ABSTRACT
Pancreatic hepatoid carcinoma (PHC) is a rare neoplasm that shares differentiation features with hepatocellular carcinoma. It is a special type of adenocarcinoma which can be accompanied by elevated serum AFP. PHC is highly invasive, and has a poor prognosis, and it usually present with vascular invasion, liver and/or lymph node metastasis. Preoperative diagnosis of PHC is difficult, and there is currently no consensus on its diagnosis and treatment. A better understanding of PHC is helpful to improve its diagnostic rate and to allow timely and effective application of treatment. This article reviews the research progress on PHC.
ABSTRACT
Objective:To compare the efficacy of laparotomy and laparoscopic Glisson pedicle transecting segmental hepatectomy in the treatment of hepatocellular carcinoma.Methods:The clinical data of 138 patients with hepatocellular carcinoma who underwent Glisson pedicle transection hepatectomy in the Affiliated Hospital of Chengde Medical College from March 2012 to November 2015 were collected retrospectively. 45 patients underwent laparoscopic surgery (laparoscopic group) and 93 patients underwent laparotomy. 45 patients were selected as open group according to the most clinical ratio of propensity score. The baseline data, operation, stress index, liver function index and postoperative survival rate were compared between the two groups. COX proportional hazard regression model was used to analyze the influencing factors of 5-year prognosis. Normally distributed measurement data were expressed as mean±standard deviation ( Mean± SD), and independent sample t test was used for comparison between groups. The chi-square test was used to compare the enumeration data between groups. Results:The operation time, intraoperative blood loss, blood transfusion cases, complications, postoperative eating time, drainage tube removal time, and hospital stay in the laparoscopic group were (219.48±53.61) min, (208.53±39.74) mL, 2, 3, (3.62±0.51) d, (4.73±0.85) d, (10.59±1.37) d, the open group were (185.37±46.92) min, (267.49±35.83) mL, 8, 10, (4.56±0.73) d, (5.29±0.94) d, (13.87±1.68) d, the differences between the two groups were statistically significant ( P<0.05). Cortisol, norepinephrine, C-reactive protein, aspartate aminotransferase, alanine aminotransferase, total bilirubin in the postoperative laparoscopic group) And albumin levels were (258.39±30.76) ng/mL, (66.78±7.31) ng/mL, (28.39±3.45) μg/mL, (66.51±7.14) U/L, (73.39±7.85) U/L, (20.67±2.74) μmol/L, (37.52±6.48) g/L, the open group were (316.92±37.51) ng/mL, (75.63±8.39) ng/mL, (38.47±4.56) μg/mL, (82.39±9.06) U/L, (94.05±9.74) U/L, (22.93±3.18) μmol/L, (34.65±5.87) g/L, the differences between the two groups were statistically significant ( P<0.05). There were no statistically significant difference in overall survival rate and tumor-free survival rate between the laparotomy group and the laparoscopic group at 1, 3, and 5 years after surgery ( P>0.05). The COX proportional hazards regression model showed that HBsAg positive, Child-Pugh grade, alpha-fetoprotein, and tumor diameter were risk factors affecting the 5-year prognosis of patients ( HR=6.627, 7.518, 5.143, 4.881, 95% CI: 1.516-9.738, 2.382-12.495, 3.078-6.249, 1.925-7.723, P<0.05). Conclusion:The long-term effects of laparotomy and laparoscopic Glisson pedicle transection hepatectomy are the same in selective hepatocellular carcinoma cases, but laparoscopic surgery can reduce intraoperative blood loss, blood transfusion cases and complications, facilitate early removal of drainage tube and food intake, shorten hospital stay, reduce stress reaction, and promote the recovery of liver function, so the short-term effect is better.
ABSTRACT
Objective:This study aimed to establish an eXtreme Gradient Boosting(XGBoost) model that can predict the recurrence of hepatocellular carcinoma(HCC)patients after laparoscopic hepatectomy (LH) surgery.Methods:A total of 440 patients with primary HCC who received LH treatment for the first time from January 2013 to September 2016 in Affiliated Hospital of Chengde Medical University were selected as the research objects. The diagnosis method was pathological diagnosis. Research objects were divided into training group ( n=88) and verification group ( n=352) at a ratio of 2∶8 by random number table method. The Kaplan-Meier method was used to draw the recurrence-free survival curve, and the Log-rank test was used to compare the survival of the two groups; the training group was used to establish the COX regression model and the XGBoost model to screen independent predictors of recurrence after LH; receiver operating characteristic(ROC) curve was used to analyze the predictive abilities of the two models, and conducted internal verification in the verification group; Hosmer and Lemeshow Test was used to evaluate the calibration of the two models, and P>0.05 was used as a good fit between the model and the actual situation. Results:Both the COX regression model and the XGBoost model screened out tumor thrombus, low degree of differentiation, tumor microvascular infiltration (MVI), number of tumors, large tumors, and positive hepatitis B surface antigen were independent predictors of tumor recurrence( HR=2.477, 0.769, 1.786, 1.905, 1.544, 1.805; 95% CI: 1.465-4.251, 0.619-0.819, 1.263-2.546, 1.354-2.704, 1.272-1.816, 1.055-2.555). The XGboost model scores were 32 points, 29 points, 24 points, 18 points, 16 points, 11 points, respectively. In the training group, the area under the curve (AUC) of the COX regression model and XGBoost model for predicting recurrence were 0.746 (0.730-0.762) and 0.802 (0.785-0.818), respectively. The XGBoost model had strong predictive ability and was confirmed in the validation cohort. Conclusions:This study had established and verified the XGBoost model that can predict the recurrence of HCC patients after receiving LH for the first time. It can be used in clinics to assist doctors in formulating personalized postoperative monitoring programs for patients. Early detection, early diagnosis and early treatment of tumors and strengthening of postoperative follow-up are important measures to improve the prognosis of patients.
ABSTRACT
Background@#In China, secondary cytoreductive surgery (SCR) has been widely used in ovarian cancer (OC) over the past two decades. Although Gynecologic Oncology Group-0213 trial did not show its overall survival benefit in first relapsed patients, the questions on patient selection and effect of subsequent targeting therapy are still open. The preliminary data from our pre-SOC1 phase II study showed that selected patients with second relapse who never received SCR at recurrence may still benefit from surgery. Moreover, poly(ADP-ribose) polymerase inhibitors (PARPi) maintenance now has been a standard care for platinum sensitive relapsed OC. To our knowledge, no published or ongoing trial is trying to answer the question if patient can benefit from a potentially complete resection combined with PARPi maintenance in OC patients with secondary recurrence. @*Methods@#SOC-3 is a multi-center, open, randomized, controlled, phase II trial of SCR followed by chemotherapy and niraparib maintenance vs chemotherapy and niraparib maintenance in patients with platinum-sensitive second relapsed OC who never received SCR at recurrence. To guarantee surgical quality, if the sites had no experience of participating in any OC-related surgical trials, the number of recurrent lesions evaluated by central-reviewed positron emission tomography–computed tomography image shouldn't be more than 3. Eligible patients are randomly assigned in a 1:1 ratio to receive either SCR followed by 6 cyclesof platinum-based chemotherapy and niraparib maintenance or 6 cycles of platinum-based chemotherapy and niraparib maintenance alone. Patients who undergo at least 4 cycles of chemotherapy and must be, in the opinion of the investigator, without disease progression, will be assigned niraparib maintenance. Major inclusion criteria are secondary relapsed OC with a platinum-free interval of no less than 6 months and a possibly complete resection. Major exclusion criteria are borderline tumors and non-epithelial ovarian malignancies, received debulking surgery at recurrence and impossible to complete resection. The sample size is 96 patients. Primary endpoint is 12-month non-progression rate.
ABSTRACT
Background@#Two randomized phase III trials (EORTC55971 and CHORUS) showed similar progression-free and overall survival in primary or interval debulking surgery in ovarian cancer, however both studies had limitations with lower rate of complete resection and lack of surgical qualifications for participating centers. There is no consensus on whether neoadjuvant chemotherapy followed by interval debulking surgery (NACT-IDS) could be a preferred approach in the management of advanced epithelial ovarian cancer (EOC) in the clinical practice. @*Methods@#The Asian SUNNY study is an open-label, multicenter, randomized controlled, phase III trial to compare the effect of primary debulking surgery (PDS) to NACT-IDS in stages IIIC and IV EOC, fallopian tube cancer (FTC) or primary peritoneal carcinoma (PPC).The hypothesis is that PDS enhances the survivorship when compared with NACT-IDS in advanced ovarian cancer. The primary objective is to clarify the role of PDS and NACT-IDS in the treatment of advanced ovarian cancer. Surgical quality assures include at least 50% of no gross residual (NGR) in PDS group in all centers and participating centers should be national cancer centers or designed ovarian cancer section or those with the experience participating surgical trials of ovarian cancer. Any participating center should be monitored evaluating the proportions of NGR by a training set. The aim of the surgery in both arms is maximal cytoreduction. Tumor burden of the disease is evaluated by diagnostic laparoscopy or positron emission tomography/computed tomography scan. Patients assigned to PDS group will undergo upfront maximal cytoreductive surgery within 3 weeks after biopsy, followed by 6 cycles of standard adjuvant chemotherapy. Patients assigned to NACT group will undergo 3 cycles of NACT-IDS, and subsequently 3 cycles of adjuvant chemotherapy. The maximal time interval between IDS and the initiation of adjuvant chemotherapy is 8 weeks. Major inclusion criteria are pathologic confirmed stage IIIC and IV EOC, FTC or PPC; ECOG performance status of 0 to 2; ASA score of 1 to 2. Major exclusion criteria are non-epithelial tumors as well as borderline tumors; low-grade carcinoma; mucinous ovarian cancer. The sample size is 456 subjects. Primary endpoint is overall survival.

ABSTRACT
Objective@#To evaluate the effect of low-dose hormone replacement therapy（HRT）on menopausal-related symptoms in young patients with cervical squamous cell carcinoma.@*Methods@#From March 2016 to September 2018,eighty patients aged 45 years below with cervical squamous cell carcinoma of stage Ⅰ-Ⅱ and iatrogenic menopause were recruited,who were diagnosed at Zhejiang Cancer Hospital and Women's Hospital Affiliated to Medical College of Zhejiang University. Fourty of them performed low dose HRT（1 mg estradiol valerate a day or 1.25 mg tibolone a day）,twenty performed standard dose HRT（1 mg estradiol valerate and 1.25 mg tibolone a day）,another twenty do not perform HRT as a control group. The levels of follicle stimulating hormone（FSH）,estradiol（E2）,menopausal symptoms（the improved Kupperman score）and incidence of side effects were assessed before and 1,3,6 months after the intervention. @*Results@#There were significant differences in E2 levels,FSH levels and improved Kupperman scores among the low dose group,the standard dose group and the control group（all P<0.05）. With the extension of intervention time,E2 levels in the low dose group and the standard dose group increased first and then decreased,FSH levels and improved Kupperman scores decreased（all P<0.05）. Compared with the control group,E2 levels,FSH levels and improved Kupperman scores in the standard dose group changed more significantly（all P<0.05）. E2 and FSH levels in the low dose group changed less than that in the standard dose group（all P<0.05）,while improved Kupperman scores was close to that in the standard dose group. The incidence rate of side effects in the low dose group was 2.50%,which was lower than 20.00% in the standard dose group（P<0.05）. @*Conclusion@#For young patients with cervical squamous cell carcinoma,using low dose HRT may less affects E2 and FSH levels than using the standard dose,but could achieve similar effects in treatment of menopausal-related symptoms.
ABSTRACT
Objective To systematically evaluate the risk factors for ovarian metastasis of endometrial carcinoma(EC) to provide an evidence-based medicine basis for formulating the EC surgical mode and ovarian metastatic risk.Methods Studies about the risk factors for EC ovarian metastasis were retrieved by computer from the Pubmed,Embase,Cochrane Library,WanFang database,CNKI,China Biology Medicine(CBM) from Jan.1,1990 to Sep.1,2016.The quality evaluation of included literature was performed by using the Newcastle-Ottawa Scale(NOS).Results A total of 13 studies were included,involving 6 140 EC patients,of whom 344 cases(5.60％) had ovarian metastasis.The Meta analysis results showed that a total of 9 factors had statistical significance,which were deep myometrial infiltration(OR =0.28,95 ％ CI:0.21-0.39),cervical involvement (OR =0.27,95 ％ CI:0.16-0.45),lymph node involvement (OR =0.21,95 ％ CI:0.15-0.27),fallopian tube involvement (OR =0.05,95 ％ CI:0.02-0.10),non-endometrioid adenocarcinoma(OR=0.32,95％CI:0.24-0.43),low differentiation(OR=0.39,95％CI:0.31-0.50),positive ascites cytologic detection(OR=0.14,95％CI:0.09-0.20),high serum CA125 level(OR=0.12,95％CI:0.08-0.19) and lymphovascular cancer embolus(OR =0.34,95 ％ CI:0.23-0.50),the differences were statistically significant(P＜0.05).But the age,lesion location,lesion diameter and estrogenic receptor level had no statistical difference(P＞0.05).Conclusion Deep myometrial infiltration,cervical involvement,lymph node involvement,fallopian tube involvement,non-endometrioid adenocarcinoma,low differentiation and positive ascites cytologic detection,high CA125 level and lymphovascular cancer embolus are the risk factors for EC ovarian metastasis.
ABSTRACT
Objective To investigate the metabolite changes in the preschool children with autism spectrum disorder (ASD) using MR spectroscopy (MRS) and explore the associations between image findings and clinical variables, which may provide a noninvasive brain biochemical method for the early diagnosis and prevention of autism. Methods Twenty one cases of preschool ASD children (3-6 years old) and age-and sex-matched 20 preschool healthy controls underwent single voxel short (SVS) short TE (TE=30 ms) MRS. The absolute metabolite concentrations in the anterior cingulate cortex (ACC) , anterior middle anterior cingulate cortex (aMCC) and posterior cingulate (PCC) were quantitatively analyzed using LCModel software. Two independent sample t tests were used for analysis. The relationships between metabolite concentrations and diagnostic and statistical manual of mental disorders (DSM-IV) , childhood autism rating scale (CARS) and autism behavior checklist (ABC) were analyzed by Pearson correlation analysis. Results Compared to control subjects, ASD patients had significantly lower N-acetylaspartate (NAA) values (4.35 ± 0.80, 6.34±0.82, 8.04±0.97 mmol/L respectively) in ACC, aMCC and PCC (t=2.640, P=0.012;t=2.182, P=0.035;t=3.343, P=0.002) , had significantly lower choline (Cho) 1.32±0.22 mmol/L (t=2.905, P=0.006) and glutamine and glutamate complex (Glx) 10.02 ± 0.88 mmol/L (t=2.090, P=0.043) in PCC. Cho, total creatine (tCr) , myo-Inositol (MI) and Glx levels did not differ between groups in other aforementioned regions (P>0.05). Negative correlations between the NAA ualues in the PCC and CARS (r=-0.504, P=0.020) were detected, and no significant correlation among DSM-IV, CARS, ABC and other metabolite values (P>0.05). Condnsions The biochemical changes in the preschool children with ASD in cingulate reflect the neuronal loss, structural or functional damage and cell membrane enzyme metabolic dysfunctions, may reveal the pathological basis of ASD. These results may provide noninvasive and quantitative methods for the diagnosis and prognosis evaluation of ASD child.
ABSTRACT
Objective To compare the curative effect of laparoscopic and laparotomic operation for elderly Chinese women with cervical cancer. Methods The randomized controlled trials (RCT) and case controlled trials (CCT) were collected by searches of WanFang database, CNKI, VIP, China Biology Medicine (CBM) , PubMed. Data were extracted from these trials and data analysis was performed by RevMan 5.2.9. Results There were no RCTs, however, a total of 10 CCTs met the inclusion criteria and had data extracted for this review. The baseline characteristics of the laparoscopic group were similar to those of the laparotomic group. Comparing to laparotomic group, the laparoscopic group have longer operation time (MD =32.60, 95%CI: 5.65~59.55, P = 0.020), less amount of bleeding (MD = -94.01, 95%CI: -130.65 ~ -57.37, P = 0.000), smaller number of lymph node dissection(MD = 1.69, 95%CI: 0.67 ~ 2.72, P = 0.001), earlier anus exhaustion (MD=-17.09, 95%CI: -21.19 ~ -12.98, P = 0.000) and shorter hospital stays (MD = -4.30, 95%CI: -5.57 ~ -3.02, P = 0.000). There was significant difference between the two groups. But there was no statistical significance in postoperative indwelling catheter time (MD = -0.67, 95%CI: -1.92 ~ 0.58, P = 0.290) and surgical complications incidence (OR=0.62, 95%CI: 0.27 ~ 1.42, P = 0.260) between the two groups. Conclusion Laparoscopic management has the advantages of less traumatic and recovered quickly, and did not increase the incidence of complications. Laparoscopic operation is an ideal procedure for elderly Chinese women with cervical carcinoma.
ABSTRACT
Objective To analyze the clinicopathologic features and prognosis of early stage cervical adenosquamous carcinoma and adenocarcinoma.Methods Clinical data of 62 patients with cervical adenosquamous carcinoma,149 patients with adenocarcinoma and 2 687 patients with squamous carcinoma of stage Ⅰ B-Ⅱ A,who received surgical treatment and adjuvant radiotherapy from June 2006 to February 2012 were retrospectively analyzed.The Chi-square test,Kaplan-Meier method,log-rank test and logistic regression were used for statistical analysis.Results In patients with adenosquamous carcinoma,adenocarcinoma and squamous carcinoma,the rates of lymph node metastasis were 33.6％ (50/149),29.0％ (18/62) and 22.0％ (591/2 687),deep stromal invasion were 64.4％ (96/149),75.8％ (47/62) and 55.3％ (1 486/ 2 687) and corpus invasion were 26.2％ (39/149),25.8％ (16/62) and 6.7％ (181/2 687),respectively.Those pathological parameters in adenosquamous carcinoma and adenocarcinoma were higher than those in squamous carcinoma (χ2 =12.170,P=0.002;χ2 =14.660,P=0.001;χ2 =97.732,P=0.000).There were no difference between adenocarcinoma and adenosquamous carcinoma in proportion of massive tumor (≥4 cm) [38.9％ (58/149) vs.35.5 (22/62),χ2 =0.220,P =0.639],lymph node metastasis (χ2 =0.410,P =0.522),corpus invasion (χ2 =0.003,P =0.956),deep stromal invasion (χ2 =2.595,P =0.107) and low differentiation[38.9％ (58/149) vs.48.4％ (30/62),χ2 =1.612,P=0.204].The median follow-up period was 45 (3-92) months.Multivariate analysis showed that corpus invasion (P =0.014,RR =3.393,95％CI:1.280-8.991),age (P=0.000,RR =1.077,95％ CI:1.037-1.117) and stage (P =0.007,RR =0.275,95％ CI:0.108-0.699) were prognostic factors of adenosquamous carcinoma.Age (P =0.006,RR =1.025,95 ％ CI:1.007-1.043) and lymph node metastasis (P =0.000,RR =2.525,95％ CI:1.547-4.120) affected the prognosis of adenocarcinoma.The median survival times for adenocarcinoma,adenosquamous carcinoma and squamous carcinoma were 45,46 and 56 months (adenosquamous carcinoma vs.squamous carcinoma:χ2 =1.347,P =0.246;adenosquamous carcinoma vs.adenocarcinoma:χ2 =1.808,P=0.179).There were no difference in recurrence rates between adenosquamous carcinoma and squamous carcinoma[14.0％ (7/50) vs.7.6％ (175/2 298),χ2 =1.968,P=0.161],and between adenosquamous carcinoma and adenocarcinoma [14.0％ (7/50) vs.22.1％ (27/122),χ2 =1.478,P =0.224].Conclusions Clinicopathologic features are similar between stage Ⅰ B-Ⅱ A cervical adenosquamous carcinoma and adenocarcinoma.Corpus invasion,age and stage are the leading indicators affecting the prognosis of adenosquamous carcinoma.Age and lymph node metastasis are the factors affecting the prognosis of adenocarcinoma.There are no difference in survival and prognosis between adenosquamous carcinoma and adenocarcinoma.
ABSTRACT
Objective To investigate the efficacy of postoperative concurrent chemoradiotherapy for early-stage cervical adenosquamous carcinoma and adenocarcinoma.Methods A total of 62 patients with cervical adenosquamous carcinoma,149 patients with cervical adenocarcinoma,and 2687 patients with cervical squamous cell carcinoma,all of whom were in stage Ⅰ B-Ⅱ A and were treated from 2006 to 2012,were enrolled,and some of them received postoperative pelvic radiotherapy ± para-aortic extended field radiation ±afterloading radiotherapy.The chemotherapy regimen consisting of DDP,TP,and FP was given to these patients.The chi-square test was used for comparison of general clinical data,the Kaplan-Meier method was used for calculating survival rates,and the log-rank test was used for survival difference analysis.Results Cervical adenosquamous carcinoma and adenocarcinoma had no significant differences in clinicopathological features (P=0.107-0.639).The high-risk patients with adenocarcinoma had a higher recurrence rate than their low-risk counterparts even after adjuvant radiotherapy or chemoradiotherapy (P=0.000).In the patients treated with surgery and radiotherapy,those with adenosquamous carcinoma had the shortest median survival time,followed by those with adenocarcinoma and squamous cell carcinoma (P =0.134,0.787);in the patients treated with surgery and concurrent chemoradiotherapy,those with adenocarcinoma had the shortest median survival time,followed by those with adenosquamous carcinoma and squamous cell carcinoma (P=0.131,0.643),and the median survival time showed a significant difference between the patients with adenocarcinoma and those with squamous cell carcinoma (P =0.000).In the patients with adenosquamous carcinoma and adenocarcinoma,the patients treated with postoperative concurrent chemoradiotherapy had higher incidence rates of short-term adverse reactions than those treated with postoperative radiotherapy (P=0.037,0.003),but the incidence rates of long-term adverse reactions showed no difference between the two groups of patients (P=0.861,0.655).In the patients with adenosquamous carcinoma,the patients treated with postoperative concurrent chemoradiotherapy had a lower rate of distant metastasis (P =0.003) and prolonged median overall survival and disease-free survival (both increased by 17 months) (P=0.811,0.799),as compared with those treated with postoperative radiotherapy,while in the patients with adenocarcinoma,the median overall survival and disease-free survival were reduced by 11 and 9 months,respectively (P=0.330,0.115).Conclusions Compared with postoperative radiotherapy,postoperative concurrent chemoradiotherapy for early-stage high-risk cervical adenosquamous carcinoma can reduce the rate of distance metastasis.Compared with radiotherapy,postoperative concurrent chemoradiotherapy for adenosquamous carcinoma and adenocarcinoma cannot improve survival time.
ABSTRACT
Objective To explore the impact and prediction of social support, life stress, coping style on learning burnout in middle school students.Methods A total of 306 middle school students were investigated with adolescent student burnout inventory, middle shool psychological stressors questionnaires, social support rating scale for juveniles and simplified coping style questionnaire.Results The scores of learning burnout were 44.30±8.45.The moderate learning burnout accounted for 31.9％.There were no differences between social support,life stress,coping style(P＞0.05).There were significant differences in social support ((46.57± 12.50) vs (50.03 ± 10.63))between male and female(t=-2.536, P＜0.05).There was positive correlation between learning burnout and life stress and negative coping style(r=0.146-0.301, P＜0.05) ,and negative correlation between learning burnout and social support and positive coping style (r=-0.301--0.231, P＜0.01).The learning stress (β=0.435), teacher stress (β=0.157), support availability (β=-0.204), negative coping style (β=2.668) were the mainly influencing factors of learning burnout in middle school students ,which can predict 26.4％ variation of learning burnout in middle school students.Conclusion Learning stress, teacher stress, support availability, negative coping style are the mainly influencing factors of learning burnout in middle school students.
ABSTRACT
Treatment of gynaeeological cancer frequently results in the loss of ovarian function and menopausal syndrome.The most effective treatment is hormone replacement therapy (HRT).According to the current studies,HRT does not increase the risk of recurrence or death in patients with early stage endometrial cancer and uterine leiomyosarcomas. The safety of HRT in ovarian cancer patients is inconclusive. Cervical squamous cell carcinoma, vaginal cancer and vulvar cancer are not contraindications for HRT. Estrogen replacement therapy (ERT) is contraindicated for low-grade endometrial stromal sarcomas. Therefore,after integrated risk assessment and discussion,patients with severe menopausal symptoms can be treated with HRT to improve the quality of life.
ABSTRACT
Objective To investigate the pathogenesis,high risk factors,clinical characteristics,methods of diagnosis and treatment,and prognosis of vaginal intraepithelial neoplasia (VAIN).Methods The clinical data of thirteen cases of VAIN treated in Zhejiang Provincial Cancer Hospital dated Mar.2002 through Dec.2008 were reviewed and analyzed retrospectively.Results Twelve of 13 VAIN cases were performed the human papillomavirus(HPV) detection with 92% (11/12) HPV positive rate.None of the cases shown specific clinical manifestation.Among the 13 cases,6 of them accompanied with cervical cancer,4 cases with cervical intraepithelial neoplasia (CIN ),and 3 cases with vulvar intraepithelial neoplasma (VIN).Five cases synchronously diagnosed with cervical lesion and 3 with vulva lesion were underwent surgery,while the other 5 cases were diagnosed metachronously.Among 8 cases underwent surgery,1 case with CIN underwent argon plasma coagulation (APC) after surgery,1 case with the positive edge of VIN underwent APC.During follow up,1 case with locally advanced cervical cancer underwent radiotherapy again,3 cases with VAIN received APC,while 1 cervical cancer cases with VAIN received no treatment.The average follow-up time was 25.6 months (range 6-87 months).Two cases died of cervical cancer metastasis.The other 11 cases were normal and still alive.None of them progressed to invasive carcinoma.Conclusions The main reason of VAIN is HPV infection.There are not specific clinical manifestations,usually diagnosed when reviewing cervical or vulva lesions and rarely progressed to invasive carcinoma.The main treatment of VAIN is surgery with the adjuvant treatment of APC.
ABSTRACT
<p><b>OBJECTIVE</b>To study the clinicopathologic characteristics, prognostic factors, response to chemotherapy, chemotherapy-caused disease-free interval and overall survival of small cell carcinoma of uterine cervix (SCCUC).</p><p><b>METHODS</b>Twelve patients with SCCUC were treated from 1995 to 1999, with their clinic ophathologic data retrospectively analyzed. Their stages were I b(1) 2, I b(2) 4, II a 3, II b 1, III b 1 and IV b1. All 12 samples were assessed through immunohistochemical methods including epithelial cell markers and neuroendocrine cell markers, showing positive results in all. Nine early stage patients underwent radical hysterectomy with pelvic lymphadenectomy. Five of these 9 patients had received neoadjuvant chemotherapy (NCH) once or twice before operation, three patients received adjuvant chemotherapy (ACH) once to six times after operation. Three patients with advanced lesions received concurrent chemotherapy twice to four times.</p><p><b>RESULTS</b>44.4% (4/9) of patients treated by pelvic lymphadenectomy showed positive lymph node metastasis. The average disease free intervals of patients who showed positive or negative pelvic lymph node were 16.1 and 25.7 months, overall survival of 19 and 32 months. The success rate of surgery in the NCH group was 100%, 60% of whom showed chemotherapy response pathologically. They showed overall response rates of 80% (4/5), 20% CR (1/5) and 60% PR (3/5).</p><p><b>CONCLUSION</b>Poor prognosis of small cell carcinoma of uterine cervix, even the early lesions, is due to its high incidence of pelvic lymph metastasis. The risk factor of this lesion is high sensitivity to chemotherapy, but chemotherapeutic long-term survival should be studied further with more allotted material.</p>
