Paclitaxel-ifosfamide-carboplatin combination chemotherapy regimen in advanced uterine and adnexal malignant mixed Mullerian tumours.

BACKGROUND: Malignant mixed Mullerian tumours (MMMTs) of the uterus and adnexa represent aggressive gynaecologic malignancies with a high rate of loco-regional and distant failure. For that reason, we evaluated the paclitaxel-ifosfamide-carboplatin (TICb) combination in patients with advanced MMMTs. METHODS: Female patients with advanced MMMTs, WHO-PS 0-2, no prior chemotherapy for systemic disease, unimpaired haemopoietic and organ function were eligible. Chemotherapy was administered at the following doses; paclitaxel: 175 mg m(-2) on day 1, ifosfamide: 2.0 g m(-2) day(-1)--days 1 and 2, and carboplatin at a target area under the curve 5 on day 2, with prophylactic G-CSF from day 3. RESULTS: Forty patients of a median age 61 (45-72) years, performance status 0-2 with advanced MMMTs of the uterus (n=34), tubes (n=2) or ovary (n=4) have entered and all were evaluable for response and toxicity. Responses were as follows: 27 out of 40 (67.5%) evaluable patients responded, with 11 complete responses and 16 partial responses, while 10 had stable disease, and 3 developed progressive disease. The median response duration was 9 months (range, 4-40 months), median progression-free survival 13 months (range, 3-42 months), while median overall survival 18 months (range, 4-48 months). Grade 3/4 neutropenia was recorded in 22 out of 40 (55%)--with 13 developing grade 4 (≤7 days) and 7 out of 40 (17.5%) of patients at least one episode of febrile neutropenia. CONCLUSION: In this study, it appears that the TICb combination, yielded important activity with manageable toxicity in females with advanced MMMTs warranting further randomised comparison with current standard regimens.

Evaluation of the paclitaxel-ifosfamide-cisplatin (TIP) combination in relapsed and/or metastatic cervical cancer.

BACKGROUND: Recurrent or metastatic cervical cancer represents an aggressive malignancy with a high rate of locoregional and distant failure. Therefore, we evaluated the three-drug combination of paclitaxel-ifosfamide-cisplatin (TIP). METHODS: Systemic chemotherapy-naive patients with advanced metastatic/relapsed cervical cancer and a World Health Organization (WHO) performance status (PS) of 0-2 were eligible. TIP chemotherapy doses were paclitaxel 175 mg m(-2) on day 1, ifosfamide 2.5 g m(-2) on days 1+2, and cisplatin 40 mg m(-2) on days 1+2, with prophylactic granulocyte-colony stimulating factor. RESULTS: A total of 42 patients with recurrent/metastatic cervical cancer are evaluable for response and toxicity: median age: 56 (25-74) years; PS: 1 (0-2); histologies - squamous: 35, adenosquamous: 5, and adenocarcinoma: 2. Responses were overall response rate (RR): 62% (95% confidence interval (CI): 47.3-76.7%), with complete response (CR): 26% (95% CI: 12.7-39.3%), and partial response (PR): 36% (95% CI: 21.5-49.9%). Responses according to the relapse site were overall RR: 32% (95% CI: 13.7-50.3%) within previously irradiated pelvis vs 75% (95% CI: 57.7-92.3%) in extra-pelvic sites. Median time to progression (TTP) was 7 (range, 2-34+) months and median overall survival (OS) was 16.5 (range, 3-36+) months. Toxicities included grade 3-4 neutropenia: 83% (21% febrile neutropenia), grade 3-4 thrombocytopenia: 9%, no grade 3 neuropathy (35% grade 2), grade 2 asthenia/fatigue 15%, and no treatment-related deaths. CONCLUSION: TIP is an active regimen with acceptable toxicity in advanced/relapsed cervical cancer.

Docetaxel-ifosfamide combination in patients with advanced breast cancer failing prior anthracycline-based regimens: results of a phase I-II study.

The established clinical activity of docetaxel and ifosfamide as single agents in anthracycline pre-treated breast cancer, led us to conduct a phase I-II study to define the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and clinical activity of the docetaxel+ifosfamide combination in this setting. Patients with histologically confirmed metastatic breast cancer, after failure on prior anthracycline-based chemotherapy, were treated at successive dose levels (DLs) in cohorts of 3-6 with escalated doses of docetaxel 70-100 mg/m(2) over 1 h on day 1 followed by ifosfamide 5-6 g/m(2) divided over days 1+2 (2.5-3.0 g/m(2)/day over 1 h), every 21 days. G-CSF was added once dose-limiting neutropenia was encountered at a certain DL and planned to be incorporated prophylactically in subsequent higher DLs. Between March 1997 and December 2002, 65 patients with a median age of 57 years (range, 32-72) and performance status (WHO) of 1 (range, 0-2) were treated at 5 DLs as follows; 21 in phase I DLs (DL1: 3, DL2: 6, DL3: 3, DL4: 6, and DL5: 3) and the remaining 44 were treated at DL4 (total of 50 patients at DL4), which was defined as the level for phase II testing. All patients were assessable for toxicity and 62 for response. DLT (with the addition of G-CSF after DL2) was reached at DL5 with 2/3 initial patients developing febrile neutropenia. Clinical response rates (RRs), on an intention-to-treat basis, in phase II were: 56%; (95% CI, 42.2-69.7%); 4 CRs, 24 PRs, 10 SD and 12 PD. The median response duration was 7 mo (3-24 mo), median TTP 6.5 mo (0.1-26 mo), and median OS 13 mo (0.1-33 mo). Grade 3/4 toxicities included: neutropenia in 72% of patients, with 60% developing grade 4 neutropenia (

HER-2/neu status of primary breast cancer and corresponding metastatic sites in patients with advanced breast cancer treated with trastuzumab-based therapy.

BACKGROUND: The aim of this prospective study was to investigate whether there were changes in HER-2/neu status in newly-developed metastatic lesions following treatment with trastuzumab in advanced breast cancer patients overexpressing HER-2/neu. The utility of serological assays for HER-2/neu in such patients was also studied. PATIENTS AND METHODS: Sixteen patients with HER-2/neu-overexpressing tumors (15 were 3+ by immunohistochemistry (IHC) and one 2+ by IHC and positive by the chromogenic in situ hybridization (CISH) test) were included in the study. Fourteen patients underwent biopsy and 2 patients fine-needle aspiration (FNA) of newly-developed metastatic lesions following trastuzumab treatment. All samples were assayed for HER-2 by IHC and by the CISH test. Serial serum HER-2/neu (S-HER-2) levels were measured prior to (baseline values) and during trastuzumab-based treatment by enzyme-linked immunosorbent assay (ELISA) (cut-off point: 10 ng/ml) in all patients. The patients were divided into 2 groups: those with "altered HER-2/neu status" and those with "conserved HER-2/neu status" in the metastatic region. RESULTS: Six out of the 16 (37%) ("altered HER-2/neu status") newly-developed metastatic lesions lost their HER-2/neu overexpression and scored 0 or +1 by IHC or negative on the CISH test, while in the remaining cases (10/16, 62.5%) ("conserved HER-2/neu status"), the HER-2/neu status was unchanged (+3 by IHC or a positive CISH test). Baseline S-HER-2 levels were elevated in 5 out of 16 patients (3 of "altered HER-2/neu status", 2 of "conserved HER-2/neu status"). The serum HER-2 (S-HER-2) levels declined and returned within the normal ranges in all these 5 patients as a response to trastuzumab treatment. Following the disease progression, the S-HER-2 levels of the 3 patients with "altered HER-2/neu status" remained normal, while those of 2 with "conserved HER-2/neu status" increased. There was no statistically significant difference in the number of chemotherapeutic treatments or the median time of treatment with trastuzumab or chemotherapy between the 2 groups. Time to tumor progression (TTP) was significantly shorter in the "altered HER-2/neu status" patients (median TTP for "altered HER-2/neu status": 9.5 months, and for "conserved HER-2/neu status": 12 months; p <0.001). CONCLUSION: These data suggest that, for most patients with metastatic breast cancer treated with trastuzumab, the HER-2/neu expression as measured by IHC and/or CISH in newly-developed metastatic lesions was unchanged. However, a remarkable percentage of cases lost HER-2/neu overexpression. It is not clear whether this finding implies resistance or sensitivity to trastuzumab.

Dose escalation of docetaxel and ifosfamide in patients with advanced breast cancer failing prior anthracyclines: mature results of a phase I-II study.

PURPOSE: Single-agent docetaxel and ifosfamide are clinically active in anthracycline-pretreated advanced breast cancer. We conducted a phase I-II study aiming to define the maximum tolerated dose (MTD), the dose-limiting toxicities (DLTs), and the activity of the docetaxel-ifosfamide combination in this setting. PATIENTS AND METHODS: Cohorts of 3-6 patients with histologically confirmed metastatic breast cancer after prior anthracycline-based chemotherapy were treated at successive dose levels (DLs) with escalated doses of docetaxel (70-100 mg/m(2) over 1 h on day 1), followed by ifosfamide 5-6 g/m(2) divided over days 1 and 2 (2.5-3.0 g/m(2)/day over 1 h), and recycled every 21 days. G-CSF was added once dose-limiting neutropenia was encountered at a certain DL and planned to be incorporated prophylactically in subsequent higher DLs. RESULTS: Sixty-five patients (median age 57 years, range 32-72) and performance status (PS) (World Health Organization-WHO) of 1 (range 0-2) were treated at 5 DLs as follows: 21 in phase I DLs (DL1: 3, DL2: 6, DL3: 3, DL4: 6, and DL5: 3) and the remaining 44 were treated at DL4 (total of 50 patients at DL4), which was defined as the level for phase II testing. All patients were evaluable for toxicity and 62 for response. DLT (with the addition of G-CSF after DL2) was reached at DL5 with 2/3 initial patients developing febrile neutropenia. Clinical response rates (RRs), on an intention-to-treat basis, in phase II were 56% (95% CI 42.2-69.7): complete remission (CR) 4, partial remission (PR) 24, stable disease (SD) 10 and progressive disease (PD) 12. The median response duration was 7 months (range 3-24), the median time to progression (TTP) 6.5 months (range 0.1-26), and the median overall survival (OS) 13 months (range 0.1-33). Grade 3/4 toxicities included neutropenia in 72% of patients-with 60% developing grade 4 neutropenia (

Temozolomide in combination with docetaxel in patients with advanced melanoma: a phase II study of the Hellenic Cooperative Oncology Group.

PURPOSE: Temozolomide is a novel oral alkylating agent that is effective against melanoma. Moreover, temozolomide readily crosses the blood-brain barrier and may consequently be effective in patients with brain metastases. This phase II study was performed to assess the efficacy and safety of the combination regimen of temozolomide and docetaxel in patients with advanced metastatic melanoma. PATIENTS AND METHODS: Sixty-five patients with metastatic melanoma were enrolled. Treatment consisted of intravenous docetaxel (80 mg/m(2)) on day 1 and oral temozolomide (150 mg/m(2)) on days 1 to 5, every 4 weeks, for a maximum of six cycles. RESULTS: Sixty-two patients were eligible for the efficacy and safety analysis. Seventeen patients (27%) achieved an objective response, including five complete (8%) and 12 partial responses (19%). Median response duration was 9.5 months. Among responders, median time to progression (TTP) was 11.2 months and median overall survival (OS) was 16 months. For all treated patients, the median TTP was 4 months and median OS was 11 months. Three (38%) of eight patients who presented with brain metastases had a partial response for 5, 6, and 12 months. Of 52 patients who did not have brain involvement at presentation, only four (8%) developed brain metastases at a median follow-up of 14 months. Myelosuppression was the primary toxicity. CONCLUSION: The combination of temozolomide and docetaxel was effective and well tolerated as first-line treatment for patients with advanced metastatic melanoma and demonstrated encouraging antitumor activity against brain metastases.

Phase II study of temozolomide in heavily pretreated cancer patients with brain metastases.

PURPOSE: To determine the efficacy, tolerability, and safety of temozolomide in heavily pretreated patients with solid tumors and brain metastases. PATIENTS AND METHODS: Twenty-seven of twenty-eight enrolled patients with brain metastases from solid tumors received temozolomide (150 mg/m2/day for five days every 28 days). Twelve patients had non-small-cell lung cancer, five patients had small-cell lung cancer, four patients had breast cancer, and seven patients had other solid tumors. The majority of the patients had multiple metastatic sites, a poor performance status, and had been heavily pretreated. The primary end points were objective response rate, time to progression, and overall survival. Secondary end points included safety and tolerability, and neurologic performance status. RESULTS: A partial response was achieved in 1 (4%) of 24 evaluable patients. Disease stabilization was observed in four (17%) patients. Overall median survival was 4.5 months and median time to progression was 3 months. Improvements in clinical neurologic status were achieved in 10 (37%) patients. Treatment with temozolomide was well tolerated. Four patients had grade 3 nausea and vomiting. No grade 4 toxicity or treatment-related deaths were observed. CONCLUSIONS: Temozolomide demonstrated encouraging activity in the treatment of brain metastases in heavily pretreated patients with solid tumors, and was safe and well tolerated.

Diffuse large cell lymphomas: identification of prognostic factors and validation of the International Non-Hodgkin's Lymphoma Prognostic Index. A Hellenic Cooperative Oncology Group Study.

Several clinical prognostic factors have been identified that predict treatment outcome in patients with diffuse large cell lymphomas. An International Non-Hodgkin's Lymphoma Prognostic Index (IPI) has been recently formulated. We tried to identify the clinical prognostic factors that predict treatment outcome in Greek patients with diffuse large cell lymphomas and validated the IPI in these patients. The possible prognostic variables for tumor response, relapse-free (RFS) and overall survival (OS) were analyzed in 239 consecutive patients treated with anthracycline-based chemotherapy regimens. In univariate analysis, factors associated with poor response were stages III-IV, performance status (PS) >/=2, spleen and bone marrow involvement, more than one extranodal site involved, increased lactate dehydrogenase (LDH) value, hemoglobin (Hb) <12 g/dl, albumin <3.5 g/dl, erythrocyte sedimentation rate (ESR) >50 mm/h. Multivariate analysis identified stage, PS, more than one extranodal site involved, increased LDH level, and ESR > 50 mm/h as the factors more predictive of poor response. For RFS, multiple Cox analysis found stages III-IV and bone marrow involvement to be statistically significant. For OS, multiple Cox analysis identified stage III-IV, PS >/=2, bone marrow involvement, more than one extranodal site involved, increased LDH level and ESR > 50 mm/h as negative prognostic factors. Patients stratified in the different risk groups of the IPI had a significantly different outcome regarding complete response (CR) rate, RFS and OS. In conclusion, although age >60 years was not recognized as an adverse factor in this analysis, our patients stratified in the different groups of the IPI had significant differences in CR rate, 2-year RFS and OS verifying the prognostic significance of the index. Bone marrow involvement and ESR > 50 mm/h, parameters that are not included in the IPI, adversely affected survival.

A prospective randomized phase III study in non-small-cell lung cancer comparing cisplatin, ifosfamide, vinblastine (VIP) versus cisplatin, ifosfamide and etoposide (VIP-16). Hellenic Co-Operative Oncology Group.

BACKGROUND: It was recently reported that when ifosfamide was added to cisplatin and vinblastine the response rate was increased but not the survival in patients with non-small-cell lung cancer (NSCLC). The purpose of this study was to investigate the possibility of increased responses and survival with use of the combination of cisplatin, ifosfamide, etoposide (VIP-16) in comparison to the combination of cisplatin, ifosfamide, vinblastine (VIP) in non-operable NSCLC. PATIENTS AND METHODS: Two hundred twelve patients with histologically confirmed diagnoses of NSCLC were randomized into two groups: group A received cisplatin 100 mg/ m2, vinblastine 6 mg/m2 and ifosfamide 3 mg/m2 i.v. on day 1 every 3 weeks; group B received the same regimen except that etoposide 120 mg/m2 was substituted for vinblastine on days 1, 2, and 3. Patients were well balanced for age, sex, performance status (PS), stage, grade, histology and sites of disease, and the relative dose intensity was similar in both groups. RESULTS: One hundred one patients were evaluable for response in group A and 99 in group B. The overall response rates were 29% in group A (5CR) and 25% in group B (3CR). The median time to progression was 7.51 (2-35) months for group A and 7.7(1-28) months for group B (P = 0.34). The median survival was 8.49 (0.33-37.44) months for group A and 9.38 (0.43-36.59) for group B (P = 0.39). Multivariate Cox stepwise analysis showed stage to be the only significant prognostic factor for survival (P = 0.0114). Toxicity was not remarkable and not different between the two groups except for alopecia which was much more common in the patients who received etoposide. CONCLUSION: VIP and VIP-16 combination chemotherapies are equally active in NSCLC with acceptable toxicity. Stage proved to be the most significant prognostic factor for survival in this study.

Comparison of ondansentron (GR 38032F) versus ondansentron plus alprazolam as antiemetic prophylaxis during cisplatin-containing chemotherapy.

The purpose of our study was to evaluate the effectiveness of alprazolam (APZ) as an adjuvant drug to ondansentron against cisplatin-induced emesis. All patients received CDDP 100 mg/m2, and had previously received chemotherapy. We established two groups of patients randomly: Group A patients received 5-HT3 alone, and Group B received 5-HT3 and APZ. The drugs were administered as follows: 5-HT3 was given at a dose of 1 ampule 8 mg in 100 ml N/S in 10 minutes i.v. infusion before the infusion of CDDP. We continued with 1 tablet 8 mg in the afternoon and 1 before sleeping the first day; for the next two days, patients received 3 tablets 8 mg/day. APZ was given in tablets of 0.25 mg 60 minutes before CDDP infusion and then with the second and third dose of 5-HT3. We did not find significant differences in clinical parameters and factors, especially anxiety, that influenced vomiting between the examined groups. The mean number of vomiting episodes without gastric content (4.76 episodes) and the mean duration of nausea (195 minutes), were greater in Group A than in Group B (1.39 episodes, p < .0001; 91 minutes, p < .049). Differences also were found in the mean number of vomiting episodes with gastric content between the examined groups (A: 1.97; B: 1.09; p < .135). The intense of nausea and vomiting according to WHO classification was greater in Group A (grade 0, p < .004; grade 2, p < .020) than in Group B. Patients of Group B had fewer problems with appetite (p < .027), and more intense sedative effect (grade 0 [p < .001], 1 [0.027], 2 [0.022]) than patients of Group A. In conclusion APZ improved the antiemetic efficacy of ondansentron in cisplatin-induced emesis.

Treatment of renal cell carcinoma with escalating doses of alpha-interferon.

Forty-one patients with advanced renal cell cancer started treatment with recombinant alpha-interferon intramuscularly, beginning at a dose of 5 x 10(6) U x 3/week, progressively increasing doses every week, from 5 x 10(6) U x 3/week to 10 x 10(6) U x 3/week, to the highest dose of 15 x 10(6) U x 3/week. No complete response was achieved, partial response was achieved in 6 (13%) patients with a median duration of 45.2 (13-134) weeks. The majority of side effects from interferon treatment evaluated according to WHO classification were seen during the first 2 months and they were fever (after interferon administration) in 95% patients, chills (51%), flu like syndrome (65%), fatigue (87%), anorexia (80%), worsening in performance status (56%), nausea and vomiting (19%), weight loss (> 10% during therapy) (26%), leukopenia (14%), anemia (75%), neurological symptoms (43%), psychological symptoms (19%) and dyspnea (9%). The results are similar to other studies and toxicity was only moderate.

First-line combination chemotherapy with mitoxantrone, methotrexate, vincristine and carboplatin (MIMOC) in advanced breast cancer.

51 patients with stage IIIB and IV breast cancer entered a prospective phase II study of combination chemotherapy that consisted of mitoxantrone (8 mg/m2) day 1, methotrexate (25 mg/m2) day 1, vincristine (1 mg/m2) day 2 and carboplatin (250 mg/m2) day 2 (MIMOC) given in a 3-weekly schedule. None had received prior chemotherapy for metastatic disease, although 16 patients were given adjuvant chemotherapy. Objective response to treatment was seen in 29 of 48 patients analysed for response (60%) with 8 complete responses (CR). 7 out of 8 patients with stage IIIB disease responded, 2 of them completely. Responses were seen in all sites but the best results were achieved in lung metastases with 50% CR. The median duration of response was 8 months and the median time to disease progression was 12 months. The main toxicity was nausea and vomiting which was severe in 20% of the patients. Other toxicities were mild. MIMOC was administered on an out-patient basis and appears to be effective as first-line treatment in advanced breast cancer.

The prognostic significance of immune changes in patients with renal cell carcinoma treated with interferon alfa-2b.

PURPOSE: To evaluate the response rate and the immunorestorative properties of subcutaneously administered interferon alfa-2b (IFN-A2b) in patients with advanced renal cell carcinoma (RCC) and to correlate the immune status with the clinical responses. PATIENTS AND METHODS: Twenty-six patients with advanced RCC were treated with recombinant IFN-A2b. The dose was increased progressively from 5 x 10(6) IU the first week to 10 x 10(6) IU the second week, and thereafter to 15 x 10(6) IU subcutaneously. RESULTS: Four patients (15%) achieved partial responses (PRs), and five patients (19%) had stable disease (S), whereas 17 patients (65%) progressed. In all patients, blood was withdrawn before IFN treatment and monthly thereafter. T lymphocytes after isolation from peripheral blood were tested for proliferation in the autologous mixed lymphocyte reaction (autoMLR) and allogeneic mixed lymphocyte reaction (alloMLR), interleukin-2 (IL-2) production, expression of IL-2 receptors during the alloMLR, and the production of interleukin-1 (IL-1) by peripheral-blood monocytes. Twelve patients were assessable, four patients had a PR, one patient had S, and seven patients had progressive disease. Striking increases were demonstrated in all parameters 1 month after treatment with IFN-A2b in the four patients who responded and the patient with S. Namely, the autoMLR responses showed a mean increase of 250%, the IL-2 production 247%, the expression of IL-2-specific receptors 446%, the alloMLR responses 160%, and the production of IL-1 262%. On the contrary, the nonresponders did not show any change in their overall immune status, and in some, deterioration of the already depressed immunologic functions was observed. CONCLUSIONS: Administration of IFN-A2b results in a marked potentiation of deficient cellular immune response in vitro in those patients with RCC who respond to the treatment. This may have prognostic significance, and certainly more patients are required to be studied for definite conclusions.

A randomized prospective study of cisplatin and vinblastine versus cisplatin, vinblastine and mitomycin in advanced non-small cell lung cancer.

From June 1986 to February 1989, 103 patients with advanced non-small cell lung cancer, with no previous chemotherapy, were randomized to receive either a combination of cisplatin and vinblastine (group A) or the same combination with the addition of mitomycin (group B). In group A, 15/48 evaluable patients had objective responses, as did 8/45 in group B. The median survivals were 35 and 32 weeks, respectively. The median survival of patients with response or stable disease was 43 weeks. Response and survival did not differ significantly between treatment groups. The addition of mitomycin to the two-drug combination showed no major therapeutic benefit, while bone marrow toxicity was increased. Three patients in group B died of sepsis. Among the different patient characteristics, disease stage, performance status and response had influence on survival.

A randomized trial of the effect of three non-steroid anti-inflammatory agents in ameliorating cancer-induced fever.

Paraneoplastic fever is well known, and is not an uncommon problem in daily practice. In an effort to ameliorate tumour-induced fever we randomized 48 patients to receive three different non-steroid anti-inflammatory drugs: Naproxen (500 mg d-1), Indomethacin (75 mg d-1) or Diclophenac sodium (75 mg d-1). All patients had solid tumours, and microbial infection had been excluded. All three drugs were equally effective in bringing the temperature down to normal for a period of 30-33 d. Naproxen had the most rapid effect. In cases of fever relapse with the first drug, when the other two drugs were given instead, both proved equally effective. No side-effects were observed. We conclude that Naproxen, Indomethacin and Diclophenac sodium are equally effective in ameliorating paraneoplastic fever. In relapse, a second drug given subsequently can be effective as well.

Concomitant administration of 4-hydroxypyrazolopyrimidine (allopurinol) and high-dose continuous infusion 5-fluorouracil.

We tried to study the protection of allopurinol (HPP) from the toxicity of 5-fluorouracil (5-FU). A total of 29 patients received 74 cycles of chemotherapy (16 colon adenocarcinomas, 7 head and neck, 3 breast cancers and 3 cancers of pancreas). HPP was given 900 mg/day p.o. 4 days prior to treatment, and continued with same dose throughout the course of 5-FU and for 12 days after completion of the treatment. 5-FU was administered in 24 hour intravenous infusions on days 1-5 (dose range 900-1,200 mg/m2/day). 5-FU was given alone or in combination with mitomycin-C 10 mg/m2/day (1st day), epirubicin 40 mg/m2/day (1st, 2nd day), cis-platinum 120 mg/m2/day (1st day). In comparison with other studies the toxicity was limited. We conclude that HPP can diminish the side effects, especially myelosuppression, allowing an increase in the maximum tolerated dose of 5-FU; even if combined with other cytostatic drugs. Control studies must be done to confirm our observations.

Association of neutrophil alkaline phosphatase activity and glycosylated haemoglobin in diabetes mellitus.

We determined neutrophil alkaline phosphatase (NAP) activity in diabetic patients in conjunction with HbA1c levels. NAP was estimated using semiquantitative cytochemical technique, and we studied its activity in different groups of diabetic patients. We found that NAP score is correlated with the HbA1c level. Non-diabetic patients were used as controls, in whom NAP score and HbA1c were found normal. In diabetic patients the NAP activity and the HbA1c level were altered similarly during the various phases of the disease. Our findings indicate that NAP score could be used as a simple new parameter for diabetes. The pathophysiologic mechanism of our observations needs further investigation.

Combination chemotherapy with prednimustine, adriamycin, vincristine (VAP) in advanced breast cancer. A phase II study.

The purpose of this study was to evaluate VAP combination chemotherapy in advanced breast cancer: prednimustine 80 mg/m2 p.o. days 1-5, adriamycin 40 mg/m2 and vincristine 1.4 mg/m2 1st day in cycles of 3 weeks. Twenty-one women entered the study and 19 were evaluable. The mean age was 54.5 years (25-69) with an average performance status of 60 according to Karnofsky. Hormonal receptors were unknown in 10, positive in 6 and negative in 3. The dominant site of disease was soft tissues in 11, bones in 1, liver in 3 and lung in 4. Fourteen patients had as prior treatment cyclophosphamide, methotrexate and 5-fluorouracil (CMF), two had tamoxifen and three none. Ten patients (52.6%) had a partial response with a mean survival of 7.8+ months, 5 patients (26.3%) had stable disease with a mean survival 6.6+ months and 4 patients (21.1%) had progressive disease with a mean survival of 3 months. Regarding toxicity all patients had alopecia, most of the patients had nausea grade I, whereas 5 patients developed mild leukopenia. We conclude that VAP is an effective, well tolerated chemotherapy combination in patients with advanced breast cancer which deserves further clinical trials.

Stenosis of the colon in pancreatitis.

Persistent or transient stenosis of the colon is a rare complication in the course of acute or chronic pancreatitis. The clinical, laboratory and surgical findings are discussed. Two cases are described here, and 34 cases reported in the literature are reviewed.
