Brief Summary:
Ketogenic diet has shown auxiliary effect on treatment of malignant tumors require high glucose consumption. This study is designed to evaluate the safety and efficacy of ketogenic diet adjunctive to high dose methotrexate(HD-MTX) chemotherapy for primary central nervous system lymphoma (PCNSL).

Condition or disease Intervention/treatment Phase
Primary Central Nervous System Lymphoma Dietary Supplement: ketogenic diet Dietary Supplement: Routine diet Phase 1 Phase 2

Detailed Description:
In a pilot study of primary central nervous system(CNS) lymphoma patients, ketogenic diet was given in adjunction with standard HD-MTX chemotherapy as interventional group; standard HD-MTX is given with routine diet as control group. The primary endpoint is the safety of ketogenic diet in PCNSL patients receiving chemotherapy, secondary endpoints include rate of complete remission, remission time, rate of tumor relapse and overall survival.

Arm Intervention/treatment
Experimental: ketogenic diet group
Ketogenic diet is given in combination to standard HD-MTX chemotherapy to primary central nervous system lymphoma patients. Blood ketone is kept no less than 2mmol/L during the initial 4 cycles of chemotherapy. The adverse events is monitored and recorded. Tumor response is evaluated and recorded.
Dietary Supplement: ketogenic diet
Ketogenic diet is given to maintain blood ketone level above 2 mmol/L.

Active Comparator: routine diet group
Standard HD-MTX chemotherapy is given with routine diet.Blood ketone is measured and recorded. The adverse events is monitored and recorded. Tumor response is evaluated and recorded.
Dietary Supplement: Routine diet
Routine diet is given without blood ketone requirement

Primary Outcome Measures :
  1. Number of participants with treatment related adverse events as assessed by CTCAE v4.0 [ Time Frame: Two years ]
    The number and incidence (%) of treatment related adverse events among participants

Secondary Outcome Measures :
  1. The chemosensitivity of tumor [ Time Frame: Two years ]
    The rate of complete remission after treatment assessed according to serial contrast Magnetic Resonance Imaging (MRI)

  2. Long term effect of chemotherapy [ Time Frame: Two years ]
    The average time from complete remission of tumor to relapse

  3. overall survival [ Time Frame: Three years ]
    Participants will be followed until reported death to calculate overall survival

  4. Quality of life [ Time Frame: Two years ]
    Short Form 36 Questionnaire will be used to assess patients' quality of life
