Local recurrence of rectal cancer is the result either of potentially removable tumor cells left in situ or cells already disseminated to areas where surgery cannot reach them. The first scenario infers inadequate surgery, the second implies unfavorable biology. Surgeons who operate for rectal cancer must know local recurrence rates in their patients, and be able to relate them to outcomes achi...

OBJECTIVES/HYPOTHESIS To identify factors contributing to local tumor recurrence in oral cavity and laryngeal squamous cell carcinomas treated with surgery alone, to approximate tumor age from time to recurrence data by applying Collins' law, and to identify factors that may affect time to recurrence. STUDY DESIGN Retrospective review. METHODS A retrospective review of all patients treated ...

PURPOSE The identification of colon cancer patients at high risk of local recurrence is necessary to improve the selection of patients for more tailored treatment protocols. The aim of this study was to develop a predictive model of local recurrence by assessing the independent predictive effect of 7 clinicopathologic features, 24 protein markers of tumor progression, and their multifeature com...

BACKGROUND Dermatofibrosarcoma protuberans (DFSP), a rare low-grade sarcoma of fibroblast origin, tends to extend in a finger-like fashion beyond macroscopic tumor margins. Therefore, incomplete removal and subsequent recurrence are common. This study aimed to determine the efficacy of wide local excision (WLE) for controlling local recurrence of DFSP. METHODS The medical records of 90 DFSP p...

Desmoid tumor is a rare soft tissue and accounts less than 1% of retroperitoneal tumor. It pathologically benign tumor, while clinical behavior aggressive, showing high rate local recurrence. consists spindle cell, collagen myxoid matrix thus it shows diverse imaging patterns according to its composition. In this case report, surgically diagnosed desmoid presented.

BACKGROUND AND AIM: Solitary fibrous tumor (SFT) is a quite uncommon tumor that commonly occurs in the pleura but occasionally involves an oral cavity. We are reporting this rare case in the oral cavity. The diagnosis depends on microscopic and immunohistochemical features. Patients with these tumors can be carefully treated with local excision, but tumors with...

Giant cell tumor of bone is a locally aggressive tumor with a high local recurrence rate. Several adjuvant therapies have been employed to reduce the recurrence rate, but their effectiveness remains controversial. The authors attempted local administration of zoledronic acid, a nitrogen-containing bisphosphonate that strongly inhibits bone resorption, as an adjuvant treatment for histologically...

AIM To investigate the factors related to the local recurrence-free survival time (LRFS) after surgical treatment of GCT of the sacrum and mobile spine combined with preoperative embolization. MATERIAL AND METHODS We retrospectively reviewed 28 consecutive patients with GCT of the sacrum and mobile spine who underwent initial surgical excision combined with preoperative embolization between 1...

Radiofrequency ablation (RFA) is a new local therapy for hepatocellular carcinoma (HCC). In this study, we investigated the risk factors associated with local recurrence of HCC after single-session RFA with a single electrode insertion. From April 2003 to December 2007, we treated 138 HCC lesions by single-session RFA with a single electrode insertion using the Cool-tip RFA, RTC 2000 and RTC 30...

PURPOSE To evaluate the benefit of adjuvant radiation therapy (RT) for retroperitoneal liposarcoma (RPLS) following gross tumor removal. MATERIALS AND METHODS We reviewed 77 patients with primary RPLS surgically treated between January 2000 and December 2013. Cases with gross residual disease were excluded. Tumor grade was evaluated according to the French Federation of Cancer Centers Sarcoma...
