Abstract Background: To investigate whether adjuvant chemotherapy was essential for patients with early-stage serous and endometrioid epithelial ovarian cancer，we collected data from the US Surveillance, Epidemiology, and End Results database between 2004 and 2015. All subjects underwent comprehensive staging surgery and their pathological diagnoses were stage IA-IIA, grade 1-2. Ultimately, a total of 2,644 patients were enrolled in the study, among which 1,589 patients received platinum-based chemotherapy. Comparisons of categorical data were done by chi-square tests. Variables with P < 0.05 in univariate analysis were further analyzed using multiple logistic regression. Selection bias from the heterogeneity of demographic and clinical characteristics were avoided by propensity score matching. Cox proportional hazards models were applied to estimate hazard ratios (HR) and 95% confidence intervals (CI), exploring the relationship between variables and 5-year overall survival.Results: After propensity score matching, patients with or without chemotherapy were equal number (n=925). Our results indicated that 65 years of age or older increased the hazard and was related to poor prognostic (HR = 1.486, CI = 1.208- 1.827, P < 0.001). Endometrioid carcinoma was associated with better 5-year overall survival than serous cystadenocarcinoma (HR = 0.697, CI = 0.584-0.833, P < 0.001). Chemotherapy could not prolong 5-year overall survival of early-stage serous and endometrioid ovarian cancer patients (HR = 1.092, CI = 0.954-1.249, P = 0.201).Conclusions: These results demonstrated that adjuvant chemotherapy was unnecessary for patients with early-stage serous and endometrioid ovarian cancer after they underwent comprehensive staging surgery.

Abstract In order to investigate whether adjuvant chemotherapy is essential for patients with early-stage serous and endometrioid epithelial ovarian cancer, the present study collected data from the US Surveillance, Epidemiology and End Results database between 2004 and 2015. All subjects underwent comprehensive staging surgery and were diagnosed as stages IA-IIA, grade 1-2. A total of 2,644 patients were enrolled in the present study, among which 1,589 patients received platinum-based chemotherapy. Comparisons of categorical data were performed via χ2 tests. Variables with P<0.05 in univariate analyses were further analyzed using multiple logistic regression. Selection bias from the heterogeneity of demographic and clinical characteristics was avoided using propensity score matching. Cox proportional hazards models were applied to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), investigating the association between variables and 5-year overall survival. After the propensity score matching, there was an equal number of patients with or without chemotherapy (n=925). The results of the present study indicated that those aged ≥65 years were at an increased risk of ovarian cancer, and the age was associated with poor prognosis (HR, 1.486; CI, 1.208-1.827; P<0.001). Endometrioid carcinoma was associated with improved 5-year overall survival compared with serous cystadenocarcinoma (HR, 0.697; CI, 0.584-0.833; P<0.001). Chemotherapy could not prolong the 5-year overall survival of patients with early-stage serous and endometrioid ovarian cancer (HR, 1.092; CI, 0.954-1.249; P=0.201). These results demonstrated that adjuvant chemotherapy was unnecessary for patients with early-stage serous and endometrioid ovarian cancer after they underwent comprehensive staging surgery.

Background: Adjuvant platinum-based chemotherapy improves survival in women with early-stage epithelial ovarian cancer (EOC). Yet, there is a wide variety in clinical practice. Methods: All patients diagnosed with FIGO I and IIa EOC (2006-2010) in the south of the Netherlands were analyzed. The percentage of patients that received adjuvant chemotherapy was determined as well as the comprehensiveness of staging and outcome. Results: Forty percent (54/135) of the patients with early-stage EOC received adjuvant chemotherapy. Treatment with adjuvant chemotherapy was associated with FIGO stage, clear-cell histology and nonoptimal staging. Optimal staging was achieved in 50%, and nonoptimal staging was associated with advanced age, comorbidity and treatment in a non-referral hospital. Overall, there was no difference in outcome between patients with and without adjuvant chemotherapy. Yet, in grade 3 tumors, adjuvant chemotherapy seems beneficial. Conclusions: Selective treatment of patients with early-stage EOC might reduce adjuvant chemotherapy without compromising outcome.

372 Background: Prior National Cancer Database (NCDB) studies have demonstrated an overall survival (OS) benefit for adjuvant concurrent chemoradiation (CRT) compared to chemotherapy alone. Given the more recent adoption of postoperative chemotherapy followed by concurrent chemoradiation (C+CRT), this NCDB analysis evaluates the clinical outcomes of C+CRT compared to CRT alone or adjuvant chemotherapy alone (C) for resected pancreatic cancer. Methods: The NCDB was queried for primary stage I-II, cT1-3N0-1M0, resected pancreatic adenocarcinoma treated with adjuvant C, CRT, or C+CRT (2004-2015). Patients treated with C+CRT were compared with those treated with C (cohort C) or with CRT (cohort CRT). The primary endpoint was overall survival (OS). Baseline patient, tumor, and treatment characteristics were examined. Kaplan-Meier analysis, multivariable Cox proportional hazards method, forest plot, and propensity score matching were used. Results: Among 5667 patients (n = 3031 for C, n = 1307 for CRT, n = 1329 for C+CRT), median follow-up was 34.7 months, 45.2 months, and 39.7 months for the C, CRT, and C+CRT cohorts, respectively. In the multivariable analysis for all patients, C (HR 1.31, p < 0.001) and CRT (HR 1.24, p < 0.001) were associated with worse mortality compared to C+CRT. Treatment interactions were seen among pathologically node positive disease. C+CRT was favored in 1-3 (HR 0.74, p < 0.001) and 4+ (HR 0.75, p < 0.001) positive lymph node disease when compared to C or CRT alone, but none of the treatment options were significantly favored in node negative disease (HR 0.96, p = 0.67). Using 1:1 propensity score matching, 2152 patients for cohort C and 1774 patients for cohort CRT were matched. C+CRT remained significant for improved OS for both cohort C (median OS 23.3 vs 20.0 months, p < 0.001) and cohort CRT (median OS 23.4 vs 20.8 months, p < 0.001). Conclusions: This NCDB study using propensity score matched analysis demonstrates an OS benefit for C+CRT compared to C or CRT alone following surgical resection of pancreatic cancer. Most of this benefit is in patients with positive lymph nodes.

ObjectivesTo assess the effect of complete surgical staging and adjuvant chemotherapy on survival in stage I, low grade endometrioid ovarian cancer.MethodsThis retrospective study was conducted at two cancer centers from July 2001 to December 2019. Inclusion criteria were all stage I, grade 1 and 2 endometrioid ovarian cancer patients. Patients with mixed histology, concurrent endometrial cancer, neoadjuvant chemotherapy, and patients who did not undergo follow-up at our centers were excluded. Clinical, pathologic, recurrence, and follow-up data were collected. Cox proportional hazard model evaluated predictive factors. Recurrence-free survival and overall survival were calculated using the Kaplan-Meier method.ResultsThere were 131 eligible stage I patients: 83 patients (63.4%) were stage IA, 5 (3.8%) were stage IB, and 43 (32.8%) were stage IC, with 80 patients (61.1%) having grade 1 and 51 (38.9%) patients having grade 2 disease. Complete lymphadenectomy was performed in 34 patients (26.0%), whereas 97 patients (74.0%) had either partial (n=22, 16.8%) or no (n=75, 57.2%) lymphadenectomy. Thirty patients (22.9%) received adjuvant chemotherapy. Median follow-up was 51.5 (95% CI 44.3 to 57.2) months. Five-year recurrence-free survival was 88.0% (95% CI 81.6% to 94.9%) and 5 year overall survival was 95.1% (95% CI 90.5% to 99.9%). In a multivariable analysis, only grade 2 histology had a significantly higher recurrence rate (HR 3.42, 95% CI 1.03 to 11.38; p=0.04). There was no difference in recurrence-free survival (p=0.57) and overall survival (p=0.30) in patients with complete lymphadenectomy. In stage IA/IB, grade 2 there was no benefit of adjuvant chemotherapy (p=0.19), and in stage IA/IB, low grade without complete surgical staging there was no benefit of adjuvant chemotherapy (p=0.16). Twelve patients (9.2%) had recurrence; 3 (25%) were salvageable at recurrence and are alive with no disease.ConclusionsPatients with stage I, low grade endometrioid ovarian cancer have a favorable prognosis, and adjuvant chemotherapy and staging lymphadenectomy did not improve survival.

Salvage Rate

Purpose: The role of adjuvant chemotherapy in early-stage epithelial ovarian cancer (EOC) has been controversial. We have previously reported the cases of patients managed with a policy of observation only. We now present the salvage rate for the patients in that study who experienced relapse. Patients and Methods: One hundred ninety-four patients with stage I EOC presenting between 1980 and 1994 received no adjuvant chemotherapy, but were treated with platinum-based chemotherapy at relapse. We calculated the progression-free survival (PFS) and overall survival (OS) for the whole cohort and the salvage rate for those who experienced relapse. We defined salvage as freedom from relapse for 5 years after platinum treatment. Results: Sixty-one (31%) of 194 patients experienced relapse, and 55 received platinum-based chemotherapy. Twenty-four percent were progression-free at 5 years after this treatment. Clear-cell histology and cyst rupture before the patients’ original surgery were independent prognostic factors for PFS after salvage chemotherapy. The OS for all 194 patients is 72% at 10 years (median follow-up, 8.7 years), with an 80% disease-specific survival (DSS). Conclusion: We have shown that some patients with stage I EOC can be successfully treated with a salvage chemotherapy regimen after a policy of observation only. Interestingly, approximately 30% of stage I patients who die within 10 years do so from causes other than EOC (OS, 72%; DSS, 80%). Our findings need to be taken into consideration when the results from recent randomized trials of adjuvant chemotherapy in this patient population (International Collaborative Ovarian Neoplasm Trial 1/European Organization for Research and Treatment of Cancer Adjuvant Chemotherapy in Ovarian Neoplasm Trial) are being discussed with patients.

4056 Background: Anal Squamous Cell Cancer (ASCC) is a highly curable cancer. Underserved and vulnerable populations are particularly at risk of developing this disease. We aimed to study racial disparities and overall survival (OS) in patients with ASCC who received radiation therapy (RT) or chemo-RT (CRT) using the National Cancer Database. Methods: We identified adult patients with early-stage (stage I-II) ASCC diagnosed between 2004-2016 who underwent RT or CRT. We compared the clinical and treatment characteristics of white and black patients. The chi-square test was used for categorical variables. Kaplan-Meier and Cox regression method performed for survival analyses. We used 1:1 nearest neighbor propensity score matching to eliminate selection bias. Results: A total of 10,014 patients; 90.2% were white and 9.8% were black. White patients were more likely to be female, older age, have higher rate high-school education, private insurance, higher income, and travel a longer distance (all p < .001). Black patients were more likely to be higher comorbidity score and be treated at an academic/research facility. White patients had a higher rate of CRT and significantly better overall survival (OS) as compared to black patients (5-year survival 76% vs. 70%, p < .001) which persisted after propensity score matching (5-year survival 76% vs. 70%, p = .002). This difference continued after adjusting for clinically important factors, including HPV status (unmatched p < .03, matched p = .008). In the patients who received CRT, white patients were associated with improved OS versus black patients (unmatched 77% vs. 71%, p < .001; matched 77% vs. 71%, p = .011), and even after multivariate Cox analysis (unmatched p < .001; matched .014) (Table). Conclusions: White patients had significantly better OS as compared to black patients with early-stage ASCC as well as in the patients who received CRT. White patients were associated with high education level, higher income, and private insurance. The rate of HPV positive was similar among groups. Further investigations are needed to enlighten these disparities and target the increase education of the population at risk. [Table: see text]

Abstract Objective The benefit of adjuvant chemotherapy is still controversial for stage II gastric cancer patients. This study aims to identify prognostic factors to guide individualized treatment for stage II gastric cancer patients. Methods We retrospectively reviewed 1121 stage II gastric cancer patients who underwent D2 radical gastrectomy from 2007 to 2017 in the Sixth Affiliated Hospital of Sun Yat-sen University, FuJian Medical School Affiliated Union Hospital and Sun Yat-sen University Cancer Center. Propensity score matching was used to ensure that the baseline data were balanced between the adjuvant chemotherapy group and surgery-only group. Kaplan–Meier survival and multivariate Cox regression analyses were carried out to identify independent prognostic factors. Results In univariate analysis, after propensity score matching, age, tumor location, tumor size, CEA, T stage and N stage were associated with overall survival (OS). Multivariate analysis illustrated that age ≥ 60 years old, linitis plastica and T4 were independent risk factors for OS, but lower location and adjuvant chemotherapy were protective factors. Conclusion Stage II gastric cancer patients with adverse prognostic factors (age ≥ 60, linitis plastica and T4) have poor prognosis. Adjuvant chemotherapy may be more beneficial for these patients.

654 Background: A curative hepatic or pulmonary metastasectomy for colorectal carcer is a generally accepted procedure. However, the value of noncurative locoregional therapy for unresectable metastatic colorectal carcer was not well defined. Methods: Of 1,174 patients with unresectable colorectal cancer from 2003 to 2014 retrospectively reviewed, 62 patients received curative regional treatment, 290 patients received locoregional therapy, and 822 patients received standard chemotherapy. Propensity score matching was used to adjust the balance of baseline data between locoregional therapy arm and chemotherapy arm. Kaplan-Meier survival analyses were based on data after propensity score matching. Factors possibly influencing survival were evaluated by univariate and subsequently by multivariate analyses. Results: After propensity score matching, 544 patients were included in this study, 272 in locoregional therapy arm and 272 in chemotherapy arm, respectively. Locoregional therapy included metastasectomy, radiofrequency ablation, percutaneous microwave coagulation therapy and radioactive particle implantation. The addition of locoregional therapy to chemotherapy significantly improved the overall survival with median overall survival 38.73 months (95%CI 34.93-42.54 months) in locoregional therapy arm versus 19.8 months (95%CI 18.06-21.54 months) in chemotherapy arm, respectively, p<0.001. 9 factors were associated with overall survival by univariate analysis, which include primary tumor site, initial stage at first diagnosis, pathological grading, target organ of regional treatment, CA199 and LDH at diagnosis of advanced disease, CEA, CA199 and LDH before regional treatment. Furthermore, CEA (>5ng/ml) and LDH (>245U/L) before regional treatment were identified as independent poor prognostic factors by multivariate analysis. Median overall survival according to the presence of 0, 1, or 2 factors was 49.4 months, 35.7 months, and 27 months. Conclusions: Unresectable metastatic colorectal cancer also benefited from locoregional therapy. Two pre-locoregional treatment risk factors could select the patients most likely to benefit from this strategy.

12032 Background: Breast cancer incidence in elderly population over 70 years is anticipated to grow up to 35% by 2030. However, this elderly population is under-represented in the TAILORx (Trial Assigning Individualized Options for Treatment) with less than 5% of the entire study cohort. As the omission of radiation therapy among the elderly with favorable prognosis is a reasonable alternative option, omission of chemotherapy has not been prospectively investigated. To address this knowledge gap, we conducted an observational cohort study to evaluate the omission of chemotherapy in elderly patients with early breast cancer. Methods: The National Cancer Database (NCDB) was queried for patients above the age of 70 diagnosed with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, pT1-2N0 breast cancer who underwent hormone therapy with or without chemotherapy (2010-2015). Kaplan-Meier method and Cox multivariable analysis (MVA) were performed for survival analysis. Propensity score matching in a 1:1 ratio without any replacement was used to address selection bias. Sensitivity analysis was performed on a subgroup of those with a high 21-gene recurrence score (RS) > 25. Results: A total of 12004 patients were identified, including 10802 and 1202 patients with and without adjuvant chemotherapy, respectively. The median follow up was 38.2 months (IQR 22.5-57.2). On univariate analysis, chemotherapy was not associated with improved overall survival (HR 0.96, p = 0.71), ineligible for inclusion in the final MVA model. On interaction analysis, the use of chemotherapy had no interaction with RS (p = 0.46), age (p = 0.08), tumor size (p = 0.23), tumor grade (p = 0.42), and comorbidity score (p = 0.22). On 1030 and 689 matched pairs for all RS and RS > 25, respectively, there was no association of overall survival with chemotherapy (all RS: HR 0.76, p = 0.08; RS > 25: HR 0.74, p = 0.10). Conclusions: For elderly patients with early stage breast cancer, the addition of adjuvant chemotherapy may not be associated with improved survival even in the setting of high RS > 25. Given the toxicity profile of systemic therapy, shared decision making between clinicians and elderly patients is needed to individualize treatment options.
