Bone marrow transplantation (BMT) is now increasingly applied not only to hematologic disorders such as leukemias and aplastic anemia but also to some of solid tumors. We experienced ten cases of bone marrow harvest and six cases of autologous or allogeneic BMT during the period from June, 1986 to August, 1987. For autologous BMT cases, bone marrow cells were harvested and cryopreserved at -196 degrees C in liquid nitrogen tank and colony forming assays were examined to ascertain the colony forming ability of harvested bone marrow stem cells. Recovery of colony forming ability after cryopreservation in colony forming unit in culture and burst forming unit in erythrocyte is about 63 to 73% and well preserved. Among 6 cases undergone BMT, five cases are patients with advanced solid tumors including breast cancer, seminoma, lung cancer, malignant lymphoma and brain tumor and these 5 cases have undergone autologous BMT. Conditioning regimen for each cancer in autologous BMT differs based upon conventional chemotherapy regimen and two to four fold dose of conventionally used chemotherapy regimen were administered and after two or three days of high dose chemotherapy, cryopreserved bone marrow cells were thawed and infused. Peripheral white blood cells and platelets were recovered to more than 1000/microliters and 5 x 10(4)/microliters, respectively, within 21 days after bone marrow cell infusion. Disappearance or decrease in tumor size was observed in all cases except brain tumor even though those cases were advanced ones. After autologous BMT, recurrence occurred within three to five months in three cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Metastases are the most frequent malignant tumors of the kidney, but these lesions are of late onset in neoplastic disease. The 19 cases reported here were all investigated with various imaging techniques (CT 12 cases, ultrasonography 12 cases, urography 8 cases, angiography 2 cases, MRI 1 case). The most common primary malignancies were lung cancer, melanoma and cancer of the contralateral kidney. In this series, 8 of the lesions were solitary, and 9 were unilateral. Tumor vascularity was evaluated in 15 cases: 14 of these lesions were hypovascular. The differential diagnosis includes small cysts, lymphoma, bilateral renal cancer, multiple small abscesses and multiple small infarcts.

In evaluating patients for malignant disease, involved or uninvolved anterior diaphragmatic lymph nodes (ADLNs) may be observed at computed tomography (CT) evaluation of either the chest or abdomen. While ADLNs have been described on both chest radiography and CT, lymph nodes lateral to the cardiophrenic angles have not been as well illustrated. In this review, we examine the anatomy of the entire group of ADLNs and emphasize the importance of the more laterally placed ADLNs. ADLNs were identified at CT in 125 patients. Lymphoma (41%) was the malignancy most commonly associated with enlarged ADLNs followed by breast cancer (12%), colon cancer (10%) and lung cancer (6%). Twenty other malignancies accounted for 30% of the series. ADLNs lateral to the cardiophrenic angles were half as common as the other ADLNs. Right-sided nodes were more common than left-sided ones. Of 71 patients with two or more CT scans, 53 showed change in size of the nodes on follow-up examination. Our data do not support prior reports that suggest that a particular site of origin of malignancy exclusively involves one side or other of the ADLNs. In our experience, knowledge of the location and appearance of the entire group of ADLNs, including those nodes lateral to the cardiophrenic angles, has been useful in planning radiotherapy portals in Hodgkin disease, as well as staging and follow-up of other malignancies.

From 1975 to 1986, 15 cases (2%) of metastatic calcification associated with an underlying malignancy were found in a review of 702 autopsied cases with histories of malignancy. These underlying malignancies included 7 cases of lung cancer, 6 cases of malignant lymphoma, one case of breast cancer, and one of urinary bladder cancer. Squamous cell carcinoma was of the histological type most often associated with metastatic calcification in lung cancer, and ATL in malignant lymphoma. Hypercalcemia was found in 10 (83%) out of cases, and almost all were accompanied by renal dysfunction. Calcium deposits were most frequently observed in the kidneys and the lungs. It has been suggested that metastatic calcification in the lungs and kidneys of a patient with a history of malignancy showing hypercalcemia is sometimes accompanied by respiratory and renal dysfunction, causing the patient's condition to deteriorate.

From 1977 to 1982, 62 patients with various advanced malignant solid tumors were treated by HD-MTX-CFR therapy and totally 129 courses were given. Majority of the patients suffered from malignant lymphoma (10), osteogenic sarcoma (11), lung cancer (16), esophageal cancer (3), breast cancer (3) and malignant melanoma (4). All were confirmed by cytology or pathology except one primary liver cancer. There were clinically measurable lesions in 59 patients for evaluation of the treatment, and 3 osteogenic sarcoma patients without metastasis were given a postoperative adjuvant chemotherapy. 33 out of 62 had received chemotherapy and/or radiotherapy before. Dose of MTX ranged from 2 to 3 gm per course in most patients and dose of CF, from 9 to 12 mg every 6 hours for 3 days. 2 (3.4%) patients achieved complete remission (1 osteogenic sarcoma and 1 malignant lymphoma) and 8 (13.6%), partial remission (1 osteogenic sarcoma, 5 malignant lymphoma, 1 esophageal cancer and 1 breast cancer) with a total response rate of 15.9%. No response was observed in all 16 lung cancers. The main side effects of HD-MTX-CFR therapy were leukopenia, thrombocytopenia, elevation of SGPT, nausea, vomiting, mucositis, skin rash, fever and fatigue. All patients were followed more than 3 years. 4 patients are still alive (9, 9, 4 and 7 years, respectively), including 3 osteogenic sarcoma patients who received postoperative adjuvant chemotherapy and 1 mycosis fungoides.

Immune reconstitution after autologous bone marrow transplantation (ABMT) was studied in peripheral blood by phytohemagglutinin stimulated T-cell colony formation (CFU-TL) and by surface phenotype analysis of T-lymphocytes with monoclonal antibodies. Twenty-six patients (15 small-cell lung cancer, 5 lymphoma, 3 acute myeloid leukemia [AML], 2 germ cell cancer, and 1 melanoma) were conditioned with high-dose multiple drug combinations (plus total body irradiation in AML patients). No maintenance chemotherapy was given following treatment. Despite a rapid return to normal values of peripheral T3+, T11+ lymphocytes, the T4/T8 ratio remained below 1.0 up to 24 months after transplant, regardless of infection by cytomegalovirus (CMV). A high percentage (26% +/- 3%) of lymphocyte cells with immature phenotype (T8+, Ia+) was found during the first 6 months after transplant. Out of 84 cultures, performed in 26 patients, no growth was observed in 47 instances (22 patients) up to 28 months after grafting. Growth occurred in 37 cultures (11 patients, from 1 to 51 months after transplant) although it never reached the colony numbers of normal controls. Recombinant human interleukin-2 (rIL-2) added to lymphocyte culture induced proliferation in 8 (4 CMV-positive and 4 CMV-negative patients) out of 12 instances of no growth. In cases of depressed CFU-TL (20 cultures), rIL-2 induced a 48% and 92% increase in six CMV-positive patients and nine CMV-negative patients, respectively. These observations show that after ABMT and regardless of CMV status, defects in CFU-TL can be partially corrected by rIL-2.

The work environment in agriculture is complex, with many potentially hazardous exposures, but the overall mortality from cancer and other causes is rather low among farmers. However, several studies have consistently indicated an excess of certain cancer forms. Lymphomas, leukemias, multiple myeloma and also malignancies of connective tissue attract special interest, as being possibly associated with the use of pesticides. Phenoxy acid herbicides may play an etiological role, especially for non-Hodgkin's lymphoma, whereas the findings are more ambiguous for Hodgkin's disease and soft-tissue sarcoma, perhaps indicating an interaction with co-factors. The issue has been controversial for many years, however, and one of its aspects involves the use of phenoxy acids in the Vietnam war. Furthermore, DDT has been associated with lung cancer in mixed exposure situations, and with chronic lymphatic leukemia. Arsenical pesticides may have caused skin cancer in vine-growers. Further studies, especially of specific user groups and producers, may avoid the complex exposure situation in agriculture.

Following the intravenous injection of 75 MBq 201Tl-chloride we have assessed the uptake kinetics in the myocardium and in the primary tumour in 56 patients with lung cancer, 26 with breast cancer and 13 with mediastinal lymphoma. The time of maximal tumour uptake ranged from 8-20 min post-injection and did not differ significantly between lung cancer (mean +/- SD = 11.9 +/- 3.34 min), breast cancer (11.21 +/- 1.88 min) and lymphoma (11.76 +/- 3.25 min). The time of maximum cardiac uptake of 201Tl was 11.61 +/- 3.25 min. There was no significant washout of 201Tl from the tumours in the first hour after injection in the various malignant lesions studied. The time of maximal tumour to background activity was 18.3 +/- 0.59 min for lung cancer, 13.0 +/- 1.16 min for breast cancer and 16.7 +/- 1.04 min for lymphoma. The time course of 201Tl uptake in the tumours suggests that the mechanism of uptake is similar to that in the myocardium. The optimal time of 201Tl tumour imaging is from 20-60 min following injection and did not differ in various tumours studied.

On the basis of information obtained from a population-based cancer registry in Sweden, male patients with breast cancer (n = 95) were found to have experienced significantly more brain concussions and skull fractures than male patients with lung cancer (n = 383) or malignant lymphoma (n = 69). Other risk factors significantly associated with breast cancer among men were drug treatment associated with prolactin elevations, radiation treatment, family history of breast cancer among first-degree relatives, a history of gynecomastia, gonadal injury, and treatment for inguinal hernias. The results confirm some previously described risk factors for male breast cancer and suggest that events elevating plasma prolactin (e.g., drugs, brain concussions, and skull fractures) and events predisposing for inguinal hernias may be new risk factors for the disease. Using hospital charts is likely to underestimate exposure for different risk factors; therefore, the results need to be confirmed in studies that directly retrieve information. However, such studies are difficult or impossible to undertake in most countries because the disease is so rare.

Kinetics of blood-nitrosomethylurea (NMU) was studied in 68 patients with lung cancer, malignant melanoma and lymphoma who had received NMU-based combination chemotherapy. The results were used for computing main pharmacokinetic parameters such as logarithm of calculated initial concentration, time of half-elimination from blood, area under the kinetic curve of concentration, volume of distribution in the body and clearance. All those values were shown to significantly differ with individual patients. A longer retention of the drug in blood flow (as evidenced by increased time of half-elimination and area under kinetic curve matched by decreased volume of distribution and clearance) was registered in responders than in non-responders, the difference sometimes reaching statistical significance.
