[Supplementary morphological criteria F anf G in the classification of esophageal cancer by the TNM system]. / Dopolnitel'nye morfologicheskie kriterii F i G v klassifikatsii raka pishchevoda po sisteme TNM.

Additional criteria are introduced for the prognosis of esophageal carcinoma: anatomical form of growth (F) and the degree of carcinoma differentiation (G). These conclusions are drawn basing on long-term results of treatment of 302 patients. These additional criteria help to make a proper choice of treatment. The best results may be expected under the following combination--T1P1-2N0M0F1G1, 5-year survival in these patients was 69.8%. Unfavourable results were in the group of radically treated patients with the following combination T3P3N1M0F1-3G3bv, 5-year survival being 7.8% only.

[The late results of the surgical and combined treatment of cancer of the intrathoracic esophagus]. / Otdalennye rezul'taty khirurgicheskogo i kombinirovannogo lecheniia raka vnutrigrudnogo otdela pishchevoda.

An analysis of 392 radical operations on patients with carcinoma of the esophagus has shown that surgical treatment is justified for tumors of not more than 3 cm size, growth to the muscular layer of the esophagus, with tumors having exophytic and ulcerous forms of growth, high degree of differentiation and without metastatic involvement of the regional lymph nodes. Combined (radial and surgical) treatment is justified for any size of the tumor having mixed, ulcerous-infiltrative and diffuse-infiltrative forms of growth, for tumors of medial and low degrees of differentiation.

[Adenogenous cancer of the esophagus]. / Adenogennyi rak pishchevoda.

The authors consider the most promising long-term results to be achieved in treatment of patients with highly differentiated adenocarcinomas, size of the tumor up to 60 cm and growth of the tumor into the muscle level. The prognosis was doubtful in patients after radical operations but having average degree of differentiation of adenocarcinomas, with size more than 60 cm and growth into the whole esophagus wall. The prognosis was unfavorable in patients with poorly differentiated adenocarcinomas. Metastatic involvement of lymph nodes does not make the prognosis worse.

[Metastatic involvement of regional lymph nodes and long-term results of the treatment of patients with cancer of the thoracic part of the esophagus]. / Porazhenie metastazami regionarnykh limfaticheskikh uzlov i otdalennye rezul'taty lecheniia bol'nykh rakom grudnoi chasti pishchevoda.

The patients who underwent the radical operations for cancer of the thoracic esophagus were subdivided into three groups: group 1--patients with no metastatic involvement of the regional lymph nodes (N0); group 2--with enlarged regional lymph nodes because of their hyperplasia, but without metastatic involvement (NX); group 3--with metastatic involvement of the regional lymph nodes (N1). The best results of 5-year survival after radical operation (50.2%) were noted in patients with a tumor size less than 3 cm, infiltration of only muscular layer, high degree of cancer differentiation, without metastatic involvement of regional lymph nodes. In presence of metastases, the 5-year survival was 6.01%. Discovering at operation the enlarged lymph nodes is a poor prognostic sign, 5-year survival of these patients do not exceed 9%.

[The prognostic significance of the anatomical forms of esophageal cancer]. / Prognosticheskoe znachenie anatomicheskikh form raka pishchevoda.

Among the great variety of anatomic patterns of esophageal cancer growth, three basic patterns--exophytic, mixed and endophytic--should be distinguished. Anatomic pattern of growth is one of the basic prognostic criteria for tumor stage assessment. This finding is supported by five-year survival evidence for cases of radical surgery: 58.8 +/- 10% with exophytic form, 16.6 +/- 10%--ulcerative infiltrative and 3.3 +/- 6% with diffuse infiltrative pattern of tumor growth.

[Liposarcoma of the retroperitoneal space]. / Liposarkoma zabriushinnogo prostranstva.

Date of an examination of 60 patients with liposarcomas of the retroperitoneal space aged from 40 to 60 are presented, women comprised 62%, men 38%. Operative treatment was undertaken in 48 patients (96%), radical operation--in 82%, palliative operations--in 14%. Recurrent tumors were revealed in 33 patients (66%), metastases--in 8%. Most frequent recidivations were noted in myxoid liposarcomas. A complete removal of the recurrent tumor was made in 72% of the cases. Out of 50 patients with liposarcomas 54.2% of the patients survived 5 or more years after the operation, in the myxoid variant--72.3%, in polymorphocellular form--23.1%.

[Reoperations in retroperitoneal tumors of non-organic origin]. / Povtornye operatsii pri zabriushinnykh opukholiakh neorgannogo proiskhozhdeniia.

Great, solid and fixed tumors should not always be considered as a reason for refusal of an operative treatment of patients with retroperitoneal tumors of nonorganic origin. Resection of such tumors especially those of benign genesis results in a complete recovery of the patients and their rehabilitation. The appearance of a recurrent retroperitoneal tumor of nonorganic origin should not be regarded as an inoperable condition. The timely diagnosis and operative treatment of patients with recurrences give three times better remote results of the treatment.

[Primary and recurrent retroperitoneal neoplasms of non-organic origin]. / Pervichnye i retsidivnye opukholi zabriushinnogo prostranstva neorgannogo proiskhozhdeniia.

Having analyzed results of the treatment of 216 patients the authors came to a conclusion that recurrencies of tumors, repeat ones included, can not be considered as contraindications for operations. The most favourable results were obtained in the operative treatment of recurrent lymphosarcomas.

[Nonorganic tumors of the retroperitoneal space]. / O neorgannykh opukholiakh zabriushinnogo prostranstva.

The investigation performed gave the impression that only early diagnosis of tumors in the retroperitoneal space of non-organic genesis could give the timely and radical treatment. The authors believe that the dynamic observation, diagnosis and surgical treatment of relapses will give considerably better remote results.
