* Indolent Non-Hodgkin lymphoma types have a relatively good prognosis with a median survival as long as 20 years, but they usually are not curable in advanced clinical stages. Early-stage (stage I and stage II) indolent Non-Hodgkin lymphoma can be effectively treated with radiation therapy alone. Most of the indolent types are nodular (or follicular) in morphology.
*The survival rate has steadily improved over the last 2 decades, thanks to improvements in medical and nursing care, the advent of novel therapeutic strategies (ie, [[monoclonal antibodies]]), validation of biomarkers of response, and the implementation of tailored treatment.
* The aggressive type of Non-Hodgkin lymphoma has a shorter natural history, but a significant number of these patients can be cured with intensive combination chemotherapy regimens.
*The prognosis for patients with NHL depends on the following factors:<ref name="pmid21224370">{{cite journal| author=Abla O, Weitzman S, Blay JY, O'Neill BP, Abrey LE, Neuwelt E et al.| title=Primary CNS lymphoma in children and adolescents: a descriptive analysis from the International Primary CNS Lymphoma Collaborative Group (IPCG). | journal=Clin Cancer Res | year= 2011 | volume= 17 | issue= 2 | pages= 346-52 | pmid=21224370 | doi=10.1158/1078-0432.CCR-10-1161 | pmc=4058714 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21224370  }} </ref>
* In general, with modern treatment of patients with Non-Hodgkin lymphoma, overall survival at 5 years is over 60%. Of patients with aggressive Non-Hodgkin lymphoma, more than 50% can be cured. The vast majority of relapses occur in the first 2 years after therapy. The risk of late relapse is higher in patients who manifest both indolent and aggressive histologies.
**Tumor histology
* While indolent Non-Hodgkin lymphoma is responsive to [[immunotherapy]], [[radiation therapy]], and [[chemotherapy]], a continuous rate of relapse is usually seen in advanced stages. Patients, however, can often be re-treated with considerable success as long as the disease histology remains low grade. Patients who present with or convert to aggressive forms of Non-Hodgkin lymphoma may have sustained complete remissions with combination chemotherapy regimens or aggressive consolidation with marrow or stem cell support.

====International Prognostic Index (IPI)====
The [[International Prognostic Index]], or IPI, is the most widely used prognostic system for Non-Hodgkin's lymphoma. This system uses 5 factors:
*The International Prognostic Index (IPI), which was originally designed as a prognostic factor model for aggressive non Hodgkin lymphoma (NHL) appears to be useful for predicting the outcome of patients with low-grade lymphoma and [[mantle cell lymphoma]].<ref name="pmid21224370">{{cite journal| author=Abla O, Weitzman S, Blay JY, O'Neill BP, Abrey LE, Neuwelt E et al.| title=Primary CNS lymphoma in children and adolescents: a descriptive analysis from the International Primary CNS Lymphoma Collaborative Group (IPCG). | journal=Clin Cancer Res | year= 2011 | volume= 17 | issue= 2 | pages= 346-52 | pmid=21224370 | doi=10.1158/1078-0432.CCR-10-1161 | pmc=4058714 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21224370  }} </ref><ref name="pmid26384083">{{cite journal| author=Shalabi H, Angiolillo A, Vezina G, Rubenstein JL, Pittaluga S, Raffeld M et al.| title=Prolonged Complete Response in a Pediatric Patient With Primary Peripheral T-Cell Lymphoma of the Central Nervous System. | journal=Pediatr Hematol Oncol | year= 2015 | volume= 32 | issue= 8 | pages= 529-34 | pmid=26384083 | doi=10.3109/08880018.2015.1074325 | pmc=4942274 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=26384083 }} </ref>
:*Age
*This index is used to identify patients at high risk of relapse, based on specific sites of involvement, including [[Bone marrow abnormality|bone marrow]], [[Brain abscess|CNS]], liver, testis, lung, and spleen.
:*[[Lactate dehydrogenase]] level (a blood test)
*Clinical features included in the IPI that are independently predictive of survival include the following:
:*Performance status
**Age - Younger than 60 years versus older than 60 years
:*Clinical stage
**LDH level - Within the reference range versus elevated
:*Sites of extranodal disease
**Performance status - Eastern Cooperative Oncology Group ( ECOG) grade 0-1 versus 2-4
 
**Ann Arbor stage - Stage I-II versus III-IV
However, it should be noted that the IPI was developed prior to the introduction of [[rituximab]]. As [[rituximab]] has become a standard part of therapy for [[B-cell]] Non-Hodgkin lymphoma, the impact on the prognostic value of the IPI is unclear.
**Number of extranodal sites - Zero to 1 versus more than 1
 
*With this model, relapse-free and overall survival rates at 5 years are as follows:
====Follicular Lymphoma International Prognostic Index (FLIPI)====
**0-1 risk factors - 75%
For the subtype of Non-Hodgkin lymphoma known as [[follicular lymphoma]], a modified version of the IPI called the FLIPI ([[International Prognostic Index|follicular lymphoma international prognostic index]]) has been developed. The factors which figure into the FLIPI are age, clinical stage, [[lactate dehydrogenase]] level, [[hemoglobin]] level, and number of nodal sites involved. As with the IPI, the FLIPI was developed and validated prior to the widespread use of [[rituximab]], so the same caveats apply as were mentioned with the IPI above.
**2-3 risk factors - 50%

Overview

Common complications of non-Hodgkin lymphoma include lymphadenopathy, disseminated intravascular coagulation, superior vena cava (SVC) syndrome, autoimmune hemolytic anemia and infection. The indolent non-Hodgkin lymphoma types are associated with a relatively good prognosis. The 5-year relative survival rate of patients with NHL is 71.4%.

Natural History

Complications

Common complications of non-Hodgkin lymphoma include:[1]

Prognosis

  • The 5-year relative survival rate of patients with NHL is 71.4%.[2]
  • The survival rate has steadily improved over the last 2 decades, thanks to improvements in medical and nursing care, the advent of novel therapeutic strategies (ie, monoclonal antibodies), validation of biomarkers of response, and the implementation of tailored treatment.
  • The prognosis for patients with NHL depends on the following factors:[2]

Prognostic Indexes

International Prognostic Index (IPI)

  • The International Prognostic Index (IPI), which was originally designed as a prognostic factor model for aggressive non Hodgkin lymphoma (NHL) appears to be useful for predicting the outcome of patients with low-grade lymphoma and mantle cell lymphoma.[2][3]
  • This index is used to identify patients at high risk of relapse, based on specific sites of involvement, including bone marrow, CNS, liver, testis, lung, and spleen.
  • Clinical features included in the IPI that are independently predictive of survival include the following:
    • Age - Younger than 60 years versus older than 60 years
    • LDH level - Within the reference range versus elevated
    • Performance status - Eastern Cooperative Oncology Group ( ECOG) grade 0-1 versus 2-4
    • Ann Arbor stage - Stage I-II versus III-IV
    • Number of extranodal sites - Zero to 1 versus more than 1
  • With this model, relapse-free and overall survival rates at 5 years are as follows:
    • 0-1 risk factors - 75%
    • 2-3 risk factors - 50%
    • 4-5 risk factors - 25%
