Which kind-hearted person helps to look at this pathological examination report of renal cancer!
Renal cell carcinoma, also known as renal cell carcinoma, is high in 40-65 years old, with more males than females. Originated from renal tubular epithelial cells, it can occur in any part of renal parenchyma, but it is very common up and down, and a few invade the whole kidney; The incidence rate of left and right kidneys is similar, and bilateral lesions account for 1%-2%. Most patients with renal cell carcinoma die within one year after diagnosis without treatment, and some can survive for 2-5 years. There are many factors that affect the prognosis. Early cell differentiation is good, and the combination of traditional Chinese and western medicine can be treated in time, reasonably and for a long time, and the prognosis is good, otherwise it will be poor.
At present, the etiology of renal cell carcinoma is not clear. It is believed that chemical carcinogens excreted through the kidney can induce renal cell carcinoma. Hormone, radiation, virus infection, smoking, long-term use of phenacetin drugs, long-term exposure to lead-containing substances and some chronic kidney diseases may be related to the occurrence of renal cell carcinoma.
The clinical manifestations of renal cell carcinoma are varied, sometimes without any symptoms, but the tumor has progressed widely in the body, and even there are signs of metastasis such as lung and bone. Hematuria, low back pain and mass are often referred to as three typical symptoms of renal cell carcinoma in clinic. (1) Hematuria is the most common symptom, which often manifests as intermittent painless gross and/or microscopic hematuria. (2) Low back pain often manifests as persistent dull pain. When the tumor invades the nerve or lumbar spine, it will cause severe pain. Hematuria condenses into a cord-like blood clot in the ureter, which can cause waist pain when discharged with urine. (3) About 65,438+00% patients with renal cell carcinoma can touch the mass in the waist or upper abdomen. Tumors formed in the early stage of the kidney are difficult to be palpated, and can only be palpated if the diameter exceeds 3-5 cm. Masses are usually hard, uneven or nodular. When the emaciated patient or tumor is located in the lower pole of the kidney, the physical examination can detect the mass. If the mass is fixed, it means that there is infiltration around the kidney and the prognosis is not good. The simultaneous occurrence of the above three symptoms is rare, accounting for about 10%- 15%. If it appears at the same time, it is often a sign of late.
Because renal cell carcinoma is a kind of tumor with high malignant degree, many patients have obvious emaciation, anemia, low fever, loss of appetite and other malignant constitutions when they see a doctor. A few patients may be accompanied by varicocele on the left side. When the inferior vena cava is invaded, it may be accompanied by edema of lower limbs. If there is lung or bone metastasis, corresponding symptoms may appear. Through a large number of clinical observations, it is found that some patients with renal cancer may also be accompanied by symptoms of endocrine disorders. This is because kidney cancer can secrete a variety of endocrine hormones, causing a series of corresponding symptoms.
For those over 50 years old who have one of the three major symptoms and have fever of unknown cause, they should be highly vigilant, conduct relevant examinations in time, and diagnose or eliminate them as soon as possible. Examination items: (1) routine urine examination. (2) Urinary tract plain film. (3) Renal artery and pyelography. (4) b-ultrasound examination. (5)CT examination. (6) nuclear magnetic resonance examination. (7) Radionuclide inspection, etc.
