Abstract
Familial risk of ovarian cancer is well-established but whether ovarian cancer clusters with other cancers and the clusters differ by histology remains uncertain. Using data from the Swedish Family-Cancer Database, we explored familial associations of ovarian cancer with other cancers with a novel approach; relative risk for (histology-specific) ovarian cancer was estimated in families with patients affected by other cancers, and conversely, risks for other cancers in families with (histology-specific) ovarian cancer patients. Eight discordant cancers were associated with ovarian cancer risk, of which family history of breast cancer showed a dose-response (P-trend <0.0001). Conversely, risks of eight types of cancer increased in families with ovarian cancer patients, and dose-responses were shown for risks of liver (P-trend = 0.0083) and breast cancers (P-trend <0.0001) and cancer of unknown primary (P-trend = 0.0157). Some cancers were only associated with histology-specific ovarian cancers, e.g. endometrial cancer was only associated with endometrioid type but with highest significance. Novel associations with virus-linked cancers of the nose and male and female genitals were found. The results suggest that ovarian cancer shares susceptibility with a number of other cancers. This might alert genetic counselors and challenge approaches for gene and gene-environment identification.

Abstract
Successes in cancer therapy have led to increasing numbers of cancer survivors, who are at risk of developing second primary cancers. Therapy- or disease-induced suppression of the immune function may predispose cancer patients to a second malignancy. An excess of squamous cell skin cancers (SCC) and non-Hodgkin's lymphomas has been found in immunosuppressed patients. We used the nationwide Swedish Family-Cancer Database on 10.2 million individuals to calculate the risk of second primary skin cancers and non-Hodgkin's lymphomas following a previous malignancy. A total of 4301 second skin cancers and 1672 non-Hodgkin's lymphomas were identified. Standardised incidence ratios (SIR)s and 95% Confidence Intervals (CIs) were calculated and compared. Among 14 different sites for male or female first primary malignancies, 11 of these sites were followed by an increased risk of skin cancer (SIRs for males for risk of skin cancer as a second primary cancer: 14.1 for SCC; 9.7 for melanoma; 6.1 for leukaemia as the first site; SIRs for females for risk of skin cancer: 14.6 for SCC; 6.8 for larynx; 6.2 for upper aerodigestive tract (UADT) as the first site). The risk of non-Hodgkin's lymphoma was increased after 10 of 14 different male neoplasms and 12 of 17 different female neoplasms. (SIRs for males for risk of non-Hodgkin's lymphoma as a second primary cancer: 6.4 for non-Hodgkin's lymphoma; 3.2 for leukaemias; 3.1 for multiple myeloma as the first site; SIRs for females for risk of non-Hodgkin's lymphoma as a second primary cancer: 12.5 for leukaemias; 7.0 for Hodgkin's disease; 3.6 for UADT as the first site). The high, and after certain sites, very high risks of second skin cancer and non-Hodgkin's lymphoma suggest that immune suppression may be a contributory mechanism.

Abstract
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.
