Poorly controlled cancer pain is a significant public health problem throughout the world. There are many barriers that lead to undertreatment of cancer pain. One important barrier is inadequate measurement and assessment of pain. To address this problem, the Pain Research Group of the WHO Collaborating Centre for Symptom Evaluation in Cancer Care has developed the Brief Pain Inventory (BPI), a pain assessment tool for use with cancer patients. The BPI measures both the intensity of pain (sensory dimension) and interference of pain in the patient's life (reactive dimension). It also queries the patient about pain relief, pain quality, and patient perception of the cause of pain. This paper describes the development of the Brief Pain Inventory and the various applications to which the BPI is suited. The BPI is a powerful tool and, having demonstrated both reliability and validity across cultures and languages, is being adopted in many countries for clinical pain assessment, epidemiological studies, and in studies of the effectiveness of pain treatment.

Pain assessment: Global use of the Brief Pain Inventory.

Patients with ovarian cancer usually present with advanced disease, and the disease is generally managed with surgical resection followed by platinum-based chemotherapy. Recent chemotherapeutic advances have led to improved survival, and a better understanding of genetic risk factors has permitted a tailored approach to preventive strategies, such as bilateral salpingo-oophorectomy in selected women. This review describes the clinical features of ovarian cancer and recent advances in postoperative management.

This article highlights disparities in cancer incidence, mortality, and survival in relation to race/ethnicity, and census data on poverty in the county or census tract of residence. The incidence and survival data derive from the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) Program; mortality data are from the National Center for Health Statistics (NCHS); data on the prevalence of major cancer risk factors and cancer screening are from the National Health Interview Survey (NHIS) conducted by NCHS. For all cancer sites combined, residents of poorer counties (those with greater than or equal to 20% of the population below the poverty line) have 13% higher death rates from cancer in men and 3% higher rates in women compared with more affluent counties (less than 10% below the poverty line). Differences in cancer survival account for part of this disparity. Among both men and women, five-year survival for all cancers combined is 10 percentage points lower among persons who live in poorer than in more affluent census tracts. Even when census tract poverty rate is accounted for, however, African American, American Indian/Alaskan Native, and Asian/Pacific Islander men and African American and American Indian/Alaskan Native women have lower five-year survival than non-Hispanic Whites. More detailed analyses of selected cancers show large variations in cancer survival by race and ethnicity. Opportunities to reduce cancer disparities exist in prevention (reductions in tobacco use, physical inactivity, and obesity), early detection (mammography, colorectal screening, Pap tests), treatment, and palliative care.

Prevalence of pain in patients with cancer: a systematic review of the past 40 years

Background and Methods Pain is often inadequately treated in patients with cancer. A total of 1308 outpatients with metastatic cancer from 54 treatment locations affiliated with the Eastern Cooperative Oncology Group rated the severity of their pain during the preceding week, as well as the degree of pain-related functional impairment and the degree of relief provided by analgesic drugs. Their physicians attributed the pain to various factors, described its treatment, and estimated the impact of pain on the patients' ability to function. We assessed the adequacy of prescribed analgesic drugs using guidelines developed by the World Health Organization, studied the factors that influenced whether analgesia was adequate, and determined the effects of inadequate analgesia on the patients' perception of pain relief and functional status. Results Sixty-seven percent of the patients (871 of 1308) reported that they had had pain or had taken analgesic drugs daily during the week preceding the study, and 36 percen...

PURPOSEThis study was designed to assess the effectiveness of vinblastine, ifosfamide, and cisplatin (VeIP) as second-line therapy in patients with recurrent germ cell tumors with previous treatment with cisplatin plus etoposide, usually in combination with bleomycin.PATIENTS AND METHODSFrom July 1984 through December 1989, 135 patients with progressive, disseminated germ cell tumors after cisplatin-etoposide-based combination therapy induction chemotherapy were treated with VeIP. Patients who progressed within 3 weeks of previous cisplatin therapy were not eligible. Progression was documented by biopsy or increasing serum markers. No exclusion was made on the basis of metastatic site or performance status. The dosages were vinblastine 0.11 mg/kg/d (days 1 and 2), ifosfamide 1.2 gm/m2/d (days 1 through 5), and cisplatin 20 mg/m2/d (days 1 through 5), with courses repeated every 21 days for four cycles.RESULTSSixty-seven (49.6%) patients achieved a disease-free status after chemotherapy with or without sur...

Vinblastine plus ifosfamide plus cisplatin as initial salvage therapy in recurrent germ cell tumor.

PURPOSEThis study analyzed a large group of patients with testicular germ cell cancer in complete remission, who relapsed more than 2 years after completion of treatment.PATIENTS AND METHODSA review of all patients treated at Indiana University Medical Center from 1979 through 1992 for late relapse was conducted. Eighty-one patients were treated for late relapse of testicular cancer. Forty-seven patients relapsed more than 5 years after successful management of their initial disease.RESULTSAt initial diagnosis, 35 patients had clinical stage I, 18 stage II, and 28 stage III disease. Twenty-three of 35 stage I, all 18 stage II, and all 28 stage III patients were treated by chemotherapy before their late relapse. The median follow-up duration of patients post-management of late relapse was 4.8 years. Twenty-one patients (25.9%) are continuously disease-free. Nineteen of these 21 patients had surgical resection of carcinoma or teratoma as a component of their therapy. Of sixty-five patients treated for late ...

Late relapse of testicular cancer.

BACKGROUNDCyclophosphamide, which forms the nucleus for virtually all preparative regimens for autologous bone marrow transplantation (ABMT), is an alkylating agent of which cytotoxicity is not directly caused by the parent compound but by its biologically active metabolites. Its nonmyelosuppressive toxicity in the ABMT setting is cardiomyopathy. We attempted to determine any correlation between plasma levels of total cyclophosphamide and the subsequent development of cardiac dysfunction.PATIENTS AND METHODSAnalyses of plasma levels and the derivation of plasma concentration-time curves (area under the curve [AUC]) were performed in 19 women with metastatic breast carcinoma, who received a continuous 96-hour infusion of cyclophosphamide, thiotepa, and carboplatin (CTCb) with ABMT. The assay for total cyclophosphamide measures the inactive parent compound; reliable assays of the active metabolites of cyclophosphamide are not yet available.RESULTSSix of 19 women developed moderate, but transient, congestive...
