Intercalated chemotherapy and erlotinib for advanced NSCLC : high proportion of complete remissions and prolonged progression-free survival among patients with EGFR activating mutations
Matjaž Zwitter, Karmen Stanič, Mirjana Rajer, Izidor Kern, Martina Vrankar, Natalija Edelbaher, Viljem Kovač, 2014, original scientific article

Abstract: Background. Pharmaco-dynamic separation of cytotoxic and targeted drugs might avoid their mutual antagonistic effect in the treatment of advanced non-small cell lung cancer (NSCLC). Patients and methods. Eligible patients were treatment-naive with stage IIIB or IV NSCLC. In addition, inclusion was limited to never-smokers or light smokers or, after 2010, to patients with activating epidermal growth-factor receptor (EGFR) mutations. Treatment started with 3-weekly cycles of gemcitabine and cisplatin on days 1, 2 and 4 and erlotinib on days 5 to 15. After 4 to 6 cycles, patients continued with erlotinib maintenance. Results. Fifty-three patients were recruited into the trial: 24 prior to 2010 (of whom 9 were later found to be positive for EGFR mutations), and 29 EGFR mutation-positive patients recruited later. Unfavourable prognostic factors included stage IV disease (51 patients - 96%), performance status 2%3 (11 patients - 21%) and brain metastases (15 patients - 28%). Grade 4 toxicity included 2 cases of neutropenia and 4 thrombo-embolic events. The 15 EGFR negative patients had 33% objective response rate, median progression-free survival (PFS) 6.0 months and median survival 7.6 months. Among 38 EGFR positive patients, complete response (CR) or partial response (PR) were seen in 16 (42.1%) and 17 (44.7%) cases, respectively. PET-CT scanning was performed in 30 patients and confirmed CR and PR in 16 (53.3%) and 9 (30.0%) cases, respectively. Median PFS for EGFR mutated patients was 21.2 months and median survival was 32.5 months. Conclusions. While patients with EGFR negative tumors do not benefit from addition of erlotinib, the intercalated schedule appears most promising for those with EGFR activating mutations.

Brain metastases in lung adenocarcinoma : impact of EGFR mutation status on incidence and survival
Karmen Stanič, Matjaž Zwitter, Nina Turnšek, Izidor Kern, Aleksander Sadikov, Tanja Čufer, 2014, original scientific article

Abstract: The brain represents a frequent progression site in lung adenocarcinoma. This study was designed to analyse the association between the epidermal growth factor receptor (EGFR) mutation status and the frequency of brain metastases (BM) and survival in routine clinical practice. Patients and methods. We retrospectively analysed the medical records of 629 patients with adenocarcinoma in Slovenia who were tested for EGFR mutations in order to analyse the cumulative incidence of BM, the time from the diagnosis to the development of BM (TDBM), the time from BM to death (TTD) and the median survival. Results. Out of 629 patients, 168 (27%) had BM, 90 patients already at the time of diagnosis. Additional 78 patients developed BM after a median interval of 14.3 months; 25.8 months in EGFR positive and 11.8 months in EGFR negative patients, respectively (p = 0.002). EGFR mutations were present in 47 (28%) patients with BM. The curves for cumulative incidence of BM in EGFR positive and negative patients demonstrate a trend for a higher incidence of BM in EGFR mutant patients at diagnosis (19% vs. 13%, p = 0.078), but no difference later during the course of the disease. The patients with BM at diagnosis had a statistically longer TTD (7.3 months) than patients who developed BM later (3.1 months). The TTD in EGFR positive patients with BM at diagnosis was longer than in EGFR negative patients (12.6 vs. 6.8, p = 0.005), while there was no impact of EGFR status on the TTD of patients who developed BM later. Conclusions. Except for a non-significant increase of frequency of BM at diagnosis in EGFR positive patients, EGFR status had no influence upon the cumulative incidence of BM. EGFR positive patients had a longer time to CNS progression. While EGFR positive patients with BM at diagnosis had a longer survival, EGFR status had no influence on TTD in patients who developed BM later during the course of disease.

Abstract: Leta 2019 so bila objavljena Priporočila za obravnavo bolnikov s pljučnim rakom, ki so v slovenski prostor vnesla prepotrebno poenotenje diagnostike in zdravljenja z namenom izboljšanja preživetja bolnikov s pljučnim rakom. Posodobitev Priporočil tri leta po izidu izvirnika prinaša največ novosti v poglavju o sistemskem zdravljenju bolnikov s pljučnim rakom. To kaže na izjemen napredek na področju razumevanja onkogeneze in biologije pljučnega raka ter s tem razvoja novih zdravil. Breme pljučnega raka ostaja veliko, saj je pljučni rak pri nas in v svetu še vedno najpogostejši vzrok smrti zaradi raka. Za vsako peto smrt zaradi raka je odgovoren pljučni rak. Skoraj tretjina bolnikov s pljučnim rakom ne prejme specifičnega onkološkega zdravljenja, bodisi zaradi slabega stanja zmogljivosti, spremljajočih bolezni ali obsega bolezni. Polovica bolnikov ima ob diagnozi razsejano bolezen, zaradi česar izboljšanje preživetja z malimi koraki sledi napredku v zdravljenju bolnikov s pljučnim rakom. Ti podatki nas opominjajo, da se bomo morali za velike premike v obravnavi bolnikov s pljučnim rakom lotiti drugačnih pristopov. Kot najbolj obetavno se ponuja zgodnje odkrivanje bolezni, ko so možnosti ozdravitve pljučnega raka najboljše. Zapisana Priporočila so usmeritev za obravnavo bolnikov s pljučnim rakom. Le s sodobnim multidisciplinarnim pristopom obravnave lahko bolniku ponudimo zdravljenje, ki mu omogoča najboljši izhod prognostično neugodne bolezni.

Zdravljenje bolnikov v zgodnjem stadiju bolezni : stereotaktično obsevanje
Karmen Stanič, 2023, published scientific conference contribution

Abstract: Stereotaktično obsevanje je natančno obsevanje, pri katerem je doza vsakega posameznega obsevanja in skupna doza zelo visoka, skupno število pa ne presega osem obsevanj. Doza in število frakcij sta odvisna od lege in velikosti tumorja. Na ta način obsevamo inoperabilne bolnike z zgodnjim pljučnim rakom ali tiste, ki operacijo odklonijo. SBRT tehnika omogoča le obsevanje tumorjev, ki so med obsevanjem vidni, ne obsevamo pa ultra-centralno ležečih tumorjev in tistih, ki vraščajo v mediastinalne strukture. V Sloveniji obsevamo s SBRT tehniko od leta 2016. Raziskave kažejo, da lokalne kontrole po 5 letih znašajo preko 90 %, celokupna preživetja pa so po petih letih nekoliko slabša kot za bolnike, ki so operabilni.

Oligometastatski rak
Ivica Ratoša, Karmen Stanič, Tanja Ovčariček, Ajra Šečerov Ermenc, Janka Čarman, Blaž Grošelj, Staša Jelerčič, Peter Korošec, Manja Šešek, Marko Kokalj, Gaber Plavc, Miha Oražem, Helena Barbara Zobec Logar, 2022, review article

Abstract: Oligometastatska bolezen (OMB) predstavlja vmesno stanje med lokalno napredovalo boleznijo in obsežnejšo metastatsko boleznijo. Zaenkrat ne poznamo specifičnih biomarkerjev, ki bi nam pomagali opredeliti bolnike z majhnim bremenom bolezni, zato diagnoza OMB temelji na slikovni diagnostiki. V zadnjih letih narašča zanimanje za optimizacijo zdravljenja OMB predvsem zaradi obetavnih rezultatov dodatka lokalnega k obstoječemu sistemskemu zdravljenju. S takšnim načinom zdravljenja se je prvič pokazala možnost doseganja dolgotrajnih zazdravitev ali redko celo ozdravitev teh bolnikov. Razlikovanje posameznih vrst OMB in njihovo enotno poimenovanje je pomembno zlasti v kliničnih raziskavah, saj nam omogoča medsebojno primerjavo rezultatov različnih raziskav.
