ABSTRACT

PURPOSE: To identify the occurrence of clinical and subclinical hypothyroidism among head and neck cancer patients receiving radiation to the neck and to justify routine performing of thyroid function tests during follow-up. MATERIALS AND METHODS: This is a prospective nonrandomized study of 45 patients of head and neck cancer, receiving radiotherapy (RT). Thyroid stimulating hormone and T4 estimations were done at baseline and at 4 months and 9 months following RT. RESULTS: Of the 45 patients, 37(82.2 %) were males and eight (17.8 %) were females. All patients received radiation to the neck to a dose of >40Gy. 35.6% received concurrent chemotherapy. Two patients underwent prior neck dissection. Fourteen patients (31.1%) were found to have clinical hypothyroidism (P value of 0.01). Five (11.1%) patients were found to have subclinical hypothyroidism with a total 19 of 45 (42.2%) patients developing radiation-induced hypothyroidism. Nine of 14 patients with clinical hypothyroidism were in the age group of 51 to 60 years (P=0.0522). Five of 16 patients who received chemoradiation and nine of 29 who received RT alone developed clinical hypothyroidism. Above 40 Gy radiation dose was not a relevant risk factor for hypothyroidism. CONCLUSION: Hypothyroidism (clinical or subclinical) is an under-recognized morbidity of external radiation to the neck which is seen following a minimum dose of 40 Gy to neck. Recognizing hypothyroidism (clinical or subclinical) early and treating it prevents associated complications. Hence, thyroid function tests should be made routine during follow-up.

ABSTRACT

Intraocular metastatic tumor is the commonest intraocular malignancy in adults, with uveal tract the commonest site. In nearly 85% of cases the choroid is the afflicted site due to its vascularity. Breast and lung are the common primaries. In breast primaries, this could be the first metastatic disease. This condition should always be kept in mind in patients with visual symptoms. Fundus examination, ultrasonography and CT/MRI of the orbit help in diagnosis. Early recognition and timely treatment can save the visual function thus imparting good quality of life to the patient. External beam radiotherapy is a good local form of treatment. Hormone therapy in hormone receptor positive tumors can have additional benefits. Here we report a case of unilateral solitary choroid metastasis in a case of breast cancer treated with external beam radiotherapy.
