Key Takeaway
Note higher response rates and 1-year OS for treatment-naive patients receiving camrelizumab plus apatinib in ESCC.

This meta-analysis evaluates the efficacy of camrelizumab plus apatinib for patients with advanced or metastatic esophageal squamous cell carcinoma (ESCC). The analysis synthesizes data regarding overall survival (OS), progression-free survival (PFS), and various response rates, comparing treatment-naive patients against those who were previously treated.

Key findings indicate that treatment-naive patients achieved a 95% 1-year OS compared to 55% in the pretreated group. Furthermore, the overall response rate (ORR) was significantly higher in the treatment-naive group at 87% versus 28%. Specific response metrics also favored the treatment-naive cohort: complete response rates were 22% versus 1%, and partial response rates were 64% versus 26%. The study noted that while rates of leukopenia, neutropenia, anemia, and thrombocytopenia were comparable between groups, a higher rate of hemangioma was observed in the treatment-naive group (47% vs. 12%).

The authors note that large-scale trials are warranted to validate these findings. Clinically, the combination shows promising efficacy for ESCC, particularly in treatment-naive populations where response rates and survival appear more favorable than in pretreated patients.

How this fits prior evidence

This meta-analysis addresses a gap in understanding how prior treatment status affects outcomes for camrelizumab plus apatinib in esophageal squamous cell carcinoma. While previous coverage noted that camrelizumab with etoposide and capecitabine may improve extracranial control in pulmonary choriocarcinoma, this study specifically focuses on the impact of treatment-naive status on ESCC outcomes.

Researchers analyzed data from several studies involving patients with advanced or metastatic Esophageal Squamous Cell Carcinoma (ESCC). The study looked at the effectiveness of combining two drugs, camrelizumab and apatinib, specifically comparing those who had never received prior treatment to those who had been pretreated.

The results showed that patients who were treatment-naive had a much higher one-year survival rate of 95 percent compared to 55 percent for those who were pretreated. These patients also showed significantly higher response rates and better progression-free survival. While the combination was effective, some side effects like leukopenia and anemia occurred in both groups.

Because this is a meta-analysis of several studies rather than one large trial, the findings are promising but need more validation. Larger trials are needed to confirm these results before they can change standard care. Patients should discuss these specific drug combinations and their potential benefits with their oncology team.

What this means for you:
Treatment-naive patients may see better survival rates with camrelizumab and apatinib than those previously treated.

Common questions

Who does this finding help?

This research specifically looks at patients with advanced or metastatic Esophageal Squamous Cell Carcinoma (ESCC). It highlights that those who have not received prior treatment (treatment-naive) may experience better survival rates and higher response rates when using the combination of camrelizumab and apatinib.

What are the reported side effects?

Patients receiving this combination may experience side effects such as leukopenia, neutropenia, anemia, and thrombocytopenia. The study noted that these specific rates were comparable between patients who were treatment-naive and those who had been pretreated.

How much better was the survival for new patients?

The data showed a 95 percent one-year survival rate for treatment-naive patients, compared to a 55 percent one-year survival rate for those who were pretreated. These results suggest a significant difference in outcomes based on prior treatment history.

Esophageal squamous cell carcinoma (ESCC) is a major global health burden with limited treatment options. Combining immunotherapy with antiangiogenic agents has shown promise. Camrelizumab, a PD-1 inhibitor, and apatinib, a VEGFR-2 inhibitor, offer synergistic effects, improving outcomes in patients with advanced or metastatic ESCC. A literature search was conducted across PubMed, Cochrane, Embase, Scopus, and clinicaltrials.gov from inception till May 2025. Nine studies evaluating the safety and efficacy of camrelizumab plus apatinib were included. Analysis was conducted on R Studio v4.5.0. Pooled estimates were reported as proportions and 95% CI using a random effect model. Statistical heterogeneity was assessed using I ². Subgroup analysis was based on treatment exposure. The pooled 1-year overall survival (OS) rate was 71%, with treatment-naive patients exhibiting a statistically higher 1-year OS of 95% compared with 55% in pretreated patients. One-year progression-free survival was 25%. The overall response rate was significantly higher in the treatment-naive group than in the previously treated group (87% vs. 28%). Previously treated patients showed a modest complete response rate (CRR) of 1%, while treatment-naive patients showed a significantly higher CRR of 22%. Partial response rate was significantly higher in the treatment-naive subgroup (64% vs. 26%). Hemangioma was the significant adverse event in the treatment-naive subgroup (47% vs. 12%). Rates of leukopenia, neutropenia, anemia, and thrombocytopenia were comparable between the 2 subgroups. Camrelizumab plus apatinib has shown promising efficacy with improved OS, PFS, and response rates. Large-scale trials are warranted to validate these findings and optimize treatment strategies.
