Malignant melanoma in Europe: changes in mortality rates (1970-90) in European Community countries

Reducing mortality, especially premature death, is a major goal of the fight against cancer. In this study, we have analyzed trends in malignant melanoma (MM) mortality in the European Community (EC) as a whole and for each country. The data (obtained from the World Health Organization data bank) have been analyzed for the period 1970-90, by age groups (20-44, 45-64, 65-74, 75+ years). Trends are presented as percentage change of mortality rate for each three-year period in comparison with the rate in the first one (1970-72). The mortality from MM in the EC as a whole increased for both genders (men, +89.2 percent; women, +72.6 percent), with statistically significant trends in all age classes. Northern countries experienced mortality changes about 30 to 50 percent less than the EC average increase. Greater changes were seen in southern European countries, in which recent standardized rates are near to those observed in northern European populations. Among Mediterranean people, the highest increase (more than fourfold) was observed in Spain. The significant increase found for the younger age class makes unlikely the risk of misclassification with other skin cancers. No future decrease in MM mortality in the EC is indicated from these data.     

Prognostic role of the recepteur d'origine nantais (RON) expression in ovarian cancer patients

ObjectiveThe aim of the study was to investigate the potential clinical relevance of immunohistochemically assessed RON expression in a large, single institution series of primary untreated advanced ovarian cancer patients.MethodsImmunohistochemical analysis was performed by using the polyclonal rabbit anti-RON-β antibody (C-20, clone sc-322, Santa Cruz, California). Results were expressed as the total proportion of immunostained tumor cells (RON positivity), or the percentage of cells showing strong staining of RON expression (H-RON positivity).ResultsIn the overall series RON positive immunoreaction was observed in 103/141 cases, while H-Ron positivity was detected in 577141 (40.4%) cases. No association between RON and H-RON expression with response to first-line treatment was documented. During the follow up period, progression and death of disease were observed in 111 (78.7%) and 76 (53.9%) cases, respectively. Cases with strong H-RON expression has a shorter overall survival (median = 35 months) than cases with low RON levels (median = 59 months) (X² = ? 2.1, p value = 0.032). In multivariate analysis, only platinum resistance, and extent of residual tumor retained an independent negative prognostic role for OS, with the percentages of H-RON positively immunostained cells showing a borderline statistical significance (p value = 0.0643). The unfavourable role of elevated percentages of H-RON expression was maintained only in the subgroup of platinum resistant recurrent ovarian cancer patients (X² = 3.89, p value = 0.048) compared to the platinum sensitive ones (X² = 1.98, p value = 0.16).ConclusionsThe assessment of RON expression deserves further attention as a parameter helpful to identify poor prognosis ovarian cancer patients potentially candidates to investigational agents.     

Quality of life and psychological distress in locally advanced cervical cancer patients administered pre-operative chemoradiotherapy

ObjectiveThe aim of the study was to analyze the Quality of life (QoL) scores in a single institution series of locally advanced cervical cancer patients (LACC) administered preoperative chemoradiation, compared to early stage disease (ECC) patients undergoing radical surgery.MethodsThe following criteria were required in order to enroll patients: age between 18 and 65years at initial diagnosis, at least 12months from the end of treatment, no evidence of recurrence/second malignancy. The SF-36 questionnaire on general health, and the HADS questionnaire on mental distress were utilized.Results93 subjects were available for the analysis. At time of analysis, median follow-up was 30months (range 12–120). LACC patients showed QoL scores comparable to ECC patients with the exception of physical functioning (mean ± SD = 69.0 ± 13.1 versus mean ± SD = 85.4 ± 16.2, p value = 0.0007). In the group of LACC patients, the presence of co-morbidities was significantly associated with the impairment of almost all subscales of QoL. A low education level and the status of unemployment were documented to negatively impact on the vast majority of SF-36 subscale scores. In the multivariate analysis, the presence of co-morbidities, low educational level, age> 50years, and unemployment maintained their independent negative association with poor QoL scores. The percentage of cases with high levels HADS-anxiety was higher in LACC than ECC patients (27.6% versus 8.6%, p value = 0.034).ConclusionsLACC patients administered preoperative chemoradiation showed QoL scores comparable to EEC patients, and a higher proportion of anxiety disorders; low educational level and unemployment status were mainly associated with poor QoL scores.     

Fetal facial profile in Pallister-Killian syndrome

Pallister-Killian syndrome (PKS) is a sporadic chromosomal anomaly, caused by a tissue-specific mosaic distribution of an additional isochromosome 12p. About 60 cases of prenatal diagnosis of PKS have been reported. Only 1 case of PKS is described on the basis of prenatal screening, presenting increased nuchal translucency. An abnormal fetal facial profile is described prenatally as sonographic evidence of PKS. We report a case of prenatal diagnosis in a fetus undergoing second-level scan due to positive triple screen with ultrasound features of PKS.     

Molecular analysis of the β-catenin gene in patients with the Mayer-Rokitansky-Küster-Hauser syndrome

Purpose

To study the β-catenin gene in a group of Mayer-Rokitansky-Küster-Hauser patients.

Methods

Twelve patients with the Mayer-Rokitansky-Küster-Hauser syndrome were included in this study. DNA was extracted from peripheral blood and the region codifying β-catenin GSK-3β phosphorylation sites on exon 3 was amplified. PCR products were purified and directly sequenced.

Results

No mutations were found in the GSK-3β phosphorylation sites on exon 3 of β-catenin gene in this group of patients with the MRKH syndrome.

Conclusions

β-catenin gene mutations are an unlikely cause of the MRKH syndrome.     

Impact of oncostatic treatments for childhood malignancies (radiotherapy and chemotherapy) on uterine competence to pregnancy

Fertility preservation in young girls affected by malignancies has got growing relevance in the last decade due to the improved survival chance of these patients after oncostatic treatments. Most studies have focused on preserving ovarian follicles and avoiding premature ovarian failure, whereas only a few have evaluated the effects exerted by radiotherapy and chemotherapy on the uterus. It is self-evident that fertility preservation after oncostatic therapies must include the maintenance of a functional uterus, and a certain degree of uterine damage must be considered when estimating reproductive prognosis in previously treated, childhood cancer survivors. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this article, the reader should be able to recall the growing number of children who survive oncostatic treatments, explain the possible effects on future reproductive endeavors, and summarize the possible ways to preserve fertility.
