ABS CGSO study plan

ABS CGSO · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Diagnosis of cancer, including complex presentations and rare or unusual cancers

  • Map the diagnostic pathway for the ten most common solid tumors from presentation to tissue diagnosis

  • Differentiate staging systems (TNM, Ann Arbor, FIGO, Rai) by cancer type and state which applies to each

  • Explain the role and limitations of imaging modalities (CT, MRI, PET, ultrasound) in initial workup

  • Identify red-flag presentations that should trigger urgent referral

Your checkpoint

A one-page diagnostic algorithm per cancer type for five common cancers, with staging system labeled

Week 2

Diagnosis of cancer, including complex presentations and rare or unusual cancers

  • Describe workup of complex presentations: unknown primary, paraneoplastic syndromes, and spinal cord compression

  • Outline diagnostic approach to rare cancers (sarcoma, neuroendocrine, GIST, CNS tumors)

  • Distinguish benign from malignant findings on pathology reports and interpret immunohistochemistry panels

  • Explain tumor markers: when they aid diagnosis versus monitoring

Your checkpoint

A comparison table of five rare/complex presentations with first-line diagnostic steps and pitfalls

Week 3

Diagnosis of cancer, including complex presentations and rare or unusual cancers & Multidisciplinary treatment of the cancer patient

  • Consolidate Domain 1 by teaching back the diagnostic framework for a complex case

  • Map the multidisciplinary team roles (surgical, medical, radiation oncology, pathology, radiology, palliative care)

  • Describe how tumor board decisions are structured and documented

  • Identify which cancers are managed primarily by surgery versus systemic therapy versus radiation

Your checkpoint

A written tumor board summary for a hypothetical complex case listing each discipline's recommendation

Week 4

Multidisciplinary treatment of the cancer patient

  • Compare systemic therapy classes (cytotoxic, targeted, immunotherapy, endocrine) by mechanism and toxicity profile

  • Explain principles of radiation therapy: intent, fractionation, and common acute/late effects

  • Outline surgical oncology principles including margins, lymph node sampling, and neoadjuvant rationale

  • Describe supportive care integration across the treatment trajectory

Your checkpoint

A treatment-modality matrix matching cancer type to standard first-line approach with rationale

Week 5

Multidisciplinary treatment of the cancer patient & Rehabilitation required by patients with cancer

  • Apply treatment sequencing to a relapsed or metastatic scenario

  • Identify treatment-related toxicities requiring rehabilitation referral (neuropathy, lymphedema, deconditioning)

  • Explain survivorship care planning and transition from active treatment

  • Describe fertility preservation and its timing relative to treatment start

Your checkpoint

A survivorship care plan template covering surveillance, late effects, and rehab referrals

Week 6

Rehabilitation required by patients with cancer

  • Assess functional status using validated tools (ECOG, Karnofsky, ADL/IADL) and interpret scores for rehab planning

  • Design rehabilitation programs for lymphedema, cancer-related fatigue, and chemotherapy-induced peripheral neuropathy

  • Describe cognitive rehabilitation and psychosocial support for patients and caregivers

  • Explain return-to-work and community reintegration planning

Your checkpoint

Three goal-oriented rehab plans (lymphedema, fatigue, neuropathy) with measurable functional targets

Week 7

Rehabilitation required by patients with cancer & Cancer prevention, outreach, and research

  • Integrate rehab planning into a multidisciplinary case from earlier weeks

  • Explain primary, secondary, and tertiary prevention with cancer-specific examples

  • Describe screening guidelines and their evidence basis for major cancers

  • Identify modifiable risk factors and behavioral counseling approaches

Your checkpoint

A prevention and screening summary table by cancer type with guideline source and interval

Week 8

Cancer prevention, outreach, and research & Diagnosis of cancer, including complex presentations and rare or unusual cancers & Multidisciplinary treatment of the cancer patient & Rehabilitation required by patients with cancer

  • Explain clinical trial phases, informed consent, and research ethics

  • Describe outreach strategies addressing access, disparities, and health literacy

  • Synthesize all four domains in timed practice cases

  • Identify and remediate personal weak areas from practice performance

Your checkpoint

A timed 60-question mixed-domain practice set with a written error log and remediation list

Milestones

Week 2: Complete a 20-question diagnostic-domain self-quiz and score at least 70%

Week 4: Present a full multidisciplinary treatment plan for one complex case, covering all four disciplines

Week 6: Demonstrate functional assessment scoring on three practice vignettes with correct tool selection

Week 8: Achieve at least 75% on the timed mixed-domain practice set with all missed items logged and reviewed
