Cisplatin and 5-fluorouracil in refractory breast cancer patients: a phase II study.

24 patients with a median of 3 prior chemotherapy regimens were treated in our department with cisplatin 20 mg/m2 (with pre- and posthydration) and 5-fluorouracil 200 mg/m2 i.v. on day 1-5, every three weeks. 23 patients are evaluable; one had early death. 4 patients (17%) achieved a partial response, 8 had stable disease, and 11 progressed. Toxicity observed was moderate and no renal toxicity was noted. This study therefore shows tolerable toxicity but limited usefulness of adding cisplatin to 5-fluorouracil according to this schedule in these highly pretreated patients.

Adjuvant tamoxifen in primary breast cancer: influence on plasma lipids and antithrombin III levels.

The possible estrogenic effects of tamoxifen on plasma lipids and antithrombin III levels were investigated in 91 breast cancer patients. Mean values of total, HDL and LDL cholesterol, triglycerides, glucose, uric acid, and antithrombin III were evaluated in 55 patients on adjuvant tamoxifen for at least 3 months and compared with those found in 36 patients on no therapy. Total cholesterol, LDL cholesterol, and antithrombin III levels were significantly lower in treated patients (p less than 0.05). Our results support the hypothesis of a partial agonist action of this antiestrogen, although general clinical practice suggests that tamoxifen-related thrombotic events are rare.

Sequential administration of cyclophosphamide, methotrexate, 5-fluorouracil, and folinic acid as salvage treatment in metastatic breast cancer.

Experimental data show that sequencing methotrexate (MTX) and 5-fluorouracil (5-FU) may result in synergistic antitumor activity. Moreover, the effect of 5-FU is increased by folinic acid (FA), and finally, cyclophosphamide (CPA) produces an expansion of tumor growth fraction, suggesting an increased cytotoxic effect of cycle-specific drugs subsequently administered. Based on these premises, we have performed a Phase II study with CPA (600 mg/m2 i.v., day 1), MTX (200 mg/m2 1-h i.v. infusion, day 7), 5-FU (600 mg/m2 i.v., day 8), and FA (500 mg/m2 2-h i.v. infusion, day 8 plus 15 mg p.o. every 6 h on days 8 and 9) administered every 3 weeks. Thirty-six patients with metastatic breast cancer were admitted into the study. Median age was 52 years, and all but two patients were postmenopausal. Dominant sites of metastases were soft tissues in 10 patients, bones in 7 patients, and viscera in 19 patients. All patients were pretreated with chemo- and/or hormone therapy. Sixteen patients achieved an objective response (44.5%: 1 complete response and 15 partial responses), 8 had stable disease (SD) (22.2%), and 12 progressed (33.3%). Twenty-one patients had previously received conventional CMF in an adjuvant setting (15 patients) or for metastases (6 patients): 1 complete response (CR) and 7 partial responses (PR) were obtained in the first group and 1 in the second. Major toxic effects were hair loss (56.4%), nausea and vomiting (72%), mucositis (52.5%), and leukopenia (61%). A randomized study could be useful to assess the role of sequential CMF versus conventional CMF in metastatic breast cancer patients.

A phase II study with danazol in metastatic breast cancer.

Danazol is a synthetic steroid that inhibits the gonadotropin secretion. Its efficacy was tested in 27 patients with metastatic breast cancer at the dose of 200 mg three times daily. Characteristics of patients were as follows. The median age was 57 years (range, 44-85). All patients were postmenopausal, and all had previously received a median of two (range, 1-3) endocrine therapies. Estrogen receptor status was known in 12 (positive in five of 12; negative in seven of 12). Dominant sites of metastases were lung in seven, bone in ten, liver in three, and soft tissue in seven. Six of 27 patients were unevaluable for response (early death, four; lost to follow-up, two). Three of 21 patients showed an objective response, eight of 21 obtained stabilization of disease, and eight progressed. The therapy was well tolerated in the majority: gastric pain was observed in three and nausea in two. Danazol could have a role in the treatment of metastatic breast cancer as an alternative regimen when other treatment has failed.

Multimodality treatment of locally advanced breast cancer.

From 1976 to 1985, 61 consecutive patients with locally advanced breast cancer were treated with multimodality therapy. Overall 5-year survival was 30% with a median survival of 36 months. 50% of patients relapsed within 13 months. Other factors such as menopausal status, side of illness (right or left breast), responses to systemic or to local treatment, survival and progression-free survival in responders and non-responders have been analyzed.

Metastatic breast cancer: an analysis of prognostic factors in patients treated with aminoglutethimide.

An analysis of 127 women with metastatic breast cancer was carried out. All patients were treated with aminoglutethimide: of 117 evaluable patients, 29 responded, 46 remained stable and 42 progressed. A series of patients' characteristics were analyzed for their prognostic importance for response to this drug. The most important features able to predict response were found to be a previous response to tamoxifen and a long disease-free survival after mastectomy.

Leiomyosarcoma of the broad ligament: a case report and review of literature.

Leiomyosarcoma of the broad ligament is a rare tumor, since only 12 cases have been reported so far in the literature. A 53-year-old patient was diagnosed with leiomyosarcoma of the broad ligament at the Department of Gynecology Oncology of the National Cancer Research Institute in Genoa. The tumor had low mitotic activity and less than ten mitotic figures were found for ten high-power fields. The treatment consisted of total abdominal hysterectomy and bilateral salpingo-oophorectomy with bilateral ureteral neoanastomosis and omentectomy. The patient has not received either radiotherapy or chemotherapy, considering the low grade of malignancy, but she is only followed up on an outpatient basis. No evidence of metastasis has been noted after a follow-up of 13 months. It is concluded that low-grade leiomyosarcoma of the broad ligament should be treated only with surgery.

Salvage chemotherapy with paclitaxel in platinum-resistant advanced ovarian cancer patients.

Encouraging results with Paclitaxel are reported in ovarian cancer patients relapsing and progressing after platinum-based chemotherapy; however, the two populations have different probabilities of a response to a second-line treatment. Here we report the results achieved in 39 patients with platinum-refractory ovarian cancer, treated with Paclitaxel 175 mg/qm2 (or 135 mg/m2 if heavily pretreated) using 3-hour intravenous infusion every 3 weeks, in an attempt to verify the activity of this drug in platinum-resistant patients. The toxicity was mild to moderate and primarily hematologic and neurologic. The objective response rate is 12.8% with no complete responses. The response duration was brief and the median survival 6 (range 1-17) months. An accurate cost-benefit balance is necessary before routinely use of Paclitaxel in platinum-refractory patients. Further research is needed to determine the optimal role of Paclitaxel in the whole therapeutic strategy for ovarian cancer.

Paclitaxel plus ifosfamide in advanced ovarian cancer: a multicenter phase II study.

BACKGROUND: While ovarian cancer is one of the most sensitive cancers to cytotoxic drugs, with objective response rates of 60-80% routinely being reported in previously untreated patients, the majority of individuals with advanced disease ultimately relapse. Paclitaxel, a new and novel antimicrotubule agent, has shown activity as a salvage therapy in epithelial ovarian cancer. More importantly, in a prior study, it has been shown to be active in tumors that have displayed resistance to platinum compounds, with a reported response rate of 20%. Ifosfamide has shown activity in the treatment of patients who previously demonstrated clinical resistance to a platinum-cyclophosphamide combination. Recently, a synergistic activity of Taxol combined with ifosfamide has been reported in ovarian cell lines. Based on these data, a phase I/II study of a combination treatment with paclitaxel and ifosfamide was performed. PATIENTS AND METHODS: Thirty-one patients with recurrent ovarian cancer or ovarian cancer refractory to cisplatin (CDDP)-containing regimens were treated with paclitaxel at a dose of 135 mg/m2 on day 1; ifosfamide was administered at 1 g/m2 on days 2 and 3 for the first cycle and 1.5 and 2 g/m2 with the same schedule in cycles 2 and 3, respectively. In the absence of toxicity, the dose of ifosfamide was maintained at 2 g/m2 for the last three cycles. Cytotoxic therapy was repeated every 3 weeks. RESULTS: A 30% overall objective response rate was achieved in the 30 patients assessable for response. Among 21 platinum-resistant patients, 4 partial responses (19%) were observed, while in the 9 platinum-sensitive patients 2 complete responses and 3 partial responses (55%) were observed. Myelosuppression was the predominant toxicity. Leukopenia (WHO grade 3-4) occurred in 10% of patients who received ifosfamide at a dose of 1 g/m2 and in 18% of patients treated with ifosfamide at 1.5 g/m2. CONCLUSION: Our results confirmed a low activity of paclitaxel in platinum-resistant patients. The results of this combination treatment with paclitaxel-ifosfamide in our platinum-sensitive patients support further investigations in a randomized study of the combination regimen against paclitaxel alone or retreatment with organoplatinum compounds.

[Transvaginal echography in the evaluation of the grade of myometrial invasion in locally advanced endometrial carcinoma].

Neoplastic myometrial invasion is an important prognostic factor in local advanced endometrial carcinoma, conditioning therapeutic choice. In 34 patients with stage I and II endometrial carcinoma, the depth of myometrial invasion was evaluated by transvaginal sonography (TVS). In comparison with pathological findings, TVS showed an overall accuracy of 82.3% with a sensitivity of 82.6% and a specificity of 81.8%. The principal error was related to the underestimation of the lesion: negative predictive value of 49.2% vs positive predictive value of 90.4%. In conclusion, TVS is an accurate imaging method for staging of local advanced endometrial carcinoma.

Prognostic factors in node positive primary breast cancer patients treated with adjuvant CMF.

The influence of various patient and disease-related parameters on survival (S) and disease-free survival (DFS) in 217 node positive primary breast cancer patients treated with surgery followed by adjuvant i.v. cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) was evaluated by univariate and multivariate analyses. Five year actuarial S and DFS were 73.3% and 54.8%, respectively. Univariate analysis revealed that patient age, number of involved axillary nodes and ER status had a significant impact on both S and DFS. PgR positive tumors had improved DFS but no S difference was observed. Menopausal status predicted S but not DFS. Primary tumor size and CMF-induced amenorrhea did not predict disease outcome. Multivariate analysis demonstrated that only degree of nodal involvement and PgR status had independent significant impact on prognosis. Both S and DFS are significantly influenced by the number of involved nodes, whereas improved DFS but not S was evident in patients with PgR positive tumors.

Safety of conventional drugs and biologic agents for Rheumatoid Arthritis.

While initial researches documented that Rheumatoid Arthritis (RA) patients who took biologic agents had decreased symptoms with those receiving traditional treatment, safety of the drugs remains a concern. The authors in this paper review the safety of the RA new therapeutic approach utilizing biological agents and compare it with the safety of conventional disease-modifying anti-rheumatic drugs (DMARDs).

Systemic lupus erythematosus and renal involvement: which role of citokines expression?

The role of cytokines in systemic lupus erythematosus (SLE) glomerulonephritis is extremely complex. Proinflammatory molecules, such as TNF, IL-6, IL-1 and IL-18 are upregulated, as are both Thl and Th2 cytokines, with different implications: the local effects may be different from the systemic immunoregulatory ones. Excessive T helper cell function is a hallmark of SLE and abnormalities of Th citokine profiles have been implicated in loss of immune tolerance, increased antogenic load, defective B cell suppression and a variety of clinical manifestations. For some cytokines, TNF and IL-18 in particular, the local proinflammatory ones may be more relevant to the disease.

Chemotherapy with mitomycin-C, epidoxorubicin and vinblastine in CMF failing breast cancer patients.

Since most patients with breast cancer are treated with CMF as first line chemotherapy (usually in the adjuvant setting), schedules with alternative drugs are needed for the metastatic disease. In this study a new combination of Mitomycin, Epidoxorubicin and Vinblastine was employed in a group of 24 patients with metastatic breast cancer. A response rate of 37.5% was observed with a mild to moderate toxicity.

Continuous venous infusion of vindesine in metastatic breast cancer: experience with a subcutaneously implanted system and portable pump.

Fourteen patients with advanced pretreated breast cancer were treated with vindesine in continuous venous infusion (1.5 mg/sm/24 hours for 72 hours every 3 weeks). A totally implanted venous access and a portable pump were used. A total of 33 courses was administered. No objective response was observed and treatment was stopped. Drug-related toxicity consisted mainly of alopecia (64% of patients), nausea and vomiting (29%) and mucositis (29%). Catheter - related toxicity was observed in 6 patients (43%) and consisted of infection of the skin pocket in 4 patients and dislodging of the needle and catheter break in one patient. The feasibility of continuous venous infusion of vesicant drugs in outpatients is discussed.
