Study of Factors that Influence Sentinel Lymph Node Identification and Detection Rate in Cervical Cancer of Uterus / 대한산부인과학회지

OBJECTIVE: The purpose of this prospective study was to determine the feasibility of sentinel lymph node (SN) identification and to evaluate the factors that influence the sentinel node detection rate in patients with cervical cancer of the uterus. METHODS: Forty three patients underwent intracervical injection of 1% isosulfan blue dye at the time of planned radical hysterectomy and lymphadenectomy between January 2003 and July 2003. With visual detection of blue nodes, SNs were identified and separately removed. And then all patients underwent complete pelvic lymph nodes dissection and/or para-aortic lymph nodes dissection. If frozen sections of the lymph nodes were negative, radical hysterectomy was performed. Tumor characteristics, surgical findings, specific locations of SN and final pathologic results were recorded and correlated with final pathologic results. RESULTS: The mean age of patients was 49.3 years (30-78). SNs were identified in 23 of 43 (53%) patients. About 48.7% of SNs were found in the external iliac region, 31.7% in the obturator region, 17.0% in the internal iliac region and 2.4% in the common iliac region. Metastatic nodes were detected in 11 of 43 (26%) patients. Among 23 patients whose SNs were detected, 5 patients had metastatic nodes while among 20 patients whose SNs were not detected, 8 patients had metastatic nodes. No false negative SN results were obtained. Successful SN detection was more likely performed in patients with preoperative conization (P=0.0156). However, age, stage, histologic type, operation type, and neoadjuvant chemotherapy did not show any significant differences in SN detection rate. CONCLUSION: The identification of the SN with isosulfan blue dye is feasible and safe. SN detection rate was high in patients with preoperative conization. But low detection rate should be further investigated.

Mucinous Borderline tumor associated with Mature Cystic Teratoma of Ovary / 부인종양

OBJECTIVE: To evaluate the clinicopathological characteristics of mucinous borderline tumor associated with mature cystic teratoma and the origin of its cell type. METHODS: Five patients who were diagnosed as mucinous borderline tumor associated with mature cystic teratoma and treated in Samsung Cheil Hospital from January 1996 to September 2004 were analyzed. In addition MEDLINE, other data bases in English as well as in Korean revealed two more cases. We analyzed the result with patient's characteristics, preoperative symptoms, mass sizes, serum CA-125, operative procedure, stages, recurrence and survival period. Histological slides of the specimens were analysed for expression of cytokeratin (CK)-7 and cytokeratin (CK)-20 by immunohistochemical staining to know the origin of the cell. RESULTS: The mean age was 45 years (25-61 years). Preoperative symptoms were palpable abdominal mass, abdominal pain and urinary frequency. The mean level of CA-125 was 46.05 U/mL and the mean tumor size was 16.75 cm (8.8-22.0 cm). Post surgical FIGO staging was; stage Ia in 6 cases, stage Ic in 1 case. Four cases were CK7(-)/CK20(+), reflecting gastrointestinal origin, and also showed pattern of pseudomyxoma peritoneii. Mean survival period was 32.7 months (6-67 months) without evidence of recurrence, except one case. CONCLUSION: Our findings suggest that mucinous borderline tumor associated with mature cystic teratoma, is diagnosed at relatively young age and early stage, associated with good prognosis.

Clinical Outcomes of Patients treated for Cervical Pregnancy with or without Methotrexate

The objective of this study is to describe the clinical outcomes of patients treated for cervical pregnancy with or without methotrexate (MTX) and to evaluate the effects of MTX in the treatment of cervical pregnancy. Between January 1993 and February 2000, 31 patients were diagnosed with cervical pregnancy. Twenty-two patients were treated with MTX chemotherapy and nine patients were treated with surgical procedures without MTX treatment. In the non-MTX treatment group, three patients underwent total abdominal hysterectomy, five required adjuvant procedures to control the bleeding during dilatation and curettage (D&C) and only one patient was treated with a simple D&C. In the MTX treatment group, fourteen (63.6%) patients were treated with only MTX and eight (36.4%) cases underwent concomitant procedures (simple curettage, curettage and Foley catheter tamponade, cer-vical cerclage, ligation of the descending branches of uterine arteries, or ligation of hypogastric arteries). The uterus was preserved in all cases and three women delivered healthy babies in their subsequent pregnancy. In conclusion, early diagnosis, appropriate MTX regimen in combination of necessary adjuvant conservative procedures could contribute to successful treatment with preservation of the uterus and future reproductive ability.

Sensitivity of AutoPap Primary Screening System with Location-Guided Screening in Uterine Cervical Cytology / 대한세포병리학회지

OBJECTIVE: The sensitivity of the AutoPap Primary Screening System with Location-Guided Screening (AutoPap LGS) for identifying atypical cells in cervicovaginal smears was evaluated. METHODS: Two hundred forty one slides with atypical cervical cytology randomly sampled were rescreened both manually and by the AutoPap LGS. The AutoPap LGS localized the atypical cells as 15 fields of view(FOVs), which were reexamined by manual review. The sensitivity was also evaluated in accordance with the cellularity of the smears. RESULTS: The AutoPap LGS successfully processed 232 out of 241 slides. The sensitivity of the AutoPap LGS identifying the atypical cells in successfully processed slides was 97.4%(226/232). The false negative rate was 2.6%(6/232). There was no false negative case in high grade squamous intraepithelial lesion (HSIL) or squamous cell carcinoma(SCC) smears in the AutoPap LGS. The FOVs localized the diagnostic-atypical cells in 97.8%(221/226). The number of diagnostic-atypical FOVs was increased in higher-degree of atypical cytology. The AutoPap LGS localized the atypical cells in 100% of adequately cellular smears and in 92.5% even in low cellular smears. CONCLUSION: The AutoPap LGS showed relatively good sensitivity to detect atypical cells. It can be a valuable system to localize atypical cells, especially in HSIL or cancer slides, even in smears with low cellularity.

Preoperative Pap Smears in Endometrial Carcinoma: The Clinicopathologic Relevance / 대한산부인과학회잡지

OBJECTIVE: The aim of this study was to evaluate the correlation between preoperative Pap smears and known poor prognostic factors in patients with endometrial carcinoma. METHODS: Between January 1989 and June 2000, preoperative evaluation of Pap smears were done in 163 patients with endometrial carcinoma who underwent total abdominal hysterectomy with bilateral salpingo- oophorectomy, peritoneal cytology, and pelvic and/or para-aortic lymphadenectomy. All Pap smears and histologic sections were reviewed. Pathologic parameters of hysterectomy specimens were evaluated and correlated with the findings of Pap smears. Chi-square test was used for statistical analysis. p-values<0.05 were considered significant. RESULTS: The mean age of patients was 49 years with range between 24 and 75 years old. 72 patients (44.2%) had normal, 38 patients (23.3%) had atypical glandular cells of undetermined significance (AGUS), and 53 (32.5%) had adenocarcinoma on preoperative Pap smears. Statistically significant associations were found between Pap smears and age (p=.014), histologic grade (p=.000), cervical involvement (p=.015), depth of myometrial invasion (p=.000), lymph-vascular space invasion (p=.000), and surgical stage (p=.049). Patients with malignant cytology were more likely to have older age, poorly differentiated malignancies, deeper myometrial invasion, cervical metastases, lymphvascular invasion and higher surgical stage. However, histologic subtypes (p=.328), peritoneal cytology (p=.067), adnexal involvement (p=.602) and pelvic and/or para-aortic lymph node metastases (p=.266 and p=.220) were not statistically significant. CONCLUSION: This study revealed that preoperative abnormal Pap smears in patients with endometrial carcinoma were significantly associated with age, histologic grade, cervical involvement, depth of myometrial invasion, lymphvascular space invasion and surgical stage. Therefore, Pap smears could be an important part of the preoperative evaluation in patients with endometrial carcinoma.

Primary Invasive Carcinoma of the Vulva: A Clinical Review / 대한산부인과학회잡지

OBJECTIVE AND METHOD: Vulvar cancer is known to be a relatively rare malignancy among female population. Because of rare incidences and poor interests in malignancy of female genital tract, no sufficient clinical study has been accomplished and therefore clinical significance underestimated. However, a recent increase of vulvar cancer rate receives more attention because of the rapid growth in senile female population, such lesion becomes more accessible and thus early detection and treatment are highly required. In this report, we have investigated a retrospective clinical study on 13 patients diagnosed as primary invasive vulvar carcinoma at Samsung Cheil Hospital from 1988 to 2000. RESULTS: The mean age was 54.0 years (40-68). The most common symptom was found to be a palpable mass (92.3%). The lesion was observed mostly in labia minora (38.5%), followed by labia majora (30.8%) and clitoris (15.4%). Of 61.5% of the patients, a left-sided tendency in the occurrence of the lesion was noticeable. Among the patients who underwent surgery, stage II (55.5%) and histopathologically squamous cell carcinoma (69.2%) was dominant. Surgical complications were noted at 55.5% but no death was reported. There were 3 cases with invasion of the margin and 2 cases with radiotherapy and 1 case with chemotherapy. Mean follow-up was 56.9 (18-160) months and no deaths were reported during the follow-up. Recurrence was observed in only one case after 20 months of surgical operation. CONCLUSIONS : To decrease morbidity without compromising survival, a more conservative surgery should be considered for the management of selected patients with primary invasive vulvar cancer.

Clinical diversity of struma ovarii / 대한산부인과학회잡지

OBJECTIVE: The aim of our study was to evaluate the clinical, laboratory, and sonographic charac- teristics of struma ovarii. METHODS: Thirty three cases of struma ovarii were reviewed retrospectively over recent 5 years (1997- 2001). The presenting clinical, radiological, and pathological features of patients with consequent struma ovarii were compared, retrospectively. RESULTS: The mean age of the patients was 40.5 years (20-70). Eight women (24.2%) were postmenopausal. The mean tumor diameter was 7.6 cm (1.5-15) and occured more frequently (60.6%) in the right ovary. Ascites was present in 11 cases. The CA-125 level was normal in 30 cases and significantly increased in 3 cases. Fourteen patients had pelvic pressure symptoms such as lower abdominal discomfort or pain, lumbago, and some of these patients were examined because of irregualr vaginal bleeding. In asymptomatic 19 patients, the ovarian tumor was an incidental finding on routine examination. Although one of the patients had cervical thyroid nodule, preoperative and postoperative evidence of hyperthyroidism was not noted and any patients did not complained symptoms of hyperthyroidism. All of the tumors were diagnosed as benign on permanant pathology and only surgical excision was done as a definitive treatment. CONCLUSION: The presented clinical, laboratory and radiological features of patients with consquent struma ovarii were diverse. The diagnosis was only made later by strict pathological criteria and conservative treatment by tumor excision only may be sufficient.

Laparoscopically assisted surgical staging in endometrial cancer / 대한산부인과학회잡지

This paper reports our experiences in laparoscopically assisted surgical staging (LASS) to manage the patients with early-stage endometrial cancer. From March 1996 to March 1999, we performed LASS in 6 patients with clincal stage I adenocarcinoma of the endometrium. We performed laparoscopic-assisted vaginal hysterectomy (LAVH) with bilateral salpingo-oophorectomy (BSO) and intraoperative frozen-section (IFS) diagnosis. The depth of myometrial invasion, tumor differentiation, histologic types, cervical invasion, and adnexal involvement were determined by IFS diagnosis. Laparoscopic pelvic and/or para-aortic lymphadenectomies were performed based on the grade of the tumor and depth of myometrial invasion. One patient was discovered to have tumor metastases in pelvic peritoneum and uterosacral ligaments, and underwent only para-aortic lymphadenectomy for determining field of radiation therapy. 2 out of 5 patients only underwent LAVH with BSO and peroitoneal washing cytology. Three other patients underwent LAVH with BSO, peritoneal washing cytology and pelvic lymphadenectomy because they were identified by IFS diagnosis as intermediate risk group for nodal metastasis. The mean age of the patients was 46.4 years. Total length of the operation time ranged from 100 minutes to 305 minutes and the mean was 187.5 minutes. The mean hemoglobin decrement after the surgery was 0.9 gm/dl. No one recieved blood transfusion. The average number of pelvic and para-aortic lymph nodes removed were 16.7 and 18, respectively. After the surgery, the patients passed gas after an average of 2.0 days and urinated urine after an average of 3.8 days. No one had complication after LASS. Based on our experiences, LASS might be an alternative to the traditional surgical approach in patients with early-stage endometrial carcinoma.

False Negative Rate of Cervical Cytology Using the Autopap 300 QC System in Rescreening Modality / 대한부인종양콜포스코피학회잡지

OBJECTIVES: To estimate false-negative rate of cervical smears using Autopap 300 QC system in rescreening modality. METHODS: From September 1997 to December 1997, Total 26,983 cervical smears were obtained and 18,592 cervical smears were rescreened by Autopap 300 QC system with 10% review rate. The 274 cases of total 26,983 cervieal smears were confirmed histologically by colposcopic biopsy, cone biopsy and hysterectomy. The 274 cases of cervical smears, which obtained prior to pathologic diagnosis made, were evaluated based on cyto-histologic correlation and then the false negative rate were estimated. The cervical smears were reviewed, researching for the cause of false negative. RESULTS: (1) Histologic diagnosis of 274 cases include 65 cases of Low SIL, 173 cases of High SIL, 29 cases of SCC, 2 cases of adenocarcinoma in situ, and 5 cases of invasive adenocarcinoma. (2) The false negative rate were 3% (9/274). Those were 6.2%(4/65) of LSIL, 2.3% (4/173) Of HSIL, none of SCC and AIS, and 20%(5/1) of invasive adenocarcinoma. (3) The false negative cases were reviewed. The 6 cases were sampling enor and 3 cases were screening error. CONCLUSION: Using AutoPap 300 QC system in rescreening modality, The false negative rate of cervical smears were decreased, compared with our previous study.

Mapping of Multiple Genetic Alteration Sites of Cervical Carcinomas by Comparative Genomic Hybridization / 대한부인종양콜포스코피학회잡지

Comparative Genomic Hybridization (CGH) is a recently developed molecular cytogenetic technique, which makes it possible to detect chromosomal alteration in solid tumors. To determine whether chromosome alterations are related to cervical carcinoma, we have analyzed 33 cases (24 squamous cell carcinomas and 9 adenocarcinomas, stage Ib-IIIb) from tumor tissues and paraffin embedded tissues by CGH. The cut off value of CGH profiles was 1.15 and 0.85 (green/red ratio). Chromosomal aberrations were detected in 30 out of 33 cases (90.9%). In 32 cases, chromosome 3q was most frequently affected and had greater copy numbers in 20 of tbe 33 cases (60.6%). Interestingly, out of those 20 cases, 10 cases were shown to have a high-level of amplification of chr 3q. In addition to chr 3q, chromosomal gains were observed in chr 1q, 1p, 5p, Sq, 12p, 15q, 19q, 20q, Xp, and Xq. Furthermore chromosomal loss was detected, most commonly in chromosome 11q (11/33). Although less frequent, common losses were also detected in chr 2q, 4p, 4q, Sq, 1 1p, 17p, and 18p. In addition, there were cases of gross chromosome loss for chr 4, 6, 10, 11, 13, 14, 16, 17, 18, 19, 20, 21, 22 and X. In cases involving whole arm deletion, we utilized fluorescence in situ hybridization (FISH) using specific probes a-satellite. We performed HPV typing for 16 and 18 usiag polymerase chain reaction (PCR) and Southem blot analyses. Out of 33 tumor samples, 24 cases (72,7%) were HPV 16 positive, while only 6 cases were positive for HPV 18. two cases were positive for both HPV 16 and 18. We believe that a gain of chromosome 3q as a reeurrent chromosomal aberration may contribute to the tumorigenesis of cervical cancer. However, we could not correlate a pattern of chromosomal aberration with tumor stage or histologic type in cervical cancer.

Clinicopathologic Analysis of Four Cases of Primary Ovarian and Parovarian Transitional Cell Carcinoma / 대한부인종양콜포스코피학회잡지

Four cases of primary transitional cell carcinoma (TCC) arising in the ovary (3 cases) and the parovarium (1 case) were collected for clinicopathologic analysis. The mean age was 46.2 years (range, 39-57 years). Two patients complained abdominal discomfort and vaginal discharge, respectively. Other 2 cases were incidentally found from routine check. Grossly, the tumors were solid and cystic (2 cases), solid (1 case) and surface papillary growth on capsule (1 case). Microscopically, the tumor showed almostly same to the histologic features of TCC of urinary bladder. Three cases were pure TCC, and one was mixed TCC and serous carcinoma. FIGO stage were 1 IIa, 2 IIc, and 1 IIIc. Treatment was surgery with adjuvant chemotherapy. Two patients are alive with no evidence of disease, and two have lung or brain metastasis.

Association Between Apoptosis and Development of the Cervical Neoplasia / 대한부인종양콜포스코피학회잡지

Apoptosis, including the programmed cell death, is important event in normal cell turnover and maintenance of adult tissues. Apoptosis exerts a homeostatic function in relation to tissues dynamics, as the steady state of continuously renewing tissues achieved by a balance between cell replication and cell death. This study was undertaken to investigate the association between apoptosis and development of the cervical neoplasia. Archival cervical samples from normal epithelium (n 10), low-grade squamous intraepithelial lesions (LSIL, n = 10), high-grade squamous intraepithelial lesions (HSIL, n 10), microinvasive squamous cell carcinomas (n 10), and invasive squamous cell carcinomas (n = 10) were evaluated for apoptosis. We used in situ end-labeling of DNA strand breaks by terminal deoxynucleotidyltransferase incorporation of biotinylated deoxyuridine to 3-OH ends of DNA, identified by nickel-avidine-peroxidase. The apoptotic index (sum of apoptotic bodies divided by the total nuclei times 100) significantly decreased (P<0.05) as the degree of neoplasia increased: 3.1 + 0.9 % in normal epithelium, 5.5 +/- 1.4 % in LSIL, 1.6 +/- 0.4 % in HSIL, 1.9 +/- 0.5 % in microinvasive carcinomas, and 0.6 +/- 0.3 % in invasive carcinomas. Compared to normal epithelium, the total cell number per 200x field increased significantly (P<0,05): 379 +/- 47 in normal epithelium, 462 +/- 228 in LSIL, 670+/-293 in HSIL, 1035 +/- 254 in microinvasive carcinomas, and 1389 +/- 247 in invasive carcinomas. Consequently, these results suggest that progession of cervical carcinogenesis is associated with a decrease in apoptotic index and an increase in the number of the total cell.

Clinical Experience and Sensitivity of the AutoPap 300 QC System in Cervicovaginal Cytology / 대한세포병리학회지

OBJECTIVE: False negatives of cervical smears due to screening errors pose a significant and persistent problem. AutoPap 300 QC System, an automated screening device, is designed to rescreen conventionally prepared Pap smears initially screened by cytotechnologists as normal. Clinical experience and sensitivity of the AutoPap 300 QC System were assessed and compared with current 10% random quality control technique. MATERIALS AND METHODS: In clinical practice, a total of 18,592 "within normal limits" or "benign cellular changes" cases classified by The Bethesda System were rescreened by the AutoPap System. In study for sensitivity of The AutoPap System to detect false negatives, a total of 1,680 "within normal limits" or "benign cellular changes" cases were rescreened both manually and by the AutoPap System. The sensitivity of the AutoPap System to these false negatives was assessed at 10% review rate to compare 10% random manual rescreen. RESULTS: In clinical practice, 38 false negatives were identified by the AutoPap System and we had achieved 0.2% reduction in the false negative rate of screening error. In study for sensitivity, 37 false negatives were identified by manual rescreening, and 23 cases(62.2%) of the abnormal squamous cytology were detected by the AutoPap System at 10% review rate. CONCLUSONS: The AutoPap 300 QC System is a sensitive automated rescreening device that can detect potential false negatives prior to reporting and can reduce false negative rates in the laboratory. The device is confirmed to be about eight times superior to the 10% random rescreen in detecting false negatives.

Prediction and Clinical Evaluation of Hyperstimulation Syndrome / 대한산부인과학회잡지

OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is one of the well known complication of conttolled ovarian hyperstimulation. Though there have been numerous protocols for the prevention of OHSS, it has not been completely preventable until now. This study was performed to identify clinical predictors for early and late OHSS. METHODS: A retrospective analysis of all IVF cycles in 1993 up to June 1996 was performed. OHSS was diagnosed using the criteria of Rabau modified by Schenker. All cases of OHSS reported in this study presented with marked ovarian enlargement, ascites, oliguria, hemoconcentration and electrolyte disturbance. Ovarian stimulation was carried out using a combination of gonadotrophin releasing hormone-agonist, follicle-stimulation hormone and human menopausal gonadotrophin. 27 patients has moderate or severe OHSS presenting 3-7 days post-human chorionic gonadotrophin (hCG), and 21 patients had severe OHSS presenting 12-17 days post-hCG. RESULTS: No patient with early OHSS went onto develop late OHSS, and no patient with late OHSS had demonstrated early OHSS. Logistic regression showed that early OHSS was predicted by the number of oocytes retrieved and the estradiol concentration on the day hCG injection (P<0.05). Late OHSS was predicted by the transferred embryos, B-hCG on 14 day after hCG injection (P<0.05). CONCLUSION: Early OHSS was an acute effect of the hCG administered prior to egg retrieval in women with high estradiol and large number of retrieved oocytes. Our analysis of the risk factors for early OHSS indicates that cryopreservation of all embryos will not alter the risk of early OHSS even though it should prevent late OHSS. Late OHSS was induced by the rising serum concentration of hCG produced by the early pregnancy, the number of transferred embryos must be adjusted carefully, since it was associated with multiple gestation.

Clinical Evaluation of Follow-Up Methods and Results of Atypical Glandular Cells of Undetermined Significance (AGUS) on Cervicovaginal Pap Smears / 대한부인종양콜포스코피학회잡지

OBJECTIVE: To evaluate the efficacy of the follow up methods and results of AGUS detected on cervicovaginal Pap smears. METHODS: From May 1991 to December 1996, we have performed 407,451 cervicovaginal Pap smears, of which 326 patients were identified as AGUS. Out of them, 268 patients were followed by repeated Pap smears, colposcopy, cone biopsy or endometrial curettage. RESULTS: The incidence of AGUS on Pap smears is approximately 0.08%. The mean patient age was 43 years (range 22~79 years). The most common complaint was abnormal vaginal bleeding. The gross findings of the cervix were normal or mild erosion. The past histories of patients that could effect the AGUS results on Pap smears were as follows: 30 had cone biopsy, 21 had Pap smear on pregnancy or within 8 weeks after delivery, 3 had hormone replacement therapy, 2 had intrauterine device for contraception, and 5 were in the process of a follow up after a treatment of cervical cancer. The benign lesions detected during follow up periods were 6 microglandular hyperplasia of the cervix, 5 atypical squamous metaplasia of the cervix, 2 cervical endometriosis, 2 tubal metaplasia, 10 cervical myoma, 11 cervical polyp, 9 endometrial polyp, 3 uterine myoma, 1 pelvic endometriosis, 1 ovarian endometriosis, and 4 uterine adenomyosis. The premalignant or malignant lesions of the cervix were 4 low grade squamous intraepithelial lesion, 24 high grade squamous intraepithelial lesion, 8 glandular atypia/dysplasia, 5 adenocarcinoma in situ, 3 microinvasive denocarcinoma, and 4 invasive adenocarcinoma. The neoplastic lesions of the uterus were 6 endometrial hyperplasia, 11 endometrial adenocarcinoma, 1 malignant mixed M?lerian tumor, and 1 metastatic endometrial adenocarcinoma. Sixty seven (25%) among 268 patients followed up were identified to have clinically significant lesions of the cervix or uterus. The detection rates of abnormal lesions were 3.1% with repeated Pap smears (3/98), 28.4% with colposcopy-directed biopsy (31/109), 63.6% with cone biopsy (35/55), and 29.7% with endometrial curettage (19/64). CONCLUSION: AGUS on Pap smears showed various benign and malignant lesions of the cervix or uterus. The clinicians must communicate with the pathologists regarding the clinical informations of the patient as well as the origin of atypical glandular cells in Pap smears. We recommend that the patients with AGUS on Pap smear should undergo immediate intensive diagnostic studies, including colposcopy with endocervical curettage or cone biopsy in order to detect the lesion of the cervix and endometrial curettage in order to detect the endometrial lesions.

Comparative Study of Perinatal Outcome and the Incidene of Congenital Anomalies of Babies Born after Intracytoplasmic Sperm Injection (ICSI) and Conventional In-vitro Fertilization (IVF) / 대한불임학회지

The safety of ICSl as a novel procedure of assisted fertilization may be assessed by the health of the baby born. In order to evaluate the safety of ICSI, perinatal outcome and congenital anomaly of the babies born after ICSI were compared with those of babies born after IVF (control group). We analysed the clinical data from the obstetric and pediatric records, including the information obtained through telephone. The results are as follows; Mean gestaional age (+/-SEM) and birth weight in singleton pregnancy were 38.8+/-1.9 weeks and 3209.7+/-501.9gm in IVF group, 39.0+/-2.2 weeks and 3289.9+/-479.5gm in ICSI group, respectively. Mean gestational age and birth weight in twins were 36.8+/-2.1 weeks and 2512.8+/-468.0gm in IVF group, 36.5+/-2.8 weeks and 2492.7+/-537.1gm in ICSI group. In IVF group, perinatal mortality rates were 8.5 in singletons and 56.6 in twinst for the ICSI singletons and ICSI twins, the perinatal mortality rates were 11.6 and 49.0, respectively. The incidence of congenital malformations was 3.6% (8/224) in IVF group and 2.1% (4/188) in ICSI group, there was no statistical difference (p>0.05, Fisher's exact test). The incidence of major congenital anomalies was 0.9% (2/224; pulmonary artery hypoplasia, renal cystic dysplasia) in IVF group and 1.1% (2/188; holoprosencephaly, Cri du chat syndrome) in ICSI groups (p>0.05, Fisher's exact test). Similarly, there was no significant difference in incidence of minor congenital anormalies 2.7% (6/224) in IVF group and 1.1% (2/188) in ICSI group respectively (p>0.05, Fisher's exact test). In conclusion, there was no difference in the perinatal outcome and the incidence of congenital anomalies between the babies born after ICSI and those after conventional IVF.

Reproductive Outcome of Women with Recurrent Abortions or Infertility Following Treatment by Operative Hysteroscopy for an Intrauterine Septum / 대한산부인과학회잡지

Uterine anomalies have been reported in 4% of women with infertility and in up to 15% of those with recurrent abortion. One of the major intrauterine disorder associated with infertility and recurrent abortions is intrauterine septum, The reproductive outcome of 41 patients of intrauterine septum (7 complete, 34 incomplete) with repeated abortions or infertility was assessed after the uterine septotomy. 5 of 7 patients with comlete uterine septum undergone uterine septotomy (3; hysteroscopic metroplasty, 2; abdominal metroplasty) had total 6 pregnancies and all of them had live biths. 28 patients with incomplete uterine septum got the hysteroscopic intrauterine septotomy and the viable pregnancy rate was 62% (3 ongoing pregnancies, 13 live biths of total 26 pregnancies). 6 patients with incomplete uterine septum had not the operation and 5 patients had 5 live births after total 6 pregnancies with 1 spontaneus abortion. Even though, the number of cases were small, the live birth rate in the group of septotomy of the patients of complete uterine septum (100%, 6/6) was higher than that in the group of not-done (50%, 1/2). The live birth rate in the group of not-done of the patients with incomplete uterine septum (83%, 5/6) was higher than that in the group of hysteroscopic uterine septotomy (62%, 16/26), but 5 of 6 had short uterine septal length (<1 cm), 1 had 1.5 cm septal length in the group of not-done. All the patients with successful pregnancy outcome had no other co-factors at the diagnostic laparoscopy, but the 5 primary infertility patients with no live birth even after treatment (all were with incomplete septum; 3 undergone hysteroscopic septotomy, 2 not-done with one abortion) had other co-factors such as endometriosis, peritoneal or tubal facor. In conclusion, hysteroscopic uterine septotomy would be useful for the patients with habitutal abortion or infertility and more advanced managemnet protocols should be applied to the patients having other co-factors if there was no pregnancy even after the uterine septotomy.

Th1 Cytokine ( IFN-gamma ) Secretion Pattern of Peripheral Blood Mononuclear Cells Response to Trophoblast Antigen in Women with Unexplained Recurrent Spontaneous Abortion and Normal Fertile Controls / 대한산부인과학회잡지

OBJECTIVE: A dichotomous Thl and Th2 cytokine profile has been associated with reproductive failure and success, respectively. The purpose of our study was to determine the levels of Thl cytokine (IFN- y ) secreted by peripheral blood mononuclear cells (PBMCs) form women with unexplained recurrentabortion (URA) and fertile controls in response to trophoblast antigen. METHODS: PBMCs were isolated from 30 nonpregnant women with URA and from 10 nonpregnant fertile controls. Following 4 days of culture (1 * 10(6) cells/mL) with and without a protein extract derived from a trophoblast cell line (30 ug/mL, protein). None of the women had allergies, atopy or recent infection. Cytokines were measured in supernatants with enzyme-linked immunosorbent assay (ELISA) kits. IFN- r kit was obtained from BOISOURCE (lower limit of sensitivity, 15.6 pg/mL for IFN- r ). All values below the lowest limit of sensitivity as determined by test kit standards were considered negative. The cytokine stimulation test is considered positive if the IFN- r concentration increases by 200% or more with the trophoblast antigen stimulation. Datas are presented as mean+ SEM. Nonparametric testing (Mann-Whitney U) was used for analysis with P<0.05 considered statistically significant. RESULTS: The Thl-type cytokine (IFN- r ) was detected in 20(67%) of 30 supernatants from women with URA. In contrast, 2 (20%) of trophoblast-activated PBMC culture supernatants from the 10 parus women with normal reproductive histories was detected IFN- r and but were significantly lower than levels in women with URA who had secreted IFN- r upon trophoblast stimulation (99.80+ 18.17 pg/mL versus 166.47 + 36.96 pg/mL, p<0.05). Spontaneous secretion of IFN- r was significantly higher in culture supernatants from women with URA than in supernatants from women with successful reproductive histories (41.36.09+6.99 pg/mL versus 25.89+9.34 pg/mL, p<0.05). CONCLUSION: These data indicate that there are significant differences between women with URA and women with normal reproductive histories in their regulation of the Thl-cytokine (IFN- r) in response to trophoblast. Thl-type immunity to trophoblast is associated with URA and may play a role in reproductive failure.

Clinical Evaluation of Women with Low Grade Squamous Intraepithelial Lesion on Pap Smears / 대한부인종양콜포스코피학회잡지

The purpose of this study was for clinical evaluating those women with low grade squamous intraepithelial lesions (LSIL) who have been detected on Pap smears. We analyzed 279,270 Pap smears, from January 1994 to August 1997, of which 703 cases were identified as LSIL, and their medical records were reviewed retrospectively. Among them, 616 cases were able to follow-up by altered methods (repeated Pap smear only vs. histologic examination) and their efficacy for detecting more significant lesion (high grade squamous intraepithelial lesion: HSIL or invasive cancer) were also compared. The results were as follows; 1. The frequency of LSIL on Pap smears was approximately 0.25%. 2. The mean age was 39 years (range 18 ~70 years). 3. Most of the gross finding of the cervix were normal or mild erosion. 4. Most of symptom was asymptomatic, or nonspecific. 5. Eighty-seven women with LSIL on initial Pap smears, have performed repeated Pap smears. 74 (85.1%) was normal, 7 (8.0%) was ASCUS, 6 (6.9%) was LSIL. Remained 529 women had subsequently histologic examination such as colposcopic directed biopsy or cone knife biopsy. These histologic results showed 192 (36.3%) with normal, 258 (48.8%) with LSIL, 77 (14.6%) with HSIL, 2 (0.4%) with microinvasive carcinoma. Based on the results in this study, we emphasize the importance of regular screening procedures for early detection of cervical lesions because there was no specific clinical characteristics in women with cytologic diagnosis of LSIL. In addition, we recommened colpo-scopic directed biopsy or cone knife biopsy as follow-up evaluation method in women with LSIL on initial Pap smear for detecting more significant cervical lesion.
