Summary The 28-item GHQ was used to assess psychiatric morbidity in 302 women attending for routine breast cancer screening, 300 women attending for further investigation of a positive screening result and 150 women referred for investigation of breast symptoms. The GHQ-28 was administered on arrival at the relevant clinic and three months later. Medical records were used to determine the outcome of the clinic attendance. Women were classified into routinely screened women, women with false positive screening results, symptomatic women with a benign diagnosis, newly diagnosed cancer patients and previously treated cancer patients. When tested on arrival at the clinic, 25% of routinely screened, 30% of women with false positive results and 35% of symptomatic women with benign conditions were probable cases of psychiatric morbidity. The only statistically significant difference was between the routinely screened and symptomatic benign groups. Levels of anxiety were significantly higher in those with false positive results and in the symptomatic benign group than in the routinely screened. Three months later the prevalence of probable psychiatric morbidity had fallen to 19% in both the routinely screened and those with false positive results but remained significantly higher in the symptomatic benign group (31%). Probable cases of psychiatric morbidity among newly detected cancer patients rose from 34 to 46% over the 3-month period. Among women who had had breast cancer diagnosed in the past prevalence remained at 21 %. The prevalence of probable psychiatric morbidity in screened women is similar to that in the general population. Among women referred for further investigation because of a false positive screening result prevalence was only slightly increased and there was no evidence of a sustained increase in anxiety. Provided that delays are kept to a minimum and that women are kept informed, a breast cancer screening programme does not increase psychiatric morbidity. Further research is required in cancer patients to determine whether those diagnosed in asymptomatic women have a higher and more sustained degree of psychiatric morbidity than those diagnosed in women who are aware of symptoms.Concern has been expressed that screening for breast cancer may have adverse psychological effects. The invitation for screening may make women more aware of their vulnerability and hence increase anxiety. Recalling women who are found to have an abnormality on screening for further investigation (currently 5-10% of those screened in the UK) may cause distress which is hard to alleviate even when further investigations are negative. Those who are symptom-free on screening but are found to have cancer could find it especially hard to adapt to the diagnosis (Maguire, 1982).The first concern has been partially investigated in Edinburgh (Dean et al., 1986). It was found that women attending for screening had no excess psychiatric morbidity compared to other women in the same age-group, (although little is yet known about morbidi...
RESUMO.-[Anormalidades hematológicas, bioquímicas e hemostáticas de origem paraneoplásica em fêmeas caninas com neoplasia mamária.] Alterações laboratoriais de origem paraneoplásica são identificadas em diversos tipos de câncer de cães e gatos. Na medicina veteriná-ria, existem poucos estudos que correlacionam os achados laboratoriais anormais com o tipo e estadiamento tumorais, principalmente em cadelas com neoplasia mamária. O objetivo deste estudo foi avaliar as alterações hematológi-cas, bioquímicas e hemostáticas em cadelas com neoplasia mamária e relacioná-las com o estadiamento tumoral. Foram coletadas amostras de sangue de 24 fêmeas caninas, e os parâmetros hematológicos, bioquímicos e hemostáticos obtidos foram relacionados com o estadiamento tumoral, realizado através do exame físico, exames de imagem e avaliação histopatológica após remoção cirúrgica. Os grupos foram organizados de acordo com o estadiamento tumoral em: Grupo 1 (estádios I e II), grupo 2 (estádio III) e grupo 3 (estádios IV e V). Observou-se anemia, leucocitose neutrofílica, monocitose, eosinofilia, trombocitose, hipoalbuminemia, hipocalcemia, hipoglicemia e diminuição de ureia sanguínea. As variáveis CHCM, PPT e RDW foram relacionadas com o estadiamento tumoral, porém sem relevância clínica. Nos testes de coagulação, o TT e o fibrinogênio apresentaram diferença significativa entre os grupos, sendo associado com estadiamento tumoral. Os resultados sugerem in- Paraneoplastic laboratory abnormalities are identified in several types of cancers in dogs and cats. In veterinary medicine, particularly in mammary cancer, there are few studies that correlate abnormal laboratory findings with tumor type and staging. The aim of this study was to evaluate hematological, biochemical, and hemostatic abnormalities and correlate them with mammary tumor staging in female dogs with mammary cancer. Blood samples from 24 female dogs were evaluated, and the hematological, biochemical, and hemostatic parameters were correlated with tumor staging obtained by physical examination, imaging exams, and histopathological surgical biopsies. The groups were organized according to tumor staging: group 1 (stages I and II), group 2 (stage III), and group 3 (stages IV and V). Anemia, neutrophilic leukocytosis, monocytosis, eosinophilia, thrombocytosis, hypoalbuminemia, hypocalcemia, hypoglycemia, and low blood urea were observed. The variables MCHC, TPP, and RDW were correlated with tumor staging with no clinical relevance. Thrombin time and fibrinogen were significant between the groups in the coagulation test, being associated with tumor staging. The findings suggest influence of the proinflammatory cytokines released during tumor growth.INDEX TERMS: Hyperfibrinogenemia, mammary tumor staging, paraneoplastic syndromes, laboratory parameters.
