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.

Monoclonal antibodies to keratin, vimentin, leukocyte common antigen (LCA) and S-100 protein have been used in fine needle aspirates of 35 metastatic malignant melanomas, 136 carcinomas, 35 sarcomas and 82 non-Hodgkin's lymphomas in search for immunocytochemical criteria useful in differential diagnosis of melanoma versus carcinoma, non-Hodgkin's lymphoma and sarcoma. All melanomas expressed vimentin and did not express keratin. Six of 14 melanomas contained S-100 protein. All carcinomas were keratin positive. Some were also vimentin positive. All sarcomas expressed vimentin. Synovial sarcomas were also keratin positive. All NHLs were vimentin positive, keratin negative. All NHLs except one expressed also LCA. It is concluded that keratin, vimentin and LCA are useful markers in differential diagnosis of malignant melanoma versus carcinoma and non-Hodgkin's lymphoma in fine needle aspirates when used together with morphologic and clinical data. However, in differential diagnosis of malignant melanoma and sarcoma these markers are of little use.

A monoclonal antibody (Ki-M6) against the CD 68 antigen, which labels cells of the monocyte/macrophage system, was tested on Bouin-fixed, paraffin-embedded samples of normal, reactive and neoplastic tissues by an avidin-biotin-peroxidase complex method, with the aim of establishing its value in diagnostic pathology. In normal human tissues, Ki-M6 reactivity was confined to the so-called resident macrophages populating normal organs under physiological conditions. Moreover, restricted reactivity against cells of macrophage lineage was observed in reactive and inflammatory lesions. Granulocytes, monocyte/macrophage-related immune accessory cells, and other analysed normal tissue structures did not reveal any reactivity. Ki-M6 was strongly reactive with the cases of benign (4/4) and malignant (15/15) fibrous histiocytomas, in addition to the true histiocytic lymphomas (3/3). Cases of granular cell tumour (2/3) showed strong reactivity with Ki-M6, whereas only few immunoreactive cells, with weak staining, were seen in the other Ki-M6-positive neoplasms [neurofibroma (3/3), benign schwannoma (1/2), ganglioneuroma (1/1), malignant schwannoma (5/9), melanoma (9/28), dermatofibrosarcoma protuberans (1/1), myelomonocytic leukaemia (3/3)]. Among the epithelial malignancies tested (47 cases), Ki-M6 was positive only in renal cell carcinoma (11/14). Malignant lymphomas of the Hodgkin (56 cases) and non-Hodgkin type (67 cases) were uniformly non-reactive. From these data, Ki-M6 appears to be an excellent marker of monocyte/macrophage-related cells and appears to be a reliable indicator for fibrous histiocytomas and true histiocytic malignancies. The availability of this additional antibody capable of staining routinely processed tissue is of practical interest.

Interleukin-2 (IL-2) plus lymphokine-activated killer (LAK) cell therapy has antineoplastic activity in renal cancer and malignant melanoma. In order to explore the activity of this therapy in Hodgkin's disease and non-Hodgkin's lymphoma, the Extramural IL-2/LAK Working Group (ILWG) treated 27 patients on two protocols using high-dose IL-2 and autologous LAK cells. Two of 12 patients with Hodgkin's disease experienced partial responses lasting 6 and 12 weeks. No patient with non-Hodgkin's lymphoma responded (p = NS). The toxicities of therapy were similar to those reported by the ILWG from trials of IL-2/LAK in solid tumors, consisting of transient hemodynamic, cardiopulmonary, renal and hepatic dysfunction, skin rash, fever, and flu-like symptoms. In view of the low response rate and the brief duration of these responses, we do not recommend the regimens reported here for further investigation in Hodgkin's disease or non-Hodgkin's lymphomas.

A probe, recombinant antistasin, that reacts specifically with the activated form of factor X (Xa) was used in immunohistochemical procedures to detect cellular sites of Xa generation within intact tissues. Factor Xa was detected on tumor cells in small cell carcinoma of the lung, renal cell carcinoma, and malignant melanoma. Tumor-associated macrophages (but not tumor cells) expressed Xa in adenocarcinoma and squamous cell carcinoma of the lung, and Hodgkin's disease. Factor Xa in these locations corresponded to evidence reported previously for an intact coagulation pathway and thrombin formation associated with these tumor cells and macrophages. By contrast, only rare connective tissue cells stained for Xa in breast and colon cancer, tumor types shown previously to lack an intratumoral coagulation pathway and thrombin generation, and in normal liver, lung, breast, kidney, and placental tissues. Hepatocytes did not stain. These results suggest that such probes may be useful for studying the activation state of cell-associated factor X in situ within intact tissues.

This paper reports incidence of cancer in employees of the Australian petroleum industry from 1981 to 1989. Two surveys by personal interview incorporated more than 15,000 employees, representing 92% of the eligible population. Subjects were included in the analysis after completing five years of service in the industry. At the time of this report the cohort did not include sufficiently large numbers of women for useful analysis; results presented are restricted to the men. On 31 December 1989, 50,254 person-years of observation had accumulated in the men with 152 incident cancers reported. The standardised incidence ratio (SIR) analysis showed overall cancer rates close to those of the national population. Whereas deficits were seen in some cancer sites, notably lung cancer (SIR 0.5, 95% confidence internal (95% CI) 0.3-0.9), incidence rates for some other cancer sites suggested increased risk. An excess of observed over expected cases was present in all subcategories of lymphohaematopoietic cancer except Hodgkin's disease (no cases), and was most apparent in myeloid leukaemia (SIR 4.0, 95% CI 1.6-8.2). The other major site with a raised number of cases observed over expected was melanoma (SIR 1.4, 95% CI 0.8-2.1).

Magnetic resonance imaging (MRI) demonstrates surface anatomy, nerves, and soft tissue pathology. Selective placement of the cursor lines in MRI displays specific anatomy. The MR images can then be used as adjunct in teaching surface anatomy to medical students and to other health professionals. Because the normal surface anatomy could be imaged at UCLA's radiology department, it was decided to image soft tissue abnormalities with MR to assist in patient care. Patients imaged were scheduled for special procedures of the chest or staging lymphangiograms. Patients were placed into categories depending on known diagnosis or interesting clinical presentation. The diagnostic categories included Hodgkin's disease, melanoma, carcinomas (eg, lung or breast), lymphedema, sarcomas, dermatological disorders, and neurological disorders. All images were orchestrated by the radiologist. This article discusses both the teaching and clinical impact on patient care.

Different immunotherapy regimens using s.c. recombinant interleukin-2 (rIL-2) were studied in 76 patients with progressive metastatic renal carcinoma, malignant melanoma, colorectal cancer, B-cell lymphoma, or Hodgkin's disease. To assess the immunomodulatory capacity of rIL-2, we measured serum levels of soluble interleukin-2 (sIL-2) receptors, gamma-interferon, tumor necrosis factor-alpha, and various lymphocyte subsets expressing the CD25 Tac IL-2 receptor and the CD56 natural killer (NK) associated antigen. Additionally, we measured serum antibodies specific to rIL-2 in order to evaluate immunogenicity of rIL-2. In all patients, a significant increase in sIL-2 receptor levels could be observed when comparing values on day 0 and after one treatment course. Patients developing a neutralizing anti-rIL-2 antibody exhibited significantly lower serum sIL-2 receptor levels than patients without antibody. Soluble IL-2 receptors correlated with the percentage of CD25 IL-2 receptor-positive peripheral blood lymphocytes. Both soluble and cell surface IL-2 receptors exhibited a significant increase during rIL-2 therapy but did not correlate with the percentage of CD56-positive peripheral blood lymphocytes. Measurement of treatment-induced secondary cytokines showed significant increases in gamma-interferon serum levels in a proportion of patients tested, although with considerable interindividual variability. No significant increase in mean tumor necrosis factor-alpha levels was observed during rIL-2 treatment in vivo. The percentage of CD56-positive NK cells correlated with the clinical outcome of rIL-2 therapy. Thus, partial or complete responders had an increase from a mean of 20% NK cells prior to therapy up to a mean of 40% after the first treatment course. In contrast, patients with progressive disease had a mean of 22 and 24% NK cells before and after treatment, respectively.

Age-specific worldwide trends in cancer mortality were reviewed, with emphasis on cancer sites where increases have been reported in the USA. Cancer rates vary by factors as high as 30 between all countries, and 5-fold within and between industrialised countries. In Italy, Japan, Federal Republic of Germany, England and Wales, and the USA, patterns of cancer mortality have shifted uniformly over the past two decades. Stomach cancer continues to decline, while brain and other central-nervous-system cancer, breast cancer, multiple myeloma, kidney cancer, non-Hodgkin lymphoma, and melanoma have increased in persons aged 55 and older. Cancer of the lung is starting to decline for men under age 85 and women under age 60 in England and Wales and men under age 45 in the USA, but is still rising for men and women in other countries. All forms of cancer are increasing in persons over age 54 except lung and stomach (which together comprise between 20% and 43% of all cancer in males in these countries). Studies of the quality of ascertainment and enumeration indicate that these increases are not attributable solely to diagnostic artifacts or to increased access to health care, although both these factors may be involved. These recorded increases in cancer should be assessed in greater detail to provide better projections of health care needs and to identify causal factors that may be controlled. The changes in cancer other than lung are so great and rapid that their causes demand intensive investigation.

Special aspects of the localization and spontaneous regression of primaries of malignant melanoma, further more aspects of the pTNM-system as well as problems concerning perfusion therapy are pointed out and discussed. In the following the different biology of squamous cell and basal cell cancer dependent also on the localization of the primaries is described and discussed. Concerning the soft tissue tumor part immunohistochemical methods for the management of differential diagnosis are demonstrated and evaluated. These methods can be used for the delineation of extranodal Hodgkin and non-Hodgkin lymphoma infiltration from soft tissue tumors and in the differential diagnosis of polymorphous, spindle cell and epitheloid differentiated soft tissue tumors. Finally the problem of tumor grading and new grading systems (score) according to Coindre et al. are demonstrated and discussed.
