What is Abdominal Cancer?

Abdominal tumors include abdominal wall tumors, stomach cancers, colorectal cancers, small intestine tumors, liver cancers, biliary tumors, pancreatic tumors, spleen tumors, peritoneal and retroperitoneal tumors, and tumors of the gastrointestinal and pancreatic neuroendocrine system.

Benign tumors of the abdominal wall include hard fibroids, fibroids, neurofibromas, hemangiomas, papilloma, and dermoid cysts. Malignant tumors include fibrosarcoma, cutaneous fibrosarcoma, melanoma, skin cancer, and metastatic cancer. The main one is described later.

Clinically, it is a painless oval-shaped mass in the abdominal wall, with a hard texture and slow growth. In most patients, tumors are found up to a few centimeters in diameter. When the abdominal muscles contract, the tumor outline can still be clearly identified, which can be distinguished from tumors in the abdominal cavity. In a few patients who were delayed in the consultation, the tumor showed invasive growth around the flank, and a large area of the abdominal wall was stiff, with a diameter of up to 10 centimeters.

Most tumors originate from rectus abdominis, external oblique muscles, internal oblique muscles, or transverse muscles of the sheath or aponeurosis of the abdomen, showing invasive growth into the muscle. The tumor is non-enveloped, with irregular edges and crab-foot-like shapes; the texture is as tough as rubber; Under a microscope, the tumor is composed of abundant collagen fibers and fewer fibrous cells, which are arranged in parallel; the cells have no atypia and mitotic phase; at the edge of the tumor, islets of striated muscle tissue surrounded by the tumor are often seen. The tumor morphology is benign, but it is easy to relapse. The disease is more common in young adults. Tumors usually occur in the dermis and are bulging. Under the microscope, the tumor was composed of spindle cells. The cells were different in length, fat, and thin, and they were mostly striated or swirled. Some cells could have significant atypia and rare mitotic phases, which is a low-grade malignant tumor. .

Treatment should be surgically removed. The scope includes the tumor and normal muscles, myomes, and aponeurosis. If the peritoneum is involved, it should also be partially removed. Incomplete resection is prone to relapse. If the abdominal wall defect is large after the tumor is removed, it can be repaired by turning over the anterior sheath of the rectus abdominis muscle and the wide fascia of the thigh, or repairing with silk spinning or polyester patch to prevent the formation of an incisional hernia. When the tumor has a wide range and cannot be removed, radiation therapy can be tried.

Gastric cancer is a malignant condition in which gastric mucosa epithelium becomes cancerous and is one of the most common malignant tumors. The main symptoms are gastric discomfort, abdominal distension, abdominal pain, loss of appetite, nausea and vomiting, weight loss, abdominal mass, melena, and abdominal mass. Gastric cancer occurs in the pyloric region of the stomach, followed by the small curvature of the stomach and the cardia. China has a high incidence of gastric cancer. The ratio of male to female incidence was 2.3 to 3.6: 1. It can occur at any age, but most often after middle age. Most are 50 to 60 years old, rare before 30 years old. Gastric cancer belongs to the categories of "stomach pain", "nausea", and "scar" in Chinese medicine.

Pancreatic cancer is the most common pancreatic cancer, and the incidence of pancreatic cancer has increased significantly in recent years. Pancreatic cancer has no typical clinical manifestations in the early stage, and there are many diseases that need to be identified in upper abdominal pain. Therefore, misdiagnosis and mistreatment are prone to occur. The misdiagnosis rate is 35.5% to 87.5%. It is often misdiagnosed as cholecystitis, gastrointestinal diseases, hepatitis, and pancreatitis.

The clinical manifestations of pancreatic cancer are hidden, and it is not easy to detect early. 80% of patients were diagnosed in the middle and advanced stages, and the surgical resection rate was low, about 5% to 15%.

Pancreatic cancer can be divided into pancreatic head cancer, pancreatic body cancer, and pancreatic tail cancer according to anatomical parts. Among them, pancreatic head cancer is the most common.

CA19-9 is the most promising diagnostic marker for early pancreatic cancer, with a diagnosis rate of 90%.

Pancreatic cancer is a radiation-insensitive tumor. Local radiotherapy can relieve pain in 30% to 50% of patients and inhibit tumor development to a certain extent.

CEA is elevated in 70% of pancreatic cancer patients. CEA can be used for dynamic follow-up before and after pancreatic cancer surgery. Regular determination of CEA is of reference value in predicting cancer recurrence.

Abdominal back pain, weight loss, and jaundice are the three major symptoms of pancreatic cancer. Pancreatic cancer can oppress and invade the abdominal plexus and cause severe and persistent abdominal pain.

Chemotherapy has no obvious effect on pancreatic cancer. In addition, the surgical resection rate is low. Effective specific anti-cancer therapy is the main treatment method for pancreatic cancer. Systematic and effective active plant anti-cancer drugs can make some patients with pancreatic cancer achieve long-term survival .

Apparent back pain in pancreatic cancer is mostly cancerous pain, and effective anti-cancer treatment is a prerequisite for pain relief. "Anti-cancer analgesic method" has ideal analgesic effect on abdominal and back pain of pancreatic cancer.
