Chagasic Megaesophagus

Abstract Background Chagasic megaesophagus (clinical manifestation of chagasic disease) has been reported as an etiological factor for squamous cell carcinoma of the esophagus, as well as the presence of human papillomavirus (HPV). Objective We accessed the prevalence of HPV DNA in a series of squamous cell carcinomas of the esophagus associated or not with the chagasic megaesophagus, and within samples of chagasic megaesophagus without cancer. Data obtained was further correlated to the pathological clinical data of affected individuals. Methods Retrospective study that used a total 92 samples tissue/biopsy specimens of formalin fixed and paraffin embedded tissues were retrospectively collected from the southeast region of Brazil from patients treated in three hospitals: Barretos Cancer Hospital, Barretos, São Paulo; Federal University of Triângulo Mineiro (UFTM), Uberaba, Minas Gerais; and São Paulo State University (UNESP), Botucatu, São Paulo. Cases were divided in three groups: i) 24 patients with chagasic megaesophagus associated with esophageal ESCC (CM/ESCC); ii) 37 patients with esophageal ESCC without chagasic megaesophagus (ESCC); iii) 31 patients with chagasic megaesophagus without esophageal ESCC (CM). Results We detected a higher prevalence of high-risk HPVs in patients from both CM (12/31, 38.8%) and CM/ESCC groups (8/24, 33.3%), as compared to individuals of the ESCC group (6/37, 16.3%), although data was not statistically significant. We further observed that HPV-16 was more prevalent in patients of the ESCC (4/9, 44.5%) and CM/ESCC groups (2/8, 25.0%). In addition, some of these samples presented infection by multiple HPV types. High-risk HPVs detected were HPV-31, 45, 51, 53, 56, 66, and 73, of which the majority was identified in patients from the CM group. Furthermore, low-risk HPV-11 and HPV-70 were identified in individuals from both ESCC and CM groups. Conclusion This is the first report regarding the presence of HPV DNA in megaesophagus associated with esophageal squamous cell carcinoma. In the present study, HPV infection appears to be directly related to the development of esophageal squamous cell carcinoma in patients with chagasic megaesophagus. Further studies are warrantee to confirm and better understand the role of oncogenic HPV persistent infection in these patients.

Chagasic Megaesophagus

<b><i>Background:</i></b> Chagasic megaesophagus (CM) as well as the presence of human papillomavirus (HPV) has been reported as etiological factors for esophageal squamous cell carcinoma (ESCC). <b><i>Objective:</i></b> We assessed the prevalence of HPV DNA in a series of ESCCs associated or not with CM. Data obtained were further correlated to the pathological and clinical data of affected individuals. <b><i>Methods:</i></b> A retrospective study was performed on 92 formalin-fixed and paraffin-embedded tissues collected from patients referred to 3 different hospitals in São Paulo, Brazil: Barretos Cancer Hospital, Barretos, São Paulo; Federal University of Triângulo Mineiro, Uberaba, Minas Gerais; and São Paulo State University, Botucatu, São Paulo. Cases were divided into 3 groups: (i) 24 patients with CM associated with ESCC (CM/ESCC); (ii) 37 patients with ESCC without CM (ESCC); and (iii) 31 patients with CM without ESCC (CM). Detection of HPV DNA was assessed in all samples by a genotyping assay combining multiplex polymerase chain reaction and bead-based Luminex technology. <b><i>Results:</i></b> We identified a high prevalence of high-risk HPV in patients in the CM group (12/31, 38.8%) and CM/ESCC (8/24, 33.3%), compared to individuals in the ESCC group (6/37, 16.3%). The individuals in the groups with cancer (ESCC and CM/ESCC) had a higher frequency of HPV-16 (4/9, 44.5% and 2/8, 25.0%). The other types of high-risk HPVs detected were HPV-31, 45, 51, 53, 56, 66, and 73. We also observed in some samples HPV coinfection by more than one viral type. Despite the high incidence of HPV, it did not show any association with the patient’s clinical-pathological and molecular (<i>TP53</i> mutation status) characteristics. <b><i>Conclusion:</i></b> This is the first report of the presence of HPV DNA in CM associated with ESCC. HPV infection was more presence in megaesophagus lesions. Further studies are needed to confirm and better understand the role of persistent HPV infection in patients with CM.

Abstract Background To explore the postoperative prognosis of esophageal squamous cell carcinoma (ESCC) patients with stage IB/IIA, using a prognostic score (PS). Methods Stage IB/IIA ESCC patients who underwent esophagectomy from 1999 to 2010 were included. We retrospectively recruited 153 patients and extracted their medical records. Moreover, we analyzed the programmed death ligand-1 (PD-L1) expression of their paraffin tissue. The cohort were randomly divided into a training group (N = 123) and a validation group (N = 30). We selected overall survival (OS) as observed endpoint. Prognostic factors with a multivariable two-sided P < 0.05 met standard of covariate inclusion. Results Univariable and multivariable analyses identified pTNM stage, the number of lymph nodes (NLNs) and PD-L1 expression as independent OS predictors. Primary prognostic score which comprised above three covariates adversely related with OS in two cohorts. PS discrimination of OS was comparable between the training and internal validation cohorts (C-index = 0.774 and 0.801, respectively). In addition, the PS system had an advantage over pTNM stage in the identification of high-risk patients (C-index = 0.774 vs. C-index = 0.570, P < 0.001). Based on PS cutoff, training and validation datasets generated low-risk and high-risk groups with different OS. Our three-factor PS predicted OS (low-risk subgroup vs. high-risk subgroup 60-month OS, 74% vs. 23% for training cohort and 83% vs. 45% for validation cohort). Conclusion Our study suggested a PS for significant clinical stratification of IB/IIA ESCC to screen out subgroups with poor prognosis.

Abstract Background No previous study has investigated the association between oolong tea consumption and esophageal squamous cell carcinoma (ESCC), we aim to elucidate the association between oolong tea consumption and ESCC and its joint effects with a novel composite index. Methods In a hospital-based case-control study, 646 cases of ESCC patients and 646 sex and age matched controls were recruited. A composite index was calculated to evaluate the role of demographic characteristics and life exposure factors in ESCC. Unconditional logistic regression was used to calculate the point estimates between oolong tea consumption and risk of ESCC. Results No statistically significant association was found between oolong tea consumption and ESCC (OR = 1.39, 95% CI: 0.94–2.05). However, drinking hot oolong tea associated with increased risk of ESCC (OR = 1.60, 95% Cl: 1.06–2.41). Furthermore, drinking hot oolong tea increased ESCC risk in the high-risk group (composite index> 0.55) (OR = 3.14, 95% CI: 1.93–5.11), but not in the low-risk group (composite index≤0.55) (OR = 1.16, 95% CI: 0.74–1.83). Drinking warm oolong tea did not influence the risk of ESCC. Conclusions No association between oolong tea consumption and risk of ESCC were found, however, drinking hot oolong tea significantly increased the risk of ESCC, especially in high-risk populations.
