Phase II study of weekly mitoxantrone, 5-fluorouracil, and leucovorin in metastatic breast cancer.

A phase II study to test the toxicity and the efficacy of a weekly combination of Mitoxantrone, 5-Fluorouracil and L-Leucovorin (MFL) was carried out in 43 patients with metastatic breast cancer. Chemotherapy consisted of mitoxantrone 4 mg/m2, 5-fluorouracil 375 mg/m2, and L-leucovorin 100 mg/m2 on day 1, weekly. Patient characteristics were: median age 53 years (range 36-65); estrogen receptor (ER) status was known in 26 patients and of these 15 (57.7%) patients were ER-positive and 11 (42.3%) ER-negative. Of the 43 patients, 25 (58.1%) and 18 (41.9%) patients had received prior adjuvant chemotherapy and prior adjuvant endocrine treatment, respectively. MFL was administered to 22 (51.1%) patients as first line chemotherapy for advanced disease, while 21 (48.9%) patients had received 1 to 2 cytotoxic regimens for metastatic disease. The dominant sites of metastases were: soft tissue in 11 (25.5%) patients, bone in 8 (18.6%) patients and viscera in 24 (55.9%). All patients were assessable for toxicity: only 8 patients experienced WHO grade 3 leukopenia. Thrombocytopenia, diarrhea, stomatitis, and nausea/vomiting were negligible. Anemia and alopecia were not observed. Thirty-nine patients were assessable for response: overall response rate was 28.2% (complete response 7.7% and partial response 20.5%). Median duration of response was 12 months (range 6-34). Patients with no prior anthracyclines had a 42.1% response rate compared to 15% in patients who had received anthracyclines. Median overall survival of the 43 patients was 6 months (range 1-34). Weekly MFL is a well-tolerated and a moderately effective regimen for the treatment of metastatic breast cancer.

Calf myopathy with a twist.

The traditional clinical criteria for identifying a manifesting Duchenne carrier are a positive family history, proximal limb weakness, calf hypertrophy, high serum creatine kinase. We describe a 52-yr-old woman with history of 1 1/2 yr of progressive wasting and weakness of the left calf and marked elevation of serum creatine kinase. Although her quadriceps was clinically silent, it showed mild alterations on ultrasound, computerized tomography and biopsy, and some abnormalities in dystrophin immunostaining, suggesting a manifesting carrier of the dystrophin gene. Given the enormous variability of manifestations of the Duchenne variant in females, we suggest that great care must be exercised in ruling out this genetic disorder.

Randomized study comparing chemotherapy plus radiotherapy versus radiotherapy alone in FIGO stage IIB-III cervical carcinoma. GONO (North-West Oncologic Cooperative Group).

Between January 1989 and December 1991, 64 patients with advanced cervical carcinoma FIGO stage IIb-III were randomized to receive radiotherapy (RT) alone or the sequential combination of chemotherapy (CT) and RT. RT consisted of external RT (40 Gy fractionated over 4 weeks)+brachy-therapy (40 Gy to point A)+an additional boost to the parameters (15-20 Gy) in arm RT; CT consisted of cisplatin 60 mg/m2 i.v. day 1 q 15 days administered for 2 cycles before the start of RT and for 4 cycles after the end of radiation treatment in CT+RT arm. Among the 58 evaluable patients objective response rate was as follows: in RT arm, CR in 40.7% of patients, PR in 40.7%, and SD in 18.6%; in CT+RT arm, CR in 42% of patients, PR in 35.5%, and SD in 22.5%. The median duration of response was 12 months (range: 3-38 + months). At a median follow-up of 36 months survival (S) and progression-free survival (PFS) were 83% and 72.4% in RT arm, 72% and 59.3% in CT+RT arm, respectively. No significant difference was observed between the 2 treatment arms, neither in terms of objective response nor in terms of S and PFS. Both treatments were generally well tolerated. In our experience the addition of chemotherapy to standard radiotherapy does not enhance morbidity and does not interfere with the correct delivery of the planned treatment. However, results of this combined modality regimen remain unsatisfactory, since no improvement in pelvic control and survival of patients with advanced cervical carcinoma was observed.

Non-radioactive detection of 17p11.2 duplication in CMT1A: a study of 78 patients.

Charcot-Marie-Tooth disease type 1 (CMT1) is a peripheral neuropathy characterised by progressive distal muscular atrophy and sensory loss with markedly decreased nerve conduction velocity, mostly inherited as an autosomal dominant trait. The most common form, type 1A, is associated with a 1.5Mb DNA duplication in region p11.2-p12 of chromosome 17 in many patients. In this study a non-radioactive test for detection of the CMT1A duplication based on an RM11-GT microsatellite polymorphism is presented. Although different methods have been devised for this purpose, the present method has the advantage of being rapid, informative, economical, easily interpretable, and, therefore, it represents a very useful tool for diagnosis of CMT1A, especially before clear manifestation of clinical symptoms. Seventy-eight patients diagnosed clinically as having CMT and evaluated by electrophysiological methods were tested with an RM11-GT microsatellite and with probe pVAW409R3. The CMT1A duplication was found in 76% of the 56 unrelated patients. RM11-GT was the most informative marker with a heterozygosity of 89%.

Ondansetron and dexamethasone versus standard combination antiemetic therapy. A randomized trial for the prevention of acute and delayed emesis induced by cyclophosphamide-doxorubicin chemotherapy and maintenance of antiemetic effect at subsequent courses.

The antiemetic efficacy of ondansetron and dexamethasone (Ondex) was randomly compared to that of high-dose metoclopramide, dexamethasone, and orphenadrine (Control) in the prevention of emesis induced by cyclophosphamide-doxorubicin chemotherapy in 64 chemotherapy-naive breast cancer patients. For the control of acute emesis (day 1), patients were randomized to receive either ondasetron 8 mg p.o. 1 hour prior to chemotherapy (CT) and repeated after 6 and 12 hours plus dexamethasone 20 mg i.v. 40 minutes prior to CT (Ondex) or dexamethasone 20 mg i.v. 40 minutes prior to CT, orphenadrine 40 mg i.m. 35 minutes prior to CT and metoclopramide 3 mg/kg i.v. 30 minutes prior to CT and repeated after 90 minutes followed by 40 mg p.o. every 3 hours for 4 times (Control). To control delayed emesis, patients on Ondex received ondansetron 8 mg PO t.i.d. days 2 and 3 and patients in the Control arm received metoclopramide 0.5 mg/kg p.o. q.i.d. and dexamethasone 8 mg i.m. b.i.d. days 2 and 3. Complete and major control of acute emesis was observed in 74%/94% and 44%/67% of patients treated with Ondex and Control, respectively (p < .01/p < .005). Acute nausea was absent in 38% and 34% of patients treated with Ondex and Control, respectively (p = NS). Complete and major control of delayed emesis (days 2-5) was observed in 65%/91% versus 44%/66% of patients in the Ondex and Control arms, respectively (p = NS/p < .01). In patients receiving 6 courses of FEC/FAC, control of acute emesis was significantly superior with Ondex at all treatment courses.

Cerebral metastases secondary to ovarian cancer: still an unusual event.

An incidence of cerebral metastases secondary to epithelial ovarian cancer as high as 11.6% has been reported in small series and related to the prolonged survival of ovarian cancer patients treated with platinum compounds (Hardy, J. R., and Harvey, V. J. Gynecol. Oncol. 33, 296-300, 1989). A review of the histories of 413 ovarian cancer patients, treated from 1981 to 1989 with platinum-based combination chemotherapy according to the protocols of the Gruppo Oncologico Nord Ovest (GONO) (North West Oncology Group), showed that only 9 patients (2.2%) developed clinical evidence of cerebral metastases. Six of 9 patients had FIGO Stage IIIc disease and 1 each with FIGO Stages Ic, IIc, and IV. All these patients had received cisplatin or carboplatin-based combination chemotherapy. Clinical response to initial cytotoxic therapy was as follows: complete response, 3 patients; partial response, 4 patients; stable disease, 1 patient; progressive disease, 1 patient. Cerebral metastases occurred at a median of 19 months (range 3-36) from diagnosis and median survival of patients with central nervous system (CNS) metastasis was 26 months (range 10-81) from diagnosis of primary disease and 8 months (range 1-45) from diagnosis of CNS involvement. The incidence of CNS metastases in our series is similar to that reported in the past and significantly lower than figures reported by the above mentioned paper. On the basis of our data we do not agree with Hardy and Harvey about the relationship possibly existing between prolonged survival and incidence of CNS metastases and, particularly, about the need for prophylactic cranial irradiation.

Spine surgery in spinal muscular atrophy: long-term results.

Fifteen patients with spinal muscular atrophy operated on for scoliosis were reviewed and interviewed. Age at time of surgery averaged 16 yr. Follow-up averaged more than 5 yr. Eleven patients underwent posterior spinal fusion with Luque instrumentation. Four had Harrington instrumentation, with segmental wiring in three. Three out of the 15 also had anterior fusion with Dwyer instrumentation. Patients were immobilized in cast or brace for 6 months, on average, after surgery. The average curve correction was 50%. There was a loss of vital capacity after the operation, which in most cases was regained with time. In functional terms, there were improvements and deteriorations both in the short and long term. Esthetic appearance improved in all patients, as did the perceived well-being. Retrospectively all but one would have the operation again.

Lymphoblastoid interferon in advanced breast cancer: a phase II study.

Thirty-two metastatic breast cancer patients entered a phase II study in order to evaluate the toxicity and the clinical activity of lymphoblastoid interferon (IFN). The treatment was divided into two phases, induction and maintenance. During the first, patients were submitted to lymphoblastoid IFN at the dose of 3 MU die intramuscularly for 4-8 weeks; during maintenance treatment IFN was given at the same dosage, intramuscularly, every other day until progression. Five patients with inadequate follow-up were excluded from disease evaluation, thus 27 patients were evaluable for response. No complete response was observed; one patient achieved a partial response and 15 patients disease stabilization. Median time to progression in patients with partial response or stable disease was 11 weeks (range 2-32). Five patients with soft tissue metastases were biopsied before and after 1-2 months of treatment in order to perform Labelling Index and hormonal receptor status determinations. No significant modification was observed.

Cisplatin-based chemotherapy in recurrent or high risk ovarian granulosa-cell tumor patients.

Nine chemotherapy-naive women with recurrent (2 patients) or high risk factors (bilateral or extraovarian spread, poorly-differentiated tumor, age > or = 40 years at diagnosis, residual disease after surgery) granulosa-cell tumors were treated with cisplatin, cyclophosphamide with or without doxorubicin (PAC, PC) or cisplatin, etoposide and bleamycin (PVP-16B). Toxicity was acceptable and the most frequently encountered adverse reactions were WHO grade 3 gastrointestinal toxicity in 77% of patients, and grade 3 myelosuppression in 22% of cases. Clinical complete response was achieved in the 2 patients with recurrent disease. Five patients underwent second look surgery which documented: complete response in 3 patients, partial response in 1 patient and progressive disease in 1 case. Median survival was 85 months (range 14-103). Cisplatin-based cytotoxic regimens may be of benefit in the treatment of recurrent or high risk granulosa-cell tumors.

Serum CEA, CA 15-3, and MCA in breast cancer patients: a clinical evaluation.

With the aim of investigating the clinical usefulness of CEA, CA 15-3, and MCA serum levels, we studied 143 women whose breast cancer was submitted to serial tumor marker determinations: 79 women had stage I-II tumors and were undergoing follow-up after local and adjuvant treatment; 64 women presented metastatic lesions. Among the stage I-II patients, 63 women remained disease-free during the observation period and 16 developed metastases. In 13 out of 16 patients, tumor markers were elevated and in 11 out of 16 patients the increased tumor markers were the first sign of disease progression. Among metastatic patients, 49 presented increased tumor markers and 15 normal value. Moreover, we observed a decrease or normalization of tumor markers in patients responding to treatment and increased values in progressive disease. No correlation was noted between site of disease and tumor markers. We concluded that tumor markers are of clinical value in the detection of metastasis and may be useful in monitoring response to treatment in metastatic patients.

Epidemiology of neuromuscular disorders in the under-20 population in Bologna Province, Italy.

A retrospective epidemiological survey of the principal neuromuscular disorders was undertaken in the population under the age of 20 yr in Bologna city and province. The incidence of Duchenne muscular dystrophy (DMD) proved to be 25.8 x 10(-5), that is, comparable with the outcome of neonatal screening studies. The incidence of spinal muscular atrophy (SMA) was very high (11.2 x 10(-5), probably the result of our greater awareness and recognition of this disorder. The prevalence of neuromuscular disorders in the 0-19 yr population is 1.5 times that in the general population; that of DMD is 28 x 10(-5) vs 6.3 x 10(-5) and that of the SMA 6.5 x 10(-5) vs 1.2 x 10(-5). Our results indicate that neuromuscular disorders, particularly DMD and SMA I and II, have a much higher prevalence in the first two decades of life than is generally thought. Awareness of the higher prevalence of neuromuscular disorders among the under-20s is essential to the adequate planning of medical services.

Isokinetic muscle testing (IMT) in neuromuscular diseases. Preliminary report.

Isokinetic muscle testing (IMT) allows precise and reliable measurement of the force produced by the skeletal muscle during exercise at constant velocity and accommodating resistance. This study reports on some clinical situations that illustrate the difference between manual muscle testing (MMT) and IMT in neuromuscular patients. IMT was performed by a special method (continuous passive motion plus gravity compensation) which allowed the measurement of very weak forces, such as in the four patients described in this study. It is important to note that for the same MMT grading the corresponding isokinetic force values were very different. Therefore there is an obvious correspondence between the isokinetic measurement of muscle strength and the morphological change in the muscle on the CT scan of the thigh, which did not show up on MMT. IMT could be extremely important for research into neuromuscular disorders, where the detection of even the tiniest variations in strength is relevant.

Linkage of Emery-Dreifuss muscular dystrophy to the red/green cone pigment (RGCP) genes, proximal to factor VIII.

Further DNA linkage studies on two previously described X-linked recessive Emery-Dreifuss muscular dystrophy (EMD) families are reported, which refine the localization of the gene responsible for EMD. Two recombination events indicate that the most likely localization for the EMD gene lies in the interval between DXS15/DXS52 and F8C. A maximum LOD score of 3.44 at theta = 0 is obtained for EMD vs the red and green cone pigment genes (RCP and GCP). Our data provide additional support for one of the two proposed orientations of genes and markers distal to DXS15/DXS52, with respect to the telomere. Given this favoured orientation, our data best fit a localization of EMD to within a 2 megabase (Mb) interval between DXS15/DXS52 and F8C.
