A Linear Relationship between the Number of Cancers among First-Degree Relatives and the Risk of Multiple Primary Cancers.

With advances in the early detection and treatment of cancer, the incidence of multiple primary cancers (MPC) or second primary cancers has increased over time. Characterization of etiologic risk factors, including family history of cancer, within the general population is critical for assessing MPC risk in patients. We examined the association between family history of cancer among first-degree relatives and MPC risk in a prospective study of 139,958 participants from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Cox proportional hazard models were used to calculate HRs and 95% confidence intervals (95% CI), adjusting for potential confounders. Over a median follow-up of 16 years (IQR: 11-19 years), 6,170 participants were diagnosed with MPC. Having a family history of cancer increased the risk of MPC by 18% (HR, 1.18; 95% CI, 1.12-1.24). A positive linear trend was observed between the reported number of cancers in the family history and MPC risk with HRs (95% CI) of 1.13 (1.07-1.20), 1.23 (1.14-1.33), 1.29 (1.15-1.45), and 1.42 (1.20-1.70) for one, two, three, and four or more cancers among first-degree relatives, respectively (Ptrend = 2.36 × 10-13). No significant differences were observed by cancer histology or specific cancer types reported in the family history. Our study demonstrates that the family history of cancer is an important risk factor for the development of MPCs and that a comprehensive assessment of the number of cancers reported among first-degree relatives may identify those at higher risk who may benefit from targeted cancer prevention and screening strategies. Prevention Relevance: Our study makes a substantial contribution to the understanding of risk factors for MPCs in the general population. It demonstrates that individuals with a strong family history of cancer are at higher risk for MPCs and may benefit from more targeted cancer prevention and screening interventions.

Incidence and Characteristics of Multiple Primary Cancers: A 20-Year Retrospective Study of a Single Cancer Center in Korea.

Rising cancer survival rates have led to an increased risk of multiple primary cancers (MPCs). Data on MPCs in South Korea are limited. This study aimed to address incidence and clinical characteristics of MPCs in a single cancer center in Korea during a 20-year period. We retrospectively analyzed 96,174 cancer patients at the Korea Cancer Center Hospital between 2003 and 2022, identifying 2167 patients with metachronous MPCs based on Surveillance, Epidemiology, and End Results SEER criteria. We categorized patients by cancer type (15 major solid cancer groups and 3 major hematologic cancer groups), including pathological diagnosis, assessed latency periods, and relative risks (RRs) for developing MPCs. The overall MPC incidence was 2.3%. Breast cancer (15.7%) was the most common primary cancer, and lung cancer (15.2%) was the most frequent second primary cancer. The median latency period for second primary cancers was 4.1 years. Decreasing latency periods for third and fourth primary cancers were observed (2.1 years and 1.6 years, respectively). Most cancers maintained their dominant pathological type despite notable changes in the prevalence of specific pathologies for certain types of second primaries. Lymphoma showed the highest RR (2.1) for developing MPCs. Significant associations were found between specific primary and subsequent cancers, including breast-ovary, thyroid-breast, stomach-pancreas, colorectal-head and neck, lung-prostate, and lymphoma-myeloid neoplasms. These findings contribute to a better understanding of MPC occurrence. They can inform future research on their etiology and development of improved management strategies.

Abstract 6147: Genome-wide association study identifies new genetic susceptibility loci for multiple primary cancers

Abstract Objectives: Genetic susceptibility is thought to contribute to the development of multiple primary cancers (MPC), often called secondary cancers. Although rare variants contribute to risk, these only account for a small fraction of MPC cases. The contribution of common variants to risk is unknown. Methods: To identify common genetic variants associated with the risk of MPC, we conducted a trans-ancestry meta-analysis of genome-wide association studies (GWAS), including 7,360 MPC cases and 138,684 controls from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial and UK Biobank (UKBB). Association analyses were performed separately by genetic ancestry, genotype platform, and study, adjusting for age, sex, and principal components, and the results were meta-analyzed together using a fixed effects model. Genome-wide SNP heritability was estimated using GCTA. Pathway and functional enrichment analyses were conducted to gain insights into potential biological mechanisms underlying discovered loci. Results: We identified one novel locus at chromosome 3q26.2 (LRRC34, rs7621631) that was associated with MPC risk (P=1.16x10-8). Variants in this region have been previously associated with telomere length, suggesting a possible underlying mechanism. In sex-stratified analyses, we identified an additional locus at chromosome 12q24.33 (intergenic, rs10466868) associated with MPC in men (P= 7.76x10-8), but not women. Although the risk associated with these two discovered loci was small, the genome-wide SNP heritability was estimated to be 12%, suggesting that there are likely more common variants to be discovered for MPC risk. Conclusions: Our study demonstrates that common genetic variation contributes to the risk of multiple primary cancers and suggests additional loci are likely to be identified with larger studies.

Penetrance Estimates Over Time to First and Second Primary Cancer Diagnosis in Families with Li-Fraumeni Syndrome: A Single Institution Perspective.

Li-Fraumeni syndrome (LFS) is a rare autosomal dominant disorder associated with TP53 germline mutations and an increased lifetime risk of multiple primary cancers (MPC). Penetrance estimation of time to first and second primary cancer within LFS remains challenging because of limited data and the difficulty of characterizing the effects of a primary cancer on the penetrance of a second primary cancer. Using a recurrent events survival modeling approach that incorporates a family-wise likelihood to efficiently integrate the pedigree structure, we estimated the penetrance for both first and second primary cancer diagnosis from a pediatric sarcoma cohort at MD Anderson Cancer Center [MDACC, Houston, TX; number of families = 189; single primary cancer (SPC) = 771; and MPC = 87]. Validation of the risk prediction performance was performed using an independent MDACC clinical cohort of TP53 tested individuals (SPC = 102 and MPC = 58). These findings showed that an individual diagnosed at a later age was more likely to be diagnosed with a second primary cancer. In addition, TP53 mutation carriers had a HR of 1.65 (95% confidence interval, 1.1-2.5) for developing a second primary cancer versus SPC. The area under the ROC (AUC) curve for predicting individual outcomes of MPC versus SPC was 0.77. In summary, we provide the first set of penetrance estimates for first and second primary cancer for TP53 germline mutation carriers and demonstrate its accuracy for cancer risk assessment. SIGNIFICANCE: These findings present an open-source R package LFSPRO that could be used for genetic counseling and health management of individuals with LFS as it estimates the risk of both first and second primary cancer diagnosis.See related article by Shin et al., p. 354.

Multiple primary malignancies for squamous cell carcinoma and adenocarcinoma of the esophagus.

Patients with esophageal cancer (EC) frequently have multiple primary cancers. We conducted the present study to assess the risk of multiple primary malignancies for patients with squamous cell carcinoma (SCC) and adenocarcinoma (AC) of the esophagus and to investigate the influence of multiple primary tumors on the prognosis of EC patients. Using the data of 44,091 EC patients from the Surveillance Epidemiology and End Results (SEER) database, we calculated the standardized incidence ratios (SIRs) for overall multiple primary cancers and cancers at particular sites among EC survivors. The SIRs of esophageal SCC and AC patients were compared using Poisson regression. The Kaplan-Meier (KM) method was used for survival analysis. Multiple primary cancer risk was significantly increased among both esophageal SCC and AC survivors (SIR: 2.28 and 1.57, respectively; P<0.001). Among SCC patients, the highest SIRs were found in the oral cavity and pharynx (SIR: 16.54), esophagus (SIR: 10.02), and larynx (SIR: 10.34). Also, the highest SIRs following AC cases were observed in the esophagus (SIR: 8.81), stomach (SIR: 9.29), and small intestine (SIR: 4.95). SIRs for the oral cavity and pharynx, lung, and larynx were significantly higher among SCC survivors than AC survivors (all P<0.05). KM analysis revealed no significant difference of overall survival (OS) for multiple primary cancers, including those of the esophagus, stomach, oral cavity and pharynx, and lung among EC patients (log rank =2.04; P=0.564), except for prostate cancer (log rank =96.65; P<0.001). Multiple primary malignancy risk differed by the histological type of esophageal SSC and AC survivor. However, no significant relationship between survival and the multiple primary cancer sites, except for prostate cancer, was observed.

Association between Mismatch-repair Genetic variation and the Risk of Multiple Primary Cancers: A Meta-Analysis.

Microsatellites instability (MSI) is a risk factor for multiple primary cancers (MPCs). However, a variety of studies focused on the risk in the hereditary non-polyposis colorectal cancer (HNPCC) not the sporadic colorectal cancer (CRC) patients. The aim of this meta-analysis was to comprehensive overview and quantitative summary the association between MSI and risk of MPCs. A comprehensive literature search in MEDLINE, EMBASE, Web of science, ScienceDirect, Weily and OVID was conducted. Up to May 2016, we identified 22 observational studies. We calculated the summary relative risk (RR) for the risk of MPCs in MSI patients compared with microsatellites stability (MSS) patients using fixed- or random-effects models. The RR of the association between mismatch-repair gene (MMR) genotype and MPCs was 2.59 (95% confidence interval [CI], 2.06 to 3.27); the RR was 2.14 (95% CI, 1.78 to 2.57) for sporadic CRC and 5.59 (95% CI, 2.69 to 11.59) for HNPCC for the MSI versus MSS category. The subgroup analyses showed different mutant gene, mutant locus, and mutant level of MMR with different influence on the patients susceptible to MPCs. In addition, MSI genotype increase the risk of MPC was not associated with an apparently specific in regard to site, timing, age and detection method. In conclusion, this meta-analysis indicates that MSI is associated with an increased risk of MPCs both in the HNPCC and sporadic CRC patients. Our findings will form the backbone of the treatment for MSI genotype may be an important valuable strategy for MPCs prevention.

Changing roles of population-based cancer registries in Australia.

Registries have key roles in cancer incidence, mortality and survival monitoring and in showing disparities across the population. Incidence monitoring began in New South Wales in 1972 and other jurisdictions soon followed. Registry data are used to evaluate outcomes of preventive, screening, treatment and support services. They have shown decreases in cancer incidence following interventions and have been used for workforce and other infrastructure planning. Crude markers of optimal radiotherapy and chemotherapy exist and registry data are used to show shortfalls against these markers. The data are also used to investigate cancer clusters and environmental concerns. Survival data are used to assess service performance and interval cancer data are used in screening accreditation. Registries enable determination of risk of multiple primary cancers. Clinical quality registries are used for clinical quality improvement. Population-based cancer registries and linked administrative data complement clinical registries by providing high-level system-wide data. The USA Commission on Cancer has long used registries for quality assurance and service accreditation. Increasingly population-based registry data in Australia are linked with administrative data on service delivery to assess system performance. Addition oftumour stage and otherprognostic indicators is important forthese analyses and is facilitated by the roll-out of structured pathology reporting. Data linkage with administrative data, following checks on the quality of these data, enables assessment of patterns of care and other performance indicators for health-system monitoring. Australian cancer registries have evolved and increasingly are contributing to broader information networks for health system management.

Association of cancer susceptibility variants with risk of multiple primary cancers: The population architecture using genomics and epidemiology study.

Multiple primary cancers account for approximately 16% of all incident cancers in the United States. Although genome-wide association studies (GWAS) have identified many common genetic variants associated with various cancer sites, no study has examined the association of these genetic variants with risk of multiple primary cancers (MPC). As part of the National Human Genome Research Institute (NHGRI) Population Architecture using Genomics and Epidemiology (PAGE) study, we used data from the Multiethnic Cohort (MEC) and Women's Health Initiative (WHI). Incident MPC (IMPC) cases (n = 1,385) were defined as participants diagnosed with more than one incident cancer after cohort entry. Participants diagnosed with only one incident cancer after cohort entry with follow-up equal to or longer than IMPC cases served as controls (single-index cancer controls; n = 9,626). Fixed-effects meta-analyses of unconditional logistic regression analyses were used to evaluate the associations between 188 cancer risk variants and IMPC risk. To account for multiple comparisons, we used the false-positive report probability (FPRP) to determine statistical significance. A nicotine dependence-associated and lung cancer variant, CHRNA3 rs578776 [OR, 1.16; 95% confidence interval (CI), 1.05-1.26; P = 0.004], and two breast cancer variants, EMBP1 rs11249433 and TOX3 rs3803662 (OR, 1.16; 95% CI, 1.04-1.28; P = 0.005 and OR, 1.13; 95% CI, 1.03-1.23; P = 0.006), were significantly associated with risk of IMPC. The associations for rs578776 and rs11249433 remained (P < 0.05) after removing subjects who had lung or breast cancers, respectively (P ≤ 0.046). These associations did not show significant heterogeneity by smoking status (Pheterogeneity ≥ 0.53). Our study has identified rs578776 and rs11249433 as risk variants for IMPC. These findings may help to identify genetic regions associated with IMPC risk.

Multiple primary cancers among colorectal cancer survivors in Queensland, Australia, 1996–2007

To quantify the demographic and clinical factors associated with an increased risk of multiple primary cancers (MPCs) among colorectal cancer survivors. Standardized incidence ratios for MPCs were calculated for residents of Queensland, Australia, who were diagnosed with a first primary colorectal cancer between 1996 and 2005 and survived for at least 2months. Relative risk ratios were calculated for all MPCs combined and selected individual sites using multivariate Poisson models. A total of 1,615 MPCs were observed among 15,755 study patients. The cohort had a significant excess risk of developing subsequent colorectal (SIR=1.47, 95% CI 1.30-1.66) or non-colorectal (SIR=1.24, 95% CI 1.18-1.31) cancers relative to the incidence of cancer in the general population. Age at initial diagnosis, follow-up time, initial colorectal subsite, and surgical treatment were independently associated (p<0.01) with the overall risk of developing MPCs after adjustment. The relative risk ratio was 1.23 (95% CI 1.07-1.41) for those aged 20-59years compared with the 70-79 age group and 0.82 (95% CI 0.72-0.92) for 1-5-year follow-up relative to the first year. The likelihood of being diagnosed with a MPC was 33% higher (95% CI 1.12-1.56) for surgically treated patients and 45% higher (95% CI 1.29-1.64) after proximal colon cancers relative to rectal cancer. While these population-based results do not incorporate all possible risk factors, they form an important foundation from which to further investigate the etiological causes that result in the development of MPCs among colorectal cancer survivors.

Risk of multiple primary cancers following melanoma and non‐melanoma skin cancer

The relationship between cutaneous malignancies and successive primary cancers has been studied since several years, but it still remains controversial. The aim of this study was to evaluate the excess risk of multiple primary cancer among the population of Umbria, Italy, that survived a skin cancer. The data registered in the Umbrian Population Cancer Registry from 1994 to 2006 were collected, recorded, and analysed in accordance to the standard methods recommended for cancer registries. Among skin cancer patients, those with multiple cutaneous and non-cutaneous cancers were selected. Only sites with a frequency of more than five cases were considered. The expected number of cases was obtained from indirect standardization with regional incidence rates in several sites that incurred in the overall period. The significance of the observed/expected ratios and the corresponding 95% CI were based on the Poisson distribution. In men, a significant standardized incidence ratio (SIR) was found for melanoma (2.21), non-melanoma skin cancers (1.86), Hodgkin's (4.95) and non-Hodgkin lymphoma (1.82), and tongue/mouth cancer (2.47). In women, melanoma, non-melanoma skin and breast cancer showed a significant high SIRs (4.13, 1.55 and 1.28 respectively). All other cancers showed a non-significant SIR. Considering all sites combined and all sites except skin cancers, the analysis showed a significant excess in men, whereas a significant risk was observed in women only when also skin cancers were considered. Data from the whole of Umbrian population revealed that skin cancer patients experience marked excess risk of further primary cancers. The main risk in both genders is skin melanoma and other skin cancers. The excess of lymphomas and tongue/mouth cancers is also significant in men, and breast cancer in women. These observations prompt us to include a screening for these cancers in the follow-up of our patients surviving a skin malignancy.

Relationship between Radiation Exposure and Risk of Second Primary Cancers among Atomic Bomb Survivors

Radiation exposure is related to risk of numerous types of cancer, but relatively little is known about its effect on risk of multiple primary cancers. Using follow-up data through 2002 from 77,752 Japanese atomic bomb survivors, we identified 14,048 participants diagnosed with a first primary cancer, of whom 1,088 were diagnosed with a second primary cancer. Relationships between radiation exposure and risks of first and second primary cancers were quantified using Poisson regression. There was a similar linear dose-response relationship between radiation exposure and risks of both first and second primary solid tumors [excess relative risk (ERR)/Gy = 0.65; 95% confidence interval (CI), 0.57-0.74 and ERR/Gy = 0.56; 95% CI, 0.33-0.80, respectively] and risk of both first and second primary leukemias (ERR/Gy = 2.65; 95% CI, 1.78-3.78 and ERR/Gy = 3.65; 95% CI, 0.96-10.70, respectively). Background incidence rates were higher for second solid cancers, compared with first solid cancers, until about age 70 years for men and 80 years for women (P < 0.0001), but radiation-related ERRs did not differ between first and second primary solid cancers (P = 0.70). Radiation dose was most strongly related to risk of solid tumors that are radiation-sensitive including second primary lung, colon, female breast, thyroid, and bladder cancers. Radiation exposure confers equally high relative risks of second primary cancers as first primary cancers. Radiation is a potent carcinogen and those with substantial exposures who are diagnosed with a first primary cancer should be carefully screened for second primary cancers, particularly for cancers that are radiation-sensitive.

Genetic screening for multiple endocrine neoplasia syndrome type 1 (MEN-1): when and how

Multiple endocrine neoplasia syndrome type 1 (MEN1) syndrome has benefited from the identification of the gene whose mutations account for the genetic susceptibility to develop endocrine tumors. Asymptomatic MEN1 mutant carriers need to be clearly recognized because the gene-related mutations confer a high risk of multiple primary cancers, occur at younger ages, and affect multiple family members who inherit the cancer-predisposing genetic mutation.

Bladder Cancer Incidence and Risk Factors in Men With Prostate Cancer: Results From Cancer of the Prostate Strategic Urologic Research Endeavor

We evaluated a large disease registry to determine the incidence of bladder cancer in patients with prostate cancer and investigate whether the type of treatment for prostate cancer increased the risk of bladder cancer. We analyzed the CaPSURE disease registry for men diagnosed with prostate cancer plus bladder cancer between 1989 and 2003. Demographics, comorbidities and prostate cancer treatment modalities were compared in patients with and without bladder cancer. A backward stepwise Cox proportional hazards regression model was used to predict bladder cancer onset after treatment for prostate cancer in patients who had bladder cancer 30 days or greater after prostate cancer treatment. Of 9,780 patients from CaPSURE 143 (1.46%) also had bladder cancer. Patients with bladder cancer and prostate cancer were older (p<0.01) and more likely to be white (p=0.03), and they had lower levels of income (p<0.01) and education (p=0.04) than patients with prostate cancer only. Comorbidities did not differ between patients with and without bladder cancer. Patients treated with radical prostatectomy were approximately half as likely to have posttreatment bladder cancer as patients who underwent radiation therapy (HR 0.51, 95% CI 0.29-0.89). Patients who smoked had an independent increase in the risk of bladder cancer (HR 2.08, 95% CI 1.09-3.97), while smokers treated with radiation therapy were at almost 4-fold risk for bladder cancer (HR 3.65, 95% CI 1.45-9.16). The incidence of bladder cancer in patients with prostate cancer was 1.5%. Radiation therapy and smoking increased the risk of bladder cancer.

Obtaining smoking histories for population‐based studies on multiple primary cancers: Connecticut, 2002

Because of the absence of data on smoking history for patients in cancer registries, large population-based studies have been unable to directly assess the role of smoking in the risk of multiple primary cancers. In a random sample of 618 adults diagnosed with invasive cancer in 2002 and reported to the population-based Connecticut (CT) cancer registry, however, search of hospital records identified smoking history (current, former, never- or nonsmoker) for 83.3%. Number of cigarettes per day was known for 71.3% of 289 current or former smokers, while duration of quitting was found for 92.3% of 194 former smokers. Smoking status was strongly associated with current heavy alcohol use. Hospital records appear to be a promising resource for population-based studies on smoking histories in relation to risk of multiple primaries, although completeness of information needs to be improved in CT and assessments are needed in other cancer registries.

Risk of multiple primary cancers in prostate cancer patients in the Detroit metropolitan area: a retrospective cohort study.

Patterns of excess risk for second primary cancers (SPC) in prostate cancer patients have been observed for urinary bladder, other sites in the urinary tract, and hematolymphopoietic tissues in several, but not all, previously reported cohort studies. The risk of SPC was evaluated in 9,794 Detroit metropolitan-area men originally diagnosed with carcinoma of the prostate during 1973-1982. The cohort was assembled using Detroit Surveillance, Epidemiology, and End Results (SEER) Registry data and followed until December 31, 1993. The observed number of SPC of all sites was similar to the expected number in the cohort. A significant excess of invasive SPC of the urinary bladder [Standardized incidence ratio (SIR) = 1.57; 95% CI, 1.34-1.83] was observed in this cohort, but after excluding the first 2 months after prostate cancer diagnosis, the excess (SIR = 1.06) was no longer statistically significant. The cumulative proportion of patients with prostate cancer who developed bladder cancer during a follow-up interval of 20 years was 5.5% (95% CI, 4.1-6.9%). The patients who received first-course radiation treatment were observed to be at increased risk for bladder SPC (all stages; SIR = 1.49; 95% CI, 1.07-2.02) when compared to the Detroit-area male population. These results underscore the importance of continuing medical surveillance for urinary bladder second primary cancers in patients with prostate cancer, but are reassuring in that the magnitude of relative and absolute risks does not suggest deterring adverse effects of radiation treatment or intrinsic risks for neoplasms in other organs or tissues.
