Oligometastases and oligo-recurrence are among the most important notions of metastatic and recurrent cancer. The concept of oligometastases is related to the notion that cancer patients with 1-5 metastatic or recurrent lesions that could be treated by local therapy achieve long-term survival or cure, while the concept of oligo-recurrence is related to the notion that cancer patients with 1-5 m...

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 ...

OBJECTIVE We wanted to evaluate whether tumors located in a segmental border zone are predisposed to local recurrence after performing segmental transarterial chemoembolization for hepatocellular carcinoma. MATERIALS AND METHODS Seventy-three hepatocellular carcinoma nodules were retrospectively analyzed for local tumor recurrence after performing segmental transarterial chemoembolization by ...

BACKGROUND The proximity of head and neck (H&N) melanomas to critical anatomical structures requires that surgeons achieve a balance between adequate margins of excision and the functional and cosmetic needs of patients. This study sought to determine the risk associated with reducing margins of wide local excision (WLE) in H&N melanoma and to identify risk factors of recurrence. METHODS Seve...

Background. Here we present a concise review on the evaluation and management of locally recurrent rectal cancer, which despite marked reductions in the rate of recurrent rectal cancer remains an important problem. Methods. This educational review discusses the diagnosis, evaluation, and management of recurrent rectal cancer. Results. Despite improvements in both the neoadjuvant and surgical ma...

AIMS To evaluate the influence of involvement of the peritoneal surface by carcinoma of the rectum on local recurrence and prognosis. METHODS Prospective analysis of pathological prognostic factors in 209 resections for rectal carcinoma between 1988 and 1993 with meticulous pathological technique particularly to assess the relation of tumour to the peritoneal surface. Comprehensive clinical f...

STUDY DESIGN A retrospective analysis of 169 adult patients operated for a conventional spinal schwannoma from the AOSpine Multicenter Primary Spinal Tumors Database. OBJECTIVE The aim of this study is to identify risk factors for local recurrence of conventional spinal schwannoma in patients who had surgery. SUMMARY OF BACKGROUND DATA Schwannomas account for up to 30% of all adult spinal t...

Wide local excision (WLE) with a safety margin is the standard of treatment for primary head and neck cutaneous malignant melanoma (HNCMM). Studies have demonstrated inconsistency in recurrence rates following immediate versus delayed reconstruction. The objectives of this study were to assess and compare recurrence rates after WLE of HNCMM followed by immediate or delayed reconstruction in det...

Background: The purpose of this study is to clarify the utility of thallium-201 single photon emission tomography (Tl-SPECT) for predicting local recurrence after stereotactic radiotherapy (SRT) by comparing it with 18fl udeoxyglucose-positron emission tomography (FDG-PET). Since Tl-SPECT can be performed at general hospitals, the ability of Tl-SPECT to predict local recurrence after SRT is cli...
