[Carcinoma of the rectum. Considerations on diagnosis and therapy]. / Il carcinoma del retto. Considerazioni in tema di diagnosi e terapia.

In this review the authors after an introduction on the risk factors, the symptoms and diagnostic aspects of rectal carcinoma, show the different surgical techniques, used second the literature and personal experience on 37 cases for the upper, middle and lower neoplastic lesions of the rectum.

[Soft-tissue sarcomas of the limbs at high risk of malignity. Current role of surgery and conservative treatment]. / Sarcomi ad alto rischio di malignità dei tessuti molli degli arti. Ruolo attuale della chirurgia e trattamento conservativo.

The authors discuss the role of surgical treatment in patients with highly malignant soft tissue sarcomas in the limbs. A careful analysis is made of different therapies on the basis of the results obtained by the authors and those reported in the literature. The anatomic classification of lesions is based on functional anatomic compartments, defined as intra- or extracompartmental. If a lesion was within an intrafascial compartment, all the muscles with intact fascial sheaths have up till now been removed "en bloc" to obtain radical margins. Many authors now think that all manifest disease be removed with a generous soft tissue margin on all sides to ensure adequate local treatment. Amputation has commonly been performed for extracompartmental lesions, but a multinodal treatment programme, including limb-sparing resection and tumour-bed radiation, should now be considered if possible in the management of these tumours.
