Unresectable hepatocellular carcinoma at dawn of immunotherapy era: real-world data from the French prospective CHIEF cohort.

BACKGROUND AND OBJECTIVES: Hepatocellular carcinoma epidemiological data are limited in France. The Epidemio Liver Immunotherapy Tecentriq outcome research (ELITor) retrospective study, based on real-world data from the Carcinome HépatocellulaIrE en France (CHIEF) French cohort of hepatocellular carcinoma patients, aimed to get insight into the treatment patterns, the sociodemographic, clinical, biological, and etiological characteristics, and the quality of life of patients with unresectable hepatocellular carcinoma. METHODS AND RESULTS: Between 1 September 2019 and 4 December 2020, 367 patients from the CHIEF cohort received at least one locoregional (52.8%) chemoembolization or radioembolization or systemic treatment (88.3%) and were selected for ELITor. Most patients had a Barcelona Clinic Liver Cancer (BCLC) C (93.2%) hepatocellular carcinoma stage and were affected by cirrhosis (67.7%). Alcohol was confirmed as the main etiology both as a single etiology (29.1%) and in association with other risk factors (26.9%), mainly metabolic disorders (16.2%).Tyrosine-kinase inhibitors, mainly sorafenib, were the most administered systemic treatments in first line. Patients who received at least one combination of atezolizumab and bevacizumab during the study period ( N  = 53) had a better performance status and less portal hypertension frequency than the overall population and more hepatitis B virus infection and fewer metabolic disorders as single etiology. Overall, the global health score before treatment (62.3 ±â€…21.9) was in line with that of reference cancer patients and worsened in 51.9% of the cases after first-line palliative-intent treatment. CONCLUSION: This study provided real-life data on advanced hepatocellular carcinoma characteristics and treatment patterns and described the first patients to receive the atezolizumab-bevacizumab combination before it became the new standard of care for advanced hepatocellular carcinoma.

Efficacy and Safety of Bevacizumab Combined With First-Line Chemotherapy in Elderly (≥75 Years) Patients With Metastatic Colorectal Cancer: A Real-World Study.

BACKGROUND: Although elderly patients are the first concerned by colorectal cancer (CRC), they are underrepresented in clinical trials. The real-world CASSIOPEE study was thus conducted in elderly patients treated for metastatic CRC (mCRC). METHODS: This French prospective, multicenter, noninterventional study aimed to estimate 1-year progression-free survival (PFS) and overall survival (OS), and describe treatments, patient autonomy (Instrumental Activities of Daily Living; Balducci scale), and safety over 24 months, in patients older than 75 with mCRC, starting first-line bevacizumab plus chemotherapy (NCT01555762). RESULTS: From 2012 to 2014, 402 patients were included (safety population: n = 383, efficacy population: n = 358). Patient characteristics were as follows: mean age, 81 ± 4 years (<80 years, 46%; 80-85 years, 44%; >85 years, 10%); men, 52%; colon primary tumor, 80%; main metastatic site, liver 66%; Eastern Cooperative Oncology Group performance 0-1, 81%. Median PFS was 9.1 months (95% confidence interval [CI]: 8.3-10.2). It was superior for patients ≤85 years (<80 years: 9.3 months; 80-85 years: 9.5 months) compared with patients >85 years (8.3 months). Median OS was 19.0 months (95% CI, 16.5-21.5) and decreased in the 2 oldest groups (20.6, 17.8, and 13.0 months). Autonomy assessments decreased over time leading to nonconclusive results. Twenty-six percent of patients experienced serious adverse events (SAEs): 7% bevacizumab-related SAEs, and 6% bevacizumab-targeted SAEs. Two fatal bevacizumab-related adverse events were reported (hemorrhagic stroke and intestinal ischemia). CONCLUSIONS: This large French real-world study showed that medically fit older patients with mCRC could have a benefit/risk balance similar to that of younger patients when treated with first-line bevacizumab plus chemotherapy. Improvements in geriatric assessments are needed to better define this population.

Efficacy and Safety of Two Neoadjuvant Strategies With Bevacizumab in MRI-Defined Locally Advanced T3 Resectable Rectal Cancer: Final Results of a Randomized, Noncomparative Phase 2 INOVA Study.

BACKGROUND: Recurrence and distant metastases remain a significant issue in locally advanced rectal cancer (LARC). Several multimodal strategies are assessed in clinical trials. PATIENTS AND METHODS: Patients with mid/low magnetic resonance imaging-defined high-risk LARC were randomized to arm A (12-week bevacizumab + FOLFOX-4 then bevacizumab-5-fluorouracil [5-FU]-radiotherapy [RT] before total mesorectal excision [TME]) or arm B (bevacizumab-5-FU-RT then TME). Long-term efficacy and safety up to 5 years' follow-up are reported. No comparison between arms was planned. RESULTS: Overall, 91 patients (46 in arm A and 45 in arm B) were included. Main results have been presented previously. During the late follow-up period (> 4 weeks after surgery), 4 patients (8.7%) in arm A and 4 (8.9%) in arm B experienced grade 3/4 adverse events related to bevacizumab; the most frequent were 2 anastomotic fistulas (both in arm A) and abscesses (1 in arm A and 2 in arm B). At 5 years' follow-up, 9 (19.6%) and 11 (24.4%) patients in arms A and B developed a fistula in the year after surgery, and 2 (4.3%) in arm A at > 1 year after surgery. Most resolved before study end. Five-year disease-free survival was 70% and 64.3% in arms A and B, respectively. Five-year overall survival was 90.5% (95% confidence interval, 76.7, 96.3) in arm A and 72.7% (95% confidence interval, 56.0, 83.9) in arm B. CONCLUSION: Neoadjuvant bevacizumab + FOLFOX-4 may have the potential to increase survival outcomes when followed by bevacizumab-5-FU-RT and TME in LARC. Bevacizumab-5-FU-RT then TME was associated with a higher-than-projected rate of anastomotic fistulas. Further research of neoadjuvant strategies in LARC is encouraged.
