Assessing the Performance of Prognostic Scores in Patients with Spinal Metastases from Lung Cancer Undergoing Non-surgical Treatment.

Study Design: Retrospective study.

Purpose: The purpose of this study was to see how well the Tomita score, revised Tokuhashi score, modified Bauer score, Van der Linden score, classic Skeletal Oncology Research Group (SORG) algorithm, SORG nomogram, and New England Spinal Metastasis Score (NESMS) predicted 3-month, 6-month, and 1-year survival of non-surgical lung cancer spinal metastases.

Overview Of Literature: There has been no study assessing the performance of prognostic scores for non-surgical lung cancer spinal metastases.

Management of Oligometastatic Breast Cancer: An Expert Committee's Opinion.

Patients with oligometastatic breast cancer (BC) are candidates of choice for metastasis-directed therapy (MDT). This paper summarizes the opinions of an expert committee about the management of oligometastatic BC. The experts could complete the questionnaire from 13 September 2021, to 10 October 2021, followed by a discussion.

Spinal Metastasis in Multiple Primary Malignancies Involving Lung Cancer: Clinical Characteristics and Survival.

Objective: The incidence of multiple primary malignancies (MPM) has increased in recent decades. Our aim was to evaluate incidence, clinical features, and survival in cases of spinal metastases from MPM in which one of the malignancies is lung cancer.

Methods: We retrospectively reviewed an institutional database of lung cancer patients with spinal metastasis and extracted all cases of MPM.

A Phase II Multi-institutional Clinical Trial Assessing Fractionated Simultaneous In-Field Boost Radiotherapy for Brain Oligometastases.

Purpose/Objective Published preclinical and phase I clinical trial data suggest that fractionated lesional radiotherapy with 60 Gy in 10 fractions can serve as an alternative approach to single fraction radiosurgical boost for brain oligometastases.  Methods and Materials A phase II clinical trial (NCT01543542) of a total of 60 Gy in 10 fractions of lesional (one to three) radiotherapy (given simultaneously with whole-brain helical tomotherapy with 30 Gy in 10 fractions) was conducted at five institutions. We hypothesized that fractionated radiotherapy would be considered unsuitable if the median overall survival (OS) was degraded by two months or if six-month intracranial control (ICC) and intracranial lesion (ILC) were inferior by 10% compared with the published RTOG 9508 results.

Hypofractionated Radiation Therapy for Large Brain Metastases.

Single fraction radiosurgery (SRS) treatment is an effective and recognized alternative to whole brain radiation for brain metastasis. However, SRS is not always possible, especially in tumors of a larger diameter where the administration of high dose in a single fraction is limited by the possibility of acute and late side effects and the dose to the surrounding organs at risk. Hypofractionated radiation therapy allows the delivery of high doses of radiation per fraction while minimizing adverse events, all the while maintaining good local control of lesions.

Spine stereotactic body radiotherapy for renal cell cancer spinal metastases: analysis of outcomes and risk of vertebral compression fracture.

Object: The aim of this study was to evaluate local control (LC) and the risk of vertebral compression fracture (VCF) after stereotactic body radiotherapy (SBRT) in patients with renal cell cancer spinal metastases.

Methods: Prospectively collected data on 71 spinal segments treated with SBRT in 37 patients were reviewed. The median follow-up was 12.

Vertebral compression fracture (VCF) after spine stereotactic body radiation therapy (SBRT): analysis of predictive factors.

Purpose: Vertebral compression fractures (VCFs) are increasingly observed after spine stereotactic body radiation therapy (SBRT). The aim of this study was to determine the risk of VCF after spine SBRT and identify clinical and dosimetric factors predictive for VCF. The analysis incorporated the recently described Spinal Instability Neoplastic Score (SINS) criteria.

Long-term outcomes for adult craniopharyngioma following radiation therapy.

Background: We report long-term outcomes in adult patients with craniopharyngioma following surgery and radiation therapy (RT).

Material And Methods: Fifty-three patients treated with RT (median, 50 Gy in 25 fractions) between 1980 and 2009 with pathologically confirmed craniopharyngioma were reviewed (53% solid and 47% cystic/solid). The median age was 53 years (range, 22-76), 53% were female, 83% were sub-totally resected, 6% were gross totally resected and 11% had a biopsy and/or cyst aspiration alone.

Case report: grade 4 radiation-induced colitis following conventional reirradiation to a hip metastasis.

Palliative radiation therapy has been widely used for treatment of pain from metastatic bone disease. However, reirradiation is required in approximately 20% of patients initially treated with single fraction conventional palliative radiotherapy. There is a paucity of literature as to toxicities associated with reirradiation, and a lack of knowledge overall as to the cumulative dose limits for the organs at risk.

Stereotactic body radiotherapy is an effective treatment in reirradiating spinal metastases: current status and practical considerations for safe practice.

Spinal metastases are a relatively common manifestation in advanced cancer patients. Low-dose conventional radiotherapy has long been the mainstay of treatment under the assumption that patients have a limited life expectancy in the order of 3-6 months. However, with new developments in systemic therapies, patients are surviving longer than expected.
