Nursing Diagnoses

This week I am going to post 5 nursing diagnoses for a man with prostate cancer. I found these from a book called "Medical-Surgical Nursing: Assessment and Management o Clinical Problems" and another called, "Nursing Diagnosis Handbook: An Evidence-Based Guide to Planning Care."

1) At risk for acute pain related to surgery, prostatic enlargement, bone metastasis, and bladder spasms.

2) At risk for anxiety related to uncertainty of disease process, treatments, and/or outcome on lifestyle and sexual function.

3) At risk for imbalanced nutrition related to less than body requirements related to decreased oral intake due to anorexia, nausea and vomiting caused by cancer or its treatment

4) At risk for sexual dysfunction related to effects of therapy

5) At risk for urinary retention and impaired urinary elimination related to urethral obstruction from the prostate gland.

Here is a more detailed chart I created for the nursing diagnosis of anxiety:

Nursing Care of Patients with Prostate Cancer

This week I will be talking about the nursing care for patients with prostate cancer. There are many important roles that nurses can have, especially since a patient with prostate cancer can be treated in many different ways. There are nursing care and education implications for each decision your patient makes. I am creating this chart based on a lecture on prostate cancer I received  Dr Dr. Donna Berry, an affiliate professor for the University of Washington Biobehavioral Nursing and Health Systems department.

To treat or not to treat?

I am going to re-post this video so that you can recall the steps made in a prostate cancer diagnosis: A physician will do a rectal exam where he feels the prostate and/or a PSA test (looking at the amount of PSA in the blood to see if it is abnormal, and assessing if the levels are due to cancer growth). A biopsy may also be done (where the doctor will use technology to gather tissue samples of the prostate and look closer at the cells).

Once a man is diagnosed with prostate cancer, there are several options available to him. Because there is no way to determine with certainty how aggressive a man's prostate cancer will be, deciding what to do can be a difficult decision. If you are diagnosed, you should learn about all of your options and decide which are best for you and your particular situation. Here are the main treatment options:

1) Active Surveillance- This means that no treatment will be done, and instead the prostate will be monitored over time so that if any significant changes happen in the future, perhaps then treatment may be considered. PSA tests and digital rectal exams (DREs) will be performed by a doctor at different scheduled times (usually 4 times per year). Many men who have prostate cancer that is confined to the prostate gland and hasn't spread choose this option.

2) Surgery- some men choose to have their prostate gland removed.  Complications from this can include urinary incontinence and sexual dysfunction

3) External Radiation Therapy-external radiation beams can be used to target specific areas of cancer to try and kill them. This is commonly done every week day for about 6 weeks, 15 minutes at a time. Side effects can include feeling very tired, sexual dysfunction, bladder irritation for short periods of time, and bowel dysfunction if the radiation beams hit the bowel or bladder.

4) Internal radiation therapy- "seeds" with radiation inside of them are planted in the prostate. This is also called "Brachytherapy." An irritated bladder and sexual dysfunction are possible side effects. Something else to note is that if a man has these seeds in him, he cannot be too close to women who are pregnant or could become pregnant, nor should he be near infants. The radiation can be very damaging to these groups of people, so men with wives of childbearing age and young children or grandchildren, for example, might not want to choose this option.

5) Chemotherapy-the use of medicine to kill cancer cell

I want to emphasize that there is no one "right" way to treat prostate cancer. This can be difficult, because oftentimes when people (myself included!) find out they are sick with something, they want a roadmap. They want an expert who can tell them what to do and explain exactly how different treatments will affect them. However, we don't know enough about prostate cancer to be able to answer these questions. Predicting prognosis is very difficult. The most important thing is that you talk with your doctor about all of the options available and weigh the pros and cons of each. Doctors can give you input and answer your questions, but ultimately it should be your informed decision. 

Here is a video that discusses treatment options and when someone might choose them:

Signs and Symptoms

I made a quick chart showing the most common symptoms that men with prostate cancer experience. Note that most men with prostate cancer will have no symptoms whatsoever. Equally important to remember is that the symptoms listed below can be caused by other things besides prostate cancer as well. In other words, the symptoms are not specific only to prostate cancer.

I received this information from a lecture in my nursing program given by Dr. Donna L Berry, PhD, AOCN (1). 

Here is a video from Cancer Research UK that explains this as well. It also talks a bit about tests for prostate cancer diagnosis, which will be my next topic.

Disease Progression

We cannot say with certainty what causes prostate cancer. As I discussed in a prior post, we know that age is a significant risk factor, and that certain groups of people are more likely to get prostate cancer. The American Cancer Society has a comprehensive article on prostate cancer, and they say that it is suspected to start with small changes in prostate gland cells and grow from there. They also mention that certain inherited genes can increase risk. Other risk factors like smoking and having prostate inflammation are believed to contribute to risk.

Prostate cancer will start out in the prostate itself. According to the American Cancer Society, the next place it will spread is nearby tissue and lymph nodes. Here is a picture of the lymph nodes close to the prostate gland (in green).

Once the cancer enters the lymph nodes, it can spread through the lymphatic system to other parts of the body, and most commonly will go first to the bones. This picture gives you a general idea of what the lymphatic system looks like (in green). The green circles are lymph nodes (they are everywhere!), and the green lines are the pathways that lymph (the fluid that moves around in this system) travels through to reach lymph nodes. Looking at this picture, you can see how cancer cells near the prostate gland could hitchhike and spread to anywhere in the body.

Prostate cancer especially likes to spread to the spine, ribs, skull, and the top ends of the bones of your arms and legs. As you might remember from one of my first posts, cancer that has spread this far in the body is called Stage 4 (the most advanced stage). This stage of cancer is the most deadly.

Note: I have just briefly explained how prostate cancer can spread to its most deadly stage. However, in most men, prostate cancer grows very slowly. Most men with prostate cancer will not die from it, because it is so slow growing that it will remain within the prostate gland, not causing much harm or spreading to other sites of the body. Some people have more aggressive (fast-growing and spreading) prostate cancer than others, which is more dangerous, but there is no sure way to tell what a person's outcome will be with certainty. 

You might ask, "so I know that cancer is bad, and that if it spreads this is bad, but I don't fully understand why. How exactly can it kill someone?" Here is a bit more information on how cancer takes over the body:

In the words of Cancer Research UK, cancers (like prostate cancer) can take over parts of the body that we need in order to survive. Cancer cells destroy the once normal tissues they invade so that they can no longer do what they were made to do. For example, if a cancer (like prostate cancer) moves to the lungs, a person's lungs will not be able to take in oxygen, which we need in order to survive. Also, our bodies are very complex and when they are healthy, they maintain a tightly controlled balance of chemicals and nutrients. Changes in one area of the body will affect other areas as well. Our bodies house complex, interconnected systems that depend on each other. So, for example, if we have cancer in our bones, our bones will become damaged and release Calcium into our blood. Bones store calcium, which is needed for survival, but healthy bones only release their calcium when we need them to. In cancerous bone, it is damaged and releases its calcium as a result, more than we need. When this keeps happening, over time it is too much for our bodies to handle and it can cause death. Other cancers can make substances that harm the body.

Who has prostate cancer? What are the trends?

This week I am going to talk about a big fancy word called the "epidemiology" of prostate cancer in the US. This just means I am going to look at where prostate cancer is and which groups of people are most likely to have it. I am using the National Cancer Institute's website primarily as my source of information as well as the CDC.

How many men get it? How many die from it each year?

Prostate cancer is one of the most common cancers among men, and 1 in 7 will be diagnosed with it (hence the title of my blog, "1 in 7"). However, if caught early, prostate cancer has high treatment success (Cancer Treatment Centers of America 2015).

According to the National Cancer Institute, last year (2014) there were around 233,000 new cases of prostate cancer reported (note how I say reported. There still might be many more people with it who have not been diagnosed or who were missed/not accounted for in the statistics). There were 29,480 estimated deaths from prostate cancer. Additionally, if we look at trends over time (the latest data availble for trends is from 1992-2011), we see that new prostate cancer diagnoses are going down, and the amount of deaths from it are lower than the amount of people newly found to have it.

National Cancer Institute. SEER Fact Sheets: Prostate Cancer:"At a Glance." Retrieved from http://seer.cancer.gov/statfacts/html/prost.html

Prostate cancer is slow-growing and men with it will often not die from it. They will often die from another cause instead of prostate cancer. Thus, there are high numbers of new cases but much fewer deaths from it. It often does not spread to other parts of the body, but when it does, we see higher  mortality rates. Here is a graph that shows the percentage of people who are expected to still be alive 5 years after their stage of diagnosis (it does not mean they are expected to live only 5 years):

How old are most people who have it?

Prostate cancer is a cancer of men, and risk increases with age. Most of the new diagnoses are made in men ages 65-75. Here is some food for thought about reporting diagnoses: people can only be diagnosed if they are screened for prostate cancer in the first place, so there might be more men with prostate cancer than we are aware of because they have not been screened.

National Cancer Institute. SEER Fact Sheets: Prostate Cancer: "Who Gets This Cancer?" Retrieved from http://seer.cancer.gov/statfacts/html/prost.html

Who is at the highest risk?

Also according to the national cancer institute, African American men as well as men whose fathers have or had prostate cancer are at the greatest risk (family history plays a role). Here is a graph that looks at risk by race. It looks at the number of newly diagnosed people per every 100,000 in the population. So, for example, if we look at men of Asian/Pacific Island descent in the United States, for every 100,000 of this subpopulation, 79.3 will be newly diagnosed with prostate cancer each year. They got this data from compiling data from 2007-2011.

National Cancer Institute. SEER Fact Sheets: Prostate Cancer: "Who Gets This Cancer?" Retrieved from http://seer.cancer.gov/statfacts/html/prost.html

What does the distribution look like in the United States?

This graph by the CDC looks at the percentage range of men who were newly diagnosed with prostate cancer in each state in 2011 (the most recent state-comparing data I found)

The Centers for Disease Control and Prevention. 2011. Rates of Getting Prostate Cancer By State. Retrieved from http://www.cdc.gov/cancer/prostate/statistics/state.htm.

What are some of the burdens of prostate cancer?

Economic: Cancer treatment is expensive, and prostate cancer treatment is no exception. Costs involved include screening, treatment, follow-up doctor's appointments, possible hospitalization, medication, etc. I am going to try and find more recent data than this, but am having difficulty. So for now, according to Pfizer (2005), the average yearly health care spending per person with prostate cancer (directly related to the prostate cancer) was about $3500 and the cost of comorbidities was about $8500 (Pfizer 2005). I feel like this cost would be higher than this today, however, so I will update this when I find better information. The total cost in the US for prostate cancer and comorbidity spending was nearly $13 billion.

Personal: If a person decides to undergo treatment, there will be costs involved besides the treatment itself and consultations such as transportation, a person might have to take time off of work depending on their specific situation, or the treatment of other problems that may arise such as depression or pain can cost money as well.

Emotional: Anyone diagnosed with a chronic disease will likely be at a greater risk for depression or grief. There may be adjustments in their lives emotionally, physically, and within their family and friendships.

Prostate Cancer: What is it? What are its stages?

Prostate cancer is a cancer that starts in the prostate gland. To briefly explain its role, the prostate gland (which men have) helps with male sexual function. It makes a fluid that mixes with sperm to help produce semen during ejaculation. Here is a picture of where the prostate is (in this picture it is in the center of the black circle):

Prostate cancer is when the DNA of prostate gland cells mutates and no longer functions normally. Here are its stages according to TNM staging:

I: The cancer is in the prostate only (the tissue from which it came)

II: The cancer is more advanced, but has not quite spread outside of the prostate. We say it is still "encapsulated," or contained within the "capsule"/outer margins or borders of the prostate.

III. The cancer has spread beyond the outer layers/capsule of the prostate

IV. The cancer has spread to nearby tissues and organs

The TNM staging stops here, but keep in mind that the next step after this would be that the cancer has spread to other body parts, such as the brain, lungs, or bones. I will go into more detail on how a doctor determines the stage and what each one means in another post when the time comes, but this is just an introduction to the concept.

Here is a video about what cancer and prostate cancer is. It talks about some things I have not discussed yet (such as possible causes), so I recommend watching up until that point:
