RESUMO

Background: Tyrosine kinase inhibitors have been used to treat hepatocellular carcinoma (HCC), but the outcomes of patients under treatment vary. Since the roles of clinicopathological aspects and markers of chronic inflammation/immune homeostasis in the outcome of HCC patients treated with sorafenib are still unclear, these were the aims of this study. Methods: Patients with alcohol-induced and/or hepatitis C virus (HCV)-induced HCC (n = 182) uniformly treated with sorafenib were included in the study. Baseline clinicopathological aspects of patients were computed from the medical records. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic inflammation response index (SIRI), and systemic immune-inflammation index (SII) were obtained from the hematological exam performed before the administration of sorafenib. Overall survival (OS) was analyzed using Kaplan-Meier probabilities, log-rank test, and univariate and multivariate Cox proportional hazard ratio (HR) analyses. Results: In multivariate analysis, alpha-foetoprotein (AFP) level and Child-Pugh score were predictors of OS. Patients with AFP levels higher than 157 ng/mL and Child-Pugh B or C had 1.40 (95% confidence interval (CI): 1.03 - 1.91, P = 0.03) and 1.64 (95% CI: 1.07 - 2.52, P = 0.02) more chances of evolving to death than the remaining patients, respectively. NLR, PLR, LMR, SIRI, and SII did not alter the OS of HCC patients. Conclusions: AFP level and Child-Pugh score act as independent prognostic factors in patients with alcohol and/or HCV-induced HCC treated with sorafenib, but markers of chronic inflammation/immune homeostasis seem not to alter the outcome of patients with HCC induced by alcohol and/or HCV.

RESUMO

BACKGROUND: Since failure in recognition of abnormal cells by the immune system has an important role in bladder cancer development and progression, this study aimed to evaluate whether PD1 (c.627+252C>T) and PD1.5 (c.804C>T) single-nucleotide variants (SNVs) in PDCD1 gene, enrolled in modulation of T lymphocyte activity, influence risk, clinicopathological aspects, and outcome of non-muscle-invasive bladder cancer (NMIBC) patients. MATERIAL AND METHODS: DNA genotyping by real-time polymerase chain reaction was offered to 160 non muscle invasive bladder cancer (NMIBC) patients and 250 controls. One hundred and twenty-seven patients treated with bladder transurethral resection and intravesical bacillus Calmette-Guérin were enrolled in survival analyses. RESULTS: Individuals with PD1.5 CC genotype had 2.3-fold increased risk of developing NMIBC. Similar genotype and haplotype frequencies were seen in patients stratified by clinicopathological aspects. Patients with T allele, CT or TT plus CT or TT genotype and TT haplotype of PD1 and PD1.5 SNVs had up to 4.0-times greater chances of presenting NMIBC relapse and death by any cause than the remaining patients, but analysis of NMIBC specific survival was not possible in study due to the small number of patients evolving to death during follow up. CONCLUSIONS: Our data presented for the first time, preliminary evidence that inherited abnormality in regulation of T lymphocyte activity alters NMIBC risk.

RESUMO

BACKGROUND AND AIMS: An association between non-alcoholic fatty liver disease (NAFLD) and pancreatic ductal adenocarcinoma (PDAC) has been previously suggested. This study aims at investigating this association and at identifying potential links between variables of the NAFLD spectrum and PDAC. METHODS: A cross-sectional case-matched analytical and comparative study was carried out to analyze patients undergoing surgical resection of PDAC and compare them to a control group of individuals undergoing cholecystectomy at a public tertiary teaching hospital, matched by sex, age and BMI. Hepatic histopathological examinations were compared between cases and controls. RESULTS: Of 56 individuals, 36 were male (64.3%) and the median age was 61.5 years old (interquartile range: 57.5 - 70). The participants' median BMI was 24.3 kg/m2 (interquartile range: 22.1-26.2 kg/m2). Microvesicular steatosis (p=0.04), hepatocellular ballooning (p=0.02), fibrosis (p=0.0003) and steatohepatitis (p=0.03) were significantly more frequent in the group of cases. Odds ratios for hepatocellular ballooning (6.2; 95%CI: 1.2-31.8; p=0.03), fibrosis (9.3; 95%CI: 2.5-34.1; p=0.0008) and steatohepatitis (3.9; 95%CI: 1.1-14.3; p=0.04) were statistically significant in relation to the PDAC prevalence. CONCLUSIONS: Significant associations were identified between histopathological aspects of NAFLD (microvesicular steatosis, hepatocellular ballooning, fibrosis, and steatohepatitis) and PDAC.

RESUMO

PURPOSE: International guideline recommendations may not always be extrapolated to developing countries where access to resources is limited. In metastatic castration-sensitive prostate cancer (mCSPC), there have been successful drug and imaging advancements that were addressed in the Prostate Cancer Consensus Conference for Developing Countries for best-practice and limited-resource scenarios. METHODS: A total of 24 out of 300 questions addressed staging, treatment, and follow-up for patients with mCSPC both in best-practice settings and resource-limited settings. Responses were compiled and presented in percentage of clinicians supporting each response. Questions had 4-8 options for response. RESULTS: Recommendations for staging in mCSPC were split but there was consensus that chest x-ray, abdominal and pelvic computed tomography, and bone scan should be used where resources are limited. In both de novo and relapsed low-volume mCSPC, orchiectomy alone in limited resources was favored and in relapsed high-volume disease, androgen deprivation therapy plus docetaxel in limited resources and androgen deprivation therapy plus abiraterone in high-resource settings were consensus. A 3-weekly regimen of docetaxel was consensus among voters. When using abiraterone, a regimen of 1,000 mg plus prednisone 5 mg/d is optimal, but in limited-resource settings, half the panel agreed that abiraterone 250 mg with fatty foods plus prednisone 5 mg/d is acceptable. The panel recommended against the use of osteoclast-targeted therapy to prevent osseous complications. There was consensus that monitoring of patients undergoing systemic treatment should only be conducted in case of prostate-specific antigen elevation or progression-suggestive symptoms. CONCLUSION: The treatment recommendations for most topics addressed differed between the best-practice setting and resource-limited setting, accentuating the need for high-quality evidence that contemplates the effect of limited resources on the management of mCSPC.

ABSTRACT Background and Aims: An association between non-alcoholic fatty liver disease (NAFLD) and pancreatic ductal adenocarcinoma (PDAC) has been previously suggested. This study aims at investigating this association and at identifying potential links between variables of the NAFLD spectrum and PDAC. Methods: A cross-sectional case-matched analytical and comparative study was carried out to analyze patients undergoing surgical resection of PDAC and compare them to a control group of individuals undergoing cholecystectomy at a public tertiary teaching hospital, matched by sex, age and BMI. Hepatic histopathological examinations were compared between cases and controls. Results: Of 56 individuals, 36 were male (64.3%) and the median age was 61.5 years old (interquartile range: 57.5 - 70). The participants' median BMI was 24.3 kg/m2 (interquartile range: 22.1-26.2 kg/m2). Microvesicular steatosis (p=0.04), hepatocellular ballooning (p=0.02), fibrosis (p=0.0003) and steatohepatitis (p=0.03) were significantly more frequent in the group of cases. Odds ratios for hepatocellular ballooning (6.2; 95%CI: 1.2-31.8; p=0.03), fibrosis (9.3; 95%CI: 2.5-34.1; p=0.0008) and steatohepatitis (3.9; 95%CI: 1.1-14.3; p=0.04) were statistically significant in relation to the PDAC prevalence. Conclusions: Significant associations were identified between histopathological aspects of NAFLD (microvesicular steatosis, hepatocellular ballooning, fibrosis, and steatohepatitis) and PDAC.


RESUMO Histórico e objetivos: a associação entre a doença hepática gordurosa não alcoólica (DHGNA) e o adenocarcinoma ductal pancreático (ACDP) foi sugerida anteriormente. Este estudo visa investigar esta associação e identificar possíveis ligações entre as variáveis do espectro da DHGNA e o ACDP. Métodos: foi realizado estudo transversal caso-controle analítico e comparativo para analisar pacientes submetidos a ressecção cirúrgica de ACDP e compará-los a grupo controle de indivíduos submetidos a colecistectomia em hospital público terciário de ensino, pareados por sexo, idade e IMC. Os exames histopatológicos hepáticos foram comparados entre casos e controles. Resultados: dos 56 indivíduos, 36 eram do sexo masculino (64,3%) e a idade mediana era de 61,5 anos de idade (intervalo interquartil 57,5-70). A mediana do IMC dos participantes foi de 24,3 kg/m2 (intervalo interquartil 22,1 26,2). Esteatose microvesicular (p = 0,04), balonização hepatocelular (p = 0,02), fibrose (p = 0,0003) e esteato-hepatite (p = 0,03) foram significativamente mais frequentes no grupo de casos. As razões de chances para balonização hepatocelular (6,2; IC 95%: 1,2 - 31,8; p = 0,03), fibrose (9,3; IC 95%: 2,5 - 34,1; p = 0,0008) e esteato-hepatite (3,9; IC 95%: 1,1 - 14,3; p = 0,04) foram estatisticamente significativas em relação à prevalência de ACDP. Conclusões: houve associações significativas entre aspectos histopatológicos de DHGNA (esteatose microvesicular, balonização hepatocelular, fibrose e esteato-hepatite) e a ocorrência de ACDP.

RESUMO

CONTEXT: Pancreatic metastases from primary malignant tumors at other sites are rare, constituting about 2% of the neoplasms that affect the pancreas. Pancreatic metastasis from breast cancer is extremely rare and difficult to diagnose, because its clinical and radiological presentation is similar to that of a primary pancreatic tumor. CASE REPORT: A 64-year-old female developed a lesion in the pancreatic tail 24 months after neoadjuvant therapy, surgery and adjuvant radiation therapy for right-side breast cancer (ductal carcinoma). She underwent distal pancreatectomy with splenectomy and left adrenalectomy, and presented an uneventful outcome. The immunohistochemical analysis on the surgical specimen suggested that the lesion originated from the breast. CONCLUSION: In cases of pancreatic lesions detected in patients with a previous history of breast neoplasm, the possibility of pancreatic metastasis should be carefully considered.

RESUMO

BACKGROUND: Occurrences of mesenchymal tumors have been more recognized in recent years, and the incidental diagnosis of these lesions during bariatric surgery has been previously reported. OBJECTIVE: To describe the cases of incidentally diagnosed mesenchymal tumors during consecutive bariatric surgeries. SETTING: Private health-providing service, Brazil. METHODS: A retrospective population-based study, which enrolled individuals who consecutively underwent Roux-en-Y gastric bypass at a single center from January 2006 through July 2016. RESULTS: Of 1502 individuals, there were 16 cases (1.1%) of confirmed mesenchymal tumors. Of these 16 cases, 14 (87.5%) were gastrointestinal stromal tumors and 2 (12.5%) were leiomyomas. The affected individuals were significantly older (aged 46.2 ± 6.3 versus 35.4 ± 7.2 yr; P = .00031), presented a lower body mass index (38.2 ± 5.1 versus 45.3 ± 8.1 kg/m2; P<.00001), and had a lower weight (102.1 ± 17.9 versus 121.1 ± 7.4 kg; P = .00321). None of the individuals presented reported relapses of the mesenchymal tumors. CONCLUSION: The possibility of incidental gastric mesenchymal tumors during bariatric surgery should not be neglected; a careful inventory of the stomach at the beginning of the procedure and resection of lesions found are mandatory.

RESUMO

INTRODUCTION: Pancreaticopleural fistula is a rare complication of chronic pancreatitis. OBJECTIVE: To describe pancreaticopleural fistula due to chronic pancreatitis and perform an extensive review of literature on this topic. METHODS: Comprehensive narrative review through online research on the databases Medline and Lilacs for articles published over the last 20 years. There were 22 case reports and four case series selected. RESULTS: The main indication for surgical treatment is the failure of clinical and/or endoscopic treatments. Surgery is based on internal pancreatic drainage, especially by means of pancreaticojejunostomy, and/or pancreatic resections. CONCLUSION: Pancreaticopleural fistula is a rare complication of chronic pancreatitis and the Frey procedure may be an appropriate therapeutic option in selected cases when clinical and endoscopic treatments are unsuccessful.

RESUMO

CONTEXT: Gastric stump cancer after gastric resection is a well-known disease. It may be a newly developed cancer after resection due to benign disease, or recurrent or residual disease after oncological surgery. The predominant histological type is usually adenocarcinoma. This study aimed to report on a rare occurrence of a mixed adenoneuroendocrine carcinoma (MANEC) on the gastric stump. CASE REPORT: The case of an 83-year-old female who presented a locally aggressive gastric stump MANEC, 35 years after Billroth II gastrectomy to treat a peptic ulcer, is reported. The patient underwent resection and adjuvant therapy. She has been followed up for one year without signs of recurrence. CONCLUSION: MANEC is a rare type of gastrointestinal neoplasm. The classification, histopathology, clinical features, treatment issues and prognosis are discussed along with a brief review of the literature.


CONTEXTO: O câncer de coto gástrico após gastrectomia é uma condição extensamente documentada. Pode se tratar de doença desenvolvida após a ressecção por doença benigna, ou ainda doença recorrente ou residual após cirurgia oncológica. Geralmente, o tipo histológico predominante é o adenocarcinoma. Este estudo tem como propósito relatar a rara ocorrência de um adenocarcinoma neuroendócrino misto (MANEC) no coto gástrico. RELATO DE CASO: É relatado o caso de uma mulher de 83 anos que apresentou um MANEC localmente agressivo 35 anos após uma gastrectomia à Billroth II devido a úlcera péptica. Foi submetida a ressecção e terapia adjuvante e foi seguida por 12 meses sem sinais de recorrência. CONCLUSÃO: Os MANECs constituem raro tipo de neoplasia gastrointestinal. Sua classificação, histopatologia, aspectos clínicos, tratamento e prognóstico são discutidos junto com uma breve revisão de literatura.

RESUMO

Birth asphyxia can be an early sign of cerebral palsy, the effect of an antenatal anomaly rather than its cause. The objective of this study was to evaluate the occurrence of intrapartum complications in patients with malformation of cortical development. The data were retrospectively assessed and compared with a control group of children with idiopathic epilepsy. Intrapartum complications were reported in 22 (31.5%) patients, as opposed to only 2 in the control group (p < 0.001). Patients with cortical malformations frequently present intrapartum complications, which could lead to the misdiagnosis of hypoxic-ischemic encephalopathy.
