RESUMO
We present the clinical and pathological features of two cases of facial Merkel cell carcinoma (MCC) and a critical reappraisal of the literature on this subject. Among patients with this presentation of a rare neoplasm, the disease is very often localized (local or locoregional growth, without distant metastases). Radiotherapy seems to be highly effective in obtaining local control and possibly cure, even when used as the sole treatment method; prompt regression of the neoplastic masses has been observed in both the cases we treated. One of them, and many of those reported in the literature and treated with radiotherapy alone or combined with surgery, achieved long-term survival.

Fifteen cases of chordoma, seen between 1956 and 1990 at the Florence Radiotherapy Department are reported. Twelve of them were treated with radiotherapy and surgery, while one was left untreated. We analyzed the course of the disease in the treated cases, with particular emphasis on the problem of symptom control. The natural history of the disease seemed to be only marginally affected by the treatment and new therapeutic options are strongly needed. While actuarial survival rates at 5 and 10 years were 58% and 35% respectively (owing to the slow growth rate of this neoplasm), 10 years' symptomatic progression-free, symptom-free, and disease-free survival rates were only 25%, 17% and 8% respectively.

The present study was undertaken to investigate the clinico pathologic features of Hodgkin's disease in a series of 114 elderly patients (age greater than 60 yrs), with particular reference to prognosis and treatment. Mixed cellularity (63.2%) was the most frequent histologic subtype. Clinical presentation was characterized by superficial lymphadenopathy (92%) and the presence of general symptoms (40.4%); mediastinal involvement was observed in 16.6% of cases; 17.5% of patients had a primitive infradiaphragmatic presentation. Thirty-eight patients were treated with radiotherapy alone (33.4%), 69 with chemotherapy alone (60.5%), while 7 received combined treatment. Complete remission was obtained in 85 patients (74.6%), 25 of whom relapsed. Elderly patients had an overall 5-year survival rate of 61.8% (considering only disease progression as a cause of death). Proportional-hazard multi variate statistics showed that survival was strongly influenced by the achievement of complete remission (P less than 0.001) and stage (P = 0.011). The achievement of complete remission was also significantly linked to the presence of constitutional symptoms, advanced stage and age greater than 70 yrs, as demonstrated by discriminant statistical analysis. The actuarial incidence of second cancer (28.7% at 15 yrs) was slightly higher than that previously reported in younger patients. Overall, our data indicate that the treatment of elderly patients with Hodgkin's disease should be aimed at achieving a cure, using the same therapeutic modalities commonly employed in younger subjects.

In order to assess whether mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy (CT), which is less expensive and more easily available than radiotherapy (RT), is at least as effective as RT in terms of cure rate and has less iatrogenic damage, 89 consecutive patients with Hodgkin's disease (HD) (pathological stage I-IIA) were randomly allocated to receive mantle plus lumbar bar RT (36-45 Gy) or CT (six courses of MOPP). Forty-five patients were entered in the RT group and 44 in the CT group. The median follow-up was 60 months. Complete remission (CR) was obtained in all patients in the RT group and in 40 of 44 patients in the CT group. Overall survival (OS) and disease-free survival (DFS) were, respectively, 87.2% and 72.7% in the CT group and 93.5% and 74% in the RT group. Survival probability of relapsing patients was 76% for the patients in the RT group and 45% in the CT group. Treatment-related complications were more severe in the CT group as compared with the RT group.

Of 750 patients with stage I, II or III Hodgkin's disease, admitted to the University and Hospital Radiotherapy Divisions, Florence, between 1960 and 1981, 28 (3.7%) had involvement of Waldeyer's ring (WR). In 25 patients there was associated involvement of upper cervical nodes. Other factors associated with WR involvement were age over 55 years, lymphocyte predominant histological sub-type, uninvolved mediastinum, and size of involved upper cervical nodes greater than that of involved lower cervical nodes. These factors help to define indications for prophylactic irradiation of WR.

Pulmonary function tests were performed in 43 patients with Hodgkin's disease before mantle irradiation and at 3, 6, 9, 12 and 15 or more months thereafter. Treatment was given with a telecobalt unit to a total dose of 36 to 42 Gy, the higher dose being reserved for cases with considerable mediastinal involvement. The functional parameters explored included static and dynamic lung volumes, gas exchanges, ventilatory efficiency, and airway resistance. Measured parameters were expressed as a percentage of the pre-treatment value (PTV) in the individual patient. In the whole group, only small variations in the functional indices were observed at 3 to 6 months after mantle irradiation. In patients with normal PTVs a greater variation in static and dynamic volumes was observed at 3 to 6 months after mantle irradiation, with complete recovery thereafter. The gas exchange parameters also showed a similar variation at 3 to 6 months but no recovery was demonstrated in the subsequent examinations. No changes in ventilatory efficiency and airway resistance were observed. In patients with abnormal PTVs, usually presenting large mediastinal adenopathy, all parameters improved after mantle irradiation, and the favourable effect of tumour regression was probably more important than the radiation damage on the pulmonary parenchyma.

Twenty patients with Hodgkin's disease limited to infradiaphragmatic (ID) nodes have been treated at the University and Hospital Radiotherapy Departments in Florence between 1960 and 1978. Clinicopathologic features and treatment modalities of these patients were reviewed and results compared with those of 2 similar series previously published by other authors. With respect to the patients with disease above the diaphragm, the ID presentation occurred more often in males in all the 3 reviewed series; a relative prevalence of the lymphocytic predominance histotype and of an older age was observed in 2 only of the 3 series; laparatomy seems unnecessary in lymphographic-negative patients. The analysis of therapeutic results suggests that inverted Y irradiation is a sufficient treatment when inguinal or lower iliac nodes only are affected; paraortic region and spleen involvement warrant a more radical program including the supradiaphragmatic irradiation or systemic chemotherapy.

The files and the roentgenographic documentation of 624 patients affected by Hodgkin's disease have been reviewed. The presence and location of involved nodes in the different lymph node chains of the mediastinum have been determined and correlated with the distribution of the main anatomoclinic prognostic parameters of the disease. Feminine sex, histology of nodular sclerosis, presence of constitutional symptoms and age younger than 36 were found to be significantly more frequent in patients with mediastinal adenopathies than in patients with a normal mediastinum. Patients with mediastinal adenopathy at presentation were also more likely develop pulmonary involvement as first evidence of new manifestation of disease after the primary treatment. A different probability to be affected by disease was evident among the different lymph node groups in the mediastinum. The involvement of hilar nodes appeared to accompany a more advanced stage of disease and to favour the adjacent lung extension.

A 39-year-old patient with Hodgkin's disease, treated with radiation and chemotherapy, developed an undetected severe cardiopathy that was responsible for a sudden death. Possible causes of this cardiac damage are discussed. The therapeutic success on lymphoma, confirmed by postmortem examination is emphasized.

Sixty-seven patients with nodular sclerosis (Hodgkin's disease stages I and II) have been subclassified according to the cellular composition and the amount of fibrosis. Predominance of mature lymphocytes and rarity of Reed Sternberg cells were associated with less extensive disease at presentation and more favourable outcome. A less definite correlation to the amount of fibrosis was found.
