Abstract
Twenty-five assessable patients with metastatic melanoma have been entered in a multicenter phase II study of two induction cycles of human recombinant interleukin-2(IL2), 18 x 10(6) IU/m2/d continuous intravenous (IV) infusion on days 1 to 5 and days 12 to 17. Dacarbazine (DTIC), 850 mg/m2 IV bolus was given on day 26. The cycle was repeated at 5 weeks. Maintenance therapy was scheduled 3 weeks after the completion of induction treatment, consisting of IL2, 18 x 10(6) IU/m2/d for 5 days alternating with DTIC, 850 mg/m2 IV every 3 weeks, for a total of 18 weeks. Six patients responded (24%); two complete and four partial. Stable disease was seen in five patients. None of the six patients with more than two sites of metastases responded. Maximum response was observed in the first 3 months of treatment. Progression-free periods of 6 months and longer were seen in the two complete responders (8 and 17+ months), in two of the four partial responders (7 and 12+ months), and in three of the five patients with stable disease (9+, 15, and 17+ months). Toxicity included fever, skin rash, fatigue, anorexia, and diarrhea in most patients. Two patients had a weight gain of more than 10%. Eight patients needed intensive care for the observation and treatment of a myocardial injury (one patient), ventricular tachycardia (one), hypotension and oliguria (four), and sepsis (two). Sequential treatment with IL2 and DTIC appears to be effective but not clearly better than could be expected of IL2 alone.

Abstract
Selective aspects of quality of life during supportive pamidronate (APD) treatment were assessed in breast cancer patients with osteolytic metastases. 144 patients were randomised to a pamidronate group (n = 76) or a control group (n = 68). A questionnaire measuring mobility impairment, bone pain, fatigue and gastrointestinal toxicity was administered at 3-monthly intervals. The analysis focused on changes in these quality of life domains over time. The median follow-up for both groups was 18 months. Mobility impairment and bone pain were significantly less in the pamidronate group as compared with the control group, due primarily to a rapid improvement shortly after initiation of pamidronate treatment. Thereafter, a gradual increase in these symptoms was noted in both groups. Gastrointestinal complaints and fatigue levels were similar over time in the two groups, suggesting that these symptoms are more dependent on disease-related events and cytotoxic treatment than on pamidronate treatment. The results indicate that reduced skeletal morbidity in breast cancer patients during pamidronate treatments is associated with an improvement in selective aspects of quality of life.

Abstract
The toxicity and therapeutic efficacy of the combination of recombinant interferon gamma (rIFN-gamma) and alpha (rIFN-alpha) was investigated in 15 patients with metastatic melanoma. Patients were treated with an escalating dose of rIFN-gamma and a fixed dose of rIFN-alpha administered s.c. 3 times a week. The maximum dose was well tolerated. The median survival time of the patients was 7 months; no clinical remissions were observed. In the majority of cases, expression of HLA class-I and -II antigens on the patients' peripheral blood lymphocytes and monocytes increased markedly during treatment. An increase in HLA-DR expression of peripheral blood T lymphocytes was correlated with a longer survival time. This suggests that activation of T lymphocytes may have a favourable influence on the course of metastatic disease. The in vitro anti-proliferative activity of IFNs on melanoma cell lines isolated from melanoma metastases during treatment of 3 patients was determined. In contrast to the lack of in vivo anti-tumour effect in patients, both rIFN-gamma and rIFN-alpha inhibited DNA synthesis of these melanoma cell lines in vitro, combined IFNs acting synergistically. Anti-proliferative activity observed in vitro occurred at IFN concentrations below the peak serum levels achieved in vivo.

Abstract
Eighteen patients with locoregional recurrence after primary surgery for carcinoma of the cervix and treated by radiotherapy were analyzed. An overall complete response of 88%, 16 of 18, was achieved. Five of sixteen patients (31%) developed a second locoregional recurrence. Response to radiotherapy seemed to correlate strongly with tumor volume. The overall 5-year survival for all 18 patients was 44%, and the disease-free survival, 39%. Only 22%, 4 of 18, had distant metastases in the subsequent course of the disease.

Abstract
Future scenarios on cancer in The Netherlands were made with the help of existing trends, demographic changes and expected developments in cancer research, prevention, screening and treatment. Until the year 2000, cancer incidence will probably increase by 1.5% per year, by nearly 3% per year and the need for health care facilities accordingly. Upon the request of Parliament, the Dutch government used this information to formulate a long-term cancer control policy. Faced with a restricted budget and a growing demand for care, the government plans to increase its efforts in the areas of prevention and screening and to improve the efficiency of cancer care. More attention will be paid to the quality of life of those patients who cannot be cured. Support for cancer research will be maintained at its present level.

Abstract
The effect of long-term bisphosphonate (APD) treatment on the morbidity from bone metastases in breast cancer patients was studied in a controlled clinical trial. 131 patients were randomized between treatment with APD (300 mg/day orally) or control. Systemic treatment for breast cancer was left to the discretion of the physician. The distribution of cases according to age, receptor status and previous treatment was similar in both groups. Patients were examined at 3-month intervals, while bone scans and radiography of relevant lesions in the skeleton were performed every 6 months. After a median follow-up of 13 months, the morbidity in the treated group was significantly less than in the controls. This concerned the occurrence of hypercalcemia, bone pain and fractures, and the need for radiotherapy of osteolytic lesions. In this interim analysis, APD treatment more than halved the requirement for specific treatment of bone lesions. The treatment is simple and well tolerated at a relatively low dosage. A higher oral dose was precluded due to gastrointestinal toxicity. Because the effect of APD on skeletal morbidity was not complete, efforts should be made to develop more effective and less toxic bisphosphonates.

Abstract
Samples of 37 fresh human ovarian tumor biopsies were screened to detect proto-oncogene amplification and ras mutations. Three samples showed c-K-ras2 amplification; none of the other oncogenes tested revealed any gene amplification. 5-, 25-, and 120-fold amplifications were assessed by dilution experiments and soft laser densitometry. Corresponding elevated levels of c-K-ras2 mRNA and p21 ras protein were found in the three tumors. Analysis by the polymerase chain reaction method to detect point mutations of codon 12 or codon 61 of Harvey-, Kirsten-, or N-ras showed only the wildtype sequence in all specimens. No correlation was found between ras activation and degree of tumor progression or histological subtype. DNA from one of the tumors with c-K-ras2 amplification proved to have high transforming activity in the NIH 3T3 tumorigenicity assay, but the transforming gene was not c-K-ras2.

Abstract
131 patients with osteolytic metastases from breast cancer were randomised to receive long-term oral treatment with aminohydroxy-propylidene-bisphosphonate (APD), 300 mg daily (n = 70), or to act as controls (n = 61) in a multicentre trial. Specific antitumour therapy was at the discretion of the clinician and variable. An interim analysis was made after a median follow-up of 13 months in the APD group and 14 months in the controls. There was a significant reduction in pathological fractures and severe bone pain in the APD group, and hypercalcaemia was prevented. Consequently the necessity for radiotherapy for skeletal complications was more than halved; the number of systemic therapy changes was also reduced. Gastrointestinal side-effects of APD led to a drop-out of 8% of patients. Oral supportive APD therapy is simple and convenient, and significantly reduced skeletal morbidity in advanced breast cancer.

Abstract
In this review different aspects of osteolytic bone metastasis of breast carcinoma including morbidity, pathogenesis, accompanying hypercalcaemia and treatment, are discussed. Bone metastases occur in many patients with breast cancer (percentages of up to 85% have been reported); although patients seldom die of bone metastases morbidity is pronounced. Literature data point out that humoral factors, such as prostaglandins and the recently described growth factors are of importance beside cell interactions between monocytes, lymphocytes, osteoclasts and tumour cells. Nowadays, no significance is attributed to parathyroid hormone (PTH) overproduction in this respect. The differential diagnosis between primary hyperparathyroidism and tumour-induced hypercalcaemia is not always easy biochemically; combinations of both do occur less frequently than has been assumed in the past. A new and promising line of investigations involves the growth factors, which can increase osteolytic bone resorption and may bind to epidermal growth factor (EGF) or PTH receptors, thus inducing some of the biological effects of PTH (including hypercalcaemia). Until recently it was exceedingly difficult to treat tumour-induced hypercalcaemia (TIH) (the acute condition). Since the availability of the bisphosphonates dichloromethylidene bisphosphonate (Cl2MDP) and 3-amino-1-hydroxypropylidene-1, l-bisphosphonate (APD) this treatment has become very simple. Preliminary results, derived from the literature, point out that bisphosphonate treatment might also be effective in providing long-term control.

Abstract
The chemotherapy of advanced ovarian cancer is reviewed. Treatment with single agents results in low remission rates and few complete remissions. The results have been improved with modern combination chemotherapy, which includes cisplatin, although a longer follow up is needed for definite conclusions to be made concerning survival. Toxicity and drug resistance remain important problems. The future prospects of treatment with emphasis on intraperitoneal chemotherapy are discussed.

Abstract
This review describes the state of the art for scintigraphic tumour detection using radiolabelled very pure (monoclonal) antibodies. In vivo imaging by scintigraphy may be useful for visualisation of cancer sites and treatment monitoring in oncologic patients. Imaging includes the computer-assisted processing of the scintigrams to remove background and non-target radioactivity. The clinical use of this method ("radioimmunoscintigraphy") depends, however, on the availability of the desired antibodies. Developments in the field of antibody labelling and emission tomography in the upcoming years are crucial for the usefulness of radioimmunoscintigraphy in daily practice.

Abstract
Cell suspensions prepared from lymph nodes, spleen or peripheral blood of patients with non-Hodgkin's lymphoma (NHL) often contain a high percentage of residual nonmalignant cellular elements. By E-rosette sedimentation, it was possible to enrich such suspensions from patients with various types of lymphoma for malignant cells. In patients with a B- or non-B/non-T-cell lymphoma, the neoplastic cells were found in the non-T fraction. The capacity to respond to stimulation by various stimuli was then confined to the T-cell fraction, which contained the residual normal T-cells. In patients with T-cell lymphomas, in which the malignant cells had retained the capacity to form E-rosettes, lymphoma cells were found in the T fraction. These cells usually did not respond to mitogenic stimuli. Using this separation method, small proportions of neoplastic cells could be identified in mixed cell populations. Thus, in the blood from nine out of 23 lymphoma patients without abnormalities in routine blood tests, a population of abnormal cells was detected after cell separation. This included a monoclonal B-cell population in the blood of four patients, a questionably monoclonal B-cell population in the blood of two patients and in increased non-B/non-T cell population in the blood of three patients.
