Injectable gel capable remedy for cancer
CHICAGO: An injectable gel combining cisplatin, a chemotherapy drug, and epinephrine is effective in treating cancers of the head and neck. This is reported in a new study published in The Archives of Otolaryngology and Head and Neck Surgery. Squamous cell carcinoma is a type of cancer that originates in a particular type of cell found in many different parts of the body. Head and neck squamous cell carcinoma (HNSCC) refers to this type of cancer in the head or neck.
According to background information, HNSCC is diagnosed in about 40,000 Americans each year and more than 600,000 people worldwide. Dr Barry L. Wenig, M.P.H., of Northwestern Medical School, Evanston, Illinois, and colleagues investigated the use of cisplatin/ epinephrine gel injected directly into the tumour in patients with HNSCC.

The researchers conducted two placebo-controlled phase III trials of identical design. One hundred and seventy patients previously treated for their cancers were enrolled (one patient was later excluded). Eighty- nine per cent of the patients were treated with more than one treatment including surgery, chemotherapy and radiotherapy. One hundred nineteen patients received the cisplatin/epinephrine gel, and 59 patients received a placebo gel. Patients' tumours were injected up to six times per week over eight weeks with weekly evaluations.
