- The aim of this study was to compare lymph node involvement of breast cancer cases detected at mammography screening with clinically-detected cases. During a 3-year period, 273 primary breast cancers were detected in a population-based screening programme, and 149 primary breast cancers were diagnosed clinically. Lymph node involvement was evaluated in univariate and multivariate logistic regression models correcting for tumour size, histological grade, steroid receptor status and DNA-ploidy. Patients with screen-detected cancers had a low relative risk of having lymph node metastases (univariate, OR = 0.31; 95% confidence interval = 0.19-0.52). In the multivariate logistic regression model, the relative risk was halved (OR = 0.47; 0.28-0.78). The reduced risk was more pronounced for women younger than 50 years of age compared to older women. The risk for screen-detected cases of having lymph node metastases at diagnosis was statistically significantly lower than for clinically-detected cases. The marked reduction, even when correcting for tumour size, makes it less likely that factors such as detection of clinically innocent tumours, length bias sampling or clinical symptoms related to axillary metastases can explain the whole difference. The results indicate at least part of the effect may be explained by tumour progression in the late preclinical detectable phase.

- The aim of this study was to investigate the possibility of predicting anxiety and depression 6 months after the cancer diagnosis on the basis of measures of anxiety, depression (Hospital Anxiety and Depression, HAD scale), subjective distress (Impact of Event, IES scale) and some aspects of social support in connection with the diagnosis. A further purpose was to attempt identification of individual patients at risk of prolonged psychological distress, and to develop an easily applicable clinical tool for such detection. A consecutive population-based series of 522 newly diagnosed patients with breast, colorectal, gastric and prostate cancer were interviewed in connection with the diagnosis and 6 months later. Anxiety and depression close to the diagnosis explained 39% of the variance in anxiety and depression 6 months later. Patients scoring as doubtful cases/cases for HAD anxiety and/or depression were more than 11 times more likely than non-cases to score as doubtful cases/cases at 6 months. Addition:ll risk factors were having an advanced disease and nobody in addition to the family to rely on in case of difficulties. Levels of anxiety and depression at diagnosis predict a similar status 6 months later. The results also indicate that the HAD scale in combination with a single question about social support may be a suitable screening tool for clinical use.

Telomeres and telomerase in normal and malignant haematopoietic cells
- 1997

- The normal haematopoietic system harbours telomerase-competent cells with a capacity to upregulate the activity to notable levels in a telomere length-independent manner. Strong telomerase activity is found in progenitor stem cells and activated lymphocytes in vitro as well as in vivo, indicating that cells with high growth requirements can readily upregulate telomerase. Despite detection of telomerase activity, a gradual telomere erosion occurs in stem cells and lymphocytes, with significantly shortened telomeres at higher ages, a phenomenon that might be of importance for developing immunosenescence and exhausted haematopoiesis. In malignant haematopoietic disorders telomerase activity is a general finding with large differences in activity levels. The strongest telomerase expression has been shown in acute leukaemias and non-Hodgkin's lymphomas, especially high grade cases. There are indications that the level of activity might parallel tumour progression and be of prognostic relevance, but studies of larger patient materials are needed. An association between the cell cycle and telomerase activity exists, especially for normal haematopoietic cells, and induction of a differentiation programme in immortalised cell lines downregulates telomerase activity. The expression of telomerase activity seems to be regulated at different levels, since for immature bone marrow cells the level of activity seemed to parallel better the phenotype than the proliferation state. The frequent expression of telomerase in leukaemias and lymphomas makes these disorders interesting targets for future anti-telomerase therapy.

Affected sexuality, body image and health related quality of life in patients treated for hematologic malignancies - a one year follow-up

- Background: Longitudinal studies examining sexuality, body image and health-related quality of life (HRQoL) in middle-aged and elderly patients treated with chemotherapy or chemoimmunotherapy for hematologic malignancies are lacking. The aim of this study was to describe and explore changes in sexuality, body image and HRQoL in patients treatedfor hematologic malignancies, from baseline until twelve months after treatment.Material and Methods: Patients above 45 years treated for Diffuse large B-cell Lymphoma (DLBCL), Chronic Lymphocytic Leukemia (CLL) or Acute Myeloid Leukemia (AML). Data were collected at baseline (n = 32), one (n = 25), six (n = 20) and 12 months (n = 19) after treatment by means of three instruments: The Sexual Adjustment Questionnaire (SAQ), TheBody Image Scale (BIS) and The European Organization for Research and Treatment of Cancer Quality of Life questionnaires (EORTC QLQ-C30, version 3). Descriptive- and non-parametric statistics were used.Results: One month after treatment scores were lowered regarding sexual interest (P = 0.005), sexual function (P = 0.031), sexual satisfaction (P = 0.016, P = 0.004) and sexual relationship. After six months the patient reported scores had returned almost entirely to baseline scores, except for sexual relationship. At 12 months, sexual relationship was still negatively affected. Body image was reported to be affected in a low extent duringthe study period. After six and 12 months, body image was reported to not be affected at all by 50% and 53%, respectively. However, women reported body-image to be more affected than men at one (P = 0.01) and 12 months (p = 0.021). Regarding HRQoL, patients reported gradually statistically significant improved scores during the study period.Conclusion: In this study, sexuality, body image and HRQoL became negatively affected in patients with hematologic malignancies 45 years and older during treatment. Improvements were gradually seen after treatment, but the scores regarding sexual relationship were still affected after one year. Although sexual interest was reported to be low this finding highlights the need of support to these patients regarding sexuality during follow-up care. Furthermore, body image was more affected in women than in men indicating that interventions should be adjusted for sex. This was a small study and future studies with larger sample are needed.

Differentiation and survival influences of growth factors in human neuroblastoma

- Human neuroblastoma cell lines are established from high-stage, highly malignant tumours. Despite this and the fact that these tumours are arrested at an early, immature stage, many cell lines have the capacity to undergo neuronal differentiation under proper growth conditions. One such cell line is the noradrenergic SH-SY5Y cell line. These cells can be induced to mature by a variety of modalities, resulting in different mature phenotypes. The use of this cell system as a model to study the stem cell character of neuroblastoma is reviewed and discussed. In particular, we focus on growth factor dependencies in the SH-SY5Y system, and compare that to the normal situation, i.e. growth factor control of sympathetic neuronal and neuroendocrine differentiation during human and rat embryogenesis.
