Abstract
OBJECTIVE Skull base osteosarcoma is a rare and aggressive tumor that is most commonly treated with primary surgical resection and adjuvant chemoradiation. Using the National Cancer Database, we analyzed demographic and clinical prognosticators for overall survival (OS). METHODS The National Cancer Database was queried for cases of histologically confirmed skull base osteosarcoma treated between 2004 and 2015, excluding patients receiving palliation or having <1 month of follow-up. A total of 314 patients treated with surgery alone (n = 82), surgery with adjuvant radiotherapy (n = 35), surgery with chemotherapy (n = 114), or trimodality therapy (n = 56) were identified. The χ2 test for categorical variables, Cox proportional hazards models, and Kaplan-Meier log-rank analysis were used to test associations with treatment, OS, and survival time. RESULTS None of the studied demographic characteristics (age, sex, race, overall health) and socioeconomic factors (income and average regional education) were associated with OS (none P < 0.05). Treatment modalities also did not show a significant association with OS (none P < 0.05). Certain tumor characteristics showed an association with OS, with fibroblastic and Paget histologic subtypes (each P = 0.003), poorly differentiated tumor grade (P = 0.03), and tumor size >5 cm (P = 0.045) associated with poorer OS. CONCLUSIONS Tumor histologic subtype, advanced tumor grade, and greater tumor size are predictors of worse OS in skull base osteosarcoma. No significant differences in OS were identified based on treatment modality, which warrants further investigation.

Funakoshi Y, Shono T, Kurogi A, Kono S. Osteosarcoma of the temporal bone occurring 40 years after radiotherapy: A technical case report presenting en bloc resection of intra- and extracranial lesions followed by a one-stage reconstruction. Surg Neurol Int 2021; 12:152. [PMID: 33948322 PMCID: PMC8088493 DOI: 10.25259/sni_857_2020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Accepted: 03/03/2021] [Indexed: 01/25/2023] Open
Abstract
Background: Osteosarcoma (OS) is a malignant tumor of the bone, which rarely occurs in the head-and-neck regions as a primary or a secondary malignancy. Adequate surgical resection is currently the mainstay of treatment for head-and-neck OS; however, en bloc resection and reconstruction can be difficult because the anatomies of these regions are complex. We present a case of an OS arising from the temporal bone 40 years after radiation therapy, which was successfully treated with en bloc resection and a one-stage reconstruction using intraoperative tissue expansion technique. Case Description: A 62-year-old woman who underwent surgery and radiotherapy for a left temporal lesion 40 years before presentation was hospitalized for aphasia and a right hemiparesis. She had a 4 × 3 cm subcutaneous mass in the left temporal area of the head. Computed tomography imaging showed destruction of the left temporal bone and a partially calcified mass. Magnetic resonance imaging showed an enhancing mass with intracranial and extracranial cystic components (5 cm and 3 cm in diameter, respectively). Due to rapid growth of the lesion, a semi-urgent surgery was performed. In this operation, a continuous narrow craniectomy was performed around the tumor using a ruler. Then, en bloc resection of the tumor, with adjacent skin, temporal muscle, skull, dura mater, and cerebral cortex, was achieved. Subsequently, a one-stage reconstruction of the dura mater, skull, and skin of the head was performed using fascia lata, artificial bone, and a local skin flap combined with intraoperative tissue expansion using a 20-French Foley catheter. Postoperative histological examinations revealed the tumor to be an OS. Conclusion: We have presented a rare case of an OS occurring from the temporal bone 40 years after radiation therapy. We describe our experience and the surgical methods in this case to provide options for surgical strategies in patients with head-and-neck OS.

Ocular surface squamous neoplasia: outcomes following primary excision with 2 mm margin and cryotherapy. Eye (Lond) 2021; 35:3102-3109. [PMID: 33469127 DOI: 10.1038/s41433-020-01353-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Revised: 11/25/2020] [Accepted: 11/27/2020] [Indexed: 11/08/2022] Open
Abstract
PURPOSE To assess margins and the rate of local recurrence of ocular surface squamous neoplasia after excision with a 2 mm margin and cryotherapy at a single ophthalmic oncology center. OUTCOME MEASURES (1) Conjunctival margin were assessed as positive, negative, or indeterminate margins. (2) Feasibility of repair without a graft. (3) Local recurrence. METHODS Retrospective chart review of histologically proven conjunctival intraepithelial neoplasia and invasive squamous cell carcinoma cases that underwent excision with a 2 mm margin and cryotherapy. RESULTS Eighty cases met inclusion criteria for the quantitative analysis. The margin was positive in six cases (7.5%), four of which were treated with post-op topical immunotherapy/chemotherapy. Of the six positive margin cases, there was one recurrence which occurred in the patient who did not receive post-op topical adjuvant therapy, however resolved after starting topical treatment. Conjunctival repair without use of a graft was feasible in 74 (93%) cases with a mean basal diameter of 6.4 mm. Total number of local recurrence was seen in three cases (4%), which were successfully treated with adjuvant topical treatment (one positive margin case, one indeterminate margin case) or repeat resection followed by episcleral plaque brachytherapy (one negative margin case). CONCLUSION Excision with 2 mm margin of OSSN is not associated with high rates of positive surgical margins. Even those with positive margins, when treated with adjuvant topical therapy did not develop recurrence. While achieving low rates of local recurrence, the conjunctiva is conserved, thereby minimizing the need for amniotic membrane or free conjunctival grafts for conjunctival repair.

Abstract
OBJECTIVE The aim of the study was to characterize the epidemiology and treatment outcomes of head and neck (HN) osseous-site tumors. METHODS Descriptive analyses and multivariate Cox regressions were performed to analyze the effect of surgery on overall survival (OS) utilizing the National Cancer Database (2004-2016). RESULTS Of 2449 tumors, surgery was utilized in 84.5% of cases. OS was worse in osteosarcoma (5-year OS: 53.4% [SE: 2.5%]) compared with cartilage tumors (5-year OS: 84.6% [SE: 1.8%]) (log-rank P < .001). Treatment regimens that included surgery were associated with improved OS on multivariate analysis (hazard ratio [HR] 0.495 [95% CI: 0.366-0.670]). Positive margins were found in 40.8% of cases, and associated with decreased OS in osteosarcomas (HR 1.304 [0.697-2.438]). CONCLUSION Treatment that included surgery was associated with an increased OS within our cohort of HN osseous-site tumors, although the rates of positive margins were >40%. These findings may be limited by inherent selection bias in the database.

Abstract
Skull base primary malignancies represent a heterogeneous group of histologic diagnoses and sarcomas of the skull base are specific malignant tumors that arise from mesenchymal cells and can be classified by site of origin into bony and soft tissue sarcomas. The most common bony sarcomas include: chondrosarcoma, osteosarcoma, chordoma, Ewing's sarcoma. Given the relative rarity of each histologic diagnosis, especially in the skull base, there is limited published data to guide the management of patients with skull base sarcomas. An electronic search of the literature was performed to obtain key publications in the management of bony sarcomas of the skull base published within the last decade. This article is thus a review of the multi-disciplinary management principles of primary bony sarcomas of the skull base. Of note, there have been several recent advancements in the realm of skull base sarcoma management that have resulted in improved survival. These include advances in: imaging and diagnostic techniques, surgical techniques that incorporate oncologic surgical principles, conformal radiation paradigms and targeted systemic therapies. Early access to coordinated multi-disciplinary subspecialty care immediately at suspicion of diagnosis has further improved outcomes. There are several ongoing trials in the realms of radiation therapy and systemic therapy that will hopefully provide further insight about the optimal management of bony sarcomas of the skull base.

Custom-Made Porous Hydroxyapatite Cranioplasty in Patients with Tumor Versus Traumatic Brain Injury: A Single-Center Case Series. World Neurosurg 2020; 138:e922-e929. [PMID: 32272268 DOI: 10.1016/j.wneu.2020.03.144] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 03/23/2020] [Accepted: 03/24/2020] [Indexed: 01/07/2023]
Abstract
BACKGROUND Cranioplasty is a common neurosurgical procedure with the goal of restoring skull integrity. Custom-made porous hydroxyapatite prostheses have long been used for cranial reconstruction in patients with traumatic brain injury. We present a large consecutive series of 2 groups of patients undergoing cranioplasty with hydroxyapatite custom bone and compare the adverse events (AEs) between the 2 groups. METHODS We examined a series of consecutive patients who underwent cranioplasty using custom-made porous hydroxyapatite implants following tumor resection and traumatic brain injury at a single center between March 2003 and May 2018. The implants were designed and produced according to the surgeon's specifications and based on the patient's computed tomography scan data obtained through a standardized protocol. AEs were recorded. RESULTS Information on 38 patients with tumor and 39 patients with traumatic brain injury was collected and analyzed. A significant difference in the timing of surgery was found between the 2 groups; single-stage surgery was performed in 84% of patients in the tumor versus 8% of those in the traumatic brain injury group (P < 0.0001). The rate of AEs was not significantly different between the 2 groups (P = 0.4309) and was not related to the timing of surgery. CONCLUSIONS Custom-made hydroxyapatite cranioplasty is a solution for cranial reconstruction in patients with cranial tumors. The low incidence of AEs in a consecutive series of patients with either trauma or tumors demonstrates that these prostheses represent a safe solution independent of the characteristics of cases.
