AI Article Synopsis
- Authors found that localized bronchial carcinoma treated with radiotherapy can yield positive outcomes, showing an 8% three-year survival rate for patients treated with 50 Grays in 5 weeks.
- A comparison of two studies revealed that survival rates are higher for smaller tumors (T2) compared to larger ones, with a 3.1% survival rate for squamous cell carcinoma receiving over 40 Grays in 4 weeks.
- The study concludes that radiotherapy is most effective as an adjunct post-surgery, particularly for limited disease, and that repeating radiotherapy can improve results.
Article Abstract
Authors have shown that in some favorable cases radiotherapy of localized bronchial carcinoma could give very good results. The study on the cases from 1960 to 1969 shows that authors have 8% of three years survival upon 105 patients who have been treated by 50 Grays or more in 5 weeks. The survival was better for the small cancers T2 than for the large ones. The study on the cases from 1970 to 1977 shows that to obtain 101 cases of squamous cell carcinoma (T2,4 -N0,2 -M0) authors were obliged to study 564 cases. The three years survival was 3,1% for carcinoma receiving more than 40 Grays/4 weeks. The survival is better for small cancer and for the cases without radiological mediastinal nodes. In conclusion, radiotherapy is the best treatment after surgery, limited disease can be cure, and iterative radiotherapy increases our results.

Randomized Trial of Enhanced Versus Standard Navigation to Promote Timely Initiation of Adjuvant Radiotherapy for Head and Neck Cancer.
JCO Oncol Pract

Department of Population and Public Health Sciences, University of Southern California, Los Angeles, CA.
Purpose: National Comprehensive Cancer Network Guidelines recommend initiating postoperative radiation therapy (PORT) within 6 weeks of surgery for patients with head and neck squamous cell carcinoma (HNSCC), but delays affect 50% of patients, disproportionately burden minoritized groups, and contribute to worse oncologic outcomes. This trial evaluates the efficacy of Navigation for Disparities and Untimely Radiation thErapy (NDURE), an enhanced navigation-based intervention, relative to usual care (UC) patient navigation for starting timely PORT.
Methods: Adults with locally advanced HNSCC planning to undergo surgery and PORT were randomly assigned 1:1 to standard multidisciplinary head and neck oncology care and either NDURE, a multilevel navigation-based intervention to enhance key processes of care and overcome barriers to timely PORT, or UC, which consisted of standard patient navigation.
Endocytosis of Wnt ligands from surrounding epithelial cells positions microtubule nucleation sites at dendrite branch points.

Microtubule nucleation is important for microtubule organization in dendrites and for neuronal injury responses. The core nucleation protein, γTubulin (γTub), is localized to dendrite branch points in Drosophila sensory neurons by Wnt receptors and scaffolding proteins on endosomes. However, whether Wnt ligands are important is unknown.

Article Synopsis
- The study investigates how high glucose levels in diabetes lead to kidney cell damage through the activation of a signaling pathway involving DJ-1 and PTEN.
- DJ-1 is found to be upregulated in kidney cells under high glucose conditions, which triggers the Akt/mTORC1 signaling pathway, resulting in cell growth and fibrosis.
- The research indicates that inhibiting DJ-1 can prevent glucose-induced cell growth and damage, while overexpressing DJ-1 replicates the harmful effects, highlighting its role in renal injury related to diabetes.
Modeling the lymph node stromal cells in oral squamous cell carcinoma: insights into the stromal cues in nodal metastasis.

The study explores the development and characterization of lymph node stromal cell cultures (LNSCs) from patients with oral squamous cell carcinoma (OSCC), highlighting the importance of understanding tumor-node cross-talk for effective prognostic and therapeutic interventions. Herein, we describe the development and characterization of primary lymph node stromal cells (LNSCs, N = 14) from nodes of metastatic and non-metastatic OSCC patients. Primary cultures were established by the explant method from positive (N + ; N = 2), and negative nodes (N0; N = 4) of the metastatic patients (N = 3) as well as negative (N0; N = 8) nodes from non-metastatic (N = 4) patients.

Radiation therapy (RT) is fundamental to the fight against cancer because of its exceptional ability to target and destroy cancer cells. However, conventional radiation therapy can significantly affect the adjacent normal tissues, leading to fibrosis, inflammation, and decreased organ function. This tissue damage not only reduces the quality of life but also prevents the total elimination of cancer.
