Metastatic squamous cell carcinoma of an unknown primary tumor localized to the neck.

68 patients with metastatic squamous-cell carcinoma (SCC) of an unknown primary tumor localized to the neck were treated between 1981 and 1990. There were 11 patients treated with radiotherapy alone, 24 patients treated with surgery and radiotherapy and 33 patients treated with radiotherapy and chemotherapy. Male to female ratio was 1.9:1 and the median age was 55 years (range, 33 to 71 years). 41 (61%) patients had N3 disease, 18 (26%) patients had N2 disease and 9 (13%) patients had N1 disease. The majority of N3 patients were treated with radiotherapy + chemotherapy (n = 17) and surgery + radiotherapy (n = 17). The complete response (CR) to radiotherapy + chemotherapy was 73% with 19 patients having no evidence of disease currently. The median survival time (MST of this group was 34+ months. Of the 35 patients who had surgery and/or radiotherapy, 7 (20%) currently have no evident disease. The MST of these two groups (combined) was 22 months. Patients with N3 disease who received radiotherapy + chemotherapy had a higher CR rate and longer MST when compared with those without chemotherapy.     

Synergic effect of cisplatin, Adriamycin, and cyclophosphamide combination chemotherapy and radiotherapy in non-small cell lung cancer

61 patients with inoperable non-small cell lung cancer were treated by combination chemotherapy with cisplatin, Adriamycin and cyclophosphamide. 23 patients received radiotherapy in addition to the chemotherapy. 49 out of 55 adequately treated patients were evaluable for tumor response. Of 29 patients who received chemotherapy alone, 6 (21%) achieved partial responses. Of 20 patients who received combined chemotherapy and radiotherapy, 16 (80%) achieved complete or partial responses. The median survival time was 18 months for 22 patients treated with combined therapies.     

Ifosfamide, etoposide, and thoracic irradiation therapy in 163 patients with unresectable small cell lung cancer

One hundred sixty-three patients with small cell lung cancer were treated with six courses, at 3-week intervals, of ifosfamide (5 g/m2) with mesna and etoposide. Thoracic radiotherapy was delivered to the limited stage (LS) patients. The complete response rate (CR, determined clinically and radiologically) was 76% for the 78 LS patients with a further 14% partial response (PR). The majority of the CRs were confirmed on a follow-up bronchoscopy. The CR rate was 27% for extensive stage (ES) patients with another 38% undergoing a partial response. The median survival for LS patients was 11 months, (16 months for CR confirmed by rebronchoscopy) and 8 months for ES patients. The 2-year actuarial survival for LS patients is 27%, follow-up ranges from 12 months to 30 months with a median of 22 months. Toxicity was not severe for the patient population, of whom only 20% had a good performance status before chemotherapy. Parental antibiotics were required on 4% of all 844 chemotherapy courses and 12% of courses were delayed due to side effects. The majority of responses occurred within the first two courses of chemotherapy and there was a corresponding improvement in the patients' symptoms and performance status. The regimen produced rapid tumor response with corresponding improvement in symptoms without marked toxicity and allowed further treatment development.     

Metastatic Squamous Cell Carcinoma of an Unknown Primary Tumor Localized to the Neck

68 patients with metastatic squamous-cell carcinoma (SCC) of an unknown primary tumor localized to the neck were treated between 1981 and 1990. There were 11 patients treated with radiotherapy alone, 24 patients treated with surgery and radiotherapy and 33 patients treated with radiotherapy and chemotherapy. Male to female ratio was 1.9 : 1 and the median age was 55 years (range, 33 to 71 years). 41 (61%) patients had N3 disease, 18 (26%) patients had N2 disease and 9 (13%) patients had N1 disease. The majority of N3 patients were treated with radiotherapy + chemotherapy (n=17) and surgery + radiotherapy (n=17). The complete response (CR) to radiotherapy + chemotherapy was 73% with 19 patients having no evidence of disease currently. The median survival time (MST of this group was 34+ months. Of the 35 patients who had surgery and/or radiotherapy, 7 (20%) currently have no evident disease. The MST of these two groups (combined) was 22 months. Patients with N3 disease who received radiotherapy + chemotherapy had a higher CR rate and longer MST when compared with those without chemotherapy.     

Role of thoracic radiotherapy combined with chemotherapy in limited stage small cell lung cancer (SCLC). A randomized multicenter phase III trial

We initiated a prospective randomized multicenter trial to clarify the role of radiotherapy in the treatment of the primary tumor in small cell lung cancer stage limited disease. Patients were randomized to receive only chemotherapy (n = 27), or chemotherapy and radiotherapy of 30 Gy (n = 34) or chemotherapy and radiotherapy of 50 Gy (n = 30). Radiotherapy was administered after the third chemotherapy cycle. All patients received prophylactic total-brain irradiation of 30 Gy. The chemotherapy consisted of 6 cycles of adriamycin, cyclophosphamide and vincristin (ACO). 415 patients entered the trial. According to eligibility criteria 97 patients were randomized and 91 patients were evaluable for response. The total response rate (CR and PR) was 69% not being statistically different between all groups. No differences in survival time were observed between patients receiving 30 Gy (median = 13.5 months) and those receiving 50 Gy (median = 12.4 months). However patients treated with radiotherapy and chemotherapy showed a statistically significant improvement of survival time compared to patients receiving chemotherapy alone (median = 9.7 months).     

局限期小细胞肺癌诱导化疗疗效与放疗时机的关系探讨

  目的   :探讨局限期小细胞肺癌（limited-disease small cell lung cancer,LSCLC）诱导化疗疗效是否会影响放疗时机的选择。   方法   分析天津医科大学肿瘤医院2009年2月至2011年4月间诱导化疗后行放疗的148例LSCLC患者临床资料,根据RE? CIST标准将2~3个周期诱导化疗后的疗效分为完全缓解、部分缓解、病情稳定和疾病进展,化疗后有效包括完全缓解和部分缓解。根据诱导化疗后是否直接行放疗将患者分为早放疗组和晚放疗组。Kaplan-Meier法进行生存分析,组间差异采用Log-rank检验。   结果   全组患者的中位生存期（overall survival,OS）为22.8个月,中位无进展生存期（progression-free survival,PFS）为13.0个月。早放疗组和晚放疗患者的中位OS分别为34.0个月和18.0个月（P=0.012）,中位PFS分别为16.8个月和10.9个月（P=0.019）。两组分析发现,2~3个周期诱导化疗后有效的患者,早放疗组和晚放疗组的中位OS分别为36.9个月和22.8个月（P=0.043）,PFS分别为19.4个月和11.7个月（P=0.011）;诱导化疗后无效的患者,两组的中位OS分别为18.0个月和9.5个月（P=0.015）,中位PFS分别为12.4个月和10.3个月（P=0.566）。   结论   局限期小细胞肺癌行2~3个周期诱导化疗后无论是否有效,都应该尽快开始放疗。      

Combined antiestrogen and cytotoxic therapy with pseudomonas vaccine immunotherapy for metastatic breast cancer. A prospective, randomized trial

One hundred thirty-three consecutive, previously untreated patients who had metastatic breast cancer were treated with a combination of 5-fluorouracil, doxorubicin (Adriamycin), and cyclophosphamide (FAC). They were randomly assigned to receive nonspecific immunotherapy with a heptavalent pseudomonas vaccine. Sixty-five patients were treated with pseudomonas vaccine, whereas 68 did not receive immunotherapy. In addition, all patients with estrogen receptor-positive tumors or tumors with an estrogen receptor status were also treated with tamoxifen. To allow clinical assessment of hormone sensitivity in vivo, tamoxifen was started 6 weeks before chemotherapy except in patients who had life-threatening disease. After the initial 6 weeks of tamoxifen, 3% of patients had achieved a complete remission, 9% a partial remission, while 16% achieved a minor response. The maximum response after tamoxifen and chemotherapy included complete remissions in 20% of patients and partial remissions in 61% of patients for an overall remission rate of 81%. The median response duration was 15 months, and the median survival time, 27 months. There were no differences in remission rate, remission duration, or survival time between the groups treated with or without pseudomonas vaccine. Eleven patients with limited metastatic disease received radiotherapy consolidation to initially involved sites. In these patients the median time from radiotherapy to progression of disease was 33 months, and the median survival time was 46 months. We conclude that nonspecific immunotherapy with pseudomonas vaccine failed to increase remission rate or survival time. Furthermore, the addition of tamoxifen to FAC chemotherapy did not improve the remission rate or duration compared to a recent, historical control group of patients treated with only FAC chemotherapy.

目的 研究拟分析T4b期食管鳞癌接受同期放化疗的临床疗效及治疗并发症,并探讨临床相关因素对预后的影响。方法 回顾分析我院2010-2015年接受同期放化疗的143例T4b期胸段食管鳞癌患者,其中71%患者肿瘤侵犯气管或支气管,44%侵犯胸主动脉或大血管。放疗中位剂量为60 Gy (44~68 Gy),常规分割,其中69例(48%)采用3DCRT,余74例(52%)采用IMRT;化疗均采用以铂类为基础的化疗方案。根据Kaplan-Meier法进行生存分析,Logrank检验差异,Cox回归模型进行多因素分析。结果 全组患者的中位生存期为12.2个月,2、3年生存率分别为34%、29%。51例(36%)患者在治疗期间或放疗后3个月内发生≥2 级严重并发症,包括食管瘘42例、肺炎6例、食管出血3例。发生、未发生严重并发症患者的中位生存期分别为6.9、20.4个月(P<0.01)。多因素分析显示TNM分期、是否出现严重并发症是影响总生存的独立预后因素。结论 T4b期胸段食管鳞癌同期放化疗的疗效满意,但出现≥2级严重并发症的风险很高。     

不同放化疗组合方案对广泛期SCLC预后影响

目的 探讨不同放化疗组合方案对广泛期SCLC预后的影响。方法 回顾分析2011—2015年收治的322例广泛期SCLC患者,均接受依托泊苷+顺铂或卡铂标准方案化疗;根据RECIST标准将化疗后疗效分为CR、PR、SD、PD,排除化疗后进展的90例,共入组232例。根据化疗有效后是否行放疗将患者分为放疗组(187例)和无放疗组(45例)。根据放疗的早晚分为早放疗组(化疗≤3个周期接受放疗,65例)和晚放疗组(化疗>3个周期接受放疗,122例)。根据放疗和化疗顺序分为同步放化疗组(45例)和序贯放化疗组(142例)。Kaplan-Meier计算生存率,Logrank检验差异,Cox模型多因素预后分析。结果 中位OS、PFS、LRFS全组分别为13.2、 8.7、14.6个月;无放疗组分别为 8.7、5.6、5.9个月,有放疗组分别为15.0、9.8、19.2个月(P=0.00、0.00、0.00);早放疗组分别15.4、8.0、19.2个月,晚放疗组分别为14.6、10.8、18.1个月(P=0.720、0.426、0.981);同步放化疗组分别为19.4、10.8、19.8个月,序贯放化疗组分别为13.8、9.8、17.8个月(P=0.036、0.656、0.768)。接受放疗患者不良反应较无放疗患者增加(P=0.038),但≥3级严重不良反应相似(P=0.126)。     

Carboplatin, ifosfamide and etoposide with mid-course vincristine and thoracic radiotherapy for 'limited' stage small cell carcinoma of the bronchus

Forty-two patients with small cell lung cancer were treated with a combination of carboplatin, ifosfamide and etoposide. Vincristine was given on day 14 of each course, the courses being repeated every 28 days for a maximum of six. Thoracic radiotherapy was given 4 weeks after the last course of chemotherapy but no prophylactic cranial radiotherapy was administered. Thirty patients had clinically limited state disease, the remaining patients having contralateral neck lymphadenopathy and/or pleural effusions. Elevated enzyme levels (alkaline phosphatase, LDH, ALT, GGT) were noted in 69% of patients. Twenty-four patients (57%) achieved a complete response (CR) when assessed one month after the end of treatment. A further 21% of patients had a partial response (PR). Median duration of CR was 14 months and of PR 8 months. Cerebral metastases were the sole site of relapse in 13% of the CR patients. Myelosuppression was severe with a median nadir of neutropenia of 0.2 x 10(9) cells 1-1. However, 74% of the patient group received all six courses of chemotherapy and only 16 courses (7%) were delayed because of toxicity. There were three deaths associated with treatment-related neutropenia. The median survival of the total group was 14 months, with an actuarial 2 year survival of 37% and a minimum follow-up of 18 months. [A recent analysis, March 1989, demonstrated a 33%, 2 year actual survival.]     

cis-platinum,adriamycin, and hexamethylmelamine versus cyclophosphamide in advanced ovarian carcinoma

Fifty-three evaluable patients with disseminated ovarian carcinoma (FIGO III or IV) not treated with prior chemotherapy were randomized to receive either combination chemotherapy consisting of cis-platinum 40 mg/m2 IV on day 1, adriamycin 40 mg/m2 IV on day 1, and hexamethylmelamine 150 mg/m2 PO on days 2-10 up to a maximum of 200 mg on a 4-weekly cycle, or moderate-dose cyclophosphamide alone 40 mg/kg given IV intermittently every 3 weeks. Entry was from 1. 11. 1978 until 30. 4. 1981 (last follow-up 31. 10. 1981). Pretreatment characteristics in both groups of patients, regarding median age at diagnosis, median time from diagnosis to chemotherapy, FIGO stage, histology, differentiation grade, type of surgery, residual disease, previous radiotherapy, and median performance status, were comparable. Objective responses were seen in 18 of 27 (66%) of patients receiving cyclophosphamide alone (range 5--32+ months) and in 10 of 26 (38%) of patients treated with the combination (range 3--30+ months), this difference being statistically significant (chi 2 = 4.228; P less than 0.05). The median duration of objective response (11 vs 10 months) and the median survival (12 vs 11 months) were greater in the cyclophosphamide group, but these differences were not statistically significant. The toxicity of the combination was more severe. It is concluded that there is no therapeutic advantage for this combination schedule over the alkylating agent used alone.     

Integrating concurrent navelbine and cisplatin to hyperfractionated radiotherapy in locally advanced non-small cell lung cancer patients treated with induction and consolidation chemotherapy: feasibility and activity results

OBJECTIVES: The purpose of this study was to determine the effectiveness and toxicity of a new combination schedule based on concurrent navelbine, cisplatin and hyperfractionated radiotherapy in patients with locally advanced NSCLC treated with platinum and gemcitabine induction and consolidation chemotherapy. MATERIALS AND METHODS: The 37 patients with pathological confirmed advanced NSCLC (non-surgical stages IIIA and IIIB) were included in the study. All of them were assessable for survival and 32 for response. The treatment schedule consisted of cisplatin (100 mg/m2) or carboplatin (400 mg/m2) on day 1 with gemcitabine (1000 mg/m2) on days 1, 8 and 15. Treatment was given every 28 days for two courses, followed by concurrent administration of accelerated modified hyperfractionated radiotherapy, with concomitant boost, with a total dose of 61.64 Gy administered for 5 weeks, with cisplatin and navelbine, for two courses, finally followed by two courses of the same initial chemotherapy. RESULTS: Four patients achieved complete response (12.5%) and 14 (44%) partial response, for an overall objective response rate of 56.5%. After a minimum follow-up duration of 35.5 months, median progression free survival was 12.2 months. The median survival was 15.4 months with actuarial 1-, 2- and 3-year survival of 67, 21 and 15%, respectively. The main toxicity was hematological. There was esophagitis (grades III and IV) in 30% of the patients and there were two treatment-related deaths. CONCLUSION: Combined treatment with concurrent radiotherapy and chemotherapy in non-surgical NSCLC is an acceptable treatment modality. However, the toxicity was not negligible.     

Treatment of previously treated metastatic breast cancer by mitoxantrone and 48-hour continuous infusion of high-dose 5-FU and leucovorin (MFL): low palliative benefit and high treatment-related toxicity

For previously treated advanced breast cancer, there is no standard second-line therapy. Combination chemotherapy with mitoxantrone, high-dose 5-fluorouracil (5-FU) and leucovorin (MFL regimen) had been reported as an effective and well tolerated regimen. From October 1993 to November 1995, we treated 13 patients with previously chemotherapy-treated metastatic breast cancer by mitoxantrone, 12 mg/m2, on day 1 and continuous infusion of 5-FU, 3000 mg/m2, together with leucovorin, 300 mg/m2, for 48 h from day 1 to 2. Each course of chemotherapy was given every 4 weeks. Most of these patients had more than two metastatic sites, with lung metastasis predominant. Seven patients had been treated with anthracycline. Seven patients had previously received radiotherapy and seven had received hormone therapy. Median number of courses of MFL regimen given was six and the median cumulative dose of mitoxantrone was 68.35 mg/m2. One patient had complete response, seven had stable disease, none had partial response and five had progressive disease. The overall objective response rate was 7.6%. The median follow-up period was 14 months. Median survival was 16 months. Median progression-free survival was 5 months. A complete responder had relapse-free survival up to 17 months. Major toxicities were cardiotoxicity and leukopenia. Eight patients were dead in the last follow-up; two of them died of treatment-related toxicity. The MFL regimen achieves little palliative benefit and induces severe toxicity at a fairly high rate. Administration of this regimen to breast cancer patients who have been treated by chemotherapy and those with impaired heart function requires careful attention.      

Neoadjuvant chemotherapy and radiation for inoperable carcinoma of the maxillary antrum: a matched-control study

A matched-control study comparing standard radiotherapy versus neoadjuvant chemotherapy and radiation was undertaken to clarify the effects of neoadjuvant systemic chemotherapy for locally advanced squamous cell carcinoma of the maxillary antrum. Thirty-four patients with inoperable maxillary cancer were treated with neoadjuvant chemotherapy and radiotherapy (Group II). Before starting radiotherapy, all patients in Group II received two or three cycles of neoadjuvant chemotherapy consisting of cisplatin and a 5-day continuous infusion of 5-fluorouracil with or without intravenous injection of vinblastine. Radiation doses ranged from 66 Gy to 75 Gy (median, 70 Gy). The response rate, patterns of failure, toxicity, and survival for Group II were compared with those for 34 stage-matched patients treated with radiation alone (Group I). Despite a higher response rate to neoadjuvant chemotherapy, the recurrence rate and patterns of treatment failure were not influenced by the addition of neoadjuvant chemotherapy. In most cases, neoadjuvant chemotherapy did not interfere with subsequent radiotherapy, and radiation-induced late complications occurred equally in both treatment groups. After a median follow-up of 48 months, there was no significant difference in 5-year actuarial survival or disease-free survival between the two treatment groups. Radiation alone for inoperable maxillary cancer was clearly suboptimal for improving local control and survival rate, but neoadjuvant chemotherapy in addition to standard radiotherapy failed to demonstrate any therapeutic advantage over radiation alone.     

Two cycles of cisplatin-vindesine and radiotherapy for localized nonsmall cell carcinoma of the lung (stage III). Results of a prospective trial with 149 patients

One hundred forty-nine patients with localized nonsmall cell carcinoma of the lung (Stage III A and B) were treated with two monthly cycles of initial chemotherapy that included vindesine-cisplatin followed by 6000 cGy of thoracic irradiation. Patients with complete, partial, and minor response after initial chemotherapy were randomized into groups to receive either maintenance chemotherapy (four cycles) after radiotherapy or radiotherapy alone. The objective response rate was 24% after chemotherapy and 41% after combined chemoradiotherapy (complete response, 7.5%). The overall median survival was 9 months and the 2-year survival was 14%. Survival was identical with or without maintenance chemotherapy. The 2-year survival of patients with complete response was 75% compared with 9% for patients with partial or minor response. These results suggest that only the few patients (ten) who achieve complete response have a strong probability of survival. It is therefore essential to search for other therapeutic modalities that result in an increase of the complete response rate.     

诱导化疗与放化疗联合治疗合并同侧胸腔积液局限期小细胞肺癌的对比研究

Objective: The aim of the study was to explore the effects and side effects of induction chemotherapy followed by chemoradiotherapy for limited-disease small cell lung cancer (LD-SCLC) patients with ipsilateral pleural effusion.Methods: From January 2005 to May 2009, 52 LD-SCLC patients with ipsilateral pleural effusion were treated with induction chemotherapy got disappearance of pleural effusion after chemotherapy were underwent thoracic radiotherapy (TRT; 50 Gy/25 fraction) or same chemotherapy regimen; patients without disappearance or with increasing of pleural effusion after chemotherapy were given same chemotherapy regimen.Therapeutic effect was evaluated every two cycles according to RECIST 1.0 and side-effects were evaluated every cycle according to NCI-CTC AE Grades.All patients were followed up, and the median follow-up time was 26 months.Results: The response rate of patients was 80.7% (42/52) after induction chemotherapy and 34 patients got disappearance of pleural effusion.The median survival time, 1- and 2-year survival rates were 15.4 months, 76.9% (40 /52) and 38.5% (20 /52) respectively.The median survival time, 1- and 2-year survival rates of patients with pleural effusion remission received chest radiotherapy (A group, n = 20), patients with pleural effusion remission received chemotherapy (B group, n = 14) and patients without pleural effusion remission received chemotherapy (C group, n = 18) were 21.5 months, including myelosuppression, fatigue, nausea and vomiting.No therapeutic related death was occurred.Conclusion: Induction chemotherapy plus chemoradiotherapy has shown better effect in prolonging survival of small cell lung cancer (SCLC) patients with ipsilateral pleural effusion than chemotherapy alone.The patients with decreased ipsilateral pleural effusion may receive benefit from subsequent TRT.
