TITLE: Allogeneic inhibitory activity of regional lymph node cells in the mouse isografted with methylcholanthrene-induced tumor.
PUBDATE: 19750601
In mouse bearing progressive cancer a decrease was present in the allogeneic inhibitory activity of T-lymphocytes, which constitutes the core of immunological surveillance system in mammalians. For tests, methylcholanthrene-induced tumor (MC-tumor) was isografted subcutaneously on the back between scapulae of C3H mice, and the lymphocytes were prepared from the regional axillary lymph nodes removed from these mice at 1, 2, 3, or 4 weeks after grafting. These lymph nodes cells were cultured together with 40-fold numbers of allogeneic JTC-11 cells derived from Ehrlich cancer cells in a culture medium containing 2.0% (v/v) PHA for 24 or 48 hours. The proliferation rate of JTC-11 cells (increased numbers) at weekly interval was considered the allogeneic inhibitory activity of lymph node cells. As a result it was demonstrated that in the early stage after tumor transplantation, i.e., in the first or second week, regional lymph node cells showed a strong allogeneic inhibitory activity, as in the case with lymph-node cells from normal mice, but at progressive stage of cancer, i.e., the third or fourth week when tumors were larger, such activity was completely lost. It seems that mice with progressive cancer showed a decrease of allogeneic inhibitory activity, i.e., a disruption of homeostasis was present.

TITLE: [Adriamycin, cyclophosphamide, and 5-fluorouracil in the treatment of metastasizing breast cancer (author's transl)]
PUBDATE: 19760601
In a prospective study eleven patients with metastasizing breast cancer were treated with 5-fluorouracil, adriamycin, and cyclophosphamide )FAC). Complete remission occurred in three patients, with two of them still in remission four and thirteen months later. Partial remission (50% decrease in tumour size for more than four weeks) was achieved in five cases, with three of them still in remission. Time for remission induction was one to three months. The mean duration of complete remissions is not yet reached after thirteen months- that of partial remissions was 6.5 months. Two patients showed stable disease for four and more than eleven months, respectively. Only in one case progressive disease was noticed. Mean survival time from the start of therapy was 7.5 months for all patients. For complete and partial responders mean survival is not yet reached after eighteen months. With one exception therapy was given on an outpatient basis. Experimental and clinical data on therapeutic synergism of adriamycin, cyclophosphamide, and 5-fluorouracil show no advantage of the three-drug combination over the combination of adriamycin and cylophosphamide alone.

TITLE: Cell kinetics of gastric carcinoma and other gastric lesions in rats by N-methyl-N'-nitro-N-nitrosoguanidine with or without Tween 60.
PUBDATE: 19750401
Male Wistar rats were divided into three groups for studying the chronic effect of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), in continuous dose of 50 mg/L in drinking water, or 50 mg/L MNNG and 0.4% Tween 60 in drinking water. From the 2nd to 50th week after the administration of MNNG, every 3 or 5 rats were sacrificed and autopsied after the intraperitoneal injection of 1 muCi 3-H-thymidine/g body weight at 2- or 3-week intervals. The resected stomachs were studied morphologically and autoradiographically. Six cases of experimental gastric cancer were produced that fulfilled Stewart's criteria. Autoradiographically, there was no significant different in the flash labeling index in the normal antral mucosa, in the non-pathologic antral mucosa, and in the cancerous lesion, but generation time and DNA synthesizing time of the cancerous lesion were 2 or 3 times longer than those of the glandular stomach of normal rats reported by Galjaard. They were also longer than those of the non-pathologic antral mucosa of rats treated with MNNG. These experiments results were discussed, comparing with cell kinetics of the gastrointestinal tracts in man.

TITLE: A pathologist looks at spontaneous regression of cancer.
PUBDATE: 19761101
We are all subjected to varying amounts of mutating, potential cancer-inducing events, which are cumulative. In most instances, the accumulations are repaired or are lethal. If a viable clone survives, it must proliferate in order to become manifest and eventually to overpower the host's normal regulatory and defense mechanisms. The proliferation may be incited and sustained by cocarcinogens, hormone excess, chronic infections such as schistosomiasis, and in the case of lymphoid cells, by immune incompetence. On the other side are the protective reparing enzymes, which serve to cut out the damaged segments of DNA and repair them as fast as they can. The normal homeostatic mechanisms tend to keep cell proliferation and activity within the beneficial bounds of need. The controlling forces that cause cells to stop reproducing themselves and differentiate to perform a useful function also tend to slow or even stop the useless proliferation if all the cells can undergo maturation to a postmitotic state. There are also the protective mechanisms of immunity: Sensitized B lymphocytes tag the antigenic sites of tumor cells and activate the T-cell macrophages to destroy the tagged cells.

PUBDATE: 19750301
All seventy-five cases recorded as giant-cell tumor of bone in the Swedish Cancer Registry for the years 1958 through 1968 were analyzed. At reexamination, fifty-three cases constituted genuine giant-cell tumor of bone and twenty cases were so-called "giant-cell variants". The genuine giant-cell tumors showed a significantly higher incidence in the urban than in the rural population. The recurrence rate was 42 per cent. Patients under the age of twenty-five rarely had recurrences. A high recurrence rate was found among patients with tumors located in the distal end of the femur and the proximal end of the tibia. Tumors penetrating through the bone cortex were more aggressive than those located entirely within bone, regardless of tumor size and presence or absence of spontaneous fracture. A malignant course was found in 11.3 per cent of cases, predominantly in patients with tumors in the femur. Histopathological grading was of no prognostic value. Primary en bloc resection with or without prosthetic replacement is recommended in patients over the age of twenty-five.

TITLE: Rauwolfia derivatives and breast cancer in hypertensive women.
PUBDATE: 19760701
Three groups of women were selected from a sample of death certificates that had been coded by the Office of Population Censuses and Surveys for all conditions mentioned on them: (1) all women with reference to both breast cancer and hypertension; (2) all women with reference to hypertension and other cancers; (3) a group of women with reference to hypertension without cancer, selected to match the breast-cancer patients with respect to five features. When the women with breast cancer were compared with both the women with other cancers and the women without cancer, there was a positive association between breast cancer and the use of rauwolfia derivatives, although neither the differences in the frequency nor duration observed were statistically significant. The association appeared to be strongest for use near the time of diagnosis of the cancer. This agrees with nearly all other data and would be expected if rauwolfia derivatives promoted the development of breast cancer from previously initiated cells.

TITLE: Responses of cancer patients in the MEM test: not just a function of charge on basic proteins.
PUBDATE: 19760701
It has been reported that lymphocytes from cancer patients give positive responses to PPD, myelin basic protein, tumour basic protein, and certain histone fractions in the MEM test. The underlying mechanisms of the MEM test are poorly understood, but it is widely assumed that it detects immunological sensitization to specific antigenic determinants. The cross-reactivity experienced is interpreted as indicating shared antigenicity. Since all the stimulatory proteins are strongly basic we investigated an alternative explanation that responsiveness is a function of electrical charge by comparing the known stimulatory proteins in the MEM test with two others of similar basicity: lysozyme and cytochrome-C. We obtained highly significant stimulation with PPD, tryptophane peptide of myelin, and tumour basic protein using Mantoux + cancer patients, but found no response to other basic proteins. We failed to confirm the reported activity of histone F2a. Our results indicate that basicity alone is insufficient to elicit response, and strengthens the concept that the MEM test is measuring sensitization to the determinants shared by myelin and tumour basic protein.

TITLE: Biochemical estimation of the basic dye-binding capacity of RNA from rat hepatoma.
PUBDATE: 19750101
Areas of hyperplastic livers that acquire hyperbasophilic properties at advanced stages of carcinogenesis apparently represent the sites of neoplastic trasnformation, and hyperstaining of cytoplasmic RNA with basic dyes also characterizes the cancer cells. Estimations of the RNA content of cell fractions from normal rat liver and solid Novikoff hepatoma provided no evidence that the intense staining of cancer cells could be explained on the basis of an increase in cytoplasmic RNA content. The possibility that cytoplasmic fractions of Novikoff hepatoma show greater affinity for basic dyes than corresponding normal fractions has been examined by means of a test-tube toluidine blue-binding assay. The results revealed that the dye-binding capacity of total cytoplasmic fractions from tumors is 75% higher than normal after Carnoy fixation which retains mostly ribosomal RNA. Assays on fresh ribosomes indicated that tumor ribosomes bind 71% more toluidine blue per mg of RNA than the ribosomal preparation from normal liver. This study thus demonstrates a greater affinity of tumor RNA for basic dyes, and a comparison of biochemical and cytophotometric analyses suggests that an increase in basophilia by a factor OF ABOUT 2 WOULD BE DUE TO A qualitative alteration in robosomal RNA molecules and/or ribosome structure in cnacer cells.

PUBDATE: 19770501
The difficulties which arise when comparing the different therapeutic attitudes concerning the treatment in the curable stages of cancer of the uterine cervix have led us to the formation of dosimetric criteria to be employed in the analysis of the intracavity therapy. We have established points of reference which can be utilized irregardless of the intracavitary technique therapy. We have established points of reference which can be utilized irregardless of the intracavitary technique employed. Furthermore, we have analysed those patients who have received the same dose of external irradiation in an effort to establish as the only variable the intracavitary treatment. Forty patients, receiving 4,000 rads tumor dose in 4 weeks, were reviewed and demonstrated a correlation between the reference volume of the intracavitary treatment (as defined by the three dimensions W, H, T) and eventual complications (4 cases of Rectitis 1). We now feel that with the utilisation of these dosimetric criteria we will be able to: minimize the risk of complication without augmenting the indicence of local-regional failures; facilitate the objective comparison of the efficacity of the different intracavitary techniques presently employed at the major treatment centers.

PUBDATE: 19750101
The potential carcinogenic effect of oral contraceptive (OC) agents in the induction of cancer in sex hormone target organs and the possibility that OCs may be important in reducing the risk factors for these malignant lesions are reviewed. Despite many clinical investigations no direct link between OCs and breast carcinoma or fibroadenoma has been found. 1 study purported that carcinoma in situ of the uterine cervix was increased among OC users, however, pretherapy cytologic examinations were not done. There is evidence that synthetic progestogens depress mitosis in uterine cancer cells. The association of taking diethylstilbestrol during pregnancy and subsequent development of adenocarcinoma of the vagina in the daughters was found to be highly signigicant (p less than .00001). It is concluded that certain OCs play a role in the genesis of vaginal malignant disease.

TITLE: Hepatocellular carcinoma in the Rhodesian African.
PUBDATE: 19770701
We have carried out a prospective survey of 28 primary liver carcinomas over one year. Hepatocellular carcinoma is the commonest malignancy seen in Rhodesian blacks, which results in a high index of suspicion and accounts for the 96.4% positive diagnosis before death in this study. The age distribution was evenly spread through adult life with no definite peak incidence. Some were young and without evidence of chronic liver disease, but many had the stigmata of established hepatic disease. This contrasts with the common assertion that in areas of high incidence for primary liver cancer those affected are mainly young and lack signs of chronic liver disease. The commonest presenting symptoms were abdominal pain and swelling and weight loss. Hepatomegaly, often tender and nodular, was present in all but one. The incidence of alpha-feto protein, 46.5%, is low compared with other countries where primary liver cancer is common. Hepatitis B antigen was absent in all 28, suggesting that there is no association between the persistence of the antigen and hepatocellular carcinoma in Rhodesia. Liver function tests, although abnormal, were never diagnostic of primary liver cancer. We have confirmed the association of high alcohol consumption and cirrhosis with hepatocellular carcinoma.

The relationship between incidence of lung cancer and the volume of traffic as indicated by auto exhaust concentration was examined; the results, though suggestive, did not yield consistent evidence of the association between them. Traffic jams in Nagoya began 15 years ago, a period that may not be long enough to provide definitive data on the incidence of lung cancer. The high standardized mortality ratio (SMR) of lung cancer was observed in cities with a population of less than 1 million and guns (rural areas) along the coast, although those in the metropolitan areas with populations of more than 1 million were average. The SMR did not correlate with various socioeconomic conditions and industrial air pollution. Meteorologic or geologic conditions and ocean currents were not associated with SMR of lung cancer by city and gun. The population of a gun or of some cities was not large enough to be statistically significant, and the mortality rate of lung cancer was not always stable.

PUBDATE: 19771201
Due to the high frequency and usually late diagnosis of cancer of colon and rectum the "haemoccult test" has been recommended as an easy, quick, and unexpensive method for stool determination of occult blood that will allow us to suspect the existence of these tumors in their early asymptomatic stages. The test was performed in 1437 patients attending the gastroenterology clinic which had no clinical evidence of bleeding, of these, 1150 returned the samples. In 52 (4,6%) the test was positive for occult blood. The studies performed revelated that 4 were upper gastrointestinal ilions, one ileal diverticulum and 40 (3,47%) patients had colonic disease of the latter 19 were diverticular disease, 1 crohnis disease of rectum, 2 adenomatous and 2 villous polips, 1 Hodkgin disease and 7 carcinomas. There were 6 false positive results. The high frequency of positive "haemoccult test" in colonic disease, specially benign and malignant tumors, make this test and appropiate method of this time in the detection for colo-rectal carcinoma.

With increasing evidence that cancer patients respond immunologically to their cancers, it seemed interesting to investigate whether or not the course of the second cancer differed from that of the first. If we assume that, in analogy to mammary cancer in the mouse, the cells of human breast cancers carry shared antigens (although this is by no means certain), we could expect that sensitization of the patient induced by the first cancer would enhance his immune response to the second and that this might be reflected in an altered clinical course. We evaluated 82 patients with a second breast cancer and found no difference in the course of the second cancer as compared with the first.

TITLE: Recurrent postmenopausal bleeding.
PUBDATE: 19771201
Thirty-four patients with recurrent postmenopausal bleeding are reviewed. All had previously undergone dilatation and curettage after a first episode of postmenopausal bleeding, and no pathological cause had been found. When they presented with recurrence of bleeding, 32 of the 34 patients underwent total abdominal hysterectomy and bilateral salpingo-oöphorectomy and the excised organs were submitted for histological examination. In 2 patients clinical cervical carcinoma was found and they received radiotherapy. Hysterectomy was warranted in 5 patients with endometrial glandular hyperplasia and in 2 with uterine fibroids. Fibroids which distort the uterine cavity can result in an inadequate curettage. In 2 patients, failure to take adequate endocervical cytology smears resulted in a pre-operative diagnosis of endocervical carcinoma being missed. In recurrent postmenopausal bleeding, the taking of an adequate cervical smear and repear dilation and curettage are indicated as initial procedures. In obese patients, in whom palpable ovarian tumours may be overlooked, and in those with distortion of the endometrial cavity due to fibroids, total abdominal hysterectomy with bilateral salpingo-oöphorectomy is preferable, because underlying genital cancer can be missed in these cases.
