Increasing cervical cancer screening among minority elderly. Education and on-site services increase screening.

Older women participate in cervical cancer screening less regularly than do younger women. As a consequence, more lesions are found in more advanced and less curable stages in older women. Elderly black and Hispanic women have had lower rates of participation in cervical cancer screening than white women. There is a marked, inverse relationship between the stage of cervical cancer at diagnosis and the 5-year survival rate. The rate of cervical cancer screening among older women can be increased by offering education about Pap tests and onsite cervical cancer screening in housing for the elderly.

[Screening examination for prostate cancer. Early detection and mass screening].

The significance of symptoms, digital rectal examination (DRE), transrectal ultrasonography (TRUS) and prostatic specific antigen (PSA) as aids in the early detection of prostate cancer was investigated. In number of studies, sensitivity of DRE is lower than that of TRUS but specificity of DRE is adversely higher than that of TRUS. PSA was an excellent means to observe clinical course of prostate cancer patients but have proven to be insensitive and nonspecific to detect early stage prostate cancer. There is certainly no single test that can be applied reliable to detect the presence of prostate cancer at present. The use of three screening modalities must be recommended to improve the detection rate. Mass screening program in Gunma Prefecture has been being studied since 1981. In this paper, we demonstrated that this screening program is successful to detect early prostate cancer with high detection rate (0.8%), improves the survival rates comparing to those of patients detected by outpatient clinics and the tests applied in this program prove relatively high specificity and sensitivity. To prove the significance of mass screening program, pilot studies in well executed randomized prospective protocols are urgently needed. To achieve this purpose, it is necessary to organize a cooperative study group since approximate 50,000 to 100,000 subjects should be examined in this protocol.

The changing pattern of prostate cancer at the time of diagnosis: characteristics of screen detected prostate cancer in a population based screening study.

PURPOSE: We describe the clinical and pathological features of prostate cancer diagnosed through serum prostate specific antigen (PSA), digital rectal examination and transrectal ultrasonography in a population based randomized screening study. MATERIALS AND METHODS: Between November 1993 and June 1997, 20,632 volunteers 55 to 76 years old were included in the study. In the screening arm 9,776 men underwent digital rectal examination, transrectal ultrasound and serum PSA determination. Biopsies were taken if the digital rectal examination and/or transrectal ultrasound findings were abnormal or if PSA was 4 ng/ml or greater. A total of 2,262 men underwent biopsy and 474 cases of prostate cancer were diagnosed. RESULTS: The pretreatment data were complete in 459 men, of whom 78% had clinically organ confined disease. Bone or lymph node metastases were seen in 8 cases (1.7%). Of 172 men who underwent radical prostatectomy 2 had lymph node metastases. Overall 66.3% of men treated with radical prostatectomy had organ confined disease. CONCLUSIONS: Comparison of the characteristics of prostate cancer detected through screening of the general population with those in a population based cohort of men in which there was no organized screening revealed stage reduction, primarily with regard to number of metastatic cases. Whether this stage reduction will lead to a decrease in disease specific mortality remains unknown until the study is completed and the end point of prostate cancer specific mortality is evaluated.

Community-based interventions to improve breast and cervical cancer screening: results of the Forsyth County Cancer Screening (FoCaS) Project.

The FoCaS (Forsyth County Cancer Screening) Project was one of six projects funded by the National Cancer Institute "Public Health Approaches to Breast and Cervical Cancer" initiative. The goal of this project was to improve the use of breast and cervical cancer screening among low-income, predominately African-American, women age 40 and older. Strategies implemented in the intervention city included public health clinic in-reach strategies (chart reminders, exam room prompts, in-service meetings, and patient-directed literature) and community outreach strategies (educational sessions, literature distribution, community events, media, and church programs). Baseline and follow-up data from independent cross-sectional samples in both the intervention and comparison cities were used to evaluate the effects of the intervention program. A total of 248 women were surveyed at baseline, and 302 women were surveyed 3 years later at follow-up. The proportion of women reporting regular use of mammography increased (31 to 56%; P < 0.001) in the intervention city. In the comparison city, a nonsignificant (ns) increase in mammography utilization was observed (33 to 40%; P = ns). Pap smear screening rates also improved in the intervention city (73 to 87%; P = 0.003) but declined in the comparison city (67 to 60%; P = ns). These relationships hold in multivariate models. The results suggest that a multifaceted intervention can improve screening rates in low-income populations. These results have important implications for community-based research and efforts in underserved populations.

[Cervical cancer screening for high risk women: is it possible? Results of a cervical cancer screening program in three suburban districts of Lyon].

Between november 1993 and october 1996, a cervical screening program was proposed for women 25-65-year-old who tend to have little or no medical supervision, in three suburban districts of Lyon. The data and results of the two last Pap-smears have been collected together with details of gynecological follow-up. Both general practitioners and gynaecologists were actively involved. A total of 3,792 women (12.3% of the target) were registered, with a larger proportion of women over 60 (17.7%). According to the "Consensus of Lille", only 403 women (34.4%) had adequate screening (over 50 y: 25.8%, 35-49 y: 39.4%, 25-35 y: 36.5%) and 2,489 women had inappropriate gynaecological follow-up: no smear for 185 women (4.9%) and inadequate schedule of follow-up visits for 476 others (12.5%). Missing data (date or results of Pap smear) were noted for 1,828 patients (48.2%). The screening procedure for women over 50 years was carried out mainly by general practitioner. Of 3,127 registered smears, 62 positive results were found (2.1%). Of these women, 9 were lost to follow-up and 4 did not have appropriate tests. Others results were: 27 negative further investigations, 9 CIN1, 7 CIN2, 3 CIN3, 1 in situ carcinoma and 2 invasive carcinoma. Despite low participation, this pilot study indicates that a procedure can be established to integrate high risk women in cervical cancer screening programme. Active participation of general practitioners is essential.

Screening for genetic disorders among Jews: how should the Tay-Sachs screening program be continued?

The screening program in Israel for Tay-Sachs disease has proven very successful, giving Jewish couples a choice not to have affected children. The technology of carrier detection is now possible in several other severe genetic diseases that are relatively frequent among Jews. Due to the current confusion, a policy is needed to determine how the TSD screening program should be continued in the Israeli Jewish population. We propose that such a screening program include only mutations agreed by consensus as causing a disease severe enough to warrant the possibility of therapeutic abortion. We also propose that general screening include only mutations that are relatively frequent, taking into account the carrier frequencies in the Israeli Jewish population.

Screening for galactosemia: Philippines experience. Newborn Screening Study Group.

Galactosemia is an inborn error of galactose metabolism due to a deficiency of any of the galactokinase, galactose-1-phosphate uridyl transferase (GALT), or epimerase enzymes. The Philippines, with its pilot newborn screening project, has been screening for this disorder for 2 years now. A total of 62,841 babies have been screened using the galactose and galactose-1-phosphate spot test. Confirmatory testing is done by the newborn screening laboratory of the The New Children's Hospital in Westmead, Australia. Two cases of galactosemia: 1 classical galactosemia and 1 galactokinase deficiency have so far been confirmed. Clinical review, problems encountered, and management are described. Long-term outcome of these patients, however, is yet to be determined.

Prostate cancer screening within a prostate specific antigen range of 3 to 3.9 ng./ml.: a comparison of digital rectal examination and free prostate specific antigen as supplemental screening tests.

PURPOSE: Performing biopsy in all men with a serum prostate specific antigen (PSA) of 3 to 3.9 ng./ml. increases the sensitivity of prostate cancer screening compared with a PSA cutoff of 4 ng./ml. but decreases specificity and may contribute to over diagnosis. Therefore, we evaluated the detection rate and specificity attributable to digital rectal examination and percent free PSA within the PSA range of 3 to 3.9 ng./ml. MATERIALS AND METHODS: Serum PSA was determined in 20,716 participants in the Finnish population based screening trial. Supplementary digital rectal examination was offered to men with a PSA of 3 to 3.9 ng./ml. during 1996 to 1998 (protocol 1). Those with a suspicious digital rectal examination finding were referred for biopsy. The screening algorithm was modified by substituting percent free PSA for digital rectal examination with a cutoff of 16% as a biopsy criterion in 1999 (protocol 2). In addition, biopsies were performed in all men with PSA 4 ng./ml. or greater. RESULTS: A total of 23 cancers (2.9%) were detected by digital rectal examination among 801 men, while percent-free PSA resulted in the diagnosis of 13 cases (4.8%) among 270 men with a PSA of 3 to 3.9 ng./ml. The detection rate of tumors with a Gleason score of 5 or greater increased from 1.6% (13 of 801 cases) to 4.4% (12 of 270) in the modified screening program. The PSA cutoff of 3 ng./ml. alone showed 88.6% and 87.5% specificity in protocols 1 and 2 but specificity increased to 93.3% and 91.7% using digital rectal examination and percent free PSA, respectively. CONCLUSIONS: Using percent free PSA increased the detection rate of aggressive disease compared with digital rectal examination and provided higher specificity than PSA alone.

Perceived barriers and benefits to colon cancer screening among African Americans in North Carolina: how does perception relate to screening behavior?

This study investigated perceived barriers and benefits, as conceptualized by the Health Belief Model,in relation to screening for colorectal cancer (CRC) among African-American adults participating in a church-based health promotion program. CRC is one of the most common cancers and is the second leading cause of cancer death for men and women. Screening can be effective at detecting cancer at treatable stages, but a large proportion of people at risk have not been screened or are not screened regularly, as recommended by national guidelines. In this study, logistic regression was used to assess the relation of barriers and benefits to self-reported history of fecal occult blood testing (FOBT), flexible sigmoidoscopy, and colonoscopy. Barriers were significantly negatively related to recent FOBT and recent sigmoidoscopy. Benefits were significantly related to having a recent sigmoidoscopy and a recent colonoscopy but not to recent FOBT. Results suggest that the way people perceive sigmoidoscopy and colonoscopy may differ from FOBT with respect to the relative importance of perceived benefits versus barriers. Findings are discussed within the context of these Health Belief Model constructs and implications for health promotion programming.

[Evaluation of genetic screening. The problem of hidden value judgements, conceptual arbitrary attitudes and methodological leeway in the so-called screening process].

Population-wide genetic screenings can multiply benefits, but may also increase risks and other adverse effects of genetic testing. Insofar, there is a particular need for legitimization of genetic screenings. Health economic calculus and the so-called "screening ratios" aim to relate information about potential costs to potential benefits. Their implicit claim of being rational, however, can only be realised partially, since each concept is based on a number of value judgements allowing for different decisions, which can be a critical outcome factor. All the more so, since different players use different ratios. Against this background, disclosure of normative foundations and perspectives in cost-benefit ratios of genetic screenings seems to be imperative.

Prevention and screening. Part II: Critical appraisal of articles on screening.

Currently, a substantial part of clinical practice is involved with health maintenance and disease prevention. However, there continue to be deficiencies in the delivery of preventive care, and it is sometimes difficult to identify which interventions are effective--for lack of randomized clinical trials--and the theoretical basis of this approach is not always clear. In the previous paper published in the Journal, we presented the general conceptual principles of preventive medicine, starting with levels of prevention and followed by the criteria for selecting a preventive intervention. Regarding the latter, the characteristics of the disease to be screened and the respective screening test were discussed, as well as therapy for positive cases. Finally, we discussed the possible consequences of screening for disease. In this paper we present guidelines for the critical appraisal of articles on screening.

[Surgical treatment of breast tumors in patients after mammography screening. Personal experience in the first 3 years of operation of the screening program in the province of Verona].

A mammographic screening program was started in 1999 in the Province of Verona and was offered to women aged 50-69. The purpose of this study was to analyse and compare our data, particularly the type of surgery and histotype, with the literature data where no screening program was implemented. During the first three years of the screening, 113 patients underwent surgical treatment in our Institute. The histology of the mammary lesions was benign neoplasia in 28 (24.7%) and breast cancer in 85 (75.3%) patients. Seventy-three women (85.9%) with malignant neoplasms were submitted to conservative treatment. Mastectomy was performed in 12 (14.1%) patients, 8 of whom with immediate breast reconstruction. Patients coming from screening programs benefit in a high percentage of cases from conservative treatment, which, together with the reduced aggressiveness of the cancers, permits alternative treatments for the axillary lymph nodes and a reduction in adjuvant chemotherapy.

[Evaluation of cancer screening programs in relation to screening recommendations].

Cancer screening programs have been conducted in Japan as a public health policy without evidence that the programs were effective at reducing the mortality. To achieve mortality reduction in the country, organized screening is obviously necessary. To learn from international guidelines on cancer screening, the recommendations from the American Cancer Society was reviewed and summarized. A recent revision of the recommendation of Japanese screening programs for breast cancer and uterine cancer were also referred.

[Mass screening for detection of infants with hearing impairment. I. Methods and process of the mass screening examination for hearing].

A mass screening program to detect infants with hearing impairment was conducted at the Sapporo Toyohira Health Center in Hokkaido. Between April 1988 and March 1990, 5,676 infants were screened by a questionnaire at the time of the 4-month health examination. Out of the 5,080 cases who could be followed, nine infants underwent thorough otolaryngological examinations, and among the nine infants three cases with hearing impairment were detected. The prevalence rate was, therefore, one case out of 1,693 infants. Although false positive cases amounted to about 5% of the initial infant population, true positive cases were confirmed out of the initially screened positive cases at 7 or 10 months of age through other questionnaires and through behavioral hearing tests using a bell. No false negative cases were found. Inclusion of this mass screening system in the routine child health program is recommended.

Diabetic retinopathy screening model for rural population: awareness and screening methodology.

CONTEXT: Worldwide, the prevalence of diabetic retinopathy is increasing at an alarming rate. WHO has predicted that in India the number of adults with diabetes will be the highest in the world: from 19 million in 1995 to 80 million in 2030. Although originally thought to be a disease of an urban population, the prevalence of diabetes mellitus is increasing in rural areas as well. The socioeconomic burden resulting from visual impairment or blindness caused by diabetic retinopathy, particularly in the working age group, is a serious concern. ISSUE: In order to combat diabetic retinopathy related blindness, Sankara Nethralaya, the premier eye institute of India, in collaboration with the Lions Clubs International Foundation (LCIF) and the RD Tata Trust, Mumbai, India launched a major diabetic retinopathy screening program in the rural community of South India. The objectives were to create awareness among the rural population of diabetic retinopathy with emphasis on early detection, to conduct diabetes and diabetic retinopathy screening camps, and to bring to the base hospital patients who have sight-threatening diabetic retinopathy, for ancillary investigations such as fluorescein angiography, ultrasound and to perform laser photocoagulation or vitreous surgery, or both. Other objectives included training general ophthalmologists and general physicians in order to develop an integrated diabetic retinopathy model. To address the question as to why certain individuals run the risk of developing sight threatening diabetic retinopathy, biochemical and genetic factors were also studied. The program was launched in June 2003 and 3 rural districts have been screened. To the time of writing, 128 screening camps had been organized, 103 awareness meetings conducted, 23 ophthalmologists trained and 43 general physicians attended the continuing medical education program on diabetic retinopathy. LESSONS: The key elements in the successful implementation of this program have been a team approach, involvement of community leaders and voluntary organizations, and support of the district and state administrators.

Should we screen for Alzheimer's disease? A review of the evidence for and against screening Alzheimer's disease in primary care practice.

Fewer than one-half of all Alzheimer's disease (AD) patients are currently diagnosed; approximately 25% are treated with antidementia compounds. Screening has been proposed to help combat underdiagnosis of AD. An emerging consensus suggest that the three keys to the successful treatment of Alzheimer's disease are early detection, use of currently approved medications to provide symptomatic treatment, and development of medications to slow and eventually halt disease progression. If early detection of Alzheimer's disease is the first step, screening would seem to be an important strategy. We review the arguments for and against screening and suggest several strategies and instruments that may be helpful in the context of screening for Alzheimer's disease in primary care practice.

Effect of screening result on waiting times to assessment and breast cancer diagnosis: results from the Ontario Breast Screening Program.

BACKGROUND: The effect of severity of screening result on delays to diagnosis has primarily been examined for mammographic abnormalities. This study will examine delays to assessment and diagnosis for women with an abnormal mammogram compared to women with an abnormal clinical breast examination (CBE) or abnormal CBE and mammogram. METHODS: Using data routinely collected by Ontario Breast Screening Program (OBSP), 12,675 women aged 50 to 69 with an abnormal screening result between January 1, 2000 and December 31, 2000 were followed prospectively to the completion of their assessment process. Median waiting times from abnormal screen to first assessment procedure and diagnosis were compared by modality of referral and among women with a breast cancer diagnosis by prognostic features. RESULTS: The median waiting time to first assessment and to diagnosis was significantly longer for women with only a clinical abnormality compared to women with a mammographic abnormality. In addition, women diagnosed with cancers of larger size had longer delays when the abnormality was detected only clinically. However, women referred by both modalities had significantly shorter waiting times to first assessment procedure and to diagnosis of poor prognosis cancers compared to women referred by mammography alone. INTERPRETATION: Women with an abnormal CBE and mammogram are assessed more promptly and have shorter diagnostic times. However, women with only a CBE abnormality had delays to diagnosis as a result of longer waiting times to first assessment procedure. Integration of the OBSP with assessment centres should improve times to diagnosis irrespective of modality of referral.
