(1) Background: Inflammatory breast cancers (IBC) are characterized by a poor prognosis. This retrospective study aims to describe the clinical outcomes of non-metastatic IBC patients treated with a multidisciplinary approach with neo-adjuvant chemotherapy, surgery, and radiotherapy. (2) Methods: This single-center retrospective study included all women patients diagnosed with non-metastatic IBC between January 2010 and January 2018 at the Institut Curie (Paris, France) and treated with neoadjuvant chemotherapy, surgery, and radiotherapy. Overall survival (OS), disease-free survival (DFS), and locoregional free survival (LRRFS) were calculated from the time of diagnosis. Prognostic factors for patient survival were analyzed based on univariate and multivariate regressions. (3) Results: We identified 113 patients with a median age of 51 years. 79.7% had node-positive tumors; triple-negative breast cancers (TNBC) represented 34.6% of the cases. A large majority of patients (91.2%) received adjuvant post-mastectomy while ten patients (8.8%) received preoperative radiotherapy. Non-pathological complete response (non-pCR) was observed in 67.3% of patients. Radiotherapy delivered a median dose of 50 Gy to the breast or the chest wall in 25 fractions. With a median follow-up of 54 months, 5-year OS, DFS and LRRFS were 78% (CI: 70.1–86.8%), 68.1% (59.6–77.7%), and 85.2% (78.4–92.7%), respectively. In multivariate analysis, non-pCR was an adverse prognosis factor for OS, DFS, and LRRFS; pre-operative radiotherapy was an adverse prognosis factor for OS and DFS. Radiation-related adverse events were limited to acute skin toxicity (22% of Grade 2 and 2% of grade 3 dermatitis); no late radiation-induced toxicity was reported. (4) Conclusions: High locoregional control could be achieved with multidisciplinary management of non-metastatic IBC, suggesting the anti-tumor efficacy of radiotherapy in this rare but pejorative clinicopathological presentation. While comparing favorably with historical cohorts, OS and DFS could be potentially improved in the future with the use of new systemic treatments, such as PARP-inhibitors or immunotherapy.

Close Relationship

Triple negative breast cancer (TNBC) is a heterogeneous disease representing about 15% of all breast cancers. TNBC are usually high-grade histological tumors, and are generally more aggressive and difficult to treat due to the lack of targeted therapies available, and chemotherapy remains the standard treatment. There is a close relationship between pathological complete response after chemotherapy treatment and higher rates of disease-free survival and overall survival. In this review of systemic treatment in early triple negative breast cancer, our purpose is to analyze and compare different therapies, as well as to highlight the novelties of treatment in this breast cancer subtype.

Abstract Background There is no consensus yet for the best treatment regimen in patients with recurrent rectal cancer (RRC). This study aims to evaluate toxicity and oncological outcomes after re-irradiation in patients with RRC in our center. Clinical (cCR) and pathological complete response (pCR) rates and radicality were also studied. Methods Between January 2010 and December 2018, 61 locally advanced RRC patients were treated and analyzed retrospectively. Patients received radiotherapy at a dose of 30.0–30.6 Gy (reCRT) or 50.0–50.4 Gy chemoradiotherapy (CRT) in cases of no prior irradiation because of low-risk primary rectal cancer. In both groups, patients received capecitabine concomitantly. Results In total, 60 patients received the prescribed neoadjuvant (chemo)radiotherapy followed by surgery, 35 patients (58.3%) in the reRCT group and 25 patients (41.7%) in the long-course CRT group. There were no significant differences in overall survival (p = 0.82), disease-free survival (p = 0.63), and local recurrence-free survival (p = 0.17) between the groups. Patients in the long-course CRT group reported more skin toxicity after radiotherapy (p = 0.040). No differences were observed in late toxicity. In the long-course CRT group, a significantly higher cCR rate was observed (p = 0.029); however, there was no difference in the pCR rate (p = 0.66). Conclusions The treatment of RRC patients with re-irradiation is comparable to treatment with long-course CRT regarding toxicity and oncological outcomes. In the reCRT group, less cCR was observed, although there was no difference in pCR. The findings in this study suggest that it is safe and feasible to re-irradiate RRC patients.

Abstract   In recent years, immune checkpoint inhibitors (ICIs) have shown promising results in the treatment of ESCC. More than 20 phase II clinical trials have been launched to explore combinations of ICIs in the neoadjuvant setting for ESCC. Based on our phase II clinical trial, a two-arm phase III trial was launched in our Hospital. Methods A two-arm phase III trial was launched in April 2020 in our Hospital. Patient recruitment will be completed within 18 months. The primary endpoint is event-free survival (EFS). The secondary endpoints include pathologic complete response (pCR), disease-free survival (DFS) rate, overall response rate (ORR), R0 resection rate, major pathologic response (MPR), adverse events (AEs), complication rate and quality of life (QOL). A biobank of pretreatment, resected tumor tissue and paired blood samples will be built for translational research in the future. Results Until Dec. 2021, one hundred and twenty ESCC patients recruited in the trial. The trial is ongoing. Conclusion This RCT directly compares NAC with neoadjuvant toripalimab plus chemotherapy in terms of EFS for locally advanced ESCC. The results may usher in a new era of resectable ESCC treatment.

Abstract Background The purpose of this phase II study was to evaluate the feasibility of hypofractionated radiotherapy (HFRT) with a dose of 36.5 Gy in 10 fractions in postmastectomy patients. Methods From March 2014 to December 2015, 85 patients with locally advanced breast cancer were eligible to participate in this study with a schedule of 36.5 Gy in 10 fractions. Intensity-modulated radiation therapy (IMRT) was delivered to the chest wall with or without the supraclavicular region. The primary endpoint was radiation-related toxicities. The secondary endpoints were locoregional failure-free survival (LRFFS), disease-free survival (DFS) and overall survival (OS). And the outcomes were compared with our retrospective study of 72 patients with 42.5 Gy in 16 fractions. Results The median follow-up was 69.0 (range 66.5-71.5) months in the 36.5 Gy group and 93.0 (range 91.9-94.1) months in the 42.5 Gy group, respectively. Radiation-related toxicities were mainly grade 1, although a few patients had grade 2 plexopathy (1.2%) and acute skin toxicity (1.2%) in the 36.5 Gy group, and grade 2 acute skin toxicity (5.6%) and lymphedema (4.2%) in the 42.5 Gy group. There were no significant differences between the groups in acute and late toxicities. For all the patients, the 5-year LRFFS, DFS and OS were 97.7 and 100.0%, 93.1 and 90.3%, 98.8 and 97.2%, respectively, without significant differences between the groups. Conclusion Postmastectomy HFRT with a schedule of 36.5 Gy in 10 fractions was feasible, with mild toxicities and excellent 5-year clinical outcome.

<b><i>Objective:</i></b> The aim of this study was to evaluate the long-term outcomes and the factors related to patient prognosis. <b><i>Materials and Methods:</i></b> We retrospectively analyzed patients treated at the Department of Gynecology, Sun Yat-sen University Cancer Center, between January 1, 1968, and December 12, 2018. <b><i>Results:</i></b> A total of 107 patients were identified. Of all patients, 79 (73.8%) presented with stage I disease, 14 (13.1%) stage II, 13 (12.2%) stage III, and 1 (0.9%) stage IV. All patients received surgery, with 70 (65.4%) undergoing fertility-sparing surgery (FS) and 37 (34.6%) nonfertility-sparing surgery (NFS). Ninety patients received postoperative chemotherapy. Nine of the 43 cases with a lymphadenectomy had metastasis (20.9%). The median follow-up time was 132 months (range, 1–536 months). The overall 5-year and 10-year survival was 95.1% and 91.7%, respectively. The 10-year survival rate for stage I and II–IV patients was 96.1% and 79.1%, respectively (<i>p</i> = 0.008). For the patients undergoing FS and NFS, the 10-year disease-free survival rate was 82.3% and 88.0%, respectively (<i>p</i> = 0.403). The 10-year disease-free survival rate for patients with or without lymphadenectomy was 95.1% and 78.4%, respectively (<i>p</i> = 0.040), and it was 92.5% and 76.0%, respectively (<i>p</i> = 0.041), for those with or without omentectomy. Fifteen patients relapsed, and 4 of them (26.7%) had recurrence in the lymph nodes. Eleven of the 15 relapsed patients (73.3%) had been successfully salvaged. <b><i>Limitations:</i></b> As a study of a rare disease, our analysis was limited by its small sample size and the deemed disadvantage of a retrospective study. <b><i>Conclusion:</i></b> Excellent treatment results can be achieved in dysgerminoma patients who received proper treatment. Lymphadenectomy may improve patient survival. Relapsed patients can also be successfully salvaged.

The aim of the study: to increase the frequency of achieving pathologic complete response and increase disease-free survival in the investigational group of patients with locally advanced rectal cancer T3(MRF+)–4N0–2M0 by developing a new strategy for neoadjuvant therapy.Materials and methods. In total, 414 patients were assigned to treatment. Control group I included 89 patients who underwent radiotherapy (RT) 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week. Control group II included 160 patients who underwent RT 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week and oxaliplatin once a week, during the course of RT. Study group III consisted of 165 patients. This group combined RT 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week and additional consecutive CapOx cycles. This group was divided into 2 subgroups: subgroup IIIa included 106 patients with consolidating chemotherapy (after CRT); subgroup IIIb included 59 patients who underwent “sandwich” treatment. Therapy consisted of conducting from 1 to 2 cycles of induction CapOx (up to CRT) and from 1 to 2 cycles of consolidating CapOx with an interval of 7 days. In the interval between the courses of drug therapy, RT 52–56 Gy/26–28 fractions was performed. According to the results of the control examination, further treatment tactics were determined. The primary end points were 5-year disease-free survival and the achievement of a pathologic complete response.Results. Pathologic complete response was significantly more often recorded in patients in the investigational group III (17.48 %; p = 0.021) compared with control groups (7.95 % in the I group and 8.28 % in the II group). 5-year disease-free survival in patients in the study groups was: 71.5 % in the III group, 65.6 % in the II group and 56.9 % in the I group.Conclusion. The shift in emphasis on strengthening the neoadjuvant effect on the tumor and improving approaches to drug therapy regimens have significantly improved disease-free survival of patients with locally advanced rectal cancer.

Abstract Fifty-two patients with stage III or IV nodular mixed lymphocytic- histiocytic lymphoma (NM) were entered on a prospective randomized trial comparing cyclophosphamide-prednisone (CP) to either COPP (cyclophosphamide, vincristine, procarbazine, prednisone) or BCVP (BCNU, cyclophosphamide, vincristine, prednisone). The COPP regimen utilized in this Eastern Cooperative Oncology Group (ECOG) trial was similar to the four-drug regimen C-MOPP reported by the National Cancer Institute to achieve prolonged relapse-free survival in this histology. No significant differences in complete response rates, response duration, or overall survival were noted among the three regimens. A pattern of continuous late relapse was observed for all three chemotherapy programs. Although 11 of the 18 (61%) COPP patients achieved a complete response, only 3/11 (27%) remain disease-free with a median follow-up of over 3 yr. However, two of these three long-term complete responders have died with no clinical evidence of recurrent disease. The COPP patients received 84% of the calculated ideal doses of cyclophosphamide and 78% of the ideal dosage of procarbazine. Grade 3–4 hematologic toxicity was noted in 22% of the COPP group, 36% with BCVP, and 0% for the CP patients. We were unable to confirm the ability of COPP to achieve durable complete remissions in NM lymphoma. The cyclophosphamide-prednisone combination was equally effective when compared with COPP and BCVP, but produced minimal toxicity.

Preclinical works have suggested cytotoxic chemotherapies may increase the number of cancer stem cells (CSC) whereas angiogenesis inhibition may decrease CSC proliferation. We developed a proof of concept clinical trial to explore bevacizumab activity on breast CSC. Breast cancer patients requiring preoperative chemotherapy were included in this open-label, randomized, prospective, multicenter phase II trial. All received FEC-docetaxel combination, and patients randomized in the experimental arm received concomitant bevacizumab. The primary endpoint was to describe ALDH1 (Aldehyde dehydrogenase 1) positive tumor cells rate before treatment and after the fourth cycle. Secondary objectives included safety, pathological complete response (pCR) rate, disease-free survival (DFS), relapse-free survival (RFS), and overall survival (OS). Seventy-five patients were included. ALDH1+ cells rate increase was below the predefined 5% threshold in both arms for the 32 patients with two time points available. Grade 3 or 4 adverse events rates were similar in both arms. A non-significant increase in pCR was observed in the bevacizumab arm (42.6% vs. 18.2%, p = 0.06), but survival was not improved (OS: p = 0.89; DFS: p = 0.45; and RFS: p = 0.68). The increase of ALDH1+ tumor cells rate after bevacizumab-based chemotherapy was less than 5%. However, as similar results were observed with chemotherapy alone, bevacizumab impact on breast CSC cells cannot be confirmed.

A randomized clinical trial of combination chemotherapy for patients who relapsed following primary radiation therapy for Hodgkin's disease was conducted from 1975 to 1981 by the Cancer and Leukemia Group B (CALGB). One hundred thirteen patients were prospectively randomized to receive 12 cycles of either CVPP (CCNU, vinblastine, procarbazine, and prednisone), ABOS (bleomycin, vincristine [Oncovin; Lilly, Indianapolis], doxorubicin [Adriamycin, Adria Laboratories, Columbus, Ohio], and streptozotocin), or alternating cycles of CVPP and ABOS. The median length of observation for patients in this report is 4 years. Toxicities of the three treatment programs were primarily hematologic. Frequencies of complete response were 72% for CVPP, 70% for ABOS, and 82% for CVPP/ABOS (P = .37). Females and patients who had nodular sclerosing disease at initial diagnosis had significantly higher complete response rates. The 5-year disease-free survival for the complete responders was 55%; the 5-year overall survival was 60%. There were no significant differences among the treatments on disease-free survival (P = .78) or overall survival (P = .18). Age under 40 years was the only significant positive prognostic factor for disease-free survival (P = .095) and overall survival (P = .003). This study demonstrates no statistically significant advantage for alternating cycles of combination chemotherapy in affecting complete response frequency, disease-free survival, or overall survival as compared with therapy with CVPP or ABOS alone. However, the power to detect differences in these outcome parameters is somewhat limited by the sample sizes.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract Background The aim of this study is to compare the outcome of patients with adenocarcinoma of the distal oesophagus (AEG Type I) treated with perioperative chemotherapy or neoadjuvant chemoradiation. Methods A retrospective analysis of eligible patients from four Austrian centers was conducted. All patients with AEG type I treated between January 2007 and October 2017 with chemotherapy (EOX-protocol) or chemoradiation (CROSS-protocol, or 5-FU/Cisplatin), followed by oesophagectomy were included in the study. Primary outcomes overall survival, and disease free survival as well as secondary outcomes, achievement of pathological complete response pCR (ypT0N0M0) or downstaging of T- or N-stage were analyzed. Primary outcomes were calculated by the Kaplan-Meier-method. Results Data of 117 patients were analyzed, 59 received chemoradiation (50/59 CROSS and 9/59 5-FU/Cisplatin) and 58 patients received perioperative chemotherapy (EOX). Complete data at time of submission were available in 40 patients in the chemoradiation group and in 37 patients in the chemotherapy group. The median follow-up time in the chemoradiation group was 13,0 months (CI 95%: 11,0–15,0) and in the chemotherapy group 45,0 months (CI 95%: 28,8–61,3). Overall survival rate in the EOX group after ½, 1, 3 and 5 years was 92%, 83%, 63% and 34%. So far long term data are not available after chemoradiation, after ½ year overall survival was 84% and after one year 60%. Disease free survival rate in the EOX group after ½, 1, 3 and 5 years was 91%, 81%, 54% and 32%, in the chemoradiation group after ½ and one year 80% and 50%. A significant difference was found in the pathological complete response (pCR) rate, it was achieved in 19% of patients after chemoradiation and in 3% after chemotherapy (P = 0000). Conclusion Concerning major response of the primary tumor there are clear advantages for chemoradiation. In regards to systemic tumor control there seems a tendency in favor for chemotherapy.
