7523 Background: Patients with stage IV adenocarcinoma whose tumors harbor EGFR mutations have high rates of response (∼ 75%) and prolonged progression free survival after EGFR tyrosine kinase inhibitor (TKI) treatment. Adjuvant cisplatin-based chemotherapy improves disease free survival (DFS) and overall survival (OS) in patients with resected stages IB-IIIA NSCLC. To see if adjuvant treatment with EGFR TKI (gefitinib or erlotinib) improves DFS in patients with EGFR mutation NSCLC, we conducted a retrospective review of patients with resected lung adenocarcinoma harboring EGFR mutations, some of whom received EGFR TKIs postoperatively. Methods: With Institutional Review Board approval, clinical information was obtained on all patients with stage I-III lung adenocarcinoma harboring EGFR exon 19 or 21 mutations that underwent resection at MSKCC between May 2002 and August 2008. Age, gender, type of surgery, histology, EGFR mutation status (exon 19 deletions and exon 21 L858R), stage, perioperative therapy and survival were recorded. Kaplan-Meier analysis and Cox regression analysis were performed. Results: We studied 150 patients (112 women, 38 men) with completely resected stage I-III lung adenocarcinoma whose resection specimens contained EGFR activating mutations in exon 19 or 21. Median age was 69. Forty two patients (28%) received cytotoxic chemotherapy. Forty eight (32%) received either erlotinib (n=26) or gefitinib (n=22) postoperatively. The median time on TKI was 16 months. The median DFS was 43 months in the group that received a TKI vs. 31 months for those that did not. After controlling for stage, individuals who received adjuvant gefitinib or erlotinib had a better DFS (HR=0.38, 95%CI: 0.16–0.90) than the non-TKI group (p=0.03). The median overall survival has not been reached. Conclusions: These data indicate that the adjuvant use of either gefitinib or erlotinib improves DFS in patients with completely resected stage I -III lung adenocarcinomas with mutations in EGFR exons 19 and 21. These data justify a randomized trial in similar patients. [Table: see text]

PURPOSE: The efficacy of adjuvant chemotherapy in gastric cancer is controversial. We conducted a phase III, randomized, multicentric clinical trial with the goal of assessing the efficacy of the combination of mitomycin plus tegafur in prolonging the disease-free survival and overall survival of patients with resected stage III gastric cancer. PATIENTS AND METHODS: Patients with resected stage III gastric adenocarcinoma were randomly assigned, using sealed envelopes, to receive either chemotherapy or no further treatment. Chemotherapy was started within 28 days after surgery according to the following schedule: mitomycin 20 mg/m2 intravenously (bolus) at day 1 of chemotherapy; 30 days later, oral tegafur at 400 mg bid daily for 3 months. Disease-free survival and overall survival were estimated using the Kaplan-Meier analysis and the Cox proportional hazards model. RESULTS: Between January 1988 and September 1994, 148 patients from 10 hospitals in Catalonia, Spain, were included in the study. The median follow-up period was 37 months. The tolerability of the treatment was excellent. The overall survival and disease-free survival were higher in the group of patients treated with chemotherapy (P = .04 for survival and P = .01 for disease-free survival in the log-rank test). The overall 5-year survival rate and the 5-year disease-free survival rate were, respectively, 56% and 51% in the treatment group and 36% and 31% in the control group. CONCLUSION: Our positive results are consistent with the results of recent studies; which conclude that there is a potential benefit from adjuvant chemotherapy in resected gastric cancer.

PURPOSE: Adjuvant postoperative treatment with fluorouracil (5-FU) and levamisole in curatively resected stage III colon cancer significantly reduces the risk of cancer recurrence and improves survival. Biochemical modulation of 5-FU with leucovorin has resulted in increased remission rates in metastatic colorectal cancer, thus reflecting an increased tumor-cell kill. The impact of 5-FU plus leucovorin on survival and tumor recurrence was analyzed in comparison with the effects of 5-FU plus levamisole in the prospective multicentric trial adjCCA-01. PATIENTS AND METHODS: Patients with a curatively resected International Union Against Cancer stage III colon cancer were stratified according to T, N, and G category and randomly assigned to receive one of the two adjuvant treatment schemes: 5-FU 400 mg/m2 body-surface area intravenously in the first chemotherapy course, then 450 mg/m2 × 5 days; 12 cycles, plus leucovorin 100 mg/m2 (arm A), or 5-FU plus levamisole (Moertel scheme; arm B). RESULTS: Six hundred eighty (96.9%) of 702 patients enrolled onto this study were eligible. After a median follow-up time of 46.5 months, the 5-FU plus leucovorin combination significantly improved disease-free survival (P = .037) and significantly decreased overall mortality (P = .0089) in comparison with 5-FU plus levamisole. In a multivariate proportional hazards model, adjuvant chemotherapy emerged as a significant prognostic factor for survival (P = .0059) and disease-free survival (P = .03). Adjuvant treatment with 5-FU plus levamisole as well as with 5-FU plus leucovorin was generally well tolerated; only a minority of patients experienced grade 3 and 4 toxicities. CONCLUSION: After a curative resection of a stage III colon cancer, adjuvant treatment with 5-FU plus leucovorin is generally well tolerated and significantly more effective than 5-FU plus levamisole in reducing tumor relapse and improving survival.

205 Background: Histological phenotypic subtypes have been proposed that stratify survival in a discovery cohort of patients with stage I-III colorectal cancer (CRC). However, clinical utility has not been validated nor associations with recurrence and chemotherapy assessed. Therefore, this study assessed prognostic value in patients with stage I-III CRC as well as predictive value for recurrence and chemotherapy response. Methods: Two independent stage I-III CRC patient cohorts were utilized to assess associations between phenotypic subtypes, survival, and recurrence. Stage II-III patients, from the SCOT adjuvant chemotherapy trial, were utilized to assess associations between phenotypic subtypes and adjuvant chemotherapy response. Log rank analysis compared immune and stromal subtypes. Results: In an 867-patient internal cohort, phenotypic subtype stratified patients by disease-free survival (DFS) (HR 2.18 95% CI 2.26-4.47, p < 0.001); independent of stage and location. The stromal subtype also predicted increased local and distant recurrence (p < 0.001). In a 146-patient external validation cohort, phenotypic subtype significantly stratified patients by DFS (HR 3.43 95% CI 1.60-7.35, p = 0.001). In 1343 SCOT trial patients, phenotypic subtype significantly stratified patients by DFS (HR 1.59 95% CI 1.13-2.25, p = 0.010). Furthermore, there was evidence that the effect of regimen depended on phenotypic subtype (p = 0.048), only significantly stratifying DFS in patients receiving FOLFOX (HR 3.73 95% CI 1.58-8.81, p = 0.003) but not CAPOX (HR 0.84 95% CI 0.56-1.26, p = 0.396) adjuvant chemotherapy. Interestingly, the immune subtype associated with improved DFS in patients receiving FOLFOX compared to CAPOX adjuvant chemotherapy (HR 3.40 95% CI 1.41-8.19, p = 0.006). Whereas patients with a stromal subtype trended towards improved DFS in patients receiving CAPOX compared to FOLFOX adjuvant chemotherapy (HR 0.72 95% CI 0.50-1.05 p = 0.088). Conclusions: Histological phenotypic subtypes are an effective independent prognostic classification for patients with stage I-III CRC that can predict response to FOLFOX adjuvant chemotherapy as well as the presence of local and distant recurrence.

Abstract Purpose:Intratumoral macrophages are reportedly involved in tumor progression in non-small cell lung cancer; however, little is known about the prognostic impact and function of alveolar macrophages (AMs). This study aims to investigate the prognostic impact of the number of peritumoral AMs in patients with stage I lung adenocarcinoma.Methods:We investigated 514 patients with pathological stage I lung adenocarcinoma who underwent complete resection with lobectomy or pneumonectomy. The number of peritumoral AMs were counted, and patients were classified into two groups based on the number of peritumoral AMs. Using the Cancer Genome Atlas (TCGA) database of stage I lung adenocarcinoma, we compared gene expression profiles of high and low peritumoral AM contents.Results:The median number of peritumoral AMs per alveolar space was 15.5. Patients with a high peritumoral AM content had significantly shorter disease-free survival and overall survival than patients with a low peritumoral AM content (both p < 0.01). In the multivariate analyses, a higher number of peritumoral AMs was an independent prognostic factor (p = 0.02). The analysis of TCGA database revealed that patients with a high peritumoral AM content had shorter disease-free survival than those with a low peritumoral AM content (p = 0.04). Gene expression analysis of TCGA stage I lung adenocarcinoma revealed enrichment of biological processes, such as chemotaxis and epithelial proliferation, in patients with a high peritumoral AM content.Conclusion:The number of peritumoral AMs had a strong impact on disease-free survival in patients with stage I lung adenocarcinoma.

ObjectiveThe standard treatment for young patients with stage I malignant ovarian germ cell tumors, except stage I dysgerminoma and stage IA G1 immature teratoma, is unilateral salpingo-oophorectomy with complete staging surgery followed by platinum-based chemotherapy. However, the role of complete staging surgery and adjuvant chemotherapy remains controversial. The aim of this study was to investigate the role of complete staging surgery and adjuvant chemotherapy in patients with early-stage pure immature teratoma after fertility-sparing surgery.MethodsPatients with stage I pure immature teratoma who underwent fertility-sparing surgery between January 1986 and June 2018 were reviewed retrospectively. Fertility-sparing surgery was defined as preservation of the uterus and at least one adnexa. The inclusion criteria were age >18 years, stage I disease (confined to one ovary), and diagnosis of pure immature teratoma. Patients with distant metastasis or mixed ovarian germ cell tumor were excluded. Complete staging surgery was defined as peritoneal cytology examination, peritoneal biopsy, omentectomy, or omental biopsy with or without lymph node dissection. Patients designated with stage I disease without complete staging surgery were categorized as stage X. Disease-free survival was defined as the interval from the date of surgery to the date of recurrence or censoring. Disease-free survival curves were calculated using the Kaplan–Meier method and compared using the log-rank test.ResultsA total of 75 patients were included in the analysis, with a median age of 26 years (range 18–40): 26 (34.7%) patients had received complete staging surgery; 51 (68%) patients received postoperative adjuvant chemotherapy while 24 (32%) underwent surgery alone; and 4 patients (5.3%) had recurrent disease during a median follow-up time of 80.2 months (range 13.7–261). The recurrence rates in the chemotherapy group and surveillance groups were 3.9% and 8.3%, respectively (p=0.46). All patients were successfully salvaged, except for one death. Tumor relapse occurred in patients with all grades of immature teratoma (G1: 1/35; G2: 2/25; G3: 1/15). Univariate analysis revealed that complete staging surgery, adjuvant chemotherapy, and tumor grade were not associated with 5 year disease-free survival (p=0.69, p=0.46, p=0.7, respectively). The 5 year disease-free survival rate was 94.6% and the overall survival rate was 98.7%.ConclusionAdult patients with stage I pure immature teratoma had 98.7% overall survival and recurrence rates were low after fertility-sparing surgery.

Background: The ratio of hemoglobin to red cell distribution width (HRR) has been described as an effective prognostic factor in several types of cancer. The aim of this study was to investigate the prognostic role of preoperative HRR in resected-lung-adenocarcinoma patients. Methods: We enrolled 342 consecutive patients. Age, sex, surgical resection, adjuvant treatments, pathological stage, preoperative hemoglobin, red cell distribution width, and their ratio were recorded for each patient. Results: Mean age was 66 years (SD: 9.0). There were 163 females (47.1%); 169 patients (49.4%) had tumors at stage I, 71 (20.8%) at stage II, and 102 (29.8%) at stage III. In total, 318 patients (93.0%) underwent lobectomy, and 24 (7.0%) pneumonectomy. Disease-free survival multivariable analysis disclosed an increased hazard ratio (HR) of relapse for preoperative HRR lower than 1.01 (HR = 2.20, 95%CI: (1.30–3.72), p = 0.004), as well as for N1 single-node (HR = 2.55, 95%CI: (1.33–4.90), p = 0.005) and multiple-level lymph node involvement compared to N0 for both N1 (HR = 9.16, 95%CI:(3.65–23.0), p < 0.001) and N2 (HR = 10.5, 95%CI:(3.44–32.2, p < 0.001). Conclusion: Pre-operative HRR is an effective prognostic factor of disease-free survival in resected-lung-adenocarcinoma patients, together with the level of pathologic node involvement.
