Background: Lung cancer, especially non-small cell lung cancer (NSCLC), poses a significant health challenge globally due to its high mortality. Afatinib, a second-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), has shown superior efficacy over traditional chemotherapy in NSCLC treatment. However, issues like secondary resistance and adverse effects call for alternative therapies.

Erlotinib is a necessary anticancer treatment for non-small cell lung cancer (NSCLC) patients yet it causes severe side effects such as skin rash. In this study, researchers compared the untargeted compound profiles before and after erlotinib administration to observe changes in blood metabolites in NSCLC patients. The levels of 1005 substances changed after taking erlotinib.

A 4-year prospective cohort study on patients with lung, gastric, hepatic, colorectal, breast, uterine, and ovarian cancer was conducted at the East-West Cancer Center (EWCC) of Daejeon Korean Medicine Hospital in Daejeon, Korea. We divided patients into 2 groups based on how long they had been receiving TKM oncotherapy and compared event-free survival (EFS), telomere length change, and quality of life (QoL). The study collected data on 83 patients from October 2016 to June 2020 and discovered no statistical differences in EFS based on the duration of TKM oncotherapy.

Article Synopsis
  • Chemotherapeutic agents like docetaxel can cause severe pain known as chemotherapy-induced peripheral neuropathy (CIPN), and this study focuses on how low-frequency median nerve stimulation (LFMNS) can help relieve that pain in mice.
  • Male ICR mice were given docetaxel to induce CIPN and then treated with LFMNS, with pain responses measured using specific filaments and BDNF protein levels evaluated in their nerve samples.
  • The results showed that LFMNS significantly reduced pain sensitivity and BDNF expression linked to CIPN, suggesting it could be a viable non-drug treatment for patients experiencing these symptoms.

Introduction: Although music therapy (MT) has been found to reduce anxiety in patients with cancer and delay tumour progression to some extent, its mechanism of action has not been determined. MT may reduce anxiety by reducing the concentrations of proinflammatory cytokines. The present study was designed to evaluate the effects of MT on anxiety and cytokine levels in patients with cancer.

In epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer (NSCLC), acquired resistance to EGFR tyrosine kinase inhibitors (TKI) leads to disease progression. Strategies to overcome the resistance are required in treatment for advanced lung cancer. In this study, we investigated the therapeutic effect of afatinib and HangAmDan-B1 (HAD-B1) co-administration in gefitinib-resistant NSCLC using HCC827-GR, NSCLC cell line with gefitinib resistance, and the HCC827-GR cell implanted mouse model.

Background And Objective: While there are multiple studies on the anti-tumoral effects of Panax ginseng as active ingredients (one or more ginsenosides derived from the extract) or as a whole plant extract, there is a lack of studies to assess the effects Panax ginseng's of active ingredients combined with the whole plant extract. Our aim was to study the effect of whole ginseng, enriched in the anti-tumoral Rh2 component and other ginsenosides (Ginseng Rh2+), on the metastatic capacity of non-small cell lung cancer (NSCLC).

Methods: We evaluated the effects of Ginseng Rh2+ on survival, migration and motility, induction of apoptosis, and expression of its apoptosis-related proteins in non-small cell lung cancer (NSCLC) cells in vitro and on primary tumor growth and metastatic capacity in a syngeneic mouse lung cancer model in vivo.
