Expanding the Use of HIPEC in Ovarian Cancer at Time of Interval Debulking Surgery to FIGO Stage IV and After 6 Cycles of Neoadjuvant Chemotherapy: A Prospective Analysis on Perioperative and Oncologic Outcomes.

BACKGROUND: Randomized data on patients with FIGO stage III ovarian cancer receiving ≤ 3 cycles of neoadjuvant chemotherapy (NACT) showed that hyperthermic intraperitoneal chemotherapy (HIPEC) after interval debulking surgery (IDS) improved patient's survival. We assessed the perioperative outcomes and PFS of FIGO stage IV and/or patients receiving up to 6 cycles of NACT undergoing IDS+HIPEC. METHODS: Prospectively collected cases from January 1, 2019 to July 31, 2022 were included. Patients underwent HIPEC if: age ≥ 18 years but < 75 years, body mass index ≤ 35 kg/m2, ASA score ≤ 2, FIGO stage III/IV epithelial disease treated with up to 6 cycles of NACT, and residual disease < 2.5 mm. RESULTS: A total of 205 patients were included. No difference was found in baseline characteristics between FIGO Stage III and IV patients, whereas rate of stable disease after NACT (p = 0.004), mean surgical complexity score at IDS (p = 0.001), and bowel resection rate (p = 0.046) were higher in patients undergoing delayed IDS. A lower rate of patients with at least one G3-G5 postoperative complications was observed in FIGO stage IV versus FIGO stage III disease (5.3% vs. 14.0%; p = 0.052). This difference was confirmed at multivariable analysis (odds ratio [OR] 0.24; 95% confidence interval [CI] 0.07-0.80; p = 0.02), whereas age, SCS, bowel resection, and number of cycles did not affect postoperative complications. No difference in PFS was identified neither between FIGO stage III and IV patients (p = 0.44), nor between 3 and 4 versus > 4 cycles of NACT (p = 0.85). CONCLUSIONS: Because of the absence of additional complications and positive survival outcomes, HIPEC administration can be considered in selected FIGO stage IV and patients receiving > 4 cycles of NACT.

Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) Applied to Platinum-Resistant Recurrence of Ovarian Tumor: A Single-Institution Experience (ID: PARROT Trial).

BACKGROUND: We aimed to investigate the therapeutic efficacy and safety of Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) in platinum-resistant recurrence of ovarian cancer and peritoneal carcinomatosis, while our secondary endpoint was to establish any changes in quality of life estimated via the EORTC QLQ-30 and QLQ-OV28 questionnaires. METHODS: In this monocentric, single-arm, phase II trial, women were prospectively recruited and every 28-42 days underwent courses of PIPAC with doxorubicin 2.1 mg/m2 followed by cisplatin 10.5 mg/m2 via sequential laparoscopy. RESULTS: Overall, 98 PIPAC procedures were performed on 43 women from January 2016 to January 2020; three procedures were aborted due to extensive intra-abdominal adhesions. The clinical benefit rate (CBR) was reached in 82% of women. Three cycles of PIPAC were completed in 18 women (45%), and 13 (32.5%) and 9 (22.5%) patients were subjected to one and two cycles, respectively. During two PIPAC procedures, patients experienced an intraoperative intestinal perforation. There were no treatment-related deaths. Nineteen patients showed no response according to the Peritoneal Regression Grading Score (PRGS) and 8 patients showed minor response according to the PRGS. Median time from ovarian cancer relapse to disease progression was 12 months (95% confidence interval [CI] 6.483-17.517), while the median overall survival was 27 months (95% CI 20.337-33.663). The EORTC QLQ-28 and EORTC QLQ-30 scores did not worsen during therapy. CONCLUSIONS: PIPAC seems a feasible approach for the treatment of this subset of patients, without any impact on their quality of life. Since this study had a small sample size and a single-center design, future research is mandatory, such as its application in addition to systemic chemotherapy.

Distribution and prognostic role of BRCA status in elderly ovarian cancer patients.

OBJECTIVE: In the era of target therapy and personalized medicine, BRCA mutational status has a major influence on survival in ovarian cancer patients. Our aim is to verify if the poorer prognosis of elderly ovarian cancer patients can be related to the biology of the tumor beyond their own morbidities and/or suboptimal treatments. METHODS: This is a retrospective single-institution study evaluating prognosis of patients with a diagnosis of ovarian cancer and known BRCA status. We collected clinical and surgical characteristics and the distribution of BRCA mutational status according to age groups. RESULTS: 1840 patients were included in the analysis. The rate of BRCA mutated decreased over age-range from 49.7% in patients aged <50 years to 18.8% in ≥80 years old women. The prognostic role of BRCA status on survival is maintained when focusing on the elderly population, with improved Disease Free Survival (27.2 months vs 16.5 months for BRCA mutated and wild type respectively, p = 0.001) and Cancer Specific Survival (117.6 months vs 43.1 months for BRCA mutated and wild type respectively, p = 0.001) for BRCAmut compared to BRCAwt patients. In the multivariable analysis, among elderly women, upfront surgery and BRCA mutation are independent factors affecting survival. CONCLUSIONS: Elderly patients experiment a poorer prognosis due to multiple factors that include both their medical condition and comorbidities, under-treatment and most importantly disease characteristics. We found that beyond disparities, BRCA mutation is still the strongest independent prognostic factor affecting both the risk of recurrence and death due to disease.

Low-grade versus high-grade serous ovarian cancer: comparison of surgical outcomes after secondary cytoreductive surgery.

OBJECTIVE: Retrospective series have shown secondary cytoreductive surgery improves oncological outcomes in recurrent low-grade serous ovarian cancer. We aim to compare surgical procedures and complications between patients with low-grade and high-grade recurrent serous ovarian cancer. METHODS: This retrospective single-institution study includes patients with recurrent low-grade and high-grade serous ovarian cancer undergoing surgery between January 2012 to December 2021. Patients were propensity matched 1:3 for residual tumor at first surgery, presence of ascites and performance status. Complexity of surgery and postoperative complications were analyzed. RESULTS: A total of 116 patients undergoing secondary cytoreductive surgery were included with 29 patients (25%) having low-grade ovarian cancer. The median age of the patients was 54 years (range: 19-85) and 57 years (range: 29-78) in low-grade and high-grade ovarian cancer, respectively (p=0.13). Stages III/IV at diagnosis were more frequent in patients with high-grade ovarian cancers (p<0.001). Peritoneal involvement was higher in low-grade compared with high-grade ovarian cancer as shown by the higher rate of diaphragmatic (41.4% vs 21.8%, p=0.05), abdominal wall (41.4% vs 18.4%, p=0.02) and pelvic (51.7% vs 21.8%, p=0.01) peritonectomy. Multiple bowel resections were higher in low-grade ovarian cancer (24.1% vs 8.0%, p=0.04), while high-grade ovarian cancer had a higher rate of nodal recurrences (73.2%% vs 37.9%, p=0.03). Overall, surgical complexity was higher in low-grade ovarian cancer (58.6% vs 36.8%; p=0.05), with higher median estimated blood loss (400 vs 200 mL; p=0.01) compared with high-grade. Complete cytoreduction was achieved in 26 patients (89.7%) with low-grade and 84 (96.6%) with high-grade (p=0.16) ovarian cancer, with no significant differences in postoperative complications. CONCLUSIONS: Secondary cytoreductive surgery in low-grade serous ovarian cancer patients was associated with higher complexity, multiple bowel resections, and higher median estimated blood loss than in high-grade serous ovarian cancer. The comparable rate of postoperative complications suggests that secondary cytoreductive surgery in this group of patients is feasible in expert centers.

Visual Peritoneal Evaluation of Residual Disease After Neoadjuvant Chemotherapy in Advanced Ovarian Cancer Patients: The VIPER Study.

BACKGROUND: Chemotherapy induces histopathological tumor necrosis and fibrosis which results in macroscopic tissue changes, making surgeons' intraoperative visual evaluation of the disease distribution more difficult to interpret. The aim of the study was to assess the sensitivity, specificity, and accuracy of intraoperative laparoscopic visual evaluation of the diaphragmatic peritoneum and compare it with histopathological examination. METHODS: Patients receiving diaphragmatic peritonectomy at time of IDS were retrospectively included. The population was grouped based on the surgeon's assessment of the diaphragmatic peritoneum during diagnostic laparoscopy. Group 1 included patients with a "visually pathologic" diaphragmatic peritoneum, and group 2 included patients with a "visually dubious" diaphragmatic peritoneum. Sensitivity, specificity, predictive values, and accuracy were calculated considering the final formalin-fixed pathology as the reference standard. RESULTS: 155 patients were included (92 in group 1 and 63 in group 2). The accuracy rate of visual examination was 67.1%, the negative predictive value was 19%, specificity was 100%, and sensitivity was 64.3%. CONCLUSION: NACT strongly affects the ability of the surgeon to discern between peritoneal scars and truly pathologic peritoneum. The diaphragmatic laparoscopic visual examination showed a low overall accuracy. We propose an algorithm that can guide the surgeon towards a more tailored approach to diaphragmatic peritonectomy during IDS.

Quality of life in patients with advanced ovarian cancer after primary debulking surgery versus neoadjuvant chemotherapy: Results from the randomised SCORPION trial (NCT01461850).

OBJECTIVE: To investigate the effect of treatment with neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS), versus primary debulking surgery (PDS), on quality of life (QoL) in patients with advanced epithelial ovarian cancer (EOC). DESIGN: Randomised trial conducted in a single institution. SETTING: Division of Gynaecologic Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. SAMPLE: Patients with stage-IIIC/IV EOC and high tumour load. METHODS: Patients were randomised (1:1) to undergo either PDS (PDS group) or NACT followed by IDS (NACT/IDS group). MAIN OUTCOME MEASURES: Quality-of-life (QoL) data, assessed using the European Organization for Research and Treatment of Cancer core QoL questionnaire (QLQ-C30) and ovarian cancer module (OV28); co-primary outcomes were the QLQ-C30 global health score at 12 months (cross-sectional analysis) and the difference in mean QLQ-C30 global health score over time between treatment groups (longitudinal analysis). RESULTS: From October 2011 to May 2016, 171 patients were enrolled (PDS = 84; NACT/IDS = 87). We observed no clinical or statistically significant difference between treatment groups in any of the QoL functioning scales at 12 months, including QLQ-C30 global health score (NACT/IDS group vs PDS group, mean difference 4.7, 95% CI -4.99 to 14.4, p = 0.340). Over time, we found lower global health scores for those undergoing PDS than for those receiving NACT (difference in mean score 6.27, 95% CI 0.440-12.11, p = 0.035), albeit this was not clinically relevant. CONCLUSIONS: We found no difference in global QoL related to treatment approach at 12 months, even though patients in the NACT/IDS group reported better global health scores across the 12-month period compared with the PDS group; these findings further confirm that NACT/IDS might be a feasible option for patients unsuitable for PDS.

Minimally invasive versus open pelvic exenteration in gynecological malignancies: a propensity-matched survival analysis.

OBJECTIVE: The primary endpoint of this study was to compare the disease-free survival of patients undergoing open versus minimally invasive pelvic exenteration. The secondary endpoints were cancer-specific survival and peri-operative morbidity. METHODS: A multi-center, retrospective, observational cohort study was undertaken. Patients undergoing curative and palliative anterior or total pelvic exenteration for gynecological cancer by a minimally invasive approach and an open approach between June 2010 and May 2021 were included. Patients with distant metastases were excluded. A 1:2 propensity match analysis between patients undergoing minimally invasive and open pelvic exenteration was performed to equalized baseline characteristics. RESULTS: After propensity match analysis a total of 117 patients were included, 78 (66.7%) and 39 (33.3%) in the open and minimally invasive group, respectively. No significant difference in intra-operative (23.4% vs 10.3%, p=0.13) and major post-operative complications (24.4% vs 17.9%, p=0.49) was evident between the open and minimally invasive approach. Patients undergoing open pelvic exenteration received higher rates of intra-operative transfusions (41.0% vs 17.9%, p=0.013). Median disease-free survival was 17.0 months for both the open and minimally invasive groups (p=0.63). Median cancer-specific survival was 30.0 months and 26.0 months in the open and minimally invasive groups, respectively (p=0.80). Positivity of surgical margins at final histology was the only significant factor influencing the risk of recurrence (hazard ratio (HR) 2.38, 95% CI 1.31 to 4.31) (p=0.004), while tumor diameter ≥50 mm at the time of pelvic exenteration was the only significant factor influencing the risk of death (HR 1.83, 95% CI 1.08 to 3.11) (p=0.025). CONCLUSION: In this retrospective study no survival difference was evident when minimally invasive pelvic exenteration was compared with open pelvic exenteration in patients with gynecological cancer. There was no difference in peri-operative complications, but a higher intra-operative transfusion rate was seen in the open group.

Risk Factors for Anastomotic Leakage in Advanced Ovarian Cancer Surgery: A Large Single-Center Experience.

BACKGROUND: Cytoreductive surgery is currently the main treatment for advanced epithelial ovarian cancer (OC), and several surgical maneuvers, including colorectal resection, are often needed to achieve no residual disease. High surgical complexity carries an inherent risk of postoperative complications, including anastomosis leakage (AL). Albeit rare, AL is a life-threatening condition. The aim of this single-center retrospective study is to assess the AL rate in patients undergoing colorectal resection and anastomosis during primary surgery for advanced epithelial OC through a standardized surgical technique and to evaluate possible pre/intra- and postoperative risk factors to identify the population at greatest risk. METHODS: A retrospective analysis of clinical and surgical characteristics of 515 patients undergoing colorectal resection and anastomosis during primary or interval debulking surgery between December 2011 and October 2019 was performed. Several pre/intra- and postoperative variables were evaluated by multivariate analysis as potential risk factors for AL. RESULTS: The overall anastomotic leakage rate was 2.9% (15/515) with a significant negative impact on postoperative course. Body mass index < 18 kg/m2, preoperative albumin value lower than 30 mg/dL, section of the inferior mesenteric artery at its origin, and medium-low colorectal anastomosis (< 10 cm from the anal verge) were identified as independent risk factors for AL on multivariate analysis. CONCLUSIONS: AL is confirmed to be an extremely rare but severe postoperative complication of OC surgery, being responsible for increased early postoperative mortality. Preoperative nutritional status and surgical characteristics, such as blood supply and anastomosis level, appear to be the most significant risk factors.

Peritoneal HPV-DNA test in cervical cancer (PIONEER study): A proof of concept.

The aim of this study was to investigate the prevalence of peritoneal human papillomavirus (HPV) infection in different clinical cervical cancer (CC) settings, and its association with potential clinical and/or histological factors. This is a single-center, prospective, observational study. Consecutive patients with newly diagnosed or recurrent/persistent CC, between March 2019 and April 2020, were included. A group of patients undergoing surgery for benign gynecological conditions was included as control group. All patients underwent HPV-DNA test in the cervix and in the peritoneal cavity simultaneously at time of surgery. Two-hundred seventy-two patients had cervical and peritoneal HPV test analyzed. Cervical and peritoneal HPV positivity (PHP) was found in 235 (88.0%) and 78 (28.7%) patients, respectively; the prevalence of PHP was 17.7% in early stage, 28.8% in locally advanced cervical cancer (LACC) and 46.6% in the metastatic/persistent/recurrent setting (P = .001). No control patient was found to have peritoneal HPV infection. Higher frequency of PHP was documented in patients with larger tumor size (P = .003), presence of cervical HPV 16/18 genotypes (P < .001), higher number of cervical high-risk (HR)-HPV per patient (P = .018) and peritoneal carcinomatosis (P < .001). Multivariate analysis demonstrated that lack of preoperative cervical conization in early stages (P = .030), while higher International Federation of Gynecology and Obstetrics (FIGO) stage (P = .021) and presence of cervical HPV 16/18 (P = .001) in LACC, was associated with PHP. This is a proof-of-concept study. A number of potential clinical implications, including prognosis, could be obtained by further studies.

Randomized trial of primary debulking surgery versus neoadjuvant chemotherapy for advanced epithelial ovarian cancer (SCORPION-NCT01461850).

OBJECTIVE: To investigate whether neoadjuvant chemotherapy followed by interval debulking surgery is superior to primary debulking surgery in terms of perioperative complications and progression-free survival, in advanced epithelial ovarian, fallopian tube or primary peritoneal cancer patients with high tumor load. METHODS: Patients with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer (stage IIIC-IV) underwent laparoscopy. Patients with high tumor load assessed by a standardized laparoscopic predictive index were randomly assigned (1:1 ratio) to undergo either primary debulking surgery followed by adjuvant chemotherapy (arm A), or neoadjuvant chemotherapy followed by interval debulking surgery and adjuvant chemotherapy (arm B). Co-primary outcome measures were progression-free survival and post-operative complications; secondary outcomes were overall survival, and quality of life. Survival analyses were performed on an intention-to-treat population. RESULTS: 171 patients were randomly assigned to primary debulking surgery (n=84) versus neoadjuvant chemotherapy (n=87). Rates of complete resection (R0) were different between the arms (47.6% in arm A vs 77.0% in arm B; p=0.001). 53 major postoperative complications were registered, mainly distributed in arm A compared with arm B (25.9% vs 7.6%; p=0.0001). All patients were included in the intent-to-treat analysis. With an overall median follow-up of 59 months (95% CI 53 to 64), 142 (83.0%) disease progressions/recurrences and 103 deaths (60.2%) occurred. Median progression-free and overall survival were 15 and 41 months for patients assigned to primary debulking surgery, compared with 14 and 43 months for patients assigned to neoadjuvant chemotherapy, respectively (HR 1.05, 95% CI 0.77 to 1.44, p=0.73; HR 1.12, 95% CI 0.76 to 1.65, p=0.56). CONCLUSIONS: Neoadjuvant chemotherapy and primary debulking surgery have the same efficacy when used at their maximal possibilities, but the toxicity profile is different.

Risk factors for bloodstream infections in gynecological cancer.

OBJECTIVE: Infections are a threat to frail patients as they have a higher risk of developing serious complications from bloodstream pathogens. The aim of this study was to determine which factors can predict or diagnose bloodstream infections in patients with an underlying gynecologic malignancy. MATERIALS AND METHODS: Between July 2016 and December 2017, 68 patients visiting the emergency room with an underlying gynecologic malignancy were evaluated. Variables concerning underlying disease, invasive procedures, and laboratory and clinical parameters were analyzed. Patients were divided into three groups based on their blood and urine specimens (positive blood specimens, positive urine specimens, and no positive specimens; patients who had both positive blood and urine specimens were included in the group of positive blood specimens). Risk factors for surgical site infections, recent (<30 days) surgery, and chemotherapy were studied separately. RESULTS: 68 patients were included in the analysis. Mean age was 55.6 years (standard deviation 14.1). 44% of patients had ovarian cancer, 35% cervical cancer, 12% endometrial cancer, and 9% had other cancer types. In total, 96% of all patients had undergone surgery. Patients who had been treated with chemotherapy were at a higher risk of developing bloodstream infection (P=0.04; odds ratio (OR)=7.9). C reactive protein, bilirubin, and oxygen saturation (SO2) were significantly different between patients with an underlying infection and those who had none. Only C reactive protein maintained its significance in a linear model, with a cut-off of 180 mg/L (linear regression, P=0.03; OR=4). CONCLUSIONS: Chemotherapy is a risk factor for the development of bloodstream infections in patients with an underlying gynecologic malignancy; C reactive protein could be a useful tool in making this diagnosis.

Airway Closure during Surgical Pneumoperitoneum in Obese Patients.

BACKGROUND: Airway closure causes lack of communication between proximal airways and alveoli, making tidal inflation start only after a critical airway opening pressure is overcome. The authors conducted a matched cohort study to report the existence of this phenomenon among obese patients undergoing general anesthesia. METHODS: Within the procedures of a clinical trial during gynecological surgery, obese patients underwent respiratory/lung mechanics and lung volume assessment both before and after pneumoperitoneum, in the supine and Trendelenburg positions, respectively. Among patients included in this study, those exhibiting airway closure were compared to a control group of subjects enrolled in the same trial and matched in 1:1 ratio according to body mass index. RESULTS: Eleven of 50 patients (22%) showed airway closure after intubation, with a median (interquartile range) airway opening pressure of 9 cm H2O (6 to 12). With pneumoperitoneum, airway opening pressure increased up to 21 cm H2O (19 to 28) and end-expiratory lung volume remained unchanged (1,294 ml [1,154 to 1,363] vs. 1,160 ml [1,118 to 1,256], P = 0.155), because end-expiratory alveolar pressure increased consistently with airway opening pressure and counterbalanced pneumoperitoneum-induced increases in end-expiratory esophageal pressure (16 cm H2O [15 to 19] vs. 27 cm H2O [23 to 30], P = 0.005). Conversely, matched control subjects experienced a statistically significant greater reduction in end-expiratory lung volume due to pneumoperitoneum (1,113 ml [1,040 to 1,577] vs. 1,000 ml [821 to 1,061], P = 0.006). With airway closure, static/dynamic mechanics failed to measure actual lung/respiratory mechanics. When patients with airway closure underwent pressure-controlled ventilation, no tidal volume was inflated until inspiratory pressure overcame airway opening pressure. CONCLUSIONS: In obese patients, complete airway closure is frequent during anesthesia and is worsened by Trendelenburg pneumoperitoneum, which increases airway opening pressure and alveolar pressure: besides preventing alveolar derecruitment, this yields misinterpretation of respiratory mechanics and generates a pressure threshold to inflate the lung that can reach high values, spreading concerns on the safety of pressure-controlled modes in this setting.

Goal-directed hemodynamic management in patients undergoing primary debulking gynaecological surgery: A matched-controlled precision medicine study.

BACKGROUND: Usefulness of intraoperative goal-directed hemodynamic management (GDHM) for patients without comorbidities is debated. After clinical implementation of a pulse contour analysis-guided GDHM protocol, which foresees early vasopressor use for recruiting unstressed volume, we conducted a matched-controlled analysis to explore its impact on the amount of fluids intraoperatively administered to patients without comorbidities who underwent extended abdominal surgery for ovarian cancer. METHODS: After 1:1 matching accounting for body mass index, oncologic disease severity and intraoperative blood losses, 22 patients treated according to this GDHM protocol were compared to a control group of 22 patients who had been managed according to the clinical decision of attending physicians, taken without advanced monitoring. Results are displayed as median[interquartile range]. RESULTS: All analyzed patients underwent radical hysterectomy, bilateral adnexectomy, bowel resection, peritonectomy and extended pelvic/periaortic lymphadenectomy; median length of surgery was 517[480-605] min in patients receiving GDHM and 507[480-600] min in control group. Intraoperatively, patients undergoing GDHM received less fluids (crystalloids 2950[2700-3300] vs. 5150[4700-6000] mL, p < 0.001; colloids 100[50-200] vs. 750[500-1000] mL, p < 0.001) and showed a trend to more frequent vasopressor administration (32 vs 9%, p = 0.13). Greater intraoperative diuresis (540[480-620] mL vs. 450[400-500] mL, p = 0.007), lower blood lactates at surgery end (1.5[1.1-2] vs. 4.1[3.3-5] mmol/L, p < 0.001), shorter time to bowel function recovery (1 [1, 2] vs. 4 [3-5] days, p < 0.001) and hospital discharge (7 [6-8] vs 12 [9-16] days, p < 0.0001) were detected in patients receiving GDHM. CONCLUSIONS: In high-tumor load gynaecological patients without comorbidities who receive radical and prolonged surgery, intraoperative use of this novel GDHM protocol helped limit fluids administration with safety.

Upfront HIPEC and bevacizumab-containing adjuvant chemotherapy in advanced epithelial ovarian cancer.

INTRODUCTION: In advanced epithelial ovarian cancer patients, the standard of care is primary debulking surgery, followed by first-line chemotherapy often with bevacizumab addiction. In this context, some experiences have shown that a comprehensive treatment approach to surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) could improve the prognosis. OBJECTIVE: This is a study aimed to explore the feasibility of primary debulking surgery and HIPEC upfront followed by first-line therapy with bevacizumab. STUDY DESIGN: Phase II monocentric, open label, non-randomised and single-arm study. Forty patients affected by advanced ovarian cancer submitted to primary debulking surgery with HIPEC were enrolled in the study. After surgery, all patients underwent systemic chemotherapy with bevacizumab addiction. RESULTS: Complete cytoreduction (RT = 0) was achieved in all cases. Treatment-related early complications were observed in 23 patients and in 15 cases were G1-G2. Major complications were reported in 8 patients. No postoperative death was recorded. Subsequent chemotherapy was administered in all cases. Median time between surgery and first cycle of chemotherapy was 42 days (range 30-76). Concomitant bevacizumab was administered in 34 patients (85%). Maintenance with bevacizumab was feasible in 33 patients (82.5%) and its withdrawal was necessary for 1 patient (2.5%) due to G3 hypertension. CONCLUSION: Our data suggest that HIPEC can be safely introduced in the upfront therapy of advanced ovarian cancer.

Bilateral Ureteral Stent Removal after 15 Years: A Case Report.

We present the first reported case of a patient with a forgotten ureteral stent. A 68-year-old woman had undergone radical hysterectomy for cervical cancer in 1997, at which time bilateral ureteral stents were placed. She was admitted to our hospital with stranguria, dysuria, and lower back pain of 10 days duration. Preoperative radiologic evaluation revealed the presence of ureteral stents, which had been in place since 1997. With the patient under general anesthesia, the bilateral stents were removed by urethral cystoscopy. No stone formation was noted. The procedure was easy and fast, and no intraoperative complications occurred.

Single-Institution Propensity-Matched Study to Evaluate the Psychological Effect of Minimally Invasive Interval Debulking Surgery Versus Standard Laparotomic Treatment: From Body to Mind and Back.

STUDY OBJECTIVE: To further investigate the psycho-oncologic effect of minimally invasive surgery comparing patients submitted to minimally invasive interval debulking surgery (MI-IDS) with a balanced population treated by standard laparotomy (L-IDS). DESIGN: Single-institution propensity-matched study (Canadian Task Force classification II-2). SETTING: Division of Gynecologic Oncology, "Policlinico A. Gemelli" Foundation, Rome, Italy. PATIENTS: The investigational arm included 30 patients with advanced ovarian cancer treated with MI-IDS, whereas the control arm included a consecutive series of 30 patients with advanced ovarian cancer submitted to L-IDS. For every patient preoperative data were collected to assess the response to neoadjuvant chemotherapy. Perioperative data were also recorded. INTERVENTIONS: A General Well-Being Schedule (GWBS) and a clinical assessment of body uneasiness, the Body Uneasiness Test, were administered by a psycho-oncologist immediately before IDS and within 30 days after surgery to evaluate the psychological burden in both groups. MEASUREMENT AND MAIN RESULTS: Both groups were matched as closely as possible. No statistical differences were registered in terms of surgical procedures and residual tumor. A significantly longer median operative time in patients was counterbalanced by more favorable estimated blood loss and median length of stay and time to chemotherapy. No statistically significant differences were registered in terms of postoperative complications. Starting from a substantially homogenous psychological condition, psychometric evaluation underlined statistically significant differences in favor of MI-IDS. The mean GWBS score was 64.17 ± 11.77 in patients and 54.15 ± 14.76 in control subjects, with a statistically significant difference between the 2 groups (p = .004). CONCLUSION: MI-IDS seems to play an important role in the quality of life and oncologic outcomes. Even if presented data testified a further evolutionary step in oncologic patient care, more experience with larger groups of patients is desirable to deeply investigate and assess our results.

Hepatoceliac Lymph Node Involvement in Advanced Ovarian Cancer Patients: Prognostic Role and Clinical Considerations.

BACKGROUND: The study aimed too investigate the rate of hepatoceliac lymph node (HCLN) involvement, as well as its association with clinicopathologic features, together with morbidity of HCLN resection and the prognostic impact of metastatic HCLN status on patients with advanced ovarian cancer (OC) undergoing cytoreductive surgery. METHODS: All consecutive patients with stages 3c to 4 epithelial OC who underwent HCLN surgery from January 2010 to September 2016 were analyzed for surgical procedures, pathology, and oncologic outcomes. RESULTS: During the study period, 85 patients underwent HCLN resection. Absence of visible tumor at the end of surgery was documented for 73 of the patients (85.9%). The median number of HCLNs removed was 6 (range 1-18). Histopathologic evaluation was able to identify HCLN metastasis in 45 (52.9%) of the 85 cases. No difference in the rate of surgical morbidity according to pathologic status of HCLN was observed. As of December 2016, the median follow-up period was 36 months (range 6-54 months). Recurrence of disease was observed in 35 (41.2%) of the 85 cases. Relapse of disease most frequently occurred for the patients with metastatic HCLN involvement (65.7%) compared with the patients who had no HCLN involvement (34.3%) (p = 0.048). The median progression-free survival values were 16 months (95% confidence interval [CI], 12-19 months) for the patients with metastatic HCLNs and 22 months (95% CI, 12-19 months) for the patients with no HCLN involvement (p = 0.035). CONCLUSIONS: The study confirmed that HCLN surgery is feasible with acceptable morbidities for patients with advanced OC. Metastatic HCLNs are a marker of disease severity associated with worst oncologic outcome.
