Description

Invenţia se referă la medicină, în special la oncologia glandei mamare şi poate fi utilizată pentru tratamentul diferenţiat al carcinomului ductal in situ neivaziv al glandei mamare. The invention relates to medicine, especially to mammary gland oncology and can be used for the differentiated treatment of non-invasive ductal carcinoma in situ of the mammary gland.

Este cunoscută metoda de tratament pentru carcinomul ductal in situ (CDIS), care constă în efectuarea mastectomiei cu radioterapie în perioada postoperatorie. Multicentricitatea adevărată a CDIS s-a dovedit a fi foarte rară. Dat fiind faptul că CDIS nu reprezintă o singură entitate independentă, ci un grup de tumori heterogene, iar fiece caz are anumite particularităţi, ce trebuie luate în consideraţie la alegerea tratamentului, este evident că o singură metodă nu va fi potrivită pentru toate formele de CDIS sau pentru toate pacientele [1]. The treatment method for ductal carcinoma in situ (DCIS) is known, which consists in performing mastectomy with radiotherapy in the postoperative period. True multicentricity of CDIS has been shown to be very rare. Given the fact that CDIS does not represent a single independent entity, but a group of heterogeneous tumors, and each case has certain particularities, which must be taken into account when choosing the treatment, it is obvious that a single method will not be suitable for all forms of CDIS or for all patients [1].

Dezavantajele metodei cunoscute constau în aceea că nu toate formele de carcinom ductal necesită efectuarea mastectomiei, care provoacă dereglări estetice şi psihice la pacientele tinere. The disadvantages of the known method are that not all forms of ductal carcinoma require mastectomy, which causes aesthetic and psychological disorders in young patients.

Problema pe care o rezolvă invenţia constă în elaborarea unei metode de tratament diferenţiat al carcinomului neinvaziv ductal in situ al glandei mamare pentru tratarea eficientă a fiecărei forme de cancer în parte, pentru a micşora numărul de recidive în formele cu o rată înaltă de apariţie a recidivelor, pentru un tratament cosmetic eficient în unele forme care permit păstrarea organului, pentru eficientizarea triajului femeilor primar stabilite cu carcinom neinvaziv pentru un tratament eficient şi pentru micşorarea cheltuielilor şi a timpului pentru investigaţii suplimentare, ceea ce duce la micşorarea termenului de spitalizare. The problem that the invention solves consists in developing a method of differentiated treatment of non-invasive ductal carcinoma in situ of the mammary gland for the effective treatment of each form of cancer separately, in order to reduce the number of recurrences in the forms with a high rate of occurrence of recurrences , for an effective cosmetic treatment in some forms that allow the preservation of the organ, for streamlining the triage of primary women diagnosed with non-invasive carcinoma for an effective treatment and for reducing the expenses and time for additional investigations, which leads to the reduction of the hospitalization period.

Esenţa invenţiei constă în aceea că se determină morfologic prezenţa de comedocarcinom sau de necomedocarcinom şi se efectuează examenul mamografic, unde se determină prezenţa unui singur focar, sau forma multifocală cu focare în acelaşi cadran cu o distanţă de 4…5 cm între ele, sau forma multicentrică cu focare în diferite cadrane sau cu o distanţă mai mare de 5 cm între ele, şi în cazul comedocarcinomului cu un singur focar se efectuează rezecţie sectorială cu radioterapie în perioada postoperatorie, în cazul comedocarcinomului multifocal se efectuează mastectomie cu radioterapie în perioada postoperatorie, în cazul comedocarcinomului multicentric se efectuează mastectomie cu radioterapie şi hormonoterapie în perioada postoperatorie; în cazul necomedocarcinomului cu un singur focar se efectuează rezecţie sectorială, în cazul necomedocarcinomului multifocal se efectuează rezecţie sectorială cu radioterapie în perioada postoperatorie şi în cazul necomedocarcinomului multicentric se efectuează mastectomie. The essence of the invention is that the morphological presence of comedocarcinoma or non-comedocarcinoma is determined and the mammographic examination is performed, where the presence of a single focus is determined, or the multifocal form with foci in the same quadrant with a distance of 4...5 cm between them, or the form multicentric with foci in different quadrants or with a distance greater than 5 cm between them, and in the case of comedocarcinoma with a single focus, sectoral resection with radiotherapy is performed in the postoperative period, in the case of multifocal comedocarcinoma, mastectomy is performed with radiotherapy in the postoperative period, in in the case of multicentric comedocarcinoma, mastectomy with radiotherapy and hormone therapy is performed in the postoperative period; in the case of noncomedocarcinoma with a single focus, sectorial resection is performed, in the case of multifocal noncomedocarcinoma, sectorial resection is performed with radiotherapy in the postoperative period, and in the case of multicentric noncomedocarcinoma, mastectomy is performed.

Rezultatul invenţiei constă în eficientizarea tratamentului pentru fiecare formă de carcinom neinvaziv ductal in situ, micşorarea numărului de recidive în formele cu o rată înaltă de apariţie a recidivelor, efectuarea unui tratament cosmetic eficient în unele forme care permit păstrarea organului, eficientizarea triajului femeilor primar stabilite cu carcinom neinvaziv cu efectuarea tratamentului eficient şi micşorarea cheltuielilor şi a timpului pentru investigaţii suplimentare, ceea ce duce la micşorarea termenului de spitalizare. The result of the invention consists in making the treatment more efficient for each form of non-invasive ductal carcinoma in situ, reducing the number of recurrences in the forms with a high rate of occurrence of recurrences, performing an effective cosmetic treatment in some forms that allow the preservation of the organ, making the triage of primary women established with non-invasive carcinoma with efficient treatment and reduction of expenses and time for additional investigations, which leads to a reduction of the hospitalization period.

Avantajele prezentei invenţii constau în determinarea rapidă a tacticii de tratament a fiecărei forme de carcinom neinvaziv ductal in situ, ceea ce duce la micşorarea numărului de recidive în formele cu o rată înaltă de apariţie a recidivelor, pentru unele forme care permit păstrarea organului se efectuează un tratament cosmetic eficient, efectuarea unui triaj eficient al femeilor primar stabilite cu carcinom neinvaziv cu stabilirea rapidă a tacticii de tratament şi micşorarea cheltuielilor şi a timpului necesar pentru investigaţii suplimentare, ceea ce duce la micşorarea termenului de spitalizare. The advantages of the present invention consist in the rapid determination of the treatment tactics of each form of non-invasive ductal carcinoma in situ, which leads to the reduction of the number of recurrences in the forms with a high rate of occurrence of recurrences, for some forms that allow the preservation of the organ, a effective cosmetic treatment, performing an effective triage of primary women established with non-invasive carcinoma with the rapid establishment of treatment tactics and the reduction of expenses and the time required for additional investigations, which leads to the reduction of the hospitalization period.

Carcinomul ductal in situ CDIS (carcinom intracanalicular, carcinom intraductal) este proliferarea celulelor maligne în interiorul ducturilor glandei mamare fără afectarea membranei bazale. CDIS este o patologie destul de heterogenă, care constă din leziuni proliferative caracterizate prin atipii celulare de la minime la majore şi aspecte arhitecturale foarte variate. După clasificarea europeană au fost diferenţiate trei categorii de CDIS: puţin diferenţiat, moderat diferenţiat şi bine diferenţiat. Ductal carcinoma in situ CDIS (intracanalicular carcinoma, intraductal carcinoma) is the proliferation of malignant cells inside the ducts of the mammary gland without damage to the basement membrane. CDIS is a rather heterogeneous pathology, which consists of proliferative lesions characterized by minimal to major cellular atypia and very varied architectural aspects. According to the European classification, three categories of CDIS were differentiated: slightly differentiated, moderately differentiated and well differentiated.

Din punct de vedere morfologic avem două tipuri de bază de CDIS: From a morphological point of view, we have two basic types of CDIS:

I - comedocarcinom (cu evoluţie nefavorabilă), I - comedocarcinoma (with unfavorable evolution),

II - necomedocarcinom (cu evoluţie favorabilă). II - non-comedocarcinoma (with favorable evolution).

Subtipuri: Subtypes:

1) micropapilar, 1) micropapillary,

2) papilar, 2) papillary,

3) solid, 3) solid,

4) cribriform. 4) cribriform.

Aceste forme rar se întâlnesc de sine stătător, de obicei sunt prezente minimum 2 subtipuri. Cea mai frecventă formă histologică este comedocarcinomul. These forms rarely occur alone, usually at least 2 subtypes are present. The most common histological form is comedocarcinoma.

Particularitatea comună a tuturor tipurilor morfologice este proliferarea celulelor epiteliale maligne în limita lumenului ducturilor fără invazie în stroma glandei mamare. Tipul comedo- are un aspect citologic mai malign, corespunde cu o necroză centrală ductală, care este prezentă în mai mult de jumătate de canale afectate, iar în 50% afectează un singur duct. The common feature of all morphological types is the proliferation of malignant epithelial cells within the lumen of the ducts without invasion into the stroma of the mammary gland. The comedo-type has a more malignant cytological appearance, corresponds to a central ductal necrosis, which is present in more than half of the affected ducts, and in 50% it affects only one duct.

Metoda se efectuează în modul următor. The method is performed as follows.

La pacientele cu suspecţii de carcinom neinvaziv in situ se determină morfologic prezenţa de comedocarcinom sau de necomedocarcinom şi se efectuează examenul mamografic, la care se determină prezenţa unui singur focar, sau forma multifocală cu focare în acelaşi cadran cu o distanţă de 4…5 cm între ele, sau forma multicentrică cu focare în diferite cadrane sau cu o distanţă mai mare de 5 cm între ele, şi în cazul comedocarcinomului cu un singur focar se efectuează rezecţie sectorială cu radioterapie în perioada postoperatorie, în cazul comedocarcinomului multifocal se efectuează mastectomie cu radioterapie în perioada postoperatorie, în cazul comedocarcinomului multicentric se efectuează mastectomie cu radioterapie şi hormonoterapie în perioada postoperatorie; în cazul necomedocarcinomului cu un singur focar se efectuează rezecţie sectorială, în cazul necomedocarcinomului multifocal se efectuează rezecţie sectorială cu radioterapie în perioada postoperatorie şi în cazul necomedocarcinomului multicentric se efectuează mastectomie. In patients with suspected non-invasive carcinoma in situ, the presence of comedocarcinoma or non-comedocarcinoma is determined morphologically and a mammographic examination is performed, in which the presence of a single focus is determined, or the multifocal form with foci in the same quadrant with a distance of 4...5 cm between them, or the multicentric form with foci in different quadrants or with a distance greater than 5 cm between them, and in the case of comedocarcinoma with a single focus, sectoral resection with radiotherapy is performed in the postoperative period, in the case of multifocal comedocarcinoma, mastectomy is performed with radiotherapy in the postoperative period, in the case of multicentric comedocarcinoma, mastectomy with radiotherapy and hormone therapy is performed in the postoperative period; in the case of noncomedocarcinoma with a single focus, sectorial resection is performed, in the case of multifocal noncomedocarcinoma, sectorial resection is performed with radiotherapy in the postoperative period, and in the case of multicentric noncomedocarcinoma, mastectomy is performed.

Radioterapia se efectuează în doză de 45...50 Gy pe parcursul a 5...6 săptămâni (câte 8 Gy în săptămână). Radiotherapy is performed in a dose of 45...50 Gy during 5...6 weeks (8 Gy per week).

Pentru efectuarea hormonoterapiei în formele necesare în perioada postoperatorie se utilizează Tamoxifen. Tamoxifen is used to carry out hormone therapy in the necessary forms in the postoperative period.
