Stage IV malignant transformation of mature cystic teratoma palliatively treated with concurrent chemoradiotherapy:A case report

BACKGROUND Malignant transformation(MT)of mature cystic teratoma(MCT)has a poor prognosis,especially in advanced cases.Concurrent chemoradiotherapy(CCRT)has an inhibitory effect on MT.CASE SUMMARY Herein,we present a case in which CCRT had a reduction effect preoperatively.A 73-year-old woman with pyelonephritis was referred to our hospital.Computed tomography revealed right hydronephrosis and a 6-cm pelvic mass.Endoscopic ultrasound-guided fine-needle biopsy(EUS-FNB)revealed squamous cell carci-noma.The patient was diagnosed with MT of MCT.Due to her poor general con-dition and renal malfunction,we selected CCRT,expecting fewer adverse effects.After CCRT,her performance status improved,and the tumor size was reduced;surgery was performed.Five months postoperatively,the patient developed dis-semination and lymph node metastases.Palliative chemotherapy was ineffective.She died 18 months after treatment initiation.CONCLUSION EUS-FNB was useful in the diagnosis of MT of MCT;CCRT suppressed the disea-se and improved quality of life.

Survival benefit of concurrent chemoradiotherapy for advanced ampulla of Vater cancer

BACKGROUND Currently,there is no standard adjuvant therapy for patients with resected ampulla of Vater(AoV)cancer.AIM To evaluate the effectiveness of adjuvant concurrent chemoradiotherapy(CCRT)in patients with advanced AoV cancer who underwent curative resection.METHODS This single-centered,retrospective study included 29 patients with advanced AoV cancer who underwent pancreaticoduodenectomy between 2006 and 2018.The impact of CCRT on advanced AoV cancer was analyzed.RESULTS The 1-,3-,and 5-yr recurrence-free survival(RFS)rates for patients with advanced AoV cancer were 82.8%,48.3%,and 40.8%,respectively,and the overall survival(OS)rates were 89.7%,62.1%,and 51.7%,respectively.Lymphovas-cular invasion was found to be a significant risk factor for RFS and OS in patients with advanced AoV cancer in the univariate analysis,whereas T stage and lymph node metastasis were significantly associated with OS in the multivariate analysis.Compared to the patients who did not receive adjuvant CCRT,those who received adjuvant CCRT did not show statistically significant improvements in the RFS and OS,although they had a significantly lower average age and significantly higher platelet-to-lymphocyte ratio.CONCLUSION Adjuvant CCRT did not improve survival outcomes in patients with advanced AoV cancer.These findings contribute to existing knowledge on the effectiveness of CCRT in this patient population and provide important insights for clinical decision-making.

Programmed cell death 1 inhibitor sintilimab plus concurrent chemoradiotherapy for locally advanced pancreatic adenocarcinoma

BACKGROUND Pancreatic adenocarcinoma,a malignancy that arises in the cells of the pancreas,is a devastating disease with unclear etiology and often poor prognosis.Locally advanced pancreatic cancer,a stage where the tumor has grown significantly but has not yet spread to distant organs,presents unique challenges in treatment.This article aims to discuss the current strategies,challenges,and future directions in the management of locally advanced pancreatic adenocarcinoma(LAPC).AIM To investigate the feasibility and efficacy of programmed cell death 1(PD-1)inhibitor sintilimab plus concurrent chemoradiotherapy for LAPC.METHODS Eligible patients had LAPC,an Eastern cooperative oncology group performance status of 0 or 1,adequate organ and marrow functions,and no prior anticancer therapy.In the observation group,participants received intravenous sintilimab 200 mg once every 3 wk,and received concurrent chemoradiotherapy(concurrent conventional fractionated radiotherapy with doses planning target volume 50.4 Gy and gross tumor volume 60 Gy in 28 fractions and oral S-140 mg/m2 twice daily on days 1-14 of a 21-d cycle and intravenous gemcitabine 1000 mg/m2 on days 1 and 8 of a 21-d cycle for eight cycles until disease progression,death,or unacceptable toxicity).In the control group,participants only received concurrent chemoradiotherapy.From April 2020 to November 2021,64 participants were finally enrolled with 34 in the observation group and 30 in the control group.RESULTS Thirty-four patients completed the scheduled course of chemoradiotherapy,while 32(94.1%)received sintilimab plus concurrent chemoradiotherapy with 2 patients discontinuing sintilimab in the observation group.Thirty patients completed the scheduled course of chemoradiotherapy in the control group.Based on the Response Evaluation Criteria in Solid Tumors guidelines,the analysis of the observation group revealed that a partial response was observed in 11 patients(32.4%),stable disease was evident in 19 patients(55.9%),and 4 patients(11.8%)experienced progressive disease;a partial response was observed in 6(20.0%)patients,stable disease in 18(60%),and progressive disease in 6(20%)in the control group.The major toxic effects were leukopenia and nausea.The incidence of severe adverse events(AEs)(grade 3 or 4)was 26.5%(9/34)in the observation group and 23.3%(7/30)in the control group.There were no treatment-related deaths.The observation group demonstrated a significantly longer median overall survival(22.1 mo compared to 15.8 mo)(P<0.05)and progression-free survival(12.2 mo vs 10.1 mo)(P<0.05)in comparison to the control group.The occurrence of severe AEs did not exhibit a statistically significant difference between the observation group and the control group(P>0.05).CONCLUSION Sintilimab plus concurrent chemoradiotherapy was effective and safe for LAPC patients,and warrants further investigation.

Radiotherapy with neoadjuvant chemotherapy versus concurrent chemoradiotherapy for ascending-type nasopharyngeal carcinoma:a retrospective comparison of toxicity and prognosis

Background:In the era of intensity?modulated radiotherapy(IMRT),the role of neoadjuvant chemotherapy(NACT)in treating ascending?type nasopharyngeal carcinoma(NPC)is under?evaluated.This study was to compare the efficacy of NACT followed by IMRT(NACT+RT)with the efficacy of concurrent chemoradiotherapy(CCRT)on ascending?type NPC.Methods:Clinical data of 214 patients with ascending?type NPC treated with NACT+RT or CCRT between Decem?ber 2009 and July 2011 were analyzed.Of the 214 patients,98 were treated with NACT followed by IMRT,and 116 were treated with CCRT.The survival rates were assessed using Kaplan–Meier analysis,and the survival curves were compared using a log?rank test.Results:The 4?year overall survival,locoregional failure?free survival,distant failure?free survival,and failure?free sur?vival rates were not significantly different between the two groups(all P>0.05).However,patients in the CCRT group exhibited more severe acute adverse events than did patients in the NACT+RT group during radiotherapy,includ?ing leukopenia(30.2%vs.15.3%,P=0.016),neutropenia(25.9%vs.11.2%,P=0.011),and mucositis(57.8%vs.40.8%,P=0.028).After radiotherapy,patients in the CCRT group exhibited significantly higher rates of xerostomia(21.6%vs.Conclusions:The treatment outcomes of the NACT+RT and CCRT groups were similar;however,CCRT led to higher rates of acute and late toxicities.NACT+RT may therefore be a better treatment strategy for ascending?type NPC.

Concurrent chemoradiotherapy for cervical cancer： background including evidence-based data, pitfalls of the data, limitation of treatment in certain groups

Concurrent chemoradiotherapy （CCRT） is regarded as the standard treatment for locally advanced uterine cervical cancer （LACC）, including stage Ib2-IVa disease [International Federation of Gynecology and Obstetrics （FIGO） staging]. However, approximately a third of eligible patients in previous studies died of LACC despite receiving CCRT. The therapeutic significance of CCRT alone in stage Ⅲ-IVa disease has not yet been confirmed. Effective treatment of some LACC is beyond the scope of CCRT. The objective of the present review is to highlight some challenging work aimed at overcoming this seemingly intractable disease. CCRT with increased peak concentrations of cisplatin （CDDP）, surgery following CCRT, adjuvant chemotherapy （CT） following CCRT, and neoadjuvant CT followed by CCRT are strategies expected to enhance the therapeutic efficacy of CCRT. If patients with LACC were divided into those with low-risk or high-risk systemic disease or prognoses, novel strategies should be assessed in the group with high-risk disease.

PhaseⅡstudy of induction chemotherapy followed by concurrent chemoradiotherapy with raltitrexed and cisplatin in locally advanced nasopharyngeal carcinoma

Objective:For locally advanced nasopharyngeal carcinoma(LA-NPC)patients,high incidences of distant metastases and severe treatment related toxicities are the main obstacles needed to be overcome.Raltitrexed,a specific thymidylate synthase inhibitor with a convenient administration schedule,has an acceptable and manageable toxicity,and possesses radio-sensitizing properties.To investigate the efficacy and safety of raltitrexed and cisplatin induction chemotherapy and concurrent chemoradiotherapy(IC+CCRT)in patients with LA-NPC,a phaseⅡclinical study was conducted.Methods:Sixty eligible patients with LA-NPC were enrolled into this study.A raltitrexed-cisplatin combination was used as part of an IC+CCRT regimen.Raltitrexed-cisplatin IC was given once every 3 weeks(q3 w)for two cycles,followed by raltitrexed-cisplatin based CCRT q3 w for two cycles.Intensity-modulated radiotherapy(IMRT)was given for all enrolled patients.Results:All patients were included in survival analysis according to the intent-to-treat principle.The objective response rate(ORR)3 months after treatment was 98%.The 2-year overall survival(OS)rate was 92%.The median relapse-free survival(RFS)time was 30.5[95%confidence interval(95%CI),28.4-32.3]months.The 2-year RFS rate was 85%.The 2-year local failure-free survival(LFFS)rate was 97%and the 2-year distant metastasis-free survival(DMFS)rate was 88%.Acute toxicities were mostly grade 2 and 3 reactions in bone marrow suppression,gastrointestinal side effect and oropharyngeal mucositis.Only two patients occurred grade 4 acute toxicities,one was bone marrow suppression and the other was dermatitis radiation.Conclusions:The combination of raltitrexed and cisplatin has a comparable efficacy to those in standard firstline therapy.

A randomized controlled trial of two chemotherapy regimens-paclitaxel liposome combined with platinum and paclitaxel combined with platinum in concurrent chemoradiotherapy for cervical carcinoma

Objective:The aim of the study was to compare the efficacy,side effect and influence on the survival rate of two chemotherapy regimens,paclitaxel liposome combined with platinum and paclitaxel combined with platinum,in concurrent chemoradiotherapy for cervical carcinoma.Methods:The 162 cases with primary cervical carcinoma diagnosed between January 2008 and November 2009 in Jiangxi Maternal and Child Health Hospital(China) were enrolled in this randomized controlled trial.Seventy-one cases were included in paclitaxel group and 91 in paclitaxel liposome group.And the chemotherapy doses were as follows:paclitaxel liposome and paclitaxel 135 mg/m2;cisplatin 80 mg/m2 or carboplatin AUC 4-6;then repeated every 21 days for two or three times.Radical radiotherapy was given to both groups at the same time.Efficacy was evaluated according to the tumor regression six months later and follow-up was done consistently.Results:The overall response rates of paclitaxel group and paclitaxel liposome group were 90.1% and 89 % respectively(P > 0.05).The one year cumulative survival was 91.4% for paclitaxel group and 89.2% for paclitaxel liposome group(P > 0.05).The incidence rates of adverse effects such as rash,gastrointestinal toxicity,bone marrow suppression and muscle/joint pain in paclitaxel liposome group were much lower than those in paclitaxel group(P < 0.05),while there was no difference regarding hair loss,hepatic function damage,peripheral neuritis and other aspects(P > 0.05).Conclusion:Paclitaxel liposome plus platinum is a safe and effective method for staging IIa-IV cervical carcinomas.While the long-term efficacy should be further observed.

Neoadjuvant chemotherapy plus intensity-modulated radiotherapy versus concurrent chemoradiotherapy plus adjuvant chemotherapy for the treatment of locoregionally advanced nasopharyngeal carcinoma:a retrospective controlled study

Background:In the era of intensity-modulated radiotherapy(IMRT),the role of neoadjuvant chemotherapy(NAC)for locoregionally advanced nasopharyngeal carcinoma(NPC)is under-evaluated.The aim of this study was to compare the efficacy of NAC plus IMRT and concurrent chemoradiotherapy(CCRT)plus adjuvant chemotherapy(AC)on locoregionally advanced NPC.Methods:Between January 2004 and December 2008,240 cases of locoregionally advanced NPC confirmed by pathologic assessment in Sun Yat-sen University Cancer Center were reviewed.Of the 240 patients,117 received NAC followed by IMRT,and 123 were treated with CCRT plus AC.The NAC+IMRT group received a regimen that included cisplatin and 5-fluorouracil(5-FU).The CCRT+AC group received cisplatin concurrently with radiotherapy,and subsequently received adjuvant cisplatin and 5-FU.The survival rates were assessed by Kaplan-Meier analysis,and the survival curves were compared using a log-rank test.Multivariate analysis was conducted using the Cox proportional hazard regression model.Results:The 5-year overall survival(OS),locoregional relapse-free survival(LRRFS),distant metastasis-free survival(DMFS),and disease-free survival(DFS)were 78.0,87.9,79.0,and 69.8%,respectively,for the NAC+IMRT group and78.7,84.8,76.2,and 65.6%,respectively,for the CCRT+AC group.There were no significant differences in survival between the two groups.In multivariate analysis,age(<50 years vs.>50 years)and overall stage(Ⅲvs.Ⅳ)were found to be independent predictors for OS and DFS;furthermore,the overall stage was a significant prognostic factor for DMFS.Compared with the CCRT+AC protocol,the NAC+IMRT protocol significantly reduced the occurrence rates of grade 3-4 nausea-vomiting(6.5 vs.1.5%,P=0.023)and leukopenia(9.7 vs.0.8%,P=0.006).Conclusions:The treatment outcomes of the NAC+IMRT and CCRT+AC groups were similar.Distant metastasis remained the predominant mode of treatment failure.

Efficacy of concurrent chemoradiotherapy plus adjuvant chemotherapy on advanced cervical cancer

Background and Objective: Concurrent chemoradiotherapy for cervical carcinoma develops rapidly and has become a common and standard therapy in recent years. Both the local control rate and survival rate of patients were increased and the risk of death fell by 30%-50%. This study aimed to explore the efficacy of concurrent chemoradiotherapy plus adjuvant chemotherapy on and the treatment compliance of the patients with advanced cervical squamous cell carcinoma. Methods: A total of 156 patients with stage IIa-IIIb cervical squamous cell carcinoma were randomly divided into the concurrent chemoradiotherapy group (experimental group) and radiotherapy group (control group). Intracavity and external beam radiation therapy were administered. At point A, 40-48 Gy were given by 10-12 fractions; at point B, 46-50 Gy were given by 23-25 fractions. In the same time, experimental group was treated by cisplatin (DDP, 40 mg) on day 1, repeated every week. Ten days after radiation therapy, TP regimen was administered as adjuvant chemotherapy. Results: For the experimental and control groups, the objective response rates were 88.61% and 75.32%, 1-year survival rates were 88.57% and 70.77%, 1-year local control rates were 81.43% and 64.62%, 3-year survival rates were 82.14% and 57.69%, and 3-year local control rates were 75.00% and 46.15%, with significant differences (P < 0.05). Quality of life of all patients were significantly improved after treatment (P< 0.05). Conclusion: Concurrent chemoradiotherapy plus adjuvant chemotherapy for advanced cervical cancer can improve short-term and long-term survival and local control rates of patients, improve the quality of life, and the toxicity can be tolerated.

Phase 1/2 study of concurrent chemoradiotherapy with weekly irinotecan hydrochloride for advanced/recurrence uterine cancer:A multi-institutional study of Kansai Clinical Oncology Group

Objective:Concurrent chemoradiotherapy using cisplatin was thought to be standard treatment for squamous cell carcinoma of cervix,but it had not been effective for adenocarcinoma.Concurrent chemoradiotherapy using irinotecan hydrochloride(CPT-11)had been effective for colorectal cancer,thus,we chose CPT-11 as a candidate for gynecologic adenocarcinoma.To evaluate the maximum tolerated dose(MTD)of weekly CPT-11 with external pelvic radiotherapy,a phase 1/2 study was conducted according to modified Fibonacci method.Methods:Eligible patients were advanced uterine cancer with measurable diseases[performance score(PS):0-2].Study period was from August 1 st,2002 to December 31 st,2008.The starting dose level(DL)of CPT-11 was 30 mg/m2(DL1)given weekly for 4 weeks.Subsequently,dose escalation was scheduled in 10 mg/m2 increments to 60 mg/m^2(DL4).The fixed radiotherapy consisted of whole pelvic 1.8 Gy/d,once a day in weekday for five weeks and it amounted to 45 Gy(25 fractions)in total.Results:Seventeen patients were enrolled.As for toxicities,one(1/17:5.9%)grade(G)4 neutropenia lasting 7 days had been seen in DL4.G2 diarrhea was identified in 35.3%(6/17)of the patients,and 11.8%(2/17)G3 diarrhea was observed in DL3 and DL4.Thus,the MTD of CPT-11 was defined as dose of 60 mg/m^2.The recommended dose was decided as 50 mg/m^2.The response rate was 88.2%[9 complete response(CR),3 partial response(PR),3 stable disease(SD),2 not evaluable(NE)].Disease control rate at 1 month after treatment completion was 100%but distant metastases were found in 24%(4/17)in longer outcome.Conclusions:MTD was 60 mg/m^2 and recommended dose was set as 50 mg/m2.This concurrent chemoradiation using weekly CPT-11 was feasible at 50 mg/m^2,and it might be effective even in adenocarcinoma of the uterus.

Efficacy of concurrent chemoradiotherapy with thalidomide and S-1 for esophageal carcinoma and its influence on serum tumor markers

BACKGROUND Although the current conventional treatment strategies for esophageal carcinoma(EC)have been proven effective,they are often accompanied by serious adverse events.Therefore,it is still necessary to continue to explore new therapeutic strategies for EC to improve the clinical outcome of patients.AIM To elucidate the clinical efficacy of concurrent chemoradiotherapy(CCRT)with thalidomide(THAL)and S-1(tegafur,gimeracil,and oteracil potassium capsules)in the treatment of EC as well as its influence on serum tumor markers(STMs).METHODS First,62 patients with EC treated at the Zibo 148 Hospital between November 2019 and November 2022 were selected and grouped according to the received treatment.Among these,30 patients undergoing CCRT with cis-platinum and 5-fluorouracil were assigned to the control group(Con),and 32 patients receiving CCRT with THAL and S-1 were assigned to the research group(Res).Second,inter-group comparisons were carried out with respect to curative efficacy,incidence of drug toxicities,STMs[carbohydrate antigen 125(CA125)and macrophage inflammatory protein-3α(MIP-3α)],angiogenesis-related indicators[vascular endothelial growth factor(VEGF);VEGF receptor-1(VEGFR-1);basic fibroblast growth factor(bFGF);angiogenin-2(Ang-2)],and quality of life(QoL)[QoL core 30(QLQ-C30)]after one month of treatment.RESULTS The analysis showed no statistical difference in the overall response rate and disease control rate between the two patient cohorts;however,the incidences of grade I–II myelosuppression and gastrointestinal reactions were significantly lower in the Res than in the Con.Besides,the post-treatment CA125,MIP-3α,VEGF,VEGFR-1,bFGF,and Ang-2 Levels in the Res were markedly lower compared with the pre-treatment levels and the corresponding post-treatment levels in the Con.Furthermore,more evident improvements in QLQ-C30 scores from the dimensions of physical,role,emotional,and social functions were determined in the Res.CONCLUSION The above results demonstrate the effectiveness of THAL+S-1 CCRT for EC,which contributes to mild side effects and significant reduction of CA125,MIP-3α,VEGF,VEGFR-1,bFGF,and Ang-2 Levels,thus inhibiting tumors from malignant progression and enhancing patients’QoL.

Clinical study on concurrent chemoradiotherapy combined with Kanglaite injection in the treatment of regionally advanced unresectable non-small cell lung cancer

Objective： To evaluate the clinical effects and toxicity of concurrent chemoradiotherapy combined with Kanglaite injection in the treatment of regionally advanced unresectable non-small cell lung cancer. Methods： 48 patients with regionally advanced unresectable non-small cell lung cancer were randomized to two groups, 25 patients in the combination group （concurrent chemoradiotherapy ＋ Kanglaite） and 23 patients in the control group （concurrent chemoradiotherapy）. The combination group received chemotherapy of vinorelbine （NVB） plus cisplatin （DDP） regimen, radiotherapy was given with conventional fraction in 2 Gy per fraction and five fractions per week concurrently. The total tumor doses were 56-60 Gy. Combined with Kanglaite injection 200 mud for twenty-one days for two courses in the combination group, the control group was chemoradiotherapy only. Effects and toxicities were evaluated according to the criteria of WHO. Results： The CR rates in the combination group and control group were 24.0% （6/25） and 13.0% （3/23）, respectively （P 〉 0.05）. Response （CR ＋ PR） rates of combination group were 76.0 % （19/25） and 69.6% （16/23） in control group, P 〉 0.05. The incidence rates of grades 3-4 leukocytopenia, grades 3-4 digestive system （nausea and vomiting） and grades 3-4 esophagitis in the combination group and control group were 40.0% （10/25）, 8.0% （2/25）, 16.0% （4/25） and 69.6% （16/23）, 34.8% （8/23）, 43.5% （10/23）, respectively （P 〈 0.05）. KPS and body weight score significantly increased in combination group after the combined treatment, P 〈 0.05. Conclusion： Concurrent chemoradiotherapy combined with Kanglaite injection can relieve side effects of chemoradiotherapy in the treatment of regionally advanced unresectable non-small cell lung cancer, and improve quality of life. Kanglaite injection may increase effective rate of regionally advanced unresectable non-small cell lung cancer combined with concurrent chemoradiotherapy.

Objective:To investigate the efficacy of the Shengxuebao Mixture in treating anemia after concurrent chemoradiotherapy for cervical cancer.Methods:The patients who met the criteria were randomly divided into the study group(n=30)and the control group(n=30).The study group was treated with Shengxuebao Mixture(15 ml once,three times a day)for 30 days,and the control group was treated with ferrous succinate tablets(0.1 g,twice a day),folic acid tablets(5 mg,three times a day),and vitamin B12 tablets(25μg,once a day)for 30 days.Observed the hemoglobin level,erythropoietin level,TCM syndrome score,karnofsky performance status score before and after treatment in the two groups,compared the relevant data and clinical efficacy between the two groups and observed the adverse drug reactions at the same time.Results:The age,pathological type,stage,baseline hemoglobin level,erythropoietin level,TCM syndrome score,and karnofsky performance status score were comparable between the two groups(P>0.05).The hemoglobin level of the two groups after treatment was higher than before treatment(P<0.05).After treatment,the hemoglobin level in the study group was significantly higher than that in the control group(P<0.05),and the number of effective cases in the study group was more than that in the control group,and the effective rate in the study group was higher than that in the control group(P<0.05).The erythropoietin level of the two groups after treatment was lower than before treatment(P<0.05).After treatment,the erythropoietin level in the study group was significantly lower than that in the control group(P<0.05).The TCM syndrome score of the study group decreased significantly after treatment(P<0.05),but there was no significant change in the control group(P>0.05).After treatment,the TCM syndrome score of the study group was significantly lower than that of the control group(P<0.05),and the number of effective cases in the study group was more than that in the control group,and the effective rate in the study group was higher than that in the control group(P<0.05).There was no significant change in the karnofsky performance status score of the study group after treatment(P>0.05),but the karnofsky performance status score of the control group decreased significantly(P<0.05).After treatment,the karnofsky performance status score of the study group was higher than that of the control group(P<0.05),and the number of effective cases in the study group was more than that of the control group,and the effective rate was higher than that of the control group(P<0.05).And there were no obvious adverse reactions in this study.Conclusion:To some extent,this study showed that the Shengxuebao Mixture has a definite effect in treating anemia after concurrent chemoradiotherapy for cervical cancer,can promote the use of erythropoietin,improve TCM syndromes and stabilize the quality of life of patients.

Analysis of preoperative concurrent chemoradiotherapy for superior sulcus lung tumor

Objective： To compare the clinical effect and toxicities of preoperative concurrent chemoradiotherapy （CT/RT） with radiotherapy （RT） alone in patients with superior sulcus lung tumor. Methods： Fifty-six patients with superior sulcus lung tumor were divided randomly into two groups： twenty-six patients received concurrent chemoradiotherapy, the other thirty patients received only radiotherapy. For both groups, the same radiation technic was given with the convention fraction. The total dose was 45 Gy/25 Fr/5 Wk. For the CT/RT group, the patients were also given with concurrent chemotherapy （navelbine 15-18 mg/m^2 on the 1st and 8th day, cisplatin 60 mg/m^2 on the 1st day）. Results： The rate of complete resection in the CT/RT group was significantly higher than that in the RT group （92.3% vs 80%, P 〈 0.05）. The complete pathological response rate and 2-year survival rate in the CT/RT group were significantly higher than those in the RT group （P 〈 0.01, P 〈 0.01）. The incidences of grades Ill-IV radiation esophagitis and leukopenia in the CT/RT group were significantly higher than those in the RT group （23.1% and 23.1% vs 6.7% and 0, P 〈 0.01, P 〈 0.01）. Conclusion： Preoperative concurrent chemoradiotherapy has the potential of improving the survival rate of superior sulcus lung tumors. Though this treatment regimen also increases the acute toxic effect, all patients can tolerate it. It is expected to be a new ＂standard treatment＂ for this malignant tumor.

A Case of Bilateral Secondary Pneumothorax Shortly after the Completion of Concurrent Chemoradiotherapy for Tongue Cancer

Metastatic lung tumours rarely lead to development of pneumothorax, and no case of bilateral secondary pneumothorax due to lung metastases arising from tongue cancer has been reported. Here, we report a case of a patient with tongue cancer with lung metastases complicated by bilateral secondary pneumothorax soon after the completion of concurrent chemoradiotherapy. A 39-year-old man with cervical lymph node metastases originating from pT2N0M0 tongue cancer underwent neck dissection and postoperative concurrent chemoradiotherapy. Shortly after the completion of chemoradiotherapy, he developed bilateral secondary pneumothorax. Subsequently, he underwent partial lung resection for the pulmonary fistulae for diagnostic and therapeutic purposes;nodular lesions found in both the lungs. The diagnosis of secondary pneumothorax was based on histopathological findings. Although all pulmonary fistulae disappeared after partial lung resection, he died of the primary disease despite our best efforts to control the metastatic pulmonary lesions.

Effects of concurrent chemoradiotherapy on serum tumor markers, MMP-9, VEGF and inflammatory factors in patients with endometrial carcinoma after operation

Objective:To investigate effects of concurrent chemoradiotherapy on serum tumor markers, vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) and inflammatory factors in patients with endometrial carcinoma after operation.Methods: A total of 86 patients with endometrial carcinoma treated by surgery were selected as objects of study, according to random data table they were divided into control group (n=42) and observation group (n=44), patients of two groups were all underwent hysterectomy and bilateral adnexectomy treatment, on this basis, the control group was given radiotherapy treatment, observation group patients received concurrent chemotherapy treatment, the levels of serum tumor markers, VEGF, MMP-9 and inflammatory factor of the two groups before and after treatment were compared.Results: Before treatment, there was no significant difference in CA-125, HE4, VEGF, MMP-9, TNF-α, CRP and IL-6 levels between the observation group and the control group;After treatment, the levels of CA-125, HE4, VEGF, MMP-9, TNF-α, CRP and IL-6 in the two groups were significantly lower than those in the group before treatment, and the difference was statistically significant;After treatment, the levels of CA-125, HE4, VEGF, MMP-9, TNF-α, CRP and IL-6 in the observation group were significantly lower than those in the control group, the difference was statistically significant.Conclusion:The concurrent radiotherapy and chemotherapy can effectively reduce the levels of serum tumor markers, VEGF and MMP-9, and effectively decrease the inflammatory stress response in patients with endometrial carcinoma after operation, with critical clinical value.

Phase I Study to Determine MTD of Docetaxel and Cisplatin with Concurrent Radiation Therapy for Stage Ⅲ Non-Small Cell Lung Cancer

Objective： To evaluate the maximum tolerated dose （MTD） of docetaxel （DCT） and cisplatin （DDP） concurrently with three dimensional （3D） conformal radiotherapy or IMRT for patients with locally advanced non-small cell lung cancer （stage IIIa and IIIb） after 2–4 cycles of induction chemotherapy. Methods： Fourteen patients with histological/cytological proven stage III non–small-cell lung cancer were eligible. 3D or IMRT radiotherapy （60-70Gy in 30-35 fractions, 6-7weeks, 2 Gy/fraction） was delivered concurrently with cisplatin and docetaxel, 2 cycles during concurrent chemoradiotherapy （CCRT）. The level I dosage was composed of 56 mg/m2 DCT, on day 1 and 28mg/m2 DDP, on day 1 and day 2. The level II was composed of 60 mg/m2 DCT, on day 1 and 30 mg/ m2 DDP, on day 1 and day 2. The level III was composed of 64 mg/m2 DCT, on day 1 and 32 mg/ m2 DDP, on day 1 and day 2. Results： Fourteen patients were allocated and finished concurrent chemoradiotherapy. The dose-limiting neutropenia was at the dose Level III （64 mg/m2） and occurred in 2 of 5 patients. No dose limiting non-hematologic or hematologic toxicity occurred in the other patients. Conclusions： Patients with locally advanced non-small cell lung cancer may tolerate 60mg/m2 docetaxel and 60mg/m2 cisplatin for 2 cycles during concurrent radiotherapy after 2-3 cycles of induction chemotherapy.

Initial outcome of induction chemotherapy followed by radiotherapy and concurrent weekly paclitaxel for stage Ⅲ non-small cell lung cancer

Objective： The aim of our study was to evaluate the toxicity and efficacy of induction chemotherapy （ICT） followed by three-dimensional conformal radiotherapy （3D CRT） and concurrent weekly paclitaxel on unresectable non-small cell lung cancer （NSCLC）. Methods： Stage III NSCLC patients with favorable conditions were treated with 2 to 4 cycles of carboplatin （AUC = 5-6, dl） combined with paclitaxel （175 mg/m〈 dl）, then followed by weekly paclitaxel （40 mg/m2） and concurrent 3D CRT within 3-4 weeks. The prescription dose was given as high as possible under the condition that V20 〈 31% and spinal cord dose 〈 50 Gy. Results： Thirty-one patients were enrolled. ICT was well tolerated. During the concurrent chemoradiotherapy, the treatment of 3 patients was ended ahead of the schedule because of severe pulmonary and heart toxicities; the treatment of 2 patients was delayed for 7 and 12 days because of fatigue. Myelosuppression was mild （16/31）： all were grade 1-2 except 1 was grade 3. Lymphocytopenia was more obvious （29/31, grade 3 in 21）. Three patients developed grade 3 radiation-induced esophagitis, and 2 developed grades 3-4 radiation-induced pneumonitis. Two developed grade 3 esophageal stricture. No grades 3-4 pulmonary fibrosis was observed. The overall response rate was 74.1%. The 1-, 2-, 3-year overall survival rates were 74.2%, 41.9%, and 34.6%, respectively, with the median survival time of 18.5 months. The 1-, 2-, 3-year local progression-freely survival rates were 64.5%, 32.3%, and 20.5%, respectively, with the median local progression-freely survival time of 14.3 months. Conclusion： The program of ICT followed by weekly paclitaxel and 3D CRT is accomplished in most of the favorable stage III NSCLC patients. The toxicity is tolerable, and the response rate is inspiriting.

Clinical analysis of PF plus concurrent radiotherapy in locally advanced nasopharyngeal carcinoma

Objective： The prognosis of patients with nasopharyngeal carcinoma （NPC） depends on the stage of the disease at diagnosis. Unfortunately, at diagnosis, most of patients have locally advanced, non-metastatic stage III or IVa disease. The study was to evaluate the efficacy and toxicities of cisplatin plus 5-fluorouracil combined with concurrent radiotherapy for locally advanced nasopharyngeal carcinoma. Methods： Sixty-six patients with locally advanced nasopharyngeal carcinoma received chemotherapy of cisplatin plus 5-fluorouracil jointing concurrent radiotherapy; concurrent radiotherapy started on day 1 in the first cycle of chemotherapy of PF, 5-fluorouraci1500 mg/m^2 intravenous infusion on days 1-5, cisplatin 80 mg/m2 intravenous infusion on days 1-3, 21 days for a cycle, a total of three cycles; nasopharyngeal lesions and positive lymph node were given a total amount of 70 Gy, prophylactic neck radiation were given the amount of 50 Gy, radiotherapy five times a week, Gy/f. Results： All patients who can be evaluated, the response rate （RR） was 100%; 1-, 3- and 5-year overall survival （OS） were 100%, 86.4%, 21.2%, respectively; 3-year, 5-year disease-free survival （DFS） were 72.7% and 18.2%, respective- ly; the average survival time and median survival time were 49.0 months and 48.5 months, respectively; the average survival time and median survival time of DFS were 46.1 months and 46.5 months, respectively. Conclusion： For patients with locally advanced nasopharyngeal carcinoma, who accepted RT combining concurrent chemotherapy of cisplatin plus 5-fluorouracil, clinical efficacy is satisfaction and toxicities could be tolerated.
