Interferons are currently the most widely used biological response modifiers. They are of high clinical value in haematological malignancies (chronic myelogenous leukaemia, multiple myeloma, non-Hodgkin lymphoma), in solid tumours (malignant melanoma, hypernephroma, pancreas neoplasms, carcinoid tumours, Kaposi's sarcoma, glioma, in ovarium, cervix and bladder carcinoma, and in basalioma) and in infectious diseases (chronic hepatitis B, chronic non-A/non-B hepatitis, chronic delta hepatitis, AIDS, Papova virus and Rhinovirus infections, leishmaniasis, leprosy) and some other conditions. Although the mechanism of action of interferons has not been explained in every detail these agents are promising therapeutic means in a number of diseases.

The charts of 35 women with primary malignant non-Hodgkin's lymphomas (NHL) of the breast were retrieved from the files of the Istituto Nazionale Tumori, Milan, over a 30-year period (1957 to 1986). These cases represented 0.1% of the more than 25,000 primary malignant tumors of the breast treated during the same period. The median age of these patients was 57 years (range, 28 to 81 years). In most cases, the clinical diagnosis was carcinoma. The tumors were either Stage IE(48%) or IIE(52%) at presentation, and only two patients had B symptoms. The right breast was involved in 17 patients, the left breast in 14, and both breasts in two. According to the updated Kiel classification and the Working Formulation (WF) for Clinical Usage, three cases were lymphoplasmacytoid (immunocytoma) NHL (WF, A); three, centroblastic-centrocytic, follicular NHL (WF, B); four, centroblastic-centrocytic, diffuse NHL (WF, F); 17 centroblastic NHL (WF, G); three immunoblastic NHL (WF, H); two B-lymphoblastic NHL (WF, I); and one, a Burkitt-like NHL (WF, J). Treatment consisted either of a combination of surgery, radiation therapy, and chemotherapy or radiation therapy and chemotherapy. The follow-up period for 32 patients ranged from 6 to 161 months (mean, 45 months); 17 patients died of their disease. The prognosis appeared to be related to the histologic type and stage of the disease. Median survival periods were 63, 52, 42, and 47 months for centroblastic-centrocytic follicular, centroblastic-centrocytic diffuse, centroblastic, and immunoblastic NHL, respectively. The overall 5-year survival rate was 43%; the 5-year survival rate and the probability of freedom from progression at 5 years were, respectively, 61% and 50% for Stage I and 27% and 26% for Stage II disease.

This report demonstrates a thymic cyst arising in association with cervical irradiation for laryngeal carcinoma; a process not previously described. Thymic cysts are rare anterior mediastinal masses which have many etiologies, though an increased incidence of thymic cysts in association with Hodgkin's disease has been reported. This association was thought to be related to either mediastinal irradiation or cystic changes within a thymic focus of Hodgkin's disease. This case supports the theory that at least some thymic cysts arise secondary to irradiation.

The aim of the study was to evaluate what family characteristics and what morphological, functional and immunological changes of the gastric mucosa precede the development of gastric malignancy in a follow-up of 11-14 years. The material consisted of 301 first-degree relatives of gastric carcinoma patients, 183 relatives of pernicious anaemia patients, and of 358 control relatives of probands computer matched from the general population by age and sex for the carcinoma probands. All subjects were endoscopically examined in 1973-1976 and followed up to the end of 1987. According to cancer registry data, 11 cases of malignant gastric tumours (9 carcinomas, one carcinoid tumour and one anaplastic tumour with suspicion of Hodgkin's disease) had been diagnosed during the follow-up: 6 belonged to gastric carcinoma, 2 to pernicious anaemia and 3 to control families. The occurrence of malignancy was significantly related to the presence of advanced gastritis with atrophy and of intestinal metaplasia before the start of the follow-up. In relatives with achlorhydria and low serum pepsinogen I levels the incidence of malignancy did not significantly differ from that in controls of similar age and sex distribution. The risk of getting malignancy was about four-fold in female members of gastric carcinoma and pernicious anaemia families but was not increased in control families. The risk was increased only in female members and concerned only gastric malignancy being the expected one or even lower than the expected in regard to malignancies of other location.

The case history is reported of a patient with a carcinoma of the duodenum 30 years after blunt abdominal trauma at the site of the 'scar' in the duodenum. Thirteen years after the trauma the patient was treated with chemotherapy and abdominal irradiation for a relapse of Hodgkin's disease. At follow-up, 25 months after the operation, he had no local recurrence of Hodgkin's disease or duodenal cancer. The possible relation between the cancer and the abdominal trauma, chemotherapy and abdominal irradiation is discussed.

The results of cryopreservation of sperm from cancer patients were retrospectively reviewed in an effort to better understand the relationship between semen quality and the presence of different kinds of cancer. The semen analysis results for 146 patients referred to our infertility center for sperm banking over a 2-year period were examined. These patients were divided into three groups according to their diagnosis: group I, prevasectomy controls; group II, patients with lymphoma and Hodgkin's disease; and group III, patients with testicular cancer, e.g., seminoma, embryonal cell carcinoma, or teratocarcinoma. The seminal parameters assessed included sperm count and prefreeze and postthaw motility and velocity. For these parameters, significant decrease from control values (P less than 0.05 to P less than 0.01) was seen in groups II and III. The specimens from group I patients retained good motility and velocity after thawing. Our results indicate that semen quality is adversely affected by the presence of cancer in the body.

Programmed cell death is a physiological, energy-consuming mechanism leading to suicide of the cell. Cell death is accomplished by the activation of endonucleases that fragment the cell's nuclear DNA. Some tumour cells remain susceptible to programmed death. These are hormone- and growth factor-dependent tumour cells. Hormone or growth factor deprivation induces signals leading to apoptosis. Other tumours gain strong resistance to apoptosis. One of the normal functions of the bcl-2 gene is to provide longevity to memory B cells. When this gene becomes translocated in follicular B cell lymphomas, it renders lymphoma cells resistant to apoptosis. Latent membrane protein encoded by an EBV gene, either by itself or by amplifying bcl-2, enables tumour cells (nasopharyngeal carcinoma; Reed-Sternberg cell of Hodgkin's disease) to resist apoptotic death. Loss of antioncogene p53 provides for resistance against programmed cell death. Breakdown of resistance to apoptosis in tumour cells can be achieved by oncolytic viruses; generation of lymphotoxin and tumour necrosis factor; monoclonal antibodies; transfection with plasmid vectors carrying p53; gamma irradiation; and certain chemotherapeutic agents.

In populations with non-HIV immunodeficiency, non-Hodgkin lymphoma and soft tissue sarcoma, especially Kaposi's sarcoma, are the most prominent tumours, but Hodgkin's disease, gastric carcinoma, squamous cell skin cancer, malignant melanoma, hepatoma, myeloid leukaemia and/or colorectal carcinoma have been linked in various studies. Population based cancer registries and cohort studies of HIV infected persons have generally failed to detect HIV related increases in total cancer incidence or in specific tumours other than non-Hodgkin lymphoma and Kaposi's sarcoma; however, associations with anal carcinoma, hepatoma and Hodgkin's disease have been suggested by some studies. Although not indicating increased risk, HIV induced immunosuppression has been linked to an acceleration of cervical and anal neoplasia and to increased aggressiveness of Hodgkin's disease with a relative excess of the mixed cellularity type. Advances in treatment for HIV infection will delay progression to AIDS and may allow an altered natural history to emerge, including the occurrence of excesses of additional cancer types.

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.

Anaplastic large-cell Ki-1 lymphoma is defined by its characteristic histological appearance, reactivity with antibodies against CD30, and possibly by a chromosome marker t(2;5)(p23;q35). Because of its pleomorphic appearance, sinus distribution, and frequent reactivity with EMA, this lymphoma is often mistaken for other diseases such as metastatic carcinoma and malignant histiocytosis. The clinical features of this lymphoma are unusual and include a young median age and frequent extranodal disease with skin being a common site. Although remission is easily achieved, relapse is common and combination chemotherapy is suggested. The role of Ki-1 antigen in normal lymphocyte function, the cell of origin of anaplastic large-cell Ki-1 lymphoma, and its relationship to Hodgkin's disease are important questions that hopefully will be answered in the near future.
