RESUMO

In recent years, the development of both medical imaging and new systemic agents (targeted therapy and immunotherapy) have revolutionized the field of oncology, leading to a new entity: oligometastatic disease. Adding local treatment of oligometastases to systemic treatment could lead to prolonged survival with no significant impact on quality of life. Given the high prevalence of lung oligometastases and the new systemic agents coming with increased pulmonary toxicity, this article provides a comprehensive review of the current state-of-art for radiotherapy of lung oligometastases. After reviewing pretreatment workup, the authors define several radiotherapy regimen based on the localization and size of the oligometastases. A comment on the synergistic combination of medical treatment and radiotherapy is also made, projecting on future steps in this specific clinical setting.

RESUMO

Metastatic lung cancer classically portends a poor prognosis. The management of metastatic lung cancer has dramatically changed with the emergence of immune checkpoint inhibitors, targeted therapy and due to a better understanding of the oligometastatic process. In metastatic lung cancers, radiation therapy which was only used with palliative intent for decades, represents today a promising way to treat primary and oligometastatic sites with a curative intent. Herein we present through a literature review the role of radiotherapy in the management of synchronous metastatic lung cancers.

RESUMO

Radiation-induced acute and late toxicity depends on several parameters. The type, severity and duration of morbidity are mainly related to irradiated volume, total dose and its fractionation and the intrinsic radiosensitivity of the patients. The follow-up of these toxicities is essential. However, unlike many specialties, morbidity and mortality reviews procedures are not developed as part of quality governance programs in radiation therapy departments for the monitoring of toxicity which sometimes hinder the patients' quality of life. One French survey published within the framework of the project entitled Prospective Registration of Morbidity and Mortality, Individual Radiosensitivity and Radiation Technique (Proust), conclude that there was a lack of knowledge of morbidity and mortality reviews and considerable confusion between these reviews and other quality processes without perspective for the local morbidity and mortality reviews development in a large number of the participated centers. In this article, we will discuss the procedure of the "ideal morbidity and mortality reviews" and its implementation through a monocentric experience started in 2015. Thus, the Proust project is a unique opportunity to implement and standardize a national morbidity and mortality reviews implementation in radiation therapy departments by involving the French regions.

RESUMO

PURPOSE: Roughly 20% of patients with non-small-cell lung cancer exhibit locally advanced, unresectable, stage III disease. Concurrent platinum-based chemoradiotherapy is the backbone treatment, which is followed by maintenance immunotherapy, yet with poor long-term prognosis. This phase II trial (IFCT-0803) sought to evaluate whether adding cetuximab to cisplatin and pemetrexed chemoradiotherapy would improve its efficacy in these patients. MATERIALS AND METHODS: Eligible patients received weekly cetuximab (loading dose 400mg/m2 day 1; subsequent weekly 250mg/m2 doses until two weeks postradiotherapy). Chemotherapy comprised cisplatin (75mg/m2) and pemetrexed (500mg/m2), both delivered on day 1 of a 21-day cycle of maximally four. Irradiation with maximally 66Gy started on day 22. Disease control rate at week 16 was the primary endpoint. RESULTS: One hundred and six patients were included (99 eligible patients). Compliance exceeded 95% for day 1 of chemotherapy cycles 1 to 4, with 76% patients receiving the 12 planned cetuximab doses. Maximal grade 3 toxicity occurred in 63% patients, and maximal grade 4 in 9.6%. The primary endpoint involving the first 95 eligible patients comprised two (2.1%) complete responses, 57 (60.0%) partial responses, and 27 (28.4%) stable diseases. This 90.5% disease control rate (95% confidence interval [95% CI]: 84.6%-96.4%) was achieved at week 16. After median 63.0-month follow-up, one-year and two-year survival rates were 75.8% and 59.5%. Median overall survival was 35.8months (95% CI: 23.5-NR), and median progression-free survival 14.4months (95% CI: 11.2-18.8), with one-year and two-year progression-free survival rates of 57.6% and 34.3%. CONCLUSION: These survival rates compare favourably with published data, thus justifying further development of cetuximab-based induction chemoradiotherapy.

RESUMO

INTRODUCTION: Lung cancer is the leading cause of cancer-related death. Delays may have an impact on patient survival. The objective of this study was to evaluate the diagnostic and therapeutic management times for patients admitted for lung cancer treatment in the Respiratory Department of CHU de Caen Normandie. MATERIALS AND METHODS: This is a retrospective, single-center and observational study, conducted on all patients treated for lung cancer from June 2017 to January 2018 in our department of pneumology in the Caen Normandie CHU. The main median times were investigated were: Global Time (abnormal imaging-treatment), Diagnosis time (abnormal imaging-diagnosis) and Treatment Time (diagnosis-treatment). RESULTS: One hundred and twenty-seven (127) patients were included. Median global time was 55.5 days [31,25; 393], median diagnosis time was 22 days [13; 49], and median treatment time was 24.5 days [12,25; 45]. DISCUSSION: Our treatment times are consistent with those previously published. Areas for improvement are being developed in accordance with the 2014-2019 cancer plan, in particularly the creation in our institution of a specific care pathway for patients with lung cancer.

RESUMO

Stereotactic radiotherapy is a fundamental change from the conventional fractionated radiotherapy and represents a new therapeutic indication. Stereotactic radiotherapy is now a standard of care for inoperable patients or patients who refuse surgery. The results are encouraging with local control and survival rates very high in selected populations. The rate of late toxicity remains acceptable. Good tolerability makes it appropriate even for elderly and frail patients. In these fragile patients or in certain specific clinical situations, different surgical, radiotherapy or interventional radiology attitudes can be discussed on a case-by-case basis. These situations are considered in this article for the pulmonary, hepatic and prostatic localizations.

RESUMO

Sarcomas are rare tumours arising from mesenchymal tissue. A multimodal management in an expert centre combining surgery and radiotherapy is the current standard of care for localized soft-tissue sarcomas of the extremities, to enable limb-sparing strategies. The delivery of pre- radiotherapy or postoperative radiotherapy offers similar local control and survival rates but the toxicity profile is quite different: preoperative radiotherapy increases the risk of wound complications and postoperative radiotherapy affects long-term functional outcomes. While postoperative radiotherapy has long been the rule, especially in Europe, technical improvements with image-guided- and intensity-modulated radiotherapy associated with a better management of postoperative wounds has tended to change practices with more frequent preoperative radiotherapy. More recently the possibilities of a hypofractionated regimen or potentiation by nanoparticles to increase the therapeutic index plead in favour of a preoperative delivery of radiotherapy. The aim of this paper is to report pros and cons of pre- and post-operative radiotherapy for soft-tissue sarcomas.

RESUMO

Anatomical changes and tumor regression during thoracic radiotherapy may alter the treatment volumes. These modifications are not taken into account into set-up or motion margins used for treatment planning. Their dosimetric impact could be significant and a better understanding of the changes occurring during the 6 to 7 weeks of treatment could be useful in order to define quantitative thresholds before a new treatment planning is needed. Margins could also be reduced in order to better spare organs at risk and perform targeted dose escalation. This review assesses the potential of morphologic and metabolic imaging during treatment for adaptive radiotherapy in non-small cell lung cancer.

RESUMO

BACKGROUND: We recently published the results of the PCI99 randomised trial comparing the effect of a prophylactic cranial irradiation (PCI) at 25 or 36 Gy on the incidence of brain metastases (BM) in 720 patients with limited small-cell lung cancer (SCLC). As concerns about neurotoxicity were a major issue surrounding PCI, we report here midterm and long-term repeated evaluation of neurocognitive functions and quality of life (QoL). PATIENTS AND METHODS: At predetermined intervals, the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and brain module were used for self-reported patient data, whereas the EORTC-Radiation Therapy Oncology Group Late Effects Normal Tissue-Subjective, Objective, Management, Analytic scale was used for clinicians' assessment. For each scale, the unfavourable status was analysed with a logistic model including age, grade at baseline, time and PCI dose. RESULTS: Over the 3 years studied, there was no significant difference between the two groups in any of the 17 selected items assessing QoL and neurological and cognitive functions. We observed in both groups a mild deterioration across time of communication deficit, weakness of legs, intellectual deficit and memory (all P < 0.005). CONCLUSION: Patients should be informed of these potential adverse effects, as well as the benefit of PCI on survival and BM. PCI with a total dose of 25 Gy remains the standard of care in limited-stage SCLC.

RESUMO

UNLABELLED: To report a retrospective study concerning the impact of fused 18F-fluorodeoxy-D-glucose (FDG)-hybrid positron emission tomography (PET) and computed tomography (CT) images on three-dimensional conformal radiation therapy (3D-CRT) planning for patients with non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: One hundred and one patients consecutively treated for stages I-III NSCLC were studied. Each patient underwent CT and FDG-hybrid PET for simulation treatment in the same radiation treatment position. Images were coregistered using five fiducial markers. Target volume delineation was initially performed on the CT images and the corresponding FDG-PET data were subsequently used as an overlay to the CT data to define target volume. RESULTS: FDG-PET identified previously undetected distant metastatic disease in 8 patients making them ineligible for curative CRT (one patient presented some positive uptakes corresponding to concomitant pulmonary tuberculosis). Another patient was ineligible for curative treatment because fused CT/PET images demonstrated excessively extensive intrathoracic disease. The gross tumor volume (GTV) was decreased by CT/PET image fusion in 21 patients (23%) and was increased in 24 patients (26%). The GTV reduction was > or = 25% in 7 patients because CT/PET image fusion reduced pulmonary GTV in 6 patients (3 patients with atelectasis) and mediastinal nodal GTV in 1 patient. The GTV increase was > or = 25% in 14 patients due to an increase of the pulmonary GTV in 11 patients (4 patients with atelectasis) and detection of occult mediastinal lymph node involvement in 3 patients. Among 81 patients receiving a total dose > or = 60 Gy at ICRU point, after CT/PET image fusion, the percentage of total lung volume receiving more than 20 Gy (VL20) increased in 15 cases and decreased in 22 cases. The percentage of total heart volume receiving more than 36 Gy increased in 8 patients and decreased in 14 patients. The spinal cord volume receiving at least 45 Gy (2 patients) decreased. After multivariate analysis, one single independent factor made significant effect of FDG/PET on the modification of the size of the GTV: tumor with atelectasis (P = 0.0001). Conclusion. - Our study confirms that integrated hybrid PET/CT in the treatment position and coregistered images have an impact on treatment planning and management of patients with NSCLC. FDG images using dedicated PET scanners with modern image fusion techniques and respiration-gated acquisition protocols could improve CT/PET image coregistration. However, prospective studies with histological correlation are necessary and the impact on treatment outcome remains to be demonstrated.

RESUMO

PURPOSE: To study the impact of fused (18)F-fluoro-deoxy-D-glucose (FDG)-hybrid positron emission tomography (PET) and computed tomography (CT) images on conformal radiation therapy (CRT) planning for patients with esophageal carcinoma. PATIENTS AND METHODS: Thirty-four patients with esophageal carcinoma were referred for concomitant radiotherapy and chemotherapy with radical intent. Each patient underwent CT and FDG-hybrid PET for simulation treatment in the same radiation treatment position. PET-images were coregistered using five fiducial markers. Target delineation was initially performed on CT images and the corresponding PET data were subsequently used as an overlay to CT data to define the target volume. RESULTS: FDG-PET identified previously undetected distant metastatic disease in 2 patients, making them ineligible for curative CRT. The Gross Tumor Volume (GTV) was decreased by CT and FDG image fusion in 12 patients (35%) and was increased in 7 patients (20.5%). The GTV reduction was >or=25% in 4 patients due to reduction of the length of the esophageal tumor. The GTV increase was >or=25% with FDG-PET in 2 patients due to the detection of occult mediastinal lymph node involvement in one patient and an increased length of the esophageal tumor in the other patient. Modifications of the GTV affected the planning treatment volume (PTV) in 18 patients. Modifications of delineation of GTV and displacement of the isocenter of PTV by FDG-PET also affected the percentage of total lung volume receiving more than 20 Gy (VL20) in 25 patients (74%), with a dose reduction in 12 patients and a dose increase in 13 patients. CONCLUSION: In our study, CT and FDG-PET image fusion appeared to have an impact on treatment planning and management of patients with esophageal carcinoma related to modifications of GTV. The impact on treatment outcome remains to be demonstrated.

RESUMO

PURPOSE: To evaluate our updated data concerning survival and locoregional control in a study of locally advanced non inflammatory breast cancer after primary chemotherapy followed by external preoperative irradiation. PATIENTS AND METHODS: Between 1982 and 1998, 120 patients (75 stage IIIA, 41 stage IIIB, and 4 stage IIIC according to AJCC staging system 2002) were consecutively treated by four courses of induction chemotherapy with anthracycline-containing combinations followed by preoperative irradiation (45 Gy to the breast and nodal areas) and a fifth course of chemotherapy. Three different locoregional approaches were proposed, depending on tumour characteristics and tumour response. After completion of local therapy, all patients received a sixth course of chemotherapy and a maintenance adjuvant chemotherapy regimen without anthracycline. The median follow-up from the beginning of treatment was 140 months. RESULTS: Mastectomy and axillary dissection were performed in 49 patients (with residual tumour larger than 3 cm in diameter or located behind the nipple or with bifocal tumour), and conservative treatment in 71 patients (39 achieved clinical complete response or partial response >90% and received additional radiation boost to initial tumour bed; 32 had residual mass or=6 cm in diameter, p =0.002). Ten-year overall metastatic disease-free survival rate was 61%. After multivariate analysis, metastatic disease-free survival rates were significantly influenced by clinical stage (stage IIIA-B vs. IIIC, p =0.0003), N-stage (N0 vs. N1-2a, and 3c, p =0.017), initial tumour size (<6 vs. >or=6 cm in diameter, p =0.008), and tumour response after induction chemotherapy and preoperative irradiation (clinically complete response + partial response vs. non-response, p =0.0015). In the non conservative breast treatment group, of the 32 patients with no change in clinical tumour size after induction chemotherapy, the 10-year metastatic disease-free survival rate was 59% with only one local relapse. Arm lymphedema was noted in 17% (14 of 81) following axillary dissection and in 2.5% (1 of 39) without axillary dissection. Cosmetic results were satisfactory in 70% of patients treated by irradiation alone and in 51.5% of patients after wide excision and irradiation. CONCLUSION: Despite the poor prognosis of patients with locally advanced non inflammatory breast cancer resistant to primary anthracycline-based regimen, aggressive locoregional management using preoperative irradiation and mastectomy with axillary dissection offers a possibility of long term survival with low local failure rate for patients without extensive nodal disease. On the other hand, the rate of local failure seems to be high in patients with clinical partial tumour response following induction chemotherapy and breast-conserving treatment combining preoperative irradiation and large wide excision.

RESUMO

PURPOSE: To evaluate preliminary results in terms of toxicity, local tumour control, and survival after preoperative concomitant chemoradiation for operable bulky cervical carcinomas. PATIENTS AND METHODS: Between December 1991 and October 2001, 42 patients (pts) with bulky cervical carcinomas stage IB2 (11 pts), IIA (15 pts), and IIB (16 pts) with 1/3 proximal parametrial invasion. Median age was 45 years (range: 24-75 years) and clinical median cervical tumour size was 5 cm (range: 4.1-8 cm). A clinical pelvic lymph node involvement has been observed in 10 pts. All patients underwent preoperative external beam pelvic radiation therapy (EBPRT) and concomitant chemotherapy during the first and the fourth radiation weeks combining 5-fluorouracil and cisplatin. The pelvic dose was 40.50 Gy over 4.5 weeks. EBPRT was followed by low-dose-rate uterovaginal brachytherapy with a total dose of 20 Gy in 17 pts. After a rest period of 5-6 weeks, all pts underwent class II modified radical hysterectomy with bilateral lymphadenectomy. Para-aortic lymphadenectomy was performed in eight pts without pathologic para-aortic lymph node involvement. Twenty-one of 25 pts who had not received preoperative uterovaginal brachytherapy underwent postoperative low-dose-rate vaginal brachytherapy of 20 Gy. The median follow-up was 31 months (range: 3-123 months). RESULTS: Pathologic residual tumour or lymph node involvement was observed in 23 pts. Among the 22 pts with pathologic residual cervical tumour (<0.5 cm: nine pts; >or=0.5 to 1 cm: 10 pts), seven underwent preoperative EBRT followed by uterovaginal brachytherapy vs. 15 treated with preoperative EBRT alone (P = 0.23). Four pts had pathologic lymph node involvement, three pts had vaginal residual tumour, and four pts had pathologic parametrial invasion. The 2- and 5-year overall survival rates were 85% and 74%, respectively. The 2- and 5-year disease-free survival (DFS) rates were 80% and 71%, respectively. After multivariate analysis, the pathologic residual cervical tumour size was the single independent factor decreasing the probability of DFS (P = 0.0054). The 5-year local control rate and metastatic failure rate were 90% and 83.5%, respectively. Haematological effects were moderate. However, six pts had grade 3 acute intestinal toxicity. Four severe late complications requiring surgical intervention were observed (one small bowel complication, three ureteral complications). CONCLUSION: Primary concomitant chemoradiation followed surgery for bulky operable stage I-II cervical carcinomas can be employed with acceptable toxicity. However, systematic preoperative uterovaginal brachytherapy should increase local tumour control.

RESUMO

PURPOSE: - To identify predicting factors of local control and survival after isolate local failure by statistical analysis of the data after breast-conserving treatment for early breast cancer. METHODS AND PATIENTS: - In time of local failure, mean age was 54.7 years old, mean tumor size was 19.3 mm and recurrence was more often infiltrating ductal carcinoma (88%). Local recurrence was unifocal in 44 cases and localised outside of the site of the primary tumorectomy in 35 cases. Local failure treatment was a radical mastectomy or parietectomy (53 patients). Hormonotherapy was delivered in 36 patients and chemotherapy was delivered in 26 patients. Mean follow-up was 62 months. RESULTS: - Fifteen patients developed second local recurrence in a mean time of 36 months. Five years local control rate was 68% after the first local failure. Surgery treatment (non-conservative surgery vs. conservative surgery) was the only factor which influenced local control. Six patients developed homolateral axillary and/or supraclavicular node recurrence. Twelve patients underwent metastasis in a mean time of 36 months after the first local recurrence. Five years metastasis free survival rate was 80%. Peritumoral vascular invasion in time of the first local failure increased metastasis risk and node recurrence. Second local failure did not alter metastasis free survival. CONCLUSION: - Peritumoral vascular invasion in time of the first local failure decreased node and metastasis free survival. Surgery should be radical, but the place of chemotherapy and hormonotherapy was not definite.

RESUMO

The coregistration of planning CT and 18F-fluoro-deoxy-2-glucose (FDG) positron emission tomography (PET) with patient in the same treatment position is the principally well-established tool for improving the target coverage defined and the target planning volume to treat the metabolic target volume. Most of the interest in the coresgistred CT/PET images on volume delineation has focused on conformal radiation therapy of non-small cell lung cancer. In spite of technical difficulties related to the target volume displacements, and the sensitivity and the specificity of FDG-PET images < 100%, the target volume delineation is significantly changed by the coregistration of FDG-PET images and planning CT by either reduction of the radiation volume (excluding atelectasis or mediastinal lymph node) or the increasing of mediastinal lymph node involvement. Image fusion technique reduces the interobserver variability in target volume delineation. Furthermore, after induction chemotherapy image fusion leads to improve the patient management by detecting locoregional progression disease or the presence of metastatic disease. Other anatomic tumor sites are going to investigate such as: head-and-neck cancer, gynecologic cancer, oesophageal cancer, anal cancer, Hodgkin's disease, and non-Hodgkin's lymphoma. The impact on treatment outcome remains to be demonstrated.

RESUMO

Since 1980, curative-intent radiation therapy of epidermoid carcinoma of the anal canal is the standard first line treatment. The combined concomitant chemotherapy and radiation therapy is presently established for locally advanced tumors more than 4 cm in length and/or with nodal involvement. We report the Tenon hospital experience since 1972 concerning the long term results after radiation therapy, the modifications of the radiation technique, and the evolution of treatment strategy.

RESUMO

The efficacy and toxicity of combined paclitaxel and gemcitabine was evaluated in 54 chemotherapy-naive patients with metastatic non-small cell lung cancer (NSCLC). Gemcitabine i.v. 1000 mg/m(2)was administered on days 1 and 8 and paclitaxel 200 mg/m(2)as a continuous 3-hour infusion on day 1. Treatment was repeated every 21 days. Patients had a median age of 53 years. ECOG performance status was 0 or 1 in 48 patients. 41 patients (75.9%) had initial stage IV disease; histology was mainly adenocarcinoma (46.3%). 2 patients (4.3%) achieved a complete response and 15 (31.9%) achieved a partial response giving an overall response rate of 36.2% (95% CI: 22.4-49.9%); 19 patients (40.4%) had stable disease and 10 (21.3%) had progressive disease. The median survival time was 51 weeks (95% CI: 46.5-59.3), with a 1-year survival probability of 0.48 (95% CI: 0.34-0.63). Grade 3/4 neutropenia and febrile neutropenia occurred in 15.2% and 2.2% of courses, respectively. Grade 3/4 thrombocytopenia was rare (1.8% of courses). Peripheral neurotoxicity developed in 25 patients (47.2%), mostly grade 1/2. Arthalgia/myalgia was observed in 30 patients (56.6%), generally grade 1 or 2. Grade 3 abnormal levels of serum glutamate pyruvate transaminase (SGPT) and serum glutamate oxaloacetate transaminase (SGOT) occurred in 5 patients (9.4%) and 1 patient (1.9%), respectively. Combined paclitaxel and gemcitabine is an active and well-tolerated regimen for the treatment of advanced NSCLC, and warrants further investigation in comparative, randomized trials.
