RESUMEN

OBJECTIVE: To describe the baseline symptom burden(SB) experienced by patients(pts) with recurrent ovarian cancer(ROC) prior and associations with progression free survival (PFS) and overall survival (OS). METHODS: We analysed baseline SB reported by pts. with platinum resistant/refractory ROC (PRR-ROC) or potentially­platinum sensitive ROC receiving their third or greater line of chemotherapy (PPS-ROC≥3) enrolled in the Gynecologic Cancer InterGroup - Symptom Benefit Study (GCIG-SBS) using the Measure of Ovarian Symptoms and Treatment concerns (MOST). The severity of baseline symptoms was correlated with PFS and OS. RESULTS: The 948 pts. reported substantial baseline SB. Almost 80% reported mild to severe pain, and 75% abdominal symptoms. Shortness of breath was reported by 60% and 90% reported fatigue. About 50% reported moderate to severe anxiety, and 35% moderate to severe depression. Most (89%) reported 1 or more symptoms as moderate or severe, 59% scored 6 or more symptoms moderate or severe, and 46% scored 9 or more symptoms as moderate or severe. Higher SB was associated with significantly shortened PFS and OS; five symptoms had OS hazard ratios larger than 2 for both moderate and severe symptom cut-offs (trouble eating, vomiting, indigestion, loss of appetite, and nausea; p < 0.001). CONCLUSION: Pts with ROC reported high SB prior to starting palliative chemotherapy, similar among PRR-ROC and PPS-ROC≥3. High SB was strongly associated with early progression and death. SB should be actively managed and used to stratify patients in clinical trials. Clinical trials should measure and report symptom burden and the impact of treatment on symptom control.

RESUMEN

PURPOSE: The Measure of Ovarian Symptoms and Treatment (MOST) concerns is a validated patient-reported symptom assessment tool for assessing symptom benefit and adverse effects of palliative chemotherapy in women with recurrent ovarian cancer (ROC). We aimed to examine (i) how symptoms within MOST symptom indexes track together (i.e. co-occur) and (ii) the association between MOST symptom indexes and key aspects of health-related quality of life (HRQL). METHOD: A prospective cohort of women with ROC completed the MOST-T35, EORTC QLQ-C30 and EORTC QLQ-OV28 at baseline and before each cycle of chemotherapy. Analyses were conducted on baseline and end-of-treatment data. Exploratory factor analysis and hierarchical cluster analysis identified groups of co-occurring symptoms. Path models examined associations between MOST symptom indexes and HRQL. RESULTS: Data from 762 women at baseline and 681 at treatment-end who completed all 22 symptom-specific MOST items and at least one HRQL measure were analysed. Four symptom clusters emerged at baseline and treatment-end: abdominal symptoms, symptoms associated with peripheral neuropathy, nausea and vomiting, and psychological symptoms. Psychological symptoms (MOST-Psych) and symptoms due to disease (ovarian cancer) or treatment (MOST-DorT) were associated with poorer scores on QLQ-C30 and OV28 functioning domains and worse overall health at both time points. CONCLUSION: Four MOST symptom clusters were consistent across statistical methods and time points. These findings suggest that routine standardized assessment of psychological and physical symptoms in clinical practice with MOST plus appropriate symptom management referral pathways is an intervention for improving HRQL that warrants further research.

RESUMEN

OBJECTIVE: The Gynecologic Cancer InterGroup (GCIG)-Symptom Benefit Study was designed to evaluate the effects of chemotherapy on symptoms and health-related quality of life (HRQL) in women having chemotherapy for platinum resistant/refractory recurrent ovarian cancer (PRR-ROC) and potentially platinum sensitive with ≥3 lines of chemotherapy (PPS-ROC ≥3). METHODS: Participants completed the Measure of Ovarian Cancer Symptoms and Treatment (MOST) and European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire QLQ-C30 questionnaires at baseline and every 3-4 weeks until progression. Participants were classified symptomatic if they rated ≥4 of 10 in at least one-third of symptoms in the MOST index. Improvement in MOST was defined as two consecutive scores of ≤3 in at least half of the symptomatic items at baseline. Improvement in HRQL was defined as two consecutive scores ≥10 points above baseline in the QLQ-C30 summary score scale (range 0-100). RESULTS: Of 948 participants enrolled, 910 (96%) completed baseline questionnaires: 546 with PRR-ROC and 364 with PPS-ROC ≥3. The proportions of participants symptomatic at baseline as per MOST indexes were: abdominal 54%, psychological 53%, and disease- or treatment-related 35%. Improvement was reported in MOST indexes: abdominal 40%, psychological 35%, and disease- or treatment-related 38%. Median time to improvement in abdominal symptoms occurred earlier for PRR-ROC than for PPS-ROC ≥3 (4 vs 6 weeks, p=0.044); median duration of improvement was also similar (9.0 vs 11.7 weeks, p=0.65). Progression-free survival was longer among those with improvement in abdominal symptoms than in those without (median 7.2 vs 2.5 months, p<0.0001). Improvements in HRQL were reported by 77/448 (17%) with PRR-ROC and 61/301 (20%) with PPS-ROC ≥3 (p=0.29), and 102/481 (21%) of those with abdominal symptoms at baseline. CONCLUSION: Over 50% of participants reported abdominal and psychological symptoms at baseline. Of those, 40% reported an improvement within 2 months of starting chemotherapy. Approximately one in six participants reported an improvement in HRQL. Symptom monitoring and supportive care is important as chemotherapy palliated less than half of symptomatic participants.

RESUMEN

PURPOSE: This paper illustrates a conceptual model for a new patient-reported outcome measure (PROM) aimed at measuring financial toxicity (FT) in oncological setting in Italy, where citizens are provided universal healthcare coverage. METHODS: Focus groups with overall 34 patients/caregivers in three different Italian centers (from Northern, Centre, and Southern Italy) and an open-ended survey with 97 medical oncologists were undertaken. Transcripts from focus groups and the open-ended survey were analyzed to identify themes and links between themes. Themes from the qualitative research were supplemented with those reported in the literature; concepts identified formed the basis for item development that were then tested through the importance analysis (with 45 patients) and the cognitive debriefing (with other 45 patients) to test relevance and comprehension of the first draft PRO instrument. RESULTS: Ten domains were extracted by analyzing 156 concepts generated from focus groups and the open-ended survey. After controlling for redundancy, 55 items were generated and tested through the importance analysis. After controlling comprehension and feasibility through cognitive debriefing interviews, a first version of the questionnaire consisting of 30 items was devised. CONCLUSIONS: This qualitative study represents the first part of a study conducted to develop a new PROM to assess FT in Italy, by using a bottom-up approach that makes the most of patients' experiences and the health system analysis. TRIAL REGISTRATION: clinicaltrials.gov NCT03473379 first posted on March 22, 2018.

RESUMEN

PURPOSE: Gynecologic Cancer Intergroup Symptom Benefit Study (GCIG-SBS) Stage 2 aimed to review, revise, and validate a patient-reported outcome measure (PROM), the Measure of Ovarian Symptoms and Treatment concerns (MOST), developed in GCIG-SBS Stage 1 (MOSTv1, 35 items), and document recurrent ovarian cancer (ROC) symptom burden and benefit. METHODS: GCIG-SBS Stage 2 recruited patients with platinum-resistant/refractory ROC (PRR-ROC) or potentially platinum-sensitive ROC with ≥ 3 lines of prior chemotherapy (PPS-ROC ≥ 3). Patients completed MOSTv1, QLQ-C30, QLQ-OV28, and FACT-O/FOSI at baseline and before cycle 3 of chemotherapy (pre-C3), and global assessments of change (MOST-Change) pre-C3. Clinicians rated patients' cancer-related symptoms, performance status, and adverse events. Convergent and divergent validity (Spearman's correlations), discriminative validity (effect sizes between groups classified by clinician-rated characteristics), and responsiveness (paired t tests in patients expected to experience clinically meaningful change) were assessed. RESULTS: Of 948 recruits, 903 completed PROMs at baseline and 685 pre-C3. Baseline symptom burden was substantial for PRR-ROC and PPS-ROC ≥ 3. MOSTv2 has 24 items and five multi-item scales: abdominal symptoms (MOST-Abdo), disease or treatment-related symptoms (MOST-DorT), chemotherapy-related symptoms (MOST-Chemo), psychological symptoms (MOST-Psych), and MOST-Well-being. Correlations confirmed concurrent and divergent validity. Discriminative validity was confirmed by effect sizes that conformed with a priori hypotheses. MOST-Abdo was responsive to improvements in abdominal symptoms and MOST-Chemo detected the adverse effects of chemotherapy. CONCLUSIONS: The MOSTv2 validly quantifies patient-reported symptom burden, adverse effects, and symptom benefit in ROC, and as such is fit-for-purpose for clinical trials of palliative chemotherapy in ROC. Further research is required to assess test-retest reliability.

RESUMEN

PURPOSE: Dermatologic adverse events (dAEs) in cancer treatment are frequent with the use of targeted therapies. These dAEs have been shown to have significant impact on health-related quality of life (HRQoL). While standardized assessment tools have been developed for physicians to assess severity of dAEs, there is a discord between objective and subjective measures. The identification of patient-reported outcome (PRO) instruments useful in the context of targeted cancer therapies is therefore important in both the clinical and research settings for the overall evaluation of dAEs and their impact on HRQoL. METHODS: A comprehensive, systematic literature search of published articles was conducted by two independent reviewers in order to identify PRO instruments previously utilized in patient populations with dAEs from targeted cancer therapies. The identified PRO instruments were studied to determine which HRQoL issues relevant to dAEs were addressed, as well as the process of development and validation of these instruments. RESULTS: Thirteen articles identifying six PRO instruments met the inclusion criteria. Four instruments were general dermatology (Skindex-16©, Skindex-29©, Dermatology Life Quality Index (DLQI), and DIELH-24) and two were symptom-specific (functional assessment of cancer therapy-epidermal growth factor receptor inhibitor-18 (FACT-EGFRI-18) and hand-foot syndrome 14 (HFS-14)). CONCLUSIONS: While there are several PRO instruments that have been tested in the context of targeted cancer therapy, additional work is needed to develop new instruments and to further validate the instruments identified in this study in patients receiving targeted therapies.

RESUMEN

Clear cell carcinomas of the uterine corpus and cervix are rare gynecological cancers with limited information regarding the pathogenesis and biology. At present, the approach to management is the same as for patients with the more common histological subtypes of endometrioid endometrial cancer and adenocarcinoma of the cervix. Surgical resection is the standard treatment for patients with early-stage disease, but there is no evidence-based approach to direct the management of patients with more advanced-stage disease at presentation or with recurrent disease. We review the epidemiology, pathology, and what is known about both uterine corpus and cervical clear cell cancers and make management recommendations.

RESUMEN

Clear cell carcinoma of the ovary (CCC) is a histologic subtype of epithelial ovarian cancer with a distinct clinical behavior. There are marked geographic differences in the prevalence of CCC. The CCC is more likely to be detected at an early stage than high-grade serous cancers, and when confined within the ovary, the prognosis is good. However, advanced disease is associated with a very poor prognosis and resistance to standard treatment. Cytoreductive surgery should be performed for patients with stage II, III, or IV disease. An international phase III study to compare irinotecan/cisplatin and paclitaxel/carboplatin as adjuvant chemotherapy for stage IIV CCC has completed enrollment (GCIG/JGOG3017). Considering the frequent PIK3CA mutation in CCC, dual inhibitors targeting PI3K, AKT in the mTOR pathway, are promising. Performing these trials and generating the evidence will require considerable international collaboration.

RESUMEN

PURPOSE: Cancer-related fatigue (CRF) is one of the most common symptoms experienced by cancer patients (CPs). The Brief Fatigue Inventory (BFI) is a reliable instrument to assess CRF in CPs. The aim of this study was to evaluate the psychometric properties of the Italian version of the BFI (BFI-I). METHODS: The BFI-I was developed by using the forward-backward translation approach. The psychometric properties of the BFI-I were assessed in terms of acceptability, internal consistency, and validity. Outpatient CPs filled in BFI-I along with the Medical Outcome Study Quality of Life Short Form 36 (SF36). Demographic and health data were collected. RESULTS: The BFI-I had an overall Cronbach alpha for the nine items of 0.94. The inter-item mean correlation was 0.64, and coefficients ranged from 0.47 to 0.81 for the nine items. The results of the factor analysis suggested a 1-factor solution explaining 68 % of the variance, supporting the hypothesis of unidimensionality of the BFI-I. The BFI-I score was compared to SF36 subscales score to evaluate concurrent validity. An expected inverse correlation between the BFI-I and the vitality subscale of the SF36 was observed (r = -0.67, 95 % confidence interval -0.73 to -0.59). The correlation with the other subscales of the SF36 ranged between -0.56 and -0.13. Discriminant validity analysis showed the BFI-I mean score significantly increased with increasing Eastern Cooperative Oncology Group values (p < 0.001). CONCLUSIONS: BFI-I is a clinical instrument with satisfactory psychometric properties to assess CRF in Italian CPs.

RESUMEN

Radiation dermatitis (RD) results from radiotherapy and often occurs within the first 4 weeks of treatment, although late effects also occur. While RD may resolve over time, it can have a profound effect on patients' quality of life and lead to dose modifications. A study group of international, interdisciplinary experts convened to develop RD prevention and treatment guidelines based on evidence from randomized, controlled trials. Evidence-based recommendations were developed after an extensive literature review. Randomized, controlled trials with standardized measurement of outcomes were considered the best evidence, and a majority of the recommendations were formulated from this literature. The adoption of washing with water, with or without a mild soap, and allowing the use of antiperspirants is supported by randomized trials. Use of topical prophylactic corticosteroids (mometasone) is recommended to reduce discomfort and itching. There is some evidence that silver sulfadiazine cream can reduce dermatitis score. There is insufficient evidence to support, and therefore the panel recommends against the use of trolamine, topical sulcrate, hyaluronic acid, ascorbic acid, silver leaf dressing, light-emitting diode lasers, Theta cream, dexpanthenol, calendula, proteolytic enzymes, sulcralfate, oral zinc, and pentoxifylline. Moreover, there is no evidence to support the superiority for any specific intervention in a reactive fashion. For patients with established radiation-induced telangiectasia and fibrosis, the panel suggests the use of pulse dye laser for visual appearance, and the use of pentoxifylline and vitamin E for the reduction of fibrosis.

RESUMEN

The European Network for Gynaecological Oncological Trial groups (ENGOT) is a research network of the European Society of Gynaecological Oncology and was founded in Berlin in October 2007. Earlier, we reported on the ENGOT minimal requirements for trials between academic groups and pharmaceutical companies. In this paper, we summarize the roadmap for performing trials in the ENGOT framework. In this roadmap, we define how an ENGOT trial should be set up and discuss the following items: What are the conditions to classify a study as an ENGOT trial? What is an ENGOT protocol? How are an ENGOT protocol, informed consent (ICF), and case report form (CRF) produced? How is the center selection and feasibility performed in ENGOT trials? How are regulatory and operational tasks handled? How should a confidentiality agreement between the industry and the whole ENGOT network be negotiated? How are contracts made between the industry and ENGOT and between ENGOT groups? How are funding, insurance, and communication flow arranged in ENGOT trials? What are the requirements for conducting substudies and what are the tasks for the leading group in an ENGOT trial? A template of a confidentiality agreement, a checklist of ENGOT criteria for new study proposals, and guidelines for authorship are also provided.

RESUMEN

INTRODUCTION: US National Cancer Institute's (NCI) Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE®) is a library of 78 symptom terms and 124 items enabling patient reporting of symptomatic adverse events in cancer trials. This multicenter study used mixed methods to develop an Italian language version of this widely accepted measure, and describe the content validity and reliability in a diverse sample of Italian-speaking patients. METHODS: All PRO-CTCAE items were translated in accordance with international guidelines. Subsequently, the content validity of the PRO-CTCAE-Italian was explored and iteratively refined through cognitive debriefing interviews. Participants (n=96; 52% male; median age 64 years; 26% older adults; 18% lower educational attainment) completed a PRO-CTCAE survey and participated in a semi-structured interview to determine if the translation captured the concepts of the original English language PRO-CTCAE, and to evaluate comprehension, clarity and ease of judgement. Test-retest reliability of the finalized measure was explored in a second sample (n=135). RESULTS: Four rounds of cognitive debriefing interviews were conducted. The majority of PRO-CTCAE symptom terms, attributes and associated response choices were well-understood, and respondents found the items easy to judge. To improve comprehension and clarity, the symptom terms for nausea and pain were rephrased and retested in subsequent interview rounds. Test-retest reliability was excellent for 41/49 items (84%); the median intraclass correlation coefficient was 0.83 (range 0.64-0.94). DISCUSSION: Results support the semantic, conceptual and pragmatic equivalence of PRO-CTCAE-Italian to the original English version, and provide preliminary descriptive evidence of content validity and reliability.

RESUMEN

Compelling evidence has emerged in recent years indicating that stromal cells play a critical role in disease progression. CXCR4 is a G-protein-coupled receptor with a major role in lymphocyte homing. Its ligand, CXCL12, is a highly efficient chemotactic factor for T cells, monocytes, pre-B cells, dendritic cells and myeloid bone marrow-derived cells (BMDCs). In addition, the CXCR4-CXCL12 axis plays a central role in tumor growth and metastasis. To evaluate the effect of genetic CXCR4 reduction on metastasis development, murine melanoma B16 cells were injected into the tail vein of C57BL/6 CXCR4(+/+) and CXCR4(+/-) mice in the presence of the CXCR4 inhibitor, Plerixafor (previously named AMD3100). Although lung metastases developed in wild-type CXCR4(+/+) and heterozygote CXCR4(+/-) mice, nodules were significantly smaller in the latter. CXCR4 pharmacological inhibition by Plerixafor further reduced lung metastases in CXCR4(+/-) mice, preserving the pulmonary architecture (4.18 ± 1.38 mm(2) vs. 1.11 ± 0.60 mm(2), p = 0.038). A reduction in LY6G-positive myeloid/granulocytic cells and in p38 MAPK activation was detected in lungs from CXCR4(+/-) mice compared to CXCR4(+/+) mice [LY6G-positive myeloid CXCR4(+/-) vs. CXCR4(+/+) (p = 0.0004); CXCR4(+/+) vs. CXCR4(+/+) Plerixafor-treated (p = 0.0031)] suggesting that CXCR4 reduction on myeloid-derived cells reduced their recruitment to the lung, consequently impairing lung metastases. Our findings argue in favor of a specific role of CXCR4 expressed in stromal cells that condition the pro-tumor microenvironment. In this scenario, CXCR4 antagonists will target neoplastic cells as well as the pro-tumor stromal microenvironment.

RESUMEN

Gefitinib is an oral, reversible, tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR) that plays a key role in the biology of non small cell lung cancer (NSCLC). Phase I studies indicated that the recommended dose of gefitinib was 250 mg/day. Rash, diarrhea, and nausea were the most common adverse events. The positive results obtained in early phase 2 clinical trials with gefitinib were not confirmed in large phase 3 trials in unselected patients with advanced NSCLC. The subsequent discovery that the presence of somatic mutations in the kinase domain of EGFR strongly correlates with increased responsiveness to EGFR tyrosine kinase inhibitors prompted phase 2 and 3 trials with gefitinib in the first line-treatment of EGFR-mutated NSCLC. The results of these trials have demonstrated the efficacy of gefitinib that can be now considered as the standard first-line treatment of patients with advanced NSCLC harbouring activating EGFR mutations.

RESUMEN

BACKGROUND: Epidermal growth factor receptor inhibitors (EGFRI) produce various dermatologic side effects in the majority of patients, and guidelines are crucial for the prevention and treatment of these untoward events. The purpose of this panel was to develop evidence-based recommendations for EGFRI-associated dermatologic toxicities. METHODS: A multinational, interdisciplinary panel of experts in supportive care in cancer reviewed pertinent studies using established criteria in order to develop first-generation recommendations for EGFRI-associated dermatologic toxicities. RESULTS: Prophylactic and reactive recommendations for papulopustular (acneiform) rash, hair changes, radiation dermatitis, pruritus, mucositis, xerosis/fissures, and paronychia are presented, as well as general dermatologic recommendations when possible. CONCLUSION: Prevention and management of EGFRI-related dermatologic toxicities is critical to maintain patients' health-related quality of life and dose intensity of antineoplastic regimens. More rigorous investigation of these toxicities is warranted to improve preventive and treatment strategies.

RESUMEN

Embryo-fetal experimentation is intuitively associated with a therapeutic intent, according to a consolidated line of thought on the international and national levels. We report on a researcher's request for Ethics Committee approval to perform intrauterine transplantation of stem cells via cordocentesis on a fetus diagnosed with dystrophic epidermolysis bullosa, using stem cells obtained from a sibling's umbilical cord blood. The Ethics Committee rejected the request because of deontological issues and clinical judgments about the potential good to be derived from the procedure. In particular, in this case there was no preclinical or animal research on the procedure, the risk factors for mother and fetus were unknown, there was no way to guarantee compliance with Italian laws regarding safety and quality of the donor cells, and there was lack of clear informed consent.

OBJECTIVES: To measure and explain financial toxicity (FT) of cancer in Italy, where a public healthcare system exists and patients with cancer are not expected (or only marginally) to pay out-of-pocket for healthcare. SETTING: Ten clinical oncological centres, distributed across Italian macroregions (North, Centre, South and Islands), including hospitals, university hospitals and national research institutes. PARTICIPANTS: From 8 October 2019 to 11 December 2019, 184 patients, aged 18 or more, who were receiving or had received within the previous 3 months active anticancer treatment were enrolled, 108 (59%) females and 76 (41%) males. INTERVENTION: A 30-item prefinal questionnaire, previously developed within the qualitative tasks of the project, was administered, either electronically (n=115) or by paper sheet (n=69). PRIMARY AND SECONDARY OUTCOME MEASURES: According to the protocol and the International Society for Pharmacoeconomics and Outcomes Research methodology, the final questionnaire was developed by mean of explanatory factor analysis and tested for reliability, internal consistency (Cronbach's α test and item-total correlation) and stability of measurements over time (test-retest reliability by intraclass correlation coefficient and weighted Cohen's kappa coefficient). RESULTS: After exploratory factor analysis, a score measuring FT (FT score) was identified, made by seven items dealing with outcomes of FT. The Cronbach's alpha coefficient for the FT score was 0.87 and the item-total correlation coefficients ranged from 0.53 to 0.74. Further, nine single items representing possible determinants of FT were also retained in the final instrument. Test-retest analysis revealed a good internal validity of the FT score and of the 16 items retained in the final questionnaire. CONCLUSIONS: The Patient-Reported Outcome for Fighting FInancial Toxicity (PROFFIT) instrument consists of 16 items and is the first reported instrument to assess FT of cancer developed in a country with a fully public healthcare system. TRIAL REGISTRATION NUMBER: NCT03473379.

RESUMEN

Vandetanib is a novel, orally available inhibitor of different intracellular signaling pathways involved in tumor growth, progression, and angiogenesis: vascular endothelial growth factor receptor-2, epidermal growth factor receptor, and REarranged during Transfection tyrosine kinase activity. Phase I clinical trials have shown that vandetanib is well tolerated as a single agent at daily doses < or =300 mg. In the phase II setting, negative results were observed with vandetanib in small cell lung cancer, metastatic breast cancer, and multiple myeloma. In contrast, three randomized phase II studies showed that vandetanib prolonged the progression-free survival (PFS) time of patients with non-small cell lung cancer (NSCLC) as a single agent when compared with gefitinib or when added to chemotherapy. Rash, diarrhea, hypertension, fatigue, and asymptomatic QTc prolongation were the most common adverse events. Antitumor activity was also observed in medullary thyroid cancer. Four randomized phase III clinical trials in NSCLC are exploring the efficacy of vandetanib in combination with docetaxel, the Zactima in cOmbination with Docetaxel In non-small cell lung Cancer (ZODIAC) trial, or with pemetrexed, the Zactima Efficacy with Alimta in Lung cancer (ZEAL) trial, or as a single agent, the Zactima Efficacy when Studied versus Tarceva (ZEST) and the Zactima Efficacy trial for NSCLC Patients with History of EGFR-TKI chemo-Resistance (ZEPHYR) trials. Based on a press release by the sponsor of these trials, the PFS time was longer with vandetanib in the ZODIAC and ZEAL trials; the ZEST trial was negative for its primary superiority analysis, but was successful according to a preplanned noninferiority analysis of PFS. Ongoing phase II and III clinical trials will better define the appropriate schedule, the optimal setting of evaluation, and the safety of long-term use of vandetanib.

RESUMEN

INTRODUCTION: Financial toxicity (FT) is a well-recognised problem in oncology. US-based studies have shown that: (a) cancer patients have a 2.7 times risk of bankruptcy; (b) patients who declare bankruptcy have a 79% greater hazard of death; (c) financial burden significantly impairs quality of life (QoL) and (d) reduces compliance and adherence to treatment prescriptions. The aim of the project is to develop and validate a patient-reported-outcome (PRO) measure to assess FT of cancer patients in Italy, where, despite the universal health coverage provided by the National Health Service, FT is an emerging issue. METHODS AND ANALYSIS: Our hypothesis is that a specific FT measure, which considers the relevant sociocultural context and healthcare system, would allow us to understand the main determinants of cancer-related FT in Italy, in order to address and reduce these factors. According to the International Society for Pharmaco-economics and Outcomes Research guidelines on PROs, the project will include the following steps: (1) concept elicitation (from focus groups with patients and caregivers; literature; oncologists; nurses) and analysis, creating a coding library; (2) item generation (using a format that includes a question and a response on a 4-point Likert scale) and analysis through patients' cognitive interviews of item importance within different coding categories to produce the draft instrument; (3) factor analysis and internal validation (with Cronbach's alpha and test-retest for reliability) to produce the final instrument; (4) external validation with QoL anchors and depression scales. The use of the FT measure in prospective trials is also planned. ETHICS AND DISSEMINATION: The protocol is approved by the ethical committees of all the participating centres. The project will tentatively produce a validated tool by the spring 2021. The project might also represent a model and the basis for future cooperation with other European countries, with different healthcare systems and socioeconomic conditions. TRIAL REGISTRATION NUMBER: NCT03473379.

RESUMEN

The approval, in 2015, of the first poly (adenosine diphosphate-ribose) polymerase inhibitor (PARPi; olaparib, Lynparza) for platinum-sensitive relapsed high-grade ovarian cancer with either germline or somatic BRCA1/2 deleterious mutations is changing the way that BRCA1/2 testing services are offered to patients with ovarian cancer. Ovarian cancer patients are now being referred for BRCA1/2 genetic testing for treatment decisions, in addition to familial risk estimation, and irrespective of a family history of breast or ovarian cancer. Furthermore, testing of tumor samples to identify the estimated 3%-9% of patients with somatic BRCA1/2 mutations who, in addition to germline carriers, could benefit from PARPi therapy is also now being considered. This new testing paradigm poses some challenges, in particular the technical and analytical difficulties of analyzing chemically challenged DNA derived from formalin-fixed, paraffin-embedded specimens. The current manuscript reviews some of these challenges and technical recommendations to consider when undertaking BRCA1/2 testing in tumor tissue samples to detect both germline and somatic BRCA1/2 mutations. Also provided are considerations for incorporating genetic analysis of ovarian tumor samples into the patient pathway and ethical requirements.
