ABSTRACT
@#Objective To investigate the prognostic survival status and influence factors for surgical treatment of esophageal squamous cell carcinoma (ESCC) in pathological stage T1b (pT1b). Methods The patients with ESCC in pT1b undergoing Ivor-Lewis or McKeown esophagectomy in Lanzhou University Second Hospital from 2012 to 2015 were collected, including 78 males (78.3%) and 17 females (21.7%) with an average age of 61.4±7.4 years. Results The most common postoperative complications were pneumonia (15.8%), anastomotic leakage (12.6%) and arrhythmia (8.4%). Ninety-three (97.9%) patients underwent R0 resection, with an average number of lymph node dissections of 14.4±5.6. The rate of lymph node metastasis was 22.1%, and the incidence of lymph vessel invasion was 13.7%. The median follow-up time was 60.4 months, during which 25 patients died and 27 patients relapsed. The overall survival rate at 3 years was 86.3%, and at 5 years was 72.7%. Multivariate Cox regression analysis showed that lymph node metastasis (P=0.012, HR=2.60, 95%CI 1.23-5.50) and lympovascular invasion (P=0.014, HR=2.73, 95%CI 1.22-6.09) were independent risk factors for overall survival of pT1b ESCC. Conclusion Esophagectomy via right chest approach combined with two-fields lymphadenectomy is safe and feasible for patients with pT1b ESCC. The progress of pT1b ESCC with lymph node metastasis or lymphovascular invasion is relatively poor.
ABSTRACT
RESUMEN Fundamentación: En la provincia Sancti Spíritus no se reportan estudios sobre la supervivencia de pacientes con cáncer de pulmón sometidos a cirugía de resección con linfoadenectomía por muestreo. Objetivo: Evaluar la supervivencia de los pacientes con cáncer de pulmón sometidos a cirugía de resección pulmonar y linfadenectomía por muestreo. Metodología: Se realizó una investigación retrospectiva en el Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus, desde el 1 de enero del 1996 al 31 de diciembre del 2007. Fueron incluidos 48 pacientes a los que se les realizó cirugía de resección pulmonar con linfadenectomía por muestreo. Como variable principal fue considerada la supervivencia global a los 5 y 10 años. Otras variables fueron: edad, sexo, clasificación histológica y estadio patológico del tumor primario. Resultados: Predominaron los pacientes del sexo masculino, los mayores de 50 años y con estadio patológico IB. La estirpe histológica predominante fue el carcinoma epidermoide. La mediana de supervivencia fue superior para los estadios tempranos. La mayor supervivencia a los 5 años correspondió a los estadios IA y IIA. A los 10 años no hubo diferencias en la supervivencia de los pacientes. Conclusiones: La mayor supervivencia a los 5 años de los pacientes sometidos a cirugía de resección pulmonar y linfadenectomía por muestreo correspondió a los que se encontraban en estadios con menor extensión de la enfermedad. Entre los 5 y 10 años después de la cirugía hubo una estabilización en la sobrevida de todos los pacientes, indistintamente del estadio patológico inicial.
ABSTRACT Background: In Sancti Spiritus province there are no reports on the survival of patients with lung cancer undergoing resection surgery with lymphadenectomy by sampling. Objective: To evaluate the survival of patients with lung cancer undergoing lung resection surgery and lymphadenectomy by sampling. Methodology: A retrospective investigation was conducted at Camilo Cienfuegos General Provincial Hospital of Sancti Spíritus, from January 1, 1996 to December 31, 2007. They were included 48 patients who underwent lung resection surgery with lymphadenectomy by sampling. The main variable was considered overall survival at 5 and 10 years. Other variables were: age, sex, histological classification and pathological stage of the primary tumor. Results: Male patients, those older than 50 years and with pathological stage IB predominated. The predominant histological line was squamous cell carcinoma. The median survival was higher for the early stages. The greatest survival at 5 years corresponded to stages IA and IIA. At 10 years there were no differences in patient survival. Conclusions: The greatest survival at 5 years of patients undergoing lung resection surgery and lymphadenectomy by sampling corresponded to those who were in stages with less extension of the disease. Between 5 and 10 years after surgery there was stabilization in the survival of all patients, regardless of the initial pathological stage.

Objective To evaluate the clinical and pathological features of patients with prostate cancer who were diagnosed by single positive core biopsy and treated by radical prostatectomy (RP).Methods Between July 2012 and June 2016,164 patients with prostate cancer diagnosed by single positive core biopsy underwent RP.The mean age was 66.3 years old (ranged 41-82 years old),and the mean PSA level was 12.3 ng/ml (ranged 0.6-59.5 ng/ml).The biopsy Gleason score showed 6 scores in 113 cases,3 + 4 =7 scores in 21 cases,4 + 3 =7 scores in 18 cases,≥8 scores in 12 cases.Clinical stage was cT1 in 71 cases,cT2 in 92 cases,and cT3 in 1 case.The patients were divided into subgroups according to age,preoperative PSA level,biopsy Gleason score and clinical stage,and the pathological results were compared among these subgroups.Results Of the 164 patients,67 cases had Gleason score ≤ 6,52 cases Gleason score 3 + 4 =7,24 case Gleason score 4 + 3 =7,and 11 cases Gleason score ≥ 8.Ten patients had pT0 disease according to the RP specimen,3 had extraprostatic extensions,5 had seminal vesicle invasions,and 24 had positive surgical margins.Compared to the biopsy,the Gleason score of RP specimens was higher in 53 cases,concordant in 77 cases,and lower in 24 cases.There was no significant difference in the postoperative pathological features between the age group ＜ 70 years and the group ≥ 70 years.Compared with PSA ＜ 10 ng/ml,the likelihood of postoperative Gleason score ＞ 7 was significantly increased in PSA ≥10 ng/ml group [41.4％ (36/87) vs.66.2％ (51/77),P＜0.05].When the biopsy Gleason score was divided into four groups (6,3 + 4 =7,4 + 3 =7,≥ 8),there were significant differences in postoperative pathological stages among the four groups (P ＜ 0.05),and the patients with biopsy Gleason score 6 were more likely to have no residual cancer (stage T0) when compared with other Gleason scores [8.8％ (10/113) vs.0,P =0.09].The probability of no residual cancer in clinical T1 stage patients was significantly higher than that in T2 stage [11.3％ (8/71) vs.2.8％ (2/92),P =0.02],while the probability of Gleason score upgrading was significantly lower [23.9％ (17/71) vs.39.1％ (36/92),P ＜ 0.05].Conclusions Most single core prostate cancer have clinically significant disease.The treatment plan must be evaluated individually for patients with single core prostate cancer.
ABSTRACT
Objective To evaluate the role of PSA density with prostate volume determined by MR images in the prediction of extraprostatic extension in patients with clinically organ-confined prostate cancer.Method A total of 71 patients with clinically organ-confined prostate cancer who underwent radical prostatectomy from January 2009 to December 2013 were included in the study.MRI PSAD,preoperative total serum PSA (tPSA),free PSA/total PSA (fPSA/tPSA),biopsy Gleason score,prostate volume,age,body mass index in patients with extraprostatic extension were compared with those in patients with organ-confined disease.The receiver operating characteristic (ROC) curve was used to analyze the performance of each of the above parameters to predict the extraprostatic extension.Multivariate logistic regression analysis was used to select the independent influencing factors for extraprostatic extension.Results Pathologic examination revealed 32 patients were positive for extraprostatic extension and 39 paticnts had organ-confined disease.MRI PSAD(P ＜ 0.001),tPSA (P ＜ 0.00l) and biopsy Gleason score levels (P =0.006) were higher in patients with extraprostatic extension than that in patients with organ-confined disease,and prostate volume was lower(P =0.009).MRI PSAD showed the largest area under ROC curve (AUC) among those parameter(AUC =0.852,P ＜ 0.001),and tPSA was the second (AUC =0.764).Multivariate logistic regression analyses showed that MRI PSAD was an independent predictor of extraprostatic extension.Conclusions MRI PSAD was better than tPSA in predicting pathological stage of extraprostatic extension.The value of PSAD should not be ignored in the prediction of pathological stage.
ABSTRACT
Objective To investigate the rationality and prognostic value of the Criteria for clinical staging of esophageal cancer treated by non-surgical methods (Draft) by comparison with the criteria for postoperative pathological staging.Methods A retrospective analysis was performed on the clinical data of 162 patients with esophageal cancer who underwent radical resection at the Second Hospital of Soochow University from December 2008 to July 2012.Preoperative clinical staging and postoperative pathological staging were performed,and the Kappa statistic was used to evaluate the agreement between the two staging systems.The Kaplan-Meier method was used to calculate overall survival (OS) rates,and the log-rank test was used for survival difference analysis and univariate analysis.Results The coincidence rates of T,N,and TNM stages were 67.9％,57.4％,and 67.9％,respectively,and the agreements were moderate,poor,and moderate,with Kappa values of 0.544,0.302,and 0.509.The follow-up rate was 93.2％.The 1-,2-,and 3-year sample sizes were 127,66 and 27,respectively.The 1-,2-,and 3-year OS rates were 82.6％,56.2％,and 37.7％,respectively.There were no significant differences in OS between patients with preoperative T1 and T2 stages and between patients with preoperative N0 and N1 stages (P =0.086,0.101),but significant differences were observed between patients with different T stages,N stages,or TNM stages (P =0.000-0.028).This was in line with the prognostic results based on the postoperative pathological staging.Conclusions The clinical staging criteria (draft) have moderate agreement with the criteria for postoperative pathological staging and have good prognostic value,but they require further refinement and improvement.
ABSTRACT
Objective To explore the clinicopathology characteristics of endometrial adenocarcinoma and non-endometrial adenocarcinoma.Methods The clinical data of 306 patients with endometrioid cancer were analyzed retrospectively.Results The patients with endometrial adenocarcinoma accounted for 90％ of all patients,and the patients with non-endometrial adenocarcinoma accounted for 10％.Compared with the patients with endometrial adenocarcinoma,the average age of the patients with non-endometrial adenocarcinoma was older[(59.32 ± 7.77)years],the constitution ratio of postmenopausal patients was higher(90％),the clinicopathologic stage was later(P =0.000),the grade of histology was higher(P =0.000),the myometrial invasion was deeper(P =0.014).The patients with nonendometrial adenocarcinoma were prone to occur lymph metastasis(P =0.006),and the recurrence rate was higher(P =0.000).Conclusion There is significant defference between endometrial adenocarcinoma and non-endometrial adenocarcinoma,the patients with non-endometrial adenocarcinoma has poor pronosis,and we should pay more attention to it.
ABSTRACT
Objective To investigate the clinical characteristics and prognosis of young patients with endometrial cancer.Methods Thirty cases with endometrial cancer were selected as our observed group (age less than 40 years old).Forty cases with endometrial cancer were selected as control group and their age were over 40 years old.The information about clinical characteristics,diagnosis,treatment and prognosis of patients in two groups were collected.Results The rates of primary infertility and less than 3 times of pregnancy in observed group were 30.0％ (9/30),56.7％ (17/30) respectively,higher than that in control group (5.0％(2/40) or 30.0％ (12/40)).The differences were statistically significant (x2 =6.183,5.372 respectively,P ＜ 0.05).The positive rate of estrogen receptor(ER) and progesterone receptor(PR) expression were 93.3％ (28/30) and 86.7％ (26/30) in observed group,higher than that in control(42.5％ (17/40),52.5％ (21/40)respectively).The differences were statistically significant (x2 =5.951,4.721 respectively,P ＜ 0.05).Two groups of patients were statistically significant differences in pathological stage,the pathological type of observed group was mainly stage Ⅰ (76.7％ (23/30)),higher than that of control group (47.5 (19/40),and the difference was statistically significant (x2 =5.464,P ＜ 0.05).There was statistically significant difference between the observed and control group on Cervical infiltration and lymph node metastasis(x2 =5.464,1.018respectively,P ＜ 0.05).Conclusion The infeaility and less than 3 times of pregnancy may be the risk factors of younger endometrial cancer and the pathological type of observed group was mainly stage Ⅰ.However the prognosis is similar between the young and the old patients.
ABSTRACT
PURPOSE: To evaluate the outcomes and prognostic factors of postoperative radiotherapy (PORT) for patients with pathological stage III non-small-cell lung cancer (NSCLC) at a single institution. MATERIALS AND METHODS: From 2000 to 2007, 88 patients diagnosed as having pathologic stage III NSCLC after curative resection were treated with PORT. There were 80 patients with pathologic stage IIIA and eight patients with pathologic stage IIIB in the AJCC 6th staging system. The majority of patients (n=83) had pathologic N2 disease, and 56 patients had single station mediastinal LN metastasis. PORT was administered using conventional technique (n=76) or three-dimensional conformal technique (n=12). The median radiation dose was 54 Gy (range, 30.6 to 63 Gy). Thirty-six patients received chemotherapy. Radiation pneumonitis was graded by the Radiation Therapy Oncology Group system, and other treatment-related toxicities were assessed by CTCAE v 3.0. RESULTS: Median survival was 54 months (range, 26 to 77 months). The 5-year overall survival (OS) and disease free survival (DFS) rates were 45% and 38%, respectively. The number of metastatic lymph nodes was associated with overall survival (hazard ratio, 1.037; p-value=0.040). The 5-year locoregional recurrence free survival (LRFS) and distant metastasis free survival (DMFS) rates were 88% and 48%, respectively. Multiple stations of mediastinal lymph node metastasis was associated with decreased DFS and DMFS rates (p-value=0.0014 and 0.0044, respectively). Fifty-one relapses occurred at the following sites: 10 loco-regional, 41 distant metastasis. Grade 2 radiation pneumonitis was seen in three patients, and symptoms were well tolerated with anti-tussive medication. Grade 2 radiation esophagitis was seen in 11 patients. There were no grade 3 or more severe complications associated with PORT. CONCLUSION: Our retrospective data show that PORT for pathological stage III NSCLC is a safe and feasible treatment and could improve loco-regional control. The number of metastatic lymph nodes and stations of mediastinal lymph node metastasis were analyzed as prognostic factors. Furthermore, efforts are needed to reduce distant metastasis, which is a major failure pattern of advanced stage NSCLC.
