A Feasibility Study of Postoperative Adjuvant Therapy of Carboplatin and Weekly Paclitaxel for Completely Resected Non-small Cell Lung Cancer
IntroductionRecent clinical trials have shown significant survival benefits from postoperative adjuvant therapy for respectable nonsmall cell lung cancer (NSCLC). However, evaluation of adjuvant chemotherapy with carboplatin combination is still uncertain. The purpose of the study was to test the feasibility of adjuvant chemotherapy with carboplatin and separate weekly paclitaxel after complete resection of pStage IB, II, IIIA NSCLC in a multicenter study.MethodsThe study was conducted from 2001 to 2006 in the outpatient setting. A total of 61 patients were enrolled. Patients received adjuvant chemotherapy with 4 cycles of carboplatin (AUC 5) on day 1 and paclitaxel (70 mg/m2) on day 1, 8, and 15 every 4 weeks. Primary endpoints were toxicity and chemotherapy compliance. Secondary endpoints were disease-free survival and overall survival.ResultsMore than 65% of eligible patients had pStage IIIA. The median number of chemotherapy cycles was 4 (range 1–4). Grade 3 or 4 toxicities of neutropenia were 34% (grade 4: 2%). Other hematologic adverse effects were extremely less frequent. Regarding the nonhematologic adverse effect, hair loss was frequent; however, peripheral neuralgia was less frequent. Treatment-related death was not registered. During median follow-up of 21 months, 24 patients developed recurrent disease. Estimated disease-free survival and overall survival at 2 years was 51.2% and 84.6%, respectively.ConclusionsPostoperative carboplatin and weekly paclitaxel showed favorable feasibility and acceptable toxicity in comparison with the cisplatin-containing regimen. Consequently, it is desirable that this regimen would be validated in a phase III clinical trial for NSCLC after curative resection
Adult Intussusception Due to Endometriosis Arising from the Uterine Tube: Report of a Case
Introduction: Endometriosis is a rare cause of intussusceptions in adults. Although intestinal endometriosis sometimes arises as a consequence of direct involvement of the pelvic organs with endometrial tissue, there is no report that this type of endometriosis causes ileocecal intussusception.
Case presentation: Computed tomography assessment of a 40-year-old woman who presented with abdominal pain revealed ileocecal intussusceptions. The patient was managed by endoscopic reduction followed by laparoscopic resection. Adhesion between the right uterine adnexa and caecum was identified during surgery; therefore, combined resection of the uterine adnexa and ileocecum was performed. Pathological findings revealed that endometriosis, arising from the uterine tube and directly involving the cecal wall, had caused the intussusceptions.
Conclusion: Although rare, endometriosis should be considered as part of a differential diagnosis of intussusception in adult women who present with abdominal pain. A preoperative diagnosis is sometimes difficult, therefore, surgical resection could be a reasonable strategy to achieve a precise diagnosis
A4-06: Patients-oriented prospective study in comparison between two types of VATS lobectomy for clinical T1N0 lung cancer
Investigation of Suitability of Devascuralized Upper Half of the Whole Stomach as Replacement for the Esophagus
One hundred and fifteen patients with esophageal cancer underwent esophageal replacement with the stomach. The patients were divided into group A (52 patients, stomach tube, ante- or retro-sternal route) and group B (54 patients, devascuralized upper half of the whole stomach, posterior mediastinal route). The post-operative complications, post operative symptoms and nutritional status were investigated in both groups. Lung complications tended to occur more frequently in group A (28.8% versus 22.2%), showing no significant difference. The incidence of other complications did not show a remarkable difference between either group except for leakage at the site of anastomosis. Major leakage occurred in 11.5% and 5.6%, and minor leakage in 30.8% and 18.5%, respectively. Postprandial fullness, nausea, heart burn and diarrhea were found to be somewhat higher in Group B. Change of oral intake, body weight and other indices of nutritional status were investigated and compared with pre- operative data. The amount of oral intake and levels of serum albumin was higher in group B than in group A between one and 12 months. These results demonstrate the superiority of the devascuralized upper half of the whole stomach as an esophageal substitute
Investigation of Suitability of Devascuralized Upper Half of the Whole Stomach as Replacement for the Esophagus
Willingness to Work and the Working Environment of Japanese Dental Hygienists
Japanese dental hygienists’ employment rate is low. The environment factors and daily job contents that contribute to willingness to work of Japanese dental hygienists and their structures were investigated. A cross-sectional survey was conducted using a self-administered postal questionnaire distributed for one thousand and twenty-three members of Japan Dental Hygienist Association registered in Iwate prefecture affiliation. Three items concerning willingness to work, satisfaction for the 9 items about working environment, anxiety for work, and 106 daily job contents were used for analysis. Structural equation modeling, decision analysis, and correspondence analysis were carried out. The present study found that working environment such as interpersonal relationship was more important than social environment such as salary for the regular employee of Japanese dental hygienist working at private dental office. However, salary was only the determinant for the dental hygienist who strongly disliked their work. And daily job contents affected the willingness to work. Especially, jobs concerned with prosthodontic treatments were of major concern. Improving the working environment and avoiding assignment of tasks that require lower level of skill may improve dental hygienists’ willingness to work and may assist to improve the employment rate of dental hygienist in Japan
