  • Genotype-phenotype mapping of a patient-derived lung cancer organoid biobank identifies NKX2-1-defined Wnt dependency in lung adenocarcinoma

    Ebisudani T., Hamamoto J., Togasaki K., Mitsuishi A., Sugihara K., Shinozaki T., Fukushima T., Kawasaki K., Seino T., Oda M., Hanyu H., Toshimitsu K., Emoto K., Hayashi Y., Asakura K., Johnson T.A., Terai H., Ikemura S., Kawada I., Ishii M., Hishida T., Asamura H., Soejima K., Nakagawa H., Fujii M., Fukunaga K., Yasuda H., Sato T.

     View Summary

    Human lung cancer is a constellation of tumors with various histological and molecular properties. To build a preclinical platform that covers this broad disease spectrum, we obtained lung cancer specimens from multiple sources, including sputum and circulating tumor cells, and generated a living biobank consisting of 43 lines of patient-derived lung cancer organoids. The organoids recapitulated the histological and molecular hallmarks of the original tumors. Phenotypic screening of niche factor dependency revealed that EGFR mutations in lung adenocarcinoma are associated with the independence from Wnt ligands. Gene engineering of alveolar organoids reveals that constitutive activation of EGFR-RAS signaling provides Wnt independence. Loss of the alveolar identity gene NKX2-1 confers Wnt dependency, regardless of EGFR signal mutation. Sensitivity to Wnt-targeting therapy can be stratified by the expression status of NKX2-1. Our results highlight the potential of phenotype-driven organoid screening and engineering for the fabrication of therapeutic strategies to combat cancer.

     View Summary

    Background: Potential novel strategies for adverse event (AE) management of osimertinib therapy, including therapeutic drug monitoring and the use of biomarkers, have not yet been fully investigated. This study aimed to evaluate (1) the relationship between exposure to osimertinib, especially its active metabolites (AZ5104 and AZ7550), and AEs, and (2) the relationship between germline polymorphisms and AEs. Methods: We conducted a prospective, longitudinal observational study of 53 patients with advanced non-small cell lung cancer receiving osimertinib therapy from February 2019 to April 2022. A population pharmacokinetic model was developed to estimate the area under the serum concentration–time curve from 0 to 24 h (AUC0–24) of osimertinib and its metabolites. Germline polymorphisms were analyzed using TaqMan® SNP genotyping and CycleavePCR® assays. Results: There was a significant association between the AUC0–24 of AZ7550 and grade ≥ 2 paronychia (p = 0.043) or anorexia (p = 0.011) and between that of osimertinib or AZ5104 and grade ≥ 2 diarrhea (p = 0.026 and p = 0.049, respectively). Furthermore, the AUC0–24 of AZ5104 was significantly associated with any grade ≥ 2 AEs (p = 0.046). EGFR rs2293348 and rs4947492 were associated with severe AEs (p = 0.019 and p = 0.050, respectively), and ABCG2 rs2231137 and ABCB1 rs1128503 were associated with grade ≥ 2 AEs (p = 0.008 and p = 0.038, respectively). Conclusion: Higher exposures to osimertinib, AZ5104, and AZ7550 and polymorphisms in EGFR, ABCG2, and ABCB1 were related to higher severity of AEs; therefore, monitoring these may be beneficial for osimertinib AE management.

     View Summary

    PURPOSE:Patients' values and priorities in their lives should be appreciated from an early phase of incurable diseases such as advanced cancer. However, studies examining these characteristics have been lacking. This study attempted to determine what patients with advanced lung cancer valued most, once they had been diagnosed, and any associated factors.METHODS:Patients with newly diagnosed advanced lung cancer (N = 248) were enrolled in a questionnaire survey conducted at 16 hospitals in Japan. Their priorities were assessed using a free-text response to the question what is the most important thing to you now? at the time of diagnosis and 3 months after diagnosis. The free-text responses were classified into 10 categories for quantification. The clinical characteristics associated with the category describing daily life were further examined.RESULTS:Free-text comments were obtained from 103 (44.0%) and 66 (42.6%) patients at the time of diagnosis and at 3 months, respectively. The most frequent categories were family (at diagnosis: 50.5%; at 3 months: 50.0%) and daily life (at diagnosis: 33.0%; at 3 months: 36.4%), followed by health (at diagnosis: 32.0%; at 3 months: 27.3%) at both time points. The patients mentioning daily life, the issues related to how to spend daily life, showed significantly higher total scores and functional well-being subscale scores on the Functional Assessment of Cancer Therapy-Lung scale at both time points and lower depression scores at diagnosis and lower anxiety scores at 3 months on the Hospital Anxiety and Depression Scale.CONCLUSION:Family and daily life were highly valued by patients with advanced lung cancer at diagnosis. A better quality of life and better mood were associated with mentioning daily life, which should be taken into account in care planning to maintain patients' involvement in daily life even with incurable diseases.

  • Real-world clinical practice for advanced non-small-cell lung cancer in the very elderly: A retrospective multicenter analysis

     View Summary

    Background: The optimal treatment for advanced non-small cell lung cancer (NSCLC) in very elderly patients is unclear. We aimed to evaluate their treatment in real-world clinical practice and identify suitable therapy that can improve their prognosis. Materials and methods: The medical records of 132 Japanese patients aged 80 years and older with advanced NSCLCs who were enrolled at a university hospital and its 9 affiliates were retrospectively analyzed. Clinical characteristics and overall survival (OS) were compared based on the Eastern Cooperative Oncology Group Performance Status (ECOG PS) and biomarker statuses. Patients were defined as biomarker-positive if programmed death-ligand 1 tumor proportion score (PD-L1 TPS) was ≥ 50% or activating mutations were present in epidermal growth factor receptor, anaplastic lymphoma kinase, or c-ros oncogene 1. Finally, the factors contributing to better prognosis were explored in both PS 0 - 2 and PS 3 - 4 patient groups. Results: The PS 0 - 2 patients showed a longer median OS than the PS 3 - 4 patients (5.5 vs. 1.6 months). PS 0 - 2 patients with positive biomarkers who received chemotherapy showed a significantly longer median OS than those without (18.1 vs. 3.7 months). Among the biomarker-negative/unknown PS 0 - 2 patients, the median OS showed no significant difference between those who received chemotherapy and those who did not (4.5 vs. 3.1 months). The multivariate analysis showed that treatment with tyrosine kinase inhibitors or immune checkpoint inhibitors was related to better prognoses in the PS 0 - 2 group. Conclusion: Biomarker-matched therapy is effective even in very elderly patients. Meanwhile, the effectiveness of chemotherapy for biomarker-negative/unknown PS 0 - 2 patients is questionable.

     View Summary

    We report the first case of a patient with non-small cell lung cancer (NSCLC) with malignant pleural effusion (MPE) who achieved disease-and treatment-free survival for nearly 10 years. A 50-year-old man was diagnosed with NSCLC with MPE and underwent chemotherapy and salvage thoracic surgery. The patient received chemotherapy with cisplatin, pemetrexed, and bevacizumab, and a partial response was achieved. After informed consent was obtained from the patient, right middle lobectomy was performed to achieve local tumor control. Postoperative adjuvant chemotherapy with pemetrexed and bevacizumab was discontinued after almost 1 year of chemotherapy due to side effects such as diarrhea and muscle weakness. The patient has survived without recurrence of lung cancer for more than 11 years after being diagnosed and nearly 10 years after discontinuing chemotherapy.
