Ovarian cancer originates when abnormal cells in the ovaries or fallopian tubes begin to grow and multiply uncontrollably. Metastasis describes the process where cancer cells detach from their original site and spread to other parts of the body, forming new tumors.
Pathways of Spread
Ovarian cancer commonly spreads through peritoneal dissemination, also called transcoelomic spread. This occurs when cancer cells shed from the primary tumor and travel within the peritoneal fluid, which fills the abdominal cavity. These cells can then implant on the surfaces of other abdominal organs, such as the stomach, omentum, and intestines.
While transcoelomic spread is the most frequent route, ovarian cancer cells can also spread through the lymphatic system or the bloodstream. Lymphatic spread involves cancer cells traveling through lymph nodes. Hematogenous spread happens when cancer cells enter blood vessels and circulate to distant locations.
Identifying Symptoms
When ovarian cancer spreads to the stomach, patients may experience nausea and vomiting. Early satiety, a feeling of fullness quickly after eating, is a common symptom. This can lead to a loss of appetite and unexplained weight loss.
Abdominal pain or discomfort is often described as a dull ache, pressure, or general tenderness. This pain can spread to the lower back. Bloating and an increase in abdominal size are common, sometimes due to fluid buildup known as ascites. These symptoms arise from the tumor pressing on the stomach or interfering with normal digestive function.
Diagnostic Procedures
Diagnosing ovarian cancer metastasis to the stomach involves a combination of imaging and tissue analysis. Computed Tomography (CT) scans are frequently used to visualize the extent of cancer spread within the abdomen and pelvis. Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scans can provide more detailed images and help identify areas of increased metabolic activity, suggesting cancer presence. These imaging techniques help determine the location and size of metastatic tumors.
Biopsies are essential for confirming the presence of cancer cells and determining their origin. This can involve a laparoscopic biopsy, where a small incision is made to collect tissue samples, or an image-guided biopsy, where imaging is used to direct the needle to the suspicious area. Pathological analysis of these tissue samples confirms the diagnosis. Tumor markers, such as CA-125, may be elevated in ovarian cancer, but they are not definitive on their own for diagnosing metastasis and are typically used in conjunction with other tests.
Treatment Strategies
Treating ovarian cancer that has spread to the stomach often involves a multi-pronged approach tailored to the individual. Systemic treatments like chemotherapy are commonly used, administered intravenously to circulate throughout the body and target cancer cells. Intraperitoneal (IP) chemotherapy, where drugs are delivered directly into the abdominal cavity, may also be considered. This method allows for higher concentrations of chemotherapy drugs to reach cancer cells within the peritoneal area, potentially improving effectiveness.
Targeted therapies are another option, focusing on specific molecules involved in cancer growth and spread. These drugs can interfere with pathways that cancer cells use to grow and divide. Surgical intervention, specifically cytoreductive surgery or “debulking,” aims to remove as much of the visible tumor as possible from the abdominal cavity. In some cases, this surgery may be combined with Hyperthermic Intraperitoneal Chemotherapy (HIPEC), which involves circulating heated chemotherapy solution directly within the abdomen immediately after tumor removal. A multidisciplinary team of specialists collaborates to determine the most suitable treatment plan.
Navigating Care and Support
Living with metastatic ovarian cancer affecting the stomach requires comprehensive supportive care to manage symptoms and maintain quality of life. This includes managing physical discomforts such as pain, nausea, and nutritional challenges. Dietitians can provide guidance on managing dietary needs and maintaining adequate nutrition despite digestive issues. Palliative care, which focuses on relieving symptoms and improving comfort, is integrated early in the treatment process.
A multidisciplinary healthcare team plays a significant role in providing holistic care. This team typically includes oncologists, surgeons, pain management specialists, and palliative care providers. They work together to address the patient’s physical, emotional, and practical needs. Emotional and psychological support for both patients and their families is also an important aspect of care, helping individuals cope with the challenges of the disease.
