The impact of cancer on the physical, psychological and social well-being of childhood cancer survivors

PURPOSE

Notwithstanding the advances in medical treatment, childhood cancer survivors are at risk of adverse physical, psychological and social effects of the cancer treatment. The purpose of this study was to examine the impact of cancer and its treatments on the physical, psychological and social well-being of Hong Kong Chinese childhood cancer survivors.

METHOD

A total of 137 childhood cancer survivors (aged 9-16 years), who had their medical follow-up in an oncology out-patient clinic were invited to participate in the study. Participants were asked to respond to the standardized measures of depressive symptoms and self-esteem. Additionally, 15 participants from the group were selected for a semi-structured interview.

RESULTS

The results revealed that more than half of the participants presented depressive symptoms. Results also found that the mean depressive symptom scores for childhood cancer survivors were statistically significant higher than those of school children without cancer (p = 0.01), while the mean self-esteem scores for the survivors were statistically significant lower (p < 0.01). Additionally, qualitative interviews indicated that cancer and its treatments have great impact on the daily life of childhood cancer survivors.

CONCLUSION

The study reveals that cancer and its treatments have a great impact on the physical, psychological and social well-being of survivors. It is essential for healthcare professionals to develop appropriate interventions with the aim of promoting physical, psychological and social well-being for these children. Most importantly, it is crucial to help them develop a positive view of the impact that the cancer experience has upon their lives.

Quality of life (QOL) in patients with osteosarcoma

Patients with osteosarcoma undergo extensive treatment using aggressive chemotherapy and surgery and this can have substantial acute and long-term effects on patients. In particular, quality of life (QOL) can be affected. It is important that QOL be examined to see how it is influenced. It is also important to determine who is at highest risk for impaired QOL and develop appropriate interventions. QOL is one of several outcomes that are influenced by the diagnosis and treatment of osteosarcoma. Other outcomes include function, disability, and body image. Currently, gaps exist in our knowledge of QOL in osteosarcoma patients and prospective studies are needed.

International collaboration is feasible in trials for rare conditions: the EURAMOS experience

The introduction of multi-agent chemotherapy dramatically improved the outcome for patients with osteosarcoma. However, we appear to have reached a plateau in outcome with a long-term event-free survival of 60-70%. Therefore, detection of further improvements will likely require larger numbers of patients. This goal is best achieved via randomized clinical trials (RCTs) requiring large-scale cooperation and collaboration. With this background, four multinational groups agreed on the merits of collaboration: Children's Oncology Group (COG), Cooperative Osteosarcoma Study Group (COSS), European Osteosarcoma Intergroup (EOI) and Scandinavian Sarcoma Group (SSG); they designed a study to determine whether altering postoperative therapy based on histological response improved the outcome. The study design includes a backbone of 10 weeks of preoperative therapy using MAP (methotrexate, Adriamycin and cisplatin). Following surgery, patients are stratified according to histological response. Patients classified as "good responders" (>or=90% necrosis) are randomized to continue MAP or to receive MAP followed by maintenance pegylated interferon, while "poor responders" (<90% necrosis) are randomized to either continue MAP or to receive MAPIE (MAP+ifosfamide, etoposide). The design includes the registration of 1,400 patients over 4 years as well as the evaluation of quality of life using two different instruments. The group has established an efficient infrastructure to ensure successful implementation of the trial. This has included the EURAMOS Intergroup Safety Desk, which has established an international system for SAE, SAR and SUSAR reporting to the relevant competent authorities and ethics committees for each participating country. The group has also developed trial site monitoring and data center audits with funding from the European Science Foundation (ESF). The ESF has also funded three training courses to familiarize institutional staff with the requirements of multinational GCP trials. We have established a successful collaboration, and as of February 2008, 901 patients have been enrolled (COG 448; COSS 226; EOI 181; SSG 46) from 249 institutions in 16 different countries. As expected, 80% of the patients are <18 years of age, and accrual into the Quality of Life sub-study is proceeding as planned with 90% of the subjects agreeing to participate. International awareness is increasing and procedures for applicant countries wishing to join the collaboration have been implemented. Details about EURAMOS can be found at www.euramos.org. International trials in rare diseases are practicable with appropriate funding, planning and support. Although the implementation of such trials is difficult and time consuming, it is a worthwhile effort to rapidly complete RCTs and identify interventions that will improve the outcome of all osteosarcoma patients.EURAMOS-1 is the fastest accruing osteosarcoma trial and is already the largest osteosarcoma study conducted.

Surviving childhood cancer: the impact on life

With modern therapies, most children diagnosed with cancer are expected to reach adulthood. Therefore, there are large and ever-increasing numbers of children and young adults in our population who are survivors of childhood cancer. Many of the therapies responsible for improved cancer survival rates can also damage normal cells and tissues. As more children survive cancer, the physical and emotional costs of enduring cancer therapy become increasingly important. Although most childhood cancer survivors are now expected to survive, they remain at risk for relapse, second malignant neoplasms, organ dysfunction, and a negative psychologic impact. Individual risk is quite variable and is dependent on multiple factors including the type and site of cancer, the therapy utilized, and the individual's constitution. The risks are likely to change as we learn more about the specific long-term effects of cancer therapy, develop more refined and targeted therapies, and develop and apply more effective preventative strategies or therapeutic interventions. Guidelines for long-term follow-up have been established and are available to help facilitate appropriate monitoring of and care for potential late effects.

Evaluating physical function in an adolescent bone tumor population

BACKGROUND

Survival rates for patients with bone tumors have increased dramatically over the past few decades. Unfortunately, many patients face functional limitations resulting from disease management, but there is little evidence regarding physical functioning in adolescents with bone tumors. This lack is largely due to the absence of a standardized measure for evaluating adolescent sarcoma physical functioning. This review discusses considerations in searching for a measure of adolescent physical functioning, evaluates measures previously used in assessing functional outcome in young sarcoma patients, reviews self-report measures of pediatric physical functioning, and makes recommendations for future research.

PROCEDURE

Electronic databases were searched for studies published between 1980 and 2004. Studies examining physical functioning in adolescent sarcoma patients and those describing measures of pediatric physical functioning were included.

RESULTS

The study includes measures previously used in the adolescent bone tumor literature (Musculoskeletal Tumor Society, Mankin, Groningen Activity Restriction Scale, Toronto Extremity Salvage Score [TESS]), and three measures of pediatric physical function (Functional Disability Inventory, Pediatric Outcomes Data Collection Instrument [PODCI], Activities Scale for Kids [ASK]). The TESS, PODCI, and ASK each met at least four of the outlined applicability and feasibility components.

CONCLUSION

The search for a measure of physical functioning for adolescent sarcoma patients requires an exploration of many developmental and measurement issues. Based on the sensibility review presented, the TESS, PODCI, and ASK are recommended for further evaluation of content and of the measurement properties of reliability, validity, and responsiveness, prior to their use in evaluating adolescent sarcoma patients.

Education, employment, insurance, and marital status among 694 survivors of pediatric lower extremity bone tumors: a report from the childhood cancer survivor study

BACKGROUND

With increasing numbers of childhood cancer survivors, direct sequelae of cancer therapy and psychosocial outcomes are becoming more important. The authors described psychosocial outcomes (education, employment, health insurance, and marriage) for survivors of pediatric lower extremity bone tumors.

METHODS

The long-term follow-up study of the Childhood Cancer Survivor Study is a multiinstitutional cohort study comprising 14,054 individuals who have survived for 5 or more years after treatment for cancer diagnosed during childhood or adolescence. Baseline demographic and medical information were obtained. Six hundred ninety-four survivors had osteosarcoma or Ewing sarcoma of the lower extremity or pelvis and were classified by amputation status and by age at diagnosis. The median age at diagnosis was 14 years old with a median of 16 years of follow up since diagnosis. Demographic characteristics were used to analyze the rates of psychosocial outcomes.

RESULTS

Amputation status and age at diagnosis did not significantly influence any of the measured psychosocial outcomes. Education was a significant positive predictor of employment, having health insurance, and being currently in their first marriage. Male gender predicted ever being employed and female gender predicted having health insurance and marriage. When compared with siblings, amputees had significant deficits in education, employment, and health insurance.

CONCLUSIONS

Overall, no differences between amputees and nonamputees were found. However, gender and education play a prominent role. When compared with siblings, amputees in this cohort may benefit from additional supports.
