B-cell lymphoma is a cancer that starts in B lymphocytes, which are white blood cells that normally make antibodies to help you fight germs. In lymphoma, some B cells develop DNA changes that make them grow too fast and live too long. These cells collect in lymph nodes (small glands in the neck, armpits, chest, belly, and groin), the spleen, bone marrow, and sometimes in organs such as the stomach, skin, brain, or lungs. Lymph nodes can swell and form painless lumps. Some B-cell lymphomas grow slowly (indolent). Others grow quickly (aggressive). Doctors diagnose the exact type by removing a lymph node or tissue sample and studying the cells under a microscope with special stains and genetic tests. Treatment and outlook depend on the subtype, stage, and how fast it grows. National Cancer Institute+1
B-cell lymphoma is a cancer that starts in B lymphocytes, the white blood cells that normally make antibodies to fight germs. In this disease, one B cell picks up DNA changes and begins to grow out of control. The abnormal cells crowd out healthy immune cells and can form firm, painless lumps in lymph nodes or organs (like spleen, liver, bone marrow). Doctors group B-cell lymphomas into “aggressive/fast-growing” (for example, diffuse large B-cell lymphoma) and “indolent/slow-growing” (for example, follicular lymphoma). The exact plan of care depends on the type, stage, age, and other health issues. (Evidence: WHO/ICC lymphoma classifications; NCCN/ESMO guidelines on B-cell lymphomas.)
Other names
People and websites often use several names for the same group of diseases:
Non-Hodgkin lymphoma (NHL) – a large umbrella term that includes most B-cell lymphomas and some T-cell lymphomas. Many resources will say “B-cell NHL.” American Cancer Society
Mature B-cell neoplasms – the classification term used by the World Health Organization (WHO) and the International Consensus Classification (ICC). It means cancers of B cells that have developed beyond the early “immature” stage. Nature+1
Specific subtype names such as “diffuse large B-cell lymphoma,” “follicular lymphoma,” or “mantle cell lymphoma.” These subtypes behave differently and are treated differently. NCCN+1
Types
Doctors group B-cell lymphomas by how the cells look, what markers they carry, and what genetic changes they have. The lists below reflect modern WHO/ICC systems (you may see small naming differences between systems). PubMed+3Nature+3ASH Publications+3
Diffuse large B-cell lymphoma (DLBCL). The most common fast-growing B-cell lymphoma in adults. It usually presents with rapidly enlarging nodes, often with fever, night sweats, or weight loss. Many cases are very treatable with combination therapy. NCCN
High-grade B-cell lymphoma (HGBL). A very fast-growing group that can have “double-hit” or “triple-hit” gene rearrangements (for example involving MYC, BCL2, and/or BCL6). These genetics help doctors choose therapy intensity. ASH Publications
Primary mediastinal (thymic) large B-cell lymphoma. A subtype that typically affects young adults, often women, presenting as a chest mass behind the breastbone. JNCCN
Burkitt lymphoma. One of the fastest-growing human tumors, often linked to EBV in endemic regions. It needs urgent, intensive treatment but can be curable. National Cancer Institute
Follicular lymphoma. A common slow-growing (indolent) lymphoma arising from germinal-center B cells. People may live many years; treatment timing depends on symptoms and tumor burden. NCCN
Marginal zone lymphomas (MZL). Indolent lymphomas that start in marginal-zone B cells. They include extranodal MALT lymphoma (often in the stomach or eye region), nodal MZL, and splenic MZL. Some cases are linked to chronic infections such as Helicobacter pylori. Nature
Mantle cell lymphoma (MCL). Usually an aggressive lymphoma with a characteristic CCND1 (cyclin D1) gene change; it can sometimes behave more slowly. ASH Publications
Chronic lymphocytic leukemia / small lymphocytic lymphoma (CLL/SLL). The same disease seen in blood (CLL) and nodes (SLL). It is usually slow-growing but can transform. Nature
Lymphoplasmacytic lymphoma (including Waldenström macroglobulinemia). Produces an IgM protein that can thicken the blood and cause vision and nerve problems. Often carries the MYD88 L265P mutation. Nature
Hairy cell leukemia (HCL). A rare B-cell leukemia that often presents with fatigue, infections, and an enlarged spleen; the cells look “hairy” under the microscope. Nature
Primary CNS lymphoma (PCNSL). A DLBCL that starts in the brain, spinal cord, or eye. It causes neurologic symptoms and is treated differently from nodal disease. Annals of Oncology
Plasmablastic lymphoma and other EBV-positive B-cell lymphomas. Often occur in people with weakened immune systems and can be aggressive. ASH Publications
Note: Different guideline sets sometimes group or rename entities. Your pathology report will state the exact subtype used by that lab.
Causes and risk factors
“Cause” in cancer usually means a factor that raises risk; most patients have no single known cause. The items below summarize well-supported risk factors. American Cancer Society+1
Older age. Risk rises as people get older because more DNA damage builds up in cells over time. American Cancer Society
Male sex. Males have a slightly higher risk for many NHL subtypes for reasons that are not fully understood. American Cancer Society
Family history of lymphoma. Having a close relative with lymphoma modestly increases risk, suggesting shared genes or environments. American Cancer Society
Weakened immune system (immunosuppression). HIV infection, medicines after organ transplant, or congenital immune disorders allow abnormal B cells to grow unchecked. American Cancer Society
Autoimmune diseases. Conditions like rheumatoid arthritis, Sjögren syndrome, and celiac disease cause chronic immune stimulation that can trigger B-cell changes. American Cancer Society
Epstein–Barr virus (EBV). EBV can drive certain aggressive B-cell lymphomas, especially in immunosuppressed people. Nature
Helicobacter pylori infection. Long-standing stomach infection can cause MALT lymphoma; treating the infection can sometimes shrink the lymphoma. Nature
Hepatitis C virus (HCV). Linked to marginal zone and some diffuse large B-cell lymphomas; antiviral therapy can help in selected cases. Nature
Hepatitis B virus (HBV). Associated with increased NHL risk and important to identify before therapy because some drugs can reactivate HBV. American Cancer Society
Human herpesvirus-8 (HHV-8). Can be associated with certain B-cell proliferations, particularly in immunodeficiency. Nature
Chlamydophila psittaci. Linked to ocular adnexal MALT lymphoma in some geographic regions. Nature
Borrelia burgdorferi. Associated with some skin (cutaneous) MALT lymphomas in areas where Lyme disease is common. Nature
Campylobacter jejuni. Associated with immunoproliferative small intestinal disease (a form of MALT lymphoma). Nature
Pesticide and solvent exposure (e.g., benzene). Some studies suggest a higher NHL risk with certain chemical exposures. American Cancer Society
Prior radiation exposure. High-dose radiation can increase NHL risk years later. American Cancer Society
Obesity. Higher body weight is linked with increased NHL risk and can affect outcomes. American Cancer Society
Ethnicity and geography. Rates vary across regions and ethnic groups, reflecting environment and genetics. American Cancer Society
Certain medicines that suppress immunity. Post-transplant drugs and long-term strong immune-suppressing medicines increase risk. American Cancer Society
Chronic antigen stimulation. Long-lasting infections or autoimmune activity keep B cells dividing and slightly raise the chance of malignant change. (This is a unifying mechanism behind several risks above.) Nature
No identifiable risk. Many people with B-cell lymphoma have no known risk factor; random DNA errors during cell division likely play a role. American Cancer Society
Symptoms
Symptoms depend on where lymphoma cells collect and how fast they grow. Not everyone has all of these. See a doctor if symptoms last more than a couple of weeks. National Cancer Institute+1
Painless swollen lymph nodes. You might feel rubbery lumps in the neck, underarm, or groin. They usually are not tender. American Cancer Society
Fever. Unexplained fevers, sometimes coming and going, can reflect immune chemicals released by lymphoma cells. National Cancer Institute
Drenching night sweats. Waking up soaked can be a lymphoma “B symptom.” National Cancer Institute
Unplanned weight loss. Losing more than 10% of body weight over 6 months without trying is another “B symptom.” American Cancer Society
Fatigue and weakness. Tiredness can come from inflammation, anemia, or poor sleep due to night sweats. National Cancer Institute
Fullness or swelling of the belly. Enlarged spleen or abdominal nodes can cause bloating or early fullness when eating. American Cancer Society
Chest pressure, cough, or shortness of breath. A mass in the chest can press on nearby structures. American Cancer Society
Itching or skin rashes. Immune chemicals or skin involvement can cause itch. (More typical in some lymphomas than others.) American Cancer Society
Frequent or severe infections. Abnormal B cells make fewer effective antibodies, weakening infection defense. American Cancer Society
Easy bruising or bleeding. If the bone marrow is involved, platelet counts can fall. American Cancer Society
Bone pain. Bone marrow disease or cytokines may cause aching. American Cancer Society
Nerve problems. Numbness, tingling, or weakness can occur if nerves are compressed or—in rare cases—directly involved (neurolymphomatosis). American Cancer Society
Headache, vision changes, or confusion. Primary CNS lymphoma or high blood “thickness” from IgM (Waldenström) can cause neurologic symptoms. Annals of Oncology
Persistent stomach upset. Stomach MALT lymphoma can present with indigestion, pain, or anemia from slow bleeding. Nature
Swollen face and neck veins (SVC syndrome). A large chest mass can block venous return and cause facial swelling and shortness of breath; this needs urgent care. NCCN
Diagnostic tests
A) Physical exam (what the clinician looks for)
General inspection and vital signs. The doctor checks weight, temperature, pulse, and blood pressure, looking for fever, weight loss, and signs of illness. This simple information helps stage symptoms and urgency. National Cancer Institute
Lymph node mapping. The neck, armpits, above/below the clavicles, and groin are carefully felt to record size, number, and whether nodes are stuck together. This baseline exam helps track change over time. American Cancer Society
Abdominal and spleen exam. The doctor feels and sometimes percusses the belly to detect an enlarged spleen or liver, which can signal spread beyond nodes. American Cancer Society
Skin and mucosa check. Rashes, bruises, mouth ulcers, or pallor may point to bleeding risk, infection risk, or anemia. American Cancer Society
Neurologic screen. Simple checks of strength, sensation, coordination, and eye movements look for CNS or nerve involvement. Annals of Oncology
B) “Manual” bedside tests (hands-on clinical maneuvers/tools)
Performance status scoring (ECOG). A quick assessment of how illness limits daily activity. It guides treatment intensity and prognosis. Annals of Oncology
Spleen percussion and palpation techniques. Bedside maneuvers (like Castell’s sign) help detect spleen enlargement when imaging is not immediately available. These findings guide urgent work-up. American Cancer Society
Airway and SVC compression checks. Bedside evaluation for stridor, facial swelling, or neck-vein distension can identify dangerous chest-mass effects before imaging. NCCN
Simple vision and cranial-nerve tests. For people with headaches, confusion, or visual symptoms, quick in-office tests can triage possible eye/CNS involvement. Annals of Oncology
B-symptom assessment. A structured review of fever, night sweats, and weight loss documents symptoms used in staging and risk scores. National Cancer Institute
Note: Manual/bedside tests support—but do not replace—definitive lab, pathology, and imaging studies.
C) Lab & pathological tests (the core of diagnosis)
Complete blood count (CBC) with differential. Looks for anemia, low platelets, or abnormal lymphocytes, which can suggest marrow involvement or leukemic phase. American Cancer Society
Chemistry panel, kidney and liver tests. Baseline organ function guides imaging contrast use and later therapy choices. Annals of Oncology
LDH and uric acid. Elevated LDH suggests fast-growing disease; uric acid helps detect tumor lysis risk. These markers appear in staging/risk tools. Annals of Oncology
Hepatitis B, Hepatitis C, and HIV tests. Results affect both cause and treatment safety (some therapies can reactivate hepatitis B). American Cancer Society
Excisional lymph node biopsy (gold standard). Removing a whole node provides enough tissue to define the exact subtype. Needle biopsies can help but sometimes miss key features. NCCN
Immunohistochemistry (IHC) and flow cytometry. These tests identify B-cell markers (e.g., CD20, PAX5) and patterns that separate subtypes (e.g., germinal-center vs non-germinal-center DLBCL). Nature
Cytogenetics/FISH. Looks for gene translocations or copy-number changes such as BCL2, BCL6, and MYC; finding “double-hit” or “triple-hit” changes puts disease into a high-grade category. ASH Publications
Molecular tests. Clonality studies of the immunoglobulin heavy-chain gene (IGH), MYD88 L265P testing in Waldenström, or BRAF V600E in hairy cell leukemia help confirm specific entities and tailor therapy. Nature
Bone marrow aspiration and biopsy. Checks whether lymphoma has reached the marrow; results affect stage and treatment planning. NCCN
Serum protein studies. Tests like serum protein electrophoresis (SPEP), immunofixation, and free light chains detect abnormal antibody proteins in lymphoplasmacytic lymphoma and related disorders. Nature
D) Electrodiagnostic tests (limited, situation-specific role)
Electrodiagnostic testing is not central to diagnosing lymphoma, but it can help in special cases.
Electrocardiogram (ECG). If you have chest symptoms or will receive heart-affecting medicines later, an ECG sets a baseline; it does not diagnose lymphoma but supports safe care. Annals of Oncology
Nerve conduction studies and EMG. Used when numbness or weakness suggests nerve compression or rare nerve infiltration by lymphoma. They point to nerve damage patterns that trigger imaging or biopsy. American Cancer Society
Electroencephalogram (EEG). Considered when seizures or altered awareness raise concern for CNS involvement; it shows brain activity changes but does not confirm lymphoma without imaging/biopsy. Annals of Oncology
E) Imaging tests (for mapping disease and staging)
Ultrasound. A quick way to look at superficial nodes or the belly (liver, spleen) without radiation; often used to guide needle biopsies. Annals of Oncology
CT scan (neck/chest/abdomen/pelvis). Shows enlarged nodes and organ involvement throughout the body and is commonly used in staging. NCCN
FDG-PET/CT. Many B-cell lymphomas take up radioactive sugar (FDG), so PET/CT maps active disease and checks treatment response using standardized Deauville criteria. It is central in aggressive subtypes like DLBCL. Annals of Oncology
MRI of brain/spine or area of concern. Needed if symptoms suggest CNS disease (headache, vision changes, nerve deficits) or if the eye/brain is involved. Annals of Oncology
Chest X-ray. A simple first look for a large mediastinal mass or lung effects when chest symptoms are present. More detailed scans follow. NCCN
Imaging defines the stage and guides biopsy targets, but the final diagnosis always requires tissue (biopsy) plus lab/pathology studies. NCCN
Non-Pharmacological Treatments (Therapies and Others)
1) Individual oncology nursing education
A one-on-one teaching session helps you understand your exact lymphoma type, tests, expected side effects, red-flag symptoms, and emergency contacts. Clear instructions reduce anxiety, improve adherence, and lower avoidable ER visits. Bring your medicines, supplements, and questions. Ask for written and digital copies. Repeat teaching before each new phase (chemo, immunotherapy, radiation). Purpose: improve safety and confidence. Mechanism: knowledge replaces uncertainty; better self-care decisions and earlier reporting of problems. (Evidence: ASCO survivorship care models; patient-education trials improving adherence and outcomes.)
2) Infection-prevention routine (neutropenia bundle)
During low-white-cell periods, follow strict hand hygiene, mask use in crowds, safe food handling, and daily temperature checks. Keep a “fever plan” to call if temperature ≥38.0 °C (100.4 °F). Avoid sick contacts and high-risk exposures (freshwater hot tubs, yard work without gloves). Purpose: cut serious infections. Mechanism: lowers pathogen exposure while immune defenses are weak. (Evidence: IDSA neutropenia prevention guidance; NCCN infection risk-reduction.)
3) Vaccination planning (non-live vaccines only)
Get seasonal influenza, updated COVID-19, and indicated pneumococcal vaccines before treatment when possible; avoid live vaccines during and shortly after therapy. Household members should also be up-to-date. Purpose: reduce vaccine-preventable illness. Mechanism: priming immunity ahead of B-cell–depleting therapy; indirect “cocooning” by family shots. (Evidence: CDC/ACIP; ASCO/IDSA vaccination in immunocompromised adults.)
4) Oral care program
Brush gently with a soft brush, floss if platelets allow, and use bland rinses (e.g., salt-bicarbonate). See a dentist prior to therapy to treat active dental infections. Purpose: prevent mouth sores and bloodstream infections. Mechanism: lowers oral bacterial load and trauma. (Evidence: MASCC/ISOO mucositis guidelines.)
5) Energy-conserving, light-to-moderate exercise
Short, frequent walks and light resistance bands 3–5 days/week support strength, mood, and sleep. Adjust by fatigue level and blood counts. Purpose: preserve function and reduce chemo-related fatigue. Mechanism: improves mitochondrial efficiency and counters deconditioning. (Evidence: Cochrane reviews on exercise in cancer; ASCO fatigue guidance.)
6) Sleep hygiene and fatigue pacing
Regular bed/wake times, daytime light, limiting late caffeine, and planned rests prevent “boom-and-bust” exhaustion. Purpose: better daytime energy. Mechanism: stabilizes circadian rhythm and reduces sleep fragmentation. (Evidence: Oncology fatigue management guidelines.)
7) Dietitian-guided nutrition
A registered dietitian can tailor calories and protein, manage weight loss or gain, and advise on safe foods during neutropenia (fully cooked meats/eggs, pasteurized dairy). Purpose: maintain strength and reduce hospitalizations. Mechanism: prevents malnutrition and micronutrient deficits. (Evidence: ESPEN/ASPEN oncology nutrition guidance.)
8) Mindfulness-based stress reduction (MBSR)
Simple breath focus, brief meditations, or body scans lower stress reactivity and improve coping. Purpose: reduce anxiety and insomnia. Mechanism: down-regulates hypothalamic–pituitary–adrenal (HPA) axis and sympathetic arousal. (Evidence: RCTs of MBSR in cancer survivors.)
9) Cognitive-behavioral therapy (CBT) for worry and insomnia
Brief CBT skills—thought reframing, stimulus control, and sleep restriction—can cut rumination and improve sleep quality. Purpose: better mood and function. Mechanism: changes unhelpful thoughts and behaviors that maintain anxiety/insomnia. (Evidence: Clinical trials of CBT-I and CBT for cancer.)
10) Physical therapy and balance training
Targeted plans address neuropathy, joint stiffness, and post-treatment weakness. Purpose: restore mobility and lower fall risk. Mechanism: graded strengthening and proprioceptive drills. (Evidence: Oncology rehab best-practice statements.)
11) Lymphedema risk reduction
If lymph nodes are removed or irradiated, use gentle compression as advised, moisturize skin, avoid cuts, and manage infections early. Purpose: prevent chronic swelling. Mechanism: supports lymph flow and protects skin barrier. (Evidence: International Lymphedema Framework.)
12) Fertility preservation counseling (when relevant)
Before first treatment, review sperm banking or egg/embryo freezing options. Purpose: protect future family plans. Mechanism: preserves gametes before chemo-related gonad damage. (Evidence: ASCO fertility preservation guideline.)
13) Social work and financial counseling
Help with insurance, transport, work letters, and grants reduces treatment breaks. Purpose: keep care on track. Mechanism: removes practical barriers to adherence. (Evidence: Oncology navigation and outcomes research.)
14) Palliative care (early integration)
Palliative care manages symptoms (pain, nausea, breathlessness), clarifies goals, and supports families from diagnosis onward—not only end-of-life. Purpose: better quality of life and sometimes longer survival. Mechanism: proactive symptom control and decision support. (Evidence: Early palliative care trials in oncology.)
15) Non-drug pain strategies (heat/cold, TENS, relaxation)
Simple modalities plus gentle stretching can reduce muscle tension and neuropathic flares. Purpose: fewer opioids and better function. Mechanism: gate control of pain and muscle relaxation. (Evidence: Pain management guidelines.)
16) Acupuncture (where available/appropriate)
May help nausea, hot flashes, and some neuropathic symptoms for selected patients. Purpose: symptom relief. Mechanism: neuromodulation and endorphin release. (Evidence: Systematic reviews of acupuncture in cancer symptoms.)
17) Safe sunlight and vitamin D plan
With clinician approval, modest outdoor light plus tested vitamin D status can support bone and mood, while avoiding sunburn during photosensitizing chemo. Purpose: bone health and wellness. Mechanism: maintains 25-OH-vitamin D within target range. (Evidence: Endocrine Society guidance; survivorship care.)
18) Spiritual care/chaplaincy
Values and meaning-centered visits can reduce distress and guide choices that match personal beliefs. Purpose: emotional resilience. Mechanism: strengthens coping frameworks. (Evidence: Psycho-oncology literature on spiritual well-being.)
19) Advance care planning
Naming a health-care proxy and discussing preferences provides control if sudden illness happens. Purpose: aligned care. Mechanism: documented choices guide teams in emergencies. (Evidence: Oncology consensus on goals-of-care discussions.)
20) Survivorship plan after treatment
A written plan lists your diagnosis, treatments received, late-effect watch-outs, vaccines, and follow-up schedule. Purpose: safer long-term care. Mechanism: structured monitoring reduces missed problems. (Evidence: ASCO survivorship care plans.)
Drug Treatments

(For all drugs above: primary source is FDA Prescribing Information hosted at accessdata.fda.gov; clinicians also follow disease-specific NCCN/ESMO pathways.)
Dietary Molecular Supplements
1) Vitamin D3 (cholecalciferol)
Many people with lymphoma are low in vitamin D. Typical maintenance doses range 800–2000 IU/day; deficiency may need short-term higher repletion. Function: bone, muscle, and immune support. Mechanism: vitamin D receptor signaling modulates innate and adaptive immunity. Avoid mega-doses; check levels to target a safe range. (Evidence: Endocrine Society vitamin D guideline; observational links in lymphoma—no cure claims.)
2) Omega-3 fatty acids (EPA/DHA)
Common dose 1–2 g/day combined EPA/DHA with meals. Function: support triglyceride control and may reduce inflammation. Mechanism: incorporation into cell membranes and eicosanoid balance. Watch for bleeding risk if combined with anticoagulants or BTK inhibitors. (Evidence: AHA science advisory; drug-interaction cautions.)
3) Probiotics (clinician-approved strains only)
Doses vary by product (e.g., 10⁹–10¹⁰ CFU/day). Function: gut comfort and stool regularity. Mechanism: microbiome support. Do not use in severe neutropenia or with central lines without team approval due to rare bloodstream infection risk. (Evidence: IDSA cautions; mixed oncology data.)
4) Curcumin (turmeric extract, standardized)
Often 500–1000 mg/day of curcuminoids with food to enhance absorption. Function: anti-inflammatory adjunct for aches or stiffness. Mechanism: NF-κB and cytokine modulation. May interact with some chemo or targeted drugs; stop before procedures due to bleeding risk. (Evidence: Pharmacology reviews; interaction cautions.)
5) Green tea extract (EGCG)
Low-to-moderate dosing (e.g., 200–400 mg/day EGCG). Function: antioxidant adjunct; not a cancer treatment. Mechanism: polyphenol signaling. Avoid high doses with BTK inhibitors or bortezomib (lab interactions reported). (Evidence: Supplement–drug interaction literature.)
6) Melatonin
Typical 2–5 mg at bedtime. Function: sleep onset aid; may ease jet lag. Mechanism: MT1/MT2 receptor—circadian alignment. Can interact with sedatives; start low and review with clinician. (Evidence: Sleep medicine guidance; small oncology trials.)
7) Selenium (if deficient)
Diet usually supplies enough; targeted supplementation 50–100 mcg/day may be considered if low. Function: antioxidant enzyme cofactor. Mechanism: glutathione peroxidase activity. Excess can cause hair/nail brittleness and GI upset—avoid high doses. (Evidence: Micronutrient guidelines.)
8) Magnesium (as glycinate or citrate)
Typical 200–400 mg elemental/day if low or with muscle cramps. Function: nerve/muscle stability, bowel regularity. Mechanism: cofactor in >300 enzymes. Adjust for kidney function; diarrhea can occur. (Evidence: Electrolyte management guidance.)
9) Ginger root extract
250–500 mg before meals may help nausea in some patients. Function: settle stomach. Mechanism: 5-HT3 and cholinergic effects. Still follow anti-emetic plans prescribed by your team. (Evidence: RCTs in nausea—mixed but generally favorable for mild symptoms.)
10) Quercetin (caution)
Sometimes used at 250–500 mg/day for allergy-type symptoms. Mechanism: mast-cell stabilization/antioxidant. Caution: may affect drug transporters (e.g., P-gp/CYP). Do not start without oncology approval. (Evidence: Pharmacokinetic interaction reports.)
Immunity-Support / Regenerative / Stem-Cell–Related
1) Filgrastim (G-CSF)
Dose: daily subcutaneous injections (weight-based) after chemo. Function: raise neutrophils to lower infection risk and shorten neutropenia. Mechanism: stimulates bone-marrow granulocyte production. (Evidence: FDA label; ASCO neutropenia prophylaxis.)
2) Pegfilgrastim
Dose: single subcutaneous dose once per chemo cycle (long-acting G-CSF). Function/Mechanism: as above with convenience of once-per-cycle dosing. (Evidence: FDA label.)
3) Sargramostim (GM-CSF)
Dose: subcutaneous/IV per protocol. Function: support recovery of neutrophils/monocytes, sometimes post-transplant. Mechanism: stimulates myeloid progenitors. (Evidence: FDA label; transplant protocols.)
4) Plerixafor
Dose: subcutaneous with G-CSF when mobilizing stem cells for autologous transplant. Function: improve collection of CD34+ cells. Mechanism: CXCR4 antagonist releases stem cells into bloodstream. (Evidence: FDA label.)
5) Intravenous immunoglobulin (IVIG)
Dose: weight-based IV dosing at intervals for recurrent infections with proven low IgG. Function: provide pooled antibodies while B cells are depleted. Mechanism: passive immunity. (Evidence: Immunology/hematology guidance; FDA labels.)
6) Palifermin
Dose: IV before/after high-dose chemo with transplant. Function: reduce severe mouth sores. Mechanism: keratinocyte growth factor promotes mucosal healing. (Evidence: FDA label.)
Procedures and Surgeries
1) Excisional lymph-node biopsy
A surgeon removes one whole node to confirm the exact lymphoma type by pathology, immunohistochemistry, and molecular tests. Why: full tissue is the gold standard for diagnosis and guides therapy. (Evidence: Hematopathology standards; NCCN workup.)
2) Bone marrow biopsy/aspiration
A hollow needle samples marrow from the hip to see if lymphoma has spread and to check blood-forming cells. Why: staging and baseline marrow health. (Evidence: Lymphoma staging protocols.)
3) Implanted port (central venous access device)
A small chamber under the skin connects to a central vein for safe IV chemo and blood draws. Why: protects small veins and enables complex regimens. (Evidence: Infusion therapy standards.)
4) Splenectomy (selected cases)
Removal of the spleen may be used for symptomatic splenic marginal zone lymphoma or severe hypersplenism causing low blood counts. Why: relieve symptoms and improve counts when drugs are not enough. (Evidence: Case series and guideline statements.)
5) Autologous or allogeneic hematopoietic stem-cell transplant
Not a “surgery,” but a major inpatient procedure where high-dose chemo is followed by stem-cell rescue (autologous) or donor cells (allogeneic). Why: salvage or curative intent in selected relapsed cases. (Evidence: EBMT/ASTCT guidelines.)
Practical Preventions
Hand hygiene and food safety (cook meats/eggs fully; avoid unpasteurized foods). (Evidence: IDSA neutropenia guidance.)
Vaccines on schedule (non-live; household members vaccinated). (Evidence: ACIP/ASCO.)
Prompt fever plan (call if ≥38.0 °C). (Evidence: IDSA.)
Oral and skin care to reduce portals of infection. (Evidence: MASCC/ISOO.)
Medication adherence using pill boxes and reminders. (Evidence: Adherence research.)
Avoid high-risk exposures (crowded indoor spaces during nadir, gardening without gloves). (Evidence: IDSA.)
Sun protection if receiving photosensitizing drugs. (Evidence: Dermatology/oncology cautions.)
Safe sex practices and HBV/HCV screening as directed. (Evidence: Hepatitis reactivation guidance.)
Regular light exercise and fall prevention at home. (Evidence: Oncology rehab.)
Keep follow-up appointments and labs—early fixes prevent big problems. (Evidence: Survivorship care.)
When to See a Doctor Urgently
Call your oncology team or go to emergency care now for fever ≥38.0 °C, shaking chills, shortness of breath, chest pain, uncontrolled vomiting/diarrhea, bleeding that won’t stop, severe headache or confusion, new one-sided weakness, painful leg swelling, or if you simply feel “very unwell.” These can signal infection, blood clots, dehydration, or treatment complications that cannot wait. (Evidence: IDSA febrile neutropenia; oncology emergency triage protocols.)
What to Eat and What to Avoid
Eat:
Small, frequent protein-rich meals (eggs, fish, beans) to maintain strength. (Evidence: Oncology nutrition guidance.)
Cooked vegetables and peeled fruits to lower microbe load during neutropenia. (Evidence: Food safety guidance.)
Whole grains for steady energy and bowel regularity. (Evidence: Nutrition guidelines.)
Fermented pasteurized yogurt/kefir if your team approves. (Evidence: Food safety.)
Fluids—water, broths, oral rehydration—target pale-yellow urine. (Evidence: Dehydration prevention.)
Avoid or Limit:
- Raw or undercooked meats, fish (sushi), runny eggs, unpasteurized juices/dairy. (Evidence: IDSA/food safety.)
- Grapefruit or Seville orange with certain drugs (can change levels of BTK inhibitors and others). (Evidence: Drug–food interaction labeling.)
- Herbal products with strong interactions (St. John’s wort, high-dose green tea extracts) unless cleared by your team. (Evidence: Pharmacology interactions.)
- Heavy alcohol—worsens dehydration and interacts with many meds. (Evidence: Hepatology guidance.)
- Mega-dose antioxidants during active chemo/immunotherapy unless your clinician says otherwise. (Evidence: Mixed data; oncology caution statements.)
Frequently Asked Questions
1) Is B-cell lymphoma curable?
Many aggressive types (like DLBCL) are often curable with standard regimens; indolent types can be controlled for many years with intermittent therapy. Outcome varies by subtype, stage, and patient health. (Evidence: NCCN outcomes by subtype.)
2) Do all B-cell lymphomas need immediate treatment?
No. Some slow types can be safely monitored (“watchful waiting”) until clear signs show benefit from therapy. (Evidence: Trials in follicular lymphoma.)
3) Will I lose my hair?
Some regimens (e.g., R-CHOP) commonly cause hair loss; others may not. Hair usually regrows after treatment ends. (Evidence: Chemo side-effect profiles.)
4) Can I keep working?
Many people work part-time or full-time with adjustments. Plan around infusion days and low-count weeks; ask for workplace accommodations. (Evidence: Survivorship and work studies.)
5) What about pregnancy and fertility?
Discuss fertility preservation before treatment. Some drugs can harm fertility or a fetus; reliable contraception is essential during therapy. (Evidence: ASCO fertility guideline.)
6) Are complementary therapies safe?
Some can help symptoms (e.g., acupuncture for nausea). But herbs/supplements can interact with anti-cancer drugs. Always clear them with your team. (Evidence: Interaction reports; ASCO integrative oncology guidance.)
7) How are side effects managed?
Teams use anti-nausea drugs, growth factors, dose adjustments, and supportive care. Report problems early for fast fixes. (Evidence: MASCC/ASCO supportive care.)
8) What tests will I have?
Typically PET/CT or CT scans, blood tests, sometimes bone marrow biopsy, and response scans after a few cycles. (Evidence: Response assessment criteria like Lugano.)
9) What is “maintenance therapy”?
In some indolent types, scheduled antibodies after induction can prolong remission. Not needed for every subtype. (Evidence: Trials in FL maintenance.)
10) Can vaccines work after anti-CD20 therapy?
Response may be weaker for months after B-cell-depleting drugs. Time shots when your team advises. (Evidence: Vaccine response studies in anti-CD20 recipients.)
11) Is CAR-T a last resort?
CAR-T is for specific relapsed/refractory settings and sometimes used earlier in high-risk disease, depending on guidelines and approvals. (Evidence: CAR-T trials and labels.)
12) How long will treatment last?
From a single infusion (CAR-T) to several months of cycles; some oral drugs continue until progression or intolerance. Your plan will specify length. (Evidence: Regimen protocols.)
13) What is tumor lysis syndrome?
A rapid release of cell contents when many cancer cells die at once—can affect kidneys and heart. Teams prevent it with hydration and monitoring, especially with drugs like venetoclax. (Evidence: TLS prevention guidelines.)
14) Can I travel?
Often yes, with planning—carry meds, know where to get urgent care, avoid travel during nadir, and get clinician clearance. (Evidence: Oncology travel advice.)
15) What does remission mean?
No signs of active disease on exams and scans; some microscopic cells may remain. Regular follow-ups monitor for return. (Evidence: Response criteria and survivorship plans.)
