The Combination of Separation Surgery and Intensity Modulated Radiation Therapy (IMRT) for a Primary Osteosarcoma of the Spine: A Case Report and Literature Review. CLINICAL MEDICINE INSIGHTS-CASE REPORTS 2023; 16:11795476231171891. [PMID: 37151368 PMCID: PMC10159241 DOI: 10.1177/11795476231171891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 04/07/2023] [Indexed: 05/09/2023]
Abstract
Background Primary spinal osteosarcoma is a rare and intractable disease. Although en bloc resection is favorable for longer survival, it is not always achievable. Separation surgery, a partial resection with circumferential separation to safely deliver high-dose irradiation including intensity-modulated radiation therapy (IMRT), has been recently indicated for patients with spinal cord compression secondary to solid tumor metastases. However, little evidence regarding this combination approach to spinal osteosarcoma exists. Case presentation We report a 55-year-old male patient with a T1 tumor who underwent urgent decompression surgery for epidural spinal cord compression. Pathological findings revealed primary osteosarcoma. Separation surgery, IMRT, and adjuvant chemotherapy were applied to reduce the symptoms of epidural spinal cord compression. The patient was alive without local recurrence at the 5-year follow-up. Conclusions Separation surgery with IMRT can be a relatively safe and effective treatment option in patients with osteosarcoma adjacent to spinal cord when en-bloc resection is challenging.

IMRT improves local control in patients with nasopharyngeal carcinoma compared with conventional radiotherapy: propensity score-matched analysis. Jpn J Clin Oncol 2021; 51:1444-1451. [PMID: 34250545 DOI: 10.1093/jjco/hyab100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 06/15/2021] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND It is still controversial whether intensity-modulated radiotherapy has an obvious advantage over conventional radiotherapy. The purposes of this study were to evaluate prognostic factors in pre-treatment characteristics for nasopharyngeal carcinoma and to compare treatment outcomes in patients who received intensity-modulated radiotherapy and patients who received two-dimensional radiotherapy or three-dimensional radiotherapy. METHODS We reviewed patients with nasopharyngeal carcinoma who received chemoradiotherapy in our hospital during the period from 2000 to 2017, and we excluded patients who had a history of surgery for nasopharyngeal carcinoma and those who had distant metastases before treatment. A total of 72 patients who were treated by radiotherapy with concurrent chemotherapy were enrolled. All of the patients were irradiated with a total dose of 58-70 Gy. Overall survival, locoregional control and progression-free survival rates were compared in the groups treated by intensity-modulated radiotherapy and two-dimensional/three-dimensional radiotherapy. Propensity score matching was performed to homogenize the two groups. RESULTS The median follow-up period was 62.5 months. After propensity score matching, in patients treated with intensity-modulated radiotherapy, the 5-year rate of overall survival, locoregional control and progression-free survival were 73.5, 95.2 and 72.7%, respectively. In patients treated with two-dimensional/three-dimensional radiotherapy, the 5-year rate of overall survival, locoregional control and progression-free survival were 69.1, 67.7 and 51.8%, respectively. There was a significant difference between the groups only in locoregional control. Late toxicities of grade 2 or higher were occurred in 38.5 and 24.2% of the patients treated by two-dimensional/three-dimensional radiotherapy and intensity-modulated radiotherapy, respectively. CONCLUSIONS Our results suggested that intensity-modulated radiotherapy is more effective than two-dimensional/three-dimensional radiotherapy in patients with nasopharyngeal carcinoma, especially in locoregional control.

Abstract
BACKGROUND Nasopharyngeal carcinoma (NPC) is a prevalent malignancy in Asia particularly southern China. Comparisons of outcomes of conformal radiotherapy (CRT) and intensity-modulated radiotherapy (IMRT) have been still debated. This meta-analysis was carried out to compare oncologic outcomes of CRT and IMRT in the treatment of NPC. METHODS A literature search was performed through PubMed, Embase, and the Cochrane library databases from their inceptions to November 10, 2018. Two authors assessed the included studies and extracted data independently. Relative studies that compared oncologic outcomes between CRT and IMRT for NPC were included. RESULTS A total of 13 eligible studies were included, which contained 1 RCT, 1 prospective study, and 11 retrospective studies. Our meta-analysis showed that IMRT has increased overall survival (OR = 0.51, 95% CI = 0.41-0.65, P < .00001), locoregional control rate (OR = 0.59, 95% CI = 0.52-0.67, P < .00001), disease-free survival (OR = 0.77, 95% CI = 0.65-0.91, P = .002), and metastasis-free survival (OR = 0.71, 95% CI = 0.54-0.94, P = .01) in comparison with CRT. CONCLUSION The results of this meta-analysis indicate IMRT should be a better option for the treatment of NPC because patients who underwent IMRT may benefit from increased overall survival, locoregional control rate, disease-free survival, and metastasis-free survival compared with CRT.

Abstract
OBJECTIVES Nasopharyngeal carcinoma (NPC) and its treatment can lead to cervical spine pathologies such as metastases, osteoradionecrosis (ORN) and infection. However, the occurrence rate and relationship between timing of diagnosis and outcomes of the ever-advancing technology of radiation therapy is largely unknown. Hence, the aim of this study is to determine the prevalence and impact of cervical spine pathologies in patients with NPC. MATERIALS AND METHODS This was a cross-sectional study of all newly diagnosed cases of NPC from 2007 to 2016 at a tertiary referral oncology and spine centre with minimum 1-year post-treatment follow-up. All cervical spine pathologies, their treatment and outcomes were determined. Presentation, onset time and correlations of the cervical spine pathologies with mortality and risk factors were also analysed. RESULTS Out of 605 cases of verified cases of NPC, cervical spine pathologies were seen in 8.9% of patients. New onset neck pain was seen in 5.3%, symptomatic cervical spondylosis in 4.8%, cervical spine metastases in 2.5%, local tumour invasion in 0.8%, cervical ORN in 0.7%, osteomyelitis in 0.7%, radiculopathy in 0.3%, and myelopathy in 0.3%. Cervical spine pathologies were associated with an increased risk (odds ratio: 2.73) in overall mortality. Cervical spine metastases, invasion, ORN and infection were associated with significantly higher risk of mortality (p = 0.01-0.02). CONCLUSION Cervical spine pathologies in patients with NPC are heterogenous but not uncommon. Neck pain is prevalent but is often benign. ORN and osteomyelitis of the cervical spine is uncommon but have large clinical implications including higher mortality with subtle presentations.

Abstract
Background MicroRNA-21 (miR-21) was previously reported being dysregulated in many kinds of cancer including esophageal squamous cell carcinoma (ESCC). In the present study, we aimed to investigate the role of miR-21 in ESCC, especially in its effects on radiation-sensitivity of ESCC. Methods Expression of miR-21 was detected in 63 pairs ESCC tumor and adjacent non-tumoral tissues using qRT-PCR, correlation between miR-21 and clinicopathological feature of ESCC was analyzed. The role of miR-21 in the proliferation, cell cycle and apoptosis of ESCC cells during irradiation were studied. Results MicroRNA-21 expression was significantly increased in ESCC tumor tissues. Expression of miR-21 was positively associated with advanced clinical stage. Under irradiation, overexpression of miR-21 increased cell proliferation and cells in S phase, and inhibited cell apoptosis of ESCC cells. In contrast, knockdown of miR-21 had an opposite effect. Conclusions Downregulation of miR-21 inhibited the radiation-resistance of ESCC, whereas overexpression of miR-21 increased the radiation-resistance. MiR-21 is a potential novel target for developing specific treatment interventions in ESCC in future.

Diffusion-kurtosis imaging predicts early radiotherapy response in nasopharyngeal carcinoma patients. Oncotarget 2017; 8:66128-66136. [PMID: 29029498 PMCID: PMC5630398 DOI: 10.18632/oncotarget.19820] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Accepted: 06/28/2017] [Indexed: 12/17/2022] Open
Abstract
In this prospective study, we analyzed diffusion kurtosis imaging (DKI) parameters to predict the early response to radiotherapy in 23 nasopharyngeal carcinoma (NPC) patients. All patients underwent conventional magnetic resonance imaging (MRI) and DKI before and after radiotherapy. The patients were divided into response (RG; no residual tumors; 16/23 patients) and no-response (NRG; residual tumors; 7/23 patients) groups, based on MRI and biopsy results 3 months after radiotherapy. The maximum diameter of tumors in RG and NRG patients were similar prior to radiotherapy (p=0.103). The pretreatment diffusion coefficient (D) parameters (Daxis, Dmean and Drad) were higher in RG than NRG patients (p=0.022, p=0.027 and p=0.027). Conversely, the pre-treatment fractional anisotropy (FA) and kurtosis coefficient (K) parameters (Kaxis, Kfa, Kmean, Krad and Mkt) were lower in RG than NRG patients (p=0.015, p=0.022, p=0.008, p=0.004, p=0.001, p=0.002). The Krad coefficient (0.76) was the best parameter to predict the radiotherapy response. Based on receiver operating characteristic curve analysis Krad showed 71.4% sensitivity and 93.7% specificity (AUC: 0.897, 95% CI, 0.756-1). Multivariate analysis indicated DKI parameters were independent prognostic factors for the short-term effect in NPC. Thus, DKI predicts the early response to radiotherapy in NPC patients.

Cyclooxygenase-2 expression is positively associated with lymph node metastasis in nasopharyngeal carcinoma. PLoS One 2017; 12:e0173641. [PMID: 28301518 PMCID: PMC5354404 DOI: 10.1371/journal.pone.0173641] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2016] [Accepted: 02/23/2017] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Accumulating evidence has demonstrated that cyclooxygenase-2 (COX-2) is involved in head and neck cancers, especially in nasopharyngeal carcinoma (NPC). However, the association between COX-2 expression and lymph node metastasis in NPC remains uncertain. This systematic review and meta-analysis meta-analysis investigated the relationship between COX-2 expression and lymph node metastasis and other signs of disease progression in NPC. METHODS Previously published studies assessing COX-2 expression and lymph node metastasis in NPC were identified in four English databases and three Chinese ones (Pubmed, Embase, Cochrane Database of Systematic Reviews, Web of Science, China National Knowledge Infrastructure, Wanfang, Vip Journal Integration Platform) up to November 2016. Quality of all eligible studies was assessed using the Newcastle-Ottawa Quality Assessment Scale (NOS). Pooled odds ratios (OR) and their 95% confidence intervals (95%CI) were calculated with fixed-effects or random-effects model to evaluate the effects of COX-2 expression on lymph node metastasis. RESULTS A total of 27 studies with 1797 NPC patients met the inclusion criteria. The expression of COX-2 was significantly higher in patients with nasopharyngeal carcinoma than those without the carcinoma, with a combined OR of 21.17 (95%CI = 15.02-29.85, I2 = 35.1%, Pheterogeneity = 0.070). A statistically significant association between COX-2 expression and lymph node metastasis in NPC patients, with an OR of 4.44 (95%CI = 3.46-5.70, I2 = 38.3%, Pheterogeneity = 0.024), and with other indicators of disease progression. Subgroup analyses based on COX-2 assay and staging criteria of TNM showed no significant heterogeneity. CONCLUSIONS The results suggest that expression of COX-2 is associated with lymph node metastasis and disease progression in NPC, indicating a potential role in evaluation of prognosis and in treatment decisions. COX-2 inhibitors have potential in the treatment of NPC that should be further investigated.
