Serum lipid-bound sialic acid (LSA) was measured with a recently described procedure in 108 healthy subjects and in 138 patients with a variety of solid tumors and hematologic malignancies. At the time of serum sampling, 128 patients had active disease and 10 patients had no evidence of disease. LSA was elevated in 104 of 128 (81.2%) patients with active disease, while carcinoembryonic antigen, analyzed in 74, was elevated only in 21 (28.4%) (P less than 0.05). Sensitivity of the serum LSA test ranged from 66% for breast and gastrointestinal cancer to 92% for lung cancer. In patients with lung cancer, ovarian cancer or Hodgkin's disease, LSA was correlated with the extent of disease and it also proved to be useful in following the course of disease. Our preliminary data indicate that this test can be used as a monitor of tumor burden.

Radioimmunodetection (RaID) of tumors containing human chorionic gonadotropin (hCG; choriogonadotropin) was evaluated in 25 patients by injecting 131I-labeled goat antibody IgG against hCG and performing total-body photoscans with a gamma scintillation camera 24 and 48 hr later. All 10 testicular cancer patients with proven tumor sites had positive RaID results, whereas three cases without known tumor were negative. Four patients with hydatidiform mole and one with degenerative products of conception showed positive RaID results consistent with elevated serum hCG titers. Two putatively false-positive results were obtained in patients with lung or ovarian cancer, whereas a false-negative metastasis to the liver of a patient with lung cancer and an elevated serum hCG titer was observed. Of 14 tumor sites found by RaID in 10 testicular cancer patients, 4 were revealed by RaID prior to any other detection method used and provided a lead time to definitive diagnosis by other measures of a few days to greater than 1 yr. Although a number of patients had high serum hCG levels, even exceeding 3 microgram/ml, the xenogeneic antibody was capable of localizing in tumor. No adverse effects were noted in any of the patients studied. Thus, hCG RaID appears to be a safe and effective method of detecting and locating hCG-producing tumors and has been found to disclose occult testicular cancers.

The effect of intrathoracic administration of adriamycin with closed tube thoracostomy drainage was investigated on patients with various malignant pleural effusions (13 lung cancer and one each stomach, breast, ovarian cancer, respectively). The doses of adriamycin ranged from 50, 30, 20, to 10 mg given to four groups of 4 cases respectively. Comparative study on effective rates, survival period after the administration, side effects and histopathological changes in autopsied cases was performed. The results obtained were as follows: 1. With regard to effective rates and histopathological changes, no difference was observed in the four groups in term of dose escalation of Adriamycin. 2. 50% survival period was similar within the groups administered 20, 30 and 50 mg of Adriamycin. However, the group receiving 10 mg showed slightly shorter survival period. 3. Although serious side effects were not observed in any groups, minor toxicities were mostly encountered in the 50 mg group. 4. It was concluded that in the treatment of malignant pleural effusion, an appropriate dose of intrathoracic administration of adriamycin was about 20-30 mg.

Marrow transplantation is effective treatment for a number of haematological diseases in patients under the age of 50 who have an HLA-identical sibling donor. It is generally successful when used early in the treatment of aplastic anaemia. It is the only treatment that offers long-term disease-free survival for patients with acute leukaemia who have relapsed at least once, with 10-30 per cent apparent cures. Although still somewhat controversial, it appears also to be the treatment of choice for patients with acute non-lymphoblastic leukaemia in first chemotherapy induced remission and for those with chronic myelogenous leukaemia in the chronic phase since approximately 50-60 per cent of these patients are surviving after marrow transplantation in complete remission, apparently cured. Marrow grafting is the only effective treatment for many patients with inherited immunological-deficiency diseases and certain genetic storage diseases. It is being explored for the therapy of patients with lymphoma, Hodgkin's disease, multiple myeloma, small-cell lung cancer, testicular cancer, ovarian cancer and genetic disorders of haematopoiesis. Cures of congenital Fanconi anaemia, Blackfan-Diamond anaemia, osteopetrosis, and paroxysmal nocturnal haemoglobinuria have been achieved by marrow grafting. Genetic disorders associated with haemolytic anaemia and cyclic neutropenia have been cured by marrow grafting in animals. Target disorders for marrow transplantation in humans are thalassaemia major and sickle cell disease, and, indeed, a first successful transplant for treatment of thalassaemia major has recently been described (Thomas et al, 1982). Marrow transplantation has been limited by the fact that many patients do not have HLA-identical siblings and very few have monozygotic twins. The Seattle team has now explored the use of less well-matched family member donors in more than 80 patients with leukaemia. These donors share one HLA haplotype genetically with the patient and are phenotypically identical at two of the three major HLA loci on the other HLA haplotype (Clift et al, 1979). Overall, the post-transplant survival appears more a reflection of the type and stage of the leukaemia than of the marrow donor. Patients with leukaemia grafted in relapse have a projected survival of 20-30 per cent and those transplanted in remission of 50 per cent. The incidence and severity of GVHD may not be significantly different from that of patients given HLA-identical sibling marrow grafts.(ABSTRACT TRUNCATED AT 400 WORDS)

An updated review of the anticancer agents hexamethylmelamine (HMM) and its water-soluble analog pentamethylmelamine (PMM) is presented. Severe gastrointestinal and hematologic toxicity have limited the use of HMM drug combinations in ovarian cancer. Combinations involving HMM, cyclophosphamide, cisplatin, and doxorubicin in advanced ovarian cancer have resulted in only moderate response rates, with little to no change in median survival of previously treated patients. HMM now is being studied in previously untreated patients with advanced disease, in combination with these agents. In lung cancer, HMM continues to be a part of intensive and other regimens for the treatment of small-cell and non-small-cell carcinoma, although the value of the HMM is yet to be determined. Future trials have been recommended to determine whether HMM has a role in the treatment of endometrial and prostatic carcinomas. Five phase I studies of PMM have demonstrated severe, dose-limiting gastrointestinal and central nervous system toxicities. Thus, this agent may offer little advantage over HMM. Further phase I studies, with different PMM dosage schedules, are necessary before phase II studies can be recommended.

Vinzolidine (VZL), a semisynthetic vinblastine (VLB) derivative, was tested against a variety of solid tumors in the human tumor clonogenic assay (HTCA). The emphasis was on continuous drug exposure because of the schedule-dependency of the vincas and long half-life of VZL. Of tumor types with more than ten samples tested, the percentage of cases exhibiting inhibition (50% or less of control) of tumor colony forming units (TCFU) was as follows: melanoma (48%), lung cancer (48%), breast cancer (40%), renal cancer (33%), and ovarian cancer (24%). In tumor types tested less frequently, inhibition of TCFU after continuous or one hour drug exposure was observed in 2/7 colon cancers, 1/3 pancreatic cancers and 3/4 gastric cancers. Paired analysis of tumors tested to both VZL and VLB demonstrated no significant difference in overall activity of these two vinca alkaloids. VZL appears to be a promising drug for clinical trials, with in vitro activity in melanoma, lung and breast cancers. More interesting is the suggestion of activity in gastrointestinal tumors, especially colon cancer which is generally resistant to drugs in the HTCA and in vivo.

4'-Epi-doxorubicin (4'-epi-DX) is a new doxorubicin derivative that in phase II human studies has been demonstrated to be less toxic than doxorubicin. Sixty-four patients with advanced solid tumors were treated with the drug combination of 4'-epi-DX and cis-dichlorodiammineplatinum (CDDP) at the doses of 40-60 and 50 mg/m2, respectively, every 21-28 days. Out of 52 evaluable patients, complete remission (CR) was recorded in 5, partial remission (PR) in 12, minor remission (MR) in 7, no change (NC) in 16 and progression (P) in 12. The median duration of remission in patients who achieved a CR and PR was 9+ months. In particular, out of 19 patients with ovarian cancer, 2 CR (second look) and 7 PR have been documented. One CR and 3 PR also have been observed in 21 patients with lung carcinoma. Complete and partial responses also have been documented in breast cancer (1 CR/1), in bladder carcinoma (1 CR/2), in renal cancer (1 PR/5) and in testicular cancer (1 PR/1). Hematologic toxicity was generally mild to moderate (leukopenia less than or equal to 1500 cells/mm3 in 3% of the patients; thrombocytopenia less than or equal to 120,000 cells/mm3 in 2% of the patients). Vomiting was present in almost all patients while alopecia has been recorded in 63% of the patients. No case of cardiac toxicity had been observed up to now (median cumulative dose of 4'-epi-DX:240 mg/m2, range 40-650 mg/m2). The combination of 4'-epi-DX with CDDP appears to be an active and well-tolerated regimen in ovarian cancer and lung cancer.

Sixty-six patients with advanced solid tumors were treated with 4'-epi-doxorubicin at a dose of 90 mg/m2 by rapid IV injection every 21 days until the disease had progressed or to a maximum cumulative dose of 540 mg/m2. Myelosuppression, nausea and vomiting, and alopecia were the almost frequent side effects, but their incidence seemed lower than that after a comparable dosage of doxorubicin. After a cumulative dose of 540 mg/m2 a significant decrease of QRS complex deflection on the electrocardiogram was detected, but no case of congestive heart failure was observed. Partial remission and minor remission were achieved, respectively, in nine (15%) and five (9%) out of 59 evaluable patients for a median duration of 6 months. Partial remission occurred in anthracycline-sensitive tumors like breast cancer (4 of 13), lung cancer (1 of 17), head and neck cancer (1 of 8), gastric cancer (2 of 4), and ovarian cancer (1 of 1).

This cohort study examined cancer incidence in 13,650 Connecticut cosmetologists who had held licenses for 5 years or more and had begun hairdressing school prior to January 1, 1966. Cancer incidence rates for the general Connecticut population, 1935-78, were compared with those for 11,845 female and 1,805 male cosmetologists. The females had a standardized cancer incidence ratio (SIR) of 112 (P less than .01). A significant excess of lung cancer (SIR = 141) and excesses of brain (SIR = 168) and ovarian cancer (SIR = 134) of borderline significance were observed. No significant cancer risk was evident for female cosmetologists licensed since 1935, even for those with 35 years or more of follow-up, although the SIRs for brain cancer, lymphoma, and leukemia were elevated. Female cosmetologists who entered the profession between 1925 and 1934, however, experienced a significant overall cancer incidence (SIR = 129) and significant excesses of respiratory, breast, corpus uterine, and ovarian cancers. Those with 35 years or more from time of first license appeared to be at the highest risk. Among males the overall cancer incidence rate was close to that expected (SIR = 105). Smoking habits and reproductive factors that could not be taken into account may explain some of the excesses among females. Although no specific occupational agent could be identified, the excess numbers of leukemias in females and brain cancers among males and females merit continued surveillance.

A large sample of cancer patients was reviewed over a two-year period (1978-1979) in 31 general and community hospitals representing five Italian regions, differing in terms of health care organization. Two thousand four hundred and six patients had breast cancer, 1692 lung cancer, 303 non-Hodgkin's lymphomas, 277 ovarian cancer and 235 Hodgkin's lymphoma. Relevant information was collected from medical records through specific pre-standardized and tested forms. The paper discusses the results obtained with respect to (a) general descriptive data of the population; (b) completeness and reliability of recorded data (e.g. staging, histological classification, therapy); and (c) accuracy and completeness of the follow-up. Consistency of the information obtained on selected items with published series of patients suggests that this methodology is worth a wider testing as a simple, inexpensive tool for routinely monitoring the care of cancer patients and the impact on it of organizational and educational interventions.
