Key clinical point: Infectious complications during curative resection for HCC significantly reduced overall survival and recurrence-free survival; outcomes were even worse for patients with non-surgical site infections vs surgical site infections.

Major finding: A total of 269 patients experienced a postoperative complication. Overall survival was significantly shorter in HCC patients who experienced infectious complications after curative surgery compared to those who did not (46.5 months vs 106.4 months, P < 0.001).

Study details: The data come from 734 adults with hepatocellular carcinoma who underwent curative resection between 2000 and 2017.

Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.

Key clinical point: Liver stiffness was a stronger predictor of symptomatic post-hepatectomy liver failure in HCC patients after major hepatectomy compared to CTP grade, and was significantly more effective for stratifying SPHLF risks in CTP grade A for both major and minor hepatectomy.

Major finding: Liver stiffness of 9.5 kPa or greater, as measured by measured by two-dimensional shear wave elastography, was superior to Child-Turcotte-Pugh (CTP) grade for predicting symptomatic post-hepatectomy liver failure after major hepatectomy (72.4% vs 18.9%), although CTP was more effective at predicting liver failure after minor hepatectomy (100% vs 12.2%).

Key clinical point: Nomograms for both recurrence-free survival and overall survival based on tumor clinical features, operative factors, liver function, and systemic inflammatory or immune status were effective predictors for stratifying SLH-HCC patients in low-, medium-, and high-risk groups.

Major finding: Nomograms for post-surgical recurrence-free survival and overall survival in patients with SLH-HCC achieved C-indexes of 0.85 and 0.86, respectively. The nomograms were based on diameter, differentiation, microvascular invasion, α-fetoprotein, preoperative transcatheter arterial chemoembolisation therapy, scope of liver resection and intraoperative blood transfusion, albumin-bilirubin grade, and neutrophil-to-lymphocyte ratio.

Study details: The data come from a retrospective study of 2,469 adult patients with single large and huge hepatocellular carcinoma (SLH-HCC) defined as greater than 5.0 cm in diameter who underwent curative resection between January 2005 and December 2015.

Key clinical point: Approximately half of chronic hepatitis C patients required HCC treatment after a sustained viral response by direct-acting antivirals (DAA).

Major finding: Cumulative 5-year HCC recurrence was 45% and 65%, of hepatitis C patients in curative and palliative treatment groups, respectively. Predictors of early recurrence included AFP greater than 7 ng/mL at 12 weeks after DAA, time from HCC complete response (CR) to DAA initiation of less than 1 year, and the two or more HCC treatments necessary to achieve CR. Predictors of late recurrence included cirrhosis (hazard ratio 1.85), two or more HCC nodules (HR 1.52), and previous palliative HCC treatment (HR 1.71).

Study details: The data come from a retrospective, multicenter cohort study of 365 consecutive adults with chronic hepatitis C who required treatment for HCC after hepatitis C cure via direct-acting antivirals.

Key clinical point: The albumin-bilirubin (ALBI) grade and alpha-fetoprotein (AFP) level of HCC patients at the start of regorafenib therapy was an independent predictor of disease control, progression-free survival after regorafenib therapy, and overall survival for both regorafenib and sorafenib-regorafenib sequential therapy.

Major finding: HCC patients with ALBI grade 2 and AFP level of 20 ng/mL or higher had worse rates of both progression-free survival for regorafenib alone (hazard ratio 3.088) and of overall survival for both regorafenib (HR 3.783) and sorafenib-regorafenib sequential therapy (HR 4.603) compared to those with ALBI grade one and lower AFP levels.

Key clinical point: Pre-emptive oral treatment with clarithromycin (CAM) together with relatively simple skin care effectively suppressed the development of panitumumab-induced grade 2 or more skin toxicities in patients with metastatic colorectal cancer (mCRC).

Major finding: Grade 2 or more skin toxicities within the first 6 weeks were 68% lower in the group receiving CAM in combination with skin care vs only skin care (hazard ratio, 0.32; P less than .001). Rates of other adverse events were not different between the groups; however, grade 3 or more diarrhea was higher in patients receiving CAM (8.0% vs 1.3%).

Study details: Findings are from a phase 3 study involving 156 patients with mCRC treated with panitumumab who were randomly assigned to either pre-emptive antibiotic treatment with CAM through the panitumumab treatment in combination with skin care or control regimen consisting of only skin care.

Major finding: Females vs males had more frequent grade 2 or more TRAEs during the first cycle of treatment (84% vs 60%; P = .002) and grade 3 or more TRAEs throughout the treatment (71% vs 53%; P = .035), with sex being the only independent predictive factor for early grade 2 or more (odds ratio [OR], 3.4; P = .02) and late grade 3 or more (OR, 2.1; P = .045) TRAEs.

Key clinical point: Among patients with stenotic left‐sided colorectal cancer (CRC) who underwent incomplete colonoscopy, absence of negative preoperative 18‐fluoro‐2‐deoxy‐glucose (FDG)‐avid lesions in the proximal colon other than the target CRC ensures the absence of additional lesions warranting changes in surgical plan.

Major finding: The cumulative detection rate of advanced adenoma was significantly higher in the incomplete vs complete colonoscopy group at 1 year (6.3% vs 0.7%) and 5 years (12.5% vs 9.9%; P = .012). However, the cumulative rate of detection of adenocarcinoma at 1 and 5 years (P = .15) and 5-year cumulative rate of additional surgery (P = .85) were not different between the groups.

Study details: Findings are from an analysis of 754 patients with left‐sided CRC without synchronous FDG‐avid lesions on preoperative 18‐FDG positron emission tomography/computed tomography. Patients were categorized into those who underwent complete (n=616) and incomplete (n=138) preoperative colonoscopy.

Key clinical point: Among patients with stenotic left‐sided colorectal cancer (CRC) who underwent incomplete colonoscopy, absence of negative preoperative 18‐fluoro‐2‐deoxy‐glucose (FDG)‐avid lesions in the proximal colon other than the target CRC ensures the absence of additional lesions warranting changes in surgical plan.

Major finding: The cumulative detection rate of advanced adenoma was significantly higher in the incomplete vs complete colonoscopy group at 1 year (6.3% vs 0.7%) and 5 years (12.5% vs 9.9%; P = .012). However, the cumulative rate of detection of adenocarcinoma at 1 and 5 years (P = .15) and 5-year cumulative rate of additional surgery (P = .85) were not different between the groups.

Study details: Findings are from an analysis of 754 patients with left‐sided CRC without synchronous FDG‐avid lesions on preoperative 18‐FDG positron emission tomography/computed tomography. Patients were categorized into those who underwent complete (n=616) and incomplete (n=138) preoperative colonoscopy.
