1.

Patient registries represent a tool to assess and follow treatment outcomes in this patient population. The aim of the study was with the help of the patients% register to determine the safety and efficacy of bevacizumab plus chemotherapy in elderly patients who had previously untreated metastatic colorectal cancer. Patients and methods. The registry of patients with mCRC was designed to prospectively evaluate the safety and efficacy of bevacizumab-containing chemotherapy as well as selection of patients in routine clinical practice. Patient baseline clinical characteristics, pre-specified bevacizumab-related adverse events, and efficacy data were collected, evaluated and compared according to the age categories. Results. Between January 2008 and December 2010, 210 patients with mCRC (median age 63, male 61.4%) started bevacizumab-containing therapy in the 1st line setting. Majority of the 210 patients received irinotecan-based chemotherapy (68%) as 1st line treatment and 105 patients (50%) received bevacizumab maintenance therapy. Elderly (% 70 years) patients presented 22.9% of all patients and they had worse performance status (PS 1/2, 62.4%) than patients in < 70 years group (PS 1/2, 35.8%). Difference in disease control rate was mainly due to inability to assess response in elderly group (64.6% in elderly and 77.8% in < 70 years group, p = 0.066). The median progression free survival was 10.2 (95% CI, 6.7%16.2) and 11.3 (95% CI, 10.2%12.6) months in elderly and < 70 years group, respectively (p = 0.58). The median overall survival was 18.5 (95% CI, 12.4%28.9) and 27.4 (95% CI, 22.7%31.9) months for elderly and < 70 years group, respectively (p = 0.03). Three-year survival rate was 26% and 37.6% in elderly vs. < 70 years group (p = 0.03). Overall rates of bevacizumab-related adverse events were similar in both groups: proteinuria 21/22 %, hypertension 25/19 %, haemorrhage 2/4 % and thromboembolic events 10/6 %, for elderly and < 70 years group, respectively. Conclusions. In routine clinical practice, the combination of bevacizumab and chemotherapy is effective and welltolerated regimen in elderly patients with metastatic colorectal cancer.

2. Bevacizumab and irinotecan in recurrent malignant glioma, a single institution experienceTanja Mesti, Maja Ebert Moltara, Marko Boc, Martina Reberšek, Janja Ocvirk, 2015, izvirni znanstveni članek Povzetek: Treatment options of recurrent malignant gliomas are very limited and with a poor survival benefit. The results from phase II trials suggest that the combination of bevacizumab and irinotecan is beneficial. Patients and methods. The medical documentation of 19 adult patients with recurrent malignant gliomas was retrospectively reviewed. All patients received bevacizumab (10 mg/kg) and irinotecan (340 mg/m2 or 125 mg/m2) every two weeks. Patient clinical characteristics, drug toxicities, response rate, progression free survival (PFS) and overall survival (OS) were evaluated. Results. Between August 2008 and November 2011, 19 patients with recurrent malignant gliomas (median age 44.7, male 73.7%, WHO performance status 0%2) were treated with bevacizumab/irinotecan regimen. Thirteen patients had glioblastoma, 5 anaplastic astrocytoma and 1 anaplastic oligoastrocytoma. With exception of one patient, all patients had initially a standard therapy with primary resection followed by postoperative chemoradiotherapy. Radiological response was confirmed after 3 months in 9 patients (1 complete response, 8 partial responses), seven patients had stable disease and three patients have progressed. The median PFS was 6.8 months (95% confidence interval [CI]: 5.3-8.3) with six-month PFS rate 52.6%. The median OS was 7.7 months (95% CI: 6.6-8.7), while six-month and twelve-month survival rates were 68.4% and 31.6%, respectively. There were 16 cases of hematopoietic toxicity grade (G) 1-2. Non-hematopoietic toxicity was present in 14 cases, all G1-2, except for one patient with proteinuria G3. No grade 4 toxicities, no thromboembolic event and no intracranial hemorrhage were observed. Conclusions. In recurrent malignant gliomas combination of bevacizumab and irinotecan might be an active regimen with acceptable toxicity.

3. Rak jajčnikov : česa še ne vemo? : ginekološki simpozij : Ljubljana, 2. 12. 2021 : zbornik znanstvenih prispevkov2021, zbornik strokovnih ali nerecenziranih znanstvenih prispevkov na konferenci Povzetek: Ginekološki simpozij Rak Jajčnika: Česa še ne vemo? zajema sklop predavanj, kjer so predstavljeni začetna obravnava žensk s tumorji v področju jajčnikov, nadaljnja predoperativna priprava, najradikalnejši kirurški posegi in zadnje smernice na področju sistemske terapije. Prav tako pozornost namenjamo tudi stereotaktičnemu obsevanju in imunoterapiji, ki na področju ginekoloških rakov počasi dobiva svojo veljavo in mesto.

4. Naše izkušnje z zdravilom bevacizumab v primarnem zdravljenju epitelijskega raka jajčnikovErik Škof, Dushan Mangaroski, 2020, izvirni znanstveni članek Povzetek: Izhodišče: Zdravilo bevacizumab uporabljamo v sklopu primarnega sistemskega zdravljenja napredovalega epitelijskega raka jajčnikov v kombinaciji s paklitakselom in karboplatinom od leta 2013.
Namen: Prikazati učinkovitost in varnost zdravljenja z bevacizumabom v redni klinični praksi v sklopu primarnega zdravljenja raka jajčnikov.
Metode: V retrospektivno analizo smo vključili bolnice z epitelijskim rakom jajčnikov, ki so se zdravile z bevacizumabom na Onkološkem inštitutu Ljubljana v obdobju od 1. 1. 2013 do 31. 12. 2016. Cilja raziskave sta bila varnost in učinkovitost (preživetje brez ponovitve bolezni, celokupno preživetje) zdravljenja z bevacizumabom. Raziskavo je odobrila etična komisija na Onkološkem inštitutu Ljubljana.
Rezultati: V opazovanem obdobju je bilo z bevacizumabom zdravljenih 111 bolnic z napredovalim epitelijskim rakom jajčnikov. Najpogostejši neželeni učinki so bili: bolečine (52 %), krvavitev (45 %), arterijska hipertenzija (44 %). Resne neželene učinke (stopnja 3/4) je imelo 12 % bolnic: venska tromboza/ embolija (3 %), proteinurija (3 %), arterijska hipertenzija (2 %), krvavitev (2 %), bolečine (1 %), fistula (1 %). Mediani čas sledenja je bil 59 mesecev. Mediano preživetje brez ponovitve bolezni je bilo 18 mesecev, mediano celokupno preživetje pa 41 mesecev.
Zaključki: Zdravljenje z bevacizumabom v redni klinični praksi je varno in učinkovito ‒ v skladu z do zdaj znanimi rezultati prospektivnih raziskav GOG 218 in ICON 7.
