Introduction
Elderly patients are more prone to encounter some adverse factors when they receive chemotherapy compared to younger patients. Addition of rituximab to a reduced dose (RD) of cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) chemotherapy might improve patient outcomes with an improved toxicity profile when provided to elderly patients with diffuse large B-cell lymphoma.Patients and Methods
A total of 53 patients aged ≥ 65 years with diffuse large B-cell lymphoma diagnosed between August 2012 and December 2014 were enrolled onto this study. RD-R-CHOP regimen consisted of rituximab at 375 mg/m2, cyclophosphamide at 600 mg/m2, doxorubicin at 30 mg/m2, and vincristine at 1 mg on day 1 of each cycle and 40 mg of prednisone on days 1 to 5. Patients received granulocyte colony-stimulating factor if they experienced grade 3/4 neutropenia or febrile neutropenia during any cycle.Results
The median follow-up duration was 18 months (range, 1-44 months). Complete response and overall response rates were 64.1% and 81.1%, respectively. Three-year event-free and overall survival rates were 45.7% ± 8.4% and 62.7% ± 8.1%, respectively. Grade 3/4 neutropenia occurred in 20 patients (37.7%), while febrile neutropenia occurred in 7 patients (20.7%).Conclusion
Outcomes of RD-R-CHOP chemotherapy were comparable to those of standard-dose R-CHOP or previous dose-adjusted R-CHOP chemotherapy. In the future, strategies such as tailored therapy based on geriatric assessment results are needed to determine the chemotherapeutic dosage. 相似文献2.

Introduction
Major pathologic response after neoadjuvant chemotherapy (NAC) for NSCLC has been defined as 10% or less residual viable tumor without distinguishing between histologic types. We sought to investigate whether the optimal cutoff percentage of residual viable tumor for predicting survival differs between lung adenocarcinoma (ADC) and squamous cell carcinoma (SCC).Methods
Tumor slides from 272 patients treated with NAC and surgery for clinical stage II-III NSCLC (ADC, n = 192; SCC, n = 80) were reviewed. The optimal cutoff percentage of viable tumor for predicting lung cancer–specific cumulative incidence of death (LC-CID) was determined using maximally selected rank statistics. LC-CID was analyzed using a competing-risks approach. Overall survival was evaluated using Kaplan-Meier methods and Cox proportional hazard analysis.Results
Patients with SCC had a better response to NAC (median percentage of viable tumor: SCC versus ADC, 40% versus 60%; p = 0.027). Major pathologic response (≤10% viable tumor) was observed in 26% of SCC cases versus 12% of ADC cases (p = 0.004). The optimal cutoff percentage of viable tumor for LC-CID was 10% for SCC and 65% for ADC. On multivariable analysis, viable tumor 10% or less was an independent factor for better LC-CID (p = 0.035) in patients with SCC; in patients with ADC, viable tumor 65% or less was a factor for better LC-CID (p = 0.033) and overall survival (p = 0.050).Conclusions
In response to NAC, the optimal cutoff percentage of viable tumor for predicting survival differs between ADC and SCC. Our findings have implications for the pathologic assessment of resected specimens, especially in upcoming clinical trials design. 相似文献3.

Introduction
Stereotactic body radiation therapy (SBRT) is a promising curative treatment for early-stage NSCLC. It is unclear if survival outcomes for SBRT are influenced by a lack of pathological confirmation of malignancy and staging of disease in these patients. In this systematic review and meta-analysis, we assess survival outcomes after SBRT in studies with patients with clinically diagnosed versus biopsy-proven early-stage NSCLC.Methods
The main databases were searched for trials and cohort studies without restrictions to publication status or language. Two independent researchers performed the screening and selection of eligible studies. Outcomes were overall survival, cancer-specific survival, and disease-free survival. The inverse variance method and the random effects method for meta-analysis were used to assess pooled survival estimates.Results
A total of 11,195 nonduplicate records were identified by the original search strategy. After screening by title and abstract, 1051 potentially eligible records were identified. A total of 43 articles were included. The comparative studies showed lower 3-year overall survival and lower 2-year and 5-year cancer-specific survival for biopsy-proven disease compared to clinical disease. However, 5-year overall survival was the same for both groups. For the pooled estimates, 3-year disease-free survival and 2-year cancer-specific survival were lower for biopsied disease.Conclusions
Results of this systematic review and meta-analysis show a discrepancy in oncological outcomes for patients undergoing SBRT for suspected early-stage NSCLC in whom there is pathologic conformation of malignancy and those who there is only a clinical diagnose of NSCLC. These results emphasize the importance of obtaining pathologic proof of malignancy. 相似文献4.
Purpose
To assess the pharmacologic costs of second-line treatments for metastatic renal-cell cancer (mRCC).Methods
The present evaluation was restricted to pivotal phase 3 randomized controlled trials in second-line for mRCC. We calculated the pharmacologic costs necessary to get the benefit in progression-free survival and overall survival (OS) for each trial. The costs of drugs are at the pharmacy of our hospital and are expressed in euros.Results
Our analysis evaluated 5 phase 3 randomized controlled trials including 3112 patients. The lowest cost per month of progression-free survival and OS gained was associated with the use of cabozantinib (€2006 and €1473, respectively), while everolimus had the highest cost per month of OS gained (€28,590).Conclusion
Combining pharmacologic costs of drugs with the measure of efficacy represented by OS, cabozantinib is a cost-effective second-line treatments for patients with mRCC. 相似文献5.

Background
Single-agent gemcitabine is a moderately effective compound in metastatic breast cancer (mBC) treatment. Carboplatin is frequently used in addition to gemcitabine to improve tumor responses, but with an unclear effect on survival outcomes. In this study we evaluated the antitumor efficacy and safety profiles of gemcitabine and carboplatin-gemcitabine in mBC patients.Patients and Methods
We retrospectively collected data on patients treated between April 2012 and February 2018 with gemcitabine 800 mg/m2or carboplatin at an area under the curve of 2 with gemcitabine 800 mg/m2, given on days 1 and 8 every 21 days. We compared progression-free survival (PFS), objective response rate (ORR), overall survival, and incidence of adverse events (AEs) in the 2 cohorts.Results
Of 163 consecutive patients who met the inclusion criteria, 75 received gemcitabine and 88 carboplatin-gemcitabine. Patients in the combination cohort had received a lower number of previous chemotherapy lines (2 vs. 3), and were less likely to have received carboplatin (9 patients [10%] vs. 34 patients [45%]; P < .0001). We found no PFS differences in carboplatin-gemcitabine and gemcitabine cohorts (4.24 vs. 4.61 months; adjusted hazard ratio, 0.98; P = .92), whereas the combination was associated with a trend toward higher ORR (18 patients [20.4%] vs. 8 patients [10.6%]; P = .089) and with significantly higher incidence of Grade 3/4 neutropenia (30 patients [34%] vs. 5 patients [6.6%]; P < .0001).Conclusion
Using carboplatin in addition to gemcitabine is associated with more hematologic AEs but not with better PFS. Although single-agent gemcitabine remains a treatment option for heavily pretreated mBC patients, finding biomarkers of response to platinum salts might help to identify patients more likely to benefit from carboplatin-gemcitabine. 相似文献6.

Introduction
Nivolumab is effective in the treatment of previously treated patients with advanced NSCLC. However, its radiological evaluation is challenging because of atypical patterns of response such as pseudoprogression. We examined the characteristics and outcomes of previously treated patients with NSCLC who were treated with nivolumab and experienced development of pseudoprogression.Methods
We conducted a 15-center retrospective cohort study of previously treated patients with advanced NSCLC who received nivolumab monotherapy. For the patients who showed pseudoprogression, we defined progression-free survival 1 (PFS1) as the time to Response Evaluation Criteria in Solid Tumors–defined first progressive disease and progression-free survival 2 (PFS2) as the time to Response Evaluation Criteria in Solid Tumors–defined second progressive disease or death.Results
Among the 542 patients included, 20% and 53% showed a typical response and progression, respectively. Of the 14 (3%) patients who showed pseudoprogression, most (n = 10) showed a response within 3 months of nivolumab treatment. The median PFS1 and PFS2 were 1.0 and 7.3 months, respectively. The median PFS2 was significantly shorter in the patients who showed pseudoprogression than the PFS of the patients with a typical response (p < 0.001). In contrast, patients showing pseudoprogression had significantly longer overall survival than did patients showing typical progression (p = 0.001).Conclusions
Pseudoprogression was uncommon, and the duration of response in patients who showed pseudoprogression was shorter than that in patients who showed a typical response. However, the survival benefit of pseudoprogression was markedly better than that of typical progression. Further research is required to elucidate the characteristics of and mechanisms underlying pseudoprogression. 相似文献7.

Background
The aim of this study was to determine if, in inflammatory breast cancer (IBC), baseline metabolic activity (maximum standardized uptake value [SUVmax]) of primary tumor and involved regional lymph nodes (IRLN) are prognostic markers of response after neoadjuvant systemic therapy (NAS).Patients and Methods
Baseline 2-deoxy-2-[18F]fluoro-D-glucose (FDG) positron emission tomography/computed tomography scans were retrospectively reviewed among 61 women with IBC who received NAS, had mastectomy, and had available pathology reports. Primary tumor and IRLN SUVmax were compared between patients with a pathologic complete response (pCR) versus those with residual disease after NAS. A multivariate Cox model was fit to evaluate the effects of SUVmax on overall survival, adjusting for pCR and stratified by receptor status and disease stage.Results
SUVmax in primary IBC tumors tended to increase with tumor grade (trend test P = .06) and was lower for stage III, non–triple-negative (TN) versus stage III, TN and stage IV, non-TN disease (P = .04). Neither primary tumor nor IRLN SUVmax was significantly different comparing pCR versus residual disease after NAS. Adjusting for pathology response in the overall survival model stratified by stage and receptor status, baseline SUVmax in primary IBC tumor was associated with an estimated hazard ratio of 1.10 (95% confidence interval, 0.97-1.25; P = .15) for patients with stage III, TN and stage IV, non-TN disease. This hazard ratio corresponded to a 1.74-fold risk of death with 1 standard deviation (SD = 5.9) increase in baseline SUVmax in primary IBC tumor.Conclusion
2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography provides prognostic information for newly diagnosed IBC. Larger studies are needed to confirm these findings and assess how such early information could affect treatment choices for IBC in the neoadjuvant setting. 相似文献8.

Background
Eribulin has efficacy in patients with progression after ≥ 1 chemotherapeutic regimen for metastatic breast cancer (MBC). A short disease-free interval (DFI) and previous use of taxanes in the neoadjuvant or adjuvant setting have been associated with worse outcomes for patients receiving first-line chemotherapy for HER2-negative MBC. The aim of the present trial was to evaluate the efficacy and safety of eribulin as first-line therapy for patients with HER2-negative MBC with these poor prognostic factors.Patients and Methods
Eribulin monotherapy was administered until disease progression or unacceptable toxicity. The principal selection criteria were HER2 negativity without previous chemotherapy for MBC, the previous use of taxanes for early-stage breast cancer, and a DFI of < 36 months (subsequently amended to 48 months). The primary endpoint was the investigator-assessed time to progression. The secondary endpoints included overall survival, progression-free survival, objective response rate, clinical benefit rate, duration of response, and toxicity profile. A total of 53 patients were enrolled and received ≥ 1 dose of eribulin.Results
The median patient age was 47 years (range, 23-82.8 years). The median DFI was 15.7 months (range, 0.1-46.4 months). The median investigator-assessed time to progression was 4.1 months (range, 0.2-27.8 months; 95% confidence interval, 3.2-6.2 months). The objective response and clinical benefit rate was 20.8% and 26.4%, respectively. All-grade and grade 3/4 adverse events developed in 96.2% and 69.8% of patients, respectively. The most common treatment-related adverse events were neutropenia, leukopenia, alopecia, nausea, and anemia.Conclusion
Eribulin is effective and safe as first-line therapy for aggressive taxane-pretreated HER2-negative MBC. 相似文献9.

Aim
There are few data to inform on the use of response assessment 2-[fluorine-18]-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography-computed tomography (PET-CT) following radical radiotherapy without chemotherapy for head and neck squamous cell carcinoma (HNSCC). This retrospective study evaluated the accuracy of PET-CT in HNSCC following radical radiotherapy.Materials and methods
In total, 138 patients with HNSCC treated with radical radiotherapy without chemotherapy who underwent a baseline and response assessment FDG PET-CT were identified. FDG PET-CT outcomes were analysed with reference to clinicopathological outcomes.Results
The median follow-up was 26 months. FDG-avid disease at baseline was present for the primary site and lymph nodes in 118 and 86 patients, respectively. With regard to the primary tumour, the negative predictive value (NPV) of a complete metabolic response (CMR) was 95%; the positive predictive value (PPV) of equivocal uptake and a positive scan were 6% and 82%, respectively. The likelihood ratios for a CMR, equivocal and positive scans of the primary site were 0.19, 0.22, 14.8, respectively. With regard to lymph node disease, the NPV of a CMR was 91%, the PPV of equivocal uptake and a positive scan were 33% and 88%, respectively. Likelihood ratios for lymph node disease for CMR, equivocal and positive scans were 0.19, 0.97 and 15.1, respectively.Conclusion
Compared with the accuracy reported in the literature following chemoradiotherapy, response assessment FDG PET-CT following radical radiotherapy without chemotherapy had a similarly high NPV, whereas the PPV following a positive scan was higher. 相似文献10.

Background
Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.Patients and Methods
We retrospectively evaluated the incidence of CVEs on 233 consecutive patients with chronic myeloid leukemia, of which 116 were treated with imatinib, 75 with dasatinib, and 42 with nilotinib. The median follow-up was 2047, 1712, and 1773 days, respectively.Results
The cumulative incidence of CVEs was 4.29%. Three events occurred during dasatinib treatment, 6 during nilotinib treatment, and none during imatinib treatment (P ≤ .001). Arterial occlusive events occurred in 2 (2.6%) of 75 patients treated with dasatinib and in 6 (14.2%) of 42 patients treated with nilotinib (P ≤ .001). Furthermore, all of them occurred in patients with high-risk (n = 2) and very high-risk (n = 6) cardiovascular risk, contributing to 4.3% of mortality.Conclusion
CVEs were more frequent in patients treated with second-generation tyrosine kinase inhibitors. Arterial occlusive events were more frequent in patients treated with nilotinib, with high and very high cardiovascular risk. 相似文献11.

Aims
To obtain an overview of the management and outcomes of children aged 18 years or younger diagnosed with differentiated thyroid carcinoma of follicular cell origin across the UK, by collecting and analysing data from the limited number of centres treating these patients. This multicentre data might provide a more realistic perspective than single-institution series.Materials and methods
Six centres submitted data extracted from historical records on patients aged 18 years or younger, diagnosed between 1964 and 2017. The univariate and multivariable Cox proportional hazard model was used to identify potential predictors of progression-free survival, using national data as a control.Results
Data on 166 patients were available for analysis. Females (74%) were predominant, and the age ranged from 3 to 19 years at diagnosis, mean 14.1 years. Nodal metastases were present in 51%; 12% had distant metastases. After surgery, 95% received radioactive iodine (39% on more than one occasion) and 4% received external beam radiotherapy. With a median follow-up duration of 5 years, 69% are alive with no evidence of disease; 20% are alive with a raised thyroglobulin level as the only evidence of residual disease; 6% have residual structural disease detectable on imaging; 2% have died, from cerebral metastases.Conclusion
Despite most patients having advanced disease at presentation, outcomes are very good. A national prospective registry should allow systematic collection of good-quality data and may facilitate research to further improve outcomes. 相似文献12.

Introduction
Breast cancer (BC) is the most common cancer in women, and the incidence of brain metastasis (BM) from BC ranges from 20% to 30%, with a median survival of 10 to 15 months. Previous reports have shown that the presence of obesity or diabetes negatively impacts survival. The present study investigates the association between obesity or diabetes mellitus (DM) and overall survival of patients with BC with BM.Materials and Methods
A database from 2 referral centers for the period of July 2014 to February 2018 was analyzed. The inclusion criteria were as follows: patients who had a confirmed diagnosis of BC with BM were followed and treated at these centers. Demographic data, body weight and height, clinical and oncologic history, functional status, prognostic scales, and prognoses were examined.Results
A total of 228 patients were included. The median age at BM was 50 years; the median survival after diagnosis was 12.1 months; 108 patients had a body mass index (BMI) ≥ 25, and 40 (17%) patients had DM. The association between survival and the presence of BMI > 25 exhibited a P value of 0.3.Discussion
We found no association between overweight, obesity, or DM and survival in patients with BC with BM. The role of obesity in cancer is a robust research topic, as there are many questions to be answered.Conclusion
Obesity as a prognostic indicator should be further studied, because we found no association between overall survival and either patients with BM from BC with a BMI > 25 or those with normal weight. 相似文献13.

Background
Locally advanced NSCLC is one of the most heterogeneous conditions, with multidimensional treatments involved. Neoadjuvant therapy had been commonly considered an optimal management strategy for patients with operable locally advanced. However, as targeted therapy has been widely applied in advanced NSCLC, neoadjuvant targeted therapy has remained poorly explored in locally advanced disease.Methods
We have described 11 ALK receptor tyrosine kinase gene (ALK)-positive patients with pathologically confirmed N2 NSCLC who were treated with neoadjuvant crizotinib. All the patients were treatment naive and received crizotinib at a starting dose of 250 mg twice daily. Patient 3 was provided with dynamic monitoring before and after neoadjuvant therapy through next-generation sequencing of plasma and tissue. In case 4, next-generation sequencing of preoperative tissue was performed.Results
Of the 11 patients, 10 had a partial response and one was stable disease after neoadjuvant crizotinib, with one suffering from grade 4 hepatic damage. Of the 11 patients, 10 (91.0%) received an R0 resection and 2 patients achieved a pathological complete response to neoadjuvant crizotinib. Six patients had disease recurrence, with five of them receiving crizotinib as first-line treatment and achieving a long duration of response. Dynamic monitoring of both plasma and tissue simultaneously indicated a decrease in sensitive ALK signaling in patient 3 and a partial response (approximately 50% of partial response), and no ALK-dependent resistance variants were captured.Conclusion
Neoadjuvant crizotinib may be feasible and well tolerated in locally advanced disease for complete resection. Crizotinib therapy before surgery may provide thorough elimination of circulating molecular residual disease and not influence the reuse of first-line crizotinib, but ongoing prospective trials are warranted to prove its efficacy in the neoadjuvant setting. 相似文献14.

Background
Colon cancer is the third most frequent cancer diagnosis, and primary payer status has been shown to be associated with treatment modalities and survival in cancer patients. The goal of our study was to determine the between-insurance differences in survival in patients with clinical stage III colon cancer using data from the National Cancer Database (NCDB).Materials and Methods
We identified 130,998 patients with clinical stage III colon cancer in the NCDB diagnosed from 2004 to 2012. Kaplan-Meier curves and multivariable Cox regression models were used to determine the association between insurance status and survival.Results
Patients with private insurance plans were 28%, 30%, and 16% less likely to die than were uninsured patients, Medicaid recipients, and Medicare beneficiaries, respectively. Medicare patients were 14% were less likely to die compared with uninsured patients. Patients receiving chemotherapy were, on average, 65% less likely to die compared with the patients not receiving chemotherapy.Conclusion
Private insurance and a greater socioeconomic status were associated with increased patient survival compared with other insurance plans or the lack of insurance. Future research should continue to unravel how socioeconomic status and insurance status contribute to the quality of care and survival of oncologic patients. 相似文献15.

Background
Based on estrogen active substances, many women consume soy foods in the belief that it could prevent breast cancer (BC). Women with different molecular subtypes would be likely to have diverse reactions to soy foods, especially those with the estrogen-receptor-positive (ER+) subtype. The aim of the current study is to identify the differentially expressed genes (DEGs) on soy foods in premenopausal patients with Lumina A subtype of BC (LABC) after soy food treatment, and to further investigate the critical molecule change.Materials and Methods
GSE58792 retrieved from Gene Expression Omnibus was analyzed to obtain DEGs using GEO2R. Gene Ontology and pathway enrichment analysis were performed using FunRich and GeneMINIA. Overall survival of critical genes was performed by the Kaplan-Meier plotter online tool.Results
A total of 108 DEGs were obtained from the dataset, among which 35 were up-regulated and 73 down-regulated. Soy foods significantly reduced the expression of TFF3, TFF1, GATA3, and ESR1, which were related to the activity of the ER-related pathway and the sensitivity of tamoxifen. Furthermore, the lower expressions of TOX3, FSIP1, ESR1, and CLGN were related to prolonged survival time of patients with BC. The most significant signaling pathways were epithelial-to-mesenchymal transition in up-regulated DEGs, mesenchymal-to-epithelial transition, and mammary gland alveolus development in down-regulated DEGs, which were all related to the development and prognosis of BC.Conclusions
Soy foods could dramatically alter the ER-related gene profile in LABC. Particularly, down-regulated DEGs of TFF3, TFF1, GATA3, and ESR1 might weaken the sensitivity of tamoxifen and increase the efficacy of neoadjuvant chemotherapy in premenopausal patients with LABC. 相似文献17.

Background
There are no previous reports directly evaluating immunologic conditions in tumor microenvironment including both bladder cancer (BCa) and upper urinary tract carcinoma (UTUC). In this study, we aimed to clarify the difference of immunity status and its clinical significance depending on the tumor site in urothelial carcinoma.Patients and Methods
Tumor tissue–infiltrating lymphocytes were extracted from 70 urothelial cancer patients who underwent surgical resection (52 cases of BCa and 18 cases of UTUC). The immunologic classification was established by unsupervised clustering analysis according to the expression ratio of 9 extracellular surface markers measured by flow cytometry, and we examined the relationship between immunologic classification and clinical importance such as pathologic status and prognosis (progression-free survival and cancer-specific survival).Results
The immunologic condition was classified into 2 groups. Group 1 (n = 41) comprised the CD4 T-cell–dominant group and group 2 (n = 29) the immunologically activated group. This immunologic classification was significantly correlated with tumor grade (P = .020) but not tumor location in multivariate analysis. In invasive BCa patients (n = 33), progression-free survival and cancer-specific survival of group 2 were significantly worse than those of group 1 (P = .021 and P = .022, respectively), while there was no significant difference between groups 1 and 2 in patients with invasive UTUC (n = 17).Conclusion
Although there was no difference in the local immunologic condition of urothelial carcinoma between BCa and UTUC, its significance as a prognostic predictor might vary depending on tumor site. 相似文献18.
Purpose
This study aimed to determine the pain response rates after conventional radiation therapy (RT) for painful bone metastases in prospective nonrandomized studies, which better reflect daily practice than randomized controlled trials.Methods and materials
A literature search was conducted in PubMed and Scopus for articles published between 2002 and 2018. We only included articles in which pain response after RT was assessed using the International Consensus Endpoint initially published in 2002, or the updated version from 2012. In addition, to be included in this review, the study design was required to be prospective or based on prospectively collected data. Our primary outcomes of interest were the overall and complete response rates after conventional RT for bone metastases.Results
Of the 2863 articles identified in our database search, 12 met the inclusion criteria. Six studies excluded patients with features of complicated bone metastases. Only 2 papers reported exclusion criteria regarding analgesic use. Radiation schedules that were frequently used were 1 × 8 Gy, 5 × 4 Gy, and 10 × 3 Gy. The overall response rate in evaluable patients was 55%, and 754 of the 1379 evaluable patients experienced a complete or partial response. The complete response rate was 15% (196 of 1348 evaluable patients). In the intent-to-treat patient group, the overall response rate was 29% (754 of 2559 enrolled patients), and the complete response rate 8% (196 of 2528 enrolled patients).Conclusions
We determined the pain response rates after conventional RT for painful bone metastases in prospective nonrandomized studies. The present review may provide benchmarks for future nonrandomized studies that investigate palliative RT for bone metastases. 相似文献19.

Aims
Total radiation dose does not predict pain response in conventionally fractionated radiotherapy for bone metastases. By contrast, in radiotherapy for solid painful tumours other than bone metastases, it is unknown whether there is a dose–response relationship. We sought to determine whether a higher total radiation dose predicted a higher pain response rate in palliative radiotherapy for non-bone painful lesions.Materials and methods
We carried out a secondary analysis of a prospective observational study. For patients scheduled for radiotherapy for painful tumours, Brief Pain Inventory data were collected at baseline and at 1, 2 and 3 months after the start of radiotherapy. The predictive value of total radiation dose was evaluated using the Fine–Gray model, in which death without a pain response was treated as a competing risk.Results
Of the 203 patients with solid painful tumours, 78 (38%) had non-bone painful lesions. There were no significant differences in pain response rate, the rate of the predominance of non-index pain or reductions in pain interference scores between the patients with non-bone lesions and those with bone metastases. Multivariable analysis showed that total radiation dose was an independent significant predictor of pain response in patients with non-bone painful lesions. This result was not robust to sensitivity analysis with Cox regression analysis.Conclusions
Higher total radiation dose seemed to be associated with a higher rate of pain response in patients with non-bone painful lesions. However, this finding was not robust to sensitivity analysis. Dose–response relationship should be investigated in clinical trials enrolling patients with these kinds of painful tumour. 相似文献20.
