Between 1979 and 1988, iterative surgery was performed on 13 patients for a germ-cell tumor. Apart from orchidectomy, surgery was not the first modality of treatment. On the other hand, 21 surgical procedures were performed for residual tumoral masses after chemotherapy or recurrences. In one third of the cases, only necrosis of fibrosis was resected. Out of 13 patients, 7 died of tumor; 6 are alive (3 with complete remission). Surgery is always indicated in stage IIA to IV nonseminomatous tumors in case of residual tumoral deposits after chemotherapy. For seminoma, surgery is carried out only for retroperitoneal residues larger than 3 cm in diameter. Surgery is also indicated for persistent pulmonary or mediastinal metastases following chemotherapy. Complete surgical excision of residual masses may be technically difficult but is of prime importance as combined chemotherapy and surgery doubles the complete remission rate in comparison to chemotherapy alone.

With cancer patients, the venous access remains a major problem. It causes phlebitis, venous sclerosis, skin necrosis and sepsis. Its maintenance implies careful nursing and a great dependence for the patient. Arterio-venous fistulas have been abandoned and replaced by Hickman-type subcutaneous indwelling catheters. These have a complication rate, mainly infectious, of about 0.4/100 days. The development of totally implanted catheters diminishes even more this rate and improves the patient's comfort. In this article we report the experience gained from 100 cancer patients equipped with 107 catheters. 31 complications occurred over a total time of 15,421 days, this averages a rate of 0.2 complications/100 days. The respectively rate of thrombosis and infections are of 0.02/100 days each. In 61% of the cases the whole system was functional after management of the complication. This results confirm the excellent tolerance of the system, its minimal rate of complication and its great possibility of reutilization.

In 1986, a prospective study was started in CHUV on the squamous-cell carcinoma of the esophagus treated with a multimodality protocol associating preoperative chemotherapy and surgery. Nineteen patients are currently followed-up. Dysphagia is the main symptom and was found in 16 patients (84%). After chemotherapy, dysphagia disappeared completely in 7 cases (44%), regressed in 7 other cases and worsened in 1 case. Twelve patients were operated on, without operative mortality. Histologically, no tumor was found in one case (5%) after the preoperative treatment. Follow-up is currently too short to draw statistical conclusions. The rationale, advantages and perspectives of the multimodality treatment are presented and compared with different recent series.
