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.

El carcinoma hepatocelular (HCC) es el tumor primario más frecuente del hígado, con 905 677 casos diagnosticados en 2020, en todo el mundo, y 830 180 muertes.

Abstract 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 under went 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.

Do changes in inflammatory markers predict hepatocellular carcinoma recurrence and survival after liver transplantation?

BACKGROUNDS/AIMS: The role of inflammation in malignant cell proliferation has been well described. High values of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) as markers of systemic inflammation have shown associations with unfavorable long-term outcomes. The purpose of this study was to determine values of NLR and PLR evaluated prior to and after surgery and their associations with mortality and recurrence rates of liver transplant patients with hepatocellular carcinoma (HCC). METHODS: A total of 105 patients with HCC who underwent orthotopic liver transplantation (OLT) were retrospectively reviewed. NLR and PLR values were obtained from complete blood counts prior to and after surgery. Overall survival (OS) and recurrence-free survival (RFS) in relation with delta NLR and PLR were estimated. RESULTS: Serum alpha-fetoprotein levels > 100 ng/mL (p = 0.014) and lymphovascular emboli in the specimen (p = 0.048) were identified to be significant predictors of RFS. Child-Pugh score (p = 0.016) was found to be an independent factor associated with poorer OS. An increasing delta PLR was associated with worse RFS, although it showed no significant association with OS. CONCLUSIONS: The analysis of PLR as a continuous variable may predict recurrence outcomes in patients undergoing OLT for HCC. It is more representative than isolated values.

Is the neutrophil-to-lymphocyte ratio a prognostic factor in non-small cell lung cancer patients who receive adjuvant chemotherapy?

Inflammation plays a key role in malignant tumor progression. Neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation and, as such, high isolated pretreatment NLR has been shown in some studies to be associated with worse long-term outcomes. We summarize the data regarding the utility of NLR as a prognosis factor and present results of a single institution study assessing the usefulness of high preoperative NLR as a prognosis factor for patients with successfully resected NSCLC who receive adjuvant cisplatin-based chemotherapy. While largely supportive of the value of NLR as a prognostic factor, the literature is not consistent and suggest a more nuanced association. Our single institution study adds to the exiting literature. We conclude preoperative NLR can be used as a reliable, cost-effective biomarker to estimate prognosis in NSCLC patients who have undergone lung lobectomy with curative intent followed by cisplatin-based adjuvant chemotherapy.
