Development of the Anxiety, Depression and Coping (ADAF) screening tool for emotional and coping problems in cancer patients.

OBJECTIVE: Clinical guidelines recommend psychological screening in cancer patients. However, most scales cover many items and hamper detection. In addition, patients are generally referred from routine consultations. The specific objective of the present study was to develop and validate a tool, Anxiety, Depression, Coping (ADAF), to screen for anxiety and depression and assess coping in cancer patients. METHODS: Cross-sectional, multicenter study performed in the medical and radiotherapy-oncology services of five hospitals in Madrid and coordinated by the Medical Oncology Service of Hospital Clínico San Carlos (CEIC nº19/265-E). To determine psychometric properties, the ADAF screening questionnaire ADAF was administered. ADAF includes five items (1 related to anxiety symptoms, 2 related to depressive symptoms, 1 for helplessness coping, and 1 for avoidance coping). Hospital Anxiety and Depression Scale and Mini-Mental Adjustment to Cancer scale were used as the gold standards. Intraclass correlation coefficients were calculated and receiver operating characteristic (ROC) curves constructed. A p value of <0.05 was considered significant. RESULTS: A total of 186 patients completed the evaluation. The correlation coefficients were significant for all dimensions (anxiety, depression, helplessness coping, and avoidance coping) (p < 0.001). The statistical analysis of the ROC curves suggested that the cut-off point for screening was >2 points (3 in the case of depression), with a sensitivity and specificity between 62% and 90%, and an area under the curve above 0.8 for the first 4 items. CONCLUSIONS: ADAF screening has adequate reliability and good sensitivity and specificity. This instrument is useful and can be easily applied to identify emotional and coping problems in cancer patients.

Experience with eribulin in patients with metastatic breast cancer and associated hepatic impairment: case studies.

Hepatic impairment in breast cancer arises from metastatic spread of tumor cells to the liver and signals a poor prognosis. Systemic therapy is the mainstay of treatment. Three women with hepatic dysfunction secondary to breast cancer who were treated with eribulin are presented herein. In the first case, third-line eribulin at the time of acute liver failure due to metastases maintained response for up to 9 months with good tolerability. In the second case, a woman with secondary bone and liver disease had progression-free survival of 5 months to third-line eribulin and, upon rechallenge after a drug holiday, had almost four more months of stable disease. Last, a heavily pretreated patient with secondary bone and hepatic involvement showed a response to fourth-line eribulin.

Monitoring vascular normalization induced by antiangiogenic treatment with (18)F-fluoromisonidazole-PET.

BACKGROUND: Rationalization of antiangiogenics requires biomarkers. Vascular re-normalization is one widely accepted mechanism of action for this drug class. The interstitium of tumors with abnormal vasculature is hypoxic. We sought to track vascular normalization with (18)F-misonidazole ([18F]-FMISO, a probe that detects hypoxia) PET, in response to window-of-opportunity (WoO) treatment with the antiangiogenic dovitinib. METHODS: Two patient-derived pancreas xenografts (PDXs; Panc215 and Panc286) and the spontaneous breast cancer model MMTV-PyMT were used. Animals were treated during 1 week of WoO treatment with vehicle or dovitinib, preceded and followed by [18F]-FMISO-PET, [18F]-FDG-PET, and histologic assessment (dextran extravasation, hypoxia and microvessel staining, and necrosis, cleaved caspase-3 and Ki67 measurements). After WoO treatment, gemcitabine (pancreas)/adriamycin (breast) or vehicle was added and animals were treated until the humane endpoint. Tumor growth inhibition (TGI) and survival were the parameters studied. RESULTS: [18F]-FMISO SUV did not change after dovitinib-WoO treatment compared to vehicle-WoO (0.54 vs. 0.6) treatment in Panc215, but it decreased significantly in Panc286 (0.58 vs. 1.18; P < 0.05). In parallel, 10-KDa perivascular dextran extravasation was not reduced with dovitinib or vehicle-WoO treatment in Panc215, but it was reduced in Panc286. Whereas the addition of dovitinib to gemcitabine was indifferent in Panc215, it increased TGI in Panc286 (TGI switched from -59% to +49%). [18F]-FMISO SUV changes were accompanied by an almost 100% increase in interstitial gemcitabine delivery (665-1260 ng/mL). The results were validated in the PyMT model. CONCLUSIONS: [18F]-FMISO accurately monitored vascular re-normalization and improved interstitial chemotherapy delivery.

The NER-related gene GTF2H5 predicts survival in high-grade serous ovarian cancer patients.

OBJECTIVE: We aimed to evaluate the prognostic and predictive value of the nucleotide excision repair-related gene GTF2H5, which is localized at the 6q24.2-26 deletion previously reported by our group to predict longer survival of high-grade serous ovarian cancer patients. METHODS: In order to test if protein levels of GTF2H5 are associated with patients' outcome, we performed GTF2H5 immunohistochemical staining in 139 high-grade serous ovarian carcinomas included in tissue microarrays. Upon stratification of cases into high- and low-GTF2H5 staining categories (> and ≤ median staining, respectively) Kaplan-Meier and log-rank test were used to estimate patients' survival and assess statistical differences. We also evaluated the association of GTF2H5 with survival at the transcriptional level by using the on-line Kaplan-Meier plotter tool, which includes gene expression and survival data of 855 high-grade serous ovarian cancer patients from 13 different datasets. Finally, we determined whether stable short hairpin RNA-mediated GTF2H5 downregulation modulates cisplatin sensitivity in the SKOV3 and COV504 cell lines by using cytotoxicity assays. RESULTS: Low expression of GTF2H5 was associated with longer 5-year survival of patients at the protein (hazard ratio [HR], 0.52; 95% CI, 0.29 to 0.93; p=0.024) and transcriptional level (HR, 0.80; 95% CI, 0.65 to 0.97; p=0.023) in high-grade serous ovarian cancer patients. We confirmed the association with 5-year overall survival (HR, 0.55; 95% CI, 0.38 to 0.78; p=0.0007) and also found an association with progression-free survival (HR, 0.72; 95% CI, 0.54 to 0.96; p=0.026) in a homogenous group of 388 high-stage (stages III-IV using the International Federation of Gynecology and Obstetrics staging system), optimally debulked high-grade serous ovarian cancer patients. GTF2H5-silencing induced a decrease of the half maximal inhibitory concentration upon cisplatin treatment in GTF2H5-silenced ovarian cancer cells. CONCLUSION: Low levels of GTF2H5 are associated with enhanced prognosis in high-grade serous ovarian cancer patients and may contribute to cisplatin sensitization.

Mammographic density and breast cancer in women from high risk families.

INTRODUCTION: Mammographic density (MD) is one of the strongest determinants of sporadic breast cancer (BC). In this study, we compared MD in BRCA1/2 mutation carriers and non-carriers from BRCA1/2 mutation-positive families and investigated the association between MD and BC among BRCA1/2 mutation carriers per type of mutation and tumor subtype. METHODS: The study was carried out in 1039 female members of BRCA1 and BRCA2 mutation-positive families followed at 16 Spanish Genetic Counseling Units. Participants' density was scored retrospectively from available mammograms by a single blinded radiologist using a 5-category scale (<10 %, 10-25 %, 25-50 %, 50-75 %, >75 %). In BC cases, we selected mammograms taken prior to diagnosis or from the contralateral breast, whereas, in non-cases, the last screening mammogram was evaluated. MD distribution in carriers and non-carriers was compared using ordinal logistic models, and the association between MD and BC in BRCA1/2 mutation carriers was studied using logistic regression. Huber-White robust estimators of variance were used to take into account correlations between family members. A similar multinomial model was used to explore this association by BC subtype. RESULTS: We identified and scored mammograms from 341 BRCA1, 350 BRCA2 mutation carriers and 229 non-carriers. Compared to non-carriers, MD was significantly lower among BRCA2 mutation carriers (odds ratio (OR) =0.71; P-value=0.04), but not among BRCA1 carriers (OR=0.84; P-value=0.33). MD was associated with subsequent development BC (OR per category of MD=1.45; 95 % confidence interval=1.18-1.78, P-value<0.001), with no significant differences between BRCA1 and BRCA2 mutation carriers (P-value=0.48). Finally, no statistically significant differences were observed in the association of MD with specific BC subtypes. CONCLUSIONS: Our study, the largest to date on this issue, confirms that MD is an independent risk factor for all BC subtypes in either BRCA1 and BRCA2 mutation carriers, and should be considered a phenotype risk marker in this context.

Deletion at 6q24.2-26 predicts longer survival of high-grade serous epithelial ovarian cancer patients.

Standard treatments for advanced high-grade serous ovarian carcinomas (HGSOCs) show significant side-effects and provide only short-term survival benefits due to disease recurrence. Thus, identification of novel prognostic and predictive biomarkers is urgently needed. We have used 42 paraffin-embedded HGSOCs, to evaluate the utility of DNA copy number alterations, as potential predictors of clinical outcome. Copy number-based unsupervised clustering stratified HGSOCs into two clusters of different immunohistopathological features and survival outcome (HR = 0.15, 95%CI = 0.03-0.81; Padj = 0.03). We found that loss at 6q24.2-26 was significantly associated with the cluster of longer survival independently from other confounding factors (HR = 0.06, 95%CI = 0.01-0.43, Padj = 0.005). The prognostic value of this deletion was validated in two independent series, one consisting of 36 HGSOCs analyzed by fluorescent in situ hybridization (P = 0.04) and another comprised of 411 HGSOCs from the Cancer Genome Atlas study (TCGA) (HR = 0.67, 95%CI = 0.48-0.93, Padj = 0.019). In addition, we confirmed the association of low expression of the genes from the region with longer survival in 799 HGSOCs (HR = 0.74, 95%CI = 0.61-0.90, log-rank P = 0.002) and 675 high-FIGO stage HGSOCs (HR = 0.76, 95%CI = 0.61-0.96, log-rank P = 0.02) available from the online tool KM-plotter. Finally, by integrating copy number, RNAseq and survival data of 296 HGSOCs from TCGA we propose a few candidate genes that can potentially explain the association. Altogether our findings indicate that the 6q24.2-26 deletion is an independent marker of favorable outcome in HGSOCs with potential clinical value as it can be analyzed by FISH on tumor sections and guide the selection of patients towards more conservative therapeutic strategies in order to reduce side-effects and improve quality of life.
