Introduction: With the availability of three prognostic scores in Peripheral T-Cell Lymphoma (PTCL)-International Prognostic Index (IPI), International Peripheral T-Cell Lymphoma Project (IPTCLP), and Prognostic Index for PTCL-Unspecified (PIT), we intended to find out usefulness of each of them in prognostication of patients. Objectives were to know the clinicopathological profile and to analyze the effectiveness of these prognostic scores and their individual parameters in predicting Complete Remission (CR) rates, Progression Free Survival (PFS), and Overall Survival (OS) in PTCL. Materials and Methods: All 55 patients were treated as per institute chemotherapeutic protocols. Response assessment was done by Cheson’s criteria. At baseline, patients were risk stratified with the three scores into low, low- and high-intermediate, and high-risk groups. Outcomes − CR and survival − PFS and OS were analyzed and compared in the risk groups as stratified by the three prognostic scores. Clinical and pathological details were also analyzed. Results: For PFS estimation, IPI and IPTCLP scores proved be the best prognostic tools. For OS, IPTCLP score emerged to be the single best prognostic tool. CR correlated with Ann Arbor stage of disease and IPI score. Conclusion: PTCL NOS (Not Otherwise Specified) was the most common histological subtype. IPI score correlated the best with CR reflecting as PFS, but was not related statistically with OS in the local population. IPTCLP score has consistent correlation with prognosis more so with OS than PFS, but no relationship with CR rate.
