Cancer Of Omentum

Cancer incidence higher for men than women

The researchers found that mortality rates adjusted for age were higher in men than women for all cancers studied, except the peritoneum, omentum and mesentery. The age-adjusted ratio of male-female mortality rates were higher for cancer of the lip, with 5.51 men died for every woman, followed by larynx (5.37 to 1), the 'hypopharynx (4.47 to 1) and esophagus (4.08 to 1) cancers. Cancer-specific survival was also worse for men in most cancers, but the disparities are not nearly as large.

Michael B. Cook, PhD, an investigator in the division of cancer epidemiology and genetics at the NCI and one of the study's authors, said the results likely reflect that sex disparities in cancer mortality arise from disparities in cancer incidence.

Cook et al used records from the SEER database to calculate cancer mortality counts and rates per 100,000 person-years for each cancer as stratified by sex for the periods 1977-1986, 1987-1996, 1997-2006 and 1977-2006. Sex-specific cancers were excluded, and researchers adjusted for age, year of diagnosis and tumor stage and grade.

Predictably, 5-year OS was poorer for men, although Cook said the differences were not pronounced. Survival was worst for men with basal and squamous cancers (HR=1.58; 95% CI, 1.52-1.64); cancers of the endocrine system (HR=1.32; 95% CI, 1.24-1.42); and cancer of the floor of the mouth (HR=1.32; 95% CI, 1.07-1.63).

Cause-specific mortality in men was lower relative to women for urinary bladder cancer (HR=0.83; 95% CI, 0.81-0.86) and tongue cancer (HR=0.89; 95% CI, 0.83-0.95).

Cook said the next step is to unlock the reasons why incidence is higher in men. The factors driving the disparity in incidence could be biologic, environmental or both, he said.

"Are there some general features about men and women that make men more susceptible and women more protected?" Cook said. "Or is it a question of exposures? Is it that men consume more alcohol, smoke more cigarettes, store their fat in the gut region which is know to be more metabolically active? How do all of these differences play into specific types of cancer?

what is indurated greater omentum consistant with peritoneal ...

I am not a doctor (just been around them alot lately) so I’m not entirely sure. But, my son had stage IV intra-abdominal sarcoma so I’m familiar with some of the words here.

I would suspect that this refers to metastatic spred (tumor implants or seeding) into the abdominal cavity. (the omentum appears hardened indicating ‘seeding’ of tiny nodules or tumors).

You should ask your oncologist though.

Stay strong.
