Iranian scientist discovers cigarette raises cancer cell life

TEHRAN (ISNA)- An Iranian scientist at the US Memorial Sloan Kettering Cancer Center has founded that exposure of people suffering renal cell carcinoma to cigarette increases life of cancer cells.

Behfar Ehdaei and his colleagues have investigated exposure of 1625 people to cigarette, conducting one-variable analysis, and founded out that extreme smoking is totally associated with the disease.

Moreover, results of the research showed that the number of smokers who have recently started smoking and died was considerably higher than the non-smokers. The researchers also recommended quit smoking treatment programs.

The results of the research have been published in Urology Journal.

Renal cell carcinoma (RCC, formerly known as hypernephroma) is a kidney cancer that originates in the lining of the proximal convoluted tubule, the very small tubes in the kidney that transport GF (glomerular filtrate) from the glomerulus to the descending limb of the nephron. RCC is the most common type of kidney cancer in adults, responsible for approximately 80% of cases.

It has been described as being among the most lethal of all the urological cancers. Initial treatment is most commonly a radical or partial nephrectomy and remains the mainstay of curative treatment. Where the tumor is confined to the renal parenchyma, the 5-year survival rate is 60-70%, but this is lowered considerably where metastases have spread. It is relatively resistant to radiation therapy and chemotherapy, although some cases respond to immunotherapy. Targeted cancer therapies such as sunitinib, temsirolimus, bevacizumab, interferon-alpha, and sorafenib have improved the outlook for RCC.
