A retrospective analysis was performed on 410 patients with nasopharyngeal carcinoma of squamous or undifferentiated histotype. All patients were classified according to the classification of the American Joint Committee for Cancer Staging and End-Results Reporting (AJC) and to that of the International Union Against Cancer (UICC, Geneva, 1978). The following prognostic factors were investigated by means of a Weibull multiple regression model: sex, age, histology, primary tumor extent, and nodal metastasis extent. With the exception of sex, all factors significantly influenced survival. With regards to nodal extent, only the level of the involved nodes was a significant variable. Both AJC and UICC classifications, when applied to the entire series of patients, appeared to be unsatisfactory. The authors propose an alternative classification based on a prognostic scoring system directly derived from the Weibull model.

Psychosocial adjustment of patients surgically treated for head and neck cancer.

Sixty-six patients, surgically treated for head and neck cancer and free of disease, were interviewed at the outpatient clinic from 6 months to 8 years after surgery. The patients were divided by the physician into two groups, according to the patients' degree of disfigurement, i.e., minor (24 patients, 36%, minor disfigurement group = MDG) or extensive (42 patients, 64%, extensive disfigurement group = EDG). Subsequently, the patients were interviewed with close-ended questions. The following subjective aspects were assessed: self-image; relationship with the partner, family, and friends; and the overall impact of the therapy. The results of the study showed a significantly higher impact in the EDG versus the MDG as regards a changed self-image (57% vs 25%, P less than 0.05), a worsened relationship with the partner (27% vs 0%, P less than 0.05), a reduced sexuality (74% vs 39%, P less than 0.01), and an increased social isolation (36% vs 12%, P less than 0.05). On the whole, 18% of the subjects stated that the disadvantages of therapy outweighed the advantages, and 30% fell that the difficulties encountered were "too harsh." In such cases, the opportunity of setting up a rehabilitation program offering psychosocial support should be considered.

Salvage surgery of cervical recurrences after neck dissection or radiotherapy.

A series of 113 patients operated on in the period 1980-1989 for a neck recurrence from a head and neck cancer was studied. All patients had no other evidence of disease. The male/female ratio was 93/20, and the median age was 58 years (range 28-87). Previous treatment consisted of surgery (SG) +/- radiotherapy (RT) in 81 patients (SG group) and only RT in 32 (RT group): 59 cases presented a relapse in the treated neck and 54 in the contralateral side. All but one contralateral recurrences were in the SG group. Ten patients were lost to follow-up. The observed 5-year survival rate of the whole series was 29.2% (95% confidence interval, 0%-38%). Considering patients with ipsilateral recurrences, the 5-year disease-free survival rate was 38.7% (95% c.i., 28.7%-48.7%) and 27% (95% c.i., 18%-36%) for the SG and the RT group, respectively. The 5-year disease-free survival rate after SG for contralateral recurrences was 38.8% (95% c.i., 23.8%-53.8%). Dimension and mobility of the neck nodes were the only demonstrable prognostic factors.

Surgery versus combined therapies for cancer of the anterior floor of the mouth.

We report the results of treatment in a consecutive series of 75 patients operated on at the Istituto Nazionale Tumori of Milan, from January 1965 to December 1979, for cancer of the anterior floor of the mouth. Most of the tumors were advanced: 39 were treated with simple resection, and 36 underwent combined treatment, consisting of surgery associated with either chemotherapy or surgery. Three- and five-year observed survival rates of the whole series were good (41% and 25%, respectively), considering the tumor stage of these patients, but the determined survival rates were particularly high (56% and 46%, respectively). No real advantage was found in the use of multiple planned sequential therapies over surgery alone, and deaths from intercurrent diseases seemed to be more frequent in the patients who underwent combined therapies. We conclude that for patients in poor general condition, such as those with carcinomas of the anterior floor of the mouth, aggressive and complex treatments should be considered with caution in controlled clinical trials.

Prognostic significance of lymphatic spread in head and neck carcinomas: therapeutic implications.

A series of 618 patients with neck dissections were performed in 455 consecutively admitted patients with head and neck carcinomas at the Istituto Nazionale Tumori, Milan, from 1976 to 1978. Clinical and pathologic node factors were considered in an effort to correlate lymph node involvement with prognosis. Actuarial survival decreased with the increase in the size of nodes, although no significant difference was found for all categories and the prognosis was poor when nodes were greater than 5 cm and/or hypomobile (33%, 5-year survival). The presence of histologically proven neck metastases significantly reduces the 5-year survival, and the presence of distant metastases correlates directly with the pathologic staging of neck nodes.

Restoration of atrial function after atrial fibrillation of different etiological origins.

In order to evaluate atrial function after the restoration of normal sinus rhythm in patients with atrial fibrillation, an echocardiographic study was performed in 60 patients hospitalized for atrial fibrillation that was subsequently converted to sinus rhythm. The study population consisted of 60 patients, 41 males and 19 females, with a mean age of 67 +/- 8 years. In etiological terms, 20 patients had atrial fibrillation with no associated pathology, 20 had an underlying ischemic cardiopathy and 20 had hypertension. The duration of atrial fibrillation varied from 24 h to 6 months. The restoration of sinus rhythm was spontaneous in 20 patients and drug induced in 40. Patients were divided into groups on the basis of the duration of the atrial fibrillation, the etiology of the atrial fibrillation and the size of the atrium. Transmitral Doppler inflow patterns at rest were assessed within 24 h after conversion to sinus rhythm, and 1 week, 1 month and 3 months later. The statistical significance of serial changes in peak A velocity and A wave integral was determined by analysis of variance. Using the peak A wave for atrial filling and the velocity-time integral as the index of atrial mechanical function, the following results were obtained: restoration of atrial mechanical function occurred earlier in hypertensive patients and in patients with atrial fibrillation only than in patients with associated ischemic cardiopathy. Restoration also occurred earlier in the group of patients that had atrial fibrillation for < 24 h and in patients whose left atrium was of normal size. Since the mechanical activity of the left atrium, evaluated as the peak A wave, does not necessarily return immediately after the restoration of sinus rhythm, a follow-up assessment of the contraction of the left atrium is appropriate.

Retrospective comparison of conservative and radical neck dissection in laryngeal cancer.

A retrospective comparison of radical and conservative technique for neck dissection in cancer of the larynx was made, starting from analysis of 98 patients operated on with the conservative procedure (128 cervical neck fields at risk of recurrence) at the Istituto Nazionale Tumori of Milan. Furthermore, a series of 162 patients was selected from more than 500 radical neck dissections performed in the past to set up a series as comparable as possible as far as several parameters were concerned. No significant difference was found between radical and conservative neck dissection with regard to the incidence of recurrences in the operative field, either considering the whole series (2.5% versus 1.6%), or cases with histologically proven metastases (9.4% versus 4.5%). Conservative neck dissection seems as safe as radical neck dissection, at least within the limits set in the present study for the indication of the former procedure, ie, nonsuspect nodes or metastatic mobile nodes not greater than 2.5 cm.

Treatment of cancer of the base of the tongue and glosso-epiglottic region: a multicenter Italian survey. GLOCC Group. Gruppo di Lavoro in Oncologia Cervico Cefalica.

BACKGROUND: The current treatment options for cancer of the base of the tongue and glosso-epiglottic region are surgery, radiotherapy, or a combination of both modalities. Comparisons between different modalities are not common in the literature, and a real standard of treatment has not yet been established. The purpose of our study was to evaluate the results of treatment in a large series of patients from 18 Italian institutions in relation to the main treatment adopted. METHODS: The present study is a retrospective survey. The series was divided into a combined surgery group and a radiotherapy group. The Kaplan-Meier method and the log-rank test were used for survival calculations and comparisons. RESULTS: Eight hundred patients were registered (25.7% stage III and 62% stage IV), 336 in the surgery and 372 in the radiotherapy group. Conventional fractionation was adopted in almost all cases. The five-year overall and disease free survival of the whole series was 32% and 38%, respectively. Survival was slightly better for patients with tumors of the glosso-epiglottic region than for those with a tumor of the base of the tongue. Five-year disease-free survival was 55% for patients treated with surgery +/- radiochemotherapy and 26% for those submitted to radiotherapy alone or in combination with chemotherapy. As far as the total dose and the treatment duration were concerned, only 26% of the patients of the radiotherapy group met the established criteria of adequacy, but in patients with adequate radiation the control rate was better only for small tumors (T1-T2). CONCLUSIONS: The results in patients treated with surgery +/- postoperative radiotherapy were similar to or better than those reported in the best series in the literature. By contrast, the survival rate of irradiated patients was lower than those reported by other centers.
