目的:比较血小板生成素与白介素-11治疗胃癌患者术后化疗血小板减少症的时效和安全性。方法:术后辅助化疗出现血小板计数低于75×109/L的进展期胃癌患者68例,将其分为TPO组与IL-11组,分别为35例和33例。分别皮下注射rhTPO 15000U,每日1次;rhIL-11 1.5 mg,每日1次,当血小板计数125×109/L或比用药前上升50×109/L,即停止给药,疗程最长为14天。每3天抽取外周静脉血2 m L,通过全自动血液分析仪测定血小板计数,密切观察出现的不良反应并记录。比较两组患者不同临床病理资料、血小板计数、血小板计数升至75×109/L和125×109/L的时程、药物不良反应。结果:两组患者年龄、性别、化疗方案、血小板最低值出现的化疗周期及临床病理分期的比较均没有统计学差异(P值均0.05)。TPO组与IL-11组血小板动态值的比较,第9天出现显著差异(P=0.032)。TPO组与IL-11组血小板计数恢复至75×109/L和125×109/L所需的时间,有显著差异(P=0.041,P=0.013)。TPO组中,有3例(8.6%)患者发生不良反应,IL-11组中,有13例(39.4%)患者发生不良反应,TPO组患者出现的不良反应少且较轻微(P=0.006)。结论:rhTPO治疗胃癌患者术后化疗血小板减少症时效快,安全性好。     

莫西沙星联合用药方案对耐多药肺结核患者血清游离氨基酸和免疫功能的影响

目的:探讨莫西沙星联合用药方案对耐多药肺结核(MDR-TB)患者血清游离氨基酸和免疫功能的影响。方法:选取2015年9月到2018年1月期间我院收治的90例MDR-TB患者,根据乱数表法将患者分为研究组(n=45)、对照组(n=45),其中对照组给予左氧氟沙星联合常规化疗治疗,研究组则给予莫西沙星联合常规化疗治疗,比较两组临床疗效、痰菌转阴率、病灶吸收率、空洞闭合率、血清游离氨基酸和免疫功能,记录两组治疗期间不良反应情况。结果:研究组治疗18个月后的临床总有效率为71.11%(32/45),高于对照组的46.67%(21/45)(P0.05)。研究组治疗18个月后痰菌转阴率、病灶吸收率、空洞闭合率均较对照组高(P0.05)。两组患者治疗18个月后CD4+、免疫球蛋白A(Ig A)、免疫球蛋白G(Ig G)均升高,CD8+降低(P0.05),研究组治疗18个月后CD4+、Ig A、Ig G高于对照组,而CD8+低于对照组(P0.05)。两组治疗18个月后缬氨酸、谷氨酸均升高,且研究组高于对照组(P0.05)。两组患者总不良反应发生率比较无明显差异(P0.05)。结论:莫西沙星联合常规化疗治疗MDR-TB的疗效确切,可有效改善患者血清游离氨基酸水平,提高机体免疫功能,同时不增加不良反应发生率。     

肺癌患者生活质量调查及化疗期间发生抑郁的影响因素分析

目的:探讨肺癌患者化疗前后生活质量的变化及化疗期间发生抑郁的影响因素。方法:将2015年1月～2019年12月我院收治的80例肺癌患者纳入研究。所有患者均接受化疗干预,采用健康状况调查简表(SF-36)评分评估患者化疗前后生活质量,以抑郁自评量表(SDS)评估患者抑郁发生情况。对肺癌患者化疗期间发生抑郁的影响因素进行单因素以及多因素Logistic回归分析。结果:化疗后患者的各项生活质量评分均低于化疗前(P0.05)。80例肺癌患者化疗期间出现46例抑郁症,抑郁症发生率为57.50%。经单因素分析发现:性别、受教育程度、家庭月收入、疼痛程度、知晓病情均与肺癌患者化疗期间发生抑郁有关(P0.05)。经多因素Logistic回归分析可得:女性、家庭月收入2500元、Ⅰ度及以上疼痛、知晓病情均是肺癌患者化疗期间发生抑郁的独立危险因素(OR=7.295、1.692、3.952、4.015,P0.05)。结论:化疗会在一定程度上降低肺癌患者的生活质量,同时会增加患者抑郁症发生风险,女性、家庭月收入2500元、Ⅰ度及以上疼痛、知晓病情均是肺癌患者化疗期间发生抑郁的独立危险因素。     

COVID-19 pandemic and patients with cancer: The protocol of a Clinical Oncology center in Tehran,Iran

AimTo provide recommendations for the management of patients with cancer in the COVID-19 era.BackgroundThe current global pandemic of COVID-19 has severely impacted global healthcare systems. Several groups of people are considered high-risk for SARS-CoV-2 infection, including patients with cancer. Therefore, protocols for the better management of these patients during this viral pandemic are necessary. So far, several protocols have been presented regarding the management of patients with cancer during the COVID-19 pandemic. However, none of them points to a developing country with limited logistics and facilities.MethodsIn this review, we have provided a summary of recommendations on the management of patients with cancer during the COVID-19 pandemic based on our experience in Shohada-e Tajrish Hospital, Iran.ResultsWe recommend that patients with cancer should be managed in an individualized manner during the COVID-19 pandemic.ConclusionsOur recommendation provides a guide for oncology centers of developing countries for better management of cancer.     

Improved long-term results of intensity-modulated radiotherapy for a non-endemic European nasopharyngeal carcinoma cohort: single-center retrospective study

PurposeReport our matured outcomes of European nasopharyngeal carcinoma (NPC) treatment from a non-endemic region in the IMRT era.MethodsWe reviewed 109 consecutive patients with biopsy proven NPC treated between 2009 and 2013. All received IMRT as per RTOG 0615. Toxicity was scored accordingly to CTCAE 4.03. Platinum-based chemotherapy was delivered following the Intergroup 0099.ResultsMedian age of 53 years; 97% Caucasian; 74% male; 72% WHO grade III; 43% T1; 14% T2; 18% T3, 25% T4; 17% N0; 17% N1; 39% N2; 27% N3. Compliance to adjuvant chemotherapy was 88%. With a median follow up of 56 months, the 4-year local control was 90.2% (88.6% for T1; 100% for T2; 85% for T3; and 91.7% for T4), the 4-year distant metastases-free survival was 86% and an overall survival rate was 77%. Local control and survival were better in G3 (p < 0.001 and p = 0.032, respectively). Xerostomia was the most frequent late toxicity in 55% (n = 60). Hypothyroidism requiring hormonal reposition occurred in 15.5% (n = 17). From the 36 deaths, 20 were due to distant metastases, 3 grade 5 toxicity, 2 from local progression, 5 non-cancer deaths and unknown cause in the remaining 6. On multivariable analysis, age (p = 0.017), local recurrence and distant metastases were associated with death (p < 0.001, both).ConclusionOur matured data from the IMRT era showed a major improvement from our 3D cohort series reaching excellent local and regional control, even in T4. Local recurrences, despite few, and distant metastases were correlated with the risk of death.     

High-dose neoadjuvant chemoradiotherapy versus chemotherapy alone followed by surgery in potentially-resectable stage IIIA-N2 NSCLC. A multi-institutional retrospective study by the Oncologic Group for the Study of Lung Cancer (Spanish Radiation Oncology Society)

BackgroundThe optimal induction treatment in potentially-resectable stage IIIA-N2 NSCLC remains undefined.AimTo compare neoadjuvant high-dose chemoradiotherapy (CRT) to neoadjuvant chemotherapy (CHT) in patients with resectable, stage IIIA-N2 non-small-cell lung cancer (NSCLC).MethodsRetrospective, multicentre study of 99 patients diagnosed with stage cT1-T3N2M0 NSCLC who underwent neoadjuvant treatment (high-dose CRT or CHT) followed by surgery between January 2005 and December 2014.Results47 patients (47.5%) underwent CRT and 52 (52.5%) CHT, with a median follow-up of 41 months. Surgery consisted of lobectomy (87.2% and 82.7%, in the CRT and CHT groups, respectively) or pneumonectomy (12.8% vs. 17.3%). Nodal downstaging (to N1/N0) and Pathologic complete response (pCR; pT0pN0) rates were significantly higher in the CRT group (89.4% vs. 57.7% and 46.8% vs. 7.7%, respectively; p < 0.001)). Locoregional recurrence was significantly lower in the CRT group (8.5% vs. 13.5%; p = 0.047) but distant recurrence rates were similar in the two groups. Median PFS was 45 months (CHT) vs. “not reached” (CRT). Median OS was similar: 61 vs. 56 months (p = 0.803). No differences in grade ≥3 toxicity were observed. On the Cox regression analysis, advanced pT stage was associated with worse OS and PFS (p < 0.001) and persistent N2 disease (p = 0.002) was associated with worse PFS.ConclusionsCompared to neoadjuvant chemotherapy alone, a higher proportion of patients treated with preoperative CRT achieved nodal downstaging and pCR with better locoregional control. However, there were no differences in survival. More studies are needed to know the optimal treatment of these patients.     

Focus: Zoonotic Disease: New Series of Imidazoles Showed Promising Growth Inhibitory and Curative Potential Against Trypanosoma Infection

The Trypanosoma spp. cause animal and human trypanosomiasis characterized with appreciable health and economic burden mostly in developing nations. There is currently no effective therapy for this parasitic disease, due to poor drug efficacy, drug resistance, and unwanted toxicity, etc. Therefore, new anti-Trypanosoma agents are urgently needed. This study explored new series of imidazoles for anti-Trypanosoma properties in vitro and in vivo. The imidazoles showed moderate to strong and specific action against growth of T. congolense. For example, the efficacy of the imidazole compounds to restrict Trypanosoma growth in vitro was ≥ 12-fold specific towards T. congolense relative to the mammalian cells. Additionally, the in vivo study revealed that the imidazoles exhibited promising anti-Trypanosoma efficacy corroborating the in vitro anti-parasite capacity. In particular, three imidazole compounds (C1, C6, and C8) not only cleared the systemic parasite burden but cured infected rats after no death was recorded. On the other hand, the remaining five imidazole compounds (C2, C3, C4, C5, and C7) drastically reduced the systemic parasite load while extending survival time of the infected rats by 14 days as compared with control. Untreated control died 3 days post-infection, while the rats treated with diminazene aceturate were cured comparable to the results obtained for C1, C6, and C8. In conclusion, this is the first study demonstrating the potential of these new series of imidazoles to clear the systemic parasite burden in infected rats. Furthermore, a high selectivity index of imidazoles towards T. congolense in vitro and the oral LD₅₀ in rats support anti-parasite specific action. Together, findings support the anti-parasitic prospects of the new series of imidazole derivatives.
