A family diagnosed as cancer family syndrome because endometrial cancer was found in a member of this colorectal cancer-prone family was reported. The fact that uterine (endometrial) cancer was found in a family member during the serial follow-up of this family shows that there is no more than a difference of time between familial colorectal cancer and cancer family syndrome. The clinical significance of the familial cancer aggregation would be an important clue in the early detection of another new cancer in the family.

The importance of heredity in the etiology of endometrial cancer (EC) was examined in a series of 326 patients with EC diagnosed at age 60 years or less. If one or both of the proband's parents had died of cancer, a thorough family history of malignancies was studied. Altogether 291 cases with complete parental data were found. Nine kindred (3.1%) showed features compatible with the dominantly inherited cancer trait known as hereditary non-polyposis colorectal cancer (HNPCC). In another 9 cases, clustering of malignancies in 2 or more successive generations was indicative of familial cancer. Aspecific cancer aggregates were found in 112 probands' families, and family history was negative in 161 cases. No families had gynecological cancer as the only malignancy. HNPCC, the genetic etiology of which was recently revealed, seems to be an important risk factor for EC, indicating the significance of family-history investigations of all patients with EC. Colorectal carcinoma (CRC) was here associated with EC also in families with clusterings of malignancies, but in these families no typical features of any known hereditary cancer syndrome could be found. On the basis of the results of the present study, proper surveillance for colorectal cancer should be recommended for patients with endometrial carcinoma if they belong to a family with features indicative of HNPCC. Furthermore, healthy gene carriers in an HNPCC family also need careful surveillance for CRC, EC and perhaps for other extra-colonic malignancies typical for HNPCC. Prophylactic surgery should even be considered in these cases.

The isolation of genes that predispose to familial disease is an important goal in cancer research. The identification of such genes "opens up" the possibility of genetic diagnosis in families so that individuals who are at risk of cancer through inheriting a predisposing mutation can be identified. Genes that are involved in familial cancer syndromes may also be important in the pathogenesis of sporadic forms of the disease, which are often more common. In the search for genes that predispose to familial breast and ovarian cancer much recent progress has been made. A locus on the long arm of chromosome 17, in the interval 17q12-21, has been identified by genetic linkage, and appears to be responsible for disease in approximately 40% of breast cancer families and most families that contain breast and ovarian cancer. The region containing this locus, which has been called BRCA1, has been narrowed to a 3-4 cM interval defined by THRA1, the thyroid hormone receptor locus alpha, and D17S183, an anonymous microsatellite polymorphism. Loci other than BRCA1 that have been identified appear not only to predispose to breast and/or ovarian tumors, but to tumors at other sites too. A new locus has been identified on chromosome 2 which is linked to hereditary non-polyposis colorectal cancer (HNPCC). Families with HNPCC are also at risk of endometrial cancer and tumors of the ovary, amongst other cancer sites. Finally, mutations in the p53 gene are inherited in families with Li-Fraumeni syndrome, a rare cancer syndrome predisposing to breast tumors, sarcomas, leukemia and other cancers. Li-Fraumeni syndrome is also the only inherited cancer syndrome that predisposes at least in part to breast cancer where the actual predisposing gene is known. For the other cancer syndromes, the cloning of the predisposing genes is eagerly awaited.

Greggi and Kerlikowske have worked out that a woman has a 1.4% chance of developing ovarian cancer during her life. When cancer of the ovary is found, 5 to 10% of these cases have a familial form of this pathology. Thus there are some hereditary forms of cancer of the ovary and Lynch has demonstrated that there are three types of hereditary associations with ovarian neoplastic pathology: specific familial cancer of the ovary, cancer of the ovary associated with endometrial cancer and with non-polypoidal cancer of the caecum and rectum, cancer of the ovary associated with cancer of the breast. The clinical material we are presenting here is of the first type of association and we are reporting the study of a family in which 6 members in two generations had cancer of the ovary and of whom one had cancer of the breast as well. Familial cancer of the ovary shows different characteristics coming on as it does earlier (ten years earlier) and with a shorter length of survival (1.8 as against 5 years). The risk of the next generation having ovarian neoplastic pathology is clear because there is a 50% chance in a patient who has a history of cancer of the ovary in at least two first degree relatives. For most daughters when this type of familial cancer is found it is justifiable to carry out prophylactic oophorectomy from the age of 35 year onwards. Particular supervision should be carried out for patients who are members of a family where 2 index cases have been found within 20-35 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Familial ovarian cancer is described as a familial aggregation of ovarian cancer. The disease is heterogeneous, with at least three genotypes prodisposing to distinctive hereditary syndrome, site-specific ovarian cancer, wherein familial cancer risk is restricted to ovarian carcinoma; breast/ovary carcinoma syndrome, that is ovarian carcinoma in association with carcinoma of the breast; and Lynch syndrome II, characterized by hereditary nonpolyposis colorectal cancer with proximal colonic cancer predominance, endometrial carcinoma, and ovarian carcinoma. When a familial aggregation of ovarian cancer is observed, unaffected women in the family should have periodic gynecologic examinations, including cytologic and ultrasonographic, radiologic studies and magnetic resonance imaging, in an effort to detect preinvasive ovarian cancer. Until more reliable diagnostic methods are developed, however, the physician should consider the advisability of prophylactic oophorectomy and oral contraceptives when counseling women who have several close relatives with ovarian cancer.

We evaluated the incidence of synchronous or metachronous multiple primary cancer, hereditary or familial cancer, and the familial aggregation of cancer in 142 patients who were treated for endometrial cancer at Tsukuba University Hospital in the period 1977 to 1995. Synchronous multiple primary cancers were identified in 6 of the 142 patients (4.2%). Eleven patients (7.7%) had a history of extraendometrial cancer. Patients with endometrial cancer had a significantly high incidence of a history of breast cancer. Endometrial cancer was diagnosed in two patients who were screened before menopause. Four patients with endometrial cancer (2.8%) subsequently developed extraendometrial forms of cancer. One patient (0.7%) was considered to have a hereditary form of cancer, and 5 patients (3.5%) had familial forms of cancer. A total of 86 cases of cancer were found among 53 kindred (37.3%). More detailed studies are needed to elucidate the aggregation of cancers in the families of patients with endometrial cancer in Japan. Patients with a history of breast cancer should be screened for the presence of endometrial cancer.

The aim of this study was to perform a clinical and immunohistochemical comparison between simultaneous independent tumors involving endometrium and ovary and metastatic endometrial tumors, and to try to find clinical and /or immunohistochemical parameters differentiating between these two entities. Sixteen cases of simultaneous independent primaries of endometrium and ovary, presenting the same histologic type, were compared with 12 cases of primary endometrial cancer, demonstrating ovarian metastases. The comparison related to patients' characteristics and immunohistochemical expression of estrogen and progesterone receptors (ER,PR), bcl-2, HER-2 /neu, p53, and cell proliferation marker Ki-67 in endometrial and ovarian tumors. The only clinical parameter differentiating significantly between the groups was the prevalence of familial cancer, being more frequent in the group of metastatic tumors (P = 0.03). Immunohistochemical analysis demonstrated the same immunostaining in endometrium and ovary for all immunohistochemical parameters in cases of metastatic endometrial cancer. Conversely, 62.5% of cases with simultaneous tumors of endometrium and ovary could be differentiated from metastatic tumors by distinct immunohistochemical expression of ER and PR in endometrial and ovarian tumors (P = 0.0006), and 31.3% of cases could be differentiated by distinct immunostaining for bcl-2 (P = 0.03). Immunohistochemical parameters HER-2 /neu, p53 and Ki-67 were not appropriate for the distinction between the two study groups. We conclude that the application of immunohistochemical analysis may play an important role in the differentiation between cases of simultaneous independent carcinomas of endometrium and ovary vs. cases of endometrial carcinoma with ovarian metastases.

Lee S-C, Guo J-Y, Lim R, Soo R, Koay E, Salto-Tellez M, Leong A, Goh B-C. Clinical and molecular characteristics of hereditary non-polyposis colorectal cancer families in Southeast Asia. Hereditary non-polyposis colorectal cancer (HNPCC), predominantly due to germline MLH1/MSH2 mutations, is the commonest form of hereditary colorectal cancer (CRC), but data in Asians are sparse. We sequenced the MLH1/MSH2 coding and promoter core regions in CRC patients diagnosed below age 40, and/or with multiple primary cancers or familial cancer clustering suggestive of HNPCC, and correlated deleterious mutations with clinical and tumour features. Forty-six Chinese, Malay and Indian kindreds participated. Of the 153 cancers reported in the 46 kindreds, stomach (14%) and urogenital cancers (13%) were the most common extracolonic cancers, whereas endometrial cancer comprised only 7%. Eleven different MLH1 and 12 MSH2 mutations were identified, including nine novel and four recurring mutations in the Chinese. One Indian was a compound heterozygote for an MLH1 and MSH2 mutation. The MLH1/MSH2 mutation data in the Malays and the Indians represents the first in these ethnic groups. Factors strongly associated with deleterious mutations were the Amsterdam criteria, family history of stomach or multiple primary cancers, and MSI-high tumours, whereas family history of endometrial cancer and young cancer age alone correlated poorly. Distinct clinical and molecular characteristics were identified among Asian HNPCC kindreds and may have important clinical implications.

A literature search was carried out for clinical observations that could explain the possible aetiology of primary peritoneal clear cell carcinoma (CCC) including diagnostic dilemmas, various theories of origin, oestrogen dependence and genetic association. It was found to be an extremely rare tumour (CCC) arising in the peritoneum and is often misdiagnosed as mesothelioma or serous carcinoma or metastatic adenocarcinoma due to overlapping morphological features. The awareness of such dilemmas is important even before making a diagnosis. Clinicopathological features and immunohistochemical studies like WT1, CK20 and calretinin are usually helpful in differentiating CCC from serous carcinoma, metastatic carcinoma from bowel and mesothelioma. (CK7 is common to all epithelial tumours, CEA can be expressed in clear cell carcinoma, WT1 is normally expressed in serous carcinoma, calretinin is expressed in mesothelioma and CK20 in colon carcinoma). The distinction between the above tumours is important as correct diagnosis is required in initiating appropriate treatment. Less than ten cases have been reported in the English language medical literature. Mullerian metaplasia and malignant transformation in endometriosis are two theories proposed for its existence. Peritoneal CCC can be oestrogen dependent in view of association with oestrogen dependent conditions which include endometriosis, adenomyosis and endometrial carcinoma. A genetic ascertain is difficult to be associated and needs further evaluation in a research setting in the familial cancer genetic clinics.

Lynch syndrome (LS) is an autosomal dominant familial cancer risk syndrome that occurs due to a germline mutation in one of several mismatch repair genes and is associated with an increased risk of colorectal, endometrial, and ovarian cancer. The risk of endometrial cancer equals or exceeds that of colorectal cancer in women with LS. The diagnosis of gynecologic cancer precedes that of colorectal cancer in over half of women with metachronous gynecologic and colon cancers, making gynecologic cancer a "sentinel cancer" for LS. There are no studies addressing the effectiveness or safety of chemoprevention for women with LS. Surveillance with gynecologic examination including assessment of symptoms, transvaginal pelvic ultrasonography, endometrial biopsy, and CA125 tumor marker assessment can be offered, but has not been shown to improve outcomes for these patients. Prophylactic hysterectomy with bilateral salpingo-oophorectomy performed after the completion of childbearing may be offered for gynecologic cancer prevention.
