Keytruda (Pembrolizumab) Shows Promise for Advanced Merkel Cell Carcinoma

By Stacy SimonResults of a small clinical trial show that more than half the patients with Merkel cell carcinoma, a rare but aggressive type of skin cancer, improved when they took the immunotherapy drug Keytruda (pembrolizumab). And the improvement appears to be lasting longer than would be expected with standard treatment. This is a significant finding because there are currently no drugs that have been approved by the US Food and Drug Administration (FDA) to treat Merkel cell carcinoma. Researchers studying Keytruda and other drugs are trying to provide more treatment options for people with this type of skin cancer.While skin cancer is by far the most common type of cancer in the United States, Merkel cell carcinoma is not common. It’s thought that about 1,500 cases of Merkel cell carcinoma are diagnosed in the United States each year. It tends to spread quickly and can be hard to treat. While it often responds to chemotherapy, the improvement usually lasts only about 3 months.Researchers from cancer research centers across the US studied 25 people who took part in the clinical trial. All had Merkel cell carcinoma that had spread, and none had received chemotherapy. They were all given Keytruda. Fourteen of them (56%) improved, including 4 who had a complete response, meaning all signs of their cancer disappeared. After 6 months, 12 of the 14 were still doing well.The study was presented April 19 at the annual meeting of the American Association for Cancer Research ...

CONCLUSION: Extensive research have been carried out on various process for preparing Bortezomib and composition thereof. This type of dynamic research will clear the path for many generic players in the United States which lead in reduction of price of the composition and thereby enhancing global health care at cheaper prices.

OBJECTIVES: Aromatase inhibitors are the first-choice drugs for the treatment of hormone sensitive breast cancer. However, in addition to the scarcity of studies, there are controversies about their effects on vaginal epithelial cell proliferation in rats, especially those in persistent estrus. METHODS: To investigate vaginal epithelial cell proliferation by Ki-67 antigen expression, persistent estrus was induced in 42 randomly selected rats. These rats were randomly divided into 2 groups: group I (control, n=21), which received 0.1 mL of propylene glycol (vehicle) daily, and group II (experimental, n=21), which received 0...

Authors: Okamura K, Bandai S, Fujikawa M, Sato K, Kitazono T Abstract The treatment of Graves' hyperthyroidism (GD) complicated with malignancy is challenging, as anti-thyroid thionamide drugs (ATDs) and anti-cancer chemotherapy are both associated with a risk of neutropenia. Treatment with conventional ATDs, radioactive iodine (RAI) or potassium iodide (KI) was attempted in 8 patients with malignancy (34-80 years of age; 2 males and 6 females) in whom GD had been fortuitously diagnosed during a detailed systematic examination. Three patients requiring surgery were initially treated conventionally with methylmercap...

The objective of this study was to test the value of adding a maximal inspiratory manoeuvre to basic spirometry to differentiate COPD and BA. One hundred forty-three COPD patients and 142 BA patients had measurements of maximal inspiratory and expiratory flow during routine spirometry. Parameters from these tests were used to assess diagnostic accuracy using receiver-operating characteristic (ROC) analyses followed by logistic regression. The association of two independent parameters were analyzed using linear regression analyses. Results show that forced expiratory volume in one second/forced vital capacity (FEV1/FVC%)

Oral intake of cancer agents is sometimes compulsory (no i.v. equivalent) or is preferred by the patient or the physician. Although oral chemotherapy facilitates the treatment of oncology patients, the treatment diversity, risk of pharmaceutical interactions and monitoring of side effects are potentially challenging and need to be fully acknowledged by the physician. We offer here a literature review of the indicat...

There is limited knowledge regarding the role and impact of USP19 in cancer, particularly clear cell renal cell carcinoma (ccRCC). To examine the function of USP19 in ccRCC, The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases were examined to determine USP19 mRNA expression levels. USP19 mRNA levels were sig...
