Eleven specimens of breast lesions obtained from 10 male patients were analyzed for estrogen receptor protein (ERP). Three patients (ages 49, 77, 82 years) had infiltrating duct carcinomas with no axillary
metastases
. ERP in each of these was positive. Eight specimens with gynecomastia, one of which was obtained from the 77-year-old patient with carcinoma in the same breast, were also analyzed. Of these ERP was positive in a 59-year-old man who had cirrhosis of the liver; two patients with borderline ERP had
hepatitis
and testicular seminoma, respectively. No relationship between histopathologic features of the lesions and ERP results was found and it is too early to relate these ERP studies to prognosis in these patients. Review of available literature, including our cases, reveals that six of eight male breast carcinomas were ERP-positive.

Vincristine-high-dose methotrexate-citrovorum factor (VCR-MTX-CF) was administered preoperatively at weekly intervals to eight patients, four with primary tumors and four with pulmonary
metastases
. These patients had not received prior VCR-MTX-CF treatment. A similar treatment program was administered to five patients with pulmonary
metastases
who had received prior VCR-MTX-CF. Among the eight patients who had not received prior VCR-MTX-CF, complete responses were obtained in three with primary tumors (this was followed by surgical excision) and two with pulmonary
metastases
. Partial responses occurred in two additional patients. Partial responses were also obtained in two patients who had received VCR-MTX-CF. Chemotherapy and surgery in one patient with an extremity lesion resulted in preservation of the limb and useful function. The major toxicity was anorexia and weight loss. Other side effects included stomatitis, myelosuppression,
hepatitis
and transient renal impairment. The weekly program was highly effective when compared to responses obtained with the tri-weekly schedule utilized in previous studies.

Hycanthone was given to 15 patients with
metastatic cancer
in order to determine the maximum tolerable dose. The drug was administered in 5-day courses at 3-week intervals. The starting dose was 30 mg/m2/day and the highest dose level reached was 90 mg/m2/day. The most common (13 patients) side effect was nausea and/or vomiting. The dose-limiting toxicity was toxic
hepatitis
manifested as elevation in serum transaminases in eight of 15 patients and an increase in serum bilirubin in three patients. Hepatotoxicity was dose-related and was observed in two of 25 courses given at the dose level of less than or equal to 70 mg/m2 compared to seven of nine courses given at the dose level of greater than or equal to 80 mg/m2. Because of an unacceptable incidence of hepatotoxicity at higher doses, 70 mg/m2/day x 5 appears to be a safe dose for phase II studies.

Guinea pigs with established intradermal tumors and microscopic lymph node
metastases
were treated by intralesional injection of graded doses of living BCG or BCG CW. The lowest dose of living BCG used produced a significant cure rate and no grossly evident toxicity. An intermediate and the highest dose of living BCG used cured some animals but others lost weight and a significant number died as a result of the treatment. Histologic examination of animals with significant weight loss showed fatty degeneration of the liver, granulomatous
hepatitis
and histiocytic infiltration of the spleen. None of the doses of BCG CW used was toxic and they were at least as effective as living BCG in intralesional treatment. In some experiments in which treatment was delayed it was found that the extent of disease required to render treatment ineffective was about the same for living BCG and for BCG CW.

Transmissible ileal hyperplasia (TIH) was experimentally induced in weanling hamsters, and the development of lesions was characterized. Ileal lesions developed in two phases: a hyperplastic phase which was detected by Day 10 and an inflammatory phase which began by Day 20. Hyperplasia began as focal lengthening of villi with expansion of crypt-type epithelium onto villus walls. Diffuse hyperplasia of distal ileum developed; dilated, tortuous crypts penetrated subjacent supporting tissues; but
metastases
were not seen. Inflammation began in association with focal or segmental necrosis of crypt epithelium, and crypt abscesses developed. Severe pyogranulomatous inflammation of the ileal wall, focal peritonitis, mesenteric lymphadenitis, and portal
hepatitis
were common in advanced lesions. Development of ileal lesions was closely correlated with accumulation of particulate antigen, detectable by immunofluorescence, in the cytoplasm of mucosal epithelial cells. Antigen was also detected in ileal granulomas, mesenteric lymph nodes, and liver. There was simultaneous development of serum antibody specific for intracytoplasmic antigen. These studies comfirm that mucosal hyperplasia is the primary lesion in TIH.

Therapeutical possibilities and side effects of intrafocal BCG-vaccination into
metastases
of malignant melanomas are discussed. Only in one of our three cases, this special method of unspecific immunstimulation induced a remarkable regression of tumor size. The second patient showed a partial remission and in the third there was no effect at all. Besides local irritation with ulceration we observed severe generalized side effects in all patients. A granulomatous
hepatitis
, which represents the most severe complication of this therapeutical method, occurred in one case. Its successful treatment with tuberculostatic agents favors the assumption of an infectious genesis.

CEA is a beta1-glycoprotein (mol. w. approx. 200 000) which in embryonic life is usually found as a cell membrane associated antigen in the gastrointestinal (GI) tract and pancreas. Furthermore, it is secreted into body fluids. In healthy adults a very low serum concentration may be found. The clinical significance of CEA lies in its increased formation in primary and secondary adenocarcinomas of colon and rectum and pancreatic carcinoma, where values of 20 ng/ml and more are observed. However, other gastrointestinal (e.g. oesophagus, stomach, gall-bladder) and extragastrointestinal tumors (e.g. lung, breast, urogenital, prostatic, ovarial carcinomas) as well as non-malignant diseases mainly of the GI tract (e.g.
hepatitis
, cirrhosis, pancreatitis, colitis, diverticulitis) may provoke less frequent and lower increases in the CEA level. Healthy smokers also tend to show a slight increase in CEA concentration. A certain relationship exists between the CEA level and the size and extent of the tumor so that a decrease following operation may account for complete tumor removal, whereas a persistent or recurring increase in the CEA level is highly suspicious of
metastases
and/or recurrent tumor. Difficulties in proving and purifying CEA are mainly caused by multiple cross-reactions of CEA with other substances, e.g. blood group substances (A, B, Lea, Leb) and normal or other antigens (NGP, NCA, CEX, CCEA 2, NCA 2, CCA-III, FSA, BCGP). The radioimmunoassay is the most suitable method to determine CEA levels in body fluids. The 3 procedures used differ in the precipitation of the specific immune complex by ammonium sulphate (AS), Z-gel (ZG) or a second antibody (SA). Depending on the method, the upper normal limit in serum or plasma corresponds to approximately 2.5 (AS, ZG) or 12.5 (SA) nanogramme/milliliter. CEA determination in the urine is of interest in patients suffering from bladder carcinoma.

Hepatic regional treatment represents an attempt to improve tumor response by increasing drug concentration with low systemic toxicities. Recently in vitro and clinical studies have shown that the cytotoxicity of 5-fluorodeoxyuridine (FUDR) and 5-fluorouracil (5FU) can be potentiated by high doses of leucovorin (LCV). Two pilot studies with intraarterial FUDR, 5FU, and LCV were initiated. Since 1982, 221 patients with colorectal liver metastases were treated by various forms of long-term monthly continuous regional treatment using implantable ports or pumps. FUDR (0.05 to 1.7 mg/kg/d) was administered alone or combined with 5-FU and leucovorin. In 61 patients curative liver resection was possible and was followed by adjuvant arterial treatment. Overall median survival time (MST) was 15 months and increased to 36 months after liver resection. This was influenced by the following important factors: treatment, number of
metastases
, extent of infiltration, tumor volume, and minimal intraoperatively diagnosed extrahepatic disease. The response rate varied from 69% to 23%. Time of development of extrahepatic progression was not delayed by additional systemic treatment. Local side effects significantly depended on the duration of arterial infusion. The rate of biliary sclerosis ranged from 19% to 0%. Occurrence of chemical
hepatitis
was between 7% and 38%. In contrast, after combined intraarterial treatment with LCV, systemic side effects, mainly stomatitis and diarrhea, were dose limiting. Despite the improvement of survival after regional treatment, further randomized trials are mandatory to compare regional with relevant systemic treatment.

Using a sandwich enzyme-linked immunoassay, plasma total cathepsin D concentration was assayed in 40 breast cancer patients and 84 patients with various liver diseases and compared to that of 52 normal subjects. There were no significant variations found in breast cancer patients related to tumor size, node invasiveness or
metastases
. In normal women, cathepsin D levels were slightly but not significantly increased in the luteal phase and in pregnancy. By contrast, plasma cathepsin D concentration was significantly increased in 70-75% of patients with liver disease (cirrhosis, hepatocarcinoma,
hepatitis
), but not in those with liver steatosis. Cathepsin D was independent of most of the plasma hepatic function tests and was correlated with alpha-fetoprotein in cirrhosis and with alpha-fucosidase in primary hepatocellular carcinoma. We conclude that plasma cathepsin D is not a useful marker in breast cancer. However, since the cellular level of this protease is associated with risk of metastasis in breast cancer, clinical follow-up will be required to test whether high cathepsin D plasma concentration has any prognostic value in liver cirrhosis and primary hepatocarcinoma.

To assess the feasibility and effectiveness of combined therapy on locally advanced cervical cancer, we entered 38 patients into a study. The patients were treated with mitomycin-C (10 mg/m2) on Days 1 and 30 and 5-FU (1000 mg/m2) on Days 1 to 4 and Days 30 to 33. In 5 weeks 4500-5000 cGy was given concurrently, followed by radioactive implants. Twenty-six patients had an early-stage disease (IB-IIB) and twelve had a late-stage disease (IIIB-IVA). Eighty-seven percent (33/38) of the patients had a tumor measuring 5 cm or more. The other 5 patients with a tumor size under 5 cm had biopsy-proven positive pelvic nodes; 2 of these 5 patients had a pretherapy hysterectomy. Tumor response, complete (CR) vs partial (PR), was assessed in 36 patients 3 months after completion of therapy. A CR was noted in 80% (29/36) of the patients. The PR status conferred a detrimental effect on the pelvic disease control (PDC), disease-free survival (DFS), and survival (S) while late stage correlated with the development of distant
metastases
(DM) and a poor DFS. PDC was obtained in 93% (27/29) of the patients who had a CR, as compared to only 43% (3/7) of those with a PR (P = 0.0228). The DFS and S rates were 59 and 77% for patients with a CR and 21 and 19% for those with a PR; respective P values were 0.0340 and 0.0002. Eleven percent (3/26) of the patients with an early stage developed DM, as compared to 50% (6/12) of those with late stage, (P = 0.0016). The DFS rates were 80 and 37% for patients with an early and late stage, respectively (P = 0.0141). Four patients developed transient neutropenia and one had transient thrombocytopenia. The second dose of mitomycin-C was omitted in 4 patients due to persistent neutropenia in 3 and to transfusion-related
hepatitis
in 1. Two percent (5/21) of the patients who had a staging laparotomy developed wound dehiscence. Three patients developed non-cancer-related small bowel obstruction requiring surgery. We concluded that this combined regimen was well tolerated. Although it was effective in controlling the cancer in the pelvis, this regimen failed to control DM in late-stage patients.
