Clinico-cytological study of uterine papillary serous carcinoma

OBJECTIVE: The aim of this study was to determine whether or not we could distinguish uterine papillary serous carcinoma (UPSC) from other types of endometrial cancer by cytology. METHODS: We examined the cytological findings of the endometrium from five cases with UPSC and compared them with 10 cases with endometrioid adenocarcinoma, grade 1 (G1). A morphometric analysis was performed. Cytological samples from the cervix and ascites of the patients with UPSC were also reviewed. RESULTS: All five patients had FIGO stage III and IV tumours. Three patients died of the disease and two are still alive with disease. The tumour cells of UPSC tended to be shed in papillary clusters with a tumour diathesis. Psammoma bodies were seen only in UPSC. The frequency of irregular-shaped nuclei, membrane thickness and eccentric nuclei in UPSC was higher than in G1. The chromatin pattern was coarsely granular, and both anisonucleosis and bare nuclei were prominent in UPSC. Cytomorphometrically, the maximum diameter of the nuclei in UPSC was significantly greater than that in G1. The nucleoli were also more often seen in UPSC than in G1. The findings of the nuclei and nucleoli in the cervical and peritoneal fluid cytology closely resembled those in endometrial smears. The features of the cervical smears and peritoneal fluid cytology were different from those of endometrial cytology regarding clear background and small clusters of cells. CONCLUSION: As the endometrial cytology findings accurately suggested the histological diagnosis of UPSC, the diagnosis of UPSC was confirmed in this study by endometrial cytology. The cytological diagnosis of UPSC should be based on the findings of tumour diathesis, psammoma bodies and papillary clusters composed of tumour cells with enlarged nuclei and numerous nucleoli.     

Diagnosing endometrial carcinoma with cervical involvement by cervical cytology

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.     

The detection of endocervical gland involvement by high grade squamous intraepithelial lesions in smears prepared from endocervical brush specimens

The cytologic features of squamous cell carcinoma in situ with endocervical gland involvement have been described in cervical smears. We evaluated the presence of two types of cellular fragments in 43 cervical smears of high grade squamous intraepithelial lesions (HGSIL) to assess their ability to predict glandular involvement by HGSIL in subsequent cone biopsies. an endocervical brush was used to obtain all endocervical specimens. of 16 cases without glandular involvement, fragments were present in 13 smears. of 27 cases with glandular involvement, fragments were absent in 11 smears. No statistical association was identified between the presence of abnormal cellular fragments on cervical smears of HGSIL and endocervical gland involvement on cone biopsies.     

Cytologic features of endometrial papillary serous carcinoma

Endometrial papillary serous carcinoma (EPSC) is an uncommon variant of endometrial carcinoma that histologically resembles ovarian serous carcinoma and has an aggressive clinical course. The cytomorphologic features of 17 patients with histologically confirmed EPSC of the endometrium were reviewed and compared with those of 20 patients with histologically typical endometrial adenocarcinoma (TEC). Preoperative cervicovaginal Papanicolaou smear results were available from 14 of the 17 patients with EPSC; 10 (71%) were positive, 1 (7%) was suspicious and 3 (21%) were negative for malignancy. Initial cervicovaginal smear results were available from all 20 patients with TEC; 7 (35%) were positive, 4 (20%) were atypical or suspicious and 9 (45%) were negative for malignancy. Twelve patients with EPSC had peritoneal washings or fluids examined; seven were positive and five negative. Twelve patients with TEC had peritoneal washings or fluids examined; two (17%) were positive and ten (83%) were negative. The cervicovaginal smears from patients with EPSC revealed numerous large tumor cells (with prominent nucleoli) frequently arranged in papillary clusters with background necrosis and, in two cases, amorphous material suggestive of psammoma bodies. In contrast, the smears of patients with TEC showed small to medium-sized cells with extensive phagocytosis and many background histiocytes. The diagnosis of EPSC should be considered when the cervicovaginal smear contains numerous papillary groups of large tumor cells with macronucleoli but without prominent phagocytosis, especially when structures suggestive of psammoma bodies are present. The peritoneal fluids in these patients are more often positive than in patients with TEC, a finding consistent with the propensity of EPSC to involve peritoneal surfaces.     

Contribution of cervical cytology in the diagnostic work‐up of patients with endometrial cancer

Introduction

Abnormal cervical cytology in patients with endometrial cancer (EC) has been associated with poor outcome. The aim of this study was to evaluate whether cervical cytology could contribute to an improved preoperative identification of high‐grade EC (serous, clear cell, carcinosarcoma, high‐grade endometrioid EC) in final histology.

Methods

A retrospective cohort study was performed in five hospitals in the Netherlands. A total of 554 patients with EC that underwent primary surgical treatment between 2002 and 2010 were included. Primary outcome was defined as the contribution of abnormal cervical cytology in the preoperative identification of high‐grade EC. As secondary outcome, recurrence‐free survival (RFS) and disease‐specific survival were determined based on preoperative cervical cytology, and compared to the currently established risk factors: myometrial invasion, high‐grade and lymph vascular space invasion.

Results

Abnormal cervical cytology was present in 45.1%. For patients with preoperative inconclusive and high‐grade histology, the presence of abnormal cervical cytology contributed to an improved identification of high‐grade EC in final histology (odds ratio [OR] 6.40 [95% confidence interval {CI}: 1.92‐21.26]; OR 2.86 [95% CI: 1.14‐7.14]), respectively. Patients with abnormal cervical cytology had a significant worse 5‐year median RFS. Abnormal cervical cytology was independently related to RFS (hazard ratio 1.67 [95% CI: 1.04‐2.68]) and disease‐specific survival (hazard ratio 3.15 [95% CI: 1.74‐5.71]).

Conclusions

Abnormal cytology contributes to the preoperative identification of patients with high‐grade EC, and is associated with compromised outcome. Future studies are warranted to determine whether cervical cytology could be incorporated into preoperative prediction models for lymph node metastasis.     

A study to determine the underlying reason for abnormal glandular cytology and the formulation of a management protocol

A retrospective review is presented of 89 patients with glandular dyskaryosis in order to formulate a management protocol. Fifteen patients had cervical intraepithelial neoplasia (CIN) without glandular abnormality (17%). One patient had adenocarcinoma in situ of the cervix and one patient had vaginal intraepithelial neoplasia (VAIN) grade III. Twenty‐two patients had endometrial carcinoma (24.5%) and 11 patients had cervical carcinoma (12.5%). Of the patients presenting with post‐menopausal bleeding as well as having glandular dyskaryosis, 69% had a gynaecological malignancy. In conclusion, colposcopy and out‐patient endometrial sampling are recommended in all cases. Patients with abnormal endometrial sampling require hysteroscopy. Cone biopsy is necessary to exclude occult glandular disease if cytology remains abnormal despite negative colposcopy and sampling.     

Clinicopathologic relevance of asymptomatic endometrial carcinoma

OBJECTIVE: To assess whether screening asymptomatic women is significant for early detection of endometrial carcinoma. STUDY DESIGN: We compared the clinicopathologic findings and prognoses of 21 asymptomatic patients with 427 symptomatic patients with endometrial carcinoma. RESULTS: The incidence of asymptomatic endometrial carcinoma was 4.7%. Nineteen of 21 asymptomatic patients with endometrial carcinoma were found by cytologic screening for endometrial cancer. There was a statistical difference in the histopathology and depth of myometrial invasion between the asymptomatic and symptomatic groups. However, no statistical differences were found in tumor grade, lymph node metastasis, adnexal metastasis, cervical invasion, peritoneal cytology, surgical stage and patient age. Univariate analysis showed that the presence or absence of symptoms was not related to survival. CONCLUSION: The detection of asymptomatic endometrial carcinoma is not related to a reduced mortality rate. Screening asymptomatic women for endometrial carcinoma is not recommended.     

Micropapillary variant of transitional cell carcinoma of the urinary bladder: a report of three cases with cytologic diagnosis in urine specimens

BACKGROUND: Micropapillary transitional cell carcinoma is a recently described, aggressive variant of bladder cancer. Its cytologic features in urine have not been previously characterized. CASES: Three cases illustrate the urinary cytologic features of this high grade urothelial carcinoma and its concurrent biopsy findings. This tumor is similar to low. grade urothelial lesions of the bladder, tends to present as micropapillary clusters in urine and yet has high grade nuclear features within these clusters that help with the differential diagnosis of a flat, high grade urothelial carcinoma. CONCLUSION: The micropapillary type of transitional cell carcinoma is a distinct morphologic entity with an aggressive clinical course. Recognizing its presence in urinary cytology, albeit a rare occurrence, is important in distinguishing this lesion from the more indolent, low grade papillary lesions and high grade urothelial carcinomas, which continuously shed single malignant urothelial cells.     

Utility of liquid-based cytology in endometrial pathology: diagnosis of endometrial carcinoma

Objective: The purpose of this study was to examine the utility of SurePath‐liquid‐based cytology (LBC) compared to conventional cytological preparations (CCP) in the identification of endometrial carcinoma. Methods: During a 13‐month period, direct endometrial samples were collected from 120 patients using the Uterobrush. The material comprised 30 cases each of endometrial carcinoma, proliferative endometrium, secretory endometrium and atrophic endometrium. The following points were investigated:(i) the frequency of cell clumps in endometrial carcinoma; (ii) the area of cell nuclei; (iii) overlapping nuclei. Results: (i) Comparison of the frequency of cell clumps with irregular protrusion pattern and papillo‐tubular pattern showed no statistically significant difference in either type of cell clump between CCP and LBC. (ii) Comparison of the nuclear area of cells showed a sequential decrease from endometrial carcinoma to secretory endometrium, to proliferative endometrium and to atrophic endometrium, which was significant in CCP and LBC. (iii) Nuclear area was significantly lower with LBC compared with CCP in endometrial carcinoma, secretory endometrium and proliferative endometrium but not atrophic endometrium. (iv) Comparison of the degree of overlapping nuclei showed a sequential decrease from endometrial carcinoma to proliferative endometrium, to secretory endometrium and to atrophic endometrium, which was significant in both CCP and LBC. (v) Comparison of the degree of overlapping nuclei between CCP and LBC showed no significant difference for normal types of endometrium, but LBC had significantly higher values (P < 0.0001) in endometrial carcinoma than in CCP. Conclusions: The results of this study revealed that applying diagnostic criteria used in CCP to LBC was easy to achieve, because LBC had excellent cytoarchitectural preservation and cells were well presented. Although we have not examined all cytological features of malignancy and have not considered atypical hyperplasia, we believe that this method may be a useful tool in the diagnosis of endometrial cytology.

Diagnostic accuracy of liquid‐based endometrial cytology cytology in the evaluation of endometrial pathology in postmenopausal women Objective: The aim of this study was to compare liquid‐based endometrial cytology with hysteroscopy and endometrial biopsy regarding its diagnostic accuracy in a series of postmenopausal women with abnormal uterine bleeding (AUB) or asymptomatic women with thickened endometrium assessed by transvaginal ultrasound as a screening procedure. Methods: Inclusion criteria were: menopausal status; the presence of AUB and/or thickened endometrium assessed by ultrasound (cut‐off 4 mm); a normal Papanicolaou (Pap) smear; and no adnexal pathology at ultrasound. Exclusion criteria were: previous endometrial pathology; and previous operative hysteroscopy. Of 768 postmenopausal women referred to our general gynaecology clinics, 121 fulfilled the inclusion criteria and were recruited to the trial. Twenty‐one refused to participate. Cytological sampling was carried out by brushing the uterine cavity using the Endoflower device with no cervical dilation and the vial was processed using a ThinPrep® 2000 automated slide processor. The slides were stained using a Pap method. Results: In 98 cases with histological biopsies, endometrial cytology detected five cases of endometrial carcinoma, 10 of atypical hyperplasia and 47 of non‐atypical hyperplasia; 36 cases were negative. In two cases cytology was inadequate because of uterine cervical stenosis. Taking atypical hyperplasia or worse as a positive test and outcome, the diagnostic accuracy of the endometrial cytology was 93.5%, with a sensitivity of 92% and specificity of 95%, a positive predictive value of 73% and a negative predictive value of 99%. All the carcinomas were detected by cytology. Only 42% of women with a positive diagnosis were symptomatic. The cytological sampling was well tolerated by all patients. No complication was registered. Conclusions: Liquid‐based endometrial cytology can be considered an useful diagnostic method in the detection of endometrial pathology as a first‐line approach, particularly if associated with transvaginal ultrasound.     

Problems in cervicovaginal cytology: fine structure as an aid to diagnosis

The ultrastructure of cytologically abnormal, thick cell groups and epithelial fragments in cervical and vaginal scrape material was investigated and found to be useful in differentiating between carcinoma in situ, invasive nonkeratinizing squamous carcinoma and adenocarcinoma of the endocervix and also in confirming the presence of cytologically suspected vault deposits of recurrent endometrial adenocarcinoma. It was demonstrated that although accurate evaluation of these thick groups in smear preparations is often not possible, thick sections of similar, plastic-embedded material showed some features which enabled a distinction to be made between squamous and glandular lesions and that these differences were more pronounced at the ultrastructural level. The squamous lesions were characterized by wide intercellular spaces with microvilli and tonofibrils within the cytoplasm while glandular lesions showed narrow intercellular spaces, prominent Golgi zones and endoplasmic reticulum together with mucus droplets in some cells.     

Factors determining the degree of endometrial exfoliation and their diagnostic implications in endometrial adenocarcinoma

Since the degree of endometrial exfoliation largely determines the ability of cytology to diagnose endometrial adenocarcinomas by the study of cervicovaginal smears, five features of their subsequent histologically diagnosed endometrial adenocarcinomas were studied in 28 patients whose smears contained endometrial cells. The surface area occupied by abnormal endometrium was found to be an important determinant in the degree of endometrial exfoliation. The tumor grade, endocervical involvement, pattern of growth and squamous-cell component were all factors that influenced cellular shedding. The extent of myometrial involvement did not affect the likelihood that an endometrial adenocarcinoma would be diagnosed cytologically prior to histologic examination.     

Split-sample analysis of discarded cells from liquid-based Pap smear sampling devices

OBJECTIVE: To examine cells that were retained on sampling devices used to collect ThinPrep (Cytyc Corp., Boxborough, Massachusetts, U.S.A) Pap smears in order to evaluate both the number and significance of cells that are routinely discarded with these devices after liquid-based specimens are collected. STUDY DESIGN: One hundred Pap smears from 100 women were prospectively procured after gynecologic Pap smears were collected for the ThinPrep Pap test. The sampling end of the collection devices was cut off and placed in a vial that contained SUREPATH preservative fluid (TriPath Imaging, Inc., Burlington, North Carolina, U.S.A). The residual cell samples were processed using the SurePath PREPSTAIN slide processor (TriPath). A single liquid-based slide was prepared from the sampling devices from each of the 100 specimens collected. The slides produced from the discarded devices were reviewed for the following: squamous cells, endocervical component, epithelial cell abnormalities and miscellaneous findings. The slides prepared from the "throw-away" (TA) material were subsequently compared with the primary ThinPrep Pap smear slide. RESULTS: Twenty-five percent of the TA samples had an equal or greater number of squamous cells per high-power microscopic field when compared to the primary ThinPrep slide, with 8% of the TA slides demonstrating greater overall cellularity. An endocervical component was present on 27 of 66 cervical samples (40.9%). Three of five cases (60%) interpreted as atypical squamous cells of undetermined significance had similar cells on the TA slides. Two cases of atypical glandular cells of undetermined significance had no abnormal cells on the TA slides. Twelve of 14 cases (85.71%) of low grade squamous intraepithelial lesion contained similar cells on the TA slides. Two of four cases (50%) of high grade squamous intraepithelial lesion also had similar abnormal cells on the TA slides. Miscellaneous findings included 1 case of benign endometrial cells and 4 Candida infections present on both preparations, along with 1 case of Trichomonas vaginalis organisms present on the ThinPrep slide only. In 1 specimen, several multinucleated histiocytic giant cells were present only on the TA slide. CONCLUSIONS: Specimens prepared from TA collecting devices used for the ThinPrep Pap test are less sensitive than the primary specimen for the detection of cervical lesions. This is in contrast to split-sample studies involving ThinPrep and conventional smears. Our study documented the presence of normal and abnormal cells discarded from ThinPrep sampling devices in a high percentage of cases. Discarded abnormal cells on the TA slides were, however, few when compared to the primary specimen, with only 1 exception involving a high grade lesion.     

Peritoneal washings in endometrial carcinoma. A study of 298 patients with histopathologic correlation

OBJECTIVE: To correlate findings of peritoneal washings in patients with endometrial carcinoma with histologic parameters. STUDY DESIGN: Between 1995 and 1998, 298 women with endometrial carcinoma were treated by hysterectomy with intraoperative peritoneal washings (PW) at Memorial Sloan-Kettering Cancer Center. All cytology and pathology slides were available for review. Pathologic parameters of hysterectomy specimens were evaluated and correlated with the findings of PW. RESULTS: Thirty-two patients (10.7%) had abnormal PW. Two hundred sixty-two had endometrioid adenocarcinoma; 26 of them had abnormal PW (10.0%). Thirty-six patients had other histologic subtypes (papillary serous carcinoma, clear cell carcinoma and adenosquamous carcinoma), and six of them had abnormal PW (16.7%). The incidence of abnormal PW in the two groups was not significantly different (P = .78). Among 26 patients with endometrioid adenocarcinoma and abnormal PW, there were 17 cases (9.9%) of International Federation of Gynecology and Obstetrics (FIGO) grade 1, 7 (12.7%) of grade 2 and 2 (5.7%) of grade 3 (P = .56). Ten cases (14.9%) had no myometrial invasion, 10 (7.0%) had myometrial invasion of < or = 50% of myometrial thickness, and 6 (11.5%) had invasion of > 50% of myometrial thickness (P = .18). Vascular invasion was present in 8 cases (14.8%) and absent from 17 (8.2%) (P = .14). Eighteen patients (7.6%) had stage I/II disease, and eight patients (30.8%) had stage III/IV disease (P = .001). Among 298 patients, cervicovaginal smears performed before surgery were available for review in 76. Five of the 7 patients (71.4%) with abnormal PW and 37 of the 69 patients (53.6%) with normal PW had abnormal Pap smears (P = .45). CONCLUSION: Abnormal PW did not correlate with histologic subtypes, FIGO grade, depth of myometrial invasion, vascular invasion or abnormal Pap smears. A significantly higher incidence of abnormal PW was associated with stage III/IV disease.     

Cytohistologic correlation between AGUS and biopsy-detected lesions in postmenopausal women

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.     

Pap smears in women with endometrial carcinoma

OBJECTIVE: To correlate Pap smear findings with the histology of endometrial carcinoma and stage of the disease. STUDY DESIGN: Between 1995 and 1998, 76 women with endometrial carcinoma, having had Pap smears done within two to three months of hysterectomy at Memorial Sloan-Kettering Cancer Center, formed the basis for this study. All Pap smears and histologic sections were reviewed. RESULTS: Thirty-four patients had normal Pap smears (45%), and 42 had abnormal ones (55%). The mean age of the two groups was 65.1 and 65.2 years, respectively. Histologic subtypes included 44 International Federation of Gynecology and Obstetrics (FIGO) grade 1 endometrioid adenocarcinoma (low grade) and 32 high grade carcinomas, including 19 FIGO grade 2 or 3 endometrioid adenocarcinomas, 5 papillary serous carcinomas (PSC), 2 clear cell carcinomas (CC), 1 adenosquamous carcinoma, 3 endometrioid adenocarcinomas mixed with PSC and 2 endometrioid adenocarcinomas mixed with CC. The proportions of patients with low and high grade tumors with abnormal Pap smears were 43% (19/44) and 72% (23/32), respectively (P=.01). The proportions of patients with abnormal Pap smears and no myometrial invasion, invasion of <50% and >50% myometrial thickness were 40% (8/20), 62% (26/42) and 57% (8/14), respectively (P =.27). Vascular invasion was identified in 56% (9/16) of patients with abnormal Pap smears and in 55% (33/60) of patients with normal ones (P = .93). The proportions of patients having abnormal Pap smears with stage I and stages II, III or IV disease were 48% (30/62) and 86% (12/14), respectively (P =.01). CONCLUSION: Although the Pap smear is not a sensitive screening test for endometrial cancer and a negative Pap smear does not rule it out, this study revealed that abnormal Pap smears are significantly associated with high grade of tumor and stage II-IV endometrial carcinoma. However, they are not associated with patient age, depth of myometrial invasion or vascular invasion.     

Liquid-based cytology findings of glassy cell carcinoma of the cervix. Report of a case with histologic correlation and molecular analysis

BACKGROUND: Glassy cell carcinoma is a rare form of poorly differentiated carcinoma of the cervix with no obvious squamous or glandular differentiation. Its liquid-based cytology findings have not been described before. CASE: A 46-year-old Filipina presented with vaginal bleeding due to a bulky cervical tumor. The liquid-based cytology preparation was of moderate cellularity and contained small clusters of polygonal to elongated tumor cells admixed with amphophilic, granular, necrotic debris. The malignant cells possessed round to oval nuclei; a thin nuclear membrane; finely dispersed chromatin; prominent, solitary nucleoli; abundant, cyanophilic cytoplasm; and discrete cell borders. Occasional tumor cells showed phagocytosis of polymorphs. The background contained a mixed population of inflammatory cells. Eosinophils, though present, were not readily identified in the cytologic specimen. There was no evidence of dyskeratosis, cytoplasmic vacuolation or koilocytosis. Histologic and ultrastructural examination of the tumor biopsy showed classic features of glassy cell carcinoma. Molecular analysis using polymerase chain reaction and restriction fragment length polymorphism revealed the presence of human papillomavirus (HPV) DNA in the liquid-based cytology sample. The HPV genotype, however, did not belong to any of the commonly encountered prototypes. CONCLUSION: Glassy cell carcinoma of the cervix may show distinct, though subtle, cytomorphologic features in liquid-based preparations. The findings, however, are slightly different from those in conventional cervical smears. Awareness of this rare entity is important, as glassy cell carcinoma is often associated with more aggressive clinical behavior.     

Risk of significant gynaecological pathology in women with ?glandular neoplasia on cervical cytology

Risk of significant gynaecological pathology in women with ?glandular neoplasia on cervical cytology Objective: To review the risk of pre‐invasive and invasive gynaecological pathology in women referred with cervical cytology reporting ?glandular neoplasia. Methods: Review of the case notes of all women referred with cervical cytology reported as ?glandular neoplasia between January 1999 and December 2008 at two UK hospitals: Portsmouth Hospitals NHS Trust and Queen Mary’s Hospital Sidcup. The category of ‘borderline nuclear change in endocervical cells’, result code 8 according to the national health service cancer screening programme (NHSCSP), was excluded from the study. Results: A total of 200 women were identified using the hospitals’ pathology computer systems. Invasive carcinoma was found in 48 women (24%): 28 endocervical adenocarcinomas, eight squamous cell carcinomas (SCC), ten endometrial and two ovarian adenocarcinomas. Pre‐invasive neoplasia was found in 115 (57.5%), including 14 cervical glandular intraepithelial neoplasia (CGIN), 31 cervical intraepithelial neoplasia (CIN) grade 2/3 and 70 concomitant CGIN and CIN2/3. CIN1/HPV was found in 25, simple endometrial hyperplasia in three and no histological abnormality in three. Thirty‐four (70.8%) of 48 invasive carcinomas (of which 23 were endocervical adenocarcinomas) were in asymptomatic women investigated for abnormal cytology. Fourteen of 34 (41.4%) of those with ?glandular neoplasia thought to be endometrial were CGIN or CIN2/3. Colposcopic appearances were normal in 47.6% of women with pure cervical glandular neoplasia (adenocarcinoma or CGIN) compared with 12.8% with squamous cell lesions (CIN2/3 or SCC): P = 0.0001. Thus, colposcopy was more sensitive for detecting squamous cell abnormalities than their glandular counterparts. Although cervical adenocarcinomas are less amenable to prevention by screening than cervical SCC, in our study cervical cytology predominantly detected these abnormalities at their early asymptomatic stages. Conclusion: At least CIN2 was found in 81.5% in women referred with cervical cytology reporting ?glandular neoplasia. A thorough evaluation of the whole genital tract is needed if colposcopy is negative.     

Extrauterine malignancies. Role of Pap smears in diagnosis and management.

OBJECTIVE: To further elucidate the cytologic manifestations of extrauterine malignancies, to evaluate their possible distinction from primary cervical malignancies and to analyze their clinical significance and role in staging. STUDY DESIGN: Papanicolaou (Pap) smears in 33 cases with abnormal cells originating in histologically proven extrauterine carcinomas were evaluated. These cases came from the files of the Medical College of Pennsylvania and Lankenau Hospitals. RESULTS: Ovary, gastrointestinal tract and breast were the three most frequent primary sites, accounting for 28 of the 33 cases (85%). The histologic types encountered were adenocarcinoma, 29 cases (88%); mucoepidermoid carcinoma, 1 (3%); small cell carcinoma, 1 (3%); cloacogenic carcinoma and large cell lymphoma, 1 (3%). The following diagnoses were rendered at the time of initial evaluation: adenocarcinoma consistent with metastasis, 21 cases; carcinoma, primary versus metastatic, 2; adenocarcinoma, suspicious for endometrial primary, 2; suspicious for carcinoma, 1; and atypical glandular cells, 7. CONCLUSION: The yield for positive Pap smear diagnoses in extrauterine malignancies is best in patients with an established diagnosis of a primary neoplasm. The degree of tumor differentiation and extent of tumor involvement did not appear to correlate with diagnostic yield. There appeared to be no statistically significant association of tumor diathesis with primary versus metastatic carcinoma and presence or absence of documented local involvement of the endometrium, cervix or vagina. Therefore, while Pap smears can serve as a diagnostic tool in the evaluation of extrauterine malignancies, they are best utilized as an adjunct to tumor staging and patient management.
