Preoperative Chemotherapy Alone and Combined with Preoperative Radiotherapy in Small-Size Breast Cancer

Abstract: Breast conservation surgery is an effective and safe treatment for many breast carcinomas. It may be possible to further limit the extent of resection (or expand the indication for breast conservation) by the application of preoperative chemotherapy and radiotherapy. We explored the feasibility of this in a pilot study.
Seventy-three patients (mean age 48, 63% premenopausal) with confirmed breast cancer, less than 2.5 cm, received chemotherapy (Group A) or chemotherapy plus radiotherapy (Group B) prior to limited resection (tumorectomy). Axillary dissection was always performed. Results: In 6/31 (19%) Group A and 17/42 (40%) Group B patients the tumor was not palpable after preoperative treatment, with complete pathological remission in 1 and 3 cases respectively. Histologic grading, mitosis, cellular alteration, and cellularity evaluations indicated a consistently greater therapeutic effect with chemoradiotherapy than with chemotherapy alone.
In conclusion, radiotherapy appears useful in the preoperative treatment of breast cancer and its use in association with various drug combinations should be further explored.     

A study to explore the role of a community oncology nurse specialist

Cancer patients are increasingly being cared for in the community. However, the role of the community oncology nurse specialist (CONS) remains a rare appointment in the United Kingdom. There is little research evidence to substantiate the view that this is a worthwhile and effective role. This study aimed to explore the role of one CONS using a qualitative case study approach. The sample consisted of the CONS, seven patients, no relatives and five community nurses. Semi-structured interviews were used to elicit the view of these participants. In addition, documents containing details of the CONS's work to date were reviewed. A number of the CONS's role components were identified by the different respondent groups. Five themes were identified within the data collected: functions of the CONS, communication between the CONS and other health care professionals, structural and organizational factors, characteristics of the service and benefits to patients and their families. Furthermore, all respondent groups were positive about the service offered by the CONS, and felt that the role was valuable. Some negative features were identified and these were concerned with organizational aspects of the service. The findings suggest the need for further research and evaluation in this area.     

Cisplatin-associated anaemia in patients with solid tumours

We have reviewed the incidence of cisplatin-induced anaemia in patients affected with solid tumours treated with at least three courses of first-line cisplatincontaining regimens. In our experience, a low percentage (5%) of patients required transfusions of red blood cells. We think it is of the utmost importance to adopt uniform criteria in monitoring and treatment of patients at risk of developing cisplatin anaemia and to identify subsets of patients to eventually treat with erythropoietin.     

Phase I/II trial of dipyridamole, 5-fluorouracil,leukovorin, and mitoxantrone in metastatic breast cancer

Summary Based upon the hypothesis that dipyridamole would potentiate the cytotoxicity of mitoxantrone and the combination of 5-fluorouracil (5-FU) and leukovorin, we performed a phase I/II trial of the combination of dipyridamole, 5-FU, leukovorin, and mitoxantrone in patients with metastatic breast cancer. The dose of dipyridamole was fixed at 175 mg/m² by mouth every 6 h (700 mg/m²/day), based upon a previous phase I trial of oral dipyridamole with 5-FU and leukovorin. Dipyridamole therapy began 24 h prior to the first dose of chemotherapy and continued until 24 h after the last dose of chemotherapy for each course of treatment. At the initial dose level, leukovorin 200 mg/m² was given intravenously immediately prior to 5-FU 375 mg/ m² intravenously on days 1–5. Mitoxantrone 6 mg/m² was given as a single dose on day 3. Unacceptable toxicity was observed at this dose level, leading to successive dose decrements rather than dose increments. The maximum tolerated dose was leukovorin 200 mg/m² days 1–2, 5-FU 375 mg/m² days 1–2, mitoxantrone 6 mg/m² on day 2, and dipyridamole 175 mg/m² every 6 h on days 0–3. Two responses were produced in 15 patients. This regimen is not recommended for further investigation in the treatment of breast cancer.     

药物敏感试验指导肺癌合并恶性胸腔积液的顺铂联合其他药物胸腔内化疗

目的用药物敏感试验预测肺癌合并恶性胸腔积液癌细胞对顺铂联合其他药物的敏感度，观察其在指导此类患者的顺铂联合其他化疗药物胸腔内化疗的价值。方法将44例胸腔积液癌细胞阳性肺癌患者随机分为两组：药物敏感试验组（20例，有2例因体外药物敏感试验失败而被排除）和对照组（22例）。药物敏感试验组患者用三磷酸腺苷-肿瘤细胞药物敏感试验（ATP-TCA）法分别检测胸腔积液癌细胞对顺铂加香菇多糖、顺铂加甘露聚糖肽、顺铂加A群链球菌制剂、顺铂加干扰素、顺铂加金黄色葡萄球菌滤液制剂、顺铂加卡介苗多糖核酸、顺铂加红色诺卡菌细胞壁骨架、顺铂加白细胞介素-2的敏感度，并选择抑瘤率最高的联合化疗药物对患者进行胸腔内化疗，观察治疗后胸腔积液完全缓解率及胸腔积液癌细胞转阴率，并与对照组比较。结果药物敏感试验组患者对各联合化疗药物敏感的例数为：顺铂加香菇多糖14例、顺铂加甘露聚糖肽18例、顺铂加A群链球菌制剂17例、顺铂加干扰素10例、顺铂加金黄色葡萄球菌滤液制剂16例、顺铂加卡介苗多糖核酸15例、顺铂加红色诺卡菌细胞壁骨架17例、顺铂加白细胞介素-216例。药物敏感试验组完全缓解率为65．0％，对照组为27．3％（P〈0．05）。药物敏感试验组胸腔积液癌细胞转阴率为80．0％，对照组为45．5％（P〈0．05）。结论用药物敏感试验指导肺癌合并恶性胸腔积液的胸腔内个体化化疗可提高完全缓解率和胸腔积液癌细胞转阴率，该方法具有临床实用价值。     

两种化疗方案治疗晚期非小细胞肺癌的对比观察

目的比较化疗方案GP(吉西他滨和顺铂)和IVP(异环磷酰胺、长春地辛和顺铂)治疗晚期非小细胞肺癌(NSCLC)的疗效和毒性.方法将62例晚期NSCLC患者随机分成两组,治疗组30例,采用GP方案:吉西他滨1000 mg/m^2第1、第8 d静脉滴注,顺铂80 mg/m^2第1 d静脉滴注,4周为一周期;对照组32例,采用IVP方案:异环磷酰胺1200 mg/m^2第1～第3 d静脉滴注,长春地辛2.5 mg/m^2第1、第8 d静脉推注,顺铂80 mg/m^2第1 d静脉滴注,4周为一周期.2个周期后评价其疗效及毒性.结果治疗组无一例完全缓解,部分缓解6例,总有效率20.0%;对照组亦无一例完全缓解,部分缓解8例,总有效率25.0%.两组无统计学差异(P＞0.05),但治疗组毒性小于对照组.结论双药化疗方案GP治疗NSCLC的疗效不低于三药方案IVP,且毒副作用轻微,更易为晚期肺癌患者所接受.
