The benefits of combined oral contraceptives are put into perspective, considering their effectiveness as a contraceptive, actual risks for breast, ovarian, endometrial and cervical cancer, and effects of reproductive and other body systems. Combined oral contraceptives are the best contraceptives available except for injectable progestogens, therefore they an reduce the risk of maternal mortality by at least 5 in nonsmoking western women, or over 100 in developing countries. No data are available on mortality risk of the presumed safer low-dose pills. Pills reduce ectopic pregnancy to virtually nil. They decrease the risk of
endometrial cancer
, and of ovarian cancer for up to 15 years after use. Although they protect against benign breast disease, both
fibrocystic disease
and fibroadenoma, which are risk factors for breast cancer, it is unsettled whether pills affect breast cancer incidence. Cervical cancer risk may be slightly higher. Functional ovarian cysts requiring surgery are cut about 10-fold; corpus luteum and follicular cysts are also reduced. Fibroids are decreased in proportion to duration of use. Pelvic inflammatory disease rates fall 50% during use. Chlamydial infections have not fallen in pill users, but it is not known whether sexual activity is a factor. Combined pills cut abnormal uterine bleeding by about half, reduce the incidence of iron deficiency anemia and of premenstrual tension. Seizures related to menses also are controlled. Some studies find a reduction in rheumatoid arthritis. Most of the cardiovascular complications of pills are thought to be dose related. Since today's pills contain approximately the same dose as a whole cycle of the original pills, it is expected that these risks will be greatly reduced, especially with better screening of candidates that is now the rule.

There are an estimated 8-10 million oral contraceptive (OC) users in the U.S. Investigation of the effects of OCs on neoplasia is not easy; currently 4 investigative methods are used: 1) case reports, 2) disease rate and trends, 3) case-control studies, which are the main source of careful retrospective information, and 4) cohort studies, which compare the incidence of disease in patients exposed to suspected environmental factors, and in those who are not exposed. Major risk factors for carcinoma of the breast are female sex, age, genetic predisposition, previous benign breast disease, and previous cancer of one breast; undetected breast cancer may be present for many years before diagnosis, and risk is increased in patients with chronic cystic mastitis or
fibrocystic disease
of the breast. Clinical observations have suggested a strong association between endocrine influence and the incidence or progression of breast cancer; current evidence tends to support the role of estrogens in the etiology of carcinoma of the breast with respect to long-term estrogen administration, but this evidence is not valid for young patients who are on combined OCs. Most studies have documented a decreased risk of benign breast disease with length of OC use persisting for 4 years; these studies, however, did not analyze lesions by histologic type. Studies that show a protective effect on benign disease do not show the same protective effect for breast cancer. Data from cohort studies show no association of OCs with breast cancer. Since 1972 a number of reports have associated OCs with liver tumors, stating that risk increases with duration of use. A national survey revealed that the frequency of malignant tumors increased with age, but that the frequency of benign lesions had a peak in the 26-30 age group which corresponds to increased use of OCs. Benign tumors are dangerous because they tend to rupture spontaneously. The association between pituitary adenoma, causing postpill amenorrhea, and OC use is very controversial. OC use may also cause endometrial hyperplasia; postmenopausal estrogen use has also been associated with
endometrial carcinoma
, although the causal relationship has never been proven; progestogens may be useful in the therapy of some endometrial carcinomas. Carcinoma of the cervix seems to be more influenced by age at 1st intercourse and by multiple sexual partners than by OC use; several case-control studies have shown that there is no significant difference between incidence among OC users and nonusers. Data about the association between OCs and ovarian carcinoma are reassuring but incomplete. OCs should not be used in patients with positive chorionic gonadotropin titers who have been treated for hydatidiform mole.

Oral contraceptive (OC) labeling disclosure of possible benefits from use of the products, was recommended by the U.S. Food and Drug Administration's (FDA) Fertility and Maternal Health Drugs Advisory Committee at its February 11 meeting. Committee member Howard Orr, Centers for Disease Control, noting the emphasis on cautionary and warning statements contained in current OC labeling maintained: "Women should make informed decisions and this is the other half. The package insert must include the benefits information." The recommendation by the committee represents a shift in the approach to what constitutes proper labeling for OC products. Since first approved, the drugs have never carried a discussion of benefits on their labels. "A number of additional benefits from OCs--other than contraception--have emerged from the large number of studies recorded in the literature on OC use," Ron Nelson, White Memorial Medical Center, stated. "Studies cited a more regular and lighter menstrual flow, resulting in less blood loss and lower iron deficiency and anemia in contraceptive pill users, and dysmenorrhea and premenstrual tension have been sifnificantly reduced." "Ovarian cysts and pelvic inflammatory disease occurred less frequently in pill users than in controls," Nelson continued, "and the incidence of
fibrocystic disease
of the breast were less. There are some instances where OCs may incur protection against the development of ovarian cancer,
endometrial cancer
, and rheumatoid arthritis." Orr added: "I think there are 2 good studies that show almost a total elimination of ectopic pregnancy with women who took the pill. Given that now there's an epidemic of the disease going around, I think it's worth adding." The committee was asked by FDA last November to recommend changes in the current physician and patient OC labeling. FDA's Solomon Sobel, MD, Endocrine and Metabolic Drugs Division, told the committee that an agency subcommittee would review the recommendations, present them to the committee in May for final comment, then publish them in the Federal Register.

The PTEN hamartoma tumor syndrome, manifestations of which include Cowden disease and Bannayan-Riley-Ruvalcaba syndrome, is caused by various mutations of the PTEN gene located at 10q23. Its major criteria are macrocephaly and a propensity to develop breast and thyroid cancers as well as
endometrial carcinoma
. Minor diagnostic criteria include hamartomatous intestinal polyps, lipomas,
fibrocystic disease
of the breasts, and fibromas. Mutations of PTEN can also be found in patients with Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum). The authors report the case of a 17-year-old girl who had a severe cyanotic cardiac malformation for which surgery was not advised and a heterozygous missense mutation (c.406T>C) in exon 5 of PTEN resulting in the substitution of cysteine for arginine (p.Cysl36Arg) in the protein, which was also found in her mother and sister. The patient presented in the pediatric emergency department with severe spastic paraparesis. A magnetic resonance imaging study of the spine showed vertebral hemangiomas at multiple levels, but stenosis and compression were maximal at level T5-6. An emergency T5-6 laminectomy was performed. The decompression was extremely hemorrhagic because the rapid onset of paraparesis necessitated prompt treatment, and there was no time to perform preoperative embolization. The patient's postoperative course was uneventful with gradual recovery. This represents the first report of an association of a PTEN mutation and multiple vertebral angiomas. The authors did not treat the remaining angiomas because surgical treatment was contraindicated without previous embolization, which in itself would present considerable risk in this patient with congenital cyanotic heart disease.
