Detailed Description
Surgery, when possible offers the best chance of cure for cancer of the thyroid gland. Surgery for thyroid cancer involves removal of the thyroid gland along with removal of the lymph nodes which drain the gland. After surgery most patients will receive radio-iodine treatment to diagnose and treat any spread of the cancer in the body. Most thyroid cancers will have good outcomes with the above mentioned treatment. However, in advanced thyroid cancer there is a higher chance of recurrence even with surgery and radio iodine. Surgery for recurrence of these cancers is very morbid This may entail surgeries which may also involve removing portions of the voice box and food pipe. You may therefore develop and discomfort or inability to eat or speak.
Radiation therapy can be given to the neck along with radio-iodine therapy to decrease these re occurrences of the cancer. A number of studies have shown a benefit with the use of radiation therapy in advanced cases of thyroid cancer. However, the side effects of radiation, if any, have not been well documented. This study is being done to assess the impact of radiation on the outcome of cancer and the exact side effects of radiation therapy. If the side effects are not too many, then radiation therapy can be used to decrease the chances of recurrence in the neck after thyroid.
In this study, patients undergoing total thyroidectomy for thyroid cancer will be assessed for high risk features on the histopathology report and the intra operative findings. Those with advanced thyroid cancer as per the eligibility criteria will be counselled and consented for the study. Those patients willing to participate in the study will be randomised to either receive only surgery and radio-iodine or surgery, radio-iodine and external beam radiation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Intensity Modulated radiotherapy
In this Arm, after surgery, patient will receive radio-iodine treatment as per guidelines, 6-8 weeks after surgery. The patient will receive adjuvant radiation therapy about 8-10 weeks after completion of initial surgery. The duration of this radiation therapy will be approximately 45 days. : The goal of the treatment plan would be to encompass the PTV subclinical disease with a dose of 54-60 Gy and the PTV of the gross disease with 70-74 Gy while sparing as much of the aforesaid critical structures as possible. The maximum permissible point doses to the spinal cord will be limited to 46 Gy. IMRT planning and delivery will be carried out on the Tomotherapy Hi Art System. |

The maximum permissible point doses to the spinal cord will be limited to 46 Gy. IMRT planning and delivery will be carried out on the Tomotherapy Hi Art System.
This intervention is of no interest

Other: Surgery alone
In this Arm, after surgery patient will receive radio-iodine treatment as per guidelines, 6-8 weeks after surgery.
Patient under surgery arm will receive no further treatment after surgery and radio-iodine therapy and will be kept on a routine follow up
