    A phase II trial with anti-Lewis-Y monoclonal antibody (hu3S193) for the treatment of platinum resistant/refractory ovarian, fallopian tube and primary peritoneal carcinoma
    (2015) SMALETZ, Oren; DIZ, Maria D. P. E.; CARMO, Claudio C. do; SABBAGA, Jorge; CUNHA-JUNIOR, Geraldo F.; AZEVEDO, Sergio J.; MALUF, Fernando C.; BARRIOS, Carlos H.; COSTA, Ronaldo L.; FONTANA, Ana G.; MADRIGAL, Vivian; WAINSTEIN, Alberto J.; YEDA, Fernanda P.; ALVES, Venancio A.; MORO, Ana M.; BLASBALG, Roberto; SCOTT, Andrew M.; HOFFMAN, Eric W.
    Objectives. The primary objective was to evaluate the clinical efficacy of hu3S193, a humanized monoclonal antibody against the Lewis-Y antigen, in patients with platinum resistant/refractory ovarian, fallopian tube and primary peritoneal carcinoma. Secondary objectives were safety and pharmacokinetics. In addition, we sought to determine the potential interaction of clinical benefit and patient characteristics. Methods. This two-stage, multicenter, single arm, phase II trial enrolled eligible patients to receive hu3S193 weekly at a dose of 20 mg/m(2) intravenously for 8 weeks (1 cycle) to a maximum of 3 cycles. Efficacy was measured as clinical benefit rate (objective response or stable disease for at least 24 weeks). Results. 26 of 31 patients were eligible for efficacy analysis. No complete/partial responses were observed. Six patients had stable disease for 24+ weeks [clinical benefit rate 23% (95% CI = 9.77%-46.71%)]. Median PFS was 8.4 weeks (95% CI = 6.0 to 16.1). Median PFS differed between patients with no ascites and no visceral disease and patients with ascites and/or visceral disease [16.1 vs. 8.1 weeks (p = 0.0058)]. The most commonly reported treatment-related adverse events were fatigue (19.3%) and nausea (16.2%). Allergic reactions occurred in 6 patients (5 with Grade 1/2; 1 with Grade 3). Conclusions. Hu3S193 lacked sufficient activity in the first stage of the study to open enrollment to the second stage. However, based on the longer PFS in patients with no ascites and no visceral disease, consolidation strategies in platinum sensitive disease are currently being tested. (C) 2015 Elsevier Inc.

    Economic Modelling of Screen-and-Treat Strategies for Brazilian Women at Risk of Hereditary Breast and Ovarian Cancer
    (2021) CORREA-GALENDI, Julia Simoes; DIZ, Maria del Pilar Estevez; STOCK, Stephanie; MUELLER, Dirk
    Background Clinical evidence supports the use of genetic counselling andBRCA1/2testing for women at risk for hereditary breast and ovarian cancer. Currently, screen-and-treat strategies are not reimbursed in the Brazilian Unified Healthcare System (SUS). The aim of this modelling study was to evaluate the cost effectiveness of a gene-based screen-and-treat strategy forBRCA1/2in women with a high familial risk followed by preventive interventions compared with no screening. Methods Adopting the SUS perspective, a Markov model with a lifelong time horizon was developed for a cohort of healthy women aged 30 years that fulfilled the criteria forBRCA1/2testing according to the National Comprehensive Cancer Network (NCCN) guideline. For women who tested positive, preventive options included intensified surveillance, risk-reducing bilateral mastectomy and bilateral salpingo-oophorectomy. The Markov model comprised the health states 'well', 'breast cancer', 'death' and two post-cancer states. Outcomes were the incremental costs per quality-adjusted life-year (QALY) and the incremental costs per life-year gained (LYG). Data were mainly obtained by a literature review. Deterministic and probabilistic sensitivity analyses were performed to assess the robustness of the results. Results In the base case, the screen-and-treat strategy resulted in additional costs of 3515 Brazilian reais (R$) (US$1698) and a gain of 0.145 QALYs, compared with no screening. The incremental cost-effectiveness ratio (ICER) was R$24,263 (US$21,724) per QALY and R$27,258 (US$24,405) per LYG. Applying deterministic sensitivity analyses, the ICER was most sensitive to the probability of a positive test result and the discount rate. In the probabilistic sensitivity analysis, a willingness to pay of R$25,000 per QALY gained for the screen-and-treat strategy resulted in a probability of cost effectiveness of 80%. Conclusion Although there is no rigorous cost-effectiveness threshold in Brazil, the result of this cost-effectiveness analysis may support the inclusion ofBRCA1/2testing for women at high-risk of cancer in the SUS. The ICER calculated for the provision of genetic testing forBRCA1/2approximates the cost-effectiveness threshold proposed by the World Health Organization (WHO) for low- and middle-income countries.

    Expression of ERCC1 protein (excision repair cross complementing group 1) in patients with invasive carcinoma of the uterine cervix (CC) undergoing definitive chemoradiation (CR)
    (2012) CAIRES, Inacelli Queiroz de Souza; CAIRES-LIMA, Rafael; COLOMBO, Renata; RAMOS, Clarissa C. A.; MACHADO, Karime Kalil; SIQUEIRA, Sheila Aparecida Coelho; CARVALHO, Heloisa de Andrade; FUKUSHIMA, Julia Tizue; ADRA, Thais Rodrigues; HOFF, Paulo M.; ESTEVEZ-DIZ, Maria Del Pilar
    Background: CC is the leading cause of cancer death among women in developing countries. ERCC1 protein participates in DNA repair through the nucleotide excision repair pathway, involved in resistance to platinum-based chemotherapy. Its value as a predictive marker of tumor response to treatment, progression or death is still unknown. We evaluated ERCC1 protein expression and clinical variables as a predictive marker of progression-free survival (PFS) and overall survival (OS) in patients (pts) with CC submitted to CR. Methods: Retrospective data analysis of pts with histological diagnosis of CC, treated with CR between 2004-2009. Platinum-based chemotherapy was administered weekly (x6) concurrent to external beam radiotherapy (EBRT) to the pelvis (39.6 – 45.0 Gy), parametrial boost (14.0 – 20.0 Gy) when indicated and high-dose rate brachytherapy (HDR) (28.0 – 30.0 Gy). ERCC1 expression was assessed by immunohistochemistry (IHC). Results: We analyzed 75 pts, median age was 55 years (range 24-76), the performance status (PS) was 0 or 1 at baseline in 50 pts (66%) and 63 had squamous histology (84%). Thirty-two were stage IIB (43%) and 19 were IIIB (25%). Sixty-five patients received cisplatin 40mg/m2/w (87%) and 9, carboplatin AUC2/w (12%), median of 6 cycles (range 2-9). Median RT and HDR doses were 59.4 Gy (range 40.4 to 60.3) and 28.0 Gy (range 14.0 – 37.5), respectively. Thirty-two pts were available by ERCC1 IHC and all expressed the marker. Median PFS and OS were 35.5 (95% CI – 13.8 - 57.6) and 81 (95% CI- 21.2 - 140.8) months, respectively. In multivariate analysis, receiving < 6 chemotherapy cycles and baseline Hb <10.0 were correlated with disease progression and death, HR 0.302; p 0.011 (95% CI- 0.012-0.762) and HR 0.6; p 0.00 (95% CI- 0.474 – 0.760), respectively. PS at baseline did not correlate with PFS or OS, HR 0.985; p 0.614 (95% CI 0.930 – 1.044). Conclusions: In this population, since all pts expressed the protein, ERCC1 expression couldn't discriminate patients who most benefit from CR. Interestingly, a minimum of 6 chemotherapy cycles and a baseline Hb ≥ 10.0 seem to have a prognostic value.

    Carboplatin-based chemoradiotherapy in advanced cervical cancer: an alternative to cisplatin-based regimen?
    (2016) SEBASTIAO, Ana Morais; ROCHA, Lucila Soares da Silva; GIMENEZ, Rodrigo Darouche; BARROS, Laryssa Almeida Borges de; FUKUSHIMA, Julia Tizuko; SILVA, Samantha Cabral Severino da; MIRANDA, Vanessa da Costa; CAIRES, Inacelli Queiros de Souza; FREITAS, Daniela de; ABDO FILHO, Elias; DIZ, Maria Del Pilar Estevez
    Objective: To evaluate the results of treatment with cisplatin or carboplatin concomitant with radiotherapy (RT) in cases of locally advanced cervical cancer (CC). Methods: This study is a retrospective analysis of medical records of 184 patients with cervical cancer stage IIB-IVA who were treated at Instituto do Cancer do Estado de Sao Paulo from May 2008 to December 2012. All patients received complete pelvic region external-beam RT with weekly cisplatin (cis-RT, 40 mg/m(2); n = 159) or carboplatin (carbo-RT, AUC 2; n = 25), followed by high-dose-rate intracavitary brachytherapy (HDR-ICBT). Primary endpoint was progression free survival; secondary endpoints were overall survival and overall response rate, which includes complete and partial responses. Results: Five or more chemotherapy cycles were administered to 87.3% and 84% of the cis-RT- and carbo-RT- treated patients, respectively (p = 0.749). Estimated 3-years progression free survival was 59% in the cis-RT group vs 40% in the carbo-RT group (p = 0.249). Estimated 3-years overall survival was 70% in the cis-RT group vs 68% in the carbo-RT group (p = 0.298). Overall response rate (95.3% cis-RT vs 95.4% carbo-RT; p = 0.911) and grade >= 3 toxic effects (8.5% cis-RT vs 11.8% carbo-RT; p = 0.757) were similar. In multivariate analysis, only the overall response rate was a significant predictor of survival. Conclusions: Patients with advanced cervical cancer who are treated with carbo-RT have similar 3-years overall survival, progression free survival, overall response rate, and toxic effects when compared to cis-RT-treated patients. Carbo-RT may be an alternative treatment in patients that cannot receive cisplatin.

    Everolimus plus anastrozole for female adnexal tumor of probable Wolffian origin (FATWO) with STK11 mutation
    (2021) ESTEVEZ-DIZ, Maria De Pilar; BONADIO, Renata Colombo; CARVALHO, Filomena Marino; CARVALHO, Jesus Paula
    Female adnexal tumor of probable Wolffian origin (FATWO) are a rare type of cancer that originates from Wolffian duct remnants. Due to its rarity, no standard systemic treatment is established for cases of recurrent or metastatic disease. Previous literature reported the use of platinum-based chemotherapy and c-Kit tyrosine kinase inhibitors for FATWO cases with c-Kit positive expression. Currently, however, the broader availability of next-generation sequencing (NGS) tests allows a better molecular characterization of rare cancer such as FATWO and a possibility for the use of personalized, targeted therapy. Previous case series that performed NGS for FATWO patients described the presence of STK11 mutations in a considerable number of cases, representing a potential target in this population. To our knowledge, we describe here the first case report of a patient with FATWO and STK11 mutation exhibiting a considerable and durable response after treatment with an mTOR inhibitor plus endocrine therapy.

    Phase II study of the safety and efficacy of the anti-PD-1 antibody balstilimab in patients with recurrent and/or metastatic cervical cancer
    (2021) O'MALLEY, David M.; OAKNIN, Ana; MONK, Bradley J.; SELLE, Frederic; ROJAS, Carlos; GLADIEFF, Laurence; BERTON, Dominique; LEARY, Alexandra; MOORE, Kathleen N.; ESTEVEZ-DIZ, Maria D. P.; HARDY-BESSARD, Anne-Claire; ALEXANDRE, Jerome; OPPERMAN, Christina P.; AZEVEDO, Carla Rameri A. S. de; RANDALL, Leslie M.; FELIU, Waldo Ortuzar; ANCUKIEWICZ, Marek; RAY-COQUARD, Isabelle
    Objective. This phase II clinical trial evaluated the safety and antitumor activity of balstilimab, an anti-PD-1 antibody, in patients with previously-treated, recurrent/metastatic cervical cancer. Methods. Eligible patients were 18 years or older with recurrent and/or metastatic cervical cancer and who had relapsed after a prior platinum-based treatment regimen for advanced disease. Balstilimab was administered intravenously at 3 mg/kg once every two weeks, for up to 24 months. The primary endpoint was objective response rate (ORR, RECIST v1.1) as assessed by an independent review committee. Results. At data cutoff, 161 women (median age, 53 years [range 25-81]) were enrolled and treated with balstilimab. Of these, 140 had measurable disease at baseline and one prior line of platinum-based therapy in the metastatic, persistent, or recurrent setting; these patients were included in the efficacy analyses. The ORR was 15% (95% CI, 10.0%-21.8%) and included 5 patients with a complete response and 16 with a partial response. The median duration of response was 15.4 months. In patients with PD-L1-positive tumors the ORR was 20%, however patients with PD-L1-negative tumors also responded to balstilimab (ORR, 7.9%). Responses were not re-stricted to tumors of squamous cell histology, and an ORR of 12.5% was seen in the subset of patients with cervical adenocarcinoma. The disease control rate was 49.3% (95% CI, 41.1%-57.5%). Immune-mediated enterocolitis (3.1%) and diarrhea (1.9%) were the most common grade 3 or higher treatment-related adverse events. Conclusion. Balstilimab demonstrated meaningful and durable clinical activity, with manageable safety, in pa-tients with previously-treated, recurrent/metastatic cervical cancer. (c) 2021 The Authors.

    Health Economic Evaluations of Cancer in Brazil: A Systematic Review
    (2018) CAMPOLINA, Alessandro G.; YUBA, Tania Y.; DECIMONI, Tassia C.; LEANDRO, Roseli; DIZ, Maria del Pilar Estevez; NOVAES, Hillegonda M. D.; SOAREZ, Patricia C. de
    Background: A large number of health economic evaluation (HEE) studies have been published in developed countries. However, Brazilian HEE literature in oncology has not been studied. Objective: To investigate whether the scientific literature has provided a set of HEE in oncology capable of supporting decision making in the Brazilian context. Methods: A systematic review was conducted to identify and characterize studies in this field. We searched multiple databases selecting partial and full HEE studies in oncology (1998-2013). Results: Fifty-five articles were reviewed, of these, 33 (60%) were full health economic evaluations. Type of cancers most frequently studied were: breast (38.2%), cervical (14.6%), lung (10.9%) and colorectal (9.1%). Procedures (47.3%) were the technologies most frequently evaluated. In terms of the intended purposes of the technologies, most (63.6%) were treatments. The majority of the incremental cost-effectiveness ratios (ICERs) reported have been below the cost-effectiveness threshold suggested by the World Health Organization (WHO). Conclusions: There has been an increase in the number of HEEs related to cancer in Brazil. These studies may support decision-making processes regarding the coverage of and reimbursement of healthcare technologies for cancer treatment in Brazil.
