RESUMO
OBJECTIVE: The aim of this study was to compare surgical complexity, post-operative complications, and survival outcomes between patients with minimal residual disease (completeness of cytoreduction (CC) score) CC-1 at the time of primary debulking surgery and those with complete cytoreduction (CC-0) at the time of interval debulking surgery. METHODS: A retrospective multicenter study was conducted of patients with advanced ovarian cancer (International Federation of Gynecology and Obstetrics stage IIIC-IV) who underwent cytoreductive surgery achieving either minimal or no residual disease between January 2008 and December 2015. Patients underwent either primary or interval debulking surgery after receiving ≥3 cycles of neoadjuvant chemotherapy. The sub-group of patients with primary debulking surgery/CC-1 was compared with those with interval debulking surgery/CC-0. Overall survival and disease-free survival were estimated using the Kaplan-Meier method. RESULTS: A total of 549 patients were included, with upfront surgery performed in 175 patients (31.9%) and 374 patients (68.1%) undergoing interval debulking surgery. After primary debulking surgery, 157/175 (89.7%) had complete cytoreduction and 18/175 (10.3%) had minimal residual disease (primary debulking surgery/CC-1 group), while after interval debulking surgery, 324/374 (86.6%) had complete cytoreduction (interval debulking surgery/CC-0 group) and 50/374 (13.4%) had minimal residual disease. The rate of patients with peritoneal cancer index >10 was 14/17 (82.4%) for the primary debulking surgery/CC-1 group and 129/322 (40.1%) for the interval debulking surgery/CC-0 (p<0.001). The rate of patients with an Aletti score of ≥8 was 11/18 (61.1%) and 132/324 (40.7%), respectively (p=0.09) and the rate of major post-operative complications was 5/18 (27.8%) and 64/324 (19.8%), respectively (p=0.38). Overall median disease-free and overall survival were 19.4 months (95% CI 18.0 to 20.6) and 56.7 months (95%CI 50.2 to 65.8), respectively. Median disease-free survival for the primary debulking surgery/CC-1 group was 16.7 months (95% CI 13.6 to 20.0) versus 18.2 months (95% CI 16.4 to 20.0) for the interval debulking surgery/CC-0 group (p=0.56). Median overall survival for the primary debulking surgery/CC-1 group was 44.7 months (95% CI 34.3 to not reached) and 49.4 months (95% CI 46.2 to 57.3) for the interval debulking surgery/CC-0 group (p=0.97). CONCLUSIONS: Patients with primary debulking surgery with minimal residual disease and those with interval debulking surgery with no residual disease had similar survival outcomes. Interval surgery should be considered when achieving absence of residual disease is challenging at upfront surgery, given the lower tumor burden found during surgery.
RESUMO
Objective: As craniospinal irradiation (CSI) is delivered more frequently by helical tomotherapy (HT) with few reports about late effects, we analysed all patients treated in our centre over an 11-year period. Methods and materials: Our study included all patients that underwent CSI by HT, between September 2009 and January 2020, in the Department of Radiation Oncology of the Toulouse Cancer Institute. Acute radiotherapy toxicities were reported and medium- to long-term outcomes analysed. Results: Among the 79 patients included, 70.9 % were younger than 18 years at diagnosis, the median age was 13 (range: 1-52) at the time of radiation therapy, 67.1 % of patients had medulloblastoma. Half of them (49.4 %) had a metastatic disease at diagnosis. The median dose of CSI was 36 Gy (range, 18-36). Seventy-seven patients received a radiation boost to the original location of the primary tumour (97.5 %), 32 patients also received a boost to their metastatic sites (40.5 %). Median follow-up was 55.5 months (95 %CI = [41.2; 71.8]). The 3-year event-free survival rate was 66.3 % (95 %CI = [54.2; 75.9]). Most patients presented with acute haematological toxicities during CSI (85.9 %), predominantly severe thrombocytopenia (39.7 %). Among the 64 patients assessed for medium- and long-term outcomes, 52 survived and 47 were alive and disease-free at the latest follow-up visit on record. There were 3.8 % secondary tumours: two meningiomas and one diffuse intrinsic pontine glioma. Adult and paediatric patients respectively presented with secondary cataract (4.3 % vs 22.0 %), persistent hearing disorders (26.1 % vs 29.3 %), pulmonary or cardiac late effects (4.3 % vs 2.4 %), hormonal pituitary gland deficiencies (30.0 % vs 56.8 %) and psycho-cognitive disorders (56.5 % vs 53.7 %). Conclusion: CSI dispensed by HT, did not result in any additional acute or late toxicities when compared to 3D-CSI. There was no increase in the secondary tumour rate compared to that reported in the literature.
RESUMO
INTRODUCTION: In France, 40% of patients diagnosed with lung cancer are ≥70 years old, but these are under-represented in clinical trials. Using data from the French Epidemiological Strategy and Medical Economics (ESME) platform on Lung Cancer (LC), the objective is to provide an overview of the management and the prognosis of older patients with advanced or metastatic non-small cell lung cancer (AM-NSCLC) in a real-world context. MATERIALS AND METHODS: From the ESME-LC database, we selected patients with AM-NSCLC (stage IIIB, IIIC, and IV), diagnosed between 2015 and 2019, and who received first-line systemic treatment. Demographics, tumour characteristics, and treatment received were described in patients ≥70, and compared to younger ones. Real-world progression-free survival (rwPFS) and overall survival (OS) were evaluated using the multivariable Cox model. RESULTS: Among 10,002 patients with AM-NSCLC, the median age was 64 years, with 2,754 (27.5%) aged ≥70. In comparison with patients <70, older patients were more often male, with worse performance status and more comorbidities, but they were less underweight and more often non-smokers. The proportion of EGFR mutated non-squamous NSCLC was higher in older patients (25.0% vs 12.8%, p < 0.001), particularly among smokers and former smokers (12.7% vs 7.3%, p < 0.001). Among patients ≥70, 76.6% received first-line chemotherapy (including 67.0% treated with a platinum-based doublet), 15.0% received only targeted therapy, and 11.0% received immunotherapy (alone or in combination). Median first-line rwPFS was 5.1 months (95% confidence interval [CI] = [4.8;5.4]) for patients ≥70 and 4.6 months (95%CI = [4.4;4.8]) for patients <70, but age was not associated with rwPFS in multivariable analysis. Median OS was 14.8 months (95%CI = [13.9;16.1]) for patients ≥70 and 16.7 months (95%CI = [15.9;17.5]) for patients <70, with a significant effect of age in multivariable analysis for patients treated with chemotherapy and/or with targeted therapy, but not for patients treated with immunotherapy (alone or in combination with chemotherapy). DISCUSSION: In this real-world cohort of patients with AM-NSCLC, age was not associated with first-line rwPFS regardless of treatment received, nor with OS for patients receiving immunotherapy. However, OS was significantly shorter for patients aged ≥70 treated with chemotherapy or with targeted therapy alone.
