Low-dose cisplatin administration through the superficial temporal artery combined with definitive radiotherapy for maxillary sinus squamous cell carcinoma.

e18562 Background: Although patients with locoregional advanced maxillary sinus squamous cell carcinoma (MSSCC) are often treated with surgery followed by postoperative radiotherapy (RT), the cosmetic and functional outcomes are unsatisfactory. Moreover, the efficacy and safety of intra-arterial chemoradiotherapy are controversial. Methods: In this study, we investigated the efficacy and safety of low-dose cisplatin administration through the superficial temporal artery (STA) combined with definitive RT in patients with MSSCC. Between January 2009 and December 2018, 57 patients were administered weekly intra-arterial infusions of cisplatin (30–50 mg/m2/5h) through the STA with simultaneous intravenous infusions of sodium thiosulfate. Overall response rate (ORR), local progression-free survival (LFS), maxillectomy-free survival (MFS), progression-free survival (PFS), overall survival (OS), and safety were evaluated retrospectively. The impact of clinical factors on survival was investigated using the Cox proportional hazard models. Results: The median follow-up time was 44 months (range, 10–80 months). There were 4, 26, 23, and 4 patients with cT2, cT3, cT4a, and cT4b, respectively. All patients completed the planned treatment except for one patient who discontinued owing to facial palsy. The ORR was 98% with 51 and 5 patients having complete and partial responses, respectively. The 3-year LFS, PFS, and OS were 74%, 63%, and 81%, respectively for all patients and 100%, 81%, and 94%, respectively for 22 patients received 70 Gy irradiation. Notably, the 3-year MFS was 95% for all patients and 100% in patients received 70 Gy RT. The most common grade 3 or more toxic event was oral mucositis (22.8%). Additionally, 4 (7.0%) patients had catheter-related infections. Late grade 3 or more adverse events included optic nerve disorder (8.8%), osteonecrosis (7.0%), encephalopathy (1.8%), and increased creatinine levels (1.8%). Salvage surgery including hard palate resection and orbital exenteration were performed in 2 and 1 patients, respectively. No clinical factor was correlated with survival outcomes in our study cohort. Conclusions: Low-dose cisplatin through STA combined with RT, especially 70 Gy RT, was associated with promising tumor response, high organ preservation rate, and tolerable adverse events in MSSCC patients. Further prospective studies are warranted to compare these outcomes with primary surgery.

PURPOSE: To investigate whether the addition of cisplatin (CDDP) to hyperfractionation (Hfx) radiation therapy (RT) offers an advantage over the same Hfx RT given alone in locally advanced (stages III and IV) squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: One hundred thirty patients were randomized to receive either Hfx RT alone to a tumor dose of 77 Gy in 70 fractions in 35 treatment days over 7 weeks (group I, n = 65) or the same Hfx RT and concurrent low-dose (6 mg/m2) daily CDDP (group II, n = 65). RESULTS: Hfx RT/chemotherapy offered significantly higher survival rates than Hfx RT alone (68% v 49% at 2 years and 46% v 25% at 5 years; P = .0075). It also offered higher progression-free survival (46% v 25% at 5 years; P = .0068), higher locoregional progression-free survival (LRPFS) (50% v 36% at 5 years; P = .041), and higher distant metastasis-free survival (DMFS) (86% v 57% at 5 years; P = .0013). However, there was no difference between the two treatment groups in the incidence of either acute or late high-grade RT-induced toxicity. Hematologic high-grade toxicity was more frequent in group II patients. CONCLUSION: As compared with Hfx RT alone, Hfx RT and concurrent low-dose daily CDDP offered a survival advantage, as well as improved LRPFS and DMFS.

Objective. To investigate the efficacy and safety of the treatment of the newly diagnosed multiple myeloma (MM) patients with the therapy of subcutaneous (subQ) administration of bortezomib and dexamethasone plus thalidomide (VTD) regimen.Methods. A total of 60 newly diagnosed MM patients were analyzed. 30 patients received improved VTD regimen (improved VTD group) with the subQ injection of bortezomib and the other 30 patients received conventional VTD regimen (VTD group).The efficacy and safety of two groups were analyzed retrospectively.Results. The overall remission (OR) after eight cycles of treatment was 73.3% in the VTD group and 76.7% in the improved VTD group (P>0.05). No significant differences in time to 1-year estimate of overall survival (72% versus 75%,P=0.848) and progression-free survival (median 22 months versus 25 months;P=0.725) between two groups. The main toxicities related to therapy were leukopenia, neutropenia, thrombocytopenia, asthenia, fatigue, and renal and urinary disorders. Grade 3 and higher adverse events were significantly less common in the improved VTD group (50%) than VTD group (80%,P=0.015).Conclusions. The improved VTD regimen by changing bortezomib from intravenous administration to subcutaneous injection has noninferior efficacy to standard VTD regimen, with an improved safety profile and reduced adverse events.

Which regimen, among cisplatin (DDP) (TP), carboplatin (CBP) (TC) or 5-Fu (TF) in combination with PTX concurrent with radiotherapy, provides best prognosis with minimum adverse events (AEs) is still unknown. Methods: The study compared two pairs of regimens: TF vs. TP and TF vs. TC concurrent with radiotherapy. Patients with histologically confirmed ESCC (clinical stage II, III or IVa) were randomized into the three groups. Patients in TP group were treated with 2 cycles of CCR followed by 2 cycles of consolidation chemotherapy with TP (DDP 25 mg/m2/d, d1-3, PTX 175 mg/m2, d1, q28d). Patients in TF group were treated with 6 cycles of TF (5-Fu 300 mg/m2, civ 96h, PTX 50 mg/m2, d1, qw) in CCR followed by 2 cycles of TF (5-FU 1800 mg/m2, civ 72h, PTX 175 mg/m2, d1, q28d) in consolidation chemotherapy. Patients in TC group were treated with 6 cycles of TC (CBP AUC = 2, d1, PTX 50 mg/m2, d1, qw) in CCR followed by 2 cycles of TC (CBP AUC = 5, d1, PTX 175 mg/m2 d1, q28d) in consolidation chemotherapy. The radiotherapy dose in all groups was 61.2 Gy delivered in 34 fractions. The primary endpoint was overall survival and the secondary endpoints were progression-free survival and adverse events. Results: Between July 2015 and January 2018, 321 ESCC patients in 11 centers were enrolled. TP group had a significant higher incidence of acute grade 3/4 neutropenia (59.7% vs. 16.8%(TF) or 32.4%(TC)), thrombocytopenia (12.7% vs. 3.5%(TF) or 6.2%(TC)), anemia (6.4% vs. 4.4%(TF) or 4.4%(TC)), fatigue (10.0% vs. 0.9%(TF) or 0.9%(TC)) and vomiting (5.5% vs. 0%(TF) or 0.9%(TC)) than other two groups ( P < 0.05). TF group had a significant higher incidence of grade 3/4/5 esophagitis (13.1% vs. 1.8%(TP) or 5.3%(TC)) and pneumonitis (4.4% vs. 0%(TP) or 1.8%(TC)) than other two groups ( P < 0.05). One patient in TF group died of acute pneumonitis. One patient in TF group and one in TC group died of acute esophagitis. Conclusions: TP and TF regimen showed different severe AEs in CCR in ESCC patients and TC showed mild AEs. Clinical trial information: NCT02459457.

Results: Between July 2015 and January 2018, 321 ESCC patients in 11 centers were enrolled. Median follow-up of patients who survived was 36.3 months (IQR 27.9–45.2). The 3-yr OS was 58.2% in TF group and 59.5% in both TP and TC group. (TF vs. TP, HR 0.935, 95% CI 0.627-1.417; TF vs. TC, HR 0.881, 95% CI 0.578-1.342; P = 0.839). No significant differences were found in 3-yr PFS between TF, TP and TC groups [48.3% vs. 45.5%(TP) or 48.3% (TC). P = 0.820]. TP group had a significant higher incidence of acute Grade 3/4 neutropenia [60.7% vs. 16.8%(TF) or 32.7%(TC)], thrombocytopenia [13.1% vs. 2.8%(TF) or 4.7%(TC)], anemia [5.6% vs. 1.9%(TF) or 3.7% (TC)], fatigue [10.3% vs. 1.9%(TF) or 0.9%(TC)] and vomiting [5.6% vs. 0%(TF) or 0.9%(TC))]than other two groups ( P< 0.05). TF group had a significant higher incidence of Grade 3/4/5 esophagitis [11.2% vs. 0.9%(TP) or 4.7%(TC))]and pneumonitis [4.6% vs. 0%(TP) or 1.9% (TC)]than other two groups ( P< 0.05). Conclusions: No statistical differences were found in OS and PFS among TF, TP and TC groups. TC might be an option used in CCR in ESCC patients with mild of side effects compared with other two groups, although it did not significantly prolong OS. Clinical trial information: NCT02459457 .

Abstract Background This retrospective study was to assess and compare the toxicity and efficacy of concurrent chemoradiotherapy (CCRT) with S-1 or docetaxel and cisplatin in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Methods Patients with locally advanced ESCC who received CCRT with S-1 (70 mg/m2 twice daily on days 1–14, every 3 weeks for 2 cycles, S-1 group) or docetaxel (25 mg/m2) and cisplatin (25 mg/m2) on day 1 weekly (DP group) between 2014 and 2016 were retrospectively analyzed. Radiotherapy was delivered in 1.8–2.0 Gy per fraction to a total dose of 50–60 Gy. Treatment-related toxicities (Common Terminology Criteria for Adverse Events version 4.0), response rate, and survival outcomes were compared between groups. Results A total of 175 patients were included in this study (72 in the S-1 group and 103 in the DP group). Baseline characteristics were well balanced between the two groups. The incidence of grade 3–4 adverse events were significantly lower in the S-1 group than that of the DP group (22.2% vs. 45.6%, p = 0.002). In the DP group, elderly patients (> 60 years) had a significantly higher rate of grade 3–4 adverse events than younger patients (58.1% vs. 31.3%, p = 0.01). The objective overall response rate (complete response + partial response) was 68.1% in the S-1 group, and 73.8% the DP group (p = 0.497). The 3-year overall survival was 34.7% in the S-1 group, and 38.8% in the DP group (p = 0.422). The 3-year progression free survival in the DP group was higher than that in the S-1 group but without significant difference (33.0% vs. 25.0%, p = 0.275). Conclusion CCRT with S-1 is not inferior to CCRT with docetaxel and cisplatin and is better tolerated in in elderly patients with locally advanced ESCC.

Introduction: Patients with advanced pancreatic cancer have a poor prognosis. FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GnP) have been established as first-line treatment, but they have not been confirmed as second-line treatment after FFX. The aim of this study was to evaluate the safety and efficacy of GnP as second-line therapy after FFX in patients with unresectable pancreatic cancer. Methods: Twenty-five patients with unresectable pancreatic cancer were enrolled. The patients were treated with GnP after FFX between September 2015 and September 2019. Tumor response, progression-free survival (PFS), overall survival (OS), and incidence of adverse events were evaluated. Results: The response rate, disease control rate, median PFS, and median OS were 12%, 96%, 5.3 months, and 15.6 months, respectively. The common grade 3 or 4 adverse events were neutropenia (76%) and anemia (16%). Conclusions: GnP after FOLFIRINOX is expected to be one of the second-line recommendations for patients with unresectable pancreatic cancer.

Background and Objectives: In recent years, the effectiveness of chemotherapy after immune checkpoint inhibitor administration has attracted attention in various cancers, including head and neck cancers. However, individual assessments of the administered chemotherapy regimens are insufficient. This study aimed to evaluate the efficacy and safety of chemotherapy after immune checkpoint inhibitor administration in recurrent metastatic head and neck cancer by focusing on a single regimen. Materials and Methods: We retrospectively reviewed clinical and radiological data from the medical records of 18 patients with recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) who received systemic chemotherapy with weekly cetuximab and paclitaxel (Cmab + PTX) after progression following immune checkpoint inhibitor (ICI) therapy. The objective response rate (ORR) and disease control rate (DCR) were assessed using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan–Meier method. Adverse events (AEs) were recorded using National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0. Results: In all patients, the ORR, DCR, median PFS, and median OS were 44.4%, 72.2%, 3.8 months, and 9.6 months, respectively. Regarding AEs, three patients developed grade 3 neutropenia. Grade 3 anemia, paronychia, asthenia, and peripheral neuropathy were observed in one patient each. There were no treatment-related deaths. Conclusions: Cmab + PTX was shown to maintain high efficacy and acceptable safety for R/M HNSCC that progressed after ICI therapy. Further research is needed to establish optimal treatment sequences and drug combinations for recurrent R/M HNSCC.

e17552 Background: In platinum-resistant ovarian cancer treatment, single-agent paclitaxel can be used alone or in combination with bevacizumab. We aimed to assess the efficacy and safety profile of a weekly paclitaxel (WP) scheme in heavily pretreated platinum-resistant high-grade serous ovarian carcinoma. Methods: We retrospectively analyzed 30 adult patients with platinum-resistant high-grade serous ovarian carcinoma treated with WP at our institution between 2015 and 2020. Patients with platinum-resistant ovarian, fallopian tube or primary carcinoma of the peritoneum who had received at least 3 doses of WP (80 mg/m2) alone or in combination with bevacizumab until disease progression or unacceptable toxicity were included in the analysis. Progression-free survival was assessed according to the Response Evaluation Criteria in Solid Tumors version 1.1. Information about toxicity was gathered from medical reports and lab tests. Kaplan-Meier curves and Log-rank test were performed for survival estimates. Results: In our sample, the median age was 68 years (IQR: 60-75) and the median number of previous lines of systemic treatment was 3 (range 1-5). 40% of patients received WP in combination with bevacizumab. The disease control rate was 60.7% (42.9% partial response and 17.8% stable disease). In the overall analysis, the median progression-free survival (mPFS) was 5.0 months (95% CI: 2.0-7.1 months). The presence of ascites significantly shortened the mPFS compared to patients without it (1.1 vs 5.1 months, p < 0.001). Even though the addition of bevacizumab to WP improved the mPFS, the difference was not statistically significant compared to WP alone (7.1 vs 4.06 months, p=0.30). Peripheral neuropathy was the most common adverse event (78% all grades, 18% grade 3). No grade 3 hematologic toxicity was registered. Treatment was discontinued in 6 patients (20%) – 4 due to peripheral neuropathy and two because of toxicoderma. Conclusions: In our sample, WP was an active and safe regimen in heavily pretreated platinum-resistant ovarian carcinoma. WP was well tolerated in elderly patients. The presence of ascites was associated to a shorter PFS in patients treated with WP compared to ascites-free patients.

Abstract To study and observe the safety and efficacy of anlotinib in the treatment of advanced osteosarcoma with metastases. We retrospectively studied patients with advanced osteosarcoma and metastases who received anlotinib treatment in our hospital from June 2018 to April 2020. All patients had received standard multimodal therapies, before taking anlotinib. Therapeutic doses of anlotinib were 12 mg for adults and 10 mg for children and adolescents once a day for 2 consecutive weeks, followed by a week of withdrawal. This 3-week cycle of treatment was continued until the tumor progressed rapidly or the patients failed to tolerate the side effects. Adverse drug reactions were recorded, and therapeutic efficacy was evaluated based on progression free survival (PFS), disease control rate (DCR), overall survival (OS), and objective response rate (ORR). The median PFS was 9.81 ± 0.9 months, and the 6-month and 10-month PFS rates were 73.3% and 33.3%, respectively. The median OS was 11.43 ± 0.58 months. No patients achieved complete response. After 6 months of treatment, the DCR and ORR were 80% and 13.3%, respectively. No drug-related deaths or Grade 4 adverse events occurred in the patients. Five patients (33.3%) had Grade 3 adverse events. The most common drug-related adverse events were hand-food syndrome, fatigue, high blood pressure, anorexia, and pneumothorax. Anlotinib had a certain curative effect on patients with advanced osteosarcoma and metastases after failure of standard treatment. The adverse events were mostly tolerable or relieved after treatment.

Abstract Background Irinotecan-based doublet chemotherapy strategy was standard second-line backbone treatment for patients with oxaliplatin‑refractory metastatic colorectal cancer(mCRC). The aim of this study was to evaluate tolerability and efficacy of raltitrexed combined with irinotecan biweekly administered as the second-line therapy for mCRC patients.Methods The study was a single-center, non-randomized, open-label phase II trial. Patients with mCRC after failure with first-line treatment of oxaliplatin and fluoropyrimidine or its derivatives were enrolled. Irinotecan (180 mg/m2) and raltitrexed (2.5 mg/m2) were given intravenously on day 1. Cycles were repeated every 2 weeks. The primary endpoint was progression-free survival, and the secondary endpoints included overall response rate, disease control rate, overall survival and treatment related adverse events. Results Between December 2012 and October 2016, 35 patients were enrolled. 33 and 35 patients were assessed for response and safety, respectively. The overall response rate (ORR) was 8.6 %, and the disease control rate (DCR) was 71.4%. The median progression-free survival (PFS) was 4.5 months (95% CI 3.8–5.2). The median overall survival was 12.0 months (95% CI 8.5–15.5). Four patients received conversion therapy to no evidence of disease (NED), and 2 patients were still alive with beyond 24 months survival. The most common grade 3/4 hematological adverse events were leukopenia (8.6%), neutropenia (5.7%). The most common grade 3/4 nonhematological adverse events were anorexia (14.3%), vomiting (14.3%), nausea (11.4%) and fatigue (8.6%). Two patients discontinued the protocol treatment because of treatment-related gastrointestinal adverse events. No one died from treatment-related events. The incidence and severity of toxicity was irrelevant to UGT1A1 status.Conclusions The combination of irinotecan with raltitrexed is an active, convenient and acceptable toxic regimen for second-line treatment for mCRC patients, which needs further study as a chemotherapy backbone to be combined with targeted agents in mCRC.Trial registration No. ChiCTR-ONC-12002767. The study was registered with the Chinese Clinical Trial Registry at 29 Octorber 2012, http://www.chictr.org.cn/index.aspx.
