Three Weekly Versus Weekly Cisplatin as Radiosensitizer in Head and Neck Cancer: a Decision Dilemma

Cisplatin-based concurrent chemoradiation plays an undisputed key role as definitive treatment in unresectable patients with locally advanced squamous cell carcinoma head and neck or as an organ preservation strategy. Treatment with 100 mg/m2 3-weekly cisplatin is considered the standard of care but is often associated with several adverse events. The optimum drug schedule of administration remains to be defined and presently, there is insufficient data limiting conclusions about the relative tolerability of one regimen over the other. This review addresses regarding the optimal dose schedule of cisplatin focusing mainly on three-weekly and weekly dose of cisplatin based concurrent chemoradiotherapy in locally advanced head and neck cancer with an emphasis on mucositis, dermatitis, systemic toxicity, compliance, and treatment interruptions. To derive a definitive conclusion, large prospective randomized trials are needed directly comparing standard 3-weekly cisplatin (100 mg/m2) with weekly schedule (30 - 40 mg/m2) of concurrent cisplatin based chemoradiotherapy in locally advanced squamous cell carcinoma head and neck.     

Weekly docetaxel with concomitant radiotherapy in patients with inoperable oesophageal cancer

Abstract Introduction: To evaluate the efficacy and tolerability of weekly docetaxel concurrent with radiotherapy in inoperable oesophageal cancer patients. Material and methods: Thirty-four oesophageal cancer patients with co-morbid medical conditions, locally advanced tumours (T4) or advanced age (older than 75 years) received docetaxel (20 mg/m² weekly) plus concurrent radiotherapy (2 Gy daily, to a total dose of 66 Gy). Twenty-two patients (64%) were stage III, 19 of whom had T4 tumours. Results: Twenty-seven patients (79%) completed the planned chemoradiotherapy treatment. Nine patients (26%) achieved a complete response and 8 (24%) achieved a partial response, for an overall response rate of 50%. Median survival was 6 months, and 1-year survival was 35%. Patients with T4 tumours had significantly shorter survival than other patients: 5 months for T4 tumours vs. 11 months for T1–3 (p=0.04). Grade 3–4 oesophagitis occurred in 6 patients (17%). There were two treatment-related deaths due to radiation pneumonitis. Conclusions: Docetaxel plus concurrent radiotherapy is active in poor-prognosis oesophageal cancer patients, with a lower incidence of severe oesophagitis than with cisplatin-based chemoradiotherapy regimens. This schedule can be considered, especially in patients with non-T4 tumours who are not candidates for oesophageal resection.     

局部晚期非小细胞肺癌调强放射治疗加同步化疗与序贯化疗疗效的对比分析

目的对比局部晚期非小细胞肺癌（10callyadvancednon—smallcelllungcancer,LANSCLC）采用调强放射治疗加铂类为基础的同步化疗或序贯化疗两种模式治疗患者的近期和远期疗效以及毒副反应,探索安全有效的治疗方法。方法对2005年11月至2012年3月收治的66例行同步放化疗或序贯放化疗的LANSCLC患者进行回顾性分析,对比两组患者的近期和远期疗效及毒副反应。结果同步放化疗与序贯放化疗组相比,在近期有效率（72．4％vs51．4％,P=0．08）、中位无进展生存时间（31．5个月vs10．2个月,P=0．043）、中位总生存时间（45．4个月vs18．9个月,P=0．028）方面,同步放化组均优于序贯放化组,且差异有统计学意义。另外,经多因素分析显示,是否采用同步放化疗模式为LANSCLC患者的独立预后因素。毒副反应方面,3级及以上放射性肺炎（10．3％vs5．4％,P=0．45）和放射性食管炎（27．6％vs16．2％,P=0．26）同步放化疗组有所增高,但差异无统计学意义,3级及以上血液学毒性（20．7％vs5．4％,P=0．05）同步放化疗组显著增高。结论对于一般状况良好的LANSCLC患者采用调强放射治疗加铂类为基础的同步化疗,可以提高患者的肿瘤客观缓解率,延长患者的无进展生存时间和总生存时间,且毒副反应可以耐受。     

Concurrent Weekly Cisplatin Versus Triweekly Cisplatin with Radiotherapy in the Treatment of Cervical Cancer: A Metaanalysis Result

Aims: To evaluate the adverse effect and survival outcome of weekly and triweekly cisplatin with radiotherapyin treatment of cervical cancer. Methods: After an extensive literature search between 1995-2011,we analyzed7 studies to compare weekly cisplatin and triweekly cisplatin combined radiotherapy. Results: Our analysisestablished that weekly cisplatin has a lower risk of hematologic toxicity than triweekly cisplatin with concurrentradiotherapy in the treatment of cervical cancer. However, there were no differences in progression free survivaland overall survival between weekly cisplatin and triweekly cisplatin (p>0.05). Conclusions: Weekly cisplatincombined with concurrent radiation has lower risk in hematologic toxicity than triweekly cisplatin, but does notimprove survival. Triweekly cisplatin treatment has longer intervals and is therefore more convenient. Cliniciansand patients can choose either weekly cisplatin or triweekly cisplatin combined radiotherapy for cervical cancer.

Response to combined modality therapy correlates with survival in locally advanced non-small-cell lung cancer

PURPOSE: Although concurrent chemoradiotherapy can now achieve demonstrated long-term survival in patients with locally advanced non-small-cell lung cancer (LANSCLC), it is difficult to predict which patients will benefit most from this therapeutic approach. Studies have suggested that local control, and the response to therapy, may be linked to improved survival; however, detailed analysis of the impact of tumor response to chemoradiotherapy on survival has not been thoroughly reported. Therefore, we sought to determine the impact of the response rate on survival for patients who were treated with combined modality therapy for LANSCLC. METHODS AND MATERIALS: We reviewed the data from 116 patients enrolled between 1994 and 1997 in three trials investigating paclitaxel-based concurrent chemoradiotherapy for LANSCLC. Tumor size measurements were assessed immediately before and 2 months after completion of combined modality therapy to determine the response and to calculate the percentage of decrease in tumor size. RESULTS: Patients with a response (complete or partial) had an improved 4-year overall survival rate compared with patients with no response (stable or progressive disease; 21.1% vs. 3.3%, p <0.0001) in the 109 assessable patients. Progression-free survival also improved significantly with response. An analysis of the percentage of decrease in tumor size vs. survival was performed (n = 74) using Cox proportion model analysis. After combined modality therapy, a 20%, 40%, 60%, 80%, and 100% decrease in tumor size conferred a 39%, 63%, 78%, 86%, and 92% reduction in risk of death compared with a 0% decrease in tumor size (p <0.0001). CONCLUSION: The response by conventional response criteria correlated strongly with improved overall survival and progression-free survival and an increasing percentage of decrease in tumor size resulted in a reduction in the risk of death. Additional investigation of the degree of response as a factor predictive of improved therapeutic efficacy, translating into improved survival, is warranted.
