The decline in
childhood cancer
mortality in Italy from 1955 to 1980 has been evaluated through (1) comparison of age-specific and age-standardized (0-14 years) rates for the periods 1955-1960 and 1979-1980 and (2) computation of expected numbers of deaths by application of the age-specific rates for the period 1955-1960 to the population structure of subsequent periods. Certified mortality fell by 35% for leukaemias, 90% for
Hodgkin's disease
, 30% for non-
Hodgkin
's lymphomas, 40% for bone sarcomas, 30% for kidney (Wilms') tumours, 65% for retinoblastoma. No clear trend was reported for other neoplasms, including neuroblastoma. About 300 cancer deaths per year were avoided in the period 1979-1980 compared with the expected number based on the 1955-1960 rates (170 for leukaemias alone). Although clearly encouraging, these trends are substantially less favourable than those from several other developed countries. It is therefore likely that several dozen other deaths from
childhood cancer
could be avoided each year through earlier (or more accurate) application of effective therapies, particularly for neoplasms requiring radiotherapy or surgical treatment.

Time trends and differentials in cancer incidence in the five Nordic countries, Denmark, Finland, Iceland, Norway and Sweden, were investigated, using material collected by the cancer registries in each country. The incidence at all sites combined and at 23 anatomical sites was studied by age, birth cohort and time period. The maximum lengths of the trends were used for each country. In Denmark the material comprised all the tumours diagnosed in 1943-1980, in Finland and Norway those diagnosed in 1953-1980, in Iceland those diagnosed in 1955-1980, and in Sweden those diagnosed in 1958-1980. For males the age-adjusted cancer incidence rates at all sites combined were highest in Denmark and Finland, and lowest in Sweden and Norway. In females the incidence was highest in Denmark and Iceland, and lowest in Finland. The rates increased slightly for both sexes. For cancer of the pancreas,
Hodgkin's disease
, acute leukaemia and
childhood cancer
(all sites combined) the rates in all the Nordic countries were similar every year. For cancers of the stomach, colon, breast, corpus uteri, ovary, prostate, testis, urinary bladder, melanoma of the skin and non-
Hodgkin
's lymphomas the trends were similar but on different levels. For cancers of the larynx and lung in males the rates in Finland decreased during the 1970s, whereas the rates were increasing in the other Nordic countries. For cancer of the rectum, the trend showed a decrease in Denmark but an increase in the other Nordic countries. For lip cancer the rate in Sweden was almost constant over time, but in Denmark, Finland and Norway a decrease occurred. For oesophageal cancer in males the rates decreased in Finland and Iceland in the 1970s, whereas in Denmark and Norway there was very little change, and in Sweden there was an increase in the rates. For cancer of the cervix uteri the rates started to decrease in Denmark, Finland, Iceland and Sweden in the mid-1960s, but in Norway not until some ten years later. The differentials between the countries were largest for cancers of the testis and thyroid, in which the highest incidence was five to six times as large as the lowest. For testicular cancer the rate was the highest in Denmark, for thyroid cancer in Iceland. For both of these cancers the rate was the lowest in Finland. Melanoma of the skin was the cancer with the most rapid increase in incidence with time in all the Nordic countries.(ABSTRACT TRUNCATED AT 400 WORDS)

In order to assess the effects of various cancer treatments on neuropsychological functioning, 74 long-term survivors of
childhood cancer
were examined. A comprehensive battery of tests was administered to two CNS treatment groups (irradiated and nonirradiated leukemia and lymphoma patients) and a control group (solid tumor and
Hodgkin disease
patients receiving no CNS treatment). The CNS-irradiated group obtained lower scores than the other two groups, with significant differences in visual-motor and fine motor skills, spatial memory, and arithmetic achievement resulting in significant differences in IQ scores (VIQ, PIQ, FSIQ). The results are discussed in relation to: (1) the effects of CNS irradiation on cognitive development; (2) the specificity of these effects; and (3) the relationship of age at diagnosis to treatment effects. It is concluded that although there is a general lowering of scores after CNS irradiation, the effect is most pronounced for nonlanguage skills. Age at diagnosis was less important than the type of treatment, with CNS irradiation reducing performance regardless of when cancer was diagnosed. There were indications that children with any type of cancer diagnosed before age 5 years are more likely to have some cognitive difficulties.

The reported relationship of radiation exposure and thyroid carcinoma stimulated this retrospective study of 298 patients treated at St. Jude Children's Hospital with radiation therapy to the neck for
childhood cancer
to identify patients who developed subsequent thyroid abnormalities. This series includes 153 patients with
Hodgkin's disease
, 95 with acute lymphocytic leukemia, 28 with lymphoepithelioma, and 22 with miscellaneous tumors. Inclusion in the study required 5 years of disease-free survival following therapy for their original tumor, which included thyroid irradiation. Follow-up has been 100%. Most patients also received chemotherapy. Seventeen patients were found to have decreased thyroid reserve with normal levels of free triiodothyroxine (T3) or free thyroxin, (T4) and an elevated level of thyroid-stimulating hormone (TSH). In nine patients hypothyroidism developed, with decreased T3 or T4 levels and an elevated level of TSH. One hyperthyroid patient was identified. Two patients had thyroiditis, and seven had thyroid neoplasms: (carcinoma in two, adenoma in two, colloid nodule in one, and undiagnosed nodules in two). This survey has demonstrated an increased incidence of thyroid dysfunction and thyroid neoplasia when compared to the general population. The importance of long-term follow-up for thyroid disease is emphasized in patients who have received thyroid irradiation. The possible role of subclinical hypothyroidism with TSH elevation coupled with radiation damage to the thyroid gland as a model for the development of neoplastic disease is discussed.

Trends in
childhood cancer
death rates in Italy from 1955 to 1978 were analyzed. All cancer age-standardized mortality below age 15 fell about 20%, with a clear downward trend since the early 1970's. Declines were evident for leukemias (-25%),
Hodgkin's disease
(-56%), non-
Hodgkin
's lymphomas (-27%), kidney cancer (-25%), retinoblastoma (-50%), and bone sarcomas (-31%), for a total number of about 200-250 fewer deaths per year in the late 1970's compared to the expected values using rates of the 1950's. The observed fall was apparently confined within the first age group considered (0-4 years), but the age-specific patterns of trend were partly influenced by simple postponement of some deaths to older age groups. Comparisons with similar data in other developed countries suggest that, although there has undoubtedly been some progress, there is still wide scope for further reduction in
childhood cancer
mortality in Italy, simply through more rational use of currently available diagnostic and therapeutic knowledge.

Between 1973 and 1983, eight children who had undergone successful multimodal management of malignant tumors developed secondary thyroid neoplasms. The primary tumors were acute lymphocytic leukemia in three, Wilms' tumor in two, and
Hodgkin's disease
, rhabdomyosarcoma, and ganglioneuroblastoma in one each. During this period, 174 long-term survivors with these five diagnoses were enrolled in our tumor registry, yielding a 4.6% incidence of secondary thyroid neoplasms. All eight patients received both radiation and chemotherapy. The mean radiation dose was 2,700 r with a calculated thyroid dose of 2,140 r (range, 5 to 4,200 r). Age of diagnosis of the primary tumors ranged from 1 to 8 2/12 years (mean, 5 years), and the latent period between treatment and development of the thyroid lesions averaged 6 1/2 years. Thyroid neoplasms presented at an average age of 11 4/12 years. Five patients developed solitary adenomas, one presented with multiple adenomas, and two had follicular carcinoma with regional lymph node metastases. Although thyroid neoplasms are rare in childhood, clinically apparent thyroid tumors have been observed in up to 2.5% of children following radiation exposure (mean follow-up, 24 years). The reported latent period before the development of thyroid neoplasms in irradiated patients is at least 10 years, with the peak incidence occurring 20 to 25 years after exposure. This study documents a 4.6% incidence of subsequent thyroid neoplasms in
pediatric cancer
patients within a relatively short follow-up period (mean, 11 years). These thyroid tumors occurred at an earlier age (mean, 11.5 years) and with a shorter latent period (mean, 6.5 years) than would be predicted from previous studies.(ABSTRACT TRUNCATED AT 250 WORDS)

Cancer mortality among children in the United States, 1950 through 1979, as evaluated by death certificate diagnoses, revealed dramatic declines primarily in the second half of the 30-year interval. The numbers of deaths of persons younger than 15 years, 1965 through 1979, as compared with the number expected at 1950 rates, fell 50% for leukemia, 32% for non-Hodgkin's lymphoma, 80% for
Hodgkin's disease
, 50% for bone sarcoma, 68% for kidney cancer, and 31% for all other cancer. There were 17,411 fewer deaths from
childhood cancer
from 1965 through 1979 than expected at the 1950 rate. Leukemia mortality declined by 8,073 deaths and kidney tumor mortality by 2,393. In data subsequently received for 1980, the decline in rates persisted for leukemia and non-Hodgkin's lymphoma, but the rates for the other four cancer categories seem to have reached a plateau. The reduction in mortality is attributed to improved therapy.

The true survival rates for the various forms of
childhood cancer
are best determined from a population-based study rather than from the results of clinical trials. Population-based survival rates have been calculated for four periods between 1956 and 1980 in Queensland. There was a significant improvement in survival for children who developed cancer after 1973 compared with those diagnosed before this date. There has however been no significant improvement in the survival rate for
childhood cancer
overall, or for acute lymphoblastic leukaemia since 1973. Over the 25 year period significant trends in survival rates were seen in acute lymphoblastic leukaemia, non-Hodgkin's lymphoma,
Hodgkin's disease
, Wilms' tumour, medulloblastoma, and retinoblastoma. No such trend was seen for acute non-lymphoblastic leukaemia, neuroblastoma, rhabdomyosarcoma, juvenile or anaplastic astrocytoma, brain stem glioma, histiocytosis X, or bone tumours. There is a need for continuing research into better methods of treatment of
childhood cancer

Improved survival in
childhood cancer
resulting from advances in therapy is frequently associated with long-term morbidity, including the potential for second malignancy. In a review of the literature in the English language, we found 33 cases of acute lymphocytic leukemia (ALL) followed by a second neoplasm. Second tumors in this group of patients with ALL include seven cases of histiocytic medullary reticulosis, four cases of
Hodgkin's disease
, nine cases of acute myelocytic leukemia, four cases of chronic myelocytic leukemia, and nine cases of solid tumors. The appearance of subsequent malignancies may be related to a combination of therapy-induced immunosuppression, a direct carcinogenic effect resulting from therapy, and/or constitutional factors. Physicians should be alert to the possibility of subsequent malignant neoplasms in survivors of cancer.

Second malignant neoplasms (SMN) in individuals who survived
childhood cancer
have been reported with increasing frequency during the last decades. The overall probability of developing second malignancy for children treated for cancer was estimated at about 2-5% at 25 years. In children, the tumors most often associated with the development of SMN are retinoblastoma and
Hodgkin's disease
. We report two cases of unusual second tumors in two patients cured of lymphoid malignancy: one boy cured of acute lymphoblastic leukemia developed mediastinal ganglioneuroma nine years later and one girl had gastric carcinoma seven years after
Hodgkin's disease
. Both developed a tumor in nonirradiated areas. Gastric carcinoma and ganglioneuroma are not reported as recurrent SMN in survivors after
childhood cancer
, with one single case of gastric carcinoma and one of ganglioneuroblastoma having been reported as second tumor in survivors after
childhood cancer
.
