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: 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 : An intravenous pyelogram (IVP) is an X-ray study that shows the general outline of the kidneys and better detail of the collecting system than an ultra­sound. X-ray contrast is given to the patient intra­venously. The kidneys then filter and concentrate the contrast, creating an image on an X-ray taken a few minutes after the injection is given. A small tumor or stone inside the collecting system can be seen as a dark spot inside the collecting system. Historically, the IVP was a common test to evaluate upper tracts. However, due to the decreased cost of CT scans and the increased availability, it has largely been replaced by CT scanning.

CT scanners use X-rays to create a detailed image of the internal organs. The scanner takes many X-rays at once and uses a computer to combine all of the images into the one picture that you see. When getting a CT scan of the kidneys, the patient is usually scanned three times. The first scan is per­formed without contrast and will reveal any kidney stones. The second scan is performed with contrast, which helps to show tumors in the kidneys. The third scan is obtained a few minutes later, after the kidney has had time to process the contrast. The contrast fills the collecting system similar to the IVP but with greater detail. A CT scan is very good for seeing tumors in both the kidneys and the col­lecting system. In addition to the ability to see the kidneys and ureters better, the CT scan allows for visualization of the entire abdomen and lymph nodes, helping to identify metastases or unrelated diseases. Over the last several years, the cost of CT scans has come down, and the availability of scan­ners to patients has increased, making the CT scan the most common upper tract study. As with the IVP test, CT scans meant to examine the kidneys

Although ureteroscopy is not technically an “upper tract study,” it gives us the most definitive examina­tion. It is similar to cystoscopy but uses a smaller scope. In the operating room or well-equipped office, the ureteroscope is carefully passed into the ureter as it opens into the bladder. This allows the urologist to see the inside of the ureter. It is gently passed all of the way up the ureter into the kidney. Like cys­toscopy, there are both rigid and flexible uretero- scopes. The flexible scope allows doctors to see all or most of the deep corners of the collecting system within the kidney. Biopsies of any suspicious areas can be taken and sent to pathology for analysis. Although ureteroscopy provides the best view of the collecting system, it usually requires anesthesia, and there is some small risk of damage to the kidney or ureter; thus, it is usually reserved for those patients who have had an abnormal upper tract study.

Cysview (hexaminolevulinate hydrochloride, GE health­care) has recently been approved as an optical imaging agent for use in the cystoscopic detection of non-muscle invasive papillary bladder cancer among patients sus­pected or known to have lesion(s) on the basis of prior cystoscopy. When used in combination with blue light (fluorescence) cystoscopy (Karl Storz D-Light C Pho­todynamic Diagnostic [PPD] system) it identified at least 1 more noninvasive papillary bladder tumor than rou­tine cystoscopy in about one third of the patients with such tumors. It is also useful in detecting carcinoma in situ, identifying 28% more patients with carcinoma in situ than standard cystoscopy.

Urine cytology is commonly used to screen for bladder cancer in patients who have hematuria as well as to monitor for recurrences in patients who are being treated for bladder cancer. Overall, urine cytology is able to detect 40% to 60% of bladder cancers, but the ability of cytology to detect a tumor varies depending on the grade, stage, and location of the tumor. In low-grade, low- stage tumors, cytology will detect only 25% to 40% of the tumors. It will perform better as the grade and stage of the tumor increase, with the best detection rate being for carcinoma in situ. Cytology detects approximately 90% of cases of carcinoma in situ.

Actos and Bladder Cancer : Ureteral injury may occur when a tumor covers the ureter in the bladder. The ureter may be obscured by a bladder tumor, and the urologist may inadvertently resect it along with the tumor. In general, cutting current to remove a bladder tumor does not usually lead to long lasting problems as compared to cauterization, which is more likely to cause permanent blockage or obstruction of the ureter. If the urologist is working in the area of the ureter, he should avoid cauterization as much as possible. He may ask the anesthetist to inject an intravenous coloring agent which will turn the urine blue

and allow visualization of the ureter. If he knows a ureter may be in jeopardy, he may insert a stent (a small plastic tube that traverses the ureter) for several weeks to allow the ureter to heal in an open fashion.

Urethral injury is infrequent and is almost always in males. A stricture or narrowed area of the urethra may result from irritation or injury from the resectoscope pressing on the urethra. Individuals that develop strictures complain of difficulty urinating, experiencing a slow or split stream. Strictures are usually readily handled with a number of urologic procedures.

Bladder tumor “seeding” may occur during the procedure. As the tumors are resected, cancer cells are released into the irrigant which fills the bladder. These cells may implant in other areas of the bladder traumatized during the procedure. It should be understood that the bladder is generally filled with urine, and tumor cells can naturally implant at other locations even without surgery. Implantation can be lessened during surgery by avoiding injury to other bladder areas and by the use of adjuvant intravesical chemotherapy. There have been numerous studies over the past decade showing a number of chemotherapy agents can be effective in decreasing initial tumor recurrence, possibly by preventing seeding. Reduction in recurrence may however be short lived. Previously, it was common practice to obtain multiple random bladder biopsies at the time of initial tumor resection. This was recommended to rule out the possibility of hidden CIS. Understanding these biopsy sites may increase the possibilities of tumor recurrence by tumor seeding, biopsies are now often limited to areas adjacent to the tumors removed and suspicious appearing areas only. CIS can be ruled out by using cytology, or by obtaining biopsies during future cystoscopy after the tumor has already been removed. When dealing with low grade tumors, random biopsies of the bladder will rarely show cancer.^[1]

After your procedure, depending on the level of anesthesia and the extent of surgery, you will be brought either to the recovery room or back to the area where you were first prepared for your procedure. You will be released to home only when you have fully recovered from you anesthetic and are doing well.

Actos and Bladder Cancer : The recurrence rate for superficial bladder cancer can be as high as 60-90%. Recurrences can cause bleeding and other difficulties and are best handled sooner rather than later. In addition, depending on the initial tumor grade and stage, progression to a more serious form of bladder cancer is an ongoing concern. Surveillance cystoscopy is therefore recommended.

More information on Actos and Bladder Cancer

Cystoscopy is still the best means to check for recurrent disease. It is however, an invasive procedure and should be accomplished only as often as required. For solitary, low grade, non invasive disease, follow up cystoscopy can be accomplished with the flexible cystoscope if available. If negative at three months, further cystoscopic exams can be done yearly and eventually lengthened even further. For those with multiple tumors, large tumors, high grade tumors or those who also have CIS, frequent cystoscopies, initially every three months are called for. As long as there are no recurrences, the time between cystoscopies can be lengthened. Cytology can also be utilized to reduce the number of cystoscopies. If recurrence or progression does occur, heightened scrutiny is again called for.

BESIDES A BLADDER TUMOR, MY CT SCAN INDICATED MY KIDNEY IS SWOLLEN BECAUSE OF A BLOCKAGE OF MY URETER. DID THE BLADDER TUMOR CAUSE THIS BLOCKAGE AND DOES IT MEAN MY PROGNOSIS IS WORSE?

There are many medical conditions that may result in hydroureteronephrosis (swelling of the kidney and ureter), having nothing to do with bladder cancer. It is also true large bladder tumors may grow into the wall of the bladder and cause ureteral obstruction at the level of the bladder. When this is found, the prognosis is usually poor, as the tumors involved are usually high grade and deeply invasive. On occasion, a superficial low grade tumor may grow directly into the ureteral opening. In this situation, prognosis is not generally any worse, as the blockage has not occurred from an invasive tumor.

Actos and Bladder Cancer : The urinary system (Figure i-i) is very important and has a pretty tough job to do in everyone’s body. It filters your blood and produces waste products in the form of urine. More importantly, it allows you to store urine until it is convenient to urinate. Just think, if we couldn’t store urine, then we would constantly leak waste products. This would make life very difficult and get in the way of things we do during the course of a normal day. The human urinary system is made up of the kidneys, ureters, bladder, and urethra. Men have a prostate gland in addition to the previously mentioned components.

More information on Actos and Bladder Cancer

Your kidneys are two bean-shaped organs that reside in the rear of your abdomen, just under the diaphragm on the left and below the liver on your right side. The kidneys filter blood and produce urine. They are extremely important to life and work extremely hard to filter waste from your bloodstream. Just imagine, the kidneys filter approximately 20 percent of your blood each minute. Although most people have two kidneys, some individuals have one and do just fine. The kidneys function independently, and when one is not working as well, the other compensates and filters more blood. In addition to filtering blood and producing urine, your kidneys help to regulate your blood pressure. They produce special hormones and control the salt and water balance in your body. Normally, the kidneys do not release blood cells into urine. This is why it’s important to be evaluated by a doctor if you have blood in your urine.

URETERS

After urine is formed by the kidneys, special nerves and muscles in the renal pelvis propel urine downward into the ureters. The ureters are small tubes, very much like the renal pelvis, that allow passage of urine from die kidneys down to the bladder. They function as drainage pipes for the kidney. The ureters have nerves and layers of muscle that propel urine to the bladder. There is so much that your body does that you may not realize. Like the renal pelvis, the ureters are also lined with transitional cells serving as a continuation of die uxothelium.

Actos and Bladder Cancer :

BLADDER

The ureters connect to the bladder, which is a muscular, balloon-lilce structure in the pelvis. The bladder functions as the storage unit of the urinary system. It can hold upward of 500-600 mL (2 cups) of urine. Hie bladder is very thick and elastic with multiple layers .

An inner layer made up of transitional cells forming the urothelium; under this lies a thin layer (the lamina propria), with blood vessels supplying the bladder; and finally a thick muscular layer that contracts to empty your bladder. There is a layer of fat surrounding the muscular layer.

The bladder expands in relation to the amount of fluid inside of it Bladder contraction is under complex control by your central nervous system. When your bladder contracts during urination, urine passes though the urethra before leaving your body. The inner cells, closest to the bladder, are transitional cells, whereas the cells closest to the outside of the body are squamous cells resembling skin. Although the urethra has different lengths in men and women, it functions the same. In men, the urethra passes through the prostate gland near the bladder.

PROSTATE

The prostate, a walnut-sized organ that lies at the base of the bladder in men, plays a role in male fertility. Along with the seminal vesicles, the prostate gland produces fluid that helps sperm after ejaculation. Although the urethra passes through the prostate, the gland itself does not add much, if anything, to the volume of urine that reaches the bladder. As the urethra passes through the prostate, it is lined by transitional cells comprising the urothelium. Therefore, tilings that affect the urothelium can affect the prostate as well. This is very important when it comes to staging bladder cancer.

The urethra is a hollow tube lined with transitional cells at its beginning that connects the bladder to the outside world. The structure of the urethra is different in men and women. The urethra is short in women and is much longer in men due to the presence of the penis. The cells lining the

urethra change along its length. The inner cells, closest to the

Actos and Bladder Cancer12/20/2011: The neurovascular bundles which run adjacent and adherent to the prostate can be pushed aside as the bladder and prostate are removed. This is more technically difficult compared to the standard non-nerve sparing approach. Sparing the nerves is not always possible even with the best effort. If the individual has questionable erections prior to the surgery, a nerve sparing procedure rarely leads to preservation of erections and therefore is not warranted. Extensive bladder cancer may encroach on the prostate, making a nerve sparing procedure extremely difficult if not impossible.
