PURPOSE: In osteosarcoma, prognostic factors at diagnosis other than clinical stage have not been clearly identified. The aim of this study was to determine whether human epidermal growth factor receptor 2 (HER2)/erbB-2, p-glycoprotein, or p53 expression correlated with histologic response to preoperative chemotherapy or event-free survival. PATIENTS AND METHODS: We performed a retrospective immunohistochemical study on material obtained from patients treated on the Memorial Sloan-Kettering Cancer Center T12 protocol between 1986 and 1993. Paraffin-embedded tissue was identified from 53 patients (73% of patients enrolled onto protocol) and stained for HER2/erbB-2, p53, and p-glycoprotein expression using standard monoclonal antibodies and methods. RESULTS: At the time of initial biopsy, 20 (42.6%) of 47 samples demonstrated high levels of HER2/erbB-2 expression. Higher frequencies of expression were observed in samples from patients with metastatic disease at presentation and at the time of relapse. Expression of HER2/erbB-2 correlated with a significantly worse histologic response (P = .03). In patients presenting with nonmetastatic disease, expression of HER2/erbB-2 at the time of initial biopsy was associated with a significantly decreased event-free survival (47% v 79% at 5 years, P = .05). p53 and p-glycoprotein expression did not correlate with histologic response or patient event-free survival. CONCLUSION: The correlation of HER2/erbB-2 expression with histologic response to preoperative chemotherapy and event-free survival in this study suggests that HER2/erbB-2 should be evaluated prospectively as a prognostic indicator. The correlation also suggests that clinical trials of antibodies that target this receptor, such as recombinant humanized anti-HER2 monoclonal antibody (Herceptin; Genentech, San Francisco, CA), should be considered for the treatment of osteosarcoma.

74 Background: This trial sought to evaluate the efficacy and safety of preoperative chemotherapy with DTX plus S-1 for advanced gastric cancer with poor prognosis even after R0 curative resection. We show the 2 years follow-up data. Methods: Preoperative staging was confirmed by laparoscopy. Eligibility criteria included 1) negative peritoneal cytology, H0, P0 and M0, 2) possible curative resection, and 3) ECOG PS 0-1. Patients received DTX (35 mg/m2) on days 1 and 15, and daily oral administration of S-1 (80 mg/m2/day) for days 1–14 every 4 weeks of 2 courses, followed by gastrectomy with D2 lymphadenectomy. The primary endpoint was pathological response rate (pRR). A sample size of 45 was planned for the expected pRR of 40% and threshold value of 20%, with one-sided alpha of 0.05 and beta of approximately 0.1. Results: A total of 47 patients were centrally registered between November 2007 and November 2009 from 14 centers. All patients were eligible for analysis. The median age was 63 (range 37–79); male/female: 36/11; PS0/1:41/6; and clinical stage IIIA/IIIB: 31/16. The target pRR was 47% (90%CI, 34–60%; p<0.0001). Forty six patients (98%) underwent surgery, in whom curative resection was performed in 44 patients, and 37 patients completed the protocol treatment. The response to preoperative chemotherapy was PR/SD/PD/NE in 16/24/2/5 with a response rate of 34%. The rate of 2 years and 3 years DFS were 53.9%, and 49.3%, respectively. The rate of 2 years and 3 years Overall survival were 69.6%, and 55.1%, respectively. The most common toxicities of neoadjuvant chemotherapy were grade 3/4 neutropenia (42%), febrile neutropenia (4%), grade 2 anorexia (21%), and fatigue (15%). Major operative morbidity included pancreatic fistula (9%), abdominal abscess (11%), pneumonia (2%), and anastomotic leakage (0%). No patients died due to surgical complications. Conclusions: The combination of DTX and S-1 was well tolerated and promising as a preoperative chemotherapy regimen for patients with potentially resectable advanced gastric cancer.

Abstract Background In Japan, preoperative chemotherapy followed by surgery is the standard treatment for clinical stage II or III, excluding T4 thoracic esophageal squamous cell carcinoma (SCC). Here, we investigated the efficacy of preoperative chemotherapy in our hospital. Methods From January 2010 through December 2017, 33 patients with clinical stage II/III esophageal SCC underwent esophagectomy after preoperative chemotherapy with two cycles of cisplatin and 5-fluorouracil. Overall survival (OS) and clinical and pathological tumor responses were retrospectively evaluated. In addition, fluorodeoxyglucose (FDG) uptake was assessed by FDG-positron emission tomography/computed tomography (PET/CT). Results There were 9 patients with stage II and 24 with stage III esophageal SCC, and two cycles of chemotherapy were completed by 27 patients (81.8%). Three-year OS rates were 100% in patients with stage II and 66.7% in patients with stage III esophageal SCC, whose observation period exceeded beyond 3 years. Of the 33 patients who showed a clinical response at the primary site, 22 (66.7%) had a partial response (PR), and a 3-year OS of 85.7%, while 4 (12.1%) had a complete response (CR), and a 3-year OS of 100%. In regards to pathological response, as evaluated using The Japan Esophageal Society histological evaluation criteria, 3 patients (9.1%) were classified as grade 0, 18 (54.5%) as grade 1a, 4 (12.1%) as grade 1b, 6 (18.2%) as grade 2, and 2 (6.1%) as grade 3. Of the 22 patients who achieved PR, 14 (63.6%) were classified as either grade 0 or 1a. On the other hand, when we compared the maximum standardized uptake value (SUVmax) of FDG − PET/CT at the primary site before and after preoperative chemotherapy, the patients with high decreasing rates mostly belonged to the grade 1b-3 group. The OS rate tended to be higher in the grade 1b-3 group than in the grade 0–1a group. Conclusion Our present results suggest that, although pathological responses do not necessarily correspond to clinical tumor reduction, a good pathological response is potentially related to a better prognosis. Furthermore, the FDG uptake value may reflect pathological effects that occur owing to preoperative chemotherapy. Disclosure All authors have declared no conflicts of interest.
