- Lactate secreted by cervical cancer cells modulates macrophage phenotype(2019) STONE, Simone Cardozo; ROSSETTI, Renata Ariza Marques; ALVAREZ, Karla Lucia Fernandez; CARVALHO, Jesus Paula; MARGARIDO, Paulo Francisco Ramos; BARACAT, Edmund Chada; TACLA, Maricy; BOCCARDO, Enrique; YOKOCHI, Kaori; LORENZI, Noely Paula; LEPIQUE, Ana PaulaCervical cancer continues to be a public health problem in developing countries. Previous studies have shown that cervical cancer cells display markers of aerobic glycolysis, indicating that these tumors are likely to secrete lactate. Mostly, lactate is recognized as a molecule capable of suppressing immune responses, through inhibition of T cells, M phi s, and dendritic cells. We and others have previously shown that M phi s are frequent cells infiltrating cervical cancers with the ability to inhibit antitumor immune responses and promote tumor growth through angiogenesis. Here, we have tested the hypothesis that lactate, secreted by cervical cancer cells, can modulate M phi phenotype. First, we showed higher lactate plasma concentrations in patients with increasing cervical lesion grades, with maximum concentration in the plasma of cancer patients, which supported our hypothesis. We then inhibited lactate production in tumor cell spheroids established from cervical cancer derived cell lines, using the lactate dehydrogenase inhibitor, oxamate, prior to co-culture with monocytes. Lactate mediated part of the crosstalk between tumor cells and M phi s, promoting secretion of IL-1, IL-10, IL-6, and up-regulation of hypoxia induced factor-1 expression, and down-regulation of p65-NFB phosphorylation in M phi s. We also showed that M phi s from co-cultures treated with oxamate were better inducers of T cell activation. Of note, experiments performed with inhibition of the monocarboxylate transporters rendered similar results. Our data confirms the hypothesis that lactate, secreted by cervical tumor cells, influences the phenotype of tumor M phi s, promoting a suppressive phenotype.

- Interest In and Practices Related to Gynecologic Oncology among Members of the Brazilian Federation of Associations of Gynecology and Obstetrics(2019) SILVA JUNIOR, Arilto Eleuterio da; CARVALHO, Jesus Paula; DERCHAIN, Sophie Francoise Mauricette; RODRIGUES, Angelica Nogueira; MORETTI, Renato; CANDIDO, Eduardo Batista; REIS, Ricardo dos; SANTIAGOL, Aline Evangelista; SILVA FILHO, Agnaldo Lopes daObjective The present study aims to obtain basic demographic information, the level of interest and of training in gynecology oncology among Brazilian obstetricians and gynecologists (OB-GYNs) to create a professional profile. Methods An online questionnaire was sent to 16,008 gynecologists affiliated to the Brazilian Federation of Associations of Gynecology and Obstetrics (FEBRASGO, in the Portuguese acronym). We considered gynecologists dedicated to gynecologic oncology (OB-GYNs ONCO) those who self-reported that > 50% of their daily practice consists in working with women's cancer care. Results A total of 1,608 (10%) of 16,008 FEBRASGO members responded. The OB-GYNs are concentrated in the southern and southeastern states of Brazil. Gynecologic oncology was considered the 8th greatest area of interest in gynecology among the OB-GYNs. A total of 95 (5.9%) of the OB-GYNs were considered OB-GYNs ONCO. Obstetricians and gynecologists are actively engaged in cancer care: > 60% of them dedicate up to 25% of their daily practice to oncology. The role of the physicians in screening and prevention, diagnosis, in the treatment of precancerous lesions, and in low complexity surgical procedures is notably high. Gynecologists dedicated to gynecologic oncology in Brazil have a heterogeneous, nonstandardized and short training period in gynecologic oncology. These professionals had a more significantly role in performing medium- and high-complexity operations compared with OB-GYNs (65.2% versus 34%, and 47.3% versus 8.4%, respectively). Conclusion The role of OB-GYNs and of OB-GYNs ONCO appears to be complementary. Obstetricians and gynecologists act more often in screening and prevention and in low-complexity surgical procedures, whereas OB-GYNs ONCO are more involved in highly complex cases. Strategies to raise standards in cancer training and to encourage the recognition of gynecologic oncology as a subspecialty should be adopted in Brazil.
- Secondary healing strategy for difficult wound closure in invasive vulvar cancer: a pilot case-control study(2019) DIAS-JR, Altamiro Ribeiro; SOARES-JR, Jose Maria; FARIA, Maria Beatriz Sartor de; GENTA, Maria Luiza Noqueira Dias; CARVALHO, Jesus Paula; BARACAT, Edmund C.OBJECTIVES: Despite the number of surgical advances and innovations in techniques over time, radical vulvectomy frequently results in substantial loss of tissue that cannot be primarily closed without tension, the mobilization of surrounding tissues or even the rotation of myocutaneous flaps. The aim of this study was to evaluate the feasibility of leaving the surgical vulvar open wound for secondary healing in situations where primary closure of the vulvar wound is not possible. METHODS: This case-control pilot study analyzed 16 women with a diagnosis of squamous cell carcinoma of the vulva who first underwent inguinofemoral lymphadenectomy, 6-week sessions of chemotherapy and 25 daily sessions of radiotherapy. Afterward, excision of the vulvar lesion with free margins was performed between January 2011 and July 2017. Twelve patients underwent primary closure of the wound (control), and in 4 patients, the surgical wound was left open for secondary healing by means of a hydrofiber (case). The inclusion criteria were a) FIGO-2009 stage II up to IIIC; b) squamous cell carcinoma; and c) no evidence of pelvic or extrapelvic disease or pelvic nodal involvement. The exclusion criteria were extrapelvic disease or pelvic nodal involvement, another primary cancer, or a poor clinical condition. ClinicalTrials.gov: NCT02067052. RESULTS: The mean age of the patients at the time of the intervention was 62.1. The distribution of the stages was as follows: II, n=6 (37 %); IIIA, n=1 (6%), IIIB, n=1 (6%) and IIIC, n=8 (51%). The mean operative time was 45 minutes. The hospital stay duration was 2 days. Full vulvar healing occurred after an average of 30 days in the control group and after an average of 50 days in the case group. CONCLUSION: A secondary healing strategy may be an option for the treatment of vulvar cancer in situations of non-extensive surgical wounds when primary closure of the wound is not possible.
