- Human papillomavirus status and prognosis of oropharyngeal high-grade neuroendocrine carcinoma(2023) SOUSA, Luana G. de; NETO, Felippe Lazar; LAGO, Eduardo A. Dal; SIKORA, Andrew; HANNA, Ehab; MORENO, Amy; PHAN, Jack; GLISSON, Bonnie S.; BELL, Diana; FERRAROTTO, RenataBackground: The prognostic impact of human papillomavirus (HPV) infection or smoking on oropharyngeal high-grade neuroendocrine carcinoma (HG-NEC) is not established. Methods: Retrospective study with patients with oropharyngeal HG-NEC seen at MD Anderson Cancer Center from 1997 to 2020, and previously reported patients with oropharyngeal HG-NEC and known p16 and HPV status from the literature review. Survival was estimated with the Kaplan-Meier method, and survival differences assessed with the log-rank test and Cox proportional hazards models. Results: Thirty patients were included; most had a heavy (>= 10 pack-years) smoking history (52%), locoregional disease (stage III-IVB; 77%), and p16-positive tumor (92%). HPV was positive in 65% of tested samples (15/23). Of 24 patients treated with curative intent, the objective response rates was 90% (9/10) and 81% (17/21), respectively, for induction chemotherapy and definitive radiotherapy. During follow-up, 54% (13/24) recurred, mostly (11/13) at distant sites. Median overall survival (OS) was 46 months (95% CI, 14.3 -NA). OS was not associated with HPV status (HR 0.73, P = 0.6) or smoking (HR 1.16, P = 0.8). Among 63 patients with known HPV status after the literature review (19 HPV-and 44 HPV + ), HPV status remained unassociated with OS (P = 0.92). Conclusions: This is the largest retrospective cohort of oropharyngeal HG-NEC. Distant recurrence rate after curative treatment was high, suggesting that multimodality treatment including systemic therapy may benefit patients with locally advanced disease. HPV infection did not affect survival outcomes, therefore should not lead to therapy de-intensification for this histology.
conferenceObject Impact of readmission for patients with cancer in a public health system.(2022) HIDALGO FILHO, Cassio Murilo Trovo; LAZAR NETO, Felippe; ROCHA, Joao Wilson Da; BONADIO, Renata Colombo; HOFF, Paulo Marcelo- Predictors of in-hospital mortality after unplanned admissions among adults with cancer aged 80 years and older(2022) NETO, F.

conferenceObject Cost-effectiveness of novel systemic therapies for advanced breast cancer: Global representativeness and influence of funding(2023) LAZAR NETO, Felippe; MELO, Marina; HIDALGO FILHO, Cassio Murilo Trovo; MATHIAS, Maria Cecilia; TESTA, Laura; CAMPOLINA, Alessandro- Understanding urologic scientific publication patterns and general public interests on stone disease: lessons learned from big data platforms(2021) MARCHINI, Giovanni S.; FARIA, Kauy V. M.; NETO, Felippe L.; TORRICELLI, Fabio Cesar Miranda; DANILOVIC, Alexandre; VICENTINI, Fabio Carvalho; BATAGELLO, Carlos A.; SROUGI, Miguel; NAHAS, William C.; MAZZUCCHI, EduardoPurpose To analyse patterns of stone disease online information-seeking behaviours in the United States and to correlate with urological literature publication aspects. Methods To compare Relative Search Volume (RSV) among different twelve preselected urologic keywords we chose ""United States"" as country and ""01/01/2009-31/12/2018"" as time range on Google Trends (GT). We defined ""ureteroscopy"" as a reference and compared RSV against it for each term. RSV was adjusted and normalized in a scale 0-100. Trend presence was evaluated by Mann-Kendall Test and magnitude by Sen's Slope Estimator (SS). Weather influence on RSV was also investigated by comparison of the ten hottest versus ten coldest states. Pearson correlation analysis was performed between number of Pubmed publications and RSV for each term over time. Results We found an upward tendency (p 0.01) for most terms. Higher temporal trends were seen for ""kidney stone"" (SS = 0.36), ""kidney pain"" (SS = 0.39) and ""tamsulosin"" (SS = 0.21). Technical treatment terms had little search volumes and no increasing trend. States with hotter weather showed higher mean RSV for ""kidney stone"" than colder ones. There was little correlation between GT and Pubmed for most terms, with the exception of ""kidney stone"" (R = 0.89; p 0.01), ""URS"" (R = 0.81; p 0.01), and ""laser lithotripsy"" (R = 0.74; p = 0.01). Conclusion There was a significant increase in online search for medical information related to stone disease. Citizens tend to look for generic terms related to symptoms or the disease itself. States with hotter weather show higher RSV than colder states. There is a discrepancy between public and medical community medical terms.
- Prevalence and predictors of overweight and obesity in Brazilian immigrants in Massachusetts(2020) KLABUNDE, Rachel A.; NETO, Felippe Lazar; LOUZADA, Andressa; MOURA, Ricardo Fae de; CALIXTO, Fernando Morelli; DANAEI, Goodarz; CASTRO, Marcia C.BackgroundOverweight and obesity are important risk factors for chronic non-communicable diseases, and their prevalence is on the rise worldwide. This study seeks to describe the prevalence and predictors of overweight and obesity in Brazilian immigrants living in Massachusetts, United States of America (USA).MethodsModeled after a survey on behavioral risk factors for chronic disease conducted annually in Brazil (Vigilancia de Fatores de Risco e ProtecAo para Doencas Cronicas por Inquerito Telefonico: Vigitel), Brazilian immigrants aged 18+ (n=361) were surveyed between December 2013 and March 2014. Information was obtained from consenting participants regarding their demographic characteristics, physical activity, dietary and lifestyle habits, and other behavioral risk factors. Weight status was estimated from body mass index (BMI), calculated from self-reported height and weight data. Participants were categorized as overweight/obese if their BMI was >= 25; overweight and obese categories were combined to ensure appropriate sample size. Prevalence of overweight/obesity was estimated using STATA, and significant predictors were identified via multi-variable logistic regression. Odds ratio (OR), 95% confidence intervals (95% CI) and p-values were determined.ResultsThe overall prevalence of overweight/obesity in the sample was 47.6%. Significant predictors of overweight and obesity were gender (men OR 2.30, 95% CI: 1.10, 3.78; women are comparison group), working in the 3months prior to the survey (OR 2.90, 95% CI: 1.01, 8.30), and longer duration living in the USA (OR per additional year 1.06, 95% CI: 1.02, 1.11). Significant dietary predictors of overweight/obesity included 5 or more days per week of consumption of red meat (OR red meat 3.70, 95% CI: 1.47, 9.26) or of sweetened beverages, like soft drinks also known as soda (OR soda 2.40, 95% CI: 1.00, 5.78) compared with less frequent consumption of these foods.ConclusionsThis study suggests that long duration of time lived in the USA increases odds of overweight and obesity for Brazilian immigrants living in Massachusetts. Efforts to curb increases in overweight and obesity in this population should focus not only on the men and those who work but also the women. Possible intervention measures should target soda (soft drink) and red meat consumption in Brazilian immigrants.
- External validity of type 2 diabetes clinical trials on cardiovascular outcomes for a multimorbid population(2021) LAZAR NETO, Felippe; MENDES, Thiago Bosco; MATOS, Paulo Marcelo Pontes Gomes; OLIVEIRA, Julio Cesar de; FAVARATO, Maria Helena Sampaio; LIN, Chin An; MARTINS, Milton ArrudaAim: To investigate the external validity of recent antihyperglycaemic trials evaluating cardiovascular outcomes in a multimorbid population. Materials and Methods: Selection criteria of 15 randomized controlled trials from the 2020 American Diabetes Association Standard of Care statement were applied in a stepwise manner to tertiary care patients with type 2 diabetes. Primary outcomes were the number of patients eligible per individual trial and for the aggregate of trials. Secondary outcomes included patient predictors of trial eligibility. Results: Of 1059 patients, the mean (SD) age was 66 (10.74) years, the median (IQR) Charlson index was 2 (2, 3) and 458 (43%) had documented cardiovascular disease. The median (IQR) number of patients included in individual trials was 263 (174.25-308.75) and 795 (75.1%) of them were eligible for at least one trial. Among those 264 ineligible, 127 (48.1%) had an HbA1c level of 7% or less and no cardiovascular disease; 53.5% and 34.4% of the patients were eligible for two and three different classes of drugs, respectively. The strongest predictor of trial eligibility was cardiovascular disease (risk ratio 2.17, 95% CI 2.01-2.35). Conclusions: A considerable proportion of multimorbid patients would be eligible for recent antihyperglycaemic trials. This positive finding can be attributed to development guidance in diabetes trials and the different approach we took, in which we evaluated inclusion by trials as an aggregate.
- Long-term outcomes of neoadjuvant immunotherapy plus chemotherapy in patients with early-stage triple-negative breast cancer: an extracted individual patient data and trial-level meta-analysis(2024) CUNHA, Mateus Trinconi; GOUVEIA, Mariana Carvalho; LAZAR NETO, Felippe; TESTA, Laura; HOFF, Paulo Marcelo; AZAMBUJA, Evandro de; BONADIO, Renata ColomboBackground: Neoadjuvant immunotherapy (nIO) has emerged as a treatment option for stage II-III triple-negative breast cancer (TNBC). While randomised clinical trials (RCTs) demonstrated pathological complete response rate benefit to nIO added to chemotherapy, additional data on long-term outcomes is warranted. We performed this analysis to evaluate long-term efficacy outcomes of nIO in TNBC.Methods: We searched databases for RCTs evaluating nIO in early-stage TNBC. A meta-analysis of extracted individual patient data (EIPD) was performed to evaluate EFS and OS, with data from reported Kaplan-Meier plots. Additionally, we conducted a trial-level meta-analysis using fixed and random effects models.Results: The literature search resulted in four included RCTs with available EFS or OS (KEYNOTE-522, IMpassion031, I-SPY2 and GeparNuevo). EIPD showed that the addition of nIO to chemotherapy provides statistically significant benefits in EFS (HR 0.62, 0.50-0.76; p < 0.001) and OS (HR 0.62, 0.46-0.82, p < 0.001). Number needed to treat to avoid one EFS or OS event in 4 years was 9 and 14, respectively. Trial-level meta-analysis yielded similar results (EFS: HR 0.64, 0.51-0.79; OS: 0.57, 0.37-0.89).Conclusions: Results show that nIO combined with chemotherapy can provide significant EFS and OS benefits, supporting its use as standard treatment for early-stage TNBC.
- Comparative assessment of mortality risk factors between admission and follow-up models among patients hospitalized with COVID-19(2021) LAZAR NETO, Felippe; SALZSTEIN, Guilherme A.; CORTEZ, Andre L.; BASTOS, Thais L.; BAPTISTA, Fabiola V. D.; MOREIRA, Joanne A.; LAUTERBACH, Gerhard P.; OLIVEIRA, Julio Cesar de; ASSIS, Fabio C. de; AGUIAR, Marilia R. A.; DEUS, Aline A. de; DIAS, Marcos Felipe D. S.; SOUSA, Felipe C. B.; DUAILIBI, Daniel F.; KONDO, Rodrigo H.; MORAES, Augusto Cesar F. de; MARTINS, Milton A.Objectives: This study aimed to compare differences in mortality risk factors between admission and follow-up incorporated models. Methods: A retrospective cohort study of 524 patients with confirmed COVID-19 infection admitted to a tertiary medical center in S?o Paulo, Brazil from 13 March to 30 April 2020. Data were collected on admission, and the third, eighth and fourteenth days of hospitalization. The hazard ratio (HR) was calculated and 28-day in-hospital mortality risk factors were compared between admission and followup models using a time-dependent Cox regression model. Results: Of 524 patients, 50.4% needed mechanical ventilation. The 28-day mortality rate was 32.8%. Compared with follow-up, admission models under-estimated the mortality HR for peripheral oxygen saturation 92% (1.21 versus 2.09), heart rate 100 bpm (1.19 versus 2.04), respiratory rate >24/min (1.01 versus 1.82) and mechanical ventilation (1.92 versus 12.93). Low oxygen saturation, higher oxygen support and more biomarkers?including lactate dehydrogenase, C-reactive protein, neutrophillymphocyte ratio, and urea remained associated with mortality after adjustment for clinical factors at follow-up compared with only urea and oxygen support at admission. Conclusions: The inclusion of follow-up measurements changed mortality hazards of clinical signs and biomarkers. Low oxygen saturation, higher oxygen support, lactate dehydrogenase, C-reactive protein, neutrophil-lymphocyte ratio, and urea could help with prognosis of patients during follow-up. ? 2021 The Authors.
- Mortality and other outcomes of patients with coronavirus disease pneumonia admitted to the emergency department: A prospective observational Brazilian study(2021) BRANDAO NETO, Rodrigo A.; MARCHINI, Julio F.; MARINO, Lucas O.; ALENCAR, Julio C. G.; LAZAR NETO, Felippe; RIBEIRO, Sabrina; SALVETTI, Fernando V.; RAHHAL, Hassan; GOMEZ, Luz Marina Gomez; BUENO, Caue G.; FARIA, Carine C.; CUNHA, Victor P. da; PADRAO, Eduardo; VELASCO, Irineu T.; SOUZA, Heraldo Possolo deBackground The first cases of coronavirus disease (COVID-19) in Brazil were diagnosed in February 2020. Our Emergency Department (ED) was designated as a COVID-19 exclusive service. We report our first 500 confirmed COVID-19 pneumonia patients. Methods From 14 March to 16 May 2020, we enrolled all patients admitted to our ED that had a diagnosis of COVID-19 pneumonia. Infection was confirmed via nasopharyngeal swabs or tracheal aspirate PCR. The outcomes included hospital discharge, invasive mechanical ventilation, and in-hospital death, among others. Results From 2219 patients received in the ED, we included 506 with confirmed COVID-19 pneumonia. We found that 333 patients were discharged home (65.9%), 153 died (30.2%), and 20 (3.9%) remained in the hospital. A total of 300 patients (59.3%) required ICU admission, and 227 (44.9%) needed invasive ventilation. The multivariate analysis found age, number of comorbidities, extension of ground glass opacities on chest CT and troponin with a direct relationship with all-cause mortality, whereas dysgeusia, use of angiotensin converting enzyme inhibitor or angiotensin-ii receptor blocker and number of lymphocytes with an inverse relationship with all-cause mortality Conclusions This was a sample of severe patients with COVID-19, with 59.2% admitted to the ICU and 41.5% requiring mechanical ventilator support. We were able to ascertain the outcome in majority (96%) of patients. While the overall mortality was 30.2%, mortality for intubated patients was 55.9%. Multivariate analysis agreed with data found in other studies although the use of angiotensin converting enzyme inhibitor or angiotensin-ii receptor blocker as a protective factor could be promising but would need further studies.
