Bladder Cancer

In less than a decade, docetaxel (Taxotere) has progressed from initial studies in anthracycline-refractory metastatic breast cancer to several large, phase III randomized trials evaluating its efficacy as adjuvant, neoadjuvant, and first-line therapy for metastatic breast cancer, non-small-cell lung cancer (NSCLC), and ovarian cancer. In other tumor types, including prostate, head and neck, gastric, and bladder cancer, ongoing phase III trials are comparing docetaxel-containing regimens to previously established regimens. For the seven tumor types reviewed in this supplement, phase III study information for docetaxel or docetaxel-based combinations are presented. Impressive results have been consistently demonstrated in the trials reported to date.

The multistep process of carcinogenesis, which can take many years, provides many opportunities for intervention to inhibit disease progression. Effective chemoprevention agents may reduce the risk of cancer by inhibiting the initiation stage of carcinoma through induction of apoptosis or DNA repair in cells harboring mutations, or they may act to prevent promotion of tumor growth. Similarly, chemoprevention may entail blocking cancer progression to an invasive phenotype.

Among the most exciting new anticancer products presented at the 2001 ASCO meeting were new drugs that block the epidermal growth factor receptor (EGFR). About 30% to 90% of carcinomas express high levels of EGFR. These include, among others, head and neck cancer, lung cancer, pancreatic cancer, colon cancer, breast cancer, ovarian cancer, and bladder cancer.

Fenretinide (N-4-hydroxyphenyl-retinamide, or 4-HPR) is a semisynthetic retinoid that was initially developed as a low-dose chemopreventative agent.[1-3] Unlike other naturally occurring retinoids such as all-trans, 13-cis, and 9-cis retinoic acids, fenretinide does not induce systemic catabolism that interferes with the maintenance of effective plasma levels during long-term use. This characteristic, combined with the agent’s low toxicity and its ability to block aspects of carcinogenesis, provided the rationale for the development of fenretinide in lower doses as a chemoprevention agent for breast, prostate, and bladder cancer.

Conventional histopathologic evaluation of bladder cancer, encompassing tumor grade and stage, is inadequate to accurately predict the behavior of most bladder tumors. Intense research efforts are under way to identify and

ANAHEIM, California-A phase III Intergroup trial has provided strong evidence that neoadjuvant MVAC-methotrexate, vinblastine, doxorubicin (Adriamycin), cisplatin (Platinol)-provides a survival benefit in patients with locally advanced bladder cancer, David Crawford, MD, said at the American Urological Association (AUA) annual meeting (abstract 1069).

ANAHEIM, California-In patients with superficial bladder cancer, it is possible to optimize treatment with mitomycin (Mutamycin) by enhancing the drug concentration in urine, according to the results of a multicenter study presented at the American Urological Association annual meeting (abstract 776).

In a recent issue of ONCOLOGY (15:85-88, 2001), Drs. Edgar C. Baselli and Richard E. Greenberg presented a brief

Drs. Vaughn and Malkowicz have provided us with a succinct, thorough, evidence-based overview of the current role of chemotherapy in advanced bladder cancer. Their discussion highlights the veritable explosion of new chemotherapy agents

Drs. Vaughn and Malkowicz provide a fairly extensive and balanced review of chemotherapy for metastatic bladder cancer. They highlight the results obtained with some of the most commonly employed regimens that have been evaluated

Invasive bladder cancer is a chemotherapy-sensitive neoplasm. Historically, the development of cisplatin (Platinol)-based chemotherapy regimens has represented an important advance for patients with metastatic

BOSTON-A combination of transurethral resection (TUR) and radiochemotherapy with cisplatin (Platinol) and fluorouracil (5-FU) produced the most promising results in a German study of bladder-sparing protocols for patients with invasive bladder cancer.

CARPINTERIA, Calif-A newly available fluorescent-based immunocytologic test to detect superficial bladder cancer, ImmunoCyt, used in conjunction with urinary cytology, will likely reduce the need for periodic cystoscopies in patients with transitional cell bladder cancer and enhance the early detection of recurrent disease.

Transurethral resection remains the standard for first-line treatment of transitional cell carcinoma of the bladder. This technique clearly defines the pathologic grade and is essential in determining the clinical stage of

The fastest growing segment of the US population is the group over the age of 65 years. In the next 30 years, this group will comprise over 20% of the population. Because 60% of all cancers occur in this age group, there will be an expected rise in the total cancer burden.

Researchers who conducted a large, randomized clinical trial across Europe, Great Britain, and Canada found that in order to improve safety and reduce toxicity, advanced bladder cancer patients can be treated with a combination of gemcitabine (Gemzar) and cisplatin (Platinol). This combination (known as GC) did not extend survival, but it was much less toxic than the currently used combination, MVAC (methotrexate, vinblastine, doxorubicin [Adriamycin], and cisplatin).

COPENHAGEN-For patients with locally advanced or metastatic bladder cancer (transitional cell carcinoma of the urothelium), the combination of gemcitabine (Gemzar) and cisplatin (Platinol) may offer a less toxic regimen, according to a presentation at the ASCO meeting.

Despite being one of the more common genitourinary neo plasms, superficial transitional cell carcinoma involving the urinary bladder can be a confusing entity for the treating physician. This confusion stems, in large part, from the binary classification

Baselli and Greenberg have presented a comprehensive overview of intravesical strategies for the management of superficial urothelial malignancies of the bladder, both past and present. A number of points made in the article deserve further
