Managing esophageal squamous cell carcinoma after cervical radiotherapy for a head and neck cancer: esophagectomy remains a viable option.

Managing esophageal squamous cell carcinoma (ESCC) in patients with a history of cervical radiotherapy for a head and neck cancer (HNC) often requires a careful evaluation of esophagectomy due to concerns regarding complications and prognosis. This study evaluates the periesophagectomy and oncological outcomes of such patients. Patients diagnosed with ESCC between January 2010 and August 2023 and who had undergone esophagectomy with cervical anastomosis were retrospectively reviewed.

The potential of integrating stereotactic ablative radiotherapy techniques with hyperfractionation for lung cancer.

Background: Limited literature exists on the feasibility and effectiveness of integrating stereotactic ablative radiotherapy (SABR) techniques with hyperfractionated regimens for patients with lung cancer.

Methods: We utilized the linear-quadratic model to find the optimal fraction to maximize the tumor biological equivalent dose (BED) to normal-tissue BED ratio.

Feasibility estimation of injected hydrodissection before definitive radiotherapy of pancreatic adenocarcinoma.

Background: Pancreatic adenocarcinoma is often not diagnosed until an advanced stage, and so most patients are not eligible for resection. For patients who are inoperable, definitive radiotherapy is crucial for local disease control. However, the pancreas is located close to other vulnerable gastrointestinal organs, making it challenging to deliver an adequate radiation dose.

The effect of radiotherapy on patients with pathological stage IIB breast cancer after breast-conserving surgery or mastectomy: A cohort study.

Background: Breast cancer is one of the most common cancers in women, and treatment options include surgery, systemic therapies, and radiotherapy (RT).

Skin proteomic profiling of irradiation-induced fibrosis and its modulation by low molecular weight fucoidan via tight junction pathway.

Fucoidans, sulfated and fucosylated polysaccharides extracted from brown seaweed, were found to inhibit radiotherapy-induced cell damage and fibrosis through the TGF-β1 pathway. However, the comprehensive molecular response during irradiation-induced fibrosis and fucoidan-assisted recovery still remain unclear. Rat hind limbs were irradiated and smeared with low molecular weight fucoidan (LMF).

Autophagy reprogramming stem cell pluripotency and multiple-lineage differentiation.

The cellular process responsible for the degradation of cytosolic proteins and subcellular organelles in lysosomes was termed "autophagy." This process occurs at a basal level in most tissues as part of tissue homeostasis that redounds to the regular turnover of components inside cytoplasm. The breakthrough in the autophagy field is the identification of key players in the autophagy pathway, compounded under the name "autophagy-related genes" (ATG) encoding for autophagy effector proteins.

Vertebral artery stenosis predicts cerebrovascular diseases following radiotherapy for nasopharyngeal carcinoma.

Purpose: Radiotherapy for nasopharyngeal carcinoma (NPC) may induce cerebrovascular diseases including ischemic stroke and transient ischemic attack (TIA), which can cause severe disability. However, information on the incidence and predictors of cerebrovascular diseases is scarce. This study aimed to estimate the incidence of cerebrovascular diseases following NPC, and attempts to ascertain the predictors of cerebrovascular diseases to facilitate early prevention.

Strategic Decoy Peptides Interfere with MSI1/AGO2 Interaction to Elicit Tumor Suppression Effects.

Peptide drugs that target protein-protein interactions have attracted mounting research efforts towards clinical developments over the past decades.
