Laparoscopic surgery compared to traditional abdominal surgery in the management of early stage cervical cancer

The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy.

METHODS

Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program.

RESULTS

Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups.

CONCLUSION

There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

COX-2 expression and clinical outcome in early-stage breast cancer patients treated with adjuvant chemotherapy: A prospective study

e22165

Background: To evaluate the association of cox-2 expression with the outcome after adjuvant chemotherapy in patients with early breast cancer. Methods: This was planned as a prospective study recruiting consecutive patients receiving adjuvant anthracycline based chemotherapy and with available tissue blocks permitting all immunohistochemical analyses. Cox-2 expression, in addition to other classical biological factors, was evaluated with immunohistochemistry. Disease and patient related, and biological predictors of both overall survival (OAS) and relapse free survival (RFS) were analyzed by Cox regression analysis. Median and mean survival times were calculated according to the Kaplan Meier method. Results: A total of 88 patients were recruited over a period of 24 months. Median age was 45 (29 to 70), and 60% of subjects were premenapausal. Median tumour diameter and number of axillary lymph nodes involved were 2 cm (1 to 6 cm), and 2 (0 to 15), respectively. Median follow up is 74.2 months. Univariate analysis revealed menopausal status and estrogen receptor expression as predictors of OAS, and menopausal status as the correlate of RFS. Multivariate analysis confirmed the independent predictive value of both menopausal status and estrogen receptor expression for OAS (P=0.009, HR=4.18, and P=0.014, HR=0.20, respectively). No multivariate analysis could be performed for RFS. Cox-2 expression was not associated with OAS or RFS (P=0.208, HR=1.92, and P=0.132, HR=1.89, respectively). Interestingly, Cox-2 expression was correlated with Estrogen receptor (ER) and Progesteron receptor (PR) expression (P=0.006, R=-0.303, and P=0.004, R=-0.312, respectively). Conclusions: Cox-2 expression fails to predict clinical outcome of early breast cancer patients treated with adjuvant chemotherapy. However, Cox-2 expression seems to negatively correlate with ER and PR expression. It should be tested in this patient population whether Cox-2 may play a part in hormonal resistance.

Expression of c-erbB-2 and p53 in Breast Carcinoma Patients: Comparison with Traditional Prognostic Factors and Survival

We aimed to determine the correlations between standard clinicopathological factors and expression of c-erbB-2 and p53 proteins, and to investigate the significance of these variables in relapse and disease-free survival (DFS) in breast carcinoma patients. Data from 200 patients who had undergone mastectomy for breast carcinoma were evaluated. Significant correlations were found between c-erbB-2 positivity and high histological grade (grade 3) tumour, p53 positivity and high grade tumour, and age < 60 years and oestrogen receptor negativity. Twenty-six patients (13%) developed a recurrence. Disease relapse was more frequent in patients who had axillary lymph node (ALN) metastasis, high grade tumour, c-erbB-2 positivity and p53 positivity; these variables were also associated with a shorter DFS. The effects of ALN metastasis and p53 positivity were significant. In conclusion, ALN metastasis and p53 positivity were important factors for predicting disease relapse in mastectomy-treated breast carcinoma patients; other clinicopathological criteria and c-erbB-2 positivity were not predictive.
