Data from the Cancer Registries of the Swiss Cantons of Vaud and Neuchâtel were analysed to examine possible associations between skin cancers (including basal cell carcinoma, BCC), non-Hodgkin''s lymphomas (NHL) and chronic lymphocytic leukaemias (CLL). Between 1974 and 1993, 1767 cases of NHL, 351 of CLL, 1678 of cutaneous malignant melanoma (CMM), 4131 of squamous cell carcinoma (SCC) and 10575 of BCC were registered, and contributed to a total of 120103 person-years at risk. Following NHL, 36 cases of SCC were registered compared with 5.1 expected, corresponding to a standardised incidence ratio (SIR) of 7.0 (95% confidence interval, CI, 4.9-9.7); 37 cases of BCC were observed compared with 10.2 expected (SIR = 3.6; 95% CI 2.6-5.0). Following CLL, nine cases of SCC were observed compared with 1.8 expected (SIR = 5.0; 95% CI 2.3-9.5) and nine cases of BCC were observed compared with 3.3 expected (SIR = 2.7; 95% CI 1.2-5.2). After SCC, 23 cases at NHL were observed compared with 9.0 expected (SIR = 2.6; 95% CI 1.6-3.8); after BCC, 43 cases of NHL were registered compared with 22.5 expected (SIR = 1.9; 95% CI 1.4-2.6); and after CMM, four cases of NHL were observed compared with 2.0 expected (SIR = 2.0). No significant excess of CLL was recorded following skin cancer, but the absolute numbers were small and the SIR was above unity. The findings of this study, conducted in populations with a high level of ascertainment and registration of skin cancers, confirm an excess of skin cancers including BCC, following NHL and CLL, and an excess of NHL following skin cancers. This may be related to shared aetiological factors such as U.V. radiation and associated immunosuppression. Individual-based data on the relationship between U.V. exposure and lymphoid neoplasms are needed to clarify the issue. 相似文献

The purpose of this study was to quantify the risk of cancers other than melanoma among family members of CDKN2A mutation carriers using data from the Genes, Environment and Melanoma study. Relative risks (RRs) of all non-melanoma cancers among first-degree relatives (FDRs) of melanoma patients with CDKN2A mutations (n = 65) and FDRs of melanoma patients without mutations (n = 3537) were calculated as the ratio of estimated event rates (number of cancers/total person-years) in FDRs of carriers vs noncarriers with exact Clopper-Pearson-type tests and 95% confidence intervals (CIs). All statistical tests were two-sided. There were 56 (13.1%) non-melanoma cancers reported among 429 FDRs of mutation carriers and 2199 (9.4%) non-melanoma cancers in 23?452 FDRs of noncarriers. The FDRs of carriers had an increased risk of any cancer other than melanoma (56 cancers among 429 FDRs of carrier probands vs 2199 cancers among 23?452 FDRs of noncarrier probands; RR = 1.5, 95% CI = 1.2 to 2.0, P = .005), gastrointestinal cancer (20 cancers among 429 FDRs of carrier probands vs 506 cancers among 23?452 FDRs of noncarrier probands; RR = 2.4, 95% CI = 1.4 to 3.7, P = .001), and pancreatic cancer (five cancers among 429 FDRs of carrier probands vs 41 cancers among 23?452 FDRs of noncarrier probands; RR = 7.4, 95% CI = 2.3 to 18.7, P = .002). Wilms tumor was reported in two FDRs of carrier probands and three FDRs of noncarrier probands (RR = 40.4, 95% CI = 3.4 to 352.7, P = .005). The lifetime risk of any cancer other than melanoma among CDKN2A mutation carriers was estimated as 59.0% by age 85 years (95% CI = 39.0% to 75.4%) by the kin-cohort method, under the standard assumptions of Mendelian genetics on the genotype distribution of FDRs conditional on proband genotype. 相似文献

BACKGROUND: Orthopedic implants and their fixatives contain materials with carcinogenic potential. Whether these implants are linked to subsequent cancer development remains unknown, mainly because large-scale, long-term follow-up data are scarce. METHODS: We conducted a nationwide cohort study in Sweden to examine cancer incidence among 116,727 patients who underwent hip replacement surgery during the period from 1965 through 1994. Through record linkage to the Swedish Cancer Register, we identified all incident cancers through 1995 in this population (693,954 person-years of observation). For each cancer type, the observed number of cases was divided by that expected in the general Swedish population to produce standardized incidence ratios (SIRs). RESULTS: Relative to the general population, the cohort had no overall cancer excess (SIR = 1.01; 95% confidence interval [CI] = 0.99 to 1.03). However, we observed elevated SIRs for prostate cancer (SIR = 1.16; 95% CI = 1.11 to 1.22) and melanoma (SIR = 1.15; 95% CI = 1.01 to 1.30) and a reduction in stomach cancer risk (SIR = 0.83; 95% CI = 0.75 to 0.92). Long-term follow-up (>or=15 years) revealed an excess of multiple myeloma (SIR = 1.86; 95% CI = 1.01 to 3.11) and a statistically nonsignificant increase in bladder cancer (SIR = 1.42; 95% CI = 0.98 to 1.99). There was no material increase in risk for bone or connective tissue cancer for either men or women in any follow-up period. CONCLUSIONS: In this, the largest study to date, hip implant patients had similar rates of most types of cancer to those in the general population. Although the excesses of melanoma, multiple myeloma, and prostate and bladder cancers may be due to chance, confounding, or detection bias and should be interpreted cautiously, they warrant further investigation because of the ever-increasing use of hip implants at younger ages. 相似文献

Purpose
Persistent cervical infection with human papillomavirus (HPV) may be a marker of poor immune function and thus associated with an increased cancer risk. HPV infection is implicated in all cases of cervical cancer, but except for anal and esophageal cancers, the association between persistent HPV infection and gastrointestinal cancer has not been investigated.Methods
We performed a nationwide population-based cohort study of 83,008 women undergoing cervical conization between 1978 and 2011, using cervical conization as a marker of chronic HPV infection. We computed standardized incidence ratios (SIRs) as a measure of the relative risk of each cancer comparing women undergoing conization with that expected in the general population. We also calculated absolute risks.Results
During follow-up, 988 GI cancers occurred versus 880 expected among 83,008 women followed for a median of 14.9 years, corresponding to a SIR of 1.1 (95 % CI 1.1–1.2). Risks were increased for anal (SIR 2.9; 95 % CI 2.3–3.5) and esophageal (SIR 1.5; 95 % CI 1.1–2.0) cancers, with suggested increased risks of cancers of the gallbladder and biliary tract (SIR 1.3; 95 % CI 0.90–1.8), pancreas (SIR 1.2; 95 % CI 0.97–1.4), and liver (SIR 1.1; 95 % CI 0.79–1.6). The SIRs decreased with increasing follow-up time. The risks of gastric, small intestinal, colon, or rectal cancers were not elevated. Overall, the absolute cancer risk was 0.18 % (95 % CI 0.15–0.21) after 5 years.Conclusions
The relative risks of several gastrointestinal cancers were raised among women who underwent cervical conization for persistent HPV infection, but the absolute risks were low. 相似文献5.
The relative risk of subsequent cancers was evaluated for a total of 9,092 patients with lip and oropharyngeal cancer recorded between 1953 and 1989 in the nationwide Finnish Cancer Registry. The observed numbers of patients were compared with those expected on the basis of the incidence rates in the Finnish population. There were 1,130 patients (12%) with a new cancer. The standardised incidence ratio (SIR) of contracting a new primary cancer was 1.2 for lip cancer patients (95% CI 1.1-1.3) and 1.4 for patients with oropharyngeal cancer (95% CI 1.2-1.4). Among lip cancer patients, a statistically significant excess risk was found for subsequent cancers in the oropharyngeal area (SIR 1.9, 95% CI 1.1-3.1), larynx (SIR 2.0, 95% CI 1.2-2.9) and lung (SIR 1.4, 95% CI 1.3-1.6), i.e. for cancers with tobacco aetiology. Among patients with oropharyngeal cancer there was an excess of lip cancer (SIR, 3.5, 95% CI 1.5-6.9), lung cancer (SIR 1.8, 95% CI 1.3-2.3) and leukaemia (SIR 2.3, 95% CI 1.0-4.3). Radiotherapy for the first primary did not increase the risk of new cancer. 相似文献

BACKGROUND: Workers exposed to low doses of radiation can provide information regarding cancer risks that are of public concern. However, characterizing risk at low doses requires large populations and ideally should include a large proportion of women, both of which rarely are available. METHODS: Among 90305 radiologic technologists in the U.S. (77% women) who were followed during 1983-1998, data concerning incident cancer occurrence was obtained from mailed questionnaires and from death records. Standardized incidence ratios (SIRs) were computed using age-specific, gender-specific, race-specific, and calendar year-specific cancer rates from the Surveillance, Epidemiology, and End Results Program. RESULTS: The SIR for all cancers in both genders combined was 1.04 (95% confidence interval [95% CI], 1.00-1.07; n = 3292 technologists). Female technologists had an elevated risk for all solid tumors combined (SIR = 1.06; 95% CI, 1.02-1.10; n = 2168 women) and for breast cancers (SIR = 1.16; 95% CI, 1.09-1.23; n = 970 women), melanoma (SIR = 1.66; 95% CI, 1.43-1.89; n = 181 women), and thyroid cancers (SIR = 1.54; 95% CI, 1.24-1.83; n = 107 women). Male technologists experienced a decreased risk for solid tumors (SIR = 0.92; 95% CI, 0.85-0.98; n = 755 men); however, melanoma (SIR = 1.39; 95% CI, 1.00-1.79; n = 56 men) and thyroid cancers (SIR = 2.23; 95% CI, 1.29-3.59; n = 17 men) were increased. Among both genders, the risks were decreased for buccal cavity/pharyngeal cancers (SIR = 0.73; 95% CI, 0.55-0.90; n = 54 technologists), rectal cancers (SIR = 0.62; 95% CI 0.48-0.76; n = 53 technologists), and lung cancers (SIR = 0.77, 95% CI, 0.70-0.85; n = 307 technologists). CONCLUSIONS: The elevated risk for breast cancer may have been related to occupational radiation exposure. The observed excesses of melanoma and thyroid cancers may reflect, at least in part, earlier detection among medical workers with easy access to health care. 相似文献

We calculated the short-term and long-term risks of developing cancer among 3,766 patients with a diagnosis of cutaneous melanoma in situ in Sweden from 1958 to 1992. In total, 393 patients developed a primary cancer at any site compared with an expected number of 177 [standardized incidence ratio (SIR) = 2.2, 95% confidence interval (CI) = 2.0-2.4]. Patients below 60 years of age at diagnosis had the highest SIR (2.7, 95% CI = 2.3-3.2). The overall risks were similar between men and women. The highest risk was seen during the first year of follow-up, though the risk remained elevated also after 15 or more years of follow-up. For specific sites, the highest SIR was found for developing invasive cutaneous malignant melanoma (SIR = 22.2). The risk of subsequent primary non-melanoma skin cancer was elevated 8-fold in men and almost 7-fold in women. An elevated risk was also found for female breast cancer (SIR = 1.4). Especially among women, other sites with increased cancer risk (though not significant) were non-Hodgkin's lymphoma (SIR = 1.9), multiple myeloma (3.2) and cancers of the colon (1.6) and pancreas (1.6). In conclusion, patients with melanoma in situ run a generally increased risk of developing primary cancers, especially cutaneous malignant melanoma and non-melanoma skin cancer. The increased long-term risk of cancer after diagnosis of melanoma in situ may be due to continuing carcinogenic exposure or to intrinsic tumor susceptibility. 相似文献

BACKGROUND: Previous studies have been inconclusive in estimating the risk of different cancer sites among close relatives of glioma patients; however, malignant melanoma has consistently been described. METHODS: We obtained family history information from 1,476 glioma patients under age 75 years who registered at M. D. Anderson Cancer Center between June 1992 and June 2006. The number of observed cancers (N=1,001) among 8,746 first-degree relatives (FDR) was compared with the number expected from age-, sex-, and calendar year-specific rates from the Surveillance, Epidemiology, and End Results Program using standardized incidence ratios (SIR). RESULTS: The overall SIR for any cancer was 1.21 (95% confidence interval, 1.14-1.29). Among FDRs under 45 years the overall SIR was 5.08, and for relatives >45 years the overall SIR was 0.95. The SIRs were significantly elevated for brain tumors (2.14), melanoma (2.02), and sarcoma (3.83). We observed an excess of pancreatic cancer, which was significantly higher only among mothers. CONCLUSION: We observed an overall 21% increase in cancer among the FDRs of glioma patients including excess cases of brain tumors and melanoma, which could point to similar genetic contributions to these two malignancies. A large international linkage study is under way to examine potential genomic regions important for familial glioma. 相似文献

Ultraviolet radiation is the major cause of skin cancer, but promotes vitamin D synthesis, and vitamin D has been inversely related to the risk of several common cancers including prostate, breast and colorectum. We therefore computed the incidence of prostate, breast and colorectal cancer following skin cancer using the datasets of the Swiss cancer Registries of Vaud and Neuchatel. Between 1974 and 2005, 6,985 histologically confirmed squamous cell skin cancers, 21,046 basal cell carcinomas and 3,346 cutaneous malignant melanomas were registered, and followed up to the end of 2005 for the occurrence of second primary cancer of the prostate, breast and colorectum. Overall, 680 prostate cancers were observed versus 568.3 expected (standardized incidence ratio (SIR) = 1.20; 95% confidence interval (CI): 1.11-1.29), 440 breast cancers were observed versus 371.5 expected (SIR = 1.18; 95% CI: 1.08-1.30) and 535 colorectal cancers were observed versus 464.6 expected (SIR = 1.15; 95% CI: 1.06-1.25). When basal cell, squamous cell and skin melanoma were considered separately, all the SIRs for prostate, breast and colorectal cancers were around or slightly above unity. Likewise, the results were consistent across strata of age at skin cancer diagnosis and location (head and neck versus others), and for male and female colorectal cancers. These findings, based on a population with a long tradition of systematic histologic examination of all surgically treated skin lesions, do not support the hypothesis that prostate, breast and colorectal cancer risk is decreased following skin cancer. 相似文献

Purpose
In vitro and animal models suggest that the physiological effects of sleep apnea could contribute to cancer risk, yet epidemiologic studies have been inconsistent.Methods
We identified a cohort of adults diagnosed with sleep apnea between 2005 and 2014 using regional administrative databases. Linking this cohort to a population-based cancer registry, we identified first incident cancers diagnosed after sleep apnea diagnosis through 2015. We calculated age–sex standardized cancer incidence ratios (SIRs) to compare the observed number of cancers among those with sleep apnea with expected population estimates over a comparable period.Results
Among 34,402 individuals with sleep apnea, 1,575 first incident cancers were diagnosed during follow-up (mean?±?SD; 5.3?±?2.0 years). Compared to the general population, cancer incidence (SIR 1.26, 95% CI 1.20–1.32) was elevated among sleep apnea patients. We observed significantly elevated incidence for kidney (SIR 2.24, 95% CI 1.82–2.72), melanoma (SIR 1.71, 95% CI 1.42–2.03), breast (SIR 1.43, 95% CI 1.76–2.00), and corpus uteri (SIR 2.80, 95% CI 2.24–2.47) while risk for lung (SIR 0.66, 95% CI 0.54–0.79) and colorectal cancer (SIR 0.71, 95% CI 0.56–0.89) was lower.Conclusion
These findings suggest an elevated cancer burden, particularly at certain sites, among individuals with diagnosed sleep apnea. Results should be interpreted with caution due to unmeasured confounders (e.g., BMI, diabetes).11.

Incidence of subsequent malignant tumor development in 740 patients with primary cutaneous melanoma verified between 2006 and 2010 at the Semmelweis University was studied retrospectively and was compared to data of sex and age matched Hungarian population. The follow-up period was 1499 person-years for the whole group from the diagnosis of index melanoma with an average of 2 years. Standardized incidence rate (SIR) was established as the ratio of observed and expected values. The risk of all subsequent malignancies was 15- and 10-fold higher in males (SIR: 15.42) and in females (SIR: 10.55) with melanoma, than in the general population. The increased cancer risk resulted mainly from the significantly higher skin tumor development: SIR values were 160.39 and 92.64 for additional invasive melanoma and 342.28 and 77.04 for subsequent in situ melanoma in males and females, respectively. Non-melanoma skin cancers also notably contributed to the higher risk, the SIR was elevated in both genders to the same extent (males: 17.12, females: 17.55). The risk was also significantly higher for extracutaneous tumor development like chronic lymphocytic leukemia, colon and kidney cancer (both genders), non-Hodgkin’s lymphoma, cervical cancer (females), and bladder carcinoma (males). These data underline the importance of patient education and the necessity of frequent medical follow up, including a close-up dermatological screening of melanoma survivors for further malignancies. 相似文献

Risk of malignancy among patients with rheumatic conditions 总被引:10,自引:0,他引:10

Previous studies have described an increased risk of malignancy in subjects diagnosed with rheumatic conditions, most notably rheumatoid arthritis (RA). Our aim was to quantify and compare risks for site-specific malignancy among hospitalized patients with RA, osteoarthritis (OA) and other rheumatic conditions in a nationwide, population-based cohort. Subjects were identified from Scottish hospital in-patient records from 1981 to 1996 and followed up by computer linkage of the Scottish Cancer Registry and the national registry of deaths. Expected cancer incidence was calculated from national cancer rates and related to the observed incidence by the standardized incidence ratio (SIR). Among RA patients, there was an increased risk for hematopoietic [males SIR= 2.13, 95% confidence interval (CI) 1.7-2.7; females SIR = 1.76, 95% CI 1.5-2.1], lung (males SIR = 1.32, 95% CI 1.2-1.5; females SIR = 1.44, 95% CI 1.3-1.6) and prostate (SIR = 1.26, 95% CI 1.0-1.6) cancers. Reduced risk were seen for colorectal cancer (males SIR = 0.87, 95% CI 0.7-1.1; females SIR = 0.71, 95% CI 0.6-0.9) and, among females, stomach cancer (SIR = 0.70, 95% CI 0.5-1.0). The excess risk for hematopoietic cancer and the reduced risk for colorectal and stomach cancers were sustained over 10 years of follow-up. An overall decreased risk of cancer was observed for patients with OA; the greatest reductions were observed for colorectal (males SIR = 0.88, 95% CI 0.8-1.0; females SIR = 0.84, 95% CI 0.8-0.9), stomach (males SIR = 0.79, 95% CI 0.7-0.9; females SIR = 0.66, 95% CI 0.6-0.8) and lung (males SIR = 0.72, 95% CI 0.7-0.8; females SIR = 0.84, 95% CI 0.8-0.9) malignancies, with decreased risks generally still evident at 10 years of follow-up. Our results support several previous findings regarding the incidence of hematopoietic and colorectal malignancies in RA patients. In addition, we have shown a large decrease in stomach cancer among patients with OA and females with RA that warrants further investigation since it may provide clues to possible prevention strategies. To further our knowledge about the underlying mechanisms of altered risk in cancer patients with rheumatic conditions, population studies requiring primary data collection are required. 相似文献

The Swedish Family-Cancer Database was used to analyse site-specific risk of second primary malignancies following 53 159 haematolymphoproliferative disorders (HLPD) diagnosed between 1958 and 1996. Standardized incidence ratio (SIR) of a second malignancy was calculated as the ratio of observed to expected numbers of second malignancies by applying site-, sex-, age-, period-, residence- and occupation-specific rates in the corresponding population in the Database to the appropriate person-years at risk. Among 18 960 patients with non-Hodgkin's lymphoma (NHL), there was over a 3-fold significant increase in cancer of the tongue, small intestine, nose, kidney and nervous system, squamous cell carcinoma (SCC) of the skin, NHL, Hodgkin's disease (HD) and lymphoid and myeloid leukaemia. Among 5353 patients with HD, there was over a 4-fold significant increase in cancer of the salivary glands, nasopharynx and thyroid, NHL and myeloid leukaemia, and over a 1.6-fold increase in cancer of the stomach, colon, lung, breast, skin (melanoma and SCC), nervous system and soft tissues and lymphoid leukaemia. Among 28 846 patients with myeloma and leukaemia, there was a significant increase in cancer of the skin, nervous system and non-thyroid endocrine glands and all HLPD except for myeloma. Our findings showed some clustering between first and second primaries among Epstein-Barr virus-, ultraviolet radiation- and immunosuppression-related cancers. 相似文献

Individuals with Down syndrome (DS) have a predisposition to leukaemia and testicular cancer, but data on the incidence of cancers are yet sparse. A cohort of 3,581 persons with DS was identified from a National Registry of Finnish persons with intellectual disability collected between 1978 and 1986 and followed-up for cancer incidence until 2002. Standardised incidence ratios (SIRs) were defined as ratios of observed number of cancer cases to those expected from the national cancer incidence rates, by age and sex. The overall cancer risk was equal to that of the general population, but a significantly high risk of leukaemia (SIR 10.5, CI 95% 6.6-15.8) and testicular cancer (SIR4.8, CI 95% 1.8-10.4) was found. 相似文献

The records of the Finnish Cancer Registry from 1953 to 1994 were used to assess the risk of subsequent primary cancer among 14,493 brain tumour patients. They had been treated with surgery only (n = 9804), radiotherapy (n = 4099), chemotherapy and radiotherapy (n = 493) or chemotherapy alone (n = 97). By the end of 1994, 403 subsequent primary cancers were registered in these patients, whilst the expected number based on national incidence was 332. The standardised incidence ratio (SIR) was 1.2 (95% confidence interval (CI) 1.1-1.3). A significant excess risk of tumours in the central nervous system (CNS) including meningeomas (SIR 2.6, 95% CI 1.7-3.8), non-Hodgkin's lymphoma (SIR 2.6, 95% CI 1.6-4.1) and skin melanoma (SIR 1.9, 95% CI 1.0-3.1) was observed. CNS tumours were observed in excess among patients treated with surgery alone (SIR 2.0, 95% CI 1.2-3.2) and with radiotherapy (SIR 5.1, 95% CI 2.5-9.4). In conclusion, brain tumours are associated with an increased risk of both CNS second tumours and non-CNS second cancers, especially non-Hodgkin's lymphoma and melanoma. A moderately increased risk of second tumours in the CNS was observed among brain tumour patients treated with surgery only and a larger excess among those treated with radiotherapy. 相似文献

Twenty-four Finnish families with 2 or more glioma patients were identified through questionnaires sent to 369 consecutive glioma patients receiving surgery at Tampere University Hospital during 1983-94. To explore whether unusual cancer susceptibility is involved, the cancer risk of 2,664 family members was estimated using population-based data from the Finnish Cancer Registry. Among the total cohort of relatives, 88 cancers were observed during 1953-97. The overall cancer risk among 12 families with juvenile onset gliomas was significantly decreased (standardized incidence ratio [SIR] 0.6, 95% confidence interval [CI]: 0.4-0.9). Among 12 families with adult onset gliomas, the overall cancer risk was equal to that of the reference population (SIR 1.1, 95% CI: 0.8-1.4) whereas the risk of skin melanoma (SIR 4.0, 95% CI: 1.5-8.8) and meningioma (SIR 5.5, 95% CI: 1.1-16) were significantly increased. Several other tumors, including those associated with neurofibromatosis 1 and 2, tuberous sclerosis and Li-Fraumeni and Turcot syndromes were surveyed, but no elevated risks were observed. In conclusion, the presence of meningiomas and skin melanomas in glioma families may indicate a novel association as a cancer susceptibility trait. 相似文献

Background
The epidemiology of secondary cancers in childhood cancer survivors has been unknown in Asian countries. Our aim is to assess the incidence and risk factors for secondary cancers through a nationwide survey in Japan.Methods
A retrospective cohort study comprising 10,069 children who were diagnosed with cancer between 1980 and 2009 was conducted in 15 Japanese hospitals. The cumulative incidence rate was calculated using death as the competing risk and compared by the Gray method. The standardized incidence ratio (SIR) was defined as the ratio of the number of observed cancers divided by the number of expected cancers. The risk factors were analyzed using Cox regression analysis.Results
One hundred and twenty-eight patients (1.3 %) developed secondary cancers within a median follow-up of 8.4 years. The cumulative incidence rate was 1.1 % (95 % confidence interval [CI] 0.9–1.4) at 10 years and 2.6 % (95 % CI 2.1–3.3) at 20 years after primary cancer diagnosis. Sensitivity analysis, limited to 5-year survivors (n = 5,387), confirmed these low incidence rates. The SIR of secondary cancers was 12.1 (95 % CI 10.1–14.4). In the Cox analysis, the hazard ratios for secondary cancers were 3.81 (95 % CI 1.53–9.47) for retinoblastoma, 2.78 (95 % CI 1.44–5.38) for bone/soft tissue sarcomas, and 1.81 (95 % CI 1.16–2.83) for allogeneic stem cell transplantation.Conclusions
The cumulative incidence of secondary cancers in children in Japan was not high; however, the SIR was relatively high. Retinoblastoma or sarcoma in addition to allogeneic stem cell transplantation were significant risk factors for secondary cancers.18.

The risk of a new primary cancer (NPC) among 77548 Finnish lung cancer patients from 1953 to 1995 was analysed by the histological type of the lung cancer. The relative risks were expressed as standardised incidence ratios (SIR, ratio of the observed and expected numbers of cases). During the follow-up, 1148 NPCs were observed among men and 152 among women. After exclusion of lung cancers, the risk of NPC was elevated in both males (SIR 1.07; 95% confidence interval (CI) 1.00-1.14) and females (SIR 1.21; 95% CI 1.02-1.42). The excess was larger among lung cancer patients with small-cell carcinoma and adenocarcinoma than those with squamous-cell carcinoma. In all major histological groups of lung cancer, significant excess risks were found for cancers of the larynx (SIRs 2.94-4.25), and bladder (SIRs 2.16-2.86). Significantly elevated SIRs were also found for cancers of the stomach (SIR 1.42; 95% CI 1.12-1.76) and kidney (SIR 2.18; 95% CI 1.56-2.97) in squamous-cell carcinoma; for brain tumours (SIR 3.26; 95% CI 1.20-7.09) in small-cell carcinoma; and for cancers of the prostate (SIR 1.68; 95% CI 1.21-2.27) and thyroid (SIR 3.79; 95% CI 1.23-8.85), and brain tumours (SIR 2.34; 95% CI 1.07-4.43) in adenocarcinoma. The risk of contracting NPC at sites where the majority of tumours are adenocarcinomas was elevated among patients with adenocarcinoma of the lung, but not among squamous-cell or small-cell carcinoma patients. In adenocarcinoma, the excess risks of several smoking-related cancers tended to be somewhat lower than those in the other two histological categories. The relative risk of a NPC among patients diagnosed with lung cancer in 1985-1995 was higher than that of patients from earlier periods in all comparable follow-up categories (up to 10 years), possibly suggesting that the increased use of cytostatic drugs had increased the risk of NPC. 相似文献

Ocular melanoma is a rare neoplasm with a poorly understood etiology, especially concerning its link with ultraviolet-light exposure. Studying the risk of second primary cancers may help to formulate causal hypotheses. We used data from 13 cancer registries, including 10,396 first occurring ocular melanoma cases, and 404 second occurring cases. To compare the second cancer incidence in ocular melanoma patients to that in noncancer population, we calculated standardized incidence ratios (SIRs) of 32 types of cancer. We also calculated SIRs of second ocular melanoma after other primaries. Ocular melanoma patients had significantly increased risk of cutaneous melanoma (SIR = 2.38, 95% CI 1.77-3.14), multiple myeloma (SIR = 2.00, 1.29-2.95), and of liver (SIR = 3.89, 2.66-5.49), kidney (SIR = 1.70, 1.22-2.31), pancreas (SIR = 1.58, 1.16-2.11), prostate (SIR = 1.31, 1.11-1.54), and stomach (SIR = 1.33, 1.03-1.68) cancers. Risks of cutaneous melanoma were highly variable between registries and were mainly increased in females, in younger patients, in first years following diagnosis, and for patients diagnosed after 1980. The risk of ocular melanoma was significantly increased only after prostate cancer (SIR = 1.41, 1.08-1.82). Risk of cutaneous melanoma after ocular melanoma had epidemiological patterns, similar to cutaneous melanoma screening in the general population. The increased risk of cutaneous melanoma would be largely due to greater skin cancer surveillance in ocular melanoma patients, and not to common etiological factors. The high SIR found for liver cancer may be explained by misclassification bias. Common etiological factors may be involved in ocular and prostate cancers. 相似文献
