Hodgkin's disease of donor origin after allogeneic bone marrow transplantation for myelogeneous chronic leukemia.

Secondary malignancies (lymphomas, leukemias, and solid tumors) occurring after bone marrow transplantation are now more frequently reported, as the patients surviving the early phase of the graft and remaining free of their original disease are more numerous. Besides early Epstein-Barr virus-associated B-cell lymphoproliferative diseases, which are the most common type and most often of donor origin, few late-occurring lymphomas have been described that might represent a distinct entity. We report here a case of Hodgkin's disease developing 8 years after allogeneic bone marrow transplantation for chronic myelogeneous leukemia. Only two Hodgkin's diseases after allogeneic bone marrow transplantation have been reported in the literature so far. The case we report is of interest because of its donor origin and its association with Epstein-Barr virus infection.

[Soft tissue sarcomas: general review]. / Sarcomes des tissus mous: revue générale.

Soft tissues sarcomas are an heterogeneous group of neoplasms. Their epidemiology is still poorly known. Great strides have been made in the genetic study over the last few years. Histologic grade, tumor size and deep location are the main independent prognostic factors in multivariate analysis using the Cox model. Overall 5-year survival is approximately 50% in most of the studies. Surgical conservative treatment associated with radiotherapy is actually preferred to radical surgery, because no survival difference is found between the two treatments. Radiation therapy modalities are discussed: preoperative, postoperative irradiation, interstitial brachytherapy. Doxorubicin, ifosfamide and DTIC are the most efficient drugs. However, response rates obtained with polychemotherapy are still less than 50%. High-dose chemotherapy is an encouraging concept. Edatrexate and Taxotere show interesting response rates in phase II clinical trials. Adjuvant chemotherapy efficiency is probably low: a meta-analysis shows a 5-year survival increase of 9%. Neoadjuvant chemotherapy allows a high rate of conservative treatment.

Chemotherapy of stage IIIB and IV non-small-cell lung cancer.

Currently, lung cancer is a leading cause of death in men with more than half million new cases diagnosed every year. Eighty percent of these tumors are non-small-cell carcinoma and 70% of these are unresectable or metastatic at the time of presentation, resulting in dramatically poor survival rates. The increasing number of drugs showing a significant activity against non-small-cell lung cancer and the widespread use of modern cisplatin based regimens offer some hope of progress and suggest that chemotherapy may have a role in treating this disease. A recent meta-analysis has confirmed the modest but significant survival benefit for patients treated with combined chemotherapy both in case of metastatic disease and in addition to radiotherapy, in locally advanced disease.

Normal serum neuron specific enolase (NSE) value after the first cycle of chemotherapy: an early predictor of complete response and survival in patients with small cell lung carcinoma.

BACKGROUND: Serum neuron specific enolase (NSE) is the most sensitive tumor marker of small cell lung carcinoma (SCLC) at diagnosis. Its prognostic value is still debated. Thus, the authors decided to assess the predictive value, in terms of complete response and survival, of serum NSE measured before and after one cycle of chemotherapy in patients with SCLC. METHODS: Sera from 135 patients with histologically proven limited (n = 63) or metastatic (n = 72) SCLC were obtained. Clinical and biologic parameters with a known or suspected prognostic relevance were reviewed. Serum NSE was measured before chemotherapy (D1-NSE) and 28 days after its initiation (D28-NSE). The prognostic value of the parameters under study was evaluated in univariate and multivariate analyses using the Cox proportional hazards model and logistic regression analysis. RESULTS: The level of serum NSE was raised in 120 patients (88%) prior to therapy. The probability of a normal D28-NSE value was not affected by the baseline D1-NSE value. Disease extension (P = 0.0005), performance status (P = 0.0001), D28-NSE (P = 0.003), and carcinoembryonic antigen (CEA) levels (P = 0.008) were found to be predictive for survival, whereas age, gender, plasma sodium, serum protides, and D1-NSE were not. Median survival and 2-year overall survival were 15.3 months and 21% (95% confidence interval [CI], 13-31%) when D28-NSE was normal and 8.1 months and 15% (95% CI, 8-27%) when it was not (P < 0.03). Only performance status (P = 0.001), disease extension (P = 0.002), and D28-NSE (P = 0.02) were found to be independent prognostic parameters for survival in the multivariate analysis. A simple prognostic index was developed using these 3 variables. Limited disease, a normal D28-NSE value, and a normal CEA value prior to therapy were the only parameters predictive for complete response in the univariate analysis, and D28-NSE (P = 0.01) and disease extension (P = 0.0001) were found to be independent variables in multivariate analysis. A complete response to therapy occurred in 62% with a normal D28-NSE value and in only 34% in the opposite case. CONCLUSIONS: Normal serum D28-NSE is a strong, independent early predictor of both complete response to therapy and survival. This simple tool may be proposed for use in the clinic and in research, in association with an assessment of disease extension and performance status, to predict the outcome of patients with SCLC.

Combination interleukin-2 and doxorubicin in advanced adult solid tumors: circumvention of doxorubicin resistance in soft-tissue sarcoma?

Based on the likelihood of antitumor interactions between cytokines and cytotoxic drugs, we designed a pilot study to evaluate feasibility, clinical, pharmacologic, and immunologic effects of concomitantly administered subcutaneous (SQ) recombinant interleukin-2 (r-IL-2) and doxorubicin (ADR) in patients with advanced solid tumors (AST). Patients received one injection of ADR alone (70 mg/m2) and 3 weeks later a combination of r-IL-2 (18 MIU/m2 days 1-5 s.q.) and ADR at the same dose either 3-4 h after the first r-IL-2 injection (arm 1) or 2 days after the last r-IL-2 injection (arm 2). The same combination was repeated every 4 weeks according to the evolution of the disease. Pharmacokinetics were assessed over 48 h after injection of ADR alone and after the first ADR-IL-2 cycle and immunologic monitoring at days 1 and 8 of the first ADR-IL-2 cycle. Tumors were measured at baseline, after ADR alone, and after each ADR-IL-2 cycle until progression. Twenty-one adult patients with various AST including 14 soft-tissue sarcomas (STS) entered the study, 11 in arm 1 and 10 in arm 2. All patients were heavily pretreated; 16 had received an anthracycline-containing chemotherapy regimen. Eleven patients were ADR refractory and 1 ADR resistant. Grade 4 neutropenia occurred in 28, 82, and 40% of patients after ADR alone, ADR-IL-2 in arm 1 and ADR-IL-2 in arm 2, respectively. Mucitis was higher in arm 1 (7 of 11 patients) compared with arm 2 (0 of 10) and ADR alone (0 of 21). SQ injections of r-IL-2 did not affect ADR pharmacokinetics. ADR injection in arm 1 prevented IL-2-induced lymphocyte rebounds in all patients but did not alter qualitatively non-major histocompatibility complex-restricted cytotoxicity. There was no response after ADR alone. Two patients, one in each arm, experienced a prolonged (8 and 5 months) objective response after ADR-IL-2. Both had ADR-refractory STS with a local relapse and metastatic metastases. Interestingly, both patients had unusually elevated TNF-alpha levels before and after the first ADR cycle. Combination ADR-IL-2, although toxic, is feasible and manageable with routine clinical support. r-IL-2 enhanced ADR hematologic and extrahematologic toxicities. The two objective responses observed in these heavily pretreated patients refractory to ADR supports the hypothesis of a modulation of ADR resistance, possibly mediated by means of a mechanism involving TNF-alpha. Elevated baseline TNF-alpha levels could be predictive of response to ADR-IL-2 and deserves further investigation.
