Effect of Expression of CD74 and VEGF on Outcome of Treatment in Patients With Malignant Pleural Mesothelioma

Effect of Expression of CD74 and VEGF on Outcome of Treatment in Patients With Malignant Pleural Mesothelioma Receiving Pemetrexed/Platinum Protocol

This is a prospective study evaluating the effect of expression of CD74 and VEGF on outcome of treatment in patients with malignant pleural mesothelioma receiving Pemetrexed/Platinum protocol. The paraffin blocks of the patients will be tested for CD74 and VEGF before starting treatment using IHC and the results will be correlated with the outcome of treatment during evaluation.

Inclusion Criteria:

1. Histologic or cytologic diagnosis of malignant pleural Mesothelioma
2. No prior chemotherapy.
3. ECOG less than or equal to 2 .
4. Measurable disease according to the requirements of SWOG criteria.
5. Age ≥ 19 years .
6. Estimated life expectancy of at least 12 weeks .
7. Adequate bone marrow reserve (white blood cells [WBC] ≥ 3.5 × 109 /L, neutrophils ≥ 1.5 × 109 /L, platelets ≥ 100 × 109 /L, and hemoglobin ≥ 9.0 gm/dL).

Exclusion Criteria:

1. Presence of central nervous system metastases.
2. Inadequate liver function (bilirubin > 1.5 times upper normal limit [UNL] and alanine transaminase [ALT] or aspartate transaminase [AST] > 3.0 UNL or up to 5.0 UNL in the presence of hepatic metastases).
3. Inadequate renal function (creatinine > 1.25 times UNL, creatinine clearance < 50mL/min).
4. Serious concomitant systemic disorder incompatible with the study.
5. Second primary malignancy (except in situ carcinoma of the cervix, adequately treated basal cell carcinoma of the skin, T1 vocal cord cancer in remission, or prior malignancy treated more than 5 years prior to enrollment without recurrence).
6. Pregnancy
