Key Takeaway
Note that TORS and TLM are associated with higher 5-year survival rates than RT in supraglottic squamous cell carcinoma.

This meta-analysis synthesized data from 59 studies to compare transoral laser microsurgery (TLM), transoral robotic surgery (TORS), and radiotherapy (RT) for patients with early stage supraglottic squamous cell carcinoma. The primary finding indicates that surgical approaches are associated with improved 5-year overall survival compared to RT, with TORS at 78% and TLM at 72% versus 55% for RT.

Secondary outcomes including tracheostomy rates, gastrostomy rates, and total laryngectomy rates showed similar results across the three treatment modalities. While surgical techniques were associated with better survival, data regarding swallowing outcomes and quality-of-life (QoL) assessments were noted as heterogeneous and not directly comparable between groups.

Several limitations were identified, including the limited and heterogeneous nature of QoL and swallowing data. The authors note that more robust studies involving larger patient populations are required to specifically compare modern intensity modulated RT against TORS. Clinical evidence suggests surgical interventions may offer survival advantages over 2D/3D radiation therapy while maintaining comparable functional outcomes.

This review looked at 59 different studies involving patients with early stage supraglottic squamous cell carcinoma. Researchers compared three main treatment methods: transoral laser microsurgery (TLM), transoral robotic surgery (TORS), and radiotherapy (RT). The goal was to see which method provided the best outcomes for patients over a five-year period.

The findings showed that surgical options had higher survival rates than radiation alone. Specifically, TORS showed a 78% survival rate and TLM showed 72%, while RT showed a 55% survival rate. Other factors like the need for breathing tubes or feeding tubes were similar across all three treatment types.

It is important to note that these results come from a mix of different study types, and more research is needed to compare modern radiation techniques against robotic surgery. Additionally, data regarding quality of life and swallowing were inconsistent across studies. Patients should talk with their doctors to decide which treatment fits their specific needs.

What this means for you:
Surgical methods like TORS and TLM showed higher survival rates than radiotherapy for this specific cancer type.

Common questions

What is the difference in survival between surgery and radiation?

The study found that surgical methods showed higher five-year survival rates compared to radiotherapy. Specifically, transoral robotic surgery (TORS) had a 78% survival rate and transoral laser microsurgery (TLM) had a 72% survival rate. In comparison, the radiation therapy (RT) group had a 55% survival rate.

Are there differences in recovery outcomes like breathing tubes?

The results showed that functional outcomes were similar across all three treatment techniques. This means there was no significant difference between TORS, TLM, and RT regarding the rates of tracheostomy, gastrostomy, or total laryngectomy.

How reliable is the data on quality of life?

The data regarding quality of life and swallowing outcomes were limited. Because these results were gathered from many different types of studies, they were not easy to compare directly. More robust studies are needed to get a clearer picture of these specific factors.

Management of early stage supraglottic squamous cell carcinoma (SCC) evolved with the advent of transoral surgical and new radiation techniques. Current guidelines recommend a single therapeutic modality treatment (either organ-sparing surgery or definitive radiotherapy) yet the optimal approach remains controversial. We conducted a systematic review and meta-analysis to compare long-term (five years) oncological and functional outcomes in early SCC. Two independent reviewers screened the literature available on Pubmed, Embase and Google Scholar (1990-2025). Eligible studies included patients with early SCC (T1-T2/N0-N1/M0), treated with transoral laser microsurgery (TLM), transoral robotic surgery (TORS) or Radiotherapy (RT). A systematic review with comprehensive meta-analysis were performed using RⒸ software. 59 studies were included: 19 RT; 30 TLM, 6 TORS and four on mixed treatment studies. Five-year overall survival favored surgical approaches, particularly TORS, with rates of 78% for TORS, 72% for TLM compared with 55% for RT. Swallowing outcomes and Quality-of-Life (QoL) assessments were heterogeneous and not directly comparable. Available functional data (tracheostomy, gastrostomy and total laryngectomy rates) showed similar results across techniques. Meta-regression analyses adjusting for tumor stage, treatment period and use of adjuvant RT confirmed these findings. TORS and TLM appear to be associated with improved overall survival and comparable functional results compared with 2D/3D RT. Further comparisons of modern (intensity modulated) RT and TORS are needed, based on more robust studies including a larger number of patients. QoL and swallowing data remain limited and heterogeneous, highlighting the need for prospective studies using validated assessment tools, comorbidity analysis and multiple treatment arms.
