Patients  Malignant neoplasm of floor of mouth 
Patients  Malignant neoplasm of gum 
Patients  Malignant neoplasm of other and unspecified parts of tongue 
 
Intervention / Comparator Agent
Modification(s)  
Type  Name  Details 
Intervention  Group II: Study arm (Post-operative adjuvant radiotherapy)  Intervention in the study group (Group II) will be in the form of post-operative adjuvant radiotherapy starting within 8-weeks of primary surgery. The randomised patients will receive Adjuvant radiotherapy 60 Gy in 30 fractions for 30 days over 6 weeks as routinely prescribed according to TMC recommendations and timely implementing it within or by 8 weeks of surgery. 
Comparator Agent  Observation (Arm I)  All patients with early stage tongue cancer will undergo surgery (Wide local excision of the tumor) with ipsilateral neck dissection at minimum. Subsequently, if eligible they will be randomised to Observation vs Adjuvant radiotherapy.In the Arm I, the patients will be observed as per the standard practice. They will be followed up once in three months for three years.

Brief Summary
Modification(s)  

Oral cancer is one of the commonest cancer affecting men in India. Surgery is the preferred initial mainstay of treatment for these patients in our institute. The predominant pattern of failure for oral cancers remains loco-regional recurrence. Various retrospective reports including data from our own institute suggests that depth of invasion is an important factor affecting prognosis in early stage oral cancers. Some centers therefore, advice adjuvant radiotherapy for these tumors based on tumor thickness / depth of invasion alone even in the absence of other adverse prognostic factors. However, no direct evidence exists for the effectiveness of radiotherapy in improving disease-related outcomes in patients with depth of invasion as the only adverse prognostic factor. Given the lack of evidence, none of the international guidelines recommend post-operative adjuvant radiotherapy in early stage oral tongue cancer based on depth of invasion alone.

The aim of this study is therefore to assess the benefit of post-operative adjuvant radiotherapy in patients with an early stage oral squamous cell carcinoma (OSCC). The hypothesis is that postoperative adjuvant radiotherapy would significantly reduce the risk of loco-regional recurrence in patients with tumor thickness ≥5 mm compared to observation alone after definitive surgical treatment of the primary and the neck.
