- Objective: Survival in cervical cancer has improved little over the last decades. We aimed to elucidate primary treatment patterns and survival. Methods: Population-based study of patients included in the Swedish Quality Registry for Gynecologic Cancer diagnosed 2011-2015. Main outcome was 5-year relative survival (RS). Age-standardised RS (AS-RS) was estimated for the total cohort and for the pooled study population of squamous, adenosquamous-, adenocarcinoma. Results: Median follow-up time was 4.6 years. The study population consisted of 2141 patients; 97% of the 2212 patients in the total cohort and the 5-year AS-RS was 71% and 70%, respectively. RS stage IB1: surgery alone 95% vs. 72% for definitive chemoradiotherapy (CT-RT) (p < 0.001). In stage IIA1 74% had CTRL, and 47% of operated patients received adjuvant (CT)-RT. RS stage IB2: surgically treated 81% (69% received adjuvant (CT)-RT) vs. 76% for (CT)-RT (p = 0.73). RS stage IIB: 77% for CT-RT + brachytherapy BT), 37% for RT + BT (p = 0.045) and 27% for RT-BT (p < 0.001). Stages III-IVA; <40% received CT-RT + BT, RS 45% vs. 18% for RT-BT (RR 4.1, p < 0.001). RS stage IVB 7%. Conclusion: Primary treatment of cervical cancer in Sweden adhered to evidence-based standard of care. Areas of improvement include optimising treatment for stages III-IVA, and avoiding combining surgery and radiotherapy. (C) 2019 Elsevier Inc. All rights reserved.

- Objective. The aim of the study was to investigate if time to start chemotherapy (TTC) after primary debulking surgery (PDS) impacted relative survival (RS) in advanced epithelial ovarian/fallopian tube/primary peritoneal cancer (EOC). Methods. Nationwide population-based study of women with EOC FIGO stages IIIC-IV, registered 2008-2018 in the Swedish Quality Register for Gynecologic Cancer, treated with PDS and chemotherapy. TTC was categorized into; <= 21 days, 22-28 days, 29-35 days, 36-42 days and > 42 days. Relative survival (RS) was estimated using the Pohar-Perme estimate of net survival. Multivariable analyses of excess mortality rate ratios (EMRRs) were estimated by Poisson regression models. Results. In total, 1694 women were included. The median age was 65.0 years. Older age and no residual disease were more common in TTC >42 days than 0-21 days. The RS at 5-years was 37.9% and did not differ between TTC groups. In the R0 (no residual disease) cohort (n = 806), 2-year RS was higher in TTC <= 21 days (91.6%) and 22-28 days (91.4%) than TTC >42 days (79.1%). TTC >42 days (EMRR 2.33, p = 0.026), FIGO stage IV (EMRR 1.83, p = 0.007) and non-serous histology (EMRR 4.20, p < 0.001) were associated with 2-year worse excess mortality compared to TTC 0-21 days, in the R0 cohort. TTC was associated with 2-year survival in the R0 cohort in FIGO stage IV but not in stage IIIC. TTC was not associated with RS in patients with residual disease. Conclusions. For the entire cohort, stage IV, non-serous morphology and residual disease, but not TTC, influenced 5-year relative survival. However, longer TTC was associated with a poorer 2-year survival for those without residual disease after PDS. (c) 2024 The Authors. Published by Elsevier Inc.

- Aim. The first Swedish National Guidelines for Ovarian Cancer (NGOC) were published in 2012. We aimed to evaluate surgical outcomes and survival in patients with stage IIIC-IV disease, before and after the NGOC implementation. Method. Women with primary epithelial ovarian cancer, FIGO stage IIIC?IV, registered in the Swedish Quality Registry for Gynecologic Cancer 2008?2011 and 2013?2016 were included. Surgical outcomes were analyzed, including frequency of complete cytoreduction (R0). Relative survival (RS) and excess mortality rate ratios (EMRRs) were computed as measures of survival. Univariable and multivariable regression (Poisson) were calculated. Results. In total, 3728 women were identified, 1746 before and 1982 after NGOC. After adjusting for age and stage, survival was improved 2013?2016 vs. 2008?2011 (EMRR 0.89; 95%CI:0.82?0.96, p < 0.05). For women undergoing primary debulking surgery (PDS), R0 frequency (28.9% vs. 53.3%; p < 0.001) and 5-year RS (29.6% (95% CI:26.8?32.8) vs. 37.4% (95%CI:33.6?41.7)) were increased, but fewer patients (58% vs. 44%, p < 0.001) underwent PDS after NGOC implementation. Median survival for the PDS cohort increased from 35 months (95%CI,32.8?39.2) to 43 months (95%CI,40.9?46.4). In the neoadjuvant chemotherapy (NACT) + interval debulking surgery (IDS) cohort, R0 increased (36.8% to 50.1%, p < 0.001), but not 5-year RS (17.5% vs. 20.7%,ns). Compared to PDS, the EMRR was 1.32 (95%CI,1.19 & ndash;1.47, p < 0.001) for NACT+IDS and 3.00 (95% CI,2.66 & ndash;3.38, p < 0.001) for chemotherapy alone. In multivariable analyses, PDS, R0, age <= 70 years, and stage IIIC were found to be independent factors for improved RS. Conclusion. Implementation of the first National Guidelines for Ovarian Cancer improved relative survival in advanced ovarian cancer. (c) 2021 Published by Elsevier Inc.

- Objective. The aim of the study was to determine survival outcome in patients with serous cancer in the ovary, fallopian tube, peritoneum and of undesignated origin. Methods. Nation-wide population-based study of women 18 years with histologically verified non-uterine serous cancer, included in the Swedish Quality Registry for primary cancer of the ovary, fallopian tube and peritoneum diagnosed 2009-2013. Relative survival (RS) was estimated using the Ederer II method. Simple and multivariable analyses were estimated by Poisson regression models. Results. Of 5627 women identified, 1246 (22%) had borderline tumors and 4381 had malignant tumors. In total, 2359 women had serous cancer; 71% originated in the ovary (OC), 9% in the fallopian tube (FTC), 9% in the peritoneum (PPC) and 11% at an undesignated primary site (UPS). Estimated RS at 5-years was 37%; for FTC 54%, 40% for OC, 34% for PPC and 13% for UPS. In multivariable regression analyses restricted to women who had undergone primary or interval debulldng surgery for OC, FTC and PPC, site of origin was not independently associated with survival. Significant associations with worse survival were found for advanced stages (RR 2.63, P<0.001), moderate (RR 1.90, P<0.047) and poor differentiation (RR 2.20, P<0.009), neoadjuvant chemotherapy (RR1.33, P<0.022), residual tumor (RR 2.65, P<0.001) and platinum single (2.34, P<0.001) compared to platinum combination chemotherapy. Conclusion. Survival was poorer for serous cancer at UPS than for ovarian, fallopian tube and peritoneal cancer. Serous cancer at UPS needs to be addressed when reporting and comparing survival rates of ovarian cancer. (C) 2016 Elsevier Inc. All rights reserved.

- OBJECTIVE: The aim of the study was to evaluate the sentinel node (SLN) concept for lymphatic mapping in early stage cervical cancer. METHODS: 105 women with early stage (1a1-2a) cervical cancer were scheduled for the sentinel node procedure in conjunction with a complete pelvic lymphadenectomy. The day before surgery, 1-1.5 mL 120MBq Tc(99) albumin nanocolloid was injected submucosally at four points around the tumor followed by a lymphoscintigram (LSG) to achieve an overview of the radiotracer uptake. RESULTS: During surgery, the overall detection rate (gamma probe) of at least one SLN was 90% (94/105 women) whereas at least one SLN was identified in 94% (61/65 women) with a tumor 2 cm) node without radiotracer uptake.

- Objective: Vulvar cancer affects mainly elderly women and with an ageing population the incidence has increased. We explored the primary treatment patterns and relative survival of patients with vulvar squamous cell carcinoma (VSCC) by stage and age-group. Methods: A population-based nationwide study on women diagnosed with VSCC between 2012 and 2016 and registered in the Swedish Quality Registry for Gynecologic Cancer (SQRGC). Main outcome was 5-year relative survival (RS) estimated by the Pohar Perme method. The relative risk of excess mortality (EMRR) between different groups was analyzed by Poisson regression. The age-standardized relative survival (AS-RS) was estimated for the total cohort. Results: Median follow-up time was 41 months. The study population included 657 women; 33% were ≥ 80 years old. FIGO stage I was most common (55%). Primary surgery was performed in 96% stage I, 65% stage II, 80% stage III and 28% stage IV. In women ≥80 years, exploration of the groins and chemoradiotherapy was less often performed. They also received lower mean doses of radiation than younger women. The 5-year AS-RS was 74%. 5-year RS was 84% for stage I, 60% for stage II, 54% for stage III and 35% for stage IV. The EMRR for women ≥80 years compared with women <60 years was 4.3 (p < 0.001); 4.9 (p < 0.001) for stages I-II and 3.5(p = 0.007) for stage III. Conclusions: In general, primary treatment of patients with vulvar squamous cell carcinoma in Sweden adhered to guidelines. Areas of improvement include treatment for stage II and for the very old. © 2020 Elsevier Inc.

- Objective. To assess the accuracy and reproducibility of robot-assisted laparoscopic abdominal fertility sparing radical trachelectomy in women with early stage cervical cancer. Methods. Relevant prospective clinical data from 13 consecutive women planned for robotic radical trachelectomy between 2007 and 2012 were compared with retrospective data from 12 consecutive women planned for vaginal radical trachelectomy between 2000 and 2007. The first follow up on all women included a similar vaginal ultrasonographic measurement of the remaining cervical length and the position of the cerclage, enabling a direct comparison. Peri- and postoperative clinical data were evaluated. Results. The remaining cervical length was equal between the robotic and vaginal procedures (mean 11mm, range 8-13mm; mean 11mm, range 5-19mm respectively, p=0.92). The distance from the cerclage to the inner cervical os was significantly shorter and less variable in the robot group (robot mean 2mm, range of 1-4mm, vaginal mean 4mm, range 2-7mm, p=0.003). Rejection of the cerclage (n=3) and/or cervical stenosis (n=3) was diagnosed in four women, all of whom in the vaginal group, between one and 13months after surgery. Conclusions. Robotic trachelectomy is equally reproducible and accurate as the vaginal trachelectomy in terms of the remaining cervical length and results in a significantly more precise placement of the cerclage.

- OBJECTIVE: To evaluate feasibility and morbidity of robot assisted laparoscopic radical hysterectomy. METHODS: From December 2005 to September 2008 robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy was performed on 80 women. Using a prospective protocol, and an active investigation policy for defined adverse events, perioperative, short and long term data were obtained. RESULTS: Time for surgery (skin to skin) reached 176 and 132 min after 9 and 34 procedures respectively. All tumours were radically removed. Median number of retrieved lymph nodes was 26 (range 15-55). All women had an early follow up (1-3 months) and 43 of eligible 46 women (93%) had a long term follow up (>/=12 months). In 33 of 80 women (41%) the peri/postoperative period was uneventful. The remainder had one or more mainly mild adverse events, most commonly from the vaginal cuff (n=17, 21%) or the lymphatic system (n=16, 20%). The proportion of uneventful cases increased significantly over time. Five women were resutured for dehiscence of the vaginal cuff, two women were reoperated for trocar site hernias and one woman had a ureter stricture that resolved following stent treatment. Eight women (14%) needed 60 days or more to resume spontaneous voiding. One 72-year old woman with disseminated endometrial cancer on autopsy died of pulmonary embolism 31 days after surgery. CONCLUSIONS: Robot assisted laparoscopic radical hysterectomy is a feasible alternative to conventional laparoscopy and open surgery. Effort should be made to ensure proper closure of the vaginal cuff, trocar sites and to develop nerve sparing techniques.
