Muertes por cáncer en "Jerez de los Caballeros"(Badajoz, España) en el s. XIX: Un estudio histórico observacional de centro único / Deaths from cancer in "Jerez de losCaballeros" (Badajoz, Spain) in the 19th century. XIX. A single-center, historical observational study

Introducción:El cáncer representa un extraordinario problema para la Salud Pública mundial, suponiendo la primera causa de mortalidad global. El cáncer de pulmón es el más frecuente. El número de defunciones se ha ordenado de acuerdo a la Clasificación de Bertillon. El objetivo del estudio fue analizar las causas de mortalidad por cáncer; determinar que grupos de edad presentan más muertes y que estaciones; calcular las tasas de mortalidad.Materiales y métodos:mediante la lectura de los Libros de Defunción del Archivo Parroquial de la ciudad (APJC), se han obtenido 26.203 difuntos, 18.538 de los cuales tienen anotado el motivo de su muerte, los cuales son utilizados para su análisis posterior.Resultados:Se registraron 182 defuncionespor cáncer(1% del total), la gran mayoría adultos, 165 (90.7%), siendo las mujeres casi el doble, 121 (66.5%). La mayor mortalidad se da entre los 45 y los 74 años, 122 difuntos (67.0%). El cáncer más frecuente es el del apartado de otros órganos, con 50 defunciones (40.6%). El mes con más muertos es marzo.las papeletas de defunción solían presentar errores ortográficos o de transcripción. Estudios similares en otras poblaciones arrojan cifras dispares según el periodo analizado y la cifra de muertos. Existe una estrecha relación entre cáncer y edad.Conclusión:El cáncer de otros órganos es el más numeroso. La mortalidad difiere entre las distintas poblaciones comparadas. El número de difuntos es muy inferior al actual, debido a la falta de medios diagnósticos y conocimientos de la época y la posible existencia de un subregistro

Introduction: Cancer represents an extraordinary problem for Global Public Health and is the leading cause of global mortality. Lung cancer is the most common cancer. The number of deaths was ordered according to the Bertillon Classification. The objective of the study was to analyze the causes of mortality due to cancer, determine which age groups have the most deaths and which seasons, and calculate mortality rates.Materials and methods: By reading the Death Books of the city's Parish Archive (APJC), 26,203 deceased persons were obtained, 18,538 of whom were diagnosed with COVID-19, and these individuals were used for subsequent analysis.Results: A total of 182deaths due to cancer were recorded (1% of the total);the vast majority wereadults (165,90.7%), with nearlytwice as manywomen (121, 66.5%). The highest mortal-ity occurredbetween 45 and 74 years of age, with 122 deaths (67.0%). The most common cancer wasthat of other organs, accounting for50 deaths (40.6%). The month with the most deaths wasMarch. Death certificates often had spelling or transcription errors. Similar studies in other populations show different figures depending on the period analyzed and the number of deaths. There is a close relationship between cancer incidence and age.Conclusion: Cancer of other organs is the most common cancer. Mortality differs between the different populations compared. The number of deaths is much lower than the current numberdue to the lack of diagnostic methods, knowledge of the time,and the possibility of underrecording

The current role of surgery in the treatment of cardiac metastases from malignant melanoma: an educational presentation

Abstract A 71 year-old male with a history of multiple excisions of an initial Clark's level V melanoma of the breast followed by combined radiation and interferon treatment, as well as a recurrence, 3 years later, of a BRAF-positive tumor of the shoulder, with subsequent therapy with dabrafenib and trametinib, presented again with progressive intracardiac masses causing significant right ventricular outflow obstruction. Additionally, the patient complained of dyspnea and fatigue on exertion, thus he was scheduled for surgical resection.

Relationship between BRAFV600E mutation and metastasis after thyroidectomy in papillary thyroid carcinoma with different recurrence risk stratification / 中华核医学与分子影像杂志

Objective@#To investigate the relationship between V-raf murine sarcoma viral oncogene homologue B1 (BRAF)V600E mutation and metastasis after thyroidectomy in papillary thyroid carcinoma (PTC) with different recurrence risk stratification.@*Methods@#From March 2014 to September 2017, 134 PTC patients (45 males, 89 females; age: 16-72 years) who underwent 131I treatment in the Department of Nuclear Medicine of Liaocheng People′s Hospital and had undergone BRAFV600E mutation detection were retrospectively analyzed. The recurrence risk during surgery was divided into 3 levels: low-, medium- and high-risk. Each recurrence risk group was divided into 3 subgroups according to the postoperative follow-up results: non-metastasis group, cervical lymph node metastasis group and pulmonary metastasis group. BRAFV600E mutation rates in different groups were compared (χ2 test).@*Results@#The BRAFV600E mutation rate was 55.22%(74/134) in 134 PTC patients. The mutation rates were not significantly different in the 3 metastasis subgroups for low-risk patients (n=46; χ2=2.39, P>0.05). In medium-risk patients (n=47), the mutation rate in neck lymph node metastasis group (16/19) was higher than that in pulmonary metastasis group (3/8) and non-metastasis group (25.00%, 5/20; χ2 values: 5.89 and 13.75, both P<0.05), while there was no difference between pulmonary metastasis group and non-metastasis group (χ2=0.44, P>0.05). In high risk patients (n=41), the mutation rate in neck lymph node metastasis group (85.00%, 17/20) was higher than that in the pulmonary metastasis group (5/13) and non-metastasis group (1/8; χ2 values: 7.68 and 13.08, both P<0.01), while there was no difference between pulmonary metastasis group and non-metastasis group (χ2=1.64, P>0.05).@*Conclusion@#The BRAFV600E mutation is closely related to neck lymph node metastasis after operation in middle- and high-risk patients with PTC, but it does not significantly increase the probabilities of neck lymph node metastasis in low-risk patients and pulmonary metastasis in low-, medium- and high-risk patients.

Abdominal lymph node recurrence after radical surgery in patients with middle thoracic esophageal squamous cell carcinoma:risk factors and guidance for postoperative radiotherapy / 中华放射肿瘤学杂志

Objective To analyze the risk factors for abdominal lymph node recurrence after radical surgery in patients with middle thoracic esophageal squamous cell carcinoma (TE-SCC),and to design the target volume for postoperative radiotherapy based on the results.Methods A retrospective study was performed among 913 patients with middle TE-SCC undergoing radical surgery who were admitted to our hospital from 2007 to 2012.Influencing factors were analyzed for abdominal lymph node recurrence after treatment.The efficacy was compared between different treatment methods in the high-risk population.Comparison of categorical data was made by chi-square test.The overall survival rates (OS) were calculated by the Kaplan-Meier method and analyzed by the univariate log-rank analysis.The influencing factors for abdominal lymph node recurrence were analyzed by the multivariate logistic regression equation.Results After treatment,37 patients had abdominal lymph node recurrence,yielding a recurrence rate of 4.1％.A total of 53 recurrent sites were found.The univariate analysis showed that no/low differentiation,pT3+4 stage,no less than 3 positive postoperative lymph nodes,and positive postoperative abdominal lymph nodes were influencing factors for abdominal lymph node recurrence (P =0.032,0.001,0.009,0.000).The multivariate regression analysis showed that pathological T staging and positive postoperative abdominal lymph nodes were influencing factors for abdominal lymph node recurrence (P=0.011,0.000).For patients with pT3+4 stage disease and positive postoperative abdominal lymph nodes,postoperative radiotherapy improved OS and local control rates but failed to reduce the distant metastasis-free rate.Conclusions T staging and positive postoperative abdominal lymph nodes are important risk factors for abdominal lymph node recurrence after radical surgery in patients with middle TE-SCC.Postoperative adjuvant therapy is recommended for patients with pT3+4 stage disease and positive postoperative abdominal lymph nodes.

ATYPICAL STERNAL PAIN IN A BREAST CANCER PATIENT MIMICKING ACUTE MYOCARDIAL INFARCTION / Dor esternal atípica no câncer de mama mimetizando infarto agudo do miocárdio

Radiation therapy on the left side of the chest, some chemotherapy drugs, and trastuzumab raise the risk of cardiac events. Acute chest pain associated with breast cancer is not common, but it is possible. Electrocardiogram, which can result normal in up to 80% of cases of infarction, and serial dosing of myocardial necrosis markers are fundamental for differential diagnosis. Total creatine kinase (CK), creatine kinase-MB fraction (CK-MB), and troponins are frequently used. We present the case of a patient with atypical chest pain associated with elevation of CK and CK-MB, whose evolution and complementary exams showed to be a thoracic tumor recurrence. We discuss the use of these markers for acute chest pain; possible differential diagnoses, the use of CKMB relative index and, particularly, the presence of macro CK in some breast cancer patients ­ which in the case herein presented was a marker of tumor progression.

A radioterapia do lado esquerdo do tórax, alguns quimioterápicos e o trastuzumabe elevam o risco de eventos cardíacos. A dor torácica aguda associada ao câncer de mama não é um evento frequente, mas é possível. No diagnóstico diferencial, faz-se necessário o eletrocardiograma, que pode ser normal em até 80% dos infartos, e a dosagem seriada de marcadores de necrose miocárdica, sendo frequentemente utilizados a creatinoquinase (CK) total, a creatinnoquinase fração MB (CK-MB) e as troponinas. Apresentamos o caso de uma paciente com dor torácica atípica associada à elevação sérica da CK e da CK-MB, sendo que a evolução e os exames complementares mostraram tratar-se de uma recorrência tumoral torácica. Discutem-se a utilização desses marcadores na dor torácica aguda, os diagnósticos diferenciais possíveis, a utilização do índice relativo CK-MB e, em especial, as macro CK presentes em algumas portadoras de câncer de mama, o que, nessa paciente, foi um marcador de progressão tumoral.

Efficacy evaluation of rescue treatment for 218 patients with recurrent esophageal cancer after radical resection / 中华放射肿瘤学杂志

Objective To evaluate the efficacy of rescue treatment for recurrent esophageal cancer after radical esophagectomy, and to provide insights into the development of comprehensive treatment for esophageal cancer.Methods The clinical data of 218 patients who were confirmed with recurrent metastatic esophageal cancer after R0 resection and received rescue treatment in our hospital from 2004 to 2014 were retrospectively reviewed.The survival rate was determined by the Kaplan-Meier method.Univariate and multivariate prognostic analyses were performed using the log-rank test and Cox proportional hazards model, respectively.Results The median post-recurrence follow-up time was 53 months.The 1-and 3-year overall survival (OS) rates after recurrence were 57.2% and 24.4%, respectively.Among the 163 patients with local recurrence, the 1-and 3-year OS rates were 70% and 42% for patients treated with chemoradiotherapy (n=40), 55% and 24% for those with radiotherapy alone (n=106), and 23% and 8% for those with supportive therapy (n=13)(chemoradiotherapy vs.radiotherapy alone P=0.045, radiotherapy alone vs.supportive therapy P=0.004;none of the patients who were treated with chemotherapy alone survived for one year or more).Univariate analysis showed that N staging, TNM staging, and post-recurrence rescue treatment regimen were independent prognostic factors for esophageal cancer (all P=0.001).On the other hand, multivariate analysis indicated that only rescue treatment regimen was the independent prognostic factor for esophageal cancer (P=0.013).Conclusions Rescue chemoradiotherapy or radiotherapy alone can bring significant survival benefits for patients with recurrent and metastatic, especially locally recurrent, esophageal cancer following radical esophagectomy.

Clinical efficacy of radiotherapy in treatment of recurrent lesions at vaginal cuff after hysterectomy for cervical cancer / 中华放射肿瘤学杂志

Objective To analyze the long-term efficacy and adverse effects of radiotherapy in the treatment of recurrent lesions at the vaginal cuff after hysterectomy for cervical cancer, and to investigate prognostic factors.Methods A total of 105 patients who were admitted to our hospital due to recurrent lesions at the vaginal cuff after hysterectomy for cervical cancer from January 2005 to July 2011 were enrolled in this study and divided into group A (6-12 months), group B (12-24 months), and group C (≥24 months) according to the time to recurrence.All patients received radiotherapy and only 96 patients also received concurrent chemotherapy.The long-term outcomes and adverse events were compared between the three groups, and the prognostic factors were analyzed.Survival curves were analyzed by the Kaplan-Meier method.Results The follow-up rate was 98.1%.The response rates of group A, B, and C were 60%, 82%, and 86%, respectively.The 3-and 5-year survival rates for all patients were 58.1% and 31.4%, respectively.The median survival time for all patients was 42 months.Group C had a significantly longer median survival time than group A (P=0.010).The patients with a maximum tumor diameter of<4 cm had a significantly better treatment outcome than those with a maximum tumor diameter of ≥4 cm (P=0.000).There was a significant difference in median survival time between the patients with recurrent lesions limited to the vaginal cuff and those with recurrent lesions beyond the vaginal cuff (47 months vs.32 months, P=0.005).Conclusions For patients with recurrent lesions at the vaginal cuff after hysterectomy for cervical cancer, radiotherapy is a salvage treatment and has significant clinical efficacy.The treatment outcome and prognosis are related to time to recurrence, tumor size, and the extent of recurrent lesions.

An analysis of prognostic factors for stage ⅢA (N2) non-small cell lung cancer after complete resection / 中华放射肿瘤学杂志

Objective To investigate the factors associated with postoperative metastasis, recurrence, and survival in patients with stage ⅢA ( N2 ) non?small cell lung cancer ( NSCLC ) , and to provide an objective basis for postoperative radiotherapy in patients. Methods Clinical data were collected from 199 patients who underwent complete resection and were diagnosed with stage ⅢA ( N2 ) NSCLC after surgery in our hospital from 2009 to 2013. The Cox regression model was used for the multivariate analyses of metastasis and recurrence. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. Results In the 199 patients, 173 had complete follow?up data. The 1?and 2?year metastasis, recurrence, and survival rates were 38?7%/52?6%, 27?8%/39?1%, and 92?5%/51?4%, respectively. The multivariate analysis showed that pathological type and two positive indices among preoperative CEA/CY211/SCC were two risk factors for metastasis ( P=0?013,0?014) . Positive lymph node number, metastatic lymph node number, lymph node metastasis rate, and two positive indices among preoperative CEA/CY211/SCC were risk factors for recurrence ( P=0?046,0?004,0?028,0?001) . All the above indices were risk factors for low survival rates ( P= 0?013 , 0?011 , 0?002,0?026 ) . Conclusions Patients with stage ⅢA ( N2 ) NSCLC who have positive lymph nodes, lymph node metastases, and two positive indices among preoperative CEA/CY211/SCC may benefit from postoperative radiotherapy.

Salvage therapy for postoperative recurrence or metastasis in stage T3 N0 M0 thoracic esophageal squamous cell carcinoma / 中华放射肿瘤学杂志

Objective To analyze the efficacy of salvage therapy for postoperative recurrence or metastasis in patients with stage T3 N0 M0 thoracic esophageal squamous cell carcinoma ( ESCC ) and its influencing factors. Methods A retrospective analysis was performed in 108 patients with postoperative recurrence or metastasis in stage T3 N0 M0 thoracic ESCC who were admitted to our hospital from 2008 to 2009. In those patients, 59 had locoregional recurrence ( LR) , 26 distant metastasis ( DM) , and 23 both LR and DM. After recurrence, 53 patients received supportive therapy, 32 salvage radiotherapy, 9 chemotherapy, and 14 chemoradiotherapy. The overall survival ( OS) rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The univariate and multivariate prognostic analyses were performed using the log?rank test and the Cox regression model, respectively. Results The follow?up rate was 100%. In all patients, the 1?, 3?, and 4?year OS rates were 29?9%, 16?5%, and 14?4%, respectively;the median OS time was 6 months. The univariate analysis showed that recurrence pattern and salvage therapy were associated with OS after recurrence ( P=0?017;P=0?000) . The multivariate analysis showed that salvage therapy was the only independent factor for OS after recurrence ( P=0?000) . Compared with supportive therapy, the risk of death after chemotherapy, radiotherapy, or chemoradiotherapy was reduced by 76?7%, 76?7%, and 86?1%, respectively. Conclusions The treatment outcomes are poor in patients with postoperative recurrence of stage T3 N0 M0 thoracic ESCC. Salvage therapy can substantially improve OS after recurrence.

Objective To analyze the efficacy of IMRT in the treatment of recurrentnasopharyngeal carcinoma. Methods Clinical data of 22 patients with recurrent nasopharyngeal carcinoma ( NPC ) were retrospectively analyzed,We have recurrent NPC tune the amount of synchronization push radiation therapy in patients with clinical data,treatment efficacy and acute toxicity were analyzed.Results All patients were hospitalized on average 50 days, between median follow-up period of 12 months.At the end of 22 patients with no treatment deaths,three deaths ( both metastasis) during follow-up,overall survival 86.3%(19/22),local recurrence in 2 cases,2 cases of bone metasta-sis,1 case of throat and neck lymph node metastasis.The local control rate was 63.6%(14/22).Acute toxicity main-ly acute skin,oropharyngeal mucosa (12 cases) and bone marrow suppression (4 cases).1 patient had symptoms of hearing loss and auditory nerve damage,1 case of necrosis of the mandible,all symptoms of dry mouth in patients with radiotherapy were heavier than that of the first drive.Conclusion With the growing popularity of IMRT,NPC patients had significantly improved overall survival, but distant metastasis and recurrence of the tumor, radiotherapy again cause adverse reactions in clinical practice still needs further development and improvement,IMRT treatoffing with re-current nasopharyngeal has broad prospects.

Distinguish brain glioma recurrence for postoperative radiotherapy patients using perfusion weighted magnetic resonance imaging / 中华放射肿瘤学杂志

ObjectiveTo evaluate the role of perfusion weighted magnetic resonance imaging ( PWMRI ) in distinguishing brain glioma recurrence for postoperative radiotherapy patients.Methods Thirty-five patients with suggested recurrent brain glioma (20 true,15 false) were examined by conventional MRI and PWMRI.Regions of interests (ROI) were manually drawn in contrast-enhancing lesion,surround edema region and normal white matter of contra-lateral brain on regional cerebral blood volume (rCBV) images.rCBV values of ROI and rCBVmax were measured,the standardized rCBV ratios were calculated,The mean rCBVmax ratio were compared between two lesion types with group t-test.The rCBVmax ratios of contrastenhancing regions was analyzed by the receiver operating characteristic curve.ResultsThe mean rCBVmax ratio of contrast-enhancing lesion in tumor recurrence was higher than those in non tumor recurrence (4.36vs 1.28,t =3.00,P =0.005 ).The mean rCBVmax of edema regions in tumor recurrence was also higher than those in non tumor recurrence ( 1.79 vs 0.85,t =2.41,P =0.026).Four patients with recurrent tumor and three with non tumor recurrence were wrong diagnosed when set the recurrent tumor rCBVmax ratio ＞2.15.The diagnostic sensitivity,specificity and accuracy for recurrent tumor by PWMRI were 80％respectively.Conclusion PWMRI examination is a useful method for distinguishing brain glioma recurrence.

Comparison of effectiveness of intensity-modulated radiotherapy with conventional two-dimensional radiotherapy for patients with locally recurrent nasopharyngeal carcinoma / 中华放射肿瘤学杂志

ObjectiveTo compare the efficacy and side-effects in locally recurrent nasopharyngeal carcinoma (NPC) treated by intensity-modulated radiotherapy (IMRT) and two-dimensional conventional radiotherapy (2DCRT).MethodsAmong the 292 newly diagnosed,nonmetastatic recurrent NPC,211were treated with IMRT and 81 with 2DCRT.All patients were staged according to the seventh edition of the UICC 2009 staging system.Kaplan-Meier and Logrank methods were used for survival analysis.A Cox proportional hazard model was used to examine prognostic factors.ResultsThe follow-up rate was 91.8％,there are 38 patients in 2DCRT and 106 patients in IMRT group was followed more than 3 years.There were significant differences in the 3-year actuarial overall survival (OS) rate ( 36.9％ and 51.3％,x2 =8.44,P =0.004) and local progression-free survival (LRFS) rate (63.3％ and 86.0％,x2 =13.83,P =0.000),and no significant differences in actuarial distant metastasis free survival rates (79.0％ and 83.5％,x2 =0.25,P=0.618 ) between the 2DCRT group and the IMRT group.Multivariate analysis showed that T category and IMRT ( yes vs.no) were the independently prognostic factors for OS and LRFS ( x2 =9.51,5.20,P =0.002,0.023 and x2 =4.84,9.24,P =0.027,0.002 ).The incidence of grade 3and4 trismus and radiation-induced encephalopathy were 19.9％,8.1％ for the IMRT group and 43.2％,24.7％ for the 2DCRT group ( x2 =16.37,P =0.000 and x2 =14.64,P =0.000).Whereas,severe mucosa necrosis and/or massive hemorrhage in the nasopharynx was observed in IMRT group which was not common in 2DCRT (33.2％∶7.4％,x2 =20.19,P=0.000).ConclusionsHigher local tumor control and overall survival were achieved by IMRT than 2DCRT,the incidence of severe trismus and radiation-induced encephalopathy was also reduced by IMRT,in cost of a higher incidence of mucosa necrosis and/or massive hemorrhage in the nasopharynx.

Clinical study of laparoscopic salvage surgery for locally recurrent rectal cancer / 国际外科学杂志

Objective To investigate the safety and feasibility of reoperatively laparoscopic technique in treatment for locally recurrent rectal cancer.Methods The study enrolled 17 patients with locally recurrent rectal cancer between February 2004 and September 2009 from Shanghai Minimally Invasive Surgery Center.The patients were divided into two groups according to their pelvic recurrence types:central recurrence group (n =14) and anterior recurrence group (n =3).Demographic,surgical data and survival outcomes between two groups were compared.Results The outcomes of demographic data between two groups were not different(P＞ 0.05 ).Compared with central recurrence group,anterior recurrence group had longer operating time (P =0.028).However,the differences of operative blood loss,complications,postoperative rehabilitative outcomes and ratio of R0 resction between groups were not significant ( P ＞ 0.05 ).The overall 5- year survival rate of all the patients was 36％.And the median survival time was 42 months without significant difference between two groups (x2 =1.641,P =0.200).Conclusions Reoperatively laparoscopic technique in treatment for locally recurrent rectal cancer is safe and feasible.Selected patients,specialist operation and higer ratio of R0 resection are the key factors conducive to better short-and long-term outcomes.

De novo malignancies after liver transplantation / 中华普通外科杂志

ObjectiveTo investigate the incidence of de novo malignancies in liver transplantation recipients.MethodsWe retrospectively assessed data of 475 patients undergoing liver transplantation from May 2000 to December 2008. ResultsAmong the 475 recipients followed-up for 6 months at minimum,5 patients developed de novo malignancy and the total incidence rate was 1.1％.The median elapsed time from transplant to the diagnosis of de novo malignancy was 14 months (range 6 to 72).The patients were all males,including one of rectal cancer which was cured by radical resection,2 of hepatocellular carcinoma who died 6 and 14 months respectively after the diagnosis,1 of neuroendocrine carcinoma of the lung dying after 16 months,1 of Bukitt lymphoma who died within 2 months.Conclusions De novo malignancy is an uncommon event in liver transplantation recipients,but the outome is very poor.

Recurrence patterns of thoracic esophageal cancer after two-field lymph node dissection / 中华放射肿瘤学杂志

Objective To investigate the local-regional recurrence in thoracic esophageal cancer after radical surgery including two-field lymph node dissection and provide evidence for postoperative radiotherapy. Methods We reviewed local-regional recurrence for 134 cases with esophageal squamous cell carcinoma after radical surgery from 2004 to 2009. Results In 134 cases, lymph node metastasis rate,anastomosis recurrence rate and tumor bed recurrence rate was 94. 0%, 9. 7% and 3.7%, respectively. As to the 126 cases with lymph node metastasis, significant difference was detected between mediastinal metastasis, supraclavicular metastasis and abdominal lymph node metastasis (80. 2%, 43.7% and 13.5%,respectively, χ2= 113. 15, P = 0. 000). Furthermore, the relative metastasis rate in upper mediastinum,middle mediastinum and the lower mediastinum was 73.8%, 39.7% and 1.6%, respectively, the difference was statistically significant ( χ2 = 139. 11, P = 0. 000 ). Significant difference was identified between right and left supraclavicular lymph node metastasis (31.7% vs 16. 7%, χ2= 7. 81, P = 0. 005 ).To confirm the analysis above,lymph node metastasis rate of left recurrent laryngeal nerve nodes, (including region 1L, 2L, 4L and 5) ,right recurrent laryngeal nerve nodes, azygos nodes, subcarinal nodes, and 2R region was 38.9%, 43.7%, 15.1%, 34.1% and 25.4%, respectively. Conclusions The main characteristics of local-regional recurrence may be lymph node metastasis for esophageal squamous cell carcinoma after radical surgery. On the contrary, tumor bed recurrence is rare. Dangerous regions include supraclavicular nodes, recurrent laryngeal nerve nodes, azygos nodes as well as subcarinal nodes.

Analysis of recurrence for locally advanced gastric or gastroesophageal cancer patients after receiving curative gastrectomy ( ＞ D1 ) and its indication for adjuvant chemoradiotherapy / 中华放射肿瘤学杂志

Objective The benefit of adjuvant chemoradiotherapy remains controversial for gastric cancer patients treated with more than D1 dissection. This retrospective analysis is to distinguish the first site of recurrence in patients treated with curative resection and more than D1 dissection and to find any feasible adjuvant concurrent chemoradiotherapy recommendation for them. Methods All patients treated between January 2002 and December 2004 who met the following criteria were analyzed: primary gastric or gastroesophageal cancer, underwent curative gastrectomy ( UICC R0 ) and more than D1 lymphadenectomy,pathologically staged as T3-4N0-1 M0, or any Tx N2-3M0. There were 297 patients analyzed and 19.5%,52. 2%, 17. 8% , 10. 4% of patients had stage Ⅱ ( T3 N0 M0, T1 N2 M0 ), Ⅲa, Ⅲb and Ⅳ ( M0 ) diseases,respectively. 76. 1% of patients received adjuvant chemotherapy, while Only 2 patients underwent adjuvant radiotherapy. Failure patterns and the prognostic factors for locoregional recurrence were analyzed. Results The median follow-up time was 61 months and the follow-up rate was 92. 3%. 145 patients developed recurrence with a median recurrent time of 26 months. Locoregional recurrence was observed in 82 patients and distant metastasis in 79 patients. Gastric stump, anastomosis, intra-abdominal lymph nodes were the most common sites of locoregional recurrence. Liver and lung were the most frequent sites of distant metastasis. Prognostic variables for locoregional recurrence were identified after univariate analysis,including pathologic type ( χ2 = 11.50, P = 0. 009 ), total number of dissected lymph nodes ( χ2 = 6. 65,P =0. 010), the number of positive lymph node ( χ2 =5. 80,P =0. 016), lymph node capsular invasion ( χ2 =pathologic type, total number of dissected lymph nodes, lymph node capsular invation, AJCC TNM stage and Borrmann type were independent prognostic factors for locoregional recurrence ( χ2 = 6. 77,19. 33,17. 84 and 6. 02,P =0. 009,0. 000,0. 000 and 0. 014). ConclusionsLocoregional recurrence remains the main cause of failure for locally advanced gastric or gastroesophageal cancer patients even though the patients have had more than D1 lymphadenectomy. The role of adjuvant concurrent hemoradiotheray for those patients is warranted.

Implantation of 125Ⅰ seeds for recurrence cervical node of head and neck tumor after external beam radiotherapy / 中华放射肿瘤学杂志

Objective To summarize the efficacy and the feasibility of 125I seed implantation for recurrence cervical lymph node of head and neck tumor after radiotherapy or radiotherapy plus neck dissection. Methods Thirty-six patients with the recurrence cervical lymphnode of head and neck tumor after radiotherapy (17 patients) or radiotherapy plus neck dissection (19 patients) were treated with 125I seed implantation guided by ultrasound or CT under local anesthesia. The median number of seeds was 27( range from 3 to 78 ). Postoperative quality evaluation were routinely obtained for all patients. The actuarial D90 ranged from 90-160 Gy (median, 130 Gy). Results The follow-up rate was 100%. The number of the patients who were followed up over 1-and 2-year were 11 and 3. The overall response rate was 81%. The 1-and 2-year over local control rates, over survival rates were 69% and 35%, 50% and 22%, respectively.The 1-and 2-year local control rates in patients with recurrence node after radiotherapy plus neck dissection were 72% and 54%, while those were 67% and 50% in patients with recurrence node after radiotherapy,respectively (χ2=00,P=0.965). The 1-and 2-year survival rates in two groups were 48%, 13% , and 51%, 39%, respectively (χ2=0.17, P=0.676). Conclusions 125I seed implantation is a safe,minimal invasive with low morbidity and high efficacy salvage treatment method for cervical lymph node recurrence of head and neck tumor after radiotherapy with or without neck dissection.

Prognostic factors of patients with locally recurrent rectal cancer after radical resection / 中华放射肿瘤学杂志

Objective To investigate the prognostic factors and the clinical outcome of locally recurrent rectal cancer after radical resection. Methods From April 2000 to April 2004, 105 patients with locally recurrent rectal cancer after radical resection were re-treated in Tianjin cancer hospital. Thirty-four patients were re-treated with surgery combined with adjuvant chemoradiotherapy (group 1), 35 with surgery alone (group 2), and 36 with chemoradiotherapy (group 3). The impact of 17 clinicopathological factors and treatment modalities on the survival was analyzed. Results The follow-up rate was 95. 2%. The median survival time was 23 months. The 1-, 3-and 5-year survival rates of patients with locally recurrent rectal cancer were 63% ,34% and 19%, respectively. The 1-, 3-and 5-year survival rates were 79%, 55% and 32% in group 1 ; 68%, 40% and 14% in group 2; and 64%, 36% and 11% in group 3; respectively (χ~2 =7. 96,P =0. 019). The univariate analysis showed that the degree of differentiation, depth of tumor invasion, number of metastatic lymph nodes, initial TNM stage, recurrent location, time to recurrence, and surgery combined with adjuvant therapy were significant prognostic factors, with the last 4 being the independent prognostic factors. Conclusions Surgery combined with chemoradiotherapy may improve the survival of patients with locally recurrent rectal cancer.

Extrahepatic recurrence after curative resection of hepatocellular cancer / 中华普通外科杂志

Objective To investigate the risk factors of extrahepatie recurrences after curative resection of primary hepatocellular carcinoma (HCC). Methods Clinicopathologic data of 238 curative resected cases of primary HCC were retrospectively reviewed for parameters affecting postoperative extrahepatic recurrences. Results During a median follow-up of 34 months (7 - 78 months), extrahepatic recurrences were observed in 32 out of 238 patients (13.4%). According to univariate analysis, the risk factors for extrahepatic recurrences were preoperative serum a-fetoprotein (AFP) level of > 1000 ng/ml,aspartate aminotransferase level of > 50 IU/L, presence of hepatic vein invasion, neighboring organ invasion, tumor satellites, and lack of tumor capsule formation. Preoperative serum AFP levels of > 1000 ng/ml, hepatic vein invasion, neighboring organ invasion proved to be independent risk factors by multivariate analysis. Conclusions Extrahepatic recurrences after curative resection of HCC was found to be related to preoperative serum AFP level of > 1000 ng/ml, hepatic vein invasion, and neighboring organ invasion.

Clinical research of intraperitoneal ehemohyperthermia with NRL-002 double RF tumor hyperthermia system on recurrent ovarian cancer / 肿瘤研究与临床

Objective To study the efficacy of intraperitoneal chemohyperthermia with Double RF Tumor Hyperthermia System on recurrent ovarian cancer. Methods 22 cases of advanced recurrent ovarian cancer were infused with hot NS and DDP and VP16 in abdominal cavity, NRL-002 double RF Tumor Hyportherrnia System was applied to heat the abdominal part for 60-120 minutes. RF hyperthermia was given twice per week and chemotherapy once per week. Results The overall response rate (CR+PR) was 63.6%. The serum CA125 ratio was decreased significantly. The level of CD4/CD5 and NK cells was higher than that of pretherapy after management. The clinical beneficial response(CBR) was 81.8%. The median TIP and MST were 7.8 mouth and 18.5 month. Conclusion Intraperitoneal ehemohyporthermia with NRL-002 Double RF Tumor Hyperthermia System was an effective way to treat advanced recurrent ovarian cancer. It Can also improve life quality of patients with mild adverse effect and recommended to be applied clinically.
