Outlook Once Cancer Has Spread To The Bones

What is advanced prostate cancer?

The research on cancer metastasis is rapidly growing. As researchers better understand the mechanisms of bone metastasis, new drugs and other treatments are being developed. These target particular processes in cells involved in how the cancer cells invade and grow in bones.

The use of nanoparticles to deliver drugs is very encouraging. These tiny particles are able to deliver drugs to the bone with minimal toxicity to the person with cancer.

Rapidly treating bone metastasis can lead to a

Eating Problems And Weight Loss

Some men with advanced prostate cancer have problems eating, or dont feel very hungry. You might feel or be sick. These problems may be caused by your cancer or by your treatments. Being worried about things can also affect your appetite.

Problems eating or loss of appetite can lead to weight loss and can make you feel very tired and weak. Advanced prostate cancer can also cause weight loss by changing the way your body uses energy.

What can help?

If you feel sick because of your treatment, your doctor can give you anti-sickness drugs. Steroids can also increase your appetite and are sometimes given along with other treatments.

Try to eat small amounts often. If youre struggling to eat because of nausea , try to avoid strong smelling foods. Cold foods tend to smell less, or it may help if someone cooks for you. Try to eat when you feel less sick, even if its not your usual mealtime. Fatty and fried foods can make sickness worse. Drink plenty of water, but drink slowly and try not to drink too much before you eat.

Tell your doctor if you lose weight. They can refer you to a dietitian who can provide advice about high calorie foods and any supplements that might help. It can be upsetting for your family to see you losing weight, and they may also need support. Macmillan Cancer Support and provide support and information about eating problems in advanced cancer.

Back Pain From Cancer

Rarely, it may be the first manifestation of cancer, says a paper in the Journal of General Internal Medicine .

The study authors point out that out of 1,975 walk-in patients at a clinic, only 13 were found to have cancer as a cause of their back pain.

Certain findings correlate to this, but these findings certainly dont automatically mean cancer:

At least 50 years of age

Previous history of cancer

Pain lasting longer than a month

No improvement with conservative therapy

Whats scary is that the paper says that metastatic cancer, when causing back pain, may not always cause other symptoms.

When cancer causes back pain, its more frequently in the lower region. Thus, pain specifically in the middle back, from this disease, would be even rarer.

Quite simply, pain in the back, be it low, middle or upper, has MANY causes including inflammatory bowel disease, irritable bowel syndrome, gastroesophageal reflux disease , fibromyalgia, aortic disease, imminent heart attack, premenstrual syndrome, benign ovarian cysts and overdoing it in a yoga class.

How Do You Know If Prostate Cancer Has Spread

Prostate cancer that has spread to the liver, intestines, or bones of the abdomen and pelvis can usually be found with a CT scan. Cancer which has spread to the lymph nodes can sometimes be detected if the lymph nodes have become enlarged.

What is the prognosis for prostate cancer that has spread to the bones?

There is currently no cure for advanced prostate cancer, but advances in treatments are extending life expectancy and improving quality of life. The ACS state that the 5-year relative survival rate for individuals with prostate cancer that has spread to distant lymph nodes, organs, or the bones is 29 percent.

What Are The Signs That Prostate Cancer Has Spread

Metastatic prostate cancer

Men diagnosed with prostate cancer are already on a care plan or another at the recommendation of their doctors. This procedure most likely starts from an extensive set of tests in order to determine how advanced their form of prostate cancer is and the speed at which their tumor grows.

Nonetheless, there are certain visible signs that indicate the fact that cancer cells have already started spreading outside the prostate gland. Keep in mind that prostate cancer manifests differently from case to case. Therefore, prostate cancer patients might experience some of the following signs or none at all.

The Underlying Molecular Mechanisms In Prostate Cancer Bone Metastases

Various types of prostate cancer cell lines, including LuCaP 23.1, LNCaP, C4-2, and IGR-CaP1, were utilized as prostate cancer models. The LuCaP 23.1 and LNCaP cells are highly sensitive to androgen . The C4-2 cell lines showed features of reduced androgen sensitivity and increased metastatic capability . In the androgen-sensitive prostate cancer cell lines, the downregulation in androgen receptor expression reduced AR-mediated transcription and cell growth. Meanwhile, the knockdown of AR expression had a marked effect on AR-mediated transcription and cell growth in the androgen-insensitive prostate cancer cell lines . The expression of AR is an important regulator of prostate cancer cell growth and development at the early stage. However, prostate cancer progresses to castration-resistant prostate cancer at the later stage. Thus, possible correlation between AR expression and the signaling molecules involved in prostate cancer bone metastasis could be considered. On the other hand, the IGR-CaP1 cell line represents a unique model recapitulating widespread bone metastasis with mixed osteoblastic and osteolytic bone lesions that resemble the conditions observed in patients .

Treatment For Metastatic Cancer

Radical prostatectomy and radiation therapy are generally used to treat localized prostate cancer. However, for patients that eventually develop locally advanced or metastatic cancer, hormone or radiation therapy may be required.

Hormone therapy is used to inhibit the growth of prostate cancer cells.

More than 85% of men who receive hormone therapy develop metastatic castration-resistant prostate cancer within 3 years of hormone treatment. This is caused by prostate cancer cells adapting to low androgen levels.

Symptoms Of Prostate Cancer Spread To The Lymph Nodes

Metastatic prostate cancer in the spine bones

Lymph nodes are part of a system of tubes and glands in the body that filters body fluid and fights infection.

There are lots of lymph nodes in the groin area, which is close to the prostate gland. Prostate cancer can spread to the lymph nodes in the groin area, or to other parts of the body. The most common symptoms are swelling and pain around the area where the cancer has spread.

Cancer cells can stop lymph fluid from draining away. This might lead to swelling in the legs due to fluid build up in that area. The swelling is called lymphoedema.

The Role Of The Rank/rankl/opg System

The receptor activator of nuclear factor-kappa B /RANKL/OPG system is a key molecular system discovered to regulate the bone modeling and remodeling process. Osteoprotegerin is a decoy receptor produced by osteoblasts that blocks the association between RANKL and RANK, thus inhibiting osteoclastogenesis and increasing bone mass. Apart from controlling the normal bone metabolism, this system also plays an essential role in pathological bone metabolism, such as metastatic disease in bone.

Taken together, these previous findings reiterate that: OPG may be beneficial in preventing osteolytic lesions but overexpression of OPG leads to osteoblastic lesions, and a high level of RANKL expression causes osteolytic lesions, thus RANKL blockade will potentially limit the formation and progression of osteolytic lesions. Hence, maintenance of a balanced profile between OPG and RANKL may represent a potential therapeutic strategy for interfering with prostate tumor metastases and progression to bone.

Where Does Prostate Cancer Spread

One of the most recent studies involving a nationwide sample of near 75,000 patients considered the answer to this question.

The most common sites of metastasis in advanced prostate cancer included :

  • Local spread: We should first consider local spread, which comes before metastasis. We also call it locally advanced prostate cancer. Local spread is found in the pelvic organs, rectum, and seminal vesicles. Patients with metastasis almost always had local spread before leaving the pelvis.
  • Bone metastasis: This accounts for 85% of metastasis sites. The bone matrix is a very common target organ. It attracts cancer cells as a blood and nutrient-rich area where they can easily thrive.
  • Metastasis in distant lymph nodes: They are lymph nodes located anywhere but the pelvic region. It accounts for 10% of metastasis sites. It is a sign of lymphatic spread instead of blood-borne spread.
  • Liver metastasis: Another 10% of these patients had metastasis in the liver.
  • Metastasis in thoracic organs: This is mainly lung metastasis. It accounts for 9% of metastasis sites in prostate cancer patients.

According to this study, one out of five patients with advanced disease had more than one metastatic site.

What Questions Should I Ask My Doctor

If you have a metastatic spinal tumor, you may want to ask your doctor:

  • Will I have different treatment for the metastatic spinal tumor than for the original tumor?
  • Will cancer spread to other areas of my body?
  • What symptoms of other metastases should I watch out for?
  • How can I stay as healthy as possible with a metastatic spinal tumor?
  • How will treatment affect my work and daily life?

How To Tell If Your Cancer Has Metastasized

Metastatic prostate cancer

Prostate cancer metastasis may be suspected if you have specific symptoms such as new lower back pain or elevated liver enzymes. These may be signs your cancer has spread to your spine or your liver, respectively. If your prostate-specific antigen levels continue to rise despite treatment, especially if they are rising particularly fast, this may be a sign that cancer is metastasizing somewhere in your body.

Bone Metastases In Patients With Metastatic Crpc

In approximately 80% of PCa patients bone metastases represent the initial and main metastatic site and are an important prognostic factor . About half of PCa patients with untreated bone metastases will experience at least one SRE over the period of 2 years .

The knowledge of the mechanisms underlying the development of bone metastases and the correlation between bone and cancer cells is of special importance with regard to the different therapeutic options for the management and prevention of SREs. Bone metastases in PCa are frequently osteoblastic, however an osteolytic element has also been confirmed in various reports , and the majority of lesions tend to be heterogeneous .

In clinical trials of bone-modifying agents for the treatment of bone metastases, the incidence of SREs was used as a composite primary endpoint , and they are recognized by the US Food and Drug Administration as a suitable endpoint to assess the efficacy of agents for the treatment of bone metastases in patients with cancer .

    How Do Doctors Find Metastatic Prostate Cancer

    When you are diagnosed with prostate cancer, your doctor will order tests such as:

    • X-rays
    • MRI scans
    • PET scans

    These tests may focus on your skeleton and in your belly and pelvic areas. That way doctors can check for signs that the cancer has spread.

    If you have symptoms such as bone pain and broken bones for no reason, your doctor may order a bone scan. It can show if you have signs of cancer spreading to your bones.

    Your doctor will also ask for blood tests, including a check of PSA levels, to look for other signs that the cancer is spreading.

    PSA is a protein made by the prostate gland. A rise in PSA is one of the first signs your cancer may be growing. But PSA levels can also be high without there being cancer, such as if you have an enlarged prostate, a prostate infection, trauma to the perineum, or sexual activity.

    Primary And Metastatic Spinal Tumors

    Intermittent Hormone Therapy for Prostate Cancer 101 | Ask a Prostate Expert, Mark Scholz, MD

    Primary spinal tumors are those that originate in the spine. They are relatively rare, typically benign and represent a small percentage of spinal tumors. Malignant tumors may also originate in the spine, although more often they spread to the spine from elsewhere in the body.

    Metastatic spinal tumors are those that have spread to the spine from other areas of the body. If a tumor is able to spread, this usually means it is malignant. Between 30 and 70 percent of cancer patients develop metastatic spine cancer during the course of their disease. Lung, prostate, and breast cancers are the three most common cancers that tend to spread to the spine.

    Bone Loss From Prostate Cancer Treatment

    Testosterone, the male sex hormone, fuels the growth of prostate cancer but it also is crucial to bone health. Treatment of prostate cancer with hormone therapy, also called androgen deprivation therapy , blocks the production of testosterone which stops or slows the growth of the cancer. Without testosterone, bones can become weak and break more easily. When a man is on ADT, recovery from a bone fracture takes longer than for other men. It is especially important for men taking ADT to speak with their doctor about how to plan for and manage the bone loss before a problem arises. Bone strength can also be decreased as a result of radiation and chemotherapy used to treat prostate cancer.

    Fortunately there are ways to strengthen and repair your bones including medicines and lifestyle changes.

    • Bisphosphonates can prevent the thinning of the bone and help make them stronger
    • Oral bisphosphonates include Fosamax and Actonel
    • The intravenous bisphosphonate is Zometa
    • Strive for a healthy diet and make sure to get enough calcium and vitamin D
    • When exercising, include weight bearing and muscle strengthening exercises
    • Avoid tobacco and excessive alcohol


    What Is My Risk Of Developing Mscc

    MSCC isnt common, but you need to be aware of the risk if your prostate cancer has spread to your bones or has a high risk of spreading to your bones. Your risk of MSCC is highest if your prostate cancer has already spread to your spine.

    Speak to your doctor or nurse for more information about your risk of MSCC.

    Treatments For Prostate Cancer Spread To Bones

    If prostate cancer spreads to other parts of the body, it nearly always goes to the bones first. Bone metastasis can be painful and can cause other problems, such as fractures , spinal cord compression , or high blood calcium levels, which can be dangerous or even life threatening.

    If the cancer has grown outside the prostate, preventing or slowing the spread of the cancer to the bones is a major goal of treatment. If the cancer has already reached the bones, controlling or relieving pain and other complications is also a very important part of treatment.

    Treatments such as hormone therapy, chemotherapy, and vaccines may help with this, but other treatments specifically target bone metastasis and the problems it may cause.

    Types Of Imaging Studies

    If your healthcare provider suspects your cancer might be spreading, they will likely order more imaging tests. A common imaging workup may include a bone scan and a CT scan of the abdomen and pelvis. An MRI might be done as well. Some research centers are also using magnetic MRIs or PET scans to further refine the staging of prostate cancer.

    So What Are The Warning Signs Of Prostate Cancer

    Unfortunately, there usually arent any early warning signs for prostate cancer. The growing tumor does not push against anything to cause pain, so for many years the disease may be silent. Thats why screening for prostate cancer is such an important topic for all men and their families.

    In rare cases, prostate cancer can cause symptoms. Contact your doctor for an evaluation if you experience any of the following:

    • A need to urinate frequently, especially at night, some- times urgently
    • Difficulty starting or holding back urination
    • Weak, dribbling, or interrupted flow of urine
    • Painful or burning urination
    • Blood in the urine or semen
    • Pressure or pain in the rectum
    • Pain or stiffness in the lower back, hips, pelvis, or thighs

    Remember: urinary symptoms dont necessarily mean you have cancer. Prostatitis or BPH are benign diseases but can cause similar symptoms and are very common.

    What about difficulty in having an erection? Again, this is most likely not caused by cancer but by other factors such as diabetes, smoking, cardiovascular disease, or just plain getting older.

    That said: Symptoms are symptoms, and no matter whats most likely to be causing them, you should get them checked out by a doctor.
