Molecular and Immune Correlates of Response to First-Line De-escalated Chemotherapy plus Penpulimab and Anlotinib in Advanced Cervical Cancer

Abstract The standard of care for advanced cervical cancer includes chemotherapy, antiangiogenic, and/or immune checkpoint blockade regimens. Although effective, it leads to pleiotropic side effects. Deescalation chemotherapy together with immunotargeted therapies has been proven effective and less toxic in other cancers. In this study, we conducted a multicenter, single-arm, phase II study of first-line deescalated platinum-based chemotherapy plus anlotinib and penpulimab, followed by maintenance therapy solely with anlotinib and penpulimab in patients with PD-L1–positive, persistent, recurrent, or metastatic cervical cancer. Of 32 efficacy-evaluable patients, 30 (93.8%, 95% confidence interval, 79.2%–99.2%) had an investigator-confirmed objective response. Single-nucleus RNA sequencing implied enhanced chemotaxis and proliferative activity of tumor-infiltrating T cells, and activated germinal center B cells portended optimal treatment response. Patients with a high tertiary lymphoid structure-to-tumor area ratio exhibited better survival. Our findings lay the groundwork for the feasibility of first-line de-escalated chemotherapy plus anlotinib and penpulimab in patients with metastatic, persistent, or recurrent cervical cancer. Significance: We recruited 34 patients with advanced cervical cancer receiving two cycles of platinum-based chemotherapy plus anlotinib and penpulimab, followed by maintenance therapy solely with anlotinib and penpulimab, and showed safety and efficacy of this deescalation regimen. This work highlights the potential for personalized treatment strategies and feasibility of reduced-toxicity regimens.

Comprehensive clinical analysis of gastric-type endocervical adenocarcinoma: a real-world multicenter study

Gastric-type endocervical adenocarcinoma (G-EAC) is a rare malignancy, and its clinicopathological characteristics remain poorly defined. This study aimed to evaluate the real-world features, treatment patterns, and outcomes of patients with G-EAC. Clinical data from 124 patients diagnosed with G-EAC between 2012 and 2024 across four tertiary hospitals in China were retrospectively analyzed. Clinicopathological features, therapeutic approaches, and survival outcomes were assessed. Overall survival (OS) was the primary endpoint. Kaplan-Meier and Cox regression analyses were performed to identify prognostic factors. The median diagnostic age was 55 years (range, 33-82). At presentation, 62.1% of patients had invasion or metastasis, most commonly lymphovascular (47.6%). Surgery was performed in 81.5% of cases, and 84.7% received chemotherapy, primarily platinum-based (81.5%). Radiotherapy was administered to 69.4%. The 1-, 3-, and 5-year OS rates were 78.6%, 54.8%, and 46.1%, respectively. Older age (≥65 years; HR, 4.71; 95% CI, 1.52-14.58; G-EAC exhibits aggressive behavior and unfavorable prognosis, with a 5-year OS of 46.1%. Multimodal treatment, particularly surgery combined with chemotherapy, remains the cornerstone of management and may improve survival. Prospective multicenter studies are warranted to further define optimal therapeutic strategies for this rare entity.
