Background. The MF07-01 trial is a multicenter randomized study comparing locoregional treatment (LRT) followed by systemic therapy (ST) with ST alone in de novo Stage IV breast cancer (BC) patients. Aim: To evaluate and finalize the survival data of LRT in patients with the diagnosis of de novo Stage IV BC. Methods. At initial diagnosis, patients were randomized 1:1 to either the LRT or ST group. All the patients were given ST either immediately after randomization or after surgical resection of the intact primary tumor. Continuous and categorical variable differences between LRT and ST groups were analyzed using t-test and Chi-square test, respectively. Overall survival (OS) and 5-year survival rates were compared using Kaplan-Meier log-rank tests. Univariate and multivariate Cox models were used to estimate hazard ratios, and logistic regession model used to estimate odds ratio. Results. During more than 10 years follow-up, 23% of patients in LRT group and 8% of patients in ST group were alive. Median survival was 46 months for LRT (n=134) and 35 months for ST (n=131) [HR:0.71, 95%CI;0.59-0.86, p=0.0004]. Solitary bone metastasis patients’ median survival was 14 months longer in LRT group comparing ST group [HR:0.55, 95%CI; 0.35-0.86, p=0.008]; 16% of solitary bone metastasis patients in the LRT group were alive, but all patients died in the ST group. Patients younger than 55 lived longer compared the patients older than 55 [HR:0.67, 95%CI; 0.52-0.87, p=0.002], and 26% of hormone receptor positive patients were still alive in the LRT group comparing 10% in the ST group [HR:0.71, 95%CI; 0.58-0.88, p=0.002]. Regarding the patients who lived at least 5 years since randomization, LRT (p=0.003), hormone receptor positivity (p=0.004), Triple negative status (p=0.02), hormonotherapy (p=0.0001), bisphosphonates usage (p=0.03), and 2 or more organ metastases (p=0.004) were associated with OS in univariant analyses. However, in the multivariate model with significant baseline and clinical characteristics only LRT [OR= 1.58, p=0.03] was found to be significantly related with over 5 years of survival. Conclusion. In the current analysis, patients at the diagnosis of de novo stage IV BC who underwent LRT followed by ST had a 58% higher chance to live at least 5 years compared to the patients who received only ST. Longer follow-up of the study discloses that LRT should be presented to patients when discussing treatment options.
The role of loco-regional treatment in long-term quality of life in de novo stage IV breast cancer patients: Protocol MF07-01Q
(Springer, 2021-07) Soran, Atilla; Soyder, Aykut; Özbaş, Serdar; Özmen, Vahit; Karanlık, Hasan; İğci, Abdullah; Müslümanoğlu, Mahmut; Cantürk, Zafer; Utkan, Zafer; Özaslan, Cihangir; Uras, Cihan; Uğurlu, Ümit; Col, Cavit; Cabioğlu, Neslihan; Uzunköy, Ali; Güllüoğlu, Bahadır M.; Erdem, Ergün; Konca, Can; Sezgin, Efe; Evrensel, Türkkan; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Onkoloji Anabilim Dalı.; 0000-0002-9732-5340; AAJ-1027-2021; 6603942124
Background/objective Since more solid evidence has emerged supporting the effectiveness of loco-regional treatment (LRT), clinicians consider LRT a treatment option for selected de novo stage IV breast cancer (BC) patients. This is the first report on long-term quality of life (QoL) in a cohort of patients who were randomized to receive either LRT and then systemic treatment (ST) or ST alone in the protocol MF07-01. We aimed to evaluate QoL in patients living at least 3 years since randomization using scores from the SF-12 health survey. Methods SF-12 (V2) forms were completed during visits of patients who were living 36 months after the randomization. We first calculated PCS-12 (Physical Health Composite Scale) and MCS-12 (Mental Health Composite Scale) scores from de novo stage IV BC patients and compared them with the scores of patients diagnosed with stage I-III BC who lived more than 3 years. Further, PCS-12 and MCS-12 scores were compared between the LRT and ST groups with de novo stage IV BC. Additionally, general health, physical functioning, role functioning, bodily pain, vitality, mental health, and social functioning were evaluated and compared between the groups. Considering age-related changes in QoL, we also compared PCS-12 and MCS-12 scores of patients below or above 55 and 65 years of age. Responses to four additional questions (compare your physical health, mental health, daily activities, and energy currently vs. at diagnosis of BC) were recorded, considering cultural differences. Results There were 81 patients in this analysis; 68% of patients (n = 55) had LRT, and 32% (n = 26) received ST. General health was good or very good in 62% (n = 34) in the LRT group and 66% (n = 17) in the ST-only group (p = 0.63). Mean PCS-12 score was 40.8 + 1.6, and mean MCS-12 score was 43.4 + 2.0 (p = 0.34 and p = 0.54, respectively). PCS-12 and MCS-12 score difference was lower than that of the general Turkish population (PCS-12 = 49.3 + 12.8 and MCS-12 = 46.8 + 13.0) and stage I-III BC patients (PCS-12 = 51.1 +/- 0.5, MCS-12 = 45.7 +/- 0.6). PCS-12 and MCS-12 scores were similar between the LRT and ST-only groups in patients younger and older than 55 and 65, but QoL scores were much better in stage I-III BC patients younger than 65 when compared to the scores of those with de novo stage IV BC. Although treatment with or without LRT did not affect physical health, mental health, daily activities, and energy at 3 years vs. at diagnosis of BC in de novo stage IV BC patients (p > 0.05), these variables were significantly better in stage I-III BC patients (p < 0.001). Conclusion The current MF07-01Q study demonstrates that patient who had LRT has similar physical and mental health outcomes compared to ST only in a cohort of patients who lived longer than 3 years. Trial registration This study is registered on clinicaltrials.gov with identifier number NCT00557986.
