ABSTRACT
Objective:To investigate the prognostic value of Onodera's prognostic nutrition index (PNI) before treatment in patients with cervical and upper thoracic esophageal squamous cell carcinoma (CUTESCC) undergoing definitive chemoradiotherapy (dCRT) and its predictive value in the occurrence of ≥ grade 2 radiation esophagitis (RE).Methods:The data of 163 CUTESCC patients eligible for inclusion criteria admitted to the Fourth Hospital of Hebei Medical University from January 2012 to December 2017 were retrospectively analyzed. The receiver operating characteristic (ROC) curve was used to calculate the best cut-off value of PNI for predicting the prognosis of patients. The prognosis of patients was analyzed by univariate and Cox multivariate analyses. Logistics binary regression model was adopted to analyze the risk factors of ≥ grade 2 RE in univariate and multivariate analyses. The significant factors in logistic multivariate analysis were used to construct nomogram for predicting ≥ grade 2 RE.Results:The optimal cut-off value of PNI was 48.57 [area under the curve (AUC): 0.653, P<0.001]. The median overall survival (OS) and progression-free survival (PFS) were 26.1 and 19.4 months, respectively. The OS ( χ2=6.900, P=0.009) and PFS ( χ2=9.902, P=0.003) of patients in the PNI ≥ 48.57 group ( n=47) were significantly better than those in the PNI < 48.57 group ( n=116). Cox multivariate analysis showed that cTNM stage and PNI were the independent predictors of OS ( HR=1.513, 95% CI: 1.193-1.920, P=0.001; HR=1.807, 95% CI: 1.164-2.807, P=0.008) and PFS ( HR=1.595, 95% CI: 1.247-2.039, P<0.001; HR=2.260, 95% CI: 1.439-3.550, P<0.001). Short-term efficacy was another independent index affecting PFS ( HR=2.072, 95% CI: 1.072-4.003, P=0.030). Logistic multivariate analysis showed that the maximum transverse diameter of the lesion ( OR=3.026, 95% CI: 1.266-7.229, P=0.013), gross tumor volume (GTV) ( OR=3.456, 95% CI: 1.373-8.699, P=0.008), prescription dose ( OR=3.124, 95% CI: 1.346-7.246, P=0.009) and PNI ( OR=2.072, 95% CI: 1.072-4.003, P=0.030) were the independent factors affecting the occurrence of ≥ grade 2 RE. These four indicators were included in the nomogram model, and ROC curve analysis showed that the model could properly predict the occurrence of ≥ grade 2 RE (AUC=0.686, 95% CI: 0.585-0.787). The calibration curve indicated that the actually observed values were in good agreement with the predicted RE. Decision curve analysis (DCA) demonstrated satisfactory nomogram positive net returns in most threshold probabilities. Conclusions:PNI before treatment is an independent prognostic factor for patients with CUTESCC who received definitive chemoradiotherapy. The maximum transverse diameter of the lesion, GTV, prescription dose and PNI are the risk factors for ≥ grade 2 RE in this cohort. Establishing a prediction model including these factors has greater predictive value.
ABSTRACT
Objective:To investigate the efficacy of camrelizumab combined with second-line therapy in patients with recurrent or metastatic esophageal squamous cell carcinoma (ESCC) in the real-world settings.Methods:Clinical data of 48 patients with esophageal cancer who met the inclusion criteria were retrospectively analyzed. The types of failure after first-line treatment, clinical efficacy, side effects and prognostic factors of second-line treatment were analyzed. SPSS 25.0 software was used for statistical analysis. Count data were expressed by composition ratio and analyzed by Chi-square test or Fisher's exact test. Survival analysis was conducted by Kaplan-Meier curve and log-rank test. Non-normally distributed data were recorded with the median, range and quartile. Results:There were 26, 14, and 4 cases of combined chemoradiotherapy, chemotherapy and radiotherapy in the treatment of second-line camrelizumab, and 4 cases received immunotherapy alone. The median duration of immunotherapy was 6 cycles (range, 2-39 cycles). After second-line treatment, the short-term efficacy of 17, 27 and 4 cases was partial remission (PR), stable disease (SD) and progressive disease (PD), respectively. The overall response rate (ORR) was 35.4% and disease control rate (DCR) was 91.7%. The 1- and 2-year OS rates were 42.9% and 22.5%, and 1- and 2-year PFS rates were 29.0% and 5.8%. The median OS and PFS were 9.0 months (95% CI=6.4-11.7) and 8.5 months (95% CI=1.5-5.6), respectively. Multivariate analysis showed that combined immunotherapy mode, number of cycles of immunotherapy and short-term efficacy were the independent prognostic indicators affecting OS in this group of patients ( HR=2.598, 0.222, 8.330, P=0.044, <0.001, <0.001). Lymphocyte count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), combined immunotherapy mode and short-term efficacy were the independent prognostic indicators affecting PFS in this group ( HR=3.704, 3.598, 6.855, 2.159, 2.747, P=0.009, 0.008, <0.001, 0.049, 0.012). Conclusions:Camrelizumab combined with second-line therapy can bring survival benefit to patients with recurrent or metastatic ESCC after first-line therapy, especially immunotherapy combined with chemoradiotherapy can significantly provide survival benefit. Peripheral blood inflammatory biomarkers are independent indicators affecting clinical prognosis of patients. Patients with better short-term efficacy also achieve better prognosis. The final conclusion remains to be validated by a large number of randomized controlled studies.
ABSTRACT
Objective:To analyze whether involved-field irradiation (IFI) was associated with improved survival and reduced treatment-related adverse events compared with elective nodal irradiation (ENI) in Chinese patients with esophageal squamous cell carcinoma receiving radiotherapy.Methods:Literature review was conducted from CNKI, Wanfang Data, PubMed, Embase, Web of Science and Cochrane Central databases (until July 31, 2022). Relevant data were collected according to the inclusion and exclusion criteria. Primary outcomes included overall survival (OS) rate and treatment-related adverse events. Secondary outcomes included progression-free survival (PFS) rate and local control rate (LCR). Risk of bias was assessed using the Cochrane Risk of Bias tool. The quality of the results was assessed by using the meta analysis of Evidence Evaluation and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methods.Results:A total of 7 articles with 918 patients were included of which 465 received IFI and 453 received ENI. The 1-, 2-, 3-and 5-year OS rates in the IFI group were not significantly different from those in the ENI group (1-year OS rate: RR=1.00, 95% CI=0.94-1.07, P=0.97, high certainty; 2-year OS rate: RR=1.01, 95% CI=0.90-1.13, P=0.90, high certainty; 3-year OS rate: RR=0.86, 95% CI=0.71-1.05, P=0.14, high certainty; 5-year OS rate: RR=0.76, 95% CI=0.42-1.37, P=0.36, low certainty). In the IFI group, patients with ≥grade 2 acute radiation esophagitis ( RR=0.71, 95% CI=0.58-0.87, P=0.001, high certainty), ≥grade 3 acute radiation esophagitis ( RR=0.39, 95% CI=0.24-0.64, P<0.001, high certainty) and ≥grade 2 acute radiation pneumonitis ( RR=0.72, 95% CI=0.52-0.99, P=0.04, high certainty) were significantly lower compared with those in the ENI group. However, no significant differences were observed in the incidence of ≥grade 3 late radiation esophagitis, ≥grade 3 acute radiation pneumonitis and ≥grade 3 late radiation pneumonitis between two groups. No significant differences were noted in the 1-, 2-, 3-PFS rates and LCR between two groups. Conclusions:For Chinese patients with esophageal squamous cell carcinoma, IFI and ENI yield similar efficacy in terms of OS, PFS and LCR. However, IFI has a lower incidence of ≥grade 2 acute radiation esophagitis, ≥grade 3 acute radiation esophagitis and ≥grade 2 acute radiation pneumonitis than ENI.
ABSTRACT
Neoadjuvant radiotherapy and chemotherapy combined with surgery is the standard treatment for patients with locally advanced esophageal cancer, which has been widely applied in clinical practice. Clinical efficacy has also been recognized by clinicians. However, even after the completion of neoadjuvant radiotherapy and subsequent surgical treatment, some patients still have local regional recurrence or distant metastasis in a short period of time. Among them, distant metastasis has become the main failure mode of patients undergoing surgery after neoadjuvant radiotherapy and chemotherapy, indicating that this treatment remains to be further improved. Based on the experience of patients with rectal cancer benefiting from total neoadjuvant therapy, the feasibility and implementation of total neoadjuvant therapy for locally advanced esophageal cancer were discussed in this article.
ABSTRACT
Objective:To evaluate the effects of high mobility group protein box 1 (HMGB1) on clinical prognosis of esophagus squamous cell carcinoma (ESCC) patients treated with chemoradiotherapy and the radiosensitivity of xenograft in nude mice.Methods:A total of 90 endoscopic biopsy specimens were obtained from ESCC patients treated with chemoradiotherapy. The expression level of HMGB1 was determined by immunohistochemical staining. High expression level was defined when staining was observed on ≥50% of the tumor cells. All patients were divided into the high expression group ( n=48) and low expression group ( n=42), and their survival information was retrospectively analyzed. Cell transfection was performed with the plasmid carrying human HMGB1-shRNA to knockdown HMGB1 expression in ECA109 cells and xenograft mouse models were established. The tumor volume and mass were calculated after irradiation with a dose of 15 Gy. The cell apoptosis in xenograft tissues were detected. Survival analysis was performed using Kaplan-Meier method. Univariate prognostic analysis was conducted by log-rank test. Intergroup comparison was performed by analysis of variance (ANOVA). Results:The expression level of HMGB1 was significantly associated with gross tumor volume, longest diameter of tumor, T staging and distant metastasis ( χ2=9.663, 5.625, 4.068, 7.146, all P<0.05). In the low expression group, the overall survival (OS) ( χ2=4.826, P=0.028), progression-free survival (PFS) ( χ2=4.390, P=0.036) were longer compared with that in the high expression group. Further analysis of HMGB1-high expression patients showed that the radiation dose and the combination of chemoradiotherapy did not significantly affect the OS or PFS of ESCC patients. We observed that knockdown of HMGB1 slowed the growth rate of xenograft, decreased the tumor volume and increased the apoptosis rate after irradiation. Conclusions:ESCC patients with high expression level of HMGB1 obtain poor prognosis after chemoradiotherapy, which can be enhanced by increasing the sensitivity to radiotherapy and chemotherapy. HMGB1 knockdown can effectively increase the radiosensitivity of xenograft in ESCC nude mice.
ABSTRACT
Objective:To analyze the local recurrence patterns after concurrent chemoradiotherapy (CCRT) for thoracic esophageal squamous cell carcinoma (ESCC) through image fusion, and to explore the risk factors of local recurrence and its relationships with dosimetric indices.Methods:A retrospective analysis was conducted for 209 thoracic ESCC patients who received radical CCRT in Fourth Hospital of Hebei Medical University during 2016-2019. For the patients diagnosed as the local recurrence of esophageal lesions, their CT images were fused with the original planning CT images using image registration software to identify the recurrence sites. Through 1∶1 propensity score matching (PSM) of the clinal data of patients with local recurrence (the recurrence group, nbefore = 81, nafter = 62) and those without local recurrence (the recurrence-free group, nbefore = 128, nafter=62), the dose and volume parameters of the treatment plans for the two groups were compared. Univariate and multivariate analyses were conducted using the Kaplan-Meier method and the Cox regression model to analyze the factors affecting the overall survival (OS), progression-free survival (PFS), and recurrence-free survival (RFS). Results:All patients had 1-, 3-, and 5-year OS rates of 80.9%, 42.6%, and 33.0%, respectively, 1-, 3-, and 5-year PFS rates of 67.9%, 34.0%, and 27.9%, respectively, and 1-, 3-, and 5-year RFS rates of 71.3%, 39.2%, and 30.5%, respectively. T stage, N stage, and radiation dose were independent prognostic factors for the OS, PFS, and RFS ( HR = 1.42-1.87, P < 0.05) of the patients, respectively. Among 68 patients with local recurrence, 62 cases (91.2%) suffered recurrence within the gross tumor volume (GTV). The dose and volume parameters of patients with local recurrence, such as GTV- D95%, clinical target volume (CTV)- D95%, GTV- D50%, CTV- D50%, and planning target volume (PTV)- D50%, GTV- V60, CTV- V60, and PTV- V60, were significantly lower than those of patients free from the local recurrence ( t=1.90-2.15, P < 0.05). Conclusions:Local recurrence of patients with thoracic ESCC after radical CCRT occurs mainly within the GTV. Increasing radiation doses may contribute to their survival benefits. The D50% for each target volume in the radiotherapy plan may be related to local recurrence, and it is necessary to conduct further research.
ABSTRACT
Small cell lung cancer (SCLC) is highly malignant, aggressive and prone to brain metastasis. Several guidelines recommend prophylactic cranial irradiation (PCI) as the standard treatment for SCLC patients who have achieved complete remission after initial systemic treatment. However, in the modern era, magnetic resonance imaging (MRI) has been commonly applied in the diagnosis of brain metastasis, while radiotherapy combined with immunotherapy and molecular targeted therapy are widely adopted in the treatment of lung cancer. The value of PCI in SCLC has been questioned and challenged. In addition, the application of hippocampal avoidance and drugs to reduce the damage of neurocognitive function after PCI has also become a research hotspot. In this article, the research progress on PCI was reviewed with the latest literature, aiming to provide reference for selecting the most suitable individualized treatment for patients receiving PCI.
ABSTRACT
Objective:To investigate the diagnosis of malignancy with upper limb lymphedema as the initial sign and symptoms.Methods:Clinical data of 6 patients with malignant lymphedema admitted at the Department of Lymphatic Surgery, Beijing Shijitan Hospital, Capital Medical University, from May 2007, to Dec 2018 were retrospectively analyzed.Results:The age of these 6 patients ranged from 50 to 78 years. The time from the occurrence of lymphedema to the diagnosis of malignant tumors ranged from 1 month to 15 years. Limb swelling occurred in all 6 cases. Local lymphadenopathy occurred in 4 cases and limb paresthesia occurred in 2 cases. Pathological diagnosis showed that the tumor originated from epithelial tissue in 3 cases, mesenchymal tissue in 2 cases and lymphatic system in 1 case. Pathological diagnosis showed that the tumor originated from epithelial tissue in 3 cases, mesenchymal tissue in 2 cases and lymphatic system in 1 case.Conclusions:To avoid delays in the diagnosis and therapy of malignant lymphedema, physicians should actively look for signs or symptoms of lymphedema during the follow-up period and promptly manage patients developing problems.
ABSTRACT
Objective:To investigate the clinical features, diagnosis, treatment and prognosis of adult cervical lymphangioma.Methods:Twenty-five cases of adult cervical lymphangioma admitted at Department of Lymphatic Surgery of Beijing Shijitan Hospital from Feb 2017 to Jun 2020 were retrospectively analyzed.Results:Among the 25 cases,there were 5 males and 20 females, aged from 18 to 58 years. Radionuclide lymphoscintigraphy performed in 25 cases, increased radioactivity in the neck tumor area was seen in 8 cases; Direct lymphangiography performed in 17 cases,outlet obstruction of cervical thoracic duct was found in 14 cases. Twenty one cases were treated by operation and followed up for 6-47 months. No recurrence was found; 4 cases abandoned surgery, 1 case was lost to follow-up, and the other 3 cases were followed up for 16-48 months with tumor progresses.Conclusions:Adult cervical lymphangioma is lymphangiomalformation disease. Total resection of the tumor and avoiding damage to the thoracic duct is the key for successful management.
ABSTRACT
Objective:To investigate the long-term prognosis and failure mode of patients with esophageal squamous cell carcinoma who achieved clinical complete remission (cCR) after receiving radical radio (chemo) therapy.Methods:Clinical data of 183 patients with esophageal squamous cell carcinoma eligible for inclusion criteria who received treatment in our hospital from January 2009 to December 2012 were retrospectively analyzed. The factors that affected the long-term prognosis of patients were identified, and the failure mode of cCR patients and the prognosis after failure were analyzed. SPSS 19.0 statistical software was used for data analysis.Results:As of the follow-up date, the 1-, 3-, 5-, and 10-year overall survival (OS) rates and disease-free survival (DFS) rates of the entire group were 83.1%, 53.4%, 36.2%, 12.8% and 68.9%, 45.9%, 30.5%, 12.0%, respectively. The median OS and DFS were 41.3 months and 33.4 months. The results of multivariate analysis showed that cT staging, cN staging and prescribed dose were the independent factors affecting the OS ( P=0.001, <0.001, 0.003); hoarseness, lesion length, cT staging, cN staging and prescribed dose were the independent factors that affected the DFS ( P=0.002, 0.033, 0.009, <0.001, 0.003). In the whole group, 72 cases (39.3%) had local regional recurrence, 58 cases (31.7%) had distant metastasis, and 26 cases (14.2%) had local regional recurrence with distant metastasis. Among 104 patients after treatment failure, the prognosis of patients receiving salvage treatment was significantly better than that of their counterparts receiving maintenance treatment ( χ2=39.153, P<0.001). Conclusions:The long-term prognosis of patients with esophageal squamous cell carcinoma who achieved cCR after receiving radical radio (chemo) therapy is still unsatisfactory. Clinically, it is necessary to strengthen the clinical observation and follow-up of these patients. The main treatment failure mode of cCR patients is local regional recurrence. Active salvage treatment can significantly improve clinical prognosis of these patients.
ABSTRACT
Objective:To investigate the recurrence-free survival (RFS) and influencing factors of intensity-modulated radiotherapy±chemotherapy (IMRT±C) for the upper thoracic esophageal cancer.Methods:The medical records of 168 patients with cervical and upper thoracic esophageal cancer who met the inclusion criteria from January 2011 to December 2015 were retrospectively analyzed. The RFS was calculated by the Kaplan-Meier method. Multivariate prognostic analysis was performed by Cox models. The recurrence factors were identified by the Logistics model. Results:The 1-, 3-, and 5-year RFS rates were 67.8%, 38.0%, and 20.4%, respectively, and the median RFS was 21.9 months. The locoregional recurrence rate was 47.6%(80/168). The recurrence sites were local esophagus ( n=63), regional lymph nodes ( n=7), and local esophagus+ regional lymph node recurrence ( n=10). Multivariate analysis showed that hoarseness, cTstaging, combined with chemotherapy, 95%PTV 1 exposure dose and GTV average exposure dose were the influencing factors of RFS ( P=0.029, <0.001, 0.031, 0.038, 0.020). Logistics model showed that cTstaging, cNstaging, short-term efficacy, irradiationmethod, GTV maximum transverse diameter and PTV average exposure dose were the influencing factors of recurrence ( P=0.046, 0.022, 0.001, <0.001, 0.012, 0.001). Conclusions:Patients with cervical and upper thoracic esophageal cancer treated with radical IMRT combined with/without chemotherapy have a higher locoregional recurrence rate, and the recurrence rate is mainly the esophagus. The independent factors that affect RFS are different from the risk factors of recurrence.
ABSTRACT
Objective:To investigate the effects of the systemic immune-inflammation index (SII)on the long-term survival in esophageal cancer patients treated with radiotherapy.Methods:Aretrospective review was conducted for the clinical data of 303 patients with esophageal squamous cell carcinoma(ESCC)who received radical radiotherapy in the Fourth Hospital of Hebei Medical University from 2011 to 2017. These patients were divided into a high-SII group and a low-SII group according to their SII before radiotherapy. The correlation between SII and survival was determined using the Kaplan-Meier method and Cox regression model. Propensity score matching (PSM) was applied to reduce bias from measured confounding.Results:The SII of patients before radiotherapy was correlated significantly with T stage ( χ2=8.015, P=0.018) and TNM stage ( χ2=8.619, P=0.013). The 1-, 3-, 5-year overall survival (OS) rates in the high-SII group were 64.9%, 27.1%, and 19.4%, respectively. They were significantly lower than those in the low-SII group, which were 84.9%, 43.9%, and 30.5%, respectively (χ 2=13.443, P<0.001). The 1-, 3-, 5-year progression-free survival (PFS) rates in the high-SII group were 46.4%, 20.3%, and 13.3%, respectively. They were significantly lower than those in the low-SII group, which were 67.8%, 34.8%, and 26.5%, respectively (χ 2=12.383, P<0.001). The multivariate analysis indicated that the independent factors influencing the OS and PFS included T stage, lymph node metastasis, chemotherapy, and SII.After PSM was applied, the OS and PFS in the high-SII group were still lower than those in the low-SII group(χ 2OS=4.264, P=0.039; χ 2PFS=5.376, P=0.020), and the multivariate analysis showed that SII was a significant predictor for OS and PFS( HROS=1.357, P=0.037; HRPFS=1.393, P=0.022). Conclusions:SII is a significant independent influencing factor of the OS and PFS inESCC patients treated with received radiotherapy. Based on simple and inexpensive standard laboratory measurements, SII can be a promising marker for ESCC patients.
ABSTRACT
Objective:To investigate the relationship between systemic immune-inflammation index (SII) and the prognosis of esophageal cancer patients treated with radical radiotherapy and to predict the prognosis of the patients using the SII combined with clinical staging.Methods:A retrospective analysis was conducted for 248 patients with esophageal cancer who were admitted to the Department of Radiotherapy in the Fourth Hospital of Hebei Medical University between 2014 and 2016. These patients included 146 males and 102 females, with a median age of 67 years. Among them, 134 patients received concurrent chemotherapy and 114 patients received radiotherapy alone. The SII before radiotherapy was defined as platelet count × neutrophil count/lymphocyte count. The patients were divided into a low-SII group and a high-SII group according to the optimal cutoff value of pretreatment SII determined by the receiver operating characteristics (ROC) curve. Survival analysis was calculated using the Kaplan-Meier method, and the Cox proportional hazards model was used for multivariate analysis. For these patients, the prognosis effects and the predictive value for survival of different SII levels combined with TNM staging were compared.Results:According to the ROC curves, the optimal cutoff value of SII before radiotherapy was 740.80. Based on this number, the patients were divided into a low-SII group (< 740.80, 150 cases) and a high-SII group (≥ 740.80, 98 cases). The objective response rate of the low-SII group was significantly higher than that of the high-SII group (86.0% vs 75.5%, χ2=4.39, P=0.036). The 1-, 3-, and 5-year overall survival (OS) rates of the low-SII group were 78.6%, 45.6%, and 32.3%, respectively. These rates were significantly higher than the corresponding rates of the high-SII group, which were 71.0%, 28.3%, and 16.4% ( χ2=11.22, P=0.001), respectively. Moreover, the 1-, 3- and 5-year progression-free survival (PFS) rates of the low-SII group were 67.0%, 36.9%, and 32.0%, respectively. Again, these rates were significantly higher than those of the high-SII group, which were 45.5%, 17.5%, and 12.5% ( χ2=15.38, P < 0.001), respectively. Multivariate analysis showed that TNM staging, treatment method, and SII were independent prognostic factors for OS and PFS ( HR=1.39-1.60, P<0.05). Patients with low SII and early clinical staging had a better prognosis than other subgroups ( χ2=13.68, 13.43, P=0.001). The area under curve (AUC) of SII combined with TNM staging (0.70) was higher than that of SII (0.63) and TNM staging (0.62) ( Z=2.48, 2.57, P < 0.05). Conclusions:Pretreatment SII has a high predictive value for the prognosis of esophageal cancer after radiotherapy, and higher SII indicates a worse prognosis. Thus, combining SII with TNM staging can improve the prediction accuracy of the prognosis of esophageal cancer patients.
ABSTRACT
Objective:To improve the understanding of the relationship between lymphedema and retroperitoneal fibrosis (RPF).Methods:Four cases with lymphedema and RPF in Beijing Shijitan Hospital Capital Medical University were reported. The diagnosis and treatment were analyzed and discussed.Results:All four patients had lymphedema onset and imaging showed suspicious RPF. One case of non-Hodgkin's lymphoma was confirmed by lymph node biopsy. The malignant lesions were excluded in the other two cases by pathology or positron emission tomography (PET)/computerized tomography (CT). They were proved to be idiopathic retroperitoneal fibrosis after treatment with glucocorticoid combined immunosuppressive agents. Another case was systemic amyloidosis mimicking retroperitoneal fibrosis.Conclusion:Lymphatic involvement in RPF is relatively rare, and the possibility of RPF should be considered when patients develop lymphedema. Even if the initial diagnosis is RPF, we should be wary of tumors or other diseases. Imaging examination should be performed, and tissue biopsy should be used if necessary, so as to facilitate early diagnosis and treatment and improve the prognosis of patients.
ABSTRACT
Objective:To evaluate peritoneovenous shunt for treatment of refractory chylous ascites.Methods:The clinical data of 40 patients with refractory chylous ascites treated by peritoneovenous shunt procedure at Department of Lymphatic Surgery, Beijing Shijitan Hospital, Capital Medical University from May 2008 to Aug 2020 were retrospectively analyzed.Results:Patients'postoperative weight [(57.8±13.2) kg] was significantly lower than that of preoperative weight [(65.9±13.1) kg]. Postoperative abdominal circumference significantly reduced [(82.0±9.8) cm vs. (94.3±10.8) cm]. Average postoperative 24-hour urine output was significantly higher than that before operation [2 250 (1 650, 3 300) ml vs. 750 (500, 1 000) ml]. Platelet count and fibrinogen decreased after operation; prothrombin time (PT) prolonged; the change of time of activated partial thromboplastin (APTT) was not statistically significant ( P=0.506). Postoperative aspartate aminotransferase (AST), urea, and creatinine decreased; whereas alanine aminotransferase (ALT) ( P=0.154), total protein ( P=0.350), and albumin ( P=0.113) remained unchanged. 35 patients got follow-up, 29 deceased. The survival time with tube was 16 (7,37) months; 6 cases survived, the survival time with tube was 28 (6,124) months. Conclusions:Peritoneovenous shunt is a palliative surgery improving the quality of life of patients with refractory chylous ascites.
ABSTRACT
Objective:To investigate the relationship between Onodera′s prognostic nutritional index (PNI) and prognosis of patients with esophageal squamous cell carcinoma (ESCC) after definitive chemoradiotherapy or radiotherapy, aiming to provide a convenient, effective and accurate predictive indicator for evaluating the long-term survival of patients after treatment.Methods:Clinical data of 231 ESCC patients treated with definitive chemoradiotherapy or radiotherapy at the Fourth Hospital of Hebei Medical University from 2013 to 2015 were retrospectively analyzed. The PNI values of each patient at different radiotherapy periods were calculated and the ROC curve was used to determine the optimal cutoff value of PNI before radiotherapy, 231 patients were divided into the better-nourishment group ( n=86) and worse-nourishment group ( n=145). Kaplan- Meier method was used for survival analysis. Cox proportional hazards model was utilized to analyze the relationship between different nutritional status and prognosis. The short-term clinical efficacy and incidence of acute toxicities were statistically compared between two groups. Results:The mean values of PNI before, at week 3, week 6 and 1 month after radiotherapy were48.68±5.08, 39.68±4.87, 43.74±4.89 and48.31±4.92, respectively. The optimal cutoff value of pretreatment PNI was 49.25, the area under the curve (AUC) was 0.655, the sensitivity and specificity were 68.6% and 60.9%, respectively. The 5-year overall survival (OS) and progression-free survival (PFS) rates in the better-nourishment group (PNI≥49.25) were 36.0% and 31.3%, significantly better than 19.3% and 18.6% in the worse-nourishment group (PNI<49.25)( P=0.001, P=0.039). Multivariate analysis showed PNI before the therapy was an independent prognostic factor for OS ( P=0.021). Stratified analysis demonstrated that Stage Ⅰ/Ⅱ and concurrent chemotherapy patients in the better-nourishment group all obtained significantly better OS than their counterparts in the worse-nourishment group ( P=0.007, P=0.004). In addition, the objective response rate in the better-nourishment group was significantly higher than that in the worse-nourishment group ( P=0.047), whereas the incidence of ≥3 grade radiation esophagitis was lower than that in the worse-nourishment group ( P=0.060). Conclusions:Pretreatment PNI is a convenient and reliable indicator for predicting the long-term survival of ESCC patients after definitive chemoradiotherapy or radiotherapy. Patients with higher PNI have relatively better prognosis and radiotherapy tolerance, especially in those with early stage or concurrent chemotherapy.

Objective:To explore the benefit groups of patients with locoregional recurrence of esophageal thoracic squamous cell carcinoma who received radiotherapy or chemoradiotherapy with different patterns of irradiation.Methods:Clinical data of 344 esophageal thoracic squamous cell carcinoma patients with postoperative recurrence who received intensity conformal radiotherapy or concurrent chemoradiotherapy in the Fourth Hospital of Hebei Medical University from 2009 to 2014 were retrospectively analyzed. The distribution of recurrence sites and prognostic factors were analyzed. A stratified analysis was carried out on the benefit groups of patients receiving the elective nodal irradiation (ENI) and involved field irradiation (IFI).Results:276 cases (80.2%) recurred at a single site and 68 cases (19.8%) recurred at more than two sites. The follow-up rate was 96.2%. The 1-, 3-and 5-year overall survival rates were 53.6%, 22.6% and 16.4%, respectively, with a median of 12.8 months (95% CI: 11.3-14.3 months). The 1-, 3-and 5-year local recurrence-free survival rates were 46.5%, 16.9% and 12.0%, respectively, with a median of 11.0 months (95% CI: 9.6-12.4 months). The 1-, 3-and 5-year progression-free survival rates were 39.8%, 11.3% and 6.7%, respectively, with a median of 7.9 months (95% CI: 5.8-10.0 months). Multivariate analysis showed that gender, the log odds of metastatic lymph nodes (LODDS) and the number of chemotherapy cycles were the independent prognostic factors ( P=0.003, <0.001, <0.001). Subgroup univariate analysis demonstrated that patients with an esophageal lesion length<5.0 cm, N 0 stage, the number of surgically-dissected lymph nodes of ≤9, the number of postoperative positive lymph node metastasis site of 0, and LODDS≤0.030 obtained benefits from ENI ( P=0.032, 0.012, 0.001, 0.012 and 0.014). Patients with the number of surgically-dissected lymph nodes of ≥16 achieved benefits from IFI ( P=0.035). Conclusions:Radiotherapy is an effective treatment mode for patients with local recurrence after esophageal cancer surgery. For patients with preoperative esophagography showing shorter esophageal lesions, earlier postoperative pathological N stage, lower LODDS score, and fewer surgically-dissected lymph nodes probably obtain more benefits from ENI than IFI. However, patients with more surgically-dissected lymph nodes may obtain more benefit from IFI compared with ENI.
ABSTRACT
Objective:To evaluate the effects of different irradiation doses on postoperative local recurrence in patients with esophageal cancer after radio (chemo) therapy.Methods:Clinical data of 331 esophageal cancer patients presenting with postoperative local recurrence admitted to our hospital from 2009 to 2014 were collected. The recurrence site, the effects of different radiotherapy doses on the prognosis of patients and the independent prognostic factors were retrospectively analyzed. The survival rate was calculated by Kaplan-Meier method. Univariate prognostic analysis was performed by log-rank test. Multivariate prognostic analysis was conducted by Cox proportional hazard regression model.Results:The 1-, 3-and 5-year overall survival rates were 54.3%, 23.2% and 16.6%, respectively. The median overall survival was 13.4 months (95% CI: 11.7-15.0). The median survival of patients with radiotherapy doses< 60 Gy and ≥60 Gy was 10.8 and 13.9 months ( P=0.013). Stratified analysis showed that patients with age< 60 years, no smoking history, no drinking history, no family history, upper thoracic segment, left thoracotomy, N 0 staging, log odds of positive lymph nodes (LODDS)< 0.030, recurrence time ≥ 13.1 months and recurrence site ≥ 2 had better prognosis when receiving radiotherapy dose ≥ 60 Gy ( P=0.038, 0.033, 0.001, 0.003, 0.018, 0.010, 0.041, 0.039, 0.043 and 0.007). Moreover, the short-term clinical efficacy of patients treated with ≥60 Gy dose was significantly better than that of those with<60 Gy dose ( P<0.001), which did not increase the incidence of ≥grade 2 radiation-induced gastritis ( P=0.977) or radiation-induced pneumonitis ( P=0.444). Cox multivariate analysis showed that the LODDS size, prescription dose and short-term efficacy were the independent factors affecting clinical prognosis of patients ( P=0.006, 0.008 and<0.001). Conclusions:The recommended dose for esophageal cancer patients with local recurrence after radiotherapy (chemotherapy) is greater than or equal to 60 Gy. The results of this study need to be confirmed by prospective studies with a large sample size.
ABSTRACT
Objective:To analyze the therapeutic effects and prognosis after radiotherapy (chemotherapy) of patients with postoperative recurrent esophageal cancer.Methods:This study analyzed 501 patients with postoperative recurrent esophageal cancer who were treated in the Radiotherapy Department of the Fourth Hospital of Hebei Medical University and met enrollment conditions. Among them, 274 patients received concurrent chemotherapy and radiotherapy. The analyses in this study focused on the survival after the retreatment, postoperative recurrence patterns, prognosis of retreatment, and prognostic factors affecting the retreatment. Meanwhile, statistical analysis was conducted using the software SPSS Statistics 19.0.Results:The time of postoperative recurrence was 0.3-87.4 months, with a median number of 11.6 months. The median survival time was 12.1 months after the retreatment. Among all the patients, 344 patients suffered from only local recurrence, while the remaining 157 patients experienced distant metastasis. According to multivariate analysis result, independent prognostic factors included gender, pN stage, lymph node positive logarithmic ratio (LODDS), the number of chemotherapy cycles, time of recurrence, and distant metastasis ( P < 0.05). Meanwhile, prognostic factors affecting the 344 patients with only local recurrence included the time of recurrence, the number of chemotherapy cycles, and prescription dose ( χ2=22.605, 13.957, 10.446; P< 0.05). The remaining 157 patients suffered from distant metastasis. The 1-, 3-, and 5-year survival rates of them were 43.3%, 9.1%, and 5.5%, respectively, and those of the patients with only local recurrence were 53.6%, 22.6%, and 16.4%, respectively. The differences were statistically significant (χ 2=10.786, P< 0.05). Conclusions:Radiotherapy (chemotherapy) is safe and effective for the treatment of recurrent esophageal cancer. However, it features poor prognosis for male patients with a late pN stage, a high LODDS, the number of chemotherapy cycles ≤ 2, the time of recurrence≤ 24 months, and distant metastasis.
ABSTRACT
Objective:To study the prognostic impact of prognostic nutritional index (PNI) before radiotherapy in clinical stage Ⅲ esophageal cancer patients.Methods:We retrospectively reviewed 125 esophageal cancer patients with clinical stage Ⅲ undergoing definitive radiotherapy in Fourth Hospital of Hebei Medical University from 2013 to 2017. The PNI and nutritional risk index (NRI) were calculated before radiotherapy. The optimal cutoff value of PNI was determined by time-dependent receiver operating characteristics (ROC) at 49.925.The patients were divided into low PNI group(PNI<49.925) and high PNI group (PNI≥49.925). Based on NRI, the patients were divided into normal NRI group (NRI≥100) and abnormal NRI group (NRI<100). Kaplan-Meier method was used to calculate the overall survival (OS) and progression-free survival (PFS) and to perform univariate analysis. The mutlivariate analysis was performed by Cox regression model.Results:PNI was positively correlated with hemoglobin ( r=0.505, P<0.001) and NRI ( r=0.594, P<0.001). The 1-, 3- and 5-year OS rates in the low PNI group were significantly lower than those of the high PNI group (67.5%, 27.3%, 11.4% vs. 85.4%, 45.8%, 27.4%, respectively, χ2=8.569, P<0.05). Moreover, the 1-, 3- and 5-year PFS rates in the low PNI group were obviously higher than those in the high PNI group (59.7%, 23.2%, 4.9% vs. 79.2%, 35.4%, 24.9%, respectively, χ2=6.715, P<0.05). Univariate analysis showed that GTV, radiotherapy dose, chemotherapy, albumin, NRI and PNI were significantly correlated with OS and PFS (OS: χ2=6.822, 4.326, 4.474, 13.123, 8.846, 8.569, P<0.05: PFS: χ2=7.869, 4.636, 5.874, 10.911, 8.544, 6.715, P<0.05). Multivariate analysis showed that GTV, radiotherapy dose and PNI were independent prognostic factors for OS ( P<0.05). And GTV, radiotherapy dose, chemotherapy and PNI were independent prognostic factors for PFS ( P<0.05). Conclusions:The PNI before radiotherapy is a significant and independent predictor for survival of clinical stage Ⅲ esophageal cancer patients. Based on simple and inexpensive standard laboratory measurements, PNI could be a promising prognostic biomarker for esophageal cancer patients.
