e16553 Background: While endometrial cancer may be associated with many comorbid conditions, none have been characterized as changing overall prognosis. The aim of this study was to identify medical conditions or laboratory values, that may serve as prognostic factors in stage III and IV endometrial cancer. Methods: A retrospective chart review identified 112 women with stage III or IV endometrial cancer between years 1993–1998. Information about medical comorbidities and presenting lab values were collected using electronic medical records. Progression free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier survival method and the log rank test. Results: The average age was 64.9 yrs. 79 women (70.5%) had stage III disease and 33 women (29.5%) had stage IV disease. For those with a baseline creatinine <1.2 (n = 91), the PFS and OS were not significantly different from those with a baseline creatinine ≥1.2 (n = 17; p = 0.554 and p = 0.487, respectively). There was a non-significant trend toward worse PFS for the 41 patients with hypertension (HTN) compared to the 62 without (48.0 and 61.2 months, p = 0.191). The overall survival was significantly worse for those with HTN (38.7 months vs. 56.0 months p = 0.046). For those with known coronary artery disease, no significant difference in PFS or OS was found (p = 0.792 and p = 0.312 respectively). Those with diabetes (n = 15) did not have a significantly different PFS compared to those who did not (n = 88; p = 0.728). The OS was worse at 20.1 months for those with diabetes compared to 54.3 months for those without (p = 0.001). Baseline albumin had a significant effect on both PFS and OS. Those with an albumin <3.5 (n = 54) had a PFS of 46.2 months compared to 94.0 months for those with an albumin ≥3.5 (n = 23; p = 0.007), and the OS for those with low albumin was 44.8 months compared to 83.4 months for those with the higher albumin (p = 0.005). Conclusions: These results suggest that past medical history and some baseline laboratory values may be important in considering prognosis. In particular, patients with a history of HTN or diabetes have a worse overall survival. Those with a baseline albumin of <3.5 have a worse PFS and OS. No significant financial relationships to disclose.

6014 Background: Chemoradiation (CRT) with cis or anti-EGFR Ab has been shown to improve survival of patients with stage III-IV HNC. Since Lap, a dual EGFR and HER2 inhibitor, has shown effectiveness with CRT in a pilot non-HPV HNC cohort, the RTOG Foundation launched a phase II trial to test the hypothesis that adding Lap to the RT-cis for frontline therapy of stage III-IV Non-HPV HNC improves progression-free survival (PFS). Methods: Patients with stage III-IV carcinoma of the oropharynx (p16-negative), larynx, and hypopharynx, having Zubrod performance of 0-1, and meeting predefined blood chemistry criteria were enrolled after providing consent. Patients were randomized (1:1) to 70 Gy (6 weeks) + 2 cycles of CDDP (q3 weeks) plus either Lap (1500 mg daily, Arm A) or placebo (Arm B) starting 1 week prior to RT and concurrent with RT and for 3 months post RT. PFS was the primary endpoint. The protocol specified 69 PFS events (142 patients) for the final analysis based on HR = 0.65, 80% power, 1-sided alpha 0.20, and one interim efficacy and futility analysis at 50% information. PFS rates between arms for all randomized patients were compared by 1-sided log-rank test (1-sided alpha 0.1803). Overall survival (OS) was a secondary endpoint. Results: From 10/’12 to 04/’17, 142 patients were enrolled, of whom 127 were randomized, 63 to Arm A and 64 to Arm B. Arms A vs B, respectively, were similar in baseline patient characteristics, radiation delivery, completing ≥ 70 Gy (85.7% vs. 82.8%) and cisplatin delivery, completing 200 (±5%) mg/m2 (65.1% vs 70.3%), but dissimilar in Lap/placebo delivery (median dose, 87000 mg vs. 125250 mg). Median follow-up was 4.1 years for surviving patients. The final analysis suggests no improvement in PFS of adding Lap to CRT (HR [A/B]: 0.91, 95% confidence interval CI 0.56-1.46; P= 0.34; 2-year rates: 50.6%, CI 37.5-63.7% vs. 56.2% CI 43.0-69.4%), or in OS (HR: 1.06, CI 0.61-1.86; P = 0.58; 2-year rates: 71.8% CI 60.1-83.5% vs. 76% CI 64.5-87.4%), death within 30 days of therapy (3.3% vs. 3.4%), and overall treatment-related grade 3-5 adverse event rate (86.7% vs. 84.7%). Grade 3-4 mucositis rates on Arm A and Arm B were 21.7% vs. 23.7%, all grade dysphagia and rash rates were 43.3% vs. 59.3%, and 13.3% vs. 6.8%, respectively. Conclusions: The addition of Lap to the radiation-cisplatin platform did not improve progression-free or overall survival in unselected non-HPV HN. Thus, dual EGFR, HER-2 inhibition does not appear to enhance the effects of chemoradiation. Although we showed that accrual to a non-HPV HN specific trial is feasible, new strategies must be investigated to improve the outcome for this poor prognosis HN population.

Abstract Purpose: The GHSG HD9 trial had established BEACOPP escalated (BE) as new standard of care for advanced-stage HL patients by showing significant superiority in terms of failure-free survival (FFTF) and overall survival (OS) over COPP/ABVD and BEACOPP baseline (BB) (each 8 cycles). The successor study, HD12, evaluated a possible reduction in toxicity by comparing 8 cycles of BE with 4 cycles BE followed by 4 cycles BB. The second question in this trial related to the need of additional radiotherapy (RT) to initial bulk and residual disease. Patients and methods: HL patients in stage IIB with large mediastinal mass and/or E-lesions or stage III/IV were randomised according to a 2×2-factorial design between: 8BE + RT, 8BE no RT, 4BE+4BB + RT, 4BE+4BB no RT. Reviewing CT-images before and after chemotherapy treatment, fields for RT were centrally planned by a multidisciplinary diagnostic panel blinded for the randomisation arm. Primary endpoint of the trial was FFTF. Between 9/1999 and 1/2003, a total of 1,670 patients aged 16–65 were randomized. For this final analysis at a median follow up of 78 months, 99 patients were excluded (42 HL not confirmed, 20 revision of stage, 20 no study treatment or documentation, 17 others) resulting in 1,571 eligible patients. Results: Patient characteristics in the 4 groups were comparable with 49% of patients in stage III, 35% in stage IV, 68% reporting B-symptoms and 28% having a large mediastinal tumor. An IPS of 3 or greater was reported for 38% of patients, predominant histology was nodular sclerosis with 57% of cases. Treatment-related toxicity of WHO grade III/IV was observed in 97% of patients. Most prominent differences between pooled chemotherapy arms were anemia (65% 8BE vs 51% 4BE+4BB) and thrombopenia (65% vs 51%). Treatment outcome: complete remission 92.4%; early progression 2.2%; progression/relapse 7.8% (6.6% and 8.5%). A total of 156 (9.9%) deaths (72 vs 84) have been observed (22 vs 32 acute or salvage treatment toxicity; 15 vs 24 HL; 22 vs 13 secondary neoplasia). Most treatment related deaths occurred in the &gt;60 years age group, the first 4 cycles and the IPS&gt; 3 RF groups. Secondary neoplasias were observed in 77 patients (4.9%): AML/MDS 1.5% vs 1.4%, NHL 1.4% vs 0.6% and solid tumors/others 2.5% vs 2.3%. At 5 years, OS was 91%, FFTF 85.5% and progression free survival (PFS) 86.2% (Kaplan- Meier estimates). Estimates for the difference at 5 years are 1.8% for OS, 2.3% for FFTF and 2.7% for PFS favoring BE. However, there was no statistical difference between 8x BE and 4BE+4BB in all outcome parameters (p&gt;0.19, log rank test). There is also no significant difference between the RT or no-RT arms in this study with the caveat that a number of high-risk patients receiving RT based on the blinded panel decision. Conclusion: The adoption of 4BE+4BB as a new standard in the future GHSG studies will depend on a refined analysis of the total data set and will be presented.

e16546 Background: Carboplatin sensitivity in drug resistance assays has been shown to be an independent predictor of longer progression free interval with conflicting results in overall survival. We evaluated in vitro drug resistance for carboplatin and paclitaxel combination and its correlation with progression free survival (PFS) and overall survival (OS). Methods: From April 1, 2006 to December 12, 2011, in vitro drug resistance assays were sent after cytoreductive surgery for primary epithelial ovarian cancer. Patients were analyzed according to drug resistance scoring system of low drug resistance (S), intermediate drug resistance (I), and extreme drug resistance (R). Retrospective chart review was performed to evaluate PFS and OS. The Kaplan Meier product limit method was used to estimate OS and PFS. Survival curves were compared between groups using the log rank test. Results: From a total of 142 patients: 57 were S, 52 I, and 33 R; 77% were responsive (S+I) to carboplatin and paclitaxel combination. At median follow-up of 18 months, PFS and OS rates were 58.1 and 91.3% respectively for S, 66.1 and 78.7% for I, and 43.2% and 84.3% for R. At 36 months, the PFS and OS rates were 52.3 and 61.1% for S, 51.3 and 55.3% for I and 39.3% and 48.7% for R. There was OS advantage between the S and I compared to R. There were no significant differences in PFS curves (p<0.281) or OS curves (p<0.46). Conclusions: Although sensitivity to carboplatin/ paclitaxel resulted in longer OS, the results were not statistically significant. Our cohorts were small and we may not have had the power to capture statistical significance. A larger multicenter analysis would be needed to further evaluate this finding. In addition, one of the regimens our patients received on relapse was bevacizumab which was not evaluated in the in vitro assay sensitivity assay. Bevacizumab has also been included in first line treatment in combination with platinum/ taxane regimen. Future analysis of in vitro assays may need to include biologics.

8511 Background: Dramatic responses to MET inhibitors have been reported in patients with NSCLC harboring activating mutations that cause MET exon 14 ( METdel14) skipping. We conducted a multicenter retrospective analysis of pts with METdel14 NSCLC to determine if treatment with MET inhibitors impacts survival. Methods: We collected clinicopathologic data on pts with METdel14 NSCLC. Event-time distributions were estimated using Kaplan-Meier and compared with the log-rank test. Multivariable Cox models were fitted to estimate hazard ratios. Results: Of the 148 pts with METdel14 mutant NSCLC, the median age was 72 (range 43-88); 57% were women, and 41% were never smokers. The most common histologies were adenocarcinoma (77%) and pulmonary sarcomatoid carcinoma (14%). Overlap with oncogenic driver mutations in other genes was rare. At the time of diagnosis, 70% of pts had stage I-III disease, and 30% had stage IV disease. Of the 34 pts with metastastic disease who never received a MET inhibitor, the median overall survival (mOS) was 8.1 months. In this cohort, cancers that also had concurrent MET amplification had a trend toward worse survival compared to cancers without MET amplification (5.2 months vs 10.5 months, P = 0.06). Of the 27 pts with metastatic disease who received at least one MET inhibitor (including crizotinib, glesatinib, capmatinib, and ABBV-399), the mOS was 24.6 months. A model adjusting for receipt of a MET inhibitor as first- or second-line therapy as a time-dependent covariate demonstrated that treatment with a MET inhibitor was associated with a significant prolongation in survival (HR 0.11, 95% CI 0.01-0.92, P = 0.04). Among 22 patients treated with crizotinib, the median progression-free survival (PFS) was 7.36 months. Conclusions: Forpts with METdel14 NSCLC, treatment with a MET inhibitor is associated with an improvement in overall survival. The prognosis of pts who never received treatment with a MET inhibitor appears to be poor, particularly among METdel14 cancers with concurrent MET amplification.

488 Background: Progression-free survival (PFS) is often used as a primary endpoint in oncology clinical trials as a surrogate for overall survival. Traditionally, the Response Evaluation Criteria in Solid Tumors (RECIST) have defined disease progression as a significant increase in the size of tumor lesions and the development of new lesions. However, some patients starting immunotherapy have shown initial increased size of tumor lesions followed by tumor regression, due to the unique mechanism of action of immunotherapies. This initial “pseudo-progression” could be classified inaccurately as disease progression, as evidenced by benefit from the treatment beyond progression approach ( JAMA Oncol 2016). The phase III CheckMate 025 trial of nivolumab versus everolimus in patients with advanced renal cell carcinoma allowed treatment beyond progression if there was investigator-assessed clinical benefit and tolerability. The purpose of our study was to test if treatment duration for an immunotherapy was different from RECIST-defined PFS, and as such, could potentially explain the apparent lack of correlation between RECIST progression and overall survival shown in CheckMate 025. Methods: Using 1-year data from CheckMate 025, Kaplan–Meier methodology was used to estimate the median duration of PFS and time to treatment discontinuation (TTD). Stratified log-rank test was used to assess the difference in treatments. Results: For all patients, the median PFS with nivolumab was 4.6 months (95% CI, 3.7–5.4 months) and median TTD was 6.2 months (95% CI, 5.6–7.7 months). For everolimus, the median PFS was 4.4 months (95% CI, 3.7–5.5 months) and median TTD was 3.9 months (95% CI, 3.7–4.6 months). Conclusions: Patients in CheckMate 025 had significantly longer survival with nivolumab than with everolimus, but with similar PFS. Our analysis demonstrated that while PFS was similar to TTD with everolimus, there was a significant difference between the 2 measures for nivolumab, suggesting that RECIST-defined PFS may not be the proper endpoint to define progression for immunotherapies. Further evaluation of the association of TTD and other immune-related progression endpoints with overall survival is warranted. Clinical trial information: NCT01668784.

2002 Background: This study sought to update the predictive significance of the three WHO-defined molecular glioma subgroups ( IDHwt, IDHmt/noncodel, and IDHmt/codel) in the subset of specimens available for analysis in NRG Oncology/RTOG 9802, a phase III trial of high-risk low-grade gliomas (LGGs) treated with radiation (RT) with and without PCV after biopsy/surgical resection. Notably, this is the first phase III study to evaluate the predictive value of the WHO subgroups in LGGs using prospectively-collected, well-annotated long-term overall survival data, in a post-hoc analysis. Methods: IDH1/2 mutation status was determined by immunohistochemistry and/or next-generation sequencing. 1p/19q status was determined by Oncoscan and/or 450K methylation data. Treatment effects on overall survival (OS) and progression-free survival (PFS) by marker status were determined by the Cox proportional hazard model and tested using the log-rank test in a secondary and exploratory analysis. Results: Of all the randomized eligible high-risk G2 patients (N = 251) in NRG Oncology/RTOG 9802, 106(42%) patients had tissue available with sufficient quality DNA for profiling. Of these, 80(75%) were IDHmut; 43(41%) were IDHmut/non-co-deleted, 37(35%) were IDHmut/co-deleted, and 26(24%) were IDHwt. Upon univariate analyses, no significant difference in either PFS or OS was observed with the addition of PCV in the IDHwt subgroup. Both the IDHmut/non-co-deleted and IDHmut/co-deleted subgroups were significantly correlated with longer PFS (HR = 0.32; p = 0.003; HR = 0.13; p < 0.001) and OS (HR = 0.38; p = 0.013; HR = 0.21; p = 0.029) in the RT plus PCV arm, respectively. Conclusions: Our analyses suggest that both IDHmut/non-co-deleted and IDHmut/co-deleted subgroups received benefit from treatment with PCV although sample size is limited and analyses are post-hoc. Our results also support the notion that IDHwt high-risk LGG patients do not benefit from the addition of PCV to RT. Funding: U10CA180868, U10CA180822, and U24CA196067.

ObjectiveEndometrial cancer often coexists with uterine adenomyosis. However, little is known about the clinical characteristics of these cases. Thus, cases of endometrial cancer occurring with and without uterine adenomyosis were compared, and the influences of uterine adenomyosis on the clinical progress of endometrial cancer were examined.Materials and MethodsOf endometrial cancer patients who underwent hysterectomies in our facility from 2002 to 2011, we included only endometrioid adenocarcinoma patients in our study. The patients were divided into 2 groups, adenomyosis group and nonadenomyosis group, according to the presence/absence of uterine adenomyosis. Patient characteristics, stage, histopathological grade, muscle invasion, recurrence, and mortality were retrospectively compared and examined.ResultsThere were 362 cases of endometrioid adenocarcinoma of the uterine body, of which 121 (33.4%) and 241 cases (66.6%) were in the adenomyosis and nonadenomyosis group, respectively. There were no significant differences with respect to the disease stages or ratios of the histopathological grade between the 2 groups. In the adenomyosis group/nonadenomyosis group, 5-year progression-free survival for International Federation of Gynecology and Obstetrics (FIGO) stages I and II was 89.9%/93.7% and that for stages III and IV was 70.6%/62.0%; the 5-year overall survival was 100%/95.9% for FIGO stages I and II, and 88.0%/73.5% for stages III and IV. There were no significant between-group differences for either progression-free survival or overall survival. When limiting the results to only FIGO stage I endometrioid adenocarcinoma, despite no grade variance between the 2 groups, a significant difference was observed in the ratios of outer-half muscle invasion between the adenomyosis and nonadenomyosis groups (19.5% [17/87] vs 10.1% [16/158], P < 0.05); however, the prognosis was similar in the 2 groups.ConclusionsUterine adenomyosis is associated with deep myometrial invasion in stage I endometrioid adenocarcinoma; however, it did not affect the recurrence or mortality rates.

BackgroundPIK3CA is a high-frequency mutation gene in colorectal cancer, while its prognostic value remains unclear. This study evaluated the mutation tendency, spectrum, prognosis power and predictive power in cetuximab treatment of PIK3CA in Chinese CRC cohort.MethodsThe PIK3CA exon 9 and 20 status of 5763 CRC patients was detected with Sanger sequencing and a high-resolution melting test. Clinicopathological characteristics of 5733 patients were analyzed. Kaplan-Meier method and nomogram were used to evaluate the overall survival curve and disease recurrence, respectively.ResultsFifty-eight types of mutations in 13.4% (771/5733) of the patients were detected. From 2014 to 2018, the mutation rate of PIK3CA increased from 11.0% to 13.5%. At stage IV, exon 20 mutated patients suffered shorter overall survival time than wild-type patients (multivariate COX regression analysis, HR = 2.72, 95% CIs = 1.47-5.09; p-value = 0.012). At stage III, PIK3CA mutated patients were more likely to relapse (multivariate Logistic regression analysis, exon 9: OR = 2.54, 95% CI = 1.34-4.73, p = 0.003; exon 20: OR = 3.89, 95% CI = 1.66-9.10, p = 0.002). The concordance index of the nomogram for predicting the recurrence risk of stage III patients was 0.685. After cetuximab treatment, the median PFS of PIK3CA exon 9 wild-type patients (n = 9) and mutant patients (n = 5) did not reach a significant difference (3.6 months vs. 2.3 months, Log-rank test, p-value = 0.513).ConclusionsWe found that PIK3CA mutation was an adverse predictive marker for the overall survival of stage IV patients and recurrence of stage III patients, respectively. Further more, we suggested that PIK3CA exon 9 mutations are not negative predictors of cetuximab treatment in KRAS, NRAS, and BRAF wild-type mCRC patients.

e18101 Background: To determine if the sequencing of chemotherapy with external beam radiotherapy (EBRT) in the adjuvant setting for FIGO stage III endometrial cancer impacts 2-year progression free survival (PFS). Methods: As part of our Gynecologic Oncology Multidisciplinary Group's initiative to establish an institutional guideline for the adjuvant treatment of Stage III endometrial cancer, we reviewed 144 cases identified by our cancer registry and departmental database. Treatment regimens were divided into three categories: sequential therapy with six cycles of carboplatin/taxane followed by EBRT, concurrent cisplatin for two cycles with EBRT followed by four cycles of carboplatin/taxane, or ‘sandwich’ therapy with three cycles of carboplatin/taxane followed by EBRT followed by three cycles of carboplatin/taxane. The published results of the phase III GOG-258 study called into question the efficacy of concurrent chemoradiation. Therefore, we only compared sequential versus ‘sandwich’ therapy using a Chi-Square analysis. We conducted a retrospective chart review to assess if patients were able to complete the prescribed six cycles and EBRT, and then measured their PFS at two years. We hypothesized that there would be no difference in PFS between the two groups. Results: There were no significant differences in clinical or pathologic factors between patients treated with either regimen. Ninety-four patients (65%) had stage IIIC disease. The majority of patients received six cycles of paclitaxel with carboplatin. Median EBRT dose was 45 Gy. There was no statistically significant difference in the estimated 2-year PFS between the sequential and ‘sandwich’ groups, which were 82% and 82.5%, respectively (p = 0.84). Conclusions: Adjuvant chemoradiation for FIGO stage III endometrial cancer given sequentially or in a ‘sandwich’ fashion appears to offer equally excellent early clinical patient outcomes.

e17518 Background: Morbidity and mortality for patients with cervical cancer has improved significantly over the past few decades with modern multimodal therapy. However, neuroendocrine carcinoma of the uterine cervix (NCUC), which accounts for 1-2% of cervical cancers, remains a deadly subtype. In this study, we combine data from Mayo Clinic (MC) and the University of Iowa Hospitals and Clinics (UIHC) to provide information on tumor characteristics, treatment, and outcomes. Methods: The electronic medical record was reviewed for patients with NCUC from MC and UIHC. Data on diagnosis, treatment, and outcomes were collected through chart review. Primary endpoints included progression-free survival (PFS) and overall survival (OS). Secondary endpoints included median survival, survival at 1 year after surgery, and survival at 1 year by first line chemotherapy agent. Kaplan-Meier survival analysis was used to estimate median PFS, median survival, and OS. Fisher’s test analysis was used to calculate survival at 1 year after surgery and by first line chemotherapy agent. Results: There were 62 patients (MC: 26, UIHCC: 36) with NCUC stage I-IV (stage I: 29, stage II: 9, stage III: 7, stage IV: 14, unknown: 3). Median age of diagnosis was 47 years (range 21-77 years). By subtype, 47 were small cell (76%), 9 were large cell (15%), and 6 were unknown/undetermined (9%). The initial treatment modalities for each patient are outlined in the table. 28 patients had complete/partial response or stable disease from first line treatment, while 10 patients had disease progression. Of the patients who initially responded or had stable disease, 16 later progressed (57%) with a median time to progression of 15 months. Median follow up was 65.1 months with a median OS of 28.5 months. Median survival for those with stage I was 40.9 months, stage II: 54.6 months, stage III: 8.75 months, and stage IV: 11.7 months. There was a significant difference in overall survival at 1 year between those who received surgery and those who did not in stage I/II ( p = 0.01). There was no significant difference in overall survival at 1 year for those who received surgery in stage III/IV. There was no statistical difference in survival at 1 year for carboplatin or cisplatin in combination with etoposide as first line chemotherapy agent. Conclusions: NCUC is an aggressive malignancy that is usually progressive despite multimodal therapy. Our study demonstrated a median overall survival of 28.5 months and 5-year survival rate of 21%. Our study showed a survival benefit at 1 year for those who receive surgery with stage I/II NCUC. There was no significant survival benefit at 1 year between carboplatin or cisplatin in combination with etoposide as first line agent.[Table: see text]
