The lungs are the most common sites of metastases from non-pulmonarymalignancies. Endobronchial metastases are rare and have no specificity in clinical manifestations,thus being prone to misdiagnosis and delayed treatment.The common tumors associated with endobronchial metastasis are renal,breast,and colorectal cancers.This article reported one case of postoperative rectal cancer with endobronchial and lung metastases,which was relieved by high-frequency electrocautery ablation via bronchoscope,chemotherapy,and targeted drugs,aiming to provide a reference for clinical diagnosis and treatment.

BACKGROUND: Advanced epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma had a high overall incidence of brain metastasis during the full course, and local brain radiotherapy combined with systemic targeted therapy may be a better strategy. This study aimed to identify the prognostic factors of EGFR-mutant brain-metastatic lung adenocarcinoma patients who received EGFR-tyrosine kinase inhibitors (EGFR-TKIs) in combination with gamma knife radiosurgery. METHODS: Retrospective analysis of EGFR-mutant lung adenocarcinoma patients with brain metastases which developed at initial diagnosis or during EGFR-TKIs treatment period were performed. Intracranial progression free survival (PFS) was statistically analyzed between different subgroups to find out the prognostic factors including gender, age, smoking history, extracranial metastasis, EGFR mutation type, size and number of intracranial lesions, carcino-embryonic antigen (CEA) level, lung-molGPA score and so on. RESULTS: A total of 74 EGFR-mutant brain-metastatic lung adenocarcinoma patients were enrolled in this study, with median intracranial PFS of 14.7 months. One-year intracranial-progression-free rate was 58.5%, and two-year rate was 22.2%. Univariate survival analysis showed that patients with lower CEA level at initial diagnosis (<10 ng/L)(16.9 months vs 12.6 months, P=0.012) and smaller intracranial lesions (<2 cm)(15.4 months vs 10.8 months, P=0.021) and higher lung-molGPA score (>3)(15 months vs 12.6 months, P=0.041) were prone to have a superior intracranial PFS. Multivariate analysis showed that CEA≥10 ng/mL and intracranial lesion≥2 cm were the independent risk factors of intracranial PFS. CONCLUSIONS EGFR-TKIs in combination with gamma knife radiosurgery was an efficient treatment option to control the cranial tumor lesion. CEA≥10 μg/L at initial diagnosis and intracranial lesion≥2 cm were the risk factors of EGFR-mutant brain-metastatic lung adenocarcinoma patients receiving EGFR-TKIs in combination with gamma knife radiosurgery.

Lung cancer is the most commonly diagnosed cancer worldwide. Malignant pleural effusion (MPE) caused by advanced lung cancer seriously affect the patients' quality of life and prognosis. The management of MPE includes thoracentesis, pleurodesis, indwelling pleural catheters and drug perfusion in pleural cavity. Vascular endothelial growth factor (VEGF) and its receptor are a group of important ligands and receptors that affect angiogenesis. They are the main factors controlling angiogenesis, and they play an important role in the formation of MPE. Bevacizumab is a recombinant humanized VEGF monoclonal antibody, competitively binding to endogenous VEGF receptor. Bevacizumab can inhibit new blood vessel formation, reduce vascular permeability, prevent pleural effusion accumulation and slow the growth of cancers. This review aims to discuss the progress of bevacizumab in the treatment of MPE caused by non-small cell lung cancer (NSCLC), and explore the clinical application, efficacy, safety and future direction of bevacizumab.

BACKGROUND: Bevacizumab combined with platinum-based chemotherapy has been recommended as the first-line agent in advanced nonsquamous non-small cell lung cancer (NSCLC) without driven gene, but this regimen is not common in the second-line or later-line treatment of non-squamous NSCLC. The aim of this study is to investigate the efficacy and safety of bevacizumab combined with chemotherapy as second-line or later-line treatment in advanced non-squamous NSCLC. METHODS: We retrospectively reviewed the clinical data of advanced nonsquamous NSCLC patients who were treated with bevacizumab after first-line treatment failure and they were hospitalized in the Affiliated Cancer Hospital of Zhengzhou University from January 2014 to June 2017, and Kaplan-Meier method, Log-rank test and Cox model were used for analysis. RESULTS: A total of 62 patients were included in the analysis. The total objective response rate (ORR) was 32.2%, and the disease control rate (DCR) was 96.8%. The median progression-free survival (PFS) was 6.4 months (95%CI: 6.05-6.83), and the median overall survival (OS) was 20.4 months (95%CI: 12.98-27.76). In the subgroup analysis, there was no significant difference in median PFS between patients with brain metastases and those without brain metastases (6.2 months vs 6.4 months, P=0.052). Cycles of bevacizumab (>6 or ≤6 cycles) was an independent influencing factor of PFS (P=0.004). The most common adverse events were leukopenia, fatigue, nausea, thrombocytopenia and hypertension. CONCLUSIONS In the second-line or later-line treatment, bevacizumab combined with chemotherapy is an effective and safe regimen for advanced non-squamous NSCLC.

OBJECTIVE: This is a retrospective study aimed at clarifying the details of recurrence patterns and sites in patients with cervical cancer treated with definitive radiation therapy (RT). METHODS: Data were analyzed from consecutive patients, admitted to the University of Tokyo Hospital (Tokyo, Japan) between 2001 and 2013, who had received definitive RT, with or without chemotherapy, for International Federation of Gynecology and Obstetrics stages IB-IVA cervical cancer. RESULTS: One hundred and thirty-seven patients formed the patient cohort. The median follow-up period for surviving patients was 57.0 months. A complete response was achieved in 121 patients (88%). Of these, 36 (30%) developed a cancer recurrence during follow-up. The first sites of recurrence were located in intra-RT fields in nine, outside RT fields in 20, and both in seven patients. In the intra-RT field group, all patients showed a local recurrence, while no one experienced an isolated pelvic lymph node (PLN) recurrence. In the outside RT field group, the most frequent site of recurrence was lung (60%), and three-quarters of patients were free from intra-RT field recurrence until the last follow-up. Of the entire cohort, including 48 PLN-positive patients, only seven patients (5.1%) developed PLN persistence or recurrence, all in the common iliac, internal iliac, and/or obturator nodes, and all with another synchronous relapse. CONCLUSION: Local disease was a major type of intra-RT field recurrence, while PLN control was favorable even in initially PLN-positive patients. The predominance of outside RT field recurrence alone highlights issues concerning distant control, including the intensity enhancement of systematic therapy.

OBJECTIVE: To study the expression of excision repair cross-complementing 1 (ERCC1) and the treatment of cisplatin-based chemotherapy in local advanced nasopharyngeal carcinoma (NPC). METHOD: The expression of ERCC1 protein in 107 cases with NPC and in 48 normal nasopharyngeal tissues adjacent to the cancer was detected by immunohistochemical method. RESULT: High expression of ERCC1 was observed in 52 cases with NPC, and 18 cases normal nasopharyngeal tissues, there was no statistically significant differences between them. The expression of ERCC1 protein was significant correlated with patient total TNM stage, but not significantly correlated with age, gender, histological type, T stage and N stage. The recent treatment efficiency in Low ER-CCl expression cases was higher than high expression cases. There was statistically significant difference between them. In 97 follow-up cases, 2 cases died, 5 cases with liver and lung metastasis, there was no statistically significant difference between them. CONCLUSION ERCC1 expression maybe regarded as indicator platinum based chemotherapy sensitivity prediction in nasopharyngeal carcinoma, and also helpful for formulating individualized treatment. The immunohistochemical detection is also simple and effective detection method for ERCC1 expression.

Gefitinib is regarded as a relatively safe agent for the treatment of an advanced non-small cell lung cancer (NSCLC). Pulmonary toxicity such as interstitial lung disease associated with gefitinib is uncommon with an estimated all time incidence around 1% worldwide. Moreover, a case of gefitinib associated with pulmonary cystic changes has not been reported yet. In this report we present a case of progressive multiple air cystic changes in both lungs in a patient with NSCLC and intrapulmonary metastases who underwent a gefitinib therapy.

Although hematogenous metastasis of cancer to the gastrointestinal track is rare, it sometime has been reported in patients with malignant melanoma and breast cancer. However, it is extremely rare for lung cancer to metastasize to the stomach, not to mention solitary gastric metastasis. Herein, the authors report a case of a 69-year-old man who was initially diagnosed with lung cancer with synchronous primary gastric cancer which proved to be lung cancer with solitary gastric metastasis after the operation.
