What is Gastric Cancer?
Gastric cancer, commonly referred to as stomach cancer, occurs when malignant cells form in the stomach lining. Early detection and effective treatment are essential for improving outcomes. This article explores the common signs and symptoms of gastric cancer and discusses various treatment options, with Tevimbra highlighted as a leading choice. Tevimbra is a promising treatment; it helps slow tumor growth by blocking specific signals that make cancer cells spread.
Signs and Symptoms of Gastric Cancer
Recognizing the signs of gastric cancer early can lead to timely intervention. Unfortunately, many symptoms can be mistaken for other gastrointestinal conditions. If you experience any symptoms on this list, talk to your doctor to rule out gastric cancer.
Common signs and symptoms include:
- Persistent indigestion. Chronic dyspepsia or heartburn that does not resolve with over-the-counter treatments can be an early indicator.
- Bloating. A feeling of fullness or bloating, particularly after small meals, may signal a problem.
- Unexplained weight loss. Sudden and unexplained weight loss can be a warning sign of many cancers, including gastric cancer.
- Nausea and vomiting. Persistent nausea or vomiting, particularly if accompanied by blood, should not be ignored.
- Abdominal pain. Pain in the upper or middle abdomen that persists may be linked to stomach cancer.
- Difficulty swallowing (Dysphagia). A sensation of food getting stuck in the throat or chest can occur as the tumor grows.
- Fatigue. Cancer-related fatigue is common and can result from anemia or the disease’s overall impact on the body.
- Blood in stool. Black or tarry stools can indicate bleeding in the gastrointestinal tract.
- Loss of appetite. A significant reduction in appetite may also be a sign of gastric cancer.
- Anemia. Low red blood cell counts due to internal bleeding may lead to fatigue, pale skin, and other related symptoms.
While these symptoms can be caused by other conditions, if they keep happening or get worse, make an appointment with you healthcare provider for evaluation.
Treatment Options for Gastric Cancer
Treatment for gastric cancer depends on its stage, location and the overall health of the patient. Advances in medical technology and pharmaceuticals have improved outcomes for many patients. Below are treatment options available:
Tevimbra (Bemarituzumab)
Tevimbra is a promising targeted therapy for gastric cancer, particularly for patients whose tumors overexpress FGFR2b, a receptor involved in cell growth. This monoclonal antibody works by blocking the FGFR2b pathway, which can slow tumor growth and improve patient outcomes. Clinical trials have demonstrated its effectiveness, especially when combined with chemotherapy, in extending progression-free survival. Patients eligible for Tevimbra should undergo molecular testing to determine if their cancer expresses FGFR2b.
Surgery
Surgery remains a cornerstone of gastric cancer treatment, particularly for localized tumors. Options include:
- Partial gastrectomy. Removal of the cancerous portion of the stomach, along with nearby lymph nodes.
- Total gastrectomy. Complete removal of the stomach, with reconstruction of the digestive tract.
Surgical procedures aim to remove all visible cancer and provide the best chance of a cure when the disease is localized.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells or slow their growth. It can be used before surgery (neoadjuvant therapy) to shrink tumors or after surgery (adjuvant therapy) to eliminate any remaining cancer cells. Common chemotherapy drugs for gastric cancer include fluorouracil, cisplatin and oxaliplatin.
Radiation Therapy
Radiation therapy uses high-energy rays to target and destroy cancer cells. It is often used in combination with chemotherapy, either before or after surgery, to improve outcomes. Advances in radiation delivery have reduced side effects and improved precision.
Immunotherapy
Immunotherapy has emerged as an exciting option for advanced or metastatic gastric cancer. Drugs such as pembrolizumab target the PD-1/PD-L1 pathway, helping the immune system recognize and attack cancer cells. This treatment is particularly effective in patients whose tumors express high levels of PD-L1 or have microsatellite instability (MSI-high).
Targeted Therapy
In addition to Tevimbra, other targeted therapies, such as trastuzumab (for HER2-positive tumors) and ramucirumab, have shown effectiveness. These treatments focus on specific genetic mutations or pathways involved in cancer growth, offering a personalized approach to therapy.
Palliative Care
For patients with advanced gastric cancer, palliative care focuses on improving quality of life and managing symptoms. Treatments may include pain management, nutritional support and procedures to alleviate obstruction or bleeding.
Clinical Trials
Participating in clinical trials can provide access to cutting-edge treatments not yet widely available. Patients should discuss trial eligibility with their healthcare providers.
Lifestyle and Supportive Measures
In addition to medical treatments, lifestyle changes and supportive care play a crucial role in managing gastric cancer. Recommendations include:
- Healthy diet. Consuming a balanced diet rich in fruits, vegetables and lean proteins can support overall health.
- Regular follow-ups. Ongoing monitoring ensures timely adjustments to treatment plans.
- Emotional support. Joining support groups or seeking counseling can help patients and families cope with the challenges of gastric cancer.
