Mesothelioma Research Round-Up

A Rare Case of Mesothelioma Most often, mesothelioma is associated with a tumor of the pleura of the lungs, which is the tissue lining the lungs. However, tumors can also attack the mesothelium of other parts of the body. One man discovered that he had mesothelioma of the testis. A man approached his physician with swelling in his left leg that was painless. Upon examination, the doctor also noted that the man’s left testicle was enlarged. An ultrasound on the region showed that the man had a tumor, which suggested that it was malignant. Malignancies in mesothelioma of the tunica vaginalis of the testis are very rare, but this man’s condition highlighted to doctors to be aware of keeping it in mind for a possible diagnosis whenever a swollen mass is found in the testis if there is no history of trauma which might cause it. A needle aspiration of the mass coupled with an ultrasound of the area will help to finalize a diagnosis. Should a malignant tumor be found, surgery is the most common treatment. Good News on Mesothelioma Rates In a study conducted in the United States, rates of mesothelioma were examined and concluded to be dropping.

The group looked at the rates of mesothelioma through the National Cancer Institute’s Surveillance Epidemiology and End Results registry data from 1973 to 2002. They took into account age by examining age-specific and age-adjusted rates of the three major forms of mesothelioma: pleural, total, and peritoneal. The rates of incidence of mesothelioma were also looked at in those who began working after limits on asbestos in the workplace were established by the Occupational Safety and Health Administration (OSHA). While they did note great gender differences in developing mesothelioma between males and females, the rates within each had little variance. Those in the oldest age group (over 60) showed the highest incidences of mesothelioma, and the number declined through the younger sets until it became rare in the youngest. It appears that the level of mesothelioma incidence is approaching background levels. Hope for Mesothelioma Sufferers in Treatments? In most cases, the diagnosis of diffuse malignant peritoneal mesothelioma (DMPM) is a death sentence, but survival rates are increasing due to the use of surgical techniques to target the tumors. While both cytoreductive surgery (CRS) along with peri-operative intra-peritoneal chemotherapy (PIC) seem to have benefits in survival, the data from these cases comes from stage I and II trials in a single hospital, leaving much room for other factors. These independent trials can draw no conclusive evidence yet, but as their evidence and methods are scrutinized, better forms of mesothelioma treatment can be developed to give patients hope for survival.
