Second cancers were studied among 68,104 cases of colorectal cancer (CRC) from the Swedish Family-Cancer Database. A total of 1,113 patients received a diagnosis of second CRC; 25 of them had a family history of CRC. Cases of second CRC with a family history were diagnosed up to 10 years before sporadic cases. The relative risk (RR) of all second CRCs was 2.21 compared with the first CRC. Famil...

Patients with lung cancer are at risk of developing a second primary lung cancer (SPLC). However, the characteristics of patients at risk remain largely speculative. We reviewed 2816 lung cancer patients from our institution for the occurrence of SPLC. Any SPLC was categorised as synchronous when diagnosed within 2 years of the first primary lung cancer (FPLC) and after direct histological comp...

BACKGROUND AND AIM There is an increased incidence of secondary primary cancer (SPC) in patients with papillary thyroid carcinoma (PTC). The risk is stronger in the first year after the first malignancy (synchronous tumours). The aim of this study was to assess the prevalence of SPC in patients with PTC, and to analyse whether the timing of tumour presentation influenced the clinicopathological...

Studies of pancreatic cancer in the setting of second primary malignant neoplasms can provide etiologic clues. An international multicenter study was carried out using data from 13 cancer registries with a registration period up to year 2000. Cancer patients were followed up from the initial cancer diagnosis, and the occurrence of second primary malignant neoplasms was compared with expected va...

Ninety-eight women ascertained from high-risk breast/ovarian cancer clinics with breast cancer reporting at least one other primary cancer in themselves or in a relative with breast cancer were compared with 99 women with breast cancer who reported a family history of breast cancer only. All DNA was screened for coding region mutations in BRCA1 and BRCA2 using heteroduplex analysis, followed by...

MATERIALS AND METHODS We analyzed the clinicopathologic data of 214 gastric cancer patients from October 1996 to November 2007 with regard to metachronous second primary cancers. RESULTS Out of 5,778 patients with gastric cancer, metachronous second primary cancers occurre...
