Background: Extensive surgery on advanced-stage epithelial ovarian cancer is associated with increased postoperative morbidity, which may cause a delay in or omission of chemotherapy. We examined postoperative complications and their effects on adjuvant treatment in patients undergoing primary debulking surgery (PDS). Methods: Stage IIIC-IV epithelial ovarian cancer patients who underwent PDS between January 2013 and December 2020 were included. Patients were divided into two groups according to the radicality of the operation, i.e., extensive or standard surgery, and their outcomes were compared. Results: In total, 172 patients were included; 119 underwent extensive surgery, and 53 had standard surgery. Clavien–Dindo grade 3–5 (CDC 3+) complications were detected in 41.2% of patients after extensive operations and in 17% after standard surgery (p = 0.002). The most common CDC 3+ complication was pleural effusion. Despite the difference in the complication rates, the delay in chemotherapy did not differ between the extensive and standard groups (p = 0.98). Conclusions: Complications are common after PDS. Extensive surgery increases the complication rate, but most complications can be treated effectively; therefore, a delay in adjuvant treatment is rare.

Background: Gynecological surgery has many impacts on women’s physical and mental health, and efforts to improve recovery from surgery are constantly under evaluation. Resilience is an ability to overcome stressors and adversities, such as traumas and surgeries. This study aimed to explore patients’ resilience and psychological symptoms in relation to recovery, health-related quality of life (HRQoL), and pain one year after gynecological surgery. Methods: In a prospective cohort study, we enrolled consecutive elective gynecologic surgery patients who completed questionnaires before and at one year after surgery: the Resilience Scale-25, the 15D instrument of HRQoL (15D), the Life Satisfaction Scale-4, and the Hospital Anxiety and Depression Scale. Their mean 15D scores were compared to those of an age-matched sample of women from the general Finnish population (n = 2743). Results: We enrolled 271 women who underwent gynecological surgery due to benign (n = 190) and malignant (n = 81) diagnoses. Resilience was equally high in women with benign and malignant diagnoses at both time points. Higher resilience associated with less pain, analgesic use, and better pain relief from the use of pain medication at 12 months after surgery. Pain intensity was similar in the two groups, but patients with benign diseases had less pain at 12 months than before surgery. Before surgery, patients’ HRQoL was worse than that of the general population, but at 12 months the mean HRQoL of patients with benign diseases had improved to the same level as that in the general population but had decreased further in patients with malignant diseases. Anxiety was higher and life satisfaction was lower in patients with malignant diseases before surgery. At 12 months, anxiety had decreased in both groups, and life satisfaction had increased in patients with malignant diseases. Depression was similarly low in both groups and time points. Conclusions: Resilience correlated with less pain one year after surgery. After surgery, HRQoL improved in patients with benign diseases but deteriorated in patients with malignant diseases. Patients with low resilience should be identified during preoperative evaluation, and health care professionals should give these patients psychological support to enhance their resilience.

The management of advanced epithelial ovarian cancer (AOC) has undergone significant advancements with the emergence of molecular diagnostics, particularly in predicting responses to PARP inhibitors (PARPi) based on homologous recombination deficiency (HRD) status. However, understanding sensitivity and resistance beyond HRD status remains elusive. This study aims to explore molecular factors that may elucidate why HRD status does not consistently predict PARPi sensitivity. Therefore, we conducted a post hoc translational analysis of formalin-fixed paraffin-embedded tumor samples from the ENGOT-ov24/NSGO-AVANOVA part 1 and 2 trial (NCT02354131), focusing on alterations pertaining radiologic response and progression-free survival (PFS). DNA sequencing was performed using the TruSight Oncology 500 HT gene panel, with variants classified according to recent guidelines. HRD status had been assessed by Myriad MyChoice CDx. We identified, among 92 patients in the ENGOT-ov24/NSGO-AVANOVA part 1 and 2 trial, 151 pathogenic or likely pathogenic variants across 81 samples. PARPi-sensitizing variants were found in two out of 10 HRD-negative samples from patients with clinical benefit (PFS ≥12 months), whereas three out of 10 HRD-positive samples from patients having no benefit (PFS ≤6 months) harbored variants associated with PARPi resistance. Additionally, analysis of BRCA1 variants revealed that truncating variants in exon 11 correlated with clinical benefit when niraparib was combined with bevacizumab. Conclusively, our findings highlight the complexity of PARPi response in AOC and underscore the importance of exploring somatic variants beyond HRD status. Further investigation into exon 11 variants of BRCA1 and the potential of combination treatment is warranted. Significance: The irregular response to PARPi in HRD-positive and -negative tumors highlights the need for identifying additional biomarkers. This study explores the mutational landscape beyond HRD status in AOC, ultimately advancing precision oncology in future clinical practice.

Purpose: We evaluated patients’ functional outcomes 2 weeks after a 23-h surgery model in a tertiary care hospital. Methods: This prospective study comprised data on 993 consecutive adult patients who underwent a 23-h surgery. Patients were interviewed before surgery and at 14 days after surgery by telephone with a multidimensional structural survey including closed- and open-ended questions. Regarding functional outcomes, the patients were asked to assess their general wellbeing, energy levels and activities of daily living on a 5-point numeric rating scale (1 = poor to 5 = excellent). Data on patient characteristics, medical history, alcohol use, smoking status and pre-, peri- and postoperative pain and satisfaction with the care received were collected and analysed to determine whether these factors contributed to their recovery. The primary outcome measure was patient functional recovery at 14 days after surgery. Results: Most patients reported moderate to excellent functional outcomes: 93.6% (95% CI, 92.1–-95.1) of the patients showed a score ≥ 3 on the 5-point numeric scale. One out of four patients (23%) scored all three domains as excellent. A weak inverse correlation was noted between functional recovery and most pain in the 23-h postanaesthesia care unit as well as pain at 2 weeks after surgery. A weak positive correlation was noted between functional recovery and patient satisfaction with the instructions at discharge. Conclusions: Most patients showed ample functional recovery at 14 days after the 23-h surgery. Higher pain scores in the postanaesthesia care unit and 2 weeks after surgery predicted poor functional outcomes, and satisfaction with postoperative counselling predicted better outcomes.
