RESUMO

Cervical cancer (CC) is the fourth most common cancer in women worldwide, strongly linked to high-risk human papilloma virus infection. In high-income countries, the screening programs have dramatically decreased the incidence of CC; however, the lack of accessibility to them in developing countries makes CC an important cause of mortality. Clinical stage is the most relevant prognostic factor in CC. The new FIGO staging system published in 2018 is more accurate than the previous one since it takes into account the lymph node status. In early stages, the primary treatment is surgery-with some concerns recently raised regarding minimally invasive surgery because it might decrease survival-or radiotherapy, whereas concomitant chemo-radiotherapy is the conventional approach in locally advanced stages. For recurrent or metastatic CC, the combination of chemotherapy plus bevacizumab is the preferred therapy. Immunotherapy approach based on checkpoint inhibitors is evolving as the election therapy following failure to platinum therapy.

RESUMO

Background: We hypothesized that the abundance of PD1 mRNA in tumor samples might explain the differences in overall response rates (ORR) observed following anti-PD1 monotherapy across cancer types. Patients and methods: RNASeqv2 data from 10 078 tumor samples representing 34 different cancer types was analyzed from TCGA. Eighteen immune-related gene signatures and 547 immune-related genes, including PD1, were explored. Correlations between each gene/signature and ORRs reported in the literature following anti-PD1 monotherapy were calculated. To translate the in silico findings to the clinical setting, we analyzed the expression of PD1 mRNA using the nCounter platform in 773 formalin-fixed paraffin embedded (FFPE) tumor samples across 17 cancer types. To test the direct relationship between PD1 mRNA, PDL1 immunohistochemistry (IHC), stromal tumor-infiltrating lymphocytes (sTILs) and ORR, we evaluated an independent FFPE-based dataset of 117 patients with advanced disease treated with anti-PD1 monotherapy. Results: In pan-cancer TCGA, PD1 mRNA expression was found strongly correlated (r > 0.80) with CD8 T-cell genes and signatures and the proportion of PD1 mRNA-high tumors (80th percentile) within a given cancer type was variable (0%-84%). Strikingly, the PD1-high proportions across cancer types were found strongly correlated (r = 0.91) with the ORR following anti-PD1 monotherapy reported in the literature. Lower correlations were found with other immune-related genes/signatures, including PDL1. Using the same population-based cutoff (80th percentile), similar proportions of PD1-high disease in a given cancer type were identified in our in-house 773 tumor dataset as compared with TCGA. Finally, the pre-established PD1 mRNA FFPE-based cutoff was found significantly associated with anti-PD1 response in 117 patients with advanced disease (PD1-high 51.5%, PD1-intermediate 26.6% and PD1-low 15.0%; odds ratio between PD1-high and PD1-intermediate/low = 8.31; P < 0.001). In this same dataset, PDL1 tumor expression by IHC or percentage of sTILs was not found associated with response. Conclusions: Our study provides a clinically applicable assay that links PD1 mRNA abundance, activated CD8 T-cells and anti-PD1 efficacy.

RESUMO

A pharmaceutical care programme was implemented at our hospital in early 2013. The main objectives were to analyse and describe the pharmaceutical interventions made, to calculate adherence, interventions and to evaluate patient satisfaction with the care programme. We performed a single-centre descriptive and prospective intervention in cancer patients who received oral chemotherapy as part of a clinical trial in 2013. Eighty-three patients were included. Median age was 58 years (range, 31-80) and 42 patients (50.6%) were men. We recorded 23 interventions, 13 of which were associated with drug interactions. The mean percentage of adherence was 98.9%. The interview with the pharmacist was considered to be very important by 84.6% of the respondents. A total of 92.3% said that they would like to speak to the pharmacist at subsequent visits. The doubts detected during the visits enable us to conclude that the information patients receive with respect to their study medication is usually incomplete. An integrated pharmaceutical care programme for cancer patients participating in clinical trials with oral cytostatic drugs was successful in terms of adherence and patient satisfaction and makes it possible to guarantee the safety and effectiveness of treatment on an individual basis.

RESUMO

PURPOSE: Immunotherapy (IT) agents and BRAF inhibitors (BRAFi) are effective treatments for patients with advanced BRAF-mutant melanoma although the optimal sequence remains to be elucidated. The aim of this study was to compare the outcomes of two different cohorts of patients treated with BRAFi first, then IT or the reverse sequence. PATIENTS AND METHODS: This is a retrospective study on two groups of patients: a cohort was treated first with BRAFi followed by immunotherapy (BRAFi-IT) and the other cohort with the reverse sequence (IT-BRAFi). Baseline characteristics and clinical outcomes were compared between the two cohorts. RESULTS: A total of 25 patients were included in the study. Sixteen patients were given BRAFi-IT sequence and nine received IT-BRAFi sequence. No differences were observed in the characteristics of patients prior to each treatment between cohorts. Objective response rate (ORR) achieved by BRAFi were not different among groups. ORR achieved by IT was higher when administered after BRAFi (43.8 vs 0 %). Survival rates at 1-2 years were similar in both cohorts and median overall survival was not different for BRAFi-IT and IT-BRAFi (log rank test p = 0.97). CONCLUSIONS: No differences were observed in OS between the two cohorts. These results support the indistinct use of IT or BRAFi as initial treatment in patients with metastatic BRAF-mutant melanoma, although higher rate of response to IT was observed when administered after BRAFi. Prospective randomized clinical trials are needed on this issue.

RESUMO

PIP: Proponents of Western-type feminism have failed to enlist most African women because this movement ignores the culture, tradition, mores and values, and political economies of African communities as well as the allegiance of African women to marriage as the foundation for society. Patricia McFadden, a feminist academic who writes monthly columns on gender issues, embodies this contradiction as she derides marriage as a millstone around women's necks and yet pronounces that she is a crusader for the restoration of traditional African culture. As human society evolved and developed an economy, joint labor was carried out first by the few dozen members of a clan and later by the larger tribes. The earliest clans were matriarchies. As production became more developed, patriarchies evolved. During this whole primitive, communal economic era, there were no class or gender distinctions. When specialization and barter emerged, surplus products created private property which, in turn, led to distinctions between people. The patriarchal society recognized women's natural role in procreation and allowed them release from work to have babies and nurture them. Since it would be foolish to invoke equal rights to erase maternity leave or avoid giving special considerations to pregnant working women, it follows that marriage is one of the human attributes which distinguishes man from animals. Thus, by abhorring the family organization of society, McFadden is neither an Africanist nor a feminist. Her definition of feminist is narrowed to educated single mothers of independent means; this eliminates nearly 80% of the women in the world. McFadden unjustly extrapolates her 3 months experience of marriage to that of every marriage; she projects her husband's boorish behavior on all husbands. This is no reason to encourage other women to give up the security they find in their marriages. Some African governments have already enacted laws to increase the legal status of women and enhance their income-producing activities. These changes have as their goal the greater opportunity for women to contribute to their families, not the opportunity for women to become independent of their families. Women have also become empowered academically through equal entry opportunities in schools at all levels. McFadden's advice is particularly dangerous in this era of HIV/AIDS. The dissolution of the family would also lead to increased numbers of juvenile delinquents with more children reared without the help of both parents. It is time for feminists to return to the basic moral order which honors marriage and the family.^ieng
