Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

YEAR 2 SYSTEMS REVIEW - ONCOLOGY

YEAR 2 | PAGE 49B - LINEAGE / MOLECULAR DRIVER -> MALIGNANCY PATTERN -> STAGE / EMERGENCY -> THERAPY / TOXICITY

ONCOLOGY SPINE: CELL OF ORIGIN -> AGE / PRESENTATION -> MORPHOLOGY / FLOW / CYTOGENETICS -> ORGAN INVOLVEMENT -> STAGE / PROGNOSIS -> TARGET / THERAPY -> SIGNATURE TOXICITY OR EMERGENCY. USE MOLECULAR FINDINGS TO EXPLAIN PHENOTYPE, NOT AS ISOLATED TRIVIA. D. ONCOLOGY CLOSED-BOOK REVIEW MAP

LANE	MUST RETRIEVE WITHOUT NOTES	HIGH-DISCRIMINATION TRANSFER
Acute/chronic leukemia	ALL/AML/CML/CLL: lineage, maturity, age, CBC/smear, flow markers, BCR-ABL/APL and marrow-failure consequences.	Discriminate by lineage + maturity + signature molecular/morphologic clue before treatment details.
Lymphoma + plasma cells	Hodgkin/NHL patterns, node biopsy; myeloma/MGUS/Waldenstrom, CRAB, M-spike/free light chains.	Use distribution, B symptoms, biopsy/flow and protein/organ pattern instead of one memorized marker.
MPN / MDS	PV, ET, myelofibrosis, dysplasia; JAK2/CALR/MPL/BCR-ABL; thrombosis and transformation.	Separate clonal overproduction from marrow failure/dysplasia and from reactive elevations.
Cancer biology / staging	Oncogenes, tumor suppressors, DNA repair, invasion/metastasis, grade vs stage, screening vs diagnostic markers.	Interpret molecular drivers and pathology in the context of tissue behavior and spread.
Therapy + emergencies	Cell-cycle chemotherapy, targeted/immunotherapy, rescue/monitoring; neutropenic fever, TLS, leukostasis, hyperCa, SVC/cord compression/tamponade.	Recognize what requires immediate stabilization/treatment before a complete oncologic workup.

E. TOP 10 MOST-MISSED SYSTEM CONCEPTS - #4 TO #6

# / CONCEPT	DEEP EXPLANATION	WHY STUDENTS MISS IT	EASIEST CLUE
4. Hematologic malignancy is lineage + maturity + context	Leukemia and lymphoma questions become tractable when you identify myeloid vs lymphoid lineage, acute vs chronic maturity, patient age, CBC/smear/flow and defining molecular event. The same white-cell count can represent very different biology.	Students jump to the famous cytogenetic association before deciding what cell population is abnormal.	Ask which lineage, how mature, and what age/presentation fits?
5. Stage and grade answer different questions	Grade describes how abnormal/aggressive the tumor appears histologically; stage describes anatomic extent/spread and often dominates prognosis/management. Tumor markers can support diagnosis/monitoring but rarely replace tissue/anatomic context.	Learners blend grade, stage and marker values into one “severity” concept.	Remember grade = appearance; stage = spread.
6. Cancer questions often hide an emergency or treatment	Neutropenic fever, tumor lysis, leukostasis, hypercalcemia, cord/SVC compression and treatment toxicities can change the	Recognition of the malignancy feels like the endpoint, so urgency and drug toxicity are missed.	Ask what can injure or kill the patient first - disease burden,
toxicity	next step before the underlying cancer is fully characterized.		obstruction, metabolic collapse, infection, or therapy?

SCHOOL-EXAM GATE	BOARD / COMLEX TRANSFER
• Differentiate ALL/AML/CML/CLL using lineage, maturity and defining data. • Use age + biopsy/flow/protein patterns for lymphoma/plasma-cell disease.	• Connect driver mutation -> cell behavior -> phenotype -> therapy target. • Separate grade, stage and biomarker roles.
• Recognize oncologic emergencies before management distractors. 2026/27 systems-review expanded edition - align with school objectives and verify official exam updates before testing	• Predict signature treatment toxicities from mechanism.
