RESUMO

BACKGROUND: In the phase III PAOLA-1 study, the addition of maintenance olaparib to bevacizumab in patients with newly diagnosed high-grade ovarian cancer (HGOC) resulted in prolonged progression-free survival (PFS), particularly for homologous recombination deficiency-positive tumors, including those with a BRCA mutation (BRCAm). The magnitude of benefit from olaparib and bevacizumab according to the location of mutation in BRCA1/BRCA2 remains to be explored. PATIENTS AND METHODS: Patients with advanced-stage HGOC responding after platinum-based chemotherapy + bevacizumab received maintenance therapy bevacizumab (15 mg/kg q3w for 15 months) + either olaparib (300 mg b.i.d. for 24 months) or placebo. PFS was analyzed in the subgroup of patients with BRCA1m/BRCA2m according to mutation location in the functional domains of BRCA1 [Really Interesting Gene (RING), DNA-binding domain (DBD), or C-terminal domain of BRCA1 (BRCT)] and BRCA2 [RAD51-binding domain (RAD51-BD); DBD]. RESULTS: From 806 randomized patients, 159 harbored BRCA1m (19.7%) and 74 BRCA2m (9.2%). BRCA1m in RING, DBD, and BRCT domains was detected in 18, 40, and 33 patients, and BRCA2m in RAD51-BD and DBD in 36 and 13 patients, respectively. After a median follow-up of 25.5 months, benefit from maintenance olaparib + bevacizumab was observed irrespective of location of BRCAm. The benefit was particularly high for those with BRCA1m located in the DBD, with 24-month PFS estimated to be 89% and 15% [olaparib + bevacizumab versus placebo + bevacizumab hazard ratio = 0.08 (95% confidence interval 0.02-0.28); interaction P = 0.03]. In BRCA2m patients, 24-month PFS rates for those with mutations located in the DBD were 90% and 100% (olaparib + bevacizumab versus placebo + bevacizumab), respectively. CONCLUSIONS: Advanced-stage BRCA-mutated HGOC patients reported PFS benefit from maintenance olaparib and bevacizumab regardless of mutation location. The benefit is particularly high for patients with mutations located in the DBD of BRCA1. Mutations located in the DBD of BRCA2 are also associated with excellent outcome.

RESUMO

INTRODUCTION: Meningococcemia without meningitis is an often under recognized clinical form of invasive Neisseria meningitidis infection. CASE REPORTS: We report two unusual cases of invasive meningococcal disease who presented with meningococcemia without distinct signs of meningitis or severe sepsis manifestation. In both cases, confirmation of the diagnosis is provided by meningococcal PCR performed on blood or skin lesion biopsy. CONCLUSION: Clinical recognition of this entity is crucial for early antibiotic treatment and to avoid delayed diagnosis and potentially dangerous complications.

RESUMO

Metaphase cytogenetics (MC) has a major role in the risk stratification of patients with myelodysplastic syndromes (MDSs) and can affect the choice of therapies. Azacitidine (AZA) has changed the outcome of patients with MDS or acute myeloid leukemia (AML) unfit for intensive chemotherapy. Identification of patients without the benefit of AZA would allow AZA combination or other drugs in first-line treatments. New whole-genome scanning technologies such as single nucleotide polymorphism microarray (SNP-A)-based molecular karyotyping (MK) improve the risk stratification in MDS and AML. Maintenance of genomic integrity is less than three megabases (Mbs) total disruption of the genome correlated with better overall survival (OS) in patients with lower-risk MDS. In this SNP-A study, we aimed at defining a cutoff value for total genomic copy number (CN) alterations (TGA) influencing the median OS in a cohort of 51 higher-risk MDS/AML patients treated with AZA. We observed that the relative risk of worse OS increased >100 Mb of TGA, as detected by SNP-A-based MK (8 and 15 months respectively, P=0.02). Our data suggest that precise measurement of TGA could provide predictive information in poor and very poor revised International Prognostic Scoring system (IPSS-R) patients treated with AZA.

RESUMO

RATIONALE: Docetaxel has proven its efficacy in the management of hormone-refractory prostate cancer (HRPC). Schedules of docetaxel administration differ. This prospective phase II study was designed to reevaluate the activity and toxicity of docetaxel administered weekly at an optimal dose to a large cohort of HRPC patients. PATIENTS AND METHODS: Sixty-four patients were treated with docetaxel 40 mg/m(2) i.v., administered weekly for 6 consecutive weeks followed by a 2-week recovery period. Three treatment cycles were planned in the absence of progression or toxicity. The principal end point was the biochemical response based on the prostate-specific antigen (PSA) level (a decline of more than 50% for at least 4 weeks). Secondary end points were objective response to measurable disease, survival and toxicity. RESULTS: Toxicity was assessed in 64 patients. Toxicity was acceptable, with no toxicity-related deaths. Twenty-one percent of the patients developed grade 3-4 hematological toxicity. Sixty-four patients were evaluable for the PSA response. Forty-one patients (64%) achieved a decrease in PSA of >50%, 13 of whom had a PSA <4 ng/ml. Two out of 12 patients with measurable disease exhibited an objective response. With respect to PSA, the median progression-free survival was 29 weeks (95% confidence interval: 18-46 weeks). The global 1-year survival rate was 58%. CONCLUSION: Weekly docetaxel at a dosage of 40 mg/m(2) is a well-tolerated treatment, which has very promising activity on the reduction of PSA in metastatic HRPC. A large phase III study is underway.

RESUMO

BACKGROUND: The aim of this study was to analyze SCLC patients beyond 30 months, particularly their outcome, their way of life, and factors which could influence relapses, second-primary cancers and death. PATIENTS AND METHODS: Between January 1986 and May 1995, 263 SCLC patients who survived longer than 30 months were included from 52 French institutions. The analysis was performed on the 155 cases confirmed by a pathologic review. RESULTS: Physical, mental and psychological states were considered as normal at 30 months in respectively 70.3%, 87.7% and 67.7% of patients, not influenced by prophylactic cranial irradiation, number of chemotherapy cycles, CCNU or cisplatin. Therapeutic sequelae were neurological impairment (13%), pulmonary fibrosis (18%) and cardiac disorders (11%) at 30 months. Return to work was possible for 40% of patients in the first two years following diagnosis. Among 43 relapsing patients, 33 benefited from a second-line treatment. Their median survival was 12 months since retreatment, and seven patients have survived again longer than 30 months. Age > 60 at the time of diagnosis was found as an independent factor increasing the risk of relapse beyond 30 months (OR = 2.46, IC 95% (1.16-5.26), P = 0.01). The risk of relapse became less than 10% beyond five years. Twenty patients (13%) developed a second primary cancer in a mean time of 58.6 months. The risk of second primary cancer was increased by a number of chemotherapy cycles > 6 (OR = 3.25, IC 95% (1.08-9.8) P = 0.02) and by an age > 60 (OR = 2.92, IC 95% (1.07-7.97), P = 0.03). Five- and 10-year survival rates were respectively 68% and 44%. In these patients having reached a 30-month survival, three independent factors were predictive of a survival longer than five years: age < or = 60 at the time of diagnosis (OR = 2.85, IC 95% (1.23-6.6), P = 0.01), chest radiotherapy (OR = 3.1, IC 95% (1.28-7.69), P = 0.006) and absence of relapse (OR = 4.5, IC 95% (1.75-12.5), P = 0.002). This study suggests that: 1) therapeutic sequelae are rather mild, allowing return to work in 40% of patients; 2) relapsing 30-month survivors can benefit from second-line treatment; 3) SCLC cure can be achieved with a 10-year follow-up.

RESUMO

We report 2 cases of localized B-cell non-Hodgkin lymphoma occurring on the face in AIDS patients. The tumors were limited to the skin and bone, without other involvement. They were characterized by an aggressive local behavior that caused infectious and compressive complications and resulted in fatal outcome. Knowledge of the possibility that lymphoma may remain localized in AIDS patients should prompt clinicians to perform a biopsy as soon as possible, regardless of the CD4 count. Indeed, early diagnosis might increase the efficacity of treatment and might avoid disastrous local complications.

RESUMO

UNLABELLED: In both Phase III trials of vinorelbine-cisplatin (VP) versus single-agent vinorelbine, the received vinorelbine dose intensities were 18.8 and 21.1 mg/m2 per week in the VP arms. Vinorelbine was administered at the weekly dose of 30 mg/m2. A new structure of the vinorelbine-cisplatin regimen delivering alternating doses of vinorelbine (35 mg/m2 on weeks 1, 3, 5 and 17.5 mg/m2 on weeks 2 and 4) was reported to increase the vinorelbine dose intensity in patients with non-small cell lung cancer (NSCLC). To further analyze the ability of such an alternating vinorelbine schedule to enhance vinorelbine delivery, a Phase II study of VP was conducted in NSCLC patients using the previously published alternating doses of vinorelbine for 6 cycles. Cisplatin was administered on weeks 1, 5 and every 6 weeks thereafter, at a dose of 75 mg/m2 in the first 14 patients and at a dose of 100 mg/m2 in the 18 remaining patients. The intended vinorelbine dose intensity was 26.25 mg/m2 per week. The median delivered dose intensities of vinorelbine calculated during the first 8-week period were: all patients, 17.9 mg/m2 per week; patients treated with cisplatin 75 mg/m2, 18.1 mg/m2 per week; patients receiving cisplatin 100 mg/m2, 17.9 mg/m2 per week; naive patients 18.2 mg/m2 per week and previously treated patients. 13.2 mg/m2 per week. Reductions and delays in the vinorelbine treatment mostly occurred on weeks 3 and 7, which are times of high-dose treatments (35 mg/m2) according to the protocol. The partial response rate was 34% (95% C.I. = 26-42%). Median survival was 21 weeks. The main toxicities were febrile neutropenia (nine patients, including two septic deaths) and constipation Grades 3 and 4 (five patients). CONCLUSION: The use of alternating doses of vinorelbine within the VP regimen did not lead to higher vinorelbine delivered dose intensities than those reported with a standard weekly 30 mg/m2 administration.

RESUMO

Factor B (Bf) is a constituent of the alternative pathway of complement activation encoded within the major histocompatibility complex. Transcription of the murine gene from two initiation sites generates two Bf mRNA species differing in size and tissue distribution. Striking genetic, tissue-specific differences in Bf mRNA levels at extrahepatic sites (kidney and intestine) among mouse strains correlate with a DNA sequence polymorphism in the 5'-flanking region of the gene and differential nuclear protein binding at the Bf upstream transcriptional initiation site (UIS). To ascertain the functional consequences of this polymorphism in the Bf promoter, we analyzed the effects of strain-specific sequences in the Bf 5' region on the expression of a chloramphenicol acetyltransferase (CAT) reporter gene transfected in human and mouse hepatoma cells. The CAT activity and mRNA level produced when transcription was driven by the sequence of strains with high extrahepatic expression were reduced to background levels when the sequence specific to the low expressor strains was used. Eighty percent of this difference was accounted for by a point substitution that affects DNA-protein interaction at the UIS, the sequence of higher affinity conferring higher expression. Hepatocyte nuclear factor 4 (HNF-4), derived from HepG2, mouse liver and kidney or cell-free translation of HNF-4 RNA, is the nuclear protein that preferentially binds to the high expressor UIS. Bf-CAT is not expressed in cells that lack HNF-4 (CV-1). However, co-transfection of HNF-4 into CV-1 cells drives Bf-CAT expression and reproduces the differences derived from the substitution that affect HNF-4 binding in vitro. These data show that interaction of HNF-4 with polymorphic variants of the upstream Bf promoter is the major determinant of strain-specific extrahepatic factor B expression.

RESUMO

Simultaneous occurrence of subacute cutaneous lupus erythematosus and malignancy has rarely been reported. We report the first case of subacute cutaneous lupus erythematosus associated with Hodgkin's disease. Although our case does not fulfill the criteria of paraneoplastic process, a relationship between the two disorders might be suggested by their simultaneous occurrence and in view of the cases of disseminated lupus erythematosus associated with lymphoma reported so far. The different hypotheses are discussed.

RESUMO

Fluorescence in situ hybridization (FISH) was performed on bone marrow cells thought to contain a t(7;11)(p22;q13) from a patient with chronic myelomonocytic leukemia in transformation. FISH analysis using a panel of 10 probes previously mapped to 11q13 revealed a cytogenetically undetected complex rearrangement that involved chromosomes 7 and 11 as well as a chromosome 3 at band p24. Two distinct translocation breakpoints, both proximal to the BCL1 locus, were found in chromosome 11 that perforce separate it into three subregions. The two breakpoints appear distinct from the two previously described ones which involved the FAU and GSTP1 genes. Our observations add to the involvement of proximal 11q13 in myeloid malignancies.

RESUMO

Thirty-one patients with previously untreated advanced non-small cell lung cancer were included in a Phase I study to determine the optimal dose of Carboplatin (CBDCA) which preserves the best Navelbine (NVB) dose-intensity. NVB was administered at a 30-mg/m2 fixed-dose on days 1-8/q 3 weeks, whereas CBDCA doses were planned to be escalated from 275 to 400 mg/m2 on day 1/q 3 weeks for six successive groups of patients. The toxicity limiting dose of CBDCA in the combination was 350 mg/m2 on day 1/q 3 weeks because of repetitive Grade IV neutropenia, and the optimal dose of CBDCA was 325 mg/m2 on day 1/q3 weeks, offering a 86.4% NVB and a 92.6% CBDCA relative dose-intensity for the first 9 weeks. Responses were observed at each step. This study demonstrates the feasibility and the efficacy of the NVB-CBDCA combination. It suggests that dose-intensity calculation can be helpful to determine the recommended dose for Phase II studies of new drug combinations.

RESUMO

Chronic neutrophilic leukemia is an uncommon myeloproliferative disorder. We report a new case that fulfills the clinical and biologic criteria for such a diagnosis. The hematologic disease was revealed by a neutrophilic dermatosis that finally disappeared spontaneously after a duration of 1 year. Despite the lack of parallelism in the course of dermatologic and hematologic manifestations, we believe they were strongly linked. Occurrence of neutrophilic dermatoses in the course of other myeloproliferative disorders is well known. However, in our case, clinical and histologic features could not be used to distinguish between atypical Sweet's syndrome and specific cutaneous lesions because of the mature appearance of both skin and blood neutrophils.

RESUMO

A testicular tumour could be diagnosed by the occurrence of a Raynaud's phenomenon complicated by severe digital arteritis. The arteritis rapidly regressed under prostacyclin therapy. Such vascular manifestations are frequent in testicular carcinoma, but they usually develop after chemotherapy. To our knowledge, this is the first case where they preceded the diagnosis and specific treatment of a tumour of the testis.
