Strontium-89 chloride (Metastron) for palliative treatment of bony metastases. The University of Minnesota experience.
Strontium-89 chloride (Metastron) is an FDA-approved treatment for palliation of cancer pain. We evaluated blood count changes and pain relief in 28 patients with widespread painful bony metastasis treated with strontium-89 at the University of Minnesota Hospital and Clinics. Eighteen patients had prostate cancer (all hormone-refractory cancer), seven patients had breast cancer, and three patients had lung cancer, all previously treated with either radiation, chemotherapy, or a combination of the two. ⋯ Thirty-two percent of the treated patients required additional palliative external beam radiation to their bony lesions within the study period. Our results show that Metastron for palliation for bony metastases should be used with caution because of moderate to severe bone marrow toxicity, especially in platelets, associated with its use. Careful evaluation of patients given Metastron is needed to assess accurately its full benefit.

Clinical TrialInduction chemotherapy with cisplatin, doxorubicin, and cyclophosphamide (CAP) in a combined modality approach for locally advanced and inflammatory breast cancer. Long-term results.
Thirty-one patients with locally advanced and inflammatory breast carcinoma (stage IIIA and IIIB) were treated with a combined modality approach between 1985 and 1989. All patients received as induction chemotherapy a combination of cisplatin, doxorubicin, and cyclophosphamide (CAP). Responsive patients and patients with operable stable disease underwent modified radical mastectomy followed by concurrent radiotherapy and CMF (cyclophosphamide, methotrexate, 5-fluorouracil) adjuvant chemotherapy. ⋯ At a median follow-up of 6 years, 29% (95% CI, 13.05 to 45.01) of patients were alive and 28% (95% CI, 10.4 to 45.6) were disease-free. This combined modality treatment seems feasible with quite acceptable toxicity; the CAP combination is an effective alternative to the other standard chemotherapeutic regimens. Our results, although encouraging, are still poor, and new drugs and strategies are required to improve the long-term outcome.

Syndrome of acute dyspnea related to combined mitomycin plus vinca alkaloid chemotherapy.
We report the incidence, clinical features, and course of acute dyspnea following combination chemotherapy using mitomycin and vindesine or vinblastine. The courses of 387 patients with advanced non-small cell lung cancer receiving combined mitomycin and vinca alkaloid chemotherapy were analyzed. Of these patients, 25 experienced acute respiratory distress. ⋯ The syndrome has a distinctive presentation, which can lead to chronic pulmonary insufficiency. Clinicians caring for patients receiving combined therapy with mitomycin and a vinca alkaloid should be aware of this type of acute pulmonary toxicity. Further studies are necessary to clarify its etiology.

Randomized Controlled Trial Clinical TrialOndansetron 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. ⋯ 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.

Clinical TrialThe efficacy of recombinant human granulocyte colony-stimulating factor and recombinant human granulocyte macrophage colony-stimulating factor in permitting the administration of higher doses of cyclophosphamide in a doxorubicin-cyclophosphamide combination. An NSABP pilot study in patients with metastatic or high-risk primary breast cancer. National Surgical Adjuvant Breast and Bowel Project.
Colony-stimulating factors (CSFs) shorten the duration of myelosuppression following chemotherapy and, thus, allow the administration of higher doses. This study evaluates the efficacy of granulocyte macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) in allowing administration of high-dose cyclophosphamide in combination with doxorubicin. Ninety women with metastatic, locally advanced, or high-risk (> or = 10 positive nodes) breast cancer and no prior anthracycline treatment were given doxorubicin (60 mg/m2) with progressively increased doses of cyclophosphamide (1,200 mg/m2, 1,800 mg/m2, and 2,400 mg/m2). ⋯ However, patients who received G-CSF were hospitalized less frequently than those receiving GM-CSF. With CSFs, high-dose cyclophosphamide in combination with doxorubicin can be safely administered on an outpatient basis. A shorter duration of granulocytopenia resulted from the use of G-CSF than from GM-CSF.
