A proportion of cancers in endocrine target tissues can show the presence of specific receptors for either steroid or polypetide hormones. Manipulation of the controlling hormones does not guarantee regression. A third of cancers in endocrine target organs (breast, uterine endometrium, and prostate) show a 50% reduction in size of lesions after hormonal therapy. If regression resulting from an aggressive form of therapy lasts a short while and the tumor reactivates by the time the unpleasant effects of the therapy wear off, the treatment is not palliative. Endocrine therapy in prostatic cancer is palliative but there is no evidence that is increases survival. 11 different progestational agents in
endometrial cancer
therapy in the past 25 years resulted in a 30-35% response. Response must be maintained by continual treatment and may last from 12 months to 7-8 years. In breast cancer, tumors with a significant level of estrogen receptor (ER+) have about a 60% chance of regression vs. tumors without estrogen receptors (ER-), 10%. Advanced cancers of the thyroid of the papillary or follicular type regress when the patient is treated by thyroxine, .3 mg daily. Leukemia and
lymphoma
are frequently treated, with varying degrees of success with corticosteroid therapy, which may also predispose the patient to intercurrent infection. Renal cancer has been often treated by medroxyprogesterone acetate or testosterone propionate, with little success.

During the past 3 years, eight hospitals and one cooperative study group have reported their initial clinical results with cis-dichlorodiammineplatinum (II). The most popular clinical schedule was 15-25 mg/m2/day for 5 days repeated every 3-4 weeks. Almost all patients had extremely advanced disease. Of 323 patients in whom response could be evaluated, there were 12 complete responses, 25 partial responses (greater than 50% decrease in tumor size), and 23 improvements (greater than 50% decrease in tumor size) for a 19% overall response rate. The tumor most sensitive to cis-dichlorodiammineplatinum (II) was testicular carcinoma in which seven complete responses, three partial responses, and three improvements were observed in 16 patients treated at Roswell Park Memorial Institute. Other sensitive tumors were
lymphoma
(63% response and improvements), squamous cell carcinoma of the head and neck (41% response and imporvements), and ovarian carcinoma (40% response and improvements). Complete responses were also seen in one patient with thyroid carcinoma and two with bladder carcinoma, while partial remissions were recorded in two patients with breast carcinoma and one patient each with acute myelogenous leukemia,
endometrial carcinoma
, renal carcinoma, malignant thymoma, neuroblastoma, adenocarcinoma of the lung, and an undifferentiated tumor of unknown origin. Five major types of toxicity were encountered: gastrointestinal, hematopoietic, immunosuppressive, otologic, and renal, with the last two generally the most serious. Serial audiometry testing can generally warn of the otologic toxicity and thus prevent permanent acoustic damage. Renal toxicity, which is similar to that seen with heavy-metal poisoning, appears to be dose related, cumulative, and only partly reversible, thus, severely limiting the repeated administration of cis-dichlorodiammineplatinum (II). Recent laboratory studies suggest that combination chemotherapy with this drug may be rewarding. Studies of this nature should be pursued along with attempts to find more effective less toxic platinum compounds.

The widespread availability and use of stapling devices have changed colorectal surgery. In 1980, Knight and Griffen developed the "double-staple" technique, using a circular stapler to transect a linear rectal staple line. This eliminated the need for a hand-sewn, distal purse string, which was sometimes difficult or even impossible to accurately place low in the pelvis. To evaluate this procedure, the authors have reviewed their results with the double-staple technique over the past 5 years. One hundred four patients underwent this procedure between 1985 and 1990 at Thomas Jefferson University Hospital (Philadelphia, PA). There were 60 men and 44 women, with a mean age of 62.4 years. Seventy-two patients underwent operation for carcinoma of the rectum or sigmoid. Thirty-five of these had preoperative radiation therapy. Other diagnoses included 1) diverticular disease, 2) rectal prolapse, 3) villous adenoma, 4)
endometrial carcinoma
, 5) fistula, 6) stricture, 7) Crohn's disease, 8) colonic endometriosis, 9)
lymphoma
, 10) ovarian carcinoma, and 11) ulcerative colitis. Incomplete "donuts" were observed in 5 patients. Diverting colostomies were performed in 23 patients, ileostomies in 3. Postoperative complications relating to the double-staple technique itself included a rectovaginal fistula in 1 patient. There were 3 clinical leaks (2.8%), all treated nonoperatively. No strictures were observed. As previously observed, the authors believe the double-staple technique offers certain advantages over traditional, hand-sewn and stapled anastomoses, for instance: 1) there is significantly less contamination, 2) the anastomosis is technically easier, and 3) bowel segments of different diameters can be easily anastomosed.

The determination of steroid hormone receptors obtained an increasing significance in the last years. It has contributed to the explanation of the mechanism of hormone regulation in the organism. The test allows an additional indication, exceeding the histological differentiation, both in breast and
endometrial cancer
with regard to prognosis of the patient and of success of an adjuvant or curative hormone therapy, especially in progredient cases. The receptor test can be decisive for the strategy of therapy. The test allows a better indication of the expected success of therapy for different types of leukemia and malignant
lymphoma
, too. But the success of a pure glucocorticoid therapy is often temporarily restricted because of the spontaneous occurrence of steroid resistant receptor mutants.

Cancer is a disease predominantly seen in the older age group. The most frequent forms are in males: lung, prostatic, stomach, colonic and bladder cancer. In females: breast, colonic, stomach cancer,
lymphoma
, leukaemia and rectal cancer. In view of the expected demographic figures a dramatic increase in the incidence of cancer is expected. The malignancies seen in the elderly respond generally poor to chemotherapy. Most cytotoxic drugs are excreted by the kidneys. Especially the renal clearance of anticancer drugs will therefore be compromised in the elderly, this should be considered when giving cytostatics. Mucositis, bone marrow toxicity, pulmonary and neurotoxicity are quite often enhanced in the older patient group. The indications for chemotherapy are limited. Chemotherapy should not be withheld from patients with advanced breast cancer and certain haematological malignancies. Further clinical research focussed on the elderly is warranted. Drugs with a mild spectrum of side effects deserve priority. Hormonal treatment is an important modality in breast, prostatic and
endometrial carcinoma
. The burden for the patients is limited and the advantages are well documented.

Twenty-four patients with pelvic disease were examined using a resistive magnet operating at a field strength of 0.15 T. and a R.F. frequency of 6.36 MHz. Spin-echo, multiecho (TR = 0.5-2 s; TE = 50-100 ms) and Inversion Recovery techniques (TR = 1.4 s; TI = 0.4 s) were employed. The proliferative processes of the pelvic organs were subdivided into: prostate (adenoma 5 cases, carcinoma 5); bladder (carcinoma 3,
lymphoma
1); uterus (fibroma 1, cervical carcinoma 6,
endometrial carcinoma
3). All patients were evaluated with conventional methods and had histological diagnosis. The little respiratory motion of pelvic organs allowed to obtain good coronal, sagittal and axial images. The main aspects of normal anatomy and pathology are analized and described. The tissue characterization of normal structures provides good anatomic details; multiplanar images depict the extent of the lesions properly. N.M.R. is an interesting method in evaluating the extension of pelvic masses and staging pelvic tumors.

HMFG antigen is a tumour associated glycoprotein that has been immunohistochemically shown to be expressed by malignant cells in breast and ovarian and to a lesser degree in gastro-intestinal carcinomas. We have developed a non-isotopic sandwich ELISA for secretory HMFG antigen utilizing a polyclonal catcher and a tracer monoclonal antibody (MAb). 52/52 of healthy medical students (controls) had a serum value under 400 U/ml whereas 15/30 patients (50%) with evident ovarian cancer and 13/37 (35%) with advanced breast cancer had a value exceeding 400 U/ml. From other patients with malignant tumours 2/14 (14%) with
endometrial carcinoma
, 0/5 with cervical carcinoma, 0/5 with vulvar carcinoma, 1/33 with gastro-intestinal carcinoma, 0/4 with oesophageal carcinoma and 2/45 of patients with leukemia or
lymphoma
had an elevated serum HMFG value. Four cases of Crohn disease, 3 cases of ulcerative colitis and 2 cases of pelvic inflammatory disease all showed a serum value below 400 U/ml. Progression of ovarian cancer was accompanied by increasing serum HMFG antigen levels. The antigen detected by our assay is different from CA 125 but may be related with the tumour associated antigen CA 15-3.

The fine needle aspiration (FNA) cytologic findings in 18 cases of metastatic neoplasms of the breast are reported. The cases were encountered in a combined series of 2,529 FNA breast biopsies, of which 666 were malignant; the metastatic neoplasms of the breast thus constituted 2.7% of all the malignant breast tumors. The series consists of 15 women and 3 men, with a mean age of 48 years (range of 11 to 73 years). Sixteen biopsies confirmed metastatic malignancy in patients with known extramammary primaries; the prebiopsy clinical diagnoses in six of the patients were benign breast lesions. In eight patients, the clinical differential diagnosis was either a benign or malignant primary breast lesion versus a metastatic malignancy. In two additional patients, the FNA biopsy identified metastatic neoplasms from unsuspected extramammary primaries. The metastatic neoplasms included three small-cell carcinomas of the lung, one squamous-cell carcinoma of the lung, two malignant melanomas, three ovarian malignancies, including a dysgerminoma, and one each of carcinoma of the fallopian tube,
endometrial carcinoma
, transitional-cell carcinoma of the urinary bladder, prostatic carcinoma, acute granulocytic leukemia,
lymphoma
, mycosis fungoides, hepatoma and neuroblastoma of the retroperitoneum. Recognition of unusual cytologic patterns raised the suspicion of, or confirmed the diagnosis of, malignancy in all cases, with no false-negative diagnoses. None of the cases were cytologically interpreted as a primary breast malignancy. Ancillary studies performed on the FNA material, including immunocytochemistry, contributed to a definitive diagnosis in three cases. FNA diagnosis of metastatic malignancy of the breast is essential in order to avoid unnecessary mastectomy and to ensure appropriate chemotherapy and/or irradiation treatment.

During a follow-up of 665 patients with carcinoma of the breast age 40 years or older, 46 developed a second primary carcinoma of the opposite breast and 30 developed a nonmammary malignancy (median FU = 6 yrs). Comparing our number of observed cases with the number of expected cases (calculated from the female age-specific incidence rate of the data of the Surveillance, Epidemiology and End Results (SEER) and from the actual cumulative person-years of follow-up), our patients with breast cancer did not have higher probability of developing additional nonmammary malignancy, but did have over five times the chance of developing a second breast cancer as other females to have any such cancer. Comparing the distribution of specific sites of our nonmammary second cancer with that reported by the SEER's study, the proportions of patients with colorectal, lung cancer, and
lymphoma
were similar. But we did see relatively more carcinomas of the uterine cervix, ovary, vulva, sarcoma, and stomach/duodenum, and fewer
carcinoma of the endometrium
. These differences could be explained by our small series, patient characteristics, and selected referral pattern.

The fluorescence of cells from 42 pleural and peritoneal effusions stained with Ca1 monoclonal antibody (Ca1MA) was studied by flow cytometry. In 14 of 17 malignant effusions a significantly higher intensity of fluorescence was observed in samples exposed to Ca1MA when compared with controls. There was no increase of fluorescence intensity in 25 benign effusions. The method failed in three malignant effusions: one due to
endometrial carcinoma
and two to malignant
lymphoma
. The sensitivity of the method was tested in experimental samples with a known percentage of malignant cells. The positive fluorescence with Ca1MA was detected in samples containing 0.1% of carcinoma cells. Flow cytometry with Ca1MA can be a relatively simple method of identification of malignant cells in effusions.
