Vulvar carcinoma is a rare cancer. It is more frequent among older women, but the incidence is increasing among younger women. The incidence of VIN may be rising in younger women as well. Different factors have been associated with an increased risk for vulvar cancer (HPV, age, smoking, education, diet, genital infections, infrequent pelvic examinations, socioeconomic status, immunosuppressive diseases); however, conclusive epidemiologic evidence is lacking. More studies with larger sample sizes are needed to understand more fully the role of these and other as yet unknown factors in the etiology of vulvar cancer. At present, studies of the molecular risk assessment for VIN and vulvar cancer focus mostly on HPV. The treatments for VIN are painful, and the disease has a high risk of recurrence. The treatments for vulvar cancers are morbid, even though radical vulvectomy is being replaced by the less morbid wide local excision and unilateral groin lymph node dissection. Therefore, VIN and vulvar cancer benefit from early detection, and their morbidity is decreased by early treatment. Screening should be performed by the primary care practitioner and should focus on women with HPV; women who smoke; and women who have other preinvasive disease of the cervix, vagina, or perianal area. Chemoprevention and an HPV vaccine may eventually be promising, but no studies have yet been performed. Patients should be educated about performing vulvar self-examination stopping smoking, being persistent about insisting on a biopsy if symptoms persist, and avoiding exposure to HPV.

Endometrial cancer is the most frequently seen gynecologic neoplasm, but it fortunately has low mortality, which is due largely to its presentation with abnormal bleeding and its subsequent early diagnosis. The morbidity associated with therapy for early lesions is moderate. Hyperplasia with atypia should be treated as early cancers. Many molecular markers are currently under study. Markers may soon help us identify invasive lesions at higher risk of recurring and thus more suitable for adjunct therapy. Screening in the general population is not recommended, but a high-risk group that is more suitable for screening could be identified, including obese and nulliparous women, those treated with unopposed estrogen or tamoxifen, or those with family or past histories of breast or colon cancer. Development of chemoprevention with an oral contraceptive during the reproductive years is under way, and there may be a role for chemoprevention in the reversal of hyperplasias.

Vaginal cancer is infrequent, but the morbidity associated with treatment is high. Delays in diagnosis account for presentations in advanced stages. Screening is probably not warranted given the low incidence, but inspection of the vagina should be performed at the time of Pap smear screening. No molecular markers are currently promising. Chemoprevention with retinoids may be feasible.

Ovarian cancer accounts for only 4% of cancers in women, but it is the leading cause of death from gynecologic malignancies in the United States. In the general population, a woman's lifetime risk of ovarian cancer is 1.4% but this risk can increase substantially in women with a strong family history of the disease. The high mortality rate from ovarian cancer is due primarily to the difficulty in detecting the disease in early stages; the disease tends to be asymptomatic until it is well advanced. The primary care physician needs to be alert to the possibility of an ovarian malignancy in all women with an intact ovary or ovaries who present with abdominal or pelvic complaints. There are no current recommendations for routine screening for ovarian cancer in the general population. Even in high-risk women, there are currently no convincing data to support extensive screening, although a number of studies looking at this issue are under way. Despite this lack of conclusive evidence, a consensus panel on ovarian cancer convened by the NIH recently issued guidelines for screening high-risk women. They recommend annual rectovaginal pelvic examination, testing of CA 125 level, and transvaginal ultrasonography. Color flow Doppler analysis of the ovarian vessels is also being studied as a possible screening modality. BRCA1 gene testing may soon play a role in women with a strong family history of the disease. Given its high mortality rate, primary prevention strategies for ovarian cancer should be used whenever possible. Oral contraceptive use appears to reduce the risk of ovarian cancer. Prophylactic oophorectomy may be suggested for women at particularly high risk of the disease. Here, too, the primary care physician can play an important role in helping a patient understand the risks and benefits of these options.

BACKGROUND:Although the technique for gracilis myocutaneous vaginal reconstruction was first described in the mid-1970s and has been used in conjunction with pelvic exenteration since that time, there is little available information regarding sexual adjustment after such a procedure. The purpose of this study was to assess the sexual adjustment of women who underwent pelvic exenteration and gracilis myocutaneous vaginal reconstruction at the study institution. METHODS:In a prospective study design, 95 patients were identified who underwent pelvic exenteration and gracilis myocutaneous vaginal reconstruction at the study institution from 1977 through 1989 and a convenience sample was selected of 44 patients who completed a modified version of the Sexual Adjustment Questionnaire (SAQ) when they returned to the gynecologic oncology outpatient clinic for routine follow-up care. A vaginal assessment was also performed by the attending physician. RESULTS:Twenty-one of 40 patients (52.5%) completing the questionnaire reported not resuming sexual activity after surgery; 19 patients reported sexual activity between 1.5 months to 12 years postoperatively. Of the patients who resumed sexual activity, 84% did so within 1 year of surgery. The most common problems noted by patients in adjusting to sexual activity after surgery were self-consciousness about the urostomy or colostomy and being seen in the nude by their partner, vaginal dryness, and vaginal discharge. The mean rank of preexenteration SAQ scores was 66.4, and the mean rank of postexenteration scores was 48.7 (P < 0.0001), demonstrating that sexual adjustment after exenteration was significantly poorer than before the surgery. On the basis of data gathered from a vaginal assessment form, 31 of 44 patients (70.4%) were judged to have a potentially functional neovagina. CONCLUSIONS:Based on the findings of this questionnaire study, sexual adjustment is often significantly impaired in women after pelvic exenteration and gracilis myocutaneous vaginal reconstruction. Future modifications in surgical technique, more realistic patient counseling and aggressive postoperative support will hopefully minimize such problems.

Cervical cancer remains an important health problem for women worldwide, despite its decline in countries where organized screening programs are in place. The morbidity of treatment and the mortality for advanced lesions are high, a frustrating situation because the cervix is accessible and a good screening test, the Pap smear, exists. HPV is an important risk factor, and the molecular evidence for its role is overwhelming. Molecular markers may soon help us decide which lesions are at highest risk of progression to invasion and which invasive lesions are likely to recur. Chemoprevention of precursor lesions is promising. An HPV vaccine could be effective in eradicating this cancer.

Sarcomas are rare tumors with unpredictable prognosis. They are treated similarly to endometrial cancers. Little is known of epidemiologic risk factors for sarcoma; similarly, little work has been performed assessing molecular alterations in sarcomas. Because of their rarity, uterine sarcomas are not suitable for screening. Chemoprevention studies might target those at risk for recurrence or a second neoplasm.

GTD occurs in fewer than 1 in 1200 pregnancies in the United States, but it is much more common in Asia and Latin America, where its incidence may be as high as 1 in 200 pregnancies. Risk factors for GTD include advanced or young maternal age, low socioeconomic status, and prior hydatidiform mole. Early diagnosis and prompt treatment are key to a favorable outcome, and thus recognition of the signs and symptoms of the disease is important for all physicians. Because these diseases have low incidences and occur after reproductive events, screening for them in the general population is not worthwhile. No chemopreventive agents have yet been studied in women at risk for GTD, but the oral contraceptive is a good candidate.
