We studied the thyroid function of 64 patients with Hodgkin's disease who received mantle irradiation during the period 1966 to 1976. More than two thirds (44 of 64) had some thyroid dysfunction. Twenty had mild dysfunction manifested by an abnormal thyroid-stimulating hormone response to thyrotropin-releasing hormone. Twenty had what could be termed compensated hypothyroidism while four were overtly hypothyroid. The severity of dysfunction was not related to age, sex, or chemotherapy. We found, however, that decreased thyroid function was inversely proportional to the length of time between a diagnostic lymphangiogram and the radiation therapy. These results are consistent with the hypothesis that the iodine load of the lymphangiogram renders the thyroid gland more radiosensitive. Thyroxine suppression of the thyroid gland during the period from the lymphangiogram through the termination of radiation therapy is suggested as a means of avoiding thyroid injury.

Clinical and biochemical assessment of thyroid function was undertaken in patients with Hodgkin's disease at designated points following diagnosis. At diagnosis, two of 20 patients had either abnormally low routine thyroid indices, or elevated thyroid stimulating hormone (TSH) levels that were not due to iodine-based investigations. Following lymphography, 76.5% of patients had TSH levels that remained elevated for a median period of 3 months. No detectable thyroid dysfunction was induced during chemotherapy. Fifty-four patients were studied at a median time of 35 months after chemotherapy. One euthyroid patient had a nodular goitre, and one had abnormal thyroid indices. Tsh levels were elevated in 44% of patients, although the median TSH level for the group was normal. Half the patients had abnormal TRH stimulation tests. Sixty patients were studied after irradiation and chemotherapy. Four patients had clinical thyroid dysfunction, and 10% of routine thyroid indices were abnormal. TSH levels were abnormal in 80%, with a markedly elevated median level. All thyroid releasing hormone stimulation tests were abnormal.

Thirty-five patients, 38 to 88 years of age, were treated with 125-Iodine or 192-Iridium interstitial implants at Stanford University Medical Center between July 1974, and December, 1978. There were 25 primary epithelial malignancies, eight extensions from intrapelvic organs and two metastatic tumors (hypernephroma and Hodgkin's disease). The involved sites were: urethra (6 patients); vulva (9 patients); vagina (8 patients); anus (7 patients); cervix (5 patients). Implantation was usually performed to treat evident or microscopic disease in conjunction with external beam pelvic treatment with or without local excision. Computerized implant preplanning was used. 125-Iodine seeds were inserted either directly or within absorbable suture Polyglactin 910; 192-Iridium in nylon carriers was placed by suture or transperineal template. Two patients were lost to follow-up leaving 33 patients, 27 of whom are alive and free of local disease from 37 to 76 months. The overall local control rate was 88%, or 29/33 patients. All four local recurrences appeared before 24 months. Minor complications included: 10 patients with transient mucositis, four with superficial ulcers, and one patient with infection at the implanted site. Two major complications occurred: a necrotic rectal ulcer requiring a colostomy and a contracted, painful bladder necessitating a urinary diversion. We conclude that in selected cases interstitial irradiation provides good local control of perineal and gynecological malignancies with low morbidity in this elderly and quite often fragile group of patients.

The percentage of cells with S phase DNA content (S cells) was determined by flow cytometry in cell suspensions obtained from 27 patients with non-Hodgkin's lymphomas. DNA was measured in ethanol-fixed cells stained with propidium iodide after RNase treatment. Cells from 17 samples were also exposed to [3H]-thymidine and labeling indices were determined. An excellent linear correlation was observed between the percentage of S cells calculated by flow cytometry and the labeling index (r = 0.95). To determine the relationship between the percentage of S cells and the clinical behavior of the tumors, the survival of the 27 patients was analyzed. None of the patients was undergoing antineoplastic therapy at the time of the study. The patients were separated into 2 groups according to the percentage of S cells calculated by flow cytometry: those with less than 5% S cells and those with higher than 5% S cells. Clinical follow-up ranged from 5 to 20 months. While 7 of 12 patients with tumors containing more than 5% S cells have died of lymphoma (median survival, 9 months), there has been only one death from lymphoma among 15 patients with tumors containing less than 5% S cells. The difference in survival between these two groups is statistically significant (P = 0.01).

DNA content and light scatter were measured by flow cytometry (FCM) in 103 patients including 43 patients with non-Hodgkin's lymphoma (NHL), eight patients with Hodgkin's disease (HD), 17 patients with acute lymphoblastic leukemia (ALL), ten patients with acute nonlymphocytic leukemia (ANLL), and 25 patients with chronic lymphoid leukemias. Controls consisted of 42 nonneoplastic specimens obtained from lymph nodes, spleen, bone marrow, and peripheral blood. Each specimen was analyzed after staining with a hypotonic solution of propidium iodide using nuclei isolated from chicken erythrocytes as an internal standard. The DNA content and light scatter of the human populations was expressed as a ratio between the DNA content (or light scatter) of the human G0--G1 cells and that of the chicken erythrocytes nuclei. The mean DNA ratio for the 42 nonneoplastic samples was 2.58 +/- 0.045 (SD). In these samples the DNA coefficient of variation of the human G0--G1 peak ranged from 1.48--3.28% (mean, 2.33 +/- 0.54%). The FCM data in the NHL was compared to morphologic diagnoses made according to the "working formulation of NHL for clinical usage" recently proposed by a panel of international experts. Eight of 17 (47%) low grade NHL, one of two (50%) mycosis fungoides, ten of 14 (71%) intermediate grade NHL, nine of ten (90%) high grade NHL, nine of 17 (53%) ALL, three of ten (30%) ANLL, and seven of 25 (28%) chronic lymphoid leukemias had abnormal DNA ratios indicative of aneuploidy. In addition, several cases had normal DNA ratios but G0--G1 coefficients of variation outside of the normal range. All cases of HD had normal DNA values except one case with a small percentage of near tetraploid cells. The mean percentage of cells with S-phase DNA content for the low grade NHL (2.2 +/- 0.8%) was significantly lower than that of the intermediate grade NHL (12.1 +/- 4.9%; P less than 0.0001). The mean S-phase value for the intermediate grade NHL was significantly lower than that of the high grade NHL (22.6 +/- 11.1%; P less than 0.001). The three prognostic categories of NHL designated by the new formulation were clearly distinguishable by the FCM data. Light scatter was not particularly useful for distinguishing nonneoplastic from neoplastic populations. The mean light scatter coefficient of variation of the ALL (15.2%) was significantly lower than that of ANLL (20.5%), however (P less than 0.04).

The determination of DNA content and [3H]thymidine labeling index was carried out on malignant lymph nodes from 74 patients with non-Hodgkin's lymphoma. Analysis of cellular DNA content was performed using propidium iodide as DNA-specific fluorescence dye. The ploidy was expressed as the DNA ratio between the relative DNA content of the human lymphoid G0/1 cells to that of chicken red blood cells. Forty-five of the 74 non-Hodgkin's lymphomas (61%) were aneuploid populations and the majority of these (91%) showed a hyperdiploid DNA content. A higher frequency of aneuploidy (72%) was observed in tumors with unfavorable histology than in those with a favorable histology (55%). Moreover, among aneuploid lymphomas heterogeneous populations were observed in 24% of the cases. The evaluation of flow cytometric data using Fried's deconvolution procedure showed no statistically different frequency of G0/1, S and G2 + M cells between the two groups of tumors with favorable and unfavorable histology. on the contrary, a statistically different frequency of G0/1 and S cells was observed between the two groups of tumors with low and high labeling indices (P less than 0.01). A correlation was found between autoradiographic and flow cytometric determination of S phase cells (P less than 0.001).

Cellular DNA content, Coulter volume, and light scatter were measured in cell suspensions from 30 non-Hodgkin's lymphomas in order to assess flow analysis as a quantitative and reproducible means of evaluating these diseases. Nonneoplastic control populations included 31 samples obtained from lymph nodes, spleens, tonsils, and peripheral blood. Cellular DNA and light scatter were measured on ethanol-fixed cells by flow microfluorometry using nuclei isolated from chicken erythrocytes as an internal standard. For DNA analysis, the cells were stained with propidium iodide following RNase treatment. The cellular DNA content of the human populations was expressed as a ratio between the DNA content of the human G0-G1 cells and that of the chicken erythrocyte nuclei. The mean DNA ratio for the 31 nonneoplastic samples was 2.83 +/- 0.08 (S.D.) In these samples, the coefficient of variation of the human G0-G1 peak ranged from 2.27 to 3.63% (mean 3.09 +/- 0.32%). Fifteen of 30 non-Hodgkin's lymphomas, including 7 of 15 low-grade lymphomas and 8 of 15 high-grade lymphomas, had abnormal DNA content, the majority containing hyperdiploid G0-G1 populations. In six malignant lymphomas with normal DNA content, the coefficient of variation of the human G0-G1 peak, corrected for differences in instrument setting was greater than that seen in the nonneoplastic populations. A good correlation between the percentage of cells calculated to be in the S phase of the cell cycle and the expected clinical behavior of the tumors was observed. In those lymphomas in which the S-phase percentages could be calculated, 11 of 13 low-grade lymphomas had less than 5% of the cells in S phase, and 7 of 10 high-grade lymphomas had greater than 5% of the cells in S phase. Thirteen of 21 neoplastic cases in which Coulter volume determinations were performed could be distinguished from the nonneoplastic controls on the basis of their modal volume. Although some correlation was observed between light scatter of ethanol-fixed cells and Coulter volume measurements on unfixed cells, light scatter was found to be less discriminatory. Altogether, by all three flow parameters studied, 26 of 30 (87%) of the neoplastic cases could be distinguished from nonneoplastic controls.

The aim of this study was to analyse dynamic cell proliferation parameters in non-Hodgkin's lymphomas. Sixty-one patients with newly diagnosed or with recurrent disease were given iododeoxyuridine (IdUrd) intravenously near 4 h prior to tumour biopsy. After staining with an IdUrd reactive antibody and propidium iodide, S-phase fraction (SPF), labelling index (LI), S-phase duration time (Ts) and potential tumour doubling time (Tpot) were determined by flow cytometry. Thirty-eight samples, 15 low grade (LGM) and 23 high grade (HGM) malignant lymphomas, were possible to evaluate. Twenty-three cases were excluded due to aneuploidy, insufficient amount of material or technical problems. Tpot values varied between 0.8-32.9 days (mean 7.0 days). HGM lymphomas had shorter mean Tpot times than LGM lymphomas (4.8 versus 10.4 days, p = 0.05). For Ts the range was 4.2-20.1 h (mean 9.1 h), and a difference between the two histological groups was demonstrated with a longer mean Ts for HGM compared with LGM cases (10.0 versus 7.8 h, p = 0.04). Tpot showed a negative correlation with SPF (P = 0.003), and Ts demonstrated a positive correlation to SPF (p = 0.02). The clinical significance of the dynamic cell proliferation parameters studied remains to be clarified, but the interrelationships between Ts/SPF and Ts/morphologic subtype might be factors of interest for future prognostic studies in malignant lymphomas.

Clinical trials of the liposomal form of water-soluble x-ray contrast agent triombrast (90 mg of iodine in 1 ml) was carried out in 23 patients with Hodgkin's disease, 9 with liver cirrhosis, and 6 with malignant tumors of different localizations. Distinct images of the liver and spleen appeared 2-2.5 h after intravenous injection of the formulation. They could be observed during 4-6 h by plane radiography. Liposomal hepatolienography permits identification of the structural alteration sites 0.8-1.0 cm in size in these organs. Administration of higher doses of the formulation (more that 0.5 ml/kg) was associated with such side effects as fever and hyperthermia in 30% of patients parallel with the side effects common for iodine-containing x-ray contrast agents. These side effects could be eliminated by previous administration of prednisolone and pipolphen. These side effects were not observed after injection of lower doses of the formulation (less than 0.5 ml/kg) sufficient for an essential improvement of the image contrast during computer-aided tomography.
