I now have excellent textbook evidence. Let me compile the comprehensive management plan for this patient.
Next Plan of Management: Squamous Cell Carcinoma of Left Oral Tongue
Patient Summary from Documents
| Parameter | Finding |
|---|---|
| Patient | Gitanjali Kumbhar, 40F |
| Biopsy (Jan 2026) | SCC - border of tongue (BBMCH Balangir) |
| MRI (Aug 7, 2026) | Left hemi-tongue mass, 29 x 15 x 28 mm |
| Depth of Invasion (DOI) | 7.1 mm |
| Medial margin | 9.1 mm from midline septum - NOT crossing |
| Posterior extent | NOT involving posterior 1/3rd / base of tongue |
| Floor of mouth | Abutting - no infiltration |
| Lymph nodes | Bilateral Level II-III, largest 8.1 mm SAD - likely reactive |
TNM Staging (AJCC 8th Edition)
Applying criteria from Cummings Otolaryngology Head and Neck Surgery:
- T staging: Tumor >2 cm (29 mm largest dimension) AND DOI 7.1 mm (>5 mm, ≤10 mm) = T2
- N staging: Bilateral subcentimetric nodes, radiologically reactive, no definite metastatic node = cN0
- M staging: No distant disease on current imaging = cM0
Clinical Stage: T2 N0 M0 - Stage II
Next Plan of Management
1. Pre-treatment Workup (if not yet done)
- CT chest - to rule out pulmonary metastases (complete staging)
- Dental evaluation - pre-radiation dental clearance
- Nutritional assessment - dietitian consult, Ryle's tube/PEG planning
- Anaesthetic fitness - fitness for surgery
- Multidisciplinary tumor board (MDT) review - surgical oncology, radiation oncology, medical oncology, speech therapy
2. PRIMARY TREATMENT: Surgery (Standard of Care)
Per Bailey & Love's Short Practice of Surgery, 28th Edition:
"Primary surgery, with/without adjuvant (chemo)radiotherapy, is the standard" for oral cavity SCC.
Per Cummings Otolaryngology:
"The treatment of choice for early-stage lesions... is transoral wide local excision."
Procedure: Partial Hemiglossectomy (Left)
- Transoral or pull-through approach
- Wide local excision with 1.0-1.5 cm free margins (aim for histological margin >5 mm)
- Intraoperative frozen-section margin assessment
- The lesion does NOT involve the floor of mouth - primary closure or split-thickness skin graft may suffice
- If significant floor of mouth involvement at surgery: radial forearm free flap (RFFF) or anterolateral thigh (ALT) flap for reconstruction to prevent tongue tethering
3. NECK MANAGEMENT: Elective Neck Dissection (MANDATORY)
Per K.J. Lee's Essential Otolaryngology:
"For primary tumors with greater than 4-mm depth of invasion, elective treatment of the neck with either surgery or radiation is recommended." "Selective neck dissection should include at least levels I-III (supraomohyoid neck dissection)."
This patient has DOI = 7.1 mm - significantly above the 4 mm threshold.
- Selective Neck Dissection, Levels I-IV (ipsilateral left) - minimum levels I-III
- Byers et al. demonstrated 15.8% "skip" metastases to Levels III-IV, bypassing Levels I-II, supporting dissection of Level IV as well
- Contralateral neck (right): The lesion is 9.1 mm from the midline - close enough that contralateral elective dissection should be discussed in MDT. If <1 cm from midline or crosses it, bilateral neck dissection is indicated.
Per Cummings: The most frequent metastatic sites for oral tongue SCC are upper jugular nodes (73%), submandibular nodes (18%), middle jugular nodes (18%).
4. ADJUVANT THERAPY DECISION (Post-surgical pathology-driven)
Per Bailey & Love and Cummings Otolaryngology:
Indications for Adjuvant Radiotherapy (≥60 Gy) - if any ONE major OR two minor criteria:
| Criteria | Type |
|---|---|
| Positive/close margins (<1 mm) | Major |
| Extranodal extension (ENE) | Major |
| Margin 1-4.9 mm | Minor |
| Multiple positive lymph nodes | Minor |
| Largest node >3 cm | Minor |
| Lymphovascular invasion (LVI) / Perineural invasion (PNI) | Minor |
| T3/T4 pathological stage | Minor |
Indications for Adjuvant CHEMORADIOTHERAPY (Cisplatin-based CRT):
- Positive surgical margins AND/OR extranodal extension (ENE)
- Based on RTOG 9501 and EORTC 22931 landmark trials (per Bailey & Love)
5. SPEECH AND SWALLOWING REHABILITATION
- Speech-language pathologist (SLP) assessment pre- and post-operatively
- Palatal augmentation prosthesis if significant tongue volume loss
- Swallowing therapy post-surgery
6. FOLLOW-UP PLAN
| Timeline | Action |
|---|---|
| 1-3 months | Clinical examination + wound check |
| 3 months | Post-treatment MRI neck/tongue |
| Every 3-6 months (Years 1-2) | Clinical exam ± imaging |
| Every 6-12 months (Years 3-5) | Clinical exam |
| Annual TSH | If neck irradiated |
Summary Algorithm for This Patient
T2 N0 M0 Oral Tongue SCC (DOI 7.1 mm)
↓
Partial Hemiglossectomy (Left) + Ipsilateral Selective Neck Dissection (Levels I-IV)
↓
Await final histopathology (margins, nodes, PNI/LVI, ENE)
↓
Negative margins, pN0 → Observation ± PORT if minor risk factors
Positive margins / ENE → Adjuvant CRT (Cisplatin-based)
Close margins / N+ without ENE → Adjuvant RT alone (60-66 Gy)
Prognosis: 5-year survival for Stage I-II oral tongue SCC is 60-75% (K.J. Lee's Essential Otolaryngology). Occult nodal metastases carry a fivefold increased risk of disease-specific death; END improves disease-specific survival in T2 N0 cases. - Cummings Otolaryngology Head and Neck Surgery
