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. |
