e12005 Background: [18F] fluorodeoxyglucose positron emission tomography (18F-FDG–PET) scans are known as an important imaging study with their reflection biological activity in various malignancies. To investigate clinical impact of 18F-FDG–PET in breast cancer, we performed survival analysis with maximum standardized uptake values (SUVmax), and compared SUVmax according to breast cancer subtypes. Methods: We reviewed the medical records of 462 patients with breast cancer who underwent primary surgery between April 2004 and December 2008 at single institute. Patients were classified as 4 subtypes: luminal A, luminal B, HER2 and triple negative. The entire patients were randomly assigned as training set (n=220) and validation set (n=242). Results: High SUVmax vs. low SUVmax group was defined with cut-off points of 4 in a training set.At a median follow-up of 6.03 years, the patients with high SUVmax had a shorter disease-free survival in a validation set (p = 0.018, log-rank test). Using multivariate analysis for disease-free survival in the entire patients, high SUVmax was demonstrated as a poor prognostic factor (hazard ratio 2.34, 95% confidence interval 1.18-4.67). In the comparison among subtypes, mean of SUVmax was higher in triple negative type and HER2 type. Also, high SUVmax was significantly associated with larger tumor size, positive node, high Ki67 (≥14%), ER negative, and high histologic grade, and HER2 positive. Conclusions: In breast cancer, the patients with higher SUVmax showed a shorter disease-free survival. Higher SUVmax found in HER-2 and triple negative type suggests that 18F-FDG PET could reflect molecular signature.

There is substantial risk that prognosis determined with routine clinical staging for cervical cancer may be inaccurate. This is primarily due to understaging due to the lack of detection of nodal disease. This is particularly true for para-aortic nodal metastases. Treatment based on such staging may also be inadequate for the same reason. Positron emission tomography (PET) has been demonstrated to be useful in the staging of cervical cancer and superior to either computed tomography or magnetic resonance imaging in the detection of nodal disease. Our objective was to determine the prognostic value of pretreatment 2-[18F]-fluoro-2-deoxy-D-glucose (FDG) PET scan in women with cervical cancer. We reviewed the records of 56 women with cervical cancer who underwent FDG PET scan prior to treatment. The primary outcome was the effect of abnormal FDG uptake consistent with metastatic nodal disease on 20-month disease-free survival. The pretreatment PET scan demonstrated abnormal FDG uptake in the pelvic nodes alone in 14 (25%) women, in pelvic and para-aortic nodes in 10 (17.9%), and in neither pelvic nor para-aortic nodes in 32 (57.1%). Women with positive pelvic nodes by PET as well as women with positive para-aortic nodes had significantly poorer 20-month disease-free survival compared to women with negative nodes (P= 0.0003 and P= 0.0017, respectively). We conclude that pretreatment FDG PET scan revealing abnormal FDG uptake consistent with nodal disease is a robust predictor of disease recurrence and may alter the therapeutic management of some patients.

e17013 Background: This study aimed to evaluate the role of pretreatment [18F] fluorodeoxyglucose positron emission tomography (18F-FDG-PET) as a predictor of disease-free survival (DFS), and overall survival (OS) in locally advanced nasopharyngeal carcinoma (LANC) patients treated definitively with docetaxel-based induction chemotherapy followed by concurrent chemoradiation (CRT). Methods: After obtaining the institutional review board approval, we conducted a retrospective analysis of LANC patients (T1,N1-3 and T2-T4,anyN disease) treated definitively between January 2007 and December 2011 with induction chemotherapy docetaxel , cisplatin, and 5- flurouracil (TPF) followed by CRT utilizing weekly cisplatin and had pretreatment 18F-FDG-PET. We examined the association between the pretreatment primary tumor maximum standardized uptake value (SUVmax) and the treatment outcomes. The disease-free survival (DFS), and overall survival (OS) were calculated by the Kaplan-Meier method, and the differences were evaluated on logrank test. The prognostic significance was assessed by univariate and multivariate analyses. Results: The study included 38 eligible LANC patients. The 4-year OS and PFS rates were 94.9% and 84.7%, respectively. The median OS and PFS intervals were not reached. On univariate analysis, the 4-years DFS was significantly higher in patients with pretreatment SUVmax ≤ 8 compared to > 8 (92.3% vs 56%, P = 0.017). It was also significantly correlated to pretreatment T stage (P=0.001), N stage (P=0.011) and the treatment response (P < 0.001) and treatment breaks (P< 0.001). On a multivariate analysis, the SUVmax category was the only factor correlated with 4-year DFS (hazard ratio = 13.2, 95% C I 1.27-136.8, P= 0. 030) but not for OS (P = 0.068). Conclusions: This study shows that the pretreatment primary tumor SUVmax is a potential independent prognostic predictor of clinical outcomes in patients with LANC treated definitively with TPF induction chemotherapy followed by CRT. Further randomized controlled clinical III trials are needed to provide clear evidence of this benefit.

IntroductionRecent evidence has shown adverse oncological outcomes when minimally invasive surgery is used in early-stage cervical cancer. The objective of this study was to compare disease-free survival in patients that had undergone radical hysterectomy and pelvic lymphadenectomy, either by laparoscopy or laparotomy.MethodsWe performed a multicenter, retrospective cohort study of patients with cervical cancer stage IA1 with lymph-vascular invasion, IA2, and IB1 (FIGO 2009 classification), between January 1, 2006 to December 31, 2017, at seven cancer centers from six countries. We included squamous, adenocarcinoma, and adenosquamous histologies. We used an inverse probability of treatment weighting based on propensity score to construct a weighted cohort of women, including predictor variables selected a priori with the possibility of confounding the relationship between the surgical approach and survival. We estimated the HR for all-cause mortality after radical hysterectomy with weighted Cox proportional hazard models.ResultsA total of 1379 patients were included in the final analysis, with 681 (49.4%) operated by laparoscopy and 698 (50.6%) by laparotomy. There were no differences regarding the surgical approach in the rates of positive vaginal margins, deep stromal invasion, and lymphovascular space invasion. Median follow-up was 52.1 months (range, 0.8–201.2) in the laparoscopic group and 52.6 months (range, 0.4–166.6) in the laparotomy group. Women who underwent laparoscopic radical hysterectomy had a lower rate of disease-free survival compared with the laparotomy group (4-year rate, 88.7% vs 93.0%; HR for recurrence or death from cervical cancer 1.64; 95% CI 1.09–2.46; P=0.02). In sensitivity analyzes, after adjustment for adjuvant treatment, radical hysterectomy by laparoscopy compared with laparotomy was associated with increased hazards of recurrence or death from cervical cancer (HR 1.7; 95% CI 1.13 to 2.57; P=0.01) and death for any cause (HR 2.14; 95% CI 1.05–4.37; P=0.03).ConclusionIn this retrospective multicenter study, laparoscopy was associated with worse disease-free survival, compared to laparotomy.

IntroductionComprehensive updated information on cervical cancer surgical treatment in Europe is scarce.ObjectiveTo evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database.MethodsThe SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified.ResultsThe mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m2 (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0–84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation.ConclusionsIn this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.

Abstract Background Response of cervical cancer patients to neoadjuvant therapy differs from person to person. It remains unclear whether genetic alterations can predict response to neoadjuvant therapy and disease-free survival in cervical cancer.Methods 62 Chinese patients with stage IB-IIA cervical cancer were included in this study. Pre-treatment tumor tissues were profiled using a targeted next-generation sequencing assay. Genetic alterations were compared with those identified in the Western populations using the TCGA database. Pathological response and disease-free survival (DFS) were evaluated and their correlations with genetic alterations were analyzed.Results Genetic alterations in PIK3CA were prevalent in both Chinese and Caucasian populations. The mutation frequencies of TERT, POLD1, NOS2, and FGFR3 were significantly higher in Chinese patients whereas RPTOR, EGFR, and TP53 were frequently mutated in Caucasian patients. Germline mutations were identified in 13 out of 62 Chinese patients and 57% of them occurred in DNA repair genes, such as BRCA1/2, TP53 and PALB2. High tumor mutation burden (TMB), TP53 polymorphism (rs1042522) and KEAP1 mutations were found to be associated with poor response to neoadjuvant therapy. KEAP1 mutations, PIK3CA-SOX2 co-amplification, TERC amplification and TYMS polymorphism were associated with higher relapse rates of cervical cancer.Conclusion The similarity and difference of mutation landscape of Chinese and Caucasian patients suggested genetic background played a role in shaping the architecture of cervical cancer mutations. The associations of mutation feature of cervical cancer with patient response and tumor recurrence risk provided rationale to further validate and explore potential biomarkers for cervical cancer patients.

Abstract   The treatment of esophageal cancer is in constant evolution. Most of the esophageal cancer receive induction chemoradiation therapy. Surgical delay has been studied but the optimal timing has not been clarified. Through the years, surgical delay has been modified by surgeons in our institutions, going from an average of 6 weeks delay to an average of 10 weeks delay. It is time to ask if this change has a real positive impact on our patient. Methods In this retrospective multi-center study, we combined data from two center in Quebec city that performs oncologic esophagectomy. The surgical delay went from 6 to 10 weeks around 2014. All surgeons changed their practice at that moment. We retrospectively analysed 5 years before and after the change of practice and created two cohorts of patients. Our primary outcome compared complete pathologic response rate. Our secondary outcomes were surgical complications, anastomotic leak, disease free survival and overall survival. Results Thirty-eight patients had surgery under 8 weeks (mean: 6 weeks) after their induction chemoradiation compared to 64 patients that had surgery after 8 weeks (mean: 10 weeks). There was no statistical significant difference between groups for the complete pathologic response (32% vs 25%, p = 0,16). Important complications were similar, with a rate of 24% vs 28% (p = 0,69). Anastomotic leaks were less frequent in the less than 8 weeks group, but no statistical significance was obtained (13% vs 27%, p = 0,14).No difference in the disease-free survival rate and overall survival rate was noted (DFS 40% vs 55% (p = 0,32), OS 38% vs 38% (p = 0,29)). Conclusion The treatment of esophageal cancer is in constant evolution, induction therapy and surgical technics involve over time. Surgical delay has no impact on complete pathologic response, complication and overall survival. There is no advantage to wait longer before surgery.
