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.

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.

OBJECTIVETo evaluate the surgical therapeutic strategy for non-small cell lung cancer (NSCLC) with (N2) mediastinal lymph node metastasis.

METHODSThe clinical data of 325 patients with N2 NSCLC treated surgically between 1961 and 1995 were analysed.

RESULTSThe over-all 5-year survival rate was 19.6%. Survival was higher in patients with radical resection than with palliative resection, with squamous-cell carcinoma than with adenocarcinoma, with sleeve lobectomy and pneumonectomy than with regular lobectomy, with 1 to 3 mediastinal metastatic lymph nodes than those over 4, and with adjuvant therapy (chiefly postoperative radiotherapy) than without. All these differences were statistically significant (P < 0.05). There was no 5-year survivor in patients with T3 or T4 tumor, nor in those with distant metastasis.

CONCLUSIONIt is suggested that surgery is the best choice for N2 NSCLC patients with T1 or T2 tumor, with non-adenocarcinoma, and with metastatic mediastinal lymph nodes less than 4 in number. Surgery is probably not a good choice in those with T3 tumor varieties. At operation, radical resection of the tumor and systematic removal of all hilar and mediastinal lymph nodes are essential for disease staging and survival improvement. Adjuvant therapy may improve long-term survival and is especially indicated in patients with residual tumor and/or metastatic mediastinal lymph nodes over 3 in number.

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.

OBJECTIVETo investigate the efficacy, time to progression, survival time and toxicity of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor Gefitinib (Iressa), a target therapy agent, in the treatment of advanced non-small cell lung cancer (NSCLC), and to analyze the factors affecting the efficacy and patients' survival.

METHODSFrom Nov. 2003 to May 2005, 91 patients with advanced NSCLC who failed from previous first-line chemotherapy were treated by gefitinib in this trial with a median chemotherapy cycle of six. Sixty-eight of these 91 patients (74.7%) had received a second-line chemotherapy. Seventy-six (83.5%) of the 91 patients had stage IV disease, and 42 (46.2%) had developed metastases at least two sites. Gefitinib was administered orally at a dose of 250 mg daily until disease progressed or severe toxicity developed. Clinical data were analyzed using chi-square test, Log-lank test, Cox regression and Kaplan-Meier survival analysis in SPSS 11.5.

RESULTS(1) Overall response rate was 20.9% (19/91) and the disease control rate (response and stable disease) was 63.7% (58/91). Patients'symptoms were improved in 72.7% (40/55), and ECOG score was improved or remained stable in 71.4% (65/91). The disease control rate of those who had adenocarcinoma, or received second-line chemotherapy or developed skin toxicity was significantly better than the other patients (P value = 0.04, 0.02, 0.00, respectively). (2) Median time to progress (TIP) was 5.0 months (95% CI 3.26-6.74). (3) Median following-up duration was 7.5 months (1-18. 5 months), and 1-year survival rate was 56.4%. Of the 56 patients (61.5%) who were still alive when following-up ended, 29 (51.8%) had stable disease, 20 had survived more than one year (12-18. 5 months). Non-smoker, stable diseases, skin toxicities, and controlled metastatic diseases during the treatment of gefitinib were the favorable factors affecting the survival (P value = 0.00, 0.00, 0.00, 0.01, respectively). (4) The main toxicity of gefitinib was grade I or II skin toxicity.

CONCLUSIONGefitinib, a target therapy agent which may be an alternative, is effective and tolerable in the treatment for advanced NSCLC patients who have failed in the first-line or even second-line chemotherapy. It can remarkablely improve the disease control rate and disease-related symptoms, and also prolong survival in the responders.

OBJECTIVETo investigate the time of whole brain irradiation and the prognostic factors for non-small lung cancer patients with brain metastasis.

METHODSFrom August 1996 to December 2003, 147 patients with brain metastasis from non-small cell lung cancer received whole brain irradiation. The patients were divided into two groups: with or without symptoms caused by brain metastasis, each group was then divided into two sub-groups, early whole brain irradiation group (the interval between the diagnosis of brain metastasis and the brain irradiation < or = one month) and late group ( the interval > one month ). Univariate and multivariate analysis (Cox regression) as well as Kaplan-Meier method in SPSS software package 11.5 was used to analyze the data of the 147 patients including 72 with brain metastasis symptom and 75 without.

RESULTSThe median survival time (MS) of patients with or without extracranial metastasis was 9.9 months and 11.3 months (P = 0.0002). Multivariate analysis indicated that extracranial metastasis was an independent prognostic factor (P = 0.0004). For 72 patients with brain metastasis symptom, the MS of the patients with and without extracranial metastasis was 9.3 months and 11.3 months (P = 0.0036). The MS of patients with early and late whole brain irradiation was 11.4 months and 9.2 months (P = 0.001). Multivariate analysis showed that extracranial metastasis, the interval between the diagnosis of brain metastasis and the whole brain irradiation were independent prognostic factors. However, for 75 patients without brain metastasis symptom, the MS difference of those with early or late whole brain irradiation was not statistically significant (P = 0.1643).

CONCLUSIONThe extracranial metastasis in non-small cell lung cancer patients with brain metastasis is an independent prognostic factors. Early whole brain irradiation may improve the survival for those with brain metastasis symptoms.

OBJECTIVEThe aim of this study is to evaluate the efficacy and safety of Gefitinib in the treatment of Chinese patients with recurrent advanced non-small-cell lung cancer (NSCLC).

METHODS120 patients were enrolled in this trial from September 2002 to March 2005, and 103 patients were evaluable. All patients were histologically or/and cytologically confirmed to have a locally advanced or metastatic NSCLC, and failed to previous standard treatments. The patients received orally 250 mg of Gefitinib once daily until the disease progression or intolerance to toxicity. First evaluation of response was undertaken one month after drug initiation, then every 2 or 3 months till disease progression. Each patient was followed up every 6 months untill death or end of follow-up.

RESULTSAmong the 103 evaluable patients, the objective response rate was 18.4% (19/103), and the disease control rate was 51.5% (53/103). The median time to progression (mTTP) was 3 months (range: 0.2 approximately 40), the median survival time (MST) was 9.8 months (range: 0.5 approximately 51), the 1-, 2-, 3-year survival rates were 44.7%, 26.4% and 13.2%, respectively. The TTP of 41 patients was longer than 6 months with a MST of 25.5 months. The results of COX model analysis suggested that the patients with adenocarcinoma, rash and favourable performance status (PS) had longer TTP. The patients with favourable PS and well controlled disease had longer survival time. Adverse events included skin rash, dry skin, diarrhea and elevation of serum glutamate pyruvate transaminase (SGPT), and were usually mild.

CONCLUSIONGefitinib is effective in treatment of patient with recurrent advanced NSCLC. The patients with controlled disease may achieve a long survival, and the adverse reactions are mild and tolerable.

OBJECTIVETo explore high effective and low toxic chemotherapeutic regimens in the treatment of non-small-cell lung cancer (NSCLC).

METHODSA total of 126 patients with advanced NSCLC (Stage III, IV) were randomly divided into two groups: high dose impulsion chemotherapy group (HDIC group) and low dose density chemotherapy group (LDDC group) with 54 patients in HDIC group who received paclitaxel 135-175 mg/m2 on day 1, DDP 80-100 mg/m2 on day 1 and BCNU 125 mg given for brain metastasis on days 1-3 in a 4-6 weeks cycle. Seventy-two patients in LDDC group were given paclitaxel 60-80 mg/m2 on day 1, DDP 40-80 mg/m2 on day 1 repeated weekly and BCNU 125 mg given for brain metastasis with an interval of 2 weeks, in a 4-6 weeks cycle. Antiemetic agent and fluid were administered routinely in HDIC group whereas LDDC group was given antiemetic agent only.

RESULTSOf 157 courses in HDIC group, an average of 2.9 courses per patient, CR 3, PR 23, SD 17 and PD 11 were observed. The effective remission rate was 48.1%, the median effective remission period was 4.5 months and the 1-year survival rate was 46.3%. Of 184 courses in LDDC group, an average of 2.6 courses per patient, CR 9, PR 30, SD 24 and PD 9 were observed. The effective remission rate was 54.2%, the median effective remission period was 6 months and the 1-year survival rate was 56.9%. The effective remission rate and the 1-year survival rate were higher in HDIC group than those in LDDC group, but there was no statistical difference between the two groups (P > 0.05). Severe toxicity was higher in HDIC group than in LDDC group. Two patients in HDIC group died of treatment-related complications (3.7%). Quality of life was better in LDDC group (70.8%) than in HDIC group (51.9%).

CONCLUSIONWhen comparing with high dose impulsion, low dose density regimen of paclitaxel plus cisplatin is more effective and better tolerated with improvement of quality of patients' life in the treatment of NSCLC due to its low dose and short interval duration.
