Pain and Fear of Cancer Recurrence in Survivors of Childhood Cancer

OBJECTIVES

Theoretical models suggest that anxiety, pain intensity, and pain catastrophizing are implicated in a cycle that leads to heightened fear of cancer recurrence (FCR). However, these relationships have not been empirically examined. The objective of this study was to examine the relationships between anxiety symptoms, pain intensity, pain catastrophizing, and FCR in childhood cancer survivors and their parents and to examine whether pain catastrophizing predicts increased FCR beyond anxiety symptoms and pain intensity.

METHODS

The participants were 54 survivors of various childhood cancers (Mage=13.1 y, range=8.4 to 17.9 y, 50% female) and their parents (94% mothers). Children reported on their pain intensity in the past 7 days. Children and parents separately completed measures of anxiety symptoms, pain catastrophizing, and FCR.

RESULTS

Higher anxiety symptoms were associated with increased pain intensity, pain catastrophizing, and FCR in childhood cancer survivors. Higher anxiety symptoms and pain catastrophizing, but not child pain intensity, were associated with FCR in parents. Hierarchical linear regression models revealed that pain catastrophizing explained unique variance in both parent (ΔR2=0.11, P<0.01) and child (ΔR2=0.07, P<0.05) FCR over and above the effects of their own anxiety symptoms and child pain.

DISCUSSION

The results of this study provides novel data on the association between pain and FCR and suggests that a catastrophic style of thinking about pain is more closely related to heightened FCR than one's anxiety symptoms or the sensory pain experience in both childhood cancer survivors and their parents. Pain catastrophizing may be a novel intervention target for survivors and parents struggling with fears of recurrence.

The implementation of fertility guidelines and impact on the rate of pre-therapy fertility risk discussions in pediatric oncology: A retrospective cohort study

e22027

Background: Pediatric cancer patients undergoing treatment are often at risk for infertility or subfertility. Healthcare providers do not consistently deliver fertility information prior to therapy. Our objective was to assess if development and implementation of a fertility guideline improves the frequency of pre-treatment fertility discussions with pediatric cancer families. Methods: This retrospective cohort study analyzed all consecutively eligible patients over two time periods. The pre-guideline time period was 18 months prior to implementation and the post-guideline time period was 12 months after implementation. Guideline implementation included an education session with oncology staff. Eligible patients were < 19 years old at cancer diagnosis and received chemotherapy and/or radiation therapy. Patients treated with palliative intent were excluded. Pre-guideline rate of pre-treatment fertility discussions was estimated at 40%. An estimated 40 participants in the post-guideline cohort can detect a 30% increase in fertility discussions with β 0.8 and α 0.05. Exploratory analysis assessed factors associated with the frequency of fertility risk discussions. Results: Ninety-five patients were included. Fifty-seven percent were < 10, 26% were 10-15, and 17% were ≥ 16 years old. Pre- and post-guideline cohorts are compared in table. In the pre-guideline cohort, 41% of patients had a discussion about risks of fertility impairment documented, while post-guideline cohort had 49% documented ( p = 0.531). Exploratory assessment of combined cohorts found males (OR 0.2.7, 95% CI 0.1.2-6.3-0.87) and patients ≥ 10 years old (OR 5.0, CI 2.1-12.1) were more likely to receive fertility discussions prior to therapy. Radiation and cancer type did not influence whether fertility discussions occurred. Conclusions: Implementation of a fertility guideline did not increase discussions of fertility risk, and less than half of patients had a documented fertility risk discussion. Male patients and age ≥ 10 years old were more likely to have documented discussions about risks to future fertility. Effective strategies are needed to improve the rate of discussions regarding fertility risk to ensure families receive this information prior to therapy. [Table: see text]

Long-term alterations in somatosensory functioning in survivors of childhood cancer

ABSTRACT

Cancer and its treatment can have lasting consequences on somatosensation, including pain, which is often underrecognized and undertreated. Research characterizing the impact of cancer on pain and sensory processing in survivors of childhood cancer is scarce. This study aimed to quantify generalized differences in pain and sensory processing in survivors of childhood cancer compared with reference data using a standardized thermal and mechanical quantitative sensory testing (QST) protocol. The association between demographic, clinical (eg, leukemia vs other cancers and treatment exposures), and psychosocial (eg, anxiety and pain catastrophizing) variables and sensitivity to pain and sensory stimuli were also evaluated. Participants were 56 survivors of various types of childhood cancer (52% male, Mage = 13.5 years, SD = 3.2, range = 8-17 years). On average, children were 7 years (SD = 4.1, range = 1.2-16.5) post treatment. Almost all participants (86%) had at least 1 abnormal QST parameter compared with age- and sex-matched reference data; however, few participants self-reported the presence of sensory abnormalities. Generally, participants exhibited reduced sensitivity across the QST parameters examined (Ps < 0.05, ds = 0.40-3.45). A significant minority (45%) also exhibited pain sensitization (P <0.001, d = 0.42). Several risk factors for changes in sensory processing were identified, including current age, history of leukemia, certain treatment exposures (eg, vincristine cumulative dose, major surgery, and bone marrow or stem cell transplant), time off treatment, and higher anxiety and pain catastrophizing scores. Overall, this study demonstrated that somatosensory changes are prevalent in survivors of childhood cancer years after the completion of treatment. Future research is needed to understand long-term implications of altered somatosensation in this complex population.

Measuring Fear of Cancer Recurrence in Survivors of Childhood Cancer: Development and Preliminary Validation of the FCRI-Child and FCRI-Parent Versions

OBJECTIVE

Fear of cancer recurrence (FCR) is a common and distressing psychosocial concern for adult cancer survivors. Data on this construct in child survivors is limited and there are no validated measures for this population. This study aimed to adapt the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF) for survivors of childhood cancer aged 8-18 years (FCRI-C) and their parents (FCRI-P) to self-report on their own FCR and to examine the initial psychometric properties.

METHODS

The FCRI-SF was adapted through expert panel input and cognitive interviews with child survivors <18 years. The factor structure, internal consistency and construct and criterion validity of the FCRI-C and FCRI-P were examined in 124 survivors of childhood cancer (43% female; M_age =14.58 years, SD=2.90) and 106 parents (90% mothers).

RESULTS

All FCRI-SF items were retained for the FCRI-C with simplified language. The internal consistencies of the FCRI-C (α= .88) and FCRI-P (α= .83) were good. Exploratory factor analyses yielded one-factor structures for both measures. Higher scores on the FCRI-C and FCRI-P were associated with greater intolerance of uncertainty and pain catastrophizing. Higher child FCR was also related to more hypervigilance to bodily symptoms. Parents with higher FCR reported contacting their child's doctors and nurses and scheduling medical appointments for their child more frequently. Children reported significantly lower FCR compared to parents.

CONCLUSIONS

The FCRI-C and FCRI-P demonstrated strong reliability and preliminary validity. This study offers preliminary data to support the use of the FCRI-C and FCRI-P to measure FCR in survivors of childhood cancer aged 8-18 years and their parents.

Development of System Performance Indicators for Adolescent and Young Adult Cancer Care and Control in Canada

OBJECTIVES

To develop an expert-group, consensus-based list of system performance indicators to be used for monitoring, evaluating, and benchmarking progress for cancer care and control in adolescents and young adults (AYAs) in Canada.

METHODS

A national multidisciplinary panel of AYA oncology experts was convened; they prepared a literature review and undertook a brainstorming exercise to create a comprehensive list of indicators based on a previously defined framework for AYA cancer care and control in Canada. A modified Delphi process was then undertaken to cull the list based on 3 quick screen criteria. Three rounds of ranking were required. The fourth stage employed a face-to-face meeting, and the final stage utilized a survey to rank the indicators on the basis of importance and feasibility.

RESULTS

Nineteen participants contributed to the 5-stage process. From an initial list of 114 indicators, 14 were ultimately endorsed, representing 5 themes: active care, survivorship, psychosocial issues, palliative care, and research. The 5 highest ranked indicators were assessed as very to moderately feasible, with only a single indicator (clinical trial enrollment) in the top 5 assigned a least feasible ranking.

CONCLUSION

The 14 indicators provide a starting point for the development of a standard set of metrics for AYA cancer care and control in Canada and have potential for international utility.

After Childhood Cancer: a Qualitative Study of Family Physician, Parent/Guardian, and Survivor Information Needs and Perspectives on Long-Term Follow-up and Survivorship Care Plans

Despite support for the provision of a survivorship care plan (SCP) to every cancer survivor, there is a lack of understanding of the needs and preferences of key stakeholders. We examined perspectives of a novel personalized SCP for childhood cancer survivors (CCS), their family, and family physicians (FP). We conducted semi-structured telephone interviews with a purposefully selected sample of CCS, parents/guardians, and FPs. Data included responses to stakeholder cancer care information needs, concerns with or gaps in communication, the perceived role of the FP in the long-term management of CCS care, utility of the SCP, preferred format, and suggestions for improvement. A deductive content analysis was conducted. Twenty-four participants including 8 CCS, 10 parents/guardians, and 6 FPs completed an interview. Four main and several sub-categories emerged. Core categories were coded as (1) informative reference, (2) coordination of follow-up, (3) barriers to follow-up care, and (4) suggestions for improvement and future implementation. The majority of participants preferred an electronic- or web-based format. Overall, the SCP was seen as an informative and concise resource. The SCP was thought to be a valuable tool to foster communication and empower CCSs to become more fully engaged in their own cancer-related health care. FPs viewed the SCP as a useful resource to facilitate and guide the long-term management of the CCS. In addition to the treatment summary, a comprehensive follow-up timeline, personalized lifestyle information, and details on how to access additional psychosocial support were highlighted as important components.

When "a headache is not just a headache": A qualitative examination of parent and child experiences of pain after childhood cancer

OBJECTIVE

Today, more than 80% of children diagnosed with cancer are expected to survive. Despite the high prevalence of pain associated with the diagnosis and treatment of childhood cancer, there is a limited understanding of how having cancer shapes children's experience and meaning of pain after treatment has ended. This study addresses this gap by exploring childhood cancer survivors' (CCS') experiences of pain from their perspective and the perspective of their parents.

METHODS

Twenty semi-structured interviews were completed with CCS (50% female; mean age = 13.20 y, range = 8-17 y) and their parents (90% mothers). Data were analyzed using interpretive phenomenological analysis.

RESULTS

Analyses revealed three superordinate themes present in the data: (a) pain is a changed experience after childhood cancer; (b) new or ambiguous pains may be interpreted by CCS and parents as a threat of disease recurrence, late effects, or a secondary cancer; and (c) pain interpretation occurs within the broader context of how CCS and parents appraise their cancer experience. Parents generally appraised their child's cancer and pain as more threatening and were influential in guiding their child's interpretations.

CONCLUSIONS

The cancer experience played an important role in shaping CCS' and their parents' experience and interpretation of pain in survivorship. This study provides novel data to inform the development and refinement of new and existing conceptual models of pain and symptom perception after cancer. The results also point to key areas for future investigation and clinical intervention to address the issue of pain in cancer survivorship.

Physician needs and preferences for information about long-term follow-up and care of survivors of childhood cancer

66

Background: The treatments that childhood cancer survivors (CCS) undergo can lead to an increased risk of other health problems later in life, and risk-based follow-up care is necessary throughout their lifetime. Regrettably, family physicians caring for CCS often report having no record of their patients’ past disease, treatment history, or need for follow-up. As the large majority of CCS will transition from specialized pediatric oncology care to generalized adult care in the community, detailed treatment summaries and Survivorship Care Plans (SCP) are needed to ensure that both the survivor and their care providers are adequately informed of the survivors diagnosis, treatment(s), potential risk for late effects, and long-term surveillance and healthcare needs. This qualitative study sought to explore the needs, preferences, and the perceived utility of SCP for family physicians (FP) caring for CCS. Methods: Using publically available Children’s Oncology Group guidelines, a de-identified sample SCP indicating the diagnosis, treatment(s) received, and follow-up recommendations for a common childhood cancer diagnosis was automatically generated using a newly developed algorithm and patient data from the Cancer in Young People – Canada registry. Semi-structured telephone interviews with six FP that have a known CCS in their practice were then used to gain insight into the FP perceived role in the long-term management and care of CCS, their cancer information needs, concerns with communication, their perceived utility of the SCP, and preferred format(s) for receiving the SCP. The constant comparative method was used for thematic analysis. Results: The key themes emerging from the six completed interviews include a lack of confidence among FP in their ability to care for CCS and a need for additional knowledge and resources. FP also identified psychological barriers to cancer care discussions with CCS and identified a patient need for greater psychological support. Overall, SCP were viewed as helpful. Conclusions: SCP are perceived to be of benefit to FP of CCS as they serve to increase their knowledge of patient diagnosis, treatments received, and suggested risk-based follow-up.

Patterns of tumor progression after radiotherapy for low-grade gliomas: analysis from the computed tomography/magnetic resonance imaging era

Postoperative radiotherapy for low-grade gliomas has been shown in retrospective series to improve survival, compared with surgery alone. To determine the proper radiotherapy treatment volume and dose, an understanding of the patterns of failure with current radiotherapy techniques is necessary. We studied 30 consecutive patients who had a pathologic diagnosis of low-grade nonpilocytic glioma treated in our department between 1975 and 1994. Before radiotherapy, 5 patients underwent biopsy, 22 had subtotal resection, and 3 had gross total excision. All had pre- and posttreatment computed tomographic (CT) or magnetic resonance imaging (MRI) scanning. Megavoltage radiotherapy was delivered to shrinking partial (22 patients) or whole-brain (8 patients) fields. Median dose was 59.4 Gy (range, 46.4-64 Gy) in 1.8- to 2-Gy fractions. Median follow-up was 44 months (3-215 months) for the cohort and 105 months for survivors. For the entire series, 5-year overall survival and relapse-free survival rates were 50% and 41%, respectively. Sixteen patients (53%) progressed at a median of 30 months. At the time of failure, 71% (5 of 7) of pathologically evaluated tumors were of high grade. Recurrence originated within the field in all patients. Higher 5-year overall survival and relapse-free survival rates were associated (p < 0.001) with preradiotherapy functional status 1 versus functional status 2 through 4 (60% vs. 0% and 55% vs. 0%, respectively). Seizure as initial presentation was favorable over other symptoms (5-year overall survival, 64% versus 14%; p = 0.057). We conclude that 1) low-grade nonpilocytic gliomas can transform to high-grade lesions after treatment with conventional radiotherapy, 2) recurrence uniformly occurs within the treatment volume, and 3) pretreatment functional status correlates prognostically with survival. The local pattern of failure suggests that radiotherapy dose escalation within conformal fields could improve results.

Potential underdosing with the use of electron beam therapy in patients with cervical adenopathy and advanced head and neck cancer

To define the adequacy of electron beam therapy in the treatment of N1-N3 head and neck cancer, 24 patients with primary head and neck cancers and N1-N3 cervical adenopathy received primary radiation therapy with or without chemotherapy for definitive control of their disease. All patients underwent computerized tomography (CT) to assist in the design of treatment to the posterior neck with electron beams after photon therapy to the level of spinal cord tolerance. Treatment with electrons to the posterior neck in patients with N1 disease was adequate in 92% (11/12) of patients. However, in patients with N2 and N3 disease, electron beam treatment failed, because of spinal cord tolerance problems, to cover the disease adequately in 92% (11/12). It is concluded that CT should be employed routinely in patients with N1-N3 neck disease to determine the proper electron energy prescription. For some patients, electron beam may not be appropriate, making it necessary to use individual planning to treat adequately the neck disease and avoid the spinal cord.

Vertebral artery injury after acute cervical spine trauma: rate of occurrence as detected by MR angiography and assessment of clinical consequences

OBJECTIVE

The purposes of this study were to assess prospectively the frequency of vertebral artery injuries after major acute cervical spine trauma as determined by MR angiography and to assess the clinical consequences of these injuries.

SUBJECTS AND METHODS

During a 6-month period, 37 patients who had major acute nonpenetrating cervical spine trauma were examined with MR imaging, usually within 24 hr of the injury. Routine spin-echo and gradient-echo images were supplemented by two-dimensional time-of-flight MR angiography of the extracranial head and neck vessels. The vertebral arteries were independently assessed by two neuroradiologists for nonvisualization, focal narrowing, or focal widening. Two patients had conventional angiographic correlation. The medical records of these 37 patients were also reviewed to determine the type of spinal injury, neurologic deficit on admission, and evidence of an intracranial neurologic deficit due to vertebral artery injury. The MR angiograms of 37 control subjects were interpreted to help determine the specificity of MR angiography; those studies were assessed only for the presence or absence of the vertebral arteries.

RESULTS

Findings on MR angiograms were abnormal in nine patients (24%). In seven cases, one vertebral artery was diagnosed as nonvisualized (occluded) or focally narrowed; one patient had bilateral vertebral artery injuries; and one patient had nonvisualization of the left common carotid and left vertebral arteries. In all 37 control subjects, both vertebral arteries were identified on MR angiograms. A significant difference in the frequency of vertebral artery nonvisualization (occlusion) was found between the trauma and control populations. The patient with bilateral vertebral artery injuries died 2 days after hospital admission of a massive infarction of the right cerebellar hemisphere. The other eight patients with vertebral artery injuries, and the remaining 28 patients with normal findings on MR angiograms, had no intracranial neurologic deficits that could be ascribed to a major arterial injury.

CONCLUSION

In our experience, vertebral artery injuries due to major cervical spine trauma as determined by MR angiography are common. Although these vascular abnormalities usually remain clinically occult, a small percentage of patients may suffer devastating neurologic complications of posterior fossa infarction. Noninvasive assessment of the vertebral arteries by means of MR imaging should be an integral part of the evaluation of the acutely injured cervical spine.

Potential underdosing with the use of electron-beam therapy in patients with cervical adenopathy and advanced head and neck cancer

To define the adequacy of electron-beam therapy in the treatment of N1-N3 head and neck cancer, 24 patients with primary head and neck cancers and N1-N3 cervical adenopathy received primary radiation therapy with or without chemotherapy for definitive control of their disease. All patients underwent computerized tomography (CT) to assist in the design of treatment to the posterior neck with electron beams after photon therapy to the level of spinal cord tolerance. Treatment with electrons to the posterior neck in patients with N1 disease was adequate in 92% (11/12) of patients. However, in patients with N2/N3 disease, electron beam failed, because of spinal-cord tolerance problems, to adequately cover disease in 92% (11/12). It is concluded that CT should be routinely employed in patients with N1-N3 neck disease to determine the proper electron-energy prescription. For some patients, electron beam may not be appropriate, making it necessary to use individual planning to treat adequately the neck disease and avoid the spinal cord.

Intervertebral disc injury complicating cervical spine trauma

The incidence of acute herniated nucleus pulposus was determined in 55 patients with cervical spine trauma. A standardized protocol and a 1.5-T magnetic resonance image scanner was used to document a 42% incidence of acute herniated nucleus pulposus in patients studied within 72 hours of injury. The incidence of herniated nucleus pulposus was correlated with the patients' presenting neurologic status and mechanism of injury. The incidence of herniated nucleus pulposus was highest in patients with bilateral facet dislocations (80%) and anterior cord syndromes (100%). There was no statistically significant correlation between the incidence of herniated nucleus pulposus and patients' age or sex.

Enhanced resolution of pituitary fossa by three-dimensional fat-suppressed gradient-echo magnetic resonance: before and after gadolinium enhancement

In imaging small anatomical parts such as the pituitary fossa, thin sections enhance the spatial resolution. Gradient recalled images (GRASS) using three-dimensional volume data produce ultrathin contiguous sections with a high signal-to-noise ratio. In this study, conventional spin-echo magnetic resonance images (MRIs) of the pituitary fossa were compared to three-dimensional gradient recalled MRI in 5 volunteers and 10 patients suspected of having pituitary gland abnormalities. Utility of fat suppression was also assessed, along with gadolinium enhancement. Conventional spin-echo and three-dimensional spoiled GRASS images, three-dimensional spoiled GRASS images without and with fat suppression (Group II), and three-dimensional spoiled GRASS images with fat suppression before and after gadolinium enhancement were compared. Three-dimensional spoiled GRASS images provided better delineation of the pituitary fossa structures. There was differential enhancement between the normal gland and pituitary tumors. The fat suppression technique following gadolinium administration helped separate the high signal of tumor from the high signal of the clivus marrow. In conclusion, T1-weighted three dimensional gradient-echo images with fat suppression following gadolinium enhancement appear promising in evaluation.

Magnetic resonance imaging of acute cervical spine trauma. Correlation with severity of neurologic injury

Prior to the advent of computer-assisted imaging techniques, conventional radiographic studies did not accurately depict the severity of soft tissue injury (spinal cord and paravertebral tissue) attending severe spinal trauma. Computed tomography scanning is clearly superior to plain radiography in the demonstration of osseous fractures and impactions, but this modality does not clearly depict ligamentous or disc injuries and does not image the spinal cord directly. The authors' preliminary experience indicates that magnetic resonance imaging (MRI) more accurately defines the extent of soft tissue damage in the zone of injury. In this study, the authors correlate these objective imaging techniques with findings on neurologic exam. Seventy-eight patients with cervical spine injuries admitted to the Regional Spinal Cord Injury Center of the Delaware Valley between August 1987 and January 1989 were evaluated with surface-coil MRI on a 1.5-Tesla unit. Fifty-nine patients were studied within 7 days of injury. Image sequences consisting of T1-, proton density, and T2-weighted images were obtained in saggital views. Axial gradient recalled acquisitions in the steady state (GRASS) images were obtained from most patients. We learned that certain patterns of MRI signal were associated with severe neurologic deficit. These include: 1) intramedullary hematoma and 2) spinal cord contusion associated with edema encompassing more than one spinal segment. Magnetic resonance imaging findings also correlated with less severe injury and include 1) normal spinal cord signal and 2) small focal contusions associated with edema encompassing one spinal segment or less.

Microspectrophotometric studies of Romanowsky stained blood cells. IV. Maturation of myeloid and erythroid cell lines in bone marrow

A quantitative characterization has been made of azure B/eosin stained cells from bone marrow. Two cell lines were followed: the myeloid line (white cell blast, promyelocyte, neutrophilic myelocyte, neutrophilic metamyelocyte, neutrophilic band, neutrophilic segmented) and the erythroid line (rubriblast, prorubricyte, rubricyte, metarubricyte, diffusely basophilic erythrocyte, erythrocyte). A consensus scheme was used to obtain the "true" classification of the cells. Cell types were characterized by three methods: absorbance spectra, dye binding, and chromaticities. Within both cell lines nuclear maturation is accompanied by an overall increase in peak absorbance with little shift in the position of the maximum. Generally, binding of azure B and eosin increases; azure B dimer/monomer ratios show a slight downward trend during maturation. Changes in chromaticities are to bluish purples of increasing saturation. Cytoplasmic changes accompanying maturation are much more striking than nuclear changes, and again the two cell lines show similarities. Generally, there is decreased binding of azure B during maturation. In the erythroid line, the Soret band of hemoglobin becomes increasingly prominent. Chromaticities change from bluish purples to purplish pinks, particularly in the erythroid line.
