The scheduled combined treatment (surgery plus IOBRT) was possible to perform in 66% of RSTS cases that received surgical treatment. The complication rate was high, but we consider it acceptable because of the necessity for extensive aggressive surgical treatment in regionally advanced RSTS. EBRT seems to be an indispensable part of treatment that provides better local control.
Purpose: Adenoid cystic carcinoma (ACC) of trachea is a relatively rare malignant neoplasm, for which there is a lack of prospective clinical trials investigating treatment effectiveness. Most of the authors prefer surgical resection followed by post-operative radiation therapy in case of incomplete excision. There are no available prospective data on post-relapse treatment.Case presentation: The current paper presents a case of tracheal ACC in a young woman, treated solely with surgical resection without radiotherapy due to postoperative neurological complications requiring additional diagnostics, management, and treatment. As a complication itself, spinal cord dysfunction after tracheal surgery is extremely rare, in which radical radiotherapy and brachytherapy were successfully administered after disease recurrence.Conclusions: Lack of post-operative radiotherapy resulting from neurological complications could be a reason for ACC recurrence in our patient. Administration of radiotherapy after incomplete resection of recurrent disease may lead to long-term locoregional control.
PurposeThe primary aim of this work was to analyze feasibility of combined treatment of retroperitoneal sarcomas (RS): surgery (S) and intraoperative brachytherapy (IOBRT). The secondary aim was to analyze results and complications after this treatment.Material and methods84 patients with retroperitoneal sarcomas were qualified for combined treatment (S and IOBRT) between June 1998 and September 2006. 65 of the patients (77.4%) had local recurrences. Sarcomas with intermediate and high grade of histological malignancy (G2, G3 – 76.2%) were the most frequent within the all surgically treated patients. Resection ability (R0/R1) in analyzed group of patients was estimated as 85% (74 cases). After intraoperative evaluation, 57 (67.8%) patients were qualified for IOBRT. Since 2000, in 34 patients (60%) an adjuvant postoperative external beam radiation therapy (EBRT) in dose of 50 Gy was applied. Median follow-up of the surviving patients was 40 months.ResultsOn the basis of the univariate analysis, relevant aspects negatively influencing overall survival rate within the RS group treated with IOBRT were as follows: surgery of sarcoma recurrence (p = 0.002), higher grade of histological malignancy (p = 0.05), histological type different than liposarcoma (p = 0.05) as well as no adjuvant EBRT (p = 0.05). On the basis of multivariate analysis one can ascertain that relevant factors negatively influencing LRFS in RS patients treated with IOBRT were: surgery due to recurrence of sarcoma (p = 0.008) and lack of EBRT (p = 0.01).ConclusionsCombined treatment (surgery and brachytherapy) was possible to be carried out on 68% of RS patients. The overall number of complications was quite high, however acceptable, taking into consideration the application of extensive, multi-organ treatments in case of sarcoma recurrences in this localization. The results suggest that the method of treatment will improve the final outcome when most of patients will be qualified for treatment of primary sarcomas in experienced centre.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
