Nerve-sparing radical hysterectomy for stage IA2-IIB cervical cancer: 5-year survival of 501 consecutive cases.

OBJECTIVE: The purpose of this study was to assess the 5-year survival and morbidity in cases with radical hysterectomy and pelvic lymphadenectomy with pre- and postoperative irradiation performed to treat Stage IA2-IIB cervical cancer. METHODS: During a 10(1/2)-year period between July 1990 and December 2000, 501 consecutive radical hysterectomies with bilateral pelvic lymphadenectomy were performed by the same gynecological surgeon in Stage IA2, IB, IIA and IIB cervical cancer. The patients were treated by pre- and postoperative irradiation as well. RESULTS: Apart from recurrence, perioperative complications were minimal with no long-term morbidity. The absolute 5-year survival rates for the patients in Stage IA2, IB1, IB2, IIA and IIB were 94.4%, 90.7%, 84.1%, 71.1%, and 55.4%, respectively. The respective 5-year survival rates for patients without or with lymph node metastasis were 94.5% and 33.3% in Stage IB2, 81.7% and 48.7% in Stage IIA and 70.2% and 36.5% in Stage IIB, respectively. CONCLUSIONS: Nerve-sparing radical hysterectomy with pelvic lymph node dissection and pre- and postoperative irradiation remains the treatment of choice for most patients with early-stage and even Stage IIB cervical cancer. The radicalism and extent of lymph node dissection and parametrial resection should be individualized and tailored to tumor- and patient-related risk factors.

Outcome of pregnancies after cold-knife conization of the uterine cervix during pregnancy.

OBJECTIVE: To determine the incidence of cervical intraepithelial neoplasia (CIN) in pregnancy and to determine the outcome of pregnancies in women treated by cold knife conization during pregnancy. METHODS: The authors retrospectively studied the cases of 19,807 pregnant patients, who presented to the 1st Department of Obstetrics and Gynecology Semmelweis University Faculty of Medicine between January 1, 1993 and December 31, 1997. Of these, there were 1,513 spontaneous abortions, 6,170 artificial abortions and 12,124 deliveries. Cytological evidence of a high-grade squamous intraepithelial lesion (LGSIL) was found in 48 pregnant patients. A low-grade squamous intraepithelial lesion (LGSIL) was found in 55 pregnant patients. All pregnant patients with HGSIL including those with satisfactory and nonsatisfactory colposcopical examinations underwent diagnostic cold knife conization during pregnancy in the second trimester. A gynecologic pathologist (Dr. Zs. Csapó) reviewed the histopathological sections. RESULTS: Overall, 44 patients had CIN, three patients had microinvasive carcinoma (FIGO stage I/A1), and one patient had neither CIN nor invasive carcinoma in the HGSIL group. Among the 48 pregnant patients with HGSIL, there were two spontaneous abortions occurring during the 21st and the 22nd gestational weeks respectively, so the pregnancy loss rate was 4.2%. Forty patients (83%) delivered at term and six patients (12.5%) at preterm. Twenty-four patients (52%) delivered vaginally and 22 (48%) by cesarean section. Comparing this data with the control group consisting of pregnant patients who had LGSIL, the difference between the two group as regards the total number of adverse pregnancy outcome cases was not significant. In the three patients with microinvasive cervical carcinoma (FIGO stage I/A1), elctive cesarean section was performed, followed by an immediate abdominal hysterectomy at term. CONCLUSION: The incidence of CIN in pregnancy was 0.22%. The incidence of microinvasive cervical carcinoma was 0.015%. Pregnant patients with CIN who underwent cold knife conization during pregnancy were not at increased risk of adverse pregnancy outcome, however they were at increased risk of cesarean delivery.

Detection of high-risk HPV (16, 18, 33) in situ cancer of the cervix by PCR technique.

OBJECTIVE: The purpose of this study was to collect data about the incidence of high-risk HPV (16, 18, 33) types in in situ cervical cancers, and to evaluate the reliability of the morphological signs of HPV infection by comparing the presence of these signs to the PCR-proven HPV virus infection. METHODS: Fifty patients who underwent conisation at the Department of Obstetrics and Gynecology of Semmelweis University, Budapest, Hungary because of in situ cervical cancer were examined retrospectively for the presence of HPV infection by the PCR technique. The direct and indirect morphological signs of HPV infection identified in the histological and cytological samples were compared to the actual results of virus DNA amplification by PCR in the identical histological sections. The evaluation of the cytological smears and the histological sections was accomplished independently by two different pathologists. RESULTS: E6 open reading frame of HPV 16, 18 or 33 was detected by PCR in 56% (28 cases) of the histological sections of the 50 examined patients with in situ cancer. In 92% (26 patients) of the 28 HPV positive patients one HPV type was detected, while in one of the remaining two cases two HPV types (16/33), or all three types could be detected. The direct morphological signs for HPV infection proved to be 75% sensitive and 50% specific when compared to the results of PCR. Their predictive value for HPV infection was 65%. For the indirect HPV signs the sensitivity was 64% and specificity 31%. The predictive value, prognosticating the presence of HPV 16, 18, 33 infection was 54% in the same sections. Using significance analysis no significant relationship (p = 0.7728) could be detected between the positivity of indirect signs and the presence of HPV 16, 18, 33 infection, while in case of direct signs the relationship was almost significant (p = 0.0675). The joint testing of the direct and indirect signs did not improve the results (p = 0.1338). During the review of the cytological smears the specificity of the cytology in predicting true HPV infections was found to be 68% and sensitivity was 20%. The predictive value was only 50%. A significance analysis was not accomplished by this diagnostic method because of the missing data (see text). CONCLUSION: The method of Nawa et al. seems to be a reliable approach for the detection of HPV DNA in paraffin-embedded material. The three main types of HPV (16, 18, 33) are probably represented in lower percentages in CIN III in Hungary, but a larger survey is needed to obtain reliable data. The direct and indirect morphological signs of HPV infection failed to show a significant relationship with the PCR proven presence of HPV 16, 18, 33.

A retrospective study of 27 ovarian tumors of low malignant potential.

INTRODUCTION: This study was undertaken to retrospectively review the fertility-sparing surgical treatment and long-term outcome of 27 patients with ovarian tumors of low malignant potential treated at the 1st Department of Obstetrics and Gynecology of Semmelweis University Faculty of Medicine between 1990 and 2000. MATERIALS AND METHODS: Between 1990 and 2000, 163 patients with epithelial ovarian tumors were diagnosed and treated. Of these, 27 patients were diagnosed as having low malignant potential (LMP) ovarian tumors. The authors evalutated the effect of histopathologic parameters (histologic type, grade of nuclear atypia, tumor size and tumor growth on the ovarian surface) and clinical parameters (age at diagnosis, stage of disease, and treatment modalities) on prognosis in this group of patients with a long observation time. We reviewed our experience to assess the safety of conservative surgical management of patients younger than age 40 with early stage disease, and to determine the long-term outcome of low malignant potential ovarian tumors. Medical records were reviewed on all 27 patients to determine age, gravidity, size of tumor, bilaterality, sites of extraovarian involvement, stage of disease and the operative procedure. Follow-up information was obtained from hospital records, and in some cases, by direct patient contact. Statistical comparisions were made by the chi2 test. RESULTS: The incidence of LMP tumors in our patient population was 16.5%. The patients ranged in age from 15 to 82 years (median, 45 years). The lesions were staged according to FIGO. The stage distribution was Stage IA in 20 patients, Stage IB in one patient, Stage IC in one patient, Stage IIA in one patient, Stage IIB in one patient, Stage IIC in one patient and Stage IIIA in two patients. The ovarian tumors ranged in size from 3 to 19 cm (median 9 cm) and 15% of the tumors were bilateral. All patients with LMP ovarian tumors were treated with primary surgery; those who were older than 40 (14 patients) were treated with total trans-abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH and BSO), while patients younger than 40 with early stage disease (12 patients) who wished to retain their fertility potential were treated with fertility-sparing surgery, namely unilateral salpingo-oophorectomy (USO). One patient who was younger than 40 with a Stage IIIA LMP ovarian tumor was also treated with TAH and BSO. Follow-up information was available for all 27 patients with LMP ovarian tumors. Only those patients with a minimum of two years of follow-up were included. Follow-up information from two to ten years (median, 6 years; mean, 6.5 years) revealed that all 27 patients were alive. During the period of follow-up one patient who initially had stage IIIA disease developed recurrent tumor. Fifty percent of patients who underwent conservative fertility-sparing surgical treatment (6/12) subsequently conceived. CONCLUSIONS: This study confirms the excellent prognosis for patients with low malignant potential ovarian tumors. Conservative fertility-saving surgical treatment can be offered to young patients (< 40 years) with early stage (stage I-II) disease who wish to retain their fertility potential. Up to 50% of women in this study who underwent conservative surgery subsequently conceived. The long-term outcome of LMP ovarian tumors is extremely favorable, even when long-term follow-up is extended to ten years.
