A 62-year-old woman from Mumbai presents with postmenopausal bleeding and pelvic pain for 4 months. She has a BMI of 32 kg/m², hypertension, and no prior hormone replacement therapy. Transvaginal ultrasound shows an endometrial mass with invasion into the myometrium and extension into the cervical canal. Staging MRI confirms cervical stromal invasion but no parametrial involvement. Pelvic lymph nodes are not enlarged. What is the most appropriate next step in management?

Explanation

## Management of Stage II Endometrial Cancer **Key Point:** Stage II endometrial cancer (cervical stromal invasion without parametrial involvement) requires **radical hysterectomy** rather than simple total hysterectomy to ensure adequate removal of cervical tissue and parametrial margins. ### Surgical Approach Decision Tree ```mermaid flowchart TD A[Endometrial cancer with cervical stromal invasion]:::outcome --> B{Parametrial involvement?}:::decision B -->|Yes| C[Radical hysterectomy + BSO + PLND]:::action B -->|No| D[Still cervical stromal invasion]:::outcome D --> E[Radical hysterectomy + BSO + PLND]:::action F[Stage IA/IB without cervical involvement]:::outcome --> G[Total hysterectomy + BSO + PLND]:::action ``` ### Comparison: Total vs. Radical Hysterectomy | Feature | Total Hysterectomy | Radical Hysterectomy | |---------|-------------------|----------------------| | **Indications** | Stage IA, IB (no cervical involvement) | Stage II (cervical stromal invasion) | | **Cervical removal** | Minimal (just isthmus) | Entire cervix + parametrial tissue | | **Parametrial dissection** | None | Yes, up to pelvic sidewall | | **Morbidity** | Lower | Higher (bladder/bowel dysfunction) | | **Oncologic control** | Adequate for early stage | Required for cervical involvement | **Clinical Pearl:** In this patient, MRI confirms **cervical stromal invasion** (stage II), which mandates radical hysterectomy. Parametrial lymph nodes are not enlarged, but lymph node dissection is still indicated for complete staging. **High-Yield:** Cervical stromal invasion = Stage II = Radical hysterectomy. Do NOT confuse with parametrial invasion (which is stage IIIB and may require additional imaging/neoadjuvant therapy). ### Lymph Node Dissection Pelvic lymph node dissection is standard in endometrial cancer surgery for: - Accurate staging (IIIC1 if pelvic nodes positive) - Prognostic information - Guiding adjuvant therapy decisions Para-aortic lymph node dissection may be considered if pelvic nodes are involved or if high-risk histology. **Mnemonic:** **Stage II = Cervical stromal invasion = Radical (not total) hysterectomy** [cite:FIGO 2009 Endometrial Cancer Staging; NCCN Endometrial Cancer Guidelines 2023]
