The Assessment of Second Primary Cancers (SPCs) in a Series of Splenic Marginal Zone Lymphoma (SMZL) Patients

2006

The purpose of this study is to estimate the risk of second primary cancer (SPC) in 129 consecutive patients with splenic marginal zone lymphoma (SMZL) diagnosed in three Italian haematological centres. The person-years method deriving as a sum of products of age- and sex- specific rates and of the corresponding time at risk was used. The SPC Standardized Incidence Ratio (SIR) was 2.03 with a 95% confidence interval: [1.05, 3.56] (p < 0.05) and the corresponding Absolute Excess Risk (AER) was 145.8 (per 10000 SMZL patients per year). Our findings evidence a high frequency of additional cancers in patients with SMZL and suggest that the incidence rate of SPCs is significantly different from …

A population‐based comparison of second primary cancers in G ermany and S weden between 1997 and 2006: clinical implications and etiologic aspects

2013

Second primary cancer (SPC) has become an increasing concern in cancer survivorship. Patterns of SPCs in different populations may offer clinical implications and research priorities into SPCs. This study is devoted to compare the occurrences and rank correlations of SPCs between Germany and Sweden. Patients diagnosed with 10 common first primaries between 1997 and 2006 from the Swedish Family-Cancer Database and 10 German cancer registries were included in this population-based study. Spearman's rank correlation coefficients were used to evaluate the strength of the relationship of SPCs between the German and Swedish datasets. Spearman's rank correlation coefficients suggested a strong pos…

Second primary cancers after cancer of unknown primary in Sweden and Germany: efficacy of the modern work-up.

2012

In unsparing efforts to find the hidden primaries, second primary cancers (SPCs) unrelated to cancer of unknown primary (CUP) are found. The detection rates of SPCs after CUP can be considered as measures for the effectiveness of modern diagnostic techniques in finding tumors. We aimed to compare the rates of specific SPCs found after the work-up of CUP and the more sign/symptom-directed diagnostic approaches applied after any other cancer. The number of CUP patients identified in the nationwide Swedish database and nine German cancer registries was 24 641 from 1997 through 2006, and rate ratios (RRs) for SPCs were recorded in two follow-up periods. The detection rate of SPCs immediately af…
