Recent insights into trends of thyroid cancer incidence in Lithuanian population exposed to Chernobyl fallout early in life.

In the last three decades, an increase in thyroid cancer incidence has been observed worldwide, as well as in Lithuania. Although the rise was linked to overdiagnosis, the role of lifestyle and environmental factors, including exposure to ionizing radiation, cannot be excluded. In our retrospective study, we aimed to assess the association between the average age-specific thyroid dose due to the radioactive iodine uptake during childhood and adolescence from the Chernobyl fallout in Lithuania, and the trends of incidence of thyroid cancer from 1991 to 2015 in different regions. Averaged age-dependent thyroid doses were estimated for every municipality based on radioiodine activity in milk, reconstructed from available 131I activity measurements in the grass. Thyroid cancer incidence rates were calculated for the entire population and for two age at the time of exposure groups: 0-19 years and 0-9 years. Thyroid cancer relative risk (RR) was estimated for three municipality-specific thyroid dose (for 0-year-old babies) categories: less than 100 mGy (reference group), 100-199 mGy, and ≥200 mGy. Over the study period (1991-2015), a total of 5664 cases of thyroid cancer were registered in the entire Lithuanian population; 817 cases in the age group from 0 to 19 years at the time of the Chernobyl accident, and 266 cases in the age group from 0 to 9 years. Age-standardized thyroid cancer incidence rates have notably increased since 2000, peaked in 2009 (especially in females), and then slightly decreased and stabilized. The estimated average municipality-specific age-dependent thyroid doses ranged from 270 mGy in western Lithuania to 1.5 mGy in central and northern Lithuania. For the age group of 0-19 years at the time of the accident, in the period 1991-1995, the thyroid cancer relative risk was significantly increased (RR 3.91; 95 % CI: 1.27-10.29, p=0.01) in the highest dose category, compared to the lowest (although based on a small number of cases). For the age group 0-9 years at the time of the accident, a tendency of increased RR in the highest dose category appeared in the most recent period, 2011-2015. Our observations need to be confirmed by further following trends of thyroid cancer incidence in the cohort of 0-19-year-old Lithuanians at the time of the Chernobyl accident.

Incidence, Mortality, and Survival Trends in Cancer of the Gallbladder and Extrahepatic Bile Ducts in Lithuania.

Background and Objectives: Gallbladder cancer is a rare type of cancer, with aggressive clinical behavior. Limited treatment options provide poor survival prognosis. We aimed to investigate the incidence, mortality trends, and survival of gallbladder and extrahepatic bile duct cancer in Lithuania between 1998 and 2017. Materials and Methods: The study was based on the Lithuanian Cancer Registry database. The study included all cases of cancer of the gallbladder and extrahepatic bile ducts reported to the Registry in the period 1998-2017. Age-specific and age-standardized incidence rates were calculated. In addition, 95% confidence intervals for APC (Annual Percent Change) were calculated. Changes were considered statistically significant if p was <0.05. Relative survival estimates were calculated using period analysis according to the Ederer II method. Results: Age-standardized rates for gallbladder cancer and extrahepatic bile duct cancer among females decreased from 3.91 to 1.93 cases per 100.000 individuals between 1998 and 2017, and from 2.32 to 1.59 cases per 100.000 individuals between 1998 and 2017 among males. The highest incidence rates were found in the 85+ group with 27.5/100,000 individuals in females and 26.8/100,000 individuals in males. The 1-year as well as 5-year relative survival rates of both genders were 34.29% (95% CI 32.12-36.48) and 16.29% (95% CI 14.40-18.27), respectively. Conclusions: Incidence and mortality from gallbladder and extrahepatic bile duct cancer decreased in both sexes in Lithuania. Incidence and mortality rates were higher in females than in males. Relative 1-year and 5-year survival rates showed a steady increase during the study period among males and females.

Androgen-deprivation therapy and risk of death from cardio-vascular disease in prostate cancer patients: a nationwide lithuanian population-based cohort study.

Purpose: The main purpose of this study was to evaluate the risk of CVD mortality in the national cohort of patients diagnosed with prostate cancer and treated with ADT compared with the ADT non-users.Materials and methods: We performed a retrospective cohort study of patients aged 40-79 years and diagnosed with prostate cancer between 1 January 2012 and 31 December 2016 using the Lithuanian Cancer registry data. In total, 13 343 prostate cancer patients were included in the final study cohort who exclusively used gonadotropin-releasing hormone agonists. The primary outcomes that were registered during the follow-up of this study were overall CVD death.Results: There was a higher risk of CVD death in the cohort of patients treated with ADT than in ADT non-users (HR 2.14, 95% CI [1.86-2.45], p < 0.001). Moreover, there was an increased risk of death from ischemic heart disease and stroke (HR 1.42, 95% CI [1.16-1.73] and 1.70, 95% CI [1.18-2.45], respectively) among ADT users. Finally, the risk of CVD-related mortality was highest in the 70-79 age group of ADT users (HR 4.78, 95% CI [3.79-6.04]).Conclusions: This study shows that ADT usage is associated with increased CVD-related mortality risk for patients diagnosed with prostate cancer compared with ADT non-users. The highest mortality risk was found for ischemic heart disease and stroke. CVD-related mortality was increased in the elder group of patients also.

Malignant mesothelioma of the tunica vaginalis testis: a rare case and review of literature.

BACKGROUND: Malignant mesothelioma of the tunica vaginalis is a rare tumour which comprises less than 1% of all mesotheliomas. CASE PRESENTATION: 69-years old patient with painful hard mass and hydrocele in the right scrotum to whom a right hydrocelectomy was performed. Any history of scrotal trauma or exposure to asbestos was not present. Excisional biopsy revealed a multinodular tumour with focal areas of necrosis and infiltrative growth. According to morphological and immunohistochemical findings, diagnosis of malignant biphasic mesothelioma of the tunica vaginalis testis was made. Two months after hydrocelectomy, right inguinal orchidectomy was performed. Post-surgical whole body CT scan revealed paraaortic and pararenal lymphadenopathy, likely to be metastatic. Adjuvant treatment with 6 cycles of cisplatin and pemetrexed was applied. After 3 cycles of chemotherapy, CT scan showed progression and the treatment was changed to gemcitabine 1 month after. CONCLUSIONS: Although malignant mesothelioma of the tunica vaginalis is a rare malignancy, it poses a diagnostic challenge which can mimic common inguinal or scrotal diseases such as hydrocele. Despite aggressive surgical procedures or adjuvant therapies, the prognosis remains poor.

Reduced risk of prostate cancer in a cohort of Lithuanian diabetes mellitus patients.

BACKGROUND: During the past decade, a huge interest was devoted to the type-2 diabetes mellitus and their associations with prostate cancer development. OBJECTIVES: The aim of this study was to determine whether type 2 diabetes mellitus and treatment with metformin is associated with prostate cancer risk. MATERIALS AND METHODS: The cohort was composed of diabetic male patients identified in the National Health Insurance Fund database during 2000-2016 and cancer cases in national Cancer Registry. We calculated standardized incidence ratios (SIR) for prostate cancers as a ratio of observed number of cancer case in people with diagnosis of diabetes to the expected number of cancer cases in the underlying general population. RESULTS: 2754 prostate cancers were observed versus 3111.26 expected within the period of observation entailing an SIR of 0.89 (95% CI: 0.85-0.92). Significantly lower risk of prostate cancer was found in diabetes patients in all age groups, also was in metformin-users and never-users' groups, with higher risk reduction in metformin-users (SIR 0.71, 95% CI: 0.68-0.75) than in diabetes patients never-users (SIR 0.88, 95% CI: 0.80-0.96). CONCLUSION: In this large population-based study, we found a significantly decreased risk of prostate cancer among men with diabetes and metformin-users.

Increased kidney cancer risk in diabetes mellitus patients: a population-based cohort study in Lithuania.

BACKGROUND: Diabetes is associated with increased risk of various cancers but its association with kidney cancer is unclear. The objective of this study was to evaluate the association between T2DM with or without metformin use and the risk of kidney cancer in a population-based national cohort in Lithuania. METHODS: The cohort was composed of diabetic patients identified in the NHIF database during 2000-2012. Cancer cases were identified by record linkage with the national Cancer Registry. Standardized incidence ratios (SIRs) for kidney cancer as a ratio of observed number of cancer cases in diabetic patients to the expected number of cancer cases in the underlying general population were calculated. RESULTS: T2DM patients (11,592) between 2000 and 2012 were identified. Overall, 598 cases of primary kidney cancer were identified versus 393.95 expected yielding an overall SIR of 1.52 (95% CI: 1.40-1.64). Significantly higher risk was found in males and females. Significantly higher risk of kidney cancer was also found in both metformin users and never-users' groups (SIRs 1.45, 95% CI: 1.33-1.60 and 1.78 95% CI: 1.50-2.12, respectively). CONCLUSIONS: The patients with T2DM have higher risk for kidney cancer compared with the general Lithuanian population.

Trends in Breast Cancer Incidence and Stage Distribution Before and During the Introduction of the Mammography Screening Program in Lithuania.

BACKGROUND:: The aim of this study was to analyze the incidence trends of localized and advanced breast cancer (BC) before and during the implementation of the mammography screening program (MSP) in Lithuania. METHODS:: The study period was divided into 2 intervals: the prescreening period (1998-2005) and implementation period (2006-2012). Analysis was performed for 3 age-groups: 0 to 49 years, 50 to 69 (target population), and older than 70. RESULTS:: In all age-groups, the incidence of localized BC has shown a steady increase, while the incidence of advanced stage BC has decreased. In the target population, during the study period, the stage I BC incidence increased statistically significantly by 10.3% per year (from 3.3 per 100 000 in 1998 to 12.2 per 100 000 in 2012). The increase in localized BC was faster in the period before the implementation of the MSP than during the implementation in 2006 to 2012 (10.3% and 5.7%). A slightly statistically significant decrease was observed for advanced BC during the study period (-1.1% per year), while during the implementation of the MSP, significant changes were not seen. CONCLUSIONS:: The results of our study indicate that the implementation of the MSP in Lithuania did not significantly influence trends of localized and advanced BC. Changes observed during the study period, including the prescreening and screening introduction periods, may reflect the general trends in the awareness of BC and improvements in diagnostics.

Lung Cancer Survival in Lithuania: Changes by Histology, Age, and Sex From 2003-2007 to 2008-2012.

Lung cancer is the most common cancer-related death worldwide. The aim of this study is to describe the most recent survival rates by sex, age group, extent of disease, and histology of lung cancer in Lithuania. The study is based on the Lithuanian Cancer Registry database. The analysis included patients with primary invasive lung cancer diagnosed in 1998 to 2012 (International Classification of Diseases, Tenth Revision C33 and C34). Patients were followed up with respect to vital status until December 31, 2012. Five-year relative survival estimates were calculated using period analysis. Relative survival was calculated as the ratio of the observed survival of patients with cancer and the expected survival of the underlying general population. In our study, the overall 5-year relative survival was low but increased slightly (10.7%) from 2003-2007 to 2008-2012. Positive changes in survival were evident in both sexes, in almost all age groups and for all histological groups and disease stages. Adenocarcinoma relative survival increased from 6.7% in 2003-2007 to 12.8% in 2008-2012 and squamous cell carcinoma increased from 7.4% in 2003-2007 to 11.1% in 2008-2012. Patients with small-cell carcinoma had the worst survival (2.9% in 2003-2007 and 3.6% in 2008-2012). The majority of patients with lung cancer are diagnosed with advanced disease. The number of new cases of advanced lung cancer increased from 35.1% to 37.8%. Despite low overall survival, there were positive changes in survival in both sexes, in almost all age groups, and for all histological groups and disease stages. The survival rate of patients with lung cancer in Lithuania is similar to that in other European countries.

Breast Cancer Screening Program in Lithuania: Interval Cancers and Program Sensitivity After 7 Years of Mammography Screening.

OBJECTIVE: Analysis of interval cancers is critical in determining the sensitivity of screening and represents an objective measure of the quality of mammography screening program (MSP). METHODS: Period analyzed: from 2006 to 2012. The rate of screen-detected, interval cancers and program sensitivity were measured. A comparison of screen-detected and interval cancers was performed. RESULTS: During the period of the study, 429 473 women were screened and 1297 were found to have cancer. The overall screen-detected cancer rate was 30.2 per 10 000 women screened. Four hundred thirty-one case of interval cancers have occurred during the period of the study. The interval cancer ratio (ICR) was 0.25. Overall sensitivity of MSP amounted to 75.1%. Slightly lower sensitivity was found among the youngest age-group, especially for those with lobular cancers. Interval cancers were bigger in size, more often with metastases in lymph nodes, than screen-detected cancers, but these differences were not statistically significant. CONCLUSIONS: Overall program sensitivity in Lithuania is about 75%, ICR is 0.25, and these parameters are comparable to other European countries.

Suicide risk among colorectal cancer patients in Lithuania.

PURPOSE: We aimed to estimate suicide risk among colorectal cancer patients in the country showing the highest suicide rates among developed countries. METHODS: Patients with colorectal cancer diagnosed between 1998 and 2012 were identified from the Lithuanian Cancer Registry. Standardised mortality ratios (SMRs) for suicide were calculated for patients diagnosed with cancer in Lithuania, relative to suicide rates in the general population. RESULTS: Twenty thousand seven hundred sixty-five primary colorectal cancer cases diagnosed between 1998 and 2012 were extracted from the database. Among 19,409 first primary colorectal cancer patients, we identified 67 suicides and the expected number of suicides calculated from general population was 41.4 in this cohort, resulting in an SMR of 1.62 for both sexes (95% CI, 1.27-2.06). A higher suicide risk was found for women (SMR 2.15; 95% CI 1.35-3.41), than for men (SMR 1.48; 95% CI 1.12-1.96). The suicide risk was almost twice higher in patients 60 and older, with highest increase in the oldest patients (SMR 2.12, 95% CI 1.01-4.46). The risk of suicide was not significantly elevated in colorectal cancer patients with localised tumours, but there was a fourfold increase in risk in patients with stage IV tumours. Compared with the general population, the risk of suicide among colorectal cancer patients was four times higher during the first 3 months after diagnosis and decreased thereafter. CONCLUSIONS: The patients with colorectal cancer have a higher rate of suicide compared with the general Lithuanian population. Sex, age, advanced rectal cancer and distant spread of disease were the main predictors of suicide among colorectal cancer patients.

A Population-Based Analysis of Incidence, Mortality, and Survival in Testicular Cancer Patients in Lithuania.

Background and objectives: The aim of this study was to analyze trends in testicular cancer incidence, mortality, and survival in Lithuania during the period 1998-2013. Materials and Methods: The study was based on all cases of testicular cancer reported to the Lithuanian Cancer Registry between 1998 and 2013. Age group-specific rates and standardized rates were calculated using the direct method (European standard population). The Joinpoint regression model was used to provide the annual percentage change (APC). Five-year relative survival estimates were calculated using period analysis. Relative survival was calculated as the ratio of the observed survival of cancer patients and the expected survival of the underlying general population. Results: During the study period, the age-standardized incidence rate of testicular cancer increased from 1.97 to 3.45 per 100,000, with APC of 2.97% (95% CI 0.9 to 5.1). Incidence rate of seminomas changed from 0.71 to 1.54 per 100,000, with APC of 2.61% (95% CI -0.4 to 5.7), and the incidence rate of non-seminomas increased from 0.84 to 1.83 per 100,000, with APC of 4.16% (95% CI 1.6 to 6.8). The mortality rate of testicular cancer in Lithuania during this period declined from 0.78 to 0.51 per 100,000, with APC of -2.91% (95% CI -5.5 to -0.3). Relative five-year survival ratio for the period 2009-2013 was 89.39% (95% CI 82.2 to 94.4). In our study, the overall five-year relative survival increased slightly (10.1%) from 2004-2008 to 2009-2013 (from 79.3% to 89.4%). Conclusions: A moderate increase of testicular cancer incidence has been observed in Lithuania between the years 1998 and 2013, while the mortality rate decreased. The five-year relative survival increased according to different period estimates; however, the results could have been higher if a multidisciplinary approach to diagnostics and management in the concerned centers had been implemented in Lithuania as in other countries.

Improved perioperative care is associated with improved long-term survival in colorectal cancer.

PURPOSE: To compare perioperative colorectal cancer care and survival in patient cohorts operated in 2005 and in 2010 in Lithuania. METHODS: Comparative observational cohort study was performed. The study was conducted in the three Lithuanian cancer hospitals. Patients, who underwent curative surgery for colorectal cancer in 2005 and 2010, were included. Demographic characteristics, distribution of the tumors, preoperative diagnostics and staging, surgical treatment, the quality of pathological examination, morbidity, and mortality were analyzed. One- and 5-year overall survival data were compared between the groups. RESULTS: Colorectal cancer diagnostics and treatment improved from 2005 to 2010 significantly. The disease was identified as stage III-IV for 45 vs. 48% of the patients; however, computed tomography staging scan was performed only for 5.9 vs. 17.8% in 2005 and 2010, respectively. Laparoscopic operations were performed 1.5 vs. 10.5% and abdominoperineal resections-42.7 vs. 31.7% in 2005 and 2010, respectively. The number of harvested lymph nodes was mentioned in 55.8 vs. 97.7% of the cases, whereas more than 12 lymph nodes were examined in 18 vs. 66.6% of cases after histological examination. The overall 5-year survival was 52.1 vs. 63.1% (p < 0.0001), while the 5-year survival of the patients with stage IV of disease was 4.2 vs. 17.8% in 2005 and 2010, respectively. CONCLUSION: Preoperative investigation, surgical treatment, pathological examination, and postoperative course are associated with improved overall survival in colorectal cancer patients, undergoing curative surgery in the resource-limited settings.

Education predicts cervical cancer survival: a Lithuanian cohort study.

Background: : We examined inequalities in cervical cancer survival in Lithuania by education and place of residence. : The study is based on the linked dataset that includes all records of the 2001 population Census, all records from Lithuanian Cancer Registry (cancer incidence) and all death and emigration records from Statistics Lithuania for the period between 6 April 2001 and 31 December 2009. The study group includes cervical cancers registered in the Cancer Registry from 1 January 2002 to 31 December 2006. Analysis was restricted to women who were 25-64 years old at the Census date (in total 1 866 cases). : During the study period there were 671 deaths corresponding to an overall 5-year survival proportion 64.13% (95% CI 61.86-66.31). Place of residence and education of cervical cancer patients had strong impact on survival; 5-year survival was higher in women living in urban areas than in rural (68.61 and 55.93%) and survival decreased with decreasing education: from 79.77% in highest education group to 64.85 and 50.48% in groups with secondary and lower than secondary education. The effect of place of residence declined when stage of disease was included in the model and became not significant in final model with education adjustment. The effect of education declined after inclusion of stage and other variables, however, remained significant. : We found that women with higher education experienced higher survival following a cervical cancer diagnosis, and stage of disease at the time of diagnosis explains only the part of observed differences.

Education, survival, and avoidable deaths in Lithuanian cancer patients, 2001-2009.

Background Our aim in this study is to provide a systematic assessment of the site-specific cancer survival rates of patients with different educational levels, using population-based census-linked registry data covering the entire population of Lithuania. Material and methods The study is based on the linkage between all records of the 2001 population census and all records from Lithuanian Cancer Registry (cancer incidence) and Statistics Lithuania (deaths) for the period between 6 April 2001 and 31 December 2009. Results For the vast majority of cancer sites we found an inverse gradient in survival, with the worst survival indicators in the lowest educational group. We estimated that 18.6% of the deaths in Lithuanian cancer patients could have potentially been postponed, if all the patients had the same cancer mortality as the patients with the highest educational level. Conclusion Our findings offer a warning that although the survival rates of cancer patients are improving, this progress hides disparities between different groups of patients.

Preoperative Endoscopic Biliary Drainage May Negatively Impact Survival Following Pancreatoduodenectomy for Ampullary Cancer.

BACKGROUND/AIMS: Ampullary carcinoma is a rare tumour with a high resectability rate. There is an increasing body of evidence indicating not only tumour-related factors, but also jaundice influence survival following curative resection. Several modalities for preoperative biliary drainage are available; however, routine preoperative endoscopic biliary drainage (PEBD) is not recommended. There is no sufficient data regarding the impact of PEBD on long-term outcomes. The aim of our study was to identify predictive factors of survival with special regard to PEBD in patients undergoing curative resection for ampullary carcinoma. PATIENTS AND METHODS: Data from 64 consecutive patients with adenocarcinoma of the papilla of Vater who have been operated on was analysed. Overall survival was defined from the date of surgery to the date of death, or censored at the last patient contact. Survival analysis was determined by means of the Kaplan-Meier method. The significance of the demographic, clinical and histopathologic factors was ascertained by the log-rank test. A Cox proportional hazard model was used to determine independent prognostic factors of survival. RESULTS: Twenty patients (31.2%) underwent PEBD. Univariate analysis revealed tumour-related factors, age over 70, and PEBD to negatively influence survival. Five of them (excluding T stage) were identified as the independent prognosticators, while PEBD appeared to be the most decisive factor. Median survival for patients who underwent PEBD was 25.3 months as compared to 112.9 months for those who did not. In conclusion, PEBD negatively affected long-term outcomes in our patients with resected ampullary carcinoma.

Factors influencing survival after pancreatoduodenectomy for ductal adenocarcinoma depend on patients' age.

BACKGROUND: It is supposed that a prolonged lifetime will be associated with increased incidence of PDAC among the elderly. Some studies show a tendency toward decreased survival in the elderly patients following pancreatoduodenectomy for PDAC. The aim of this study was to evaluate factors, influencing survival following pancreatoduodenectomy for PDAC in different age groups. METHODS: Data of 251 patients after pancreatoduodenectomy for PDAC between 1999 and 2012 were analyzed. The Kaplan-Meier method and log-rank test were used to calculate survival and to compare differences between groups. The Cox proportional hazard model was applied to indentify independent prognosticators. RESULTS: The overall median survival was 14.9 months. Postoperative morbidity was 25.5% with a 5.1% mortality rate. No significant differences in the overall morbidity (22.4 vs. 29.6%) or mortality (2.8 vs. 8.3%) rates were observed between different patients' age groups (<70 years and >70 years). Multivariate analysis revealed R1 resection (HR 1.76) and poor tumor differentiation (G3-G4) (HR 1.48) were independent negative factors for survival in patients <70 years. Lymph-node metastases (N1) - HR 4.89 and perineural invasion - HR 2.73 were independent prognosticators in the elderly. CONCLUSIONS: Our study highlighted different factors influencing long-term survival after pancreatoduodenectomy: R1 resection and poor tumor differentiation (G3-G4) were independent negative factors for survival in patients <70 years, while perineural invasion and lymph-node metastases result in worse survival among the elderly.

Cancer survival in Lithuania after the restoration of independence: rapid improvements, but persisting major gaps.

BACKGROUND: Following restoration of political independence in 1990, Lithuania underwent rapid societal and economic changes. We aimed to assess trends in cancer survival in the first two decades following these changes. MATERIAL AND METHODS: We used population-based data from the Lithuanian Cancer Registry and period analysis techniques to examine trends in one-, 2-5- and five-year relative survival between 1995-1999 and 2005-2009 for 24 common cancers in Lithuania. RESULTS: Between 1995-1999 and 2005-2009, five-year relative survival increased significantly for 20 of 24 cancers, and for 10 cancers the increase exceeded 10% units. Five-year relative survival estimates reached 46%, 69% and 91% for colorectal, breast and prostate cancer in 2005-2009, respectively, while patients with testicular cancer, Hodgkin's or non-Hodgkin's lymphoma had a five-year relative survival of 77%, 75% and 50%, respectively. CONCLUSION: We found a rapid increase in survival for most forms of common cancers in Lithuania between 1995 and 2009. Nevertheless, several cancers with effective therapies exhibit considerable gaps compared with Northern and Western European countries. Despite ongoing rises in survival, mortality declines are not yet manifesting for important common cancers such as breast and colorectal cancer. Rapid incidence rises suggest that increases in survival for prostate and thyroid cancers are massively influenced by early detection-related effects. Improving the availability of effective therapies, and carefully planned early detection programs may help to increase cancer survival in Lithuania in the future.

Well-being of newly diagnosed women with breast cancer: which factors matter more?

BACKGROUND: The assessment of health-related quality of life (HRQL) in newly diagnosed breast cancer patients is necessary to address predictive factors in supportive clinical practice. PURPOSE: The objectives of this study are to evaluate self-reported HRQL within 1 year after breast cancer diagnosis and to determine important factors associated with self-reported impaired HRQL. METHODS: A cross-sectional study was performed in newly diagnosed breast cancer patients. The statistical analysis included descriptive statistics and stepwise logistic regression modeling. RESULTS: The survey response rate was 67 % (n = 338). Almost 50 % of the studied population was identified as experiencing anxiety. The impaired HRQL domains were emotional functioning and global health status. Severely expressed symptoms included insomnia, fatigue, and financial difficulties. Poor financial situation, comorbidities, unemployment, and lack of psychological counseling were identified as important predictive factors (p < 0.001). CONCLUSIONS: Psychosocial, but not clinical, factors were the prevalent predictive factors in impaired HRQL. Early identification of women that are at risk of poorer HRQL and interventions of psychosocial support following breast cancer diagnosis are recommended.
