Challenges After Curative Treatment for Childhood Cancer and Long-Term Follow up of Survivors

Guidelines for the diagnosis, management, and surveillance of cancer patients have evolved with the single goal of improving patient care based on established data when available, or in the absence of firm data, on the standard practices of those with broad experience in actual hands-on patient care. Two initiatives intended to disseminate information to cardio-oncologists, were discussed in this session: the first, from the American Society of Clinical Oncology was focused on available data and the confidence level of that data; the second, from The European Society of Cardiology was a position paper. Interestingly, notwithstanding the somewhat different focus, there is considerable agreement between these two initiatives. Nevertheless, guidelines my not be applicable to all afflicted patients, and may raise questions as to when deviations from published standards should be considered. Such deviations may result in allegations of failure to meet standards of care or legal liability.

Urological survivorship issues encompass an area that may potentially be overlooked after treatment of childhood cancer in adolescent boys and young men. Side effects of cancer therapy may include subsequent development of erectile dysfunction (ED), hypogonadism, and infertility in adulthood.

The purpose of this review is to focus on the etiology and prevalence of the range of sexual and gonadal dysfunction in adolescent boys and young men who are cancer survivors, while discussing current recommendations for evaluation and treatment.

We performed a literature review of articles evaluating hypogonadism, sexual dysfunction, ED, and infertility in young men cancer survivors.

There is compelling evidence that significant survivorship issues are faced by boys entering adulthood after completing cancer therapy.

Overall, young men cancer survivors are much more likely to report symptoms of sexual dysfunction than the general population of men. These patients can develop ED due to physiologic and psychological changes that take place with diagnosis of a malignancy and subsequent treatment. Primary hypogonadism can arise due to pelvic radiation or chemotherapy, and central hypogonadism may arise from pituitary insufficiency after brain radiation or surgery. Infertility develops from direct damage to the Sertoli cells and germinal epithelium from radiotherapy or chemotherapy. Cancer survivors who are men should therefore be screened for these important urological survivorship issues, although exact surveillance strategies remain unclear.

Urological survivorship issues including ED, hypogonadism, and infertility are common among cancer survivors and result in significant morbidity. Due to the medical complexity of cancer survivorship, the population of adolescent and young adult survivors would benefit from a network of multidisciplinary survivorship experts to aid the transition into adulthood. Improved research efforts may help to clarify risk factors and to develop enhanced strategies for evaluation and treatment.

To describe how nurses can use risk reduction and health promotion activities to facilitate surveillance of late effects and secondary cancers in long-term cancer survivors.

Literature review on survivorship, nursing practice, cancer prevention, and survivorship; articles published in peer-reviewed scientific journals; and Web-based or professional organization resources.

Appropriate participation in screening activities, early detection of cancer, and further advances in treatment have contributed to the rise in cancer survivors. A demand for nurses with clinical experience and competence in survivorship care will follow.

Oncology nurses have an essential role in providing safe and high-quality care throughout the survivorship experience, which can contribute to better long-term outcomes.

Evaluar actitudes, creencias y conocimientos de los profesionales médicos de Atención Primaria acerca del seguimiento de los supervivientes de cáncer pediátrico (SCP) y divulgar el Programa de Largo Seguimiento de Supervivientes de Cáncer Pediátrico en la Región de Murcia (PLASESCAP-MUR).

Estudio transversal descriptivo mediante cuestionario estructurado y autocumplimentado. Se enviaron cuestionarios a todos los profesionales médicos de Atención Primaria del Área de Salud 1 del Servicio Murciano de Salud.

Tasa de respuesta del 58% (100/172). El 71 y el 22% eran médicos de familia y pediatras, respectivamente. El 49% atendió algún SCP en los últimos 5 años. El 84% refiere que nunca o pocas veces recibió un informe detallado de evaluación global del superviviente. Más del 75% encuentran bastante o muy útiles el acceso a información detallada de largo seguimiento. El 95% prefiere atender a los supervivientes conjuntamente con consulta de largo seguimiento. Un 80% considera que mejorando la calidad ambiental del entorno podría disminuir la morbimortalidad de los supervivientes. Se encontró una relación estadísticamente significativa entre años practicando medicina y percepción de importancia de algunos factores medioambientales.

Para el largo seguimiento de los SCP parece importante aumentar la capacitación de los profesionales sanitarios de Atención Primaria y la información detallada a través de un plan personalizado de largo seguimiento de cada superviviente. PLASESCAP-MUR proporciona un seguimiento integrativo a los supervivientes de cáncer pediátrico en un modelo de atención compartida entre la Unidad de Largo Seguimiento y Atención Primaria.

To assess attitudes, beliefs and knowledge of primary medical care professionals as regards the follow-up of Childhood Cancer Survivors (CCS) and the introduction of a Long-Term Follow-Up Program for Childhood Cancer Survivors in the Region of Murcia (PLASESCAP-MUR).

Descriptive cross-sectional study using a structured, self-administered questionnaire. These questionnaires were sent to all primary medical care professionals in Murcia Health District 1.

Response rate of 58% (100/172), with 71% and 22% being family physicians and pediatricians, respectively, of whom 49% provided medical care to a CCS in the last 5 years, with 84% reporting that they never or rarely received a detailed report of overall assessment of the survivor. More than 75% found that access to detailed follow-up information was quite or very useful; 95% prefer to consult experts when providing medical care to survivors, and 80% believe that improving the quality of the environment may decrease the morbidity and mortality of the survivors. A statistically significant relationship was found between the length of practicing medicine and the perception of the importance of environmental factors.

It seems to be important to increase the training of primary care professionals for the long-term follow-up of CCS, as well as having the detailed information through a personalized long-term follow-up of each survivor. PLASESCAP-MUR offers an integrated follow-up to CCS in a model of shared care between Long Term Monitoring Units and Primary Care Units.

Survivors of childhood cancer treated with anthracycline chemotherapy or chest radiation are at an increased risk of developing congestive heart failure. In this population, congestive heart failure is well recognised as a progressive disorder, with a variable period of asymptomatic cardiomyopathy that precedes signs and symptoms. As a result, several clinical practice guidelines have been developed independently to help with detection and treatment of asymptomatic cardiomyopathy. These guidelines differ with regards to definitions of at-risk populations, surveillance modality and frequency, and recommendations for interventions. Differences between these guidelines could hinder the effective implementation of these recommendations. We report on the results of an international collaboration to harmonise existing cardiomyopathy surveillance recommendations using an evidence-based approach that relied on standardised definitions for outcomes of interest and transparent presentation of the quality of the evidence. The resultant recommendations were graded according to the quality of the evidence and the potential benefit gained from early detection and intervention.

To determine the feasibility of fertility preservation in adolescent males with cancer.

Large multicenter retrospective study of male patients ≤20 years from 23 centers of a national network of sperm banks over a 34-year period.

Sperm banks.

A total of 4,345 boys and young men aged 11 to 20 years.

Age, cancer diagnosis, feasibility of sperm banking, and sperm parameters.

Description of patients, and success of their fertility preservation.

We observed a mean yearly increase in referred patients of 9.5% (95% confidence interval, 9.1%–9.8%) between 1973 and 2007. Over the study period, the percentage of younger cancer patients who banked their sperm increased, especially in the 11–14 year age group, rising from 1% in 1986 to 9% in 2006. We found that 4,314 patients attempted to produce a semen sample, 4,004 succeeded, and sperm was banked for 3,616. The mean total sperm count was 61.75 × 10⁶ for the 11–14 year age group, and 138.81 × 10⁶ for the 18–20 year age group. It was noteworthy that intercenter variations in practices involving young patients seeking to preserve their fertility before cancer therapy were observed within this national network.

Our results emphasize the need for decisive changes in public health policy to facilitate the access to reproductive health-care for young cancer patients.
