[The origin of malignant tumors of the upper-airways, the digestion tract and the ear. Organ-resistance and organ-disposition (organotrophy) by the origin of malignant primary tumors (author's transl)].

Carcinomas of the nose, the trachea, the mouth, the esophagus and the middle ear are rarely observed. Those of the larynx and of the bronchial system are more often found. The reason for this cannot be related to differing contacts with carcinogenic substances. The differences in frequence ar dependent on the varied resistance and disposition of the organs involved (Organotrophy, Histotropy). This is comparable to the incidence of epithelial and mesenchymal tumors. The tissues do not only vary in their structure. The differences are found in 1. the velocity of cell regeneration, 2. the ability to repair nucleic acids, 3. the concentration of tissue specific proteins (chalones) inhibiting cell proliferation and tumor growth, 4. the increase of metabolism before and during cancerization, 5. the unspecific mesenchymal reaction, 6. the immunologic response against tumor cells, 7. the reactions on radiotherapy, 8. the affinity of tissue to chemical carcinogenic substances.

[Guideline for gynecological malignant tumors--primary complex therapy in operable stages of malignant tumors of uterus cervix].

OBJECTIVE: Elaboration of guideline for primary treatment of operable cervical cancer. DESIGN: Review, consensus between proposers and opponents. SETTING: Department of Obstetrics and Gynecology, Charles University, Prague, 2nd Medical Faculty and Faculty Hospital Motol. METHOD: A retrospective review of published data, analysis of Czech statistics and consensus between proposers and opponents. RESULTS: Team work is essential in the diagnostic and therapeutic procedure. For the preoperative diagnostic management it is possible to perform magnetic resonance volumometry. For the treatment of early stage cervical cancer it is possible to perform sentinel lymph node mapping (SLNM) by patent blau and 99mTc together with frozen section. SLNM does not substitute systematic pelvic lymphadenectomy. For the treatment of IB2 stage cervical cancer, an alternative for primary surgery or chemoradiotherapy is neoadjuvant chemotherapy, followed by radical surgery. In other topics only minor changes were made from the 1998 guideline. CONCLUSION: The guideline for cervical cancer treatment should represent directions for clinicians and others, who participate in the process of the treatment of cervical cancer. The guidelines include all parts of the process (from diagnosis to follow up). It originated from the consensus between proposers and opponents: we voted about all parts of guideline.

[Guideline for gynecological malignant tumors 2004--primary complex therapy in operable stages of malignant tumors of vulva].

OBJECTIVE: Elaboration of guideline for primary treatment of operable vulvar cancer. DESIGN: Review, consensus between proposers and opponents. SETTING: Department of Obstetrics and Gynecology, 2nd Medical Faculty Charles University and Faculty Hospital Motol, Prague. METHOD: A retrospective review of published data, analysis of Czech statistics and consensus between proposers and opponents. RESULTS: Guideline for the diagnosis remain the same as in the proposal from 1998. We elaborated practically new guideline for surgical treatment. Wide excision or simplex vulvectomy is adequate only for stage la without angioinvasion, free margins have to be 5 mm. Standard surgical procedure is radical vulvectomy with inquinofemoral lymphadenectomy in stage 1a with angioinvasion, 1b and 2. In laterally localised lesions it is possible to perform hemivulvectomy or radical excision with inquinofemoral lymphadenectomy. Free margins have to be more than 8 mm. An alternative procedure in internally high-risk patients is sentinel node detection with radical vulvectomy (hemivulvectomy). Sentinel node detection has to by performed by combined method of blue dye and radiocoloid Tc 99 simultaneously. Bilateral inquinofemoral lymphadenectomy is indicated in case of positive sentinel node. Primary radiotherapy is indicated in higher stages, in stage 3 we can perform an exenteration with the agreement of patient. CONCLUSION: Guideline for the treatment of vulva cancer should be directions for clinicians and others, who participate in the process of treatment of the vulva cancer. Guidelines include all parts of the process (from diagnosis to follow up). All topics of the guidelines were arise from a voting of the proposers and opponents.

[Guideline for gynecological malignant tumors I. Standard--a complex therapy of ovarian epithelial malignant tumors].

OBJECTIVE: Elaboration of guideline for primary and secondary treatment of ovarian cancer. DESIGN: Review, consensus between proposers and opponents. METHOD: A retrospective review of published data, analysis of Czech statistics and consensus between proposers and opponents. RESULTS: We underline importance of comprehensive approach in therapy of ovarian cancer. We notice importance of expert ultrasound and CA 125 level in diagnostic algorithm. Extension of surgery depends on result of frozen section. All departments which want to perform surgery for ovarian resistance must have possibility to do peroperative histopathology. We can perform conservative fertility sparing surgery in patient with wishing of pregnancy and low stage disease. The effort of maximal debulking with radical surgery including lymphadenectomy is the standard procedure. When we diagnose ovarian cancer during laparoscopy, we have to convert on laparotomy procedure. We define the role of the neoadjuvant chemotherapy followed by surgery after 3-4 cycles of chemotherapy. We define adequate surgery treatment, indication for adjuvant chemotherapy and indication for second line therapy. CONCLUSION: Guideline for the treatment of epithelial ovarian cancer should become directions for clinicians and others, who participate in the process of treatment of the ovarian cancer. The guidelines include all parts of the process from diagnosis, treatment to follow up. All topics of the guidelines arose from a voting of the proposers and opponents.
