OBJECTIVETo evaluate the role of nimotuzumab in combination with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC).

METHODSThe clinical data of 37 NSCLC patients who received nimotuzumab in combination with chemotherapy in Tianjin Medical University Cancer Hospital from January 2009 to October 2010 were retrospectively reviewed. Of the thirty-seven patients, 12 patients were in stage III B, 25 patients in stage IV. Twenty-four patients recived platinum-based chemotherapy in combination with nimotuzumab, 13 patients recived nonplatinum-based chemotherapy in combination with nimotuzumab. Ten patients received nimotuzumab in combination with chemotherapy as first-line regimen, 23 patients as second-line regimen, 4 patients as third-line regimen.

RESULTSOf the 37 advanced NSCLC patients who received nimotuzumab in combination with chemotherapy, the total number of chemotherapy were 137 cycles, the mean number was 3.7 cycles. One patient had complete remission (CR), 9 patients had partial remission (PR), 16 cases had stable disease (SD), and 11 patients had progressive disease (PD). The response rate (RR) was 27% and clinical benefit rate (CBR) was 70.3%. The main side effects were bone marrow suppression and gastrointestinal reactions. Grade I acneiform rash was found in one patient.

CONCLUSIONThe regimen of nimotuzumab in combination with chemotherapy can improve the response rate and was well tolerated in patients with advanced non-small cell lung cancer.

Ethnicity might be associated with treatment outcomes in advanced prostate cancer. This study aimed to evaluate the efficacy and safety of androgen deprivation therapy (ADT) combined with apalutamide in East Asians with metastatic castration-sensitive prostate cancer (mCSPC). The original phase 3 Targeted Investigational Treatment Analysis of Novel Anti-androgen (TITAN) trial was conducted at 260 sites in 23 countries. This subgroup analysis included patients enrolled in 62 participating centers in China, Japan, and Korea. Radiographic progression-free survival (PFS), time to prostate-specific antigen (PSA) progression, and PSA changes from baseline were compared between groups in the East Asian population. The intent-to-treat East Asian population included 111 and 110 participants in the apalutamide and placebo groups, respectively. The 24-month radiographic PFS rates were 76.1% and 52.3% in the apalutamide and placebo groups, respectively (apalutamide vs placebo: hazard ratio [HR] = 0.506; 95% confidence interval [CI], 0.302-0.849; P = 0.009). Median time to PSA progression was more favorable with apalutamide than placebo (HR = 0.210; 95% CI, 0.124-0.357; P < 0.001). Median maximum percentages of PSA decline from baseline were 99.0% and 73.9% in the apalutamide and placebo groups, respectively. The most common adverse event (AE) was rash in the apalutamide group, with a higher rate than that in the placebo group (37.3% vs 9.1%). The most common grade 3 or 4 AEs were rash (12 [10.9%]) and hypertension (12 [10.9%]) for apalutamide. The efficacy and safety of apalutamide in the East Asian subgroup of the TITAN trial are consistent with the global results.

OBJECTIVETo compare the efficacy and safety of gefitinib or docetaxel in Chinese patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) who had failed previous platinum-based first-line chemotherapy.

METHODSWe retrospectively reviewed 222 Chinese NSCLC patients in the subgroup of INTEREST (gefitinib versus docetaxel in previously treated non-small cell lung cancer) study. Survival analysis was evaluated by Kaplan-Meier method, and Functional Assessment of Cancer Therapy-Lung (FACT-L) was used to compare the quality of life between gefitinib group and docetaxel group.

RESULTSA total of 222 patients were analyzed in this subgroup study. 107 patients were treated with gefitinib, and 115 patients treated with docetaxel. There were all balanced between the two groups in terms of sex, age, staging and pathology in patient characteristics. The median overall survival in the two groups was similar (11 months in the gefitinib group vs. 14.0 months in the docetaxel group, P = 0.783). The progression-free survival (PFS) was also similar between the two groups (median PFS: 3.4 months in gefitinib group vs. 3.8 months in docetaxel group, P = 0.214). The response rate in gefitinib group was significantly higher than that in the docetaxel group (21.9% vs. 9.1%, P = 0.016).

CONCLUSIONThe efficacy of gefitinib is similar with that of docetaxel in pretreated patients with locally advanced or metastatic NSCLC, however, gefitinib is more favorable in the tolerance and quality of life improvement.

OBJECTIVETo evaluate the safety and efficacy of gefitinib as second-line or even third-line treatment for previously treated patients with locally advanced or metastatic non-small cell lung cancer (NSCLC).

METHODS156 patients with locally advanced NSCLC which were about to undergo progression after previous chemotherapy were eligible for this study. The regimen was oral intake of gefitinib 250 mg once daily in the morning or afternoon until the disease progression or toxicity has become intolerable. The drug was provided by AstroZeneca Company by its Expanded Access Program.

RESULTS154 such patients were evaluable for response and toxicity assessment. The overall rate of objective response and disease control was 28.6% (44/154) and 89.6% (138/154). The median duration of response was 7. 5 months. The median time to disease progression (TTP) was 5. 1 months and the median overall survival time (OS) 10.0 months. The actuarial 1-year survival was 41. 0%. The response rate in adenocarcinoma was significantly higher than that in squamous carcinoma (P = 0. 026). The risk of disease progression in patients with squamous carcinoma was 1. 7 times as much as that of adenocarcinoma patients ( P = 0. 011) , and the risk of death in male was 2. 0 times as much as that in female ( P = 0. 002). At least one of these adverse events would be observed in 40.9% (63/154) of these patients, which, however was mild and reversible. Conclusion Gefitinib is effective and safe as a second-line or third-line treatment for previously treated patients with locally advanced or metastatic non-small cell lung cancer.

OBJECTIVETo evaluate the efficacy and safety of gefitinib for the treatment of advanced non-small cell lung cancer (NSCLC).

METHODS125 patients with advanced NSCLC who had failed or not tolerated or refused chemotherapy received 250 mg oral doses of gefitinib once daily until the disease progression or intolerable toxicity.

RESULTSA total of 125 NSCLC patients were studied, the overall response rate (RR) and the disease control rate (DCR) after administration of gefitinib were 35.2% (44/125) and 77.6% (97/125), respectively. The median progression-free survival and the median survival time were 5.8 and 11.2 months, respectively. The one-year survival rate was 40.5%. The response rate was significantly higher in females, adenocarcinoma and nonsmokers than that in males, non-adenocarcinoma and smokers (P < 0.05). The response rate did not show significant differences regarding ECOG score or previous treatment. The median progression-free survival was significantly longer in ECOG PS 0-1 and gefitinib effective patients than that in ECOG PS >or= 2 and gefitinib ineffective patients (P < 0.01). The median survival time was significantly longer in adenocarcinoma, nonsmokers and gefitinib effective patients than that in non-adenocarcinoma, smokers and gefitinib ineffective patients (P < 0.05). The most common side effects were rash (51.2%) and diarrhea (34.4%), but usually were mild.

CONCLUSIONGefitinib is effective and safe in the treatment of advanced NSCLC patients.

An 82-yr-old man was presented with fever and cough accompanied by generalized erythematous rash. He had taken mexiletine for 5 months, as he had been diagnosed with dilated cardiomyopathy and ventricular arrhythmia. Laboratory studies showed peripheral blood eosinophilia and elevated liver transaminase levels. Chest radiographs showed multiple nodular consolidations in both lungs. Biopsies of the lung and skin lesions revealed eosinophilic infiltration. After a thorough review of his medication history, mexiletine was suspected as the etiologic agent. After discontinuing the mexiletine and starting oral prednisolone, the patient improved, and the skin and lung lesions disappeared. Subsequently, mexiletine was confirmed as the causative agent based on a positive patch test. Drug-induced hypersensitivity syndrome is a severe adverse reaction to drugs and results from treatment with anticonvulsants, allopurinol, sulfonamides, and many other drugs. Several cases of mexiletine-induced hypersensitivity syndrome have been reported in older Japanese males with manifestation of fever, rash, peripheral blood eosinophilia, liver dysfunction without other organ involvement. Here, we report a case of mexiletine-induced hypersensitivity syndrome which presented as eosinophilic pneumonia in a Korean male.

OBJECTIVETo evaluate the efficacy and safety of gefitinib as maintenance therapy for patient with advanced non-small lung cancer (NSCLC).

METHODSFrom Oct. 2002 to Apr. 2006, 173 patients with advanced NSCLC received oral gefitinib 250 mg per day after completion of induction chemotherapy (62 patients, maintenance therapy group) or recurrence after one or more regimens of chemotherapy (111 patients, recurrent group). Median survival (MS) and progress free survival (PFS) were calculated using the Kaplan-Meier method, and Cox regression analysis was used to analyze the difference between the sub-groups stratified by smoking, pathological type, liver metastasis and gefitinib treatment result.

RESULTSMS of maintenance therapy group and recurrent group were 25.0 months (95% CI: 19.3-30.7) and 12.5 months (95% CI: 9.3-15.7), respectively. There was a statistically significant difference between the above two groups (P = 0.0004). PFS of maintenance therapy group and recurrent group was 16.5 months (95% CI: 8.7-24.3) and 9.2 months (95% CI: 7.5-10.9), respectively. There was also a statistically significant difference between these two groups (P = 0. 0000). It was found that median MS in maintenance therapy group was significantly correlated with smoking status, pathology type, liver metastasis and objective response of gefitinib.

CONCLUSIONMaintenance therapy with gefitinib after induction chemotherapy may improve overall survival in patient with non-small cell lung cancer.

OBJECTIVEBrain metastasis is frequently found in patient with advanced non-small cell lung cancer. Gefitinib is a inhibitor of epidermal growth factor receptor and can be used for the treatment of advanced non-small cell lung cancer (NSCLC). The aim of this study was to evaluate the antitumor efficacy of Gefitinib in advanced NSCLC patients with brain metastasis.

METHODSForty-four consecutive NSCLC patients with brain metastases were treated with gefitinib, which was administered orally at daily dose of 250 mg. Of these patients, 30 had been treated with WBRT and 42 received chemotherapy one month before enrolled into the study.

RESULTSPartial response (PR) was observed in 14 patients (31.8%), stable disease (SD) in 21 (47.7%) with an overall disease control rate of 79.5%. Median progression-free survival (PFS) was 9 months and median overall survival (OS) was 13.0 months. The difference in disease control rate between the patients who had previous WBRT and those without was not significant (P = 0.566). The toxicity is mild and tolerable.

CONCLUSIONOur data shows that Gefitinib is safe and may be effective on brain metastasis, which may become an alternative treatment option for the patient with advanced NSCLC.

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 study the anti-tumor effect and toxicity of Gefitinib in the treatment of patients with advanced non-small-cell lung cancer (NSCLC).

METHODSFrom August 2003 to February 2005, 50 advanced NSCLC patients were treated with Gefitinib orally 250 mg once per day. All patients were stratified by gender, histology, smoking history and chemotherapy cycles. The response was evaluated as the time to tumor progression (TTP) and the median survival time (MST). Quality of life (QoL) was assessed using the Chinese version of European Organization for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-30 and the brief fatigue inventory (BFI).

RESULTSEven though none of these patients achieved complete response, 16.0% of them still gave partial response. Clinical benefit rate was 60.0% in this series. Objective tumor response was correlated with gender, pathological type and smoking history. Multivariate analysis suggested that gender, chemotherapy cycles and QoL obviously correlated with the tumor response. Twenty of these 50 patients (40.0%, 20/50) were still alive when the follow-up ended in February 2005. The 1-year survival rate was 14.0%. TTP and MST was 5 and 6 months, respectively, in patients who had been dead. The median survival time of patients who are still alive was 13 months. The mean survival time of PR patients was more than 9 months. The rate of QoL improvement was 58.0% and the rate of fatigue remission was 52.6%. The mean time to symptom improvement was 15 days. The main toxicities were reversible grade I or grade II skin rash and diarrhea. Two patients who developed radiation pneumonitis during previous radiotherapy became more deteriorated after Gefitinib treatment.

CONCLUSIONGefitinib is effective and tolerated by the patients with advanced non-small cell lung cancer. It may remarkablely improve their symptoms and quality of life.
