BACKGROUND Testicular torsion is the most common acute scrotum worldwide and mainly occurs in children and adolescents.Studies have demonstrated that the duration of symptoms and torsion grade lead to different outcomes in children diagnosed with testicular torsion.AIM To predict the possibility of testicular salvage(TS)in patients with testicular torsion in a tertiary center.METHODS We reviewed the charts of 75 pediatric patients with acute testicular torsion during a 12-year period from November 2011 to July 2023 at the Suzhou Hospital of Anhui Medical University.Univariate and multivariate logistic regression analyses were used to determine independent predictors of testicular torsion.The data included clinical findings,physical examinations,laboratory data,color Doppler ultrasound findings,operating results,age,presenting institution status,and follow-up results.RESULTS Our study included 75 patients.TS was possible in 57.3%of all patients;testicular torsion occurred mostly in winter,and teenagers aged 11-15 years old accounted for 60%.Univariate logistic regression analyses revealed that younger age(P=0.09),body mass index(P=0.004),torsion angle(P=0.013),red blood cell count(P=0.03),neutrophil-to-lymphocyte ratio(P=0.009),and initial presenting institution(P<0.001)were associated with orchiectomy.In multivariate analysis,only the initial presenting institution predicted TS(P<0.05).CONCLUSION The initial presenting institution has a predictive value for predicting TS in patients with testicular torsion.Children with scrotal pain should be admitted to a tertiary hospital as soon as possible. 展开更多

BACKGROUND For recurrent achalasia after initial peroral endoscopic myotomy(POEM)failure,repeat POEM(Re-POEM)has been reported as a treatment option.However,severe esophageal interlayer adhesions caused by previous procedures impede the successful establishment of a submucosal tunnel and lead to aborted Re-POEM procedures.Our team previously described POEM with simultaneous submucosal and muscle dissection(POEM-SSMD)as a feasible solution for achalasia with severe interlayer adhesions.AIM To investigate the effectiveness and safety of Re-POEM with simultaneous submucosal and muscle dissection(Re-POEM-SSMD).METHODS A total of 1049 patients with achalasia who underwent successful endoscopic myotomy at the Digestive Endoscopic Center of Chinese PLA General Hospital from December 2014 to May 2022 were reviewed.Patients with recurrent achalasia who experienced initial POEM clinical failure were retrospectively included in this study.The primary endpoint was retreatment clinical success,defined as an Eckardt score≤3 during the postretreatment follow-up and no need for additional treatment.Procedure-related adverse events,changes in manometric lower esophageal sphincter(LES)pressure and reflux complications,as well as procedure-related parameters,were recorded.RESULTS Sixteen patients underwent Re-POEM(9 patients)or Re-POEM-SSMD(7 patients)successfully at a median of 45.5 mo(range,4-95 mo)after initial POEM.During a median followup period of 31 mo(range,7-96 mo),clinical success(Eckardt score≤3)was achieved in 8(88.9%)and 6(85.7%)patients after Re-POEM and Re-POEM-SSMD,respectively(P=0.849).The median Eckardt score dropped from 4(range,3-8)at preretreatment to 1(range,0-5)at postretreatment in the Re-POEM group(P=0.025)and from 5(range,2-8)to 2(range,0-4)in the Re-POEM-SSMD group(P<0.001).The mean manometric LES pressure decreased from 23.78±9.04 mmHg to 11.45±5.37 mmHg after Re-POEM(P<0.001)and from 26.80±7.48 mmHg to 11.05±4.38 mmHg after Re-POEM-SSMD(P<0.001).No serious adverse events were recorded in both groups.CONCLUSION In conclusion,Re-POEM-SSMD appears to be a safe and effective salvage therapy for recurrent achalasia with severe interlayer adhesions. 展开更多

Hepatocellular carcinoma(HCC)is the second most common cause of cancerrelated death worldwide.Despite the advent of screening efforts and algorithms to stratify patients into appropriate treatment strategies,recurrence rates remain high.In contrast to first-line treatment for HCC,which relies on several factors,including clinical staging,tumor burden,and liver function,there is no consensus or general treatment recommendations for recurrent HCC(R-HCC).Locoregional therapies include a spectrum of minimally invasive liver-directed treatments which can be used as either curative or neoadjuvant therapy for HCC.Herein,we provide a comprehensive review of recent evidence using salvage loco-regional therapies for R-HCC after failed curative-intent. 展开更多

BACKGROUND Rotationplasty is often performed for malignant tumors,but type BIIIb rotationplasty is rarely reported,and there needs to be more evidence of the procedure and treatment.The purpose of this case study was to report a new direction in the use of type BIIIb rotationplasty in treating patients with limb salvage and longterm non-healing infections.CASE SUMMARY Case 1:A 47-year-old man underwent radiotherapy for hemangioendothelioma in his left thigh,resulting in a femoral fracture.Despite the use of plates,intramedullary nailing,and external fixators,the femoral bone failed to unite due to infectious nonunion.Multiple operations were unable to control the infection,leaving the patient immobile.We performed a modified tibia-pelvic-constrained hip rotationplasty,utilizing a constrained prosthetic hip between the tibia and pelvis following a femur resection.Two years post-surgery,the patient was able to walk with the prosthetic device without any signs of recurring infection.The corresponding functional scores were 72 points for the Musculoskeletal Tumor Society(MSTS),53 for the Functional Mobility Assessment(FMA),93 for the Toronto Extremity Salvage Score(TESS),and 56 for the MOS 36-item short form health survey(SF-36).Case 2:A 59-year-old woman presented with liposarcoma in her left thigh.Magnetic resonance imaging revealed tumors in the medial,anterior,and posterior femur muscles,encircling the femoral vessels and nerves.Fortunately,there were no symptoms of sciatic dysfunction,and the tumor had not invaded the sciatic nucleus.After one year of follow-up,the patient expressed satisfaction with limb preservation post-type BIIIb rotationplasty.The corresponding functional scores were 63 points for the MSTS,47 for the FMA,88 for the TESS,and 52 for the SF-36.CONCLUSION Our study suggests that type BIIIb rotationplasty may be an alternative to amputation in patients with incurable infections.For malignant tumors of the lower extremities without invasion of the sciatic nerve,type BIIIb rotationplasty remains an excellent alternative to amputation.This surgical method may prevent amputation,improve functional outcomes,and facilitate biological reconstruction. 展开更多

Even experienced endoscopists have 90% success in achieving deep biliary cannulation with standard methods. Biliary cannulation may become difficult in 10%-15% of patients with biliary obstruction and pre- cut (access) sphincterotomy is frequently chosen as a rescue treatment in these cases. Generally, precut sphincterotomy ensures a rate of 90%-100% success- ful deep biliary cannulation. The precut technique has been performed as either a fistulotomy with a needle knife sphincterotome or as a transpapillary septotomy with a standard sphincterotome. Both methods have similar efficacy and complication rates when adminis- tered to the proper patient. Although precut sphincter- otomy ensures over 90% success of biliary cannula- tion, it has been characterized as an independent risk factor for pancreatitis. The complications of the precut technique are not limited to pancreatitis. Two more important ones, bleeding and perforation, are also re- ported in some publications as being observed more commonly than during standard sphincterotomy. It is also reported that precut sphincterotomy increases morbidity when performed in patients without dilata- tion of their biliary tract. Nevertheless, precut sphinc- terotomy is a good alternative as a rescue method in the setting of a failed standard cannulation method. This paper discusses the technical details, timing, ef- ficacy and potential complications of precut sphincter- otomy. 展开更多

AIM To review the conversion therapy for initially unre-sectable hepatocellular carcinoma(HCC) patients and the suitable timing for subsequent salvage surgery. METHODS A Pub Med search was undertaken from 1987 to 2017 to identify articles using the keywords including "unresectable" "hepatocellular carcinoma", "hepate-ctomy", "conversion therapy", "resection", "salvage surgery" and "downstaging". Additional studies were investigated through a manual search of the references from the articles. The exclusion criteria were duplicates, case reports, case series, videos, contents unrelated to the topic, comments, and editorial essays. The main and widely used conversion therapies and the suitable timing for subsequent salvage surgery were discussed in detail. Two members of our group independently performed the literature search and data extraction. RESULTS Liver volume measurements [future liver remnant(FLR)/total liver volume or residual liver volume/bodyweight ratio] and function tests(scoring systems and liver stiffness) were often performed in order to justify whether patients were suitable candidates for surgery. Successful conversion therapy was usually defined as downstaging the tumor, increasing FLR and providing subsequent salvage surgery, without increasing com-plications, morbidity or mortality. The requirementsfor performing salvage surgery after transcatheter arterial chemoembolization were the achievement of a partial remission in radiology, the disappearance of the portal vein thrombosis, and the lack of extrahepatic metastasis. Patients with a standardized FLR(sF LR) > 20% were good candidates for surgery after portal vein embolization, while other predictive parameters like growth rate, kinetic growth rate were treated as an effective supplementary. There was probably not enough evidence to provide a standard operation time after associating liver partition and portal vein ligation for staged hepatectomy or yttrium-90 microsphere radioembolization. The indications of any combinations of conversion therapies and the subsequent salvage surgery time still need to be carefully and comprehen-sively evaluated. CONCLUSION Conversion therapy is recommended for the treatment of initially unresectable HCC, and the suitable subse-quent salvage surgery time should be reappraised and is closely related to its previous therapeutic effect. 展开更多

About 25000 LTs are performed annually in the world. The potential for intraoperative bleeding is quite variable. However, massive bleeding is common and requires blood transfusion. Allogeneic blood transfusion has an immunosuppressive effect and an impact on recipient survival, in addition to the risk of transmission of viral infections and transfusion errors, among others.Techniques to prevent excessive bleeding or to use autologous blood have been proposed to minimize the negative effects of allogeneic blood transfusion.Intraoperative reinfusion of autologous blood is possible through previous selfdonation or blood collected during the operation. However, LT does not normally allow autologous transfusion by prior self-donation. Hence, using autologous blood collected intraoperatively is the most feasible option. The use of intraoperative blood salvage autotransfusion(IBSA) minimizes the perioperative use of allogeneic blood, preventing negative transfusion effects without negatively impacting other clinical outcomes. The use of IBSA in patients with cancer is still a matter of debate due to the theoretical risk of reinfusion of tumor cells. However, studies have demonstrated the safety of IBSA in several surgical procedures, including LT for hepatocellular carcinoma. Considering the literature available to date, we can state that IBSA should be routinely used in LT, both in patients with cancer and in patients with benign diseases. 展开更多

The boat is wooden, loaded with cultural relics. It has been immersed at the bottom of the South China Sea for more than 800 years. In order to protect the structure of the boat and the cultural relics inside to the largest extent, an open caisson is used to hold the sunken beat and the silts around before they are raised from the seabed all together as a whole. In the paper, first, the seakeeping model test of the system of the salvage barge and the open caisson is done to determine some important wave response parameters. And then a further experimental study of the ap- plication of the vertical hoisting jack and wave motion compensation scheme to the salvage of the sunken boat is carried out. In the model tests, the techniques of the integrative mechanic-electronic-hydraulic control, wave motion forecast and wave motion compensation are used to minimize the heave motion of the open caisson. The results of the model tests show that the heave motion of the open caisson can be reduced effectively by the use of the present method. 展开更多

Background: After deinitive chemoradiotherapy for non-metastatic nasopharyngeal carcinoma(NPC), more than 10% of patients will experience a local recurrence. Salvage treatments present signiicant challenges for locally recurrent NPC. Surgery, stereotactic ablative body radiotherapy, and brachytherapy have been used to treat locally recurrent NPC. However, only patients with small-volume tumors can beneit from these treatments. Re-irradiation with X-ray—based intensity-modulated radiotherapy(IMXT) has been more widely used for salvage treatment of locally recurrent NPC with a large tumor burden, but over-irradiation to the surrounding normal tissues has been shown to cause frequent and severe toxicities. Furthermore, locally recurrent NPC represents a clinical entity that is more radioresistant than its primary counterpart. Due to the inherent physical advantages of heavy-particle therapy, precise dose delivery to the target volume(s), without exposing the surrounding organs at risk to extra doses, is highly feasible with carbon-ion radiotherapy(CIRT). In addition, CIRT is a high linear energy transfer(LET) radiation and provides an increased relative biological efectiveness compared with photon and proton radiotherapy. Our prior work showed that CIRT alone to 57.5 Gy E(gray equivalent), at 2.5 Gy E per daily fraction, was well tolerated in patients who were previously treated for NPC with a deinitive dose of IMXT. The short-term response rates at 3–6 months were also acceptable. However, no patients were treated with concurrent chemotherapy. Whether the addition of concurrent chemotherapy to CIRT can beneit locally recurrent NPC patients over CIRT alone has never been addressed. It is possible that the beneits of high-LET CIRT may make radiosensitizing chemotherapy unnecessary. We therefore implemented a phase I/II clinical trial to address these questions and present our methodology and results.Methods and design: The maximal tolerated dose(MTD) of re-treatment using raster-scanning CIRT plus concurrent cisplatin will be determined in the phase I, dose-escalating stage of this study. CIRT dose escalation from 52.5 to 65 Gy E(2.5 Gy E × 21–26 fractions) will be delivered, with the primary endpoints being acute and subacute toxicities. Eicacy in terms of overall survival(OS) and local progression-free survival of patients after concurrent chemotherapy plus CIRT at the determined MTD will then be studied in the phase II stage of the trial. We hypothesize that CIRT plus chemotherapy can improve the 2-year OS rate from the historical 50% to at least 70%.Conclusions: Re-treatment of locally recurrent NPC using photon radiation techniques, including IMXT, provides moderate eicacy but causes potentially severe toxicities. Improved outcomes in terms of eicacy and toxicity proile are expected with CIRT plus chemotherapy. However, the MTD of CIRT used concurrently with cisplatin-based chemotherapy for locally recurrent NPC remains to be determined. In addition, whether the addition of chemotherapy to CIRT is needed remains unknown. These questions will be evaluated in the dose-escalating phase I and randomized phase II trials. 展开更多

Intraoperative blood salvage autotransfusion (IBSA) is used in various surgical procedures. However, because of the risk of reinfusion of salvaged blood contaminated by tumor cells, the use of IBSA in hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT) is controversial. The critical points include whether tumor cells can be cleared by IBSA, whether IBSA increases the risk of recurrence or metastasis, and what are the indications for IBSA. Moreover, is it warranted to take the risk of tumor dissemination by using IBSA to avoid allogeneic blood transfusion? Do the remaining tumor cells after additional filtration by leukocyte depletion filters still possess potential tumorigenicity? Does IBSA always work well? We have reviewed the literature and tried to address these questions. The available data indicate that IBSA is safe in LT for HCC, but randomized, controlled and prospective trials are urgently required to clarify the uncertainty. 展开更多

Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. 展开更多

The overall incidence of osteochondral defect in the general population is estimated to be 15 to 30 per100000 people.These lesions can become symptomatic causing pain,swelling and decreased function of the knee,and may eventually progress to osteoarthritis.In the young and active population,partial or total knee arthroplasty(TKA)is rarely the treatment of choice due to risk of early failure.Osteochondral allograft transplantation has been demonstrated to be a safe and effective treatment of large osteochondral and chondral defects of the knee in appropriately selected patients.The treatment reduces pain,improves function and is a viable limb salvage procedure for patients,especially young and active patients for whom TKA is not recommended.Either large dowels generated with commercially available equipment or free hand shell allografts can be implanted in more posterior lesions.Current recommendations for fresh allografts stored at4C advise implantation within 21-28 d of procurement for optimum chondrocyte viability,following screening and testing protocols.Higher rates of successful allograft transplantation are observed in younger patients,unipolar lesions,normal or corrected malalignment,and defects that are treated within 12 mo of symptom onset.Patients with bipolar lesions,uncorrectable malalignment,advanced osteoarthritis,and those over40 tend to have less favourable outcomes. 展开更多

External beam radiotherapy(EBRT) is one of the principal curative treatments for patients with prostate cancer(PCa). Risk group classification is based on prostate-specific antigen(PSA) level, Gleason score, and T-stage. After risk group determination, the treatment volume and dose are defined and androgen deprivation therapy is prescribed, if appropriate. Traditionally, imaging has played only a minor role in T-staging due to the low diagnostic accuracy of conventional imaging strategies such as transrectal ultrasound, computed tomography, and morphologic magnetic resonance imaging(MRI). As a result, a notable percentage of tumours are understaged, leading to inappropriate and imprecise EBRT. The development of multiparametric MRI(mp MRI), an imaging technique that combines morphologic studies with functional diffusion-weighted sequences and dynamic contrastenhanced imaging, has revolutionized the diagnosis and management of PCa. As a result, mpM RI is now used in staging PCa prior to EBRT, with possible implications for both risk group classification and treatment decisionmaking for EBRT. mpM RI is also being used in salvageradiotherapy(SRT), the treatment of choice for patients who develop biochemical recurrence after radical prostatectomy. In the clinical context of biochemical relapse, it is essential to accurately determine the site of recurrence-pelvic(local, nodal, or bone) or distant-in order to select the optimal therapeutic management approach. Studies have demonstrated the value of mpM RI in detecting local recurrences-even in patients with low PSA levels(0.3-0.5 ng/m L)-and in diagnosing bone and nodal metastasis. The main objective of this review is to update the role of mpM RI prior to radical EBRT or SRT. We also consider future directions for the use and development of MRI in the field of radiation oncology. 展开更多

Korean Sewol is successfully lifted up with the strand jack system based on twin barges. During the salvage operation, two barges and Sewol encounter offshore environmental conditions of wave, current and wind. It is inevitable that the relative motions among the three bodies are coupled with the sling tensions, which may cause big dynamic loads for the lifting system. During the project engineering phase and the site operation, it is necessary to build up a simulation model that can precisely generate the coupled responses in order to define a suitable weather window and monitor risks for the salvage operation. A special method for calculating multibody coupled responses is introduced into Sewol salvage project. Each body’s hydrodynamic force and moment in multibody configuration is calculated in the way that one body is treated as freely moving in space, while other bodies are set as fixed globally.The hydrodynamic force and moment are then applied into a numerical simulation model with some calibration coefficients being inserted. These coefficients are calibrated with the model test results. The simulation model built up this way can predict coupled responses with the similar accuracy as the model test and full scale measurement,and particularly generate multibody shielding effects. Site measured responses and the responses only resulted from from the simulation keep project management simultaneously to judge risks of each salvage stage, which are important for success of Sewol salvage. 展开更多

The increase in forest-wildfire events around the world has revived the old debate regarding the practice of salvage logging and its effectiveness in comparison to the unlogged, natural regeneration of burned forests. Since the logging of burned trees may have undesirable outcomes in soil systems, such as soil compaction and nutrient losses, these changes could further cause disturbances to soil microbial-community activity. The aim of this study was to examine chemical and biological changes in soil under two post-fire practices: salvage logging and unlogged, natural regeneration of burned areas, in the recently burned Byria Forest in Israel. Results indicated that salvage logging had a short- lived effect on soil chemical and biological properties that was confined mostly to the first year after logging. Soil moisture was greatly affected by salvage logging, and drier conditions were found in the logged compared to the unlogged burned areas. Moreover, logging had a negative effect on microbial biomass, with reduced biomass in the logged compared to unlogged areas, which was more evident during the first year after fire. These findings support the recommendations in the literature to postpone post-fire practices such as logging or, in turn, to combine the two practices in order to create a mosaic of burned-logged and burned-naturally regenerated areas. 展开更多

Background and Objective: Osteosarcoma is a rare bone cancer with approximately 30% - 35% of patients who will relapse either systemically or locally, with the lung being the commonest site of relapse. The objective of this trial was to evaluate the efficacy of cyclophosphamide and etoposide, in treatment of metastatic osteosarcoma patients progressed after one or more chemotherapy lines, with the progression free survival and treatment response as the primary endpoints, while the secondary endpoints were overall survival and treatment toxicity. Patients and Methods: Twenty seven metastatic osteosarcoma patients were enrolled into this trial and received cyclophosphamide and etoposide chemotherapy. Cyclophosphamide was given at a dose of 500 mg/m2 per day, I.V for 5 days and etoposide (100 mg/m2 per day I.V for 5 days). Response was assessed after 3 cycles according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Chemotherapy Toxicity was graded according to the Common Terminology Criteria for Adverse Events (CTCAE). Results: The median overall survival time and progression-free survival were 12 months and 8 months, respectively. Four patients (14.8%) achieved partial response;14 patients (51.9%) had stationary disease (SD);and 9 (33.3%) expressed tumor progression. Hematologic toxicity was the main toxicity. None of the patients had G4 or life threatening toxicities. Conclusion: The combination of cyclophosphamide and etoposide represents an efficient and tolerable treatment option for patients with metastatic osteosarcoma. 展开更多

AIM:To investigate perioperative outcomes in patients undergoing modified laparoscopic splenectomy and azygoportal disconnection(MLSD)with intraoperative autologous cell salvage.METHODS:We retrospectively evaluated outcomes in79 patients admitted to the Clinical Medical College of Yangzhou University with cirrhosis,portal hypertensive bleeding and secondary hypersplenism who underwent MLSD without(n=46)or with intraoperative cell salvage and autologous blood transfusion,including splenic blood and operative hemorrhage(n=33),between February 2012 and January 2014.Their intraoperative and postoperative variables were compared.These variables mainly included:operation time;estimated intraoperative blood loss;volume of allogeneic blood transfused;visual analog scale forpain on the first postoperative day;time to first oral intake;initial passage of flatus and off-bed activity;perioperative hemoglobin(Hb)concentration;and red blood cell concentration.RESULTS:There were no significant differences between the groups in terms of duration of surgery,estimated intraoperative blood loss and overall perioperative complication rate.In those receiving salvaged autologous blood,Hb concentration increased by an average of 11.2±4.8 g/L(P<0.05)from preoperative levels by the first postoperative day,but it had fallen by 9.8±6.45 g/L(P<0.05)in the group in which cell salvage was not used.Preoperative Hb was similar in the two groups(P>0.05),but Hb on the first postoperative day was significantly higher in the autologous blood transfusion group(118.5±15.8g/L vs 102.7±15.6 g/L,P<0.05).The autologous blood transfusion group experienced significantly fewer postoperative days of temperature>38.0℃(P<0.05).CONCLUSION:Intraoperative cell salvage during MLSD is feasible and safe and may become the gold standard for liver cirrhosis with portal hypertensive bleeding and hypersplenism. 展开更多

Although chemoradiotherapy (CRT) is one curative treatment option for patients with esophageal squamous cell carcinoma (ESCC), local failure after CRT remains a major problem for patients’ curability. The aim of this study was to evaluate the efficacy and safety of photodynamic therapy (PDT) as a salvage treatment for local failure. From August 2007 to March 2012, 193 consecutive ESCC patients were treated with definitive CRT in Kyoto University Hospital. Eighteen of the patients with T2 or earlier T-stage local failure after CRT underwent salvage PDT. After the salvage PDT, 11 patients (61.1%) achieved a complete response at the primary site. Over a median follow-up period of 28.3 months, the 1-year survival and progression-free survival rates were 77.8% and 38.9%, respectively;and the 2-year survival and progression-free survival rates were 60.6% and 33.3%, respectively. Adverse events were mild esophageal stricture in seven (38.9%), esophageal obstruction because of necrotic tissue in nine (50.0%), and photosensitivity in three (16.7%) patients. There were no severe complications or treatment-related deaths. Salvage PDT may be a promising treatment option for the patients with a local residual or recurrent tumor after CRT for ESCC when the lesion is suspected to be in T2 or earlier. 展开更多
