- Induction Chemotherapy for Locally Advanced Esophageal Cancer(2020) HARADA, Guilherme; BONADIO, Renata Rodrigues da Cunha Colombo; ARAUJO, Frederico Cantarino Cordeiro de; VICTOR, Carolina Ribeiro; SALLUM, Rubens Antonio Aissar; RIBEIRO JUNIOR, Ulysses; CECCONELLO, Ivan; TAKEDA, Flavio Roberto; CASTRIA, Tiago Biachi deBackground Concurrent chemoradiotherapy followed by surgery is the standard treatment for locally advanced esophageal cancer (EC), and the role of induction chemotherapy (IC) remains unclear. We aimed to study if the addition of IC to standard treatment increases the rate of pathologic complete response (pCR). Methods We assembled a retrospective analysis of patients (pts) diagnosed with locally advanced EC and treated with preoperative chemoradiotherapy followed by esophagectomy (CRT+S), preceded or not by IC, between 2009 and 2017. Patients' characteristics, tumor variables, and treatment outcomes were evaluated. The Kaplan-Meier method was used to estimate overall survival and the Cox proportional hazard model to evaluate prognostic factors. Results One hundred and three patients were studied, with a median age of 62 years (range 37-84). Seventy-five patients (73%) were male, 67 (65%) had squamous cell carcinoma, and 31 (30%) had adenocarcinoma. Forty-three patients (41.7%) received IC followed by CRT+S (IC+CRT+S). The most frequent IC consisted of paclitaxel and platinum chemotherapy (90%), and the median number of cycles was 2. All patients received CRT+S. Concurrent chemotherapy was a combination of paclitaxel and platinum in 94 patients (91%). There was no statistically significant difference in pCR between the IC group and the standard CRT+S group. The pCR was 41.9% and 46.7% in the IC+CRT+S and CRT+S groups (p = 0.628), respectively. In the multivariate analysis, pCR was an independent prognostic factor for time to treatment failure (TTF) (HR 0.35, p = 0.021), but not for overall survival (OS) (p = 0.863). The factor that significantly affected OS in the multivariate analysis was positive lymph node (HR 5.9, 95%, p = 0.026). Conclusions Our data suggest that the addition of IC to standard CRT + S does not increase the pCR rate in locally advanced EC. No difference in OS was observed between pts. that received or not IC. Regardless of the treatment received, pts. achieving a pCR presented improved TTF.
- Predictive factors of recurrence in adenocarcinoma of the esophagogastric junction in the multimodal era(2021) TAKEDA, Flavio Roberto; RAMOS, Marcus Fernando Kodama Pertille; PEREIRA, Marina Alessandra; MUNIZ, Renan Rosetti; TUSTUMI, Francisco; CASTRIA, Tiago Biachi de; SALLUM, Rubens Antonio Aissar; ZILBERSTEIN, Bruno; RIBEIRO JUNIOR, Ulysses; CECCONELLO, IvanIntroduction: Adenocarcinoma of the esophagogastric junction (AEGJ) represents a poor prognostic tumor. We evaluated the recurrence pattern and risk factors associated with recurrence in patients undergoing surgical resection by AEJG. Methods: Recurrences were categorized as locoregional, peritoneal, or distant. These three recurrence groups and a non-recurrence group were compared, and overall survival (OS) and disease-free survival (DFS) for each one was obtained. Results: We analyzed 188 patients with curative surgical treatment. Recurrence was observed in 72 (38.3%) patients. Locoregional recurrence was observed in 17 (23.6%); 20 (27.8%) peritoneal recurrence and 35 (48.6%) distant metastasis. DFS was 9, 5, and 8 months, and OS was 21.8, 13.2, and 20.8, respectively. Tumors larger than 5 cm are risk factors for peritoneal recurrence (OR:2.88, p = 0.012). Positive lymph nodes were related to distant metastasis (OR:9.15, p = 0.040), and lymphatic invasion for locoregional recurrence (OR:3.81, p = 0.028). Conclusion: AEGJ is associated with high rates of early recurrence.
- Prognostic value of F-18-fluorodeoxyglucose PET/computed tomography metabolic parameters measured in the primary tumor and suspicious lymph nodes before neoadjuvant therapy in patients with esophageal carcinoma(2021) TUSTUMI, Francisco; DUARTE, Paulo Schiavom; ALBENDA, David Gutierrez; TAKEDA, Flavio Roberto; SALLUM, Rubens Antonio Aissar; RIBEIRO JUNIOR, Ulysses; BUCHPIGUEL, Carlos Alberto; CECCONELLO, IvanBackground F-18-fluorodeoxyglucose PET/computed tomography (F-18-FDG PET/CT) metabolic parameters are prognostic indicators in several neoplasms. This study aimed to evaluate the prognostic value of the maximum and average standardized uptake value (SUVmax and SUVavg), metabolic tumor value (MTV), and total lesion glycolysis (TLG) measured in the primary tumor and suspicious lymph nodes preneoadjuvant therapy in patients submitted to surgical resection for esophageal cancer. Methods A cohort of 113 patients with esophageal cancer who performed F-18-FDG PET/CT preneoadjuvant therapy was assessed. The association of the SUV, MTV, and TLG measured in the primary tumor and in the suspicious lymph nodes with the overall survival was assessed. It was also analyzed other potentially confounding variables such as age, sex, clinical stage, and histologic subtype. The analyses were performed using Kaplan-Meier curve, log-rank test, and Cox regression. Results The univariate analyses showed that the MTV and TLG in the primary tumor, the SUV in the suspicious lymph nodes, the age, the histologic subtype, and the clinical stage were associated with survival after surgery (P <= 0.05). In the Cox regression multivariate analyses, all variables identified in the univariate analyses but the clinical stage were associated with survival after surgery (P <= 0.05). Conclusion In esophageal cancer patients, some of the F-18-FDG PET/CT metabolic parameters measured in the primary tumor and in the suspicious lymph nodes before the neoadjuvant therapy are independent indicators of overall survival and appear to be more important than the clinical stage in the prognostic definition of this group of patients.
- LYMPHOCYTE COUNT AND PLATELET VOLUME PREDICTS POSTOPERATIVE COMPLICATIONS IN ESOPHAGECTOMY FOR CANCER: A COHORT STUDY(2019) TUSTUMI, Francisco; TAKEDA, Flávio Roberto; BRANDÃO, Antonio Adolfo Guerra Soares; SALLUM, Rubens Antonio Aissar; RIBEIRO JUNIOR, Ulysses; CECCONELLO, IvanABSTRACT BACKGROUND: Biomarkers from routine complete blood count are known predictive factors of long-term outcomes in cancer patients. The value of these biomarkers in the setting of trimodal therapy for esophageal cancer in predicting early postoperative outcomes is not studied. OBJECTIVE: The present study evaluated the value of cellular blood components changes during neoadjuvant chemoradiotherapy followed by curative intent esophagectomy for cancer in predicting postoperative mortality and morbidity. METHODS: A cohort of 149 consecutive patients that underwent chemoradiotherapy using platinum- and taxane-based regimens followed by esophagectomy was analyzed. Cellular components of blood collected before neoadjuvant therapy (period A) and before surgery (period B) were assessed for postoperative mortality and complications. Univariate and multivariate Cox regression models were applied to evaluate the independent prognostic significance of blood count variables. RESULTS: Postoperative morbidity was present in 46% of the patients. On multiple regression analysis platelet volume (B) (OR: 1.53; 95% CI: 1.2-2.33) was an independent predictor of general complications. Severe postoperative surgical complications were present in 17% of the patients. On multiple regression analysis, lymphocyte decrease between B-A periods (OR: 0.992; 95% CI: 0.990-0.997) was related to higher risk for severe complications. Cervical anastomotic leakage was present in 25.6% of the patients. On univariate analysis eosinophil count in A and B periods was related to cervical anastomotic leakage. For this outcome, multivariate joint model could not identify independent risk variables of cellular components of blood. The 30-day mortality rate was 7.4%. On univariate analysis, platelet count in period B was associated to higher risk for mortality. The multivariate joint model could not accurately predict mortality due to the few number of patients in the mortality group. CONCLUSION: This is the first study to assess the relationship between peripheral blood count variables changes during neoadjuvant chemoradiotherapy using a platinum- and taxane-based regimen followed by curative intent esophagectomy for cancer in predicting postoperative complications. The platelet volume prior to surgery is related to postoperative complications and the lymphocyte count change prior to surgery predicts severe postoperative complications in the setting of trimodal therapy for esophageal cancer.
- ESOPHAGEAL CARCINOMA: IS SQUAMOUS CELL CARCINOMA DIFFERENT DISEASE COMPARED TO ADENOCARCINOMA? A transversal study in a quaternary high volume hospital in Brazil(2016) TUSTUMI, Francisco; TAKEDA, Flavio Roberto; KIMURA, Cintia Mayumi Sakurai; SALLUM, Rubens Antônio Aissar; RIBEIRO JUNIOR, Ulysses; CECCONELLO, IvanABSTRACT Background Esophageal cancer is one of the leading causes of mortality among the neoplasms that affect the gastrointestinal tract. There are several factors that contribute for development of an epidemiological esophageal cancer profile in a population. Objective This study aims to describe both clinically and epidemiologically the population of patients with diagnosis of esophageal cancer treated in a quaternary attention institute for cancer from January, 2009 to December, 2011, in Sao Paulo, Brazil. Methods The charts of all patients diagnosed with esophageal cancer from January, 2009, to December, 2011, in a Sao Paulo (Brazil) quaternary oncology institute were retrospectively reviewed. Results Squamous cell cancer made up to 80% of the cases of esophageal cancer. Average age at diagnosis was 60.66 years old for esophageal adenocarcinoma and 62 for squamous cell cancer, average time from the beginning of symptoms to the diagnosis was 3.52 months for esophageal adenocarcinoma and 4.2 months for squamous cell cancer. Average time for initiating treatment when esophageal cancer is diagnosed was 4 months for esophageal adenocarcinoma and 4.42 months for squamous cell cancer. There was a clear association between squamous cell cancer and head and neck cancers, as well as certain habits, such as smoking and alcoholism, while adenocarcinoma cancer showed more association with gastric cancer and gastroesophageal reflux disease. Tumoral bleeding and pneumonia were the main causes of death. No difference in survival rate was noted between the two groups. Conclusion Adenocarcinoma and squamous cell carcinoma are different diseases, but both are diagnosed in advanced stages in Brazil, compromising the patients' possibilities of cure.
- THYLENETETRAHYDROFOLATE REDUCTASE GENE POLYMORPHISMS AND SUSCEPTIBILITY TO ESOPHAGEAL CANCER: A CASE-CONTROL STUDY(2022) ZAIDAN, Evelise Pelegrinelli; TOMITAO, Michele Tatiana Pereira; PEREIRA, Marina Alessandra; KUBRUSLY, Marcia Saldanha; SAFATLE-RIBEIRO, Adriana Vaz; TAKEDA, Flavio Roberto; CECCONELLO, Ivan; RIBEIRO JUNIOR, UlyssesBACKGROUND: The enzyme methylenetetrahydrofolate reductase is engaged in DNA synthesis through folate metabolism. Inhibiting the activity of this enzyme increases the susceptibility to mutations, and damage and aberrant DNA methylation, which alters the gene expression of tumor suppressors and proto-oncogenes, potential risk factors for esophageal cancer. AIMS: This study aimed to investigate the association between methylenetetrahydrofolate reductase 677C > T and methylenetetrahydrofolate reductase 1298A > C polymorphisms and susceptibility to esophageal cancer, by assessing the distribution of genotypes and haplotypes between cases and controls, as well as to investigate the association of polymorphisms with clinical and epidemiological characteristics and survival. METHODS: A total of 109 esophageal cancer patients who underwent esophagectomy were evaluated, while 102 subjects constitute the control group. Genomic DNA was isolated from the peripheral blood buffy coat followed by amplification by polymerase chain reaction and real-time analysis. Logistic regression was used to assess associations between polymorphisms and the risk of developing esophageal cancer. RESULTS: There was no association for methylenetetrahydrofolate reductase 677C > T and methylenetetrahydrofolate reductase 1298A > C polymorphisms and haplotypes, with esophageal cancer susceptibility. Esophageal cancer patients carrying methylenetetrahydrofolate reductase 677TT polymorphism had higher risk of death from the disease. For polymorphic homozygote TT genotype, the risk of death significantly increased compared to wild-type genotype methylenetetrahydrofolate reductase 677CC (reference) cases (p=0.045; RR=2.22, 95%CI 1.02-4.83). CONCLUSIONS: There was no association between methylenetetrahydrofolate reductase 677C > T and methylenetetrahydrofolate reductase 1298A > C polymorphisms and esophageal cancer susceptibility risk. Polymorphic homozygote genotype methylenetetrahydrofolate reductase 677TT was associated with higher risk of death after surgical treatment for esophageal cancer.
- Prognostic Value of Tumor Regression Grade Based on Ryan Score in Squamous Cell Carcinoma and Adenocarcinoma of Esophagus(2020) TAKEDA, Flavio Roberto; TUSTUMI, Francisco; OBREGON, Carlos de Almeida; YOGOLARE, Gustavo Goncalves; NAVARRO, Yasmin Peres; SEGATELLI, Vanderlei; SALLUM, Rubens Antonio Aissar; RIBEIRO JUNIOR, Ulysses; CECCONELLO, IvanPurposes Tumor regression grade (TRG) of the primary tumor after neoadjuvant therapy is one of the most sensitive prognostic factors among patients with locally advanced esophageal cancer, although no TRG system is fully accepted. The Ryan score was proposed in 2005 to evaluate TRG in rectal cancer and could be adaptable for pathological evaluation of esophageal cancer. The objective of this study is to evaluate the prognostic value of the Ryan score for esophageal cancer in the setting of trimodal therapy. Methods We performed a retrospective cohort study in which patients with locally advanced esophageal cancer, submitted to neoadjuvant therapy followed by surgical resection, were selected. One hundred thirty-four patients were selected. All tissue specimens were assessed as per the TRG system proposed by Ryan et al. Survival curves were assessed by the Kaplan-Meier method and log-rank test. Chi-square test or likelihood-ratio test was used for absolute and relative variables. Kruskal-Wallis and analysis of variance tests were used to assess significant differences on a continuous dependent variable by a categorical independent variable. Results Of the 134 included patients, 94 (70.1%) had squamous cell carcinoma, and 40 (29.9%) adenocarcinoma. Ryan score was correlated with histological type (p < 0.001), and clinical (p = 0.044) and pathological (p < 0.001) staging. Mean follow-up was 31.1 months. Multivariate analysis showed that Ryan score can safely predict survival, and systemic and lymphatic recurrence (p < 0.05). Conclusions Ryan score is an effective system to evaluate TRG and can predict risk for lymph node or distant metastasis, overall survival, and disease-free survival.
- Transhiatal laparoscopic esophagectomy with extended lymphadenectomy guided by green-indocyanine imaging for adenocarcinoma of the esophagogastric junction(2020) TAKEDA, Flavio Roberto; RIBEIRO JUNIOR, Ulysses; SALLUM, Rubens Antonio Aissar; CECCONELLO, IvanIntroduction: Surgical treatment for adenocarcinoma of the esophagogastric junction (AEGJ) has been long-established, from resection margins to the extension of lymphadenectomy [1,2,4]. The addition of cyanine dye, namely indocyanine green (ICG), to identify suspicious lymph nodes (LN) and evaluate organ vascularization may improve results and outcomes [3]. Video: A 58-year-old female patient with Siewert type II AEGJ was administered mFLOX neoadjuvant treatment. After three cycles, she underwent surgical treatment. The day before surgery, an upper endoscopy was performed to inject 0.2 ml ICG 0.5 cm from the proximal and distal tumor margins. The patient underwent laparoscopic transhiatal esophagectomy with extended lymphadenectomy due to a 4 cm distal esophagus compromised margin. We describe the primary steps of the procedure and demonstrate the role of the ICG in the lymphadenectomy. Results: Surgery was carried out lapamscopically with a cervical approach (McKeown access), and posterior mediastinal gastric tube reconstruction and cervical gastroplasty were performed. During the standard lymphadenectomy, we observed an ICG-positive LN in station 10, which was found positive in the subsequent pathology examination. After these findings, we performed an extended lymphadenectomy through the splenic hilum. The final pathologic assessment was T3N2 (two perigastric and one positive LN at station 10 among 60 retrieved LN). The operative time was 360 min. The patient started a liquid diet on the seventh postoperative day, and she was discharged on the tenth postoperative day. Conclusions: ICG may be helpful to guide both extended lymphadenectomy and distal margin evaluation in transhiatal lapamscopic esophagectomy.
- CHARACTERIZATION OF THE PSYCHOLOGICAL TYPOLOGY IN ESOPHAGEAL CANCER PATIENTS(2022) PINTO, Stela Duarte; RODRIGUEZ, Lorgio Henrique Diaz; TAKEDA, Flavio Roberto; TACCONI, Marcos Roberto; SALLUM, Rubens Antonio Aissar; CECCONELLO, Ivan; RIBEIRO JUNIOR, UlyssesBackground: Esophageal cancer is an environment-related disease, and the most important risk factors are alcohol intake and smoking, in addition to gastroesophageal reflux in obese patients. The characterization of the patients' personality can contribute to the perception of how everyone adapts to the social environment and what relationship one can establish with themselves and with others.Aim: The aim of this study was to identify the psychological typology in patients with esophageal cancer.Methods: The psychological typology of patients was defined using the Typological Assessment Questionnaire. In addition, the aspects of psychological assessment were studied to access the particularities of each patient, especially their reaction to the diagnosis and the meaning attributed to the disease.Results: A total of 90 patients with esophageal cancer, aged over 18 years, who completed high school, and were interviewed at the first medical appointment, were included. The introverted attitude was predominant (83.33%). The most common psychological type was introverted sensation, with feeling as a secondary function (43.3%), and the second most frequent was introverted feeling, with sensation as a secondary function (24.4%). From this psychological assessment, a variety of defensive mechanisms were found to minimize distress. Most patients made use of adaptive defenses in the face of the illness process.Conclusion: The identification of the psychological typology allows the most effective assistance in directing the peculiar needs of each patient. In addition, it contributes to the care team to individualize treatments based on specific psychological characteristics.
