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.

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.

Background: Recent attempts have focused on identifying fewer magnitude of minimal residual disease (MRD) rather than exploring the biological and genetic features of the residual plasma cells (PCs). Interphase fluorescence in situ hybridization (iFISH) analyses in sequential samples provide a simple and reliable method to longitudinal track the dynamic changes in clonal architecture and speculate the possible evolutionary pattern. Here, we report for the first time the incidence and prognostic significance of cytogenetic abnormalities (CA) existed in the PCs of patients achieving at least partial remission. Methods: A cohort of 193 patients with at least one CA at diagnosis were analyzed using data from the prospective, non-randomized clinical trial (BDH 2008/02), and iFISH analyses were performed in patient-paired diagnostic and post-therapy samples. Results: Persistent CA in residual tumor cells were observed for the majority of patients (63%), even detectable in 28/63 (44%) patients with MRD negativity (<10-4). The absence of CA in residual PCs was associated with prolonged survival regardless of MRD status. It was noted that MRD-positive but FISH-negative patients experienced similar survival to MRD-negative patients (m-TTP 4.5 vs. 5.1 years, P=0.983). According to the change of the clonal size of specific CA, patients were clustered into five groups, reflecting five patterns of clone selection under therapy pressure. 1) Pattern A were observed in 36 (19%) patients where a minor subpopulation or undetectable subclone in the pre-treatment sample became dominant after therapy. 2) Pattern B was identified in 29 (15%) patients whose fractions of PCs harboring different CA were decreased with inconsistent extent. 3) Identical CA fraction in residual PCs were found in 22 (11%) patients as Pattern C. 4) Pattern D. The fractions of PCs harboring specific CA in 35 patients (18%) were uniformly declined. 5) 71 patients lost their abnormal cytogenetic clone after therapy (less than cut-off level) were classified as Pattern E. The cytogenetic dynamics of pattern A and B can be interpreted as a therapy-induced selection process with comparable inferior survival (m-TTP 1.2 vs. 1.6 years, respectively). Patients with pattern E experienced the most favorable outcome (m-TTP 5.0 years), following those with pattern D and C (m-TTP 3.5 and 2.5 years). Among the 65 patients with clonal selection, 24 underwent upfront auto-transplantation that experienced significantly improved survival. However, upfront transplant failed to completely reverse the inferior outcome caused by therapy-induced clonal selection. Longitudinal cytogenetic studies at relapse were available in 43 patients. The results suggested that sequential cytogenetic dynamics were observed in most patients, and the cytogenetic architecture of residual cells could to some extent predict the evolutional pattern at relapse. Conclusions: The repeat cytogenetic evaluation in residual cells could not only serves as a good complementary tool for MRD detection, but also provides a better understanding of clinical response and clonal evolution. Therapy-induced clonal selection was associated with inferior outcome regardless of the baseline cytogenetic profiles. The early identification of resistant clone may contribute to guide better tailored therapy strategies based on the feature of the residual tumor cells.

It has been suggested that histologic subtype of ovarian cancer is a factor that determines the chemoresponsiveness of tumor. In this study, we wanted to clarify the prognostic significance of histologic subtype and its correlation to expression of chemoresistance-related proteins (CRPs) in ovarian cancer. A total of 93 stage II-IV ovarian cancers, where the proportion of serous, endometrioid, mucinous, and clear cell subtype was 61.3%, 14.0%, 7.5%, and 17.2%, respectively, were investigated for glutathione S-transferase-pi (GST-pi), MDR (multidrug resistance)-1, and p53 expression using immunohistochemistry. GST-pi expression was detected in 62.4% of the tumors and was not related to histologic subtype of tumor. MDR-1 expression was observed in 12.9% of the tumors tested and was more frequently detected in clear cell adenocarcinomas than other histologic subtypes of tumor (10/ 16 vs. 2 / 77, P < 0.001). P53 expression was found in 49.1% of serous, 53.8% of endometrioid, and 50% of mucinous adenocarcinomas. In contrast, none of 16 clear cell adenocarcinomas showed positive p53 staining. In univariate analysis, no direct correlations were found between CRPs and overall survival. Histology of mucinous/clear cell tumors (P = 0.0063), as well as FIGO stage III/IV (P = 0.0091) and residual tumor ≥ 2 cm (P = 0.0045), was found to have independent prognostic value in multivariate analysis. In conclusion, histologic subtype proved to be the significant independent prognostic factor in addition to FIGO stage and residual tumor in stage II-IV ovarian cancer. GST-pi, MDR-1, and p53 expression pattern is closely related to histologic subtype of ovarian cancer, although they are not significant predictors of survival.

Abstract PurposePreoperative chemotherapy is widely applied to high-grade localized soft tissue sarcomas (STSs); however, the prognostic significance of histological response to chemotherapy remains controversial. This study aimed to standardize evaluation method of histological response to chemotherapy with high agreement score among pathologists, and to establish a cut-off value closely related to prognosis. MethodsUsing data and specimens from the patients who had registered in the Japan Clinical Oncology Group study, JCOG0304, a phase II trial evaluating the efficacy of perioperative chemotherapy with doxorubicin (DOX) and ifosfamide (IFO), we evaluated histological response to preoperative chemotherapy at the central review board.ResultsA total of 64 patients were eligible for this study. The percentage of viable tumor area ranged from 0.1% to 97.0%, with median value of 35.7%. Regarding concordance proportion between pathologists, the weighted kappa coefficient (κ) score in all patients was 0.71, indicating that the established evaluation method achieved substantial agreement score. When the cut-off value of the percentage of the residual tumor area was set as 25%, the p-value for the difference in overall survival showed the minimum value. Hazard ratio of the non-responder with percentage of the residual tumor < 25%, to the responder was 4.029 (95% confidence interval 0.893–18.188, p = 0.070). ConclusionThe standardized evaluation method of pathological response to preoperative chemotherapy showed a substantial agreement in the weighted κ score. The evaluation method established here was useful for estimating of the prognosis in STS patients who were administered perioperative chemotherapy with DOX and IFO.Trial registrationUMIN Clinical Trials Registry C000000096.
