Kidney cancer
What are the characteristic symptoms of kidney cancer?
Most kidney cancer patients are discovered during health check-ups, and these patients may account for over 50%-60% of all kidney cancer cases. Among those with symptoms, the most common symptoms are lower back pain and blood in urine. A few patients also present with abdominal masses. 10%-40% of patients can exhibit paraneoplastic syndromes, manifested as high blood pressure, anemia, weight loss, cachexia, fever, abnormal liver function, hyperglycemia, increased erythrocyte sedimentation rate, and other changes. Additionally, symptoms such as bone pain, fractures, cough, and coughing blood can occur due to tumor metastasis.
Is stage II kidney cancer considered early stage?
The staging of kidney cancer is primarily based on the size of the tumor, whether there is lymph node metastasis, involvement of adjacent organs or lymphatic vessels, and metastasis to distant organs. The TNM staging system is commonly used in clinical settings to stage kidney cancer, where "T" represents the depth of tumor invasion, "N" represents the status of lymph node metastasis, and "M" represents distant metastasis. Stage II refers to a tumor with a maximum diameter greater than seven centimeters but confined to the kidney. Stage II is further divided into stage IIA and stage IIB. Stage IIA refers to a tumor with a maximum diameter greater than seven centimeters but less than ten centimeters, confined to the kidney. Stage IIB refers to a tumor with a maximum diameter greater than ten centimeters, but still confined to the kidney. In the case of stage II kidney cancer, although it is an early stage, curative treatment can be achieved through surgery. Therefore, if diagnosed with stage II kidney cancer, it is vital to pursue aggressive treatment.
How many centimeters is kidney cancer in the early stage?
Generally speaking, kidney cancers smaller than 4 centimeters are usually considered early stage, but it still depends on individual circumstances, such as whether the tumor has spread or metastasized, and the malignancy level of the tumor cells. Thus, assessing whether it is early or advanced stage requires consideration of these specific factors, and it cannot be simply determined by size alone.
Post-nephrectomy care for renal cancer
Postoperative care measures for kidney cancer primarily include observing the patient's vital signs. After a radical nephrectomy for a large renal tumor, a significant amount of tissue is removed including the kidney, surrounding adrenal fat, and lymph nodes at the renal hilum, which results in larger surgical wounds and potentially more bleeding. Therefore, it is crucial to closely monitor for signs of bleeding and ensure that transfusions and fluid administrations are unobstructed. Secondly, careful observation and management of the wound drainage tubes are required. Thirdly, for radical nephrectomies, once the patient is past the anesthesia phase and the blood pressure is stable, a semi-reclined position can be adopted. Patients who have undergone partial nephrectomy should remain in bed for one to two weeks to prevent further bleeding, and kidney functions should be monitored. Additionally, attention should be paid to symptoms such as breath holding and difficulty in breathing. Postoperative feeding should commence once gastrointestinal function is restored; thereafter, nutrition should be enhanced to boost bodily resistance. Calming medications may be appropriately used to ease pain, facilitating movement, effective coughing, and expectoration.
