- Colorectal cancer is the third most common cancer worldwide and the second most common cancer in Europe. Cumulative relative survival curves for both cancer of the colon and cancer of the rectum generally plateau after approximately 6-8 years. When this occurs, "population" or "statistical" cure is reached. We analyzed data from the Finnish Cancer Registry over a 50-year period using methods that simultaneously estimate the proportion of patients cured of disease (the cure fraction) and the survival time distribution of the "uncured" group. Our primary aim was to investigate temporal trends in the cure fraction and median survival of the uncured by age group for both cancer of the colon and rectum. For both cancers, the cure fraction has increased dramatically over time for all age groups. However, the difference in the cure fraction between age groups has reduced over time, particularly for cancer of the colon. Median survival in the uncured has also increased over time in all age groups but there still remains an inverse relationship between age and median survival, with shorter median survival with increasing age. The reasons for these impressive increases in patient survival are complex, but are highly likely to be strongly related to many improvements in cancer care over this same time period.

- Background: Epithelial ovarian cancer is associated with reproductive factors, but we lack knowledge if hormonal factors during pregnancy influence the mother's risk. Because pregnancy hormones are primarily produced by the placenta, placental weight may be an indirect marker of hormone exposure during pregnancy. Methods: In a nationwide Swedish cohort study, we included women with singleton births from 1982 to 1989. Women were followed for occurrence of invasive epithelial ovarian cancer, death, or emigration through 2004. Hazard ratios (HR) with 95% confidence intervals (95% CI) from Cox models were used to estimate associations between pregnancy exposures and epithelial ovarian cancer. Results: Among 395,171 women with information on placental weight in their first recorded birth, 316 women developed invasive epithelial ovarian cancer. Mean age at diagnosis was 44 years. Compared with women with a placental weight of 500 to 699 g, women with a high (>= 700 g) placental weight had an increased risk of developing epithelial ovarian cancer (HR, 1.47, 95% CI, 1.14-1.90). Compared with women with term pregnancies (40-41 weeks), women with post-term (>= 42 weeks) pregnancies had an increased risk of developing epithelial ovarian cancer (HR, 1.48, 95% CI, 1.00-2.19). These associations were slightly stronger when we included information about women's overall first birth, and slightly weaker when we included information about last recorded birth or ever last birth from 1982 to 1989. Conclusions: Because pregnancy hormone levels increase with placental weight, our study supports the hypothesis that hormone exposures during pregnancy influence the risk of invasive epithelial ovarian cancer among young women.

- BACKGROUND: Several reports have shown that less aggressive patterns of diagnostic activity and care are provided to elderly breast carcinoma patients. We sought to investigate whether differences in the management of older women with breast cancer are associated with survival. METHODS AND FINDINGS: In an observational study using a population-based clinical breast cancer register of one health-care region in Sweden, we identified 9,059 women aged 50-84 y diagnosed with primary breast cancer between 1992 and 2002. The 5-y relative survival ratio was estimated for patients classified by age group, diagnostic activity, tumor characteristics, and treatment. The 5-y relative survival for breast cancer patients was lower (up to 13%) in women 70-84 y of age compared to women aged 50-69 y, and the difference was most pronounced in stage IIB-III and in the unstaged. Significant differences in disease management were found, as older women had larger tumors, had fewer nodes examined, and did not receive treatment by radiotherapy or by chemotherapy as often as the younger women. Adjustment for diagnostic activity, tumor characteristics, and treatment diminished the relative excess mortality in stages III and in the unstaged, whereas the excess mortality was only marginally affected in stage IIB. CONCLUSIONS: Less diagnostic activity, less aggressive treatment, and later diagnosis in older women are associated with poorer survival. The large differences in treatment of older women are difficult to explain by co-morbidity alone.

- PURPOSE: Despite a uniform regional breast cancer care program, breast cancer survival differs within regions. We therefore examined breast cancer survival in relation to differences in diagnostic activity, tumor characteristics, and treatment in seven Swedish counties within a single health care region. METHODS: We conducted a population-based observational study using a clinical breast cancer register in one Swedish health care region. Eligible women (n = 7,656) ages 40 to 69 years diagnosed with primary breast cancer between 1992 and 2002 were followed up until 2003. The 7-year relative survival ratio was used to estimate breast cancer survival. Excess mortality was modeled using Poisson regression to study differences in survival between counties. RESULTS: The 7-year relative survival for breast cancer patients was significantly lower (up to 7% in absolute risk difference) in one county (county A) compared with the others. This difference existed only among women diagnosed before 1998, ages 50 to 59 years, and was strongest among stage II breast cancer patients. Adjustment for amount of diagnostic activity eliminated the survival differences among the counties. The amount of diagnostic activity was also lower in county A during the same time period. After county A, during 1997-1998, began to adhere strictly to the regional breast cancer care program, neither any survival differences nor diagnostic activity differences were observed. INTERPRETATIONS: Markers of diagnostic activity explained survival differences within our region, and the underlying mechanisms may be several. Low diagnostic activity may entail later diagnosis or inadequate characterization of the tumor and thereby missed treatment opportunities. Strengthening of multidisciplinary management of breast cancer can improve survival.

- BACKGROUND: There are limited data on survival patterns among patients with monoclonal gammopathy of undetermined significance. DESIGN AND METHODS: We compared the survival of 4,259 patients with monoclonal gammopathy of undetermined significance, collected from hematology outpatient units in Sweden, with the survival of the general population by computing relative survival ratios. We also compared causes of death in these patients with those in 16,151 matched controls. RESULTS: One-, 5-, 10-, and 15-year relative survival ratios were 0.98 (95% CI 0.97-0.99), 0.93 (0.91-0.95), 0.82 (0.79-0.84), and 0.70 (0.64-0.76), respectively. Younger age at diagnosis of the gammopathy was associated with a significantly lower excess mortality compared to that in older patients (p<0.001). The excess mortality among patients with gammopathy increased with longer follow-up (p<0.0001). IgM (versus IgG/A) gammopathy was associated with a superior survival (p=0.038). Patients with monoclonal gammopathy of undetermined significance had an increased risk of dying from multiple myeloma (hazards ratio (HR)=553; 95% CI 77-3946), Waldenström's macroglobulinemia (HR=infinity), other lymphoproliferative malignancies (6.5; 2.8-15.1), other hematologic malignancies (22.9; 8.9-58.7), amyloidosis (HR=infinity), bacterial infections (3.4; 1.7-6.7), ischemic heart disease (1.3; 1.1-1.4), other heart disorders (1.5; 1.2-1.8), other hematologic conditions (6.9; 2.7-18), liver (2.1; 1.1-4.2), and renal diseases (3.2; 2.0-4.9). CONCLUSIONS: Our finding of decreased life expectancy in patients with monoclonal gammopathy of undetermined significance, which was most pronounced in the elderly and explained by both malignant transformation and non-malignant causes, is of importance in the understanding and clinical management of this disease. The underlying mechanisms may be causally related to the gammopathy, but may also be explained by underlying disease that led to the detection of the hematologic disease. Our results are of importance since they give a true estimation of survival in patients with monoclonal gammopathy of undetermined significance diagnosed in clinical practice.

- Objectives: to investigate long-term outcomes of mothers who have or have not held their stillborn baby, and predictors of having held the baby. Design: postal questionnaires. Setting: a nation-wide cohort study of mothers who gave birth to a singleton stillborn baby in Sweden in 1991. Participants: 314 out of 380 women answered the questionnaire and 309 reported whether or not they had held their baby. Measurements: scales measuring anxiety, depression and well-being. Findings: 126 (68%) mothers of 185 babies stillborn after 37 gestational weeks had held their baby and 82 (68%) mothers of 120 babies stillborn at gestational weeks 28-37 had also done so. Compared with mothers who agreed completely with the statement that staff gave enough support to hold the baby, mothers who did not agree were less likely to have held their baby [relative risk (RR) 4.1; 95% confidence interval (CI) 2.7-6.1], and mothers with a low level of education were less Likely to have held their baby than mothers with a higher level of education (RR 2.2; 95% CI 1.3-3.8). Mothers who had not held their babies born after 37 gestational weeks had an increased risk of headache (RR 4.3; 95% CI 1.1-16.5), and they were less satisfied with their steep (RR 2.7; 95% CI 1.5-5.0). The increased risk of long-term outcomes associated with not holding, compared with holding, a stillborn baby were Less pronounced for women who gave birth at gestational week 28-37 compared with women who gave birth after 37 gestational weeks. Key conclusions: in this cohort, we found an overall beneficial effect of having held a stillborn baby born after 37 gestational weeks, whereas findings for having held a stillborn baby born at gestational weeks 28-37 are uncertain. The attitude of staff influenced whether or not the mother held her stillborn baby. Implications for practice: if the mother is guided by staff in a sensitive way to hold her stillborn term baby, the experience wit( possibly be beneficial for her in the long term.

- Objective. To study how social support is associated with ensuing maternal depression following stillbirth. Design. Data from a population-based national postal questionnaire. Setting. Sweden. Population. A total of 314 (83%) of all 380 Swedish-speaking women who gave birth to singleton stillborn infants in Sweden during 1991, identified through the Swedish Medical Birth Register. Methods. Postal questionnaires addressing maternal social support and demographics were completed three years following the stillbirth. The association between support-related factors and later maternal depression was assessed using multivariable regression models. Main outcome measure. The Center for Epidemiologic Studies Depression Scale. Results. In adjusted analyses, a father’s refusal to talk about a stillborn baby with the mother was associated with an almost five-fold risk of later maternal depressive symptoms [adjusted risk ratio (RR) 4.6, 95% confidence interval (CI) 1.5–14.5]. The mother's belief that she could talk with the infant's father about the child was associated with a reduced risk (adjusted RR 0.5, 95% CI 0.1–0.9). Conclusions. Unwillingness of the father to discuss a stillborn infant with the mother was related to subsequent maternal depressive symptomatology.
