Cancer is the second cause of mortality in Chile: 12,000 deaths and 27,000 admissions were registered during 1982. Gastric and pulmonary cancer account for the highest mortality rates (23.2 and 9.7/100,000). Cancer prognosis has improved in thyroid, uterus and testes cancers, melanoma, Hodgkin's Disease etc, with 67 to 92% 5-year survival rates, while results are not as good in lung, gastric, colorectal, kidney, pancreas, etc, with only 3 to 52% 5-year survival rates. Treatment failure is attributed to cellular mutations and early metastases. At present, surgery is less aggressive and is associated to radiotherapy and chemotherapy; megavoltage radiation equipment and the use of radiosensitizers allow double radiation dose; chemotherapy complications are avoided with hematopoietic growth factors. It is possible to improve the prognosis of lung cancer avoiding the use of tobacco and of colorectal cancer reducing fats in the diet of these pts. Early detection and better chemotherapy have improved the prognosis of breast and uterus cancer. With these measures a 20 to 50% reduction in cancer rates is expected in the USA for the year 2000. Their application is urgent in our country.

This paper uses information on occupation and industry routinely collected in a state-based cancer registry to assess potential associations between work place exposures and cancer incidence. Industry-specific proportional cancer incidence ratios (PCIR) were calculated by race and sex for all individuals and for white males with blue-collar occupations. Expected numbers of cancers were derived both from cancers occurring among all occupations and just among blue-collar occupations. This latter analysis was done as a control for differences in the prevalence of life-style habits between blue- and white-collar workers. Increased lung cancer PCIR were seen in most industries previously reported to be associated with lung cancer risk. The effects of socioeconomic status on these results are discussed. Other results include an increased ratio of melanoma in blue-collar white male rubber and plastic product workers, an increased ratio of non-Hodgkin's lymphomas in motor vehicle manufacture workers, and an increased PCIR of chronic lymphocytic leukemia in general construction workers. Uterine cancer was increased in proportion in white females for a number of industries including rubber and plastic product manufacture, apparel manufacture, and electrical equipment manufacture.

To explore the role of DDE, the major and most persistent DDT derivative, in cancer etiology, we examined the association of the 1968 adipose DDE levels of population samples from 22 U.S. states with age-adjusted mortality rates between 1975 and 1994 for multiple myeloma; non-Hodgkin lymphoma (NHL); and cancer of the breast, corpus uteri, liver, and pancreas. Separate analyses were conducted by gender and race. Covariates in the regression models included average per-capita income, percent metropolitan residents, and the population density. Liver cancer mortality increased significantly with adipose DDE levels in both sexes among whites, but not among African Americans. No association was observed for pancreatic cancer and multiple myeloma. Breast cancer mortality was inversely correlated with adipose DDE levels among both white and African American women. Significant inverse correlations were also observed for uterine cancer among white women, whereas no association was observed for African Americans and for NHL among whites (men and women) and African American women. The results for pancreatic cancer, multiple myeloma, NHL, breast cancer, and uterine cancer did not support the hypothesis of an association with past adipose levels of the DDT derivative DDE. The multivariate analysis confirmed most findings. The association between liver cancer and DDE observed among whites, particularly in view of the occurrence of hepatic neoplasms in laboratory animals exposed to DDT, warrants further investigation.

Nitrate contamination of drinking water may increase cancer risk, because nitrate is endogenously reduced to nitrite and subsequent nitrosation reactions give rise to N-nitroso compounds; these compounds are highly carcinogenic and can act systemically. We analyzed cancer incidence in a cohort of 21,977 Iowa women who were 55-69 years of age at baseline in 1986 and had used the same water supply more than 10 years (87% > 20 years); 16,541 of these women were on a municipal supply, and the remainder used a private well. We assessed nitrate exposure from 1955 through 1988 using public databases for municipal water supplies in Iowa (quartile cutpoints: 0.36, 1.01, and 2.46 mg per liter nitrate-nitrogen). As no individual water consumption data were available, we assigned each woman an average level of exposure calculated on a community basis; no nitrate data were available for women using private wells. Cancer incidence (N = 3,150 cases) from 1986 through 1998 was determined by linkage to the Iowa Cancer Registry. For all cancers, there was no association with increasing nitrate in drinking water, nor were there clear and consistent associations for non-Hodgkin lymphoma; leukemia; melanoma; or cancers of the colon, breast, lung, pancreas, or kidney. There were positive associations for bladder cancer [relative risks (RRs) across nitrate quartiles = 1, 1.69, 1.10, and 2.83] and ovarian cancer (RR = 1, 1.52, 1.81, and 1.84), and inverse associations for uterine cancer (RR = 1, 0.86, 0.86, and 0.55) and rectal cancer (RR = 1, 0.72, 0.95, and 0.47) after adjustment for a variety of cancer risk/protective factors, agents that affect nitrosation (smoking, vitamin C, and vitamin E intake), dietary nitrate, and water source. Similar results were obtained when analyses were restricted to nitrate level in drinking water from 1955 through 1964. The positive association for bladder cancer is consistent with some previous data; the associations for ovarian, uterine, and rectal cancer were unexpected.

Radiation therapy (RT) is commonly used to treat malignant tumors, but it leads to side effects and complications. Postradiation sarcomas developing from a previously irradiated area are especially vicious to deal with, though their occurrence is rare. This article focuses on the clinical manifestations, pathological characteristics, and therapeutic effects concerning postradiation soft tissue sarcomas (PRSTSs). A series of 14 PRSTSs treated between 1979 and 2000 in five hospitals in Japan were analyzed. Their histological types were malignant fibrous histiocytoma (eight cases), extraskeletal osteosarcoma (four cases), fibrosarcoma (one case), and leiomyosarcoma (one case). The primary diagnoses, RT history, latent period, and outcome of treatment were studied retrospectively. The original tumors included uterine cancer (seven cases), breast cancer (four cases), synovial sarcoma (one case), squamous cell carcinoma (one case), and Hodgkin's disease (one case). There were 13 women and 1 man, with ages ranging from 23 to 77 years (mean 58 years) at the time of the appearance of the PRSTS. RT doses ranged from 48 to 91 Gy (mean 62 Gy). The latent period from RT to the occurrence of the PRSTS varied from 4 to 27 years (mean 12.6 years). Altogether, 4 of 13 patients (31%) had recurrence of the sarcoma after resection. Of the 10 patients whose tumors were removed with a wide margin, one had a local recurrence; 3 cases were performed with a marginal margin and all 3 had a local recurrence. One of three who underwent RT and one of five who underwent chemotherapy (CT) responded. Of the 14 patients, 6 (42.9 %) survived continuously disease free, 2 (14.3%) died from other causes, 2 (14.3%) has an unknown outcome, and 4 (28.6 %) died of the disease during the follow-up period of 16-36 months (mean 24 months). The deaths due to other causes included an esophageal cancer and a wound infection. The prognosis of the PRSTS patients was not poor if the tumor could be removed with a wide surgical margin. Because adjuvant therapies including RT and CT had a poor effect on PRSTSs, the primary treatment of PRSTSs should be radical resection with a wide margin.

Uncertainty continues as to whether treatments for ovulation induction are associated with increased risk of cancer. The authors conducted a long-term population-based historical cohort study of parous women. A total of 15,030 women in the Jerusalem Perinatal Study who gave birth in 1974-1976 participated in a postpartum survey. Cancer incidence through 2004 was analyzed using Cox's proportional hazards models, controlling for age and other covariates. Women who used drugs to induce ovulation (n = 567) had increased risks of cancer at any site (multivariate hazard ratio (HR) = 1.36, 95% confidence interval (CI): 1.06, 1.74). An increased risk of uterine cancer was found among women treated with ovulation-inducing agents (HR = 3.39, 95% CI: 1.28, 8.97), specifically clomiphene (HR = 4.56, 95% CI: 1.56, 13.34). No association was noted between use of ovulation-inducing agents and ovarian cancer (age-adjusted HR = 0.61, 95% CI: 0.08, 4.42). Ovulation induction was associated with a borderline-significant increased risk of breast cancer (multivariate HR = 1.42, 95% CI: 0.99, 2.05). Increased risks were also observed for malignant melanoma and non-Hodgkin lymphoma. These associations appeared stronger among women who waited more than 1 year to conceive. Additional follow-up studies assessing these associations by drug type, dosage, and duration are needed.

The objective of this analysis was to evaluate mortality among a cohort of 24,865 capacitor-manufacturing workers exposed to polychlorinated biphenyls (PCBs) at plants in Indiana, Massachusetts, and New York and followed for mortality through 2008. Cumulative PCB exposure was estimated using plant-specific job-exposure matrices. External comparisons to US and state-specific populations used standardized mortality ratios, adjusted for gender, race, age and calendar year. Among long-term workers employed 3 months or longer, within-cohort comparisons used standardized rate ratios and multivariable Poisson regression modeling. Through 2008, more than one million person-years at risk and 8749 deaths were accrued. Among long-term employees, all-cause and all-cancer mortality were not elevated; of the a priori outcomes assessed only melanoma mortality was elevated. Mortality was elevated for some outcomes of a priori interest among subgroups of long-term workers: all cancer, intestinal cancer and amyotrophic lateral sclerosis (women); melanoma (men); melanoma and brain and nervous system cancer (Indiana plant); and melanoma and multiple myeloma (New York plant). Standardized rates of stomach and uterine cancer and multiple myeloma mortality increased with estimated cumulative PCB exposure. Poisson regression modeling showed significant associations with estimated cumulative PCB exposure for prostate and stomach cancer mortality. For other outcomes of a priori interest--rectal, liver, ovarian, breast, and thyroid cancer, non-Hodgkin lymphoma, Alzheimer disease, and Parkinson disease--neither elevated mortality nor positive associations with PCB exposure were observed. Associations between estimated cumulative PCB exposure and stomach, uterine, and prostate cancer and myeloma mortality confirmed our previous positive findings.

Cancer-associated retinopathy (CAR) is a rare autoimmune condition associated with various cancers, causing significant visual impairment. Visual symptoms in CAR may or may not correlate with the extent of systemic disease or its response to chemotherapy, and must be addressed separately from the management of systemic malignancy. Steroids have been the mainstay of CAR therapy. Various immunomodulatory therapies have also been described with varying responses, but the overall visual prognosis remains poor. Rituximab is a monoclonal antibody used in the treatment of non-Hodgkin's B-cell lymphoma and many autoimmune disorders. This case report describes a patient with small cell uterine cancer who initially presented with visual impairment associated with CAR. The patient's deteriorating visual symptoms were successfully halted for an extended, clinically meaningful period with rituximab.

Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively. A total of 340 patients with SSc were evaluated. Twenty-five of the patients had 19 different types of malignancy. Bladder cancer was the most common type of cancer with four patients and was followed by breast cancer with three patients, and cervix cancer and ovarian cancer with two patients each. Other types of cancers such as squamous cell skin cancer, adenocancer with an unknown origin, multiple myeloma, chronic myeloid leukemia, papillary thyroid cancer, larynx cancer, non-small cell lung cancer, follicular type non-Hodgkin lymphoma (NHL), endometrium cancer, colon cancer, uterus cancer, neuroendocrine tumor, glioblastoma multiforme, and soft tissue sarcoma were diagnosed in one patient each. The only cancer type that showed an association with cyclophosphamide dose was bladder carcinoma. Other malignancies did not show a correlation with age, sex, smoking, type and duration of the disease, autoantibodies, organ involvement, and dose and duration of cyclophosphamide therapy. Cancer may develop in any organ in patients with SSc. Continuous screening of the patients during a follow-up period is necessary for the early detection of the tumor development.

Between the years of 2010-2012, it was estimated there were a total of 112,392 new cases of cancers in Thailand, thus, the total age-standardized rate (ASR) per 100,000 is 137.6. In regards to the most prevalent types of cancer in female, breast cancer has the highest ASR, followed by cervical cancer (ASR=14.4); liver and bile duct cancer; colon and rectum cancer; trachea, bronchus and lung cancer; ovarian cancer (ASR=6.0); thyroid cancer; non-Hodgkin lymphoma and uterine cancer (ASR=4.3). The trend of cervical cancer in Thailand is decreasing, one key factor in making this possible was the employment of dual tract strategy (Pap smear and visual inspection with acetic acid [VIA]) by the government in 2005. In the future, the government is also considering integrating human papillomavirus (HPV) vaccination into the national immunization program, which may assist in the prevention of cervical cancer. By studying the statistical data of gynecologic cancer, it will be possible to formulate measures for the prevention, control and treatment of gynecologic cancer. Eventually, it will potentially improve the quality of life (QoL) of patients as well as decrease the mortality rate caused by gynecologic cancer.
