Members of Shc family conventionally serve as critical adaptors in tyrosine phosphorylation signal transduction pathways. p66(Shc) protein, a member of Shc family, is predominantly expressed in epithelial cells, whereas the regulation of its expression remains an enigma. We describe the effect of steroid hormones on the protein level of p66(Shc) and growth stimulation in hormone-sensitive human prostate, testicular and breast cancer cells. In DHT-treated androgen-sensitive prostate cancer LNCaP C-33 cells, the protein level of p66(Shc) was elevated by approximately 3-fold, correlating with increased cell growth. This DHT effect on p66(Shc) protein level and growth regulation was also observed in another androgen-sensitive prostate cancer cell line MDA PCa2b as well as 2 testicular cancer cell lines, Tera-1 and Tera-2 cells. Similarly, the female sex hormone estrogen had a stimulating effect on p66(Shc) protein level and proliferation in estrogen-sensitive MCF-7 breast cancer cells. The upregulation of p66(Shc) protein level by DHT was competitively abolished by Casodex, an androgen antagonist used to treat prostate cancer. Moreover, immunohistochemical analyses showed that the p66(Shc) protein level was significantly higher in primary prostate tumors than in adjacent non-cancerous cells (p < 0.05). The data collectively indicate that p66(Shc) protein levels correlate with steroid hormone-stimulated cell growth and prostate carcinogenesis.

We used the nationwide Swedish Family-Cancer Database to analyse the association of histology-specific brain tumours with other cancers in family members. Among 0-68-year-old offspring, 9414 patients with brain tumours were identified from 1961 to 2000, of whom, 3387 parents were diagnosed with any primary neoplasm. Astrocytoma, meningioma and neurinoma were the main histological types. Increased standardised incidence ratios (SIRs) were found for brain tumours in association with cancers at sites that are known features in recognised syndromes, such as haemangioblastoma and renal cancer in von Hippel-Lindau disease. In addition, an association between astrocytoma and melanoma was recognised. Among as yet unknown clustering, neurinoma was associated with testicular cancer and myeloma; meningioma was associated with cervical cancer; astrocytoma was associated with prostate cancer; ependymoma was associated with breast cancer. Although some of these may feature a true tumour cluster, they need to be confirmed in another setting.

Several studies suggest that cellular adhesion molecules (CAM) play a role in cancer progression and metastasis. To evaluate the role of these molecules as possible tumor markers in patients with urological malignancies, we examined the serum levels of intercellular cell adhesion molecule-1 (ICAM-1), vascular cellcular adhesion molecule-1 (VCAM-1) and E-selectin in patients with renal cell-, bladder-, prostate- and testicular cancer. Serum levels of 237 patients with urological cancers, renal cell carcinoma (n = 47), bladder cancer (n = 81), prostate cancer (n = 87) and testicular cancer (n = 22) and a group of 41 patients with benign prostate hyperplasia (BPH) as well as a 42 healthy control persons were examined for CAMs by specific ELISA tests. Serum CAM concentrations of all tumor patients were compared with controls and within the group according to T stage, N stage, tumor grade and extent of distant metastasis. Our results demonstrate that ICAM-1 and VCAM-1 serum levels are not stage dependently elevated; in contrary, they demonstrate a wide range and are highly variable throughout the different cancer types. In renal cell cancer and in bladder cancer, there is a significant difference for ICAM-1 between controls and T3 and T4 and metastatic cancers. A similar difference was found for VCAM-1, however not for E-selectin in any tumor group. Testicular cancer and prostate cancer did not demonstrate any difference in CAM serum levels between patients with tumors and controls. In metastatic renal cell-, bladder- and prostate cancer, the serum levels of ICAM-1 and VCAM-1 showed a tendency to correlate with the extent of metastatis although no statistical difference between patients with a single metastatic lesion and patients with multiple lesions could be demonstrated. The results of this study implicate a rather limited role of cellular adhesion molecules. Despite of significant ICAM-1 or VCAM-1 serum levels in some locally advanced tumors or metastatic disease, this observation does not provide enough relevant clinical information for use as tumor markers.

Prevention of urologic cancer is a new field for urology. It focuses attention on men and women who may not be under the regular care of physicians and are without symptoms of disease. Although risk factors (eg, smoking in bladder cancer, family history or African-American ethnicity in prostate cancer, cryptorchid testes in testis cancer, Von Hippel-Lindau disease in renal cell carcinoma) can identify individuals at a greater risk for genitourinary malignancies, most patients have no risk factors except gender and age. Thus, developing public health recommendations that will have a major impact on these diseases will be challenging. Prevention strategies will be held to a higher standard of safety than traditional cancer treatment unless populations at a high risk for disease can be identified. It will be necessary for urologists to monitor the field of disease prevention because of the high frequency of urologic malignancies and the growing elderly population in the United States. Urologists are frequently providers for and confidants of this patient population and must be able to counsel these men and women about the benefits and risks of such prevention strategies.

The incidence of Genito-urinary cancer (GUC) in the Kingdom of Saudi Arabia (KSA) increases with age and is 5-fold higher in men than in women. Genito-urinary cancer accounts for only 9.2% of all cancers in KSA, while the rate in the United States of America (USA) is as high as 24.1%. An epidemiological search on GUC in KSA revealed a relatively low incidence compared to developed countries. This is more evident in prostatic cancer, which is 50 times lower than in the USA. The most common GUC in KSA is bladder, followed by the prostate, kidney, and testicular cancer. Penile cancer is extremely rare. Genito-urinary cancer is not among the 10 most common cancer in KSA, however, bladder cancer ranking tenth. Reviewing the National Cancer Registry data in addition to the available literature on GUC in KSA for the past 50-years showed the changing pattern of this disease over time.

This paper compares the portrayal of breast, testicular and prostate cancer in mass print English language magazines in the United States and Canada from 1996 to 2001. It is a follow-up of three papers that examined each of these three diseases separately in high circulating magazines up to 1995. It includes both quantitative and qualitative analyses of magazine stories and notes the continuing dominance of a medical perspective regarding disease as well as the association of each type of cancer examined with stereotypically individualized yet feminine and masculine characteristics and pursuits. It notes the conflation of breast cancer, since the discovery of BRCA1 and BRCA2, with the family. To be a 'feminine' woman is to be vulnerable to breast cancer and to be a 'masculine' man is to be vulnerable to testicular cancer when young and prostate cancer when older. The association of disease not just with personhood but also with the specifics of stereotyped masculinity and femininity may construct a more intimate, more personal link between disease and identity. This close attachment of gender and disease may shore up and exacerbate a fear reaction. It may also serve to diminish the awareness of other, more prevalent, causes of death for men and women. The social control consequences of potentially exacerbated disease-specific fear are discussed.

Cancer is a disease that most people fear. Nurses are required to provide information on how to avoid cancer, and, once the diagnosis is made, how to cope with it. Prevention and early detection of the cancers described in this article are in the very early stages of knowledge development, but general health promotion guidance can be offered on how to avoid most cancers (ie, no tobacco use, a high-fiber and low fat diet, exercise, and maintaining a normal weight). Nurses also can advise patients to be screened for colorectal cancer at the appropriate ages and time intervals and to be aware as new developments occur in the scientific base for screenings in the areas of prostate, penile, and testicular cancer. Finally, coping with these forms of cancer often requires the patient to make major lifestyle and psychological changes, especially if surgery in the genital area occurs. Decreased libido, incontinence, and impotence are major complications that can occur with these illnesses. The male cancers described vary tremendously in their prevalence, incidence, mortality, treatment, and survival rates. Within this group, there are remarkably positive outcomes and outcomes much in need of improvement. Penile and testicular cancers are the bright spots in this picture; both are uncommon, and both are eminently treatable. Prostate cancer, on the other hand, is quite common, difficult to screen, difficult to treat without major sexual problems, and yet receives relatively little funding from the NIH. Although as many men die from prostate cancer as women die from breast cancer, NIH funds breast cancer research at much higher levels than prostate cancer. According to the latest data available at the NIH Web site, during the 1990s, the amount of NIH funding varied from four times more for breast cancer (1993) to 2.9 times more in 1999. For fiscal year 2002, NIH is providing $522 million in funding for breast cancer and $278 million for prostate cancer. Private foundation funds for prostate cancer are much smaller than those available for breast cancer. Both types of cancer are extremely important to address, and both should receive adequate research attention. Nurses can advocate for more funding for prostate cancer, from basic science approaches to behavioral science strategies.

Diethylstilbestrol is a synthetic nonsteroidal estrogen that was used to prevent miscarriage and other pregnancy complications between 1938 and 1971 in the United States. In 1971, the U.S. Food and Drug Administration issued a warning about the use of diethylstilbestrol during pregnancy after a relationship between exposure to this synthetic estrogen and the development of clear cell adenocarcinoma of the vagina and cervix was found in young women whose mothers had taken diethylstilbestrol while they were pregnant. Although diethylstilbestrol has not been given to pregnant women in the United States for more than 30 years, its effects continue to be seen. Women who took diethylstilbestrol during pregnancy have a slightly higher risk of breast cancer than the general population and therefore should be encouraged to have regular mammography. Women who were exposed to diethylstilbestrol in utero may have structural reproductive tract anomalies, an increased infertility rate, and poor pregnancy outcomes. However, the majority of these women have been able to deliver successfully. Recommendations for gynecologic examinations include vaginal and cervical digital palpation, which may provide the only evidence of clear cell adenocarcinoma. Initial colposcopic examination should be considered; if the findings are abnormal, colposcopy should be repeated annually. If the initial colposcopic examination is normal, annual cervical and vaginal cytology is recommended. Because of the higher risk of spontaneous abortion, ectopic pregnancy, and preterm delivery, obstetric consultation may be required for pregnant women who had in utero diethylstilbestrol exposure. The male offspring of women who took diethylstilbestrol during pregnancy have an increased incidence of genital abnormalities and a possibly increased risk of prostate and testicular cancer. Routine prostate cancer screening and testicular self-examination should be encouraged.

The two-week-wait cancer initiative in the UK was designed to speed referral of patients suspected of having cancer and, by so doing, improve their outcome. We reviewed the case notes of all patients referred under this scheme to a single urology department over twelve months. In the department, nearly one-third of new outpatient appointments came under this scheme. 124 patients were referred and all but 7 were seen within the 14-day deadline. In 62 the reason for referral was haematuria, which was macroscopic in 42. Of those with macroscopic haematuria 6 proved to have cancer, newly diagnosed in 4 (2 bladder, 2 renal); no patient with microscopic haematuria had cancer. Of 35 referred with a raised prostate-specific antigen 11 had prostate cancer, in most cases beyond cure. Cancer was found in 1 of 19 patients referred with a testicular mass. In patients referred under the two-week-wait scheme with macroscopic haematuria, cancer is common. Microscopic haematuria is seldom significant. Carcinoma of the prostate is usually advanced and beyond cure at presentation. Among patients referred with scrotal lumps, cancer of the testis is not common. The scheme as a whole is unlikely to improve cancer outcomes. Patients with macroscopic haematuria might be better served by one-stop clinics. For those with testicular lumps, most of which will be benign, the best answer might be direct general practitioner access to scrotal ultrasonography.

Similarly as in other developed countries of the world cancers of the upper and lower urinary tract are increasing also in Slovakia. Of greater importance are urological cancers in men participating recently worldwide with 17% on all newly diagnosed cancers. In women only 3% of all incident cases occur in urological sites. Data on incidence of urological cancers in the period 1968-1999 were derived from the National Cancer Registry, while those of mortality from the Statistical Office of the Slovak Republic. World standard population was used for the age-adjustment of both indicators. Temporal trends were evaluated using Poisson regression and computation of mean annual percent changes (MACP). Substantial and nearly parallel increase of incidence and of mortality has been observed for prostate cancer. Despite dramatic increase of testicular cancers incidence, corresponding mortality rates remained stable with the tendency to decrease recently. Incidence and mortality rates of urinary bladder cancer in men showed tendency to peaking while in women incidence increased and mortality showed tendency to stabilization. Incidence rates of kidney cancers increased in both sexes during the whole period, followed by slow increase of mortality at substantially lower levels. With the exception of mortality from testicular cancer all analyzed trends were statistically significant. In conclusion, only in the case of testicular cancer important reduction of mortality has been obtained despite dramatic increase of incidence. Reduction of smoking and improvement of industrial hygiene may influence the development of bladder cancer incidence and mortality. Limited resources for establishment of a concise cancer control program in this country do not allow to slow down in the near future the increase of incidence and mortality of prostate and kidneys cancers in Slovakia.
