Ultrasonography for thyroid screening after head and neck irradiation in childhood cancer survivors.

We prospectively used ultrasonography to detect thyroid abnormalities in 96 long-term survivors of childhood cancer, who received head and neck radiation therapy at a median age of 8.9 years. The median time interval since irradiation was 10.8 years (range 5.6-22.8 years). Most survivors of leukemia received 24 Gy cranial irradiation for central nervous system prophylaxis; patients with solid tumors received between 20 and 66 Gy (median 37.5 Gy). The total evaluation included clinical history, physical examination, thyroid function tests, and thyroid ultrasonography; radionuclide scans were performed in patients whose abnormalities persisted on subsequent ultrasound exams. Clinical history and physical examination revealed thyroid abnormalities in 14 patients (15%), but ultrasound detected abnormalities in 42 patients (44%). These findings included inhomogeneity (n = 29), cysts (n = 15), and nodules (n = 22) and occurred in nearly half of patients treated with 15 Gy or more directly to the thyroid gland. Radionuclide scans confirmed the presence of thyroid nodules in 13 of 15 patients with ultrasonographic evidence of nodules. Six patients had thyroid neoplasia, including one case of papillary carcinoma. All patients with neoplasia had nodules demonstrated on ultrasonography. Our experience suggests that in childhood cancer survivors, ultrasonography is a sensitive, affordable, and noninvasive means of detecting subtle parenchymal abnormalities. We recommend thyroid ultrasonography for childhood cancer survivors who received head and neck irradiation. A baseline study should be obtained within 1 year of completion of therapy. The frequency of subsequent examinations should be based on the radiation dose and the patients age at the time of irradiation.

Health status and health‐related quality of life in long‐term adult survivors of pediatric solid tumors

We have examined the influence of selected factors (gender, marital status, socio‐economic status, co‐morbid conditions, access to medical care, age at diagnosis, intensity of therapy and time since diagnosis) on subsequent health status and health‐related quality of life (HRQL) of long‐term survivors of pediatric solid tumors. Two hundred and twenty individuals who had survived a pediatric solid tumor 15 years or longer completed telephone and written assessments of their current status. Health status was assessed using the Late Effects of Normal Tissues toxicity scale. HRQL was investigated using the Ferrans and Powers Quality of Life Index–Cancer (QLIC) and the EORTC Quality of Life Questionnaire C30 (QLQ‐C30). Results indicated that health status and HRQL were better in survivors treated with low‐intensity therapy. One hundred and thirty respondents (59.1%) reported at least 1 serious toxicity. Dyspnea and fatigue were commonly reported in survivors of Hodgkins disease. Correlational analyses showed that predictors of health status included socio‐economic status, marital status and the presence of co‐morbid factors. Mean HRQL scores for the 4 domains of the Ferrans and Powers QLIC and the functional scales of the EORTC QLQ‐C30 indicated that most of the survivors were experiencing moderately good to excellent HRQL. One‐third of survivors reported that their history of cancer had an adverse impact on their current financial status. Prediction models constructed for 3 of the domains from the 2 HRQL instruments are presented (health and functioning, global HRQL and financial impact). Within these 3 models, consistent predictors of HRQL outcomes included health status, presence of dyspnea or pain, marital status and socio‐economic status. Int. J.

The experience of South American mothers who have a child being treated for malignancy in the United States.

This phenomenological study examined the experience of South American mothers who brought their children to the United States for cancer treatment. Five mothers were interviewed twice about their subjective experiences. Data were analyzed using Colaizzis method of phenomenology. Thirty-two significant statements were grouped into eight themes. The South American mothers brought their children to the United States in hopes of finding effective treatment, illustrating the major theme of our findings that no effort or sacrifice was too great to save their childrens lives. The diagnosis of cancer had an overwhelming impact on the child and the family. This was made worse by the uncertainty of treatment outcome. Although the decision to come disrupted family life and caused economic and cultural hardship, it was uniformly believed to have been the right decision. The greatest challenges experienced by the mothers were language difficulties and the constant preoccupation with the childs illness. Through faith and a variety of coping strategies, these South American mothers succeeded in adapting. They transcended life disruption and focused on the critical goal of restoring their childs health. Central to their experience is that everything humanly possible be done to preserve the life of their child.

Skeletal scintigraphy in patients with bilateral retinoblastoma

One hundred‐seventeen radionuclide bone scans were performed on 46 patients with bilateral retinoblastoma between diagnosis and 19 years from diagnosis for the purpose of detecting skeletal metastases or other malignant neoplasms of bone that might develop in this group of patients at high risk for a second malignancy. Only one child, who had been symptomatic for 1.5 years, had a scan positive for metastasis at diagnosis. Scans in three additional children became positive (in one after the development of metastatic disease involving bone and soft tissue but not bone marrow 2 years after the diagnosis of retinoblastoma, and in two others after the development of osteosarcoma at 10.5 and 16 years from the diagnosis of retinoblastoma). Our data indicate that bone scans should not remain as part of the initial staging of patients with bilateral retinoblastoma unless there is clinical or pathologic evidence of extraocular disease at diagnosis. The performance of skeletal scintigraphy also is not warranted, with the expectation of diagnosing a second malignant neoplasm (namely osteosarcoma).

Late outcomes of adult survivors of childhood non-Hodgkin lymphoma: A report from the St. Jude Lifetime Cohort Study

Survivors of childhood non‐Hodgkin lymphoma (NHL) are at increased risk for chronic health conditions. The objective of this study was to characterize health conditions, neurocognitive function, and physical performance among a clinically evaluated cohort of 200 childhood NHL survivors.

Phase I clinical and pharmacokinetic study of bisantrene in refractory pediatric solid tumors

SummaryFourteen patients with pediatric malignant solid tumors, median age 15 years, received 22 courses of bisantrene in a Phase I study. Dosage escalations ranged from 10 to 120 mg/m2 daily for 5 consecutive days. Toxicity included myelosuppression and phlebitis. A sensitive (detection limit of 2 ng/ml) and specific HPLC method was developed to quantitate bisantrene in patients plasma and urine. Peak plasma concentrations at the end of 60 minute infusions ranged from 568 ng/ml at 10 mg/m2 to 6800 ng/ml at the 100 mg/m2 dosage. The elimination half life (T 1/2β) averaged about 10 hours but increased to 20 hours in a patient with liver disease. Only 2.4–10% of the bisantrene dose was eliminated in the urine suggesting that the liver may be the major route of elimination for this antineoplastic anthracene derivative.

Outcome for patients with constitutional 13q chromosomal abnormalities and retinoblastoma.

The outcomes for five patients with retinoblastoma and constitutional chromosomal abnormalities involving the long arm of chromosome 13 are reported. All patients demonstrated developmental delay and mental retardation. Four of these patients are alive 23, 21, 15, and 1 year from diagnosis; one died of pneumonia with septicemia. Each of the four survivors has, with aging, shown hypotonia, mutism, contractures, and inability to function independently.

Life Satisfaction in Adult Survivors of Childhood Brain Tumors

Adult survivors of childhood brain tumors experience multiple, significant, lifelong deficits as a consequence of their malignancy and therapy. Current survivorship literature documents the substantial impact such impairments have on survivors’ physical health and quality of life. Psychosocial reports detail educational, cognitive, and emotional limitations characterizing survivors as especially fragile, often incompetent, and unreliable in evaluating their circumstances. Anecdotal data suggest some survivors report life experiences similar to those of healthy controls. The aim of our investigation was to determine whether life satisfaction in adult survivors of childhood brain tumors differs from that of healthy controls and to identify potential predictors of life satisfaction in survivors. This cross-sectional study compared 78 brain tumor survivors with population-based matched controls. Chi-square tests, t tests, and linear regression models were used to investigate patterns of life satisfaction and identify potential correlates. Results indicated that life satisfaction of adult survivors of childhood brain tumors was similar to that of healthy controls. Survivors’ general health expectations emerged as the primary correlate of life satisfaction. Understanding life satisfaction as an important variable will optimize the design of strategies to enhance participation in follow-up care, reduce suffering, and optimize quality of life in this vulnerable population.
