21 april 2021: Ik heb dit artikel ook hier geplaatst omdat dit vormen van huidkanker betreft. 

In deze tienjarige studie is de ablatietechniek PDT - Foto Dynamische Therapie ook toegepast bij vormen van huidkanker - basaal carcinoom. Klik op de volgende PDF: paper JCT Melanoma PDT+surgery met ook uitstekende resultaten zoals u kunt lezen. Wij hebben nog steeds contact met Andrei Reshetnickov. Mocht u interesse hebben dan kunnen we u wel in contact met hem brengen. 

3 juni 2018: deze studie: Melanoma: Surgery Subsequent to PDT—Is It Worth Doing? A 10-Year Pilot Trial Using Chlorin-Type Photosensitizer Bremachlorin®

laat zien dat wanneer de fotosensitizer bremachlorin (vroeger radachlorin  geheten) gebruikt wordt 1 dag vantevoren en tijdens de operatie bij de PDT - Foto Dynamische Therapie naast de operatie van een kwaadaardige moedervlek - melanoom de kansen op een recidief sterk vermindert en de overall overleving sterk verbetert. In deze kleinschalige gerandomiseerde studie bij totaal 49 patiënten (24 vs 25) bleek op 5 jaar iedereen uit de chirurgie + PDT groep nog te leven versus slechts 9 uit 24 patienten uit de groep die alleen chirurgie kregen. De PDT met bremachlorin blijkt dus uitstekend te werken met ook minder bijwerkingen en littekens.

Zie ook de patientenverhalen van Karen (borstkanker) en meneer A (prostaatkanker) die begin jaren 2000 naar Ierland (dr. Carmody) en Duitsland (Hufeland kliniek) gingen voor hun kanker te behandelen met PDT met radachlorin.

Uit het abstract: 


Figure 1. (a) Melanoma of the skin before PDT with photosensitizer Bremachlorin in a combination with surgery. (b) Melanoma after removal: the depth of 662-nm-laser light penetration and corresponding infiltrate are well seen to be around 6 mm.


Figure 2. (a) A 80-year-old patient having melanoma of the skin with a 30-year backgroung of Dubreuilh’s melanosis. (b) In 1 year after PDT combined with surgical resection and a plastic operation. Five year cancer free follow-up.

Hexvix, Photofrin II) PDT owing to better pharmaceutical, spectral, pharmacokinetic, toxicological, and energy performance of the former.

By the present study we have shown that combining surgery with PDT performed prior to resection the efficiency of the former may go up more than twice. The obligatory condition for such a rise in the effect seems to be using the 2nd and 3rd generation PSs with effective depth of necrosis exceeding 3 mm, invasion level not more than 3, and absence of local and distant metastases.

Bremachlorin®, also known as “Radachlorin®” and Photochlorin, a composition of 3 chlorophyll a derivatives in an aqueous solution [1], was initially introduced into the Russian and South Korean Pharmacopoeias with the corresponding marketing authorizations received in 2006 and 2008, on the basal cell skin carcinoma PDT protocol. Phase I-II clinical trials led in 2002-2005 showed no side effects, a good tolerability by patients and a high clinical anti-tumor efficacy. Further studies described in the present paper were fulfilled in accordance with a skin melanoma PDT + surgery combined technique protocol in 2006-2016. Resulting from the present trial, up to the 100% complete responses were achieved after resection and plastic surgery following PDT, with no melanoma regrowth or metastases during 5 and 10-year observation periods. Conducting PDT one day prior to tumor dissection can guarantee to meet the ablastics principles at the subsequent surgery. At the same time, the PDT + surgery protocol can allow for dissecting the tumor with less distance from its edge, which seems to be important for the face localizations of tumors.
