An increasing proportion of new cancers is registered in patients who have received a previous cancer diagnosis. As data are inconsistent across studies, we provided information for populations long covered by valid cancer registration. Data were derived from the Swiss cancer Registries of Vaud and Neuchâtel (885,000 inhabitants). Patients diagnosed with a new malignancy (except skin basal and ...
Scanty data are available on the incidence (i.e., the absolute risk) of second cancers of the head and neck (HN) and its pattern with age. We investigated this issue using data from a multicentric study of 13 population-based cancer registries from Europe, Canada, Australia and Singapore for the years 1943-2000. A total of 99,257 patients had a first primary HN cancer (15,985 tongue, 22,378 mou...
Review of histopathological and clinical data showed that 153 patients at one hospital developed a second primary lung cancer during 1980-6, 10% of all those with lung carcinoma. There were 64 synchronous tumours (interval less than one year) and 89 metachronous tumours (interval over one year). The average interval between metachronous tumours was 6.1 years. The criteria for diagnosing a secon...
Data from the Surveillance, Epidemiology, and End Results (SEER) Program were used to compare the histological distribution of second lung cancer following an initial cancer of the lung, head and neck, and breast to primary lung carcinoma occurring as a first cancer. Following initial head and neck cancer or initial squamous cell carcinoma of the lung, the proportion of second primary lung canc...
BACKGROUND Contralateral second primary breast cancers occur in 4% of female breast cancer survivors. Little is known about differences in risk for second primary breast cancers related to the estrogen and progesterone receptor (hormone receptor [HR]) status of the first tumor. METHODS We calculated standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for contralateral prim...

BACKGROUND The risk of developing a second primary tumour in patients with gastric carcinoma is higher than among the general population. The aim was to investigate the clinicopathological characteristics of the second primary cancers in patients with gastric cancer in this study. PATIENTS AND METHODS In the retrospective study, patients with gastric cancers were evaluated between 1995 and 20...
BACKGROUND Solid organ transplanted patients have a three- to fourfold higher lifetime risk of developing a cancer than the general population. However, the incidence of a second primary cancer in transplanted patients has never been studied, despite the fact that the presence of regular follow-ups and the increased survival of these patients make them a very attractive model. METHODS We inve...
UNLABELLED In the first three years after treatment of patients with squamous cell carcinoma of upper aerodigestive tract (UADT), there is a high incidence of recurrences. After the third year, the occurrence of second primary tumor (SPT) is an important cause of morbimortality. AIM To evaluate the incidence and the characteristics of the SPT in patients with squamous cell carcinoma of UADT, ...
esophageal squamous cell carcinoma is a rather common cancer in northern iran. incidence of adenocarcinoma of esophagus has an increasing trend in iran. co-existence of both cancers in one patient is very rare. we report a middle age woman from northern iran with a typical presentation of esophageal cancer, who was found to have a dual esophageal cancer. the disease was found in the advanced st...
