Late symptoms of nephroblastoma?

summary

Advanced Wilms tumor is a very common malignant tumor, early clinical symptoms are not very obvious, so it is often ignored by patients. Most patients will find that they have severe nephroblastoma once they have nephroblastoma in the middle and advanced stage, so when nephroblastoma enters the advanced stage, they need to seize the time for treatment, so as not to miss the best opportunity for treatment. Late symptoms of nephroblastoma? Let's talk about it.

Late symptoms of nephroblastoma?

1. 80% ～ 90% of the patients with abdominal mass were diagnosed as abdominal mass. Most of them were found by accident, but they were asymptomatic. Generally, the abdominal mass was found when the mother bathed or dressed the child, or the medical staff did the general examination for other reasons. The mass is located in one side of the abdomen, which is oval in shape. The surface is smooth and smooth, and the texture is solid without tenderness. The inner and lower boundaries of the mass are clear. The upper boundary is covered by the costal margin and cannot be touched. Palpation of the abdomen and waist with both hands can feel that the waist is filled by the tumor. The tumor was relatively fixed and could not move. The size of the mass varies, and the larger one may account for 1 / 3 to 1 / 2 of the whole abdomen. In the later stage, the mass often exceeds the abdominal midline and pushes the abdominal viscera to the opposite side. It should be pointed out that repeated palpation and squeezing of the tumor can promote the tumor cells to enter the blood stream and cause distant metastasis, so special attention should be paid to it.

2. Pain and digestive system symptoms it has been reported that the first symptom of 25% nephroblastoma is lumbocrural pain. In fact, because most of the pain is not serious and children are not good at narration, most of them are not noticed. Children with falls, falls or abdominal trauma may have symptoms of acute abdomen. Occasionally, children may have sudden paroxysmal pain, which is caused by sudden bleeding in the tumor, excessive expansion of renal capsule or temporary obstruction of ureter by blood clot. Children often have obscure gastrointestinal symptoms, such as nausea, vomiting and loss of appetite.

3. Hematuria hematuria occurs in 20% of the cases, and hematuria is the first symptom in about 10% of the cases. Generally painless and intermittent hematuria, a small amount, sometimes accompanied by blood clots. When pediatricians see this symptom, even if the abdomen does not touch the mass, they should also do B-ultrasound, intravenous pyelography or CT examination, which may find small tumors in the central part of the kidney. However, in most cases, hematuria is a more advanced symptom, the tumor has been quite large, infiltrating the calyces, into the pelvis. Microscopic examination of urine showed that about 1 / 3 cases contained multiple red blood cells.

matters needing attention

The diet should be light, pay attention to hygiene, and match the diet reasonably. The cure rate of total nephrectomy is about 47%. Postoperative radiotherapy can increase the survival rate by 60%. It increases or decreases with the age of the child and the stage of the tumor.
