RESUMO

BACKGROUND: The US Food and Drug Administration supports innovations to facilitate new indications for high-risk human papillomavirus testing. This report describes the retrospective testing of stored specimens and analysis of existing data to efficiently and cost-effectively support a new indication for the Onclarity human papillomavirus assay (Becton, Dickinson and Company, BD Life Sciences - Integrated Diagnostic Solutions, Sparks, MD). The performance of this index test was compared with that of a predicate test, the cobas human papillomavirus assay (Roche Diagnostics, Indianapolis, IN). Both human papillomavirus assays are based on real-time polymerase chain reaction platforms that detect the presence of 14 high-risk human papillomavirus genotypes. The predicate assay reports human papillomavirus types 16 and 18 as individual results and the other 12 human papillomavirus genotypes as 1 pooled result. The index assay reports 9 independent results (human papillomavirus types 16, 18, 31, 33/58, 35/39/68, 45, 51, 52, and 56/59/66). Both the index and predicate assays are approved by the Food and Drug Administration for cervical cancer screening, but at the time that this study was initiated, the index human papillomavirus assay was not approved for use with cervical specimens collected in PreservCyt (Hologic, Inc, San Diego, CA) liquid-based cytology media. OBJECTIVE: The performance of the index human papillomavirus assay was compared with that of the predicate human papillomavirus assay for the detection of cervical intraepithelial neoplasia grades 2 or greater and 3 or greater (≥CIN2 or ≥CIN3) using PreservCyt liquid-based cytology specimens collected from women aged 21 to 65 years. In addition, the ability of the index test's extended genotyping to stratify ≥CIN2 and ≥CIN3 risks, using these specimens, was evaluated. STUDY DESIGN: The New Mexico HPV Pap Registry was used to select an age- and cytology-stratified random sample of 19,879 women undergoing opportunistic cervical screening and follow-up in routine clinical practice across New Mexico. A subset (n = 4820) of PreservCyt specimens was selected from 19,879 women for paired testing by the index and predicate human papillomavirus assays within age and cytology strata and included women with or without cervical biopsy follow-up. Point estimate differences and ratios were calculated for cervical disease detection and positivity rates, respectively, with 95% confidence intervals to determine statistical significance. The cumulative risk of ≥CIN2 or ≥CIN3, with up to 5-year follow-up, was estimated for the index assay using Kaplan-Meier methods. RESULTS: The 5-year cumulative ≥CIN3 detection rates were 5.6% for the index assay and 4.6% for the predicate assay (difference, 1.0%; 95% confidence interval, 0.5%-1.5%). The ≥CIN3 positivity rates within <1 year were 95.3% for the index assay and 94.5% for the predicate assay (ratio, 1.01; 95% confidence interval, 0.98-1.06). The ≥CIN3 cumulative positivity rates for the index and predicate assays were also similar at 5 years. Among cases of ≥CIN3, the positive agreement rates between the index and predicate assays for human papillomavirus types 16 and 18 were 100.0% (95% confidence interval, 95.0%-100.0%) and 90.9% (95% confidence interval, 62.3%-98.4%), respectively. Human papillomavirus type 16 carried the highest ≥CIN2 or ≥CIN3 risk, followed by human papillomavirus types 18/31/33/58/52/45 and human papillomavirus types 35/56/59/51/56/59/66. CONCLUSION: The index and predicate human papillomavirus assays demonstrated equivalent performance, and extended human papillomavirus genotyping, using the index assay, provided effective ≥CIN2 and ≥CIN3 risk stratification, supporting a new indication for use of the index assay with PreservCyt.

RESUMO

PURPOSE: This study evaluated epidemiologic and immune factors associated with pathologic complete response (pCR), breast cancer-specific survival (BCSS) and disease-free survival (DFS) outcomes in inflammatory (IBC) and locally advanced breast cancer (LABC) patients. METHODS: Tumor-infiltrating lymphocytes (TILs) and CD20+ B-cell frequencies (CD20+), and PD-L1 expression on tumor (PD-L1+carcinoma cells) and immune (PD-L1+TILs) cells were analyzed by immunohistochemistry along with clinicopathologic factors as modifiers of pCR and outcomes in 221 IBC and 162 LABC patients. Analysis included Kaplan-Meier curves and Cox proportional hazard models. RESULTS: IBC and LABC display similar levels of TILs, CD20+, and combined CD20+ and PD-L1+TILs (CD20+PD-L1+TILs), while LABC contained more PD-L1+TILs and PD-L1+ carcinoma cells. Absence of lymphovascular involvement, high TILs, PD-L1+ carcinoma cells, and combined CD20+ and PD-L1+ carcinoma cells correlated with pCR in IBC and LABC patients. High PD-L1+TILs correlated with pCR only in LABC; less lymph node involvement at diagnosis, CD20+ and CD20+PD-L1+TILs correlated with pCR only in IBC (P < 0.04, all comparisons). Achievement of pCR in IBC and LABC patients correlated with BCSS and DFS (P < 0.02). In multivariate analyses, pCR remained an independent prognostic factor of improved DFS in IBC and LABC patients, but of BCSS in only LABC. CD20+PD-L1+TILs remained an independent prognostic factor of improved DFS and BCSS only in IBC. CONCLUSION: CD20+PD-L1+TILs are an independent prognostic biomarker of improved outcomes in IBC, but not LABC. Selecting IBC patients by CD20 and PD-L1 status could stratify patients and potentially identify those in whom activating CD20 agents and anti-PD-1/PD-L1 therapy could be explored.

RESUMO

OBJECTIVES: Human papillomavirus (HPV) testing for cervical screening has been shown to increase the yield of precancerous disease and reduce the incidence of cervical cancer more than cytology alone. Here we document the state-wide uptake of co-testing with HPV and cytology in women aged 30-64 years as recommended by national and international bodies. METHODS: Registry-based study of all screening cytology and HPV tests in New Mexico from 2008 to 2019 among women aged 21-64 years, with a focus on cytology negative tests to distinguish co-testing from reflex HPV testing to triage equivocal or mildly abnormal cytology. RESULTS: A total of 1,704,055 cervical screening tests from 681,440 women aged 21-64 years in the state of New Mexico were identified. The proportion of screening tests which were co-tests rose from 5.6% in 2008 to 84.3% in 2019 among women aged 30-64 years with a marked change from the near exclusive use of the Hybrid Capture II HPV test, (a signal amplified test method) to the use of target amplified HPV tests. The largest increases were seen between 2013 and 2015, reflecting the introduction and adoption of new clinical guidelines. Increases in co-testing were also seen in younger women. CONCLUSIONS: Co-testing is now well established in women aged 30-64 years, but smaller increases have also been seen at younger ages, although this is not currently recommended. The impact of co-testing on cervical disease outcomes and number of colposcopies and biopsies in routine population settings remain important, especially in young women.

RESUMO

The amount of normal tissue that should be excised during breast conserving surgery is widely debated. Tissue adjacent to breast tumors, although histologically normal, possesses many of the molecular abnormalities found in tumor tissues. Here, we propose that the ideal physical distance for a surgical margin may not be universal. Rather, an adequate surgical margin likely varies from patient to patient, depending on the biology of the tissue that remains after surgery. J. Surg.

RESUMO

Females are under-represented as departmental chairs in academic medical centers and identifying ways to increase their numbers in this position would be useful. A previous study of women chairs of pathology showed that 35% of permanent chairs had previously been interim chairs, suggesting that the interim position was a common pathway for women to advance to a permanent chair position. We sought to determine whether it might also be true for males and if not, possible reasons for the difference. Between January 2016 and June 2022, the Association of Pathology Chairs identified 50 people who had served as interim pathology department chairs. Males served as interim chairs more often than females (66% vs 34%), but, within this time frame, female interim chairs were more likely to become permanent chairs than males (47% of females compared to 27% of males). To better understand the difference in the rate of advancement from interim to permanent chair, we surveyed the 50 individuals who had served as interim chairs to explore gender differences in backgrounds, reasons for serving as interim chairs and reasons for seeking or not seeking the permanent chair position. No significant gender differences were found except that male interim chairs were older (59.2 years) than female interim chairs (50.4 years). This study affirms that serving as an interim chair is a common pathway for females to become permanent chairs, while it is less so for males, although the reasons for this difference could not be determined.

RESUMO

Previous studies have shown that a field of genetically altered but histologically normal tissue extends 1 cm or more from the margins of human breast tumors. The extent, composition and biological significance of this field are only partially understood, but the molecular alterations in affected cells could provide mechanisms for limitless replicative capacity, genomic instability and a microenvironment that supports tumor initiation and progression. We demonstrate by microarray, qRT-PCR and immunohistochemistry a signature of differential gene expression that discriminates between patient-matched, tumor-adjacent histologically normal breast tissues located 1 cm and 5 cm from the margins of breast adenocarcinomas (TAHN-1 and TAHN-5, respectively). The signature includes genes involved in extracellular matrix remodeling, wound healing, fibrosis and epithelial to mesenchymal transition (EMT). Myofibroblasts, which are mediators of wound healing and fibrosis, and intra-lobular fibroblasts expressing MMP2, SPARC, TGF-ß3, which are inducers of EMT, were both prevalent in TAHN-1 tissues, sparse in TAHN-5 tissues, and absent in normal tissues from reduction mammoplasty. Accordingly, EMT markers S100A4 and vimentin were elevated in both luminal and myoepithelial cells, and EMT markers α-smooth muscle actin and SNAIL were elevated in luminal epithelial cells of TAHN-1 tissues. These results identify cellular processes that are differentially activated between TAHN-1 and TAHN-5 breast tissues, implicate myofibroblasts as likely mediators of these processes, provide evidence that EMT is occurring in histologically normal tissues within the affected field and identify candidate biomarkers to investigate whether or how field cancerization contributes to the development of primary or recurrent breast tumors.

RESUMO

BACKGROUND: Lung is the most common site of distant metastasis for patients with head and neck squamous cell carcinoma (HNSCC). However, differentiating second primary lung cancers from metastasis may be difficult for p16 negative HNSCC. CASE: We describe a case of oral cavity squamous cell carcinoma (SCC) who was found to have lung nodule and hilar lymphadenopathy (LAD) after surgery and radiation therapy. Hilar node was consistent with SCC however, it was difficult to differentiate second primary lung cancer and metastasis from oral cavity SCC. Next-generation sequencing was done for the primary oral cavity and the hilar node. Both samples had the same type of TP53 mutation and variants of unknown significance suggesting metastatic HNSCC. He was treated with a chemotherapy regimen for metastatic HNSCC. CONCLUSION: Molecular studies can help to differentiate metastasis from second primary lung cancers for p16 negative HNSCC.

RESUMO

The Association of Pathology Chairs, an organization of American and Canadian academic pathology departments, has a record percent of women department chairs in its ranks (31%), although still not representative of the percent of women pathology faculty (43%). These women chairs were surveyed to determine what had impeded and what had facilitated their academic advancement before becoming chairs. The 2 most frequently identified impediments to their career advancement were heavy clinical loads and the lack of time, training, and/or funding to pursue research. Related to the second impediment, only one respondent became chair of a department which was in a top 25 National Institutes of Health-sponsored research medical school. Eighty-nine percent of respondents said that they had experienced gender bias during their careers in pathology, and 31% identified gender bias as an important impediment to advancement. The top facilitator of career advancement before becoming chairs was a supportive family. Strikingly, 98% of respondents have a spouse or partner, 75% have children, and 38% had children younger than 18 when becoming chairs. Additional top facilitators were opportunities to attend national meetings and opportunities to participate in leadership. Previous leadership experiences included directing a clinical service, a residency training program, and/or a medical student education program. These results suggest important ways to increase the success of women in academic pathology and increasing the percent of women department chairs, including supporting a family life and providing time, encouragement and resources for research, attending national meetings, and taking on departmental leadership positions.

RESUMO

GPR30 is a novel G protein-coupled estrogen receptor (ER) associated with metastases in breast cancer (BC) and poor survival in endometrial and ovarian tumors. The association of GPR30 expression with inflammatory breast cancer (IBC), an aggressive and commonly hormone-independent form of BC, has not been studied. GPR30, ER, progesterone receptor (PR), epidermal growth factor receptor (EGFR), and HER-2 expression were assessed by immunohistochemistry (and FISH for HER-2) in 88 primary IBCs. GPR30 expression was correlated with patient overall survival (OS), disease-free survival (DFS), pathologic variables, and other biomarkers. GPR30 expression was found in 69% of IBC cases. ER, PR, HER-2, and EGFR were found in 43, 35, 39, and 34% of IBC cases, respectively. GPR30 expression correlated inversely with ER expression (P = 0.02). Co-expression of ER and GPR30 was found in 24% of IBC samples; 19% expressed only ER and 46% expressed only GPR30. Univariate analysis showed no association between GPR30 expression and OS or DFS. However, co-expression of ER and GPR30 was associated with improved OS (P < 0.03) and marginally with DFS (P < 0.06); the absence of both ER and GPR30 was associated with worse OS and DFS (P = 0.03 for both). Multivariate analysis identified ER as an independent prognostic factor of OS (P = 0.008) and DFS (P = 0.02). The majority of IBC tumors are GPR30-positive, suggesting that estrogen signaling may be active in ER-negative IBC patients. These findings suggest potential new therapeutic targets for IBC such as novel endocrine agents or direct modulation of GPR30.

RESUMO

A 55-year-old female equestrian presented with a 3.5 cm painful left perineal mass. Histologic examination of the excised mass showed a poorly circumscribed mesenchymal proliferation involving fibroadipose and fibrous tissue. The lesion consisted of a bland spindle cell proliferation with areas of fat necrosis, hemosiderin-laden macrophages, multinucleated histiocytes, and extracellular hyalinization with degenerative features. Immunohistochemical studies showed vimentin positivity and no staining for actin, desmin, and CD34. On the basis of clinical, morphologic, and immunostaining findings, the lesion was consistent with a diagnosis of perineal nodular induration. This lesion has been described almost exclusively in avid male cyclists with repetitive perineal trauma. A similar etiology of longstanding and repetitive perineal trauma from horseback riding is postulated for this case. Perineal nodular induration should be considered in the differential diagnosis of perineal masses in women with persistent perineal trauma, such as equestrianism, as well as other similar sport activities.

RESUMO

CONTEXT.­: Lower Anogenital Squamous Terminology (LAST) standardization recommended p16INK4a immunohistochemistry (p16 IHC) for biopsies diagnosed morphologically as cervical intraepithelial neoplasia (CIN) grade 2 (CIN2) to classify them as low-grade or high-grade squamous intraepithelial lesions (HSILs). OBJECTIVE.­: To describe the relationships of p16 IHC and other biomarkers associated with cervical cancer risk with biopsy diagnoses. DESIGN.­: A statewide, stratified sample of cervical biopsies diagnosed by community pathologists (CPs), including 1512 CIN2, underwent a consensus, expert pathologist panel (EP) review (without p16 IHC results), p16 IHC interpretation by a third pathology group, and human papillomavirus (HPV) genotyping, results of which were grouped hierarchically according to cancer risk. Antecedent cytologic interpretations were also available. RESULTS.­: Biopsies were more likely to test p16 IHC positive with increasing severity of CP diagnoses, overall (Ptrend ≤ .001) and within each HPV risk group (Ptrend ≤ .001 except for low-risk HPV [Ptrend < .010]). All abnormal grades of CP-diagnosed biopsies were more likely to test p16 IHC positive with a higher HPV risk group (Ptrend < .001), and testing p16 IHC positive was associated with higher HPV risk group than testing p16 IHC negative for each grade of CP-diagnosed biopsies (P < .001). p16 IHC-positive, CP-diagnosed CIN2 biopsies were less likely than CP-diagnosed CIN3 biopsies to test HPV16 positive, have an antecedent HSIL+ cytology, or to be diagnosed as CIN3+ by the EP (P < .001 for all). p16 IHC-positive, CP-diagnosed CIN1 biopsies had lower HPV risk groups than p16 IHC-negative, CP-diagnosed CIN2 biopsies (P < .001). CONCLUSIONS.­: p16 IHC-positive, CP-diagnosed CIN2 appears to be lower cancer risk than CP-diagnosed CIN3. LAST classification of "HSIL" diagnosis, which includes p16 IHC-positive CIN2, should annotate the morphologic diagnosis (CIN2 or CIN3) to inform all management decisions, which is especially important for young (<30 years) women diagnosed with CIN2 for whom surveillance rather than treatment is recommended.

RESUMO

PURPOSE: To assess telomere DNA content (TC) and the number of sites of allelic imbalance (AI) as a function of breast cancer progression. EXPERIMENTAL DESIGN: TC and AI were determined in 54 histologically normal tissues, 10 atypical ductal hyperplasias (ADH), 122 in situ ductal carcinomas (DCIS) and 535 invasive carcinomas (Stage I-IIIA). RESULTS: TC was altered in ADH lesions (20%), DCIS specimens (53%) and invasive carcinomas (51%). The mean number of sites of AI was 0.26 in histologically normal group tissue, increased to 1.00 in ADH, 2.94 in DCIS, and 3.07 in invasive carcinomas. All groups were statistically different from the histologically normal group (P < 0.001 for each); however, there was no difference between DCIS and the invasive groups. CONCLUSIONS: Genomic instability increases in ADH and plateaus in DCIS without further increase in the invasive carcinomas, supporting the notion that invasive carcinomas evolve from or in parallel with DCIS.

RESUMO

OBJECTIVES: GPR30 is a 7-transmembrane G protein-coupled estrogen receptor that functions alongside traditional estrogen receptors to regulate cellular responses to estrogen. Recent studies suggest that GPR30 expression is linked to lower survival rates in endometrial and breast cancer. This study was conducted to evaluate GPR30 expression in ovarian tumors. METHODS: GPR30 expression was analyzed using immunohistochemistry and archival specimens from 45 patients with ovarian tumors of low malignant potential (LMP) and 89 patients with epithelial ovarian cancer (EOC). Expression, defined as above or below the median (intensity times the percentage of positive epithelial cells) was correlated with predictors of adverse outcome and survival. RESULTS: GPR30 expression above the median was observed more frequently in EOC than in LMP tumors (48.3% vs. 20%, p=0.002), and in EOC was associated with lower 5-year survival rates (44.2% vs. 82.6%, Log-rank p<0.001). Tumor grade and FIGO stage, the other significant predictors of survival, were used to stratify cases into "high risk" and "low risk" groups. The 5-year survival rate for "low risk" EOC (all grade 1 and Stage I/II, grade 2) was 100%. In "high risk" EOC (all grade 3 and Stage III/IV, grade 2), the difference in 5-year survival by GPR 30 expression was significant (33.3% vs. 72.4%, p=0.001). CONCLUSIONS: The novel estrogen-responsive receptor GPR30 is preferentially expressed in "high risk" EOC and is associated with lower survival rates. Further investigation of GPR30 as a potential target for therapeutic intervention in high risk EOC is warranted.

RESUMO

OBJECTIVE: Receptors for estrogen (ER) and progesterone (PR) are prognostic indicators for a variety of endocrine tumors including breast and endometrial. This study was conducted to determine if ER and PR expression patterns are predictive of outcome in patients with epithelial ovarian cancer (EOC) or ovarian low malignant potential (LMP) tumors. METHODS: ER and PR protein levels were assessed by immunohistochemistry in 45 LMP and 89 EOC samples. Patterns of ER/PR expression (individually and combinations of ER-/PR-, ER+/PR-, ER-/PR+, and ER+/PR+) were correlated with standard prognostic factors of overall survival (OS) in this patient population. RESULTS: For patients with EOC, the 5-year OS per ER-/PR+, ER+/PR-, ER+/PR+, and ER-/PR- expression was 83%, 79%, 61%, and 48%, respectively, and these differences were statistically significant. In multivariate analyses, ER/PR expression patterns were found to be independent predictors of OS, as were the classical prognostic factors of grade, stage, debulking, and chemotherapy response to treatment. In patients with mucinous LMP tumors, ER and PR were absent. Because no LMP patients died of disease during the studied period, no correlation analysis with OS could be performed. CONCLUSIONS: Patterns of ER/PR expression provide prognostic information in EOC. Additional studies evaluating hormonal inhibition may help personalize the therapy of patients with ovarian cancer.

RESUMO

Klippel-Trenaunay syndrome (KTS) is a rare disorder involving a triad of cutaneous capillary malformations (port-wine stain), varicose veins or venous malformations, and bony or soft tissue hyperplasia of an extremity. It is one of many heterogeneous disorders known as overgrowth syndromes that are characterized by either generalized or localized somatic overgrowth. Overgrowth syndromes each have unique clinical, behavioral, and genetic features, but some of these features overlap, causing diagnostic difficulty. Cutaneous manifestations, however, can be key to distinguishing the various syndromes. We present a patient with an unusual variant of KTS consisting of right upper extremity hyperplasia, lymphedema, and cutaneous and visceral lymphangiomas. We review several closely related syndromes and discuss the differential diagnosis of limb hyperplasia.

BACKGROUND: An anal histological high-grade squamous intraepithelial lesion (hHSIL) is an anal cancer precursor. Experts recommend Dacron swab anal cytology as a primary screen for anal hHSILs, especially among human immunodeficiency virus-infected and -uninfected men who have sex with men (MSM). Studies have shown that Dacron cytology inaccurately predicts anal hHSILs and results in unnecessary diagnostic procedures. Nylon-flocked (NF) swabs have been shown to trap pathogens and cells well. Thus, this study compared test characteristics of anal cytology using NF and Dacron swab collection protocols to predict anal hHSILs. METHODS: A single-visit, randomized clinical trial compared NF and Dacron swab anal cytology specimens to predict high-resolution anoscopy and biopsy-diagnosed anal hHSILs. Data for 326 gay men, bisexual men, other MSM, and male-to-female transgender women contributed descriptive and tabular statistics with which unadjusted and fully adjusted logistic regression models were constructed. The models estimated the odds of hHSILs, test accuracy (area under the curve [AUC]) and sensitivity, and specificity as well as the positive and negative predictive values of abnormal NF and Dacron cytology for predicting hHSILs. RESULTS: In the fully adjusted model, the sensitivities for NF and Dacron cytology were nearly equal (48% vs 47%), but the specificity was higher with NF cytology (76% vs 69%). Comparisons of the areas under receiver operating characteristic curves showed that NF cytology alone predicted hHSILs better than the covariate model (AUC, 0.69 vs 0.63; P = .02), but NF and Dacron cytology comparisons showed no statistically significant differences (AUC, 0.69 vs 0.67; P = .3). CONCLUSIONS: NF cytology and Dacron cytology provide modest sensitivity, but NF cytology has higher specificity and accuracy, and this is important for lowering the costs of population-based screening.

RESUMO

Screening for cervical cancer by the Papanicolaou or Pap test is a complex and multistep process. From the clinician's examination room to the cytology laboratory, the Pap test involves numerous laboratory personnel, different test types, and the possibility of computer-assisted screening and ancillary testing. The laboratory has in place well-defined procedures to ensure both error reduction and specimen quality to produce reliable Pap test results. The Bethesda System 2001 provides guidance and criteria for both specimen adequacy and diagnostic criteria. Understanding laboratory procedures in Pap testing aids in clinical understanding of tests and results and contributes to effective communication between the pathologist and those involved in patient management of women with cervical abnormalities.

RESUMO

BACKGROUND: Men who have sex with men (MSM) are at increased risk for anal cancer. In cervical cancer screening, patterns of repeated cytology results are used to identify low- and high-risk women, but little is known about these patterns for anal cytology among MSM. METHODS: We analyzed Multicenter AIDS Cohort Study (MACS) data for MSM who were offered anal cytology testing annually (HIV-positive) or every 2 years (HIV-negative) for 4 years. RESULTS: Following an initial negative (normal) cytology, the frequency of a second negative cytology was lower among HIV-positive MSM with CD4 ≥ 500 (74%) or CD4 < 500 (68%) than HIV-negative MSM (83%) (p < 0.001). After an initial abnormal cytology, the frequency of a second abnormal cytology was highest among HIV-positive MSM with CD4 < 500 (70%) compared to CD4 ≥ 500 (53%) or HIV-negative MSM (46%) (p = 0.003). Among HIV-positive MSM with at least three results, 37% had 3 consecutive negative results; 3 consecutive abnormal results were more frequent among CD4 < 500 (22%) than CD4 ≥ 500 (10%) (p = 0.008). CONCLUSIONS: More than one-third of HIV-positive MSM have consistently negative anal cytology over three years. Following abnormal anal cytology, a repeated cytology is commonly negative in HIV-negative or immunocompetent HIV-positive men, while persistent cytological abnormality is more likely among HIV-positive men with CD4 < 500.

RESUMO

OBJECTIVE: This study was undertaken to evaluate the relationship between GPR30, classical steroidal receptor expression, and clinical outcome in patients with endometrial carcinoma. STUDY DESIGN: Immunohistochemistry was used to investigate the expression of GPR30, estrogen, progesterone, epidermal growth factor receptors and Ki-67 in 47 consecutive consenting patients with endometrial carcinoma diagnosed between 1997 and 2001. Results were correlated with clinical and pathologic predictors of adverse outcome and survival. RESULTS: GPR30 correlated positively with epidermal growth factor receptor (P = .005), but negatively with progesterone (P = .05) receptor expression. GPR30 overexpression occurred more frequently in tumors with deep myometrial invasion, high-grade, biologically aggressive histologic subtypes, and advanced stage. In patients with GPR30 overexpression, survival was significantly poorer (65.2% vs 100%, P = .005). CONCLUSION: GPR30 represents an alternative estrogen-responsive receptor that is overexpressed in tumors where estrogen and progesterone receptors are downregulated, and in high-risk endometrial cancer patients with lower survival rates.
