Disease response pattern of 127 T1B·1RS translocation and substitution wheat cultivars, possessing powdery mildew resistance gene Pm8 and leaf rust resistance gene Lr26 located on rye chromosome arm 1RS, revealed that sixteen of these cultivars express Lr26, but not concomitant Pm8 resistance. The mode of inheritance studied in the F[sub 1], F[sub 2] and F[sub 3] generations, and involving hybrids of cultivars Agra, Florida, Olymp, Sabina and Tjelvar not expressing Pm8 resistance indicated inhibition of resistance gene Pm8 by a dominant suppressor.

Objective: The aim of this study was to assess the effect of increasing surgeons’s experience in the laparoscopic surgery of women with endometrial cancer (EC) on the surgical outcome of these patients. Study design: Data were obtained from a prospectively collected database of 108 patients two oncolaparoscopic centers in Czech Republic who underwent laparoscopically assisted surgical staging (LASS) from April 1996 to March 2001. Patients were arranged in chronological order and divided into three groups, based on the date of their surgery. The three groups were compared in patient characteristics and surgical outcome using one-way analysis of variance (ANOVA) and Wilcoxon rank sum test. Setting: Department of Obstetrics and Gynecology, Endoscopic Training Center, Baby Friendly Hospital Kladno, Czech Republic. Results: The three groups were similar in patient characteristics. Operative times for laparoscopic staging with pelvic lymphadenectomy (LN) decreased significantly from mean of 156.3 min for group 1 to 142.8 min for group 3 (P<0.05). In cases LASS with pelvic lymphadenectomy was significant increase in the number lymph nodes harvested (12.4 for group 1, 13.9 for group 2, and 15.4 for group 3, P<0.05). In cases LASS without lymphadenectomy was not significant difference in operating time, estimated blood loss, rate of conversion to laparotomy, operative complications, and length of hospital stay among the compared groups. The number of patients who underwent para-aortic lymphadanectomy was too small (n=22), and their distribution was asymmetrical for comparison. Conclusion: A learning curve is demonstrated in the LASS of women with endometrial cancer. With increasing surgeon’s team experience, there is significant decrease in operative time for staging with pelvic lymph node dissection and increase in the number of pelvic lymph nodes removed. The para-aortic lymphadenectomy (PALN) was found to be more challenging than pelvic lymphadenectomy. [Copyright &y& Elsevier]

Objective: To analyze the results and determine the contribution of laparoscopic pelvic lymphadenectomy in the surgical treatment of women with endometrial cancer and compare with the open technique., Methods: A prospective multicenter study was carried out on 120 women who underwent laparoscopic surgery (96 women) and open procedures (24 women) for endometrial cancer between April 1996 and March 2000., Results: Four patients whose laparoscopic surgery was completed by laparotomy were excluded from the study. The other 92 laparoscopic procedures were successfully completed. Laparoscopically assisted surgical staging (LASS) was performed based on the grade of the tumor and the depth of myometrial invasion. Sixty-seven of the patients underwent hysterectomy, bilateral salpingooophorectomy (BSO), and pelvic lymphadenectomy, and 25 women also had para-aortic lymph node sampling dissection. Eleven of these patients had positive pelvic or para-aortic nodes. The mean operating time for the laparoscopic procedure was significantly longer (173.8 min, P < 0.0001) than the time for the open procedure (135.0 min). The rate of complications was similar in both groups. The recovery time was significantly reduced (P < 0.0001)., Conclusion: The laparoscopic approach to hysterectomy and lymphadenectomy for early stage endometrial carcinoma is an attractive alternative to the abdominal surgical approach. The advantages of laparoscopically assisted surgical staging are patient related. Because the abdominal incision is avoided, the recovery time is reduced. Laparoscopic pelvic lymph node dissection is a procedure that is appropriate, when applicable.
