Primary chemotherapy to avoid mastectomy in tumors with diameters of three centimeters or more.

In 165 women with breast cancer who were candidates for mastectomy because the largest diameter of the tumor was 3 cm or more, we administered primary chemotherapy in the attempt to substitute conservative for mutilating surgery. We then systematically quantitated tumor reduction by clinical, radiologic, and histopathologic evaluations. Five consecutive groups of 33 patients received cyclophosphamide, methotrexate, and fluorouracil (CMF); fluorouracil, doxorubicin (Adriamycin), and cyclophosphamide (FAC); or fluorouracil, epirubicin, and cyclophosphamide (FEC). The regimens for the five groups were as follows: group 1, three cycles of CMF; group 2, four cycles of CMF; group 3, three cycles of FAC; group 4, four cycles of FAC; and group 5, three cycles of FEC. In response to primary chemotherapy, 157 of the 161 assessable patients showed measurable tumor shrinkage; progressive disease was documented in four. Tumor shrinkage to less than 3 cm was documented in 127 (81%) of the 157 women subjected to surgery, thus allowing a breast-saving procedure, rather than modified radical mastectomy, in these 127 women. Histopathologic complete remission was documented in seven patients. Tumor response was unrelated to age, menopausal status, DNA content (ploidy), [3H]thymidine-labeling index, drug combination used, or number of treatment cycles in excess of three. The degree of response was inversely proportional to the initial tumor size, and the frequency of response was greater in receptor-negative tumors. Severe vomiting and hair loss were less frequent with CMF than with anthracycline-containing regimens, and the frequency of severe leukopenia and thrombocytopenia was minimal. Our results challenge the classical indication for primary mastectomy by showing that use of full-dose primary chemotherapy, sequentially combined with conservative surgery and radiation, can offer an effective and safe alternative to women concerned about the preservation of body integrity.

Anesthesia for diagnostic and therapeutic procedures in pediatric outpatients.

Appropriate sedation of pediatric oncology patients during painful diagnostic and therapeutic procedures is a recognized problem. At the Memorial Sloan-Kettering Cancer Center the pediatric oncologists and anesthesiologists have developed a cooperative program that has provided safe and effective sedation of outpatients. The experience with 100 consecutive outpatients is reported. Patients ranged from 3 months to 17 years of age. Procedures included lumbar puncture and/or intrathecal chemotherapy, multiple bone marrow aspirations, bone marrow biopsies, and removal of indwelling central vein catheters. Monitoring of patients during the procedures as well as various pharmacologic techniques to provide adequate working conditions are described.

The use of home spirometry in detecting acute lung rejection and infection following heart-lung transplantation.

The value of home spirometry in detecting acute lung rejection and opportunistic infections was studied in 15 heart-lung transplant recipients over a six-month period. The patients measured their FEV1 and FVC twice daily at home using a portable turbine spirometer. The records were then reviewed in relation to the results of transbronchial lung biopsy carried out during occurrences of respiratory symptoms and during routine posttransplant assessment. FEV1 and FVC fell by a mean (+/- SD) of 10.4 +/- 6.9 percent and 9.3 +/- 7.9 percent, respectively, during 20 episodes of lung rejection. The corresponding figures during opportunistic infections were 12.8 +/- 10.1 percent and 12.5 +/- 14.3 percent. No such change was observed during routine normal biopsies. Regular home spirometry offered early detection of these complications allowing early transbronchial lung biopsy as well as assessing efficacy of their therapy. Above all, measurements can be made daily, which is unique in the assessment of solid organ transplants.

New perspectives in medical management of hyperprolactinemia.

We performed 113 new treatments in 98 patients (pts) (69 females and 27 males), 41 with macroprolactinoma, 26 with microprolactinoma, 5 with empty sella and 26 with idiopathic hyperprolactinemia. Parlodel LA was administered in 31/113, Parlodel LAR in 51/113, Parlodel SRO in 24/113 and Cabergoline in 8/113. In each pt the clinical effect, PRL plasma level CT-scan and visual field examination were monitored. PRL plasma levels normalized in 84/98 pts. In 13/41 macroadenoma pts a complete disappearance of the adenomatous mass was observed at CT-scan after 0.5-3 years' oral bromocriptine or Parlodel LAR therapy. The clinical features normalized in most of the pts. In conclusion, the new long acting dopamine agonists may represent the future of the management of hyperprolactinemic states because of their effectiveness, tolerability and good compliance.

Mitomycin C and vinblastine in advanced refractory breast cancer.

A combination of mitomycin C and vinblastine was administered as salvage treatment in 44 patients with heavily pretreated refractory breast cancer. Response rate was 23% (10 of 44) including one complete response of lung metastases. The highest response rate was seen in intrathoracic localizations (45%). Median duration of response was 6.5 months (range, 3+-17+). Treatment was generally well tolerated, and only 25% of patients developed nausea and vomiting. Neurologic toxicity was represented by paresthesia (8 patients) and constipation (one patient). Mild leukopenia was observed in 30 of 172 treatment cycles, but it exceeded grade 2 in only 5 patients. Considering the good compliance of this regimen and the poor prognosis of patients with advanced refractory disease, the combination of mitomycin C plus vinblastine appears to be useful as salvage treatment for metastatic breast cancer.

Cytogenetic analysis of different cellular populations in chronic myelomonocytic leukemia.

Karyotypes of different cellular populations made after separation of bone marrow cells on a gradient of Percoll were evaluated in seven patients affected by chronic myelomonocytic leukemia diagnosed according to FAB criteria. Megakaryocytes, monocytic cells, and granulocytic and erythroid precursors were preferentially collected after centrifugation between density layers of 1045-1050 mg/ml, 1050-1060 mg/ml, and 1065-1070 mg/ml, respectively. The enriched cell fractions were cultured separately and submitted to cytogenetic investigation after short-term culture. Some chromosome aberrations (5q-,+8) were observed in all cellular fractions in three patients, thus providing cytogenetic evidence of the involvement of a common progenitor stem cell in this myelodysplastic disorder. On the other hand, chromosome abnormalities such as del(3)(q21) and del(11)(q23) appeared to be confined to the megakaryocytic and the monocytic fractions, respectively, in two patients. It is conceivable that lineage-restricted aberrations may develop as a consequence of a multistep clonal evolution and may show a close relationship with the hemopoietic differentiative processes.

Phase II study with ifosfamide in advanced malignant melanoma.

Ifosfamide was tested in a phase II study in 12 evaluable patients with advanced malignant melanoma. The drug was administered at the dose of 3 g/m2 on days one and two every 3-weeks. Seven patients were not previously treated and 5 received only minimal prior chemotherapy. Visceral involvement was present in 9 patients, and the remaining 3 had only soft tissue lesions. No patient showed objective tumor response. Mild vomiting was observed in 75% of patients; alopecia occurred in all of them. No other major side effects were observed, in particular, myelotoxicity and urotoxicity. Lack of response advised us to discontinue patient accrual. Our data do not support a therapeutic role of ifosfamide at the given dose schedule in the treatment of metastatic malignant melanoma.

Cyclophosphamide, adriamycin, and cis-platinum (CAP) in metastatic and locally advanced breast cancer.

A combination of cyclophosphamide, adriamycin, and cis-platinum (CAP) was tested in 20 previously untreated patients with locally advanced or metastatic breast cancer with the aim of assessing the ability of this platinum-containing regimen to induce a high complete remission rate. The drug regimen was given on a 3/week schedule at the following doses: cyclophosphamide 200 mg/m2 i.v. on days 1, 2, 3; adriamycin 40 mg/m2 i.v. or day 1 and cis-platinum 20 mg/m2 i.v. plus hydration on days 1, 2, 3. In the absence of progression, six cycles of CAP were planned and response was evaluated at that time. Thirteen of 20 patients achieved partial remission (65%) but only one obtained complete remission (5%). Overall median duration of response was 9 months (range 4-20 + months). Tumor response was mainly documented in soft tissues (primary tumor: 14 of 16; other sites: 19 of 20). Grade II leukopenia was documented in 60% of patients. All patients experienced moderate to severe gastrointestinal toxicity and alopecia was universal. No renal toxicity was observed. Although CAP regimen at the given dose schedule induced a high overall response rate (70%), the complete remission rate in this limited number of patients was lower than expected. These results do not appear superior to those achieved with conventional drug regimens.

Clinical evaluation of the cardiac toxicity of 4'-deoxy-doxorubicin.

4'-deoxy-doxorubicin, a new doxorubicin analog, was tested in 65 phase II patients with advanced malignancies. Cardiac toxicity evaluation was performed by means of electrocardiography (ECG), left ventricular systolic time intervals, echocardiography and radionuclide left ventricular ejection fraction. ECG abnormalities were observed in a lower percentage of patients (23%) compared to that described for doxorubicin and other anthracycline analogs such as 4'-epi-doxorubicin and 4-demethoxy-daunorubicin. Other functional parameters serially measured to evaluate chronic cardiotoxicity in 23 patients, who received more than 200 mg/m2 were not significantly different from mean pretreatment values. No patient developed congestive heart failure but some of them exhibited a fall of left ventricular function parameters more than 15% from pretreatment values. These data suggest that this new analogue is probably less cardiotoxic than the parent compound doxorubicin but not completely devoid of cardiotoxicity.

A phase I trial of continuous infusion cisplatin.

Treatment with continuous infusions of cisplatin results in increased filterable drug exposures as measured by the area under the curve (AUC) of nonprotein-bound plasma platinum levels. To determine the dose-limiting toxicity and optimal method of administration, 24 patients were treated with continuous infusions of cisplatin at a dose rate of 25 mg/M2/day in a limited Phase I trial. A total of 47 courses were given. Nine patients received 13 courses of 4 days duration, 19 received 29 courses of 5 days duration, and five received courses of 6 or 7 days duration. Dose-limiting toxicity was found to be leukopenia: 42% of patients receiving the 5-day treatment developed a nadir count of less than 3000 cells/mm3. Nausea and vomiting were easily controlled. Minimal nephrotoxicity occurred in five patients and was associated with daily volume expansion with 2 l of 0.9% NaCl solution in four patients. All other patients were given 3 l of daily volume expansion during treatment. Responses were seen in 6 of 22 evaluable patients (27%). It is concluded that continuous infusion cisplatin at a dose rate of 25 mg/M2/day can be given safely for 5 days as a single agent if concomitant volume expansion with at least 3 l of 0.9% NaCl solution is given daily. Phase III comparative trials with a conventional bolus and newer high-dose regimens for response and toxicity are indicated.

Four-drug sequential regimen in advanced breast cancer.

The results of two empirically designed and potentially non-cross-resistant combinations administered sequentially in advanced breast cancer with the intent of achieving a high rate of durable complete remissions were analyzed. The two drug combinations consisted of cyclophosphamide plus Adriamycin and high-dose methotrexate plus cisplatin given for a total of three cycles; twenty evaluable patients, not previously treated with chemotherapy, were entered into the study. Ten patients were allocated to receive cyclophosphamide and Adriamycin first followed by high-dose methotrexate and cisplatin, while the remaining patients received the opposite sequence. The overall response rate for the entire group was 85% (17 of 20). However, only three of 20 (15%) patients achieved complete remission. One additional complete response was observed when treatment was prolonged for an additional complete cycle. The overall median duration of response was 13 months (range, 5-20+ months). Responses were similarly distributed among different sites of lesions. Myelosuppression and gastrointestinal toxicity were mild and transient. Reversible acute renal failure was observed after methotrexate administration in three cases. Present results indicate that overall this sequential treatment appears effective in patients with advanced breast cancer. However, the lack of an increased complete remission rate over conventional regimens coupled with a potential risk of renal toxicity prevents further studies with this multiple drug combination.

Chromosome abnormalities in myelofibrosis.

Cytogenetic analysis was performed on megakaryocyte-enriched cell fractions obtained by separation on discontinuous Percoll gradients from blood, bone marrow, and ascitic fluid of 12 patients with myelofibrosis with myeloid metaplasia (MMM). The most common abnormalities appeared to involve chromosomes 1, 3, 7, 8, 11, 13, 21 and 22. Although no specific chromosome rearrangements were observed in megakaryocytic fractions from different tissues of the patients with MMM, the presence in one case of a 3q-abnormality restricted to polyploid metaphases only, and of a 3q paracentric inversion in another patient, seems to confirm a close relationship between the involvement of chromosome 3 and dysplastic thrombopoiesis.
