Abstract
AIMS To stratify the risk of cervical precancers (high-grade squamous intraepithelial lesion (HSIL) and adenocarcinoma in situ (AIS)) and cancers (squamous cell carcinoma (SCC) and adenocarcinoma) based on distinct high-risk human papillomavirus (hrHPV) genotypes as well as age groups among women with atypical squamous cells of undetermined significance (ASC-US) and hrHPV+results. METHODS In total, 2292 cases of ASC-US/hrHPV+ with immediate follow-up biopsy results were included in the study for prevalence analysis. RESULTS Overall, 12.2% women with ASC-US /hrHPV+ had HSIL+ while 0.22% had AIS+ lesions. The HPV-16+ group (31.6%) showed significantly higher prevalence of HSIL+ squamous lesions than other genotype groups (p<0.0001). The prevalence of SCC is significantly higher in HPV-16+ (1.8%) or HPV-18/45+ (1.1%) group than women in other genotype groups (0.1%) (p<0.0001). The HPV-18/45+ group (1.7%) showed significantly higher prevalence of AIS+ glandular lesions than other genotype groups (p=0.003). In addition, SCC prevalence was significantly higher in age over 50 group than that in age under 50 group (1.2% vs 0.2%, p=0.012). CONCLUSION Women with ASC-US/hrHPV+ are at significant risk of cervical precancers and cancers; notably, HPV-16+ group has a higher risk of HSIL squamous lesions and SCC while HPV-18/45+ group has a higher risk of AIS+ glandular lesions. In addition, the older patient group (>50 years) has a significantly higher risk of SCC. Therefore, HPV genotyping as well as patient age need to be considered in the clinical management of patient.

Abstract
Serous tubal intraepithelial carcinoma (STIC) is the fallopian tube precursor lesion for most cases of pelvic high-grade serous carcinoma (HGSC). To date, the morphologic, molecular, and clinical heterogeneity of STIC and a less atypical putative precursor lesion, termed serous tubal intraepithelial lesion, has not been well characterized. Better understanding of precursor heterogeneity could impact the clinical management of women with incidental STICs (without concurrent carcinoma) identified in cases of prophylactic or opportunistic salpingectomy. This study analyzed morphologic and molecular features of 171 STICs and 21 serous tubal intraepithelial lesions. We assessed their histologic features, Ki-67 and p53 staining patterns, and genome-wide DNA copy number alterations. We classified all precursor lesions into 2 morphologic subtypes, one with a flat surface (Flat) and the other characterized by budding, loosely adherent, or detached (BLAD) morphology. On the basis of pathology review by a panel of 8 gynecologic pathologists, we found 87 BLAD, 96 Flat, and 9 indeterminate lesions. As compared with Flat lesions, BLAD lesions were more frequently diagnostic of STIC ( P <0.0001) and were found concurrently with HGSC ( P <0.0001). BLAD morphology was also characterized by higher Ki-67 proliferation index ( P <0.0001), presence of epithelial stratification ( P <0.0001), and increased lymphocyte density ( P <0.0001). BLAD lesions also exhibited more frequent DNA copy number gain/amplification at the CCNE1 or CMYC loci canonical to HGSCs ( P <0.0001). Both BLAD morphology and STIC diagnoses are independent risk factors for an elevated Ki-67 proliferation index. No correlation was observed between BLAD and Flat lesions with respect to patient age, presence of germline BRCA1/2 mutation, or p53 staining pattern. These findings suggest that tubal precursor lesions are morphologically and molecularly heterogeneous, laying the foundation for further studies on the pathogenesis of HGSC initiation and identifying histologic features predictive of poor patient outcomes.

Abstract
Exosomes, extracellular vesicles released by cells, hold potential as diagnostic markers for the early detection of lung cancer. Despite their clinical promise, current technologies lack rapid and effective means to discriminate between exosomes derived from adenocarcinoma in situ (AIS) and early-stage invasive adenocarcinoma (IAC). This challenge arises from the intrinsic structural heterogeneity of exosomes, necessitating the development of advanced methodologies for precise differentiation. Here, we demonstrate a novel approach for plasma exosome detection utilizing multi-receptor surface-enhanced Raman spectroscopy (SERS) technology to differentiate between AIS and early-stage IAC. To accomplish this, we synthesized a stable and uniform two-dimensional SERS substrate (BC/Au NPs film) by fabricating gold nanoparticles onto bacterial cellulose. We then enhanced its capabilities by introducing multi-receptor SERS functionality via modifying the substrate with both low-specificity and physicochemical-selective molecules. Furthermore, by strategically combining all capturer-exosome SERS spectra, comprehensive "combined-SERS spectra" are reconstructed to enhance spectral variations of the exosome. Combining these features with partial least squares regression-discriminant analysis (PLS-DA) modeling significantly improved discriminatory accuracy, achieving 90% sensitivity and 95% specificity in distinguishing AIS from early-stage IAC. Our developed SERS sensor provides an effective method for early detection of lung cancer, thereby paving a new way for innovative advancements in diagnosing lung cancer.

Abstract
BACKGROUND In Taiwan, lung cancers occur predominantly in never-smokers, of whom nearly 60% have stage IV disease at diagnosis. We aimed to assess the efficacy of low-dose CT (LDCT) screening among never-smokers, who had other risk factors for lung cancer. METHODS The Taiwan Lung Cancer Screening in Never-Smoker Trial (TALENT) was a nationwide, multicentre, prospective cohort study done at 17 tertiary medical centres in Taiwan. Eligible individuals had negative chest radiography, were aged 55-75 years, had never smoked or had smoked fewer than 10 pack-years and stopped smoking for more than 15 years (self-report), and had one of the following risk factors: a family history of lung cancer; passive smoke exposure; a history of pulmonary tuberculosis or chronic obstructive pulmonary disorders; a cooking index of 110 or higher; or cooking without using ventilation. Eligible participants underwent LDCT at baseline, then annually for 2 years, and then every 2 years up to 6 years thereafter, with follow-up assessments at each LDCT scan (ie, total follow-up of 8 years). A positive scan was defined as a solid or part-solid nodule larger than 6 mm in mean diameter or a pure ground-glass nodule larger than 5 mm in mean diameter. Lung cancer was diagnosed through invasive procedures, such as image-guided aspiration or biopsy or surgery. Here, we report the results of 1-year follow-up after LDCT screening at baseline. The primary outcome was lung cancer detection rate. The p value for detection rates was estimated by the χ2 test. Univariate and multivariable logistic regression analyses were used to assess the association between lung cancer incidence and each risk factor. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of LDCT screening were also assessed. This study is registered with ClinicalTrials.gov, NCT02611570, and is ongoing. FINDINGS Between Dec 1, 2015, and July 31, 2019, 12 011 participants (8868 females) were enrolled, of whom 6009 had a family history of lung cancer. Among 12 011 LDCT scans done at baseline, 2094 (17·4%) were positive. Lung cancer was diagnosed in 318 (2·6%) of 12 011 participants (257 [2·1%] participants had invasive lung cancer and 61 [0·5%] had adenocarcinomas in situ). 317 of 318 participants had adenocarcinoma and 246 (77·4%) of 318 had stage I disease. The prevalence of invasive lung cancer was higher among participants with a family history of lung cancer (161 [2·7%] of 6009 participants) than in those without (96 [1·6%] of 6002 participants). In participants with a family history of lung cancer, the detection rate of invasive lung cancer increased significantly with age, whereas the detection rate of adenocarcinoma in situ remained stable. In multivariable analysis, female sex, a family history of lung cancer, and age older than 60 years were associated with an increased risk of lung cancer and invasive lung cancer; passive smoke exposure, cumulative exposure to cooking, cooking without ventilation, and a previous history of chronic lung diseases were not associated with lung cancer, even after stratification by family history of lung cancer. In participants with a family history of lung cancer, the higher the number of first-degree relatives affected, the higher the risk of lung cancer; participants whose mother or sibling had lung cancer were also at an increased risk. A positive LDCT scan had 92·1% sensitivity, 84·6% specificity, a PPV of 14·0%, and a NPV of 99·7% for lung cancer diagnosis. INTERPRETATION TALENT had a high invasive lung cancer detection rate at 1 year after baseline LDCT scan. Overdiagnosis could have occurred, especially in participants diagnosed with adenocarcinoma in situ. In individuals who do not smoke, our findings suggest that a family history of lung cancer among first-degree relatives significantly increases the risk of lung cancer as well as the rate of invasive lung cancer with increasing age. Further research on risk factors for lung cancer in this population is needed, particularly for those without a family history of lung cancer. FUNDING Ministry of Health and Welfare of Taiwan.

Abstract
OBJECTIVES/PURPOSE The reproducibility and sensitivity of image-based colposcopy is low, but agreement on lesion presence and location remains to be explored. Here, we investigate the interobserver agreement on lesions on colposcopic images by evaluating and comparing marked lesions on digitized colposcopic images between colposcopists. METHODS Five colposcopists reviewed images from 268 colposcopic examinations. Cases were selected based on histologic diagnosis, i.e., normal/cervical intraepithelial neoplasia (CIN)1 ( n = 50), CIN2 ( n = 50), CIN3 ( n = 100), adenocarcinoma in situ ( n = 53), and cancer ( n = 15). We obtained digitized time-series images every 7-10 seconds from before acetic acid application to 2 minutes after application. Colposcopists were instructed to digitally annotate all areas with acetowhitening or suspect of lesions. To estimate the agreement on lesion presence and location, we assessed the proportion of images with annotations and the proportion of images with overlapping annotated area by at least 4 (4+) colposcopists, respectively. RESULTS We included images from 241 examinations (1 image from each) with adequate annotations. The proportion with a least 1 lesion annotated by 4+ colposcopists increased by severity of histologic diagnosis. Among the CIN3 cases, 84% had at least 1 lesion annotated by 4+ colposcopists, whereas 54% of normal/CIN1 cases had a lesion annotated. Notably, the proportion was 70% for adenocarcinoma in situ and 71% for cancer. Regarding lesion location, there was no linear association with severity of histologic diagnosis. CONCLUSION Despite that 80% of the CIN2 and CIN3 cases were annotated by 4+ colposcopists, we did not find increasing agreement on lesion location with histology severity. This underlines the subjective nature of colposcopy.

OBJECTIVE To determine the baseline and cumulative risk of cervical intraepithelial neoplasia (CIN)3 and invasive cervical cancer in participants referred to colposcopy with high-grade cytology and METHODS The authors linked administrative databases including cytology, pathology, cancer registries, and physician billing history to identify participants referred to colposcopy between January 2012 and December 2013 with high-grade cytology (atypical squamous cells [ASC]-H, high-grade squamous intraepithelial lesion [HSIL], invasive squamous cell carcinoma, adenocarcinoma, atypical glandular cells [AGC], adenocarcinoma in situ) and had RESULTS Among 4,168 women referred to colposcopy for ASC-H, HSIL, squamous cell carcinoma, or adenocarcinoma, the 3- and 5-year CIN3 incidence rates were 17.7%/20.0% no biopsy, 13.0%/15.1% negative biopsy, and 18.9%/20.0% low-grade squamous intraepithelial lesion (LSIL) biopsies. The 3- and 5-year incidences of invasive cancer were: 1.25%/1.68% no biopsy, 0.78%/1.04% negative biopsy, and 0%/0% LSIL biopsy. When the initial cytology was AGC/adenocarcinoma in situ (n = 944), the 3- and 5-year rates of CIN3 were 7.42%/8.39% no biopsy, 7.41%/9.26% negative biopsy, and 7.69%/7.69% LSIL biopsy. The invasive cancer rates were 1.12%/1.54% no biopsy, 0.46%/0.46% negative biopsy, and 0.0%/0.0% LSIL biopsy. By screening cytology, participants referred for HSIL had the highest 3- and 5-year rates of CIN3 (18.9% and 21%) compared with AGC (7.22%/8.28%) and ASC-H (15.5%/18%). The 3- and 5-year invasive cancer rates were 1.38%/1.75% HSIL, 0.85%/1.17% AGC, and 0.91%/1.36% ASC-H. CONCLUSIONS In participants referred for high-grade cytology where colposcopy shows

Abstract
AIMS The invasive pattern in HPV-associated endocervical adenocarcinoma (HPVA) has prognostic value. Non-destructive (pattern A) HPVA has excellent prognosis mirroring adenocarcinoma in-situ (AIS). However, the rare occurrence of ovarian spread in these tumours suggests aggressiveness in a subset of patients with these otherwise indolent lesions. We hypothesise that AIS/pattern A HPVA with ovarian metastases are biologically different than metastatic destructively invasive HPVA. METHODS AND RESULTS Samples from patients with HPVA and synchronous or metachronous metastases were retrieved and reviewed to confirm diagnosis and determine the Silva pattern in the primary lesion. For each case, normal tissue, cervical tumour and at least one metastasis underwent comprehensive sequencing using a 447-gene panel. Pathogenic single-nucleotide variants and segmental copy-number alterations (CNA), tumour mutational burden and molecular signatures were evaluated and compared between primary and metastases and among invasive pattern categories. We identified 13 patients: four had AIS/pattern A primaries, while nine had pattern B/C tumours. All AIS/pattern A lesions had metastasis only to ovary; 50% of patients with ovarian involvement, regardless of invasive pattern, also had involvement of the endometrium and/or fallopian tube mucosa by HPVA. In the ovary, AIS/pattern A HPVA showed deceptive well-differentiated glands, often with adenofibroma-like appearance. Conversely, pattern C HPVAs consistently showed overt infiltrative features in the ovary. Sequencing confirmed the genetic relationship between primary and metastatic tumours in each case. PIK3CA alterations were identified in three of four AIS/pattern A HPVAs and three of eight pattern B/C tumours with sequenced metastases. Pattern C tumours showed a notably higher number of CNA in primary tumours compared to pattern A/B tumours. Only one metastatic AIS/pattern A HPVA had a novel pathogenic variant compared to the primary. Conversely, five of eight pattern B/C tumours with sequenced metastases developed novel pathogenic variants in the metastasis not seen in the primary. All four AIS/pattern A patients were alive and free of disease at 31, 47, 58 and 212 months after initial diagnosis. Conversely, cancer-related death was documented in five of nine pattern B/C patients with follow-up at 7, 20, 20, 43 and 87 months. CONCLUSION Morphologically and genomically, AIS/pattern A HPVA with secondary ovarian involvement appears distinct from destructively invasive tumours. In at least a subset of these cases, ovarian spread appears to occur via trans-Mullerian superficial extension, different from the stromal and lymphatic vascular spread typical of more aggressive tumours (pattern C). These differences may explain the indolent outcome observed in the rare subset of patients with AIS/pattern A HPVA and ovarian metastasis. Our data underscore the potential for conservative surgical management approaches to pattern A HPVA.

Abstract
OBJECTIVES (1) To determine the role of human papillomavirus (HPV) testing after excisional treatment of cervical precancer. (2) To determine clinical factors associated with persistence of cervical precancer post-treatment. METHODS A retrospective chart review was conducted including patients who had a loop electrosurgical excision procedure (LEEP) for cervical precancer (cervical intraepithelial neoplasia 3/adenocarcinoma in situ/high-grade squamous intraepithelial lesions [HSIL]). All patients treated between 2016 and 2018 at a tertiary centre colposcopy unit were included. Persistence/recurrence of disease was defined as high-grade cytology or histology identified during the time of follow-up. Univariate and multivariate regression models were performed to identify factors associated with persistence/recurrence and HPV positivity at exit testing. RESULTS A total of 284 patients were included. The median follow-up time was 19 months. Of the LEEP specimens, 90.8% (n = 258) demonstrated HSIL and 3.9% (n = 11) had adenocarcinoma in situ. 28.5% (n = 81) of the LEEP specimens had positive margins. In follow-up, 72.9% had negative cytology, 17.6% had atypical squamous cells of undetermined significance/low-grade SIL, 1.8% had atypical squamous cells, HSIL cannot be excluded/low-grade SIL-H, and 6.7% had HSIL. At the final follow-up, 27.8% (n = 79) were HPV+. Overall rate of persistence/recurrence was 11.3% (n = 32); median time to persistence/recurrence was 6.5 months. Multivariate regression models demonstrated that follow-up HPV positivity (OR = 22.0) and positive margins (OR = 3.7) were significantly associated with persistence/recurrence. Similarly, in univariate regression models, positive margins were significant (OR = 2.2) for predicting HPV positivity in exit testing. CONCLUSIONS Persistence/recurrence of precancer can occur due to incomplete treatment of lesions by local excision and by the persistence of HPV infection. Surveillance strategies for women treated for cervical precancer require a risk-based approach and should rely on HPV testing.

Abstract
Pancreatic ductal adenocarcinoma (PDAC), a highly lethal disease with limited therapeutic options, may benefit from repurposing of FDA-approved drugs in preventive or interceptive strategies in high-risk populations. Previous animal studies demonstrated that the use of metformin and statins as single agents at relatively high doses restrained PDAC development. Here, four-week-old mice expressing KrasG12D in all pancreatic lineages (KC mice) and fed an obesogenic high fat, high calorie diet that promotes early PDAC development were randomized onto low dosage metformin, simvastatin, or both drugs in combination administered orally. Dual treatment attenuated weight gain, fibro-inflammation, and development of advanced PDAC precursor lesions (pancreatic intraepithelial neoplasia [PanIN]-3) in male KC mice, without significant effect in females or when administered individually. Dual-treated KC mice had reduced proliferation of PanIN cells and decreased transcriptional activity of the Hippo effectors, YAP and TAZ, which are important regulators of PDAC development. Metformin and simvastatin also synergistically inhibited colony formation of pancreatic cancer cells in vitro. Together, our data demonstrated that a combination of low doses of metformin and simvastatin inhibits PDAC development and imply that both drugs are promising agents for being tested in clinical trials for preventing pancreatic cancer progression.

Abstract
RATIONALE Copious vaginal discharge is a frequent manifestation of reproductive tract infections. However, when little effect can obtain treated as vaginitis, cervical disease should be highly suspected. PATIENT CONCERNS A 41-year-old woman had suffering from abnormally increased vaginal discharge without any other signs of discomfort for the past 4 years. A lot of medical examinations and treatment of vaginosis were administered, resulting in unclear diagnosis and little effect. DIAGNOSES Cervical adenocarcinoma. INTERVENTIONS Gynecological examination, vaginal microbiome culture, and primary cervical cancer screening were negative, and a positron emission tomography revealed an increased 18F-fluorodeoxyglucose metabolism in the local cervix. After a thorough description, the patient demanded a hysterectomy and bilateral salpingo-oophorectomy. OUTCOMES Histopathological evaluation confirmed adenocarcinoma in situ of the uterine cervix. LESSONS The correct diagnosis of symptomatic patients with increased vaginal discharge is challenging. Human papillomavirus-negative patients presenting profuse watery vaginal discharge with an abnormal signal of cervix lesion on positron emission tomography or magnetic resonance imaging should be alert to cervical adenocarcinoma. Deep-seated cervical biopsy, conization, or even hysterectomy is conducive to early diagnosis, treatment and improvement of prognosis.

Abstract
PURPOSE We aimed to evaluate and compare the growth patterns among pathological types of inde- terminate subsolid nodules in patients without a history of cancer as observed on computed tomography (CT). METHODS This retrospective study included 77 consecutive patients with 80 indeterminate subsolid nod- ules on unenhanced thin-section CT. Subsolid nodules were classified into 2 growth pattern groups based on volume: growth (n = 35) and non-growth (n = 42). According to the pathologi- cal diagnosis, subsolid nodules were further subdivided into 3 groups: adenocarcinoma in situ (growth, n = 8 vs. non-growth, n = 22), minimally invasive adenocarcinoma (n = 14 vs. n = 15), and invasive adenocarcinoma (n=13 vs. n=5). Kaplan-Meier and Cox proportional hazards regres- sion analyses were performed to identify the risk factors for subsolid nodules growth. The CT findings of the 35 subsolid nodules in the growth group were compared among the 3 pathologi- cal groups. RESULTS In the growth group, the overall mean volume doubling time and mass doubling time (MDT) were 811.5 days and 616.5 days, respectively. Patient's age (odds ratio=1.041, P=.045) and CT subtype of non-solid nodule and part-solid nodule (odds ratio=3.430, P=.002) could predict subsolid nodule growth. The baseline volume, mass, and mean CT value were larger in the inva- sive adenocarcinoma group than in the adenocarcinoma in situ group (all P < .01). The shortest volume doubling time was observed in the invasive adenocarcinoma group, followed by the minimally invasive adenocarcinoma group and the adenocarcinoma in situ group. A shorter mass doubling time was observed in the minimally invasive adenocarcinoma group than in the adenocarcinoma in situ group (all P < .02). CONCLUSION As age increases, the risk of pulmonary subsolid nodule growth increases by 4% each year, and part-solid nodules have a 3 times higher risk of growth compared to non-solid nodules in patients with no history of cancer. Subsolid nodules with more aggressive pathological charac- teristics grow at a faster rate.

Abstract
INTRODUCTION Although the cytological diagnostic criteria for cervical squamous and glandular lesions are established by the Bethesda System for Reporting Cervical Cytology, the reproducibility of the diagnosis of these lesions has been shown to be variable in previous studies. At best, occasional good kappa (κ) values were reached both inter- and intra-observerly. Generally, consensus on high-grade lesions has been better compared to milder changes. METHODS Altogether, 167 conventional Pap smears from 50 patients with histologically confirmed endocervical adenocarcinomas (EAC) and adenocarcinomas in situ (AIS) and from 28 patients with histologically proven high-grade intraepithelial lesions were analyzed by four cytopathologists. Twenty of the smears were later re-evaluated by the same cytopathologists. κ-values between cytopathologists in the categories of squamous versus glandular, negative for intraepithelial lesion or malignancy (NILM), atypical, and preneoplastic/neoplastic were calculated. The diagnostic Pap smears of EAC and AIS with best and worst consensus between observers were then morphologically analyzed. RESULTS The reproducibility ranged from poor to substantial. The overall κ-values between the four cytopathologists were 0.412, 0.314, 0.272, and 0.082, respectively, in the categories of preneoplastic/neoplastic, squamous versus glandular, NILM, and atypical. Overall intra-observer κ-values were correspondingly 0.491, 0.616, 0.345, and 0.241. In the diagnostic smears of AIS and EAC, the nuclear size >2 times the normal and nuclear pleomorphism were the commonest features associated with good diagnostic consensus and the lack of nuclear enlargement and degenerative changes were associated with poor consensus. CONCLUSIONS The reproducibility of preneoplasia/neoplasia diagnoses was better than that of atypia and NILM both in the inter- and intra-observer part in this study. In the smears from AIS and EAC patients, general neoplasia-associated features were more common in samples with good agreement by the four cytopathologists of the neoplastic nature and the endocervical origin of the lesion.

Abstract
OBJECTIVE The aim of the study was to evaluate the pregnancy outcomes of women who underwent conservative management of adenocarcinoma in situ (AIS). MATERIALS AND METHODS We conducted a retrospective chart review of patients diagnosed with AIS at a single tertiary institution between January 1, 1991, and December 31, 2019. We collected demographic data, AIS-specific information, and fertility outcomes and performed bivariate analyses to compare demographic characteristics and AIS-specific information between patients with and without hysterectomy after diagnosis. Patients with conservative management who achieved pregnancy were described. RESULTS Among 87 patients with AIS, 38 (44%) underwent a hysterectomy within 6 months of diagnosis and 49 (56%) underwent conservative management. Six of 19 patients (32%) had residual AIS despite undergoing definitive management after an excisional procedure with negative margins and negative endocervical curettage (ECC). Nine of 19 patients (47%) had residual AIS after an excisional procedure with positive margins and/or a positive ECC. Patients who opted for conservative management were younger (median = 31.6 [interquartile range = 27.4-34.9] vs 38.5 y [32.3-44.8 y], p < .001) and nulligravid. Among patients with conservative management, there were 15 pregnancies and 14 live births (29%). Seven were preterm, although 2 were for medical indications. CONCLUSIONS Residual AIS in patients with negative margins and ECC leading to definitive hysterectomy (32%) and the rate of preterm birth (36%) were higher than previous reports and nationally reported rates. However, only 1 patient had a preterm birth before 34 weeks. These findings reflect important information for counseling patients who elect for conservative management of AIS.

Abstract
BACKGROUND Due to further developments in the diagnosis of glandular cervical changes with the definition of several new entities, the exact classification of these can only be achieved with the help of cytomorphology and additive methods. OBJECTIVES AND METHODS The aim of this work is to give an overview of the status and future perspectives of cytomorphological diagnostics and biomarkers in this setting. Our own expertise and literature data were considered and evaluated. We especially covered the benign group including microglandular hyperplasia, tubal metaplasia, and reactive withdrawal induced changes, as well as adenocarcinoma in situ of usual type and invasive adenocarcinoma of usual type. RESULTS AND CONCLUSIONS Immunocytochemical markers may occasionally take a role in the evaluation of benign endocervical glandular proliferations, the mainstay of their interpretation occurs morphologically in the conventional routinely stained smears. Adenocarcinoma in situ of usual type has very characteristic cytological criteria, which are reproducible in daily work, and p16 positivity is a very useful marker for this HPV-related lesion. The present classification of invasive adenocarcinomas of the endocervix requires knowledge of new immunohistochemical and molecular technologies. Due to HPV vaccination we can expect a decrease of HPV associated adenocarcinomas and a relative increase of HPV negative, clinically more aggressive adenocarcinomas. The cytological features of some groups of non-HPV-associated adenocarcinomas are not specific. In these instances, the different biomarkers are more helpful.
