[Chemoradiation for locally advanced non-small cell lung cancer].

Chemoradiation is one of the major therapeutic options in thoracic oncology: besides surgery, the best treatment for early-stage tumors, and chemotherapy, not only used in metastatic tumors, but also in a neoadjuvant and adjuvant setting, chemoradiation is the standard strategy for unresectable locally advanced non-small cell lung cancer. Its current modalities include three-dimensional conformal techniques, allowing dose escalation and sequential and concurrent combination with new generation cytotoxic agents to occur. Phase III trials are currently evaluating the benefit from induction and consolidation chemotherapy in this setting. New techniques of radiation may also increase the efficacy and the feasibility of radiation. This constant progress makes chemoradiation one of the most promising combined treatments in thoracic oncology.

[Therapeutic strategies in superior sulcus tumors: a model for combined modality therapy in non-small cell lung cancer].

Superior sulcus tumors have been individualized among other non-small cell lung cancers because of their characteristic clinical presentation in connection with their local extension to the chest wall and the brachial plexus. For a long time considered as marginally resectable, superior sulcus tumors have been treated since the early 1960's, with a combined approach including preoperative radiotherapy and curative-intent surgery. Surgical resection includes both thoracic, cervical and neurosurgical approach, and aims at obtaining complete resection, which has been identified as a determining prognostic factor in most reported series. Two recent phase II trials showed the benefit, both regarding resectability and local control rates, and survival of combined therapeutic strategies including induction platinum-based chemoradiation, extensive surgical resection, and adjuvant chemotherapy. Adjuvant radiotherapy is not recommended at the time, but needs to be re-evaluated regarding its recent technical optimisation. Similarly to other locally advanced non-small cell lung cancers, exclusive chemoradiation is the standard treatment of unresectable superior sulcus tumors. In this way, radiotherapy has shown to offer a prolonged analgesia in more than 75% of cases, and is associated with concurrent or sequential chemotherapy, with comparable results to those observed in stage III lung cancer. These developments make superior sulcus tumors a therapeutic model for locally advanced non-small cell lung cancer, whereby the benefit of combined multimodal strategies including induction chemoradiation and surgical resection are currently evaluated in phase III trials.

[Present and future of the image guided radiotherapy (IGRT) and its applications in lung cancer treatment].

These last years, the new irradiation techniques as the conformal 3D radiotherapy and the IMRT are strongly correlated with the technological developments in radiotherapy. The rigorous definition of the target volume and the organs at risk required by these irradiation techniques, imposed the development of various image guided patient positioning and target tracking techniques. The availability of these imaging systems inside the treatment room has lead to the exploration of performing real-time adaptive radiation therapy. In this paper we present the different image guided radiotherapy (IGRT) techniques and the adaptive radiotherapy (ART) approaches. IGRT developments are focused in the following areas: 1) biological imaging for better definition of tumor volume; 2) 4D imaging for modeling the intra-fraction organ motion; 3) on-board imaging system or imaging devices registered to the treatment machines for inter-fraction patient localization; and 4) treatment planning and delivery schemes incorporating the information derived from the new imaging techniques. As this paper is included in the "Cancer-Radiotherapie" special volume dedicated to the lung cancers, in the description of the different IGRT techniques we try to present the lung tumors applications when this is possible.

[Neoadjuvant chemoradiation in non-small cell lung cancer].

In 2006 preoperative chemoradiation is a major part of the treatment of stage III locally advanced non-small cell lung cancer. Previous studies have clearly demonstrated the feasibility both regarding toxicities and resectability rates of the sequential and concurrent combination of radiation to chemotherapy in a neoadjuvant setting. However, induction chemoradiation has never been randomly compared to exclusive preoperative chemotherapy. Besides, the doses of radiation and the optimal drug combination remain undetermined at the time. Regarding the global therapeutic strategy of stage III non-small cell lung cancer, recently reported phase III trials evaluating the role of surgical resection after induction chemotherapy or chemoradiation, all showed the prognostic importance of the tumoral and mediastinal downstaging to select patients really benefiting from surgery. These developments make of the treatment of locally advanced non-small cell lung cancer a model for multimodal therapeutic strategies combining chemotherapy, radiotherapy and surgery.

[Surgery and chemoradiation in stage IIIA non-small cell lung cancer].

Combination of surgery and radiotherapy has become a standard regimen in multiple cancers. Because of its toxicity and the higher metastatic potential of lung cancer, leading to underestimate the impact of loco-regional treatments, this strategy is currently used only in a clinical trial setting. Recent results from phase III studies comparing surgery and radiotherapy in stage IIIA-N2 locally advanced non-small cell lung cancer after induction treatment showed that surgery should only be performed in patients presenting with a major mediastinal downstaging and possible curative resection within a lobectomy. In all other cases, exclusive chemoradiation remains the therapeutic standard at the time. In this way, all patients with stage III non-small cell lung cancer may receive induction treatment, consisting either in chemotherapy or in sequential or concurrent chemoradiation, which has shown its feasibility and its efficacy regarding tumor response, resectability and local control rates. These two induction regimens are currently compared in randomized trials including stage III resectable and unresectable tumors at time of diagnosis. These developments make treatment of locally advanced non-small cell lung cancer a model for multimodal strategies in oncology, combining chemotherapy, radiotherapy and surgery.

Adjuvant gemcitabine and concurrent radiation for patients with resected pancreatic cancer: a phase II study.

The safety and efficacy of gemcitabine and concurrent radiation to the upper abdomen followed by weekly gemcitabine in patients with resected pancreatic cancer was determined. Patients with resected adenocarcinoma of the pancreas were treated with intravenous gemcitabine administered twice-weekly (40 mg m(-2)) for 5 weeks concurrent with upper abdominal radiation (50.4 Gy in 5(1/2) weeks). At the completion of the chemoradiation, patients without disease progression were given gemcitabine (1000 mg m(-2)) weekly for two cycles. Each cycle consisted of 3 weeks of treatment followed by 1 week without treatment. Forty-seven patients were entered, 46 of whom are included in this analysis. Characteristics: median age 61 years (range 35-79); 24 females (58%); 73% stage T3/T4; and 70% lymph node positive. Grade III/IV gastrointestinal or haematologic toxicities were infrequent. The median survival was 18.3 months, while the median time to disease recurrence was 10.3 months. Twenty-four percent of patients were alive at 3 years. Only six of 34 patients with progression experienced local regional relapse as a component of the first site of failure. These results confirm the feasibility of delivering adjuvant concurrent gemcitabine and radiation to the upper abdomen. This strategy produced good local regional tumour control.

Gemcitabine and radiation therapy in non-small cell lung cancer: state of the art.

Stage III non-small cell lung cancer (NSCLC) treatment is evolving. There are several choices available regarding which chemotherapy to use and how to optimally combine them with radiotherapy. Gemcitabine (Gemzar, Eli Lilly and Company, Indianapolis, USA) is a chemotherapeutic agent with activity in NSCLC, and preclinical studies have shown that gemcitabine is a potent radiosensitizer. These two characteristics make gemcitabine a potential option when treating patients with stage III NSCLC. This review article describes the efficacy and tolerance of gemcitabine when combined with radiation in those patients. Gemcitabine used concurrently with radiation, as an induction regimen before radiation, and as a consolidation regimen after radiation is reviewed.

[Tolerance and efficacy of conformal radiotherapy for hepatocellular carcinoma in cirrhotic patients. Results of the French RTF1 phase II trial].

PURPOSE: While some patients presenting with hepatocellular carcinoma (HCC) benefit from curative therapies (transplantation, surgery, percutaneous ablation), others are only candidates for palliative options such as chemoembolization or symptomatic care. Although conventional external-beam radiotherapy of the liver is regarded as little efficient and potentially toxic in cirrhotic patients, 3-dimensional conformal radiotherapy (CRT), by decreasing the amount of normal liver included in the radiation portal, allows dose escalation to occur without increasing the risk of radiation-induced hepatitis. This trial was designed to assess the efficacy and tolerance of CRT for small-size HCC in cirrhotic patients. PATIENTS AND METHODS: Prospective phase II trial including stage A/B cirrhotic patients with small-size HCC not suitable for curative treatments; CRT consisted in a standard fractionation radiation, with a total dose of 66 Gy. RESULTS: Twenty-seven patients were included, 15 of whom had previously been treated for HCC; mean age was 68. Among the 23 assessable patients, 18 (78%) presented with complete response, 3 (13%) with partial response, and 2 with no response. Acute complications occurred in 24 patients, and were mainly acceptable (grade 1/2: 22 patients, grade 3/4: 11 patients, 4 (15%) of whom had clinical and/or hematological toxicities). Only 2 (9%) grade 3/4 clinical and/or hematological late toxicities are reported. CONCLUSION: CRT is a non-invasive curative technique highly suitable for small-size HCC in cirrhotic patients; further investigations are needed to compare it to the other available treatments, and to integrate it into the curative therapeutic algorithm of HCC.

[Non-small cell bronchial carcinoma: optimisation of radiotherapy].

INTRODUCTION: Radiotherapy is involved in several ways in the treatment of non-small cell bronchial carcinoma (NSCBC). BACKGROUND: Three dimensional radiotherapy, with or without chemotherapy, is current practice, radiotherapy with respiratory gating and with intensity modulation are being evaluated Developments in imaging allow more precise definition of target volume, and stereotactic irradiation and proton therapy are little used at present but very promising. VIEWPOINT: The level of local control of NSCBC remains unsatisfactory. The results will certainly improve in association with advances in three areas: chemotherapy, better dose escalation and more precise targeting of tumour volume. CONCLUSION: Improvement in the management of NSCBC depends on these new treatment modalities that are still being evaluated and improved, with the aim of obtaining a longer survival and a better quality of life with reduced toxicity and side effects.

[Which treatments should be proposed in resectable stage III cancers?].

The results of surgery alone or associated with an adjuvant treatment, chemo- and/or radio-therapy, in the management of stage III resectable non-small cell lung cancer (NSCLC), are disappointing; with survival rates at 5 years generally lesser than 20% and many local and distant relapses. They justified the development of phase II trials that showed the feasibility of the chemotherapy and neo-adjuvant chemo-radiotherapy with high rates of response and acceptable toxicity. The three phase III studies with induction chemotherapy gave contradicting results; two of them were on small cohorts and presented methodological biases. Regarding pre-surgery chemo-radiotherapy, there is presently no published phase II trial and a recent phase II trial was in favour of a concomitant mode with bifractioned irradiation. The new targeted therapeutic agents do not yet have an indication in this field. In the particular case of resectable tumours of the apex invading the wall, so-called Pancoast, neo-adjuvant chemoradiotherapy followed by surgical resection has become the treatment of choice. The place of chemotherapy, radiotherapy and even surgery in the treatment of resectable stage III NSCLC remains to be defined and the inclusion of patients in randomised clinical trials is recommended.

[Chemoradiation for pancreatic adenocarcinoma].

Surgery remains the cornerstone treatment for pancreatic adenocarcinoma. However, 5% to 20% of tumors only are regarded as resectable, and, among them, only few benefit from an histological complete resection, major survival parameter. These data explain the overall poor prognosis of this disease, with a respectively 20% and 5% 1- and 5-year survival rates. These results justify an adjuvant or neoadjuvant therapeutic approach, mainly based on concurrent chemoradiation, with and without surgery. This paper reviews the different therapeutic approaches of non metastatic pancreatic adenocarcinoma.

Induction treatment before surgery for non-small cell lung cancer.

Surgery alone is currently still accepted "standard of care" for patients with operable NSCLC, this includes stages IA and IIB, as well as selected early subsets of IIIA disease. In more advanced and inoperable stage III disease, combinations of chemotherapy and radiotherapy remain the standard treatment approach for patients with good performance status. The role of surgery following induction therapy in these advanced stage III patients is at the moment not conclusively defined. More evidence from randomized trials is clearly needed to tailor treatment for the large number of patients that present in these locally advanced stages. Enrollment of patients into ongoing prospective clinical trials should be encouraged, whenever possible, to further define prognostic factors and improve multimodality strategies in this clinical setting.

[Randomised phase III trial of fotemustine versus fotemustine plus whole brain irradiation in cerebral metastases of melanoma].

PURPOSE: The main objective of this prospective multicenter randomised phase III study was to compare a combined regimen of fotemustine plus whole brain irradiation versus fotemustine alone in terms of cerebral response and time to cerebral progression in patients with melanoma brain metastases. PATIENTS AND METHODS: Seventy-six patients (instead of the 106 planned patients; study was stopped after the interim analysis) were randomised receiving either fotemustine (arm A, n = 39) or fotemustine and whole brain irradiation (arm B, n = 37). Fotemustine was administered intravenously at 100 mg m(-2) on day 1, 8 and 15, followed by a 5-week rest period, then every 3 weeks in non-progressive patients. In arm B, a concomitant whole brain irradiation was performed at the total dose of 37.5 Gy (2.5 Gy/d(-1), days 1-5, 3 consecutive weeks). RESULTS: Although patients who received fotemustine alone had worse prognostic factors, there was no significant difference in brain response (arm A: 7.4%, B: 10.0%) or control rates (objective response plus stable disease) after seven weeks (arm A: 30%, B: 47%) and overall survival (arm A: 86d, B: 105d). However, there was a significant difference in favour of arm B for the time to brain progression (p = 0.028, Wilcoxon test). CONCLUSION: Fotemustine plus whole brain irradiation delayed the time to brain progression of melanoma cerebral metastases compared to fotemustine alone but without a significant improvement in terms of objective control or overall survival.

[Chemoradiation in pancreatic carcinoma].

Prognosis of pancreatic carcinoma remains poor, with one-year and five-year overall survival rates of 20 and 5% respectively. Only 5 to 15% of patients present with tumors amenable to resection. Long-term (5 years) survival after curative resection is less than 20%, and the median survival is about 12 months. This paper updates recent trends about concomitant chemoradiation. At first, a review of the studies on adjuvant chemoradiation after surgery is proposed. Then, indications of preoperative chemoradiation for patients with localized resectable adenocarcinoma are discussed. The last part concerns the most important and recent studies about chemoradiation in locally advanced pancreatic cancer, either with 5-fluoro-uracile or based on new drugs like gemcitabine.

A prospective randomized multicentre phase III trial of fotemustine plus whole brain irradiation versus fotemustine alone in cerebral metastases of malignant melanoma.

The main objective of this prospective multicentre randomized phase III study was to compare a combined regimen of fotemustine plus whole brain irradiation with fotemustine alone in terms of cerebral response and time to cerebral progression in patients with melanoma cerebral metastases. Seventy-six patients were randomized to receive either fotemustine (arm A, n = 39) or fotemustine plus whole brain irradiation (arm B, n = 37). Fotemustine was administered intravenously at 100 mg/m(2) on days 1, 8 and 15, followed by a 5 week rest period, then every 3 weeks in non-progressive patients. In arm B, concomitant whole brain irradiation was performed at a total dose of 37.5 Gy (2.5 Gy/day on days 1-5 for three consecutive weeks). Although patients who received fotemustine alone had worse prognostic factors, there was no significant difference in cerebral response (arm A, 7.4%, arm B, 10.0%) or control rates (objective responses plus stable disease) after 7 weeks (arm A, 30%; arm B, 47%) or in overall survival (arm A, 86 days; arm B, 105 days). However, there was a significant difference in favour of arm B for the time to cerebral progression (P = 0.028, Wilcoxon test). In conclusion, fotemustine plus whole brain irradiation delayed the time to cerebral progression of melanoma cerebral metastases compared with fotemustine alone but without a significant improvement in terms of objective control or overall survival.
