This retrospective analysis intends to evaluate by histeroscopy the endometrial findings in a group of 63 patients in post-menopausal treated with tamoxifen for breast cancer. Our patients assumed tamoxifen for a different period between 6 and 120 months. Patients have been divided in two groups: I) patients undergoing hysteroscopy because of some clinical symptoms; II) patients who undergoing hysteroscopy as a routine examination. The most important observation of this work is the correlation between the presence of negative endometrium and low risk hyperplasia (LRH) associated to: symptomatology and duration of therapy. In the group of asymptomatic patients the LRH is found only after 3 years of treatment, while in the group of symptomatic patients, LRH is present within the first two years of treatment; beyond this period high risk hyperplasia (HRH) and endometrial carcinoma have been diagnosed. We also observed a higher incidence of endometrial polyps in this population than among the non treated group and among the symptomatic patients. From these data we conclude that hysteroscopy follow-up has to be performed in the group of patients treated with tamoxifen and that it would be necessary to have a hysteroscopy before the beginning of therapy and that this one has to be repeated once a year through the treatment. Obviously the symptomatic patients have to undergo hysteroscopy as soon as possible as a higher incidence of HRH and endometrial carcinoma has been detected in this group of patients.

66 consecutive patients with a tumor confined to the cervical esophagus underwent surgical resection. The comparison between clinical and pathological TNM stage showed a clinical understaging in 30 patients. 25 of the 56 patients who had undergone curative resection had lymph node metastases: positive mediastinal and abdominal nodes were found in 8 (32%) and 0 cases, respectively. The mean survival after curative resection of the 10 evaluable patients with metastatic periesophageal, recurrent and/or paratracheal nodes was 22.4 months; of the 6 evaluable patients with positive mediastinal nodes it was 10.3 months; and of the 5 patients with positive deep latero-cervical nodes it was 5.8 months. The 2-year actuarial survival after curative resection (in the 53 operative survivors) was as follows (according to pathologic TNM staging): Stage I (n = 3) 100%, Stage IIA (n = 17) 30%, Stage IIB (n = 3) 33%, and Stage III (n = 30) 22%. The exact location of neoplastic recurrence after curative resection was documented in 13 cases; it was in the neck in 8 cases (61%); both neck and at a distance in 3 cases (23%) and only at a distance in 2 (16%). The clinical TNM staging of cervical esophageal cancer was not in agreement with the pathological findings in nearly 50% of the cases and is, therefore, inaccurate and unreliable both for therapeutic decision-making and for prognostic evaluations. Endoscopic ultrasound, which was not used in most of the patients studied here, may improve the accuracy of clinical TNM staging. The N classification, which defines only the cervical nodes as regional nodes, appears to be arbitrary since the pathological staging showed metastatic mediastinal nodes in 32% of the N + cases, with a survival comparable to that of patients with metastatic nodes only in the neck. The prognostic value of pathological TNM staging was not confirmed in the present study since only Stage I patients had a significantly better prognosis than patients in the other stages. This may be due to the small number of patients considered or to lymph node understaging caused by the fact that most patients did not undergo mediastinal lymphadenectomy through a thoracotomy or a sternum splitting.

Between 1975 and 1988 we observed 169 patients with carcinoma of the cervical esophagus, 85 a carcinoma involving the hypopharynx and the cervical esophagus, and 27 patients with a carcinoma of the cervical esophageal region arose after laryngectomy for laryngeal cancer. The mean age was 57.5 years (range 41-73). 167 patients underwent surgical exploration (operability rate 59.5%) and in 152 cases the tumor was resected (resectability rate 91.1%). The resection was complete in 129 patients (84.9%) and palliative in 23 (14.1%). In 33 cases of laryngo-pharyngo-cervical segmentary esophagectomy with free intestinal loop transplantation was performed with an operative mortality of 6.1%. 101 patients underwent laryngo-pharyngo-total esophagectomy and the digestive tract was reconstructed by means of pharyngo-gastrostomy and pharyngo-colostomy in 85 and 16 cases, with an operative mortality of 12.9% and 18.3%, respectively. Total esophagectomy without laryngectomy was performed in 18 patients with a carcinoma of the distal cervical esophagus refusing laryngectomy with an hospital mortality of 5.5%. The overall 5-year actuarial survival, excluding the operative mortality, was 15.8%. After complete resection, better results were recorded with patients operated for carcinoma of the hypopharynx than with patients with carcinoma of the cervical esophagus: the 2-year and 5-year actuarial survival was 59% vs 26% and 43% vs 17%, respectively. No patient undergoing palliative resection was alive at the 3-year interval.(ABSTRACT TRUNCATED AT 250 WORDS)
