OBJECTIVE The recurrence and progression of ameloblastoma are unpredictable. Therefore, we examined the influence of clinical factors on recurrence time and analyzed the clinical factors associated with early recurrence and cancerization. We then developed a staging system to predict early recurrence and cancerization. METHODS All of the primary craniofacial ameloblastoma patients treated in ...

BACKGROUND We evaluated the clinical outcome of low grade Ta bladder cancer followed-up for a long period using the 2004 WHO grading system. METHODS We retrospectively reviewed 190 patients with primary, low grade Ta bladder cancer. We defined worsening progression (WP) as confirmed high grade Ta, all T1 or Tis/concomitant CIS of bladder recurrence, upper urinary tract recurrence (UTR), or pr...

 Abstract  Background: Resection of the distal end of the radius is indicated in the treatment  of locally aggressive primary benign and malignant bone tumors. The aim of this study  was to evaluate the technique of osteoarticular allograft reconstruction of the distal radius after wide excision of a giant-cell tumor.  Methods: We analyzed 15 patients retrospectively who had reconstruction of t...

Carbon dioxide (CO2) laser surgery as a conservative tool plays a peculiar role in the management of head and neck cancer. Numerous patients who were candidates for transoral laryngeal microsurgery have forced us to eliminate frozen-section evaluation of surgical margins and use a magnified view of the larynx. The present study evaluated surgeon-judged negative margins with permanent microscopi...

introduction: ameloblastic fibro-odontoma is a rare, benign, asymptomatic tumor. the term ameloblastic fibro-odontoma was first used by hooker in 1967 as a separate lesion from ameloblastic odontoma.   case report: this case report describes an eleven years old female with large ameloblastic fibro-odontoma in the right maxillary sinus.   conclusion: there is a low potential for recurrence after...

BACKGROUND AND OBJECTIVES Thymoma has a variable long-term oncological outcome after surgical resection. Survival and tumor recurrence were analyzed to determine the predisposing factors for tumor recurrence. METHODS A total of 235 patients who underwent surgery for thymoma or thymic carcinoma from December 1997 to March 2013 were analyzed using Masaoka staging system and World Health Organiz...

BACKGROUND The recurrence of pleomorphic adenoma (PA) has been extensively debated, mostly in relation to the extent of parotidectomy. METHODS A systematic review was undertaken to clarify the surgical and pathological variables related to PA recurrence. Inclusion criteria were as follows: English literature, and prospective or retrospective studies. Exclusion criteria were as follows: single...

PURPOSE To classify ipsilateral in-breast cancer recurrences (IBCR) in patients treated with conservative surgery and radiation therapy, either as new primary tumor (NP) or true recurrence (TR) and to assess the prognostic and therapeutic importance of this classification. METHODS The records of 107 patients treated for local tu- mor recurrence after breast-conserving therapy (BCT) at the Nat...
