How to treat bone metastases from prostate cancer?
The treatment of bone metastases from prostate cancer can include first-line hormonal therapy. During hormonal treatment, bisphosphonates can be used in conjunction to increase bone density. Additionally, external radiation therapy can improve localized bone pain. Patients with multiple bone metastases or bone pain can undergo radionuclide therapy. Another method is the use of analgesic drug therapy, which is also a main approach to alleviate pain from bone metastases of prostate cancer.
Late-stage prostate cancer with bone metastases: how long can one survive?
Bone metastasis is the most common site of metastasis for prostate cancer. If prostate cancer has metastasized to the bones, it means it is not in its early stages but has entered the advanced stages. However, this type of tumor is not like others with a higher degree of malignancy. If it has a good sensitivity to hormone therapy, after our standardized treatment, the survival time can still be quite long.
The difference between prostate cancer and prostatitis
Prostatitis and prostate cancer have different causes. Prostatitis is caused by the invasion of pathogens into the prostate, whereas prostate cancer is mostly related to genetics, lifestyle and dietary habits, and genetic mutations. Their clinical manifestations are inconsistent; prostatitis mainly presents as pain or abnormal urination, while prostate cancer primarily shows symptoms of compression and metastasis. Of course, their treatment methods are also different.
Prostate Cancer Treatment Options
How is prostate cancer treated? The choice of treatment plan should be based on a comprehensive consideration of the patient's clinical stage, age, overall health, and expected lifespan. For example, in the early stages of prostate cancer, one can choose postoperative radical radiotherapy after prostatectomy. For locally advanced prostate cancer, radiotherapy, intensified radiotherapy combined with endocrine therapy can be chosen. For metastatic prostate cancer, endocrine therapy is mainly used, and chemotherapy can be adopted for those who are ineffective or fail endocrine therapy.
What causes prostate cancer?
The current causes of prostate cancer are not completely understood, but a large amount of research indicates that genetic and environmental factors play a significant role. Dietary factors, such as the intake of a large amount of unsaturated fatty acids, vasectomy, smoking, obesity, and alcohol consumption, also increase the risk of developing prostate cancer. Overall, the occurrence and development of prostate cancer are related to various factors, including both internal causes in the patient and the influence of external factors.
How can esophageal cancer be diagnosed?
The diagnosis of esophageal cancer is primarily based on symptoms. In the early stages, symptoms are generally nonspecific or only mild and typically do not attract the patient's attention. In the mid to late stages, the most common symptom is progressive difficulty swallowing. Additional diagnostic methods include esophageal radiography, MRI, and CT scans. Moreover, cytological diagnosis, endoscopic ultrasound of the esophagus, direct endoscopic examination and pathological sampling under endoscopy are utilized. The gold standard for confirmation still requires pathological or cytological diagnosis.
What are the symptoms of stomach cancer?
Gastric cancer can cause pain in the upper abdomen. If the condition gradually worsens, it can manifest as persistent pain, postprandial fullness and vomiting, belching, and lack of appetite; upper gastrointestinal bleeding, manifesting as vomiting blood, blood in the stool, and black stools; there can also be difficulty swallowing, weight loss and anemia. If bone metastasis occurs, it can manifest as bone pain and pain in the lower back. If a large amount of ascites appears, it can lead to abdominal distension, with shifting dullness detectable on percussion. If liver metastasis occurs, it can manifest as jaundice, and enlargement of the supraclavicular lymph nodes can also occur.
How is prostate cancer detected?
Digital rectal examination combined with PSA testing is currently recognized as the best screening method for the early detection of prostate cancer. Currently, systematic prostate needle biopsy is the most reliable method for diagnosing prostate cancer. In addition, prostate cancer MRI plays an important role in clinical staging. There is also a whole-body nuclear bone marrow scan that can detect the most common metastatic sites of prostate cancer, including bone metastases.
What are the causes of prostate cancer?
At present, there are many factors that cause prostate cancer, but its exact etiology remains unclear. It may be related to genetic factors, gene changes, prostate gonococcal and chlamydial infections, intensity of sexual activity, and the influence of hormones. Additionally, dietary habits, long-term consumption of high-fat foods, and occupational hazards, such as excessive exposure to chromium, may also be related to the development of the disease.
Where can prostate cancer metastasize to?
When prostate cancer invades surrounding tissues and structures, it can cause a variety of clinical symptoms, including urinary irritation, urinary obstruction, urinary incontinence, sciatica, erectile dysfunction, etc., and can compress causing unilateral or bilateral hydronephrosis. In severe cases, when the tumor invades the rectum, it can cause difficulty in defecation or colon obstruction. When the cancer metastasizes to the bones, it can cause bone pain and pathological fractures, and may also spread to the lungs.
