Treatment of hormone-resistant metastatic carcinoma of the prostate with 5-FU, doxorubicin, and mitomycin (FAM'): a preliminary report.

We treated 19 patients who had hormone-resistant adenocarcinoma of the prostate (stage D-2) with 5-FU, doxorubicin, and mitomycin (FAM'). All patients had extremely poor prognostic factors. Of the 16 patients evaluable for response, 44% had stabilization of disease and 56% had progressive disease. The median survival time for the stable disease group was 48 weeks, whereas that for the nonresponders was 26 weeks. The difference in survival time was statistically significant (P less than 0.002). The FAM' regimen was well-tolerated with minimal nausea, no vomiting, and moderate hematologic toxicity.

A new method for treating carcinomatous biliary obstruction with intracatheter radium.

We describe a new method for relieving biliary obstruction due to malignant solid tumors. The method consists of placement of radium needles in a Ring biliary drainage catheter for three days. After removing the radium needles, the catheter is left in place to allow for repair of irradiated tissues, then it is removed. The object is to leave the patient with a patent biliary tree without a biliary drainage prosthesis. The clinical course of six patients treated by this method is described, and the autopsy findings in three cases are outlined. Three patients died with a serum total bilirubin ranging from 1--4.5 mg/100 ml, two to three months after removing the drainage catheter. Two patients died before the bile drainage catheter could be removed. One patient is alive with a bile drainage catheter in place. Possible modifications in technique and catheters are being considered.

Scintigraphic evaluation of lymphoma: a comparative study of 67Ga-citrate and 111In-Bleomycin.

Sequential whole-body scans with both 67Ga-citrate and 111In-bleomycin were performed for 14 patients undergoing staging for Hodgkin's disease or other lymphomas. A comparison or these scans gave a sensitivity in detecting the pathologically-proved tumor sites of 84% for 67Ga-citrate and only 56% for 111In-bleomycin. In 12 patients, the gallium scan demonstrated the lesions more clearly; in the others, the uptake of the two radionuclides was equal. In no case was a clinically diagnosed or histologically proved lesion identified by 111In-bleomycin that was not also demonstrated by 67Ga-citrate. 111In-bleomycin does not complement the 67Ga-citrate scan in the scintigraphic evaluation of lymphomas.

Prognostic classification of Hodgkin disease in pathologic stage III, based on anatomic considerations.

Fifty-two patients with pathologic stage III Hodgkin disease were studied in an effort to determine whether location of involved abdominal nodes influenced survival. Treatment consisted of total nodal radiotherapy with or without subsequent combination chemotherapy. Th initial radiation field was the "extended mantle," which included supradiaphragmatic nodes, the splenic hilar area, and paraaortic nodes to the level of L2-L4. Subsequently, lower paraaortic and iliac regions were treated ("lower inverted Y"). Patients with disease limited to the spleen and/or splenic, celiac, or portal nodes ("anatomic substage" III1) had a more favorable 5-yr survival than did patients with involvement of paraaortic, iliac, or mesenteric nodes ("anatomic substage" III2): 93% versus 57%, respectively (p less than 0.05). The addition of combination chemotherapy to total nodal irradiation was associated with improved survival of patients in stage III2, but not of those in stage III1.

Bone marrow involvement in non-Hodgkin's lymphoma: implications for staging and therapy.

We evaluated the incidence of bone marrow involvement in 121 patients with non-Hodgkin's lymphoma who were seen prior to the institution of definitive therapy. Involvement of the marrow was found to be dependent on both histologic type and the extent of extramedullary disease. It was observed most frequently in patients with poorly differentiated lymphocytic lymphoma (60%), but was not observed in 36 patients of all histologic types whose clinical evaluation and/or laparotomy revealed disease in stage I or II. Among 56 patients with poorly differentiated lymphocytic lymphoma in stage III or IV exclusive of marrow involvement, disease was observed in the marrow in 40 patients, or 71%. These observations, together with the results of previously reported therapeutic trials, suggest that staging laparotomy and total nodal radiotherapy alone may be of limited value in patients with poorly differentiated lymphocytic lymphoma when clinical evidence of stage III or IV disease is present.

Malignant histiocytosis: complete remission with combination chemotherapy.

A case of a 16-year-old girl with malignant histiocytosis involving the lymph nodes, bone marrow, peripheral blood, liver, and spleen is described. This patient achieved a complete remission with cyclic quadruple chemotherapy consisting of cyclophosphamide, vincristine, procarbazine, and prednisone (COPP). She is alive and free of disease more than 4 years after the completion of COPP and after having had maintenance treatment with a small dose of cyclophosphamide for 2 3/4 years. Such good results with the COPP regimen in malignant histiocytosis have not been reported previously, and it is suggested that this modality of treatment warrants further trial.

Results of involved field and extended field radiotherapy in patients with pathologic state I and II Hodgkin's disease.

A series of 44 previously untreated patients was found to have stage I or II Hodgkin's disease on the basis of a diagnostic workup which included laparotomy and splenectomy in 39 cases. The patients were randomized to either involved field or extended field radiotherapy. No difference was found in overall survival rates between the two groups. Regional recurrences were seen in four patients in the involved field group and in none of the extended field group. Regional recurrences were seen in four patients in the involved field group and in none of the extended field group. Radiotherapy to the extended field treatment port (generally an extended mantle) can be given with acceptable side effects. Staging laparotomy was of definite value, changing the classification and resulting therapy of two groups: (1) patients with clinical stage (CS) I or II, pathologic stage (PS) III involvement, who were treated with appropriately larger radiotherapy fields; and (2) patients with CS III, PS I or II, who were spared unnecessarily extensive radiotherapy.

Angio-immunoblastic lymphadenopathy. Diagnosis and clinical course.

The clinical and pathologic findings in 24 patients with "angio-immunoblastic lymphadenopathy with dysproteinemia" (AILD) are presented. The patients' ages ranged from 44 to 80 years, with a median age of 68 years. The disease has an acute onset. In many respects, the clinical presentation is suggestive of malignant lymphoma. Generalized lymphadenopathy was always present. Hepatomegaly was found in 20 patients, splenomegaly in 17, constitutional symptoms in 20 and skin rashes in nine. Twenty patients had anemia, with positive Coombs' test in eight of 14 tested. Polyclonal hypergammaglobulinemia was found in 17 of 22 patients. Two patterns of evolution were recognizable: (1) long survival (24 to 67 months) without treatment or after the administration of intensive combination chemotherapy; and (2) rapid progression (one to 19 months) regardless of the treatment given. Sixteen patients died; postmortem examination in 10 cases showed the cause of death to be attributable to severe infection in eight patients, to renal disease in one and to cardiovascular disease in one. No evidence of malignant lymphoma was seen in any of these autopsies. Histologically, the disease is systemic, with specific lesions in the lymph nodes. The spleen, liver, bone marrow, skin and lung are also involved, but the changes are less characteristic than in the lymph nodes. In the patients in whom sequential biopsies were performed, a trend toward restoration of the nodal architecture was observed. AILD is a clinical-pathologic entity in a spectrum of yet to be defined immune reactions. The clinical, laboratory and pathologic manifestations of AILD are consistent with an autoimmune disorder, in which a deficiency of the T-cell regulatory functions probably predisposes to an abnormal proliferative and autoaggressive reaction of the B-cell system. Surgical staging procedures do not appear to be indicated. Intensive cytotoxic treatment may be hazardous in some patients, precipitating their death, but long survival after such therapy has been observed in others. Supportive therapy and small doses of steroids appear to be a safer therapeutic approach.

Staging laparotomy in non-Hodgkin's lymphoma.

In 57 patients with non-Hodgkin's lymphoma, a clinical, radiographic, scintigraphic and pathological correlative study showed the following results: (1) the inferior venacavagram, lymphangiogram and gallium-67 scan have a low sensitivity in detecting lymphoma: their accuracy is high when the findings are interpreted as abnormal (93%, 83% and 80% respectively), but low when they are interpreted as normal (47%, 67% and 58% respectively); (2) the clinical evaluation of spleen and liver is unreliable; (3) the incidence of lymphocytic lymphoma in the para-aortic-iliac nodes is high; (4) a pattern of involvement by contiguity and a predilection for the spleen were observed in lymphocytic lymphoma; (5) in lymphocytic lymphoma there is no liver involve without concomitant splenic involvement; (6) no definite pattern of spread could be seen in histiocytic lymphoma; (7) surgical staging changed the classification of the lymphoma in 56% of cases, 46% being reclassified to a more advanced stage; (8) surgical staging significantly improves the assessment of the stage of disease and therefore permits accurate treatment planning.

Staging procedures in mycosis fungoides.

Mycosis fungoides (MF) in deep-seated lymph nodes, spleen or liver appears to be associated with a lack of response of the disease to topical external therapy. Fourteen patients with mycosis fungoides were clinically staged and had a staging laparotomy. Mycosis fungoides was found in the lymph nodes of 3 of these patients, in the spleen in 4 and in the liver in 2 cases. Patients with adenopathy, or with splenomegaly or abnormal spleen scans, should be considered for surgical staging to determine the extent of extracutaneous disease. The documentation of extracutaneous MF becomes necessary in the development of new therapeutic approaches.

Distinct alkaline phosphatase in serum of patients with lymphatic leukemia and infectious mononucleosis.

A distinct alkaline phosphatase (phosphatase N) was demonstrated in the serum of patients with acute lymphatic leukemia, chronic lymphatic leukemia, and infectious mononucleosis. This enzyme closely resembles that extracted from the thymus of mice with lymphoma or lymphatic leukemia, both in its electro-phoretic mobility and its substrate specificity. The phosphatase N activity was related to the clinical state of patients with lymphatic leukemia and disappeared with recovery from infectious mnononucleosis.

Extended mantle radiotherapy in Hodgkin's disease and malignant lymphoma.

The extended mantle field eliminates the necessity for splicing at the level of the diaphragm and thereby eliminates the potential for radiation-induced transverse myelitis. Our experience to date with 95 patients with H.D. or M.L. is described. Modifications in technique, including changes in the geometry of the field, shielding, time, dose, fractionation, and simulation are described. End results, an analysis of failures, and complications encountered are presented. Morbidity was acceptable despite the increase in integral dose, particularly in young patients who were not debilitated by disease. The danger of radiation-induced esophagitis, dehydration, hemoconcentration, and pulmonary embolism is stressed.
