Reasons for the low resection rate of pancreatic cancer
The resection rate for pancreatic cancer is relatively low because the pancreas is located behind the peritoneum in a deep position. In the early stages of pancreatic cancer, there are often no specific clinical symptoms. Therefore, by the time pancreatic cancer is detected in patients, it is usually already in the advanced stages. The pancreas is surrounded by blood vessels and nerves. Therefore, if it is found in the late stage, the surgical difficulty is very high, making it difficult to remove surgically, which is why the surgical resection rate for pancreatic cancer is low.
What are the symptoms of bone metastasis from prostate cancer?
Bone metastasis is the most common site of metastasis for prostate cancer, with the lumbar vertebrae being the most common site. Eighty percent of bone metastases in prostate cancer are osteoblastic changes. The main symptoms caused by bone metastasis are bone pain, pathological fractures, anemia, and if the spinal cord is compressed, it can cause paralysis of the lower limbs, weakness, incontinence, and other symptoms.
androgen deprivation therapy for prostate cancer
Androgen deprivation therapy for prostate cancer includes surgical castration, which can quickly and continuously reduce levels to very low levels. The second is medical castration, which involves the use of analogs of luteinizing hormone-releasing hormone. Currently available products include leuprolide, goserelin, and triptorelin. Third, estrogen therapy, with diethylstilbestrol being the most common estrogen treatment. Surgical castration, medical castration, or estrogen therapy offer similar progression-free survival rates in patients with tumor-related outcomes.
The most common clinical manifestations of bladder cancer
The most common clinical manifestations of bladder cancer include: one initial clinical presentation is hematuria, which typically appears as painless, intermittent gross hematuria, sometimes it can also manifest as microscopic hematuria. The hematuria may occur only once or last from one day to several days, and it can subside or stop on its own. The color of the hematuria can be light red, possibly dark brown, generally dark red. The amount of bleeding and the duration of the hematuria are not necessarily proportional to the malignancy degree, size, scope, and number of the tumor. Additionally, bladder cancer patients can experience symptoms of bladder irritation, such as frequent urination, urgent urination, painful urination, and difficulties in urination, etc.
Commonly used drugs for endocrine treatment of prostate cancer
The purpose of endocrine therapy for prostate cancer is to reduce the concentration of androgens in the body, inhibit the synthesis of androgens originating from the adrenal glands, inhibit the conversion of testosterone to dihydrotestosterone, or block the binding of androgens to their receptors, thereby inhibiting or controlling the growth of prostate cancer cells. The medications include a luteinizing hormone-releasing hormone analogue, with representative drugs being leuprorelin, goserelin, and triptorelin. There is also an androgen-blocking drug, including steroidal drugs with representative drugs like cyproterone acetate, and non-steroidal drugs with representative drugs like bicalutamide and flutamide. Additionally, there are estrogens, with the most common being diethylstilbestrol.
Which department do you go to for lymphoma?
If a lump is found on the neck and lymphoma is suspected, the first step is to consult with the head and neck surgery department. The lymphoma lesion will be surgically removed by the department, and then sent for a pathological examination. If lymphoma is confirmed, the next steps involve treatment by the oncology department, hematology department, or radiation therapy department.
