Cancer during pregnancy appears to have a worse outcome when compared to the results reported in the literature of non-pregnant women with the same conditions. This may be related to the advanced clinical stages we found. Cancer during pregnancy requires specialized attention to improve both fetal and maternal outcomes.
Cervical cancer constitutes a major health problem in Mexico and other developing countries. The purpose of our study was to assess the experience of a comprehensive national oncological reference center on pelvic exenteration for post-radiotherapy recurrent or persistent cervical cancer, describing the prognostic value of time to recurrence, procedure complications, and survival. Medical records from 42 patients with post-radiotherapy recurrent or persistent cervical cancer who underwent a pelvic exenteration with curative purposes from 1984 to 1989 were retrospectively reviewed. Histological diagnoses were squamous cell carcinoma (32 patients), adenosquamous carcinoma (9 patients), and adenocarcinoma (1 patient). Average follow up was of 56.3 mo after the procedure and global survival at 5 yr was 65.8%. Survival for patients with early recurrence was 56.9% vs 78% for patients with late recurrence (p = 0.05). Complications were observed in 65.3% of the cases with a surgical mortality of 4.8%. Pelvic exenteration is a surgical procedure with high morbidity in spite of the recent medical advances. Pelvic exenteration should not be indicated with palliative purposes owing to the high rate of complications. Patients with tumor persistence or early recurrence have a worse prognosis. In well-selected cases, exenteration may provide a survival benefit.
ITIC is excellent to detect macrometastases, however, it fails to detect micrometastases. False negative imprints for macrometastases are mainly due to sampling error. The immediate availability, low cost, high Sp, PPV, preservation of the lymph node for histopathologic examination, avoiding of a second surgery are the major advantages of intraoperative evaluation of SLN.

Breast cancer is the second most frequent tumor in Mexico 30-50% are diagnosed in locally advanced stages requiring neoadjuvant chemotherapy. The overexpression of HER-2/neu has been identified as a chemotherapy response predictor. The objective of our study was to identify response predictive factors to anthracycline-based neoadjuvant chemotherapy in locally advanced breast cancer. Data were collected from clinical records of patients with neoadjuvant anthracycline-based chemotherapy, for clinical stage III breast cancer from 1992 to 1997. Paraffin blocks were reviewed to determine histologic grade, HER-2/neu expression, and ploidy. Patients were divided in two groups: A, 56 cases responding to chemotherapy and, B, 20 nonresponders. Mean age was 50.1 and 45.4 for groups A and B, respectively (OR 7.02, p = 0.004), and those premenopausal were 43% and 70%, respectively (OR 3.1, p = 0.04). Mean tumor size was 5 cm in responders and 8 cm for nonresponders (OR 4, p = 0.02). Clinical stage III-B 16% and 70% for groups A and B (OR 12.2, p = 0.000); tumors were aneuploid in 39% of responders and 18.7% for nonresponders. HER-2 /neu was overexpressed in 64.2% and 50% for groups A and B (OR 3.6, p = 0.06). On multivariate analysis significance was conserved only for age, clinical stage, and size. HER-2/neu lost significance. Age and size were importantly related to tumor response, a higher percentage of HER-2/neu overexpression was observed in responders, without significance due to small sample size. It would be important to study a larger number of patients to obtain more conclusive results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
