ABSTRACT: Although only 32,000 new cases of adenocarcinoma of the pancreas occur in the United States each year, it is the fourth leading cause of cancer deaths in this country. The overall five-year survival rate is 4 percent, and localized, resectable disease has only a 17 percent survival rate. Risk factors include smoking, certain familial cancer syndromes, and familial chronic pancreatitis. The link between risk of pancreatic cancer and other factors (e.g., diabetes, obesity) is less clear. Most patients present with obstructive jaundice caused by compression of the bile duct in the head of the pancreas. Epigastric or back pain, vague abdominal symptoms, and weight loss also are characteristic of pancreatic cancer. More than one half of cases have distant metastasis at diagnosis. Computed tomography is the most useful diagnostic and staging tool. Ultrasonography, magnetic resonance imaging, and endoscopic retrograde cholangiopancreatography may provide additional information. The majority of tumors are not surgically resectable because of metastasis and invasion of the major vessels posterior to the pancreas. Resectable tumors are treated with the Whipple procedure or the pylorus-preserving Whipple procedure. Adjuvant fluorouracil-based chemotherapy may prolong survival. For nonresectable tumors, chemotherapy with gemcitabine prolongs survival. Other agents are being studied. Radiation combined with chemotherapy has slowed progression in locally advanced cancers. Throughout the illness and during end-of-life care, patients need comprehensive symptom control.
NIH Statement on Adjuvant Therapy for Breast Cancer - Practice Guidelines
ABSTRACT: Bladder cancer is the sixth most prevalent malignancy in the United States. The most common type of bladder cancer is urothelial (transitional cell) carcinoma, and cystoscopy remains the mainstay of diagnosis and surveillance. Fluorescence cystoscopy offers improvement in the detection of flat neoplastic lesions, such as carcinoma in situ. Non-muscle-invasive bladder cancer is typically managed with transurethral resection and perioperative intravesical chemotherapy. Intravesical bacille Calmette-GuÃ©rin therapy is preferred over mitomycin for those at high risk of disease progression. For muscle-invasive disease, standard management is radical cystectomy. In these patients, neoadjuvant chemotherapy or postoperative adjuvant chemotherapy should be considered based on pathologic risks, such as positive lymph nodes or pathologic T stage. Multidrug systemic chemotherapy involving cisplatin is commonly used. No major organization recommends screening for bladder cancer.
Breast Cancer in Older Women - Article
ABSTRACT: The American Geriatric Society currently recommends screening mammography for women up to 85 years of age whose life expectancy is three years or longer. The value of clinical breast examinations in older women needs further study. Total mastectomy and partial mastectomy with postoperative radiation therapy yield similar results in localized breast cancer. Postoperative irradiation may be avoided in women with small tumors (2.5 cm or less in diameter) who have undergone quadrantectomy. Lymph node dissection is important for tumor staging but significantly increases the risks and morbidity of surgery. Lymph node mapping may obviate the need for lymphadenectomy in many older women. Adjuvant hormonal therapy for at least two years appears to be beneficial in all women with hormone-receptor-rich tumors. Adjuvant chemotherapy is indicated in women with lymph node involvement or high-risk tumors with no lymph node involvement. Unless life-threatening metastases are present, hormonal therapy is the first approach to metastatic cancer. Chemotherapy is indicated if endocrine therapy is unsuccessful or life-threatening metastases are present. Most chemotherapy regimens appear to be well tolerated, even by women over 70 years of age. Special treatment should be employed for metastases to tumor sanctuaries (i.e., brain, eyes), the long bones, the spine and the chest wall.
