Background. There are some patients with SCLC that are diagnosed in the operating room by cryosection and surgeons had to perform surgical resection for these patients. The aim of this study is to compare the effective of pneumonectomy with lobectomy for SCLC. Methods. A retrospective study was undertaken in 75 patients with SCLC that were diagnosed by cryosection during surgery. 31 of them underwent pneumonectomy, 44 underwent lobectomy. Local recurrence rate and survival rate according to surgical procedures and cancer stages were analyzed. Results. There was significant difference in the overall survival rate between lobectomy and pneumonectomy groups (P=0.044). For patients with stage II SCLC, the overall survival rate after pneumonectomy was significantly better than after lobectomy (P=0.028). No significant difference in overall survival rate was found between the two surgical groups in patients with stage III SCLC (P=0.933). The local recurrence rate in lobectomy group was significant higher that in pneumonectomy group (P=0.0017). Conclusions. SCLC was responsive to surgical therapy. When surgeons have to select an appropriate method of operation for patients with SCLC during surgery, pneumonectomy may be the right choice for these patients. Pneumonectomy can result in significantly better local control and higher survival rate compare with lobectomy.

Abstract Background Chondrosarcoma (CS) most commonly involves the pelvis. This study aimed to analyze differences in clinical characteristics and prognostic factors between primary and secondary conventional pelvic CS, and provide reference for clinical diagnosis and treatment. Methods Eighty patients (54 primary cases and 26 secondary cases) with pelvic CS were included in this retrospective study. The tumor site, Enneking stage, soft tissue mass, margin, initial tumor grade, incidence of local recurrence and distant metastasis were evaluated. Kaplan-Meier method was used to calculate the overall survival rate. X2 test and log-rank test were used for univariate analysis, and Cox test was used in multivariate analysis. Results The average age of patients with secondary CS was significantly younger than that of patients with primary CS (P < 0.001). The soft tissue mass of patients with secondary CS was significantly larger than that of patients with primary CS (P = 0.002). There was a significant difference in initial tumor pathologic grade between the two groups (P = 0.002). No statistically significant difference was observed in the local recurrence rate between the two groups. The median recurrence time of patients with primary CS after the first treatment was significantly shorter than that of patients with secondary CS (P < 0.001). The overall survival rate of patients with secondary CS was much higher than that of patients with primary CS (P = 0.003). Cox regression analysis showed that the initial tumor grade was an independent factor in the overall survival rate of patients with CS. Conclusion There were significant differences in age, soft tissue mass, initial tumor grade, and overall survival rate between the two groups. The overall survival rate of pelvic CS was related to the initial tumor grade of CS.

A retrospective review of 193 previously untreated patients with primary supraglottic carcinoma was undertaken to ascertain the efficacy of postoperative radiotherapy. All the patients received a supraglottic laryngectomy, and patients received a total of 284 elective or therapeutic neck dissections. Ninety-four (48.7%) of the patients received postoperative radiotherapy. The incidence of local recurrence was 8.2%, but the recurrence rate was unrelated to the use of postoperative radiotherapy. Neck recurrence was observed in 12.9% of patients, with no influence of postoperative radiotherapy in the dissected neck. The incidence of locoregional recurrences by stage in irradiated and nonirradiated patients did not reach significant difference. The 3-year survival was 74.3%. The overall survival of the whole series and by stage was not statistically altered in combined therapy compared to surgery.

19508 Background: To analyse the five-year survival rate in patients with proximal femoral tumours after total hip replacement. Methods: Between the period of 1994–2003, 50 patients were operated (Total Hip Replacement) for proximal femoral tumours at the Department of General Oncology (Bone & Soft tissue tuomurs), N. N. Blokhin Cancer Research Institute & Moscow Regional Clinical Research Institute, Moscow, Russian Federation. The histological diagnoses included 14 - metastases, 10 - osteosarcoma, 8 - chondrosarcoma, 4 - Ewing’s sarcoma, 4 - Giant cell tumor, 3 - malignant fibrous histiocytoma, 2 paraosteal and 2 periosteal osteosarcoma, and 1 each from primary neuroectodermal tumor, myeloid disease, and aneurysmal bone cyst. The follow-up ranged from 1–9 years (mean follow-up 5 years). 21 patients (45.7%) had pathological fracture. The cause of the pathological fracture was metastasis in 12 patients (26%). 28 patients (60.8%), had soft tissue invasion. All the survival analyses were done using Kaplan-Meier survivorship analysis method. Functional outcome was estimated using Enneking’s evaluation criteria. Results: The overall survival rate of patients was 66.7% at 5 years. 2 patients had local recurrence.12 patients had metastases after surgery. In that 11 patients were died. There was no evidence of disease in 32 patients. In 3 patients, we performed disarticulation of the hip joint because of the local recurrence. The overall survival rate of limb was 92.7% at 5 years. The overall survival rate of prostheses was 84.2% at 5 years. At the latest follow up, functional outcome was excellent in 15 (30%) patients, good in 27 (54%) patients, fair in 5 (10%) patients, poor in 3 (6%) patients. Conclusions: Though the extent of the muscle and bone resection is large, there is no doubt that endoprosthetic replacement of the proximal femur provides a good functional and oncological outcome when compared with the various other reconstructive surgeries.

Stage Ii Colon Cancer

625 Background: Surgical resection of local colon cancer is the only curative treatment, at the same time adjuvant chemotherapy is clearly shown to be beneficial as the standard of care for node positive disease (stage III) colon cancer. However the role of chemotherapy for stage II colon cancer treatment is still conflicting. We aim to compare the overall survival rate of stage II colon cancer patient's with and without chemotherapy. Methods: A retrospective observational study was conducted from 1990-2006. Patients with stage II colon cancer were included. Patient's characteristics including age, gender, common site of involvement, histology patterns, overall survival rate and treatment with chemotherapy were recorded. Results: A total of 138 consecutive patients were identified from 1990-2006. The median age was 68 (21-91) year, males (44%), African Americans (47.6%). The most common sites of the primary tumor were sigmoid and cecum (22.4%) each. Adenocarcinoma being the most common pathology. Majority of the patients (86.2%) were found to have T 3 tumors. Of the patients that received chemotherapy (29/44) 66% had an overall survival rate of three years or more, whereas (53/94) 57% of the patients who did not receive chemotherapy had a survival rate of three years or more. The difference of survival rates between the two groups of patients was not statistically significant. Conclusions: The role of chemotherapy in stage II colon ancer is still controversial. There was no significant difference in overall survival between the two groups who did and did not receive chemotherapy; thus more studies are warranted to explore the factors that predict the survival of stage II colon cancer. No significant financial relationships to disclose.

144 Background: The aim of this study is to evaluate the long-term clinical and oncologic outcome of ESD for differentiated EGC of an expanded indication compared to surgical resection. Methods: Retrospective analyses were performed in patients who underwent ESD or surgical resection for EGC of an expanded indication from 2006 and 2008 in Incheon St. Mary’s Hospital, Seoul St. Mary’s Hospital, Yeouido St. Mary’s Hospital, and St. Paul’s Hospital. First arm study was performed according to pre-ESD diagnosis including pathologic diagnosis and endoscopic findings. Second arm study was obtained from post-ESD final pathologic result. All the patients were checked with endoscopy and stomach CT regularly at least 5 years. Clinical outcomes, disease free survival and overall survival were compared between the ESD group and surgical resection group in each arm. Results: In first arm study, 41 patients who received ESD and 106 patients who received surgical resection were enrolled. Metachronous recur was found in 4 patients among ESD group and in 2 patients among surgical resection group during the follow up period. There was no local recurrence in both groups. The disease free survival was not different between the two groups (ESD vs surgical resection; 87.8 vs 95.3%, p=0.291). The 5-year overall survival rate was 100% in both groups. In second arm study, 74 patients who received ESD and 165 patients who received surgical resection were enrolled. Metachronous recur was found in 5 patients among ESD group and in 2 patients among surgical resection group during the follow up period. Local recurrence did not occur in both groups. Surgical resection group was superior to ESD group in disease free survival (97.6% vs 87.6%, p=0.002). The 5-year overall survival rate was 100% in both groups. Conclusions: ESD for EGC might be acceptable considering the overall survival rates. However, intensive surveillance should be performed to find the metachronous recur after ESD.

The Impact

288 Background: Obesity is a risk factor for developing cholangiocarcinoma (CCA). However, the effect of obesity on survival of CCA is unclear. The primary aim of this study was to analyze the impact of obesity upon overall survival of CCA patients. Secondary aims were to analyze impact of obesity upon other disease characteristics such as tumor site, stage, age, sex, BMI and Ca 19-9. Methods: A total of 411 unique pts diagnosed with CCA at Mayo Clinic Florida between 2000 and 2018 were retrieved from our collective SDMS database. Variables evaluated included:demographics, Body Mass Index (BMI), AJCC stage, tumor location and Ca 19-9.A total of 185 pts had all data available pertaining to these variables. We further restricted the analysis to pts with intrahepatic CCA classified BMI as per CDC criteria normal (18.5-25kg/m2), overweight (25-29.9kg/m2) and obese (≥30 kg/m2), thus leaving a total of 152 pts. Continuous and categorical variables were compared across BMI groups using Chi-squared or Fisher’s exact test. Overall survival rates after diagnosis at 1, 2 and 3 years were estimated using Kaplan-Meier method. Results: Among 152 pts included in the study, 28% were normal weight, 40% were overweight and 32% were obese. The overall survival rate at 1, 2 and 3 years for normal weight pts with all stages combined was 54.1%, 35%, and 30.7%, respectively. The overall survival rate at 1, 2 and 3 years for overweight pts with all stages combined was 59.7 %, 32.6%, and 25.4%, respectively. The overall survival rate at 1, 2 and 3 years for obese pts with all stages combined was 63.9%, 37.6%, and 26.7%, respectively(p = 0.8766). Multivariate analysis demonstrated is no significant difference in overall survival for obese pts compared to normal or overweight pts.(Table to be shown) However it showed, gender and Ca19-9 were statistically significant predictors of overall survival, with males and pts with Ca19-9≥100 doing worse (HR1.65 (CI = 1.05, 2.61, p = 0.031) and HR 2.31 (CI = 1.49, 3.59, p = < 0.01), respectively). Conclusions: BMI did not make a significant impact on the overall survival, though there may be a trend toward worse OS for ptswith higher BMI. A larger, stage focused evaluation is warranted for further exploration of this trend.

Objectives: Chondrosarcomas are rare tumors with a variable biological characteristic. Their treatment clinically and surgically is controversial. Analysis of the clinical statistics and prognostic factors of pelvic chondrosarcoma provides a reference for clinical diagnosis and treatment. Methods: A total of 73 cases of chondrosarcoma were collected, including 24 pelvic samples, from 2008 to 2017 from the hospital database and divided into two groups: pelvic chondrosarcoma and non-pelvic chondrosarcoma. The clinical characteristics and prognostic factors of pelvic chondrosarcoma were analyzed using different statistical methods. Results: Among the 24 pelvic chondrosarcoma patients, the ratio of male to female was 1.4:1, and the median age was 43.5 years. According to the classification proposed by Enneking, there were five grade I, 14 grade II, and five grade III. Histological grading of chondrosarcoma was grade I in one case, II in 15 cases, and III in eight cases. The histological type was 17 conventional, three dedifferentiated, two secondary, one myxoid, and one mesenchymal. The overall survival rates for 24 cases at three, five, and 10 years were 82.2±8.1%, 77.3±8.9%, and 52.4±12.1%, respectively. The local recurrence rate of pelvic chondrosarcoma after surgical resection (83.3%) was significantly higher than that of other sites (34.7%), and the difference was statistically significant (p < 0.001). The final proportion of amputation rate (50.0%) was also higher than other parts (20.4%), with a statistically significant difference (p =0.010). The total survival of the two groups was not significantly different (p =0.216). Conclusions: Chondrosarcoma of bone generally has an excellent prognosis when optimally diagnosed and treated by an experienced team of specialists. Pelvic chondrosarcoma has a higher local recurrence rate than the other sites and tends to result in amputation. Early local recurrence after surgery indicates a poor prognosis.

Aim: To compare efficacy between total gastrectomy (TG) and proximal gastrectomy (PG) for upper-third gastric cancer. Materials & methods: PubMed, Embase and Cochrane library were searched to select suitable researches. Stata was used for meta-analysis including 5-year overall survival rate, recurrence rate, complication morbidities and serum nutritional levels. Results: Ten retrospective English researches were contained. Our study showed no significant difference of 5-year overall survival rate, recurrence rate, reflux symptoms and anastomotic leakage. TG experienced longer operation time, more lymph nodes-retrieved number, more estimated blood loss and higher ileus, but less anastomotic stricture. PG showed advantages over TG in terms of serum nutritional levels. Conclusion: PG is more preferable to TG for treatment of upper-third gastric cancer.
