Contralateral axillary involvement in breast cancer recurrence: locoregional disease or metastasis?

We describe a case of right mammary homolateral recurrence with controlateral axillary invasion. The absence of occult involvement of the left breast was confirmed by MRI. A subsequent thoraco-abdomino-pelvic scan and bone scintigraphy did not reveal any metastases. Lymphoscintigraphy of the right breast, after periareolar injection, revealed lymphatic drainage from the right breast into the left contralateral axillary lymph node. Because of the changes in axillary drainage after mammary and axillary surgery observed by lymphoscintigraphy, contralateral axillary involvement could be considered as locoregional disease in the same way as homolateral lymph node involvement.

Oral vinorelbine/paclitaxel combination treatment of metastatic breast cancer: a phase I study.

PURPOSE: Intravenous (i.v.) vinorelbine (VRL) generally given on days 1 and 8 of an every three-week cycle in combination with paclitaxel (PTX) is an effective option for the treatment of metastatic breast cancer (MBC). In an effort to improve both patient and chemotherapy unit convenience, oral VRL was used at equivalent doses of i.v. VRL. PATIENTS AND METHODS: The maximal tolerated dose (MTD) was determined during the first cycle of oral VRL given on days 1 and 8 or 15 and PTX infused over 3 h on day 1 every 3 weeks, maximum of 6 cycles. The dose of oral VRL was escalated from 60 to 80 mg/m2 in 10 mg/m2 increments. Paclitaxel was administered at 110 and then 135 mg/m2. The combination regimen was given as first-line chemotherapy of MBC. Three to six patients per cohort were treated. RESULTS: Twenty-two patients were treated in the first four cohorts (oral VRL/PTX): 60/110, 70/110, 80/110 and 80/135. In cohort 4, seven patients were treated, one patient being non-evaluable for MTD, three of them presented a dose-limiting toxicity (DLT) consisting of febrile neutropenia and neutropenic infection. Therefore 80/135 was the MTD. Because 36% of oral VRL administrations on day 8 were delayed to day 15 at 80/110, two additional cohorts were tested: in cohort 5, oral VRL 60 mg/m2 on days 1 and 15 and PTX 135 mg/m2 on day 1 and in cohort 6, oral VRL 80 mg/m2 on days 1 and 15 and PTX 110 mg/m2 on day 1, every 3 weeks. In cohort 5, six out of eight patients had DLTs: omission of oral VRL on day 15 for five patients, grade 4 neutropenia>7 days for another one. Therefore the recommended dose (RD) for further clinical testing was oral VRL 80 mg/m2 on days 1 and 15 and PTX 110 mg/m2 on day 1 of an every 3-week cycle. Two of the three evaluable patients treated at the RD had a partial response. The pharmacokinetics of VRL and PTX is being analysed and will be further presented in a separate publication. CONCLUSIONS: This phase I study has determined the doses of oral VRL and PTX to be used in combination for the benefit of the patient and of the chemotherapy unit in term of nurse's workload. The recommended regimen of oral VRL 80 mg/m2 on days 1 and 15 and PTX 110 mg/m2 on day 1 given every 3 weeks will be further tested in phase II.

Non-Hodgkin's lymphomas in 137 patients aged 70 years or older: a retrospective European Organization for Research and Treatment of Cancer Lymphoma Group Study.

The results of a European Organization for Research and Treatment of Cancer (EORTC) retrospective study on non-Hodgkin's lymphoma (NHL) in elderly patients (greater than or equal to 70 years of age) seen in Europe in 1984 are reported. A precodified form was sent to 55 European institutes in order to evaluate the incidence of NHL in the elderly with regard to natural history, treatment-related toxicity, response, and survival. Thirteen institutes participated in the study. One hundred thirty-seven cases of NHL were observed in the elderly during 1984, making up 28% of the total number of NHL seen in those institutes. The median age was 77 years; 21% of the patients had favorable (low-grade) and 73% unfavorable (intermediate- and high-grade) histology, according to the Working Formulation. Stage at presentation was localized (I and II) in 60% and advanced in 37% of the patients. Most of the physicians used standard therapy regimens at reduced doses, from the beginning of the treatment. Sixty patients (44%) underwent a "conservative" treatment (one or two antineoplastic drugs or local field radiotherapy) and 77 (56%) an "aggressive" treatment (polychemotherapy regimens or extended field radiotherapy). Response was similar between the two treatment groups, but severe and lethal toxicity was significantly higher among patients treated with aggressive therapy. Prospective randomized studies are clearly needed to define the optimal treatment in elderly patients with advanced unfavorable NHL.

c-myc gene amplification in selected node-negative breast cancer patients correlates with high rate of early relapse.

In breast cancers with histologically negative axillary nodes selected for high frequency of recurrence, the amplification of c-myc, erbB-2 and int-2 genes was found to concern, respectively 25% (16/65), 31% (25/81) and 14% (10/70) of tumours. Their relation with tumour progression expressed by relapse-free survival is reported. Using univariate analyses, c-myc amplified tumours showed significant association with early (30-month period after diagnosis) (P = 0.0013) and intermediate (50-month period after diagnosis) (P = 0.0398) risks of recurrence. In contrast, only a trend towards higher relapse was observed in erbB-2 amplified breast cancers with respect to later events (occurring over the first 30-month period). Multivariate analyses indicated that c-myc amplification is an independent prognostic factor stronger than oestrogen receptor status and tumour size to define a high risk subset in node-negative patients selected for high frequency of recurrence.

Results of a phase II trial with second-line cystemustine at 60 mg/m2 in advanced soft tissue sarcoma: a trial of the EORTC Early Clinical Studies Group.

The aim of this phase II trial was to examine the efficacy of a new nitrosourea, cystemustine, in soft tissue sarcoma. Between January 1990 and March 1991, 32 pretreated patients with advanced soft tissue sarcoma were enrolled. Cystemustine was given every 2 weeks at 60 mg/m2 via a 15-min i.v. infusion. All eligible patients were considered evaluable for response and toxicity (WHO criteria). Of the 32 enrolled patients, 4 were ineligible, leaving 28 evaluable patients. All but 1 had been pretreated: 6 with adjuvant chemotherapy, 18 patients with first-line palliative chemotherapy without nitrosourea, 3 with both treatments, and 18 had received radiotherapy. Median age was 54 years (range 20-73) and median performance status was 1 (0-2). One partial response (PR, duration 12 weeks), 2 stable disease and 25 progressions were observed, giving an overall response rate of 3.57% (confidence interval: 0.1-18.4%). Toxicity was mild, and was mainly neutropenia (no grade 3 or 4), thrombocytopenia (3.57% grade 3 and grade 4) and nausea-vomiting (no grade 3 or 4). It should be noted that the treatment for the patient who obtained a PR was third line with no previous response. Cystemustine with this schedule appears to have a low clinical activity and toxicity in advanced soft tissue sarcoma.

Phase II randomized study of paclitaxel versus mitomycin in advanced breast cancer.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been shown to be an effective agent in the treatment of metastatic breast carcinoma. This multicenter randomized study compared paclitaxel 175 mg/m2 given as a 3-hour infusion every 3 weeks with mitomycin 12 mg/m2 given as an intravenous infusion every 6 weeks. Eighty-one patients have been randomized, and preliminary results of a planned analysis of the first 36 evaluable patients per arm are reported. Pretreatment characteristics were well balanced between the two groups. All patients previously have received chemotherapy for metastatic disease, and half had both adjuvant therapy and chemotherapy for metastatic disease. All but one patient previously had received anthracyclines. Of the first 81 randomized patients, 72 were evaluable for response and toxicity (four never treated, five concomitant hormonotherapy). Partial responses were seen in 17% of patients in the paclitaxel arm and 6% in the mitomycin arm (P = .14). Crossover to paclitaxel therapy following progression on mitomycin achieved an objective response rate of 24% (five of 21 patients). Responses to paclitaxel therapy lasted for a median duration of 9.1 months (range, 6.2 to 12+ months). Median time to progression was significantly longer in the paclitaxel arm (3.5 months v 1.6 months; P = .026). The quality-of-life-adjusted analysis confirmed the advantage of paclitaxel therapy, even when the delay of disease progression was adjusted for important adverse events. Adverse events, most importantly neutropenia and neuropathy, were more frequently observed in the paclitaxel arm. However, patients remained on paclitaxel therapy for many more courses than did those treated in the mitomycin arm. In conclusion, paclitaxel 175 mg/m2 given as a 3-hour intravenous infusion has been demonstrated to be an active agent in the treatment of chemotherapy-refractory advanced breast cancer, even after therapy with mitomycin has failed.

AcSDKP plasma concentrations in patients with solid tumours: comparison of two chemotherapeutic regimens.

The tetrapeptide AcSer-Asp-Lys-Pro (AcSDKP) is a physiological inhibitor of the proliferation of haematopoietic stem cells and progenitors. In Ara-C-treated mice, its plasmatic concentrations decrease while the CFU-S start cycling. Infusion of synthetic AcSDKP (Goralatide) at this time protects them from haematoxicity by blocking early cycling of CFU-S. Both in vitro and in vivo, this effect seems to be optimal in a narrow range of concentrations. Thus, a better knowledge of the kinetics of endogenous AcSDKP during cancer treatment could help to optimize the treatments with Goralatide. AcSDKP plasma levels have been measured by a specific EIA in 14 cancer patients during the two initial monthly 5 day courses of chemotherapy with 5-FU alone administered either by continuous infusions (six patients) or by 1 h daily infusions (eight patients). AcSDKP concentrations did not vary significantly during the first and the second course. Together with our previous results in AML patients treated with high doses chemotherapy (Ara-C and Anthracyclin), our present data suggest that the variations of endogenous AcSDKP in patients are dependent of the type, doses and schedule of chemotherapy.

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.

Plasma kinetic study of folinic acid and 5-methyltetrahydrofolate in healthy volunteers and cancer patients by high-performance liquid chromatography.

A reversed-phase HPLC method is described for the simultaneous determination of folinic acid, MTX, and their plasma metabolites 5-CH3-FH4 and 7-OH-MTX respectively. In addition, this technique allows the separation of FA another naturally occurring folate, and of AMT, used as internal standard. Separation of these compounds was achieved on a Waters Spherical C18 column at a flow rate of 0.8 ml.min-1. Elution was carried out with 0.1 M sodium acetate buffer (pH 5.5) as solvent A and 7.5% acetonitrile 92.5% bidistilled water as solvent B. UV detection was performed at 280 nm. This method was applied in a pharmacokinetic study of folinic acid and its plasma metabolite 5-CH3-FH4 following two different protocols: (1) i.v. bolus injection of 50 mg calcium folinate in six healthy volunteers and (2) simultaneous i.v. bolus injections of 50 mg/m2 MTX and 50 mg/m2 folinic acid in four cancer patients. Mean apparent half-life values for folinic acid and its metabolite were 7.02 +/- 1.81 h and 3.90 +/- 0.86 respectively in the first protocol, 4.80 +/- 1.48 h and 4.74 +/- 1.47 h in the second protocol. MTX and 7-OH-MTX were also quantified in the second protocol and were found not to affect the pharmacokinetics of folinic acid and 5-CH3-FH4. Since in vitro studies on metabolism of folinic acid might be of great interest in trying to assess the mechanism of action of the folates and the potential interaction of MTX and 7-OH-MTX in this mechanism via the metabolism, the chromatographic method we describe here has been adapted for the separation of all the potential intracellular monoglutamyl metabolites of folinic acid.

Etoposide and cisplatinum in resistant lymphomas.

Etoposide and cisplatinum have used separately to treat refractory lymphomas. This report describes 22 patients in whom these two agents were used in conjunction. All had been extensively treated with standard therapies previously. The combination of etoposide and cisplatinum was chosen on the basis of preclinical evidence for synergy and because these agents do not cross-react. Cisplatinum was continuously infused for 5 days at a dose of 15 mg/m2/d. As a push a 100 mg/m2/d dose of etoposide was injected on days 1 and 2 of treatment. This schedule produced good responses in 18 patients, i.e. 15 partial remissions and three complete remissions. The side effects were acceptable.

Phase-I-II study of high-dose melphalan and autologous marrow transplantation in adult patients with poor-risk non-Hodgkin's lymphomas.

Eleven adult patients with poor-risk non-Hodgkin's lymphoma were treated with high-dose melphalan (140 mg/m2) or high-dose combination chemotherapy (BCNU, Ara-C, vindesine and melphalan) followed by autologous bone marrow transplantation. Six of the eight patients evaluable for response achieved complete remission and one achieved partial remission. Response duration ranged from 1.5 to 12 months (median 2 months). Prompt hematological recovery occurred in all patients. The duration of aplasia and the extrahematological toxicity were similar in both groups. High-dose melphalan alone or associated with other drugs followed by marrow infusion appears to produce a high response rate and demonstrates the potential for salvaging patients with refractory lymphoma.

Intensive chemotherapy with high doses of BCNU, etoposide, cytosine arabinoside, and melphalan (BEAM) followed by autologous bone marrow transplantation: toxicity and antitumor activity in 26 patients with poor-risk malignancies.

Twenty-six patients (median age 33 years) with poor-risk malignancies were treated with high-dose combination chemotherapy associating BCNU-etoposide-cytosine arabinoside and melphalan (BEAM) followed by autologous bone marrow transplantation (ABMT). Twenty-one patients had malignant lymphomas, three, acute lymphoblastic leukemia (ALL), and two, malignant thymomas. Eleven patients (group 1) were not in complete remission (CR) at the time of BEAM, and fifteen patients (group 2) were in CR. Hematological recovery occurred in all patients. The duration of aplasia and the non-hematological toxicities were similar in both groups. Ten of the eleven patients (group 1) evaluable for response achieved CR and one achieved partial remission (PR). Five patients relapsed, and five are in continuous CR with a short follow-up (median 8 months). Among the fifteen patients in CR at the time of BEAM (group 2), four patients relapsed and ten patients are in unmaintained continuous CR with a median follow-up of 15 months (one patient died in CR). The disease-free survival is 53%, with 29% for patients receiving BEAM while in relapse (group 1) and 65% for patients receiving BEAM while in CR (group 2). These data indicate that BEAM followed by ABMT can produce a high antitumor response with an acceptable toxicity in patients with poor-risk malignancies.

Emergence of type 2 diabetes in an hospital based cohort of children with diabetes mellitus.

OBJECTIVES: Increasing awareness of the heterogeneity of diabetes mellitus (DM) at presentation is changing our approach to this disease. We used the 1999 American Diabetes Association (ADA) criteria to determine the distribution of DM patterns in a large pediatric cohort with the aim of documenting the emergence of type 2 diabetes mellitus. MATERIAL AND METHODS: Charts of diabetic children aged 1 to 16 years and admitted to our center between 1993 and 1998 were reviewed for data needed to achieve classification of the type of diabetes mellitus. RESULTS: Of the 382 study patients, 327 (85.6%) had autoimmune type 1 DM (clinical insulin-treated type 1 DM with immunologic and/or genetic evidence of autoimmunity) and 6 (1.6%) had idiopathic type 1 DM (clinical insulin-treated type 1 DM without evidence of autoimmunity). Four (1.0%) patients met all the criteria for type 2 DM; all were obese and three had acanthosis nigricans; in one the diagnosis was changed from type 1 to type 2 DM during follow-up. Four patients could be classified as lean patients with type 2 DM. In keeping with recent reports of a rise in the incidence of type 2 DM, 6 of these type 2 cases were diagnosed in the last year of the study. CONCLUSION: The ADA classification helps to understand the pathophysiology of pediatric DM, thus providing useful therapeutic guidance. At presentation, most cases of pediatric DM are type 1, but we show here that type 2 DM becomes now a diagnosis to consider although in children. Our study, from a one large study center is not an epidemiological one but is consistent with population studies. Systematic or targeted screening for type 2 in children should be discussed.

[Thymic seminoma. Apropos of a case diagnosed in a woman]. / Le séminome thymique. A propos d'un cas diagnostiqué chez une femme.

Primary thymic seminoma is a rare germ cell neoplasm histologically identical to testicular seminoma. About 100 cases have been reported in the world literature. The most probable pathogenic theory is abnormal migration of germinal cells from the vitelline sac to the embryonic thymus. Management involves surgery and radiotherapy. The extreme radiosensitivity of the tumor is responsible for a 5-years survival rate of 75 per cent. Thymic seminomas are usually found in young men. We report the case of a 49 year female in whom the combination of surgery and radiotherapy followed by chemotherapy provided excellent results.

[Continuous 5-day vindesine in the treatment of leukemias and lymphomas (author's transl)]. / Etude de la Vindésine en perfusion de 5 jours dans le traitement des leucémines et lymphomes.

Vindesine is a semisynthetic vinca alkaloïd. The short plasma half-life suggested that continuous infusion can improve the therapeutic results by maintaining a constant plasma level. Twenty one patients (acute lymphoblastic leukemia = 5 cases; blastic crisis of chronic myelocytic leukemia = 6 cases; lymphomas 10 cases) received 5-day Vindesine infusion (0,7 mg/m2/d). All these patients had previously several treatments and were resistant to usual chemotherapies including other vinca alkaloids (76% of cases). Eighteen patients were evaluable for response: 13 (72%) had partial responses or minor regressions. Toxicity was not important. Continuous 5-day infusion of Vindesine might be used widely in patients with blood diseases.

Inflammatory carcinoma of the breast.

Inflammatory breast carcinoma has to be defined by accurate clinical and pathological criteria. The prognosis is very poor and improvements made by chemotherapy are limited to the increase in the disease-free period and overall survival for a few months.

[Pleurisy in blood diseases: value of thoracoscopic poudrage]. / Pleurésies des hémopathies: intérêt du talcage thoracoscopique.

Twenty-five pleural effusions which occurred in 21 lymphoma patients (mean age: 50.6 +/- 4.6 years) were treated by pleural poudrage during thoracoscopy. The effusion was either serofibrinous (32%) or haemorrhagic (41%) or chylous (27%). The mean amount of fluid removed before poudrage was 5.2 +/- 0.6 litres. Thoracoscopy confirmed direct pleural invasion in 95.5% of the cases. Permanent pleural symphysis was obtained in all but 2 patients: one who required one single puncture withdrawing 400 cc, the other with mesothelioma on cured Hodgkin's disease, which was a failure. The mean duration of drainage was 4.8 +/- 0.2 days. The results obtained were identical with those reported with pleurisy in solid tumours.

[Resection of iliac vessels and adnexial cancer: report of 2 cases]. / Résection vasculaire et cancers annexiels : à propos de 2 cas.

Aim of no residual macroscopic disease has to be the objective of the gynecologist oncologist surgeon. It can require extensive surgical procedures in all the abdomen area. We report 2 rare cases of cytoreductive surgery with iliac vessels resection and use of vascular prosthesis. We discuss the opportunity of this surgery with high morbidity.
