Diagnostic work-up and systemic treatment for advanced non-squamous non-small-cell lung cancer in four Southeast Asian countries.

BACKGROUND: Lung cancer is the second most common cancer and leading cause of cancer mortality worldwide. Recent advances in molecular testing and targeted therapy have improved survival among patients with metastatic non-small-cell lung cancer (NSCLC). We sought to quantify and describe molecular testing among metastatic non-squamous NSCLC cases in selected Southeast Asian countries and describe first-line therapy chosen. PATIENTS AND METHODS: A retrospective study was conducted based on incident lung cancer cases diagnosed between 2017 and 2019 in Lampang (Thailand), Penang (Malaysia), Singapore and Yogyakarta (Indonesia). Cases (n = 3413) were defined using the International Classification of Diseases for Oncology third edition. In Singapore, a clinical series obtained from the National Cancer Centre was used to identify patients, while corresponding population-based cancer registries were used elsewhere. Tumor and clinical information were abstracted by chart review according to a predefined study protocol. Molecular testing of epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK) gene rearrangement, ROS1 gene rearrangement and BRAF V600 mutation was recorded. RESULTS: Among 2962 cases with a specified pathological diagnosis (86.8%), most patients had non-squamous NSCLC (75.8%). For cases with staging information (92.1%), the majority presented with metastatic disease (71.3%). Overall, molecular testing rates in the 1528 patients with stage IV non-squamous NSCLC were 67.0% for EGFR, 42.3% for ALK, 39.1% for ROS1, 7.8% for BRAF and 36.1% for PD-L1. Among these patients, first-line systemic treatment included chemotherapy (25.9%), targeted therapy (35.6%) and immunotherapy (5.9%), with 31% of patients having no record of antitumor treatment. Molecular testing and the proportion of patients receiving treatment were highly heterogenous between the regions. CONCLUSIONS: This first analysis of data from a clinically annotated registry for lung cancer from four settings in Southeast Asia has demonstrated the feasibility of integrating clinical data within population-based cancer registries. Our study results identify areas where further development could improve patient access to optimal treatment.

Family stability during childhood and the risk to develop hypertensive diseases in pregnancy.

BACKGROUND: Parental care giving, divorce and death are associated with physical health as an adult. AIM: To investigate whether the structure of the nuclear family during childhood shows any correlation with the development of hypertensive diseases in pregnancy as an adult. STUDY DESIGN: Self-administered questionnaires were sent to 2600 women with hypertensive diseases in pregnancy and to 1484 controls. SUBJECTS: After confirmation of the diagnosis data from 842 patients and 623 control women were evaluated. OUTCOME MEASURES: Type, number and involvement of different caregivers, parental separation, parental death. RESULTS: In both groups parental separation and parental death were found equally often. In all age groups during childhood fathers were involved significantly less often in care giving when women with hypertensive disorders in pregnancy were compared to control women (1st-3rd year 23.4%/17%, <0.0001; 4th-10th year 25.7%/19.3%, <0.0001; 11th-18th year 30.1%/23.9%, <0.0001). The total number of caregivers involved was significantly higher in patients. CONCLUSIONS: The quality of parental care giving, i.e. the involvement of fathers and the total number of caregivers correlate with the risk to develop HDP. Further research is needed to specify underlying mechanisms and the relevant factors of the parent-child relationship.
