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, Prostate cancer and second colorectal cancer also demonstrated a high metachronous association RR, 2. A strong synchronous association was found between uterine and ovarian cancers RR, 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.

In addition, renal pelvis cancer was associated with a high cumulative risk of second primary cancer in men one in six, metachronous.

Synchronous cancer of the colon of a case for more definitive resection in colon cancer. Hepatocellular carcinoma HCC in Taiwan is very common. These two tumors may be diagnosed at the same time synchronous , or the second tumor may be detected 6 months afterwards metachronous. Survival between synchronous and non-synchronous multiple primary cutaneous melanomas-a SEER database analysis. The significance of this study lies in better understanding of types of secondary primary specific cancers and the durations until their occurrence. Abstract The incidence of secondary primary malignancy SPM has been reported to range from 1. However, synchronous secondary or even third primary malignancies increase the difficulty of cancer treatment and decrease patient survival. Cisplatin has been associated with the risk of second cancer. A total of 22, cancer patients were identified over a 5-year period, of whom 0.

Moreover, our results suggested that most of the patients with multiple primary cancers were older at diagnosis of their first cancer than were those diagnosed with a single primary cancer. J Surg Oncol. Table 1 summarizes the risk factors associated with multiple primary malignancies. This review discusses the incidence and risk factors for multiple primary malignancies with a special focus on genitourinary tract primary cancers with synchronous or metachronous primary cancers. Identifying the occurrence of SPM early in the same patient would allow for an earlier diagnosis and treatment, which could improve follow-up care and obtain good survival, so it is an important issue [ 74 ]. A smaller risk is estimated for patients with family history of colorectal cancer
