Primary Outcome Measures :
  1. Progression-free survival [ Time Frame: From date of randomization to the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years ]
    The primary endpoint of this study is progression-free survival. This is defined as the time from randomization to disease progression or death due to any cause.

Secondary Outcome Measures :
  1. Overall survival [ Time Frame: From date of randomization to death from any cause, assessed up to 3 years ]
    Overall survival is defined as the time from randomization to death due to any cause.

  2. Response rate [ Time Frame: Every 6 weeks ]
    Response assessment will be performed according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1 every 2 cycles (6 weeks) of treatment.

  3. Quality of life [ Time Frame: Every 6 weeks ]
    Quality of life of patient will be evaluated using EUROQOL(EQ-5D). Evaluation of quality of life will be performed every 2 cycles (6 weeks) from baseline to the end of treatment.

  4. Number of Adverse Events [ Time Frame: Every 3 weeks ]
    Monitoring for safety and toxicity will be performed every cycle (3 weeks) of chemotherapy and whenever patients have problems.
