RESUMEN
Purpose: Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare primary liver malignancy often diagnosed at advanced stages. While there are limited data on the efficacy of specific agents, we aim to report outcomes of patients treated with systemic therapies and explore prognostic factors. Patients and Methods: Medical records of patients treated between 2010 and 2022 were reviewed. Treatments were defined after multidisciplinary assessment. Descriptive statistics were used for baseline demographics. Time-to-event outcomes were estimated using the Kaplan-Meier method, compared by log-rank and adjusted by a regression model. Radiomic features (including size, shape, and texture) of the primary lesion were extracted and dimensionality reduced. An unsupervised Gaussian Mixture Model (GMM) clustering was performed, and survival was compared between clusters. Results: We identified 23 patients: 12 males, with a median age of 23.6 years. At diagnosis, 82.6% had metastases, most frequently to the lungs (39.1%), lymph nodes (39.1%), and peritoneum (21.7%). Patients received a median of three lines (1-8) of treatment, including different regimens. Sorafenib (39.1%), capecitabine (30.4%), and capecitabine/interferon (13%) were the most used first-line regimens. The median time-to-failure was 3.8 months (95% CI: 3.2-8.7). Capecitabine + interferon (42.1%) and platinum combinations (39.1%) were the most used second-line regimens, with a time-to-failure of 3.5 months (95% CI: 1.5-11.6). Median overall survival was 26.7 months (95% CI: 15.1-40.4). A high baseline neutrophil-to-lymphocyte ratio (NLR) was associated with worse survival (p=0.02). Radiomic features identified three clusters, with one cluster (n=6) having better survival (40.4 vs 22.6 months, p=0.039). Tumor sphericity in the arterial phase was the most relevant characteristic associated with a better prognosis (accuracy=0.93). Conclusion: FLHCC has unique features compared to conventional HCC, including young onset, gender balance, and absence of hepatopathy. Systemic therapies can provide encouraging survival, but lack of uniformity precludes defining a preferable regimen. Radiomics and NLR were suggested to correlate with prognosis and warrant further validation.
RESUMEN
Prognostic markers in advanced hepatocellular carcinoma (HCC) are relevant for clinical decisions. Variations in inflammatory indexes, such as neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte ratio (PLR), may correlate with outcomes. In the present study, it was aimed to assess the prognostic role of inflammation indexes in patients with HCC and the evolutionary behavior of these variables within the first month of treatment in a cohort of patients treated with sorafenib from 2009-2021. Subgroups were divided based on the median of each variable ('low' or 'high)'. Survival was estimated using the Kaplan-Meier method. Hazard Ratio (HR) with 95% confidence interval (CI) were estimated using Cox regression models. A total of 373 patients were included, most Child-Pugh-A (83.1%) and BCLC-C (74%). Child-Pugh-A (P=0.011), performance status 0 (P<0.001), no ascites (P<0.001) and NLR<2.6 (P<0.001) were independently associated with improved survival. Baseline PLR was not correlated with survival (P=0.137). Patients who maintained low NLR at baseline and at 1 month (reference subgroup) had improved survival (18.6 months, 95% CI:15.4-22.0) compared with the subgroup that maintained high NLR at baseline and at 1 month (4.2 months, 95% CI:3.6-5.9), with HR: 3.80 (95% CI: 2.89-4.96). The subgroup with low NLR at baseline and high NLR at 1 month had a worse prognosis compared with the reference group (HR:1.4, 95% CI: 1.1-2.0), whereas the subgroup with high NLR at baseline and low at 1 month had similar outcome (HR:1.2, 95% CI: 0.8-1.6). It was concluded that evolutionary variation of NLR has a prognostic role in HCC patients under systemic therapy. This finding suggested that systemic inflammation and early modulation of the immune environment during treatment may correlate with outcomes.
RESUMEN
Introduction and objectives: The incidence of cholangiocarcinoma (CCA) has been increasing globally. Although a concomitant increase in the incidence of metabolic disorders might suggest a causal relationship, the data are scarce. We aimed to describe the prevalence of metabolic disorders in patients with CCA and report the clinical features and outcomes. Patients and Methods: Retrospective study including patients with CCA. Patients were divided into: (1) past history of diabetes or/and overweight/obesity ("metabolic disorder group") and (2) without any of these features ("non-metabolic-disorder group"). A Cox regression model was used to determine the prognostic factors. Results: 122 patients were included. In total, 36 (29.5%) had overweight/obesity, 24 (19.7%) had diabetes, and 8 (6.6%) had both. A total of 29 (23.8%) patients had resectable disease and received upfront surgery. A total of 104 (85.2%) received chemotherapy for advanced/recurrent disease. The overall survival of the cohort was 14.3 months (95% CI: 10.1−17.3). ECOG-PS 0 (p < 0.0001), resectable disease (p = 0.018) and absence of vascular invasion (p = 0.048) were independently associated with better prognosis. The "metabolic disorder group" (n = 52) had a median survival of 15.5 months (95% CI 10.9−33.9) vs. 11.5 months (95% CI 8.4−16.5) in the "non-metabolic-disorder group" (n = 70) (HR: 1.10; 95% CI 0.62−1.94). Patients with resectable disease in the "metabolic group" had longer survival than patients in the "non-metabolic group" (43.4 months (95% CI 33.9-NR) vs. 21.8 months (95% CI 8.6−26.9); HR = 0.12, 95% CI 0.03−0.59). Conclusion: Metabolic disorders are frequent among CCA patients. Underlying metabolic comorbidities may be associated with prognosis in resectable CCA. There is a need to explore the mechanism that drives CCA carcinogenesis in a metabolic background.
RESUMEN
Aim of the study: Hepatocellular carcinoma (HCC) is a lethal malignancy with heterogeneous behavior determined by liver function, clinical presentation and treatment response. Peritoneal metastasis (PM) from HCC is rare and management is challenging. We aim to report a cohort of patients with advanced HCC and describe demographic characteristics, treatment and outcomes of patients with PM. Material and methods: We analyzed data from a retrospective cohort of patients with HCC. Patients with PM were analyzed individually. Baseline characteristics, treatment strategy and median overall survival (OS) with 95% confidence interval (CI) were reported. Results: 238 patients with advanced HCC were evaluated. Eleven patients had PM: 7 patients were treated with systemic treatment and 4 were treated with upfront peritonectomy followed by systemic treatment at recurrence. These 4 patients had well-preserved liver function and low disease burden and were younger compared to the total cohort. The median time to recurrence after peritonectomy was 30.25 months (interquartile range [IQR]: 13.53-46.92): 3 of them presented peritoneal recurrence (2 with diffuse peritoneal spread and 1 with concomitant hepatic recurrence) and 1 presented pulmonary recurrence. Overall, patients with PM showed similar OS compared to patients with other metastatic sites (11.8 months; 95% CI: 1.5-19.8 vs. 8 months; 95% CI: 6.7-10, p = 0.901). Patients with PM treated with upfront surgery had a median OS of 60 months (95% CI: 16.7-not reached). Conclusions: Resection of PM from HCC may provide long-term survival in selected patients. A multidisciplinary approach is the optimal strategy for managing PM from HCC.
RESUMEN
OBJECTIVES: To evaluate the efficacy and safety of sorafenib in elderly patients with advanced hepatocellular carcinoma (HCC). METHODS: We analyzed data from a cohort of patients with advanced HCC treated using systemic treatment according to the local institutional protocol. Patients were divided into two groups, Group A, individuals <70 years of age, and Group B, individuals 70 years of age or older at the time of treatment initiation. Efficacy, measured based on overall survival (OS) and time to treatment failure (TTF), and toxicity were compared between groups. RESULTS: A total of 238 patients with advanced HCC who received sorafenib between 2007 and 2018 were evaluated. The median age for Group A was 59.1 years and that for Group B 73.6 years. The major prognostic characteristics were balanced between the groups. There were no significant differences in OS between Group A (8.0 months, 95%CI 6.34-9.3) and Group B (9.0 months, 95%CI 5.38-12.62), p=0.433, or in TTF between Group A (3.0 months, 95%CI 2.39-3.60) and Group B (3.0 months, 95%CI 1.68-4.32), p=0.936. There were no significant differences between Groups A and B with respect to the incidence of adverse events or treatment discontinuation because of toxicity. CONCLUSION: Efficacy and safety of sorafenib did not differ significantly between younger and older patients with HCC. Our data suggest that age alone should not restrict clinical decision-making for patients with advanced HCC.

Sorafenib was the first tyrosine kinase inhibitor (TKI) that showed success in extending survival in patients with advanced hepatocellular carcinoma (HCC). In recent years, additional TKIs have been shown to improve survival and expanded the armamentarium for treating this malignancy. The current landscape includes other classes of drugs, such as immune checkpoint inhibitors and monoclonal antibodies. The challenge is now placed on how to best select, combine, and sequence drugs with the goal of improving efficacy and minimizing toxicities to deliver better outcomes for HCC patients.

Background: Anti-EGFR antibodies are a standard care for advanced KRAS-wild type colorectal cancers. Circulating tumor DNA (ctDNA) monitoring during therapy can detect emergence of KRAS mutant clones and early resistance to therapy. Case Presentation: We describe a 61-years-old man presenting a metastatic and recurrent rectal cancer treated with different chemotherapy regimens. His tumor was KRAS wild-type based on tissue analysis and he was treated sequentially with cetuximab-based chemotherapy, chemotherapy alone and panitumumab-based chemotherapy. We performed sequential analysis of ctDNA using droplet digital PCR (ddPCR) and a commercial assay designed for the detection of frequent KRAS mutations during his clinical follow-up. Prior to the first cetuximab-based chemotherapy ctDNA analysis demonstrated an absence of KRAS mutations. Emergence of KRAS mutations in ctDNA occurred ~3 months after treatment initiation and preceded clinical and imaging progression in about 2 months. Fractional abundance of KRAS mutation rapidly increased to 70.7% immediately before a chemotherapy alone regimen was initiated. Interestingly, KRAS mutation abundance decreased significantly during the first two months of chemotherapy, reaching a fractional abundance of 3.0%, despite minimal clinical benefit with this therapy. Re-challenge with a different anti-EGFR antibody was attempted as later line, but high levels of KRAS mutations in ctDNA before therapy correlated with an absence of clinical benefit. Conclusions: The monitoring of resistance mutations in KRAS using ctDNA during the treatment of KRAS wild-type advanced colorectal cancers can detect the emergence of resistant clones prior to clinical progression. Dynamics of resistant clones may alter during periods on and off anti-EGFR antibodies, detecting window of opportunities for a re-challenge with these therapies.
RESUMEN
BACKGROUND: Recent studies report increasing incidence of colorectal cancer (CRC) in the young-age population, but data concerning clinical behavior, pathologic findings, and prognosis are controversial for this group. Early recognition of CRC in young patients is a challenge and diagnosis at advanced stage is clearly associated with worse outcomes. MATERIALS AND METHODS: We retrospectively reviewed medical records of 5806 patients diagnosed with CRC between January/2011 and November/2016 and identified 781 patients aged less than 50-years-old. RESULTS: We found an absolute increasing in the incidence of CRC in patients <50 years old of 1.88%-2.23% annually, with a relative increasing of 35.3% between 2011 and 2016. Median age was 42 years, 57.4% were female and 20.9% reported family history of CRC. Left-sided tumors were more frequent and the majority of patients were symptomatic. The most common stages at diagnosis were III (34.1%) and IV (37.3%). The median overall survival (OS) for stage IV was 25 months (95% CI 20.7-29.3) and was not reached for Stages I-III (P < 0.001). Family history of CRC was independently associated with better OS in stage IV(Pâ¯=â¯0.02). For stages I-III, wild-type KRAS, family history of CRC, and absence of angiolymphatic invasion were associated with better OS (Pâ¯=â¯0.02, Pâ¯=â¯0.01 and P < 0.001, respectively). CONCLUSIONS: In our cohort, the incidence of early-onset CRC is increasing over the past years. Young patients were more likely to be diagnosed with metastatic disease, left-sided and/or rectum site and symptoms at presentation. These findings highlight the emerging importance of young-age onset CRC and the need to discuss strategies to early diagnosis.

BACKGROUND: In North America and Europe, return-to-work (RTW) rates vary among breast cancer (BC) survivors, from 24% to 66% and from 53% to 82% at 6 and 36 months after diagnosis, respectively. To date, there is a lack of data on RTW rates after BC diagnosis in Latin America. Therefore, the primary objectives of this study were to define RTW rates at 12 and 24 months after BC diagnosis and to identify the factors associated with RTW in this population. METHODS: In total, 125 employed women from a single institution with newly diagnosed BC were interviewed by telephone at 6, 12, and 24 months after diagnosis. Those who had inoperable or metastatic disease were excluded. RESULTS: Overall, RTW rates were 30.3% and 60.4% at 12 and 24 months after BC diagnosis, respectively. Most women reported that they received support from their employer, but only 29.1% reported having been offered work adjustments. In multivariate analysis, the factors associated with positive RTW outcomes included higher household income (odds ratio [OR], 17.76; 95% confidence interval [CI], 3.33-94.75; P = .001), breast-conserving surgery (OR, 9.77; 95% CI, 2.03-47.05; P = .004), and work adjustments (OR, 37.62; 95% CI, 2.03-47.05; P = .004). The factors associated with negative RTW outcomes included adjuvant endocrine therapy (OR, 0.11; 95% CI, 0.02-0.74; P = .023), and depression diagnosed after BC (OR, 0.07; 95% CI, 0.01-0.63; P = .017). CONCLUSIONS: RTW rates in the current study were lower than those observed in developed countries but similar to the rates among low-income Americans. Workplace adjustments, higher income, breast-conserving surgery, endocrine therapy, and depression after BC played an important role in the RTW decision.
