A comparative study of whole brain radiotherapy with concomitant thalidomide versus whole brain radiotherapy alone in brain metastases.

BACKGROUND: Brain metastasis increases morbidity and mortality in cancer patients. This study was undertaken to compare tumor response and treatment-related toxicities in patients treated with orally administered thalidomide concomitantly with whole brain radiotherapy to whole brain radiotherapy alone in brain metastases. METHODS: This randomized control trial was conducted in radiation oncology department, RIMS among 42 patients of brain metastases distributed in two study arms during the period August 2018 to July 2020. Twenty patients in Arm-A received whole brain radiotherapy to a dose of 3,750 cGy in 15 fractions with concomitant oral thalidomide 200 mg daily in first week and 400 mg/day from second week of radiation onward till the end of radiotherapy, whereas 20 patients of Arm-B received whole brain radiation of 3,750 cGy in 15 fractions alone. RESULTS: Patient characteristics were comparable. Median central nervous system progression free survival was 2 months for Arm-A and 3 months for Arm-B, whereas median overall survival study was 4 months for Arm-A and 3 months for Arm-B. Overall response rate in Arm-A was 56% and in Arm-B was 44%. Treatment-related toxicities were more in arm-A but were manageable. CONCLUSION: Addition of thalidomide to whole brain radiotherapy makes no significant difference. Though not statistically significant, but still, Arm-A had shown some percentage benefits. Further studies with larger sample sizes should be done.

Capecitabine and oxaliplatin induced Steven-Johnson syndrome following nivolumab in a patient of metastatic esophageal carcinoma.

Stevens-Johnson syndrome presents as mucocutaneous blistering and sloughing, which may follow a devastating clinical course. Although Stevens-Johnson syndrome has been reported following the administration of anticancer drugs, only a few cases induced by cytotoxic anticancer drugs, administered after immune checkpoint inhibitors, have been reported. The present report describes a case of Stevens-Johnson syndrome caused by capecitabine and oxaliplatin (CAPEOX) combination chemotherapy, in a patient with esophageal squamous cell carcinoma, who had been previously treated with nivolumab.
