BACKGROUND With the development of stage-specific treatments for pancreatic cancer, controversies exist concerning optimal clinical and pathologic staging. The most recent edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual 6(th) Edition included some notable modifications. In anticipation of the 7(th) edition's publication, the(More)
BACKGROUND Evidence exists to suggest a pattern of increasing early diagnosis of renal cell carcinoma (RCC). The aim of the study was to analyze patterns of disease presentation and outcome of RCC by AJCC stage using data from the National Cancer Data Base (NCDB) over a 12-year period. METHODS The NCDB was queried for adults diagnosed between 1993 and(More)
PURPOSE Studies of perioperative chemotherapy for muscle invasive bladder cancer have shown a survival benefit with combined modality therapy. We reviewed chemotherapy use in patients with stage III transitional cell carcinoma of the bladder from 1998 to 2003 to evaluate perioperative chemotherapy treatment patterns. MATERIALS AND METHODS The National(More)
PURPOSE The proportion of renal cell carcinoma cases diagnosed at stage I is known to be increasing significantly. We characterized stage I tumors further in terms of tumor size at diagnosis using a large national cancer registry. MATERIALS AND METHODS The National Cancer Data Base captures approximately 75% of all newly diagnosed cancer cases in the(More)
On the basis of the National Cancer Data Base (NCDB), we describe the disease characteristics and use of conventional prognostic parameters in a hospital-based cohort of pathologically confirmed renal cell carcinomas (RCCs). Between 1993 and 1998, the NCDB obtained 149 424 cases of kidney (and renal pelvis) cancers from registries all over the United(More)
BACKGROUND Previous investigators have detected shifts to lower stages at diagnosis for renal cell carcinoma and prostate cancer. The authors investigated whether a similar pattern is seen for urothelial carcinomas of the bladder, ureter, and renal pelvis and sought to identify changes in cancer grade and survival trends from 1993 to 2005. METHODS The(More)
BACKGROUND A recent revision of the American Joint Committee on Cancer (AJCC) staging for gallbladder cancer (6th Edition) involved some major changes. Most notably, T2N0M0 tumors were moved from stage II to stage IB; T3N1M0 disease was moved from stage III to stage IIB; and T4NxM0 (x = any) tumors were moved from stage IVA to stage III. METHODS In order(More)
PURPOSE We analyzed patterns of disease presentation and outcome of renal cell carcinomas by gender using data from the National Cancer Database during a 10-year period. We hypothesized that women presented with lower stage disease and had increased survival than men due to increased imaging. MATERIALS AND METHODS The National Cancer Database is a(More)
PURPOSE The commencement of quality-improvement initiatives such as Pay for Performance and the Physician Consortium for Performance Improvement has underscored calls to evaluate the quality of cancer care on a patient level for nationally representative samples. METHODS We sampled early-stage prostate cancer cases diagnosed in 2000 through 2001 from the(More)
BACKGROUND Variations in patterns of care and treatment outcomes suggest differences in the quality of care for men treated for localized prostate cancer. OBJECTIVE We sought to compare adherence with quality indicators for prostate cancer care among men treated with radical prostatectomy or external beam radiation therapy.
