Paediatric dental outcomes among children exposed to chemotherapy in utero.

AIM: Our study prospectively evaluated dental development in children exposed to chemotherapy in utero compared with unexposed controls. DESIGN: Women who received chemotherapy while pregnant were enrolled in a research registry. After age two, each child's dentist was asked to complete a questionnaire about dental abnormalities and malformations, as well as for their unexposed siblings. Multivariate linear regression adjusting for age was used to compare the groups. RESULTS: Dental information was received for 67 exposed children and 59 controls. The majority of mothers were treated for breast cancer (79.1%) and primarily received doxorubicin (89.6%) and cyclophosphamide (80.6%). Mean gestational age at first exposure was 20.7 (±5.7) weeks. Mean age at dental evaluation was 8.0 (±4.3) years for exposed and 10.4 (±5.1) years for controls (P < .01). Missing teeth, tooth size, shape, and color did not differ significantly between groups. There was no statistical difference in dental caries, facial abnormalities, or abnormalities of enamel or gingiva. There was no association between any chemotherapy agent or regimen and increased risk of dental abnormalities. CONCLUSIONS: Overall, there was no difference in dental abnormalities between groups. These negative findings may be because no one received chemotherapy prior to 14 weeks when formation of primary teeth was beginning.

Impact of Survivorship Care on Young Adult Survivors of Childhood Cancer With Post-Traumatic Stress Symptoms.

OBJECTIVES: To assess post-traumatic stress symptoms (PTSSs) in young adult survivors of childhood cancer not receiving survivorship care and to determine whether attending a survivorship-focused healthcare visit was associated with changes in PTSSs. SAMPLE & SETTING: 44 young adult survivors from the Yale Cancer Center in Connecticut without prior survivorship clinic attendance. METHODS & VARIABLES: As part of a larger trial, participants were randomized to a model of survivorship-focused health care. The University of California at Los Angeles Post-Traumatic Stress Disorder (PTSD) Reaction Index assessed PTSS severity and frequency before and after the visit. RESULTS: At baseline, almost half of the participants were classified as partial PTSD likely or PTSD likely. Many met criteria for elevated levels of individual symptoms, particularly avoidance or numbing. At follow-up, PTSSs did not differ significantly from baseline. IMPLICATIONS FOR NURSING: Survivorship care should be encouraged by nurses in healthcare settings that do not specialize in caring for long-term survivors. Nurses should facilitate screening for PTSSs and promote interventions among survivors completing cancer therapy to help them transition to survivorship care.

Lymphedema in ovarian cancer survivors: Assessing diagnostic methods and the effects of physical activity.

BACKGROUND: Lymphedema is a poorly understood side effect of gynecologic cancer treatment. This study was designed to determine the prevalence of lower limb lymphedema (LLL) in a sample of ovarian cancer survivors via 3 different diagnostic methods and to assess the effect of a randomized exercise intervention. METHODS: Physically inactive ovarian cancer survivors (n = 95) were enrolled in a 6-month randomized trial of exercise (primarily brisk walking) versus attention control. LLL was measured at baseline and 6-month visits via a self-report questionnaire, optoelectronic perometry, and an evaluation by a certified lymphedema specialist. RESULTS: LLL prevalence ranged from 21% to 38% according to the diagnostic method, and there was substantial agreement between the self-report questionnaire and the lymphedema specialist evaluation (κ = 0.61). There was no agreement between the evaluation with optoelectronic perometry and the specialist evaluation. With LLL defined by any method, the baseline prevalence was 38% in both groups. At 6 months, both groups experienced a decreased LLL prevalence: 28% in the exercise group and 35% in the control group. There was no difference in the change in lymphedema prevalence between the 2 groups (P = .64). Body mass index was a significant predictor of LLL. CONCLUSIONS: With a potential prevalence of LLL as high as 40%, further evaluation of diagnostic methods is required to better characterize this side effect of ovarian cancer treatment. No adverse effect of exercise on LLL was found. Further research is strongly needed to evaluate predictors of LLL and the effects of exercise on LLL in order to develop effective physical activity recommendations for women with ovarian cancer.

Experiences with the survivorship care plan in primary care providers of childhood cancer survivors: a mixed methods approach.

PURPOSE: Focusing on primary care providers (PCPs) of known childhood cancer survivors, we used a mixed methods approach to understand providers' experiences with the survivorship care plan (SCP), as well as preferences and barriers regarding survivorship care. METHODS: The SCP was sent to 202 eligible PCPs of patients attending a regional survivorship clinic. The PCPs then completed quantitative postal surveys. Sixteen PCPs underwent an additional qualitative interview. Provider characteristics were examined as potential predictors of experiences, preferences, and barriers regarding survivorship care. Grounded theory was utilized to analyze the qualitative data. RESULTS: Respondents (n=134) included 55% pediatricians, 23% internists, 20% family practitioners, and 2% obstetricians/gynecologists. Only 8% of PCPs preferred to have primary responsibility for survivorship care; 46% favored a specialized clinic. A minority of PCPs reported that they felt "very comfortable" using the SCP to guide surveillance (31%) or deliver all survivorship care (3%). Endorsed barriers included lack of knowledge/training (74%), not recalling or understanding the contents of the SCP (69%), and uncertainty about who is responsible for providing care (58%). Two distinct themes emerged from the qualitative interviews: a preference not to be responsible for survivorship care, and uncertain utility of the SCP. CONCLUSIONS: Our study suggests that PCPs of childhood cancer survivors generally felt uncomfortable using the SCP and providing survivorship care. Even with the availability of the SCP, the biggest barrier was lack of knowledge. Our data suggests that including PCPs in survivorship care will require additional educational opportunities and evaluation of more collaborative models of care delivery.

Health Behaviors in Cervical Cancer Survivors and Associations with Quality of Life.

PURPOSE: Improvement in health behaviors following cancer diagnosis may contribute to better prognosis and well-being. This study examines the prevalence of health behaviors in cervical cancer survivors who have completed treatment, and associations between health behaviors and quality of life (QOL). METHODS: We recruited 204 women who had completed treatment for cervical cancer to participate in a randomized counseling intervention. Participants provided information on health behaviors (smoking, physical activity, and alcohol consumption); QOL (Functional Assessment of Cancer Therapy-Cervical questionnaire); and depression (Patient-Reported Outcomes Measurement Information System), anxiety (Patient-Reported Outcomes Measurement Information System), and distress (Brief Symptom Inventory) at baseline (9-30 months after diagnosis) and subsequent to the intervention. Data were analyzed using multivariate general linear models. FINDINGS: Participants ranged in age from 20 to 72 years at diagnosis (mean = 43 years), 41% were Hispanic, and 52% were non-Hispanic white. Three-fourths were stage 1 at diagnosis and 51% were treated with radiation with or without chemotherapy. At baseline, 15% of patients were current smokers, 4% reported alcohol consumption of >10 drinks per week, and 63% reported exercising <3 hours per week. Overall, 67.4% of cervical cancer survivors did not meet recommended national guidelines for at least 1 of these health behaviors. QOL scores were significantly higher for patients with greater physical activity (128 vs 118; P = 0.002) and increased with the number of recommended guidelines met (P for trend = 0.030). Associations between patient-reported outcomes and smoking and alcohol consumption did not reach statistical significance. Participants who met guidelines for all health behaviors also had less depression (P = 0.008), anxiety (P = 0.051), and distress (P = 0.142). Participants who improved their aggregate health behaviors during the 4-month follow-up experienced a greater improvement in QOL than those who did not improve their health behaviors (10.8 vs 4.5; P = 0.026). IMPLICATIONS: Results indicate that two-thirds of cervical cancer survivors are not meeting national guidelines for smoking, physical activity, and alcohol consumption following completion of definitive treatment. These adverse health behaviors were associated with impaired QOL and higher levels of depression and distress. Positive changes in health behaviors are associated with significant improvement in QOL.

Chemotherapy-only treatment effects on long-term neurocognitive functioning in childhood ALL survivors: a review and meta-analysis.

Therapy for childhood acute lymphoblastic leukemia (ALL) is associated with 5-year survival rates of ∼90% even after largely eliminating cranial radiation. This meta-analysis assesses the long-term neurocognitive functioning after chemotherapy-only regimens among survivors of childhood ALL. We conducted a systematic review to identify studies that evaluated long-term neurocognitive functioning following treatment of ALL by searching MEDLINE/PubMed, Database of Abstracts of Reviews of Effects, and secondary sources. Studies were included if ALL survivors were in continuous first remission, did not receive any radiation, were at least ≥2 years off therapy or ≥5 years since diagnosis, and were compared with a healthy control group. Weighted mean differences with 95% confidence intervals (CIs) were calculated. Ten nonexperimental studies met all eligibility criteria and included 509 patients and 555 controls. Meta-analysis demonstrated statistically significant moderate impairment across multiple neurocognitive domains evaluated, with intelligence most affected. Significant differences in standard deviation (SD) scores were found for Full Scale intelligence quotient (IQ) (-0.52 SD; 95% CI, -0.68 to -0.37), Verbal IQ (-0.54 SD; 95% CI, -0.69 to -0.40), and Performance IQ (-0.41 SD; 95% CI, -0.56 to -0.27); these SD scores correspond to changes in IQ of 6 to 8 points. Working memory, information processing speed, and fine motor domains were moderately, but statistically significantly, impaired. Meta-analysis of ALL survivors treated without cranial radiation demonstrated significant impairment in IQ and other neurocognitive domains. Patients and their families should be informed about these potential negative effects to encourage surveillance and educational planning. Both preventive and intervention strategies are needed.

A decision analysis to determine a testing threshold for computed tomographic angiography and D-dimer in the evaluation of aortic dissection.

OBJECTIVE: The objective of this study is to determine at what probability of thoracic aortic dissection (TAD) to use a computed tomographic angiography (CTA) or a d-dimer test. METHODS: We used decision analysis software to determine the testing threshold (TT) for 3 hypothetical decisions when evaluating for TAD: (1) no testing vs CTA, (2) no testing vs D-dimer, and (3) CTA vs D-dimer. One- and 2-way sensitivity analyses were performed to determine which variables were drivers of the TTs. RESULTS: We found TTs of 0.03%, 0.013%, and 0.6% for decisions 1, 2, and 3, respectively. For all 3 decisions, patient age and the annual rate of cancer were major drivers of the TT. In decisions 1 and 2, the probability of acute renal failure requiring renal replacement therapy was a major driver, whereas d-dimer sensitivity was a major driver for decision 3. CONCLUSION: The TTs for TAD are low and reflect the large mortality benefit from diagnosis and treatment when compared with the small risks of CTA. However, given the low prevalence of TAD (~0.05% among emergency department patients presenting with symptoms previously attributed to TAD), our results suggest that without high-risk features, clinicians should not order a CTA test for TAD. Depending on age, CTA should be considered for those patients with a disease probability greater than 0.3% to 2.1%, whereas d-dimer testing is appropriate in the range of pretest probabilities from 0.01% to 0.6%. Future studies should focus on clinical decision rules that place disease probabilities below, between, and above the calculated TTs.
