Introduction: Current protocols for staging gynaecological cancers include cytopathological examination of peritoneal washings taken at the time of definitive surgery. We investigated the clinical usefulness of this procedure.
Methods: During 2004 and 2005, 140 peritoneal washings were submitted for cytopathological examination in our institutions for staging of 36 ovarian, 101 endometrial and 3 synchronous ovarian/endometrial cancers.
Results: The washings contained malignant cells in 39 cases (28%). 35 of these cases had high stage disease – not confined to the organ of origin (i.e. stage 2 or more for ovary and stage 3 or more for endometrial). The other 4 were stage 1C ovarian cancers where there was either rupture or tumour involvement of the capsule. In only 2 of the 39 positive cases the cancer was marginally upstaged by the positive washings – these were ovarian cancers upstaged from 2A /B to 2C.
Discussion: These findings suggest that peritoneal washing cytology as a routine procedure for staging ovarian and endometrial cancer is of limited clinical value. A larger study is needed to determine whether this procedure should continue to be included in staging protocols for gynaecological cancer. 相似文献

OBJECTIVE: To evaluate histologic findings in patients aged 50 and older whose cervical smears revealed atypical glandular cells of undetermined significance (AGUS). STUDY DESIGN: Computerized records spanning a four-year period were retrospectively analyzed. Thirty patients over age 50 had cervical smears interpreted as AGUS and had follow-up biopsies within 12 months following the abnormal smear. The most important histologic diagnosis from the biopsy specimens was correlated with the subcategory of the cervical smear. RESULTS: Five smears interpreted as AGUS, favor reactive, revealed abnormal histology in four cases: three endometrial polyps and one squamous carcinoma. Two smears interpreted as AGUS, favor dysplasia, revealed squamous intraepithelial lesions on biopsy in both cases. Seventeen smears interpreted as AGUS, favor endometrial cells, revealed abnormal histology in 13 cases: 1 endocervical polyp, 6 endometrial polyps, 3 endometrial hyperplasias and 3 adenomyosis. Six patients with smears interpreted as AGUS, unclassifiable, revealed abnormal histology in five cases: two endocervical polyps, one endometrial polyp, one endometrial carcinoma and one ovarian carcinoma. CONCLUSION: The presence of AGUS in cervical smears from women over 50 was highly predictive of abnormal lesions detected by histologic examination. Although three cancers were detected on histologic follow-up, the most common lesions detected were endometrial polyps. 相似文献

Cervicovaginal and endometrial cytology in ovarian cancer 总被引:1,自引:0,他引:1
The clinical significance of cytologic examination was studied in 114 patients with ovarian cancer who had received preoperative cytologic examinations. The overall positive rate of the cytologic examinations was 26.3% (30 of 114): 22 (19.3%) of the 114 cases had positive cervicovaginal smears while 13 of 31 endometrial aspiration smears (41.9%) were positive. The positive rate was not related to the volume of ascites but rather to its presence or absence. Thus, if ascites was observed, the positive rate was about 2.1 times higher than if it was absent. In two of four cases of ovarian cancer with no endometrial invasion but a positive cytologic examination of ascitic fluid, fallopian tube specimens contained cancer cells; this suggests that ovarian cancer cells may reach the cervix and/or vagina by passing through the fallopian tube, particularly if ascites is present. Since cytologic examination, especially of endometrial aspiration smears, shows a high positive rate if ovarian cancer cells are observed in the abdominal cavity, cytology should be used as an important ancillary method for the assessment of ovarian cancer. 相似文献

The cytologic diagnosis of endometrial cancer using material obtained with the Endocyte endometrial sampler was assessed for 874 patients. The samples obtained were smeared directly on slides for fixation and staining; the smears were more difficult to assess than cervicovaginal smears, however, due to the presence of blood, the small size and density of the cells and the flattened three-dimensional architecture of the tissue fragments obtained. Only 8.2% of the samples were classified as inadequate; repeat sampling in some of those cases produced diagnostic material. All 12 cases of carcinoma (including one case in a woman less than 40 years of age) were diagnosed by cytology as malignant; however, the original cytologic sample in one of those cases was inadequate. For the diagnosis of benign versus malignant, cytology had a sensitivity of 92%, a specificity of 100% and predictive value of 100%. Cytology also diagnosed as suspicious the smears from 5 of 13 cases of endometrial hyperplasia and 2 of the 9 cases of endometrial polyps. The cytologic findings for benign and malignant samples are described and illustrated in detail. Relative to other endometrial sampling devices, the Endocyte is inexpensive and was easily used by the gynecologist and well tolerated by the patients, with no complications and minimal discomfort. 相似文献

OBJECTIVE: To evaluate the effect of tamoxifen on cervicovaginal epithelium and determine the value of cervicovaginal smears in identifying patients at risk for endometrial carcinoma. STUDY DESIGN: A group of 48 women with prior breast cancer were divided into three groups: A, tamoxifen-treated patients who developed endometrial carcinoma (n = 20); B, patients with endometrial cancer not treated with tamoxifen (n = 22); and C, tamoxifen-treated patients with no endometrial carcinoma (n = 16). A total of 114 cervicovaginal smears from these patients were evaluated for maturation index, histiocytes, benign and malignant endometrial cells, reactive cellular changes and microorganisms. All patients treated with tamoxifen had received doses of 10 mg twice daily. RESULTS: The maturation index was increased in tamoxifen-treated patients (A and C) versus nontreated patients (B) P < or = .001). The number of cases with endometrial cells was significantly higher in smears of treated patients who developed endometrial cancer (A) as compared to groups B and C (P = .01 and .02, respectively). Histiocytes were also significantly increased in the two groups that subsequently developed endometrial carcinoma (A and B) as compared to the group that did not (group C) (P = .02). There was no significant difference in the presence of reactive cellular changes between the three groups. CONCLUSION: Patients treated with tamoxifen exhibited a partial estrogenic effect in their smears regardless of whether they developed endometrial cancer. However, the presence of endometrial cells in the smears indicated a higher risk of endometrial adenocarcinoma. 相似文献

The accuracy of endometrial aspiration smears obtained with the Isaacs cell sampler in the diagnosis of malignant mixed mesodermal tumors (MMMT) was compared to the results obtained with routine cervical and vaginal smears in five cases of MMMT found in a series of 220 endometrial aspirations. Cervical and vaginal smears previously taken on these patients were positive for adenocarcinoma or MMMT in two cases and suspicious for adenocarcinoma in the remaining three cases. Endometrial aspirates were positive for MMMT in three cases and positive for adenocarcinoma or MMMT in two cases. The endometrial aspiration smears contained a variety of cells: malignant glandular, squamous, spindly stromal, undifferentiated, osteoid and tumor giant cells; chondrocytes and free psammoma bodies were also observed. These cases indicated that endometrial aspiration can accurately detect the heterologous cellular elements found in MMMT and is an effective technique in its diagnosis. 相似文献

OBJECTIVE: To determine the clinical implications of the finding of histiocytes in Pap smears in 1 patient population. STUDY DESIGN: The medical records and Pap smears which the presence of histiocytes was mentioned in the diagnosis between August 1996 and August 2001 were reviewed in conjunction with follow-up surgical findings. The positive predictive value (PPV) for significant endometrial pathology for the isolated finding of histiocytes on Pap smear was determined. RESULTS: Of the 238,225 women screened over a 60-month period, 325 were reported to have histiocytes in their Pap smears. Of them, 238 (73.2%) had subsequent endometrial sampling, hysterectomy or both, and follow-up Pap smears. Two hundred seven smears (87%) failed to disclose endometrial pathology. Thirty-one cases (13%) resulted in significant histopathologic findings, including 12 uterine malignancies, 8 endocervical polyps, 7 endometrial polyps, 2 submucosal leiomyomata, 1 simple hyperplasia without atypia and 1 case of tamoxifen-related changes. Upon review of the clinical records, 58% (18/31) of those patients had other significant clinical and/or cytologic findings. Five of the 18 patients (27.8%) had associated postmenopausal bleeding, 11 had additional abnormal Pap smear findings (atypical glandular cells, 6/18, or 33.3%; endometrial cells, 5/18, or 27.8%), and another 2 had both postmenopausal bleeding and atypical glandular cells (2/18, or 11.1%). The PPV for significant uterine pathology for women with the isolated finding of histiocytes on a Pap smear was 5.5% and 60% with additional clinical and/or Pap smear findings. The PPV for endometrial cancer was 1.3% in women with the isolated finding of histiocytes on a Pap smear but 20% for women with histiocytes and additional clinical/or Pap smear findings. CONCLUSION: Based on the findings of this study and recently published data, we conclude that the isolated finding of increased histiocytes in the absence of postmenopausal bleeding, endometrial cells or atypical glandular cells on a Pap smear is a poor indicator of uterine disease. 相似文献

OBJECTIVE: To evaluate the usefulness of endometrial aspiration cytology for assessing malignant cells of extrauterine origin. STUDY DESIGN: Endometrial cytology was performed on 224 patients with primary ovarian cancer, 10 with fallopian tube cancer and 45 with peritoneal tumors. RESULTS: Of 224 patients with ovarian cancer, 53 (23.7%) had positive endometrial cytology. Positive rates were: stage I, 4.3%; stage II, 25.0%; stage III, 39.7%; stage IV, 34.5%. Histologic positive rates were: serous, 28.7%; mucinous, 11.4%; clear cell, 23.1%; endometrioid and unclassifiable adenocarcinomas, 28.0%. Of 5 patients with ovarian cancer, 2 were asymptomatic, but aspiration cytology was positive. Of 10 patients with fallopian tube cancer, 9 (90.0%) had positive endometrial cytology. The positive rate on endometrial cytology was 56.7% in stomach cancer, 60.0% in breast cancer and 20.0% in colon cancer. Of 1,209 women with stomach cancer, 30 (2.4%) displayed ovarian metastasis. Of these, 7 (23.3%) had Krukenberg's tumor; endometrial cytology was positive in 1 (14.3%). In 7 of 17 patients with positive endometrial cytology, clinical diagnosis was made before stomach cancer therapy. CONCLUSION: Endometrial aspiration cytology is useful for identifying nongynecologic malignant cells, diagnosing ovarian and fallopian tube cancers, and determining peritoneal dissemination and metastasis originating from gastrointestinal and breast cancers. 相似文献

OBJECTIVE: To determine the significance of pregnancy-related cells in endometrial smears. STUDY DESIGN: Pregnancy-related cells in 4429 endometrial smear samples were retrospectively analyzed and evaluated for clinicopathologic and cytomorphologic features. RESULTS: Of the 4429 endometrial smears taken for cancer screening, pregnancy-related cells were detected in 12 cases (0.3%). They were estimated cytologically as negative or suspicious and confirmed as cases ofspontaneous abortion (8 cases), placental site nodule (3 cases), and partial hydatidiform mole (1 case). Decidual cells were observed in all cases, and some of these showed atypia. Trophoblasts were observed in 5 (41.7%) of the 12 cases. Syncytiotrophoblasts were observed in 1 case (8.3%) and nonsyncytiotrophoblasts in 5 (41.7%) of the 12 cases. Pregnancy-related cells were observed in an endometrial smear in 7 cases; other cases were missed during cytologic examination and were retrospectively identified. CONCLUSION: Pregnancy-related cells are likely to be missed because they are difficult to identify or are surrounded by a cluster of endometrial cells. The decidual cell is a key cell for the cytologic diagnosis of pregnancy-related cells. Determining the existence of pregnancy-related cells in endometrial smears is important for the further assessment of patients and the differential diagnosis of several endometrial lesions. 相似文献

OBJECTIVE: To evaluate incidence, cytology findings and pathology outcome of atypical glandular cells (AGC) in Pap smears according to the 2001 Bethesda criteria. STUDY DESIGN: From 103,073 consecutive Pap smears, 113 (0.1%) AGC cases were identified. Of these, 91 (80%) had adequate histologic evaluation included in this study. RESULTS: Abnormal histology findings were seen in 38 patients (42%). Final pathology results revealed 14 endometrial adenocarcinomas, 5 endocervical adenocarcinomas, 1 cervical squamous cell carcinoma, 1 endometrial stromal sarcoma, 6 other malignancies, 4 endocervical adenocarcinomas in situ, 4 cases ofendometrial complex byperplasia, 1 case of endocervical glandular dysplasia and 2 cases of cervical intraepithelial neoplasia 3 with glandular involvement. Women with AGC, favor neoplasia, were more likely to have significant pathology than those with AGC, not otherwise specified, 74% vs. 33% (p = 0.002). Some characteristic background cytologic findings were also noticed in most cases of endometrial, fallopian tube and endocervical adenocarcinoma. CONCLUSION: A diagnosis of AGC is more clinically significant by the 2001 Bethesda System, especially the "AGC, favor neoplastic" category. Some background cytologic features are important because they are indicators of malignancy. 相似文献

OBJECTIVE: To retrospectively review, based on cytologic and histopathologic findings, the diagnoses of 13 patients with uterine sarcoma and 1 with vaginal sarcoma. STUDY DESIGN: There were 8 cases of uterine carcinosarcoma (CS), 2 of leiomyosarcoma, 2 of endometrial stromal sarcoma (ESS), 1 of endocervical stromal sarcoma (ECSS) and 1 of malignant fibrous histiocytoma (MFH) of the vagina. The presence of sarcomatous components was retrospectively investigated by microscopic observation of preoperative specimens from the endocervical canal and endometrial cells. Characteristic features of sarcomatous cells were then investigated by cytodiagnostic micrometry of malignant cells. RESULTS: Of the 14 patients, 1 with low grade ESS and 1 with homologous CS were diagnosed as negative for sarcomatous components. One case of high grade ESS had been overlooked, as were 4 cases of CS. Thus, 7 cases (50%) were diagnosed as positive for sarcomatous cells by preoperative cytologic observation. Based on these findings, 12 of the 14 cases (85.7%) were positive for sarcomatous elements on retrospective reexamination of the specimens. CONCLUSION: Careful attention should be paid to small sarcomatous cells since cases of ESS or ECSS with such cells show morphologic characteristics similar to those of stromatous cells. Furthermore, careful microscopic observation of an entire specimen is required to avoid misdiagnosis as carcinoma since it is easy to overlook sarcomatous elements in smears with carcinosarcoma if there are only a few sarcomatous cells. 相似文献

To determine whether the cytohormonal status of postmenopausal women with cancer involving the uterus and vagina differs from that of women free of cancer, 100 women 60 years of age or older with positive cervicovaginal smears were compared with an age-matched control group without malignant neoplasms. Epidermoid carcinoma was identified in 64 patients (average age: 67 years) and adenocarcinoma in 34 patients (average age: 69 years). One patient had leiomyosarcoma, and another had bladder carcinoma. The paucity of benign squamous cells in the smears precluded hormonal evaluation in 32% of the index cases; the smears from 10% of the controls were also indeterminate. Of the evaluable cases with epidermoid carcinoma of the cervix, a high maturation was noted in 46% as compared to 11% for the matched controls. In addition, high maturation was noted in 69% of those patients with endometrial adenocarcinoma as compared to 19% for the matched controls. None of the index cases were atrophic; 31% of the controls were. A history of exogenous estrogen usage was obtained in three patients with endometrial adenocarcinoma, all with high maturation, and in five controls, none with high maturation. These data appear to indicate a difference in the cytohormonal status of patients with cervical or endometrial carcinoma as compared to those without; consequently, cytologists should be especially attentive to smears showing high maturation from postmenopausal women. 相似文献

Reports from sequential series of 234,318 cervicovaginal smears from a period of three years were reviewed to ascertain the prevalence and significance of psammoma bodies. Seven smears contained psammoma bodies. Three of the seven were associated with benign conditions and four were associated with a cancer (two serous papillary endometrial adenocarcinomas, one ovarian serous cystadenocarcinoma and one serous papillary carcinoma of the peritoneum). The prevalence of psammoma bodies in benign cases was much higher than reported in previous studies, in which most findings of psammoma bodies were associated with malignancy, particularly ovarian carcinoma. A consistent and useful feature in distinguishing psammoma bodies associated with benign or malignant disease was the presence of a few adherent small bland-appearing glandular cells in benign disorders and adherent malignant glandular cells in cases of carcinoma. A more conservative work-up may be merited in young women with clearly benign cells associated with psamoma bodies in a cervicovaginal smear and an otherwise negative physical examination and noncontributory endometrial sampling. 相似文献

OBJECTIVE: To evaluate cytologic criteria for separating atypical glandular cells of undetermined significance favor endometrial origin (AGUS-EM), on Papanicolaou-stained (Pap) smears into favor benign and favor malignant categories. STUDY DESIGN: All patients who had a Pap smear diagnosis of AGUS-EM, not further qualified, followed by tissue follow-up were identified from the surgical pathology and cytopathology files from January 1992 through December 1996. The Pap smears were scored blindly for the presence or absence of 40 cytologic criteria, and univariate analysis was performed to determine which criteria were most indicative of malignancy by tissue follow-up. RESULTS: The presence of an atrophic smear, nuclear size greater than twice that of an intermediate cell nucleus and absence of clusters with irregular borders were highly indicative of adenocarcinoma, although other criteria were also helpful in identifying malignancy. CONCLUSION: There are no combinations of cytologic criteria that definitely separate AGUS-EM cases into those with benign or malignant findings on follow-up. However, some isolated criteria were useful in the differential diagnosis in a [table: see text] significant number of cases. 相似文献

OBJECTIVE: To determine the significance of cytologically normal endometrial cells in cervicovaginal (CV) smears from postmenopausal women over age 55 years. STUDY DESIGN: From January 1995 to January 1998, 220 women had CV smears demonstrating cytologically normal endometrial cells. The menopausal status, hormone replacement therapy (HRT) and information related to subsequent CV smears and endometrial sampling within 12 months of the initial diagnosis was recorded. RESULTS: Eighty-one of the 220 cases (36.8%) had histologic sampling of the endometrium. Thirty-four of 81 (42%) showed no endometrial pathology. Endometrial pathology was identified in 28 of 81 (34%), of which 19 were endometrial polyps (23.4%), 4 were endometrial hyperplasia (4.9%), 4 were endometrial carcinoma (4.9%) and 1 was a leiomyoma (1.2%). Nineteen (23.4%) were insufficient for diagnosis. Ninety-one of 220 women were on HRT, and 129 were not. In the group without HRT, endometrial disease was identified in 22/51 (43%) cases as compared to 6/30 (20%) in the group with HRT (P < .001). Endometrial carcinoma was identified in three (5.8%) cases and one (3.3%) case without and with HRT, respectively. CONCLUSION: Although the finding of normal endometrial cells in Pap smears from postmenopausal women was without any clinical significance in the majority of women in this study, in a small number it was associated with endometrial hyperplasia and carcinoma. Women who were not on HRT had a higher incidence of endometrial pathology. 相似文献

The influence of postsurgical stage, histologic grade and cytologic grade of the tumor on the rate of detection of endometrial carcinoma by cervical smear was examined in a retrospective study. Cervical smears from 220 patients with endometrial carcinoma seen in the years between 1965 and 1981 were reevaluated for the presence of normal, suspicious or frankly malignant endometrial cells. The smears were positive in 33.2% of the patients, suspicious in 25.5% and negative in 40%. In three cases (1.4%), the smear was technically inadequate. Positive or suspicious smears indicated the presence of a higher grade as well as a higher stage of the lesion. In this material, the presence of normal endometrial cells as an indicator of endometrial disease, as emphasized in the literature, proved useless since normal endometrial cells without accompanying malignant cells were not seen in a single case. It appears that the reason for the lower rate of detection of low-grade endometrial carcinoma is the complete absence of any exfoliation in these lesions. 相似文献

Introduction: To establish the significance of cytological features which could predict clinically significant endometrial pathology, and therefore guide reporting practice in cervical samples.
Methods: A retrospective review of SurePath liquid-based cytology (LBC) cervical samples between 2002 and 2006, obtained at screening and colposcopy. These smears contained normal endometrial cells present at inappropriate times of the menstrual cycle, endometrial cells with atypia (borderline change) and with features suspicious / diagnostic of endometrial carcinoma (glandular neoplasia). False negative and false positive cases detected on subsequent histology were also included. The control group comprised negative samples and a few abnormal smears. All smears were randomly assigned and blinded to menopausal status, age, use of oral contraceptive pill and hormone replacement therapy and presence of intrauterine device. Each smear was reviewed for 16 cytologic criteria and a cytological diagnosis was given for each.
Results: A total of 219 smears were available for review; 137 were negative, out of which 85 contained normal endometrial cells, 41 contained endometrial cells with atypia, 10 contained endometrial cells with features suggestive of adenocarcinoma and 31 contained endometrial cells with features diagnostic of adenocarcinoma. The feature most associated with benign endometrial cells is top hat with central cell condensation. In contrast, the features associated with malignant endometrial cells are smooth nuclear membrane, pale chromatin, small nucleoli and scalloped borders.
Discussion: The criteria identified in this study do not definitively define a neoplastic process, but appear to be helpful in individual cases. This study emphasises that endometrial changes should be always interpreted with the relevant clinical information, which would otherwise lead to overdiagnosis in premenopausal women. 相似文献

OBJECTIVE: To evaluate the significance of histiocytes on normal cervical smears from postmenopausal women and correlate them with endometrial pathology. STUDY DESIGN: Histiocytes were classified into three types. The clinical history was obtained from cytologic and surgical reports. RESULTS: Among 108 cervical smears, 13 had large, foamy histiocytes (type A), 88 had histiocytes resembling superficial endometrial stromal cells (type B), and 7 had variably sized histiocytes alone or in association with inflammatory or multinucleated cells (type C). Endometrial pathology was identified in 13 patients (12.0%): 4/13 with type A histiocytes (2 endometrial adenocarcinomas, 2 endometrial polyps), 8/88 with type B histiocytes (8 endometrial polyps) and 1/7 with type C histiocytes (endometrial polyp). Among 70 patients with no clinical indications for endometrial sampling except for the presence of histiocytes, 4 demonstrated endometrial pathology (all endometrial polyps). In contrast, endometrial pathology was identified in 9/38 with clinical indications for endometrial sampling. Among the 13 patients with endometrial pathology, 9 had a significant clinical history (sensitivity of 69.2%), and 4 had histiocytes as the only indication for endometrial biopsy (sensitivity of 30.8%). CONCLUSION: A significant clinical history is more predictive of endometrial pathology and outweighs the significance of histiocytes as an indication for endometrial biopsy. 相似文献

OBJECTIVE: To assess the relationship of a cervical cytologic diagnosis based on number, size and degeneration of malignant clusters and necrotic background to cervical involvement of endometrial carcinoma. STUDY DESIGN: Cervical smears of 53 women with endometrial carcinoma were evaluated for cervical involvement. The cytologic diagnosis was compared with actual involvement, and accuracy was calculated. Retrospectively, cytologic features, including number, size and degeneration of malignant clusters and necrotic background, were analyzed in involved and noninvolved cases. RESULTS: Cervical involvement was confirmed in 15 patients (28.3%). The number and size of malignant clusters in the involved cases were significantly larger than those in the noninvolved cases (P < .001 and < .01, respectively). The proportion of degenerated malignant cells and necrotic background in involved cases were significantly higher than those in noninvolved cases (P < .05). Cytologic diagnosis had a sensitivity and specificity of 62.5% and 86.8%, respectively. CONCLUSION: Cervical smears of involved cases revealed a large number and large size of malignant clusters. These findings support cytologic diagnosis based on number, size and degeneration of malignant cells and necrotic background. Cervical cytology is useful to exclude cervical involvement because of its high specificity and can help detect cervical involvement because of its moderately high sensitivity. 相似文献

Signet ring cell lobular carcinoma of the breast presenting in a cervicovaginal smear. A case report
BACKGROUND: The presence of extragenital malignant cells in cervicovaginal smears is a rare and usually late event in a patient with a long history of cancer. This, to the best of our knowledge, is the first case of breast cancer initially diagnosed on a Pap smear. CASE: A 50-year-old woman presented with abdominal distension and weight gain. A Pap smear showed numerous signet ring cells and was diagnosed as signet ring cell adenocarcinoma, most likely metastatic from the breast or stomach. Subsequent evaluation revealed bilateral adnexal masses and inguinal lymphadenopathy, leading to hysterectomy and bilateral salpingo-oophorectomy. The ovaries, corpus and cervix were involved by signet ring cell carcinoma. The metastatic tumor proved to be positive for CK7, CEA, estrogen receptor and progesterone receptors and negative for CK20. Despite the absence of a discrete palpable breast mass, a mammogram was recommended based on these results, and an ensuing breast biopsy showed the presence of an infiltrating lobular carcinoma. CONCLUSION: Lobular carcinoma of the breast may present in a cervicovaginal smear. Correct interpretation of signet ring cells as metastatic, most likely from the breast or stomach, is helpful in guiding management. 相似文献
