It is estimated that 10-15 million women use oral contraceptives in the U.S. The 2 types of pills available are combination products containing both an estrogen and progestin, and single entity products with only progestin. Although more side effects are associated with estrogen, combination pills are the preferred prescription. Most often side effects are mild and disappear after continued use or switching to another type of pill. Some of the side effects are nausea; weight gain; chloasma; cervical extrophia and leukorrhea; hypermenorrhea; spotting and breakthrough bleeding; galactorrhea and pituitary tumors; choreiform movement disorder; endometrial cancer; and, hepatic effects. Fetal exposure to exogenous estrogens and progestins has been reported to result in increased risk for the heart and neural tube defects. Teratogenic effects subsequent to discontinuation of OCs does not appear to be a risk. The beneficial side effects of oral contraceptives are that the incidence of menorrhagia, benign breast neoplasm, dysmenorrhea, iron-deficiency anemia, premenstrual tension, acne, and ovarian cysts are lower in OC users. Thryoid diseases may be reduced by OCs.

A phase I multicenter evaluation of a novel antiestrogen, toremifene, was undertaken in postmenopausal women with various advanced difficult-to-treat malignancies. One hundred and seven women were treated at one of six dosage levels (10, 20, 40, 60, 200, or 400 mg/d orally) for at least 8 weeks. Weekly evaluations for toxicity were conducted. The most common side effects were nausea (31%), vomiting (12%), and hot flashes (29%). Five patients were removed from the study for possible adverse reactions: three patients experienced hypercalcemia; one experienced tremulousness, fatigue, and inability to think clearly; and one had vaginal bleeding. Twelve patients died while on study, 11 with disease progression and one with a pulmonary embolus. Sex hormone-binding globulin (SHBG) levels increased and there was a modest decline in serum antithrombin III levels. Four of 48 assessable patients had partial responses: three with breast cancer and one with endometrial cancer. Toremifene was generally well tolerated at the doses tested.

Twenty-two evaluable patients with advanced endometrial cancer were treated with teniposide 100 mg/m2/week administered as a 30-60-minute infusion. Escalations of 20 mg/m2/week to a maximum dose of 160 mg/m2 were performed in patients without toxicity. Seventeen of the 22 patients had prior chemotherapy. Two patients had a partial response (95% upper confidence bound for response: 25.9%). Toxicity was minimal. Four patients had white blood cell counts of less than 2,000/mm3 but only two with less than 1,000/mm3. Only one patient had a platelet count between 25,000 and 50,000, and no bleeding or septic episodes were noted. Four patients had mild nausea, and eight mild nausea and vomiting. Teniposide displays no major activity in patients with advanced endometrial cancer who have had prior chemotherapy.

Toremifene is a triphenylethylene derivative structurally and pharmacologically similar to tamoxifen. This Phase I trial assessed the safety, pharmacokinetics, anti-estrogenic, and estrogenic effects of toremifene at six dose levels (10, 20, 40, 60, 200, and 400 mg/day). The most common side-effects associated with therapy included gastrointestinal (nausea/vomiting 43%), anti-estrogenic (hot flashes 29%), and CNS (dizziness/vertigo 12%). Three patients with bone metastases from breast cancer developed hypercalcemia. At doses greater than or equal to 40 mg/day a decline in LH and FSH occurred which was not statistically significant. At all doses tested SHBG rose during therapy. A dose dependent estrogenic blockade was seen on the vaginal epithelium following challenge with transdermal estradiol. Steady-state concentrations of toremifene were reached within 4 weeks, and at doses greater than or equal to 60 mg/day ranged from 879-3445 ng/ml. The half-life was found to be 5 days, and at three weeks following discontinuation of treatment concentrations greater than 24 ng/ml were detected. The N-desmethyl and 4-hydroxy metabolites achieved steady state levels within 4 weeks and had half-lives of 6 and 5 days respectively. Partial responses were seen in 4 patients, 3 with breast cancer treated at 200 mg/day and 1 with endometrial cancer treated at 400 mg/day.

Autologous lymphokine-activated killer (LAK) cells and recombinant human interleukin-2 (rIL-2) were administered intraperitoneally (IP) to 24 patients with malignancies limited to the peritoneal space. Ten patients had ovarian cancer, 12 had colorectal cancer, and one patient each had endometrial carcinoma and primary small-bowel adenocarcinoma. All ovarian cancer patients, three of twelve colorectal cancer patients, and one patient with endometrial carcinoma had received prior therapy. Patients received IL-2 100,000 U/kg every 8 hours intravenously (IV) for 3 days, and 2 days later underwent daily leukapheresis for 5 days. LAK cells were generated in vitro by incubating the peripheral blood mononuclear cells in IL-2 for 7 days and were then administered IP daily for 5 days through a Tenckhoff catheter (Davol, Inc, Cranston, RI) together with IL-2 25,000 U/kg IP every 8 hours. All but one patient completed at least one cycle of therapy. Toxic side effects included minor to moderate hypotension, fever, chills, rash, nausea, vomiting, abdominal pain and distension, diarrhea, oliguria, fluid retention, thrombocytopenia, and minor elevations of liver function tests; all of these rapidly improved after discontinuation of IL-2. One patient had a grand mal seizure, and one suffered a colonic perforation; these were felt to be treatment-related. IP fibrosis developed in 14 patients and limited repeated cyclic administration of this therapy in five patients. Two of 10 (20%) ovarian cancer patients and five of 12 (42%) colorectal cancer patients had laparoscopy- or laparotomy-documented partial responses. We conclude that LAK cells and rIL-2 can be administered IP to cancer patients, resulting in moderate to severe short-term toxicity and modest therapeutic efficacy. Further investigation of this form of adoptive immunotherapy modified to address the problem of IP fibrosis and with lower IP IL-2 doses is justified by these initial results.

Four patients with recurrent or advanced endometrial cancer have undergone combination chemotherapy with Cyclophosphamide, Adriamycin and Cisplatin (CAP). All drugs were administered by I.V. on day 1 in the following doses: Cyclophosphamide 500 mg/m2, Adriamycin 50 mg/m2 and Cisplatin 50 mg/m2. The treatment was repeated every 4 weeks and continued as long as there was disease progression. Two complete clinical responses and two partial responses were achieved. Based on these good results, we have initiated post-operative prophylactic chemotherapy using CAP in high risk patients. Adverse effects including myelo-suppression, nausea, and vomiting, and alopecia were seen in almost all patients. In no case, however, did any patient experience life-threatening toxicity. Based on our experience, CAP therapy appears tolerable when used per our schedule.

Mechanism of action, indications, side effects and contraindications of oral contraceptive agents (OCA) are reviewed. OCA can be divided into two groups: consecutive and combined agents. Combined OCA contain both estrogens and gestagens and are taken for 3 weeks, while consecutive OCA contain only estrogens and are taken for 2 weeks followed by 1 week of combined OCA until the onset of menstruation. Biological activity of synthetic gestagens is estimated by a dosage which results in a delay of menstruation by 2 weeks. Gestagens norethindrone and norethynodrel were shown to be equally effective, while ethinodiol diacetate and norgestrel were 15-30 times more effective. Estrogen component of OCA is represented by ethinyl estradiol or mestranol. Combined OCA are more effective than consecutive OCA; probability of undesirable pregnancy during administration of combined OCA does not exceed 0.2%. The most frequent side-effects of OCA include nausea, headache, uterine hemorrhage, and changes in libido. OCA can affect the endocrine and reproductive systems. Major endocrine effects of OCA include changes in the cortisol metabolism in the adrenal glands, increase in the level of thyroid-binding globulin in the thyroid gland, changes in the glucose metabolism in the pancreas, inhibition of the luteinizing hormone releasing hormone in the hypothalamus with simultaneous decrease in the production of pituitary gonadotropins and inhibition of the ovulation. The most serious side-effects of OCA include cholelithiasis, thrombophlebitis, thromboembolism, liver adenoma, and myocardial infarction. Absolute contraindications to the use of OCA include hypertension, hyperlipidemia, breast or endometrial cancer, pregnancy, cardio-vascular diseases, liver diseases, and kidney insufficiency.

To evaluate the role of hexamethylmelamine (HMM) in the treatment of endometrial cancer, 20 women with metastatic or recurrent endometrial carcinoma received HMM orally at a dose of 8 mg/kg/day. Six patients (30%) showed a partial response, with a median duration of response of 3.5 months and a range of 1 to 7 months. Two patients responded to HMM as a second-line agent following previous treatment with nonhormonal chemotherapy. There were no complete responses. The major toxicities noted with HMM therapy were nausea, vomiting, and neurotoxicity. In 6 patients (30%), therapy with HMM was discontinued because of toxicity. Although HMM is active against endometrial cancer when given at a dose of 8 mg/kg/day, it appears to have limited usefulness because toxicity precludes its prolonged administration.

Methyl-GAG was given to 71 patients with advanced malignancies as a weekly brief infusion (30-120 minutes) or as a biweekly 24- or 120-hour infusion. Mucositis (stomatitis, pharyngitis, esophagitis, and, rarely, inflammation of other mucous membranes) was dose-limiting in all three schedules. Generalized fatigue, malaise, myalgia, dysesthesias, nausea, and vomiting were more frequent in the brief-infusion schedule. Myelosuppression was mild and not dose-related. Fever, ventricular arrhythmias, skin rash, tender swelling of the palms, neuropathy, and paralytic ileus were rare. Toxicity was increased in patients with renal insufficiency or "third-space" fluid but was not increased by hepatic dysfunction. Cumulative and overlapping toxicity was evident only in the weekly schedule. Higher doses of methyl-GAG were tolerated when the duration of infusion was increased. The recommended doses for phase II trials are 700 mg/m2 weekly as a 1-2 hour infusion, 850 mg/m2/24 hours biweekly, and 1500 mg/m2/120 hours biweekly. Therapeutic effects were seen in all schedules and included objective responses in colon carcinoma (one of 13 patients), renal cell carcinoma (one of nine), and Hodgkin's lymphoma (one of two) and objective improvements in esophageal carcinoma (one of three), endometrial carcinoma (two of two), and leiomyosarcoma (one of three).

This paper reviews both minor and major adverse reactions caused by estrogenic substances (natural and synthetic, steroidal and nonsteroidal) of which diethylstilbestrol is the prototype of nonsteroidal synthetic estrogen. Minor side effects include nausea, breast tenderness, and excessive cervical secretions (most common), headache, and water and salt retention (less common and often eradicated by lowering estrogen dosage). Vertigo, yeast infections, depression, and photosensitivity are other minor effects. Major side effects are discussed in some detail. Major effects include those on the endocrine system (e.g., feminization in boys and men and precocious puberty in girls); breast tumors; endometrial carcinoma; ovarian tumors; hypertension; thromboembolism; blood clotting excesses; various metabolic effects (including lipid metabolism and carbohydrate metabolism alterations); liver changes (bile alterations and neoplasms); porphyria; melanoma; and effects on a fetus in situ during maternal estrogen administration. In general, lowering doses of estrogen should help eradicate or alleviate most of these effects.
