In 1977, a Cancer Control and Surveillance Unit was established by the South Australian government. The infrastructure of the Unit was the State's Cancer Registry which was established simultaneously. By 1990, approximately 70,000 invasive cancer cases had been notified to the Registry for a population which had increased from 1,287,550 in 1977 to 1,400,000. In 1990, 2940 cancers were notified in males and 2640 in females. The leading sites in males were the prostate, lung, colon and melanoma of the skin, while in females they were the breast, colon, melanoma of the skin and lung. An increase in age-standardised incidence rates for all cancer sites combined has been documented for the 1977-1990 period. The magnitude of the increase was 7% in males and 12% in females. Meanwhile, there were 1544 male cancer deaths and 1203 female cancer deaths in 1990. Amongst males, age-standardised mortality rates tended to decline in the 1980's, due largely to a reducing age-standardised incidence of lung cancer. By comparison, an increased lung cancer incidence in females contributed to an overall increase of 6% in the age-standardised mortality rate for cancers of all sites combined in this sex during the life of the Registry. During the period 1977-1990 there was a 55% increase in the number of new invasive cancers in males and females combined. Most of this increase can be attributed to the ageing of the South Australian population and to a much lesser degree to population growth. During the same period there was a concomitant increase in 43% in the number of deaths where the underlying cause of death was cancer. Case survival rates are found to be very similar in South Australia to those reported for the United States, with about 51% of cases surviving their cancers 5 years after diagnosis. 5-year survival rates for the diagnostic period, 1983-1990, were generally better than for 1977-1982. The evidence for improved survival was strongest for cancers of the oesophagus, colon, cervix, prostate and testes, and for low-grade and medium-grade lymphomas and chronic myeloid leukaemias. When case survival rates were calculated for childhood tumours, significant improvements were found for acute lymphatic leukaemias and non-Hodgkin lymphomas for the diagnostic period, 1983-1990, when compared with 1977-1982.

Data from the national tumor registry of Costa Rica for the years 1979-1983 have been used to calculate incidence rates for the major cancer sites by age, sex, urban-rural residence, and geographic region. Recent trends in mortality rates are also presented. Results are compared with data from elsewhere in Latin America, U.S.A., Europe, and Japan. Stomach cancer is the most frequent neoplasm in Costa Rica; although rates are declining, they are second only to those observed in Japan. There are marked variations in risk by region, suggesting important environmental influences in etiology. The cervix is the major female site; rates are declining in young women, probably due to the introduction of screening programs, although these do not seem to account for the geographic variations in invasive cancer incidence. Breast and prostate cancer show moderate rates, while those for colon and rectum cancer are low; increases in mortality rates for these sites are small, and involve mainly the older age groups. In contrast, rates of lung cancer are increasing dramatically in both sexes. In the childhood age group, very high incidence rates are observed for two neoplasms: Hodgkin's disease and acute lymphocytic leukemia.

Incidence of second primary cancers was evaluated in 7,127 women with invasive cancer of the cervix uteri, diagnosed between 1935 and 1978, and followed up to 38 years (average, 8.9 yr) in Connecticut. Among 5,997 women treated with radiation, 449 developed second primary cancers compared with 313 expected (relative risk = 1.4) on the basis of rates from the Connecticut Tumor Registry. Excess incidence was noticeable 15 years or more after radiotherapy and attributed mostly to cancers of sites in or near the radiation field, especially the bladder, kidneys, rectum, corpus uteri, and ovaries. No excess was found for these sites among the 1,130 nonirradiated women. The ratio of observed to expected cancers for these sites did not vary appreciably by age at irradiation. The data suggested that high-dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but, apparently, not leukemia, Hodgkin's disease, breast cancer, or colon cancer.

While the incidence of cancer is increasing among both children and adults, mortality rates have decreased for children, while they have increased for adults. Of children diagnosed with cancer today, 80% are predicted to be long-term survivors. Although there are differences between children and adults with respect to the tumor types, biology, and outcome, there are common lessons which we can learn from our children regarding the genetics of cancer, its management and treatment, and the importance of longitudinal studies of the survivors. Specific pediatric cancers, such as retinoblastoma, have led to the recognition of tumor suppressor genes, now also observed among adult tumors including sarcomas, breast, lung, and bladder cancer. The presence of the tumor suppressor gene provides an understanding for the incidence of second malignant tumors among patients with heritable diseases. Furthermore, cancer prone families, such as those with the Li-Fraumeni syndrome, also carry the p 53 tumor suppressor gene; the presence of which greatly increases the risk of developing invasive cancer. Childhood cancer is rare; it represents only 1% of the total US cancer problem. However, 53% of all children with cancer, but only 2% of all adults, are studied via the NCI cooperative group mechanism. For some specific childhood tumors such as rhabdomyosarcoma and Wilms' tumor, as many as 70-85% of all cases are managed via NCI sponsored trials. Essentially all pediatric cancer is treated by interdigitating radiation with surgical resection and systemic chemotherapy. This approach has contributed to high cure rates. Finally, our understanding of the late effects of being a cancer survivor have come from longitudinal studies of children. The most severe long-term effects related to radiation in childhood pertain to growth and development, infertility, and second malignant tumor induction. Here the children treated for Hodgkin's disease have taught us the dose and volume effects on axial skeletal and soft tissue growth. Infertility issues are also treatment-related and may often be obviated by using gonadal shielding. The risk of secondary leukemia is related to dose and class of specific chemotherapeutic agents administered; it is 5.5% among children receiving 6 cycles of MOPP. There is a 22-fold risk at 30 years of age of solid tumor induction following radiotherapy for children with Hodgkin's disease. These serious concerns have been offset by current therapeutic approaches of using lower doses and smaller volumes of radiation with fewer cycles of less toxic chemotherapeutic agents. Childhood cancer ranks high among number of person-years of potential life saved annually.(ABSTRACT TRUNCATED AT 400 WORDS)

HIV infection predisposes to several neoplastic conditions, especially non-Hodgkin lymphoma (NHL) and Kaposi's sarcoma (KS), and also intraepithelial cervical neoplasia (CIN) and anal neoplasia (AIN) (but not cervical or anal invasive cancer) and possibly seminoma. For neoplasias associated with oncogenic human viruses (ie, some NHL, CIN, AIN, and probably KS) the role of HIV is most probably linked to its immunosuppressive effect and interference with immune-mediated tumour surveillance. HIV-1, through its regulatory protein tat, might also have a direct promoting effect on KS lesions but it is not essential for their development. The increased frequency of Burkitt's lymphoma and Epstein-Barr-virus-negative large-cell lymphoma in AIDS patients, but not in immunosuppressed transplant patients, and the increased rate of testicular tumours in HIV-infected individuals remain unexplained and may indicate either a direct role for HIV or other cofactors.

In recent decades there has been parallel progress in the fields of cancer chemotherapy and reproductive medicine technology, which has led to increasing numbers of women surviving their malignancies, often with significant reproductive impairment, and a range of choices for the potential preservation of fertility, including storage of embryos, mature oocytes, immature oocytes or ovarian tissue. Although each of these procedures has specific relative advantages and disadvantages, there are no clear guidelines for selection of patients for such interventions. There are six distinct issues that should be considered before making any recommendations regarding the appropriateness of any of the range of measures aimed at enhancing the future reproductive capacity of the patient: (1) the risk of sterility with the proposed treatment program; (2) the overall prognosis for the patient; (3) the potential risks of delaying chemotherapy; (4) the impact of any future pregnancy upon the risk of tumour recurrence; (5) the impact of any required hormonal manipulation on the tumour itself; and (6) the possibility of tumour contamination of the harvested tissue. For illustrative purposes, it is reasonable to assume that the preservation of future fertility is likely to be a priority for women under the age of 40 years. Within this group in 1996 in the Australian State of Victoria (total population, approximately 4.6 million), there were 837 cases of cancer diagnosed (annual incidence rate, approximately 60 per 100,000 population). Of those afflicted, it is estimated that 10% were pre-pubertal, 38% were treated by potentially curative surgery alone, 15% had cancers of the reproductive tract, and 5% were treated with palliative intent. Thus the remaining 32% of patients with invasive cancer in this age group (267 per year) are potentially curable, and require initial treatment, including chemotherapy. These tumours comprise predominantly breast cancer (161 cases or 19%), sarcomas of bone and soft-tissue (32 cases or 4%), and the haematologic malignancies (Hodgkin's disease, non-Hodgkin's lymphomas, and the leukaemias, each approximately 25 cases or 3%). Consideration of procedures that may preserve future fertility would be appropriate in this group of patients. Current data relating to the six issues noted earlier using contemporary treatment programmes will be presented and discussed as they apply to each of these categories of patient. An understanding of the relative importance of each of these factors to patients with a range of malignancies will facilitate the safe and appropriate application of the available methods to maintain the possibility of future child-bearing.

Patients with HIV infection are at increased risk for developing Kaposi's sarcoma, non-Hodgkin's lymphoma, and several other cancers. The relative risks for the most common epithelial cancers in the general population--lung, breast, colon/rectum, stomach, liver, and prostate--are not increased substantially in people with AIDS, however. Accumulating data suggest that HIV-infected patients also are at increased risk for developing Hodgkin's lymphoma, cervical carcinoma in situ (CIS), other anogenital neoplasms (invasive cancer and CIS), leiomyosarcoma, and conjunctival squamous cell carcinoma. There is inconclusive evidence, however, with regard to HIV infection being associated with invasive cervical cancer, testicular seminoma, or hepatocellular carcinoma. Notably, other viral infections have been implicated in the etiology of many of these conditions. The introduction of highly active antiretroviral therapy (HAART) has decreased the incidence of AIDS-associated cancers in Western countries, but less than 1% of AIDS patients are receiving HAART in the HIV epicenter of sub-Saharan Africa. Further therapeutic advances that extend survival with HIV infection with varying reconstitution of immune competence may lead to additional alterations in cancer risk.

Between 1998 and 2000 an annual average of 3,303 cases of invasive cancer were registered in Navarre, 58% of them in men. If we except non melanoma skin tumours, the annual number of cases was 2,495, with gross incidence rates of 559 and 372 per 100,000 in men and women, and rates adjusted to the world population of 312 and 203 per 100,000 respectively. Amongst men, the four most frequently diagnosed tumoural localisations were the prostate, lung, colorectal and bladder, accounting for 57% of all cases. The most notable due to their frequency amongst women were tumours of the breast, colorectal, uterus body and ovary, accounting for 54% of all cases. With respect to the five year period from 1993 to 1997, the global incidence of cancer in the three year period from 1998 to 2000 has increased 4.2% in men and 7.4% in women. The incidence of lung cancer and non-Hodgkin lymphomas in both sexes and of breast cancer in women and prostate cancer in men are notable. There continues to be a fall in the incidence rates of stomach cancer in both sexes, following the tendency begun in the 1970s.

The Hmong represent a unique new Southeast Asian immigrant group to the U.S. Approximately 169,000 Hmong reside in the U.S., primarily in California, Minnesota, and Wisconsin. Previous studies of cancer in this population have indicated that Hmong experience an elevated risk of gastric, hepatic, cervical, and nasopharyngeal cancers and experience a reduced risk of breast, prostate, lung, and colorectal cancers. Approximately 65,000 Hmong live in California, where there has been a population-based cancer registry since 1988, and the authors used these data to calculate age-adjusted cancer incidence rates and to examine disease stage and tumor grade at diagnosis. Changes in rates during the period studied also were evaluated. These rates and proportions were compared with rates among the non-Hispanic white (NHW) and Asian/Pacific Islander (API) populations of California. Between 1988 and 2000, a total of 749 Hmong in California were diagnosed with invasive cancer, and the age-adjusted rate of cancer for the Hmong was 284 per 100,000 population, compared with 362.6 and 478 per 100,000 in the API and NHW populations, respectively. The age-adjusted incidence rates of cancer in the Hmong were elevated for hepatic, gastric, cervical, and nasopharyngeal cancers and for leukemia and non-Hodgkin lymphoma (NHL). Rates were lower in the Hmong for colorectal, lung, breast, and prostate cancers. For gastric cancer and lung cancer, age-adjusted rates increased between 1988 and 2000 in the Hmong, although breast cancer incidence declined. Cervical cancer incidence increased, rates of NHL were declining, and rates for colorectal cancer remained steady between 1988 and 2000. The Hmong experienced later disease stage at diagnosis than other API and generally poorer grade of disease at diagnosis. Hmong experienced lower overall invasive cancer incidence rates than API or NHW populations in California. However, they experienced higher rates of hepatic, gastric, cervical, and nasopharyngeal cancers; and, for most types of cancer, they were diagnosed in a later disease stage.

Treatment regimens for Hodgkin's disease (HD) that have included radiation to lymph node regions in the thorax have contributed to high rates of long-term disease-free survival. However, incidental radiation exposure of breast tissue in young women has significantly increased the risk of breast cancer compared to expected rates in the general population. After informing patients about risks associated with previous treatment of HD, we studied screening mammograms and call-back rates in women at increased risk for developing breast cancer at a younger age. We contacted by mail a cohort of 291 women between 25 and 55 years of age who had received thoracic irradiation before 35 years of age for HD with or without chemotherapy. Subjects were offered information about risks identified after HD therapy with questionnaires to assess response to this information. Ten patients refused participation, 93 did not respond, and 21 were excluded after they reported a prior diagnosis of invasive (1) or in situ (2) breast cancer. One hundred and sixty seven women received information about secondary breast cancer risk and were advised to initiate or maintain mammographic screening. Available mammograms were reviewed by two radiologists and classified according to the ACR BI-RADS Mammography Lexicon. Abnormal findings were correlated to pathology results from biopsies. One hundred and fifteen subjects reported that they obtained new mammograms during the period of the study. Ninety-nine were available for secondary review. Patients were studied an average of 16.9 years after HD treatment (Range: 4.5-32.5 years) at an average of 41 years of age (range 25-55 years). High density breast tissue was identified in 60% (60/99). Seventeen of the women (17.2%) were recalled for further imaging. This was more common in women with heterogeneously dense breast tissue. Seven of those recalled (41%) were advised to undergo biopsies that identified ductal carcinoma in situ (DCIS) in one and benign findings in the others. Among 16 women whose mammograms were unavailable for review, three were diagnosed with DCIS; two of these had microscopic evidence of invasive breast cancer. The four in situ or microinvasive cancers were diagnosed in the study participants at 25-40 years of age and from 5 to 23 years after HD therapy. Biopsies were performed because mammograms detected microcalcifications without palpable abnormality in three of these cases. Women who have had thoracic nodal irradiation for Hodgkin's disease have an increased risk of developing secondary breast cancer at an unusually young age. As expected in younger women, high density breast tissue was common on mammography, and the recall and biopsy rates were unusually high. However, early mammographic screening facilitated diagnosis of in situ and early invasive cancer in 3.5% of our subjects.
