ABSTRACT

Background: Alemtuzumab (ATZ) is an anti-CD52 humanized monoclonal antibody indicated for treating highly active relapsing-remitting MS (RRMS). It alters the regulation of the immune system by depleting circulating lymphocytes. Changes in blood cell count, infusion-related reactions, and changes in vital parameters can be seen in the early period with ATZ. Aim: Changes in blood tests, serum tests, vital parameters, and characteristics of infusion-associated reactions (IARs) observed during the first course of ATZ treatment and thereafter were evaluated. Materials and methods: The systolic blood pressure (SBP), diastolic blood pressure (DBP), fever, heart rate (HR), changes in blood and serum tests, and IARs developed after the first course of 23 patients with RRMS who received ATZ treatment were evaluated by comparing the results of 26 patients with RRMS who received only intravenous methylprednisolone. Results: Mean age was 36.60 ± 8.98, 73.9% female (n = 17), diagnosis time was 8.52 ± 3.64 years, pre-EDSS: 3.93 ± 1.80. No significant difference was found in vital parameters except for sub-febrile fever that developed on the first day. The number of white blood cells increased significantly after the first day. The hemoglobin level did not change. Lymphocyte (very high) and platelet (mild) counts decreased starting from the first days, and eosinophil (very high) and monocyte (moderate) counts decreased from the third day. There were no significant changes in liver enzymes, thyroid function tests, serum urea, creatinine, and lipid profile during 1-year follow-up. The IAR rate was 95.6% and occurred most frequently on the second and third days. The most common are dermatological findings (52%), headache (20%), pain (10%) and fatigue (8%). Conclusion: Alemtuzumab has no appreciable effect on vital parameters during infusion. However, these changes are not clinically correlated, even if there is. Headache in the first days, dermatological (most common) findings, pain, and fatigue are seen in the following days. Most IARs can be resolved with symptomatic treatment and close follow-up. Lymphocytes, eosinophils, and monocytes are significantly reduced and return to baseline levels towards the end of the first year. The first year does not cause significant pathologies in other serum parameters. However, after the first year, watch out for associated autoimmune pathologies, especially thyroid involvement.

ABSTRACT

Background Thyroid cancer is one of the five most common cancers causing bone metastasis. If there is an increase in serum thyroglobulin-antithyroglobulin levels in differentiated thyroid cancer or calcitonin levels in medullary thyroid cancer, patients should be evaluated for recurrence and distant metastasis. The skeleton is the second most common site of distant metastasis in thyroid cancer after the lung. Bone metastases cause pain, fractures, and spinal cord compression, severely reducing the quality of life. They are associated with poor prognosis. Bone metastases severely reduce the quality of life. This study aimed to retrospectively evaluate the diagnosis and follow-up of patients with thyroid cancer with bone metastases diagnosed at our center. Methodology A total of 1,390 patients diagnosed with thyroid malignancy at our center between 2010 and 2023 were reviewed retrospectively. The study included 27 patients with differentiated and medullary thyroid cancer who had bone metastases. Results Of 27 patients, 19 (70.4%) had differentiated and eight (29.6%) had medullary thyroid cancer. Papillary thyroid cancer constituted 22.2% (n = 6) and follicular thyroid cancer constituted 14.8% (n = 4) of the cases. Papillary carcinoma follicular variant, oncocytic, and poorly differentiated thyroid cancer were diagnosed with similar frequency, each accounting for 11.1% (n = 3). It was found that vertebrae were most commonly involved, followed by the pelvis, sternum, costae, femur and patella, shoulder and humerus, cranium, and scapula. The five-year survival rate was 72%, and the 10-year survival rate was 53%. Conclusions The number of patients with papillary cancer was the highest, but the rate of bone metastases was the lowest in this group. The highest rate of bone metastases was found in patients with poorly differentiated, oncocytic, medullary, follicular, and papillary cancer, respectively. The results obtained in this study reveal the necessity and importance of bone metastasis evaluation in patients with thyroid cancer.
