RESUMO

OBJECTIVES: The purpose of this prospective observational study is to evaluate the relation of the comprehensive geriatric assessment (CGA) to tolerability and survival of multi-agent chemotherapy for curative intent in elderly patients with aggressive non-Hodgkin lymphoma (NHL). MATERIALS AND METHODS: Patients who were 1) age ≥65 years, 2) newly diagnosed aggressive NHL, and 3) treated with multi-agent chemotherapy within 2 weeks from the time of diagnosis were enrolled from January 2011 to June 2014. Baseline clinical, laboratory, and CGA data being composed of Mini Nutritional Assessment-Short Form (MNA-SF), Korean version of Mini Mental Status Exam, Korean-Geriatric Depression Scale, and Groningen Frailty Index (GFI), were collected and analyzed for the relation to the outcome factors. RESULTS: Seventy patients were included; the median age was 73.5 years, 27 (38.6%) patients were Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 2 or more, and half of the patients were high or high-intermediate risk by age-adjusted international prognostic index (aaIPI). Most patients received CHOP or CHOP-like chemotherapy. Factors affecting discontinuation of chemotherapy within 12 weeks were poor MNA-SF, poor GFI, poor PS, and presence of B symptom. Among those, poor MNA-SF was independent of other variables in multivariate analysis. Poor MNA-SF, bone marrow involvement, and baseline anemia of hemoglobin<10g /dL were found to be independent factors associated with inferior overall survival whereas aaIPI factors were not. CONCLUSION: MNA-SF predicted tolerability to multi-agents chemotherapy and overall survival in elderly patients with aggressive NHL who were treated with multi-agent chemotherapy.

RESUMO

BACKGROUND: Using a parametric carcinogenesis model, we disentangle the superimposing effects of primary and relapse therapies of Hodgkin's disease on secondary neoplasias. PATIENTS AND METHODS: We analyze eight randomized trials of the German Hodgkin's lymphoma study group [5357 individuals, 67 secondary acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) and 97 secondary non-Hodgkin's lymphoma (NHL)]. Primary therapies were divided into four groups: radiotherapy alone, moderately dosed COPP/ABVD-like chemotherapies for intermediate and advanced stages and BEACOPP escalated. RESULTS: For secondary AML/MDS, the hazards after primary therapies are proportional (maximum at 3.4 years), while the hazard after relapse therapy is more peaked (maximum at 1.8 years). Intermediate and advanced stage chemotherapy resulted in a cumulative risk of 1.5%, while the risk after BEACOPP escalated is higher (4.4%, P = 0.004) and comparable with that after relapse therapy (4.5%). For secondary NHL, there are no differences in cumulative risk between the primary therapies (2.9%), while the risk after relapse therapy is increased (6.6%, P = 0.002). CONCLUSIONS: BEACOPP escalated moderately increases the risk of secondary AML/MDS but not NHL. No differences were found between other chemotherapies of advanced stages and intermediate stages. Secondary AML/MDS occurs faster after relapse treatment than after primary treatment.

RESUMO

Hypersensitivity to mosquito bite (HMB) can occur in association with chronic Epstein-Barr virus (EBV) infection and natural killer (NK) cell leukaemia/lymphoma, which was named 'Tokura-Ishihara disease'. This disease is very rare and most previous reports have been documented in Japan. We present a patient who suffered from of pustules on skin, high fever, myalgia and multiple lymph node enlargements after mosquito bite from childhood. Recently, multiple lymph nodes were palpable on his both inguinal area. Peripheral blood smear (PBS) revealed many large granular lymphocytes and the skin lesion showed a dense dermal and subcutaneous infiltrate of lymphocytes. The lymph nodes and perinodal adipose tissue were infiltrated by atypical lymphoid cells in which EBER-positive signals were identified by in situ hybridization using EBV encoded RNA-1 probe. He was diagnosed as having Tokura-Ishihara disease and receives chemotherapy now. Here, we report a case of this disease with a precise pathological description on the lymph node biopsy.

RESUMO

Chemotherapy-treated patients with advanced Hodgkin's disease (HD) differ considerably in acute hematotoxicity. Hematotoxicity may be indicative of pharmacological and metabolic heterogeneity. We hypothesized that low hematotoxicity might correlate with reduced systemic dose and thus reduced disease control. A total of 266 patients with advanced HD treated with cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastine, and dacarbazine (COPP-ABVD) were analyzed (HD6 trial of the German Hodgkin's Lymphoma Study Group). The reported WHO grade of leukocytopenia was averaged over chemotherapy cycles given and weighted with the reciprocal dose intensity of the corresponding cycle. The low and high toxicity groups were defined in retrospect as having had an averaged WHO grade of leukocytopenia 2.1, respectively. The independent impact of low hematological toxicity on freedom from treatment failure (FFTF) was assessed multivariately adjusting for the international prognostic score for advanced HD. The results were validated in two independent cohorts [181 patients treated with COPP-ABVD (HD9-trial) and 250 patients treated with COPP-ABV-ifosfamide, methotrexate, etoposide, and prednisone (IMEP) (HD6 trial)]. The 5-year FFTF rates were 68% for patients with high toxicity vs 47% for patients with low toxicity [multivariate relative risk (RR) 2.0, 95% confidence interval (CI) 1.4-3.0, p=0.0002]. Patients with low toxicity received significantly higher nominal dose ( p=0.02) and dose intensity ( p<0.0001). This finding was confirmed in both validation cohorts (multivariate RR 2.1, 95% CI 1.2-3.8, p=0.01 and RR 1.5, 95% CI 1.01-2.26, p=0.04, respectively). Patients with low hematotoxicity have significantly higher failure rates despite higher doses and dose intensity. Hematotoxicity is an independent prognostic factor for treatment outcome. This observation suggests a strategy of individualized dosing adapted to hematotoxicity.

RESUMO

BACKGROUND: The purpose of this study was to compare the efficacy of the hybrid chemotherapeutic regimen COPP/ABV/IMEP (cyclophosphamide-vincristine-procarbazine-prednisone-doxorubicin-bleomycin-vinblastine-ifosfamide-methotrexate-etoposide) (CAI) with that of the standard regimen COPP/ABVD (COPP/ABV, dacarbacine) (CA) in the treatment of advanced-stage Hodgkin's disease (HD). PATIENTS AND METHODS: Between January 1988 and January 1993, 588 eligible patients with HD in stages IIIB and IV were randomly assigned to a treatment or control group. The treatment group received four cycles of CAI over a complete cycle duration of 43 days. The control group received four cycles of CA over 57 days. Both groups then received consolidating radiotherapy. RESULTS: Five hundred and eighty-four patients were suitable for arm comparison. Patients in each group were similar in age, sex, histological subtype and clinical risk factors. Complete remission rates, overall survival and freedom from treatment failure at 7 years were similar for the two groups: 77% versus 78%, 73% versus 73% and 54% versus 56% for CAI and CA, respectively. Differences in acute chemotherapy-related toxicity were significant, however. Prognostic factor analysis confirmed the relevance of the International Prognostic Index and revealed that stage IVB, low hemoglobin, low lymphocyte count, high age and male gender were associated with a poor prognosis CONCLUSION: The rapidly alternating hybrid CAI did not give superior results when compared with the standard regimen CA in advanced-stage HD.

RESUMO

To improve the action and selectivity of new drugs on tumor cells and the use of currently available pharmaceutical technologies to develop the systems of controlled transport of well-known antitumor compounds is one of the ways of enhancing the efficiency of drug therapy for tumors. The tropicity of steroid hormones to definite organs and tissues makes it possible to use them as specific messengers of alkylating groups to target tissues and tumors. Hormone cytostatics synthesized by this principle have a double mechanism of hormonal and cytotoxic actions. The original Russian water-insoluble hormone cytostatistics testifenon, kortifen, and cytestrol acetate demonstrated local tissue irritation together with high antitumor activity. No rational dosage forms make it possible to conduct clinical trials by parenteral administration. The aim of this paper is to summarize the authors' results of designing hydrophobic antitumor hormone cytostatics. The advantages and disadvantages of different approaches to designing traditional dosage forms and to applying colloid liposomal systems for intravenous administration of water-insoluble agents are shown.

RESUMO

Few studies have been performed regarding multiple myeloma (MM) in elderly patients. We report a retrospective series of 130 unselected patients with MM aged 75 yr or more at diagnosis. Presenting features were identical to those reported in younger patients, except for a higher rate of infection. Heavy comorbidity was characteristic of unselected geriatric patients. Ninety-four patients received conventional chemotherapy. The response rate was 62%. Treatment toxicity was mild. Median survival was 22 months. Durie-Salmon (DS) clinical stages II and III MM were severe and often led to death, while significantly more patients with DS stage I MM died from unrelated causes (p<0.0001). Univariate analysis showed that age > or = 85 yr, performance status > or = 2, creatinine level > or = 120 micromol/l, beta 2 microglobulin level > 4 mg/l, C-reactive protein level > 6 mg/l, platelet count < 100 x 10(9)/l, presence of infection and lack of response to chemotherapy were adverse prognostic factors for survival. In Cox multivariate regression analysis, age > or = 85 yr (p<0.0001), performance status > or = 2 (p<0.0001) and creatinine level > or = 120 micromol/l (p<0.0001) were independent factors in predicting short survival. This study provides evidence that in patients with symptomatic MM age should not be considered as a major obstacle to active treatment. Prospective clinical trials are needed in this population of patients and should include an assessment of quality of life.

RESUMO

The purpose of this study was to investigate the effect of long-term administration of G-CSF with regard to its impact on overall survival of patients with ovarian cancer. We report the results of a non-randomized trial on 64 patients with advanced ovarian cancer treated with 6 cycles of conventional chemotherapy. Chemotherapy comprised carboplatin 400 mg/m2 and epirubicin 70 mg/m2 on day 1 of each cycle and prednimustine 100 mg/m2 on days 3 to 7, every 28 days. Thirty-three patients received CEP chemotherapy with G-CSF support whereas 31 women received CEP chemotherapy alone. The schedule of G-CSF was 5 mg/kg/day subcutanously on days 8 to 21 of each cycle. The severity of reduction in white cells and neutrophil count was significantly different in the two treatment groups (p<0.05), with more toxicity in the non- G-CSF group. G-CSF users had a non significant 0.88-fold lower risk of dying from ovarian cancer (95% CI, 0.48-1.60, p=0.678). In a survival analysis using a Cox proportional hazards model, residual tumor remained as an independent prognostic factor. The increasing amount of residual tumor resulted in a 1.767-fold higher risk (95% CI, 1.23-2.53, p=0.002) of death secondary to the underlying disease. In conclusion, this trial has failed to demonstrate any negative impact on patients' overall survival for the additional use of G-CSF with platinum-based chemotherapy; our results were consistent with the beneficial effects of G-CSF treatment on cytotoxic chemotherapy-induced myelosuppression.

RESUMO

Drug resistance of non-Hodgkin's lymphomas may involve mechanisms of the multidrug resistance phenotype including the lung resistance protein (LRP) and the multidrug resistance protein (MRP1). To determine the clinical relevance of these multidrug resistance factors in previously untreated diffuse large B-cell lymphomas (n = 48), we studied LRP and MRP1 expression in lymphoma cells and their impact on clinical outcome. LRP and MRP1 expression were immunohistochemically assessed by means of the monoclonal antibodies LRP-56 and MRPr1, respectively. LRP was positive in 23% and MRP1 in 44% of the samples. LRP expression was associated with higher tumor stage (P = 0.03), elevated serum lactate dehydrogenase levels (P = 0.01), and the International Prognostic Index (P = 0.0001). LRP-positive patients had a lower complete response rate to polychemotherapy than LRP-negative patients (18 versus 65%; P = 0.006). Patients with LRP expression had a shorter overall survival than those without LRP expression (median of 0.9 years versus median not reached; P = 0.001). MRP1 expression was independent of clinical and laboratory parameters and had no impact on the outcome of chemotherapy or survival of the patients. These data suggest that LRP expression but not MRP1 expression is an important mechanism of drug resistance associated with worse clinical outcome in previously untreated diffuse large B-cell lymphomas. Thus, the reversal of LRP-mediated drug resistance may improve clinical outcome in diffuse large B-cell lymphoma in the future.

RESUMO

In elderly patients age-specific comorbidity often reduces the possibility of administering intensive chemotherapy and of obtaining response to treatment. Therefore, chemotherapy must differ from that for non-elderly patients, while maintaining the primary goal of a complete clinical response. We treated 19 patients over the age of 70 years (median age 75 years, range 70-86) with stage II-IV high-grade non-Hodgkin's lymphoma (NHL) with a combination regimen including idarubicin plus etoposide and prednimustine (or chlorambucil+prednisone), all administered orally on an outpatient basis. The therapeutic schedule included six 5-day courses of idarubicin 20 mg/sqm on day 1 (or 10 mg/sqm on days 1 and 3 in the nine patients last treated), etoposide 60 mg/sqm/12 h days 2-5, prednimustine 60 mg/sqm days 2-5, G-CSF 300 microg/day from day+7 until PMN>1000/microl. In ten patients prednimustine was replaced by chlorambucil 10 mg/sqm, days 2-5, and prednisone 50 mg days 2-5, because of non-availability of the drug. Of the 19 patients submitted to this regimen 15 (79%) obtained a clinical response: eight reached a complete response (CR), and seven a partial response (PR). Hematologic toxicity was generally mild. Only three patients had to be hospitalised for infection. Except alopecia, non-hematologic toxicities were negligible. At a median follow-up of 16 months, five of eight patients who obtained CR relapsed (median CR duration 7 months). The actuarial median survival is 34 months (range 6-46). This study demonstrates the feasibility and efficacy of an all-oral regimen including idarubicin, plus etoposide and prednimustine (or chlorambucil+prednisone) in NHL patients aged over 70 years.

RESUMO

OBJECTIVE: The aim of the study was to evaluate the effect of additional radiotherapy after chemotherapy on the relapse-free and overall survival rates of patients with advanced ovarian cancer. METHODS: Between 1985 and 1992 64 patients with radically operated ovarian cancers (4 stage IC, 2 stage II, 54 stage III, and 4 stage IV) were enrolled in a randomized study. Radical surgery comprised total abdominal hysterectomy and bilateral salpingo-oophorectomy, omentectomy, and pelvic and paraaortic lymphadenectomy. All patients received adjuvant chemotherapy with carboplatin IV 400 mg/m2, epirubicin IV 70 mg/m2 on day 1 and prednimustine orally 100 mg/m2 on days 3 to 7 at 1-month intervals. Thirty-two patients without residual disease were randomized to whole abdominal radiation (30 Gy, administered over 4 weeks). An additional 21.6 Gy were delivered to the pelvis and 12 Gy to the paraaortic region up to the diaphragm for total doses of 51.6 and 42 Gy, respectively. Cancer-related survival was calculated with the Kaplan-Meier and Cox proportional hazards methods. RESULTS: The relapse-free and overall survival rates of patients who received adjuvant chemoradiotherapy were significantly higher than those of patients who received adjuvant chemotherapy only (68% vs 56% at 2 years and 49% vs 26% at 5 years, P = 0.013, and 87% vs 61% at 2 years and 59% vs 33% at 5 years, P = 0.029). The differences were most pronounced in patients with stage III disease (77% vs 54% at 2 years and 45% vs 19% at 5 years, P = 0. 0061, and 88% vs 58% at 2 years and 59% vs 26% at 5 years, P = 0. 012). Toxicities were acceptable. CONCLUSION: Sequential combination of platinum-based chemotherapy with open-field abdominal radiotherapy is a promising adjuvant regimen for patients with advanced ovarian cancer.

RESUMO

Elderly patients with intermediate- or high-grade non-Hodgkin's lymphoma have a worse outcome than those who are younger than 60 years. It has been shown that aggressive combination chemotherapy is poorly tolerated in older patients resulting in a subsequent decrease in dose intensity. A phase II trial was conducted with mitoxantrone, prednimustine, and vincristine (NSO) in this group of patients. NSO consists of mitoxantrone 12 mg/M2 intravenously on day one, vincristine 1.4 mg/M2 intravenously on day 1 (maximum dose of two mg), and prednimustine 100 mg/M2 orally once a day for four days. NSO was repeated every 21 days. Thirty-six patients were able to be evaluated. There were 18 males and 18 females with the median age of 71 (range 60-85). NSO was well tolerated and nonhematological toxicities were uncommon. More than 80% of the patients received 90% or greater of the intended dose. The complete response rate was 60.6% and partial response was 21.8%. At 60 months the Kaplan-Meier estimate of progression-free survival was 47.9% (standard error 8.6%) and actual survival was 40.6% (standard error 8.8%). There were no differences in outcome between those with performance status (PS) of zero or one and those with PS > 1. NSO is well tolerated by elderly patients including those with PS > 1. These results compare favorably with other combinations in elderly patients with aggressive non-Hodgkin's lymphoma.

RESUMO

PURPOSE: To compare mantle-cell lymphomas (MCLs) and follicle-center lymphomas (FCLs) for their features of clinical presentation, response to chemotherapy, and prognosis on the basis of a prospective randomized clinical trial. PATIENTS AND METHODS: Patients with MCL and FCL who entered onto the prospective randomized comparison of cyclophosphamide, vincristine, and prednisone (COP) versus prednimustine and mitoxantrone (PmM) followed by a second randomization for interferon (IFN) maintenance versus observation only. RESULTS: One hundred sixty-five of 234 patients had FCL and 45 of 234 patients had MCL. With FCL, both sexes were equally affected (men, 47%); patients with MCL were predominantly men (78%; P < .0004) and had a higher median age (64 v 53 years; P < .0001). Patients with MCL also had more widespread disease, reflected by the proportion of patients with two or greater extranodal manifestations (43% v 21%; P < .005) and nine or greater involved nodal areas (64% v 45%; nonsignificant [NS]). Response to chemotherapy was significantly lower in patients with MCL (complete remission [CR] + partial remission [PR], 69% v 88%; P < .05) and occurred at a slower pace. Patients with MCL also had a shorter event-free interval (median, 8 v 24 months; P < .0001) and overall survival (median, 28 v 77 months; P < .0001). In both subtypes, however, patients with less than two residual lymphoma manifestations in remission experienced a relatively good prognosis with an estimated 5-year survival of greater than 60% for MCL and greater than 75% for FCL. CONCLUSION: MCL and FCL differ substantially in their features of presentation, response to chemotherapy, and long-term prognosis. The extent of residual disease after completion of chemotherapy discriminates patients with different prognosis and may be used for the stratification of postremission strategies.

RESUMO

PURPOSE: We report the results of a randomized study of the European Organization for Research and Treatment of Cancer (EORTC) Lymphoma Group, which compared a chemotherapy regimen specifically devised for elderly patients, ie, etoposide, mitoxantrone, and prednimustine (VMP), versus the standard regimen of cyclophosphamide, doxorobucin, vincristine, and prednisone (CHOP) in patients older than 70 years of age with intermediate- and high-grade non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Patients older than 70 years of age with stage II, III, or IV intermediate- and high-grade NHL, with an Eastern Cooperative Oncology Group (ECOG) performance status less than 4 and acceptable cardiac, renal, and liver function were randomized to receive six courses of VMP or six courses of CHOP. Between February 1989 and June 1994, 130 patients aged 70 to 93 years (median, 75) were enrolled and 120 were assessable for response, 60 patients in each arm. RESULTS: Overall objective response rates were 50% and 77% in VMP- and CHOP-treated patients, respectively (P = .01), while complete response (CR) rates were borderline significant (27% v 45%; P = .06). At 2 years, the progression-free survival (PFS) rate was 25% with VMP versus 55% with CHOP (P = .002) and the overall survival (OS) rate was 30% with VMP versus 65% with CHOP (P = .004). Statistically significant more alopecia and neurologic and gastrointestinal toxicities were reported with CHOP. CONCLUSION: CHOP is the standard regimen for patients > or = 70 years of age with stage II to IV intermediate- and high-grade NHL.

RESUMO

We evaluated 1179 consecutive patients with low-grade B-NHL diagnosed according to criteria of the Kiel classification and presenting with initial bone marrow involvement. Therapeutic approaches were not changed during the observation period 1975-1995. CLL (n=895) and IC (n=169) were treated palliatively with chlorambucil/prednisone or prednimustine. In CBCC (n=65) and CC (n=50) remission was induced with COP or CHOP. The overall response rate was 67%, but only 35% of CBCC and 23% of CC patients achieved complete remission. Median survival was 64 months in CBCC and 28 months in CC. As the median age of our patient population was 68 years (range: 23-93) it seems doubtful whether overall prognosis can be improved by aggressive therapeutic measures. One exception might be CBCC patients who were younger (median age 56 years) and who were usually in good general condition so that they might qualify for high dosage chemotherapy and stem cell support. Whether the prognosis of IC and CLL (median survival 74 months and 107 months, respectively) can be improved by treatment with drugs such as purine analogs will depend on the long-term outcome of clinical studies.
