Late effects of therapy in adult survivors of osteosarcoma and Ewing's sarcoma

Psychological Well-Being, Self-Esteem, Quality of Life and Gender Differences as Determinants of Post-Traumatic Growth in Long-Term Knee Rotationplasty Survivors: A Cohort Study

Rotationplasty (RP) is a special surgical technique for bone tumors of the lower limb and is the chosen procedure for children under 6 with bone sarcoma in the distal femur. Leg reconstruction results in an unusual aspect of the limb potentially giving life-long emotional outcomes, especially considering the young age of most RP patients. Although the high level of the quality of life of these patients has been previously reported, aspects related to long-term psychological well-being, self-esteem and life satisfaction, particularly regarding the gender, procreation and parenting, have never been explored. The aim of this study was to assess the general degree of psychological well-being of RP patients, with specific reference to gender, procreation and parenting. Twenty long-term RP survivors of high-grade bone sarcoma participated in the study. They were administered the following validated questionnaires: HADS for psychological well-being (degree of anxiety and depression), Temperament and Character Inventory (TCI), RSES for self-esteem, SF-36 for quality of life, SWLS extended to life satisfaction, and ABIS for body image integration. Data on education, marriage, employment and parenthood were gathered. All the scores obtained were very close to normal references. The only gender difference was found for the TCI Cooperativeness scale, which was higher in women than in men. A satisfactory psychological well-being in terms of both self-esteem and integration of the prosthetic joint limb into one's body image, with relatively limited amount of anxiety/depression, good quality of life, and good temperament and character traits, was found. No major gender differences were reported.

Quality of Life and Limb Functionality in Adolescents and Young Adults Surviving Bone Tumors in the Lower Extremity in a Developing Country: A Cross-Sectional Study

Introduction Due to higher survival rates among patients with bone tumors, there is a growing interest in determining these individuals' limb functionality and psychosocial prognosis.

Objectives This study aimed to analyze the differences in functionality and quality of life (QoL) related to health in patients diagnosed with a malignant bone tumor during childhood, according to the type of surgery performed.

Materials and Methods A cross-sectional study was performed for patients older than 14 years who treated for osteosarcoma or Ewing's sarcoma of the lower limb by who receiving surgery. To assess lower limb functionality and QoL among patients surviving malignant bone tumors, 19 patients surviving osteosarcoma or Ewing's sarcoma of the lower extremity were studied. An evaluation of functionality and QoL was done using the “Enneking and Medical Outcomes Study Short-Form 36 scales.” We compared the functional results according to the surgical technique used. Categorical variables were compared according to the Mann–Whitney and Kruskal–Wallis tests, with an established 95% level of significance.

Results QoL among patients who had conservative surgery was not significantly better than amputee patients in the physical or mental aspects, nor in any of their components. Limb functionality, according to Enneking's staging, was significantly higher in non-amputee patients (p = 0.035).

Conclusion According to the data analysis done in this study, the QoL was found to be not significantly different, based on the type of surgery performed; however, there were differences in limb functionality.

Employment among Childhood Cancer Survivors: A Systematic Review and Meta-Analysis

To date, there are heterogeneous studies related to childhood cancer survivors’ (CCS) employment rates. Given the importance of this topic, we aimed to perform a systematic review and meta-analysis to investigate the prevalence of employment among CCS and to examine its association with socio-demographic and clinical factors. We followed the PRISMA guidelines to search for pertinent articles in relevant electronic databases. Eighty-nine articles comprising 93 cohorts were included. The overall prevalence of employment was 66% (CI: 95% 0.63–0.69). Subgroup meta-analyses showed that lower rates were found for central nervous system tumor survivors (51%, CI: 95% 0.43–0.59), and for CCS treated with cranial-radiotherapy (53%, CI: 95% 0.42–0.64) or haematopoietic stem-cell transplantation (56%, CI: 95% 0.46–0.65). The studies conducted in Asia highlighted employment rates of 47% (CI: 95%, 0.34–0.60). Univariate meta-regressions identified the following socio-demographic factors associated with higher rates of employment: a female gender (p = 0.046), a higher mean age at the time of investigation (p = 0.00), a longer time since diagnosis (p = 0.00), a higher educational level (p = 0.03), and a married status (p = 0.00). In conclusion, this systematic review and meta-analysis provides evidence that two-thirds of CCS are employed worldwide. Identifying vulnerable groups of CCS may allow for the design of multidisciplinary support strategies and interventions to promote employment in this population.

Large variation in assessment and outcome definitions to describe the burden of long-term morbidity in childhood cancer survivors: A systematic review

We systematically reviewed outcome assessment methods, outcome classification, and severity grading of reported outcomes in studies investigating the burden of physical long-term morbidity in childhood cancer survivors (CCS). A MEDLINE and EMBASE search identified 56 studies reporting on three or more types of health conditions in 5-year CCS, for which information was extracted on outcome types and classification, methods of outcome ascertainment, and severity grading. There was substantial variability in classification and types of health conditions reported and in methods of outcome ascertainment. Only 59% of the included studies applied severity grading, mainly the common terminology criteria of adverse events. This large variation in assessment and definition of the burden of physical long-term morbidity in CCS challenges interpretation, comparison, and pooling data across studies. Global collaboration is needed to standardize assessments and harmonize definitions of long-term physical morbidity and associated outcomes in childhood cancer survivorship research.

Exercise and Physical Activity in Patients with Osteosarcoma and Survivors

Exercise has the potential to positively affect patients with osteosarcoma by improvement of function, mitigation of disability, and maintenance of independence and quality of life. Exercise may also directly impact cancer treatment efficacy. This chapter examines the feasibility and use of exercise or physical activity as therapy in the treatment of osteosarcoma and its survivors. It additionally presents the benefits of physical activity as treatment and rehabilitation both preoperatively (prehabilitation) and postoperatively. This chapter will also discuss barriers to exercise and physical activity for patients with osteosarcoma and its survivors, emphasizing the need for a comprehensive and cohesive support system to promote its incorporation into patient treatment plans and ensure compliance.

Prevalence and Predictors of Frailty in Childhood Cancer Survivors and Siblings: A Report From the Childhood Cancer Survivor Study

PURPOSE

To estimate the prevalence of frailty among childhood cancer survivors and to determine the direct and indirect effects of treatment exposures, lifestyle factors, and severe, disabling, and life-threatening chronic condition on frailty.

METHODS

Childhood cancer survivors (≥ 5 years since diagnosis), treated between 1970 and 1999 when < 21 years old (n = 10,899; mean age, 37.6 ± 9.4 years; 48% male, 86% white) and siblings were included (n = 2,097; mean age, 42.9 ± 9.4 years). Frailty was defined as ≥ 3 of the following: low lean mass, exhaustion, low energy expenditure, walking limitations, and weakness. Generalized linear models were used to evaluate direct and indirect associations between frailty and treatment exposures, sociodemographic characteristics, lifestyle factors, and chronic condition.

RESULTS

The overall prevalence of frailty among survivors was 3 times higher compared with siblings (6.4%; 95% CI, 4.1% to 8.7%; v 2.2%; 95% CI, 1.2% to 3.2%). Survivors of CNS tumors (9.5%; 95% CI, 5.2% to 13.8%) and bone tumors (8.1%; 95% CI, 5.1% to 11.1%) had the highest prevalence of frailty. Survivors exposed to cranial radiation, pelvic radiation ≥ 34 Gy, abdominal radiation > 40 Gy, cisplatin ≥ 600 mg/m², amputation, or lung surgery had increased risk for frailty. These associations were partially but not completely attenuated when sociodemographic characteristics, lifestyle factors, and chronic conditions were added to multivariable models. Cranial radiation (prevalence ratio [PR], 1.47; 95% CI, 1.20 to 1.76), pelvic radiation ≥ 34 Gy (PR, 1.46; 95% CI, 1.01 to 2.11), and lung surgery (PR, 1.75; 95% CI, 1.28 to 2.38) remained significant after sociodemographic, lifestyle, and chronic conditions were accounted for.

CONCLUSION

Childhood cancer survivors reported a higher prevalence of frailty compared with siblings. Radiation and lung surgery exposures were associated with increased risk for frailty. Interventions to prevent, delay onset, or remediate chronic disease and/or promote healthy lifestyle are needed to decrease the prevalence of frailty and preserve function in this at-risk population.

Employment status and occupational level of adult survivors of childhood cancer in Great Britain: The British childhood cancer survivor study

The British Childhood Cancer Survivor Study (BCCSS) provides the first detailed investigation of employment and occupation to be undertaken in a large population-based cohort. Previous studies have been limited by design issues such as using small numbers of survivors with specific diagnoses, and involved limited assessment of employment status and occupational level. The BCCSS includes 17,981 5-year survivors of childhood cancer. Employment status and occupational level were ascertained by questionnaire from eligible survivors (n = 14,836). Multivariate logistic regression was used to explore factors associated with employment and occupation, and to compare survivors to their demographic peers in the general population. Employment status was available for 10,257 survivors. Gender, current age, cancer type, radiotherapy, age at diagnosis and epilepsy were consistently associated with being: employed; unable to work; in managerial or non-manual occupations. Overall, survivors were less likely to be working than expected (OR (99% CI): 0.89 (0.81-0.98)), and this deficit was greatest for irradiated CNS neoplasm survivors (0.34 (0.28-0.41)). Compared to the general population, survivors were fivefold more likely to be unable to work due to illness/disability; the excess was 15-fold among CNS neoplasm survivors treated with radiotherapy. Overall survivors were less likely to be in managerial occupations than expected (0.85 (0.77-0.94)). However, bone sarcoma survivors were more likely to be in these occupations than expected (1.37 (1.01-1.85)) and also similarly for non-manual occupations (1.90 (1.37-2.62)). Survivors of retinoblastoma (1.55 (1.20-2.01)) and 'other' neoplasm group (1.62 (1.30-2.03)) were also more likely to be in non-manual occupations than expected.

Psychosexual development and satisfaction in long-term survivors of childhood cancer: Neurotoxic treatment intensity as a risk indicator

BACKGROUND

Risk factors for impairment in psychosexual development and satisfaction among adult survivors of childhood cancer are poorly understood. The authors compared psychosexual outcomes between survivors and healthy controls, and tested whether at-risk survivors can be identified by 1) treatment neurotoxicity or 2) diagnosis.

METHODS

A total of 144 young adult survivors of childhood cancer and 144 matched controls completed questionnaires regarding psychosexual development, sexual satisfaction, and satisfaction with relationship status. Survivors were aged 20 to 40 years and were 5 to 34 years after diagnosis. Using medical chart data, survivors were divided into non-neurotoxic (48 survivors), low-dose (36 survivors), and high-dose (58 survivors) neurotoxic treatment groups.

RESULTS

Apart from having fewer lifetime sex partners, survivors did not appear to differ from controls. However, survivors of brain tumors and any survivor who received high-dose neurotoxic treatment reported the lowest rates of achieving milestones of psychosexual development, whereas sexual and relationship status satisfaction were found to be related to relationship status. Neurotoxic treatment intensity further distinguished between survivors of brain tumors with and without psychosexual impairment.

CONCLUSIONS

The intensity of neurotoxic treatment may be a valuable indicator of risk for psychosexual impairment relative to diagnosis alone. Health care providers should assess romantic/sexual problems among survivors at risk and make referrals if needed. Cancer 2017;123:1869-1876. © 2017 American Cancer Society.

Review : Infertility after chemotherapy: A review of the risks and strategies for prevention

Purpose. Infertility as a late complication of cancer chemotherapy, focusing on specific drug-related ef fects, effects observed in the treatment of certain malignancies, and strategies for prevention is re viewed.

Data Sources. A MEDLINE search of articles from 1966 to present was conducted using the terms infertility, antineoplastics, amenorrhea, azospermia, oogenesis, and spermatogenesis. Additional refer ences were identified using review articles and phar macology textbooks.

Study Selection. All human studies reported in English language were included. Animal studies were included when human data were insufficient or un available.

Data Synthesis. Data on the infertility effects of individual antineoplastic agents are difficult to inter pret for several reasons, including small sample sizes, lack of prechemotherapy fertility assessment, inade quate long-term follow-up, and use of regimens in cluding multiple agents. In general, the incidence and severity of antifertility effects are dependent on the total dosage delivered, duration of therapy, and age at exposure. The alkylating agents have the most signif icant effects on fertility. Fertility outcomes have been reported for several different malignancies, especially in patients cured of Hodgkin's disease and testicular cancer. Information on specific antineoplastic agents and cancers are reviewed. Several methods have been employed to decrease gonadotoxic effects, but none have been effective.

Conclusions. Infertility is a common late com plication of cancer chemotherapy that is receiving increasing attention as the number of cancer survi vors increases. Health care professionals should be aware of infertility risks associated with antineoplastic agents and certain malignancies, and patients should be informed of these risks as treatment decisions are made.

Income in Adult Survivors of Childhood Cancer

Introduction

Little is known about the impact of childhood cancer on the personal income of survivors. We compared income between survivors and siblings, and determined factors associated with income.

Methods

As part of the Swiss Childhood Cancer Survivor Study (SCCSS), a questionnaire was sent to survivors, aged ≥18 years, registered in the Swiss Childhood Cancer Registry (SCCR), diagnosed at age <21 years, who had survived ≥5 years after diagnosis of the primary tumor. Siblings were used as a comparison group. We asked questions about education, profession and income and retrieved clinical data from the SCCR. We used multivariable logistic regression to identify characteristics associated with income.

Results

We analyzed data from 1’506 survivors and 598 siblings. Survivors were less likely than siblings to have a high monthly income (>4’500 CHF), even after we adjusted for socio-demographic and educational factors (OR = 0.46, p<0.001). Older age, male sex, personal and parental education, and number of working hours were associated with high income. Survivors of leukemia (OR = 0.40, p<0.001), lymphoma (OR = 0.63, p = 0.040), CNS tumors (OR = 0.22, p<0.001), bone tumors (OR = 0.24, p = 0.003) had a lower income than siblings. Survivors who had cranial irradiation, had a lower income than survivors who had no cranial irradiation (OR = 0.48, p = 0.006).

Discussion

Even after adjusting for socio-demographic characteristics, education and working hours, survivors of various diagnostic groups have lower incomes than siblings. Further research needs to identify the underlying causes.

Body issues, sexual satisfaction, and relationship status satisfaction in long-term childhood cancer survivors and healthy controls

OBJECTIVE

Research on body image and sexual satisfaction after adult onset cancer has shown significant and lasting impairments regarding survivors' sexuality and romantic relationships. However, knowledge about these topics and their associations in adult survivors of childhood cancer is largely lacking.

METHODS

Participants completed web-based questionnaires concerning body image, body dissociation, sexual satisfaction, and relationship status satisfaction (i.e., satisfaction with either being in a relationship or being single). Survivors (n = 87) and controls (n = 87) were matched on age and gender, with a mean age of 27 years (range: 20-40). Survivors were most often diagnosed with leukemia (46%), at an average of 16 years prior to study participation (range: 6-33 years).

RESULTS

Similar numbers of survivors and controls were single (n = 24/31), in a committed relationship (n = 33/23), or married (n = 30/33). Survivors and controls reported comparable levels of body image, body dissociation, sexual experiences, and sexual and status satisfaction (d = 0.15-0.28). Higher status satisfaction was associated with being in a relationship (compared with being single, β = 0.439), more positive body image (β = 0.196), and higher sexual satisfaction (β = 0.200).

CONCLUSIONS

Adult survivors of childhood cancer were comparable to healthy peers regarding views of their bodies and psychosexual development, which was unexpected. Independent of whether people experienced cancer or not, their status satisfaction was associated with their relationship status, body image, and sexual satisfaction. Future research should explore why sexual and body problems are identified after adult onset cancer, whereas this seems to be less of a problem in childhood cancer survivors.

Psychological resilience in adolescent and young adult survivors of lower extremity bone tumors

BACKGROUND

The psychosocial outcomes of young adult survivors of childhood bone tumors are not well known. This study: (a) examined perceived social support (SS) and benefit-finding (BF) with respect to surgical intervention, gender, and age; (b) compared SS and psychological outcomes to normative values; and (c) examined the relationship between these social and psychological outcomes and sexual functioning.

PROCEDURE

Twenty-eight participants (18-32 years) completed outcome-specific questionnaires for SS, BF, depression, self-worth, and sexual functioning. Surgical intervention was grouped into limb sparing (LS; allograft-fusion and endoprosthesis) and ablative procedures (AMP; amputation or Van Nes rotationplasty). Age at study was grouped into ≤25 or ≥26 years of age.

RESULTS

Compared to normative values, survivors reported significantly less depressive symptoms (P = 0.005), and higher self-evaluations of intellectual capabilities (P = 0.009). No significant differences in SS and BF were found between surgical and age groups. Males perceived significantly higher SS than females (P = 0.027). Significant positive correlations were found between perceived SS and sexual functioning (r = 0.397), sexual experiences (r = 0.423), and satisfaction with sexual relationships (r = 0.408). Negative correlation was found between global SS and depression scores (r = -0.397). Similar correlations were found with the subscales of the SS, depression, and self-worth measures. BF was significantly positively correlated only to SS (r = 0.552).

CONCLUSIONS

Bone tumor survivors, particularly males, demonstrated remarkable psychosocial resiliency with SS possibly serving as a protective factor for survivors' psychological and sexual functioning.

Health related quality of life in adolescent and young adult survivors of lower extremity bone tumors

BACKGROUND

Dramatic increases in survival rates have led to increased interest regarding the health related quality of life (HRQOL) of adolescent and young adult survivors of bone tumors. This study investigated HRQOL and physical disability in adolescent and young adult survivors of lower extremity bone tumors as a function of type of surgical intervention, gender, and age at assessment.

PROCEDURE

Twenty-eight participants (age range 18-32 years) completed three generic and one disease-specific measures of HRQOL and a measure of physical disability. For analysis, surgical intervention was grouped into limb sparing surgeries (LS; allograft fusion and endoprosthesis) and ablative surgeries (AMP; amputation or Van Nes rotationplasty). Age at study was grouped into ≤ 25 years of age and ≥ 26 years of age. The MOS-SF-36, HUI2, HUI3, and EORTC-QLQ-C30 were used to measure HRQOL and the TESS was used to assess physical disability.

RESULTS

Survivors reported HRQOL equivalent to the general population, with the exception of physical functioning. LS reported poorer HRQOL than AMP participants for emotional functioning and fatigue. Males reported better HRQOL compared with females for overall HRQOL, general health, physical functioning, and social functioning. Finally, younger participants generally reported better HRQOL than older participants for overall HRQOL and physical functioning.

CONCLUSIONS

This study identifies LS surgical intervention, female gender and older age as risk factors for reduced HRQOL in adolescent and young adult survivors of lower extremity bone tumors. This study also provides information about what instrument may be most useful in identifying these specific difficulties and subgroups.

Quality of life in survivors of a primary bone tumour: a systematic review

Purpose. We conducted a systematic search of published literature, to assess (i) quality of life (QoL) for survivors of a bone tumour compared with the normal population; (ii) QoL implications following amputation, successful or failed limb salvage; (iii) adaptation of young children to amputation compared with older children or adolescents.

Methods. Electronic databases were searched including Medline, PsycLIT and Cinahl covering the years 1982– 1998.

Results. We identified 11 studies. Regardless of treatment, physical functioning was poor compared with population norms or healthy siblings.There was less consistent evidence regarding emotional functioning. Seven studies compared functioning in amputees and limb salvage patients.Two reported advantages in physical function for the limb salvage group, one for the amputees and the rest no differences. Evidence about social functioning or marriage is inconclusive, but there are suggestions that amputees report more job discrimination.

Discussion. The literature is inconclusive, largely because of methodological problems. These include small and non-representative samples, and lack of sensitive and appropriate measures. Specific gaps in the literature include very little work concerned with psychological outcomes for children, or for those experiencing failed limb salvage. More attention needs to be given to gender differences in emotional response to traumatic surgery.The implications of the results for helping families balance the merits of different treatments are discussed.

Psychosocial and functional outcomes in long-term survivors of osteosarcoma: a comparison of limb-salvage surgery and amputation

BACKGROUND

Traditionally, physicians have believed that limb-salvage surgery has functional and cosmetic advantages over amputation, yet the literature is equivocal. Therefore, we sought to compare the psychosocial and functional outcomes in osteosarcoma survivors after limb-salvage surgery and amputation. We hypothesized there to be neither psychosocial nor functional outcome differences between groups.

PROCEDURE

Participants received treatment of extremity osteosarcoma, had received their cancer diagnosis at least 2 years prior, and were at least 16 years old. A comprehensive set of validated psychosocial and functional measures was used to assess outcome.

RESULTS

Fifty-seven patients participated in this study (33 who underwent limb-salvage surgery and 24 who underwent amputation). Participants had gone 12-24 years since diagnosis and were 16-52 years old at study participation. We used multiple linear regression models to examine differences in quality of life, body image, self-esteem, and social support between the two groups and found no differences. Lower limb function was a significant predictor of quality of life (P < 0.001), whereas surgery type did not impact this relationship. Body image was rated significantly worse by those who underwent late amputation, amputation after failed limb salvage, than by those who did not.

CONCLUSIONS

Participants with more functional lower limbs had better quality of life than did those with less functional lower limbs regardless of whether they underwent amputation or limb-salvage surgery.

Restrictions in daily life after retinoblastoma from the perspective of the survivors

BACKGROUND

Little is known about the impact of retinoblastoma (RB) on the health status of survivors in terms of disabilities and worries, both of which may restrict participation in activities of daily life.

METHODS

In this population-based cross-sectional study, content analysis was used to extract data on perceived restrictions and worries, from semi-structured interviews held with 156 RB survivors aged 8-35 years. The International Classification of Functioning Disabilities and Health (ICF) was used as a framework.

RESULTS

Of all survivors, 55% perceive RB-related restrictions in daily life activities (school, professional career, mobility, self-care, intimate relationships). Young/adolescent survivors (6%) and adult survivors (15%) frequently report anxiety about developing a second primary tumor (SPT). Compared with the general population, RB survivors did not differ in rates of employment or marital status. However, special educational services were more frequently offered, and the level of completed education was lower.

CONCLUSION

RB has influenced the lives of most survivors and, even though their prognosis was good, illness-related restrictions are common. Especially fear of developing SPT and of further loss of vision are important life-long problems, and many survivors had special education needs. The ICF might serve as a bridge between families and professionals, because this classification may facilitate early detection of problems.

Social outcomes in the Childhood Cancer Survivor Study cohort

Difficulties with negotiating and achieving desired social outcomes in life may be exacerbated by the experience of childhood cancer, including adverse effects from therapies used to achieve a cure. This review of previous publications from the Childhood Cancer Survivor Study (CCSS) and other relevant literature provides insight into the prevalence of, and risk factors for, poor educational attainment, less than optimal employment status, and interpersonal relationship issues among long-term survivors of childhood cancer. The impacts of emotional health and physical disability on social outcomes are also examined. Study results suggest that childhood cancer survivors generally have similar high school graduation rates, but are more likely to require special education services than sibling comparison groups. Survivors are slightly less likely than expected to attend college, and are more likely to be unemployed and not married as young adults. Cancers and treatments that result in impairment to the CNS, particularly brain tumors, or that impact sensory functioning, such as hearing loss, are associated with greater risk for undesirable social outcomes, as are emotional health problems and physical disability. This review of relevant data from CCSS and other studies provides information on risk factors for social problems into adulthood. A greater understanding of the long-term social impacts from the diagnosis and treatment of childhood cancer is critically important for developing targeted interventions to prevent or ameliorate adverse psychosocial effects.

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.

Marriage, employment, and health insurance in adult survivors of childhood cancer

INTRODUCTION

Adult survivors of childhood cancer are at risk for disease- and therapy-related morbidity, which can adversely impact marriage and employment status, the ability to obtain health insurance, and access to health care. Our aim was to identify factors associated with survivors' attainment of these outcomes.

METHODS

We surveyed 1,437 childhood cancer survivors who were >18 years old and >10 years past diagnosis. We compared our cohort's data to normative data in the Medical Expenditure Panel Survey and the U.S. Census Bureau's Current Population Surveys. Respondents were stratified by hematologic malignancies, central nervous system tumors, or other solid tumors and by whether they had received radiation therapy.

RESULTS

Most respondents were survivors of hematologic malignancies (71%), white (91%), and working full-time (62%); 43% were married. Compared with age- and sex-adjusted national averages, only survivors of hematologic malignancies who received radiation were significantly less likely to be married (44 vs. 52%). Full-time employment among survivors was lower than national norms, except among survivors of hematologic malignancies who had not received radiation therapy. The rates of coverage of health insurance, especially public insurance, were higher in all diagnostic groups than in the general population. While difficulty obtaining health care was rarely reported, current unemployment and a lack of insurance were associated with difficulty in obtaining health care (P < 0.05 and P < 0.001, respectively). CONCLUSIONS/IMPLICATIONS FOR CANCER SURVIVORS: Subgroups of cancer survivors do experience long-term differences in functional outcomes that should be addressed early. Survivors who are unmarried, unemployed, and uninsured experience difficulty accessing health care needed to address long-term health concerns.

Are there any positive consequences of childhood cancer? A review of the literature

The aim was to investigate whether there are any positive consequences of childhood cancer. Studies published 1990-2005 reporting survivors' descriptions of positive consequences of childhood cancer were identified through a search in the databases CINAHL, PsycINFO, and PubMed. According to a manifest content analysis, positive consequences were referred to three themes: life values, relations to others, and relation to self. A second search in the same databases was conducted to identify studies investigating whether survivors of childhood cancer differ from comparison groups with regard to variables assigned to these themes. In these studies, no conclusions about positive consequences with regard to the theme life values can be drawn, as only one study was identified. In addition, only a small minority of findings from comparative studies indicate that childhood cancer has any positive consequences with regard to relations to others and relation to self. A majority of the results indicate that survivors do not differ from comparison groups, whereas some findings highlight that friendship and marital status are areas of concern, and parenthood and sexuality are areas of potential concern. It is recommended that survivors of childhood cancer are followed up by a multi-professional team, focusing not only on the survivors' health status but also on relations to family, friends, and partners.

Employment status among adult survivors in the Childhood Cancer Survivor Study

BACKGROUND

With increased cure, childhood cancer survivors are reaching adulthood and seeking employment. Host, disease and treatment risk factors may contribute to inability to attain or maintain employment.

PROCEDURE

The prevalence and risk factors for unemployment were evaluated using self-reported employment history in 10,399 childhood cancer survivors and 3,083 siblings >/= age 18 in the Childhood Cancer Survivor Study (CCSS).

RESULTS

Among survivors, 5.6% reported unemployment, compared with 1.2% of siblings (odds ratio [OR] 3.7; 95% confidence interval [CI] 2.6, 5.1). Increased risks were observed within all cancer diagnoses. In multivariate analysis, diagnosis of central nervous system (CNS) tumor (OR 1.5; 95% CI 1.1, 2.1), bone cancer (OR 1.5; 95% CI 1.0, 2.1), treatment with >/=30 Gy cranial radiotherapy (OR 4.0; 95% CI 2.9, 5.5), female gender (OR 1.4; 95% CI 1.2, 1.7) and age < 4 years at diagnosis (OR 1.4; 95% CI 1.1, 1.8) increased risk. Diagnosis of CNS or bone tumor or cranial radiotherapy >/=30 Gy remained significant after adjusting for treatment, medical late effects, age and gender. Risk of unemployment decreased with attained age (OR((year)) 0.89; 95% CI 0.87, 0.91).

CONCLUSIONS

Compared to siblings, adult childhood cancer survivors are at increased risk for unemployment with highest risk defined by diagnosis, treatment and demographic factors.

Health-status of adult survivors of childhood cancer: a large-scale population-based study from the British Childhood Cancer Survivor Study

The purpose of this study was to investigate the effect of childhood cancer and its treatment on self-reported health-status in 10,189 adult survivors of childhood cancer in Britain. Age- and sex-adjusted scores on the SF-36 Mental and Physical Component Summary scales (MCS, PCS, respectively) were compared between survivors and UK norms, and between subgroups of survivors, by multiple regression. Survivors had comparable scores to UK-norms on the MCS scale (difference (D) = -0.1, 99% CI: -0.5, 0.3). The difference in scores between survivors and UK-norms on the PCS scale varied by age (p(heterogeneity) < 0.001). Young survivors (16-19 years) scored similarly to UK-norms (D = 0.5, (-1.1, 2.2), whereas the age groups of 25 and older scored statistically and clinically significantly below UK-norms (all p-values < 0.0001), with Ds ranging between -2.3 (-3.5, -1.2) and -3.7 (-5.0, -2.4). Survivors of central nervous system (CNS) and bone tumors scored significantly (p-value at all ages <0.003) below UK-norms on the PCS scale. Specifically, these survivors were substantially more limited in specific daily activities such as, for example, walking a mile (40, 63%, respectively) when compared to UK-norms (16%). In conclusion, childhood cancer survivors rate their mental health broadly similarly to those in the general population. Survivors of CNS and bone tumors report their physical health-status to be importantly below population norms. Although self-reported physical health is at least as good as in the general population among young survivors, this study suggests that perceived physical health declines more rapidly over time than in the general population.

The effects of response bias on self-reported quality of life among childhood cancer survivors

BACKGROUND

Several studies of long-term adjustment in childhood cancer survivors (CCS) report very positive outcomes, while other studies find significant adjustment problems. These inconsistencies have prompted some investigators to suggest survivors may be biased responders, prone to underreporting on self-report measures. This study tested the hypothesis that CCS are elevated on self-deception response bias (SDRB), and that SDRB is associated with higher ratings of quality-of-life (QOL).

METHODS

One hundred and seven adult (mean age = 31.85) survivors of childhood cancers completed a demographic questionnaire, Short Form-12 (SF-12), Functional Assessment of Cancer Therapy-General (FACT-G), and Self-Deception Enhancement scale (SDE), an SDRB measure.

RESULTS

Survivors' QOL scores were similar to normative groups, but they evidenced much higher levels of response bias. SDE scores were significantly correlated with the FACT-G, and SF-12 Mental Health (but not Physical Health) scores even after accounting for demographic and treatment-related variables.

CONCLUSIONS

CCS show a biased response style, indicating a systematic tendency to deny difficulties on QOL measures. This may complicate QOL studies by inflating survivors' reports of their socio-emotional functioning. Understanding how response bias develops may help us learn more about cancer survivors' adaptation to illness, and the effects of the illness experience on their perceptions of QOL.

Young survivors of malignant bone tumours in the extremities: a comparative study of quality of life, fatigue and mental distress

PURPOSE

The purpose of the study was to compare the quality of life (QoL), fatigue and mental distress in survivors of malignant extremity bone tumours (EBT survivors) with age and gender-matched survivors of Hodgkin's disease (HD survivors) and testicular cancer (TC survivors) as well as normative samples from the general population.

PATIENTS AND METHODS

Five years or more after end of treatment, 75 EBT survivors were mailed a questionnaire containing Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale, the Fatigue Questionnaire and questions about demography. Fifty-eight EBT survivors responded. TC survivors, HD survivors and normative samples (NORMs) had earlier on filled in the same questionnaire. For EBT survivors, gender and age-matched controls were randomly selected among TC survivors, HD survivors and NORMs.

RESULTS

No significant differences in the fatigue or mental distress scores were observed between the survivor groups. The EBT survivors had significantly higher fatigue scores and lower depression scores than NORMs and significantly lower scores on all physical dimensions of QoL than TC survivors, HD survivors and NORMs. In multivariate analysis, a low level of education and lack of employment were significantly associated with caseness of mental distress. Older age at survey, female gender, being an EBT survivor and lack of employment were associated with caseness on the SF-36 Physical Component Summary Scale.

CONCLUSION

At long-term follow-up, EBT survivors did not show impaired mental health or fatigue at the group level, although their post-treatment status was characterised by reduced QoL dimensions on physical function compared to TC survivors, HD survivors and NORMs.

Treatment late effects in long-term survivors of pediatric sarcoma

PURPOSE

To assess health and musculoskeletal function in survivors of pediatric sarcomas.

PATIENTS AND METHODS

Thirty-two individuals treated for Ewing sarcoma family of tumors (ESFT), rhabdomyosarcoma (RMS), or non-rhabdomyosarcoma soft tissue sarcomas (NR-STS) with multi-modality therapy were enrolled on this cross-sectional study. Median age at the time of therapy was 15.4 years (range 7.1-34.2), median age at the time of analysis was 37.4 years (17.5-55.4), and median duration of time elapsed from completion of therapy was 17.3 years (2.9-32.6). Participants underwent assessments of musculoskeletal functioning, cardiac function, metabolic and lipid analyses, renal and gonadal function, and psychological evaluation.

RESULTS

This cohort of sarcoma survivors shows expected locoregional limitations in function of the area affected by sarcoma, and impaired global musculoskeletal functioning as evidenced by limited endurance and limited overall activity levels. The cohort also demonstrated substantial rates of cardiac dysfunction, elevated body fat index, hyperlipidemia, chronic psychological distress, and infertility in men (76%) and premature menopause (49%) in women.

CONCLUSION

Sarcoma survivors demonstrate diminished locoregional and global musculoskeletal functioning which likely limit occupational opportunities and socioeconomic health. In addition, the combination of diminished cardiac reserve, limited activity levels, and lipid dysregulation in sarcoma survivors suggests that this population is at increased risk for cardiovascular disease, even many years following completion of sarcoma therapy. Sarcoma survivors may benefit from life long follow-up for cardiovascular disease and from occupational counseling upon completion of therapy.

Persistent psychological distress in long-term survivors of pediatric sarcoma: the experience at a single institution

BACKGROUND

The long-term psychological impact of pediatric sarcoma is largely unknown. As part of a cross-sectional study examining the late effects of pediatric sarcoma therapy, we examined whether psychological distress or posttraumatic stress symptoms are present in an adult cohort of pediatric sarcoma survivors.

METHOD

Thirty-four patients participated in the study, an average of 17 years after their treatment ended, each completing the SCID module for Posttraumatic Stress Disorder, Impact of Events Scale, Brief Symptom Inventory (BSI) and a questionnaire assessing sociodemographic variables and psychosocial issues.

RESULTS

Significant persistent psychological distress characterized this cohort of patients. Seventy-seven percent scored in the clinical range on the BSI. Twelve percent met diagnostic criteria for PTSD. Current psychological distress was associated with intrusive thoughts and avoidant behaviors, male gender, employment, difficulty readjusting to work/school after treatment, and enduring worries about health. No differences were found based on age, presence of metastatic disease or time since diagnosis.

CONCLUSIONS

This is the first report of a clinical evaluation of psychological distress in a cohort of pediatric sarcoma survivors treated with intensive multimodal cancer therapy. The results suggest that survivors of pediatric sarcoma might be at high risk for adverse psychological outcomes. Appropriate interventions are proposed.

Adult survivors of childhood cancer and unemployment: A metaanalysis

A range of late effects is associated with the survival of childhood cancer, including problems with employment. The purpose of this metaanalysis was to assess the risk of unemployment of adult survivors of childhood cancer compared with healthy controls and to explore prognostic factors. A literature search of studies published between 1966 and January 2006 was conducted using the databases of MedLine, CINAHL, EMBASE, ClinPSYCH, PsycINFO, and OSHROM. The authors synthesized data using a random effects model. A total of 34 articles was found, in which 40 original empirical studies were reported, 24 of which were controlled studies. Survivors of childhood cancer were nearly twice as likely to be unemployed than healthy controls (odds ratio [OR] 1.85, 95% confidence interval [95% CI], 1.27-2.69). Survivors of central nervous system (CNS) and brain tumors were nearly 5 times more likely to be unemployed (OR 4.74, 95% CI, 1.21-18.65), whereas the risks for survivors of blood or bone cancers were elevated but not found to be statistically significant (OR 1.42, 95% CI, 0.79-2.55; OR 1.97, 95% CI, 0.88-4.40, respectively). No increased risk was found for survivors of other or mixed diagnoses (OR 0.97, 95% CI, 0.27-3.53). Furthermore, survivors in the U.S. had an overall 3-fold risk (OR 3.24, 95% CI, 2.16-4.86) of becoming unemployed, whereas no such risk was found for European survivors (OR 1.00, 95% CI, 0.58-1.70). Apart from type of diagnosis and country, predictors of unemployment were younger age, lower education or intelligence quotient, female gender, motor impairment or epilepsy, and radiotherapy. Adult survivors of childhood cancer are at risk of unemployment, especially the subgroup of survivors of CNS and brain tumors. Interventions to enhance participation in work life should be developed and evaluated.

Progress in the development of childhood cancer therapy

Despite the continuous improvement of cancer treatment protocols, altered testicular function and infertility frequently represent major adverse effects of oncologic treatments. Thus, strong efforts are needed to avoid or at least to reduce these complications that are particularly relevant in young men without offspring. Furthermore in the last years, concerns have been raised about the possible mutagenic effect of chemotherapy on sperm. Alkylating agents are frequently and successfully used in the treatment of paediatric tumors despite their well-known gonadotoxic effect. While gonadal toxicity of cyclophosphamide has been well demonstrated, little and conflicting data are reported about the effects on testicular function of ifosfamide. The aim of this study was to compare long-term effects of ifosfamide versus cyclophosphamide based therapies, on testicular function, fertility and sperm aneuploidies in a group of 33 young males survivors of childhood cancer. Patients who had received cyclophosphamide showed a severe gonadal failure characterized by reduced testicular size, very low sperm count and some degree of Leydig cell impairment. On the contrary, in subjects who had received ifosfamide all parameters of testicular function including sperm aneuploidies were in the normal range, despite of different dose, protocol of infusion and pubertal stage at treatment. In conclusion, our results confirm data of literature reporting the high gonadal toxicity of cyclophosphamide and suggest that ifosfamide treatment seems to be safer for testicular function and fertility.

Quality of life of patients treated during childhood for a bone tumor: assessment by the Child Health Questionnaire

To determine which factors impact on quality of life of patients with bone tumor, we used the Children Health Questionnaire French version. Thirty-seven patients (25 males, 19 osteosarcoma, 18 Ewing sarcoma) were studied. At assessment, median age was 15 years, median follow-up was 4 years. Mean scores were 60, 81, 76, 74, 70, 87 for general health, physical functioning, pain, mental health, self-esteem, and family activity, respectively. Lower results were observed for mental health in girls, for physical functioning, and self-esteem in patients with endoprosthesis, and for family activity and pain in patients who had relapsed.

Twenty-year follow-up of osteosarcoma of the extremity treated with adjuvant chemotherapy

We have updated the results of an adjuvant chemotherapy study of 106 patients with osteosarcoma of the extremities published 17 years ago, treated by surgery followed by adjuvant chemotherapy with vincristine (VCR), methotrexate (MTX) and doxorubicin (ADM), between 1980-1983, and followed-up for at least 20 years (20-23 years). In comparison with the results reported 17 years ago with a median follow-up of 38 months (range: 27-66), this updated study showed 24 more deaths, 9 more relapses and 3 second malignancies. Consequently, event-free survival (EFS) and overall survival (OS) are significantly lower compared to the previous study with a 3-year follow up (EFS 38% vs 53%; OS 43.8% vs 67%). We conclude that osteosarcoma patients treated with chemotherapy are at risk of late adverse events. Protracted medical follow-up and long-term updated results are useful to identify, at an early stage, late relapses and late treatment-related complications.

Quality of life, self-esteem and worries in young adult survivors of childhood cancer

This study assessed quality of life, self-esteem and worries in young adult survivors of childhood cancer compared to a group of young adults with no history of cancer. The impact of demographic, medical and treatment factors and self-esteem on survivors' quality of life and worries was studied. Participants were 400 long-term survivors (LTS) of childhood cancer (age range 16-49 years, 45% female) who had completed treatment an average of 16 years previously and 560 persons (age range 16-53 years, 55% female) with no history of cancer. All participants completed the MOS-24 (Medical Outcome Study Scale), a Worry questionnaire consisting of three scales (cancer-specific concerns, general health concerns, present and future concerns), and the Rosenberg Self-Esteem Scale. Small to moderate differences were found in mean MOS-24 scores between the LTS group and controls (range effect sizes -0.36-0.22). No significant difference was found in the mean self-esteem scores between LTS and controls. Female LTS had more cancer-specific concerns than male LTS. In several related areas of general health, self-image and dying, the LTS group reported less worries than controls, but LTS worried significantly more about their fertility, getting/changing a job and obtaining insurance's. Multiple linear regression analysis revealed that female gender, unemployment, severe late effects/health problems and a low self-esteem were predictors of worse quality of life in survivors. In addition, age at follow-up, unemployment, years since completion of therapy and a low self-esteem were associated with a higher degree of survivors' worries. Quality of life and the level of self-esteem in LTS of childhood cancer is not different from their peers. Although many LTS worried not more or even less about health issues than their peers, they often are concerned about some present and future concerns. The investigated factors could explain poor quality of life and worries only to a limited extent. Further research exploring determinants and indices of quality of life and worries in LTS is warranted.

Late events occurring five years or more after successful therapy for childhood rhabdomyosarcoma: a report from the Soft Tissue Sarcoma Committee of the Children's Oncology Group

The aim of our study was to describe late failures in children who initially survived event-free five years from a diagnosis of rhabdomyosarcoma. Charts of children enrolled in the Intergroup Rhabdomyosarcoma Study Group (IRSG) trials III, IV pilot and IV (1984-1997) who survived five years event-free and subsequently experienced an adverse event (disease recurrence, second malignant neoplasm or death from other causes) were reviewed. Of the 2534 enrolled patients, 1160 were event-free at five years and 48 subsequently experienced a late event. The estimated 10-year event rate for the 1160 patients who were alive and event-free at five years was 9% (95% Confidence Interval (CI) 5%, 13%). Patients with both advanced disease (Group III/IV) and large primary tumours at diagnosis (> 5 cm) were at the highest risk for late events (19%; 95% CI 8%, 30%). Late events after successful treatment for rhabdomyosarcoma occur in 9%. Those with advanced disease and large primary tumours have the highest risk of late events.

Posttraumatic stress symptoms in adult survivors of childhood cancer

BACKGROUND

Previous research suggests that posttraumatic stress disorder (PTSD) is present in survivors of childhood cancer. The aim of the current study was to explore posttraumatic stress symptoms in a sample of young adult survivors of childhood cancer. In addition, the impact of demographic, medical and treatment factors on survivors' posttraumatic stress symptoms was studied.

PROCEDURE

Participants were 500 long-term survivors of childhood cancer. The median age at follow-up was 24 years (age range, 16- 49 years, 47% female). To assess symptoms of posttraumatic stress, all participants completed the Impact of Event Scale (IES), a self-report instrument consisting of two subscales, intrusion and avoidance.

RESULTS

Twelve percent of this sample of adult survivors of childhood cancer had scores in the severe range, indicating they are unable to cope with the impact of their disease and need professional help. Twenty percent of the female survivors had scores in the severe range as compared with 6% of the male survivors. Linear regression models revealed that being female, unemployed, a lower educational level, type of diagnosis and severe late effects/health problems were associated with posttraumatic stress symptoms.

CONCLUSIONS

The results indicate that, although the proportion of survivors reporting symptoms is well within the proportions found in the general population, a substantial subset of survivors report symptoms of posttraumatic stress. This finding supports the outcomes reported previously that diagnosis and treatment for childhood cancer may have significant long-term effects, which are manifested in symptoms of posttraumatic stress. The investigated factors could explain posttraumatic stress symptoms only to a limited extent. Further research exploring symptoms of posttraumatic stress in childhood cancer survivors in more detail is clearly warranted. From a clinical perspective, health care providers must pay attention to these symptoms during evaluations in the follow-up clinic. Early identification and treatment of PTSD symptoms can enhance the quality of life for survivors of childhood cancer.

Life after cancer in childhood: social adjustment and educational and vocational status of young-adult survivors

PURPOSE

To evaluate the long-term social effect of illness and its treatment on young-adult survivors of pediatric cancer by addressing a selection of general social adjustment criteria.

METHODS

In a cross-sectional case-control study, 30 young-adult survivors of childhood cancer were compared with (1). controls with no history of serious illness, matched by sex, age, and geographic area of residence, and (2). general population norms on the subject of educational and vocational factors, habitation, family/partner relationships, parenthood, and leisure activities.

RESULTS

The educational status of survivors was similar to that of controls, although a smaller proportion of the patients expressed concrete plans for future vocational or educational advancement. Survivors had less frequently entered higher education compared with general population norms. A longer duration of treatment was related to a lower estimated socioeconomic level, and poor psychological coping with the illness experience was associated with the fact that they were still living with their parents, a shorter education, and a lower socioeconomic level.

CONCLUSIONS

The social, vocational, and educational adjustment of relapse-free survivors from childhood cancer appears as only moderately, if at all, negatively affected by the illness and treatment history. However, the treatment intensity and particularly the survivors' coping with their illness experience may influence their ability to achieve long-term social goals. These findings suggest that special attention should be given to matters concerning education and partner relationships at long-term follow-up of pediatric cancer patients.

Marriage and fertility in long-term survivors of high grade osteosarcoma

One hundred fifteen patients with high grade osteosarcoma were treated at our hospital between 1976 and 1995. Of these, 45 patients still surviving and disease free for more than 5 years since the conclusion of treatment were enrolled as the subjects. The marriage proportion (number of married persons/number of all persons) and fertility proportion (number of persons having an offspring/number of married persons) of these 45 patients were investigated. The marriage proportion of male patients was 20.8% (5/24), whereas that of female patients was 76.2% (16/21). The marriage proportion in male patients was dramatically lower than that in female patients (p = 0.0003). The marriage proportion in male patients was significantly lower than that in brothers of the patients (p = 0.0223). In female patients, the treatment of osteosarcoma had no influence on marriage, whereas in male patients it had a great influence on marriage. The fertility proportion in married patients was 76.2% (16/21) and that in siblings of the patients was 81.0% (17/21). A total of 18 offspring were born to married patients. These offspring had no birth defects or congenital anomalies. The chemotherapy used in the treatment of osteosarcoma had little influence on the fertility of patients or the health of their offspring.

Long-term outcome for patients with non-metastatic Ewing's sarcoma treated with adjuvant and neoadjuvant chemotherapies. 402 patients treated at Rizzoli between 1972 and 1992

We evaluated the long-term results obtained in 402 patients with non-metastatic Ewing's sarcoma (ES) of the bone treated in a single institution with adjuvant and neoadjuvant chemotherapies between 1972 and 1992. Multivariate analyses showed male gender, age older than 14 years, high serum lactate dehydrogenase (LDH) level, axial location of the tumour, use of radiotherapy alone as a local treatment, and poor histological response to chemotherapy, to be independent, adverse prognostic factors for event-free survival (EFS). At a mean follow-up of about 18 years (10-30 years), 177 patients (44.0%) remained continuously free of disease, 2 died of doxorubicin-induced cardiotoxicity and 8 developed a second neoplasm (5 died, and 3 are alive and free of disease). 215 patients relapsed with metastases and/or local recurrence: 14 are alive and free of disease, 1 is alive with uncontrolled disease, and 200 died. The overall survival (OS) at real follow-ups of 5-, 10-, 15- and 20-years was 57.2, 49.3, 44.9 and 38.4%, respectively. We conclude that since local or systemic relapses, treatment-complications and second malignancies are more common after 5 years or more from the beginning of treatment; a long-term follow-up is mandatory for patients with ES.

Synovial sarcoma after chemotherapy for osteosarcoma: a case report

A 23-year-old man had eight cycles of adjuvant chemotherapy including doxorubicin, cisplatin, methotrexate, and ifosfamide and radical surgery for biopsy-proved osteosarcoma of the right fibular shaft. Two years after the initial diagnosis, he noticed a mass in the medial aspect of his right knee. Magnetic resonance imaging scans revealed a soft tissue tumor measuring 2 x 2 cm in the pericapsular region of the right knee. Histologically, this soft tissue tumor was composed of spindle cells with occasional atypical mitoses and without matrix formation. Immunohistochemically, the tumor cells were positive for vimentin, cytokeratin, and epithelial membrane antigen, and negative for alpha smooth muscle actin. A fusion gene, SYT-SSX was detected with reverse transcription-polymerase chain reaction. From the results, the secondary tumor was diagnosed as a synovial sarcoma. The current case of double sarcomas is rare. Both sarcomas were diagnosed accurately using immunohistochemical and molecular procedures. This case suggests a positive association between a second tumor and chemotherapy including intraarterial perfusion of doxorubicin.

Multiple primary malignancies in osteosarcoma patients. Incidence and predictive value of osteosarcoma subtype for cancer syndromes related with osteosarcoma

The overall incidence of osteosarcoma is low. However, the occurrence of osteosarcoma in a setting of multiple primary tumours is not infrequent, although population-based incidence numbers are unknown. The occurrence of osteosarcoma and other malignancies is frequently related to treatment, and can also be the result of genetic predisposition as in patients with retinoblastoma, Li-Fraumeni syndrome, Werner syndrome and Rothmund-Thomson syndrome. The aim of our study is to establish the incidence of osteosarcoma associated with other malignancies in a populationwide study and to find out if these osteosarcomas have a specific subtype, that could draw attention to a genetic predisposition to malignancy. A list of all patients registered in the Dutch National Pathology Register, named PALGA, with a diagnosis of osteosarcoma between 1975 and May 2000 was retrieved. All patients with another malignancy besides osteosarcoma were selected. All patients registered in the same period with a tonsillectomy served as a control for the occurrence of malignancy in a normal population. In a second step, only osteosarcoma patients with a history of retinoblastoma or a malignancy before the age of 46 years, since these are most probable to have a hereditary cancer syndrome, were retained for further analysis. The osteosarcomas were subtyped as common, chondroblastic, fibroblastic, teleangiectatic, anaplastic, osteoclast-rich or small cell. As a control for osteosarcoma subtypes the data of 570 patients entered in two studies from the European Osteosarcoma Intergroup (EORTC/MRC) were used. Of all 938 patients registered with the diagnosis of osteosarcoma, 66 had a history of multiple primary tumours. Four patients had a surface osteosarcoma, three an extraskeletal osteosarcoma and 59 had intramedullar high-grade osteosarcoma. Of this last group, one patient was known with Rothmund-Thomson syndrome, one had retinoblastoma and 30 had their malignancies before the age of 46. Of these 32 patients, 17 had osteosarcoma of the long bones. Especially women seem to be more susceptible for the development of multiple primaries. In nine patients, the histological subtype could be assessed by revision of available histological slides. All of these patients had an osteosarcoma subtype other than common as opposed to 29% in the control group of the European Osteosarcoma Intergroup. It is concluded that although the incidence of osteosarcoma is low, the occurrence of another malignancy in osteosarcoma patients is higher than in the normal population. Specifically, osteosarcoma patients have a relative risk of 2.4 (95% confidence interval 1.88-3.07) to develop another malignancy. A noncommon subtype of osteosarcoma should draw attention to a possible genetic predisposition of the patient involved.

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.

Restoration of ovarian function after chemotherapy for osteosarcoma

AIM

To evaluate ovarian function after modern intensive multi-agent chemotherapy for osteosarcoma given during childhood or adolescence.

METHODS

After discontinuation of treatment, 10 female osteosarcoma survivors were followed up for 1.5-14 (median 4.6) years. Their age at diagnosis was a median of 12.9 (range 6-15) years and at the last follow up 18.6 (range 16-22). The main follow up included recording of their pubertal and menstrual status and of sex hormone determinations.

RESULTS

Prior to diagnosis, 5/10 had had their menarche, and one had it while on therapy. At discontinuation of chemotherapy, ovarian function had severely deteriorated; none of the girls experienced regular menstrual cycles. However, during follow up, significant restoration of ovarian function was evident. At the last follow up, 9/10 patients were menstruating spontaneously. During follow up, four patients, three of whom had received high doses of alkylating agents, presented with clear hypergonadotrophism with high FSH levels (14.4-132 IU/l). Three of these four patients initiated menstruation after their gonadotrophin levels normalised.

CONCLUSIONS

The modern multi-agent chemotherapy applied for osteosarcoma impairs ovarian function. Normalisation of ovarian function is common, even in cases with severe hypergonadotrophic hypogonadism, but may only occur after several years off chemotherapy. Regular assessment of ovarian function and cautious use of hormone replacement therapy are important in patients with chemotherapy induced gonadal damage.

Second malignant neoplasms in long-term survivors of osteosarcoma: Memorial Sloan-Kettering Cancer Center Experience

BACKGROUND

The authors investigated the incidence and relative risk of secondary malignant neoplasms in long-term survivors of osteosarcoma.

METHODS

A comprehensive list of 509 patients with primary osteosarcoma treated at our institution between February 1973 and March 2000 was identified. All study patients received chemotherapy and/or surgery on one of six different protocols (T4, 5, 7, 10, 12, and CCG-7921/POG-9351). Chemotherapy was scheduled for up to 40 weeks with some variations in the actual treatment period and consisted of various combinations of the following agents: high-dose methotrexate, doxorubicin, bleomycin, cyclophosphamide, dactinomycin, vincristine, cisplatin, and ifosfamide.

RESULTS

Secondary malignant neoplasms (SMN) occurred in 14 of 509 patients. Only one had pulmonary metastasis at diagnosis and subsequent multiple recurrences that required thoracotomies and further modification of the chemotherapy regimen. The median age at diagnosis for osteosarcoma was 16.6 years (range, 3.1-74.4 years). The median follow-up was 5.2 years (range, 0.1-25.0 years). The time interval from diagnosis of the primary osteosarcoma to the development of SMN was 1.3-13.1 years (median, 5.5; 95% confidence interval [CI], 3.6-9.6). The most common SMN occurred in the central nervous system (n = 4): anaplastic glioma, meningioma, high-grade glioma, and maxillary astrocytoma. There were two cases of acute myeloid leukemia and one case each of myelodysplastic syndrome, non-Hodgkin lymphoma, high-grade pleomorphic sarcoma, leiomyosarcoma, fibrosarcoma, breast carcinoma, and mucoepidermoid carcinoma. The overall 5 and 10-year cumulative incidences of SMNs were 1.4% +/- 1.1% and 3.1% +/- 1.8%. The standardized incidence ratio was 4.6 (95% CI, 2.53-7.78, P = 0.00001) for the cohort and 3.64 (95% CI, 1.82-6.52, P = 0.0007) when patients with a history of retinoblastoma or Rothmund-Thomson syndrome were excluded.

CONCLUSIONS

The overall incidence of secondary malignancies in long-term survivors of osteosarcoma was significantly higher than the expected incidence of cancer in the general population. However, the standardized incidence ratios were much lower than those reported for Hodgkin disease and retinoblastoma. Although additional follow-up is warranted, the successes of current treatment regimens consisting of intensive, high-dose chemotherapy in combination with topoisomerase II inhibitors outweigh the risks.

Outcome of lower extremity malignancy survivors treated with transfemoral amputation

OBJECTIVE

To determine outcomes of surviving patients who underwent transfemoral amputation as part of treatment for lower extremity malignancy at a mean 15 years postoperatively, with a minimum 2-year follow-up.

DESIGN

Retrospective, case control.

SETTING

Tertiary care university medical center.

PATIENTS

Thirty-five of 38 consecutively admitted patients free of metastatic disease managed with transfemoral amputation as part of treatment of a lower extremity bone and/or soft tissue malignancy between 1966 and 1997 at 1 institution. The control group included 35 age- and gender-matched subjects recruited from the local driver's license office.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Musculoskeletal Function Assessment (MFA), Short Form-12 General Health Status Survey (SF-12), physical performance battery, cost, and demographic data.

RESULTS

Controls showed superior scores as measured by the MFA (P < .0001), the physical component summary of the SF-12 (P = .0002), and the physical performance battery (P < .0001), but had inferior scores on the mental component summary of the SF-12 (P < .0001). With the numbers available, no differences were found between study and control subjects in terms of employment rate (P = .51), education level (P = .66), income level (P =.44), marital status (P = .79), incidence of self-reported health problems (P = .14), and alcohol (P =.42) and tobacco (P = .82) use. Ten patients were included in the cost analysis; the mean cost to obtain and maintain a lower extremity prosthesis was $4225 per year (range, 623 dollars-8517 dollars).

CONCLUSIONS

Although the decrease in physical performance was anticipated in the study group, the group differed very little from the control population in terms of employment, education level, income, marital and home status, incidence of self-reported health problems, incidence of self-reported depression, and alcohol and tobacco use. Also, the long-term cost of maintaining a lower extremity prosthesis is noted.

Second malignancies after ewing tumor treatment in 690 patients from a cooperative German/Austrian/Dutch study

BACKGROUND

Ewing tumor treatment involves high cumulative doses of alkylating agents and topoisomerase inhibitors, drugs capable of inducing second cancers. We analyzed the second cancer risk in a large cohort of consistently treated patients.

PATIENTS AND METHODS

Six hundred ninety Ewing tumor patients were treated between 1992 and 1999 with local therapy and vincristine. doxorubicin, ifosfamide and/or cyclophosphamide, and antinomycin D, with or without etoposide as a randomized question. Second cancer incidences were estimated by competing risk analyses; standardized incidence ratios (SIR) in comparison to registry data were compiled.

RESULTS

After a median observation time of 56 months (32 months for survivors), 6 of 690 patients had developed second cancers: MDS/AML, two, ALL/NHL, two, squamous cell carcinoma, one, liposarcoma, one. SIR were increased 20-30 fold in comparison to the general population. The cumulative second cancer risk five years after diagnosis of the Ewing tumor was 0.0093 for the total group, zero for patients without etoposide, and 0.0118 with etoposide. Additional phase II high-dose therapy increased the risk to 0.0398 after five years.

CONCLUSIONS

The second cancder risk observed was in the range to be expected in cancer survivors. High-dose therapy, and less markedly, etoposide, may contribute to the overall second cancer risk.

Rehabilitation for limb salvage patients: kinesiological parameters and psychological assessment

Osteosarcoma is the most frequently occurring primary malignant tumor of bone, especially in adolescence. Treatment involves either limb salvage surgery or amputation with neoadjuvant chemotherapy. This review article discusses the current treatment modalities for osteosarcoma and also compares the gait patterns and psychosocial profiles of patients treated with either limb salvage surgery or amputation for osteosarcoma. Contemporary orthopedic literature on therapeutic options for osteosarcoma patients is reviewed. Background information on the basic principles of kinesiology, with emphasis on studies of gait pattern differences among patients treated with limb salvage versus amputation, is presented. Finally, several studies of the psychologic profiles of patients after these two procedures for osteosarcoma are reviewed. Trends in contemporary orthopedic literature suggest that functional outcomes, in terms of kinesiologic parameters, are comparable for patients treated with either limb salvage or amputation. Both sets of patients reported quality-of-life problems, including difficulty retaining health insurance and finding appropriate employment, social isolation, and poor self-esteem. The management of patients with osteosarcoma includes not only an individualized surgical plan for each patient but also includes awareness of the patients' psychologic and social needs after surgery.

Thyroid carcinoma after successful treatment of osteosarcoma: a report of three patients

We report three cases of papillary thyroid carcinoma occurring after successful treatment of osteosarcoma. Only one of the three patients received radiation therapy (to the chest) as part of the primary treatment of osteosarcoma. The onset of thyroid carcinoma occurred between 8 and 16 years from the cessation of osteosarcoma therapy. All patients are alive and disease-free from both malignancies. Whereas the association between osteosarcoma and thyroid carcinoma has not previously been recognized, there have been five case reports of these two entities occurring in the same patient. Three of these cases occurred in patients with Werner syndrome. None of the patients reported here had physical stigmata of Werner syndrome or a family history consistent with a hereditary cancer syndrome. Thyroid carcinoma occurs infrequently in patients with osteosarcoma, but in view of the rarity of these two disorders, this association may represent an inherited predisposition to these malignancies.
