Background And Objective: The current study aimed to explore the factors influencing early progression (EP) and late progression (LP) in locally advanced rectal cancer (LARC) patients.
Methods: The patients were classified into EP and LP groups using one year as a cutoff. The random survival forest model was utilized to calculate the probability of time-to-progression.
1-nitroso-2-naphthol has thermal instability of thermal decomposition, spontaneous combustion and even explosion. Its thermal decomposition characteristics were tested by synchronous thermal analyzer (TGA/DSC); The activation energy of the thermal decomposition process was calculated by Kissinger method; The infrared absorption characteristic spectra of the gas products produced in the thermal decomposition process were measured by TGA/DSC-FTIR, and the thermal decomposition reaction process was speculated. The results show that the initial temperature (T) of TGA exothermic decomposition of 1-nitroso-2 naphthol is between 129.

In one case, we demonstrated a long-term survival after postoperative chemoradiotherapy combined with dendritic cell and cytokine-induced killer (DC-CIK) immunotherapy for pulmonary and mediastinal metastases from NPC.
Baseline Characteristics: A 53-year-old woman was admitted to our hospital in June 2008.
Article Synopsis
- The study investigates how dose distribution affects the equivalent uniform dose (EUD) model in predicting radiation-induced brain injury in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy (IMRT).
- It analyzes data from 103 patients, determining that an optimal volume-effect parameter can be found based on the max area under the curve (mAUC) from receiver operating characteristic (ROC) analyses, revealing that different volumes and dose levels influence predictive accuracy.
- The findings conclude that the volume-effect parameter in EUD varies with dose distribution, and using a critical-dose-volume EUD approach can enhance predictive capabilities compared to traditional dose/volume metrics.
Article Synopsis
- A study analyzed 221 patients with stage IA1-IIA1 cervical cancer to determine if adjuvant radiotherapy is needed after laparoscopic hysterectomy.
- Patients were divided into three groups: those receiving both surgery and radiotherapy (group A), those who had open surgery (group B), and those with laparoscopic surgery alone (group C).
- Results showed that groups A and B had significantly better 3-year local recurrence-free survival rates compared to group C, suggesting that adjuvant radiotherapy improves outcomes for early-stage cervical cancer, especially in stage IB patients.
Article Synopsis
- The study examines how half-brain delineation can help predict radiation damage in the temporal lobes of patients with nasopharyngeal carcinoma (NPC) undergoing intensity-modulated radiotherapy (IMRT).
- A retrospective analysis of 220 NPC cases showed significant differences in radiation doses received by the temporal lobes compared to half-brains, with specific dosimetric parameters demonstrating varying degrees of prediction accuracy for temporal lobe injury (TLI).
- The findings suggest that using half-brain delineation simplifies the contouring process and provides reliable estimates for TLI risk, making it a practical approach for NPC patient treatment planning.
Dysphagia is a side effect of nasopharyngeal carcinoma chemo-radiotherapy (CRT) which greatly influences the quality of life of the patients. We analyzed late dysphagia in 134 patients with nasopharyngeal cancer undergoing radical radiotherapy (RT), and correlated these findings with dose-volume histogram (DVH) parameters of the swallowing organs at risk (SWOARs). DVH parameters of SWOARs were correlated with late dysphagia, and with RTOG/EORTC scale score and the M.
