Long-acting oral contraceptives (OCs) for women were available for clinical experimentation in 1969. Through the country, 29 provinces, cities, and autonomous regions participated in this expirement. Based upon the cases between 1969 and 1976 findings from this expirement can be summarized as follows: 1) the 3 types of long-acting OCs have proved to be very effective, and the rate of breast cancer and cervical cancer is lower than the normal rate. The childbearing ability can be restored rapidly after discontinued use of the contraceptives. The impact on menses and metaboliism is not very serious. The health of the users and the newborn babies has not been found to be endangered. Statistics show that long-acting OCs are comparatively more secure measures for birth control; 2) some users have experienced dizziness, nausea, and excessive leukorrhea, and discontdiscontinued because of discomfort and inconvenience. This situation has some impact on the popular use of long-acting OCs. Research and studies are underway on a reduced dosage and reduction of side effects; 3) women who suffer from hepatitis, nephritis, a history of liver and kidney problems, breast tumors, cervical cancer, diabetes, active low blood sugar, or a history of having over-sized babies, or an overweight problem should not use OCs. Women who suffer from high blood pressure can only use OCs with a doctor's advice and caution.

To assess the feasibility and effectiveness of combined therapy on locally advanced cervical cancer, we entered 38 patients into a study. The patients were treated with mitomycin-C (10 mg/m2) on Days 1 and 30 and 5-FU (1000 mg/m2) on Days 1 to 4 and Days 30 to 33. In 5 weeks 4500-5000 cGy was given concurrently, followed by radioactive implants. Twenty-six patients had an early-stage disease (IB-IIB) and twelve had a late-stage disease (IIIB-IVA). Eighty-seven percent (33/38) of the patients had a tumor measuring 5 cm or more. The other 5 patients with a tumor size under 5 cm had biopsy-proven positive pelvic nodes; 2 of these 5 patients had a pretherapy hysterectomy. Tumor response, complete (CR) vs partial (PR), was assessed in 36 patients 3 months after completion of therapy. A CR was noted in 80% (29/36) of the patients. The PR status conferred a detrimental effect on the pelvic disease control (PDC), disease-free survival (DFS), and survival (S) while late stage correlated with the development of distant metastases (DM) and a poor DFS. PDC was obtained in 93% (27/29) of the patients who had a CR, as compared to only 43% (3/7) of those with a PR (P = 0.0228). The DFS and S rates were 59 and 77% for patients with a CR and 21 and 19% for those with a PR; respective P values were 0.0340 and 0.0002. Eleven percent (3/26) of the patients with an early stage developed DM, as compared to 50% (6/12) of those with late stage, (P = 0.0016). The DFS rates were 80 and 37% for patients with an early and late stage, respectively (P = 0.0141). Four patients developed transient neutropenia and one had transient thrombocytopenia. The second dose of mitomycin-C was omitted in 4 patients due to persistent neutropenia in 3 and to transfusion-related hepatitis in 1. Two percent (5/21) of the patients who had a staging laparotomy developed wound dehiscence. Three patients developed non-cancer-related small bowel obstruction requiring surgery. We concluded that this combined regimen was well tolerated. Although it was effective in controlling the cancer in the pelvis, this regimen failed to control DM in late-stage patients.

With an attempt to diminish the post-transfusion hepatitis following radical hysterectomy, the study was made on 27 cases of cervical cancer undergone the operation. Fifty cases with blood transfusion immediately prior to the study was taken as control group. Under general anesthesia, 800 ml of venous blood was drawn from the peripheral vein under simultaneous infusion of 1,000 ml of Saviosol to maintain the circulating blood volume. The blood was returned after hemostatizing procedures. Of the study group, the blood loss, operation time, urinary output during the operation, and drainage amount were 960 g, 157 minutes, 350 ml and 160 ml respectively, while those of control group were 930 g, 164 minutes, 150 ml and 280 ml. The circulation status remained within normal limits, no bleeding tendency was appeared. Blood loss of the study group was estimated 960 g, however the actual blood loss calculated was on l6 719 g. There were no particular complication in the study group, while there was 12% of hepatitis among the control group. The advantages were concluded as 1) Patient was under normovolemic state when the operation started. 2) The blood transfused had normal O2 transport and hemostatic capacity. 3) The management of the patient was not so difficult and no special equipment and technique were needed.

We report herein a case (46 years, female) of very early idiopathic portal hypertension. During an examination for in situ uterine cervical cancer, splenomegaly and hypersplenism were incidentally found. CT and MRI showed a nonatrophic liver with dilated portal veins and marked splenomegaly. The portal venous blood flow was increased, while portal venous blood pressure was not high. The spleen (1,220 g) showed hyperplasia of white pulp and congestion. The lobular architecture of the liver was well-preserved, and the subcapsular regions were not atrophic or dropped out. The portal tracts were not fibrotic, and portal veins were neither stenotic nor sclerotic. Instead, lymphoid cell infiltrations were found in about half the portal tracts, and there was subendothelial mononuclear cell infiltration of small portal vein branches. The hepatic lobules showed non-specific reactive change. This case suggests that early hepatic changes recognizable histologically in this disease are lymphoid cell infiltration of the portal tract and of subendothelial regions of portal vein branches, and nonspecific lobular hepatitis. These hepatic changes, as well as marked splenomegaly, may represent an altered immunophenomenon of this disease.

Ten million new cancer patients are diagnosed each year worldwide. Many specific causes of cancer are known, ranging from factors related to lifestyle, diet and chronic infections to occupational exposures. Primary and secondary prevention continue to be of major importance in cancer control globally. The global burden of cancer, especially the part attributable to infectious diseases, disproportionally affects populations in developing countries. Inadequate access to treatment (pharmaceuticals and other modern technology) plays a role in perpetuating this disparity. Drugs and vaccines may not be accessible because of excessive cost or because development of the required products has been neglected. The remarkable advances in molecular understanding of the carcinogenesis process over the past 25 years have transformed the approaches to cancer control. Promising new tools in preventive oncology, such as immunization (vaccines) and chemoprevention, have emerged. Vaccines are currently being tested in trials e.g., against hepatitis B virus and human papillomaviruses. Chemoprevention has been successfully achieved in animal experiments, and has been validated in several clinical trials. The current agents and strategies should not be regarded as a panacea; more effective and safer vaccines and chemopreventive agents are needed. Future enhanced efforts on an international basis are needed to coordinate the prevention and intervention research efforts in a cost-efficient and affordable manner. Cancer prevention deserves continuing high priority in terms of both research and application, also in the developing countries. New ventures may be built on possible expansion of IARC's role in prevention and intervention research into a "Global Science Force" by following the examples of e.g., the Gambia Hepatitis Intervention Study and the cervix cancer screening trials in India. WHO's support with its regional offices would be beneficial, together with further national funding and support, and research collaboration and funding from more wealthy countries.

Drug-induced hepatotoxicity accounts for more than a third of the cases of acute liver failure in the United States. In complex medical conditions, the diagnosis of drug-induced liver injury may be confounding and, specifically, the potential hepatotoxicity of chemotherapeutic agents may be easily overlooked. Two fatal cases of cholestatic hepatotoxicity have been previously reported, clearly implicating gemcitabine therapy. We report a third fatal case of cholestatic liver failure that we think is strongly linked to the use of gemcitabine. This chemotherapeutic agent is a fluorine analog with broad-spectrum antitumor activity commonly used in the treatment of breast, lung, prostate, and cervical cancer. The case we report is of a 45-year-old woman with a history of metastatic breast cancer to her spine. The patient was in remission for two years before she presented with a compensated mixed hepatitis of mild to moderate severity. Inpatient work-up found metastases to the right humerus and inferior pubic ramus, but none in the liver. Gemcitabine and carboplatin therapy was initiated for relapse of breast cancer. The patient's liver enzyme elevation diminished, but did not normalize before the start of chemotherapy. She received four courses of gemcitabine/carboplatin and subsequently presented with decompensated, severe cholestatic hepatitis. Transjugular liver biopsy displayed marked cholestasis and hepatocellular injury consistent with drug-induced hepatoxicity. Gemcitabine has been extensively studied in the oncology literature and at this time is thought to be a low-risk hepatotoxin causing hepatic adaptation and transient, reversible liver enzyme elevation, rarely leading to termination of gemcitabine therapy for solid tumors. We believe that gemcitabine therapy, particularly in the setting of preexisting liver injury or metastases to the liver, increases the relative risk of severe and potentially fatal hepatic injury possibly by idiosyncratic and dose-dependent mechanisms. We recommend careful monitoring and dose adjustment of gemcitabine in patients with abnormal liver function tests or evidence of hepatic metastases until further study clarifies this issue.

WF 10 [TCDO, Oxoferin, Immunokine, Macrokine] is a 1:10 dilution of tetrachlorodecaoxide formulated for IV delivery. It was developed by Oxo Chemie in Switzerland as an adjunctive therapy to combination antiretroviral and opportunistic infection prophylaxis regimens in AIDS patients. WF 10 specifically targets macrophages. Oxo Chemie has worldwide patent rights to WF 10 and Dimethaid Research has an exclusive licence for marketing and distribution in Canada. In May 2002, Oxo Chemie was acquired by Dimethaid Research. Oxo completed a trial in 72 cervical cancer patients undergoing radiation therapy in 1989. Results from this trial demonstrated complete remission in 75% of patients receiving WF 10. A follow-up placebo controlled trial in 1996 produced similar results. WF 10 has received regulatory approval in Thailand for postradiation cystitis following a trial completed in 1998 in 20 patients following radiation treatment for cervical carcinoma. This authorisation also allows limited availability of WF 10 at the physician's request in Germany. WF 10 is also available under Health Canada's Special Access Program. Oxo Chemie has completed a controlled randomised, crossover study in France in 1991 that examined the effects of 103 patients with acute radiation dermatitis and radiation- or chemotherapy-induced mucositis. Results demonstrated that WF 10 significantly improved lesions and accelerated recovery without side effects. Topical tetrachlorodecaoxide in a less concentrated formulation (1:55) is marketed in many countries as Oxoferin for wound healing. WF 10 is approved for use in Thailand under the name IMMUNOKINE in patients with postradiation chronic inflammatory disease including cystitis, proctitis and mucositis. In July 2003, the European examiners informed Oxo Chemie that they intend to grant the company additional patents to the technology platform that supports WF 10, extending the European protection granted in 1992 to cover a much broader range of diseases. The patents will be granted in Austria, Belgium, Cyprus, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Liechtenstein, Luxembourg, Monaco, the Netherlands, Portugal, Spain, Sweden, Switzerland and the UK. Patent claims cover potential treatment for autoimmune disease, organ transplant or graft rejection, lymphoma and inflammation manifested as hepatitis or chronic obstructive pulmonary disease.

Accumulating data indicate that tumor-infiltrating regulatory T cells (Treg) are present in human tumors and locally suppress antitumor immune cells. In this study, we found an increased Treg/CD8 ratio in human breast and cervical cancers. A similar intratumoral lymphocyte pattern was observed in a mouse model for cervical cancer (TC-1 cells). In this model, systemic Treg depletion was inefficient in controlling tumor growth. Furthermore, systemic CTL-associated antigen-4 (CTLA-4) blockade, an approach that can induce tumor immunity in other tumor models, did not result in TC-1 tumor regression but led to spontaneous development of autoimmune hepatitis. We hypothesized that continuous expression of an anti-CTLA-4 antibody localized to the tumor site could overcome Treg-mediated immunosuppression and locally activate tumor-reactive CD8+ cells, without induction of autoimmunity. To test this hypothesis, we created TC-1 cells that secrete a functional anti-CTLA-4 antibody (TC-1/alphaCTLA-4-gamma1 cells). When injected into immunocompetent mice, the growth of TC-1/alphaCTLA-4-gamma1 tumors was delayed compared with control TC-1 cells and accompanied by a reversion of the intratumoral Treg/CD8 ratio due to an increase in tumor-infiltrating IFNgamma-producing CD8+ cells. When local anti-CTLA-4 antibody production was combined with Treg inhibition, permanent TC-1 tumor regression and immunity was induced. Importantly, no signs of autoimmunity were detected in mice that received local CTLA-4 blockade alone or in combination with Treg depletion.

For several hundred years, Patrinia heterophylla has been used in traditional Chinese medicine as a treatment for abscesses, hepatitis, tonsillitis, ulcers, etc. Recent research suggests that it may also have some anti-cancer activity. We have extracted five pure compounds from this plant; two known flavonols without bio-activity, one known isocoumarin glucoside that exhibits some cytotoxic activity toward HeLa cervical cancer cells, and two novel compounds that show considerable cytotoxic activity toward HeLa cells.

Sexually transmitted diseases (STDs) in women are of great concern to all health-care providers since many of them are preventable and/or treatable conditions which, if left untreated, could have serious sequelae such as pelvic inflammatory disease, infertility, cervical cancer, systemic disease, etc. They may also become a major public health problem when dealing with diseases such as hepatitis, etc., or in people with human immunodeficiency virus. We present here a comprehensive review of the common causes of STDs and their treatment.
