Cancer screening and risk-reducing behaviors of women seeking genetic cancer risk assessment for breast and ovarian cancers.

PURPOSE/OBJECTIVES: To examine breast and ovarian cancer screening and risk-reducing behaviors of women seeking genetic cancer risk assessment (GCRA). DESIGN: Descriptive, cross-sectional. SETTING: An insurance-based clinic that serves high-risk patients in a southern California cancer center. SAMPLE: 134 women with breast or ovarian cancer (affected group) and 80 women with a family history of breast or ovarian cancer (unaffected group). The mean age of the sample was 48 years (range = 21-86), 79% were Caucasian, 66% were married, 60% were college educated, and 78% had children. Most affected women had early-stage disease. Unaffected women had a family history of breast (86%) or ovarian (14%) cancer. METHODS: Mailed surveys assessed pre-GCRA health behaviors and health and family histories. MAIN RESEARCH VARIABLES: Breast cancer screening (mammograms, clinical breast examination [CBE], breast self-examination), ovarian cancer screening (CA-125, pelvic ultrasound), and breast and ovarian cancer risk-reducing strategies (tamoxifen, bilateral mastectomy, oral contraceptive pills, bilateral salpingo-oophorectomy). FINDINGS: Twenty-one percent of the women who should have been having a mammogram had not had an annual examination as recommended, and 30% of affected women had not had annual CBEs. Few women took tamoxifen or oral contraceptive pills or had a bilateral salpingo-oophorectomy or bilateral mastectomy for cancer risk reduction. Twelve percent likely had unnecessary ovarian cancer screening. About 35% used other means, including herbs and homeopathy, for cancer prevention. CONCLUSIONS: Nearly a third of the affected women had not had appropriate breast cancer screening. About 12% used unsubstantiated, potentially harmful cancer "prevention" measures (e.g., herbs). IMPLICATIONS FOR NURSING: Nurses should assess clients' personal and family breast and ovarian cancer histories and promote cancer screening and risk-reducing behaviors that are appropriate for age and risk level.

Beliefs and interest in cancer risk in an underserved Latino cohort.

OBJECTIVE: To measure beliefs about cancer causation, cancer screening behaviors, access to information about and resources for cancer screening, and interest in cancer genetics services in two underserved predominantly Latino communities. METHODS: An anonymous survey, in both English and Spanish, was distributed at the registration desk to all attendees of selected general medicine clinics in two underserved healthcare systems. RESULTS: There were a total of 312 respondents, representing 98% of eligible candidates. The reported data focus on 75.3% (n=235) of Latino respondents; mean age 43 years; 78% female; 72% less than high school education. Heredity was perceived as the most frequent cause of cancer, after smoking. Only 37% knew of free cancer screening programs. Over 85% expressed interest in obtaining information about personal cancer risk and motivation to participate in cancer genetics services. CONCLUSIONS: The results of this survey demonstrate an awareness of heredity as a potential cause of cancer. The observed high level of interest in cancer genetics services suggests the acceptability of cancer genetics services in this predominantly underserved Latino population. Furthermore, cancer genetics services would likely augment awareness and utilization of available cancer screening services in the community.

Perspectives on the impact of ovarian cancer: women's views of quality of life.

PURPOSE/OBJECTIVES: To describe quality-of-life (QOL) concerns particular to women with ovarian cancer and to examine whether subgroups of patients with ovarian cancer have significantly different QOL concerns. DESIGN: Mailed survey. SAMPLE: Readership of an ovarian cancer newsletter. METHODS: A total of 1,383 surveys were received in response to the survey's inclusion in the November 2002 issue of Conversations! The International Newsletter for Those Fighting Ovarian Cancer, a monthly newsletter circulated to 3,300 women with ovarian cancer (response rate = 42%). Women were asked to complete the 45-item City of Hope QOL Ovarian Cancer Tool (QOL-OVCA) and a short demographic questionnaire. MAIN RESEARCH VARIABLES: Patients' QOL-OVCA scores were compared across six independent variables, including disease status, age at diagnosis, stage at diagnosis, marital status, household income, and use of alternative therapy, controlling for survival time. FINDINGS: Ovarian cancer survivors reported significant QOL concerns across dimensions of physical, psychological, social, and spiritual well-being. CONCLUSIONS: Patients with ovarian cancer experience particular QOL concerns requiring support. Future research is needed to describe the needs of survivors in more diverse populations and to develop and test interventions that can address these QOL concerns. IMPLICATIONS FOR NURSING: Women with ovarian cancer experience QOL concerns common to other patients with cancer and some that are particular to ovarian cancer. Nurses should assess for and aggressively address these QOL concerns.

On the meaning of "drug seeking".

The term "drug seeking" is frequently used but poorly defined. By soliciting nurses' comments and suggestions, a survey was developed to identify behaviors that may cause nurses to refer to a patient as drug seeking, to identify what nurses think the term "drug seeking" means, to explore how nurses regard the use of the term "drug seeking" in health care, and to identify differences between general nurses, emergency nurses, and pain management nurses with regard to these items. Behaviors that would cause the majority of all three nurse groups to refer to a patient as drug seeking were as follows: going to different emergency departments to get opioids, telling inconsistent stories about pain or medical history, or asking for a refill because the prescription was lost or stolen. When the term "drug seeking" is used, all three groups of nurses agreed that it was very likely to mean the patient was addicted to opioids, the patient was abusing pain medicine, or the patient was manipulative. One-half or more for each nurse group said they used the term "drug seeking" in talking about patients, but less than 10% said they used it in charting. After completing the survey, approximately one half or more of nurses in each group were less inclined to use the term. The use of stigmatizing terms in clinical practice is addressed with suggestions for alternative approaches to patient behavior related to requesting opioids for pain relief.

Outcomes from intensive training in genetic cancer risk counseling for clinicians.

PURPOSE: Genetic cancer risk assessment is an emerging interdisciplinary practice that requires knowledge of genetics and oncology and specialized patient and family counseling skills. There is a growing need for cancer risk assessment practitioners, but most clinicians have inadequate cross-disciplinary training. An interdisciplinary course was developed to promote practitioner-level competency in cancer risk assessment to community-based clinicians. METHODS Participants were competitively selected from a pool of board-certified/eligible genetic counseling, masters-trained advanced practice nursing and physician applicants. Preference was given to clinicians with strong institutional backing practicing in underserved regions. The Continuing Medical Education/Continuing Education Unit-accredited course included didactic lectures, workshops, counseling practicum, and case conferences. Pre- and postcourse knowledge tests measured cancer genetics knowledge. Six month and one-year postcourse practice outcome surveys measured the impact of the program on professional self-efficacy and continued professional development. RESULTS/CONCLUSIONS: Forty clinicians completed the course (23 genetic counselors, 14 nurses, and three physicians). There was a significant overall increase of 22.6% in postcourse knowledge scores (P < 0.001). Thirty-five (88%) completed prescribed practice development activities. Of 29 respondents to 1-year postcourse survey, 76% reported increased professional self-efficacy; 66% reported increase in number of patients seen, and virtually all indicated interest in additional training. Outcomes demonstrate the value and efficacy of interdisciplinary training in genetic cancer risk assessment targeted to motivated community-based clinicians. Courses such as this can help address the need for competent cancer risk assessment services in communities outside the academic health center.

Elevated body temperature independently contributes to increased length of stay in neurologic intensive care unit patients.

OBJECTIVE: Elevated temperature results in worse outcome in experimental models of cerebral ischemia and brain trauma. In critically ill neurologic and neurosurgical patients, elevated body temperature is common and is associated with neurologic deterioration and poor outcome. We sought to determine whether, after controlling for age, severity of illness, and complications, elevated body temperature remained an important predictor of intensive care unit (ICU) and hospital length of stay, mortality rate, and hospital disposition in a large cohort of patients emergently admitted to a neurologic ICU. DESIGN: Prospectively collected data (demographics, diagnosis, Acute Physiology and Chronic Health Evaluation II score, Glasgow Coma Scale score, daily maximum temperature, complications, disposition) were retrospectively reviewed. SETTING: A 20-bed neurology/neurosurgery ICU in a tertiary care academic, level I trauma, referral center. SUBJECTS: From 6,759 admissions, those admitted after an elective procedure with length of stay < or = 1 day, those <18 yrs old, and those with incomplete data were excluded, leaving 4,295 patients for this analysis. First, a hierarchical multiple regression analysis was performed to determine whether elevated body temperature was an independent predictor of length of stay. Second, a path analysis was performed to define the relationships among elevated body temperature, complications, and length of stay. Finally, a matched, weighted sample was developed to quantify the difference in length of stay. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We measured ICU and hospital length of stay, mortality rate, and discharge disposition. The presence of elevated body temperature was associated with a dose-dependent longer ICU and hospital length of stay, higher mortality rate, and worse hospital disposition. The most important predictor of ICU length of stay was the number of complications (beta =.681) followed by elevated body temperature (beta =.143). In the matched, weighted population, the presence of elevated body temperature was associated with 3.2 additional ICU days and 4.3 additional hospital days. CONCLUSION: In a large cohort of neurologic ICU patients, after we controlled for severity of illness, diagnosis, age, and complications, elevated body temperature was independently associated with a longer ICU and hospital length of stay, higher mortality rate, and worse outcome.

Decision making in palliative surgery.

BACKGROUND: Palliative surgery for advanced cancer patients involves complex decision making. Surgeons with a cancer-focused practice were surveyed to determine the extent to which palliative surgery was currently practiced, to identify ethical dilemmas and barriers they faced in performing palliative surgery, and to evaluate their treatment choices in four different clinical scenarios. STUDY DESIGN: A 110-item survey was devised after extensive review of the palliative care and palliative surgery literature to evaluate current practices and attitudes regarding palliative surgery. Case vignettes were devised to evaluate dinical factors influencing surgeons' selection of treatment for symptomatic patients with advanced malignancy. RESULTS: Survey response rate was 24% (419 of 1,740). Respondents reported 74% of their surgery caseload as cancer related, and 21% of these as palliative. On a scale of 1 (uncommon problem) to 7 (common problem), surgeons reported that the most common ethical dilemmas in palliative surgery were providing patients with honest information without destroying hope (5.6 +/- 1.4) (mean +/- standard deviation), and preserving patient choice (5.0 +/- 1.7). Bound on error of the average frequency estimate for ethical dilemmas, based on response rate, was 0.08. On a scale of 1 (not a barrier) to 7 (a severe barrier), surgeons rated the most severe barriers to optimum use of palliative surgery as limitations of managed care (4.1 +/- 2.0) and referral to surgery by other specialists (3.9 +/- 1.8). Bound on error of the estimate for average severity of barriers, based on response rate, was 0.09. They rated the least severe barriers to palliative surgery as surgeon avoidance of dying patients (3.0 +/- 1.8) and surgery department reluctance to perform palliative surgery (2.6 +/- 1.6). Analysis of surgeons' treatment selection in case vignettes indicated that patient age, aggressiveness of tumor biology, local extent of disease, and severity of patient symptoms were all variables of influence for treatment selection in patients with advanced malignancies. CONCLUSIONS: Palliative surgery involves numerous ethical dilemmas, the most prominent being providing honest information to patients without destroying hope, and complex treatment decision making. We have identified variables of major influence to surgeons in the palliative treatment selection for patients with advanced, solid malignancies. Validation of these variables as meaningful will require future studies focusing on patient outcomes.

Health beliefs of women with and without breast cancer seeking genetic cancer risk assessment.

Genetic cancer risk assessment (GCRA) is increasingly being incorporated into clinical care. Planning supportive nursing care for women seeking GCRA requires knowledge of their health beliefs. We described and compared the cancer risk-related beliefs of 134 women with a personal history of breast cancer (affected group) and 80 women without breast cancer who had a family history of the disease (unaffected group), prior to risk assessment, using a mailed survey. This article reports their demographics, health characteristics, family history, and beliefs about cancer risk, risk factors, and genetic testing. Most participants were in their 40s (mean age = 47.9), Caucasian (79%), married (66%), and college-educated (60%), and had children (78%). Most women (87%) had a close relative with breast cancer and/or ovarian cancer. In general, both groups greatly overestimated near-term and lifetime cancer risk. Significantly more unaffected women believed they were at higher risk for breast cancer than affected women. Both groups expressed desire for, but lacked knowledge of, genetic testing. Nurses are in a prime position to assist women seeking GCRA by providing accurate information and emotional support regarding cancer risk, risk factors, and genetic testing.

Indications and use of palliative surgery-results of Society of Surgical Oncology survey.

BACKGROUND: Despite increasing attention to end-of-life care in oncology, palliative surgery (PS) remains poorly defined. A survey to test the definition, assess the extent of use, and evaluate attitudes and goals of surgeons regarding PS was devised. METHODS: A survey of Society of Surgical Oncology (SSO) members. RESULTS: 419 SSO members completed a 110-item survey. Surgeons estimated 21% of their cancer surgeries as palliative in nature. Forty-three percent of respondents felt PS was best defined based on pre-operative intent, 27% based on post-operative factors, and 30% on patient prognosis. Only 43% considered estimated patient survival time an important factor in defining PS, and 22% considered 5-year survival rate important. The vast majority (95%) considered tumor still evident following surgery in a patient with poor prognosis constituted PS. Most surgeons felt PS could be procedures due to generalized illness related to cancer (80%) or related to cancer treatment complications (76%). Patient symptom relief and pain relief were identified as the two most important goals in PS, with increased survival the least important. CONCLUSION: PS is a major portion of surgical oncology practice. Quality-of-life parameters, not patient survival, were identified as the most important goals of PS.
