4. gradul de viabilitate a proiectului:
Una dintre problemele majore cu care se confrunta lumea medicala, este cancerul. Cancerul este considerat ca fiind a doua cauza importanta a
mortalitatii pe intregul glob. In Romania, in ultima decada, s-au inregistrat schimbari majore in structura morbiditatii si mortalitatii populatiei. S-a inregistrat o crestere rapida a numarului tumorilor maligne, acestea reprezentand a doua cauza de deces, imediat dupa afectiunile cardiovasculare. Puternicul impact al cancerului asupra societatii romanesti se regaseste nu numai in numarul mare al deceselor (circa 38 000 pe an, ceea ce reprezinta 13-14% din total) ci si in numarul noilor cazuri inregistrate (circa 45 000 pe an) si al bolnavilor in viata (circa 200 000). Pornind de la aceste date, tratarea cancerului a devenit una dintre prioritatile nationale din domeniul medical.
Avand in vedere toate aceste aspecte, diseminarea la Congrese si alte manifestari stiintifice internationale de profil a rezultatelor si cunostintelor acumulate pe parcursul anilor privind sinteza porfirinelor si utilizarea lor in domeniul terapiei cancerului a fost de o importanta majora, si au fost realizate atat de conducatorul cat si de membrii acestui consortiu. Ca rezultat al activitatilor anterioare, consortiul organizat pentru acest proiect, detine prioritati la scara industriala in domeniul macrociclurilor terapeutice.
Prin acest proiect de cercetare s-a urmarit realizarea de noi sisteme cu caracteristici spectrale de absorbtie in regiunea IR apropiat, la care
sa se investigheze proprietatile fotofizice si fotochimice, studiile propuse a se realiza aduc relevanta pentru procesele de agregare si/sau
transfer de energie prin prisma interactiilor fotosensibilizatori /substrat viu. Posibilitatile de succes ale proiectului pot fi asigurate printr-o buna coordonare a grupelor de cercetare in domeniu. Proiectul propus are in vedere demonstrarea viabilitatii acestei metode de tratare a cancerului si alinierea cercetarii de pe plan national cu cercetarea internationala in domeniu.
Viabilitatea si sansele de succes ale proiectului au avut la baza experienta membrilor echipei, conceptia proiectului, si cooperarea internationala initiata deja. Astfel, proiectul este viabil datorita urmatoarelor considerente:
- Experienta si rezultatele obtinute de INCDCP-ICECHIM in domeniul sintezei porfirinelor/ftalocianinelor, cu aplicatii in terapia fotodinamica a cancerului
- Experienta si rezultatele obtinute de partenerii ICECHIM si INCD Victor Babes in domeniul studiilor de toxicologie in vitro/in vivo in domeniul terapiei fotodinamice
- Experienta si rezultatele obtinute de Spitalul Colentina si Spitalul Stefan Longhin in domeniul studiilor clinice interne si internationale, dintre care unele realizate chiar in domeniul terapiei fotodinamice
- Modul de conceptie si de management performant ale proiectului
- Colaborarea initiata deja intre colectivele partenerilor implicati
- Cooperarea internationala initiata deja de membrii echipelor de cercetare (vezi anexele)
- Aparatura moderna detinuta de partenerii implicati in proiect si metodologia de inalt nivel utilizata (anexa)
- Planificarea judicioasa a termenelor, activitatilor si colectivelor angrenate
- Nucleul complex realizat pe plan national de specialisti in domeniul terapiei fotodinamice, care, prin activitatile desfasurate in cadrul acestui program, a crescut vizibilitatea stiintifica in plan european

6. impactul tehnico-economic şi social estimat la implementarea proiectului
Din punct de vedere economic, terapia fotodinamica a cancerului are avantaje certe vizavi de costul, efcicienta, siguranta si durata terapiei cu citostatice, comparativ cu efectele secundare nedorite ale radioterapiei. In plus, TFD poate veni in completarea actului chirurgical prin localizarea tumorii sau prin interventia la nivelul tumorilor inoperabile sau inabordabile. Terapia fotodinamica se afla in etapele preclinice sau in faze avansate de testare clinica pe plan international si acest proiect creaza o baza de date pentru aplicarea cu costuri reduse in clinicile nationalea unei terapii actuale.
Impact direct
Rezultatele proiectului vor oferi clinicianului date care permit:
- trecerea in fazele de testare clinica 2, 3 si 4 pe un numar crescut de pacienti si patologii dermatologice
- imbunatatirea terapiei antitumorale si respectiv a starii de sanatate a populatiei active si varstnice
- eficientizarea terapiei conduce si la un impact economic direct, reducand costurile terapiei clasice antitumorale
- perspectiva de dezvoltare in continuare a substantelor fotosensibilizante utilizate in TFD a cancerului
- extinderea utilizarii substantelor fotosensibilizante in fotodiagnoza, avand in vedere ca substantele se incarca preponderent in celulele tumorale, comparativ cu cele normale
- elaborarea si realizarea unei metode care sa asigure imbunatatirea tratamentelor individualizate, asigurandu-se cresterea procentului de
rezultate pozitive in tratarea unor forme de cancer
Impact indirect
Impactul asupra mediului stiintific prin:
- crearea unui model experimental aplicabil in testarea diferitelor clase de compusi fotosensibilizanti
- formarea unui nucleu de cercetare aplicativa prin colaborarea stiintifica complexa la nivel regional si national
- posibilitatea intrarii intr-o retea internationala de excelenta in domeniul terapiei fotodinamice, datorita tehnicilor si problemelor stiintifice de mare actualitate abordate
- cresterea vizibilitatii cercetarii romanesti si accelerarea procesului de aliniere la reglementarilor Uniunii Europene
Impactul economic se concretizeaza prin:
- realizarea unor noi substante medicamentoase pentru terapia cancerului;
- realizarea unei noi metode de tratare a cancerului;
- deschiderea unor noi oportunitati de tratament alternativ, care implica producerea de lasere performante, sinteza, in tara noastra, a unor structuri porfirinice cu caracteristici impuse, uniforme, ajustabile care sa conduca la procese biocatalitice de foarte inalta selectivitate;
- realizarea unor economii la bugetul asigurarilor de sanatate prin diminuarea costurilor de tratament si a perioadei de spitalizare, precum si prin diminuarea eforturilor valutare privind importul de medicamente.
Impactul social se concretizeaza prin:
- efecte benefice asupra sanatatii populatiei, prin realizarea unei terapii anti-neoplazice neinvazive, cu efecte secundare minime, realizabila ambulator si cu specificitate mai ridicata in comparatie cu chemo si radioterapia
- recuperare rapida dupa terapie, datorita efectelor secundare minime
Impactul asupra mediului se concretizeaza prin:
- metodele de terapie bazate pe fotosensibilizare indusa nu sunt toxice comparativ cu radioterapia si chimioterapia
- sistemele laser utilizate in cadrul proiectului nu presupun in timpul functionarii sau dupa expirarea duratei de viata a acestora emisia sau crearea de substante poluante si periculase pentru mediu.
