Background: Computed tomography (CT) is the standard procedure for follow-up of non-small-cell lung cancer (NSCLC) after radiochemotherapy. CT has difficulties differentiating between tumor, atelectasis and radiation induced lung toxicity (RILT). Diffusion-weighted imaging (DWI) may enable a more accurate detection of vital tumor tissue. The aim of this study was to determine the diagnostic value of MRI versus CT in the follow-up of NSCLC.
Methods: Twelve patients with NSCLC stages I-III scheduled for radiochemotherapy were enrolled in this prospective study. CT with i.v. contrast agent and non enhanced MRI were performed before and 3, 6 and 12 months after treatment. Standardized ROIs were used to determine the apparent diffusion weighted coefficient (ADC) within the tumor. Tumor size was assessed by the longest longitudinal diameter (LD) and tumor volume on DWI and CT. RILT was assessed on a 4-point-score in breath-triggered T2-TSE and CT.
Results: There was no significant difference regarding LD and tumor volume between MRI and CT (p ≥ 0.6221, respectively p ≥ 0.25). Evaluation of RILT showed a very high correlation between MRI and CT at 3 (r = 0.8750) and 12 months (r = 0.903). Assessment of the ADC values suggested that patients with a good tumor response have higher ADC values than non-responders.
Conclusions: DWI is equivalent to CT for tumor volume determination in patients with NSCLC during follow up. The extent of RILT can be reliably determined by MRI. DWI could become a beneficial method to assess tumor response more accurately. ADC values may be useful as a prognostic marker.

Comparison between lymph and non-lymph node resection in patients with stage IA non-small-cell lung cancer: A retrospective study.
J Cancer Res Ther
December 2024
No. 2 Department of Thoracic Surgery, The Third Affiliated Hospital of Kunming Medical University, Kunming, China.
Objective: This retrospective study aimed to determine the need for lymph node resection during surgical treatment in patients with stage IA non-small-cell lung cancer (NSCLC).
Materials And Methods: A total of 1428 patients diagnosed with cT1N0M0 1 A stage NSCLC who underwent surgery were divided into two groups: lymphadenectomy (n = 1324) and nonlymphadenectomy (n = 104). The effects of lymph node resection on overall survival (OS) and recurrence-free survival (RFS) and on clinicopathological factors that affected the prognosis of the patients were investigated.
Clinical features and prognosis analysis of stage III/IV patients with lung cancer after treatment with toripalimab: A real-world retrospective.
J Cancer Res Ther
December 2024
Medical Integration and Practice Center, Cheeloo College of Medicine, Shandong University, Jinan, China.
Aim: Toripalimab is the first antitumor programmed cell death protein 1 (PD-1) antibody approved in China. For better patient management, it is important to understand the real-world outcomes of toripalimab in treating patients with lung cancer in the real world outside of clinical trials to improve patient care.
Methods: We retrospectively examined the clinical data of 80 patients with lung cancer who received the PD-1 inhibitor (toripalimab).
High-Cost Cancer Drug Use in Medicare Advantage and Traditional Medicare.
JAMA Health Forum
January 2025
Department of Health Systems, Management, and Policy, University of Colorado Cancer Center, Aurora.
Importance: Medicare Advantage (MA) plans are designed to incentivize the use of less expensive drugs through capitated payments, formulary control, and preauthorizations for certain drugs. These conditions may reduce spending on high-cost therapies for conditions such as cancer, a condition that is among the most expensive to treat.
Objective: To determine whether patients insured by MA plans receive less high-cost drugs than those insured by traditional Medicare (TM).
Endoglin as a predictive biomarker for pemetrexed sensitivity in non-small-cell lung cancer: a cellular study.
Cancer Chemother Pharmacol
January 2025
Institute of Medicine, Chung-Shan Medical University, Taichung, 40201, Taiwan.
Objective: Based on our previous research, which demonstrated that elevated plasma endoglin (ENG) levels in lung cancer patients were associated with a better prognosis, increased sensitivity to pemetrexed, and enhanced tumor suppression, this study aims to validate these findings at the cellular level. The focus is on membrane and extracellular ENG and their influence on drug response and tumor cell behavior in non-small cell lung cancer (NSCLC) cells.
Methods: The correlation between ENG expression and pemetrexed-induced cytotoxicity in eight human non-squamous subtype NSCLC cell lines was analyzed.
Efficacy and safety of first-line sintilimab plus anlotinib versus chemotherapy for metastatic non-small cell lung cancer: a phase II, open-label, randomized controlled trial.
Cancer Commun (Lond)
January 2025
Department of Respiratory and Critical Care Medicine, Chest Hospital Affiliated to Shanghai Jiao Tong University, Shanghai, P. R. China.
Background: The prognosis for non-small cell lung cancer (NSCLC) patients treated with standard platinum-based chemotherapy was suboptimal, with safety concerns. Following encouraging results from a preliminary phase I study, this phase II trial investigated the efficacy and safety of first-line sintilimab and anlotinib in metastatic NSCLC.
Methods: In this open-label, randomized controlled trial (NCT04124731), metastatic NSCLC without epithelial growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or proto-oncogene tyrosine-protein kinase ROS (ROS1) mutations, and previous treatments for metastatic disease were enrolled.
