Summary: This study aims to identify immune-related prognostic factors for nasopharyngeal carcinoma (NPC) after radiotherapy and establish a prognostic model for predicting progression-free survival (PFS) and distant metastasis-free survival (DMFS). The study collected clinical information and investigated immune cells, EBV DNA and cytokines from NPC patients. Cox regression and LASSO regression were used to screen the prognostic factors and build nomograms. The results were also validated in a separate set of patients.

Summary: The study found that smoking has a negative impact on the prognosis of patients with nasopharyngeal carcinoma (NPC), with a dose-dependent effect on survival outcomes. Furthermore, the combination of cumulative smoking consumption and pre-treatment EBV DNA levels was identified as an independent predictor of poor prognosis in male NPC.

Summary: In this study, ctDNA was identified as a robust biomarker for early detection of disease progression and prognosis stratification after RT/CRT in ESCC. Detectable ctDNA at week 4 of RT/CRT might indicate higher local recurrence risks, implying the potential clinical utility of ctDNA tests in guiding post-RT/CRT treatments for locoregional control in ESCC.

Summary: The study identified Angiogenin (ANG) as a potential molecular marker for predicting tumor recurrence and progression in nasopharyngeal carcinoma (NPC) patients. Increased expression of ANG was associated with radioresistance and poor prognosis in NPC. A nomogram model based on ANG expression was developed to predict overall survival in NPC patients.

Summary: Radiotherapy is crucial for nasopharyngeal carcinoma patients, with a typical treatment duration of six to six and a half weeks. Prolonged radiotherapy duration is associated with higher risk of distant metastasis and death, highlighting the importance of avoiding prolonged treatment to improve outcomes.

Summary: MiR-483-5p is highly expressed in NPC and is associated with poor prognosis of NPC patients. Inhibiting its expression can suppress the migration and invasion of NPC cells, with its target identified as EGR3, the downregulation of which enhances the migration and invasion capacities of NPC cells.

Summary: Local radiotherapy to metastatic lesions might be a protective factor for patients with metastatic nasopharyngeal carcinoma (mNPC) as shown in the study involving 109 patients with mNPC. The overall survival rates were significantly higher in patients who received local radiotherapy compared to those who did not receive radiotherapy to metastatic lesions.

Summary: This study aimed to investigate the clinical characteristics and prognosis of nasopharyngeal carcinoma (NPC) in children and adolescents of different age groups. The results showed that the diagnosis in the children group relied on endoscopic biopsy and neck mass biopsy, with a higher proportion of keratinizing squamous cell carcinoma. The number of cases receiving induction chemotherapy and concurrent chemoradiotherapy in the children group was lower compared to the adolescent group, and the proportion of radiotherapy in the upper and lower cervical lymph node drainage areas was also lower in the children group. Therefore, it is important to improve the understanding of the clinical characteristics of children with NPC and implement appropriate treatment strategies.

Summary: By analyzing data from non-metastatic NPC patients, N2-3 or T4 patients were identified as ideal candidates for multicenter clinical trials in locoregionally advanced NPC. Stratification based on pre-treatment EBV DNA can identify high-risk patients, while detectable post-treatment EBV DNA indicates a high risk of progression.

Summary: The combination of cisplatin-based induction or adjuvant chemotherapy with concurrent chemoradiotherapy has been found to improve overall survival in patients with locoregionally advanced nasopharyngeal carcinoma. The optimal platinum doses for the concurrent and induction/adjuvant phases were determined to be 160 mg/m(2) and 260 mg/m(2) respectively.

Summary: This study evaluated the impact of material assignment in the nasal cavity on dose calculation for nasopharyngeal carcinoma treatment using the Acuros XB algorithm. The results showed that assigning the nasal cavity to the lung instead of air resulted in higher calculated doses. This could potentially lead to underdosing of the target volumes, highlighting the importance of accurate material assignment in dose calculation.

Summary: Recent studies have highlighted the presence of a substantial amount of analyzable long cell-free DNA (cfDNA) in plasma through single molecule, real-time (SMRT) sequencing. In this study, the size biases of SMRT sequencing by PacBio and nanopore sequencing by ONT were evaluated. The results showed that both platforms had biases towards sequencing longer DNA fragments, with PacBio showing a stronger bias. Tissue-of-origin analysis based on single-molecule methylation patterns performed comparably on both platforms. It is important to be aware of the analytical characteristics and biases of the sequencing platforms used when analyzing the size and end motif of cfDNA.

Summary: The study investigated the effects of magnetic field gradients on dose deposition in an inhomogeneous medium and demonstrated the benefits of magnetic-field-modulated radiotherapy (MagMRT) under multiple radiation beams. Monte Carlo simulations showed that the magnitudes of dose enhancement and reduction induced by the magnetic field gradients were more prominent in lower density mediums. MagMRT induced dose enhancement at the iso-center and dose reduction in regions around the tumor when multiple radiation beams were used. Optimized magnetic field gradients in MagMRT resulted in a sharper dose fall-off in all directions outside the target volume, providing a better sparing to the surrounding normal tissue.

Summary: A meeting of experts in November 2021 discussed the performance and cost-effectiveness of EBV-based approaches for screening early stage nasopharyngeal carcinoma. Both serum EBV antibody and plasma EBV DNA testing methods were found to be favorable. Additionally, the use of MRI was recommended to increase the sensitivity of NPC detection without greatly impacting the cost-effectiveness of the screening program.

Summary: Peptides/small proteins encoded by noncanonical open reading frames (ORF) of previously claimed non-coding RNAs have important biological functions but are largely uncharacterized. In this study, we identified and validated a small protein SP0495 as a novel tumor suppressor, frequently inactivated by promoter methylation in multiple tumors. SP0495 functions as a phosphoinositide-binding protein, regulating AKT signaling activation and autophagy. It inhibits tumor cell growth and induces apoptosis, cell cycle arrest, senescence, and autophagy through multiple mechanisms, including the modulation of phosphoinositides turnover and autophagic/proteasomal degradation of autophagy regulators. SP0495 has the potential to be a biomarker for cancer diagnosis and prognosis.

Summary: Post-radiotherapy clearance of plasma EBV DNA is associated with prognosis in NPC patients. T cells, particularly CD8+ T cells expressing CCR1, 4 and/or 5, play a role in this clearance process. Differences in chemo-attractants related to T-cell chemotaxis are also linked to clinical outcome. Validation in larger cohorts is needed to confirm these findings.

Summary: The study aimed to assess the long-term toxic effects and clinical outcomes associated with adding bevacizumab, a vascular endothelial growth factor inhibitor, to standard chemoradiation for patients with nasopharyngeal carcinoma (NPC). The results showed favorable long-term outcomes and no severe adverse events when using bevacizumab in combination with chemoradiation. Further investigation may be warranted.

Summary: Liquid biopsy using cell-free DNA (cfDNA) has gained global interest as a molecular diagnostic tool. Recent studies have discovered long cfDNA in the plasma of pregnant women and cancer patients, opening up a new avenue of long cfDNA-based liquid biopsy. This review summarizes the current knowledge in this nascent field of long cfDNA analysis, focusing on its fragmentomic and epigenetic features. Long-read sequencing enables single-molecule methylation analysis, which has promising clinical potential in prenatal and cancer testing. The limitations hindering the immediate clinical applications of long cfDNA analysis and the efforts to address them are also discussed. With concerted efforts, long cfDNA analysis is expected to contribute to the expanding armamentarium of liquid biopsy.
