[Nutritional support in the treatment of gastric cancer].

The investigation involved 307 patients operated on for gastric adenocarcinoma. Nutritional support was given enterally (50), parenterally (98) and by standard methods (159). Enteral nutrition should be recommended because it was followed by relatively higher total protein and serum albumin levels.

[Current principles and methods of radical therapy for locally extensive esophageal and gastroesophageal cancer]. / Sovremennye printsipy i metody radikal'nogo lecheniia mectorasprostranennogo raka pishchevoda i kardioèzofageal'noi zony.

The results of radical surgical and combined treatment of 124 cases of esophageal and cardioesphageal tumors are presented. Extensive local disease (stage III, T2-4N0-2M0) was diagnosed in 113 patients (91.1%). Esophagoectomy with transmediastinal esophagogastroplasty and cervical esophagostomy proved most useful for esophageal tumor, while extensive surgery after Lewis in combination with extirpation or proximal resection of the stomach--for proximal gastric disease involving the esophagus. Combined surgery with resection of adjacent organs was carried out in 50%. Post-operative mortality rates were reduced to 7.1% due to application of effective surgical, anesthetic and intensive care procedures. The 3-year survival rate was 26.5%. Prognosis improved significantly when radiation was used prior to dissection of lymph nodes.

[The quality of medical care given to patients with esophageal cancer in St. Petersburg and the Leningrad region]. / Sostoianie lechebnoi pomoshchi bol'nym rakom pishchevoda v Sankt-Peterburge i Leningradskoi oblasti.

The data on the morbidity, time of diagnosis and results of treatment of esophageal cancer in St. Petersburg and Leningrad Region (1992-1994) were analyzed. The morbidity rates were higher in women than in men, the predominant age being over 60. Morphological verification data were not available in almost half the cases. Stage I-II tumors were detected in 15.7-26.5%. Specialized treatment was given to 25%, combination one-to nearly 2%. To raise the standards of medical aid, it is suggested that measures be taken to ensure stable operation of the Cancer Register, St. Petersburg, and to offer treatment to esophageal cancer patients at specialized medical facilities.

[Pathogenesis of colorectal cancer after resection of various segments of the large bowel]. / K voprosy o patogeneze kolorektal'nogo raka posle rezektsii razlichnykh otdelov tolstoi kishki.

The data on 120 cases of primary multiple cancer of the large bowel and 91 cases of diffuse polyposis are discussed. The development, duration and morphological features of metachronous and primary cancer arising after resection of the bowel varying in type and extent were studied. The results pointed to a high risk of cancer in such cases. The study also pointed to disturbances in the enterohepatic system and bile acid circulation as a factor of carcinogenesis in the bowel.
