The nationwide survey of institutions with MHTS and human dry dock capabilities was analyzed and the following results have been obtained. 1) The relative rates of cancer detection by sex and organ were the stomach > colon > rectum > lung > kidney > esophagus for men and the stomach > breast > uterus > colon > thyroid > lung for women. 2) Gastric cancer takes first place in the ranking of rates of cancer detection in the population of both sexes, followed by colon cancer. The difference in rate of detection between these cancers has been narrowed from year to year. In 1997, the ratio of gastric to colon cancers was 10:7. 3) Early cancers account for 74% of gastric cancer patients and 75% of colon cancer patients. 4) Since gastric and colon cancers are detected early, the proportions of persons with gastrointestinal symptoms are as low as 28% for gastric cancer patients and 26% for colon cancer patients. 5) The relative rates of cancer detection by the degree obesity are normal > obese > lean person. The rates of gastric and colon cancers are 2- and 3-fold higher for obese persons than for lean persons, respectively. Gastric and colon cancers are detected with higher frequency in well-nourished persons. The present review of the national MHTS and human dry dock statistics has confirmed the efficacy of MHTS and human dry dock, especially in the examination for gastrointestinal cancers.

WNT2 is one of proto-oncogenes with the potential to activate the WNT - beta-catenin - TCF signaling pathway, which is most homologous to WNT2B among members of the human WNT gene family. Here, expression of WNT2 mRNA was comprehensively investigated. WNT2 mRNAs were highly expressed in fetal lung, and weakly expressed in placenta. Among 2.0-, 2.9-, 4.1-, and 6.0-kb WNT2 mRNAs, the 2.0-kb WNT2 mRNA was the major transcript in fetal lung. In 3 cases of prostate cancer and 1 case each of lung cancer and cervical cancer, WNT2 was over-expressed in non-cancerous portion as well as in primary tumor. WNT2 was up-regulated in 14 out of 18 cases of primary colorectal cancer, 4 out of 7 cases of uterus tumor, 2 out of 9 cases of breast cancer, and in 2 out of 14 cases of kidney tumor. Up-regulation of WNT2 was also detected in 4 out of 8 cases of primary gastric cancer by using expression array filter hybridization, and in 10 out of another 10 cases of primary gastric cancer by using cDNA-PCR. Frequent up-regulation of WNT2 in primary gastric cancer and colorectal cancer might play a key role in carcinogenesis through activation of the WNT - beta-catenin - TCF signaling pathway.

WNT signal is transduced to the beta-catenin - TCF pathway, the JNK pathway, or the Ca2+-releasing pathway through seven-transmembrane-type WNT receptors encoded by Frizzled genes (FZD1-FZD10). We have previously cloned and characterized human WNT2B/WNT13, WNT3, WNT3A, WNT5B, WNT6, WNT7B, WNT8A, WNT8B, WNT10A, WNT10B, WNT11, WNT14, and WNT14B/WNT15 by using bioinformatics, cDNA-library screening, and cDNA-PCR. Here, we investigated expression of human WNT5A mRNA in various normal tissues, 66 primary tumors derived from various tissues, and 15 human cancer cell lines. WNT5A mRNA was relatively highly expressed in salivary gland, bladder, uterus, placenta, and fetal kidney. Up-regulation of WNT5A mRNA was detected in 5 out of 8 cases of primary gastric cancer, 5 out of 18 cases of primary colorectal tumors, and in 2 out of 7 cases of primary uterus tumors by using matched tumor/normal expression array analysis. Up-regulation of WNT5A mRNA was also detected in 7 out of 10 other cases of primary gastric cancer by using cDNA-PCR. Although low-level expression of WNT5A mRNA was detected in gastric cancer cell line MKN45, WNT5A mRNA was almost undetectable in gastric cancer cell lines OKAJIMA, TMK1, MKN7, MKN28, MKN74, and KATO-III. Compared with frequent up-regulation of WNT5A mRNA in primary gastric cancer, expression levels of WNT5A mRNA in 7 gastric cancer cell lines were significantly lower than that in normal stomach. Frequent up-regulation of WNT5A mRNA in human primary gastric cancer might be due to cancer-stromal interaction.

Trends in mortality rates are usually presented per tumour site or per country without an overall analysis of the complete data encompassing all three aspects (tumour sites, countries, trends). This paper presents a methodology for such an overall analysis using three-way methods applied to a data set on female mortality rates for 17 tumour sites of 43 countries for the years 1968-1985. Multivariate techniques like biplots and three-mode principal component analysis within an overall three-way analysis-of-variance framework were used. We confirmed the known patterns of comparatively high mortality for women due to cancer of the bladder, intestines, pancreas, rectum, breast, ovary, skin and leukaemia and the relatively low mortality rates for liver cancer in Western and Northern Europe, the USA, Australia and New Zealand. Also, the reverse pattern was observed for Middle and Southern Europe, Hong Kong, Singapore, and in Japan, and in some but not all Latin American countries. The relatively mortality due to cancer was high in the lungs, mouth, larynx and oesophagus in the British Isles, but was much less in other European countries. Mortality due to cancer of the thyroid, uterus, gall bladder and stomach was high in Middle European countries, as was the case in Japan, Chile and Costa Rica. Rates were low for Southern European countries, North America, Australia and New Zealand. Specific deviating patterns in the data were the more rapidly decreasing mortality rates for stomach cancer in Chile and Japan and the more rapidly increasing mortality rates for lung cancer in the USA, Scotland and Denmark. In conclusion, using three-way methods, it was feasible to analyse the cancer mortality data in their entirety. This enabled the simultaneous comparison of trends in relative mortality rates between all countries due to all tumour sites, as well as the identification of specific deviating trends for specific tumour sites in specific countries.

Presented is a rare case of bilateral neoplastic metastases to the ovaries (Krukenberg's tumors) and to the fundus of the uterus which occurred in the course of stomach cancer in a 46-year-old female who was treated surgically in the Department of Obstetrics and Gynecology of the Regional Hospital in Slupsk. The patient was admitted secondary to bilateral ovarian masses. Her past medical history included peptic ulcer disease for a few years, confirmed by gastroscopic biopsy in July of 2000. The surgery performed in our department revealed bilateral ovarian tumors, each measuring about 10 cm in diameter, which were completely removed along with the fundus of the uterus. The intraoperative histologic diagnosis was ovarian cancer. No other macroscopic neoplastic changes were found during the surgery. During surgical removal of the gastrocolic ligament a group of enlarged lymph nodes at the greater curvature of the stomach in the proximity of the spleen was incidentally noticed. The intraoperative histology of the lymph nodes described metastatic neoplasia. Another intraoperative biopsy was also performed of the stomach because of atypical clinical presentation of the ovarian cancer. The pathologic diagnosis was stomach cancer. Upon the consultation with pathologists it was concluded that the primary tumor came from the stomach while the changes in the ovaries and lymph nodes were metastatic. Thus, the surgery consisted of total hysterectomy as well as removal of the stomach along with the spleen, gastrocolic ligament and greater omentum. The distal esophagus was anastomosed with the loop of jejunum. The final result of histologic exam confirmed the location of the primary neoplastic tumor in the stomach with metastases to both ovaries, the body of uterus, and lymph nodes at the greater curvature of the stomach.

Drosophila prickle is implicated in tissue polarity or planar polarity. Here, human PRICKLE1 gene corresponding to FLJ31937 cDNA and human PRICKLE2 gene corresponding to DKFZp686D143 cDNA were identified to be homologous to Drosophila prickle gene by using bioinformatics. PRICKLE1 gene was mapped to human chromosome 12p11-q12, and PRICKLE2 gene was mapped to human chromosome 3p14. Mouse Prickle1 and Prickle2 genes were next identified in mouse genome draft sequences NW_000106.1 and NW_000262.1, respectively. Human PRICKLE1, PRICKLE2, Xenopus Prickle, and Drosophila prickle were homologous in the PET domain, three LIM domains, and the C-terminal Prickle homologous (PKH) domain. LMO6 and TESTIN, containing the PET domain and three LIM domains, were found to lack the PKH domain. Therefore, PRICKLE1 and PRICKLE2 rather than LMO6 and TESTIN were found to be human homologs of Drosophila prickle. PRICKLE1 and PRICKLE2 mRNAs were expressed together in brain, eye and testis. PRICKLE1 mRNA was expressed in fetal heart and hematological malignancies, while PRICKLE2 mRNA in fetal brain, adult cartilage, pancreatic islet, gastric cancer with signet-ring cell features, and uterus tumors. Because tissue polarity genes frizzled, dishevelled, flamingo, and Vang are evolutionary and functionary conserved from Drosophila to human, PRICKLE1 and PRICKLE2 might be implicated in the localization of Frizzled and Dishevelled proteins, just like Drosophila prickle. This is the first report on identification and characterization of human PRICKLE1, PRICKLE2, mouse Prickle1, and Prickle2 genes.

After long-term rises, over the last decade age-standardised mortality from most common cancer sites has fallen in the European Union (EU). For males, the fall was 11% for lung and intestines, 12% for bladder, 6% for oral cavity and pharynx, and 5% for oesophagus. For females, the fall was 7% for breast and 21% for intestines. There were also persisting declines in stomach cancer (30% in both sexes), uterus (mainly cervix, -26%) and leukaemias (-10%). Mortality rates for other common neoplasms, including pancreas for both sexes, prostate and ovary, tended to stabilise. The only unfavourable trends were observed for female lung cancer (+15%). Lung cancer rates in women from the EU are approximately one-third of those in the USA, and 50% lower than breast cancer rates in the EU. Lung cancer rates in European women have also tended to stabilise below the age of 75 years. Thus, effective interventions on tobacco control could, in principle, avoid a major lung cancer epidemic in European women.

This report brings the latest statistics available in the Cancer Register of Navarra on the incidence of cancer in this autonomous community in the year 1998. 3,018 incident cases of cancer were registered, 57.5% in men. Excluding nonmelanoma skin tumours, the crude incidence rate was 518 and 358 per 100,000 in men and women, and the rates adjusted to the world population were 296 and 199 per 100,000 respectively. 55.4% of all the cases of cancer diagnosed in men during 1998 occurred in the following sites: prostate, lung, colorectal, and bladder. In women breast, colorectal, body of uterus and stomach sites made up 53.6% of the cases. With respect to the five year period 1993-97, for the first time the adjusted incidence rate for all sites combined showed a decline of 1.1% amongst men, while amongst women the rising tendency was upheld. Notable were the decline of tumours related to smoking amongst men and of stomach cancer in both sexes. The data for women seem to indicate that some sites which traditionally showed extremely low rates in Navarra, tumours related to smoking and the cervix, have begun to increase in recent years, probably in relation to changes of life style. In both sexes there was an increase of non-Hodgkin's lymphomas and, continuing the tendency begun in previous years, the rate of incidence of breast cancer in women and prostate cancer in men continued to increase. The decline in the incidence of some cancers, particularly for the sites related to smoking observed amongst men in Navarra, is a hopeful fact, which will need confirmation in coming years.

Between 1993-1997, there were 14,023 new cases of cancer registered in Navarra. In men, the most frequently diagnosed cancers were in the following order: lung, prostate, colon and rectum, stomach and bladder, which accounted for 60% of all the cancer cases. In women the sites of breast, colon and rectum, body of uterus, stomach and ovary accounted for 57% of the total number of cases. In the same period, 1993-1997, 3,875 men and 2,332 women died of cancer. 60% of all the deaths caused by malignant tumours in men were due to the sites of lung, colon and rectum, prostate, stomach and bladder. In women the sites of breast, colon and rectum, stomach, pancreas and liver, accounted for 51% of deaths from cancer. Amongst men in Navarra there has been an important increase in the last two decades of the rates of incidence and mortality of cancers related to the habit of smoking (lung, oral cavity and pharynx or pancreas). The global risk of dying from cancer was higher in the late 90s than in the 70s and 80s. From 1995 onwards, cancer mortality advanced from second place to occupy the first place as the cause of death amongst men in Navarra. Amongst women, cardiovascular diseases continue to be the first cause of death. Amongst women the global risk of death from cancer fell by 20% between 1975 and 1997, due principally to a fall in cases of stomach cancer. Tumours related to the habit of smoking have not so far shown substantial increases amongst women in Navarra. Breast cancer has increased in recent years, although its incidence and mortality amongst women in Navarra continues to be somewhat lower than the average in the European Union and the United States. Invasive cervical cancer remains at very low rates with respect to many European countries, including Spain. In both sexes there has been an increase in colorectal cancer and melanoma, while the incidence and mortality of stomach cancer continues to fall.

A family history (FH) of breast cancer (BC) is a long recognized risk factor for developing the disease. Also, there have been some reports of links between an FH and some other malignancies (mostly uterus, ovary, and prostate cancers), and an increased risk of developing BC. In this paper we present descriptive report of the occurrence pattern of malignancies in families of BC afflicted patients through 4 generations. Patients included 542 Iranian primary BC cases, presenting at an outpatient clinic for treatment and follow-up. Detailed pedigrees were drawn for each patient, and data for a total of 6220 relatives were gathered. Among the probands, 29.9% and 53.9% had a positive FH of BC and other malignancies (OM) respectively. Mean number of breast cancers was nearly double in maternal-lines versus paternal-line relatives. Also, occurrence of brain, uterus, and colorectal cancers was significantly higher in maternal-line relatives, but conversely, liver cancer showed a tendency toward paternal-line relatives (1st degree relatives excluded). The highest frequency of BC involvement was noted in 2nd degree/2nd generation, and 3rd degree/3rd generation relatives. For OMs, although gastric cancer was by far the most frequent OM across pedigrees, uterus cancer, and hematopoeitic system lesions (leukemia) predominated over gastric cancer through the 3rd and 4th generations respectively. We did not find any relation between having a positive FH of BC, and developing early-onset BC. The findings discussed in this paper were partially presented at the 18th UICC International Cancer Congress, Oslo-Norway, 30 June-5 July 2002.
