Strategies to improve long-term outcome in stage IIIB inflammatory breast cancer: multimodality treatment including dose-intensive induction and high-dose chemotherapy.

ABSTRACT: Inflammatory breast cancer (IBC) is a rare clinicopathologic entity with a poor prognosis, lagging far behind any other form of nonmetastatic breast cancer. Since the advent of systemic chemotherapy over 35 years ago, only minimal progress has been made in long-term outcome. Although multiple randomized trials of high-dose chemotherapy and autologous progenitor cell transplantation (ASCT) for the treatment of breast cancer have yielded disappointing results, these data are not necessarily relevant to IBC, a distinct clinical and pathologic entity. Therefore, the optimal multimodality therapy for IBC is not well established, and remains unsatisfactory. We treated 21 women with nonmetastatic IBC with a multimodality strategy including high-dose melphalan (Mel)/etoposide and ASCT. The treatment was overall tolerated with acceptable morbidity, and no post-ASCT 100-day mortality. With a median potential follow-up of approximately 8 years, the estimated progression-free survival (PFS), event-free survival (EFS), and overall survival (OS) at 6 years from on-study date are: 67%, 55%, and 69%, respectively. These results from a small phase II study are among the most promising of mature outcome data for IBC. They strongly suggest, along with results of several already published phase II trials, that ASCT could play a significant role in the first line treatment of IBC.

Project description:BackgroundResearches on programmed cell death (PD-1) as neoadjuvant immunotherapy for resectable non-small cell lung cancer is underway, which brings hope for individuals with the disease. However, a study dedicated to lung squamous cell carcinoma (LUSC) specifically has yet to be conducted. Now, data from our pilot prospective research neoadjuvant study provide new insights in the field of neoadjuvant regimen for LUSC.MethodsBetween June 2019 and July 2020, 37 adults with untreated, surgically resectable stage IIB-IIIB LUSC were enrolled into this prospective study. Patients received 2 cycles of pembrolizumab (2 mg/kg) with chemotherapy (albumin-bound paclitaxel 100 mg/m2 on days 1 and 8 + carboplatin AUC 5) via intravenous administration every 3 weeks, and underwent surgical treatment 3-4 weeks after the second cycle. The primary endpoint of the study was the tumor pathologic complete response (pCR) rate. The toxicity profile, tumor major pathological remission, complete resection rate, response rate, and operative and postoperative complications were also evaluated.ResultsThe postoperative pathological specimens of 17 (45.9%) patients suggested pCR. Neoadjuvant pembrolizumab with chemotherapy had an acceptable side-effect profile, and no patients withdrew from the study preoperatively due to disease progression or toxicity. A major pathological response occurred in 24 (64.9%) resected tumors. All tumors were completely resected (R0, 100%). According to the Response Evaluation Criteria in Solid Tumors (RESIST), a response was evaluated before surgery in 32 (86.5%) patients by computed tomography. Twenty-five (67.6%) patients underwent thoracoscopic surgery. No deaths or postoperative major complications requiring reoperation occurred. Recurrence or metastasis was found in 2 patients during follow-up of 2-14 months.ConclusionsThe early outcomes of pembrolizumab with chemotherapy in the neoadjuvant setting as a novel treatment for resectable stage IIB-IIIB LUSC showed a high pCR rate that has not been seen previously, as well as a high R0 resection rate and a low toxicity profile. The long-term efficacy of this novel treatment and the validity of the present findings should be confirmed with longer follow-up and prospective comparative trials.

Project description:BackgroundPreviously, stage-IIIB non-small cell lung cancer (NSCLC) has been considered inoperable. In recent years, neoadjuvant immunotherapy has shown encouraging efficacy in the treatment of advanced stage NSCLC in several trials. However, the effectiveness and safety of neoadjuvant immunotherapy in treating stage-IIIB NSCLC are still unknown. Therefore, we conducted this retrospective study to examine the outcomes of surgery after neoadjuvant immunotherapy combined with chemotherapy for stage-IIIB NSCLC.MethodsThirty patients with stage-IIIB NSCLC who were treated at the Department of Thoracic Surgery of Renji Hospital from January 2019 to September 2021 were analyzed retrospectively. Neoadjuvant immunotherapy combined with chemotherapy was administered prior to surgery. The curative effect was evaluated by imaging and pathological examinations.ResultsThe objective response rate (ORR) and disease control rate (DCR) of the patients after neoadjuvant therapy evaluated by imaging studies were 70% and 86.7%, respectively. Of the 30 patients, 19 (63%) underwent surgical resection, in which all achieved a complete R0 resection. The median operative time was 168 minutes (range, 75-295 minutes), and the average intraoperative blood loss was 215.3±258.4 mL. The median postoperative hospital stay was 8 days (range, 4-59 days). The major pathological response (MPR) rate was 73.7% (14/19), and the pathological complete response rate was 47.4% (9/19); 2/30 patients (6.7%) had postoperative complications, including two who developed bronchopleural fistulas and one mortality, from a postoperative pulmonary infection. The treatment-related adverse reactions were mainly grades 1-2. Only two patients had grade 3 anemia, and no grade 4 adverse reactions were observed.ConclusionsNeoadjuvant immunotherapy and chemotherapy combined with surgery in patients with stage-IIIB NSCLC is safe and feasible. The patient outcomes and optimal number of neoadjuvant treatment cycles need to be explored and studied further.
