    • Background: Although advances in the treatment of myeloid neoplasms have led to improved patient survival, this improvement has been accompanied by an increased risk of second primary cancer (ie, the risk of another cancer after myeloid neoplasia). We aimed to assess bi-directional associations between myeloid cancers and other cancers—ie, development of second primary cancer in patients who have previously had myeloid cancer, and risks of myeloid neoplasia in patients who have previously had another cancer—to provide insight into possible mechanisms beyond side-effects of treatment and shared risk factors. Methods: Using the Swedish Family-Cancer Database, we identified 35 928 individuals with primary myeloid cancer, including myeloproliferative neoplasms, acute myeloid leukaemia, chronic myeloid leukaemia, and myelodysplastic syndrome diagnosed between 1958 and 2015. The Swedish Family-Cancer Database includes every individual registered as a resident in Sweden starting in 1932, with full parental history. The primary endpoint was the assessment of relative risks (RRs) for second primary cancer, which we performed using means of incidence rate ratios, regressed over a generalised Poisson model. Findings: Between 1958 and 2015, overall relative risk of second primary cancers was significantly increased after acute myeloid leukaemia (RR 1·29, 95% CI 1·17–1·41), chronic myeloid leukaemia (1·52, 1·35–1·69), myelodysplastic syndrome (1·42, 1·26–1·59), and all myeloproliferative neoplasms (1·37, 1·30–1·43) relative to the incidence of these cancers as first primary cancer. With myeloid neoplasia as a second primary cancer, risks were significantly increased for acute myeloid leukaemia (1·57, 1·48–1·65), chronic myeloid leukaemia (1·26, 1·13–1·40), and myelodysplastic syndrome (1·54, 1·42–1·67) relative to the incidence of these myeloid neoplasms as first primary cancers. Relative risk of upper aerodigestive tract cancer, squamous cell skin cancer, and non-Hodgkin lymphoma as second primary cancers were increased after all four types of myeloid neoplasia relative to their incidence as first primary cancers. High risks of myelodysplastic syndrome and acute myeloid leukaemia as second primary cancers were found after haematological cancers (RRs between 5·08 and 10·04). Interpretation: The relative risks of second primary cancer are important for the long-term management of patients with myeloid cancers. The bi-directional associations of myeloid cancers with many other cancers suggest a number of candidate mechanisms that might contribute to the development and aetiology of a second primary cancer. These mechanisms might include immune dysfunction or the effects of treatment, and these should be assessed in future investigations.

  • Second primary cancers in non-Hodgkin lymphoma : Bidirectional analyses suggesting role for immune dysfunction
  • 2018
  • Ingår i: International Journal of Cancer. - John Wiley and Sons Inc.. - 0020-7136. ; 143:10, s. 2449-2457

    • Second primary cancers (SPCs) account for an increasing proportion of all cancer diagnoses. It is unlikely that prior therapy is solely responsible for SPC risk. To investigate risk of SPC after diagnosis of non-Hodgkin lymphoma (NHL) and 10 of its subtypes we conducted a novel bidirectional analysis, SPCs after NHL and NHL as SPC. Using the Swedish Family-Cancer Database, we identified 19,833 individuals with primary NHL diagnosed between 1993 and 2015. We calculated relative risks (RRs) of SPCs in NHL survivors and, for bi-directional analysis, risk of NHL as SPC. The overall RRs were significantly bidirectionally increased for NHL and 7 cancers. After diagnosis of NHL risks were increased for upper aerodigestive tract (RR = 1.96), colorectal (1.35), kidney (3.10), bladder (1.54) and squamous cell skin cancer (SCC) (4.12), melanoma (1.98) and Hodgkin lymphoma (9.38). The concordance between RRs for each bidirectional association between NHL and 31 different cancers was highly significant (r = 0.86, p < 0.0001). Melanoma was bidirectionally associated with all 10 subtypes of NHL. The observed bidirectional associations between NHL and cancer suggest that therapy-related carcinogenic mechanisms cannot solely explain the findings. Considering that skin SCC and melanoma are usually treated by surgery and that these cancers and NHL are most responsive of any cancer to immune suppression, the consistent bidirectional results provide population-level evidence that immune suppressed state is a key underlying mechanism in the context of SPCs. Furthermore, the quantified risks for NHL subtypes have direct clinical application in the management of NHL patients.

  • Concordant and discordant familial cancer : Familial risks, proportions and population impact
  • 2017
  • Ingår i: International Journal of Cancer. - John Wiley and Sons Inc.. - 0020-7136. ; 140:7, s. 1510-1516

    • Relatives of cancer patients are at an increased risk of the same (concordant) cancer but whether they are at a risk for different (discordant) cancers is largely unknown - beyond well characterized hereditary cancer syndromes - but would be of major scientific and clinical interest. We therefore decided to resolve the issue by analyzing familial risks when family members were diagnosed with any discordant cancers. We compared the population impact of concordant to discordant familial cancer. The Swedish Family-Cancer Database (FCD) was used to calculate familial relative risks (RRs) for family members of cancer patients, for the 27 most common cancers. Population attributable fractions (PAFs) were estimated for concordant and discordant family histories. Discordant cancers in the family were detected as significant risk factors for the majority of cancers, although the corresponding RRs were modest compared to RRs for concordant cancers. Risks increased with the number of affected family members with the highest RRs for pancreatic (2.31), lung (1.69), kidney (1.98), nervous system (1.79) and thyroid cancers (3.28), when 5 or more family members were diagnosed with discordant cancers. For most cancers, the PAF for discordant family history exceeded that for concordant family history. Our findings suggest that there is an unspecific genetic predisposition to cancer with clinical consequences. We consider it unlikely that shared environmental risk factors could essentially contribute to the risks for diverse discordant cancers, which are likely driven by genetic predisposition. The identification of genes that moderately increase the risk for many cancers will be a challenge.

  • Common cancers share familial susceptibility : Implications for cancer genetics and counselling

  • Tidskriftsartikel (refereegranskat)abstract
    • Background It has been proposed that cancer is more common in some families than in others, but the hypothesis lacks population level support. We use a novel approach by studying any cancers in large threegeneration families and thus are able to find risks even though penetrance is low. Methods Individuals in the nation-wide Swedish Family- Cancer Database were organised in three generations and the relative risk (RR) of cancer was calculated to the persons in the third generation by the numbers of patients with cancer in generations 1, 2 and 3. Results The RRs for any cancer in generation 3 increased by the numbers of affected relatives, reaching 1.61 when at least seven relatives were diagnosed. The median patient had two affected relatives, and 7.0% had five or more affected relatives with an RR of 1.46, which translated to an absolute risk of 21.5% compared with 14.7% in population by age 65 years. For prostate cancer, the RR was 2.85 with four or more affected family members with any cancer, and it increased to 14.42 with four or more concordant cancers in family members. RRs for prostate cancer were approximately equal (2.70 vs 2.85) if a man had one relative with prostate cancer or four or more relatives diagnosed with any cancer. Conclusions A strong family history of cancer, regardless of tumour type, increases cancer risk of family members and calls for mechanistic explanations. Our data provide tools for counselling of patients with cancer with both low and high familiar risks.

  • Familial Associations of Colon and Rectal Cancers With Other Cancers
  • 2019
  • Ingår i: Diseases of the Colon and Rectum. - Springer. - 0012-3706. ; 62:2, s. 189-195
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Many studies have indicated that colon and rectal cancers differ in etiology and histology. OBJECTIVE: The aim of this study was to investigate whether the associations of colon and rectal cancers with any other (discordant) cancer were site specific. DESIGN: A novel approach was implemented in which cancer risks were analyzed in families with increasing numbers of family members diagnosed with defined cancers. The novel assumption was that, for a true familial association, the risk should increase by the number of affected family members. In separate analyses, familial risks were calculated after the exclusion of putative families with hereditary nonpolyposis colorectal cancer. SETTINGS: The study was conducted using the Swedish Family-Cancer Database. MAIN OUTCOME MEASURES: The outcome measure was relative risk. RESULTS: Relative risks of colorectal cancer and colon cancer were higher when family members were diagnosed with colon cancer than when family members were diagnosed with rectal cancer (incidence rate ratio for colorectal: 1.82 (95% CI, 1.74-1.90) vs 1.61 (95% CI, 1.51-1.71); incidence rate ratio for colon: 1.92 (95% CI, 1.83-2.02) vs 1.56 (95% CI, 1.45-1.69)). Relative risks for 10 discordant cancers were increased in colon or rectal cancer families, whereas none of the relative risks differed significantly between colon and rectal cancers. After deleting hereditary nonpolyposis colorectal cancer families, the relative risks of endometrial and ovarian cancers were no longer significant. LIMITATIONS: Genetic data are unavailable in the database. CONCLUSIONS: Our results suggested that familial risks for colon cancer were higher than risks for rectal cancer in families of patients with colorectal cancer and colon cancer. The relationships of lung cancer and nervous system cancer with colorectal cancer were site specific. The associations of colon and rectal cancers with lung cancer, myeloma, and cancer of unknown primary appeared not to point out known syndromes and may suggest involvement of a novel predisposition.

  • Familial associations of colorectal cancer with other cancers

    • Colorectal cancer (CRC) has a strong familial component which extends to discordant cancers (ie non-CRC tumors). This is best seen in cancer syndromes such as hereditary non-polyposis colorectal cancer (HNPCC) which predisposes to several tumor types. Population-based family studies have also found discordant associations for CRC but they have included cancers which manifest in HNPCC, and there is no convincing evidence of discordant associations beyond the known syndromes. We address familial associations of non-CRC tumors with CRC using the resources of the Swedish Family-Cancer Database and applying a powerful approach of assessing familial relative risks in families of increasing numbers of patients with discordant cancers. Among 1.8 million cancer patients and over 200,000 CRC cases consistent familial associations of CRC was observed for several HNPCC related cancers. However, for small intestinal, pancreatic and nervous system cancers RRs remained essentially unchanged when potential HNPCC families were excluded, suggesting involvement of genes not related to HNPCC. Two independent associations of CRC were found for melanoma, thyroid and eye cancers and these appeared not to be related to known syndromes. A number of other cancers associated with CRC in single analyses and independent studies are required to assess the relevance of such findings.

  • Familial Urinary Bladder Cancer with Other Cancers
  • 2018

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Family risks for urinary tract cancers (excluding kidney cancers) are known, but less is known about whether rare urinary tract cancer subtypes are also familial and if urinary tract cancers share familial risk for other (discordant) cancers. Objective: To investigate the impact of family history on urinary tract cancers (International Classification of Diseases version 7 code 181) and discordant cancers. Design, setting, and participants: The Swedish Family-Cancer Database, the largest family data set in the world, was used to assess familial risks between 86 058 patients with urinary tract cancers and patients with other cancers between 1958 and 2015. Outcome measurements and statistical analysis: A Poisson regression model was used to generate relative risks (RRs). Results and limitations: Some 7.0% of patients with urinary tract cancers had a parent or sibling diagnosed with the same cancer, yielding an RR of 1.81 (95% confidence interval [CI] 1.68–1.94). As novel familial findings, we also found that ureter (RR 1.62, 95% CI 1.04–2.53) and transitional cell in situ tumors (RR 2.04, 95% CI 1.49–2.80) were associated with urinary tract cancers. The most consistent discordant familial associations of urinary tract cancers were with smoking-related sites of cancer: lung, stomach, and kidney. Internally consistent familial associations not related to smoking were found for endometrial and thyroid cancers. Familial associations with urinary tract cancers were also found for rare anal, female genital, and cervical cancers. The main limitation was a lack of data on smoking. Conclusions: Smoking-related cancers were associated with urinary tract cancer. We speculate that familial clustering of endometrial and thyroid cancers with urinary tract cancers may be ascribed to obesity. Patient summary: Diagnosis of bladder cancer in a close family member may be a sign of higher risk among other family members. Patients and family members should be told that bladder cancer is smoking-related and they should be counseled to recognize blood in urine as a possible early sign. The relative risk of familial urinary tract cancer was 1.81 for individuals with a parent or sibling diagnosed with the same cancer. Such familial cases accounted for 7.0% of patients with urinary tract cancers. Familial risk was equally high for ureter and transitional cell in situ tumors. The incidence of some other cancers, particularly smoking-related cancers, was higher among families of patients with urinary tract cancer.

    • Familial risks of lung cancer are well-established, but whether lung cancer clusters with other discordant cancers is less certain, particularly beyond smoking-related sites, which may provide evidence on genetic contributions to lung cancer aetiology. We used a novel approach to search for familial associations in the Swedish Family-Cancer Database. This involved assessment of familial relative risk for cancer X in families with increasing numbers of lung cancer patients and, conversely, relative risks for lung cancer in families with increasing numbers of patients with cancers X. However, we lacked information on smoking. The total number of lung cancers in the database was 125 563. We applied stringent statistical criteria and found that seven discordant cancers were associated with lung cancer among family members, and six of these were known to be connected with smoking: oesophageal, upper aerodigestive tract, liver, cervical, kidney and urinary bladder cancers. A further novel finding was that cancer of unknown primary also associated with lung cancer. We also factored in histological evidence and found that anal and connective tissue cancers could be associated with lung cancer for reasons other than smoking. For endometrial and prostate cancers, suggestive negative associations with lung cancer were found. Although we lacked information on smoking it is prudent to conclude that practically all observed discordant associations of lung cancer were with cancers for which smoking is a risk factor.
