58 death certifications (40 males and 18 females) of residents of the Canton of Vaud (Switzerland) which reported AIDS as the cause of death in 1986-1989 were matched with the list of incident cancers available since 1974 from the Vaud Cancer Registry. Such linkage was successful for 20 individuals (age range 25-63, median 37), mostly males (18/20), homosexual or bisexual (11/18) and affected by Kaposi's sarcoma (14 males and 1 female). Other identified neoplasms included one Burkitt's lymphoma, one prostate adenocarcinoma and one multiple myeloma (whose histological picture included, however, lymphocytosis in addition to plasmocytosis). Three additional malignancies (one undifferentiated skin cancer, one carcinoma of the salivary glands and one in situ cervical carcinoma), and one myelodysplastic syndrome had also been diagnosed from 1 to 2 years before AIDS death. Cancer was mentioned on the death certificate, in addition to AIDS, in only 2 cases. Albeit of limited size, the present report confirms that a systematic integration of AIDS and cancer registration statistics provides additional information, of particular interest for histological classification, on the AIDS-cancer relationship.

This prospective study was designed to determine the efficacy of iodized talc pleurodesis in patients with pleural effusions. Thirty-four patients underwent this treatment (three bilaterally) between October 1, 1989, and March 31, 1991. All patients had to have complete or nearly complete lung reexpansion after tube thoracostomy with fluid drainage less than 100 ml in 24 hours. A slurry containing 5 gm of talc and 3 gm of thymol iodide was instilled into the pleural space through the chest tube. Chest tubes were removed after complete reexpansion and clearing of the effusions, usually in 3 to 5 days. The patients' ages ranged from 26 to 88 years (average 50 years). Eighteen patients had lung carcinoma, two had mesothelioma, and one each had carcinoma of the ovary, breast, or anorectum, multiple myeloma, schwannoma, or Hodgkin's lymphoma. Two patients had an unknown adenocarcinoma primary and five other patients had acquired immunodeficiency syndrome. One patient had congestive heart failure. Nineteen patients had left, 12 had right, and three had bilateral pleural effusions. The effusion was serosanguineous in 26 and serofibrinous in eight patients. Serial chest radiography showed complete response in all patients. The period of follow-up ranged from 1 to 21 (average 4.9) months, with no recurrences. Twenty-three patients have died during the follow-up period, and there was no sign that reaccumulated pleural effusion existed in any, despite clinical evidence of systemic tumor progression. These observations indicate that intrapleural instillation of a slurry of iodized talc is a safe, adequate, and effective treatment for control of neoplastic or benign pleural effusions.

The authors found metastases to the heart in 10.7% of 1029 autopsy cases in which a malignant neoplasm was diagnosed. The lung was the commonest primary site (36.4%) and adenocarcinoma was the most frequent cell type (36.4%) of neoplasms metastatic to heart. Nonepithelial tumors accounted for 22.7% of cardiac metastases. Epicardium was involved in 75.5% of metastatic lesions and a pericardial effusion was present with 33.7% of epicardial metastases. Although hemorrhagic effusions occurred in only 12 cases with metastases to heart, these represented 76.4% of all such effusions. Lymphomas associated with the acquired immune deficiency syndrome showed the most extensive cardiac involvement. Primary sites and cell types of cardiac metastases have evolved over time and have been modified by chemotherapy, increased survival of cancer patients, increasing incidence of lung carcinoma, and recently by the acquired immune deficiency syndrome epidemic.

The CD4 glycoprotein serves as a receptor for the human immunodeficiency virus HIV, the etiologic agent of acquired immunodeficiency syndrome (AIDS). We have examined the expression of CD4 molecules in a clone (HT29-D4) derived from a human colon adenocarcinoma cell line. HT29-D4 cells synthesized a 60 kDa polypeptide immunoprecipitated with two anti-CD4 monoclonal antibodies after metabolic or cell surface labeling. This 60 kDa polypeptide was also immunodetected using the same antibodies in human acute lymphoblastic leukemia cells CEM which are known to express CD4. HT29-D4 cells can be induced to differentiate into enterocyte-like cells by removing glucose from the culture medium. Under these conditions, HT29-D4 cells form a polarized epithelial monolayer in which tight junctions separate the plasma membrane in an apical and a basolateral domain. The localization of CD4 molecules in differentiated HT29-D4 cells was exclusively restricted to the basolateral membrane domain as demonstrated by radioimmunoassay and indirect immunofluorescence studies. Therefore the HT29-D4 clonal cell line represents a unique model for polarized HIV infection of colonic epithelial cells and may be useful to understand some of the gastrointestinal disorders occurring in AIDS patients.

Between December 1986 and December 1988, the Italian Cooperative Group on AIDS-Related Tumours documented 49 HIV-related tumours other than malignant lymphomas (ML) and Kaposi's sarcomas (KS), predominantly among HIV-infected intravenous drug abusers (IVDA). Of 12 germinal testicular tumours collected, six were seminomas, two of which were pure embryonal and the other four embryonal mixed. Cervical carcinoma was observed in nine IVDAs (intraepithelial in eight and advanced, with rapid progression, in one). Lung cancer associated with HIV infection was reported in eight patients, of whom four had an adenocarcinoma, two a small cell carcinoma, one an epidermoid carcinoma and one a mesothelioma. All patients with non-small-cell-lung cancer (SCLC) were at stage III, while those with SCLC and mesothelioma had limited disease. Five out of eight presented with limited disease at onset. The median age was low; lung cancer occurred predominantly in young adults, of whom all but one were smokers. Three patients could not be treated; four died while on treatment because of progression of the neoplasia and one died of an overdose. Acute lymphoblastic leukaemia (ALL) was diagnosed in five patients. The immunophenotype was always Burkitt-like (L3), and acute myeloblastic leukaemia (M2) was diagnosed in one. Of the central nervous system (CNS) tumours, two cases of glioblastoma and one of medulloblastoma were described. Two cases of young adults with multiple myeloma and two cases of colorectal carcinoma were also reported. One case of chronic lymphocytic leukaemia, one anorectal carcinoma, one oral carcinoma, one pancreatic carcinoma, one thymoma, one kidney carcinoma, one malignant melanoma and thyroid carcinoma were also found.(ABSTRACT TRUNCATED AT 250 WORDS)

Although open lung biopsy (OLB) is frequently employed for diagnosis of pulmonary lesions in patients with Hodgkin's disease, the actual efficacy of the procedure in establishing a diagnosis in these patients, and its effect on their treatment and clinical outcome, have not been evaluated. We reviewed the results of OLB in 41 patients with previously diagnosed Hodgkin's disease (17 with stage II disease, 10 with stage III, and 14 with stage IV) who had pulmonary opacification on chest roentgenogram. Nineteen (46%) diagnoses were specific and 22 nonspecific. The most common specific diagnosis was Hodgkin's disease (12 patients); the others were Pneumocystis carinii pneumonia (3), solitary fungal granuloma (2), cytomegalovirus pneumonia (1), and primary lung adenocarcinoma (1). Specific diagnoses were made in 11 (69%) of 16 patients with discrete nodules or masses but in only eight (32%) of the 25 patients with non-nodular radiographic opacification. Eleven (58%) of 19 patients who were asymptomatic or had had symptoms for longer than 4 wk had specific diagnoses, compared to one of six patients (17%) symptomatic for 1 wk or less. Survival of hospitalization correlated more with stage of Hodgkin's disease than with specific diagnosis. However, treatment was changed after biopsy in 22 (54%) of the patients. The results suggest that OLB can be helpful in the management of patients with Hodgkin's disease and pulmonary infiltrates, both in establishing a diagnosis and in assisting the patients' management. OLB appears to be more helpful in patients with Hodgkin's disease than in patients with acute nonlymphocytic leukemia or the acquired immunodeficiency syndrome and pulmonary infiltrates.

At the M.D. Anderson Cancer Center (Houston), Listeria monocytogenes was cultured from 14 patients between 1980 and 1987. The case records of 11 of these patients were reviewed. Underlying malignancies included acute leukemia (three), lymphoma (two), myeloma (one), adenocarcinoma of colon (two), carcinoma of breast (one), carcinoma of lung (one), and Kaposi's sarcoma associated with the acquired immune deficiency syndrome (one). Listeria monocytogenes was cultured from blood (eight patients), cerebrospinal fluid (CSF) (two patients), and from both blood and CSF in one patient. All patients were receiving immunosuppressive therapy including corticosteroids in seven. An absolute neutrophil count of less than 1000/mm3 was noted in five. Bacteremia was the predominant type of infection and ten patients responded to antimicrobial therapy.

The role of retroviruses as causal agents in animal and human neoplasms is reviewed. Based on previous studies done on retrovirus caused mouse mammary adenocarcinoma, it is suggested that a treatment regimen with 6-propylthiouracil, chloroquine phosphate and 5-fluorouracil (which resulted in 77% and 65% complete mouse tumor remission), may be effective in treating AIDS and other retrovirus-caused diseases.

Circulating immune complexes (CIC) are known to be present in cancer patients and are responsible for much of the cancer-associated immunosuppression. Removal or modulation of these "blocking factors" can reverse the immunosuppression. Protein A from Staphylococcus aureus has the unusual property of binding to CIC with high avidity. Use of protein A as an immunoadsorbent in extracorporeal immunotherapy affinity columns has resulted in antitumor and antiviral responses in animals. Our group developed a multicenter trial to assess toxicity and antitumor response with this biologic response modifier alone. Overall, 24% (21 of 87 patients) had objective tumor regressions including both partial responses (PR) and less than PR. No complete responses (CR) were observed. Responses were observed in acquired immune deficiency syndrome (AIDS)-related Kaposi's sarcoma (six of 17 PR; two of 17 less than PR; overall, 47%), breast adenocarcinoma (five of 22 PR; three of 22 less than PR; overall response, 36%), colon adenocarcinoma, (one PR, one less than PR; overall response, 11%), and non-oat cell lung carcinoma (two of seven less than PR). The procedure was well tolerated and could be performed on an outpatient basis. No adverse reaction was observed in 735 of 1,113 treatments (66%). The most common adverse effect was an "influenza-like" syndrome consisting of fever and chills. Pain was present in 12% of the patients. There were no study-related deaths. Serum IgG and CIC levels did not statistically change due to therapy in responding or nonresponding patients. Complement levels remained within the normal range. Liver and renal tests remained stable throughout the study. In summary, protein A immunoadsorption of plasma is well tolerated in the outpatient clinic, has demonstrated antitumor activity in resistant solid tumors, and functions as a biologic response modifier.

Colonic adenocarcinoma developed in an intravenous drug abuser with the acquired immune deficiency syndrome (AIDS) that was diagnosed by the presence of antibodies to the human immunodeficiency virus (HIV), generalized lymphadenopathy, and biopsy proven esophageal candidiasis. The colon cancer presented atypically at a young age with no known risk factors and with a bulky primary tumor and a local fistula. AIDS and AIDS risk factors have been associated with Kaposi's sarcoma, lymphomas, and anal and oropharyngeal carcinoma. This report suggests a possible association between colonic adenocarcinoma and AIDS.
