Alternative dosing regimen of exemestane in a randomized presurgical trial: the role of obesity in biomarker modulation.

In a 3-arm presurgical trial, four-six weeks exemestane 25 mg three times/week (TIW) was non-inferior to 25 mg/day (QD) in suppressing circulating estradiol in postmenopausal women with ER-positive breast cancer. Since obesity may decrease exemestane efficacy, we analyzed changes in sex steroids, adipokines, Ki-67, and drug levels in relation to obesity. Postmenopausal women with early-stage ER-positive breast cancer were randomized to either exemestane 25 mg QD (n = 57), 25 mg TIW (n = 57), or 25 mg/week (QW, n = 62) for 4-6 weeks before breast surgery. Serum and tissue pre- and post-treatment biomarkers were stratified by body mass index (BMI)< or ≥30 kg/m2. Post-treatment median exemestane and 17-OH exemestane levels were 5-6 times higher in the QD arm compared to the TIW arm. For obese women, TIW maintained comparable reductions to QD in systemic estradiol levels, although the reduction in estrone was less with the TIW regimen. There was less suppression of SHBG with the TIW versus the QD dose schedule in obese women which should result in less systemic bioavailable estrogens. Metabolically, the effect of the TIW regimen was similar to the QD regimen for obese women in terms of leptin suppression and increase in the adiponectin-leptin ratio. Reduction in tissue Ki-67 was less for obese women on the TIW regimen than QD, although changes were similar for non-obese women. Our findings suggest that TIW exemestane should be explored further for primary cancer prevention in both normal weight and obese cohorts.

Effect of metformin and lifestyle intervention on adipokines and hormones in breast cancer survivors: a pooled analysis from two randomized controlled trials.

PURPOSE: We investigated the effect of metformin and lifestyle intervention on metabolic, inflammatory, and steroid biomarkers of breast cancer (BC) recurrence risk in two intervention trials among BC survivors with overweight or obesity. METHODS: Baseline and follow-up serum samples collected during the two trials were analyzed and data pooled. The USA trial (Reach for Health) included postmenopausal BC survivors (n = 333) randomly assigned to 6-month metformin vs placebo and lifestyle intervention (LSI) vs control (2 × 2 factorial design). The Italian trial (MetBreCS) included BC survivors (n = 40) randomized to 12-month metformin vs placebo. Insulin resistance (HOMA-IR), adipokines, cytokines, and steroids were measured. RESULTS: Metformin compared to placebo showed a favorable decrease in leptin (- 8.8 vs - 3.5 ng/mL; p < 0.01) and HOMA-IR (- 0.48 vs - 0.25; p = 0.03), and an increase in SHBG (2.80 vs 1.45 nmol/L; p < 0.01). Excluding women taking aromatase inhibitors, metformin (n = 84) compared to placebo (n = 99) decreased estradiol (- 4 vs 0 pmol/L; p < 0.01), estrone (- 8 vs 2 pmol/L; p < 0.01) and testosterone (- 0.1 vs 0 nmol/L-; p = 0.02). LSI favorably affected adiponectin (0.45 vs - 0.06 ug/mL; p < 0.01), leptin (- 10.5 vs - 4.4 ng/mL; p < 0.01), HOMA-IR (- 0.6 vs 0.2; p = 0.03), and SHBG (2.7 vs 1.1 nMol/L; p = 0.04) compared to controls. The strongest impact was observed combining metformin with LSI on adipokines, CRP, SHBG, and estrogens. CONCLUSIONS: Supportive healthy lifestyle programs combined with metformin to achieve maximal risk reduction among BC cancer survivors are recommended, especially for those with obesity in menopause.

Novel Treatments for Obesity: Implications for Cancer Prevention and Treatment.

It is now established that obesity is related to a higher incidence of cancer during a lifespan. The effective treatment of obesity opens up new perspectives in the treatment of a relevant modifiable cancer risk factor. The present narrative review summarizes the correlations between weight loss in obesity and cancer. The current knowledge between obesity treatment and cancer was explored, highlighting the greatest potential for its use in the treatment of cancer in the clinical setting. Evidence for the effects of obesity therapy on proliferation, apoptosis, and response to chemotherapy is summarized. While more studies, including large, long-term clinical trials, are needed to adequately evaluate the relationship and durability between anti-obesity treatment and cancer, collaboration between oncologists and obesity treatment experts is increasingly important.

Inflammatory and Metabolic Biomarker Assessment in a Randomized Presurgical Trial of Curcumin and Anthocyanin Supplements in Patients with Colorectal Adenomas.

Colorectal cancer prevention is crucial for public health, given its high mortality rates, particularly in young adults. The early detection and treatment of precancerous lesions is key to preventing carcinogenesis progression. Natural compounds like curcumin and anthocyanins show promise in impeding adenomatous polyp progression in preclinical models. We conducted a randomized, double-blind, placebo-controlled, phase II presurgical trial in 35 patients with adenomatous polyps to explore the biological effects of curcumin and anthocyanins on circulating biomarkers of inflammation and metabolism. No significant difference in biomarker changes by treatment arm was observed. However, the network analysis before treatment revealed inverse correlations between adiponectin and BMI and glycemia, as well as direct links between inflammatory biomarkers and leptin and BMI. In addition, a considerable inverse relationship between adiponectin and grade of dysplasia was detected after treatment (corr = -0.45). Finally, a significant increase in IL-6 at the end of treatment in subjects with high-grade dysplasia was also observed (p = 0.02). The combined treatment of anthocyanins and curcumin did not result in the direct modulation of circulating biomarkers of inflammation and metabolism, but revealed a complex modulation of inflammatory and metabolic biomarkers of colon carcinogenesis.

Diagnostic effectiveness of [18F]Fluoroestradiol PET/CT in oestrogen receptor-positive breast cancer: the key role of histopathology. Evidence from an international multicentre prospective study.

INTRODUCTION: [18F]Fluoroestradiol ([18F]FES) PET/CT has been proposed as a tool for detecting the oestrogen receptor density in patients with metastatic breast cancer (BC) non-invasively across all disease localizations. However, its diagnostic potential in terms of the detection rate (DR) of metastases is unclear. In this study, we pitted this method against [18F]FDG PET/CT and tried to identify predictors of the diagnostic superiority of the [18F] FES-based method. MATERIALS AND METHODS: From a multicentre database, we enrolled all patients with metastatic BC who had undergone both [18F]FES PET/CT and [18F]FDG PET/CT. Two readers assessed both images independently and used a patient-based (PBA) and lesion-based analysis (LBA) to calculate the DR. Pathology-related and clinical factors were tested as predictors of [18F]FES PET/CT superiority using a multivariate model. RESULTS: 92 patients, bearing a total of 2678 metastases, were enrolled. On PBA, the DR of [18F]FDG and [18F]FES PET/CT was 97% and 86%, respectively (p = 0.018). On LBA, the [18F]FES method proved more sensitive than [18F]FDG PET/CT in lymph nodes, bone, lung and soft tissue (p < 0.01). This greater sensitivity was associated with lobular histology, both on PBA (Odds Ratio (OR) 3.4, 95%CI 1.0-12.3) and on LBA (OR 4.4, 95%CI 1.2-16.1 for lymph node metastases and OR 3.29, 95%CI 1.1-10.2 for bone localizations). CONCLUSIONS: The overall DR of [18F]FES PET/CT appears to be lower than that of [18F]FDG PET/CT on PBA. However, the [18F]FES method, if positive, can identify more lesions than [18F]FDG at most sites. The higher sensitivity of [18F]FES PET/CT was associated with lobular histology.

Randomized Placebo Controlled Trial of Low-Dose Tamoxifen to Prevent Recurrence in Breast Noninvasive Neoplasia: A 10-Year Follow-Up of TAM-01 Study.

PURPOSE: Five-year data of the phase III trial TAM-01 showed that low-dose tamoxifen at 5 mg once daily administered for 3 years in women with intraepithelial neoplasia (IEN) reduced by 52% the recurrence of invasive breast cancer or ductal carcinoma in situ (DCIS), without additional adverse events over placebo. Here, we present the 10-year results. METHODS: We randomly assigned 500 women with breast IEN (atypical ductal hyperplasia, lobular carcinoma in situ [LCIS], or hormone-sensitive or unknown DCIS) to low-dose tamoxifen or placebo after surgery with or without irradiation. The primary end point was the incidence of invasive breast cancer or DCIS. RESULTS: The TAM-01 population included 500 women (20% atypical ductal hyperplasia, 11% LCIS, and 69% DCIS). The mean (±SD) age at the start of treatment was 54 ± 9 years, and 58% of participants were postmenopausal. After a median follow-up of 9.7 years (IQR, 8.3-10.9 years), 66 breast cancers (15 in situ; 51 invasive) were diagnosed: 25 in the tamoxifen group and 41 in the placebo group (annual rate per 1,000 person-years, 11.3 with tamoxifen v 19.5 with placebo; hazard ratio [HR], 0.58; 95% CI, 0.35 to 0.95; log-rank P = .03). Most recurrences were invasive (77%) and ipsilateral (59%). Regarding contralateral breast cancer incidence, there were six events in the tamoxifen arm and 16 in the placebo arm (HR, 0.36; 95% CI, 0.14 to 0.92; P = .025). The number needed to be treated to prevent one case of breast event with tamoxifen therapy was 22 in 5 years and 14 in 10 years. The benefit was seen across all patient subgroups. There was a significant 50% reduction of recurrence with tamoxifen in the DCIS cohort, which represents 70% of the overall population (HR, 0.50; 95% CI, 0.28 to 0.91; P = .02). No between-group difference in the incidence of serious adverse events was reported during the prolonged follow-up period. CONCLUSION: Tamoxifen 5 mg once daily for 3 years significantly prevents recurrence from noninvasive breast cancer after 7 years from treatment cessation without long-term adverse events.

Efficacy of Alternative Dose Regimens of Exemestane in Postmenopausal Women With Stage 0 to II Estrogen Receptor-Positive Breast Cancer: A Randomized Clinical Trial.

Importance: Successful therapeutic cancer prevention requires definition of the minimal effective dose. Aromatase inhibitors decrease breast cancer incidence in high-risk women, but use in prevention and compliance in adjuvant settings are hampered by adverse events. Objective: To compare the noninferiority percentage change of estradiol in postmenopausal women with estrogen receptor-positive breast cancer given exemestane, 25 mg, 3 times weekly or once weekly vs a standard daily dose with a noninferiority margin of -6%. Design, Setting, and Participants: This multicenter, presurgical, double-blind phase 2b randomized clinical trial evaluated 2 alternative dosing schedules of exemestane. Postmenopausal women with estrogen receptor-positive breast cancer who were candidates for breast surgery were screened from February 1, 2017, to August 31, 2019. Blood samples were collected at baseline and final visit; tissue biomarker changes were assessed from diagnostic biopsy and surgical specimen. Biomarkers were measured in different laboratories between April 2020 and December 2021. Interventions: Exemestane, 25 mg, once daily, 3 times weekly, or once weekly for 4 to 6 weeks before surgery. Main Outcomes and Measures: Serum estradiol concentrations were measured by solid-phase extraction followed by liquid chromatography-tandem mass spectrometry detection. Toxic effects were evaluated using the National Cancer Institute terminology criteria, and Ki-67 was assessed by immunohistochemistry. Results: A total of 180 women were randomized into 1 of the 3 arms; median (IQR) age was 66 (60-71) years, 63 (60-69) years, and 65 (61-70) years in the once-daily, 3-times-weekly, and once-weekly arms, respectively. In the intention-to-treat population (n = 171), the least square mean percentage change of serum estradiol was -89%, -85%, and -60% for exemestane once daily (n = 55), 3 times weekly (n = 56), and once weekly (n = 60), respectively. The difference in estradiol percentage change between the once-daily and 3-times-weekly arms was -3.6% (P for noninferiority = .37), whereas in compliant participants (n = 153), it was 2.0% (97.5% lower confidence limit, -5.6%; P for noninferiority = .02). Among secondary end points, Ki-67 and progesterone receptor were reduced in all arms, with median absolute percentage changes of -7.5%, -5.0%, and -4.0% for Ki-67 in the once-daily, 3-times-weekly, and once-weekly arms, respectively (once daily vs 3 times weekly, P = .31; once daily vs once weekly, P = .06), and -17.0%, -9.0%, and -7.0% for progesterone receptor, respectively. Sex hormone-binding globulin and high-density lipoprotein cholesterol had a better profile among participants in the 3-times-weekly arm compared with once-daily arm. Adverse events were similar in all arms. Conclusions and Relevance: In this randomized clinical trial, exemestane, 25 mg, given 3 times weekly in compliant patients was noninferior to the once-daily dosage in decreasing serum estradiol. This new schedule should be further studied in prevention studies and in women who do not tolerate the daily dose in the adjuvant setting.

Taste and Smell Disorders in Cancer Treatment: Results from an Integrative Rapid Systematic Review.

Taste and smell disorders (TSDs) are common side effects in patients undergoing cancer treatments. Knowing which treatments specifically cause them is crucial to improve patients' quality of life. This review looked at the oncological treatments that cause taste and smell alterations and their time of onset. We performed an integrative rapid review. The PubMed, PROSPERO, and Web of Science databases were searched in November 2022. The article screening and study selection were conducted independently by two reviewers. Data were analyzed narratively. Fourteen studies met the inclusion criteria and were included. A high heterogeneity was detected. Taste disorders ranged between 17 and 86%, while dysosmia ranged between 8 and 45%. Docetaxel, paclitaxel, nab-paclitaxel, capecitabine, cyclophosphamide, epirubicin, anthracyclines, and oral 5-FU analogues were found to be the drugs most frequently associated with TSDs. This review identifies the cancer treatments that mainly lead to taste and smell changes and provides evidence for wider studies, including those focusing on prevention. Further studies are warranted to make conclusive indication possible.

Effect of sex on psychological distress and fatigue over time in a prospective cohort of cancer survivors.

BACKGROUND: Studies indicate a higher level of distress in women than men with cancer, but whether this difference is retained over time is unknown. We studied the frequency and level of distress and fatigue during time according to gender in a cohort of cancer survivors. PATIENTS AND METHODS: In this prospective study, cancer survivors were invited to undergo a psychological session immediately before the medical visit. Distress was assessed by the distress thermometer, and fatigue was assessed by the ESAS-r scale. Patients underwent follow-up visits to assess changes over time. RESULTS: A total of 305 patients and 568 visits were performed with a median follow-up of 15.8 months. At baseline, females, young age, and breast cancer patients had significantly higher distress. However, there was an increase in distress of 0.29 points every 6 months in males (95% CI, 0.09-0.50) versus no change in females (0.03 points, 95% CI, - 0.09-0.15; p-interaction = 0.01). The different behavior of cancer distress during time according to gender was more evident in subjects aged 68 or older due to increasing physical problems in men (p-interaction = 0.005). There was no change in fatigue with time according to sex. CONCLUSIONS: Women, younger age, and breast cancer patients had increased cancer distress at the initial visit. However, women tend to stabilize during follow-up, whereas men tend to worsen their distress, especially because of physical and emotional problems, suggesting different coping capabilities. TRIAL REGISTRATION: The study is registered at ClinicalTrials.gov NCT05122052. IMPLICATIONS FOR CANCER SURVIVORS: Interventions aimed at improving recognition of emotions related to disease experience in male cancer survivors appear necessary.

NK Cell-Based Immunotherapy in Colorectal Cancer.

Human Natural Killer (NK) cells are all round players in immunity thanks to their powerful and immediate response against transformed cells and the ability to modulate the subsequent adaptive immune response. The potential of immunotherapies based on NK cell involvement has been initially revealed in the hematological setting but has inspired the design of different immune tools to also be applied against solid tumors, including colorectal cancer (CRC). Indeed, despite cancer prevention screening plans, surgery, and chemotherapy strategies, CRC is one of the most widespread cancers and with the highest mortality rate. Therefore, further efficient and complementary immune-based therapies are in urgent need. In this review, we gathered the most recent advances in NK cell-based immunotherapies aimed at fighting CRC, in particular, the use of monoclonal antibodies targeting tumor-associated antigens (TAAs), immune checkpoint blockade, and adoptive NK cell therapy, including NK cells modified with chimeric antigen receptor (CAR-NK).

Randomized phase II trial of weekly paclitaxel vs. cediranib-olaparib (continuous or intermittent schedule) in platinum-resistant high-grade epithelial ovarian cancer.

BACKGROUND: Previous findings showed that cediranib-olaparib increased PFS in women with recurrent platinum-sensitive ovarian cancer compared to olaparib alone. METHODS: BAROCCO trial randomized 123 patients: 80mg/m2 paclitaxel weekly up to 24 weeks (control), olaparib 300mg tablets twice daily together with 20mg cediranib daily (continuous schedule) or with 20mg cediranib 5 days/week (intermittent schedule) until progression. The primary objective was the PFS comparison between each experimental arm and the control (alpha one-sided 5%; power 80%; HR 0.5). RESULTS: The median platinum-free interval was 1.9 months, 60% of patients had been pretreated with 3 or more chemotherapy lines. Median PFS for paclitaxel, the continuous, and the intermittent schedules were 3.1, 5.6, and 3.8 months. The HR for PFS in the continuous arm vs control was 0.76 (90% CI: 0.50-1.14, p = 0.265). The HR for PFS in the intermittent arm vs control was 1.03 (90% CI: 0.68-1.55, p = 0.904). Treatment was discontinued due to adverse events in 15%, 20%, and 5% of patients in the control, continuous and intermittent arms. Grade ≥ 3 anemia and diarrhea and hypertension of any grade occurred only in the experimental arms, and peripheral neuropathies and alopecia only in the control arm. Five serious adverse drug reactions occurred and two were fatal: one in the control and one in the continuous arm. CONCLUSIONS: The combination of cediranib-olaparib was not superior to chemotherapy in terms of PFS in heavily pretreated platinum-resistant ovarian cancer patients. However, this oral doublet, is active and may offer a non-chemotherapy option in this difficult to treat population.

Case report: Variable response to immunotherapy in ovarian cancer: Our experience within the current state of the art.

Despite recent advances in ovarian cancer (OC) treatment, including the introduction of bevacizumab and PARP-inhibitors, OC remains a lethal disease. Other therapeutic options are being explored, such as immunotherapy (IT), which has been proved effective in many solid tumors. Findings about tumor-infiltrating cytotoxic and regulatory T cells, together with the expression of PD-1 on immune cells and of PD-L1 on tumor cells, gave the rationale for an attempt to the use of IT also in OC. We treated two patients with avelumab, an anti-PD-L1 monoclonal antibody, after the first line of chemotherapy: Patient A underwent 19 cycles of maintenance therapy with avelumab with a disease-free interval of 12 months, whereas patient B showed a slight progression of disease after only eight cycles. A higher PD-L1 expression in tumor cells of patient A was detected. She also underwent a genomic assessment that described the presence of a high Tumor Mutational Burden (TMB) and a status of Loss of Heterozygosity (LoH). This different response to the same treatment puts in evidence that some genomic and immune features might be investigated.

Predictors of poor seroconversion and adverse events to SARS-CoV-2 mRNA BNT162b2 vaccine in cancer patients on active treatment.

PURPOSE: Initial findings in patients with cancer suggest a lower seroconversion to SARS-CoV-2 vaccination possibly related to myelo-immunosuppressive therapies. We conducted a prospective study to assess factors predicting poor seroconversion and adverse events following immunisation (AEFI) to the BNT162b2 vaccine in patients on active treatment. PATIENTS AND METHODS: Cancer patients, candidates to two doses of BNT162b2 SARS-CoV-2 vaccination, were enrolled. Patients on active surveillance served as controls. The primary endpoint was poor seroconversion (anti S1/S2 IgG < 25 AU/mL) after 21 days from the second dose. RESULTS: Between March and July 2021, 320 subjects were recruited, and 291 were assessable. The lack of seroconversion at 21 days from the second dose was 1.6% (95% CI, 0.4-8.7) on active surveillance, 13.9% (8.2-21.6) on chemotherapy, 11.4% (5.1-21.3) on hormone therapy, 21.7% (7.5-43.7) on targeted therapy and 4.8% (0.12-23.8) on immune-checkpoint-inhibitors (ICI). Compared to controls, the risk of no IgG response was greater for chemotherapy (p = 0.033), targeted therapy (0.005) and hormonotherapy (p = 0.051). Lymphocyte count < 1 × 109/L (p = 0.04) and older age (p = 0.03) also significantly predicted poor seroconversion. Overall, 43 patients (14.8%) complained of AEFI, mostly of mild grade. Risk of AEFI was greater in females (p = 0.001) and younger patients (p = 0.009). CONCLUSION: Chemotherapy, targeted therapy, hormone therapy, lymphocyte count < 1 × 109/L, and increasing age predict poor seroconversion after two doses of BNT162b2 in up to 20% of patients, indicating the need for a third dose and long-term serological testing in non-responders. AEFI occur much more frequently in women and younger subjects who may benefit from preventive medications. CLINICALTRIALS. GOV IDENTIFIER: NCT04932863.

A Presurgical Study of Curcumin Combined with Anthocyanin Supplements in Patients with Colorectal Adenomatous Polyps.

Adenomatous polyps are precancerous lesions associated with a higher risk of colorectal cancer (CRC). Curcumin and anthocyanins have shown promising CRC-preventive activity in preclinical and epidemiological studies. The objective of this window-of-opportunity, proof-of principle trial was to evaluate the effect of curcumin combined with anthocyanin supplements on tissue biomarkers of colorectal adenomatous polyps. Eligible patients received either anthocyanin and curcumin supplementation or related matching placebo for 4-6 weeks before polyp removal. Adenomatous polyps and adjacent tissue biopsies were collected at baseline and after supplementation for immunohistochemical assessment of ß-catenin, NF-kappa B (NF-κB), Ki-67, P53, and dysplasia. No differences were observed in baseline biomarker expression between normal and dysplastic tissues. The combination of anthocyanins and curcumin resulted in a significant borderline reduction of NF-κB immunohistochemistry (IHC) expression in adenoma tissue (geometric mean ratio (GMR): 0.72; 95% confidence interval (CI): 0.51-1.00; p-value: 0.05) and a trend to a reduction of Ki-67 (GMR: 0.73; 95% CI: 0.50-1.08; p-value: 0.11). No significant modulation of biomarkers in normal adjacent mucosa was observed. We concluded that the combined supplementation of anthocyanins and curcumin seems to lead to a potentially favorable modulation of tissue biomarkers of inflammation and proliferation in colon adenomas.

Home Se-Cure: A Home Care Service for Cancer Patients during the COVID-19 Pandemic.

Cancer patients are exposed to a greater risk of COVID-19 infection, resulting in treatment delays and unnecessary hospitalizations. International authorities have suggested reducing visits to hospitals and guarantee continuity of care. We developed a home care project called Home Se-Cure (HSC) to guarantee the continuity of oral, intramuscular, and subcutaneous cancer therapy during COVID-19. The Home Se-Cure project included cancer patients living near Galliera Hospital. Patients received home visits by registered nurses (RNs), whoperformed blood tests and delivered cancer therapies. Patients were instructed to take drugs after blood test results and therapy confirmation by oncologists. Sixty-six patients decided to participate and 38 declined the service. A customer satisfaction questionnaire was administered to a subgroup of patients participating in the project. The most prevalent disease in the HSC group was prostate cancer. The mean age of the patients in HSC was 78.4 years and 68.9 in the decliner group. The majority of the HSC participants appreciated the project because they could stay at home (71%) and reduce the risk of COVID-19 contagion (67.7%). Compared to decliners, the time the study group saved was 2033 hours. HSC guaranteed the continuity of care during the COVID-19 pandemic by reducing the number of patients in the hospital and avoiding crowds in the waiting room.

Patient- versus physician-reported outcomes in a low-dose tamoxifen trial in noninvasive breast cancer.

BACKGROUND: We recently conducted a de-escalation trial of low-dose tamoxifen 5 mg/day ("babytam", BT) or placebo given for 3 years in 500 women with noninvasive breast cancer. Women on babytam had a 52% reduction of recurrence (invasive breast cancer or DCIS) after 5 years. Since menopausal symptoms are major reasons for treatment withdrawal during tamoxifen preventive therapy, we compared and analyzed the patient-reported outcomes (PROs) with the physician-reported adverse events and studied their association with recurrence. METHODS: Menopausal symptoms recorded by physicians using the Common Terminology Criteria (CTCAEs) were compared with a patient self-reported validated questionnaire reviewed by a research nurse at baseline and every 6 months up to 36 months. Hot flashes (HF), the main outcome measure, were detected through a self-report 7-day diary for frequency and intensity. Treatment adherence and efficacy were assessed by the Kaplan-Meier curves and the Cox model. RESULTS: The number of HF events at 12, 24, and 36 months for PROs versus CTCAEs was 246 versus 12, 238 versus 8, and 210 versus 4, respectively. The majority of events were grade 1. There was no difference in PROs between babytam and placebo except for HF daily frequency, which increased by 1.5 events (95% CI, 1.1-1.8) on placebo to 2.1 on babytam (95% CI, 1.7-2.5, p = 0.05). The presence of HF at baseline was a favorable prognostic factor for recurrence and a predictive factor for response to babytam. Adherence was similar between babytam and placebo. CONCLUSIONS: The use of PROs is effective for identifying frequent mild grade menopausal symptoms which are underestimated by physicians but important prognostic and predictive factors. Research nurse can use these results as a tool to reassure patients about symptoms, improve adherence to treatment, and limit dropouts.

Percutaneous trans-hepatic rescue and neo-creation of a post-surgical complete hepaticojejunostomy dehiscence.

Biliary leakage complicating hepaticojejunostomy is a therapeutic dilemma for surgeons, gastroenterologist, and interventional radiologist. It is a major cause of postoperative morbidity. Percutaneous biliary intervention techniques have been developed for treating benign post-surgical biliary disease in patients not having severely compromised clinical conditions. Interventional radiology manoeuvres are especially indicated as the first line of treatment if endoscopic procedures are unfeasible for patients due to postsurgical anatomical modifications. We present a case of post-surgical complete hepaticojejunostomy dehiscence that was treated totally by percutaneous techniques with trans-hepatic rescue and hepaticojejunostomy neo-creation.

To Enhance or Not to Enhance? The Role of Contrast Medium 18F-FDG PET/CT in Recurrent Ovarian Carcinomas.

Background and Objectives: 18F-fluorodeoxyglucose (FDG) positron emission tomography/X-ray computed tomography (PET/CT) represents the mainstay diagnostic procedure for suspected ovarian cancer (OC) recurrence. PET/CT can be integrated with contrast medium and in various diagnostic settings; however, the effective benefit of this procedure is still debated. We aimed to compare the diagnostic capabilities of low-dose and contrast-enhanced PET/CT (PET/ldCT and PET/ceCT) in patients with suspected ovarian cancer relapse. Materials and Methods: 122 OC patients underwent both PET/ldCT and PET/ceCT. Two groups of nuclear medicine physicians and radiologists scored the findings as positive or negative. Clinical/radiological follow-up was used as ground truth. Sensitivity, specificity, negative/positive predictive value, and accuracy were calculated at the patient and the lesion level. Results: A total of 455 and 474 lesions were identified at PET/ldCT and PET/ceCT, respectively. At the lesion level, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were not significantly different between PET/ldCT and PET/ceCT (98%, 93.3%, 97.4%, 94.9%, and 96.9% for PET/ldCT; 99%, 95.5%, 98.3%, 97%, and 98% for PET/ceCT, p = ns). At the patient level, no significant differences in these parameters were identified (e.g., p = 0.22 and p = 0.35 for accuracy, in the peritoneum and lymph nodes, respectively). Smaller peritoneal/lymph node lesions close to physiological FDG uptake sources were found in the cases of misidentification by PET/ldCT. PET/ceCT prompted a change in clinical management in four cases (3.2%) compared to PET/ldCT. Conclusions: PET/ceCT does not perform better than PET/ldCT but can occasionally clarify doubtful peritoneal findings on PET/ldCT. To avoid unnecessary dose to the patient, PET/ceCT should be excluded in selected cases.
