RESUMO

BACKGROUND AND OBJECTIVES: Tumor-infiltrating lymphocytes (TILs) represent a host-tumor interaction, frequently signifying an augmented immunological response. Nonetheless, implications with survival outcomes in patients with colorectal carcinoma liver metastasis (CRLM) warrant rigorous validation. The objective was to demonstrate the association between TILs and survival in patients with CRLM. METHOD: In a retrospective evaluation conducted in a single institution, we assessed all patients who underwent hepatectomy due to CRLM between 2014 and 2018. Comprehensive medical documentation reviews were executed. TILs were assessed by a liver pathologist, blinded to the clinical information, in all surgical slides. RESULTS: This retrospective cohort included 112 patients. Median overall survival (OS) was 58 months and disease-free survival (DFS) was 12 months for the entire cohort. Comparison between groups showed a median OS of 81 months in the dense TILs group and 40 months in the weak/absent group (p = 0.001), and DFS was 14 months versus 9 months (p = 0.041). Multivariable analysis showed that TILs were an independent predictor of OS (HR 1.95; p = 0.031). CONCLUSIONS: Dense TILs are a pivotal prognostic indicator, correlating with enhanced OS. Including TILs information in histopathological evaluations should refine the clinical decision-making process for this group of patients.

RESUMO

RESUMEN La enfermedad de Caroli es un trastorno congénito causado por malformación de la placa ductal. Se manifiesta con litiasis intrahepática y colangitis recurrente, habitualmente en personas jóvenes. Los hallazgos imagenológicos incluyen dilatación multifocal y segmentaria de los conductos biliares intrahepáticos. El colangiocarcinoma puede aparecer como complicación a largo plazo debido a la inflamación crónica de los conductos, por lo que debe estar siempre presente dentro de los posibles diagnósticos diferenciales. Se describe el caso infrecuente de una mujer de 52 años que presentó un cuadro de obstrucción biliar poscolecistectomía laparoscópica y requirió en su tratamiento quirúrgico la resección de los segmentos hepáticos II y III por enfermedad de Caroli, con buena evolución.


ABSTRACT Caroli's disease is a congenital disorder caused by a defect of the ductal plate. The clinical picture includes intrahepatic duct lithiasis and recurrent cholangitis usually in young people. The imaging tests reveal the presence of multifocal and segmental dilatation of the intrahepatic bile ducts. Cholangiocarcinoma can develop as a long-term complication of chronic bile duct inflammation and should always be considered as a differential diagnosis. We describe a rare case of a 52-year-old woman who presented with bile duct obstruction after laparoscopic cholecystectomy and required resection of liver segments II and III due to Caroli's disease with a favorable outcome.

RESUMO

INTRODUCTION AND AIMS: Hepatocellular carcinoma (HCC) is a primary malignant tumor of liver epithelial cells and is the most frequent primary liver cancer. The broadening of transplantation and resectability criteria has made therapeutic decisions more complex. Our aim was to describe the clinical and survival characteristics of patients with HCC treated through resection or liver transplantation at our hospital and identify the presence of factors that enable outcome prediction and facilitate therapeutic decision-making. MATERIALS AND METHODS: Patients with HCC that underwent surgery with curative intent at the Hospital Universitario Marqués de Valdecilla, within the time frame of 2007 and 2017, were retrospectively identified. Survival, mortality, disease-free interval, and different outcome-related variables were analyzed. RESULTS: Ninety-six patients with a mean follow-up after surgery of 44 months were included. Overall mortality and recurrence were higher in the resection group. Mean survival was 51.4 months in the liver transplantation group and 37.5 months in the resection group, and the disease-free interval was 49.4 ±â€¯37.2 and 27.4 ±â€¯28.7 months, respectively (p = 0.002). The tumor burden score was statistically significant regarding risk for recurrence and specific mortality. CONCLUSIONS: There appears to be no patient subgroup in whom the results of surgical resection were superior or comparable to those of transplantation. Tumor burden determination could be a useful tool for patient subclassification and help guide therapeutic decision-making.

RESUMO

BACKGROUND: Management of benign liver lesions (BLLs) is still an object of discussion. Frequently, patients receive multiple opinions about their diagnosis and treatment from physicians specialized in different areas, which can be opposite and controversial. This study aimed to understand patients' decision-making process in electing surgery and assess their satisfaction after resection for BLLs. METHODS: A 104-question survey was administered to 98 patients who had a resection for BLLs in 4 different hepatopancreatobiliary and transplant centers in Argentina. The first section included 64 questions regarding the initial discovery of the BLL, the decision-making process, and the understanding of the patient's feelings after surgery. The second section, 42 queries, referred to the quality of life. The patient's final diagnosis and outcome were correlated with the survey results using univariate analysis. RESULTS: Among 97 patients who had undergone liver resection for BLLs, 69 (70%) completed the survey. The median age was 51.71 years (range, 18-75), and 63% of the patients were females. Moreover, 21% of patients received conflicting information from different healthcare providers. Surgeons were the best to describe the BLL to the patient (63%), and 30% of patients obtained opinions from multiple surgeons. The respondents were quite or fully satisfied with their decision to have surgery (90%) and the decision-making process (91%). Only 59% of patients considered their lifestyle better after surgery, and 89% of patients would have retaken the same decision. CONCLUSION: Patients with resected BLLs are delighted with the decision to have surgery, regardless of the final diagnosis and outcome. The role of surgeons is crucial in the decision-making process.

RESUMO

Colorectal cancer is the third most common cancer worldwide, and up to 50% of all patients diagnosed will develop metastatic disease. Management of colorectal liver metastases (CRLM) has been constantly improving, aided by newer and more effective chemotherapy agents and the use of multidisciplinary teams. However, the only curative treatment remains surgical resection of the CRLM. Although survival for surgically resected patients has shown modest improvement, this is mostly because of the fact that what is constantly evolving is the indication for resection. Surgeons are constantly pushing the limits of what is considered resectable or not, thus enhancing and enlarging the pool of patients who can be potentially benefited and even cured with aggressive surgical procedures. There are a variety of procedures that have been developed, which range from procedures to stimulate hepatic growth, such as portal vein embolization, two-staged hepatectomy, or the association of both, to technically challenging procedures such as simultaneous approaches for synchronous metastasis, ex-vivo or in-situ perfusion with total vascular exclusion, or even liver transplant. This article reviewed the major breakthroughs in liver surgery for CRLM, showing how much has changed and what has been achieved in the field of CRLM.

RESUMO

BACKGROUND: Colorectal liver metastasis has a high incidence, and RAS oncogene mutation status carries significant prognostic information. We aimed to assess whether RAS-mutated patients present more or less frequently with positive margins in their hepatic metastasectomy. METHODS: We performed a systematic review and meta-analysis of studies from PubMed, Embase, and Lilacs databases. We analyzed liver metastatic colorectal cancer studies, which included information on RAS status and had surgical margin analysis of the liver metastasis. Odds ratios were computed using a random-effect model due to anticipated heterogeneity. We further performed a subanalysis limited to studies that included only patients with KRAS instead of all-RAS mutations. RESULTS: From the 2,705 studies screened, 19 articles were included in the meta-analysis. There were 7,391 patients. The prevalence of positive resection margin was not significantly different between patients carrier vs non-carrier for the all-RAS mutations (OR .99; 95% CI 0.83-1.18; P = .87), and for only KRAS mutation (OR .93; 95% CI 0.73-1.19; P = .57). CONCLUSIONS: Despite the strong correlation between colorectal liver metastasis prognosis and RAS mutation status, our meta-analysis's results suggest no correlation between the RAS status and the prevalence of positive resection margins. The findings contribute to a better understanding of the RAS mutation's role in the surgical resections of colorectal liver metastasis.

RESUMO

El tratamiento del hemangioma hepático gigante (HHG), sigue siendo motivo de controversia. El objetivo de este estudio fue reportar los resultados de pacientes con HHG resecados quirúrgicamente en términos de morbilidad postoperatoria (MPO). Serie de casos con seguimiento. Se incluyeron pacientes con HHG, sometidos a cirugía de forma consecutiva, en Clínica RedSalud Mayor, entre 2011 y 2020. La variable resultado fue MPO. Otras variables de interés fueron: tiempo quirúrgico, estancia hospitalaria y mortalidad. Las pacientes fueron seguidas de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión. Se intervinieron 5 pacientes, con una mediana de edad de 38 años. La medianas del tiempo quirúrgico y estancia hospitalaria; fueron 75 min y 4 días respectivamente. La MPO fue 20 % (1 caso de seroma). Con una mediana de seguimiento de 41 meses, los pacientes se encuentran asintomáticos y no se ha verificado morbilidad alejada. La resección quirúrgica de un HHG se puede realizar con escasa morbilidad, tanto en términos numéricos como de gravedad de la complicación observada.


SUMMARY: Treatment of giant hepatic hemangioma (GHH) remains controversial. The aim of this study was to report the outcomes of surgically resected GHH patients in terms of postoperative morbidity (POM). Case series with follow-up. Patients with GHH who underwent surgery consecutively at the RedSalud Mayor Clinic between 2011 and 2020 were included. The outcome variable was POM. Other variables of interest were surgical time, hospital stay and mortality. The patients were followed up clinically. Descriptive statistics were used, with measures of central tendency and dispersion. Five patients underwent surgery, with a median age of 38 years. The median surgical time and hospital stay; were 75 min and 4 days respectively. The MPO was 20 % (1 case of seroma). With a median follow-up of 41 months, the patients are asymptomatic, and no distant morbidity has been verified. Surgical resection of GHH can be performed with low morbidity, both in terms of numbers and the severity of the complication observed.

RESUMO

Colorectal cancer represents the third most diagnosed malignancy in the world. The liver is the main site of metastatic disease, affected in 30% of patients with newly diagnosed disease. Complete resection is considered the only potentially curative treatment for colorectal liver metastasis (CRLM), with a 5-year survival rate ranging from 35% to 58%. However, up to 80% of patients have initially unresectable disease, due to extrahepatic disease or bilobar multiple liver nodules. The availability of increasingly effective systemic chemotherapy has contributed to converting patients with initially unresectable liver metastases to resectable disease, improving long-term outcomes, and accessing tumor biology. In recent years, response to preoperative systemic chemotherapy before liver resection has been established as a major prognostic factor. Some studies have demonstrated that patients with regression of hepatic metastases while on chemotherapy have improved outcomes when compared to patients with stabilization or progression of the disease. Even if disease progression during chemotherapy represents an independent negative prognostic factor, some patients may still benefit from surgery, given the role of this modality as the main treatment with curative intent for patients with CRLM. In selected cases, based on size, the number of lesions, and tumor markers, surgery may be offered despite the less favorable prognosis and as an option for non-chemo responders.

RESUMO

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies. The aim of this study is to characterize and describe epidemiologically patients with diagnosis of hepatocellular carcinoma in the Italian Hospital of Buenos Aires during a 12-year period. Overall survival for our cohort was 58%, 46%, and 36% at 1, 3 and 5 years respectively. Average survival for patients receiving palliative treatment was 5 months, while for those who received either non-curative or curative treatment was 23 and 75 months respectively. Recurrence-free survival for those patients who underwent a curative treatment was 89%, 76% y 61% at 1, 3 and 5 years. A thorough analysis of etiology, risk factors, incidence, mortality and treatment was made. The study's importance lies in its large sample size, quantity and quality of data, and will most certainly stimulate the development of local studies in hepatocellular carcinoma.
