Comparison of tumor response by Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST in patients treated with sorafenib for hepatocellular carcinoma.

BACKGROUND: A significant improvement in overall survival (OS) was demonstrated in patients with advanced hepatocellular carcinoma (HCC) who received sorafenib (Sor) in the Sorafenib HCC Assessment Randomized Protocol (SHARP) study, in contrast to a response rate (RR) of 2% assessed according to Response Evaluation Criteria in Solid Tumors (RECIST). Modified RECIST (mRECIST) were developed to assess the response in patients with HCC, based on measurement of viable tumor with arterial enhancement on a computed tomography (CT) scan. In the current study, mRECIST were evaluated and were compared with RECIST in patients who received Sor for advanced HCC. METHODS: The authors retrospectively analyzed 53 patients who received Sor for advanced HCC. Patients must to have undergone a 4-phase CT scan before treatment and repeatedly thereafter. CT scans were analyzed using RECIST 1.1 and mRECIST. RESULTS: The rates of objective response (OR), stable disease (SD), and progressive disease (PD) were 2%, 79%, and 19%, respectively, according to RECIST and 23%, 57%, and 21%, respectively, according to mRECIST (P < .001). Patients who achieved an OR according to mRECIST had a longer OS than nonresponding patients with SD or PD (median OS, 18 months and 8 months, respectively; P = .013). In the 42 patients who achieved SD according to RECIST, OS differed depending on tumor response according to mRECIST, with a median OS of 17 months, 10 months, and 4 months for patients who achieved an OR (n = 11), SD (n = 29), and PD (n = 2), respectively (P = .016). CONCLUSIONS: The current series validated mRECIST in patients who received Sor for advanced HCC. The majority of patients who had SD according to RECIST had a different prognosis according to mRECIST. The results indicated that, for patients with HCC, mRECIST should be used for the standard assessment of treatment efficacy, particularly in patients who are receiving antiangiogenic drugs.

Cementoplasty for painful bone metastases: a series of 42 cases.

The aim of this study is to assess the interest of cementoplasty in the management of bone metastases, based on a retrospective study involving 42 cementoplasty procedures. The median age of the patients is 59 years, with 24 women (57%) and 18 men, all of them presenting with an advanced disease. The cementoplasty was situated in long bones (ten patients), dorsal or lumbar vertebrae (13) and flat bones (20). The principal indication was pain, sometimes with consolidation. The intensity of pain decreases between the day before and the month following the treatment (P = 0.04) among the 25 patients who had pain assessment before and after the procedure. We note 57% good results (24 patients), 9.5% failures (4 patients), and 31% with partial results (13 patients), that is, a total of 88% with "partial or full" alleviation. 16 patients out of 22 (73%) who were no longer able to walk (because of the pain or risk of fracture) were able to resume walking. We observed in this series 40.5% of complications, all of them benign. Cementoplasty improves the quality of life of patients with bone metastases, by decreasing the pain in 88% of cases and allowing the resumption of walking in almost three-quarters of the patients who had lost the ability to walk.

Clubbing and hypertrophic osteoarthropathy in two patients taking long-term bevacizumab for metastatic colorectal cancer.

INTRODUCTION: The authors report two cases of young patients who developed clubbing and hypertrophic osteoarthropathy in one case or lung diffusion disorder in the second, after a long-term use of bevacizumab plus chemotherapy in a palliative setting of metastatic colorectal cancer. DISCUSSION: We propose that patients on long-term bevacizumab be examined for clubbing and undergo respiratory function tests and that this would be studied prospectively before beginning trials in evaluating this monoclonal antibody given for 2 years in an adjuvant setting.

Relapse factors for ileal neuroendocrine tumours after curative surgery: a retrospective French multicentre study.

AIM: To evaluate the characteristics of postoperative relapse, predictive factors and time to relapse after curative surgery for well-differentiated neuroendocrine tumours of the ileum, without hepatic or other distant metastases. METHODS: Clinical data of patients entered into the Groupe d'étude des Tumeurs Endocrines database were collected and analysed retrospectively to identify factors predictive of relapse. RESULTS: Among 100 patients followed for a median of 56.5 (range 1-290) months, 42 relapsed after a median follow-up of 57.5 (range 6-176) months, with liver lesions in 27 (64.3%). Median disease-free survival (Kaplan-Meier) was 88 months (95% confidence interval 72-115). Disease-free survival was shorter for emergency surgery patients (p<0.01), patients with distant mesenteric lymph-node metastases (p<0.01), with fortuitous diagnosis (p=0.02), with tumour diameter >20mm (p=0.02), and those with multiple tumours (p=0.07). Multivariate analysis retained emergency surgery (odds-ratio 4.04 [95% confidence interval 2.01-8.11]), distant mesenteric lymph-node metastases (odds-ratio 2.53 [95% confidence interval 1.22-5.25]), and multiple tumours (odds-ratio 2.14 [95% confidence interval 1.01-4.50]), as being significantly associated with relapse. CONCLUSION: Patients who underwent emergency surgery, with distant mesenteric lymph-node metastases or with multiple ileal tumours relapsed earlier. Closer monitoring for the patients with these risk factors may be required.
