MRI characteristics for predicting histological subtypes in patients with uterine cervical adenocarcinoma. Eur J Radiol 2023; 158:110612. [PMID: 36542931 DOI: 10.1016/j.ejrad.2022.110612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 10/17/2022] [Accepted: 11/14/2022] [Indexed: 12/14/2022]
Abstract
PURPOSE To evaluate the magnetic resonance imaging (MRI) findings of uterine cervical adenocarcinoma for predicting different histological subtypes. MATERIALS AND METHODS We retrospectively analyzed MRI findings of 76 consecutive patients with histopathologically-confirmed uterine cervical adenocarcinoma undergoing preoperative MRI examination. An experienced pathologist classified the histological subtypes based on World Health Organization's 2020 classification and into human papillomavirus (HPV)-associated adenocarcinomas (HPVAs, n = 54) (usual type and variants) and HPV-independent adenocarcinomas (HPVIs, n = 22) (gastric type adenocarcinoma (GAS), clear cell type, and other types). Different MRI variables were compared quantitatively and qualitatively between HPVA and HPVI and between GAS and non-GAS tumor types. RESULTS The maximum tumor diameter was significantly greater in HPVIs than HPVAs (41.9 ± 18.6 vs 32.7 ± 15.6 mm; p < 0.05). Heterogeneous enhancement on fat-suppressed gadolinium-enhanced T1-weighted images was more frequently seen in HPVIs than HPVAs (62 % vs 15 %; p < 0.01) and in GASs than non-GASs (78 % vs 16 %; p < 0.01). Also, infiltrative growth pattern (58 % vs 20 %; p < 0.05) and intratumoral cyst formation (83 % vs 47 %) (p < 0.05) were more frequent in GASs than non-GASs. CONCLUSIONS Compared with HPVAs, HPVIs tend to have a larger tumor size with heterogeneous enhancement, of which GASs frequently show infiltrative growth patterns with intratumoral cyst formation and heterogeneous enhancement.

Clinicopathological and prognostic significance of immunophenotypic characterization of endocervical adenocarcinoma using CLDN18, CDH17, and PAX8 in association with HPV status. Virchows Arch 2021; 480:269-280. [PMID: 34581850 DOI: 10.1007/s00428-021-03207-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 08/16/2021] [Accepted: 09/13/2021] [Indexed: 12/26/2022]
Abstract
In 2020, the WHO published a new system for classifying invasive endocervical adenocarcinoma based on histological features and high-risk human papillomavirus (HPV) infection. However, immunophenotypes of each histological subtype require further investigation. We immunohistochemically analyzed 66 invasive endocervical adenocarcinomas using three cell-lineage-specific markers: claudin 18 (CLDN18) for gastric, cadherin 17 (CDH17) for intestinal, and PAX8 for Müllerian epithelial cells. We identified five immunophenotypes of endocervical adenocarcinoma: gastric (21%); intestinal (14%); gastrointestinal (11%); Müllerian (35%); and not otherwise specified (NOS) (20%). Adenocarcinomas with gastric immunophenotype, characterized by aging (p = 0.0050), infrequent HPV infection (p < 0.0001), concurrent lobular endocervical glandular hyperplasia (p = 0.0060), lymphovascular invasion (p = 0.0073), advanced clinical stage (p = 0.0001), and the poorest progression-free (p < 0.0001) and overall (p = 0.0023) survivals, were morphologically compatible with gastric-type adenocarcinoma of the WHO 2020 classification. Conversely, most adenocarcinomas with Müllerian (91%) and intestinal (89%) immunophenotypes were HPV associated and morphologically compatible with usual- or intestinal-type adenocarcinomas of the WHO 2020 classification. The morphology of adenocarcinomas with gastrointestinal immunophenotype was intermediate or mixed between those of gastric and intestinal immunophenotypes; 57% were HPV associated. Adenocarcinomas with NOS immunophenotype were mainly HPV associated (85%) and histologically poorly differentiated. Multivariate analysis revealed that gastric (p = 0.008), intestinal + gastrointestinal (p = 0.0103), and NOS (p = 0.009) immunophenotypes were independent predictors of progression-free survival. Immunophenotypes characterized by CLDN18, CDH17, and PAX8 exhibited clinicopathological relevance and may improve the diagnostic accuracy and prognostic value of conventional histological classification.

Cytomorphologic Features of Gastric-Type Endocervical Adenocarcinoma in Liquid-Based Preparations. Acta Cytol 2020; 65:56-66. [PMID: 33152741 DOI: 10.1159/000511003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Accepted: 08/17/2020] [Indexed: 01/25/2023]
Abstract
OBJECTIVE Gastric-type endocervical adenocarcinoma (GAS) is a recently described, uncommon, and aggressive tumor with distinct morphologic features and HPV-independent etiology. Data on GAS in liquid-based cytology (LBC) Papanicolaou (Pap) test preparations from a North American patient population are scant. We systematically assessed the cytomorphologic characteristics of GAS in LBC from patients in Ontario and examined if glandular cell nuclear area could represent a readily assessable feature which may aid in GAS detection. STUDY DESIGN Pap test slides preceding the diagnosis of GAS were retrieved locally or requested from outside laboratories. A structured review of 15 cytomorphologic features was performed using the available LBC Pap test slides of GAS and a set of usual-type endocervical adenocarcinomas (UEA). Morphometry of the glandular cell nuclear area was performed, and normalized values were compared to UEA and benign endocervical cells. RESULTS At least 1 Pap test (5 ThinPrep®, 11 SurePath®, and 1 direct smear) was available for 14 patients. Original LBC Pap test diagnoses were negative for intraepithelial lesion or malignancy (NILM) (7), adenocarcinoma/carcinoma (6), atypical glandular cells (2), and adenocarcinoma in situ (1). Review detected abnormal glandular cells in 6/7 NILM cases. Honeycomb-like sheets, nuclear enlargement, and microvesicular cytoplasm were the single most common architectural, nuclear, and cytoplasmic features, respectively. Microvesicular cytoplasm (100 vs. 17%), honeycomb-like sheets (87 vs. 8%), prominent nucleoli (93 vs. 25%), and anisonucleosis (93 vs. 50%) were most discriminatory for GAS versus UEA, respectively. Yellow mucin, intranuclear cytoplasmic pseudoinclusions, and goblet/Paneth-like cells were uncommon, but unique for GAS. Glandular cell nuclear area normalized to neutrophils was found to be significantly increased in GAS compared to benign endocervical cells. CONCLUSIONS GAS is under-recognized and may mimic reactive endocervical cells. Awareness of the tumor type and its cytomorphology is critical for early detection. Identification of glandular cells with uniform nuclear enlargement in conjunction with any of the other cytologic features may help avoid false-negative Pap results. Neutrophils may serve as convenient size reference and visual aid.

Rare coincidence of intraductal papillary mucinous neoplasm and type 1 autoimmune pancreatitis. Clin J Gastroenterol 2020; 13:1315-1321. [PMID: 32594422 DOI: 10.1007/s12328-020-01162-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Accepted: 06/18/2020] [Indexed: 01/06/2023]
Abstract
The present case involved a 60-year-old man with autoimmune pancreatitis (AIP). While his AIP was in remission for 6 years, a follow-up CE-CT revealed a dilated main pancreatic duct (MPD) and an enhanced mural nodule. Fluorodeoxyglucose uptake was positive on positron emission tomography. Endoscopic retrograde pancreatography showed a filling defect of the MPD, and pancreatoscopy revealed a nodule partially covered with papillary lesions. Although a repeat biopsy revealed no evidence of malignancy, we speculated that there was a high likelihood of main-duct-type intraductal papillary mucinous neoplasm (IPMN)-derived carcinoma concomitant with AIP. Subsequently, the patient underwent subtotal stomach-preserving pancreaticoduodenectomy. A surgical specimen showed a 35 mm protuberant papillary lesion with abundant stroma, located in the main duct of the pancreas. Further histological evaluation revealed that the nodule was predominantly composed of IPMN with low-grade dysplasia, which was accompanied by abundant IgG4-positive lymphoplasmacytic infiltration, and fibrosis existed predominantly around the IPMN. The epithelium of the cyst showed mucinous hyperplasia with focal papillary structures of gastric phenotype (MUC5A+, MUC6+, MUC1-, MUC2-, CDX-). After surgical resection, we did not find any imaging evidence suggesting a recurrent tumor and AIP relapse in the remnant pancreas. In conclusion, we report a case of IPMN coincidentally found in a patient with type 1 AIP. Active AIP may exaggerate the morphology of IPMN, and careful evaluation should be performed to select appropriate management.

Immunophenotype analysis using CLDN18, CDH17, and PAX8 for the subcategorization of endocervical adenocarcinomas in situ: gastric-type, intestinal-type, gastrointestinal-type, and Müllerian-type. Virchows Arch 2020; 476:499-510. [PMID: 31932920 DOI: 10.1007/s00428-019-02739-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2019] [Revised: 12/10/2019] [Accepted: 12/22/2019] [Indexed: 12/16/2022]
Abstract
A classification system for invasive endocervical adenocarcinoma (ECA) focusing on high-risk human papillomavirus (HPV) detection has been recently developed. However, precursor lesions of each ECA subtype and immunohistochemical markers that effectively subcategorize ECAs with gastric and intestinal differentiation have not been fully described. Here, we aimed to subcategorize endocervical adenocarcinoma in situ (AIS) by immunophenotype and to characterize the histopathology of each AIS subtype. We immunohistochemically analyzed 36 AIS and 25 lobular endocervical glandular hyperplasia (LEGH) samples using three cell lineage-specific markers (CLDN18, gastric epithelial cells; CDH17, intestinal epithelial cells; and PAX8, Müllerian epithelial cells). The AISs were immunophenotypically classified as gastric-type (G-AIS; n = 2), intestinal-type (I-AIS; n = 10), gastrointestinal-type (GI-AIS; n = 3), Müllerian-type (M-AIS; n = 18), and AIS, not otherwise specified (AIS-NOS; n = 3). All 25 LEGHs were categorized as gastric-type. G-AIS had pale eosinophilic or clear cytoplasm with a small amount of apical mucin and fewer mitotic bodies. I-AIS comprised various numbers of goblet cell-type tumor cells. GI-AIS showed intermediate or mixed features of G-AIS and I-AIS. M-AIS, as with the usual-type ECA, was typically characterized by mucin depletion; however, several lesions had abundant cytoplasmic mucin. High-risk HPV was detected in most AISs but was negative in 100% (2/2) of G-AIS, 10% (1/10) of I-AIS, and 6% (1/18) of M-AIS lesions. In summary, the AIS subtypes defined by immunophenotype had distinct histopathological and etiological characteristics. Thus, immunophenotyping with CLDN18, CDH17, and PAX8 might improve the diagnostic accuracy of histopathological classifications of ECAs.

Clinicopathological characteristics of patients with mucinous adenocarcinoma of the uterine cervix: A retrospective study of 21 cases. J Gynecol Obstet Hum Reprod 2019; 48:319-327. [PMID: 30807852 DOI: 10.1016/j.jogoh.2019.02.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 01/28/2019] [Accepted: 02/19/2019] [Indexed: 11/16/2022]
Abstract
OBJECTIVES Few studies in the literature take into account the WHO's 2014 redefinition of the characteristics of mucinous adenocarcinoma of the uterine cervix. Our objective was to describe the characteristics of a group of these patients. MATERIAL AND METHODS This was a retrospective descriptive study of patients diagnosed between 1 January 2005 and 31 May 2016 in three hospitals in Lyon, France. All the cases of cervical adenocarcinoma were reanalysed by an expert in gynaecological pathology to retain the mucinous subtypes as defined in the 2014 WHO classification. We analysed their clinical and pathological characteristics. RESULTS Among the 82 cases of cervical adenocarcinoma, 21 (26%) were diagnosed as mucinous. Ten were gastric type, of which four were in the extremely well differentiated form of minimal deviation adenocarcinomas, six were intestinal type, two were signet-ring cell type, and three were not otherwise specified. The patients' mean age was 42 years and 18 patients were premenopausal. The revealing symptom was metrorrhagia in eight cases (38%) and mucinous vaginal discharge in four (19%). Fifteen (72%) of the cervical smear were abnormal. Five (31%) of the 16 patients with gastric or intestinal type adenocarcinoma had a specific radiological presentation: multiple cysts of the uterine isthmus, visible on ultrasound and with T2 hyperintensity on MRI. CONCLUSION Mucinous adenocarcinoma is a rare form of cervical cancer that can be confused with other pathological types. It can be detected using cervical smears and should be suspected in cases of mucinous discharge and characteristic MRI features.

Abstract
Cancer of the uterine cervix is the fourth most common cancer in women worldwide, and the fourth leading cause of cancer death in women. Squamous cell carcinoma is the first type of cervical cancer (about 75% of cases), and adenocarcinoma the second. Adenocarcinoma of the uterine cervix were redefined in the 2014 WHO classification. Endocervical adenocarcinoma, usual type, is the mose common. Mucinous adenocarcinoma were classified by this classification into different subtypes: gatric type, intestinal type and signet-ring cell type. This literature review shows the caracteristics of these various subtypes of cervical cancer, little known. These are physiopathological, clinical, cytological histological, pronostic caracteristics, and their treatments.

Trefoil factor family 2 protein: a potential immunohistochemical marker for aiding diagnosis of lobular endocervical glandular hyperplasia and gastric-type adenocarcinoma of the uterine cervix. Virchows Arch 2018; 474:79-86. [PMID: 30324235 DOI: 10.1007/s00428-018-2469-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2018] [Revised: 09/16/2018] [Accepted: 10/03/2018] [Indexed: 11/29/2022]
Abstract
Gastric-type adenocarcinoma (GA) is an aggressive subtype of cancer of the uterine cervix. Several immunohistochemical markers for gastric mucins, such as mucin 6 (MUC6) and N-acetylglucosamine α1 → 4galactose → R (αGlcNAc-R), which is recognized by HIK1083 antibody, have been introduced for diagnosis of GA and lobular endocervical glandular hyperplasia (LEGH). However, MUC6 is also expressed in normal endocervical glands and HIK1083 antibody has limited availability. Trefoil factor family 2 protein (TFF2) is secreted by gastric, but not normal endocervical glands. Here, we evaluated TFF2 immunostaining for detection of a gastric immunophenotype in endocervical glandular lesions. We compared TFF2, αGlcNAc-R, and MUC6 expression in 103 endocervical glandular lesions: LEGH (n = 23), adenocarcinoma in situ/microinvasive adenocarcinoma (AIS-MIA) (n = 29), and invasive adenocarcinoma (usual type [UA], n = 26; GA, n = 11; intestinal type [IA], n = 2; signet ring cell type [Sig], n = 2; and mucinous adenocarcinoma not otherwise specified [NOS], n = 10). TFF2 and αGlcNAc-R expression was completely concordant in each subtype: LEGH (100%), AIS-MIA (44.8%), UA (26.9%), GA (90.9%), IA (100%), Sig (0%), and NOS (20%). TFF2 staining scores were significantly correlated with those of αGlcNAc-R in these lesions. TFF2 and αGlcNAc-R immunoreactivity was present in cytoplasmic mucins and luminal secretions. TFF2 and αGlcNAc-R were not expressed in the normal endocervical glands. MUC6 was frequently expressed in normal endocervical glands and endocervical glandular lesions. Endocervical adenocarcinomas sometimes stained only for MUC6. TFF2 is a promising immunohistochemical marker and its identification in uterine cervical secretion is a potentially useful diagnostic test for endocervical glandular lesions with gastric differentiation.

Gastric gland mucin-specific O-glycan expression decreases as tumor cells progress from lobular endocervical gland hyperplasia to cervical mucinous carcinoma, gastric type. Virchows Arch 2018; 473:305-311. [PMID: 29845361 DOI: 10.1007/s00428-018-2381-6] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Revised: 05/09/2018] [Accepted: 05/16/2018] [Indexed: 01/27/2023]
Abstract
Gastric gland mucin-specific O-glycans are unique in having α1,4-linked N-acetylglucosamine (αGlcNAc) attached to MUC6. We previously reported decreased expression of αGlcNAc relative to MUC6 in gastric and pancreatic neoplasms, but its significance in cervical glandular lesions remained unclear. Here, we analyzed MUC5AC, MUC6, αGlcNAc, and p16 expression in 9 lesions of mucinous carcinoma, gastric type with minimal deviation adenocarcinoma (GAS-MDA), 5 of GAS with nonMDA (GAS-nonMDA), 14 of typical lobular endocervical gland hyperplasia (LEGH), and 5 of atypical LEGH (33 total lesions). All 33 were MUC5AC-positive. Moreover, all 14 typical LEGH, 5 atypical LEGH, 8 of 9 GAS-MDA, and 3 of 5 GAS-nonMDA were MUC6-positive. All 14 typical LEGH, 2 of 5 atypical LEGH, 3 of 9 GAS-MDA, and 1 of 5 GAS-nonMDA were αGlcNAc-positive. The proportion of αGlcNAc-positive atypical LEGH or GAS-MDA or GAS-nonMDA lesions was significantly smaller than that seen in typical LEGH lesions (P < 0.001 and P < 0.01, respectively). Of 33 lesions, 32 were p16-negative. Furthermore, when we evaluated MUC6 and αGlcNAc immunoreactivity semi-quantitatively in all 33 lesions, in typical LEGH and GAS-MDA, the immunohistochemical score for αGlcNAc was significantly lower than that for MUC6 (P < 0.01). We did not observe significantly decreased αGlcNAc expression relative to MUC6 in typical LEGH lesions. These studies suggest that αGlcNAc expression decreases as typical LEGH progresses to GAS. Given the difficulty in distinguishing MDA and atypical LEGH from typical LEGH in H.E. staining, we propose that immunohistochemical analysis of αGlcNAc and MUC6 could be useful.

Gastric type mucinous endocervical adenocarcinoma of the uterine cervix: very rare and interesting case. Obstet Gynecol Sci 2017; 61:165-169.

Abstract
Gastric type mucinous endocervical adenocarcinomas of the uterine cervix (GAC) are a newly classified mucinous subtype with morphologically in 2014, WHO. They have a much more aggressiveness and show unusual metastatic patterns compared to usual type endocervical adenocarcinoma. They tend to present at higher stage and even in stage I, they have worse survival. Therefore, differential diagnosis of GAC from the usual type of endocervical adenocarcinoma is very important because they are related to a significant risk of recurrence and decreased 5-year disease-specific survival. Besides, GACs are mostly not associated with human papillomavirus (HPV) infection and p16 immunohistochemistry is also typically negative in GAC that is HPV-unassociated tumor. We report a very rare and interesting case of stage IB1 GAC with negative HPV DNA and p16.

Cystic micropapillary neoplasm of peribiliary glands with concomitant perihilar cholangiocarcinoma. World J Gastroenterol 2016; 22:2391-2397.

Abstract
We report a case of a 75-year-old man with cystic micropapillary neoplasm of peribiliary glands detected preoperatively by radiologic examination. Enhanced computed tomography showed a low-density mass 2.2 cm in diameter in the right hepatic hilum and a cystic lesion around the common hepatic duct. Under a diagnosis of perihilar cholangiocarcinoma, right hepatectomy with caudate lobectomy and bile duct resection were performed. Pathological examination revealed perihilar cholangiocarcinoma mainly involving the right hepatic duct. The cystic lesion was multilocular and covered by columnar lining epithelia exhibiting increased proliferative activity and p53 nuclear expression; it also contained foci of micropapillary and glandular proliferation. Therefore, the lesion was diagnosed as a cystic micropapillary neoplasm of peribiliary glands and resembled flat branch-type intraductal papillary mucinous neoplasm of the pancreas. Histological examination showed the lesion was discontinuous with the perihilar cholangiocarcinoma. Immunohistochemistry showed the cystic neoplasm was strongly positive for MUC6 and that the cholangiocarcinoma was strongly positive for MUC5AC and S100P. These results suggest these two lesions have different origins. This case warrants further study on whether this type of neoplasm is associated with concomitant cholangiocarcinoma as observed in pancreatic intraductal papillary mucinous neoplasm with concomitant pancreatic duct adenocarcinoma.

Abstract
A 77-year-old woman complained of epigastralgia, and a tumor (5 cm in diameter) of the gallbladder neck was detected by image analysis. Following cholecystectomy, the tumor was pathologically diagnosed as intraductal papillary neoplasm (IPN), gastric type, with associated invasive carcinoma. About 10 mo later, intraluminal multiple masses (3 foci, up to 1.8 cm) were noted in the extrahepatic bile duct, and the resected specimen showed that all tumors had similar gross and microscopic features as seen in gallbladder IPN without invasion, and they were synchronous multiple lesions. This case showed a papillary tumor of the gallbladder of gastric phenotype, and confirmed that the gallbladder is a target of IPN in addition to the bile ducts.
