Bone scintigraphy in nonsurgically treated Ewing's sarcoma at diagnosis and follow-up: prognostic information of the primary tumor site.

In order to detect skeletal metastases in patients with Ewing's sarcoma, bone scanning is commonly used. However, little information is available about the scintigraphic aspects of the primary Ewing's sarcoma during non-surgical treatment and follow-up. We studied retrospectively the significance of bone scintigraphic findings at the primary tumor site of 58 patients with a Ewing's sarcoma. These patients had chemotherapy and radiotherapy. At presentation 53/58 patients showed an increased tracer uptake at the primary tumor site while 5 patients with a pelvic or sacral bone localization had a normal scan. Bone scans made during treatment and more than 2 years thereafter in the 32 eligible patients demonstrated three patterns. In 16 patients the hot spot disappeared and no local tumor recurrence was encountered. In the other 16 patients the high uptake at the primary tumor site either persisted or diminished first to a normal uptake after a median period of 18 months (range 12-36 months) and returned again to a high uptake within 6-12 months. In these patients local Ewing's sarcoma was still present in 13, while in the other 3 cases a benign disorder (fracture, ectopic bone formation) was the underlying cause. These findings suggest that in non-surgically treated Ewing's sarcoma persisting increased tracer uptake or its recurrence is highly suspicious for the presence of Ewing's sarcoma, while bone scans becoming negative and remaining so for more than 12 months suggest the absence of local tumor.

Attitudes about genetic testing for breast-ovarian cancer susceptibility.

PURPOSE: In anticipation of the availability of genetic testing for a breast-ovarian cancer susceptibility gene (BRCA1), this study examined interest in and expectations about the impact of a potential genetic test. PATIENTS AND METHODS: The subjects were 121 first-degree relatives (FDRs) of ovarian cancer patients. The design was cross-sectional. Subjects completed a structured telephone interview of attitudes about cancer and genetic testing, and self-report psychologic questionnaires to assess coping style and mood disturbance. RESULTS: Overall, 75% of FDRs said that they would definitely want to be tested for BRCA1 and 20% said they probably would. In bivariate analyses, interest was associated positively with education, perceived likelihood of being a gene carrier, perceived risk of ovarian cancer, ovarian cancer worries, and mood disturbance. In logistic regression analysis, perceived likelihood of being a gene carrier was associated strongly with interest (odds ratio, 3.7; P = .006). Results of stepwise linear regression modeling indicated that an anticipated negative impact of genetic testing was associated with being younger (beta = -.66, P = .009), having more mood disturbance (beta = .015, P = .01), and having an information-seeking coping style (beta = .19, P = .002). CONCLUSION: These results suggest that the demand for genetic testing for BRCA1 among FDRs of cancer patients may be great. Moreover, those who elect to participate may represent a more psychologically vulnerable subgroup of high-risk women.

Younger women at increased risk for breast cancer: perceived risk, psychological well-being, and surveillance behavior.

The problem of breast cancer in younger women has received increased attention in recent years. As yet, however, little is known about the surveillance patterns and psychological characteristics of younger women who are at increased risk for this disease. This report presents a summary of preliminary data on risk perceptions, surveillance behaviors, and psychological well-being among women with a family history of breast cancer, with particular attention to younger women (under age 50). These data show that over three fourths of women aged 29 and younger hold the belief that they are likely to develop breast cancer; this finding was not significantly different in other age groups. Surprisingly, over one third of women aged 29 and younger had received mammograms; over one half of women aged 30-34 had mammograms; and over three fourths of women aged 35 and older had mammograms. As many as one half of women aged 35-39 had mammograms within the past year. Serious psychological morbidity was not noted in the samples; however, one third of women of all ages reported breast cancer worries that impair their daily functioning. Psychological distress was associated with nonadherence to mammography and with both infrequent and excessive breast self-examination practice. These data provide the basis for recommendations for research on breast cancer risk counselling for younger women.

Communication between patients with breast cancer and health care providers. Determinants and implications.

BACKGROUND: This study evaluated the perceptions of patients with breast cancer of their medical interactions with providers. The determinants and psychological consequences of communication problems also were examined. METHODS: Ninety-seven patients with Stage I or II breast cancer completed a set of validated questionnaires before initiating postoperative therapy. Data on psychological distress were collected at baseline and 3-month follow-up, and multivariate models were fit to explain the relationship between pretreatment communication problems and subsequent psychological distress. Data on clinical variables were abstracted from medical records. RESULTS: A substantial proportion of patients (84%) reported difficulties communicating with the medical team. Communication problems were more common among patients who were less optimistic about their disease and had less assertive coping styles. Patient-reported communication problems were associated with increased anxiety, depression anger, and confusion at the 3-month follow-up. The association between communication problems and mood disturbance remained significant, although small, after adjusting for baseline mood disturbance, demographic, clinical, and coping style variables. CONCLUSION: Interventions that enhance communication between patients with breast cancer and their providers may improve patients' psychological adjustment to treatment. Conversely, interventions that lower distress and modify coping style may enhance communication.

Mammography adherence and psychological distress among women at risk for breast cancer.

BACKGROUND: Previous studies estimate that first-degree relatives of women with breast cancer have a twofold to 10-fold increased risk of developing breast cancer. Recently, attention has focused on the mammography screening practices of women who are at high risk for breast cancer. PURPOSE: Our purpose was to characterize mammography screening practices in a sample of first-degree relatives of breast cancer patients and to identify variables that may serve as barriers to or facilitators of adherence to mammography. METHODS: Cross-sectional (rather than prospective) data were collected by telephone interviews with 140 women aged 35-79 years who had a family history of breast cancer in at least one first-degree relative (mother, sister, or daughter). Data were recorded on mammography screening patterns, depression, stress impact, and breast cancer worries. RESULTS: Women whose mammography history adhered to age-specific recommendations varied by age: 76% of first-degree relatives aged 35-39 years, 86% aged 40-49 years, and 63% aged 50 years or more. In bivariate analyses, level of education (P = .001), employment (P = .046), and time since diagnosis of the index patient (P = .044) were significantly and positively associated with mammography adherence. Variables associated negatively with adherence included age (P = .019), intrusive thoughts about breast cancer (P = .042), and breast cancer worries that interfered with daily functioning (P = .004). Multivariate analysis by logistic regression indicated that only breast cancer worries (odds ratio [OR] = 2.5; 95% confidence interval [CI] = 1.09-5.9) and education (OR = 4.8; CI = 1.6-14.3) were significant independent predictors of mammography adherence. CONCLUSIONS: This study suggests that most women at high risk for breast cancer adhere to the recommended mammography screening guidelines of the National Cancer Institute. However, rates of adherence among high-risk women aged 50 years and older are suboptimal; only 63% of these women received annual screening mammograms, and 13% had never been screened. Breast cancer worries may pose a barrier to mammography adherence among high-risk women, particularly those with less formal education. IMPLICATIONS: Prospective longitudinal studies are needed to validate the present findings and to evaluate the impact of psychoeducational interventions for women with affected first-degree relatives.

Breast cancer screening practices among retirement community women.

BACKGROUND: The purposes of this study were (a) to learn more about the existing breast cancer screening practices of women age 65 and older and (b) to identify factors related to breast cancer screening. METHOD: A random sample of 752 women age 65 and older residing in independent living apartments in eight retirement communities was selected to participate in a survey of breast cancer screening practices and related factors. A total of 616 surveys were complete, yielding a response rate of 82%; of those, 571 of the surveys were administered by telephone, with the remaining 45 administered in person. RESULTS: Thirty-eight percent of the women reported having had a mammogram within the past year, 53% had a clinical breast exam, and 39% reported performing monthly breast self-examination. The percentage of women reporting either annual clinical breast examinations or mammography decreased with increasing age. Results of a logistic regression analysis found that having discussed mammography with a physician, believing in the need for mammography, having no mammography-related concerns, and the combination of personal experience with breast cancer and having had a clinical breast examination in the past year were all independently related to having had a mammogram within the past year (P < 0.05). CONCLUSION: In order to increase older women's participation in screening, particularly in mammography, educational interventions need to be developed and directed both to older women and to their physicians.

Interest in genetic testing for colon cancer susceptibility: cognitive and emotional correlates.

BACKGROUND: Recent advances in human genetics have led to the identification of markers for cancer susceptibility. Nevertheless, little is known about the public's interest in clinical genetic testing for cancer-related markers. METHODS: A random-digit-dial telephone survey of 401 adult residents of Utah was conducted during the summer of 1990. Respondents were randomized to one of three question frames and asked about their interest in a potential genetic test for colon cancer susceptibility. They were also asked to rate their risk for colon cancer, how often they worried about contracting any type of cancer, and how often they felt worried and nervous during the past year (trait anxiety). RESULTS: Eighty-three percent of respondents expressed interest in genetic testing. Level of interest was most strongly correlated with perceived risk for colon cancer (r = 0.21, P < 0.001). Responses were not affected by the use of different question frames. CONCLUSIONS: These results show a high level of public interest in genetic testing for colon cancer susceptibility. The data also suggest that anxiety does not undermine interest, but future research must determine whether this relationship is limited to hypothetical judgments such as those studied here.

Adherence and psychological adjustment among women at high risk for breast cancer.

Increasingly, women with a positive family history of breast cancer are being targeted for cancer prevention and control efforts. Two findings have been demonstrated consistently across studies of this high risk population. First, these women often have high levels of psychological distress, as well as persistent and intrusive worries about developing breast cancer. Second, despite their increased risk for developing breast cancer, a substantial proportion of these women do not adhere to recommended breast cancer screening guidelines. There is growing evidence that psychological distress is an important barrier to adherence among high risk women. Despite this, little is known about how to intervene to improve psychological adjustment and adherence in this population. In the present paper, we review the literature on adherence and psychological adjustment in women who are at increased risk for breast cancer because of a positive family history of disease. This review provides the basis for a discussion of potential intervention strategies designed to increase adherence and reduce psychological distress in this population. Finally, we present some of the psychological implications of recent developments in genetic testing for breast cancer susceptibility.

Ovarian cancer risk counseling: a guide for the practitioner.

Epithelial ovarian cancer is the most common gynecologic cancer diagnosed in women in the United States, with over 20,000 newly diagnosed cases per year. Over 70% of these patients present with advanced, stage III or IV disease, resulting in more than 13,000 deaths each year. This figure is all the more tragic given the long-term disease-free survival of approximately 85% for early stage disease. The natural history of the disease is poorly understood but is characterized by an insidious onset with vague, non-specific symptoms (which are commonly overlooked), and a high but often transient response to current surgical and chemotherapeutic approaches. It is commonly associated with a prolonged and painful death accompanied by repeat bowel obstructions, malnutrition, and immunologic compromise. In addition to the pain and suffering and loss of life of those affected with the disease, there is a profound and long-lasting impact on the entire family who experience the loss.

Factors associated with adherence to breast cancer screening among working women.

This study identified sociodemographic, knowledge, attitude, and social influence correlates of obtaining mammograms among employed women age 40 and over. Telephone interviews were conducted with 798 women who worked at 39 different work sites. Eighty-four percent of respondents had ever had a mammogram, and 72% had had one at the recommended interval for their age group. The only personal characteristic that was associated with past mammography use was having a co-worker, friend, or relative with a history of breast cancer. Logistic regression analyses indicated that a doctor's advice to have a mammogram, knowledge of screening guidelines, knowing someone with breast cancer, and the beliefs that mammography is effective and that mammography is necessary in the absence of symptoms were associated independently with past use of mammography. Three factors contributed independently to explaining adherence to mammography guidelines: younger age, knowledge of guidelines for one's own age group, and the belief that breast cancer is curable. The findings suggest that emphasizing the recommended guidelines, the need for and benefits of mammography in educational programs, and offering low-cost or free mammography at the workplace, can further increase appropriate utilization among working women.

Telephone counseling improves adherence to colposcopy among lower-income minority women.

PURPOSE: A randomized trial was conducted to evaluate the impact of a telephone counseling intervention to improve patient adherence to colposcopic examination for suspected cervical intraepithelial neoplasia (CIN). METHODS: Subjects were lower-income, minority women who missed a scheduled initial appointment for colposcopy at an urban medical clinic. Patients were randomly assigned to either a control condition (n = 42) or a telephone counseling condition (n = 48). The 15-minute, structured telephone counseling intervention protocol addressed educational, psychosocial, and practical barriers to colposcopy adherence. RESULTS: The most common patient-reported barriers to colposcopy adherence included a lack of understanding of the purpose of colposcopy (50%), worry about or fear of cancer (25%), and forgetting (23%). Telephone counseling was found to be highly effective in addressing these barriers and improving adherence to diagnostic follow-up and treatment. Of patients in the control condition, 43% complied with a rescheduled colposcopy appointment, compared with 67% in the telephone counseling condition. Logistic regression analysis indicated that the effect of telephone counseling was independent of sociodemographic confounder variables (odds ratio = 2.6; P less than .003). Additionally, 74% of patients who received the initial telephone counseling adhered to recommended treatment, compared with 53% of patients in the control condition. CONCLUSION: Brief, structured telephone contact may be a cost-effective mechanism for improving adherence to diagnostic follow-up and treatment for a variety of cancer screening tests.

The impact of mailing psychoeducational materials to women with abnormal mammograms.

A randomized trial was conducted to evaluate the impact of mailed psychoeducational materials on adherence to subsequent annual mammography among women with prior abnormal mammograms. The results showed a 13% increment in adherence among women who received this intervention. This effect was independent of all sociodemographic and medical variables examined. We conclude that mailed psychoeducational materials may be an effective mechanism to improve adherence among women with abnormal mammogram results.

Psychological and behavioral implications of abnormal mammograms.

OBJECTIVE: To evaluate women's psychological responses to abnormal mammograms and the effect on mammography adherence. To identify psychological responses and other factors that predict mammography adherence in women with normal or abnormal mammograms. DESIGN: Survey study with prospective analysis of factors associated with mammography adherence. SETTING: Health Maintenance Organization of Pennsylvania and New Jersey (HMO PA/NJ). PATIENTS: Study patients, members of HMO PA/NJ who were 50 years of age or older, and who had had mammography done 3 months earlier, included women with normal mammograms (n = 121), women with low-suspicion mammograms (n = 119), and women with high-suspicion mammograms (n = 68), but not women with breast cancer. MEASUREMENTS: Psychological responses 3 months after mammography and adherence to subsequent annual mammography were assessed. MAIN RESULTS: Women with high-suspicion mammograms had substantial mammography-related anxiety (47%) and worries about breast cancer (41%). Such worries affected the moods (26%) and daily functioning (17%) of these women, despite diagnostic evaluation excluding malignancy. For each variable, a consistent trend (P greater than 0.05) was seen with degree of mammogram abnormality. Sixty-eight percent of women with normal results, 78% of women with low-suspicion results, and 74% of women with high-suspicion results obtained their subsequent annual mammograms (P greater than 0.05). The number of previous mammograms (odds ratio, 3.2; 95% CI, 1.6 to 6.2) and the effect of the previous results on concerns about breast cancer (odds ratio, 0.5; CI, 0.2 to 1.0) were independent predictors of adherence in logistic regression analyses (P less than 0.05). CONCLUSIONS: A substantial proportion of women with suspicious mammograms have psychological difficulties, even after learning that they do not have cancer. Such sequelae do not appear to interfere with subsequent adherence.

Contributions of public health to patient compliance.

This paper discusses the contributions of public health to compliance in five areas: clinical trials, smoking cessation, dietary compliance, breast cancer screening and hypertension control. Public health programs have been based on a number of theoretical foundations, most notably, social learning theory and the health belief model. Social marketing, community organization, and, more recently, consumer information processing models also are important. The strongest public health programs embody an ecological approach, with interventions directed not only at individuals, but also at groups, communities and changing institutional norms. Among the most important contributions of public health interventions are: multiple levels of intervention and evaluation, tailoring to target audiences, use of social support and community organization for behavior change. Together, community health and clinical compliance-enhancing strategies can exert a synergistic impact on health behavior change.

Adverse psychologic consequences of positive cytologic cervical screening.

Cervical cancer is still widely prevalent in the female population. This study explores the relationship of cervical cancer screening, positive versus negative Papanicolaou's test results, and psychologic status among lower-income minority women. All patients were interviewed 3 months after they had received initial test results. One hundred six women with normal Papanicolaou's test results were compared with 118 women who were referred for colposcopic examination for follow-up of positive test results. Women with positive Papanicolaou's-test results showed statistically significant elevations in worries about cancer and impairments in mood, daily activities, sexual interest, and sleep patterns. More fine-grained analyses revealed that the effects of positive results were most pronounced among those women who did not comply with colposcopy (n = 53). These findings suggest that lack of compliance with follow-up may maintain high levels of uncertainty about disease and may interfere with successful psychologic adaptation. Health education targeted to psychologically vulnerable individuals may reduce psychologic distress and enhance compliance.

Psychological side effects of breast cancer screening.

Evaluated the impact of receiving abnormal mammogram results on women's anxiety and breast cancer worries and on their breast self-examination (BSE) frequency and intentions to obtain subsequent mammograms. A telephone survey was conducted with 308 women 50 years old and older approximately 3 months following a screening mammogram. Subjects included women with suspicious abnormal mammograms, nonsuspicious abnormal mammograms, and normal mammograms. Women with suspicious abnormal mammograms exhibited significantly elevated levels of mammography-related anxiety and breast cancer worries that interfered with their moods and functioning, despite the fact that diagnostic work-ups had ruled out breast cancer. Women with moderate levels of impairment in mood or functioning were more likely to practice monthly BSE than women with either high or low levels of impairment. Breast cancer worries, perceived susceptibility to breast cancer, and physician encouragement to get mammograms all exhibited independent positive relationships to mammogram intentions.
