Abstract
For patients with central nervous system (CNS) malignancies, liquid biopsies of the cerebrospinal fluid (CSF) may offer an unparalleled source of information about the tumor, with much less risk than traditional biopsies. Two techniques have been adapted to CSF in clinical settings: circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA). CTCs have been employed mostly as a diagnostic tool for leptomeningeal metastases in epithelial tumors, although they may also have value in the prognostication and monitoring of this disease. The ctDNA technology has been studied in a variety of primary and metastatic brain and spinal cord tumors, where it can be used for diagnosis and molecular classification, with some work suggesting that it may also be useful for longitudinal tracking of tumor evolution or as a marker of residual disease. This review summarizes recent publications on the use of these two tests in CSF, focusing on their established and potential clinical applications.

J Cancer Res Clin Oncol 2022; 148:1265-1268. [PMID: 35230510 DOI: 10.1007/s00432-021-03864-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Accepted: 11/15/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) is a crucial driven gene in non-small cell lung cancer (NSCLC), and the EGFR mutation rate in lung squamous cell carcinoma (SCC) is only 3 ~ 6.92%. Uncommon EGFR mutations, such as S768I, L861Q and G719X, accounting for approximately 15% of NSCLC harboring EGFR mutation. Afatinib, a second-generation EGFR-tyrosine kinase inhibitor (TKI), has been approved for NSCLC harboring uncommon mutations by the FDA in 2018. In our report, the lung SCC patient harboring uncommon compound EGFR mutation (G719A and R776C) benefited from afatinib. CASE PRESENTATION A case of a lung SCC patient harboring uncommon compound EGFR mutation (G719A and R776C) benefited from afatinib, and new MYC amplification was detected by next-generation sequencing (NGS) after disease progression. CONCLUSIONS This case first identified a patient with lung squamous cell carcinoma harboring uncommon compound EGFR mutation (G719A and R776C) benefited from afatinib and achieved 11 months of progression-free survival (PFS). Then, new MYC amplification was detected after disease progression, indicating that MYC amplification may be one of the reasons for afatinib resistance.

Abstract
Leptomeningeal carcinomatosis is a devastating consequence of late-stage cancer, and despite multimodal treatment, remains rapidly fatal. Definitive diagnosis requires identification of malignant cells in the cerebrospinal fluid (CSF), or frank disease on MRI. Therapy is generally palliative and consists primarily of radiotherapy and/or chemotherapy, which is administered intrathecally or systemically. Immunotherapies and novel experimental therapies have emerged as promising options for decreasing patient morbidity and mortality. In this review, the authors discuss a refined view of the molecular pathophysiology of leptomeningeal carcinomatosis, current approaches to disease management, and emerging therapies.

Abstract
Cerebrospinal fluid (CSF) is a clear and paucicellular fluid that circulates within the ventricular system and the subarachnoid space of the central nervous system (CNS), and diverse CNS disorders can impact its composition, volume, and flow. As conventional CSF testing suffers from suboptimal sensitivity, this review aimed to evaluate the role of next-generation sequencing (NGS) in the work-up of infectious, neoplastic, neuroimmunological, and neurodegenerative CNS diseases. Metagenomic NGS showed improved sensitivity—compared to traditional methods—to detect bacterial, viral, parasitic, and fungal infections, while the overall performance was maximized in some studies when all diagnostic modalities were used. In patients with primary CNS cancer, NGS findings in the CSF were largely concordant with the molecular signatures derived from tissue-based molecular analysis; of interest, additional mutations were identified in the CSF in some glioma studies, reflecting intratumoral heterogeneity. In patients with metastasis to the CNS, NGS facilitated diagnosis, prognosis, therapeutic management, and monitoring, exhibiting higher sensitivity than neuroimaging, cytology, and plasma-based molecular analysis. Although evidence is still rudimentary, NGS could enhance the diagnosis and pathogenetic understanding of multiple sclerosis in addition to Alzheimer and Parkinson disease. To conclude, NGS has shown potential to aid the research, facilitate the diagnostic approach, and improve the management outcomes of all the aforementioned CNS diseases. However, to establish its role in clinical practice, the clinical validity and utility of each NGS protocol should be determined. Lastly, as most evidence has been derived from small and retrospective studies, results from randomized control trials could be of significant value.

Abstract
RATIONALE Liquid biopsy of cerebrospinal fluid (CSF) and sequencing of cell-free DNA has rarely been used to identify epidermal growth factor receptor (EGFR) mutations, which can guide the design of precise, personalized treatment for patients with leptomeningeal metastasis from lung adenocarcinoma. PATIENT CONCERNS A 42-year-old woman with lung adenocarcinoma and leptomeningeal metastasis was admitted to our hospital on March 31, 2019. She exhibited no response to treatment with gefitinib, osimertinib, or chemoradiotherapy and was in critical condition, with an expected survival of <4 weeks. DIAGNOSIS Next-generation sequencing of CSF and peripheral blood samples identified an EGFR complex mutation (exon19del+K754E). INTERVENTIONS On April 10, 2019, the patient started oral afatinib (40 mg po qd), but she developed a grade III oral mucosal reaction 1 week later. The afatinib dose was reduced to 30 mg po qd. OUTCOMES At the follow-up examination on May 15, 2019, the patient reported relief from headaches. Enhanced magnetic resonance imaging revealed a reduction in abnormal leptomeningeal enhancement, and the CSF pressure and carcinoembryonic antigen levels were also reduced. The patient continued to respond to afatinib treatment (30 mg once daily) with minimal adverse effects. LESSONS This is the first case report of clinical improvement after afatinib treatment in a patient with lung adenocarcinoma and leptomeningeal metastasis harboring an EGFR complex mutation (exon19del+K754E), and thus provides a clinical reference for treatment with afatinib of cancers harboring EGFR compound mutations.

Abstract
One in every four deaths is due to cancer in Europe. In view of its increasing incidence, cancer became the leading cause of death and disease burden in Denmark, France, the Netherlands, and the UK. Without essential improvements in cancer prevention, an additional 775,000 cases of annual incidence have been prognosed until 2040. Between 1995 and 2018, the direct costs of cancer doubled from EUR 52 billion to EUR 103 billion in Europe, and per capita health spending on cancer increased by 86% from EUR 105 to EUR 195 in general, whereby Austria, Germany, Switzerland, Benelux, and France spend the most on cancer care compared to other European countries. In view of the consequent severe socio-economic burden on society, the paradigm change from a reactive to a predictive, preventive, and personalized medical approach in the overall cancer management is essential. Concepts of predictive, preventive, and personalized medicine (3PM) demonstrate a great potential to revise the above presented trends and to implement cost-effective healthcare that benefits the patient and society as a whole. At any stage, application of early and predictive diagnostics, targeted prevention, and personalization of medical services are basic pillars making 3PM particularly attractive for the patients as well as ethical and cost-effective healthcare. Optimal 3PM approach requires novel instruments such as well-designed liquid biopsy application. This review article highlights current achievements and details liquid biopsy approaches specifically in cancer management. 3PM-relevant expert recommendations are provided.

Abstract
BACKGROUND Brain is one of the most common target organ of lung cancer metastasis, while descriptions of intraventricular carcinomatosis could hardly be found among previous cases. To date no cases from lung adenocarcinoma have been reported in the literature. CASE PRESENTATION We report here a case of multiple intraventricular metastases from lung adenocarcinoma with EGFR G719X mutation. This 64-year-old woman was referred to our hospital with complaints of dizziness and vomiting. Target therapy with afatinib was initiated and the lesions in both lung and brain achieved good partial responses. CONCLUSIONS This case report revealed a phenomenon of rare intraventricular metastasis from lung cancer, which should be carefully distinguished from primary ventricular tumors. Compared to brain parenchyma metastasis, intraventricular lesions would cause more severe symptoms which may be rapidly progressive. Target therapy could become a potential option in such patients with non-drugresistant EGFR mutations.

Abstract
BACKGROUND In the majority of non-small cell lung cancer (NSCLC) patients with uncommon EGFR mutations, first generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are ineffective. The second-generation TKI, afatinib, is considered effective in patients with uncommon mutations, however, long-term survivors have been rare. CASE REPORT We report herein a patient with lung adenocarcinoma harboring double uncommon EGFR L861Q and G719X mutations, who is free of disease 32 months after initiation of afatinib therapy. To our best knowledge, this patient has the longest response among other patients with double uncommon mutations. CONCLUSION Patients with this type of NSCLC may obtain long-term survival with afatinib.
