Stereotactic Radiosurgery for Differentiated Thyroid Cancer Brain Metastases: An International, Multicenter Study

xlomafota13 shared this article with you from Inoreader Message: Abstract Background: Brain metastases (BM) from differentiated thyroid cancer are rare. Stereotactic radiosurgery (SRS) is commonly used for the treatment of BMs; however, the experience with SRS for thyroid cancer BMs remains limited. The goal of this international, multi-centered study was to evaluate the efficacy and safety of SRS for thyroid cancer BMs. Methods: From 10 institutions participating in the International Radiosurgery Research Foundation, we pooled patients with established papillary or follicular thyroid cancer diagnosis who underwent SRS for histologically confirmed or radiologically suspected BMs. We investigated patient overall survival (OS), local tumor control, and adverse radiation events (AREs). Results: We studied 42 (52% men) patients who underwent SRS for 122 papillary (83%) or follicular (17%) thyroid cancer BMs. The mean age at SRS was 59.86 ± 12.69 years. The mean latency from thyroid cancer diagnosis to SRS for BMs was 89.05 ± 105.49 months. The median number of BMs per patient was 2 (range: 1–10 BMs). The median SRS treatment volume was 0.79 cm3 (range: 0.003–38.18 cm3), and the median SRS prescription dose was 20 Gy (range: 8–24 Gy). The median survival after SRS for BMs was 14 months (range: 3–58 months). The OS was significantly shorter in patients harboring ≥2 BMs, when compared with patients with one BM (Log-rank = 5.452, p = 0.02). Two or more BMs (odds ratio [OR] = 3.688; confidence interval [CI]: 1.143–11.904; p = 0.03) and lower Karnofsky performance score at the time of SRS (OR = 0.807; CI: 0.689–0.945; p = 0.008) were associated with shorter OS. During post-SRS imaging follow-up of 25.21 ± 30.49 mont hs, local failure (progression and/or radiation necrosis) of BMs treated with SRS was documented in five (4%) BMs at 7.2 ± 7.3 months after the SRS. At the last imaging follow-up, the majority of patients with available imaging data had stable intracranial disease (33%) or achieved complete (26%) or partial (24%) response. There were no clinical AREs. Post-SRS peritumoral T2/fluid attenuated inversion recovery signal hyperintensity was noted in 7% BMs. Conclusion: The SRS allows durable local control of papillary and follicular thyroid cancer BMs in the vast majority of patients. Higher number of BMs and worse functional status at the time of SRS are associated with shorter OS in patients with thyroid cancer BMs. The SRS is safe and is associated with a low risk of AREs.

Stapes Surgery in Far-Advanced Otosclerosis

xlomafota13 shared this article with you from Inoreader Stapes Surgery in Far-Advanced Otosclerosis Via ear nose throat Ear Nose Throat J. 2021 May 11:1455613211013093. doi: 10.1177/01455613211013093. Online ahead of print. ABSTRACT INTRODUCTION: Surgical treatment of patients with far-advanced otosclerosis (FAO) has not yet been standardized. Patients with FAO are the candidates for stapes surgery or cochlear implant (CI). Although many surgeons consider stapes surgery as the first choice, other authors prefer CI because of the excellent hearing results. OBJECTIVE: The authors discuss their experience in the treatment of patients with FAO, potentially candidates for CI, who underwent stapedotomy. MATERIALS AND METHODS: Eleven adult patients with FAO underwent stapedotomy from 2006 to 2016. Pure-tone average (PTA) between 0.5-1-2-3 kHz and speech perception test with hearing aids were determined before and after stapedotomy. RESULTS: The results show a statistically significant improvement in air condition threshold (PTA) and satisfactory results with regard to speech recognition in 9 (81.8%) cases. Postoperative results are not influenced by the type of stapedotomy prosthesis employed and do not change during follow-up (3 years). CONCLUSIONS: The authors suggest first performing stapes surgery in patients with FAO and reserving CI in case of failure. PMID:33971751 | DOI:10.1177/01455613211013093 View on the web Inoreader.

Online ahead of print. ABSTRACT Radiofrequency coblation is a new method of electrosurgical intervention. Most recently, its use has been reported in the treatment of laryngotracheal pathology. However, studies on coblation for tracheal tumors have not been reported. In this article, we described a novel use of coblation technology, in which a new type of airway-specific wand was used to ablate tracheal benign or malignant tumors in 3 cases. The results suggest the possibility of usage of coablation in the treatment of tracheal tumors. More studies that are larger and have longer follow-up are needed to further evaluate the use of this technique in the treatment of tracheal tumors.

Cancer predisposition syndromes

xlomafota13 shared this article with you from Inoreader Pediatric Head and Neck Tumors Associated with Li-Fraumeni Syndrome Via otol rhinol Ann Otol Rhinol Laryngol. 2021 May 10:34894211014786. doi: 10.1177/00034894211014786. Online ahead of print. ABSTRACT INTRODUCTION: Cancer predisposition syndromes are germline pathogenic variants in genes that greatly raise the risk of developing neoplastic diseases. One of the most well-known is Li-Fraumeni syndrome (LFS), which is due to pathogenic variants in the TP53 gene. Children with LFS have higher risks for multiple malignancies before adulthood, often with rare and aggressive subtypes. OBJECTIVE: To examine head and neck manifestations of LFS in children treated at a tertiary children's hospital over a 20-year period. METHODS: A retrospective review of LFS children with neoplastic disease presenting in traditional Otolaryngologic head and neck subsites from 2000 to 2019, with patient charts reviewed for relevant clinical, imaging, and operative data. RESULTS: Of the 40 LFS patients initially identified, 27 neoplastic tumors were identified in 20 children within this cohort (20 primary, 7 second primary). Head and neck subsites aside from the brain or orbit were involved in 22% (6/27) of these tumors, representing 20% (4/20) of primary tumors and 29% (2/7) of second primary tumors. Both second primaries within the head and neck were within the radiation fields of the first primary tumor. The mean ages at primary and second primary diagnosis were 4.6 years (SD 3.5) and 12 years (SD 1.4), respectively. The male/female r atio was 1:6 among all patients with head and neck tumors. All 6 head and neck tumors were sarcomas. Rhabdomyosarcoma (N = 3, 50%) was the most common pathology, and the other 3 demonstrated rare tumor pathological subtypes (synovial cell sarcoma, pleomorphic myxoid liposarcoma, mandibular osteosarcoma). The neck was the most common subsite (75%) within this group for primary tumor presentation. CONCLUSION: This study identifies a high potential for head and neck involvement in children with LFS, which has not been previously described in the literature. Otolaryngological care should be included in a multidisciplinary care team surveilling these patients. PMID:33971750 | DOI:10.1177/00034894211014786 View on the web Inoreader.

Auricular Perichondrium Graft for Septal Perforation Repair

xlomafota13 shared this article with you from Inoreader Auricular Perichondrium Graft for Septal Perforation Repair Via otol rhinol Ann Otol Rhinol Laryngol. 2021 May 10:34894211015738. doi: 10.1177/00034894211015738. Online ahead of print. ABSTRACT OBJECTIVES: Procedures which utilize bilateral mucosal flaps with an interposition graft are frequently used when attempting closure of a septal perforation. Concurrent surgical management of the nasal valve or an aesthetic deformity may be indicated. The objective of this study is to report our experience using auricular perichondrium for the interposition g raft when auricular cartilage is harvested for structural or aesthetic graft material. METHODS: A retrospective medical record review was performed for septal perforation repairs performed at Mayo Clinic in Arizona from January 2010 through January 2020. Patients identified for this study underwent a procedure utilizing bilateral nasal mucosal flaps with an auricular perichondrium interposition graft. RESULTS: Forty-four patients (31 females) with a mean age of 53.3 years met study criteria. The most common presenting symptoms were nasal obstruction, crusting, and epistaxis. Prior septal surgery was the most common perforation etiology (45.5%). Mean perforation length was 11.8 (range, 3-26) mm and height, 9.1 (range, 2-16) mm. Auricular cartilage was harvested for nasal valve surgery in 43 patients. Complete perforation closure was noted in 95.3% (41/43) of patients with a minimum post-operative follow-up of 3 (mean, 20.4) months. Four patients underwent revision surgery for persistent postoperative nasal obstruction. CONCLUSION: The ear can provide both cartilage and perichondrium for use in septal perforation surgery. Our study demonstrates the successful use of auricular perichondrium as the interposition graft for a perforation closure procedure utilizing bilateral nasal mucosal flaps.

Mapping the Risk Factors of Pharyngocutaneous Fistula After Salvage Laryngectomies

xlomafota13 shared this article with you from Inoreader Mapping the Risk Factors of Pharyngocutaneous Fistula After Salvage Laryngectomies Via Otolaryngology Indian Abstract To evaluate the postoperative surgical wound infection prevalence rates of patients undergoing SL, identify the causative organism and determine predisposing factors leading to infection. A retrospective study of all consecutive patients who underwent salvage total laryngectomy at our unit between 2015 and 2020 was performed. The following parameters were also analyzed: age, smoking history, pre and postoperative albumin level, history of radio and chemo-radiotherapy, reconstruction with pectoralis flap, intraoperative tracheoesophageal puncture, and tumor stage. A total of 12 of the 21 patients (57%) experienced a postoperative infection after SL during the study period. 82% of those patients whose preoperative albumin level below 3gm/dl developed postoperative infection. There is a significant increase (p < 0.01) in infection in patients with N1 and 2 stage tumor (68%) compared with the N0 stage tumors (40%). Multivariate analysis showed that preoperativ e albumin and nodal stage were significant risk factors for postoperative infection. View on the web Inoreader. Take back control of your news feed.
