ABSTRACT
ABSTRACT Purpose: Salvage robotic-assisted radical prostatectomy (S-RARP) has gained prominence in recent years for treating patients with cancer recurrence following non-surgical treatments of Prostate Cancer. We conducted a systematic literature review to evaluate the role and outcomes of S-RARP over the past decade. Materials and Methods: A systematic review was conducted, encompassing articles published between January 1st, 2013, and June 1st, 2023, on S-RARP outcomes. Articles were screened according to PRISMA guidelines, resulting in 33 selected studies. Data were extracted, including patient demographics, operative times, complications, functional outcomes, and oncological outcomes. Results: Among 1,630 patients from 33 studies, radiotherapy was the most common primary treatment (42%). Operative times ranged from 110 to 303 minutes, with estimated blood loss between 50 to 745 mL. Intraoperative complications occurred in 0 to 9% of cases, while postoperative complications ranged from 0 to 90% (Clavien 1-5). Continence rates varied (from 0 to 100%), and potency rates ranged from 0 to 66.7%. Positive surgical margins were reported up to 65.6%, and biochemical recurrence ranged from 0 to 57%. Conclusion: Salvage robotic-assisted radical prostatectomy in patients with cancer recurrence after previous prostate cancer treatment is safe and feasible. The literature is based on retrospective studies with inherent limitations describing low rates of intraoperative complications and small blood loss. However, potency and continence rates are largely reduced compared to the primary RARP series, despite the type of the primary treatment. Better-designed studies to assess the long-term outcomes and individually specify each primary therapy impact on the salvage treatment are still needed. Future articles should be more specific and provide more details regarding the previous therapies and S-RARP surgical techniques.
ABSTRACT
Purpose: The aim of this study was to report the outcomes of panophthalmitis and to identify factors significantly affecting globe survival in the disease. Methods: This was a retrospective study on patients with panophthalmitis in a tertiary hospital between January 1, 2017, and December 31, 2019. The demographics, treatment details, culture results, and final outcomes were recorded. Logistic regression and Cox proportional hazards (CPH) were calculated to identify variables associated with globe loss. A P < 0.05 was considered significant. Results: Eighty?five eyes of 85 patients (31 culture positive) were eligible for review. The mean age of the participants was 55.21 ± 20.17 years with a male?to?female ratio of 2.04:1. Corneal ulcer (38.82%; n = 33) and open globe injuries (OGIs) (38.82%; n = 33) were the most common etiologies. Pseudomonas aeruginosa (n = 10; 11.76%) was the most common isolate. The mean duration of hospital stay was 7.58 ± 2.32 days. Overall, 44 (51.76%) globes could be salvaged. The need for evisceration (P = 0.901) and hospital stays (P = 0.095) were similar for culture?positive and ?negative cohorts. The unadjusted logistic regression and CPH models showed that culture sterility did not affect globe survival [OR = 1.210 (0.501– 2.950), P = 0.668; HR = 1.176 (0.617–2.243), P = 0.623]. The adjusted logistic regression and the CPH models showed that corneal ulcers [OR = 10.900 (2.460–48.200), P = 0.002; HR = 5.393 (1.603–18.140), P = 0.006] and OGI [OR = 7.360 (1.650–32.700), P = 0.009; HR = 4.548 (1.321–15.660), P = 0.016] were significantly associated with globe loss. Conclusion: Corneal ulcer or OGI as the primary etiology is detrimental to globe survival in panophthalmitis.
ABSTRACT
Background: Anterior staphyloma is defined as a localized defect in the anterior eye wall with protrusion of the uveal tissue due to alterations in scleral thickness and structure. The causes could be congenital, trauma, or following infection. Surgical options include staphylectomy with graft (corneal/ corneoscleral), biosynthetic graft, enucleation or evisceration in a painful blind eye). Purpose: To demonstrate staphylectomy with careful preservation of ocular structures followed by optical keratoplasty in a single setting. Synopsis: A 39?year?old Asian Indian lady presented with complaints of blurring of vision and whitish opacity in both eyes since childhood, associated with progressive enlargement and protrusion of the black part of the left eye with severe pain at the time of presentation. Her clinical examination revealed leucomatous corneal opacity in both the eyes and anterior staphyloma and keratinization in the left eye. Visual acuity was counting fingers close to face in the right eye and hand movements close to face in the left eye with projection of rays being accurate in both eyes. Ultrasound B scan showed posterior staphyloma in the right eye with sub?Tenon’s fluid and increased retinochoroidal thickness. The left eye posterior segment with B scan was normal. The available surgical options were evisceration with secondary orbital implant and ocular prosthesis or staphylectomy with corneal transplantation. To provide the best option for the patient in her eye with better visual potential, staphylectomy with corneal transplantation was done. Highlights: Painful blind eye is usually dealt with evisceration. This video demonstrates the technique of staphylectomy with corneal graft and restoration of structural integrity. Evisceration is a destructive procedure that involves removal of the intraocular contents. The patient will have to deal with the hassles of prosthesis maintenance and stigma of the artificial eye
ABSTRACT
Purpose: To describe the long?term outcomes of transcutaneous retrobulbar amphotericin B (TRAMB) in COVID?19?associated mucormycosis. Methods: In total, 18 cases of COVID?19?associated mucormycosis were reviewed. In addition to the recommended treatment protocol, all patients were to be given 3.5 mg/ml/day of TRAMB for five days. Results: Of the 18 patients, 2 presented with stage 3a disease, 13 had stage 3c disease, and 3 patients had central nervous system (CNS) involvement (stage 4a and 4c). In addition to planned retrobulbar doses, five patients were given more while two patients received fewer injections (i.e., <5). At the last mean follow?up of 34.67 (±8.88) weeks, 11 patients were in radiological regression and 4 had stable disease while 2 patients had to undergo exenteration; one mortality was observed because of disease progression. Clinical regression in terms of visual and ptosis improvement was seen in seven and nine patients, respectively. Conclusion: Rhino?orbito?cerebral mucormycosis is a serious condition which warrants an aggressive treatment strategy. In unprecedented situations witnessed recently, TRAMB turned out to be an effective and economical alternative. Though large randomized studies are needed to establish its efficacy, TRAMB still manages to halt progression and salvage the globe in significant number of patients, and hence its use should be encouraged on a case?to?case basis especially in developing countries with limited resources
ABSTRACT
Purpose: To evaluate the efficacy of secondary and salvage intra?arterial chemotherapy (IAC) as a globe salvage treatment modality in advanced and refractory intraocular retinoblastoma. Methods: A retrospective chart review of advanced intraocular retinoblastoma (groups D and E International Classification of Retinoblastoma [ICRB] classification) patients refractory to intravenous chemotherapy (IVC) and undergoing IAC as the secondary and salvage treatment modality between December 2018 and June 2021 was carried out. All patients underwent the IAC procedure by super?selective ophthalmic artery catheterization and with triple?drug chemotherapeutic agents of melphalan, topotecan, and carboplatin. Data were collected about tumor regression, eye salvage, metastasis, and survival outcome at follow?up. Results: Out of 13 patients, 12 patients received secondary IAC after being primarily treated with IVC and focal therapies and one patient received rescue IAC after recurrence following primary IAC. Mean number of IAC cycles administered was 2. Overall, globe salvage rate was 53.84%, with a mean follow?up of 17.53 months (range 6–37 months), three patients had enucleation for residual tumor or tumor recurrence. One patient developed metastasis post enucleation and two patients who were lost to follow?up after enucleation advice for residual tumor developed orbital tumor extension and eventually died of metastasis. Conclusion: Secondary triple?drug IAC following failure of IVC, along with other adjunct treatment modalities might a be a cost?effective option for eye salvage in advanced intraocular retinoblastoma patients who refuse enucleation, with a globe salvage rate of 53.84%. It can also be an effective approach to improve treatment compliance and can help in addressing the barrier of treatment refusal when enucleation is advised.
ABSTRACT
Objective:To investigate the efficacy of liposomal doxombicin combined with etoposide and high dose methylprednisolone (DEP) as a salvage therapy for refractory macrophage activation syndrome (MAS).Methods:Totally 38 patients with refractory MAS were enrolled in this study from January 2016 to January 2022 in Beijing Friendship Hospital, including clinical characteristics and laboratory test results before and after DEP treatment, were retrospectively collected. The efficacy was evaluated every 2 weeks according to the United States Midwest Cooperative HLH Group. Relevant samples were statistically analyzed using non-parametric tests.Results:Of 38 refractory MAS patients, 8 males and 30 females were included into this study.The median age was 30(15-69) years old. The underlying disease were adult onset Still's disease in 29 cases, Systemic lupus erythematosus in 6 cases, Rheumatoid arthritis in 1 case and Undifferentiated Connective-Tissue disease in 2. The overall response rate was 95% (36/38), including 9 patients (24%) achieved complete remission and 27 patients (71%) achieved partial remission after 2 weeks of treatment. The overall response rate was 97% (34/35), including 16 (46%) complete remission and 18 (51%) partial remission after 4 weeks of treatment(due to lack of data in some patients). The overall response rate was 97% (34/35), including 17 (49%) complete remission and 17 (49%) partial remission after 6 weeks of treatment. Patients who achieved partial remission or complete remission were actively treated for the underlying diseases after induction, and their conditions were in persistent remission.Conclusion:The DEP regimen may be an effective salvage therapy for the treatment of refractory MAS.
ABSTRACT
Objective:To explore the efficacy of tislelizumab combined with umbilical cord blood transplantation (UCBT) in relapsed/refractory acute myeloid leukemia (R/R AML) patients.Methods:The diagnosis and treatment of 1 patient with R/R AML who received tislelizumab bridging to UCBT after the failure of re-induction treatment in the First Affiliated Hospital of Soochow University in November 2021 was retrospectively analyzed.Results:The 59-year-old male patient with R/R AML achieved a complete remission after initial induction chemotherapy regimen of decitabine and venetoclax, and then additional consolidation therapy regimens of decitabine and middle-dose cytarabine, middle-dose cytarabine and idarubicin were performed. The patient relapsed 16 months later and failed to achieve a second remission after re-induction therapy regimens of cladribine, azacitidine, venetoclax combined with chemotherapy, and homoharringtonine, cytarabine combined with granulocyte colony-stimulating factor. Tislelizumab significantly reduced tumor burden and the patient achieved the complete remission after bridging to UCBT. After transplantation, the patient was given maintenance treatment with azacitidine and he had sustained remission without severe transplant-related complications during 9-month follow-up.Conclusions:The use of tislelizumab bridging UCBT can be a potential therapeutic strategy for R/R AML patients.
ABSTRACT
@#Introduction: Total femur replacement is an option instead of amputation for extensive bone tumour or after revision surgery with a massive bone loss. Over a long period of time the patients may need revision surgery, and this might affect the functional outcome. We reviewed all consecutive total femur replacements done for primary and revision surgery of primary bone tumours in our centre to evaluate the long-term functional outcome and survival. Materials and methods: All patients who had total femur resection and reconstruction with modular endoprosthesis replacement in our centre from June 1997 to May 2022 were reviewed. The respondents were surveyed through WhatsApp using google form which was translated into Bahasa Malaysia based on the Musculoskeletal Tumour Society Scoring System (MSTS). The data were presented as descriptive data on the final survival of the limb and prosthesis. Results: Ten patients underwent total femur replacement. There were eight osteosarcoma, one giant cell tumour and one chondromyxoid fibroma. Three patients with osteosarcoma succumbed to pulmonary metastases; all had good early post-operative functional outcomes without local recurrence. Seven patients were available for long term evaluation of function with a mean follow-up of 17.6 years (ranged 10-25 years). Four patients with total femur replacement had good functional outcomes (60-80%) without revision with 10-25 years follow-up. Three patients experienced acetabulum erosion and chronic pain that required early hip replacements. Two of them were complicated with superior erosions and bone loss and subsequently were managed with massive reconstruction using cemented acetabulum cage reconstruction. The other has diabetes mellitus with chronic infection following revision of distal femur endoprosthesis to total femur replacement and subsequently underwent limited hemipelvectomy after 14 years. Conclusion: Total femur replacement offers a good long term functional outcome and prosthesis survival and is a favourable option for limb salvage surgery.
ABSTRACT
【Objective】 To explore the effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage patients. 【Methods】 A study on postpartum hemorrhage patients undergoing cesarean section in the Third Affiliated Hospital of Guangxi Medical University form September 2016 to May 2022 was conducted retrospectively. A total of 137 patients were enrolled and divided into experimental group (n=70) and control group (n=67) according to whether intraoperative cell salvage was used during operation. The blood loss, proportion and volume of allogeneic red blood cells (RBCs) and coagulation component transfusion, hemoglobin (Hb) level, coagulation function, electrolyte, the incidence of complications, proportion of ICU admission, ICU stay and in-hospital stay were compared between the two groups. 【Results】 The proportion of patients receiving allogeneic RBCs in the experimental group and in the control group was 31.4% vs 100.0% (P0.05). 【Conclusion】 This study demonstrated that intraoperative cell salvage could reduce the requirement for allogeneic RBCs without compromising coagulation function in postpartum hemorrhage patients undergoing cesarean section, but the changes of calcium need to be concerned after transfusion.
ABSTRACT
Objective:To evaluate the effect of intraoperative cell salvage (ICS) on the number and viability of cancer cells in salvaged autologous blood from the patients undergoing liver cancer surgery.Methods:Twenty patients undergoing open radical primary hepatocellular carcinoma were selected, and blood from the operative field was collected after exposing the liver and treated with ICS. Blood specimens 20 ml from the surgical field (S 1), blood specimens 20 ml before ICS treatment-leukocyte depletion filter (LDF) filtration (S 2) and blood specimens 20 ml after LDF filtration (S 3) were collected and enriched, of which the blood sample 10 ml was used for cancer cell identification and count by immunofluorescence staining, and the remaining blood sample 10 ml was continuously cultured for 3 weeks, and then cell viability was observed by immunofluorescence method. Results:Hepatocellular carcinoma(HCC) cells were identified in 19 S 1 specimens, 18 S 2 specimens, and 16 S 3 specimens, but there was no significant difference in the detection rate among the three specimens ( P>0.05). Compared with S 1 specimens, HCC cell count was significantly reduced in S 2 and S 3 specimens ( P<0.05). There was no significant difference in the HCC cell count between S 3 specimens and S 2 specimens ( P>0.05). After 3 weeks of culture, the results of light microscopy showed that: hepatocellular carcinoma cell clusters were found in S1 specimens, and no hepatocellular carcinoma cell cluster was found in S 2 and S 3 specimens; the results of fluorescence microscopy showed that: 400 and 14 mixed epithelial-mesenchymal HCC cells and 100 and 21 mesenchymal HCC cells were found in S 1 and S 2 specimens, respectively, while no HCC cells were identified in S 3 specimens, among which HCC cells mainly presented as clusters of hepatocellular carcinoma cells in S 1 specimen, while no clusters of hepatocellular carcinoma cells were found in S 2 and S 3 specimens. Conclusions:After treatment with ICS or ICS-LDF, the number and viability of hepatocellular carcinoma cells in salvaged autologous blood are significantly reduced, and hepatocellular carcinoma cells exist as single cells and fail to develop clusters of hepatocellular carcinoma cells; LDF can reduce the risk of hepatocellular carcinoma cell autotransfusion to a certain extent, although it can not effectively filter out hepatocellular carcinoma cells continuously.
ABSTRACT
Objective:To describe the design, manufacture and use of three-dimensional (3D)-printed endoprosthesis for reconstruction after metaphysis-involved intercalary tumor resection and to evaluate its outcome.Methods:Forty-three patients who received metaphysis-involved intercalary tumor resection followed by 3D-printed endoprosthetic reconstruction in Musculoskeletal Tumor Center, Peking University People's Hospital between January 2018 and December 2021 were retrospectively reviewed. There were 25 males and 18 males with an average age of 20.1±15.2 years (range, 4-58 years). The pathological diagnosis included 24 cases of osteosarcomas, 6 cases of Ewing sarcomas, 5 cases of chondrosarcomas, 2 cases of pleomorphic undifferentiated sarcomas, 3 cases of soft-tissue sarcomas (liposarcoma, synovial sarcoma, malignant peripheral nerve sheath tumor for each) and 3 others (adamantinoma, recurrent aneurysmal bone cyst and recurrent osteofibrous dysplasia for each). The tumors located at femur in 25 patients (58%), including 14 lesions involving distal femoral metaphysis and 11 lesions involving both proximal and distal metaphysis; the tumors located at tibia in 11 patients (26%), including 4 lesions involving distal tibial metaphysis, 5 lesions involving proximal tibial metaphysis and 2 lesions involving both proximal and distal tibial metaphysis; the tumors located at humerus in 7 patients (16%), including 1 lesion involving distal humeral metaphysis, 3 lesions involving proximal humeral metaphysis and 3 lesions involving both proximal and distal humeral metaphysis. The endoprosthesis was designed in a semi-modular fashion and consisted of three parts: a diaphysis-fixing component, a semi-modular lap joint component, and a custom-made 3D-printed metaphysis-fixing component which was designed as two types with 3D-printed porous bone-contacting surfaces according to the osteotomy plane (Type I on meta-diaphyseal region, Type II on meta-epiphyseal region). The functional outcome was assessed using Musculoskeletal Tumor Society (MSTS) 93 system.Results:All surgeries were accomplished sucessfully. The median resection length and the distance from osteotomy plane to adjacent joint was 16.0 (13.0, 22.0) cm and 4.5 (3.5, 6.0) cm, respectively. 59 metaphysis-fixing components were installed in 43 patients. Type I components were used in single and dual ends of endoprosthesis in 12 and 6 cases respectively. Type II components were used in single and dual ends in 15 and 5 cases respectively. Hybrid endoprosthesis with Type I and II components were used in 5 cases. The mean follow-up time was 26.0 (17, 37) months (range, 12-54 months). The mean MSTS 93 score was 29.0 (28.0, 30.0) points (range, 21-30 points). Implant failures were found in 5 patients, including 2 cases of aseptic loosening (loosening was observed in the cementing diaphysis-fixing stems while no evidence of loosening in metaphysis-fixing components) and 3 cases of local tumor progression. The 2-year implant survival rate was 90.3% (95% CI: 0.81, 0.99). Conclusion:Using 3D-printed intercalary endoprosthesis for reconstruction after intercalary resection of metaphysis-involved bone tumor shows satisfactory functional outcome and implant survival. Moreover, by assembling endoprosthetic components according to the different osteotomy plane, the semi-modularized endoprosthesis also provids a comprehensive and individualized reconstruction for patients with metaphysis-involved intercalary tumor.
ABSTRACT
Proximal humerus fractures are common problems plaguing in geriatric population. Approximately half of all proximal humeral fractures occur due to fall usually at ground level. (Low velocity trauma). In younger individuals fractures occurring because of higher-energy trauma such as a fall from a height, motor vehicle accidents, sports, or assaults. The proximal humerus fracture because of three loading modes: compressive loading of the glenoid onto the humeral head, bending forces at the surgical neck, and tension forces of the rotator cuff at the greater and lesser tuberosities. Most proximal humeral fractures are treated nonoperatively. However, surgical treatment is becoming more popular, with development of modern implant (PHILOS plate). Implant failure is common complication occur due to improper fixation, osteoporotic bone, early mobilization, non-union and varus malalignment. Various modality available for its management i.e., Hemiarthroplasty, reverse shoulder arthroplasty and ORIF + bone graft. IN this case report 60-year male patient with right side proximal humerus fracture treated with PHILOS plating. At 6 week follow up radiograph suggest implant failure. Patient was posted for revision surgery ORIF + platting and fibular strut graft was done.
ABSTRACT
Abstract Objective To evaluate the survival time, the failure rate and its causes, and the functional results of cemented endoprostheses, with a polyethylene body, used after resection of primary bone tumors of the distal femur. Methods A retrospective study including 93 primary and 77 review procedures performed between 1987 and 2014. Survival was obtained by the Kaplan Meyer analysis, and the risk factors for implant failure were assessed through the Cox proportional risk model. The causes of endoprosthesis failure were classified according to Henderson et al. into five types: soft-tissue failure, aseptic loosening, structural fracture, infection, and tumor recurrence. The functional evaluation was performed using the functional classification system of the Musculoskeletal Tumor Society (MSTS) of bone sarcomas of the lower extremity, Brazilian version (MSTS-BR). Results Osteosarcoma was the most common diagnosis; 64.5% of the patients were younger than 20 years of age; the mean follow-up was of 124.3 months. The failure rate of the primary implant was of 54.8%, and the mean survival was of 123 months. The estimated survival of the primary implant was of 63.6%, 43.5%, 24.1%, and 14.5% in 5, 10, 15, and 20 years respectively. The most common cause of failure was type 2 (37.3%). Age ≤ 26 years and right side were risk factors for failure. The mean MSTS-BR score was of 20.7 (range: 14 to 27). Conclusion The results obtained for the failure rate and survival of the implant are in accordance with those of the literature, so the procedure herein studied is adequate and yields satisfactory functional results, even in the long term.

Background: The presence of adverse pathological features like extraprostatic extension, seminal vesicle involvement, or positive margins at radical prostatectomy incurs a high risk of postoperative recurrence. Currently, adjuvant radiotherapy (ART) is the standard of care in these patients, while early salvage radiotherapy (eSRT) is a potential alternative strategy. Aims: The purpose of this paper is to review the latest evidence comparing outcomes of adjuvant versus early SRT in this clinical scenario. Materials and Methods: A systematic review of Google Scholar, PubMed/Medline, and EMBASE was done to identify relevant studies published in the English language, regarding outcomes of adjuvant radiotherapy and early SRT in post radical prostatectomy patients. Twelve studies, including six randomized trials, four retrospective studies, one systematic review, and one metanalysis were included in the final analysis. Results: We found that initial randomized trials demonstrated better event?free survival with adjuvant radiotherapy when compared to observation alone. However, ART was associated with increased risk of overtreatment and thus increased radiation?related toxicity rates. Conclusion: Preliminary evidence from recently reported RCTs suggests that eSRT may provide equivalent oncological outcomes to ART in prostate cancer patients with adverse pathology on radical prostatectomy while decreasing unnecessary treatment and radiation?related toxicity in a significant proportion of patients. However, the final verdict would be delivered after the long?term metastasis?free survival and overall survival outcomes are available.
ABSTRACT

El resultado funcional medio de la escala MSTS fue de 72.5% (rango: 40-95%) y la tasa de complicaciones de 56.7% (17 pacientes), siendo la recurrencia tumoral (29%) la principal complicación. Conclusión: La reconstrucción mediante megaprótesis ofrece buenos resultados funcionales a los pacientes dentro de la cirugía de resección radical, permitiendo realizar una vida relativamente normal.
Abstract: Introduction: Radical resection is the surgical treatment of choice in musculoskeletal malignancies, which often settle in the pelvis and lower limbs. Megaprothesis reconstruction has been imposed in recent years as the gold standard in limb preservation surgery. Material and methods: Descriptive retrospective study series of cases, including 30 patients operated between 2011 and 2019 of musculoskeletal pelvic and lower limb tumors at our institution that underwent limb-sparing reconstruction with the megaprosthesis. Functional results according to the MSTS (Musculoskeletal Tumor Society) index and complication rate were analyzed. Results: The average follow-up was 40.8 months (12-101.7). Nine patients (30%) underwent pelvic resections and reconstructions, 11 patients (36.7%) underwent hip reconstruction with megaprothesis due to femoral involvement, in three patients (10%) complete femur resection was performed, and seven patients (23.3%) underwent prosthetic reconstruction of the knee. The mean MSTS score was 72.5% (range: 40-95%), and the complication rate was 56.7% (17 patients), being de tumoral recurrence (29%) the main complication. Conclusion: Tumor megaprothesis give satisfying functional results, allowing the patients to realize a relatively normal life after a lower limb-sparing surgery.

Background: Anterior staphyloma is defined as a localized defect in the anterior eye wall with protrusion of the uveal tissue due to alterations in scleral thickness and structure. The causes could be congenital, trauma, or following infection. Surgical options include staphylectomy with graft (corneal/ corneoscleral), biosynthetic graft, enucleation or evisceration in a painful blind eye). Purpose: To demonstrate staphylectomy with careful preservation of ocular structures followed by optical keratoplasty in a single setting.

ABSTRACT
Coats’ disease is associated with poor outcomes, and there are limited studies on long?term outcomes of Coats’ disease. The purpose of our study is to identify various predictive factors to help in prognosticating the treatment outcomes in advanced Coats’ disease in children. Methods: This is a retrospective case series from a single tertiary eye care center of children (<18 years) diagnosed with coat’s disease. Sixty?seven patients with Coat’s disease were identified from the medical records from 2009 to 2020. Patients’ demographic data, clinical presentation, stage, extent of involvement, detailed treatment history, clinical sequelae post?treatment (including complications and anatomical and functional outcomes) were noted. Binary logistic regression was performed to correlate the predictive factors for anatomical and functional improvement. Results: Of the 67 patients, 51 eyes of 51 patients were included in the study. The male to female proportion was 2.2. Mean age at presentation was 4.98 ± 3.55 years (range: 2 months–15 years). Mean duration of follow?up was 31.53 ± 26.38 months. Overall, our globe salvage rate was 92.2%. We found that vitreoretinal fibrosis (P < 0.001), subretinal gliosis (P < 0.001), vitreous hemorrhage (P = 0.02), tractional or combined retinal detachment (P < 0.001), foveal scar (P < 0.006), and cataract (P < 0.001) to be important factors to affect the outcome. Conclusion: Advanced stage of presentation (stage 3B and above), diffuse involvement, cataract, vitreoretinal fibrosis (preretinal and subretinal), vitreous hemorrhage, tractional or combined retinal detachment, and anterior hyaloid proliferation are poor prognostic factors for globe salvage in advanced disease. Subretinal gliotic nodule or scar and lack of visual rehabilitation suggest poor functional outcomes
ABSTRACT
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. At present, hepatectomy is one of the most frequent therapeutic options, whereas the high postoperative recurrence rate severely affects the long-term survival of HCC patients. Therefore, it is urgent to choose appropriate therapeutic regime to treat the recurrence of HCC to improve the long-term survival of HCC patients. Surgical treatment is an efficacious treatment for recurrent HCC, including re-hepatectomy, salvage liver transplantation and radiofrequency ablation. Currently, individualized treatment is recommended for postoperative recurrence of HCC. The selection of treatment should be conducted based on the tumor conditions after the first hepatectomy, the characteristics of recurrent tumors, baseline data of patients and recurrence time, etc., aiming to formulate appropriate treatment regimes for patients. In this article, these surgical regimes were reviewed and compared to explore appropriate surgical schemes for postoperative recurrence of HCC, aiming to provide reference for prolonging the survival of HCC patients.
ABSTRACT
Objective:To compare the prognoses of salvage liver transplantation fulfilling the Criteria of Milan, University of California San Francisco(UCSF)and Hangzhou.Methods:Clinical data were retrospectively reviewed for 256 patients with recurrent hepatocellular carcinoma(HCC)undergoing donation after citizen death(DCD)liver transplantation(LT)from January 2015 to October 2019.They were divided into two groups of primary(PLT, n=175)and salvage(SLT, n=81). General profiles, tumor pathological characteristics and postoperative complications of two groups were compared by T-test, rank-sum or χ2 test.Kaplan-Meier method and Log rank test were employed for comparing overall survival rate(OS)and recurrence-free survival rate(RFS)between two groups.In SLT group, 31 cases fulfilled Milan criteria, 45 cases UCSF criteria and 69 cases Hangzhou criteria.OS/RFS of three groups were compared.According to there was downstaging or bridging treatment pre-LT, SLT group was divided into downstaging group(n=32)and non-downstaging group(n=49). OS/RFS of two groups were compared.According to the Rescit1.1 criteria, downstaging group were divided into remission group(n=14)and non-remission group(n=18)and OS/RFS of two groups were compared. Results:The operative durations of PLT and SLT groups were(439.5±74.9)and(475.1±83.4)min respectively.There was significant inter-group difference( P<0.05); However, no significant inter-group difference existed in amount of intraoperative bleeding, blood transfusion, postoperative hospital stay or incidence of postoperative complications(all P>0.05). No significant difference existed in OS/RFS between PLT and SLT groups( P>0.05). No significant difference existed in OS at 1/3/5 years post-SLT among Milan, UCSF and Hangzhou criteria groups(all P>0.05); However, RFS in Milan criteria group at 1/3/5 years post-SLT were 93.5%, 81.7% and 81.7% respectively.They were significantly higher than 68.9%, 59.7% and 59.7% in UCSF criteria group and 78.3%, 58.8% and 55.5% in Hangzhou criteria group(all P<0.05). For patients on downstaging therapy, OS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 73% and 73% respectively, which was significantly higher than 83.3%, 49.4% and 0 in non-Remission group( P=0.042). RFS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 62.5% and 46.9% respectively, which was significantly higher than 52.9%, 0 and 0 in no-Remission group( P=0.001). Conclusions:The survival outcome of SLT recipients is similar to that of PLT recipients.The overall survival of SLT recipients shows no significant difference between Milan, UCSF and Hangzhou criteria.However, SLT recipients fulfilling Milan criteria have the longest recurrence-free time.The prognosis of patients with remission after preoperative descending treatment is superior to that of patients without remission.
ABSTRACT
Objective:To explore the effect of intraoperative blood salvage (IBS) in the operation of infective endocarditis (IE) and the risk factors of death within half a year after operation.Methods:Used retrospective research methods, a total of 61 patients who were diagnosed as IE and received surgical treatment in Department of Cardiovascular and Large Vascular Surgery, Huizhou Central People′s Hospital from April 2017 to November 2020 were selected as subjects. The patients were divided into autologous group ( n=30) and allogeneic group ( n=31) according to different blood transfusion methods. Patients in the autogenous group received IBS, and patients in the allogeneic group received allogeneic blood transfusion. The indexes of coagulation function [activated partial thromboplastin time(APTT), thrombin tim(TT), prothrombin time(PT), D-dimmer(D-D), fibrinogen degradation product(FDP)], immune reaction (CD3 + CD4 + T cells, CD3 + CD8 + T cells, CD16 + CD56 + NK cells, TLR2 + cells, TLR4 + cells) and inflammatory reaction [soluble CD40 ligand(sCD40L), neutrophil chemokine -1(CINC-1), tumor necrosis factor-α(TNF-α), interleukin-6(IL-6)] were compared between the autologous group and the allogeneic group, as well as the incidence of postoperative adverse reactions. The end event was death half a year after operation, and the subjects were divided into death group ( n=15) and survival group ( n=46). The clinical data of the death group and the survival group were compared. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups; Chi-square test was used for comparison of enumeration data between groups, and the IBS variables were included and excluded to establish the prediction models of death half a year after operation, respectively. The model was evaluated by the receiver operating characteristic curve (ROC), and the model was internally verified by the method of Bootstrap repeated sampling. IBS was included and removed to establish the prediction model of death within half a year after surgery, and ROC was used to evaluate the model. Bootstrap repeated sampling was used to verify the model internally. Results:Cardiac insufficiency, hypotension, IBS, multivalvular disease and age were independent risk factors for postoperative death ( P<0.05). The model with IBS variables has higher predictive value. 5 days after operation, there were significant differences in the indexes of immune reaction [CD3 + CD4 + T cells: (37.49±5.74)% vs (31.68±4.46)%, CD3 + CD8 + T cells: (23.07±3.24)% vs (17.82±2.29)%, CD16 + CD56 + NK cells: (1.61±0.18)% vs (1.02±0.15)%, TLR2 + cells: (9.24±1.15)% vs (18.40±2.21)%, TLR4 + cells: (7.79±0.82)% vs (12.33±1.57)%] and inflammatory reaction [sCD40L: (59.21±7.80) pg/mL vs (84.33±9.35) pg/mL, CINC-1: (40.27±5.83) pg/mL vs (72.86±9.35) pg/mL, TNF-α: (10.86±1.26) ng/mL vs (17.03±2.20) ng/mL and IL-6: (6.32±0.77) ng/mL vs (11.35±1.74) ng/mL] between autologous group and allogeneic group ( P<0.01). Intra-group comparison of patients in autologous group, before and 5 days after operation, there were significant differences in the indexes of immune response [CD3 + CD4 + T cells: (48.55±6.67)% vs (37.49±5.74)%, CD3 + CD8 + T cells: (30.38±4.69)% vs (23.07±3.24)%, CD16 + CD56 + NK cells: (2.53±0.44)% vs (1.61±0.18)%, TLR2 + cells: (6.50±0.61)% vs (9.24±1.15)%, TLR4 + cells: (4.02±0.63)% vs (7.79±0.82)%] and inflammatory response [sCD40L: (38.64±6.75) pg/mL vs (59.21±7.80) pg/mL, CINC-1: (31.65±5.68) pg/mL vs (40.27±5.83) pg/mL, TNF-α: (7.59±0.85) ng/mL vs (10.86±1.26) ng/mL and IL-6 (5.10±0.63) ng/mL vs (6.32±0.77) ng/mL] ( P<0.01). Intra-group comparison of patients in allogeneic group, before and 5 days after operation, there were significant differences in the indexes of immune reaction [CD3 + CD4 + T cells: (49.13±6.82)% vs (31.68±4.46)%, CD3 + CD8 + T cells: (30.65±4.91)% vs (17.82±2.29)%, CD16 + CD56 + NK cells: (2.51±0.26)% vs (1.02±0.15)%, TLR2 + cells: (6.36±0.66)% vs (18.40±2.21)%, TLR4 + cells (4.08±0.56)% vs (12.33±1.57)%] and inflammatory response [sCD40L: (39.14±6.03) pg/mL vs (84.33±9.35) pg/mL, CINC-1: (31.24±5.77) pg/mL vs (72.86±9.35) pg/mL, TNF-α: (7.64±0.76) ng/mL vs (17.03±2.20) ng/mL and IL-6: (5.04±0.82) ng/mL vs (11.3±1.74) ng/mL] ( P<0.01). There were 3 cases of hypoproteinemia, 2 cases of incision infection and 1 case of cardiac adverse event in the autologous group; 4 cases of hypoproteinemia, 3 cases of incision infection and 1 case of cardiac adverse event in the allogeneic group. There was no significant difference in the incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:The predictive model included in IBS can better predict the mortality of within half a year after IE. The use of IBS in IE surgery will not significantly affect the blood coagulation function and the incidence of postoperative adverse reactions, but can improve immune function and inhibit inflammatory reaction.
