Lung apex tumor syndrome is still very common in cancer. It is mainly a syndrome of pain caused by the tumor at the apex of the lungs after pressing on the upper extremities. There are many causes, and the most common is lung cancer. Many people do not know what is pancoast (pulmonary tumor syndrome) cancer. Here is a brief introduction.

　　Pancoast syndrome, also known as lung tip tumor syndrome, refers to a group of symptoms of intractable upper extremity pain and ipsilateral Horner syndrome caused by tumor invasion and compression of the lung tip.

　　 Common causes include lung cancer, pleural mesothelioma, breast cancer, thyroid cancer, and esophageal cancer. Lung cancer is the most common, especially lung apex cancer or superior lung sulcus cancer, and sometimes metastatic carcinoma of the lung apex.

　　Chest X-ray examination, no abnormalities or only blurred shadows at the apex of the lungs in the early stage. When the mass gradually increases, massive shadows in the lungs may appear, and 1 to 3 ribs are often invaded and eroded , Nearby vertebrae can also be damaged.

　　Therapeutic method: 1. Analgesic treatment, can use morphine, pethidine (dulending) and other analgesics or take nerve block therapy. At the same time, nutrition and supportive therapy should be strengthened. 2. For the treatment of primary tumors, radiotherapy or chemical drugs should be given as appropriate according to the primary tumor. Most patients have lost the opportunity for surgery, but for those with severe pain, although they can not remove the lesion, they can do nerve tumor dissection or thoracic nerve excision Ⅰ and Ⅱ to reduce pain symptoms. 3. Surgical treatment.

　　Intrinsic traits are mainly caused by lung cancer or other tumors. When there are clinical signs of severe shoulder and arm pain, hand muscle atrophy and ipsilateral Horner syndrome, you should go to the hospital for an early examination to further find the cause. If it is caused by a tumor, there is generally no chance of radical surgery and active treatment of the original disease While strengthening supportive therapies.
