Neo-adjuvant chemotherapy followed by either continuous hyper-fractionated accelerated radiation therapy week-end less or conventional chemo-radiotherapy in locally advanced NSCLC-A randomised prospective single institute study

Context: Better locoregional control and increased overall survival by continuous hyper fractionated accelerated radiotherapy have been shown in unresectable nonsmall cell lung carcinoma (NSCLC). Dose escalation and neoadjuvant chemotherapy (NACT) along with continuous hyperfractionated accelerated radiotherapy week end-less (CHARTWEL) were also tried for improved survival. In this present study, we compared the results of NACT followed by CHARTWEL against NACT followed by conventional concurrent chemo-radiation therapy. Aims: The aim of this study is to compare the locoregional control and toxicities in NSCLC Stage IIIA and B in both arms. Settings and Design: Randomized, prospective single-institutional study with a study population comprising all locally advanced unresectable NSCLC patients enrolled in 2014 at our institute. Subjects and Methods: All enrolled patients were randomized into two arms-CHARTWEL and concomitant chemo-radiotherapy (CCRT), after three weeks of the fourth cycle of NACT. In CHARTWEL arm 30 patients received two-dimensional radiotherapy (RT) 58.5 Gy/39 fr/2.5 weeks while in CCRT arm 30 received 66 Gy/33 fr/6.5 weeks. Disease response was evaluated at 6 months and toxicity assessment during and after treatment completion. Data were analyzed using tools such as percentage, mean, Chi-square test and P value. Chi-square and P value was calculated by statistical online software (http://quantpsy.org). Results: 28% of patients in study arm and 20% in control arm had complete response at 6 months after RT. Locoregional disease control was observed in 44% in study arm and 32% in control arm of patients. There was no statistical difference in grades of toxicities or overall survival (OS)/disease-free survival except persistent esophagitis Grade III seen in two patients of study arm. Conclusions: Study suggests that CHARTWEL in combination with NACT is an effective strategy to treat patients with locally advanced lung cancer with the advantage of a smaller dose and shorter duration. Although large multivariate studies still needed

The Clinico-Oncologic Outcomes of Elderly Patients with Glioblastoma after Surgical Resection Followed by Concomitant Chemo-Radiotherapy

BACKGROUND: There have been controversies in the treatment of elderly patients with glioblastoma. We introduce the outcome of the treatment of elderly patients with glioblastoma comparing with younger patients. METHODS: The author's hospital database was used to identify patients with histologically confirmed glioblastoma after surgery between January 2006 and December 2013. Forty-eight patients (control group) were under age 65 and 16 patients (elderly group) were aged 65 years or over at the time of surgery. RESULTS: The median age of the elderly group was 71 years and control group was 50 years. Mean number of medical comorbidities was 1.8 in the elderly group vs. 0.5 in the control group. The median progression free survival (PFS) was 5.6 months and the median overall survival (OS) was 19.9 months in all patients. The elderly group had a median PFS of 4.2 months vs. 8 months for the control group (log-rank test, p=0.762). Median OS was 8.2 months in the elderly group vs. 20.9 months in the control group (log-rank test, p=0.457). Major complications occurred in 5 cases (7.8%) for all patients. The ratio of completion of concomitant chemo-radiotherapy (CCRT) was 81.3% and was the same between the two groups. In multivariable analysis, extent of resection (p=0.034) and completion of CCRT (p=0.023) were statistically significant, independent prognostic factors only for PFS in all patients by Cox proportional hazards model. Age was not an independent prognostic factor. As for OS, there was no significant factor. CONCLUSION: Surgical resection and CCRT were well tolerated in elderly patients with glioblastoma, and maximal safe resection followed by timely CCRT could improve clinic-oncologic outcomes.

Research progress of nedaplatin in the treatment of nasopharyngeal carcinoma / 国际肿瘤学杂志

Inductive chemotherapy and concurrent chemoradiotherapy have been a focus on the clinical research in the treatment of nasopharyngeal carcinoma.Cisplatin,as a kind of representative platinum drug,can improve the curative effect,but it also brings a lot of side effects to nasopharyngeal carcinoma patients.The new kind of platinum drug-nedaplatin,can not only guarantee the curative effect but also reduce the side effects of chemotherapy.

Phase II study of concurrent cisplatinum with ifosfamide and radiotherapy in locally advanced squamous cell cervical carcinoma.

Objective: To evaluate the efficacy and toxicities of cisplatinum and ifosfamide administered concomitantly with radiation therapy in the treatment of locally advanced squamous cell cervical carcinoma (LASCC). Methods: Twenty patients with biopsy-proven squamous cervical carcinoma, FIGO stage II A to III B were entered into this study. All patients received standard radiotherapy (50 Gy in 25 fractions and brachytherapy at a dose of 268-28 Gy). Cisplatinum 70 mg/m2 plus ifosfamide 3 gm/m2 were administered totally for three cycles on Day 1, 21 and 42, concomitant with the radiotherapy schedule. Response and toxicities of treatment were evaluated and long term follow up was performed for disease free survival. Results: All patients received a course of concomitant chemoradiotherapy. Sixteen patients (80%) were able to receive a full course of chemotherapy, the remaining received 1-2 courses because of severe toxicities. The clinical complete response rate was 90% and overall 4 years survival rate was 85%. Grade 3 and 4 leucopenia occurred in 2 cases with one febrile neutropenia. Late complication revealed 2 cases of grade 3 cystitis. Conclusion: This study showed that concomitant chemoradiotherapy with cisplatinum plus ifosfamide was feasible for patients with LASCC. Further study of this regimen should be compared in randomized control trial (RCT) with cisplatinum alone and in the other histologic type of cervical cancer such as adenocarcinoma.

The Outcomes of Concomitant Chemoradiotherapy Followed by Adjuvant Chemotherapy with Temozolomide for Newly Diagnosed High Grade Gliomas : The Preliminary Results of Single Center Prospective Study

OBJECTIVE: Malignant gliomas are the most common primary cerebral neoplasms in adults. Despite multimodality treatments, the prognosis for patients with malignant glioma remains poor. However, recently, the effectiveness of concomitant chemoradiotherapy (CCRT) with temozolomide (TMZ) has been reported. We report for the first time preliminary results of the treatment with CCRT of newly diagnosed malignant gliomas in Korean people. METHODS: Thirty-two patients over the age of 17 years with newly diagnosed and histologically confirmed high-grade gliomas (HGG), from June 2004 to August 2007 were the subjects of this study. There were 17 men and 15 women, with a median age of 53.5 years (range, 17-74). Pathologically, glioblastoma, anaplastic astrocytoma, anaplastic oligodendroglioma, and gliomatosis cerebri had been diagnosed in eighteen, eight, four, and two patients, respectively. These 32 patients were treated with CCRT with TMZ. RESULTS: The median follow-up period was 12.5 months (range 3-48). At the time of this analysis, 13 patients died and three patients had been lost to follow-up. There was no mortality caused by drug toxicity. The median progression-free survival (PFS) of these patients was 9.0 months, and the six-month PFS rate was 72.4%. The median overall survival (OS) was 26 months, and the one-year OS rate was 83.6%. The 18 patients with glioblastoma were analyzed separately from the other patients with HGG, and the median OS was 18 months, and the one-year OS rates were 81.8%. The median PFS was seven months, and the six-month PFS rate was 75.0%. CONCLUSION: Our results are consistent with many other reports, confirming that CCRT with TMZ achieves good clinical outcomes in the treatment of HGG. Therefore, we suggest that CCRT with TMZ as adjuvant chemotherapy be considered as a standard therapy for patients with HGG.
