  • Primary treatment patterns and survival of cervical cancer in Sweden : A population-based Swedish Gynecologic Cancer Group Study
  • 2019

    • 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.

  • High-throughput interrogation of PIK3CA, PTEN, KRAS, FBXW7 and TP53 mutations in primary endometrial carcinoma.
  • 2013
  • Ingår i: Gynecologic Oncology. - : Elsevier BV. - 0090-8258 .- 1095-6859. ; 128:2, s. 327-334
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Endometrial cancer patients may benefit from systemic adjuvant chemotherapy, alone or in combination with targeted therapies. Prognostic and predictive markers are needed, however, to identify patients amenable for these therapies. METHODS: Primary endometrial tumors were genotyped for >100 hot spot mutations in genes potentially acting as prognostic or predictive markers. Mutations were correlated with tumor characteristics in a discovery cohort, replicated in independent cohorts and finally, confirmed in the overall population (n=1063). RESULTS: PIK3CA, PTEN and KRAS mutations were most frequently detected, respectively in 172 (16.2%), 164 (15.4%) and 161 (15.1%) tumors. Binary logistic regression revealed that PIK3CA mutations were more common in high-grade tumors (OR=2.03; P=0.001 for grade 2 and OR=1.89; P=0.012 for grade 3 compared to grade 1), whereas a positive TP53 status correlated with type II tumors (OR=11.92; P<0.001) and PTEN mutations with type I tumors (OR=19.58; P=0.003). Conversely, FBXW7 mutations correlated with positive lymph nodes (OR=3.38; P=0.045). When assessing the effects of individual hot spot mutations, the H1047R mutation in PIK3CA correlated with high tumor grade and reduced relapse-free survival (HR=2.18; P=0.028). CONCLUSIONS: Mutations in PIK3CA, TP53, PTEN and FBXW7 correlate with high tumor grade, endometrial cancer type and lymph node status, whereas PIK3CA H1047R mutations serve as prognostic markers for relapse-free survival in endometrial cancer patients.

  • Revision of FIGO surgical staging in 2009 for endometrial cancer validates to improve risk stratification.
  • 2012
  • Ingår i: Gynecologic oncology. - : Elsevier BV. - 1095-6859 .- 0090-8258. ; 125:1
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Correct staging is a cornerstone in cancer treatment. The FIGO surgical staging for endometrial cancer was revised in 2009. We have evaluated if the revision improved stratification with respect to prognosis in a large prospective multicenter setting. METHODS: 1268 endometrial cancer patients have been prospectively recruited in the MoMaTEC study for the investigation of clinical and histopathological data. RESULTS: Restaging from FIGO 88 to FIGO 09 criteria increased the number of stage I cases from 932 to 979. The majority of the non-endometrioid tumors, down-staged to FIGO 09 stage I, were of serous histology. One third of the patients classified as stage II tumors based on FIGO 88 criteria (FIGO88 IIA) were down-staged to FIGO 09 IA (53%) and FIGO 09 IB (47%). The histological subtype for these cases was mainly endometrioid (86.1%) and high/intermediate grade (77.7%). Patients with FIGO 88 stages IA, IB, IIA and IIIA with positive cytology only, showed similar survival. In Cox multivariate survival analysis adjusting for histopathological variables we found that the revised FIGO 09 criteria improved prognostication. For FIGO stage I patients the adjusted HR was 3.9 (p=0.01, CI 1.35-11.36) for FIGO IB compared to FIGO IA. The independent prognostic impact for the FIGO 09 staging was also confirmed in a subset analysis of patients not subjected to lymphadenectomy and for the endometrioid subgroup. CONCLUSIONS: The FIGO 2009 staging system has improved prediction of prognosis, and is less complex, compared to earlier versions. Careful assessment of myometrial invasion seems particularly important for patients not subjected to lymphadenectomy.
