Actos Warning : Tobacco smoking and occupational exposure have been the two major factors related to BC risk; however, not all smokers develop BC and not all cases of BC occurred in smokers or patients with chemical exposure. It has been proposed that there could be factors other than environmental that could affect the incidence on urothelial tumors. In fact, as for many other cancers, molecular researchers are trying to establish genetic alterations linked to carcinogenesis that could justify genetic predisposition.An important research has been conducted in patients with BC in relation to smoking and chemical exposure , trying to identify those patients with higher sus­ceptibility of being affected by environmental carcinogens. Aromatic amines were established carcinogens for urothelium.

They could be inactivated by acetylation pathway, and it has been postulated that those patients with slow acetylation capability were more susceptible to BC than those that are rapid acetylators. NAT-1 and NAT-2 are N-acetyltransferase genes located on the short arm of human chromosome 8 and they are involved in amines inactivation. Reduction in NAT-2 activity has been suggested as mechanism for BC predisposition among patients exposed to environmental carcinogens such as aromatic amines.A number of SNPs have been reported in NAT-2 coding exon, as well as over 35 NAT-2 haplotypes have been identified (Hein 2006). Several of these haplotypes corresponded to NAT-2 slow acetylator phenotype and NAT-2 slow acetylation genotype has been related to higher risk of BC.

The Spanish Bladder Cancer Study is a hospital-based case-control study on BC conducted in five different areas in Spain that included 1150 cases and 1149 controls. They evaluated in this great population the association of several polymorphisms in NAT and GST genes with BC risk and their interaction with cigarette smoking. In addition, they reported a metaanalysis of 29 studies of NAT-2 and BC including 5096 cases and 6519 controls. They demonstrated that NAT-2 slow acetylators had a 40% increase in BC risk compared to rapid/intermediate acetylators with an OR of 1.4 (95% CI, 1.2-1.7). They could also demonstrate a significant multiplication interaction between NAT-2 slow acetylation genotype and cigarette smoking, that is, NAT-2 slow acetylators were especially susceptible to the adverse effects of ciga­rette smoking on BC risk. On the other hand, the metaanalysis performed corrobo­rated their own data, being the summary on relative risk for NAT-2 slow acetylators compared to rapid/intermediate acetylators of 1.4 (Garcia-Closas et al. 2005).Other SNPs in different genes have been studied. Nucleotide excision repair (NER) pathway is a complex mechanism for repairing DNA damage and subse­quently for preventing carcinogenesis. NER pathway included several genes, and different SNPs on those genes have been related to an increase in BC risk. Twenty- two SNPs on seven NER genes were evaluated in 1150 cases and 1149 controls included in The Spanish Bladder Cancer Study. Four of these 22 SNPs in NER genes could be significantly related to a small increase in BC risk and interestingly it could be demonstrated as a stronger association between BC and polymorphism in ERCC2 gene (ERCC2 R156R) for never-smokers compared with ever-smokers (Garcia-Closas et al. 2006).

Other study including 696 patients with BC and 629 controls evaluated the asso­ciation with BC risk of a comprehensive panel of 44 SNPs in genes of NER path­way and genes involved in cell cycle control. They concluded that patients with higher numbers of variants in NER genes rather than single polymorphism are at increased risk for BC (Wu et al. 2006).

Actos Warning : Much attention has been paid to the influence of diet on cancer risk and treatment. Thus far, some scientists have suggested that vegetables, fresh fruits, and some fermented milk products appear to decrease one’s risk of developing bladder cancer. A few foods thought to increase the risk of developing bladder cancer are foods rich in animal fat, diose containing a lot of cholesterol, fried foods, and pro­cessed meat with various additives. We are not sure of the exact influence of diet on bladder cancer at this point in time. Scientists around the world are working on uncover­ing potential links between diet and bladder cancer.

ARE THERE VARIOUS TYPES OF BLADDER CANCER?

As with other cancers that affect different body parts, there are multiple types of bladder cancer. To better understand them, let’s separate bladder cancer into two different groups: primary tumors that originate in the bladder and secondary tumors that spread to the bladder from other places.

More information on Actos Warning

Primary bladder cancers form within the bladder. Over 90 percent of primary bladder cancers in the United States are of the urothelial or transitional subtype. These form along the inner lining of the bladder. The second most common type of primary bladder cancer in the United States is squa­mous cell carcinoma, making up approximately 5 percent of all cancers diagnosed. These are often diagnosed in indi­viduals whose bladder has been chronically irritated by an infection, stones, or an indwelling catheter. The third most common subtype of bladder cancer in the United States is adenocarcinoma, accounting for approximately 2 percent of all diagnosed cases. These typically form near the dome of the bladder. There are other types of primary bladder cancer, but these are very rare. If necessary, your urologist will speak to you about these rare types.

Information from other sources on Actos Warning

Secondary cancers form somewhere else in the body and spread to the bladder. Other tumors can get to the blad­der by using the bloodstream, your lymphatic system, or directly from an organ close to the bladder. Other cancers that spread to the bladder, in order of decreasing frequency, are melanoma, colon cancer, prostate cancer, lung cancer, and breast cancer.

Now that we’ve discussed some of the basics concerning bladder cancer, let’s examine how you should go about choosing a medical team to treat your cancer.

HOW TO SELECT YOUR ONCOLOGY TEAM AND BLADDER CANCER CENTER

You want your team to be knowledgeable and experienced in the care of patients with bladder cancer. Don’t rely on self-promoting advertisements on television as your way to select a facility and doctor. While you may seek out a com­prehensive cancer center (look for one accredited by Amer­ican College of Surgeons or National Cancer Institute), the important thing is that you select a facility that has bladder cancer specialists. These include urologists that specialize in cancer surgeries (not general urologists or surgeons who rarely perform cancer-related surgery), medical oncologists who specialize in bladder cancer, radiation oncologists, urologic pathologists, radiologists, genetics counselors, oncology nurses, and psychosocial support staff for cancer patients. It’s a highly specialized group. Your doctors and their staffs can be some of your best resources.

WHAT IS A BIOPSY?

A biopsy is a small piece of tissue obtained during cystos­copy when a urologist looks inside of your bladder. This tissue sample is then sent to the laboratory and looked at under a microscope by a pathologist. Although there are standards that all pathologists follow, there can be small differences that can be seen by a trained eye. This is why it’s important to obtain actual slides and not just the report.

In addition to biopsies, pathologists often look at urine specimens or bladder washings for the presence of abnor­mal cells. It’s important to bring this report to your first appointment as well.

RADIOLOGICAL STUDIES

Before youx referral to a bladder cancer specialist, your primary care provider or urologist may order one of a few radiology exams to help evaluate the extent of cancer. We’ll briefly discuss those tests commonly ordered during the workup of someone with bladder cancer. These tests help determine someone’s cancer stage. Again, it is very impor­tant to obtain copies of your images (the actual films or CDs) along with reports.

An ultrasound is a noninvasive test used to evaluate the kidneys and bladder. Ultrasounds are painless and don’t have any associated side effects. Ultrasounds are per­formed by either a radiologist or radiology technician and take approximately 30 minutes to complete. An ultrasound allows doctors to image your kidneys to determine wheth­er or not they are normal in size. An ultrasound can also determine if one of your lddneys is not draining properly, which can occur with bladder cancer. Although images of your bladder can be obtained, an ultrasound cannot rule out evidence of cancer. Ultrasound was a primary test used in the past to evaluate patients with bladder cancer; how­ever, we now have better tests that allow us to image your entire urinary tract in greater detail. Ultrasound pros in­clude its noninvasiveness and lack of radiation, whereas its cons remain its lack of fine details and the fact that some very small tumors can be missed.
