Cancer Surgery: Curative Intent, Staging, Types, and Multimodal Integration

Surgery remains the primary curative modality for most solid tumors. Its role extends beyond resection to staging, palliation, and enabling multimodal therapy.

Curative Surgery

• Goal: Complete macroscopic and microscopic resection (R0 resection: negative margins).
• Applicable to: Localized/regional disease (Stage I–III for many cancers).
• Cure rates: High for early-stage breast, colon, melanoma, testicular, thyroid, etc.

Surgical Staging and Diagnosis

• Defines T (tumor size/invasion), N (nodal status), M (metastasis) — TNM staging.
• Lymphadenectomy (sentinel node biopsy or formal dissection) critical for nodal staging.
• Tissue for molecular profiling (ER/PR/HER2, KRAS, MSI, PD-L1, NTRK) guiding adjuvant/targeted therapy.

Types of Cancer Surgery

Multidisciplinary Integration

• Neoadjuvant therapy: Shrink tumor → enable resection, assess response, treat micromets early (breast, rectal, esophageal, sarcoma).
• Adjuvant therapy: Post-op chemo/radiation/targeted/immunotherapy based on pathology.
• Tumor Board: Surgeon, medical/rad onc, path, rads, genetics, nursing — consensus plan.

Perioperative Optimization

• Prehabilitation: exercise, nutrition, smoking cessation, anemia correction.
• ERAS (Enhanced Recovery After Surgery) protocols: reduce complications, LOS.
• Minimally invasive (laparoscopic, robotic) when oncologically equivalent.

Quality Metrics

• R0 resection rate, lymph node harvest, margin distance, 30-day mortality, 5-year survival.
• High-volume centers/surgeons → better outcomes for complex resections.

Surgery is not standalone; it is the cornerstone of a multimodal strategy tailored to tumor biology and patient factors.

Type	Description	Examples
Diagnostic biopsy	Tissue confirmation	Core needle, excisional, endoscopic
Local excision	Tumor + narrow margin	Small breast lump, early melanoma, polyp
Wide local excision	Tumor + 1–2 cm margin	Breast conservation, soft tissue sarcoma
Radical/composite resection	Tumor + organ + nodes + adjacent structures	Whipple (pancreas), cystectomy (bladder), esophagectomy
Mohs micrographic	Layer-by-layer with frozen section margin control	High-risk BCC/SCC (face, hands)
Debulking / Cytoreduction	Reduce tumor burden (not curative alone)	Advanced ovarian, peritoneal metastases
Palliative	Relieve obstruction, bleeding, pain	Stenting, bypass, kyphoplasty
Prophylactic	Risk reduction in high-risk genetics	Mastectomy (BRCA), colectomy (FAP)
Reconstructive	Restore form/function after ablation	Breast recon (implant/flap), mandible fibula flap
