Dr. Grayson (February 21, p. 445) asks about changes in vital statistics of 3rd world populations as they develop. Of African populations, those in Johannesburg and other large South African cities, while still in transition, have now reached a relatively high level of sophistication. Their health pattern is likely to be that of other African countries as they prosper. The (IMR) infant mortality rate of blacks in Soweto, Johannesburg, is about 40/1000 live births, although nearer 30 in the regularly employed elite. This figure is similar to that for blacks in New York in 1965 and for class 5 persons in the United Kingdom. Small-town dwellers have higher IMRs and in rural areas the rates are higher still although they are decreasing everywhere. Family size is decreasing; in urban areas the average family has 3-4 children and the elite have 2-3. In Johannesburg during the 1960s, the birth rate was about 40/1000 and it is now 25. While the rate is higher in rural areas, it is falling. In the very young, gastroenteritis with or without malnutrition is still the leading cause of sickness and death in both urban and rural areas. Rates are however decreasing. Deficiency diseases, especially pellagra, remain a health problem in some areas. Tuberculosis still continues to be a major hazard although it is being dealt with. With the rise in socioeconomic status and associated changes in diet and lifestyle, obesity, especially in urban areas and especially among women, is becoming very prominent. Hypertension is more common and is the leading cause of natural death among urban dwellers. The toll from coronary heart disease and noninfective bowel disease remains inexplicably low, but diabetes is only somewhat less prevalent than it is among whites. Changes in cancar pattern and rates are slight; however, esophageal cancer in men and cervical cancer in women are the main causes of concern in the urban centers and some rural areas. Rising alcohol consumption is a major problem with its ramifications in pancreatic, liver, and heart problems. Cigarette smoking is now as common as among whites. Because of low rates for most degenerative diseases, blacks have, at middle age, a life expectancy exceeding that of whites. As sections of the 3rd world population prosper, the IMR decreases enormously as does family size. However, infections and malnutrition among the very young and tuberculosis in older groups remain important problems. Among adults, rises occur in some degenerative diseases but not in others, and diseases linked with hypertension and alcohol consumption have become formidably common, as they have in other developing and developed countries.

Menopausal disorders coincide with the onset of luteal insufficiency and the resulting relative hyperestrogenism. At this stage the risks to be assessed are mainly related to a worsening of the menstrual syndrome (heaviness of the legs, abdominal distention, water retention, mastodynia, depressive syndrome), cycle changes, or various genital types of hemorrhage requiring investigation for detection of a possible fibroma, hyperplasia, endometriosis, or genital cancer. Once the menopause is settled a reduction in estrogen levels comes with reactive increases in FSM and LM levels, and the principal risk is the development of a cancer. The role of endogenous (obesity, diabetes, Stein-Leventhal, adenomatous hyperplasia) or exogenous (prolonged estrogen therapy alone) estrogens has to be evaluated in endometrial cancer. Cancer of the vulva also appears to be more frequent in menopausal women (natural or artificial), as well as cervical cancer and cancer of the breast. There is an apparent increase in cardiovascular risks in untreated menopausal women, but this is still discussed, as to the benefits of estrogen therapy.

Breast cancer among Japanese females was characterized by a relatively low incidence and good prognosis. But recently its morbidity is increasing and its biological behavior is changing. The chronological changes and prospective features of breast cancer among Japanese females are follows: 1. Increase of morbidity and mortality 2. Increase of the ratio of poorly differentiated carcinoma and decrease of well differentiated carcinoma 3. Increase of the incidence of lobular carcinoma 4. Increase of the case of the aged females Above items show that breast cancer among Japanese females is becoming westernizing. The case-control study on "breast cancer occurrence and obesity" shows that an obesity of the aged is a significant high risk factor for breast cancer occurrence. There fore, it would be effective that the prevention of overweight at the postmenopausal women to reduce the breast cancer occurrence. The chronological rise of overall 10-year survival rate of operated breast cancer is caused by increasing the ratio of early stage cases. Suggesting an importance of regular self-examination of the breast. Furthermore, it is important to establish an adjuvant therapy without causing side effect for curatively operated cases. Concerning the cancer of the uterus among Japanese females, the chronological occurrence rate of endometrial cancer is increasing, while the death rate of cervical cancer is decreasing.

There are currently numerous well-woman clinics in Britain which emphasize a specific aspect of health care, including cervical cancer screening (134 centers), family planning (142 centers), antenatal care (162 clinics), and venereal disease control (15 clinics). However, care provided in these clinics is fragmentary and excludes certain population groups from coverage. For example, cervical cancer smears are largely sought by upper class women under age 35, although this cancer has a higher incidence among older women from the lower social classes. Similarly, family planning clinics are not attracting women at highest risk of repeat abortion. Antenatal clinics, although effective in reducing perinatal and maternal mortality, exclude women beyond the childbearing years. At present, there are less than 10 comprehensive well-woman clinics in Britain. However, an estimated 17 million women could benefit from such a service, especially if cervical cytology screening was absorbed within it. A comprehensive clinic could focus on medical problems common to women, including menopause, frigidity, child abuse, obesity, thyroid disease, and depression. Omissions created by fragmented care, such as failure to test for conditions like anemia, could be avoided. The Manchester well-woman clinic, set up in 1981, provides an example of the role such clinics could play. The clinic is targeted at women who rarely see a general practitioner, e.g., poor, infertile, older women. Its emphasis is on the prevention and early detection of disease. Treatment is limited to self-help support groups and discussions with staff; however, new attendees are screened by a physician and nurse. 99% of attendees were found to have at least 1 medical problem. 2/3 of these problems, including breast problems, vaginal discharge, menopause problems, depression, and headache, were not already being treated. This experience suggests that there is an untapped need for such a facility, especially among women between menopause and old age.

Cancer prevention as related to the problem of cervical and endometrial cancer involves a great number of factors that are considered contributory to the development of neoplasms in the uterus. Lifestyles encouraging the development of cervical cancer are different from those encouraging endometrial cancer. Cancer of the cervix is a disease of the inner city. It is seen in those staring intercourse in their teens, having multiple partners, having many children, and coming from the low socioeconomic groups. Semen and herpes virus II may have an adverse effect on immature cells, but there are no hard data to confirm these roles. Cancer of the endometrium is a disease of suburbia. The American Cancer Society estimates that there will be 38,000 new cases of endometrial carcinoma in 1980, making it the most common female genital cancer. Women at highest risk for later carcinoma of the endometrium are those who have obesity, diabetes, infertility, irregular menses and failure of ovulation, adenomatous hyperplasia, and/or prolonged estrogen administration. For both cervical and endometrial cancers, it is possible to identify the high-risk patient, to detect changes at an early stage, and, by instituting appropriate therapy, to prevent a more serious problem. It is obvious that prevention, detection, and treatment are all closely intertwined. This paper identifies the patient at high risk and makes suggestions for correcting any imbalance that may predipose to the development of invasive cancer.

A European School of Oncology Advisory Group has reviewed the European Code Against Cancer after its initial use over a 6-year period. With minor modifications, the original ten recommendations were found to be adequate, although it was agreed that an Annex was necessary to explain the scientific evidence supporting each point, and is presented herewith. Tobacco smoking clearly remains the most important cause of cancer, and now it can be quantified better than ever before. It is also clear that it is never too late to stop smoking: stopping even in middle age, prior to the onset of serious illness has a beneficial effect on life expectancy. Alcohol drinking is an important cause of cancer, and yet modest consumption levels protect against cardiovascular disease mortality. The optimal strategy seems to be a consumption not exceeding 2-3 drinks per day, although this limit may be lower for women. Increased consumption of fruits and vegetables, reduction in consumption of fatty foods, reduction of obesity and increased physical activity can all be recommended to reduce cancer risk. Exposure to excessive sunlight remains a problem which should be limited. Control of occupational cancer is a three-way partnership: legislation identifies and limits exposure to known carcinogens, employers enact the legislation and workers should respect the measures introduced. There are a number of signs and symptoms which may lead to cancer being diagnosed earlier, and patients with these should be referred to a doctor. For women, participation in organised programmes of cervical cancer and breast cancer (after 50 years of age) should lead to a reduction in mortality from these forms of cancer. The key element is organised programmes, where quality control and quality assurance are in force. These revised recommendations are the result of an agreement following advice, review and dialogue with cancer experts throughout Europe. They were approved by the European Community Cancer Experts at their meeting in Bonn on 28-29 November 1994. Their implementation by the European population should greatly reduce cancer incidence and mortality.

Endometrial carcinoma remains the most common invasive gynecologic malignancy. Increased longevity is associated with an increased incidence of endometrial carcinoma (EC) in elderly women. While recent studies have looked at aging and its relation to ovarian, breast, and cervical cancer, few have focused on EC in the growing elderly population. This study analyzed 35 histologic specimens of EC in women 75-92 years of age. Findings revealed that only 23% of the tumors were Stage I, G1. The majority (77%) were deeply invasive or of advanced stage (IC-IV). These were G2, G3, or "virulent" types of nonendometrioid EC (undifferentiated, clear cell, uterine serous papillary, and squamous cell carcinoma). Fifty-seven percent of tumors were endometrioid, of which 9% were mixed, including a rare case of nongestational choriocarcinoma. The nonendometrioid tumors, compared to the endometrioid types, were more often high-stage tumors with vascular invasion. They were also more often associated with atrophic (vs hyperplastic) uninvolved endometrium. Clinical risk factors (nulliparity, obesity, estrogen replacement therapy) were assessed and correlated with the histologic findings. It was shown that tumors in the elderly were less likely to be estrogen-related. It was concluded that EC in this age group is more aggressive, histologically less differentiated, and often nonendometrioid compared with EC in the general population. The increased virulence of EC in the elderly may be related to the tumor's independence from hormonal factors, to the poorly understood but well-known diminished immunologic defense against cancer in general in elderly patients, and/or to the belated diagnosis of the disease in this population.

A set of new guidelines were formulated by an expert group meeting in Sweden organized by the pharmaceutical office during March 31-April 1, 1993. It contains various methods to avoid an undesired pregnancy and also advice about postcoital contraception. Among barrier methods, the condom is the only reversible method for men with a method failure of 2 and user failure of 10. It protects against gonorrhea, chlamydia, condyloma, herpes simplex, HIV, and hepatitis B. The diaphragm can be used with a spermicide and protects to a lesser degree against chlamydia, gonorrhea, and cervical cancer. The female condom is as effective as the condom. Among spermicides, nonoxynol-9 is not only effective against sperms but also against bacteria, viruses, and certain vaginal and cervical cells. The vaginal sponge is impregnated with nonoxynol-9 and is effective up to 24 hours. The copper IUD, with a method failure of less than 1, can cause profuse menstrual bleeding, dysmenorrhea, and endometritis-salpingitis. Hormonal methods include combination pills (2-phase and 3-phase pills) and gestagen methods (high dose with 150 mg of medroxyprogesterone acetate injection every 3 months and low-dose minipills with levonorgestrel, norethisterone, or lynestrol). Mechanisms of action concern combination pills, gestagen methods, minipills, Norplant, and Levonova. Drug cross reaction can reduce effectiveness. Side effects include bleeding and amenorrhea. Risk-benefit determination is based on health effects. Possible risks are associated with breast cancer, cervical cancer, blood pressure increase, venous thromboembolism, and heart infarction. Various phases of the reproductive age include young women, lactating women, and women in the later part of the reproductive age. Special groups include those who have experienced ectopic pregnancy, infections (candida, sexually transmitted diseases: chlamydia trachomatis, HIV infections), obesity, cardiovascular diseases, diabetes mellitus, tumors of the reproductive organs, liver diseases, migraine, epilepsy, surgery, and handicapped women. Postcoital contraception is used only in need, and methods for postcoital contraception include hormonal method and the copper IUD.

In order to evaluate the etiology, incidence of malignancy, clinical risk factors and the interval between menopause and the onset of abnormal vaginal bleeding in postmenopausal women, 381 cases with a complete medical history and available histologic findings were enrolled in this study at the National Taiwan University Hospital from 1989 to 1991. The results showed that 212 (55.6%) of these women had normal histologic findings and 83 (21.9%) had benign pathologic findings, whereas 14 (3.6%) had cervical intraepithelial neoplasia (CIN), 42 (11%) had endometrial hyperplasia, 19 (5%) had cervical cancer and 11 (2.9%) had endometrial cancer. Twenty-nine (7.6%) of the cases suffered from either CIN III or cervical cancer; this number was twice as high as those with endometrial atypical hyperplasia and endometrial cancer (n = 13, 3.4%). In addition, various risk factors, especially obesity, were found to be significantly correlated with malignancy. Fractional curettage should be performed for postmenopausal bleeding patients to ensure accurate diagnosis and correct management.

Cancer mortality rates for Aberdeen Area Indians exceed U.S. rates with lung cancer being the leading cause of cancer death. The Sioux Cancer Study, an ancillary study of the Strong Heart Study, investigated cancer and cancer risk factors among tribal members aged 45-74 in three Sioux tribes in North and South Dakota. An Indian-specific health risk appraisal was used to collect data and provide specific recommendations to participants. The high rates of smoking (56% for men and 48% for women) explain the high lung cancer mortality rates. Intensive smoking cessation and prevention programs will likely have the greatest impact in reducing preventable cancer deaths. More accessible cervical and breast cancer screening provided by female health care providers is needed to reduce preventable cancer deaths among Sioux women. Pap smear screening is an especially high priority since cervical cancer mortality is 4.4 times higher than U.S. rates, all races. Programs targeted to reduce obesity and excessive alcohol use will also likely reduce preventable cancer deaths associated with high rates of obesity, diabetes and binge drinking. Community-based cancer prevention and control programs tailored to the cancer risk factor profile of the community are the best strategy to reduce preventable cancer deaths in Indian communities.
