Extramedullary plasmacytoma: clinical behaviour and response to treatment.

The clinical features and response to treatment of 35 patients (pts) with extramedullary plasmacytoma (EMP) were retrospectively analysed. The median age at diagnosis was 49 years (28-72). Twenty-two pts (63%) had stage I disease (localized to the primary site) 12 of whom (34%) had stage I-E (locally extended). Three pts (9%) had stage II (regional lymph nodes involved) and 10 (29%) stage III (disseminated disease). In locoregional disease (stages I, I-E, II) complete local control was achieved in 22 of 25 pts (88%), while in diffuse disease (stage III) complete remission (CR) was obtained in 5 of 10 pts (50%) (p = 0.05). In 9 of 18 pts treated with surgery, local control was achieved, and in 8 of the 9 patients with incomplete resection local control was obtained with additional radiation and/or chemotherapy. In 8 (66%) of the 12 pts treated with radiation complete local control was achieved. In 11 (58%) of 19 pts evaluable for initial chemotherapy CR was obtained. Three of these pts were treated with chemotherapy only and were alive and disease-free after a minimum follow-up of 8 years. The median time to relapse in local disease was 48 months versus 13 in disseminated disease. For pts with local disease the median survival time was 114 months and for disseminated disease 16 months (p = 0.0000). We conclude that in stage I chemotherapy is curative per se. In local stages (I, I-E and II) adjuvant chemotherapy should be considered, while in stage III only palliative therapy is feasible.

Second and third responses to the same induction regimen in relapsing patients with multiple myeloma.

From September 1975 to December 1986, 115 consecutive previously untreated patients with multiple myeloma (MM) were treated with combination chemotherapy consisting of BCNU, cyclophosphamide, melphalan, vincristine, and prednisone (M-2). No patients were excluded or lost during follow-up. Forty-three percent of the patients were Stage I plus II, and 57% were Stage III. Thirty-eight patients (33%) had blood urea nitrogen greater than or equal to 40 mg/dl (substage B). Reaching an objective response treatment was stopped, generally after 1 year, and restarted at relapse. After induction therapy, 94 patients (82%) responded and had a median duration of response (MDR) of 22 months. After first relapse, 26 of 38 patients (69%) responded again to the same regimen and had an MDR of 11 months. This response rate and MDR are significantly lower than the ones achieved in induction chemotherapy. After second relapse, 7 of 16 patients (44%) again responded with an MDR of 3.5 months. The median survival time (MST) was 50.5 months for all patients. The most relevant side effect was leukopenia. No case of secondary leukemia was noticed. The authors conclude that patients with MM can be treated safely without maintenance therapy after reaching remission because a high response rate can be obtained in first and even second relapse. The planned treatment pause at remission does not adversely affect the survival time. Secondary leukemia is infrequent after this policy. Quality of life improves during the treatment pause.

Successful cardiopulmonary resuscitation using high doses of epinephrine.

Cardiac arrest usually carries a bleak prognosis when occurring in patients who have undergone open heart surgery. We report two cases where cardiac arrest was not responsive to routine therapies. Doses of epinephrine 5-10 times higher than recommended were able to provide a resolution, and the patients were discharged in a normal neurological state.

Cisplatin, etoposide, and ifosfamide in non-small cell lung carcinoma. A phase II randomized study with cisplatin and etoposide as the control arm.

A Phase II randomized study testing the combination of cisplatin, etoposide, and ifosfamide (PEI) in non-small cell lung cancer (NSCLC) was performed. The standard combination of cisplatin and etoposide (PE) was used as the control arm. Since January 1987, 78 patients were enrolled and then stratified for previous treatments and performance status (PS). The response rate (RR) of PEI was 26% (95% confidence limits [95 CL], 12% to 40%), with one complete response (CR). The RR of PE was 26% (95 CL, 13% to 39%), with no CR. The median response duration was 5 months (range, 2 to 13 months) for PEI and 4 months (range, 2 to 6 months) for PE. The median survival time was 6 months (range, 1 to 22+ months) for PEI and 7 months (range, 1 to 21+ months) for PE. Leukopenia at recycling was similar in both arms (25% for PEI and 29% of PE). The median leukocyte nadir was 2100/microliters (range, 430 to 4870/microliters) for PEI patients and 3150/microliters (range, 500 to 5000/microliters) for PE patients. Three patients had a drug-related death secondary to infections. This Phase II randomized study suggested that the combination of cisplatin plus etoposide and ifosfamide produces results similar to those obtainable with cisplatin and etoposide.

Response and toxicity of cisplatin and 120-h 5-fluorouracil infusion in pretreated and untreated patients with advanced epidermoid cancer of the head and neck.

Eighty-two patients with advanced or recurrent squamous cell carcinoma of the head and neck were treated with bolus cisplatin and 120-h infusion of 5-fluorouracil. Among 49 pretreated patients, there were 9 complete and 12 partial responses, for an overall response rate of 43% and a median estimated survival of 8 months. Hematologic toxicity in this group was relevant, with 4 early deaths and 30% of cases with moderate to severe leukopenia; mucosal and renal toxicities were also important. Among 33 patients with no prior therapy, there were 8 complete and 17 partial responses, for an overall response rate of 76%. Fifteen of the 25 responding patients received subsequent locoregional treatment. The median estimated survival in this group was 29 months. Hematologic, mucosal, and renal toxicities were only mild to moderate. Episodes of possible 5-fluorouracil-related cardiotoxicity were recorded in both pretreated and untreated patients. Twelve of 41 partial responses observed after the second cycle of therapy were converted to complete responses with a third (8 cases) and also a fourth (4 cases) course. This study confirmed that cisplatin plus 5-fluorouracil is a first-choice combination in previously untreated patients. Definitive evidence that chemotherapy can favorable influence survival awaits confirmation by randomized trials, using a control arm with conventional locoregional treatment. In previously treated patients with recurrent disease, less intensive regimens not requiring hospitalization seem more useful for the quality of life.

Chemotherapy of invasive thymoma.

Thirty-two patients with stage III or IV invasive thymoma (14 women and 18 men; median age, 40 years) were treated at the Padua Medical Oncology Department from 1977 to 1988. All patients received the following chemotherapy in 4-day courses: 50 mg/m2 of cisplatin intravenously (IV) and 40 mg/m2 of doxorubicin IV on day 1; 0.6 mg/m2 of vincristine IV on day 3; and 700 mg/m2 of cyclophosphamide IV on day 4 (ADOC). The courses were repeated every 3 weeks, and toxic effects were tolerable. The radiologically defined overall clinical response rate (complete plus partial response) was 91% with 47% clinical complete remissions; median time to progression was 11 months (range, 0 to 96) and the median estimated (Kaplan-Meier) progression-free interval was 22 months. Five of the 15 clinical complete remissions were pathologically confirmed at thoracotomy. We believe the ADOC regimen qualifies for adjuvant and preoperative treatment of invasive thymoma due to the high complete response and overall response rates.

Intrapericardial instillation of platin in malignant pericardial effusion.

Six patients (four men and two women) affected by malignant pericardial effusion, as confirmed by cytologic examination, were treated with direct intrapericardial administration of cisplatin. Median age was 36.8 years (range, 18 to 56 years). After insertion of a radiopaque polyurethane catheter (Centracath Vygon, Laboratoires Pharmaceutiques, Vygon-Ecouen, France), fluid was drained and cisplatin (10 mg in 20 ml of normal saline) was instilled over 5 minutes on 5 consecutive days (total cisplatin dose, 50 mg). At the end of the course, the catheter was withdrawn. Courses were repeated every 2 or 3 weeks in case of fluid reaccumulation. The median number of courses was two, with a range of one to three courses. Three patients achieved complete response and all three died of primary disease progression without evidence of pericardial recurrence or stricture. Mild nausea occurred in all patients. No hematologic and renal toxicity and local or infectious complications were observed.

Recombinant alpha-interferon and vinblastine in metastatic renal cell carcinoma: efficacy of low doses.

Twenty-six patients with metastatic renal cell carcinoma (RCC) were treated in a phase I-II trial with recombinant interferon alpha-2b (alpha-IFN) and vinblastine (VBL) in combination. Patients received IFN at a starting dose of 3 x 10(6) IU/m2 subcutaneously three times a week and VBL 0.1 mg/kg intravenously every 3 weeks, with dose modification for toxicity. All patients were evaluable for toxicity; 18 patients were evaluable for efficacy. An objective response rate of 44% was observed (eight of 18 patients, with one complete response and seven partial responses). The median duration of response was 5 months. The actuarial survival of responding patients was significantly longer than that of nonresponding patients. In general, the toxicity was tolerable; the subjective toxicity and fever were similar to that reported for the same doses of IFN alone. Only a mild neurotoxicity, usually mixed polyneuropathy, occurred with increased frequency. Alpha-IFN and VBL administered at low doses in combination demonstrated the highest response rate so far reported in RCC without significant toxicity.

Cisplatin plus vindesine versus cisplatin plus VP16 versus doxorubicin plus cytoxan in non-small-cell carcinoma of the lung. A randomized study.

From March 1981 to January 1984, 116 patients with advanced non-small-cell carcinoma of the lung (NSCCL) were randomly assigned to 3 combinations as follows: CDDP + DVA, CDDP + VP16 and DXR + CTX. 94 patients were evaluable for response, 106 for toxicity and survival. Of 31 patients, 15 (48%; 3 CRs and 12 PRs) responded to CDDP + DVA; of 33 patients, 12 (36%, 2 CRs and 10 PRs) responded to CDDP + VP16; of 30 patients, 3 (10%) obtained a PR with DXR + CTX (CDDP + DVA vs DXR + CTX, P less than 0.005; CDDP + VP16 vs DXR + CTX, P less than 0.05; CDDP + DVA vs CDDP + VP16, P = NS). The median duration of response was 22 weeks in the CDDP-DVA group, 17 weeks in the CDDP-VP16 group, and 16 weeks in the DXR + CTX group. No significant difference in survival was observed among the 3 groups (median: 43, 47, 41 weeks, respectively). Hematologic and neurologic toxicities were significantly higher in the DVA-containing regimen. Despite the lack of improvement of overall survival with the CDDP-containing combinations over the DXR + CTX control group, the good response rate makes them suitable to be used in combined therapeutic strategies.

Peptichemio in pretreated patients with plasmacell neoplasms.

Twenty-one patients with alkylator-resistant plasmacell neoplasms were treated with Peptichemio (PTC) at a dose of 40 mg/m2 for 3 days every 3 weeks or, in the case of persistent leukopenia and/or thrombocytopenia, at the single dose of 70 mg/m2 every 2-3 weeks according to haematological recovery. Seventeen patients, 10 with multiple myeloma and seven with extramedullary plasmacytoma (EMP), were fully evaluable. Six of 17 patients (35%) responded: three of seven EMP patients had a complete remission and 3 of 10 multiple myeloma patients had an objective response greater than 50%. The median duration of response was 8.5 months. An EMP patient obtained a complete response lasting for 16 months. The most frequent toxic effect were phlebosclerosis, occurring in all the patients, and myelosuppression, which was severe in only one case. PTC appears to be an active drug in patients with plasmacell neoplasms even if resistant to alkylating agents.

Phase II study of cisplatin, 5-FU, and allopurinol in advanced esophageal cancer.

Forty patients with advanced squamous cell carcinoma of the esophagus were treated with a combination of cisplatin, 5-FU (by continuous 5-day infusion), and allopurinol; 37 are evaluable for response. Thirteen remissions (35%) were obtained, including three complete and ten partial, with a median duration of 9 months. After chemotherapy, seven responding patients underwent a surgical procedure, which was radical in four. The most frequent side effects were nausea and vomiting. This regimen is effective and can be included in a multimodality approach.
