139 Background: There are several accepted peri-operative treatment modalities for resected gastric (GC) and gastroesophageal junction (GEJ) adenocarcinoma. In 2008, peri-operative chemotherapy (CT) using the MAGIC protocol was adopted as the preferred approach over adjuvant chemoradiation with the MacDonald protocol (cXRT) in British Columbia. An era to era comparison was performed to determine if there were differences in outcomes. Methods: Data from pharmacy records of patients (pts) referred to 1 of 5 cancer treatment centres in BC were analyzed from Jan 2001-July 2010. Pts that underwent curative resection for GC or GEJ were included. The cXRT cohort was defined as those treated from Jan 2001-Dec 2007, prior to the introduction of CT. The CT cohort included those treated from Jan 2008-July 2010. Descriptive statistics were used to compare the groups. Survival analysis was performed using Kaplan Meier methods. Results: Table 1 summarizes the patient characteristics. In the CT arm, there were more males, fewer pts with a LN ratio >0.2, and shorter median follow-up. 92.1% completed pre-operative chemotherapy and 44.7% completed post-operative chemotherapy whereas 73.3% of pts completed cXRT (p<0.05). Median survival was 37.5 and 36.9 months in the CT and cXRT arms, respectively. Conclusions: Delivery of CT was consistent with the MAGIC trial whereas more patients completed cXRT than in the MacDonald trial (73.3% vs. 64%). Outcomes of CT compared to cXRT appear to be similar in this comparative analysis with similar relapse and survival rates. Pre-operative CT results in fewer pts with a LN ratio > 0.2. Either modality can be considered in the peri-operative management of GC or GEJ adenocarcinoma. [Table: see text]

e14537 Background: Currently there are several accepted peri-operative treatment modalities for the resected gastric (GC) and gastroesophageal junction (GEJ) adenocarcinoma. In the 2008, peri-operative chemotherapy (CRT) using the MAGIC was adopted as the preferred approach to adjuvant chemoradiation with the MacDonald protocol (cXRT) in the British Columbia. An era to era comparison was performed to determine if there were differences in outcomes. Methods: Data from the pharmacy records of patients (pts) referred to 1 of 5 cancer treatment in BC were analyzed from 2001- July 2010. Pts that underwent curative resection for GC or GEJ were only included. cXRT cohort was defined from Jan 2001-Dec 2007, prior to the CRT era. CRT cohort started from Jan 2008-July 2010. Descriptive statistics were used to compare the groups. Survival analysis was performed using Kaplan Meier methods. Results: Table 1 summarizes the patient characteristics. In the CRT arm, there were more males, less pts with a LN ratio >0.2 and shorter median follow-up. 92.1% completed the pre-op chemotherapy and 44.7% completed post-op chemotherapy whereas 73.3% of pts completed cXRT (p<0.05). 1 yr survival was similar between the 2 cohorts. Median overall survival was not reached in the CRT arm and was 64.1 months in the cXRT arm. Conclusions: Delivery of CRT was similar to that in the MAGIC trial. Outcomes of CRT compared to cXRT appears to be similar in this cohort to cohort study with similar 1 yr survival. Pre-operative CRT results in less pts with a LN ratio > 0.2. Further follow-up is needed with respect to relapse and overall survival. Either modality can be considered for peri-operative management of GC or GEJ adenocarcinoma. [Table: see text]

Abstract Background: Diffuse large B-cell lymphoma (DLBCL) of the sinonasal track (SNT) is a rare presentation of the aggressive lymphoid malignancy with the incidence of 0.06-0.17 per 100 000 in the Western population. SNT involvement is associated with increased risk of central nervous system (CNS) progression, and thus eligible patients are often treated with chemoimmunotherapy in combination with CNS prophylaxis with intrathecally (it) or intravenously (iv) administered methotrexate (MTX). However, the data demonstrating that the addition of CD20 antibody rituximab and/or CNS penetrating MTX improves the outcome of the patients with SNT-DLBCL are lacking. Materials and Methods: The aim of the study was to characterize the clinical findings of the patients with SNT-DLBCL treated at two University Hospital districts in Finland (Helsinki and Tampere University Hospitals). The hospital records of 59 patients were retrospectively reviewed on parameters for patient demographics, tumor characteristics, treatment and outcome. Results: Forty-five patients were treated with curative intent with CHOP-like chemotherapy, 24 (53%) of them with chemoimmunotherapy containing rituximab (R+) and 21 (47%) before the rituximab era (R-). Among the patients treated with curative intent, iv MTX was given to 24 patients (53%; M+ group), whereas the remaining 21 patients (47%) did not receive MTX (M- group). The median age was 65 years for the whole cohort, and 64 years for the patients treated with curative intent. The patients treated with curative intent had better performance status in comparison to all patients. Otherwise, the patient characteristics were similar. Follow-up data was collected to 60 months. Median follow-up time for the entire cohort was 47 months. No differences were observed in the patient characteristics between the R+ and R- groups. The patients in the M+ group were younger than the patients in the M- group (67% vs 24% were <60 years, p=0.007). Otherwise, no significant differences in the patient characteristics were found between the two groups. MTX was used equally often during the pre-R and R eras. The patients in the R+ group had lower risk of progression (RR 0.384, 95% CI 0.145-1.018, p=0.054) and death (RR 0.235, 95% CI 0.066-0.836, p=0.025) in comparison to the patients in the R- group. According to Kaplan-Meier analyses, the patients in the R+ group had better survival rates than the patients in the R- group (5-y progression free survival (PFS) 66% vs 38%, p=0.046; 5-y overall survival (OS) 80% vs 43%, p=0.015). Addition of MTX to chemotherapy also reduced the risk of progression (RR 0.384, 95% CI 0.151-0.977, p=0.044) and death (RR 0.253, 95% CI 0.080-0.795, p=0.019). According to Kaplan-Meier analyses, the patients in the M+ group had better survival rates than the patients in the M- group (5-y PFS, 67% vs 31%, p=0.036; 5-y OS 82% vs 35%, p=0.011). Only one patient in the cohort experienced CNS progression. Conclusions: SNT-DLBCL patients treated with curative intent with R containing regimen have superior survival in comparison to the patients treated in the pre-R era. Likewise, intravenously administered CNS penetrating MTX improves survival. In this cohort, only one patient experienced CNS progression, and thus the impact of different treatments on the risk of CNS progression could not be evaluated.

Abstract OBJECTIVE Hemangiopericytomas are highly aggressive meningeal tumors with tendencies for recurrence and metastasis. The purpose of this retrospective, single-institution review was to evaluate the efficacy and role of stereotactic radiosurgery in the management of recurrent hemangiopericytomas. METHODS We reviewed data for patients who underwent stereotactic radiosurgery at the University of Pittsburgh between 1987 and 2001. Fourteen patients underwent radiosurgery for 15 discrete tumors. Prior treatments included transsphenoidal resection (n = 1), craniotomy and resection (n = 27), embolization (n = 1), and conventional radiotherapy (n = 7). Clinical and radiological responses were evaluated. Follow-up periods varied from 5 to 76 months (mean, 31.3 mo; median, 21 mo). The mean radiation dose to the tumor margin was 15 Gy. RESULTS Seventy-nine percent of patients (11 of 14 patients) with recurrent hemangiopericytomas demonstrated local tumor control after radiosurgery. Twelve of 15 tumors (i.e., 80%) dramatically decreased in size on follow-up imaging scans. Regional intracranial recurrences were retreated with radiosurgery for two patients (i.e., 15%); neither of those two patients experienced long-term tumor control. Local recurrences occurred 12 to 75 months (median, 21 mo) after radiosurgery. Local tumor control and survival rates at 5 years after radiosurgery were 76 and 100%, respectively (Kaplan-Meier method). We could not correlate prior irradiation or tumor size with tumor control. Twenty-nine percent of the patients (4 of 14 patients) developed remote metastases. Radiosurgery did not seem to offer protection against the development of intra- or extracranial metastases. CONCLUSION Gamma knife radiosurgery provided local tumor control for 80% of recurrent hemangiopericytomas. When residual tumor is identified after resection or radiotherapy, early radiosurgery should be considered as a feasible treatment modality. Despite local tumor control, patients are still at risk for distant metastasis. Diligent clinical and radiological follow-up monitoring is necessary.

Abstract Background The objective of this study was to evaluate the overall outcomes and complications of transvaginal mesh (TVM) placement for the management of pelvic organ prolapse (POP) with different meshes with a greater than 10-years of follow-up. Methods We performed a retrospective review of patients with POP who underwent prolapse repair surgery with placement of transvaginal mesh (Prolift kit or self-cut Gynemesh) between January 2005 and December 2010. Baseline of patient characteristics were collected from the patients’ medical records. During follow-up, the anatomical outcomes were evaluated using the POP Quantification system, and the Patient Global Impression of Improvement (PGI-I) was used to assess the response of a condition to therapy. Overall postoperative satisfaction was assessed by the following question: “What is your overall postoperative satisfaction, on a scale from 0 to 10?”. Relapse-free survival was analyzed using Kaplan–Meier curves. Results In total, 134 patients were included. With a median 12-year (range 10–15) follow-up, 52 patients (38.8%) underwent TVM surgery with Prolift, and Gynemesh was used 82 (61.2%). 91% patients felt that POP symptom improved based on the PGI-I scores, and most satisfied after operation. The recurrence rates of anterior, apical and posterior compartment prolapse were 5.2%, 5.2%, and 2.2%, respectively. No significant differences in POP recurrence, mesh-associated complications and urinary incontinence were noted between TVM surgery with Prolift versus Gynemesh. Conclusions Treatment of POP by TVM surgery exhibited long-term effectiveness with acceptable morbidity. The outcomes of the mesh kit were the same as those for self-cutmesh.

Background: With the emergence of the COVID-19 pandemic, most health-care personnel and resources are redirected to prioritize care for seriously-ill COVID patients. This situation may poorly impact our capacity to care for critically injured patients. We need to devise a strategy to provide rational and essential care to hand trauma victims whilst the access to theatres and anaesthetic support is limited. Our center is a level 1 trauma center, where the pandemic preparedness required reorganization of the trauma services. We aim to summarise the clinical profile and management of these patients and highlight, how we modified our practice to optimize their care. Methods: This is a single-centre retrospective observational study of all patients with hand injuries visiting the Department of Plastic Surgery from 22nd March to 31st May 2020. Patient characteristics, management details, and outcomes were analysed. Results: A total of 102 hand injuries were encountered. Five patients were COVID-19 positive. The mean age was 28.9 ± 14.8 years and eighty-two (80.4%) were males. Thirty-one injuries involved fractures/dislocations, of which 23 (74.2%) were managed non-operatively. Seventy-five (73.5%) patients underwent wound wash or procedure under local anaesthetic and were discharged as soon as they were comfortable. Seventeen cases performed under brachial-plexus block, were discharged within 24 hours except four cases of finger replantation/ revascularisation and one flap cover which were discharged after monitoring for four days. At mean follow-up of 54.4 ± 21.8 days, the rates of early complication and loss to follow-up were 6.9% and 12.7% respectively. Conclusions: Essential trauma care needs to continue keeping in mind, rational use of resources while ensuring safety of the patients and health-care professionals. We need to be flexible and dynamic in our approach, by utilising teleconsultation, non-operative management, and regional anaesthesia wherever feasible.

Background: Although highly positive results for wear reduction of highly cross-linked polyethylene (HXLPE) have been reported around the 10-year follow-up, the long-term result related to reoperation and wear-related survival is still an issue. Therefore, this study aimed to compare the follow-up results of a single manufacture’s polyethylene liner for >15 years in terms of survival and wear rate. Methods: This retrospective cohort study included 134 primary total hip arthroplasties (THAs) who were followed up for at least 15 years. The mean age at the time of surgery was 50.7 years (conventional polyethylene [CPE] group = 22; HXLPE group = 112). Linear and volumetric wear rates of polyethylene were measured, and the reoperation rate and radiographic osteolysis were evaluated and Kaplan-Meier survival analysis was performed in both groups. Implant-related complications were also examined. Results: HXLPE group showed a significantly lower wear rate in both linear and volumetric wear. None of the hip radiographs showed evidence of loosening or osteolysis in the HXLPE group. The survival rates at 15- to 18-year follow-up were 90.9% and 95.5% in the CPE and HXLPE groups when all-cause reoperation was the endpoint, and 90.9% and 100.0% when the wear-related reoperation was the endpoint, respectively. Implant-related complications were not different between the 2 groups. Conclusions: Wear reduction and osteolysis showed a great advantage in HXLPE after a 15-year follow-up. Although the CPE and HXLPE showed excellent survival, wear and osteolysis were more frequent in the CPE; therefore, the high risk of reoperation in the future should be considered.

Background. We studied whether heterogeneous profiles of cognitive function are relevant to survival in patients with early Alzheimer's disease.Methods. CAMCOG subscales of cognitive function were used as predictors of survival, together with gender in 157 consecutively referred patients with early Alzheimer's disease. Statistical analysis was performed with Cox proportional hazards analysis and Kaplan–Meier survival curves. Survival rates were compared with those in the general population.Results. Eighty patients (51%) died during the follow-up that extended to 5·7 years, with a median survival of 4·4 years after entry. Only the praxis subscore was statistically significant related to survival (P<0·0001). Its predictive power was based on only two items, including copying ability for a spiral and a three-dimensional house, independent of age, sex, education, overall CAMCOG score, dementia severity and symptom duration. Kaplan–Meier curves for the combined score of these items (0, 1, or 2) showed three groups with significantly different survival rates for both men and women. Comparison of gender specific survival rates with data from the general population showed that excess mortality was statistically significant (P<0·01) higher in men (51%) than in women (21%) after follow-up extending to 5 years.Conclusions. A simple test of copying ability defines subgroups of AD patients with large differences in survival rates. This suggests that parietal lobe impairment is an important predictor of mortality in AD. Also, the course of AD may be more benign in women than in men.

Aim. This study aimed to retrospectively compare the survival outcomes over two years between teeth with proximal dental caries that were restored with stainless-steel crowns to those that were pulpotomized and then restored with a stainless-steel crown in patients who were rehabilitated under general anesthesia. Participants and Methods. The records of 131 patients aged between two to six years who had stainless-steel crowns placed under general anesthesia and had two-year follow-up were screened. 340 teeth with moderate proximal caries on the radiograph (D2) were included in the study. Of these, 164 teeth were treated with a pulpotomy and stainless-steel crown, while 176 teeth were crowned without a pulpotomy. The type of each tooth was compared using the Chi-squared test and Kaplan–Meier survival analysis, and curves were plotted based on the two-year outcomes. Results. Treatment: the sample comprised 59 males (mean age 4.73 years, SD ± 1.4 years) and 72 females (mean age 5.2 years, SD ± 2.0 years). The Kaplan–Meier regression model showed no significant difference in survival outcomes between teeth that had been pulpotomized and those that had not ( p  = 0.283). Conclusion. Within the limitations of the current study, we can conclude that performing a pulpotomy does not influence the survival outcome of mild/moderate proximal caries restored with stainless-steel crowns under general anesthesia.

In this retrospective study, we analysed the long-term oncological and functional results after extended ray resection for sarcoma of the hand. Recurrence-free and overall survivals were calculated using the Kaplan–Meier method. The function of the operated hand was assessed with the Michigan Hand Questionnaire and compared with the contralateral side. Extended ray resection was performed in 25 out of 168 consecutive patients with soft-tissue and bony sarcomas of the hand. The overall 5- and 10-year, disease-specific survival rates were 86% and 81%, respectively. Local recurrences were observed in two patients. The Michigan Hand Questionnaire score for the affected hand at follow-up in nine patients was 82 points versus 95 for the healthy contralateral hands. We conclude that extended ray resection of osseous sarcomas breaking through the bone into the soft tissue or for soft tissue sarcomas invading bone is a preferable alternative to hand ablation when excision can be achieved with tumour-free margins. Level of evidence: III
