When clinical symptoms such as nausea, vomiting, gastric distension or upper abdominal pain, acid reflux, or hematemesis, as well as melena occur, it is necessary to consider the possibility of gastric cancer and seek timely medical attention. Completing a gastroscopy and obtaining a biopsy under gastroscopy are essential. If cancer cells are found, this is the most important diagnostic method for confirming gastric cancer. After the diagnosis of gastric cancer, further examinations like endoscopic ultrasound and CT scans of the chest and abdomen are required to assess the approximate stage of the patient and to decide the subsequent treatment plan.

How is stomach cancer treated?

The treatment for gastric cancer now includes surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy, among others. The specific treatment plan is formulated based on various factors such as the staging of the cancer, the patient's overall condition, and the presence of any underlying diseases, which are all taken into consideration before deciding on a treatment plan. For patients in the early stages who are generally in good condition, surgical resection can be evaluated and is primarily curative. Post-operative treatment decisions, such as whether to pursue adjuvant radiotherapy or chemotherapy, depend on the pathology results and the presence of high-risk factors for recurrence. For patients in advanced stages who are found to have distant metastases upon diagnosis, treatment is primarily chemotherapy. Additionally, there are broad-spectrum targeted therapies against angiogenesis, such as apatinib, which are suitable for patients with advanced gastric cancer or those who do not respond well to chemotherapy, serving as a secondary or tertiary line of treatment. These are some of the treatment methods for gastric cancer. It is crucial that the use of any medication is conducted under the guidance of a doctor.

What are the symptoms of gastric cancer?

Symptoms of stomach cancer patients are like those of early-stage stomach cancer patients, who generally present with some nonspecific gastrointestinal symptoms, such as nausea, vomiting, loss of appetite, and discomfort or acid reflux in the upper abdomen, similar to gastrointestinal ulcers or gastritis. These are some of the clinical manifestations of gastrointestinal symptoms. As the tumor progresses and invades the abdominal cavity or surrounding organs, the patient's symptoms will worsen, possibly causing overall abdominal bloating, discomfort, and even severe pain. Other symptoms include ascites, which is fluid accumulation in the abdominal cavity, vomiting, weight loss, anemia, and clinical manifestations such as vomiting blood or black stools, which are symptoms of gastrointestinal bleeding.

Is black stool a sign of stomach cancer?

Black stools might suggest stomach cancer, but most cases are not. Often, factors such as diet structure and medications can lead to transient black stools, which are physiological. For instance, consuming animal blood, foods containing pigments, and certain medications like blood tonics and bismuth drugs protecting the stomach lining can cause transient black stools. Once dietary adjustments are made or related medications are stopped, the stool color usually returns to normal. In pathological conditions, such as acute gastric mucosal lesions and bleeding from gastric or duodenal ulcers, black stools can also occur. Thus, the occurrence of black stools might suggest the possibility of stomach cancer, but in most cases, it likely is not.

Is chemotherapy for gastric cancer torturous?

The first common side effect of chemotherapy drugs is gastrointestinal reactions, such as nausea, vomiting, decreased appetite, diarrhea, constipation, or bloating, and other such gastrointestinal symptoms. The second is bone marrow suppression, such as decreases in white blood cells and platelets; a decrease in white blood cells can easily lead to infections, and low platelets can lead to a tendency to bleed. There are also liver and kidney damage, numbness of hands and feet in the peripheral nervous system, and clinical symptoms such as fingernail darkening, pigmentation, or hand-foot syndrome caused by fluorouracil. The severity of chemotherapy side effects varies greatly among patients and is related to each patient's general condition, exhibiting significant individual differences. Some patients may experience severe reactions to chemotherapy, while others may have milder reactions. However, during chemotherapy, we provide corresponding symptomatic treatments such as gastric protection, antiemetics, and cardioprotection, among others, to try to minimize the side effects caused by chemotherapy.

Can stomach cancer be cured? Can stomach cancer be cured?

Early-stage gastric cancer patients can undergo curative surgery, and then decide whether postoperative adjuvant radiochemotherapy is needed based on the specific pathological type and the presence of high-risk recurrence factors. Through these treatments, a cure can be achieved. Generally, if there is no recurrence or metastasis within five years, it is considered cured. For example, patients in stage IA, even without adjuvant chemotherapy, have a relatively high five-year survival rate, generally above 90% after curative surgery. However, if it is found to be advanced-stage, such as initial detection showing distant metastases to the liver, lungs, etc., these patients are primarily treated with systemic chemotherapy or symptomatic palliative care. In such cases, a cure is not achievable. Therefore, whether a cure is possible depends on the stage of gastric cancer and factors such as the patient's basic physical condition.
