A case of metastatic thyroid cancer from sigmoid colon cancer is presented. A 52-year-old woman had a sigmoidectomy due to adenocarcinoma of the sigmoid colon in April 1988. Serum carcinoembryonic antigen (CEA) levels gradually rose from July 1990 along with multiple metastatic lesions which appeared in the lung. They were resected in January 1991. Two months later the subject noticed a painless and firm lump on the left anterior neck. She was found to have a solitary mass in the left thyroid lobe. Thyroid function remained within normal range. Cytological findings obtained by fine-needle aspiration biopsy showed tall columnar carcinoma cells with an acinar pattern. Subtotal thyroidectomy was performed, and histological examination revealed metastatic adenocarcinoma from colon cancer. Immunohistochemical staining by anti-CEA was positive but anti-thyroglobulin was negative.

Thirty-seven patients with tracheobronchial lesions by malignant tumor were treated with Nd-YAG laser. Thirty-seven patients were twenty-three males and fourteen females and ages ranged from 34 to 79 years. Diseases included were primary tracheal tumor in 3 cases, lung cancer in 16 (8 squamous cell carcinoma, 5 adenocarcinoma, 2 large cell carcinoma, 1 small cell carcinoma), cancer of adjacent organs in 9 (5 thyroid cancers, 4 esophageal cancers), and metastatic cancer to the lung or mediastinal lymph nodes in 9 (4 renal cell carcinoma, 2 thyroid cancer, one patient respectively, colon cancer and breast cancer). Intermittent irradiation of YAG laser was done for 0.5 second at 30-40 Watt through flexible bronchoscope under local anesthesia. It was repeated 1 to 41 times (mean 4.1 times) and energy amount was 148 Joules to 18,513 Joules (mean 3,305 J). The result was; stenosis disappeared in 22 cases (59.4%), improved in 14 (37.8%), and in one case YAG laser therapy discontinued due to intractable bleeding. The Nd-YAG laser therapy for tracheobronchial lesions by malignant tumor is very useful to improve dyspnea or atelectasis.

Plasma lipid-bound sialic acid (LSA) was assayed in normal volunteers, patients with non-malignant diseases, and a variety of cancer patients. Mean plasma LSA in 50 normal volunteers, 16 patients with non-malignant diseases, 54 breast cancer, 17 lung cancer, 15 colon cancer, 7 ovarian cancer, 5 prostate cancer, 4 leukemia, 4 gastrointestinal, 3 thyroid cancer, 3 pancreas cancer and 2 adrenal cancer patients were 17.7, 23.2, 58, 85, 56.7, 46.2, 56.7, 53.3, 31.1, 33.2 and 119.5 mg/dl, respectively. None of the normal volunteers had elevated plasma LSA values. Plasma LSA level was not significantly different in male and female volunteers. Two out of 114 different cancer patients had plasma LSA levels within normal range exhibiting 98.2% sensitivity of the assay. Plasma LSA, which is relatively simple to assay, may be used as a tumor marker in wide variety of neoplastic diseases.

A case of a surgically treated primary quartet cancer is reported, along with a review of the Japanese literature. A 68-year-old woman, curatively operated for a right breast cancer 6 years previously, was then diagnosed as having a left renal cell carcinoma, a thyroid cancer, and a sigmoid colon cancer as a result of a subsequent screening examination within one year. These synchronous, triple cancers were resected in a curative operation for each. Histopathologically, each neoplasm was proven to be a primary cancer lesion, and two different types (papillary and trabecular) were found in the thyroid gland.

Cholesterolaemia values have been investigated in a simple of colon cancer patients and in two control samples consisting of age and sex corresponding subjects suffering respectively from peripheral arteriopathy and minor pathologies (hernias and varices). The study was extended subsequently to a sample of subjects suffering from thyroid neoplasia and two similarly constituted control samples. Cholesterolaemia was significantly lower in colon cancer patients than in the control samples whereas in subjects suffering from thyroid cancer, statistical significance was not attained even though a similar reduction was recorded. The reduction in cholesterol in cancer patients is, in the light of the most recent studies, an effect of cancer on cholesterolaemia, thus giving the lie to the theory that low blood cholesterol is a factor favouring the onset of cancer, and is a finding with by no means indifferent repercussions on the study of the behaviour and physiopathology of cancers.

Cancer incidence rates were compared for Filipinos in Hawaii (1978-81) and Manila (1977). Data for Hawaii were from the statewide Hawaii Tumor Registry; those for Manila were from the Central Tumor Registry of the Philippines. In addition, time trends (4-yr intervals) for cancer among Filipinos in Hawaii were examined for the period 1962-81 and compared with corresponding patterns among Caucasians. For most cancer sites, the rates among Filipinos in Hawaii showed expected increases or decreases from the Manila rates. Notable findings included a dramatic increase in thyroid cancer rates among Filipino women in Hawaii (highest of all ethnic groups), a surprising lack of increase in female breast cancer rates in Hawaii, and a lower than expected increase in colon cancer rates in Hawaii. The time trend analyses showed remarkably similar patterns in Filipinos and Caucasians in Hawaii and no suggestion that differences between the 2 populations are decreasing over time. These observations indicate that useful clues to cancer etiology can be found by further study of the Filipino experience in Hawaii.

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.

As an extension of the previous finding that radioactivity of 14C-labeled D-amino acids after injection is localized preferentially in the tumor and the pancreas of tumor-bearing animals as compared with the corresponding L-amino acids tested, the results of similar uptake experiments using other tumors araa reported here. The present studies show high radioactivity uptake by human colon cancer, human thyroid cancer, and human leiomyosarcoma transplanted into nude mice, and by solid leukemia L1210 and solid sarcoma 180, but not by Morris hepatoma 7316A or 3'-methyl-4-(dimethylamino)azobenzene-induced rat hepatoma. The results suggest the potential utility of 11C-labeled D-amino acids for the detection of some cancers.

201Tl accumulates well in the malignant tumors. Since high uptake ratio of tumor to blood can be obtained soon after injection, a small lesion can be detected by SPECT imaging. It has been observed that 201Tl imaging is useful to detect recurrent lesions or metastatic lesions from thyroid cancer, lung cancer, brain tumor, breast cancer, mediastinal tumor, bone and soft tissue tumor, pancreas cancer and colon cancer. The clinical application of 201Tl is expected to expand. Although 201Tl accumulates in benign lesions, the accumulation in malignant lesions retained more longer than in benign lesions. This unique characteristic is useful to separate benign from malignant lesions. 201Tl is expected useful for evaluating response of tumor to radiation therapy and/or chemotherapy as 201Tl accumulates in viable tumor cells.

Preparation with enzymes plays an important part in obtaining good results in cellular DNA content measurements from paraffin-embedded tissue using flow cytometry. Therefore, we have compared two groups of DNA histograms obtained with pepsin (Hedley method) and trypsin digestion (Schutte method). Samples of five tumor types were compared: eight lung, seven breast, five thyroid, seven stomach, and six colon cancer cases. All samples were stained with propidium iodide (PI). The incidence of DNA aneuploidy determined by the Schutte method indicated a higher ratio in four tumor types than that determined by the Hedley method. Concerning the coefficient of variation (CV) used to estimate the quality of the DNA histogram, the diploid G1 peak determined by the Schutte method produced a smaller CV in five tumor types than did the Hedley method. This Schutte method had especially good results in lung and thyroid cancer. Furthermore, the amount of debris (background) determined by the Schutte method indicated a decrease in four tumor types compared with the Hedley method. In cell-cycle analysis of ten DNA diploid cases, DNA histograms by the Hedley method showed an increased S-phase fraction due to an overlapping of debris and aggregated cells. These results indicate that preparation by trypsin digestion is a method superior to pepsin digestion when the sample from paraffin-embedded tissue is stained with PI for the purpose of DNA content measurement.
