e16609 Background: The Barcelona-Clinic Liver Cancer (BCLC) staging based management proposed by AASLD depends on baseline liver function and performance status of the patient in addition to tumor characteristics. Low adherence to AASLD guidelines, especially in advanced staged tumors, can be ascribed to suboptimal revision/updates of the guidelines reflecting the advancements in hepatocellular carcinoma (HCC) management. Here, in addition to the adherence rate, we explored the overall survival of patients with HCC according to first-line treatment modality compliance to AASLD guidelines. Methods: This is a retrospective study conducted at the University of South Alabama/Mitchell Cancer Institute. Between 2017 and 2019, 148 unique treatment-naïve patients with HCC were identified. Patients were staged according to the BCLC staging system and their compliance with suggested first-line treatment modality according to AASLD guidelines was noted. Overall survival was explored and differences between overall survival rates of compliant and non-complaint patients were compared using the log-rank Wilcoxon test. Results: In our cohort, the median age was 72.5 years (range 38-90). Males represented 80%. Caucasians, African Americans, and other ethnicities (e.g. Asians) represented 68%, 30% and 2% respectively. The overall adherence rate was 83%. The adherence rate according to BCLC stage 0, A, B, C and D was 100%, 97%, 77%, 77% and 38% respectively. Compliance vs. non-compliance to AASLD guidelines showed no significant difference in overall survival of patients with BCLC stage 0-A, B and C. In patients with BCLC stage D (N = 13), compared to patients treated in compliance to AASLD guidelines (N = 5), patients treated in non-compliance (N = 8) had better overall survival (2.2 vs. 5.2 months, p = 0.0012). Conclusions: In our cohort, the adherence rate to AASLD treatment guidelines in patients with BCLC stage D was very low at 38%. Lack of adherence in this group of patients translated into better overall survival. The current AASLD guidelines for the management of HCC have several limitations, especially for advanced stages. In the last few years, the FDA approved several tyrosine kinase inhibitors, immune checkpoint inhibitors and the monoclonal antibody, ramucirumab. This expansion generated the need for periodic updates/revisions of consensus guidelines.
At 9%, and 2% when diagnosed at advanced stage, the 5-year relative survival rate for pancreatic ductal adenocarcinoma (pdac) is the lowest of any cancer. The currently approved treatment options for metastatic pdac in the United States are folfirinox [irinotecan–fluorouracil (5fu)–leucovorin (lv)–oxaliplatin], gemcitabine–nab-paclitaxel, and liposomal irinotecan plus 5fu–lv.
Liposomal irinotecan is a novel formulation of irinotecan encapsulated within a lipid bilayer, which favours localmetabolic activation. The napoli-1 trial demonstrated the efficacy of liposomal irinotecan in combination with 5fu and lv for the treatment of advanced pdac after progression on gemcitabine-based chemotherapy. The 1-year survival in those patients was 25%; however, none had had irinotecan-refractory disease before treatment with liposomal irinotecan. Furthermore, the U.S. National Comprehensive Cancer Network guidelines recommend liposomal irinotecan plus 5fu–lv in patients who have received prior fluoropyrimidine-based therapy if no prior irinotecan therapy has been given. Here, we report a male patient with stage iv cancer of pancreas or bile duct (site unconfirmed) who experienced a prolonged (51 weeks) response to liposomal irinotecan plus 5fu–lv despite prior disease progression on irinotecan. Several factors have previously been associated with long-term survival in patients receiving liposomal irinotecan therapy: no prior irinotecan-based chemotherapy, high Karnofsky performance status score, age 65 years or less, serum carbohydrate antigen 19-9 less than 59 U/mL, neutrophil-to-lymphocyte ratio 5 or less, and absence of liver metastasis. The patient in the present report had none of those characteristics indicative of long-term survival, except his age at diagnosis—47 years.
