Overview

bull Epidemiology

bull Clinical presentation

bull Diagnosis

bull Staging

bull Three important types of lymphoma

How Cancer Develops

bull Normal cells are programmed to multiply die when theyrsquore old

bull Signals to multiply and die are controlled by specific genes

bull Mutations can occur in these genesbull If enough mutations occur in genes

controlling growth or cell death a cell begins to multiply uncontrollably

bull The cell has then become cancerous or ldquomalignantrdquo

Features common to cancer cells

bull Growth in the absence of ldquogordquo signals

bull Growth despite ldquostoprdquo signals

bull Locally invasive growth and metastases to distant sites

Bone Marrow

bull Present in the soft inner part of some bones such as the skull shoulder blade ribs pelvis and backbones (Occupies central cavity of bone)

bull The bone marrow is made up of blood-forming stem cells lymphoid tissue fat cells and supporting tissues that aid the growth of blood forming cells

Bone Marrow

bull Spongy tissue where development of all types of blood cells takes place

bull All bones have active marrow at birth

bull Adulthood - vertebrae hip shoulders ribs breast and skull contain marrow

Hematopoietic Malignancies

1048708 Lymphoma is a general term for

hematopoietic solid malignancies of

the lymphoid series

1048708 Leukemia is a general term for liquid

malignancies of either the lymphoid

or the myeloid series

Conceptualizing lymphoma

bull neoplasms of lymphoid origin typically causing lymphadenopathy

bull leukemia vs lymphoma

bull lymphomas as clonal expansions of cells at certain developmental stages

What is Lymphoma

bull Lymphomas are cancers that begin by the ldquomalignant transformationrdquo of a lymphocyte in the lymphatic system

bull Many lymphomas are known to be due to specific genetic mutations

bull Follicular lymphoma due to overexpression of BCL-2 (gene that blocks programmed cell death)

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

bull most common type of ldquoaggressiverdquo lymphoma

bull usually symptomatic

bull extranodal involvement is common

bull cell of origin germinal center B-cell

bull treatment should be offered

bull curable in ~ 40

B-Cell Lymphoma (80)

bull B-Cells help make antibodies which are proteins that attach to and help destroy antigens

bull Lymphomas are caused when a mutation arises during the B-cell life cycle

bull Various different lymphomas can occur during several different stages of the cyclendash Follicular lymphoma which is a type of B-cell

lymphoma is caused by a gene translocation which results in an over expressed gene called BCL-2 which blocks apoptosis

T-Cell Lymphoma (15)

bull The T-cells are born from stem cells similar to that of B-cells but mature in the thymus

bull They help the immune system work in a coordinated fashionndash These types of lymphomas are categorized

How Cancer Develops

bull Normal cells are programmed to multiply die when theyrsquore old

bull Signals to multiply and die are controlled by specific genes

bull Mutations can occur in these genesbull If enough mutations occur in genes

controlling growth or cell death a cell begins to multiply uncontrollably

bull The cell has then become cancerous or ldquomalignantrdquo

Features common to cancer cells

bull Growth in the absence of ldquogordquo signals

bull Growth despite ldquostoprdquo signals

bull Locally invasive growth and metastases to distant sites

Bone Marrow

bull Present in the soft inner part of some bones such as the skull shoulder blade ribs pelvis and backbones (Occupies central cavity of bone)

bull The bone marrow is made up of blood-forming stem cells lymphoid tissue fat cells and supporting tissues that aid the growth of blood forming cells

Bone Marrow

bull Spongy tissue where development of all types of blood cells takes place

bull All bones have active marrow at birth

bull Adulthood - vertebrae hip shoulders ribs breast and skull contain marrow

Bone Marrow AspirationBiopsy

Hematopoietic Malignancies

1048708 Lymphoma is a general term for

hematopoietic solid malignancies of

the lymphoid series

1048708 Leukemia is a general term for liquid

malignancies of either the lymphoid

or the myeloid series

Conceptualizing lymphoma

bull neoplasms of lymphoid origin typically causing lymphadenopathy

bull leukemia vs lymphoma

bull lymphomas as clonal expansions of cells at certain developmental stages

What is Lymphoma

bull Lymphomas are cancers that begin by the ldquomalignant transformationrdquo of a lymphocyte in the lymphatic system

bull Many lymphomas are known to be due to specific genetic mutations

bull Follicular lymphoma due to overexpression of BCL-2 (gene that blocks programmed cell death)

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

bull curable in ~ 40

B-Cell Lymphoma (80)

bull B-Cells help make antibodies which are proteins that attach to and help destroy antigens

bull Lymphomas are caused when a mutation arises during the B-cell life cycle

bull Various different lymphomas can occur during several different stages of the cyclendash Follicular lymphoma which is a type of B-cell

lymphoma is caused by a gene translocation which results in an over expressed gene called BCL-2 which blocks apoptosis

T-Cell Lymphoma (15)

Bone Marrow

bull Present in the soft inner part of some bones such as the skull shoulder blade ribs pelvis and backbones (Occupies central cavity of bone)

bull The bone marrow is made up of blood-forming stem cells lymphoid tissue fat cells and supporting tissues that aid the growth of blood forming cells

Bone Marrow

bull Spongy tissue where development of all types of blood cells takes place

bull All bones have active marrow at birth

Conceptualizing lymphoma

bull neoplasms of lymphoid origin typically causing lymphadenopathy

bull leukemia vs lymphoma

bull lymphomas as clonal expansions of cells at certain developmental stages

What is Lymphoma

bull Lymphomas are cancers that begin by the ldquomalignant transformationrdquo of a lymphocyte in the lymphatic system

bull Many lymphomas are known to be due to specific genetic mutations

bull Follicular lymphoma due to overexpression of BCL-2 (gene that blocks programmed cell death)

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

malignancies of either the lymphoid

or the myeloid series

Conceptualizing lymphoma

bull neoplasms of lymphoid origin typically causing lymphadenopathy

bull leukemia vs lymphoma

bull lymphomas as clonal expansions of cells at certain developmental stages

What is Lymphoma

bull Lymphomas are cancers that begin by the ldquomalignant transformationrdquo of a lymphocyte in the lymphatic system

bull Many lymphomas are known to be due to specific genetic mutations

bull Follicular lymphoma due to overexpression of BCL-2 (gene that blocks programmed cell death)

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

Hematopoietic Malignancies

1048708 Lymphoma is a general term for

hematopoietic solid malignancies of

the lymphoid series

1048708 Leukemia is a general term for liquid

malignancies of either the lymphoid

or the myeloid series

Conceptualizing lymphoma

bull neoplasms of lymphoid origin typically causing lymphadenopathy

bull leukemia vs lymphoma

bull lymphomas as clonal expansions of cells at certain developmental stages

What is Lymphoma

bull Lymphomas are cancers that begin by the ldquomalignant transformationrdquo of a lymphocyte in the lymphatic system

bull Many lymphomas are known to be due to specific genetic mutations

bull Follicular lymphoma due to overexpression of BCL-2 (gene that blocks programmed cell death)

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

bull curable in ~ 40

B-Cell Lymphoma (80)

bull B-Cells help make antibodies which are proteins that attach to and help destroy antigens

bull Lymphomas are caused when a mutation arises during the B-cell life cycle

bull Various different lymphomas can occur during several different stages of the cyclendash Follicular lymphoma which is a type of B-cell

lymphoma is caused by a gene translocation which results in an over expressed gene called BCL-2 which blocks apoptosis

T-Cell Lymphoma (15)

What is Lymphoma

bull Lymphomas are cancers that begin by the ldquomalignant transformationrdquo of a lymphocyte in the lymphatic system

bull Many lymphomas are known to be due to specific genetic mutations

bull Follicular lymphoma due to overexpression of BCL-2 (gene that blocks programmed cell death)

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

What is the Lymphatic System

bull Made up of organs such as the tonsils spleen liver bone marrow and a network of lymphatic vessels that connect glands called lymph nodes

bull Lymph nodes located throughout the bodybull Lymph nodes filter foreign particles out of the

lymphatic fluid bull Contain B and T lymphocytes

Lymphatic System

bull Lymph nodes act as a filter to remove bacteria viruses and foreign particles

bull Most people will have had ldquoswollen glandsrdquo at some time as a response to infection

B-Cell Lymphoma (80)

bull B-Cells help make antibodies which are proteins that attach to and help destroy antigens

bull Lymphomas are caused when a mutation arises during the B-cell life cycle

bull Various different lymphomas can occur during several different stages of the cyclendash Follicular lymphoma which is a type of B-cell

lymphoma is caused by a gene translocation which results in an over expressed gene called BCL-2 which blocks apoptosis

T-Cell Lymphoma (15)

bull The T-cells are born from stem cells similar to that of B-cells but mature in the thymus

bull They help the immune system work in a coordinated fashionndash These types of lymphomas are categorized

Non-Hodgkinrsquos LymphomaStaging

bull Stage is the term used to describe the extent of tumor that has spread through the body ( I and II are localized where as III and IV are advanced

bull Each stage is then divided into categories A B and Endash A No systemic symptomsndash B Systemic Symptoms such as fever night

sweats and weight lossndash E Spreading of disease from lymph node to

another organ

Stage I Stage II Stage III Stage IV

Staging of lymphoma

A absence of B symptomsB fever night sweats weight loss

Staging

Symptoms

bull Painful Swelling of lymph nodes located in the neck underarm and groin

bull Unexplained Fever

bull Night Sweats

Diagnosis requires an adequate biopsy

bull Diagnosis should be biopsy-proven before treatment is initiated

bull Need enough tissue to assess cells and architecturendash open bx vs core needle bx vs FNA

Treatment

bull Non-Hodgkinrsquos Lymphoma is usually treated by a team of physicians including hematologists medical oncologists and a radiation oncologist

bull In some cases such as for Indolent lymphomas the Doctor may wait to start treatment until the patient starts showing symptoms known as ldquowatchful waitingrdquo

Treatment Options

Diagnosis requires an adequate biopsy

bull Diagnosis should be biopsy-proven before treatment is initiated

bull Need enough tissue to assess cells and architecturendash open bx vs core needle bx vs FNA

Treatment
