The targeted nanoagents have shown great potential clinically for cancer therapy. Traditional targeted nanodrugs are usually prepared through surface postmodification. Herein, a nanodrug is self-assembled from the amphiphilic precursor of targeting peptide RGD conjugated with cytotoxin epothilone B (Epo B) through a linker containing the thioketal (tk) group that is sensitive to reactive oxygen species (ROS). The obtained RGD-tk-Epo B conjugate nanoparticles (RECNs) are stable and uniform, which facilitates improving tumor-targeting capacity and accumulation of the drug because of the large number of RGD on the surface of the RECN. After internalization by cancer cells, the blood-inert tk group between RGD and Epo B can be cleaved in the presence of high level of ROS to release Epo B, exhibiting a markedly tumor selectivity and excellent anticancer efficiency and .

Purpose: The management of soft tissue sarcoma (STS) at reference centers with specialized multidisciplinary tumor boards (MTB) improves patient survival. The German Cancer Society (DKG) certifies sarcoma centers in German-speaking countries, promoting high standards of care. This study investigated the variability in treatment recommendations for localized STS across different German-speaking tertiary sarcoma centers.

The prominence of circular RNAs (circRNAs) has surged in cancer research due to their distinctive properties and impact on cancer development. This review delves into the role of circRNAs in four key cancer types: colorectal cancer (CRC), gastric cancer (GC), liver cancer (HCC), and lung cancer (LUAD). The focus lies on their potential as cancer biomarkers and drug targets.

Objective: The purpose of this study is to analyze the predictive value of neutrophil to lymphocyte ratio (NLR), lymphocyte count to monocyte count ratio (LMR), platelet to lymphocyte ratio (PLR), platelet count multiplied by neutrophil count to lymphocyte count ratio (SII), red blood cell distribution width (RDW), packed cell volume (PCV), and plateletcrit (PCT) levels in advanced non-small cell lung cancer (NSCLC) patients treated with PD-1/PD-L1 inhibitors.
Materials And Methods: From March 2019 to August 2023, we screened 104 of 153 patients with stage III unresectable local advanced NSCLC and IV NSCLC who received PD-1/PD-L1 inhibitor therapy at our hospital and met the inclusion and exclusion criteria for analysis. All patients were collected for clinical information, including baseline blood indicator (NLR, PLR, LMR, SII, CRP, RDW, PCV and PCT) levels before PD-1/PD-L1 inhibitor therapy and blood indicator levels and imaging evaluation results every two cycles after PD-1/PD-L1 inhibitor therapy.
Lymph-node ratio as a risk factor for recurrence following neoadjuvant docetaxel, cisplatin, and 5-fluorouracil therapy for locally advanced esophageal squamous cell carcinoma.

Department of Gastroenterological Chemotherapy, Japanese Foundation for Cancer Research, Cancer Institute Hospital, 3-8-31 Ariake, Koto-Ku, Tokyo, 135-8550, Japan.
Background And Purpose: It remains unclear whether the lymph-node ratio (LNR) is a relevant factor for the risk of recurrence following neoadjuvant chemotherapy (nCT) with docetaxel, cisplatin, and 5-fluorouracil (DCF), which is a new standard of care for locally advanced esophageal squamous cell carcinoma (ESCC) in Japan. This study aimed to evaluate the clinical utility of LNR as a risk factor for recurrence.
Materials And Methods: We retrospectively analyzed 75 patients who underwent nCT-DCF followed by curative surgery for resectable ESCC.

Objective: To compare the treatment of osteoradionecrosis (ORN) using a protocol that incorporates antimicrobial photodynamic therapy with a conventional treatment protocol.
Methodology: This retrospective study analyzed 55 patients diagnosed with ORN at a reference hospital between 2002 and 2021. Patients were treated using two different clinical protocols.
