ObjectiveTo evaluate the performance of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET/CT) radiomic features to predict overall survival (OS) in patients with locally advanced uterine cervical carcinoma.MethodsLongitudinal and retrospective study that evaluated 50 patients with cervical epidermoid carcinoma (clinical stage IB2 to IVA according to FIGO). Segmentation of the 18F-FDG PET/CT tumors was performed using the LIFEx software, generating the radiomic features. We used the Mann–Whitney test to select radiomic features associated with the clinical outcome (death), excluding the features highly correlated with each other with Spearman correlation. Subsequently, ROC curves and a Kaplan–Meier analysis were performed. A p-value < 0.05 were considered significant.ResultsThe median follow-up was 23.5 months and longer than 24 months in all surviving patients. Independent predictors for OS were found–SUVpeak with an AUC of 0.74, sensitivity of 77.8%, and specificity of 72.7% (p = 0.006); and the textural feature gray-level run-length matrix GLRLM_LRLGE, with AUC of 0.74, sensitivity of 72.2%, and specificity of 81.8% (p = 0.005). When we used the derived cut-off points from these ROC curves (12.76 for SUVpeak and 0.001 for GLRLM_LRLGE) in a Kaplan–Meier analysis, we can see two different groups (one with an overall survival probability of approximately 90% and the other with 30%). These biomarkers are independent of FIGO staging.ConclusionBy radiomic 18F-FDG PET/CT data analysis, SUVpeak and GLRLM_LRLGE textural feature presented the best performance to predict OS in patients with cervical cancer undergoing chemo-radiotherapy and brachytherapy.

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 restricted 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 patients with previously-treated, recurrent/metastatic cervical cancer. This study was funded by Agenus Inc.

BACKGROUND Coronavirus disease 2019 (COVID‐19) and cancer are serious public health problems worldwide. However, little is known about the risk factors of in‐hospital mortality among COVID‐19 patients with and without cancer in Brazil. The objective of this study was to evaluate the risk factors of in‐hospital mortality among COVID‐19 patients with and without cancer and to compare mortality according to gender and topography during the year 2020 in Brazil. METHODS This was a secondary data study of hospitalized adult patients with a diagnosis of COVID‐19 by real‐time polymerase chain reaction testing in Brazil. The data were collected from the Influenza Epidemiological Surveillance Information System. RESULTS This study analyzed data from 322,817 patients. The prevalence of cancer in patients with COVID‐19 was 2.3%. COVID‐19 patients with neurological diseases and cancer had the most lethal comorbidities in both sexes. COVID‐19 patients with cancer were more likely to be older (median age, 67 vs 62 years; P < .001), to have a longer hospital stay (13.1 vs 11.5 days; P < .001), to be admitted to the intensive care unit (45.3% vs 39.6%; P < .001), to receive more invasive mechanical ventilation (27.1% vs 21.9%), and to have a higher risk of death (adjusted odds ratio [aOR], 1.94; 95% confidence interval [CI], 1.83‐2.06; P < .001) than those without cancer. Patients with hematological neoplasia (aOR, 2.85; 95% CI, 2.41‐3.38; P < .001) had a higher risk of mortality than those with solid tumors (aOR, 1.83; 95% CI, 1.72‐1.95; P < .001) in both sexes. CONCLUSIONS Brazilian COVID‐19 patients with cancer have higher disease severity and a higher risk of mortality than those without cancer., Patients with hematological neoplasia (adjusted odds ratio [aOR], 2.85; 95% confidence interval [CI], 2.41‐3.38; P < .001) have a higher risk of mortality than those with solid tumors (aOR, 1.83; 95% CI, 1.72‐1.95; P < .001) in both sexes.

ObjectivesCervical cancer is the fourth most common cancer in women worldwide. Epidemiological and quality of life (QoL) data in patients with cervical cancer from low- and middle-income countries are scarce. We aimed to describe sociodemographic and clinicopathological characteristics and quality of life of patients with cervical cancer at diagnosis in Brazil.MethodsEVITA is a prospective cohort study of newly diagnosed patients with cervical cancer from May 2016 to December 2017, stages I–IVB, from 16 Brazilian sites representing the five Brazilian regions. At baseline, medical evaluation was performed and European Organization for Research and Treatment of Cancer (EORTC) QLQ-CX24/C30 questionnaires were administered.ResultsA total of 631 patients were included. Mean±SD age was 49.3±13.9 years; skin color was non-white in 65.3%, and 68.0% had ≤8 years of formal education. In total, 85.1% of patients had a Pap smear. The main reasons reported by patients for not having a Pap smear were: lack of interest (46.9%), shame or embarrassment (19.7%), lack of knowledge (19.7%), and difficulty with access (9.1%). Most patients were diagnosed with locally advanced or metastatic disease (FIGO clinical stage II–IV in 81.8%– stage II in 35.2%, stage III in 36.1%, and stage IV in 10.5%). Patients with clinical stage III–IV had worse physical functioning and role functioning.ConclusionsCervical cancer in Brazil is usually diagnosed at an advanced stage. Most patients have low formal education and are unemployed. Lack of interest was identified as a main reason for not having a screening test, and limited access was reported as a reason by

Objectives Compare marital status, household income and labor activity at diagnosis and at 1-year follow-up among cervical cancer (CC) patients in Brazil. Methods LACOG 0215 EVITA is a prospective observational study, within 16 Brazilian sites, including 18 years-old, newly diagnosed, stage I to IV invasive CC patients. We present data collected at baseline and at 1-year follow-up regarding demography, histology, stage, marital status, household income and labor activity. Variables were compared using Chi-square test. Results 593 patients were included in this analysis. 75 (12.6%) were diagnosed in stage I, 452 (76.2%) II-III and 66 (11.2%) IV. Mean age at diagnosis was 57.0, 56.4 and 50.5 years respectively. Squamous cell carcinoma was the most frequent histology. 34.2% of stage I, 30.6% of stage II-III and 24.6% of stage IV patients had 9 or more years of education. About 95% patients had a previous pregnancy history. At 1-year follow-up there was a decrease in the proportion of married patients in stage II-III patients only (53.3% to 47.5%; p-value Conclusions CC may impact patients personal and work life long after diagnosis, even in those diagnosed with curable disease. In this cohort, stage II-III CC face more risk of divorce and job losses. Social support following diagnosis and treatment is essential for CC patients.

e18571 Background: cervical cancer (CC) reveals regional and social inequalities and should be understood not only as an oncological indicator, but essentially as an indicator of social vulnerability and health care needs.CC is the second most incident and the most deadly among women from the Northeast’S Brazil and the third most incident in Brazil Although the HPV vaccine coverage and the Pap smear test are available through the Brazilian public health system, the coverage of the target population is low. objective: Verify the conditions of access/use of the health system by women with cervical cancer (CC) and their families. Methods: Cross-sectional study involving cancer patients admitted to IMIP between 2016 and 2019. The variable data were related to the sociodemographic profile, preventive examination, Human Papillomavirus (HPV) and the influence of the diagnosis of CC on the search for preventive and screening measures by women's family members. Results: Out of the 285 participants,between 9-21 years old and 101 between 25-69 years old. Of the patients studied,55,8% lives urban area. It has a higher performance of biopsies in the public sector (59,5%). The sociodemographic analysis highlights the non-white race (78,2%) and only 6,8% with complete high school. The knowledge about performing the Pap smear reached 88,9% and the disinformation about the HPV reached 44,4%.the school was the largest source of information about the HPV vaccine (30,6%). Related to the influence of cancer, 62,2% said that young family members underwent HPV vaccination and 82,2% related their diagnosis to search for preventive in family members over 25 years old. a much higher percentage than vaccination coverage and preventive exam in the study region report that the diagnosis of cancer influenced the decision to vaccinate (42%) and update the pap test (69%). about 30% of patients had never taken the pap test. the early start (15 - 19y) of the pap test was not significant for the periodic performance of the pap test. 46% reported the lack of information about the importance of the exam as a reason for not performing it and 34% reported fear. conclusion :Strengthening educational activities and offering vaccines against HPV and Pap smears in the diagnosis of a case of cervical cancer can be an opportunity to expand the coverage of preventive measures more effectively among people close to the patient and her community, which cannot be missed. The school was an important source of information about the HPV vaccine and should be directly involved in this fight.Reducing an inequality cycle.

e13628 Background: Cervical cancer (CC) is the second most incident and the most deadly among women from the Northeast’S Brazil and RECIFE-Pernambuco and the third most incident in Brazil. The occurrence of CC expresses a reality of inequality and inequity and should be understood not only as an oncological indicator, but essentially as an indicator of social vulnerability and health care needs. Its distribution occurs heterogeneously. Methods: Determine the geolocation of areas of greatest risk of occurrence of SC from the social and health determinants Considering the high incidence and mortality related to cervical cancer between 2006-2015, in the city of Recife, we used the spatialization technique to identify the most vulnerable territories for our intervention in the city of Recife. Results: 3,844 Cervical Cancer notifications AND 276 OBITUATIONS registered in the period 2006-2015 and the number of deaths in the period from 2009 to 2018, as a result, there are five areas of high influence. from spatialization, the heat zone generated by the 47 deaths that occurred in the north of the city of Recife WAS DETERMANED. Regarding the cytopathological supply, the ratio in 2018 was 0.37, being below the state average, which is 0.41. With a deficit of 45,041 screening cytopathological exams in the age group 25-64 years.the III Health Region was identified, based on the analysis of information from the State Health Secretary, which shows to be one of the areas of great social vulnerability, since 63% of the 22 municipalities that make up this health region and its population is in extreme poverty, according to IBGE (2010). Conclusions: The occurrence of deaths and new cases of cervical cancer in the city of Recife occurs geographically unequally and is associated with indicators of social vulnerability. IS IT POSSIBLE to identify a priority region to intensify public actions for prevention and early diagnosis. A challenging scenario has been found and must be actively addressed.

Objective Cervical cancer is a global public health challenge. Since 1999, platin based chemoradiation (CRT) is the standard treatment for those patients with locally advanced disease. However, this population still has a dismal prognosis and, alternatives approaches such as adjuvant chemotherapy are controversial, especially because of increased toxicity. Neoadjuvant chemotherapy (NACT) could be an option for more intensive treatment with manageable toxicity. Methods A phase II, prospective, non-randomized trial was conducted at a reference center in Recife, Brazil. Locally advanced cervical cancer patients (Ib2–IVa) were treated with neoadjuvant cisplatin 35mg/m 2 and gemcitabine 1000mg/m 2 D1 and D8, for 2cycles. Then, they received CRT (50.4Gy) with weekly cisplatin 40mg/m 2 followed by brachytherapy. Response rate (RR) and toxicity were the primary endpoints. Progression-free survival (PFS) and overall survival (OS) were secondary endpoints. Results Between Sep/2013 and Oct/2015, 50 patients were initiated on NACT and CRT. RR was 81% at the end of treatment. Hematological and gastrointestinal toxicity were most common. Grade 3/4 toxicity was 20% during NACT and 44% during CRT. Late adverse events were present in 20% of patients. PFS at 1 and 3-years were 73.4% (IC 58.7–83.6) and 53.9% (IC 36.9–68.3), respectively; and, OS at 1 and 3-years were 93.9% (IC 82.4–98.0) and 71.3% (IC 53.3–83.3), respectively. Conclusion In our hands NACT in locally advanced cervical cancer patients did not show a meaningful improvement in ORR. Nevertheless, we believe it should be further explored in prospective trials.

The involvement of the leptomeninges by metastatic tumors can be observed in solid tumors, in which case it is termed meningeal carcinomatosis (MC), and in lymphoproliferative malignant disease. It is more common in breast and lung cancer, as well as melanoma, with adenocarcinoma being the most frequent histological type. MC is usually a late event, with disseminated and progressive disease already present and, it is characterized by multifocal neurological signs and symptoms. Diagnosis is based on the evaluation of clinical presentation, cerebrospinal fluid and neuroimaging studies. The better systemic disease control is observed with new therapeutic agents, and the development of neuroimaging methods is responsible for the increasing incidence of such metastatic evolution. Intrathecal chemotherapy is generally the treatment of choice, although frequently palliative. Prognosis is guarded, although a higher performance status may indicate a subgroup of patients with a more favorable outcome. O acometimento leptomeníngeo por metástases tumorais pode ocorrer em tumores sólidos, sendo chamado de carcinomatose meníngea (CM), e também em doenças linfoproliferativas. Tumores de mama, pulmão e melanoma são os principais responsáveis pelos casos, e adenocarcinoma é a histologia mais frequentemente encontrada. A CM é um evento tardio na evolução da doença e caracteriza-se por sinais e sintomas neurológicos multifocais. O diagnóstico se faz pela avaliação conjunta do quadro clínico, neuroimagem e estudo do líquido cefalorraquidiano. O maior controle da doença sistêmica obtido com as novas modalidades terapêuticas e a baixa penetração de drogas no sistema nervoso central, aliados ao desenvolvimento nos métodos de neuroimagem observado nas últimas décadas, são fatores que respondem por um aumento na incidência desta apresentação. A quimioterapia intratecal é o tratamento de escolha, porém, frequentemente paliativo. O prognóstico é reservado, sendo que o melhor performance status pode selecionar um subgrupo de pacientes com melhor evolução.

Meningeal carcinomatosis (MC) occurs in up to 5% of breast cancer patients. Few studies have evaluated prognostic markers in breast cancer patients with MC. Our aim was to describe the treatment of breast cancer patients with MC, and identify prognostic factors related to survival. Sixty breast cancer patients that had a diagnosis of MC between January 2003 and December 2009 were included. The median age was 46 years (range 27-76). Most patients had invasive ductal carcinoma (78.3%) and high histological/nuclear grade (61.7/53.3%). Estrogen and progesterone receptors were positive in 51.7 and 43.3% of patients, respectively, and 15% were HER-2-positive. Symptoms at presentation were headache, cranial nerve dysfunction, seizures, and intracranial hypertension signals. Diagnosis was made by CSF cytology in 66.7% of cases and by MRI in 71.7%. Intrathecal (IT) chemotherapy was used in 68.3% of patients, and 21.6% received a new systemic treatment (chemo- or hormone therapy). Median survival was 3.3 months (range 0.03-90.4). There was no survival difference according to age, nuclear grade, hormonal and HER-2 status, CSF features, sites of metastasis, systemic and IT chemotherapy, or radiotherapy. However, histological grade and performance status had a significant impact on survival in the multivariate analysis. Only four papers have addressed prognostic factors in breast cancer patients with MC in the last two decades. The results of those reports are discussed here. High histological grade and poor performance status seem to impact survival of breast cancer patients with MC. Prospective studies are necessary to clarify the role of IT and systemic treatment in the treatment of those patients.

ObjectiveCervical cancer is a public health problem. A large proportion of patients have locally advanced (LA) disease at presentation and for this group, neoadjuvant chemotherapy (NACT) has an undefined role in the era of chemoradiotherapy. In countries with restricted access to radiotherapy, NACT may precipitate patients’ access to an effective treatment approach. We carried out a systematic review to evaluate available data about NACT followed by chemoradiation.MethodsStudies evaluated the use of NACT followed by chemoradiotherapy. Search strategy was performed in MEDLINE, LILACS, and Cochrane Library from 2003 to 2013. Conference proceedings of American Society of Clinical Oncology annual meeting, International Journal of Gynecological Cancer Society biennial meeting, and European Society of Gynecological Oncology biennial meeting were also reviewed. Key words used were “cervical uterine cancer,” “cervical uterine neoplasm,” “neoadjuvant therapy,” “neoadjuvant treatment,” and “locally advanced.” Data collected included author information, year of publication, study design, number of participants, eligibility criteria, treatment, response rate (RR), disease-free survival, overall survival, and toxicities.ResultsInitial searches retrieved 7670 references. There were 7 eligible trials. Only 2 studies were published and a total of 323 participants were recruited. Patients with LA disease were eligible in most of them. Neoadjuvant chemotherapy consisted of paclitaxel combined with a platinum compound. Compliance was more than 90% in published trials. Response rate to NACT ranged from 67.8% to 70%. Major toxicity was hematological. Survival was evaluated in different points in time. Overall survival was up to 93% in 2 years, and in a poor prognostic group, 81% of patients were alive after 22 months. However, we must interpret these results with caution because of data limitation.ConclusionsOur result raises the possibility of NACT as an alternative upfront treatment for these patients with a small risk of disease progression. In countries where radiotherapy network is limited, randomized clinical trials should clarify its role.

CONTEXT: Non-small cell lung cancer (NSCLC) progresses to distant metastases in most cases. The most frequent sites for distant metastases are the bones, central nervous system, adrenal glands and liver. Dissemination to the skin, myocardium, thyroid gland and intestine may occur, but is rare. CASE REPORT: We describe a case of squamous cell carcinoma in the lungs, with metastases in the colon and thyroid, in a 66-year-old female patient. The lesion was unresectable and chemotherapy was started. The patient evolved with intestinal subocclusion, and colonoscopy showed the presence of a polyp. Biopsy and immunohistochemical analysis on the polyp showed that it was compatible with squamous cell carcinoma of pulmonary origin. At a follow-up consultation, the patient presented a thyroid nodule. A aspiration biopsy and cellblock immunohistochemistry confirmed the squamous cell carcinoma of pulmonary origin. After third-line chemotherapy, the patient progressed with acute obstructive abdomen due to a retroperitoneal mass. She underwent exploratory laparotomy and died due to surgical complications. Metastases to the thyroid and colon are rarely reported in cases of epidermoid carcinoma of the lungs. Gastrointestinal involvement in pulmonary metastases may affect the stomach, small intestine and colon, and cases of bleeding and perforation have already been reported. Although richly vascularized, the thyroid is an infrequent site for metastases. Such sites reflect poor prognoses for the clinical evolution. We did not find any previous reports in the literature, on lung cancer with metastases concomitantly in the colon and thyroid, in a single patient.

There are few data that show pathologic complete response (pCR) to imatinib treatment in gastrointestinal stromal tumors (GISTs). We describe a case of a patient with pCR of a pelvic, locally advanced, high-risk GIST who was treated with neoadjuvant imatinib and ultimately underwent a conservative procedure. A 48-year-old male presented with a pelvic mass 10 cm in diameter. Biopsy revealed a gastrointestinal stromal tumor of rectal origin. Although it was considered initially resectable, an extensive procedure would have been necessary for complete resection. Treatment with imatinib was initiated, resulting in partial response. The patient remained on imatinib for over 15 months, maintaining stable disease. Radical prostatectomy with anal sphincter preservation was performed. Pathological report revealed no viable neoplastic cells. The use of imatinib was held for 6 months after the surgery. At a follow-up 15 months after surgery, the patient had no evidence of disease. Our report may help to guide future studies of neoadjuvant imatinib for large pelvic or rectum GISTs that are initially considered unresectable.
