11032 Background: GISTs are the most common mesenchymal tumors of the digestive tract. As of recent, new links are being made between GISTS and secondary malignancies. However, whether the coexistence of GISTs with other tumors is stochastic, or the result of related pathogenetic mechanisms is still unknown. Methods: We retrospectively reviewed clinical and molecular features from all GIST patients with second tumors treated in seven Italian GIST reference centers. Qualitative variables were compared using the Fisher exact test. Results: Clinical data of 184 patients with diagnosis of GIST were evaluated. Median age at diagnosis was 66 years, KIT exon 11 resulted the most frequent mutation (73%) while seven patients (3.8%) had a genetic syndrome. The most common primary GIST localizations were stomach (54%) and small intestine (33%). Second tumors arose mostly from gastrointestinal and genitourinary tract. Fourtythree patients had two primary tumors other than GIST and five patients had three other primary malignancies. According to Miettinen criteria, 45% of non-metastatic patients at diagnosis belong to low or very low-risk classes. We highlighted a significant correlation (P=0.002) between risk class and second/third tumor localization, with considerably high percentage of GI second malignancies in low/very low risk GISTs (table). Conclusions: The high frequency of second/third tumors reported in low and very low GIST calls for a careful follow-up also in these patients. Furthermore, this population requires further genetic investigation, NGS analysis is ongoing. [Table: see text]

e23518 Background: In patients with GIST, literature reports a risk of second primary tumors between 4.5% and 33% with different distribution in the worldwide. The network of 7 italian EURACAN centers has collected clinical and molecular features of GIST patients with second primary tumors. Methods: We reviewed the clinical characteristics of 201 patients with GIST and second primary tumors in order to evaluate association between risk of dead and each possible factor, using Kaplan meier curve, log-rank test and Cox model for Hazard Ratio and it’s interval Confidence 95% estimation. Furthermore, NGS analysis ( 56 gene onco panel) in 72 patients with GIST was performed. Results: On the basis of the significant correlation previously observed between the Miettinen risk criteria of GIST (low/very low) and the incidence of second primary tumors (gastrointestinal tumors),P < 0.001 (Abstr 11032 ASCO 2019), we observed in these patients a median age of diagnosis of GIST of 68, with prevalent gastric site localization ( KIT exon 11 mutation), NF1 and Lynch (kit/pdgfra WT) syndromes in the low risk subgroup. The more frequent site of second epithelial tumor in gastrointestinal tract was the colon followed by gastric, pancreatic and biliary tract. In patients with GIST with low-very low risk according Miettinen classification, after a median follow-up period of 25 years, we have observed that the gastroenteric site of second tumors occurrence is significantly related to the survival (p < .0003). In the NGS analysis of the GIST we observed the pathogenetic somatic mutations in the following genes: BRCA 2 (p.Thr2125fs), but germline test negative, TP53 (p.Arg192*,p.Gly244Ser,p.His168Leu), RET (p.Lys120Asn, p.His168Leu, p.Thr930Met ), NRAS (p.Gly134Asp), CTNNB1 (p.Ser45Phe), MSH6 (P.Ala164Val), SMARCB1 (p.Arg192), VHL (p.Gly93Val), PTEN(p.Val158Ile, p.Asn323fs), STK1I (p.Arg40Cys), SMO (p.Glu194Lys), EGFR (p.Gly721Asp), ATM (p.Asp2708Asn), ERBB4 (p.Asn181Ile). Conclusions: In our analysis patients with GIST (low-very low classes according to Miettinen) have significant risk to death because of second primary tumors in gastrointestinal tract. Specific attention to gastrointestinal screening during the follow-up of GIST (low and very low risk) is required.

Lymphovascular Space Invasion

ObjectiveThe prognostic significance of lymphovascular space invasion (LVSI) in patients with early-stage endometrial cancer is not established. We sought to determine if LVSI status in patients with early-stage low-risk endometrial cancer correlates with recurrence and survival.MethodsThe records of all women who underwent hysterectomy for primary treatment of endometrial cancer from January 2006 through January 2011 at 1 academic institution were reviewed. Patients with grade 1 or 2 endometrioid histology, myometrial invasion less than 50%, and disease confined to the uterus (clinical International Federation of Obstetrics and Gynecology stage IA) were analyzed. Fisher exact test and the Wilcoxon rank-sum test were applied to compare patients with and without LVSI. Recurrence-free survival (RFS) and overall survival (OS) were calculated using the Kaplan-Meier method.ResultsTwo hundred forty patients met the inclusion criteria. Forty (16.7%) had LVSI. Ninety-one patients (37.9%) underwent lymphadenectomy. Median tumor size was 30 mm in patients with and 26 mm in patients without LVSI (P = 0.150). Thirty patients (12.5%) received adjuvant therapy. Site of recurrence did not differ between patients with and without LVSI. Patients with LVSI were more likely to have myometrial invasion (P < 0.001), postoperative pathologic grade 2 disease (P < 0.001), to undergo lymphadenectomy (P = 0.049) and receive adjuvant therapy (P < 0.001). The 5-year cumulative incidence of recurrence was 3.8% in the no-LVSI group and 14.2% in the LVSI group (P = 0.053). The presence of LVSI was significantly associated with worse RFS (P = 0.002) and OS (P = 0.013).ConclusionsPatients with low-risk endometrial cancer and LVSI have worse RFS and OS despite being more likely to undergo lymphadenectomy and adjuvant therapy.

SummaryA retrospective study was done to determine the incidence of and the risk factors predisposing to clinical venous thromboembolism (VTE) in patients treated for high grade gliomas. Medical records of 68 consecutive patients diagnosed and treated at Saint Francis Hospital and Medical Center from January 1986 to June 1991 were reviewed. The follow up was to time of death or at least 6 months (up to December 1991). All clinically suspected episodes of VTE were confirmed by objective tests. Sixteen episodes of VTE were detected in 13 patients for an overall episode rate of 23.5%. Administration of chemotherapy (p = 0.027, two tailed Fisher exact test) and presence of paresis (p = 0.031, two tailed Fisher exact test) were statistically significant risk factors for the development of VTE. Thrombotic events were more likely to occur in the paretic limb and this difference was statistically significant (p = 0.00049, chi square test, with Yates correction). No major bleeding complications were seen in the nine episodes treated with long term anticoagulation.We conclude that venous thromboembolic complications are frequently encountered in patients being treated for high grade gliomas and the presence of paresis and the administration of chemotherapy increases the risk of such complications.

Background: There has been a striking increase in electronic cigarette (EC) use in the United States. The beliefs and practices toward ECs among physicians are unknown. Objective: The purpose of this study was to investigate EC practice patterns among allergists, pulmonologists, and primary care physicians. Methods: An anonymous survey was sent to physicians. The survey contained 32 questions and addressed issues related to demographics, cessation counseling behaviors, personal use, and knowledge and beliefs about ECs. Statistical analysis was performed by using analysis of variance, the Pearson χ2 test, Fisher exact test, and logistic regression. Results: A total of 291 physicians completed the survey (222 primary care physicians, 33 pulmonologists, and 36 allergists) for a response rate of 46%. The allergists asked about tobacco cigarette use as frequently as did the pulmonologists and more than the primary care physicians (p < 0.001), but they rarely asked about EC use. The pulmonologists scored highest on self-reported knowledge on ECs, although all the groups answered <40% of the questions correctly. The allergists did not feel as comfortable about providing EC cessation counseling as did the pulmonologists and primary care physicians (p < 0.001). All three groups were equally unlikely to recommend ECs as a cessation tool for tobacco cigarette users. Conclusion: Allergists lacked knowledge and confidence in providing education and cessation counseling for EC users. As the number of patients who use these products continues to increase, there is an urgent need for all physicians to be comfortable and knowledgeable with counseling about ECs.

ABSTRACT Introduction: On Aug. 29, 2005, Hurricane Katrina made landfall along the Gulf Coast of the United States, resulting in the evacuation of more than 1.5 million people, including nearly 6000 physicians. This article examines the relocation patterns of physicians following the storm, determines the impact that the disaster had on their lives and practices, and identifies lessons learned. Methods: An Internet-based survey was conducted among licensed physicians reporting addresses within Federal Emergency Management Agency-designated disaster zones in Louisiana and Mississippi. Descriptive data analysis was used to describe respondent characteristics. Multivariate logistic regression was performed to identify the factors associated with physician nonreturn to original practice. For those remaining relocated out of state, bivariate analysis with x2 or Fisher exact test was used to determine factors associated with plans to return to original practice. Results: A total of 312 eligible responses were collected. Among disaster zone respondents, 85.6 percent lived in Louisiana and 14.4 percent resided in Mississippi before the hurricane struck. By spring 2006, 75.6 percent (n = 236) of the respondents had returned to their original homes, whereas 24.4 percent (n = 76) remained displaced. Factors associated with nonreturn to original employment included family or general medicine practice (OR 0.42, 95 percent CI 0.17–1.04; P = .059) and severe or complete damage to the workplace (OR 0.24, 95 percent CI 0.13–0.42; P &lt; .001). Conclusions: A sizeable proportion of physicians remain displaced after Hurricane Katrina, along with a lasting decrease in the number of physicians serving in the areas affected by the disaster. Programs designed to address identified physician needs in the aftermath of the storm may give confidence to displaced physicians to return.

Abstract Background According to recent projections, even 10% of Polish gross domestic product is contributed by Ukrainian immigrants. There is also a considerable number of Ukrainians continuing university education in Poland. The level of health literacy in Ukrainian society has not been studied so far. The aim of the study was the comparison of health literacy (HL) and e-health literacy (eHL) of young adult Ukrainian (UA) women with their Polish (PL) counterparts Methods A snowball technique was used to recruit a sample of UA women working or studying in Poland to the Internet-based survey. The questionnaire used in the study consisted of the 16-item European HL Survey questionnaire (HLS-EU-16), eHealth Literacy Scale (eHEALS), the set of the questions asking about health behaviours (HB), self-assessment of health status (HS) and items exploring sociodemographic variables. For comparison, the data of an age-matched sample of 100 respondents was extracted from the online survey performed in a representative sample of PL women. Results The mean age (standard deviation, SD) of 57 UA respondents was 20.23 (1.78) years and in Polish sample 20.25 (1.79). HL did not differ between both groups (11.06 (4.22) vs 11.44 (4.34), respectively, p = 0.53), but eHL was significantly lower in UA group (25.91 (5.36) vs 28.17 (5.37), U Mann-Whitney test, p = 0.01). Only 58.5% of UA respondents vs 80.5% of PL ones assessed their HS as at least good (Fisher exact test, p &lt; 0.001). The rates of active smoking (34.6% vs. 35.0%, p = 0.55), using e-cigarettes (35.3% vs 34.0%, p = 0.99), frequent alcohol consumption (26.9% vs. 20%, p = 0.41), and intensive physical activity (49.0% vs. 38.0%, p = 0.22) did not differ between study groups. Conclusions Young UA women show lower eHL than PL counterparts. Although HL and HB in both groups did not differ significantly, UA respondents have assessed their HS much lower than PL participants. Key messages E-health literacy and self-assessed health status were significantly lower among young Ukrainian than among Polish women. Both groups did not differ for health literacy and health behaviours.

Background:Systemic lupus erythematosus (SLE) has a significant genetic predisposition. Many genetic variants of susceptibility to SLE have been published and analyzed, but the clinical and functional significance of the various genotypes has not yet been clearly defined [1].Objectives:To estimate the association between some of non-HLA gene polymorphisms such as STAT4 rs7574865, RUNX1 rs9979383, IL6 rs1800795, IL6R rs2228145, IL6R rs4845618 and susceptibility to SLE in Belarusian population as well as some disease manifestations.Methods:We examined 383 healthy blood donors and 54 SLE patients (18-72 years old, median age 35) classified according to the 1997 American College of Rheumatology (ACR) revised classification criteria [2]. Deoxyribonucleic acid was extracted from peripheral blood samples by phenol-chloroform method. Genotyping was performed by real-time PCR with fluorescent probes. Differences of distribution of all the single nucleotide polymorphism (SNP) genotypes and their associations with secondary antiphospholipid syndrom (APS) and lupus arthritis were analyzed using Pearson χ2 (χ2) and two-way Fisher exact test (F, p2-t). Diagnostic odds ratio (dOR), likelihood ratio of positive (LR +) and negative (LR –) tests and corresponding 95% confidence intervals (CI) were also calculated.Results:We revealed significant difference in STAT4 rs7574865 genotypes in SLE patients and healthy donors (χ2=8,27, р=0,016) with significant increase of ТТ genotype frequency in SLE patients vs healthy donors (χ2=6.83 p=0.009; p2-t =0.020; dOR=3.78 (CI95% 1.36-10.55); LR+ =3.44 (CI95% 1.35-8.71); LR– =0.91 (CI95% 0.83-0.98)). Lupus arthritis was more common in risk TT-genotype SLE carriers than in other SLE patients (χ2=5.902 p=0.015; p2-t =0.027).We revealed significant increase of СТ genotype (RUNX1 rs9979383) in healthy donors vs SLE patients (χ2=4.14; p=0.042; dOR=0.53 (CI95% 0.29-0.98); LR+ =0.69 (CI95% 0.45-0.99); LR– =1.3 (CI95% 1.01-1,56)). Lupus arthritis was more common in SLE СТ-genotype carriers than in other SLE patients (χ2=4.66 p=0.031; p2-t =0.058).Significant differences in IL6 rs1800795, IL6R rs2228145 and IL6R rs4845618 genotypes distribution between studied groups were not found (χ2, p=0.427, p=0.559 and p=0.407, correspondingly) but GG-genotype (IL6 rs1800795) carriership in SLE patients was associated with increased APS frequency (χ2=4.45, p=0.035; dOR=0.19 (CI95% 0.04-0.9); LR+ =0.28 (CI95% 0.07-0.93); LR– =1.41 (CI95% 1.03-1.64).Conclusion:Our data suggest the susceptibility to SLE in ТТ genotype of STAT4 rs7574865 polymorphism, protective role of СТ genotype of RUNX1 rs9979383 for SLE and association between GG-genotype of IL6 rs1800795 and APS in SLE patients in Belarusian population. Lupus arthritis was associated with ТТ genotype of STAT4 rs7574865 and СТ genotype of RUNX1 rs9979383.References:[1]Chen L, Morris DL, Vyse TJ.

Polymorphisms in genes that control immune function and regulation may influence susceptibility to pulmonary tuberculosis (TB). In this study, 14 polymorphisms in 12 key genes involved in the immune response ( VDR, MR1, TLR1, TLR2, TLR10, SLC11A1, IL1B, IL10, IFNG, TNF, IRAK1, and FOXP3) were tested for their association with pulmonary TB in 271 patients with TB and 251 community-matched controls from the Republic of Moldova. In addition, gene–gene interactions involved in TB susceptibility were analyzed for a total of 43 genetic loci. Single nucleotide polymorphism (SNP) analysis revealed a nominal association between TNF rs1800629 and pulmonary TB (Fisher exact test P = 0.01843). In the pairwise interaction analysis, the combination of the genotypes TLR6 rs5743810 GA and TLR10 rs11096957 GT was significantly associated with an increased genetic risk of pulmonary TB (OR = 2.48, 95% CI = 1.62–3.85; Fisher exact test P value = 1.5 × 10−5, significant after Bonferroni correction). In conclusion, the TLR6 rs5743810 and TLR10 rs11096957 two-locus interaction confers a significantly higher risk for pulmonary TB; due to its high frequency in the population, this SNP combination may serve as a novel biomarker for predicting TB susceptibility.

A Prospective Study

Host genetic susceptibility is an important risk factor in infectious diseases. We explored the distribution of Q223R mutation in leptin receptor gene of amoebic liver abscess (ALA) patients of North India. A total of 55 ALA samples along with 102 controls were subjected to PCR-RFLP analysis. The frequency of allele “G” (coding for arginine) was in general high in Indian population irrespective of the disease. Our results of Fisher exact test shows that heterozygous mutant (QQ versus QR,P=0.049) and homozygous mutant (QQ versus RR,P=0.004) were significantly associated with amoebic liver abscess when compared with homozygous wild (QQ).
