Objective: To investigate the clinical features of patients with non-small cell lung cancer(NSCLC) harboring uncommon epidermal growth factor receptor(EGFR) mutations, and the treatment outcomes of EGFR tyrosine kinase inhibitors(TKIs) in these patients.Methods: We retrospectively analyzed the data of 128 NSCLC patients pathologically diagnosed with uncommon EGFR mutation in the Department of Pathology, National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College and Beijing Hospital from January 2010 to December 2015, including 40 advanced patients who received EGFR-TKI.Results: Among the total 128 patients, 11 patients were non-adenocarcinoma, including squamous carcinoma(3.9%), adenosquamous carcinoma(2.3%), large cell carcinoma(0.8%), and composite neuroendocrine carcinoma(1.6%). Single mutations accounted for 75.0%(96/128), including G719X(29.7%), S768I(18.0%), 20 exon insertion(13.3%), L861Q(12.5%), De novo T790M(0.8%), and T725(0.8%). Thirty-two patients harbored complex mutations. Forty advanced patients received EGFR-TKI, the objective response rate(ORR) was 20.0%,the disease control rate(DCR) was 85.0%, and the progression-free survival(PFS) was 6.4 [95% confidence interval(95% CI), 4.8–7.9] months. The exploratory analysis of tumor response and PFS in 33 patients with G719X/S768I/L861 Q subtypes showed that ORR was 21.2%(7/33), the DCR was 93.9%(31/33), and PFS was 7.6(95% CI, 5.8–9.4) months. Patients with exon 20 insertion mutation and De novo T790 M experienced rapid disease progression with PFS no more than 2.7 months.Conclusions: Uncommon EGFR-mutant NSCLCs are heterogeneous, EGFR-TKIs can have different efficacy in this specific subtype, and thus further individual assessment is required for each case. 展开更多

Objective: Data on the clinical activity of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in patients with non-small-cell lung cancer (NSCLC) and uncommon EGFR mutations remain insufficient. This study aimed to investigate the effect of first-line EGFR-TKIs or platinum-based chemotherapy in NSCLC patients with uncommon EGFR mutations. Methods: We retrospectively enrolled 504 patients with EGFR-mutant NSCLC. The clinical characteristics and treatment outcomes were collected and compared between patients with common and uncommon EGFR-mutant NSCLC. Results: Seventy patients (13.9%) harboring uncommon EGFR mutations were included. Thirty of these patients received EGFR-TKIs and 40 received platinum-based chemotherapy as first-line therapy. The objective response rate (ORR) and median progression-free survival (mPFS) of patients treated with TKIs in the uncommon mutation group was significantly inferior to that in the common mutation group (ORR: 23.3% vs. 51.8%, P=0.003; mPFS: 7.1 vs. 10.9 months, P〈0.001). In the uncommon group, mPFS was similar between first-line EGFR-TKIs treatment and platinum-based chemotherapy (7.1 vs. 6.1 months, P=0.893). In patients with EGFR G719X or L861Q mutations, the mPFS was longer in the first-line EGFR-TKIs treatment group than in the chemotherapy group, but the difference was not statistically significant (G719X: 8.2 vs. 5.8 months, P=0.061; L861Q: 7.6 vs. 4.1 months, P=0.872). Multivariate analyses identified adenocarcinoma (P=0.003) as the independent predictive factor for PFS in patients with uncommon EGFR mutations who were treated with first-line EGFR-TKIs. Conclusions: The current study demonstrated that the effect of first-line EGFR-TKIs was similar to that of platinum-based chemotherapy in patients with uncommon EGFR-mutant NSCLC. Adenocarcinoma was the independent predictive factor for PFS in uncommon EGFR-mutant NSCLC patients treated with first-line EGFR- TKIs. 展开更多

There is an increasing role for endoscopic ultrasound(EUS)-guided interventions in the treatment of many conditions. Although it has been shown that these types of interventions are effective and safe, they continue to be considered only as alternative treatments in some situations. This is in part due to the occurrence of complications with these techniques, which can occur even when performed by experienced endosonographers. Although common complications have been described for many procedures, it is also crucial to be aware of uncommon complications. This review describes rare complications that have been reported with several EUS-guided interventions. EUS-guided biliary drainage is accepted as an alternative treatment for malignant biliary obstruction. Most of the uncommon complications related to this procedure involve stent malfunction, such as the migration or malposition of stents. Rare complications of EUS-guided pancreatic pseudocyst drainage can result from air embolism and infection. Finally, a range of uncommon complications has been reported for EUS-guided celiac plexus neurolysis, involving neural and vascular injuries that can be fatal. The goal of this review is to identify possible complications and promote an understanding of how they occur in order to increase general awareness of these adverse events with the hope that they can be avoided in the future. 展开更多

The 2004 discovery of EGFR mutations,followed by ALK rearrangements,ushered in a targeted therapy era for advanced non-small cell lung cancer(NSCLC).Tyrosine kinase inhibitors targeting gene alterations have substantially improved survival and quality of life for patients with NSCLC.In the last decade,rearrangements of the ROS1 oncogene have been incorporated into healthcare practice that are applicable to another small subgroup of patients who benefit from similar targeted strategies.Recent genome studies of lung adenocarcinoma have identified other possible therapeutic targets,including RET,NTRK fusions,c-MET alterations,and activating mutations in KRAS,BRAF,and HER2,all with frequencies greater than 1%.Lung cancers harbouring these genome changes can potentially be treated with agents approved for other indications or under clinical development.This review updates the therapeutic arsenal that especially targets those genes. 展开更多

Rectal neuroendocrine tumors consist approximately the 5%-14% of all neuroendocrine neoplasms in Europe. These tumors are diagnosed in relatively young patients,with a mean age at diagnosis of 56 years. Distant metastases from rectal neuroendocrine tumors are not very common. Herein we describe a case of a rectal neuroendocrine tumor which metastasized to the lung,mediastinum and orbit. This case underscores the importance of early identification and optimal management to improve patient's prognosis. Therefore,the clinical significance of this case is the necessity of physicians' awareness and education regarding neuroendocrine tumors' diagnosis and management. 展开更多

Objective G719 X is the most frequently seen uncommon mutation of the epidermal growth factor receptor(EGFR) gene, which is a point mutation at exon 18 with three common subtypes, G719 A/G719 C/G719 S. This study explored the clinicopathological characteristics of the G719 X mutation and investigated the efficacy of EGFR-tyrosine kinase inhibitor(TKI) treatment and chemotherapy in patients with the G719 X mutation; the survival rate after these different treatment modalities were then analyzed in order to provide evidence for clinical treatment.Methods Clinical data of 41 patients with the G719 X mutation admitted in the Beijing Chest Hospital, Capital Medical University from September 2014 to July 2018, were collected and the EGFR mutations were detected by amplification refractory mutation system-polymerase chain reaction(ARMS-PCR). The clinicopathological characteristics of the G719 X mutation were analyzed, and the relationship among the G719 X mutation, the efficacy of different treatment modalities, and the progression-free survival(PFS) was analyzed. Results Of the 41 cases, 24(58.5%) were G719 X single mutations and 17(41.5%) were compound mutations, including G719 X/S768 I, G719 X/L861 Q, G719 X/19 del, and G719 X/c-Met compound mutation. The objective response rate(ORR) of first-line EGFR-TKI therapy was 50%(6/12), the disease control rate(DCR) was 83.3%(10/12), and the median PFS(mPFS) was 9 months. After resistance to EGFR-TKI in the previous treatment, the ORR(71.4%, 5/7) and DCR(100%, 7/7) were still high following EGFR-TKIs, by an mPFS of 8 months. The ORR of chemotherapy was 33.3%(2/6), the DCR was 100%(6/6), and the mPFS was 6 months. Conclusion G719 X is an uncommon mutation of the EGFR gene and is sensitive to many EGFR-TKIs. It can be treated with the second-or third-generation EGFR-TKIs after resistance to the first-generation EGFR-TKIs. G719 X mutation also showed favorable effect to chemotherapy. 展开更多

Uncommon epidermal growth factor receptor(EGFR) mutations account for 10% 20% of all EGFR mutations in non-small-cell lung cancer(NSCLC). The uncommon EGFR-mutated NSCLC is associated with poor clinical outcomes and generally achieved unsatisfactory effects to the current therapies using standard EGFR-tyrosine kinase inhibitors(TKIs), including afatinib and osimertinib. Therefore, it is necessary to develop more novel EGFR-TKIs to treat uncommon EGFR-mutated NSCLC.Aumolertinib is a third-generation EGFR-TKI approved in China for treating advanced NSCLC with common EGFR mutations. However, it remains unclear whether aumolertinib is effective in uncommon EGFR-mutated NSCLC. In this work, the in vitro anticancer activity of aumolertinib was investigated in engineered Ba/F3 cells and patient-derived cells bearing diverse uncommon EGFR mutations. Aumolertinib was shown to be more potent in inhibiting the viability of various uncommon EGFR-mutated cell lines than those with wild-type EGFR. And in vivo, aumolertinib could also significantly inhibit tumor growth in two mouse allograft models(V769-D770insASV and L861Q mutations) and a patientderived xenografts model(H773-V774insNPH mutation). Importantly, aumolertinib exerts responses against tumors in advanced NSCLC patients with uncommon EGFR mutations. These results suggest that aumolertinib has the potential as a promising therapeutic candidate for the treatment of uncommon EGFR-mutated NSCLC. 展开更多
