eating processed or smoked meats and family history of cancer are risk factors for stomach cancer.
- Treatments for stomach cancer include surgery, radiation therapy, chemotherapy, targeted therapy and immunotherapy.
Standard Treatment Options For Stages Ii And Iii Gastric Cancer
Standard treatment options for stage II gastric cancer and stage III gastric cancer include the following:
Regional lymphadenectomy is recommended with all of the above procedures. Splenectomy is not routinely performed.
No randomized trials of adjuvant chemoradiation versus perioperative chemotherapy have been undertaken.
Surgical resection
Because of the high risk of locoregional and distant recurrence, perioperative and postoperative therapy should be considered in addition to surgery.
Surgical resection with regional lymphadenectomy is the treatment of choice forpatients with stages II and III gastric cancer all eligible patients undergo surgery. If the lesion is not in thecardioesophageal junction and does not diffusely involve the stomach, subtotalgastrectomy is the procedure of choice. When the lesion involves the cardia,proximal subtotal gastrectomy or total gastrectomy may be performed withcurative intent. If the lesion diffusely involves the stomach, totalgastrectomy and appropriate lymph node resection may be required. The role ofextended lymph node dissection is uncertain and in some series isassociated with increased morbidity. As many as15% of selected stage III patients can be cured by surgery alone, particularlyif lymph node involvement is minimal .

Can You Treat Stomach Cancer By Changing Your Diet
Using a healthy diet to treat stomach cancer is not enough to cure cancer, but you can talk to your doctor about using it as part of a medical plan to improve your overall health. Those who eat a diet rich in produce like fresh fruits and vegetables and whole grains may decrease their risk for stomach cancer. However, some studies show that increasing plant-based foods reduces the risk of fatal stomach cancer in men, but not women. Talk with your healthcare provider about your dietary options.

Does Stomach Cancer Affect Men And Women Differently
It is important to look for signs of stomach cancer in adults over the age of 55. However, it most commonly affects those in their 60s or 70s. While it is crucial to be aware of the signs of stomach cancer in females, men are more likely to develop stomach cancer. In 2020, 16,980 men and 10,620 women are projected to be diagnosed with the disease. Men have a lifetime risk of 1 in 95 of developing stomach cancer, while women have a 1 in 154 risk. The signs of stomach cancer in men are typically no different than in women.
Stage 0 Gastric Cancer
Surgery
Stage 0 is gastric cancer confined to mucosa. Experience in Japan, where stage0 is diagnosed frequently, indicates that more than 90% of patients treatedby gastrectomy with lymphadenectomy will survive beyond 5 years. An Americanseries has confirmed these results.
Endoscopic mucosal resection
EMR has been studied in Japan and throughout Asia in patients with early-stage tumors with good-risk features that have a lower risk of nodal metastasis. Intramucosal tumors have a lower risk of nodal metastasis than submucosal tumors. Careful patient selection by the above criteria, treatment with an experienced endoscopist, and close surveillance should be considered.
