Abstract
INTRODUCTION Lung cancer still remains undiagnosed for most patients until the disease is inoperable. AREAS COVERED We performed search on PubMed with the keywords: EBUS, radial-EBUS, bronchoscopy, lung cancer, electromagnetic navigation, ct-biopsy, transthoracic biopsy. We present diagnostic equipment and imaging techniques such as positron emission tomography, endoscopical navigation systems, endobronchial ultrasound, radial-endobronchial ultrasound, transthoracic ultrasound biopsy, and computed tomography guided biopsies. EXPERT OPINION However, lack of early disease symptoms remains the most important issue and therefore we should direct our efforts to screening and early disease diagnosis. An algorithm is proposed for biopsy upon initial disease diagnosis.

Abstract
BACKGROUND Several genetic driver alterations have been identified in micropapillary lung adenocarcinoma (MPA). However, the frequency of co-alteration of ROS1, EGFR, and EML4-ALK is yet unclear. Herein, we investigated the relationship between clinicopathologic characteristics and well-identified driver mutations of MPA compared with non-micropapillary lung adenocarcinoma (LA). METHODS Formalin-fixed paraffin-embedded (FFPE) sections derived from lung adenocarcinoma patients who never received adjuvant chemotherapy or radiation therapy prior to surgical resection were collected from October 2016 to June 2019. EGFR mutations, ROS1 rearrangements, and EML4-ALK fusion were identified in a set of 131 MPA and LA cases by using the amplification refractory mutation system (ARMS). The response rate and duration of response were assessed using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). RESULTS EGFR mutations had occurred in 42 (76.4%) MPA patients and 42 (55.3%) LA patients. Interestingly, ROS1 rearrangements were highly enriched only in the MPA cases (6/55, 10.9%) but rarely in the LA cases (1/76, 1.3%). Furthermore, 7.3% (4/55) MPA samples had double gene mutations, while only 1.3% (1/76) LA cases had double gene alterations. Of 5 patients with harboring two driver oncogene mutations, four patients (80%) obtained partial response, and one patient (20%) suffered recurrence. CONCLUSIONS A higher prevalence of ROS1 rearrangement or combined mutations of ROS1, EGFR, and EML4-ALK may play a critical role in the tumorigenesis of MPA. These findings provide a novel therapeutic strategy for patients with malignant MPA through combining TKIs than one TKI.

ALK and ROS1 rearrangement tested by ARMS-PCR in non-small-cell lung cancer patients via cytology specimens: The experience of Shanghai Pulmonary Hospital. Diagn Cytopathol 2020; 48:524-530. [PMID: 32150350 DOI: 10.1002/dc.24404] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 01/31/2020] [Accepted: 02/20/2020] [Indexed: 12/28/2022]
Abstract
BACKGROUND Cytology specimens are the main samples used for the diagnosis of advanced lung cancer. The objective of our study was to assess anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 receptor tyrosine kinase (ROS1) genes by an amplification refractory mutation system (ARMS)-polymerase chain reaction (PCR) using cytology specimens and to then evaluate the mutation frequency of ALK and ROS1 in non-small-cell lung cancer (NSCLC) patients. METHODS A large cohort that consisted of 8180 NSCLC patients who were genetically tested using cytology samples or formalin-fixed and paraffin-embedded (FFPE) samples (tumor tissue or biopsy) from January 2015 to December 2018 were screened. The gene rearrangement ratio and clinical characteristics of the two sample groups were analyzed by SPSS software. RESULTS In our hospital, cytology specimens are the main resource used for gene testing in NSCLC. In most cases, an abundant quantity of nucleic acid was extracted from the residual liquid-based cell pellet for testing the ALK and ROS1 genes. In certain cases, when the residual cell pellet was insufficient for the gene testing, the cell block and liquid-based cell smear served as alternative options. In addition, we retrospectively analyzed our previous data, and the mutation ratio of the ALK/ROS1 rearrangements obtained by using the cytology samples (4.98%/1.80%) and the FFPE samples (6.06%/1.62%) was almost the same (P-value = .09/.634). CONCLUSIONS This study demonstrated that AMRS-PCR method can effectively identify ALK and ROS1 gene rearrangements and cytology specimens might be an excellent source for routine molecular testing in patients with advanced NSCLC.
