Background The author intended to clarify the therapeutic effect and prognostic factors of metastasectomy and timing of pulmonary metastases in osteosarcoma patents. Methods Data was obtained retrospectively on all consecutive osteosarcoma patients from 1985 to 2005 in author's institute. Fifty-two patients with pulmonary nodules were identified, including 24 patients undergoing pulmonary metastasectomy treatment. These patients were categorized into four groups: group 1, patients with lung metastases at the initial presentation; group 2, lung metastases identified during the period of pre-operative chemotherapy; group 3, lung metastases identified during period of the post-operative chemotherapy; group 4, lung metastases identified after therapy for the primary osteosarcoma completed. Results In our study, the 2-, 3-, and 5-year overall survival rates for 52 patients were 49%, 39% and 20%. The 2-year overall survival rates were 18% for group 1, 32% for group 3, and 70% for group 4 (p < 0.001). The 5-year overall survival rate was 34% for group 4. Patients who underwent metastesectomy showed a better survival outcome as compared with the patients not undergoing metastasectomy (p = 0.003). The 2-year and 5-year overall survival rates of only one lung metastatic nodule were 62% and 50%, and for initially multiple lung metastatic nodules, 45% and 5%, respectively. In addition, the patients presented with lung metastases had a worse prognosis as compared with those without initial lung metastases (p = 0.0001). Conclusions The patients having single metastatic nodule showed a better prognosis than those with multiple lung nodules. Furthermore, those patients who underwent metastasectomy survived longer than those not undergoing metastasectomy. Patients who had late metastases after complete chemotherapy had a better prognosis; whereas those who had metastases identified at the initial presentation predicted a poor prognosis.

PURPOSE: The prognostic value of the time of identification of lung metastasis was investigated in 280 patients with metastatic lung osteosarcoma as a multi-institutional study of the Japanese Musculoskeletal Oncology Group. PATIENTS AND METHODS: The 280 patients with lung metastasis were divided into four groups: group 1, patients with lung metastasis identified at initial presentation; group 2, those with lung metastasis identified during preoperative chemotherapy; group 3, those with lung metastasis identified during postoperative chemotherapy, and group 4, those with lung metastasis identified after completion of treatment. Survivals of the four groups were compared. Additionally, the effects of number of metastatic nodules, metastasectomy, and the effect of chemotherapy on the primary tumor on survival of the four groups were analyzed. RESULTS: There were 46 patients in group 1, 30 in group 2, 94 in group 3, and 110 in group 4. The overall 2-year survival rates from the time of identification of lung metastasis were 33%, 31%, 24%, and 40% for groups 1, 2, 3, and 4, respectively, whereas the 5-year survival rates were 18%, 0%, 6%, and 31%, respectively. Patients in group 4 thus demonstrated significantly better prognosis than any of the other patients (P < .0001). CONCLUSION: Time of identification of lung metastasis is an important prognostic factor. In terms of clinical behavior, groups 2 and 3 are completely different than group 4. These data ensure the need to stratify stage III osteosarcomas into subgroups according to the time of diagnosis of lung metastases. To improve the survival of osteosarcoma patients, new treatment modalities should be introduced into the treatment armamentarium for lung metastasis from osteosarcoma, especially in groups 1, 2, and 3.

Objectives To investigate the pathogenicity of Klebsiella pneumoniae (KPN) possessing rmpA or the aerobactin gene in infected mice. Methods BALB/c mice were divided into four groups (n = 10 per group) and infected with: string test-positive and rmpA-positive or aerobactin-positive KPN (group 1), string test-negative but rmpA-positive KPN (group 2), string test-negative but aerobactin-positive KPN (group 3), or string test- and rmpA/aerobactin-negative KPN (group 4). Mouse survival time was compared among groups, and the infection of livers, spleens, lungs, and kidneys and KPN growth were assessed in infected mice. Results Compared with the negative group (group 4), the survival rates of mice infected with rmpA- or aerobactin-positive KPN (groups 1–3) were significantly lower, their multi-organ injuries were significantly more severe, and bacterial enumeration was significantly higher. Conclusions Despite being string test-negative, aerobactin- or rmpA-positive KPN still exhibit high virulence and anti-immune effect activity. Therefore, the combination of the string test and gene detection of aerobactin and rmpA will be helpful in screening hypervirulent KPN.

OBJECTIVE: To describe demographic characteristics, surgical results, postoperative complications, and overall survival rates in surgically treated patients with lung metastases.METHODS: This was a retrospective analysis of 119 patients who underwent a total of 154 lung metastasis resections between 1997 and 2011.RESULTS: Among the 119 patients, 68 (57.1%) were male and 108 (90.8%) were White. The median age was 52 years (range, 15-75 years). In this sample, 63 patients (52.9%) presented with comorbidities, the most common being systemic arterial hypertension (69.8%) and diabetes (19.0%). Primary colorectal tumors (47.9%) and musculoskeletal tumors (21.8%) were the main sites of origin of the metastases. Approximately 24% of the patients underwent more than one resection of the lesions, and 71% had adjuvant treatment prior to metastasectomy. The rate of lung metastasis recurrence was 19.3%, and the median disease-free interval was 23 months. The main surgical access used was thoracotomy (78%), and the most common approach was wedge resection with segmentectomy (51%). The rate of postoperative complications was 22%, and perioperative mortality was 1.9%. The overall survival rates at 12, 36, 60, and 120 months were 96%, 77%, 56%, and 39%, respectively. A Cox analysis confirmed that complications within the first 30 postoperative days were associated with poor prognosis (hazard ratio = 1.81; 95% CI: 1.09-3.06; p = 0.02).CONCLUSIONS: Surgical treatment of lung metastases is safe and effective, with good overall survival, especially in patients with fewer metastases.

Context The prognosis of appendiceal goblet cell carcinoid tumors (GCTs) is believed to be intermediate between appendiceal adenocarcinomas and conventional carcinoid tumors. However, GCTs can have mixed morphologic patterns, with variable amount of adenocarcinoma. Objective To evaluate the behavior of GCTs and related entities with variable components of adenocarcinoma. Design We classified 74 cases of appendiceal tumors into 3 groups: group 1, GCTs or GCTs with less than 25% adenocarcinoma; group 2, GCTs with 25% to 50% adenocarcinoma; group 3, GCTs with more than 50% adenocarcinoma; and a comparison group of 68 adenocarcinomas without a GCT component (group 4). Well-differentiated mucinous adenocarcinomas were excluded. Clinicopathologic features and follow-up were obtained from computerized medical records and the US Social Security Death Index. Results Of the 142 tumors studied, 23 tumors (16%) were classified as group 1; 27 (19%) as group 2; 24 (17%) as group 3; and 68 (48%) as group 4. Staging and survival differed significantly among these groups. Among 140 patients (99%) with available staging data, stages II, III, and IV were present in 87%, 4%, and 4% of patients in group 1 patients; 67%, 7%, and 22% of patients in group 2; 29%, 4%, and 67% of patients in group 3; and 19%, 6%, and 75% of patients in group 4, respectively (P = .01). Mean (SD) overall survival was 83.8 (34.6), 60.6 (30.3), 45.6 (39.7), and 33.6 (27.6) months for groups 1, 2, 3, and 4, respectively (P = .01). By multivariate analysis, only stage and tumor category were independent predictors of overall survival. Conclusion Our data highlight the importance of subclassifying the proportion of adenocarcinoma in appendiceal tumors with GCT morphology because that finding reflects disease stage and affects survival.

Abstract BACKGROUND Glioblastoma (GBM) is the most aggressive primary central nervous system malignancy. The median overall survival is 15 to 18 months with treatment and decreases to nine months after first progression. METHODS This is a retrospective study. Data was collected from all patients with first progression of GBM treated at CCF between Jan 2012 to Jan 2020. Eight cohorts of patients were evaluated: Group 1 received cytotoxic chemotherapy, Group 2 received bevacizumab alone, Group 3 received surgical or reirradiation alone, Group 4 were enrolled in clinical trials. Each group was divided into methylated and unmethylated cohorts. RESULTS Median overall survival was 12.4 months for patients with first progression of GBM (n= 248). Among the methlylated patients, the median overall survival was 16.5 months for group 1, 13.4 for group 2, 23.7 for group 3, and 17.3 for group 4. Among the unmethylated patients, the Median overall survival was 8.6 months for group 1, 7.7 months for group 2, 11.7 months for group 3 and 10.7 months for group 4. (p= 0.00016). Progression free survival (PFS) was 4.3 months for all patients with first progression of GBM. Among the unmethlylated patients, the PFS was 3.6 months for group 1, 15.3 months for group 2, 4.8 months for group 3, and 6.1 months for group 4. Among the unmethylated patients, the PFS was 2.3 months for group 1, 3.9 months for group 2, 3.8 months for group 3, and 4.4 months for group 4. (p &lt; 0.0001). CONCLUSION Patients with first progression of GBM had the best overall survival in the cohort that underwent a surgical or reirradiation. The best progression free survival was for patients who were treated with Bevacizumab if they were methylated and those enrolled in clinical trials if they were unmethylated. The study was statistically significant.

373 Background: Single hepatocellular carcinoma (HCC) regardless of size that without vascular invasion is classified as stage A disease in the Barcelona Clinic Liver Cancer staging system. However, patients with different tumor size may have different overall survival after hepatectomy. This study compared the prognosis of patients with single HCC after hepatectomy among groups with different tumor size. Methods: Patients with newly diagnosed single HCC from January 1, 2004 to October 31, 2013 were classified according to tumor size: group 1, ≤ 5 cm; group 2, > 5 cm and ≤ 8 cm; group 3, > 8 cm and < 10 cm; and group 4, ≥ 10 cm. Overall survival analysis was performed according to tumor size. Results: A total of 857 patients were enrolled. Among them, 814 (95.0%) were with Child-Pugh A class liver function. Blood loss was 367 ± 424 mL. Groups 1, 2, 3, and 4 consisted of 426 (49.7%), 229 (26.7%), 52 (6.1%), and 150 (17.5%) patients, respectively. The 5 years overall survival ranged from 35 to 63% in all four groups. The median survival time differed significantly according to tumor size (76, 49, 43, and 38 months in groups 1, 2, 3, and 4, respectively; P  <  0.001). Group 3 had overall similar survival to group 4. Multivariate analysis showed that group 3 and 4 had significantly worse overall survival compared to group 1 and 2. Conclusions: Patients in group 3 and 4 had significant worse prognosis than those in group 1 or group 2. Our results suggest that subset classification based on tumor size is warranted to patients’ prognosis.

e14526 Background: Glioblastoma (GBM) is the most common primary central nervous system malignancy, with a median overall survival of 14 to 17 months. First progression refers to progressive disease after initial radiation with or without chemotherapy. The median overall survival of patients with the first progression of GBM is nine months. Currently, there is no standard treatment for progressive GBM. Common treatment options include clinical trials, surgical resection, re-irradiation, stereotactic radiosurgery, cytotoxic chemotherapies, bevacizumab, and tumor treating fields. Methods: This retrospective study reviewed 244 patients with the first progression of GBM who were treated at CCF between Jan 2012 to Jan 2020. Statistical analyses included patients who had biopsy-proven GBM, a known MGMT methylation status, a KPS of more than 70 and presented with the first progression on MRI brain. Four cohorts of patients were evaluated: Group 1 received cytotoxic chemotherapy, Group 2 received bevacizumab alone, Group 3 received surgical or radiation therapy alone, Group 4 received experimental treatments. Results: The median overall survival (OS) and progression-free survival (PFS) was 12.4 months (95% CI: 10.9 to 14.3) and 4.3 months (95% CI: 3.9 to 5.4), respectively. The cohorts demonstrate statistical significant differentiation for PFS (p = 0.021) but not OS (p = 0.19). Second progression was noted at a median interval of 5.6 months in Group 4, 4.3 months in Group 2, 3.8 months Group 3 and 3.2 months in Group 1. Conclusions: Patients with the first progression of GBM had a better progression-free survival on experimental clinical trials than those in other cohorts.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

Background: We hypothesized that perioperative HbA1c influenced the pattern and outcomes of Lower Extremity Amputation (LEA). Methods: A retrospective analysis was conducted for all patients who underwent LEA between 2000 and 2013. Patients were categorized into 5 groups according to their perioperative HbA1c values [Group 1 (<6.5%), Group 2 (6.5-7.4%), Group 3 (7.5-8.4%), Group 4 (8.5-9.4%) and Group 5 (≥9.5%)]. We identified 848 patients with LEA; perioperative HbA1c levels were available in 547 cases (Group 1: 18.8%, Group 2: 17.7%, Group 3: 15.0%, Group 4: 13.5% and Group 5: 34.9%). Major amputation was performed in 35%, 32%, 22%, 10.8% and 13.6%, respectively. Results: The overall mortality was 36.5%; of that one quarter occurred during the index hospitalization. Mortality was higher in Group 1 (57.4%) compared with Groups 2-5 (46.9%, 38.3%, 36.1% and 31.2%, respectively, p=0.001). Cox regression analysis showed that poor glycemic control (Group 4 and 5) had lower risk of mortality post-LEA [hazard ratio 0.57 (95% CI 0.35-0.93) and hazard ratio 0.46 (95% CI 0.31-0.69)]; this mortality risk persisted even after adjustment for age and sex but was statistically insignificant. The rate of LEA was greater among poor glycemic control patients; however, the mortality was higher among patients with tight control. Conclusion: The effects of HbA1c on the immediate and long-term LEA outcomes and its therapeutic implications need further investigation.
