A rare case of pure-type embryonal carcinoma in a 75-year-old woman mimicking epithelial ovarian carcinoma / 고신대학교의과대학학술지

Embryonal carcinoma, a very rare ovarian germ cell tumor, involves pure and mixed phenotypes. Pure-type embryonal carcinoma has never been reported in postmenopausal women. The current case was, thus, misdiagnosed as an epithelial ovarian carcinoma based on radiologic findings. Herein, we describe the case of ovarian embryonal carcinoma in a 75-year-old woman along with a literature review. Magnetic resonance imaging findings were suggestive of epithelial ovarian malignancy associated with endometrioma, including ureteral invasion. The patient underwent complete surgical staging, and a pathologic diagnosis of pure-type embryonal carcinoma was made. The patient’s postoperative course was uneventful, and adjuvant chemotherapy was administered. Embryonal carcinoma in the postmenopausal woman is a clinical challenge owing to the possibility of its misdiagnosis as epithelial ovarian carcinoma. To the best of our knowledge, this is the first report of pure-type ovarian embryonal carcinoma in a postmenopausal woman, with a description of the clinicopathologic characteristics and review of the relevant literature.

Observational Study for Adverse Effects and Discontinuation with Long-Term Post-Operative Hormonal Treatment for Endometriosis in Real-World Practice / 고신대학교의과대학학술지

Objectives@#To evaluate the side effects and causes of discontinuation of either combined oral contraceptives or dienogest (DNG) used to prevent recurrence in patients with surgically confirmed endometriosis. @*Methods@#We retrospectively analyzed the medical records of 213 women with endometriosis who had been treated with combined oral contraceptives (ethinyl estradiol 0.02 mg/drospirenone 3 mg [EE/DRSP]) or DNG 2 mg for 12 months or more. The side effects reported by the patients, laboratory parameters, causes of discontinuation of medication, and recurrence rates were evaluated one, two, three, four, and five years after starting medication (Y1, Y2, Y3, Y4, and Y5). @*Results@#EE/DRSP were administered to 59 patients, while DNG was administered to 154 patients. The mean durations of postoperative use of EE/DRSP and DNG were 44.5 ± 22.6 months and 23.6 ± 13.5 months, respectively. The prevalence of side effects was 27.1%, 19.0%, 10.0%, 10.5%, and 7.4% in the EE/DRSP group and 29.2%, 15.7%, 14.0%, 23.1%, and 0.0% in the DNG group at Y1, Y2, Y3, Y4, and Y5, respectively. The discontinuation rates were 1.7%, 1.7%, 4.0%, 0.0%, and 7.4% at Y1, Y2, Y3, Y4, and Y5, respectively, in the EE/DRSP group and 10.4%, 3.3%, 4.0%, 3.8%, and 0.0% at the same times in the DNG group. The recurrence rates were less than 4% in both the groups. @*Conclusions@#The side effects of commonly prescribed postoperative hormone treatments were relatively mild, and the occurrence of side effects decreased with continuous administration. Further, the long-term use of postoperative hormone treatments is likely to prevent recurrence of endometriosis after surgery.

Dietary pattern and risk of endometrioma in Korean women: a case-control study

Objective@#The aim of this study was to investigate and compare the dietary patterns of Korean women diagnosed with endometrioma or other benign ovarian cysts. @*Methods@#A total of 66 patients, comprising 39 patients who were surgically diagnosed with ovarian endometrioma and 27 control patients with other benign ovarian cysts, were included in this case-control study. Trained interviewers identified and interviewed the case patients and controls on the day before the laparoscopic ovarian surgery, using a semiquantitative food frequency questionnaire developed by the Ministry of Health and Welfare of Korea. Statistical analysis was performed using the Wilcoxon sum-rank test for continuous variables and the χ2 test or Fisher’s exact test for categorical variables. @*Results@#The calcium intake from daily food consumption was significantly lower in patients with endometrioma than in those with other benign ovarian cysts. The dietary intakes of vitamin D, iron, and zinc were also relatively lower in patients with endometrioma than in patients with other benign ovarian cysts, although they did not reach the statistical significance threshold. @*Conclusion@#The risk of endometrioma is significantly associated with a lower dietary intake of calcium. Future studies including a larger number of patients on a nationwide scale are urgently required for further clarification.

Clinical Usefulness of Cancer Antigen (CA) 125, Human Epididymis 4, and CA72-4 Levels and Risk of Ovarian Malignancy Algorithm Values for Diagnosing Ovarian Tumors in Korean Patients With and Without Endometriosis

BACKGROUND: Tumor markers are useful for detection and preoperative evaluation of ovarian tumors. We evaluated the clinical usefulness of cancer antigen (CA) 125, human epididymis 4 (HE4), and CA72-4 levels and Risk of Ovarian Malignancy Algorithm (ROMA) values for differential diagnosis of malignant and borderline tumors among suspected ovarian tumors, and the effects of endometriosis on these tumor markers. METHODS: In a total of 266 patients (213, 14, and 39 with benign, borderline and malignant tumors, respectively), CA125, HE4, and CA72-4 levels were measured, and ROMA values were calculated. Medians of each marker were compared among the three groups. The area under the ROC curve (AUC), sensitivity, and specificity were calculated to analyze the diagnostic performance of each marker. RESULTS: All markers were significantly higher in the malignant group than in the benign group. HE4 levels and ROMA values were significantly higher in the malignant group than in the borderline group. ROMA value had the highest AUC for distinguishing the malignant and borderline groups from the benign group in premenopausal (0.773) and postmenopausal (0.927) patients. CA125 level was significantly higher in patients with endometriosis than in those without (P<0.001), whereas HE4 and CA72-4 levels were not affected by endometriosis (P=0.128 and 0.271, respectively). CONCLUSIONS: ROMA value is the best marker to distinguish malignant and borderline tumors from benign tumors in pre- and postmenopausal patients. HE4 and CA72-4 levels provide information on possible CA125 elevation due to endometriosis.

Prognostic Significance of CD109 Expression in Patients with Ovarian Epithelial Cancer

BACKGROUND: Ovarian epithelial cancer (OEC) is the second-most common gynecologic malignancy. CD109 expression is elevated in human tumor cell lines and carcinomas. A previous study showed that CD109 expression is elevated in human tumor cell lines and CD109 plays a role in cancer progression. Therefore, this study aimed to determine whether CD109 is expressed in OEC and can be useful in predicting the prognosis. METHODS: Immunohistochemical staining for CD109 and reverse transcription-quantitative polymerase chain reaction was performed. Then we compared CD109 expression and chemoresistance, overall survival, and recurrence-free survival of OEC patients. Chemoresistance was evaluated by dividing into good-response group and poor-response group by the time to recurrence after chemotherapy. RESULTS: CD109 expression was associated with overall survival (p = .020), but not recurrence-free survival (p = .290). CD109 expression was not an independent risk factor for overall survival due to its reliability (hazard ratio, 1.58; p = .160; 95% confidence interval, 0.82 to 3.05), although we found that CD109 positivity was related to chemoresistance. The poor-response group showed higher rates of CD109 expression than the good-response group (93.8% vs 66.7%, p = .047). Also, the CD109 mRNA expression level was 2.88 times higher in the poor-response group as compared to the good-response group (p = .001). CONCLUSIONS: Examining the CD109 expression in patients with OEC may be helpful in predicting survival and chemotherapeutic effect.

Clinical and Genetic Characteristics of BRCA1/2 Mutation in Korean Ovarian Cancer Patients: A Multicenter Study and Literature Review / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: We investigated the clinical relevance and spectrum of BRCA1/2 mutations in Korean ovarian cancer (KoOC) patients. MATERIALS AND METHODS: Two hundred seventy-nine KoOC patients were enrolled from three university hospitals between 2012 and 2017. Their peripheral blood samples were obtained for BRCA1/2 mutation analysis by direct sequencing. Clinicopathological characteristics were retrospectively reviewed, and spectrum analyses of BRCA1/2 mutation were assessed by systematic literature review. RESULTS: Frequency of BRCA1/2 mutations was 16.5% in KoOC patients. BRCA1/2 mutations were significantly associated with family history of breast/ovarian cancer (pT of BRCA2 in KoBC). CONCLUSION: The clinical relevance of BRCA1/2 mutations in KoOC patients was confirmed but that of early age-of-onset was not. Possible inconsistency in the ratio of BRCA1-to-BRCA2 mutations and the most common mutation between KoOC and KoBC may probably suggest presence of mutation sequence-associated penetrance tendency in hereditary Korean breast and ovarian cancer. These data may provide insights for optimal genetic counseling and prophylactic treatment for at-risk relatives of KoOC patients.

Changing Trends in Pregnancy and Childbirth among Women Living with Human Immunodeficiency Virus at a Tertiary Hospital in Korea: A 28-Year Experience

BACKGROUND@#The reports about fertility desire and pregnancy outcome among women infected with human immunodeficiency virus (HIV) in Korea are scarce. This study aimed to determine the changing trend in pregnancy incidence among women infected with HIV in Korea.@*MATERIALS AND METHODS@#We retrospectively reviewed the medical records of women infected with HIV visiting Pusan National University Hospital between January 1990 and October 2018.@*RESULTS@#A total of 149 women with HIV infection visited the study hospital. Among them, 33 pregnancies in 24 (16.1%) women were identified. There were 17 live births (51.5%) and 13 abortions (39.4%), whereas 3 women (9.1%) were transferred to another hospital or were lost to follow-up. The number of live birth rose from 0 in 1990-1998 to 17 in 1999-2018. The proportion of repeated pregnancies after HIV diagnosis also increased steeply, from 14.3% in 1999-2008 to 50% in 2009-2018. However, the number of abortions also increased over time. There were 8 induced abortions, 7 (87.5%) of them were diagnosed with HIV infection during pregnancy and 3 (37.5%) were unplanned pregnancies. Eighteen babies, including 1 twin case, were born from 17 births. There was no mother-to-child HIV transmission in our study.@*CONCLUSION@#The number of pregnancies among women with HIV infection and repeated pregnancies after HIV diagnosis has been increasing in Korea, probably due to the desire of HIV patients to have more children. However, the number of abortions also increased, probably due to health concerns and uncertain pregnancy outcome.

The effect of tamoxifen therapy on the endometrium and ovarian cyst formation in patients with breast cancer

OBJECTIVE: To evaluate the effect of tamoxifen on female reproductive organs in women with breast cancer. METHODS: We retrospectively reviewed the medical records of 309 women with breast cancer who were currently receiving tamoxifen and undergoing regular gynecological examination. RESULTS: We evaluated 92 pre- and 217 postmenopausal women. The prevalence of endometrial thickening was 12% in the pre- and 10.6% in the postmenopausal group. An endometrial biopsy was performed in 43 women and confirmed endometrial cancer in 1, endometrial polyps in 14, and endometrial hyperplasia in 4 women. Transvaginal ultrasonography showed 25 cases of newly developed ovarian cysts. Most ovarian cysts had disappeared during follow-up. CONCLUSION: Tamoxifen use in women with breast cancer causes few complications and is considered safe for female reproductive organs in case of regular gynecological examination.

Cosmetic outcomes of cesarean section scar; subcuticular suture versus intradermal buried suture

OBJECTIVE: The objective of the study was to compare cosmetic outcomes and overall satisfaction rate of cesarean section scar between conventional subcuticular suture and intradermal buried vertical mattress. METHODS: Patients were enrolled to the study by chart review. A scar assessment was obtained retrospectively through a telephone survey. The patient component of the patient and observer scar assessment scale (POSAS) was utilized along with the overall satisfaction of the patient regarding their cesarean section scar and their willingness to choose the same skin closure technique when anticipating their next cesarean section. RESULTS: A total of 303 cases of cesarean section was recruited, 102 finished telephone surveys were calculated for the analyses. Subcuticular suture was regarded as control group (n=52) and intradermal buried suture as test group (n=50). The PSAS score of the test group (mean, 21.8) was lower than that of the control group (mean, 28), with a statistical significance (P=0.02). Overall satisfaction rate did not differ between the two groups. Two parameters of the PSAS score and the level of overall satisfaction showed significant correlation (Pearson's r, −0.63; P < 0.01). CONCLUSION: We suggested the use of intradermal buried vertical mattress as a cosmetically superior skin closure method for application in cesarean sections over subcuticular stitch.

Prognostic value of preoperative lymphocyte-monocyte ratio in elderly patients with advanced epithelial ovarian cancer

OBJECTIVE: To investigate the prognostic significance of preoperative lymphocyte-monocyte ratio (LMR) in elderly patients with advanced epithelial ovarian cancer (EOC) receiving primary cytoreductive surgery and adjuvant platinum-based chemotherapy. METHODS: A total of 42 elderly patients (≥65 years) diagnosed with EOC who are receiving primary cytoreductive surgery and adjuvant platinum-based chemotherapy from 2009 to 2012 was included. LMR was calculated from complete blood cell count sampled before operation. Receiver operating characteristic (ROC) curves were used to calculate optimal cut-off values for LMR. Prognostic significance with respect to overall survival (OS) and progression-free survival (PFS) were determined using log-rank test and Cox regression analysis. RESULTS: The optimized LMR cut-off value determined by ROC curve analysis was 3.63 for PFS and OS. The high LMR group (LMR ≥3.63) was found to be significantly more associated with optimal debulking (P=0.045) and platinum response (P=0.018) than the low LMR group. In addition, Kaplan-Meier analysis revealed the LMR-high group was significantly more associated with high PFS and OS rates (P=0.023 and P=0.033, respectively), and univariate analysis revealed that a high LMR, histology type, and optimal debulking and platinum responses were significantly associated with prolonged PFS and OS. However, subsequent Cox multivariate analysis showed only optimal debulking and platinum response were independent prognostic factors of PFS or OS. CONCLUSION: This study suggests that LMR might be associated with treatment and survival outcomes in elderly patients with EOC receiving standard oncology treatment.

Peptide YY producing strumal carcinoid tumor of the ovary in a postmenopausal woman: a rare cause of chronic constipation

Strumal carcinoid tumor of the ovary is a rare subtype of ovarian carcinoid tumors; it is characterized by an intimate mixture of thyroid and carcinoid tissues. We present a case of a 64-year-old woman who presented with the chief complaint of persistent, severe constipation for over 5 years; she was later found to have an ovarian strumal carcinoid tumor. Computed tomography showed a well-defined solid mass measuring 6.4 cm at the right adnexa. The patient underwent right salpingo-oophorectomy and was histopathologically diagnosed as having a strumal carcinoid tumor. Immunohistochemical examination showed immunoreactivity for peptide YY (PYY), which exerts an inhibitory effect on the peristaltic actions of the distal intestine. After surgery, the patient's constipation resolved rapidly, suggesting a correlation between PYY producing ovarian carcinoid tumor and constipation. This is the first case report of PYY producing primary strumal carcinoid tumor of the ovary associated with persistent, severe constipation from Korea.

Discovery of Splenic Sarcoidosis Concurrent with the Diagnosis of Ovarian Cancer: A Case Report

Sarcoidosis is a multisystem inflammatory disease of unknown etiology characterized by noncaseating epithelioid granuloma formation. Although the relationship between sarcoidosis and malignancy has been noted in recent decades, there are few case reports describing the concurrent diagnosis of sarcoidosis and malignancy. Herein, we describe a case of biopsy-proven splenic sarcoidosis mimicking metastasis at the time of ovarian adenocarcinoma. Imaging studies including positron-emission tomography-computed tomography were not useful for differentiating sarcoidosis from malignancy. Thus, our case highlights the importance of histopathological examination to rule out nonmalignant conditions before the diagnosis of metastatic disease is made.

Crucial role of HMGA1 in the self-renewal and drug resistance of ovarian cancer stem cells

Cancer stem cells are a subpopulation of cancer cells characterized by self-renewal ability, tumorigenesis and drug resistance. The aim of this study was to investigate the role of HMGA1, a chromatin remodeling factor abundantly expressed in many different cancers, in the regulation of cancer stem cells in ovarian cancer. Spheroid-forming cancer stem cells were isolated from A2780, SKOV3 and PA1 ovarian cancer cells by three-dimensional spheroid culture. Elevated expression of HMGA1 was observed in spheroid cells along with increased expression of stemness-related genes, such as SOX2, KLF4, ALDH, ABCB1 and ABCG2. Furthermore, spheroid A2780 cells, compared with adherent cells, showed higher resistance to chemotherapeutic agents such as paclitaxel and doxorubicin. HMGA1 knockdown in spheroid cells reduced the proliferative advantage and spheroid-forming efficiency of the cells and the expression of stemness-related genes. HMGA1 overexpression in adherent A2780 cells increased cancer stem cell properties, including proliferation, spheroid-forming efficiency and the expression of stemness-related genes. In addition, HMGA1 regulated ABCG2 promoter activity through HMGA1-binding sites. Knockdown of HMGA1 in spheroid cells reduced resistance to chemotherapeutic agents, whereas the overexpression of HMGA1 in adherent ovarian cancer cells increased resistance to chemotherapeutic agents in vitro. Furthermore, HMGA1-overexpressing A2780 cells showed a significant survival advantage after chemotherapeutic agent treatment in a xenograft tumorigenicity assay. Together, our results provide novel insights regarding the critical role of HMGA1 in the regulation of the cancer stem cell characteristics of ovarian cancer cells, thus suggesting that HMGA1 may be an important target in the development of therapeutics for ovarian cancer patients.

Ovarian Cavernous Hemangioma Presenting as a Large Growing Mass in a Postmenopausal Woman: A Case Report and Review of the Literature

Ovarian hemangiomas are usually of the cavernous type, and are rarely encountered. A 73-year-old woman presented with lower abdominal discomfort. Subsequent physical examination depicted a palpable mass in the lower abdomen. Abdominopelvic computed tomography (CT) revealed a well-circumscribed mass with thin septa measuring 12.1 x 9.0 cm in the right ovary. Levels of the tumor markers cancer antigen (CA)-125 and CA 19-9 were within the normal range. At laparoscopy, the tumor was found to be confined to the right ovary and to have a smooth surface. The final histopathological result was ovarian cavernous hemangioma. Microscopically, the mass consisted of multiple, dilated, blood-filled vascular channels separated by loose connective tissue, and all were lined by a single layer of flattened endothelium. The authors present a case of ovarian cavernous hemangioma presenting as a large growing mass in a postmenopausal woman and review previously published literature.

S100 expression in dendritic cells is inversely correlated with tumor grade in endometrial carcinoma

OBJECTIVE: The aim of this study was to determine the expression of S100 positive dendritic cells (DCs) and the relationship with clinicopathologic factors in endometrial carcinoma. METHODS: Samples were collected from 89 patients with endometrial endometrioid adenocarcinoma treated in Pusan National University Hospital from 2004 to 2011. Normal endometrial tissues were obtained from 30 hysterectomized women with benign adnexal masses and served as controls. Paraffin-embedded sections were immunohistochemically stained for S100 was performed, and the number of positive DCs was counted. The relationship of these cells to the stage, histological grade, myometrial invasion, and lymph node metastasis was analyzed. RESULTS: The proportion of S100-positive DCs in the endometrial endometrioid adenocarcinoma was 31.5% (28/89), which was significantly higher (P<0.05) than in the control group. The proportion of S100-positive DC expression was negatively correlated with the histologic grade, but was not associated with the stage, myometrial invasion, or lymph node metastasis. CONCLUSION: High DC density was inversely correlated with histologic grade in endometrial carcinoma. Tumor-infiltrating S100+ DCs may be used as pathologic marker in endometrial carcinoma.

Human Papillomavirus Prevalence and Genotype Distribution among HIV-Infected Women in Korea

The epidemiology on human papillomavirus (HPV) among human immunodeficiency virus (HIV)-infected women in Korea is not well established. A retrospective study was conducted to determine the prevalence and genotype distribution of HPV infection among HIV-infected women in Korea. HPV DNA genotype and cervical cytology were examined in 60 HIV-positive women and 1,938 HIV-negative women. HPV genotypes were analyzed by using a HPV DNA chip. HIV-infected women had higher prevalence of high-risk HPV (hr-HPV) infection (30% vs 4.9%, adjusted odds ratio [AOR], 6.96; 95% confidence interval [CI], 3.63-13.34, P<0.001) and abnormal cervical cytology (18.3% vs 1.8%, AOR, 10.94; 95% CI, 5.18-23.1, P<0.001) compared with controls. The most common hr-HPV genotype detected in HIV-infected women was HPV 16 (10%), followed by 18 (6.7%) and 52 (5%). Prevalence of quadrivalent vaccine-preventable types (HPV 6, 11, 16, and 18) was 21.7% and 2.3% in HIV-positive women and HIV-negative women, respectively. Age was a significant risk factor for hr-HPV infection in HIV-infected women (P=0.039). The presence of hr-HPV was significantly associated with abnormal cervical cytology (P<0.001). These findings suggest that HPV testing for cervical cancer screening in HIV-infected women would be necessary, particularly among young age group.

Tumor-infiltration of T-lymphocytes is inversely correlated with clinicopathologic factors in endometrial adenocarcinoma

OBJECTIVE: The aim of this study was to determine the distribution of T-lymphocytes and their relationship with clinicopathologic factors in endometrial carcinoma. METHODS: Samples were collected from 89 patients with endometrial endometrioid adenocarcinoma treated in Pusan National University Hospital from 2004 to 2011. Normal endometrial tissues were obtained from 30 hysterectomized women with benign adnexal masses and served as controls. Paraffin-embedded sections were immunohistochemically stained for CD8 (cytotoxic) and CD4 (helper) T-lymphocytes. The relationship of these cells with stage, histological grade, myometrial invasion, and lymph node metastasis was analyzed. RESULTS: The proportion of CD8+ and CD4+ lymphocytes in the endometrial endometrioid adenocarcinoma tissues was 67.4% (60/89) and 44.9% (40/89), respectively, which was significantly higher (P<0.05) than in the control group. The extent of CD8+ lymphocyte expression was negatively correlated with histologic grade, myometrial invasion, and lymph node metastasis. The proportion of infiltration of the CD4+ lymphocytes was negatively correlated with histologic grade and myometrial invasion. CONCLUSION: The high rate of infiltration of T-lymphocytes was negatively correlated with histologic grade, myometrial invasion, and lymph node metastasis. Our findings suggest that tumor-infiltrating T-lymphocytes may be used as pathologic prognostic factors in endometrial carcinoma.

The Role of TWIST in Ovarian Epithelial Cancers

BACKGROUND: Epithelial-mesenchymal transition (EMT) is associated with tumor hypoxia. EMT is regulated, in part, by the action of TWIST, which inhibits of E-cadherin expression and may interfere with the p53 tumor-suppressor pathway. METHODS: We examined the expression of TWIST, E-cadherin, hypoxia-inducible factor 1alpha (HIF1alpha), and p53 by immunohistochemistry in 123 cases of ovarian epithelial cancers (OEC) to evaluate the role of TWIST in OEC. We assessed the association between protein expression and clinicopathologic parameters. RESULTS: The expression of TWIST, E-cadherin, HIF1alpha, and p53 proteins was found in 28.5%, 51.2%, 35.0%, and 29.3% of cases, respectively. TWIST expression was associated with higher histologic grade and unfavorable survival. TWIST expression was correlated with HIF1alpha expression and reduced E-cadherin expression. The altered HIF1alpha/TWIST/E-cadherin pathway was associated with lower overall survival (OS), while the co-expression of TWIST and p53 was correlated with lower progression-free survival. In the multivariate analyses, TWIST expression was an independent prognostic factor for OS. CONCLUSIONS: Our data imply that TWIST expression could be a useful predictor of unfavorable prognosis for OEC. TWIST may affect the p53 tumor-suppressor pathway. Moreover, hypoxia-mediated EMT, which involves the HIF1alpha/TWIST/E-cadherin pathway may play an important role in the progression of OEC.

Clinicopathological significance of atypical glandular cells on Pap smear

OBJECTIVE: To investigate the clinical significance of atypical glandular cells (AGC) by analyzing the prevalence and histologic outcomes of patients with AGC according to Pap smear. METHODS: The medical records of 83 patients who were diagnosed AGC on Pap tests at the Pusan National University Hospital outpatient department and health care center from January 1998 to March 2006 were reviewed. RESULTS: The prevalence of AGC was 55 of 54,160 (0.10%) and 28 of 54,160 (0.05%) for AGC-not otherwise specified (NOS) and neoplastic associated AGC, respectively. The histopathologic results of the AGC-NOS group (n=55) were as follows: low-grade squamous intraepithelial lesion, 7 (12.7%); high-grade squamous intraepithelial lesion, 4 (7.2%); adenocarcinoma of cervix, 3 (5.4%); endometrial carcinoma, 2 (3.6%); and other malignancies including 2 ovarian cancer cases and 1 breast cancer case, 3 (5.4%). The histopathologic results for the AGC-associated neoplastic group (n=28) were as follows: low-grade squamous intraepithelial lesion, 1 (3.5%); high-grade squamous intraepithelial lesion, 3 (10.7%); adenocarcinoma of cervix, 5 (17.8%); endometrial carcinoma, 4 (4.8%); and additional malignancies including 3 stomach cancer cases, 2 ovarian cancer cases, and 2 breast cancer cases; 7 (25%). CONCLUSION: AGCs may represent a variety of benign and malignant lesions. AGC-associated neoplastic findings may be related to gynecological or extrauterine malignancies. Thus, when AGCs, especially neoplastic AGCs, are encountered, it is best to evaluate the cervix not only for typical maladies, but also for gynecological and non-gynecological malignancies.
