Úvod: Stanovení strategie léčby karcinomu rekta vyžaduje komplexní a multidisciplinární přístup, na základě kterého je indikována racionální léčba. K primární resekci jsou indikována časná stadia karcinomu rekta, naopak lokálně pokročilé tumory by měly být předléčeny některým z režimů předoperační (chemo)radioterapie. Hlavním cílem této práce bylo zmapovat strategii léčby pacientů s karcinomem rekta v České republice a zejména sledovat výskyt kompletní patologické odpovědi při neoadjuvantní léčbě. Metody: Jde o retrospektivní multicentrickou klinickou studii, která zahrnuje data všech pacientů s karcinomem rekta, kteří byli operováni v zúčastněných centrech v období od 1. 1. 2011 do 31. 12. 2012. Požadovaná data byla zadávána do online registru PATOD C20. Byly stanoveny tři okruhy otázek: 1. charakteristika pracoviště a spolupráce s onkologií; 2. analýza léčby pacientů s karcinomem rekta; 3. detailní analýza skupiny pacientů s kompletní patologickou odpovědí. Analýza byla provedena s ohledem na charakter jednotlivých pracovišť, tj. univerzitní centra s KOC, neuniverzitní centra s KOC a centra mimo KOC. Výsledky: Do studie bylo zařazeno celkem 21 chirurgických pracovišť České republiky, která poskytla data 1860 pacientů. Strategie léčby karcinomu rekta byla určována mezioborovými semináři v 19 centrech (90,5 %). Statisticky významné rozdíly byly zjištěny mezi jednotlivými centry v indikaci neoadjuvantní léčby (p<0,001), provedených resekcí rekta s anastomózou (p=0,048) a resekcí bez anastomózy (p=0,022). Kompletní patologická odpověď byla nalezena celkem u 61 (8,7 %) pacientů. Postižení lymfatických uzlin (ypN+) bylo nalezeno v případě vymizení tumoru ve stěně rekta (ypT0) u celkem 7 (9,7 %) pacientů. Závěr: Studie PATOD prokázala, že péče o karcinom rekta je v ČR velmi heterogenní. Univerzitní a velká centra při KOC, i přes vytvořené nejlepší podmínky, této výhody plně nevyužívají. Klíčová slova: karcinom rekta – neoadjuvantní terapie – chemoradioterapie – kompletní patologická odpověď, Introduction: Deciding on the strategy in rectal cancer´s treatment requires a complex and multidisciplinary approach. The primary rectal resection is indicated in early stages, while locally advanced tumors should be pretreated by one of the modes of neoadjuvant (chemo) radiotherapy. The main goal of this study was to explore the therapeutic strategy in patients with rectal cancer in the Czech Republic. The second aim was to determine the incidence of the pathological complete response after neoadjuvant therapy. Methods: This is a retrospective multicenter clinical study, which includes data from all patients with rectal cancer who were treated at participating centers in the period from 01/01/2011 to 31/12/2012. The required data has been passed into the online registry PATOD C20.Three issues have been set up: 1. Characteristics of the center and cooperation with the oncological department; 2. Characteristics of the treatment of patients with rectal cancer; and 3. Detailed analysis of the group of patients with complete pathological response. The analysis was performed with regard to the nature of individual departments, i.e. departments of surgery in university hospitals with complex oncological centres, departments of surgery within complex oncologic centers, and departments of surgery outside complex oncologic centers Results: In total, 21 departments of surgery in the Czech Republic provided data about 1860 patients with rectal cancer for the study. The treatment strategy for rectal cancer was determined at multidisciplinary seminars at 19 centers (90.5%). Statistically significant differences between the centers were found in the indication for neoadjuvant treatment (p<0.001), rectal resection with anastomosis (p = 0.048), and resection without anastomosis (p = 0.022). Complete pathological response was found in 61 (8.7%) patients. Positivity of mesorectal lymph nodes (ypN+) was found in the case of ypT0 stage in 7 (9.7%) patients. Conclusion: PATOD study showed that therapy of rectal cancer is highly heterogeneous in the Czech Republic. Despite the best conditions provided, university hospitals and large departments within complex oncologic centers do not fully utilize this benefit.

The Purpose of the study: define the indications and contraindications to sphincterpreserving operation in lowerampullar cancer of rectum. The Materials and methods: In coloproctological branch of National Oncological Scientific centre (NOSC) in 20052009 years 142 patients were performed radical operations, 64 (45,1%) patients were performed sphincterpreserving operations abdominoanal resection of rectum (AARR), medium age of patients 59,8 years, beside 78 (54,9%) patients were performed abdomeno perineal extirpation of rectum (APER), medium age 54,2 years. The Results: Studied results of the morphological research of removed preparation by histological structure of tumors and by form of the growing, depending on locations of the tumors on toothed line. The remote postoperative results studied beside 51 (79,7%) patient with AARR and beside 63 (80,1%) patients with APER. The Findings: sphincterpreserving operations (SPO) of the rectum can be the operation of the choice in treatment of high differentiated adenocarcinoma (HDA) and medium differentiated adenocarcinoma (MDA) in stages T23 in localization of the lower pole of tumors, not below 1 centimeter of toothed line (TL) and carries combined character, in location of the lower edge of tumors on toothed line in patients with HDA MDA in 4% and 2,2% cases are shown that completing intrasphincternal resections of rectum, in connection with particular aggressiveness LDA question about choice of the method of the treatment under their localizations directly on TL must be solved in favour of complete APER, in exophytic tumor located onto and above TL is indication for sphincterpreserving operation in type of AARR, indices recurrencefree and not metastatic period, oneyear deathrate, threeyear survivability after SPO at inferior ampular cancer of rectum has not an essential distinction from results after APER., A.

Aim of investigation: to study immediate and remote results of standard and extended lymphodissection in patients with rectal cancer. Material and methods: 132 patients with rectal cancer were performed radical surgery with lymphodissection in D2 and D3 volume according to a height of tumor location. In immediate postoperated period there were noted complications in 4 patients that made up 3,03%. Observation time was 5 years. Tumor recurrence was reported in 5 patients (3,8%). In remote period metastases were revealed in 8 patients (6,6%). 5year total survival rate was 78,5±4,2% at stage II. 5year total survival rate was 56,4±3,7% at stage III. Comparing the results of standard and extended lymphodissection it was noted statistically authentic increase of 5 year survival rate in patients at stage III. Obtained data allow to come to the conclusion about reasonability of performance of different variants of lymphodissection for patients with rectal cancer at stages II and III., Navruzov S.
