About

Hepatocellular carcinoma (HCC) carries a poor prognosis, with limited efficacy from current therapies including immune checkpoint inhibitors (ICIs). Concurrently, emotional distress (ED) is highly prevalent in cancer patients and is implicated in tumor progression via neuroendocrine-immune axis dysregulation (e.g., HPA axis activation, immunosuppressive TME). Emerging evidence, particularly from lung cancer, suggests ED may adversely impact ICI efficacy. However, its specific role and clinical significance in HCC, especially regarding ICI response, remain poorly understood.

To address this gap, we propose a large-scale, prospective, multicenter, multi-cohort study to systematically evaluate the impact of ED on treatment outcomes in HCC patients receiving immunotherapy.

Full description

To address this gap, we propose a large-scale, prospective, multicenter, multi-cohort study to systematically evaluate the impact of ED on treatment outcomes in HCC patients receiving immunotherapy.

This multi-cohort study comprises three independent cohorts:

Cohort 1: Impact of ED on first-line therapy for advanced, unresectable HCC (n=243).

In the recently published LEAP-012 study, the median progression-free survival (PFS) for advanced HCC receiving first-line transarterial chemoembolization (TACE) combined with immunotherapy and targeted therapy was 14.6 months. Based on an observed median PFS of 14.6 months for the overall population, a hazard ratio (HR) for tumor progression of approximately 1.7 for the ED group, and an estimated ED prevalence of 48.89%, we assumed exponential survival distributions for both groups. The overall survival function was constructed as:

S(t) = 0.4889 × exp(-1.7λ₀t) + 0.5111 × exp(-λ₀t) where λ₀ is the hazard rate for the non-ED group. Solving the key equation S(14.6)=0.5 numerically yields λ₀ ≈ 0.0357 per month. Consequently: Median PFS for the non-ED group = ln(2)/λ₀ ≈ 19.4 months Median PFS for the ED group = 19.4 / 1.7 ≈ 11.2 months With a two-sided alpha of 0.05, power (1-β) of 0.8, an accrual period of 12 months, and a maximum follow-up of 18 months, analysis using PASS 15 software indicated a required sample size of 194 subjects. Accounting for an estimated 20% dropout rate, a total of 243 participants will be enrolled.

Cohort 2: Impact of ED on first-line therapy for advanced, unresectable intrahepatic cholangiocarcinoma (ICC) (n=175).

In the TOPAZ-1 study, the median PFS for advanced biliary tract cancer receiving first-line chemotherapy combined with durvalumab was 12.9 months. Using the same calculation method as for Cohort 1, the estimated median PFS is approximately 9.8 months for the ED group and 17.0 months for the non-ED group. Considering the lower incidence of ICC, a longer accrual period is required. With a two-sided alpha of 0.05, power of 0.8, an accrual period of 24 months, and a maximum follow-up of 30 months, PASS 15 analysis indicated a required sample size of 140 subjects. Accounting for a 20% dropout rate, a total of 175 participants will be enrolled.

Cohort 3: Impact of ED on postoperative recurrence in resectable high-risk HCC (n=233).

In early-stage resectable HCC, patients with high-risk recurrence factors often experience early recurrence, with a reported median disease-free survival (DFS) of approximately 21.4 months. Using the same calculation method as for Cohort 1, the estimated median DFS is approximately 16.2 months for the ED group and 28.1 months for the non-ED group. With a two-sided alpha of 0.05, power of 0.8, an accrual period of 12 months, and a maximum follow-up of 24 months, PASS 15 analysis indicated a required sample size of 186 subjects. Accounting for a 20% dropout rate, a total of 233 participants will be enrolled.
