Objective Image evaluation strategy for lung cancer patients has difficulty obtaining the appropriate quantity of diffuse lung nodules and bone metastases. The study was to demonstrate whether early variations in the levels of serum 4-tumor markers (4-TMs)(carcinoembryonic antigen [CEA], cancer antigen [CA]125, CA19-9, and CA15-3) after TKI targeted therapy were associated with treatment response in patients with lung adenocarcinoma. Methods Patients with stage IIIB-IV lung adenocarcinoma taking epidermal growth factor receptor (EGFR) TKIs or anaplastic lymphoma kinase (ALK) inhibitors were enrolled prospectively from June 2012 to February 2015. According to the variations of the percentage of change in 4-TM levels (4-TMpc), we divided patients into ascending (increases in 4-TMpc over the 7th- 14th day) and descending (decreases in 4-TMpc over the 7th- 14th day) groups. Results 184 patients were enrolled, and 89% had at least one of the pre-treatment evaluable TMs and were further analyzed. An excellent response to the TKI targeted therapy was accurately predicted in the descending group, as determined using receiver operating characteristic curve analysis (an area under the curve, 0.83). Multivariate Cox hazards model analyses demonstrated that the type of 4-TMpc and mutation status were the strongest predictors of progression-free survival (PFS)(descending versus ascending, hazard ratios [HR] 0.30, 95% confidence interval [CI], 0.19–0.47; sensitive mutation versus wide type, HR 0.30, 95% CI, 0.19–0.48). Conclusions Type of 4-TMpc 14 days after TKI targeted therapy is associated with an image response and PFS, without regarding mutation status, in patients with advanced lung adenocarcinoma.

Purpose Sorafenib and lenvatinib are oral multikinase inhibitors targeting vascular endothelial growth factor receptor (VEGFR) and approved for radioiodine (RAI)-refractory differentiated thyroid cancer (DTC). However, there are no approved second- or third-line therapies. MET is implicated in resistance to VEGFR inhibitors. Cabozantinib is an oral multikinase inhibitor targeting MET in addition to VEGFR and is approved for medullary thyroid cancer. In a phase I study of cabozantinib, five of eight patients with DTC previously treated with a VEGFR-targeted therapy had an objective response to cabozantinib. Patients and Methods Patients with RAI-refractory disease with Response Evaluation Criteria in Solid Tumor (RECIST) measurable disease and evidence of progression on prior VEGFR-targeted therapy were enrolled in this single-arm phase II study. The cabozantinib starting dose was 60 mg/day orally but could be escalated to 80 mg if the patient did not experience a response. Patients underwent tumor assessment according to RECIST v1.1 every 8 weeks. In this study, if at least five of 25 response-evaluable patients had an objective response, cabozantinib would be considered a promising agent in this patient population. Results Twenty-five patients were enrolled. The median age was 64 years, and 64% of patients were men. Twenty-one patients had received only one prior VEGFR-targeted therapy (sorafenib, pazopanib, or cediranib), and four patients had received two such therapies. The most common treatment-related adverse events were fatigue, weight loss, diarrhea, palmar-plantar erythrodysesthesia, and hypertension. One drug-related death was noted. Of the 25 patients, 10 (40%) had a partial response, 13 (52%) had stable disease, and two (8%) had nonevaluable disease. The median progression-free survival and overall survival were 12.7 months and 34.7 months, respectively. Conclusion Cabozantinib demonstrated clinically significant, durable objective response activity in patients with RAI-refractory DTC who experienced disease progression while taking prior VEGFR-targeted therapy.

Objective:This paper aims to study the mutation of epidermal growth factor receptor (EGFR) gene in fresh cytological specimens from patients with lung adenocarcinoma, and to determine the prognosis of positive patients by tyrosine kinase inhibitor (TKI). Methods: A total of 313 specimens from needle aspiration and pleural effusion were collected in the Cancer Detection Center of the Fourth Hospital of Hebei Medical University. After HE and immunocytochemistry stainings, the specimens were diagnosed as lung adenocarcinoma by two cytology pathologists. Themutation of 18-21 exon was detectied using ARMS to observe mutations situation. Then, the objective response rate (ORR) and the progression-free survival (PFS) between the targeted group and the chemotherapy group of patients were comparedith. Results: Among 313 cases, 293 cases of lung adenocarcinoma were diagnosed, and DNA specimens were extracted from 288 cases. The success rate was about 98.3%. 130 mutations were found and the rate was 45.1%. EGFR mutation of adenocarcinoma patients mainly occurred to females, nonsmokers, but had nothing to do with age. The ORR was statistically different between the targeted group with chemotherapy (P<0.01), and PFS curve of targeted group was on chemotherapy group. The efficacy and the survival time of targeted group and targeted and chemotherapy group were superior to that of chemotherapy group. The results of the EGFR mutation and the prognosis of the tested positive patients in the fresh cytology samples were consistent with that from previous literatures. Conclusion: The results of the testwere accurate, and fresh cytological specimens can be used as a replacement for tumor tissue specimens.

CYFRA 21-1 is a prognostic marker for non–small cell lung cancer. The serum CYFRA 21-1 level is also known as an adjunct for the diagnosis of lung squamous cell carcinoma. This study aimed to examine whether CYFRA 21-1 has predictive implications for nivolumab therapy in patients with advanced lung adenocarcinoma. Of the 79 patients who were treated with nivolumab therapy at the Shizuoka Cancer Center between December 2015 and September 2016, we retrospectively reviewed the data of 50 patients. The patient characteristics were as follows: age <70/≥70 years: 43 (86%)/7; male/female: 31 (62.0%)/19; Eastern Cooperative Oncology Group performance status 0–1/2: 43 (86%)/7; smoking status: no/yes: 18 (36%)/32; epidermal growth factor receptor mutation status negative/positive: 36 (72%)/14; CYFRA 21-1 ≥2.2/<2.2 ng/mL: 28 (56%)/22; carcinoembryonic antigen ≥5/<5 ng/mL: 29 (58%)/21; and number of prior regimens 2–3/≥4: 16 (32%)/34. With a median follow-up of 263.5 (range, 64–352) days, the median progression-free survival was 70 days. The clinical variables investigated using univariate analysis were as follows: age (p = 0.423), carcinoembryonic antigen (p = 0.888), epidermal growth factor receptor mutation status (p = 0.105), performance status (p = 0.968), sex (p = 0.210), number of prior regimens (p = 0.146), CYFRA 21-1 (p = 0.026), and smoking status (p = 0.041). A multivariate analysis identified a serum CYFRA 21-1 level ≥2.2 ng/mL as an independent predictor of a favorable outcome (hazard ratio, 0.44; 95% confidence interval, 0.23–0.85; p = 0.015; median progression-free survival, 155 vs 51.5 days). In conclusion, CYFRA 21-1 might be an independent predictor of outcome for patients with advanced lung adenocarcinoma treated with nivolumab.

This report concerns a patient with skeletal muscle metastases due to lung adenocarcinoma harbouring an echinoderm microtubule-associated protein-like-4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement, who was successfully treated with lorlatinib after resistance to alectinib. A right lower lobectomy based on a diagnosis of lung adenocarcinoma was performed on a 77-year-old Japanese woman. After 7 months of surgical resection, a mass in the right calf was observed. A fine-needle aspiration biopsy from the mass was performed and the mass was diagnosed as metastatic adenocarcinoma harbouring EML4-ALK rearrangement. Alectinib was administered for 10 months. Then, administration of lorlatinib, an ALK tyrosine kinase inhibitor classified as third generation, was initiated after resistance to treatment with alectinib. After starting treatment with lorlatinib, the gastrocnemius tumour diminished and has maintained a stable condition. Our case suggests that EML4-ALK positive lung adenocarcinoma is treatable with lorlatinib after resistance to treatment with alectinib.

Epidermal growth factor receptor ( EGFR) mutations and anaplastic lymphoma kinase ( ALK) rearrangements are considered mutually exclusive in non-small cell lung cancer (NSCLC), especially in lung adenocarcinoma (LUAC). However, sporadic cases harboring concomitant EGFR and ALK alterations have been increasingly reported. There is no consensus opinion regarding the treatment of patients positive for both molecular alterations. NSCLC with EGFR/ ALK coalterations should be separated into two subtypes: unifocal and multifocal LUAC. Here, we present an overview of the available literature regarding this rare group of patients to provide useful suggestions for therapeutic strategies.

Objective This study aimed to identify a predictive marker of response to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with EGFR-mutant advanced lung adenocarcinoma. Methods A cohort of 190 patients with EGFR-mutant advanced lung adenocarcinoma was analyzed. Receiver operating characteristic curve analysis was used to evaluate the optimal cutoffs for fibrinogen levels, the neutrophil-to-lymphocyte ratio (NLR), and the platelet-to-lymphocyte ratio (PLR) for predicting progression-free survival (PFS). Univariate and multivariate survival analyses were performed to identify factors correlated with PFS and overall survival (OS). Results High NLR was associated with worse performance status. In univariate analysis, fibrinogen levels, NLR, and PLR were correlated with OS and PFS. In multivariate analysis, all three variables remained predictive of OS, whereas only fibrinogen levels and PLR were independent prognostic factors for PFS. Furthermore, the combination of fibrinogen levels and PLR (F-PLR score) could stratify patients into three groups with significantly different prognoses, and the score was independently predictive of survival. Conclusion The F-PLR score predicted the prognosis of patients with EGFR-mutant advanced lung adenocarcinoma who received EGFR-TKIs, and this score may serve as a convenient blood-based marker for identifying high-risk patients.
