["Standards, Options and Recommendations 2001" for radiotherapy in patients with non-metastatic infiltrating breast cancer. Update. National Federation of Cancer Campaign Centers (FNCLCC)]. / Standards, Options et Recommandations 2001 pour la radiothérapie des patientes atteintes d'un cancer du sein infiltrant non métastatique, mise à jour. Fédération nationale des centres de lutte contre le cancer (FNCLCC).

CONTEXT: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of french cancer centers (FNCLCC), the 20 french cancer centers, and specialists from french public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To develop clinical practice guidelines for non metastatic breast cancer patients according to the definitions of the Standards, Options and Recommendations project. METHODS: Data were identified by searching Medline, web sites, and using the personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to 148 independent reviewers. RESULTS: This article presents the chapter radiotherapy resulting from the 2001 update of the version first published in 1996. The modified 2001 version of the standards, options and recommendations takes into account new information published. The main recommendations are: (1) Breast irradiation after conservative surgery significantly decrease the risk of local recurrence (level of evidence A) and the decrease in the risk of local recidive after chest wall irradiation is greater as the number of risk factors for local recurrence increases (level of evidence A). (2) After conservative surgery, a whole breast irradiation should be performed at a minimum dose of 50 Gy in 25 fractions (standard, level of evidence A). (3) A boost in the tumour bed should be performed in women under 50 years, even if the surgical margins are free (standard, level of evidence B). (4) Internal mammary chain irradiation is indicated for internal or central tumours in the absence of axillary lymph node involvement (expert agreement) and in the presence of lymph node involvement (standard, level of evidence B1). (5) Sub- and supra-claviculr lymph node irradiation is indicated in patients with axillary node involvement (standard, level of evidence B1).

[Intraperitoneal high dose chemotherapy as consolidation treatment for advanced ovarian carcinoma: a pilot study]. / Traitement de clôture des adénocarcinomes ovariens de stade avancé: étude pilote de chimiothérapie haute dose par voie intrapéritonéale.

Consolidation treatment of advanced ovarian carcinoma, especially the place of intraperitoneal chemotherapy, remains a controversial subject. From January 1988 to July 1995, 39 patients, median age 54 years, received intraperitoneal chemotherapy as consolidation treatment after second-look surgery. At the time of intraperitoneal chemotherapy, 30 patients had no residual disease. Intraperitoneal drug administration used a Tenckoff catheter or a lumbar needle. Treatment combined 5 fluorouracil 1 g/m2 and cisplatin 200 mg/m2, associated with a systemic sodium thiosulfate rescue as nephroprotector. A pharmacological analysis was done for 9 patients: the exposure of peritoneal cavity to cisplatin exceeded that of the plasma by 11 fold. Hematologic and nephrologic toxicity were acceptable. The median follow-up is 43 months. The disease free survival is 36,6 months, but 48,5 months if no residual disease at the time of intraperitoneal chemotherapy. Consolidation treatment by intense intraperitoneal chemotherapy is a feasible approach and might be beneficial in chemosensitive patients devoid of macroscopic remnants, but must be compared with others approaches.

[Autoimmune hemolytic anemia associated with a mature ovarian teratoma]. / Anémie hémolytique auto-immune associée à un tératome mature de l'ovaire.

UNLABELLED: The association of autoimmune hemolytic anemia and mature teratoma of the ovary is rare, particularly in childhood, but must be known and looked for since the treatment of teratoma allows to cure anemia as well. CASE REPORT: A 9 year-old girl was admitted for hemolytic anemia. The etiologic work-up revealed an autoimmune mechanism (IgG autoantibodies with complement), as well as an ovarian tumor after ultrasound sonography of the abdomen and pelvis. Surgical excision of the tumor was complete and uncomplicated. Pathological examination concluded to a mature teratoma. Anemia, as well as the signs of autoimmunity, disappeared a few weeks later and the child is doing well with several months of follow-up. CONCLUSION: This second reported pediatric case shows that an ovarian teratoma should be searched for with ultrasound sonography in any girl presenting with autoimmune hemolytic anemia, since surgical excision is sufficient to cure both anemia and the tumor.

[Results of a randomized study comparing combination of navelbine-cisplatin to combination of vindesine-cisplatin and to navelbine alone in 612 patients with inoperable non-small cell lung cancer]. / Résultats d'une étude randomisée comparant l'association Navelbine-cisplatinum à l'association vindésine-cisplatinum et à la Navelbine seule chez 612 malades porteurs d'un carcinome bronchique non à petites cellules inopérable.

The combination of vindesine and cisplatin is considered a reference regimen in advanced NSCLC which has yielded a significant improvement in the duration of survival. A phase II study of a new semi-synthetic vinca alkaloid, Navelbine, reported an unusually high 29% response rate in stage III-IV NSCLC and a phase I-II study established the feasibility of the combination of Navelbine and cisplatin. We, therefore, designed a prospective randomized trial to compare Navelbine and cisplatin (NVB-P) to vindesine and cisplatin (VDS-P) and to evaluate whether the best of these regimens affords a survival benefit compared to Navelbine alone (NVB), an outpatient regimen. Forty-five centers included 612 patients in this study: 206 in NVB-P, 200 in VDS-P and 206 in NVB. Navelbine was given at a dose of 30 mg/m2 weekly, cisplatin at 120 mg/m2 on day 1, day 29 and then every 6 weeks and vindesine at 3 mg/m2 weekly for 6 weeks and then every other week. Treatment was continued until progression or toxicity. Patients' characteristics were similar in the three groups with 59% of patients presenting with metastatic disease. An objective response rate was observed in 30% of patients in NVB-P versus 19% in VDS-P (P = .02) and 14% in NVB (P < .001). The median duration of survival was 40 weeks in NVB-P compared to 32 weeks in VDS-P and 31 weeks in NVB. The comparison of survival between the three groups demonstrated an advantage for NVB-P compared to VDS-P (P = .04) and NVB (P = .02). Neutropenia was significantly higher in the NVB-P group (P < .001) and neurotoxicity more frequent with VDS-P (P < .004). Since our results have demonstrated that NVB-P yields a longer survival duration and a higher response rate than VDS-P or NVB alone, with acceptable toxicity, this combination should be considered a reference regimen in advanced NSCLC.

Renal tolerance of cisplatin in patients more than 80 years old.

PURPOSE: Assessment of cisplatin (CDDP) tolerance in patients more than 80 years old in good general condition who may benefit from CDDP-based treatment. PATIENTS AND METHODS: Data on 35 patients older than 80 years who received one to six chemotherapy cycles (median, three cycles; total number of cycles, 98) including CDDP (60 to 100 mg/m2) were analyzed retrospectively. Before treatment, all patients had normal renal function as defined by serum creatinine (SC) levels below 132 mumol/L. Renal function was evaluated by measurement of SC and creatinine clearance (CC) before and after each course of chemotherapy. CC was calculated according to the Cockroft and Gault formula, where CC = (140 - age) x weight kg/0.814 x SC mumol/L. Renal toxicity was evaluated by the difference between prechemotherapy SC and the maximum SC level observed (delta SC) and by the difference between prechemotherapy CC and the minimal CC observed after treatment with CDDP (delta CC). The evolution of SC and CC during repeated courses of CDDP was analyzed, as were any extrarenal toxicities. RESULTS: Renal function remained stable in 19 patients (54%) with delta SC less than 18 mumol/L and 18 of 35 patients (51%) with delta CC less than 9 mL/min. A slight deterioration in renal function was observed in 13 patients (37%) with delta SC greater than 18 mumol/L and less than 60 mumol/L, and with a delta CC greater than 11 mL/min and less than 21 mL/min. In three patients (9%), delta SC was greater than 60 mumol/L (71, 73, 115 mumol/L) and delta CC was greater than 21 mL/min (25, 26, 36 mL/min). There were no cases of severe renal insufficiency, clinical ototoxicity, or neurotoxicity > or = grade 2. Treatment was terminated after one or two courses in three patients because of grade 2 or 3 hematologic toxicity and in two patients for grade 3 nausea or vomiting. CONCLUSION: CDDP at moderate doses can reasonably be administered to patients older than 80 years who may benefit from antineoplastic chemotherapy.

Inhibition of dihydropyrimidine dehydrogenase by alpha-interferon: experimental data on human tumor cell lines.

Interferons (IFNs) are very promising fluorouracil (FU) biochemical modulators. The pharmacological origin sustaining the FU-IFN synergistic interaction is not clearly understood. It was recently shown that alpha-IFN was associated with a dose-dependent decrease in FU clearance in treated patients. Dihydropyrimidine dehydrogenase (DPD) is the key regulating enzyme for FU catabolism. The effects on DPD exerted by both the IFN dose and the duration of exposure were evaluated in a panel of five human cancer cell lines. All cell lines investigated exhibited quantifiable DPD activity with inter-cell-line variability (0.118-0.318 nmol min-1 mg protein-1). A prolonged exposure to IFN (up to 5 days) was necessary to obtain a significant inhibition of DPD activity. A concentration-dependent significant decrease in DPD activity, reaching 50% of the initial activity determined for the highest IFN concentration (10(5) IU/ml), was demonstrated in all cell lines tested (5-day IFN exposure). For three cell lines, IFN potentiated the FU-induced growth inhibition in a concentration-dependent manner. Considering all cell lines and all IFN concentrations, it appears that globally, the greater the inhibition of DPD activity, the greater the FU potentiation (Spearman rank correlation on all cell lines, P = 0.011).

Dihydropyrimidine dehydrogenase activity in cancer patients.

Dihydropyrimidine dehydrogenase (DPD) is the major catabolic enzyme of pyrimidines and fluoropyrimidines. The clinical course of 2 patients with suspected DPD deficiency is described. Both patients had significantly delayed clearance of fluorouracil (5-FU), elevated plasma uracil concentrations, and subsequent lethal toxicity. The prevalence of DPD deficiency in the general population is unknown, but given the large number of cancer patients treated with 5-FU, it may be of great clinical significance. Lymphocytes have been previously shown to be a useful marker of systemic DPD activity. Because DPD activity has not been previously reported in a large population of cancer patients using 5-FU as the substrate, we determined DPD activity in lymphocytes from 66 patients with cancer. DPD activity was determined by a sensitive high performance liquid chromatography method. The mean DPD activity (S.D.) in 66 patients with head and neck cancer was 0.189 (0.071) nomol/min/mg protein with wide interpatient variability (range 0.058-0.357). DPD activity was not correlated to age (r = -0.164, P = 0.188). The mean DPD activity in men [0.192 (0.074)] was not significantly different from that in women [0.172 (0.057); t-test P = 0.418]. Likewise, there was no statistical difference in DPD activity in patients who had not received prior chemotherapy [0.195 (0.066)] to patients receiving one or more cycles of chemotherapy [0.186 (0.074); t-test P = 0.638].

Granulocytic sarcoma with meningeal leukemia but no bone marrow involvement at presentation. A report of two cases with characteristic cerebrospinal fluid cytology.

Two cases occurred of granulocytic sarcoma with cerebrospinal fluid involvement but no associated leukemia on presentation. Both cases were difficult to identify by histology and were initially misdiagnosed as malignant lymphoma. The characteristic cerebrospinal fluid cytologic picture allowed the diagnosis. These cases underscore the value of cytologic examination of tumor imprints and the use of myeloid markers in panels for immunophenotyping lymphomas.

Pharmacokinetics of mitoxantrone in cancer patients treated by high-dose chemotherapy and autologous bone marrow transplantation.

We have studied the pharmacokinetics of mitoxantrone in cancer patients. Two regimens were used: eight women (10 kinetics) received a 10 min i.v. infusion of 12 mg m-2 of mitoxantrone; seven women (seven kinetics) received high-dose mitoxantrone associated to high-dose alkylating agents and underwent autologous bone marrow transplantation (BMT). High-dose mitoxantrone was administered according to two different protocols. The drug was quantified in plasma with an HPLC assay and pharmacokinetic analysis was performed with the APIS software. Mitoxantrone pharmacokinetics were best described by an open two- (six kinetics) or an open three compartment model (11 kinetics). A large interindivual variability was observed in pharmacokinetic parameters. In the first group of patients, mean +/- s.d. values of clearance, half-life and total distribution volume were 21.41 +/- 14.59 1 h-1, 19.83 +/- 23.95 h, 165.89 +/- 134.75 1 respectively. In the high-dose group, these values were 21.68 +/- 7.30 1 h-1, 50.26 +/- 20.62 h, 413.70 +/- 194.81 1 respectively. Results showed that identification through the open 2-compartment model is certainly related to the small number of late time-points. We therefore think that mitoxantrone pharmacokinetics is generally best described by an open 3-compartment model. Clearance values showed that there was no saturation in mitoxantrone elimination, even at the highest doses. Terminal elimination half-life was probably underestimated because of the lack of late time-points in some kinetics. The half-life is long for patients receiving high-dose mitoxantrone (mean value was 50 h) and it would be hazardous to perform BMT too early after mitoxantrone infusion. Mitoxantrone metabolites were detected in the plasma of five patients receiving high-dose mitoxantrone and in one with hepatic impairment.

Role of splenectomy in incidence and severity of acute graft-versus-host disease: a multicenter study of 157 patients.

Allogeneic bone marrow transplantation is a therapeutic option for many hematological malignancies. Graft-versus-host disease (GVHD) remains one of the major complications and has a high mortality rate. The pathophysiological mechanisms involved are poorly understood and GVHD prevention regimens still give disappointing results. This study concerned 157 patients with diverse diagnoses from Bordeaux, Grenoble and Marseille who had undergone an HLA-matched transplantation without T cell depletion. Thirty-one patients (20%) had been splenectomized before transplantation. The role of splenectomy in the incidence and severity of acute GVHD was investigated using a univariate and multivariate analysis of 11 risk factors including splenectomy. Univariate analysis found three significant risk factors linked with GVHD incidence: splenectomy, age of recipient and GVHD prevention by monotherapy versus a combination of methotrexate plus cyclosporin. Multivariate analysis retained only the effects of age and GVHD prevention on GVHD incidence and showed that splenectomy was the most important factor in GVHD severity. One explanation for the role of splenectomy could be the spleen's possible function as a filter of activated T lymphocytes from the transplant. We therefore concluded that it would be preferable to abstain from splenectomizing patients before transplantation although splenectomy is still advisable in certain malignancies after transplantation.

Anti-LFA1 monoclonal antibody (25.3) for treatment of steroid-resistant grade III-IV acute graft-versus-host disease.

The in vivo efficacy of 25.3 monoclonal antibody (mAb) directed against human LFA1 molecule was assessed in ten patients with steroid-resistant grade III-IV acute graft-versus-host disease (AGVHD). These patients received non-T-cell-depleted allogeneic bone marrow transplantation for aplastic anemia in two cases and hematologic malignancies in eight cases. Five grafts were fully matched, three were one antigen-mismatched, and two were two antigen-mismatched. Despite GVHD prophylaxis with cyclosporin A and short-term methotrexate, AGVHD occurred after a median of 24 days and clearly progressed under prednisone (median 2 mg/kg), given for a median of 12 days. 25.3 mAb was given at a dosage of 0.1 mg/kg in a 4-h perfusion for five daily doses without any clinical or biological side effects. Thirty percent of the patients experienced a reduction in the overall grading with two complete responses. Partial response in at least one involved organ (mostly skin) occurred in 80% of the patients. However, seven out of the eight responding patients experienced a new episode of AGVHD. This observation, which confirms that inhibiting a functional molecule is as efficient as a cytolytic therapy, offers an alternative strategy to antithymocyte globulin (ATG) and cytotoxic mAb in controlling steroid-resistant GVHD.

Recombinant interleukin-2 (rIL-2) after autologous bone marrow transplantation (BMT): a pilot study in 19 patients.

In vivo use of rIL-2 autologous BMT may be the means of reproducing a kind of "adoptive immunotherapy" from grafted cells after allogeneic BMT. This approach may enhance the spontaneous generation of cytotoxic T-cells and NK cells which are presumably involved in this immunotherapy. Potential risks of such an approach would be to increase the usual toxicity of rIL-2 and to jeopardize the hemopoietic reconstitution. To determine the feasibility of this approach we have treated 19 poor prognosis patients with a succession of autologous BMT followed 78 +/- 12 days later by a continuous infusion of rIL-2. Eighteen million international units (IU) per m2 per day of Proleukine (CETUS, Amsterdam, The Netherlands) were administrated over 6 or 12 days. No patient died of the procedure. Clinical toxicity related to rIL-2 was not increased. Hemopoietic toxicity, significant both for platelets and granulocytes, was transient. Immune stimulation was dramatic for lymphocytes and subpopulations (CD3+ and NK cells) and for cytolytic functions (NK and LAK activity). This trial establishes the feasibility of administration of high doses of rIL-2, 2 months after autologous BMT. In this setting a 6 day period of continuous infusion of 18 million per m2 per day of Proleukine appears to be a regularly tolerable dosage conducting to a major immune activation and invites further studies to determine the clinical impact of such an approach.

Allogeneic or autologous bone marrow transplantation for acute lymphoblastic leukemia in first complete remission.

Forty-seven patients with high risk acute lymphoblastic leukemia (ALL) received an allogeneic (allo) or autologous (auto) bone marrow transplant (BMT). Patients in both groups were comparable in terms of age, initial presentation of ALL and induction chemotherapy. Allo patients were transplanted earlier (median 3 months after CR) than auto patients (median 6.5 months after CR). Auto patients received more consolidation chemotherapy before BMT. All patients received total body irradiation 2.2 Gy/day x 5 days after cyclophosphamide 60 mg/kg x 2 (18 allo and five auto) or melphalan 140 mg/m2 (seven allo and 17 auto). Prevention of graft-versus-host disease (GVHD) was by conventional immunosuppression in 17 patients and T cell depletion in eight. Seven patients (28%) developed moderate to severe acute GVHD. Auto marrow was treated in vitro in each case. Seven patients died in CR from BMT complications (five allo and two auto). The probability of relapse was 9% for patients receiving allo BMT and 52% for patients receiving auto BMT (p less than 0.01). The disease-free survival was 71% for allo BMT and 40% for auto BMT (p = NS). Early BMT is an effective form of consolidation for high risk patients with ALL in first CR. An allogeneic anti-leukemia effect was demonstrated in this study.

Liquid culture and cryopreservation of marrow cells of leukaemic patients prior to autologous bone marrow transplantation.

The feasibility of marrow cryopreservation for autologous bone marrow transplantation after 7 d in liquid culture was assessed in 10 leukaemic patients. A median of 0.17 x 10(8) nucleated cells/kg and 0.4 x 10(4) CFU-GM/kg could be collected after the complete procedure, with overall a consistent cell loss. Long-term cultures could be established from these cultured and frozen marrows, showing the persistance of precursors of haematopoietic and stromal cells. In vitro a significant decrease in the proportion of leukaemic cells could be observed in only one out of nine evaluable patients. This patient, with refractory AML, received an autologous transplant and is alive in continuous complete remission after 600 d. One patient with chronic myeloid leukaemia in acute phase underwent an autologous BMT with a marrow collected and cultured while in chronic phase and failed to engraft. These results show the feasibility of cryopreservation of cultured marrow cells for autologous bone marrow transplantation. The procedure is associated with poor cell recovery and must be improved to have a more general clinical application. This technology may have a major application with the emergence of modulators of growth and differentiation of haematopoietic cell lines.

Donor bone marrow treatment with T101 Fab fragment-ricin A-chain immunotoxin prevents graft-versus-host disease.

Thirty-eight patients with haematological malignancies were treated with bone marrow transplantation using histocompatible immunotoxin T cell-depleted marrow siblings. All patients received conventional postgraft immunosuppression (methotrexate and/or cyclosporin A). Donor bone marrow was treated ex vivo with T101 Fab fragment coupled to ricin A-chain (T101 Fab-RTA) at a concentration of 10(-8) M of A-chain in association with NH4Cl (2 x 10(-2) M) in pH adjusted (7.8) incubation medium. A median cytoreduction of 99.5% (91-99.5) was obtained. The median of follow-up was 300 days. Only three patients developed grade II acute graft-versus-host disease (GVHD) (actuarial rate of acute GVHD: 9.1%). No chronic GVHD occurred. All patients but one engrafted. Six out of the 37 patients developed a documented bone marrow rejection (actuarial rate of graft failure: 18%). Ten patients relapsed (actuarial rate of relapse: 36.9%). These findings demonstrate that treatment of donor marrow with T101 Fab-RTA in association with NH4Cl at critical pH value can achieve a high level of mature T cell depletion and greatly reduce the incidence of bone marrow rejection and relapse after T cell-depleted allogeneic bone marrow transplantation.
