Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. Although rituximab therapy improves clinical outcome, some patients develop resistant DLBCL; however, the genetic alterations in these patients are not well documented. To identify the genetic background of refractory DLBCL, we conducted whole-exome sequencing and transcriptome sequencing for six patients wit...

Refractory angina pectoris is defined as angina refractory to optimal medical treatment and standard coronary revascularization procedures. Despite recent therapeutic advances, patients with refractory angina pectoris are not adequately treated. Spinal cord stimulation is a minimally invasive and reversible technique which utilizes electrical neuromodulation by means of an electrode implanted i...

BACKGROUND The current standard of care for relapsed and refractory acute lymphoblastic leukemia (ALL) is combination chemotherapy. CASE PRESENTATION We report a case of highly refractory ALL who was treated with blinatumomab. The ALL in this patient relapsed within a month after completion of hyperCVAD regimen and was refractory to high dose mitoxantrone/cytarabine and CLAG regimens. CONCL...

Prostate cancer cells depend on androgens and the androgen receptor (AR) for survival. However, after androgen ablation therapy, tumors relapse to an androgen-refractory state. To determine whether the androgen receptor is critical for proliferation of androgen-refractory prostate cancer cells, we disrupted the activity of the androgen receptor with an antibody and an AR mRNA hammerhead ribozym...

BACKGROUND Primary refractory disease is a main challenge in the management of non-Hodgkin's Lymphoma (NHL). This survey was performed to define the rate of refractory disease to first-line therapy in B and T-cell NHL subtypes and the long-term survival of primary refractory compared to primary responsive patients. METHODS Medical records were reviewed of 3,106 patients who had undergone prim...

Background. Most patients with metastatic prostate cancer are endocrinologically treated with LHRH agonist, but finally castration-refractory and hormone-refractory cancers occur. Serum testosterone levels get low to "the castration level" by LHRH agonists but may not get low enough against castration-refractory prostate cancer. Methods. As case series, twelve patients suffering from hormone-re...

Refractory Epilepsy (R.E.) is a condition where all antiepileptic drugs (AEDs) fail to provide adequate seizure control. To diagnose R.E., false cases of refractoriness need to be carefully excluded. There are several predictors of refractoriness. The treatment options in R.E. are resective surgery, ketogenic diet and vagal nerve stimulation. The roles of newer AEDs are also promising. The futu...

The term resistant hypertension has been used since the early 1960s to identify patients with difficult-to-treat hypertension, meaning mostly, resistance to pharmacological therapy. In the 5 decades since the term was seemingly first applied, resistant hypertension has been consistently defined as failure to control high blood pressure despite of use of ≥3 antihypertensive agents of different c...

CASE PRESENTATION A 51-year-old woman with a history of an olfactory neuroblastoma treated with radiation, chemotherapy, and surgical resection 13 years ago was admitted for evaluation and treatment of persistent nausea, vomiting, fatigue, and dehydration. The patient suffered from significant cosmetic defects since resection of the neuroblastoma, and had undergone a left eyebrow lift 1 year be...
