Metrics details. The situation of patients developing multiple primary cancers is becoming more frequent and graver. This study investigated the risks of developing second primary cancers that are related to first primary cancers, and the interval times of synchronous and metachronous multiple primary cancers. A two-month period between first- and second- primary cancers was used to differentiate metachronous and synchronous multiple primary cancers. The combinations of subsequent cancers and relative risks RRs of having multiple primary cancers versus having single primary cancer for the top-ten first and second primary cancers were examined. The RR was adjusted for age of the first primary cancer. A survival analysis of the time to second-primary-cancer development was performed. Multiple primary cancers were found in 1. Most After adjustment for age at first diagnosis, head and neck cancers had the highest metachronous association with second esophageal cancers RR,

It is well known that hereditary colorectal cancer syndromes, such as familial adenomatous polyposis FAPmetachronous inflammatory bowel disease ulcerative colitis - UC predispose to the development of multiple colorectal carcinomas, metachronous.

The term metachronous is used in oncology to refer to two or more independent primary malignancies, when the second or third, etc. These may be in the same, or in different, organs.

Table 1. Prostate cancer and second colorectal cancer had the second-highest metachronous association RR, 2. Synchronous multiple colorectal adenomas. In two patients with synchronous carcinomas the diagnosis was suspected on barium enema and confirmed with colonoscopy and biopsy. In any other case they are considered as regional spread or metastatic lesions. Those cancers also had a high cumulative incidence at Siriraj Hospital from to Hereditary cancer diseases are associated with many genetic mutations, however, further investigations are needed to clarify which mutations are involved. Urothelial cell carcinoma is prone to local recurrence, distal recurrence, urinary bladder recurrence from upper tract primary malignancy, and contralateral occurrence. The green items represent the top-ten, first-diagnosed cancers of metachronous and synchronous multiple primary cancers for all cases, males, and females. This discrepancy may be due to improvements in radiation treatment. Additionally, female patients with breast cancer had an elevated risk of occurrence of second female genital cancer—uterine RR, 4. In contrast, patients with prostate cancer may develop a second cancer after longer than 2 years. Metachronous colorectal adenocarcinomas.

Although those guidelines may be appropriate for survivors of some cancers, this current finding may incorporate with them to help estimate risk of a subsequent cancer. Tzeng et al. Underlying kidney diseases such as acquired adult polycystic kidney disease have been associated with renal cell carcinoma by increasing DNA damage and repair and decreasing antioxidant capacity [ 70 ]. The top-ten most frequent multiple primary cancers were the following: breast; liver; head and neck; colorectal; male genital cancer—prostate; skin; female genital cancer—uterine; thyroid; lung; and female genital cancer—non-uterine. A strong synchronous association was found between uterine and ovarian cancers RR, The rate of synchronous multiple primary malignancies was Chen M. In this study, we summarize several risk factors related to the occurrence of SPMs and preventive tests, which may help in their early detection and, consequently, better survival. Genitourinary malignancies were reported to be the third-most-common SPM in several reports.
