Cervical carcinoma in pregnancy

Invasive cervical cancer in pregnancy

Cervical cancer is the commonest malignancy which complicates pregnancy, but the management remains controversial. We reviewed our patients in an attempt to identify the best management options which resulted in long-term survival for the mother and a live baby. The total number of pregnancies managed between January, 1981 and March, 1995 was obtained from the hospital records, and patients with invasive cervical cancer diagnosed during pregnancy or within 12 months of delivery were identified. The case records were reviewed. Between January, 1981 and March, 1995 there were 22 cases of cervical cancer diagnosed either during pregnancy or within 12 months postpartum. This gave an incidence of cervical cancer associated with pregnancy of 1 in 3,817 pregnancies or 0.26 per 1,000 pregnancies. Eleven patients had microinvasive disease. Nine were treated by cone biopsy and 2 by radical hysterectomy. Nine patients had Stage 1B and 1 had Stage 2A disease and all were treated with radical hysterectomy. One patient had Stage 3B disease and was treated with radiotherapy and chemotherapy followed by simple hysterectomy. Fourteen patients delivered vaginally. Twenty of the 22 patients were delivered of live babies which survived. The patients have been followed from 1 month to 13 years with only 1 recurrence, and all 22 remain alive. We conclude that all pregnant women should have a Pap smear performed antenatally. Cone biopsy can be safely performed in pregnancy and may be adequate treatment for microinvasive squamous cell carcinomas. Treatment, including the timing of delivery, must be individualized, with the patient playing an important decision-making role.

Cervical carcinoma associated with pregnancy

Because of the uncommon synchronous occurrence of pregnancy and invasive cervical carcinoma, this disease entity remains poorly understood. In addition inconsistent reporting has precluded meaningful meta-analysis. About 1 in 2000 pregnancies are associated with cervical cancer and pregnancy is a complication in approximately 3 percent of patients with cervical cancer. There is little evidence to suggest that the pregnancy has an influence on prognosis. Although not firmly established, vaginal delivery may have an adverse effect on outcome. Timing of delivery must be individualized inasmuch as there is a role for delaying treatment in order to achieve fetal lung maturity. Surgery and radiotherapy should be utilized in the same stage-dependent manner as in nonpregnant patients but management should be individualized and undertaken by a multidisciplinary team. These and other issues are discussed more fully in this review.

Management problems associated with carcinoma of the cervix diagnosed in the second trimester of pregnancy

A 29-year-old women presented in the second trimester of pregnancy with a stage IIB squamous carcinoma of the cervix. Fundal hysterotomy was performed with a view to radical radiotherapy the following week. The patient developed a pyometra in the postoperative period due to the position and nature of the tumor. Management strategies for dealing with similar cases are outlined.

Clear cell adenocarcinoma (CCA) of the vagina and cervix in association with pregnancy

The effect of pregnancy on patients with CCA of the vagina and cervix was evaluated based upon a review of 503 cases. Eighty-five had been pregnant (24 at diagnosis), 408 had never been pregnant, and the pregnancy history was unavailable in 10 cases. All of the 24 patients pregnant at diagnosis were over 16 years of age; 14 were in the first trimester, 6 in the second, and 4 in the third trimester. By FIGO criteria, 15 were stage I, 7 stage II, and 2 were stage III. The 24 pregnant and 408 never pregnant (age corrected) cases were compared with regard to maternal hormone history, symptoms, stage, location, predominant histologic or cell type, greatest tumor diameter, surface area, depth of invasion, grade, and number of mitoses. No significant differences were detected. Twelve of the 24 pregnant patients had radical hysterectomy with or without irradiation (9 stage I, 3 stage II); of the 7 treated by local therapy (5 stage I, 2 stage II), 3 required additional therapy due to persistent disease; 4 had radiotherapy alone (1 stage I, 2 stage II, and 1 stage III); one had teletherapy followed by exenteration (stage III). Six of the 24 died 2 to 12 years after diagnosis (1 stage I, 3 stage II, 2 stage III). Eighteen are alive at 1 to 17 years. The overall 5 and 10 year actuarial survival rates (age adjusted) for the group pregnant at diagnosis (86 and 68%) do not differ significantly from the never pregnant group. Pregnancy does not seem to adversely affect the outcome of CCA. Guidelines are presented to treat pregnant patients with CCA.

Invasive cervical cancer in young women

Between 1970 and 1979, 103 women below 35 years of age with invasive cervical cancer were treated at the First Obstetrics and Gynaecology Clinic of the University of Milan. Nine patients were pregnant or less than 3 months postpartum. Estimated 10-year disease-free survival, determined by the life-table method, was 100% in stage IA (37 patients), 79% in stage IB (45 patients), 67% in stage II (15 patients), 0% in stages III (5 patients) and IV (1 patient). Prognosis was also strongly associated with lymph-node involvement, 10-year actuarial survival decreasing from 93% in lymph-node-negative to 44% in lymph-node-positive patients (P less than 0.001). The prognostic relevance of the clinical stage decreased after adjustment for lymph-node involvement, but the statistical significance of lymph-node involvement was unaffected when stage was allowed for. In the present series, the estimated 10-year disease-free survival was 80% in patients treated by radical hysterectomy compared with 62% in the group treated by total hysterectomy (stage IB to IV patients only); this difference, however, was not statistically significant when the data were adjusted for clinical stage (P = 0.10). None of the 20 patients with recurrent disease could be managed successfully.
