Description

Non-Hodgkin Lymphoma of the B-cell type (NHL) is a cancer that affects many people worldwide, including those in Pakistan. There was little knowledge of the Clinicopathological features of B-cell NHL in our group. This study evaluated the most common subtypes of B-cell NHL as well as the clinical spectrum.

A lymphocyte neoplasm is lymphoma. Hodgkin Lymphoma (HL) and Non-Hodgkin Lymphoma are the two primary subtypes of lymphomas (NHL). NHL can also be divided into B-cell and T-cell subtypes. Low- and high-grade B-cells have diverse genetic and predictive characteristics. All diagnosed cases of B-cell NHL were included in the study in accordance with the World Health Organization (WHO) Classification of Tumors of Hematopoietic and Lymphoid Tissues. Regardless of age, participants from both genders were included in this study. Over the past few decades, cancer incidence has climbed by around 30% worldwide, and NHL accounts for approximately 4-6% of all malignancies. In the United States, NHL ranks seventh in cancer-related mortality.

NHL is the sixth most lethal and seventh most prevalent cancer worldwide. 2018 saw an estimated 509,600 new cases of NHL identified globally, making up 2.8% of all cancer diagnoses, and an estimated 248,700 deaths worldwide, making up 2.6% of all oncological fatalities, according to current data. 2020 saw an anticipated 77,200 new NHL diagnoses in the US, making up 4.3% of all cancer diagnoses. NHL encompasses a broad spectrum of diseases, from slow-growing to malignant cancers. A pathological examination and categorization using the WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues are necessary for a precise diagnosis of NHL.

The patients were 47.73 ± 20.44 years old on average. There were 369 men (67.34%) and 179 females (32.66%). Diffuse Large B-Cell Lymphoma (DLBCL) (58.94%), Chronic Lymphocytic Leukaemia /Small Lymphocytic Lymphoma (CLL/SLL) (13.14%), Burkitt lymphoma (9.85%), and precursor B-cell lymphoblastic lymphoma (5.11%) were the most common types of B-cell NHL. High-grade B-cell NHL was more prevalent (77.01%) than low-grade B-cell NHL (22.99%). Nodal involvement was detected in 62.04% of patients. The gastrointestinal tract (GIT) was the most frequent extranodal site (48.29%) while the cervical area (62.04%) was the most frequent nodal site of involvement.

Epstein - Barr virus (EBV) may be connected to the pathogenesis of NHL, according to mounting evidence. The prevalence of these instances is greater among the elderly due to age-related alterations in the immune system and extended latency of EBV infection. Poorly preserved biopsies, tru-cut samples that were undiagnosable, lymphomas that couldn’t be classified, cytological specimens, and bone marrow biopsies were all eliminated from the research.

The most often diagnosed subtype is Diffuse Large B Cell Lymphoma (DLBCL), which is followed by CLL/ SLL, Burkitt’s lymphoma, and Pre B-Lymphoblastic Leukemia. Other disease subtypes accounted for less than 4% of cases. The cervical area had a greater rate of nodal involvement, but the GIT had a higher proportion of extranodal involvement. Lymphoma incidence has significantly increased in elderly adults, especially those over 60 years old. The prevalence of high-grade B-cell NHL exceeds that of low-grade B-cell NHL. CLL/SLL is the most prevalent kind of low- grade B-cell NHL, followed by FL and MZL. The most frequent high-grade lymphomas include Burkitt’s lymphoma, pre-B LBL, and DLBCL.

In older age groups, B-cell NHL is more common. The GIT was an extranodal location, but the cervical area was the most frequent nodal site. DLBCL was the most often reported subtype, followed by CLL/SLL and Burkitt lymphoma. Compared to low-grade B-cell NHL, high-grade B-cell NHL is more common.
