B-cell prolymphocytic leukemia is a rare, aggressive leukemia that arises from mature B-lymphocytes (a type of white blood cell). Under the microscope, the blood and bone marrow show a high number of larger-than-normal lymphocytes called prolymphocytes with prominent central nucleoli. Clinically, people often present with very high white-cell counts, rapid spleen enlargement, fatigue, night sweats, weight loss, and sometimes swollen lymph nodes. Genetically, many cases harbor high-risk abnormalities such as TP53 disruption (deletions/mutations). Important update: in the 2022/2024 WHO 5th edition of hematolymphoid tumor classification, “B-PLL” as a stand-alone diagnostic category was deleted because cases are heterogeneous; most are now classified as splenic B-cell lymphoma/leukemia with prominent nucleoli (SBLPN) or as transformation of another indolent B-cell lymphoma (or occasionally mantle cell lymphoma). Clinically, people who were labeled “B-PLL” are still treated using modern CLL-like strategies (BTK inhibitors, venetoclax ± anti-CD20, chemo-immunotherapy, and stem-cell transplant in select fit patients). PubMed+3NCBI+3Pathology Society Journals+3
B-cell prolymphocytic leukemia (B-PLL) is a rare blood cancer of mature B-cells. It shows very high counts of abnormal white cells in the blood. Most of these circulating cells are prolymphocytes, which are larger lymphocytes with a single, big nucleolus (a round spot inside the nucleus). Doctors diagnose B-PLL when more than 55% of the blood lymphocytes are prolymphocytes, and when other look-alike diseases are ruled out. People often have a very large spleen. The disease tends to be fast-growing. SEER+2PMC+2
Naming changed recently. The WHO 5th edition (2022) moved many cases that used to be called “B-PLL” into a new splenic disease group called “splenic B-cell lymphoma/leukemia with prominent nucleoli (SBLPN),” especially the cases that lack CD5 and resemble “hairy cell leukemia variant.” The International Consensus Classification (ICC 2022) still keeps de novo B-PLL as a diagnosis, but only when other diseases (like CLL in prolymphocytic progression, mantle cell lymphoma, or SBLPN) are clearly excluded. This is why you may see different names in reports. Modern Pathology+3Nature+3PMC+3
Other names
B-cell prolymphocytic leukemia; B-prolymphocytic leukemia; B-PLL; B-cell PLL; “prolymphocytic leukemia, B-cell type.” Some older papers used “CD5-negative B-PLL” for subsets; newer papers may label similar CD5-negative splenic cases as SBLPN. Modern Pathology
Types
1) De novo B-PLL. This is a “stand-alone” leukemia that starts as B-PLL, with >55% prolymphocytes, after ruling out other lymphomas. The ICC 2022 keeps this category. BioMed Central
2) Prolymphocytic progression (transformation) from another lymphoma. Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) can progress into a phase with many prolymphocytes; WHO-5 calls that “prolymphocytic progression of CLL.” Rarely, splenic marginal zone lymphoma can also evolve this way. These are not de novo B-PLL. Nature+1
3) Phenotypic subtypes you may read about. Some cases express CD5 (a surface marker), others do not. Many have bright CD20, FMC7, and strong surface immunoglobulin, with CD23 often negative. These features help separate B-PLL from CLL, mantle cell lymphoma, and hairy cell disorders. PMC+1
4) Genetic-risk groupings (used in research). Studies split patients by key changes: MYC activation and TP53 loss (deletion/mutation). The combination of MYC aberration plus del(17p)/TP53 predicts the poorest outcomes. ASH Publications+1
Causes
Note: For most people, there is no single known external cause of de novo B-PLL. Scientists describe internal genetic drivers (changes inside cells) and general leukemia risk factors. When I list environmental items, evidence is for leukemia in general, not specifically proven for B-PLL.
Ageing of the immune system. B-PLL happens mostly in older adults. Age brings DNA damage in lymphocytes, which can help cancer start. SEER
MYC gene activation. The MYC gene controls cell growth. Many B-PLL cases have MYC translocations or gains, which push cells to grow too fast. ASH Publications
TP53 loss or mutation. TP53 is the “guardian” of the genome. When it is deleted or mutated (often with chromosome 17p loss), abnormal cells survive and multiply. lesentreprisescontrelecancer.fr
Complex karyotype. Many B-PLL cells show many chromosome changes at once. This instability speeds cancer behavior. PMC
Prolymphocytic progression of CLL. Some patients with CLL evolve to a phase rich in prolymphocytes; this is a different biology than de novo B-PLL but explains “B-PLL-like” pictures. Nature
Evolution from splenic marginal zone lymphoma (rare). Some splenic lymphomas can undergo prolymphocytoid change that mimics B-PLL. BioMed Central
Other recurrent gene changes. Mutations may occur in MYD88, BCOR, SF3B1, SETD2, CHD2, CXCR4, BCLAF1. They disturb cell signaling, DNA repair, or RNA splicing, aiding growth. atlasgeneticsoncology.org
IGHV gene usage patterns. Many cases use IGHV3 or IGHV4 subgroups; IG genes are clonally rearranged. This shows a single expanded B-cell clone. SEER
Chromosome 13q deletion, trisomy 12, trisomy 3, trisomy 18, del8p. These are reported in cohorts and reflect the unstable genome in B-PLL. lesentreprisescontrelecancer.fr
Immune signaling pathway over-activation. B-cell receptor pathways can stay “on,” promoting survival. (Supported by targeted drug responses seen in lab studies.) PubMed
Benzene exposure (general leukemia risk). Benzene is a proven human leukemogen, especially for AML; it likely raises overall leukemia risk. Not specific to B-PLL. publications.iarc.who.int+1
Ionizing radiation (general leukemia risk). Long-term radiation exposure is linked with leukemia risk overall. Not specific to B-PLL. ScienceDirect+1
Pesticides (general hematologic cancer risk). Multiple studies and reviews link pesticide exposure with leukemia and lymphoma risk. Not specific to B-PLL. PMC+1
Chronic antigen stimulation (hypothesis). Ongoing immune stimulation might select aggressive clones. This is suggested from patterns seen in other B-cell cancers. (Research-based concept.) Nature
Prior chemotherapy or radiotherapy (general risk). Past cancer treatments can rarely lead to secondary leukemias due to DNA damage. (General oncology knowledge; not B-PLL-specific.)
Host DNA repair capacity. Inherited or acquired limits in repairing DNA damage may raise risk of clonal outgrowth in B-cells. (General mechanism; reflected by frequent TP53 changes.) lesentreprisescontrelecancer.fr
Epigenetic dysregulation. Changes in how DNA is packaged (e.g., SETD2) can switch key genes on/off, pushing growth. atlasgeneticsoncology.org
Splicing factor mutations. SF3B1 changes alter RNA processing and can drive malignant behavior. atlasgeneticsoncology.org
Chemokine signaling imbalance. CXCR4 mutations can increase survival signals and tissue homing. atlasgeneticsoncology.org
Combination of MYC + TP53. Having both drives very aggressive disease biology and poor outcomes—functioning as a powerful “cause” of fast growth inside cells. lesentreprisescontrelecancer.fr
Symptoms
Tiredness and low energy. From anemia (low red cells). Haematologica
Shortness of breath on exertion. Also from anemia. Haematologica
Pale skin or gums. A common anemia sign. Haematologica
Fevers without infection. A “B-symptom” driven by the cancer itself. bloodcancerunited.org
Night sweats. Another B-symptom. bloodcancerunited.org
Unintentional weight loss. The third classic B-symptom. Haematologica
Fullness or pain under the left ribs. Due to an enlarged spleen. You may feel full after small meals. Haematologica
Frequent infections. Low or poorly working normal white cells can reduce immune defense. Haematologica
Easy bruising. Platelets can be low. Haematologica
Bleeding from gums or nose. Also from low platelets. Haematologica
Swollen lymph nodes. Some patients have nodes, but often less than in CLL. Haematologica
Recurrent mouth sores or slow healing. From low neutrophils or immune weakness. Haematologica
Bone or back discomfort. Marrow over-activity can cause aches (nonspecific).
Dizziness or faintness. From anemia or low blood pressure when standing.
Itching or skin infections. Immune changes can affect skin defenses.
Diagnostic tests
A) Physical examination (bedside checks)
Vital signs. Fever, fast heart rate, or low blood pressure can suggest infection, anemia, or sepsis risk.
Skin and mucosa check. Look for pallor, bruises, small red dots (petechiae), mouth ulcers—clues to anemia, low platelets, or infection.
Spleen palpation. Doctors feel for an enlarged spleen under the left ribs. Massive splenomegaly is common in B-PLL. Haematologica
Liver size and tenderness. The liver can also enlarge; this helps with staging and symptom planning.
Lymph node survey. Neck, armpit, groin nodes are checked. Nodes can be present, but often are not very large compared with CLL. Haematologica
B) Manual bedside maneuvers (simple “hands-on” tests)
Castell’s spleen percussion. Gentle tapping over the lowest left rib while breathing in can detect spleen enlargement.
Traube’s space percussion. Another tapping method under the left chest to suggest splenomegaly.
Abdominal palpation after meals. Feeling for early fullness and pain helps relate symptoms to spleen size.
Orthostatic blood pressure. Checks for dizziness with standing; anemia or dehydration may contribute.
Manual lymph-node mapping. Systematic palpation to document the size and number of nodes for follow-up comparison.
C) Laboratory and pathological tests (the core of diagnosis)
Complete blood count (CBC) with differential. Shows high lymphocyte count and confirms anemia or low platelets. Prolymphocytes are counted; >55% supports B-PLL. SEER
Peripheral blood smear (microscopy). Under the microscope, prolymphocytes look larger with a single, prominent nucleolus. This is the hallmark cell. PMC
Flow cytometry immunophenotyping. B-PLL usually shows bright CD20, CD19, FMC7, and strong surface immunoglobulin. CD5 is variable; CD23 often negative. This pattern helps separate it from CLL and mantle cell lymphoma. PMC
Rule-out markers. Tests often show cyclin D1 and SOX11 negative (argues against mantle cell), and CD25/CD103 negative (argues against classic hairy cell leukemia). WebPathology
Bone marrow aspiration/biopsy. Confirms marrow involvement and provides material for genetics. SEER
Cytogenetics (karyotype). Looks for many chromosome changes (complex karyotype), common in B-PLL. PMC
FISH for key lesions. MYC rearrangements and 17p deletion (TP53) are frequent and carry prognostic weight. ASH Publications
TP53 sequencing. Finds mutations in the remaining TP53 allele, which often coexist with 17p loss. Frontiers
Immunoglobulin gene studies (IGHV usage/mutation). Many B-PLL cases use IGHV3/IGHV4; IG genes are clonally rearranged. SEER
Chemistry and tumor burden markers. LDH and β2-microglobulin can be high and help track disease activity. (General hematology practice.)
D) Electrodiagnostic tests (supportive, not for the main diagnosis)
12-lead ECG. Baseline heart rhythm check is useful before and during therapies that can affect the heart or blood pressure; also helpful when anemia is severe.
Ambulatory ECG (Holter) if needed. Monitors irregular rhythms if symptoms suggest them.
Pulse oximetry during illness. Quick check for oxygen levels if infection is suspected.
E) Imaging tests (to document organs and rule out other problems)
Abdominal ultrasound. Simple, fast way to measure spleen and liver size and follow them over time.
CT scan of neck/chest/abdomen/pelvis. Maps lymph nodes and organ sizes; helps exclude other lymphoma types. Haematologica
PET/CT (selected cases). Used if doctors suspect transformation or want to evaluate highly active nodes.
Chest X-ray if infection is suspected. Looks for pneumonia when fevers occur.
MRI (selected cases). Rarely needed; can clarify organ findings when CT/US are unclear.
Non-pharmacological treatments (therapies and other supports)
Below are 10 high-value, evidence-based non-drug strategies you can start discussing with a clinician. (I prioritized the options with the strongest data for people on leukemia-type therapies; in practice these sit alongside prescription treatments.)
1) Infection risk reduction & neutropenia precautions
Hand hygiene is the single most important step; clean central-line sites; brush teeth gently; report fevers immediately; avoid sick contacts; and follow shot schedules recommended by your oncology team (e.g., inactivated vaccines). Hospital and outpatient clinics also use standard precautions. These steps meaningfully lower serious infection risk during and after therapy. Cancer.gov+1
2) Safe-food practices (“neutropenic diet” principles)
Emphasize food safety rather than extreme restriction: cook meats/eggs thoroughly; avoid raw sprouts; wash produce well; reheat deli meats until steaming; prevent cross-contamination in the kitchen; refrigerate leftovers promptly. These measures reduce food-borne infections when immunity is low. CDC+2CDC+2
3) Exercise for strength, fatigue, and mood
Regular, moderate aerobic activity (e.g., brisk walking 3×/week) plus light resistance training improves cancer-related fatigue, anxiety, and overall function during and after treatment. Programs are individualized for blood counts and symptoms. PMC+1
4) Nutrition during treatment
Aim for small, frequent, nutrient-dense meals (adequate protein and calories), manage taste changes, and use oral nutrition supplements if needed. A registered dietitian can tailor plans to weight loss, nausea, or mouth sores. American Cancer Society+1
5) Mouth care
Gentle, regular oral hygiene (soft toothbrush, bland rinses) lowers mucositis and infection risk, especially with cytopenias or anti-CD20 therapy. Report oral sores early. Cancer.gov
6) Skin and catheter care
Keep catheter sites clean/dry; protect skin from cuts; moisturize; and use sun protection (some drugs increase photosensitivity). These reduce entry points for bacteria. CDC
7) Sleep, stress, and mental health support
Cognitive-behavioral strategies, relaxation breathing, and counseling can reduce insomnia, distress, and treatment-related anxiety; pair with movement where possible. PMC
8) Vaccination planning
Discuss timing of inactivated vaccines (e.g., influenza) around therapy; live vaccines are generally avoided in immunocompromised states. Your oncology team personalizes the schedule. CDC
9) Fall-prevention & energy conservation
With anemia or neuropathy, use home safety checks, assistive devices as needed, and plan activities during your “best-energy” window to avoid injury. American Cancer Society
10) Early fever action plan
Keep a thermometer at home; if temperature ≥38.0 °C (100.4 °F), call your team or go to emergency care immediately—rapid antibiotics save lives in neutropenia. Cancer.gov
Drug treatments
Because “B-PLL” is now folded into entities managed like high-risk CLL/SBLPN, clinicians commonly use BTK inhibitors, BCL-2 inhibitor (venetoclax) with or without anti-CD20 antibodies, traditional chemo-immunotherapy, and cellular therapy/transplant in selected cases. Below are 12 core agents commonly used, each summarized from its FDA label (dosing abbreviated; labels contain full instructions and warnings). Discuss choices with an oncologist—drug selection depends on genetics (e.g., TP53), fitness, and prior therapies.
1) Ibrutinib (IMBRUVICA®) — BTK inhibitor
Dose/How: 420 mg orally once daily for CLL/SLL until progression/toxicity. Why: Blocks BTK signaling that drives B-cell growth and survival. Use in B-PLL/SBLPN: Case reports/series show activity, especially with TP53 lesions; often used first-line in high-risk biology. Key risks: Atrial fibrillation, bleeding, infections, hypertension, diarrhea; hold around procedures; manage drug–drug interactions. FDA Access Data+2FDA Access Data+2
2) Acalabrutinib (CALQUENCE®) — BTK inhibitor
Dose: 100 mg orally every 12 hours (± obinutuzumab in some regimens). Why: More selective BTK blockade; used similar to ibrutinib in CLL/SLL. Key risks: Headache, cytopenias, infection; adjust with CYP3A interactions. FDA Access Data+2FDA Access Data+2
3) Zanubrutinib (BRUKINSA®) — BTK inhibitor
Dose: 160 mg twice daily or 320 mg once daily for CLL/SLL. Why: Potent BTK occupancy; ALPINE data in CLL favored PFS vs ibrutinib. Key risks: Cytopenias, bleeding, infections; monitor hepatic/renal considerations per label. FDA Access Data+2FDA Access Data+2
4) Pirtobrutinib (JAYPIRCA®) — non-covalent BTK inhibitor
Dose: Per label for CLL/SLL after at least two prior therapies including BTK and BCL-2 inhibitors. Why: Designed to overcome resistance to covalent BTK inhibitors. Key risks: Cytopenias, infections; see hepatic/renal guidance. FDA Access Data+1
5) Venetoclax (VENCLEXTA®) — BCL-2 inhibitor
Dose: 5-week ramp-up (20→50→100→200→400 mg daily) to lower risk of tumor lysis syndrome (TLS); then 400 mg daily (often with rituximab or obinutuzumab per protocol). Why: Triggers apoptosis in B-cells by inhibiting BCL-2. Key risks: TLS (requires strict prophylaxis/monitoring), cytopenias, infections. FDA Access Data+2FDA Access Data+2
6) Rituximab (RITUXAN®) — anti-CD20 monoclonal antibody
Dose: Multiple CLL schedules; infusion reactions require premedication and close monitoring. Why: Depletes CD20+ B-cells; often combined with venetoclax or chemotherapy. Key risks: Infusion reactions, HBV reactivation, PML. FDA Access Data
7) Obinutuzumab (GAZYVA®) — type II anti-CD20 antibody
Dose: For CLL: Cycle 1 split-dose (100 mg Day 1, 900 mg Day 2), then 1,000 mg Day 8 & 15; Cycles 2–6 Day 1 1,000 mg; commonly combined with chlorambucil or venetoclax in CLL-type protocols. Key risks: Infusion reactions, infections, TLS. FDA Access Data+1
8) Bendamustine (TREANDA®) — alkylating agent
Dose: CLL regimen 100 mg/m² IV Days 1–2 every 28 days × up to 6 cycles. Why: Cytotoxic backbone for chemo-immunotherapy (e.g., BR). Key risks: Myelosuppression, infections; dose modify for toxicities. FDA Access Data+1
9) Fludarabine (FLUDARA®/Fludarabine phosphate) — purine analog
Dose: Various CLL regimens and in combinations (e.g., FCR); profound lymphodepletion. Key risks: Myelosuppression, infections, TLS, neurotoxicity; contraception needed. FDA Access Data+1
10) Chlorambucil (LEUKERAN®) — alkylating agent
Dose: Classic oral agent used with obinutuzumab in some CLL settings; exact dose individualized. Key risks: Bone-marrow suppression; careful monitoring needed. FDA Access Data+1
11) Cyclophosphamide — alkylating agent
Dose: Numerous IV schedules; hydration to protect the bladder; part of combination regimens or conditioning for transplant. Key risks: Cytopenias, hemorrhagic cystitis. FDA Access Data+1
12) Alemtuzumab (CAMPATH®) — anti-CD52 monoclonal antibody
Use: Historically for fludarabine-refractory B-CLL; intensive infection prophylaxis/monitoring required. While oncology marketing has changed, the historical label details dosing and safety. Key risks: Profound immunosuppression, CMV reactivation. FDA Access Data+1
Notes from clinical literature: Modern case series support BTK inhibitors and bendamustine-rituximab in B-PLL-phenotype disease, especially with TP53 lesions; therapy mirrors high-risk CLL choices. Decisions are individualized. PubMed+2PMC+2
Dietary molecular supplements
Important: Supplements can interact with leukemia drugs (especially BTK/BCL-2 inhibitors) and are not a substitute for prescription therapy. The strongest evidence in cancer care favors whole-food nutrition and safety rather than single molecules. American Cancer Society+1
High-protein oral nutrition shakes to meet calorie/protein goals when appetite is low; pick pasteurized products; avoid unpasteurized preparations during neutropenia. American Cancer Society
Vitamin D to correct deficiency (lab-guided dosing) supports bone/immune health; avoid megadoses without testing. American Cancer Society
Omega-3 fatty acids (fish oil) may help with weight loss/inflammation; discuss bleeding risk if on BTK inhibitors. American Cancer Society
Probiotics: avoid during significant immunosuppression due to rare bacteremia/fungemia risk. Food-safety first. CDC
Glutamine (for mucositis): mixed evidence; confirm safety with team. American Cancer Society
Plant-based phytonutrients from whole foods (berries, crucifers, beans) are preferred over capsules. Leukemia Research Foundation
Electrolyte solutions for dehydration during diarrhea; choose pasteurized/boiled water sources. American Cancer Society
Multivitamin at standard dietary allowance if intake is poor; avoid high-dose antioxidants around chemo unless your oncologist approves. American Cancer Society
Immune-support/regenerative or stem-cell–related drugs
These are prescription products used by clinicians to manage low counts or as cellular therapy; they are not over-the-counter “boosters.”
Filgrastim (G-CSF; NEUPOGEN®) — stimulates neutrophil recovery and reduces febrile-neutropenia risk during myelosuppressive therapy; dosing is individualized; watch for bone pain and rare splenic rupture. FDA Access Data+1
Pegfilgrastim (NEULASTA®/biosimilars) — long-acting G-CSF dosed once per chemo cycle to lower infection risk; similar cautions as filgrastim. FDA Access Data+1
Eltrombopag (PROMACTA®) — thrombopoietin-receptor agonist used in severe aplastic anemia to raise platelets under specialist care; monitor liver tests and interactions (chelation with cations). FDA Access Data+1
Lisocabtagene maraleucel (BREYANZI®; CAR-T cell therapy) — for adults with relapsed/refractory CLL/SLL after BTK and BCL-2 inhibitors (accelerated approval). Requires REMS-certified centers; risks include cytokine-release syndrome and neurotoxicity. U.S. Food and Drug Administration+1
Procedures / surgeries
Allogeneic hematopoietic stem-cell transplant (allo-HSCT)
For select fit patients with high-risk disease who respond to initial therapy but are likely to relapse. Replaces diseased marrow with donor stem cells; offers graft-versus-leukemia effect but carries risks (graft-versus-host disease, infections). Cancer.govSplenectomy (spleen removal)
Considered in refractory symptomatic massive splenomegaly causing pain, early satiety, or cytopenias from hypersplenism when medical therapies fail; may improve blood counts and symptoms but increases infection risk (vaccinations/prophylaxis needed). PMCCentral venous port placement
Facilitates safe, repeated infusions of antibodies/chemotherapy and blood draws; reduces vein irritation compared with repeated peripheral IVs. CDCLeukapheresis (selected centers)
Urgent, temporary reduction of extremely high circulating lymphocyte counts to relieve leukostasis symptoms while systemic therapy is arranged (rare in B-cell leukemias but may be used case-by-case). Cancer.govDiagnostic bone marrow biopsy
Not curative, but essential to classify disease, assess genetics (e.g., TP53), and guide targeted therapy choices. NCBI
