RESUMO

Patients with advanced esophageal squamous cell carcinoma (SCC) have a poor prognosis when treated with standard chemotherapy. Programmed death ligand 1 (PD-L1) expression in esophageal cancer has been associated with poor survival and more advanced stage. Immune checkpoint inhibitors, such as PD-1 inhibitors, showed benefits in advanced esophageal cancer in clinical trials. We analyzed the prognosis of patients with unresectable esophageal SCC who received nivolumab with chemotherapy, dual immunotherapy (nivolumab and ipilimumab), or chemotherapy with or without radiotherapy. Patients who received nivolumab with chemotherapy had a better overall response rate (ORR) (72% vs. 66.67%, p = 0.038) and longer overall survival (OS) (median OS: 609 days vs. 392 days, p = 0.04) than those who received chemotherapy with or without radiotherapy. In patients receiving nivolumab with chemotherapy, the duration of the treatment response was similar regardless of the treatment line they received. According to clinical parameters, liver and distant lymph nodes metastasis showed a trend of negative and positive impacts, respectively, on treatment response in the whole cohort and in the immunotherapy-containing regimen cohort. Nivolumab add-on treatment showed less gastrointestinal and hematological adverse effects, compare with chemotherapy. Here, we showed that nivolumab combined with chemotherapy is a better choice for patients with unresectable esophageal SCC.

RESUMO

Favorable prognostic factors and therapeutic strategies are important for patients with single large hepatocellular carcinoma (HCC). This retrospective study aimed to investigate the prognostic factors in patients with single large (≥5 cm) HCC with Child-Pugh (CP) class A patients and to recommend therapeutic strategies. Overall, 298 HCC patients with single and large (≥5 cm) tumors with CP class A, but without distant metastasis and macrovascular invasion were included, and their clinicopathological data, overall survival (OS), and progression-free survival (PFS) were recorded. OS and PFS was analyzed by the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed. The 298 HCC patients were 79.2% male and median age of 64 years. For the initial treatment, surgical resection (SR) and transarterial chemoembolization (TACE) was 50.8% and 49.2%, respectively. The OS and PFS were significantly higher in patients receiving SR than those receiving TACE before and after PSM. Furthermore, in multivariate analysis, cirrhosis (Hazard ratio [HR]: 2.04; 95% confidence interval [CI]: 1.35-3.03, p < 0.001, CP class A5/6 [HR: 4.01; 95% CI: 2.43-6.66, p < 0.001], and initial treatment [SR vs. TACE HR = 3.23; 95% CI: 2.13-5.01, p < 0.001]) remained significantly associated with mortality. Moreover, in multivariate analysis, CP class A5/6 (HR: 3.23; 95% CI: 1.89-5.88, p < 0.001), and initial treatment (Resection vs. TACE; HR = 4.17; 95% CI: 1.64-8.33, p = 0.039) remained significantly associated with recurrence. In conclusion, SR was associated with significantly higher OS and PFS rates than TACE before and after PSM for single large HCC patients.

RESUMO

BACKGROUND: The detection rate of Barcelona Clinic Liver Cancer (BCLC) very-early-stage hepatocellular carcinoma (HCC) is increasing because of advances in surveillance and improved imaging technologies for high-risk populations. Surgical resection (SR) and radiofrequency ablation (RFA) are both first-line treatments for very-early-stage HCC, but the differences in clinical outcomes between patients treated with SR and RFA remain unclear. This study investigated the prognosis of SR and RFA for very-early-stage HCC patients with long-term follow-up. METHODS: This study was retrospectively collected data on the clinicopathological characteristics, overall survival (OS), and disease-free survival (DFS) of 188 very-early-stage HCC patients (≤ 2 cm single HCC). OS and DFS were analyzed using the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed. RESULTS: Of the 188 HCC patients, 103 received SR and 85 received RFA. The median follow-up time was 56 months. The SR group had significantly higher OS than the RFA group (10-year cumulative OS: 55.2% and 31.3% in the SR and RFA groups, respectively). No statistically significant difference was observed in DFS between the SR and RFA groups (10-year cumulative DFS: 45.9% and 32.6% in the SR and RFA groups, respectively). After PSM, the OS in the SR group remained significantly higher than that in the RFA group (10-year cumulative OS: 54.7% and 42.2% in the SR and RFA groups, respectively). No significant difference was observed in DFS between the SR and RFA groups (10-year cumulative DFS: 43.0% and 35.4% in the SR and RFA groups, respectively). Furthermore, in the multivariate Cox regression analysis, treatment type (hazard ratio (HR): 0.54, 95% confidence interval (CI): 0.31-0.95; P = 0.032) and total bilirubin (HR: 1.92; 95% CI: 1.09-3.41; P = 0.025) were highly associated with OS. In addition, age (HR: 2.14, 95% CI: 1.36-3.36; P = 0.001) and cirrhosis (HR: 1.79; 95% CI: 1.11-2.89; P = 0.018) were strongly associated with DFS. CONCLUSION: For patients with very-early-stage HCC, SR was associated with significantly higher OS rates than RFA. However, no significant difference was observed in DFS between the SR and RFA groups.

RESUMO

BACKGROUND: The benefits of surgical resection (SR) for various Barcelona Clinic Liver Cancer (BCLC) stages of hepatocellular carcinoma (HCC) remain unclear. We investigated the risk factors of overall survival (OS) and survival benefits of SR over nonsurgical treatments in patients with HCC of various BCLC stages. METHODS: Overall, 2316 HCC patients were included, and their clinicopathological data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Propensity score matching (PSM) analysis was performed. RESULTS: In total, 66 (2.8%), 865 (37.4%), 575 (24.8%) and 870 (35.0%) patients had BCLC stage 0, A, B, and C disease, respectively. Furthermore, 1302 (56.2%) of all patients, and 37 (56.9%), 472 (54.6%), 313 (54.4%) and 480 (59.3%) of patients with BCLC stage 0, A, B, and C disease, respectively, died. The median follow-up duration time was 20 (range 0-96) months for the total cohort and was subdivided into 52 (8-96), 32 (1-96), 19 (0-84), and 12 (0-79) months for BCLC stages 0, A, B, and C cohorts, respectively. The risk factors for OS were (1) SR and cirrhosis; (2) SR, cirrhosis, and Child-Pugh (C-P) class; (3) SR, hepatitis B virus (HBV) infection, and C-P class; and (4) SR, HBV infection, and C-P class for the BCLC stage 0, A, B, and C cohorts, respectively. Compared to non-SR treatment, SR resulted in significantly higher survival rates in all cohorts. The 5-year OS rates for SR vs. non-SR were 44.0% versus 28.7%, 72.2% versus 42.6%, 42.6% versus 36.2, 44.6% versus 23.5%, and 41.4% versus 15.3% (all P values < 0.05) in the total and BCLC stage 0, A, B, and C cohorts, respectively. After PSM, SR resulted in significantly higher survival rates compared to non-SR treatment in various BCLC stages. CONCLUSIONS: SR conferred significant survival benefits to patients with HCC of various BCLC stages and should be considered a recommended treatment for select HCC patients, especially patients with BCLC stage B and C disease.

RESUMO

The efficacy of sorafenib in combination with transarterial chemoembolization (TACE) or multiple-line therapies in patients with advanced hepatocellular carcinoma (HCC) remains unclear. This study aimed to investigate the overall survival (OS) of patients with advanced HCC in response to different combination therapies.We analyzed the treatment and OS of 401 patients with Barcelona clinic liver cancer stage C HCC between 2012 and 2017. Mortality was analyzed using multivariate Cox regression, and OS was analyzed by the Kaplan-Meier method.The mean age was 59 years and males were predominant. During a median follow-up time of 8.6 months (range, 1-80 months), 346 (86.2%) patients died. In the multivariate Cox regression analysis, primary tumor size ≥5 cm, serum alpha-fetoprotein ≥200, and serum albumin ≥3.5 were significantly associated with mortality. In addition, compared with sorafenib alone, multiple-line treatments with sorafenib and multiple-line treatments without sorafenib yielded significantly decreased mortality. In the Kaplan-Meier analysis, sorafenib with TACE, multiple-line treatments with sorafenib, third-line treatments with sorafenib, and multiple-line treatments without sorafenib yielded a significantly better median OS than sorafenib alone.Sorafenib with concurrent multiple-line therapies significantly improved OS. These combination therapies will provide important information for immunotherapy combination with locoregional therapies in advanced HCC.

RESUMO

Synthetic lethality arises when a combination of mutations in two or more genes leads to cell death. However, the prognostic role of concordant overexpression of synthetic lethality genes in protein level rather than a combination of mutations is not clear. In this study, we explore the prognostic role of combined overexpression of paired genes in lung adenocarcinoma. We used immunohistochemical staining to investigate 24 paired genes in 93 lung adenocarcinoma patients and Kaplan-Meier analysis and Cox proportional hazards models to evaluate their prognostic roles. Among 24 paired genes, only FEN1 (Flap endonuclease 1) and RAD54B (RAD54 homolog B) were overexpressed in lung adenocarcinoma patients with poor prognosis. Patients with expression of both FEN1 and RAD54B were prone to have advanced nodal involvement and significantly poor prognosis (HR = 2.35, P = 0.0230). These results suggest that intensive follow up and targeted therapy might improve clinical outcome for patients who show expression of both FEN1 and RAD54B.

RESUMO

INTRODUCTION: A superior lumbar hernia, which is also known as a Grynfeltt hernia, is a rare abdominal wall defect that can be primary or secondary to trauma or orthopedic surgery. The anatomic location of a lumbar hernia makes diagnosis and repair challenging. We successfully repaired a lumbar hernia using a single-incision laparoscopic total extraperitoneal approach. To the best of our knowledge, this is the first report of the use of this surgical technique in the treatment of a primary Grynfeltt hernia. CASE PRESENTATION: A 76-year-old Taiwanese man presented to our hospital with a left lower bulging mass noted for over three months. Abdominal computed tomography revealed a left Grynfeltt hernia. We performed a single-incision laparoscopic total extraperitoneal repair. Our patient was discharged uneventfully on the fourth day after the operation. There was no evidence of recurrence after six months of follow-up. CONCLUSION: A laparoscopic total extraperitoneal repair for a lumbar hernia provides an excellent operative view and minimal invasiveness. The single-incision technique also provides better cosmetic outcomes. Our experience suggests that the single-incision laparoscopic total extraperitoneal approach may be a feasible and safe alterative to conventional approaches in lumbar hernia repair.

RESUMO

BACKGROUND: McBurney's incisional hernia after appendectomy is rare. Although the open surgical approach, either through direct suturing or through mesh repairs, mostly achieves a satisfactory outcome, postoperative wound pain usually impedes patient's early ambulation. Accordingly, laparoscopic ventral hernia repair has emerged as a minimally invasive technique in modern surgical practice. We described a different approach of laparoscopic incisional hernia repair. CASE REPORT: A 76-year-old woman with a history of appendectomy presenting with a bulging mass over the right lower quadrant of the abdomen beneath the operation scar was admitted to our hospital. Computed tomography revealed defects in the abdominal muscle layers without evidence of bowel incarceration. The patient was diagnosed with postappendectomy incisional hernia for which laparoscopic hernia repair was performed through a combined intraperitoneal and extraperitoneal approach. The patient's postoperative course was excellent. CONCLUSIONS: Combined extraperitoneal approach and intraperitoneal monitoring for McBurney's incisional hernia is feasible in selected cases.

RESUMO

BACKGROUND: Post-thyroidectomy tracheomalacia is a rare but complicated problem. It has often been treated with tracheostomy or prolonged endotracheal intubation. However, noninvasive positive pressure ventilation (NPPV) has been successfully employed with increasing frequency in patients with respiratory failure from other causes. In the present study we describe the use of NPPV in the management of respiratory distress in patients with post-thyroidectomy tracheomalacia. METHODS: All 606 patients who underwent thyroidectomy in Chung Gung Memorial Hospital - Kaohsiung Medical Center, Taiwan, from January 2009 to August 2010 were reviewed. If tracheomalacia was diagnosed intraoperatively, the patients were left intubated and taken to the intensive care unit (ICU) (n = 5). If tracheomalacia was diagnosed in the recovery room (stridor and airway compromise not from other causes), the patient was reintubated promptly and taken to the ICU (n = 4). When subsequently re-extubated in the ICU (24-72 h later), NPPV was used to treat recurrent stridor and airway compromise. RESULTS: A total of nine patients (1.5 %) were diagnosed with post-thyroidectomy tracheomalacia, five intraoperatively and four postoperatively. The patients were intubated with an endotracheal tube and then taken to the ICU. After early re-extubation in the ICU, three of the patients with intraoperatively diagnosed tracheomalacia were found not to have respiratory problems, whereas the other six patients developed stridor and airway compromise, which resolved immediately with the initiation of NPPV. Hemoglobin oxygen saturation on pulse oximetry was also elevated. No further respiratory support was required and no complications occurred in these patients. CONCLUSIONS: Noninvasive positive pressure ventilation is effective and appears safe in the management of stridor and airway compromise following early extubation in patients with post-thyroidectomy tracheomalacia.

RESUMO

Overexpression of Id family proteins inhibits cell differentiation and enhances cell proliferation and invasiveness. Although Id1 is the Id family member mostly linked to tumorigenesis, its role in lung cancer is unclear. An elevated Id1 expression was observed in lung cancer cell lines as well as lung cancer tissues. Id1 overexpression increased cell proliferation while Id1 knockdown decreased cell proliferation, mostly through Akt-related pathway. Nude mice study further confirmed an increased tumor growth in Id1-overexpressing cells and a decreased tumor growth in Id1-knockdowned cells. In conclusion, inactivation of Id1 may provide a novel strategy for treatment of lung cancer patients.

RESUMO

The protoapigenone analogue WYC02-9, a novel synthetic flavonoid, has been shown to act against a variety of experimental tumors. However, its effects on prostate cancer and its mechanism of action are unknown. Thus, WYC02-9 was investigated for its cytotoxicity against DU145 prostate cancer cells, as was the underlying mechanisms by which WYC02-9 might induce DNA damage and apoptotic cell death through reactive oxygen species (ROS). WYC02-9 inhibited the cell growth of three prostate cancer cell lines, especially DU145 cells. In DU145 cells, WYC02-9 increased the generation of intracellular ROS, followed by induction of DNA damage and activation of the ATM-p53-H2A.X pathway and checkpoint-related signals Chk1/Chk2, which led to increased numbers of cells in the S and G2/M phases of the cell cycle. Furthermore, WYC02-9 induced apoptotic cell death through mitochondrial membrane potential decrease and activation of caspase-9, caspase-3, and PARP. The above effects were all prevented by the ROS scavenger N-acetylcysteine. Administration of WYC02-9 in a nude mouse DU145 xenograft model further identified the anti-cancer activity of WYC02-9. These findings therefore suggest that WYC02-9-induced DNA damage and mitochondria-dependent cell apoptosis in DU145 cells are mediated via ROS generation.

RESUMO

BACKGROUND: This retrospective, case-control study was designed to find side effects of hypoparathyroidism after total parathyroidectomy plus autotransplantation. METHODS: After successful total parathyroidectomy plus autotransplantation for symptomatic secondary hyperparathyroidism, 19 patients who had intact parathyroid hormone (iPTH) levels <10 pg/ml during the follow-up period of 1 year and 38 patients, who had levels >10 pg/ml, were enrolled as the hypoparathyroid and nonhypoparathyroid groups. Data were collected on etiology, symptoms, serum levels of calcium, phosphate, alkaline phosphatase (Alk-ptase), iPTH, and bone mineral density (BMD) at different sites. Then, 1 week, 3 months, and 1 year after surgery, serum levels of calcium, phosphate, Alk-ptase, and iPTH were measured again. Three months later, symptoms were recorded. One year after surgery, the BMD at different sites was measured again. Patients' daily requirements of calcium carbonate and vitamin D3 were recorded at the mean follow-up of 24 months. RESULTS: Calcium, phosphate, and iPTH levels decreased significantly 1 week, 3 months, and 1 year after surgery, and Alk-ptase levels increased at 1 week and then decreased significantly 3 months and 1 year after surgery. Symptoms improved significantly 3 months after surgery. The BMD of different sites increased significantly at 1 year. There were no differences between the two groups regarding changes of symptoms, BMD, and calcium, phosphate, and Alk-ptase levels. Hypoparathyroid patients required significantly more calcium carbonate and vitamin D3 than nonhypoparathyroid patients did (P = 0.002). CONCLUSIONS: Even though hypoparathyroid patients require more calcium carbonate and vitamin D3 than nonhypoparathyroid patients do, they do not have any side effects.

RESUMO

A 48-year-old woman presented with 3 days of hoarseness and 1 week of unrelenting back pain. Her medical history was remarkable for an esophageal operation 20 years before to repair damage from caustic esophagitis. The computed tomography scan identified a large esophageal mucocele. Resection of the remaining intrathoracic esophagus was required for complete resolution of the patient's symptoms.

RESUMO

BACKGROUND: We studied bone mineral density (BMD) after total parathyroidectomy plus autotransplantation (TPTD plus AT) followed by kidney transplantation in patients with symptomatic secondary hyperparathyroidism. METHODS: We recruited 43 patients who were operated on with TPTD plus AT for this study. Group A (n=36) patients continued hemodialysis regularly thereafter; Group B (n=7) patients were followed by cadaveric kidney transplantation. In group A, serum calcium, phosphorus, alkaline phosphatase (Alk-ptase) and intact parathyroid hormone (iPTH) levels were measured at baseline, 1 week, and in the late follow-up period. In group B, serum calcium, phosphorus, Alk-ptase and iPTH levels were measured at baseline, 1 week after parathyroidectomy, and in the late follow-up period after kidney transplantation. The BMD of lumbar spine, femur, ulna and radius was measured with dual x-ray absorptiometry at baseline, and again at 1 year in group A and at 1 year after kidney transplantation in group B. RESULTS: At 1 week after TPTD plus AT, calcium, phosphorus, and iPTH levels decreased significantly but Alk-ptase did not. In the late follow up period calcium, phosphorus, Alk-ptase and iPTH levels decreased significantly compared with those at baseline. In group A, the BMD of lumbar spine, femur, ulna and radius increased significantly 1 year later. In group B, the BMD of femur, ulna and radius increased significantly 1 year after kidney transplantation, but the BMD of lumbar spine did not. CONCLUSION: TPTD plus AT followed by kidney transplantation performed for symptomatic secondary hyperparathyroidism can improve the BMD of femur, ulna, and radius.

RESUMO

BACKGROUND: Cognitive impairment was frequently reported in uremic patients with dialysis, but improvements of cognition after parathyroidectomy for symptomatic secondary hyperparathyroidism have never been reported before. METHODS: Thirty-nine patients, who were successfully operated on with total parathyroidectomy plus autotransplantation were enrolled. Twenty-three dialysis patients, age >50 years, who had a serum level of intact parathyroid hormone (iPTH) greater than 650 pg/ml, and who did not undergo parathyroidectomy were selected as the control group. The mini-mental state examination (MMSE) and the clinical dementia rating (CDR) test were administered to all patients. Before the operation, educational level, symptoms of bone pain, skin itching, general weakness and insomnia were recorded and serum levels of calcium, phosphorus, alkaline phosphatase (Alk-ptase), iPTH, aluminum, and hemoglobin were measured in the study and control groups. At 12-week postoperatively, serum levels of calcium, phosphorus, Alk-ptase, iPTH, and aluminum were measured again and at 16-week postoperatively, the MMSE and the CDR test were administered again. In the control group, both MMSE and CDR test were administered again after the period or 16-week. RESULTS: Serum calcium level was only significant difference (p = 0.002), whereas clinical symptoms, gender, etiologies of secondary hyperparathyroidism, duration of dialysis, educational level, age, and serum levels of phosphorus, Alk-ptase, iPTH, aluminum, and hemoglobin were not significantly different between the two groups. The educational level was the only factor affecting MMSE scores (p = 0.003). In the study group, at 12-week postoperatively, symptoms improved significantly, serum levels of calcium, phosphorus, Alk-ptase, iPTH, and aluminum decreased significantly, and at 16-week postoperatively, MMSE scores increased from 25 +/- 5 (mean +/- SD) to 26 +/- 5 (p < 0.001) and CDR scales decreased significantly (p < 0.001). Neither MMSE scores nor CDR scales of the control group changed significantly after the 16-week period. CONCLUSION: Parathyroidectomy for symptomatic secondary hyperparathyroidism can improve cognition.

RESUMO

Fibrosing mediastinitis is a chronic disease process with a spectrum of etiology. We report a 51-year-old female who underwent incision and drainage procedure in the neck for deep neck and mediastinal abscess. Five years later she developed fibrosing mediastinitis. This lesion infiltrated from neck base into the upper mediastinum with tracheal compression and vessel encasement. She had resection of the lesion which proved to be a ruptured bronchogenic cyst with chronic inflammation. This rare case illustrates the importance of including inflammatory bronchogenic cyst in the etiology of deep neck abscess formation. And we further find a ruptured bronchogenic cyst with chronic inflammation as an etiology of fibrosing mediastinitis.

RESUMO

Intravenous (i.v.) calcium chloride is usually given to treat symptomatic hypocalcemia; however, the extravasation of calcium solution may cause soft tissue and skin necrosis. After parathyroidectomy and autotransplantation for secondary hyperparathyroidism associated with end-stage renal failure, i.v. calcium infusion is often necessary to treat severe postoperative hypocalcemia. We reviewed 371 patients who underwent parathyroidectomy for secondary hyperparathyroidism between January 2000 and June 2005, 96 of whom received i.v. calcium postoperatively for symptomatic hypocalcemia. We report the cases of three (3%) of our own patients and of one patient referred to our hospital, who suffered skin necrosis after i.v. calcium solution administration. These reports show that i.v. calcium should be administered into large veins, or via a central line, and diluted in an appropriate volume of solution. Moreover, the calcium solution infusion should be ceased if the patient complains of tenderness over the injection site. If skin necrosis develops, we suggest early debridement and a simple split thickness skin graft to repair the skin defect. We report our experience to remind surgeons of the danger of calcium chloride injection and to discuss ways of preventing and treating this complication.

RESUMO

OBJECTIVE: Large midline abdominal wall defects are continuously a challenge for reconstructive surgeons. Adequate skin coverage and fascia repair of the abdominal wall is necessary for achieving acceptable results. The purpose of this paper is to present a new approach to abdominal wall reconstruction using a free vascularized composite anterolateral thigh (ALT) flap with fascia lata. METHODS: Seven patients with large full-thickness abdominal wall defects were successfully reconstructed by means of a composite ALT flap combined with vascularized fascia lata. The size of the skin islands ranged from 20 to 32 cm in length and 10 to 22 cm in width, and the vascularized fascia lata sheath measured 14 to 28 cm and 8 to 18 cm, respectively. Functional outcome of the abdominal wall strength and donor thigh morbidity were investigated by using a Cybex kinetic dynamometer. RESULTS: All flaps survived. No postoperative ventral hernia occurred except for one mild inguinal incision hernia. Subjectively there were no significant donor site problems. Objective assessment was performed in 4 patients 2 years postoperatively. In the reconstructed abdomen, isokinetic concentric and eccentric measurements of extension/flexion ratios of the abdominal wall strength showed no apparent decrease compared with other references. Functional evaluation of quadriceps femoris muscle contraction forces after free ALT composite flap harvest showed an averaged deficit of 30% as compared with the contralateral legs. However, no difficulties in daily ambulating were reported by the patients. CONCLUSION: The free composite ALT myocutaneous flap with vascularized fascia lata provides an alternative option for a stable repair in complex abdominal wall defects.
