[Study of the retroperitoneal lymphatic spread of müllerian ovarian carcinoma, using lymphography].

From January 1973 to May 1974, 117 patients with ovarian carcinomas were evaluated with lymphography. The tumors were staged and classified histopathologically according to FIGO (1971). Considering all cases, lymphography showed nodal metastases in 44 patients (38%). Lymphography was positive in 36% of serous cystoadenocarcinomas, in 26% of mucinous cystoadenocarcinomas, in 15% of endometrioid carcinomas and in 36% of unclassified carcinomas. Of the 10 cases not identified by cell type, lymphography was positive in 40% of cases. In 68% of cases bilateral involvement was found. The site of metastatic nodes was in 32% of cases only in the iliac chains were both involved. Considering the single node chains we found 36% of para-aortic, 27% of common iliac, 35% of external iliac and 2% of inguinal involvement. Metastases were observed, regardless of histological type, in 25% of cases in stage III, 62% iin stage IV, 54% in recurrences and only in 5% of cases in stage I. Therefore the lymphatic spread seems to occur in more advanced stages and in recurrences. In 28 of 117 patients node biopsy was performed. Histological-lymphographic correlation was correct in 7/7 positive cases and in 19/21 negative cases (93%). These results show that lymphography is a reliable tool in the evaluation of ovarian cancer.

Bone marrow stromal damage after chemo/radiotherapy: occurrence, consequences and possibilities of treatment.

High dose chemotherapy (CT) followed by bone marrow transplant (BMT) is increasingly used for the treatment of both hematological and solid neoplasms, but an understanding of its late consequences on the marrow microenvironment is still only at its beginning. It is in fact known that marrow stroma is damaged by high-dose cytotoxic therapy and by radiation exposure. However little is known on the extent of this damage and on the self-repair ability of the stroma. The damage of the stromal microenvironment affects the long-term stem cell engraftment and the maintenance of hemopoietic functions. Furthermore, marrow stroma also represents a progenitor compartment for endosteal osteoblasts, and therefore its damage implies alterations of bone metabolism. Indeed, osteoporosis has recently been recognized as a consequence, of BMT, but only a few studies have been performed to establish the functional status of the stromal compartment after treatment with cytotoxic drugs with or without total body irradiation (TBI) and its role in post-BMT sequelae.

[Results of radiotherapy in tumors of the rhinopharynx].

Cumulative 5 years survival following radiotherapy for carcinoma of the nasopharynx does not exceed 30 divided by 35%. Better survival rates are reported in patients with primary lesion of limited extent (T1) or without neck lymph node involvement (N0): 5 years survival 50 divided by 60%. Reports from the most recent series and a review of 159 cases treated at National Cancer Institute of Milano indicate the prognostic significance of the histological type. The 5 years survival rate for "well differentiated carcinoma" ranges from 10 to 34%, in comparison with 25 divided by 50% for the "undifferentiated" type. Local recurrence and invasion of the base of the skull are seen more frequently in the "well differentiated" group while the "undifferentiated carcinoma" shows a stronger tendency to distant metastases (30 divided 35%). On the base of these data a more selected therapeutic approach is suggested.
