Duration of second remission of Hodgkin's disease in children. Results of treatment achieved by the Polish Leukemia and Malignant Lymphoma Therapy in Children Group]

Recurrence was noted in 18.5% of 194 children, in which chemotherapy with MVPP regimen produced complete I remission. In 6 out of 36 children with recurrent disease MVPP regimen was repeated, while the remaining children were treated with B-DOPA alone or combined with MOPP regimen. Local radiotherapy was used in 17 children. The second complete remission was achieved in 30 (83.7%) children. Thirteen out of 36 patients died because of the progress of the disease (11 children), and for complications (2 children). Percentage of persisting 5- and 10-year II remissions are 58.2% and 54.6%, respectively. A 5- and 10-year survival rates in children with recurrent disease are 80.5% and 60.5%, respectively. Our relatively favourable results we associate--first of all--with the chemotherapy intensity.     

Prednisone in MOPP chemotherapy for Hodgkin's disease.

High remission rates have been produced by MOPP (mustine, vincristine, procarbazine, and prednisone) chemotherapy in patients with advanced Hodgkin''s disease, but the prednisone component has caused adverse effects in patients who have undergone radiotherapy. The remission rates and length of remission were reviewed in 211 patients with Hodgkin''s disease who received chemotherapy either with or without prednisone. In contrast to the findings of a British study, there were no significant differences in remission rates or length of remission between patients who had received prednisone and patients who had not. There were differences between the British prospective study and this retrospective one, but it is difficult to know what accounted for the substantial differences in the findings.     

Randomised trial of two-drug and four-drug maintenance chemotherapy in advanced or recurrent Hodgkin's disease. Medical Research Council's working party on lymphomas.

Between 1970 and 1975, 108 patients who presented with advanced or recurrent Hodgkin''s disease and were free of disease after six courses of chemotherapy with mustine, vinblastine, procarbazine, and prednisone (MVPP) were allocated at random to one of two regiments of maintenance treatment: either intermittent treatment with vinblastine and procarbazine or intermittent treatment with MVPP. After a median follow-up period of nearly five years there was no significant difference between the two groups in either the rate of relapse or death rate. Six of the 55 patients given the two-drug regimen died compared with 10 of the 53 given the four-drug regimen. The four-drug required hospital attendance and was less agreeable than the two-drug regimen. The efficacy of maintenance chemotherapy with the two-drug regimen was no less than that with the four-drug regimen, but the two-drug regimen had several practical advantages.     

Combination Chemotherapy in Generalized Hodgkin's Disease

Fifty-two patients with generalized Hodgkin''s disease were treated with a combination of mustine hydrochloride, vinblastine, procarbazine, and prednisolone. Complete remissions were obtained initially in six out of seven patients (86%) who had previously received no treatment, in 15 out of 19 (79%) who had had only radiotherapy in the past, and in 9 out of 26 (35%) who had previously been given chemotherapy with or without radiotherapy. Of these 30 patients in whom a complete remission was obtained 22 have been free of any symptoms or signs of disease for periods ranging from 4 to 22 months. The response to treatment was rapid, and toxicity was not a major problem, except in those who had previously been treated with cytotoxic drugs used continuously and not in courses. A comparative trial of radiotherapy and combination therapy in the treatment of Stage III Hodgkin''s disease is strongly recommended.     

Proposed regimens for chemotherapy and radiotherapy to control preliminary failures of combined therapy in Hodgkin's disease

Both regimens concern children who underwent--depending on the stage of the disease--three different therapeutical regimens: B-DOPA and/or MVPP combined with radiotherapy. Depending on the results of this treatment, each out of four saving regimens includes two types of chemotherapy: B-DOPA/CAD, MVPP/CAD, MOP-P/ABV/CAD, and MVPP/B-DOPA in case of delayed recurrence. Each cycle of chemotherapy should be introduced with high frequency. Doses of irradiation being additional method and indicated in some patients are given.     

不同放化疗模式治疗中晚期非小细胞肺癌的疗效分析

目的:探讨同步和序贯放疗联合不同化疗方案对治疗中晚期非小细胞肺癌近期疗效、远期生存及毒性反应的影响。方法:将45例III-IV期非小细胞肺癌患者随机归入两组,同步放化疗组22例;序贯放化疗组23例。全组病例依据病情分别选择艾素和顺铂、吉西他滨和顺铂、长春瑞滨和顺铂或培美曲塞和顺铂方案化疗。比较两组近期疗效、远期生存率及毒性反应。结果:同步组近期有效率为81.8%高于序贯组73.9%,但无统计学差异(P0.05);两组均有随放疗剂量增加有效率升高趋势。NP和TP方案两组近期疗效相近(P0.05)。同步组和序贯组1年生存率分别为90.9%和86.9%(P0.05);2年生存率分别为72.7%和52.2%(P0.05)。毒性反应主要为骨髓抑制、放射性食管炎和肺炎。同步组毒副反应发生率高于序贯组,但无统计学差异(P0.05)。结论:同步放化疗治疗中晚期非小细胞肺癌近期疗效及远期生存率有优于序贯放化疗的趋势,但毒副反应发生相对增多。联合治疗模式下,分期越早,患者远期生存时间越长。近期疗效有随放疗剂量增高而提高趋势,但放疗剂量、病理类型、化疗方案等对患者远期生存无明显统计学差异。     

Treatment failures and severe complications in children with Hodgkin's disease

Therapy failures and severe complications in the treatment of 46 children affected with Hodgkin's disease are reported. All children were treated with polychemotherapy (modified MVPP scheme) and radiotherapy (high voltage therapy X-ray 210 KV; involved field radiotherapy). 42 patients came into a complete remission, with a median of 58 months in 37 patients (10--97 months). 6 patients 14.3%) suffered from a recidive, 5 of them came into a second remission. Life-threatening infections appeared in 3 patients. After 9 MVPP cycles an encephalopathy appeared in 2 boys, one of them died. After local radiotherapy a severe laryngitis developed in two patients. An azoospermia existed in 6 adolescent boys examined.     

Efficacy and Toxicity of Different Chemotherapy Regimens in the Treatment of Advanced or Metastatic Pancreatic Cancer: A Network Meta‐Analysis

Objective A network meta‐analysis was conducted to compare the efficacy and toxicity of different chemotherapy regimens in treating advanced or metastatic pancreatic cancer (PC). PubMed, Cochrane Library and EMBASE databases from inception to June 2016 were searched. A combination of direct and indirect evidences was referred to for calculating the weighted mean difference (WMD) or the odds ratio (OR) and to establish surface under the cumulative ranking (SUCRA) curves, so as to evaluate the efficacy and toxicity of different chemotherapy regimens in treating advanced or metastatic PC. Twenty randomized controlled trials were enrolled. Twelve chemotherapy regimens included Gemcitabine, S‐1 (Tegafur), Gemcitabine + Cisplatin, Gemcitabine + Capecitabine, Gemcitabine + S‐1, Gemcitabine + 5‐FU (5‐fluorouracil), Gemcitabine + Exatecan, Gemcitabine + Irinotecan, Gemcitabine + Nab‐paclitaxel, FOLFIRINOX (Oxaliplatin + Irinotecan + Fluorouracil + Leucovorin), Gemcitabine + Oxaliplatin, and Gemcitabine + Pemetrexed. Higher overall response rate (ORR) was observed in patients treated with the gemcitabine + S‐1 and FOLFIRINO regimens. Thrombocytopenia reduced in patients treated with the S‐1 regimen. The Gemcitabine + S‐1 and FOLFIRINO regimens had better short‐ and long‐term efficacies than the other regimens; S‐1 regimen had the lowest hematologic toxicity, while Gemcitabine + Nab‐paclitaxel, FOLFIRINOX, and Gemcitabine + Pemetrexed regimens had higher incidence of non‐hematologic toxicity among twelve chemotherapy regimens. The efficacy of Gemcitabine + S‐1 and FOLFIRINOX regimens may be better in treating patients with advanced or metastatic pancreatic cancer, while FOLFIRINOX and Gemcitabine + Pemetrexed regimens may have relatively higher incidence of toxicity than other regimens.

Efficacy of lomustine, teniposide, doxorubicin, bleomycin and prednisone (LTABP) or adriamycin, bleomycin, vinblastine and dacarbazine (ABVD) in the treatment of malignant lymphogranulomatosis resistant to MOPP]

LTABP regimen was applied to 18 patients in IIB and IV stage of malignant lymphogranulomatosis resistant to MOPP. The obtained results were compared with historical control group of 18 patients with similar stage of the disease treated according to ABVD regimen. In both regimens courses were repeated every 28 days or more rarely, when leucopenia and thrombocytopenia prolonged. Only patients who had received at least 3 courses were analysed. In the LTABP group the complete remission was obtained in 10 cases (55%) while partial remission in 6 (33%). In the group treated with ABVD complete remission was obtained in 4 cases (22%) and partial in 9 cases (50%). In the LTABP group 11 patients are still alive and remain in complete remission, while in ABVD group--4 patients. The most frequent side effects in both groups included leucopenia, thrombocytopenia and symptoms of gastrointestinal intolerance. The LTABP regiment allows to obtain higher percentage of the complete remission than ABVD.     

Improved combination chemotherapy in advanced gastric cancer.

Thirty-five patients with advanced-stage metastatic or unresectable gastric adenocarcinoma were given combination chemotherapy consisting of fluorouracil, doxorubicin, and 1,3-bis (2-chlorbethyl)-1-nitrosourea. Two patients achieved complete remission and 16 partial remission to give an overall response rate of 52%. Six further patients (17%) had stable disease, while in 11 (31%) the disease showed clear-cut progression despite treatment. The only pretreatment factors that suggested poor prognosis were poor initial patient performance and the stomach as the predominant site of disease. Patients responding to treatment had a significantly longer time to relapse (median 48 weeks) than patients with stable disease (median 16 weeks) and a significantly improved survival time (medians, 52 weeks with 30% of patients'' living at 88 weeks and 32 weeks with all dead at 64 weeks respectively). Comparing these results with those in other reports indicated that the three-drug combination chemotherapy consisting of fluorouracil, doxorubicin, and either a nitrosourea or mitomycin was superior to single and two-drug regimens and currently represents the optimum treatment for advanced-stage gastric cancer. Gastric adenocarcinoma should now be considered to be a gastrointestinal malignancy that is relatively susceptible to chemotherapy, and studies of these improved chemotherapeutic regimens as post-surgical adjuvants may lead to further improvements in prognosis.     

Secondary neoplasms in two children with Hodgkin's disease]

In two out of 59 children with Hodgkin's disease treated with MVPP regimen combined with local irradiation and followed up over 10 years the secondary neoplasms were detected, i.e. in 3.4% with persisting remission of the underlying disease. Chondrosarcoma was diagnosed in one patient in the field of irradiation (after 13 years). This patient died. In the second patient two different tumors (squamous epithelioma and fibrosarcoma) developed after 7 and 9 years following irradiation of two different areas. Actually, there are not any symptoms in this female patients (working). To decrease the incidence of these serious complications of Hodgkin's disease treatment regimens introduced by the Polish Pediatric Leukemia Study Group since 1988, the use of alkylating agents in limited, and the dose of local irradiation is decreased.

目的：探讨晚期结肠癌癌组织中核苷酸切除修复交叉互补基因1（excisionrepaircross—complementinggenel,ERCCl）~O表达状况及其与患者临床病理特征、奥沙利铂方案化疗疗效及预后之间的关系。方法：采用免疫组化方法检测晚期结肠癌癌组织中ERCCl蛋白表达状况。结果：晚期结肠癌癌组织中ERCCl表达阳性表达率为45．1％。ERCCl蛋白的表达状况与患者的性别、年龄、肿瘤部位、分化程度及病理类型均无关（P〉0．05）。ERCCl蛋白表达阴性患者奥沙利铂方案化疗有效率为56．O％高于表达阳性患者的34．1％（P。0．037）,并且接受化疗后表达阴性患者中位生存期为19个月高于表达阳性患者的14个月（P=0．016）。结论：ERCCl蛋白表达阴性的晚期结肠癌患者接受奥沙利铂方案化疗有效率较阴性患者高并有生存受益,ERCCl的表达状态可作为晚期结肠癌化疗方案的选择及预后判断的指标。     

Long-term follow-up after relapses in children with Hodgkin's disease

In the years 1969-1980, 68 children with Hodgkin's disease were subjected to a combined MVPP and radiotherapy. Remissions were obtained in 64 patients, and relapses occurred in 11 children. The treatment of relapse consisted in administration of B-DOPA alone or alternatively with MVPP combined with radiotherapy (in 7 out of 11 patients). The patients were recycled every 2-3 weeks which, with other modifications of chemotherapy, allowed for the completion of the six first cycles within the period of 4,5 to 7 months. A relapse caused death of one child, and two others demonstrated further relapses. At present eight children have been showing disease-free survival following a relapse for the period of 29+ to 152+ (median, 94.5 months). The authors concluded that in patients with relapses of Hodgkin's disease the decisive role rests upon aggressive chemotherapy (high frequency of cycles).

Retrospective Analysis of 234 Nasopharyngeal Carcinoma Patients with Distant Metastasis at Initial Diagnosis: Therapeutic Approaches and Prognostic Factors

Purpose

The purpose of this retrospective study was to identify the independent prognostic factors and optimize the treatment for nasopharyngeal carcinoma (NPC) patients with distant metastasis at initial diagnosis.

Methods

A total of 234 patients referred between January 2001 and December 2010 were retrospectively analyzed. Among the 234 patients, 94 patients received chemotherapy alone (CT), and 140 patients received chemoradiotherapy (CRT). Clinical features, laboratory parameters and treatment modality were examined with univariate and multivariate analyses.

Results

The median overall survival (OS) time was 22 months (range, 2-125 months), and the 1-year, 2-year, 3-year overall survival rates were 82.2%, 51.3% and 34.1%. The overall response and disease control rates of metastatic lesions after chemotherapy were 56.0% and 89.8%. The factors associated with poor response were karnofsky performance score (KPS) <80, liver metastasis, lactate dehydrogenase (LDH)>245 IU/L, and number of chemotherapy cycles <4. The 3-year OS of patients receiving CRT was higher than those receiving CT alone (48.2% vs. 12.4%, p<0.001). Subgroup analysis showed that significantly improved survival was also achieved by radiotherapy of the primary tumor in patients who achieved complete remission (CR)/partial remission (PR) or stable disease (SD) of metastatic lesions after chemotherapy. Significant independent prognostic factors of OS were KPS, liver metastasis, levels of LDH, and multiple metastases. Treatment modality, response to chemotherapy and chemotherapy cycles were also associated with OS.

Conclusion

A combination of radiotherapy and chemotherapy seems to have survival benefits for selected patients with distant metastases at initial diagnosis. Clinical and laboratory characteristics can help to guide treatment selection. Prospective randomized studies are needed to confirm the result.     

Combination chemotherapy for acute lymphoblastic leukaemia in adults.

Fifty-one adults with acute lymphoblastic leukaemia were entered into a trial of intense initial chemotherapy and early "prophylaxis" of the central nervous system (CNS). Initial treatment with OPAL (Oncovin (vincristine), prednisolone, adriamycin (doxorubicin), and L-asparaginase (colaspase)) followed by craniospinal or cranial irradiation and intrathecal methotrexate produced remission in 36 patients (71%). Seventeen of these patients relapsed three to 18 months after the start of remission; the remainder had been in remission for 12 to 52 months by the end of the study. The predicted median duration of complete remission was 18.5 months. None of the four patients who initially had clinical evidence of CNS disease, three of whom also had leukaemic cells identical to those found in Burkitt''s lymphoma, achieved remission. Those patients who initially had hepatomegaly or splenomegaly had a shorter remission than those without. The predicted median survival was 27 months in those who achieved complete remission, one month in those who did not, and 21 months overall. The addition of colaspase and doxorubicin to vincristine and prednisolone and the use of early CNS treatment clearly improved the remission rate among adults with acute lymphoblastic leukaemia, though the presence and length of remission was affected by the extent of disease at presentation. Burkitt-like leukaemia, which had a poor prognosis, is probably a separate disease and may benefit from a different therapeutic approach.     

Muscle-invasive bladder cancer treated with TURB followed by concomitant boost with small reduction of radiotherapy field with or without of chemotherapy

Aim

To evaluate the clinical outcome and toxicity of the treatment of muscle-invasive bladder cancer (MIBC) that combined transurethral resection of bladder tumor (TURB) with “concomitant boost” radiotherapy delivered over a shortened overall treatment time of 5 weeks, with or without concurrent chemotherapy.

Background

Local control of MIBC by bladder-sparing approach is unsatisfactory. In order to improve the effectiveness of radiotherapy, we have designed a protocol that combines TURB with a non-conventionally fractionated radiotherapy “concomitant boost”.

Materials and methods

Between 2004 and 2010, 73 patients with MIBC cT2-4aN0M0, were treated with “concomitant boost” radiotherapy. The whole bladder with a 2–3 cm margin was irradiated with fractions of 1.8 Gy to a dose of 45 Gy, with a “concomitant boost” to the bladder with 1–1.5 cm margin, during the last two weeks of treatment, as a second fraction of 1.5 Gy, to a total dose of 60 Gy. Radiochemotherapy using mostly cisplatin was delivered in 42/73(58%) patients, 31/73(42%) patients received radiotherapy alone.

Results

Acute genitourinary toxicity of G3 was scored in 3/73(4%) patients. Late gastrointestinal toxicity higher than G2 and genitourinary higher than G3 were not reported. Complete remission was achieved in 48/73(66%), partial remission in 17/73(23%), and stabilization disease in 8/73(11%) patients. Three- and five-year overall, disease specific and invasive locoregional disease-free survival rates were 65% and 52%, 70% and 59%, 52% and 43%, respectively.

Conclusions

An organ-sparing approach using TURB followed by radio(chemo)therapy with “concomitant boost” in patients with MIBC allows to obtain long-term survival with acceptable toxicity.     

ATO/ATRA/Anthracycline-Chemotherapy Sequential Consolidation Achieves Long-Term Efficacy in Primary Acute Promyelocytic Leukemia

The combination of all-trans retinoic acid (ATRA) and arsenic trioxide (As₂O₃, ATO) has been effective in obtaining high clinical complete remission (CR) rates in acute promyelocytic leukemia (APL), but the long-term efficacy and safety among newly diagnosed APL patients are unclear. In this retrospective study, total 45 newly diagnosed APL patients received ATRA/chemotherapy combination regimen to induce remission. Among them, 43 patients (95.6%) achieved complete remission (CR) after induction therapy, followed by ATO/ATRA/anthracycline-based chemotherapy sequential consolidation treatment with a median follow-up of 55 months. In these patients, the estimated overall survival (OS) and the relapse-free survival (RFS) were 94.4%±3.9% and 94.6±3.7%, respectively. The toxicity profile was mild and reversible. No secondary carcinoma was observed. These results demonstrated the high efficacy and minimal toxicity of ATO/ATRA/anthracycline-based chemotherapy sequential consolidation treatment for newly diagnosed APL in long-term follow-up, suggesting a potential frontline therapy for APL.     

血清cfDNA、VEGFA与晚期胃癌患者化疗疗效和预后的关系研究

摘要 目的：研究血清循环游离脱氧核糖核酸（cfDNA）、血管内皮生长因子A（VEGFA）与晚期胃癌患者化疗疗效和预后的关系。方法：选取2018年6月~2020年6月在空军第九八六医院接受含奥沙利铂方案化疗的晚期胃癌患者108例,所有患者均接受含奥沙利铂方案化疗,化疗2个周期后,根据实体瘤疗效评价标准（RECIST）1.1版评估疗效分为敏感组和不敏感组,比较两组血清cfDNA、VEGFA水平;随访24个月,Kaplan-Meier生存曲线分析血清cfDNA、VEGFA高表达和低表达组的总生存期（OS）,采用Cox风险比例模型进行预后多因素分析。结果：不敏感组血清cfDNA、VEGFA水平显著高于敏感组（P＜0.05）。cfDNA、VEGFA高表达组患者中位OS均明显短于cfDNA、VEGFA低表达组（P＜0.05）。Cox回归模型单因素分析显示,性别、年龄、部位与晚期胃癌预后无关（P＞0.05）,而TNM分期Ⅳ期、分化程度低分化、有淋巴结转移、化疗疗效不敏感、cfDNA高水平、VEGFA高水平与晚期胃癌预后差显著相关（P＜0.05）。Cox回归模型多因素分析显示,淋巴结转移、化疗疗效不敏感及cfDNA、VEGFA水平高是晚期胃癌患者预后的危险因素（P＜0.05）。结论：血清cfDNA、VEGFA水平检测有助于晚期胃癌患者化疗疗效监测和预后评估。
