The initial site of disease relapse was identified for 79 patients with metastatic renal cell cancer (RCC), melanoma, colon cancer, or non-Hodgkin's lymphoma (NHL), who had achieved partial or complete responses to one of five IL-2-based immunotherapy regimens. The initial site of relapse was evenly distributed between pre-existing sites of disease (33%), new sites of disease (38%), or both (29%). There was no difference in the distribution of recurrences between patients with partial or complete responses. Fifty-one patients with prior complete or partial responses were retreated with additional IL-2-based therapy following tumor progression. Five of 51 patients retreated following relapse developed new partial responses. There were no complete responses. Three patients with NHL were retreated with IL-2 and LAK cells and all achieved a second response, while only 2 of 48 patients with other histologic diagnoses reresponded. It is concluded that after a partial or complete response to IL-2-based immunotherapy, patients who relapse do so equally at new and pre-existing sites of disease. A response to retreatment following tumor progression may be attained in patients with NHL, while a new response is unlikely for patients with melanoma and RCC.

Ten patients with non-Hodgkin's lymphoma originated in the nasal cavity (four patients) and in the paranasal sinuses (six patients) were treated mainly with irradiation and combination chemotherapy including adriamycin. According to the TNM AJC staging system, four patients were in stage T1-T2, and six patients were in stage T3-T4. Nine patients, other than one with stage IV (Ann Arbor) disease, achieved complete remission. Death due to lymphoma occurred in four patients, 4 to 39 months following diagnosis. Three of these patients developed systemic extranodal dissemination, and died in a short time after relapse. Death due to second malignancies occurred in two patients. One died of acute myelogenous leukemia, and the other died of colon cancer, 26 and 53 months after diagnosis, respectively. Four patients were alive and disease-free, from 23 to 68 months following diagnosis (median 40 months). Out of four patients who died of disease, three were in stage T3-T4, and one was in stage T1. Two patients with stage T1 originated in the nasal cavity were both alive and disease-free. Except for lymphomas with stage T1 originated in the nasal cavity, more intensive chemotherapy should be instituted in an attempt to achieve better disease-free survival.

The causes of mortality of 3,649 white and 397 non-white male U.S. embalmers and funeral directors, who had died between 1975 and 1985, were examined in a proportional mortality study. Non-significant excesses were found for malignancies of the buccal cavity and pharynx (PMR = 120) and for nasopharyngeal cancer (PMR = 216). No sinonasal cancers were observed, while 1.7 were expected. A statistically significant excess of colon cancer (PMR = 127) was found and a non-significant excess of brain and other CNS cancer was noted among whites only (PMR = 123). Statistically significant excesses of malignancies of the lymphatic and hematopoietic systems were found in whites (PMR = 131) and non-whites (PMR = 241). Myeloid leukemia (PMR = 157) and leukemia of other and unspecified cell types (PMR = 228) were in excess, while no excess of lymphatic leukemia was noted. Elevations in risk were also found for non-Hodgkin's lymphoma, polycythemia vera, and myelofibrosis. Non-whites showed a marked excess of multiple myeloma (PMR = 369). Chronic nephritis was in excess among whites (PMR = 215) and non-whites (PMR = 257). No excess of cirrhosis of the liver was found. Excesses of malignancies of the lymphatic and hematopoietic systems could not be directly related to job held in the funeral industry. Further case-control studies are planned to rule out the possibility that the observed associations are artifactual, by assessing the association between specific work practices and disease risk.

The mortality of forest conservationists and soil conservationists in the United States Department of Agriculture (USDA) who died during January 1, 1970-December 31, 1979 (N = 1,411 white males) while actively employed or while receiving a pension was evaluated. The proportionate mortality analysis was used to identify cancers that might be elevated in this occupational group compared to the total U.S. white male population, whereas case-control analyses more rigorously evaluated the disease association with occupation. Controls were selected from employees at USDA who died of any cause of death other than that cause of death represented by the case. In case-control analyses, non-Hodgkin's lymphoma (NHL) and colon cancer demonstrated a statistically significant linear trend (p less than .05) with duration of employment as either a forest or soil conservationist, which suggests an occupational etiology for both diseases. Soil conservationists who were last employed after 1960 experienced significantly elevated risks for NHL (OR = 2.6) and colon cancer (OR = 1.8), whereas those last employed before 1960 were not at an increased risk. Among forest conservationists, the risk for both NHL and colon cancer appeared to be elevated before and after 1960.

The association between farming occupations and the incidence of non-Hodgkin's lymphoma (NHL) was examined in a case-control study using a cancer registry to identify cases and controls and death certificates to determine the occupation and industry of employment of cancer patients. Case subjects were white males with a diagnosis of NHL who died between 1967 and 1982; control subjects were white males who died of colon cancer during the same period. Control and case subjects were frequency-matched for age and year of diagnosis; county of residence was not a matching variable. Death certificates with codable occupational information were located for 90% of the 249 case and 293 control subjects. A stratified analysis using test-based confidence intervals revealed an increased risk of NHL among farmers. The overall odds ratio, controlling for age and for year of diagnosis, was 1.3 (90% confidence limits 0.9-2.3). For diagnoses during 1952 through 1965, the odds ratio was 6.6, and for diagnoses during 1966 through 1971, the odds ratio was 3.1. The increased odds ratio was most pronounced among those aged 45 to 64 years at the time of diagnosis and those living in rural counties.

The risk of a second primary cancer developing was evaluated in nearly 20,000 men with cancers of the prostate or testis in Connecticut, 1935-82. Among 18,135 men with prostate cancer, a significant 15% deficit of all second cancers was observed [1,053 vs. 1,241; relative risk (RR) = 0.85; 95% CI = 0.80-0.90], most notably for respiratory (RR = 0.7) and digestive cancers (RR = 0.8). The absence of a colon cancer risk lends little support to the idea of common risk factors such as dietary fat consumption. Only the risk for salivary gland cancer was significantly increased, possibly due to chance. Leukemia was significantly elevated among men observed for 10 and more years (RR = 2.2). In contrast to most other index tumors, the prostate stands out as being associated with an overall low risk of second cancer development. The reasons for these deficiencies have not been explained. Among 1,446 men with testis cancer, a significant twofold risk of second cancers was seen (104 vs. 50.1). A fivefold risk of leukemia (8 vs. 1.5) was not related to treatment or age. Contralateral testis cancer (6 vs. 0.5) was elevated in men treated with and without radiation. Risks for kidney cancer (5 vs. 1.5), bladder cancer (9 vs. 3.4), pancreatic cancer (6 vs. 1.5), non-Hodgkin's lymphoma (6 vs. 1.5), and prostate cancer (12 vs. 5.9) were significantly increased. No trends over time were noted for any cancer. Overall risk of second cancer development tended to be higher in younger men with testis cancer. The relationship of leukemia to testis and prostate cancers should be investigated in future research.

Among 41,109 women diagnosed with breast cancer between 1935 and 1982 in Connecticut, 3,984 developed a second cancer, whereas 2,426 were expected [relative risk (RR) = 1.64; 95% CI = 1.6-1.7]. This increased risk persisted for 30 years and was highest in women under 55 years of age at the time of breast cancer diagnosis. Second primary breast cancers (RR = 3.0) accounted for almost one-half of all new neoplasms. However, if subsequent breast cancers were excluded, the risk for all other second cancers was only 1.15 (95% CI = 1.10-1.20), and no excess risk was seen among women over age 55 at initial breast cancer. Significant risks were found for cancers of the ovary (RR = 1.7) and uterine corpus (RR = 1.4), possibly linked with shared reproductive factors such as nulliparity or late age at menopause. Malignant melanoma (RR = 1.5), thyroid cancer (RR = 1.6), and colon cancer (RR = 1.2) were also significantly elevated; possible shared risk factors remain to be elucidated. Significant deficits of multiple myeloma and chronic lymphocytic leukemia were noted. Women who received initial radiotherapy compared with those who did not were at slightly higher risk of developing a second cancer, most notably acute nonlymphocytic leukemia, non-Hodgkin's lymphoma, and cancers of the esophagus, kidney, and connective tissue, although the nature of the associations was not always clear. Some of the soft tissue sarcomas were lymphangiosarcomas of the arm, a consequence of the lymphedema that may complicate radical mastectomy (Stewart-Treves syndrome). Women treated with radiation were at higher risk of developing a second breast neoplasm (RR = 3.9) than nonirradiated women (RR = 2.8). Further investigation should focus on the mechanisms underlying the relationships between breast, genital tract, and colon cancers, and on the effects of treatment modalities on the risk of subsequent neoplasms.

Incidence of second primary cancers was evaluated in 7,127 women with invasive cancer of the cervix uteri, diagnosed between 1935 and 1978, and followed up to 38 years (average, 8.9 yr) in Connecticut. Among 5,997 women treated with radiation, 449 developed second primary cancers compared with 313 expected (relative risk = 1.4) on the basis of rates from the Connecticut Tumor Registry. Excess incidence was noticeable 15 years or more after radiotherapy and attributed mostly to cancers of sites in or near the radiation field, especially the bladder, kidneys, rectum, corpus uteri, and ovaries. No excess was found for these sites among the 1,130 nonirradiated women. The ratio of observed to expected cancers for these sites did not vary appreciably by age at irradiation. The data suggested that high-dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but, apparently, not leukemia, Hodgkin's disease, breast cancer, or colon cancer.

To evaluate the patterns of mesenteric disease as visualized by computed tomography (CT), we reviewed the scans of 370 patients whose primary diagnoses coincided with diseases known from the pathology literature to have frequent mesenteric involvement. Diagnoses included selected malignancies, inflammatory diseases, and traumatic injuries. Four general patterns of involvement of the mesentery were recognized: (a) rounded masses, (b) "cake-like" masses, (c) ill-defined masses, and (d) stellate mesentery. Of the malignancies reviewed, mesenteric involvement as visualized by CT occurred most commonly with ovarian carcinoma (20/52) and non-Hodgkin's lymphoma (41/134). The incidences of CT evidence of involvement of the mesentery with other common malignancies were carcinoma of the colon (8/68), carcinoma of the pancreas (5/21), and leukemia (5/19). Certain benign and malignant lesions of the mesentery do demonstrate unique CT patterns of involvement. Examples of the individual patterns in common and unusual disease states are illustrated.

Several Louisiana parishes (counties) using the Mississippi River for their source of public drinking water have the highest mortality rates (1950-69) in the United States for several cancers. Therefore, a case-control mortality study on cancer of the liver, brain, pancreas, bladder, kidney, prostate, rectum, colon, esophagus, stomach, non-Hodgkin's lymphoma, multiple myeloma, leukemia, Hodgkin's disease, lung; breast and malignant melanoma, from 1960 to 1975 in South Louisiana parishes grouped for similarities in industrial characteristics, having approximately equal exposure of the population to surface and groundwater, was conducted. Noncancer deaths were randomly selected as controls and matched to the case death on age, race, sex, and year and parish group of death. Water source at death was assigned based on the residence at death and described as surface or ground and chlorinated or nonchlorinated. A significantly increased risk for surface, chlorinated water use was noted for rectal cancer. No risk could be demonstrated for colon cancer. The risk noted for bladder cancer by other investigators is not substantiated. Brain cancer risk appears to be associated with chlorinated groundwater, but this may be industrial confounding. Breast cancer demonstrated a slight, but significant, risk associated with surface chlorinated water. This risk, however, might be due to confounding of rural life style, early childbearing and large families with nonchlorinated water found in these settings. Chlorination risk for kidney cancer was not significant. No risk was observed in association with surface water for other cancers of the gastrointestinal or urinary tract. Multiple myeloma was significantly associated with a risk from ground water.
