| Abstract | BACKGROUND: Despite the efficacy of gemcitabine-platinum regimen, the outcome of patients with recurrent and/or metastatic nasopharyngeal carcinoma (RM NPC) is poor. A phase II trial was conducted to determine the efficacy of erlotinib, given as maintenance therapy after gemcitabine-platinum chemotherapy in patients with RM NPC. PATIENTS AND METHODS: Patients were treated with gemcitabine 1000 mg/m on days 1 and 8 as well as cisplatin 70 mg/m on day 1 (or carboplatin area under curve 5 on day 1, if contraindication to cisplatin) 3 weeks. After 6 chemotherapy cycles (or before in case of progression), patients were switched to erlotinib 150 mg/d 4 weeks. Primary end point was time to progression in patients without progressive disease after 6 chemotherapy cycles and treated with maintenance erlotinib. Epstein-Barr virus DNA plasma levels, measured using quantitative real-time polymerase chain reaction, were correlated with outcome. RESULTS: Of 20 enrolled patients, 19 patients received 96 chemotherapy cycles. Fifteen patients were switched to erlotinib and received 36 cycles (range: 1 to 6 cycles). Safety profiles observed with the chemotherapy combination and erlotinib were those expected. Of 12 patients evaluable for response to erlotinib, all progressed except 3 patients (25%) who had stable disease for 3, 4, and 7 months, respectively. Median time to progression was 6.9 months for 13 patients without progressive disease after 6 chemotherapy cycles and treated with erlotinib. No correlation was identified between Epstein-Barr virus DNA plasma levels and clinical outcome. CONCLUSIONS: Maintenance or second-line therapy with erlotinib after chemotherapy was not effective in RM NPC. Historical comparison with patients treated with the same chemotherapy alone until progression suggests that it may be detrimental to stop chemotherapy after 6 cycles if disease did not progress. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
