Actos and Bladder Cancer : Traditionally, the surgery is performed through a lower abdominal incision in the midline from just below the umbilicus (i.e., “belly button”). Hospitalization for this procedure is generally between 5 and 10 days, and up to 6 weeks are needed for complete recovery. In recent years minimally invasive surgical approaches that replicate the technique of open radical cystectomy have been developed. Both laparoscopic and robotic-assisted radical cystectomies are currently being performed at highly specialized cen­ters. The principles of the surgery are the same, but the procedure is performed through smaller incisions using laparoscopic instruments. Using robotic assistance, your surgeon is able to perform complex operations with higher precision, under magnification. These approaches offer die potential advantage of a shorter recovery time, less blood loss, and less postoperative pain,

A pelvic lymph node dissection should be performed at the time of your surgery. This involves removal of the lymph node tissue in the most common areas of bladder cancer metastasis (spread of the cancer). The pelvic lymph node dissection has two important roles: to stage the cancer and to guide therapy. Individuals who are found to have cancer in the lymph nodes at the time of surgery generally require additional therapy such as chemotherapy. Studies have shown that up to 30 percent of patients with disease- positive lymph nodes who undergo a pelvic lymph node dissection will be free of disease at 5 years. Although there is debate among urologists as to exactiy how extensive ofapelvic lymph node dissection should be performed, there is no de­bate that one should be performed. Although a pelvic lymph node dissection can add an additional 30-90 minutes to your procedure time, there is little additional morbidity associ­ated when performed by an experienced surgeon.

Regardless of the approach, anyone who undergoes a radical cystectomy will require a form of urinary diversion because the bladder will no longer be there to store urine. This can have a significant psychological and functional impact on an individual’s quality of life. Patients are often hesitant to undergo definitive surgery because of the anxiety associated with long-term urinary diversion. There are two main types of urinary diversion: continent and noncontinent. Both forms require surgically removing a segment of bowel (most commonly the small bowel) from your gastrointestinal (GI) tract and plugging the ureter from each kidney into this segment of bowel to provide drainage of urine. Noncontinent diversions (ileal conduit) are those in which the piece of bowel is brought up through the abdominal wall to a stoma and the urine drains contin­uously into a drainage bag. This is die most common type of urinary diversion performed in the United States. This procedure requires approximately 8 to 10 centimeters (3 to 4 inches) of small bowel, which is far less than that used for continent urinary diversions. Although the obvious dis­advantage of this procedure is its lack of continence and need for a continuous drainage bag, it has less short- and long-term complications than that of the continent diver­sion. An external urinary drainage appliance is very well tolerated and patients adapt to them very quickly.

Actos and Bladder Cancer : This is what is usually called a “false-positive” test result. The test was positive in a case where it seems that it should have been negative. Any medical test has a cer­tain false-positive rate (usually very low). The problem with a false-positive result with urine cytology is that there is no way to guarantee the absence of cancer. It is always possible that the cancer is there, but we have not been able to find it yet. Sometimes it can hide in places such as the ureters or kidney where we cannot see as well. Other times, especially with carcinoma in situ, the diseased areas look normal through the cysto- scope but actually harbor serious disease. Because of this, one should never ignore a positive cytology result. Close to 80% of patients with a positive cytology but a negative evaluation will eventually be found to have a urologic malignancy.

For more information on Actos and Bladder Cancer follow us on our RSS Feeds.

The current recommendation for patients with a posi­tive urine cytology and a negative initial evaluation is to repeat the urine cytology 6 to 8 weeks later. Those patients with a negative cytology on the follow-up test do not need further evaluation. If the follow-up cytol­ogy is positive, however, careful evaluation should be undertaken, as most of these patients will eventually be found to have a malignancy. Your urologist may rec­ommend multiple small biopsies of the bladder to look for carcinoma in situ, a condition that is often associ­ated with positive cytology.

Although cytology has long been the gold standard for bladder cancer screening, including monitoring for recur­rences, it is far from perfect (see Question 33), and there is great interest in finding an even better test. Currently, at least four other markers are approved by the Food and Drug Administration (FDA), although none of them are clearly better than cytology. In addition to these four, many new tests are being developed. The four listed here are those that are currently available to patients. If you are considering a radical cystec­tomy, you want an individual who regularly performs that operation. A radical cystectomy is a complicated, time-consuming procedure that some urologists rarely or never perform. The old dictum “practice makes perfect” certainly applies here. Furthermore, if you are interested in the neobladder option for reconstruction of your urinary tract, you should make sure that the urologist is comfortable with that portion of the oper­ation. The neobladder adds complexity to the proce­dure for the surgeon, and not all urologists are well trained in this area. The urologist should know his or her own complication rate for the procedure and not just quote widely published rates for other surgeons. He or she should be comfortable and willing to discuss these rates with you.

Cancer can be a frightening word and disease no matter how you look at it. You want a physician who understands your fears and concerns and who is willing to take the time to help you make your management decisions. There is no good measure for this, but trust your instincts at your first meeting with a new doctor. Sometimes you may feel that it is necessary to get a second opinion. You may have concerns about the treatment recommendations or may worry that there are other options that have not been presented. If you ever feel that you have not received enough informa­tion or that you are uncomfortable with the treatment recommendations from your urologist and/or oncolo­gist, then it is appropriate to seek a second opinion.

Actos and Bladder Cancer: Due to the ease of obtaining voided urine specimens, bladder cancer is on the forefront of developing tumor markers. Drs. McNeil, Ekwenna, and Getzenberg take an in depth look at various tumor markers and molecular signatures of bladder cancer in Chap. 6. Although several new tumor markers for bladder cancer are discovered each year and are the subject of numerous review articles, only few reviews are written on the subject of healthcare cost associated with bladder cancer diagnosis, screening, and surveillance. Chapter 7 by Yair Lotan is devoted to the subject of cost associated with bladder cancer detection and surveillance in the general versus high-risk population and using noninvasive techniques such as hematuria detection and tumor markers.

Prognostic markers and molecular nomograms involving proteomics and genom­ics are highly researched and some of the new emerging areas in bladder cancer. In Chap. 8, Dr. Habuchi focuses on seven different classes of molecules ranging from cell adhesion molecules to genetic alterations, which have been investigated for pre­dicting disease progression, response to treatment (local versus systemic control of the disease),

and survival. Chapter 9 by Smith and Theodorescu dwells on a novel idea of molecular nomograms for personalized medicine. While Chap. 8 includes information on individual markers, this chapter focuses on multiplexing of molecular biomarkers to predict response to therapy. Of note is COXEN or Co-expression Extrapolation) algorithm that compares microarray gene expression profiles between cell lines and patient tumors to generate signatures predictive of drug sensitivity or resistance.

Bladder cancer being a complex disease, a practical guide that provides the nec­essary facts at the fingertips is very useful and Chap. 10 by Drs. Levy and Jones provides just that for the management of nonmuscle invasive bladder cancer. Specifically the chapter provides a succinct description of epidemiology, etiology, pathophysiology, clinical and diagnostic evaluations, available molecular markers for disease, as well as the current American Urological Association Guidelines Panel Recommendations and therapies for nonmuscle invasive and recurrent blad­der cancer.Chapters 11-22 encompass clinical management of bladder cancer. Starting from the low-grade bladder cancer, Chap. 11 by Dr. William Oosterlink focuses on histology, risk factors, and diagnosis and detection of low-grade tumors in the blad­der and the upper tract, whereas Chap. 12 by Allaparthi and Balaji covers the clini­cal management of low-grade tumors.

Intravesical chemotherapy or immunotherapy (Bacillus Calmette-Guerin [BCG]) are key adjuvant therapies for the control of high-grade nonmuscle invasive bladder cancer. In Chap. 13, Drs. Adiyat, Katkoori, and Soloway is a review of indications and practical aspects of administration of intravesical chemotherapy, properties, efficacy, and side effects of various intravesical agents, and newer methods improv­ing the efficacy of the intravesical drugs. Although, many reviews have been writ­ten on intravesical BCG therapy, the review by Drs. Bishay, Park, and Hemstreet is unique because of the depth of discussion on the mechanism of action of BCG in animal versus cell culture models, and the involvement of the immune system and inflammatory cytokines/chemokines in mediating response to BCG.

Actos and Bladder Cancer : Your physicians should be confident enough in their recommendations that they are neither intimidated nor angered by your desire to seek a second opinion. If you experience either of these reactions, then you can be confident in your decision to seek a second opinion. Generally, your physicians will hope that you return to them to discuss the second opinion afterward, espe­cially regarding anything that is divergent from their own recommendations. Most patients return to their original caregiver after getting a second opinion, although you are never obligated to do so.

Most patients will not need to stay in the hospital overnight after a TURBT. The final decision on stay­ing in the hospital or returning home is made based on the amount of resection necessary and the amount of blood in the urine after the procedure. These two fac­tors will also determine whether a catheter needs to be left in place after the procedure, usually for a few days. TURBT is generally regarded as a low-risk procedure. It is typically performed as a day surgery procedure, meaning that you will not need to stay in the hospital overnight. As with any surgery that requires anesthe­sia, a small risk is associated with the anesthesia. This risk is higher if you have other conditions such as asthma, chronic obstructive pulmonary disease, or car­diovascular disease, but is still generally very low risk.

Perioperative chemotherapy refers to the practice of instilling one of the bladder chemotherapies immedi­ately after TURBT, usually while you are still in the operating room or the recovery room. Traditionally, these intravesical therapies have been given after the bladder has healed, 2 to 3 weeks after surgery. Several studies in the last 10 years have shown benefits to giv­ing a single dose of chemotherapy at the time of TURBT. The benefit presumably derives from killing any cancer cells that are still swirling around in the bladder after TURBT, thus preventing them from implanting in the bladder.

PDT is a new treatment that is still evolving. It is cur­rently given only to patients with recurrent tumors who have failed BCG treatment. Newer sensitizing agents have improved its efficacy. In one study, 84% of patients with BCG-resistant papillary tumor had a complete response, and 75% of patients with carci­noma in situ had a complete response at the 3-month follow-up. At a median follow-up of 4 years, 31 of 34 patients who had responded were still tumor-free. PDT appears to be useful in patients with superficial bladder cancer but has not yet been widely adopted.

Superficial bladder cancer is a recurrent and potentially progressive disease. Most studies have shown that patients with a higher stage and/or grade (Questions 29 and 30) have recurrences more frequently than do patients with a lower stage or grade. Approximately half of the lowest stage and grade tumors (Ta, Grade I/II) will recur, most of them in the first 3 months after treat­ment. Carcinoma in situ recurs in up to 70% of patients.

The treatment of choice currently for carcinoma in situ is intravesical therapy with BCG (Question 35). Carci­noma in situ in most cases is not adequately treated by resection alone because it tends to be located diffusely throughout the bladder. Sixty to 70% of patients with carcinoma in situ will respond to a standard course of BCG. Although encouraging, this obviously means that 30% to 40% of patients will fail a standard course, and thus most experts advise further therapy. Some advocate two courses of BCG, whereas others prefer maintenance BCG for 3 years; urine is sent for cytology every 3 to 12 months. Also, periodic cystoscopy will need to be performed in the urologist’s office, and any suspicious lesions will need to be biopsied and exam­ined under the microscope by a pathologist.

Actos and Bladder Cancer : A catheter is a plastic or rubber tube which is placed through the urethra into the bladder. It is kept in place by a fluid filled balloon, at the end of the catheter, which is inflated in the bladder. The tube allows for drainage of urine which may be mixed with blood after a TURBT. When small tumors are removed, a catheter is not usually required unless there is a concern that you may have difficulty urinating after the procedure because of an enlarged prostate, weak bladder or swelling of the urethra after instrumentation. After large tumors are resected, a catheter is often required. It serves the following purposes:

It allows one to monitor the amount of bleeding after surgery (although the urologist attempts to stop all bleeding, this is not always possible and bleeding may persist).

It provides for bladder irrigation if required. If much bleeding is present after surgery, it is important to avoid the possibility of blood clots forming and blocking the flow of urine. Irrigation can be done intermittently with a syringe or continuously via a 3 way catheter, which has a port for inflow and outflow of irrigant.

It keeps the bladder decompressed, which may be important if the resection was deep and bladder integrity is in question. The bladder may have been thinned markedly in the area of resection or biopsies. Decompression provides for reduced risk of leakage through the wall of the thinned bladder.

HOW UNCOMFORTABLE IS THE CATHETER?

Most individuals complain of some discomfort from their catheter. The most common complaint is a feeling of pressure in the bladder, often thought to be secondary to stimulating the bladder and resulting in a “bladder spasm”. This sensation can often be reduced markedly with medication to relax the bladder. Sometimes pain medication is also required. The catheter may also cause irritation at the opening of the urethra, which can be reduced by being sure the catheter is kept clean at this site via gently cleansing and possibly applying an antibiotic ointment to the urethral opening.

Information from other sources on Actos and Bladder Cancer

If it was placed for bleeding, generally when the bleeding slows or stops over a day or two, the catheter will be removed. If it is in for a compromised bladder wall, it may need to remain for a week or more. When the catheter is removed, the urologist simply empties the balloon that holds it in place, and then gently pulls out the catheter. There is minimal discomfort during removal and generally a smile follows once it is out.

WHAT IS CANCER?

Cancer is defined as a group of diseases characterized by uncontrolled growth and spread of abnormal cells. Cells are the small building blocks of our body and most other living organisms. If the spread of these abnormal cells is not controlled, it can result in organ dysfunction and death. There are several cancers, each affecting various portions of the body. Cancer can be caused by external factors like cigarette smoking, exposure to certain chemicals, radiation, or infectious organisms. Internal factors that can lead to cancer include inherited mutations, hormones, and conditions

affecting your immune system. Mutations are permanent changes in your hereditary material, and hormones are products of certain cells in our body that influence the function of other cells.

More information on Actos and Bladder Cancer

Although scientists have been able to uncover the cause of some cancers, there is still a great deal to be learned. One may go through his or her entire life without exposure to any of the previously mentioned factors and develop cancer. Men have a higher risk of developing cancer, with a slightly less than i in 2 lifetime risk in the United States compared with 1 in 3 for women. Although cancer is more common than you may think, doctors have figured out new ways to diagnose and treat cancer. By no means is cancer a death sentence; it can be managed and a lot of people diagnosed go on to live healthy and productive lives for many years after treatment.

Epidemiology is essentially the study of factors affecting the health and illness of populations. Before moving on with our discussion about bladder cancer, it’s important to gain perspective on how many people live with bladder cancer.

There are over 1 million people throughout the world living with bladder cancer. Bladder cancer is the seventh or ninth most common cancer, depending on where you live. Most individuals with bladder cancer live in industrialized countries and geographical areas where infection with the parasite Schistosoma haematobium is common. In the United States bladder cancer is the fourth most common cancer in men and the ninth most frequently diagnosed cancer in women. The male-to-female ratio is 3 to 1. Two- thirds of cases are diagnosed in people over age So, but it

can occur very early in life. Two times as many whites will be diagnosed with bladder cancer compared with African Americans. The reasons for this are unclear.

Actos and Bladder Cancer :

WHAT CAUSES BLADDER CANCER?

Ludwig Rehn, a German surgeon during the 19th century, is credited with the first explanation of one of the root causes of bladder cancer. He established a link between exposure to chemicals used in the production of colored textiles and the development of bladder cancer in factory workers. Although his discovery was not initially accepted, bladder cancer was soon recognized as an occupational cancer in factory workers. This may help explain the higher incidence of bladder cancer in industrialized nations.

Exposure to a number of chemicals has been associated with the development of bladder cancer. These include aniline dyes and other members of the aromatic amine family. People who work in occupations where exposure to these chemicals is common include textile workers, dye workers, rubber workers, painters, and even hairdressers. Please see Table 1-1 for a list of occupations associated with an increased risk of developing bladder cancer.

Information from other sources on Actos and Bladder Cancer

Smoking is the most common cause of bladder cancer today. It increases your risk of developing bladder cancer 2- to 4-fold compared with people who don’t smoke. The risk of bladder cancer increases with the frequency and duration of smoking. For example, someone who smokes one pack a day for 20 years has a higher risk of bladder cancer than someone who smokes a few cigarettes on weekends. When you stop smoking you can slowly decrease the risk of bladder cancer, over the course of 20-30 years. If you currently smoke, it would be best to stop smoking
