Prognostic impact of BRCA1 pathogenic and BRCA1/BRCA2 unclassified variant mutations in patients with ovarian carcinoma

AbstractBACKGROUNDThe clinical relevance of BRCA1/2 alterations in ovarian carcinoma patients is debatable. Our aim was to determine factors influencing the risk of recurrence and death in ovarian carcinoma patients with BRCA pathogenic and unclassified variant mutations.METHODSA consecutive series of 205 women with primary ovarian carcinoma were screened for mutations in BRCA1 and BRCA2 genes using a conformational sensitive gel electrophoresis and direct sequencing. Data regarding medical and familial history were collected using questionnaires. Clinical and pathologic data were extracted from medical records.RESULTSUnclassified variant mutations in BRCA1 or BRCA2 genes were found in 16 (8%) patients, and BRCA1 pathogenic mutations were found in 18 (9%) patients. No pathogenic mutation was found in BRCA2 gene. Multivariate analysis showed that BRCA1 pathogenic mutation was an independent predictor of reduced risk of relapse and death (Hazard ratios [HR] 0.52 [confidence interval {CI} 0.28–0.98] and 0.38 [CI 0.10–0.96], respectively). Unclassified variant mutation did not affect recurrence and survival (HR 0.84 [CI 0.43–1.66] and 0.94 [CI 0.48–1.82], respectively). Other factors associated with reduced risk of relapse and death were complete pathologic remission at second‐look laparotomy and family history of breast and ovarian carcinoma, respectively. Recurrence and death outcomes among unclassified variant mutation carriers did not differ significantly from those in sporadic cases.CONCLUSIONSPatients with BRCA1 pathogenic mutation seem to have reduced risk of recurrence and death. These results should be interpreted with caution as they may be influenced by more intensive treatment, better response to cisplatin, and younger age of mutation carriers. Clinical relevance of BRCA1/2 unclassified variant mutations warrants further studies. Cancer 2005. © 2005 American Cancer Society.

AbstractBACKGROUNDAcute leukemia (AL) may occur as rare and late event of polycythemia vera (PV).METHODSThe current study included 23 patients who developed acute leukemia in a cohort of 414 consecutive PV patients with long‐term observation (3208 person years of follow‐up). Kaplan–Meier Product‐Limit method was used to estimate the cumulative probability of survival; Gehan–Wilcoxon test was applied to compare survival in different groups of patients.RESULTSMedian age was 68 years, and 18 patients (78%) were > 60 years of age. At diagnosis of AL, most patients had a white blood count > 10 × 109/L (n = 17; 74%), Hgb < 10 g/dL (n = 13; 57%), and platelet count > 50 × 109/L (n = 17; 74%). Of 14 patients in whom cytogenetic analysis was available at leukemic transformation, 12 showed high‐risk abnormalities including complex karyotype (n = 10), del (7)(q22) sole (n = 1) and del (X)(q26) sole (n = 1), whereas 2 had a normal karyotype. In patients whose karyotype was available at diagnosis of PV, cytogenetic evolution was documented at progression to AL. Treatment consisted of supportive care and/or low‐dose chemotherapy (n = 15), or induction chemotherapy (n = 8). This included idarubicin plus cytarabine (n = 3), high‐dose cytarabine (n = 4), and fludarabine‐based regimen (n = 1). Allogenic stem cell transplantation was offered to a single patient, who is alive at Day + 70. The outcome of patients was poor, with a median survival of 2.9 months (range, 0.6–20.1 mos), with no significant differences between palliation and intensive treatments.CONCLUSIONSAL following PV has distinct clinical and biologic features. Outcome of patients is poor irrespective of the treatment employed. Cancer 2005. © 2005 American Cancer Society.
Spectrum and prevalence of BRCA1 and BRCA2 germline mutations in Sardinian patients with breast carcinoma through hospital‐based screening

Published: July 2005

AbstractBACKGROUNDFactors that are predictive of carrying BRCA1 and BRCA2 germline mutations in patients with breast carcinoma are awaited widely. The genetically homogeneous Sardinian population may be useful for defining the role of such genetic alterations further through a clinical evaluation program.METHODSOne hundred two of 659 patients with breast carcinoma (15.5%) who were collected consecutively had a family history of breast carcinoma and were screened for BRCA1/2 mutations by denaturing high‐performance liquid chromatography and DNA sequencing.RESULTSThree deleterious germline BRCA1/2 mutations were detected in 15 of 102 families (14.7%), including 13 families (86.7%) with BRCA2 mutations and 2 families (13.3%) with BRCA1 mutations. A single variant, BRCA2‐8765delAG, was the most recurrent mutation in the series and was found in 12 of 102 families (11.8%) and in 18 of 657 patients (2.7%). The average age at diagnosis was significantly younger in families with BRCA1/2 mutations (48.6 yrs) compared with the age of patients who had no detectable mutation (52.9 yrs; P = 0.039). Moreover, BRCA1/2 mutations were found at a significantly higher rate in families who had at least 1 member with ovarian carcinoma or male breast carcinoma (5 of 12 families; 41.7%) than in families without such an association (10 of 90 families; 11.1%; P = 0.003).CONCLUSIONSBRCA2 mutations were approximately 6 times more prevalent than BRCA1 mutations. A diagnosis of breast carcinoma before age 50 years, ovarian carcinoma, male breast carcinoma, and 3 affected generations all were associated significantly with BRCA1/2 mutations. Although the current findings provided further support for the hypothesis that additional breast carcinoma susceptibility genes remain to be identified, such indicators of the presence of BRCA1/2 mutations may be useful in counseling patients about undergoing genetic testing.

Proton transfer chemical ionization mass spectrometry of fatty acid methyl esters separated by gas chromatography: quantitative aspects
Authors: Dodds Eric D. , McCoy Mark R. , Rea Lorrie D. , Kennish John M. 
Published: July 2005

AbstractThe propensity of esters to accept protons in the gas phase during chemical ionization (CI) mass spectrometry (MS) has been well known for some time. This proton transfer CI almost exclusively produces the [M+H]+ quasimolecular ion for most esters. While it has been suggested that this could serve as the basis for particularly sensitive quantitation of fatty acid methyl esters (FAME) separated by gas chromatography (GC), the application of this approach to quantitate FAME has not been fully explored. Here, we briefly address some considerations pertinent to the application of GC with proton transfer CI‐MS to quantitative analysis of FAME. Limits of detection and relative response factors (RF) for a number of FAME separated by GC and detected by CI‐MS are presented and discussed. While the detection limits are comparable or superior to other detection methods, it was noted that the RF for unsaturated FAME were dramatically reduced with increasing degree of unsaturation.
