The present case is a patient with advanced non-small cell lung cancer (NSCLC) who developed leukoencephalopathy following radiotherapy and gefitinib treatments. There are rarely reports of such incidences because the median survival period of advanced NSCLC is only ten months. The features of leukoencephalopathy in this case were atypical for radiation leukoencephalopathy, so it was suspected that the leukoencephalopathy was associated with gefitinib.

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.

OBJECTIVEEpidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) such as gefitinib and erlotinib are used as standard 2(nd)/3(rd) line therapy in previously treated advanced non-small cell lung cancer (NSCLC). However, the optimal treatment for patients who experienced disease progression after chemotherapy and EGFR-TKI is unclear. The aim of this study was to explore the efficacy and safety of a salvage chemotherapy in advanced NSCLC patients who failed the previous treatment of platinum-based chemotherapy and EGFR-TKI.

METHODSClinicopathological data of 55 cases of advanced NSCLC patients who failure of first-line platinum-based chemotherapy and subsequent treatment with TKI were collected and analyzed. The patients were of PS = 0-2, and with normal vital organ function. Patients received salvage chemotherapy until disease progression or unacceptable toxicity or the patient refused to continue receiving treatment. A chart review assessed the key outcomes including the objective response rate (ORR), disease control rate (DCR) and progression-free survival (PFS).

RESULTSFifty-five patients were enrolled in this study from march 2007 to october 2009. The median age of patients was 55 years (range: 34 - 72), 60.0% were males, PS 0-1 patients were 65.5%, stage IV patients were 100%; 34.5% had a TKI treatment duration ≥ 6 months. Twenty-four patients received pemetrexed as salvage chemotherapy, 21 received docetaxal and 10 had other chemotherapy. All patients were evaluable for efficacy. Among them, 7 (12.7%) patients achieved PR, 21 (38.2%) patients SD, and 27 (49.1%) patients PD, with ORR of 12.7% and DCR of 50.9%. The median follow-up duration was 5.5 months, and the median PFS was 2.0 months. The ORR and PFS were not significantly related with gender, PS and chemotherapy regimens (all P > 0.05), but patients with EGFR-TKI treatment ≥ 6 months achieved a significantly better ORR and DCR than those < 6 months (ORR: 21.1% vs. 8.3%, P = 0.012; DCR: 73.3% vs. 38.9%, P = 0.017), mPFS was significant longer in the patients received ≥ 6 months of EGFR-TKI (4.5 vs. 2.0 months, P = 0.008). The toxicity was acceptable and there were no treatment-related deaths.

CONCLUSIONAdvanced NSCLC patients failed with the previous treatment of first-line platinum-based chemotherapy and EGFR-TKI may benefit from salvage chemotherapy, especially in patients who received ≥ 6 months of EGFR-TKI. The toxicity of the salvage chemotherapy is acceptable.

Erlotinib is accepted as a standard second-line chemotherapeutic agent in patients with non-small cell lung cancer who are refractory or resistant to first-line platinum-based chemotherapy. There has been no previous report of bowel perforation with or without gastrointestinal metastases related to erlotinib in patients with non-small cell lung cancer. The exact mechanism of bowel perforation in patients who received erlotinib remains unclear. In this report, we report the first case of enterocutaneous fistula in a female patient with metastatic non-small cell lung cancer 9 months, following medication with erlotinib as second-line chemotherapy.

BACKGROUNDThe preclinical experiments and several clinical studies showed icotinib, an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, in Chinese patients with advanced non-small cell lung cancer (NSCLC) who failed previous chemotherapy. We performed a retrospective study of the efficacy and safety of icotinib monotherapy in a different and more recent sample of Chinese patients.

METHODSThe clinical data of 149 patients with advanced NSCLC who were admitted to Zhejiang Cancer Hospital from August 1, 2011 to July 31, 2012 were retrospectively analyzed. All patients were given icotinib treatment after the failure of previous chemotherapy. Univariate and multivariate analyses were conducted based on the Kaplan Meier method and Cox proportional hazards model.

RESULTSThe objective response rate was 33/149 and disease control rate was 105/149. No complete response occurred. Median progression free survival (PFS) with icotinib treatment was 5.03 months (95% CI: 3.51 to 6.55). Median overall survival was 12.3 months (95% CI: 10.68 to 13.92). Multivariate analysis showed that the mutation of EGFR and one regimen of prior chemotherapy were significantly associated with longer PFS. At least one drug related adverse event was observed in 65.8% (98/149) of patients, but mostly grade 1 or 2 and reversible and none grade 4 toxicity.

CONCLUSIONSIcotinib monotherapy is an effective and well tolerated regimen for Chinese patients with NSCLC after the failure of chemotherapy. It is a promising agent and further study with icotinib in properly conducted trials with larger patient samples and other ethnic groups is warranted.

OBJECTIVETo investigate the antitumor efficacy, time to tumor progression (TTP) and toxicity of gefitinib (Iressa, ZD1839)--a selective epidermal growth factor receptor tyrosine kinase inhibitor in the treatment of male patients with advanced non-small-cell lung cancer (NSCLC). Methods Fifty-nine male patients with stage IV NSCLC orally took Iressa 250 mg once daily until disease progression or intolerable toxicity ocurred. They were required to conduct tumor-evaluation before the treatment, one month after Iressa administration and then every other month.

RESULTSOf these 59 patients, no complete regression was observed, 23.7% had partial response (PR), and 16.9% stable disease (SD) with a disease control (PR + SD) rate of 40.7%, while 59.3% had progress of disease (PD). The median time to tumor progression (TTP) was 1.8 months, and the median survival was 8.5 months. Fifty-nine patients were followed up over one year, 35 over two year and 15 over three year, and the 1-, 2- and 3-year survival rates were 42.4%, 17.1% and 13.3%. The most common adverse effects were grade 1 or 2 skin reaction and diarrhea.

CONCLUSIONIressa is effective in antitumor for the male patients with advanced non-small-cell lung cancer, and can improve the survival for those responsing to gefitinib. The adverse effects are usually tolerable.
