Predicting hypertension among Korean cancer survivors: A nationwide population‐based study

Hypertension is the most common comorbidity among cancer survivors, although there is no model for predicting hypertension in this population. Therefore, we developed a model for predicting hypertension using data from 6,480 Korean cancer survivors who were ≥20 years old. The odds ratios (ORs) for hypertension were calculated using stepwise logistic regression analyses, and a nomogram was generated to predict hypertension. Hypertension was independently associated with an age of ≥65 years (OR: 3.058), male gender (OR: 1.195), obesity (OR: 1.998), prehypertension (OR: 2.06), dyslipidaemia (OR: 2.011) and diabetes mellitus (OR: 2.297). Each variable in the nomogram was assigned a specific number of points, and the total score (range: 0–400) was used to obtain a value for predicting hypertension. The estimated prevalence of hypertension increased when the total nomogram score exceeded the sixth decile (total points: 128; p for trend <.001). Therefore, among Korean cancer survivors, hypertension was significantly associated with an age of >65 years, male gender, obesity, and having various comorbidities (e.g., prehypertension, dyslipidaemia and diabetes mellitus). Furthermore, our nomogram could predict the incidence of hypertension, and the sixth decile of the total nomogram score predicted an increased risk of hypertension.     

Nutrition care of cancer patients—A survey among physicians and nurses

In order to quantify gaps in the provision of medical nutrition care in Germany and pinpoint specific areas of need, we collected data from patients, nurses and physicians. The results from the patient survey were published separately. A total of 506 participants from 69 certified centers answered the questions developed in cooperation with representatives from different professional groups (physicians, nurses and dietitians). Only about a third of participants reported that their institution provides structured pathways to nutritional counseling. 70.1% of those physicians reported that there was a specialist in nutrition available at their center while only 55.8% of nurses agreed. Only a quarter (24.2% and 26.9%) of physicians and nurses reported that their institution provided continuation of nutrition care after dismissal. A gap exists between need and consistent delivery of nutrition care services. Structured nutrition care pathways provided by legally certified nutrition professionals pathways are lacking. Cancer organizations may support this process by requiring documented nutrition care pathways and provision of services on a need based system into guidelines and certification criteria.     

Hospitalizations among children of survivors of childhood and adolescent cancer: a population-based cohort study

Curative but potentially mutagenic cancer therapy might lead to untoward disorders and increased hospitalization among the offspring of childhood cancer survivors. Hospitalizations in childhood were evaluated in a population-based cohort of 1,920 offspring of 3,963 childhood cancer survivors, 6,394 offspring of 5,657 siblings and 9,594 population-based comparisons. The Danish Cancer Registry, Central Population Register and National Hospital Register were used to identify study subjects and hospitalizations. The probability for children in the offspring cohorts of being hospitalized before a given age was estimated using the Kaplan-Meier method. Hospitalization rate ratios (HRRs) were calculated using a Cox proportional hazards model with population comparisons as referent. Little differences in hospitalization histories were seen among offspring in the 3 cohorts. HRRs of overall hospitalization was 1.05 (95% CI, 0.98-1.12) for offspring of survivors and 1.01 (95% CI, 0.97-1.05) for offspring of siblings, neither of which was significantly different from that of population comparisons. No significant associations were seen for most of the main diagnostic groups of diseases including infections and perinatal disorders. A 6-fold excess risk of hospitalization for malignant tumors in survivors' offspring, however, could largely be explained by hereditary cancer syndromes, and part of the 2-fold excess hospitalization for benign tumors might similarly be explained by an underlying genetic susceptibility or by increased surveillance of children born to survivors. Assuming that hospitalization is an indicator of multifactorial genetic disease, the findings provide further reassurance that cancer therapies do not confer a high risk of such conditions in offspring born after treatments.     

Socioeconomic conditions among long‐term gynaecological cancer survivors—a population‐based case–control study

Background: The population of gynaecological cancer survivors is growing, yet little is known about the effects of cancer and treatment on socioeconomic conditions well beyond the completion of therapy. The aim of this study was to investigate the socioeconomic conditions in long‐term survivors of gynaecological cancer compared with a representative group of women from the general population. Material and methods: The study comprises women aged 32–75 residing in central part of Norway and who were treated as primary cases of gynaecological cancer at the University Hospital in Trondheim, Norway (n=160), and a control group from the general population (n=493). All analyses were done by χ² test and logistic regression. Results: Gynaecological cancer survivors scored lower on a Socioeconomic Condition Index than the control group. They had on the average a complete remission period of 12 years. Compared with the control group, they were more often disabled (p<0.01) and had lower annual household income (p<0.01). No difference was detected between the groups in ability to pay bills. More cases than controls had experienced problems assigning personal insurance (p<0.03). Conclusion: Long‐term gynaecological cancer survivors lived under poorer socioeconomic conditions, were more often disabled and had lower annual household income than the women in the control group, whereas no difference in ability to pay bills were found between the groups. In spite of poorer socioeconomic conditions, the gynaecological cancer survivors seem to adapt well to their financial situation. Copyright © 2009 John Wiley & Sons, Ltd.     

Risk factors for preterm delivery among early onset cancer survivors: A Finnish register-based study

Previous studies have shown an elevated risk for preterm delivery among early onset cancer survivors. Whether the preterm delivery starts spontaneously, due to possible uterine damage because of cancer treatment, or is induced due to maternal conditions is unclear. Our aim was to assess pregnancy related conditions in female cancer survivors possibly underlying the elevated risk for preterm labor. Nationwide cancer and birth registries were merged to identify 1,753 first deliveries of cancer survivors (diagnosed below 40 years of age) and 5,123 first deliveries of matched female comparison subjects between January 1991 and December 2013. Conditional logistic regression models were used to estimate the risk for pregnancy related conditions adjusting for maternal age, gestational age and smoking. We found an overall increased risk for hospitalization during pregnancy (OR 1.45, 95% CI 1.25–1.68), intrahepatic cholestasis (OR 2.86, 95% CI 1.09–7.49), fear of childbirth (OR 2.25, 95% CI 1.31–3.85) and mental disorders and diseases of the nervous system complicating pregnancy and labor (OR 5.89, 95% CI 2.31–15.00). Among survivors, 129 (7.4%) delivered preterm compared to 268 (5.2%) comparisons subjects (p = 0.004). We found a statistically significant increased risk for preterm delivery among cancer survivors with vaginal bleeding (OR 1.35, 95% CI 1.07–1.71) and pre-eclampsia (1.35, 95% CI 1.06–1.72) compared to comparison subjects with the same condition. Health professionals treating these women should be aware of these risks. In general, however, our results are reassuring when it comes to pregnancies among cancer survivors.     

Cardiovascular morbidity in long‐term survivors of early‐onset cancer: A population‐based study

Improvements in cancer therapy have resulted in an expanding population of early‐onset cancer survivors. In contrast to childhood and adolescent cancer survivors, there is still a lack of data concerning late morbidities among young adult (YA) cancer survivors. Thus, our aim was to investigate cardiac and vascular morbidity among early‐onset cancer survivors with a special interest in YA cancer survivors. In a population‐based setting, we explored the risk of cardiovascular disease in early‐onset cancer survivors compared to healthy siblings. Patients diagnosed with cancer below 35 years of age since 1975 were identified from the Finnish Cancer Registry, and 5‐year survivors were included in our study (N = 13,860). Information on cardiovascular morbidity was collected from the national hospital discharge registry. Compared to siblings, cancer survivors aged 0–19 and 20–34 at diagnosis had significantly elevated hazard ratios (HRs) for the studied outcomes: HR 13.5 (95% CI 8.9–20.4) and 3.6 (95% CI 2.8–4.6) for cardiomyopathy/cardiac insufficiency; HR 3.4 (95% CI 2.3–5.1) and 1.7 (95% CI 1.4–2.0) for atherosclerosis/brain vascular thrombosis; HR 3.3 (95% CI 1.7–6.5) and 1.8 (95% CI 1.5–2.1) for myocardial infarction/cardiac ischemia and HR 1.7 (95% CI 1.2–2.6) and 1.4 (95% CI 1.2–1.7) for cardiac arrhythmia. In both groups, depending on the outcome, the HR for adverse events was highest among lymphoma, brain tumor, leukemia and testicular malignancy survivors. Our results regarding late effects of childhood cancer survivors confirmed previous findings. Additionally, our study provides novel information concerning the YA cancer survivor population. Hence, our data may help in planning the risk‐based long‐term follow‐up of early‐onset cancer survivors.     

Mortality among offspring of women diagnosed with cancer: A population‐based cohort study

One in five cancers in women is diagnosed prior to and during a woman's fertile years. Our study evaluates mortality risks in offspring of mothers with history of cancer. From the Swedish Multi‐generation Register and the Cancer Register, we identified all 174,893 children whose mother had been diagnosed with cancer between 1958 and 2001. We categorized offspring into those born before (>1 year before), around (within 1 year before and after diagnosis) and after (>1 year after) their mother's cancer diagnosis and compared their risks of death (standardized mortality ratios, SMRs) and causes of death to the background population. Overall, offspring of mothers diagnosed with cancer had no increased mortality risk (SMR, 1.00; 95% confidence interval [CI], 0.97–1.03). Increased mortality risks were found in offspring of mothers with tobacco‐related cancers (head and neck, thoracic and cervical) (SMR, 1.23; 95% CI, 1.13–1.33), in children born around their mother's diagnosis (SMR, 1.66; 95% CI, 1.25–2.13) and in children born after their mother's hematopoietic cancer diagnosis (SMR, 2.07; 95% CI, 1.10–3.35). Compared to the background population, children born around their mother's diagnosis were more likely to die of congenital and perinatal conditions. Overall, offspring of women diagnosed with cancer were not at increased risk of death, except for certain subgroups. Timing of pregnancy in relation to diagnosis and cancer site modifies mortality risks in the offspring.     

Risk of subsequent gastrointestinal cancer among childhood cancer survivors: A systematic review

BackgroundChildhood cancer survivors (CCS) are at increased risk of developing subsequent malignant neoplasms, including gastrointestinal (GI) cancer. We performed a systematic review to summarize all available literature on the risk of, risk factors for, and outcome after subsequent GI cancer among CCS.MethodsA systematic search of the literature databases Medline/PubMed (1945–2014) and Embase (1947–2014) was performed to identify studies that consisted of ⩾1000 CCS and assessed incidence of or mortality from subsequent GI cancer as an outcome.ResultsA total of 45 studies were included. Studies that reported risk measures for subsequent GI cancer compared to the general population showed a 3.2 to 9.7-fold elevated risk in cohort studies including all childhood cancer types. Abdominal radiotherapy was associated with an increased risk of subsequent GI cancer in all four studies that assessed this risk. Survivors who had received procarbazine and platinum agents were also suggested to be at increased risk.ConclusionAbdominal radiotherapy is a risk factor for developing a subsequent GI cancer. Few studies examined detailed treatment-related risk factors and most studies had small number of GI cancer cases. Therefore, no conclusions could be drawn on the effect of time since childhood cancer on GI cancer risk and on outcome after a subsequent GI cancer. Additional research is necessary to further explore risk factors for and outcome after a subsequent GI cancer, and to systematically evaluate the harms and benefits of GI screening among high-risk survivors in order to give sound screening recommendations.     

Changes in the body image of bone sarcoma survivors following surgical treatment—A qualitative study

Background and Objectives

Among several long‐term effects, people treated for cancer may experience an altered appearance. Our study aims to identify how visible body changes following surgical treatment affect the life and identity of primary bone sarcoma survivors 3–10 years after diagnosis. A qualitative, phenomenological, and hermeneutic design was applied.

Methods

Sarcoma survivors (n = 18) who were previously treated at Norwegian Radium Hospital, Oslo University Hospital, participated in the study. In‐depth and semi‐structured interviews were conducted and analyzed using inductive thematic analysis.

Results

The main finding of this study concerned how altered appearance after bone cancer treatment in the hip/pelvis or lower extremities affected the participants’ self‐esteem. Half of the participants expressed concerns about their visible differences, particularly those with functional impairment. They felt that it is important to hide the bodily signs of changes to appear as normal as possible, as well as attractive and healthy. They describe, with specific examples, how these changes influence their self‐realization, especially their social life.

Conclusions

Healthcare providers who guide bone sarcoma survivors during follow‐up should develop a comprehensive understanding of what it means to cope with a changed and challenging body. J. Surg.

Preoperative hemoglobin count and prognosis of esophageal cancer,a population-based nationwide study in Finland

BackgroundThe prognostic value of preoperative hemoglobin in patients undergoing esophagectomy is unknown. The aim of this study was to examine whether preoperative hemoglobin is associated with prognosis in patients undergoing esophagectomy for cancer.Materials and methodsThis was a population-based nationwide retrospective cohort study in Finland, using Finnish National Esophago-Gastric Cancer Cohort (FINEGO). Esophagectomy patients with available preoperative hemoglobin measurement were included. Multivariable cox regression provided hazard ratios (HR) with 95% confidence intervals (CI), adjusted for calendar period of surgery, age at surgery, sex, comorbidity (Charlson Comorbidity Index), tumor histology, tumor stage, neoadjuvant therapy, type of surgery (minimally invasive or open) and annual hospital volume.ResultsOf the 1313 patients, 932 (71.0%) were men and 799 (60.9%) had esophageal adenocarcinoma. Overall all-cause mortality was significantly higher in the lowest hemoglobin count tertile (HR 1.26 (1.07–1.47)) compared to the highest tertile, but this association was attenuated after adjustment for confounding. No differences were found between the preoperative hemoglobin groups in the adjusted analyses of 90-day all-cause, 5-year all-cause, and 5-year cancer-specific mortality.ConclusionIn this population-based nationwide study, preoperative hemoglobin count had no independent prognostic significance in esophageal cancer.     

Preterm delivery among female survivors of childhood,adolescent and young adulthood cancer

We studied the deliveries of female cancer survivors and female siblings in a population‐based setting in Finland. Nationwide cancer and birth registries were merged to identify 1,309 first postdiagnosis deliveries of early‐onset (diagnosed under age 35) female patients with cancer and 5,916 first deliveries of female siblings occurring in 1987–2006. Multiple logistic regression models were used to estimate risk of preterm (<37 weeks), low birth weight (<2500 g) and small‐for‐gestational‐age deliveries. The risk of preterm delivery among cancer survivors compared with siblings was overall increased [odds ratio (OR) 1.46, 95% confidence interval (CI) 1.14–1.85], the increase in risk being visible in all diagnostic age groups. Risk of low birth weight (LBW) was also significantly increased (OR 1.68; 95% CI 1.29–2.18) but not after adjustment for duration of pregnancy (OR 1.11; 95% CI 0.76–1.64). Neither was the risk of small‐for‐gestational‐age (SGA) increased. The risk of preterm delivery was most pronounced in survivors delivering 10 years or more after diagnosis. Site‐specific analyses indicated that survivors of germ cell tumors and central nervous system (CNS) tumors were at increased risk of preterm delivery, although numbers were small. In childhood survivors, kidney tumors formed the main cause of preterm delivery. Pediatric, adolescent and young adult cancer survivors are at risk for preterm delivery. Heightened surveillance is recommended especially for Wilms', germ cell and CNS tumor survivors. Such adverse pregnancy outcomes can occur a decade or more after cancer diagnosis, indicating a continued need for obstetric awareness, surveillance and counseling in former patients with cancer.     

Cardiovascular medication after cancer at a young age in Finland: A nationwide registry linkage study

Despite improved survival rates, childhood and young adult (YA) cancer survivors face elevated risks for life‐threatening morbidities, especially cardiovascular complications. Our nationwide Finnish registry study investigated the purchases of cardiovascular medication from 1993 to 2011 in patients diagnosed with cancer aged below 35 years (N = 8,197) between 1993 and 2004 compared to siblings (N = 29,974) via linkage to the drug purchase registry. The cumulative incidence for purchasing cardiovascular medications was higher in childhood and YA cancer patients compared to siblings with a rising trend over time. After childhood cancer, the highest hazard ratio (HR) was found for purchasing anticoagulants (HR 19.8, 95% CI 8.5–45.9). The HRs for any cardiovascular medication (HR 7.2, 95% CI 5.1–10.1) and cardiac medication (HR 4.8, 95% CI 3.3–6.9) were markedly elevated after childhood cancer as well. Regarding YA cancer patients, the respective HRs were 2.5 (95% CI 2.0–3.2) for anticoagulants, HR 1.7 (95% CI 1.5–1.9) for any cardiovascular medication and HR 1.5 (95% CI 1.3–1.7) for cardiac medication. Among cancer patients, highest HRs for cardiovascular medication were observed after childhood acute lymphoblastic leukemia (ALL) and bone tumors (HR 10.2, 95% CI 6.8–15.5 and HR 7.4, 95% CI 4.0–13.7) and YA ALL and acute myeloid leukemia (HR 5.1, 95% CI 3.5–7.1 and HR 2.8, 95% CI 1.8–4.0). Our study demonstrated increased HRs for purchasing cardiovascular medication after early‐onset cancer compared to siblings reflecting elevated cardiovascular morbidity. Thus, the implementation of long‐term cardiovascular disease screening is imperative to prevent, detect and adequately treat cardiovascular late effects after cancer at a young age.     

Desire for children among male survivors of childhood cancer: A DCCSS LATER study

Background

Knowledge of the desire for children among childhood cancer survivors (CCSs) is scarce. This study evaluated the desire for children in male CCSs in comparison with male siblings.

Methods

A nationwide cohort study was conducted as part of the Dutch Childhood Cancer Survivor Study LATER study: 1317 male CCSs and 407 male sibling controls completed a questionnaire addressing the desire for children. Logistic regression analyses were used to explore the independent association between survivorship status and the desire for children. Furthermore, additional analyses were performed to identify which cancer-related factors were associated with the desire for children in male CCSs.

Results

After adjustments for the age at assessment, the percentage of men who had a desire for children was significantly lower among CCSs compared with the siblings (74% vs. 82%; odds ratio [OR], 0.61; 95% CI, 0.46–0.82; p = .001). The association between survivorship status and the desire for children was attenuated after adjustments for marital status, level of education, and employment status (OR, 0.83; 95% CI, 0.61–1.14; p = .250). The percentage of men who had an unfulfilled desire for children remained significantly higher among CCSs compared with the siblings after adjustments for sociodemographic factors (25% vs. 7%; OR, 5.14; 95% CI, 2.48–10.64; p < .001).

Conclusions

The majority of male CCSs have a desire for children. The likelihood of having to deal with an unfulfilled desire for children is 5 times higher among CCSs compared with their siblings. This insight is important for understanding the needs and experienced problems of CCSs regarding family planning and fertility issues.     

Social inequality in cancer survivors’ health behaviours—A Danish population‐based study

The aim of this study was to compare health behaviours (smoking, alcohol consumption, physical activity and diet), to explore social inequality in these behaviours among cancer survivors and individuals with no history of cancer, respectively, and to study the impact of time since diagnosis on cancer survivors’ health behaviours. Data from the Danish National Health Survey from 2013 were linked with data from the Danish Cancer Registry to identify all cancer diagnoses among the respondents during the period 1945–2012. In total, 11,166 cancer survivors and 151,117 individuals with no history of cancer were included. Cancer survivors smoked less and had a more sedentary lifestyle than individuals with no history of cancer. In relation to alcohol and dietary habits, no differences were found between the groups. Wide variations in health behaviours were seen across cancer sites, and in particular lung, bladder and oral cancer survivors had poor health behaviours. We found a clear social gradient in cancer survivors’ health behaviours which reveals the need for greater focus on socially differentiated initiatives within prevention and patient education for cancer survivors. Our study revealed rather blurred results in relation to identifying the optimal timing for health‐related behavioural interventions in cancer survivors.
