Venous thromboembolism after adult thymus or thymic tumor resection: A single‐center experience

e15747 Background: Surgical resection of PAC followed by adjuvant therapy is the standard of care for non-metastatic resectable tumors. Surgical resection with clear margins of borderline (BR) or locally advanced (LA) tumors is either challenging or impossible. Furthermore, there are no clear recommendations concerning NAT for non-upfront resectable PAC. Thus we reviewed our own experience with different NAT modalities for BR and LA PAC. Methods: Medical records of patients identified by Tumor Board as BR or LA PAC and treated with NAT at Centre Hospitalier de l’Université de Montréal (CHUM) were retrospectively reviewed. Survival curves were estimated by the Kaplan-Meier method and compared with the Log-rank test. For both univariate and subgroup analyses, hazard ratio and 95% confidence interval were estimated by Cox proportional hazard regression. Results: Between 2009 and 2017, 90 patients (50 BR, 40 LA) were identified. Chemotherapy, mostly FOLFIRINOX, was the only NAT in 51 patients (56.6%), 23 patients (25.3%) received chemoradiotherapy alone and 16 patients (17.7%) received sequential treatment of both modalities. Tumor resection was achieved in 44 patients, with 32 BR patients (R0: 68.7%) and 12 LA patients (R0: 75%). Median Disease free survival (DFS) of patients that underwent resection was 12.3 months. mPFS was 29 vs 10 months (HR:0.2; p < 0.001) and mOS was 41.7 vs 15.7 months (HR:0.3; p < 0.001) in resected and non-resected patients, respectively. In subgroup analysis, resection statistically improved PFS and OS regardless of age, sex, T stage and type of vessel involvement. Treatment with more than one modality showed better clinical outcomes (PFS and OS) and a non-statistically higher R0 resection rate that was 100% in BR tumors. OS in patients with resected cancers was not reached for the multimodality group, 41.7 months for chemotherapy alone group and 22.4 months in patients treated with chemoradiotherapy group (p = 0.017). Conclusions: In this retrospective single center analysis, NAT with chemotherapy and/or chemoradiotherapy appears to improve patients’ clinical resection results and outcomes. These results validate previous retrospective studies but warrant large prospective trials to define the best NAT.

Single Center Experience

Reconstructive surgery following skin tumor resection can be challenging. Treatment options after removing the tumor are skin grafting, local pedicled and axial flaps, or microsurgery for complex and extensive wounds correction. Recently, the use of dermal substitutes has been extended to reconstructive surgery in cutaneous oncology. Objectives. To report both a single-center experience using dermal substitutes in reconstructive surgery for skin malignancies and reconstructive surgery’s outcomes. Methods and Results. Among thirteen patients, seven (53.8%) were male with mean age of 62.6 years. Regarding diagnosis, there were five cases (38.5%) of basal cell carcinoma (BCC), two (15.4%) of melanoma in situ, two (15.4%) of dermatofibrosarcoma protuberans, one (7.7%) of squamous cell carcinoma (SCC), one (7.7%) of angiosarcoma, and one (7.7%) of eccrine carcinoma (EC). The most common site of injury was scalp (53.8%) and lower limbs (23.1%). Seven (53.8%) patients used NPWT and six (46.2%) patients underwent Brown’s dressing. The most frequent complication of the first stage was wound contamination (38.5%). Average time to second-stage skin grafting was 43.9 days. Three (23%) patients developed tumor recurrence and one died. Conclusions. Use of dermal substitutes in oncology can be an option for reconstruction after extended resections, providing good aesthetical and functional results.
