PURPOSE The purpose of this study was to investigate the significance of epidermal growth factor receptor (EGF-R) expression in a group of advanced ovarian carcinomas. PATIENTS AND METHODS The study was conducted on 72 previously untreated patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IV disease. The median follow-up was 24 months (range, 4 to 75 months). EGF-R was measured by a radioreceptorial assay. A cutoff of 1.5 fmol per milligram of protein was chosen to define EGF-R positivity. Medians and life tables obtained with the Kaplan and Meier method were analyzed by the log-rank test. The risk of progression was estimated by Cox's proportional hazards model. RESULTS EGF-R was detected in 54% of primary tumors. When EGF-R was analyzed in different tissue specimens of the same tumor, consistent findings were noted in 88% (seven of eight) of cases. A lower concordance rate (nine of 15; 60%) was found between primary tumors and omental metastases, with a tendency toward higher EGF-R levels in the latter. The EGF-R expression did not significantly correlate with age, stage, grading, and residual tumor after primary surgery. In the univariate analysis, stage IV disease, postoperative residual tumor diameter greater than 2 cm, presence of ascites, and EGF-R positivity were found to be significantly associated with a greater risk of disease progression. In the multivariate analysis, only the postoperative residual tumor and the EGF-R expression remained significantly associated with a high risk of progression. CONCLUSION Data reported here suggest that the presence of EGF-R in advanced ovarian tumor at the time of the primary surgery identifies a subset of patients with a particularly poor prognosis.

Purpose To evaluate the value of lymphatic vessel invasion (LVI) as a predictor of survival in patients with primary resected adenocarcinomas of the esophagogastric junction (AEG). Patients and Methods We prospectively evaluated 459 patients undergoing primary surgical resection for tumors of the esophagogastric junction at our institution between 1992 and 2000 (180 adenocarcinomas of the distal esophagus, AEG I; 140 carcinomas of the cardia, AEG II; and 139 subcardial gastric cancers, AEG III). Median follow-up was 36.8 months. The prevalence of LVI was evaluated by two independent pathologists. Univariate and multivariate analysis of prognostic factors was performed. Results The total rate of LVI was 49.9%, with a significant difference between AEG I (38.9%) and AEGII/III (57.0%, P = .0002). Univariate analysis showed a significant correlation between LVI and T category (P < .0001), N category (P < .0001), and resection status (R [residual tumor] category; P < .0001). This was shown for the group of all AEG tumors, as well as for the subgroups AEG I and AEG II/III. On multivariate analysis, LVI was identified as a significant and independent prognostic factor (P = .050) in the population of all patients and in patients with AEG II/III, but not in the subgroup with AEG I. Conclusion These data demonstrate the prognostic significance of LVI in patients with AEG tumors, with marked differences between the subgroups AEG I versus AEG II/III. The lower prevalence and lack of prognostic significance of LVI in AEG I might be explained by inflammation involved in the pathogenesis of this entity.

750 Background: Perineural invasion (PNI) as a prognostic indicator has not been well studied in patients with rectal adenocarcinoma treated with neoadjuvant chemoradiation (nCRT). In this study, we investigated the incidence and prognostic significance of PNI in patients with stages II-III locally advanced rectal cancer treated with nCRT. Methods: We performed a retrospective study of 110 consecutive patients treated with nCRT for locally advanced rectal adenocarcinoma at a single institution from 2004 to 2011. 88 of these patients had residual tumor in the resected specimen after nCRT. We evaluated the association of PNI with clinical outcomes, including disease-free survival (DFS), distant-metastasis-free survival (DMFS), and overall survival (OS), using log-rank and Cox proportional hazard modeling. Results: Of the 88 patients with residual tumor at surgery, 14 patients (16%) had PNI and 74 patients (84%) did not. Baseline distribution of selected variables in the PNI+ and PNI- groups are shown in Table 1. Median follow-up was 27 months (range 0.9 to 84 months). The median DFS was 13.5 months for PNI+ patients and 39.8 months for PNI- patients (p<0.0001). The median DMFS was 13.5 months for PNI+ patients and median not reached (> 40 months) for PNI- patients (p<0.0001). We did not detect a significant association between the presence of PNI and worse OS, perhaps due to a high rate of censored patients in the OS analysis. In a multivariate model including pT stage, pN stage, tumor location, tumor size, type of surgery, and radial margin status, PNI remained a significant predictor of DFS (HR 16.8, 95% CI, 3.7–75.5, p<0.0002) and DMFS (HR 18.9, 95% CI, 4.4–81.9, p<0.0001). Conclusions: For patients with locally advanced rectal cancer treated with nCRT prior to surgical resection, PNI found at the time of surgery is significantly associated with worse DFS and DMFS.

15025 Background: In the past years the concept of neoadjuvant chemotherapy and interval laparotomy has emerged for patients with advanced ovarian cancer and unfavorable prognosis (e.g. diffuse peritoneal carcinosis). In a recent study on neoadjuvant chemotherapy higher tumor resection rates and longer median survival were demonstrated in patients with advanced ovarian carcinoma and ascites >500ml. Most studies use three cycles of preoperative chemotherapy. However, chemoresistant tumorclones may be induced by increasing number of preoperative chemotherapy cycles. The purpose of this study is to evaluate the optimal number of cycles prior to interval laparotomy. Methods: 67/73 patients with advanced serous ovarian carcinoma (FIGO IIIc n = 48, FIGO IV n = 19) and ascites >500ml were randomized into two arms, receiving either 2 (n = 33) or 3 (n = 34) cycles of Carboplatin (AUC5) and Docetaxel (75mg/m2) before interval laparotomy. Postoperatively, they received either 4 or 3 additional cycles. Response rate and postoperative residual tumor were evaluated. Results: Surgical response was assessed during interval laparotomy. At present 32 patients underwent tumordebulking. Partial remission was observed in 28/32 patients irrespective of the number of preoperative chemotherapy cycles. Two patients in each arm showed stable disease. Optimal cytoreduction was achieved in 25/32 patients. No severe adverse events were reported. Six of 73 patients were not eligible. Two patients were excluded due to therapy-unrelated events. In 4 patients ovarian cancer was excluded by laparoscopy prior to neoadjuvant chemotherapy. Conclusions: Neoadjuvant chemotherapy followed by interval laparotomy was safe and well tolerated. Diagnostic laparoscopy prior to neoadjuvant chemotherapy allowed differentiation of primary ovarian cancers from tumors of other origin. In these cases laparotomy could be circumvented. Optimal tumor reduction was achieved in a significant number of patients. Response rate and postoperative residual tumor were essentially the same in both arms. Our data indicate that two cycles of preoperative chemotherapy may be the preferential choice of therapy for future studies. No significant financial relationships to disclose.

Object. For patients with recurrent glioblastomas multiforme (GBMs) the prognosis is poor. Although chemotherapy may provide a survival advantage, the role of the extent of tumor resection, or the volume of the residual tumor at the time of recurrence, before instituting chemotherapy, is unclear. This study was designed to assess the response to chemotherapy based on the volume of residual disease (VRD) at the start of treatment in patients with recurrent GBMs. To accomplish this, the authors evaluated a homogeneous group of patients with recurrent GBMs who received the same chemotherapeutic agent. Methods. One hundred nineteen adult patients with recurrent supratentorial GBMs received temozolomide chemotherapy at the time of tumor recurrence. In this cohort the authors analyzed the prognostic significance of volumetrically assessed tumor mass on time to tumor progression (TTP) and survival time (ST). Multivariate analysis demonstrated that the VRD at the beginning of chemotherapy was a statistically significant predictor of both TTP (p < 0.0001) and ST (p < 0.006) when adjusted for the patient's age, performance score, and time from the initial diagnosis. Patients in whom the VRD was less than 10 cm3 at the start of chemotherapy had a 6-month progression-free survival rate of 32% compared with 8% for patients with a VRD between 10 and 15 cm3 and 3% for patients with a VRD larger than 15 cm3. Patients in whom the VRD was smaller than 10 cm3 had a 1-year survival rate of 37% compared with 9% for patients with a VRD between 10 and 15 cm3 and 18% for patients with a VRD larger than 15 cm3. Conclusions. These data indicate that patients with recurrent GBMs who start chemotherapy with a smaller volume (< 10 cm3) of residual disease may have a more favorable response to chemotherapy and a more favorable outcome.
