High-dose melphalan and autologous stem cell transplantation as consolidation treatment in patients with chemosensitive ovarian cancer: results of a single-institution randomized trial.

The role of high-dose chemotherapy (HDCT) in epithelial ovarian cancer (EOC) remains controversial. This study was initiated to compare the efficacy and tolerability of HDCT as a consolidation approach in women with chemosensitive advanced EOC (FIGO stages IIC-IV). Patients who had achieved their first clinical complete remission after six cycles of conventional paclitaxel and carboplatin combination chemotherapy were randomly assigned to receive or not high-dose melphalan. The primary objective was to compare time to disease progression (TTP). A total of 80 patients were enrolled onto the trial. Patients who were randomized to receive HDCT were initially treated with cyclophosphamide 4 g/m(2) for PBPC mobilization. HDCT consisted of melphalan 200 mg/m(2). Of the 37 patients who were allocated to HDCT, 11 (29.7%) did not receive melphalan either due to patient refusal (n=5) or due to failure of PBPC mobilization (n=6). In an intent-to-treat analysis, there were no significant differences between the two arms in TTP (P=0.059) as well as in overall survival (OS) (P=0.38).

Can local application of imiquimod cream be an alternative mode of therapy for patients with high-grade intraepithelial lesions of the vagina?

The aim of the present study was to assess the local application of imiquimod cream 5% as an alternative mode of therapy for high-grade vaginal intraepithelial neoplasia (VAIN 2/3). Positive human papillomavirus (HPV) patients with multifocal high-grade VAIN (2/3) not involving the vaginal vault in hysterectomized patients took part in this study. The treatment consisted of vaginal application of the cream under colposcopic guidance. Following management, biopsies were obtained from the previously recorded lesions. p53 expression was recorded prior and after therapy. Seven patients with VAIN 2/3 took part in this study. Six patients (86%) were positive for high-risk HPV type while three (43%) women who were positive for p53 nuclei prior to therapy were found to be negative following treatment. After treatment, 86% of the patients were found to have either HPV infection or low-grade VAIN. During follow-up, two patients (28.5%) were managed by vaginectomy, one for persistent and one for recurrent high-grade VAIN. Currently, from the five patients that are followed, three have simple HPV infection and two, VAIN 1. Imiquimod cream 5% might represent an alternative although not permanent method of management in young, HPV-positive women with multifocal high-grade lesions of the vagina (VAIN 2/3).

Maternal - neonatal folate and vitamin B12 serum concentrations in Greeks and in Albanian immigrants.

BACKGROUND: Low folate and vitamin B(12) concentrations during pregnancy are implicated with neural tube defects (NTD) and neurological manifestations in the neonates. AIM: To compare serum concentrations of folate and vitamin B(12) in 1025 Greek mothers, 908 immigrant Albanian mothers at delivery and in the cord blood of their neonates. METHODS: A 30 days food diary was kept from each mother. Folate and vitamin B(12) sera concentrations were measured with Bayer ADVIA Centaur System. RESULTS: Energy, carbohydrates and total fat intake were significantly higher in Albanian mothers when compared with those of Greek origin. On the contrary, total protein, and especially animal protein intake were higher in the Greek mothers. Folate intake was similar between the two ethnic groups whereas vitamin B(12) intake in Albanians was evaluated lower (1.8 +/- 0.13 microg day(-1)) when compared with that of Greeks (2.8 +/- 0.12 microg day(-1); P < 0.001). Folate serum concentrations in mothers and newborns were similar (17.7 +/- 9.1 and 26.5 +/- 15.2 nm versus 18.1 +/- 8.6 and 24.6 +/- 14.7 nm, respectively P > 0.05) in the two ethnic groups. In contrast, vitamin B(12) serum concentration was significantly lower (135.0 +/- 19.6 pm) in the Albanian mothers compared with that of Greeks (164.5 +/- 17.7 pm, P < 0.0001). Consequently, the vitamin concentrations was found lower in the newborns of Albanian origin (133.6 +/- 11.8 pm) compared with that of Greek neonates (213.3 +/- 11.4 pm, P < 0.0001). CONCLUSIONS: (a) Folate serum concentrations in Greek and Albanian mothers and in their neonates were similar, (b) vitamin B(12) serum concentrations, evaluated for first time in these ethnic groups, were significantly low in Albanians, both in mothers and newborns, (c) the low protein and especially the reduced animal protein intake from the Albanian mothers, possibly due to their low socio-economic status, may be responsible for their decreased vitamin B(12) serum concentrations and (d) vitamin B(12) supplementation along with an increase of animal protein intake might improve the vitamin serum status in the Albanians.

Maternal--neonatal serum selenium and copper levels in Greeks and Albanians.

AIM: To evaluate selenium (Se) and copper (Cu) concentrations in Greek and Albanian immigrant mothers and in the cord blood of their newborns. SUBJECTS AND METHODS: From 1118 Greek and 820 Albanian mothers and from the cord blood of their neonates blood was obtained for Se and Cu measurement. Se and Cu concentrations were determined in sera with graphite furnace atomic absorption spectroscopy (GFAAAS) and atomic absorption spectrometry, respectively. In all, 30 days' nutrient intakes were evaluated in both groups. RESULTS: Animal protein, Se and Cu intakes were poor in the Albanians vs the Greeks (P < 0.001). Se concentrations in the Greek mothers (68.3 +/- 8.5 microg/l) and in their newborns (37.02 +/- 8.9 microg/l) were found higher as compared with those in Albanian mothers (37.4 +/- 9.9 microg/l) and in their newborns (34.3 +/- 9.1 microg/l) (P < 0.001). Cu levels were also found higher (P < 0.001) in the Greek mothers (1687 +/- 353 microg/l) and in their neonates (449 +/- 87 microg/l) compared with those in the Albanian mothers (959 +/- 318 microg/l) and in their newborns (229 +/- 67 microg/l). Additionally, 31.5% of neonates born to Albanian women with Se concentrations less than 28 microg/l had higher Se levels (P < 0.01) than their mothers. CONCLUSIONS: The low Se and Cu levels evaluated in the Albanian mothers and their newborns could be related to their poor animal protein intake which could be the consequence of their low socioeconomic status. As an effective preventive measure, accurate dietetic strategies to assess the requirements of pregnant immigrant women for trace elements may be planned in Greece.
