Quality of life in patients with metastatic prostate cancer following treatment with cabazitaxel versus abiraterone or enzalutamide (CARD): an analysis of a randomised, multicentre, open-label, phase 4 study.

BACKGROUND: In the CARD study, cabazitaxel significantly improved radiographic progression-free survival and overall survival versus abiraterone or enzalutamide in patients with metastatic castration-resistant prostate cancer previously treated with docetaxel and the alternative androgen signalling-targeted inhibitor. Here, we report the quality-of-life outcomes from the CARD study. METHODS: CARD was a randomised, multicentre, open-label, phase 4 study involving 62 clinical sites across 13 European countries. Patients (aged ≥18 years, Eastern Cooperative Oncology Group (ECOG) performance status ≤2) with confirmed metastatic castration-resistant prostate cancer were randomly assigned (1:1) by means of an interactive voice-web response system to receive cabazitaxel (25 mg/m2 intravenously every 3 weeks, 10 mg daily prednisone, and granulocyte colony-stimulating factor) versus abiraterone (1000 mg orally once daily plus 5 mg prednisone twice daily) or enzalutamide (160 mg orally daily). Stratification factors were ECOG performance status, time to disease progression on the previous androgen signalling-targeted inhibitor, and timing of the previous androgen signalling-targeted inhibitor. The primary endpoint was radiographic progression-free survival; here, we present more detailed analyses of pain (assessed using item 3 on the Brief Pain Inventory-Short Form [BPI-SF]) and symptomatic skeletal events, alongside preplanned patient-reported outcomes, assessed using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire and the EuroQoL-5 dimensions, 5 level scale (EQ-5D-5L). Efficacy analyses were done in the intention-to-treat population. Pain response was analysed in the intention-to-treat population with baseline and at least one post-baseline assessment of BPI-SF item 3, and patient-reported outcomes (PROs) were analysed in the intention-to-treat population with baseline and at least one post-baseline assessment of either FACT-P or EQ-5D-5L (PRO population). Analyses of skeletal-related events were also done in the intention-to-treat population. The CARD study is registered with ClinicalTrials.gov, NCT02485691, and is no longer enrolling. FINDINGS: Between Nov 17, 2015, and Nov 28, 2018, of 303 patients screened, 255 were randomly assigned to cabazitaxel (n=129) or abiraterone or enzalutamide (n=126). Median follow-up was 9·2 months (IQR 5·6-13·1). Pain response was observed in 51 (46%) of 111 patients with cabazitaxel and 21 (19%) of 109 patients with abiraterone or enzalutamide (p<0·0001). Median time to pain progression was not estimable (NE; 95% CI NE-NE) with cabazitaxel and 8·5 months (4·9-NE) with abiraterone or enzalutamide (hazard ratio [HR] 0·55, 95% CI 0·32-0·97; log-rank p=0·035). Median time to symptomatic skeletal events was NE (95% CI 20·0-NE) with cabazitaxel and 16·7 months (10·8-NE) with abiraterone or enzalutamide (HR 0·59, 95% CI 0·35-1·01; log-rank p=0·050). Median time to FACT-P total score deterioration was 14·8 months (95% CI 6·3-NE) with cabazitaxel and 8·9 months (6·3-NE) with abiraterone or enzalutamide (HR 0·72, 95% CI 0·44-1·20; log-rank p=0·21). There was a significant treatment effect seen in changes from baseline in EQ-5D-5L utility index score in favour of cabazitaxel over abiraterone or enzalutamide (p=0·030) but no difference between treatment groups for change from baseline in EQ-5D-5L visual analogue scale (p=0·060). INTERPRETATION: Since cabazitaxel improved pain response, time to pain progression, time to symptomatic skeletal events, and EQ-5D-5L utility index, clinicians and patients with metastatic castration-resistant prostate cancer can be reassured that cabazitaxel will not reduce quality of life when compared with treatment with a second androgen signalling-targeted inhibitor.

Supportive medication in cancer during pregnancy.

While pregnancy-related malignancies are quite rare, their incidence is increasing and thus affecting more and more women nowadays. Their management, however, with both chemotherapy and supportive agents remains quite challenging and it seems crucial to define the optimal treatment for this special population. Concerning supportive medication, it is clinically significant to determine whether commonly used agents, including Granulocyte Colony-Stimulating Factors, Erythropoiesis-stimulating agents, Bisphosphonates, Anticoagulation agents, Antiemetics and Glucocorticoids are indeed effective in ameliorating chemotherapy side effects. Meanwhile, it is of great importance that the administration of any of these agents is safe for both mother and fetus. This review aims to provide a précis of the current literature regarding both safety and efficacy of all categories of supportive medication during pregnancy.

Controversies in preoperative bowel preparation in gynecologic and gynecologic oncology surgery: a review of the literature.

PURPOSE: The purpose of this review is to assess the impact of mechanical and oral antibiotics bowel preparation on surgical performance and to investigate their role before gynecologic surgical procedures regarding the infection rates. We also aim to study the updated evidence regarding the use of these different types of bowel preparation, as well as the current preoperative practice applied. METHODS: An extensive search of the literature was conducted with Medline/PubMed, and the Cochrane Library Database of Systematic Reviews being used for our primary search. RESULTS: To date, due to the conflicting guidelines by the scientific societies, surgeons do not use a specific pattern of bowel preparation regimen. There are no strong evidence supporting mechanical bowel preparation, but instead, in many cases, patients' adverse effects, both physiological and psychological have been noted. On the other hand, the combined use of oral antibiotic and mechanical bowel preparation has been proven beneficial in colorectal surgery in reducing postoperative morbidities. CONCLUSION: Based on current literature, in gynecologic surgeries with minimal probability of intraluminal entry, a regimen without any bowel preparation should be applied. The combined administration of both mechanical and oral antibiotic bowel preparation, or even the use of the oral antibiotics alone, should be preserved for cases of increased complexity, where bowel involvement is highly anticipated, such as in gynecologic oncology, as stated in the ERAS protocols. Nonetheless, further research specific to gynecologic surgery is required.

Management of uterine sarcomas and prognostic indicators: real world data from a single-institution.

BACKGROUND: Uterine sarcomas consist a heterogeneous group of mesenchymal gynecological malignancies with unclear therapeutic recommendations and unspecific but poor prognosis, since they usually metastasize and tend to recur very often, even in early stages. METHODS: We retrospectively analyzed all female patients with uterine sarcomas treated in our institution over the last 17 years. Clinico-pathological data, treatments and outcomes were recorded. Kaplan-Meier curves were plotted and time-to-event analyses were estimated using Cox regression. RESULTS: Data were retrieved from 61 women with a median age of 53 (range: 27-78) years, at diagnosis. Fifty-one patients were diagnosed with leiomyosarcoma (LMS), 3 with high grade endometrial stromal sarcoma (ESS), 5 with undifferentiated uterine sarcoma (UUS), 1 with Ewing sarcoma (ES) and 1 with Rhabdomyosarcoma (RS). 24 cases had stage I, 7 stage II, 14 stage III and 16 stage IV disease. Median disease-free survival (DFS) in adjuvant approach was 18.83 months, and median overall survival (OS) 31.07 months. High mitotic count (> 15 mitoses) was significantly associated with worse OS (P < 0.001) and worse DFS (P = 0.028). CONCLUSIONS: Mitotic count appears to be independent prognostic factor while further insights are needed to improve adjuvant and palliative treatment of uterine sarcomas.

Is it the right moment to include hyperthermic intraperitoneal chemotherapy as standard in ovarian cancer management? A reappraisal.

Ovarian cancer is a leading cause of cancer-related death in women and often is diagnosed at an advanced stage with diffuse peritoneal carcinomatosis. Since it is mainly confined to the peritoneal cavity, even after recurrence, it is an ideal target for loco-regional therapy. The standard therapeutic strategy of advanced ovarian cancer is cytoreductive surgery followed by systemic chemotherapy. Intraperitoneal chemotherapy used as adjuvant therapy has shown a survival benefit in ovarian cancer. Hyperthermic intraperitoneal chemotherapy (HIPEC) has several advantages over simple intraperitoneal chemotherapy. This has prompted the use of cytoreductive surgery (CRS) followed by HIPEC in the management of ovarian cancer as a part of first and second line treatment for recurrent disease.

Case Report: Malignant melanoma in a patient with Crohn's disease treated with ustekinumab.

The cornerstone of inflammatory bowel disease (IBD) treatment is immunomodulators. IBD patients are at increased risk of intestinal and extraintestinal malignancy. Ustekinumab is a fully humanized monoclonal anti-IL12/23 antibody with a good safety profile. Malignancies of breast, colon, head and neck, kidney, prostate, thyroid, and non-melanoma skin cancer have been reported among patients who received ustekinumab. We report the case of a 42-year-old Crohn's patient on long-term treatment with ustekinumab, who developed achromatic malignant melanoma. Crohn's was diagnosed at the age of 15, with upper and lower gastrointestinal involvement and was initially treated with azathioprine (2mg/kg for 4 years) and infliximab (5mg/kg for 6 weeks). Due to ileal obstruction, the patient underwent stricturoplasty and received adalimumab (40mg every other week) for two years. He then discontinued therapy and a year later underwent right hemicolectomy. Adalimumab was reinstituted (40mg every other week) and the patient remained in clinical remission for two years. His overall exposure to adalimumab was four years. Ustekinumab was initiated due to a relapse and after 3 years, an incident of scalp itching led to the diagnosis metastatic achromatic malignant melanoma bearing BRAF V600E mutation. He received targeted therapy with an initial good response. We aim to point out the risk of dermatologic malignancy in IBD patients on long-term immunosuppression and the lifelong and meticulous evaluation that is required.

Immunotherapy in HER2-Positive Breast Cancer: A Systematic Review.

Introduction: The clinical outcome of HER2-positive breast cancer patients changed with the use of anti-Her therapies, though it still remains an aggressive and fatal disease. Implementation of immune checkpoint inhibitors in HER2-positive Breast cancer is a concept supported by the reported biological and preclinical data. Methods: We conducted a systematic review of the current literature involving immune checkpoint inhibitors alone or in combination with targeted therapies or chemotherapy finalized or running in HER2-positive breast cancer. Results: Twelve clinical trials and 2 case reports were identified in our study. Conclusion: The reported clinical trials highlight that checkpoint inhibition seems to be promising in metastatic, neoadjuvant, and adjuvant settings of HER2-positive breast cancer.

Oncological Patients With Endocrine Complications After Immunotherapy With Checkpoint Inhibitors Present Longer Progression-Free and Overall Survival.

Aim: The aim of this study was to investigate the association of endocrine complications after ICI immunotherapy with progression-free survival (PFS) and overall survival (OS) in a large single-center oncological cohort. Patients and Methods: In total, 351 patients were included in the analysis, 248 men (70.7%) and 103 women (29.3%). The median age was 66 years. Patients had a variety of cancer types, namely, bladder cancer (131, 37.3%), renal cancer (89, 25.4%), lung cancer (74, 21.1%), ovarian cancer (22, 6.3%), and other types of cancer (35, 10%). The majority (314, 89.4%) were classified as stage IV, while 10.6% (37) were classified as stage III. Most of the patients received immunotherapy with anti-PD1 agents (262, 74.6%) and the rest with anti-PD-L1 agents (89, 25.4%). Kaplan-Meier estimates were used to describe and visualize the effect of categorical variables on OS and PFS. Survival analysis was performed by Kaplan-Meier curves, and survival differences between groups were estimated using the log-rank test. The estimation of the prognostic value of several variables with patients' survival was made by Cox regression models. Results: In total, 68 (19.4%) of patients presented an endocrine complication after immunotherapy with ICIs. Specifically, 66 (18.8%) had thyroid dysfunction, 1 patient presented hypophysitis (0.3%), and 1 patient had a combination of thyroid dysfunction and hypophysitis (0.3%). Patients with an endocrine complication had mPFS of 15 months (95% CI 11.0-18.9 months), while in those without endocrine complication mPFS was 7 months (95% CI 6.1-7.9 months, p < 0.001). Similarly, median OS (mOS) was statistically significant lower in the patients' group without endocrine complication. In fact, mOS was 51 months (95% CI 39.3-62.7 months) for these patients. The presence of endocrine complications after immunotherapy with ICIs retained its significance in terms of longer PFS (HR 0.57, 95% CI 0.39-0.81) and OS (HR 0.53, 95% CI 0.32-0.90) after multivariate analysis. Conclusions: ICI endocrinopathies may be a positive predictor of immunotherapy response.

Pembrolizumab in endometrial cancer: Where we stand now.

Recently, immunotherapy has shown promising results in solid tumors. To the best of our knowledge, this is the first systematic review of published literature synthesizing all the available data and evaluating both the efficacy and safety of pembrolizumab in endometrial cancer. The present study was performed in accordance with the PRISMA guidelines. Eligible articles were identified by searching the MEDLINE and ClinicalTrials.gov databases, using a predefined combination of the terms 'endometrial cancer' and 'pembrolizumab'. Overall, nine articles incorporating data from 712 patients were eligible. Pembrolizumab was demonstrated to be an effective and safe therapeutic option for the management of advanced/metastatic endometrial cancer. Results of ongoing trials evaluating either pembrolizumab alone or in combination with other antineoplastic regimens are expected to confirm its efficacy in this setting of patients. Pembrolizumab appears to be both durable and robust in endometrial cancer. However, there is an emerging need for novel predictive biomarkers to guide clinical practice.

Circulating tumor DNA-based predictive biomarkers in breast cancer clinical trials: a narrative review.

Breast carcinoma is the most frequent and the second leading cause of cancer mortality in women worldwide. Current treatment decisions are based on tumor profiling of the initial tissue biopsy. Cancer though evolves both spatially and temporarily in a significant percentage of patients during treatment. However, sequential biopsies from the primary tumor or its metastatic sites are not either convenient or feasible in the majority of cases. In the era of precision medicine, analysis of circulating blood-based biomarkers in the field of liquid biopsies provides an insight into the dynamic molecular profiling of the primary tumor and its metastases, in a relatively non-invasive way. The latter permits not only patient stratification but also longitudinal evaluation of treatment response, when incorporated into clinical trials. This review summarizes the results from recent and ongoing circulating tumor DNA (ctDNA)-based biomarker-driven clinical trials, with respect to ctDNA analysis' predictive role, both in adjuvant, neo-adjuvant, and metastatic setting. Furthermore, current challenges in ctDNA analysis applications are critically discussed, including pre-analytical and analytical issues, and future perspectives in this field, through the conduct of well-designed, multicenter, randomized, large-scale, biomarker-stratified trials, with robust statistical methods. Despite in its infancy, ctDNA analysis holds great promise as a minimally invasive tool regarding tailored, personalized treatment guidance for breast cancer patients.

Secondary Alopecia Neoplastica Mimicking Alopecia Areata following Breast Cancer.

Cutaneous metastases from visceral carcinomas are relatively uncommon, with an overall incidence ranging from 0.7 to 9%. Diagnosis of scalp metastases usually escapes clinicians and dermatologists due to the fact that these metastases are mimicking other benign dermatological conditions. Herein, we present an uncommon case of scalp alopecia neoplastica mimicking alopecia areata due to breast cancer; a 43-year-old woman diagnosed with lobular cancer 3 years previously presented with acute loss of hair in well-circumscribed areas of the scalp and was diagnosed with alopecia areata by a private-practice dermatologist. She was then reevaluated, and due to her history of breast cancer, a biopsy from the scalp was performed and revealed alopecia neoplastica. At the same time that the skin lesions were recognized as disease involvement, the patient presented with dyspepsia, and endoscopy of the upper and lower gastrointestinal tract also revealed metastasis to the stomach and bowel. Gastrointestinal metastasis may occur with several types of cancer, but the stomach and bowel are rare metastatic sites for breast cancer.

JQ1 inhibits tumour growth in combination with cisplatin and suppresses JAK/STAT signalling pathway in ovarian cancer.

BACKGROUND: Overexpression of c-Myc is commonly seen in human ovarian cancers, and this could be a potentially novel therapeutic target for this disease. JQ1, a selective small-molecule BET (Bromodomain and extraterminal domain family) bromodomain (BRDs) inhibitor, has been found to suppress tumour progression in several cancer cell types. RESULTS: Using a panel of ovarian cancer cell lines and primary cell cultures from human ovarian cancer ascites, we demonstrated that JQ1 significantly suppressed cell proliferation and induced apoptosis in an ovarian cancer cell by targeting BRD4 and c-Μyc. In addition, JQ1 sensitized ovarian cancer cells to cisplatin, the most commonly used chemotherapeutic agent in ovarian cancer. Importantly, this effect was observed in ovarian cells, which exhibited resistance to cisplatin alone. Finally, we show that JQ1 interacts with the JAK-STAT signalling pathway, a pathway important in supporting ovarian cancer cell survival by suppressing or inducing genes involved in cell survival and apoptosis, respectively. CONCLUSION: Our data, taken together, suggest that JQ1 is an attractive antitumour candidate for further investigation in the treatment of ovarian cancer, as it associates with cell proliferation, apoptosis, and alterations in the JAK-STAT signalling pathway, especially in patients with a platinum-resistant profile or in patients with relapsed disease.

Observational Study of Clinical Practice in Patients with Pancreatic Adenocarcinoma in Greece.

BACKGROUND: During the last decade, significant improvement was made in systemic therapy of pancreatic adenocarcinoma (PAC). The impact of this progress in everyday clinical practice has not been fully described yet. The aim of the study was to investigate the pattern followed by Greek Medical Oncologists regarding the treatment of patients with PAC. METHODS: This observational, noninterventional multicenter study recorded clinical data from the files of 200 active patients (alive and under treatment or follow-up) for a two-year period (November 2015 until November 2017) from 20 oncology centers around Greece. RESULTS: In total, 51 (25.5%) patients underwent radical surgical resection of PAC, and 40 (78.4%) of them received adjuvant and 1 (2.0%) neoadjuvant chemotherapy. The median time to recurrence was 7.9 months, and median overall survival (OS), 20.2 months. First-line chemotherapy was administered to 193 (96.5%) patients. The majority of patients were treated with the combination of nab-paclitaxel-gemcitabine (NPG), 5-fluorouracil, leucovorin, irinotecan, oxaliplatin (FOLFIRINOX), or gemcitabine monotherapy. Of them, 39.5% responded to the treatment. Median OS and PFS were 14.1 months and 7.0 months, respectively. Second-line treatment was administered to 112 patients. The majority received NPG, FOLFIRINOX/capecitabine, oxaliplatin, irinotecan (CAPOXIRI), or 5-fluorouracil, leucovorin, oxaliplatin (FOLFOX)/capecitabine, oxaliplatin (CAPOX). Median OS with second-line treatment was 8.6 months, and median PFS, 5.5 months. The most common chemotherapy sequences were NPG as first-line followed by FOLFIRINOX/CAPOXIRI as second-line, NPG followed by FOLFOX/CAPOX, NPG followed by other regimens, and FOLFIRINOX/CAPOXIRI followed by NPG. CONCLUSION: This study described the significant improvement in prognosis of PAC patients receiving palliative chemotherapy and the relatively high rate of receipt of second-line chemotherapy, according to real-world data. However, due to the nonrandomized nature of the study, any comparison between different chemotherapy regimens should be regarded with caution.

Panitumumab in combination with modified docetaxel/cisplatin/5-fluorouracil as first-line treatment in gastric and gastroesophageal junction adenocarcinomas: a multicenter phase II study by the Hellenic Oncology Research Group.

BACKGROUND: A phase I/II study to define the maximum tolerated dose (MTD) of biweekly docetaxel/cisplatin/5-fluorouracil (DCF) plus panitumumab (P), its efficacy, and tolerability as first-line treatment in advanced gastroesophageal cancer. METHODS: In phase I part, patients with unresectable locally advanced or metastatic adenocarcinomas of the stomach or the gastroesophageal junction received cisplatin (40 mg/m2 on day 1), leucovorin (400 mg/m2 on day 1), 5-fluorouracil (400 mg/m2 bolus on day 1), 5-fluorouracil (1000 mg/m2/daycontinuous infusion on days 1-2), and escalated doses of docetaxel (on day 1) plus P (6 mg/kg on day 1) every 2 weeks. In phase II part, patients were treated with DCF/P at the MTD and the primary endpoint was response rate. The expected response rate was set at >40%. RESULTS: The MTD for docetaxel in the mDCF/P was defined at 40 mg/m2 and a total of 40 evaluable patients were enrolled in phase II study. One (2.5%) complete and 13 (32.5%) partial responses (overall response rate: 35%), as well as 16 (40%) disease stabilizations were documented. The median progression-free survival was 6.9 months (95% confidence interval [CI] 3.5-10.3) and the median overall survival was 11.3 months (95%CI 7.7-14.8). Grade 3-4 neutropenia occurred in 10 patients (25%) and febrile neutropenia in 2 (5%). Allergic reactions (grade 1-4) occurred in 9 patients (22.5%). There was 1 treatment-related death. CONCLUSIONS: mDCF/P combination was feasible, though associated with a poor toxicity profile. However, the study failed to meet its primary endpoint and was terminated prematurely due to futility.
