- Abstract
Introduction: Mechanical bowel obstruction is a frequent acute and life-threatening event in relapsed ovarian cancer. Salvage surgery after failure of all conservative approaches, resulting in short bowel syndrome (SBS) constitutes a therapeutic dilemma. Our aim was to evaluate patients' surgical and clinical outcome in these highly palliative situations. Previous, limited, data reported a high morbidity and mortality. However, recent surgical and therapeutical improvements in relapsed ovarian cancer (ROC) offer better identification of patients who might benefit from surgery in an effort to extend the window of opportunity to subsequently offer these patients novel systemic therapeutic approaches. Material and methods: All subsequent ROC patients between 2012 and 2017 with acute mechanical bowel obstruction who underwent salvage extraperitoneal en bloc intestinal resection were retrospectively identified. Data were collected from two ESGO certified Ovarian Cancer Centers of Excellence (Charité Berlin and Imperial College London) and systematically evaluated regarding surgical and clinical outcomes. Results: Overall, 87 ROC patients were included in the analysis (median age 56 years, range 24–88), 47% were platinum resistant. High grade serous was the most common histology (76%) while most of the patients (67%) had at least two previous lines of treatment. Mean observed OS was 7.8 months. After salvage surgery, 46% of the patients had a residual small bowel length < 180 cm and 18% > 180 cm resulting in 41% in need of total parental nutrition. In 80% of the patients a permanent stoma was necessary. 30d morbidity and mortality was 74% and 10%, respectively. More than half of the patients were able to receive further courses of chemotherapy after surgery. Discussion: Salvage surgery for bowel obstruction in ROC patients needs careful consideration and identification of optimal surgical candidates to have the maximal therapeutic benefit. Despite the challenging morbidity profile, most patients managed to proceed to subsequent novel and conventional systemic treatment and so have their window of therapeutic opportunity extended.

Background: An effective cross-cultural doctor-patient communication is vital for health literacy and patient compliance. Building a good relationship with medical staff is also relevant for the treatment decision-making process for cancer patients. Studies about the role of a specific migrant background regarding patient preferences and expectations are lacking. We therefore conducted a multicentre prospective survey to explore the needs and preferences of patients with a migrant background (PMB) suffering from gynecological malignancies and breast cancer to evaluate the quality of doctor-patient communication and cancer management compared to non-migrants (NM).Methods: This multicentre survey recruited patients with primary or recurrence of breast, ovarian, peritoneal, or fallopian tube cancer. The patients either filled out a paper form, participated via an online survey, or were interviewed by trained staff. A 58-item questionnaire was primarily developed in German and then translated into three different languages to reach non-German-speaking patients.Results: A total of 606 patients were included in the study: 54.1% (328) were interviewed directly, 9.1% (55) participated via an online survey, and 36.8% (223) used the paper print version. More than one quarter, 27.4% (166) of the participants, had a migrant background. The majority of migrants and NM were highly satisfied with the communication with their doctors. First-generation migrants (FGM) and patients with breast cancer were less often informed about participation in clinical trials (p < 0.05) and 24.5% of them suggested the help of an interpreter to improve the medical consultation. Second and third-generation migrants (SGM and TGM) experienced more fatigue and nausea than expected.Conclusions: Our results allow the hypothesis that training medical staff in intercultural competence and using disease-related patient information in different languages can improve best supportive care management and quality of life in cancer patients with migrant status.

Background: Aim of this study was to analyze the impact of pain on quality of life and survival in recurrent OC patients.Methods: Raw data including the QLQ-C30 questionnaire from three phase II/III trials ("Topotecan phase III," "Hector," and "TRIAS") conducted by the North-Eastern German Society of Gynecological Oncology (NOGGO) were synthesized and analyzed using logistic and Cox regression analyses.Results: Data on pain was available for 952 patients out of 1226. Moderate to severe pain, which was defined as pain ≥ 50 in the QLQ-C30 symptom scale, was experienced by more than one-third of patients (36.6%). A total of 31% were taking non-opioid pain medication and 16% opioids. Median age at randomization was 61 years (range 25-84). Most patients (84.7%) were diagnosed in FIGO III/IV. Pain was independent from age, FIGO stage, grading, amount of recurrences, and chemotherapy-free interval. ECOG was significantly worse in patients with pain (p < 0.001). Fatigue, nausea/vomiting, sleeping disorders, and abdominal symptoms such as loss of appetite, diarrhea, and constipation were more frequently found in patients with pain (all p < 0.001). Quality of life was significantly diminished (p < 0.001). Pain was also an independent marker for overall survival (OS). Median OS was 18.2 months in patients with pain compared with 22.0 months in patients without pain (p = 0.013, HR 1.25, 95% confidence interval 1.05-1.48). OS was shorter in patients with pain and without pain medication compared with those on sufficient pain medication, whereas OS was mostly decreased in patients having pain despite pain medication (18.5, 19.6, and 15.0 months respectively; p = 0.026). Progression-free survival and prior treatment discontinuation were not associated with pain.Conclusion: Best supportive care including sufficient pain medication should be delivered as early as possible because effective pain management is crucial for both quality of life and overall survival in patients with recurrent ovarian cancer.

Background: The aim of this study was to analyze the potential impact of chemotherapy-induced nausea and vomiting (CINV) on dose reductions, discontinuation of chemotherapy, and survival.Patients and Methods: This study was designed as individual participant data meta-analysis with the original study data of three phase II/III trials that were conducted by the North-Eastern German Society of Gynecological Oncology (NOGGO) including 1213 patients with recurrent ovarian cancer. Logistic and Cox regression analyses were used to estimate odds and hazard ratios after adjusting for age, ECOG, amount of delivered cycles, amount of recurrences, and amount of comedications and study.Results: The majority of patients developed nausea (58.1%) and almost one third experienced vomiting (31.0%). CINV was not associated with FIGO stage, grading, histology, and number of recurrences. The necessity of dose reduction and discontinuation of chemotherapy did not correlate to nausea and vomiting (p = 0.88, p = 0.39 and p = 0.25, p = 0.54 respectively). Progression-free survival was shorter in patients with grade III/IV nausea and vomiting (p = 0.02; hazard ratio (HR) for grade III/IV nausea 1.58, 95% CI 1.14-2.20, and p = 0.02; HR for grade III/IV vomiting 1.67, 95% CI 1.15-2.42 respectively). CINV grade III/IV was also associated with poorer overall survival (p < 0.001; HR for grade III/IV nausea 2.35, 95% CI 1.64-3.37, and p < 0.001; HR for grade III/IV vomiting 1.67, 95% CI 1.15-2.42 respectively).Conclusion: CINV is significantly associated with poorer prognosis in recurrent ovarian cancer patients while there was no correlation found with the necessity of dose reduction and prior discontinuation of treatment. This study underlines the importance of prevention and treatment of CINV as part of early best supportive care. [ABSTRACT FROM AUTHOR]- Published

Purpose: Palmoplantar erythrodysesthesia (PPE) is one of the most frequent side effects during systemic treatment with pegylated liposomal doxorubicin (PLD, Caelyx®). PPE lesions show a range of symptoms, from numbness to painful erosions, and can have a major impact on the quality of life in affected patients. Previously, a possible pathomechanism of PPE was found in doxorubicin-treated patients based on radical formation in the skin. Here, a preventive strategy using a topically applied ointment with a high radical protection factor was investigated.Methods: In this randomized placebo-controlled double-blind study the antioxidant-containing ointment was compared with a placebo ointment regarding PPE grade III occurrence, overall PPE grade I-III occurrence and PPE severity in PLD patients. The verum or placebo cream was topically applied for a period of 16 weeks, starting 3 days prior to the first cycle of chemotherapy. Clinical evaluations were carried out by a dermatologist prior to the first cycle of chemotherapy and every 4 weeks for the duration of 16 weeks.Results: Thirty-two patients were enrolled in total, of which 17 (66%) completed the study. No PPE grade III was found in the verum group, while five out of seven patients (71%) had to be unblinded in the placebo arm due to PPE grade III (p = 0.003). General PPE occurrence of all grades was 60% under verum and 86% under placebo treatment.Conclusions: The preventive application of an antioxidant-containing ointment was shown to be significantly more effective in the prevention of PPE grade III compared to placebo treatment.

Background:This is the first study investigating the safety and efficacy of the trifunctional antibody catumaxomab administered i.p. at the end of cytoreductive surgery and postoperatively prior to standard chemotherapy in patients with primary epithelial ovarian cancer (EOC).Methods:Patients received i.p. catumaxomab 10 μg intraoperatively and 10, 20, 50 and 150 μg on days 7, 10, 13 and 16, respectively, postoperatively. After the study, patients received standard chemotherapy and were followed for 23 months. The primary endpoint was the rate of postoperative complications.Results:Forty-one patients entered the study and were evaluable for safety and 34 were alive at 24 months. Complete tumour resection rate was 68%. Postoperative complications were observed in 51%, the most common anastomotic leakage (7%) and wound infections (5%). The most common catumaxomab-related adverse events were abdominal pain, nausea, vomiting and pyrexia. Thirty-nine percent discontinued catumaxomab therapy, and 98% received chemotherapy post study. Kaplan-Meier estimates of disease-free and overall survival after 24 months were 56% and 85%, respectively.Conclusions:Intra- and close postoperative catumaxomab seems feasible, but efficacy and safety were limited by postsurgical complications. In the future prospective trials are needed to investigate the best schedule of integration of catumaxomab into current treatment strategies for EOC. [ABSTRACT FROM AUTHOR]

The aim of this survey was to analyse the standard of care in diagnostic, surgery, chemotherapy and aftercare management for patients with borderline tumours of the ovary (BOTs) in Germany. A structured questionnaire comprising different dimensions was sent to all 1114 gynaecological departments. The questionnaire could be returned anonymously. The overall response rate was 29.0% (323 departments). Most departments were on secondary care (71.8%), tertiary care (23.2%) or university hospital (5.0%) level. Most clinicians performed not more than five BOT operations (89.2%) per year. Most departments (93.2%) used in addition to classical bimanual examination and vaginal ultrasound, tumour marker CA-125 detection, CT scan, MRI or PET-CT techniques. Departments in university and tertiary care hospitals performed more often a fresh frozen section (87 vs 64%). In young women, clinicians performed much seldom unilateral salpingo-oophorectomy (92%) and only in 53% biopsies of the contralateral ovary. Generally, biopsies of the contralateral ovary were performed in 4-53% of the patients. Chemotherapy was mostly favoured in 'high-risk' patients with tumour residual, microinvasion or invasive implants. Thus, a high grade of insecurity in diagnostic and therapy of BOT exists in some gynaecological departments and underlines the need for more educational and study activities. [ABSTRACT FROM AUTHOR]
