- The standard chemotherapy for ovarian cancer is paclitaxel/carboplatin. Patients often exhibit myelosuppressive toxicity, and the treatment response varies considerably. In this study, we investigated the previously reported SNPs 1199Gamp;gt;A (rs2229109), 1236Camp;gt;T (rs1128503), 2677Gamp;gt;T/A (rs2032582), 3435Camp;gt;T (rs1045642) in ABCB1, and 1196Aamp;gt;G (rs10509681) in CYP2C8 and their association with treatment-induced myelosuppression, progression-free survival (PFS) and overall survival (OS). From the phase III study, OAS-07OVA, 525 patients (All) treated with carboplatin and paclitaxel administered as Paclical (Arm A, n=260) or Taxol((R)) (Arm B, n=265) were included and genotyped using pyrosequencing. Genotype associations with myelosuppression, PFS and OS were investigated using anova, Kaplan-Meier analysis and Cox proportional hazard models. The most prominent finding was for the ABCB1 variant 3435TT, which was significantly associated with increased PFS in All (hazard ratio (HR) = 0.623), in Arm A (HR=0.590) and in Arm B (HR=0.627), as well as increased OS in All (HR=0.443) and in Arm A (HR=0.372) compared to the wild-type, 3435CC. For toxicity, the most interesting finding concerned the haplotype, including 1236TT, 2677TT and 3435TT, which was associated with higher neutrophil values in Arm B (p=0.039) and less neutrophil decrease in All (p=0.048) and in Arm B (p=0.021). It is noteworthy that the results varied depending on the treatment arm which indicates that the effects of ABCB1 variants vary with the treatment regimen. Our results reflect the contradictory results of previous studies, confirming that small variations in the composition of treatment regimens and patient populations may influence the interpretation of SNPs effects on treatment outcome.

Forskningsöversikt (refereegranskat)abstract
- The 4th Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup was held in Vancouver, Canada, in June 2010. Representatives of 23 cooperative research groups studying gynecologic cancers gathered to establish international consensus on issues critical to the conduct of large randomized trials. Group C, 1 of the 3 discussion groups, examined recurrent ovarian cancer, and we report the consensus reached regarding 4 questions. These included the following: (1) What is the role of cytoreductive surgery for recurrent ovarian cancer? (2) How do we define distinct patient populations in need of specific therapeutic approaches? (3) Should end points for trials with recurrent disease vary from those of first-line trials? (4) Is CA-125 progression alone sufficient for entry/eligibility into clinical trials?

Tidskriftsartikel (refereegranskat)abstract
- A locus at 19p13 is associated with breast cancer (BC) and ovarian cancer (OC) risk. Here we analyse 438 SNPs in this region in 46,451 BC and 15,438 OC cases, 15,252 BRCA1 mutation carriers and 73,444 controls and identify 13 candidate causal SNPs associated with serous OC (P=9.2 × 10-20), ER-negative BC (P=1.1 × 10-13), BRCA1-associated BC (P=7.7 × 10-16) and triple negative BC (P-diff=2 × 10-5). Genotype-gene expression associations are identified for candidate target genes ANKLE1 (P=2 × 10-3) and ABHD8 (P<2 × 10-3). Chromosome conformation capture identifies interactions between four candidate SNPs and ABHD8, and luciferase assays indicate six risk alleles increased transactivation of the ADHD8 promoter. Targeted deletion of a region containing risk SNP rs56069439 in a putative enhancer induces ANKLE1 downregulation; and mRNA stability assays indicate functional effects for an ANKLE1 3′-UTR SNP. Altogether, these data suggest that multiple SNPs at 19p13 regulate ABHD8 and perhaps ANKLE1 expression, and indicate common mechanisms underlying breast and ovarian cancer risk.

Tidskriftsartikel (refereegranskat)abstract
- Background: We evaluated the efficacy and safety of the aromatase inhibitor exemestane in patients with advanced, persistent or recurrent endometrial carcinoma. Methods: We performed an open-label one-arm, two-stage, phase II study of 25 mg of oral exemestane in 51 patients with advanced (FIGO stage III-IV) or relapsed endometrioid endometrial cancer. Patients were stratified into subsets of estrogen receptor (ER) positive and ER negative patients. Results: Recruitment to the ER negative group was stopped prematurely after 12 patients due to slow accrual. In the ER positive patients, we observed an overall response rate of 10%, and a lack of progression after 6 months in 35% of the patients. No responses were registered in the ER negative patients, and all had progressive disease within 6 months. For the total group of patients, the median progression free survival (PFS) was 3.1 months (95% CI: 2.0-4.1). In the ER positive patients the median PFS was 3.8 months (95% CI: 0.7-6.9) and in the ER negative patients it was 2.6 months (95% CI: 2.1-3-1). In the ER positive patients the median overall survival (OS) time was 13.3 months (95% CI: 7.7-18.9), in the ER negative patients the corresponding numbers were 6.1 months (95% CI: 4.1-8.2). Treatment with exemestane was well tolerated. Conclusion: Treatment of estrogen positive advanced or recurrent endometrial cancer with exemestane, an aromatase inhibitor, resulted in a response rate of 10% and lack of progression after 6 months in 35% of the patients.

- PURPOSE The Groningen International Study on Sentinel nodes in Vulvar cancer (GROINSS-V)-II investigated whether inguinofemoral radiotherapy is a safe alternative to inguinofemoral lymphadenectomy (IFL) in vulvar cancer patients with a metastatic sentinel node (SN). METHODS GROINSS-V-II was a prospective multicenter phase-II single-arm treatment trial, including patients with early-stage vulvar cancer (diameter < 4 cm) without signs of lymph node involvement at imaging, who had primary surgical treatment (local excision with SN biopsy). Where the SN was involved (metastasis of any size), inguinofemoral radiotherapy was given (50 Gy). The primary end point was isolated groin recurrence rate at 24 months. Stopping rules were defined for the occurrence of groin recurrences. RESULTS From December 2005 until October 2016, 1,535 eligible patients were registered. The SN showed metastasis in 322 (21.0%) patients. In June 2010, with 91 SN-positive patients included, the stopping rule was activated because the isolated groin recurrence rate in this group went above our predefined threshold. Among 10 patients with an isolated groin recurrence, nine had SN metastases > 2 mm and/or extracapsular spread. The protocol was amended so that those with SN macrometastases (> 2 mm) underwent standard of care (IFL), whereas patients with SN micrometastases (<= 2 mm) continued to receive inguinofemoral radiotherapy. Among 160 patients with SN micrometastases, 126 received inguinofemoral radiotherapy, with an ipsilateral isolated groin recurrence rate at 2 years of 1.6%. Among 162 patients with SN macrometastases, the isolated groin recurrence rate at 2 years was 22% in those who underwent radiotherapy, and 6.9% in those who underwent IFL (P = .011). Treatment-related morbidity after radiotherapy was less frequent compared with IFL. CONCLUSION Inguinofemoral radiotherapy is a safe alternative for IFL in patients with SN micrometastases, with minimal morbidity. For patients with SN macrometastasis, radiotherapy with a total dose of 50 Gy resulted in more isolated groin recurrences compared with IFL.

Tidskriftsartikel (refereegranskat)abstract
- Malignant ascites is a common phenomenon in cancer patients. It poses a great challenge to the clinician, because of limited treatment options and strong impairment of the quality of life of the often palliative patients. The SECIMAS study investigated the feasibility of a re-challenge with four catumaxomab intraperitoneal infusions in patients who had already received a first cycle of four infusions in the phase III CASIMAS study, which compared catumaxomab with and without prednisolone premedication. The primary endpoint was the proportion of patients who received at least three catumaxomab infusions. Secondary endpoints included a composite safety score (CSS) summarising the worst grades for the main catumaxomab-related adverse events (pyrexia, nausea, vomiting and abdominal pain), safety, efficacy and the occurrence of anti-drug antibodies (ADAs). Eight of nine screened patients received a second catumaxomab cycle. Compliance with a catumaxomab re-challenge was high: all eight patients (100 %) received all four infusions. The median CSS was 3.0 versus 3.4 in CASIMAS. The tolerability profile of the second catumaxomab cycle was comparable to that of the first cycle. Median puncture-free survival (48 days) and overall survival (407 days) were longer than in CASIMAS (35 and 103 days, respectively), although median time to next puncture was shorter (60 vs. 97 days). Of six patients sampled, all were ADA positive at screening and remained ADA positive until the end of the study. The presence of ADAs did not affect catumaxomabs safety or efficacy. The CSS and tolerability profile for catumaxomab in SECIMAS were comparable to those in CASIMAS. The majority of patients benefitted from a second cycle of catumaxomab. A re-challenge seems to be feasible and safe for selected patients with recurrent malignant ascites due to carcinoma after a first cycle of catumaxomab.

- PURPOSE: This randomized, multicenter, phase III noninferiority trial was designed to test the efficacy and safety of the combination of pegylated liposomal doxorubicin (PLD) with carboplatin (CD) compared with standard carboplatin and paclitaxel (CP) in patients with platinum-sensitive relapsed/recurrent ovarian cancer (ROC).PATIENTS AND METHODS: Patients with histologically proven ovarian cancer with recurrence more than 6 months after first- or second-line platinum and taxane-based therapies were randomly assigned by stratified blocks to CD (carboplatin area under the curve [AUC] 5 plus PLD 30 mg/m(2)) every 4 weeks or CP (carboplatin AUC 5 plus paclitaxel 175 mg/m(2)) every 3 weeks for at least 6 cycles. Primary end point was progression-free survival (PFS); secondary end points were toxicity, quality of life, and overall survival.RESULTS: Overall 976 patients were recruited. With median follow-up of 22 months, PFS for the CD arm was statistically superior to the CP arm (hazard ratio, 0.821; 95% CI, 0.72 to 0.94; P = .005); median PFS was 11.3 versus 9.4 months, respectively. Although overall survival data are immature for final analysis, we report here a total of 334 deaths. Overall severe nonhematologic toxicity (36.8% v 28.4%; P < .01) leading to early discontinuation (15% v 6%; P < .001) occurred more frequently in the CP arm. More frequent grade 2 or greater alopecia (83.6% v 7%), hypersensitivity reactions (18.8% v 5.6%), and sensory neuropathy (26.9% v 4.9%) were observed in the CP arm; more hand-foot syndrome (grade 2 to 3, 12.0% v 2.2%), nausea (35.2% v 24.2%), and mucositis (grade 2-3, 13.9% v 7%) in the CD arm.CONCLUSION: To our knowledge, this trial is the largest in recurrent ovarian cancer and has demonstrated superiority in PFS and better therapeutic index of CD over standard CP.

Tidskriftsartikel (refereegranskat)abstract
- This two-arm, randomised, multicentre, open-label, phase IIIb study investigated the safety and efficacy of a 3-h catumaxomab infusion with/without prednisolone premedication to reduce catumaxomab-related adverse events. Patients with malignant ascites due to epithelial cancer received four 3-h intraperitoneal catumaxomab infusions with/without intravenous prednisolone (25 mg) premedication before each infusion. The primary safety endpoint was a composite safety score calculated from the incidence and intensity of the most frequent catumaxomab-related adverse events (pyrexia, nausea, vomiting and abdominal pain). Puncture-free survival (PuFS) was a co-primary endpoint. Time to next puncture (TTPu) and overall survival (OS) were secondary endpoints. Prednisolone premedication did not result in a significant reduction in the main catumaxomab-related adverse events. The mean composite safety score was comparable in both arms (catumaxomab plus prednisolone, 4.1; catumaxomab, 3.8; p = 0.383). Median PuFS (30 vs. 37 days) and TTPu (78 vs. 102 days) were shorter in the catumaxomab plus prednisolone arm than in the catumaxomab arm, but the differences were not statistically significant (p = 0.402 and 0.599, respectively). Median OS was longer in the catumaxomab plus prednisolone arm than in the catumaxomab arm (124 vs. 86 days), but the difference was not statistically significant (p = 0.186). The superiority of catumaxomab plus prednisolone versus catumaxomab alone could not be proven for the primary endpoint. Prednisolone did not result in a significant reduction in the main catumaxomab-related adverse events. The study confirms the safety and efficacy of catumaxomab administered as four 3-h intraperitoneal infusions for the treatment of malignant ascites.

On Quality Improvement in Gynaecological Cancer Surgery
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: The overall purpose of this thesis was to find medical and surgical treatment methods of improving the perioperative care of gynaecological cancer patients. The specific objectives were to determine whether a single dose tranexamic acid given immediately before surgery for presumed advanced ovarian cancer reduces perioperative blood loss and the need for blood transfusions, and to determine whether postoperative recovery, tissue damage, and inflammatory response markers differ between women operated with robotic and abdominal hysterectomy for low-risk endometrial cancer in an enhanced recovery after surgery (ERAS) programme, and to evaluate costs for hospital stay and postoperative recovery in relation to health impact. Material and Methods: The thesis was based on two randomised trials. The first trial was a randomised double-blind placebo-controlled multicentre study conducted in four hospitals in the southeast and central of Sweden between March 2008 and May 2012. One hundred women with presumed advanced ovarian cancer who had been scheduled for radical debulking surgery were included; 50 received tranexamic acid and 50 received a placebo. The main outcomes were blood loss and red blood cell transfusions. The second trial was a randomised open single centre trial at a Swedish university hospital, which included 50 women with low-risk endometrial cancer scheduled for radical surgery between February 2012 and May 2016; 25 women underwent robotic hysterectomy and 25 had abdominal hysterectomy. Anaesthesia and perioperative care followed an ERAS protocol in both groups. The EuroQol Group form EQ-5D-3L and the Short Form-36 evaluated the health-related quality of life. The Swedish Postoperative Symptoms Questionnaire assessed symptoms perioperatively until six weeks postoperatively. Venous blood samples were collected on several occasions until six weeks postoperatively and were analysed for markers reflecting inflammatory response and tissue damage. In addition, a health economic evaluation was conducted comparing total costs, qualityadjusted life years (QALYs) and cost per QALY between the surgical methods. Results: Total blood loss volume and transfusion rate following surgery in advanced ovarian cancer were significantly lower in the tranexamic group compared with the placebo group. Women with early endometrial cancer treated by robotic hysterectomy recovered significantly faster in the EQ-5D health index, and reached their preoperative level nearly two weeks earlier than the abdominal group. Differences regarding improvement in health-related quality of life (Short Form-36) comprising general health and social functioning were more favourable in the robotic hysterectomy group. Consumption of analgesics, pain intensity, postoperative symptom sum score and length of hospital stay were equal between the groups. The occurrence of complications was an independent risk factor and influenced most of the outcome measures adversely. Postoperative inflammatory response and tissue damage were lower after robotic hysterectomy compared with the abdominal approach. The robotic group gained more QALYs until six weeks after surgery than the abdominal group but the total costs were higher. The total cost per QALY gained was quite high for the robotic procedure. Conclusions: A single dose of tranexamic acid given immediately before surgery reduces blood loss and transfusion rates in advanced ovarian cancer surgery. Robotic hysterectomy in an ERAS programme treating early endometrial cancer leads to a faster recovery in the health-related quality of life than abdominal hysterectomy, the latter being strongly influenced by perioperative complications. Less tissue damage and inflammation might contribute to a faster recovery in the robotic group. Robotic hysterectomy provides more QALYs until six weeks postoperatively but with a substantially higher total cost for the society.
