What will happen to prostate cancer in the end?

Late-stage prostate cancer may present symptoms such as bone metastasis, difficulty urinating, and pain, and may ultimately be life-threatening due to organ failure or severe complications. The development of the disease is mainly related to factors such as tumor stage, pathological grade, and treatment timing.

1. Bone metastasis:

About 90% of patients with advanced prostate cancer will develop bone metastases, which are commonly found in the spine, pelvis and ribs. Cancer cells destroy bone, leading to pathological fractures and hypercalcemia, manifested as persistent bone pain and limited activity. Radionuclide therapy combined with bisphosphonate drugs can relieve symptoms, and targeted drugs such as radium-223 can selectively act on bone metastases.

2. Urinary system damage:

Tumor compression of the urethra or invasion of the bladder neck can cause progressive dysuria, urinary retention, and in severe cases, hydronephrosis. May be accompanied by hematuria, urinary incontinence, or recurrent urinary tract infections. An indwelling ureteral catheter or cystostomy is required. In advanced patients, ureteral stent implantation can be considered to relieve obstruction.

3. Nerve compression symptoms:

When spinal metastases compress the spinal cord or nerve roots, numbness, weakness or even paraplegia may occur in the lower limbs. Cauda equina syndrome manifests as perineal paresthesia and incontinence of urine and feces. Urgent vertebral decompression surgery combined with radiotherapy is required, and glucocorticoids can reduce neuroedema.

4. Whole body consumption:

Tumor progression leads to a state of cachexia, manifested by sudden weight loss, muscle atrophy, and extreme fatigue. Inflammatory factors secreted by cancer cells cause metabolic disorders, and patients often suffer from anemia and hypoalbuminemia. Nutritional support therapy combined with progesterone drugs can improve appetite.

5. Multiple organ failure:

Respiratory failure caused by lung metastasis, liver failure caused by liver metastasis, or disseminated intravascular coagulation caused by extensive metastasis may occur in the end stage. At this time, palliative care is the main focus, including symptomatic measures such as analgesic pumps to control pain and oxygen therapy to relieve dyspnea.

It is recommended that patients with advanced disease maintain moderate activities to prevent deep vein thrombosis and consume 1.2-1.5 grams/kg of high-quality protein every day. Pelvic floor muscle training can be performed to improve urinary function, and a three-step analgesic program can be used for pain management. Regularly monitor blood routine, liver and kidney function, and bone metabolism indicators. If severe bone pain or neurological symptoms occur, seek medical attention immediately. Psychological support is crucial to improving quality of life, and family members should be involved in pain assessment and care decisions.
