Anaplastic Lymphoma Kinase Inhibitor-Induced Neutropenia: A Systematic Review.

Lung cancers with ALK rearrangement represent less than 5% of all lung cancers. ALK inhibitors are currently used to treat first-line metastatic non-small cell lung cancer with ALK rearrangement. Compared to chemotherapy, ALK inhibitors have improved progression-free survival, overall survival, and quality of life for patients. The results of several phase 3 studies with a follow-up of over 6 years suggest that the life expectancy of these patients treated with targeted therapies is significantly higher than 5 years and could approach 10 years. Nevertheless, these treatments induce haematological toxicities, including neutropenia. Few data are available on neutropenia induced by ALK inhibitors and on the pathophysiological mechanism and therapeutic adaptations necessary to continue the treatment. Given the high efficacy of these treatments, managing side effects to avoid treatment interruptions is essential. Here, we have reviewed the data from published clinical studies and case reports to provide an overview of neutropenia induced by ALK inhibitors.

Real-World Data on Newly Diagnosed BRCA-Mutated High-Grade Epithelial Ovarian Cancers: The French National Multicenter ESME Database.

BACKGROUND: In spite of the frequency and clinical impact of BRCA1/2 alterations in high-grade epithelial ovarian cancer (HGEOC), real-world information based on robust data warehouse has been scarce to date. METHODS: Consecutive patients with BRCA-mutated HGEOC treated between 2011 and 2016 within French comprehensive cancer centers from the Unicancer network were extracted from the ESME database. The main objective of the study was the assessment of clinicopathological and treatments parameters. RESULTS: Out of the 8021 patients included in the ESME database, 266 patients matching the selection criteria were included. BRCA1 mutation was found in 191 (71.8%) patients, while 75 (28.2%) had a BRCA2 mutation only; 95.5% of patients received a cytoreductive surgery. All patients received a taxane/platinum-based chemotherapy (median = six cycles). Complete and partial response were obtained in 53.3% and 20.4% of the cases, respectively. Maintenance therapy was administered in 55.3% of the cases, bevacizumab being the most common agent. After a median follow up of 51.7 months, a median progression-free survival of 28.6 months (95% confidence interval (CI) [26.5; 32.7]) and an estimated 5-year median overall survival of 69.2% (95% CI [61.6; 70.3]) were reported. Notably, BRCA1- and BRCA2-mutated cases exhibited a trend towards different median progression-free survivals, with 28.0 (95% CI [24.4; 32.3]) and 33.3 months (95% CI [26.7; 46.1]), respectively (p-value = 0.053). Furthermore, five-year OS for BRCA1-mutated patients was 64.5% (95% CI [59.7; 69.2]), while it was 82.5% (95% CI [76.6; 88.5]) for BRCA2-mutated ones (p-value = 0.029). CONCLUSIONS: This study reports the largest French multicenter cohort of BRCA-mutated HGEOCs based on robust data from the ESME, exhibiting relevant real-world data regarding this specific population.

Cytoreductive Surgery and Intraperitoneal Chemotherapy in Advanced Serous Epithelial Ovarian Cancer: A 14-Year French Retrospective Single-Center Study of 124 Patients.

INTRODUCTION: Ovarian cancer (OC) is the most lethal gynecological cancer. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy appears to increase survival, and normothermic intraperitoneal chemotherapy (IPC) could improve overall survival (OS). Furthermore, intraperitoneal epinephrine could decrease the toxicity of chemotherapy by decreasing the systemic absorption of chemotherapy. The goal of this study was to assess the effects of CRS and IPC with intraperitoneal epinephrine, as first-line therapy, on the survival of patients with serous epithelial OC (EOC) with peritoneal metastases. METHODS: A prospective monocentric database was retrospectively searched for all patients with advanced serous EOC treated by interval or consolidative CRS plus IPC with intraperitoneal epinephrine after neoadjuvant chemotherapy. OS and disease-free survival (DFS), postoperative complications, and prognostic factors were analyzed. RESULTS: From January 2003 to December 2017, 124 patients with serous EOC were treated with interval (n = 58) or consolidative (n = 66) complete CRS plus IPC with intraperitoneal epinephrine. The median follow-up was 77.8 months, the median OS was 60.8 months, and the median DFS was 21.2 months. In our multivariate analysis, a higher Peritoneal Cancer Index (PCI) and positive lymph node status resulted in worse OS, while higher World Health Organization score, higher PCI score, and positive lymph node status were risk factors for worse DFS. Grade 3 or higher surgical morbidity occurred in 27.42% of cases; only 3.2% had grade 3 renal toxicity and mortality was 0.8%. CONCLUSION: CRS and IPC with intraperitoneal epinephrine in stage III EOC offer good OS and DFS with acceptable morbidity and mortality rates.

Weekly Paclitaxel, Carboplatin, and Cetuximab as First-Line Treatment of Recurrent and/or Metastatic Head and Neck Squamous Cell Carcinoma for Patients Ineligible to Cisplatin-Based Chemotherapy: A Retrospective Monocentric Study in 60 Patients.

OBJECTIVE: For most patients suffering from recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC), chemotherapy is the main option after considering surgery and reirradiation. Cetuximab combined with a platinum-fluorouracil regimen (EXTREME) has been the standard of care for over a decade. Nevertheless, a significant number of patients remain unfit for this regimen because of age, severe comorbidities, or poor performance status. The aim of this study is to investigate an alternative regimen with sufficient efficacy and safety. METHODS: We reviewed retrospectively the medical charts of all patients treated with paclitaxel, carboplatin, and cetuximab (PCC) at our institution. Eligibility criteria were as follows: first-line R/M-HNSCC of the oral cavity, oropharynx, hypopharynx, or larynx not suitable for local therapy, cisplatin, and/or 5-FU ineligibility, ECOG-PS: 0-2. PCC consisted of paclitaxel 80 mg/m2, carboplatin AUC 2, and cetuximab at an initial dose of 400 mg/m2 then 250 mg/m2, for 16 weekly administrations followed by cetuximab maintenance for patients for whom a disease control was obtained. The primary endpoint was overall survival (OS), and secondary endpoints were overall response rate (ORR), progression free survival (PFS), and safety. RESULTS: We identified 60 consecutive patients treated with PCC between 2010 and 2016 at our institution. Thirty-one patients (52%) were ECOG-PS 2. Fifty-five patients (92%) were cisplatin ineligible. ORR was 43.3% (95% CI, 30.8-55.8), and disease control rate was 65% (95% CI, 52.9-77.1). With a median follow-up of 35.7 months (IQR 28.6-48.8), median PFS was 5.8 months (95% CI, 4.5-7.2), and median OS was 11.7 months (95% CI, 7.5-14.8). For ECOG-PS 0-1 patients, median OS was 14.8 months (95% CI, 12.2-21.7) while it was only 7.5 months (95%CI: 5.5-12.7) for ECOG-PS 2 patients (p < 0.04). Grades III-IV toxicities occurred in 30 patients (50%). Most toxicities were hematologic. Six patients (10%) had febrile neutropenia. Nonhematologic toxicities were reported such as cutaneous toxicities, neuropathy, infusion-related reactions, or electrolyte disorders. CONCLUSION: The weekly PCC regimen seems to be an interesting option in cisplatin-unfit patients. This study shows favorable PFS and OS when compared with what is achieved with the EXTREME regimen and a high controlled disease rate with predictable and manageable toxicities even in the more fragile population.

TROIKA-1: A double-blind, randomized, parallel group, study aimed to demonstrate the equivalent pharmacokinetic profile of HD201, a potential biosimilar candidate to trastuzumab, versus EU-Herceptin® and US-Herceptin® in healthy male subjects.

Prestige Biopharma Ltd (Singapore) has developed HD201, a proposed biosimilar to reference product trastuzumab. As a part of the stepwise approach to ensure comparability between the biosimilar candidate and the reference medicinal product, a phase I study in healthy subjects was conducted to demonstrate the pharmacokinetic (PK) equivalence (NCT03776240). The primary objective of the study was to demonstrate (PK) equivalence of HD201, EU-Herceptin® , and US-Herceptin® given at 6 mg/kg as a 90-min i.v. infusion to healthy male subjects. A pairwise comparisons based on the primary endpoint AUC0-inf and secondary PK endpoints, AUC0-last and Cmax were undertaken. PK equivalence was to be concluded if the 90% confidence interval (CI) for the ratio of geometric means for each criterion were within the equivalence margin of 80% to 125%. Secondary objectives included assessment of other PK parameters, safety, tolerability, and immunogenicity in the three arms. A total of 105 healthy male subjects (35/treatment) were randomized in this study. The 90% CI for the ratios of AUC0-inf , Cmax and AUC0-last , were within 80%-125% for the comparisons of HD201 to EU-Herceptin® or US-Herceptin® and EU-Herceptin® to US-Herceptin® . The frequency of subjects with TEAEs of special interest was slightly lower in the HD201 group (20.0%) compared to the other treatment groups (EU-Herceptin® : 34.3%; US-Herceptin® : 31.4%). Only 1 subject (EU-Herceptin® group) developed anti-drug antibodies prior to dosing. Overall, HD201 demonstrates PK similarity to both EU-Herceptin® and US-Herceptin® . The three study drugs also demonstrated similar safety profiles.

Status of Surgical Management of Borderline Ovarian Tumors in France: are Recommendations Being Followed? Multicentric French Study by the FRANCOGYN Group.

BACKGROUND: Borderline ovarian tumors (BOTs) are tumors with a favorable prognosis but whose management by consensus is essential to limit the risk of invasive recurrence. This study aimed to conduct an inventory of surgical practices for BOT in France and to evaluate the conformity of the treatment according to the current French guidelines. METHODS: This retrospective, multicenter cohort study included nine referral centers of France between January 2001 and December 2018. It analyzed all patients with serous and mucinous BOT who had undergone surgery. A peritoneal staging in accordance with the recommendations was defined by performance of a peritoneal cytology, an omentectomy, and at least one peritoneal biopsy. RESULTS: The study included 332 patients. A laparoscopy was performed in 79.5% of the cases. Treatment was conservative in 31.9% of the cases. The recurrence rate was significantly increased after conservative treatment (17.3% vs 3.1%; p < 0.001). Peritoneal cytology was performed for 95.5%, omentectomy for 83.1%, and at least one biopsy for 82.2% of the patients. The overall recurrence rate was 7.8%, and the recurrence was invasive in 1.2% of the cases. No link was found between the recurrence rate and the conformity of peritoneal staging. The overall rate of staging noncompliance was 22.9%. CONCLUSION: The current standards for BOT management seem to be well applied.

Exposure-response analysis of Raltitrexed assessing liver toxicity.

AIM: Raltitrexed (RTX) is a thymidylate synthase inhibitor with large pharmacokinetics (PK) variability that can be administered in case of 5-fluorouracil (5FU) intolerance or dihydropyrimidine dehydrogenase deficiency. While it is a more potent thymidylate synthase inhibitor than 5FU, RTX failed to replace this drug for colorectal cancer patients, mainly due to its toxicity at the recommended dose of 3 mg/m2 every 3 weeks. However, every 2 weeks administration at 2 mg/m2 demonstrated a favourable toxicity profile. METHOD: We performed a randomized crossover comparative population PK study between every 2 weeks TOMOX (RTX 2 mg/m2 ) and every 3 weeks TOMOX (RTX 3 mg/m2 ). RESULTS: A three-compartment model and a proportional error model best describe the data. Creatinine clearance and sex, but not body surface area (BSA), were covariates of RTX clearance leading to decrease of its interindividual variability of 28%. Weight and body surface area were covariates of central and peripheral volumes of distribution, respectively, leading to decreases of interindividual variability of 34.6% and 100%, respectively. In contrast to the dose, AUC was a good predictor of liver toxicity (P = 0.006, OR = 3.91, 95%CI = [1.48-10.34]). Using covariates to compute individual clearance and a threshold AUC (1.639, determined in this study), a covariates-based dose was calculated, leading to less variability in AUC than observed with the actual BSA-based or fixed doses. CONCLUSION: These results advocate for the use of creatinine clearance and sex to determine the RTX dose instead of BSA.

18F-FDG PET/CT Imaging of Peritoneal Fibrosis Mimicking Persistent Metastatic Ovarian Carcinoma.

A 65-year-old woman was addressed for clinical and biological suspicion of ovarian cancer relapse. 18F-FDG PET/CT revealed massive peritoneal carcinomatosis. Post-chemotherapy PET/CT showed complete metabolic response in initial localizations albeit three new 18F-FDG uptakes appeared in the mesentery and in the retro-hepatic space. Close follow-up (including PET/CT scan) and surgical examination of the abdominal cavity confirmed the absence of malignancy and the benign nature of these lesions, which appeared to be peritoneal fibrosis mimicking persistent carcinomatosis.

Evolution of Physical Status From Diagnosis to the End of First-Line Treatment in Breast, Lung, and Colorectal Cancer Patients: The PROTECT-01 Cohort Study Protocol.

Background: Cancer cachexia and exacerbated fatigue represent two hallmarks in cancer patients, negatively impacting their exercise tolerance and ultimately their quality of life. However, the characterization of patients' physical status and exercise tolerance and, most importantly, their evolution throughout cancer treatment may represent the first step in efficiently counteracting their development with prescribed and tailored exercise training. In this context, the aim of the PROTECT-01 study will be to investigate the evolution of physical status, from diagnosis to the end of first-line treatment, of patients with one of the three most common cancers (i.e., lung, breast, and colorectal). Methods: The PROTECT-01 cohort study will include 300 patients equally divided between lung, breast and colorectal cancer. Patients will perform a series of assessments at three visits throughout the treatment: (1) between the date of diagnosis and the start of treatment, (2) 8 weeks after the start of treatment, and (3) after the completion of first-line treatment or at the 6-months mark, whichever occurs first. For each of the three visits, subjective and objective fatigue, maximal voluntary force, body composition, cachexia, physical activity level, quality of life, respiratory function, overall physical performance, and exercise tolerance will be assessed. Discussion: The present study is aimed at identifying the nature and severity of maladaptation related to exercise intolerance in the three most common cancers. Therefore, our results should contribute to the delineation of the needs of each group of patients and to the determination of the most valuable exercise interventions in order to counteract these maladaptations. This descriptive and comprehensive approach is a prerequisite in order to elaborate, through future interventional research projects, tailored exercise strategies to counteract specific symptoms that are potentially cancer type-dependent and, in fine, to improve the health and quality of life of cancer patients. Moreover, our concomitant focus on fatigue and cachexia will provide insightful information about two factors that may have substantial interaction but require further investigation. Trial registration: This prospective study has been registered at ClinicalTrials.gov (NCT03956641), May, 2019.

Impact of Lymphadenectomy on Survival of Patients with Serous Advanced Ovarian Cancer After Neoadjuvant Chemotherapy: A French National Multicenter Study (FRANCOGYN).

BACKGROUND: The population of interest to this study comprised individuals with advanced-stage ovarian carcinoma who were exposed to neoadjuvant chemotherapy (NAC) followed by interval debulking surgery (IDS). Those who had not received systematic lymphadenectomy (SL; Group 1) were compared to those who had received SL (Group 2). Outcome measures included progression-free survival (PFS), overall survival (OS), and surgical complications. METHODS: This was a retrospective, multicenter cohort study in nine referral centers of France between January 2000 and June 2017. OS analysis using the multivariate Cox regression model was performed. PFS and surgery-related morbidity were analyzed. RESULTS: Of the 255 patients included, 100 were in Group 1 and 155 in Group 2. Patient majority was, on average, younger and less comorbid, with predominant R0 surgery in Group 2. Dindo-Clavien score was similar between the two groups (p = 0.15). Median OS was 26.8 months in Group 2 and 27.6 months in Group 1. SL was not statistically significant on OS (p = 0.7). Median PFS was 18.3 months in Group 2 and 16.6 months in Group 1. SL had positive impact on PFS (p = 0.005). CONCLUSIONS: patients who had received SL (Group 2) had significantly higher PFS regardless of node-positivity status when compared to those who had not received SL (Group 1).

Interest to consider re-challenging by cetuximab and platinum containing regimen in recurrent Head and Neck Cancer.

BACKGROUND: The EXTREME protocol is the standard of care for recurrent or metastatic head and neck squamous-cell carcinoma (R/M HNSCC) in first line. Beyond the first-line except immunotherapy, poor efficacy was reported by second-line chemotherapy. Re-challenge strategies based on a repetition of the first line with platinum and cetuximab regimens might have been an option to consider. METHODS: We performed a retrospective study in order to assess the efficacy of the cetuximab plus platinum doublet-based chemotherapy regimen in patients with R/M HNSCC progressing after at least 3 months of cetuximab maintenance (EXTREME protocol). We complete a retrospective review of all medical records from R/M HNSCC patients treated after 16 weeks with the EXTREME regimen and treated with a re-challenge strategy between January 2010 and December 2014 in our institution (Centre Paul Strauss, Strasbourg, France). RESULTS: 33 patients were identified. The re-challenged strategy provided an ORR in 33.3% of cases and a DCR of 69.6% of cases. The median OS and PFS observed from the second line were 11.2 months and 6.5 months for the subset re-challenged by EXTREME or PCC regimens respectively. The response rate between patients with a platin free interval within 3 and 6 months and greater than 6 months were equal. Drugs dose intensity were better with the PCC protocol than the EXTREME regimen used as a rechallenge. CONCLUSIONS: This study suggest re-challenging strategy by these regimens could be considered beyond the first line as an option when the platin free interval is greater than 3 months.

[Prevalence and management of pain in patients with metastatic cancer in Franche-Comté]. / Prévalence et prise en charge de la douleur chez les patients présentant un cancer métastatique en Franche-Comté.

INTRODUCTION: Pain management is a major public health problem, especially in oncology. In order to assess professional practice, the IRFC-FC conducted a survey amongst patients with metastatic osteophilic solid tumor in Franche-Comté. The aims were to assess the pain prevalence, and its characteristics, its management and its impact on patients' quality of life in patients in pain. METHODS: An observational, prospective and multicenter survey was conducted using a self-report questionnaire. Patients with metastatic breast or prostate cancer managed in 5 day-hospitals of the IRFC-FC over a period of three months were included. RESULTS: Two hundred thirty-three questionnaires were analyzed. Pain prevalence rate was 48.5%. Three quarters of patients in pain had chronic background pain, moderate to severe, with or without breakthrough pain. Considering their pain intensity and their analgesic therapy, 42.0% of patients seem to have an inadequate treatment. Eighty-five percent of treated patients reported to be compliant and felt that their pain was well managed despite a strong impact on their quality of life. CONCLUSION: The setting of a specific clinical pathway is essential to secure the standardized, optimal and efficient management of patients in pain. The assessment of patient satisfaction and quality of life must be integrated in clinical practice to identify patients in pain for which the treatment is inappropriate.

Impact of Chemotherapy Beyond the Third Line in Patients With Recurrent Epithelial Ovarian Cancer.

OBJECTIVES: The goal of this study was to determine the benefit in terms of time disease control (TDC) achieved by the succession of chemotherapy beyond the third line in patients treated for recurrent epithelial ovarian cancer. Secondary objectives were to identify patients who benefited from treatments beyond 3 lines and to estimate overall survival and disease-free progression lengths. MATERIALS AND METHODS: The cohort of 122 patients was identified from a pharmacy database of patients treated with chemotherapy between 1992 and 2010. The evaluation of benefit obtained by each line was based on TDC duration, defined as the interval between the beginning of the treatment and the date of progressive disease or death. RESULTS: Median TDC durations was 4.15 (0-54.7), 4 (0-21.7), 3.34 (0-29.6), 4.97 (0-29.2), and 3.13 months (0-15) for the fourth to eighth lines, respectively. Time to disease control was longer than 6 months in 34% to 40% of patients treated by lines 4 to 8. The most important factor influencing TDC length beyond the third line was the TDC duration observed in the 2 previous lines of therapy. Median overall survival after the third line was 15.3 months (95% confidence interval, 12-20 months). Factors associated with longer overall survival after 3 lines were performance status lower than 2 (P = 0.0058), no hepatic metastasis (P = 0.0098), no pulmonary metastasis (P = 0.0003), and platinum sensitivity (P = 0.04) CONCLUSIONS: These results may justify the administration of chemotherapy beyond the third line, in particular when the 2 previous lines are effective and resulted in disease control longer than 6 months.

Advanced biliary tract carcinomas: a retrospective multicenter analysis of first and second-line chemotherapy.

BACKGROUND: Gemcitabine/Cisplatin (Gem/CDDP) combination has demonstrated a clear survival advantage over gemcitabine alone and has become a new standard in advanced Biliary Tract Carcinoma (aBTC). However, Gemcitabine/Oxaliplatin (GEMOX) combination and Gemcitabine/Carboplatin (Gem/Carb) combination regimens have shown efficacy in phase II trials and there is no comparative study between different platinum salts.We assessed the efficacy and safety of different platinum-based chemotherapies at first line in aBTC patients. We also analysed the second-line chemotherapy. METHODS: Sixty-four consecutive patients with aBTC diagnosed between 1998 and 2010 were included for analysis. At first line chemotherapy, 44 patients received one day GEMOX regimen (gemcitabine 1000 mg/m2 and oxaliplatin 100 mg/m2 Day 1, every 2 weeks), and 20 patients received Gem/Carb regimen (gemcitabine at 1000 mg/m2 Days 1 and 8 with carboplatin delivered according to an area-under-the-curve (AUC) 5 at day 1, every 3 weeks). At second line, a total of 16 patients received a fluoropyrimidine-based chemotherapy. RESULTS: With GEMOX regimen, median progression-free survival (PFS) was 3.7 months (95%CI, 2.4 to 5) and median overall survival (OS) was 10.5 months (95%CI, 6.4 to14.7). The main toxicity was peripheral neuropathy (20% grade 2 and 7% grade 3). Grade 3/4 haematological toxicities were rare.With Gem/Carb regimen, PFS was 2.5 months (95%CI, 2.1 to 3.7) and OS was 4.8 months (95%CI, 3.7 to 5.8). The main grade 3/4 toxicities were haematological: anaemia (45%), thrombocytopenia (45%), and neutropenia (40%).At second-line, fluoropyrimidine-based chemotherapy was feasible in only a fourth of the patients. The median OS was 5.3 months (95%CI, 4.1 to 6.6), and median PFS was 4.0 months (95%CI, 2.6 to 5.5). CONCLUSIONS: One day GEMOX regimen has a favourable toxicity profile and could be an alternative to standard Gem/CDDP regimen, in particular in unfit patients for CDDP.At second-line, selective patients may benefit from fluoropyrimidine-based chemotherapy.

Cisplatin/gemcitabine or oxaliplatin/gemcitabine in the treatment of advanced biliary tract cancer: a systematic review.

Cisplatin/gemcitabine association has been a standard of care for first-line regimen in advanced biliary tract cancer nevertheless oxaliplatin/gemcitabine regimen is frequently preferred. Because comparative effectiveness in clinical outcomes of cisplatin- versus oxaliplatin-containing chemotherapy is not available, a systematic review of studies assessing cisplatin/gemcitabine or oxaliplatin/gemcitabine chemotherapies in advanced biliary tract cancer was performed. Published studies evaluating cisplatin/gemcitabine or oxaliplatin/gemcitabine in advanced biliary tract cancer were included. Each study was weighted according to the number of patients included. The primary objective was to assess weighted median of medians overall survival (mOS) reported for both regimens. Secondary goals were to assess weighted median of medians progression-free survival (mPFS) and toxic effects were pooled and compared within each arm. Thirty-three studies involving 1470 patients were analyzed. In total, 771 and 699 patients were treated by cisplatin/gemcitabine and oxaliplatin/gemcitabine, respectively. Weighted median of mOS was 9.7 months in cisplatin group and 9.5 months in oxaliplatin group. Cisplatin-based chemotherapy was significantly associated with more grade 3 and 4 asthenia, diarrhea, liver toxicity, and hematological toxicity. Sensitivity analysis including only the studies with the standard regimen of cisplatin (25-35 mg/m(2) administered on days 1 and 8) showed that the weighted median of mOS increased from 9.7 to 11.7 months but Gem/CDDP regimen remained more toxic than Gemox regimen. These results suggest that the Gem/CDDP regimen with cisplatin (25-35 mg/m(2)) administered on days 1 and 8 is associated with survival advantage than Gemox regimen but with addition of toxicity.

Bifractionated CPT-11 with LV5FU2 infusion (FOLFIRI-3) in combination with bevacizumab: clinical outcomes in first-line metastatic colorectal cancers according to plasma angiopoietin-2 levels.

BACKGROUND: Optimization of chemotherapy effectiveness in metastatic colorectal cancers (mCRC) is a major endpoint to enhance the possibility of curative intent surgery. FOLFIRI3 has shown promising results as second-line chemotherapy for mCRC patients previously exposed to oxaliplatin. The clinical efficacy of FOLFIRI3 was never determined in association with bevacizumab in non-previously treated mCRC patients. METHODS: We conducted a phase II clinical trial to characterize the response rate and toxicity profile of FOLFIRI3-bevacizumab as initial treatment for mCRC. Sixty-one patients enrolled in 3 investigation centers were treated with FOLFIRI3-bevacizumab (median of 10 cycles) followed by a maintenance therapy combining bevacizumab and capecitabine. Levels of plasma angiopoietin-2 (Ang-2) were measured by enzyme-linked immunosorbent assay at baseline. RESULTS: Overall response rate (ORR) was 66.7% (8% of complete and 58% of partial responses). The disease control rate was 91.7%. After a median time of follow-up of 46.7 months, 56 patients (92%) had progressed or died. The median progression free survival (PFS) was 12.7 months (95% confidence interval (CI) 9.7-15.8 months). The median overall survival (OS) was 24.5 months (95% CI: 10.6-38.3 months). Twenty-one patients underwent curative intent-surgery including 4 patients with disease initially classified as unresectable. Most common grade III-IV toxicities were diarrhea (15%), neutropenia (13%), asthenia (10%), and infections (4%). Hypertension-related medications needed to be increased in 3 patients. In multivariate analysis, surgery of metastases and Ang-2 levels were the only independent prognostic factors for PFS and OS. Indeed, baseline level of Ang-2 above 5 ng/mL was confirmed as an independent prognostic factor for progression free survival (HR = 0.357; 95% CI: 0.168-0.76, p = 0.005) and overall survival (HR = 0.226; 95% CI: 0.098-0.53, p = 0.0002). CONCLUSIONS: As front-line therapy, FOLFIRI-3-bevacizumab is associated with an acceptable toxicity and induced promising objective response rates. However, unfavorable clinical outcomes were observed in patients with high levels of angiopoietin-2.

Is extracapsular tumour spread a prognostic factor in patients with early breast cancer?

BACKGROUND: This study searched for extra capsular tumour spread (ECS) as a prognostic factor for recurrence in terms of Disease Free Survival (DFS) and Overall Survival (OS). PATIENTS AND METHODS: For this study, from a retrospective database of the Doubs cancer registry, 823 eligible women with node positive breast cancer treated from February 1984 to November 2000 were identified. The following factors were evaluated: ECS, numbers of involved nodes, histological tumour grade, tumour size, status of estrogen and progesterone receptors, and age of patient. A Cox proportional hazards method was used to search for significant factors related to OS and DFS length. RESULTS: In the multivariate analysis, factors related to DFS length were found to be: tumour grade (aHR 0.76, 95 % CI 0.61-0.96, p = 0.02), ECS status (aHR 0.7, 95 % CI 0.49-0.96, p = 0.03), progesterone (PgR) status (aHR 0.63, 95 % CI 0.44-0.85 p = 0.008), number of nodes involved (aHR 0.75, 95 % CI 0.56-1, p = 0.05). The multivariate analysis for OS found as significant factors: tumour grade (aHR 0.76, 95 % CI 0.61-0.95; p = 0.02) and PgR status (aHR 0.8, 95 % CI 0.56-0.99, p = 0.02). CONCLUSIONS: This study might suggest taking into account ECS status in the adjuvant decision-making process.

Impact of STAT3 phosphorylation on the clinical effectiveness of anti-EGFR-based therapy in patients with metastatic colorectal cancer.

UNLABELLED: Half of patients with KRAS wild-type colorectal cancer do not benefit from adding anti-epithelial growth factor receptor (EGFR) to standard chemotherapy regimens. This retrospective study was performed in 94 patients with metastatic colorectal cancer (mCRC) treated in the second line with cetuximab and chemotherapy. Signal transducer and activator of transcription 3 (STAT3) phosphorylation in tumor cells was correlated with decreased median progression-free survival and overall survival (OS). These results highlight the potential role of STAT3 as a molecular target to optimize anti-EGFR therapies. BACKGROUND: Signal transducer and activator of transcription 3 (STAT3) is involved in epithelial growth factor receptor (EGFR) signaling in a KRAS-independent manner. Phosphorylated STAT3 (pSTAT3) expression in patients with metastatic colorectal cancer (mCRC) treated with anti-EGFR-containing salvage chemotherapy has never been investigated. PATIENTS AND METHODS: : The first endpoint of this retrospective study was to evaluate the impact of pSTAT3 on the time to progression (TTP) in 94 patients with mCRC treated with anti-EGFR-based therapies in the second- or third-line setting between July 2004 and November 2009. The influence of pSTAT3 on objective response rate and overall survival (OS) was also reported. Nuclear expression of pSTAT3 status was evaluated by immunohistochemical tests on formalin-fixed and paraffin-embedded tumor samples obtained before therapy. RESULTS: Positive expression of pSTAT3 was observed in 24.5% of the tumor samples. The probability of achieving an objective response was 13% among patients with positive nuclear expression of pSTAT3 compared with 41% for patients displaying pSTAT3-negative tumors (P = .02). In a multivariate logistic regression model, high-grade skin rash, wild-type KRAS status, and negative pSTAT3 status significantly improved TTP and OS. CONCLUSION: These results underscore an impact of pSTAT3 on the clinical efficacy of anti-EGFR-containing chemotherapy regimens and support the prospective assessment of this biomarker.

Extravasation of liposomal doxorubicin induces irritant reaction without vesicant injury.

Anthracycline extravasation is an uncommon but very serious complication. Very few data are available in the literature concerning the consequences and the management of extravasation of liposomal doxorubicin. This report describes the cases of two patients with liposomal doxorubicin extravasation who developed irritant reaction without vesicant or necrotic lesions. It is concordant with other cases described in the literature and suggests that extravasation of liposomal doxorubicin can be relatively well tolerated. The process applied to extravasations of irritant and non-vesicant agents could be used to manage extravasations of liposomal doxorubicin.

Cabazitaxel: a novel microtubule inhibitor.

The development of drug resistance is a major obstacle to effective cancer therapy. Several agents are in clinical development with the goal of overcoming resistance. Among them is cabazitaxel, a semisynthetic taxoid that is able to overcome a common mechanism of resistance that limits the efficacy of other chemotherapeutic agents, including the older taxanes. The promise of cabazitaxel as a second-line chemotherapy option for advanced prostate cancer has been confirmed clinically in the phase III TROPIC (Treatment of Hormone-Refractory Metastatic Prostate Cancer Previously Treated with a Taxotere-Containing Regimen) trial. This trial showed that cabazitaxel is the first chemotherapeutic agent to demonstrate a survival benefit in metastatic castration-resistant prostate cancer (mCRPC) since the approval of docetaxel. On this basis, the US FDA and the European Medicines Agency approved cabazitaxel in June 2010 and January 2011, respectively, for the treatment of patients with mCRPC who have previously been treated with docetaxel. The most prevalent toxicity was neutropenia and the use of primary prophylaxis with granulocyte-colony stimulating factor is recommended in high risk patients. This article presents the preliminary antitumour activity, safety, tolerability and pharmacokinetic data of cabazitaxel, and an overview of the current status of clinical development.
