Clinical analysis of multiple primary malignancies in the elderly

Abstract

Elderly patients are more likely to develop MPM compared to younger ones. Significant cancer association according to field cancerogenesis concept was the one of smoking-related cancer; other MPM patterns were apparently a random phenomenon.

EGFR and KRAS mutations in Chinese patients with adenosquamous carcinoma of the lung

“…The implication of these findings is that geographical differences may also determine different genetic susceptibility in the same race. In addition, this study evaluated the problem of coexistent double cancer with ADSQ, and its prevalence was 9.09%, consistent with previous report of lung cancer [20]. However, Uramoto et al recently reported the proportion with coexistent double cancer of ADSQ was 45.5% [21].…”

Double primary tumor of the stomach and the prostate managed robotically simultaneously

“…Studies based on tumor registries have reported the prevalence to be 1.8-6.4% [1][2][3][4][5] A recent study by Luciani et al [6] covering a three-year period in a single center showed an MPM prevalence of 10% with an mean age of 65. Their results show that it is more common in the elderly.…”

Clinical Features of Patients with Esophageal and Second Primary Cancers

“…Although its incidence was low, accumulating cases with SPC has been diagnosed over the past decades. It was estimated that SPC occurred with the prevalence varying from 0.7% to 11.7% of all cancer patients, depending on different primary cancers (Luciani et al, 2009;Gursel et al, 2011). Additionally, the challenges of SPC to physicians had become of increasing concern because the treatment options to SPC could be limited due to its progression.…”
