TITLE: Inhibitory effects of Estracyt on R-3327 rat prostatic carcinoma.
PUBDATE: 19771101
Estracyt (estramustine phosphate) injected intraperitoneally, 100 mg, per Kg. three days a week for four weeks, retarded growth of the R-3327 tumor in intact rats and in orchiectomized rats given androgen. The growth inhibition was accomplished by reduction of tumor deoxyribonucleic acid concentration and of the activities of acid phosphatase, leucine aminopeptidase, and other hydrolases. Histologic examination revealed cellular necrosis particularly prominent in the orchiectomized, androgen-treated rats. Estracyt did not affect the uptake of 65-Zn in the tumors but markedly reduced the high uptake in the dorsolateral prostate. There was no accumulation of 3H or 14C in the tumors after intravenous administration of 3H, 14C-labeled Estracyt, but the isotope concentrations decreased much in the same way as they decreased in the dorsolateral prostate. The isotopes were retained in the ventral prostate, where their concentrations were approximately twenty times higher than those in the muscle four hours after injection. The results demonstrate the value of the R-3327 tumor in the evaluation of drugs of potential clinical use for the treatment of prostatic cancer. The results also show that Estracyt has an antitumor effect which is not dependent on the antigonadotropic action of the drug.

TITLE: The pathological basis for skeletal scintigraphy.
PUBDATE: 19750801
Skeletal scintigraphy, which has now been established as a useful and accurate method of detecting early skeletal metastases and assessing their response to treatment, has been investigated for its pathological basis. Histological examination of several hyndred necropsy specimens, from sixty-eight patients who died from malignant disease, showed a significant increase of osteoid and immature woven bone in the presence of metastatic cancer. Tumour-cell suspensions of the VX2 carcinoma were injected into the medullary cavity or on to the periosteal surface of the ilia or tibiae of New Zealand white rabbits. A combination of bone destruction and new bone formation, similar to the autopsy material, was seen. There were at least two mechanisms for the new bone production. Initially, intramembranous ossification was seen in the fibrous stroma surrounding the tumour. Once the cortex was involved and cortical bone destruction had occurred, large amounts of woven bone resembling fracture callus were laid down. The new bone had a markedly increased avidity for bone-seeking isotopes, indicating why skeletal scintigraphy was useful. A further twenty rabbits, in whose ilia the VX2 carcinoma was growing, were treated by local irradiation. When treatment was successful the tumour was destroyed, the production of new bone ceased, and the lesion lost its increased avidity for bone-seeking isotopes, indicating that skeletal scintigraphy could be used to assess the response of skeletal metastases to therapy.

PUBDATE: 19860201
Patchy necrosis of the skin is a rare and unpredictable complication of oral anticoagulant therapy. Of the four patients that we have seen with this disorder, three had metastatic adenocarcinoma; in two, this was an unexpected finding. The association of a malignant neoplasm with warfarin-induced skin necrosis has not been emphasized previously. Whether such necrosis represents a clue to the presence of cancer or occurs only coincidentally in patients requiring anticoagulant therapy because of adenocarcinoma-associated thrombophlebitis must await further experience. A congenital or acquired deficiency of protein C may be the primary initiating factor.

PUBDATE: 19881001
We studied cases of stage I endometrial adenocarcinoma encountered at our institution during the period 1970-80. Five out of 164 of these tumors showed a diffusely infiltrating pattern of growth. Two of the five patients died of cancer within 5 years, with a 5-year mortality of 40%. A control group of 15 patients seen over the same period showed a 5-year mortality of 13.3%. Thus, the diffusely infiltrating pattern of growth was indicative of poor prognosis in endometrial carcinoma in stage I disease.

PUBDATE: 19860201
We have evaluated 31 patients with advanced non-small cell lung cancer treated by short-term 5-day vinblastine infusion combined with bolus cisplatin. Nine of 31 patients (29%) had partial and complete responses. Although five of nine (55%) of the responders were alive at greater than or equal to 1 year, three of the 31 patients experienced drug-related mortality. Our experience, as well as a review of previously reported trials in the literature, suggests that the infusion schedule of vinblastine offers no advantage over the bolus schedule.

PUBDATE: 19810301
Postoperative contracture is a rare cause of the secondary obstructions of the vesical neck, besides remnants of prostatic adenomas, recurrent adenoma and prostatic cancer. It appears morphologically either as circumscribed sclerosis, as so-called sphincter sclerosis, or as extensive contracture of the entire prostatic urethra. Severe postoperative contracture with an iris-shaped membrane at the site of the internal sphincter is the most frequent form up to one year after primary surgery. The overall incidence has been given as 1.37%, of which 13.6% were refractory to therapy and recurred. Special forms of therapy are discussed.

TITLE: Strategy (motivation) for detection of early breast cancer.
PUBDATE: 19800801
For successful strategy to increase motivation for mass screening for detection of early breast cancer, three elements are needed: 1) women at risk must be taught the necessity of the examination; 2) they must be made aware of the existence of the facility, which must be made easily accessible; and 3) they must be reassured that the examination is simple, effective, and safe. Mass screening for breast cancer is the only proven method that has the potential to reduce the stationary death rate from the disease. Until true primary prevention is developed, it is necessary to make mass screening ever more efficient, economical, and safe. At the same time, increasing efforts must be made to motivate women to accept such mass screening.

PUBDATE: 19820601
Circulating immune complexes were determined in 48 patients with oral squamous cell cancer, 17 patients with oral keratosis and 49 controls, using a rapid sensitive assay using a Staphylococcus aureus immunoadsorbent. Concentrations of immune complexes were significantly higher in patients with oral cancer and in patients with oral keratosis than in controls, but the levels in those with oral cancer were not significantly different from those in keratosis. Immune complexes might be responsible for the cell-mediated immune defect in patients with cancer in the head and neck.

TITLE: The estimation of false negatives in medical screening.
PUBDATE: 19780301
In a medical screening program for early detection of disease, one or more screening modes are administered to an apparently healthy population. Knowledge of the true disease status for all screened individuals would allow estimation of the false negative and false positive rates for each mode of detection and for the program as a whole. This paper develops capture-recapture methods applicable to programs as a whole. This paper develops capture-recapture methods applicable to programs when follow-up of individuals negative on screening is not performed or is incomplete. The methods require at least two independent modes of detection. Data from a breast cancer screening program illustrate the procedure. The results of four screening examinations at approximately one-year intervals and the long-term follow-up of all screened individuals support the usefulness of these methods in the evaluation of a screening program.

TITLE: Concanavalin A receptors on the surfaces of human breast cancer cells in organ culture.
PUBDATE: 19770101
The binding of concanavalin A (Con A) at the free apical membranes of surface tumor cells in human breast cancer explants grown in organ culture was studied cytochemically with horseradish peroxidase (HRP) as a marker. On the cell membranes in aldehyde-fixed explants or explants exposed to Con A at 4 degrees C, a continuous label covered the entire free surface of the cell, which indicated the dispersed distribution of Con A binding sites. The binding of Con A at 20 degrees C resulted in discontinuous label of the cell surface, with gaps of unlabeleled membrane and partial endocytosis of the label. Incubation at 37 degrees C, following the binding of Con A and HRP at both temperatures, induced more extensive, incubation time-dependent discontinuities of the surface label that led to complete disappearance of the label from the surface and its eventual endocytosis. Con A was topically stablized on the surface only in those regions where two membranes or a different part of a folded membrane were in close contact. No differences were found in the binding, redistribution, and internalization of bound Con A among the various tumors studied.

TITLE: Radiation dosage to the breast in well-women screening surveys.
PUBDATE: 19751201
The D.H.S.S. is supporting research in several centres to determine the feasibility of establishing a nationwide Breast Cancer Screening Programme. This paper answers the questions "What is the radiation dose produced by mammography, and is it safe?". In the context of well-women screening surveys a maximum skin dose of 2 R has been recommended. The variation of dose across the breast surface is recorded and the reasons for this enumerated. The lowest mean dose recorded with industrial quality film was 4-9 R, so that such fine-grain film cannot be used for this purpose. Doses within the recommended safety limit are achieved by the use of vacuum-packed film-screen combinations. The new rare-earth phosphor screens produce the lowest dose (0-2 R). There was no significant gonad dose. It is concluded that mammographic examination of well-women can be performed at safe radiation levels.

PUBDATE: 19760501
This study reports the experience at the Ellis Fischel State Cancer Hospital with the use of scalene node biopsy for the pretreatment evaluation of patients with carcinoma of the cervix uter. The study was stimulated by a report from the National Cancer Institutes which stated that impalpable scalene nodes contained metastatic cancer in 13 per cent of a series of 84 cases. By a meticulous biopsy technique, we were unable to confirm this high incidence, In a series of 73 cases, no impalpable lymph nodes were found to contain metastatic cancer regardless of the clinical stage of the cancer. Consequently, we have terminated the use of scalene lymph node biopsies in the staging of cervical cancer for primary treatment. The study is still in progress to evaluate patients with recurrent cervical cancer who may possibly require pelvic exenteration. Also, the procedure will be continued in patients referred for further treatment in whom carcinoma was first diagnosed as an unsuspected finding in a hysterectomy specimen.

A retrospective study was carried out utilizing the Records Department of the Health Sciences Centre, St. Boniface General Hospital, and the Manitoba Cancer Treatment and Research Foundation. Seventeen cases of malignant lympho-epithelial lesion were found. The pathology of all cases was reviewed. There were 12 females and five males. Sixteen cases involved the parotid gland and one the submandibular gland. The ages ranged from 17-65 years with the peak incidence in the fourth decade of life. Fifteen of the patients were Eskimos, all residing in the Northwest Territories; two patients were Caucasian. Most patients were treated with a combined modality of surgery with postoperative radiation. The clinical features, pathology, treatment, and final outcome are reviewed.

TITLE: Cancer incidence trends in white women of the San Francisco Bay Area.
PUBDATE: 19791101
The 10% increase in the incidence of all cancer observed in the total white population of the San Francisco Bay Area during 1970-75 is mostly due to the 19% increase in cancer among white females. The latter is largely a result of increased incidence of cancer of the corpus uteri, breast, and lung, and of malignant melanoma. Cancer of these four sites constitutes 85% of the increase in white women. The rise in uterine corpus cancer is limited to women over 50 years of age. An incidence peak in 1974 of breast cancer was followed by a substantial decrease in 1975. The 50% rise in female lung cancer is an extension of the increase that began in 1965. The almost 70% increase in melanoma among women since 1975 accompanies a comparable increase in melanoma among males after a decade of stable incidence rates.

TITLE: Adjuvant chemotherapy.
PUBDATE: 19780301
In this brief presentation, an attempt was made to illustrate why it is not possible to carry over chemotherapeutic trial results from one animal cancer to another or one human cancer to another without corrections for differences in (a) staging, (b) dose response, and (c) tumor regrowth rates. Interrelation of quantitative information on these same three variables has provided useful guidance in the planning and interpretation of experimental therapeutic trials. For example, such integration analyses show that selection and overgrowth of specifically and permanently drug-resistant tumor cells is a major cause of chemotherapeutic failure in cancers that initia-ly respond. Surgery followed by optimum chemotherapy improves the "cure rate" of all metastatic solid animal cancers that have been studied to date. However, surgery followed by chemotherapy fails in those animals in which the residual tumor cell burden (after surgery) is too large for the chemotherapy now available.
