Abstract. Almost half of prostate men cancer, the disease is benign and not life threatening. However, some patients with aggressive tumors have manifestations that can lead to death if not treated. Now the problem concerns to predict the nature of its course. This will prevent useless severe treatment when most patients the tumor can be controlled minimal therapeutic intervention or even just to keep the patient under regular diagnostic control. At present there are real possibilities to confidently enough differentiate the cases where a radical medical aid to the patient is needed and where either only minimal therapeutic support or even just regular periodic examinations and consultations would suffice. What is respectfully acknowledged at major meetings and in editorials is not being applied to patients. The explanations are complex and rooted in a conflict between knowledge and belief with disturbing undertones of economic self-interest. It is time to practice conscience-based medicine.
Keywords: prostate cancer, management of patients, conscience-based medicine.

Реферат. Майже у половини хворих на рак простати, хвороба протікає доброякісно і не загрожує життю. Але у деяких пацієнтів пухлини бувають з агресивними проявами і можуть призвести до смерті,якщо не лікуються. Таким чином, наразі ставиться проблема прогнозувати характер її перебігу. Це дасть можливість запобігти марного тяжкого лікування у випадках, коли у більшості хворих пухлину можна контролювати мінімальним терапевтичним втручанням або навіть вести хворого лише під регулярним діагностичним контролем. Наразі існують реальні можливості достатньо впевнено диференціювати випадки захворювання, коли не обхідна радикальна лікувальна допомога хворому від тих, що потребують або мінімальну терапевтичну підтримку, або ж лише регулярний періодичний огляд і консультацію. Але те, що з повагою визнано на великих нарадах та в редакційних статтях, не стало повсякденною клінічною реальністю. Поясненняє складним і йде корінням у конфлікт між знанням і вірою з тривожним відтінком економічних інтересів. Настав час медицини, заснованої на сумлінні.
Ключові слова: рак простати, ведення хворого, сумлінна медицина
МЕДИЦИНА ОСНОВАННАЯ НА СОВЕСТИ: НОВЫЕ ПОДХОДЫ К ВЕДЕНИЮ БОЛЬНЫХ РАКОМ ПРОСТАТЫ

Реферат. Примерно у половины заболевших раком простаты болезнь протекает доброкачественно и не угрожает жизни. Но у некоторых пациентов опухоль имеет агрессивное течение и может привести к смерти, если не лечить. Следовательно, ныне проблема состоит в прогнозировании характера заболевания. Это дает возможность избежать для большинства больных тяжкого лечения, контролируя опухоль только минимальными средствами, или даже ведя больного лишь под регулярным активным наблюдением. Ныне существуют возможности достаточно уверенно дифференцировать случаи заболевания, когда действительно не обходима радикальная лечебная помощь больному, от тех, когда нужна минимальная терапевтическая поддержка или даже всего лишь регулярное периодическое обследование и консультации. Тем не менее, то, что признано на широких совещаниях специалистов и в редакционных статьях, не стало широкой клинической реальностью. Найти объяснение этому явлению сложно, и уходит оно корнями, вероятно, в конфликт между знанием и верой с тревожным оттенком экономических интересов. Пришло время медицины совести.
Ключевые слова: рак простаты, ведение больного, основанная на совести медицина.
