Plenty of studies have demonstrated the prognostic value of various inflammation-based indexes in cancer. This study was designed to investigate the prognostic value of the C-reactive protein/albumin (CRP/Alb) ratio in esophageal squamous cell carcinoma. A retrospective study of 423 cases with newly diagnosed esophageal squamous cell carcinoma was conducted. We analyzed the association of the CRP/Alb ratio with clinicopathologic characteristics. The prognostic value was explored by univariate and multivariate survival analysis. In addition, we compared the discriminatory ability of the CRP/Alb ratio with other inflammation-based prognostic scores by evaluating the area under the receiver operating characteristics curves (AUC), including the modified Glasgow Prognostic Score (mGPS), neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR). The optimal cut-off value was identified to be 0.095 for the CRP/Alb ratio. A higher level of the CRP/Alb ratio was associated with larger tumor size (P < 0.001), poorer differentiation (P = 0.019), deeper tumor invasion (P = 0.003), more lymph node metastasis (P = 0.015), more distant metastasis (P < 0.001) and later TNM stage (P < 0.001). The CRP/Alb ratio was identified to be the only inflammation-based prognostic score with independent association with overall survival by multivariate analysis (P = 0.031). The AUC value of the CRP/Alb ratio was higher compared with the NLR and PLR, but not mGPS at 6, 12 and 24 months of follow-up. In addition, the CRP/Alb ratio could identify a group of patients with mGPS score of 0 who had comparable overall survival with those with mGPS score of 1. The CRP/Alb ratio is a novel but promising inflammation-based prognostic score in esophageal squamous cell carcinoma. It is a valuable coadjutant for the mGPS to further identify patients’ survival differences.

Lauren-classification and human epidermal growth factor receptor 2 (HER2) status are two important pathological features of gastric cancer patients. The prognostic value of HER2 in gastric cancer remains controversial. Intestinal type gastric cancer has better prognosis and higher HER2 positive proportion. What is the interaction between these two factors? We hypothesized that a combination of Lauren-classification and human epidermal growth factor receptor 2 (HER2) status (L-H status) might be more meaningful than either factor alone.

Different clinical trials for advanced esophageal cancer have investigated diverse immuno-oncology combinational treatment in first-line setting, but the optimal choice has not been identified. We used PubMed, Embase, and Cochrane Library databases for systematic retrieval. The primary endpoint was overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and treatment-related adverse events (AEs) between immune checkpoint inhibitors combined with chemotherapy and chemotherapy. A total of five phase-III randomized controlled trials involving 3,163 patients met the inclusion criteria. Significantly improved OS (HR: 0.69, 95% CI: 0.62-0.76, P＜0.001), PFS (HR: 0.62, 95% CI: 0.55-0.70, P < 0.001) and ORR (RR: 1.41, 95% CI: 1.23-1.62, P＜0.001) were observed when programmed death 1 (PD-1) inhibitor was added to chemotherapy. Toripalimab plus chemotherapy achieved the best OS benefit than any other treatment examined (HR: 0.58, 95% CI: 0.43-0.78). The longest PFS was founded in both sintilimab-chemotherapy and camrelizumab-chemotherapy combination (HR: 0.56, 95% CI: 0.46-0.68). Patients treated with nivolumab-chemotherapy got the best ORR improvement as compared to other combinations (RR: 1.73, 95% CI:1.40-2.14). Camrelizumab-chemotherapy and pembrolizumab-chemotherapy caused a relatively lower incidence of grade ≥ 3 AEs than other immunotherapy combination regimens. Subgroup analyses suggested significant OS advantage in programmed death-ligand 1(PD-L1) tumor-positive score (TPS) ≥ 10% groups and obviously longer PFS in PD-L1 combined positive score (CPS) ≥ 10 groups. In advanced esophageal cancer, PD-1 inhibitors combined with chemotherapy as first-line therapy have better survival outcomes than chemotherapy with greater but manageable toxicity. Toripalimab-chemotherapy showed the best OS benefit over chemotherapy, while sintilimab-chemotherapy and camrelizumab-chemotherapy generated the best PFS. The highest ORR improvement was founded in patients receiving nivolumab plus chemotherapy.

Background: Nivolumab plus ipilimumab (N‐I) or pembrolizumab (PEM) is associated with survival improvement as chemotherapy‐free, first‐line treatment for patients with advanced non‐small cell lung carcinoma (NSCLC) and positive programmed cell death ligand 1 (PD‐L1). However, no direct comparison data exist between these two regimens to inform clinical decisions. Therefore, we performed indirect comparison for N‐I versus PEM using frequentist methods.Results: Three randomized trials (KEYNOTE‐024, KEYNOTE‐042, and CheckMate 227) involving 2372 patients were included. For patients with tumor PD‐L1 level of ≥1%, pooled meta‐analyses showed that both N‐I and PEM improved overall survival (OS) relative to chemotherapy (N‐I: hazard ratio [HR] 0.82, 95% CI 0.69‐0.97; PEM: HR 0.81, 95% CI 0.71‐0.93); whereas only N‐I significantly improved progression‐free survival (PFS) (N‐I: HR 0.79, 95% CI 0.65‐0.96; PEM: HR 1.07, 95% CI 0.94‐1.21). Neither N‐I nor PEM was associated with improved objective response rate (ORR) compared with chemotherapy (N‐I: relative risk [RR] 1.20, 95% CI 0.98‐1.46; PEM: RR 1.03, 95% CI 0.86‐1.23). Indirect comparisons showed that N‐I was associated with longer PFS than PEM (HR 0.77, 95% CI 0.62‐0.95). However, N‐I was not superior to PEM in terms of OS (HR 0.98, 95% CI 0.77‐1.24) and ORR (RR 1.17, 95% CI 0.89‐1.52). N‐I showed a less favorable toxicity profile relative to PEM (all grade adverse events: RR 1.28, 95% CI 1.17‐1.40).Conclusions: N‐I and PEM provide comparable OS benefit for PD‐L1‐positive NSCLC. N‐I further improves PFS relative to PEM but at meaningful cost of toxicities.

Background: In October 2015, China’s one-child policy was universally replaced by a so-called two-child policy. This study investigated the association between the enactment of the new policy and changes in the number of births, and health-related birth outcomes.Methods: We used difference-in-difference model to analyse the birth record data in Pudong New Area, Shanghai.The design is descriptive before-and-after comparative study.Results: The data covered three policy periods: the one-child policy period (January 2008 to November 2014); the partial two-child policy period (December 2014 to June 2016); the universal two-child policy period (July 2016 to December 2017). There was an estimate of 7656 additional births during the 18 months of the implementation of the universal two-child policy. The trend of monthly percentage of births to mothers aged ≥35 increased by 0.24 percentage points (95% confidence interval 0.19 to 0.28,p < 0.001) during the same period. Being a baby boy, preterm birth, low birth weight, parents with lower educational attainment, and assisted delivery were associated with a higher risk of birth defects.Conclusions: The universal two-child policy was associated with an increase in the number of births and maternal age. Preterm birth, low birth weight, and assisted delivery were associated with a higher risk of birth defects, which suggested that these infants needed additional attention in the future.
