Enhanced localized therapeutic precision: A face-to-face folate-targeted Cu 2+-mediated nanotherapy with thermosensitive sustained-release system. Int J Pharm 2024; 658:124213.

Abstract
Safe and effective Cu2+ supplementation in local lesion is crucial for minimizing toxicity of DSF-based chemotherapy. Targeted delivery of Cu2+ appears more promising. Intraperitoneal chemotherapy for peritoneal carcinoma (PC) establishes "face-to-face" contact between targeted nanocarriers and tumor tissue. Herein, this study developed a biodegradable, injectable thermosensitive hydrogel that coencapsulating DSF submicroemulsion (DSF-SE) and folate-modified liposome loading glycyrrhizic acid-Cu (FCDL). FCDL acted as 'beneficial horse' to target the tumor-localized folate receptor, thus liberating Cu2+ in tumor nidus. The prepared FCDL and DSF-SE were found with uniform sizes (160.2 nm, 175.4 nm), low surface charge (-25.77 mV, -16.40 mV) and high encapsulation efficiency (97.93 %, 90.08 %). In vitro drug release profile of FCDL, DSF-SE and FCDL&DSF-SE@G followed a sustained release pattern. And the release behavior of Cu2+ from FCDL was pH-related, i.e., Cu2+ was released faster under acidic condition. When FCDL and DSF-SE were loaded into an PLGA-PEG-PLGA-based hydrogel system, FCDL&DSF-SE@G was formed to ensure separated delivery of Cu2+ and DSF in space but synchronized release over time. The rheology experiment showed a satisfactory gelling temperature of 32.7 °C. In vitro cytotoxicity study demonstrated that FCDL&DSF-SE@G significantly lowered the IC50 of free Cu2+/DSF, Cu2+/DSF hydrogel and non-targeted analogue by almost 70 %, 65 % and 32 %, respectively. Accordingly, in tumor-bearing mice, FCDL&DSF-SE@G augmented the tumor inhibition rates for the same formulations by 352 %, 145 % and 44 %, respectively. The main mechanism was attributed to higher uptake of FCDL and DSF-SE, resulting in increased Cu(DDTC)2 formation, ROS production and cell apoptosis. In conclusion, this targeted nanotherapy approach with dual-nanocarriers loaded hydrogel system, with its focus on face-to-face contact between nanocarriers and tumor tissues in the peritoneal cavity, holds significant promise for intraperitoneal chemotherapy in PC.

Abstract
OBJECTIVES Development and validation of a predictive model including serum vitamin concentration to estimate the risk of chemotherapy-induced grade 3/4 neutropenia in esophageal cancer, gastric cancer, or colorectal cancer patients who receive the first cycle of chemotherapy. METHODS Data from 535 patients treated at the Affiliated Fuyang People's Hospital of Anhui Medical University from January 1, 2020, to March 2, 2022, were used to derive the predictive model. Least absolute shrinkage and selection operator regression analysis was performed to screen potential risk characteristics, and multivariate logistic regression was utilized to investigate efficient factors associated with chemotherapy-induced neutropenia. A nomogram was constructed using this logistic model. This nomogram was then tested on a temporal validation cohort containing 212 consecutive patients. RESULTS In the cohort of all 747 eligible patients, grade 3/4 neutropenia incidence was 45.2%. Age, Eastern Cooperative Oncology Group-performance status, neutrophil count, serum albumin, and hemoglobin data were entered into the final model. The performance of the final predictive nomogram was assessed by the area under the receiver operating characteristic curve in both the development and validation datasets. The calibration curves indicated that the estimated risks were accurate. Decision curve analysis for the predictive model exhibited improved clinical practicality. CONCLUSION In the present study, we established an accessible risk predictive model and identified valuable serum vitamin concentration parameters associated with chemotherapy-induced neutropenia. The predictive model may improve the grade 3/4 neutropenia risk prediction in patients with gastrointestinal malignancies who receive oxaliplatin- and fluoropyrimidine-based chemotherapy and help physicians make appropriate decisions for disease management.

Cumulative total S-1 dose in adjuvant chemotherapy affects the long-term outcome following curative gastrectomy for gastric cancer. Am J Cancer Res 2021; 11:2312-2318. [PMID: 34094687 PMCID: PMC8167698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 03/07/2021] [Indexed: 06/12/2023] Open
Abstract
A recent JCOG1104, OPAS-1 trial revealed the significance of S-1 duration. However, the significance of cumulative total S-1 dose (CTSD) remains unclear. In this study, we designed to evaluate the prognostic effect of CTSD on adjuvant chemotherapy after curative gastrectomy. We retrospectively analyzed 77 consecutive pStage II and III gastric cancer (GC) patients, who underwent curative gastrectomy followed by adjuvant S-1 chemotherapy from 2008 through 2014. CTSD of 20000 mg was the upper-limit of cut-off value to stratify the prognosis (5-year relapse free survival (RFS); CTSD < 20000 mg vs. CTSD ≥ 20000 mg: 51.9% vs. 85.1%, P = 0.004). Compared patients with CTSD more than 20000 mg, those with CTSD less than 20000 mg had a significantly higher rate of preoperative anemia (P = 0.041), low nutrition (P = 0.008) and open gastrectomy (P = 0.012). Multivariate Cox's proportional hazards model for RFS proved that CTSD less than 20000 mg was an independent prognostic factor [P = 0.031, HR 3.32 (95% CI: 1.11-11.1)] although S-1 intensity and duration were not independent prognostic factors. The cumulative total S-1 dose more than 20000 mg might contribute to better prognosis.
